  • Introduction. Despite the fact that half of premature deaths are caused by unhealthy lifestyles such as smoking tobacco, sedentary lifestyle, alcohol and drug abuse and poor nutrition, there are no theoretical models which accurately explain these health promotion related behaviors. This study tests a new model of health behavior called the Model of Health Promotion Behavior. This model draws on elements and frameworks suggested by the Health Belief Model, Social Cognitive Theory, the Theory of Planned Action and the Health Promotion Model. This model is intended as a general model of behavior but this first test of the model uses amount of exercise as the outcome behavior. Design. This study utilized a cross sectional mail-out, mail-back survey design to determine the elements within the model that best explained intentions to exercise and those that best explained amount of exercise. A follow-up questionnaire was mailed to all respondents to the first questionnaire about 10 months after the initial survey. A pretest was conducted to refine the questionnaire and a pilot study to test the protocols and assumptions used to calculate the required sample size. Sample. The sample was drawn from 2000 eligible participants at two blue collar (utility company and part of a hospital) and two white collar (bank and pharmaceutical) companies located in Southeastern Michigan. Both white collar site had employee fitness centers and all four sites offered health promotion programs. In the first survey, 982 responses were received (49.1%) after two mailings to non-respondents and one additional mailing to secure answers to missing data, with 845 usable cases for the analyzing current intentions and 918 usable cases for the explaining of amount of current exercise analysis. In the follow-up survey, questionnaires were mailed to the 982 employees who responded to the initial survey. After one follow-up mailing to non-respondents, and one mailing to secure answers to missing data, 697 (71.0%) responses were received, with 627 (63.8%) usable cases to predict intentions and 673 (68.5%) usable cases to predict amount of exercise. Measures. The questionnaire in the initial survey had 15 scales and 134 items; these scales measured each of the variables in the model. Thirteen of the scales were drawn from the literature, all had Cronbach's alpha scores above .74 and all but three had scores above .80. The questionnaire in the second mailing had only 10 items, and measured only outcome variables. Analysis. The analysis included calculation of scale scores, Cronbach's alpha, zero order correlations, and factor analysis, ordinary least square analysis, hierarchical tests of interaction terms and path analysis, and comparisons of results based on a random split of the data and splits based on gender and employer site. The power of the regression analysis was .99 at the .01 significance level for the model as a whole. Results. Self efficacy and Non-Health Benefits emerged as the most powerful predictors of Intentions to exercise, together explaining approximately 19% of the variance in future Intentions. Intentions, and the interaction of Intentions with Barriers, with Support of Friends, and with Self Efficacy were the most consistent predictors of amount of future exercise, together explaining 38% of the variance. With the inclusion of Prior Exercise History the model explained 52% of the variance in amount of exercise 10 months later. There were very few differences in the variables that emerged as important predictors of intentions or exercise in the different employer sites or between males and females. Discussion. This new model is viable in predicting intentions to exercise and amount of exercise, both in absolute terms and when compared to existing models.

  • To evaluate the possibility of hardening of rice seedlings to chilling injury by low temperature conditioning for improvement of nursery temperature management a chilling sensitive new variety Tongil from Indica \times Japonica cross and a chilling tolerant Japonica variety Jinheung were reared by the 3rd leaf-stage in a day $30^{\circ}C/night\; 20^{\circ}C$ growth chamber, and were subjected to temperature conditioning for hardening against chilling injury for 6 days. Then the seedlings conditioned and unconditioned were chilled in a day and night $8^{\circ}C$ chamber for 2, 4, 6, or 8 days long and returned to the day and night $30^{\circ}C/night\; 20^{\circ}C$ condition for development of chilling injuries. Survival rate after chilling injury development of the variety Tongil showed distinct effect of hardening, i. e. the unhardened-25 % survival, the hardened by a gradual drop of temperature regime $(30^{\circ}C/20^{\circ}C\rightarrow24^{\circ}C/14^{\circ}C\rightarrow18^{\circ}C/12^{\circ}C\rightarrow8^{\circ}C)4 -59% survival and the hardened. by repeated brief exposure (4hrs. to 6hrs.) to $8^{\circ}C$ shock-89% survival against chilling of $8^{\circ}C$ for 4 days long. The variety Jinheung survived even against 8 days chilling at $8^{\circ}C$ C, but the discoloration rate of leaves due to chilling showed noticeably the hardening effect as repeated shock was much better than the gradually lowering temperatures.

