The purpose of this study were to identify the financial status of the home based business, and to analyze the factors effected on it. The sample consisted of 713 self-employed from data of 1998 Korea Household Panel Study, and analyzed into Frequencies, Percentile, t-test, $\varkappa$$^2$-test, and Regression Analysis. The findings showed that the household income and expenditure level of female self-employed was higher than those of male self-employed. In case of financial status of business, male self-employed's net profit was higher than female's and the net profit to total sales ratio of male self-employed was greater than female's. The factors contributing to total expenditure to total income ratio were sex, educational level, future economic expectancy, residence and home ownership of self-employed, while the factor effect on total asset to total debt ratio was only total household income. The Variables of sex, educational level of self- employed, job type of home based business and the number of employees in home based business were associated with net profit to total sales ratio, age and educational level of serif-employed, and job type of home based business was related to total sales to the number of emploees ratio(labor productivity).

The purpose of the present study was to investigate craniofacial patterns in Korean male and female adults, and to compare morphologic differences between different facial types. In order to get configurational groupings, standardized lateral and P-A cephalograms of 174 Korean adults were measured and analyzed with seven angular, nineteen linear, four ratio, and two index measurements. Ward's minimum variance cluster analysis was employed to divide the sample into groups having similar craniofacial morphology, and thereafter, inductive statistics(t-test) was used to characterize morphologic differences of the divided groups. And also, Pearson correlation coefficients were calculated to assess correlation between the cranial dimensions and upper/lower anterior facial height(UAFH, LAFH) in each facial types for both male and female The results were as follows; 1. There existed sexual dimorphism in most of variables except SN-FH angle, palatal plane angle, facial axis angle, facial index, lower anterior facial height ratio and upper facial height ratio. 2. A brachycephalic headform ($0.84{\pm}0.05$) with leptoprosopic facial form ($0.92{\pm}0.05$) was appeared in male, and a mesocephalic headform ($0.86{\pm}0.06$) with leptoprosopic facial form ($0.92{\pm}0.04$) was exhibited in female. 3. Facial types in both male and female subjects were divided into two groups, Group A (mesoprosopic facial type) and Group B (leptoprosopic facial type). The morphologic differences between Group A and Group B were as follows: a. Cranial measurements including index, angular and linear measurements were not found to be different between Group A and Group B in both sexes. b. Increased UAFH, LAFH, and upper/lower anterior dental heights were exhibited in Group Bs of both male and female. c. In both male and female, ramus height and mandible length showed no difference between Group A and Group B. However, genial angle was found to be larger in Group B than Group A. Therefore, the morphologic differences between two groups in male and female were closely related to less favorable anatomic morphology of the mandible. 4. LAFH and UAFH showed no relationships with cranial dimensions in male and female.

This study was designed to investigate the median nerve cross-sectional area of the upper extremity which is the main cause of CTS in the 20s and 30s. The median nerve cross-sectional area (MNC-area) of each part of the upper limb was measured in healthy 20s and 30s females and males without neurological diseases or other diseases. This MNC-area was compared with the hand, wrist, finger, and other body indexes. The research group was divided into 20s female and male groups, and the 30s were also divided into female and male groups. In the comparison between the ages, the hand, and wrist configurations in the 30s were significantly higher than those of the 20s. The mean median nerve cross-sectional area was significantly larger in the male group than in the female group in both 20s and 30s, and it was larger in both men and women than in the 20s. Hand and wrist configurations were also positively correlated with the median nerve cross-sectional area in both 20s and 30s. The median values of hand ratio and wrist ratio were 2.26 and 0.65, respectively. This median value of hand ratio was inversely correlated with the median nerve cross-sectional area. The median nerve cross-area of the 20s was 6.88~7.38 ㎟ in the male group and 5.69~6.99 ㎟ in the female group, respectively. The median nerve cross-area of the 30s was 6.32~8.89 ㎟ in the male group and 6.15~7.17 ㎟ in the female group, respectively. The mean median nerve cross-sectional area was positively correlated with body mass index in both groups. Most of the variables were higher in their 30s than in their 20s.

The study examined nutritional conditions to enhance the quality of meals and to provide the basic data for more proper dietary life of college students. Our analysis was based on the body measurement, food intake and food habits for 200 students of Chung-Nam. The nutrient intake was examined using the 24-hour recall method. The data were analyzed by the Computer Aided Nutritional Analysis Program and then the diet quality was estimated using the Mean Adequacy Ratio(MAR), the Nutrient Adequacy Ratio(NAR) and the Index of Nutritional Quality(INQ). The average weight and height of male students were $67.57{\pm}8.66kg,\;174.64{\pm}5.87cm$, while those of female students were $53.46{\pm}6.86kg,\;159.10{\pm}4.19cm$, respectively. The total energy intake of the male students was $3221.71{\pm}200.39kcal$, while that of the female students was $1884.67{\pm}100.93kcal$. The male students are higher than female in % of RDA. The percentages of carbohydrate, protein and lipid for male students were $57.18{\pm}7.83%,\;15.15{\jpm}3.36%\;and\; 27.67{\pm}6.68%$, while those of female students were $58.77{\pm}7.68%,\;15.51{\pm}4.55%\;and\;25.72{\pm}6.20%$, respectively. There was no significant difference in calcium intakes for both groups, however they are less than the RDA. In terms of iron, the male students took $16.98{\pm}5.57mg$ and the female students took $11.35{\pm}2.68mg$, with significant difference (p<0.001). The male and female students showed sufficient intake of vitamins, with significant difference between two groups except for vitamin A. The mean MAR, an index of overall dietary quality, was significantly higher in the male students than female students(p<0.01). Male and female students enjoying two meals or more a day were 59%, and those having enough time for one meal or less a day were 36.5%. Male and female students having no breakfast were 39%. Male and female students having vegetables intake were 53.5%, and having milk or milk products every day were 29.5% of them. In conclusion, nutritional education is recommended to increase the calcium intake and fruit and vegetable consumption for dietary fiber, and to emphasize regularity of meal time.

