The routine entomological investigations were carried out in the areas of Kaejeon-Myon, OkkuGun, Cholla Pukdo province in 1964 and Sinchang-Myon, Asan Gun, Chungchong Namdo province in 1965, for the better understanding of the behavior of the anpheline mosquitoes especially of the population density , resting , feedign, and breeding habits. The results are as follows : 1. During the investigation , three species of anopheline mosquitoes were recorded ; Anopheles sinensis Wiedmann 1825, A, sineroides Yamada 1935, and A. yatsushiroensis Miyazaki 1951. A . yatsushiroensis Myiyasaki 1951, so far only recorded in Japan, was recorded for the first time in Korea in 1964 ; the site was Kaejong Myon, Okku Gun, Cholla Pukdo province. 2. Anopheles mosquitoes begin to appear from the middle of April and disappear in October. The date of mosquitoes collected by resting place collection in cow shed are three weeks ahead to the night time cow biting collection. 3. Resting places of anopheline mosquitoes are mainly in cow shed and outdoors which provides high humidity and shadow. 4. The population density of a. sinensis sows a peak in late June and early July in cow shed and by cow biting collection respectively, and another small peak in late August and early September. 5, . the biting activity at night is throughout the night from dusk to dawn, sharply decreasing just before dawn. The peak period was different in each months, 2100-2200 hours in June, 2300-2400 in July , 0300-0400 in August , and 2300-2400 in September. 6. The minimum temperature required for the mosquito's biting activity is 15 $^{\circ}C$ and the optimum is between 24-$25^{\circ}C$ : over $25^{\circ}C$ the activity is decreased. 7.A , sinensis appeared to be zoophilic in Sinchang area but 13 times anthrophophilic in Kaejong area than the former. 8. the light attraction of a. sinensis is significantly low in middle June and early August. The parous rate of A. sinensis caught by cow biting collection appeared higher after midnight (2400-0300 hours) with no relation to the peak period of biting activity by month.

This study examined the menu management and utilization of cooking equipment at school foodservice operations in the Chonbuk area. Self-administered questionnaires were collected from a total of 193 school dietitians. Statistical data analysis was completed using the SPSS v. 11.5 program. The results are summarized as follows. Among the 193 schools, 58.5% were elementary schools and 41.5% were middle and high schools. Approximately 97% of the schools prepared meals in the conventional manner. Among the school, 68.4% had a menu cycle of 1${\sim}$2 weeks. The frequency of using convenience foods was significantly different between the elementary schools and middle and high schools(p<0.001). Approximately 45% of the dietitians responded that the most important details for menu planning were menu variety and consumer preference. However, 66.8% of the dietitians responded that a key problem for menu planning was limited and worn-out kitchen equipment. Although the cost of purchasing cooking equipment is high, most dietitians responded they have high needs for equipment in order to meet of the quantity demands of food production. In terms of utilized cooking equipment, most schools had mixers, vegetable cutters, choppers, dish washers, etc. Yet the amenities most often lacking were meat slicers, composting machines, ovens, and griddles. In utilizing the cooking equipment, there was no significant difference between the dietitians in the elementary(3.67) schools and those in the middle and high school foodservice systems(3.70); however, the utilization level was poor. Therefore, governmental regulatory agencies should review and finance support for purchasing cooking equipment. Finally, purchasing analysis was conducted regarding the dietitians' opinions on menu recipes and useful equipment.

The purpose of this study is to survey middle school students’s awareness of sexuality and relationships with the opposite sex. The students need to have at their disposal basic resources on sexuality education and an established and systematic curriculum. To achieve this result, questionaires were distributed to 640 students who were chosen randomly in three middle schools in Seung-ju Goon and Goo-rye Goon in Chonnam area, 573 questionaries were used for the final analysis. The results were as follows： In the area of awareness of sexuality, male students regarded sex more positively than female students. It also showed that 19.9% or male students and 17.6% of female students were not aware of their virginity. Male students said they felt sexual impulses most when they saw naked women, and secondly, by sex magazines. This indicates students are motivated mostly by outside influences. There is a considerable gap in the degree of sexual knowledge between male and female according to their school year and father’s family education level. However, little difference is seen according to student’s family circumstance, father’s education level. However, little difference is seen according to student’s family circumstance, father’s job, and student’s religion and vise versa. School restrictions were so severs that 48.2% of boys and 47.1% of girls said that schools paid little attention to their needs. The school restricted rather than permitted relationships with opposite sex. Most of the students revealed a dissatisfaction with the school sexuality education program. Because of confucianism, Korean society has a negative attitude towards sexual activity including sexual education in the schools. 56.8% of male students and 81.4% of females students wanted female teachers to be their sexuality education teachers or advisors rather than male teachers, and 44.8% of male students and 51.2% of females students wanted to receive sexuality education in their Home Economics classes. Materials for sexuality education were considered most effective through videos and audio-visuals. As a result, this survey showed that there appeared to be a great need for a sound, effective, and sensitive sexuality education curriculum in the middle schools for teenagers. It should be conducted in such a way that the teenagers will learn about their sexual needs, their gender differences, and understand and know how to conduct themselves in today’s society sexually.

This study examines the classification and typical characteristics of 148 owner shop houses existing in the historical city center of Cheongju. First, they can be classified into single-story, middle-story, and divided types according to the distribution of residential and commercial functions. The single-story(36) has 'ㅡ', 'ㄱ', and 'narrow and deep'-shaped arrangement, with stores on the front and houses on the rear. The middle-story second floor(89) is divided into a first-story store and a second-story house, and the third floor(23) has different functions for each floor, but more than half of them have houses on the second and third floors. Among the total, there are also 16 cases in which the division type is taken with different construction times and structures. Second, in the position of the stairs connected to the upper floor among the middle-floor types(112), the outer stair type(52) to separate from the living space while making the most of the stores on the first floor accounts for 47%, but the biggest feature is that the inner staircase type(34) with privacy reaches 30%. The rear stair room type(26) entering through alleyways or private yards is also 23%. Third, the front pillar spacing varies from 1bay to 4bay in appearance, but the 2bay type on the 2nd floor and the 1bay type on the 3rd floor occupy the largest proportion. This exterior type is a characteristic of a owner shop house that can measure the range of personal ownership. Despite the conflicting functions of stores and houses, 35~40% of the cases are in which the opening positions of the upper and lower floors are unified.

Peptic ulcer disease is a gastrointestinal disorder caused by Helicobacter pylori infection and the use of nonsteroid anti-inflammatory drugs. While many studies have been conducted to find the risk factors of peptic ulcers, there are no studies on the suggestion of peptic ulcer prediction models for Koreans. Therefore, the purpose of this study is to implement peptic ulcer prediction model using machine learning based on demographic information, obesity information, blood information, and nutritional information for middle-aged and elderly people. For model building, wrapper-based variable selection method and naive Bayes algorithm were used. The classification accuracy of the female prediction model was the area under the receiver operating characteristics curve (AUC) of 0.712, and males showed an AUC of 0.674, which is lower than that of females. These results can be used for prediction and prevention of peptic ulcers in the middle and elderly people.
