    ABSTRACT: The purpose of the study was to explore some issues of students’ industrial training programme at Kumasi Polytechnic. Data were collected from 282 students by simple random survey through self completion questionnaire based on a four point Likert scale. Data were analyzed using descriptive statistics and one-way ANOVA. The findings revealed that the overall state of preparation of students for the attachment programme was suitable. The study established, among the challenges that students had competition for attachment places from other institutions, tough work environment for students, high expectations by firms; financial challenges and lack of appropriate skills, tasks and jobs. Finally, strategies that could improve the attachment programme were proposed and it summed up as strong relationship between the Polytechnic and industry. It was recommended that Polytechnic education should be given the needed resources and recognition to produce graduates who may end up solving the problems of the nation. Keywords: Kumasi Polytechnic, industrial attachment, education, graduates, industrial liaison office and unemployment

    ABSTRACT: Cola nitida and Funtumia elastica are two lesser-known species in Ghana that are not used for commercial timber purposes. The objective of this study was to determine the susceptibility of Cola nitida and Funtumia elastica to some drying defects as the basis for determining the potential uses that may encourage the utilization and promotion of these two lesser known species. The basic drying characteristics were determined using the quick drying test method developed by Terazawa. The experimental results revealed the following degrees of defects; checks in the early stages of drying were less severe in both species (Class 3). There was no honeycombing (Class 1) in both species as well as no deformation (Class 1) in both species. This in turn may be followed by an evaluation of their utilization potential, marketability and performance, so as to serve as suitable substitutes for the fast-diminishing traditional market species in Ghana.

    ABSTRACT: Integrated Community Centre for Employable Skills (ICCES) is an agency under the Ministry of Employment and Social Welfare with policy objective of filling the gap in employment generation by developing the young human resources in line with the poverty alleviation goal of the government of Ghana. The purpose of the study was to find out how the ICCES training programmes are achieving their purpose of increasing access of young person’s to skills acquisition and empowerment for productive employment. To harness the needed information, questionnaire, interview and observation, were employed in gathering data from the subjects. The results suggest that participants in the survey had all conferred that the programmes have being helpful to the communities in securing suitable employment that allows them to generate income within the social, family and financial constraints that they face in their communities and as such their social and economic status has being impacted positively.

    ABSTRACT: In Ghana, many of our traditional wood species are over exploited and threatened to extinction. The utilization of other lesser-used and lesser known wood species needs to be looked at urgently as a possibility of increasing the wood resource base. And a successful expansion of the resource base is dependent on adequate knowledge of the properties of the lesser-used species such as Allanblackia parviflora which can be a good substitute to some of the dwindling species. It was against this background that the strength and some physical properties of Allanblackia parviflora trees were determined to predict the suitability of the species for furniture production and structural raw material for downstream processing of wood products. Three Allanblackia parviflora trees were used for the study. The main statistical tools used were descriptive statistics and one-way analysis of variance (ANOVA). Mechanical strength test specimens were prepared and tested in accordance with the British Standard BS 373: 1957. Mean green moisture content was 81.19%. Mean basic density was 539.00kg/m3. The range of mean strength values in N/mm2 in the ‘green’ and dry (12 % M.C) conditions for the three wood species were as follows: Modulus of Rupture: 50.00 - 56.00 (85.00 - 94.00), Modulus of Elasticity: 6,387.00 - 6,951.00 (8,287.00 - 8,875.00), compression parallel to grain: 24.00 - 28.00 (13.00 - 14.00) and shear parallel to grain 6.83 - 7.74 (9.62 - 10.82). Mean ratios of dry to ‘green’ MOR and MOE were 1.68 and 1.28. Almost all strength tests conducted showed a consistent trend that, the heartwood portion of each division was slightly stronger in terms of resistance to failure than its corresponding sapwood portion. Comparing the strength of Allanblackia parviflora to an existing classification (grade), strength is ‘medium’ in Allanblackia parviflora tree wood. It compared favourably with known species such as Aningeria altissima, Terminaria ivorensis, and Antiaris toxicaria in several properties and strength which are suitable for furniture production.

