Two phosphate solubilizing bacteria, Pantoea rodasii PSB-11and Enterobacter aerogenes PSB-12, were isolated from button mushroom compost and employed to assess their synergistic effect in liquid medium and on growth of green gram plants by single and co-inoculation of the strains. Co-inoculation of two strains was found to release the highest content of soluble phosphorus ($521{\mu}g\;ml^{-1}$) into the medium, followed by single inoculation of Pantoea strain ($485{\mu}g\;ml^{-1}$) and Enterobacter strain ($470{\mu}g\;ml^{-1}$). However, there was no significant difference between single inoculation of bacterial strain and co-inoculation of two bacterial strains in terms of phosphorous release. The highest pH reduction, organic acid production and glucose consumption was observed in the E. aerogenes PSB-12 single inoculated culture medium rather than those of co-inoculation. According to the plant growth promotion bioassay, co-inoculated mung bean seedlings recorded 10.6% and 10.7% higher shoot and root growth respectively compared to the control. Therefore, in concluding, co-inoculation of the strains P. rodasii and E. aerogenes displayed better performance in stimulating plant growth than inoculation of each strain alone. However, being short assessment period of the present study, we recommend in engaging further works under field conditions in order to test the suitability of the strains to be used as bio-inoculants.

In this study, based on the current curriculum of consumer education in high school with the advent of Web 2.0 age, I analyzed both the curriculum used by new information tools related with Web 2.0 age and the one used by traditional tools to find out the degree of necessity of consumer education for the high school students in proportion to the level of their informational ability. First, compared with the education of food, clothes and shelter in the curriculum of manual training and domestic science, the necessity, importance, and availability were low and the students had a lower level of interest than they had with the three factors mentioned above. Second, after dividing the sector of consumer education in the curriculum into three fields such as reasonable purchase and use, solution and prevention of consumer problems and forming a new consumer trend, I looked into the necessity of the teaching method using conventional tools and the one using new informational tools following Web 2.0 age respectively. Traditional tools were favored for the education of consumption-related laws and policies, consumers' rights for the general cause of consumer problem solving and preventing. For the generation of the new comsumer trend, the new information tools were preferred in the appreciation of consuming culture and the issues of consuming environment. Third, it was revealed that students' level of informational ethics was the highest at 5.55 while their level of information creation and processing was the lowest at 3.96 from the research of six categories of their informational ability.

The purpose of this research is to lay the foundation that middle aged woman takes care of more healthy, beautiful, attractive external features and prepares successful ageing on studying a difference of recognition between an actual somatotype and an ideal somatotype after we examine an actual somatotype and an ideal somatotype in the object of about $40{\sim}50$ middle-aged woman, dwells in Seoul, is the main group of a home consumption socially. The result of comparing a difference between an actual somatotype and an ideal somatotype was showing that in case of a facial form, the group which their faces are an egg-shaped prefers an egg-shaped and the group which their faces are a round-shaped prefers a round-shaped. In case of a silhouette, all groups prefers a normal type most. In case of a shoulder's type, all groups prefer a normal type most. In case of a shoulder-waist line, all groups prefers a Y line most. In case of a breast's form, all groups prefer a normal type most. In case of a back's form, all groups prefer a normal type most. In case of a buttocks' form, all groups prefers a normal type most. In case of a leg's form, all groups prefers a normal type most. On putting together research result as yet, middle aged women wish a similar somatotype irrespective of an age, an obesity measurement and this means a recognition of making an effort to be beautiful is alike. Therefore, it is necessary to recognize a somatotype of middle aged women uprightly and it must be accomplished a continuous, systematic consultation and education about a weight-control on exercising and not to mention of making a desirable eating habit.

The objectives of this study were to examine how the consciousness of resource saving affects the resource-saving behaviors of urban employed wives and to induce their rational resource-saving behaviors by identifying related variables. This study also analyzed some correlations between the resource-saving consciousness and behaviors of urban employed wives to provide basic information for laying the foundations of a green growth culture. The subjects of this study were selected from among employed wives living in the urban areas of Seoul and Gyeonggi-do area. The study was conducted from June 11 to August 7, 2011. A total of 620 questionnaires were collected, and 592 of them were used in the analysis. Data was analyzed via the SPSS 18.0 program to calculate frequencies, mean and standard variation, Cronbach's ${\alpha}$, t-test, ANOVA, Pearson's correlation, hierarchical, and multiple regression analysis. A positive correlation was observed between the resource-saving consciousness and behaviors of urban employed wives. That is, their resource-saving behavior was higher their consciousness of resource saving was high. Furthermore, the most influential variables affecting the resource-saving behaviors of urban employed wives were: the subjects' job type, with specialist or office work; reference groups, such as family, relatives, and neighbors; and low levels of conspicuous consumption habits. Among the variables, the influence of reference groups had the highest explanatory power.

