Physical activity of the people has decreased due to a sedentary lifestyle according to developing the economy throughout the world. It is thought to increase the risk of chronic diseases, including obesity, diabetes, etc. People are interested in walking, which is an easy activity to engage in as an antidote to chronic diseases. The aim of this study is to increase the diminishing physical activity of modem society by inducing walking as part of everyday life through building a walking-based activity-friendly city where people can live merrily, safely and pleasantly. For this purpose, this study conducted a satisfaction survey to dwellers of Jinhae on the physical pedestrian environments which affect determining walking participation and intentions of people, and also provided a valid model to evaluate the effects of the physical environmental factors on walking satisfaction using factor analysis and multiple linear regression analysis. The results are summarized as follows. The 18 variables of the physical pedestrian environments were selected based on pre-literature reviews. The results of the satisfaction surveys showed that the satisfaction of crossing aids in segments was highest, while the building feature was the lowest. Factor analysis was run through a two-step process. The first analysis was conducted to examine the adequacy of this factor analysis on the selected 18 variables. As a result, two variables were removed and the remaining 16 variables were extracted to the four factors by second analysis. Each factor was named function of path, effect of traffic, amenity and safety based on the each factor's commonality. Each factor score of the extracted four factors was set as the independent variable, while the overall walking satisfaction was set as the dependent variable. Then, the multiple linear regression analysis was conducted and showed that all four factors had a positive influence on the overall satisfaction of walking, especially the 'function of path' and 'amenity' factors, followed by 'effect of traffic' and 'safety'. The results of this research will be used as foundational data for creating a walking-based activity-friendly city.
Objectives : Prevalence of postpartum depressive disorders reaches approximately 10-15% of childbearing women. This preliminary study was intended to explore the relationships between postpartum depressive disorders and family adaptability and cohesion. Methods : Childbearing women(n=24) were assessed for risk factors for postpartum depression before and after childbirth prospectively. At gestational age between 36th and 40th week, the questionnaire about various factors before childbirth, Edinburgh postnatal depression scale(EPDS), Family adaptability-cohesion evaluation scale (FACES), and Beck anxiety inventory(BAI) were assessed. After childbirth, for the diagnosis of postpartum depressive disorders, a structured diagnostic interview according to MINI International Neuropsychiatric Interview was performed, furthermore, the questionnaire about various factors after childbirth, EPDS, and BAI were assessed at 4-6 weeks postpartum. Results : Among various factors and scales, family adaptability and cohesion, mood symptom and change during pregnancy were associated with postpartum depressive disorder in comparison with non-postpartum depressive disorder subjects. In addition, low family adaptability and cohesion and mood change during pregnancy were significantly associated factors with postpartum depressive disorder using logistic regression analysis. Conclusion : The results suggest the postpartum depressive disorder could be related with prenatal low family adaptability and cohesion. This preliminary study, however, includes only a few subjects, so that further large-sized study will be needed to replicate our results.
This study was performed to investigate anti-thrombogenic, anti-inflammatory effects of n-BuOH (B) and $CH_2Cl_2$ (MC) fractions extracted from Sancho (Zanthoxylum. schinifolium) leaves in rats fed high fat diets. The experimental animal groups were consisted of eight including one 5% fat (N) and one 20% fat (H) without the test materials in diets and six H groups of feeding three levels (50, 100 and 150 mg/day) of the B and the MC fractions from Z. schinifolium, respectively. Plasma activated partial thromboplastin times and thrombin times of H group were decreased compared to the N group, but they were increased by feeding the MC fraction of 50 mg and over. Polymorphonuclear leukocyte 5#-lipo-xygenase activities and leukotriene $B_4$ contents of the H group were significantly increased compared to the N group, but they were decreased in the 100 mg and 150 mg of B fraction or the 150 mg of MC fraction fed groups. Liver cytochrome $P_{450}$, $O_2^-$, $H_2O_2$ and GSSG contents were increased by the high fat diet but decreased by feeding the B fraction or the MC fraction, while GSH content and glutathione S-transferase activity lowered by high fat diet were increased by feeding the two solvent fractions. The effects of the solvent fractions were evident at the level of 100 mg/day and over. The present results confirmed that two solvent fractions from the leaves of Z, schinifolium have enhancing effects on anti-thrombosis and anti-inflammation partly by antioxidant action and partly by direct modulation of the respective processeds. In conclusion, the n-BuOH and $CH_2Cl_2$ fractions from leaves of Z, schinifolium can be utilized as the proper ingredients of functional foods for preventing chronic degenerative disease.
