Purpose - In general, researchers try to abide by the code of research ethics, but many of them are not fully aware of plagiarism, unintentionally committing the research misconduct when they write a research paper. This research aims to introduce researchers a clear and easy guideline at a conference, which helps researchers avoid accidental plagiarism by addressing the issue. This research is expected to contribute building a climate and encouraging creative research among scholars. Research design, data, methodology & Results - Plagiarism is considered a sort of research misconduct along with fabrication and falsification. It is defined as an improper usage of another author's ideas, language, process, or results without giving appropriate credit. Plagiarism has nothing to do with examining the truth or accessing value of research data, process, or results. Plagiarism is determined based on whether a research corresponds to widely-used research ethics, containing proper citations. Within academia, plagiarism goes beyond the legal boundary, encompassing any kind of intentional wrongful appropriation of a research, which was created by another researchers. In summary, the definition of plagiarism is to steal other people's creative idea, research model, hypotheses, methods, definition, variables, images, tables and graphs, and use them without reasonable attribution to their true sources. There are various types of plagiarism. Some people assort plagiarism into idea plagiarism, text plagiarism, mosaic plagiarism, and idea distortion. Others view that plagiarism includes uncredited usage of another person's work without appropriate citations, self-plagiarism (using a part of a researcher's own previous research without proper citations), duplicate publication (publishing a researcher's own previous work with a different title), unethical citation (using quoted parts of another person's research without proper citations as if the parts are being cited by the current author). When an author wants to cite a part that was previously drawn from another source the author is supposed to reveal that the part is re-cited. If it is hard to state all the sources the author is allowed to mention the original source only. Today, various disciplines are developing their own measures to address these plagiarism issues, especially duplicate publications, by requiring researchers to clearly reveal true sources when they refer to any other research. Conclusions - Research misconducts including plagiarism have broad and unclear boundaries which allow ambiguous definitions and diverse interpretations. It seems difficult for researchers to have clear understandings of ways to avoid plagiarism and how to cite other's works properly. However, if guidelines are developed to detect and avoid plagiarism considering characteristics of each discipline (For example, social science and natural sciences might be able to have different standards on plagiarism.) and shared among researchers they will likely have a consensus and understanding regarding the issue. Particularly, since duplicate publications has frequently appeared more than plagiarism, academic institutions will need to provide pre-warning and screening in evaluation processes in order to reduce mistakes of researchers and to prevent duplicate publications. What is critical for researchers is to clearly reveal the true sources based on the common citation rules and to only borrow necessary amounts of others' research.

녹즙분말과 콜레스테롤 첨가식이로 8주간 사육한 흰쥐의 혈중 지질, 호모시스테인 및 엽산수준에 미치는 효과를 관찰한 결과는 다음과 같다. 흰쥐의 혈중 총 콜레스테롤 농도는 녹즙이나 콜레스테롤 보충에 의해 유의한 영향을 받지 않았으나 중성지질 농도는 녹즙군에서 낮았다(p<0.001). HDL-콜레스테롤과 LDL-콜레스테롤의 경우, 식이 콜레스테롤의 영향을 받아, HDL-콜레스테롤은 콜레스테롤군보다 무콜레스테롤군에서 높았으며 (p<0.001), LDL-콜레스테롤은 콜레스테롤군에서 높았다(p<0.05). HDL-콜레스테롤 수준은 녹즙군에서 높았으며 (p<0.05), LDL-콜레스테롤 농도는 콜레스테롤과 케일의 상호효과가 나타나 무콜레스테롤군에서 만 녹즙에 의한 감소효과를 보였다 HDL/LDL비율은 콜레스테롤 보충군에서 낮았으며 (p<0.05), 녹즙보충군에서 높았으나 통계적으로 유의한 결과를 나타내지 못하였다. 혈청 엽산, 비타민 $B_{12}$ 및 혈장 호모시스테인 농도는 녹즙분말이나 콜레스테롤 보충에 의해 영향을 받지 않았다. 혈중 엽산과 비타민 $B_{12}$ 농도사이에는 유의한 양의 상관성 (r=0.5632, p<0.001)이 관찰되었으나, 혈중 호모시스테인 농도는 혈중 엽산, 비타민 $B_{12}$ 및 콜레스테롤 농도 사이에는 모두 유의한 상관성이 관찰되지 않았다. 본 연구결과를 종합하여 보면, 엽산이 충분히 공급되는 경우, 녹즙보충시 나타나게 되는 심혈관계질환 예방효과는, HDL 농도의 증가 및 중성지방 농도의 감소에 의한 것이며, 녹즙내 엽산보충에 의한 호모시스테인 농도 변화와는 관련이 적은 것으로 사료된다.

