This research aims to examine the impact of store personality and service quality on the customers' intention of revisiting the department store and their intention of recommendation to others. The participants were women in their 20s to 50s with experiences of purchasing apparel from major department stores. A total of 324 survey responses were used for the final analysis. The data were analyzed using factors analysis, reliability analysis, and multiple regression analysis with PASW 18.0. The results were as follows. First, the department store personality was composed of 3 factors; prestige, passion, sincerity. Service quality factors were defined as tangibility, responsiveness, and empathy. Second, the three dimensions of brand personality-prestige, passion and sincerity turned out to be influential factors affecting the customers' revisiting intention and recommendation intention. Also, tangibility and responsiveness of service quality factors had a significant influence on their revisiting intention, whereas tangibility, responsiveness and empathy factors had a significant influence on their recommendation intention. Third, the sub-dimensions of store personality and service quality had a different influence on the customers' revisiting intention and recommendation intention according to the department store brand.

This paper proposes a DEA model for the performance evaluation of each brand of coking coals in an integrated steel mill. The performance is defined as the efficiency which is the ratio of two linear combinations of the output factors to the input factors. There is only one input factor considered in the model : unit price of each brand based on CIF. Five output factors are chosen in consideration of their impact to the quality of cokes such as Ash, VM, LMF, TD, and Rm. Some of the output factors are treated as undesirable in DEA model because the quality criteria are given by the range. The CCR and BCC efficiencies are derived by the DEA model, and the scale efficiency is calculated, too. Each brand of coking coal is classified into four categories according to the CCR and BCC efficiencies, and the most inferior brands are identified as a result. The impact of the input and output factors to the efficiency is analyzed using a multiple regression, then the unit price is revealed as the most critical among them. Also, ANOVA results show that there exist efficiency differences among the coal types and the countries imported, respectively. Finally, the quantitative projection for the inefficient brands is performed if they are to be efficient. The result could be utilized in selecting the good or bad brands of coking coal based on the efficiency in an integrated steel mill. Also, this model will be used to assess the relative efficiency of a new brand of coking coal if it is a candidate to be imported.

교통사고의 원인은 도로, 차량들의 물리적 요인과 인적요인으로 분류하고 있다. 이중 차량과 관련해서는 수많은 신기술들이 개발되었고 또 개발 중에 있으며 인적요인에 관해서는 최근 국내에서도 중요한 연구들이 수행 중에 있으나 그 결과를 실용화하는데는 더 많은 시간이 필요할 것으로 보인다. 도로요인에 관한 그 동안의 연구가 국도 등에 집중되었기 때문에 오히려 도로의 위계상 최상위 위치에 있는 고속도로를 중심으로 한 연구가 미진한 것처럼 비쳐지는 것도 부정할 수 없는 사실이다. 미국은 도로 안전도 증진을 목표로 IHSDM(Interactive Highway Safety Design Module)이라는 통합설계모듈의 개발을 추진 중에 있으며, 국내에서도 기초적인 연구가 시작되었다. 이러한 평가모듈의 개발에 필수적인 것이 도로설계대안별로 교통안전도를 계량적으로 평가하는 모형의 개발이다. 본 연구에서는 먼저 교통사고의 원인이 되는 도로요인 중 특히 도로선형과 교통사고와의 관계를 밝혀내기 위해 도로선형의 변화(선형개량, 도로확장)가 비교적 적었던 호남고속도로를 대상으로 고속도로의 선형요소와 교통사고와의 미시적인 관계를 규명하였다. 이를 위해 대상도로를 직선부, 곡선부. 완화곡선부 등으로 1차 구분하였으며 이들 구간의 선형요소와 지난 5개년('96년∼'00년) 간의 교통사고 자료를 데이터베이스화하여 모형산정에 이용하였다. 또한 도로선형 요소 중 특히 교통사고와 관계가 큰 것으로 분석된 몇몇 요소들을 이용해 고속도로 선형조건별 안전도평가모형을 구축하였다.

