The purpose of this article was to get hold of adolescent's needs for sex knowledge and to reveal their understanding of sex. These results may be applied to the sex education and counselling for adolescent. The participants of study were 267 students (females, 144 ; males, 123) who were the first and second grade form 1 middle and 2 high schools. They were asked to describe 3 questions that they wanted to know or to learn about sex. Their questions about sex were total 779(girls, subtotal 456, mean 3.2, boys, subtotal 323, mean, 2.6). These questions categorized to 9 items by content analysis. The items were ‘sexual drive, behavior and tendency(229, 29.4%)’ , ‘anatomy and physiology of reproductive system(140, 18.0%)’, ‘reproduction(131, 16.8%)’, ‘concept of sex(31, 4.0%)’, ‘acquaintance between the other sexes(17, 2.2%)’, and ‘the others(9, 1.2%)’ in order of frequency. The most frequent item that the student want to know or team about sex was ‘sexual drive, behavior and tendency’ except girls of sophomore in middle school. There were several features in participants' needs for sex knowledge as respects of the understanding of sex- biological sex, gender, and sexuality. The prominent feature in knowledge need of bio logical sex was that the participants had the interests according to their biological sex. They had the negative attitude to the phenomenons (ex, menstruation and pregnancy, phimosiectomy, etc) that they experienced or would experience due to their biological sex. A part of them asked the questions based the misconceptions and used the slangs or ‘××’, ect. to name the male or female genitalia. The male students wanted to know the female genitalia. The participants' understanding of gender reflected the sexism of our society, but they didn't accept and had doubts about the dual, hierarchical structure of that. The students, especially female seemed to be powerless to the harms of the sexual violence. Girls had much interest in their appearances and complained to our sexual culture that women comforted and served men. The participants had the dual perspective that the sexuality as respects of physiologic phenomenon was considered as natural but that as related to heterosexuals was as negative. And they deemed that men's sexual drive was stronger than women's and was difficult or was not able to be inhibited. They had much interests in homosexuality but reflected the negative attitude to that in our society. Adolescent felt wonder why the expressions of sexuality of adult were permitted but theirs were not. Lastly, a part of boys substituted querying the sexuality of animals for asking that of human. Maybe it was because of the embarrassment to talk about human's sexuality directly. The teenaged participants understood that the sex had not only the biological meanings but also the sociocultural meanings. They regarded the sex as natural and wanted to know it, but they had conceptions that it was difficult and embarrass to talk about it openly and directly.

This study was performed to establish the cephalometric standards in Downs analysis and to compare them with other races. The lateral cephalograms of 88 Korean children (47 boys, 41 girls) with normal occlusion and acceptable profile between 7 and 11 years of age were taken and Downs analysis was done. Results were as follows: 1. Norms of Korean boys, girls and both sexes at 7, 9, 11 years of age by Downs analysis were established. 2. There were no statistically significant differences between boys and girls about ten measurements in each group, but significant differences in the occlusal plane angle, lower 1 to occlusal plane angle, interincisal angle, upper 1 to APog plane among 3 groups(p<0.05)(p<0.01). 3. Facial angle, AB plane angle, Y-axis, lower 1 to occlusal plane angle and lower 1 to mandibular plane angle showed increasing tendency whereas angle of convexity, mandibular plane angle, occlusal plane angle and interincisal angle did decreasing tendency according to aging. 4. In comparison among races, measurements in Korean children were generally larger than those of Caucasian and Greek except for small interincisal angle, but Korean were similar to Japanese, Chinese, Israeli, Negro about all measurements.

After accepting the modernized western culture, we, the Koreans, had traditionally patriarchal valuation on the family life, which has been changed into modernize on in these days. Under these circumstances, we examined into family consciousness of workmen, office workers and student of universities in Pusan with questioning papers by inquiring their general views of family, marriage, family planning , and inheritance. The results obtained can be summarized as follows. 1. General views of family 1)Most of them prefer nuclear family to gross one in structure of family. In decision of family's affairs, the lower educated persons want an unilateral relationship, which means unconditional obdience to their parent's opinion. they are more concerned about the profit of the family than that of individual. on the other hand, they want 2-generations nuclear family system. 2) Concerning children's future affairs, they want compromising method. 2. Views of Marriage 1) Date with the other sex motivated their desire to improve social adaptation and social association. 17-19 year old students regard date as a preparatory stage of marriage. They consider it most desirable date to enjoy free conversation each other. They hope their date partners are high educated. 2) The conditions of mate selection are in order character, health, vitality in living, appearance and education. The less educated placed an emphasis on vitality in living. 3) They are not much interested in marital harmony. If parents are against their marriage an account of bad marital harmony, they will take into consideration about it. 4) They wish to keep purity before marriage, as possible. They want engagement period of 6 months. Any agreeable reasons shall compel them to break off their appointment. 5) they consider it ideal for mate's age to be 26-30 years old, and also think it affirmative to follow their parent's agreement in marriage. It is considerable that they put off their marriage only because they have lots of work to do before marriage. 6)Marriage declaration is to be made on the wedding day. It still exists that they don't want to marry when they are inth same surname and family tree. But it is clear that they don't regard it as the reason of breaking off the betrothal. 3. Family Planning 1) They are willing to agree to the campaign "just two is enough". They want a son and a daughter. Even though they have two daughters, they won's bear child to get son. 2) the lower educated persons are ignorant of the method of birth control. 4. Inheritance 1)Most of them say householder inheritance is to be kept up continuously. It is reasonable that anyone who can afford to perform religious service should bear it responsibility. 2)They don't want the difference in inheritance as the conscious to the conscious of the equality of the sexes spread widely into our society, but it is worthy of notice that some of them still don't mind unequal treatment. 3) When they have no child, the property inheritances are in order his wife and his parents. According to above mentions, we conclude like this: Their consciousness of marital harmony, marriage, family planning and inheritance shows definitely passive rationism in the transitional stage which is mixed with western individualism and traditional feudalism. On account of being lack of steady fast self-conscience, they can not make their positive reaction on anything. Finally, we should make every possible efforts to have our firm self-conscience through the re-education.

