The author measured the maximum interincisal distance by means of the sliding caliper. The subjects measured here were 149 healthy Korean males and 229 females, ranging from 15 to 49 years old, with normal occlusion. The results were as follows; 1. The mean value of maximum interincisal distance was $50.03{\pm}0.22mm$. in male and $45.18{\pm}0.14mm$. in female. 2. There was a significant difference in the mean value between male female. 3. The interincisal distances in maximum opening were slightly larger in male than female. 4. There was no significant difference in the mean value between the age groups in Korean adults. But it has been revealed that there was apparent difference in the mean value between 15~19 years and 20~29 years old, in female. 5. It has been appeared that maximum interincisal distance in male was 69mm, minimum 37mm., and maximum interincisal distance in female was 58mm. minimum. 30mm.

This study examined the psychological aspects of a single life with particular focus on the personality ＆ emotional characteristics, the social ＆ behavioral characteristics, marriage, happiness, and sex of singles. The sample consisted of 160 single male and female aged 30 to 49. The results of the questionnaire survey showed that the singles tended to be self-centered, especially when they did not have a plan to get married, and that most of the singles in the 30s wanted to have a friend of the other sex. In the view of marriage, young, male singles were more likely to form a family than old, female singles. Also, female singles, bereaved or divorced, were shown to have fear about marriage and negative attitudes toward marriage more than male, never-married singles did. Regarding the extent of happiness, old, female (rather than young, male) singles tended to be more satisfied with a single life. Besides, old, religious singles were less likely to feel lonely than young, unreligious singles. In addition, it appeared that college-graduated singles had rather liberal view on sex although singles generally showed rather conservative toward sex in this study. Therefore, the findings reveal that singles were self-centered, social, positive view on marriage, somewhat happy of a single life, and having a conservative attitude about sex. Further understanding of a single life in modem society is needed in future studies.

Several studies have shown that the stomach has sufficient alcohol dehydrogenase (ADH) activity to metabolize some amount of orally administered alcohol and the sex-related differences in the first-pass metabolism of alcohol might be associated with differences in the activity of gastric ADH(GADH). The aim of this study was to asses the sex-related differences in GADH in 48 male and 48 female Sprague-Dawley rats aged 1, 4, 10, 15, 20, and 30 weeks which each aged group had same sex ratio. The GADH activity was determined spectrophotometrically at 37$^{\circ}C$. The formation of NADH was monitored at 340nm for 10 minutes in the 1 ml of reaction mixture (0.5 M of Tris-HCl, pH 7.2 + 1.5 M of ethanol + 2.8 mM of NAD + 30 $\mu$l gastric mucosal supernatant). The GADH activity (nM of NADH/min/mg of cytosolic protein) was calculated using molecular extinction coefficient of 6.22 $\textrm{cm}^2$/$\mu$M for NADH. The GADH activities were 2.94$\pm$0.82 (n=48) in female rats and 3.34$\pm$2.17 (n=48) in male rats and had not significant difference between sex. However, the GADH activities were significantly (p<0.01) higher in female (1.91$\pm$0.59 and 3.30$\pm$0.49) than in male (0.68$\pm$0.43 and 1.92$\pm$0.81) of 1 and 4 weeks rats. However, it was significantly (p<0.05) higher in male (6.48$\pm$1.81, 3.65$\pm$1.04 and 5.13$\pm$1.30) than in female (4.23$\pm$1.23, 2.18$\pm$0.77 and 2.56$\pm$0.93) of 10, 20 and 30 weeks rats, respectively. Therefore, the results suggested that sex-related differences of the GADH activities in same aged rats were existed by age.

It is necessary to compare the dietary characteristics among different age groups because different nutritional problems require different dietary applications. This study was performed to identify the nutritional characteristics of Korean diet among different age groups. The study subjects consisted of preschool children(PC), elementary school children(EC), high school students(HS), college students(CS), and adults over 30 years old living in Seoul and the surrounding areas. The subjects over 30 years old were classified to 30-49 years, 50-69 years, and over 70 years. A dietary survey was conducted using 24-hour recall method and data were collected from 2392 subjects. Energy intake was as much as 1771kcal for PC, 2139kcal for EC, 2475kcal for HS, 2276kcal for CS, 1860kcal for 30-49 years, 1715kcal for 50-69 years, 1326kcal for over 70 years. The subjects of PC, EC, HS, and CS groups got about 25% of energy from fat, but the subjects in 30-49 years, 16%, those in 50-69 years, 15%, and those over 70 years, 13%. The energy consumption from protein was about 15% in each age group. Percent of energy intake as Korean RDA was greater than 100% for PC, EC, HS, and male CS groups. The percent intake for RDA of calcium, iron, vitamin A, and vitamin B$_2$was low in most age group. Iron intake was inadequate in female of PC and CS groups, and subjects in 30-49 years and over 70 years. Mean adequacy ratio(MAR) was 0.9 in PC, and decreased with increase of age. Therefore MAR did not reach to 0.7 among subjects over 70 years. Index of nutritional quality(INQ) for calcium, iron, vitamin A, and vitamin B was below 1 in most age groups. From these results, major nutritional problems of each age group were overall inadequate intakes of calcium and iron, excess consumption of protein and fat for PC, EC, HS, and CS groups, and inadequate nutrients intake of subjects over 70 years old. According to these results, each age group seems to need specific nutritional intervention. (Korean J Nutrition 34(5) : 554~567, 2001)

Background: Male breast cancer accounts for less than 1% of all cancer in men and only around 1% of all diagnosed breast cancer. Despite a significant raise in the last 25 years, it still remains a rare disease. Materials and Methods: We conducted a retrospective study from 2004-2011 with 21 male breast cancer patients. We aimed to analyze the epidemiologic data (age, personal and family history), tumor characteristics (size, histological type, location, TNM stage, receptors), surgery, adjuvant chemotherapy and radiation therapy, hormonal therapy and survival (relapse, follow up, death) who reffered to our center with breast cancer. Results: The median age was $49.2{\pm}14.2$ years (range 30-83 years). A family history of breast cancer was noted in four cases. The main clinical complaint was a retroareolar mass in 85.7%of patients (n=18). Histologically, 85.7% (n=18)were invasive ductal carcinoma and 4.7% (n=1) had ductal carcinoma in situ and 9.4% (n=2) had mixed histology including invasive medullary and ductal carcinoma. Hormonal therapy was delivered to 16 cases (76.1%) due to ER or PR positivity. During median follow up of 30 months (3-84 month), distant metastases were evident in 4 cases (19%). During the follow-up period, only one patient died due to metastatic disease. The mean time to recurrence detection was 30 months. Conclusions: The percentage of cases of male breast cancer is very low compared to breast cancer in females, explaining why very few investigations have been conducted in Iran. Limited coverage in the literature make gender-specific findings difficult so future research of this entity involving multi-institutional cooperation and longer follow up is essential to provide new insights about the biological and clinical factors of this rare cancer.
