핵분열생성물중의 하나인 방사성스트론튬은 임신한 쥐에서 태반을 빠르게 통과하여 태아를 오염시킨다. 독성이 적은 천연착화제로서 마우스체내의 방사성스트론튬(Sr-85)의 제거에 효과적인 것으로 알려진 카이토산을 이용하여 Sr-85의 태반오염억제에 관한 연구를 하였다. 실험군은 일반식이를 공급한 대조군과 임신 17일째에 수용성카이토산을 피하(1% 카이토산), 구강(10% 카이토산), 복강(0.3% 카이토산)으로 주사한 카이토산군으로 분류하였다. 피하주사군은 Sr-85 오염후 카이토산을 주사한 군이며 복강과 구강주사군은 Sr-85 오염젼 15일간 카이토산을 공급한 군이었다. 출산과 동시에 어린마우스의 전신을 측정한 겨러과 출생후 7일째에 대조군이 2.8 ±0.3%의 전신축적율을 나타낸 반면 피하, 구강, 복강, 주사군은 각각 1.2 ±0.1%, 1.4 ±0.1%, 1.6 ±0.2%로 나타났다. 결과적으로 임신한 마우스에서 수용성카이토산은 방사성스트론튬의 태반오염을 유의하게 억제하는 것으로 사료된다. Radiostrontium passes the placental barrier in pregnant rodents very well. Chitosan, a natural nontoxic chelator, was reported to reduce whole body retention of radiostrontium in mice. The aim of the present study was to evaluate water soluble chitosan as a blocking agent of transplacental transfer of radiostrontium in pregnant mice. Twenty pregnant mice wre divided into four groups : control and three groups of chitosan treatment(groups 1 to 3). Sr-85(15KBq in 0.2ml saline) was subcutaneously injected into pregnant mice at the 17th day of pregnancy. In control mice, 0.2ml saline was given 5 hours after the injection of Sr-85. In group 1.1% water soluble chitosan was given subcutanously for two days, twice daily after the injection of Sr-85. In group 2, 10% water soluble chitosan was given orally for 15 days before conception. In group 3, 0.3% water soluble chitosan was injected intravenously for 15 days, once daily before conception. Gamma counting of newborns were done at days 0, 2 and 7 after their births. Whole body retention of Sr-85 in newborns of control mice at days 0, 2, 7 were 3.1 ±0.3%, 2.9 ±0.3%, 2.8 ±0.3% respectively. In experimental groups, whole body retention of Sr-85 was significantly lower thanthat of control(p<0.01) and no statistical difference was noted between them. In group 1, the values were 2.1 ±0.3%, 1.4 ±0.1%, 1.4 ±0.1%, respectively. In group 3, they were 2.1 ± 0.2%, 1.7 ± 0.2%, 1.6 ± 0.2%, respectively. In conclusion, the water soluble chitosan reduced transplacental contamination of radiostrontium in pregnant mice.

본 연구에서는 마우스에 이미 오염된 방사성스트론튬(Sr-85)을 제거하는데 수용성카이토산이 어느정도 효과가 있는지 알아보고자 하였다. Sr-85를 정맥주사한 경우 주사후 1일째의 체내 잔류량은 72.9 ±5.7%, 5일째는 57.7 ±1.9%, 7일째는 54.2 ±1.4%로 서서히 감소하였으며, Sr-85를 복강내 주사한 경우는 주사후 5일째 54.4 ±1.2%, 15일째 50.6 ±0.8%로 정맥주사에 비해 낮은 잔류량을 보였다(5일째 잔류량의 비교, P<0.05), 0.3% 수용성카이토산을 1회 정맥주사해준 제21군 및 10% 수용성카이토산을 식이중에 섞어 먹인 제5군은 각각의 대조군에 비해 체내 잔류방사능의 차이가 없었으나 (P>0.05), 0.3% 수용성카이토산을 3일간 정맥주사한 제3군과 3% 수용성카이토산을 이틀 간격으로 15일간 복강내 주사한 제6군에서는 각각의 대조군에 비해 낮은 잔류방사능을 보였다. (P<0.01). 결론적으로 수용성카이토산을 연속적으로 정맥투여하거나 복강내 투여하는 경우에는 스트론튬의 골대사촉진 또는 골중의 스트론튬과의 반응등을 통해 그 배출을 촉진시킬 것으로 사료되었다. The aim of the present study was to elucidate the effect of the water soluble chitosans on the removal of contaminated radiostrontium(Sr-85) from the bone of mice. The remaining radioactivities in intravenously injected controls(group 1) were higher than in intraperitoneally injected controls (group 4, P<0.01). The % retention at day 5 were 57.7 ±1.9%, 54.4 ±1.2%, respectively. Single intravenous injection of 0.3% water soluble chitosan and continuous oral ingestion of 10% water soluble chitosan for 15 days were ineffective on the removal of contaminated radiostrontiums. Multiple intravenous or intraperitoneal injections of water soluble chitosan effectively removed contaminated radiostrontiums (P<0.01 vs controls). In conclusion, water soluble chitosan might remove once incorporated radiostrontium from bones of mice. further studies were needed to elucidate the mechanism of the removal.

