The purpose of the study is to establish priorities in integrated medicine policy. Delphi method was used in conducting a survey on integrated medicine specialists regarding the policies of integrated medicine and actions. For specialists in integrated medicine, total 17 persons selected included scholars who performed minimum one study on integrated medicine, medical staff who performing integrated medical service at institutions that implemented integrated medical care or those who were involved in creating or implementing policies on integrated medicine. The first Delphi-method survey conducted from Apr. 14 through 18, while the second survey was carried out from Apr. 21 through 25. To prioritize the policies based on the results of the mini Delphi-method survey, Analytic Hierarchy Process(AHP) was performed for 15 persons answered to mini Delphi-method from May 2 through 16, 2014. From the Delphi-method survey, four policies and 16 actions were obtained. AHP showed the first priority placed on 'Building the Infrastructure of Industrialization in the Integrative medicine' of the 4 policies and 'Developing new diagnostic and treatment instruments' was given the highest priority of the 16 actions. For implementation of integrated medicine policy, the 4 policies and the 16 actions found in this research require government support and should be urgently implemented according to its priority.

As we learn more about parasites in ancient civilizations, data becomes available that can be used to see how infection may change over time. The aim of this study is to assess how common certain intestinal parasites were in China and Korea in the past 2000 years, and make comparisons with prevalence data from the 20th century. This allows us to go on to investigate how and why changes in parasite prevalence may have occurred at different times. Here we show that Chinese liver fluke (Clonorchis sinensis) dropped markedly in prevalence in both Korea and China earlier than did roundworm (Ascaris lumbricoides) and whipworm (Trichuris trichiura). We use historical evidence to determine why this was the case, exploring the role of developing sanitation infrastructure, changing use of human feces as crop fertilizer, development of chemical fertilizers, snail control programs, changing dietary preferences, and governmental public health campaigns during the 20th century.

In this study, numerical analyses were conducted to investigate the load transfer mechanisms and dynamic responses between the vertical shaft and the surrounding soil using a dynamic analysis method and a pseudo-static method (called response displacement method, RDM). Numerical solutions were verified against data from the literature. A series of parametric studies was performed with three different transient motions and various surrounding soils. The results showed that the soil stratigraphy and excitation motions significantly influenced the dynamic behavior of the vertical shaft. Maximum values of the shear force and bending moment occurred near an interface between the soil layers. In addition, deformations and load distributions of the vertical shaft were highly influenced by the amplified seismic waves on the vertical shaft constructed in multi-layered soils. Throughout the comparison results between the dynamic analysis method and the RDM, the results from the dynamic analyses showed good agreement with those from the RDM calculated by a double-cosine method.

With the ready access to the high resolution satellite image data, users of and areas covered by satellite image data are constantly on the rise world-widely. Korea will also be able to take full advantage of the satellite data once the Korea Multi-Purpose Satellite 1 (KOMPSAT-l) is successfully launched. Harmonizing satellite data production and application technology and users' needs, along with the guiding policy is essential for promoting satellite data use. Up to now, the Korean government has mainly concentrated on developing production technology for the satellite instruments. However, the imminent task of independent satellite data production demands a promotion policy for satellite data use. In this context, the policy is defined as an important medium for identifying the role and status of satellite image information at the national level and also preparing the legal as well as systematic foundation for producing, building, distributing, and packaging satellite data. The present paper aims to examine the role and status of the satellite data as well as their current status and problems in Korea in reference to the National Spatial Data Infrastructure, and finally to provide the policy directions to promote the satellite data use in public sector on the basis of the preceding analyses.

구내통신은 건물내에 교환기 등의 전기통신설비를 구축하여 전화서비스는 물론 통신 운영 및 관리업무를 담당하는 설비로서 주택법 등에서 대규모 건물에 대해서는 구내통신설비를 구축하도록 규정하고 있다. 과거 전화서비스만 제공하던 시기에는 간단한 구조로 되어 있어 사용되는 전기의 사용량 이 많지 않았으나 아파트와 같은 공동주택의 건설이 많아지고 제공되는 통신서비스 역시 초고속인터넷을 비롯하여 각종 홈오토메이션 등 구내통신이 담당하는 서비스가 복잡 다양해 지면서 설비의 전기요금에 대한 이슈가 제기되고 있다. 현재 한국전력공사의 요금약관을 살펴보면 아파트와 같은 대규모 건물일 경우, 1전기사용장소 전체를 1전기사용계약단위로 하기 때문에 구내용 전기통신설비의 경우 가장 높은 요금인 주거용 전력요금을 적용받고 있다. 하지만 '사회기잔시설에 대한 민간투자법'에 따르면 전기통신설비는 항만, 수도, 집단에너지 시설 등과 함게 가회기반시설로 지정되어 있으며 다른 기간시설의 경우 산업용 전력요금을 적용받고 있어 형평성의 문제가발생하고 있다. 이에 본 연구는 현행 구내통신관련 법제를 살펴보고 구내통신요금의 합리적인 개선방안을 제시하고 한다.