Leptin, as an adipocyte-derived hormone, is an important regulator of food intake and energy expenditure. In the cross-sectional study, leptin was shown to be positively related to body adiposity and metabolic disorders in adults. However, there were very few studies which reported the leptin as a predictor of weight gain over time. We examined whether serum leptin can be used as an indicator of the present and 1-year past weight status in very young children. First grade students from elementary schools in Gwacheon City were enrolled in the study since 2005. The study subjects(total 375 students; 195 boys and 180 girls) participated in the investigation of both 2005 and 2006. Physical examinations including height, weight, waist circumference were done. To examine the prevalence of obesity, obesity index was used. Serum leptin was measured, and their nutritional status was also evaluated based on 3-Day dietary records. Serum leptin levels were strongly positively related with the value of the present BMI and with the value of the BMI one year before. We found no association with leptin levels and amount of energy intake and macronutrient intake in this children population. Children were divided into three groups according to leptin tertiles. The highest leptin tertile group showed highest prevalence of obesity in year 2006 as well as in year 2005. Serum leptin levels can reflect the weight status now and as well as 1-year before. Possibly serum leptin levels can predict the weight gain of year later. Without an action against the obesity on children with high leptin level, those children would maintain the excess adiposity growth and progress into the obesity-related metabolic disorders. Further studies are needed to predict the obesity as early as possible and preventive system then after.

Blood flow restriction(BFR) exercise is defined as low intensity and short term exercise using pneumatic pressure belts at the top of limbs, which affects the physiological functions of the body. The purpose of this study was to investigate the effects of walking exercise with BFR on inflammatory index, isokinetic muscle function, and thigh circumference in obese women. Eleven obese women(> BMI $25kg/m^2$ & > body fat 30%) wore pneumatic pressure belts on both femurs and performed walking exercise twice per day, 3 days/wk for 4 weeks (walking 2 min; resting 1 min). Data analysis was carried out using paired t-test. Body weight, BMI, and body fat significantly decreased after exercise(p<.05), and right thigh circumference significantly decreased(p<.05). The concentration of plasma IL-6 significantly increased(p<.05) after exercise. TNF-${\alpha}$ level was not statistically different but tended to slightly increase. CRP slightly decreased, although it did not reach statistical significance after exercise. Muscle strength significantly increased in the $60^{\circ}/sec$ of right/left side extension, left side flexion, and $180^{\circ}/sec$ of left side extension after training(p<.05). These results suggest that 4 weeks of blood flow restriction walking exercise has positive effects on inflammatory index and isokinetic muscle function. Therefore, we consider that blood flow restriction exercise can be used for treatment of obesity, related chronic diseases, and metabolic syndrome. Further, blood flow restriction exercise for a short time has similar effects as a high intensity resistance program.

Objectives : The objective of the present study was to investigate alexithymia in major depressive disorder(MDD) and subclinical depression(SCD). Methods : Three hundred eighty-six community-dwelling adults(238 females and 148 males, age 19-79; mean age $43.0{\pm}13.9$) were recruited. Structured clinical Interview for DSM-IV(SCID) was conducted for the diagnosis of MDD or other Axis I psychiatric disorders. The Center for Epidemiological Studies for Depression Scale(CES-D) and the Totonto Alexithymia Scale(TAS) were administered to assess depressive symptom and alexithymia, respectively. Among subjects without MDD, those who had minor depressive disorder on the SCID or high scores(i.e. over 16) on the CES-D were defined as subjects with SCD. TAS total score and factor I, II, III scores of TAS in MDD, SCD, and non-depressive controls were compared. Results : Among 386 subjects, 38 subjects(9.8%) were diagnosed as MDD by DSM-IV criteria, while 57 subjects(14.8%) were classified into SCD group. There were significant differences between 3 groups(MDD, SCD and non-depressive controls) in total score($F_{2,383}=14.0$, p<0.01), factor I(difficulty in identifying feeling)($F_{2,383}=23.4$, p<0.01) and factor II(difficulty in describing feeling)($F_{2,383}=7.8$, p<0.01), but not factor III(external oriented thinking)($F_{2,383}=1.8$, p=0.16) of TAS. In post-hoc analysis, both MDD subjects and SCD subjects had higher scores in TAS total, factor I and factor II, compared to non-depressive controls(all p<0.01). In contrast, there were no significant differences between MDD subjects and SCD subjects in any TAS factor. Conclusion : In this study, both MDD subjects and SCD subjects were more alexithymic than non-depressive control subjects. These findings suggest that SCD, as well as MDD, is also related to alexithymia.
The objective of this study is to examine the effects of servant leadership of security martial arts instructors on the exercise commitment and training satisfaction of trainees. To achieve the objective of this study, the data was collected from 300 trainees of security martial arts gyms located in Seoul, Incheon, and Gyeonggi-do regions by using the convenience sampling method. Total 281 questionnaires were used for the analysis after excluding 19 questionnaires. Using the SPSS 23.0 for data-process, this study conducted the frequency analysis, exploratory factor analysis, reliability analysis, correlation analysis, and multiple regression analysis. First, all the variables showed positive(+) correlations. Second, the presentation of vision of instructors' servant leadership had positive(+) effects on the behavioral commitment while the devoted attitude of instructors' servant leadership had positive(+) effects on the cognitive commitment. Third, the presentation of vision, formation of community, and support for growth of instructors' servant leadership had positive(+) effects on the psychological elements while the presentation of vision and support for growth had positive(+) effects on the environmental elements. The presentation of vision and formation of community had positive(+) effects on the physical elements while the presentation of vision and formation of community had positive(+) effects on the educational elements. The presentation of vision, formation of community, and support for growth had positive(+) effects on the social elements. Fourth, both cognitive commitment and behavioral commitment out of trainees' exercise commitment had positive(+) effects on the psychological elements, environmental elements, physical elements, and educational elements of training satisfaction while only the cognitive commitment had positive(+) effects on the social elements. In summary, the security martial arts instructors should show the leadership like presentation of vision and devotion, and also try hard to satisfy the expectation in many areas to raise the exercise commitment.