연구목적 : 본 시험의 목적은 임상시험 시작전에 연구자들을 대상으로 PANSS Workshop을 통하여 PANSS, ESRS에 대한 국내에서의 표준화 작업을 구축하고 새로운 정신병 치료제인 리스페리돈의 효과와 안정성을 재확인하여 리스페리돈 사용에 대한 적정화를 이루는데 있다. 연구방법 : 1996년 4월부터 1996년 9월까지 국내 39개 대학병원 정신과에 입원중인 혹은 증상이 악화되어 입원하는 정신분열병 환자 377명을 대상으로 다시설 개방 연구를 시행하였다. 1주일간의 약물 배설기간을 가진후, 리스페리돈을 8주간 투여하였고, 기준점, 1주, 2주, 4주, 그리고 8주후에 평가되었다. 용량은 제1일에는 리스페리돈 1mg씩 1일 2회, 제2일에는 2mg씩 1일 2회, 제3∼7일에는 3mg씩 1일 2회 투여하였다. 이후 환자의 임상상태에 따라 임의로 증량할 수 있으며, 최대 일일 16mg을 초과하지 않도록 하였다. 추체외로 증상을 조절하기 위한 투약을 허용하였다. 임상증상 및 부작용의 평가는 PANSS(Positive and Negative Syndrome Scale), CGI(Clinical Global Impression) 그리고 ESRS(Extrapyramidal Symptom Rating Scale)을 사용하였다. 연구결과 : 377명중 343명(91%)이 8주간의 연구를 완결하였다. 치료 종결시점인 8주후 PANSS 총점수가 20% 이상 호전된 경우를 약물 반응군으로 정의할때, 약물반응군은 81.3%였다. 리스페리돈에 반응하는 예측인자로는 발병연령, 이전의 입원 횟수, 유병기간이 관련 있었다. 리스페리돈은 1주후부터 PANSS양성, 음성, 및 일반정신병리 점수상에 유의한 호전을 보여 효과가 빨랐다. CGI의 경우도 기준점에 비해 1주후부터 유의한 감소를 나타내었다. ESRS의 경우, 파킨슨 평가점수는 기준점과 비교해 투여 1주, 2주, 4주후 유의하게 증가되었다가 8주후 기준점과 차이가 없었다. Dystonia 평가점수는 1주후만 유의한 증가를 보였으며, dyskinesia 평가점수는 유의한 차이가 없었다. 혈압, 맥박수의 생명징후 및 일반 혈액학 검사, 생화학적 검사, 심전도 검사에서 유의한 변화는 없었다. 결 론 : 이상의 다시설 개방 임상 연구를 통해 리스페리돈은 정신분열병 환자에서 양성증상뿐만 아니라 음성증상 및 전반적인 증상에도 효과적인 것으로 사료된다. 보다 명확한 평가를 위해서는 다른 항정신병약물과의 이중맹검 연구가 필요할 것으로 생각되며, 또한 장기적 치료에 대한 평가도 함께 이루어져야 하겠다. Objective : The purpose of this study was to investigate the efficacy and safety of risperidone in the treatment of Korean schizophrenic patients. Method : This multicenter open study included 377 schizophrenic patients drawn from 39 university hospitals. After a wash-out period of 1 week, the schizophrenic patients were treated with risperidone for 8 weeks and evaluated at 5 points ; at baseline, and 1, 2, 4 and 8 weeks of treatment. The dose was increased from 2mg/day(1mg twice daily) to 6mg/day(3mg twice daily) during the first week and adjusted to a maximum of 16mg/day over the next 7 weeks according to the patient's clinical response. Medication to control extrapyramidal symptoms was permitted. The psychiatric and neurological status of the patients was assessed by PANSS, CGI, and ESRS scales. Results : 343(91%) of 377 patients completed the 8-week trial period. Clinical improvement, as defined by a 20% or more reduction in total PANSS score at end point, was shown by 81.3% of patients. The predictors of response to risperidone were associated older age, shorter duration of illness, fewer previous hospitalization. Risperidone had rapid onset of action ; a significant decrease of the total PANSS and three PANSS factor(positive, negative, general), and CGI was already noticed at the end of first week. For the ESRS, parkinsonism rating scores were significantly increased until week 4 comparing with baseline. Dystonia rating scores were significantly increased until week 1, and dyskinesia rating scores were not significantly changed during the study. Laboratory parameters including vital sign, EKG, hematological, and biochemical values showed no significant changes during the trial. Conclusions : This study suggests that risperidone is generally safe and effective against both the positive and negative symptoms in our group of patients.

