Dear Fahad, Very good question. Although it is not my specific area of research, I believe that you are right in questioning this! Iresearch economic development of Brazil - (B of BRICS) and some econometric models really help. To begin, I would try to help you suggesting: a) ECONOMETRICS - Book from GUJARATI, Damodar N. b) Human Capital Formation - a theme that you should research to understand the importance of "years of schooling" c) PWT 9.0 - Penn World Table - release 9.0 and World Bank as databases where you can have (free of charge) important data to make some essays.

Hi. I'm wondering if you are going to cover only Nepal? Are you having an interest in covering other countries such as Korea, Australia, etc.? I'm currently working on statistical prediction of energy, food demand and population, and I have an interest in more about lifecycle energy demand for food production (not at the moment). So I found this project very interesting. Is there a chance that Nepal would produce biofuel, or using byproduct of farming as energy? Regards, San.
 
Dear Dr. Sanghyun Hong, I am just now seeing your question, sorry. Yes, it would be great pleasure if we can conduct such studies in other countries too. I have done Master Degree from South Korea and I know bit Korea and it's obviously would be much interesting if we would cooperate to conduct studies there too. We can compare the results of different locations to make our study better. Currently I am conducting studies in pre-monsoon rice and maize in Nepal. In Nepal there are many small scale briquettes producing industries and we are working to establish a large scale (>4 ton/hr) pellet industries here. Thank you and have a good day.

To protect American industries and manufacturers, the United States’ President Donald Trump has imposed and will impose specially rated tariffs (import taxes) on certain items. It seems like China is the main target by President Trump; but it is not limited to China. Many other countries, such as South Korea, Japan, India, Mexico, and so on, have been and will be subject to specially rated tariffs. President Trump’s such a drastic measure will make other countries almost impossible to export certain items (e.g., home appliances, automobile, iron and steel) to the United States. What would be consequences of such a drastic measure by President Trump? Are other countries copy President Trump’s such move in an expression of retaliation, which may lead to international trade warfare?

Hello! If you don't have a commercial catalyst sample, you can compare your catalyst only with articles and patents data. Just to study your catalyst in the same conditions that in the liturature. Or you can connect and cooperate with a company/people which have the interes in a new catalysts development. Try to turn directly to researchers who used a commercial sample in their works. To get (synthesize) a commercial catalyst may be problematic since details of preparation and composition catalyst are not disclosed.

Hi, I am a graduate student working for National Creative Research Center for Epigenome Reprogramming Network located in Seoul National University, Korea. The problem is that as you can see the picture "induction test-1" that hte protein was so well induced, however, when I tried to purify the protein of my interest (estimated size:17kda) , the most of it went to inclusion body and showed other unrelated bands in coomasie "purification step-2". In that picture, the first two lanes are 10μℓ and 20μℓ of finally eluted protein(16 ℃ overnight induction with 0.1mM IPTG) each other. The eighth lane is the sample of inclusion body pellet after sonication. The ninth one is supernatant after centrifugation after sonication. I even checked this eluted protein with anti-His(Cell signaling) antibody(in "western anti-His-3" picture) and it showed quite strong expression in other band which should not be mine (because the estimated size is not same with that of the protein). Anyway, I don't have any clue to figure out those problems and have tried to change induction conditions and bacterial strain from BL21(DE3) to Rosetta but did not get the better consequence. If I can not find any solution, I am thinking to resolve the inclusion body into Urea. If you can give me any tips based on your research experience how to perfectly purify this protein, I would be absolutely exalted and grateful to that. Thank you so much.
 
If I understand your situation correctly, then it is not unusual. The overexpressed protein is a mixture of soluble and insoluble protein. The single-step purification by Ni-affinity chromatography with the soluble fraction was not sufficient to purify the protein to homogeneity because some other proteins in the fraction also bound to the column. A 2nd chromatography step is needed. In this case, since the contaminants are of higher molecular weight than the desired protein, a gel filtration chromatography step will probably work well. There is another possibility to consider, however. It may be that the high-molecular weight bands are covalently linked oligomers of your protein, which results from intermolecular crosslinking. This can happen with some SDS-PAGE systems if the anti-oxidant is omitted from the running buffer, or of the reducing agent in the sample buffer is inadequate.

Hello, Fuller rose beetle, Naupactus godmani are commonly found snout beetles in citrus groves. They do not cause economic damage in citrus, but the presence of viable eggs on fruit exported to other countries such as Korea can be a trade barrier - it is a quarantine pest in Korea. This beetle is parthenogenetic (all females) and reproduce without mating. Any reference to on managing parthenogenic populations of insects would be helpful.
 
