Much attention has been focused on the Baekpoman area due to the archaeological achievements of the past, but studies on prehistoric times when villages began to form is insufficient, and the Bronze Age village landscape was examined in order to supplement this. In the area of Baekpo Bay, the natural geographical limit connected to the inland was culturally confirmed by the distribution density of dolmens, and the generality of the Bronze Age settlement was confirmed with the Hwangsan-ri settlement. Bunto Village in Hwangsan-ri represents a farming-based village in the Baekpo Bay area, and the residential group and the tomb group are located on the same hill, and it is composed of three individual residential groups, and the village landscape had attached buildings used as warehouses and storage facilities. In the area of Baekpo Bay, it spread in the Tamjin River basin and the Yeongsan River basin where Songgukri culture and dolmen culture were integrated, and the density distribution of the villages was considered to correspond to the distribution density of dolmens. In order to examine the landscape of village distribution, the classification of Sochon-Jungchon-Daechon was applied, and it was classified as Sochon, a sub-unit constituting the village, in that the number of settlements constituting the village in the Bronze Age was mostly less than five. There are numerical differences between Jungchon and Daechon, and the distribution pattern does not necessarily coincide with the hierarchy. The three individual residential groups of Bunto Village in Hwangsan-ri are Jungchon composed of complex communities of blood relatives with each family community, and a stabilized village landscape was created in the Gusancheon area. In the area of Baekpo Bay, Bronze Age villages formed a landscape in which small villages were scattered around the rivers and formed a single-layered relationship. Dolmens (tombs) were formed between the villages and villages, and seem to have coexisted. Sochondeul is a family community based on agriculture, and it is believed that self-sufficient stabilized rural villages that live by acquiring various wild resources in rivers, mountains, and the sea formed a landscape.

This study was performed to compare the transcultural differences on perimenstrual discomforts, menstrual attitudes and sex role acceptance between Korean and American college students. The subjects, 2557 nursing students were selected from 13 universities all around Korea, and 4 universities in the eastern, western, and middle areas of the United States. The data were collected using the MDQ (Menstrual Distress Questionnaire by Moos), the MAQ(Menstrual Attitude Questionnaire), and the Sex Role Acceptance Scale, the subjects answered the MDQ for three points (premenstrual, menstrual, intermenstrual based on their recollections) between July, 1996 and April, 1997. The findings are as follows : 1. There were significant differences in the age of menarche, duration of menstruation, and menstrual cycle between the Koreans and the Americans. 2. As for sex role acceptance, Americans more frequently denied the traditional female role than did Koreans. 3. There were significant differences between the two groups on five categories of menstrual attitude (menstruation is a phenomena that weakens women physically and psychologically, menstruation is a bothersome phenomena, menstruation is a natural phenomena, menstruation onset is a predictable phenomena, and menstruation is a phenomena that does not influence womens' behaviors non is expected to). 4. For the menstrual discomfort scores, there were significant differences between the two groups on all six categories of the MDQ(pain, attention deficit, behavioral changes, AMS response, water retention, and negative emotion) for the three points (premenstrual, menstrual, intermenstrual period). 5. The most common complaints for the Korean women were pain during the perimenstrual period and fatigue during the intermenstrual period. In contrast, for the Americans the most common complaint was negative emotions during the perimenstrual period, but less pain than the Koreans, and a similarity to Koreans during the intermenstrual period. 6. Regularity of the menstrual cycle was positively correlated with age of menarche, menstrual cycle, and duration of menstruation. 7 For the interrelationship between of Perimenstrual discomforts, menstrual attitudes, and sex role acceptance, there were significant correlations for both group as follows : First, the MA category "menstruation is a bothering phenomena" was negatively correlated with sex role acceptance, second, the MA category "menstruation is a phenomena that weakens the women physically and psychologically" was positively correlated with the MA category "menstruation onset is a predictable phenomena." For the further research, it is recommended that efficient nursing intervention programs for perimenstrual discomforts, be developed and qualitative research to demonstrate the cultural differences as the feminism view point be done.

