This study was designed to find out the effects of aerobic exercise on the serum lipids in the middle-aged women. The effects of aerobic dancing on serum total cholesterol(TC), triglyceride(TG) and HDL-cholesterol (HDL-C) were studied in eight sedentary women(control group) and twenty seven aerobic exercising women(aerobic group) , aged 35∼45%. Aerobic exercising subjects were divided into 3 group; 2 to 3 months exercising group(Al), 4 to 10 months exercising group(AH), over 1 year exercising group(AIII) according to the periods of exercise. The serum lipid levels of aerobic exercising groups(AI, AII, AIIII) were compared with those of control group. The results statistically analyzed were summarized as follows : 1) The serum TG levels of aerobic groups decreased very significantly compared with those of control group(p< 0.001) and tended to be lower with the increase in aerobic periods. But there were no significant differences among aerobic groups by ANOVA. 2) The serum TC levels of aerobic groups decreased compared with those of control group and tended to be lower with the increase of aerobic periods. But there were no significant differences among groups. 3) Serum HDL-cholestrol level of A I group was elevated significantly compared with that of control group and significant difference was observed according to the aerobic periods : AR group exhibited higher serum HDL-cholesterol values than AH group, and AH group higher than A I group.

This study was conducted to investigate effects of nutrition education and exercise intervention on health and diet quality of middle-aged women. The subjects were 209 women who wanted to involve in the health promotion program run by Jincheon-Gun Health Center. Nutrition education was given once a week and dance sports were done twice a week for 3 months. Nutrient intakes were assessed by 24-hour recall method and food records. Dietary habits and nutrition knowledge were investigated by self-administered questionnaires before and after the intervention program. Body and blood compositions were measured before and after the program. The nutrient adequacy ratio (NAR) was significantly increased in energy, protein, vitamin A, vitamin B2 and calcium, mean adequacy ration (MAR) was significantly increased (p < 0.05), and also the index of nutritional quality (INQ) was significantly increased in protein (p < 0.01). Percent (%) RIs of protein (p < 0.01) and calcium (p < 0.05) were significantly increased and body weight (p < 0.001), body fat (p < 0.01), soft lean mass (p < 0.01) and BMI (p < 0.001) decreased. Over the 3-month study, there was a significant trend toward higher HDL-C and albumin levels and lower LDL-C level (p < 0.001). The results showed that nutrition education and exercise intervention could improve the body health and the diet quality.

The purpose of this study was to compare nutrient intakes and blood lipids of middle-aged women according to the obesity index by %Fat. Subjects were assigned to one of the following groups based on percentage of body fat (%Fat): normal weight (18% ~ < 28%), overweight (28% ~ < 33%) and obesity (over 33%). Nutrient intakes were evaluated based on questionnaires of 24 hours recall method and blood lipids were analyzed by blood analyzer. The results were as follows. 1) Nutrient intakes were that carbohydrates and fat intakes in obesity group were higher than normal and overweight group but the difference was not significant, and protein intake rate was similar all groups. The intake rate of calcium was higher in normal group than obesity group (p < 0.05), and obesity group ingested under dietary reference intakes. The intake rate of iron was higher in obesity group than normal group (p < 0.05). 2) TG, TC, VLDL and TC/HDL in obesity group were higher than normal group (p < 0.001). The attack rate of coronary heart disease in obesity group is higher than normal group (p < 0.01), LDL, blood glucose and blood pressure in obesity group were higher than normal group (p < 0.01), and HDL was a little higher in normal group than obesity group, but the difference was not significant. 3) The correlation of anthropometric measurements, blood glucose, blood lipid, and blood pressure had significant results. Weight was associated positive level with blood glucose, blood lipid and blood pressure. Waist and WHR were associated positive level with blood glucose and blood lipid but weren't associated with blood pressure. BMI was associated positive level with blood glucose, blood lipid and blood pressure, %Fat was associated positive level with blood lipid and blood pressure, but wasn't associated with blood glucose. These results suggest that the decrease of waist on blood glucose control is better than decrease of % Fat and BMI, the decrease of %Fat and BMI on blood pressure control is better than decrease of waist, and the decrease of %Fat on blood lipid control is better than waist and BMI. The nutritional education for obesity treatment must perform to analyze the blood and assess the obesity degree by %Fat, waist and BMI before nutritional education, so the obesity treatment will be effectively.

Purpose: The purpose of this study was to examine a combined influence of obesity and metabolic syndrome on ischemic heart disease in Korean middle aged and older adults. Methods: This study used secondary data from the 2013 Korea National Health and Nutrition Examination Survey. A total of 3,726 adults over age 40 were included. Logistic regression was used for analysis of complex samples. Gender, age, educational level, family income, family history of ischemic heart disease, physical activity, smoking, and heavy alcohol consumption were analyzed as covariates. Results: Ischemic heart disease was more prevalent among adults with metabolic syndrome regardless of obesity (non-obesity: Adjusted Odds Ratio [AOR]: 3.044, 95% Confidence Interval [CI]: 1.163-7.967, overweight: AOR: 2.805, 95% CI: 1.246-6.316, obese: AOR: 3.137, 95% CI: 1.548-6.358) compared to the reference group, defined as adults with non-obesity and non-metabolic syndrome. Odds of ischemic heart disease were not significant in the group with obesity and non-metabolic syndrome compared to the reference group. Conclusion: The results of this study show that the population with metabolic syndrome is an at-risk group for ischemic heart disease. Thus, management of metabolic syndrome is required for prevention of ischemic heart disease.

