The purpose of this study was to examine the status of environmentally-friendly ingredients and dietitians' perceptions toward them in order to find for improvement. Data was collected from questionnaires completed by 202 school dietitians and nutrition teachers in Chungbuk, and this data was analyzed utilizing the SPSS 20.0 program. The results obtained from this study were as follows: 'mixed grains (58.9%)' and 'eggs (36.6%)' were found to be the most used environmentally-friendly ingredients. 81.7% of the respondents said they 'never used' marine products, whereas 'fruits (43.6%)', 'pork (40.8%)', and 'fish (54.5%)' were the most preferred ingredients. Dietitians and nutrition teachers used environmentally-friendly marine products less than other ingredients, had a poor understanding about environmentally-friendly marine products, and demonstrated low reliability and belief in the necessity of the system. In order to verify the environmentally-friendly status of the ingredients, marks on the product and documents of certification were mostly used. In order to improve the supply system, a more strict tracking system in the distribution process by securing more reliable suppliers is required.

This paper shows alternative route search and preference route search for the traffic route search, and proposes the use of the fuzzy non-additive controller by the application of AHP(analytic hierarchy process). It is different from classical route search and notices thinking method of human. Appraisal element, weight of route is extracted from basic of the opinion gathering for the driving expert and example of route model was used for the finding of practice utility. Model evaluation was performed attribute membership function making of estimate element, estimate value setting, weight define by the AHP, non additive presentation of weight according to $\lambda$-fuzzy measure and Choquet fuzzy integral. Finally, alternative route search was possible to real time traffic route search for the well variable traffic environment, and preference route search showed reflection of traffic route search disposition for the driver individual. This paper has five important meaning. (1)The approach is similar to the driver's route selection decision process. (2)The approach is able to control of route appraisal criteria for the multiple attribute. (3)The approach makes subjective judgement objective by a non additive. (4)The approach shows dynamic route search for the alternative route search. (5)The approach is able to consider characteristics of individual drivers attributed for the preference route search.

XML can describe a wide range of data, from regular to irregular and from flat to deeply nested. Thus, XML is rapidly emerging as the do facto standard for the Web document format since XML supports an efficient data exchange and integration. Also, to retrieve the data represented by XML, several XML query languages are proposed. XML query languages such as XPath and XQuery use path expressions to traverse irregularly structured data which comprise B% elements. To evaluate path expressions, various path indexes are proposed. However, traditional path indexes are constructed by utilizing only the XML data structure. Therefore, in this paper, we propose an adaptive path index which utilizes the XML data structure as well as query workloads. To improve the query performance, the adaptive path index proposed by this paper manages the frequently used paths and the structural summary of the XML data using a hash tree and a graph structure. Experimental results show that the adaptive path index improves the query performance typically 2 to 69 times compared with the existing indexes.

Since no single routing-switching combination performs the best under various different types of applications, a flexible network is required to support a range of polices. This paper introduces an implementation of a look-up table routing engine offering flexible routing and switching polices without performance degradation unlike those based on microprocessors. By deciding contents of look-up tables, the engine can implement wormhole routing, virtual cut-through routing, and packet switching, as well as hybrid switching, under a variety of routing algorithms. Since the routing engine has a piplelined look-up table architecture, the routing delay is as small as one flit, and thus it can overlap multiple routing actions without performance degradation in comparison with hardwired routers dedicated to a specific policy. Because four pipeline stages do not induce a hazard, expensive forwarding logic is not required. The routing engine can accommodate four physical links with a time shared cut-through bus or single link with a cross-bar switch. It is implemented using Xilinx 4000 series FPGA.

Using hybrid channel affords the benefits of achieving control through the direct channel and achieving flexibility through the indirect channel. However, using a hybrid channel also poses special challenges to a manufacturer, including the problem of managing multiple channel members with disparate goals and priorities. The purpose of this study is to enhance our understanding on the management of hybrid channel. We study marketing channels for fashion apparel to examine governance challenges and solutions of a hybrid channel. We have two objectives to fulfill that purpose. First, we aim to tie two largely separate research streams of salesforce management and marketing channel management together by examining both intrafrim governance and interfirm governance issues under one conceptual framework. Second, we aim to lay a ground work for rigorous further research on this topic by tying two major theoretical approaches of governance together under one conceptual framework. Our predictions were tested with data from the survey of apparel manufacturers and retailers. The analysis results support the predictions moderately.

