  • Background/Aims: The Republic of Korea is a country where the hemodialysis population is growing rapidly. It is believed that the numbers of treatments related to vascular access-related complications are also increasing. This study investigated the current status of treatment and medical expenses for vascular access in Korean patients on hemodialysis. Methods: This was a descriptive observational study. We inspected the insurance claims of patients with chronic kidney disease who underwent hemodialysis between January 2008 and December 2016. We calculated descriptive statistics of the frequencies and medical expenses of procedures for vascular access. Results: The national medical expenses for access-related treatment were 7.12 billion KRW (equivalent to 6.36 million USD) in 2008, and these expenses increased to 42.12 billion KRW (equivalent to 37.67 million USD) in 2016. The population of hemodialysis patients, the annual frequency of access-related procedures, and the total medical cost for access-related procedures increased by 1.6-, 2.6-, and 5.9-fold, respectively, over the past 9 years. The frequency and costs of access care increased as the number of patients on hemodialysis increased. The increase in vascular access-related costs has largely been driven by increased numbers of percutaneous angioplasty. Conclusions: The increasing proportion of medical costs for percutaneous angioplasty represents a challenge in the management of end-stage renal disease in Korea. It is essential to identify the clinical and physiological aspects as well as anatomical abnormalities before planning angioplasty. A timely surgical correction could be a viable option to control the rapid growth of access-related medical expenses.

  • 신중년은 노동시장에 재진입하는 것으로 중요한 의미를 가진다. 무엇보다 재취업은 자신의 삶에 새로운 자신감을 갖게 되고 정신건강을 향상하는 계기가 될 것이다. 또한 정부는 신중년 자본의 활용을 통해 재정 부담을 감소할 수 있는 장점이 있을 것이다. 이런 시각에서 본 연구는 신중년의 긍정심리자본이 재취업의지에 어떠한 영향관계가 있는지를 탐색하고자 설계되었다. 이를 위해, 본 연구는 의정부시에 거주하고 있는 신중년 은퇴시기를 전후한 성인남녀를 270명을 대상으로 설문조사를 실시하였다. 설문을 분석한 결과 다음과 같다. (1)신중년의 교육수준은 재취업의지에 통계적으로 유의미한 긍정적 관계가 있었다. 이런 관점에서 신중년의 재취업을 활성화하기 위해 신중년에게 적합한 직종의 개발과 더불어 교육훈련프로그램을 체계적으로 운영할 필요가 있다. (2)신중년의 긍정심리자본은 재취업의지에 긍정적 영향을 미치는 것으로 나타났다. 신중년의 재취업을 고양하기 위해서는 자신에 대한 자신감, 구직관련 정보를 획득하기 위한 적극적인 자세, 사회적 네트워크를 활성화하려는 자세가 매우 중요하다.

  • As a large city advanced, the urban environment is becoming an issue. The contribution of vehicle emissions in air pollutants was very high according to the clean air policy support system (CAPSS). In order to improve the air quality in large cities, it is necessary to establish improvement measures by sources, analyzing the air quality of roadside. We divided Bucheon city into 4 regions to investigate the roadside pollutants of each district using the mobile laboratory (ML) and air quality monitoring station (AQMS). ML was used to measure pollutants emitted from vehicles and AQMS data was used as a comparison group of ML data. As a measurement result of pollutants in the roadside, the concentration of air pollutants in industrial & engineering complex area was the highest and concentration of air pollutants in residential & forest complex area was lower. By street, Bucheon-ro, Sinheung-ro, Sosa-ro, and Gyeongin-ro were identified as high concentrations. Therefore, further researches on preparing management measures for roads in the hot-spot area are needed.

  • 일반적으로 수소의 정제는 화학적, 물리적인 방법을 통해 수행한다. 여러 종류의 정제방법 중 현재는 정제 용량 및 경제성이 가장 우수한 PSA(Pressure Swing Adsorption)를 이용한 정제방법이 가장 널리 사용되고 있다. 국내도 대부분 PSA를 이용하여 자동차 및 발전용 수소 연료전지 등에 사용하는 수소를 정제하고 있다. 기존 석유화학 단지중심의 부생수소는 운송 등의 어려움이 있다. 정부는 도시가스 공급망과 연계하여 소비지에서 직접 수소를 생산하는 수소추출기 설치 계획하고 있으며, 기업들도 이와 관련된 연구 및 실증 설비를 속속 설치하고 있는 실정이다. 유럽 등은 최근 PSA와 관련된 안전기준을 마련하여 시공 및 운영단계에서 체계적인 안전관리를 위한 노력을 기울이고 있으나, 국내는 PSA와 관련된 안전기준 마련이 아직까지는 미흡하다. 본 연구에서는 기존 PSA를 운영하고 있는 회사의 설문 및 위험성평가를 통해 기존설비의 문제점을 파악하고, 국외 기술기준에 이를 포함한 국내 기술기준을 작성하여 신규설치 및 기존 운영되고 있는 PSA시스템의 안전을 도모하고자 한다.

