Many studies have suggested that the XRCC1 Arg280His gene polymorphism might be involved in the development of hepatocellular carcinoma (HCC). However, the results have been inconsistent. In this study, the authors performed a meta-analysis to assess the association between XRCC1 Arg280His and HCC susceptibility. Published literature from PubMed, EMBASE and CNKI Data was searched. Pooled odds ratios (ORs) and 95% confidence intervals (CIs) were calculated using fixed- or random-effects models when appropriate. Begg's test was used to measure publication bias. A total of 7 case-control studies covering 1,448 HCC cases and 1,544 controls were included. No significant variation in HCC risk was detected in any of the genetic models overall. In the stratified analysis, four studies with sample sizes over 300 produced similar results. The corresponding pooled ORs were not substantially altered after the exclusion of three studies deviating from Hardy-Weinberg equilibrium in the control group, which indicated reliability for our meta-analysis results.

This paper presents the theoretical development and qualitative evaluation of a new concept in the mathematical modeling of dynamic structures. We use both test data and analytical approximations to identify the parameters of an incomplete model. The model has the capability of predicting the response of the points of interest on the structure over the frequency range of interest and can be used to predict the changes in natural frequencies and normal modes due to structural changes. The theory was tested by running simulated tests on a relatively simple structure, identifying the parameters of the incomplete model, and using this model to predict the effects on frequency and mode shapes of several mass and stiffness changes. The conditions of the tests were varied by selecting different numbers of points of measurement, varying the frequency range, and by including assumed measurement error. It is recommended that the theoretical development be continued and that applications to more complex structures be carried out in order to develop a better understanding of the limitations and capabilities of the method. A successful, more definitive sevaluation could lead to immediate practical applications.

A reaction mixture was developed for formation of soft organic monolith that was easily smashed, rinsed, refluxed, filtered, and dried to give monolith particles having high pore volume of macropores. This phase was almost without mesopores. The reaction mixture was composed of methacrylic acid, ethylene glycol dimethacrylate, polyethylene glycol (porogen), and an initiator in a mixed solvent of toluene and isooctane. The selection of porogen and its amount was carefully carried out to obtain the optimized separation efficiency of the resultant phase. The median macropore size was 1.6 ${\mu}m$, and the total pore volume was 3.0-3.4 mL/g. The median particle size (volume based) was 15 ${\mu}m$, and the range of particle size distribution was very broad. Nevertheless the column (1 ${\times}$ 300 mm) packed with this phase showed good separation efficiency (N~10,000-16,000) comparable to that of a commercial column packed with 5 ${\mu}m$ C18 silica particles.

In this paper, electromagnetic wave environment generated from electronic equipments was investigated. Since the main source of electromagnetic waves are electronic equipments, the field intensity of a harmful electromagnetic wave was measured and its harmful level was analyzed. It was also found that the result was 23%${\sim}$38% in case of TV set and microwave oven. Based on this analysis, this study proposed efficient shielding method to suppress unwanted electromagnetic wave.

여러 가지 압축알고리즘 중에서 허프만 부호화는 데이터의 통계적인 중복성을 제거하기 위한 방법으로 많이 사용되어 왔다. 이제까지 허프만 테이블의 특성과 코드워드의 패턴에 따라 효율적으로 복호화할 수 있는 알고리즘이 많이 제안되었다. 본 논문에서는 8진 트리 검색 방법을 이용한 허프만 복호화 알고리즘을 제안하고 효율적인 하드웨어 구현 방법을 제안한다. 하드웨어의 메모리와 게이트 면적을 소형화하였고 빠른 검색을 위하여 알고리즘을 최적화하여 MPEG 오디오 복호화기 시스템에 적용할 수 있게 하였다.

There have been noticeable developments for the optimization of the highway and railroad alignments with the IT and computerized tools. The designers expect that all of the quantitative design elements should be considered. This study developed a methodology which can be useful for the vertical alignment design. It provides a accurate "vertical control point" searching method, and makes the vertical alignment optimization more efficiently. The vector method makes the searching faster and calculates more accurate application sections. The results from this method generate more reliable vertical alignments than the conventional raster method for less computation time.

The purpose of this research is to study a case of the minimalism on Game Graphic User Interface design in Computer game. It is to analyse the minimal tendency on Game Graphic User Interface design in several Computer games such as Prince of Persia, Mirror's Edge, Splinter Cell, Gears of War, Call of Duty4, Metro 2033, Crysis2. These games expanded the field of Game Graphic User Interface design with the unique form of minimalism. Minimalism came from the formative arts in the 1960s and influenced to other fields of art. It seems to be an expression of various styles that promptly meet the needs of the times. Therefore, in this research, I would highlight the phenomenon of minimalisation in Game Graphic User Interface design and research the influence of Minimalism that appears in modern design focused on "simplicity" and "minimum" which are representative trend of Minimalism.

Big data analysis, in the large amount of data stored as the data warehouse which it refers the process of discovering meaningful new correlations, patterns, trends and creating new values. The important issue of a meta-analysis is not the significance test, the effect size of the predictor variable on the criterion variable. We reviewed a total of 236 samples among 6 studies published on the topic related Collagen intake on skin between 2000 and 2016 in Korea. The results of the study are summarized as follows. First, we concluded that the path between before and after of Sebum (SB) had the largest effect size of (r = .416) Therefore, the effect of the Collagen intake intervention showed an explanatory power of 17 (%) about. Next, the path between before and after of Moisture (MS) had the higher the effect size of (r = .318). Thus, we present the theoretical and practical implications of these results.
