The following results have been driven out from a survey of the actual conditions of the public libraries service in Korea, made through questionnaire in reference with the actual service for youth that are presently done by the foreign countries' libraries, in order to prepare a perfect and objective base in establishing a service activities of the public libraries in this country: (1) It was found that the public libraries' loarning hours during the week days which accords with the schooling hours of the schools are shown to 50 %. On Saturdays during Summer season seven libraries and during Winter season twelve libraries would close their loaning before 17 : 00 hours, and on Holidays and Sundays fifteen libraries are not doing their loarning. (2) The followings are the present status of the service activities for the youth by the public libraries: a. It was found that they do introduction activity (50 %) of newly published books as a service for inducing reading interestings of the youth, and except this it was found that others are on beginning. b. The service activities by the data for the visual and auditory sense are almost negelected. and the rate of doing such activity is shown to 9.74%. c. It has been found that little information service activity is for inducing the youth to the libraries. d. As a cooperative activity with the school's, a passive service activity to have pursuaded to visit the public libraries by each class, are mostly being done (27.27%). Some research meeting for solving all the matters between the school libraries are not held mostly.

By tracing albumin stabilizing activity an anti-inflammatory component, continentalic acid was isolated from ether-soluble acidic fraction of Aralia continentalis. Continenetalic acid in a concentration of 0.115mg/3ml gave 50% inhibition for heat denaturation of albumin. The protein stabilizing potency of it was approximately three and eleven times that of phenylbutazone and that of salicylic acid, respectively. The anti-inflammatory actions of it and its methylester were investigated employing carrageenin-induced edema in rat paw. Continentalic acid administered s. c. showed an activity of about three times of hydrocortisone. When administered p. o., it was still active, but its methylester was more active than phenylbutazone, suggesting the poor absorption of it in gastorointestinal tract. Its chemical structure was identified by chemical and spectral studies as (-) pimara 8(14), 15-diene-19-oic acid, which was already isolated from A. dordata, but not reported for its biological activity.

The purpose of this study is to examine factors causing the female adolescent sexual activity. 201 female adolescents participated in this study. Each participant was classified into the sexual activity experience or non-sexual activity experience group on the basis of survey. In total, 87 female adolescents have sexual activity experience, and 114 female adolescents have non-sexual activity experience. Analysis reported that sexual activity experience group was more positive on the adolescent sexual activity than non-sexual activity experience group. Also sexual activity experience group has more peers having sexual activity and pregnancy experience than non-sexual activity experience group. And, sexual activity experience group was more coping level and lower father social support than non-sexual activity experience group. Logistic regression analysis was conducted in order to determine the extent to which the attitude on the adolescent sexual activity, peer group's sexual experiences, social support, and coping factors affected on female adolescent sexual activity. As a results, peer's sexual activity and peer's pregnancy factors were significantly associated with it. Finally based on the results, the intervention strategies were suggested.

In order to know the defense mechanism of fish, bactericidal activity was examined into the sera of carp Cyprinus carpio, tilapia Oreochromis niloticus and flounder Paralichthys olivaseus. Each examined normal serum of fishes showed the bactericidal activity against avirulent Escherichia coli but it wasn't appeared against virulent Edwardsiella tarda. When the normal serum of each fish was treated with zymosan, it lost the bactericidal activity completely. After addition of EGTA into the normal serum of each fish, the sera of tilapia and flounder still exhibited the bactericidal activity but the serum of carp lost it. In the presence of specific antibody and complement, bactericidal activity of each antiserum was exhibited high level with in one hour incubation. On the other hand, heat inactivated antiserum showed bacteriostatic reaction. From the above results, although the activity of alternative or classical pathway of each fish complement is different, it is an important function in fish defense mechanism.

This article extracted feasible elements for an environmental education program from the 'Intelligent Life', an integrated subject of the 7th elementary school curriculum, and designed a program for second graders in the elementary school and applied it to them in order to examine how the students' environmental altitudes changed. In the controlled class, the instruction followed the lessons specified in the 7th national curriculum faithfully while for the experimental class 1, only the inquiry activity-based environmental education program was applied. Moreover, in experimental class 2, the inquiry activity-based environmental education program was implemented and wrap-up activity was performed as well with the products. To verify the program, questionnaires on the change of environmental altitudes were distributed and analyzed total three times in the pretest, posttest 1(right after the program), and posttest 2(30 days after the program). T-test was carried out with the SPSS 12 program to verify the effect of the applied program. To make up for the quantitative analysis, qualitative analysis was also conducted. The followings show the results gained after the program was implemented. First, This program showed a significant difference(p<.05) in the students' formation of environmental altitudes. Second, it was verified that the inquiry activity-based environmental education class that reorganized the second grade elementary students' 'Intelligent Life' subject had a more positive effect in the cultivation of environmental altitude than the class that followed the present curriculum as it was. It will be necessary to perform follow-up researches on the relativity between curricula for kindergarteners and lower grade elementary school students.

