The purpose of this study was to analyze the labeling of commercial protein bars in Korea and USA to develop Korean protein bars. Furthermore, we compared protein contents of products with daily protein intake, DRI, and AMDR. The protein bars were sampled in off- and on-line markets of both countries, with 17 in Korea and 113 in the US. As the results, since US products have bigger than one serving size than Korean ones, the intake of overall nutrients is higher, especially protein and sodium. Protein contents (per 100 g) of products in US were higher than those of Korea. The highest protein was soy protein isolate (SPI) in Korea and whey protein isolate (WPI) in the US. This is thought to be influenced by the preference and familiarity of food according to the country. In conclusion, since there are difference in eating habits, intake and preference of the protein source, it is necessary to develop suitable protein bars for Koreans. Therefore, this research provides the baseline of protein bars for consumers to choose products.

The wisdom contents consists of an ordinary person's ideas and experience. The Wisdom Market [1] is an online business model where wisdom contents are traded. Thus, the general public could do business activities in the Wisdom Market at ease. As the wisdom contents are themselves the thought of persons, there exists many similar or duplicated contents. Existing copyright protection schemes mainly focus on the primary author's right. Thus, it's not appropriate for protecting the contents of Collective Intelligence that requires to protect the rights of collaborators. There should exist a new method to be dynamic capable of combining and deleting rights of select collaborators. In this study, we propose collective copyright authentication scheme suitable for the contents of Collective Intelligence. The proposed scheme consists of collective copyright registration, addition and verification protocols. It could be applied to various business models that require to combine multiple rights of similar contents or to represent multiple authorships on the same contents.

This study was conducted to propose a product planning prediction model using logistic regression algorithm to predict seasonal factors and rapidly changing product trends. First, we collected unstructured data of consumers in portal sites and online markets using web crawling, and analyzed meaningful information about products through preprocessing for transformation of standardized data. The datasets of 11,200 were analyzed by Logistic Regression to analyze consumer satisfaction, frequency analysis, and advantages and disadvantages of products. The result of analysis showed that the satisfaction of consumers was 92% and the defective issues of products were confirmed through frequency analysis. The results of analysis on the use satisfaction, system efficiency, and system effectiveness items of the developed product planning prediction program showed that the satisfaction was high. Defective issues are very meaningful data in that they provide information necessary for quickly recognizing the current problem of products and establishing improvement strategies.

With the global pandemic of COVID-19, it is pointed out that exposure to false information to the public could cause serious problems. However, in pandemic situations, there is also an positive effect for the public to share private-led information rather than centralized unilateral delivery of information. This study analyzes the role of private-led information provision in infectious disease situations. To this end, topic modeling and sentiment analysis is carried out on online reviews of all COVID-19-related applications in Google Playstore provided by the Korean government and the private. The results showed that the user's evaluation of private apps, which were used from the early stage of COVID-19, was much higher than the apps provided by the government. In particular, users responded more positively to private apps than government apps in all aspects such as reliability of information, risk avoidance, timeliness, usefulness, and stability. Based on these results, a post-monitoring system is recommended rather than a pre-block of all private apps.

The importance of online marketing is emerging due to the prevalence of COVID-19. In order to respond to the changing business environment, we have collected ten years of sales data of SME bakery company that have experienced a decrease in sales due to the COVID-19. As a result of the analysis, we found that switching from offline markets to omnichannel B2B and B2C markets and taking 'small quantity batch production' to 'mass production in a small variety can improve management. This study presented online and offline marketing strategies through data analysis of small and medium-sized bakery companies, which have relatively insufficient digital capabilities compared to large companies, and could be a guideline for many SMEs.

In this study, based on an analysis of two DNA barcode markers (cytochrome c oxidase subunit I and cytochrome b genes), we performed species identification and monitored labeling compliance for 50 commercial pufferfish products sold in on-line markets in Korea. Using these barcode sequences as a query for species identification and phylogenetic analysis, we screened the GenBank database. A total of seven pufferfish species (Takifugu chinensis, T. pseudommus, T. xanthopterus, T. alboplumbeus, T. porphyreus, T. vermicularis, and Lagocephalus cheesemanii) were identified and we detected 35 products (70%) that were non-compliant with the corresponding label information. Moreover, the labels on 12 commercial products contained only the general common name (i.e., pufferfish), although not the scientific or Korean names for the 21 edible pufferfish species. Furthermore, the proportion of mislabeled highly processed products (n = 9, 81.8%) was higher than that of simply processed products (n = 26, 66.7%). With respect to the country of origin, the percentage of mislabeled Chinese products (n = 8, 80%) was higher than that of Korean products (n = 26, 66.7%). In addition, the market and dialect names of different pufferfish species were labeled only as Jolbok or Milbok, whereas two non-edible pufferfish species (T. vermicularis and T. pseudommus) were used in six commercial pufferfish products described as JolboK and Gumbok on their labels, which could be attributable to the complex classification system used for pufferfish. These monitoring results highlight the necessity to develop genetic methods that can be used to identify the 21 edible pufferfish species, as well as the need for regulatory monitoring of commercial pufferfish products.

