<Kafka>의 《流形地》 硏究

朴範緖 群山大學校 1985 論文集 Vol.11 No.-

Anfang Oktorbor 1914 schrieb Franz Kafka die Erzahlung 《In der Strafkolonie》, und las sie am 2. Dezember 1914 seinen Prager Freunden vor. Am 28.7.1914 war aber der 1. Weltkrieg ausgebrochen. Diese Erzahlung unterscheidet sich in ihrer epischen Form auffallig von anderen Werken Kafkas. Hier gibt es namlich durchaus den auβerhalb stehenden, aus der Distanz des Beobachters berichtenden, und sogar reflektierenden oder kommentierenden Erzahler, der sonst in Kafkas Epik keinen Platz une keine Funktion hat. Hier fehlt also die sich im Innenleben des Helden grudende, einheitlich einsinnige Erzahlperspektive. Ja, es fehlt uberhaupt eine eindeutige Hauptgestalt in dieser Geschichte. Wie in den anderen Werken des Dichters geht es auch in dieser Erzahlung um die fur ihn zentrale Frage von Schlud, Gericht und Strafe. Diese Erzahlung ist ein allegorisches Marchen und parabolische Erzahlung, mit Vorgangen in der wirklichen Welt verbunden und Grund-befindlichkeiten des menschlichen Daseins erhellend.

<카프카>의 <訴訟> 硏究 : 罪의 問題를 中心으로

朴範緖 群山大學校 1986 論文集 Vol.13 No.-

Kafka war nicht nur von Freud, sondern auch von Kierkegaard beeinfluβt. Auch in seinem Werke handelt es sich bei der Struktur des Gott-Mensch-Konflikts um dieselbe des Vater-Sohn-Konflikts. In diesem Ausatz habe ich meine Aufmerksamkeit auf das Problem "die religiose Schuld" gerichtet. Joseph K. versuchte vergebens zu beweisen, daB er unschuldig war. Aber endlich akzeptierte er, daB die Schuld zweifellos ist. Er verzichtete auf sein Leben und ergab sich gern dem Absoluten wie ein Hund. Beim Christentum erscheint Christus zwischen dem Absoluten und den Menschen. Doch bei Kafka gibt es keinen Christum, sondern nur Tod. Josph K. scheint durch dem Tod erlost zu werden.

<카프카>의 작품 <城>에서 불안의 문제

朴範緖 群山大學校 1994 論文集 Vol.21 No.-

In der vorliegenden Arbeit wird die Angst in F.Kafkas Roman "das Schloβ" behandelt. Die Angst ist hier bestimmt durch den Zusammenhang mit etwas Groβem, Ungeheurem, Machtigen, das seinen inneren Gesetzen nach unbekannt, nicht uberblickbar, unbestimmt ist und dessen Richtung auch nur Unbestimmtes weist. Im Allgemeinen laβt sich in den Werken Kafkas frei gewordene, offene Angst feststellen. Der Held bleibt dann entweder in ihr stecken oder findet einen Ausweg aus ihr, welcher seinerseits als wirklicher Ausweg in einen neuen Beziehungszusammenhang in die Angstbefreing fuhrt oder aber bloβ zu einer neuen Angstquelle wird. Im Werk "das Schloβ" aber nun bricht die Angst nicht auf, dafur bleiben aber die Menschen dieses Romans in der standigen Abwehr gegen sie blind und unfrei ihren eigenen Vorstellungen und Zielen verhaftet, ohne offene Beziehung mit den weiteren Bereichen um sie herum, in deren Zusammenhang sie sich ja eigentlich befinden, herzustellen. In diesem Werk erscheint die Angst, gerade indem sie gar keine unmittelbare Bedeutung erhalt, indem sie eigentlich gar nicht thematisiert wird und so gewissermaβen fehlt, deutlicher als in den anderen Werken des Dichtersals eine Zwischenstufe zwischen zwei Bereichen, zwischen zwei Lebensweisen, deren Vermeidung mit der gleichen Entwicklungs-und Entfaltungslosigkeit bezahlt wird, wie wenn man in ihr selber steckengeblieben ware. Gerade, well sie hier uberall vermieden wird, zeigt sich, daβ sie gewagt werden muβte, damit jemand uberhaupt je von der Gefangenschaft in ihr, von seinem eigenen Schutzbau gegen sie frei werden und zu offeneren, wirklicheren hintergrundigeren Dimensionen gelangen konnte. Dadurch nun erscheint die Angst deutllcher als je nicht nur negative als etwas zu Vermeidendes, sondern auch postive etwas, dessen offene Begegnung allein zu echteren Daseinsweisen hinfuhrt. Wohl zeigt sich in Kafkas Auseinandersetzung mit Machtgestalten deutlich eine Entwicklung an, welche sich auch im Verhalten gegenuber der Angst ausdruckt und die, nebenbei gesagt, die haufig vertretene Ansicht der Entwicklungslosigkeit im Werk dieses Dichters insofern modifziert, als zwar stets verwandte Themenbereiche und Probleme umkreist werde, der Gesichtpunkt aber, aus dem heraus sie dargestellt sind, und die Art und Weise, wie sich der Dichter und seine Helden zu ihnen verhalten, einer entschiednen Wandlung unterworfen sind. Die Bereitschaft zum absoluten Selbstverzicht, zur vorbehaltlosen Hingabe an die starkere Macht schwindet und wird durch die sich allmahlich immer starker durchsetzende Selbststandigkeit uberlagert.

