The current study was undertaken to determine the effect of retinoic acid (RA) on proliferation and differentiation of preadipocytes from male and female pigs. The preadipocytes were isolated from new-born male and female pigs by collagenase digestion and washed three times one day after seeding (designated as day 0 of culture). RA was included in the media at various concentratives from day 0 to 2. The cell number was measured on day 2 with hematocytometer after trypsin digestion. Cell differentiation was determined on day 6 by measuring glycerol-3-phosphate dehydrogenase activity. RA (0.1, 1 and 10 uM) showed no effect on proliferation of preadipocytes from both male and female pigs. However, RA significantly decreased differentiation of pig preadipocytes. Degree of differentiation with 0.1 uM, 1 uM and 10 uM of RA treatment was 80%, 41% and 29% respectively, compared with control. Similar inhibitory effect was found in the female pigs; 77%, 28% and 16% respectively. It is interesting that RA treated on cell proliferation stage had no effect on proliferation but had a strong inhibitory effect on differentiation which is happening in the late stage of cell culture.

이 연구의 목적은 남자 청소년의 ADHD성향과 인터넷 게임중독 간의 관계를 확인하고, 그 관계를 대인관계 형성과 인터넷 게임중독이 매개하는지를 검증하는 것이다. 연구대상자는 남자 중·고등학생 285명이었다. 이 연구를 위해 세계보건기구의 자기보고식 ADHD척도, 대인관계 유능성 척도, 인터넷게임중독선별검사 및 삶의 만족 척도를 사용하였다. 병렬적 이중 매개효과는 PROCESS Macro 3.5 모형 4로 분석하였다. 분석 결과, 남자 청소년의 ADHD성향은 대인관계 형성 및 삶의 만족과 각각 부적 상관이 있었으며, 인터넷 게임중독과는 정적 상관이 있었다. 남자 청소년의 대인관계 형성은 삶의 만족과는 정적 상관이 있었고, 인터넷 게임중독은 삶의 만족과 부적 상관이 있었다. 또한 남자 청소년의 ADHD성향과 삶의 만족 간의 관계를 대인관계 형성과 인터넷 게임중독이 이중으로 매개하는 것으로 나타났다. 본 연구의 결과는 ADHD성향이 강한 남자 청소년의 삶의 만족 수준을 향상하기 위해서 대인관계 형성과 인터넷 게임중독에 개입할 필요가 있음을 시사한다.

We have not identified on what gender difference during gait at a pace of one's preferred velocity effects on the function of bilateral lower limb. This study was undertaken to investigate a difference of gait strategy by gender during gait at a one's preferred velocity of participants of adult male and female (n=20). Cinematographic data for motion analysis, ground reaction force (GRF) variables, and muscle volume of lower limb were analyzed. Significant difference of variables on movement of center of mass whole body, joint angle and moment of lower limb, and ground reaction force were tested by 2-way ANOVA analysis (P<0.05). Male group showed more muscle volume than female, and both showed more volume in dominant leg than non-dominant. Main effect by bilateral leg during gait showed higher difference in right than left leg in change of vertical position of center of mass (maximal, minimal). Main effect by gender in vertical change of position and velocity of center of mass showed higher difference in male than female (maximal, minimal). Hip joint showed more flexed and extended angle in male than female, and also dorsiflexion of ankle and flexion moment of knee and hip joint showed higher in male than female group. Therefore, this result was assumed that dominant showed furthermore more contribution for propulsive function than non-dominant leg. Gender difference showed in strategy controlling of biomechanical characteristics, and perhaps influenced by muscle volume.

The purpose of this study is to investigate the effect of body type(thin, standard, fat), necktie width(narrow, medium, wide), gender(man, woman) on image formation. Sets of stimulus and response scales(7 point semantic) were used as experimental materials. The stimuli were 9 color pictures manipulated with the combination of necktie-width and body type using computer simulation. The subjects were 116 male undergraduates and 99 female undergraduates living in Gyeongsangnam-do. Image factor of the stimulus was composed of 4 different components, young-activity, attractiveness-gracefulness, stability, and boldness. In the young-activity, attractiveness-gracefulness and stability, body type and necktie-width showed independent effect. In the boldness, body type showed independent effect. Significant interaction effects of body type and necktie-width on young-activity, attractiveness-gracefulness and stability were found. For young-activity image, necktie of narrow width were effective. For attractiveness-gracefulness image, body type of standard were effective. For stability image, body type of standard and body type of thin on necktie of narrow and medium width were effective. The male fashion image can be perceived differently according to combination of the clues used in body type and necktie-width. Therefore, when the male fashion to create images that will have to consider the body type and necktie width.

