We measured the magnetic properties of stainless steels type 304 and 316L to see if those materials can be used for the applications where non-magnetic materials are required. The results show that the relative permeability of samples was greatly increased during manufacturing processes. After full solution annealing, however the permeability could be reduced to less than 1.02. Thus, the materials may be employed in the low-permeability applications.

한국어 교육 콘텐츠 '스즈키가의 한국어 대모험' 일본 진출, PDA 전시가이드 솔루션 독일 괴테하우스 상용서비스 등 해외에서 더 인정받는 기업 멀티화인테크(www.mft.co.kr). "스즈키가의 한국어 대모험을 제작하기까지 8억원을 투자하는 등 기술 및 콘텐츠 개발에 투자를 아끼지 않고 보낸 5년이다. 투자비를 벌기 위해 EBS, 대한교과서, YMCA 등으로부터 의뢰받은 콘텐츠를 만들어야 했다. 60%는 외주용역 콘텐츠 제작에, 40%는 자체 브랜드 개발을 위한 개발에 밤샘을 마다하지 않았던 시간이다." 현재 동국대 영상제작과 교수이기도 한 멀티화인테크의 김재봉(42) 사장은 "비지니스보다 강단에서 학생들을 가르치는 것이 더 좋겠다고 생각한 적이 있는데, 투자에 대한 결과가 눈에 보이는 요즘은 시간이 어떻게 가는 줄 모르겠다"며 사업 재미에 푹 빠져 있다고 말한다.

We introduced and compared the two methods, 'figure-8 coil method' and 's-parameter method', to measure high frequency permeability of magnetic films. We made a permeameter by using s-parameter method and discussed about problems and solutions in measuring permeability. We can measure the permeability rapidly and exactly up to 200 MHz with the aid of computer program and the low level permeance detection limit is about $1\mu\textrm{m}$.

This study evaluates the extent to which the government's financial support policy, the Audio-visual investment fund, contributed to raising capital for Korean films. Audio-visual investment fund in the Korean film industry, which has been formed through the public sector support since 1999. The Audio-visual investment fund is a leading financial support policy for the Korean film industry, and began with the investment of the Small and Medium Business Administration and the Korean Film Council. It has become an important source of Korean film production costs and has spread to other cultural industry sectors, as a way of capital procurement for a start-up companies and cultural projects. This study reconstruct the data of the organizations such as the size of a new investment fund by public sector, the ratio of public capital contribution, the amount and number of investment in Korean films, investment multiplier compared to equity investment, and the internal return rate(IRR) of liquidation funds in the Korean film capital market from 1999 to 2017. The purpose of this project was to provide the basis for assessing the achievements of the Audio-visual investment fund policy in contributing to the growth of the film industry.

Recently, crowdfunding platforms have received attention as one of the content investment platforms for the public. This research attempts to explore the influencing factors on the success of movie euqity crowdfunding project. We use 'number of texts', 'number of images', 'star influence power', 'IP-based movie project', 'movie production stage', 'box office prediction', 'investment capital ratio', 'amount of surplus available investment', 'profit calculation method' and 'minimum investment amount' as independent variables. And we examined how these factors affects the achievement rate of movie crowdfunding. As a result of multiple regression analysis, 'movie production stage', 'investment capital ratio', 'amount of surplus available investment' and 'profit calculation method' have a significant effect on the crowdfunding achievement rate. In addition, the results of this research can be used for reference when planning film crowdfunding projects.

In this paper, an embedded EM sensor was researched to estimate prestressing force of PS tendon in PSC girder. Recent methodologies for managing prestressing force loss were staying on verifying a applying prestressing force under construction, namely the loss management can not be controlled after construction. To estimate the tensile force of PS tendon during lifetime of PSC girder, this research proposed a bobbin-type embedded EM sensor that can be embedded in PSC girder is designed and fabricated considering the shape properties of anchorage zone and sheath. To verify the proposed sensor, a small PSC girder test was performed. The embedded EM sensor was connected to a sheath and anchor block, and the concrete was poured. After curing, the change of the permeability of PS tendon under tensile forces of 200, 710, 1070, 1300kN was measured using embedded EM sensor. The permeability of PS tendon had decreased according to the increment of applied tensile force. Also it is confirmed that the change of permeability due to applied tensile force could resolve the applied tensile force values. As a result, proposed embedded EM sensor could be embed into the PSC girder and it could be used to estimate the tensile force variation during lifetime of PSC girder.

이 연구는 실천적 차원에서 방송콘텐츠 제작산업을 활성화시키기 위한 세제혜택의 개선방안을 다루었다. 콘텐츠 제작규모가 커짐에 따라, 투자를 얼마나 유치할 수 있는지가 콘텐츠의 질을 결정하는 데 중요한 요인으로 작용하고 있다. 중소기업 대상 지원정책이나 벤처기업 지원정책 등이 방송콘텐츠 제작산업에도 적용될 수 있지만, 방송콘텐츠 산업의 특성상 실질적인 혜택이 거의 없는 것이 현실이다. 영상콘텐츠제작관련 세제혜택이 있지만 드라마, 애니메이션 등 일부 장르에 국한되어 있다. 이 연구는 관련정책의 개선이 필요함을 주장하고, 제도의 개선안을 제시한다.

In order to accelerate the development of the Film Industry of Korea it is quite necessary to evaluate the value of Film Production Company appropriately and then to activate investment through its work of estimating. So far however, the researches on the evaluation model for Korean Film Production Company has been rarely conducted considering those of any other advanced countries. Therefore, the appropriate valuation model among numerous valuation model for film firms has not been provided until now. So the purpose of this article is to suggest the rational decision making criteria for the investment of Film Production Company by comparing with DCF, FCF, and ROV model through the empirical research focused on case study. According to the results of research, ROV model is more efficient and available comparing other two methods.

고투자율비정질금속자성재료는 원자비가 종래의 고투자율금속자성료보다도 싸고, 제조공정도 간단하게 될 가능성이 있기 때문에 낮은 가격으로도 제작할 수 있는 가능성이 있다. 자기특성에 관해서는 주규소강판에 비하여 포화자속밀도는 낮지만 철손이 상당히 작은 특징이 있으며 퍼말로이에 비해서는 훨씬 높은 투자율 및 포화자속밀도를 갖는다. 따라선 싼값으로 공급된다면 재래의 재료에 대치될 가능성이 커지게 된다. 이미 구미에서는 전자기기용자심 뿐만 아니라 배전용변압기의 철심으로서 실용화가 진행되고 있다. 기계적특성에서도 강도가 현저히 높고, 인성이 풍부하여, 내마모성이 뛰어나다. 이러한 특성과 자기특성을 함께 살린 응용면으로서 자기헤드, 재료, 자기차폐재료 등을 들 수 가 있다. 이상은 고투자율비창질금속자성재료의 실용화와 관련된 유리한 측면인데, 이 재료는 본질적으로 불안저이평횡상태에 있기 때문에, 자기적 및 기계적 특성이 열적으로 불안정하다고 하는 큰 난점을 가지고 있다. 물론 이러한 열적특성을 적극적으로 활용하는 면도 생각되지만, 이 문제는 실용화를 위해서는 큰 방벽이라고 할 수 있을 것이다.