Large-scale earthquakes pose serious threats to infrastructure causing substantial damage and large residual deformations. Superelastic (SE) Shape-Memory-Alloys (SMAs) are unique alloys with the ability to undergo large deformations, but can recover its original shape upon stress removal. The purpose of this research is to exploit this characteristic of SMAs such that concrete Beam-Column Joints (BCJs) reinforced with SMA bars at the plastic hinge region experience reduced residual deformation at the end of earthquakes. Another objective is to evaluate the seismic performance of SMA Reinforced Concrete BCJs repaired with flowable Structural-Repair-Concrete (SRC). A $\frac{3}{4}$-scale BCJ reinforced with SMA rebars in the plastic-hinge zone was tested under reversed cyclic loading, and subsequently repaired and retested. The joint was selected from an RC building located in the seismic region of western Canada. It was designed and detailed according to the NBCC 2005 and CSA A23.3-04 recommendations. The behaviour under reversed cyclic loading of the original and repaired joints, their load-storey drift, and energy dissipation ability were compared. The results demonstrate that SMA-RC BCJs are able to recover nearly all of their post-yield deformation, requiring a minimum amount of repair, even after a large earthquake, proving to be smart structural elements. It was also shown that the use of SRC to repair damaged BCJs can restore its full capacity.

When a fire occurs in a large-scale or complicated facility there is a possibility of large-scale loss of life if there is no information on the location of fire and the location of emergency exits for people to take shelter. Consequently, the fire or disaster prevention system and the shelter course guidance system that optimally guides the shelter course are necessary to reduce the loss of life. This paper proposes a shelter course guidance system using a sensor network to reduce the loss of life in a building where a fire occurs. The experimental result of this research shows that the shelter course guidance system provides the optimum shelter course to people in infrastructure when a fire occurs.

In the transition to a multipolar international system, the literature has focused on great power competition while little attention has been given to the strategic possibilities of smaller states. However, as a result of globalization, states are so closely interconnected that the primary strategies of even major powers are not to achieve zero-sum solutions but to create asymmetric dependency through which they can influence the behavior of other states and non-state actors. States are assisted in this effort by a variety of tools, including setting up institutions, direct economic influence and through building different forms of infrastructure connectivity networks. By discussing asymmetric dependency situations from the perspective of the great powers, the literature presents smaller states primarily as passive actors, paralyzed by their dependence on great powers. Our paper argues that interdependence allows smaller states to effectively influence larger actors and examines strategies from which smaller states can choose in order to influence the behavior of larger states. Despite an extremely asymmetric relationship between Myanmar and China, actors in Myanmar have sought to influence China's Myanmar policy. We examine a case study of the Myitsone Dam, including Myanmar's strategic aims, chosen strategy and limitations in maneuvering space. Semi-structured interviews with local decision-makers and stakeholders are conducted in order to portray the full picture. Our study concludes that further research on the influencing strategies of small states in response to asymmetric dependence can contribute to a better understanding of the interdependence of states.

Researches utilizing the fourth industrial revolution technology are being conducted as a breakthrough for improving the earthworker productivity. In order to make the earthwork site smarter, it is necessary to digitize the construction site topography at first. For this purpose, photogrammetry using drones and LiDAR on MMS have been recently used. The purpose of this study is to analyze the accuracy of LiDAR by installation angles for verifying the application of MMS in the construction site. As a result of comparing the coordinates measured by the total station and the LiDAR, a small error of about 1-2 centimeters was shown. It is confirmed that MMS could be well applied to the earthwork site. In addition, there was no significant difference in the accuracy of the acquired coordinates according to the installation angle of the LiDAR, but the shape of the point clouds was different. The larger the installation angle, the better the shape of the site terrain is measured.
