ABSTRACT
The problem associated with design errors and incomplete drawings is an old but recurring problem in the Nigerian construction industry. The study examined the impact of design errors and incomplete drawings on construction project delivery in Nigeria. The data for this research were obtained from both primary and secondary sources. A total of 110 questionnaires were distributed to building contractors, selected clients, Architects, Engineers, Builders and Quantity Surveyors. Out of the 110 questionnaires administered, 45 were retrieved and considered fit for analysis. Convenience sampling technique, type of non-probability techniques and stratified sampling technique, a type of probability sampling technique were adopted. Frequencies, percentages and relative importance index were adopted in analyzing and ranking the results. The study revealed that consultants, contractors and clients were the major stakeholders mostly implicated in design errors and incomplete drawings. The results indicated that late or inadequate instructions from client, regular interference by client, inadequate site investigation by design consultants, inadequate and unclear documentation by design team, hurry to meet-up with client unrealistic deadline, lack of constructability reviews in design, lack of clarity and technical professionals in the contracting firms were ranked most as the cause of design errors and incomplete drawings. Findings revealed that construction project delays, construction cost overrun, rework (both in design and construction), accidents, contract disputes, contract failure, loss of life and re-estimation of work statement were ranked most as the impact of design errors and incomplete drawings on construction project delivery. The study concludes that comprehensive site investigation should be carried out at the design phase of the project in order to avoid variations that are likely to occur during construction. All aspects of possible changes should be considered thoroughly before construction begins in order to avoid undue changes and delays. Also, there is need for construction design to pass through constructability reviews with a view to reducing construction cost, less interference, shorter construction times and fewer claims. Design team should be encouraged to use building information modeling during design.

ABSTRACT
The relevance of development associations in any democratic setting cannot be over looked. This paper aimed at identifying development associations, explained the roles of development associations on rural transformation identify the challenges faced by these associations and make possible suggestions on how these challenges can be addressed. the paper revealed that despite the contributions of development associations to national growth, development associations are faced with the challenges of poor adherence to tenure, impatient, gender insensitivity, lack of accountability, poor meeting attendance, poor decision taking, poor political game plan and will (apathy), government interference (sovereignty), poor attitude to elections, leaning to political party dimension ( unhealthy for development associations), leadership crisis, ethnicity (clan),self centeredness/ disrespect for elders and the role of traditional leaders. In order to dress these problems, the paper suggests increased awareness at the community level on the formation of development associations. development associations should seek for ways of partnering with all the tiers of government for development projects in rural communities, Government should encourage development associations by supporting their developmental efforts or by subvention, there should be effective collaborative programs and strategies with an effective and efficient leadership structure, Strategizing to ensure sustainable development in Nigerian local communities, through empowerment of the people should be promoted, development associations in Nigeria should make efforts to fashion out ways to get rid of the increasing challenges posed by poverty, malaria, HIV and AIDs, oppression, political and socio-economic powerlessness among others.

ABSTRACT
This study seeks to investigate and compare the degree of entrepreneurial inclination of Architects and Quantity Surveyors in Nigeria. The study used both the primary and secondary sources of information. The study adopted an exploratory approach using a descriptive survey design based on entrepreneurial intention models. The instruments used comprise of two variables (entrepreneurial characteristics, and entrepreneurial attributes) towards entrepreneurship. The proportionate stratified sampling was used and each stratum represents a profession. A semi-structured questionnaire and interview were developed and administered to 40 registered Quantity Surveyors and Architects each. The main finding of the study was that the two professionals have the characteristics and attributes of an entrepreneur. In conclusion, opportunities avail themselves in the construction industry for the professionals (Architects and Quantity Surveyors) to utilize so as to increase their contributions to the GDP and create employment. The study recommends entrepreneurship as an integral part of each career and not an alternative to job and wealth creation.

