  • Purpose: The purpose of this study was to determine the effect of the Tai Chi exercise program (Sun style 31 forms) on fatigue, anxiety, and sleep patterns in nursing students. Methods: A quasi-experimental study with a non-equivalent control group pretest-posttest design was used. Nursing students who participated in this study were assigned to an experimental group (n=24), and a control group (n=26). The experimental group participated in Tai Chi exercise program for 60 minutes per session, and 3 times a week for 7 weeks. The Tai Chi exercise program consisted of 10 minutes for warm-up, 45 minutes for main session, and 5 minutes for cooling down exercises. The data were collected prior and after the intervention using self-administered questionnaires. Data were analyzed using descriptive statistics, $x^2$-test, Fisher's exact probability, t -test, and the general linear model. Results: After the application of the program, the experimental group showed a significant difference in fatigue (F=20.62, p<.001), anxiety (F=16.96, p<.001), and sleep pattern (F=15.70, p<.001) scores. Conclusion: These findings show that the Tai Chi exercise program can be an effective nursing intervention to improve sleep pattern and to reduce fatigue and anxiety in nursing students.

  • The rebustness of one sample Chi-square test for multivariate normal mean vector is investigated when the multivariate normal population is mixed with another multivariate normal population with differing in the mean vector. Explicit expressions for the level of significance and power of the test are derived. Some numerical results indicate that the Chi-square test procedure is quite robust against slight mixtures of multivariate normal populations differing in location parameters.

  • The article reports the results of an investigation on the practice of providing digital scholarship services at Vietnam National University Ho Chi Minh City, Vietnam. This study is part of an ongoing research project entitled Developing a digital scholarship service framework for universities at Vietnam National University Ho Chi Minh City. It employed a qualitative research approach through in-depth interviews with 31 individuals who are university managers, library managers, lecturers, and postgraduate and undergraduate students from six member universities and Central Library of Vietnam National University Ho Chi Minh City. Research results show that some digital scholarship services have been provided at Vietnam National University Ho Chi Minh City. However, they have not been yet systematically implemented and have not met users' needs. Lack of needed resources such as space, technology infrastructure, human resources, finance, and stakeholder support are among major challenges in developing digital scholarship services. The management of existing digital scholarship services is fragmented without a clear policy for developing digital scholarship and supporting services. The study contributes to the existing knowledge by adding substantially to current understanding of the practice of providing digital scholarship services in Vietnam's universities in the transition period, from state control to autonomy, which has not been much addressed in previous research. Furthermore, this study can be a useful reference for higher education institutions in developing countries regarding implementation of digital scholarship services.

  • Let $k$ be a real abelian field and $k_{\infty}$ be its $\mathbb{Z}_p$-extension for an odd prime $p$. Let $A_n$ be the Sylow $p$-subgroup of the ideal class group of $k_n$, the $nth$ layer of the $\mathbb{Z}_p$-extension. By using the main conjecture of Iwasawa theory, we have the following: If $p$ does not divide $\prod_{{{\chi}{\in}\hat{\Delta}_k},{\chi}{\neq}1}B_{1,{\chi}{\omega}^{-1}$, then $A_n$ = {0} for all $n{\geq}0$, where ${\Delta}_k=Gal(k/\mathbb{Q})$ and ${\omega}$ is the Teichm$\ddot{u}$ller character for $p$. The converse of this statement does not hold in general. However, we have the following when $k$ is of prime conductor $q$: Let $q$ be an odd prime different from $p$. and let $k$ be a real subfield of $\mathbb{Q}({\zeta}_q)$. If $p{\mid}{\prod}_{{\chi}{\in}\hat{\Delta}_{k,p},{\chi}{\neq}1}B_{1,{\chi}{\omega}}-1$, then $A_n{\neq}\{0\}$ for all $n{\geq}1$, where ${\Delta}_{k,p}$ is the $Gal(k_{(p)}/\mathbb{Q})$ and $k_{(p)}$ is the decomposition field of $k$ for $p$.

  • Purpose: The purpose of this study was to examine the effect of the Tai chi exercise program on the physical function, self-esteem and social behavior in patients with chronic schizophrenia. Methods: This study utilized a nonequivalent control group with pretest-posttest design. The 45 subjects were recruited from a mental health care facility in D city and randomly assigned either to the experimental group (n=23) or to the control group (n=22). The experimental group participated in the Tai chi exercise program, twice a week for 12 weeks. Data were analyzed with SPSSWIN V. 11.5 program, using $X^2$-test and t-test. Results: After 12 weeks, there were significant differences in flexibility (p=.027), balance (p=.011), self-esteem (p=.005) and social behavior (p=.003) between the experimental and the control groups. Conclusion: The findings of this study revealed the positive effects of Tai-Chi exercise program in patients with schizophrenia. Further studies are required to determine the effects on physical and social variables.

  • 열역학적 가정을 토대로 평형방정식을 이용하여 지반의 침투와 흙의 거동을 지배하는 불포화토 유한요소해석을 위한 수학적인 알고리즘을 개발하고, 여러 가지 유효응력 개념들을 수치해석을 통해 비교 분석하였다. 불포화토의 유효응력은 지반의 강도를 나타내며 지반이 함유하고 있는 수분과 모관흡수력의 중요한 구성관계를 표현한다. 특히, 불포화 지반내에서 물의 침투가 흙의 알갱이 거동을 예측하기 위해 여러 문헌에서 제안하고 있는 유효응력계수 ${\chi}$의 특성을 지반의 잔류포화도와 변위에 관련된 구성방정식 조건을 이해하기 위해 분석하였다. 그 결과, 불포화토 유효응력계수 ${\chi}$는 외부하중과 침투가 있는 지반내에서 모관흡수력의 분포를 변화시키지만, 지반의 잔류포화도에 따라 유효응력계수의 차이점을 보이며, 외부하중에 의한 지반 변위가 작아지면 유효응력계수 ${\chi}$는 지반내의 모관흡수력에 대한 영향력이 작아진다는 것을 확인할 수 있었다.
