This study examined characteristics and usefulness of middle-aged and older people's vocational training participation. Among sub-age groups categorized by the position in career cycle and the employability, 61~68 year old group(after retirement age group) had the biggest difficulties on the training including computer-based training and showed the lowest employment result compared to other sub age groups; major career(30~45), career transition preparation(46~52), career transition(53~60). However, the career transition age group utilized vocational training in the aspect of career search and the after-retirement age group in the aspect of preparation for older age and hobby. On the other hand, factors such as career adaptability and perceived education difficulties affected on the training usefulness in the aspects of career search and preparation for older age and hobby while perceived career barriers, career relevancy and relationship ability affected on the employment result. Based on these findings, this study suggests that vocational training provide more suited course for the boundaryless career seekers and include relationship enforcement and positive attitude development to overcome perceived career barriers for middle-aged and older people.

This study on land use and regeneration of urban central district in Daegu investigates the current trend of those changes, and examines the change of urban core on land use, Since the 1980s, large cities in Korea have experienced the decline of spatial economic activities as well as population. Such urban decline has a relation with land use which can be classified with urban land use district and actual land use. This study tried to capture urban land use in three aspects; downtown business, residence, and the change of land use conversion. Based on land use characteristics, the size of residence land use has played a major role in hindering of the efficiency of land use. Also, this study has reviewed urban renewal projects in Daegu, especially urban core renewal projects, and discussed the problems of the projects.

This study attempted to seek policy directions for development of sustainable urban industrial space through reviewing recent policies and projects of US cities that experienced urban industrial land replacement and industrial suburbanization. The policies and regulations for the urban industrial space preservation include the New York City's Industrial Business Zone, Chicago's Planned Manufacturing District, the no-net-loss framework in San Jose, and the subdivided and the state of the art in zoning systems in Philadelphia and Seattle. These policies and zoning systems have been effective for preventing the conversion of urban industrial lands to other uses, promoting business activities, and creating jobs for urban residents. In addition, the updated and innovative zoning systems allow for a wide variety of urban industrial spaces to meet newly emerging industrial demands. On the other hand, we suggested several policy implications through reviewing the cases of urban regeneration projects in Portland's Willamette Industrial Urban Renewal Area, Atlanta's BeltLine, and Milwaukee's Menomone Valley as follows: 1) updating and reinforcing spatial planning and policies for preservation and revitalization of urban industrial land; 2) considering existing businesses and local workers first; 3) setting up a participatory planning for local workers and residents; 4) preparing policies for brownfield cleanups.

Modeling urban climate caused by land use conversion is critical for human welfare and sustainable development, but has hampered because detailed information on urban characteristics is hard to obtain. With the advantage of satellite observations and the new statistical boundary system, this paper measures the economic and environmental effects of green area loss due to land use conversion in urban areas. To perform this purpose, data were collected from the various sources basic statistical unit data from the National Statistical Office, digital maps from the National Geographic Information Institute, satellite images, and field surveys when necessary. All data (maps and attributes) are built into the geographic information system (GIS). This paper also utilizes Landsat TM 5 imagery of Daegu city to derive vegetation index and to measure average surface temperature. The satellite data were examined using standard image processing software, ERDAS IMAGINE, and the results of the digital processing were presented with ARCVIEW(v.3.3). SAS package was used to perform statistical analyses. This study presents that there exists a strong relationship between land use change and climatic change as well as land price change. Based on results of the analysis, this paper suggests that planners should implement effective tools and policies of urban growth management to detect environmental quality and to make right decisions on policies concerning smart urban growth.

The primary purpose of this study is to identify the characteristics of land use change at the urban fringe. For this purpose, the Daegu Metropolitan City is selected as a study area. Land use changes between 1990 and 2000 in fringe areas are identified by processing Landsat TM5 imageries. The main findings are follows: First, land development has been driven by residential development, especially large-scale residential development encouraged by the two-million housing construction plan. Second, the type and size of the land use conversion are not identical across the study area. For example, the main land use type of the newly developed area of Buk-gu is residential use while that of Suseong-gu is public use. Third, most of residential development type is a high-density development which is quite different from American type of low-density development.

This paper examines the recent changes of urban center in metropolis in terms of land use. Jung-Gu, Daegu City is analyzed for a case study, and publicly notified individual land price data of 2000 and 2011 are used as analysis materials. The analyzing results show that a lot of residential land uses diminished in urban center, but residential function is still significant despite such decrease. Commercial land uses also decreased. Office land uses increased, but the increase is insignificant. On the contrary, unused or miscellaneously used land increased considerably. The phenomena implicate that land uses in the urban center are not positive under the influence of inner city decline. Overall, more land use changes occurred in the frame than in the core of urban center. That is, land uses in the core is more stable than them in the frame. However, decreasing commercial land uses in the core is noticeable, comparing to the frame. Mixed land uses for residence and commerce are most deconcentrated and office land uses most concentrated. Mean center point and standard deviation distance of land uses did not change significantly from 2000 to 2011, despite considerable change of land uses. The finding reveals that land use changes are widely occurring in urban center.

