Objective: The aim of this study is to identify the domestic and foreign laboratory safety management system and to suggest domestic laboratory safety management policy priority. Background: Various types of accidents are occurred in research laboratories according to a variety of laboratory safety risks. However, there are only lists of incidents without any precise accident analysis. Method: We analyzed statistically the survey on current status of laboratory safety management of universities, research institutes, and industrial research institutions carried out by Ministry of Science, ICT and Future Planning in Korea. We also investigated laboratory safety management systems and safety organization carried out mainly in overseas countries such as USA, Japan, Switzerland and France. In addition, we analyze the UCLA College laboratory explosion occurred in the US in 2010. Results: More than 75 percent of 2015 domestic laboratory accidents were occurred in the field of operation management and chemistry research. Also, approximately 55% of accidents took place due to careless use mechanical instruments & dangerous chemicals. In addition, common difficulties of lab safety act applicable organizations are overlapping and comprehensive application of legal requirements. Conclusion: There is a need for laboratory safety professional organizations. Also, the high frequency of use of hazardous substances in the high-risk, such as the chemical field must be strengthened the laboratory safety management. In addition, it is needed to minimize the problems of the research organizations through close cooperation between related ministries and government support policy such as professional development program. Application: The result of this analysis might help to present a differentiated safety management policy and advanced safety management system in laboratory.

The legal basis for the systematic prevention and response to landslide hazards, and the rehabilitation of landslide-hit areas, was established through the amendment of the Forest Protection Act in August 2012. The most noticeable amendment to the Act is the inclusion of clauses associated with the designation and management of landslide-prone zones (including debris flow-prone zones). In this paper, we (1) introduce the clauses related to the designation and management of landslide-prone zones that were included in the amended Forest Protection Act, (2) examine their significance by reviewing the present status of related domestic laws and structural countermeasures such as sediment check dams for sediment-related disaster prevention, and (3) suggest the future directions of the procedure for the designation and cancellation of such zones, and their maintenance and institutional aspects. The establishment of an institutional device for the designation and management of landslide-prone zones has great significance in the aspect of (1) the establishment of a comprehensive management and prevention system for potential landslide-prone zones in forested areas where the hazard risk has been poorly recognized as compared with the flood risks in lowlands, and (2) the establishment of the basis for overcoming the limits of structural countermeasures according to limited budgets. To develop the designation and management system for landslide-prone zones, not only must present problems be addressed, but a cooperation system between the administration and local residents must also be established.

This study aimed to identify the effects of fashion brand extensions types, preannouncing and consumers' regulatory focus on preference towards extension products. To that end, the study used a 2 (fashion brand extension types: similar vs. non-similar) ${\times}2$ (preannouncing: near preannouncing vs. far preannouncing) ${\times}2$ (regulatory focus: promotion focus vs. prevention focus) three mixed elements. The subjects of the study were 280 men and women in their 20~40s living in Seoul and Chungnam province and total of 229 data were analyzed. Data were analysed with SPSS 19.0 program and three-way ANOVA, simple interaction effects and simple main effects analysis were conducted. The results of this study are as follows: First there were significant differences in preference based on fashion brand extension types and preannouncing. Second, there were significant interaction effects in preference between extension types of fashion brand and regulatory focus. But there was no difference in preference toward extension products according to types of preannouncing and regulatory focus. Lastly, fashion brand extension types, preannouncing and regulatory focus showed significant interaction effects on preference. Thus even in cases of non-similar brand extensions which carry more risk of failing, the appropriate marketing communication strategies such as preannouncing will result in brand preference. Also marketing activities should be comprehensive and strategical based on consumers' tendencies in order to derive positive evaluations.

Purpose: The purpose of the present study was to assess the incidence of the potentially inappropriate medication (PIM) use in Korean elderly patients with heart failure, and to evaluate factors that influence PIM use. Method: Korean National Health Insurance claims database between January 2009 and December 2009 was used. Using 2012 updated Beers criteria, PIM use in heart failure patients aged 65 years or older was examined. Result: The incidence of PIM use in elderly heart failure patients was higher than in overall elderly patients. Among the 12,759 elderly patients with heart failure, 46.2% of study subjects were prescribed PIM(s) at least once. The number of PIM per 10 medications that patients received per patient was 1.53. The most commonly used PIMs in elderly heart failure patients were benzodiazepines (30.9%), non-steroidal anti-inflammatory drugs (NSAIDs) including COX-2 inhibitors (16.3%), digoxin (9.9%), and spironolactone (9.0%). Women (odds ratio, 1.20; 95% CI, 1.17-1.24), medical aid (odds ratio, 1.11; 95% CI, 1.08-1.13), and long-term facilities (odds ratio, 2.69; 95% CI, 2.44-2.96) were revealed to be important factors associated with PIM use. In addition, patient's age also seems to influence PIM use. Conclusion: Elderly heart failure patients are at a greater risk for adverse drug events attributed by inappropriate medication use. Efforts to increase awareness of PIM use in elderly heart failure patients are needed. In addition, various comprehensive strategies and policies to identify and prevent PIM use should be established nationwide.

