The purpose of this paper is to figure out T'oegye's philosophy and its characteristics in comparison with Zhuzi's. T'oegye is well-known as the representative of Neo-confucianism in Korea. But his posterior scholars and even contemporary scholars have various viewpoints about his philosophy. So they give him some different evaluation. After Zhuzi's death 300 years later, T'oegye has accepted Zhuzi's philopophical thoughts. In addition, he has added his own philosophical insights on them. First, he indicates concretely the metaphysical activity of li through lidong that Zhuzi has mentioned in some measure. Second, under the ontological aspect of li, he explains that Four beginnings come from li. It implies that li manifests and qi follows. Finally he points out lidao--i.e. li manifests itself, about wuge in his epistemology. Here we can say that whatever his metaphysics/the theory of mind and heart, and epistemology, the whole system of T'oegye's philosophy has its theoretical coherence. He has succeeded Zhuzi's philopophical thoughts thoroughly and furthermore developed Neo-confucian theory in East Asia that has not made before.

The rainfall depth-area-duration analysis which is used to characterize precipitation extremes for specification of so-called design storms, provides a basis for evaluation of drought severity when storm depth is replaced by an appropriate measure of drought severity. So we propose a method for constructing drought severity-area-duration curves in this study. Monthly precipitation data over the whole Korea are used to compute SPI. Such SPIs are abstracted to several independent spatial components from EOF analysis. Using Kriging method, these spatial components are used to constitute grid-based SPI data set over the whole Korea including Jeju island with $6km{\times}6km$ resolution. After identifying main drought events, the drought severity-area-duration curves for these events over 32-year period of record are finally constructed. As a result, such curves show the similar shape with storm-based curves in the sense that the drought severity (or rainfall depth) is inversely proportional to drought area from the curves, but drought-based curves are different from storm-based curves in the sense that the drought severity decreasing rate with respect to drought area is much less than depth decreasing rate.

In a buyer-seller transaction process, 'value for money,' a measure of quality-price-ratio, is one of the most important criteria for buyers' purchasing decisions. The purpose of this paper is to suggest a method which helps online shoppers choose the best of several sellers offering homogeneous goods. We suggest FDH (free disposal hull) model, an applied model of data envelopment analysis (DEA), for online buyer-seller transactions and verify it with the data from an Internet comparison shopping site. For this purpose, we analyze consumer choice behaviors by examining how consumers respond to different sale conditions such as price, brand, or delivery time. Then, we implement a seller recommendation system to support buyers' purchasing decisions. We expect our FDH model to provide valuable information for rational buyers who want to pay the least price for high quality products/services and to be used in implementing automated evaluation processes in micro transactions. Moreover, we expect that our results can be utilized for sellers' benchmarking strategies which help sellers be more competitive by showing them how to attract buyers.

This study is on the strategy for establishing successful corporate brand image, by understanding the need for increasing brand value based on the level of brand recognition. In order to carry this out, the PICS (Product Image Concentration System) is suggested, which includes Brand Image Analysis on a high-level, Product Image Programming based on the result of the image analysis, and Product Image Coherency Assessment and Management, resulting in setting up a guideline for gaining competitive advantage and brand management. Brand Image Analysis is a method that utilizes image association to understand brand disposition by analyzing the association pattern among available visual materials to measure the corporate and brand image inclinations. As the next step, Product Image Programming establishes design philosophy and principles based on the analysis of brand image, and the Visual Programming is a process for visualizing the intended product image direction. Lastly, Product Image Coherency Assessment examines whether to incorporate design philosophy and principles or not to arrive at an agreed evaluation criteria for developing designs coherent with the brand image. The PICS (Product Image Concentration System) is a practical method for increasing a company' competitive advantage and managing brand. The expectation on this system is to provide a guideline for applying brand image in design process more objectively. For further study, diversification of image spectrum based on expressive keywords and comparative analysis on images as well as a product image interpretation program to understand the order of visual materials will be necessary.

This paper aims to measure and evaluates the technical efficiency with two inputs and four outputs with the use of fuzzy DEA(Data Envelopment Analysis) in Korean RCC(Rescue Co-ordination Center)/RSC(Rescue Sub-Center). Especially, this paper included not only the marine accident data which occurred for the analysis in particular but also the possibility data of a potential marine accident by an Environmental Stress value and analyzed the technical efficiency. And in this paper, asymmetrical triangular fuzzy number is presented about inputs/ outputs data and a procedure is suggest for it solution. The basic idea is to transform the fuzzy CCR model into a crisp linear programming problem by applying an alternative ${\alpha}-cut$ approach. Also this paper propose a ranking method for fuzzy RCC/RSC using presented fuzzy DEA approach. The result, when ${\alpha}-cut$ is 0.5, efficiency priority should be in order to YS, BS, MP, TS, JJ, PH, US, IC, SC, DR, GS, TA, WD RCC/RSC. Finally, Inefficiency TA, WD RCC/RSC have to benchmarking with reference sets.

