The purpose of this study is to ascertain the actual conditions of volunteering activities in respect to age-integrated leisure. This study is based on the 2010 Korea Leisure Life Survey. The participants in this study were 3015 people who reside in Korean cities, except for Jeju-do. Questionnaires from the 2010 Korea Leisure Life Survey were used for the final analysis. Data were analyzed through a descriptive analysis, Chi-Square test and ANOVA by SPSS WIN 17.0. The findings indicated that 18% of the participants participated in volunteer activities as leisure in the last one year. The major findings were as follows. First, demographic characteristics such as age, academic career, income, and marital status had a positive correlation with the degree of volunteer participation. Second, there were differences in duration and field of activities according to age. Third, though most of the non-volunteer reasons were 'lack of resources', there were different reasons based on age. In detail, the reason for 10-50 year-olds (economically active population) was 'lack of time', but the more than 60 year-olds was 'health concern'. Consequently, this access to the life cycle study shows the need to improve life satisfaction.

Long-term effects of Ganoderma lucidum (GL) on memory and oxidative stress of senescence-accelerated mice (SAM) were investigated. Senescence-resistant (R1) and prone (P8) strains of SAM were fed GL diets, premixed with low (20 mg/kg/day, T1) or high (200 mg/kg/day, T2) levels of GL powder for 9 months starting from young (3 months of age) or for 5 months starting from old (7 months of age). After the final feeding at 12 months of age, all animals were subjected to passive avoidance test for the evaluation of memory function. In addition, the changes in hepatic thiobarbituric acid-reactive substance (TBARS) and glutathione were analyzed. SAMP8 fed GL diets from old age (7 months) exhibited the improvement of memory, although GL rather inhibited the memory function of both SAMR1 and SAMP8 mice fed diets from young (3 months of age). Hepatic TBARS contents were decreased in SAMP8 fed high GL diet for 9 months and in SAMR1 fed low GL diet for 5 months. Hepatic glutathione content was also remarkably increased in SAMR1 following both feeding periods, and less extent in SAMP8 fed diet for 5 months of age. Taken together, it is proposed that GL extracts may play an anti-aging role through antioxidant action, and thereby may improve the senescence-related memory dysfunction.

Purpose: Abdominal pain is the most common symptom of patients visiting the emergency department (ED). Abdominal pain is caused by a variety of causes, so it is difficult for a triage nurse to determine the urgency of a patient, but it is still a must. The purpose of this study was to identify the related factors to the urgent diseases of patients with abdominal pain visiting ED. Methods: This study was a retrospective descriptive study. The study setting was an ED in a tertiary hospital in Korea. Data were collected from September 1, 2017 to October 15, 2017. During the study period, of a total of 6,181 patients visiting the ED, 731 complained of abdominal pain. Patients with obvious cause of pain and patients who could not express detailed symptoms were excluded. The 573 patients were included in the final analysis. We collected demographics, clinical characteristics, and final diagnosis. We divided final diagnoses into urgent diseases which were more likely to be life-threatening without treatment and non-urgent diseases. We identified the related factors to the urgent diseases of patients with abdominal pain using the logistic regression. Results: 173 (30.2%) patients had urgent diseases. Age (OR=1.02, 95% CI=1.00~1.03), referral from other clinics (OR=2.92, 95% CI=1.86~4.60), ambulance utilization (OR=2.00, 95% CI=1.27~3.15), diarrhea (OR=0.44, 95% CI=0.25~0.76), and tachycardia (OR=2.27, 95% CI=1.44~3.58) were related to urgent diseases. Conclusion: Triage nurse should take into account the patient's age, mode of visiting, and route of visiting ED; and check the symptom of tachycardia or diarrhea.

Purpose: Our goal was to determine the difference in motor recovery between two stroke types: the corona radiata (CR) infarct type and the intracerebral hemorrhage (ICH) type, by using assessment methods for motor functions. Methods: Forty subjects who were diagnosed as having had a stroke with an infarct (men: 11, women: 9, mean age: $62.25{\pm}7.59$) or a stroke with an ICH (men: 12, women: 8, mean age: $59.75{\pm}6.11$) were recruited. In all subjects, motor functions of the affected extremities were measured 2 times: at stroke onset (initial) and 6 months after the onset (final) by the motricity index (MI), the modified Brunnstrom classification (MBC), and functional ambulatory category (FAC). We compared the final assessment with the initial one. Results: Motor functions of all patients improved with the passing of time. All scores of motor function assessment in the ICH type were higher than in the infarct type. Comparing the initial assessment with the final one, upper MI and MBC scores of the upper extremities were significantly different between the two stroke types (p<0.05), but lower MI and FAC scores of the lower extremities were not (p>0.05). Conclusion: These findings imply that patterns of motor recovery in patients with either the infarct type or the ICH type of stroke change for the better over time. The degree of motor recovery in the ICH type was better than in the infarct type. Therefore, one can introduce clinical interventions by the aspect of progress in functional motor recovery.

