This research aims at analyzing the changes in residential environment after a residential environment improvement project focusing on the analysis into the physical environment of a residential environment improvement project, and examining in what direction the changes by residents' own efforts occurred after public support, such as infrastructure. The present residence development method has become different from the previous pulling down method and is focused on regeneration. By examining in what direction the target residence is being changed because of the development by residents' own efforts after the government's public investment at this time, this study also aims at investigating the direction to develop a guideline for residential improvement for later improvement of deteriorated residence. As for the contents of the analysis, changes in public support, such as infrastructure, and other areas after the residential environment improvement project were compared and analyzed from the land use, street system, and condition of buildings before the residential environment improvement project through field survey, geographic information system(GIS), registered land and building data and so on. The biggest change since the support from the government was that at the beginning of the project, the application of special provision of building laws and different financial supports led to lots of newly built buildings. Since then, their number has decreased rapidly, and in most cases, there have been some changes in part, such as changes in the use of land or repair of disposal tanks. Most newly built buildings were multi-household houses, and it has caused road capacity and parking lot capacity, etc., to be exceeded, which has worsened the pleasantness of the living environment. In addition, other problems have also appeared, for example, the lack of residence supporting facilities yet with a higher level of residential density. Regarding the changes in the residential environment after the residential environment improvement project, maintenance of houses were conducted in some degree as diverse alleviation policies to improve poor residence, yet the absence of the guideline for the direction of developing the whole district has made the residence environment more dense and deteriorated. To solve these problems, in advance to a residential improvement project, specific management methods based on short-, mid- and long-term plans for the direction of development by residents' own efforts and a sustainable guideline seem to be necessary.

Many people today suffer from stress originated from diseases, daily life, workplace, or environmental pollution. People want a comfortable and stable life along with physical and mental relaxation. As the number of people pursuing a comfortable life increases, terms of well-being and wellness have become more common, and wellness-related industries are also developing. Among the wellness and well-being industries, the wellness entertainment contents are one of the highest growing industries. This study aims to investigate how wellness contents contribute to improving the psychological well-being level of users through the mediating effect of telepresence in online. Specifically, this study suggests a hypothesized research model on the influence of online wellness entertainment content, which consists of sensory-, emotional-, and cognitive-attributes, on telepresence, followed by psychological well-being and word-of-mouth. With an empirical test using data on the experience of meditation app experience for 305 people, the result showed that the hypotheses in the research model were supported. The result of this study showed that wellness content induces users' telepresence and word-of-mouth, suggesting that wellness contents are needed to develop into a profit model rather than being limited to simple mental and physical stability.

The aim of this study was proceed for 6weeks to determine the effect of middle-aged women's upper lips ms by SUKI programs. A total of 20 subjects were tested, and the SUKI arbitration programs of Pattern T1, Pattern T2, Pattern T3, Pattern T4 were adopted three times a week in six weeks. The results were as this. It showed a significant difference in the EG, although some of the intra-group comparisons of the upper lip ms. Therefore, SUKI programs have been shown to help improve the elasticity of the upper lip ms(p<.05). In this study, the SUKI program was used based on the fact that although limited, the elasticity of the upper lip ms, located in the facial part of a middle-aged woman, causes various wrinkles around her mouth, making them lose confidence in their appearance. This also suggests that normal facial ms can affect the appearance of the female middle-aged woman, and it was intended to suggest some ways to manage the appearance by proper management of facial muscle according to the life cycle of the female middle-aged woman. In conclusion, we hope that in the future, various experiments will be used as new research data on how to prevent women's facial skin beauty and wrinkles and help improve elasticity of facial muscles around the mouth.

Care of people with severe disabilities requires care throughout their life cycle compared to non-disabled families. For this reason, carers of severely handicapped families are highly likely to have negative feelings throughout the family as well as daily stress. Disabled families also have a high rate of experiencing difficulties between non-disabled children or married couples in life centered on the disabled. In particular, the rapid aging in Korea affects the lives of the elderly disabilities along with the aging of the caregivers. The study explored alternatives to realistic support through the past and present experiences of caregivers with disabilities through qualitative research methods, and derived hopes and expectations for the future as follows.First, after confirming the disability for infants and toddlers with disabilities, information about the support system or system is provided from the rating agency. Second, providing "customized care support" suitable for the type of disability or individual characteristics at the social, political, institutional, and economic levels. Third, the provision of programs for non-disabled children and the provision of healing programs only for families with disabilities or those with disabilities. Fourth, the provision of spaces and programs that provide rest and rest for adults with disabilities. Fifth, the application of a long-term care system for the elderly reflecting the aging age of the disabled and institutionalization of community care for the disabled. The research is meaningful in that it presents discussion points for improving the quality of life of adults and the elderly with disabilities.

