This study investigated the influence that the family rituals of unmarried males and females have on satisfaction with life and family role salience, recognizing the necessity to illuminate perceptions related to the original families of unmarried males and females through more diverse perspectives. Questionnaires were given to 601 unmarried male and female adults over 20 years of age. For data analysis, SPSS Win 18.0 was used, and the results are summarized as follows. First, the males and females were divided into three groups: "family with inactive family rituals", "family with active family rituals" or "family with moderate family rituals". There was a significant difference in family role salience depending on family type. Second, family type was classified as a degree of "relation" through common points of two variables, and each group was named as having a family with "satisfying relations," "general relations," or "deficient relations." Third, in the case of males, life satisfaction was high when the level of family economy was high, when parents' first marriage and family actively participated in family rituals.

This study was conducted to find the gender and age differences in dietary behaviors and food consumption pattern of Korean American adults living in western parts of USA. The structured survey forms and self-administered food frequency questionnaire were used to assess dietary behavior and nutrient intakes. It was found that younger subjects kept their meal time more irregularly and skipped breakfast more often than older subjects due to lack of time. There were significant age differences in skipping meals, kind of skipping meals, and the reasons for skipping meals. Young subjects consumed more American type food while older subjects consumed more traditional Korean food. Nutrient intakes of males' except for the elderly were significantly higher in energy, protein, Fe and P than those of females'. Vitamin A and vitamin C intake were significantly higher in females. Energy ratio of carbohydrate: protein: fat was 56.2 : 16.8 : 27.0. Females consumed more plant food as their dietary sources of protein, fat, Ca and Fe, compared to males. Ca intakes of participants' were below $75\%$ of RDA except for the youngest male and $30\~49$ aged male and females. Futhermore, Ca intake was below $70\%$ after age 50 in both genders. Effective nutrition education program targeting Korean Americans in the community should be developed and implemented to increase Ca consumption.

This study aims to analyze the relative importance of bone age and chronological age in physique according to gender and to identify the relative importance of bone age, chronological age, and physique in physical fitness and motor coordination according to gender in order to alleviate the imbalance between physique and physical fitness in children. A total of 666 children(346 males, 320 females) between the ages of 11-14 were enrolled as subjects, and the skeletal maturation The skeletal maturation were measured by taking hand-wrist. Physical fitness were measured through a total of 4 components: muscular strength. The results of this study. First, physique variables for both males and females aged 11-14 were found to be more significant predictors of bone age than chronological age. Second, for physical fitness in males, in the order of %fat, body water, waist-hip ratio, weight, fat-free mass, and chronological age were more significant predictor variables; and in females, in the order of %fat, fat-free mass, height, chronological age, weight, bone age, fat mass, and body water were more significant predictor variables. For bone age and chronological age in physical fitness, bone age in males and chronological age in females found to be the more representative variables respectively.

Background: Although warm-ups before exercise are widely accepted, research on sex differences in improving hamstring flexibility is limited. Differences in the physical and physiological characteristics between males and females may result in different responses to warm-ups. Objects: This study aimed to examine sex differences in the effects of specific warm-up on hamstring flexibility. Methods: This study included 24 young adults with hamstring tightness. The participants performed five maximal knee extensions and flexions at 90° flexion of the hip, and the maximal knee extension angle was measured in real-time using a smartphone clinometer application. Results: The groups did not significantly affect the maximal knee extension angle but showed a significant effect for repetition (p = 0.002) and group-repetition interaction (p = 0.002). Males had no significant change in hamstring flexibility; however, females showed a significant increase in flexibility in the 5^th trial compared with the 1^st trial (p = 0.041). These results demonstrated sex-specific differences in flexibility improvement over time. Conclusion: The findings of this study suggest that specific warm-up can successfully improve hamstring flexibility in females. This may be due to various factors, such as muscle stiffness of the lower extremity, estrogen levels, and temperature sensitivity. In clinical settings, specific warm-up might be helpful for females who participate in sports or activities, such as running or jumping, which require a full range of motion in the hip and knee joints.