Objectives The purpose of this study is to find out the relationship between mid parental height (MPH), birth weight, current growth condition of children (height, weight, BMI, body fat percentage, bone age) and final height of the future. Methods The study was conducted with 237 children, who were 12 - 14 years old. They were analyzed to find out the relationship between MPH, birth weight, height, current weight, BMI, body fat percentage, bone age and predicted height. Results 1. As MPH was increased, height and predicted height were also increased. As MPHs in girls were increased, 'bone age - chronological age' were decreased. As MPHs in girls were increased, body fat percentages were decreased. 2. As birth weights were increased, height, weight, BMI and body fat percentages were also increased in boys. 3. As body fat percentage was increased, predicted height was decreased. As 'bone age - chronological age' was increased, predicted height was decreased. As BMI was increased, 'bone age - chronological age' was increased. As body fat percentages in boys were increased, heights were decreased. As body fat percentages in girls were increased, 'bone age - chronological age' were increased. Conclusions MPH, birth weight, current growth condition (height, weight, BMI, body fat percentage, bone age) and predicted height are correlated to each other. There are some differences between boys and girls in these relationships.

The purpose of this study was to identify the risk factors affecting home care patients 65 years of age and older with symptoms of depression. The author conducted this study for 80 depressed and non-depressed who were taking home care. Data was colleted from November 1996 to October 1997. The major findings of this study were as follows. Significant mean group differences were found on age and income in old home care patients with symptoms of depression, compared with non -depressed. Old home care patients who have less than 300,000won of income, smoking, exercise, unsatisfactory of home care, living in saparateness, rent, living alone, unbalanced diet, irregular diet were statistically significant risk factors by logistic regression. Old home care patients who do not exercise, less than 300,000won of income, unsatisfactory of home care, smoking, living alone were the risk factors by final logistic regression model predicting depression.

Background and Objectives In this study, we evaluated differences in the prevalence of allergic rhinitis, asthma, atopic dermatitis and specific immunoglobuline E (IgE) value for some respiratory antigens in Korean adults. Subjects and Method The study was conducted using data from the 5th National Health and Nutrition Survey (2010-2012). All subjects who were aged 19 years or older completed questionnaires on asthma, atopic dermatitis and allergic rhinitis. The subjects were first divided into male and female, and then into age groups of 19-29, 30-39, 40-49, 50-59, 60-69, ${\geq}70$ each. The lifetime and current prevalence rates for allergic rhinitis, asthma, and atopic dermatitis were calculated for each age group. The total and specific IgE level for Dermatophagoides farinae (DF), cockroach, and dog dander were also calculated. Results Final participants of 17542 were analyzed for the prevalence rate among the total of 25534 participants. The mean IgE level was calculated from 2028 subjects from the final participants. In asthma, the lifetime prevalence and current prevalence increased with age, but decreased with atopic dermatitis and allergic rhinitis. Total IgE level increased with age, but IgE level of DF reached its peak at 20-29 years, and then decreased rapidly thereafter. There was no clear trend for cockroach and dog dander. Conclusion The prevalence of allergic diseases in adults varies widely by age group. Asthma has a low prevalence after age 20 and gradually increases after age 50. Atopic dermatitis and allergic rhinitis are the most prevalent in their 20s and gradually decrease thereafter.

Two rational formulae depicting the relationships between sludge ages and recycle flow rates have been developed to determine sludge wasting volumes at a particular sludge age. A sensitivity analysis shows that the recycle ratio is the most important variable to be measured as accurately as possible in determining the sludge wasting volume to maintain a particular sludge age when the system is controlled by wasting recycled sludge. On the other hand, the final clarifier solids capturing capacity is the most important variable to be measured when the system is operated by wasting mixed liquor.

This experiment was carried out to determine the effect of pure mineral nitrogen fertilization on dry matter yield and the amounts of advisable mineral nitrogen on grassland according to its age at the "Federal Institue for Agriculture in the Alps" in Austria. The results obtained were as follows: 1. With only PK-fertilizing average dry matter yields per year were progressively declined during the period of the studies. Compared with the relatively younger grassland(1st-5th year) the DM-yields were decreased by 35% in older grassland (11th-final year). 2. Due to the less reduction of DM-yields by mineral nitrogen application according to the age of grassland. With N-fertilizing the reduction of DM-yields in relatively older grassland was less than that of younger grassland by 11-21%. 3. At 4-and 5-cut systems the nitrogen amounts for the highest marginal yield(the "most efficient" Ndressing rate) per ha and year were distinctly declined in the relatively older grassland. 4. Required efficiencies of mineral nitrogen were not influenced by the age of grassland.he age of grassland.

The aim of this study was to determine the effects of breeder age and stocking density on performance, carcass characteristics and some stress parameters (H-L ratio, serum glucose, cholesterol and triglyceride levels, tonic immobility test (TI), antibody production, relative asymmetry (RA) and external appearances). This experiment was carried out with 705 one-day old male broiler chicks (Ross 308) obtained from three different ages of broiler breeder (32, 48 and 61 wks). Each age group was randomly divided into two stocking density groups (11.9 and 17.5 broilers per $m^2$) with 5 replications per group. The experimental period was 6 weeks. Broilers from 32 wk-old breeders had lower initial weight (p<0.001), body weight gain of the first 3 week of rearing (p<0.01), the percentage of abdominal fat (p<0.001) and serum cholesterol level (p<0.01); higher percentage of gizzard (p<0.01) and longer TI duration (p<0.001) than those from 48 and 61 wk-old breeders. Broilers reared at 17.5 b/m2 had lower final BW, body weight gain, feed consumption, feather condition and foot health (p<0.001), higher percentage of heart, H-L ratio, serum glucose and cholesterol levels (p<0.001), and longer TI durations (p<0.001). There were no significant interactions in examined parameters except for feed to gain ratio between breeder age and stocking density.
