Opisthorchis viverrini is an ongoing public health problem in Northeast Thailand. Despite continuous efforts for decades by healthcare organizations to overcome this problem, infection rates remain high. To enable related personnel to identify and address the various issues effectively, a cross-sectional study was performed to investigate prevalence and risk factors for opisthorchiasis. The target group was 3,916 Thai residents of Northeast Thailand who were 15 or over. Participants were recruited using the 30 clusters sampling technique. The data were gathered through questionnaires, focus group discussions, in-depth interviews, and stool examinations for parasite eggs (using the Modified Kato Katz method). The data were analyzed using descriptive and inference statistics; in order to ascertain the risk factors and test them using the odds ratio and multiple logistic regressions. The prevalence of opisthorchiasis was 22.7% (95%CI: 0.26 to 0.24). The province with the highest prevalence was Nakhorn Phanom (40.9%; female to male ratio =1:1.2). The age group with the highest prevalence was 40-49 year olds. All age groups had a prevalence >20%. Four of seven provinces had a prevalence >20%. The factors related to opisthorchiasis were (a) sex, (b) age (especially > 50), (c) proximity and duration living near a water body, and (d) eating raw and/or fermented fish. In order to reduce the prevalence of opisthorchiasis, the focus in populations living in upper Northeast Thailand should be changing their eating behaviors as appropriate to their tradition and context.

Cities in the region have a problem in that they cannot accurately monitor small areas because the number of air pollution is differently observed depending on variables such as population, season, traffic volume, and industrial complexes. In order to solve this problem, in this paper, comparative analysis was performed on small areas where representative air pollutants SO2, PM10, NO2, CO, and O3, which adversely affect the human body, are observed through coefficient of determination. In addition, based on Bonferroni's multiple comparative analysis, the air pollution level by period is shown. The map for the monitoring system was linked with the coordinates of each small city to visualize air pollutants for small cities based on the analysis data. Through this, it is possible to provide the user with a monitoring system of air pollutants for the region more precisely, and to prevent them from accidents that may occur due to air pollution in everyday life.

Hypertension often leads to cardiovascular disease and kidney disease, and hypertention is an important worldwide problem. Body mass index (BMI) has an important role for raising blood pressure. Further, hypertension can be affected by both environmental factors and genetic factors. Many single nucleotide polymorphisms have been associated with hypertension. Genome wide association study (GWAS) is a method of confirming a new locus of increasing the risk of disease, and GWAS has confirmed several single nucleotide polymorphisms (SNPs) that are associated with high blood pressure. This study analyzed the relationship between systolic blood pressure, diastolic blood pressure and SNP of the ATP2B1 gene in 994 Koreans. SNPs that showed the highest statistical significance with systolic and diastolic blood pressures were selected on the multiple linear regression analysis. One-way analysis of variance for systolic and diastolic blood pressures was performed, and multiple logistic regression analysis was performed on the risk of hypertension. The P values were two-tailed, and P<0.05 was considered significant. Four SNPs were associated with systolic blood pressure and six SNPs were associated with diastolic blood pressure. In addition, a genotype-based analysis showed significant odds ratios for the risk of hypertension in older men (adjusted OR, 5.743; 95% CI, 1.173~28.121; P=0.031). This study suggests that the ATP2B1 variants affect both the systolic and diastolic blood pressure.

The purpose of this study was to provide the basic, data for developing a program for effective prevention for Postpartum Depression (PPD) by investigating the level of PPD in postpartum 2 weeks women. The subjects were 384 women who visited obstetrical clinics for postnatal care. The data were collected from June 29. 1999 to April. 2000, using a 46-item questionnaire related to PPD, and analyzed by SAS program for t-test, ANOVA, Scheffe test, stepwise multiple regressions. The results were as follows : 1. The level of PPD according to general characteristics Women had mild PPD (Min score; 46.0, Max score; 124.0). The PPD levels were significantly differences according to religion and marital satisfaction (p<0.05). 2. The level of PPD according to obstetrical characteristics 1) Characteristics related to pregnancy The PPD levels were significantly differences according to mood change, confidence of body weight recovery, depression related to appearance change, husband's help to housework, and husband's emotional support (p<0.05). 2) Stressful events during pregnancy The PPD levels were significantly differences according to financial problem, conflict between partners, conflict between family, and husband's job change (p<0.05). 3) Characteristics related to delivery and post natal period The PPD levels were significantly differences according to baby's health state, parenting confidence, and difficulties related to postpartum care (p<0.05). 3. The variables to predict postpartum depression in postpartum women are depression related to appearance change (10.4%), parenting confidence (8.8%), husband's help to housework (2.7%), confidence of body weight recovery (2.4%), husband's job change (1.9%), baby's health state (1.9%), difficulties related to postpartum care (1.6%), mood change (1.2%), conflict between partners (0.6%), marital satisfaction (0.5%), financial problem (0.4%). The sum total of all the above variables can account for 32.4% of postpartum depression. 4. The level of PPD according to PPD factors. Women had the highest degree of PPD in biophysiological phenomena-disturbance of physical functioning factor. The factors of relationship to baby-negative feeling and cognitive phenomena-self concept disturbance were showed the lowest degree of PPD. As a result of the above findings, a systemic and individualized program is strongly recommended for PPD prevention, diagnosis, and care for PPD in postpartum women. In near future, this study should be expanded to investigate the coping skills according to the PPD levels in postpartum women.

