  • The carcinogenic potential of steviol, a metabolite of/ stevioside (a compound that is used as a sweetener for food and drink), was examined in hamsters of both sexes. Groups of 55 male and 55 female hamsters were given diets containing steviol at 0, 100 and 500 mg/kg diet for 22 months in males and 18 months in females. After 6, 12 and 22 months in males and 18 months in females. hamsters from each group were sacrificed for hematological and biochemical tests. Growth food utilization and consumption, general appearance and mortality were similar in treated and control groups. The mean life span of hamsters given steviol was not significantly different from that of the controls. No treatment-related changes were observed in hematological, urinary and biochemical values at any stage of the study. There was no significantly altered development of neoplastic or non-neoplastic lesions attributable to steviol treatment in any organ or tissue. The highest level oj steviol in the diet which still causes no effects in hamsters was 500 mg/kg diet, under the experimental conditions used.

  • The purpose of study examined the changes of the man's underclothes from the ancient ages to the early modern ages. The method of study researched literatures and possessions of the museum. In ancient ages, a suit of clothes had the functions of both underclothes and outer garments. In middle ages, underclothes were not exposed and the importance was not recognized while they were worn to show the sense of sin and humility or to punish criminals. In early modern ages, the importance of underclothes recognized as they were exposed. In Renaissance period, the fashion of the day influenced much on the underclothes. In Baroque ages, the functions of underclothes were different according to sexes and men wore underclothes to show their social status. As the outer garments were shortned, shirt wwere also conspicuously exposed. In Rococo ages, drawers were tightened due to the influence of outer garments, men exposed their shirts to show the social status and underclohtes were usually worn to express sexual attraction. Men's underclothes had the functions of class distinction from the ancient ages to the modern ages, except the middle ages and underclothes had the additional functions such as supporting body-shape and sex attraction. The fashion of the day influenced on the changes of the shapes of the shapes of men's underclothes and the changes of outer garments were reflected on underclothes.

  • The purpose of this study was to compare the beverage consumption by gender and season in elementary school children and to investigate the role of beverage consumption patterns on their daily nutrient intakes and BMIs. Beverage consumption and dietary energy intake in 160 elementary school students in the Gyeongnam area were measured by a beverage frequency and quantity questionnaire and three 24-hour dietary recalls during winter and summer. The number of drinking moments per month, the amounts of beverage per day, and the energy from beverage consumption were not different between winter and summer. In summer, the contribution of energy from sweetened beverage to the daily energy intake in girls accounted for 13.5% which was significantly higher compared to 7.7% in boys. In girls, the consumption of health beverage showed a significant correlation with various nutrient intakes in winter. Meanwhile, the sweetened beverage intake was negatively correlated with energy, protein, vitamin A and niacin intake in summer. Consumption of most of the beverages, including sweetened beverages, were not related with BMI in both sexes and both seasons, except functional drinks which were related with BMI in boys in winter.

  • Depressive status of the adolescence in 437 normal, 416 orphan, 133 physically handicapped and 109 deaf-mute children were compared with the Self- Rating Depression Scale developed by Zung, from April 26 to July 4, 1976. The subjects were divided into two groups, early adolescence for age of 10 to 14 and ate adolescence of age of 15 to 18. The results were as follows : 1. The depression score was higher in late adolesce co than in early adolescence except deaf - mutes, 2. The depression score was not different significantly between the sexes in all groups. 3. The depression score was significantly higher in the group of orphan, physically handicapped and deaf - mute children then in the normal. 4. The depression score was significantly higher in the orphans than in the physically handicapped children. It showed tendency to be higher in the deaf - mutes than in the physically handicapped children. 5. In comparison with the rank order of the Self - Rating Depression Scale items, normal group was inclined to have psychological symptoms in higher rank order, but orphan and deaf - mute group was inclined to have somatic symptoms in higher rank order.

  • Investigations were made on population biology of Pampus echinogaster (Basilewsky, 1855) in the coastal areas of Korea, Yellow Sea, between August 2005 and July 2006. Population structure was not significantly different between male and females. Monthly variation of gonadosomatic index (GSI) of both sexes defined spawning period extending from March through July. A similar pattern was also observed in change at maturity stages. For males and females GSI was positively correlated with hepatosomatic index (HSI). Fecundity, ranging from 41,250 to 103,610 eggs, was related to body size, indicating that body size is the useful determinant of fecundity. The sexual maturity ($L_{50}$) was estimated as 14.98 cm TL for males and 19.32 cm TL for females. Parameters of growth estimated by the modified von Bertalanffy growth function model showed that the values of $L_{\infty}$ and K for combined data were 39.12 cm TL and 0.65 $yr^{-1}$. The growth performance index of this study (2.75) was higher than that of the previous study (2.45). This difference could be attributed to sampling method. The recruitment patterns indicated one normally distributed group. Percentage of the recruitment was 51.04% in the spawning season and the highest in August (19.78%).