This study was conducted to investigate the dietary behavior and health-related lifestyles of university students in Incheon arear Self administered questionnaires were collected ken 179 food and nutrition major and non-major students. Statistical data analysis was completed using a SPSS v.10.0 program. The results are summarized as follows: The average weight, height, BMI and PIBW of the major and non-major male and female students were 69.89kg, 172.89cm, 23.4 and 106.49 ; 67.27kg, 173.98cm, 22.2 and 101.35 ; 50.61kg, 161.20cm, 19.53 and 92.25 ; 53.77kg, 161.53cm, 20.56 and 97.18, respectively. The breakfast skipping ratio of the subjects were very high, which was mainly due to the reason“lack of time”More than 75% of male students and 61% of female students responded to have lunch at university canteens or restaurants around campus regularly. About 56% of male students and 68% of female students responded to have dinner irregularly, which mainly caused by the reasons“irregularity of lecture”and “appointment with friends”. The ratio of snacks intake of the subjects were high; Ramyun was the snack item taken the most by the male students and fruits and cookies by the female ones. More than 50% male students and 2% of female students were smokers. A half of students dunk alcohol once or twice a week. The dietary behaviors and health-related lifestyles between major and non-major male students tended to be very similar. The major female students showed more health-oriented dietary behaviors in comparison with the non-major ones. Therefore, they should have a major-oriented and practically organized nutritional education program to correct their dietary behaviors and health-related lifestyles fur health.

The study was designed to investigate the relationship between dietary intakes and the obesity of 400 students who were the third grade in middle school in some areas of Seoul. The survey conducted from March 3 to 13 , 1993. The results obtained were summarized as follows :The average height and weight of surveyed subject were similar to that of standard ( the third grade students in middle school in Seoul, 1991) . Compared to the standard weight/height ratio, subject who belonged to overweight and obese group were 16.4% of male students, 16.1% of female students respectively. Female subjects showed higher ratio than male subjects in skipping meals, frequency of snack per day and concern about a dieting . In case of subjects who belonged to weight /height ratio was high, their speed of dining was fast and they have more concern about a dieting. Compared to the amount of the nutritional intakes of RDA, calcium intakes of male and female subjects were deficient. Especially iron intakes of female subjects were deficient. In takes of Calorie (p<0.01) protein(p<0.05) and fat 9p<0.01) of obese group were higher those of non-obese group. Obese group showed good appetite and overeating also . Correlation analysis showed that obese group seemed to the closely associated with relative body weight of parents, family income, frequency of meals per day, frequency of meals per day, frequency of snack per day, speed of dining and overeating .

The quadrilateral analysis is a proportional analysis which evaluates the skeletal configuration of lower face on the relations between both jaws in the horizontal as we]1 as vortical dimensions. This study was undertaken to analyse the harmony and disharmony of quadrilateral patterns in normal occlusion and malocclusion. The present study was carried out on lateral cephalograms of 530 Korean children; the subjects consisted of 135 normal occlusions (63 male and 72 female), 105 Class II division 1 malocclusions (52 male and 53 female), 109 Class III malocclusions (50 male and 59 female), 91 hypodivergent facial types (44 male and 47 female) and 90 hyperdivergent facial types (45 male and 45 female). The following conclusions were reached: 1. Means and standard deviation in each group and sex were obtained from normal occlusion and malocclusion. 2. Quadrilateral mean diagram in normal occlusion was constructed for male and female, respectively. 3. In normal occlusion, 1:1 ratio exists between the maxillary base length (A' to Ptm') and mandibular base length (B' to J'), but lower facial height is targer than above. 4. Difference is effective to estimate the degrees of Class II and Class III malocclusion, and lower facial height (LFH) and sagittal angle is effective to recognize the hypodivergent and hyperdivergent facial type. 5. Quadrilateral analysis is able to visualize the anteroposterior and vertical dysplasia of lower face, and it is helpful to recognize certain problems in malocclusion.

Objective: The aim of this study was to investigate enuretic children attending oriental hospital and classify subtypes and evaluate possible factors that enhance or hamper of continence. Methods: Children attending kyeongju dongguk oriental hospital pediatrics between January 2000 and December 2003 with chief complaint of nocturnal enuresis were enrolled. The data of present symptoms and improvement progress was collected via telephone interviews with their parents. Results: The total number of children was 61. 32 of them were male and 29 female. Sex ratio was 1.1:1. Patient under 6 years of age was 68.8%. Using acupuncture, acupressure or chimsband with herb medicine, treatment frequency was increased. Patients with nocturnal enuresis(NE) was 48, and primary nocturnal enuresis(PNE) 39, secondary (SNE) 9. 13 was impossible to diagnose. The ratio of male to female was 1:1.09. PNE was 4 times as many as SNE. Male was predominent in PNE, and female in SNE. In the progress of PNE, male and female were similiar. but SNE, male was all cured, female remained 50%. And elapsed time of male to improve was longer than that of female. In the progress of improvement, many parents mentioned that their child was improved spontaneously regardless of subtype. Conclusion: We consider age, sex distinction, subtype, bladder symptoms, frequency, time of progress as influencing factor of prognosis, but failed to verify significance. To develop guideline of NE and find influencing factor of prognosis, more prospective study through taking history carefully and using questionnaire is needed.
