Purpoes: The study was done to investigate the effects of an exercise program on body composition, cardiopulmonary function and physical fitness in obese children. Methods: Thirty nine children in grades 4, 5, and 6 in elementary school were employed: experimental group(20) and control group(19). The subjects in the experimental group participated in an exercise program for 8weeks, thirty five minutes per session, four times per week. This data was analyzed by ANCOVA and paired t-test. Result: The Height(F=2.615, p=0.027) of the experimental group was significantly different from the control group. Also, in the experimental group, there were significant differences of height(t=4 79, p=0.000), cardiac rate(t=-6.461, p=0.000), body mass index(t=-2.13 p=0.046), muscle strength(t=3.48, p=0.003), and muscle endurance(t=3.20, p=0.005). Otherwise, in the control group, there were significant differences of weight(t=2.27, p=0.036), waist-hip ratio(t=3.16, p=0.005), and muscle endurance(t=-2.38, p=0.030). Conclusion: Jumping rope improved the body composition, cardiopulmonary function, and physical fitness for obese children.

Purpose: This study investigated the relationship of the partnership between nurses and parents of hospitalized children with the quality of pediatric nursing care as perceived by pediatric nurses. Methods: A cross-sectional descriptive study was conducted among 90 nurses. The data collected were analyzed using the independent t-test and the Pearson correlation coefficient. Results: The level of partnership between nurses and parents showed significant differences by nurses' age (t=2.22, p=.029) and marital status (t=2.54, p=.013). The quality of pediatric nursing care was found to significantly differ by the nurses' age (t=2.62, p=.013), marital status (t=4.17, p<.001), whether nurses had children (t=2.53, p=.020), pediatric ward work experience (t=2.43, p=.020), and total work experience (t=2.51, p=.016). The level of partnership between nurses and parents was positively correlated with the quality of pediatric nursing care (r=.48, p<.001). Conclusion: To improve the quality of nursing care for hospitalized children and their parents, it is important to consider the specific characteristics of pediatric nurses, whose clinical skills should be improved.

The purpose of this study was to find out the degree of satisfaction of body image and sex-role identity of primary school boys and girls and to examine their relevance between two sex groups. The data from study would be useful for mapping out some measures for school health education. Two hundred and forty five(245) students of 6th grade from 5 different primary schools in Seoul city and Gyonggi Province were selected for the study. The meaningful difference among demographic sociological characteristics between boys and girls has been shown to be in religion($x^2$=6.705, p=.044), the order of siblings($x^2$=7.455, p=.024), mother's academic career ($x^2$=6.705, p=.035) and the levels of living ($x^2$=4.108, p=.043). In the frequency distribution of sex-role identity, boys and girls were revealed as : undifferentiated 41.0%, 36.4%; as androgynous 24.8%, 25.8% respectively. Boys have masculinity (23.1%), on the other hand girls more feminity (22.7%). The meaningful difference of the degree of satisfaction of body image depends on father's ag(t=3.029, p=.050), mother's occupation(t=2.878, p=.023), home atmosphere(t=9.056, p=.000), level of livin(t=2.216, p=.028), academic achievements(t=4.580, p=.011). Masculine sex-role identity has shown its meaningful difference in mother's academic background(t=7.042, p=.001), academic achievements(t=14.963, p=.000). Feminine sex-role identity according to general characteristics shows meaningful difference in gender(t=2.683, p=.008), the order of siblings(t=3.019, p=0.51), father's academic career(t=5.558, p=.004) mother's academic background(t=7.676, p=.001), mother's occupation (t=3.405, p=.010), home atmosphere(t=4.492, p=.012), school performance(t=16.774, p=.000). Sex-role identity influences on the degree of satisfaction of body image as the relation bet ween the degree of satisfaction of body image and sex-role identity is pro correlative.

Let H be a separable complex H be a space and let (equation omitted)(H) be the *-algebra of all bounded linear operators on H. An operator T in (equation omitted)(H) is said to be p-hyponormal if ($T^{\ast}T)^p - (TT^{\ast})^{p}\geq$ 0 for 0 ＜ p ＜ 1. If p = 1, T is hyponormal and if p = $\frac{1}{2}$, T is semi-hyponormal. In this paper, by using a technique introduced by S. K. Berberian, we show that the approximate point spectrum $\sigma_{\alpha p}(T) of a pure p-hyponormal operator T is empty, and obtains the compact perturbation of T.

