The purpose of this study is to identify the factors that customers perceive as important relationship investment in the relationship efforts provided by retailers for customer relationship purposes and to explain the mediating role of relationship quality such as trust, relationship commitment in the relationship perceived relationship investment and relationship performance. For this study, 270 respondents were surveyed and data were analyzed using SPSS 21.0 and AMOS 20.0 statistical package. Statistical analysis tools, such as SPSS 21.0 and AMOS 20.0 were utilized for ensuring the validity and the reliability, whereas the SEM method was used for testing the research hypothesis. The results of study are as follows. Financial efforts and structural efforts have affected perceived relationship investment. Perceived relationship investment affected trust and relationship commitment but not loyalty. Trust influenced relationship commitment and loyalty whereas relationship commitment did not affect loyalty. Therefore, it is important for retail marketing managers to provide tangible rewards and special benefits at all times in order to recognize that they are doing the best service efforts for customer relations. In order to secure long-term and stable profits by establishing a relationship with them, the service marketing strategies should be promoted to enhance the relationship quality by raising the level of trust.

This study was designed to examine the relationships among the levels of perceived stress, dietary behaviors, physical exercise, drinking, smoking, and relief from fatigue through sleep which affect the subjective happiness in adolescents. Based on the study findings, this paper proposes the basic data required for offering practical solutions to improve the subjective happiness of adolescents. IBM SPSS 20 and AMOS 23 were used to conduct frequency and descriptive analyses, in conjunction with Pearson's correlation coefficients, the AMOS bootstrapping method and phantom variables, for the raw data obtained from the 9,599 participants included in the 11th Korea Youth Risk Behavior Web-based Survey. Those factors having a direct effect on the subjective happiness of the adolescents were the level of perceived stress, relief from fatigue through sleep, physical exercise, dietary behavior and smoking. Perceived stress had an indirect effect on subjective happiness, and the analysis of the indirect effect and significance level of multiple mediators by means of phantom variables showed that, as well as perceived stress, relief from fatigue through sleep, physical exercise, dietary behaviors, and smoking also had indirect effects on subjective happiness. Consequently, a multidisciplinary approach is needed to optimize the subjective happiness in adolescents and financial support for environmental improvements is particularly necessary.

Recently we can see many cases that the CRM Systems are implemented and operated in Hospitals. The reason for such situation is the management environments in medical service market is changing rapidly one hand, and on the other hand the competitions among the Hospitals became more severe. In this paper we try to present the factors and weights as index for the measurement of Hospital CRM's System Performance. To achieve this goal, we derived the primary factors for the success of the CRM Systems based on the precedent researches, and futhermore carry out the verification of the rightness of those factors. For the verification of the rightness of the factors, we employ the Structured-Model-Analysis Method of AMOS. This enhance the meaning of the analysis result of the factors. And we use the AHP method to compare the importance grade of each success factors, because the comparison of importance level of each success factor is very crucial for the measurement of the Hospital CRM's system performance. As a result, we derived the primary factors and analyzed the weights in this paper, which might be used as the guiding Index for the measurement of the Hospital CRM' System Performance.

Plant phenology including flowering, leaf unfolding, and leaf coloring in a forest is important to understand the forest ecosystem. Temperature rise due to recent climate change, however, can lead to plant phenology change as well as snowfall in winter season. Therefore, accurate monitoring of forest environment changes such as plant phenology and snow cover is essential to understand the climate change effect on forest management. These changes can monitor using a digital camera system. This paper introduces the detection methods for plant phenology and snow cover at the mountain region using an unmanned camera system that is a way to monitor the change of forest environment. In this study, the Automatic Mountain Meteorology Stations (AMOS) operated by Korea Forest Service (KFS) were selected as the testbed sites in order to systematize the plant phenology and snow cover detection in complex mountain areas. Multi-directional Internet Protocol (IP) camera system that is a kind of unmanned camera was installed at AMOS located in Seoul, Pyeongchang, Geochang, and Uljin. To detect the forest plant phenology and snow cover, the Red-Green-Blue (RGB) analysis based on the IP camera imagery was developed. The results produced by using image analysis captured from IP camera showed good performance in comparison with in-situ data. This result indicates that the utilization technique of IP camera system can capture the forest environment effectively and can be applied to various forest fields such as secure safety, forest ecosystem and disaster management, forestry, etc.

Real life problems can be expressed as a congruence modulus n and split into a system of congruence equations in modulus factors of n. A system of congruence equations can be combined into a congruence equation under certain conditions. This paper uniquely presents and critically reviews the generalized Chinese Remainder Theorem (CRT) for combining systems of congruence equations into single congruence equations. Sequential and parallel implementation strategies of the generic CRT are outlined. A variety of unique applications of the CRT are discussed.

This paper presents Lattice-Boltzmann simulation techniques for single-phase and two-phase fluid flow in porous media. Numerical experiments were performed in a digital rock sample from X-ray microtomography. Computed results showed very good agreement with laboratory measurements of permeability and relative permeability. Two applications using these simulation techniques show the potential of the Lattice-Boltzmann flow simulation to solve many difficult problems coupled with fluid flow in porous media.

When people enjoy something, they want to be repeated and focus on actions that are rewarded. The same applies to games. The purpose of this study is to ensure that the game continues to enjoy itself over and over again. Based on the artificial reward of the game, two reward methods of the game are studied. It finds Converged Difficulty Reward elements of action game through Confirmatory factor analysis in AMOS.

서비스 제공자와 고객 상호간에 상호작용의 특성을 밝히려는 연구는 광범위하게 진행되어 왔지만, 기술 접점(technology interfaces)에서의 고객과의 상호작용에 관한 연구는 다소 적은 편이었다. 본 연구는 이러한 관점에서 기술적 혁신과 진보가 고객-기업 상호작용의 중요한 요소가 되어가고 있는지를 확인하려고 하였다. 이러한 연구목적을 달성하기 위하여 인터넷 서비스접점 품질과 고객만족에 미치는 요인들과의 관계를 SPSS 10.0 과 AMOS 4.0 프로그램을 이용하여 실증분석 하였다. 연구결과 인터넷 서비스접점 경험을 개선할 수 있는 디지털 기술의 역할을 확인할 수 있었다. 즉 기업의 웹사이트 이용이 고객에게 보다 나은 가치 있는 편익을 제공에 기여할 수 있다는 것이다.

The purpose of this study was to examine the influence of educare teachers' science education knowledge and attitudes towards science on science teaching anxiety. 259 teachers of young children were recruited from 19 daycare centers and the data were analyzed through frequency, percentage, Pearson's correlations using PASW 18.0 and structure equation modeling using AMOS 7.0. The findings are as follows. First, educare teachers showed more than median scores in all science education knowledge, attitude towards science and science teaching anxiety. Second, in total 57% of the variance in teachers' science teaching anxiety was accounted for by teachers' science education knowledge and attitude towards science. This result implied that teachers' science education knowledge and attitude towards science should be improved in order to reduce teachers' science teaching anxiety.
