This is a study to search for the ethical basis for valid informed consent of organ donors. It is an admirable action that a person give his own body part or organ as a gift to another person. The organ for transplantation can be removed only when the donor consents voluntarily to donation. It is recently proposed as the need for organ transplantation is increased that organs can be harvested although the consent of deceased cannot be obtained. This may raise many moral issues because human beings all have an unalienable right to control their own bodies. The principle of autonomy is usually regarded as an ethical basis for informed consent. However, some people criticize that the principle of autonomy requires a person and his decision to be autonomous (but there are many patients who aren't autonomous due to their confusion or unconscious condition in a clinical situation). or this principle can foster indifference to patients needing help: thus respect for principles of care and beneficence is necessary. When we consider the complexity of making a decision about organ donation. the principle of autonomy should be replaced by the principle of respect for individual autonomy. as expressed by Childress (1990). This principle requires the care givers to respect the client's individual decisions. The elements of informed consent are threshold elements: competence to understand and decide. voluntariness in deciding: information elements: disclosure of material information. recommendation of a plan. understanding of disclosure and recommendation: and consent elements: decision in favor of a plan. authorization of the chosen plan. In cases of living donors. the elements of competence and voluntariness are more important than the others. So only an adult can give a recipient his own body part. but it should be forbidden to harvest from minors or protected adults (i.e. developmentally disabled person However. when organs are removed from a cadaver donor. we ought to respect the donor's decision. So we ought to try to seek donor cards or any documents expressing the donor's opinion about organ transplant. All health care givers ought to disclose donor information about organ transplantation clearly enough for the donor to understand it and to be able to weigh the harms and benefits. We are going to propose 'the subjective standard' as the ethical standard of disclosure. This standard will assure that patients have enough information to be able to decide autonomously from their own position. Care givers have to consider the method of disclosure because donors can be influenced by it positively or negatively, Establishment of the Hospital Committee is recommended. because medical professionals will have a chance to discuss the procedure of decision and the validity of harvesting a organ from a person.

국소배기장치를 설치하려는 경우 환경부 허가를 받더라도 고용노동부 허가를 새로 받아야 한다. 이는 대기환경보전법 뿐만 아니라 산업안전보건법 제48조2에 따른 제조업 유해위험방지계획서를 착공 15일 전까지 제출하도록 되어 있기 때문이다. 현행 환경부 대기환경보전법에서는 국소배기장치의 오염원을 대기 중으로 배출되는 부분만 규제하고 산업현장 내에서의 근로자 안전보건에 관한 내용은 산업안전보건법 등 고용노동부 소관 법률로 관리된다. 환경부의 승인을 받은 것임에도 고용노동부의 불승인 사례가 증가하여 생산지연 및 추가 개선비용에 따른 사업장의 불만이 커지고 있다. 또한, 화재 폭발의 위험성이 큰 국소배기장치의 경우 화재 폭발에 의한 중대산업사고 위험성이 증가하고 있다. 원인은 배풍량, 제어속도, 반송속도, 덕트구경, 화재폭발 위험성 등의 설계가 미흡했기 때문이다. 이는 국소배기장치 승인기준 및 절차는 대동소이 하나 산업안전보건법에서 근로자의 안전보건 및 화재 폭발에 대한 심사항목이 추가되어 있기 때문이다. 본 연구에서는 환경부와 고용노동부에서 이원화 되어 있는 국소배기장치 설치 승인기준을 비교 분석하여 합리적인 제도운영 방안을 모색하고자 한다.