The subjects for nursing investment and output contents were eighteen nursing directors in eleven Oriental University Medical Center and two hundred thirty-nine nurses with three years and over experience in Oriental medical center. The subjects for Oriental nursing organization, human affair management, and control function were nineteen Oriental medical center in Oriental University Medical Center, Korea. Data were collected from November, 2002 to February, 2003 with questionnaire. Data analysis was done by SPSS PC+ 12 program. Frequency, percentage, and minimum/maximum values were used for investment contents, and frequency and percentage were used for conversion process and output contents. 1. The input factors of oriental nursing management system The objective's western hospital career was over five years of one hundred and seventy-five(73.2%) persons. Nursing in-service education was performed in fourteen hospitals(77.8%). Two hundreds(83.7%) were pro to oriental nurse system. Only four hospitals(22.2%) had independent budget in nursing division. Nursing staff allocation to the bed was from 2.8:1 to 9.06:1 respectively, with a big gap of the rate following the hospitals. 2. The conversion factors of oriental nursing system 1) Oriental nursing system Oriental hospital nursing system was organized independently in ten hospitals among eighteen hospitals. The recruitment of nurses which was a vital role of the nursing division of the hospital was mostly(79%) opened. The education to develope nursing personnels was through in-service one in 97.4%. Education for oriental nursing and management was performed in 42.1%(eight hospitals) and that for reserves was done in 36.8%(seven hospitals). Administration for nursing education by nursing division was 68.5%(thirteen hospitals). The post education evaluation was performed by report submission in 36.8%(seven hospitals), by written examination in 26.3%, by questionnaires in 21.1%, and by lecture presentation in 15.8% subsequently. The directorial meeting for the nursing directors was attended by 84.2%(sixteen hospitals), and the meeting type was the medical executive and support division executive meeting in 55.6%(ten hospitals) and the personnel management in 39.6%(seven hospitals). 2) The actual conditions of oriental nursing personnel management The reason of working in oriental hospital was by voluntary in 67.1%(a hundred and sixty persons), by nursing department order in 28.0%(sixty-seven persons), and by others in 5.0%(twelve persons) respectively.

General interest in the out-of-court dispute resolution system are mounting in Korea, and the spread of ADR(alternative dispute resolution) is the worldwide trend. In addition, it was confirmed that the resolution of disputes by ADR such as the decision based on arbitration made by the Prime Ministerial Administrative Decision Committee is no longer in exclusive possession of the civil case. The activation of ADR could lead to the smooth agreement between parties by getting away from the once-for-all mode of decision such as the dismissal of the application or the cancellation of disposal and the like in relation to administrative cases for the years. In consequence, it is anticipated that the administrative litigation that applicants have filed by not responding to the administrative decision would greatly reduce in the future. But, it would be urgent to provide for the legal ground of the ADR system through the revision of related laws to take root in our society because ADR has no legal binding power relating to the administrative case due to the absence of its legal grounds. The fundamental reason for having hesitated to introduce ADR in relation to the administrative case for the years is the protective interest of the third party as well as the public interest that would follow in case the agreement on the dispute resolution between parties brings the dispute to a termination in the domain of the public law. The disputes related to the contract based on the public law and the like that take on a judicial character as the administrative act have been settled within the province of ADR by applying the current laws such as the Civil Arbitration Law, Mediation Law, but their application to the administrative act of the administrative agency that takes on a character of the public law has been hesitated. But as discussed earlier, there are laws and regulations that has the obscure distinction between public and private laws. But there is no significant advantage in relation to the distinction between public and private laws. To supplement and cure these defects it is necessary to include the institutional arrangement for protection of the rights and benefits of the third party, for example the provision of the imposition of the binding power on the result of ADR between parties, in enacting its related law. It can be said that the right reorganization of the out-of-court dispute resolution system in relation to the administrative case corresponds with the ideology of public administration for cooperaton in the Administrative Law. It is high time to discuss within what realm the out-of-court dispute resolution system, alternative dispute resolution system, can be accepted and what binding power is imposed on its result, not whether it is entirely introduced into