While demands on private securities have been increase, expectations on the service quality as compensation for the investment expensive is also rising. However, private security services are in situations of not satisfying various customer's needs owing to insufficient special manpower, capital, and skills in spite of expected high-quality services toward customers. Therefore, this study aims to find out the causality between private security enterprises and relationship characteristics, purchasing behaviors of customers, and then searching for a marketing strategy that can provide best services to the enterprises that are confronting to limitless competitive systems by grasping customer's needs and necessities. For achieving this goal, the study objected to shop employees using private security enterprises after diving Cheonan City of South Chungcheong Province into South, East and East, West, and then collected 236 persons by using the convenience sampling. Regarding to research tools, this study used questionnaire having been recomposed based on previous researches home and abroad, and frequency analysis, reliability analysis, factor analysis, correlation analysis, and regression analysis were carried out data was treated by treatments by using SPSS version 18.0 statistic package for treating the data. Through above research methods and procedures, results could be gotten same as followings. First, correlations between private security enterprise's relationship characteristics and purchasing behaviors showed positive (+) relations, and the latter was increased as much as relationship characteristics were high. Second, as the result of analyzing correlations between private security enterprise's relationship characteristics and purchasing behaviors, reputation, physical features, and communication affected influences to word of mouth activities. Third, reputation and communication affected to repeated purchasing behaviors as the result of analyzing private security's relationship characteristics and repeat purchasing behaviors.

Objectives: REM sleep behavior disorder (RBD), characterized by excessive motor activity during REM sleep, is associated with loss of muscle atonia. In recent years, it has been reported that RBD has high co-morbidity with CNS disorders (especially, Parkinson's disease, dementia, multiple system atrophy, etc.). We aimed to assess differences in clinical and polysomnographic findings among RBD patients, depending on the presence or absence of central nervous system (CNS) disorders. Methods: The medical records and polysomnographic data of 81 patients who had been diagnosed as having RBD were reviewed. The patients were classified into two groups: associated RBD (aRBD, i.e., with a clinical history and/or brain MRI evidence of CNS disorder) and idiopathic RBD (iRBD, i.e., without a clinical history and/or brain MRI evidence of CNS disorder) groups. Twenty-one patients (25.9%) belonged to the aRBD group and 60 patients (74.1%) belonged to the iRBD group. The clinical characteristics and polysomnographic findings of the two groups were compared. Results: Periodic limb movement disorder (PLMD), i.e., PLMI (periodic limb movement index)>5, was observed more frequently in the aRBD group than in the iRBD group (p<0.001, Fisher's exact test). Also, obstructive sleep apnea syndrome (OSAS), i.e., RDI (respiratory disturbance index)>5, was found more frequently in the aRBD group (p=0.0042, Fisher's exact test). The percentages for slow wave sleep and sleep efficiency were significantly lower in the aRBD group than in the iRBD group. Conclusion: We found that 1 out of 4 RBD patients had associated CNS disorders, warranting more careful neurological evaluation and follow-up in this category of RBD. In this category of RBD patients, we also found more frequent PLMD and OSAS. These patients were also found to have lower slow wave sleep and sleep efficiency. In summary, RBD patients with associated CNS disorders suffer from more disturbed sleep than those without them.

We focused on the missing confirmation domain of the hasteful behavior. We tried to identify the variety of hasteful behavior and the effects of missing confirmation behavior domain of the hasteful behavior on driving behaviors. 388 drivers responded to Hasteful Behavior Questionnaire, Driver Behavior Questionnaire(DBQ), and Driving Experience Questions. Data which have missing values among them were removed, 374 data were analyzed. As a result of factor analysis, hasteful behavior consist of time pressure, uncomfortableness, isolation, boring condition, and expecting rewards, and the DBQ consist of violation, error, and lapse. The components of hasteful behavior was divided into the missing confirmation behavior and the need for achievement domain by the second factor analysis and difference verification of coefficient of correlation. The missing confirmation behavior domain of hasteful behavior had significant influence on error and lapse. The isolation of the missing confirmation behavior domain had a negative effect, and the uncomfortableness of the missing confirmation domain had a positive effect on violation. The time pressure had a negative effect, and the isolation and the uncomfortableness had a positive effect on error and lapse.

Speeding and drunken driving make drivers fail to detect hazards and cope with various driving situations. These behaviors also raise the possibility of being involved in traffic accidents and tend to increase the number of fatalities. The authors compared the driving behavior determinants of a rockless drivers group, consisting of individuals who have committed traffic accidents or offended regulations through drunken driving, with a normal drivers group. In the results, the reckless drivers group showed high scores of 'speeding' and 'drunken driving', and they also stated that they had more experiences of speeding, drunken driving and traffic accidents. In the path analysis study, it was found that the impacts of the rockless drivers group's 'risk sensitivity' and 'situational adaptability' on traffic accidents were stronger than those of normal drivers. This means 'risk sensitivity' and 'situational adaptability' can explain the origins of traffic accidents better in the reckless drivers group than accidents of the normal drivers group.

Although many theoretical studies have tried to explain the volatility in financial markets using models of herd behavior, there have been few empirical studies on dynamic herding due to the technical difficulty of detecting herd behavior with time-series data. Thus, this paper theoretically extends a continuous beliefs system belonging to an agent based economic model by introducing a term representing agents'mutual dependence into each agent's utility function and derives a SV(stochastic volatility)-type econometric model. From this model the time-varying herding parameters are efficiently estimated by a Markov chain Monte Carlo method. Using monthly data of KOSPI and DOW, this paper provides some empirical evidences for stronger herding in the Korean stock market than in the U.S. stock market, and further stronger herding after the global financial crisis than before it. More interesting finding is that time-varying herd behavior has weak autocorrelation and the global financial crisis may increase its volatility significantly.

The importance of coaching leadership has been highlighted to enhance creativity and competence of human resources in convergence environment. This paper was validated through a structural relationships model, the impact of coaching leadership on behavioral dimensions of organizational effectiveness by focusing on mediating role of job characteristics. Coaching leadership activities showed a significant positive effect on job characteristics and turnover intentions. Job characteristics appear to have a mediating effect on the relationship between coaching leadership and organizational effectiveness, especially the coaching leadership itself not necessarily to improve organizational citizenship behavior, can increase organizational citizenship behavior when formed into a positive awareness of the job characteristics of organizational members.

This study aims to propose safety culture design to ease to find out and control behavior characteristics of Korean seafarers. By empirical research of 377 Korean seafarers, the result revealed that significant characteristic of Korean seafarers was "affection to others" and custom of Confucianism affected Korean maritime society prevalently. But there were no significant differences between groups, such as rank, age, gender and sailing route with vessel type except educational background. Furthermore, this study concluded that positive reinforcement was more useful than negative reinforcement to promote safety operation of vessels. Regarding the vessel's safety management, the fact that means for vessel's safety management are linked only to the levels of educational background suggests that the efficiency of vessel's safety operation would be achieved by introducing suitable safety management system depending on the level of educational background.
