戱曲 「山돼지」 硏究

김성진(Kim Sung-jin) 중앙어문학회 2000 語文論集 Vol.28 No.-

This dissertation deals with Kim Woo-jin's 「Wild Boar」. Kim Woo-jin became indulged in his art during his University education. What's more, he tried to express the theatre art through a sharp insight of the times and created an optimistic atmosphere for Koreans under Japanese rule. His father, Kim Sung-kyu, was a president of the 'Mokpo Literary Association' and enjoyed writing poems. He also had such a special affection for literature that he contributed lots of money to support the 'Mokpo Literary Association'. And the world of death in Kim Woo-jin's works does not mean a real death. The world suggests the death of Korea traditional and conservative customs and reflects the difficult reality to break the traditional customs. His leaving home to lead a spiritual life carried on the very important meaning. 〈Noon〉 deals with the consciousness of class and nation, and 〈Lee Young-yeo〉 criticizes the defect of masculine centered society through Lee Yong-yeo. According to 「The Disgust of Poet Dooduckee」 and 「Shipwreck」 represent Kim Woo-jin's self conscious drama and the words of disgust and wreck symbolizes Kim Woo-jin's self desire for a new world. 「Wild Boar」 represents the free society for all people and the social awareness for reform. Kim Woo-jin includes the 'Dong Hak movement' in his drama and suggests a uncompromising willingness of social revolution established by young intellectuals and himself who showed only conscious conflict within the predestined yoke of the individual. In the play he changed his dramatic techniques which brought him closer to his readers and audiences but he emphasized intellectuals' awakening in much of his work. In other way, Kim Woo-jin developed a new contemporary drama movement in Korea for the nation which might have expressed real life under Japanese colonial rule. Kim Woo-jin was the representative of Korean drama in the 1920's who lived as a poet and critic as well as a experimental playwriter. Kim Woo-jin was one of the most excellent dramatists and the forerunner of Korean modern literature who led the new theatre movement, developed Korean drama from the early literature stages of the 1920's, and established himself as a leader in Korea literature.

Objectives Body image distortion is found in eating disorder and obesity and there are some evidence that schizophrenia is associated with body image distortion. This study sought to find whether schizophrenic patients report more body image distortion than healthy individuals and whether it is related with symptomatology. Methods A total of 88 inpatients with schizophrenia and 88 healthy controls were recruited. Weight, height, and body image accuracy were assessed in all participants, and assessment of mood, psychotic symptom severity and self-esteem, and personal and social performance scale were conducted. Results The patients with schizophrenia had higher Body Mass Index (p < 0. 001) and underestimated their body size more than controls (26.14% vs. 5.13%, p < 0.001). Multiple regression analysis showed that lower depressive symptoms and higher scores of general psychopathology predicted underestimation of body size. Conclusion Weight gain and metabolic syndrome are common adverse events of pharmacological treatment of schizophrenia. Thus, underestimation of body size among patients with schizophrenia may interfere with effort to lose weight or seek weight reduction programs. Clinicians need to consider possible unterestimation of underestimation of body size in patients whose general symptomatology is severe.

Porous cordierite was synthesized by the mechano-chemical processing using fly ash. The phase evolution of cordierite was investigated as a function of processing variables such as milling time and sintering temperature. In this study, the phase transition path of cordierite from fly ash was followed by sapprine/spinel ${\to}$ mullite/spinel ${\to}{\alpha}$-cordierite. Porous cordierite fabricated after 32 h of milling time and sintering at $1150^{\circ}C$ showed relatively low thermal expansion coefficient ($2.5{\times}10^{-6}/^{\circ}C\;(25{\sim}1000^{\circ}C$)) and high porosity (75%).

약밀려남/잡아당김/급냉각의 연속적인 압출 공정을 이용하여 대면적 불화 고분자 막을 제작하였다. 제안한 방법으로 형성된 불화 고분자 박막은 $C_i=2.9\;nF/cm^2$의 전기용량밀도가 측정되었고, 1kHz에서의 ${\varepsilon}_r$=56의 높은 유전상수를 나타내었다. $1.5406{\AA}$의 파장에서 Bruker AXS X-ray 회절분석기를 통해 $18.0^{\circ}$에서 최고점을 나타내어 전기변형 성능에 적합한 ${\beta}$ 상태를 확인하였다. 본 연구는 넓은 면적의 인공근육에 응용 가능한 전기변형 불화고분자막의 새로운 박막 형성 기술로 이용될 수 있다. Polymer electrostrictor materials can exhibit high electroactive strain and hold increasing promise for a variety of actuator applications. The size of available actuators has been limited, however, by the solution-based casting and annealing process generally required to prepare electrostrictor actuator materials. We report on a high throughput melt and stretch extrusion process capable of creating large sheets of an electrostructive terpolymer, poly (vinylidene fluoride-trifluoroethylene-1, 1-chlorofluoroethlene) while producing a suitable crystallinity and crystal phase for high strain electrostrictor performance such as artificial muscle systems.

