The purpose of this study was to investigate the characteristics of TMJ sounds by computerized sound power-spectrum analyser(SONOPAK, Bioresearch Inc., U.S.A.). TMJ sounds were recorded and anaylsed in the 87 patients wit TMJ noises by SONOPAK. The followings are the criteria of TMJ sound analysis. 1. It is possible to record the location of the TMJ sound in relation to the opening/closing cycle of mouth. 2. It is possible to record amplitude of sound(loudness) and frequency of sound (Hz) 3. Clicks display a narrow band of sound within the 0-300 Hz range. The peak frequency generally occurs between 50-150 Hz. And crepitus appear as a wide band of sound, occuring from 0-1300Hz. The data obtained from quantitative TMJ sound analysis give lots of information, but further researches are needed.

Members of this family Sciomyzidae are known as marsh flies and snail-killing flies because most of the known larvae are obligate predators of Mollusca, especially freshwater and terrestrial Gastropoda. Most species are found in the shallow ephemeral aquatic habitats with rich organic substrates, such as the hard-water streams, small ponds and lakes in mountain valleys. To date, a total of 8 marsh fly species in 4 genera have been known in Korea. During a taxonomic survey of the family Sciomyzidae in Korea, the authors have found the genus Ditaeniella Sack, 1939; thus, it was discovered for the first time in Korea. This genus can be distinguished by the other related taxa with hairs over much of the mesopleuri, hairs on the prosternum and one orbital seta. In addition, the nominate species, Ditaeniella grisescens Meigen, 1830 was also firstly recoded in the Korean fauna.

The subgenus Idioglochina Alexander, 1921 belongs to the genus Dicranomyia Stephen, 1829 and has a special habitat unlike other congeners. The larval stage inhabits marine algae near the intertidal zones. The most distinctive characters are found in the antennae with inner face of flagellar segments extended to produce a serrate form. A total of 30 species of the subgenus Idioglochina are recorded with the distribution is restricted to the Pacific and Indian Ocean regions. In this study, the subgenus and its species D. (I.) tokara (Nobuchi, 1955) are newly added to the Korean fauna. This species was previously recorded in Japan as an endemic species, but it was collected from Jeju Island. A redescription, period of activity, habitat information, and photographs of diagnostic characters of the species are provided. The female ovipositor is photographed for the first time.

The purpose of this survey was to investigate the status of dietitians' food service management in the elementary school lunch program. 386 dietitians in Kyungsangnamdo and Ulsan that participated in this survey, 350 dietitians were selected for analysis. The main results of this study are as follows. The most important item they consider was nutrition(42.5%), preferences(37.8%), budget(17.0%) in the menu planning. The standardized recipe was used in 92.8% of school dietitians. It turns out that 90% of them survey the price once per month, while twice per month for the cases having much more studnets or having longer career record. 70.8% use the computer program(Lunch) which was developed at Kyungnam, its use increases as longer as they have career record. 'Error occur' 75.7%, 'not knowing how to use' 13.6%, 'familiar with manual work' 7.8%, 'no computer' 2.9%, that's why they don't use the program. Food check up was done 82.5%. Amount of food after lunch was measured 'always' 67.6%, 'often' 30.0%, 'never' 2.4% and 'mostly by eye measure' 59.3%', 'always by scale' 22.7%, 'always by eye measure' 18.8%.

Purpose: The aim of this study was to identify the contraceptive knowledge, self-efficacy according to the career tract of high school female students. Methods: This study used a cross-sectional, correlational design using an exploratory survey methodology through self-reported questionnaires. The questionnaires were administered to 369 high school female students using a convenience sampling. Results: In the experience of sexual behaviors(grasping hand, hugging, petting, deep petting, sexual intercourse), technical female high school students showed more experiences than female high school students. In the contraceptive knowledge, the score of high school students' contraceptive knowledge was higher than technical female high school students. In the contraceptive self-efficacy, there was not a significant difference between the technical female high school students and female high school students. In the female high school students, there were significant differences in the contraceptive knowledge according to grade, academic record, sex education experience and there were significant differences in the contraceptive self-efficacy according to grade, academic record, parents' attitude about acquaintance of the opposite sex. In the technical female high school students, there was not significant difference in the contraceptive knowledge according to demographic, sexual behavior, and contraceptive related characteristics but there were significant differences in the contraceptive self-efficacy according to grade, parents' attitude about acquaintance of the opposite sex, contraceptive education experience at school. There was positive relationship between contraceptive knowledge and contraceptive self-efficacy. Conclusion: Further research is needed to identify the prevalence rate of contraceptive attitude using more reliable variables. A sex education program should be developed for promoting use of contraceptive measure and formation of positive contraceptive attitude among high school female students.

Purpose: This study was to identify the types and characteristics of health problems of middle school students in Gangwondo. Methods: The subjects of the study were 11 middle schools from 47 schools with nurse teachers in Gangwondo. The anecdotal records of the school health clinics were collected from March to December in 1998 with the agreement of nurse teachers of the schools. Results: 71.0% of the middle students visited the school health care clinics once or more than once. The mean frequency of health problems was 2.03 times per one year. The rate of health problems did not show any statistical differences by sex, school location, age, the day of the week and weather. However, there were statistical differences of the rate by month. The highest rate was showed in September, followed by June and April (F=2.52, p=0.01). Health problems were classified into 11 types. Gastrointestinal illness showed the largest proportion (60.6%). The oral illness showed statistical differences among the location of school, between municipal and rural area (t=-2.97, p=0.016). There were 411 types of signs and symptoms recorded. Among them, headache was showed the highest proportion with 2,122 cases (11.2%). Conclusion : The incidence rate of health problems was higher than that of earlier studies. It showed that the incidence rates and the types of diseasps in middle school students were different by school locations, characteristics of students, and months. To improve the qualities of primary cares in school health services, the reformed and unified anecdotal record system and the standardized guidelines for primary care are necessary.
