The purpose of this study is to research the reality criticism and its recovery sense which are materialized in the postwar novels that hold the big part in Korean literature. In order to do execute the research in this study, as the representative writer and novel, Chang Yong-hak was selected after observing the content of the meaning of the postwar novels which are pulled by the various ways to express. The reason why he was selected is that he opened a new literature world which is<br/> distinel from the previous writers, and he is still being widely acknowledged in the contemporary time and also in these days.

최용석,이재강,최용현,김영환,강천식,신말식,Choi, Yong-Seok,Lee, Jae-Kang,Choi, Yong-Hyun,Kim, Young-Hwan,Kang, Chon-Sik,Shin, Malsik 한국식품조리과학회 2015 한국식품조리과학회지 Vol.31 No.5

Iksan370 is a long-spike wheat developed by the Rural Development Administration yielding excellent features components such as cold resistance, disease resistance, and viviparous germination. The physicochemical and material properties of the raw wheat and milled flour of Iksan370 were analyzed to derive its appropriate uses. The raw wheat of Iksan370 showed high contents of ash and proteins at 1.71% and 13.7%, respectively. Its test weight of 763.0 g/L was similar to those of other varieties and its 1,000 kernel weight was high at 45.38 g. The milled flour of Iksan370 had an ash content of 0.45%, which corresponds with a class 1 flour, and its protein content is 12.18%, corresponding with strong flour. The damaged starch was 5.41%, which was lower than that of other varieties. The average grain size was $70.67{\mu}m$ and the grain distribution was at the level of a typical hard wheat. In the farinogram, the water absorption was 58.63%, which corresponded to the level of medium flour. The development time was 7.00 minutes, which was significantly lower than those of Jokyung and Keumkang. The degree of softening was 67.00 BU, similar to those of Yunbaek and Baekjoong. Among the physico-chemical characteristics, the high protein content and typical hard wheat grain distribution of Iksan370 were similar to those of strong wheat, usually used for bread making. However, in the farinogram, the dough development time was short and the degree of softening was high. As a result, Iksan370 was expected to have poor breadmaking properties and a small volume of the final bread product due to insufficient dough durability. On the other hand, Iksan370 showed the highest maximum gelatinization viscosity at 864.00 BU. Therefore, Iksan370 is expected to show glutinous texture when used for noodles and its flour appears to be appropriate for frying powders as well.

戰後小說에 구현된 현실비판과 극복의식

최용석(Choi Yong-seok) 중앙어문학회 2002 語文論集 Vol.30 No.-

The purpose of this study is to research the reality criticism and its recovery sense which are materialized in the postwar novels that hold the big part in Korean literature. Korean War was ironically functioned as the abundant material source of the postwar literature by showing the ever most tragic phases than any other disaster of one-race country. In order to do execute the research in this study, as the representative writer, Kim Sung-han and Chang Yong-hak were selected after observing the content of the meaning of the postwar novels which are pulled by the various ways to express. The reason why they were selected is that they opened a new literature world which is distinct from the previous writers, and they are still being widely acknowledged in the contemporary time and also in these days. We can acknowledge that these two writers developed the new literal field by endeavoring continuously for themselves through the postwar novels.