Male adults of bean bug, Riptortus clavatus Thunberg (Heteroptera: Alydidae), release aggregation pheromone (AP) attracting both sexes of adult and nymphs, which its egg parasite, Ooencyrtus nezarae (Hymenoptera: Encyrtidae) exploits the pheromone to find host. The AP consists of three components; (E)-2-hexenyl (Z)-3-hexenoate (E2HZ3H), (E)-2-hexenyl (E)-2-hexenoate (E2HE2H), and tetradecyl isobutyrate (TI). We analyzed composition of the pheromone components of bean bugs from different geo graphical locations of Korea and Japan. The attractiveness of different blends of AP components to R. clavatus was also tested in the fields in Jinju, Korea and in Kumamoto, Japan. Composition ratios (E2HZ3H: E2HE2H:TI) of the AP of Jinju and Iksan populations were 1:1.4:0.2 and 1:0.8:0.2, and those of Tsukuba and Kumamoto populations were 1:2.8:0.2 and 1:1.5:0.1, respectively. In field tests, traps baited with ratio of 1:1:1 (E2HZ3H:E2HE2H:TI=16.7:16.7:16.7mg/rubber septum) and 1:1:0.5(E2HZ3H:E2HE2H:TI= 20:20:10mg/rubber septum) attracted significantly greater number of adult bugs than that of 1:5:1 (E2HZ3H:E2HE2H:TI=7.1:35.7:7.1mg/rubber septum).

Objectives This study was performed to investigate the cut-off values of abdominal circumference and Body Mass Index(BMI) according to Sasang Constitution. Methods A total of 1,773 persons, namely 440 male people and 1,333 female people, in ages from 40 to 69 years old, participated in this research. They are all included in the community based Genomic cohort in Wonju in years from 2006 to 2013. The diagnostic criteria of metabolic syndrome was used followed by the National Cholesterol Education Program in Adult Treatment Panel III (NCEP ATP III) and Asian pacific guideline for only abdominal obesity. Results The prevalence of metabolic syndrome was 34.8% for men and 37.6% for women in this research. Taeeumin was the highly significant risk type for the metabolic syndrome in both sexes. Cut-off values of abdominal circumference were 88.3 cm in men, 80.3 cm in women, and cut-off values of BMI were $24.2kg/m^2$ in men and $25.3kg/m^2$ in women. For men, cut-off values of abdominal circumference were 79.5cm in Soyangin, 88.8 cm in Taeeumin and 79.5 cm in Soeumin, and cut-off values of BMI were $23.2kg/m^2$ in Soyangin, $25.6kg/m^2$ in Taeeumin and $20.6kg/m^2$ in Soeumin. For women, cut-off values of abdominal circumference were 76.3 cm in Soyangin, 80.3 cm in Taeeumin and 76.8 cm in Soeumin, and cut-off values of BMI were $22.4kg/m^2$ in Soyangin, $24.9kg/m^2$ in Taeeumin and $21.3kg/m^2$ in Soeumin. Conclusions Although 90 cm in men, 80 cm in women as an Asian pacific guideline were regarded as quite approximate to the mean value of abdominal circumference and $25kg/m^2$ to BMI. But if the results could be allocated in terms of the Sasang constitutional method, the cut-off values for Soyangin and Soeumin should be lowered than now.

