Boiled-type shrimp flavor was developed using Maillard reaction to reduce or mask fish odor or off-flavor in seafood. Model systems were created using enzymatic hydrolysate of shrimp and adding precursor compounds to increase flavor quality and stability. Amino acid precursors of cysteine and methionine and sugar precursors such as glucose, xylose, ribose and sucrose were tried and their flavor qualities were tested by sensory evaluation. After the optimal precursors were determined, the optimum reaction condition was investigated using pHs of 5, 6, 7, and 8 and reaction times of 1, 2 and 3 hours. The best precursors for boiled-type shrimp flavor were methionine and sucrose. The optimum reaction condition was pH 8.0 and a one hour reaction time.

In this study, safety education contents for medical radiation workers were produced based on Mixed Reality(MR). Currently, safety training for radiation workers is based on theory. This is insufficient in terms of worker satisfaction and efficiency. To address this, we created ICT(Information and Communication Technologies)-based MR radiation worker safety education content. The expected effect of Mixed Reality worker safety education content is that education is possible without space and time constraints, realistic education is possible without on-site training, and interaction between images is possible through reality-based 3D images, enabling self-directed learning Is that. In addition, learning in a virtual space expressed through HMD(Head Mounted Display) is expected to make education more enjoyable and increase concentration, thereby increasing the efficiency of education. A quantitative evaluation was conducted by an accredited institution and a qualitative evaluation was performed on users, which received excellent evaluation. The MR safety education conducted in this study is expected to be of great help to the education of medical radiation workers, and is expected to develop into a new educational paradigm as online education in accordance with Corona 19 progresses.

본 연구의 목적은 첫째 대학의 평가제도, 교육지원, 인적자원등과 같은 내부지원 요인이 기술이전 사업화 활동에 종사하는 관계자들의 기술이전 사업화 의욕에 영향 요인 인지 밝히고자 하였다. 둘째 이러한 내부 요인과 기술이전사업화 의욕의 인과관계에서 사회적 지지의 조절효과를 검증 하고자 하였다. 위 연구 내용을 분석 하기 위해 전국 40개 대학의 기술이전 사업화 조직에서 해당업무에 종사하는 산학교수, 직원을 대상으로 설문조사를 하였으며, 총160부를 배부하여 145부를 회수하였다. SPSS Statistics 22.0을 이용하여 분석한 결과는 다음과 같다. 첫째, 대학 내부요인, 즉 업적평가, 교육지원, 인적자원 모두 기술이전사업화 의욕에 유의한 영향을 미쳤다. 둘째, 대학내부요인과 기술이전 사업화 의욕과의 관계에서 사회적 지지의 조절효과를 분석한 결과, 업적평가와 기술 이전 사업화 의욕 관계에서 사회적 지지는 유사조절효과를 나타냈다. 하지만 교육지원 및 인적자원과 기술이전 사업화의욕 관계에서는 사회적 지지의 조절효과는 나타나지 않았다. 이 연구결과를 바탕으로 대학에서 기술이전 사업화 활동을 하는 사람중심의 지원정책수립에 시사점을 제공 하고자 한다.

Application examples of computational fluid dynamics (CFD) in the planning stage of high-rise buildings are introduced. First, we introduce examples of applications in the environmental field. The pedestrian wind environment was one of the earliest practical examples of CFD. CFD was also employed to validate the heat island mitigation measures proposed as part of the new construction plan. Second, application examples of wind-force evaluations are introduced. Prediction examples are presented for the peak wind pressure around a complex-shaped building and the wind force evaluation for a base-isolated building. The results prove that the results of the proper execution of CFD are equivalent to those of the wind tunnel experiment. As examples of CFD applications of other issues related to high-rise building planning, we introduce snow accretion on outer walls and high-temperature exhaust from emergency generators. Finally, the future prospects for the use of CFD are discussed.

This paper presents a new approach to evaluate the maximum number of simultaneous switching gates of a given combinational circuit. The new approach is based on an iterative method proposed by Sinogi et al. and applies a simulated annealing strategy to search jot a new solution. The experimental evaluation using ISCAS’85 benchmark circuits shows that the proposed approach has attained an excellent improvement compared with other rotated methods including the iterative method.