  • This study investigated the effects of Korean parents' family-of-origin experiences, marital conflict, open or dysfunctional communication with their children, children's coping behaviors on their behavior problems as a function of a child's sex. Theoretical models for both sexes were constructed based on the results. Two hundred and nine boys and one hundred and ninety six girls of 4th and 5th grades from two elementary schools filled out the questionnaires to assess their communication with the parents, their problem-focused coping behaviors, and their internalizing and externalizing behavior problems. Four hundred five parents of these children answered the questionnaires to assess differentiation for the family-of-origin and the marital conflict. The results were as follows. Boys' path pattern showed that the fathers' differentiation from the family-of-origin effected their sons' internalizing and externalizing behavior problems through parent-child dysfunctional communication. Girls' path exhibited two different patterns. One is that the mothers' differentiation from the family-of-origin effected their daughters' internalizing and externalizing behavior problems through parent-child dysfunctional communication. Another one is that the mothers' differentiation from the family-of-origin influenced children's internalizing behavior problems through daughters' problem-focused coping behaviors as well as parent-child dysfunctional communication.

  • The genetic factors that contribute to the development of coronary artery disease (CAD) are poorly understood. It is likely that multiple genes that act independently or synergistically contribute to the development of CAD and the outcome. Recently, an insertion/deletion (I/D) polymorphism of the human angiotensin I-converting enzyme (ACE) gene, a major component of the renin-angiotensin system (RAS), was identified. The association of the ACE gene D allele with essential hypertension and CAD has been reported in the African-American, Chinese, and Japanese populations. However, other studies have failed to detect such an association. It has been suggested that these inconsistencies may be due to the difference in backgrounds of the population characteristics. In the present study, we investigated the I/D polymorphism of the ACE gene in 103 subjects of both sexes, consisting of 59 normal controls and 44 patients with hypertension. The allele and genotype frequency were significantly different between the hypertensive and control groups (p < 0.01). Among the three ACE I/D variants, the DD genotype was associated with the highest value of the mean systolic blood pressure [SBP] and mean diastolic blood pressure [DBP] (p = < 0.05) in men, but not in women. In the overall population, the mean SBP and DBP was highest in DD subjects, intermediate in I/D subjects, and the least in II subjects.

  • Purpose: The purpose of this study was to compare and examine gender role identity and sexual attitude according to sex among college students. Method: The subjects consisted of 1,118 college students. The tool for gender role identity and sexual attitude was the Korea Gender Role Identity Inventory(KGRII) of Lee, Kim and Koh(2002) and the Sexual Attitude Scale of Koh, Kim and Lee(2005). The collected data was analyzed using descriptive analyzed statistics, $X^2$ test, Lamda, t-test, ANOVA, Sheffe and Pearson correlation with the SPSS WIN 12.0 program. Result: For male students, undifferentiated role identity type, 36.5%, was the most common but for female students, an androgynous role identity type, 39.3%, was most common. The sexual attitude score according to gender role identity type was 2.9 for the undifferentiated type as the highest score. Of both male and female students, the highest sexual attitude score was the undifferentiated type. Sexual attitude according to general characteristics for male students had a significant difference in major field of study and height and for female students weight. Sexual attitude was significantly related to age, height and weight. Conclusion: These results suggest that gender role identity and sexual attitudes are different between the sexes. This study result contributes to providing basic data for sex education and nursing interventions for college students.

  • The actual burden of head and neck cancer in India is much greater than reflected through the existing literature and hence can be regarded as a 'tip of iceberg' situation. This has further been evident by the recent reports of 'Net-based Atlas of Cancer in India'. South-east Asia is likely to face sharp increases of over 75% in the number of cancer deaths in 2020 as compared to 2000. Since the percentage increase of Indian population has been nearly twice that of the world in last 15 years there is a likelihood of increase in cancer burden with the same proportion. The distribution of population based cancer registries is grossly uneven with certain important parts of the country being not represented at all and hence the current cancer burden is not reflected by registry data. However, the pathetic situation of health care system in major parts of the country as also emphasized by the World Bank, is not suitable to provide anywhere near accurate data on cancer burden. Head and neck cancer (including thyroid lesions) is third most common malignancy seen in both the sexes across the globe but is the commonest malignancy encountered in Indian males. Also oral cavity cancer is the most prevalent type amongst the males and one of the highest across the globe. This article reviews the latest global and national situation with an especial emphasis on head and neck cancer. Furthermore this review focuses on burden in different sub sites at national and global levels.
