This study provides size information on current imported medical compression stockings in Korea. A total 20 brands from 6 countries imported and sold in the Korean on-off line markets were selected for this study and the sizing system of medical compression stockings was researched. The results of this study were as follows: there were size differences among different USA brands according to product type or compression class of medical compression stockings. To establish the sizing system for medical stockings of the German brands, the basic body measurements standard was set as cA, cY, cB, cB, cC, cD, cE, cF, cG, cH, cT, lD, lG, and lT. Italian brands developed the sizing system for medical compression stockings by compression class. In the Swiss brands, size types were sub-divided as 'Normal', 'Plus', 'Short', and 'Long'. The sizing 1 were confined within very narrow limits. There were differences of the basic body measurements between Taiwan brands. The results of the comparison of the size range of the imported brands with Size Korea (KATS, 2010) by two-way size distribution shows that the sizing systems of the imported brands were unsuitable for Koreans. To enhance the suitability of the sizing system for medical compression stockings, a new sizing system for Korean adult males and females needs to be established.

Pharmacokinetics and oral bioavailability of levosulpiride was determined in Korean healthy male volunteers. Thirty subjects received a single oral dose (25 mg) of a tablet in a randomized $2{\times}2$ cross-over design. The plasma concentrations of levosulpiride were measured by HPLC and compared with those reported in the literature. Pharmacokinetic parameters for $Isomeric^{\circledR}$ tablet (levosulpiride 25 mg) were revealed as follows: $AUC_{inf}\;737.1{\pm}176.9\;ng{\cdot}hr/ml,\;C_{max}\;56.4{\pm}20.1\;ng/ml,\;T_{max}\;4.2{\pm}1.6\;hr,\;K_a\;1.00{\pm}1.09\;hr^{-1},\;K_{el}\;0.08{\pm}0.02\;hr^{-1},\;and\;t_{1/2}\;8.8{\pm}1.9\;hr$. The rate constant of the absorption phase was obtained based on the first-order kinetics. In the aspect of bioavailability, $Isomeric^{\circledR}$ tablet was bioequivalent to the other product $(Levopride^{\circledR}\;tablet)$ available in the Korea market. Intersubject variations and race differences were show in comparison with the published data in the literature, even though there was a linear relationship between dose ad extent of bioavailability.

This research is an in-depth study on the differences of cosmetics advertising and brand representation between Korean companies and Chinese companies. In addition, it studies the preferences of cosmetics consumption in Korea and China. To study these topics, two major methods are applied to magazine advertising analysis and consumer research. Analysis objects are the magazine advertisements of the Korean brands Mamond and Laneige, which entered the China market more than 5 years ago; the 64 advertisements are evenly split between Koreans and Chinese. The objects of the survey are 470 females between the ages 20 and 30 (237 from Korea and 233 from China). The results were as follows. First, Chinese advertisements use intense appeal in which the types of advertisement appeal are highly preferred. Second, ordinary models are highly preferred. Second, (on the nationality of the models) Chinese and Korean models are preferred in comparison to western models. Third, (as shown in the survey) Koreans and Chinese preferred magazine advertisements with headlines and copies. Four, blue colors are commonly used in the advertisements; however, the survey shows that the Chinese consumers prefer gray colors. Furthermore, from this study, there is a significant dynamic between the brand image and consumer satisfaction as well as the re-purchase intention.

Korean certification regulation for particulate filtering respirators requires inward leakage (IL) test as European Standards (EN) and the standard levels of regulation are the same as those of EN. This study was conducted to evaluate particulate filtering respirators being commercially used in the market by using IL and assess the characteristics of IL. The study began with discussing the concept of IL, comparison of IL with fit test, and IL measurement method. Three brands of half masks and 10 brands of filtering facepieces (two top class, four 1st class and four 2nd class), total 13 brands respirators, and 10 test panels (subjects) who were classified in 9 facial grids in accordance with face length and lip length, were selected for IL test. IL tests were conducted in the laboratory of 3M Innovation Center which was established by EN standard. As expected ILs of half masks were lower than those of filtering facepiece mask. ILs of half masks and some filtering facepieces were significantly different in manufacturers. ILs of 1st class filtering facepieces were found to be much more than those of 2nd class and thus the result would cause wearers to get confused to select a mask. Four of six brands being no compliance with standards were thought that they should be tested again for certification because of a lot of differences from standards. There were no significant differences among ILs of five exercises. In 6 out of 13 brands lognormal distribution of ILs may be a better fit distribution and in 7 brands both lognormal and normal distributions were rejected. The result indicates that geometric mean may be better than arithmetic mean to establish standard.

Purpose: Car seats affect customer satisfaction greatly when the seats' design is changed because car holders are in close contact with the seats. However, the improvement of the current seats' design involves risks such as investment cost, and therefore it needs strategic operating measures from the perspective of customers. Until now, operations of seats' specification have been decided by technical-push rather than market-pull, and carried out based on professionals' experience without measuring customer satisfaction correctly. The purpose of this study is to present a systematic approach to measure customers' perception on the car seats using the Kano model and pairwise comparison technique. Methods: The authors derive 17 major functions of a car seat by analyzing major components of car seats, and conduct a survey of 141 adults who hold a car(s). Results: The results show that consumers perceive the adjustable functions of front seats as must-be while the same functions for rear seats are perceived as attractive. In particular, motor operated functions for both front and rear seats increase customer satisfaction greatly if they are presented. Conclusion: This study shows that how much customer (dis)satisfaction will increase if a function of car seats (non)fulfilled, and therefore, the results of this study will provide practitioners and R&D personnel in new automobile seats development projects with useful information.

Power Metal Oxide Semiconductor Field Effect Transistor's (MOSFETs) are well known for superior switching speed, and they require very little gate drive power because of the insulated gate. In these respects, power MOSFETs approach the characteristics of an "ideal switch". The main drawback is on-resistance RDS(on) and its strong positive temperature coefficient. While this process has been driven by market place competition with operating parameters determined by products, manufacturing technology innovations that have not necessarily followed such a consistent path have enabled it. This treatise briefly examines metal oxide semiconductor (MOS) device characteristics and elucidates important future issues which semiconductor technologists face as they attempt to continue the rate of progress to the identified terminus of the technology shrink path in about 2020. We could find at the electrical property as variation p base dose. Ultimately, its ON state voltage drop was enhanced also shrink chip size. To obtain an optimized parameter and design, we have simulated over 500 V Field ring using 8 Field rings. Field ring width was $3{\mu}m$ and P base dose was $1e15cm^2$. Also the numerical multiple $2.52cm^2$ was obtained which indicates the doping limit of the original device. We have simulated diffusion condition was split from $1,150^{\circ}C$ to $1,200^{\circ}C$. And then $1,150^{\circ}C$ diffusion time was best condition for break down voltage.
