This dissertation aims to investigate the alienation phenomenon in present-day American society and its solutions by studying the human relationships in Sam Shepard's Buried Child(1978) The perception of these problems and the theme in Buried Child are clearly represented in Shepard's view of humanity and in the reciprocal relationships between the characters in this work. The kind of human relationships that Shepard endeavors to treat in his work are the ones between father and sons, i.e between Dodge, Tilden and Bradley; the one between man and woman, i.e. between Dodge and Halie, Vince and Shelly; the finally, the relation between brothers, that is between Tilden and Bradley. The contents and discussion which are treated in this dissertation through these human relationships are summarized as follows: First, The point of view through which Shepard looks at family and at society is one which reflects them as societal units seeking to expand their ranges by gradually linking or connecting personal unhappiness to family unhappiness, and family unhappiness to social unhappiness. Second, in the relationship between father and sons, the destruction and dissolution of Dodge's family begins when Dodge drowns the child born of incest between Halie and Tilden and buries the child in the back yard. The relationship between Dodge and Tilden is lacking in love and each is absorbed in his or her own isolated world. Still, their relationship is friendly, and communicative when necessity demands that they relate strongly to each other. In the relationship between Dodge and Bradley, does not Bradley stand only for the meanness of Dodge's family and/or the indirect penalties they pay for that meanness, he also becomes a challenger and usurper of Dogde's paternal rights by committing an immoral act himself. The extreme hostility, which results between Dodge and Bradley, shows how serious the absence of love is. In the relationship between man and woman, the expressive basis of unhappiness is the lack of love which results in an alienation so profound that it disregards all else. This problem may be solved, Shepard suggests, if man and woman can use love as a basis for understanding and forgiveness. Also, in the relationship of brothers, the absence of love and its relationship to cold-heartedness in humanity are also explored. Bradley is hostile to his brother Tilden, because of the potential for jealousy toward Tilden. Tilden and Bradley are alienated by an illusion of their dead brother, Ansel, and by the mental and physical deformities of Tilden; futhermore, Bradley proves to be a pathological phenomenon created by American society. Finally, Shepard's characters in his drama are at the mercy of unavoidable circumstances which encircle them and cause them to despair of and to feel abandoned by fate when confronted by their attempts to escape reality. But in the second of the drama, Shepard, on the contrary, tries to find a solution which will allow and provide for new lives for human beings; consequently, his characters in this drama recognize the need of an reciprocal relationships, and are reconciled with each other. At any rate, Shepard finally restores humanity to human beings and empasizes the necessity of love throughout all stages of alienation in human development.

Trace levels of inorganic and organic mercury ions in aqueous solution were concentrated on several ion exchange resins and their distribution coefficients were found by Cold Vapor Atomic Absorption (CVAA) technique. Of ion exchange resins used for experiments, moderately basic anion exchange resin (Cl^--from, Dowex-2 2×8-100) showed the best distribution coefficient, resulting in the effective concentration of mercury ions. Also, better distribution coefficients were obtained for highly crosslinked in exchange resins. As the temperature of mercury solution increased the amount of the mercury ions absorbed on the resins increased. Inorganic and organic mercury ions were selectively reduced by SnCl_2, NH_2OH·HCl and NaBH_4, respectively, and SnCl_2, NH_2OH·HCl showed a better results for inorganic mercury and NaBH_4 for organic mercury. Although the addition of NaBH_4 to solutions containing mercury ions as a reducing agent showed high absorbances, it did not obey Beer's law satisfactorily when the concentration became high. With the aid of HNO_3 and NH_4Cl sobution, sobutions containing both types of mercury could be preserved for more than a week. In solutions with inorganic and organic mercury ions, inorganic mercury ions were selectively determined by SnCl_2, NH_2OH·HCl. The organic mercury content of the solution could be determined after total mercury and inorganic mercury were analyzed separately.

