  • 본 연구의 목적은 인지 수준에 따른 고등학생들의 지구와 달의 운동에 대한 생각을 알아보는 데 있다. 연구를 수행하기 위하여 경기도 수원시에 소재한 일반계 고등학교 10학년 학생 73명을 선정하여, 인지 사고 수준이 상, 중, 하인 학생 5명을 표집, 질적 분석의 대상으로 삼았다. 연구 결과, 학생의 인지 수준이 높을수록 지구와 달의 공전과 자전에 대한 개념이 비교적 논리적이고 과학적으로 정립되어 있었다. 인지 수준이 중간인 학생의 경우, 보편적으로 수업 시간에 학습한 내용을 비판 없이 무조건 수용하고 암기하려는 수동적인 학습 태도를 가지고 있었으며 파지된 개념이 확장되지 못하고 쉽게 망각되었다. 또한, 지구와 달의 운동을 설명하는 과정에서 유년적 개념 및 직관과 오인이 나타났으며 논리적 오류를 범하는 경우도 있었다. 특히 달의 위상 및 계절 변화의 원인에 대한 설명에서 학생들의 오개념이 심한 것으로 나타났다. 인지 수준이 낮은 학생들은 대체로 과학을 비롯한 학업 성취도가 낮음을 이유로 의욕적인 논리적 사고를 하려고 하지 않았으며, 개념을 인지하고자 하는 태도에서도 소극적이었고, 수동적인 ‘학습된 무기력’이 나타났다.

  • 교육의 질을 결정하는 주요 요소 중에서 가장 핵심적인 역할을 하는 것은 교사이다. 그러므로 교육의 질을 높이기 위해서는 교사의 질을 향상시켜야 한다. 교사의 자질은 교직에서 요구되는 기능 즉, 교수 활동 뿐 아니라 생활지도, 학급경영을 수행할 수 있는 능력을 의미한다. 본 연구의 목적은 초, 중, 고등학생들이 원하는 과학 교사의 자질을 분석하고자 하는 것이다. 이를 위하여 초, 중, 고 학생 332명을 대상으로 선호하는 과학 교사의 자질과 기피하는 과학 교사의 자질을 개방형으로 기술하도록 하였다. 그 결과 얻어진 개념들을 언어 네트워크 분석법으로 분석하였다. 이 연구의 결론은 1) 학생들은 선호하는 과학 교사의 자질은 다양한 것으로 나타났다. 이는 학생들이 과학 교사를 긍정적으로 생각하는 면이 많은 것을 의미한다. 또한 학생들에게 다양한 면에서 긍정적인 또는 선호하는 교사의 자질을 보여 줄 수 있다는 것이다. 2) 학생들은 실험을 통해서 과학 현상과 이론, 개념을 이해하고 설명해주길 바라는 것으로 나타났다. 과학 수업에서 학생들은 직접적인 활동이나 체험을 선호하였다. 3) 학생들은 과학 교사의 자질에서 수업과 관련된 내용을 중요시하고 있다. 과학 교수 학습 방법의 개선과 학생들을 긍정적으로 대함으로써 학생들의 과학 교사 나아가 과학에 대한 이미지를 높여야 할 것이다. 이 연구 결과를 기반으로 하여 과학 교사의 구체적인 교수 학습 방법에 따른 이미지 연구가 추가적으로 이루어지길 기대한다.

  • This historical research was conducted to analyze and categorize the titles which were presented in the journal, The Korean Nurse, from August 1962 to October 1995. Titles which were published with the purpose of educating graduate nurses and to update 0 their nursing knowledge to improve professional practice were included. There were 348 articles published from the beginning of publication in August, 1962 to October, 1995. All of the journals were reviewed except nine missing journals which were not available in any library. According to the characteristics of the articles in the periodical, the articles were divided into three periods. In each of the three peroids there were five categories: Subject, Clinical Practice, Fundamentals of Nursing Science, Nursing Administration, Others. These categories were adopted from Kim's(1994) division system which was developed to analyze nurse's insurance education program. The special feature peroid was from August, 1962 to December, 1974. In this period the articles were presented in an unorganized manner in the area of special feature or main issue. The largest area was the subject category(44%). The second largest area wes the fundamental of nursing science category(31%). From May, 1975 to December, 1977, the articles with the educational purposes were published in a designated area called continuing education. This period was labelled as the continuing education period. Among the published articles in this period, 45% focused on the subject category and 45% on the fundamentals of nursing science category. In this period the articles were focusing on nurses 'work in specific areas such as industry, nurses' aid schools, and nursing administration, articles on physical assessment first started to appear. The written continuing education period was from January 1978 to October, 1995. All the educational articles published in this area were analyzed and categorized into five areas as for the other periods. 48% of the articles focused on the subject category. In the mid-eighties, the term nurse specialist first.appeared and ten years later in 1990, the titles were subdivided into more specific titles, such as, home nursing, industrial nursing, emergency nursing, 23% were in the fundamental nursing science category and they dealt with nursing process, nursing theories, theory development. For the content analysis, three articles, one from each period, dealing with cardiovscular diseases were selected for comparsion. First, the special feature period, the title of the article was on diet therapy for cardiovascular disease patients, but instead the content was about rest, hygiene, medication, observation. They recommended rings to prevent bed sores, which is now considered as a cause for bed sores. In the continuing education period, the content was more focused on rehabilitation rather than general nursing .care. It became more specific, systematic, and organized compared with the special feature period. In the written continuing education period, the focus was on rehabilitation, not broadly, but very specifically on exercise. The further research on the content analysis is recommended along with a comparison of the trends in the Journal of Nurses Academic Society.

