  • One-hundred thirty-six Chinese men and women who are members of the Malaysian Confucian Association from Kuala Lumpur city and suburbs were included in the study. They have been vegetarians for a mean period of about 6 years with the majority of them(91.2%) at lacto/ovo vegetarians. The average age of the male and female subjects in 33 and 34 years respectively. The mean BMI for the men and women are 22.5$\pm$2.4kg/$m^2$ respectively. The mean levels of serum total cholesterol, HDL-chol and LDL-chol for men are 4.27$\pm$0.77, 1,11$\pm$0.26 and 2.60$\pm$0.54mmol/L, while the corresponding values for women are 4.24$\pm$081, 1.34$\pm$0.29 and 2.41$\pm$0.28 mmol/L, All the respondents showed TC/HDL-chol levels within the normal cut-off point of <5.8mmol/L. Majority of the subjects showed normal range levels for serum retinol, carotenoids and $\alpha$-tocopherol. The mean systolic blood pressure for men and women are 122$\pm$16mmHg and 115$\pm$13mmHg, while their diastolic blood pressure are 82$\pm$7mmHg and 79$\pm$7mmHg respectively. Hypertension was found at a higher prevalence in men(17.6%) than among the women(7.1%). None of the respondents smoke cigarettes while approximately two-thirds of them carry out physical exercise at least once a week. their usual dietary intake includes frequent consumption of a wide variety of vegetables, fruits, nuts and legumes. In summary, Malaysian vegetarians have a low cardiovascular risk based on their health-oriented lifestyle.

  • This study was to evaluate water quality characteristics and ecological health using a mulimetric fish model in Taehwa-River watershed during May~September 2009. The ecological health assessments were based on the Index of Biological Integrity (IBI) using fish community and the multimetric model of Qualitative Habitat Evaluation Index (QHEI). For the study, the models of IBI and QHEI were modified as 8 and 11 metric attributes, respectively. We also analyzed spatial patterns of chemical water quality over the period of 2000~2009, using the water chemistry dataset, obtained from the Ministry of Environment, Korea. Values of BOD and COD averaged $1.7\;mg\;L^{-1}$ (scope: $0.1{\sim}31.8\;mg\;L^{-1}$) and $3.6\;mg\;L^{-1}$ (scope: $0.4{\sim}33\;mg\;L^{-1}$), respectively during the study. Total nitrogen (TN) and total phosphorus (TP) averaged $2.8\;mg\;L^{-1}$ and $96.8\;{\mu}g\;L^{-1}$, respectively, indicating an eutrophic-hypertrophic state. Also, TN and TP showed longitudinal increases toward the downriver reach. In the watershed, QHEI values varied from 67.5 (fair condition) to 164.5 (good condition) by the criteria of US EPA (1993). There was a abruptly decreasing tendency from T9 site in the QHEI values. According to 1st and 2nd surveys of Taewha River, multimetric model values of IBI was averaged 26.1 (n=14) with "good" condition (B) and the spatial variation was evident. Our results suggest that the mainstream sites was getting worse health condition along the river gradient due to inputs of the point and non-point sources from the urban (Ulsan city). Overall, dataset of IBI, QHEI, and water chemistry indicated that the ecological river health showed a downriver decline and the pattern was closely associated with habitat degradations and chemical pollutions as the waters pass through the urban region.

  • The forecasting of air pollution is an important and popular topic in environmental engineering. Due to health impacts caused by unacceptable particulate matter (PM) levels, it has become one of the greatest concerns in metropolitan cities like Karaj City in Iran. In this study, the concentration of $PM_{2.5}$ was predicted by applying a multilayer percepteron (MLP) neural network, a radial basis function (RBF) neural network and a Markov chain model. Two months of hourly data including temperature, NO, $NO_2$, $NO_x$, CO, $SO_2$ and $PM_{10}$ were used as inputs to the artificial neural networks. From 1,488 data, 1,300 of data was used to train the models and the rest of the data were applied to test the models. The results of using artificial neural networks indicated that the models performed well in predicting $PM_{2.5}$ concentrations. The application of a Markov chain described the probable occurrences of unhealthy hours. The MLP neural network with two hidden layers including 19 neurons in the first layer and 16 neurons in the second layer provided the best results. The coefficient of determination ($R^2$), Index of Agreement (IA) and Efficiency (E) between the observed and the predicted data using an MLP neural network were 0.92, 0.93 and 0.981, respectively. In the MLP neural network, the MBE was 0.0546 which indicates the adequacy of the model. In the RBF neural network, increasing the number of neurons to 1,488 caused the RMSE to decline from 7.88 to 0.00 and caused $R^2$ to reach 0.93. In the Markov chain model the absolute error was 0.014 which indicated an acceptable accuracy and precision. We concluded the probability of occurrence state duration and transition of $PM_{2.5}$ pollution is predictable using a Markov chain method.

  • This study, targeting the students of "K" university in Busan City area, was performed to draw the groups by food-related lifestyle types and to identify the correlation between each group's attributes of selecting places to eat out and obesity index. The purpose of the study was achieved by means of the PASW Statistic 18.0(Predictive Analytics Software) which conducted frequency analysis, factor analysis, reliability analysis, t-test, ${\chi}^2$-test, non-hierarchical cluster analysis and ANOVA. It turned out that the male university students were 175.59 cm tall and weigh 69.53 kg on average. And the female university students showed their average height of 162.81 cm and weight of 53.42 kg. When examined by the body mass index(BMI), male students were composed of 1.7% of underweight, 64.6% of normal weight, 19.7% of overweight and 14.0% of obese. As for the female students, 22.9% were classified as underweight, 62.7% as normal weight, 8.5% as overweight and 5.9% as obese. The food-related lifestyle categories were divided into five factors; health seeking type, safety seeking type, mood seeking type, taste seeking type, and western food seeking type. The four attributes of selecting places to eat out included quality of food and service, price reasonableness, accessibility and atmosphere, and experience to have eaten. With regard to food-related lifestyle, the groups were named by cluster 1 [careless diet group], Cluster 2 [health oriented group], and cluster3 [careless healthcare group]. In terms of the correlation between the clusters by food-related lifestyle and their attributes of selecting places to eat out, Cluster 1 had a high mean value in experience to have eaten, Cluster 2 quality of food and service, Cluster 3 accessibility and atmosphere.

