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. Most of all, his intelleelual capability functioned them possibly to obtain the objective viewpoint, and consequently caused the postwar reality to be diagnosed fundamentally. These attitude of recognition on the reality of the postwar writer is closely related with the Korean War which is the direct and indirect background of it. This is proved by the fact that the Korean War was ironically functioned as the abundant material source of the postwar<br/> literature by showing the ever most tragic phases than any other disaster of <me-race country.<br/>

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.

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.

신육성 다수확 밀 익산370호의 원맥과 밀가루의 품질 특성

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.

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.

꽃노랑총채벌레는 꽃을 선호하며 국화의 주요해충이다. olfactometer를 이용하여 국화가 꽃노랑총채벌레를 유인하는 트랩식물로서 효용가치가 있는지를 조사하였다. 유리온실에 심겨져 있던 스텐다드국화의 화색별 꽃노랑총채벌레의 밀도를 타락법을 이용하여 조사한 결과, 개화시기의 경우에는 핑크색, 흰색, 노랑색의 꽃에서 각각 18.4, 56.6, 52.6 마리였고, 잎에서는 7.8, 16.6, 15.4 마리가 채집되었다. 꽃봉오리 형성시기의 경우에는 꽃봉오리에서 15.2, 45.8, 41.6 마리, 잎에서는2, 8.8, 3.4 마리였다. Y-tube olfactometer 시험에서 선호하는 쪽으로 향하는 꽃노랑 총채벌레의 수는 노랑색에 대하여 빨강색, 보라색, 흰색 꽃의 후각반응을 조사한 결과, 분명한 차이가 없었다. 4-way olfactometer 시험의 경우, 냄새와 동일한 시각자극이 주어졌을 때 꽃노랑총채벌레의 빈도수는 빨강색(1.3), 보라색(3.7)흰색(2.0) 보다 노랑색(10.7)을 선호하였고, 후각적 자극이 교란된 시각적 반응에서도 빨강색 (3.3), 보라색 (1.3), 흰색 (3.0) 보다 노랑색 (10.0)을 선호하였다. 노랑색의 시각적 자극만 제외하고 다른 꽃의 시각적인 자극과 동일한 후각적 자극을 주었을 경우에는 빨강색 (4.7), 보라색 (4.7), 노랑색 (2.0) 보다 흰색(8.3)을 선호하였다. 꽃노랑총 채벌레는 꽃이 개화하기 전에는 꽃의 후각적인 자극에 먼저 반응하여 꽃봉우리로 이동하고 개화되었을 때에는 꽃의 색깔에 더 잘 반응하여 노랑색꽃을 선호하는 것으로 보아 후각적인 자극보다는 시각적인 자극에 더 잘 반응하였다. Frankliniella occidentalis is attracted to flowers and is a major pest of chrysanthemums. Even when some chrysanthemum plants are not flowering, the ones that have already flowered attract F. occidentalis. Therefore, we investigated the efficacy of chrysanthemum as a trap plant that attract F. occidentalis by using an olfactometer. The numbers of F. occidentalis collected from the flowers of pink, wihte and yellow standard chrysanthemums on a tray with wet paper during the flowering period were 18.4, 56.6, and 52.6 respectively; the numbers of F. occidentalis collected from leaves were 7.8, 16.6, and 15.4 respectively. the numbers of F. occidentalis collected from the buds of pink, white and yellow standard chrysanthemums were 15.2, 45.8, and 41.6 respectively; the numbers of F. occidentalis collected from the leaves were 2, 8.8 and 3.4 respectively. In the Y-tube olfactometer test, the number of F. occidentalis attracted to the 2-way arms of the Y-tube was not significantly different for the yellow, red, violet and white flowers. In the four-choice olfactometer test, when the same visual cues and odor cues were provided, the frequency of F. occidentalis was higher in the yellow (10.7) flowers than in the red (1.3), violet (3.7) and white (2.0) flowers. When visual cues with disturbed odor cues, F. occidentalis preferred yellow (10.0) color over red (3.3), violet (1.3) and white (3.0) colors. When the same visual and odor cues, except for yellow visual cues, were provided, F. occidentalis preferred white (8.3) color over red (4.7), violet (4.7) and yellow (2.0) colors. Therefore, F. occidentalis were attracted to buds before the flowering of chrysanthemum plants and attracted to yellow flowers after the flowering.