the administrative case. It is thought that the current Civil Mediation Law or Arbitration Law provides the possibility of applying arbitration or mediation only to the civil case, thereby opening the possibility of arbitration in the field of the intellectual property right law. For instance, the act of the state is not required in establishing the rights related to the secret of business or copyrights. Nevertheless, the disputes arising from or in connection with the intellectual property rights law is seen as the administrative case, and they are excluded from the object of arbitration or mediation, which is thought to be improper. This is not an argument for unconditionally importing ADR into the resolution of administrative cases. Most of the Korean people are aware that the administrative litigation system is of paramount importance as the legal relief for administrative cases. Seeing that there is an independent administrative decision system based on the Administrative Decision Law other than administrative litigation in relation to administrative cases, the first and foremost task is the necessity for the shift in thinking of people, followed by consideration of the plan for relief of the rights through the improvement of the administrative decision system. Then, it is necessary to formulate the plan for the formal introduction and activation of ADR. In this process, energetic efforts should be devoted to introducing diverse forms of ADR procedures such as settlement conference, case evaluation, mini-trial, summary jury trial, early neutral evaluation adopted in the US as the method of dispute resolution other than compromise, conciliation, arbitration and mediation

This study investigated stress and the extent of climacteric symptoms in mid-life men, and examined their relationship in order to better understand the stress and climacteric symptom experiences of mid-life men, and thereby attempted to offer basic materials for the development of a health improvement program that may help increase the quality of life of mid-life men. Three hundred mid-life men whose ages were between 40 and 59 and resided in the Seoul area were subjects of this study. The data were analyzed with the SAS PC program using descriptive statistics to analyze subjects' general characteristics and variables of stress and the extent of climacteric symptoms of the subjects. The relationship between stress and climacteric symptoms were examined by the Pearson Correlation Coefficient, and stress and the extent of climacteric symptoms in relation to the general characteristics were analyzed by T-test and ANOVA. The study conclusions are as follows: 1. Subjects general characteristics The average, age of the subjects was 46 and 47.0% of them reported ages between 40 and 45. Of the subjects, 98% were married. In marriage satisfaction, those who were generally satisfied with their married life comprised 62.0% of the subjects. In terms of level of education, 95.7% were educated above the high school level. In occupational background, 59.7% had occupations related to technologies. As for religion, 42.7% had no religion. In number of children, 67.3% had 2 children. In residential status, 79,3% were living in their own homes. In terms of living arrangements, 87.7% of the subjects were living in the form of nuclear families. 2. Stress and the extent of climacteric symptoms The level of stress was scored as $2.94{\pm}0.74$, and considering that the overall examination score is $27.16{\pm}1.32$, the subjects' stress level was not viewed as particularly high. The average score of the extent of climacteric symptoms was $35.37{\pm}0.27$. The extent of sub-domains of climacteric symptoms included skeleton symptoms ($39.37{\pm}2.81$), joint pain ($39.16{\pm}3.66$), vasomotor symptoms ($35.39{\pm}3.01$), other symptoms ($36.99{\pm}3.02$), psychological symptoms ($34.68{\pm}3.01$), urogenic symptoms ($35.03{\pm}3.27$), and cardiovascular symptoms ($33.70{\pm}2.78$). 3. General characteristics in relation to the stress level The subjects' general characteristics that were significantly related to the level of stress were marriage status (F=4.38, p=.001), marriage satisfaction (F=4.56, p=.001), educational background (F=2.68, p=.012), and age (F=2.48, p=.033). 4. General characteristics in relation to the level of climacteric symptoms The subjects' general characteristics that were significantly related to the level of climacteric symptoms were educational background (F=3.26, p=.007), age (F=2.58, p=.027), marriage status (F=2.62, p=.025), and marriage satisfaction (F=2.78. p=.032). 5. The correlation between stress and climacteric symptoms The subjects' level of stress and climacteric symptoms were significantly related to each other (r=0.578, p=0.000). The subjects' level of stress was correlated with sub-domains of the climacteric symptoms including psychological symptoms (r=0.579, p=0.000), joint pain (r=0.479, p=0.000), skeleton symptoms (r=0.477, p=0.000), other symptoms (r=0.467, p=0.000), vasomotor symptoms (r=0.4615, p=0.000), cardiovascular symptoms (r=0.458, p=0.000), urogenic symptoms (r=0.401. p=0.000). In summary, the climacteric symptoms suffered by mid-life men are positively correlated with their level of stress. In addition, the climacteric symptoms were affected by the level of stress.