Let L be the subspace lattice generated by the subspaces $\{[e_1],[e_1,e_2],[e_1,e_2,e_3],{\cdots}\}$ and let $Alg{\mathcal{L}}$ be the algebra of bounded operators which leave invariant all projections in ${\mathcal{L}}$. Let p and q be natural numbers (p < q). Let ${\mathcal{A}}$ be a linear manifold in $Alg{\mathcal{L}}$ such that $T_{(p,q)}=0$ for all T in ${\mathcal{A}}$. If ${\mathcal{A}}$ is a Lie ideal, then $T_{(p,p)}=T_{(p+1,p+1)}={\cdots}=T_{(q,q)}$ and $T_{(i,j)}=0$, $p{\eqslantless}i{\eqslantless}q$ and i < $j{\eqslantless}q$ for all T in ${\mathcal{A}}$.

In this paper, we firstly use Krasnosel'skii fixed point theorem to investigate positive solutions for the following three-point boundary value problems for p-Laplacian with a parameter $({\phi}_P(D^{\alpha}_{0}+u(t)))^{\prime}+{\lambda}f(t, u(t))=0$, 0$D^{\alpha}_{0}+u(0)=u(0)=u{\prime}{\prime}(0)=0$, $u^{\prime}(1)={\gamma}u^{\prime}(\eta)$ where ϕ_p(s) = |s|^p−2s, p > 1, $D^{\alpha}_{0^+}$ is the Caputo's derivative, α ∈ (2, 3], η, γ ∈ (0, 1), λ > 0 is a parameter. Then we use Leggett-Williams fixed point theorem to study the existence of three positive solutions for the fractional boundary value problem $({\phi}_P(D^{\alpha}_{0}+u(t)))^{\prime}+f(t, u(t))=0$, 0$D^{\alpha}_{0}+u(0)=u(0)=u{\prime}{\prime}(0)=0$, $u^{\prime}(1)={\gamma}u^{\prime}(\eta)$ where ϕ_p(s) = |s|^p−2s, p > 1, $D^{\alpha}_{0^+}$ is the Caputo's derivative, α ∈ (2, 3], η, γ ∈ (0, 1).

다양한 식용식물에 함유되어 있는 것으로 알려진 phenolic acids의 일종인 p-coumaric acid의 항암활성을 규명하고자, 인체 급성백혈병 T 세포주인 Jurkat T 세포에 대한 p-coumaric acid의 에폽토시스 유도기전을 조사하였다. Jurkat T 세포를 p-coumaric acid (50-$150{\mu}M$)로 처리한 결과, 세포독성, 에폽토시스-관련 DNA fragmentation, 및 pro-apoptotic multidomain Bcl-2 family member인 Bak의 활성화, ${\Delta}{\psi}m$ loss, caspase-9, -3, -7, 및 -8의 활성화, 그리고 PARP 분해 등의 여러 에폽토시스-관련 생화학적 현상들이 농도의존적으로 나타났다. 그러나 이러한 에폽토시스-관련 생화학적 현상들은 Jurkat T 세포에 anti-apoptotic Bcl-2 단백질을 과발현할 경우에는 나타나지 않았다. 또한 p-coumaric acid처리에 의해 유도되는 Jurkat T 세포의 에폽토시스에는 necrosis가 수반되지 않는 것으로 확인되었다. Jurkat T 세포를 pan-caspase inhibitor인 z-VAD-fmk를 전처리할 경우, p-coumaric acid 처리에 의해 유도되는 apoptotic sub-$G_1$ peak는 차단되어 나타나지 않았으나 ${\Delta}{\psi}m$ loss는 여전히 나타났는데, 이는 p-coumaric acid처리에 의한 에폽토시스의 유도에 caspase cascade 활성화가 필수적이며 ${\Delta}{\psi}m$ loss의 downstream 현상임을 나타낸다. 한편, FADD 및 caspase-8을 함께 발현하는 Jurkat T 세포주 A3, FADD-결손 Jurkat T 세포주 I2.1, 그리고 caspase-8-결손 Jurkat T 세포주 I9.2의 p-coumaric acid의 세포독성에 대한 감수성은 서로 유사하게 나타났는데, 이는 p-coumaric acid처리에 의한 에폽토시스의 유도가 Fas와 FasL간의 상호작용에 의해 개시되지 않음을 시사한다. p-Coumaric acid의 세포독성은 Jurkat T 세포에 비해 인체 정상 말초혈액 T 세포에서 훨씬 낮게 나타났다. 이러한 결과들은 p-coumaric acid 처리에 의해 유도되는 Jurkat T 세포의 에폽토시스가 Bak 활성화, ${\Delta}{\psi}m$ loss, caspase-9, -3, -7, 및 -8로 이루어진 caspase cascade의 활성화, 그리고 PARP 분해에 의해 유도되며, 또한 anti-apoptotic 단백질인 Bcl-2의 과발현에 의해서 음성적으로 조절됨을 나타낸다.