Seismic safety analysis of rockfill dams are consist of the stability analysis as an simplifed method and the dynamic analysis as an detailed method. When high risk dams such as Multi-purpose dams were often applied detailed method by dynamic analysis, dynamic properties of dam materials such as shear modulus are considered as most important factor. Dynamic material properties such as shear modulus had to be investigated by cyclic triaxial test et al. during design and construction stage but these were not conducted because of the condition of domestic seismic design technique. MASW and SASW methods had been applied as a non destructive method to investigate dynamic material properties of existing rockfill dam, has no problems in dam safety at present. These methods were usually performed under the assumptions that the subsurface can be described horizontally homogeneous and isotropic layers. Recent studies(Marwin, 1993, Kim, 2001) showed that surface waves generated through inclined structures have different characteristics from those through a horizontally homogeneous layered model. further Kim et al(2005) and Min and Kim(2006) showed that central core type rockfill dam overestimated the shear wave velocities as increasing the depth through the 3D numerical modelling dut to the effect of outer rockfill and geometrical reasons In this study the results of shear wave velocities of seven rockfill dams form comprehensive facility review, was carried out from 2003 to 2007, were collected and analysed to establish the shear wave velocity distribution characteristics in increasing confining stress in rockfill dams and surface wave velocity ranges in rockfill dam through MASW and the limitation in application are discussed to be utilized as an reference value for dynamic analysis.

최근 전자금융사기에 대한 관심이 증가되고 있다. 특히, 전자금융사기는 사회공학적 양상으로 진화하고 있다. 이러한 높은 관심에도 불구하고 전자금융사기를 방지하기 위한 적절한 가이드라인은 거의 없는 실정이다. 더군다나, 실제피해자들을 대상으로 관련 연구가 거의 이루어지지 않고 있다. 본 연구의 목적은 실제 피해자들을 대상으로 왜 전자금융사기가 발생하는지에 대한 근원적 접근을 시도하고자 한다. 보다 실제적인 현실세계를 반영하기 위해, 본 연구에서는 피해자들을 대상으로 초점면접기법(FGI)을 활용해 분석하였다. 분석결과, 전자금융사기를 당하는 데에는 일정한 피해패턴이 있음을 발견할 수 있었다. 또한 왜 전자금융사기가 발생하는지에 대한 근본적인 물음에 대한 해답은 행동경제학에 바탕으로 둔 인간의 낙관적 편향이라는 심리적 인지오류로 인해 피해가 발생함을 확인할 수 있었다. 이 연구의 수행을 통해 위기관리 관점으로 향후 전자금융사기를 방지하기 위한 의미 있는 가이드라인과 방향성을 제공하며, 궁극적으로는 정부 및 산업계의 효과적 정책을 개발하기 위한 중요한 기초자료로서 활용되기를 기대한다.

Objectives : This study characterized the extent to which youth depressive symptoms, parental alcohol problems, and parental drinking account for differences in alcohol-related problems among a large sample of adolescent females. Methods : The stratified sample consists of 2077 adolescent females from twelve female-only high schools located in a large metropolitan city in the Republic of Korea. Students completed a questionnaire about alcohol use and alcohol problems, their parents' alcohol problems, and a number of risk and protective factors. Data were analyzed using tobit regression analyses to better characterize the associations among variables. Results : Almost two-thirds of students who consume alcohol had experienced at least one to two alcohol-related problems in their lives and 54.6% reported at least one current symptom of depression, with nearly one-third reporting two depressive symptoms. Two-thirds of the students indicated that at least one parent had an alcohol-related problem, and that approximately 29% had experienced several problems. Results of tobit regression analyses indicate that youth alcohol-related problems are positively associated with depressive symptoms (p<0.01) and parent drinking problems (p<0.05). Parental drinking is no longer significant when the variable parental attention is added to the model. Decomposition of the tobit parameters shows that for every unit of increase in depressive symptoms and in parent drinking problems, the probability of a youth experiencing alcohol problems increases by 6% and 1%, respectively. For every unit of increase in parental attention, the probability of youth experiencing drinking problems decreases by 5%. Conclusions : This study presents evidence that alcohol-related problems and depressive symptoms are highly prevalent among adolescent females. Although a comprehensive public health approach is needed to address drinking and mental health problems, different interventions are needed to target factors associated with initiation of alcohol problems and those associated with increased alcohol problems among those who already began experiencing such problems.

Objectives: This study was conducted to assess the potential health impacts and improve the quality of the free immunization program in Jinju City by maximizing the predicted positive health gains and minimizing the negative health risks. Methods: A steering committee was established in September 2010 to carry out the health impact assessment (HIA) and began the screening and scoping stages. In the appraisal stage, analysis of secondary data, a literature review, case studies, geographic information systems analysis, a questionnaire, and expert consultations were used. The results of the data collection and analyses were discussed during a workshop, after which recommendations were finalized in a written report. Results: Increased access to immunization, comprehensive services provided by physicians, the strengthened role of the public health center in increasing immunization rates and services, and the ripple effect to other neighboring communities were identified as potential positive impacts. On the other hand, the program might be inaccessible to rural regions with no private clinics where there are more at-risk children, vaccine management and quality control at the clinics may be poor, and vaccines may be misused. Recommendations to maximize health gains and minimize risks were separately developed for the public health center and private clinics. Conclusions: The HIA provided an opportunity for stakeholders to comprehensively overview the potential positive and negative impacts of the program before it was implemented. An HIA is a powerful tool that should be used when developing and implementing diverse health-related policies and programs in the community.
