It is assumed that menarche is affected not only by the biological factors such as nutrition and genetic heritage, but also it is affected by other socio-cultural environmental factors including weather, geographic location, education and level of modernization. Also recent trend of menarche in Korea indicates that a lot of discussion are being generated to the need of sex education as a part of formal school education. The purpose of this study is to develop the school health education program by determine the age of menarche, the factors relavant to time of menarche and psycho-mental state of students at the time in menarche and investigate the present state of school health education relate to menarche of adolescents. The total number of 732 girls was drown from first, second and third grades of 4 middle schools in Seoul. For the data collection the survey was conducted during the period from May 1 to May 20, 1982 by using prepared questionair. The major results are summarized as follow; 1. Mean age at menarche and the percent distribution of menarche experienced. It was observed that about 68.7% of sampled students have been experienced menarche at the time interviewed. For the each group, age at menarche is revealed that among the students about 37.8% are experienced menarche for under 12 years old group, 62.1% for 13 year-old group, 80.6％ for 14 year-old group and 95.5% for over 15 years old. In sum it was found that the mean age at menarche was 12.3 years old, ranged from age at 10 as earlist the age at 15 as latest. 2. Variables associated with age at menarche. 1) There was tendency those student who belong to upper class economic status have had menarche earlier than those student who belong to lower class. Therefore, economic status is closely related to age at menarche. 2) In time of mother's education level, it is also found that those students whose mother's education levels from high school and college are experienced menarche earlier than those students whose mother's education levels from primary school and no-education. 3) However, in connection with home discipline, there was no significant relationship between age at menarche and home disciplines which are being treated "Rigid", "Moderated ", "Indifferent". 4) Degree of communication between parents and daughter about sex matters was found to be associated each others in determination of age at menarche. 5) It was found that high association between mother's menarche age and their daughter's menarche age was observed. Mother's age at menarche earlier trend to be shown also as earlier of their daughters. 6) Those students belong to "D & E" of physical substantiality index are trend to be earlier in menarche than those students in the index "A & B". 3. Psycho-mental state at the time of menarche. Out of the total students 68.2% had at least one or more than one of subjective symptoms. Shyness was shown as most higher prevalent symptom and others are fear, emotional instability, unpleasant feeling, depression, radical behavior, inferior complex and satisfaction appeared. Very few cases are appeared be guilty and stealing feeling. 4. The present status of school health education program related to menarche. As to the source of information about menarche, teacher was a main source with average index 5.88 and the other informants were mother & family member, friends, books and magagines, movies, television, and radio. For the problem solving at menarche, mother & family members were subject to discussion with an average index 6.02 as high. The others for discuss and knowledge about menarche were books, magagine, friends, teachers, and self-learning based on own experienced. The time of learning about menarche, it was learned as highest percentage with 43.2% at a 6 grades of primary school, middle school with 34.4%, 5 grade of primary school with 18.2%, and 4 grade of primary school with 4.0% respectively.

