Based on the thinking that people can understand more clearly when the problem is related with their prior knowledge, the Purpose of this study was to analysis students' informal knowledge, which is constructed through their mathematical experience in the context of real-world situations. According to this purpose, the following research questions were. 1) What is the characteristics of students' informal knowledge about fraction before formal fraction instruction in school? 2) What is the difference of informal knowledge of fraction according to reasoning ability and grade. To investigate these questions, 18 children of first, second and third grade(6 children per each grade) in C elementary school were selected. Among the various concept of fraction, part-whole fraction, quotient fraction, ratio fraction and measure fraction were selected for the interview. I recorded the interview on digital camera, drew up a protocol about interview contents, and analyzed and discussed them after numbering and comment. The conclusions are as follows: First, students already constructed informal knowledge before they learned formal knowledge about fraction. Among students' informal knowledge they knew correct concepts based on formal knowledge, but they also have ideas that would lead to misconceptions. Second, the informal knowledge constructed by children were different according to grade. This is because the informal knowledge is influenced by various experience on learning and everyday life. And the students having higher reasoning ability represented higher levels of knowledge. Third, because children are using informal knowledge from everyday life to learn formal knowledge, we should use these informal knowledge to instruct more efficiently.

A primary task of fire department is maintaining public safety, system maintenance and welfare improvement by protecting life, body and property of a people through prevent and extinguish of the fire in emergency. Rescue part of those affairs has supported by the people but affairs related to the fire examination and investigation could not get it. Although fire examination is a very important part of fire department administration, it has been understood indifferently due to lack of awareness and concern. There are no scientific fire examination because of lacking education study and the whole responsibility capacity about it. There are many things have to be improved at fire examination and investigation system in Korea. Especially, establishment of the whole responsibility post is urgent through assuring professionals to improve accuracy of fire examination and investigation.

The purpose of this study was to investigate the effects of localized muscle fatigue and whole body fatigue on postural control during single-leg stance after impairment induced by heel raise and the Harvard step test. Thirty-eight university students (19 men: age, $20.1{\pm}0.2$ yrs; height, $175.0{\pm}5.23cm$; weight, $66.8{\pm}5.6kg$; body mass index, $21.8{\pm}1.7kg/m^2$, 19 women: age, $20.6{\pm}1.1yrs$ ; height, $163.6{\pm}6.7cm$; weight, $58.8{\pm}4.6kg$; body mass index, $22.0{\pm}2.2kg/m^2$) were participated in this study. Subjects performed a series of single-leg postural tasks prior to, following, and 24 hours after completing: heel raise or the Harvard step test. This study showed that the root mean squared distance and velocity in the anteroposterior and mediolateral planes of the center of pressure decreased significantly due to heel raise exercise-induced fatigue. Furthermore, the root mean squared distance in the anteroposterior and mediolateral planes, and the 95% confidence ellipse area of the center of pressure also decreased significantly 24 hours after completing the Harvard step test. In conclusion, this study showed that both heel raise exercise- and Harvard step exercise-induced fatigue affects postural control during single-leg stance in AP and ML planes. Furthermore, this study suggests that changes in the postural control strategy may have occurred after the fatigue protocols during single-leg stance. Also vision can attenuate the postural deficits associated with the fatigues. In order to clarify these results, further studies using other equipment and variables are necessary.

Some children can construct a basic concept of addition and subtraction during the preschool years. Children start to experience mathematics via numbers and their of operations and contact with various contexts of addition and subtraction. In special, word problems reflect mathematics which is appliable to real life. In this paper, I analyse the types of word problems in text book and its students' responses. First, I analyse the types of addition word problems which consist of change add-into situations and part-part-whole situations. Second, I analyse the types of subtraction word problems which consist of change take-away situations, compare situations and equalize situations. Third, I analyse the students' responses by the types of word problems in addition and subtraction. And 115 2nd grade elementary school students participated in this survey. The following results have been drawn from this study. First, the proposition of word problems of part-part-whole situations is higher than that of change add-into situations and the proposition of word problems of take-away situations is higher than that of compare situations and equalize situations. According to the analysis about students' responses, It is no difference between change add-into situations and part-part-whole situations. But the proposition of word problems of take-away situations is higher than that of compare situations and equalize situations. This results from word problems which contain unnecessary information in problem. So, we have to present the various word problems to students.

