The purpose of this study is to analyze how video media such as movies and dramas, which aim for one-way and viewing-oriented content, remediates the attributes of games, and to study the influence and convergence of games and video media. There were two main types of game culture convergence patterns of video media. The first is the passive fusion of the content aspect of the game, and the second is the active fusion of the system aspect of the game. Such research is significant as a basic study that reveals that games affect various video media and proves that game media can function as a representative media leading popular culture.

This study was carried out to provide basic data. his research conducted the survey using face to face survey and board survey during about 2 months from Oct. to Nov. in 2009 for users of Bongje Mt., a small-sized mountain at downtown, and Acha Mt., a big-sized mountain at outskirt so as to compare the differences of using behavior by forms and size of urban forest in living area of Seoul. Characteristics of urban forest users, using behavior, demands and satisfaction of facilities and management and pass pattern were set as research items. The thing in common for using behavior is that both genders of main users were in more than 40s~60s. They showed the highest using rate from 7 a.m. to 12 p.m. and high rate for using nearly everyday or visiting two or three times per a week. In addition, it's judged that the accessibility from dwelling area to entrance of urban forest in living area is good and satisfaction for the standard of facilities and their management in forest way was relatively low. For the complement and essential facilities, 'sanitary facilities' showed the highest rate. For the differences of using behavior, most of Bongje Mt. users were residents living within a 2km radius (under the standard of walking) and they moved by average 1.3km. And, they preferred short-time activities of about 24 minutes. On the other hand, main users of Acha Mt. were residents living within a 4km radius (under the standard of walking) and people of other regions. and 60% of them preferred the passage route taking 3hours half over 6km. Through the survey on using behavior of urban forest in living area of Seoul, with different using form and forest size, introduction of using program for main users or managing method of differentiations for introduced facility's management should be properly applied. Especially, urban forest should be systematically managed like park green as expected that residents's using of urban forest will be increased with the increase of leisure time.

Recently, hierarchical architectures of databases for location management have been proposed in order to accommodate the increase in user population in future personal communication systems. In particular, a 3-level hierarchical database architecture is compatible with current cellular mobile systems. In the architecture, a newly developed additional databases, regional location database(RLR), are positioned between HLR and VLRs. We propose an efficient cache scheme, called the Double T-thresholds Location Cache Scheme. The cache scheme extends the existing T-threshold location cache scheme which is competent only under 2-level architecture of location databases currently adopted by IS-41 and GSM. The idea behind our scheme is to use two pieces of cache information, VLR and RLR serving called portables. The two pieces are required in order to exploit root only locality of registration area(RA) but also locality of regional registration area(RRA) which is the wide area covered by RLR. We also use two threshold values in order to determine whether the two pieces are obsolete. In order to model the RRA residence time, the branching Eralng-$\infty$ distribution is introduced. Our minute cost analysis shows that the double T-threshold location cache scheme yields significant reduction of network and database costs for molt patterns of portables.

In an era of population decline, depopulated regions facing challenges in attracting inbound population migration must enhance urban vitality through the attraction of living populations. This study focuses on Busan, a city experiencing population decline, comparing the spatiotemporal distribution characteristics of registered residents and living populations in various administrative districts (Eup-Myeon-Dong) using mobile communication big data. Administrative districts are typified based on population change patterns, and regional characteristics are analyzed using indicators related to urban decline and vitality. Spatiotemporal distribution analysis reveals generally similar density patterns between registered residents and living populations; however, a distinctive feature is observed in the city center areas where the density of registered residents is low, while the density of living populations is high. Divergent trends in spatial patterns of change between registered residents and living populations show clusters of registered population decline in low-density areas and clusters of living population decline in high-density areas. Areas adjacent to declining living populations exhibit large clusters of population changes, indicating a spillover effect from high-density to neighboring areas. Typification results reveal that, even in areas with a decline in registered residents, there is active population influx due to commuting or visiting. These areas sustain an increase in the number of businesses, confirming the presence of industrial and economic growth. However, approximately 47% of administrative districts in Busan are experiencing a decline in both registered residents and living populations, indicating ongoing regional decline. Urgent measures are needed for enhancing urban vitality. The study emphasizes the necessity of utilizing living population data as an urban planning indicator, considering the increasing limit distance of urban activities and growing interregional interaction due to advancements in transportation and communication.

This study was carried out to draw up the planting plan of bridge type ecological corridor for animals migration at Hakgogae(ridge) destroyed by road construction in Yongin, Gyeonggi-do, South Korea. It was conducted with two steps, survey and planting master plan. We surveyed the structure of topography, plant community, and animal habitat. We also selected the target species migrate ecological corridor and suggested a concept of each planting area, the planting species, and the planting density based on the analyzed data and finally drew up the planting plan. The structure of topography was a steep slope due to the mountain ridge destruction so the bridge type ecological corridor was could be applied in this study and we supposed that the animals migrate along the both edge of corridor. As the results of analyzed plant community structure in two sides, the dominant woody species, Quercus serrata and Q. variabilis were distributed on the bottom and the belly of a mountain, while Pinus densiflora community was distributed on the mountain ridge as edaphic climax. The similarity between Q. serrata -Q. mongolica -Q. variabilis community on the West of survey site and Q. serrata -Q. mongolica community on the East of survey site was high in 71.0 percentages. As the results of surveying birds and some mammalia, seven species and fifty-seven individuals of birds were founded in survey area, and two species and two individuals of rodents were founded. We selected birds and some mammals for the migration species that supposed to migrate ecological corridor in drawing up the planting plan. And then we divided the planting areas into bird corridor and habitat, and mammals corridor, also suggested the planting areas in detail as follows: community planting area of shrub at slope adjacent to the bridge exit as a buffer zone, screen planting area, community planting area of herb at steep slope connected with mountain areas, inducement planting area of the animals, community planting area for bird migration, community planting area for mammals migration, and community planting area for bird habitat. We selected the planting woody species which were the constancy ratio based on the analyzed data of plant community around mountain areas was high, and suggested the planting master plan each space.

