최근 교통사고 화재 자살 감염병 등 4대 분야는 최근 3년간(2012~2014) 평균 사망자수(26,292명) 대비 '18년까지 4,201명(16%) 감축을 목표로 하고 있다. 행정안전부의 지역안전지수 공개에 따라 지자체별 안전사고 사망자수 감축을 목표로 다양한 정책이 추진 중이다. 안전한 도시구축을 위한 안전 인프라 사업을 지자체별로 도출하고 있으나, 효율적인 사업 콘텐츠 마련에 어려움을 겪고 있다. 본 연구로 사업추진의 성공모델(Best Practice)을 창출할 수 있도록 안전 인프라 사업 콘텐츠를 도출하였다. 안전도시 구축의 전국확산을 위한 지역별 안전관리 대상지를 선정하고 효율적인 국가 및 지자체 예산 마련의 기초자료로 활용이 가능하다.

This survey paper explores the application of multimodal feedback in automated systems for motor learning. In this paper, we review the findings shown in recent studies in this field using rehabilitation and various motor training scenarios as context. We discuss popular feedback delivery and sensing mechanisms for motion capture and processing in terms of requirements, benefits, and limitations. The selection of modalities is presented via our having reviewed the best-practice approaches for each modality relative to motor task complexity with example implementations in recent work. We summarize the advantages and disadvantages of several approaches for integrating modalities in terms of fusion and frequency of feedback during motor tasks. Finally, we review the limitations of perceptual bandwidth and provide an evaluation of the information transfer for each modality.

최근 들어 컴퓨터화된 열차제어시스템의 사용이 증가함에 따라서 장치들의 고장이 대규모 인명피해나 경제적 손실과 직결되는 경우가 발생하고 있다. 따라서 열차제어시스템의 안전성 확보를 위한 절차를 수행하는 체계인 안전성 활동을 시스템의 수명주기 전반에 걸쳐 진행하여야 한다. 본 논문에서는 안전성 활동 중에서 위험도 분석 및 평가를 위한 방법에 대해 알아볼 것이며, 그 중에 최적화된 새로운 방식을 한 가지 제안하고자 한다. 정성적인 분석과 정량적인 분석의 특징을 혼합하여 절충한 제안하고자 하는 방식이 Best-Practice(BP) 위험도 분석 방식이다.

In this survey, we present a modified inverse moment estimation of parameters and its applications. We use a specific model to demonstrate its principle and how to apply this method in practice. The estimation of unknown parameters is considered. A necessary and sufficient condition for the existence and uniqueness of maximum-likelihood estimates of the parameters is obtained for the classical maximum likelihood estimation. Inverse moment and modified inverse moment estimators are proposed and their properties are studied. Monte Carlo simulations are conducted to compare the performances of these estimators. As far as the biases and mean squared errors are concerned, modified inverse moment estimator works the best in all cases considered for estimating the unknown parameters. Its performance is followed by inverse moment estimator and maximum likelihood estimator, especially for small sample sizes.

The use of complementary and alternative medicine (CAM) is currently widespread and appears to be growing. As an increasing proportion of the population turns to CAM therapies, whether singly or in combination with allopathic medicine, the need for quality research in this area is reinforced. Much of this research consists of clinical studies aim ed primarily at clinicians, yet challenges arising from poor methodological quality will occur w hen interpreting study findings and their implications. For clinicians to be effective consumers of the scientific literature, familiarization with the principles of evidence based medicine (EBM) is essential. The goal of this review is to introduce clinicians to the concept of critical appraisal of clinical studies and foster critical thinking when reading research articles in order to best evaluate and incorporate study findings into their daily practice.

A commitment to physical activity is necessary for personal health, and is a primary goal of physical activity practitioners. Effective practitioners rely on theory and research as a guide to best practices. Thus, sound theory, which is both practical and parsimonious, is a key to effective practice. The purpose of this paper is to review the literature in search of such a theory - one that applies to and explains commitment to physical activity in the form of sport and exercise for youths and adults. The Sport Commitment Model has been commonly used to study commitment to sport and has more recently been applied to the exercise context. In this paper, research using the Sport Commitment Model is reviewed relative to its utility in both the sport and exercise contexts. Through this process, the relevance of the Investment Model for study of physical activity commitment emerged, and a more parsimonious framework for studying of commitment to physical activity is suggested. Lastly, links between the models of commitment and individuals' participation motives in physical activity are suggested and practical implications forwarded.

This global case study pursues diversification and intensification for an application system of the national wind atlas which has been developed to support national strategy building and promotion of wind energy dissemination. We chose nine counties' national wind atlas and compared their map area, extraction height, temporal and spatial resolutions, download services, etc. to derive a best practice for the Korea wind atlas application system. Therefore, the web service content is designed to offer high-resolution height information of which covers wind turbine rotor sweeping area and time-series dataset which can be downloaded for further analysis by users. It is anticipated that the system and web service would contribute greatly to wind energy policy making, business and research sectors.

This paper analyzes the technical efficiencies of 40 Korean system integration firms using data envelopment analysis (DEA) and Malmquist productivity indices. Technical efficiencies on average had been decreased over the five year period and the efficiency difference between best practice firms and catch-up firms had been increased during this period, meaning that the industry structure has become matured and the possibilities for catch-up firms to be efficient are not remained so much. The differences in efficiency by the differences in ownership structures are statistically significant. It implies that the efficiencies of group-affiliated firms have come from benefits such as the captive market umbrellas, not from their own management competencies. In addition, the technical efficiency is highly correlated with captive market sales, information productivity, sales per employees, rates of value added, returns on invested capital, and EBITDA.

Nasotracheal intubation is an essential procedure during general anesthesia for dental treatment. Fiberoptic intubation is best accomplished by those who perform it as part of their daily practice. But nasal approach of fiberoptic intubation has some complications such as epistaxis and laryngeal injury. Especially, epistaxis is common and it make fiberoptic intubation because of limited view. When the epistaxis obstruct the field of vision we have to withdraw the fiberoptic bronchoscope and consider the other method for securing the airway. We succeeded in securing the airway of patient who had epistaxis during the fiberoptic nasotracheal intubation without withdrawing the fiberoptic bronchoscope. We used blind intubation guided by light source placed the tip of fiberoptic bronchscope applied to lightwand intubation.

Data Envelopment Analysis-Assurance Region(DEA-AR) model is used in this paper to investigate the efficiency and performance potential of Korean banks as they engage in activities that incur interest and non-interest expenses and produce income. DEA provides a measure of each bank's relation to the best-practice frontier for its competitors. This can provide a better quality-benchmark than using industry averages or a particular peer bank branches as the benchmark. The banks are classified into efficient and inefficient sets. Multiplier values for AR-inefficient banks with unique slacks indicate the potential for management to improve the bank's performance relative to its peers. DEA-AR that provide economically reasonable bounds for the multipliers lead to profitability potential, as distinct from efficiency, results.