The current study investigated the factors influencing the buyer's repurchase intention for second-hand products. This study first identified perceived risk and purchase value as the two primary influencing variables. Additionally, some exogenous variables influencing these two variables were examined. Statistical analysis using Partial Least Squares (PLS) revealed that product uncertainty, seller uncertainty, and site trust had statistically significant relationships with perceived transaction risk. However, while economic benefit showed a significant impact on purchase value, product scarcity and resale value did not exhibit a significant relationship with purchase value. Perceived transaction risk was found to have an insignificant relationship with repurchase intention, but indirectly influenced repurchase intention through purchase value. Purchase value was identified as having a significant influence on repurchase intention. Therefore, it was concluded that purchase value is the most important factor influencing repurchase intention in the purchase of second-hand products, while transaction risk indirectly influences repurchase intention through purchase value. The study indicates that product uncertainty and economic benefit are the most significant exogenous factors influencing transaction risk and purchase value, respectively.

최근의 웹을 기반으로 한 소셜 네트워크 서비스의 발전은 사회관계 형성 서비스를 넘어 광고 마케팅 및 SNS 오픈마켓 등의 상업적 이용으로까지 사용되고 있으며 Facebook Live와 같은 개인방송의 영역까지 확장되고 있다. 인터넷을 통한 온라인상의 사회관계는 노화와 질환으로 외출이 어려운 노년층에게 지역사회 및 친구들과의 의사소통을 가능하게 할 뿐만 아니라 인터넷을 통한 정보 활용으로 생활의 질을 향상시키고, 노후를 즐길 수 있는 방법을 찾는 데 도움을 줄 수 있다고 알려져 있다. 하지만 대부분의 웹서비스는 복잡한 사용자 인터페이스를 제공하고 있으며 익숙하지 않은 기기를 사용하는 것은 노년층에게 쉽지 않기 때문에 노년층은 제한된 콘텐츠만을 제공받게 되어 정보화 사회에서 소외될 가능성이 있다. 이에 본 논문에서는 웹 접근성을 향상시킨 소셜 콘텐츠 서비스 Photo Alive! Demo EasyFace를 소개한다. 또한 노년층이 다루기 어려웠던 키보드와 마우스를 벗어나 새로운 조작 기기들로 웹 서비스를 이용할 수 있도록 구현하였다. MINIX Remote Control, Mirroring, EasyFace Control Application 세 가지의 조작기기 작동 방법을 구현하여 노년층에 맞춤화 된 새로운 사용자 인터페이스를 제안하고자 한다.

1990년대 중반이후 정보통신의 발달에 의한 인터넷의 활용이 전세계적으로 급속히 팽창하면서 사이버마켓이라는 새로운 시장형태하에서 전자상거래가 급속히 성장하고 있다. 인터넷 전자상거래의 성장은 기존의 유통구조를 오프라인으로부터 온라인으로 전환시키고 물류체계까지 변화시키고 있다. 전자상거래의 경우 인터넷과 같은 정보시스템의 발달에 의해 독자적으로 성장할 수 있는 것은 아니며, 실제거래를 위한 물류와 연계해서만이 가능하다. 따라서 전자상거래의 급속한 성장과 더불어 문전배송서비스(door-to-door delivery service)가 가능한 택배서비스가 급속히 증가하고 있다. 이러한 관점에서 도시내에서의 전자상거래에 의한 택배서비스시장 환경변화를 고려하여 전자상거래를 촉진시키는 어떤 요인이 택배서비스에 영향을 미치고 성장에 중요한 역할을 하는지를 파악해 보는 것도 흥미있는 일이라 하겠다. 본 연구는 시계열데이터를 이용하여 전자상거래에 의한 택배서비스시장의 상관관계를 검토하고 전자에 의한 후자의 성장요인을 분석해 보는데 그 목적이 있다. 본 연구에서는 택배서비스시장의 성장요인을 시장내부의 내적요인과 외부의 외적요인으로 구분하고, 외적요인을 다시 교통요인과 사회경제적 요인으로 구분하여 전자상거래를 사회경제적 요인으로 간주하였다. 그리고 이 사회경제적 요인으로서의 전자상거래에 의한 택배서비스시장의 인과관계성을 그랜저-심즈(Granger-Sims) 인과관계검정을 이용하여 분석하였다. 분석결과, 한국의 전자상거래는 EDI(전자문서교환)도입업체수, 인터넷 쇼핑몰수, 인터넷 이용자수, 전자상거래를 위한 법제도 체계 등의 증가에 의해 촉진되었으며, 이에 따라 택배서비스시장도 성장한 것으로 나타났다. 특히 정부주도에 의한 정보화추진이 전자상거래를 촉진시켜 택배서비스시장에 영향을 미친 것으로 분석되었다.
