Many social and environmental changes emerged by the increasing of the number of the aged to entrance the aged society. This study explored the current supply status on Contents Technology R&D(research and development) of CT ministries and market policies(senior friendly industry) targeting to elderly consumers and the needs and demand of elderly generation to knowledge information technology. In, 2008, Ministries announced the sixth category of CT R&D's fundamental planning. The 'public culture service' to elderly and handicapped person is one of CT R&D category. This study investigated the information technology participation(internet participation rate, blog and internet cafe commitment) and contents technology to the elderly. The research indicated the desired needs of elderly consumers are creativity contents, emotional & experience and communication needs. These three factors of CT R&D to elderly consumers meets the needs non-game factors such as health, economic stability and information seeking in entertainment game.

This study analysed empirically the relationship between the CT R&D subsidy program and R&D performance of received company. According to the result, the CT R&D subsidy program is a significant factor to encourage R&D performance. Especially, the CT R&D subsidy program based on validity and reasonable system affects significantly the progress of R&D performance. Otherwise, the reasonable CT R&D subsidy program has a important role to play on company growing from a step of R&D to a step of the commercialisation performance. Thus, government should make an effort on researching data on market demand before implementing policy and communicating with company continually.

지금까지 변전소나 발전소에서 전류, 전압을 계측하는 수단으로서 주로 철심과 권선으로 구성되어진 변류기(CT), 계기용 변압기(PT)가 사용되어져 왔다. 최근, 2차측의 계측기나 보호 Relay의 Digital 화가 진전되어져 있다. 또한, Digital Network로 총합한 Intelligent 변전소가 시범적으로 구축되어짐에 따라 Digital Network에 대응한 초고압용 신형 CT, VD가 요구되어지고 있다. 상기와 같은 요구로 인해 당사에서는 기존의 CT.PT의 단점을 보완할 수 있는 245kV GIS용 로고스키코일형 CT와 Capacitive Voltage Divider를 개발 중에 있으며, 센서 자체의 특성시험에서 IEC 60044-7, 8 1Class 기준을 만족하는 특성을 얻을 수 있었다. 이러한 신형 CT.VD의 적용으로 종래의 CT.PT가 차지하는 공간이 필요 없게 되어 컴팩트한 GIS의 구조가 가능하게 될 것이다.

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.

This study examined the immunomodulatory effects of milk fermented with based on the synbiotic interaction between Cudrania tricuspidata leaf extract (CT) and Lactobacillus gasseri 505. Raw 264.7 macrophages were treated with milk (Control), milk supplemented with 0.2% CT (CT-milk), or CT-milk fermented with L. gasseri 505 (FCT). FCT-treated cells showed higher NO production than the other groups. ELISA revealed that FCT produced the highest enhancement of the production of pro-inflammatory cytokines such as $TNF-{\alpha}$, $IFN-{\gamma}$, $IL-1{\beta}$, IL-6, IL-2, IL-12, and IL-10. Furthermore, FCT also increased the gene expression of pro-inflammatory mediators such as iNOS and COX-2 in a concentration-dependent manner. Collectively, these results indicate that the synbiotic interaction between CT and L. gasseri 505 might enhance their immunomodulatory effects of fermented milk.

The purpose of this study was to predict abdominal obesity with 3-Dimensional computed tomography (3D CT) measurements of kidneys by analyzing the correlation between kidney sizes and abdominal obesity level. The subjects were 178 healthy adults without underlying diseases who had a comprehensive health examination at the Health Medical Center of Jesus Hospital in Jeonju. Abdominal obesity was measured by CT cross-sectional image at the level of the umbilicus and divided into visceral fat area, subcutaneous fat area, visceral fat/total fat ratio. The average comparison of kidney sizes classified according to abdominal obesity were performed through one-way analysis of variance (ANOVA) and Scheffe test. Pearson correlation analysis was performed to correlate all measurement values. The results of kidney size ANOVA analysis according to abdominal obesity were as follows. The means of kidney measurements according to visceral fat classification were significantly different in all kidney measurements (p<0.05). And in case of subcutaneous fat classification, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in the right kidney width (p<0.05). In case of visceral fat area/total fat area ratio, the means of kidney measurements by 3D CT of the severe obesity group were significantly different in both kidneys width (p<0.05). Pearson correlation between kidneys measurements and CT abdominal obesity showed that visceral fat area had the highest correlation with the left kidney width measured by 3D CT (r=0.467) and subcutaneous fat area had correlation with the right kidney width measured by 3D CT (r=0.249). The visceral fat area/total fat area ratio had correlation with the left kidney width measured by 3D CT (r=0.291).

The CT is all relation knowledge and technology which are applied to make the culture contents. Recently demand regarding the CT is increasing rapidly with a great growth and high technology of culture contents industry. In this paper we suggest a CT technology valuation model for promoting R & D results and technical diffusion of the CT. Also, It is shown how to derive a value of the CT using simulation. For it, we study a classification and distinctive characteristics of the CT. And this paper reviews the methods of technology valuation that have been developed by valuation specialists.

Background: Dosimetric comparison of two dimensional (2D) radiography and three-dimensional computed tomography (3D-CT) based dose distributions with high-dose-rate (HDR) intracavitry radiotherapy (ICRT) for carcinoma cervix, in terms of target coverage and doses to bladder and rectum. Materials and Methods: Sixty four sessions of HDR ICRT were performed in 22 patients. External beam radiotherapy to pelvis at a dose of 50 Gray in 27 fractions followed by HDR ICRT, 21 Grays to point A in 3 sessions, one week apart was planned. All patients underwent 2D-orthogonal and 3D-CT simulation for each session. Treatment plans were generated using 2D-orthogonal images and dose prescription was made at point A. 3D plans were generated using 3D-CT images after delineating target volume and organs at risk. Comparative evaluation of 2D and 3D treatment planning was made for each session in terms of target coverage (dose received by 90%, 95% and 100% of the target volume: D90, D95 and D100 respectively) and doses to bladder and rectum: ICRU-38 bladder and rectum point dose in 2D planning and dose to 0.1cc, 1cc, 2cc, 5cc, and 10cc of bladder and rectum in 3D planning. Results: Mean doses received by 100% and 90% of the target volume were $4.24{\pm}0.63$ and $4.9{\pm}0.56$ Gy respectively. Doses received by 0.1cc, 1cc and 2cc volume of bladder were $2.88{\pm}0.72$, $2.5{\pm}0.65$ and $2.2{\pm}0.57$ times more than the ICRU bladder reference point. Similarly, doses received by 0.1cc, 1cc and 2cc of rectum were $1.80{\pm}0.5$, $1.48{\pm}0.41$ and $1.35{\pm}0.37$ times higher than ICRU rectal reference point. Conclusions: Dosimetric comparative evaluation of 2D and 3D CT based treatment planning for the same brachytherapy session demonstrates underestimation of OAR doses and overestimation of target coverage in 2D treatment planning.