We can't deny Korean EE has basically developed on the basis of Environmental Possibilism (Environmental management or Reformism) in lots of aspects. I would show three representative proofs here, the first, the philosophy of Korean EE has been mainly focused on dichotomy of human-techno centrism and eco-centrism with no considering other alternative environmentalism since 4th Formal Curriculum, 1981. The second, simultaneously, the concept of EE has not distinguished from it of Science education. (Furthermore, unfortunately some says EE has been a part of Science education, although there should be many differences on its contextual aspect.) And the third one is that the limit of possibilism which market economists have worried, has scarcely mentioned in various kinds of EE-related teaching materials. Possibilism is basically likely to be accompanied by science and economics-oriented approach, and in this aspect this dichotomy, human-techno centrism and eco-centrism, has come from perspectives of Economical development process and over-addicted belief to Science. So it is enough to say that Korean EE has basically developed with biased to Environmental possibilism, in other words, biased to preference to it. And I'll critically focus on these two axes of possibilism, Science and Economics and its dichotomy. Of course, we should accept there are so many same parts in its contents between EE and Science, but we should know its contextual differences for triangular position of environmentalism suitable to EE and also overcome science-dependant approach to EE. Although science-dependant approach to EE and dichotomy could provide some tools for clearing up the causes of environmental problem, especially always it has insisted fundamental causes of environmental problem originated in human faults and over-use of eco-source or over-economic development, but now it is old-fashioned discourse, furthermore it come to have unavoidable limits in the debates of problem-solving mechanism to environmental problems. The paramount important thing is to supply the ways or thoughtful mechanism for solving or coordinating the Environmental problems, not just searching for cause of it. But scientific approach and its dichotomy based on possibilism have continuously born cause & effect in EE-related discourse. So there are so much needs to transfer from continuous bearing of cause & effect to constructive alternatives at least in environmentalism of EE. Traditionally, dichotomical division in EE Environmentalism, human-techno centrism and eco-centrism, couldn't have Provided any answers to our real society, it just gives us only cause & effects of Environmental problems. And also we can't find the description on the limits of capitalism market approach to Environmental problems especially in Korean EE text books, other teaching materials and its teaching-learning process, although market approach economist has been proved its fault beyond its functional merits as Environmental management tools. So we should introduce other alternative Environmental philosophy instead of Possibilism such as eco-socialism insisted by Schmacher M. and Boochin etc, or marxist-environmentalism for relative and comparative views to market-thought such as commodification. In this aspect we need to accept Oriental philosophy based on moderation(中庸) as new another alternatives with the reflection that we have recognized monism as representative Oriental philosophical environmentalism. Fundamentally monism has done its role with providing relative concepts to Dichotomy Enlightenment, but we can't say it has been core concept for understanding of oriental environmentalism, and we can't distinguish monism from oriental philosophy itself, just because oriental thought itself was basically monism. So conceptual difference should be recognized between EE and Science education in teaching-learning process on the basis of life-philosophy(Philosophie des Lebens) from epistemology. For this transformation, we should introduce existentialism in Science education, in other words, only existential Science education based on phenomenology or interpretivism can be EE. And simultaneously we need some ways for overcoming of scientific foundationalism which has been tradition making science not stand on existentialism, formulating and featuring of almost all of natural things and its phenomenon from after enlightenment in western world, but it has malfunctioned in fixing conception of science just into essentialism itself. And we also introduce integrated approach to science and society for EE like STS. Those are ways for overcoming of Environmental possibilism in EE.

