Purpose This study aims to identify the factors that form the social identity of metaverse community users and to investigate the processes that influence engagement behavior. Specifically, this study is to verify the structural relationship between socio-technical factors and social identity of metaverse community. Furthermore, we would figure out the role of psychological ownership and virtual assets in engagement of metaverse community members. Design/methodology/approach Hypotheses were derived through literature research and a survey was conducted for users of the metaverse community. 357 collected responses were analyzed for the structural equitation modeling(SEM) with AMOS 24.0. Findings As a result of the study, all of the proposed hypotheses were supported. As a result, it was found that technical and social perceptions of the metaverse community platform had a positive effect on social identity. Social identity affects the intention to engage in the metaverse community through psychological ownership, and its influence is reinforced by the perceived value of virtual assets.

Species identification in hydroacoustic survey is one of the key requirements to estimate biomass of organism and to understand the structure of zooplankton community. Feasibility of species identification using two frequencies (38 and 120 kHz) was investigated on the basis of mean volume backscattering strength difference (MVBS). Virtual echogram technique was applied to two frequencies data sets that obtained from surveys in the Antarctic Ocean and Yellow Sea. Virtual echogram method using MVBS revealed the possibility of species identification, which species identification relying on visual scrutiny of single frequency acoustic data resulted in significant errors in biomass estimation. Through noise cancellation using MVBS, much of the acoustic noise caused by acoustic instruments could be removed in new virtual echogram, and the biomass estimation and data quality was improved.

Hypertension has already become a serious health problem in many countries. Treatment is effective, however, and the detection and long-term management of those at risk pose sustained challenges. Community programs can be an important strategy for primary prevention of hypertention and for monitoring the progress and promoting compliance of hypertensive patients. Hwachon Health Demonstrain Project has designed community hypertention control program, especially emphasizing role of public health sector, and operate that model from 1990 at Hwachon county, Kwangwon province. This paper appraise the effectiveness of curent activities. Many paper appraise the effectiveness of curent activities. Many hypertensive persons who have not recognized his disease were identified and began hypertension treatment. However about two thirds of patients have not complied continuously with medical advice. Consequently, the project team redirects its efforts. Less emphasis is being placed screening and identification of patients, while more emphasis is being placed on increasing compliance with treatment recommendations. Some approches to improve hypertension control program are also discussed in the context of the field experience and literature on this suvjest.

The purpose of the study was to get some information about the educational program for consumers in the community. For this, the author investigated the ability to identify the imported foods and the educational contents to be taught. The subjects for this study were 183 housewives living in Cheongju city, and the research was conducted from March 1 to March 15, 2003. A survey questionnaire was distributed, asking general matters regarding the subject, attitude when purchasing foods, the ability to identify the imported foods, educational contents to be taught, and the identification ability between the domestic and the imported foods. The data was analyzed for percentage, mean, standard deviations using SAS program, and was also examined with Chi-square or ANOVA. $92.3\%$ of housewives checked the label to distinguish between the domestic food and the imported one, among which $99.5\%$ preferred to buy the domestic brand. For major reasons of this preference, $46.3\%$ of them reported that the imported foods had many harmful substances. $66.1\%$ of the subjects, however, replied that they did not have the ability to discern the differences between the two. The identification information was received from 'TV or radio program', which $61.7\%$ of the subjects reported as such. $61.5\%$ of the subjects were inclined to receive education about the imported foods. For the educational contents, $75.4\%$ wanted to learn 'the method to identify the imported foods'. According to the identification test on the imported foods, they got 13.6 points on the average out of 40 points, which was quite low. The highest correct answer was for pteridium aquilinum ($63.7\%$), sesame ($49.2\%$), and yellow croaker ($45.6\%$), while the highest incorrect answer was for red pepper powder ($40.4\%$), chestnut ($40.6\%$), and dried pepper ($32.2\%$). The results suggested that most of the respondents had negative attitudes towards the imported agricultural products, but their identification ability was quite poor. Therefore, it is necessary to provide education and publicity work in relation to the identification methods for the imported foods so that consumers may have less risk from the imported agricultural products.