Women in their 30s and 40s, who are at the center of "ageless" and "down-aging" consumer trends, are likely to encounter problems with fitting and size conformity when they wear casual clothes targeting women in their 20s. Hence, differences in upper body sizes and body types between women in their 20s and women in their 30s and 40s were analyzed. The data for this study was from the 6th Size Korea survey of body measurements of 1,675 female adults in their 20s-40s. SPSS 21.0 for Windows was used for analysis of the collected data. To examine differences in average upper body size between women in their 20s and women in their 30s and 40s, descriptive statistics and independent sample t-tests were conducted. Factor and cluster analyses were used to classify body types by age groups. Comparing direct measurement items showed that women in their 20s tend to have higher average values for most height-related items-including body height-and lower average values for circumference, thickness, and width than women in their 30s and 40s. Factors in determining the upper body shapes of women in their 20s to 40s were narrowed to five; through a cluster analysis, upper body shapes of women were classified into three body types as follows. Type 1 women are shorter and thinner with small frames; Type 2 women have the highest vertical values for their upper bodies and average values for obesity-related categories of circumference, thickness, and width. Type 3 women are the shortest and has the highest body mass index (BMI), verifiable as obese. By analyzing differences in body type distribution according to age groups, it was found that more than 90% of women in their 20s belong to Types 1 and 2. On the other hand, most women in their 30s and 40s are identified as Type 3.

Purpose: Traditionally the patients with early stage non-Hodgkin's lymphoma of the head and neck was treated with radiotherapy. But the results were not satisfactory due to distant relapse. Although combined treatment with radiotherapy and chemotherapy was tried with some improved results and chemotherapy alone was also tried in recent years, the choice of treatment for the patients with early stage non-Hodgkin's lymphoma of the head and neck has not been defined Therefore, in order to determine the optimum treatment method, we analysed retrospectively the outcomes of the patients with Ann Arbor stage I and II non-Hodgkin's lymphoma localized to the head and neck who were treated at Severance Hospital. Materials and Methods: 159 patients with stage I and II non-Hodgkin's lymphoma localized to the head and neck were treated at our hospital from January, 1979 to December, 1992. Of these patients, 114 patients whose primary sites were Waldeyer's ring or nodal region, and received prescribed radiation dose and/or more than 2 cycles of chemotherapy. were selected to analyze the outcomes according to the treatment methods ( radiotherapy alone, chemotherapy alone. and combined treatment with radiotherapy and chemotherapy ). Results: Five year overall actuarial survival of the patients whose Primary site was Waldeyer's ring was $62.5\%.$ and that of the Patients whose primary site was nodal region was $53.8\%$ There was no statistically significant difference between survivals of both groups. Initial response rate to radiotherapy. chemotherapy, and combined treatment was $92\%,\;83\%,\;94\%$ respectively, and 5 year relapse free survival was $49.9\%,\;52.4\%,\;58.5\%$ respectively ( statistically not significant ). In the patients with stage I. 3 year relapse free survival of chemotherapy alone group was $75\%$ and superior to other treatment groups. In the Patients with stage II, combined treatment group revealed the best result with $60.1\%$ of 3 year relapse free survival. The effect of sequential schedule of each treatment method in the Patients who were treated by combined modality was analyzed and the sequence of primary chemotherapy + radiotherapy + maintenance chemotherapy showed the best result ( 3 year relapse free survival was $79.1\%).$ There was no significant survival difference between BACOP regimen and CHOP regimen. Response to treatment was only one significant (p(0.005) prognostic factor on univariate analysis and age and mass size was marginally significant ( p(0.1). On multivariate analysis, age (p=0.026) and mass size (p=0.013) were significant prognostic factor for the relapse free survival. Conclusion: In summary, the patients who have non-Hodgkin's lymphoma of the head and neck with stage I and mass size smaller than 10 cm, can be treated by chemotherapy alone, but remainder should be treated by combined treatment method and the best combination schedule was the sequence of initial chemotherapy followed by radiotherapy and maintenance chemotherapy.

This study was to investigate the effect of soyabean isoflavones (SIF) on onset of puberty, serum hormone concentration, and gene expression in hypothalamus, pituitary and ovary of female Bama miniature pigs. Fifty five, 35-days old pigs were randomly assigned into 5 treatment groups consisting of 11 pigs per treatment. Results showed that dietary supplementation of varying dosage (0, 250, 500, and 1,250 mg/kg) of SIF induced puberty delay of the pigs with the age of puberty of pigs fed basal diet supplemented with 1,250 mg/kg SIF was significantly higher (p<0.05) compared to control. Supplementation of SIF or estradiol valerate (EV) reduced (p<0.05) serum gonadotrophin releasing hormone and luteinizing hormone concentration, but increased follicle-stimulating hormone concentration in pigs at 4 months of age. The expression of KiSS-1 metastasis-suppressor (KISS1), steroidogenic acute regulatory protein (StAR) and 3-beta-hydroxysteroid dehydrogenase/delta-5-delta-4 isomerase ($3{\beta}-HSD$) was reduced (p<0.01) in SIF-supplemented groups. Expression of gonadotropin-releasing hormone receptor in the pituitary of miniature pigs was reduced (p<0.05) compared to the control when exposed to 250, 1,250 mg/kg SIF and EV. Pigs on 250 mg/kg SIF and EV also showed reduced (p<0.05) expression of cytochrome P450 19A1 compared to the control. Our results indicated that dietary supplementation of SIF induced puberty delay, which may be due to down-regulation of key genes that play vital roles in the synthesis of steroid hormones.

