Purpose: This study was done to investigate sexual problem behaviors of high school students in one province, North Cholla. Method: The participants in this research were 951 high school students, grades 1, 2 and 3, chosen at random in big cities, small towns and rural areas of North Cholla Province. Result: The routes for sexual knowledge acquisition were through a peer group or an older member(35.8%), internet(29.8%), classes and the teacher at school(18.8%), multimedia(8.4%) and parents (7.2%). The percentages for domains of sexual problem behaviors were masturbation 36.7%, sexual impulse 35.6%, voyeurism 12.6%, sexual violence 9.6%, transvestism 4.1%, prostitution 3.5%, exhibitionism 3.1%, and pregnancy of a female student 0.6%. Sexual problem behaviors experienced by 30% or more of the students were reported as the experience of the desire to embrace, the desire to kiss, the desire to touch a friend's body of the opposite sex, masturbation and the desire to sleep with a friend of the opposite sex. The biggest sexual problem behaviors for the students were sexual impulses toward friends of the opposite sex and masturbation. These experience rates were higher for boys than for girls(p<.05), higher vocationally than academicly(p<.05), and higher in the largest cities than smaller cities and rural area(p<.05). Conclusion: These findings suggest that systematic programs that focus on a problem solution method should be developed for sexual problem behavior prevention.

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.

The source of wayside noise for the train are the aerodynamic noise, wheel/rail noise, and power unit noise. The major source of railway noise is the wheel/rail noise caused by the interaction between the wheels and rails. The Structure borne noise is mainly a low frequency problem. The train noise and vibration nearby the elevated railway make one specific issue. In this paper, the train noise and structure borne noise by train are measured. From the results, we investigated the effect on the sound absorption tunnel for elevated railway.

This study attempts to explore and explain major socieconomic factors which determine the extent of rural consumers' external search behavior in cases of two product categories: electric appliances and clothing. For the purpose of this study, interviews were conducted with 201 home managers in four rural towns(Hwasun, Haenam, Naju, and Bulkyo) of South Cholla Province. On the whole, the hypotheses that socioeconomic status, age and the characteristics of region of rural consumers make significant differences in their shopping motivation and the extent of external search are generally supported in case of clothing. No substantial differences are found in case of electric appliances. This study suggests that the effective purchasing system and the providing of informative consumer information would be needed to rural consumers for their extensive search. It also suggests that psychological aspects and situational variables in addition to socioeconomic aspects presumably contribute to our understanding of search behavior.

Tree-ring dating can be used to date scientifically prehistoric timbers, historical buildings or woodcrafts. It can give a calendar year to each tree ing and produces the felling dates of logs or wood panels. In this study, we applied tree-ring dating to three rice chests, whose dates of manufacturing are unknown. According to the shape of frame, we assumed that they should be made in Cholla Province. The last rings of the woods of three rice chests were dated A.D. 1830, A.D. 1870 and A.D. 1901, respectively. Tree-ring patterns indicated that two of them were collected from Kangwon province.

This paper is studied in order to examine eight provinces as Agricultural zone in the early Chosun-Dynasty. The research method of this study depends on discriminant analysis. The research data is obtained from geography of Sejong sillok. In this approach, we believe the possibility of more scientific analysis of agricultural zone. So all cross-sectional data of this period were analysed by means of the discriminant analysis method. In the discriminant analysis of the eight provinces, 54.6% of the country were discriminated. In the territorial map, Kyongsang and Cholla were crossly adjoined and Chungcheong was located in the middle of them. While, Kyonggky and Hwanghae were adjoined in the center, and Pyongan and Hamgil were crossly adjoined, too. And Kangwon was located in the middle of them. Consequently their regional distribution varied widely and the agriculture of this period had considerable regional gaps.

This thesis is written to point out the fact that story-teller has to be also appointed to intangible cultural treasure. For this, I compared the birth tales of king keum-wha and al-yeung with ghene-gid-dang dangshin(house-ghost) Bonpuri in Che-ju Island and the place name yeun-gi tale in Yong-ghe-won, Whan-ju gun, Cholla-buk-do. And, I examined that the latter oral narratives are very useful to interpret the meaning of the former documents. Besides, using the In-ju tale(人柱傳說), I clarified that Oral narratives reflect the Korean people's consciousness structure. Through all these, I elucidate oral narratives have the value as cultural treasure. Consequently, I maintain the professional story-tellers have to be appointed to intangible cultural treasure.

