  • 그리드 컴퓨팅에서는 자원의 상세 정보를 실시간으로 사용하기 어렵기 때문에 자원 관리와 할당이 기존 시스템에 비해 비효율적이다. 따라서, 본 논문에서는 작업의 총 실행시간을 예측하여 그리드 자원을 할당하는 새로운 스케줄링 정책을 제안한다. 이 스케줄링 정책의 특징은 원격 스케줄러와 로컬스케줄러를 사용하여 2단계 스케줄링을 수행한다. 원격 스케줄러에서는 자원 데이터베이스에 저장된 네트워크 환경과 로컬시스템의 정보를 사용하여 작업의 총 실행시간을 예측한다. 그리고 총 실행시간이 최소인 로컬시스템에 작업을 할당한다. 로컬스케줄러에서는 할당된 작업의 대기시간과 처리시간을 계산한 후, 작업을 데드라인 내에 처 리 할 수 있다면 로컬 시스템에서 처리한다. 하지만 데드라인을 초과하면 다른 로컬시스템으로 이주시켜 처리함으로써 작업실패율(failure rate)과 자원비용(resource cost)을 최소화한다.

  • 로컬 히스토그램 평활화(LHE)는 영상에서 로컬 정보를 강조하기 위한 효율적인 알고리즘 중 하나이다. 그러나 이 알고리즘은 스펙클 노이즈를 증폭시키는 단점을 가진다. 따라서, 기존의 로컬 히스토그램 평활화 기법을 확장한 다중 레이어 블록 오버랩 히스토그램 평활화 기법을 이용하여 기존 로컬 히스토그램 평활화 기법들의 문제점을 해결하고자 하였다. 이 방법은 3단계-컨트라스트 향상 단계, 노이즈 제거 단계, 통합 단계로 이루어진다. 제안된 방법에서는 기존 방법의 컨트라스트 향상 단계에서 일반적인 로컬 히스토그램 평활화 방법이 아닌 컨트라스트를 제한하는 적응적인 히스토그램 평활화 기법을 적용하고, 노이즈 제거 단계에서 새로운 바이레터럴 필터를 적용하였다. 즉, 기존 방법의 문제점들을 해결하도록 알고리즘을 변형하여 기존 알고리즘의 성능을 개선하였다. 실험 결과는 제안된 방법이 기존의 방법 및 잘 알려진 로컬 히스토그램 평활화 기법들과 비교하여 좋은 성능을 내는 것을 확인하였다.

  • Local food industry has been spreading all over the world. Korea is also actively applying and developing local food industry. However, relatively high distribution cost in Korean agricultural market is hindering its further growth. Distribution cost has close relation with shipping distance. Raised distribution cost brings major impacts not only on quality and price of products but also on greenhouse gas(carbon dioxide) emissions. Therefore, it is necessary to find a solution for inefficient distribution system of the local food industry to reduce overall cost and greenhouse gas. In this study, we present a location selection model for local food regional center using Analytic Hierarchy Process. The location of local food regional hub center is decided based on expert opinions on five factors: accessibility, quality, population, size of area, and shipping distance. The relative importance of the five factors has been concluded as follows: quality (0.430) ${\gg}$ population (0.262) ${\gg}$ travel distance (0.201) ${\gg}$ accessibility (0.075) ${\gg}$ and area (0.033). We apply and analyze the environmental management system model for Local food industry to develop the regional hub center site selection criteria and to analyze the effects of greenhouse gas emissions in the local food industry. This study, by applying and analyzing the environmental management system of the local food industry, is believed to be a valuable asset for managing greenhouse gas emission in the local food industry. Also, the data will be used for the autonomous local food industry's direct sales stall management. Eventually, this study will contribute so greatly to the local food industry's competitiveness that even large distribution companies will give way for the local food industry.