  • The purposes of this study was to find aesthetical-ethical paradigm of care ethics by understanding the unique moral character of care as an art and to suggest the optimal direction of nursing ethics. Method: This study used meaning-heuristic and -interpretive methods of hermeneutics based on philosophical aesthetic theory; Baumgarten's aesthetics, Schiller's theory of aesthetical education and Kant's theory of aesthetical judgement. Result: The concept of care implied aesthetical and ethical character; caring as an art was related to moral feeling based on human dignity und emotional communication in interpersonal-relationship. Caring as an art was interpreted as a moral ideal for the promotion of the humanity und the interaction in personal-relationship according to nursing theories. Philosophical aesthetics could provide the theoretical base for the interpretation of caring as an art. The proper paradigm of care ethics in nursing could be found in character-trait ethics and communication ethics according to the philosophical aesthetics. Conclusion: This study could show aesthetical-ethical paradigm of care ethics in nursing by the heuristic interpretation of caring as an art according to the philosophical aesthetics

  • The purpose of this study is to understand how to activate field training internships through former researches related to training internships. The concept of field training is the same as education of work experience. Students have experienced the skills of practical jobs in the tourism industry and could enhance acquisition of professional theories. According to domestic former researches, students who participated in hotel field practice hardly satisfied with internships due to unreasonable duties, burdens and circumstances regardless of efficiency of school curriculum. Also, they showed dissatisfaction with compensation. However, foreign studies have only focused on communication between hotels and schools. Finally, in order to activate industrial field training internships, schools and hotels have more delicate harmonization to address training internship problems. In addition, promoting field training internships must include proper incentives and must be supported by school. And also the hotel management must offer incentives to the students who are under field training internships in the hotel. From internship programs, students could get much more benefits in hotel job application.

  • By comparison and analysis of the optical data of the two galactic clusters of Pleiades and h and x Persei and the radio data of the HI gas clouds which are related with those two clusters, the relative motions of those gas clouds with retpect to the two clusters were obtained. The three theories on the acceleration of HI gas cloud surrounding a star cluster by Blaauw. Oort and Spitzer, and Kahn were examined with the above obtained kinetic data of the Pleiades and the h and x Penei clouds. And it was shown that Blaauw's theory is applicable to the h and x Persoi clouds but not to the Pleiades, that Dart and Spitzer's theory can explain the motions of both clouds, and that Kahn's theory needs more improvement to be a complete one.

  • In order to cope with various issues about access to public health system of Korean medicine and reformation of college curriculum and argument of pseudoscience on Korean medicine etc., a new definition of Korean medicine was devised. Two ways of approach were tried through analysis of precedent cases of definition on traditional medicine firstly and analysis on concept and logic of Korean medicine secondly. As a result, Korean medicine can be defined as a science of theories and application techniques for maintaining health and diagnosing, treating and preventing conditions、causes、prognosis of diseases or damages based on the correlative and complicated understanding about the structure and function of mind and body out of human lives under the environment and society. This definition can be used as a basis to derive legal rights or scope in area of research and education policies and social institutions of the Korean medicine and to confront scientification criticism hereafter.

  • An unexplained acceleration on the order of 10-8 cm s-2, which is close to cH, where c is the speed of light and H is the Hubble constant, is detected in gravitationally bound systems of different scales, from the solar system to clusters of galaxies. We found that any test body located inside a fractal structure with fractal dimension D = 2 experiences acceleration of the same order and confirmed the previous work that photons propagating through this structure decrease the frequency owing to gravitational redshift. The acceleration can be directed against the movement of the test body. The fractal distribution of the matter should be at scales of at least hundreds of megaparsecs to a few gigaparsecs for the existence of this acceleration.

  • Purpose: The purpose of this study was to develop a program for anger management based on self-efficacy. Methods: In this study, four types of approaches to enhance anger control were developed; 1) a role play for vicarious experiences; 2) an assertive training for anger expression; 3) a 30-minute long education program & a 20-minute long telephone call coaching for verbal persuasion; and 4) a booklet for anger management and self care behaviors. One group pretest-posttest design was used for evaluating the program. Study subjects were 6 cancer patients undergoing chemotherapy. The group were received a 4-week intervention, 60 ~ 90 minutes a day weekly, and measured the variables at baseline, 4 weeks later. Anger-in, anger-out, and anger-control were measured by STAXI-K. Data was analysed by Wilcoxon using SPSS/WIN 12.0 program. Anger situation was analysed according to primary anger-thoughts and secondary anger-thoughts based on cognitive theories of anger. Results: The program for anger management consisted of a role play, assertive training, education, telephone call coaching and a booklet. The program revealed significantly less Anger-in (Z = -1.997, p = .046), anger-out (Z = -2.207, p = .027). No difference, however, was found in anger control (Z= -1.826, p=.068). Conclusion: This evaluation suggested that more assertive training and longer intervention may be needed to maximize anger control.
