Yam has been recognized having the beneficial effects for the prevention of various diseases, such as cancer, immunity, infection and obesity etc. There is increasing consideration to supplement the antioxidant nutrients to make up the lack of the antioxidant nutrient intakes. No study has been reported for the analysis of antioxidant mineral contents and comparison to dietary recommended intake for the sense of health promotion. In our study, we analyzed the contents of antioxidant trace elements (Zn, Mn, Fe, Cu and Se) and Cr contents in cultivated Korean yam powders for evaluation of nutrient intake aspects. We collected the commercial yam powders from six different cultivated areas in the South Korea and measured antioxidant minerals (Zn, Mn, Fe, Cu and Se) and Cr contents using trace element-free plasma spectrometer (ICP) or atomic absorption spectrometer (AAS) after dry-ashing and then wet-acid digestion. The accuracy of mineral analysis method was confirmed by the mineral analysis of standard reference material. Each analyzed element contents in yam were compared to dietary reference intakes of Koreans (KDRIs). The average levels of trace elements (Zn, Mn, Fe, Cu, Se and Cr) in yam powders were 18.3, 11.9, 36.0, 3.7, 1.9 and 1.27 ${\mu}g/g$ yam powder, respectively. The intakes of Zn, Fe, Cu and Se of which KDRIs is determined, are accounted as being up to 23.8%, 55.6%, 32.5% and 236% recommended intake (RI) of KDRIs, if daily yam supplementation (50 g) of commercial instruction would be considered. The intake of Mn is about 25% adequate intake (AI) of KDRIs with the daily supplementation of yam powder. Most of mineral intakes from daily yam supplementation were with the range of non-detectable to <10% upper limit (UL) level, which is very much safe. The study results show that daily supplementation of Korean yam power is beneficial to provide the supplemental nutrient intake and also is safe, if the suggested dosage would be considered.

Purpose: To evaluate community health nursing practice by nursing students for basic data to improve nursing practice education, and to determine the clinical practice experiences of nursing students at public health centers. Method: According to methodological triangulation, all data was collected from March 2001 to June 2001 through prepared questionnaires with 62 Participants, and in depth interviews with 2 Participants, and content analysis with 8 Participants. Results: 1. Clinical practice content was needed to make up professionally. 2. Clinical practice instructor was satisfied with teaching by community health nursing professor, but not by public health center nurse. 3. Clinical environment was perceived as good. 4. Clinical practice time was perceived suitable, but practice evaluation was given a low grade. 5. Experience of nursing students was grouped into 9 categories and 20 themes. 9 Categories are as follows: change of public health center image, difficulty in the personal relationship, positive personal relationships, doubt about the attitude, doubt about the task, tension, worth, ambivalance of the conference, feeling about the end stage of the clinical practice. Twenty themes are stereotypic of the public health care center: recognition, difficulty between tasks and interrelationships with the clients, decrease of self esteem due to deficiency of trust with the students, exchange of feelings in the relationships, the situation of clients was not considered, feelings were disregarded, not systematic, regarding students as supplementory manpower, independent work but not enough contents, anxiety & fear, self-trust, be skilled in the practice, pragmatic knowledge formation, understanding of the old person, self-study of oneself. live up to the expectation, consider as the job, dissolve the stress and impose burden, feeling the lack regarding active approach in the practice. Conclusion: The students have perceived the need of community health nursing through the clinical practice. Clinical practice of community health nursing requires content supplement, correction of instruction by public center nurses, environmental alteration, evaluation criteria set up. Experience of clinical practice in the public health center was as follows: Getting rid of the stereotype about public health center, nursing students comprehended variety and were worth while to do clinical practice in spite of tension& anxiety and fear. And they thought to be a community nurse someday.

In the past most major accidents resulted in death, but today there is a dramatic increase in the number of people who survive such accidents but who are left with permanent injury. Particularly, children who are inquisitive about their surroundings but immature in their ability to assess danger, are more vulnerable to accidents and their causes as well as to determine attitudes towards prevention. The main objective of the study was to assess the effectiveness of using an accident prevention manual for accident for accident prevention education. The study was a quasi-experimental study using a questionnaire format. The subjects of the study were 393 mothers of children attending six day care centers in Seoul. Data collection was done between May 1 and June 15, 1997. The tools used for the study were a questionnaire developed the researchers and a manual for accident prevention. The collected data were analyzed using SPSS. The results of the study are as follows: 1. Types of accidents included stabbing, bums, falls from heights, choking, falls on slippery surfaces, traffic accidents, drowning, poisoning, and electrical shock in that order of frequency. 2. The main causes of accidents in children were from cosmetics and household medications. 3. The most frequent locations of accidents in the home were the bathroom, kitchen, and stairways in that order. 4. For $90.4\%$ of children safety seats were not used when the ridding in a car. 5. In examining the parents' accident prevention practices, it was found that many parents used only . one electrical outlet for many appliances, tending to overload the electricity lines and that they were not practically concerned bout the flammability of children's pajamas, indicating a less than positive attitude towards fire prevention. 6. The parents had not provided their children with any instruction on accident prevention or on what to do after an accident had occurred. 7. After the use of pamphlet in an accident prevention education program, it was found that there was a statistically significant difference in the degree to which children carried out safety measures (t=14.96, p=.000) and in their safety habits (t=-1.67, p<.1) indicating an effectiveness in this method of education. The results of this study showed that there are many things in a child's environment that can cause accidents and that the possibility of an accident occurring is high. So nurses looking after children should be aware of the need for safety education to prevent accidents in the home and plan to provide appropriate educational material to help parents with this education.

