  • Background: Associations between Arg399Gln, Arg194Trp and Arg280His polymorphisms of the XRCC1 gene and risk of differentiated thyroid carcinoma (DTC) have been widely studied but the findings are contradictory. Methods: We performed a meta-analysis in the present study using STATA 11.0 software to clarify any associations. Electronic literature databases and reference lists of relevant articles revealed a total of 10, 6 and 6 published studies for the Arg399Gln, Arg194Trp and Arg280His polymorphisms, respectively. Results: No significant associations were observed between Arg399Gln and DTC risk in all genetic models within the overall and subgroup meta-analyses, while the Trp/Trp vs Arg/Arg and recessive model of the Arg194Trp polymorphism was associated with DTC susceptibility, and the dominant model of Arg280His polymorphism contributed to DTC susceptibility in Caucasians. Conclusions: Our meta-analysis suggests that XRCC1 Arg194Trp may be a risk factor for DTC development.

  • Three fungal isolates, NNIBRFG108, 1139, and 1480, were isolated from freshwater environments; NNIBRFG108 from plant litter in Samcheok, Gangwon and NNIBRFG1139 and 1480 from the soil in Jeju & Gimcheon, Gyeongbuk, Korea. Based on the morphological characteristics and phylogenetic analysis of internal tanscribed spacer (ITS), 28S rDNA region, and ${\beta}$-tubulin gene, NNIBRFG108, NNIBRFG1139, and NNIBRFG1480 isolates were confirmed as Didymella segeticola, D. ellipsoidea, and D. aeria, respectively. Neither species has previously been described in Korea.

  • In this paper, changes of railway-related organization during the Japanese colonial period were studied indepth. The railway-related organizations were expanded from the Railway Management Bureau in 1906 (Residency-General). In 1910, this bureau changed to the General of Chosun Railway Bureau (Government-General) and the Chosun Railway Bureau (Government-General). In the 1940's, it developed into an organization called the Transport Bureau, dealing with the whole transport service. The number of employees in the railway sector increased along with the expansion of the organization and the establishment of a training institution for better recruitment. After examining the period of the construction of railway and connection system, which is deeply related to the railway organizations of the Japanese colonial period, this paper analyzes the transformation process of railway-related laws and organizations. Furthermore, this paper finds common characteristics and differences between railways in a comparison of three countries: Chosun, Japan and Taiwan.

  • In the product development stage, it is very important to ensure demanded quality level before moving to the full-scale manufacturing. For example, in developing guided weapons, live-fire tests are required to verify the final performance of the weapons which are very expensive. The quality evaluation of the guided weapons needs destructive testing, which makes it necessary to test as small number of samples as possible. This paper presents sampling inspection plans and calculating system for finite population guided weapons, which can meet the demanded quality level and confidence level with the minimum number of performance tests. The result of this paper can be useful for any kind of costly destructive testing.

  • The historical consciousness of furniture is one of the crucial elements that become the medium for initiating design. Also, it is an important task of the science to figure out the headstream of furniture being used these days. From this purpose, this study intends to understand the bureau that has not been studied much in terms of the headstream and changes based on historical facts centering around England, France, or America regarding the forms or terms. These points are expected to be used as the foundational research data to develop the science and products.

  • 최근 각광받고 있는 RFID(Radio Frequency Identification) 기술은 물류, 유통 및 자산관리 분야를 중심으로 그 적용 사례들이 늘고 있다. 본 사례는 정보통신부의 IT839정책의 일환으로 RFID분야의 기술 및 산업 확산을 위해 한국전산원이 주관하여 추진한 2005년도 선도사업 중 하나인 공군 신무기(F-15K) 자산관리시스템 구축사업에 대한 것이다. 이 시스템의 구축을 통해 공군은 군수물자의 정확한 도입현황 파악이 가능하게 되었고, 보유 자산의 현황 및 저장위치 파악이 실시간 가능해졌으며, 수령, 저장, 발송, 재고관리 등 기존의 업무 처리 방식을 간소화하여 업무 소요시간 및 인력을 절감할 수 있었다.
