This research was conducted to evaluate quality changes in traditional Doenjang and manufactured Doenjang during a storage period of 8 weeks. Low-salt Doenjang and commercial Doenjang were purchased from different manufacturers and proximate analysis as well as changes in isoflavone, polyphenol, flavonoid contents of the samples were investigated using a mass spectrophotometer. The salinity of traditional Doenjang, low salt Doenjang, and commercial Doenjang were $13.2{\pm}1.15$, $7.17{\pm}2.74$, $10.67{\pm}0.35%$, respectively and the salt concentrations of the soybean pastes did not change during storage. After 8 weeks at $35^{\circ}C$, chromatic values of all the paste samples decreased somewhat, with traditional Doenjang exhibiting fewer changes as compared to manufactured Doenjang. Amino acid nitrogen, acidity, microbial population all tended to increase with time, although some samples showed fluctuations during the test period. Moreover, the total isoflavone contents of traditional Doenjang increased with storage time while that of manufactured Doenjang tended to decrease. The isoflavone aglycone was shown to be the highest in traditional Doenjang, while isoflavone glycoside was abundant in manufactured Doenjang. Total flavonoid contents showed similar trends regardless of samples; initial contents of total flavonoid was 0.6 mg/g which increased to more than twice to 1.4 mg/g at the end of storage period. Composition profile of Doenjang extracts was analyzed using UPLC-Q-ToF.

Business Process Change(BPC) is regarded as a salient factor to improve an organizations` efficiency in the current fast-changing business environment. Despite the tremendous popularity and great potential, the field of BPC adoption is littered with remarkable failures. Consequently, there have been many studies that have tried to identify the environmental factors that lead to successful BPC. However, most of them have not considered the effect of the interaction between the environmental factors on BPC success. According to Klempa(1995), the fit between environmental factors of a company may have the impact on its BPC success. Under this background, this paper empirically examines the effects of the fit between the type of BPC and the organization`s culture on the success of BPC. Organization`s cultures, organizational learning, as well as knowledge sharing are the dominant causes that have impact on the innovation characters of organization. Whether an organization has safety-oriented homogeneous culture or it has the change-oriented heterogeneous culture may have impact on its implementation of BPC. Also the implementation of BPC may be affected by whether the organization adopts the improvement project which accompanies only small changes or it adopts the innovation project which leads to critical changes. Thus, we analyzed the effect of the fit between the organization`s culture and its BPC type on BPC success by using the survey data collected from the companies that have adopted BPC. The findings presented in this paper show that the organization having heterogeneous culture practicing innovation project and the organization having homogeneous culture practicing the improvement project resulted in the excellent BPC success.

With emergence of Internet, social media, and mobile service, the consumers have actively presented their opinions and sentiment, and then it is spreading out real time as well. The user-generated text data on the Internet and social media is not only the communication text among the users but also the valuable resource to be analyzed for knowing the users' intent and sentiment. In special, economic participants have strongly asked that the social big data and its' analytics supports to recognize and forecast the economic trend in future. In this regard, the governments and the businesses are trying to apply the social big data into making the social and economic solutions. Therefore, this study aims to reveal the capability of social big data analysis for the economic use. The research proposed a social big data analysis model and an online consumer sentiment index. To test the model and index, the researchers developed an economic survey ontology, defined a sentiment dictionary for sentiment analysis, conducted classification and sentiment analysis, and calculated the online consumer sentiment index. In addition, the online consumer sentiment index was compared and validated with the composite consumer survey index of the Bank of Korea. 인터넷, 소셜미디어, 모바일 등의 등장이후 소비자들은 개인의 의견을 온라인을 통해 적극적으로 표명하기 시작했고 이의 확산 또한 실시간으로 이루어지고 있다. 인터넷 기반의 다양한 커뮤니케이션 활동들을 통해 생산되는 텍스트는 인터넷을 사용하는 사용자들이 공유하고 공감하는 자원으로서 단순한 소통의 도구를 넘어 분석의 가치가 있는 새로운 정보의 창고가 되고 있다. 세계 각국의 정부와 기업은 인터넷과 소셜미디어를 통해 생산되는 소셜 빅데이터를 활용하여 사회/경제적 문제의 해결과 정부의 정책을 효과적으로 추진하는데 적극 활용하고 있다. 특히 경제와 관련해서는 경기현황에 대한 경제주체들의 움직임을 보다 빠르고 정확하게 분석하고 예측하여 이에 알맞은 정책을 적기에 실시할 수 있도록 다각적인 활동을 펼치고 있다. 본 연구에서는 소셜 미디어에 내재된 소비자의 직적접이고 즉시성 있는 의견을 경제적 측면에서 활용할 수 있는 온라인 소비자감성지수 모형을 제시하고 구현하였다. 이를 위해 한국은행의 소비자동향조사(CSI)와 소비자심리지수(CCSI)를 온라인으로 수행할 수 있는 어휘분류체계(온톨로지)와 감성사전을 구축하고 감성분석을 실시하여 생활형편, 경제상황, 소비와 수입 4가지 영역의 소셜감성지수를 도출하였다. 또한 이들을 결합한 온라인 소비자감성지수(e-CCSI)를 개발하고 소비자심리지수와 비교를 통해 유용성을 확인하였다.

마스터데이터관리 이해도가 국방 마스터데이터관리시스템 수용에 미치는 사용자 집단별 차이 분석

김정철(Jung-Cheol Kim),이춘열(Choon Yeul Lee),이인석(Lee In Seog),강희주(Hee Joo Kang) 한국데이타베이스학회 2013 Journal of information technology applications & m Vol.20 No.1

It has been found that users" characteristics are important variables that explain information systems adoption. These user groups, which are called COIs (Community Of Interests), might show different behaviors to each other to the same information system. We study differences in MDM (master data management) system adoption between military users and SI developers using TAM (Technology Acceptance Model). In case of military users, the perceived usefulness of an MDM system does not have impacts on intention to use an MDM system. Only the ease of use of an MDM system has impacts on intention to use an MDM system. However, in case of SI developers, both the perceived usefulness and the ease of use of an MDM system have impacts on intention to use an MDM system, which are similar to findings in previous studies. These results might be interpreted that users do not pay much attention to the usefulness in adopting a new information system in a centralized organization. They are obligated to use an information system whether it is useful or not. Thus the ease of use has more impacts on users than the usefulness.