The purpose of this study was to provide a basic data for developing and solutions to prevent verbal abuse and to determine the actual overall verbal abuse experience of dental hygienist. Participants were 289 dental hygienists who work in dental hospitals and clinics. The results of this study, 177 dental hygienists experienced verbal abuse. Perpetrators of verbal abuse experience became patient (67.9%), dentist (21.1%). The most common reason for verbal abuse were 'anger about the dental service' (17.0%), 'anger about physical and emotional suffering' (14.1%), 'consider the dental hygienists as subordinate not as colleague or practitioner' (12.6%). The types of verbal abuse were 'taking down' (21.7%), 'yelling' (16.3%), 'being sarcastic' (11.3%). The types of coping with verbal abuse were many aspects of passive coping in order of 'suppress' (12.3%), 'ignore' (8.2%). The result of verbal abuse experience according to working characteristics was significant different to clinical career, main duty, position. The result of self-esteem and job satisfaction according to verbal abuse experience, dental hygienist who had experienced verbal abuse was lower in job satisfaction. Therefore, it should be recognized that experience of verbal abuse in dental hygienist was serious and need to develop prevention programs and research.
Purpose: To investigate the correlation of the serum leptin, adiponectin, and leptin/adiponectin ratio with metabolic disorders in the childhood obesity. Methods: Fifty children (25 obese and 25 non-obese) were recruited in the pediatric outpatient clinic of Chosun University Hospital from January 1st to June 30th 2005. Adiponectin, leptin, anthropometric parameters, glucose, LDL-cholesterol, HDL-cholesterol, total cholesterol, triglyceride, and insulin levels were measured. The correlations of leptin and adiponectin levels with anthropometric parameters, glucose, insulin and lipids were analyzed by Pearson's correlation coefficients. Results: Insulin and leptin levels of the obese group were significantly higher than those of the non-obese group (p<0.05, p<0.001 respectively). HDL-cholesterol and adiponectin levels of the obese group were significantly lower than those of the non-obese group (p<0.005, p<0.05 respectively). In the obese group, leptin level was positively correlated with BMI and the percentage of body fat, but negatively correlated with adiponectin level. Moreover, adiponectin level of the obese group was negatively correlated with BMI and the percentage of body fat, but positively correlated with leptin level. In the non-obese group, only insulin level was positively correlated with adiponectin. In the obese group, leptin/adiponectin ratio was positively correlated with the percentage of body fat and leptin level. Also, leptin/adiponectin ratio was positively correlated with BMI and the percentage of body fat in the non-obese group. Conclusion: Leptin, adiponectin, and leptin/adiponectin ratio did not appear to have a major role linking various metabolic disorders in the childhood obesity, even though they were strongly associated with obesity indices. Also, leptin/adiponectin ratio was associated with obesity indices even in non-obese children.

The human rights of older people have gotten more attention recently in South Korea, a country that is in transition to a super-aged society. This study aimed to systematically review studies on elder abuse and related factors among community-dwelling older adults in South Korea over twenty years (1994-2016). We searched major databases (Riss, DBpia, KISS, KMbase, and PubMed) and identified published studies relevant to the topic. Based on inclusion and exclusion criteria related to study quality, a total of 31 studies were selected for this review. We examined types, measurements, and risk factors of elder abuse as well as study designs in the selected studies, guided by Johannesen's theoretical framework on elder abuse. All of the reviewed studies on elder abuse in Korea were cross-sectional studies, most of which focused on older people living in urban areas, using a non-random sampling method. All of the studies focused on certain types of elder abuse only. Some adopted elder-abuse instruments that were not validated, and others used self-developed instruments without psychometric tests. As for the risk factors of elder abuse in South Korea, the physical and mental health of the victims and aggressors impacted the risk of elder abuse, but general sociodemographic factors such as age, sex, and education were less likely to be related to the risk. In addition, decreasing caregiver burden and building elder-friendly communities are important for the prevention of elder abuse. Needed are further empirical studies on elder abuse with a theoretical framework that gives consideration to the unique sociocultural contexts of Korea. It is also recommended to develop instruments to measure elder abuse reflecting the sociocultural contexts of Korea, and to examine the multi-dimensional risk factors of elder abuse.
