Purpose: The purpose of this study was to identify the needs of health education in students, their parents and teachers in the elementary, middle and high schools and the current situation of health education class. Method: The subjects of this study were a total of 9450 persons including students, their parents and teachers from 279 schools throughout the country. They were selected through convenient sampling. Data were analyzed through x^(2)­test and ANOVA. Result: Students, their parents and teachers replied that 18 dimensions of health education class (DHEC) are necessary. The four DHEC - healthier life style, sex education, mental health and safety education - showed high educational needs in students, their parents, and teacher. High school students had higher educational need of 'symptom management for daily living' than elementary and middle school students. Students, their parents and teachers in elementary school had higher educational needs of 17 DHEC that those in middle and high school. The percentages of schools with health education class taught by health teachers were 99.2%, 75.5% and 66.0% respectively in elementary, middle and high schools. Health education was given mainly using physical education classes at elementary schools, and creative class hours at middle and high schools. In general, health education took 1-3 hours per week at elementary schools, and less than an hour at middle and high schools. Conclusion: Therefore, based on the results, systematic health education class should begin from elementary school to meet the need of health education in students, their parents and teachers, and further study should be made on the number of hours required and the amount of contents of 18 DHEC.

정보화정책에 있어 정부부처간 이익추구행태에 관한 연구 : 국가지리정보체계(NGIS)구축사업을 중심으로

이희선,윤상오 한양대학교 사회과학대학 1999 社會科學論叢 Vol.18 No.-

In the public policy-making process, as rational individual does, Government Ministries pursue self-interests. It is natural feature because they participate and interact as rational actors in the policy-making process. In the informatization policy-making process, many ministry participates and interacts for their self-interest maximization. Therefore, informatization policy-making process is a field of competition and battle for self-interests among the government ministries. In this study, using the public choice theory perspective, we inspect the cause of this situation, the result of it, and policy alternative to cure it. For the purpose of it, we examine the representative case of informatizstion policy. That is National Geographic Information System(NGIS) Public choice theory identifies the cause of self-interest behaviors of government ministries in the perspective of rational choice and rational actor. This perspective regards public actors' self-interest maximization tendency as a natural one. In the NGIS policy-making process, the results of it are budgeting loss, conflict among ministries, delay of project, overlap of project, absent of coordination and cooperation, and finally failure of policy. To overcome these problems, various devices are needed. First of all, we have to understand the causes of self-interest behaviors among governmental ministries. It is natural tendency for them to pursue self-interest maximization. Second, we have to establish the institutional device to introduce and induce cooperation and coordination among government ministries for the success of public policy. Third, using the strict evaluation of public policy, we have to identify the cause of result and performance and apply positive and negative compensation to government ministries in the bases of evaluation.

The purpose of this study was to estimate the possibility of practical application of TiN ion-plating method on orthodontic appliances. TiN was coated on the surface of orthodontic stainless steel roll band by means of ion-plating method, and colorimetric properties of its obtained TiN film were investigated by using color analyzer. Also its corrosion and discoloration properties were compared with those of non ion-plated stainless steel roll band by using immersion test, which was done in 1N HCI solution for 10 days. Both weight changes and surface corrosion appearances of specimens for each day were respectively investigated by using electronic weighing machine and SEM(Scanning Electron Microscope). The discoloration degress of TiN-coated specimens immersed in 1N HCI solution were investigated by using color analyzer and then judged by N.B.S.(National Bureau of Standard) Unit. The results of this study were summarized as follows. ㆍTiN ion-plated films showed the hue of 5Y, the value of 7, and the chroma of 3 by Munsell notations. ㆍThe weight losses and surface changes of TiN ion-plated specimens immersed in 1N HCI solution were less than those of non ion-plated specimens. It was shown, therefore, that the corrosion resistance was significantly improved by TiN ion-plating. ㆍThe discoloration degrees of non ion-plated specimens were too significant to be examined by color analyzer, while those of TiN ion-plated specimens were slight when judged by N.B.S. Unit. It was also apparent, therefore, that the anti-doscoloration property was significantly improved by TiN ion-plating.

권오용,윤희주,한수자 충남대학교 자연과학연구소 1987 忠南科學硏究誌 Vol.14 No.2

This study demonstrates the effects of four detergents and three on the activity change of phospholipase C which is prepared from the cultural broth of Bacillus cereus. This assay of phospholipase C activity was carried out with phosphatidylcholine micelles which were mixed with the detergents and sterols, with increase a molar ratio of these compounds to phosphatidylcholine. Phospholipase C was highly activated at 0.5 molar ratio of Tween 80-mixed micelles. In the case of Triton X-100, it was activated at higher molar ratio indicated 1.0. Sodium dodecyl sulfate was more effective than that of the other detergents at lower molar ratio. However sodium deoxycholate-mixed micelles increased the activity more 7 times than that of the control group. This maximum activation was occurred at 2.5 molar ratio and the turbidity was gradually decreased. Cholesterol and ergosterol increased the activity until molar ratio reached up to 0.9. But the activity was higher at 0.3 molar ratio for stigmasterol. Consequently, it was indicated that phospholipase C was activated with the supplement of detergents until the mixed micelles made a number of small and spherical shape.

This study was conducted to examine the effects of Jeot-kal and chitosan on the physicochemical characteristics and hardness during onion Kimchi fermentation. The onion Kimchi was stored at 4±1℃, for 42 days. The study results were as follows. The pH of control onion Kimchi and the experimental groups was in the range 5.30~5.80. The pH of the experimental groups slowly decreased during the fermentation. The total acidity of the four kinds of onion Kimchi was increased. The reducing sugar content was maximized at 4 days of fermentation, after which it decreased gradually as the fermentation processed. The ascorbic acid content of control onion Kimchi and the experimental groups was increased rapidly at 21 days and then decreased. The hardness of onion Kimchi measured instrumentally was higher in onion Kimchi treated with the salt-fermented Toha jeot juice than in control onion Kimchi.

The Asynchornous transfer mode (ATM) can be efficiently used to transport apcket data services. The switching system will support voice and packet data service simultaneously from end to end applications. To guarantee the quality of service (QoS) of the offered services, a source rate to send packet data is needed to control the network overload condition. Most existing control algorithms are shown to provide the threshold-based feedback control technique. However, real-time voice calls can be dynamically connected and released during data services in the network. If the feedback control information delays, a quality of the serviced voice can be degraded due to a time delay between the source and the destination in the high speed link. An adaptive algorithm based on the optimal least mean square error technique is presented for the predictive feedback control techinique. This algorithm is used to attempt predicting a future buffer size from weight(slope) adaptation of unknown functions, which are used for feedback control. In this paper, we have presented simulation results, which are related to the effective use of the algorithm.
