The purpose of this study was to investigate the effect of forest play activities on children's emotional vocabulary change. Forest play activities were conducted for 498 children aged 4 to 5 years old who visited the environmental training in G city for forest play activity for 1 hour. As a result, positive vocabulary was significantly improved from 0.95±0.78 before forest play to 1.15±1.21 after forest play(p=.003) and negative vocabulary was significantly decreased from 1.27±1.58 to 0.41±1.10(p=.000). In the case of male children, positive vocabulary was increased significantly from 0.96±0.82 to 1.36±1.24(p=.000), in the case of negative vocabulary, it decreased significantly from 1.42±1.74 to 0.55±1.30(p=.000). In the case of female children, negative vocabulary was significantly decreased from 1.12±1.37 to 0.26±0.26(p=.000), but the positive vocabulary increase was not significant(p=.851). As a result of age, for a 4-year-old children, positive vocabulary did not show significant difference between before and after forest play(p=.471), and negative vocabulary was significantly increased from 1.04 ± 1.42 before forest play to 0.41±1.16 after forest play(p=.000). For a 5-year-old children, positive vocabulary was increased significantly from 0.96±0.85 to 1.23±1.21(p=.001) and negative vocabulary was decreased significantly from 1.41±1.65 to 0.41±1.06(p=.000). As a result of this study, it was found that play activities using various natural objects in the forest were directly related to nature, resulting in positive vocabulary increase and negative vocabulary decrease.

Objective : This study aimed to examine the association between the structural and functional aspects of social networks and health-promoting behaviors in community-dwelling older adults. Methods : Social networks based on structural and functional aspects and health-promoting behaviors by lifestyle were measured in 226 community-dwelling adults aged 65 years and over. To analyze the collected data, an independent t-test, one-way ANOVA, Pearson's correlation analysis, and hierarchical regression were performed. Results : The network size was the highest in the friend network, and the frequency of contact and social support was the highest in the non-living family network. Health-promoting behaviors were highest for activities of daily living and lowest for productive and social activities. All subfactors of social networks showed significant positive correlations with health-promoting behaviors. Hierarchical regression showed social support from neighbors as the variable with a significant effect on health-promoting behaviors; gender and depression were also influencing factors, and this model showed 37% explanatory power. Conclusion : To promote healthy behaviors of older adultsin the community, the development of health promotion programs and related policies considering social networks centering on social support from neighbors is required.

This study was conducted to investigate the quality characteristics of seasoned pork prepared by Korean traditional 4 types seasoning such as soy sauce (T1); Kimchi sauce (T2); pickled shrimps sauce (T3) and onion sauce (T4). The samples were seasoned by the proportion of meat to seasonings (1:1). The seasoned samples were aged at $1{\pm}1^{\circ}C$ for 30 days. The results obtained were as follows; pH of T3 was higher (p<0.05) than other treatments during aging periods. Saccharinity and salinity were higher in T1. Except T3, water holding capacity (WHC) have no significantly (p>0.05) different during the aging. Shear force and Volatile basic nitrogen (VBN) were increased in T1 and T4 with aging periods. TBARS have no significantly (p>0.05) different in all treatments at the 1 day of aging, however T1 was significantly higher (p<0.05) compared with other treatments after 10 days of aging. In surface meat color, a* and b* were higher in T2 and lower in T4 with aging periods. In inner meat color, L* was decreased in all treatments with aging periods, however T4 was no significantly (p>0.05) different during aging periods. a* and b* were increased with aging periods in all treatments. Total plate counts was increased at the 10 days of aging and decreased at the end of aging. Escherichia coli of T1, T2 and T3 were decreased with aging periods, however T4 was significantly (p<0.05) increased with aging periods. Lactobacilli spp. of T2 and T3 were higher than other treatments at the beginning of aging. In sensory evaluation, T4 was higher at the beginning of aging, however T1 and T3 were increased sensory evaluation value with aging periods.

We evaluated the association between sleep duration, dental caries, and periodontitis by using representative nationwide data. We examined 8,356 subjects aged ${\geq}19$ years who participated in the sixth Korea National Health and Nutrition Examination Survey (2013~2014). Sleep duration were grouped into ${\leq}5$, 6, 7, 8, and ${\geq}9$ hours. Presence of dental caries was defined as caries in ${\geq}1$ permanent tooth on dental examination. Periodontal status was assessed by using the community periodontal index (CPI), and a CPI code of ${\geq}3$ was defined as periodontitis. A chi-square test and multiple logistic regression analysis were used to determine statistical significance. Model 1 was adjusted for age and sex, model 2 for household income, educational level, and marital status plus model 1, and model 3 for smoking status, alcohol consumption, blood pressure level, fasting blood glucose level, total cholesterol level, and body mass index plus model 2. The prevalence of dental caries according to sleep duration showed a U-shaped curve of 33.4%, 29.4%, 28.4%, 29.4%, and 31.8% with ${\leq}5$, 6, 7, 8, and ${\geq}9$ hours of sleep, respectively. In the fully adjusted model 3, the risk of developing dental caries was significantly higher with ${\leq}5$ than with 7 hours of sleep (odds ratio, 1.23; 95% confidence interval, 1.06~1.43). The prevalence of periodontitis according to sleep duration showed a U-shaped curve of 34.4%, 28.6%, 28.1%, 31.3%, and 32.5%, respectively. The risk of periodontitis was significantly higher with ${\geq}9$ than with 7 hours of sleep in models 1 and 2, whereas the significant association disappeared in model 3. In a nationally representative sample, sleep duration was significantly associated with dental caries formation and weakly associated with periodontitis. Adequate sleep is required to prevent oral diseases such as dental caries and periodontitis.

