This research aims at developing and distributing models and indexes that can evaluate ubiquitous information projects in order to enhance the objectivity and validity of their evaluation. The research adopts a BSC(Balanced Score Card) concept with four views, economic, policy, social, and technical views. The research induces a model of pre-evaluation and a model of post-evaluation according to each view. In order to secure the validity of the models, they are revised and complemented by obtaining advice through interviews with five experts in related fields, and the validity and application possibility of the indexes are verified by surveying ten people working in those fields. Finally, investigating their weights according to the importance of each view and index, they are evaluated using an AHP (Analytic Hierarchy Process) method.

As the FTAs' implementations are accelerated, an Ex-post assessment, such as an analysis of the tariff schedule and agricultural trade has been emerging as an important national issue for an agricultural sector Korea-EU FTA, which was to be implemented in the five years from July 2016 as one of the giant FTA. The purpose of this study was to determine the demand of an ex-post assessment on agricultural sector as a trade negotiation procedural law. In addition, by providing policy direction for the agricultural policy part requiring amendments and supplements through ex-post assessment, the conflicting arguments between agricultural and non-agricultural sector can be evaluated more objectively. The current evaluation method on the economic impact ex-post assessment of a FTA is generally compared using the change in trade balance before and after the time of FTA implementation. On the other hand, this comparison cannot be said to be the pure FTA effects and objective, tightening economic impact assessment of the FTA in all combined situations, such as the effects of exchange rates and international macroeconomic changes and climate change & occurrence of pests. Over the last 4 years, however, Korea-EU FTA's total accumulated agricultural GDP loss was measured to be 2,178 billion by these research attempts with dynamic analysis as ex-post assessment methodology. The greatest impact was mainly livestock and pork followed by cereals and vegetables. In addition, this research is expected to contribute to policy evaluations in the future.

Four rice varieties (Boseogchal for waxy, Baegjinju for medium-waxy, and Seolgaeng and Haiami for non-waxy) were milled to 2% degree of milling (DOM), and physicochemical and sensory properties of 2% milled rice (2% MR) were compared to those of brown rice (BR). No significant differences in the approximate compositions of BR and 2% MR were observed, whereas the grain color of 2% MR was slightly brighter than that of BR. For all varieties, water absorption ratio of BR was significantly increased by milling. The pasting properties of rice varied significantly depending on the variety, but there was no significant difference in peak and through viscosities between BR and 2% MR. Analysis of the texture of cooked rice showed that milling to 2% DOM caused a significant decrease in hardness, but an increase in adhesiveness and stickiness. Cooked Seolgaeng 2% MR scored significantly higher in the sensory evaluation than the corresponding BR. These results suggest that 2% DOM would be useful for improving the sensory properties of cooked non-waxy rice.

The Ministry of Land, Transport & Maritime Affairs(former-The Ministry of Construction and Transportation)establish & promulgated the guide line of The Law of Post Evaluation on May 10, 2001(Article 58824-318) to public construction project under the Operation Law of Construction Engineering Management the 18 clause of Article 38 in order to induce & collect useful data about construction project when plan new similar project in the future about the initial planning phase, former and past accomplished businesses to construction works, results, efficiency, effectiveness. Ever since The Ministry revised 5 times, the former contents are composed for SOC, big volume civil project, and revised contents Article 2010-14(Jan 15, 2010) included some architectural project, but that was not definite the evaluation contents, direction & objective standard. So evaluation index implements are ambiguous about accomplished project. This research arranged the correctness evaluation indicators, criterions for decide the grades in order to helpful informations for similar architectural project in the future.

Post-Occupancy Evaluation (POE), which is one of the construction environment evaluation methods, is a series of processes that ask about the functional requirements and satisfaction of an object from a life cycle perspective such as design/construction/residence. However, there are no POE research activities targeting large-scale units. On the other hand, large-scale third-phase new towns are being developed. Therefore, this study conducted a post-residence evaluation (POE) research activity in a large-scale unit (Multifunctional Administrative City). The procedure of this study is to conduct a literature survey on the current status and implications of the multi-functional administrative city area, and based on the research data, derive the Happy City evaluation index for the major issues and special issues of the Happy City. Afterwards, 450 questionnaires were conducted for the residents of Happy City, and POE analysis was performed on the derived data for each module. And based on the analysis results, implications such as problems and improvement points for the current status of the Happy City were derived. This can be used as a basis for the expansion of a large-scale new city into a self-sufficient city, and it can be used as a basic data for the development and improvement of a happy city that meets social needs in the future.

According to the post evaluation scheme in Korea of a public construction project which is more than 30 Billion KRW, project performance is evaluated by investigating outcomes and effects of the construction after the completion of the project. The current post evaluation results can be used for planning and estimating a construction project in the future. However, it is not easy to utilized for an on-going project because the system does not provide the phase-based performance of a project. Although project planning performance is important for project initiation, few attempt has been made to evaluate planning performance in Korea. The purpose of this study is to provide a conceptual performance evaluation of planning performance using preliminary feasibility study conducted by Korea Development Institute. This study developed a planning performance database using data extracted from preliminary feasibility study reports of the completed 354 road construction projects. This study analyzed the performance of the planning stage of road projects by developing absolute metrics such as standard construction cost and standard construction schedule based on a Lane-Km. Using the standard construction cost and schedule metrics, the planning performance was analyzed by project characteristics. The results of this study can be used for phase-based performance evaluation from planning phase to construction phase.

According to the expansion of smartphone penetration and development of wearable device, personal context information can be easily collected. To use this information, the context aware recommender system has been actively studied. The key issue in this field is how to deal with the context information, as users are influenced by different contexts while rating items. But measuring the similarity among contexts is not a trivial task. To solve this problem, we propose context aware post-filtering to apply the context compensation. To be specific, we calculate the compensation for different context information by measuring their average. After reflecting the compensation of the rating data, the mechanism recommends the items to the user. Based on the item recommendation list, we recover the rating score considering the context information. To verify the effectiveness of the proposed method, we use the real movie rating dataset. Experimental evaluation shows that our proposed method outperforms several state-of-the-art approaches.

This paper describes an algorithm to suppress composite noise in a two-microphone speech enhancement system for robust hands-free speech communication. The proposed algorithm has four stages. The first stage estimates the power spectral density of the residual stationary noise, which is based on the detection of nonstationary signal-dominant time-frequency bins (TFBs) at the generalized sidelobe canceller output. Second, speech-dominant TFBs are identified among the previously detected nonstationary signal-dominant TFBs, and power spectral densities of speech and residual nonstationary noise are estimated. In the final stage, the bin-wise output signal-to-noise ratio is obtained with these power estimates and a Wiener post-filter is constructed to attenuate the residual noise. Compared to the conventional beamforming and post-filter algorithms, the proposed speech enhancement algorithm shows significant performance improvement in terms of perceptual evaluation of speech quality.
