Due to the high level of information supportive function of Internet, the management environment change is accelerating. The Patients are able to have the chances of Hospital- and Doctor-shopping. So the Customer Relationship Management skill or Patient -oriented management is becoming one of the important management method of Hospital. To adapt these trend, many Hospital invest the money and efforts for the implementation of Hospital CRM system. But the Performance of HCRM is not satisfactory for the investor from many reasons. In this paper we try to find out which kinds of factors have the Influences on the Implementation of HCRM, and how is the relation between these factors. We use the Structural Equation Model to clarify these relationships. The result of this paper will contribute in the decision making of the implementation of HCRM in the field, and in providing the knowledge base.

The increasing interest in the use of Automated Speed Enforcement (ASE) systems in Korea enables to enforce speed violation by National Police Agency. We have analyzed the mechanism of ASE systems on traffic safety throughout Korea. 1 The data collected on a 2km road-section of each 32 ASE stations during one rear period indicate significant safety improvement. The results were (a) a decrease in the total number of accidents of 28%, (b) a decrease in the number of fatalities of 60%. 2. The study also that ASE systems are effective to reduce average speed, speed variance, and short headway. 3. Based on the operational data collected at 15 locations, an aggregate safety prediction model is proposed as a multiple regressions form. The primary operational variables that appear to affect the frequencies of accident are : average speed, speed variance, and the number of vehicles exceeding 30km/h of posted speed limit.

Utilizing fit theory in strategic human resource management, this study examines the impact of two HR practices on newcomer turnover rates. While there is a growing body of research identifying the linkage between high-performance work systems(HPWS) and improved organizational performance through higer employee commitment, little research addresses how specific mechanisms among the systems deliver different performances to organizations. Using management by objective(MBO) and job rotation in HPWS, we found a strong main effect of each practice-it decreases newcomer turnover rates. This main effect becomes stronger when one practice combined with another, showing synergy exists. Linking HPWS research to turnover, this study provides insightful evidence of interactions between MBO and job rotation for organizational performance.

사회-수문시스템의 인과관계에 대한 보다 상세한 통찰하기 위해서는 현재의 사회-수문시스템의 기능을 이해하고 미래의 사회-수문시스템의 변화 궤적을 예상할 수 있는 모형이 필요하다. 사회-수문학적 관점에서는 수문순환 현상과 더불어 인간 활동과 관련된 인구, 토지이용, 경제성, 환경변화로 연계되는 사회-수문시스템 내 복잡한 관계해석 과정이 중요하다. 본 연구에서는 하천유지유량 결정기준에 따른 사회-수문시스템의 변화과정을 이해하고 가능한 영향궤적을 평가하기 위해 사회수문학적 관점으로 해석하고자 한다. 현재 우리나라에서는 하천유량고시지점 114개 중 각 항목별 고시지점의 비율은 수질(33%), 평균갈수량(33%), 생태(29%), 경관(4%), 수질 및 염해(1%)로 나타났다(2019년 고시 현황). 따라서 사회-수문시스템 내에서 하천유지유량 결정기준 차이에 따라 환경적, 사회적, 경제적 측면으로의 영향을 평가하기 위하여 구조방정식모형을 모델링 한 후, 모형 내 잠재요인(기상, 수문, 환경, 사회·경제)의 상호연관성을 파악하였다. 기상학적 요소로는 기온, 강수량을 선정하였으며, 인간의 활동이 개입된 수문학적 요소는 유량, 하천수이용량으로 선정하였다. 환경적 요소는 BOD, COD, SS를 선정하였으며, 사회·경제적 요소는 인구, 지가변동률을 고려하였다. 이와 같은 사회-수문시스템 내 잠재요인별 요소를 바탕으로 사회-수문학적 영향평가를 위한 가설을 검증하기 위해 통계 프로그램 AMOS를 활용하여 구조방정식모형을 모델링하였다. 향후 사회-수문학 관점에서의 복잡한 영향관계를 정량적으로 평가하고, 다양한 이해관계자 간의 합의를 도출하는 데 있어서 효율적인 의사결정도구로 활용될 수 있을 것으로 기대한다.