The purpose of this study was to analyse the problems of 'Science Inquiry Experiment Contest(SIEC)' which was one of 8 programs of 'The 2nd Student Science Inquiry Olympic Meet(SSIOM)'. The results and conclusions of this study were as follows: 1. It needs to reconsider the role of practical work within science experiment because practical work skills form one of the mainstays in current science. But the assessment of students' laboratory skills in the contest was made little account of. It is necessary to remind of what it means to be 'good at science'. There are two aspects: knowing and doing. Both are important and, in certain respects, quite distinct. Doing science is more of a craft activity, relying more on craft skill and tacit knowledge than on the conscious application of explicit knowledge. Doing science is also divided into two aspects, 'process' and 'skill' by many science educators. 2. The report's and checklist's assessment items were overlapped. Therefore it was suggested that the checklist assessment items were set limit to the students' acts which can't be found in reports. It is important to identify those activities which produce a permanent assessable product, and those which do not. Skills connected with recording and reporting are likely to produce permanent evidence which can be evaluated after the experiment. Those connected with manipulative skills involving processes are more ephemeral and need to be assessed as they occur. The division of student's experimental skills will contribute to the accurate assess of student's scientific inquiry experimental ability. 3. There was a wide difference among the scores of one participant recorded by three evaluators. This means that there was no concrete discussion among the evaluators before the contest. Despite the items of the checklists were set by preparers of the contest experiments, the concrete discussions before the contest were necessary because students' experimental acts were very diverse. There is a variety of scientific skills. So it is necessary to assess the performance of individual students in a range of skills. But the most of the difficulties in the assessment of skills arise from the interaction between measurement and the use. To overcome the difficulties, not only must the mark needed for each skill be recorded, something which all examination groups obviously need, but also a description of the work that the student did when the skill was assessed must also be given, and not all groups need this. Fuller details must also be available for the purposes of moderation. This is a requirement for all students that there must be provision for samples of any end-product or other tangible form of evidence of candidates' work to be submitted for inspection. This is rather important if one is to be as fair as possible to students because, not only can this work be made available to moderators if necessary, but also it can be used to help in arriving at common standards among several evaluators, and in ensuring consistent standards from one evaluator over the assessment period. This need arises because there are problems associated with assessing different students on the same skill in different activities. 4. Most of the students' reports were assessed intuitively by the evaluators despite the assessment items were established concretely by preparers of the experiment. This result means that the evaluators were new to grasp the essence of the established assessment items of the experiment report and that the students' assessment scores were short of objectivity. Lastly, there are suggestions from the results and the conclusions. The students' experimental acts which were difficult to observe because they occur in a flash and which can be easily imitated should be excluded from the assessment items. Evaluators are likely to miss the time to observe the acts, and the students who are assessed later have more opportunity to practise the skill which is being assessed. It is necessary to be aware of these problems and try to reduce their influence or remove them. The skills and processes analysis has made a very useful checklist for scientific inquiry experiment assessment. But in itself it is of little value. It must be seen alongside the other vital attributes needed in the making of a good scientist, the affective aspects of commitment and confidence, the personal insights which come both through formal and informal learning, and the tacit knowledge that comes through experience, both structured and acquired in play. These four aspects must be continually interacting, in a flexible and individualistic way, throughout the scientific education of students. An increasing ability to be good at science, to be good at doing investigational practical work, will be gained through continually, successively, but often unpredictably, developing more experience, developing more insights, developing more skills, and producing more confidence and commitment.

Small-and-medium sized enterprises(SMEs) represent quite a large proportion of the industry as a whole in terms of the number of enterprises or employees. However researches on information system so far have focused on large companies, probably because SMEs were not so active in introducing information systems as larger enterprises. SMEs are now increasingly bringing in information systems such as ERP(Enterprise Resource Planning Systems) and some of the companies already entered the stage of ongoing use. Accordingly, researches should deal with the use of information systems by SME s operating under different conditions from large companies. This study examined factors and mechanism inducing faithful appropriation of information systems, in particular integrative systems such as ERP, in view of individuals` active feedback-seeking behavior. There are three factors expected to affect