대량생산을 위한 김치의 산업화에 있어서 가장 큰 문제점인 유통시의 산패현장과 포장팽대 및 파손을 지연시켜 김치의 저장기간을 연장하고자 이산화탄소 흡수능력을 가진 물질을 가스흡수제로 처리하여 저장중 김치의 품질을 검토하였다. 품질평가를 위한 측정항목은 pH, 산도, 색상, 이산화탄소 함량 및 젖산균수 그리고 총균수를 측정하였다. 수산화칼륨, 수산화칼슘, 수산화나트륨과 같은 알칼리물질과 연화마그네슘, 염화칼슘과 같은 염화합물을 가스흡수제로 사용한 결과, 수산화칼륨과 수산화나트륨처리구가 타처리구에 비해 pH의 감소가 적었으며, 또한 산도의 증가가 다소 낮았다. 수산화칼륨과 수산화나트륨을 각각 0.25%, 0.5%, 0.75% 세단계의 농도로 처리한 결과 pH와 산도에 있어서 수산화칼륨처리구가 수산화나트륨처리구에 비해 높은 pH와 낮은 산도를 나타내었다. 또한 각 처리구의 농도에 따라 큰 차이가 나타나지 않아 간편성과 경제적인 면, 그리고 시각적인 면을 고려해 볼 때 0.25% 수산화칼륨처리구가 탄산가스흡수에 의해 김치의 저장기간을 연장하는데 다소 효과를 보였다. PE bag으로 포장된 수산화칼슘과 PE flim(0.02㎜)으로 포장한 0.25% 수산화칼륨을 가스흡수제로 사용하여 무처리구와 비교하여 저장중 김치의 품질을 검토하였다. 저장중 0.25% 수산화칼륨처리구와 시판용 김치의 가스흡수제인 수산화칼슘처리구를 비교할 때, 수산화칼륨처리구가 무처리구에 비해 pH 및 산도의 차이가 컸으며, 김치의 조직과 국물속에 용해되어 있는 이산화탄소의 함량도 적었다. 그리고 총균수에 있어서 타처리구에 비해 수산화칼륨처리구가 높은 값을 나타내었다. When kimchi was manufactured and circulated, largest question is rancidity phenomenon and packing swelling. This study was conducted to prevent these phenomenon and prolong the shelf-life of kimchi. KOH, NaOH, Ca(OH)_2, MgCl_(2), and CaCl_(2) were used to gas-absorbent. The pH of kimchi used KOH, NaOH was higher than the others. The acidity of kimchi used KOH, NaOH was lower than the others. The concentration of KOH, NaOH was 0.25%, 0.50%, 0.75%. The decrease of pH and increase of acidity that kimchi dealt with KOH were lower than kimchi used NaOH. There in no significant difference in concentration of gas-absorbent. Comparision of kimchi used 0.25% KOH and Ca(OH)_2. Ca(OH)_2 packaged PE bag and 0.25% KOH packaged PE film(0.02㎜) were used to gas-absorbent. On comparision to control, kimchi dealt with 0.25% KOH was higher than kimchi used Ca(OH)_2 at pH and acidity. The CO_(2) contents of kimchi dealt with 0.25% KOH was lowest. The number of total microbe kimchi dealt with 0.25% KOH was highest.

