This paper aims to empirically analyze the factors of difference in trust level for Internet-only bank by age groups. The purpose of this study is to provide clues and a research data in developing differentiation strategies that can increase consumer's trust by age group. In this study, above all, the financial consumer group was divided into the 2030s and 4050s based on age. The study explored the trust determinants of the two groups and compared the differences between the two groups using a multi-group analysis method. As results, in all age groups, financial consumer's trust was seen as a determinant of convenience, security and benefit of financial transaction costs. The difference of the determinant of trust between 2030s and 4050s occurred in the factor of benefit. Moreover, it reconfirmed that consumer's trust is later strongly extended to relationship commitment. These findings suggest that trust is of paramount importance to the Internet-only bank, whose market competition will intensify in the future.

Risk management should be controlled systematically by effectively evaluating and suggesting countermeasures against the various risks which are followed by the change of the society and environment. These days, enterprise risk management became a new trend in the field. The first step in risk analysis is to recognize the risk factors, that is to verify the vulnerabilities of loss in the security facilities. The second step is to consider the probability of loss in assessing the risk factors. And the third step is to evaluate the criticality of loss. The security manager will determine the assessment grades and then the risk levels of each risk factor, on the basis of the result of risk analysis which includes the assessment of vulnerability, the provability of loss and the criticality. It is of great importance to put the result of risk analysis in mathematical statement for a scientific approach to risk management. Using the risk levels gained from the risk analysis, the security manager can develop a comprehensive and supplementary security plan. In planning the risk management measures to prepare against and minimize the loss, insurance is one of the best loss-prevention programs. However, insurance in and of itself is no longer able to meet the security challenges faced by major corporations. The security manager have to consider the cost-effectiveness, to suggest the productive risk management alternatives by using the security files which contains every information about the security matters. Also he/she have to reinforce the company regulations on security and safety, and to execute education repeatedly on security and risk management. Risk management makes the most efficient before-the-loss arrangement for and after-the-loss continuation of a business. So it is very much important to suggest a best cost-effective and realistic alternatives for optimizing risk management above all, and this function should by maintained and developed continuously and repeatedly.

최근 기후변화로 인한 기상재해 중 건조와 관련하여 인플루엔자, 호흡기질환 등과 같은 질병과 산불발생빈도의 증가로 인해 건강 및 재산상의 피해가 증가하고 있다. 특히, 한반도의 주택지역은 산림지역과 근접하여 산불 발생시 그 피해와 복구비용이 막대한 것으로 나타났다. 뿐만 아니라 향후 지구온난화가 가속화 될 경우 건조와 관련한 환자와 산불로 인한 피해가 증가할 것으로 예상되므로, 이에 대한 사전방재계획 및 복구계획 등이 필요하다. 이와 같은 건조현상 등의 자연재해에 대한 방재계획이 효과적으로 운영되기 위해서는 방재 정보를 인지하고 실천하는 개인의 적극적인 활용이 필요하다. 특히, 개인의 생활에 영향을 미치는 피해는 정부적인 대책보다 개인이 스스로 인지하여 대비함으로써 감소시킬 수 있기 때문에 재해에 대한 개인의 인지정도는 대책마련에 있어 중요한 요인이 된다. 이에 따라, 본 연구에서는 건조로 인한 질병 및 산불 발생 등 기상재해 증가에 대한 사전방재계획의 효과적인 운영을 위하여 설문조사분석을 통한 일반인의 건조특보 인지도 및 활용도 분석을 실시하였다. 또한, 기후가 변화함에 따라 더운 낮과 밤의 증가로 건조현상뿐만 아니라 폭염의 발생빈도도 증가할 것으로 예상되고 있다. 이와 관련하여 기후변화 적응측면에서 국민들의 건조특보 및 폭염특보와 관련한 정보 습득이 잘 이루어지고 있는지를 파악하고자 한다. 이를 위해, 선행연구에서 대학생의 주된 폭염특보 관련 정보습득경로가 TV와 인터넷인 점을 참고하여, 기상청에서 제공하는 건조특보와 폭염특보 발표일수와 TV, 인터넷의 대중매체를 통한 보도회수를 비교 분석하였다. 본 연구를 통해 대학생집단과, 10대, 20대의 저연령층의 인지도가 상대적으로 낮은 것으로 파악되었으며, 이는 대중 매체를 통한 건조특보와 관련한 정보전달의 부족으로 나타났다. 폭염특보와 관련한 언론보도는 기상전달뿐만 아니라, 폭염의 위험성, 폭염으로 인한 피해상황, 폭염특보제 홍보, 폭염과 관련한 대비책 등 다양한 내용으로 기재되었다. 반면에, 건조특보의 경우에는 대부분이 단순 기상전달로 폭염특보에 비해 보도의 다양성이 결여되어 있었다. 차후 대중매체를 통한 이용자들의 접근성을 증대시키기 위해서 신속하고 정확한 정보전달이 필요하다. 산불 및 화재예방과 관련하여 기상청의 정확한 기상정보 제공과 사전방재계획 수립에 대한 필요성을 직업별, 연령별로 구성된 각 집단의 50%이상이 느끼는 것으로 나타났다. 이에 따라, 기상정보 전달의 핵심인 기상청을 중심으로 온라인/오프라인 상의 기초교육부터 체계적인 사전방재계획 및 안전교육 프로그램 마련이 필요하다.

