  • The physicochemical properties and sensory characteristics of loins from crossbred Jeju black pigs from 4 different farms (Jl, J2, J3 and J4) were investigated. The approximate composition of loins were as follows; moisture 73.26∼74.75%, crude protein 22.78∼23.85%, crude fat 0.85∼1.81% and ash 1.23∼1.35%. The unsaturated fatty acid (60.21∼62.33%), pH (5.57∼5.70), water holding capacity (64.22∼69.40%), cooking loss (28.27∼30.45%), Hunter's L＊ (53.02∼55.64), a＊ (8.71∼9.87) and b＊ value (6.95∼7.29) of loins were not significantly different along the 4 samples (p>0.05). The crude fat contents and total amino acid (21.29%) of loin from farm J2 were higher than those from the others, and the hardness and chewiness were lower compared to those from farm Jl (p<0.05). The loin from farm J2 had a good score in sensory characteristics with regard to the taste (5.22), aroma (4.80), tenderness (5.30), juiciness (5.09) and palatability (5.33) of loins evaluated by the 7-point hedonic scale.

  • A signed 3-partite graph is a 3-partite graph in which each edge is assigned a positive or a negative sign. Let G(U, V, W) be a signed 3-partite graph with $U\;=\;\{u_1,\;u_2,\;{\cdots},\;u_p\},\;V\;=\;\{v_1,\;v_2,\;{\cdots},\;v_q\}\;and\;W\;=\;\{w_1,\;w_2,\;{\cdots},\;w_r\}$. Then, signed degree of $u_i(v_j\;and\;w_k)$ is $sdeg(u_i)\;=\;d_i\;=\;d^+_i\;-\;d^-_i,\;1\;{\leq}\;i\;{\leq}\;p\;(sdeg(v_j)\;=\;e_j\;=\;e^+_j\;-\;e^-_j,\;1\;{\leq}\;j\;{\leq}q$ and $sdeg(w_k)\;=\;f_k\;=\;f^+_k\;-\;f^-_k,\;1\;{\leq}\;k\;{\leq}\;r)$ where $d^+_i(e^+_j\;and\;f^+_k)$ is the number of positive edges incident with $u_i(v_j\;and\;w_k)$ and $d^-_i(e^-_j\;and\;f^-_k)$ is the number of negative edges incident with $u_i(v_j\;and\;w_k)$. The sequences ${\alpha}\;=\;[d_1,\;d_2,\;{\cdots},\;d_p],\;{\beta}\;=\;[e_1,\;e_2,\;{\cdots},\;e_q]$ and ${\gamma}\;=\;[f_1,\;f_2,\;{\cdots},\;f_r]$ are called the signed degree sequences of G(U, V, W). In this paper, we characterize the signed degree sequences of signed 3-partite graphs.

  • Electrical properties of Pd/Zn/Pd/Au contacts to p-InP were investigated as function of the V/III ratio of p-InP. P-type InP was made by the Zn diffusion into InP and activation process with rapid thermal annealing (RTA) measurement. After activation, the hole concentration was two orders of magnitude higher than that of the sample having only diffusion process. According to transmission line method (TLM) results, the specific contact resistance of p-InP was lower as used InP having the lower V/III ratio. The experimental results represent that the diffusion of Zn in undoped InP deeply related to the equilibrium between interstitials and substitutional Zn is established via indium interstitials.

  • Let P be a finite point set in ℝ2 with the set of distance n-chains defined as ∆n(P) = {(|p1 - p2|, |p2 - p3|, …, |pn - pn+1|) : pi ∈ P}. We show that for 2 ⩽ n = O|P|(1) we have ${\mid}{\Delta}_n(P){\mid}{\gtrsim}{\frac{{\mid}P{\mid}^n}{{\log}^{\frac{13}{2}(n-1)}{\mid}P{\mid}}}$. Our argument uses the energy construction of Elekes and a general version of Rudnev's rich-line bound implicit in [28], which allows one to iterate efficiently on intersecting nested subsets of Guth-Katz lines. Let G is a simple connected graph on m = O(1) vertices with m ⩾ 2. Define the graph-distance set ∆G(P) as ∆G(P) = {(|pi - pj|){i,j}∈E(G) : pi, pj ∈ P}. Combining with results of Guth and Katz [17] and Rudnev [28] with the above, if G has a Hamiltonian path we have ${\mid}{\Delta}_G(P){\mid}{\gtrsim}{\frac{{\mid}P{\mid}^{m-1}}{\text{polylog}{\mid}P{\mid}}}$.
