  • On community data. sampled in regular intervals on a long-term basis. artificial neural networks were implemented to extract information on characterizing patterns of community changes. The Adaptive Resonance Theory and Kohonen Network were both utilized in learning benthic macroinvertebrate communities in the Soktae Stream of the Suyong River collected monthly for three years. Initially, by regarding each monthly collection as a separate sample unit, communities were grouped into similar patterns after training with the networks. Subsequently, changes in communities in a sequence of samplings (e.g., two-month, four-month, etc.) were given as input to the networks. After training, it was possible to recognize new data set in line with the sampling procedure. Through the comparative study on benthic macroinvertebrates with these learning processes, patterns of community changes in chironomids diverged while those of the total benthic macro-invertebrates tended to be more stable.

  • The clustering of insulin resistance with hypertension, glucose intolerance, hyperinsulinemia, increased triglyceride and decreased HDL cholesterol levels, and central and overall obesity has been called syndrome X, or the insulin resistance syndrome(IRS). To develop a nutrition service for IRS, this study was performed to evaluate the prevalence of each component of the metabolic abnormalities of IRS and analyze the clustering pattern of IRS among subjects living in the Taegu community. Participants in this study were 9234(mean age ; M/F 48/40yrs);63.5% were men, 24.4% were obese, 13.3% had hypertension. 3.7% had hyperglycemia, and 32.4% had hyperlipidemia. The IRS was defined as the coexistence of two or more components among metabolic abnormalities; obesity, hypertension. hyperglucemia and hyperlipidemia. The prevalence of IRS in Taegu was 19.2%(M/F:20.8%/16.4%), the clustering of these fisk variables was higher in advanced age group. Among the subjects of IRS having two of more diseases, 75.6% were obese, the pattern were similar in men and women. The younger, the higher the prevalence of obesity associated clustering patterns. The prevalence of obesity associated patterns among the hyperglycemia associated clustering patterns was 44.5%. The samples of the representative clustering patterns were obesity and hyperlipidemia (8.0%), hypertension and hyperlipidemia(3.2%), hypertension, obesity and hyperlipiemia(3.1%), hypertension and obesity(2.3%), and hyperglycemia and hyperlipidemia(0.8%). The clustering of obesity and hyperlipidemia until 50 year old groups, and the clustering of hypertension and hyperlipidemia in the 60 and 70 age groups were the most prevalent. We concluded that insulin resistance syndrome was a relatively common disorder in the Taegu community, and prevalence and the characteristics of the intervention strategies for IRS are desired, an effective improvement will be achieved.

  • Korea has not tried any food consumption survey so far except the national nutrition survey, which does not show food consumption patterns of different income stratas. The results of the family income and expenditure survey(FIES) by the national statistical office can be precious sources which show household food consumption patterns due to large, random. Samples, year-round survey period and socioeconomic background data. This study analyzed the FIES data to find out food consumption patterns including nutrient intakes and frequently consumed foods by households among different monthly income levels. Big difference was found in food consumption patterns among the quartile-income groups especially the amount of consumed foods, food expenditure, and nutrient intakes. For every food item, the higher the monthly invomr, yhr motr og goof yhry vondumrf. The monthly food expenditure of higher higher income strata was composed with higher percentage of relatively expensive foods compared to other stratas. Nutrient intake levels of lower income strata were 50-60% of the RDA, which showed the necessicity of food assistance programs for those high risk groups to complement the nutritional difficiency.

  • The purpose of this study is to figure out the trends of the community facilities patterns in the designated apartments through the method of analyzing a case of a community housing yet to be open to its tenants. The thesis is based on document research and analysis of apartments categorized into five different groupings all in a status of being a prospective dwelling. The conclusion of the case study results as follows. Firstly, the distribution of a plan is either centrifugal or widespread. Secondly, the elevation plan contains its facilities in the basements or low-rise floors. Thirdly, sports facilities such as an indoor driving range, a fitness club and a GX-room and a open square on the outer space were unifiably common to all five groupings. In conclusion, in light of the facility patterns shown in the five extracted groupings of apartments, it seems that it will be difficult for all residents to benefit from the public facilities because the facilities are perceived as being limited to only a specific tower which hampers the improvement of the quality of life of the rest of the tenants and dampens an active social gatherings. Therefore, the public facilities must be planned and constructed to meet the satisfaction of the residents in whole, in place of being a commercially lucrative space.