The object of this study is a development of a stochastic user equilibrium transit assignment algorithm for multiple user classes considering stochastic characteristics and heterogeneous attributes of passengers. The existing transit assignment algorithms have limits to attain realistic results because they assume a characteristic of passengers to be equal. Although one group with transit information and the other group without it have different trip patterns, the past studies could not explain the differences. For overcoming the problems, we use following methods. First, we apply a stochastic transit assignment model to obtain the difference of the perceived travel cost between passengers and apply a multiple user class assignment model to obtain the heterogeneous qualify of groups to get realistic results. Second, we assume that person trips have influence on the travel cost function in the development of model. Third, we use a C-logit model for solving IIA(independence of irrelevant alternatives) problems. According to repetition assigned trips and equivalent path cost have difference by each group and each path. The result comes close to stochastic user equilibrium and converging speed is very fast. The algorithm of this study is expected to make good use of evaluation tools in the transit policies by applying heterogeneous attributes and OD data.

The purpose of this study was to examine the recognition of citizens in Busan on the doctor-designation system, the awareness of medical consumers with experience of using this system and their satisfaction in an effort to seek ways of improving this system. The subjects in this study were the selected citizens in Busan who were at the age of 20 and up. As a result, it's found that the largest group of the respondents was female, in their 20s, received college or higher education, students and in the service industry, and that the most common monthly mean income was between two and 2.99 million won. 27.7 percent were aware of the doctor-designation system, and 23.7 percent became cognizant of the system through others who had used it. The rate of knowing the rules of the doctor-designation system (the right answer) stood at 66.3 percent. They got to know about the system through mass media(31.9%), and used it since it offered highly specialized treatment(57.5%). The respondents who had used it intended to reuse it(76.3%), and the reason was that they were provided with high-class medical services (35.2%). The respondents who had used this system got a mean of 2.96 in satisfaction level, which was not high in general. They mentioned more publicity efforts(91.2%), offering information in a conspicuous place (96.7%) and cutting doctor-designation treatment fee as a means of improving this system. As for how to ensure the operating efficiency of the system, sustained publicity seem to be necessary to raise awareness of the system among patients, and it's required to take measures to relieve patients of financial burden caused by medical bills.