Recently, for successful lactation, many breastfeeding mothers seek various products, including herbal medicine, dietary supplements, and prescribed medicines, to improve milk production. As demand for galactogogues grows, it is highly possible that pharmaceutical galactogogues may be adulterated with illegal products to maximize their efficacy. For continuous control and supervision of illegal products, we developed and validated a simple and sensitive LC-MS/MS method capable of simultaneously determining five galactogogues. Chromatographic separation was conducted using an Agilent Poroshell $120SB-C_{18}$ column with a mobile phase consisting of 20 mM ammonium formate (pH 5.4) and 100 % acetonitrile. The total run time was 13 min per analyte. The proposed method was performed according to the guidelines of the International Conference of Harmonization and it produced reliable results. This method showed high sensitivity and specificity, with a limit of detection (LOD) and limit of quantitation (LOQ) of 0.01-0.82 ng/mL and 0.02-2.45 ng/mL, respectively, for the solid- and liquid-type samples. Specificity was evaluated by analyzing matrix-blank samples spiked with the target compounds at LOQ levels, which provided a good separation of all peaks without interference. Additionally, the repeatability and intermediate precision were typically <15 %, whereas the recovery was 80-120 % of the values obtained using blank samples. Thus, we concluded that this method could be used for the identification and quantification of galactogogues in food or herbal products.

육상 탄성파자료에 나타나는 일관성 잡음인 그라운드롤을 제거하기 위해 특이값 분해 필터링의 적용성을 살펴보았다. 상관성이 높은 반사에너지가 요구되는 특이값의 계산을 위해 먼저 자동이득제어로 감쇠된 진폭을 보상하고 송수신점의 높이보정 및 풍화대 보정을 실시하여 장파장 시간차이를 제거한 후, 나머지 정적보정으로 단파장 시간차이를 완화시켜 반사면의 수평적인 연속성을 높였다. 특이값 분해 필터링에 적합한 입력인자(최대 주성분)는 공통중간점 자료에 수직시간차 역보정을 수행하여 얻은 공통발파점 자료에 대한 연속 테스트로 결정하였다. 그라운드롤의 시간에 따른 분산이 뚜렷한 현장자료에서 특이값 분해 필터링은 일반적인 기법인 f-k 필터링에 비해 반사신호의 왜곡없이 그라운드롤의 영향을 최소화하면서 주요 반사면들의 연속성을 향상시키는데, 이것은 진폭 빛띠에서 반사파의 낮은 진동수 성분들이 필터링 후에도 보존되었다는 점과 잘 상관되었다. 특히 특이값 분해 필터링을 거친 후 S/N 비를 높일 수 있는 자료처리(송곳곱풀기, 시간변화 빛띠흰색화) 과정을 함께 수행하여 겹쌓기한 결과 저류층을 포함한 주요 반사면들의 향상된 연속성과 분해능을 확인할 수 있었다.

In coastal areas that are affected by continuous, seasonal or occasional pollution sources, bivalves accumulate biological contaminants such as pathogenic bacteria. We investigated the effect of natural seawater relaying and electrolyzed seawater depuration on the bacteriological quality of artificially contaminated oysters Crassostrea gigas and short-necked clams Ruditapes philippinarum to suggest an alternative method of shellfish sanitation control.When artificially contaminated oysters and short-necked clams (fecal coliform level 1,700 MPN/100 g) were relayed into a sea area of safe bacteriological water quality, the fecal coliform level dropped to below 110 MPN/100 g after 1 day. The bacteriological quality of oysters and short-necked clams that are contaminated at a fecal coliform level of 1,700 MPN/100 g could be improved, and become appropriate for raw consumption by a single day relay under proper environmental conditions. When artificially contaminated oysters (fecal coliform level 330 MPN/100 g) were depurated with electrolyzed seawater, 94% of fecal coliform was eliminated after 12 h and fecal coliform was undetectable after 24 h. After 24 h depuration with electrolyzed seawater, the fecal coliform level of short-necked clams with initial fecal coliform of 2,400 MPN/100 g was below 20 MPN/100 g. However, the fecal coliform level of short-necked clams with initial fecal coliform of 17,000 MPN/100 g was relatively high, at 790 MPN/100 g, even after 24 h of depuration with electrolyzed seawater, because of the repeated cycle of excretion and accumulation of fecal coliform in shellfish tissue under the closed depuration environment. Such natural seawater relaying and electrolyzed seawater depuration can be restrictively applied to improve or secure the bacteriological quality of oysters and short-necked clams in accordance with safety levels for bivalves for raw consumption.