end users` feedback-seeking behavior for faithful appropriation of information systems. They are management support, peer IT champ support, and IT staff support. The main focus of the study is on how these factors affect feedback-seeking behavior and whether the feedback-seeking behavior plays the role of mediator for realizing faithful appropriation of information systems by end users. To examine the research model and the hypotheses, this study employed an empirical method based on a field survey. The survey used measurements mostly employed and verified by previous researches, while some of the measurements had gone through minor modifications for the purpose of the study. The survey respondents are individual employees of SMEs that have been using ERP for one year or longer. To prevent common method bias, Task-Technology Fit items used as the control variable were made to be answered by different respondents. In total, 127 pairs of valid questionnaires were collected and used for the analysis. The PLS(Partial Least Squares) approach to structural equation modeling(PLS-Graph v.3.0) was used as our data analysis strategy because of its ability to model both formative and reflective latent constructs under small-and medium-size samples. The analysis shows Reliability, Construct Validity and Discriminant Validity are appropriate. The path analysis results are as follows; first, the more there is peer IT champ support, the more the end user is likely to show feedback-seeking behavior(path-coefficient=0.230, t=2.28, p<0.05). In other words, if colleagues proficient in information system use recognize the importance of their help, pass on what they have found to be an effective way of using the system or correct others' misuse, ordinary end users will be able to seek feedback on the faithfulness of their appropriation of information system without hesitation, because they know the convenience of getting help. Second, management support encourages ordinary end users to seek more feedback(path-coefficient=0.271, t=3.06, p<0.01) by affecting the end users' perceived value of feedback(path-coefficient=0.401, t=6.01, p<0.01). Management support is far more influential than other factors that when the management of an SME well understands the benefit of ERP, promotes its faithful appropriation and pays attention to employees' satisfaction with the system, employees will make deliberate efforts for faithful appropriation of the system. However, the third factor, IT staff support was found not to be conducive to feedback-seeking behavior from end users(path-coefficient=0.174, t=1.83). This is partly attributable to the fundamental reason that there is little support for end users from IT staff in SMEs. Even when IT staff provides support, end users may find it less important than that from coworkers more familiar with the end users' job. Meanwhile, the more end users seek feedback and attempt to find ways of faithful appropriation of information systems, the more likely the users will be able to deploy the system according to the purpose the system was originally meant for(path-coefficient=0.35, t=2.88, p<0.01). Finally, the mediation effect analysis confirmed the mediation effect of feedback-seeking behavior. By confirming the mediation effect of feedback-seeking behavior, this study draws attention to the importance of feedback-seeking behavior that has long been overlooked in research about information system use. This study also explores the factors that promote feedback-seeking behavior which in result could affect end user`s faithful appropriation of information systems. In addition, this study provides insight about which inducements or resources SMEs should offer to promote individual users' feedback-seeking behavior when formal and sufficient support from IT staff or an outside information system provider is hardly expected. As the study results show, under the business environment of SMEs, help from skilled colleagues and the management plays a critical role. Therefore, SMEs should seriously consider how to utilize skilled peer information system users, while the management should pay keen attention to end users and support them to make the most of information systems.

영어 논문의 작성 능력은 오늘날 공학도들에게 필수적으로 요구되는 자질이다. 주요 해외 저널에 얼마나 많은 논문이 게재되었느냐가 학문적 성과를 평가하는 주된 척도라는 점과 주요 해외 저널들이 보다 많은 독자들을 대상으로 하기 위하여 영어로 쓰여진다는 점 때문에 영어 논문 작성 능력에 대한 필요성은 한국을 포함한 영어가 모국어가 아닌 모든 국가들에서 강조되고 있는 실정이다. 그러나, 불행히도 한국에 있는 이공계 대학들은 석/박사 연구원들의 영어 논문 작성 능력 향상을 위한 정규적인 교육 과정을 제공하고 있지 못하다. 이러한 상황을 더욱 악화시키는 것은 구체적인 기술 논문 작성 방법론에 대한 문헌이 부족하다는 점이다. 원어민(Native Speaker)을 위한 기술 논문 작성 방법론에 대한 문헌이나 EFL 학습자들을 위한 일반적인 영어 작문법에 대한 문헌은 많이 있지만, EFL 학습자들을 위한 기술 논문 작성법에 대한 지침서나 문헌은 찾기 힘들다. 따라서, 본 보고서의 목적은 두 가지로 나누어 볼 수 있다. 첫째, 영문 기술 논문 작성에 대한 교육 방법론이 생소한 한국에서 이공계 연구원을 대상으로 강의를 하고 있는 EFL 강사들에게 제기될 수 있는 일반적인 논제들을 제시한다. 이 논제들은 적절한 강의 접근법(Teaching Approach), 최적의 학생 배치(Class Arrangement), 그리고 컴퓨터 학습 도구의 활용뿐 아니라 대조 수사학(Contrastive Rhetoric)의 중요성에 대한 내용을 포함한다. 둘째, 실제적인 강의 제안서도 제시한다. 본 강의 제안서는 기술 논문 작성법 강의 수강생들의 작문 샘플에 대한 분석 결과와 기술 논문 작성법에 대한 자가 진단 설문 응답 분석 결과를 근거로 작성하였고, 한국인 EFL 학습자가 기술 논문 교육 과정을 통하여 문법(Grammar), 과정(Process), 장르 기술(Genre Skills) 등을 골고루 개발할 수 있도록 하였다. 본 보고서는 EFL 기술 논문 과정의 개발에 대한 여러 일반적인 논점들을 공유함으로써 기술논문 교육방법론 연구가 부족한 한국의 공학 교육계에 하나의 사례를 제시하였다.

