With the technical development of fourth industrial revolution, VR game market is rapidly expanding. Meanwhile, heavy user group means the group consisting of people consuming certain media or contents more than others, which is the core constituency of the media industry, and there have been only a few studies on them. This study identified the factors that influenced the continuous intention of use of VR game heavy users and figured out their characteristics by verifying the difference in variables with the light user group. According to the results, the heavy user group showed higher behaviors than the light user group in terms of personal innovation, presence, and continuous intention of use variables. In addition to this, it was found that personal innovation, perceived quality, and presence had a significant influence on the continuous intention of use. This study is intended to empirically analyze the characteristics of heavy VR game users and influential factors, thereby preparing baseline data for VR game development and other relevant studies.

어떤 집단에서든 그 구성원의 효율적인 관리가 무엇보다 중요하다. 이러한 효율적인 관리는 집단의 구성원이 많을수록 한 개인이 방대한 자료를 분석 및 관리하기에는 많은 어려움이 있다. 본 논문에서는 이 많은 자료를 바탕으로 퍼지 추론을 이용하여 근태 관리 시스템을 개발하였다. 먼저 퍼지입력 변수로는 출입구에 미리 설치되어 있는 지문 도어락과 관리실의 PC를 통해 사원들의 출퇴근 시간과 월별 근무시간, 월별 근무일수, 월별 조퇴 및 지각일수를 산출한 후 월별 휴가일수를 입력한다. 이 입력 데이터 값으로 퍼지 연산을 수행 후 구성원 개개인의 월별 성실도를 결정하였다.

In the financial industry, the decision tree algorithm has been widely used for classification analysis. In this case one of the major difficulties is that there are so many explanatory variables to be considered for modeling. So we do need to find effective method for reducing the number of explanatory variables under condition that the modeling results are not affected seriously. In this research, we try to compare the various variable reducing methods and to find the best method based on the modeling accuracy for the tree algorithm. We applied the methods on the pension insurance of a insurance company for getting empirical results. As a result, we found that selecting variables by using the sensitivity analysis of neural network method is the most effective method for reducing the number of variables while keeping the accuracy.

One of the theoretically and empirically grounded black boxes in HRD and firm performance link is employee' attitudes such as organizational commitment and job satisfaction. However, most studies were conducted with the regression analysis at the organizational level. This study used HLM(hierarchical linear modeling) analysis, which made it possible to estimate more accurate relationship between variables that were measured from two different levels. In addition, this study attempted to open an the black box(learning culture) in the relationship between HRD and employee attitudes. The result showed that the HRD have a positive effect on the organizational commitment and the job satisfaction. Also the HRD showed full mediation effect of organization commitment and the job satisfaction on the Learning culture. And the result showed that the HRD in 2007 have a positive effect on employee' attitudes in 2009. These findings concluded that systematic HRD like employee's education and training must be built and also the positive culture for employee's learning like support of management's learning organization must be improved in order to promote the organizational performance(organizational commitment, job satisfaction) in company.

This study aims to examine factors affecting small food service business performance, which is assumed to be dependent primarily on its outskirt's residents. In contrast to the prior research, this paper measures saveral location traits as a separate service business success factor without including the factor in management factors. The empirical results show that small food service's sales can be determined significantly by business career in entrepreneurs' background features. Secondly, its sales can't be influenced by any psychlogical factors such as a desire of achievement, a propensity of risk taking and locus of control. It is assumed that questions about psychological traits based by the prior research do not suit for small food entrepreneur. Thirdly, qualified product have a significant effect on its sales. Finally, its sales can be significantly impacted by the number of customer chair.

Given the increasing of adoption of use of Mobile Wireless Technology(MWT), this study aims at investigating the key influencing determinants of individuals' MWT adoption and use. Based on the Technology Acceptance Model(TAM), the research model proposed new constructs and casual relations, Perceived Safety(PS), Perceived Costs(PC), Company's Willingness to Fund(CWF), and Experience(E) as a moderator. The model was tested using Structural Equation Modeling(SEM) using AMOS 5.0 analysis on the sample collected from 387 MBA and Executive MBA students of several domestic and foreign universities. The results show that not only the variables, except Perceived Usefulness, in the original TAM model, but also new variables in the research model had a significant influence on other variables. The implications of the findings suggest a new theoretical framework for future IS/IT research and offers suggestions that the developers of MWT should consider regarding the technology

The purpose of this study is to extract relavant factors that affect military accidents. A survey was conducted for 227 officers and noncommissioned officers and 300 private soldiers. The survey results extracted 9 important factors that cause military accidents, including 3 troop factors, 3 social environment factors, and 3 personal character factors. Through a regression analysis using these 9 factors as independent variables and 4 types of military accidents as dependent variables, several factors were found to be very useful to explain military accidents. The findings of this study can be used to develop an early warning system for military accidents reduction.

The fashion apparel industries have demanded to be extremely consumer-oriented. Therefore, the need of personalization arises. The purpose of this study is to investigate the relationship between apparel shopping orientation and various personalization strategies provided in the apparel shopping process. A total of 422 questionnaires were used for statistical analysis. Canonical correlation and ANOVA were conducted. Results indicated that higher level of demand for "sale-promotion personalization" and "personalized customer relationship" were significantly related to high level of fashion innovativeness and price consciousness. Consumers who seek for high level of "personalized advice" and "personalized fit" were likely to be price conscious and conforming to clothing but not innovative in terms of fashion and clothing. Shopping orientation group differences were also reported in the study. In personalizing of apparel products, distinctive but relevant strategies should be implemented according to the need of the consumers.

The purpose of this study is to examine the moderating effects of perceived organizational justice on the associations between personal job-organizational fit and job loss perceived by social workers. The survey was conducted on social workers in Gwangju. This study conducted descriptive statistics, correlation analysis, hierarchical multiple regression analysis using SPSS 24.0 as an analysis method to verify the main assumptions of this study. The analysis showed that First, The degree of personal job-organizational fit was shown to be slightly higher than normal. perceived organizational justice was investigated as two sub-factors, and distributive justice was shown to be slightly lower than normal and procedural justice to be higher than normal. The degree of job loss was also investigated at a lower level than normal. Second, personal job-organizational fit had negative(-) effects on job loss and the effects were moderated by perceived organizational justice.