According to the records that all the people in our country were taught the way of braiding the hair and hatting in the first year of 'Tangun' (the founding father of the Korean nation) and that the discipline between sovereign and subject, man and woman, and the standard of food, drink and dwelling were originated from that year, it seems that all the people in our country had lived with keeping a certain standard of food, clothing and shelter, and with maintaining the order in life from ancient times. So, our country have been called 'the Eastern Land of Courtesy' and also regarded as 'the country of the true gentle-man' which was characterized as the custom of a humane, and as the country that had the immortality since a benevolent person lived to a great age. Thus, all the people in our country have lived with keeping and maintaining a certain standard of all aspects in life, and the philosophy in life that we have today was established by the influences of our characteristic thought, Confucianism, Buddhism, Taoism and Christianity, especially the life style in the Chosun Dynasty Period have strong influence on our today life. Thus, the contents concerned with the standard of custume life among those of all life in the Chosun Dynasty Period was studied, and clothes itself is unable to give expression to its ends but when the relationship that is, the inter-harmony among clothes, the body which will be dressed in, and the inherent psyche in that body is formed, then the ends, the complete beauty will be expressed. Though there were many studies dealt with clothes itself, no one was concerned with the all kinds of standard in activities that the dresser should keep, so the purpose of this article is that as above. The literature search is used as the research method. The eight books, 'Noneo' (the Analects of Confucius), 'Yeogi' (the Book of Courtesy), 'Sohak' (the book of Precepts for child-ren), 'Yeosaseo'(the Women's Four Books), 'Sasojeol'(Korean Scholars' Minor Principles) 'Eonhaenaehoon' (Private Moral Instructions for Women), 'Woo-am seonsaeng kyenyeoseo' (Master Woo-am's Cautions for Girls) and 'Kyoobangkasa' (the Lyric Lines of the Boudoir) that had influenced the whole field of life in the Chosun Dynasty Period are analyzed, selected and finally arranged for studyilng the foundation of culture of the clothing and for helping to that culture in modern and future life. The results are as follows: 1. The standard of the clothing life in the Chosun Dynasty Period had deeply rooted in the teaching of confucianism, but also had been influenced by the custom which rooted in our people. 2. There is the emphasis upon the trinity among mind, clothes and activities in the clothing life. 3. The clothing and hat have to be dressed symmetrically in full of all required elements, 4. There is the harmony between the clothing with hat and environments or surroundings. 5. The true elegance in the clothing life will be realized not by the exterior outfit but by the interior outfit with the attitude of chastiny.

The Industrial Revolution brought great development to the whole human history by the improvement of productive capacity. However, high speed development absorbed just on growth gave rise to resource depletion attack and economical inequality. If it might be neglected human society will meet unsustainable development situation. So UN has made effort to make sustainable development(SD) through global band together. SD concept considers it important to promote current development not giving damage to next generation's development. Then economy, environment and social integration should be harmonized and it demands governance for its actualization. SD gets to be a matter of common interest in education. New Millenium development Goals make African poor countries that are in blind spots of development advance toward gradual sustainable development by supporting programmes to these countries. Thus sustainable development education(SDE) is for future. It has an aim to give suitable education for all people who are all over the world. SDE tries to make health society and successful economical life for all. The concept of SD is found in the essential aims of Christian school and Christian education seeking justice and shalom. Christians are called as transformers for servant mission giving recover in corrupt world. Firstly, Christian school practise this mission making students think on Christian perspectives. Then it makes students serve for environment, economical fairness, social integration with servant mission. Also Christian school has a mission to seek both justice and shalom as a praxis beyond the intellectual dimension of education until fulfilling justice and shalom for all who are all over the world. Thus it can be that Christian school is an important educational institution for realizing sustainable development in that it is always to seek justice and shalom through restoration on the Christian educational perspective.

