(1) The direct product (equation omitted) $E_{I}$ of BCK-algebras $E_{I}$, (i=1, 2, 3, …, n), is a BCK-algebra. (2) Let E be a BCK-algebra and $A_1$, $A_1$, …, $A_{n}$ ideals of E. Define a mapping (equation omitted) by the rule f($\chi$)=( $A_1$$\chi$, $A_2$$\chi$, …, $A_{n}$$\chi$). Then f is a homomorphism.ism.ism.

Purpose: This study aims to conduct a systematic review of the physical, psychosocial and physiological effects of Tai Chi exercise in elderly. Method: 37 articles from Medline search of foreign journals (1966-2006) were surveyed by the key words 'Tai Chi', 'Tai-chi program' and 'Tai-chi and elderly' limiting the range to age 65 or older, choosing clinical trial and randomized controlled trial research in English articles. Four articles were excluded due to methodological study, pilot study and review. The research was analyzed according to health status of the subjects, styles and forms of Tai Chi exercises, factors for physical, psychosocial and physiological measures. Result: A short forming Yang style was commonly used in chronic diseases and health for elderly. Variable outcome measures were used in Tai Chi studies relating to balance, muscle strength, walking and mobility, flexibility and cardiorespiratory function in physical measure, quality of life, depression, self-efficacy, health status, cognition and impact questionnaire in psychosocial measure, lipids, insulin resistance and hormone in physiological measure. Conclusion: Tai Chi exercise appears to have physical and psychosocial benefits and also appears to be safe for elderly and chronic diseases. It is suggested that future studies analyze statistical part of systematic reviews through meta analysis.

Let $G{\leq}S_n$ and ${\chi}$ be any nonzero complex valued function on G. We first study the irreducibility of the generalized matrix polynomial $d^G_{\chi}(X)$, where $X=(x_{ij})$ is an n-by-n matrix whose entries are $n^2$ commuting independent indeterminates over $\mathbb{C}$. In particular, we show that if $\mathcal{X}$ is an irreducible character of G, then $d^G_{\chi}(X)$ is an irreducible polynomial, where either $G=S_n$ or $G=A_n$ and $n{\neq}2$. We then give a necessary and sufficient condition for the equality of two generalized matrix functions on the set of the so-called ${\chi}$-singular (${\chi}$-nonsingular) matrices.

For the evaluation algebra $F[e^{{\pm}{\chi}}]_M$, if M={$\partial$}, the automorphism group $Aut_{non}$($F[e^{{\pm}{\chi}}]_M$) and $Der_{non}$($F[e^{{\pm}{\chi}}]_M$) of the evaluation algebra $F[e^{{\pm}{\chi}}]_M$ are found in the paper [12]. For M={${\partial}^n$}, we find $Aut_{non}$($F[e^{{\pm}{\chi}}]_M$) and $Der_{non}$($F[e^{{\pm}{\chi}}]_M$) of the evaluation algebra $F[e^{{\pm}{\chi}}]_M$ in this paper. We show that a derivation of some non-associative algebra is not inner.

Objective : This study was conducted to offer basic materials for the clinical study of Chi acupuncture (carboxytherapy). Methods : Recent clinical studies were reviewed for carboxytherapy (carbon dioxide therapy) and the ancient and present texts were reviewed for Chi acupuncture. Results and Conclusions : Chi acupuncture is oriental medical therapeutic treatment using carboxytherapy. Chi acupuncture refers to the transcutaneous administration of CO2 gas for therapeutical purposes relating to obesity, cellulites, local circulation and skin irregularity. Recent studies have demonstrated the effects of this therapy on adipose tissue by showing vasomotor effects, increasing local circulation and inducing a partial increase in tcPO2. Chi acupuncture influences the microcirculation and likely has a positive effect upon the physiological oxidative lipolytic process.

Chlorophyll (Chi) d was assigned to an antenna pigment of red algae in 1943, but its presence and function in red algae have not been necessarily clear for a long time. In 1996, it was shown that Chi d functioned as a major antenna pigment in a peculiar oxygenic photosynthetic prokaryote, Acaryochloris marina, isolated as a symbiont of a colonial ascidian from coral reefs. This finding evoked the necessity for reexamination of the presence and function of Chi d in red algae. We found Chi d in methanol-extract from several marine red algae, and the relative content was high in one species, Ahnfeltiopsis flabelliformis. Absorption and fluorescence spectra, HPLC analysis, and NMR and mass spectroscopy characterized Chi d extracted from the red algal thalli, and those were essentially identical to those of Chi d isolated from A. marina. However, micro-spectrophotometric analysis suggested that Chi d was not an actual constituent of the red algae but came from epiphyte(s) attached to surface of red algal thalli.

Health literacy is the degree to which individuals have the capacity to obtain, process, and understand basic health information and services needed to make appropriate health decisions. Librarians should improve their health literacy as well as that of their users' in order to help library users make well-informed decisions. In this study, we developed educational programs related to CHI (Consumer Health Information) suitable for Korean public librarians' professional development. We measured the effectiveness of the training after its administration and found areas in which improvement was necessary. As a result, this study found the following effects on public librarians after they completed the training: improved the public librarians' familiarity with CHI-related terms; increased education for users and diversification of resources; diversification and specialization of information sources which librarians used to perform CHI-related services; reduced time for reference services; increased professional knowledge in this area. However, this research represented the first time CHI-related education for public librarians was performed in Korea, and therefore many limitations were present in the education instructor, the diversity of subjects, and the methodology. Development of more advanced CHI-related education programs is required.

Purpose: The purpose of this study was to explore the experiences of Tai Chi in women with osteoarthritis. Methods: Data were collected by face-to-face interview from 14 participants. Theoretical sampling was performed until the concepts were saturated. The main question was "How do you describe your experience of Tai Chi?" Data were analyzed using a grounded theory methodology. All interviews were audio taped and transcribed verbatim. Results: The Phenomenon is 'QI flowing'. The core category was identified with 'inspiring one's life with strength'. This series of processes was categorized into four stages: 'Challenging Tai chi', 'Doing one's best', 'Deplenishing (the word used in English and Tai chi is emptying one's mind) one's mind', 'Taking a Positive view of life'. Conclusion: The finding of this study will offer profound understanding about the reported tai chi's experience. Additional research should be done as to the role of Tai chi as a nursing intervention strategy for osteoarthritis patients.

The study investigates Environmental Accounting Information (EAI) as well as factors affecting the environmental accounting implementation by the construction firms listed on the Ho Chi Minh Stock Exchange (HOSE), Vietnam. After eliminating seven enterprises that lacked data, the authors selected a sample of 112 observations from 28 construction businesses listed on the Ho Chi Minh Stock Exchange in the period 2015-2018. This study uses research data extracted from the companies' annual reports. Then, the data are analyzed by Stata 13 software, including descriptive statistics, correlation coefficient analysis, regression analysis of table data using estimation methods (Pooled OLS, REM, FEM), and testing of model defects (heteroskedasticity test, multicollinearity test, autocorrelation test). The results show that construction companies listed on the Ho Chi Minh Stock Exchange have out factors affecting the environmental accounting implementation by these enterprises, including independent audit firm and listed time. While the independent auditor firm has a positive and significant impact, the listed time has a negative influence. In addition, our study has confirmed the role of institutional factors affecting the disclosure level of EAI on the implementation of environmental accounting by construction enterprises listed on the Ho Chi Minh Stock Exchange.
