This study aimed to provide basic data on how to strengthen competitiveness and operate efficiently by differentiated selection attributes by identifying the influence between satisfaction and continuous participation intention, focusing on the selection attributes of Taekwondo studio perceived by parents. Therefore, parents who had registered at a Taekwondo studio located in the metropolitan area and participated in their children were selected as samples and surveyed from February 1 to 26, 2021, and a total of 386 copies of data were used for the final analysis. Data processing used the SPSS (ver.21.0) program to conduct frequency analysis, exploratory factor analysis, internal consistency, correlation analysis, simple and multiple regression analysis. The main results of this study are as follows. First, the selection attributes of Taekwondo studio has been shown to influence the satisfaction in the order of facilities and environment, master, cost and program. Second, the satisfaction has been shown to influence the continuous participation intention. Third, the selection attributes of Taekwondo studio has been shown to influence the continuous participation intention in the order of accessibility, facilities and environment, master and program.

The purpose of this study was to identify cosemetics purchasing behavior of male college students by clothing involvement. A questionnaire was administered to 246 male collage students living in Taegu and Seoul during September of 1999. Data were analyzed by using frequency, cross tabulation, t-test, χ²-test and factor analysis. The results of this study were as follows : First, the consumers are classified into two categories by clothing involvement ; 65.5% of the highly involved consumers and 34.5% of the lowly involved consumers. Second, the factors of selecting cosmetics were fragrance, quality and price. Third, the major information sources of cosmetics are TV, magazines, outdoor advertisements, newspapers, subway, radio and internet in order of importance. Fourth, high clothing involved group was more fashion oriented and showed more impulsive purchasing attribute.

The purpose if this study is to analyze the psychological preference of Family Restaurants and their behavioral characteristic and its segmentation, positioning, new product development and marketing min. Result of analysis, index and type of MBTI psychological preference are related to Family Restaurant Choice attributes intimately. Specially, "Menu composition reflected restaurant image", and "Providing of corresponded value to price"were shows considerable difference according to psychological preference. And "Providing of the corresponded value to price"of Value, Price and Image Factor, indexes, types, including all the other aspects, shows the most considerable difference. Therefore, all market of Family Restaurant when inventing or designing a menu, they should consider restaurant′s concept and image to manage a menu, and keep in mind that all customer take "value"at up most importance.

The purpose of this study was to identify convention service attribute that affecting participants' satisfaction and intention-to behavior. theory and existing literature related convention service are reviewed. Based on the literature review, the measurement scale was developed and used for collecting the data. A total of 171 useful sample was collected and utilized for the study. factor analysis, regression analysis, cluster analysis, and ANOVA were operated in SPSS. Three convention service factors were identified. It was found that these three factors affected participants' convention satisfaction and intention-to-behavior. Theoretical and managerial implications were discussed.

Within a mechanical system such as an automotive the number of standard machine parts is increasing, so that the parts selection becomes more important than ever before. Selection of appropriate bearings in the preliminary design phase of a machine is also important. In this paper, three decision-making approaches are compared to find out a model that is appropriate to bearing selection problem. An artificial neural network, which is trained with real design cases, is used to select a bearing mechanism at the first step. Then, the subtype of the bearing is selected by the weighting factor method. Finally, types of peripherals such as lubrication methods are determined by a rule-based expert system.

It can be characterized that contemporary architects intend to establish architectonics which can make it possible to reinterpret the attribute of movement in space and its programming differed from the traditional perception in moving in and out any space through disjoining and reorganizing human behavior and event. This intends reflect new paradigm for subjugating the compelled fuctioning of modern Architecture. This Study review those intends focused on programming as a pre-disign schema. In those intends, it connotes the effort of establishing more systemic and logical approach through deconstruction and disprogramming the existing from, space, elements and human on the basis of his own schematic conception as substitution of function in modern architecture.

In order to investigate the Phenomenon of Acid Precipitation, pH value and Anions of Fluroide, chloride, nitrite, phosphate, bromide, nitrate and sulfate were measured from the acid precipitations sampled around 7 districts over seoul area during period of 9 months from January till September, in 1985. From the distribution of pH value gatnered, acid precipitations were noticed during period from January till Aprill, and from as of April 22nd, situation gradually recovered. The average pH value till April showed comparatively low, ranging 4.0-5.0. The pH value of 4.5-5.6 in average over whole year reaches to similar level of those in Japan. Anion analysis revealed that the main factor of pH value in Seoul district attribute mainly to the sulfate ion and nitrate ion. Moreover, these Phenomena of acid precipitation in Seoul area appeared to concentrate on certain districts, and they are slowly moving toward other directions due to such factors as wind-velocity and directions.

In a competitive and globalized business environment, the need for the green products becomes stronger. To meet these trends, the environmental assessment besides delivery, cost and quality of products should be considered as an important factor in new product development phase. In this paper. a knowledge-based approximate life cycle assessment system (KALCAS) for the collaborative design environment is developed to assess the environmental impacts in context of product concept development. It aims at improving the environmental efficiency of the product using artificial neural networks consisting of high-level product attributes and LCA results. The overall framework of the collaborative environment including KALCAS is proposed. This architecture uses the CO environment to allow users on a wide variety of platforms to access the product data and other related information. It enables us to trade-off the evaluation results between the objectives of the product development including the approximate environmental assessment in the collaborative design environment.

To analyze the load of distribution line, real LPs (Load Profile) of AMR (Automatic Meter Reading) customers and VLPs (Virtual Load Profile) of non-AMR customers are required. Accuracy of VLP is an important factor to improve the analysis performance. There are 2 kinds of methods to generate the VLP; one is using ALP (Average Load Profile) per each industrial code and PNN (Probability neural networks) algorithm; the other is using LSI (Load Shape Index) and C5.0 algorithm. In this paper, existing researches are studied, and new method is suggested. Each methods are compared the performance with same LP data of real high voltage customers.

This paper presents an application of Kohonen neural networks to assess the dynamic security of power systems. The dynamic security assessment(DSA) is an important factor in power system operation, but conventional techniques have not achieved the desired speed and accuracy. The critical clearing time(CCT) is an attribute which provides significant information about the quality of the post-fault system behaviour. The function of Kohonen networks is a mapping of the pre-fault system conditions into the neurons based on the CCTs. The power flow on each line is used as the input data, and an activated output neuron has information of the CCT of each contingency. The trajectory of the activated neurons during load changes can be used in on-line DSA efficiently. The applicability of the proposed method is demonstrated using a 9-bus example.
