  • The purpose of this study is to analyze the difference of scalp and hair care behaviors according to DiSC behaviors of beauty consumer. For the study, 251 questionnaires were analyzed using the SPSS v.18.0 statistical package program. First, there was statistically significant difference in psychological stability, favorable image, and maintaining state of scalp and hair management according to DiSC behavior type. In case of Shin Jung - hyung (C), psychological stability, Positive images, and maintaining good condition. Second, DiSC and hair management behaviors according to DiSC behaviors showed statistically significant difference in state cognition management and product use management. In the case of cognition type (C) and social type (I) Product use management. The results of this study suggest that hair management awareness and behavior, which is dependent on DiSC behaviors of consumers, are provided as basic data for corporate marketing strategy.

  • The present paper consists of two parts. Since the recent paper [4] proved that an Alexandroff $T_0$-space is a semi-$T_{\frac{1}{2}}$-space, the first part studies semi-open and semi-closed structures of the Khalimsky nD space. The second one focuses on the study of a relation between the LS-property of ($SC^{n_1,l_1}_{k_1}{\times}SC^{n_2,l_2}_{k_2}$, k) relative to the simple closed $k_i$-curves $SC^{n_i,l_i}_{k_i}$, $i{\in}\{1,2\}$ and its normal k-adjacency. In addition, the present paper points out that the main theorems of Boxer and Karaca's paper [3] such as Theorems 4.4 and 4.7 of [3] cannot be new assertions. Indeed, instead they should be attributed to Theorems 4.3 and 4.5, and Example 4.6 of [10].

  • We cultured the rabbit inner medullary collecting duct (IMCD) cells as monolayers on collagen-coated membrane filters, and investigated distribution of the P2Y receptors by analyzing nucleotide-induced short circuit current $(I_{sc})$ responses. Exposure to different nucleotides of either the apical or basolateral surface of cell monolayers stimulated $I_{sc}.$ Dose-response relationship and cross-desensitization studies suggested that at least 3 distinct P2Y receptors are expressed asymmetrically on the apical and basolateral membranes. A $P2Y_2-like$ receptor, which responds to UTP and ATP, is expressed on both the apical and basolateral membranes. In addition, a uracil nucleotide receptor, which responds to UDP and UTP, but not ATP, is expressed predominantly on the apical membrane. In contrast, a $P2Y_1-like$ receptor, which responds to ADP and 2-methylthio-ATP, is expressed predominantly on the basolateral membrane. These nucleotides stimulated intracellular cAMP production with an asymmetrical profile, which was comparable to that in the stimulation of $I_{sc}.$ Our results suggest that the adenine and uracil nucleotides can interact with different P2Y nucleotide receptors that are expressed asymmetrically on the apical and basolateral membranes of the rabbit IMCD cells, and that both cAMP- and $Ca^{2+}-dependent$ signaling mechanisms underlie the stimulation of $I_{sc}$.

  • The susceptibility and control efficacy evaluated for 10 kinds of commercialized acaricides, to obtain basic data for the chemical control strategy of Two-spotted spider mite (Tetranychus urticae) in Hooker chives. The susceptibility evaluation of T. urticae female adults, Abamectin EC, Pyflubumide SC, Cyenopyrafen SC, and Acequinocyl SC showed 100% mortality, and Pyflubumide SC, Acequinocyl SC, and Etoxazole SC showed zero hatching rate, i.e. 100% mortality of eggs. As a result of evaluating the field test for Abamectin EC, Pyflubumide SC, Cyenopyrafen SC, Cyflumetofen SC, and Acequinocyl SC, which had excellent mortality in the laboratory conditions, all treatment plots showed more than 90.3% control efficiency on after 7 days.

  • The normal zone propagation (NZP) velocity and V-I characteristics of two Bi-2223 pancake coils with different Ag/SC ratio were investigated based on the experimental results and broad resistive transition were obesved in two coils. The measured NZP velocity of coil was found to be faster due to increase of Ag/SC ratio, and agree well with calculated data from two dimensional heat balance equation.

  • The normal zone propagation (NZP) velocity and V-I characteristics of two Bi-2223 pancake coils with different Ag/SC ratio were investigated by experiment. Non-uniformity of Ic and broad restive transition was oberserbed in two coils. The NZP velocity of azimuth direction is faster than radius direction, and the NZP velocity of coil with higher Ag/SC ratio is faster than another coil with lower Ag/SC ratio.

  • In this paper, we present a new lifetime prediction model for PMOSFET by using the correlation between transconductance degradation and substrate current influence. The suggested model is applied to a different channel structured PMOSFET, dgm/gm of both SC-PMOSFET and BC-PMOSFET appear with one straigth line about Qbib, therefore, this model is independent of channel structure. The suggested model is applied to a different drain structured SC-PMOSFET. Unlike S/D structured SC-PMOSFET, dgm/gm of LDD structured SC-PMOSFET appears with one straight line about Qb, therefore, this model is dependent of drain structure.

  • This paper offers performance analysis of selection decode and forward (DF) networks with differential modulation/demodulation for an arbitrary number of relays in independent but not identically distributed Rayleigh fading channels. We have shown that the selection DF protocol with differential modulation can achieve full diversity in both independent identically distributed (i.i.d.) and independent but not identically distributed (i.n.d.) Rayleigh fading channels, and the performance loss due to using non-coherent detection is not substantial. Furthermore, we study the impact of combining techniques on the performance of the system by comparing a system that uses selection combining (SC) to one that uses maximum ratio combining (MRC). Simulations are performed and show that they match exactly with analytic ones in high SNR regime.
