I examined the relationship between allocations to plant size components such as plant height, total leaf weight, and nuber of branches and to reproductive components such as the number and weight of male and female fowers in three populations of the monoecious, wind-pollinated Ambrosia artemisiifolia. In particular, the two types of gender of plants, phenotypic and functional gender, were related to resource allocation. Mean values of all plant size and reproductive components differed significantly among the three populations. Such inter-population differences did not exist for both photosynthetic and reproductive efforts, Plant size components were mostly positively correlated with reproductive components among plants. However, the relationships between photosynthetic effort and reproductive components were largely negative and inconsistent among populations. The phenotypic gender was much lover than 0.5 in all of the three populations. Pairwise correlations between functional gender and each allocation measurement such as plant size components, reproductive components, photosynthetic effort, and reproductive effort were not consistent across the three populations. These results suggest that the gender of A. artemisiifolia measured as flower production responds sensitively to environmental conditions which might differ whithin as well as among populations.

The Tridosha theory, which is the cornerstone of Ayurvedic physiology governs all the functions of human body and mind. Tridosha are responsible in determining one's Prakriti and their functional status may vary in both gender of different Prakriti. No research work is available to assess the functions of Dosha by objective parameters. Therefore, this study was planned to find out the variation in functional status of different types of Pitta, using certain objective parameters, in 201 young healthy volunteers of both gender belonging to different Prakriti. Serum level of triglycerides, cholesterol, total protein and glucose level were estimated for Pachaka Pitta and hemoglobin concentration for Ranjaka Pitta, visual acuity for Alochaka Pitta, memory and reaction time for Sadhaka Pitta and RGB value for Bhrajaka Pitta were measured. Except the functioning of Bhrajaka Pitta, variation in functional status of all type of Pitta was not the same in different Prakriti of both gender. However these findings were not significant which may have occurred due to small sample size and homogenous population. Thus we propose the consideration of sex differences while planning and evaluating the studies that are based on Prakriti.

Mobile Entertainment is the new era in mobile communication. Mobile Entertainment service is a combination of games, music, videos, chatting and telecommunication which has created a wide market in India. There is a variation between male and female customers towards Mobile Entertainment services. This study is aimed at analyzing gender impact of attitude, subjective norm, perceived behaviour control intention and behaviour towards mobile entertainment services. The Theory of planned Behaviour (TPB) provided a framework. Total 566 male and 376 female mobile users of different age groups participated in the research. The data analysis was conducted in three-stages. First, reliability tests were performed. Upon satisfactory results, confirmatory factor analysis (CFA) is used to analysis convergent, concurrent and discriminant validity of the model. Once the model was validated Structural Equation Model (SEM) Multi-group analysis is used to find the impact of gender behaviour towards Mobile entertainment services. The results of the study confirmed that the model is viable in predicting variation in gender impact on mobile entertainment services. The findings have revealed that attitude, perceived behaviour control and intention has a significant impact on behaviour to use mobile entertainment but subjective norm has no significant impact on behaviour to use mobile entertainment.

This study aims to characterize the effect of different combinations of chromatic-achromatic colors and 1:2:3 area-ratio variation of stripe necktie, and gender on the image of male wearer. The experimental materials developed for this study are a set of stimuli and response scales. The stimuli consist of 84 color pictures manipulated with every combination of 12 different colors and 7 different area-ratio. The 7-point scale designed for visual evaluation of image formation included 26 bipolar adjectives. The subjects were 2016 undergraduate students in Gyeongnam, Seoul, Busan, and Daegu areas. The results of this study were as follows. The analyses of images of male wearer in terms of combinations of chromatic-achromatic colors and I :2:3 area-ratio variation of oblique stripe necktie reveal that the concerned factors are of five characteristic dimensions of youth-activity, ability, attractiveness, appeal, and warmness. In addition, it has been found that individual images of male wearer are affected by observer's gender as well as combinations of chromatic-achromatic colors and 1:2:3 area-ratio variation of stripe neckties and that those images vary with every combination of each factor. The study results are highly expected to be used as useful sources in developing necktie designs.

Objectives : This study was undertaken to examine the metabolomic changes due to gender and diurnal variation at sampling time and to identify an appropriate time point for urine sampling in epidemiologic studies using metabolomic profiles. Methods : Urine samples were collected twice a day (morning and afternoon) from 20 healthy Korean adults after fasting for 8 hours. The metabolomic assay was investigated using $^1H$ NMR spectroscopy coupled with the principal components analysis (PCA) and partial least squares discriminant analysis (PLS-DA). The metabolites responsible for differentiation between groups were identified through the loading plot of PLS-DA and quantified using Chenomx NMR Suite with a 600 MHz library. Results : Metabolites responsible for differentiation in gender and sampling time were creatinine, trimethyl anine oxide (TMAO), hippurate, mannitol, citrate and acetoacetate. Dimethylamine showed difference only as a factor of diurnal time. The level of creatinine was higher in men compared to women, and the levels of citrate, TMAO, hippurate, mannitol, and acetoacetate were higher in women compared to men. The levels of creatinine, TMAO, hippurate, dimethylamine and mannitol were higher in the morning rather than the afternoon while those of citrate and acetoacetate were higher in the afternoon rather than the morning. Conclusions : Since urinary metabolomic profiles varied by gender and diurnal cycle, urine sampling should be performed at the same time point for all participants in epidemiologic studies using metabolomic profiles.