The purpose of this paper is to provide a search system using a method of accessing the web in real time without using a database server in order to guarantee the up-to-date information in a single network, rather than using a plurality of bots connected by a wide area network Design. The method of the research is to design and analyze the system which can search the person and keyword quickly and accurately in crepe system. In the crepe server, when the user registers information, the body tag matching conversion process stores all the information as it is, since various styles are applied to each user, such as a font, a font size, and a color. The crepe server does not cause a problem of body tag matching. However, when executing the crepe retrieval system, the style and characteristics of users can not be formalized. This problem can be solved by using the html_img_parser function and the Go language html parser package. By applying queues and multiple threads to a general-purpose web crawler, rather than a web crawler design that targets a specific site, it is possible to utilize a multiplier that quickly and efficiently searches and collects various web sites in various applications.

This study was conducted to investigate the factors related to the poor school performance of the elementary school children. Two schools in Taegu, one in the affluent area and the other in the poor area, were selected and a total of 175 children whose school performance was within low 10 percentile (poor performers) and 97 children whose school performance were within high 5 percentile (good performers) in each class of 2nd, 4th and 6th grades were tested for the physical health, behavioral problem and family background. Each child had gone through a battery of tests including visual and hearing acuity, anthropometry (body weight, height, head circumference), intelligence (Kodae Stanford-Binet test), test anxiety (TAI-K), neurologic examination by a developmental pediatrician and heavy metal content (Pb, Cd, Zn) in hair by atomic absorption spectrophotometry. A questionnaire was administered to the mothers for prenatal and prenatal courses of the child, family environment, child's developmental history, and child's behavioral and learning problems. Another questionnaire was administered to the teachers of the children for the child's family background, arithmatic & language abilities and behavioral problem. The poor school performance had a significant correlation with male gender, high birth order, broken home, low educational and occupational levels of parents, visual problem, high test anxiety score, attention deficit hyperactivity disorder (ADHD), poor physical growth (weight, height, head circumference) and low I.Q. score. The factors that had a significant correlation with the poor school performance in multiple logistic regression analysis were child's birth order (odds ratio=2.06), male gender(odds ratio=5.91), broken home(odds ratio=9.29), test anxiety score(odds ratio=1.07), ADHD (odds ratio=9.67), I.Q. score (odds ratio=0.85) and height less than Korean standard mean-1S.D.(odds ratio=11.12). The heavy metal contents in hair did not show any significant correlation with poor school performance. However the lead and cadmium contents were high in males than in females. The lead content was negatively correlated with child's grade(P<0.05) and zinc was positively correlated with grade (P<0.05). among the factors that showed a significant correlation with the poor school performance, high birth order, short stature and ADHD may be modified by a good family planning, good feeding practice for infant and child, and early detection and treatment of ADHD. Also, teacher and parents should restrain themselves from inducing excessive test anxiety by forcing the child to study and over-expecting beyond the child's intellectual capability.

Pain is a subjective and multidemensional concept. Therefore the patient's expression of pain have been referedl to the best believable indicator of pain condition but the support data obtained from the patient considered cultural difference is a deficient condition in determinded on the precise nursing diagnosis. The purpose of this reasearch was to understand multiple pain reponses in cultural difference and sensitivity, to encourage communication between medical teams, and to provide the foundation data of on data of precise nursing assessment for the patient in pain. The research problem was to grasp pain express pattern of Korean peptic ulcer patients. The subjects were 20 peptic ulcer patients in medical unit or OPD of twp university hospitals in Seoul. Data were collected from September 7th to 22nd, 1990 by intensive interviews. Interviews were done by the researcher and all were tape - recorded. The Data analysis was done by Phenomenological method from Van Kaam. Validity assured by confirmation of the internal consistency of the statements and catigory by nursing collegue in educational and clinicions in medical care. From the emic data, 96 descriptive statements were organized in 18 theme cluster. The results of study were summerized as follows. 1. Pain Express Pattern cluster of Peptic Ulcer Patients were “Pain as clogging”, “shallow pain”, “pain as pressing”, “nauseating pain”, “pain as smarting”, “pain as pulling”, “pain as pricking”, “pain as bursting”, “wrenching pain”, “excising pain”, “uncontrollable pain for mind and body”, “awakening pain”, “pain as hollowing” and the other cluster. As above mentioned, Pain Express Pattern of Peptic Ulcer Patient appeared diversely in verbal and they were propered to Korean culture. Therefore they will provide for the foundation data of precise nursing assessment.