  • We compared the antimicrobial resistance and clonal relationships among the community-acquired (CA) and hospital-acquired (HA) methicillin-resistant Staphylococcus aureus (MRSA) strains that were isolated from blood cultures in a university hospital over a 4-year period. A total of 131 MRSA isolates, including 28 CA-MRSA and 103 HA-MRSA strains, were identified; antimicrobial susceptibility testing indicated that the CA-MRSA isolates were more susceptible to erythromycin (21 % vs 6% ; P=0.02), clindamycin (46% vs 12%; P<0.01), ciprofloxacin (43% vs 11%; P<0.01), and gentamicin (43% vs 6%; P<0.01) than were the HA-MRSA isolates. Pulsed-field gel electrophoresis (PFGE) typing and antimicrobial resistance profiles separated the 20 CA-MRSA isolates into 14 and 10 different patterns, respectively, and the 53 HA-MRSA isolates were separated into 24 and 7 different patterns, respectively. Twenty-one (40%) of the 53 HA-MRSA isolates belonged to two predominant PFGE types, and most of them showed multi-drug resistant patterns. Four (20%) of the 20 CA-MRSA and 10 (19%) of the 53 HA-MRSA isolates fell into two common PFGE patterns, and each of them showed the same multi-drug resistant pattern. This study suggests that, although the CA-MRSA blood isolates showed diverse PFGE and antimicrobial resistance patterns, some of these isolates may have originated from the HA-MRSA strains.

  • The purposes of this study are to identify types of fathers who engaged in different patterns of interaction with their children and to examine the characteristics by different fathering patterns. Data are collected from 323 married men with the oldest child under 12 years old, using the structured questionnaire survey method. The major findings of the study are as follows: First, the fathering activities are composed of four factors, which are affective involvement, caretaking, social involvement and discipling. The respondents tend to exhibit the level of fathering activities higher than middle point. Second, using cluster analysis, three types of fathers are categorized: The affective type fathers scored significantly high on dimensions of affective involvement. Whereas the engaged fathers scored the highest on all domains of fathering, the disengaged fathers demonstrated significantly limited involvement. Third, the characteristics which are associated with fathering activities patterns are father's age, job type, work hour, frequency of meetings after work hour, job satisfaction and child rearing attitude. The results of this study suggest several implications to develop parent education program for fathers and their children.

  • Even through many professional organizations increasingly use Q&A sites in their online communities for information sharing, there are few studies which examine what is really going on in the Q&A activities in professional online communities (POC). This study aims to examine the interaction patterns and contents posted in the Q&A site of a POC, KOSEN, a science and technology online community in South Korea, focusing on how actively scientific information and knowledge are shared. The interaction patterns among the participants were identified through social network analysis (SNA) and the contents in the Q&As were examined by content analysis. The results show that the overall network indicated a moderate level of participation and connection and answerers especially tended to be active. Also, there are different interaction patterns depending on academic fields. Relatively few participants were posting leaders who seemed to steer the overall interactions. Furthermore, some content related to manipulation and explanation for experiments, which are in urgent need, seem to be posted in the sites more frequently with more amounts. Combining both SNA and content analysis, this study demonstrated how actively information and knowledge is shared and what types of contents are exchanged. The findings have practical implications for POC managers and practitioners.

  • This study was conducted to define dietary patterns among 227 Korean American adults and 151 teenagers living in California using frequency of intake of major food groups and to examine associations of dietary patterns with selected demographic and acculturation variables. Three dietary patterns, 'healthful', 'Korean', and 'western', were identified using factor analysis. For both groups, 'healthful' pattern was characterized by high loading on milk/milk products, fruit, fruit juice, and bean/bean products. 'Korean' pattern had high loading on rice and kimchi. 'Western' pattern was characterized by high loading on meat/meat products, soda, and noodle/pasta. Among Korean American adults, women tended to have higher scores of 'healthful' pattern but lower scores of 'western' pattern, while there was no association of 'Korean' pattern with gender. The older adults were likely to have higher 'Korean' pattern score. Length of stay in the US and English levels were negatively associated with 'Korean' pattern. Korean American female adolescents had lower 'western' pattern scores than did male adolescents. Age was inversely associated with 'healthful' pattern in adolescents. The adolescents who had felt more proud of being a Korean descendant had higher scores on 'Korean' dietary pattern. The study findings support that dietary patterns are associated with acculturation variables such as length of residence in the US, English fluency, and particularly pride in ethnicity for adolescents. Further studies are needed to understand associations of dietary patterns and acculturation with health risk of ethnic groups.

  • Purpose: This study was conducted to investigate community health practitioners' knowledge of, use patterns of, and attitudes toward CAM. Method: The subjects of this study were 817 community health practitioners (CHPs) from 9 Provinces in Korea selected through convenient sampling. They completed and submitted self-report questionnaires at the annual meeting of CHPs or sent completed questionnaires to us by mail. Result: Of the CHPs, 8.1% had a certificate of CAM-related education program, and 39.9% worried about the efficacy of CAM. They knew about massage (74.0%), finger pressure (68.1%), hand acupuncture (67.8%), diet (65.5%) and herb (64.7%). They had used herb (43.3%), massage (36.8%), hand acupuncture (32.7%) and vacuum (31.2%) with positive effects and recommended residents to use them. Attitude toward CAM tended to be positive in those with certificates of CAM, those with high academic qualification, those aged 40 or below, and those working in Chungcheong-do. Conclusion: This study showed that CHPs were interested in CAM while they worried about the therapeutic effects of it. Further studies to draw cross-sectional and national data on the use patterns of CAM from the various population and standardized instruments to investigate the types of CAM were suggested.