The problem with the proposed PDF might be, that the reproduction and foraging of chironomids (Diptera) obviously is much different from Coleoptera. Many approaches either target the flying adults (avoidance of oviposition) or target the merolimnic larvae. The reproduction is different in Naupactus godmani. I would assume that references dealing with the managing of beetle populations in general might be helpful as well, at least if they don't target the mating process, or the males. e.g. Cavanagh et al. 2009 (J. Econ. Entomology), Choo et al. 1996 (J. Econ. Entomology) and similar.

But at other universities, a senior lecturer can be promoted to a reader--the more senior rank. In these cases, the senior lecturer can be seen as an associate professor and the reader as a full professor without a chair. At Oxford, a reader is an intermediate position between an associate professor and a professor, however the university has stopped appointing new readers. https://en.wikipedia.org/wiki/Reader_(academic_rank) A more accurate analogy: Lecturer=Assistant Prof Senior Lecturer=Associate Prof Reader=Professor Professor=Chaired Professor There are always situations that look like exceptions, of course, but in the humanities at least you really need to have two books in print to get to Reader. https://www.chronicle.com/forums/index.php?topic=202243.0

hello, I am master degree researcher from South Korea. I made some materials following another researchers. But unfortunately, my reaction needs DMSO for solvent. as you know, DMSO has very high BP(around 180oC, as I know of). I used vaccum rotary evap to evaporate DMSO but I failed. also I used vaccum oven around 120oC, it has failed too. finally I precipitated mixture with poor solvent, but it still had some traces of DMSO. The reason why I've been trying to get rid of DMSO out of my sample is to get solid state of it. The trace make it very sticky liquid state so it's hard to applicate anywhere else. My sample is very soluble in water, so I doubt water-wash can extract DMSO from my sample. How can this get done?? Please give me some advices. and sorry for my poor english skills :(
 
Do I understand correctly, that you want to get rid of DMSO, w/o heating the reaction solution to 180 °C? In case your products are not volatile, you might want to try vacuum distillation, aka "speedvac". The sample is cooled during the automated evacuation process... Hope this is what you have in mind?

Most jobs nowadays require us to focus for long periods of time. The trouble is, we think our ability to concentrate is unlimited. Truth be told, the human mind wasn’t meant to be hyper-focused for terribly long periods of time. So how can we hack our brain to squeeze out the most concentration out of it? Many other studies back up the strategic break hypothesis. A 1999 Cornell University study for instance, found that when workers were reminded to take breaks periodically, they were actually 13% more accurate in their tasks. South Korea, which has some of the most hours worked in the world, ironically has a low productivity rate. As a result, the government recently instituted a country-wide 52 hour work week, down from 68 hours. What is your perspective?
 
Essentially, it's important to give young people the opportunity to do research. But no matter how or why you go about it, do not think of retirement as an end. Stopping doesn't mean stopping. It means do what you've always wanted to do. I agree with all of your affirmative comments dear colleagues.

Calculations in such problems are based on the 3D approximation of curves and surfaces. Surface approximation can be narrowed down to a function of one variable. A type of multifunction interpolation (see article I in the journal) is proposed. Errors are estimated and circular arc interpolation convergence is proven. A brief description of practical application of the method is given.

Trump is no doubt a disagreeable individual, but dismissing all his actions is not perhaps wise. Stopping political dichotomies, or at least not constructing them with all their potentiality towards war may be a good thing (resolving the Russia-USA antagonism, USA-North Korea)-but is it? Does that leave the West open to betrayal?
 
Are we really sure "Trump is attempting to stop the conflict positions between states"? Is it really the fact that he is trying to resolve "the Russia-USA antagonism, USA-North Korea" uncertainties? Maybe we may have to wait for a little while before we can be sure what President Trump really wants. When a president picks multiple economic confrontations with several countries at the same time (including supposedly historic allies and friends), bearing in mind that these economic confrontations may have ripple effects on security (especially when the same president and his administration have labelled economic competitors as "threats" to national security), what can we expect? Will tearing down globally accepted agreements and seeking excessive nationalism and unilateralism amidst disrespecting other sovereign states and world leaders ensure removal of political dichotomies? How can selling billions of arms to some presumably hostile states and supporting a course that motivates the killing of innocent civilians in the middle east guarantee peace? I am just wondering what really the President is seeking. Maybe, we just need to really understand what "the art of the deal" is really is. At least for now, maybe if he intends "to stop the conflict positions between states", he should not just be trying to hangout with Putin. He should also look at the plight of Syrians and Palestinians. He should take a closer look at the shattering Iran nuclear deal and the consequences of ill-advised policies that triggers unnecessary hardships for people across the world. Talking of trust, I will simply say trust MUST BE earned.

