Purpose - This study is based on the Theory of Planned Behavior and aims to explore the decision-making mechanisms of consumers participating in value co-creation activities within virtual brand communities. Methodology - The research involved a comprehensive survey of 405 participants from various virtual brand communities. Structural Equation Modeling (SEM) was used for data analysis, applying SPSS and AMOS to test the hypotheses. The study focused on community rules and regulations, community experience and community trust. Results - The research found that community rules and regulations significantly impact subjective norms and perceived behavioral control, but not directly influence consumer attitudes. Community experience positively affected consumer attitudes, subjective norms and perceived behavioral control. Community trust was found to positively influence these aspects of consumer decision-making. However, a gap was identified in the direct influence of perceived behavioral control on actual consumer behavior. Implications - The findings of this study contribute to a more comprehensive understanding of factors affecting consumer behavior in virtual brand communities. It underscores the necessity for community managers to develop strategies that consider these internal decision-making mechanisms, facilitating more effective community engagement. The study also identifies a potential area for future research in the direct influence of perceived behavioral control on actual consumer behavior.

Purpose: This study was conducted to investigate the effects of a community-based death education program for older adults. Methods: The study was conducted as a quasi-experimental study with a non-equivalent control group and pretest-posttest design. The subjects were community elders aged over 65 registered at a community health center and were convenience sampled. The experimental group consisted of 33 participants and the control group consisted of 32 participants. Experiments are conducted from June 18 to July 24, 2020. We tested our hypothesis using an independent t-test, and paired t-test. Results: The experimental group had significantly higher scores for psychological well-being than the control group after treatment (t=2.24, p=.028). In general attitude toward the use of life-sustaining technology, however, only the experimental group had a significant difference before and after the experiment with lower scores compared to the control group (t=-5.41, p<.001). Conclusion: We found that the community-based death education program developed in this study was partially effective in improving older adults' psychological well-being and general attitude toward the use of life-sustaining technology.

Purpose: To identify the effects on tuberculosis mortality of a tuberculosis control program conducted at 108 community health centers in terms of structure and process. Methods: The dependent variable was tuberculosis mortality, and the independent variables were the structure(type of centers, staff, nurses, doctors, budget) and process(chest X-ray checking, immunization, case detection, health education, patients registering & managing) of the tuberculosis control programs at the community health centers. Data were analyzed using descriptive analysis and stepwise regression analysis. Result: Tuberculosis morality was positively correlated with type of centers(rural area)(p<0.01), but negatively correlated with type of centers(large cities) (p<0.01), (middle cities)(p<0.05), staff FTE(p<0.05), and number of nurses(p<0.05). Regression analysis indicated that type of centers(rural area)($\beta$=0.457) and case detection($\beta$=0.234) had a significant effect on tuberculosis mortality. Conclusion: Ultimately, this study will provide information to improve the effectiveness of tuberculosis control programs in community health centers.

Knowledge on the functional characteristics and temporal variation of anaerobic bacterial populations is important for better understanding of the microbial process of two-stage anaerobic reactors. However, owing to the high diversity of anaerobic bacteria, close attention should be prioritized to the frequently abundant bacteria that were defined as core bacteria and putatively functionally important. In this study, using MiSeq sequencing technology, the core bacterial community of 98 operational taxonomic units (OTUs) was determined in a two-stage upflow blanket filter reactor treating pharmaceutical wastewater. The core bacterial community accounted for 61.66% of the total sequences and accurately predicted the sample location in the principal coordinates analysis scatter plot as the total bacterial OTUs did. The core bacterial community in the first-stage (FS) and second-stage (SS) reactors were generally distinct, in that the FS core bacterial community was indicated to be more related to a higher-level fermentation process, and the SS core bacterial community contained more microbes in syntrophic cooperation with methanogens. Moreover, the different responses of the FS and SS core bacterial communities to the temperature shock and influent disturbance caused by solid contamination were fully investigated. Co-occurring analysis at the Order level implied that Bacteroidales, Selenomonadales, Anaerolineales, Syneristales, and Thermotogales might play key roles in anaerobic digestion due to their high abundance and tight correlation with other microbes. These findings advance our knowledge about the core bacterial community and its temporal variability for future comparative research and improvement of the two-stage anaerobic system operation.

