중국여성들의 한류(韓流)에 대한 인식도를 기준으로 '고집단'과 '저집단'으로 나누어 한국 화장품에 대한 품질인식과 구매행동을 분석함으로써, 중국내 마케팅 전략수립을 위한 시사점을 도출하고자 하였다. 중국 광저우시에 거주하는 중국 여성을 대상으로 한 설문조사 결과를 k-평균 군집분석, 독립표본 T 검정, 요인분석 등의 연구방법으로 분석하였다. 한류가 품질에 대한 인식과 브랜드이미지 제고에 미치는 긍정적 효과는 저집단보다 '고집단'에게 훨씬 더 강력하였고, 사용 후 만족도와 구매 추천 의향으로까지 연결되는 것으로 나타났다. 두 집단 간 품질 인식과 구매행동 등에 있어 큰 차이를 보여, 지역별 계층별 한류 인지도의 차이에 따라 마케팅 전략을 차별화할 필요가 있음을 시사한다. 다만, 두 집단 모두에게 저렴한 가격이 가장 중요한 구매 동기로 나타나, 한류의 확산과 함께 한국 화장품의 품질과 브랜드의 고급 이미지를 강화하기 위한 노력이 절실하게 필요한 것으로 사료된다.

Although women's economic participation has been increasing in Korea, the utilization of educated women's labor is still low. Therefore, vocational training programs for women are both important and necessary. This study examines the vocational training programs for women offered by the three largest vocational training centers in Jeju: the Woman Resources Development Center, the Jeju Women's Development Center, and the Seogwipo City Women's Cultural Center. This study also analyzes the students' satisfaction with these vocational training programs and identifies the related variables that cause differences in their levels of satisfaction. The sample includes 397 respondents who were surveyed from June 23 to September 12, 2008. Moreover, the data are analyzed by conducting a one-way ANOVA, t-test, and Duncan's Multiple Range(DMR)test. The major results of the study are as follows. First, the vocational training programs in Jeju consist of lectures that cover various subjects. The programs mainly focus on work that offers relatively low wages and requires few skills, and the duration of the programs is short. Second, the original goal of the programs does not meet the needs of women who are seeking employment. The participants respond that they want more appropriate programs that are designed by considering their need for employment, support them in finding a job, and re-educate them. Third, most of the participants are satisfied with their vocational training experiences, and their satisfaction with the instructors is especially high. The differences in their levels of satisfaction are caused by economic characteristics such as the location of the student's residence, home ownership, and the level of life. The results of this study suggest that there is a need to separate vocational/employment training from general education for women. Moreover, the vocational training programs for women should be more specialized according to the different needs of each group.

The effects of dietary mannan oligosaccharides, Lactobacillus plantarum, Bacillus subtilis, and Bacillus licheniformis supplementation on hybrid grouper Epinephelus akaara ♀×Epinephelus lanceolatus ♂ were evaluated. The fish were fed a basal diet and five other diets consisting of 0.6% mannan oligosaccharides, L. plantarum, B. subtilis, and B. licheniformis and mixture of each 0.15% prebiotic and all the probiotics (designated as MOS, LP, BS, BL, and SYN) for 56 days. Growth performance and feed utilization showed no significant differences among all experimental groups. Lipid level of whole-body was significantly high in MOS and BL groups. Plasma aspartate aminotransferase was significantly low in BL and SYN groups. Nitro-blue tetrazolium, lysozyme and anti-protease, and glutathione peroxidase in BS, SYN, and all probiotic groups, respectively, were significantly high. Intestinal Vibrio bacteria was significantly low in all probiotic and SYN groups. Gene expression of interleukin-1β and interleukin-10 in SYN group; transforming growth factor β2 in MOS and BS groups, toll-like receptor 2-2 in BS and BL groups; and C-type lectin in MOS, LP and SYN groups were significantly upregulated. Our findings indicate that mannan oligosaccharides, L. plantarum, B. subtilis, and B. licheniformis could improve innate immunity, antioxidant capacity, anti-inflammation, and intestinal microbiota of hybrid grouper.

