In order to help the marketers of the men\`s casual wear brands establish the marketing strategies to their target consumers, it is the purpose of this study to investigate on the variables affecting the casual wear purchase behavior of men in twenties, thirties and forties, and to clarify the differences of casual wear purchase behavior according to their age, The subjects were 429 men in their twenties, thirties and forties living in Seoul and data were analyzed by frequency, percentage, mean and standard deviation, x², ANOVA and Duncan\`s test. The results were as follows : (1) Significant differences were found among men in twenties, thirties and forties according to the self-image. Men in forties favored the conservative and not-noticeable image of casual wear, however, men in twenties and thirties favored those of the active, sexy, and distinctive image. (2) Significant differences were found among men in twenties, thirties and forties according to the importance of the store attributes such as convenience of transportation and parking place, clothing in vogue, and various merchandise. Men in thirties and forties put more importance on convenience of transportation and parking place. Men in forties put more importance on various merchandise than men in twenties and thirties. (3) Significant differences were found among men in twenties, thirties and forties according to general purchase behavior of casual wear. * Differences of the use of information according to age Majority of the men consulted the T.V., radio and people in their boundaries * Differences of the clothing purchase frequency according to age Men in twenties buy more clothing than other age groups. Men in twenties buy the clothing every one month and every three months and men in thirties and forties buy the clothing every three months and every six months. * Differences of the shopping day according to age Majority of the men buy the clothing on Saturday and Sunday. However men in twenties buy the clothing more on weekdays than other age groups. * Differences of the shopping place according There were not significant differences among three different age groups and majority of the men found out to utilize the department store. * Differences of the influence of the partners according to age Men in twenties found out to rely on their own decisions but men in thirties and forties found out to depend on their wives(loves). * Differences of the selection standards of casual wear according to age There were not significant differences according to age and adult males found out to select the casual wear by design, quality price in sequence.

There are big differences in six sigma applications between manufacturing processes and transactional processes. This paper analyzes the differences between two areas by examining 18 six sigma case studies in Korean companies. To characterize six sigma cases, a step-by-step checklist is developed based on 12-step DMAIC methodology proposed by US six sigma academy. On the basis of those characterized data, the differences between two areas are analyzed. The most significant differences is that statistical tools are widely used in manufacturing processes, but qualitative tools are used in transactional processes during improvement phase.

Gender differences have been given major attention in mathematics education in the context of pursuing gender equity in instructional and learning environment. It had been traditional belief that male students would outperform female students in mathematics, especially in the areas as geometry. This belief has been given doubts by cumulated empirical evidences that gender differences are gradually diminishing or even reversing its direction as time goes on. In this study, gender differences in geometry were explored using TIMSS 8th grade mathematics data administered in TIMSS 2003, 2007, and 2011, based on a cognitive diagnostic modeling(CDM) approach. Among various CDM models, the Fusion model was employed. The Fusion model has advantages over other CDM models in that it provides more detailed information about gender differences at the attribute level as well as item level and more mathematically tractable. The findings of this study show that Attribute 3(Three-dimensional Geometric Shapes) revealed statistically significant gender differences favoring male students in TIMSS 2003 and 2007, but did not show significant differences in TIMSS 2011, which provides an additional empirical evidence supporting the recent observation that gender gap is narrowing. In addition to the general trends in gender differences in geometry, this study also provided affluent information such as gender differences in attribute mastery profiles and gender differences in relative contributions of each attribute in solving a particular item. Based on the findings of the CDM approach exploring gender differences, instructional implications in geometry education are discussed.

The purposes of this paper are to present a selection method of neighboring pixels whose local statistics are similar to the center pixel and combine the selection result with mean curvature diffusion filter to reduce noises in remote sensed imagery. The order of selection of neighboring pixels is critical, especially for finding a pixel belonging to the homogeneous region, since the statistics of the homogeneous region vary according to the selection order. An effective strategy for selecting neighboring pixels, which uses rank-order differences vector obtained by computing the intensity differences between the center pixel and neighboring pixels and arranging them in ascending order, is proposed in this paper. By using region growing method, we divide the elements of the rank-ordered differences vector into two groups, homogeneous rank-ordered differences vector and outlier rank-ordered differences vector. The mean curvature diffusion filter is combined with a line process, which chooses selectively diffusion coefficient of the neighboring pixels belonging into homogeneous rank-ordered differences vector. Experimental results using an aerial image and a TerraSAR-X satellite image showed that the proposed method reduced more efficiently noises than some conventional adaptive filters using all neighboring pixels in updating the center pixel.

