Purpose: The purpose of this study was to describe and understand elementary school health teachers' role perception in their own perspectives. Methods: Data were collected from three focus groups composed of five participants for each group. Each focus group had an interview for two and a half hours on the average. The main question was "What is your perception on the roles of health teachers in elementary schools?" Qualitative data from transcribed notes and field notes were analyzed using qualitative content analysis. Results: Five main roles were identified from the participants. The participants perceived themselves as 'an expert of health education in school and community', 'a health service provider for school members', 'a health guardian for school members, the coordinator of healthcare related works in school, and the leader of school health. Conclusion: The participants have multiple role identities, which are very important for health management of school members. And the roles such as an expert of health education and a leader for school health are recently emphasized. The findings of this study can provide useful information to design orientation programs for newly appointed health teachers and continuing education programs for enhancing role performance of health teachers in elementary schools.

In the theory of hypergeometric functions of one or several variables, a remarkable amount of mathematicians's concern has been given to develop their transformation formulas and summation identities. Here we aim at presenting explicit expressions (in a single form) of the following weighted Appell's function $F_1$: $$(1+2x)^{-a}(1+2z)^{-b}F_1\;\(c,\;a,\;b;\;2c+j;\;\frac{4x}{1+2x},\;\frac{4z}{1+2z}\)\;(j=0,\;{\pm}1,\;{\ldots},\;{\pm}5)$$ in terms of Exton's triple hypergeometric $X_9$. The results are derived with the help of generalizations of Kummer's second theorem very recently provided by Kim et al. A large number of very interesting special cases including Exton's result are also given.

Virus-like symptoms including stunt, severe mosaic with malformation of leaves, fern-like leaves and abnormal petals were observed from an African impatiens (Impatiens walleriana) grown in a plant nursery in Icheon, Korea. Serological analysis using immuno-strip kits for viruses reported in African impatiens indicated that Cucumber mosaic virus (named CMV-Im) was a causal agent for the symptomatic African impatiens. Biological properties of CMV-Im were analyzed using responses of host plant species, suggesting that CMV-Im is a typical strain that belongs to CMV subgroup I. RT-PCR analysis verified CMV-Im infection from naturally infected African impatiens or mechanically inoculated some host species. Analysis of multiple alignments of CMV capsid protein (CP) sequences showed that CMV-Im shared high CP amino acids identities with other CMV strains. Phylogenetic tree analysis for the CP sequences of CMV-Im and representative CMV strains confirmed that CMV is a typical member of CMV subgroup I. To our knowledge, it is the first report of CMV in African impatiens in Korea.

An ID-based DNF signature scheme is an ID-based signature scheme with an access structure which is expressed as a disjunctive normal form (DNF) with literals of signer identities. ID-based DNF signature schemes are useful to achieve not only signer-privacy but also a multi-user access control. In this paper, we formally define a notion of a (non-interactive) ID-based DNF signature and propose the first noninteractive ID-based DNF signature schemes that are secure under the computational Diffie-Hellman and subgroup decision assumptions. Our first scheme uses random oracles, and our second one is designed without random oracles. To construct the second one, we use a novel technique that converts a non-interactive witness indistinguishable proof system of encryption of one bit into a corresponding proof system of encryption of a bit-string. This technique may be of independent interest. The second scheme straightforwardly yields the first ID-based ring signature that achieves anonymity against full key exposure without random oracles. We finally present two extensions of the proposed ID-based DNF signature schemes to support multiple KGCs and different messages.

Recently a cDNA clone of apoLp-III from Hyphantria cunea was isolated and subjected to computational analysis to compare with other available sequences. Multiple sequence alignments were carried out using the amino acid sequences of apoLp-III from six insects. It was found that the H. cunea apoLp-III has relatively high sequence identities to Spodoptera litura ($69.5\%$), Manduca sexta ($66.8\%$), Galleria mellonella ($65.1\%$), Bombyx mori N4 ($54.3\%$) but less identity to Locusta migratoria ($18.3\%$). The amino acid composition was compared with other insects using EXPASY tools; it shows that alanine (Ala), glutamine (Gln), leucine (Leu) and lysine (Lys) are the major amino acid components of apoLp-III in H. cunea as well as other lepidopterans. Homology modeling performed using PSI-BLAST (PDB template M. sexta) reveals that the apoLp-III molecules consist of five, long amphipathic alpha helical bundles with short loops connecting the helices and shows homology with other insects. Phylogenetic analysis shows that the orthopteran apoLp-III represented by locust was most distantly related to the lepidopteran insects.