戰後小說에 具現된 현실인식-張龍鶴의 『非人誕生』과 『易姓序說』을 中心으로-

최용석 ( Choi Yong-seok ) 한국어문교육연구회 2003 어문연구(語文硏究) Vol.31 No.1

본고는 한국 현대소설에서 새로운 轉換의 契機를 마련한 戰後小說에 具現된 現實認識을 밝히기 위해 쓰여진 것이다. 그 대상 작가로 선정된 張龍鶴은 觀念的 글쓰기를 통해 인간 救援의 문제에 초점을 맞춘 창작 태도를 보여준다. 그리고 敍事的 戰略으로서의 張龍鶴의 현실인식은 동시대의 다른 작가들에 비해 보다 知的인 立場과 銳利한 觀察力으로 전쟁의 後遺症인 戰後의 不條理를 인간 조건의 본질에 비추어 探索함으로써 확보된 것이다. 더욱이 문학을 통한 사회 참여와 역사적 사명감을 강조한 그의 작가적 태도를 고려할 때, 문학을 사회 현상과의 유기적 관계 속에서 살피는 文學社會學的 접근이 이 글의 목적을 遂行하기에 보다 有效한 것으로 판단된다. 본 연구 대상인 非人誕生과 易姓序說에서 張龍鶴은 현대 문명과 그 이념이 본질적으로 虛構라는 사실을 고발하며, 그 극복 방안으로 인간 존재의 本來性이 回復된 자연 상태로 回歸할 것을 주장하고 있다.

정준상관 행렬도와 군집분석을 응용한 KLPGA 선수의 기술과 경기성적요인에 대한 연관성 분석

최태훈,최용석,Choi, Tae-Hoon,Choi, Yong-Seok 한국통계학회 2008 응용통계연구 Vol.21 No.3

정준상관 행렬도(canonical correlation biplot)는 정준상관분석에서 두 변수 집단에 의해서 측정된 다변량 자료에서 변수 집단 간의 관계와 개체들의 관계를 탐색하기 위한 2차원 그림이다. 이는 일반적으로 최용석 (2006, 1장)의 한 변수 집단에 의한 행렬자료에 대한 일반적인 행렬도를 두 변수 집단에 의한 행렬자료로 확장한 것으로 볼 수 있다. 최근에 Choi와 Kim (2008)은 개체들이 많은 대용량 자료에서 행렬도의 해석상 힘든 문제점을 지적하고 이를 극복하는 데 군집분석을 활용하는 방법을 제시하고 있다. 일반적인 행렬도에서 발생하는 대용량 자료에 대한문제는 정준상관 행렬도에서도 동일하게 발생하곤 한다. 본 연구에서는 2006년도 KLPGA 선수 중 상금 순위 상위 50명을 대상으로 정준상관 행렬도를 통해 기술요인변수군(평균 퍼팅수. 그린 적중율, 파 세이브율, 파 브레이크율)과 경기성적요인변수군(상금, 평균 타수)간의 관련성을 살펴보고 군집분석을 활용하여 각 선수들의 군집을 시도하려한다. Canonical correlation biplot is 2-dimensional plot for investigating the relationship between two sets of variables and the relationship between observations and variables in canonical correlation analysis graphically. In general, biplot is useful for giving a graphical description of the data. However, this general biplot and also canonical correlation biplot do not give some concise interpretations between variables and observations when the number of observations are large. Recently, for overcoming this problem, Choi and Kim (2008) suggested a method to interpret the biplot analysis by applying the K-means clustering analysis. Therefore, in this study, we will apply their method for investigating the relationship between skill and competition score factors of KLPGA players using canonical correlation biplot and cluster analysis.

We have investigated the excitation-light source dependence of photo-catalytic efficiency for the benzene removal. The photo-catalytic module for the benzene removal is fabricated by a combination of GaN-based ultraviolet light-emitting diode (UV GaN-LED) and $TiO_2$ thin film coated on an aluminum plate. The benzene reduction rates of 365 nm and 375 nm modules at 60 mA junction current are approximately $8.95\;\%/Hr$ and $9.2\;\%/Hr$, respectively, which indicates that 365 nm GaN-LED is more effective than 375 nm GaN-LED. The benzene reduction efficiency is also noticeably dependent on the excitation wavelength and excitation-light power, as well as it is increased with the shorter wavelength and higher excitation power. This result exhibits that UV GaN-LED is useful to remove the volatile organic compounds (VOCs) existing in the environment.

