  • Purpose: The study was designed to develop an instrument to measure risk factor-related deviant behavior (RFRDB) for the elderly. Methods: The preliminary instrument including 52 items to measure the risk factor-related deviant behavior for the elderly was developed through conceptual framework based literature review. The items were reviewed by experts to reveal the Content Validity Index (CVI). Then, construct validity and reliability were tested using factor analysis, comparative groups, and Cronbach's alpha with data from 233 elderly. Results: Among 52 items, 27 questions in the RFRDB instrument were selected from content validity and 21 questions in the final RFRDB were developed from testing validity and reliability. Results of empirical analysis(retest) of RFRDB were supported by 70% congruity with conceptual framework through literature review. The RFRDB has been completed by validity testing by known-group technique. The final developed RFRDB of the elderly has 21 questions each with a 4-point Likert Scale. Conclusion: The RFRDB may be utilized as a measurement to assess the risk of elderly deviant behavior.

  • In spite of lab safety act for over 10 years, over 100 safety accidents in the laboratory have been constantly occurring. The ideal safety management system is to prevent accidents by differential classifying and managing laboratory regulatory materials according to the risk level. In order to approach this system, in-depth interviews with safety managers were first conducted to identify the current status of safety management in domestic university laboratories. And then through comparative analysis of safety management systems in domestic and foreign laboratories, a new regulatory substance classification standard based on the analysis of the hazards and the classification of risk grades, and a safety management system are proposed. From this study, it will contribute to the creation of a safe laboratory environment by differential classification and management laboratory regulatory materials based on the risk level.

  • In this study, the earthquake risk assessment of single-story RC precast buildings in Turkey was carried out using loss curves. In this regard, Kocaeli, a seismically active city in the Marmara region, and this building class, which is preferred intensively, were considered. Quality and period parameters were defined based on structural and geometric properties. Depending on these parameters, nine main sub-classes were defined to represent the building stock in the region. First, considering the mean fragility curves and four different central damage ratio models, vulnerability curves for each sub-class were computed as a function of spectral acceleration. Then, probabilistic seismic hazard analyses were performed for stiff and soft soil conditions for different earthquake probabilities of exceedance in 50 years. In the last step, 90 loss curves were derived based on vulnerability and hazard results. Within the scope of the study, the comparative parametric evaluations for three different earthquake intensity levels showed that the structural damage ratio values for nine sub-classes changed significantly. In addition, the quality parameter was found to be more effective on a structure's damage state than the period parameter. It is evident that since loss curves allow direct loss ratio calculation for any hazard level without needing seismic hazard and damage analysis, they are considered essential tools in rapid earthquake risk estimation and mitigation initiatives.

  • Objective : Chronic subdural hematoma (CSDH) is a typical disease that is encountered frequently in neurosurgical practice. The medications which could cause coagulopathies were known as one of the risk factors of CSDH, such as anticoagulants (ACs) and antiplatelet agents (APs). Recently, the number of patients who are treated with ACs/APs is increasing, especially in the elderly population. With widespread use of these drugs, there is a need to study the changes in risk factors of CSDH patients. Methods : We retrospectively reviewed 290 CSDH patients who underwent surgery at our institute between 1996 and 2010. We classified them into three groups according to the time of presentation (Group A : the remote period group, 1996-2000, Group B : the past period group, 2001-2005, and Group C : the recent period group, 2006-2010). Also, we performed the comparative analysis of independent risk factors between three groups. Results : Among the 290 patients, Group A included 71 patients (24.5%), Group B included 98 patients (33.8%) and Group C included 121 patients (41.7%). Three patients (4.2%) in Group A had a history of receiving ACs/APs, 8 patients (8.2%) in Group B, and 19 patients (15.7%) in Group C. Other factors such as head trauma, alcoholism, epilepsy, previous neurosurgery and underlying disease having bleeding tendency were also evaluated. In ACs/APs related cause of CSDH in Group C, significantly less proportion of the patients are associated with trauma or alcohol compared to the non-medication group. Conclusion : In this study, the authors concluded that ACs/APs have more importance as a risk factor of CSDH in the recent period compared to the past. Therefore, doctors should prescribe these medications carefully balancing the potential risk and benefit.

