The purpose of this study is to examine the structural causal relationships between service image, service satisfaction, affective commitment, and customer loyalty to customers who have experienced hospital medical services, and to identifies the mediating effect of relationship proneness in explaining the effects of service image, service satisfaction, and affectivel commitment on customer loyalty. For this study, 250 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. Service image had significant influence on service satisfaction and emotional commitment. First, Service satisfaction was significant for emotional commitment and customer loyalty, and emotional commitment had a significant effect on customer loyalty. Therefore, the path relations between variables were all statistically significant. Second, there was differences the moderating effect of the relationship proneness in the effects of service satisfaction, service image and affective commitment on customer loyalty. In other words, the moderating effect of the relationship tendency was consistent with the research hypothesis and the adjustment effect was significant in the relationship between service satisfaction and customer loyalty. However, there was no control effect in relation to service image and customer loyalty and affective commitment and customer loyalty. Therefore, In order to secure long-term and stable profits by establishing a relationship with their customers, the medical service marketing strategies of hospitals should be promoted to enhance customer loyalty by raising the level of service satisfaction to high relationship proneness group and by raising the the level of affective commitment to low relationship proneness group.

Recently, Live-Virtual-Constructive (L-V-C) integrate training system has proposed as a solution for the problems such as limitation of training areas, increase of mission complexity, rise in oil prices. In order to integrate each training system into the one effectively, we should solve the issue about stress of pilots by the environmental differences between Live and Virtual simulation which could be occurred when each system is connected together. Although it was already examined in previous study that the psychological effects on pilots was occurred by the environmental differences between actual and simulated flights, the study did not include what the causal factors affecting psychological effects are. The aim of this study is to examine which environmental factors that cause pilots' psychological effects. This study analyzed the biochemical stress hormone, cortisol to measure the pilots' psychological effects and cortisol was measured using Enzyme-linked immunoassay (EIA). A total of 40 pilots participated in the experiment to compare the differences in pilots' cortisol response among live simulation, virtual simulation, and the virtual simulation applying three environmental factors (gravity force, noise, and equipment) respectively. As a result, there were significant differences in cortisol level when applied the gravity force and equipment factors to the virtual simulation, while there was no significant difference in the case of the noise factor. The results from this study can be used as a basis for the future research on how to make L-V system by providing minimum linkage errors and design the virtual simulator that can reduce the differences in the pilots' psychological effects.

The variable control in the inductive inference for the confirmation and verification when the experimental data are collected is studied by applying the principle of probability inference. The control in engineering experiments is to protect any effect by of intervening variable except primary independent variable on the dependent variable. By the special condition the possibility for developing a phenomenon will be maximized; otherwise, by the extraneous condition the possibility for developing a phenomenon will be minimized. By doing so, the control may provide insurance for the causal relationship between the certain prior event (independent variable) and the post-event (the dependent variable). Some experiments by using both elliptical trainer and tread mill under the variable control are performed in order to find the relations between the energy expenditure, the respiratory exchange ratio (RER), and the heart rate (HR) against the exercise speed.

This study conducted a survey on 414 industrial organization food service workers in the Kyungnam area to find out the effect relationship of the job characteristics of organization food service workers and its effects on job commitment and job satisfaction by recognizing the need for job application through the job characteristic model, which was the beginning of the intrinsic motivation theory for the job of organization food service workers. To accomplish the purpose of this study, the method to analyze the survey was undertaken by using the SPSS 23.0 and Amos 21.0 statistic package program via a data coding process for collected data processing. We can confirm from the analysis results that there is a statistically significant causal relationship in all factors, except task identity, which is a sub factor of job characteristic. This result reaffirms the results of previous research by showing that the worker must be allowed to ensure completion of the entire job when performing the job as the job itself is not one part of the processes. Decision-making autonomy must be given in the work process when the worker performs their job in order to raise job satisfaction and furthermore to increase job commitment. The limitation of this study is that there are limits that making generalization as the study was conducted on industrial organization food service workers in the Kyungnam area as extracted samples.

Recently, a symptom similiar to black spot caused by Alternaria kikuchiana on the pear leaves is prevailing in Naju, Chonnam Province. This experiment was conducted in order to clarify causal agent and to survey present status on it. Disease lesions on the leaves were brown or black brown in color, circle or irregular circle in shape, $2\~6mm$ in diameter, and faintly zonal. Central part of lesions was gradually changed to greyish-white. The causal fungus was identified as Alternaria kikuchiana Tanaka causing black spot of pear reported previously on variety I-sib-se-gi (Nijisseki) of pear. However, this disease differed from that of typical black spot reported already in some aspects; It occurred more highly on matured leaves than on young ones. And it occurred severely in varieties Shin-heung, Shin-ko, Man-sam-gil(Okusankichi) etc. which have been reported as resistant varieties, while slightly in varieties Cho-ok(Hayadama), Park-da-cheung (Hakadahare) etc. which have been known as susceptible ones. From the results described above, it is considered that this disease is due to the differentiation in pathogenicity of Alternaria kikuchiana Tanaka in that area.

This study tried to test hypotheses, using path analysis, whether the implementation factors of TQM have influences to organization performance through achieving the managerial goals of production, or not. This is an attempt to perform comprehensive analysis instead of using the simple correlation approach between the implementation factors and performances. In order to perform the empirical test, this study has surveyed 98 firms which acquired the ISO authentication and analyzed the data using the path analysis of AMOS. After testing the hypotheses of this study, the cause factor, i.e. TQM implementation factor, has effective influences to the goals of production system, and, also, the goals have a significant influence to managerial performance. Therefore, this study concludes that the implementation factors of TQM have significant effects on the managerial performance.

In this paper, scale efficiencies and relative efficiencies of R&D projects in Industrial Technology Program, sponsored by Ministry of Trade, Industry and Energy, Korea, are calculated and compared. For the process, various DEA (Data Envelopment Analysis) models are adopted as major techniques. For DEA, two stage input oriented models are utilized for calculating the efficiencies. Next, the calculated efficiencies are grouped according to their subprograms (Industrial Material, IT Fusion, Nano Fusion, Energy Resources, and Resources Technology) and recipient types (Public Enterprise, Large Enterprise, Medium Enterprise, Small Enterprise, Lab., Univ., and etc.) respectively. Then various subprograms and recipient types are compared in terms of scale efficiencies (CCR models) and relative efficiencies (BCC models). In addition, the correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies is calculated, from which the causal relationship between them can be inferred. Statistical analysis shows that the amount of input, in general, should increase in order to be scale efficient (CCR models) regardless of the subprograms and recipient types, that the 1st and 2nd stage relative efficiencies are different in terms of the programs and recipient types (BCC models), and that there is no significant correlation between the 1st stage relative efficiencies and the 2nd stage relative efficiencies. However, the results should be used only as reference because the goal each and every subprogram has is different and the situation each and every recipient type faces is different. In addition, the causal link between the 1st stage relative efficiencies and the 2nd relative efficiencies is not considered, which, in turn, is the limitation of this paper.
