역사적으로 국제연합(United Nations)은 해방 이후 대한민국 정부수립을 지원해 주었고, 한국전쟁시 평화유지군을 파병하여 자유민주주의와 평화를 수호하는데 결정적인 역할을 하였다. 유엔의 정치적·군사적 지원을 바탕으로 대한민국은 오늘날 세계 10위의 경제대국으로 성장할 수 있었으며, 이제는 중견국으로서 국제사회의 평화와 번영에 기여하기 위해 책임과 역할을 다해야 할 시점이 되었다. 유엔의 국제평화활동은 분쟁의 예방과 평화조성, 평화강제, 평화유지, 평화건설을 아우르는 포괄적 개념으로 유엔헌장(UN Charter)에 근거하여 안전보장이사회 결의안에 따라 시행된다. 탈냉전 이후 국제 안보환경과 분쟁요인의 변화에 효과적으로 대응하기 위해 유엔은 2000년 브라히미 보고서와 2015년 유엔평화활동에 관한 고위급 패널보고서를 통해 국제평화활동의 패러다임 전환을 추진했다. 따라서 본 연구에서는 아직까지 재건지원과 인도적 지원 등 제한적 수준에서 참여하고 있는 한국군의 국제평화활동을 평가하고 향후 중견국으로서 보다 적극적인 참여를 위한 발전방안을 제시하고자 한다. 이를 위해 유엔 평화유지임무단이 다수 주둔하고 있는 아프리카 대륙을 중심으로 지역분쟁의 역사와 특수성, 탈냉전 이후 변화된 갈등요인, 유엔 평화활동의 새로운 패러다임을 고찰하였고, 향후 한국군이 지향해야 할 국제평화활동 발전방안을 제시하였다.

Background: The radionuclides released by the Fukushima Daiichi Nuclear Power Plant (FDNPP) accident 9 years ago are still being monitored by various research teams and the Japanese government. Comparison of different surveys' results could help evaluate the exposure doses and the mechanism of radiocesium behavior in the urban environment in the area. In this study, we clarified the relationship between land use and temporal changes in the ambient dose rates (air dose rates) using big data. Materials and Methods: We set a series of 1 × 1 km² meshes within the 80 km zone of the FDNPP to compare the different survey results. We then prepared an analysis dataset from all survey meshes to analyze the temporal change in the air dose rate. The selected meshes included data from all survey types (airborne, fixed point, backpack, and carborne) obtained through the all-time survey campaigns. Results and Discussion: The characteristics of each survey's results were then evaluated using this dataset, as they depended on the measurement object. The dataset analysis revealed that, for example, the results of the carborne survey were smaller than those of the other surveys because the field of view of the carborne survey was limited to paved roads. The location factor of different land uses was also evaluated considering the characteristics of the four survey methods. Nine years after the FDNPP accident, the location factor ranged from 0.26 to 0.49, while the half-life of the air dose rate ranged from 1.2 to 1.6. Conclusion: We found that the decreasing trend in the air dose rate of the FDNPP accident was similar to the results obtained after the Chernobyl accident. These parameters will be useful for the prediction of the future exposure dose at the post-accident.

본 논문은 노약자들의 발목근력보조를 위한 착용형 로봇에 대해서 서술하였다. 기존 착용형 로봇들은 보행 시 필요한 근력을 보조하기 위해 대부분 모터와 감속기를 사용하였다. 하지만 모터와 감속기의 조합은 무게가 무거울 뿐만 아니라 감속기 치차의 마찰때문에 실제 사람의 근육과 달리 강성과 토크를 동시에 제어하기 어려운 한계가 있다. 따라서 본 연구에서는 모터/감속기 조합보다 가볍고 안전하며 근력을 보조하는 힘을 충분히 발휘할 수 있는 Mckibben 공압 근육을 사용하였다. 발목의 피칭 모션에 이용되는 종아리 가자미근 및 앞정강근의 힘을 한 쌍의 공압 근육을 사용한 상극구동으로 보조하였으며, 상극구동제어를 위해 상극구동 모델 파라미터들을 실험적으로 도출하였다. 사용자의 보행의지를 판단하고자 발바닥에 부착된 압력변위센서로 압력과 압력중심위치를 측정하여 발바닥의 하중과 발목토크를 계산하였고, 이를 기반으로 공압 근육 관절의 강성과 토크를 동시에 제어하였다. 최종적으로, 트레드밀에서 근전도 신호를 측정하여 발목근력보조로봇의 성능을 실험적으로 입증하였다.