꿀벌의 독액으로부터 분리된 ME은 강항 항균활성을 가지나, 진핵세포에 대하여 세포독성 활성을 포함하고 있다. 본 연구에서는 구조와 항진균활성과 상관관계를 검토하며, 세포독성을 가지지 않으며 보다 강한 항진균활성을 가진 펩타이드의 디자인하기 위하여, ME와 CA 또는 MA으로 이루어진 hybid 펩타이드인 MA(10-17)ME(1-12) 및 CA(1-8)ME(1-12)을 고상합성법의 의하여 합성 하였다. CA(1-8)ME(1-12) 및 MA(10-17)ME(1-12)는 인간의 적혈구에 대하여 용혈현상을 나타내지 않으며, Fusarium oxysporum에 대하여 ME 만큼의 강한 항진균활성을 나타내었다. 또한 이들 hybrid 펩타이드는 (1,3)-β-D-glucan synthase의 활성을 강하게 억제하였다. 이 결과는 Fusarium oxysporum에 대한 hybrid 펩타이드의 활성은 균의 세포벽의 합성의 억제에 의한 것과 관련성이 있는 것을 시사한다. 또한 본 연구의 결과는 세포독성을 가지며 강한 항진균활성을 가지는 펩타이드의 설계에 기초를 제공하였다고 생각된다. Melittin (ME) from honeybee venom has a broad range of strong antimicrobial activity, but it has hemolytic activity against eukaryotic cells. In order to design peptides with powerful antifungal activity without cytotoxic property of ME and understand structure-antifungal activity relationships, the hybrid peptides derived from the sequences of ME and cecropin A (CA) or magainin 2 (MA), MA(10-17) ME(1-12) and CA(1-8)ME(1-12), were synthesized by solid phase method. MA(10-17)ME(1-12) showed potent antifungal activity comparable to ME against Fusarium oxysporum with no hemolytic activity against human red blood cells. The hybrid peptides showed strong inhibition of (1,3)-β-D-glucan synthase. This result indicates that the antifungal activity of the hybrid peptides against Fusarium oxysporum is attributed to the inhibition of cell wall synthesis. The results therefore showed a successful design of a peptide having antifungal activity without hemolytic property.

물관리방법을 달리한 상시담수와 간단관개에서 메탄과 아산화질소의 배출 양상과 서로 다른 종류의 유기물원 및 질소비료 시용에 따른 메탄과 아산화질소 배출을 비교하고 저감 할 수 있는 방법을 찾기 위해 본 시험을 실시하였다. 물관리방법으로는 상시담수 (이앙∼출수 35일까지 담수)와 이앙 35일 이후 중간낙수한 간단관개 (중간낙수기간 20일),그리고 시비방법으로는 토양을 검정한 시비량인 토양검정, 토양 검정시비량+볏짚 돈분액비, LCU 완효성비료 그리고 N을 시용하지 않은 대조구 등을 처리하여 메탄 및 아산화질소 배출량을 측정하였다. 메탄 배출량은 간단관개보다 상시담수에서 높았고, 아산화질소 배출량은 이와 반대로 나타났다. 유기물과 비료시용 종류에 따른 메탄과 아산화질소 배출량은 액비와 검정시비+볏짚시용구에서 가장 높았으며, LCU 완효성비료구에서 가장 낮았다. 지구온난화잠재력으로 환산한 온실가스 배출은 물관리 조건에서 상시담수가 간단관개보다 170∼208% 높았으며, 요소를 시용하고 상시담수를 기준 한 것과 간단관개로 물 관리하여 각 처리에 따라 온실가스 배출을 비교하면 요소는 41.4%, LCU 완효성비료 55.8%로 온실가스 배출을 줄일 수 있는 것으로 나타났다. 그리고 비료이용효율은 LCU완효성비료, 액비>검정시비+볏짖>검정시비 순이었다. Emission of methane and nitrous oxide affected by nitrogen fertilizer materials were measured simultaneously in rice paddy fields under flooding and intermittent irrigation in 2000. Studies focused on mitigating CH_4 emission from rice paddy fields are summarized and the possibilities and limits applied to world's rice cultivation are discussed. The mitigation options are water management, soil amendments, organic matter management, different tillage, rotation, and cultivar selection. Altering water management, in particular promoting midseason aeration by short-term drainage, is one of the most promising strategies, although these practices may be limited to the rice paddy fields where the irrigation system is well prepared. The test site was divided into two water managements: a continuously flooded plot which was maintained flooded by constant irrigation from May to September, and an intermittently drained plot in which short-term (20days) draining practices were performed one times during the flooding period. By total emission of GHGs converted by global warming potential (GWP), flooding plots were higher 170~208% than intermittent irrigation plots. For emission of GHGs in fertilizer materials, it was high in the order of Swine slurry>Urea+Rice straw>Urea>LCU. Basing on GHGs emission of urea fertilization under flooding as baseline GWP of urea fertilization and Latex-coated urea under intermittent irrigation showed lower GHGs emission by 41.4% and 55.8%, respectively. In this case fertilizer use efficiency (kg unhulled rice/kg of applied N) were 18.2~20.2 and 18.7~19.0 and 9.3 and 5.8~6.6 for Swine slurry and LCU and Urea+Rice straw and Urea in the continuously flooded and intermittently drained plot.