Manganese is transition element, Manganese (Mn) is an essential trace metal with insufficient intake in virtually all diets. It has been reported that Mn is involved in normal immune functions, regulation of blood sugar and cellular energy, and the defense mechanisms against free radicals [1,2]. Experimentally induced Mn deficiency caused a number of detrimental effects, such as impaired bone formation, abnormal glucose tolerance, low levels of high-density lipoprotein (HDL) cholesterol, and skin abnormalities in both animals and humans [3]. Conversely, excess occupational inhalation of Mn may be neurotoxic to humans, producing effects such as psychosis and Parkinsonism. Mn deficiency and intoxication are both associated with adverse metabolic and neuropsychiatric effects [4,5]. Nevertheless, little is known about the optimal blood Mn levels for maintaining homeostasis in humans. One study found that Mn inhalation in adult animal models markedly down-regulated the gene expression of proteins critical to inflammatory responses or possessing pro-oxidant properties (e.g. tumor growth factor (TGF)-β and neuronal nitric oxide synthase (nNOS)) [6]. These results suggested that a certain amount of Mn exposure may attenuate the inflammatory response to stressful environments. In contrast, Mn is an essential cofactor for metalloenzyme superoxide dismutase, which protects cells against antioxidant processes [3]. Malecki et al. demonstrated that Mn deficiency and the resultant decrease in manganese superoxide dismutase (MnSOD) activity caused heart mitochondria to be more sensitive to in vivo oxidative damage [7]. This study proposed that subclinical Mn deficiency might also contribute to excess oxidative stress. Oxidative stress and inflammation are the main pathophysiology behind most chronic diseases. Therefore, we hypothesized that blood Mn levels could be related to the prevalence of chronic diseases. We conducted a cross-sectional analysis on the associations of blood Mn level with five chronic diseases (diabetes, renal dysfunction, hypertension, ischemic heart disease, and stroke) in a representative sample of the adult Korean population from the Korean National Health and Nutritional Examination Survey (KNHANES). Go to: Methods Study population The KNHANES was performed to examine the general health and nutritional status of the civilian, non-institutionalized Korean population. KNHANES is a cross-sectional and nationally representative survey composed of a health questionnaire, a health examination, and a nutrition survey. The fourth KNHANES (KNHANES IV) was conducted from 2007 to 2009 using a stratified, multistage probability sampling design. We used data from the second (2008) to third year (2009) of the KNHANES IV. Of the 8641 individuals who participated during this time, we analyzed those who were 20 years of age or older and tested for blood Mn. We excluded participants who were pregnant or had missing values and yielded a final sample size of 3996 adults. The Catholic University of Korea Incheon St. Mary’s Hospital Institutional Review Board and the Korea Centers for Disease Control and Prevention approved the study protocol, and written informed consent was obtained from all participants before the study began. Laboratory measurements Blood Mn was measured using whole blood at the Neodin Medical Institute (certified by the Korean Ministry of Health and Welfare) in Seoul, Korea, following a standardized protocol. Blood Mn was analyzed by graphite furnace atomic absorption spectrometry with Zeeman background correction (Perkin Elmer AAS800, Perkin Elmer, Turku, Finland). The limit of detection was 0.016 μg/dL for blood Mn. For internal quality assurance and control, standard reference materials were obtained from Bio-Rad (Lyphochek® Whole Blood Metals Control). The inter-assay coefficients of variation ranged from 0.95% to 4.82% for blood Mn samples (reference values were 0.98, 1.18, 2.46, and 3.28 μg/dL). During the survey, overnight fasting venous blood samples were collected. The collected blood samples were properly processed, refrigerated, and transported in cold storage to the Neodin Medical Institute in Seoul, Korea. Chronic diseases Diabetes was defined as having one of the following: a fasting blood glucose ≥ 126 mg/dL, a self-reported physician’s diagnosis, medication use, or insulin administration at the time of interview. Serum creatinine level was measured using a Hitachi Automatic Analyzer 7600 (Hitachi, Japan) and a modified kinetic Jaffe reaction. The level of kidney function was attained using an abbreviated equation developed from the data from the Chronic Kidney Disease-Epidemiologic Collaboration Group (CKD-EPI) study to estimate the glomerular filtration rate (GFR) [8]. We defined renal dysfunction as an estimated GFR (eGFR) of 
 
