The purpose of this work was to study the relationships between dietary intake and serum lipid profile in 293 adult subjects (mean age: $45.9{\pm}0.7$, men: 163, women: 130) who visited health promotion center. The anthropometric and biochemical blood indices were measured, and nutritional intakes were assessed using a food frequency questionnaire method. The subjects were divided by three groups in accordance with a standard for treating hyperlipidemia; those who had blood cholesterol levels above 240 mL/dL or triglyceride levels above 200 mL/dL were put into the risk group (Risk), while those with blood cholesterol levels below 200 mL/dL and triglyceride levels below 150 mL/dL were put into the control group (Control). Subjects who were between the two groups in terms of blood cholesterol and triglyceride levels were put into the borderline group (Borderline). Risk group showed significantly higher body mass index, body weight, waist circumference, and fat content compared to control group. The levels of calorie, carbohydrate, fat, and protein intake were significantly higher in the risk group than control group. There were significantly positive correlations between dietary calorie, carbohydrate, fat, and protein intake and blood triglyceride concentration. The blood HDL-cholesterol concentration had negative correlation with carbohydrate intake. These results suggested that overeating may be one of important factors affecting hyperlipidemia in Korean adults.

Background: We prospectively investigated types, incidences, and risk factors for arrhythmias after open heart surgery in adults. Materials and methods: From June 1994 to May 1995, we performed 302 cases of adult cardiac surgery at our department. This study group consisted of 150 men and 152 women, with a mean age of 43.9±28.0(range 16 to 75)years. We included all the patients irrespective of their operative types or disease entities. Results: The overall incidence of arrhythmias after open heart surgery in adults was 58.3%. The incidence of postoperative arrhythmias for redo-valvular heart surgery was 77.8%, and those for simple valvular procedure, coronary artery bypass surgery, aortic surgery, and congenital heart disease were 70.8%, 45.3%, 40.0%, and 29.5%, respectively. Eight out of twelve risk factors showed statistical significance for the development of postoperative arrhythmias. They were preoperative history of arrhythmias, antiarrhythmic drug medication, previous cardiac surgery, larger left ventricular end-diastolic, end-systolic dimension, left atrial dimension on preoperative echocardiogram, longer cardiopulmonary bypass time and aortic cross clamping time. Univariated analyses for age and types of cardioplegic solution did not show statistical significance. Conclusions: Prospective study on postoperative arrhythmias occurrence, treatment and prevention of is warrauted to draw more clear conclusion.

Objectives : The object of this study was to evaluate repeatability of portable spirometry and to determine an appropriate equation for predicted value. Materials and Methods : The subjects were 76 men and 45 women recruited from among Kyunghee University oriental medical students. Portable spirometry was performed via the procedure recommended in ATS guidelines. Repeatability of spirometry was checked against ATS repeatability standards and NHLEP QC grade. Percentage of predicted value of non-smokers was calculated through a Caucasian population-based regression equation(by Morris et al.) and Korean population based regression equation(by Kim et al.). These were compared. Result : 91.7% of subjects matched repeatability standards of ATS and 95% of subjects got interpretable NHLEP QC grades of A, B, and C. Mean percentage of predicted value by Morris et al. were as follows: Mean of FVC% was 90.86, FEV1% was 96.66, FEV1/FVC% was 107.48. Mean percentage of predicted value by Kim et al. were as follows. Mean FVC% was 92.38, FEV1% was 89.77, FEV1/FVC% was 96.95. Conclusions : Results of this study show that more than 90% of subjects meet repeatability criteria. This supports a role for the portable spirometer as a primary oriental medical office tool. Further, results are a verify that they Korean population-based predicted value equation is a more appropriate standard than the Caucasian population-based one, but a still more accurate standard is needed for the Korean adult population.

The authors attempted to investigate the oxygen consumption rate of sexuals in the water-striders, Gerris paludum insuralis, at four temperature groups of 25, 30, 35 and $40^\\circ C$ in a series of studies on respiration of a heminetabolous insects. THe results are summarised as follows: (1) At $30^\\circ C$, the change of oxygen consumption rate according to the lapse of time was small in comparison with the other three temperature groups which shows a cyclic decreasing pattern. The rate during initial and final 5 minutes was much alike. Thereupon, the optimum temperature was regarded as $30^\\circ C$. (2) The oxygen consumption rate of male was higher than that of female. (3) The oxygen consumption rates at 25, 30, 35 and $40^\\circ C$ were 0.42, 0.49, 0.79 and 1.11 $\\mu$l/mg/h respectively. That is, the rate was increased as the temperature was increased. (4) The $Q_10$ of male showed a high value in the lower temperature interval ($25^\\circ C \\sim 35^\\circ C$), but the female showed a high value in the higher temperature interval ($30^\\circ C \\sim 40^\\circ C$). The mean $Q_10$ was 2.12. (5) The respiratory rate was decreased as the body weight was increased in the above fresh weight of 10mg and dry weight 5 mg. (6) The upper temperature threshold for respiration was $48.31^\\circ C$ and the lower temperature threshold was $17.68^\\circ C$. (7) The ceasing time of breathing at the other three temperature groups except $30^\\circ C$ was infered to be about 110 minutes after the start of experiment.