  • The purpose of this study was to conduct an empirical survey on consumer perception and consumption behavior in relation to local food and eco-friendly food. The survey was conducted using 266 consumers who have heard about or purchased local foods and eco-friendly foods centering on Seoul and Gyeonggi-do, and statistical analysis was carried out using SPSS (Version 23.0) to generate descriptive statistical values such as frequency and percentage and implement a Chi-square test. The results showed that consumers purchased local food in large shopping malls, supermarkets, and local food stores, whereas eco-friendly food were usually bought in large shopping malls, supermarkets, and eco-friendly food specialty stores. For local food, consumers bought fruits the most, followed by vegetables, whereas for eco-friendly food, consumers purchased vegetables the most, followed by fruits. The top reason for purchasing local food was its "fresh and high quality," whereas the top reason for buying eco-friendly food was "safety from pesticides and additives." According to results of the Chi-square test, women, unmarried people and younger people turned out to have more experiences in purchasing local foods and eco-friendly foods compared to men, married people and older people, respectively. Although local and eco-friendly food were completely different concepts, results of the study show that consumers were not able to make a clear distinction between the two. Consumer education, therefore, should involve defining the two types of food and spreading awareness on local and organic food to help them made the right choices when buying food.

  • The purpose of this study is to suggest new methodologies for documenting locality in digital environment, reformulation the Cox's documentation model focused on cooperative acquisition of documentary heritage institutions. This study defines the concepts of locality, space and place, relation of collective memory to archives, and analyzes the four approaches of documentation comparatively. Based on these analyses, it suggests the categories of documenting locality, and the directions of archive portal design for collective memory of locality.

  • 개체단위 감정분석(Aspect-Based Sentiment Analysis)는 자연어 처리에서 중요한 연구분야이다. 이는 입력 문장중에 존재하는 aspect term 의 감정 극성을 분석하는 것이 목적이다. 이 분야에서 현재 많이 사용되는 모델은 대부분 로컬 텍스트 또는 로컬 덱스트와 aspect term 사이의 관계에 주목하고 있다. 로켈 텍스트에 비해 글로벌 텍스트는 로컬 텍스트 뒤에 aspect term 내용을 추가해서 문장중에 있는 aspect term 내용을 더 깊게 학습할 수 있다고 생각한다. 본 논문에서는 새로운 masked attention 메커니즘을 사용하고 attention 메커니즘의 입력으로 글로벌 텍스트중에 있는 로컬 텍스트를 가로채어 전체 글로벌 텍스트의 내용과 융합한다. 이 방법은 semeval2014 데이터 셋에서 매우 좋은 결과를 얻었다.

  • This paper addresses issues to efficiently collect and aggregate data of sources within a local and adjacent region in geographic routing for wireless sensor networks. We first introduce the concept of a local sink which collects and aggregates data form source nodes in the region and delivers the aggregated data to a global sink. We also design a model to determine an optimal location of the local sink and propose a mechanism to collect data through the local sink. Simulation results show that the proposed mechanism with the local sink is more efficient in terms of the energy and the data delivery ratio than the existing mechanism without the local sink in a geographic routing.

  • This study was conducted in Tateyama, Japan with on-site observation conducted by Professor Aizawa, who organized this locality movement. This research was focused on listening to people's explanations, observations and studying the related documentation. First of all, the locality of Tateyama City was formed by utilizing the historic records of the area. Through Namo Amitabha which was carved on the four-sided stone pagoda, the city formed the locality as the peaceful city. "The gift of the Sea" painted by Shigeru Aoki in this city contributed to the identity of this locality known as the 'city of art which the painter loved'. The reconstruction of localities through the documentation of the relics are as follows. Satomi Castle, which was discovered to be the setting of the famous fictional saga Satomi and the Eight "Dogs". The excavation and research of the ruins of forgotten World War II, is another example of reconstruction at this locality. This locality is seen as 'the city of peace' and was reconstructed through a positive and future oriented attitude. It is noticeable that the locality of Tateyama city was newly formed or reconstructed using local records and documentation relics in the area.

  • The purpose of this paper is illuminating positively the perception and compliance rate of local food principles in Korea. The results are as follows. First, in terms of the perception rate, social trust and local production/consumption are the most important components rather than eco-friendliness. This means the importance of both spatial and social aspects of local food concept. Second, in terms of the compliance rate, social trust and shortened food chain are well complied, rather than eco-friendliness and shortened food miles. Third, in terms of the difference between perception and compliance rate, the social aspects such as eco-friendliness, social trust, and shortened food chain has shown relatively smaller difference than the spatial aspects such as shortened food miles and local production/consumption.
