Comparative blook analysis was carried out to investigate the difference of blood constituent in four types of physical constitution. Isoleucine(Ile), Alanine(Ala), Cysteine(Cys), Tyrosine(Tyr), Methionine(Met) were measured. And the following results were obtained: 1. The value of Isoleucine(Ile) on the constitution didn't shown significant difference, but between the value of SO-YANG-IN and SO-EUM-IN showed significant difference. 2. The value of Alanine(Ala) on the constitution didn't shown significant difference. 3. The value of Cysteine(Cys) on the constitution didn't shown significant difference, but between the value of SO-YANG-IN and SO-EUM-IN showed significant difference. 4. Between the value of control group and SO-YANG-IN showed significant difference, and between the value of SO-YANG-IN and TAE-EUM-IN, SO-YANG-IN and SO-EUM-IN showed significant difference. 5. Between the value of control group and SO-YANG-IN showed significant difference.

Recently, a new kind of multiple zeta value of level two T(k) (which is called multiple T-value) was introduced and studied by Kaneko and Tsumura. In this paper, we define a kind of alternating version of multiple T-values, and study several duality formulas of weighted sum formulas about alternating multiple T-values by using the methods of iterated integral representations and series representations. Some special values of alternating multiple T-values can also be obtained.

This study was conducted to investigate the physicochemical quality characteristics of pork patty added with four different amount (T0:0%, T1:0.3%, T2:0.7%, T3:1.0%) of tangerine (Citrus unshiu) peel. There was no significant difference in chemical composition, cooking yield, water holding capacity, moisture retention, fat retention, hardness, springiness, cohesiveness, gumminess, chewiness, VBN content, L-value. In taste, texture, juiciness and palatability, the addition of 0.3%~1.0% tangerine peel in pork patty showed no significant difference on sensory properties compared to the pork patty without tangerine peel. Total polyphenol content was highest in T3, and DPPH radical scavenging activity was highest in T2 and T3 (p<0.001). The TBARS contents decreased as tangerine peel become added (p<0.001). The pH was highest in T0, and was lowest in T3 (p<0.001). The external a-value of T2 and T3 were significantly higher than that of T0 (p<0.01). The external and internal b-value of T2 and T3 were higher than those of T0 (p<0.01). Flavor of T2 and T3 were higher than those of T0 and T1 (p<0.01). In conclusion, the results of this study indicate that an addition of tangerine peel could be utilized as an ingredient in pork patty in promotion of function of tangerine by-products.

The existence of solutions of the following multi-point boundary value problem $${x^{(n)}(t)=f(t,\;x(t),\;x'(t),{\cdots}, x^{(n-2)}(t))+r(t),\;0 is studied. Sufficient conditions for the existence of at least one solution of BVP(*) are established. It is of interest that the growth conditions imposed on f are allowed to be super-linear (the degrees of phases variables are allowed to be greater than 1 if it is a polynomial). The results are different from known ones since we don't apply the Green's functions of the corresponding problem and the method to obtain a priori bounds of solutions are different enough from known ones. Examples that can not be solved by known results are given to illustrate our theorems.

Comparative blood analysis was carried out to investigate the change of blood constituent in TAE-EUM-IN group and control group. RBC, WBC, hemoglobin, hematocrit, total protein, triglyceride, phospholipid, total cholesterol, LDL-cholesterol, HDL-cholesterol, BUN, creatinine, ACTH, cortisol and prostaglandin E and $F_2{\alpha}$ were measured. And the following results were obtained: 1. In the change of blood cell, the value of hematocrit showed significant difference, while that of RBC, WBC and himoglobin didn't. 2. In the change of protein, the value of total protein showed significant difference, but that of albumin didn't. 3. In the change of lipid and cholesterol in serum, the value of triglyceride, phospholipid, total cholesterol and LDL-cholesterol indicated significant difference, while that of HDL-cholesterol indicated significant difference, while that of HDL-cholesterol didn't. 4. The value of BUN in serum represented significant difference, but that of creatinine didn't. 5. The value of cortisol in plasma showed significant difference, but that of ACTH didn't. 6. The value of prostaglandin E and $F_2{\alpha}$ in plasma showed significant difference. These results suggest that investigation on hormones and blood constituents enables objectification in differentiation of four types of physical constitution.

This study was designed to find out the effects of country-of-origin and price on the perceived quality, perceived value and purchase willingness of t-shirt products. This study will allow marketers to find the target consumers and to choose both the suitable country -of -origin and the reasonable selling price. This study was based on theoretical and empirical methods. For the empirical methodology, 3${\times}$3 between subjects factorial design with country-of-origin (U.S.A. vs. Korea vs. China) and price(high price vs. middle price vs. low price) was used. The nine types surveys by country-of-origin and price were transmitted to 960 undergraduate and graduate school students in Seoul. A total of 912 questionnaires were used in the final statistical analyses using factor analysis, MANOVA, Duncan test, and Tukey test. The results of this study were as follows: First, in the case of the perceived quality, participants evaluated t-shirt products better when the origin is U.S.A. followed by Korea and China in the order. Second, price affected the perceived value and purchase willingness. In the perceived value and purchase willingness, low priced t-shirt products were evaluated higher than the middle and high priced ones. Third, in the perceived quality, high priced Korean t-shirt products were evaluated lower than high and middle priced American t-shin products. In the perceived value, low priced Chinese t-shirt products were evaluated lower than middle priced Korean t-shirt products. In the purchase willingness, low priced American and low priced Korean t-shirt products and middle priced Korean t-shirt products were evaluated higher than all priced Chinese t-shirt products.

This paper deals with the multipoint boundary value problem for one dimensional p-Laplacian $({\phi}_p(u'))'(t)$ + f(t,u(t)) = 0, $t{\in}$ (0, 1), subject to the boundary value conditions: u'(0) - $\sum\limits^n_{i=1}{\alpha_i}u({\xi}_i)$ = 0, u'(1) + $\sum\limits^n_{i=1}{\alpha_i}u({\eta}_i)$ = 0. Using a fixed point theorem for operators on a cone, we provide sufficient conditions for the existence of multiple (at least three) positive solutions to the above boundary value problem.

This paper is concerned with the following fourth-order four-point Sturm-Liouville boundary value problem $u^{(4)}(t)=f(t,\;u(t),\;u^{\prime\prime}(t))$, $0\;{\leq}\;t\;{\leq}1$, ${\alpha}u(0)-{\beta}u^{\prime}(0)={\gamma}u(1)+{\delta}u^{\prime}(1)=0$, $au^{\prime\prime}(\xi_1)-bu^{\prime\prime\prime}(\xi_1)=cu^{\prime\prime}(\xi_2)+du^{\prime\prime\prime}(\xi_2)=0$. Some sufficient conditions are obtained for the existence of at least one positive solution to the above boundary value problem by using the well-known Guo-Krasnoselskii fixed point theorem.

In this paper, we study the self-adjoint second order boundary value problem with integral boundary conditions: (p(t)x'(t))'+f(t,x(t))=0, t $${\in}$$ (0,1), x'(0)=0, x(1) = $${\int}_0^1$$ x(s)g(s)ds. A new result on the existence of positive solutions is obtained. The interesting points are: the first, we employ a new tool-the recent Leggett-Williams norm-type theorem for coincidences; the second, the boundary value problem is involved in integral condition; the third, the solutions obtained are positive.

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).