최근 IT 첨단기술의 발전과 더불어 국민들의 정보화 수준이 지속적으로 향상되고 있는 가운데 교통 분야에 IT기술의 최신분야인 유비쿼터스 기술 및 모바일 기술 등 첨단기술을 접목하려는 시도가 늘어나고 있는 추세이다. 이러한 경향에 발맞춰 교통사고 조사를 신속하고 효율적으로 실시할 수 있는 PDA 조사 장치가 개발되었다. 본 논문에서는 교통사고 조사를 위해 개발된 PDA에 대해 평가방법론을 설정하고, 정성적 및 정량적 평가를 실시하였다. 평가 결과, PDA를 활용한 교통사고 조사는 수기조사에 비해 자료의 정확성 및 편리성, 그리고 조사시간 측면에서 비교 우위에 있는 것으로 평가되었다. 그리고 사고데이터를 입력하는 형식에 관한 일부 개선이 필요한 면도 파악되었다. 향후 이러한 문제점을 개선한다면 사고조사 분야에 큰 기여를 할 것으로 판단된다.

A study was conducted on the preparation of Ramyon using composite flours of raked barley (20 or 30%)-wheat(80 or 70%) in commercial plant scale and on the quality evaluation of Ramyon made from those flours. The naked barley(20%)-wheat(80%) flour gave acceptable Ramyon-making characteristics during the continuous Ramyon manufacturing process. The composite flours had a higher water absorption rate in kneading process and oil absorption value of the Ramyon product than those of wheat flour alone. Even though the Ramyon of composite flours showed a little inferior value compared with wheat flour alone in the cooking and texture characteristics, sensory panel scores of Ramyon indicated that the naked barley (20%)-wheat(80%) flour was acceptable in Ramyon.

Because hand-written characters, especially drawn by a brush can give readers various impressions, they are not only a communication method but also art works. Authors have already investigated the relationship between brush motion analytical results and sensory testing results obtained from Japanese hiragana and reported quantitative evaluation method for the beauty of hiragana, In this paper, sensory tests for South Koreans who cannot recognize the word are carried out, compared with sensory testing results of Japanese. The evaluation objects are 6 hiragana drawn by 4 beginners and 2 experts, Semantic Differential Method based on 30 paired evaluation words are used in the sensory tests. Therefore South Koreans also feel the beauty in hiragana drawn by experts, as compared with by beginners. On the other hand it was confirmed that South Koreans couldnt recognize the difference among beginners. Judging from the factor analysis results, both Japanese and South Koreans selected stability as the 1st factor, there is interesting difference in the following orders.

A derivative based approach to process optimal design in powder forging is presented. The process model, the formulation for process optimal design, and the schemes for the evaluation of the design sensitivity, and an iterative procedure for the optimization are described in detail. The validity of the schemes for the evaluation of the design sensitivity is examined by performing numerical tests. The capability of the proposed approach to deal with diverse process parameters and objective functions is demonstrated through applications to some selected process design problems.

This paper addresses three central decision-making problems frequently encountered in developing evaluation checklists for ex-post evaluation of R&D projects at private R&D centers: 1) what kind of evaluation elements and factors should be included in the evaluation forms\ulcorner 2) how much weight should be assigned to each evaluation factor and element\ulcorner and 3) could the same evaluation elements and factors with weights be applied all the project type(research, development, and engineering)\ulcorner To answer these questions, we identified the evaluation elements/factors based on the review of relevant literature and measured the perceptions of researchers, R&D managers, and top managements of the three private R&D centers to get the information about the importance levels of the elements and the weights of the factors for each of the three project types. The findings include that 1) all the evaluation elements derived from the literature exhibited high importance levels, and 2) the importance levels of the elements and the weights of the factors were quite varied along the project types. Theoretical and practical implications of the findings for ex-post evaluation of R&D projects are discussed.