Many problems with the offline class, which is the traditional education type in corporations or universities, were indicated and people hoped that e-learning, which is web-based instruction, would solve these problems. However, e-learning also has weak points in that it should be self-paced and media-based in many ways. Therefore, when considering the good and weak points of offline classes and e-learning, blended learning seems to be necessary. Until now, blended learning has usually been used in corporations, and there have been almost no studies on the effectiveness or management of blended learning in universities. Thus, in this study, I would like to design blended classes, manage them at the level of university classes, and verify the effectiveness of blended classes, by comparing academic achievement, student participation, and student satisfaction. The subject students who signed up for Computer & Technology at C University in 2005 were divided into three study groups: offline class, online class, and blended class. The offline class was taught using the traditional class teaching method. For the online class and the blended class, multimedia contents were developed and a different LMS was used. The results of 13 weeks of teaching are as follows. For the academic achievement in the offline, online and blended classes, there was no statistically significant difference (f=2.387, p=.096). But when comparing the average achievement, the average of the blended class was higher than that of the other classes, so that it can be said that the blended class has positive effects on academic achievement. Second, when comparing the learners' participation in the online class and the blended class, the total posts were 85 and 138 respectively, which shows a considerable difference. The hit counts for each post in the online class and the blended class are 10 and 20, respectively. Moreover, the login counts for subjects are 3 in the online class and 4 in the blended class. In the questionnaire for the students' academic satisfaction in the online class and the blended class, all of the 15 items showed higher satisfaction in the blended class. Considering all these results, if adequate media are properly combined, the blended class is better than either the pure online class or the pure offline class.

본 연구는 기독교 대안학교 교사들이 인식하는 교사의 전문성은 무엇이고 그들의 전문성은 어떻게 성장하는지 찾아보는 것을 목적으로 한다. 전문성은 일반적으로 특정 분야에 필요한 특별한 지식, 기술, 태도를 의미한다. 교사 전문성 역시 주어진 업무를 수행하는데 필요한 능력과 자질, 기술과 행동, 가치를 포함하며, 교사의 생애주기와도 밀접한 관계가 있다. 본 연구는 교사 전문성의 의미와 성장 방식을 탐구하기 위해 설문조사와 면담을 병행한 혼합연구방법으로 자료를 수집하였다. 270여 명의 기독교 대안학교 교사가 참여한 설문조사는 교사의 관심사, 각 전문성 요소의 중요도와 보유 정도, 전문성 개발 노력과 도움 정도를 질문하였다. 심층 면담은 7명의 기독교 대안학교 교사를 대상으로 하였고 이들이 인식하는 교사 전문성의 의미, 교사 자질과 역량, 전문성 성장을 위한 환경을 파악하였다. 분석 결과를 보면 기독교 대안학교 교사들은 기독교적 관점으로 교과를 재구성하는 교과 전문성뿐 아니라 소통, 관계, 소명의식을 전문성으로 강조하였다. 그리고 이들의 전문성 성장에는 소명에 반응하고자 하는 교사의 결단, 지속적인 자기계발, 교사공동체, 자율과 책임이 공존하는 교육환경이 중요한 것으로 나타났다. 결론에서는 교사들의 전문성 성장을 위해서 교사의 생애주기를 고려할 것과 교사 주도적인 전문성 성장의 접근을 제안하였고, 예비교사교육에서 교과 전문성뿐 아니라 소통과 관계능력 향상에 주안점을 둘 것을 강조하였다.

수 지도에 관한 문제는 수학교육의 역사에서 가장 활발하게 논의된 주제로서, 수학적, 철학적, 심리학적, 수학교육학적 측면에서 다양한 관점과 주장이 제기 되었다. 수 개념은 하나의 관점에서 규정될 수 없는 복합적인 개념이며, 그 지도 역시 결코 간단한 문제가 아니다. 그럼에도 불구하고 수 개념 및 그 지도에 관한 대부분의 논의는 수 개념의 한정된 측면을 중심으로 한 것이었다. 본 연구에서는 자연수 개념을 어떻게 지도하는 것이 좋은가 하는 자연수 개념 지도 문제에 대해, 자연수 개념의 제 측면에 대해서 현대 수학교육의 근본적인 이념이 되고 있는 활동주의적 접근을 시도하고자 하였다. 이를 위해 본 연구에서는 자연수 개념의 역사적, 수리철학적 논의와 수 개념의 제측면에 관해 고찰하고, 지식의 활동적 구성과 활동을 통한 자연수 개념의 구성 및 자연수 개념 지도의 활동주의적 접근을 논의한 제 학자들의 입장을 비판적으로 분석하는 가운데 자연수 개념의 제 측면을 의미 있게 지도하기 위한 활동주의적 접근 방안을 연구 제시하였다.
