박진희(Jinhee Park),배상훈(Sanghoon Bae) 한국비교과교육학회 2022 비교과교육연구 Vol.3 No.2
본 연구는 S대학의 디지털 배지 개발 사례를 통해 디지털 배지 활용과 비교과 프로그램 인증 및 다양한 이해관계자의 성찰을 제공하고자 한다. 연구방법으로는 문헌분석과 실행연구방법을 활용하였다. 연구결과 첫째, 문헌분석 결과 디지털 배지는 비교과 프로그램 참여율 향상과 질 관리 및 효과적인 인증 도구로 제시할 수 있다. 둘째, 디지털 배지 적용 정책은 대학에서 비교과 프로그램의 인증도구로 디지털 배지를 적용할 때 가장 중요하게 고려해야 할 점이다. 셋째, 디지털 배지 활용에 대한 내부 부서의 다양한 요구를 수용할 수 있도록 운영자 교육을 실시해야 한다. 넷째, 대학 내에서 비교과 프로그램 이수자를 대상으로 디지털 배지를 수여할 때 디지털 배지 간 차등을 두어 수여할 수 있는 전략을 제시할 필요가 있다. 다섯째, e-포트폴리오는 디지털 배지와 함께 비교과 프로그램을 비롯한 다양한 대학 경험에 대한 성취 인증 도구로서 활용될 수 있다. 이상의 결과를 종합해보면 대학에서 비교과 프로그램 인증을 위해 디지털 배지는 강력한 인증 도구로써 활용할 수 있는 가치가 있으며, 실제 적용 사례에서 보이는 다양한 이해관계자의 성찰을 통해 대학에서 적용되고 활용할 수 있는 가능성을 제시한다. This study aimed to elucidate the use of digital badges, certification of extra-curricular programs, and reflection of various stakeholders using the case of digital badges development at S University. Literature review and action research methods were used as research methods. The study results confirmed the following. First, the literature review affirmed that digital badges could be used as alternatives to improved participation in extra-curricular programs, quality management, and more effective accreditation tools. Second, the digital badge application policy must be primarily considered when applying digital badges as a means of accreditation to extra-curricular programs at universities. Third, the person in charge of digital badges in the university should consider various functions to accommodate various demands of internal departments. Fourth, digital badges must be issued with a price difference when issuing digital badges to students who completed extra-curricular programs. Fifth, the e-portfolios can be used to recognize the achievement of various university experiences, including extra-curricular programs and digital badges. Moreover, the results corroborated that digital badges can be employed as powerful accreditation tools to certify extra-curricular programs in universities and can be applied and utilized in universities by reflecting various stakeholders in practical application cases.

This study was performed to verify the spray characteristic of different driven injector in common-rail system. We developed the injector with needle driven by a piezo-electric material, called the piezo injector. The conventional solenoid injector have some limit to control the injection rate even if the common-rail injection system have a good flexibility to adjust the injection pressure and injection timing regardless of direct injection diesel engine's speed and load. To investigate the injection characteristics and needle behavior for different needle driving type of the high pressure common-rail injector, the test rig for injection rate measurement and spray experimental system were used. The injection rate was measured by using an injection rate meter based on the Bosch method. And the spray characteristics such as spray tip penetration, spray tip speed and spray angle were obtained by analyzing the sequential photographs of high speed spray. Results showed the rapid increase in the spray tip penetration was caused by the fast needle movement in piezo injector and rapid rising of injection rate at initial injection stage was observed.

1. CONTENTS (1) RESEARCH OBJECTIVES This study set out to stratify the characteristics of urban redevelopment projects in their stages and the major factors influencing them and provide improvement measures and implications applicable to actual districts of urban redevelopment projects along with their relative importance. (2) RESEARCH METHOD The factors affecting the environmental characteristics of urban redevelopment projects and the evaluation methodology on purchasing have been defined based on prior literature review. Based on which. the weights of factors in categorized level were determined based on the Analytic Hierarchy Process based on Expert Choice 2000 with Excel. (3) RESEARCH FINDING The analysis results show that the feasibility of project was the most important m the stage of basic project planning. Resident participation and reflection of residents' opinions scored considerably higher points in the stage of project planning and district selection. The appropriateness of consent request recorded the highest importance in the stage of application and approval of an association committee. The appropriateness of association director and representative election was the most important in the stage of application and approval of an association. Security and rent income was the most important in the stage of project implementation and approval. The appropriateness of additional allotments was the most important in the stage of management and disposal planning and completion. 2. RESULTS The study delved into the fundamental causes of conflicts in urban redevelopment projects and provided analytical implications and solutions applicable to actual project districts based on those evaluation factors.
텐저블 인터페이스 기반의 스마트 퍽 시스템에 적용되는 User 보안 인증 시스템 설계 및 구현