최근 스마트폰을 포함한 스마트 디바이스의 급속한 확산에 따라 모바일 통신 산업의 패러다임이 '음성통화'에서 '어플리케이션'으로 전환되고 있으며, 소비자들의 정보에 대한 인식이 "개발, 공유, 참여, 확산" 과정을 통한 개인화와 라이프 스타일의 변화 추구를 위한 용도에 많은 관심을 가지기 시작했다. 특히, 최근의 사물인터넷의 부각으로 인해 IoT(Internet of Things)와 스마트 디바이스와의 연동을 통해 주변의 센서로부터 수집된 정보를 직접 가공 처리하거나 제어하는 개인 중심의 생활밀착형 센서 앱 서비스를 제공하려는 다양한 시도가 이루어지고 있다. 본고에서는 스마트 디바이스에서의 센서와의 연동 및 적용 사례와 함께 IoT와의 융합기술 국내외 동향 등을 살펴보고자 한다.

원자재 가격상승과 유가 폭등으로 인해 국내 폴리에스터 업계는 중국 제품에 가격 경쟁력이 밀리는 범용 제품 비중을 줄이고 부가가치가 높은 광학 및 특수용도 제품 비중을 높여나가는 등의 노력에 주력하고 있다. 유가 인상과 단가 하락 압력, 경쟁 격화 등으로 포장재 등에 쓰이는 범용 PET 필름은 물론 확산필름 등 일반 LCD용 광학필름의 수익성이 낮아지면서 수익성이 좋은 분야의 비중을 확대하려는 움직임에 따라 올해 폴리에스터(PET) 필름 업계의 화두는 광학 및 태양전지에의 PET 필름의 적용 및 응용이었다. SKC가 먼저 광학필름의 원자재로 쓰이는 고순도 후막 베이스필름이나 태양전지나 하이브리드 자동차 부품용 필름 분야로 진출을 계획중이며 코오롱도 후막 필름 라인을 1기 증설하고 기존 포장재 라인도 전환키로 했다. 또한 도레이새한도 후막 필름을 주력제품으로 끌어올릴 계획을 갖고 있다. 본 고에서는 PET 필름 및 나일론 필름 수급동향을 살펴보고, 업체별 상황 및 전망을 살펴보도록 한다.

일본의 국립공원정책을 참고하고 본 연구의 결과를 통하여 세 가지 측면에서 나타나는 문제점에 대한 개선방안을 제시해보면 첫 번째 보전적인 측면은 용도지구 및 공원구역의 전면적인 재조정, 두 번째 이용적인 측면은 교통, 주차시설의 확충 및 도로체계의 재조정, 자연학습공간의 설치 및 환경교육(해설) 프로그램의 개발, 세 번째 관리적인 측면으로 도립공원 재원확보, 관리 인력의 증원 및 전문 인력의 배치 등을 들 수 있다. 나아가 공원구역의 전면적인 재조정으로부터 지역주민들의 의견수렴을 충분히 거친 후 자연보존지구에 대한 보존대책을 수립한 다음 도립공원 해제방안도 적극적으로 고려하여야 할 것이다. 그러나 보다 중요한 것은 일본의 환경정책을 예로 들었듯이, 환경보전적 측면에서 오히려 역행하고 있는 현행 우리나라 자연공원 정책이 전환되어야 한다는 것이다. 이에 환경보전적 측면을 중시한 자연공원법의 조속한 개정과 생물다양성을 관점으로 한 자연공원정책이 전개되어야 할 것이다.

기계적 mechanism에 의해 동력의 전달 또는 방향을 전환할때 상대적으로 움직이는 두 면에서 필연적으로 발생하는 마찰, 마모를 감소시켜 원활한 작동을 유지시켜 주는 물질을 윤활유라 한다. 이러한 윤활유의 기능은 두 마찰면 사이에 유체막을 형성하여 마찰 및 마모를 감소시키는 마찰, 마모 작용과 같은 1차 기능과 두 마찰면 사이에서 발생하는 열을 냉각시키는 냉각작용, 금속표면의 청정성을 유지시키는 방청작용, 두 마찰면을 밀봉시켜주는 밀봉작용과 같은 2차 기능으로 대별할 수 있다. 윤활유의 구성은 크게 윤활기유와 기유의 물성을 보완 또는 기유에 없는 물성을 나타내는 첨가제들로 구성되어 있는데 기유로는 주로 Paraffine계, Naphthenic계, Aromatic계로 탄소수 20~50의 탄화수소 혼합물로 이루어진 광유계 깅유와 물성과 용도에 따라 인위적으로 합성된 여러가지 합성기유가 사용된다.