Manganese has been recognized for many years,as essential for human as , Mn levels in brain tissue average approximately 1–2 µg/g dry weight. The concentration of Mn in the brain varies across brain regions under excessive exposures. Importantly, the highest Mn levels are found in the globus pallidus in humans and in the hypothalamus in rats [9, 10]. Excessive and prolonged exposure to Mn resulting from occupations such as welding and mining, inhalation of combustion products from the anti-knock agent in fuel (MMT) and highly concentrated Mn concentrations in ground/well water leads to Mn accumulation in the dopamine-rich regions of the basal ganglia. In fact, spectroscopy in rats has demonstrated that mitochondria in the basal ganglia accumulate the highest amount of Mn following exposure [11, 12]. This causes a clinical disorder referred to as manganism that is characterized by a set of extrapyramidal symptoms resembling idiopathic Parkinson’s disease (IPD) including anorexia, apathy, and muscle and joint pain. Shortly after the onset of these symptoms, patients also exhibit memory loss, compulsive behavior, visual impairment, illusions and delusions, and disorientation, which is clinically referred to as locura manganica, or manganese madness [13]. Mn overload affects two vital organs, the brain and lungs; the latter results from inhalation [14, 15]. Elevated Mn levels in the brain have been associated with impairment in iron homeostasis, excitotoxicity, mitochondrial dysfunction, oxidative stress, induction of protein aggregation, and alteration in the homeostatic conditions of other divalent metals that share similar transporter systems with Mn. Although the relationship between increased Mn levels and its disruptive effects on the neurochemistry of neurotransmitters has been debated, elevated Mn has been suggested to alter concentrations of γ-aminobutyric acid (GABA), dopamine, and glutamate neurotransm.so the manganese has great role,

whether academics conferences is just for the sake of presenting papers or valuable ... i got an chance to present a paper in a conference .... conducted by WSEAS .... is it worth to travel such distance( india to korea ) to present a paper ...... pls ..... give some suggestion ......
 
I would answer with a conditional yes; however, you need to think about the QUALITY of the conference. I'm not going to comment on the quality of WSEAS, other than to say there are reputable conferences and then there are many others who will accept almost every submitted paper including randomly generated ones, basically as a money-making scam. Be very careful where you submit your work. In our field, I suggest concentrating on international conferences sponsored by the IEEE, IET or ACM. Things to look out for are full peer review (abstract only paper submission usually indicates weak or no peer review), a low acceptance rate (should be less than 1/3, preferably less than 20%), accepted papers indexed on reputable publication databases (such as IEEExplore), conference is sponsored by a reputable organisation, and conference has been around some years with a good track record (e.g. IEEE Globecom or ICC in telecommunications). The technical program committee should also consist of a wide selection of people from different institutions with strong recent track records in top (high impact) journals. The actual value of conference publications in terms of your research track record is often quite low - many funding bodies now only want to see a list of your journal papers. However, the main reason to attend a conference is (as mentioned by others) to see what others are doing, get some new ideas, and network with your peers. Weak conferences don't offer that opportunity because they do not attract high quality researchers. If you are a PhD student - my advice is to focus first on journal papers, and once you have a few (again, in REPUTABLE, HIGH IMPACT journals such as IEEE Transactions) then only consider presenting specific aspects of that work (e.g. applications of the theoretical work from the journal paper) in conferences AFTER you have the journal paper accepted. For a research career, this will add much more value to your work - it is also a lot cheaper (typically free if not overlength or open access, whereas a conference costs you the airfare, accommodation, registration etc. - potentially thousands of dollars).

I'm working on a contrastive study for my university final project and I need some insights into the methods, approaches and resources used to teach spanish as a foreign language.
 