Five hundred seventeen farmers(214 males and 303 females), over age 30 and living in Suh San County, Unsan township, were examined to determine the prevalence of peasants syndrome. Using the health interview questionnaire, the farmers were asked whether they had any of eight subjective symptoms during the past one month before the survey, October 1979. Those symptoms reported were scored based on a pre-determined point system. The farmers with high symptom scores(7 points or more) were further examined by the liver function test. In addition, all the sample(517 cases) were subjected to the examination of urinalysis and blood pressure. The liver function test is also undertaken for those farmers with high symptome scores(7 points or more) and those with abnormal findings in urinalysis and blood pressure. The results are summarized below: 1) 156 out of 517 farmers(30.2%) have had seven points or more of the symptom scores. Among the eight major symptoms, 72% of the farmers complained of lumbago. 2) The prevalence of peasant's syndrome were higher among females and the older age group. The symptom scores of this syndrome were slightly higher among women who have had many children (e. g. 4 or more). 3) The prevalence of peasant's syndrome was also related to the level of one's education-the lower education groups were found to have higher symptom scores of this syndrome. This may be due to the fact that the lower education groups are more exposed to manual labor. 4) The points of the peasants syndrome were higher in hypertensive farmers and those with abnormal findings of urinaly sis. 5) It was reported, in Japan, that those with high scores of the syndrome are more likely to have an abnormal findings in the liver function test. However, in this study it was observed that there was no significant difference between those with high scores of the syndrome (7 points or more) and those with low score of the syndrome(6 points or less) in the prevalence of abnormal liver function. As this study indicates that the point system given for the peasant's syndrome is closely related to the high bleod pressure and abnormal urinalysis(and to some extent to the abnormal liver function), there is a need to study peasant's syndrome more extensively. Such an effort will serve to detect varonic disease conditions among farmer's towards better management of farmer's health, which is vitally important for rural development in Korea.

Two studies were conducted to investigate the effects of anti-diarrhoeal herbs on growth performance, nutrient digestibility, and meat quality in pigs. In Exp 1, 150 weanling-growing piglets (average BW = $7.5{\pm}0.24$ kg, average age = $27{\pm}1$ d) were allotted into one of the five dietary treatments, including: i) CON, basal diet, ii) DP, basal diet+1 g/kg date pits, iii) JH, basal diet+0.5 g/kg Japanese-honeysuckle, iv) HCT, basal diet+1 g/kg houttuynia cordata thunb, and v) LE, basal diet+1 g/kg laquer tree extract. From wk 0 to 5, the JH, HCT and LE groups presented higher (p<0.05) ADFI, ADG and gain/feed ratio (G/F) than CON and DP groups. During wk 5 to 10, Pigs fed JH, HCT and LE diets indicated higher (p<0.05) ADG and ADFI than the pigs fed CON and DP diets. During the entire experimental period, a significant increase of ADG appeared in JH, HCT and LE (p<0.05). Pigs fed JH, HCT and LE diets got a higher (p<0.05) ADFI than the pigs fed CON and DP diets. Pigs fed diets with supplementations of herb additives revealled lower (p<0.05) score of diarrhea pigs during d 2 to d 6 compared with pigs fed CON diet. In Exp 2, 60 growing-finishing barrows and gilts (average BW = $54.10{\pm}1.20$ kg, average age = $54{\pm}3$ d) were allotted to three treatments: i) CON, basal diet; ii) YG, basal diet+1 g/kg yellow ginger and iii) HR, basal dietary+1 g/kg hoantchy root, respectively. From wk 0 to 5, Dietary supplementation of YG and HR enhanced (p<0.05) ADG. No difference was found between YG and HR treatments. During, wk 5 to 10, ADG also was observed higher in YG and HR treatments than CON group (p<0.05). Additional, YG had the highest ADG (p<0.05) among treatments. There was always an increase of ADG in YG and HR (p<0.05) through all periods. HR treatment showed a lower (p<0.05) score of diarrhoeal pigs on d 1and d 2 compared with CON treatment. Pigs fed YG and HR diets had a higher (p<0.05) longissimus muscle area (LMA) than pigs fed CON diet. In conclusion, anti-diarrhoeal herbs can improve growth performance, and prevent diarrhea incidence in pigs, it can also increase LMA in finishing pigs.

