본 연구는 제주특별자치도 내 실적공사비가 적용된 도로현장을 중심으로 물가변동에 따른 실적공사비 등락률 산정의 문제점을 분석하기 위하여 실시되었다. 본 연구를 위하여 제주특별자치도 내 9개 도로공사 현장을 중심으로 실적공사비방식, 표준품셈방식, 건설공사비지수방식에 따른 등락률을 비교 분석하였다. 분석결과 9개 현장 중 약 56%인 5개 현장에서 실적공사비의 지수조정률이 표준품셈과 건설공사비지수의 지수조정률에 비해 낮게 산정되었다. 이는 실적공사비가 적용됨에 따라 물가변동으로 인한 계약금액 조정 성립요건이 지연되고 있다는 것을 알 수 있으며, 이에 따라 공사 준공 전 물가변동으로 인한 계약금액 조정횟수의 감소와 함께 물가변동금액 역시 차이를 보일 수 있음을 의미한다. 또한, 건설공사비지수 사례분석 결과, 도로부문에 대한 지수를 적용하여 지수조정률을 산출하였으나 지수조정률이 2.0%~9.4%까지 산정되어 이는 공사금액 및 물가변동 적용시기에 따라 상당한 영향을 미치는 문제점이 나타났다. This study has conducted case studies in order to suggest alternatives to the historical data-based estimate system. Price fluctuation calculation methods based on historial cost indexes, standard estimate and construction cost indexes were applied to 9 road construction sites in Jeju for an analysis. As a result, in 5 construction sites (about 56% of 9 sites), the index control rate calculated based upon historical data-based estimate system was higher than that calculated based upon standard estimate and construction cost indexes. Thus the establishment of the requirements for the adjustment of contract price due to price fluctuation delays, which leads to a significant difference in price fluctuation amount. And, in an analysis of construction cost indexes, the indexes for road construction were used for calculating index control rate which ranges from 2.0 to 9.4 percent, indicating the time of construction amount and price fluctuation application has a significant influence on index control rate.

Traditionally, players in sports fields are selected through intuition by individual or groups such as coaches or selecting committees. The procedures of selecting has often occurred dispute in aspect of validity even though they have used objective data. The purpose of this study was to rank in relative importance on performance assessment based on handball players’ positions using Delphi and AHP method. Coaches, commentators, referees were selected for Delphi method as experts. After that, the same cluster of occupation were selected for AHP method. As a result of this study, First, positions of handball game are goal keeper, center back, pivot, both backs, and both wings. Second, significant positions for winning in handball game are in the order of goal keeper, center back, pivot, both backs, and both wings. Third, significant factors for evaluating athletic performance of goal keeper position are in the order of total saved efficiency, and assist. In case of center back position are in the order of assist, break through shoot score, total scored efficiency, 9M shoot score, 6M shoot score, and error. In case of pivot position, factors are in the order of 6M shoot score, total scored efficiency, break through shoot score, fast break score, and error. In case of both backs positions, factors are in the order of 9M shoot score, break through shoot score, total scored efficiency, assist, 6M shoot score, and error. In case of both wings positions, factors are in the order of wing shoot score, fast break score, 6M shoot score, total scored efficiency, break through shoot score, and error. Determinant factors and the importance through the study can be utilized as an objective indicator in handball field. In addition, this data will be used for systematically evaluating each player and team’s athletic performance and developing that.