Purpose: This study aims to investigate how gender-based differences are actually reflected on drug approval. Methods: Data on gender-based differences of drugs were analyzed by searching PDR (Physician's Desk Reference) with the keyword, "GENDER". Results: There were descriptions related to gender in product directions of 361 drugs in 2009 PDR, out of which 63 items actually showed gender-related differences. Drug categories showing comparatively high gender-based differences were nervous system, cardiovascular system, and alimentary tract and metabolism. Pharmacokinetic differences between genders were observed most frequently; compared to men, 32 drugs showed higher absorption while 18 drugs revealed lower clearance in women. There were 2 drugs which gender should be considered before prescribing, and 5 drugs which showed different severity of adverse effects according to gender. Conclusions: It is necessary to establish domestic policies for drug approval and use which reflects gender-based differences through sufficient researches.

This review summarizes gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions. Gender differences in pharmacokinetics are categorized by four major factors: absorption/bioavailability, distribution, metabolism, and elimination. There are sex-based differences in gastric emptying time, gastric alcohol dehydrogenase activity, apparent volume of distribution, ${\alpha}1$-acid glycoprotein level, phase I (CYP) and phase II metabolizing enzymes, glomerular filtration rate, and drug transporters. This review also reports gender differences in pharmacokinetics and pharmacodynamics of cardiovascular agents, central nervous system acting agents and antiviral agents. In addition, it has been reported that females experience more adverse reactions such as coughing, tachycardia, nausea, vomiting, rash, hypersensitivity, hepatotoxicity, and metabolic disorder after taking cardiovascular, central nervous system acting and antiviral agents. Therefore, in order to provide optimal drug dosage regimens both in male and female, gender differences in pharmacokinetics, pharmacodynamics, and adverse drug reactions must be considered.

Despite research to treat delayed onset muscle soreness (DOMS), no effective treatment has been reported. The purpose of this study is to investigate the effect of a hold-relax technique and cryotherapy on DOMS. Thirty-three subjects were randomly assigned to one of three treatment groups: control, hold-relax technique, or hold-relax technique and cryotherapy. DOMS was induced in the non-dominant biceps muscle through repeated eccentric contractions. Resting elbow joint position, flexion and extension (universal goniometer), pain (Visual Analogue Scale; VAS), and WBC count (blood analysis) were measured one hour before DOMS was induced and 24, 48, and 72 hours after DOMS was induced. The data were analyzed by repeated measure of two-way ANOVA. The results of this study were summarized as follows: 1) While analysis showed no significant differences between groups in relation to a resting elbow joint position, there were significant differences over time, especially at 24, 48 hours after DOMS was induced compared with resting elbow joint position before DOMS was induced. 2) While analysis showed no significant differences between groups in relation to range of flexion, there were significant differences between range of flexion before DOMS was induced and range of flexion 72 hours after DOMS was induced. 3) There were no significant differences between groups or over time in relation to range of extension. 4) While analysis showed no significant differences between groups in relation to VAS, there were significant differences over time in different hours. 5) There were no significant differences between groups or over time in relation to WBC count. 6) There were no interactions between groups or over time in all variables. This results suggested that hold-relax technique and cryotherapy were not effective to reduce DOMS.

Purpose: This study examines and compares the differences between self-esteem and health promotion behavior of health department and non-health department college students. Method: The research instruments were as follows : The first one is RSES developed by Rosenberg and translated into Korean by Jeon. The second one is HPLP developed by Walker et al, and including six subareas by Lee and modified to be suitable to Korean culture by Suh. Data were statistically analyzed with SPSS PC/12.0. Results : 1. Comparison of self-esteem had no significant difference(p=.190) and health promotion behaviors had significant differences(p=.000) between the two groups. 2. According to general characteristics and health-related characteristics, the differences of self-esteem in health department showed significant differences in grade(p=.020), sex(p=.000), age(p=.000), parents' economic conditions(p=.048), and smoking(p=.030) while non-health departments revealed significant differences in grade(p=.003), sex(p=.000), age(p=.000) and smoking(p=.001). 3. According to general characteristics and health-related characteristics, the differences of health promotion behaviors in health department showed significant differences in grade(p=.008), sex(p=.021), age(p=.000) and parents' economic conditions(p=.017) while non-health department revealed significant differences in sex(p=.000) and age(p=.000). 4. There were positive correlations between self-esteem, health promotion behaviors and subareas in health department (r=.422) and non-health department (r=.383). Conclusion: There were significant positive correlations between self-esteem and health promotion behaviors in health and non-health department college students. Therefore, health related programs should be developed to enhance self-esteem and health management by college students can influence themselves on self-esteem and health promotion behaviors.
