Response contents analyzed to 506 people except imperfect questionnaire. Data used windows sas 8.0 program and did descriptive statistical analysis. Results: There is a meaningful difference in what they want to know about an occupation according to ages. (${\rho}$ < 0.01) All ages are similar to their occupational thinking, however they who are under twenties consider working environment. Most motives of an entrance are similar, there is a meaningful difference. (${\rho}$ < 0.05) According to a grade of college, there is a meaningful difference how to obtain informations of a career. (${\rho}$ < 0.05) Sophomores and juniors obtain information from seniors or family, however freshmen obtain from the internet because of an accessibility. There is a meaningful difference of a job meaning between men and women. (${\rho}$ < 0.01) Men are working for a means of living. But women give weight to a self-development. The older they grow, the more they know about their aptitude. Selecting subjects are different choosing time & motive. According to ages and where they are from, there is a meaningful difference how much know about their aptitude. (${\rho}$ < 0.05) Older Students know more than young students. Selecting subjects are different choosing time & motive. In accordance with a grade, ages, and where they are from, there are different degrees about how much know their interests. There is a meaningful difference of a choosing major period and choosing informations. (${\rho}$ < 0.01) And also there is a meaningful difference where they are from and why they enter to College. (${\rho}$ < 0.001) In accordance with a grade, ages, and where they are from, there are different degrees about how much know their aptitude. There is a meaningful difference of a choosing major period. (${\rho}$ < 0.01) And also there is a meaningful difference why they enter to College. (${\rho}$ < 0.001) Conclusion: Although we know that a career education is very important, however lots of students select a career without their aptitude & interest & character. We need to teach a career education systematically; considering students career consciousness, with a proper career guidance, cultivating career consciousness.

Korea's clothing industry which has been country's leading export industry and basic strategical industry is now faced with many difficulties both domestically and internationally. Domestically it is faced with continuing shortage of manpower in both production line and management high labour cost causing increase in price putting more weight on behavior of consumers resulting in change of industrial environment and continuing structural problems of industry itself. Internationally it is faced with strengthening of import regulations and protectionism of developed countries and rapid emergence of underdeveloped countries as leading exporting nations. In reality export plays the most essential role in our economy and is especially sensitive to the external environmental factors. Already economic bloc phonomenon can be seen everywhere and is continuing to accelerate in place such as E. U in Europ, North & South America as NAFTA, and South East Asian contries which recent tendency of economic unity effort is present. These countries of such economic blocs are imposing heavy custom duties reinforcing provision of country origin and acting out strict inspection regulations in order to protect the interest of their own industry. Therefore it is vital to manufacture excellent quality goods For these reasons study in this area has brought attention in Korea as well as worldwide in the recent years. Apparel industry which requires professional technology and ability is the most competitive international business. In order to challenge the international market the high level of intelligence is most required to produce high quality goods. The purpose of this study is to analyze the relationship between functions and roles of marketing and to approach problems in more efficient manner. Apparel industry is composed of various programs such as design pattern making merchandising and textile science. To succeed in the business is to give the highest satisfaction to the targeted market. Hence this study will example the factors that determine the Cost Quality and Performance of apparel products.

Insects and their extract have been traditionally used as medicinal resources in Asia. Recently, Gryllus bimaculatus and the larva of Tenebrio molitor, Protaetia brevitarsis, and Allomyrina dichotoma were enlisted as general food ingredients by Korean Ministry of Food and Drug Safety. As the interest in these insects is growing, the detailed investigation is needed for the standardization of suitable and safe rearing techniques. This survey was conducted via personal interviews about edible insect rearing farms in Korea. The basic feed is fermented oak sawdust for P. brevitarsis and A. dichotoma and wheat bran for T. molitor. The various feed additives are blended with each farm's own recipes. The overall growth condition, including sawdust fermentation method, feeding period, and rearing density, varies among the investigated farms. It seems that weight of last instar larva was correlated with the rearing density and duration of the larval period. The heavy metal contents were analyzed after 48 hour starvation and they were very small amount or not detected in investigated insects. We believe that the present data will contribute to develop and standardize the safe rearing techniques of edible insects in Korea.