서울 지역 여자대학교 집단에서 월경전기 증후군 및 월경전 불쾌기분장애의 유병율

정범석,이철,이지현,서민경,한오수,김창윤 大韓神經精神醫學會 2001 신경정신의학 Vol.40 No.4

연구목적 : 가임기 여성의 75%가 하나 이상의 월경전기 증상을 경험하며, 일상생활에 지장을 주는 경우도 3∼8%에 이르지만 한국 여성을 대상으로 한 월경전기 증후군(Premenstrual syndrome : PMS)및 월경전 불쾌기분장애((Premenstrual dysphoric disorder : PMDD)에 대한 역학 조사는 부족한 실정이다. 따라서 본 자들은 한국에서의 유병율, 증상의 양태 및 삶에 미치는 정도 등의 역학 조사를 통해 월경전 불쾌기분장애에 대한 올바른 정보를 제공하고 관련 임상 연구의 기초자료로 활용하고자 본 연구르 시행하였다. 방 법 : 6개의 서울 소재 4년제 여자대학교에서 무작위 군집표본 추출로 선택된 4개 학교의1∼3학년 학생 중 무작위 군집표본추출을 통해 선택된 1419명을 대상으로 하였다. DSM-IV진단기준을 근거로 저자들이 제작한 6점 척도의 설문지가 사용되었으며, 난포기에 비해 황체기에 75%이상 악화된 경우 증상이 있다고 판정할 경우의 월경전 불쾌기분장애의 유병율을 조사하였다. 월경전 불쾌기분장애 집단과 증상은 있으나 진단기준에 부합되지 않는 월경전기 증후군 집단으로 나누어 증상 양태, 식습관 변화, 생활에 미치는 영향 정도 등을 비교하였다. 결 과 : 부적절한 자료 198명(13.9%), 주요 신체 혹은 정신질환을 앓은 경우 등 선정 배제 기준에 속하는 경우 348명(24.5%)을 제외한 873명이 최종 분석되었다. 873명 중 월경전 불쾌기분장애의 유병율은 5.0%이었으며, 월경전기 증후군의 유병율은 83.3%이었다. 가장 흔한 증상은 월경전기 증후군 집단의 경우 신체증상(54.6%)이었고, 월경전 불쾌기분장애 집단의 경우 '지속적으로 짜증난다'(95.5%)이었다. 월경전 불쾌기분장애 집단의 88.6%에서 증상 때문에 한 달에 1∼2회 이상 일이나 공부에 지장이 초래되었다. 결 론 : 한국 여자대학생 집단이 경험하는 월경전 불쾌기분장애의 유병율과 증상 양상은 외국과 비슷하다. 아울러 월경전 불쾌기분장애 집단은 월경전기 증후군 집단에 비해 기분 증상이 더 흔하고 심하는 점에서 월경전 불쾌기분장애는 월경전기 증후권과 구별되는 하나의 질환 상태임을 시사한다. Objects : More than 75% of women have been reported to experience premenstrual symptoms and three to eight percent of them suffer from premenstrual dysphoric disorder(PMDD). But little is known about prevalence of premenstrual syndrome(PMS) and PMDD and PMS in Korean women who sttended universities at the time of survey. Methods : One thousand four hundred and nineteen subjects were randomly selected with cluster sampling methods among four women's university in Seoul. We measured the severity of premenstrual symptoms using six-point rating scale developed by the authors on the basis of the research criteria for PMDD in DSM-IV. Premenstrual worsening of symptoms was defined as increase in symptom scores of more than 75% from follicular to luteal phase score. And also, we compared characteristic symptoms, eating behaviors, and functional impairments between PMS and PMDD. Results : After excluding inadequate data according to our exclusion criteria, 873 of 1419 subjects(61.5%) were included in the estimation of the prevalence of PMS and PMDD. Each prevalence rate of PMS and PMDD was found to be 83.3% and 5.0% on the basis of 75% change method respectively. The most frequent symptom was physical symptoms such as headache or breast tenderness(56.4%) in PMS and 'felt irritable'(9.5%) in PMDD. Of the 44 subjects with PMDD, 39(88.6%) reported to have experienced the impairment in work or school at least once per month because of premenstrual symptoms. Conclusions : Our results indicate that prevalence and symptoms of PMDD in Korean university women are similar to those in western culture. The finding that mood symptoms were more frequent and severe in PMDD than in PMS implies that the former may be a disordered condition to be distinguished from the latter physiologic one.