Interim measures by an arbitral tribunal aim to protect the parties' rights before or during arbitral proceedings for avoiding frustration of the final award in international commercial disputes. Even though decisions of the interim measure are expected to be performed by parties directly during the arbitral processing, it is not easy to be provided by the arbitral tribunals cause of lack the power to enforce their decisions directly against the parties. Particular court supports mechanism for enforcement directly to assistance to arbitral tribunal's decisions. Decisions on interim measures are provisional. Even though the arbitration is ongoing to request interim measure directly to the arbitral tribunal, relevant courts are able to ensure effective relief cause by the difficulty of limited rights of the arbitral tribunal. In this time both revised Korean Arbitration Act in 2016 and UNCITRAL 2006 revised Model Law are complemented to attach articles for recognition and enforcement of interim measures by arbitral tribunal during the arbitration processing. It could be possible to enforcement of decisions of interim measures by arbitral tribunal on the revised arbitration law. In this paper it is considered the problems and alternatives on related applicable articles and articles of recognition and enforcement for the interim measures by arbitral tribunal under the revised UNCITRAL Model law and Korean Arbitration Act.

The study aims to analyze the adaptation strategies and resilience of tobacco farmers to face unfavorable trading system. The research method refers to a qualitative approach with phenomenological models and case studies. The findings revealed tobacco farmers in Jember developed various adaptation strategies and resilience through farmer group organizations, partnerships, self-capacity building and access to financial institutions based on economic, social, cultural, and experience values from various sources and interactions among fellow tobacco farmers. The tobacco trading system, which is left to the market mechanism, results in low bargaining power of farmers, this encourages tobacco farmers to develop various adaptation and survival strategies, namely through collective activities of farmer groups, partnerships and self-development and access to financial institutions. Dealing with the unfavorable tobacco trading system, tobacco farmers do not switch to other commodity farming but adapt and make Jember a center for tobacco production in East Java and Indonesia. From this findings, it suggests to the government as the regulator does not only provide subsidies for tobacco farmers, but also must provide various technical assistance to increase the ability of tobacco farmers. More importantly, regulations must be made benefit tobacco farmers other than corporations so that equality can be enjoyed by tobacco economy players.

Recently, Vertical-Closed Loop system using geothermal which is the most efficient among the building cooling and heating systems is coming into wide spread due to assistance of domestic policies. However, there is a limitation that a design of ground heat exchanger taking 60% of construction cost is done by GLD and GLHEPRO programs without specific guidelines and consideration on Entering Water Temperature(EWT). For getting an optimal EWT, we analyzed the costs for construction of ground heat exchanger and cooling and heating for 15 years. In the results, reduction of construction costs as the length of ground heat exchanger shortens was much greater than increase of the electrical power consumption as COP gets low. EWT that COP of heat pump can be 3.76 or above was below $31^{\circ}C$ in cooling and was over $5^{\circ}C$ in heating.

Purpose - Korean traditional markets are falling behind the times, because they have not met the demands of social changes including: an overall improvement in standards of living, shift in purchasing form and propagation of cars. It is one of the most indigenous and conventional foods of Korea, taking a seat far in the corner of Korean traditional culture. Research design / data / methodology - Korean traditional rice cakes however have their limits. They are produced and sold by independent shop owners who cannot compete with the brand power of franchise organizations. The leadership of adminstration is needed for these shop owners particularly in visual merchandising related to interior design and display. Results - Additionally, the advent of major company-run rice cake cafe adds fresh fuel to the problem in addition to small but luxurious packaging. Small business owners need packaging technology for overall quality improvement of sales of rice cakes. Additional help is needed with the mode of packing to promote sales and win consumer confidence. Conclusions - Further assistance with marketing for seasonal displays is needed as well as teaching business owners how to read graphic data. Regular specialized education for visual merchandising of rice cakes could help independent market owners win the competition against franchise-based organizations.
