지금까지 이러닝 콘텐츠 개발의 대가 기준은 실제 이러닝 산업의 특성을 반영하지 않은 채 기존의 유사한 산업의 산정표나 가이드라인에 따라 산정되어 왔다. IT와 교육이 융합된 이러닝 산업에서 콘텐츠 개발 대가 기준의 부재는 이러닝 산업을 이끌어 가는 기업들에게 큰 애로사항으로 인식되어 왔다. 이러닝 산업의 특성을 반영하지 못한 개발 대가의 산정은 콘텐츠의 품질에 큰 영향을 끼치고 있으며, 이는 이러닝 산업의 성장과 발전을 저해하는 요인이다. 이러한 문제를 해결하기 위해, 본 연구에서는 이러닝 산업의 특성을 고려한 이러닝 콘텐츠 개발에 적합한 대가 기준을 제시하였다. 본문에서는 이러닝 산업의 콘텐츠 개발 대가 기준 책정에 대한 문제점과 그 특성을 분석하고, 기존의 대가 기준 산정 방식을 응용하여 이러닝 산업을 위한 콘텐츠 개발 대가 기준을 분류하고 정의하였다. 발주기관의 설문조사를 통해 이러닝 산업의 특성을 반영한 개발 대가 기준의 산정과 콘텐츠 개발 대가 기준 산정에 필요한 연구 방법론을 제시하여 이러닝 산업의 발전과 콘텐츠의 품질 향상에 기여할 수 있는 정책을 마련하고, 실질적으로 반영하여 사용함으로써 이러닝 산업이 보다 발전할 수 있을 것으로 기대한다.

The advance of All-IP digital convergence is now triggering fundamental changes in the media industry. This article analyzes the evolution of the media industry based on a value chain model, with a special emphasis placed on the impact of digital technology on the structure of media production, distribution, and consumption. As the Internet has evolved into an access channel for all forms of media, the boundaries of the media industry remain unclear and open thus enabling anyone to become a creator of media. Furthermore, the scope of media continues to become more dynamic as competition grows between older and more innovative forms of media. In this light, adapting to innovative technologies and more effectively meeting the needs of customers represent key factors for the continued evolution of the media.

Domestic digital signage industry has been growing in line with the Internet and intelligent devices like smart phones. However, policies for digital signage need to be supplemented because existing policies are only focused on regulations for outdoor advertisements. Moreover, while digital technologies have been developed, there are few contents technologies to support the digital technologies. In this context, this research aims to identify the problems in relation to the domestic digital signage industry and seek for measures to solve the problems. Various case studies and literature review were conducted to identify problems in terms of policy, technology and service, and measures for revitalizing the digital signage industry were suggested. The research is expected to help digital signage to serve as new convergence media available for customization targeting and user participation.

Automatic production systems are constantly advancing technologies to improve productivity and safety. Specifically, liquid filling machines are primarily utilized to package products into drums after manufacturing process in the hazardous chemical industry. Most existing filling machines allow the operator to open the drum cap and inject the product directly or semi-automation. In this study, we have developed a cap opening and closing mechanism onto the existing drum filling machine, enabling automatic and safe cap manipulation while filling the product in the IBC tank. By applying the appropriate torque value through numerical analysis, we confirmed that the system worked without any problems during the process of opening and closing the cap. Therefore, it is expected that the developed machine will give more production and reduce human efforts without risk in the chemical packaging industry.

오늘날 세계는 네 번째 산업혁명을 일으킬 신기술의 시대를 맞이하였고, 이는 'Industry 4.0'으로 통한다. Industry 4.0은 산업을 구성하는 다양한 요소가 서로 의사소통을 할 수 있는 스마트 체인을 구축하는데 기반을 두기 때문에 경제, 사회, 기술, 법률 등 다양한 측면에서 높은 불확실성이 존재한다. 위와 같은 사실을 바탕으로 본 논문에서는 Industry 4.0의 기본개념 수립 및 기능수행 시 발생하는 부정적 측면을 최소화시키기 위하여 선행연구자들의 연구를 바탕으로 한국 중소제조기업의 대응방안을 찾기 위한 연구를 하였다. 그 결과 Industry 4.0의 불확실성을 다양한 측면에서 정확하게 파악하고 대처하기 위한 노력을 한다면, Industry 4.0의 심장부에 해당하는 스마트 공장을 통해 기업의 영업이익 증대 및 국가의 경제성장을 이루는데 도움이 될 것이다.

A total of 6,973 steer growth records of Hanwoo breeding bull's progeny test data collected from 1989 to 2015 were analyzed to identify the most appropriate growth curve among three growth curve models (Gompertz, Logistic and von Bertalanffy). The Gompertz growth curve model equation was $W_t=990.5e^{{-2.7479e}^{-0.00241t}}$, the Logistic growth curve model equation was $W_t=772(1+8.3314e^{-0.00475t})^{-1}$, and the von Bertalanffy growth curve model equation was $W_t=1,196.4(1-0.646e^{-0.00162t})^3$. The Gompertz model parameters A, b, and k were estimated to be $990.5{\pm}10.27$, $2.7479{\pm}0.0068$, and $0.00241{\pm}0.000028$, respectively. The inflection point age was estimated to be 421 days and the weight of inflection point was 365.3 kg. The Logistic model parameters A, b, and k were estimated to be $772.0{\pm}4.12$, $8.3314{\pm}0.0453$, and $0.00475{\pm}0.000033$, respectively. The inflection point age was estimated to be 445 days and the weight of inflection point was 385.0 kg. The von Bertalanffy model parameters A, b, and k were estimated to be $1196.4{\pm}18.39$, $0.646{\pm}0.0010$, and $0.00162{\pm}0.000027$, respectively. The inflection point age was estimated to be 405 days and the weight of inflection point was 352.0 kg. Mature body weight of the von Bertalanffy model was 1196.4 kg, the Gompertz model was 990.5 kg, and the Logistic model was 772.0 kg. The difference between actual and estimated weights was similar in the Logistic model and the von Bertalanffy model. The difference between market weight and estimated market weight was the lowest in the Gompertz model. The growth curve using the von Bertalanffy model showed the lowest mean square error.