This study is an empirical research based on data analysis obtained by surveying 655 adult men and women. The notable findings are as follow: First, overall, individuals' perception of extramarital affair is negative, but about 16.4% respondents have a positive perception of it. Second, the respondents have a more critical perception of their spouse's extramarital affairs compared to their own. Thirdly, the less critical perception of extramarital affair, the more acceptance of my extramarital relationship, the less tolerance of my spouse's extramarital relationship regardless marital status. Forth, while the less tolerance of spouse's extramarital relationship, the less openness to extramarital sex among unmarried group, the more acceptance of my own extramarital relationship, the more openness to extramarital sex among married group. Lastly, individuals' perception of extramarital relationship does not directly affect the openness to extramarital sex only among unmarried group, however, the correlation between the perception of extramarital affairs and the openness to extramarital sex is fully mediated by the effect of unacceptance of spouse's extramarital affairs. The moderating effect of marital status is proved.

Background: Abdominal compartment syndrome has multiple etiologies that are not only related to trauma but also any problem condition in the absence of abdominal injury. To determine whether prevention of the abdominal compartment syndrome after celiotomy for trauma victims justifies the use of temporary abdominal coverage with monofilament knitted polypropylene mesh (Malex mesh) in severely injured patients. Method: Medical records at the Ajou University Medical Center were reviewed for a 32-month period from May 1st, 2002 to December 31st, 2004. Twenty-nine consecutive patients requiring celiotomy who were survived until at the end of celiotomy received temporary abdominal coverage and staged abdominal repairs with Malex mesh. One of them was dissecting aortic aneurysm patient and the others were all trauma victims. Malex mesh prosthesis coverage was used in cases of abdominal compartment syndrome due to excessive fascial tension, severe bowel edema and retroperitoneal hemorrhage or edema followed by staged abdominal repairs. Result: Eighteen of twenty-nine patients were survived. Demographic characteristics, injury severity number of abdominal-pelvic bone injuries, mortality rate, complications, number of operations for permanent closure, required time for permanent closure showed no difference between man and women or child and adult. Except one dissecting aortic aneurysm patient, trauma cases showed $3.24{\pm}0.98$ injury sites. All cases that received temporary abdominal coverage and staged abdominal repairs did not show abdominal compartment syndrome. $10.08{\pm}5.85$ days and $2.27{\pm}0.82$ times of operation required making permanent abdominal closure after temporary abdominal coverage followed by staged abdominal repairs. Most of surviving patients have shown antibiotic-resistant organism and fungus infection. Patients who received permanent closure recovered from infectious problem completely. Conclusion: The use of Malex mesh for temporary abdominal coverage in severely injured patients undergoing celiotomy was effective treatment method.

Objectives : This study analyzed psychological aftereffects and made comparisons between victims who were either sexually assaulted or molested using the Minnesota Multiphasic Personality Inventory-2(MMPI-2). Methods : The participants were adult women who visited the Busan Smile Center within 6 months following sexual assault. This study categorized the participants according to types of sexual violence and then identified their social demographic features and characteristics. Student's t-tests were carried out to compare the MMPI-2 results between the sexually assaulted group and sexually molested group. Chi-square tests were also conducted to compare between participants who scored above 65T. Results : Among the 55 participants, 32 were sexually assaulted; 23 were sexually molested. Significant differences between the two groups were found in the following scales: F, F(B), F(P), Pt, Sc, Ma, RC6 and PSYC. Moreover, the number of participants with higher scores in the Pa, Pt, Sc, RC6, and PSYC scales in the sexually assaulted group was significantly higher than in the sexually molested group. Conclusions : Both groups of victims may commonly suffer beyond the moderate level of depression and anxiety in the post-case term. In addition, the sexually assaulted group seems to suffer relatively more from panic and psychological pain than the sexually molested group does.

BACKGROUND/OBJECTIVE: It is expected that dairy products such as cheeses, which are the main source of cholesterol and saturated fat, may lead to the development or increase the risk of cardiovascular and metabolic diseases; however, the results of different studies are inconsistent. This study was conducted to assess the association between cheese consumption and cardiovascular risk factors in an Iranian adult population. SUBJECTS/METHODS: Information from the Isfahan Healthy Heart Program (IHHP) was used for this cross-sectional study with a total of 1,752 participants (782 men and 970 women). Weight, height, waist and hip circumference measurement, as well as fasting blood samples were gathered and biochemical assessments were done. To evaluate the dietary intakes of participants a validated food frequency questionnaire, consists of 49 items, was completed by expert technicians. Consumption of cheese was classified as less than 7 times per week and 7-14 times per week. RESULTS: Higher consumption of cheese was associated with higher C-Reactive Protein (CRP), apolipoprotein A and high density lipoprotein cholesterol (HDL-C) level but not with fasting blood sugar (FBS), total cholesterol, low density lipoprotein cholesterol (LDL-C), triglyceride (TG) and apolipoprotein B. Higher consumption of cheese was positively associated with consumption of liquid and solid oil, grain, pulses, fruit, vegetable, meat and dairy, and negatively associated with Global Dietary Index. After control for other potential confounders the association between cheese intake and metabolic syndrome (OR: 0.81; 96%CI: 0.71-0.94), low HDL-C level (OR: 0.87; 96%CI: 0.79-0.96) and dyslipidemia (OR: 0.88; 96%CI: 0.79-0.98) became negatively significant. CONCLUSION: This study found an inverse association between the frequency of cheese intake and cardiovascular risk factors; however, further prospective studies are required to confirm the present results and to illustrate its mechanisms.

