한국은 반도체 산업에서의 독보적 우위에도 불구하고, 반도체 장비 분야에서는 두각을 나타내지 못하고 있다. 세정장비는 반도체 장비 중 한 분야로, 반도체 기술의 고도화에 따라 향후 중요성이 더욱 강조되는 분야이다. 본 연구는 특허 정보를 분석하여 한국을 포함한 주요 국가별 세정장비 분야 기술경쟁력을 파악하고 국가별 중점 기술분야를 살펴보고자 하였다. 이를 위해 최근 10년 간 미국 특허청에 등록된 세정장비 특허를 검색하여, 정량적 특허분석 및 특허 동시분류 네트워크 분석을 실시하였다. 연구 결과, 미국과 일본이 이 분야 기술을 선도하고 있는 것으로 나타났으며, 한국은 이들 선도국에 비해 경쟁력이 크게 뒤쳐짐은 물론, 경쟁국인 대만이나 후발국인 중국에 비해서도 우위에 있다고 보기 어려운 상황이다. 또한 국가별 전문화가 진행되어 있어, 국가 간 협력체제가 원활치 못할 경우 기술장벽으로 작용할 가능성도 없지 않다. 따라서 국내 세정장비 산업의 발전을 위한 적극적인 연구개발과 기술역량 확충이 요구된다.

Expectations for artificial intelligence technology are increasing, and its utility value is growing, leading to active use in the public sector. The use of artificial intelligence technology in the public sector has a positive impact on aspects such as improving public work efficiency and service quality, enhancing transparency and reliability, and contributing to the development of technology and industries. For these reasons, major countries including Korea are actively developing and using artificial intelligence in the public sector. However, artificial intelligence also presents issues such as bias, inequality, and infringement of individuals' right to self-determination, which are evident even in its utilization in the public sector. Especially the use of artificial intelligence technology in the public sector has significant societal implications, as well as direct implications on limiting and infringing upon the rights of citizens. Therefore, careful consideration is necessary in the introduction and utilization of such technology. This paper comprehensively examines the legal issues that require consideration regarding the introduction of artificial intelligence in the public sector. Methodological discussions that can minimize the risks that may arise from artificial intelligence and maximize the utility of technology were proposed in each process and step of introduction.

The transformation of sector system in Information and Communications Technology (ICT), a prominent character in sector system, has been paid much attention in innovation theory with rapid change in information technologies and technological environment. In this context, we explore how Sectoral Innovation System (SIS) in ICT has been transformed since 1970 by employing US patent data and Proxy variables which measures the basic elements for SIS and its technological characteristics. By utilizing patent data, it is demonstrated that technological regimes, key links and Schumpeterian patterns of innovation in overall ICT sector have drastically transformed over the last three decades. We also reviewed how changes of knowledge bases and technological characteristics driving forces of dynamics in ICT help heterogeneous agents interact with environmental factors (Industrial structure and institutions), leading to industrial or economic growth and its dynamics in the historical perspective over ICT sector (Telecommunication, Computer and Semiconductor). Consequently, our research shows clearly that Schumpeterian patterns of innovation have shifted from Mark I to Mark II in ICT. Our study also provides a glimpse picture of dynamics patent data.

An influence of inlet pressure on the performance of sector-shaped pad thrust bearings is investigated theoretically. The optimum conditions of film thickness or the optimum positions of pivot are found through the evaluation of load capacity for all available conditions of film thickness, under the operating conditions which the thermal and pad deformation effects can be neglected. The bearing performance including the inlet pressure effects is obtained for a wide operating ranges that inertia parameter(Re$^{*}$) is up to unity, and for the various cases of pad extent angle (number of pad) and the three cases of the angle between pads. The results show that the inlet pressure has a large influence on the performance of sector-shaped pad thrust bearings. In the design of sector-shaped pad bearings, due to the inlet pressure, the optimum number of pad is varied with the operating speed and the angle between pads, and the optimum position of pivot is located toward the leading edge along with the operating speed increases.

