The Objectives: The purpose of this study is to identify the factors related to management of DM in Korea. Methods: The subjects selected by using data of National Health and Nutrition Survey(NHANS) in 2005 were 415 adults, aged 20 and older, and diagnosed with DM. This study used data mining algorithms. This study validated the predictive power of data mining algorithms by comparing the performance of logistic regression, decision tree, and Neural Network on the basic of validation, it was found that the model performance of decision tree was the best among the above three techniques. Result: First, awareness of DM was positively associated with age, residential area, and job. The most important factor of DM awareness is age. Awareness rate of DM with 52 age over is 76.1%. Among the ≥52≥52 age group, an important factor is family history. Among patients who are 52 years or over with family history of DM, an important factor is job. The awareness rate of patients who are 52 age over, family, history of DM, and professionals is 95.0%. Second, treatment of DM was also positively associated with awareness, region, and job. The most important factor of DM treatment is DM awareness. Treatment rate of patients who are aware of DM is 84.8%. Among patients who have awareness of DM, an important factor is region. The awareness rate of patients who are aware of DM in rural area is 10.4%. Conclusion: Finally, the result of analysis suggest that DM management programs should consider group characteristic of DM patients.

Objectives: The purpose of this study was to examine the health promoting lifestyle(HPL) practices and to provide the baseline data for development of church setting-centered health promotion program. Methods: For the study, 315 adults were selected from a church in G city by convenient sampling method. The data were analyzed using frequencies, ANOVA, t-test, Duncan test, and Pearson's correlation coefficient with the SPSS/PC program. Results: The mean score on HPL was 3.3. The item of the lowest score HPL was smoking. In the mean score of knowledge, behavior, and practice on HPL, the highest score of knowledge on HPL was drinking, but the highest score of practice was smoking. On the other hand, the highest score of behavior was: exercise, nutrition, stress respectably. Analysis of HPL according to the demographic characteristics showed there was a statistically significant difference by age. Subcategories of HPL showed positive correlations statistically significant: Exercise with nutrition, stress and drinking. Nutrition with stress and drinking. Drinking with stress and smoking. Conclusions: Based on the above findings, it is suggested to develop church setting-centered health promotion program with areas focused on management of stress, antismoking, sobriety, practice in nutrition and exercises.

Two major sex pheromone components (Z-8-dodecenyl acetate and E-8-dodecenyl acetate) are known in the peach fruit moth, Grapholita molesta. From a putative biosynthetic pathway of these sex pheromone components, delta 10 desaturase (10Δ10Δ DES) has been proposed to play a crucial role in synthesizing a species-specific stereoisomer of the double bond. However, its molecular identity was not known. This study determined a putative desaturase (Gm-comp1575) as a 10Δ10Δ DES candidate from G. molesta transcriptome constructed from the sex pheromone gland. Its open reading frame encodes 370 amino acid sequence with a predicted molecular weight at 43.2 kDa and isoelectric point at 8.77. It was predicted to have four transmembrane domains and six glycosylation sites at N-terminal or cytosolic domains. A phylogenetic analysis with its predicted amino acid sequence indicated that Gm-comp1575 is closely related with known 10Δ10Δ DES genes of other insects. Gm-comp1575 transcript was detected in female adults at sex pheromone gland and other abdominal tissues. RNA interference of Gm-comp1575 significantly reduced attractiveness of virgin females in apple orchard compared to control females. These results suggest that Gm-comp1575 is associated with sex pheromone biosynthesis of G. molesta.