한국 제조업의 글로벌 활동과 기술혁신 간의 관계에 대한 실증분석: 기업 유형과 지식원천을 중심으로

최용석,김기완,Choi, Yong-Seok,Kim, Ki-Wan 한국개발연구원 2013 韓國 開發 硏究 Vol.35 No.2

본 논문은 수출활동 및 다국적기업화 등 기업의 글로벌 활동과 다양한 혁신성과 간에 존재하는 양의 상관관계가 한국 기업 데이터상에서도 존재하는가, 그리고 만일 그러한 상관관계가 존재한다면, 글로벌 활동 유형별로 혁신성과를 창출하는 데 있어 어떠한 요소가 중요한가에 대한 실증분석을 목적으로 한다. 본 논문의 실증분석 결과는 다음과 같이 요약된다. 첫째, 외국 다국적기업의 국내지사의 경우 혁신활동을 수행함에 있어 주로 기존 지식을 활용하는 데 반해 국내 수출기업 및 국내 다국적기업의 모기업의 경우에는 기존 지식의 활용뿐만 아니라 새로운 지식에 대한 투자(직접적인 R&D 활동)를 통해 혁신성과를 창출하고 있다. 둘째, 공정혁신을 수행함에 있어서는 주로 기존 지식의 활용이 중요한 요소인 데 반해 제품혁신을 수행함에 있어서는 새로운 지식에 대한 투자와 기존 지식의 활용이 모두 동일한 정도로 중요한 요소인 것으로 나타난다. 이러한 결과는 한국에 있어 기업의 혁신성과를 높이기 위해서는 새로운 지식에 대한 투자를 활성화시킴과 동시에 기업들이 기존 지식에 대해 보다 높은 접근성을 가질 수 있도록 하는 것이 중요함을 의미하며, 따라서 이 두 가지 요소를 모두 포괄하는 정책방향을 견지할 필요가 있음을 시사한다. In this paper, we analyzed whether there exists positive relation between firm's global activity and various innovation output and, if it exists, what are the major factors by which innovation outputs can be generated, focusing on the different degree of global activity. We found that for foreign MNC affiliates, their superior information access to existing knowledge is much more important and for non-MNC exporters and domestic MNC parents not only access to existing knowledge but also active investment in new knowledge is important. When we analyze the product and the process innovation separately, we found that for the process innovation information flows from existing knowledge is relatively more important while for product innovation investment in new knowledge and information flows from existing knowledge are almost equally important. Thus in Korea policies that promote both direct R&D activities and information flows should be pursued at the same time to enhance firms' innovativeness.

시설잎들깨 들깨잎말이명나방(Pyrausta panopealis)의 경제적 피해수준 및 요방제 수준

최용석,박덕기,윤여욱,황인수,신선미,최광렬,Choi, Yong-Seok,Park, Deok-Gi,Yun, Yeo-Uk,Hwang, In-Su,Shin, Sun-Mee,Choe, Kwang-Ryul 한국응용곤충학회 2008 한국응용곤충학회지 Vol.47 No.2

들깨잎말이명나방(Pyrausta panopealis)은 잎들깨의 주요해충이다. 피해양상은 유충이 들깨신초 부위에서 거미줄을 치고 가해하는 양상을 보이며 심할 경우 대를 끊어 놓아 더 이상 수확을 할 수 없게 만든다. 이러한 들깨잎말이명나방의 경제적 피해수준과 요방제 수준 평가를 시설하우스에서 수행하였다. 다른 해충들의 피해를 피하기 위하여 망사케이지를 이용하여 시험구를 격리시켰다. 들깨잎말이명나방 유충의 접종밀도는 발생초기 100개의 잎들깨를 처리구로하여 100주당 $1{\sim}20$주에 주당 2마리씩 6월 13일에 접종하였다. 6월 23일까지 피해주율, 피해엽수은 증가하였으나 반면에, 6월 23일 이후에는 증가하였다. 수확량 또한 동일한 결과를 보였다. 시장가격에 대한 나방 방제비용의 비율로 계산된 경제적 손실 시점은 4.0%였다. 이때의 경제적 피해수준은 100주당 유충 5.1마리였으며, 경제적 피해수준은 80% 수준에서 설정된 요방제 수준은 100주당 유충 4.1마리였다. Pyrausta panopealis is the major pest in green perilla. The larva weaves a web on the shoot of green perilla and damages. In case of extreme, The larva cuts the main branch of green perilla and the leaf of green perilla isn't harvested anymore. A field study was conducted to estimate economic injury levels (EILs) and control thresholds (CTs) for P. panopealis injuring green perilla in green-houses. Different densities of P. panopealis ranged from 1 to 20 crops (2 units per crop) per 100 crops on 13. June, early inoculation. The number of injured leaf and the rate of injured crop were increased by 23. June, on the other hand were decreased after that day. Also, the amount of yield sow the same result above. The economic loss time calculated by the ratio of cost managing this moth to market price (C/V) (C: cost managing a moth, V: Market price) was 4.0%. The economic injury level was 5.1 larval per 100 crops. The control thresholds calculated by 80% level of economic injury level was 4.1 larval per 100 crops.