김성진,이상호,방지환,Kim, Sung-Jin,Lee, Sang-Ho,Bang, Ji-Hwan 한국정보처리학회 2002 정보처리학회논문지D Vol.9 No.5

1998년에 등장한 구글 검색 사이트(http://www.google.com)에 처음 소개된 페이지랭크 알고리즘은 웹 문서들의 연결 구조에 기반하여 문서들간의 순위를 부여하는 방법이다. 페이지랭크 알고리즘은 상용 검색 엔진에서 구현되어 사용되고 있으나, 상업상의 이유들로 인하여 구현 기법에 관한 연구 결과는 거의 발표되지 않고 있다. [4,8]에서 소개된 페이지랭크 알고리즘의 구현 기법은 웹 문서들의 페이지랭크 값을 산출하기에 충분하지 않다. 본 논문은 페이지랭크 알고리즘의 구현 기법[4,8]을 설명하고, 이를 적용하는데 필요한 입/출력 자료 구조 및 4가지 주요 구현 기술을 제시한다. 본 논문은 실제 웹 문서의 페이지랭크 값을 산출하는 시스템을 예로 들어 페이지랭크 알고리즘을 적용하는 방법에 대한 이해를 돕도록 하였다. The Google search site (http://www.google.com), which was introduced in 1998, implemented the PageRank algorithm for the first time. PageRank is a ranking method based on the link structure of the Web pages. Even though PageRank has been implemented and being used in various commercial search engines, implementation details did not get documented well, primarily due to business reasons. Implementation techniques introduced in [4,8] are not sufficient to produce PageRank values of Web pages. This paper explains the techniques[4,8], and suggests major data structure and four implementation techniques in order to apply the PageRank algorithm. The paper helps understand the methods of applying PageRank algorithm by means of showing a real system that produces PageRank values of Web pages.

김성진,Kim, Sung-Jin 한국비블리아학회 2014 한국비블리아학회지 Vol.25 No.1

본 연구는 Davis의 기술수용모형을 기반으로 대학도서관에서 제공하는 모바일 서비스 이용 의도에 영향을 미치는 요인을 파악하고자 하였다. 기술수용모형의 핵심변수인 인지된 유용성과 인지된 사용용이성을 기본으로 하되 최근 모바일 시스템에 많이 적용되는 인지된 놀이성을 추가하였으며 외부변인으로는 모바일 도서관의 유비쿼터스속성 및 상황인식성과 개인의 모바일 인터넷 자기효능감을 사용하였다. 이를 위해 대학도서관 두 곳의 모바일 도서관 접속 경험이 있는 재학생 325명을 대상으로 설문조사 하였으며 SPSS 18.0과 Amos 21.0을 이용하여 경로분석을 실시하였다. 분석 결과, 인지된 유용성이 서비스 이용의 결정적인 요인으로 나타났으며 인지된 사용용이성은 인지된 유용성을 매개로 모바일 서비스 이용에 간접적인 영향을 미치고 있었고, 인지된 놀이성은 유의한 영향을 미치지 않았다. 외부변인인 유비쿼터스속성은 인지된 유용성에 가장 큰 영향을 미쳤으며, 상황인식성은 인지된 놀이성과 인지된 사용용이성에, 모바일 인터넷 자기효능감은 인지된 사용용이성에 영향을 미쳤다. 대학도서관의 모바일 서비스 이용의도를 결정하는 영향력 있는 요인들을 파악함으로써 대학도서관 모바일 서비스 영역의 이론적 의의와 실무적 의의를 함께 고찰하였다. The purpose of this study is to identify the factors that influence users' intention to use mobile services in academic libraries, based on the Davis' Technology Acceptance Model. This study employed both perceived usefulness and perceived ease of use, which were core variables in TAM, and added perceived playfulness that was recently applied to many researches on mobile system acceptance intention. As external variables, ubiquitous ability, context awareness, and mobile internet self-efficacy were employed. The data was collected from 325 surveys from two academic libraries and was analyzed with SPSS 18.0 and AMOS 21.0. As a result, perceived usefulness was the most significant factor in predicting users' acceptance intention and perceived ease of use was an indirect determinant of service usage. But perceived playfulness was not significantly correlated. Ubiquitous ability among external variables had a significant effect on perceived usefulness, context awareness did on both perceived playfulness and ease of use, and mobile internet self-efficacy did on perceived ease of use. Based on the findings, this study discussed theoretical and practical implications in academic library mobile service area.