  • The purpose of this survey was to assess the nutritional status of preschool children a county of Jeju Island. This study used health examinations results for preschool aged children, performed by the public health center of Pukjeju-gun in Jeju-do for over three years from 1999 to 2001, of children in kindergartens and children homes. The target children totaled 5,990 from the ages three to six. For a control group, 316 children from the nearby Jeju-city areas were included as well. The items of this research included height, weight, and hemoglobin values. 1. The average height of boys from ages three to six were 96.35cm, 102.14cm, 109.94cm, 111.00cm respectively, and girls were 94.96cm, 100.93cm, 108.33cm, 110.54cm respectively. The average weights of boys from ages three to six were 15.42kg, 16.93kg, 19.65kg, 19.67kg respectively, and the weight of girls were 14.90kg, 16.45kg, 18.88kg, 19.50kg respectively. 2. The percentages of children who did not reach 90% of the Korean standard height were 4.3% in boys 4.1% in girls. The percentages of children with less than 80% of the Korean standard weight were 7.6% in boys and 6.8% girls. The percentages of children over 120% of Korean standard weight were 10.4% in boys and 11.4% in girls. 3. As for the obesity level, the percentage of boys under-weighed(under 10% for standard weight for height) were 11.6% and girls, 9.5%, and the percentages of boys and girls with obesity($\geq$20%) were 3.6% and 4.4% respectively. 4. The mean hemoglobin value of boys were 11.83g/$d\ell$ and girls, 11.83g/$d\ell$. These were lower than the value of average normal Korean children (12.5g/$d\ell$). The mena hemoglobin values of the children in Pukjeju-gun were considerably lower than that of the children living in Jeju-city(12.3g/$d\ell$) as well. Anemia of Children of Pukjeju-gun were estimated at 38.1%(male) and 37.2%(female), by using Hemoglobin level(<11.5g/$d\ell$ 5. The rates of children included within the normal range of obesity level in Jeju-city and Pukjeju- gun were boys 80.2%, 71.6% in boys, and 77.4%, 72.4% in girls. The percentage of children living in PukJeju-gun included within the normal range were considerably low. 6. There were no changes in the Body Mass Index (BMI) during the three years from 1999 to 2001, but the percentage of children with anemia significantly increased. Health care for preschool aged children, especially in the rural areas, is very important. Centering on public health centers, it is necessary to systematically promote health care in the rural areas.

  • This purpose of study was to identify variables predicting basic psychological need in hemodialysis patients. The participants were 134 patients from two major general hospitals and two dialysis center located in J city. Data were collected using self-report questionnaires and physiological index. Data analysis was done by using SPSS WIN 18.0 program for one-way ANOVA, independent t-test, Pearson correlation coefficients, and multiple regression. This study showed a negative correlation between basic psychological need and uncertainty(r=--.464, p<.001), depression(r=-.422, p<.001). In addition, relationships and physiological index were Positively correlated. The uncertainty(${\beta}=-.345$), depression(${\beta}=-.279$), physiological index(${\beta}=-.117$) have a 29% explanatory power for the basic psychological need in hemodialysis patients. Physiological index, uncertainty and depression in turn influenced the basic psychological needs of hemodialysis patients. It is necessary to develop nursing strategies and programs to reduce disease uncertainty and depression in order to increase self-deterministic health behavior through autonomy, competence and relationship satisfaction.

  • Purpose: This thesis focuses on researching the burden of the Home Health Care that the Family Care-givers have. Method: This study had been conducted for the duration of 3 consecutive months from January 2006 to March 2006 and had investigated 120 person registered as the Home Health Care Clients to a University Hospital located in Incheon City. The thesis adopted the 'feeling of burden' measuring method jointly developed by Seo, Mi-Hye and Oh, Ga-Sil(1993), and FACES-III(Family Adaptability Cohesion Evaluation) developed by Olson(1985) etc. translated by Kim, Yun-Hee(1989) as the measuring method for Family Function. Result: The overall Health Status of the Home Health Care Clients was 2.18 point of average out of 3 point, where as 1.83 for Activities of Daily living and 1.98 for Vital sign, which are below the average. In the mean time, the Competence for Modified Barthel Index marked 30.88 point out of the full mark. The analyzed result of the burden that the family members have was 3.43 point of average out of 5 point which shows that the interviewee feel that they are considerable burden to their families. When it comes to 'the Burden to the family members' and 'the Function of the family' according to the characteristics of the patient, the result shows statistically significant differences, which are varied according to gender, the relationship between the care-givers and the patients. When it comes to the Family Cohesion, the difference was examined as 'statistically significant' according to the Academic background of the patients and the relationship between the patients and the interviewee.(p<0.05). The result also suggests that there exists 'Negative correlation' among the level of patients' health status, the Family Cohesion and the Family Burden. Conclusion: From the result of this study stated above, this thesis is strongly insisting that there is an urgent need for us to develop a health care mediation program, which could eventually reduce the burden of home health care that the patients' family have. At the same time, a follow-up research to prove the effect of the program is imminent.