Since the 20th century, it was often announced that a painting was dead, but it is still alive. Even in the epoch of recently increasing virtuality, painting is still appealing, consistently pursed by many with a thirst. Thus, it is said that the mission of a picture is to maintain its reality without being trapped in virtuality. In the history of Western painting spanning over several hundreds of years the myriad of techniques and styles have emerged, going though a huge variety of changes: namely, its not possible any longer to find the new ways of expression in painting. Hence, painters today feel that it becomes more gradually difficult for them to execute something. In the midst of swiftly changing, diversely evolving trends of contemporary art, the painters incessantly pose a question why they go on working on painting, and seek to find its answer. Why the painters still try to say something about painting? Is that because they consider it the quintessence of fine arts or think that it is in no way possible or meaningful to comment on fine arts without relying on painting? If then, is there any avenue of escape for the painting? The question of the 'crisis of painting' is still raised, when reviewing the rapidly changing conditions of inventing artworks. That is also why the recent works failed to offer a conceptually unified, universally shared perspective of painting. Moreover, painting is left to shrink comparatively with the pervasive existence of videos and installations briskly employing digital images and technologies in their creations. Whats more problematic is the fact that there is a growing sense of crisis not only in the sphere of painting hut also in the entire realm of art. As the organizers and curators of big-scale exhibitions and art projects tend to exploit their space spectacularly, focusing primarily on their abilities to control the space, there is a pervasive notion amongst them that painting is a medium that is not properly to suit such purposes and requests. Today, the death of painting is, in fact, the death of modernist painting, which assumed a central role in the history of art for a considerable amount of time, rather than the death of painting itself. Employing a new paradigm of invention, a picture is now entering a new domain which is perhaps unknown to us. Moving beyond the stereotypical concepts of painting, physical property and flatness, pictures today reveal the introduction of time and space and the penetration of new media such as installation, photography, video and the Internet. Despite such trends, the dexterity and tactile capability of painters is still to be considered significant in the future. The renewal of painting is made in an entirely unexpected manner and place.

The purpose of this study is to study how college students cope with their stress and how the level of their self-differentiation affects degrees of stress and stress-coping strategies. The questionnaires were handed to 497 college students at Y university in Gyeongbuk Province and the data were analyzed in terms of Cronbach's ${\alpha}$-coefficient, frequency and percentage, t-test, and regression analysis by using the SPSS statistical package. The results of this study were as follows: 1. For stress level, degree of self-differentiation and stress coping strategies of the college students, the average scores were 3.56, 2.53 and 3.49, respectively in 5-point Likert Scale, indicating that the students possess the above-average score for the degree of self-differentiation and stress-coping strategies and the below-average score for stress levels. 2. From examination of difference verification of stress levels based on the degree of self-differentiation and effect of degree of self-differentiation on stress levels, it was found that the higher is the degree of self-differentiation the lower is the stress level. 3. From examination of difference verification of stress-coping strategies according to the degree of self-differentiation and effect of degree of self-differentiation levels on stress coping strategies, we found that the students of higher degree of self-differentiation exercise the more active stress coping strategies. These results show that the degree of students' self-differentiation is a significant variable that influences their stress levels and stress control methods. It is thought that students' self-differentiation functions to minimize their stress and to actively cope with their stressful situation and that a high degree of self-differentiation is a significant mediator variable that is beneficial to students' mental health. It follows from the above observations that while college students in this study seem to possess good degrees of self-differentiation and stress coping capabilities and low stress levels they need to seek for the ways to improve their degree of self-differentiation by seeing into themselves and relationships with others around them. Parents, schools and consultation agencies are required to take an active hand to educate and encourage them to cope with their stress positively.