Microbial community shifts, associated with performance data, were investigated in an anaerobic batch digester treating high-solid food waste under mesophilic conditions using, a combination of molecular techniques and chemical analysis methods. The batch process was successfully operated with an organic removal efficiency of 44.5% associated with a biogas yield of 0.82 L/g $VS_{removal}$. Microbial community structures were examined by denaturing gel gradient electrophoresis. Clostridium and Symbiobacterium organisms were suggested to be mainly responsible for the organic matter catabolism in hydrolysis and acidogenesis reactions. The dynamics of archaeal and methanogenic populations were monitored using real-time PCR targeting 16S rRNA genes. Methanosarcina was the predominant methanogen, suggesting that the methanogenesis took place mainly via an aceticlastic pathway. Hydrogenotrophic methanogens were also supported in high-solid anaerobic digestion of food waste through syntrophism with syntrophic bacterium. Microbial community shifts showed good agreement with the performance parameters in anaerobic digestion, implying the possibility of diagnosing a high-solid anaerobic digestion process by monitoring microbial community shifts. On the other hand, the batch results could be relevant to the start-up period of a continuous system and could also provide useful information to set up a continuous operation.

Purpose: This study aimed to identify whether there is a difference between an online-based community psychiatric nursing practice program with the ARCS model and a conventional community psychiatric nursing practice program in promoting nursing students' learning motivation, knowledge of community psychiatric nursing, communication skills, and learning self-efficacy. Methods: This study used a quasi-experimental design with a non-equivalent control group. The participants were 44 nursing students at three nursing colleges in Gyeongsangbuk-do. The experimental group was provided the online-based community psychiatric nursing practice program with ARCS model, while the control group was provided the conventional community psychiatric nursing practice program from July 9, to September 3, 2022. Both groups received practice training 8 hours a day, 5 days two weeks. The collected data were analyzed using the exact χ², Mann-Whitney U-test, and Quade's two-way ANCOVA with the IBM SPSS Statistics 28.0 program. Results: The results of the comparison of an experimental group training with the online-based community psychiatric nursing practice program with ARCS model and a control group training with the conventional community psychiatric nursing practice program showed that, there was no statistically significant difference between the two groups in learning motivation knowledge of community psychiatric nursing, and learning self-efficacy. However, communication skills were statistically significantly higher in the experimental group (F=6.23, p=.017). Conclusion: The online-based community psychiatric nursing practice program with ARCS model can be used as a substitute learning to improve community psychiatric nursing capabilities in situations when clinical practice is suspended due to infectious diseases such as coronavirus disease 2019 or when is a shortage of community psychiatric nursing practice institutions.

The prevalence of non-communicable disease (NCD) has been continuously increasing due to population ageing, and the change in consumption and lifestyle patterns. Cancers, cerebrovascular diseases, and hypertensive diseases have been the major causes of deaths in the Republic of Korea since 1983. Numerous studies have suggested the need for a sustained comprehensive treatment tailored for individual patients and recommend the development of a systematic program to manage NCD patients to provide such care. It's necessary to develop the Korean model of the community based NCD prevention and control, consisting strategy of community movement, education for the NCD patients, and partnership the primary care clinic with public health organization to meet the needs in community people.

Objectives: This study aimed to identify and assess the factors related to the awareness, treatment, and control of hypertension based on jurisdictional areas of primary health care posts in a rural community of Korea. Methods: This study was performed on 4598 adults aged over 30 years in a rural community and we measured their blood pressure (BP) from October. 2007 to August. 2009. Hypertension is defined as a condition characterized by a systolic BP ${\geq}$ 140 mmHg, a diastolic BP ${\geq}$ 90 mmHg or reported treatment with antihypertensive medications. We analyzed the factors related with the prevalence, awareness, treatment and control of hypertension using chi-square test and multivariate logistic regression analysis. Results: The age-adjusted prevalence of hypertension was 34.7%. The age-adjusted rates of hypertension awareness, treatment and control were 50.6%, 93.9% and 64.1%, respectively. Awareness of hypertension was related with increasing age. Higher awareness was found among men who were felt more stress, were obese and had hypercholesterolemia, and among women who were regulary taking medicine for hypertension, were obese and had diabetes mellitus. In women, the hypertension treatment was related a Medical aid and education for hypertension management. Controlled hypertension was more common among men who were educated about the management of hypertension and among women who had hypercholesterolemia. Conclusions: The awareness of hypertension was low and the control of hypertension was high compared with the nationwide data (KNHANES 2005). The results suggest that understanding the characteristics of hypertension in a community is important to perform a community based hypertension control program.
