광주시 관내 폐수배출시설 방류수 6지점과 대형 건축물 오수 처리시설 방류수 4지점 및 중수 처리 재이용수, 건물 옹벽 지하수 2지점의 수질을 분석하여 중수로써 재이용 가능 여부를 조사한 결과 폐수 배출시설 방류수의 경우 조립금속제품 제조시설, 축전지제조시설 및 타이어제조시설이 대체적으로 중수도의 수질기준을 만족하고 있어 현재의 방류수를 그대로 중수로 이용 가능하리라 판단된다. 오수 처리시설 방류수의 경우 4지점 모두 유기물질은 물론 색도, 탁도 등 대부분의 항목이 중수도 수질기준을 초과하여 현재의 방류수 자체를 중수로 사용하기는 불가능 할 것으로 판단되며, 이들 방류수를 중수로 재이용하고자 한다면 모래 여과조나 활성탄 여과조, 소독시설 등 중수 처리시설을 설치하여야 할 것으로 판단된다. 오수처리시설 방류수를 중수 처리하여 재이용 하고 있는 중수의 경우 대부분 중수도의 수질기준을 만족하였으나, 색도와 탁도, 대장균군의 경우 일부 상당히 불안정한 수질을 보였으나 현재 화장실 세정수로 이용하고 있는데 색도 외에는 별다른 문제가 없는 것으로 나타났고, 대형빌딩 옹벽에서 흘러나오는 지하수의 경우 일반세균과 질산성 질소를 제외하고는 모두 먹는물 수질기준에 적합한 것으로 나타나 현재의 지하수를 그대로 청소용수나 화장실 세정수 등의 중수로 재활용해도 충분하다고 판단되며, 활성탄 여과조와 소독 시설 등의 추가시설을 갖춘다면 먹는 물로도 사용이 가능하리라 보며, 수량적인 측면에서도 1일 발생량이 100~400톤 이상이므로 충분히 경제성이 있을 것으로 판단된다.

대형시스템의 배터리 관리 시스템은 일반적인 운영체제(Operation System)나 실시간 운영체제(Real Time Operation System)를 사용하여 배터리 관리 시스템을 하는 반면 휴대용 전자정보기기와 같은 소형시스템에서는 유한상태머신(Finite State Machine)을 이용한 배터리 관리 시스템을 사용한다. 이러한 대형시스템은 대부분 고성능을 요구하기 때문에 시스템을 유지하기 위해서는 막대한 비용이 들어간다. 이 결과로 상업적 제품의 가격적인 장점을 위하여 특화된 기능만을 지원하는 유한상태머신을 사용하는 배터리 관리 시스템을 많이 이용하고 있다. 최근에는 멀티미디어 기록 및 재생의 많은 전력소모를 요구하는 모바일 시스템이 많아지므로 콘텐츠 기반 배터리 관리 시스템 등 복잡한 배터리 관리 시스템을 소형기기에 적용하기 위하여 많은 연구가 진행되고 있다. 운영체제를 기반으로 하는 배터리 관리 시스템은 모바일 시스템에 사용하기에는 자체 전력소비가 많으며, 유한상태머신을 사용하는 배터리 관리 시스템은 다양한 요구와 복잡한 배터리 관리 시스템의 기능을 수용할 수 없다. 본 논문에서는 상기 두 가지 경우의 장점을 취한 이벤트 드리븐 프로그래밍(Event-Driven Programming) 방식을 사용하여 배터리 관리 시스템을 제안하고 제안된 시스템이 SBS(Smart Battery Data Specification v1.1)[1]를 만족할 수 있음을 보였다.

According to the lack of specific research on small business, this study analyzed the effects of a limited edition marketing strategy in a small business, whereas many previous studies focused only on large businesses. The test was performed by releasing and selling a limited edition (LE) product of a small brand with annual sales of about $10,000, for a limited time (one week), alongside social network advertising on Instagram. As this strategy resulted in a 10 times increase in sales from the previous year, the author concluded that a limited edition marketing campaign can significantly improve brand awareness and increase sales in a small independent business as well as larger businesses.

Abundance and composition of marine debris on 13 beaches of Tongyeong City, South Korea were surveyed in 2013 Autumn. The average quantity of macro debris (>25 mm) was about 30 particle/$m^2$ and that of micro debris (1 mm-25 mm) was about 26,971 particle/$m^2$. This is a very high level compared with other areas of South Korea and the other countries. Among the 7 material types of debris (styrofoam, hard plastic, fiber, metal, glass, wood and others), styrofoam composed a large portion: 75% of macro debris and 98% of micro debris. And among the 'whole' styrofoam debris items whose original volume is remained more than 50%, styrofoam buoy debris composed 93%. This result suggests that the beaches surveyed are seriously contaminated by marine debris, and most of its sources are aquaculture styrofoam buoys. Management of styrofoam buoy debris used for oyster aquaculture in Tongyeong City is important not only for Tongyeong city, but also for other areas, because Tongyeong city hosts the biggest number of oyster aquaculture areas in South Korea.