경제특구 입주 외국인투자기업의 성과 분석

최용석,송영관,Choi, Yong-Seok,Song, Yeongkwan 한국개발연구원 2015 KDI Journal of Economic Policy (KDI JEP) Vol.37 No.-

To attract more FDI inflows, the Korean government has designated several special economic zones (SEZs), offering various advantages and support to the FDI. There is, however, a shared acknowledgement that those efforts have gained little reward. In this regard, this paper empirically analyzes company-level performances of labor productivity, operating profit ratio, propensity to invest and innovate, etc. and then conducts regression analysis and PSM analysis to see whether these performances are meaningfully different between foreign-invested firm and domestic firm and between foreign-invested firms. The main findings of this paper are as follows. First, in the aspects of labor productivity and operating profit ratio, no empirical evidence was found to support the hypothesis that foreign-invested firm outperforms domestic firm in efficiency and profitability, Second, in the aspects of propensity to invest, foreign-invested firms in foreign investment zones outperformed domestic firms. Third, in the aspect of R&D investment, overall, foreign-invested firms showed a stronger propensity to invest than domestic firms, but there is no empirical evidence that high propensity to invest was driven by the policy on special economic zones. In the aspect of investment in educational training, empirical evidences were found that the role of foreign-invested firms outside the special zones turned out to be the strongest and that among firms inside special zones, it was those in the free economic zone that outperformed domestic firms. Lastly, foreign-invested firms showed a stronger propensity to employ than domestic firms, but there is no empirical evidence that high propensity to employ was driven by the policy on special economic zones. 한국정부는 FDI 국내 유치를 위해 외국인투자에 특례와 지원을 제공하는 경제특구를 도입하였으나 성과가 미흡하다는 문제의식이 존재한다. 따라서 본 논문에서는 실증분석을 통해 노동생산성, 영업이익률, 투자성향, 혁신성향, 고용성향 등의 기업단위 성과가 경제특구에 입주한 외국인투자기업과 국내기업 간에, 그리고 외국인투자기업들 간에 유의한 차이를 나타내고 있는지를 회귀분석과 PSM 분석을 통해 살펴보았다. 본 논문의 주요 결과는 다음과 같다. 첫째, 노동생산성 및 영업이익률 측면에서 살펴보았을 때 외국인투자기업들이 국내기업들에 비해 효율성 및 수익성에 있어 더 높은 성과를 나타낸다는 가설을 지지할 실증적 증거는 발견할 수 없었다. 둘째, 투자성향에 있어서는 외국인투자지역에 분포한 외국인투자기업들이 국내기업들에 비해 높은 투자성향을 보였다. 셋째, 연구개발투자 측면에 있어 외국인투자기업 전체적으로는 국내기업에 비해 높은 투자성향을 보인 것으로 나타나나 이것이 경제특구정책에 의한 것임을 나타내는 실증적 증거는 존재하지 않는다. 교육훈련투자에 있어서는 비특구 외국인투자기업의 역할이 가장 크며, 특구지역 중에서는 경제자유구역에 위치한 기업들의 교육훈련투자가 국내기업들보다 더 높다는 실증적 증거가 발견되었다. 마지막으로 고용성향에 있어서는 외국인투자기업들의 성과가 더 높았으나 이것이 경제특구정책에 의한 것임을 나타내는 실증적 증거가 존재하지는 않았다.