This study was conducted as a comparative analysis, using the SPSS 17.0 program for a survey conducted from March to July 2013, on the level of perception and preference factors of Koreans and Americans residing in Virginia, USA(89 male and female adults of 20 years of age or above). For the information on the degree of obesity, a survey was used and the subjects provided with their heights and weights. The researcher used this data to calculated their BMI and distinguished the degrees of obesity. For the BMI, the obesity diagnosis of Korean Society for the Study of Obesity was used for Koreans, and the WHO's obesity diagnosis on adults were employed for Americans. First, regarding the Korean participants, the level of obesity appeared in the order of normal (79.6%), overweight (14.3%), and underweight (6.1%). Also, the level of perceptions of their health conditions appeared in the order of average (51.7%) and good (34.7%). No one perceived their health to be in poor condition. Meanwhile, for the American participants, the order was as follows: overweight at about 45%, normal weight at about 35%, obesity at about 12.5%, and underweight at about 7.5%. In terms of the level of perception of health during ordinary times, about 55% of the American participants answered that they are in good health. Therefore, the Americans were found to perceive their health to be in relatively better condition than the Koreans residing in the USA. Also, concerning the level of interest in health while eating food at ordinary times, the American participants were discovered to be more interested (about 62.5%) than the Korean participants. The research on their preference for salty taste was conducted as a survey, and the subjects were asked to choose an item according to their subjective feeling. Regarding the preference for salty taste, both Koreans and Americans residing in the USA responded as moderate. However, a higher proportion of Americans than Koreans responded to favor salty taste. Concerning the reason for their preference for salty taste, Koreans responded with various reasons whereas Americans mostly responded that it is because they eat salty food frequently. For any changes in dietary behavior related to eating salty food, both Korean and American respondents thought that the amount of their daily intake of salt is appropriate and that they consider taste as most important in selecting a snack. Based on the above data, the results of this research indicate a need for actual improvement in the diet with regard to salty food along with diverse policies for promoting life with a low salt diet in future.

Recently the global epidemic problem of obesity has stimulated intense interest in the study of physiological mechanisms using animal models as a way to gain crucial data required for translation to human studies. Panax ginseng has been reported to have anti-obesity or antidiabetic effects in many animal studies; however, there have been few studies investigating human obesity. Herein, we will assess and examine the evidence supporting the anti-obesity effect of Panax ginseng in animal models with respect to anthropometric and metabolic outcomes. We will include controlled, comparative studies assessing the effect of Panax ginseng in preclinical studies of obesity. Panax ginseng will be administered during or following the induction of experimental obesity. The primary outcome measure will be anthropometric assessment and the secondary outcome measures will include adipose tissue weight, total amount of food consumed and metabolic parameters. We will search MEDLINE, Embase, PubMed, Web of Science, and Scopus without language, publication date, or other restrictions. Ethical approval will not be necessary as the data collected in this study will not be individual patient data, consequently there will be no concerns about violations of privacy. After finishing the whole procedure, the results will be disseminated by publication in a peer-reviewed journal or presented at a relevant conference. This protocol has been registered on the Collaborative Approach to Meta-Analysis and Review of Animal Data from Experimental Studies (CAMARADES) website (http://www.camarades.info).

The breakwaters are designed by considering the cost optimization because a human risk is seldom considered. Most breakwaters, however, were constructed without considering the cost optimization. In this study, the optimum return period, target failure probability and the partial safety factors were evaluated by applying the cost optimization to the rubble mound breakwaters in Korea. The applied method was developed by Hans F. Burcharth and John D. Sorensen in relation to the PIANC Working Group 47. The optimum return period was determined as 50 years in many cases and was found as 100 years in the case of high real interest rate. Target failure probability was suggested by using the probabilities of failure corresponding to the optimum return period and those of reliability analysis of existing structures. The final target failure probability is about 60% for the initial limit state of the national design standard and then the overall safety factor is calculated as 1.09. It is required that the nominal diameter and weight of armor are respectively 9% and 30% larger than those of the existing design method. Moreover, partial safety factors considering the cost optimization were compared with those calculated by Level 2 analysis and a fairly good agreement was found between the two methods especially the failure probability less than 40%.

Brazzein is the smallest sweet protein and was isolated from the fruit pulp of Pentadiplandra brazzeana Baillon, native to tropical Africa. From ancient times, the indigenous people used this fruit in their diet to add sweetness to their daily food. Brazzein is 500 to 2000 times sweeter than sucrose on a weight basis and 9500 times sweeter on a molar basis. This unique property has led to increasing interest in this protein. However, it is expensive and difficult to produce brazzein other than in its native growing conditions which limits its availability for use as a food additive. In this study, we report high production yields of, brazzein protein in transgenic rice plants. An ORF region encoding brazzein and driven by the $2{\times}CaMV\;35S$ promoter was introduced into rice genome (Oryza sativa Japonica) via Agrobacterium-mediated transformation. After transformation, 17 regenerated plant lines were obtained and these transgene-containing plants were confirmed by PCR analysis. In addition, the selected plant lines were analyzed by Taqman PCR and results showed that 9 T0 lines were found to have a single copy out of 17 transgenic plants. Moreover, high and genetically stable expression of brazzein was confirmed by western blot analysis. These results demonstrate that recombinant brazzein was efficiently expressed in transgenic rice plants, and that we have developed a new rice variety with a natural sweetener.

