The wooden stupa of Nungsa was reconstructed with special references to construction resources of Baekje and adjacent countries of the period. In this study, the construction of underpinning of the stupa was analyzed in comparison with 5-story stupa of Buepryungsa temple in Japan and other domestic relics. Regarding the elevation scheme of the structure, it was compared with the elevation proportion of stupa in the Baekje period. And the analysis brought out the following results. The construction method of Nungsa 5-story and elevation form technique applied in wooden stupa shall be used as a basic indirect resource to prepare restoration plans for Baekje wooden stupa.

The architectures of DaPo type had developed being used for the main buildings of palaces and temples, the development has been more specially on the design than the construction. The existing buildings like the Kunjongjon in GyeongBok-gung, the Injungjun in the Changduk-gung and the Junghwajeon, in the Deoksu Gung are Royal Palaces including the technical and the idea from the epoch when Salmi(an elaborate curlicue ornamentation at the top of a pillar) had spent years perfecting its design. The Korean traditional wooden architectures have developed and been more important on an overall harmony than in part. SalMi is really necessary for the formation of GongPo(bracket) and in suit with the architectures, being changed from the length to diagonal lines angle to diagonal cuttings angle to curvature on the DanBu(end of zones) The efforts for the design had sublimated the balance and harmony, it was enough to appear the great glory and magnificence on the architectures of Dapo type of the 19th royal palaces with Chogak style and Wungong style. The aim of study is to understand the feature of SalMi considering the length, the diagonal lines angle, the diagonal cuttings angle and curvature on the DanBu on the architectures of Dapo type of the 19th royal palaces.

In Korea, only a few wooden pagodas are extant because some wooden pagodas were lost due to artificial environment like war. Fortunately, only Eight Depictions Hall(Palsangjeon) in Beobjusa temple and main hall of Ssang-Bong Sa the main temple are extant. Though main hall of Ssang-Bong Sa the main temple shows old style in construction and outstanding creativity, survey and investigation for the hall have been poor. Accordingly, this study investigated pillar part, bracket structure part, and roof part composing pagoda body section which actively reflects structure and design skill compared to floor or upper part. And for better understanding, in the part that is similar to pagoda body section of main hall or needs examples, wooden pagoda in China or Japan was referred. Through this investigation, it was known that unique skill applied to main hall of Ssang-Bong Sa the main temple is based on plane in one room ${\times}$ one room - Ssang-Bong Sa the main temple has common form of wooden pagoda in appearance.

본 연구는 연안화물선사의 동태적 효율성과 운영방안을 제시하기 위하여 DEA분석을 수행하였다. 분석대상 업체(DMU)는 연안화물만을 수송하는 업체 중 2018년 매출액 기준 연안화물선사 상위 12개 업체를 선정하였다. 동태적 효율성 변화를 살펴보기 위하여 2008년부터 2017년까지 10개년 자료를 수집하여 DEA-Window 분석을 수행하였다. 분석결과 주로 남해권역에 있는 업체들의 효율성이 높았으며, 시기별로 효율성이 급격히 변화하는 선사의 경우 내항화물운송수입의 감소 혹은 다른 선사들의 효율성 감소로 인한 상대적 효율성 증가로 이어졌음을 알 수 있었다. 분석결과를 통해 연안화물선사의 운영효율성을 강화하기 위해서는 적정선복량 관리 방안, 생산성 향상을 위한 기술변화 요구, 연안해운 인프라 개선, 노후선박에 대한 지원정책이 필요한 것으로 나타났다. 본 연구는 기존에 확보하기 어려웠던 연안화물선사들의 데이터를 수집하고, 연안화물선사의 매출원가에 해당하는 선비, 선원비, 유류비, 운항비를 모두 변수로 사용함으로써 기존 연구에 비해 실증적인 연구를 수행하였다는 점에서 연구의 차별성이 있다. The aim of this research is to obtain the operational efficiency of coastal cargo shipping companies using DEA-Window and Malmquist analysis. The analysis targets (DMU) selected the top 12 coastal cargo carriers based on sales in 2018. The DEA-Window analysis was performed by collecting 10-year data from 2008 to 2017 to examine dynamic efficiency changes. According to the analysis, the efficiency of the companies in the South Sea area was high, and the efficiency of the shipping companies, which changed rapidly over time, led to a decrease in the internal cargo transportation revenue or a decrease in the efficiency of other shipping companies. According to the analysis results, in order to strengthen the operational efficiency of coastal cargo carriers, proper ship volume management measures, demands for technological changes to improve productivity, improvement of coastal shipping infrastructure and support policies for old ships are needed. This study has implication in that it has conducted empirical research compared to previous studies by collecting data from coastal cargo carriers that were previously difficult to secure and using all of the shipping, crew, oil, and operating expenses that correspond to the cost of sales of coastal cargo carriers as variables.

