In TETRA(TErrestrial Trunked RAdio) standard, TMO(Trunked Mode Operation) communicates with the UE through the base station and it has a higher priority than DMO(Direct Mode Operation) which communicates with UE directly for channel allocation. As a result, the UE needs an algorithm which restricts the frequency allocation by TMO so that DMO can have a successful communication within the network. However, the TETRA DMO standard does not consider this issue. In this paper, we propose an active DMO channel selection algorithm which allocates a channel based on some additional information such as channel usage state of TMO and channel utilization of DMO. The experimental results show that the proposed algorithm outperforms existing DMO channel allocation scheme in terms of the transmission efficiency.

The purpose of this paper is to critically investigate John McDowell's naturalism, and propose an alternative direction of inquiry in order for his naturalism to have a more explanatory cogency. McDowell's main project is to settle a philosophical anxiety that has made traditional philosophy waver between mind and world. If one stands on the world side, he would appeal to "the unintelligible given," and on the other hand, if one stands on the mind side, he would fall into anarchistic relativism. In order to relieve the traditional philosophical anxiety, what McDowell has in mind is to reintroduce an empiricistic intuition into a pragmatic conceptual setting. Although McDowell is successful in that it could avoid methodological difficulties with which traditional philosophy has faced, his discussion seems to give rise to a charge of "the Myth of the Given," presenting perceptual judgement as a model of judgement. I propose that McDowell has yet to account for the relation between perceptual and abstract judgements in a more cogent way, which has been far better explained by the experientialist account of the nature and the structure of the embodied experience.

Purpose: The purpose of this study is to clarify the social stigma phenomenon in teachers' perceptions and attitudes toward students who are classified as mental health support needs students in middle and high schools. Methods: Qualitative research was conducted through in-depth interviews and observations of 17 teachers and 2 consultants from 2 middle and high schools in Green City, which were evaluated as successful among the six pilot project schools designated by the Ministry of Education in 2013. The study's analysis is based on Hatch's hermeneutical method. Common categories were developed from the interviews and observations. Then, inferences were made per category and given importance to draw conclusions and lessons. Results: Teachers had a strong stigma in their perceptions of and attitudes to special needs students. Their perception was that those students are bound to go wrong due to family problems, even some having difficulty breathing, and that it's beyond their limit to help them. In addition, their attitudes included stereotypes, favoritism, punishment, and referral to experts. As a result, teachers did not expect those students would be cured or change and showed passive attitudes while shifting the responsibility to families and experts. Conclusion: This study is meaningful in that it showed the limitations of the role of teachers regarding mental health support needs students from the perspective of the teachers themselves. Today, when students' mental health problems are emerging as a serious issue, it is necessary to provide support to improve teacher's awareness and capabilities regarding adolescent mental health problems. In addition, we suggest the current selective policy that sorts out special needs students and provides care for them to evolve into a universal policy that improves public awareness and focus on prevention.

Considering the high needs of recipient countries and the regional biases of Korean Official Development Assistance (ODA) policy, increases in the total amount of ODA and allocation to the forest sector are needed for Central Asia. In Tajikistan, illegal harvesting and grazing cause a gradual decrease in forest area. The Tajikistan government conserves forests by requesting international cooperation and establishing a policy for sustainable management of forest resources and prevention of further damages. To suggest suitable strategies and plans, the current statuses of forests and forestry were investigated, and ODA projects that can illustrate successful Korean experiences of forestation were conceived based on various geographical features and local conditions of Tajikistan in this study. Forest resource creation type projects (fuelwood and Tugai forest restoration) could result in energy independence and enhancement of ecosystem service such as a climate regulation and an increase in biodiversity. Community development type projects (introduction of ecotourism, agroforestry, and planting of fruit trees) can contribute to job creation and encourage participation of local residents, thus improving their incomes. In addition, establishment of a project foundation, including education, training, and a national forest inventory, would help those projects be sustainable in the long-term.