Background: Many studies focus on the causes of depression, but few assess the dietary intake. This study investigated the relationship between diet and prevalence of depression. Methods: This study used the data from the Korea National Health and Nutrition Examination Survey 2010. A total of 734 persons aged 20-65 years old in whom the presence or absence of depression was confirmed by doctor were analyzed. We analyzed associations between prevalence of depression and diet based on carbohydrate, fiber, calcium, iron, sodium, potassium, vitamin A, thiamine, riboflavin, niacin and vitamin C intakes for male and female groups. Results: There was no association between diet and prevalence of depression in the male group. For the female group, as fiber intake was increased, the prevalence of depression significantly decreased (odds ratio=0.923, 95% confidence interval=0.850-0.986), but there was no association between the other dietary intakes and prevalence of depression. Conclusion: The fiber intake and prevalence of depression are negatively correlated in women aged 20-65 years. A diet therapy including fiber may decrease the prevalence of depression.
To examine the relationship between the causal infection of gastric cancer and lifestyle and nutritional status, we surveyed 183 persons, 102 female and 81 male, aged 40 years and over from August to October, 1996, in Chunchon area, Kang Won Do, Korea. For this purpose, we investigated Helicobacter pylori infection in the agricultural Korean adult and identified the effect of sex, age, smoking, alcohol consumption, economic status, occupation and lifestyle. Helicobacter pylori immunoglobulin G(IgG). Helicobacter pylori infection was present in 64.5% of total subjects, and 63.7% of female, 65.4% of male and its prevalence was increased with age, smoking, low education level, low monthly income, high childbirth. Some nutrients intakes were significantly difference between Helicobacter pylori infection positive(+) group and those negative(-) group. The negative Helicobacter pylori infection group were much more intaked energy, total protein, total fat(p<0.05), animal fat(p<0.05), Iron(p<0.001), vitamin A(p<0.01), vitamin C(p<0.05) than Helicobacter pylori positive infection group. But the calcium intakes were lower than positive(+) group.

In spite of the world-wide increase of incidence of pesticide poisoning due to greater use of pesticides, the epidemiological study of pesticide poisoning in Korea has been grossly neglected. The author gained access to the medical records for two year period (1981 through 1982) from local clinics, hospitals and health centers of Kyungpook area to investigate the status of the pesticide poisoning. During these two years, there were 1,618 cases of documented pesticide poisoning, of which in 1981 were 765 and in 1982 were 853. Those in the twenties decade of age was the most frequent and the male(70%) was more liable than the female (30%). In view of manner of poisoning, occupational poisoning was 27.8%, accidental 5.6%, and suicidal 66.6%. There are three distinct groups which make up the large majority of both fatal and nonfatal cases; young children who accidentally ingest pesticides, young to middle age adult who are occupationally poisoned, and middle age to older adults who suicidally ingest pesticides. The seasonal distribution of these poisonings disclosed the peak month to be July, with August next, followed by June and September. Only 11% of cases occurred during the three-month winter season of December to February. Thus pesticide caused poison- ing was primarily a summer and early fall occurrence. During these two years, average of 67 cases of poisoning was observed monthly. Of the pesticide poisoning documented, 49% were treated with poisoning patients from local clinic and 43% from hospital. The case fatality rate of occupational poisoning was 0.9%, accidental 5.6% and suicidal 20.3%. The mean overall case fatality rate was 14.1%. Annual incidence of pesticide poisoning was 25.4 per 100,000 population in the study area. There is a nationwide need for more reliable date on pesticide poisoning. This need can only grow more acute with the passage of time because of the increasing importance of pesticides as a cause of morbidity and mortality.