본 논문은 무선 센서 네트워크의 계층형 라우팅 프로토콜 중 대표적인 알고리즘인 LEACH(Low Energy Adaptive Clustering Hierarchy)의 원거리 전송 시의 에너지 효율이 급감하는 현상을 개선하기 위하여 DL-LEACH(Dual-hop Layered LEACH) 프로토콜을 제안한다. 이는, 데이터 전송에 듀얼 홉(dual hop : 싱글 홉 + 멀티 홉) 방식을 도입하여 근거리 전송에서는 부분적 싱글 홉 방식을, 원거리 전송에는 클러스터 헤드 간의 멀티 홉 전송 방식을 도입하였다. 제안된 DL-LEACH는 듀얼 홉 전송 방식을 사용하여 원거리 전송의 경우에는 클러스터 헤드의 에너지 소모를 줄이고, 근거리 전송의 경우에는 전송 루틴을 단순화하고 전송 거리를 줄여 센서 노드의 에너지 효율을 증가시켰다. 그러므로 일반적인 LEACH에 비교하여 넓은 센서 필드에 적합하다. 제안된 방법을 시뮬레이션을 통하여 검증하였다.

광고는 변화하는 사회를 가장 빠르게 반영하는 매체 중 하나이며, 전 지구화와 소비문화가 일상 속으로 확산되는 것과 밀접한 관계를 갖고 있다. 이 논문은 현재 한국에서 다문화주의란 어떤 의미이며, 변화하는 사회의 모습이 광고에 어떻게 나타나고 있는지에 대한 고찰이다. 특히 최근 한국인 이외의 다양한 인종과 민족이 영상 광고에서 어떤 식으로 재현되었는지 살펴봄으로써, 다문화주의의 의미가 구성되는 방식을 살펴본다. 우선 한국의 다문화주의의 역사적 배경과 의미를 외국의 경우와 비교해서 살펴보고, 다문화주의와 인종주의 사이의 관계를 이론적으로 밝힌다. 이어서 정보/통신, 아파트, 금융 광고 등 전 지구화 시대에 다문화주의 전략을 가장 적극적으로 채택하고 있는 상품 광고를 중심으로 구체적 분석을 실시한다. 분석 결과 다문화적인 방식으로 재현된 광고들이 오히려 기존의 인종주의를 강화하거나 한국(인)이 중심이 된 민족주의의 정서를 강화하는 것으로 나타났다. 다문화적인 요소를 담아낸 광고가 양적으로 크게 증가했음에도 불구하고, 한국사회의 '다문화주의'는 여전히 전략적인 수준에 머물고 있는 것으로 보인다.

It is very important that the development of rural tourism resources and contents for agritourism increases rural household income and vitalizes local economy. In this sense, accelerating the rural traditional food materials into resources plays significant roles for the local economy. The farm-restaurant project, as a part of a development of rural traditional foods can not only help popularize the rural food-culture, but it also promote the consumption of local products by urban customers. It is difficult to manage both types of restaurants which are the dining type and the experience-centered farm restaurants as a farmer. In particular, the managers of the farm restaurants have some operational problems in developing a new menu and an experiential-program using their local farm products. The purpose of this study was to present steps that can be used for the existing menu-improvement and developing new menu processes of the farm restaurants that have been in operation for more than two years. By the purpose of menu developing for a restaurant, this research is designed for the case study. For collecting date for the study, we gained knowledge about the issues concerning menus from in depth interviews with the managers in two subject farm restaurants. The results suggested that a new menu, such as table d'h$\^{o}$te, $\`{a}$ la carte meals, specialties, kids meal, various dressing, are based on solving issues such as a limitation of food materials and the necessity of a kids meal in dining type of farm restaurants. Also, the suggested new menu, such as seasonal specialties and side dishes, are based on solving issues such as urgent development of various experiential programs and necessity of seasonal specialties in experiential type of farm restaurants.
