  • 우리나라는 비교적 지진의 안전지대라는 의식이 팽배하다. 따라서 지진이 발생할시의 대처 방안또한 미흡하다고 할 수 있다 그러나 해외의 사례를 살펴보면 지진에 대한 충분한 대비가 없다가 갑작스러운 재난으로 큰 피해를 입는 경우가 있다. 또한 우리나라의 지진 발생 사례를 조사해 본 결과 지진의 발발 횟수도 작지 않았다. 만약 이러한 지진이 서울과 같은 대도시에 일어난다면 그 피해는 매우 심각할 것이다. 그럼에도 불구하고 아직 우리나라는 지진에 대한 대책을 구체적으로 모색하는 것이 다른 나라에 비해 부족한 것이 현실이다. 본 연구에서는 지진에 대비해 GIS를 활용하여 다양한 요인으로 지진 위험도를 분석하였다. 지진 발생 시 위험 요인으로는 건물 도괴 위험도, 화재 위험도, 대피 위힘도 이렇게 세 가지 위험도에 대하여 분석하였으며 분석 방법은 다음과 같다. 먼저 지진에 의해 발생하는 건물 도괴, 화재, 대피의 어려움 등과 같은 대표적인 재해를 규정하였다. 다음으로 재해 위험 요소를 도출하기 위하여 토지이용 실태, 인구밀도, 건물유형, 도로구조 등을 정량화 하였고 이를 분석하여 위험도를 결정하였다. 또한 분석된 위험도를 기반으로 하여, 재해 발생의 최소화와 대비를 위한 개선 방안을 제시했으며, 활용의 예로 대피 시나리오를 구축하였다. 본 연구는 동대문구의 3개 동을 대상 지역으로 연구를 수행하였는데 향후 이러한 연구 방법을 활용하여 지역을 확대하며 지진에 대한 위험도를 사전에 도출한다면 지진이 발생하더라도 피해를 줄일 수 있으리라 기대된다.

  • Mobile technologies and services have become one of the inevitable parts of people's lives and mobile businesses have also been widespread. Popular mobile internet services through cell phones have made people in the financial industry consider that 'mobile' is promising. Nevertheless, there have been little studies of mobile services in the financial industry and most of the studies have been concentrated on internet services. The main purpose of this study is to investigate on the determinants of intention to use mobile banking. To achieve the goal, based on the theoretical backgrounds of the Technology Acceptance Model(TAM). Survey questionnaires were distributed via post & email to 500 users who have been experiences with cell phone and have an account. Out of 291 responded questionnaires, 275 data sets were available for statistical analysis with SPSS 10.1. Research hypotheses are analyzed by LISREL 8.30. Factor analysis identified seven external factors : (1) convenience, (2) cost, (3) unusefulness, (4) riskiness, (5) personal innovativeness (6) users' self-efficacy (7) experience of mobile services. Results of this study show that convenience, unusefulness, riskiness, personal innovativeness and experience of mobile services have significant effects on intention to use mobile banking . Much of the previous researches have dealt with service provider only and have focused on mobile internet. In this regard, when it comes to a viewpoint that regards the mobile banking sector as a new sector of mobile businesses. This study may provide a guideline to activate of mobile banking acceptance.

  • Purpose: This was a descriptive research study to examine the patient safety risk factors and the level of safety management of nurses in emergency service, hospitals and to analyze the relationship between the two factors. Method: Data for analysis were collected from 232 nurses in emergency service, hospitals in Busan and Gyeongnam from July 30 to September 7, 2013. Data were analyzed using descriptive statistics, t-test, one-way ANOVA, and Pearson correlation coefficients. Results: Therapeutic agents showed the highest risk level. The prevention of transfusion errors showed the highest performance. As the nurses were working in regional emergency medical centers and received education more than 7 sessions on patient safety, they readily recognized the riskiness of the safety risk factors. In addition, as the nurses were older than 40, married, having more education about safety and understood the incident report registration system well, they performed safety management better. There were significant correlations between perception of the patient safety risk factors and performance for safety management. Conclusion: Nurses in emergency service, hospitals should try to improve safety management to reduce the risk factors shown to be higher based on the results and ensure the patient safety.

