Waste office paper, photocopied or laser printed, has recently increased along with office automatization. In waste office paper, toner ink is used as the printing medium in place of conventional oil ink. Since toner ink cannot be saponificated by alkali and be decolored by bleaching, different from the case of oil ink, toner remains on regenerated paper as black specks. Although cascade recycling of waste office paper is compelled at present, the demand for low-grade paper is limited. From such circumstances, a new separation process for waste office paper is demanded to achieve parallel recycling. At the first stage of separation studies, the sharpness of separation is evaluated using small separators to obtain fundamental data. In a lab-scale separator, the sample amount of one feed is generally a few grams. However, the sample amount used for brightness, ERIC, and image analysis that are generally used to evaluate the efficiency of deinking are not small for lab-scale tests of these analyses. This paper describes an investigation of a sheet preparation method by a small amount of sample under 0.5g and compares the precision of toner content determination of spectroscopic analysis and image analysis from the viewpoint of separation evaluation. The easiness and convenience of the operation using only general-purpose equipments has also been set as a principle purpose. From the viewpoint of an analysis that yields high precision with a small amount of sample in short time, the method calculating the absorption coefficient from diffuse reflectance in the visible region is the most rational method in this study.

Korea has the tenth largest film industry in the world; however, detailed analyses using the factors contributing to successful film commercialization have not been approached. Using big data, this paper analyzed both internal and external factors (including genre, release date, rating, and number of screenings) that contributed to the commercial success of Korea's top 10 ranking films in 2011-2015. The authors developed a WebCrawler to collect text data about each movie, implemented a Hadoop system for data storage, and classified the data using Map Reduce method. The results showed that the characteristic of "release date," followed closely by "rating" and "genre" were the most influential factors of success in the Korean film industry. The analysis in this study is considered groundwork for the development of software that can predict box-office performance.

Building Energy Efficiency Rating system was enforced in 2001 to enhance spreading high-energy performance and saving buildings. It was only for the new apartments, but expanded to new office buildings in 2010, and moreover, government offices require 1st grade of Building Energy Efficiency Rating system. Green Building Act, which is established to reduce the emissivity of carbon dioxide by reducing building energy consumption, will be enforced in 2013, and new apartments and office buildings will be subjected to it. Henceforward, it will extend to other types of buildings and will be phased in. In general, pumps and fans consume approximately half of the air-conditioning energy consumption, and about a quarter of the total building energy consumption when office buildings have total floor area of more than 10000 square meters. This study analyzed the energy demand when applying VAV(Variable Air Volume) and VWV(Variable Water Volume) System to reduce energy returns of the pumps and the fans by ECO2, which is a computer simulation program used for Building Energy Efficiency Rating system.

In the framework of COMS(Communication, Ocean and Meteorological Satellite) programme, the first bipropellant propulsion system for GEO satellite has been developed successfully. So far Korea has its own experience of development of a monopropellant propulsion system for LEO satellites, i.e., KOMPSAT's. Other types of propulsion systems for a satellite, such as cold gas and electric propulsion etc., are being developed somewhere in Korea, however they are not commercialised yet, apart from those two systems aforementioned. This paper mainly focused on the design of the Chemical Propulsion System(CPS) for the COMS, joint scientific and communications satellite. It includes descriptions of the general system design and a summary of the supporting analysis performed to verify suitability for space flight. Essentially it provides an overview and guide to the various engineering rationale generated in support of the COMS CPS design activities. The manufacture and subsequent testing of COMS CPS are briefly discussed. Feasibility of COMS CPS to an interplanetary mission is proposed as well.

본 연구는 전라북도 군현단위의 지방관아를 중심으로, 근대기에 진행된 관아시설의 쇠퇴에 관한 연구이다. 다각적인 관련 자료를 토대로, 본 연구는 관아시설의 쇠퇴 요인과 양상을 파악하는 한편 쇠퇴의 핵심요인으로서 훼철과 전용에 관한 특징적 사실을 보다 구체적으로 살펴보았다. 나아가 이러한 쇠퇴 요인들이 발생한 구체적인 시점을 살펴봄으로써 시기별 쇠퇴 양상의 일면을 파악하였다. 이에 따른 연구 결과는 다음과 같이 요약 정리될 수 있다. 관아시설의 쇠퇴 요인은 훼철(毁撤), 폐지(廢止), 전용(轉用), 재해(災害)의 4가지로 구분된다. 훼철은 관아시설의 철거를 가리키며, 폐지는 관아시설의 쇠락과 운영의 중지를 의미한다. 전용은 공공기능을 충족하기 위한 시설로의 전환을, 그리고 재해는 태풍이나 화재에 의한 피해를 가리킨다. 이 중 훼철과 전용이 지방관아의 쇠퇴에 가장 큰 영향을 미쳤다. 관아시설의 멸실에 가장 직접적 요인이었던 훼철에는 기능적 측면에서 중요한 목적이 있었다. 행정과 통치에 필요한 공공시설의 신축(新築)이 바로 그것이다. 기존의 관아시설이 전용되기도 하였지만, 그 이면에는 공공시설의 신축을 위해 관아시설이 훼철된 여러 사례가 확인된다. 한편 관아시설의 전용은 교육, 행정, 금융, 치안시설로 구분되는데, 객사와 동헌은 각각 교육과 행정시설로, 부속시설은 금융과 치안시설로 활용되는 것이 일반적이었다. 특히 일부 관아시설은 주택이나 병원과 같은 특징적 시설로도 이용되었다. 전용과정에서는 관아시설의 내 외부에 걸쳐 많은 변형이 발생하였는데, 이로 인해 관아시설은 전통적인 양식을 잃어가며 점차 쇠락하였다. 관아시설의 쇠퇴는 시기적으로 1900년대부터 이미 시작되었으며, 1930년대에 이르러서는 관아시설의 대부분이 본연의 모습과 기능을 잃게 되었다.
