A novel method of transient stability analysis is presented in this paper. The proposed method extracts data points near the basin-of-attraction boundary and then builds a support vector machine (SVM) model learned from the generated data. The constructed SVM classifier has been shown to reduce dramatically the conservativeness of the estimated basin of attraction.

The author examined the response of Armorclad rockfish, Sebastes hubbsi [MATSUBARA]to the surface attracting lamps (0.5W, 0.8W, 1W) line in the experimental water tank ($550L{\times}58W{\times}73H$cm). The attraction rate was investigated in accordance with the intervals of lighting and putting out hour (1,5 minute) when each of the attraction lamps was gradually switched off after they were switched on all at once. The results are as follows : 1. Total distribution rate of fish in the illuminated section was 61.6%(mean 12.3%) in case of 1 minute interval, and 41.0%(mean 8.2%) in case of 5 minutes interval. 2. Mean distribution rate of fish at the illuminated section : \circled1Distribution rate at interval of 1 minute were 12.7% in 0.8W, 12.4% in 0.5W and 11.9% in 1 W respectively. \circled2Distribution rate at interval of 5 minutes were 9.0% in 1W, 8.6% in 0.8W and 7.0% in 0.5W respectively. 3. Attraction rates of the last section showed a little increasing as illuminating time elapsed. A difference of attraction rates according to lighting source in 1 minute interval was bigger than that in 5 minute interval. 4. Attraction rate of fish in only last section switched on : \circled1Attraction rate at interval in case of 1 minute were 52.0% in 0.8W, 46.7% in 0.5%W and 45.3% in 1W respectively. \circled2Attraction rate at interval in case of 5 minutes were 32.0% in 1W, 24.0% in 0.8W and 14.7% in 0.5W respectively.

This article is designed to establish fundamental design criterion for theme park cast costumes in accordance with play type and space. There is an understanding that theme parks act as a play space that is designed to meet diverse playing desires. To analyze cast costumes, the theme park - 'Everland' in South Korea as an example, area was divided into attraction space and non-attraction space. Attraction space is mainly for full-scale play content areas and the non-attraction space is to enforce the attraction space experience. Roger Caillois's play theory states that there are 4 play types; Illinx, Mimicry, $Ag{\hat{o}}n$, and Alea. All 4 play types were shown through attraction and Mimicry at non-attraction. Each cast costume was analyzed in terms of apparel design elements - silhouette, textile, color, detail, and props - related to play type facility and cast role. Criteria for theme park cast costume designs were suggested based on the results. Illinx cast members who fulfill a safety-checking role wear high chroma warm color costumes with the accent on details in bodice cutting lines, collar edges, pockets, buttons and decorative ornaments. A complementary contrast is also used. The guidance cast in Illinx may wear a suit in bright/vivid color. Mimicry guidance cast costumes show meticulous perfection in imitation with the figure in its space. From head to toe, color, textile, and silhouette - every detail and even props should match the character. $Ag{\hat{o}}n$ cast costumes are strictly limited in detail and decorative ornament usage as well as in color, since they are in charge of the management and operation of a competition. Alea cast's role is a self-demonstrator. Alea cast members should be a real tarot card reader. However, a manual should control their costumes. A total of 10 cast roles at a non-attraction space should be designed to show job patterns clearly in accordance with the whole theme at the park.

This paper aims to propose a computational technique for estimating the region of attraction (RoA) for autonomous nonlinear systems. To achieve this, the collocation method is applied to approximate the Lyapunov function by satisfying the modified Zubov's partial differential equation around asymptotically stable equilibrium points. This method is formulated for n-scalar differential equations with two classes of basis functions. In order to show the efficiency of the suggested approach, some numerical examples are solved. Moreover, the estimated regions of attraction are compared with two similar methods. In most cases, the proposed scheme can estimate the region of attraction more efficient than the other techniques.