Purpose: The purpose of this study was to investigate the effects of hypertension relevant nutrition knowledge on practices for prevention of hypertension in Chinese college students studying in South Korea. Methods: We conducted a survey of 276 Chinese students studying more than three months in Korean universities who were aged 19 and older about hypertension and sodium relevant nutrition knowledge, intake of salty processed food, hypertension prevention practices, and stages of behavior change for hypertension. Results: The average score on the questionnaire for hypertension relevant nutritional knowledge was 40.62 out of 50 points, and the average score for sodium relevant nutritional knowledge was 24 out of 30 points. Kimchi was the most frequently eaten salty processed food. The average score for hypertension prevention practices was 3.10 out of 5 points. The behavior change stages for prevention of hypertension were contemplation (47.1%), action (32.2%), and pre-contemplation (20.7%). The students received high scores on nutrition knowledge and showed significantly higher scores on the action stage than on pre-contemplation or contemplation. Nutritional knowledge of hypertension and sodium showed positive correlation with hypertension prevention practices, whereas negative correlation with salty processed food intake. Conclusion: Development of an education program for Chinese students in Korea on hypertension and sodium relevant nutritional knowledge is needed so that they can practice for prevention of hypertension.

Background : To characterize the clinical features and determine the prognostic factors of severe community-acquired pneumonia. This study is the first of its kind in Korea. Methods : Recruited were 40 patients diagnosed as severe community-acquired pneumonia in Hallym University Hospital from January 1, 1989 through July 31, 1996. Patients were analysed retrospectively for age, sex, underlying disease, respiration rate, hypoxemia, requirement of mechanical ventilation, involvement on chest radiograph, shock, and the serum concentration of BUN and albumin. All parameters were compared between survived and dead group. Results : Male to female ratio was 2.07 : 1. The mean age was $63.1{\pm}17.5$years(range 25~90years) with 65% of patients aged equal to or more than 60. The major underlying diseases were old pulmonary tuberculosis(12.5%), chronic obstructive pulmonary disease(7.5%), bronchial asthma(5%), bronchiectasis(2.5%), and diabetes mellitus(22.5%). Microbiologic diagnosis was made in 26 out of 40 patients(65%). The most common causative organism was S. pneumoniae(17.5%, 7/40) followed by S. aureus(15.0%, 6/40), K. Pneumoniae(12.5%, 5/40), M. tuberculosis(7.5%, 3/40), H. influenzae(2.5%, 1/40), coagulase negative staphylococcus(2.5%, 1/40), P. aeruginosa(2.5%. 1/40), E. cloaceae(2.5%, 1/40), and E. coli(2.5%, 1/40). M. pneumoniae was detected in no patient. The most frequent drugs administered in single or combination therapy were aminoglycosides(75%, 30/40), second- and third-generation cephalosporin(40%, 16/40 and 27.5%, 11/40), macrolides(27.5%, 11/40), and amoxicillin/clavulanic acid(22.5%, 9/40). Of the 40 patients, 14 died of severe community-acquired pneumonia(37.5%). Among them, seven patients (50%) expired within 72h of hospital arrival. According to multivariate analysis, mortality was significantly associated with requirement of mechanical ventilation, bilateral pulmonary involvement, and serum albumins$\leq$3.0g/dl. Conclusion : An understanding of the clinical characteristics and prognostic factors in severe community-acquired pneumonia identified in this study will optimize therapeutic approach in this disease and help decreasing its notorious mortality rate.

