This study was performed to confirm the actual temperature rise on the surface of Buchanan plugger by evaluating the temperature rise on the surface of it, the peak temperature of pluggers of various size using thermocouple. The heat carrier system 'System B Heatsource' (Model 1005, Analytic Technologies, USA) and the Buchanan pluggers of F, FM, M and ML sizes are used for this study. The temperature was set to 200 which Dr. Buchanan's "Continuous wave of condensation" technique recommended on digital display and the power level on it was set to 10. The touch mode was used. Five thermocouples were placed in direct contact with the surface of each size of Buchanan's pluggers at 1 ㎜ increments from the tip to the 4 ㎜ length of shank. Each thermocouple was secured with cyanoacrylate adhesive and orthodontic resin block. The two wire leads of each thermocouple were connected to the appropriate channels of Data Logger. This was configured to simultaneously record input from the five thermocouples. The heat control spring was touched for 1, 2, 3, 4 and 5 seconds, and the temperature rise on the surface of the pluggers were measured at 1 sec intervals for more than 5 seconds with an accuracy of 0.01. Ten trials was determined for each plugger. The average of temperature rise and standard deviation was calculated for each size of plugger. The data were statistically analyzed by one-way ANOVA to determine their significance. The results as follows. 1. The position at which the temperature peaked was approximately at 1∼2㎜ far from the tip of Buchanan plugger (p<0.01). 2. The peak temperature was 215.25±2.28℃ in F plugger, 185.94±2.19℃ in FM plugger, 169.51±9.12℃ in M plugger, and 160.79±1.27℃ in ML plugger and the peak temperature was highest in F type and followed by, in descending order, FM type, M type. ML type showed the lowest peak temperature (p<0.01). This results suggest that the actual temperature on the surface of the pluggers does not correlate well with the temperature set on digital display. Heat concentrates around the tip. The larger plugger reveals lower temperature rise relatively.

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.

Themal and catalytic pyrolysis of plastics have been carried out. The thermogravimatric analyzer(TGA) and batch type laboratory scale catalytic reactor were used as experimental rigs. Pure or waste plastic samples(HDPE, PP,PS, ABS), collected from domestic industry were used for the experiment. The powder of silica alumina(50g) was used as catalyst for pyrolysis. The experimental results showed that the decomposition temperature was increased with an increase of heating rate, because of time lag associated with heating of plastic samples. It was also found that the maximum decomposition rate and decomposition temperature of HDPE are much higher than those of other samples.

The coast area of our country has various tourist attracting factors of its own such as plenty of islands, uncontaminated waters and so on. Nevertheless, sea tourism and leisure facilities have not been developed enough since the national tourist/leisure policies have mainly been focused on the land tourism so far. Recently, the lake and sea areas are becoming more and more popular to people for spending their leisure times, and they, especially the young generations, are eagerly searching for some good ocean spots to enjoy the dynamic maritime sports. The marina resort of Choongmu Donam tourist complex, which is the first ocean resort of our county, is currently equipped with a pier exclusively for yachts including associated maritime leisure facilities and amusement park, and many other relevant sports facilities are either under construction or planned to be formed soon. The design and production of yacht does not awake people's interests yet in our country, and as a result, is very inactive, even though the yacht itself plays the key role among many ocean resort facilities. The future prospect of yacht industry, however, seems to be very bright in the long run, and it is expected to take a major portions of maritime leisure industry. Consequently, the design of economic, visually affable, and environmentally adaptive yacht, which is suitable for our country's circumstances, is very significant. The two key components of good design of yachts are: the mechanical/dynamic stability aspect based on the engineering technology, and the visual appearance from the esthetic point of view, and thus the close co-work and cooperation between engineers and designers are indispensable in order to maximize the research efficiency. In this study, we plan to work on the first design phase of environmentally and visually adaptive yacht, taking the cost effectiveness and the safety factors into account as well.
