The aim of this study is to delve deeper into the online brand community study. This study tests (a) the effects of online brand community on its outcomes, (b) the impact of value creation practice construct as a whole, (c) the effects of value creating practice construct on the two types of loyalty, loyalty toward the brand and the community. Participants of this study (N=353) are members of four types of online brand communities (e.g., business-to-consumer virtual product support community, firm-hosted online community, user-generated online community, peer-to-peer problem-solving community, and social media based brand community). Data were collected online using Amazon Mechanical Turk from April 10, 2016 to May 10, 2016. The data were analyzed through structural equations modeling using AMOS 20. The three community markers (e.g., consciousness of kind, rituals and traditions, and moral responsibility) and the four value creation practices (e.g., social networking, impression management, community engagement, and brand use) are proved to be significant indicators of online brand community and value creation practice constructs, respectively. Test results showed that strong and effective online brand communities generate value creation practices, and value creation practices enhance brand loyalty. The mediating effects of community loyalty between value creation practices and brand loyalty were revealed.

The seasonal and spatial diversity of picocyanobacteria (Pcy) in lakes of the Great Mazurian Lakes (GLM) system was examined by DGGE analysis of molecular markers derived from the 16S-23S internal transcribed spacer (ITS) of the ribosomal operon and the phycocyanin operon (cpcBA-IGS). The study of nine lakes, ranging from mesotrophy to hypereutrophy, demonstrated seasonal variance of Pcy. The richness and Shannon diversity index calculated on the basis of both markers were higher in spring and lower in early and late summer. No statistically significant relationships were found between the markers and trophic status of the studied lakes or Pcy abundance. There were, however, statistically significant relationships between the diversity indices and sampling time. The analysis pointed to a different distribution of the two markers. The ITS marker exhibited more unique sequences in time and space, whereas a greater role for common and ubiquitous sequences was indicated by the cpcBA-IGS data. Examination of the Pcy community structure demonstrated that communities were grouped in highly similar clusters according to sampling season/time rather than to the trophic status of the lake. Our results suggest that time is more important than trophic status in shaping the diversity and structure of Pcy communities. The seasonal changes in picocyanobacteria and differences in diversity and community structures are discussed in the context of well-established ecological hypotheses: the PEG model, intermediate disturbance hypothesis (IDH), and horizontal gene transfer (HGT).

In our country, cardiovascular disease (CVD) and Coronary heart diseases (CHD) are the leading causes of death. It is well known that CHD is multifactorial, involving environmental factors such as diet, level of exercise and cigarette smoking, and inherited factors. According to the statistical data in 2003, the cause of death with the highest mortality was including hypertension, ischemic heart disease and atherosclerosis, which accounted for $24.7\%$ of total mortality. In spite of, there have been few study reports on the change of biochemical markers and mechanisms concerned. The development of biochemical markers is required for an early diagnosis and treatment of cardiovascular diseases that are related with dietary habits of Korean people enjoying mixtures of traditional dietary style and westernized food-styles. Therefore, the most efficient cost-saving biochemical marker was established in this study, through analysis of biochemical markers related with dietary habits which are susceptibly being changed in association to cardiovascular diseases from the pre-disease phase, and through reanalysis and assessment of early diagnosis of and preventive effects of diagnosis of cardiovascular diseases by demographical character including sex, age, and socioeconomic level with use of biochemical markers that are identified and selected among the parameters in consideration of the effectiveness and appropriateness of early diagnosis of diseases. The appropriateness of biochemical markers was reviewed by professionals (medical, pharmaceutical area and food/ nutrition area) and CRP(C-Reactive Protein) and was identified to be possible in Korea. It is thought that these biochemical markers may be used as the basic data for early diagnosis and prevention of cardiovascular diseases (CVD) which may be used for Korean people.

Purpose: This study was undertaken to explore sex differences in the risk markers of cardiovascular disease (CVD) and psychosocial factors and the relationships among these variables for the community-residing adults. Methods: A cross-sectional study was conducted with a total of 114 participants consisting of 65 men aged 42.85 years old and 49 women aged 46.86 years old. Participants were selected by a convenient sampling of at community cultural centers and churches. They completed a structured questionnaire including demographic characteristics, physiologic risk markers of CVD; lifestyle factors; and depression, social support, and stress. Results: The male participants showed significantly higher systolic and diastolic blood pressures than their counterparts. Significantly higher percent of women were currently non-smokers, and practiced moderate alcohol intake, physical activity, and low fat diet. Among women, the higher the scores of depression and stress were and the lower that of the social support was, the higher blood pressure, waist circumference and BMI were. Among men, those who were less depressed and with higher scores of social support had more physical activity. Conclusion: The findings suggest further studies to explore sex differences of CVD risk markers and psychosocial factors, and their relationships in a larger sample, and to find the mechanism underlying these differences with a prospective design.