본 연구는 현재 감천항에 입항하는 선박교통 특성을 반영하여 감천항 도등의 효용성을 검토하였다. 감천항 도등은 1996년 4,000TEU 컨테이너선 출입항을 위해 감천항 항로표지 보완 기본설계과정에서 제안되어 설치되었다. 이후 부산지방해양수산청의 감천항 정온도 향상을 위한 기존 외곽 시설 재배치 검토 연구를 통해 50,000DWT급 일반 화물선 입항 대응 및 한진 부두의 크레인 높이를 반영한 도등으로 개선되었다. 그러나 현재 감천항의 해상교통 특성을 보면 해상교통 혼잡도도 원활하고 대형선박 보다는 10,000톤 이하의 중소형 선박 비중이 높아 대형선박 입항을 대응하기 위해 개선된 도등의 효율성은 감소되었다고 볼 수 있다. 그러나 입항선박의 규모에 따른 변화 추이를 보면 30,000톤 이상선박의 입항비율의 연평균증가율(CAGR)이 8.45%로 증가되고 있어 향후 대형선박의 입항비중 증가에 대한 대비를 위해서는 감천항 도등을 필수 등화로 유지하는 것이 필요하다. 따라서 도등을 철거할 경우 감천항 항로의 협소한 공간 특성상 입출항 선박이 조우하는 경우에는 충돌의 위험이 증가하여 항해자에게 큰 부담이 될 수 있기 때문에 도등의 기능은 유지하는 대신 전도등을 이전설치 하여 유지보수에 대한 부담을 경감시키는 방법과 도등의 기능 대신 지향등을 설치하는 방법을 고려해 볼 수 있다. 지향등 설치 시 인근 부산북항에 설치된 Single Sector Lights가 명확한 중시선을 제공하지 못하여 지점에 따라 명확한 구분이 어려움에 따라 이용자 만족도가 떨어지는 부분을 개선할 수 있는 Double Sector Lights를 설치를 고려해볼 수 있다.

● The current world is suffering abnormal climate caused by global warming. The main cause of global warming is greenhouse gas such as carbon dioxide. The carbon labeling system and carbon traceability system being pushed ahead in the agricultural sector is the policy for responding to climate change to reduce greenhouse gas emissions. To make this policy more effective and enhanced, the amount of carbon emissions should be calculated based on the kind of crops or the various businesses in the agricultural sector. Therefore, in order to estimate the accurate amount of carbon emissions, it is necessary to establish carbon dioxide emission intensity of various agricultural materials added onto the agriculture, and to calculate the amount of carbon dioxide emission for each crop according to agricultural production. The purpose of this study is to establish the amount of emission, emission per agricultural materials, of agricultural materials being added for crop production as a basic step, and emission intensity which can be used in the future market in order to estimate accurate amount of carbon emission in all the policies being promoted in the agricultural sector. Therefore, in this study, in order to build LCI D/B about organic fertilizers among many organic materials added onto the organic agriculture sector, one leading company in organic fertilizer production was selected and LCA was conducted for this leading company. We had to build the intensity and integrated average concept of intensity upon the two cases once production farmers for their own consumption and farms besides organic fertilizer company were categorized even if it's little amount. But in this study, individually produced organic fertilizers were excluded. Calculated results are following. Carbon emission of mixed expeller cake fertilizer in organic fertilizer was 1,106,966.89kg-$CO^2$ and emission intensity was 0.01606kg-$CO^2$, respectively. Total emission of mixed organic fertilizers was 241,523.2kg-$CO^2$ and emission intensity was 0.01705kg-$CO^2$. And total emission of organic compound fertilizers was 94,592.66kg-$CO^2$ and emission intensity was 0.01769kg-$CO^2$, respectively.

The purpose of this study was to investigate service support programs for the work-family balance in the community. Service support programs in the community are at beginning stages of development, because it has taken about 10 years to put a self-governing system into practice in Korea. This study concentrates on service support programs developed by various service organizations in the city and does not include any rural districts. First, the developmental process of the work-family balance model and type of the service support program in the community were studied. Next, the situation of care service support was examined based on written articles. Finally, a few suggestions were made f3r work-family balance in the community. The developmental situation of work-flmily balance in Korea is in a stage which is shifting from the company-leading model to a family-company-community model. The most common type of service support program offered in the community until now has been the informal sector through relatives, neighbors or friends. However, service support programs, in the public sector by the government and in the voluntary sector by nonprofit organizations and corporations, has rapidly been growing and the number of services from each sector has also increased. Profit organizations in the private sector, such as medical and care service centers, are also now rapidly increasing. It appears that service support programs contributing to the work-family balance in the community come from a number of sectors, including public, voluntary, private and informal sectors, to suit consumer needs.
