  • 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 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 to investigate the confirmation and prevalence of porcine cytomegalovirus (PCMV) infection of pigs in Korea using enzyme-linked immunosorbent assay (ELISA). Four hundred-eighty one sera tested were collected from the areas of Kyonggi, Kangwon, Chungcheong, Cholla, Gyongsang and Cheju during the year of 1991 to 1997 except 1994. PCMV antigen, OF-1 strain, for ELISA, was prepared 19-PFT-F cell line originated from porcine fallopian tube. Positive control was used by sera made from the specific pathogen free piglets which were infected with OF-1 strain. Three hundred-sixty seven of 481 sera (76.3%) were positive against PCMV. Antibody titers of these seropositives were classified by 129 (26.8%) cases in more than 1 : 12,800, 77 (16.0%) in 1 : 6,400, 76 (15.8%) in 1 : 3,200, 44 (9.2%) in 1 : 1,600, and 41 (8.5%) in 1 : 800, respectively. Also, the seropositive pigs were divided by 87.4% (76/87) in older than 6 month-old, 73.9% (238/322) in 2~6-month old, and 73.6% (53/72) in less than 2-month old, respectively. Regional prevalence rate of PCMV infection in Korea showed 89.7% (70/78) in Chungchong, 79.8/% (83/104) in Cholla, 79.4% (143/180) in Kyonggi, 79.3% (42/53) in Gyongsang, 50% (15/30) in Kangwon, and 38.9% (14/36) in Cheju area, respectively. In the sera collected in 1991, seropositive rate was appeared as 90.2% (37/41). From 1992 to 1997 except 1994, the average infection rate to PCMV was 77.5%. Consequently, these results confirmed that PCMV in Korean piggeries was introduced at least before the year of 1991. More importantly, PCMV infection has been prevailing nation-wide in pig herds in Korea.

  • The damage by fruit-piercing moths in orchards, primarily on grapes cultivated on reclaimed hillsides in Koksung, Cholla Namdo, was surveyed during July to October, 1974. Moths collected at night, mostly with the aid of flash light, were then classified. Results are summairzed as follows; 1. In addition to the 14 species of fruit-piercing moths reported in Korea, 11 new species were collected lot the first time ia Korea. These include. Speiredonia retorta Clerck, Cocytodes coerulea Guenee, Metopta rectifasciata Menetries, Ophideres fullonica Linnaeus, Serrodes campana Guenee, Mythimna turca Linnaeus, Amphipyra livida Schiffermuller et Denis, Paralleia maturata Walker, Ophiusa tirhaca Cramer, Anomis mesogona Walker and Thyas dotata Fabricius. 2. The maximum emergence of moths in Koksung Orchard was from the 10th to the end of September. Only a few moths were observed befroe the begining of August or after October 10. 3. The number of moths flying to grape vines increased as the time advanced from sunset to midnight. Populations gradually decreased thereafter until 5:30 a. m., when only occasional moths were observed. 4. Average damage to grape fruits by these insects was virtually nil until August 10; with subsequent infestation rates of $1.0\%$ on August 15, $17.6\%$ on September 26, and $20.3%$ on October 4, respectively. 5. Fruits of less than 10 percent sugar content and higher than 6.2 acid value were free from damage by these moths, and those of higher sugar content and lower acid value to be more heavily attacked.
