본 보고서에서는 중소기업자간 경쟁제품 지정제도는 특정 품목에 대해 중소기업자만 공공조달시장 진입을 허용하는 제도로 3년마다 품목을 지정한다. 2007년 공공조달시장 중소기업 지원제도가 단체수의계약제도에서 중소기업자간 경쟁제품 지정제도로 전환된 이후 9년간 시행중이다. 한경연은 “중소기업 보호의 긍정적 측면에도 불구하고 특정 품목을 지정해 대기업, 중견기업 진입을 차단함으로써 조달시장의 경쟁을 저해하는 문제를 안고 있다”고 지적했다. 공공조달의존도가 높을수록 중소기업 매출성장률이 감소하는 것으로 나타났다. 2011년부터 2013년까지 1,172개 표본기업의 매출액 대비 공공조달실적 비율을 분석한 결과, 공공조달의존도가 높을수록 중소기업 매출성장률이 감소하는 것으로 분석됐다. 이에 대해 연구를 수행한 김재현 중견기업연구원 연구위원은 “중소기업자간 경쟁제품 시장 내에서 조달의존도가 높은 중소기업들이 민간시장을 공공시장으로 대체하는 구축효과에 따른 현상”이라고 해석했다. 김 연구위원은 “독점 판로지원 방식이 오히려 중소기업의 성장을 둔화시키고 있다”며, “대기업?중견기업과의 경쟁을 허용해 이들의 성장을 견인해야 한다”고 주장했다. 해외 공공조달시장에서의 중소기업 지원제도의 경우, 미국은 일정 금액구간을 설정해 중소기업에 할당하고 있고, 일본은 국가에서 지정한 중소기업 적격조합에 수의계약 특혜를 부여하고 있으나 의무사항이 아닌 선택사항으로 우리에 비해 느슨한 지원체계를 갖추고 있다. 또 EU는 조달시장에서 중소기업에 특혜를 제공하는 별도 규정이 없으며, 사회적 기업이나 사회공헌 기업에 입찰참가 시 가점 부여 제도 등을 시행하고 있다. 이에 대해 한경연은 “중소기업자간 경쟁제품 지정제도 개선방안으로 조달시장의 경쟁확대를 위해 공급집중이 크게 나타나는 상위 금액구간 계약에 대기업과 중견기업의 참여를 허용해야 한다”고 주장했다. 이밖에도 미국제도와 같이 계약특성에 따라 중소-중견-대기업이 함께 참여하는 방안을 제안했다. 김 연구위원은 “중소기업자간 경쟁제품으로 지정된 품목이라 하더라도 조달계약의 특성에 따라 중견기업과 대기업의 참여를 허용할 필요가 있다”며, “이를 위해 조달물품 중 높은 품질등급이나 안전등급이 필요한 계약에 대해 중소기업과 중견 및 대기업의 공동참여를 위한 명확한 규정마련이 필요하다”고 주장했다. 2011년부터 2013년까지 조달청 중앙조달실적자료를 분석한 결과, 중소기업자 간 경쟁제품 계약에서 상위 기업의 집중도가 높은 것으로 나타났다. 특히 상위 10% 계약 금액 구간 내에서는, 전체 품목 중 상위 1위 기업의 공급 집중도가 50%가 넘는 품목이 절반에 달했다. 이는 금액이 높은 계약의 경우 상위 기업의 공급집중도가 심화되었다는 의미다. 대표적으로 콘크리트파일 품목의 경우, 2013년 1위 기업의 공급 집중도가 약 64.9%로 나타났다.

This paper tries to investigate the formation process and characteristics of modern philosophical system in Korea. For this, the author begins to explore’How we have to see the modernity in Korea’. Then he presents the Japanese adoption of western philosophy and Japanese colonial policy. On the one hand, the formation process and characteristics of modem philosophical system in Korea was determined partly by the japanese colonial policy, on the other hand it was determined partly by the philosophical contents in Japan. In this connection, this paper illuminates contents and characteristics of adoption of western philosophy. Korean philosophers such as Shin Nam-Chul, Pak Chong-Hong tried to make a modern korean philosophy, although they accepted western philosophy through Japan. Therefore we have to valuate their works positively. Finally, the author examines the importance of translation in the process of modernization in Japan and Korea. The characteristics of the translation were changed according to the historical stages, and changing characteristics mean shifts in political, cultural interaction and hegemony. Therefore Korean modernity can be defined as ’triple -translated modernity’ influenced by West, China and Japan.

