Recently, a high speed spindle is an essential part of machine tools to satisfy latest demand of high precision product and machining of hard materials. But, there are many disadvantages such as heat generation of built-in-motor, bearing friction, noise, vibration and displacement because of the high speed. Many researches on spindle systems have been conducted for solving these problems. In this study, technical trend of machine tools spindle systems are analyzed with patent PSM, mapping and grouping. The analysis is carried out for the applied patent during January 2000 and December 2009 in Korea, Japan, EU and U.S.A. And development of the direction, strategy and promising technologies of the spindle system are suggested.

This study investigates the developmental conditions of functional clothes for the elderly. First, preceding studies and relevant web sites were analyzed along with a survey of commercial functional elderly clothes in Korea. A KIPRIS patent information database was used to study registered and disclosed patents and utility models in order to analyze patent application trends in relevant fields. Patents were searched by year of application from 1990 to 2013. Keywords used for searching included 'senior, aged, and elderly'. Among collected data, overlapping and irrelevant data were excluded to select 162 cases for analysis. Details of analysis are annual patent application trends of functional elderly clothes, topic analysis, shape and characteristics. An examination of commercially available functional clothing products for the elderly indicated that most of products were developed in the form of inner wear or protective clothing for seniors who have bodily discomfort. An annual patent application of functional elderly clothes showed slight fluctuations; however, there was an overall increase. For patent topics, technologies related to secretion and excretion were the most at 47 cases total (29%), followed by 23 cases (14%) on biometric information technology. However, the development of relevant technologies seems necessary in the future as therapeutic function and fiber technologies gradually stagnate.

This study attempted to creat patent map 163 cases of patent for technology of apparel design using computer technology and researched the trend of Patent application by count교, technologies, applicant and filing date. In regard to application by country, the United States mark the first place with 99 cases (61%), Japan marks the second with 34 cases (21%), Korea the third with 19 cases (12%). Comparing the patent applications in specialized technologies, we find the United States is overwhelming the technologies for garment Production Process, Patterning Process and preparatory process, and Japan is currently undergoing development work in this area, while most of Korean applications are focused in the technologies for selection or substitution methods related to Purchase and sale of apparels, body image and design service Therefore, it is required to preoccupy and defend patent rights as well as develop technologies aggressively and extensively in preparation for the expansion of e-commerce market. Analysing the speed of progress in technology in terms of number of applicants and application cases, we can say it entered into developing stage from the middle of 1990s and it seems that they will continue the development work from now on. in case of Korea, they began in 1996, somewhat late, but reached a similar level with the United States in 2000.

A technical analysis was conducted to predict the development trend for the highly efficient absorption type refrigeration system. The study was based on a submitted patent during January 1981 and December 2000 in Korea, Japan and America. The total number of extruded patents from the registered database was 24,822 and the filtering process makes the reduction of the data number to 3,510. Technical development of Japan for the absorption type refrigeration system is prominent compared to the other country due to approximately 75％ of the patents coming from Japan. When the patent is divided into two categories, the patent for component technology for the refrigeration system makes up 75％ and the refrigerating type technology 25％ of the patents. This shows technical development for the system component is advanced compared to the technology development for the system type. When the patents are classified by nationality of patent applicants, foreigners contribute up to 33％ of the patents in Korea. However, Japan's case shows the 99％ of the patents are invented by the Japanese. If the patents are classified to the International Patent Classification, most of the data for the absorption type refrigeration system belongs to IPC F25B.

The main objective of this study is to analyze the structure of efficiency of R&D input variables and the attributes of patent information as output of R&D activities in the major manufacturing industries (electric & electronics, machinery, chemical, textile) from the mid-1970s to the late-1990s by the development of "mapping technique". To attain this objective we first have examined the attribute of time-lag which depends on the absolute, and the cumulative values between input and output. And on the basis of this result, we have made an analysis on the impact to extract the main variables affecting patent by industries. Moreover, according to time trend of the impact variables, we have analyzed the structure of R&D efficiency, and of technological progress which will be changed with time by patent information. It has been aimed at constructing technological progress patterns in the Korea industry.