T.S. Eliot 詩의 Imagery 硏究

尹光熙 배화여자대학 1996 培花論叢 Vol.15 No.-

The purpose of this study is to clarify major images which are deploying the theme in The Waste Land and Four Quartets. T.S.Eliot thinks that the state of things in modern society is a situation of death-in-life. That is, Eliot thinks that modern man is alive in terms of flesh but is dead spiritually. And he thinks that the factor of this modern waste land is distortion of sex and failure of true love. In The Waste Land, therefore, Eliot is concerned with rebirth through recovery of that true love. Eliot structures his poem around various religious and mythological stories in which the ideas of rebirth are involved. Among them, Fisher King's story in the Grail legend becomes a basic framework. In the ancient Grail legend, Fisher King suffers from impotence of sex, and owing to his impotence his land becomes barren. Ancient people believed that if this Fisher King's impotence were healed, the barren land would be recovered. But the king's impotence would not be healed before a pure knight appeared and succeeded in his search for the Grail after experiencing many difficulties. In the poem, Eliot presents Tiresias as such a knight who has traveled as a knight in search of the Grail. Consequently, the framework of The Waste Land is based upon Tiresias's quest for rebirth through love. But since Tiresias fails in achieving rebirth in this poem, The Waste Land ends with a formula for purgatorial suffering, through which Tiresias may achieve spiritual knowledge after patience and self-denial. Eliot thus thinks that rebirth of the modern waste land depends upon true love which involves inward conversion. To sum up, The Waste Land's basic theme of "death" and "rebirth" turns around the question of inward conversion and true love. In Four Quartets, the religious implications in the poem are mainly christianity in character. A dominant theme of transcendental moment is expressed through the poem's central imagery of the still point. But it is neither the expression nor the explication of the christian face. It contains various ideas from many different sources - Aristotle, Heraclitus, Bradley, Bergson, Christianity and Buddhism, etc. They are all amalgamated into the poem. It is not the purpose of Four Quartets to expound any of those specific ideas. Rather, it is to evoke religious feeling among reader's mind in a sceptic age. It is not the expression of the personality of Eliot the man. The poem should be read as a coherent 'significant emotion' of Eliot; the reader, then, will be able to find an enriching spiritual experience in reading it. Furthermore, we feel that his poems are unified by one singnificant, consistent, and developing matter; his poetry is a quest for 'Unity' or 'Reality'. In other words, his earlier, middle, and later poems are actually stages of a single endeavor toward the union of man and God. The starting point of this development is the desperate state of the poet in his earlier poems. The middle poems are seen as a movement toward affirmation that shows the possibility of relief toward God. In this process, at last, his later poems achieve the state of 'unity' - which is the union of man and God. His quest for 'unity' is complete. This quest is comparable to the journey from Inferno through Purgatorio to Paradiso. In Divine Comedy, Eliot sees two aspects of reality. One is the perfection of the self and the other is the structural perfection for the poetic beauty. Influenced by Dante, Eliot expresses his idea through such images as "water", "fire", "stair" and "Rose Garden", and each image is connected with the poet's spiritual progress. "Water" represents the element of life, "fire" symbolizes desire and purification, "stair" reflects the progress toward a new reality, and "Rose Garden" symbolizes the state of union of man and God. In The Waste Land, Eliot presents the three revelational words, "give, sympathize, and control", as the minimum requirement for unity with God. The meditative voices of Four Quartets emphasize that time can be redeemed only by the purification of self in the refining fire. Eliot's religious heritages affect his theme on the whole, and grouped together, two poems construct a unified continuum.