Purpose : This study was conducted to evaluate the red cell indices and frequency of iron deficiency anemia based on the feeding patterns of nine-month-old infants. Methods : Blood tests were performed on 253 nine-month-old infants, who visited Il Sin Christian Hospital for health check-ups from January to December 2007. Their parents answered telephonic questions regarding their feeding patterns and weaning foods. Results : Three infants groups were created according to feeding patterns before they started weaning foods. One group was exclusively breast-fed (48.6%), another had mixed feeding (27.3%), and the third had artificial milk feeding (24.1%). Red cell indices (hemoglobin, hematocrit, MCV, MCH) of the breast-fed group were comparatively lower than those of the other two groups (P<0.05). Twenty-five infants (9.9%) were diagnosed with iron-deficiency anemia. According to feeding patterns, the frequency of anemia was highest in the breast-fed group. Six infants who started weaning foods before six months of age (113 infants) were diagnosed with iron-deficiency anemia (5.3%), and nineteen who started after six months of age (140 infants) were diagnosed with iron-deficiency anemia (13.6%). Conclusion : When nine-month old infants visit hospitals for health check-ups, pediatricians must consider their feeding pattern and weaning foods histories, and then recommend screening blood tests for iron-deficiency anemia.

The purpose of orthodontic treatment is to achieve normal occlusion and good facial esthetics for individual patients. To produce harmonized facial balance, treatment planning for patient who require orthodontic treatment should include both a hard tissue and soft tissue cephalometric analysis. Author studied to derive the normal standards of soft tissue profile in Koreans by roentgenocephalometric analysis. For this study 12 soft tissue profile landmarks were plotted and 23 linear length, 9 soft tissue thickness, 8 vertical height length, 12 angles of soft tissue profile, and 3 vertical proportion were measured. The subjects consisted of 166 males and 209 females from 7 to 19 years with normal occlusion and acceptable profiles, and were divided into five groups according to age. The obtained results were as follows; 1. From the basis of N-Pog (Nasion-Pogonion) plane, the growth of facial soft tissue in the middle region especially nose area was greater than others facial region. 2. From the basis of G-Pog' (Glabella-soft tissue Pogonion) plane, the values of linear measurement of soft tissue Nasion and Inferior labial sulcus decreased and nose tip grew forward as growing older. 3. The growth of the facial soft tissue thickness was greatest in superior labial sulcus and the thickness of soft tissue nasion gradually became thinner as growing old. 4. The thickness of upper and lower lip was 14.47mm, 14.57mm in adulr male, 12.76mm, 13.78mm in adult female. 5. The soft tissue thickness of the lower lip was thicker than that of upper lip in all age groups and both sexes, 6. The vertical length of the upper and lower lips were 25.04mm, 49.97mm in adult male and 23.50mm, 48.39mm in adult female. 7. By the significant test, there were significant difference between male and female in fifth adult group on all vertical length measurements of lower face. 8. In fifth adult group, the perpendicular distance from LS, LI to Steiner's line and Ricketts' esthetic line were as follow; Steiner line to LS, LI were 7.98mm, 5.84mm in male. Steiner line to LS, LI were 6.71mm, 5.08mm in female. Ricketts' esthetic line to LS, LI were -0.40mm, 1.72mm in male. Ricketts' esthetic line to Ls, LI were -1.38mm 0.65mm in female. 9. In fifth adult group, the facial convexity angle and lower facial component angle were $171.17^{\circ}142.94^{\circ}$ in male and $172.5^{\circ}$, $144.41^{\circ}$ in female.

This study aims to understand the characteristics of Korean language learners and propose appropriate teaching plans for them through a focus group interview with Korean language instructors who had experience in teaching Korean at university-attached institutions in Hong Kong. For this purpose, the investigator interviewed ten instructors who taught Korean for at least five years. Korean language learners in Hong Kong who were in their twenties, but there were diverse age groups, including those in their fifties or older. Their motivations for learning Korean included the Korean Wave and the influence of support from the Continuing Education Fund by the Hong Kong government. Korean language learners in Hong Kong were characterized by active learning desire and effort, continuous learning intention, passive performance in speaking, and sensitivity to the disclosure of private information. Based on these findings, the study proposes to devise teaching and learning methods based on various age groups in a class and teaching methods for speaking that reflect the characteristics of Korean language learners in Hong Kong to teach Korean more effectively. The study is significant as a field study that examines the learning motivations, learning attitudes, and difficulties with Korean study of Korean language learners based on an unprecedented survey of the characteristics of common local Korean learners in Hong Kong.