The study studied ways to improve the adjustment of the cadastral reform project after analyzing and evaluating the method of determining the boundaries and the overall status of the adjustment, focusing on cases of complaints in the business district in Sejong City, where the re-investigation project was completed. Measures to improve the adjustment amount of the cadastral reform project were largely divided into boundary adjustment and improvement measures according to the scope of area allowance and institutional improvement. According to an analysis of the status of boundary adjustment in Sejong City, the boundary of the cadastral reform project was being adjusted in various ways, and among them, it was found that it is simple to adjust, to formalize parcels, and that many adjustments are being made centering on resolving blind areas by establishing new roads. When setting such a boundary, it is necessary to establish an efficient and reasonable boundary by actively encouraging sufficient consultation with owners and an adjustment boundary that reflects the personal will of landowners to minimize disputes over the adjustment amount. In terms of improvement measures based on the area limit, it is necessary to accurately record and preserve the results of the cadastral resurvey in numerical data and to ease or exempt the adjustment amount if it is within the area permissible scope of the Spatial Data Management Act when calculating the adjustment amount. Finally, in relation to the adjustment, it was judged that it would be necessary to provide long-term low-interest loans to their own land to landowners, and that it would be necessary to calculate the adjustment through appraisal calculated by third parties fairly and objectively based on value judgment.

The study investigated the forest vegetation structure of Kongju National University Forests in the vicinity of Seokjangri-dong to provide the information needed for efficient use and management. It conducted a Z-M phytosociological vegetation survey in 60 quadrate plots in August 2019 and generated the actual vegetation map by analyzing the physiognomic community classification and mean importance value. The physiognomic community classification showed five vegetation community types: Quercus acutissima community, Pinus densiflora community, Quercus variabilis community, Pinus rigida community, and Quercus serrata community. The relative importance value in the Q. acutissima community was 31.4% for Q. acutissima, 9.6% for Prunus spp., and 9.0% for Q. variabilis. In the P. densiflora community, it was 24.9% for P. densiflora, 12.4% for Q. acutissima, and 11.5% for Q. serrata. In the Q. variabilis community, it was 25.3% for Q. variabilis, 9.8% for Prunus spp., and 8.5% for Q. acutissima. In the P. rigida community, it was 28.4% for P. rigida 28.4%, 10.0% for Q. acutissima, and 9.3% for P. densiflora. In the Q. serrata community, it was 27.0% for Q. serrata, 11.3% for Q. aliena, and 11.5% for Styrax japonica. The actual vegetation map based on the uppermost dominant species to identify the forest vegetation's spatial distribution characteristics indicated that the natural vegetation covered the most with 87.5%, the number of vegetation patches was 87, and the average area per patch was 1.46ha.

In today's IT environment where various pieces of information are distributed in large volumes, recommendation systems are in the spotlight capable of figuring out users' needs fast and helping them with their decisions. The current recommendation systems, however, have a couple of problems including that user preference may not be reflected on the systems right away according to their changing tastes or interests and that items with no relations to users' preference may be recommended, being induced by advertising. In an effort to solve these problems, this study set out to propose a Fuzzy-AHP-based movie recommendation system by applying the BRNN(Bidirectional Recurrent Neural Network) language model. Applied to this system was Fuzzy-AHP to reflect users' tastes or interests in clear and objective ways. In addition, the BRNN language model was adopted to analyze movie-related data collected in real time and predict movies preferred by users. The system was assessed for its performance with grid searches to examine the fitness of the learning model for the entire size of word sets. The results show that the learning model of the system recorded a mean cross-validation index of 97.9% according to the entire size of word sets, thus proving its fitness. The model recorded a RMSE of 0.66 and 0.805 against the movie ratings on Naver and LSTM model language model, respectively, demonstrating the system's superior performance in predicting movie ratings.

Ground Operations Command (GOC) has studied various methods using artificial intelligence (AI) in order to accomplish ground missions more effectively and to strongly respond to variable strategic situations with advancements in fourth industrial revolution technology. As the result of various literature reviews, PEST-7S-SWOT is considered the most appropriate methodology for promoting strategies and for task development. These procedures consist of three stages. Phase 1 is analysis of external environmental factors from applying PEST procedures. We analyzed external environmental factors to determine opportunities and risk factors. Phase 2 is the analysis of internal environmental factors from applying 7S strategies. We analyzed the current state of an organization to find strengths and weaknesses. Phase 3 is SWOT analysis. It is based on the opportunities and risk factors from Phase 1 and the strength and weakness factors from Phase 2. We derive promotional strategies and tasks through SWOT analysis. In this study, four strategies and 11 tasks were derived for GOC AI systems. Those are promotion of policies and systems, reinforcing organizations, building an AI base, increasing expertise and capabilities, and validating PEST-7S-SWOT methodologies.