  • Purpose: This study investigates the relationship between sleep duration, sleep quality, time use, and dietary quality of adolescents. Methods: A cross-sectional study was conducted, enrolling 423 high school students (112 male and 311 female students) in Chungnam using a questionnaire comprising general characteristics, sleep status, use of time, and Nutrition Quotient for Korean Adolescents (NQ-A). Results: On weekdays, male students reported getting 6.6 hours of sleep, which was significantly higher than the 5.8 hours reported by female students. The sleep quality score between male and female students was not significantly different on weekdays and weekends. Comparing the students categorized as getting 6 hours of sleep duration on weekdays and 8 hours on weekends, a significantly higher total NQ-A score was obtained for the long sleep duration group of female students on weekdays. In male students who reported increased screen time on weekdays and study time on weekends, there was a greater frequency of short sleep duration. Our data also revealed that the longer the sleep duration higher the NQ-A score. In addition, higher NQ-A scores were determined with shorter screen time and more prolonged exercise time. Conclusion: Our results suggest that intense study time and excessive use of smartphones have a negative effect on sleep in high school students. In addition, poor sleep quality and lack of sleep are likely to affect eating habits and nutritional status. Therefore, there is a need to provide nutritional education to adolescents imparting knowledge that associates desirable sleep habits and the correct use of time.

  • Certain pre-transfusion tests are not commonly performed during emergency blood transfusion. In this study, we reviewed and analyzed the data of post-blood transfusion antibody screening tests to establish the effects of unexpected antibodies causing hemolytic transfusion reactions. We reviewed information published domestically and internationally, and selected the data of 68,602 antibody screening tests and 528 antibody identification tests conducted at P hospital. We found that unexpected antibody positive (1198,1.74%), Rh type (161, 30.49%), Lewis type (67, 12.69%), others (Di (a), 28, 5.30%). The anti-E type positive was 93 (17.61%), and that of the cases with anti-C (13, 2.46%). Only data of domestic cases were included for analysis that were published before 2007, which established the presence of antibodies of the following types and numbers of cases: anti-E (196, 22.45%), anti-Le a (82, 9.39%), and anti-E+C (60, 6.87%). In 2018, anti-E (107, 17.12%), anti-E+Canti-E+C (56, 8.96%), and anti-Di a (28, 4.48%) were detected. In other domestic cases, S hospital was detect to anti-E, anti-Le a, anti-E+C. The Anti-E, anti-D, anti-E+C, and anti-C+E were detected in D hospital. In Saudi Arabia, Anti-D, anti-E, and anti-Jka was detected. The Anti-M, Anti-N, Anti-Le (a), and Anti-D were detected in India. Requests for emergency blood transfusion increased 1.8 times after the opening of the trauma center. This study has the disadvantage of being a cross-sectional study. additional studies are needed to provide basic information on alternative treatments that can increase the safety and reduce the side effects of hemolytic transfusion in emergency transfusion situations.

  • The purpose of this study was to identify work-family balance values(work-family centrality, marriage value, child-care value, work value etc) in Korea, Japan and U. K.. Moreover, This article investigated the attitudinal generational gap in each countries. Participants were 311 Korean, 324 Japanese and 322 English married working women, who were in the thirties fifties. The major findings of this study were as follows. Compared to Japan and U. K., Korean married working women were more work-centered and likely to seek for extrinsic work value as well as intrinsic work value. While they were highly thought that a woman should work despite of her marriage, it was also strongly concerned if their work negatively affected family life, they should be better to quit their job. These results showed that conservative-liberal values were coexisted in Korean participants. Secondly, U. K. participants were more centered on the family-oriented value and thought that women were not necessary to work in work-family conflict, in comparison to Korean and Japanese. As a result of cluster analysis, they were a lot distributed in 'woman's family care oriented group' which was weigh on woman's role as a family care giver as well as 'family value oriented group'. Thirdly, Japan participants not only were less family-centered but also less work-centered. In the similar vein, they were less motivated and oriented to all of intrinsic and extrinsic work values compared with participants in Koran and U. K. On the other hand, Japanese participants, in sharp contrast to Korean, had a liberal viewpoint in work-family related values, such as woman's work, career break caused by work-family conflict, and family values. We were trying to interpret these results in consideration of socio-economic-politic as well as psychological aspects.