The susceptibilities of aldehyde dehydrogenase (AldDH) and alcohol dehydrogenase (ADH) to active oxygen generated by xanthine-xanthine oxidase (XOD) system were studied. Incubation of AldDH with 2$\times$10$^{-3}$ units of XOD for 30 min at $25^{\circ}C$ resulted in the decrease of enzyme activity to 30% and it was inactivated completely when incubated with 5$\times$10$^{-3}$ units of XOD. Whereas 70% of ADH activity was retained after exposure to 5$\times$10$^{-3}$ units of XOD for 30 min, 40% of ADH activity was retained after exposure to 5$\times$10$^{-2}$ unit of XOD for 30 min. This inhibition effect by the active oxygen was preventable by catalase and glutathione, but not by SOD. The rates of the NADPH-dependent oxygen consumption by the liver S-9 mixture and microsomes were also determined in this study. Rate of oxygen consumption is increased in the liver S-9 mix and microsomes from phenobarbital-treated rat, and it was consistent with increased lipid peroxidation. In the presense of ethanol as a substrate, the oxygen consumption rates were increased. It is reported that hepatic AldDH activity is depressed in alcoholic liver diseases, however there is few report that explains the reason of depressed AldDH activity. These results are supportive of the theory that the increase in hepatic ethanol oxidation through the induced ME activity after chronic ethanol feeding generate oxygen radical at elevated rates and it leads to the depression of AldDH activity.

It is necessry to develop and strengthen the activity of enzymic source which in low applied for maggerley brewing as an amylolytic and proteolytic starter, recently in this country the active and strong enzymic starter is required for the better brewing and to substitute another starch material for the present wheat flour. In this study, manufacturing method the strong enzymic source have been developed and established with use of raw wheat bran plus fungal strains of Rhizopus sp. and Aspergillus usamii the culture of starter. The results on experimental the activities of enzymic sources (stater) are as following ; 1. Method of making the enzymic source (starter) is to cultivate the strains of Asperguillus orzyae, Asp. kawachii, Asp usamii and Rhizopus sp. in the acid treated raw or heatboiled wheat bran. 2. The saccharogenic pwoer (S.P.) of enzymic source which consisted of raw bran plus fungi and cultured in it is generally stronger than those of heat-boiled bran plus fungi, the strongest power was shown in the culture of Rhizopus plus raw bran, and the next other is in mixture of Asp.usamii and Rhizopus on raw wheat bran. 3. The most strong alpha amylase activity was expressed in the plot of Asp.oryzae on heat-boiled wheat bran, the next was in the culture of Rhizopus nad Aspergillus usamii on raw wheatbran. 4. The most vigourous acidic proteinase activity was expressed in the micture of raw bran plus Asp. usamii and Rhizopus those were independentlu cu;tured before mixing for neutral proteinase activity, it was shown in the mixed culture of Asp. usamii and Rhizopus on raw wheat bran, the msot active alkaline proteinase activity of enzymic source was found in the plot of raw bran material. 5. For poly-preptidase activity in pH 6.5 it is found that the culture of Rhizopus and Asp.usamii on raw bran was most active among them of enzymic sources. 6. Generally, it is concluded that culture of fungi on acid treated raw wheat bran is stronger in its activity than those of heat boiled wheat bran, especially the culture of Rhizopus nad Asp.usamii on raw bran exhibited the most vigorous and non-polarized activity for all aspects, so it is considered to be most desirable enzymic stater in Korean Maggerley brewing and this would be able to substitute brewing material for the present wheat flour because of its strong and wide hand activity of amylolytic and proteolytic action.

The purpose of this study was to analyze the concept of physical activity. The method was based on the steps of concept analysis by Walker and Avant(1988). The result of this study were as follows； Upon the concept analysis, physical activity is defined as a series of bodily movements which is performed voluntarily by individual. The defining attributes of physical activity were a series of bodily movements, energy expenditure, goal-directedness, and self-control of the body. The antecedents of physical activity were neuromusculoskeletal function, cardiopulmonary function and cognitive function. And the consequences of physical activity were improvement of physical function, induction of fatigue, and need(physiopsychosocial) satisfaction. Further studies are needed to develop the concept of physical activity using the Hybrid model. In addition, considering personal characteristics it is important to study the facilitating factors of physical activity.
