  • This research developed integrated service assessment index on satisfaction with road use in consideration of not only quantitative parts, such as the existing traffic speed and delay but also qualitative parts, such as traffic information and traffic safety, etc. The newly devised assessment index developed assessment items and weight using ANP analysis method through the existing research results and questionnaire survey on traffic experts and road users. To verify the developed assessment index, this research measured the feeling degree of road users in time of their driving and analyzed the reasons using the brain waves tester; as an analysis result, the speed shown in the existing assessment index was found to have a 35% effect and further, the factors, such as traffic safety and traffic information were also found to have a lot of effects on the road $users^{\circ}{\emptyset}$ feeling degree. Accordingly, the integrated assessment index suggested by this research has its significance in that it is available to assessment in view of users rather than the existing satisfaction with the service in road use, and this index was developed to reflect the needs of the times, such as a fine view of roads, traffic information, and traffic safety.

  • The Government is putting efforts to enhance efficiency and productivity of performances of National R&D Programs by enacting 'Law on Evaluation and Management of Performances of National R&D Program'. This study is the result of development of evaluation model and indices for analysis of efficiency through meta evaluation method for the specific evaluation among evaluation systems for National R&D Program that are being carried out at government-wide level. Meta evaluation model for analysis of efficiency of evaluation system for National R&D Program designed evaluation indices by categorizing compositional factors into 5 categories, namely, evaluation context factor, evaluation resources factor, evaluation process factor, evaluation result factor and evaluation utilization factor. Furthermore, the result of verification of reliability on evaluation composition factors and evaluation indices analyzed to select evaluation items displayed Cronbach' $\alpha$ coefficient of 0.933, thereby illustrating that there is no major problem in the evaluation index system. In addition, computation of weight for each evaluation composition factor and evaluation index was analyzed by using analytical hierarchy process (AHP) technique. The result of analysis displayed overall consistency index of less than 0.1 for the investigators, thereby enabling analysis that there is consistency in investigators.

  • In metropolitan cities have been reorganizing the routes of the city buses periodically due to changes in the spatial structure and traffic pattern and the lack of supply due to new developments. However, there is a lack of system to comprehensively evaluate the routes. Even if the evaluation index is not clearly defined, it may not be reasonable. Therefore, it is difficult to set the improvement direction when the bus route is reorganized. In this study, the existing evaluation indexes were reviewed and further investigation was conducted on the problematic indexes. In particular, the degree of curvature has been used as a very important index in the evaluation of the route system, but the existing curvature based curvature has a limitation in considering the traffic characteristics of individual users. For this purpose, a virtual city bus network was set up and the degree of curvature was calculated and compared based on the point - based curvature and stopping point based on individual user O/D. In this study, it is considered that more efficient and practical analysis and evaluation are possible in the evaluation of the city bus route system through the curvature considering the individual user O/D based on the stopping point. It is expected that it will be used at the time of reorganization of city bus route performed by individual local governments in the future.

  • 대한민국에서 3DTV 방송서비스는 더 이상 '미래방송서비스'가 아니다. EBS는 올해 4월 지상파 DTV 주파수에서 세계최초로 2D/3D 혼용방송서비스를 실시하였으며, 오는 10월 15일에는 APC(Automatic Program Controller)와 연동하여 방송스케줄에 따라 자동으로 3D 방송을 송출하는 시스템을 구축하여 2차 시범방송을 진행할 예정이다. 이렇게 3D 방송을 위한 기술적 준비는 차근차근 이루어지고 있음에 반하여, 3D 방송서비스에 대한 시청자의 호응은 그다지 크지 않다. 이것은 방송되는 3D 콘텐츠의 양과 질이 부족하기 때문으로 풀이된다. 이 같은 3D 방송서비스의 장애요소에 착안하여, 본 논문에서는 3D 콘텐츠 제작효율을 높이고, 만들어지는 3D 방송콘텐츠의 품질을 높이기 위한 하나의 방법으로서, 제작현장에서 활용할 수 있는 3D 콘텐츠 제작과 밀접한 관련이 있는 새로운 참조지표인 '입체충실도(Depth Fidelity)'를 정의하여 제안하고자 한다. 입체충실도를 도출하기 위해 우선 양안식(兩眼式) 3D 입체영상의 특징을 분석하였고, 시청자 체감 가상깊이를 계산하여 활용하였다. 또한 연구를 통해 도출한 입체충실도 계산 알고리즘이 적용된 EBS 입체계산기(Stereoscopic Calculator) 애플리케이션을 개발하여 안드로이드 스마트폰에서 이용할 수 있도록 함으로써, 카메라감독과 프로듀서 등 방송제작 현업 스태프들이 연구결과를 활용할 수 있도록 했다.

