This study was carried out to investigate the generation and discharge characteristics of non-point pollutants from farmlands in Nak-dong river basin. Annual unit generation load of nitrogen and phosphorus by fertilization in the test paddy field was almost similar to those calculated by the fertilization standards of district agricultural technology center, but it was extremely higher in case of the test dry field. By comparing annual total generation load of nutrients from fertilization to the data of fertilizer marketing, the accurate forecasting of generation load of pollutants was achieved by marketing data. The annual total discharge ratio of nutrients through infiltration and overflow from the farmland of the test paddy field were 9.5% and 1.1%, respectively, and those in the test dry field were 22.0% and 0.1%, respectively. The monthly discharge load of nutrients were shown the highest proportioned to the discharge load from lands, but it showed higher in phosphorus, which was caused by the intermittent discharge of phosphorus accumulated in drainage.

깻잎을 이용한 건강 식품을 개발하고자 먼저 깻잎의 주산지인 금산에서 5월 온실재배한 깻잎과 8월 노지재배한 깻잎들의 품질특성과 향기성분을 조사하였다. 시료깻잎 모두 4.0%의 조단백질과 0.8%의 조지방을 함유하고 있었고, 플라보노이드의 함량은 온실재배 깻잎 25.2%, 노지재배 깻잎 26.5%로 시료깻잎간에 큰 차이는 나타나지 않았으며 조사포닌 함량도 2,7%와 2,8%로 비슷하였다. 시료깻잎의 효소 활성은 오직 알칼리성 단백질 분해효소 활성만이 8월 노지재배 깻잎에서만 물 추출물 7.1 unit, 에탄올 추출불 11.8 unit을 보였고 기타 효소 활성은 없었다. 8월 노지재배 깻잎의 조직감 특성으로 먼저 견고성과 탄력성 등은 잎의 상층부와 중층부 보다 잎받침을 포함하는 하층부에서 높았고 응집성은 하층부가 약간 약하였으며 5월 온실재배 깻잎은 씹힘성이 다서 낮았을 뿐 노지재배 깻잎과 비슷하였다. 5월 온실재배와 8월 노지재배 깻잎에는 1-octen-3-ol, linalool, β-caryorhyllene, α-caryophyllene, α-famesene, perilla ketone, nerolidol, eugenol. α-cadinol 등 14종∼15종의 향기성분을 함유하고 있었고 주요한 향기성분은 perilla ketone 이었다. Quality and flavor compounds of perilla leaves cultivated in greenhouse(May) and field (August) in Geumsan province were investigated and compared. All perilla leaves contained 4.0% crude protein and 0.8% crude lipid. C겨de flavonoid contents of perilla leaves cultivated in greenhouse and field showed 25.2% and 26.5%, respectively and each crude saponin content was cultivated in field. Hardness and chewness of bottom parts of field-perilla leaves were higher than those of top and middle part, whereas the cohesiveness of top parts and middle parts of perilla leaves were higher than that of bottom part. Furthermore, texture properties of greenhouse-perilla leaves were similar with those of field-perilla leaves except chewness. Nine kind of flavor compounds such as 1-octen-3-ol, linalool, β-caryophyllene, α-caryophylene, α-franesene, perilla ketone, nerolidol, eugennl, α-cadinol were identified in greenhouse-perilla and field-perilla leaves, showing that main flavor compound was perilla ketone.

이 연구의 목적은 경도 정신지체아동의 학습된 무력감을 감소시키기 위하여 체계적인 귀인훈련를 적용함으로써 학업성취능력과 학습태도 개선에 미치는 영향을 밝히는데 있다. 연구대상은 개인용 지능검사 결과 IQ 60-75사이이고 초등학교 특수학급에서 시간제 특수교육을 받고 있는 이동 3 명으로서 신체 및 언어장애와 같은 심한 장애가 없는 아동이다. 연구결과, 귀인훈련이 오랜 학교학습상황에서 겪게 된 학습의 실패상황에서 실패원인을 「능력」에 귀인하는 아동을 「노력」 에 귀인하도록 힘으로써 아동의 「학습된 무력감」 를 감소시키는데 효과적임이 밝려졌다. 즉,뺄셈학습과제의 수행속도가 귀인훈련 후 빨라졌으며 과제에 대한 흥미도 많이 증가하였다. 또한 귀인훈련이 경도 정신지체 아동의 학습태도를 개선하였다. 귀인훈련 후 아동의 실패과제에 대한 지속시간이 많이 늘어났으며, 아울러 실패과제에 대한 불안행동이 많이 감소하였고, 주의집중이 향상되며 학습태도가 바람직히게 변화된 것으로 나타났다. 이 결과는 귀인훈련을 통해 경도 정신지체아동의 학업성취도와 학습태도에 긍정적인 변화를 가져올 수 있음이 확인되었다. The purpose of the present study is to investigate how systematic atributional training affects leaming achievements and leaming attitudes for the children with mild mental retardation through decreasing their feelings of learned helplessness. For the study, three children with mental retardation, whose 1Qs range from 60 to 75, were selected from those who were enrolled at special classes of elementary schools. They do not have physical handicapped and language problems. The procedure applied to this study focused on the changes the reason for the learning failure from "their ability" to "their lack of effort".

妻弟와 兄夫間의 婚姻可否論

鄭光鉉 서울대학교 1966 서울대학교 論文集 Vol.12 No.-

Under the old Korea civil law, marriage between a man and his wife's sister (or between a woman and her deceased or divorced sister's husband) was deemed valid. Yet under the present Civil Code, interpretation of the law have brought about two opposing views on the matter: the one deems the marriage between a man and his wife's sister as valid and the other as invalid. The writer and most scholars hold that marriage between a man and his wife's sister as valid under the present law, while the Korean Supreme Court and some others oppose this view. This article, to begin with, states about the theoretical grounds of the two opposing interpretation of law and attempts to show that the arguments holding the marriage as invalid have no ground in a reasonable interpretation of the present Korean Civil Law, arguing that the interpretation of the present law as upholding the marrige between a man and his wife's sister is most resaonable.

Abstract - Olanzapine is an atypical antipsychotic drug that is widely used for the treatment of schizophrenia and acute bipolar disorder. It had been reported that olanzapine was shown enterohepatic recirculation in rat and human. But pharmacokinetic model for enterohepatic recirculation of olanzapine had not been developed yet. In this study, we developed pharmacokinetic model for enterohepatic recirculation of olanzapine. 30mg/kg of olanzapine was administered to rats (n=7) by oral and plasma concentration of olanzapine was determined by HPLC-MS/MS(API2000). Noncompartmental analysis was done by WinNonlin and pharamcokinetic model was developed by NONMEM ver 7.2. Enterohepatic recirculation model was developed with two compartment including gall bladder compartment with mtime option and evaluation was done by visual predictive check(VPC) and bootstrap. As a result of VPC and bootstrap, our model was robust and parameter values were reliable. In conclusion, pharmacokinetic model for enterohepatic recirculation of olanzapine was successfully developed and evaluated. The model was appropriate to predict the plasma concentration of olanzapine in rat and may be useful to develop human model in further study.
