Big Data has spread rapidly in various industries since 2010. We analyzed the general characteristics of big data through time series analysis on the initial process of spreading big data and investigated the difference of diffusion characteristics in each industry. By analyzing papers, patents, news data, and Google Trend using Big Data as a keyword, we searched for data corresponding to the leading indicator, and confirmed that trends in news and Google Trend preceded the papers and patents by two years. We used Google Trend to compare the introduction period of domestic, US, Japan, and China and quantify the process of spreading the eight main industries in Korea through news data. Through this study, we present an empirical research method on how the general technology spreads in several industry sectors and we have figured out where the spreading speed difference of big data originated in each industry in Korea. The method presented here can be used to analyze the technology introduced from foreign countries in developing countries because it can be analyzed in diffusion process of other technologies besides big data and corresponds to the diffusion of technology keywords in a specific country. And, on the corporate side, this approach shows what path is effective when it comes to launching and spreading new technologies.

Even though papers and patents generated by public research institutions including universities are continuously increasing in Korea, commercialization of research outputs is significantly lower than developed countries. Therefore, it is very important to improve the effectiveness of technology licensing offices(TLOs) of universities. In this study, we study effects of the patent manager dispatch program(PMDP) of the Korean Patent Office(KPO) on the performance of TLOs. KPO has dispatched patent experts to selected TLOs under the PMSD since 2006. Based on data of 126 TLOs, we analysed whether the PMSD has improved the performances of beneficiary TLOs. We tested two related hypotheses: (1)Whether or not a TLO received the dispatch service had effects on its performance? (2)Were early beneficiaries more effective than late beneficiaries or non-beneficiaries because of cumulative learning effects? The main findings are as follows. The past experience in itself did not improve performances of beneficiary TLOs. However, early beneficiaries were better than late beneficiaries or non-beneficiaries, that is, some learning effects might help the beneficiary TLOs improve their performances.

Purpose: The purpose of this study was to find out the effect of hospice home care on the pain relief and quality of life of terminal cancer patients. Method: Experimental pre and post tests were provided to a single group to see the changes of quality of life of patients who were referred to a hospice home care department after having cancer treatment. They were visited at least 8 times for the duration of 4~6 weeks and were provided a 24 hour phone call service. 41 subjects were transferred to a hospice home care department after being discharged from hospital were selected. Result: 1)The first hypothesis that "the pain score of the subjects after receiving hospice home care would be different from before receiving hospice home care would be different from before receiving hospice home care" which scored 4.06 point at the first test and 3.41 at the second did not statistically show a significant difference(t=1.421 p=1.66), even though the pain score is decreased. 2)The 2nd hypotheses that "the quality of life score of the subjects after receiving hospice home care would be different from before receiving hospice home care" which scored 2.88 point at the first test and 3.39 at the second showed a significant difference(t=-6.759, p=.000) and was supported. Regarding the changes of quality of life score, social aspect(t=-5.745, p=.000), emotional aspect(t=-5.684, p=.000), and spiritual aspect(t=-6.889, p=.000) has significantly been increased, while physical aspect has been more decreased significantly than before the hospice home care is provided(t=4.282, p=.000). Conclusion: It was effective to provide hospice home care in relieving the terminal cancer patients' pain and in improving their quality of life, even though a short term hospice home care for 4-6 weeks was provided.

Free Trade Agreement (FTA) between the Korea, of the one part, and the EU and its member states, of the other part, has been effective, as of 1 Jul 2011. EU enlarged its members up to 27 countries including Romania and Bulgaria in 2007, and stood up as the second largest trading partner to the Korea right after the China. FTA, generally, shows the several different figures according to the countries concerned on the agreement The EU has long history and cultural, educational assets. In addition to that, the EU also has economical, industrial bases. Therefore, the EU seeks fruitful profits utilizing its intellectual property rights. There are copyrights and related rights, trade marks, geographical indications, designs, and patents, etc. on the Chapter 10. intellectual property rights of the Korea EU FTA. Among them, the others except geographical indications seem to be somewhat the terms advantageous to the Korea. It is possible to ask further requirements to the Korea in the years to come because the EU member countries are very much interested in the practical profits of intellectual property rights. Thus, it would be essential tasks for us to review the intellectual property rights protection and features of the Korea EU FTA.

Objective : To evaluate the effectiveness of Novalis shaped beam radiation treatment as an adjuvant treatment in patients with craniopharyngiomas. Methods : We reviewed 8 patients with craniopharyngiomas who had recurring tumors during follow-up or had residual lesions after primary surgery. Three of 8 patients were found to have recurrence after gross total excision of the tumor and 5 patents had residual lesions after subtotal resection. All patients were treated with fractionated stereotactic radiation treatment[FSRT] using Novalis system. The mean age of patients was 28 years [range $16{\sim}52$]. The median irradiation dose per fraction was 17Gy [range $1.7{\sim}2.0$]. The median fraction number was 23 [range $15{\sim}25$], and the median total dose was 39.1 Gy [range $25.5{\sim}42.5$]. Follow-up included MR imaging, and ophthalmologic and endocrine examinations. Results : The median follow-up period was 23 months [range $12{\sim}43$]. The local tumor control rate was 87.5%. One patient had a recurring tumor, in which cystic change developed 2 months after FSRT. Four patients showed a decrease in size of their tumor, while 3 patients remained stable. Seven out of 8 patients had hormonal dysfunction that remained unchanged after initial surgery. No further progression of visual impairment was observed. Conclusion : FSRT using Novais system is effective and safe for the treatment of recurring or residual craniopharyngiomas without toxicity like optic neuropathy.

