This study analyzed the cases of three teacher communities participating in an innovative professional development program and clarified the characteristics and the process of lessons for mathematics-oriented convergence that were developed and applied during the program. Each of the teacher communities designed and implemented lessons according to the context of each community and the concept of lessons for mathematics-oriented convergence were developed and refined. The lessons developed by the three teacher communities were characterized as convergence problem posing lessons using technology, convergence of various subject content focused on mathematical concepts through team teaching, and convergence lessons according to students' achievement levels. The program contributed to teacher community activities by proving sustainable professional development in the area of convergence education, a connection between the content of their professional development and the context of the field, and opportunities for active participation in the process of developing and implementing the convergence lessons.

본 연구는 유기물 멀칭재 종류에 따른 토양수분함량과 동자꽃의 생육반응을 비교·분석하여 저관리 옥상녹화에서 멀칭재의 효용성을 알아보고자 수행하였다. 실험구는 멀칭재를 사용하지 않은 대조구 (Cont.; Control)와 코코칩 (C.O; Cocochip), 우드칩 (W.O; Woodchip), 짚거적 (S.T; Straw), 톱밥 (S.A; Sawdust) 등, 총 5개의 처리구로 조성하였다. 실험결과, 유기물 멀칭재 유형에 따른 토양수분함량은 W.O > S.T > Cont. > C.O > S.A 순으로 높게 나타났으며, 특히 톱밥에서 유의적 차이를 보였다. 생육 측정 결과, 초장에서 S.T > Cont. > C.O > W.O > S.A의 순으로 생육이 좋았으며, 초장을 제외한 다른 생육항목에서의 멀칭재별 유의적인 차이는 미미하였다. 상대엽록소함량과 체내수분량은 모두 무처리구보다 우수하게 나타나 유기 멀칭재 처리가 동자꽃의 엽록소함량 및 체내수분량 유지에 효과적인 것으로 판단된다. 특히 실험구 내 토양수분함량은 멀칭재 자체의 성질에 의해 영향을 받는 것으로 나타나 저관리 옥상녹화에서 각 식물의 특성에 적합한 멀칭재 사용이 요구되며 수분 스트레스에 약한 수종 선정 시 유기물 멀칭을 통해 극복할 수 있을 것으로 판단된다.

$Ni_{0.79}Co_{0.15-x}Cu_xMn_{2.06}O_4$ ($0{\leq}x{\leq}0.09$) thick films were fabricated using the conventional solid-state reaction method and screen-printing method. Structural and electrical properties of specimens based on the amount of Cu were observed in order to investigate their applicability in the infrared detector. All specimens showed a single spinel phase with a homogeneous cubic structure. As the amount of Cu increased, the average grain size increased and was found to be approximately $5.01{\mu}m$ for the $Ni_{0.79}Co_{0.06}Cu_{0.09}Mn_{2.06}O_4$ specimen. The thickness of all specimens was approximately $55{\sim}56{\mu}m$. As Cu content increased, the resistivity and TCR properties at room temperature decreased, and these values for the $Ni_{0.79}Co_{0.06}Cu_{0.09}Mn_{2.06}O_4$ specimen were $502{\Omega}-cm$ and $-3.32%/^{\circ}C$, respectively. The responsivity and noise properties decreased with an increase in Cu content, with the specimen with a Cu content of x=0.09 showing 0.0183 V/W and $5.21{\times}10^{-5}V$, respectively.

A hologram projects a 3 dimensional video as same as a real subject and it is made by principles of holography. Many researches about holographic technology have been developed. Studies for visualization of 3D videos, holographic storages, and optical media have proceeded mostly in engineering. It is hard to find any researches about the convergent system from the viewpoint of interactive elements and motion graphic design such as this paper's concept. Most studies of augmented reality have been developed in the domain of technology and education but the field of content production. AR has been convergent with various fields and media, so it is time to make an active progress in the study of convergent content development. The goal of this study is to develop cultural contents and create new values through the convergence of holography and AR. The purpose of this paper is to propose the way of developing the convergent type of cultural contents and construct the production system by the new approach to users using the convergence technology of holography and augmented reality.

The effect of pan frying method was evaluated for proximate composition of selected fish species Pampus argenteus, Lethrinus nebulosus and Acanthopagarus arabicus which were determined by standard procedures. Proximate compositions found in the frying fillets were different to the raw fish samples. The moisture content seems to decrease in all fried samples. The reason of moisture loss at the time of frying produced is excessive protein amount in fried fish as compare to raw fish. Protein content seemed to increase in Pampus argentus > Lethrinus nebulosus and >Acanthopagrus arabicus in their particular fried form. The outcomes shown that protein content was in the ranges of 14.83-25.07 g/100g in fried samples, while the fat content was between 3.76-9.77 g/100 g. The energy content was the highest in the fried fish Lethrinus nebulosus (236 kcal/100 g), Pampus argentus (161 kcal/100 g) and Acanthopagrus arabicus (135 kcal/100 g). The information achieved in this study would be very important to fish consumers, processors and nutritionists to academically increase their awareness regarding the nutrients contents in selected fish species.

Upbringing requires an active intervention in the process of children growing up. Convergence in technology and media makes it possible to augment nurturing by making blended infrastructures with new digital resources available in learning environments at schools. A game-based provision of educationally-valuable content within a collective, virtual environment combined with an analysis of events in the game after it has been played (blended nurture environment) may help to better communicate human values especially where old-fashioned discussion methods fail or do not fulfill the promise of effective, educational institution-based methods of bringing up. This is where life sciences, psychology, media, pedagogy and technology (need to) converge.

A fiber diffuser sheet based on poly (ethylene naphthalate) (PEN) and poly (methylpentene) (PMP) has shown potential for liquid crystal display backlight units, but these materials have an interfacial adhesion problem. To improve the interfacial adhesion between the fibers and matrix components, we have proposed the use of amorphous poly (cyclohexane-1,4-dimethylene terephthalate) (Tritan) instead of PEN. Furthermore, the fabrication processes have been optimized and simplified to improve the optical and mechanical properties of the sheet. As a result, the most effective fiber content for achieving the best haze characteristics of a sample consisting of Tritan and PMP has been identified.

This study aims to understand the importance of commercialization of research and development projects and examines key factors that allow successful technology transfer and commercialization. Given the characteristics of the railway research project, and assuming that R&D input factors would vary depending on the technology readiness level and the degree of research convergence, this study analyzes the moderating effect of each R&D input factor on technology transfer and commercialization to determine their eventual impact. Through this study, it was found that it was necessary to proceed to technology transfer and commercialization of the national research and development projects via strategic workforce composition and allocation of research funding given the subjects and development goals of R&D projects.