Colorectal cancer (CRC) is a worldwide health problem, being the third most commonly detected cancer in males and the second in females. Rising CRC incidence trends are mainly regarded as a part of the rapid 'Westernization' of life-style and are associated with calorically excessive high-fat/low-fibre diet, consumption of refined products, lack of physical activity, and obesity. Most recent epidemiological and clinical investigations have consistently evidenced a significant relationship between obesity-driven inflammation in particular steps of colorectal cancer development, including initiation, promotion, progression, and metastasis. Inflammation in obesity occurs by several mechanisms. Roles of imbalanced metabolism (MetS), distinct immune cells, cytokines, and other immune mediators have been suggested in the inflammatory processes. Critical mechanisms are accounted to proinflammatory cytokines (e.g. IL-1, IL-6, IL-8) and tumor necrosis factor-${\alpha}$ (TNF-${\alpha}$). These molecules are secreted by macrophages and are considered as major agents in the transition between acute and chronic inflammation and inflammation-related CRC. The second factor promoting the CRC development in obese individuals is altered adipokine concentrations (leptin and adiponectin). The role of leptin and adiponectin in cancer cell proliferation, invasion, and metastasis is attributable to the activation of several signal transduction pathways (JAK/STAT, mitogen-activated protein kinase (MAPK), phosphatidylinositol 3 kinase (PI3K), mTOR, and 5'AMPK signaling pathways) and multiple dysregulation (COX-2 downregulation, mRNA expression).

Osteoporosis is a rising problem, as the older age population is increasing due to prolongation of life. Genetic and environmental factors play key roles in bone metabolism, and diet is also an important factor. We investigated the relationship among factors affecting bone mineral density (BMD), including daily food intake and nutrient intake in men aged >50 years. Seventy-eight men, who visited the health promotion center at one of the university medical centers, were divided into normal and osteopenia groups according to their BMD. The body weight of the normal group was significantly higher than that of the osteopenia group. The osteopenia group showed significantly higher carbohydrate intake and lower calcium and vegetable calcium intake compared to those in the normal group. Lumbar spine BMD was negatively correlated with energy, fat, vitamin B1, and sodium intake in the normal group. Additionally, femoral neck BMD was negatively correlated with total animal protein, energy, protein, fat, phosphorous, iron, animal iron, potassium, vitamin B1, B2, B6, and niacin intake. Lumbar spine BMD was positively correlated with fruit, calcium, vegetable calcium, animal calcium, and vitamin C intake in the osteopenia group. Femoral neck BMD was negatively correlated with meat, dairy product, total animal protein, plant protein, animal protein, vitamin A, and cholesterol intake. A stepwise multiple regression analysis revealed that several dietary factors affected BMD, including energy, fat, vitamin B1, B2, B6, niacin, sodium, protein, iron, animal iron, phosphorous, potassium, and animal protein in the normal group and zinc, calcium, vegetable calcium, animal calcium, vitamin C, fruit, protein, animal protein, meat, dairy product, carbohydrates, cholesterol, vegetables, mushrooms, and seasonings in the osteopenia group. These results indicate that adequate nutrient intake plays an important role maintaining optimum bone health in middle aged men.

Statement of problem. Use of the conventional dental impression procedure is problematic in patients who have difficulty opening their mouth, difficulty breathing through their nose or tendency to gag. Purpose. It is necessary to make individual trays more comfortable for patients during impression taking procedure. It was reported at the KAP Annual Meeting 2001 Seoul that an improved impression technique was suitable for this purpose. In this study, the accuracy of the improved dental impression method for implant was compared with the conventional dental impression method. Material and methods. An oral simulator was made from clear acrylic resin block which had similar form of edentulous ridge. For setting up the standard, five fixtures were installed on it. Study casts were made using two kinds of impression techniques. One was the conventional method that was taken using silicone impression material and an individual resin tray under connection of inter-fixture relation. The other was the improved method in which was the connection of the impression coping and the thermoformed polymethyl methacrylate tray. In addition, two different study casts were made from the improved impression body. The coordinates of the fixture on the study model were measured by three-dimensional coordinate measuring equipment. Then the distances between each fixture were calculated and compared with that of oral simulator. Accuracy of the each impression method was also assessed. Results. The differences of inter-fixture dimension between study casts and simulator in the improved impression technique showed $0.014{\pm}0.016mm$ and $0.017{\pm}0.022mm$, respectively and that of the conventional method was $0.017{\pm}0.014mm$. There was no significant difference between the improved impression technique and conventional method. Conclusion. The improved impression technique is useful for multiple support implants.
