This work is a continuation of our investigations for p-adic analogue of the alternating form Dirichlet L-functions $$L_E(s,{\chi})={\sum\limits_{n=1}^{\infty}}{\frac{(-1)^n{\chi}(n)}{n^s}},\;Re(s)>0$$. Let L_p,E(s, t; χ) be the p-adic Euler L-function of two variables. In this paper, for any α ∈ ℂ_p, |α|_p ≤ 1, we give a power series expansion of L_p,E(s, t; χ) in terms of the variable t. From this, we derive a power series expansion of the generalized Euler polynomials with negative index, that is, we prove that $$E_{-n,{\chi}}(t)={\sum\limits_{m=0}^{\infty}}\(\array{-n\\m}\)E_{-(m+n),{\chi}^{t^m}},\;n{\in}{\mathbb{N}}$$, where t ∈ ℂ_p with |t|_p < 1. Some further properties for L_p,E(s, t; χ) has also been shown.

Purpose: To suggest ideas that promote sexual health and useful in planning sex education programs for middle school students. Method: This study surveyed 661 middle school students from three schools in Seoul and Chunchon. Result: The average degree of sexual knowledge was 31.5, while attitude was 32.5. There were statistically significant differences in sexual knowledge in relation to: coeducational environment (t=-5.776, p=.000), grade (F=36.351, p=.000), father's age (t=-2.510, p=.012), mother's age (t=-2.146, p=.032), economical status (F=3.264, p=.039), source of sexual knowledge (F=8.484, p=.000), the degree of interest in the opposite sex (F=16.871, p=.000), sexual discussions with parents (t=3.556, p=.000), sexual discussions with teachers (t=2.847, p=.005), and sex education (t=2.148, p=.032). Likewise, stastically significant differences in sexual attitudes were linked to: coeducational environment (t=-7.646, p=.000), subject's grade (F=32.743, p=.000), parental marriage status (t=2.338, p=.020), mother's age (t=-2.048, p=.041), source of sexual knowledge (F=6.917, p=.000), the degree of interest in the opposite sex (F=15.559, p=.000), sexual discussions with parents (t=3.908, p=.000), and sexual discussions with teachers (t=2.946, p=.003). The students level of sexual knowledge and attitude was significantly correlated (r=.686, p=.000). Conclusion: This study indicates a variety of systematic sexual education programs are needed for middle school student at home and school.

Let $\mathbb{N}_0$ be the set of non-negative integers, and let P(n, l) denote the set of all weak compositions of n with l parts, i.e., $P(n,l)=\{(x_1,x_2,{\cdots},x_l){\in}\mathbb{N}^l_0\;:\;x_1+x_2+{\cdots}+x_l=n\}$. For any element $u=(u_1,u_2,{\cdots},u_l){\in}P(n,l)$, denote its ith-coordinate by u(i), i.e., $u(i)=u_i$. A family $A{\subseteq}P(n,l)$ is said to be t-intersecting if ${\mid}\{i:u(i)=v(i)\}{\mid}{\geq}t$ for all $u,v{\epsilon}A$. A family $A{\subseteq}P(n,l)$ is said to be trivially t-intersecting if there is a t-set T of $[l]=\{1,2,{\cdots},l\}$ and elements $y_s{\in}\mathbb{N}_0(s{\in}T)$ such that $A=\{u{\in}P(n,l):u(j)=yj\;for\;all\;j{\in}T\}$. We prove that given any positive integers l, t with $l{\geq}2t+3$, there exists a constant $n_0(l,t)$ depending only on l and t, such that for all $n{\geq}n_0(l,t)$, if $A{\subseteq}P(n,l)$ is non-trivially t-intersecting, then $${\mid}A{\mid}{\leq}(^{n+l-t-l}_{l-t-1})-(^{n-1}_{l-t-1})+t$$. Moreover, equality holds if and only if there is a t-set T of [l] such that $$A=\bigcup_{s{\in}[l]{\backslash}T}\;A_s{\cup}\{q_i:i{\in}T\}$$, where $$A_s=\{u{\in}P(n,l):u(j)=0\;for\;all\;j{\in}T\;and\;u(s)=0\}$$ and $$q_i{\in}P(n,l)\;with\;q_i(j)=0\;fo\;all\;j{\in}[l]{\backslash}\{i\}\;and\;q_i(i)=n$$.

Purpose: To examine the effects of a 36-week resistance training program on body composition, fitness and blood lipid profiles in the obese elderly. Method: fourteen subjects were assigned into the resistance training group. The 12-16 exercise sessions were performed for 60min with 15-25 repetitions twice per week for 36 weeks. Data were analyzed by paired t-test with SPSS version 12.0 for Windows. Results: Significant changes were evident in weight (t=5.983, p<.001), body mass index (t=5.922, p<.001), % body fat (t=3.480, p=.004), and fat free mass (t=-2.592, p=.022). Concerning exercises, no significance was noted for back scratch (t=-1.814, p=.093), but were for 2-min step (t=-3.075, p=.009), arm curl (t=-2.223, p=.045), chair stand (t=-3.671, p=.003), chair sit and reach (t=-2.508, p=.026), and 8-ft up and go (t=5.545, p<.001). No significant changes were evident in total cholesterol (t=1.189, p=.279), and total glucose (t=0.689, p=.517), while the change in high-density lipoprotein was significant (t=3.535, p=.012). Conclusion: The 36-week resistance training program enhanced body composition and physical fitness, but not blood lipid profiles in obese elderly subjects.