사진이란 빛으로 그리는 그림이다. 카메라의 파인더로 보고 느낀 아름다움을 구도와 구성으로 담아서 적절한 빛을 이용하여 사진 안에 담는다. 풍경사진의 기본은 자연이 만들어낸 아름다움과 마주하게 되는 순간부터 시작이다. 아름답고 신비로운 곳으로 걸어 들어가면 카메라 렌즈 안으로 이미 풍경이 녹아든다.

The purpose of this study was to analyze the influence of hocky players' cohesion power and team satisfaction on recognized performance and to suggest basic data which may improve recognition performance ability. To attain such purpose, 247 hockey players were selected using cluster sampling and one-way ANOVA and canonical correlation analysis were conducted using SPSS 9.0. Through those methods and analysis, this study reached the following conclusion. 1) For subfactors of team satisfaction, female showed relatively higher satisfaction than male in leader, team member, and environment. For subfactors of cohesion power, male was stronger in 'individual task' and 'group society' and female in 'individual society'. 2) For subfactors of team satisfaction, there was significant difference statistically in team member and environment except leader according to hockey players' own team. Commercial team showed higher satisfaction in team member and college team and commercial team had higher satisfaction in environment. 3) For subfactors of team satisfaction, there was significant difference statistically in team member and environment except leader according to players' career. In comparison of subfactors of team's cohesion power, players with more than 10-year career showed the highest value in 'individual task' and 'group task'. 4) Team satisfaction had the highest correlation with team member, followed by leader and environment. 5) Of subfactors of team satisfaction, recognition performance ability of team had the highest correlation with team member. 6) Of subfactors of cohesion power, cohesion power of team had the highest correlation with 'group society'.

Background/Aims: Early diagnosis of peritoneal metastases in patients with colorectal cancer (CRC) can influence patient prognosis. The aim of this study was to identify the clinical significance of carcinoembryonic antigen (CEA) in peritoneal fluid detected during operation in stage I-III CRC patients. Methods: Between April 2009 and April 2015, we reviewed medical records from a total of 60 stage I-III CRC patients who had peritoneal fluid collected during operation. Patients who had positive cytology in the assessment of peritoneal fluid were excluded. We evaluated the values of CEA in peritoneal fluid (pCEA) to predict the long-term outcomes of these patients using Kaplan-Meier curves and Cox regression models. Results: The median follow-up duration was 37 months (interquartile range, 21–50 months). On receiver operating characteristic analysis, pCEA had the largest area under the curve (0.793; 95% confidence interval, 0.635–0.950; P=0.001) with an optimal cutoff value of 26.84 (sensitivity, 80.0%; specificity, 76.6%) for predicting recurrence. The recurrence rate was 8.1% in patients with low pCEA (<26.84 ng/mL, n=37), and 52.2% in patients with high pCEA (≥26.84 ng/mL, n=23). In multivariate Cox regression analysis, high pCEA (≥26.84 ng/mL) was a risk factor for poor cancer-free survival (CFS) in stage I-III patients. Conclusions: In this study, we determined that high pCEA (≥26.84 ng/mL) detected during operation was helpful for the prediction of poor CFS in patients with stage I-III CRC.

Background : Bioactive substances, viscumneoside III and homoflavoyadorinin B, were isolated from korean mistletoe. Before, the isolated compounds were performed to identify the effect on tyrosinase inhibition activity. It is generally known that the biological activity of aglycon is better than the glycone attached to sugars in natural products. Methods and Results : In this study, the glycone of mistletoe were converted into homoeriodictyol and velutin, which are aglycon, respectively, by microwave irradiation, and their tyrosinase inhibitory activity was investigated. Experimental results showed that microwave irradiation mistletoe extracts showed superior tyrosinase inhibitory activity than untreated extracts. Conclusion : These results revealed that the whitening acivity of microwave irradiation Korean mistletoe can be utilized for the skin cosmetics.

LAM (Laser Assisted Machining) has several advantages, such as high productivity, reduction of manufacturing cost, high quality, and a narrow HAZ (Heat Affected Zone). Studies on LAT (Laser Assisted Turning) have been largely conducted in recent years. However, there have been certain limitations in performing studies that focus only on the LAT of cylinder shapes throughout the world. Therefore, LATM (Laser Assisted Turn-Mill) is proposed in this study for machining complex geometries, such as square and spline members. In the case of LATM processes, it is more difficult to estimate the temperature after completing a preheating process because it represents an elliptical shape as a laser heat source is inclined. A new laser heat source projection method is proposed for the analysis of such square and spline members. The temperature distribution of the members based on their rotation is predicted. The results of the analysis are compared with that of LATM experiments. The results reveal that the cutting force in machining SM45C is reduced by about 8-14%, while the surface roughness is reduced by about 25-40% compared with that of conventional turn-mill processes.