COMETS위성을 이용한 ETRI의 Ka-대역 전파 전파 측정 연구

최용석,이주환,김양수,Choi, Yong-Seok,Lee, Joo-Hwan,Kim, Yang-Su 통신위성우주산업연구회 2000 Joint Conference on Satellite Communications Vol.2000 No.-

본 논문에서는 CRL-NASDA와 공동연구로 ETRI에서 비정지궤도 위성인 COMETS의 Ka-대역 비콘 신호를 측정하고, 수신된 데이터를 이용하여 시간, 거리 및 고도각의 변화에 따른 전파전파 특성에 대하여 분석하였다. 분석 결과 맑은날의 거리 변화에 따른 전파전파 특성은 자유공간 손실이 중요한 영향을 미치고 있으며, COMETS위성의 고도각이 40도 이상에서 주로 측정하므로서 고도각에 따른 신호 강도 변화는 거의 나타나지 않았다. 실제 예측치보다 전송로상의 신호감쇠가 크게 측정되었으며, 강우시에 신호의 변동량이 더욱 심하여 앞으로 고속 광대역 위성통신망의 링크 설계 시에 고려하여야 할 것으로 사료된다. The rapid growth of satellite services using higher frequency bands such as the Ka-band has highlighted a need for estimating the combined effect of different propagation impairments. In this paper, propagation characteristics are analyzed under the rain condition of the Korea based on the measurements for Ka-band beacon signal of COMETS that moves in non-geostationary orbit. It is also presented that radio propagation characteristics varying as time, range, and elevation angle. As results, it is concluded that free space loss is a major parameter to the radio propagation characteristics varying as a range in clear sky. In addition, the effect of elevation angle is negligible because COMETS is observed above 40 degree. The beacon signal level of COMETS in rain condition fluctuates much more than that of COMETS in clear sky.

행렬도에서 군집분석의 활용

최용석,김형영,Choi, Yong-Seok,Kim, Hyoung-Young 한국통계학회 2008 Communications for statistical applications and me Vol.15 No.1

행렬도 (biplot)는 이원표 자료행렬 (two-way data matrix)의 행과 열을 그래프에 동시에 나타내어 이들의 관계를 살피려는 다변량 그래프적 분석기법이다 (Gower와 Hand, 1996; 최용석, 2006, 1장). 그래프적 분석기법은 그 특성상 대용량 자료를 해석하는 데는 어려움이 따른다. 따라서, 자료를 효과적으로 줄일 수 있는 군집분석을 활용하여 원자료와 변수간의 행렬도가 아닌 각 군집과 변수간의 행렬도 분석을 수행함으로써, 기존의 행렬도에서 해석의 어려웠던 대용량 자료에 대한 해석이 가능하게 되며, 자료에 대한 정보를 쉽게 파악할 수 있는 장점을 가진다. Biplots are the multivariate analogue of scatter plots. They approximate the multivariate distribution of a sample in a few dimensions, typically two, and they superimpose on this display representations of the variables on which the samples are measured(Gower and Hand, 1996, Chapter 1). And the relationships between the observations and variables can be easily seen. Thus, biplots are useful for giving a graphical description of the data. However, this method does not give some concise interpretations between variables and observations when the number of observations are large. Therefore, in this study, we will suggest to interpret the biplot analysis by applying the K-means clustering analysis. It shows that the relationships between the clusters and variables can be easily interpreted. So, this method is more useful for giving a graphical description of the data than using raw data.

벤젠제거에 대한 광촉매 효율의 여기광원 의존성

최용석,김성진,한영헌,유순재,이은아,김학수,김송강,Choi, Yong-Seok,Kim, Seong-Jin,Han, Young-Heon,Yu, Soon-Jae,Lee, Eun-Ah,Kim, Hak-Soo,Kim, Song-Gang 한국전기전자재료학회 2005 전기전자재료학회논문지 Vol.18 No.6

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.