Fluoride use is the best and widespread method for dental caries prevention. The aim of this study was to investigate experience and recognition of fluoride for caries prevention focusing on majors in one university. Four hundred twenty-four university students were selected by convenience sampling with informed consent and answered the questionnaire by self recording type. The subjects except dental hygiene students knew about purpose of fluoride use (84.6%), over the count fluoride rinse (63.2%), fluoride toothpaste (61.5%), professional fluoride application (56.4%) and water fluoridation (43.6%). They experienced over the count fluoride rinse (67.5%), school fluoride rinse (45.3%), professional fluoride application (30.8%), fluoride toothpaste (28.2%) and water fluoridation (12.0%). The main information paths about fluoride were university lectures among dental hygiene students and internet and mass media, followed by nurse-teachers among non dental hygiene students. The ratios of intention to use fluoride were: 67.8% in dental hygiene, 34.9% in health, 51.4% in non-health in case of professional fluoride application for oneself, 93.1% in dental hygiene, 48.0% in health, 50.4% in non-health in case of professional fluoride application for their children, 79.0% in dental hygiene, 51.3% in health, 55.8% in non-health in case of water fluoridation. The subjects to experience and recognize fluoride for caries prevention had more positive intention to use fluoride. The answers of students majoring in health or medical care were not different from non-health, except dental hygiene. Dental professionals should try to let the public know about fluoride use for caries prevention through mass media and internet as well as individual education in dental clinics.

The purposes of this study were to: a) provide evidence concerning the effects of emotional intelligence on job outcomes, b) examine the impacts of emotional intelligence on employee-related variables such as 'job satisfaction', 'organizational commitment', 'organizational performance', and 'turnover intention' c) identify the conceptual framework underlying emotional intelligence. A survey was conducted to collect data from foodservice managers (N=231). Statistical analyses were completed using SPSS Win (16.0) for descriptive analysis, reliability analysis, factor analysis, t-test, correlation analysis, cluster analysis and AMOS (16.0) for confirmatory factor analysis and structural equation modeling. The concept of emotional intelligence (EI) has been on the radar screens of many leaders and managers over the last several decades. The emotional intelligence is generally accepted to be a combination of emotional and interpersonal competencies that influence behavior, thinking and interaction with others. The main results of this study were as follows. The four EI (Emotional Intelligence) dimensions correlated significantly with age. The means of job satisfaction score were above the midpoint (3.04 point) scale. The organizational commitment score was above the midpoint (3.41 point) scale and was higher at 'loyalty' factor than 'commitment' factor. The means of organizational performance score were above the midpoint (3.34) scale. The correlations among the four EI (emotional intelligence) factors were significant with job satisfaction; organizational commitment, organizational performance and turnover intention. The test of hypothesis using structural equation modeling found that emotional intelligence produced positive effects on job attitude and job performance. Emotional intelligence enhanced organizational commitment, and in turn, managers' attitude produced positive effects on organizational performance; emotional intelligence also had a direct impact on organizational performance. This study has identified the effect of emotional intelligence on organizational performance and attitudes toward one's job.

In the benefits of ITS, there are intangible gains from real-time traffic information as well as classical gains such as travel time saving. These intangible gains are difficult to be estimated by existing transportation investment appraisal commonly used in SOC investment. The major reason is not because of the absence of methodology but because of the absence of generalized values of particular benefits from real time traffic information. This research explores the value of real-time traffic information on VMS that is the most representative of ITS services, by using CVM with Double Bounded Dichotomous Choice Question. Willingness-To-Pay (WTP) functions of drivers are built with survival functions using various types of probability distribution functions such as Exponential, Log-logistic, and Weibull functions. The results reveal that Log-logistic distribution is the most appropriate distribution model to estimate WTP, and the estimated coefficients are stable through LR (Likelihood Ratio) test. For the further study, it is recommended to perform statistical tests of temporal and spatial transferability that is not examined in this research due to the lack of data.

This study is related to determination of the intention to watch a movie, which is affected by various emotional, environmental, and behavioral factors. In case of personal factors, personal taste formed on the basis of previously experienced movie related information affects selection of movies, while environmental factors are affected mostly by residental community experience, cognitive attitude, subjective norms, as well as the view of values. In this study, the determinants on decision to watch movie have been analyzed applying the theory of planned behavior. Taking into consideration that the determination, based on either personal factors or environmental factors, of consuming movie products stars from reasonable information collecting and that movie poster has been the primary source of information on movie products since the inception of the movie industry, this study analyzed tastes of movie watchers and many variables of movie poster format on determination of intention to watch movie. The results from this empirical study indicate that movie poster is effective means of low cost marketing inducing movie watching in terms of consuming minimum time and space with high speed of delivery while satisfying primary interest on the movie product. It is suggested movie posters should be prepared to make appeal to each generation of target consumers and be put on the market as a product of artistic work.
