The purpose of this study is to review the research on Gangbang Palace and to presume the location of the palace through the study of feng shui. when the Mongols invaded, Ganghwado was the capital, moved from Gaegyeong and it was maintained for 39 years. At that time, the palace construction followed the palace of Gaegyeong, and the names such as Gujeong毬庭, Palace, and Sasa寺社 were the same as those of Gaegyeong. However, despite several archaeological excavations at Goryeo Palace Site, Historic Site No. 133, no actual remains of the Goryeo period were found. After the negative opinions on the current Goryeo Palace site became public, there have been several previous studies on the estimation of the location of the Goryeo Palace Site, and although there have been achievements, the location of the Goryeo Palace is still not confirmed. The key to presuming the location of the GangdoPalace江都宮闕 is first, whether the palace was located in the south of Songaksan, and second, at what point it was located in the south of Songaksan. As to whether the palace was located in the south of Songaksan, it was presumed that the Chiso治所 of Ganghwabu was located in Gukhwari, referring to the record in 『Shinjeungdongguknyeojiseungnam新增東國輿地勝覽』 that Goryeosan, a guardian mountain鎭山, was 'five ri west of Bu府西五里'. Accordingly, the location of the palace of 'Budongsimni 府東十里' in the old literature was estimated to be south of Songaksan Mountain. Also, the location of the palace on the south side of Songaksan was approached from a feng shui theory. Three places for the palace to be located are presumed to be 'Ganghwa Girls' High School', 'Seonggwang Church', or 'Above the Ganghwa-gun library', and the central axis of the palace is estimated to be 'Above the Ganghwa-gun library' where the corridor-type building relics were found among them, and the other two areas were presumed to be other buildings within the palace.

To achieve cost and size reductions, we developed a low cost manufacturing technology for RF substrates and a high performance passive process technology for RF integrated passive devices (IPDs). The fabricated substrate is a conventional 6" Si wafer with a 25${\mu}m$ thick $SiO_2$ surface. This substrate showed a very good insertion loss of 0.03 dB/mm at 4 GHz, including the conductive metal loss, with a 50 ${\Omega}$ coplanar transmission line (W=50${\mu}m$, G=20${\mu}m$). Using benzo cyclo butene (BCB) interlayers and a 10 ${\mu}m$ Cu plating process, we made high Q rectangular and circular spiral inductors on Si that had record maximum quality factors of more than 100. The fabricated inductor library showed a maximum quality factor range of 30-120, depending on geometrical parameters and inductance values of 0.35-35 nH. We also fabricated small RF IPDs on a thick oxide Si substrate for use in handheld phone applications, such as antenna switch modules or front end modules, and high-speed wireless LAN applications. The chip sizes of the wafer-level-packaged RF IPDs and wire-bondable RF IPDs were 1.0-1.5$mm^2$ and 0.8-1.0$mm^2$, respectively. They showed very good insertion loss and RF performances. These substrate and passive process technologies will be widely utilized in hand-held RF modules and systems requiring low cost solutions and strict volumetric efficiencies.

반응 진행 변수 보존 방정식 및 1단계 비가역 반응과 연계된 고해상도 전산유체 코드를 이용하여 관 내부를 전파하는 데토네이션 파의 삼차원 구조를 관찰하였다. 코드는 영역 분할에 기초하여 MPI 라이브러리를 이용하여 병렬화하였으며, AMD 프로세서로 구성된 Windows 클러스터를 이용하여 실행하였다. 삼차원 비정상 해석으로부터 데토네이션 파의 불안정성으로 유발된 그을음 막 기록(smoked-foil record)을 얻을 수 있었으며, 이로부터 초기 교란 조건에 따라 직사각 모드나 대각 모드의 셀 구조와 함께 작은 반응 상수 조건에서는 회전 데토네이션 파를 관찰할 수 있었다.

This paper addresses numerically the behavior of steel structures under Fire-after-Earthquake (FAE) loading. The study is focused on a four-storey library building and takes into account the damage that is induced in structural members due to earthquake. The basic objective is the assessment of both the fire-behavior and the fire-resistance of the structure in the case where the structure is damaged due to earthquake. The combined FAE scenarios involve two different stages: during the first stage, the structure is subjected to the ground motion record, while in the second stage the fire occurs. Different time-acceleration records are examined, each scaled to multiple levels of the Peak Ground Acceleration (PGA) in order to represent more severe earthquakes with lower probability of occurrence. In order to study in a systematic manner the behavior of the structure for the various FAE scenarios, a two-dimensional beam finite element model is developed, using the non-linear finite element analysis code MSC-MARC. The fire resistance of the structure is determined using rotational limits based on the ductility of structural members that are subjected to fire. These limits are temperature dependent and take into account the level of the structural damage at the end of the earthquake and the effect of geometric initial imperfections of structural members.

Rural development policy has changed from hardware based development to community revitalization. The purpose of this study is to analyze social network of collaborative activity among rural organizations as fundamental of community. The material used in this study is a record of collaborative activites in the community newsletter of Hong-Dong area. 161 of collaborative activities (links) and 75 of organizations (nodes) are investigated in network. 6 collaborative activity type ('Education', 'Socializing', 'Meeting', 'Culture', 'Event' and 'Labor') is classified. 'Socializing' is inclusive of approximately half of whole network (50.67%). Closeness centraization, degree centralization and betweenness centralization are measured on top in 'Education', 'Meeting' and 'Event' type. Scatter plot analysis using degree and betweenness centrality index, 'Maeul Revitalization Center', 'Balmak Library', 'Woori-Maeul Medical Co-op', 'Support Center for Female Farmers', 'Hongdong Middle School' and 'Mundang Sustainable Agriculture Education Center' are resulted as the core organization in network. Geographical distribution of collaborative activity is not only concentated in Hong-Dong Myeon but also networked with adjacent administrative district. This study finds its purpose in the detailed analysis of network characteristics of collaborative activity within Hong-Dong area which is representative developed rural community in Korea.

Despite recent clinical guidelines, the optimal therapeutic strategy for the management of refractory chronic cough is still a challenge. The present systematic review was designed to assess the evidence for efficacy and safety of gabapentin in the treatment of chronic cough. A systematic search of PubMed, Embase, Cochrane Library databases, and publications cited in bibliographies was performed. Articles were searched by two reviewers with a priori criteria for study selection. Seven relevant articles were identified, including two randomized controlled trials, one prospective case-series designed with consecutive patients, one retrospective case series of consecutive patients, one retrospective case series with unknown consecutive status, and two case reports comprising six and two patients, respectively. Improvements were detected in cough-specific quality of life (Leicester Cough Questionnaire score) and cough severity (visual analogue scale score) following gabapentin treatment in randomized controlled trials. The results of prospective case-series showed that the rate of overall improvement of cough and sensory neuropathy with gabapentin was 68%. Gabapentin treatment of patients with chronic cough showed superior efficacy and a good safety record compared with placebo or standard medications. Additional randomized and controlled trials are needed.
