This study is on capacity building and attitude to work of librarians in Edo State public libraries, Nigeria. Investigation was on the capacity building programs in the Edo State public libraries, the levels of librarians' awareness and participation in the programs, methods of building the capacity programs, influence on the librarians' attitudes to work and factors militating against the programs. Descriptive survey design was adopted for the study and the entire population of 23 librarians were used. Results indicate that the capacity building programs in the library include computer literacy skills, online public access catalogue (OPAC), Internet collection management and general trends in librarianship. The methods used in building the capacity programs in the library include conferences, workshops/seminars, on-the-job and internally organized courses. Respondents indicated very low level of participation in the programs and a negative influence of the programs on their attitudes to work. Various problems were identified as militating against the capacity building programs and solutions were suggested.

Korea Government have carried out various policies to save the Earth environment from global warming and environmental pollution. It has also executed the Green Building Certification Criteria(GBCC) in 2002. The GBCC of office building was executed in 2003 and was revised twice in 2010 and 2011. Concerns about green building construction were quite increasing to keep the building performances sustainable. The aims of this paper is to check the reliability of weighting factors and scoring difficulties in all assessment categories of GBCC and to suggest the amendment direction of the future assessment criteria for green building. For the study, the old and new version of GBCC were examined to present the revision direction of GBCC and the 10 cases certificated by the old and new version, respectively 5 were analysed to compare with the difficulties in obtaining the certification. According to the results of the study, the GBCC requires additional amendments about the assessment categories of the energy consumption monitoring and the building commissioning as required subjects in order to secure the building performances. In addition, the operation mamagement of the building need to be assessed more intensively.

Weather factors affect cost increases and progress management under construction. Because progress schedule is delayed by weather factors, the construction costs are increased. It is an essential element to control the progress schedule applying weather factors to the progress management. This study applies monthly working-day percentages which is estimated by databases of past weather information to RTPM system. Through do progress management in construction projects exactly, will try to minimize risk of process control that do that is to weather factors. Also, will compare calamity in safety supervision side that do that is to weather factors beforehand. Based on the factors and the expected impact of factors together with the weather data during the last 50 years in Seoul region gathered from Korea. Through it, calculated number of month working day of RCA's structural steel work. Studied way that apply to RTPM system.

A Conceptual cost estimate, which is computed in the preliminary step of a project, is important for decision-making by a contractor in terms of the project budget, economic feasibility and validity analysis, and alternative comparisons. Therefore, a high error rate of a prediction model for a conceptual cost estimate can lead to various problems including excessive project expenditures and a delayed break-even point. this study proposed optimal impact factors by configuring quantitative impact factors computable in a preliminary step in various cases(combinations of impact factors). subsequently, the accuracy of different cases was comparatively analyzed by using the cases as input values of a prediction model using regression analysis. when the optimal combination of impact factors proposed in this study and other combination of impact factors were applied to the prediction model, the regression analysis-based prediction model exhibited 0.2-4.7% improvements in accuracy, respectively. the optimal combination of impact factors proposed in this study improved the accuracy of the prediction model of a conceptual cost estimate by removing unnecessary impact factor.

The proportion of buildings over 30 years old in Korea has increased, from 29.0% in 2005 to 37.8% in 2019. These old buildings were built during a time in which there was a lack of building-related safety standards in areas such as fire safety performance. Worse, during their years of use, many such old buildings have had illegal changes and extensions made, making them more vulnerable in terms of safety. Fire safety investigations are being conducted to prevent large-scale disasters in multi-use buildings, but no investigation has been conducted at the regional district level, where small-scale old buildings are concentrated. Therefore, to identify fire risk factors in the old building district where old buildings are concentrated, the composition characteristics of the buildings were first analyzed. To examine the spatial characteristics of old building districts in order to derive fire risk factors, the results of this analysis based on the structure, use, roof type, and year of approval for use are as follows. It was found through our analysis that as of the date of approval for the use of the building, the main structure of the building has the greatest impact.
