Screen Golf provides a more realistic interface to users by implementing sophisticated sensors and 3D graphics so that they can play golf in an environment almost identical to the actual golf course, to provide a sense of reality that goes beyond simply enjoying golf indoors. In addition, users who experienced this interface environment showed a tendency to feel the fun of golf more and become more immersed in golf. Therefore, it is most important to provide an effective realistic interface in screen golf. In this study, the meaning of screen golf as a tangible sport and various interface elements embodied in screen golf were summarized. Also the factors that enable users to feel reality and fun of actual golf to make users more immersed in screen golf were identified. For this, interface elements based on sensory elements were arranged in terms of visual, auditory, and tactile sense, and improvement plans and directions for providing effective sensory interfaces for screen golf were suggested through user FGI, targeting regular customers of Golfzone and KakaoVX screen golf, and in-depth interviews with experts. As a result of the analysis, it was confirmed that the course information including the yardage and the play situation-directed graphic are elements that make immersion in the visual aspect. In terms of tactile aspect, the fact that users actually use golf equipment, as well as the sense of existence of a physical interface that embodies various course environments and course setting appeared to be an important factor. In particular, in the auditory aspect, it was confirmed that providing customized services for each user through AI caddy implemented to resemble a actual caddy is the most effective way to immerse users in screen golf with greater fun and realism.

Objective : Purpose of this study is to discuss benefits and implications of the clinical reasoning process and re-evaluation in the OTIPM by introducing a single case that occupational therapy intervention is provided based on the OTIPM. Methods : The case subject is a boy aged 5 years and 10 month who had diagnosed as attachment disorder and anxiety disorder from a pediatric psychiatrist before. The boy is referred to sensory integration therapy clinic and underwent occupational therapy intervention service twice a week for four month. Therapeutic activities for the intervention were consisted of sensory integration activities for restorative model, care-giver education for educational model, and performance skill training for acquisitional model. Measurements used in the initial evaluation are JSI-R, DDST-2, Social Maturity Test, KPPS-R, and observation-based performance task analysis. For the performance task analysis, performance skill items were constructed based on the Occupational Therapy Process Framework (OTPF), and those were assessed by the evaluation system of Assessment of Motor and Process Skill (AMPS) and Evaluation of Social Participation (ESI). Results : The detail process of implementing of the OTIPM in this study is reported by following four phases; 1) establish client-centered performance context; 2) establish baseline and interpret cause (initial evaluation); 3) intervention planning and implementing; and 4) recognize intervention outcome (reevaluation). Conclusion : In this case, occupational therapist could provide the client an occupation-based intervention within comprehensive performance context based on the OTIPM. Therapist could clearly identify the cause of problematic performance skills and behaviors and so provide effective intervention to improve client's occupational performance. Additionally, it was found that client's satisfaction of the intervention can be raised when the concept of 'who is the client' is expanded based on the OTIPM. From this study, it is proposed that OTIPM may be a model educible 'comprehensive' enhancement of 'specific' occupational engagement, as it considers both improvement of occupational performance and satisfaction.

Cultural welfare is the cultural activity provided and supported by state, a local autonomous entity, and private organizations to improve the quality of people's life. And as a basic concept as well as a premise of discussion on cultural welfare, cultural right is a social right, a right which can make cultural express, gain access to cultural activities. A statue concerning cultural activities contributed to the promotion of our people's cultural welfare interwoven with cultural right. But laws were made for the purpose of enforcing national policy and supporting regime rather than promoting fundamental human rights, and they became effective and were understood as a mere part of national government, not as perspective of their execution, security of right or realization of them. On the other hand, based on laws concerning social welfare, cultural life means human life consisting of minimum welfare system, and minimum level of life which guarantees least cultural life is becoming an objective standard. This means the standard level of cultural right, and for the handicapped cultural rights are concretely guaranteed as a right in that they will not be discriminated for their approaching to cultural activities. However, laws concerning cultural activities have limitation in that there are ambiguous concept and limitation of cultural life, and there are no concrete and active laws about cultural rights to guarantee cultural life. In a constitution and laws concerning social welfare, cultural welfare must have concrete contents about the range and the level of cultural rights. In order cultural rights to be turned into complete ones which can assert its rights, as seen in the Supreme Court, a court has to try to understand the violation of cultural rights as the violation of legal rights.