Every country in the world has been trying to expand the basic health right for the peoples as W.H.O has established the goal 'health for AU' by the year of 2000. Related to this goal, our government authority has establish the policy 'the insurance of health for all' into effect from July 198\). Recently hospitalshave been making a ceaseless effort for the plan for the rationalization of its management the academic World is making it a subject of discussion by doing the secure of manpower at a resonable level and the increase of productivity by the manpower. As a result of the efforts the study was established to secure the numbers of nursing manpower at a resonable level and use the unskilled persons at the utilizing field and seek the possible area of their activity for more efficient service through the investigation of ablity of simple nursing activities of regiestered nurses and nurse aides for rational function according to the educational levels and talents. The method of study was established by the registered nurses and nurse and nurse aides(R.N 229, N.A 226) who are working in 15 hospitals with over 200 beds. This surrey was conducted from Mar 29, 1989 to April 8, 1989. The method to test the degree of importance, difficulties, and the abillity of performance of a simple nursing activities was classified into 35 activities on the basis of references on this field. The degree of importance was composed from point l(Not so important) to 5(Very important). the degree of difficulties. was composed as follows; very easy - Point 1 very difficult and complicated - Point 5. and the ability of performance was composed from point 1 to 5. The materials gathered through the survey were analyzed with frequency, mean standard deviation, percentage. t-test, Anova, pearson's coefficient of correlation, stepwise multiple regression. factor analysis, discriminant analysis. The obtained results are summarized as follows: 1. The recognition values of the simple nursing activities of each group of registered nurse and nurse aides show; The degree of importance; 4.04 and 4.26 The degree of difficulties; 2.72 and 2.94 The ability of performance; 2.07 and 2.38 The brief summary shows there are little differences between who two groups the simple nursing activities turned out to be easy and simple work. 2. Regardless of the degree of importance, and difficulties, the ability of performance the important in fluencing of the degree of the simple nursing activities between the registered nurses and nurse aides was the order of educational level, hospital career, working career in wards and ages of the registered nurses and ages and hospital creer of nurse aides. The result was that the simple nursing activities could easily be familiar through the training of their working environment and period of experience. 3. Among the 35 simple nursing activities the items capable of resonable entrusting to the nurse aides are 5 that is helping bed-bathing, 8itz Bath, using bed pan, care while delivering patient, accompaying patient when visitor's check. There wasn't and differences between RN and nurse aides in performing the above 5 items. In anywhere. so we can say obviosuly that this nursing activities should be performed under the nursing system of which chief of nurse are supposed to supervise nurse aides as a possible function to be entrusted. In view of the above mentioned results, therefore, this partial functional job of the simple nursing activities can able be entrusted to the nurse aides through the regular training course. In case of these functional activities could be entrusted under, the responsibility of registered nurse, we can able suggest to for that there are the following advantages: 1.. In the nursing activities-affairs, the qualified guarantee of the nursing services can be kept and increased or promotoed with accommodation of the required nursing service and roles being expanded presently. 2. In the productivity of the hospital manpower, therefore, we have comt to view and consider in favourly that when an automational administration times would be come in the near future time to hospital affairs as a reality, to utilize the existing nures aides is better rather than investing so as to develop the other source manpowers or seek its for the efficient business management in the operational strategy or its policy.