The objective of this study is to investigate patent trends of Daegu city which tries to introduce environment friendly energy and to develop new technology or new industry sprung from technology convergence on smart decentralized energy technology and other technologies. After applying network analysis to corresponding groups of technology or industry convergence, strategy for future energy convergence industry is provided. Patent data applied in Daegu city area are used to obtain research goal. The technology which contains several IPC codes (IPC Co-occurrence) is considered as a convergence technology. Path finder network analysis is used for visualizing and grouping by using IPC codes. The analysis results categorized 13 groups in energy convergence industry and reclassified them into 3 cluster groups (Smart Energy Product Production Technology Group, Smart Energy Convergence Supply Technology Group, Smart Energy Indirect Application Technology Group) considering the technical characteristics and policy direction. Also, energy industry has evolved rapidly by technological convergence with other industries. Especially, it has been converged with IT industry, and there is a trend that energy industry will be converged with service industry and manufacturing industry such as textile, automobile parts, mechanics, and logistics by employing infrastructure as well as network. Based on the research results on core patent technology, convergence technology and inter-industry analysis, the direction of core technology research and development as well as evolution on decentralized energy industry is identified. By using research design and methodology in this study, the trend of convergence technology is investigated based on objective data (patent data). Above all, we can easily confirm the core technology in the local industry by analyzing the industrial competitiveness in the macro level. Based on this, we can identify convergence industry and technology by performing the technological convergence analysis in the micro level.

건축물은 전세계 총 에너지 소비 및 온실가스 방출의 1/3 이상을 차지하고 있어 건축물이 환경에 미치는 영향이 크다. 이에 따라 각 국가에서는 1997년 교토의정서에 의해 온실가스 배출량을 감축할 것을 의무화하였으며, 한국도 2014년 건축물 에너지 성능개선 방안을 발표한 바 있다. 본 연구는 에너지 절감이 가능한 친환경 건축물 기술분야의 주요 핵심기술을 소분류로 분류한 후, 한국, 미국, 일본 그리고 유럽에 공개된 특허문헌에 대한 특허동향분석을 수행하였다. 본 연구의 목적은 주로 친환경 건축물의 인증제도 그 자체에만 머무르고 있어서 세부적인 기술현황이나 연구개발방향을 정확하게 설정하지 못한다는 현재 기술의 문제점을 해결함으로써, 향후의 체계적인 R&D 방향제시 및 기술개발방향을 제시하는 것이다.

본 연구는 탄성파 탐사 수진기의 특허동향을 분석하였다. 또한 수진기 제조사인 페어필드, 서셀, 와이어리스 사이스믹 등 3개 주요 기업의 탄성파 탐사 수진기 특허동향 및 핵심특허의 기술특징을 분석하여 각 기업의 기술개발 세부분야를 살펴보았다. 탄성파 수진기의 특허동향은 2000년 초 중반 이후로 출원 증가율이 지속적으로 높아지고 있으며 최근 더욱 높은 증가율을 보여 동 분야의 성장세를 확인하였다. 동 기간에 주요기업의 특허 출원증가율은 글로벌 동향보다 높게 나타났으며 특허침해소송 사례를 확인하여 동 분야의 활발한 시장경쟁을 확인하였다. 핵심특허 33건의 기술특징을 분석한 결과 주요기업은 대체로 탄성파 신호감지 분야에 집중하여 특허를 보유하는 것으로 나타났다. 세부기술은 자료획득의 신뢰도 향상, 자료전송 효율 향상, 무선수진기의 운용 시스템 개량기술 분야로 구분되었다. 시장이 성장하고 있는 동 분야의 기술개발 및 제조 관련 신규 진입자는 향후 발생할 수 있는 특허분쟁 또는 중복연구 등을 미연에 방지하기 위하여 주요 기업의 제품 및 특허의 청구항을 면밀하게 분석할 필요가 있겠다.