I. Linguistically At my university, we taught it primarily through TPR, modified by TPRS as the students progressed. As the language-of-instruction, we mostly used English, with only occasional use of Korean.  All of my students (mostly Koreans, but a few from China and SE Asia) except for one spoke English at a fair to excellent level.  For the one student who spoke practically no English; when we had need to explain or translate some-thing, either I explained in Korean  or I had a Korean or other Chinese explain it in Korean or Chinese. One disappointment or minor frustration, especially in the beginning, was that even with students with TOEIC scores or 900, cognates that are obvious to native speakers of English were opaque (at least until pointed out) to them.  On the other hand, once pointed out, the cognates did seem to stick. The fact that the subject can often be left out in both languages meant there was no problem For pronunciation, four things stood out: 1) Both Spanish and Korean have pure vowels, so I stressed that my students had a better accent than I (a gringo) have and that they should model after native speakers (some semesters I had some who helped me in the classes). 2) Maybe even more than Americans,  most of the Korean students had a real problem rolling Rs. 3) Spanish and Korean are both syllable-based (for Spanish, more or less), so this was easier for the students than getting the right rhythm in English. 4) Questions have pretty much the same intonation in Spanish and Korean, so this was simple for the students to learn. In America, a Spanish teachers can assume that her students know at least a small number of Spanish /Mexican words such as uno, dos, tres,  lasso, canyon, pinata, taco, tortilla, and Hasta luego.  This cannot be assumed for Korean students. I would like to note that  my students' English improved  through their Spanish classes, especially in learning cognates that are less common in English but basic vocabulary items in Spanish (especially words where English has a Germanic synonym or near-synonym, such as discover/find). II. Administratively I started teaching Spanish as a non-credit, informal class, with the goal of getting students' success to convince the administration to offer it as  a second- foreign-language option and maybe even a minor.  Later, it was briefly offered as a regular elective course  but then downgraded to a club.  During the first period with the non-credit classes,  after we hired a TEFL instructor who was also an experienced high-school Spanish teacher, we were able to offer classes by two different instructors, with the idea that the other instructor would teach advanced courses.  As it turned out, he left before our students got that advanced. Later, a new EFL instructor who is a native bilingual was hired, and he joined me in teaching Spanish. The classes were taught once a week for 50 minutes some semesters and twice  a week for 50 minutes. Students expressed an interest in continuing classes between semesters, but in fact that never panned out. At an EFL conference, we met some-one at a near-by university and attempted to set up some sort of cooperative  arrangement.  For what-ever reasons, this did not take off.

Less is known about North Korea which is a hermit country. It is through the photography the world is able to unravel the culture and society of the country. The question is whether these visual representations are rooted in the visual politics of United States or they represent the true side of North Korea which is a land of atrocities and where human rights are denied. 
 
If you refer to official documents of North Korea, I am afraid, the access might be limited, almost impossible to find on the internet. Though you might ask such well-known specialists on North Korea as Leonid Petrov (Australia), Andrei Lankov (Korea / Australia) or Immanuel Kim (USA), to name only few of them.

Culture undoubtedly plays a major role.  Both the Middle East and Korea have patriarchal societies that are collective societies:  the needs of the community are greater than the needs of the individualism. I believe the answer to the issue of women's rights lies in this:  advocates demand too much too quickly, before the women who live there really know what they want, and they try to impose top down solutions. In Britain and the United States, women's rights (suffragette) movements took decades to gain any traction.  In the United States, the women's rights movement had to take a back seat to the anti-slavery movement; women waited over sixty years before they finally made any real gains by gaining the Constitutional right to vote.  Gender bias was still a major part of society for decades after that, and women still struggle to break the glass ceiling. In Saudi Arabia, women finally have the right to vote.  They're trying to get the right to drive.  Women's rights activists have two things going for them:  they're not demanding too much too soon (they understand they have to placate entrenched patriarchal interests disguised as religion), and their King wants reform. If the King did not want reform, it would not happen at all. In South Korea, rapid industrialization and increases in social wealth and prestige for the society have created a lot of opportunities for women, and the society has imitated how Japan benefited from women in the work place.  However gender roles are still strongly entrenched, in spite of more equal rights on paper. In Pakistan, the issues are complicated by years of regional conflict under the guise of religious conflict.  The Pakistani Taliban has taken a page from the Afghanistan Taliban and liberally uses terror to keep women in pre-defined roles.  Even the heroism of Malala hasn't done much to change that.  Women and girls are killed or maimed frequently, especially in the loosely governed tribal areas along the Afghan border.  There won't be a solution in Pakistan until the government abandons its obsession with India and resolves to govern effectively throughout the entire country.

Please leave your thoughts and opinions thank you =)
 
I've seen these kinds of questions before and they always lead me back to Victor Hugo and his theory of architecture and his ideas about great architecture and how it has a language of its own. This was important in a pre-literate society before signs and labels. But this is still true today. We know, for example, something "important" happens, say, at the U.S. capital building just by its sheer size and grandeur. Buildings speak to us, even in their seeming silence. I mention Hugo as a worthwhile read and as a jumping off place whenever considering the inherent language of architecture.

Fiedler has said it all. Hardy-Weinberg hsan equation that is ver well used to calculateallelic equenies in thepopulation. The equation producesa good resultpvided l the conditions of equilibrium are met. The phenotypic ratio relates with the alllic ratio exactly the way Mendellian phenotype relates with the Mendellian genotype. This remains so provided that inheritance of the factors being considered obey Mendellian principles. The factors involved here must not beaafected by other genetic phenomena such as retro elements and, their expression must not be affected by other factors that could be affected by other factors that are easily modified by such phenomenon as retroelements as well. Under normal genetic circumstances, phenotypic ratios in a population remain stable.
