In Korea, fluoride was first introduced into the drinking water of residents of Jinhae, Kyung Nam in 1951 for the prevention of dental caries. Ever since, growing numbers of communities favor fluoridation. The mechanism of F prevention of tooth decay is well known: fluoride ions substitute for hydroxyl ions in hydroxyapatite of hard tissues, which result in crystal perfection, with consequent reduction in dental caries. Soluble fluorides such as sodium fluoride are almost completely absorbed from the gastrointestinal tract. However, the presence of divalent or trivalent cations such as aluminum, magnesium, and calcium that can complex with F can reduce the degree of absorption. In U.S.A., over 7000 communities are now adding F to their drinking water. However, some portion of population oppose fluoridation, voicing both concern about the safety of fluoridation as well as for personal choice. Thus, This paper reviews the interaction of fluoride and cations as well as fluoride and suggests possible problems associated with fluoridation, a controversial issue.

증류수에 첨가된 불소에 의한 알루미늄 주방용기로부터의 알루미늄 용출에 관한 연구

Fluorine (F), the lightest member of the halogen group, is the most electronegative of all the elements, which means that it is present as fluoride ion (F-). Fluoride is widely distributed in nature, but it also been added into the municipal drinking water for the prevention of dental caries. In Korea, fluoride was first introduced into the drinking water of residents of Jinhae in 1981. However, several studies reported that 1ppm fluoride in water caused various extent of the leaching of aluminum from cooking utensils, ranging from 5 % to a thousand-fold increase, although other studies reported no increase in the extent of aluminum. Here, we report, for the first time in Korea, that the extent of the leaching aluminum increased as boiling time increased, pH of triple distilled water decreased and 1 ppm fluoride is added into the triple distilled water. Especially, the extent of the leaching of aluminum in acidic water was above the maximum contaminant level of aluminum in finished drinking water, 0.2 ppm. This leaching of aluminum was further increased by 1 ppm Fluoride addition. However, the influence of aluminum leached from cooking utensils on bioavailability and potential toxicity needs further investigation.

국문초록누락 The purpose of present research is to offer the survey data on the expertise, the understanding of children's physical development and their physical activities, and the educational condition, of the instructors who teach physical education (PE) to young children in various educational institutions and other child-related facilities. 207 subjects of survey in a written form performed in this research include instructors belonging to 15 specialized institutions for teaching PE for young children located in Seoul and in Gyeonggi-do. 16 subjects of survey in an oral form (i.e., interviews) include 15 chiefs managing the specialized institutions for teaching PE for young children located in Seoul and Gyeonggi-do. The findings in this research are as follows: First, inspecting the 'expertise' of the instructors who teach PE to young children reveals that majority of the surveyed instructors majored in PE in institutions for higher education; only the half of the surveyed instructors have the qualifying license. Second, the survey on the understanding of children's physical development and their physical activities reveals that the surveyed instructors are well aware of activity progression with respect to children's physical development and teach appropriate physical activities accordingly. Third, the survey on educational conditions reveals that instructional curricula consist mainly of the area in self-testing through employing integrated apparatus while children prefer various games, It is also shown that the surveyed instructors teach proper basis physical activities with respect to children's physical development - easy to difficult activities according to children's age, and that the instructors' preferred apparatuses are mat and uni-bars for children's age 3, 4 and 5.

초·중등 과학 교과서의 삽화에 나타난 성별 편중성에 관한 연구

Textbooks are an intergral part of instruction. If those textbooks lack images of women engaged in science activities, students may view science as an arena exclusively for men, especially students. Therefore a balanced and comprehensive portrayal of women in science textbooks is important. In this research, illustration of elementary and secondary school science textbooks are analyzed to determine whether the depiction of males and females was quantitatively and qualatatively gender equitable or not. One Japanese secondary science textbooks was in favor of male. Resolving the inequity of the science textbooks will be a great role to draw female students to the science and technology field. Therefore the research and development of textbooks which appeal to female students are quite necessary.

다이옥신의 발생, 영향 및 오염현황

安惠媛 水原大學校 1997 論文集 Vol.15 No.-

In Korea, high concentration of dioxin(approximately 5ng/㎥)was detected in emissions from municipal waste incinerators. Ever since, residents in the vicinity of municipal waste incinerator facility fear that the exposure to dioxin could cause toxicity such as cancer. Thus, in worst cases, the facility had to stop due to the strong objection of the residents. However, dioxin can be measured everywhere in biological tissues as well as the environment. In general, dioxin level in air or water is low, whereas that in biological tissues(especially fat and milk) is high because of bioaccumulation in food chain. Concern about dioxin toxicity has been heightened since recent studies show that noncancer adverse health effects of dioxin occur at very low concentration near background level. Thus, this paper reviews many aspects of dioxin including source, human exposure, mechanism of action, toxicity and contamination level in Korea.

The purpose of this study was to measure the knowledge, aptitude, behavior in sex for College students in order to provide basic sex education information, more proper knowledge and healthier culture in sex. For this study, the questionnaires were given to 100 students who were 52 males and 48 females in three universities in Seoul and collected during from november 25 to november 30, 1996. These results were analyzed satistically by means of frequency, percentage, t-test, ANOVA, and multiple regression analysis. The results of this analysis are as follows : 1.The universal trend of knowledge , attitude, behavior of college students in sex. 1) The level of knowledge about male related to sex was relatively high and male get higher score than female. On the other hand, the level about female related to sex was relatively low. 2) In attitude toward sex, male was more open-hearted than female. Especially, about some questions related to attitude of male's sexual intercourse, male related to sex was more open hearted. 3) On behavior in sex, generally, male experienced relatively often. Specially, male experienced masturbation and sex intercourse comparatively frequent than female. 2.The analysis ragarding variables of dynamic statistics of population. The level of sexual knowledge of the Buddhist group was relatively high than the Christian group and the group had not any religion. The buddhist groups and the group had not any religion were more open-hearted than the Roman Catholic group in the altitude related to sex. The group whose mother graduated college was more frank than the group whose mother graduated high school or middle school in sexual behavior. The group whose member engaged to marry experienced sexual behavior frequently. 3.The results regarding knowledge, attitude, behavior according to variables of dynamic statistics of population. As sexual attitude is more frank, age is older, and the relationship is more advanced, respondents experienced sexual behavior frequently. In religion, the Christian group experienced sexual behaviors realtively rare than the group had not any religion. Male have many sexual experiences than female. According to these results of this study, I am going to propose some prefactories. 1.In order to provide proper sexual knowledge, some lessons connected wish sex must be set up for college students and many counsel work is needed for the students who had sexual problems. 2.Some studies about sex education program are needed in chain of marriage preparation program.
