  • Safety accident rate of small-medium construction site is high. because of lack of safety management system, lack of safety management capacity, lack of investment for safety, Owner's insufficient awareness about safety. In order to improve this, Currently in Occupational Safety and Health Act, Construction site of amounts more than 300 million won less than 120 billion (architectural),150 billion won(civil) mandatory subject to the technical guidance on construction accident prevention. Context of construction accident causes with construction accident rate relationship analysis and case analysis of technical guidance, through a survey of stakeholders in the technical guidance drawn the problems of the construction accident prevention technical guidance system and ways to improve on this.

  • This study was conducted in order to assist with infusing safety consciousness and resolving insensitivity towards safety for industrial accident in workers, managers and executives of chemical companies. Among many industrial accident prevention methods, Korea has been mostly taking an engineering approach of preventing industrial accidents by replacing old machines with risks of an accident and through new facilities and equipments. Through an attitude survey of workers in large scale chemical companies, this study wished to examine the fact that the biggest reason why the accident rate for the past 10 years has not decreased is because safety consciousness has not been established yet.

  • Structures, systems, and components (SSCs) important to safety of nuclear facilities shall be designed, fabricated, erected, and tested to quality standards commensurate with the importance of the safety functions. Although SSC classification guidelines for nuclear power plants have been well established and applied, those for research reactors have been only recently established by the International Atomic Energy Agency (IAEA). Korea has operated a pool-type research reactor (the High Flux Advanced Neutron Application Reactor) and has recently exported another pool-type reactor (Jordan Research and Training Reactor), which is being built in Jordan. Korea also has a plan to build one more pool-type reactor, the Kijang Research Reactor, in Kijang, Busan. The safety classification of SSCs for pool-type research reactors is proposed in this paper based on the IAEA methodology. The proposal recommends that the SSCs of pool-type research reactors be categorized and classified on basis of their safety functions and safety significance. Because the SSCs in pool-type research reactors are not the pressure-retaining components, codes and standards for design of the SSCs following the safety classification can be selected in a graded approach.

  • The object of this study is to understand the psychological factor of the worker on safety and recommend experimental factor of safety education program. The following are the methods of this study. We analyzed the statistical data from survey to workers(N=139) about the psychological factor on safely. The survey consisted of 34 questions about 4 factors like private external characteristic, psychological characteristic, characteristics on behavior, and experience and reason of disaster. As the result of the analysis of the multi regression model on the base of correlation of each of the major factors, psychological health, effort on practicing, and satisfaction on their life were the variables with high influence on the safety mind of workers. So, it is good safety strategy for effective working to maintain healthy life with optimistic minds, and try to practice actively as usual. After considering the result, for the development of safety education program for working, we have to consider psychological factors of our workers that influence their safety and try to improve the experimental education opportunity, and it will be effective.

  • In the construction industry, most safety related researches have been focused on the safety matters in construction job site while the safety issues regarding facility management have been received limited attention. Hence, this research aimed to uncover the problems of current safety management practices then suggest improvement plans. Through the questionnaire suey and analysis, following conclusions were drawn. Regarding the safety mindset, participation rate in safety prevention activities is average at most. Therefore, the extra attention and effort by property owners and managers are required. Examination of accidents indicated that 88% of them were stemmed from unsafe activities, 10% from unstable mentality and 2% from unavoidable natural disasters. Therefore, 90% of these accidents could be prevented by eliminating unsafe activities. In addition to the above findings, several other facts and suggestions are detailed.

  • Recently, the importance of analytical techniques related to food safety is emerging in the food industry due to changes in diet patterns, environmental changes, climate change and consumer's interest in food safety. In particular, food safety accidents in the food industry may cause economic losses such as media reports, product recalls, consumer distrust, and so on. Therefore, a systematic, proactive and comprehensive food safety management system is increasingly required to prevent food safety issues. Efforts to ensure the reliability of food safety are essential by introducing various analysis instruments such as LC, GC, ICP, LC/MS/MS, GC/MS/MS, ICP/MS, PCR, and RT-PCR. In addition, recent food safety analytical techniques used in food industry should be shifted paradigm by developing multi-component simultaneous analytical method, low cost with high efficient analytical method, and eco-friendly method.