Objectives: This study aimed to identify the relationship among health-related quality of life of the Cheon-nam region elderly with low back pain. Methods: Data were obtained from cross-sectional surveys conducted as a part of the Community Health Survey 2008. The final analysis included data from 7,003 of the 7,070 elderly participants (aged over 65 years), as 67 responses were excluded since they were inaccurate. Data were analyzed with SPSS for Windows (ver. 19.0), using a χ2χ2-test, a t-test, an ANOVA, and multiple liner regression. The significance threshold was set as p<0.05. Results: Factors related to the health-related quality of life of the elderly were low back pain, age, education level, occupation, subjective health status, subjective stress, drinking status, number of chronic diseases, and sleep duration. Further, health-related quality of life was significantly lower in elderly adults with low back pain. Conclusions: In order to improve health-related quality of life of the elderly and the development of the program for the management of low back pain will be needed to determine, it is considered necessary to study more to follow through the various analysis of in the elderly and health-related quality of life.
Using Random Sampling, the authors measured the body heights and weights of 31,151 persons - 17,102 in males and 14,049 in females from metropolitan, urban and rural areas between 6 to over 80 year old - for the purpose of investigating the type and the actual condition of the Korean's growth and development. At first, on the basis of the results, the authors measured the growth and development, various kinds of physiques, nutritional index of the 6 to 20s age group. Second, the authors presented the standard body weight of males and females by their body height, who were in the end of their growth (20-29 age group). Third, the authors calculated and presented the normal adapted body weight of the age group who were over 30 age after the growth had been completed. Forth, the author presented the obesity rate of the adults over 20 years old by body mass index. Finally, the authors compared chronological change of the Koreans' body heights and body weights with the results of other researchers. 1. Body Measurement Rapid growth, in terms of body height, which is described by a straight line on a growth curve has been observed among males in the ages 6-13 and among females 6-14. That growth curve turned out to be slower among the people of higher ages by both sexes. The cross-over occurred in both sexes at 11-14. The highest growth rate for a year is at 13-16 for males and 11-13 for females. This indicates that females enter a rapidly growing stage 2 years earlier than males. 2. Various Physiques and Nutritional Index Rapid growth, in terms of Relative Body Weight Index, which is described by a straight line, has been observed among males in the ages 6-16 and females in the ages 6-14. The cross-over occurred in both sexes 12.5-14.5 age in the adolescencent period. Whereupon females outgrow males. The Roher Index displayed more good value in case of females than male and in the adolescent period, the level of fullness is lower than after the completion of development. The Kaup Indices of both sexes increase with age. The index is less than 2.0 for males in 6-14 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state4 age group and for females in 6-13 age group and with this, it appeared that development of horizontal axis to long axis is poor. The index is more than 2.0 after 15 age group in males and 14 age group in females and developmental state Body Mass Index is less than 20 for males 6-14 age group and for females in 6-13 age group. In the case of the higher age group, that index maintains a normal state.
Recently, dietary pattern analysis was emerged as an approach to examine the relationships between diet and risk of chronic diseases. This study was to identify groups with population who report similar dietary pattern in Korean genome epidemiology study (KoGES) and association with several chronic diseases. The cohort participants living in Ansung and Ansan (Gyeonggi province) were totally 10,038. Among those, 6,873 subjects with no missing values in food frequency questionnaire were included in this analysis. After combining 103 food items into 17 food groups, 4 dietary factors were obtained by factor analysis based on their weights. Factor 1 showed high factor loadings in vegetables, mushrooms, meats, fish, beverages, and oriental-cereals. Factor 2 had high factor loadings in vegetables, fruits, fish, and factor 3 had high factor loadings in cereal-oriental, cerial-western and snacks. Factor 4 showed positive high factor loadings in rice and Kimchi and negative factor loadings in mushrooms and milk and dairy products. Using factor scores of four factors, subjects were classified into 3 clusters by K-means clustering. We named those 'Rice and Kimchi eating' group, 'Contented eating' group, and 'Healthy and light eating' group depending on their eating characteristics. 'Rice and Kimchi eating' group showed high prevalence in men, farmers and 60s. 'Contented eating' group and 'Healthy and light eating' group had high prevalence in women, people living in urban area (Ansan Citizen), with high-school education and above, and a monthly income of one million won and more. 'Contented eating' group appeared lower distribution proportion in the sixties and 'Healthy and light eating' group does higher in the fifties. 'Contented eating' versus 'Rice and Kimchi eating', odds ratio for hypertension, diabetes, metabolic syndrome and obesity significantly decreased after adjusting age and sex (OR=0.64, 0.73, and 0.85 respectively, 95% CI). Although our results were from a cross-sectional study, these imply that the dietary patterns were related to diseases.

We analyzed the variation in occurrence time and intensity of attacks by the rice stem borer (Chilo suppressalis Walker) on several crops. This study aimed to understand how C. suppressalis damages crops and to utilize this basic data for the establishment of environment-friendly control methods like pheromone traps. This study surveyed the changes in occurrence patterns of C. suppressalis, biological characteristics of overwintering larvae, and the efficacy of different types of pheromone traps the years. We found similar occurrence patterns of C. suppressalis in different crops. In addition, occurrence time of the first generation was advanced. Overwintering larvae showed no difference in pupal period and weight compared to the non-overwintering ones. However, the larval period was reduced to 19.1 days in Miscanthus field, in contrast to that in the paddy fields. It was confirmed that larvae of C. suppressalis generally prefer the lower part of the stems of Miscanthus. Efficiency of the emergence trap was confirmed to be greater than that of the delta trap for capturing C. suppressalis adults. However, it is necessary to adjust the control period because of the advancement in occurring time of C. suppressalis in recent years. The larvae of C. suppressalis experience favorable environmental conditions for overwintering in Miscanthus fields. The major Miscanthus fields are generally located in the areas protected for sources of drinking water, owing to which spraying of chemical pesticides is very limited. The results of this study provide important inputs for the development of environment-friendly control methods.