The disaster and safety R&D budget has continued to increase since 2008, but the fire safety R&D budget is a small part. Therefore, successful outcomes that could lead to the economic growth of the fire safety industry have not been achieved. This paper suggests a fire safety R&D budget expansion, reinforcement of R&D capacity, and performance growing plan by analyzing the factors that affect the performance of a fire safety R&D project. Empirical analysis was performed through one-way ANOVA and regression analysis using the statistical program, SPSS statistics 21.0. As a result, this study suggests that the continuous expansion of R&D funds and the securing of excellent trained research manpower will be necessary to obtain qualitatively superior patents and papers.

Objectives This study aims to investigate the effect of the Korean medicine in treating dysmenorrhea as a part of school health program (SHP) and satisfaction rate of the participated students in this program. With this study, we tried to contribute to the development of health promotion program of Korean medicine. Methods As part of the 'Korean Medicine Health Promotion Project', we conducted a dysmenorrhea program at one of many high schools in Eumseong-gun. From April to June 2018, we conducted the promotion program a total of 7 times and analyzed the questionnaire regarding satisfaction and the monthly experience of menstruation. Results The study participants' grade distribution was $2^{nd}$ grade 32, $3^{rd}$ grade 23 with a total 55 students. Mean dysmenorrhea VAS was $6.07{\pm}2.10$, and the mean number of visits to the dysmenorrhea program was $3.61{\pm}1.47$. There were no significant differences in the average number of visits between grades. Overall satisfaction was $4.06{\pm}0.97$, teacher satisfaction was $4.29{\pm}1.10$, and lecture satisfaction was $4.18{\pm}0.95$. Dysmenorrhea decreased but was not statistically significant. Conclusions Korean medicine is appropriate for the health promotion program. With cooperation and support from local schools, it will be very possible to carry out a successful business. It is also necessary to organize the program according to the viewpoint of youth and to interact with the students.

National industrial complexes, airports, and seaports are major logistics nodes and the availability of their logistics services is a key factor for the successful operation of entire supply chains. For this reason, the central government has established a plan for their development and is investing in development projects. However, some difficulties exist in project prioritization and investment plan creation owing to the absence of a clear appraising method. For a smooth flow of national logistics and efficient investment on facilities, it is necessary to diagnose the logistics facilities' present conditions and practice sustainable management. In this study, a diagnostic method for logistics services, which consists of service factors and facility factors, is proposed. Adopting the method, facility factors can be prioritized to improve facilities' services; further, a standard procedure is proposed to support decision making for effective investments in logistics facilities. The method is applied to actual logistics facilities (three national industrial complexes, three seaports, and two airports) and the results indicate that it can be effectively applied to actual logistics facilities.

The social problem-solving R&D is different from the goal and process in comparison with research aimed at scientific excellence and industrial innovation. It pursues social values and active participation of the end-user civil society. In this study, we try to derive its characteristics by analyzing the cases that are evaluated as successful social problem solving R&D project. In order to analyse the social problem-solving R & D case, these four variables are selected; 1) social and technological planning for problem solving 2) participatory technological development 3) law, system and delivery system development for innovation deployment 4) scale-up of new R&D process. Those are important issues identified through case studies: 1) the tools and support services needed to carry out social and technical planning effectively, 2) the role of the Living Lab to coordinate opinions with experts and users, 3) the legislative and institutional improvement activities as important as technological development, 4) researcher's change through interaction with end user.

The urban regeneration project is an activity that promotes the economy in underdeveloped commercial or residential areas and maintains urban communities through improvement of living in residential areas. Through this study, various successful cases of urban regeneration at home and abroad and surveys related to urban regeneration in Bongsan Village, Yeongdo, Busan were collected and analyzed. Key keywords for each case were derived, grouped, and top keywords were created. The 13 top keywords were evaluated using Likert's 5-point scale, and AHP was conducted for the 10 keywords that were finally selected. As a result of AHP analysis, the preference for "spatial and physical properties" was derived in the order of "publicity", "sustainability", and "identity". The preference of "content and system properties" was derived in the order of "resident participation", "convenience", "locality", and "local government participation". It is necessary to present a role as a design guideline for establishing urban regeneration designs in relation to various urban regeneration projects that will become more active in the future through the analysis of preferences of urban regeneration keywords derived through this study.