To determine the effects of lime and phosphate on dry matter yield and mineral content in mixed sward in Cheju volcanic ash soil from October 1983 to the end of growing season in 1986 . The pH in soil was not affected by lime and phosphate applied, hut exchangeable Ca, Mg and available P were increased h y liming and phosphate levels. Average mean dry matter yield of lime plot was more increased 5% than that non-lime plot, and dry matter yield according to the phosphate (0, 20, 40, 60 kg/10a) applications were significantly increased 488.3kg. 1,024kg, 1,137.0 kg and 1,202.2 kg, respectively. Botanical composition in non-phosphate plot was dominated by Red top but Ladino clover was almost disappearanced However, phosphate applied plot were dominated by Orchard grass and lading clover 50-60 % and 15-20 %, respectively. Mineral (P, K, Ca, Mg) content in herbage were not different between lime and non-lime plot. But P, Ca and Mg were increased according to the phosphate levels.

박현서,안길영,신범철 韓國體育大學校附屬 體育科學硏究所 1996 韓國體育大學校附屬 體育科學硏究所論文集 Vol.15 No.1

The purpose of this research was to analyze the content of 50 wrestling games in case of stand technique and ground technique. The subjects were 100 Greco-Roman style wrestlers classified by weight who took part in wrestling world championship match and korean championship selection match in 1994. The frequency of skill trial and skill success according to different weights and different weight classes(the light weight class, the middle weight class, and the heavy weight class) were recorded cumulatively in check-list form. Their mean and standard deviation(mean±SD) were calculated. χ² verification was applied to the frequency of significance items and one-way ANOVA to score and score rate. The results are as follows ; 1. Conclusion 1) The results of χ² and ANOVA verification had a significant difference among skill variants according to different weights (1) The mean and standard diviation and χ² verification of skill frequency shows that there is statistically significance in case of SS1(χ²=54.1) in stand technique and GS1(χ²=42.2) in ground technique. (2) in verification of skill success, only SS1 in stand technique shows statistically significance(x2=17.8), but ground technique shows no significance among different skills. (3) The ANOVA of 1 game scoring indicates that there are significance in case of SS1, SS2, SS5, SS7, SS8, SS9 in stand technique and GS2, GS4 in ground technique. (4) From ANOVA of success rates according to different skill types, it is showed that only GS4 shows statistical significance x2=20.0 in ground technique, but there is no significance among other skills in ground technique and among skills in stand technique. (5) In ANOVA of score rae according to skill types, SS1 in stand technique has statistically significance but ground technique shows no sigmificance among skills. These results indicate that score rate of stand technique is higer that of ground technique. (6) In verification of skill trial according to different skill classes(skills in stand technique and skills in ground technique), neither stand technique nor ground technique. (7) In verification of skill trial and success according to different skill classes, ghere is no significance between stand technique and ground technique. (8) ANOVA of scoring according to different sill classes also shows no significance between stand technique and ground technique. 2) The results of x2 and ANOVA verification of skill variants according to defferent weight classes(the light weight class, the middle weight class, and the heavy weigt class) (1) The verification of skill trial tells us that SS1(x2=16.7), SS2(x2=17.5) have statistically significance in case of stand technique and GS2(x2=23.4), Gs5(x2=12.83) in case of ground technique. (2) In ANOVA of skill trial, only SS1 in stand technique shows statistically significance but there is no significance among other skills in stand technique and among skills in stand technique. (3) In ANOVA of scoring accoding to skill types, SS1, SS2, SS5, SS7, SS8 show statistically significance in stand technique and GS2, GS5 in ground technique. (4) In verification of skill trial according to different skill classes(Skills in stand technique and skills in ground technique), there is no significance between stand technique and ground technique. (5) Verification of skill succes according to different skill classes shows no significance between stand technique and ground technique. (6) ANOVA of scoring according to different skill classes also shows no significance between stand technique and ground technique. 2. Suggestion 1) Score rates are higher in ground technique than in stand technique, so coaches should take it into cosideration when they distribute the two techniques. 2) Study about spiritual strength in terms of wrestling is required. 3) In skill coaching of Greco-Roman style Wrestling, it is suggested that coaches direct various skills by small skill-centred approach to get ground technique rather than high scoring by big skill-centred approach. 4) It is required to develop prograns that will characterize progessional weight and professional skills.