Currently, there is a growing interest among consumers in selecting healthier meat with a greater proportion of essential fatty acids (FA). This experiment was conducted to evaluate the role of different ratios of dietary n-6:n-3 on growth performance, FA profile of longissimus dorsi (LD), relative gene expression of cytokines, meat quality, and blood parameters in finishing pigs. A total of 108 finishing pigs was randomly allotted to three treatments including a control (basal diet) and low ratios (4:1 and 2:1) of n-6:n-3. The 4:1 and 2:1 diets decreased the overall stearic acid in LD. There were reductions in the content of stearic acid, palmitoleic acid, total saturated acid, and n-6:n-3 ratio of LD in pigs fed 4:1 and 2:1 diet compared with the control diet. The 4:1 and 2:1 diets increased the concentration of α-Linolenic acid and polyunsaturated FA in the LD of pigs. Acetyl-CoA carboxylase enzyme gene was down-regulated in pigs fed 2:1 diet compared with finishing pigs fed the control or 4:1 diets. The relative expression of hormone-sensitive lipase was increased in pigs fed 2:1 and 4:1 ratio diets. Lower total cholesterol of plasma was observed in finishing pigs fed 2:1 and 4:1 diets. The cooking loss ratio of meat was lower in pigs fed the 2:1 and 4:1 diets compared with the control diet. Pigs fed the 4:1 and 2:1 diets had greater final body weight. In conclusion, the 2:1 and 4:1 diets have the potential to increase the meat quality and growth performance of pigs.

The status of health behaviors was surveyed in the random sample of 824 farmers (men 318, women 506) aged 40 years and older in Ulju-Gun, Kyungsangnam-Do. The data were collected by personal interview using structured questionnaire. The prevalence of individual health practices by sex(men/women) was 44.4%/45.0% in sleeping 7 or 8 hours; 92.7%/89.9% in eating breakfast almost every day; 82.7%/83.8% in eating between meals rarely or once in a while; 40.6%/88.1% in no drinking; 37.4%/86.6% in no smoking; 4.7%/5.6% in doing physical exercise regularly; 89.0%/80.0% in maintaining desirable weight for height (body mass index<25kg/$m^2$); 3.9%/23.2% in doing these health practices six or more The level of practicing health behaviors and perceiving their own health status was lower than the data from the residents in Pusan City. Therefore it could be expected to improve the health status of the residents in rural are through the effort to make them taking more interest in practicing health behaviors.

Genetic parameters for birth weights (BWT), calving ease scores observed from calves born by heifers (CEH), and calving ease scores observed from calves born by cows (CEC) were estimated using Bayesian methodology with Gibbs sampling in different threshold animal models. Data consisted of 77,458 records for calving ease scores and birth weights in Gelbvieh cattle. Gibbs samplers were used to obtain the parameters of interest for the categorical traits in two univariate threshold animal models, a bivariate threshold animal model, and a three-trait linear-threshold animal model. Samples of heritabilities and genetic correlations were calculated from the posterior means of dispersion parameters. In a univariate threshold animal model with CEH (model 1), the posterior means of heritabilities for calving ease was 0.35 for direct genetic effects and 0.18 for maternal genetic effects. In the other univariate threshold model with CEC (model 2), the posterior means of heritabilities of CEC was 0.28 for direct genetic effects and 0.18 for maternal genetic effects. In a bivariate threshold model with CEH and CEC (model 3), heritability estimates were similar to those in unvariate threshold models. In this model, genetic correlation between heifer calving ease and cow calving ease was 0.89 and 0.87 for direct genetic effect and maternal genetic effects, respectively. In a three-trait animal model, which contained two categorical traits (CEH and CEC) and one continuous trait (BWT) (model 4), heritability estimates of CEH and CEC for direct (maternal) genetic effects were 0.40 (0.23) and 0.23 (0.13), respectively. In this model, genetic correlation estimates between CEH and CEC were 0.89 and 0.66 for direct genetic effects and maternal effects, respectively. These estimates were greater than estimates between BWT and CEH (0.82 and 0.34) or BWT and CEC (0.85 and 0.26). This result indicates that CEH and CEC should be high correlated rather than estimates between calving ease and birth weight. Genetic correlation estimates between direct genetic effects and maternal effects were -0.29, -0.31 and 0.15 for BWT, CEH and CEC, respectively. Correlation for permanent environmental effects between BWT and CEC was -0.83 in model 4. This study can provide genetic evaluation for calving ease with other continuous traits jointly with assuming that calving ease from first calving was a same trait to calving ease from later parities calving. Further researches for reliability of dispersion parameters would be needed even if the more correlated traits would be concerned in the model, the higher reliability could be obtained, especially on threshold model with property that categorical traits have little information.