The Objectives of this research is to determine the effect of aerobic exercise program on health status and physical fitness in patients after the stem cell transplantation. This research design is one-group pretest-post test design. Sixteen subjects were selected from one university hospital in Seoul for the study, they was carried out aerobic exercise three to five times a week for 12 weeks. The period of data collection was from February to July, 2000. The collected data was analysed by descriptive analysis, paired t-test, content analysis SAS program was used for the statistical analysis. The results are as follows : 1. There was a significant improvement in the Physical functioning, Vitality and Reported change (t=2.39, p=0.03; t=2.35, p=0.03; t=2.58, p=0.02) but no change was observed in the Role physical, General health perception, Bodily pain, Social functioning, Role emotional and Mental health. 2. There was a significant improvement in the physical fitness (higher VO2 max, t=2.43, p=0.02; lower systolic pressure, t=-4.09, p=0.001; lower diastolic pressure, t=-3.43, p=0.002; lower pulse rate, t=-3.43, p=0.004; higher muscle sustaining power, t=2.79, p=0.015; higher muscle power, t=5.18 p=0.000; higher power of beginning, t=5.55, p=0.001; higher the sense of equilibrium, t=3.57, p=0.003; higher Hemoglobin, t=5.92, p=0.000; higher Hematocrit, t=5.38, p=0.000). Therefore, this study will provide a theoretical back ground for patients after stem cell transplantation to understand the importance of physical exercise and maintain physical exercise; and for other researches to refer to the results for exercise protocol of rehabilitation program.

Objectives: The purpose of this study was to examine effects of health promotion program based on self-efficacy theory on physiological indicators, self-efficacy, grits, and health promotion behavior in community elderly. Methods: A non-equivalent control group pre-post test design was used. The intervention group received the health promotion program based on self-efficacy theory for 8 weeks from October 8 to November 26, 2020. Results: t-test showed that systolic blood pressure (t=-2.12, p=.040), self-efficacy (t=3.78, p<.001), grit (t=3.75, p<.001) and health promotion behavior (t=2.89, p=.002) were significant differences between the two groups. In other hands BMI (t=-1.26, p=.213), diastolic pressure (t=-1.07, p=.287), total cholesterol (t=-1.67, p=.102), LDL-cholesterol (t=-0.76, p=.451), HDL-cholesterol (t=-0.57, p=.567) and triglyceride (t=-1.76, p=.094) were no significant difference between two groups. Conclusions: The health promotion program based on self-efficacy theory was found to be an effective nursing intervention program in improving physiological indicators, self-efficacy, grit and health promotion behaviors of community elderly.

For a positive integer k and a positive number 0 < p$\le$1, an operator T is said to be (p, k)-quasiposinormal if $T^{{\ast}k}(c^2(T^{\ast}T)P - (TT^{\ast})^P)T^k {\ge} 0$ for some c > o. In this paper we consider a structure for (p, k)-quasiposinormal.

본 연구는 연잎추출물의 첨가가 분쇄돈육의 냉장 중 이화학적 품질에 미치는 영향을 규명하고자 하였다. 분쇄돈육은 돈육 88%, 대두유 5%, 소금 2%, 냉수 5%를 배합하여 제조한 대조군(T0), 여기에 냉수대신 3% 연잎추출물을 첨가한 T1, 7% 연잎추출물을 첨가한 T2 그리고 10% 연잎추출물을 첨가한 T3 등 네 종류의 분쇄돈육을 제조하였다. 이들은 냉장 중 pH, TBARS, VBN 함량, 표면과 내부의 색깔, 보수력, 가열감량, 경도 및 씹힘성을 측정하였다. 분쇄돈육의 pH는 저장 중 높아지다가 10일째 유의하게 감소하였다(p<0.05). TBARS는 저장 중 유의하게 증가하여 저장 10일째 T0, T1, T2 및 T3가 각각 0.777, 0.244, 0.185 및 0.182 mg MA/kg을 나타내었다(p<0.05). VBN 함량은 저장 중 T0 및 T1은 유의하게 증가하였으나, T2 및 T3는 유의한 변화가 없었다. 표면 색깔의 경우, 명도($L^*$)는 저장 중 증가하였으며, T0가 가장 높았다(p<0.05). 적색도($a^*$)는 저장 중 감소하였으며, 황색도($b^*$)는 저장 초기가 가장 높았다(p<0.05). 내부 색깔의 경우, 명도는 저장 중 유의한 변화가 없었으나, 적색도는 유의하게 감소하였다(p<0.05). 그러나 황색도는 유의하게 증가하였다(p<0.05). 보수력은 저장 중 유의하게 증가하였으며, T2 및 T3가 가장 높았다(p<0.05). 가열감량은 저장 중 유의하게 감소하였으며, T0 및 T1이 T2 및 T3보다 유의하게 높았다(p<0.05). 경도 및 씹힘성은 저장 중 유의한 변화가 없었으며, 시료들 사이에도 차이가 없었다.