    ABSTRACT: Musculoskeletal symptoms are one of the health problems among institution workers in Ghana. In Ghana, ergonomics principles important in the design and selection of office furniture to ensure that it will avoid any undue strain on the user have not been addressed and documented. Whether or not these strains are related to institution furniture has yet to be determined and published data on furniture size are lacking. The purpose of the study was to determine whether the design of furniture in institutions is appropriate for workers’ anthropometry. The work included a sample of 261 working population (163 males and 98 females) having the age range of 24 – 59 years from six public institutions in Ghana. The data collected included demographic information, data on perceived health and body and furniture measurements. The females’ BMI was higher than that of the males. The females had wider hip breadth measurements in the sitting position. Only few of the participants had a chair with an appropriate seat height. Seat depth was found appropriate for large groups of workers. The study recommended that the design, manufacture and procurement of the office furniture should be based on body measurements of users.

    ABSTRACT: This study was carried out to determine some physical properties of Cola nitida and Funtumia elastica two lesser-known timber species in Ghana that are not used for commercial timber purposes. The basic properties were determined based on British Standard 373 (1957). The main statistical tools used were Descriptive Statistics and Analysis of Variance (ANOVA). Variation in physical properties was analyzed within the trees of the two species. Three trees each per species were used in the study. Results of the study showed that initial moisture content were 66.6% and 79.4% for Cola nitida and Funtumia elastica respectively. The basic density of Cola nitida was 623.8 kg/m 3 and 499.6 kg/m 3 for Funtumia elastica. According to TEDB (1994), Cola nitida is a Medium-Heavy species and Funtumia elastica a Medium Weight species. Mean total tangential shrinkage from green to oven-dry was 7.25 and 6.78% for Cola nitida and Funtumia elastica, respectively. Mean partial tangential shrinkage from green to 12% MC is very small (under 2.5%) for Cola nitida and medium (4.0-5.5%) for Funtumia elastica. The corresponding mean partial radial shrinkage values also showed that shrinkage was very small (under 1.0%) for Cola nitida and medium (2.0–3.0%) for Funtumia elastica. The technical values for the two species compared favourably with those of some locally used species for timber production (like Scottellia coriacea and Lannea welwitschii), and therefore could be considered suitable for timber utilization. The results of the analysis of variance (ANOVA) revealed that the three axial sections of the trees showed significant differences at 5% probability level (p < 0.05).

    ABSTRACT: The study investigated the leadership effectiveness of leaders of tertiary institutions in Ghana. The study sought to examine the leadership styles adopted, the leadership energy and effectiveness of the leaders of two tertiary institutions. The research was undertaken at two institutions; one Polytechnic and one University. The population of the study was the lecturers and the heads of departments of the two institutions. The leadership matrix and leadership effectiveness index questionnaires were employed to collect quantitative and qualitative data. The preferred and practiced styles were compared and contrasted to determine whether or not they were used to achieve goals and objectives of the lecturers and the organizations. Cottrell’s leadership energy formula E=MC2 was used to determine the energy level of the two institutions. The data collected reflected that the leaders of both institutions have adopted team leadership style where they are concerned about the organizational goals and also concerned about the wellbeing of the lecturers. The conclusion drawn was that there is effective leadership with high energy that motivates lecturers in our tertiary institutions. The study ended by making recommendations that encourage high concern for production, the lecturers and the institutions resulting in sustainable ways of achieving the goals and objectives of the institutions and the lecturers. The recommendations contribute towards the academic and professional development of the lecturers and their institutions.

    ABSTRACT: This study was carried out to assess the attitude of artisans towards safety at the Sokoban Wood Village Enclave (SWVE). 208 master craftsmen and apprentices participated in the study. A modified safety culture questionnaire comprising of five themes on work safety was used to collect data for analysis. Data analysis was done using descriptive statistics and one-way ANOVA. Results of the study showed that artisans do not receive training and supervision, have no safe work procedures, are not consulted as well as involved and receives no commitment from management on safety issues. On the contrary, there is a way of reporting safety. The study concluded that the safety culture at SWVE is not health-oriented culture and does not promote safety contrary to safety experts and as such reduce productivity of workers at the enclave. It was recommended that artisans should be educated on work safety and other related studies.