Total area of bamboo groves in Korea which is limited to $37^{\circ}$ north latitude, i.e., to southern part of Chungchung-nam-do Province and Kangwon-do Province, is 3,235ha., but this country must import about 3,000 metric ton's bamboo culms from Japan every year. It may be true that the country is not so fit for economical cultivation of bamboo groves from the view point of climatic condition, but the author believes that self-sufficiency in bamboo is not impossible if some scientific method for improving bamboo groves is introduced to our primitive groves. Keeping this point in his mind the auther tried to study on the bamboo groves in the country, and as the first step set about to investigate the actual state of twenty good bamboo groves located in Cholla-nam-do Province from March, 1961 to January, 1962. This is a report on some characters of bamboo culms and growing stock with samples collected in the present investigation. 1) Numbers of bamboo culm per 0.1ha. are 1,183 in average, 1,840 in maximum and 87.5 in minimum before harvesting. 2) According to owners' saying, 1960 was such an off-year that they could hardly see any yearling bamboos in groves, but in 1961 very many new bamboos are produced as follows: the proportion of the number of yearling bamboos produced this year to that of mature bamboos (over 2 years old) is 58.7% in average; the highest 110.5% and the lowest 16.8%. 3) the average diameter of culms at eye height is 6.5cm, but the biggest diameter comes to 11.2 cm, and the average diameters of yearling and mature bamboos are 6.5cm and 6.6cm respectively. 4) Internode length records 29.4 cm in average, the shortest 21.3 cm and the longest 38.4 cm. Average internode lengths of new culms and mature culms are 27.6 cm and 29.4 cm respectively. This shows that the internode length of new culms is in the decrease to that of maturer's. 5) Through this investigation, it was found that internode length is in the influence of the exposure and density of bamboo groves, i. e., the more the dencity of bamboo groves is and the more the exposure nears the north-east, the longer the internode length becomes (see Table 7 and 8). 6) In the growing stock of bamboo groves, bundles per 0.1ha. amount to 271 sok (unit of bundle) in total average, 445 sok in maximum and 126 sok in minimum. 7) Among twenty typical bamboo groves, chosen in each County in Cholla-nam-do Province, only one passes perfectly by Veda's standard rule* prescribing the good bamboo grove, but the eight groves shown in Table 9 could be recommended as good ones in Cholla-nam-do Province, because the auther believes that those groves may be improved better, if we pay more attention to the management of them. 8) Considering that they have managed their groves carelessly and primitively, and that unfortunately their groves must have faced almost on clear felling over the entire area at the time of the Korean War, we can surely expect much more increments in bamboo groves, if we introduce some scientific methods in managing their groves.

The purpose of this study was 10 examine whether or not the dental- health education experiences of elementary school teachers have any influence on their oral-health awareness and attitude. The subjects in this study were 414 selected teachers from Seoul and North Cholla province. The instrument used by Lee Heung-su was modified into self- reporting questionnaire, and the schools where the subjects were working were visited to conduct a survey for 28 days from September 15 to October 13, 2000. For data analysis, SPSS was employed, and chi-squre, t-test and ANOVA were implemented. The findings of this study could be listed as below: 1. 184(44.4%) out of the techers investigated had ever been educated in dental health, and 230 teachers(55.6%) hadn't. 47% replied they hadn't received oral-health education for the lack of education opportunities. 2. In regard to dental-health awareness and attitude. the presence or absence of dental-health education experiences didn't make any difference to their daily toothbrushing frequency(p>0.05). The use of fluorine was significantly different between the groups(p<0.01), as 42.9% of the teachers with dental-health education experiences and 63.9% of the others with no such a experience didn't use that, 45.7% of the former group and 29.1 % of the latter accurately knew how to brush teeth, and the difference between the two was significant (p<0.01). 3. Concerning student-related dental-health awareness and attitude, the dental-health education experiences make 45.7% of the educated group and 31.7% of the uneducated group agreed to the strong need for oral examination, and the gap between the two was significant(p<0.01). 90.8% of the former group gave counsel to students on dental health, and 77.2% of the latter didn't. The gap between the two was significant as well (p<0.01). 77.2% of the educated group and 41.3% of the uneducated group offered frequent dental-health education, and the difference between the two was significant (p<0.01). 4. Their awareness of the fluorine-based toothbrushing project differed significantly by region(p<0.05), as the teachers from North Cholla province recognized it better than those from Seoul. The female teachers provided more education regarding that project, and those who were older or had more teaching experiences were more aggressive in instructing that project(p<0.01). And the married teachers took more forward attitude than the unmarried (p<0.01). By school location, the teachers from Seoul showed more active attitude than those from North Cholla province(p<0.01), and the gap between the two was significant. As to cooperation, those who were older or had more teaching experience were more cooperative, and the married teachers joined forces better than the unmarried. The gap was significant (p<0.01). 5. Concerning the awareness and attitude of the fluorine-based toothbrushing project, the educated teachers took more aggressive attitude, and the difference between the two was significant(p<0.01). The above-mentioned findings suggested that the dental-health awareness and attitude of the elementary school teachers were under a lot of influence of their oral-health education experiences, and there is a need to develop and carry out education programs for teacher.