This study focuses on the right to self-determination, which has a higher possibility of infringement on rights, for people with developmental disabilities, who are more vulnerable to rights protection than other types of disabilities, and seeks to obtain implications of the basis for academic discussion and practical strategies. To this end, data were collected through a structured survey on 302 social workers in Seoul, Gyeonggi, and Gangwon area to identify the importance and execution degree of self-determination components of the developmental disabled, and descriptive analysis, differences. analysis, matrix analysis was applied. As a result of the analysis, the importance and performance degree were evaluated at an absolute level lower than the positive level, and the overall average standard execution degree was found to be applied relatively later, and the difference between the two levels was statistically significant. Meanwhile, goal setting and achievement, self-management and regulation, branch recognition and perception, etc. were identified as under-action elements as disparity between importance and performance. Therefore, in order to improve the balanced positivity of social workers and people with developmental disabilities in consideration of the reciprocity of human rights protection, applied behavior analysis, positive behavior support, and individualized service plan based on the application of a person-centered program and self-determination improvement program are applied. Suggestions were made on detailed strategies such as accounting.

This study examines how path dependency of working poor labor market segmented from the primary and the secondary labor market affects employment and quality of employment of working poor. It Further examines how path dependency makes working poor to remain in the labor market and makes it difficult for them to escape from a vicious poverty cycle. Data is based on the $3{\sim}7th$ Korea Labor and Income Panel Study(KLIPS). Markov's transition probability and discrete-time hazard analysis are used for analysis. This study finds that Korea labor market is divided into three parts; the primary labor market, the secondary labor market and the working poor labor market. The proportion of employed poor has been reduced, but the proportion of non economically-active working poor has been increased and has become the main group among the working poor. This shows that labor demand of working poor is fundamentally lacking and there are structural barriers that block working poor's employment itself. The regression analysis shows that the longer working poor labor market participation is, the lower poverty-exit rate. This is an evidence of vicious poverty cycle that the poor have little chance to exit from working poor labor market, once they step into it. Therefore, the longer their participation in poor labor market, the more likely they would move only within the closed working poor labor market. Consequently, it is necessary to fundamentally reform labor market structure and to alleviate negative perception and discrimination about the poor labor while activating labor demand.

This study investigated the effects of different types of shouting actions on the strength of the human body. Both H-reflex and MVIC measures of the rectus femoris muscle were used to investigate effects on impact force and motor performance, in order to find optimum shouting methods. The H-reflex of the soleus muscle gave an electric stimulus to the curve of the knee that contains the tibial nerves. Surface electromyelography was used to collect muscle activity the amplitude increased 28% at action with shouting and 29% at the one immediately after short-time shouting than the one without shouting was. To assess the myoelectric activity of the rectus femoris, a surface electrode was attached to the right side of the lower extremity and to increase 10% and 1% depending upon shouting type. The findings were as follows. Shouting affected not only motor efficiency (H-reflex), but also the amplitude of MVIC, with a positive effect on increased muscle strength. Further comprehensive studies are needed to investigate the many variables of increased muscle strength for general purposes, for instance, shouting and breathing, brain waves, and so on.

The white cane, walking assistive device of visually impaired person, has disadvantages for acquiring the information by contacting obstacles directly and detecting low obstacle on the ground. Recently, new devices have been developing to solve these problems, but these were not widely used due to high price and appearance. Therefore, in this study, we developed two types of walking assistive shoes which were manufactured with infrared sensors, pressure sensors and vibrating motors. Two types of shoes were classified with single sensor (SS) and double sensor (DS) type according to the number of infrared sensor. To evaluate the effectiveness, we compared required time and number of collisions during walking with walking assistive shoes and white cane on obstacle area. As the results, required time was increased than white cane while number of collisions was decreased when walking with developed walking assistive shoes. In addition, required time and number of collisions was more reduced when using walking assistive device than white cane. Therefore, we suggests that developed walking assistive shoes can a great help to provide safe walking condition and reducing time to adapt new types of walking assistive shoes.

The local identity of a female marriage migrant is not fixed to certain boundary or location, but rather comprised flexibly according to geographical movement or new settlement to different place. This research focuses on the local identity and life change of female marriage migrants that are constituted/reconstituted according to spatial transition, or migration. The analysis was conducted to find out traits of changes in the periods of migration and settlement based on the following categorization: multiculturalism and bicultural identity, assimilation and host country identity, exclusion and origin country identity, marginalization and marginal identity. The results are as follows; while having identical experience in terms of a migration, the local identities of marriage migrant women differed according to individual/regional characteristics as well as their respective roles within those traits. In addition, most of females showed passivity in maintaining and exposing their cultural identities of original states. Moreover the life satisfaction change of female marriage migrant that is type of assililation and host country identity is appeared more than others. through this assimilation and accommodation mean adaptation to female marriage migrant lived in Korea. However the intercultural competences of both marriage migrant woman and children in multicultural families facilitate the connection among different cultures. Based on these outcomes, with the transition to multicultural society and space, this research proposes the necessity of fostering global citizenship for mutual recognition of each culture, thus enabling coexistence.