본 연구는 이중물류구조, 물동량 불균형, 물류 인프라 구축 미비 등으로 타지역보다 물류비가 과다하게 소요되는 제주지역 물류비 절감 방안 마련이 요구되는 상황에서, 제주지역 반출 물동량 발생의 주요 화물인 농산물을 중심으로 물류비를 분석하고자 하였다. 이를 위해, 제주 농산물의 출하 현황 및 유통·물류 실태를 분석하고, 국토교통부의 ‘기업물류비 산정지침 기본해설서`에 의한 원가산정 조사에 의해, 산지에서 도매시장까지의 유통단계별 물류비를 산출하였다. 본 연구의 분석 결과 및 시사점은 다음과 같이 요약된다. 첫째, 제주 농산물의 산지에서 도매시장까지의 톤당 물류비는 서울지역으로 출하할 경우 258,493원으로 가장 높고, 다음으로 영남권(242,784원), 호남권(218,698원) 순으로 높게 나타났다. 둘째, 2014년 도외 반출되는 제주 농산물 총 물류비는 2,212억 7,328만원으로 분석되었다. 이중 도외 반출되는 제주 농산물(877,406 톤)의 해상물류비는 740억 4,867만 원(2014년 기준)으로 나타났다. 이와 같은 결과는 제주지역의 경우, 도서지역으로 국내 농산물 주요 생산지임을 고려할 때, 국내시장 수급 및 가격 안정을 위한 생산기반의 지속적 유지, 도서지역 시장경쟁력의 제고와 유통 체계 개선 유도, 새로운 물류단계 및 물류기술 개발, 물류체계 개선 및 물류 네트워크 구축, 항만·선박·물류시설 등의 물류 인프라 정비, 선진 물류 업체 유치 및 물류기업의 경영 합리화, 농산물 포장재 개발, 물류 해상운송비 지원 등의 물류비 절감 방안 정책이 필요함을 시사한다. The purpose of this study was to calculate logistics cost of Jeju agricultural products were flowed from Jeju to wholesale market in the process of distribution to find a method of reducing logistics costs of them excessively consuming than the other regions. For this purpose, we analyzed the status of distribution and logistics of Jeju agricultural products and the logistics costs of them were yielded by the ‘cost estimating method based on logistics company guidance manual`of Ministry of Land, Infrastructure and Transport according to processes of distribution were flowed from Jeju to the wholesale market of inland. Studies are showed that Jeju agricultural products shipped through maritime transport were 877,406 tons by 2014 and maritime logistics costs per ton was calculated at 84,395 won, as a result, the entire maritime logistics costs were accounted for 74 billion won. The total logistics costs of Jeju agricultural products were estimated over 221 billion won from production areas to the wholesale market yearly. These survey results are significant to be as data that can recognize the scale of total logistics costs required to ship of the Jeju agricultural products annually. Above all, these survey results about logistics costs of Jeju agricultural products can be utilized to reduce the heavy burden of distribution costs for Jeju farmers.

Morphea is an autoimmune condition characterized by excessive accumulation of collagen in the skin and underlying tissues. Lichen sclerosus (LS) is another connective tissue disease for which an autoimmune cause has been proposed, given the high association with other autoimmune diseases. The coexistence of morphea and lichen sclerosus has been sometimes reported in the literature, and is suggestive of a common pathogenic background between the two diseases. Among various types of morphea, generalized morphea has been associated with an increased rate of autoimmune disease, including LS. We report a case of extragenital LS during the progression of linear morphea into generalized morphea. (Korean J Dermatol 2015;53(9):713∼716)

Sarcoidosis is a systemic granulomatous disease of unknown origin that may affect multiple organs including the lung, mediastinal and peripheral lymph nodes, eyes, and skin. Although cutaneous manifestations occur in around 25% cases, to our knowledge, oral mucosal involvement is very rare as a leading symptom of sarcoidosis. A 28- year-old female presented with localized skin-colored to yellowish indurated papules and plaques on the lower lip mucosa. The lesions were presented for the past month and it progressively enlarged. Histopathologic examination revealed multiple, variable sized, well circumscribed, non-caseating granulomas in the dermis. Serum level of angiotensin converting enzyme was slightly elevated (63.0 U/L) and chest CT revealed bilateral hilar lymphadenopathies. Herein, we report an oral mucosal sarcoidosis, as an initial presentation of the systemic sarcoidosis. (Korean J Dermatol 2012;50(2):186~189)

The purpose of this study is to examine the propriety of foreign design specification of screw connections in the specification for the design of cold-formed steel structural members and to offer the pertinent data of screw connections for the design of cold-formed steel structural members. We carried out the tensile testing of screw connections. The test parameter were the end distance, the diameter of screw, the sheet thickness or ratio of sheet thickness, and the shape of section. The test results showed that failures generally went from (a) tilting and Pull-out failure, to (b) bearing failure, to (c) screw shear failure. The strength of screw connection is increased according to increment of the diameter of screw, the sheet thickness or ratio of sheet thickness.

The purpose of this paper is to suggest pertinent data requiring the design of a bolt connection in cold-formed steel structure. We carried out many experiments which are varied, for example, various bolt sizes and bolt hole sizes. We compared experimental results with AISI(1996) conditions and tried to verify the validity of current design criteria on Inside sheet of double shea connection of cold-formed steel. It is thought that it is safe to design bolted inside sheet of double shear connections in cold-formed steel to be bearing failure because the behavior of bearing failed specimens is more ductile than longitudinal shear failed specimens. Therefore, It demands considerations for the size of bolt holea, condition of using washers, the a/d, the torque, the shape of longitudinal shear failure in the specification for the design of cold-formed steel structural members.