Background : Public hospitals suffer worsening shortage of physicians and face great pressure of recruiting doctors. This study is aim to identify the factors associated with retention of physicians who are working in public hospitals. Methods : We conducted a cross-sectional and self-administered questionnaire survey in July, 2011. A total of 333 physicians responded from the 31 public hospitals. We analyzed the difference of job retention across the variables among doctors stratified as salaried and public health doctors. We used chi-square test and multiple logistic regression analysis. Results : To the salaried doctor, longer work period(OR=2.04 in 3rd quartile), professional autonomy(OR=2.69), and positive attitude toward public health(OR=2.39) affect to the higher job retention whereas complain of low income(OR=0.33) and complain of poor clinical environment(OR=0.26) affects to the lower job retention. To the public health doctors, community connections such as hometown(OR=6.27), spouse factors(OR=3.49), and positive attitude toward public health(OR=3.19) affect to the higher job retention. But longer work period(OR=0.17 in 3rd quartile) affects to the lower job retention. Conclusions : Associated factors of job retention vary across physician's status. Professional autonomy has major impact on the job retention to the salaried doctor. And familial factors as well as community relationship have greatest impact to the public health doctor. Positive attitude toward public health is associated with the higher job retention to the both of salaried and public health doctors.

In response to the recent decline in the school-age population, universities have made attracting foreign students a major policy task for universities. As a result, the number of foreign students increased rapidly in terms of quantity, but in terms of quality, the risk is inevitable. Accordingly, the government presented education and internationalization competency certification system indicators on the basis of which quality control of students was systematized. Based on the above certification system, this study focused on analyzing the multiple factors that are actually given to the academic adaptation (performance) of the 2200 students who entered a certain university. In addition, factors other than the certification system index were discovered to comprehensively track how they affect the academic performance of students studying abroad. The researcher found the multi-reciprocal model analysis showed that the difference between the learner and the moderator was significant, and whether or not they had the Korean proficiency test (TOPIK) was significant. It also said that it could have a direct impact on Chinese University Entrance Exams (高考) are significant. If a model that is very effective in selecting students is established by each university and used as an indicator through this study, it will serve as a basis for efficient selection of students.

It is well known that Multiple Input Multiple Output (MIMO) systems offer the promise of achieving very high spectrum efficiencies (many tens of bit/s/Hz) in a mobile environment. The gains in MIMO capacity are sensitive to the presence of spatial and temporal correlation introduced by the radio environment. In this paper, we examine how MIMO capacity is influenced by a number of factors e.g., a) temporal correlation b) various combinations of low/high spatial correlations at either end, c) combined spatial and temporal correlations. In all cases, we compare the channel capacity that would be achievable under independent fading. We investigate the behaviour of "capacity fades," examine how often the capacity experiences the fades, develop a method to determine level crossing rates and average fade durations and relate these to antenna numbers. We also evaluate the influence of channel correlation on the capacity autocorrelation and assess the fit of a Gaussian random process to the temporal capacity sequence. Finally we note that the particular spatial correlation structure of the MIMO channel is influenced by a large number of factors. For simplicity, it is desirable to use a single overall correlation measure which parameterizes the effect of correlation on capacity. We verify this single parameter concept by simulating a large number of different spatially correlated channels.

Purpose: This descriptive study attempted to identify the influence of internal marketing perception, empowerment, and job satisfaction on customer orientation of clinical nurses. Methods: The subjects were 411 nurses with over one year working experience in a university hospital, located in I-city. The data were collected from April 20 to 30, 2012. using a self-report questionnaire. The data were analyzed using hierarchical multiple regression with the SPSS/WIN 17.0 program. Results: There were significant differences in customer orientation depending on general characteristics(age, marital status, education, position, clinical experience, and department). Internal marketing perception, empowerment, and job satisfaction correlated with customer orientation. As the results of hierarchical multiple regression analysis for impact factors on nurses' customer orientation show, factors are the outpatient department in working places(${\beta}$=.10), education and training in internal marketing perception(${\beta}$=.12) and empowerment(${\beta}$=.44), which accounted for 31.1% of customer orientation. Conclusion: Therefore, nurse managers should identify the needs to perceive nurses as internal customers, and the internal marketing strategy should be performed to empower nurses. Also, it is needed to place nurses with high customer orientation at the outpatient department.