Purpose : This descriptive research study aimed to identify the factors influencing nursing students' empathy and gender role identity and their effect on communication competence. Methods : Participants were 183 senior nursing students who had completed a clinical practice and simulation-based practical training course. Using the IBM SPSS/WIN 21.0 program, general characteristics were analyzed using descriptive statistics, independent variables were compared with t-tests and 𝑥² tests, and influencing factors on each variable and communication underwent multiple linear regression analysis. Results : Communication competence showed significant correlations with empathy (r=.40, p<.001), gender role identity (r=.53, p<.001), major satisfaction (r=.18, p=.013), and peer relationships (r=.24, p<.001). When gender was entered as a covariate, empathy (t=4.41, p<.001) and gender role identity (t=6.97, p<.001) were identified as predictors affecting communication competence with 36% explanation power (R²=.36, p<.001). Conclusion : The findings of this study suggest that course subjects considering the gender identities of students should be developed through various programs to establish students' identity as nurses and improve their empathy and communication.

Purpose - In this study, previous CSR researches was reviewed to help understand the CSR effects, and offer suggestions for future research directions. Research design, data, and methodology - To achieve the purpose of this study, previous CSR effects related researches were reviewed based on stakeholder perspectives. Results - After reviewing, some limitations were found. First, most of the CSR related studies in the management area have focused on CSR effects on individual stakeholders such as the shareholder, the employee, and the consumer. Second, it was difficult to find studies on the management aspect of CSR from both an effective and efficient perspective. Conclusions - To overcome these limitations of previous studies, several studies need to be conducted in the future. First, CSR research must be expanded into B-to-B businesses. Few studies try to figure out the effect of CSR on B-to-B businesses but only suggest the effect of CSR on B-to-B business conceptually. Therefore, empirical study needs to be conducted about CSR to show business performance in the B-to-B market. Second, the process of CSR must be developed on how to improve CSRs' effectiveness and efficiency. Finally, a relationship between a company and individual stakeholders needs to be revised using stakeholders' multiple identities.

This study examines factors influencing the corporate identity (CI) of pharmacy retail stores (PRSs) in Thailand as a means to construct a unique corporate identity to represent their strengths and image abroad. An exploratory sequential design was applied. A pilot study involving interviews with four pharmacists was conducted to obtain the variables, and then a questionnaire was designed and administered to 392 respondents. The collected data was analyzed to examine correlations via descriptive analysis, Pearson's correlation, and multiple linear regression (MLR). The results show that wisdom and pharmaceutical care explain 44% of the variance in defining Thai PRSs identity. There is a 61% chance that Thai PRSs should consider wisdom as the most important factor. These findings provide useful insights for pharmacists, pharmaceutical entrepreneurs, and owners of PRSs to enhance competitiveness by devising strategies to create their corporate identity. For the qualitative analysis, Thai PRSs should encourage pharmacists to gain real working experience to develop their wisdom, experience, and skills. Besides, PRSs that build identities as knowledgeable, sincere, and compassionate health providers can successfully expand their operations to other ASEAN countries, as end-consumers will be confident in the reliability of their services.

Globalization has diversified ethnic composition thus increased the risk of conflicts and socio-political instability in global cities. However, still the status of community facility in a global city is unclear despite its critical role to build sustainable community in global era. In Seoul, as a reaction of globalization, 19 community facilities known as the 'Seoul Global Center' have been established since 2007 by Seoul Metropolitan Government. These facilities have started to provide basic foreigner services but been transformed to foreigner service hub with multiple functions in terms of a living, a business, a labour, etc. This study explores the role of the community facility for foreigners by using the Seoul Global Center as a case study, conducting a site observation, an interview(13 staff) and a questionnaire(148 visitors). The findings are the community facility functions as a 'global platform' in forms of a policy tool for implementing the urban globalization strategy, a mediator connecting foreign migrants with local communities, an applicant for successful settlement of foreign residents, an incubator that grows human and social capital, and a base for collecting and aggregating information on foreign migrants and forming new local identities.

Motivated by several generalizations of the Pochhammer symbol and their associated families of hypergeometric functions and hypergeometric polynomials, by choosing to use a very generalized Pochhammer symbol, we aim to introduce certain extensions of the generalized Lauricella function F⁽ⁿ⁾_A and the Humbert's confluent hypergeometric function Ψ⁽ⁿ⁾ of n variables with, as their respective particular cases, the second Appell hypergeometric function F₂ and the generalized Humbert's confluent hypergeometric functions Ψ₂ and investigate their several properties including, for example, various integral representations, finite summation formulas with an s-fold sum and integral representations involving the Laguerre polynomials, the incomplete gamma functions, and the Bessel and modified Bessel functions. Also, pertinent links between the major identities discussed in this article and different (existing or novel) findings are revealed.