This study has been done in order to analyze the relationship between climacteric symptoms and the stress of life events. For the purpose of this study. objectives set up were as followings. : 1. Climacteric symptoms complained by middle aged women are studied. 2. The stress of life events experienced by middle aged women is studied. 3. The relationship between climacteric symptoms and the stress of life events is studied. 4. The relationship between climacteric symptoms and general characteristics is studied. and the relationship between the stress of life events and general characteristics is also studied. The sample size of this study was 462 cases. The subjects were middle-aged women. who were from 40 to 60 years old and resided in Seoul. Data were collected by using questionnaires which consisted of 122 questions from Jan. 1 to Feb. 7 in 1992. The questionnaires include questions about general characteristics. climacteric symptoms and life events. The measurement scales for this study were adopted from the climacteric symptoms scale developed by Chi. Sung-Ai and the measurement scale of stress related to life events devised by Lee. Pyoung Sook. The analysis of data collected was done by using SPSS-pc package. Firstly. general characteristics were analyzed by using descriptive statistical methods. Secondly. climacteric symptoms were analyzed by using descriptive statistical methods. the analysis of variance and correlation analysis. Thirdly. the stress of life events was studied by using descriptive statistical methods. the analysis of variance. and tests of independence. The results of this study are as followings. 1. General characteristics of the respondents are as followings: The average age is 49. 13. and the age group from 46 to 50 has $30.5\%$ in the respondents. Christianity is the major religion $(42.6\%)$. and the respondents with a high school diploma are $(43.1\%)$ of the respondents. $60\%$ of all respondents are housewives. and $90.5\%$ are married. The average number of children is 2.71. and the average number of family is 4.24 Monthly income of $39.1\%$ of the respondents is from l,010,000 Won to 2,000,000 Won. The premenopausal group is $4.9\%$. and $45.5\%$ of all respondents are satisfied with marrital life. $43.3\%$ of all feel happy. and $13.9\%$ feel economic frustration. $27.9\%$ of respondents are satisfied with sexual life. and $45\%$ of all report that the amount of recreational activities are more needed. 2. The average score of climacteric symptoms is 1. 8461 (The maximum score is 5.0). The symptoms complained frequently are nervousness. muscle-ache. fatigue. headache and knee-ache. Climacteric symptoms are significantly different in menopausal states. age groups. the number of children, marrital satisfaction. the feeling of life. self-reported health states and sexual satisfaction. 3. The life events occurred frequently were 'discord with husband', 'children's important exams', 'separation from husband related to works' and 'vacation'. When life events are analyzed by factors. the most frequently mentioned factor is 'marrital life'. The stress of life events is significantly different in a few general characteristics (age. the number of children, the number of family, monthly income, menopausal status, the feeling of life. self-reported health states, economic satisfaction). 4. The score of climacteric symptoms complained is significantly different according to the stress of life events (p<0.051, Especially, the difference is the widest in psychological symptoms according to the factor of 'couple. marrital life' among stressful life events. In Summary, climacteric symptoms complained by middle-aged women are related to the amount of the stress of life events. Whether life events are positive of negative is not important. Yet. climacteric symptoms and stressful life events are deeply related to general characteristics. so we can not insist strongly that one be directly related to the other.