This study examined the relationship between Korean male consumers' perceptions of marketing promotion investment such as advertising expenditure and celebrity endorsement are the brand equity elements. It also compared if there were differences on this research model and two groups that selected Korean or foreign country-of-brand-origin in fashion product purchasing. Online survey responses from 414 Korean men in their 20s-30s were analyzed using confirmatory factor analysis (CFA) and structural equation modeling analysis (SEM). Perceptions of advertising expenditures were found to be positively related to brand association in only the group that selected Korean country-of-brand-origin. The results showed a non-significant effect of perceptions for advertising expenditures on perceived product quality in both groups that selected Korean or foreign country-of-brand-origin. The results indicated that celebrity endorsement had a significant effect on brand association for the two male consumer groups. The results also demonstrated that the relationship of celebrity endorsement and perceived quality was significant in only a group that selected Korean country-of-brand-origin. The results also revealed that the effect of brand association and perceived product quality on brand preference was significant in both male consumer groups. This study has useful managerial implications for enhancing the effectiveness of investment in advertising activities.

The purposes of this paper are to investigate an effect of weight of material and gender on postural stability and to introduce formulas for those. There were five levels of weights 0, 9, 18, 27 and 36 kg, and two levels of genders were conducted. Eight male and five female subjects participated in this experiment, ten tests were performed for each level of weights to measure the postural stability by using the stability platform. The effect of the genders and the load on the postural stability were statistically analysed by the two way ANOVA test and the regression analysis. The ANOVA test showed that the effect of weights was statistically significant on postural stability to the both male and female subjects. And the postural stability of female subjects was better than that of male subjects. A linear regression formula for the balancing time and the load and a formula for the reduction rate postural stability and the relative load were introduced by the regression analysis.

The purpose of this study was to investigate the effect of family system on male adolescents' loneliness. From the research results significantly different factors of family system, consisting of family differentiation, family flexibility, boundary between parents and male adolescents, conflict resolved in parents, and male adolescents' cohesion with mother and father, explained each aspect of male adolescents' loneliness including lack of intimacy, social relationship network, and belonging according to their school types. The boundary between parents and male adolescents was a critical factor explaining the lack of intimacy of male adolescents in a juvenile detention center, and family flexibility was a congruous factor having an impact on the lack of belonging of male adolescents both in the juvenile detention center and public schools.

본 연구는 남, 여 알코올중독자의 외상경험을 살펴보고, 외상경험의 요인을 파악함으로써 사회복지의 실천적 토대를 제공하는 것을 목적으로 하였다. 이를 위해 220명의 알코올중독자를 대상으로 설문조사를 실시하였고, 위계적 회귀분석을 실시하였으며 그 연구결과는 다음과 같다. 첫째, 외상경험 내용을 살펴보면 남성의 경우 아동기 성적학대, 살아오면서 겪을 수 있는 외상(친밀한 사람의 자살, 사망, 질병, 가족분리)의 학대경험이 여성보다 많게 파악되었다. 반면 여성의 경우 아동기 신체적 학대, 정서적 학대, 성적 학대, 성인기 신체적 학대, 정서적 학대, 성적 학대, 살아오면서 겪을 수 있는 외상(사기, 신체적 방임, 유산)의 학대경험이 남성보다 많게 파악되었다. 또한 남성, 여성 알코올 중독자 모두 경제적 곤란의 외상경험을 한 것으로 나타났다. 둘째, 위계적 회귀분석 결과 남성 알코올중독자의 학력과 첫 음주연령이 외상경험에 영향을 주는 요인으로 확인되었다. 여성 알코올중독자의 경우 학력, 종교, 가족력, 재발경험, 병식이 외상경험에 영향을 주는 요인으로 확인되었다. 이러한 결과를 바탕으로 알코올중독자의 회복을 고취하기 위한 실천적 함의를 논의하였다.

본 연구는 간호남학생의 생활스트레스, 그릿, 대학생활적응 정도를 파악하고, 그릿의 매개효과가 생활스트레스와 대학생활적응의 관계에 미치는 영향을 파악하여 남자간호대학생의 대학생활 적응을 촉진하기 위해 수행되었다. 연구 대상자는 5개 도시의 간호학과 남자 간호대학생 209명으로 편의표집을 하였다. 수집된 데이터는 SPSS/WIN 25.0으로 분석하였다. 생활스트레스는 대학생활적응과 그릿에 유의한 부적 상관관계를 보였으나 그릿은 대학생활적응에 정적 상관관계로 나타났다. 매개효과 검증결과 최종모델은 대학생활적응의 43.5%를 설명하였다. 따라서 남자간호대학생의 대학생활적응을 향상시키기 위해서 생활 스트레스를 낮추고, 그릿과 대학생활 적응수준을 높일 수 있는 프로그램 개발이 요구된다.