In this study, we analyzed the teaching practices of science teachers using smart technologies and investigated their difficulties in implementing smart education and their educational needs. We also studied their opinions on the application of smart technologies in science education. The participants were seven science teachers who participated in the smart education study group of a science teacher association in Seoul. We elaborated on the characteristics of smart education in science education during comprehensive analyses of instructional materials used in science classes and the initial interviews. We then analyzed the second interviews by categorizing their responses inductively. All the science teachers used the 'instant access as needed', but their interactions, simply answering students' questions, were found to be at a low level. They did not effectively use the 'collaborative interaction with SNS or wiki-based service' for the support for interactive learning. While most collected learning results of their students and provided feedback in the aspect of 'individualization according to leaner level', they were not aware of 'context, situation, and location of learners' in smart education. While all the teachers extended learning opportunities by using learning resources widely in smart education, most were not aware of 'support for self-directed learning'. Most teachers believed that smart education should be developed to help students learn interactively and in a self-directed manner. They also provided many opinions on teacher training programs and environmental support for smart education. Based on the results, some considerations for implementing smart education in science instructions effectively are discussed.

Travellers consider extra travel time to be arriving their destination because of uncertainty of travel. So it is important to make predictable highway by providing information of travel time variability to traveller so as to enhance level of service at highway. In order to make predictable highway, it is necessary to develope measures of travel time variability that travellers can easily understand. Recently advanced country including the United States, travel time variability index are actively studied. In earlier study, 95percentile of travel time is considered to be most important calculation index of travel time variability. In this study, is has focused on the propriety analysis of 95percentile of travel time in domestic transportation environment. Result of analysis, All of measures(80percentile of travel time, 90percentile of travel time, 95percentile of travel time) show the tendency to increase when case of weather factor occur compare to normal condition under LOS A~D. Especially 95percentile of travel time increased sensitively.

In this study, main focus was analyzing whether the retired middle-aged people's life style and personal characteristics affect house selection attributes and there are any differences according to their life styles. The finding and implications of this study were as follows. The middle-aged people were trying to pursue leisurely and healthy life. Therefore, they prefer the high service quality of health, medical facilities, culture, leisure, and entertainment facilities. These trends were caused by the expansion of the five-days working styles, the improvements of the smart consumptions, the high levels of the education, and the high social and economic participations of the females. The overall changes in social, cultural, economical circumstances made them different from other generations. Also current middle-aged people were more challenging and active and they thought themselves young compared with the people of the older generation. In the future those middle-aged people's life style will be more diversified. Therefore new housing plans are necessary for the middle-aged popple to satisfy their diverse housing needs and housing circumstances. Based on the results of this study for the middle-aged people's life style and housing selection attributes after their retirement, more studies are necessary in new and different views. Furthermore diverse house supplies, housing marketing, housing policies should be provided for the middle-aged people for their retirement and need to study more their future housing satisfaction and their housing needs.

Cloud computing markets are rapidly growing as cost savings and business innovation are being carried out through ICT worldwide. In line with this paradigm, the nation is striving to introduce cloud computing in various areas, including the public sector and defense sector, through various research. In the defense sector, DIDC was established in 2015 by integrating military, naval, air and military computing centers, and it provides cloud services in the form of IaaS to some systems in the center. In DIDC and various future cloud defense systems, It is an important issue to ensure availability in cloud defense systems in the defense sector because system failures such as network delays and system resource failures are directly linked to the results of battlefields. However, ensuring the highest levels of availability for all systems in the defense cloud can be inefficient, and the efficiency that can be gained from deploying a cloud system can be reduced. In this paper, we classify and define the level of availability of defense cloud systems step by step, and propose the strategy of introducing Erasure coding and failure acceptance systems, and disaster recovery system technology according to each level of availability acquisition.

