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.

This research, conducted over a three-year period starting from 2020, was a collaborative project between practitioners in the field of VE design and the Korea Expressway Corporation, aimed at innovating the design VE project to construct an intelligent ICT-based smart highway and enhancing highway driving performance and customer satisfaction. The research included R&D support for payment and management systems integrated with IOT technology, the application of the developed prototype at highway sites, and analysis of user performance evaluation. Based on the Innovation Work Roadmap of the Korea Expressway Corporation, the research process involved collaboration between a public participation group and an expert group, considering the technical feasibility of data-based ICT technology through the National Idea VE Contest. The final VE design results were implemented at the Seongnam tollgate site with budget support from relevant departments, followed by a satisfaction survey. It is expected that the continuous contributions to achieving an ESG society, such as the increase in the number of customers using the tolling zone equipped with smart upgrades, along with their satisfaction rate, and the reduction in carbon emissions and total settlement time of highway users, will be sustained.

지방공사·공단은 「공공기록물 관리에 관한 법률」과 「지방공기업법」에서 규정하는 공공기관이자 지방공기업이다. 지방공사·공단의 사업은 지방자치단체의 업무 일부를 위탁 받아 공공시설 및 공공시설물 관리 등을 담당하고 있기 때문에 무엇보다 책임 있는 행정 운영이 중요하다. 이러한 지방공사·공단의 특성과 함께 조직운영에 있어서 윤리경영과 지식경영의 중요성이 대두되고 있기 때문에 조직 활동의 정당성과 공정성을 확보하기 위한 수단으로서 체계적이고 전문적인 기록관리가 수행되어야 한다. 본 연구는 전국의 지방공사·공단을 대상으로 하여 기록관리 업무현황과 더불어 기록관리 업무발전 가능성에 대한 인식도를 파악하여 개선방안을 제안하는 것을 목적으로 하였다. 문헌연구와 함께 전국 지방공사·공단 중 50개 기관의 기록관리 담당자로부터 받은 설문조사 응답을 분석하였으며, 응답자 중 18명을 대상으로 인터뷰를 실시하였다. 분석결과를 바탕으로 국가기록원의 기록관리 업무지원 역할강화, 지방공사·공단 차원의 기록관리 업무개선, 유사기관 간 협력체 구성 및 활성화를 개선방안으로 제안하였다.

본 연구의 목적은 정신장애인의 공공후견서비스 사업이 당사자의 의사결정을 지원하고 권익옹호를 하는 제도로서 역할을 하고 있는지 그 경험과 과제를 탐구하는 것이다. 연구방법은 Strauss와 Corbin(1998)의 근거이론을 이용하여 공공 후견법인 후견업무 실무자 11명을 대상으로 전문가인터뷰를 실시하고, 과정분석과, 유형분석 등을 통해 실천모형을 제시하였다. 연구결과로는 정신장애인의 공공후견서비스를 통해, 후견의 권리옹호의 가능성과 시설의 긍정적인 태도변화 및 정신장애인의 권리회복을 위한 방향성 확립 등이 도출되었다. 공공후견법인 종사자들은 후견인에 대한 과도한 권한 부여나 업무 과정에서의 여러 어려움을 경험하지만 정신장애인들의 권리를 옹호하고 자기결정권을 지원할 수 있는 경험을 하였다. 본 연구를 통해 후견서비스의 필요성과 확대의 당위성을 제시하였다.

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.

By using Factor analysis on the variables relating to the subjective symptoms of total 56 workers, who have exposed to mixture of organic solvents at the musical instrument manufacturing plant, as experinmental group, and 70 workers, who worked in noisy working environment as control group, the study was performed. It was confirmed that the variables found in hematological figures, age specification, occupational history and physical examination have a influential factor on the subjective symptoms of both groups. It was explicated that the ratio of these to total Eigen Values showed 31.1 percent in experimental group and the control group revealed 37.7 percent.

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