현재 국내는 4차산업이 활성화됨에 따라 디지털정보화 사회로 급속적인 발전을 이룩하였다. 이에 User들은 스마트 폰이나 태블릿 PC 등의 디바이스장치를 통해 새롭고 다양한 정보와 자료들을 획득 및 수집하고 있는 추세이다. 이렇게 다양한 콘텐츠와 서비스가 실시되고 있음에도 불구하고, User들의 요구는 점차적으로 극대화되고 있으며, 이를 충족하고자 TUI기반의 콘텐츠들이 우후죽순 생겨났으나 기존의 테이블 탑 디스플레이에 새로운 인터페이스인 스마트 퍽을 사용을 하는데 있어서 다수의 User가 동시에 접근을 하지 못하는 어려움이 있었다. 이에 대해 본 논문에서는 스마트 퍽 시스템에 User를 위한 보안인증 시스템을 구축하고 이를 통해 스마트 퍽에 대한 User를 구분하고 인증하는 시스템을 적용하였고, 다수의 User가 동시적으로 인터페이스에 접근 하였을 때, 발생되는 보안적인 문제점을 해결하였다. As the digital information society develops, services for providing mutual interfaces between various digital devices and users are being implemented. Therefore, users acquire and use a lot of information through various devices such as smart phone and tablet PC. It is a very common sight for a user to handle multiple devices in an interface. These user-oriented interfaces have gradually evolved from the existing methods and have developed new interfaces to the present. The TUI (Tangible User Interface) is a realistic interface technology that provides physical manipulation of digital information. It is an interactive interface that enables digital information to be applied to physical objects so that users can use them conveniently in daily life. In this study, we implemented a service that provides users with more various contents and additional elements by inter working with smart puck system using physical objects. User authentication using LEA (Lightweight - Encryption Algorithm) encryption algorithm, which has been researched and developed in Korea, so as not to cause a collision when accessing contents at the same time, The system was designed and constructed, user authentication was classified so that it could be applied to smart puck system after construction, and multiple users access the interface at the same time to solve the conflict problem.

배성문(Sung-Moon Bae),김정한(Jeong-Han Kim),조철우(Cheol-Woo Cho),정태준(Tae-Joon Jeong),육홍선(Hong-Sun Yook),변명우(Myung-Woo Byun),이승철(Seung-Cheol Lee) 한국식품영양과학회 2002 한국식품영양과학회지 Vol.31 No.2
감마선 조사가 왕겨, 미강, 맥강의 항산화능에 미치는 영향을 조사하기 위하여 4.2 kGy/h의 속도로 각각 5, 10, 15, 20kGy를 조사한 후, 메탄올 추출물을 제조하여 항산화능의 변화를 측정하였다. 감마선을 조사하지 않은 시료의 총 페놀함량을 측정한 결과, 왕겨가 0.873 mM, 미강이 0.643 mM, 맥강이 0.377 mM로 측정되었으며, 감마선 조사에 따른 총 페놀 함량은 조사선량에 상관없이 일정하게 유지되었다. 전자공 여능의 측정결과 감마선을 조사하지 않은 왕겨, 미강, 맥강에서 모두 비슷한 활성을 보였으며, 감마선을 조사한 경우에도 모든 시료에서 조사선량에 따른 유의적인 변화를 나타내지 않았다. TBARS분석에서는 감마선을 조사하지 않은 왕겨와 미강 추출물이 맥강 추출물보다 지질 과산화 억제력이 높았으며, 감마선 조사시에도 왕겨와 미강은 활성이 유지 또는 보유되었으나 맥강은 조사선량이 높을수록 지질의 산화 억제력이 상당히 감소되었다. 따라서 왕겨, 미강, 맥강의 페놀성분과 전자공여능에 관여하는 성분이 감마선에 매우 안정하며, 지질 과산화 억제능에 관여하는 성분은 왕겨와 미강의 경우에는 감마선에 안정하지만 맥강의 경우 불안정하였다. Effect of γ-irradiation to cereal processed by-products was examined for antioxidative ability. Rice hull (RH), rice bran (RB) and barley bran (BB) were irradiated with 5, 10, 15 and 20 kGy of γ-ray at 4.2 kGy/h. The amount of total phenol compounds of unirradiated RH, RB, and BB were 0.873 mM, 0.643 mM, and 0.377 mM, respectively. Irradiation up to 20 kGy did not show noticeable effect to the amount of total phenol compounds in RH, RB and BB. Electron donating abilities of RH, RB and BB were very similar, and they were not affected by irradiation. According to TBARS analyses, the inhibition abilities of lipid peroxidation of RH and RB were not affected by γ-irradiation, while those of BB were decreased with irradiation. These results indicate that BB is more sensitive to γ-irradiation than other rice processed by-products.