Many online shopping sites now offer personalized recommendation systems to improve consumers' shopping experiences by lowering costs (time, cost, etc.), catering to consumers' tastes, and stimulating consumers' potential shopping needs. So far, domestic and foreign research on the personalized recommendation system has mainly focused on the field of computer science, which is advantageous for obtaining accurate personalized recommendation results for users but difficult to continuously track the users' psychological states or behavioral intentions. This study attempted to investigate the effect of the characteristics of the personalized recommendation system in the online shopping environment on consumer perception and purchase intention for consumers using the Stimulus-Organism-Response (S-O-R) model. The analysis results adopted all hypotheses on the effect of the quality of the personalized recommendation system and information quality on trust and perceived value. Through the empirical results of this study, the factors influencing consumers' use of personalized recommendation system can be identified. In order to increase more purchase, online shopping companies need to understand consumers' tastes and improve the quality of the personalized system by improving the recommendation algorithm thus to provide more information about products.

This study attempted to analyze factors influencing S-DMB adoption. The theoretical background of this study is 'Technology acceptance model.' Based on this theory and literature review this study set 5 hypotheses. For this research, a survey was conducted by online research lab. from October 25 to 31. Data were collected from 350 subjects. Complete and useable questionnaires were received from 303 respondents. The result and conclusion are as follow: 'Instant accessibility,' 'service quality,' 'Cost,' 'advertising,' 'perceived easy of use' are significant factors influencing 'perceived usefulness'. 'Compatibility,' is a significant variable influencing 'perceived easy of use'. However, 'self efficacy' and 'innovativeness' are not significant factors influencing 'perceived easy of use.' The result of the analysis showed that most of the hypotheses were verified the same as preceding studies, but some results were different with the result of preceding studies. Therefore, it implies the characteristics of S-DMB different with other IT systems and mass media that were research subject mostly before, and it influences the result of this study as well.

A number of techniques have been studied for handling uncertainty in the development of expert systems. One of techniques adopted in many expert systems is the Dumpster-Shafer Evidence combination scheme. This has been the main focus among others due to is favorable features and computational complexity. In this paper, we develop and algorithm to deal with the exponential complexity inherent in Dempster-Shafer evidence combination. In the evidence combination process, we divide the frame of discernment into two groups, one for those common in both belief functions and the other for the rest. A property is found that in computing new belief function for the latter group, the result of evidence combination show linear change. The irrelevancy factor is derived and used to compute the change. The main idea of the method is to reduce the size of the frame of discernment and thus exponential complexity.

Learning by examples has proven to be an efficient method in mastering various subjects including programming languages. This study hypothesizes that the number of examples and the type of examples are two significant dimensions that influence the performance of learning programming languages by examples. A set of experiments was conducted to investigate the impacts of the two dimensions in the domain of JAVA programming. The results showed that providing two examples is more effective than providing only one example even though significantly more explanations are attached to the single example. Among the 'two-example' groups, the group that was given functionally similar examples performed better than those with functionally dissimilar examples. Explanations for these results are provided in this paper based on the behavioral patterns of individual subjects in terms of time and frequency. This paper concludes with the implications of the study results for the development of effective tutoring systems for programming languages.

This study was conducted for the torsional behavior of catwalk system which is a temporary structure on a suspension bridge. The torsional deformation of the catwalk structure has a significant effect on the workability and safety of workers during main cable erection. For this reason, the torsional deformation of catwalk is controlled to be acceptable levels below by adjusting the cross bridge interval in design stage. This study analyzed the effect of separation between cross bridge associated with twist safety of catwalk system. For the analytical approach, a detailed analysis model was created including cross bridge. Both wind load within the wind velocity range that allows the construction and eccentric load of Prefabricated Parallel Wire Strand were analyzed by analysis model. Result of study shows that separation between cross bridges has a significant effect on the torsional behavior of the catwalk.