Purpose - The purpose of this study is to target Chinese consumers of Korean agri-food through the analysis of agri-food brand identity images to set future directions for proposed agri-food exports to China. Since negotiations began for a free trade agreement (FTA) between Korea and China, some Koreans have worried about the Korean agriculture sector. The world trading system has undergone many changes in recent years. Since the start of FTA negotiations on agriculture, China and Korea have faced a heightened sense of crisis. China is trying to export agricultural products so actively that its agricultural exports could increase by more than 7% annually. China exported about one-tenth of its agricultural products to Korea in the period 2002-2010. Recently, the importance of brand identity has tended to increase, as the world becomes one unified market. In this situation, we should try to promote agri-food exports to China. It is very important to understand consumers' recognition of Korean food and the image of the Korean agri-food industry, to establish an export strategy. Research design, data, and methodology - This study targeted 2,800 adult men and women aged 25-59 years living in four major cities in China (Beijing, Shanghai, Guangzhou, and Qingdao) with a household income within the top 10% level in the China, using the one-to-one interview survey method. In addition, four groups by region (eight people per group) for a total of 32 groups were surveyed by using the focus group interview (FGI) research method, and impressions of imported agri-food were surveyed using 17 questions about fresh agri-food and 22 questions on processed agri-food. Factor analysis, brand positioning, biplot analysis, and so on, were carried out based on the results of these surveys. This research presents the brand identity of Korean food; according to the analyses, the brand identity is based on trust, safety, and attractiveness. Result - Factor analysis results showed that Chinese consumers expect four major qualities in imported fresh agri-food: freshness/safety, attractive appearance, premium branding, and excellent taste/quality. In the case of processed agri-food, it turned out that Chinese consumers are focused on safety/hygiene/freshness, health, and taste. In addition, in the fresh agri-food analysis by country, American foods had the upper hand; the image of American foods was also recognized as the most positive for processed agri-food. Meanwhile, according to the biplot analysis, Korean agri-food is strongly preferred for its appearance, but no country is strongly preferred as regards the level of freshness/safety that is expected by Chinese consumers. Conclusions - In this study, we analyzed the image of imported agri-food expected by Chinese consumers by reconstructing agri-food characteristics from the brand perspective. The research result shows that a Korean brand identity must be the ultimate goal for activities undertaken to enhance the image of Korean agri-food in the future. Additional research is needed because brand image can be formed through various channels.

Because the intake of vitamin A had been consistently found to be low among Koreans, there has been a concern that mild vitamin A deficiency might be prevalent in the population. However, the inaccuracy of vitamin A database has long been suspected database for the nutrient. This study was performed to assess the vitamin A and E status in 208 adults over 20 years of age living in a rural area of Korea. Newly modified database for vitamin A and E was used to estimate the dietary intake of the subjects in this study. A cross sectional survey of dietary intake with 24-hour recall method was conducted. Serum retinol and $\alpha$-tocopherol levels of the subjects were analyzed in fasting samples using HPLC. For vitamin A, mean levels of dietary intake and percent of RDA were 620.3$\pm$1087RE/day and 88.6$\pm$155.4%, respectively, which were considerably higher than the levels reported in 1995 Korean national Nutrition survey(470.1RE/day and 67.2%, respectively). For vitamin E, the levels were 9.74$\pm$6.30mg/day and 97.4$\pm$63.0%, respectively. Mean concentration of serum retinol was 83.1$\pm$30.1$\mu\textrm{g}$/dl and none of the subjects was below 10$\mu\textrm{g}$/dl, or deficient level. Mean serum retinol in men, 99.8$\pm$30.4$\mu$g/dl, was significantly higher than in women, 70.7$\pm$23.4$\mu\textrm{g}$/dl (p<0.01). Mean concentration of serum $\alpha$-tocopherol was 1.17$\pm$0.52mg/dl and that of one subject was below 0.5mg/dl, or deficient level. Serum $\alpha$-tocopherol levels of the old subjects were higher than the younger subjects in both sexes(p<0.05). These data suggest that contrary to the previous reports about low intake of vitamin a, intake and serum levels of vitamin A among the subjects are not low. Also, in this study, intake and serum levels of vitamin E are not low, either. (Korean J Nutrition 34(2) : 213~221, 2001)
