In multi-server environment there are many servers which are able to process job requests. So we bave to design a mechanism that selects appropriate servers for processing each job request while maximizing server throughput and minimizing average response time of requests. Conventional methods ac~ opt the load of each server as criteria of server selection. that is, they select a server whose load is not bigger than the others. In this work we propose an approach that uses the degree of server performance, server load and the estimated service time of requested job as guidelines of server selection. We incorporate fuzzification techniques and expert knowledge in this approach. Comparing the performances c~f our approach to that of conventional one, experiments show that the proposed approach provides better performances.

To explain the performance gap between firms in the same industry, this study focuses on innovation. It provides a new framework using the dynamic-capability view based on empirical analysis of domestic businesses. The findings of this study are as follows: First, when the uncertainty and competition intensity in the business environment and the level of innovation have “fit”, it means that when the former goes up, so does the latter. In this regard, when the innovation capability of a firm is high, being “fit” means that the level of innovation is also high. When there was fitting innovation on industrial environment and innovation capacity, companies were able to achieve relatively high performance. Also, it was confirmed that instead of innovation for innovation capacity, innovation for industrial environment led to relatively higher performances of firms.

This study investigates the impact of the shared environment of pregnant women and their unborn child on the later emotional and behavioral characteristics of a child, extending into his or her adulthood. Using a sample of some 16,000 children from the National Child Development Study, the study demonstrated a positive relationship between the quality of the maternal environment and later emotional and behavioral performances during childhood and adulthood. These findings support the study hypothesis, suggesting that parenting environment such as mother‘s employment, husband’s social class and the mother‘s smoking habits during pregnancy has an affection on the later emotional and behavioral development of the child. The dimensions of the child’s emotional and behavioral well-being may be enhanced by therapeutic interventions and/or by helping pregnant women to develop a positive social network.

Today, there are increasing evidences that daylight is essential for health, well-being and productivity. One of the strong contributions, which atria can make to advantages in building, is in allowing the use of daylight. This research is to develop nomographs and to evaluate the daylight performances of toplit atria with louvers. For this purpose, the evaluation models of toplit atria with well indexes of 0.5, 1.0 or 2.0 have been selected through the field surveys of atrium buildings in Seoul area. Also, weather data for solar irradiance and luminous efficacy were gathered from the recently conducted previous researches. The computer simulations were performed under clear sky conditions, using the ADELINE program, and various daylight performances were analyzed by the daylight illumination ratio. Analyzing the simulation results, solar altitude, solar azimuth, and louver angle and louver reflectance were found to be important factors affecting the daylight performance of toplit atria. Using these variables, regression equations have been formulated, and the nomographs, which may predict the daylight performances of toplit atria with louvers, were developed. The developed nomographs were validated through comparing the results of nomograph predictions to the results of scale-model experiments.

Purpose: Prefabricated modular space such as a container construction has recently been interested unlike the conventional construction method, and their scale have expanded from small buildings such as cafes, houses and pensions to shopping centers, complex cultural spaces where shows and exhibitions are possible doing. In this way, the container is in the spotlight as an advantage such as mobility, flexibility, correspondence, economic efficiency, recyclability and so on. However, there are no specific guidelines and standard design methods in aspects of structural calculation, functional insulation and environmental configuration. Therefore, as the first step to resolve these problems, this study has focused on the field of environmental performance of container construction, presented appropriate guidelines and searched ways to improve performances. Method: For this study, seven types of the modular building were chosen and compared, and their energy performances have been analyzed using a proven simulation tool. Essential methodology and terminology were examined to estimate and judge their efficiency. Result: In conclusion, energy performances depend on specific configuration of combined unit spaces, and design guidelines cold be set up for promoting their use in the practical field.

Various problems regarding the wet floor method such as its complicated process and waste of thermal storage have been raised, but the usage of dry floor recommended for long-life housing has declined due to lack of confidence on the performance of dry floor. The purpose of this study is to secure the credibility of dry floor. Under this purpose, this study considered precedent studies and established directions to secure the performance of long-life housing infill, and thus, 9 performance items (Impact sound, Smoothness, thermal comfort, sensation hardness while walking, falling safety, impact resistance, local compression load, local strength and strain at heating) were drawn. In addition, the experiment was carried out for 5 performances except for legal performance, some dry floor performances and whole spatial performance. As a result, an appropriate result from all performances except was obtained. The performance of dry floor was verified for each item from these results and it is expected to use such results as basic data on dry floor in the future.

For the purpose of enhancing performances, many companies have tried to ensure the competitive advantages in ties with organization's strategy by putting effort in designing, developing and practicing the information system. Despite the information oriented small and medium enterprises (SME) being suffered from lack of funds, professional man-power and poor environment, fairly evaluating the level of information system within an organization can be a positive starting point for information oriented SME. Therefore in this study, for the purpose of using the SERVQUAL as a measurement tool provided by information system department under the environment of using information system, we try to free from the marketing oriented service category and develop models that are applicable in the information system environment to check reliability and validity. As a result, it is analyzed that enhancements of SERVQUAL simultaneously improves system and information quality which makes the employees satisfy with their working environments and sequentially affects to the collaborative performance of using information system.

According to resource based view, knowledge is regarded as a salient factor to improve an organization's efficiency in the current fast-changing business environment. Knowledge management (KM) may encourage employees to share and exchange knowledge in the organization in order to improve and sustain a competitive advantage over other companies. The proposed research model examines the impacts of KM performances' antecedents on an employee's absorptive capacity. This study identifies KM performances as employee's satisfaction about KM and shared knowledge quality. This study considers KM performances as the major determinants that enhance his/her absorptive capacity. This study also investigates the key antecedents of KM performances. The research model posits extrinsic reward, intrinsic reward, and relational reward as the KM performances' antecedents. Furthermore, this study examines the difference of the antecedents' effects in terms of firm's type. The proposed research model was tested by using survey data collected from 1,103 employees of 2 public enterprises and 907 employees of 5 private enterprises. The findings of this study showed that employee's satisfaction about KM and shared knowledge quality play a significant role in enhancing employee' absorptive capacity. Extrinsic reward only significantly influences employee's satisfaction about KM, whereas both intrinsic and relational rewards serve as the salient antecedents of improving both KM performances. The results also shed light on the moderating role of firm's type. Theoretical and practical implications of this study are discussed.

This study aims to explore the difficulties of Korean dance instructors targeting senior people and extends the difficulties found to developing PBL problems applicable to the instructors' education. To address the goal, this author employed an open-ended questionnaire consisting of four questions and 1:1 interview and collected data. According to the study results, total nine subfactors were drawn from four difficulties associated with student management, the curriculum, performances, and class environment. First, about difficulties related to student management, 'conflicts between students' and 'demand for personalized class' were explored. Second, regarding difficulties about the curriculum, 'refusal against new teaching methods' and 'level difference according to the ability of acquisition' were explored. Third, concerning difficulties related to having performances, 'lack of time for practicing', 'needs to achieve excellent performances', and 'the administration of organizations in charge' were explored. Fourth, about difficulties associated with class environment, 'environment in general' and 'spatial environment' were explored. Also, based on the difficulties explored from dance instructors for senior people, this researcher has developed four PBL problems through community dance for harmony, joint choreography-based creative dance, playful dance allowing role division, and mirroring-based dance.
