The metabolism and pharmacokinetics of M-l, which is metabolite of pentoxifylline, have been studied in human liver microsomes. Biphasic kinetics was observed from the Eadie-Hofstee plot for the formation of both metabolites of M-l. For the kinetics of pentoxifylline, mean values of $V_{max1}{\;}and{\;}V_{max2}$ were 1,648 and 5,622 nmol/min/mg protein, and the estimated values of $K_{ml}{\;}and{\;}K_{m2}$ were 0.180 and 4.829 mM, respectively. For M-3, mean values of $V_{max1}{\;}and{\;}V_{max2}$ were 0.062 and 0.491 nmol/min/mg protein, and estimated values of $K_{ml}{\;}and{\;}K_{m2}$ were 0.025 and 1.216 mM. The formations of pentoxifylline and M-3 from M-1 were indentified by using several selective inhibitors of cytochrome P450 isoformes at 0.05-5 mM concentration of M-1 in human liver microsomes. For the analysis of low (0.05 mM) concentration of M-1, where the affinity was expected as low, indicated that CYPlA2 and CYP3A4 were major P450 isoforms responsible for pentoxifylline and M-3 formation. CYP3A4 and CYP2A6 appeared to be P450 isoforms responsible for M-3 formation at high (5 mM) concentration of M-1.

The purpose of this study is to investigate the effect of retail therapy (RT) values and the role of body consciousness on therapeutic shopping motivations and outcomes. In order to accomplish our research aim, we investigated therapeutic shopping values (i.e., positive mood reinforcement and negative mood reduction) and the moderating effects of body surveillance, body shame, and weight preoccupation. A total of 247 female college students in the United States participated in an online Qualtrics survey, and structural equation modeling (SEM) and multigroup analysis were performed to analyze the data. The findings reveal that therapeutic shopping values (positive mood reinforcement and negative mood reduction) significantly influence therapeutic shopping motivation. Therapeutic shopping motivation, in turn, positively influences therapeutic shopping outcomes. Moreover, weight preoccupation moderates the relationship between negative mood reduction and therapeutic shopping motivation, suggesting that RT should especially be utilized for weight-conscious individuals. The results can be utilized for retailers to develop marketing strategies for consumers who are conscious about their appearance. Academic and managerial implications, along with future research, are suggested.

The purpose of this study is to present the aesthetic values of the Korean traditional costume for developing 'Korean' fashion design can be accepted in general in the modern times. For this purpose, documentary studies about the aesthetic values of the Korean traditional art and Korean traditional costume were preceded. And the perception of the Korean traditional costume were studied according to Belong's two criteria, body priority/ clothes priority and open/closed. Next, the aesthetic values of the Korean traditional costume were re-defined. The results can be summarized as follows; 1) The aesthetic values of the Korean traditional art are the beauty of nature, the purity, and the pleasantry. As the beauty of nature is the important one, the purity is caused by the love of nature. The pleasantry is as a way of expression. 2) The aesthetic values of the Korean traditional costume through the documentary studies stand for as the beauty of nature, the purity, the beauty of evil's eye, the beauty of symbolism, the beauty of personality, the beauty of tragedy and the beauty of tradition. 3) Korean traditional costume are perceived as clothes priority and open. 4) The aesthetic values of the Korean traditional costume can be re-defined as the beauty of nature, the purity, and the pleasantry. The beauty of nature comes from the 'natural' look, the exposure of the fabric as itself and the organic lines of the Korean traditional costume. The purity comes from the geometrical squared clothing form of Korean traditional costume which doesn't revive the human body form. The Pleasantry is seen the colors and motifs of costumes that have the human's hope and incantation and the exaggeration and distortion of human body form.

In this paper, coupling factors are calculated based on numerical analysis in order to assess various non-uniform low-frequency magnetic field exposure situations. Two types of non-uniform magnetic field sources are considered; circular coil and parallel wires with balanced currents. For each magnetic field source, source current values are determined so that reference magnetic field magnitude can be measured at the specified point on the human model. Various exposure situations are investigated by changing parameters such as the distance between source and human model, radius of circular coil, and the gap between parallel wires. For equivalent human models, prolate spheroid model and simplified human model from IEC 62311 standard are used. The calculated coupling factor values are compared with those obtained by 2D uniform disk human model, and the dependence of coupling factor on the choice of equivalent human model is analyzed.

This paper introduces the experimental results of ride values assessed for several passenger cars. The experiment was conducted at four vehicles on two roads for three persons by measuring the acceleration in the 12-axis of human. The results include the comparison of the ride values, such as the component ride values, overall ride value, and seat effective amplitude transmissibiity. It is proved that acceleration between 1 and 15Hz is the most significant in evaluating the ride quality. The contribution of the acceleration in each measurement axis is quantified from the component ride value. SEAT value shows a relatively low sensitivity for the road condition and human mass.

Choline is a water-soluble organic compound that is important for the normal functioning of the body. It is an essential dietary component as de novo synthesis by the human body is insufficient. Since the United States set the Adequate Intakes (AIs) for total choline as dietary reference values in 1998, Australia, China, and the European Union have also established the choline AIs. Although choline is clearly essential to life, the 2020 Dietary Reference Intakes for Koreans (KDRIs) has not established the values because very few studies have been done on choline intake in Koreans. Since choline intake levels differ by race and country, human studies on Koreans are essential to set KDRIs. Therefore, the present study was undertaken to provide basic data for developing choline KDRIs in the future by analyzing data on choline intake in Koreans to date and reference values of choline intake and dietary choline intake status by country and race.