This study relates to measure impact of green technology on industry sector by uses of industry greening indices. For this study, we performed patent trend analysis, technology-industry concordance analysis, and designed some industry greening indices. Through the results of this research, we found out the impact of Korean high priority green technologies on respective industries, and consequently identified which industries play an important role in the era of green innovation. IT related industries would catch somewhat weak attention in green technology policy, though they manufacture and use plenty of patents at present. Meanwhile, Energy related industry, such as battery industry would catch strong attention in green innovation, showed very high value of industry greening indices. In order to design proper R&D strategy for green technologies, understanding industry and market structure that can adapt and promote green technology innovation is important. In this context, this study could be an effective and systematic tool for assisting green innovation policy. Also, these indices developed are not limited to the case of green technology, other technologies can be used universally as a input for analysis.

Recently, with oil price jumping and environmental issues, Green ship is paid deep attention to by ship owner, operator, builder, class and government. Fuel efficiency and reduction of $CO_2$ emissions are expected to have a strong influence on the design and operation of merchant ships. Many ship owners and operators are seeking the more economic method by the best operating route and the application of reliable and effective energy saving devices. With the Energy Efficiency Design Index (EEDI) in 2013 attention will more than ever be focused at achieving maximum fuel economy in the hydrodynamic design of hull forms, their appendages and propellers. IMO requirements for $CO_2$ emission for ships will now be implemented for vessels ordered from 1st January 2013. So far, a lot of new idea and patents have been proposed, tested, claimed and applied for various kinds of ship type. This paper shows numerical and experimental work related to a study on a energy saving devices particularly for fuller ship such as merchant vessel of Tanker and Bulker. From the bare hull wake measurements, typical upper/lower asymmetry of hull wake at the propeller disk was found. The pre-swirl duct have been designed and reviewed to recover the loss of propeller running in that condition. The general function of the pre-swirl duct was set to work against this asymmetry of wake and generate pre-swirled flow into the propeller against the propeller rotating direction.

Purpose: This paper developed the framework for extracting strategies of research and business development (R&BD) based on the data envelopment analysis(DEA). Methods: DEA has been widely utilized in evaluating R&D efficiency. Even though, technology transfer and commercialization has been regarded as the important factors for practical R&D efficiency evaluation, most research have evaluated R&D efficiency by just using the DEA outputs such as the number of patents and papers. The technology transfer, commercialization and relations among costs and generated technology and commercialization are needed to be considered for more practical R&D efficiency evaluation. Thus, this research addressed a method on how to incorporate the commercialization factors into the R&DB efficiency evaluation, and improve the efficiency strategically in terms of R&D and B&D. To achieve this, this research utilized a two-stage network DEA model for R&BD efficiency evaluation. Results: The proposed framework was applied to the 15 public research institutes and the 34 universities for validation. R&BD efficiency for the 15 public research institutes and the 34 universities was evaluated, and the differentiated improvement strategies for the inefficient DMUs to improve their efficient were proposed. Conclusion: The R&BD efficiency would be effectively analyzed based on two-stage network DEA. It would be utilized for the effective strategy planning for cultivating R&BD.

Recently, project performance and management of government R&D program investing huge amount of budget is being focused. In this study, I built a model for estimating the performance creating paths of the government R&D program, then I analyzed the attributes of performances created by industries. I used simultaneous equations with FIML and examined the IT industry and CT industry of industrial technology innovation program using survey on R&D performance conducted by KEIT. On the analysis result, all the companies create the innovation performance through the government grants. However, the one who commercialize patents is SMEs in IT industry, and conglomerates in CT industry. SMEs in IT industry, which has characteristic of complex product, need extra self innovation activities even the government supports them. For improving the commercialization performance and technology development of SMEs in CT industry, it is effective when conducting cooperative research. These findings give us the implication that it is needed to consider different factors by industrial and enterprise characteristic when planning the public policy and government tasks.

Shape memory alloys(SMAs) have revolutionized the material engineering sciences as they exhibit exclusive features i.e. shape memory effect(SME) and super-elasticity. SMAs are those alloys that when deform return to their predeformed shape upon heating, they also restore their original shape by removing the load. Research on properties of newly advent of several types of ferrous based shape memory alloys(Fe-SMAs), shows that they have immense potential to be the counterpart of Nitinol(NiTi-SMA). These Fe-SMAs have been used and found to be effective because of their low cost, high cold workability, good weldability & excellent characteristics comparing with Nitinol(high processing cost and low cold workability) SMAs. Some of the Fe-SMAs show super-elasticity. Fe-SMAs, especially Fe-Mn-Si alloys have an immense potential for civil engineering structures because of its unique properties e.g. two-way shape memory effect, super elasticity and shape memory effect as well as due to its low cost, high elastic stiffness and wide transformation hysteresis comparative to Nitinol. Further research is being conducted on SMAs to improve and impinge better attributes by improving the material compositions, quantifying the SMA phase transition temperature etc. In this research pre-existing Fe-SMAs are categorised and collected in a tabulated form. An analysis is performed that which category is mostly available. Last 50 years data of Fe-SMA publications and US Patents is collected to show its importance in terms of increasing research on such type of alloys to invent different compositions and applications. This data is analysed as per different year groups during last 50 years and it was analysed as per whether the keywords exist in title of an article or anywhere in the article. It was found that different keywords related to Fe-SMAs/categories of Fe-SMAs, almost don't exist in the title of articles. However, these keywords related to Fe-SMAs/categories of Fe-SMAs, exist inside the article but still there are not too many publications related to Fe-SMAs/categories of Fe-SMAs.