  • The objective of the study was to examine the associations of dietary carbohydrate and fat intake with the prevalence of metabolic syndrome in Korean women. A cross-sectional study was employed based on data from the Korea National Health and Nutrition Examination (2007-2016). A total of 22,850 women aged 19 to 69 years were studied after excluding responses from pregnant or lactating women and those with missing metabolic values. Dietary intake data were collected with a 24-hour recall method. Dietary carbohydrate and fat intakes were divided into quintiles. After controlling for confounding variables, a multivariable logistic regression and general linear model were used. The findings indicated that HDL cholesterol levels were lower (p for trend<0.01), while triglyceride levels (p for trend=0.04), waist circumference (p for trend<0.01), and systolic blood pressure (p for trend<0.01) were higher among participants in the highest quintile of carbohydrate intake compared to those in the lowest quintile. Participants in the highest quintile of fat intake had lower waist circumference (p for trend=0.02), triglyceride level (p for trend<0.01), and systolic blood pressure (p for trend<0.01), while higher HDL cholesterol level (p for trend<0.01) compared to those in the lowest fat intake quintile. Metabolic syndrome was more likely to be present in the highest quintile of carbohydrates intake than in the lowest quintile (5th quintile vs. 1st quintile, OR: 1.32; 95% CI: 1.11 to 1.57). However, metabolic syndrome was less likely to be present in the highest quintile of fat intake than in the lowest quintile (5th quintile vs. 1st quintile, OR: 0.73; 95% CI: 0.61 to 0.86). This study revealed that high dietary carbohydrate intake and low dietary fat intake were associated with metabolic syndrome in Korean women.

  • The purpose of this study was to predict abdominal obesity with 3-Dimensional computed tomography (3D CT) measurements of kidneys by analyzing the correlation between kidney sizes and abdominal obesity level. The subjects were 178 healthy adults without underlying diseases who had a comprehensive health examination at the Health Medical Center of Jesus Hospital in Jeonju. Abdominal obesity was measured by CT cross-sectional image at the level of the umbilicus and divided into visceral fat area, subcutaneous fat area, visceral fat/total fat ratio. The average comparison of kidney sizes classified according to abdominal obesity were performed through one-way analysis of variance (ANOVA) and Scheffe test. Pearson correlation analysis was performed to correlate all measurement values. The results of kidney size ANOVA analysis according to abdominal obesity were as follows. The means of kidney measurements according to visceral fat classification were significantly different in all kidney measurements (p<0.05). And in case of subcutaneous fat classification, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in the right kidney width (p<0.05). In case of visceral fat area/total fat area ratio, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in both kidneys width (p<0.05). Pearson correlation between kidneys measurements and CT abdominal obesity showed that visceral fat area had the highest correlation with the left kidney width measured by 3D CT (r=0.467) and subcutaneous fat area had correlation with the right kidney width measured by 3D CT (r=0.249). The visceral fat area/total fat area ratio had correlation with the left kidney width measured by 3D CT (r=0.291).

  • Objectives : This study was aimed to evaluate the current status of East-West integrated treatment in stroke and brain disease and to discuss further plans. Methods : The medical records of patients who visited the stroke and brain disease center at Kyung Hee University, East-West Neo Medical Center from May 2006 to August 2010 were evaluated. The general characteristics of patients who underwent integrated treatment, trend in the number of cross referrals were initially evaluated. Later major disorders, the reasons of referrals and the number of visits in outpatients were analyzed. Results : 1. 3496 patients were referred from the eastern medical hospital to the western medical hospital and 2440 patients from the western medical hospital to the eastern medical hospital. The number of patients reached a peak alter the opening of the hospital and has decreased from then on. Referrals of female patients were more than those of male patients and patients over 50 years old were the most. 2. Admitted patients with stroke of chronic stage were most commonly referred from the eastern medical hospital to the western medical hospital and cerebral infarction was most common from the western medical hospital to the eastern medical hospital. Among the outpatients cerebral infarction topped from east to west, and stroke of chronic stage from west to east. 3. 36.6% of the patients from east to west received integrated treatment more than 3 times and 28.6% from west to east. Headache was the second most common reason to be referred from west to east and 36.7% of patients didn't continue to have either of the treatment and 30.3% received eastern treatment only, Conclusions: According to this study, chronic stroke management was successfully performed in the outpatient clinic in the form of East-West integration treatment. Further research on other diseases such as headache is recommended.