In the case study of this paper, sensitivity experiments are carried out using the mesoscale non-hydrostatic Weather Research and Forecasting (WRF) model to investigate the impact of tropical cyclone (TC) Soudelor (2003) on the East Asian subtropical upper-level jet (EASJ) before TC Soudelor transformed into an extratropical cyclone. The physical mechanism for changes in the EASJ intensity and position caused by TC Soudelor is explored. Results indicate that TC Soudelor would warm the air in the middle and upper troposphere over the Japan Sea and the adjacent areas through stimulating northward propagating teleconnection pattern as well as releasing large amounts of latent heat, which led to increase (decrease) the meridional air temperature gradient to the south (north) below the EASJ axis. As a result, the geopotential height abnormally increased in the upper troposphere, resulting in an anomalous anticyclonic circulation belt along the EASJ axis. Correspondingly, the westerly winds to the north (south) of the EASJ axis intensified (weakened) and the EASJ axis shifted northward by one degree. The case study also suggests that before the extratropical cyclone transition of TC Soudelor, the TC activities had exerted significant impacts on the EASJ through thermodynamic processes.

The ozone concentration is one of the important environmental issue for measurement of the atmospheric condition of the country. This study focuses on applying the Autoregressive Error (ARE) model for analyzing the ozone data at middle part of the Gyeonggi-Do, Anyang monitoring site in Korea. In the ARE model, eight meteorological variables and four pollution variables are used as the explanatory variables. The eight meteorological variables are daily maximum temperature, wind speed, amount of cloud, global radiation, relative humidity, rainfall, dew point temperature, and water vapor pressure. The four air pollution variables are sulfur dioxide $(SO_2)$, nitrogen dioxide $(NO_2)$, carbon monoxide (CO), and particulate matter 10 (PM10). The result shows that ARE models both overall and monthly data are suited for describing the oBone concentration. In the ARE model for overall ozone data, ozone concentration can be explained about 71% to by the PM10, global radiation and wind speed. Also the four types of ARE models for high level of ozone data (over 80 ppb) have been analyzed. In the best ARE model for high level of ozone data, ozone can be explained about 96% by the PM10, daliy maximum temperature, and cloud amount.

On 31 July 2014, there was a localized torrential rainfall ($58.5mm\;hr^{-1}$) caused by a strong convective cell with thunder showers over Daegwallyeong. In the surface synoptic chart, a typhoon was positioned in the East China Sea and the subtropical high was expanded to the Korean peninsula. A WRF (Weather Research and Forecasting) numerical simulation with a resolution of 1 km was performed for a detailed analysis. The simulation result showed a similar pattern in a reflectivity distribution particularly over the Gangwon-do region, compared with the radar reflectivity. According to the results of the WRF simulation, the process and mechanism of the localized heavy rainfall over Daegwallyeong are as follows: (1) a convective instability over the middle part of the Korean peninsula was enhanced due to the low level advection of warm and humid air from the North Pacific high. (2) There was easterly flow from the coast to the mountainous regions around Daegwallyeong, which was generated by the differential heating of the insolation among Daegwallyeong and the Yeongdong coastal plain, and nearby coastal waters. (3) In addition, westerly flow from the western part of Daegwallyeong caused a strong convergence in this region, generating a strong upward motion combined by an orographic effect. (4) This brought about a new convective cell over Daegwallyeong. And this cell was more developed by the outflow from another thunderstorm cell to the south, and finally these two cells were merged to develop as a strong convective cell with thunder showers, leading to the record breaking maximum rainfall per hour ($58.5mm\;hr^{-1}$) in July.

Through a questionnaire survey of 607 respondents over 20 years old currently residing in Seoul, general conditions, items and amount of daily diet, preference of dining-out and instant food, and concern for health were surveyed and the results are as follows. A large portion of respondents, at 36.2% of all respondents, were 20 years old, 57.7% of them graduated from high school or over, and most of them(61.9%) were over middle-class level of living standard. More than half (50.9%) of whom paid less than 10% for dining-out took breakfast as a rule, and 38.3% of whom regularly took meals and 37.3% of them took their regular daily routines. But among whom spent more than 31% for dining-out 46.2% of them took snacks between meals every day. Also, among whom spent more then 31% for dining-out, about 25.6% of them usually dined out every day. On concerns for health, among whom spent less than 10% of dining-out expense, 53.9% of them took exercise almost every day and 32.8% for 30 minutes, and 34.6% of them were generally healthy and 67.5% of them had normal blood pressure. But among whom spent more than 31% for dining-out expenses, 10.3% of them were not healthy, 15.4% had higher blood pressure and 20.5% had lower blood pressure, thus those portion were relatively higher compared with the former group. From those research results, therefore, group who spent lower dining-out expenses were older people with lower educational and living level but regularly took breakfast and exercise. Thus, their daily schedules were routine and took regular meals with healthy condition. The group with lower dining-out expense took right food pattern and kept healthy condition, and, therefore, it implied that dining-out gave significant influence to food pattern of grown-ups. Therefore, nutrition education for grown-ups might be necessary again and our foods as a diet should be re-evaluated and re-highlighted. To formulate the practical nutrition education in early childhood, practical, systematic, and continuous nutrition education might be required and effective and multidimensional education programs should be developed. In addition, various menus of breakfast with diverse materials, wide range of nutrition, and being convenient and time-saving must be studied in the near future.