W. B. Yeats의 Cuchulain Cycle에 나타난 윤회관 연구

尹光熙 배화여자대학 2001 培花論叢 Vol.20 No.-

W. B. Yeats was interested in the glory and faith of the ancient Ireland, which he thought were embodied in the old Celtic myths and legends. All his life, he tried to incorporate the glory and faith into modern Irish nationalism and culture. He believed in the restoration of the old Irish heroism in the modern Ireland. His concern with the restoration of the old glory and faith was closely related with his vision of cyclical processes that he tried to articulate throughout his life. Yeats employed Cuchulain as hero of his Cuchulain cycle. He regarded modern Irish nationalists such as James Connolly and Padraic H. Pearse, who declared the establishment of the Irish Republic, and led the Easter uprising in 1916, as the reincarnation of Cuchulain. In his Cuchulain cycle, thus, he dealt with the theme of the modern restoration of the glory and faith of the old Ireland. The purpose of this thesis is to examine how Yeats's vision of cyclical processes is symbolically dramatized in his Cuchulain cycle, which consists of the five plays, At the Hawk's Well, The Green Helmet, On Baile's Strand, The Only Jealousy of Emer and The Death of Cuchulain. If we approach the five Cuchulain plays as a cycle beginning with At the Hawk's Well and ending with The Death of Cuchulain, we find that each play can be related to an important phase on the Great Wheel. We can also understand that the cycle is applied to the solar imagery in terms of resurrection as well as to the imagery of the romance of Sun and Moon. Furthermore, the Cuchulain plays are associated with the changing points of the seasons, namely, solstice and equinox. These images are all concerned with Yeats's creation of a ritual of resuscitating a lost faith and glory in modern Ireland. That is, Yeats designed the Cuchulain cycle not only as a drama but as a ritual or restoring the old Irish heroism in modern Ireland.

試用期間의 勤勞契約 法理

윤광희 한국노동법학회 2003 노동법학 Vol.0 No.16

It is probational periods system that employers make laborers be on the job approximately 2-3months gazing on their aptitudes and abilities to work. It has relation to the life-time employment system. And the employers can exercise their rights to rescind consideration certain evaluations before making formal employments. Because the contract of probational periods system reserves rights to rescind, the probational periods are allowed to exercise within 3months. The laborers in probational periods can be under the protection of the Labor Standards Law before expiration. And they can get qualification of formal employees. However the claim rescission relays on employers' judgements, they can reject to enter into formal employments in their own. In this case, Laborers in probational periods are divested qualifications being under the protection of law. The exercising rescission is allowed more extensively, the positions of the laborers are lack of stability. Therefore the rescission should be admitted strictly consideration resonable, rational bases such as attitude, ability and eligibility in working. Also the evaluating eligibility should be impartial and objective. Whether the rescission of formal employment is not based on rational reason or the probational periods are excessively protracted, it will be invalid because of the abuse of rights. The extend or the renewal of the probational periods is prohibited for protection of the employees. And the contract of the probational periods which are indefinite should be annulled. If the rescind formal employment is sentenced for invalid or so, it should be taken for making formal employment at the expiration date of the probational periods.

韓牛改良을 爲한 屠體特性에 關한 硏究

Carcasses from thirty (male : 12, female: 18) Korean Cattle were used to study the yield of meat cuts by the conventional cutting method as well as the American method. The dressing percents and correlation cofficients among meat cuts in a carcass were also investigated. The regression equations for predicting the total carcass lean from meat cuts is of particular importance in studies of carcass evaluation. Physical separation of the entire carcass is laborious and costly. Therefore, a simple indirect method for predicting total carcass lean would be extremely useful. The regression equations of total carcass lean on certain meat cuts were calculated in this study. Dressing percents from male and female carcasses were 49.64%, 48.37% respectively. Comparing the dressing percents of Korean cattle with idealized beef cattle, the percents from Korean cattle were much below those from beef. The percents of round, chuck, and shortloin from Korean cattle were also lower than those of beef cattle. Correlation coeffidient between carcass and lean weight was highly significant. Correlation coefficients among meat cuts were highly associcted with carcass weight. Therefore, the results of this study indicate that using the regression equations is possible for predicting total lean from certain meat cuts.