  • We analyzed the terminology and classification related to the risk management of radiation treatment overseas to establish the terminology and classification system for Korea. This study investigated the terminology and classification for radiotherapy risk management through overseas research materials from related organizations and associations, including the IAEA, WHO, British group, EC, and AAPM. Overseas risk management commonly uses the terms "near miss", "incident", and "adverse event", classified according to the degree of severity. However, several organizations have ambiguous terminologies. They use the term "near miss" for events such as a near event, close call, and good catch; the term "incident" for an event; and the term "adverse event" for the likes of an accident and an event. In addition, different organizations use different classifications: a "near miss" is generally classified as "incident" in most cases but not classified as such in BIR et al. Confusion might also be caused by the disunity of the terminology and classification, and by the ambiguity of definitions. Patient safety management of medical institutions in Korea uses the terms "near miss", "adverse event", and "sentinel event", which it classifies into eight levels according to the severity of risk to the patient. Therefore, the terminology and classification for radiotherapy risk management based on the patient safety management of medical institutions in Korea will help in improving the safety and quality of radiotherapy.

  • 본 연구의 목적은 캄보디아와 베트남의 국가위험도와 영향요인들을 비교 분석하는 것이다. OECD와 한국수출입은행 모두 베트남보다는 캄보디아의 국가위험도를 더 높게 평가하고 있다. 국가위험도 분류에 따른 각각의 평가요소들에 대해 모수검정을 실시한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 지표 중 대외거래 지표들, 경제적 위험 중 외채 관련 지표가 두 국가 간의 국가위험도 차이에 통계적으로 유의한 영향을 미쳤다. 국가위험도 분류에 따른 평가요소별 모수검정 결과를 토대로 판별요인 분석을 통해 두 국가 간의 국가위험도를 가장 잘 나타내는 요인들을 추가로 추정한 결과, 정치 사회적 위험 지표인 부패지수, 경제적 위험 중 국내경제 지표인 경제성장률, 경제적 위험 중 외채 관련 지표인 외환보유액/월평균수입이 캄보디아와 베트남 간의 국가위험도 차이를 잘 대변하는 것으로 나타났다. 결론적으로 캄보디아가 국가위험도를 베트남 수준으로 낮추기 위해서는 무엇보다도 부패척결, 수출증대 등 대외거래 확대가 필요하다고 할 것이다. 베트남 또한 지속적인 경제성장 달성과 외환보유고 증대에 주력할 필요가 있을 것이다.

  • Taking into account the globalization of the economy and the intensification of European integration processes, it has been proved that an important part of evaluating the effectiveness of activity of public sector enterprises should be a comparative analysis of the overall operation environment, namely public procurement, economic environment and tax policy, with the relevant systems of other countries of the world. The indicators and components of international ratings "Doing Business", "Paying Taxes", "Benchmarking Public Procurement" have been studied. Different groups of indicators forming "Doing Business" and "Paying Taxes" in the context of the impact on public sector enterprises have been identified: those which fully comply with the need to evaluate the operating environment of public sector enterprises and those which should be used with restrictions, regarding the peculiarities of creating and functioning of public sector enterprises. A comparative analysis of the place of Ukraine, Lithuania and Slovenia among other countries of the world in accordance with the international rankings of "Doing Business", "Paying Taxes", "Benchmarking Public Procurement" have been made. It has been substantiated that the results of such comparative analysis will allow identifying risk areas, and relevant information can be used in developing of recommendations for improving the effectiveness of activity of public sector enterprises.

  • Even though social intervention in child abuse has begun in Korean society, there are many problems in terms of basic principles of child welfare services. Focusing on the principle of family preservation in child welfare services, this comparative study reviewed services for abused children and their families in the USA and Sweden. Results indicated directions for effective services for abused children are comprehensive and should be provided by community resources. Comprehensive services and follow-up of reported cases should be managed by public agencies and community networks. Education curricula for professionals and inter-disciplinary collaboration should be organized. A most important task in the future is to set up firm laws and policies for effective services in Korean society.