The chemical components, lipid class, and fatty acid composition of muscle from male and female common squid, Todarodes pacificus, were examined to evaluate the potential utilization of muscle from fin, head, arms, and tentacles, which consumers usually like less than the mantle. The mantle was found to constitute 47-49% of the total muscle and the proportion was slightly higher in females than in males. For the remaining 51-53% of the muscle, the only gender difference was that the arms of males contained approximately 3% more muscle than those of females (P<0.05). The protein content was higher in the mantle, arms, and tentacles than in the fin and head in both males and females (P<0.05), and was slightly higher in males (15.7-20.7%) than in females (15.1-19.2%). By contrast, the lipid content was slightly higher in females (1.82-2.54%) than in males (1.01-2.37%), and the fins in both males and females contained the most lipids (2.37-2.54%) of all muscle. The prominent lipid classes in the muscles were free sterol (males 81.5-91.9% vs. females 84.9-91.8% for the non-polar lipid content), phosphatidylcholine (PC, males 59.3-62.4% vs. females 49.2-57.8% for the phospholipid content) and phosphatidylethanolamine (PE, males 22.0-28.8% vs. females 25.6-33.8% for the phospholipid content). The percentage of PC was approximately 5-10% higher in males (P<0.05), especially in the fin, while that of PE was approximately 3-5% higher in female (P<0.05), especially in the head. All of the squid muscle contained 52.1-54.9% of n-3 polyunsaturated fatty acids (PUFA), such as docosahexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Males contained slightly more DHA, whereas female contained more EPA. The total percentage of n-3 PUFA differed little among muscles within the same gender.

Acute appendicitis is one of the most common diseases of young people that requires emergency operation. This is especially true for those age 10 years old and older. However, the numbers of cases of appendicitis are increasing in both the young and the elderly. The main purpose of this study is to understand the clinical features of acute appendicitis in children and elderly patients. We retrospectively compared clinical characteristics in 4 groups of patients who underwent appendectomy in our hospital. There were 16 patients in the pre-school age group, 9 were males and 7 females. The total number of patients in the juvenile group were 287, 156 were males and 131 females. The total numbers of patients in the adult group were 794, 436 were males and 358 females. The numbers of elderly patients were 189, 91 were males and 98 females. Complicated appendicitis was found in 15 patients (93.7 %) in the pre-school age group, 79 patients (27.5 %) in the juvenile group, 332 patients (41.8 %) in the adult group, and 96 patients (50.7 %) in the elderly group. Four patients (40 %) had generalized panperitonitis in the pre-school group. The occurrence of perforated appendicitis was the highest in the pre-school age group and the lowest in the juvenile group. Since generalized panperitonitis has a higher incidence in the pre-school age group, prudent and careful diagnosis and treatment are required for the pre-school age group.

Objectives Visual inspection is the first diagnostic method in Oriental medicine, and visual inspection of eyes is the one among them. This study was written in order to complement further understanding on visual inspection of eyes. Methods 1. Out of 102 photographs submitted to the Society of HyungSang Medicine in 2009, 27 portrait pictures were selected as samples in blind by 2 clinicians. The samples were copied to make 54 sample pictures, and then randomly assigned to 4 clinicians. 2. The 4 clinicians evaluated the 54 samples for excess and deficiency of the eyes. The results were recorded as 5-points-scale, and their average and standard deviation was calculated. 3. Intra and inter class reliability test were measured using SPSS 13. Results For intra- and inter-class correlation coefficient (ICC) values were measured as 0.654~0.967 and 0.756~ 0.783 respectively, with the P-value below 0.05. Out of 27 originally selected samples, 7 pictures were selected as Deficiency Samples (with 3 pictures of male and 4 of females), and 20 as Excess Samples (with 4 of male and 16 of female). Among them, Sample No. 1, 9, 22, and 26 were selected as models of 'Excessive Eyes' for females, no. 4 and 5 as 'Very Excessive Eyes' for male and females, and no. 15 as 'Moderate Eyes' for females. Conclusion This study is the first attempt of quantitative measurement of excess and deficiency using the Visual Inspection of eyes by the visual inspection experts. Still, additional studies are needed regarding the relationship visual inspection methods have with existing standards of diagnosis.

The purpose of the study was to examine the changes of food and nutrient intakes of college students between 1999 and 2009. Dietary survey of 169 college students was conducted by a 24-hour recall method for three days in 2009. Food and nutrient intakes in 2009 were compared with the data from 106 students collected by the same methods in 1999. The intakes of cereals & grain products and vegetables in 2009 were lower than those of 1999, but the intakes of meats, eggs, milk & milk products, and manufactured food were higher. The intake of rice per person decreased greatly from 452.2 g in 1999 to 351.4 g in 2009 in males, and from 306.9 g to 237.2 g in females. While the intakes of protein, fat, thiamin, niacin, vitamin $B_6$, phosphorus, potassium, zinc, and cholesterol were significantly higher, the intakes of dietary fiber were significantly lower in 2009 compared to 1999 both in males and females. The nutrients consumed less than the Recommended Intakes were vitamin A, riboflavin, vitamin C, and calcium in males and additionally folate, iron, and zinc in females in both 1999 and 2009. The ratio of carbohydrate, protein and fat as energy was 61 : 15 : 24 and 60 : 14 : 26 in 1999, and 54 : 16 : 30 and 56 : 15 : 29 in 2009 in males and females respectively, showing that carbohydrate intake decreased and fat intake increased greatly. Our data suggest that nutrition education is necessary for college students to help them consume more vegetables and fruits and less fat and cholesterol.
