We report a case of an angiosarcoma arising from the subclavian artery, a site not previously described. A 19-year-old girl, born with a rudimentary first rib, has been suffered from arterial thoracic outlet syndrome due to a complete occlusion of the third portion of the subclavian artery for 1 year. Partial claviculectomy, excision of completely occluded arterial segment, and reconstruction with great r saphenous vein graft were done. Histologic study for the subclavlan artery revealed mural type anglosarcoma. The histochemici1 staining for factor VIII related antigen was positive. The debilitating symptoms that did not allow her a normal daily life, almost subsided postoperatively. And she has remained well with no clinical evidence of disease for 4 months post-operation.

Many various kinds of tourism resources have been distributed along the Nakdong river basin. Previous researches have focused mainly on environmental studies, including water quality control, industrial use of water, biodiversity, etc, with little research done in the field of tourism studies. Central to this study, therefore, is the identification and analysis, from the perspective of cultural tourism, of the area's distribution and characteristics of cultural properties registered by the MOCT. Review of related literature reveals : 1) spatial range bound with the jurisdiction of the river basin like DREO and NRBEO ; 2) analytical subjects limited to cultural properties designated by the three different administrative units of government, city and province. Along with the DREO's predominance over the NRBEO in the total number of cultural properties, the result finds that two cities, Andong and Gyeongju of Gyeongbuk are assigned ownership of most of the cultural properties under the jurisdiction of DREO, while Gyeongnam that of most of the ones under the NRBEO. However, those findings suggest the simple number of cultural properties with no significant level of importance and rarity value reflected. Therefore, future studies need to develop quantified modelling keeping cultural variables in mind and create cultural indices of the competitiveness of the local governments.

This study was to analyze the visual preference of the port landscapes for North port in Busan. Preference related variables came from Semantic Differential(SD) method and then were conducted by the factor analysis. Multiple regression was done for the relationship between the preference and factors. The result found 4 factors, including dynamics, stability, pleasantness and healthiness. Much importance was placed on dynamics among them. Therefore, building port landscapes and their image attracting viewers should consider dynamics in terms of port landscape plan and user attraction development for visual quality management.

Purpose : The purpose of this study was to investigate the effects of the virtual reality exercise program on ankle balance with ankle taping or microwave. Methods : This study was performed on 18 subjects. Eighteen subjects were divided into two groups; conducted virtual reality exercises with taping (n=9), and performed virtual reality exercises after microwave application (n=9). Both groups performed the exercise three times a week for four weeks. The data was analyzed by the Wilcoxon signed-rank test for comparing before and after changes of factors in each group and performed the Mann-Whitney test for comparing groups. Result : Taping and microwave groups were increased dynamic balance after virtual reality exercises (p<.05). There was no significant difference in balance after applying taping and microwave for virtual reality exercises (p<.05). Conclusion : Reducing the frequency of recurrent ankle sprain in functional ankle subjects, it is recommended to perform virtual reality exercise after applying taping and microwave.

This study is to integratedly examine coastal management policy and marine tourism development project for Korean coasts, especially for the South Sea of high development pressure, presenting sustainable tourism development policies for the future. To do so, it is examined central government-level coastal development projects set up by the Ministry of Culture and Tourism, the Ministry of Maritime Affairs and Fisheries and the Ministry cf Construction and Transportation, setting the direction of south coastal management and tourism development at a level of national territory planning. The problems of coastal management first and then the problems of the South Coast Tourism Belt Project are analyzed in order to present political and administrative alternatives. To overcome such problems and make Korea a marine tourism base in East Asia, there is a need for re-recognition of the value of the project and its continuous push through cooperation between central and local governments. Also, under the presupposition of consensus building among local people and the sustainable development of environments, there should be are-recognition that the future cf Korean marine tourism in the 21st-century and the success of an inverted $\pi-axis$ national development depend on the South coastal Tourism Belt Development Project.

Purpose: The purpose of this study was to investigate the effects of three-dimensional virtual reality horse riding simulator training using a head-mounted display on gait and balance in children with cerebral palsy. Methods: Ten children with cerebral palsy were randomly assigned to the horse riding simulator (HRS) group (n=5) or the horse riding simulator with virtual reality (HRSVR) group (n=5). To evaluate balance, center of gravity (COG) sway velocity and total sway distance of each group were assessed using the Wii balance board, and gait speed and stride length of each group were assessed using a gait analysis system. Results: Intra-group comparisons between pre- and post-intervention measures revealed that there were significant changes in all gait and balance variables such as stride length, gait velocity, COG sway velocity and COG sway distance in the HRSVR group (p<0.05). In the HRS group, there were significant changes in all variables except stride length (p<0.05). In addition, inter-group comparisons showed significant differences between the two groups in stride length, gait velocity and COG sway distance except COG sway velocity (p<0.05). Conclusion: The findings of this study suggest that horse riding simulator training combined with 3D virtual reality can be a new positive therapeutic approach for improving functional performance in children with cerebral palsy.

Maritime tourism destinations need to improve image as well as enhance competitiveness through development of new marine tourism attraction due to the decrease of the number of passengers. The maritime city is trying to combine dynamic marine leisure activities as an alternative. For this purpose, it is possible to realize clear marine tourism activation policy and improve the identity of local community through the accurate analysis of the interest of the stakeholder groups of local residents in Songjeong beach in Busan. In this study, we first analyzed the language network based on the expression language related to the conflict between the stakeholders of Songjeong beach. Second, we analyzed the individual characteristics of the structure of conflict frames of stakeholders and suggested solutions by comparing the differences and similarities between perception frames of conflict parties. Third, we distinguish and compare differences of perception among the conflict parties through the detailed frame type. Based on the relationship structure between the detailed frame types of the conflict parties, we suggested an alternative for conflict resolution by restructuring the conflicts and negative perceptions among the stakeholders.

Objective: The sitting and standing are motions that correspond to the previous stage of rehabilitation to go to walking for daily life. The purpose of this study was to measure task times, path length of the center of pressure (COP) and activity on the vastus femoris muscle using surface electromyography (EMG) when standing up and sitting down. Design: One group cross-sectional design Methods: Fifteen elderly subjects (8 male, 7 female) participated. All subjects were tested three times according to four assist levels (non-assist, lower, middle, and maximal assist) using adjusts the length of spring at sit-to-stand and stand to sit on a chair. The task duration, and COP path length were recorded for the balance function on the Nintendo Wii fit board. The activity of the rectus femoris muscle was recorded on both legs using surface EMG. Results: The results showed that the task duration of the sit-to-stand and stand-to-sit were significantly increased compared to without assist (p<.05). The activation of the rectus femoris muscle more significantly decreased compared to without assistance at standing or sitting (p<.05). Conclusions: The assistive chair showed less quadriceps muscle activation during sitting and standing compared to without assistance. We suggest that our assist-standing chair can help with activities of daily living such as standing up and sitting down movements adjusting the spring length for control assist level by safely.