As the corner of wooden pagoda forms the roof by closely bordering left and right eaves on the various purlins and angle rafters, it is designed for every face to be recognized as front whose structure system increases load to bear proportionally. The corner of wooden pagoda is inseparable with the corner bracket set as it becomes stable thanks to the corner bracket set structurally and load burden under restrained structure makes the corner bracket set really important. Accordingly, this study could figure out some facts by analyzing corner bracket sets of Palsangjeon of Beobjusa Temple in Korea, Seokgatap of Bulgungsa Temple in China and Ojungtap of Beobryungsa Temple in Japan which were constructed with pure wooden structure. This study demonstrated that corner bracket set played a pivotal role in keeping balance of concentrated load of corner (corner of opening) in each floor that contributed to the stability of wooden pagoda structurally despite multiple duplications of floors and also figured out the outfit of corner bracket set was subject to the floor type and the cross section of Gongpo installed on top of Pyeongju. Wooden pagodas in 3 countries were two floor types of octagon and square, and employed different connection method between upper and lower floors. The difference between floor and duplication method determines the method of corner, but even different methods were sufficient to have entirety in every side by completing dynamic principle of corner bracket set even though old method had to solve the problem of concentrated load and it also confirms that it was essential Gongpo to prevent any deformation of corner.

냉동 냉장창고의 집적단지인 '콜드체인 클러스터' 구축이 물류업계의 현안으로 급부상하고 있다. 인천항만공사는 한국가스공사와 협력하여 송도 LNG 인수기지에서 발생하는 냉열 에너지를 이용한 냉동 냉장 클러스터를 구축하기 위한 사업을 진행 중에 있다. 본 연구에서는 CFPR 방법론을 활용하여 냉동 냉장 클러스터 활성화 방안을 제시하는 것을 연구의 목적으로 한다. 분석결과, 상위요인에서는 안정성과 수익성 요인이 0.281로 가장 중요시 되는 요인으로 파악되었다. 세부요인으로는 지속가능한 물동량 확보가 가장 높게 나타났고, 임대료 수준, LNG 냉열 활용기술의 지속 가능성과 일반 냉동 냉장창고와의 경쟁, 시설 중복투자 배제 등의 순으로 중요도가 평가 되었다. 향후 연구에서는 활성화 요인을 활용하여 국내 지역별 냉동냉장클러스터를 평가할 필요가 있다. The construction of a "cold-chain cluster," which is a complex of cold-storage warehouses is emerging as an issue in the logistics industry. The Incheon Port Authority, in partnership with Korea Gas Corporation, is carrying out a project to build a cold-storage cluster using cold energy generated in the Songdo LNG receiving terminal. This study proposes a method of activating the cold-storage cluster using the CFPR methodology. An analysis of major factors showed that the most important factor was stability and profitability, which scored 0.281. For sub-factors, sustainable trade volume was the highest in importance, followed by rent level, the sustainability of LNG cold energy utilization technology, competition with general cold-storage warehouses, and exclusion of duplicate investments in facilities. For the future study, the evaluation of complex of cold-storage warehouses using major factors drawn out from this study is needed.