This study was conducted to provide basic data for policy of Oriental medicine by analyzing community resident's consciousness of taking herb medicine and its related factors. Data were collected from 1478 residents from March 2, 2001 to May 31, 2001. The results of this study are summarized as follows. 1) The rate of experience of taking herb medicine was 85.2%(88.2% of 'male'; 82.5% of 'female'). It appeared to be significantly higher in the groups of 'the married', 'housewife', and 'Buddhist'. As the age increased, so the rate of experience of taking herb medicine was significantly high. 2) In case of purpose of taking herb medicine, taking herb medicine as a restorative(66.8%) was much higher than taking it as a curative medicine. 3) 52.1% of the respondents satisfied with the effect of herb medicine. The groups of 'male', 'older age', 'residents in a big city', 'insurant in company', and 'the employed' showed significantly high rate in satisfying with herb medicine than the other groups. 4) According to the reason for preferring herb medicine, 36.7% of the respondents preferred herb medicine because the herb medicine was effective, while 27.8% preferred it because its side effect was low. 16.7% preferred it because persons around them recommended it. 5) 42.6% of the respondents did not want to take the herb medicine because the price of the herb medicine was high. Also 20.6% of the respondents did not want to take herb medicine because it is uneasy to take herb medicine. 15.8% did not want to take it because certain food should not be taken during the period of taking it. 9.4% did not want to take it because it tasted bitter. 6) In case of opinions on side effects of herb medicine, 40.8% of the respondents thinks that herb medicine is free from side effects, while 37.5% thinks that it causes side effects. There were significant difference in the opinions on side effects by sex, age, marital status, resident area, education level, occupation, and type of health insurance. 7) 60.7% of the respondents thinks the price of herb medicine is not resonable, while only 10.9% thinks it is resonable. 8) 45.2% of the respondents uses packs of decocted herbs although they think the packs of decocted herb are a little low effective because decocting herbs in home is bothersome. 45.2% uses packs of decocted herbs because they are convenient, being not related to the effect. 7.6% takes medicinal herbs after decocting them in a clay pot because they think the packs of decocted herbs have low effect. 51.9% does not know whether taking herb medicine in summer is effective or not because the effect is different according to their physical constitutions. 35.5% thinks that taking herb medicine is summer is effective because their physical stamina is weakened after sweated a lot, while 12.6% thinks that it is not effective because the effect of herb medicine disappears with sweat. 9) According to the level of satisfaction with Oriental medical care, the respondents marked $3.47{\pm}0.64$ points on the base of 5 points. It was significantly higher in the groups of 'male', 'the married, resident in a big city', 'highschool graduate', 'the unemployed', 'office clerk', 'growing up in a big city', 'insurant in region', and 'the middle class'. 10) According to the result of a regression analysis of factors influencing preference for herb medicine, the factors displayed significant difference by sex, age, education level, health status, and times of receiving Oriental medical care. As shown in the above results, the community residents satisfy with the effect of herb medicine. Therefore, the method of taking herb medicine without difficulty must be devised. The medicinal herbs in packages need to be included in health insurance coverage and resonable price of herb medicine must be set. Also, education program for community residents must be developed in order to provide right information in herb medicine. Therefore, related public authority

FOG를 이용한 디지털 진북추종 방식

김성진,Kim Sung-jin 한국정보통신학회 2005 한국정보통신학회논문지 Vol.9 No.6

FOG(fiber optic gyroscope :광섬유 자이로스코프)는 소형 경량화, 신속한 가동, 저 전력 소모 및 저렴한 가격으로 실현 가능하므로 자이로콤파스시스템에서의 선호도가 높아지고 있다. 본 논문에서는 FOG를 기반으로 하며, 자이로콤파스시스템에 적용할 수 있는 디지털 진북추종 방식을 제안한다. FOG의 earth signal의 해석모델을 분석하고, lock-in증폭기를 통과한 earth signal을 모델링 한다. 두 개의 lock-in증폭기 출력신호를 이용한 진북추종 알고리즘을 개발하고, 이 알고리즘에 의한 디지털 진북추종 방식을 제안한다. 제안한 방식의 성능을 증명하기 위해 컴퓨터시뮬레이션 결과를 포함한다. In the gyrocompass system, the use of the fiber optic gyroscope(FOG) makes this traditional system considerably attractive because it has strong points in terms of weight, power, warming-up time, and cost. In this paper, a novel digital north-finding method based upon an FOG, which can be applied to the gyrocompass system, is proposed. The analytical model for the earth signal of the FOG is described, and the earth signals passed through lock-in amplifiers are modeled. Additionally, a north-finding algorithm using two lock-in amplifier outputs is developed, and the proposed method is organized by the developed algorithm. Simulation results are included to verify the performance of the proposed method.