One of the biggest problems of Nursing Education in Korea is the division among nursing education programs of the last 3 and 4 years. To solve this problem, Nursing community must do variable trials to achieve the unity of a 4-year educational program. With this, we need to observe the phenomena and reality of the present 4-year nursing educational program that we have. The object of this study is to analyse and discuss that we have. The object of this study is to analyse and discuss the problems and future strategies of 4-year Nursing Baccalaureate program. 1. Problems as nursing department in Medical School. 1) Many 4-year nursing baccalaureate programs are operating under the medical school as nursing department. So the academic development in nursing department is unprogressive and is not approved as unique discipline. 2) The operating system between nursing and medical department are different even though they are in the same school. 3) Inequality between nursing and medical department : In many case, the nursing professor can not attend administraion committees to discuss the medical school's operation because of many differences between nursing and medical organization. 4) Weakness of the leadership and the student activities in nursing student : The nursing student involvement is usually passive because of the difference of curriculum, less number than medical students and the difference between 4-year and 6-year education program. 5) There is the obscurity of the relationship between department of nursing and other departments in whole university. 2. Problems in nursing itself 1) We need to reconstruct nursing discipline. We must change from the disease centered model to health centered model and life cycle centered model so that we can be distinguished from medicine. We also must change from hospital centered nursing to all population centered nursing, 2) The improvement of curriculum ; When the independent framework of nursing discipline become established, we need to improve the curriculum. 3) The education of clinical practice ; Most nursing school programs are divided into professors who are lecturing the theory and clinical teachers who are teaching the nursing technique in the clinic. So, what is needed in nursing discipline is that the professors have a dual position. In America, The professor is required to be a clinical specialist and to have his or her clinic so that the professor become a good role model, teach the clinical practice effectively, and give the student the practice field. 4) To extend fields of nursing : At first, the school nurse must become the school health educator, a real teacher. The nurse must establish and operate a childern's wellbeing center or nursery school, a disabled people's house or senile's wellbeing center, a mental health center, and a health promotion clinic for healthy people. 5) The name 'nursing department' need to be considered. When the focus is to be changed from the disease model to health improvement model, we take into consideration change 'nursing college', 'nursing department' and 'nursing profession' to 'health science college' or 'health wellbeing college'. 6) We must have highly qualified academic students. Each Nursing educational faculties must have the high qualified students through the development of nursing educational program and the increment of scholarship. The Korean Nurses Association and The Korean Clinical Nurses Association need to make an endeavor for the improvement of work condition and payment of clinical nurses of hospitals who consist of 70% of all nursing manpower. 3. Improvement Strategy 1) All nursing educational program must be changed 4-year program gradually. 2) Nursing department need to try to become nursing college. 3) We need to study many researches for improvement of the problem in nursing discipline and nursing education. We need more interdisciplinary researches, and we need to be granted for that research. 4) We need to have many seminars and workshops thoughout the whole country to expand a sense of nursing education. 5) Drawing up a policies plan for the nursing educational improvement : The Korean Nurses Association, The Korean Academic Nursing Association, Korea Nursing College and department President's Committee, and Korea Academic Society of Nursing Education must try for the development of nursing educational improvement and ask for government frame the policy to develop nursing education.

In this study we investigated fecundity and survivorship of four staple Korean freshwater cladocerans for their whole life to develop a new standard method used for ecological risk assessment of pesticide. The tested Korean freshwater cladocerans were Daphnia obtusa, Daphnia sp., Moina macrocopa and Simocephalus vetulus. In addition, standard test species, Daphnia magna endorsed formally by the major international organizations was tested together in order to compare with the reproductive characteristics of Korean cladocerans. A total of 358 young was produced by D. magna, whereas, 297 young was reduced by Daphnia sp. throughout the entire life. The average life span of Daphnia magna was 50 days much longer than any other Korean species. Nevertheless all of the Korean water flea tested showed good fecundity, produced over 60 young for 21 days as the validation criterion for reproduction toxicity test in Ecological Effects Test Guidelines published by USEPA. Especially Moina macrocopa produced their first brood in 4 days. Therefore 10 day reproduction test with Moina macrocopa may be an alternative good method to save cost and time to elucidating the effects of hazardous substances on the reproduction of aquatic invertebrates.
