In this article, the elements usually included in the official documents issued by the Chosun Governor General office, the process of a certain document being put together and legally authorized, and its path of circulation and preservation are all examined. In order to create an official document of the Governor General office with legal authorization, a draft of a bill had to go through several discussions and a subsequent agreement before it was finally approved. Personnels involved in the discussion stage had the authority to ask for modifications and retouching of the draft, and the modifying process were all recorded in order to make clear who was responsible for a certain change or who objected to what at any given stage of the process. The approved version of an official document was called the 'Completed one(成案), and it was issued after the contents were turned into a fair copy by the office that originated the draft in the first place. With the original finalized version left in custody of that office, the fair copy was handed over to the Document department which was responsible for issuing outgoing documents. After the document was issued and the contained orders were carried out, the originally involved offices began to classify the documents according to their own standards and measures for safekeeping, but it was the Document department that was mainly responsible for document preservation. The Document department classified the documents according to related offices, nature of the documents(편찬류별), and most suitable preservation methods(보존종별). The documents were made into books, and documents to be permanently destroyed were handed over to the Account office where they would be demolished. The manners of document processing of the Chosun Governor General office was in fact a modified version of the manners of the Japanese government. Modifications were made so that the process would be more suitable to the situations and environment of the Chosun society. The office's managing process was inherited by the Chosun government after the Liberation, and cast a significant impact upon the document managing manners of the Korean authorities. The official document administration of the Chosun Governor General office marked both the beginning of the colony document administration, and also the beginning of a modernized document managing system.

인류는 백만 년 전부터 줄곧 서서 직립을 향하여 진화 되어왔다. 그러나 산업사회에 접어들며, 불과 몇 십 년 전부터 앉아서 일하는 시간이 비정상적으로 많아짐에 따라 인류의 신체는 좋지 않은 영향을 받았다. 선행된 의학 연구들을 살펴보면 장시간 앉아 일하는 환경이 그 동안 우리가 알고 있었던 성인병의 원인에 상당 부분 악영향을 끼쳤다고 밝혀왔다. 인류는 움직이는 방향으로 진화되어왔다. 그렇기에 현대 사회처럼 한 공간에서 앉거나 서서 움직임 없이 장기간 있는 것은 인체에 여러 부작용을 가져온다. 이러한 배경을 반영하여 본 연구에서는 스탠딩 책상을 이용한 기존의 서서 일하는 업무환경에서 진화생물학적 관점으로 한 발 더 나아가 걷는 환경에서의 업무에 대해 생각하게 되었다. 또한 스마트워크의 한 종류이자 스마트폰을 현장에서 직접 사용하는 모바일오피스 환경의 확장을 기대하며 스마트폰으로 작업을 처리하는 실험을 실행하고자 한다. 이 연구는 스마트워크의 한 종류인 모바일오피스 환경이 구축되고 정착하는데 기여를 할 수 있다. 또한 스마트폰을 이용하는 업무 뿐 아니라 돌아다니면서 일을 하는 업무환경 역시 개발 될 수 있다. 더 나아가 기업의 업무 환경, 학생들의 공부환경의 패러다임이 바뀔 수 있을 것이다.

자율주행자동차(Automated Vehicle, AV)의 상용화를 위해서는 ADS의 운행가능영역(Operational Design Domain, ODD)이 명확하게 정의되어야 하며, AV 관련 이해관계자들이 ODD에 대해 모두가 동일한 기준을 가지고 동일한 수준으로 이해할 수 있도록 공통된 언어와 일관된 양식이 마련되어야 한다. 따라서, 국외에서는 표준화된 ODD 프레임워크를 제시하고, ODD를 기반으로 ADS 특정 기능을 평가할 수 있는 시나리오 개발에 박차를 가하고 있다. 하지만, ODD는 도로환경, 기상환경, 교통환경 등 해당 국가별 특성이 반영된 조건이 포함되기 때문에 국외에서 정의된 항목을 그대로 적용하는 것이 아니라, 그 항목의 의미를 명확히 이해하고 국내의 여건을 반영하여 이를 정합화할 필요가 있다. 따라서, 본 연구에서는 국제표준을 기반으로 국내 주행환경을 분석하여 ODD 분류 체계 국내 최적화를 수행하였으며, 개발된 국내 ODD 항목을 기반으로 현재 운영 중인 자율주행차 시범운행지구(서울 상암, 광주)의 주행환경을 조사하고 그 결과를 바탕으로 시험운행지구별 ODD의 범위를 비교하였다.