  • This study examines the process of Chou Sun-Ae's spiritual formation in the light of Carl Jung's conception of individuation. Spirituality is defined in different ways by different scholars, but most consider self-transcendence as a necessary element. This self-transcendence can occur in the relationship with self, with others, and with the transcendent. In the relationship with the self, it appears as self-objectification; with others, it is as moving toward others; and in the relationship with the transcendent, it moves toward the transcendent. Spirituality is closely related to individual identity, in that it surrounds and integrates life. Spiritual formation is thus closely related to Jung's concept of individuation, as this involves the separation of persona and ego, and shadow recognition which are closely related to the level of self-objectification. In addition, the withdrawal of shadow projection that occurs in individuation is closely related to moving toward others, in that it recognizes the shadow instead of blaming others, allowing one to look at others without prejudice. The fact that Jesus Christ is the symbol of the Self, the driving force of the individuation process, tells us that spirituality leading to a relationship with the transcendent God and Jung's theory are closely related to each other. Thus, if we examine the process of spiritual formation through the Jung's individuation process, we can better understand the psychodynamic dimension of spirituality. This article investigates the process of Chou Sun-Ae's spiritual formation through Jung's individuation process. Throughout her 98 years, Chou Sun-Ae experienced national pain and hardships, as well as personal adversity and difficulties; but through all of these hardships, conflicts, and difficult moments, she accomplished individualization. Therefore, by examining the spiritual formation through individuation in Chou Sun-Ae, I consider the direction of Christian spiritual education. In this study, three main characteristics of Chou Sun-Ae's spiritual formation can be identified. First, through a life of repentance, the identification between persona and ego can be weakened. Second, the ego develops, and individualization is achieved, through a new calling. Third, in shadow integration, the spiritual development comes to recognize Jesus Christ on the cross and achieve the process of sanctification. Investigating the direction of Christian spiritual education through Chou Sun-Ae's spiritual formation indicates that Christian spiritual education should harmonize vertical and horizontal relations and should develop an experience of the transcendent God in everyday life. By this means, the believer can achieve Self-realization and be a true Christian who practices love for God and love for neighbors.

  • Previous studies on the numerical simulation at the tidal reach of Han River tend to restrict downstream boundary as Jeon-ryu station due to difficulties in gaining cross section data and tidal elevation values at Yu-do. But, in this study, geometries beyond the confluence of Gok-reung stream and Im-jin River are constructed based on the numerical sea map; tidal elevation at the downstream boundary, Yu-do is estimated by harmonic analysis of In-cheon tide gage station so that hydrodynamic and diffusion behavior have been analyzed. The domain ranging from Shin-gok submerged weir to Yu-do is selected (which is 36.8 km in length). RMA-2 and RAM4 developed by Il Won Seo (2008) are applied to simulate flow and diffusion behavior, respectively. Numerical results of flow characteristic are compared with the measured data at Jeon-ryu station. Simulation is carried out from June 23 to 25 in 2006 on the ground that hydrologic data is satisfactory and tidal difference is huge during that period. The result shows that reverse flow occurs 5 times according to the tidal elevation at Yu-do and the maximum reverse flow is observed up to Jang-hang IC, which is 32.9 km in length. Also analysis is focused on the process of generation and disappearance of reverse flow, the distribution of water surface elevation and velocity along the maximum velocity line, and the transport of nonconservative pollutant. Pollutant injected from Gul-po stream spreads widely across the river; however, the size of BOD cloud entering from Gok-reung stream is relatively small because water depth at the mid and left side becomes deeper and maximum velocity occurs along the right bank so that transverse mixing is completed quickly. Finally, mixing characteristic of horizontal salinity distribution is obtained by estimating the salinity input with analytical solution of 1D advection-dispersion equation.
