정보화사업은 사회 다른 어느 분야보다 눈부신 발전을 보이고 있으며, 중앙부처는 전국공동활용체계 구축, 그리고 행정업무의 능률 제고를 위한 각종 사업들을 역점 추진하고 있다. 그러나 정보화 사업은 중앙부처 위주로 추진되어 개별기관별, 단위사업별로 정보화가 이루어지고 있다. 또한, 기초자치단체의 경우 종합적인 정보시스템추진계획 구도와 전략의 부재로 인해 다양한 정보화 사업들이 부서별로 산발적으로 추진되고 있으며, 이는 사업추진의 분할손은 물론 사업간 연계를 통한 상승작용을 저해하는 주 요인으로 작용할 가능성이 노출되고 있다. 중앙부처의 표준시스템의 개발 및 보급은 그 수용대상인 기초자치단체의 행정정보화를 앞당길 수 있는 긍정적인 영향과 더불어 기초자치단체의 수용능력여부에 따라 기초자치단체의 행정정보화는 그 혼란을 더욱 가중하는 부정적인 영향을 줄 수도 있음을 시사하고 있다. 본 연구는 이러한 표준시스템의 긍정적인 영향만을 인식하고 있는 구조를 파악함은 물론 간과하고 있는 부정적인 영향을 시스템사고를 이용하여 이해함으로써 표준시스템의 보급으로 인한 기초자치단체로의 역기능을 최소화하고, 그에 역동적으로 대처할 수 있는 방안으로 조직 측면에서는 CIO제도의 활성화와 정보담당조직위상의 제고를, 시스템 측면에서는 표준시스템과 기존시스템간의 GAP 분석을 통한 틈새도출 및 보강을, 데이터 측면에서는 공유정보제공시스템 구축을 통한 데이터 자원의 활용을 그 대안으로 제안하고 있다

This study explores diffusion of information on Covid-19 relating to China on You Tube. For this, information on Covid-19 relating to China was divided into factual information and disinformation, with factual information being categorized into positive and negative information. According to network analysis, there are lots of negative information and disinformation. On the contrary positive information is rare. There are lots of videos about rumor on the leak of Wuhan institute among disinformation. Rumor on the manipulation of genes has the highest average value of view count and betweenness centrality. Main stream youtube channel has only role of messenger which delivers messages as it is instead of fact-checking on disinformation. The fact which there are much more negative information or disinformation among videos about Covid-19 relating with China shows that Youtube users skewed toward negative information and disinformation than positive ones. In summary, disinformation on youtube brings spreadable effect by making user watch similar contents.

This study purported to test the independent impacts of positive and negative attributes of disconfirmation on satisfaction and loyalty of university students. The study utilized the nation-wide survey data previously collected from 1,400 students distributed across 32 universities in Korea. Using SPSS 22.0, the study adopted a 'Simple Regression Analysis' in order to calculate the causal coefficients among positive and negative attributes of confirmation, satisfaction, and loyalty. The study results showed that while positive disconfirmation had a positive impact(${\beta}=.188$) on satisfaction, but not on loyalty, negative disconfirmation had negative impacts on satisfaction(${\beta}=-.326$) and loyalty(${\beta}=-.105$). Based on the study results this study suggests that universities should implement differential strategies to increase students' satisfaction and loyalty. The results also showed that negative disconfirmation had 2~7 times greater impacts on satisfaction and loyalty than the impacts positive confirmation had. Supporting the 'asymmetric relations' of positive and negative disconfirmation, the study suggests that universities should pay special attention to students' complaints.

The purpose of the study is to investigate the effects of information search for Korean food brand on perceived risk and preference. To achieve this goal, using 10 exemplary restaurants appointed as Korean food brands in Seoul, a questionnaire survey was used to collect data through interview. Using the SPSS 21.0. total 296 responses were analyzed to test the relationship among variables. The findings are as follows. First, information search for Korean food brand showed that all external search, internal search and direct experience had a positive effect on preference. Second, there was no difference between information search for Korean food brand, risk perception and preference according to gender, but there was a significant difference between information search for Korean food brand, risk perception, and preference according to their age. Third, indifference moderated the relationship between external and internal information search and Korean food preference. Fourth, maladjustment moderated the relationship between external information and direct experience for Korean food preference.