Purpose : In order to evaluate the value of the renal expression of ICAM-1 as a marker of renal injury, we analyzed the relationship between abnormal tubular expression of ICAM-1 and histopathological features and clinical manifestations in children with IgA nephropathy (IgAN). Methods: The clinical data from 43 patients with IgAN were analyzed retrospectively and compared to the histopathologic subclassification proposed by Haas. ICAM-1 in tubular epithelium was assessed using the LSAB(Labeled streptavidine biotin) kit on the renal biopsy specimens. Results: In 43 patients with primary IgAN, 28 males and 15 females aged $12.2{\pm}2.2$ years were studied. There were no differences of renal tubular expression of ICAM-1 between patients with gross hematuria and without gross hematuria. But renal tubular expression of ICAM-1 in patients with proteinuria was significantly higher than that of in patients without proteinuria($78.2{\pm}14.19%\;vs\;55.8{\pm}32.20%,\;P<0.05$). Renal tubular expression of ICAM-1 was also associated with the severity of histopathological degree using Haas classification method. In subclass I, renal tubular expression of ICAM-1 was significantly lower than those of other subclasses. A significant correlation was found between the tubular expression of ICAM-1 and the total amount of protein in 24 hour collected urine$(r_s=0.47236,\;p<0.05)$. But there were no significant correlations between the renal tubular expression of ICAM-1 and interstitial cellular infiltration, tubular atrophy, and interstitial fibrosis respectively(F=0.89, P>0.05; F=0.31, p>0.05; F=0.21, p>0.05). Conclusion: Renal tubular expression of ICAM-1 can be a useful marker of renal injury in children with IgAN. (J Korean Soc Pediatr Nephrol 2004;8:149-158)

Measles outbreak in the world was decreased since measles vaccine had been introduced. Although vaccination rate is high, measles was not eradicated and measles reappeared among vaccinated children. We measured measles-specific antibody from the vaccinated and unvaccinated groups who had experienced apparent measles in the Seongnam city in 1993. The results were as follows. 1) The data included total 126 children (M:F=1 : 1). Age distribution of measles outbreak revealed 6 children in 5yr, 11 in 6yr, 20 in 7yr, 39 in 8yr, 22 in 9yr, 11 in 10yr, 11 in 11yr, and 6 in 12yr. 2) MMR vaccination rate was 78.6%(99/126) in the children who had experienced measles. Positive rate of measles-specific IgM Ab was 80.8% (80/99) among the vaccinated group and among 9E.6.% (25/27) the unvaccinated. 3) Positive rate of measles-specific IgG Ab was 90.9% (90/99) among MMR-vaccinated group, and 85.2% (23/27) in unvaccinated group. In conclusion, measles-specific IgM antibody have been detected more than 1 month in most patients. The relatively high proportion of measles-specific IgM positivity may mean primary vaccine failure. To booster the antibody titers and to prevent measles epidemic in school-aged children, revaccination of measles should be considered.

Background: With the increasing age of the population, coronary artery bypass grafting in the elderly patients is becoming common. Off-pump coronary artery bypass grafting (OPCAB) has been proven to be less morbidity and to facilitate early recovery. The elderly patients may have benefits by avoiding the adverse effects of the cardiopulmonary bypass. The purpose of this study is to evaluate our results of OPCAB in elderly patients. Material and Method: A retrospective chart review was carried out for 12 patients aged over 80 years who underwent isolated OPCAB from January 2001 and March 2004. Data were collected risk factors for disease, extent of coronary disease, and in-hospital outcomes. Postoperative graft patiency was evaluated in 9 patients by multi-slice computed tomography. Result: Eleven patients had triple vessel disease or left main disease. Four patients were suffered from preoperative CVA, and 4 patients had chronic obstructive pulmonary disease. Two patients had myocardial infarction (MI), among them 1 patient was suffered from pulmonary edema after preoperative MI. There was no perioperative death, perioperative MI, and no ventricular arrhythmia. Also there was no perioperative stroke and renal failure. But there was one deep sternal infection who recovered by treating of muscle flap. Atrial fibrillation was newly developed in 1 patient, but was well controlled by medication. Mean intubation time was $15.9\pm4.4(8\~20hrs)$ hrs and mean ICU stay was $2.9\pm0.8(2\~4 days)$ days. Mean hospital day was $21.6\pm14.3(13\~56 days)$ days. Postoperative mean CK-MS was $11.3\pm14.1\;ng/mL$. Early postoperative graft patency rate was $100\%(24/24)$. Follow-up was completed in all patients. In this time, there was no patients with angina or death. Conclusion: The results of this study suggest that OPCAB reduces morbidity and favors hospital outcomes. Therefore, OPCAB is safe, reasonable and might be preferable operative strategy in elderly patients.

A controlled and double blinded trial was performed to evaluate the effects of OPE supplementation on blood circulation in healthy male smokers. The study population consisted of 92 healthy male smokers aged $44.4{\pm}7.8$ years. The supplement group (n=49) received OPE containing 100 mg quercetin/day for 10 weeks, while the control group (n=43) received placebo powders. The prothrombin time and activated partial thromboplastin time increased significantly after OPE consumption, indicating the attenuated blood clot formation by OPE. In conclusion, these results indicate that the daily consumption of OPE (containing 100 mg quercetin) for 10 weeks exerts significant health benefits through the modulation of physiological functions including the blood circulation in male smokers.
