Lattice towers and tubular steel poles have been commonly used for electrical power transmission in Korea as well as the other countries. They are durable, structurally stable, simple and can easily be constructed in limited spaces. However, residents are opposed to construct transmission lattice towers in their areas because they are not visually attractive, and electrical field occur at the transmission lines. Underground transmissions have been used instead of the traditional towers to resolve these problems, however they are not cost effective to construct and run. Therefore, we have developed compact towers that are more attractive, well blend into the surrounding environment and much more economical than underground transmissions. This paper shows the design of a compact towers with insulation arm, in order to reduce the height of tower and the separation between phases. The compact tower can be installed in a narrow right-of-way. Insulation arms are easily applied to lattice and steel tubular towers instead of steel arms. Compact towers with insulation arm are also considered as a solution to have public acceptance or to create a familiar atmosphere among towers and people. Compact tower compared with a conventional tower, insulation arms reduces the width and height of the tower by 20% and 15% respectively.

Local public corporations are closely related to the welfare promotion of local residents because they are responsible for the management of public facilities and are entrusted with some of the duties of local governments. Besides these responsibilities, they also have to conduct systematic and professional record management to ensure the legitimacy and fairness of organizational activities as the importance of ethical management and knowledge management emerges in organization. With regard to this task, this study proposes an improvement plan for the records management of local public corporations by analyzing the current status of records management and the awareness level for the possibility of developments in record management work. For this endeavor, the study conducted a literature review, gathered 50 survey responses from archivists from local public corporations nationwide, and performed 18 interviews with the survey respondents. Based on the analysis of these data, the study proposes that the National Archives of Korea should strengthen the role of supporting local public corporations. Moreover, local public corporations are suggested to improve records management at the local level and form a cooperative union among similar corporations.

The purpose of this study is to explore the experiences and challenges of public guardianship services project for the mental disabled as a system of supporting the decision-making and the rights advocacy. For this purpose, interviews with 11 social workers who act as public guardians were conducted and a model of practice was suggested through analysis using the grounded theory of Strauss and Corbin(1998). As a results, the possibility of rights advocacy through public guardian services for the mentally disabled, the positive change of attitude of the facilities and the establishment of direction for the restoration of rights for the mentally disabled were derived. Public guardians experienced excessive empowerment of their guardians or difficulties in the process of their duties, but were also able to defend the rights of the mental disabled and support self-determination right. Through this study, expansion of budgets and expansion of beneficiaries for public guardianship services, establishment of infrastructure for integration in the community, set-up a support organization for public guardian services and Raising awareness of the mental disabled and public guardian services were suggested.

This study was planned to investigate employer's attitude about health management of workers in coal mine industry. The sample size was 38.3% (178 coal mine industries) of total 463 coal mine industries. The mailing survey was used to collecting data of coal mine industry and manager of coal mine industry. Distribution of attitude about health management of workers in coal mine industry, specifically necessity and availability of some items of health management and some apparatus of working environment, was skewed to positive attitude. While recognition of susceptability of coal workers' pneumoconiosis was low, that of seriousness of incidence of coal workers' pneumoconiosis was high.

This study was carried out to evaluate the renewable energy dissemination programs in Korea, using peer-review. Especially, we used the peer review method which was suggested to evaluate the renewable energy program in U.S. by EERE, DOE. Before we implemented the peer review, we modified this method suitable for evaluating the renewable energy dissemination programs in Korea by getting advice from expertise in renewable energy policy. From this procedure, we have verified six evaluation criteria as Quality, Productivity, Accomplishments, Relevance and Management. We interviewed renewable energy policy expertise and corporation to evaluate the programs against these criteria. The result shows that overall programs were performed more than average. In addition, both the policy expertise and corporation perceived that "oan Guarantee Program" and "ompulsory Installation of Renewable Energy Facility in Public building" fulfilled its role to a great extent. However, the respondents pointed out that all of the programs need to be improved on its management.

This study was planned in order to investigate coal miners' recognition and attitude toward pneumoconiosis, and its realtionship with related behavior for prevention of pneumoconiosis. Study object was coal miners in Kangneung area, sampled by multistage random proportional sampling. Sample size was 13% of total coal miners in Kangneung area. The results were devided into three parts: (1) descriptive results presented percent distribution, (2) reclassification of knowledge, experiences, and attitude by factor analysis, (3) prediction of health behavior for prevention of pneumoconiosis by discriminant analysis. Knowledge, experiences, and attitude toward pneumoconiosis were classified into nine factors. Knowledge about pneumoconiosis were broken down to two factors and attitude to four factors, and valence, perceived severity were classified into each one factor. According to demographic, socioeconomic characteristics, and factors of knowledge, experiences, attitude about pneumoconiosis, about 62% of behavior of wearing respiratory protector was correctly discriminated. And by the same methods, about 81% of behavior of hospital visit at respiratory symptoms; cough, sputum, chest pain etc. was discriminated correctly.

The concentrations of serum proteins fractions and their electrophoretical patterns were investigated in 135 patients with coal workers' pneumoconiosis who participated in confirmative examination for pneumoconiosis in December 1989. Their radiographical profusions were classified as 1/0 or more. Agarose film and phosphoric acid-sodium hydroxide buffer(pH 9.6) were used for electrophoresis. Concentration of each protein fractions and electrophoretical patterns seemd to be equivalent to reference values. Serum ${\alpha}_1$- and $\beta$-globulin concentrations, however, were significantly different (p<0.50) among categories of small opacity profusions and showed the lowest level in the group of category 1. Albumin concentratins decreased and ${\alpha}_2$- globulin concentrations increased significantly (p<0.05) in the group of complicated with pulmonary tuberculosis. $\gamma$-globulin concentrations were not varied by category of profusions nor by pulmonary tuberculosis complication.

Sixty-two medical records of patients with coal workers' pneumoconiosis who died in hospital as coal workers' pneumoconiosis were analysed for study of the relationship between forced expiratory volume in one second ($FEV_1$) and life expectancy in coal workers'pneumoconiosis. In the group who died of asphyxia from hemoptysis, life expectancy were well fitted with $FEV_1$(p<0.05). But others were not well fitted to simple linear regression equation. The prevalence of ECG sign of col pulmonale was more in the group of cardiorespiratory failure than asphyxia group. So, in the case of far advanced cor pulmonale, it was difficult to predict life expectancy by simple linear regression equation