Thirty-six yearling (18 bulls, 18 heifers) swamp buffaloes (Bubalus bubalis) with average liveweight $177{\pm}26kg$, were randomly allotted to receive 6 dietary treatments according to a $2{\times}3$ factorial arrangement in a completely randomized design (CRD). Factor A assigned for two types of straw; untreated rice straw (RS) and urea-treated (5%, w/w) rice straw (UTS). Factor B assigned for three ratio of roughage to concentrate (R:C) at 80:20, 50:50 and 20:80. Feeding trial lasted for 9 months during which respective feeds were offered at 3% body weight and adjusted at bi-weekly intervals using corresponding liveweights. Parameters measured under this experiment were feed intake, ruminal fluid for pH, $NH_3-N$, volatile fatty acids (VFA), liveweight change at bi-weekly intervals, carcass characteristics and cost-net profit analysis. It was found that intakes and digestion coefficients of DM, OM, CP except NDF and ADF were improved appreciably when ratio of concentrate increased. The average daily gain (ADG) and feed conversion ratio (FCR) were highest in group fed urea-treated rice straw at R:C levels of 20:80 (551.2 g/d, 10.7 kg/kg) and 50:50 (542.3 g/d, 10.6 kg/kg). It was obvious that FCR was best in the group fed on urea-treated rice straw (13.8 kg/kg) as compared to untreated rice straw fed-group (24 kg/kg). Carcass compositions of buffaloes measured resulted in 48.2 dressing percentage in all treatments offered at R:C levels of 50:50 and 20:80, however, loin eye area were 46.0, 53.6, 50.0 and $54.0cm^2$ for RS and UTS at respective levels of R:C. It was notable that carcass fat content was low which resulted in higher content of lean meat particularly in group fed UTS at 50:50 ratio R:C. Simple cost-net profit analysis was performed, it was found that net profits were obtained as follows 27, 30, -47, 44, 58, 22 $US/hd for respective treatment groups of RS and UTS at respective R:C levels. As shown, the best net profit resulted in group fed UTS at 50:50 R:C level.

This study was carried out to establish an optimum number of phase feeding regimen which enable to reduce nutrients excretion without affecting growth performance and to investigate the effects of different feeding regimens on growth performance, nutrients excretion and carcass characteristics in finishing pigs. A total of 120 finishing pigs (an average initial body weight of 54.3 kg) were assigned to the feeding trial and 12 pigs were assigned to the metabolic trial. Treatments included one phase (54 to 104 kg), two phase (54 to 80 and 80 to 104 kg), three phase (54 to 70, 70 to 90 and 90 to 104 kg) and four phase (54 to 65, 65 to 80, 80 to 95, 95 to 104 kg) feeding regimens. Experimental diets were formulated to contain 16% crude protein for one phase feeding regimen, 16% and 12% crude protein for two phase feeding regimen, 16%, 14% and 12% crude protein for three phase feeding regimen, and 16%, 14.7%, 13.4% and 12% crude protein for four phase feeding regimen, respectively. Although there were no significant differences in any criteria measured during the entire experimental period, pigs reared in three phase feeding regimen grew slightly faster than those reared in other feeding regimens and showed a tendency to increase ADFI during the whole experimental period. The metabolic trial indicated that there were no significant differences in DM (dry matter), CP (crude protein) and P (phosphorus) digestibilities. However, fecal nutrient excretion except P was significantly influenced by feeding regimens. DM excretion of one phase feeding group was significantly higher than that of three phase feeding group and daily fecal N (nitrogen) excretion of one phase feeding group was higher than that of other phase feeding groups (p<0.05). Three and four phase feeding regimens resulted in 12% lower fecal N and DM excretion than one phase feeding regimen. Blood urea concentrations were lower for pigs reared in two, three and four phase feeding regimens than for those reared in one phase feeding regimen (p<0.05). Three phase feeding regimen for the finishing period showed better carcass grade than one phase feeding regimen, though the difference was not significant. The tenth rib fat thickness of pigs fed on four phase feeding regimen was reduced most and there was a trend that backfat thickness decreased as the number of phases increased. Feed cost per kg weight gain was significantly low in four phase feeding group than one phase feeding group (p<0.05). In summary, it seemed that producers generally oversupply the expensive nutrients for the finishing pigs. High nutrient diets do not always guarantee high growth rate of pigs and cause more unwanted nutrient excretion. It rather seems that meeting nutrient requirements for the each growth phase is more important for the reduction of pollutants and economical pork production.