ABSTRACT:
The project investigated the use of discriminate function analysis on students’ performance in senior secondary school. And more importantly, to determine which of the variables: Mathematics, English, Biology, Physics and Chemistry discriminate between two groups of students who are (1) above average (2) below average with regard to predetermined classification on the basis of affective domain. Leadership private secondary school Damaturu was chosen because it has students from all geopolitical zones of the country. The research personnel considered sample of eighty five (85) students, where 61 of the students who performed above average on the basis of affective domain is taken as group A, while the remaining 24 students were taken as group B on the same basis and for each group, a corresponding continuous assessment in Mathematics, English, Physics, Biology and Chemistry was collected. The outcome of the test shown that English and Mathematics contributed more to the discriminate function and that, 131.9% of the variance is accounted for. Also, all the variables are significant at 0.01 level of significance which explains that 91.8% of the variables are correctly classified on the basis of affective domain by the teacher. This is further confirmed by chi-square test of independent at 0.01 significant level of 1 degree of freedom.

ABSTRACT:
This project investigated the effect of nutritional status of junior secondary school students on their educational achievement. The study combined the descriptive survey and quasi experimental approaches, the Federal Polytechnic secondary school was chosen because it has students from all geopolitical zones of the country. The researcher personnel measured weight of students using beam balance and their heights using a graduated wall. These were used to measure BMI. The academic achievement of the students was determined using the last end of term scores which were obtained from their school. The mean score which describe the overall performance of 86 students was calculated as 49.3. The calculated BMI index of each student reveals that 67% of the students fall below the normal BMI index which in turn explains why the general performance of the students is below average. The mean of the average performance of the three groups of students categorised by the BMI index as underweight, normal weight and overweight were compared using ANOVA test with Excel Package. The outcome of the test shows that each group can still perform above average independent of their nutritional status. Confirming this was the correlation analysis which shows that there was no relationship between the BMI indexes and the average performance of the students. This explains why some Nigerians students still excel academically despite their poor nutritional status. But this does not override the importance of nutritional food intake, as it is an integral part of academic excellence.

ABSTRACT
The green chemistry revolution is providing an enormous number of challenges to those who practice chemistry in industry, education and research. With these challenges however, there are an equal number of opportunities to discover and apply new chemistry, to improve the economics of chemical manufacturing and to enhance the much-tarnished image of chemistry. The range of chemical products is enormous and these products make an invaluable contribution to the quality of our lives. Hazards could be physical (being explosive or flammable), toxic (being carcinogenic or lethal), or global (climate change or stratospheric ozone layer depletion). The aim of green chemistry is to reduce chemical related impact on human health and virtually eliminate contamination of the environment through dedicated, sustainable prevention programs. Green chemistry searches for alternative, environmentally friendly reaction media and at the same time strives to increase reaction rates and lower reaction temperatures. This paper reviewed the principles of green chemistry, its applications, benefits to human health, environment and the economy.

ABSTRACT
This paper examined ways by which construction material resources can be optimised towards sustainable resource preservation. Material waste in construction contributes between 30-35% of project cost; thus leading to material loss and project cost overruns. Lack of concern by Governments and developers globally and Nigeria in particular is continuously affecting the use of these resources and leading to frequent visit of these materials natural reserve. The optimum use of these resources collectively leads to its sustainability. Questionnaire method has been used. A total of 100 questionnaires were administered to construction practitioners; 80 were returned giving 80% response rate. This was analysed using Descriptive Statistics. The objectives cover the extent of challenges on material resource optimization considering societal value systems in the Nigerian construction industry, investigated the major sources of material wastage at various construction stages and means of material resource optimisation were evaluated. The finding depicts that status symbol mentality by most users of material resources and flawed socio-cultural attitudes to material resource usage have been the highest resource optimization challenges in Nigeria construction industry. The research further ascertain that manual labour assumption during the bill rate computation, ordering too much/too little materials at a time and material handling during construction by contractors are the major factors that contribute to material wastage. Lastly, the study establish options should be considered as means for material resources optimization and include use of experienced and competent personnel to man the construction process, use of standard specifications and adoption of supply chain management. It recommends that better utilization of resources through lean production and prefabricated component processes, use of appropriate equipment and specification, recycling/re-using of old materials for new construction projects will assist greatly in reducing visiting of base materials, hence leading to resource optimization and protection of the environment.