외국인 투자자가 한국 시장에 투자를 하는 경우 외국인 투자자는 투자자산에 내재된 환위험과 함께 수익을 환산하는 과정에서의 환위험에 노출된다. 외국인 투자자의 이러한 상황은 투자자산에 내재된 환위험만을 고려하면 되는 국내 투자자와는 구분되는 상황이다. 이러한 차이는 외국인 투자자가 환위험에 대해 국내 투자자와는 다르게 반응하는 원인이 될 수 있다. 환위험에 관한 국내의 기존 연구는 한국 기업들이 환위험에 노출되어 있고 이에 대한 관리가 필요하다는 점을 잘 보여주었다. 또한 동일한 시장이라 하더라도 시장 참여자의 특성에 따라 시장이 분할 될 수 있다는 증거들이 보고되었다. 이러한 기존 연구 결과는 환위험이 시장을 분할하는 요인이 될 수 있음을 지지하는 것이다. 이 연구는 한국유가증권시장에서 외국인 투자자들의 환위험에 대한 반응을 거래량 자료와 주문량 자료를 이용하여 분석하였다. 분석 결과 외국인 투자자는 환위험을 나타내는 공분산이 음수인 경우 매도거래를 증가시킨다. 이는 환율이 상승하면서 주식수익률이 하락하는 환위험을 적극적으로 관리하기 위한 거래의 결과로 해석할 수 있다. 주문자료에 대한 분석 결과도 이러한 해석을 뒷받침한다. 한편, 외국인 투자자는 공분산이 음수인 경우 매입거래도 증가시키는 것으로 분석되었는데 이는 환율이 하락하면서 주식수익률이 상승하고 투자수익의 환산이익도 함께 증가하는 관계를 적극적으로 활용하기 위한 거래의 결과로 해석할 수 있다. 그러나 외국인 투자자의 매입주문비율 분석 결과는 거래자료 분석 결과와는 달리 유의적인 결과가 나타나지 않았다. 이 연구의 분석 결과는 외국인 투자자는 국내 자산에 내재된 환위험에 대해서 국내 투자자와는 다른 반응을 보인다는 가설을 지지한다. 외국인 투자자는 환율이 상승(하락)하는 경우 기업가치가 상승(하락)하는 방향의 환위험에서는 국내 투자자와 차별적인 반응을 보이지 않는다. 그러나 환율이 상승(하락)하면 기업 가치가 하락(상승)하는 방향의 환위험에서는 국내투자에 비해 거래를 증가시키는 차별적인 특성을 보인다. 이러한 결과는 한국유가증권시장에서 외국인투자자는 환위험에 대하여 국내 투자자와는 다른 평가를 하고 있으며 이러한 차이는 투자자산의 평가에 반영되고 있음을 나타낸다.

본 논문은 ICRP103 환경방호를 대비하여 국내에서 개발된 야생동식물 선량평가 코드 K-BIOTA의 기술적 배경 및 적용 사례를 기술한다. K-BIOTA는 스크리닝(screening) 선량평가(Level 1&2)와 부지 특성적 상세평가(Level 3)의 3단계의 단계적 평가방법을 적용한다. 스크리닝 단계평가는 상세평가의 필요성 여부를 판단하기 위한 예비적 평가 단계로 개별적인 생물종보다는 동식물을 그룹별로 구분하여 평가한다. Level 1 평가는 스크리닝 목적의 참조준위로부터 유도된 최대환경매체농도 값과 실제 환경매체농도 값의 비교로부터 위험도 지표(risk quotient)를 계산한다. Level 1 평가 결과 위험도 지표가 1보다 작으면 생태계의 건전성이 유지된다는 결론과 함께 평가를 종료하고, 1 보다 크면 동식물 그룹별로 평균적인 전이계수나 평형분배계수 값을 적용하여 조금 더 실제적인 Level 2 평가를 수행한다. 따라서 Level 2 평가가 Level 1 평가보다 덜 보수적이다. Level 2평가에서 위험도지표가 1 보다 작으면 생태계의 건전성이 유지된다는 결론을 내리고 평가를 종료하고, 1보다 크면 Level 3 평가를 수행한다, Level 3 평가는 부지 특성적 데이터를 고려하는 상세평가단계로, 동식물 그룹별 평가 대신 부지 대표적 동식물에 대한 개별적 선량평가를 수행하며, 대표적 동식물의 종류 및 크기, 거주인자, 전이계수, 평형분배계수에 대한 부지 특성적인 값을 사용한다. 또한 Level 3 평가 단계에서는 전이계수, 평형분배계수, 환경매체농도 (토양농도 또는 물의 농도)에 대한 개별 동식물의 피폭 선량률에 대한 불확실도 분석을 선택적으로 수행할 수 있다. 적용 가능한 확률밀도함수는 정규분포, 로그정규분포, 균일분포, 지수분포의 4가지이다. 국제원자력기구의 EMRAS II (Environmental Modeling for Radiation Safety) 모델 시나리오 비교 공동연구에 참가하여 K-BIOTA의 적용성을 검증하였다. 그 결과로 K-BIOTA는 다양한 오염 환경에서 거주하는 야생동식물의 방사선 영향을 평가하는데 유용함이 입증되었다.