  • The purpose of this study is to make an empirical analysis on the factors affecting the intention for the continuous use of the BSC system, which has been recently spread in the public sector. Because the object of acceptance is the performance management system based on BSC (Balanced Scorecard) implemented in the form of information systems, this study proposes a research model by applying TAM (Technology Acceptance Model). Independent variables are factors affecting the acceptance of BSC system such as training, communication, IS support, CEO support and personal innovativeness, and we examine their effects on the dependent variable, namely, intention on continuous use via mediating variables: perceived usefulness and perceived ease of use. A questionnaire survey was conducted with public institutions(firms) that had introduced and were operating the BSC system; 264 valid questionnaires are adopted. Collected data are analyzed using SPSS 16.0 and AMOS 7.0. Results of reliability test show that all analyzed data are reliable. In validity test, one item regarding communication was excluded; 9 latent variables and 34 observed variables are used in the final analysis. Based on the results of the hypothesis test through path analysis using a structural equation model, 10 out of 16 hypotheses are accepted. Factors affecting perceived usefulness are training and IS(Information System) support. The analysis results indicate that perceived ease of use is mainly affected by IS support, CEO support, and personal innovativeness among the factors related to the acceptance of the BSC system. This suggests that, contrary to the expectation that the BSC system may be used without difficulty, the management's active support is required in order to attain expected improvement in productivity and work efficiency. This was also pointed out in case studies on the construction of the BSC system in public sectors. On the other hand, perceived ease of use is found to affect perceived usefulness. This supports the results of previous researches on TAM. Perceived ease of use and perceived usefulness are found to affect the attitude towards the use of the system. The intention on continuous use is affected more by perceived usefulness than by the attitude towards the use of system. This result supports the results of previous researches on TAM, showing that the BSC system is utilized substantially in worksites. This study is considered meaningful in that it was actually performed on users at public institutions(firms) that had introduced the BSC system and that it empirically tested hypotheses on the acceptance of the BSC system by applying TAM to the research model.

  • 정부와 안전보건공단의 재해 절감을 위한 다양한 노력덕분에 산업과 건설업 전반에 걸쳐 재해 사고는 감소추세를 보이고 있다. 하지만 건설업에서의 추락재해는 감소하지 않고 오히려 증가하고 있다. 특히, 달비계에 의한 추락재해는 매년 발생빈도는 낮지만 발생 시 작업자의 사망과 직결한다는 측면에서 재해강도가 매우 크다고 할 수 있다. 국내 건설업에서의 달비계 작업환경은 매우 열악하다. 특히 소규모 건설현장에서의 달비계 작업자들은 안전에 대한 감독과 관리를 받을 수 있는 주체가 없다. 달비계 작업자들은 자신들이 직접 제작한 성능이 확인되지 않은 달비계를 가지고 불안전한 작업환경에 내몰리고 있다. 따라서 본 연구는 15년간 달비계에서 기인한 242건의 사고사례들을 분석하여 추락재해 발생 주요 원인 및 개선방안을 제시하였으며, 주요내용은 불안전한 행동에 의한 재해발생률이 높아서 작업대 안착 시, 안전난간을 넘어가는 과정, 몸의 불균형 등에서 사고가 많으며 설비개선 및 작업방법개선으로 해결이 요구된다. 또한, KOSHA Guide에서 제시하는 작업순서 상의 문제점으로 발생되는 재해는 없었으며, 다만 작업 순서를 따르지 않아 안전대를 안전대 걸이용 로프에 미설치 및 미부착에 의한 사망으로 이르는 재해가 다수 발생된 것으로 파악되어 작업방법의 개선에서 가장 중요한 사항은 수직구명줄 및 안전대의 설치 및 착용이 가장 중요한 사항으로 도출되었다.

  • Objectives: The characteristics of research workers are different from those working in the manufacturing industry. Furthermore, the reagents used change according to the research due to the characteristics of the laboratory, and the amounts used vary. In addition, since the working time changes almost every day, it is difficult to adjust the time according to exposure standards. There are also difficulties in setting standards as in the manufacturing industry since laboratory environments and the types of experiments performed are all different. For these reasons, the measurement of the working environment of research workers is not realistically carried out within the legal framework, there is a concern that the accuracy of measurement results may be degraded, and there are difficulties in securing data. The exposure evaluation based on an eight-hour time-weighted average used for measuring the working environment to be studied in this study may not be appropriate, but it was judged and consequently applied as the most suitable method among the recognized test methods. Methods: The investigation of the use of chemical substances in the research laboratory, which is the subject of this study, was conducted in the order of carrying out work environment measurement, sample analysis, and result analysis. In the case of the use of chemical substances, after organizing the substances to be measured in the working environment, the research workers were asked to write down the status, frequency, and period of use. Work environment measurement and sample analysis were conducted by a recognized test method, and the results were compared with the exposure standards (TWA: time weighted average value) for chemical substances and physical factors. Results: For the substances subject to work environment measurement, the department of chemical engineering was the most exposed, followed by the department of chemistry. This can lead to exposure to a variety of chemicals in departmental laboratories that primarily deal with chemicals, including acetone, hydrogen peroxide, nitric acid, sodium hydroxide, and normal hexane. Hydrogen chloride was measured higher than the average level of domestic work environment measurements. This can suggest that researchers in research activities should also be managed within the work environment measurement system. As a result of a comparison between the professional science and technology service industry and the education service industry, which are the most similar business types to university research laboratories among the domestic work environment measurements provided by the Korea Safety and Health Agency, acetone, dichloromethane, hydrogen peroxide, sodium hydroxide, nitric acid, normal hexane, and hydrogen chloride are items that appear higher than the average level. This can also be expressed as a basis for supporting management within the work environment measurement system. Conclusions: In the case of research activity workers' work environment measurement and management, specific details can be presented as follows. When changing projects and research, work environment measurement is carried out, and work environment measurement targets and methods are determined by the measurement and analysis method determined by the Ministry of Employment and Labor. The measurement results and exposure standards apply exposure standards for chemical substances and physical factors by the Ministry of Employment and Labor. Implementation costs include safety management expenses and submission of improvement plans when exposure standards are exceeded. The results of this study were presented only for the measurement of the working environment among the minimum health management measures for research workers, but it is necessary to prepare a system to improve the level of safety and health.
