This study was performed to evaluate the sodium and potassium content of the 19 kinds of side dish purchased from traditional market and super market in Daejeon area. The results are summarized as follows. Sodium content(mg/100 g) among samples was the highest in the Jangachies. The sodium contents of Yeongeun jorim, Bellflower saengchae, Kkaetip jangachies, Chonggak kimchi, Changranjut in super market were significantly higher than those of the traditional market (p<0.05). On the other hand, the sodium contents of the other side dishes in traditional market were significantly higher those in super market. These results suggested that the sodium content of side dishes in the traditional market were higher than those in the super market. Sodium intake from Kimchi and Jangachies per one serving size is estimated significantly highest among samples. Also, potassium content of side dishes were low detected compare to sodium content and potassium content of side dishes in the traditional market were higher than those in the super market. From these results, it was suggested that food labeling (Na content) on the package of side dishes is to be required for lowering Na intake, and standard cooking methods is to be established.

NFTs, which guarantee ownership of digital files using blockchain technology, are the new field for the content industry. The NFT provided new opportunities for content creators to trade digital contents without going through mediation freely. Additionally, collectors and investors can safely and easily own their works without the threat of illegal copies. However, since only a limited number of content creators are participating in the NFT market, there needs to be an influx of various content creators and a process of popularization for this market to grow and develop into the main stage. Furthermore, research on NFT has been limited, and understanding the drivers of creators choosing to participate in NFT is insufficient. Thus, this study aims to identify the factors affecting content creators participating in NFT by applying a mixed-methods approach and presenting practical implications. Using topic modeling and in-depth interviews, this study derives the positive and negative factors and suggests strategies to activate content creators' participation in the NFT market. Through this, we can guide that management implication to reduce the risks and costs of participating in NFTs is needed to encourage the participation of creators. It will also provide insight into ways to develop the NFT content market.

디지털 기술과 정보통신망의 발달로 인하여 다매체-다채널이 등장함에 따라 방송콘텐츠시장의 유통경로가 더욱 다원화 되고 있다. 본 연구에서는 온라인 방송콘텐츠 다운로드 시장을 중심으로 온라인 방송콘텐츠 시장의 문제점을 해결하는데 중요한 역할을 담당하고 있는 콘텐츠 유통 중개업자(Master Contents Provider, MCP)의 핵심 역량차원과 유통구조개선 효과간의 관계를 사례연구를 통해 규명하고자 하였다. MCP의 핵심 역량은 자원기반이론(Resource_based theory)을 조사하여 물적, 재무, 인적, 기술, 무형 및 조직자원으로 도출하였으며, 6개 자원중심으로 MCP의 핵심 역량에 대한 사례조사를 수행하였다. 사례연구 결과, 온라인 방송콘텐츠 다운로드 시장의 문제점은 불법거래 및 저작권 침해, 지상파 방송사업자와 웹하드 서비스업체 간의 직접거래로 인한 거래비용증가, 방송콘텐츠 서비스 품질 하락, 온라인 방송콘텐츠 다운로드 시장의 파편화 등으로 규명되었다. MCP의 물적, 재무, 기술, 인적, 무형 및 조직자원이 결합된 MCP의 핵심 역량이 온라인 방송콘텐츠 다운로드 시장의 문제점을 해결하여 유통시장의 효율성 및 투명성을 제고하고, 유통구조를 통합하며, 나아가 지상파 방송사업자와 웹하드 서비스업체의 매출 증대에 크게 기여하고 있는 것으로 나타났다.

In recent years, the number of digital content transaction has increased dramatically, in main, owing to the innovation of IT technology. At the same time, it creates new problems which have never been found in traditional transactions. Especially, due to the easy-copy characteristics of digital content, the illegal usage of digital content proliferates. Also the conflicts between seller an d buyer in digital content transactions on cyberspace market take place frequently because contracts were made without face-to-face discussion. The increase of illegal usage and conflict in digital content market would diminish motivation of creators for their work, furthermore break down digital content market on cyberspace. Digital content transaction authentication system would play an important role in creating sound digital content market. Especially, it would make big contribution to reducing the number of conflict between seller and buyer. In this context, the main objective of this study is to suggest operational model of digital content transaction authentication and to explain critical success factors in organizing digital content transaction authentication system.

Purpose - This study aims to examine the incremental information content of cash flw from operations and earnings in the Iranian capital market. Design, methodology, and approach - Based on market-based accounting research, this study uses statistical associations between accounting data (earnings and cash flw) and stock returns to assess/measure the incremental information content (value relevance) of cash flw and earnings. A multivariate regression model based on panel data is used to examine the incremental information content of earnings and cash flow from operations. Results - The results show that both earnings and cash flow from operations have incremental information content beyond each other. These results are consistent with the findings of recent studies. Overall, the fidings of this study support the usefulness of cash flw information in addition to earnings, in fim valuation by investors in the Iranian market. Conclusions - The study makes the following contributions to the Iranian literature on incremental information content of cash flw and earnings. First, this study employs actual cash flw data derived from cash flw statements. Second, this study employs a large sample size for a more recent period.

4차 산업혁명시대에 접어들면서 기존의 콘텐츠 제공 업체에만 의존했던 디지털콘텐츠 시장이 유투브와 같이 사용자의 참여로 다양한 디지털콘텐츠를 제공하고 있다. 이로 인해 디지털콘텐츠 시장의 활성화를 가져왔지만, 저작자의 저작권과 콘텐츠의 무분별한 도용 및 사용으로 디지털콘텐츠 시장에 악영향을 미치고 있다. 본 논문은 디지털콘텐츠를 보호하고 저작자의 저작권을 보호하기 위해 블록체인 기술을 기반으로 디지털콘텐츠 관리 기술을 연구하였다. 제안 기술은 디지털콘텐츠와 저작권자를 보호하고 사용자를 식별하여 무분별한 디지털콘텐츠 접근과 도용을 방지한다. 디지털콘텐츠의 안전한 관리를 위해 블록체인의 인증기술로 활용되는 해쉬 함수를 활용하여 사용자를 인증하고 디지털콘텐츠를 관리하여 무결성과 인증 서비스를 제공한다.

The study aims to investigate the process employed by companies to intentionally create market categories through implementation of product strategy. Much of the research on market category formation focuses on the spontaneous emergence of market categories, with a few studies focusing on the intentional creation of market categories. In the course of this study, I therefore sought to understand the logic by which companies intentionally create market categories, by treating the process through which market categories are formed as a sensemaking process, and by treating the behavior of a company intentionally forming a market category as an effort to manage this sensemaking process. In empirical study, we conducted an exploratory case analysis through content analysis of company press releases and consumer reviews. It is possible that market categories can be formed or changed if the way in which they are shared among market participants can be changed. In this study, we identified two sense-giving activities for the creation of market categories by firms as follows: (1) reorganizing market categories that flat-panel TV manufacturers in the North American market have attempted to form into subcategories of smart TVs, and (2) connecting them to surrounding categories through strategic labeling to establish new categories.

Various types of media services are emerging due to the development of Internet and digital media production and distribution technologies. Various DRM technologies are being developed to prevent illegal copying of media contents and to protect the rights of content creators. There is a problem that the DRM provider and the content service provider must provide services in a mutually dependent manner through individual contracts. In this paper, we propose a cloud-based DRM market system which can be used only by content service providers when necessary for various DRM. The DRM market system is expected to show the effect of service activation for related small and medium sized companies by providing an interface that satisfies the requirements of DRM providers and contents service providers by using multi DRM technology.