Ground resistance measurement is an elementary technique for the evaluation of grounding system. There are main environmental factors to consider for correct measurement but the problem is that it is practically most cases to measure ground resistance unable to know the factors. This paper presents a methodology toward true value of resistance in the unknown circumstances, utilizing the defined term 'variation rate' of potential difference curve appearing in the distance to a current probe as in the three point fall-of-potential method which comprises the characteristics of environmental factors. This methodology is a induced result from the previous demostrated studies.

This study analyzed the non-cognitive domains (self-management competency, interpersonal relations competency) and cognitive domains (physical communication competency, comprehensive reasoning ability) among K-CESA for college students in the Division of Architecture at 𐩒𐩒 University and construction company workers, after which a training program for college students was designed. A K-CESA diagnostic evaluation was conducted on 25 construction company workers and 36 students in the senior and junior years of the division of Architecture. To identify the discrepancies among the two groups, "One-way ANOVA", a mean difference test, was performed and the Scheffe verification system was conducted as an after-measure. The empirical analysis of this study was verified at the significance level p <.05, and statistical processing was analyzed utilizing the SPSS WIN. 23.0 program. The major findings are as follows: first, the significant point of difference between the college students and construction company workers were located in five skills (goal-oriented planning and execution skills, cooperative skills, intervention skills, leadership skills, speaking skills, analytical reasoning skills); second, the education program was developed to improve the goal-oriented planning, execution ability and analytical reasoning ability through the expert-required analysis and study research. Through follow-up studies, I suggested that there is a need to develop courses that compare the competencies of various majors and workers in public institutions, corporations and other organizations.

This study investigated body-related values, body-esteem, and the relationship between them based on the survey data drawn from female college students in three East Asian countries(Korea, Japan, and China). 168 Korean, 108 Chinese, and 152 Japanese female college students responded to questions designed to measure four sorts of body values (operability, inclination, locus of evaluation, and social utility) and four dimensions of body esteem (appearance, weight, health, overall). The results showed that body-related values and body-esteem differ among three countries. Japanese showed the highest acceptance level for the voluntary body alteration(operability), while chinese scored the lowest. Inclination to body appearance over health was higher in Korean than in Japanese and in Chinese. Korean also evaluated the importance of body appearance and its social utility the highest, followed by Japanese and Chinese. There were dramatic differences in body esteem between Korean and Japanese. Regarding body-esteem, Korean showed the highest appearance-esteem, but the health-esteem was the lowest. On the contrary, Japanese showed the highest health-esteem, but the appearance-esteem was lowest. Chinese showed the highest weight-esteem. Four sorts of body values showed significant correlations with appearance-esteem and weight-esteem, respectively but not with health-esteem. Overall, the result supported the prediction that different political, social, and economic backdrops in three countries would be related with different body-related values and body esteem in the female college students.

In mobile content services like apps for smart mobile devices in specific, there has been a growing interest in evaluating UX quality to make sure that it provides better experience to users and consequently, secures competitiveness in a market. In that sense, usability testing has been considered as one method that enables designers and design managers to evaluate UI quality before they launch their service. However, those designers have been faced with a following fundamental question to be answere d : Is good UX design a good business? In other words, can well-designed service, which has good usability, actually satisfy target users and improve competitiveness in a market? There is no doubt that usability is one important factor perceived by users. However, it has a limit in terms of evaluating UX quality in macro level, as it mostly focuses on ease of use and efficiency of performing tasks, but does not cover other possible experiential factors, which also can be perceived by users, such as market situation and preexistence experience. Therefore, this research aims to identify key experiential factors in using mobile content services, and establish service UX index model that enables to measure perceived user satisfaction, and identify how UX design contributes to the satisfaction in quantitative way.

In this paper, we propose the comparison method of pattern similarity for video segmentation algorithm. The shot boundary type is categorized as 2 types, abrupt change and gradual change. The representative examples of gradual change are dissolve, fade-in, fade-out or wipe transition. The proposed method consider the problem to detect shot boundary as 2-class problem. We concentrated if the shot boundary event happens or not. It is essential to define similarity between frames for shot boundary detection. We proposed 2 similarity measures, within similarity and between similarity. The within similarity is defined by feature comparison between frames belong to same shot. The between similarity is defined by feature comparison between frames belong to different scene. Finally we calculated the statistical patterns comparison between the within similarity and between similarity. Because this measure is robust to flash light or object movement, our proposed algorithm make contribution towards reducing false positive rate. We employed color histogram and mean of sub-block on frame image as frame feature. We performed the experimental evaluation with video dataset including set of TREC-2001 and TREC-2002. The proposed algorithm shows the performance, 91.84% recall and 86.43% precision in experimental circumstance.