  • The "Guidance Document for Bioequivalence Study" was revised for adding to bioequivalence studies of controlled-release products after meal(Korea Food & Drug Administration Notification #2008-22, 2008.5.7). The bioequivalence study design for controlled-release products is $2{\times}2$ crossover under fast and fed condition in respect. For studies of controlled-release products under fed study, the same high-fat diet should be taken within 20 minutes in at least a 10-hour fasting state. The drug products should be administered 30 minutes after the meal started. A high-fat(more than 35 percent of total caloric content of the meal) and high-calorie(over 900 calories) meal is recommended as a test meal for fed BE studies.

  • 연구목적 :본 연구는 노인들이 인지하는 거주환경의 물리적 안전과 노인들의 계속 거주 의향과의 관계에 대한 분석을 목적으로 한다. 연구방법 : 연구를 위해 도시공간의 물리적 안전은 옥외공간과 건물의 안전, 보행안전, 교통안전 및 주거안전의 4가지 요소로 구분하였으며 계속거주의향에 대해서는 5점 리커트 척도로 구성하여 서울시거주 65세 이상 노인 411명을 대상으로 서울시 5개 권역별로 설문조사를 실시하였다. 연구결과 : 분석결과 응답자의 78.6%가 현 지역에서의 계속거주에 좋다고 응답하여 서울의 노인들은 에이징 인 플레이스(Aging in Place)의 경향이 강하다는 것을 알 수 있었으며 서울시 권역별로는 동남생활권, 서북생활권, 서남생활권, 동북생활권, 도심생활권 순으로 계속 거주가 좋다고 응답하였다. 결론 :현재 사는 지역에서 계속 거주하는 것에 대해 좋다고 응답한 비율이 높은 경우, 도시공간의 물리적 안전 전반 뿐 아니라 물리적 안전 요소들의 평균도 높아 물리적 안전이 현 지역에 계속 살고자 하는데 영향을 끼치는 요인이라는 것을 확인할 수 있었다. 연구 결과를 바탕으로 차후 신도시 조성 혹은 도시 재생의 과정에서 안전한 도시를 조성하는 방안의 일환으로 적용될 수 있을 것이다.

  • Purpose: To evaluate the long-term safety of polyethylene glycol (PEG) 4000 in children with constipation, particularly the biochemical aspects of safety. Methods: Medical records were evaluated, and 100 children, who had been taking PEG 4000 for more than 6 months, and who had been under clinical and biochemical monitoring, were enrolled. Ages; $6.11{\pm}3.12$ years, Duration of therapy; $16.93{\pm}7.02$ months, dose of PEG 4000; $0.72{\pm}0.21g/kg/d$. Results: None of the children complained of clinical adverse effect. The first biochemical test was performed at 8.05 months after beginning of PEG 4000. Serum phosphate (SP) value was high in 10 children, and leucopenia was noted in one child. The second test was performed in 44 children at 7.57 months after the first test. The SP value was high in four children, including the three children whose initial SP value was high and one new child. Six out of 10 children with high initial SP value became normal and one was lost. Hypernatremia was noted in one child. The third test was done in 15 children at 7.5 months after the second test. The SP value of the new child from the second test was high, but became normal after finishing treatment. Two out of 3 children with high SP value at the second test became normal and one was lost. The fourth test was done in 2 children few months after the third test. All of the results were normal. There were no relation between duration of therapy and hyperphosphatemia, or between dose of PEG 4000 and hyperphosphatemia. Conclusions: PEG 4000 is safe for long-term therapy in children with constipation with respect to biochemical parameters.