The carcass size performances and the meat quality of Gannan and Sibu yak were determined using M. supraspinatus (SU), M. longissimus thoracis (LT) and M.quadriceps femoris (QF). It is found that Sibu yak had significantly higher carcass weight (CW) than Gannan yak with difference of nearly 40 kg, as well as significantly higher eye muscle area (EMA), carcass thorax depth (CTD), round perimeter (RP), etc. The carcass performances of steer yak were significantly higher than heifer yak except meat thickness at round (MTR) (p<0.05). The results show that both yak breed and gender had significant effects on carcass performances. It could be seen that the variation of carcass size performances from breeds is as large as from gender (50.22% and 46.25% of total variation, respectively) through principal component analysis (PCA). Sibu yak had significantly higher L*, b*, WBSF, cooking loss and Fat content, while Gannan yak had significantly higher a*, press loss, protein content and moisture (p<0.05). Yak gender and muscle had insignificant effects on meat colour and water holding capacity (p>0.05). The variation of meat quality of yak from breed is up to 59.46% of total variation according to PCA. It is shown that the difference between breeds, for Gannan yak and Sibu yak, plays an important role in carcass size performance and meat quality.

본 논문에서는 성에 따른 취업자의 지역별 통근율의 차이와 취업기회의 차이에 대한 분석을 통한 성에 따른 직주분리의 정도와 이에 의한 통근통행행태의 차이가 설명되었다. 분석결과 남성취업자의 경우 직장과 거주지의 위치에 따른 공간적 제약이 이들의 취업과정에 별다른 영향을 미치지 않는 반면 여성취업자의 경우는 직장과 거주지의 위치에 따른 공간적 제약이 이들의 취업과정에 영향을 미칠 수 있는 것으로 나타나고 있다. 취업과정에서 나타나는 공간적 제약의 성에 따른 차이는 곧 성에 따른 직주분리의 정도의 차이를 유발하여 여성취업자가 남성취업자에 비하여 상대적으로 직주분리의 정도가 적은 것으로 나타나며 이러한 직주분리의 차이는 다시 이들의 통근통행행태에도 영향을 미친다. 즉 일반적으로 남성통근자는 여성통근자에 비하여 보다 장거리 통근을 하며, 보다 많은 통근비용을 지출하고 또한 상대적으로 고급의 통근수단을 이용하고 있는 것으로 나타난다.

The present study investigated whether there are differences in articulation rate by gender, age, and individual speakers in a spontaneous speech corpus produced by 40 Seoul Korean speakers. This study measured their articulation rates using a second-per-syllable metric and a syllable-per-second metric. The findings are as follows. First, in spontaneous Seoul Korean speech, there was a gender difference in articulation rates only in age group 10-19, among whom men tended to speak faster than women. Second, individual speakers showed variability in their rates of articulation. The tendency for some speakers to speak faster than others was variable. Finally, there were metric differences in articulation rate. That is, regarding the coefficients of variation, the values of the second-per-syllable metric were much higher than those for the syllable-per-second metric. The articulation rate for the syllable-per-second metric tended to be more distinct among individual speakers. The present results imply that data gathered in a corpus of Seoul Korean spontaneous speech may reflect speaker-specific differences in articulatory movements.

이 연구는 주요 일간지에서 기자 개인의 성별과 조직의 성비라는 두 요인이 여성인물의 보도에 어떤 차이를 유발하는지 검토하였다. 편집국의 기자 여성비를 고려하여 <<문화일보>>, <<조선일보>>, <<한겨레신문>>을 분석대상으로 선정하였다. 분석결과, 남성기자보다 여성기자가 다양한 직업군의 여성인물을 더 심층적이고 긍정적으로 그린다는 사실을 알 수 있었다. 여성인물 보도방식은 신문사 조직 수준의 여성비와도 관련 있었는데, 기자 여성비가 높은 신문에서 상대적으로 더욱 여성 우호적인 보도경향을 관찰할 수 있었다. 아울러, 편집국의 여성비 증가가 여성기자보다 남성기자의 보도방식에 더 큰 변화를 가져온다는 사실도 확인하였다. 여성의 언론계 진출 증가가 여성보도에 제기하는 함의를 논의하였다.