  • To construct road spatial information database, it is the main object of this study that an analysis of road factors and furthermore this is used to the rescue activities in case of urban disasters. When urban disasters such as earthquake or explosion cause fire and collapses people of the affected region happen to evacuate. But only to manage roads and monitor traffic volume, the road data is designed and managed using digital topographic map so it is short that the design of road spatial data to prevent disasters. In this study, we tried to suggest the evaluative factors of evacuation to design database : road width, traffic volume, the fixed or movable obstacles installed, the surrounding environments that dominate the land-use planning, the uses, materials, structures, sizes, and densities of the buildings. Thus, these could provide fundamental data to determine the disasters management planning for evacuation and rescue activities, to evaluate the riskiness, and to draw up hazard information map.

  • Balance function is one of the joint factors to determine fall in risk theory. It helps to moderate the progression and riskiness of falls for detecting balance and fall risk factors. Nevertheless, the objective measures for balance function require expensive equipment with the assessment of any expertise. We establish the existence and uniqueness of a multi-order fractional differential equations based on ${\psi}$-Hilfer operator on time scales with balance function. This class describes the dynamic of time scales derivative. Our tool is based on the Schauder fixed point theorem. Here, sufficient conditions for Ulam-stability are given.

  • This article analyses the concept of medicine in the legal context. It is not easy to define the concept of medicine because medical practice has various dimensions and the situation in which the practice is performed has a broad variety. The duty of medical law is to build the boundary of protection in that the nature of medicine would not be distorted by the factors of social systems like industry or governmental authorities. Without understanding the various dimensions - especially the dimension of Humanities and Sociology - of the medicine it is not possible to draw the limit on the performance of medicine appropriately. Concerning the medical practice (especially in the context of the regulation of medical licence), the enacted law (Medical Act) defines the concept just for form's sake and it finally depends on the interpretation of the legal enforcement authorities. Moreover, between the judgments of the courts there exists no coherent principles for the regulation and the interpretation of the Medical Act depends often on the riskiness, the abstract concept, which finally leads the interpretation to depend on the subject of the practice. On the contrary, the development and scientific movement of the technology tends to tighten the range of the medical professionals of medical practice and the perspectives of the medicine. Medical act is actually oriented at the patient's understanding of him- or herself. The above-mentioned tendency of the interpretation and the legal policy could lead the medicine away from its nature.

  • Purpose: This study examined a comprehensive model for assessing the success probability of electric vehicle (EV) commercialization in the Korean market. The study identified three risks associated with successful commercialization which were technology, social, policy, environmental, and consumer risk. Research design, methodology: The assessment of the riskiness was represented by a Bayes belief network, where the probability of success at each stage is conditioned on the outcome of the preceding stage. Probability of success in each stage is either dependent on input (i.e., investment) or external factors (i.e., air quality). Initial input stages were defined as the levels of investment in product R&D, battery technology, production facilities and battery charging facilities. Results: Reasonable levels of investment were obtained by expert opinion from industry experts. Also, a survey was carried out with 78 experts consisting of automaker engineers, managers working at EV parts manufacturers, and automobile industry researchers in government think tanks to obtain the conditional probability distributions. Conclusion: The output of the model was the likelihood of success - expressed as the probability of market acceptance - that depended on the various input values. A model is a useful tool for understanding the EV industry as a whole and explaining the likely ramifications of different investment levels.

  • In 21st Century business world, services are carried out in multifaceted, competitive and rationality manner that are characterized by evolving many factors, which are often unpredictable. On-the-go banking is a product in financial sector. However, it faces serious pitfalls being it riskiness. Bank customers compete for time-saving options. On contrary, PCBs compete for marginalizing its operating costs for enhancing its revenues. On strategic tactics, PCBs targets city customers in multi-facets including offering incentives for enhanced usages of on-the-go banking. Influencing customer's intention, attitude and behavior in banking, PCBs also offers incentive under market system along with often informational asymmetry. However, it causes exploitation. In most cases customers don't read terms & conditions of services. They don't save contract-copy. These weaknesses cause abuses. Customer faces hidden charges, extra fees, account hacked. Addressing the issue, Voluntary Insurance Option is proposed where PCBs will introduce it as a product of bank-services. Transferring risk away from customer will benefit both PCBs and bank-customers. This product can attract new customers who were on the brink using digital banking but just felt it was too risky. This model can facilitate the parties involved for increasing usage of on-the-go banking-services while customers can maintain optimal utility of usages.