Petroleum is the most used energy source in Korea with a usage rate of 39.5% among the available 1st energy source. The price of liquid petroleum products in Korea includes a lot of tax such as transportation·environment·energy tax. Thus, illegal production and distribution of liquid petroleum is widespread because of its huge price difference, including its tax-free nature, from that of the normal product. Generally, illegal petroleum product is produced by illegally mixing liquid petroleum with other similar petroleum alternatives. In such case, it is easy to distinguish whether the product is illegal by analyzing its physical properties and typical components. However, if one the components of original petroleum product is added to illegal petroleum, distinguishing between the two petroleum products will be difficult. In this research, we inspect illegally produced gasoline, which is mixed with methyl tertiary butyl ether (MTBE) as an octane booster. This illegal gasoline shows a high octane number and oxygen content. Further, we analyze the different types of green dyes used in illegal gasoline through high performance liquid chromatography (HPLC). We conduct component analyses on the simulated sample obtained from premium gasoline and MTBE. Finally, the illegal gasoline is defined as premium gasoline with 10% MTBE. The findings of this study suggest that illegal petroleum can be identified through an analytic method of components and simulated samples.

Objective: As a cue for desired mood, we attempted to identify types of sitting postures when people are involved in various tasks during their working hours. Background: Physical behaviors in reaction to user contexts were studied, such as automated posture analysis for detecting a subject's emotion. Sitting postures have high feasibility and can be detected robustly with a sensing chair, especially when it comes to an office. Method: First, we attached seven sensors, including six pressure sensors and one distance sensor, to an office chair. In Part 1, we recorded participants' postures while they took part in four different tasks. From the seven sensors, we gathered five sets of data related to the head, the lumbar, the hip, thigh pressure and the distance between the backrest and the body. We classified them into four postures: leaning forward, upright, upright with the lumbar supporting, and leaning backward. In part 2, we requested the subjects to take suitable poses for the each of the four task types. In this way, we compared the matches between postures and tasks in a natural setting to those in a controlled situation. Results: We derived four types of sitting postures that were mapped onto the different tasks. The comparison yielded no statistical significance between Parts 1 and 2. In addition, there was a significant association between the task types and the posture types. Conclusion: The users' sitting postures were related to different types of tasks. This study demonstrates how human emotion can interact with lighting, as mediated through physical behavior. Application: We developed a posture-based lighting system that manipulates the quality of office lighting and is operated by changes in one's posture. Facilitated by this system, color temperatures ranging between 3,000K and 7,000K and illuminations ranging between 300lx and 700lx were modulated.

This study was performed to deduct the extension possibility of the standards establishment for $NO_2$, $O_3$, Asbestos, Radon, total volatile organic compounds (TVOC) excluded in the indoor air part of Industrial Safety Acts in Korea. The air pollutants were sampled for 30 office buildings from August to September, 2005 in the metropolitan area. The airborne concentrations of $NO_2$, $O_3$, Radon and TVOC were 0.0092 ppm, 0.0035 ppm, 0.57 pCi/L and $423{\mu}g/m^3$, respectively. The management plan and reduction methods is required in the aspect of indoor air quality(IAQ) because the emission sources of those also exist in indoor as well as outdoor even though those were not exceeded the standards of the Ministry of Environment in Korea. The standard for TVOC in the new and remodeling office has to be established based on the risk assessment when hazard index exceeded "1" in the worst case scenario. In the state of art, the management of each volatile organic compounds has a difficulty due to not enough data for toxicological reference. Therefore, it is suggested that first of all, the standard for TVOC be established and then expanded to each materials for decision-making of improvement of IAQ in office.