The purpose of this study is in identifying the attraction degree of Seonunsan Provincial Park by quantitative analysis. For this, landscape slide test was performed by questionaries. And multiple regression analysis and Factor analysis were performed far identifying the attraction degree of users. The attraction degree of natural resources was evaluated by questionaries about the landscape scene of 120 slides which was pictured at the chief visual corridor So it is considered that tourism route far attracting people into natural characteristic resources should be developed. It is identified once again that factors of $\boxdr$Naturalness$\boxul$,$\boxdr$Uniqueness$\boxul$and $\boxdr$Mysteriousness$\boxul$are important in natural landscape. And 16 explanation variables which explain the attraction degree of viewing landscape were classified as 4 factors. Those were defined as $\boxdr$Ability (FⅠ)$\boxul$, $\boxdr$Season harmony (FII)$\boxul$,$\boxdr$Simplicity (FⅢ)$\boxul$ and $\boxdr$Legibility(FⅣ)$\boxul$. It is identified that the variables of FⅠ, mysteriousness, is a representative image which expresses the characteristics of Seonunsan Provincial Park.

This study aims to examine factor of tourism attraction and tourism satisfaction in order to product plan of tourism policies related to architecture and urban design focused on Marado, Jeju Island. For that, a questionnaire is conducted by tourists who visit to Marado. The results are as follows. 30s and 40s tourists evaluate that Marado is more attractive in natural environment rather than 60s. Tourists who visit more than four times to Marado evaluated low in satisfaction for landscape of Marado but tourists who reside in other area not Jeju evaluate higher in satisfaction for landscape. The difference of residence areas shows same result in tourism attraction factors. Tourists participating in tour activities show higher in satisfaction rather than no-participants but the difference between participants and no-participants is not showed in tourism attraction factors. Tourism attraction is extracted four factors; natural environment, architectural environment, economic efficiency and psychological factor. The factors of natural environment and architectural environment have the relation with satisfaction but the factors of economic efficiency and psychology do not show no relation with satisfaction.

This study was initiated by the fact that Kangwon Land and large sized resorts was failed the financial benefit to the local residents. This research analyzed the best important tourist resource among the main tourist resource by perception interviewing local residents and related professionals. This study shows that the leisure resource was most important resource field in Jeong-Seon. So more attention to the leisure resources and investment them. Among natural attraction resources 'Hwa-Ahm cave and Hwa-Ahm mineral water' is estimated to have most potential for the strategic financial support. In leisure sector 'High One resort' is judged to be more important attraction resource by professionals but a case of local residents 'Dong-gang Rafting' and 'Rail Bike' were estimated more important resources rather than 'High One resort;. Lastly, in cultural resources, although the importance is a bit behind natural attraction and leisure resources, 'Jeong-Seon 5th day market' and 'Araree village' should be the core linking other related cultural resources. In order to activate tour industry and development of Jeong-Seon area, it is necessary to find identify of regional owned attraction resources and to build tourist attraction infra structure by selecting core bases of existing major attraction points and linking other various resources to those core bases.

Purpose - In this paper, we provide recommendations for Korea's long-term direction and strategic measures to attract inward foreign direct investment (FDI) in response to Japan's export regulations. In doing so, we analyze the current situation and characteristics of trade between Korea and Japan, focusing on the parts and materials industry, which is particularly affected by Japan's trade regulations. Design/methodology - Based on the analysis of five successful inward FDI cases (e.g. Toray, IGK, Delkor, GlobalWafers, DuPont) and statistic trend review in the parts and materials industry, we consider various factors pertaining to successful inward FDI in Korea and propose valuable investment attraction strategies. Findings - For a successful investment attraction strategy, we studied some statistical trends in the internal and external environments of the parts and materials industry and successful investment attraction cases in Korea. We have found that in order to increase the probability of success in attracting investment, we need a mid-to long-term strategy considering multiple factors such as "Production-oriented, Demand-linked, Global Value Chain (VGC) linked, and Policy-linked investment attraction." Originality/value - We suggest several specific measures and important strategic implications for the Korean government and firm's managers to attract inward FDI successfully.