  • This study aims to derive the effect of road traffic noise perception by the visual and aural information through a laboratory experiment. To verify the result more precisely, ME(Magnitude Estimation) and SD(Semantic Differential Method) evaluation on the effect of visual and aural effect were carried out by 43 university students. As the result, up to 10% of psychological reduction effect was shown under the 65dB(A). As the noise level, it was analyzed that the vision affected about 7dB(A) and sound affected 5dB(A). However, if these two are given simultaneously, mainly sound affects to reduce the annoyance of noise and the vision next. Compared with the urban central circumstances, this effect(2dB(A) under 65dB(A) noise) was shown smaller than field test.

  • The study demonstrated the pre-feasibility evaluation of the new agricultual technology R&D project and the ways to improve it. The study created new criteria for pre-feasibility evaluation based on the results acquired from the examination and analysis of pre-feasibility evaluation systems and criteria of various institutions at home and abroad in order to understand the current state of the evaluation method conducted by the Rural Development Administration and to seek ways for its improvement. The new criteria include indices for technicity, marketability, and feasibility. Based on these, questionnaires were prepared and the answers on them were statistically analyzed to set weights between indices. It was found that feasibility appeared the highest, in particular, feasibilities related to budget appropriateness, novelty, possibility of demand for the technology, and potential of commercialization appeared high. Referring to this conclusion, a simple operation process of pre-feasibility evaluation was introduced in the study.

  • Steroid induced bone loss is a serious problem in frequently relapsing nephrotic syndrome especially in growing children. In order to evaluate whether $1-(OH)D_3$ (IL Sung Pharma.Co.) is effective in preventing steroid induced bone loss, we gave $0.5{\mu}g$ of $1-(OH)D_3$ for one year to forty patients with frequently relapsing nephrotic syndrome, receiving longterm prednisolone therapy (mean duration $50.12{\pm}29.40$ months). We checked the following markers before and after $1-(OH)D_3$ therapy. i.e. bone mineral density(BMD) using dual energy X-ray absorptiometry(DEXA) at the 2nd to 4th lumbar spine, serum calcium, phosphorus, parathyroid hormone(PTH), osteocalcin and urine pyridinoline(U-PYD). BMD($g/cm^2$) was increased even steroid therapy from $0.71{\pm}0.0\;to\;0.73{\pm}0.0$ (p<0.05). Lumbar spine BMD is a sensitive marker for evaluating steroid induced bone loss in children receiving longterm corticosteroid therapy and that $1-(OH)D_3$ appears to be effective in treating and preventing steroid induced bone loss.

  • This study draws implications by surveying and analyzing performance evaluation cases in Korea and overseas, and analyzes qualitative and quantitative performance evaluation indexes and evaluation models that fit the national R & D performance evaluation system through analysis of patent creation performance data or company status data. Also, in order to apply this to a specific group of companies with excellent exports and technical skills, we will conduct a case study on the performance analysis of patent strategy support projects based on the results of the survey. Although this study has some limitations in developing performance evaluation indicators due to the limited scope of business or business characteristics of the patent strategy support project, the qualitative evaluation system can be reviewed through previous studies and domestic and overseas case studies. Due to the problem of accessing and collecting data related to the performance of the support project, there is a limitation that performance analysis cannot be performed at a sufficient level. Nevertheless, after the completion of R&D support projects and patent strategy support projects, follow-up performance analysis can be performed through follow-up surveys. It is expected to be possible.

  • The new conjunctive surface-subsurface flow model at a large scale was developed by using a 1-D Diffusion Wave (DW) model for surface flow interacting with the 3-D Volume Averaged Soil-moisture Transport (VAST) model for subsurface flow for the comprehensive terrestrial water and energy predictions in Land Surface Models (LSMs). A selection of numerical implementation schemes is employed for each flow component. The 3-D VAST model is implemented using a time splitting scheme applying an explicit method for lateral flow after a fully implicit method for vertical flow. The 1-D DW model is then solved by MacCormack finite difference scheme. This new conjunctive flow model is substituted for the existing 1-D hydrologic scheme in Common Land Model (CLM), one of the state-of-the-art LSMs. The new conjunctive flow model coupled to CLM is tested for a study domain around the Ohio Valley. The simulation results show that the interaction between surface flow and subsurface flow associated with the flow routing scheme matches the runoff prediction with the observations more closely in the new coupled CLM simulations. This improved terrestrial hydrologic module will be coupled to the Climate extension of the next-generation Weather Research and Forecasting (CWRF) model for advanced regional, continental, and global hydroclimatological studies and the prevention of disasters caused by climate changes.
