The purposes of this study were to examine the motivation of career choice for chefs in luxury hotels through IPA analysis based on the differences between importance and satisfaction, and to investigate the impact of motivations of career choice on job satisfaction. The results are as follows. First, "matched aptitude" and "interest in cook" were found as factors of importance and satisfaction. Second, sufficient reward should be provided through incentive, increasing salary, and promotion. Third, the system of internship and temporary employee should be revised, and the motivation should be provided through performance-based reward and incentive system. Fourth, fair personal evaluation, transparent promotion system, fair reward system should be required to increase job satisfaction. Fifth, internal environment is important rather than social reputation or popularity for those who consider chefs as future career.

Private security industry employers in Korea has not concerned with the importance of training and education by lack of recognition and has been passive about qualified guards. And the authorities supervising and the administrating the guards has not recognized the importance of private security and has neglected the training of the guards. Korea has been operated the guard-instructor system for the acquiring the specialization of the security personnel since 1997, but there has been many problems. This study reviews the guard-instructor system in Korea comprehensively and suggests the efficient operation method of that system.

Recently we extended the fuzzy model for rule based systems incorporating an importance factor for each rule. The model permits for both unrestricted as well as non-negative importance factors. We use this extended model to design a fuzzy rule based classifier system which uses both the firing strength of the rule and the importance factor to decide the class label. The effectiveness of the scheme is established using several data sets.

A quasi ideal importance sampling simulation method combined in the conditional expectation is proposed for the structural reliability estimation. The quasi ideal importance sampling joint probability density function (p.d.f.) is so composed on the basis of the ideal importance sampling concept as to be proportional to the conditional failure probability multiplied by the p.d.f. of the sampling variables. The respective marginal p.d.f.s of the ideal importance sampling joint p.d.f. are determined numerically by the simulations and partly by the piecewise integrations. The quasi ideal importance sampling simulations combined in the conditional expectation are executed to estimate the failure probabilities of structures with multiple failure surfaces and it is shown that the proposed method gives accurate estimations efficiently.

According to the results of Probabilistic Safety Assessment(PSA) for a Nuclear Power Plant(NPP), an Emergency Power Supply(EPS) system has been considered as one of the most important safety system. Especially, the interests in the reliability of the EPS system have been increased after the severe accidents of Fukushima Daiichi. Firstly, we performed the risk assessment and the importance analysis of the EPS system based on the PSA models of the reference plant, which is the Korean standard NPP type. Considering a portable Diesel Generator(DG) system as the reliability reinforcement of the EPS system, we modified the PSA models and performed the risk impact assessment and the importance analysis. Although the reliability of the potable DG could be about 20% of the reliability of the alternative AC DG, we identified that Core Damage Frequency(CDF) was decreased by at least 4.6%. In addition, the risk impacts due to the unavailability of the EPS system on CDF were decreased.

The purpose of this study was to define the content of physiological knowledge needed for clinical nursing practices. Subjects of physiology were classified into 15 areas, and each areas was further classified into subareas, resulting in a total of 194 subareas. The degree of importance of each subarea was measured with a 4-point scale. The subjects of this study were 179 nurses of two university hospitals located in Seoul and Inchon. The results were as follows : 1. The areas of physiology necessary for clinical nursing practice as a basic knowledge in the order of importance were : blood, respiratory system and renal physiology, function of the immune system, body fluid and cardiovascular system, body temperature, endocrine physiology and gastrointestinal physiology However, the degree of importance for reproductive physiology, neuro-physiology, energy and metabolism, cell and cell membrane physiology, muscular physiology and special sense was relatively low. 2. The most important content of physiology for all clinical areas in nursing was blood physiology. However, the degree of importance for each physiology area was different depending on clinical areas. 3. Subareas of physiology as a basic knowledge for clinical practice and education in nursing were blood transfusion, blood type, function of red blood cell, white blood cell and platelet, characteristics and function of hemoglobin, composition and function of plasma protein, and mechanism of blood coagulation and anticoagulation. In conclusion, areas of physiology necessary for clinical nursing practice were blood, respiratory system and renal physiology, function of immune, body fluid and cardiovascular system, body temperature, endocrine physiology and gastrointestinal physiology. However, the degree of importance for each physiology area was different depending on clinical areas In nursing.

Purpose: The purpose of this study was to determine the factors that influence the performance and importance of clinical nutritionists. Methods: Ninety-nine nutritionists working in mental health institutions were assessed. Results: Factors affecting the performance of clinical nutritionists in certified hospitals were shown to have a significant positive effect on the description of treatment diet, status of clinical nutrition management, and presence of a nutrition counselor. The factors affecting importance were the number of permission beds and total work experience. Conclusions: In order to improve the accreditation system of mental hospitals, it is necessary to expand the scope of this study to include hospitals with fewer beds, and clinical nutrition management should be mandatory.

Damage of national infrastructures not only endangers the structural safety, but also has a direct and indirect influence on national economy and society. Since the influence of damage has been enhanced in the metropolitan areas, the infrastructures in danger should be identified and managed under disaster situations. This study suggests the importance factors for national infrastructures, calculates weights for the factors through AHP analysis, and develops the importance evaluation system for national infrastructures. The evaluation system provides the priority of infrastructures for local governments and facility managers and enables management based on the degree of importance in emergency situations. After disasters, the evaluation system will support a systematic decision-making for recovery priorities with a limited budget.

This study attempts a comparison between AHP(Analytic Hierarchy Process) in which the importance weight is structured by individual subjective values and regression model with importance weight based on statistical theory in determining the importance weight of casual model. The casual model is designed by for students' satisfaction with university, and SERVQUAL modeling methodology is applied to derive factors affecting students' satisfaction with university. By comparison of importance weights for regression model and AHP, the following characteristics are observed. 1) the lower the degree of satisfaction of the factor, the higher the importance weight of AHP, 2) the importance weight of AHP has tendency to decrease as the standard deviation(or p-value) increases. degree of decreases. the second sampling is conducted to double-check the above observations. This study empirically checks that the importance weight of AHP has a relationship with the mean and standard deviation(or p-value) of independence variables, but can not reveal how exactly the relationship is. Further research is needed to clarify the relationship with long-term perspective.

Since the embedded system is more intelligent, the importance of the reliability in the embedded system is a lot more visible. Especially the reliability of the embedded system in the train control system is even better important. As the special quality of the embedded system, the hardware of the system is directly controlled by the software in the embedded system. As the expansion of complexity, the expense amd the time for verification is required more and more. This paper is presented the verification of the reliability as the method with background of failure Embedded system is gradually, the importance of 'A built-in on the system embedded system's reliability is focused. In particular, in the train control system built-in of the embedded system, reliability is even more important. The embedded system of the system controls over hardware, software with built-in directly. The more complex system is, the more increasable of depending on the reliability of the time verification and expensive is. This paper is about he characteristics of the reliability and verification of embedded system under the failure mechanisms, based on the verification methodology suggested by in the train control system.
