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.

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.

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.

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.

2010년 충청남도 공주시 신풍면 사과원과 예산군 덕산면 블루베리 과원에서 최초로 보고된 이름 모를 날개매미충 일종은 대략 4-5년 전부터 과원에 출현하기 시작하여 급속도로 밀도가 증가한 것으로 추정된다. 날개매미충이 발견된 식물은 26종에서 관찰되었고, 주로 블루베리, 포도, 복숭아, 옻, 두릅, 대추, 키위, 복분자, 사과, 살구, 자두, 밤 이었다. 날개매미충의 산란은 주로 1년생 가지에서 이루어졌다. 사과와 자두의 1년생 가지에 산란된 난괴내 알의 평균수는 각각 18.7개와 15.3개였다. 또한 산란된 난괴의 평균길이는 각각 12.35 mm와 11.45 mm였다. 알의 평균크기는 길이가 1.2 mm 폭은 0.5 mm였다. 사과와 자두에 산란된 난괴내 알 간의 평균간격은 각각 1.3 mm와 1.5 mm로 차이를 보였으며 동일한 난괴 길이내 알의 평균수는 각각 17.1개와 13.3개로 차이를 보였다. An unknown planthopper was discovered in 2010 in an apple orchard in Sinpoong-myun, Gongju-si and in a blueberry orchard in Deogsan-myun, Yesan-gun. This pest have arrived 4 or 5 years ago and the population density then rapidly increased. It was identified as Ricania sp. by Dr. Murray J. Fletcher. Adult Ricania sp. was found on 26 plants including blueberry, grape, peach, sumac, japanese angelica, jujube, kiwi, Rubus coreanus, apple, apricot, plum and chestnut. Females lay eggs on 1-year-old branches. The mean number of eggs laid on apple and plum were 18.7 and 15.3, respectively. The mean length of egg masses on apple and plum were 12.35 and 11.45 mm, respectively. The distance between eggs laid on apple and plum branchs were 1.3 and 1.5 mm, respectively. The mean number of eggs in the same length of egg mass on apple and plum branchs were 17.1 and 13.3, respectively.

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.

시설내 토마토녹응애의 발생양상과 유기농업자재 선발

최용석,황인수,조신혁,Choi, Yong-Seok,Whang, In-Su,Jo, Shin-Hyuk 한국응용곤충학회 2016 한국응용곤충학회지 Vol.55 No.3

무가온 시설토마토 재배지내에서 토마토녹응애 발생양상은 4월 중하순경 최초로 발생하기 시작하여 6월 중하순경 최대 발생을 나타냈다. 하지만 야간기온이 낮을 경우 번식력이 증가하게 되고 주간기온이 높을 경우에는 분산이 활발해져 고온기인 7월에도 지속적으로 증가하는 것으로 조사되었다. 유기농업자재 11종에 대한 토마토녹응애의 살충독성 실내검정 결과, EOIMa (Matrin 0.6%), EOICo (Clove oil 10%)가 500배에서 각각 92.1%와 95.1%로 90% 이상의 살충효과를 보였다. 특히 EOIMa 1,000배에서는 90.4%로 90%, EOIMa 2,000배에서는 88.2%의 높은 살충효과를 보였다. 포장검정에서도 EOIMa 1,000배와 EOICo 500배는 각각 91.5%와 93.9%의 살충효과를 보여 두 약제 모두 농약을 대체하기에 충분하였고 EOIMa의 경우 2,000배에서도 살충효과가 90%에 가까웠기 때문에 예방적 활용도 가능할 것으로 판단되었다. The first occurrence of the tomato russet mite, Aculops lycopersici Massee was in mid-late April, and the maximum occurrence was in mid-late June in 2013 and 2014. However, in 2015, the density of tomato russet mites increased in July. This pattern is thought to be attributed to temperature fluctuations, in which, low temperatures at night promoted their reproduction and long periods of high temperatures during the day promoted their dispersion. Comparison of the use of 11 Eco-friendly organic insecticides (EOIs) showed that, the mortality rates after application of 0.6% matrin(EOIMa) and 10% clove oil (EOICo) were 92.1% and 95.1%, respectively, when administered at 500-fold diluted concentrations. At 1,000-fold and 2,000-fold diluted concentrations, the mortality rates of EOIMa were 90.4% and 88.2%, respectively. In a field test, the mortality rates of EOIMa at the 1,000-fold diluted concentration and of EOICo at the 500-fold diluted concentration were 91.5% and 93.9%, respectively. In conclusion, theses two EOIs are sufficient to replace pesticides, and EOIMa seems to be particularly useful as a prophylactic given that it induced a mortality rate of 88.2% at a 2,000-fold diluted concentration.