To delineate the relationship between the nutrient intake from diet and the serum biochemical markers of bone metabolism, 56 postmenopausal women of 50 to 77 years of age were recruited. The biochemical markers including osteocalcin, calcium, phosphorus, estradiol and free testosterone were measured in fasting blood. Bone mineral density(BMD) was measured also by dual energy X-ray absorptiometry, and the nutrient intake of earth individual subject was estimated by 24-hour recall of 3 days. The age of the subjects was 64.8 $\pm$ 7.7 years, and the BMDs of the subject were 0.86 $\pm$ 0.26g/$cm^2$(Lumbar spine), 0.60 $\pm$ 0.10g/$cm^2$ (Femoral neck), 0.49 $\pm$ 0.10g/$cm^2$(Trochanter), and 0.41 $\pm$ 0.14g/$cm^2$(Ward's triangle). There were no significant differences among age and nutrient intake level groups due to the small sample size. The biochemical markers showed certain degree of relationship with nutrient intake levels. The results were compared among 3 groups with different nutrient intake level classified by the percentage of Recommended Daily Allowances(RDA) for Koreans as follows low < 75% RDA, 75% RDA $\leq$ adequate < 125% RDA, high $\geq$ 125% RDA. The low energy and low riboflavin groups showed significantly higher serum osteocalcin levels than those of the high intake groups(p < 0.05). On the other hand, there was a trend for serum Ca level to be higher with high nutrient intake. In this case, protein and thiamin were the only nutrients that reached a statistical significance(p < 0.05). And the groups with low intake for protein and Ca showed significantly lower serum free testosterone levels than that of other intake groups(p < 0.05). This study suggests an important role of nutrient intake levels on blood biochemical markers of bone metabolism.

To evaluate the possible route of intrafamilial transmission among carriers of hepatitis B surface antigen ($HB_sAg$), epidemiologic and serologic data were obtained on 107 household contacts of 35 carriers of HBsAg and on 71 household contacts of 25 controls who were negative for serologic markers of hepatitis B virus. The HBsAg prevalence was 26.5% among the contacts of carriers compared to 0.0% among the contacts of controls. And the combined prevalence for all hepatitis markers was 48.5% among the contacts of carriers compared to 26.0% among the contacts of controls(p<0.05). Especially the offspring of carriers showed significantly higher risk in the combined prevalence for all hepatitis markers (p<0.05). There were no significant relationship between HBV infection and past history like acupuncture, transfusion, operation and tattooed. Factors associated with the risk of intrafamilial transmission of HBV were not found in the sharing of household articles such as razor, towel, drinking glass, nail clippers, toothbrush and tableware.

This review provides a comprehensive summary of the PCR primers and profiles currently in use in our laboratory for red algal DNA barcoding and phylogenetic research. While work focuses on florideophyte taxa, many of the markers have been applied successfully to the Bangiales, as well as other lineages previously assigned to the Bangiophyceae sensu lato. All of the primers currently in use with their respective amplification profiles and strategies are provided, which can include full fragment, overlapping fragments and what might best be called "informed overlapping fragments", i.e., a fragment for a marker is amplified and sequenced for a taxon and those sequence data are then used to identify the best primers to amplify the remaining fragment(s) for that marker. We extend this strategy for the more variable markers with sequence from the external PCR primers used to "inform" the selection of internal sequencing primers. This summary will hopefully serve as a useful resource to systematists in the red algal community.

Purpose: This study was conducted to evaluate the socioeconomic status as a risk factor for hepatitis C virus infection among community-dwelling adults in Korea. Methods: This study was a cross-sectional study including 2,617 adults. Data from hepatocellular carcinoma epidemiological investigation and information regarding three markers of socioeconomic status, education, employment, household income, were obtained. Multiple logistic regression was performed to calculate odds ratios (ORs) for hepatitis C virus infection for socioeconomic status markers, adjusting for the other soioeconomic status marker, behavioral and hepatitis-related factors. Results: Of the 2,617 study subjects, 104 subjects infected with hepatitis C virus and prevalence was 4%. When compared to subjects with a lowest education, ORs was 0.16 (95% confidence interval [CI]: 0.04-0.69) for highest education group. After adjusting behavioral and hepatitis-related factors, ORs was 0.20 (0.05-0.87) for highest education compared with lowest group. Conclusion: Low educational level was associated with an increased risk of hepatitis C virus infection.