As the recently advanced scientific developments result in high lever of the usability and the needs for the electrical equipment and devices in various situations, the safety technologies protecting malfunction and electrical critical damages including soft and hardware from the unexpectedly radiated electromagnetic interferences are required gradually. In addition, the numerical analysis for the miniaturized electrical components and equipments as well as the conventional electrical devices installed inside the electrically large enclosures and structures requires the memory requirement and time consumption too big to be handled in a realistic situation, which will result in a limitation in solving the complete set of maxwell's equations. In this paper, PWB method based on statistical theory and topological modeling with appropriate zoning concepts are introduced for the EM analysis of an electrically large complex structures.

왜 자판기 커피가 못 마실 음료처럼 비난을 받아야 하죠? 일부 미니 커피자판기에 사용된 원료 문제를 마치 전체 자판기 문제인 냥 떠들어 때는 매스컴이 정말 원망스럽습니다. -자판기 운영업자 K씨- A급 원료를 쓰고 있는데도 불구하고 마치 죄인 마냥 '멜라민 커피프림을 쓰지 않는다'는 해명문구를 써서 부쳐야 하니 정말 열불이 나더군요." -자판기 운영업자 P씨- 올 가을은 그야말로 중국산 멜라민 파동이 식품 업계 전반이 휘몰아친 한해였다. 해태제과의 '미사랑 카스타드'로 불붙은 멜라민 파동은 제작 전반을 걸쳐 자판기 커피프림 분야로도 불똥이 튀었다. 식품의약품안전청은 중국산 커피프림 원료를 수입하는 3개 업체의 10개 제품을 조사한 결과, 유창FC의 '베지터블 크림 파우더 F25에서 멜라민 1.5ppm이 나왔다'고 밝혔다. 이 크림은 41톤이 수입되어 25톤이 시중에 팔려나갔으며, 주로 자동판매기용 믹스커피나 커피전문점에 사용한 것으로 보도가 되어 일파만파로 파문이 확산되었다. 대부분의 매스컴 보도는 '자판기 커피프림에 멜라민이 들어갔고, 그래서 마셔서는 안 된다'는 식으로 과당보도가 되다 보니 소비자들의 분노의 불신이 걷잡을 수 없이 커졌다. 이에 자판기 커피 매출을 뚝 떨어 졌고, 그 동안 애용했던 자판기 커피에 등을 돌리는 사람들이 많아 졌다. 마치 자판기 커피가 식품안전을 위협하는 원흉이나 되는 듯한 분위기였다. 그런데 이런 뜻하지 않은 악재가 자판기 업계로 보면 억울하기 그지없는 일이다. 이번에 문제가 된 것은 식당 등에 설치된 '미니 커피자판기' 일부에 해당되는데도 불구하고 매스컴 보도는 전체 자판기가 문제가 된다는 식이었다. 대다수의 매스컴이 미니 커피자판기와 대형 커피자판기를 구분하는 개념도 없다보니 문제가 없는 대형 자판기를 불똥이 튈 수밖에 없었다. 또한 미니 커피자판기에서 그런 원료가 투출되기 쉬운 열악한 사업특성에 대해서도 언급을 하지 않았다. 일부분의 문제를 '침소봉대'하여 전체의 문제인 것처럼 보도하는 매스컴의 무책임한 태도가 가뜩이나 어려운 자판기 산업계에 직격탄을 날렸다. 대다수의 자판기, 특히 대형자판기들은 억울하기 그지없는 일이다. 이번 커피자판기 멜라민 사태를 통해 과연 매스컴 보도가 무엇이 잘못되었고, 산업계에 어떠한 과제를 내던졌는지를 심층 진단했다.

The entry of large discount stores such as LG-mart, E-mart into small cities such as Choonchun or Wonju have had a profound impact on the business of small-sized retailers. The impact of the entry by large discount store is too big compared to that of the entry by department store. Now, it becomes the matter of survival for small-sized retailers. Regulation and protection are not the best solutions to solve these problems. It cannot solve the fundamental problems. Consumer buy products based on their needs not retailers' problems. Without satisfying consumers' various needs and wants, retailers can not survive. Therefore, it is extremely important to understand retail competition from the perspective of consumers and investigate overall retail competition not competition between two different types of retailers. In this study, we analyze the relationship between products and purchasing places, the competitive relationship among retailers. As a result, we get big picture of retail market and discuss the revitalization of conventional retailers. In addition, we propose new solutions to conventional retailers' problems from the perspective of consumers.

The purpose of this study was to investigate the use and perception of adults concerning bokbunja (Rubus coreanus Miquel) products. Self-administered questionnaires were collected from 502 residents in the Daegu and Gyeongbuk area. According to the survey more females in their 20s responded than males (45.2 and 54.8%, respectively). In total, 82.6% of respondents had an income of under 4,000,000 won per month and most were living in the city. The results regarding knowledge about bokbunja products showed that the bokbunja wine score was highest (3.66), and intake frequency showed that over half of the respondents had never eaten bokbunja products. The preference for bokbunja wine by males was higher than that for females, whereas the others products showed higher scores for females than for males. When asked about how they knew about bokbunja products, 37.0% of males and 46.9% of females responded a family member or neighbor. When purchasing bokbunja products, males and females answered that they considered taste, country of origin, and manufacturer, and price. Approximately 48% of the respondents answered that they purchased bokbunja products in the grocery and department store. As a result, popularization of bokbunja products was based on product development and sales promotion, and the product development factor significantly influenced preference for bokbunja products.