The purpose of this study is to investigate the moderating effect of home-based welfare facilities for older adults on the associations between the activities of daily living (ADL) / instrumental activities of daily living (IADL) and the depressive symptoms among Koreans in later life. Multilevel analysis was conducted with Korean Longitudinal Study of Aging 5th data and the public report about welfare facilities from Ministry of Health and Welfare in Korea. Samples were 4,139 older adults over 65 years old. The dependent variable was depressive symptoms, and individual level independent variables were ADL and IADL. The ratio of home-based welfare facilities out of 10,000 older adults in each city and province was the moderator. As a result, the effects of ADL on depressive symptoms vary according to the proportion of elderly welfare facilities out of the old population in the community. In specific, the older adults who live in the place where the elderly welfare facility rate was higher were less affected by ADL. Also, the more IADL people had, the more depressive symptoms they had. However, the interaction effect between IADL and the proportion of home-based welfare facilities was not significant. It suggests that delivering welfare services helping ADL through the home-based welfare facilities may be useful for decreasing depressive symptoms. Moreover, considering the proportion of facilities and older population will be helpful to make the welfare facilities efficiently work.

Potholes on the road directly affect drivers' safety, satisfaction, and vehicle damage. Thus, real-time detection and response are required. Increasing frequency of patrols allows for potholes to be detected and responded to quickly, but this takes much manpower, money, and time. In addition, potholes have different occurrence characteristics depending on the rain conditions, so it is necessary to consider the optimal frequency from an economic and road-service perspective. Therefore, a quantitative analysis was done on the effects of rainfall on the occurrence characteristics of potholes. Information on the persistence, impact of rainfall intensity, and weather information was collected over a long period. Based on the results, a risk-based, optimized, and changeable road-patrol strategy is presented. The analysis results show that the probability of pothole occurrence increases by 2.4 times in rainy weather. Furthermore, the impact continues for 3 days even after the rain stops. The probability of pothole occurrence increases by 0.46% per 1 mm of rainfall, and the occurrence characteristics react sensitively to even a small amount of rain of around 1 mm. It was concluded that road patrol is required at least once every three days for an effect-free period, while twice a day is needed for the "sphere of influence" period to achieve a 95% reliability level.ys for effect-free period, while twice a day for sphere of influence period to satisfy 95% reliability level.

The purpose of this study was to examine the impact of climacteric women's attitude to developmental phenomena and their menopausal symptoms on their meaning of life in an attempt to provide some information on the improvement of climacteric women's quality of life. The subjects in this study were 313 women who resided in different regions involving a large city D and another city C. They were aged between 40 and 60 and were going through their menopause. They were aged between 40 and 60 and were going through their menopause. The subjects were selected by convenient sampling, which was one of nonprobability sampling methods. The collected data were analyzed by the statistical package SPSS. The major findings of the study were as follows: First, the climacteric women didn't take a positive attitude toward developmental phenomena. They occasionally suffered severe menopausal symptoms, and they didn't find a great meaning in their life. Second, the climacteric women found a more meaning in their life when they took a more positive attitude to developmental phenomena, and those who underwent severer menopausal symptoms found a less meaning in their life. Third, the climacteric women's meaning of life was under the influence of their attitude toward developmental phenomena and menopausal symptoms. Specifically, their attitude to menopause and mental symptoms had a large impact on that. Given the findings of the study, social welfare intervention should be provided for climacteric women to promote their physical health related to menopausal symptoms and psychological health related to attitude toward developmental phenomena to find a more meaning in their life. Besides, local welfare centers should be open to climacteric women as one of governmental policies so that they could lead a healthy life. Education should be provided for them to be ready for their own menopause, and social welfare counseling service should be offered from diverse angles