This study explores the issues of "eco-friendly consumption" through online media posts, and aims to identify changes in it. Total 6,812 blog posts on Naver, that included the words "eco-friendly consumption" and "eco-friendly lifestyle," published between 2005 and 2020, in five-year intervals, were analyzed. The results illustrated that consumption issues began with the identification of the causes of environmental problems however, "eco-friendly consumption" gradually gained importance, until it developed into preparing standards and alternatives for proper "eco-friendly consumption." In 2020, "eco-friendly consumption" values and ideal consumption practices were expanded into social movements. However, there is relatively little discussion on controlled and modest spending. Therefore, for the future direction of "eco-friendly consumption," it is necessary to thoroughly examine and highlight the agenda of controlled and modest living from a higher perspective.

웹 리소스에 대한 메타 데이타 표현을 위해 RDF가 표준안으로 제정됨에 따라 RDF 데이타 저장 및 질의 처리 등의 연구가 많이 진행되어 왔다. 전통적인 저장 시스템을 기반으로 하는 저장 구조는 단순한 트리플 패턴 기반의 질의 처리에는 효율적이다. 그러나 여러 개의 트리플 패턴들이 결합된 질의 즉, 경로 기반의 질의 처리는 많은 조인 연산이 요구된다. 한편, 경로 질의의 효율적인 처리를 위해 접미사 배열을 응용한 인덱싱 기법이 제안되었다. 그러나 이 연구에서는 부분 경로식을 포함한 단순 경로 기반 질의 처리의 성능이 향상됨을 보여주었으나 다양한 경로 질의 유형에 대한 처리는 고려하지 않았다. 본 논문에서는 접미사 배열을 응용한 인덱싱 기법을 기반으로 한 경로 기반의 RDF 질의 처리 방안을 기술 한다. 특히, 단순 경로 질의처리 이외에 다양한 질의 유형의 처리를 위한 방안들을 예제를 통해 설명한다.

본 논문에서는 내시경 영상에 대해 위암 영역을 자동으로 추출하는 방법을 제안한다. 본 논문에서는 내시경 영상을 획득하는 과정에서 발생하는 조명에 의한 잡음과 굴곡에 의해 발생하는 그림자에 의한 잡음 부분을 해결하기 위해서 HSI의 채도와 밝기 값을 이용하여 잡음 영역을 제거한다. 그리고 헤모글로빈 색소 정보를 나타내는 IHb값을 이용하여 전자 내시경 영상에서 유사한 헤모글로빈 색소 정보를 가지는 영역으로 분할한다. 분할된 영역들 중에서 RGB의 각 채널과 헤모글로빈 색소가 높게 나타나면 후보 영역으로 설정한다. 설정된 후보 영역 중에서 위암 영역의 형태학적인 특징 정보를 이용하여 위암 영역을 추출한다. 실제 전문의가 제공한 20개의 내시경 영상을 대상으로 실험한 결과, 제안된 위암 추출 방법으로 17개가 정확히 추출되었고 3개의 내시경 영상에서는 위암 영역이 정확히 추출되지 않았다.

경로 예측 기반의 센서 레지스트리 시스템(Path Prediction-based Sensor Registry System, PP-SRS)는 이기종 환경에서 센서 네트워크 환경에서 센서 데이터의 즉각적인 활용과 끊김 없는 해석을 위해 사용자에게 센서 정보를 제공한다. PP-SRS는 사용자의 위치를 경로 단편으로 사상하여 표현한다. 그리고 경로 단편기반으로 사용자의 경로를 예측한다. 그러나 도로 정보에 대한 경로 단편을 미리 구성해야 사용할 수 있으며 구성된 도로 정보를 무시한 경로가 발생하는 문제점을 가지고있다. 이 논문에서는 이 문제점을 해결하기 위하여 PP-SRS를 위한 격자를 이용한 개선방안을 제안한다. 이 논문은 기존의 경로 단편 표현방법과 제안하는 격자 기반 경로 표현방법에 대하여 비교한 후 PP-SRS에 개선 방법에 대하여 서술한다.