BACKGROUND/OBJECTIVES: Accurate, early identification of acutely malnourished children has the potential to reduce related child morbidity and mortality. The current World Health Organisation (WHO) guidelines classify non-oedematous acute malnutrition among children under five using Mid-Upper Arm Circumference (MUAC) or Weight-for-Height Z-score (WHZ). However, there is ongoing debate regarding the use of current MUAC cut-offs. This study investigates the diagnostic performance of MUAC to identify children aged 6-24 months with global (GAM) or severe acute malnutrition (SAM). SUBJECTS/METHODS: Cross-sectional, secondary data from a community sample of children aged 6-24 months in Niger were used for this study. Children with complete weight, height and MUAC data and without clinical oedema were included. Using WHO guidelines for GAM (WHZ < -2, MUAC < 12.5 cm) and SAM (WHZ < -3, MUAC < 11.5 cm), the sensitivity (Se), specificity (Sp), predictive values, Youden Index and Receiver Operating Characteristic (ROC) curves were calculated for MUAC when compared with the WHZ reference criterion. RESULTS: Of 1161 children, 23.3% were diagnosed with GAM using WHZ, and 4.4% with SAM. Using current WHO cut-offs, the Se of MUAC to identify GAM was greater than for SAM (79 vs. 57%), yet the Sp was lower (84 vs. 97%). From inspection of the ROC curve and Youden Index, Se and Sp were maximised for MUAC < 12.5 cm to identify GAM (Se 79%, Sp 84%), and MUAC < 12.0 cm to identify SAM (Se 88%, Sp 81%). CONCLUSIONS: The current MUAC cut-off to identify GAM should continue to be used, but when screening for SAM, a higher cut-off could improve case identification. Community screening for SAM could use MUAC < 12.0 cm followed by appropriate treatment based on either MUAC < 11.5 cm or WHZ < -3, as in current practice. While the practicalities of implementation must be considered, the higher SAM MUAC cut-off would maximise early case-finding of high-risk acutely malnourished children.

Purpose: This study aims to verify whether avatars that embody different brand concepts offer different experiences to users. Furthermore, this study explores the relationship between user identification with avatars and their actual brand purchase intentions. Research design, data and methodology: The research design employed a between-subjects approach, with two independent variables: brand concept and avatar. The measured dependent variables were brand experience in extended reality (XR) and purchase intention. Additionally, brand attitude served as a control variable. Results: First, in virtual brand spaces with symbolic benefits, ideal avatars were found to elicit higher levels of brand experience than actual avatars. Specifically, participants reported elevated levels of entertainment and relational assembly experiences in symbolic brand spaces. Second, this research reveals that the relationship between users' identification with avatars and their intention to make actual brand purchases is mediated by brand experience in XR. Conclusions: The findings suggest that ideal avatars evoke higher levels of brand experience within symbolic brand spaces, particularly in entertainment, relational connection, and a sense of community. Furthermore, this study establishes the role of brand experience in XR as a mediator between avatar identification and purchase intentions.

Culture-independent approaches, based on 16S rDNA sequences, are extensively used in modern microbial ecology. Sequencing of the clone library generated from environmental DNA has advantages over fingerprint-based methods, such as denaturing gradient gel electrophoresis, as it provides precise identification and quantification of the phylotypes present in samples. However, to date, no method exists for comparing multiple bacterial community structures using clone library sequences. In this study, an automated method to achieve this has been developed, by applying pair wise alignment, hierarchical clustering and principle component analysis. The method has been demonstrated to be successful in comparing samples from various environments. The program, named CommCluster, was written in JAVA, and is now freely available, at http://chunlab.snu.ac.kr/commcluster/.