This study investigates whether and how a firm's cost of equity is influenced by the extent of a firms's name change. Even though corporate name change doesn't give any benefit to investors, it can be a signaling about firm's future valuation. And also, if that signaling has high credibility, it can be decrease information cost and the firm's cost of equity. on the contrary to this, if corporate name change is kind of break with the past and corporate image laundering, it is bad signaling to investors. So it can be increase information risk and the firm's cost of equity. Using yearly cross-sectional regressions of the cost of equity on our proxies for corporate name change, size, beta, market-to-book ratio and other innate risk factor over the 2005-2010, we find that the cost of capital is positively associated with corporate name change after controlling for all other factors. This result implies that corporate name change increase information risk of the business, and thus increase information asymmetries between managers and outside investors with respect to a firm's true future value. This increases information risk, and creates an adverse selection problem, on the part of outside investors. Rational investors therefore demand a premium for bearing this corporate name change-related information risk, which in turn leads us to observe a positive relation between the intensity of corporate name change and the cost of equity.

The present study examined the factors influencing individuals' risk information seeking and processing using the case of 2015 MERS outbreak in Korea. Analyses of two-wave online panel data demonstrated that perceived risk, negative affect, subjective norm, and information insufficiency predicted the risk information seeking/avoiding as well as information processing mode, which validates the Risk Information Seeking and Processing(RISP) model. More importantly, this study found new evidence that information seeking and systematic processing promoted MERS preventive behaviors. In addition, active SNS use moderated the link between perceived risk and negative affects about MERS crisis as well as the relationship between social normative pressure and to seek the risk related information.

In order to determine the level of awareness of nuclear power generation and Fukushima contaminated water, this study conducted an online survey targeting the general public living in the Busan area and analyzed a total of 201 questionnaires. Independent samples t-test and one-way analysis of variance were conducted to verify differences in variables according to the characteristics of the study subjects, and correlation analysis was conducted to confirm the correlation between variables. First, the results of the study showed that women had a more negative perception of nuclear power generation and Fukushima contaminated water than men. In terms of age, it was found that people in their 40s and older had a high level of negative perception. In terms of political inclination, progressive respondents showed a higher negative perception toward nuclear power generation and Fukushima contaminated water. Second, information on nuclear energy was most often collected through the Internet, broadcasting, and SNS. Third, the higher the negative perception of nuclear power generation, the more negative the results were in terms of issues of concern following the discharge of contaminated water at the Fukushima nuclear power plant. Nuclear power cannot be separated from human life. Therefore, it is believed that accurate information and a knowledge delivery system are needed to ensure correct awareness of nuclear power generation.

새로운 시스템의 수용은 대부분의 경우 유용성이나 사용용이성과 같은 이성적인 평가와 함께 기존 시스템 사용에 대한 무의식적인 습관에 따라 결정된다. 흥미롭게도 기존 시스템에 대한 습관의 효과는 상이한 방향을 가질 수 있다. 어떤 경우에는 전환비용 때문에 부정적이 될 수도 있지만 어떤 경우에는 현 시스템에 대한 풍부한 경험 때문에 긍정적인 효과를 보일 수도 있다. 본 연구에서는 기존 시스템에 대한 습관과 새로운 시스템에 대한 판단 간의 관계가 새로운 시스템에 대한 직접 경험에 따라 달라질 수 있음을 가설로 제시하였다. 즉, 새로운 시스템에 대한 경험이 없으면 부정적인 관계가 되겠지만 경험이 있는 경우에는 긍정적인 관계가 될 수도 있다. 이 가설들에 대한 타당성을 보여 주기 위해 168명의 우리나라 대학생들을 대상으로 실증적 검증을 하였다. 수용 대상은 구글 닥스(Google Docs) 이었고 조사에 참여한 학생들은 이전에 구글 닥스에 대한 경험을 가지고 있지 않았다. 조사 참여자 전부에게 구글 닥스에 대한 특성을 설명한 뒤 임의로 두 그룹으로 나눈 다음 한 그룹은 구글 닥스를 실제 사용할 기회를 주었고 다른 그룹에게는 주지 않았다. 결과적으로 경험을 한 그룹은 기존 시스템에 대한 습관과 새로운 시스템에 대한 주관적 판단 간에 부정적인 관계를 보인 반면 경험이 없는 그룹은 긍정적인 관계를 보였다.

This study investigates the underlying mechanism of YOLO in millennial consumer, especially the influence of perceived economic recession on the present-biased preference. In addition, it was attempted to expand the implicit theory by proposing the individual's entity belief as a mediator for the effect of perceived economic situation on consumers' present-biased seeking behavior. In three experimental studies, undergraduate students who both highly primed and measured negative economic situation showed more favorable attitudes towards present-biased persuasive message and related products. The results of this research provides practical implication for marketers especially in the current situation experiencing economic slowdown due to low economic growth and COVID 19.
