Purpose: This study seeks to develop behavior-induced automatic separation X-Bin for disposable cup speculators. Some students throw away the contents. Research design, data and methodology: Therefore, environmental beautification workers spend a lot of time sorting disposable cups at school garbage collection sites. Disposable cups that have been thrown away like this are bad in terms of appearance and smell. In addition, cleaning inside garbage affects recycling rates and is closely related to environmental problems. Results: Clean cleaning reduces the amount of garbage incinerated without being recycled and reduces the cost of recycling. According to Korean Social Trends 2020, COVID-19 began to spread, and recycling of disposable items such as disposable cups increased by about 15 percent from the same period last year. Conclusions: These are classified for recycling, and the amount of garbage thrown on the streets is estimated to be larger. In order to prevent COVID-19s, the use of disposable goods is inevitable, but facilities are needed to dispose of them properly.

This article deal with an overview of food waste treatment methods in Korea. Garbage trucks are operated manually by garbage workers who pick up the food wastes after food waste is placed in plastic bags by the road sides. However, there are a lot of problems such as, the smell from the split bags and the leachate, the loss of much energy and the complaints regarding the establishment new rubbish tips from the residents in the surrounding area. It also highlights our society's waste of resources. Although the new pneumatic waste transfer system or the dry method seem to have improved some of the environmental conditions, it still bears some problems, for example, the lack of reuse and recycling of resources and the economic problems. We have been analysed the advantages and disadvantages between the existing food waste system and the pneumatic waste transfer system. And the dry method and disposer were discussed. The results will indicate how the disposer can improve more than the existing systems and will provide the evidence to support.

The purpose of this study was to investigate the environmental awareness and attitude of elementary school teachers. For this study, 100 elementary school teachers from H graduate school of education were sampled. The results of this study were summarized as follows. First, the biggest concern of environmental problems were water-pollution and garbage problems by the lack of understanding about the environment and injudicious development. Second, most teachers recognized the need for environmental education and they answered that they were doing best to teach students with the main purpose of helping them develop values of environmental preservation. Third, most environmental education was carried out during class using current events and the emphasis on garbage separation and recycling. They also showed the lack of teaching materials and field trips for environmental education. Fourth, it appeared to come from media-oriented environmental education. Most teachers mainly used newspapers and visual materials. 1'hey were obtaining knowledge and information related to environmental education through the media. Since in-service teachers' conceptions could directly effect present education, it is necessary to establish a more systematic educational system for environmental education, for in-service elementary school teachers.

현대사회의 도시화 추세가 지속됨에 따라 인구의 집중으로 주거환경에 대한 도시문제의 중요성이 대두되고 있다. 다양한 도시문제 중에서 대표적인 문제 중 하나는 쓰레기 문제로 시민들의 주거환경 악화의 원인이 되며 시정 만족도에 대해 직접적으로 영향을 미치는 요인이다. 이와 같은 쓰레기 문제는 단순히 주거지역의 쓰레기 배출량에 대한 분석으로는 정확히 예측할 수 없으며 쓰레기의 주거지역에 분포하고 있는 거주민의 생활양식과 특징에 대한 분석이 필요하다. 본 연구에서는 주거지역 내의 거주민의 분포에 따라 발생할 수 있는 쓰레기 문제와 이에 대한 만족도 분석을 수행하기 위하여 이산사건 시스템 형식론을 활용한 에이전트 기반 거주민 모델링과 시뮬레이션 환경을 제안한다. 제안하는 연구는 주거민의 시계열적인 특성을 표현하기 위하여 원자모델을 사용하였으며 시뮬레이션 모델의 재사용성을 증대시키기 위한 결합모델을 사용하여 다가구와 다가구 주택을 모의하였다. 또한, 본 연구는 다가구 주택지역에 대한 시뮬레이션 모델링을 진행하고, 시뮬레이션을 수행하였다. 연구결과로 다가구 주택지역의 시뮬레이션에서는 거주민의 특성을 고려한 결과와 그렇지 않은 결과 사이에 뚜렷한 차이점을 발견할 수 있었으며 지역 문화적 특성과 시간적 특성을 고려한 시뮬레이션이 필요함을 확인할 수 있었다.

A community-centered smart village process model was developed through the theoretical review of the rural field forum. By analyzing the difference in technology demand according to the digital capabilities of leaders by community type, village types were classified and detailed technologies were defined. The smart village process was proposed to enable residents to operate autonomously by inducing continuous interest and participation of local residents through the conception stage, planning stage, implementation and self-reliance stage, and allowing them to cooperate together. The business model canvas was reconstructed to be used in the workshop. It was applied to the village of Yesan-gun. As a result of running a resident workshop using the business model Cambus, the lack of resident awareness and illegal garbage dumping were presented as the first problems to be solved. The value of the village was set as 'a village that is clean and clean with a sense of residents, and a good place to live', and users were expressed as 'family' and 'outsiders'. It was suggested that we meet frequently to convey the value of the village by using broadcasting and announcements as a channel to convey the value. Core activities were to cultivate residents' consciousness, such as implementing a campaign against illegal garbage dumping, and to establish and guide separate collection sites. When a garbage collection center is installed, it was estimated that around 2 million won per month for management costs, and it was investigated that it was possible to spend an hour or so twice a month to solve the problem of illegal dumping. If a method to derive village projects based on the derived business model canvas is developed in the future, it will be more practical.

An application of case-based reasoning is proposed to build an influence diagram for identifying successful new ventures. The decision to invest in new ventures in characterized by incomplete information and uncertainty, where some measures of firm performance are quantitative, while some others are substituted by qualitative indicators. Influence diagrams are used as a model for representing investment decision problems based on incomplete and uncertain information from a variety of sources. The building of influence diagrams needs much time and efforts and the resulting model such as a decision model is applicable to only one specific problem. However, some prior knowledge from the experience to build decision model can be utilized to resolve other similar decision problems. The basic idea of case-based reasoning is that humans reuse the problem solving experience to solve a new decision. In this paper, we suggest a case-based reasoning approach to build an influence diagram for the class of investment decision problems. This is composed of a retrieval procedure and an adaptation procedure. The retrieval procedure use two suggested measures, the fitting ratio and the garbage ratio. An adaptation procedure is based on a decision-analytic knowledge and decision participants knowledge. Each step of procedure is explained step by step, and it is applied to the investment decision problem in new ventures.

Flash memory adoption in the mobile devices is increasing or vanous multimedia services such as audio, videos, and games. Although the traditional research issues such as out-place update, garbage collection, and wear-leveling are important, the performance, memory usage, and fast mount issues of flash memory file system are becoming much more important than ever because flash memory capacity is rapidly increasing. In this paper, we address the problems of the existing log-based flash memory file systems analytically and propose an efficient log-based file system, which produces higher performance, less memory usage and mount time than the existing log-based file systems. Our ideas are applied to a well-known log-based flash memory file system (YAFFS2) and the performance tests are conducted by comparing our prototype with YAFFS2. The experimental results show that our prototype achieves higher performance, less system memory usage, and faster mounting than YAFFS2, which is better than JFFS2.
