This study aims to examine consumers' trust and purchase intention in environment-friendly agricultural products and factors influencing purchase intention degree of environment-friendly agricultural products. In addition, it aims to help seek national health promotion methods through purchase of consumers' environment-friendly agricultural products by providing the government, businesses, consumer organizations, etc. with basic data on them. The survey was performed for 2 months from August 1, 2012 to September 30, 2012, and a total of 350 questionnaires were distributed and 321(91.7%) copies out of them were used as final analysis data. The results of the study are as follows. First, the analysis of the effects of environment-friendly consumption value on trust in environment-friendly agricultural products showed that all the independent variables including environmental conservation value and economic value had a significant influence on trust in environment-friendly agricultural products, and economic value among them was the most influential item. Second, the analysis of the effects of environment-friendly consumption value on purchase intention for environment-friendly agricultural products showed that all the independent variables including environmental conservation value and economic value had a significant influence on purchase intention for environment-friendly agricultural products, and economic value was the most influential item. Third, the analysis of the effects of trust in environment-friendly agricultural products on purchase intention for environment-friendly agricultural products showed that as trust in environment-friendly agricultural products gets higher, consumers' purchase intention for them increased.

Routing paths are mightily important for the network security in WSNs. To maintain such routing paths, sustained path re-selection and path management are needed. Region segmentation based path selection method (RSPSM) provides a path selection method that a sensor network is divided into several subregions, so that the regional path selection and path management are available. Therefore, RSPSM can reduce energy consumption when the path re-selection process is executed. However, it is hard to guarantee optimized secure routing path at all times since the information using the path re-selection process is limited in scope. In this paper, we propose partial path selection method in each subregion using preselected partial paths made by RSPSM for routing path optimization in SEF based sensor networks. In the proposed method, the base station collects the information of the all partial paths from every subregion and then, evaluates all the candidates that can be the optimized routing path for each node using a evaluation function. After the evaluation process is done, the result is sent to each super DN using the global routing path information (GPI) message. Thus, each super DN provides the optimized secure routing paths using the GPI. We show the effectiveness of the proposed method via the simulation results. We expect that our method can be useful for the improvement of RSPSM.

몇 년 전부터 아파트 분양 광고에서 빠지지 않고 등장하는 것 중 하나가 '친환경' 또는 '웰빙'이란 단어다. 단지 입지에서부터 시공, 마감재까지 어김없이 친환경이란 용어가 등장한다. 하지만 시공 과정에서 멋을 내는 장식 정도로만 쓰이는 것이 국내 친환경 주거 단지의 현실이다. 콘크리트 시공이 필요한 차도나 보도를 최소화하고 단지 내 쾌적성을 우선시하는 유럽의 대표적인 친환경 주거 단지를 찾아가보자

This study was carried out to analyze factors influencing Korean consumers' attitude and buying behavior on the green products. The research model was constructed that values and personality variables affect on attitudes and the attitudes affect on buying behavior. Variables in the model were selected altruism and collectivism values, dominance and tolerance as personality. The results show that altruism, collectivism and tolerance have significant positive influence on the attitudes, but dominance has not. Attitudes on the green products connect to buying them positively. When consumers buy green products, a high price factor and distrust about the benefits of green products were investigated the largest concerns. We emphasize it is important based on the results of this study that green marketing should focus on social values, find consumer benefits and use trusty ways to communicate with consumers. Also, we need leadership and self-respect based on altruism and collectivism for the sustain ability of our society.

When the movement of a node breaks the route in ad-hoc network, on-demand routing protocol performs the local route recovery or a new route search for the route maintenance. And when it performs the new route search or the local search, the packet which is transmitted can be delayed. There are ARMP and RPAODV as the methods reducing the delay resulted from the route-breakage. They predict the route-breakage and construct an alterative local route before the occurrence of the route-breakage. When the link state is unstable, the success rate of the alternative local route that can avoid the route-breakage can give a direct effect on the route-breakage and the transmission delay, To estimate the performance of routing protocols avoiding route-breakage, we suggest the numerical formulas of AODV, the representative on-demand routing protocol, and ARMP, RPAODV. To verify the efficiency and accuracy of the proposed numerical formulas, we analysis and compare with the results of the computer simulation and that of the numerical formulas.

Endoscopic resection has been established as one of the treatment options for selected cases of early gastric cancer in Korea. Yet the indications, best treatment methods, management of complications and follow-up methods after the procedure are still uncertain. Some large-scale multicenter studies have recently been reported in Korea. In this review, I will provide an overview of the recent published articles and future directions for endoscopic resection of early gastric cancer.

경편성 분야는 생산 특성상 소재 원사가 균제하고 강도가 높아야 하므로 주로 사용할 수 있는 원사가 폴리에스테르, 나일론 등의 합섬 필라멘트사에만 주로 한정되어, 새로운 소재를 찾기 위해 노력 해왔다. 그러므로 경편성은 PTT 원사를 대량으로 소비할 수 있는 잠재적인 가장 큰 시장이다. 그러나 PTT를 경편성의 소재로 사용하여 새로운 수요를 창출하기 위해서는 PTT 경편성물과 기존 합성 필라멘트를 소재로 한 경편성물의 물성과 태의 차이가 우선 파악되어야 하며, 정경, 편성 및 형태안정 과정(relaxation)에 관한 연구도 진행하여 새로운 소재에 알맞은 공정 조건이 설정되도록 해야 한다.

척추경 나사못을 이용한 요추 유합술은 가장 보편적으로 사용되어지는 수술적 치료 방법이다. 과거 여러 연구들에서 이러한 척추 유합술의 임상적 우수성은 이미 입증 되었으며, 척추경 나사못은 시술 부위의 운동을 완전히 제한함으로써 높은 유합율을 얻을 수 있으나, 상대적으로 인접 분절의 조기 퇴행성 변화의 요인 중 하나로 보고되고 있다. 따라서 본 연구에서는 유한요소해석 방법을 이용하여 척추경 나사못 시술에 따른 척추체의 운동범위 및 인접 분절 추간판의 스트레스 증가량을 계산하였고, 척추경 나사못 모델과 유합 후 나사못 제거에 따른 모델 또 시술하기 전 정상모델과 비교하여 생체 역학적 측면에서 분석하여 척추경 나사못을 이용한 요추 유합술 후, 척추경 나사못의 제거의 임상적 효과와 그 이론적 근거를 제시하고자 한다.