이 연구는 보일의 법칙과 샤를의 법칙에 대한 중학교 1학년 학생들의 인지수준과 배경 요인에 따른 개념 문제 해결력과 수리 문제 해결력을 비교한 것이다. 연구를 위해 개념과 수리 문제 해결력 검사지를 개발하여, 중학생들의 인지수준과 배경 요인에 따른 개념 문제 해결력과 수리 문제 해결력을 비교하고, 기억 보유 효과를 알아보았으며, 어떠한 개념을 가지고 문제를 해결하였는지 분석하였다. 연구 결과, 모든 인지수준에서 개념 문제 해결력이 수리 문제 해결력보다 높았으며, 구체적 조작기와 과도기의 중학생들의 경우 그 차이가 통계적으로 유의미하였다. 개념 문제 해결력과 수리 문제 해결력에 대한 기억 보유 효과 비교에서 형식적 조작기 중학생들은 기억 보유 효과가 있었다. 중학생들의 배경 요인에 따른 개념 문제 해결력과 수리 문제 해결력 비교에서 사교육을 받은 중학생들과 받지 않은 중학생들 사이의 개념 문제 해결력과 수리 문제 해결력에 통계적으로 유의미한 차이는 없었다. 그러나 과학 활동 경험과 과학 관련 진로 희망 여부에서는 과학 활동 경험이 있고 과학 관련 진로를 희망하는 중학생들이 그렇지 않은 중학생들보다 개념 문제 해결력과 수리 문제 해결력이 모두 통계적으로 유의미하게 높았다. 중학생들의 문제 해결 과정을 분석해 본 결과, 거시적인 현상을 단순히 기억하여 과학적 개념에 대한 올바른 이해 없이 문제를 해결하려는 경향이 있었다. 그러므로 중학생들의 비과학적인 개념을 사전에 파악하여 이를 과학적인 개념으로 바꿀 수 있는 교수-학습 전략이 필요하다.

최근 연구에 따르면 학생들의 진로 선택에서 비정규학습이 정규학습 못지않게 영향을 주고 있는 것으로 나타났다. 다양한 형태의 비정규 과학교육 활동이 시행되고 있는 가운데, 2004년 국내에서는 한국공학 한림원을 중심으로 기업의 공학 기술인이 학교 현장에 찾아가 학생들과 함께 과학 실험, 공작 활동을 하는 것이 새롭게 시도되었다. 이러한 '주니어 공학기술 교실' 사업은 한국공학한림원에서 과학기술자에 대한 올바른 인식과 첨단 과학기술에 대한 이해 증진을 위해 민간주도로 지역의 과학기술자가 초${\cdot}$중등 학교를 직접 방문하여 과학기술 교육을 지원하는 형식으로 시행되고 있다. 2004년 현재 대기업과 중소기업 17개 기업이 참여하고 있다. 주니어 공학기술교실에서는 공학 기술인이 학생을 가르치는 교사(이하 기업 교사)로, 현직 교사는 기업 교사와 학교 현장을 중계하는 매개자 역할을 하게 된다. 새롭게 시도되는 비정규 과학 활동이라는 점에서 이 프로그램의 직접적인 운영자인 기업 교사와 이를 바라보는 학교 현직 교사의 인식은 매우 중요하다. 본 연구에서는 비정규 학습에 대한 현직 교사와 기업 교사의 인식을 조사함으로써, 기업 교사가 학교 현장에 참여하는 비정규 과학교육 활동에 대한 시사점을 알아보고자 하였다. 설문과 현장 수업 참관을 통해 조사한 결과, 기업 교사와 현장 교사 모두 본 사업의 취지에 공감하였으며, 사업의 시행 결과에 매우 만족한 것으로 나타났다. 하지만 일부 기업 교사는 교재와 교구, 학교와 기업의 협조 분위기에 불만족을 나타내기도 하였다. 또한 현장 교사와 기업 교사 모두 프로그램의 적절성이 주니어 공학기술 교실과 길은 비정규 과학교육 사업의 성공과 실패를 좌우한다고 생각하였다. '주니어 공학기술 교실'과 같은 비정규 과학교육 활동이 효과적으로 시행되고 사회적으로 확산되기 위해서는 적절한 프로그램의 개발 노력이 무엇보다 중요하며, 학교와 현직 교사 등 교육계의 적극적인 수용 및 활용 의지가 더욱 필요한 것으로 보인다.