6-[(N-3,4-Difluorophenyl)amino]-7-chloro-5,8-quinolinedione(RCK4) was tested for antifungal activities, against systemic infections with Candida albicans in normal mice. The therapeutic potential of RCK4 had been assessed in comparison with ketoconazole and fluconazole. RCK4 had $ED_{50},\;0.30{\pm}0.14$ but ketoconazole and fluconazole had $ED_{50},\;8.00{\pm}0.73,\;10.00{\pm} 0.43mg/kg$ respectively. Intraperitoneally administered RCK3 at the $ED_{50}$ for 7 days and 14 days reduced Candida albicans colony count in the kidneys and liver as well as ketoconazole and fluconazole at these $ED_{50}$. And administered RCK4 at the $ED_{50}$ for 14 days improved survival rates as well as ketoconazole. Acute oral toxicity studies of RCK4 were carried out in ICR mice of both sexes. These acute oral toxicities of RCK4 were low and $LD_{50}$ values were over 2,850mg/kg in ICR mice. The genotoxicities of RCK4 had been evaluated. RCK4 was negative in Ames test with Salmonella typhimurium and chromosomal aberration test in CHL cells. The clastogenicity was tested on the RCK4 with in vivo mouse micronucleus assay. RCK4 did not show any clastogenic effect in mouse peripheral blood and was negative in mouse micronucleus assay. These results indicate that RCK4 has no genotoxic potential under these experimental conditions.

Purpose: This study was performed to evaluate condylar surface changes and remodeling after orthognathic surgery using three-dimensional computed tomography (3D CT) imaging, including comparisons between the right and left sides and between the sexes. Materials and Methods: Forty patients (20 males and 20 females) who underwent multi-detector CT examinations before and after surgery were selected. Three-dimensional images comprising thousands of points on the condylar surface were obtained before and after surgery. For the quantitative assessment of condylar surface changes, point-to-point (preoperative-to-postoperative) distances were calculated using 3D processing software. These point-to-point distances were converted to a color map. In order to evaluate the types of condylar remodeling, the condylar head was divided into six areas (anteromedial, anteromiddle, anterolateral, posteromedial, posteromiddle, and posterolateral areas) and each area was classified into three types of condylar remodeling (bone formation, no change, and bone resorption) based on the color map. Additionally, comparative analyses were performed between the right and left sides and according to sex. Results: The mean of the average point-to-point distances on condylar surface was $0.11{\pm}0.03mm$. Bone resorption occurred more frequently than other types of condylar remodeling, especially in the lateral areas. However, bone formation in the anteromedial area was particularly prominent. No significant difference was found between the right and left condyles, but condylar surface changes in males were significantly larger than in females. Conclusion: This study revealed that condylar remodeling exhibited a tendency towards bone resorption, especially in the lateral areas. Condylar surface changes occurred, but were small.

Purpose: The purpose of this study was to investigate the epidemiologic characteristics of patients who visited emergency departments (EDs) after intentional poisoning in Korea. Methods: This study retrospectively analyzed the data of of 23 hospitals during a five-year period, between 2011 and 2015. We included patients who inflicted injury to themselves - attempt of suicide - by means of poisoning. Results: A total of 18,121 patients visited an ED after intentional poisoning. Among them, 58.3% were females; however, there were more males among those aged 60 years or older. The mortality rate for males was 8.6%, which was 3.1 times higher than that for females with 2.8%. The most common poison was pesticides (35.4%) in males and sedative-hypnotics (44.0%) in females. The most common causative agent of death was pesticide in both sexes (75.2% and 65.3%, respectively). Since the production of paraquat was discontinued in 2011, the number of deaths from pesticide poisoning has decreased. The mortality rate declined in both males and females, from 12.6% and 4.5% in 2011 to 7.1% and 2.1% in 2015, respectively. Conclusion: In this study, we analyzed the epidemiologic characteristics of intentional poisoning, especially the frequency of suicide attempts by gender and age group, the cause of suicide, and the causative agent. This can be used as basic data for establishing policies to reduce and prevent suicide attempts by poisoning.

We reviewed 15 cases of mesothelioma of the pleura, of which three cases were localized benign form and 12 cases were malignant diffuse form. The tumors were distributed equally in both sexes, and occured most commonly in fifth to seventh decades. The history of exposure to asbestos was present in only one case. The chief complaints were mainly chest pain and dyspnea. Associated symptoms were cough, sputum, hemoptysis, weight loss, anorexia, chill. On physical examination, unilateral, decreased breathing sound was main feature. The simple chest radiograph showed masses in all localized mesotheliomas (100%) and in 2 diffuse mesotheliomas (17%). 8 cases of diffuse mesotheliomas (67%) showed unilateral pleural effusions. Pleural effusions were mainly bloody (67%), and almost all were exudates. In all localized mesotheliomas, final diagnosis was made by open thoracotomy. In diffuse mesotheliomas, final diagnosis was made by open thoracotomy in 7 cases, chest wall mass biopsy in 2 cases, thoracoscopic biopsy in 1 case, pleural biopsy in 1 case, and pleural biopsy combined with axillary lymph node biopsy in 1 case. Localized mesotheliomas were treated by simple excision with good prognosis. In diffuse mesotheliomas, surgical treatment (pleuropneumonectomy, pleurectomy), chemotherapy, or radiotherapy, alone or in combination, were used with dismal prognosis. The prognostic factors were not found due to the small number of cases, incomplete follow up, and early drop out.