Study on Method of Sperm Aspiration and Injection into an Oocyte in Intracytoplasmic Sperm Injection(ICSI) Immobilization of spermatozoa prior to intracytoplasmic sperm iniection(ICSI) sometimes results in crooked tail and this makes it difficult to aspirate sperm into an injection pipette tail first. Head-first sperm aspiration into an injection pipette avoid this problem due to the bigger size of the sperm head. The effect of head or tail-first sperm injection into an oocyte on fertilization cleavage, percentage of grade I embryos and development to blastocyst stage in ICSI program has been studied. A single living immobilized spermatozoa from oligoasthenozoospermic patient was injected into an oocyte head-first or tail-first according to the treatment. Eighteen hours after microinjection, oocytes ware inspected for survival and fertilization Fertilized oocytes with two pronuclei were cultured in 30μl drop of mHTF supplemented with 10% heat-inactivated follicular fluid(FF) at 37℃. On day 2. embryo transfer was performed with cleaved embryos. The remaining 2-8 cell stage embryos were co-cultured with BRL cells in mHTF + 10% FF for 72 hours and the developmental stage was observed. The data were analyzed by Analysis of Variance. A total of 164 oocytes from 36 cycles were assigned to earth treatment and ICSI was performed(88 head-first, tail-first). The rates of normal fertilization were 81.8% and 76.3% for head-first and tail-first, respectively. Of the fertilized oocytes, the percentage of cleaved embryos and the percentage of grade 1 embryo among cleaved embryos were 88.9% and 68.8%, 93.1% and 74.1% for head-first and tail-first, respectively. Of the 2-8 cell embryos cultured, 44.4%(16/36) and 50.0%(10/20) for head first and tail first, respectively developed to blastocyst stage. There were no differences in fertilization, cleavage, rates of grade 1 embryos, and development to blastocyst stage. In conclusion, head-first or tail-first sperm injection into an oocyte in ICSI program does not affect fertilization and subsequent embryo development to blastocyst stage in vitro.

연구목적 : 세계적으로 널리 사용되는 우울증 척도인 the Center for Epidemiologic Studies Depression Scale(CES-D)을 이용하여 지역사회 주민의 우울증상의 정도를 평가하고, 우울증상의 위험요인을 분석하고, 한국인에서 우울증상의 요인구조를 알기 위해 본 연구를 실시하였다. 방 법 : 경기도 일 농촌 지역의 30세 이상 주민에 대해 무작위 군집 집락 추출을 실시하였고, 훈련된 면담원들이 가정 방문을 통하여 면접 및 자기보고 검사인 CES-D를 실시하였다. 총 1,315명에서 응답을 하였고 응답율은 59.3%이었다. 결 과 : CES-D에 의한 우울증 점수는 0∼5점이 57%정도를 차지하였고, 평균 점수는 남자 7.8점 여자 9.5점으로 비교적 낮은 편이었다. ANCOVA 분석 결과 비결혼, 저학력, 여성이라는 위험요인은 독립적으로 우울증상을 악화시키는 요인이었으나 연령은 통계적으로 유의하지 않았다. CES-D 결과를 요인분석을 시행한 결과 4가지 요인이 추출되었는데 우울증상 및 신체증상이 한 개의 요인으로, 다른 나라에서 보고되지 않는 정서적 고통이 별도의 요인으로 추출되었다. 결 론 : 국내 역학 조사에서도 외국과 유사한 우울점수 및 위험요인이 확인되었으나 우울증의 요인에서는 특이한 요인이 추출되었다. 한국인에 독특한 우울 반응에 관한 추가 연구가 필요하다. Objectives :The rates, correlates, and factor structure of depressive symptoms in a Korean rural sample were examined using Korean version of the Center for Epidemiologic Studies Depression Scale(CES-D). Methods : Door to door visiting survey was conducted by trained interviewers. A random cluster sample of 1,315 respondents, aged 30 and over completed the CES-D scale along with additional sociodemographic questionnaire. Results : In this sample, mean CES-D score of male and female were 7.8 and 9.5, respectively which were lower than those reported previously. Symptoms of depression were most common among the less educated, non-married and female according to ANCOVA. Age was not a significant risk factor for depressive symptoms. Different factor structures emerged from this sample as compared to other studies using this approach. Somatic symptoms and affective symptoms were combined as one factor and emotional hardship emerged as a separate factor. Conclusion : Symptoms scores and risk factors were similar to the results reported in other countries but unique factor structures were found in this study. Further research is needed about the Korean depressive symptomatology and related areas.
