Purpose: This study attempted to examine the risk of stock price plunge according to the firm's management strategy. Prospector firms value innovation and have high uncertainties due to rapid growth. There is a possibility of lowering the quality of financial reporting in order to meet market expectations while withstanding the uncertainty of the results. In addition, managers of prospector firms enter into compensation contracts based on stock prices, thus creating an incentive to withhold negative information disclosure to the market. Prospector firms' information opacity and delays in disclosure of negative information are likely to cause a sharp decline in share prices in the future. Research design, data and methodology: This study performed logistic analysis of KOSPI listed firms from 2014 to 2017. The independent variable is the strategic index, and is calculated by considering the six characteristics (R&D investment, efficiency, growth potential, marketing, organizational stability, capital intensity) of the firm. The higher the total score, the more it is a firm that takes a prospector strategy, and the lower the total score, the more it is a firm that pursues a defender strategy. In the case of the dependent variable, a value of 1 was assigned when there was a week that experienced a sharp decline in stock prices, and 0 when it was not. Results: It was found that the more firms adopting the prospector strategy, the higher the risk of a sharp decline in the stock price. This is interpreted as the reason that firms pursuing a prospector strategy do not disclose negative information by being conscious of market investors while carrying out venture projects. In other words, compensation contracts based on uncertainty in the outcome of prospector firms and stock prices increase the opacity of information and are likely to cause a sharp decline in share prices. Conclusions: This study's analysis of the impact of management strategy on the stock price plunge suggests that investors need to consider the strategy that firms take in allocating resources. Firms need to be cautious in examining the impact of a particular strategy on the capital markets and implementing that strategy.

The scope and functions of a conversational agent are gradually expanding. In particular, research and technology development is being conducted on a conversational agent that can speak first without user calls. However, still in its early stages, there is a lack of research on how a preceded utterance conversational agent will affect users. Accordingly, this study conducted a 2×3 mixed design using the user's task performance condition and the agent's self-exposure as independent variables and measured Intimacy, Functional Satisfaction, Psychological Reactance, and Workload as dependent variables to identify the effects of preceded utterance conversational agent on user experience.

The use of social media has many advantages such as knowledge sharing, social networking, and communicating with other people. However, it has given rise to various side effects including stress, Which is defined as social network stress in this study. This study aims to conceptualize social network stress and investigate its effect on switching behavior in social media. For this purpose, we present a research model that consists of the antecedents and consequences of social network stress and test it empirically using LISREL 8.7 based on the structural equation model. The empirical results showed that knowledge sharing and self-disclosure had positive impact on social network stress, which in turn positively influenced social media switching behaviors. In conclusion, we discussed both theoretical and practical implications of this research and suggested its limitations.

The purpose of this study was to examine the effect of donation expenditure details and the shift in awareness as a result of disclosure of donation expenditure details in order to promote constant donation by nonprofit organizations in the course of marketing activities. The first experiment was configured through $2{\times}2$ intergroup element design based on 2(feedback on donation expenditure details: available vs. unavailable) ${\times}$ 2(donation awareness: expenditure vs. exchange), and furthermore, MANOVA was performed. The results showed that the satisfaction with donation was higher when the donation expenditure details were disclosed(M=5.125, SD=0.437) and that the relation maintenance intention was higher(p<0.01) when the donation expenditure details were disclosed M=5.328, SD=0.459). In addition, the main effect was validated by using the bootstrapping method. The results of overall model validation showed that satisfaction & trust(=0.843, p<0.01) and satisfaction(=0.267, p<0.01) and trust(=0.691, p<0.01) had a positive(+) relationship. Based on aforesaid results, donors are expected to have greater trust if nonprofit organizations make effort to ensure transparent and detailed disclosure of information on expenditure of donations made by donors. Succeeding studies would need to investigate the effect that might vary depending on the type of feedback methods, etc.

This study aims to find the causal relationship between the effects of apartment inhabitants' life management and administrative management on housing satisfaction. The study results are as follows. Firstly, life management showed to have a positive effect on life satisfaction. In other words, the better the management of public order and facilities, the higher the satisfaction of housing satisfaction. Thus, the principal agent of management needs to increase inhabitants' housing satisfaction through education and training on developing life management techniques. Secondly, administrative management showed to have a positive effect on life satisfaction. Thus, the more accurate the completion documents and management transfer process necessary for administrative management, the higher the cost-cutting effects of accounting, construction, and service contracts, the more transparent the resident agreement process in accordance with management policies, the more transparent the election process of building representatives and resident representatives, and the higher the effects of energy saving, the higher the housing satisfaction of inhabitants. This revealed that the principal agent of management needs to increase housing satisfaction through education and training on developing administrative management techniques because the level of administrative management had a positive effect on housing satisfaction. As a result, in order to create reliability between inhabitants and the principal agents of management, the transparency of administrative management such as document disclosure must be ensured, thus improving the housing satisfaction of inhabitants.

Purpose: This study is to investigate the effect of managerial ownership level in distribution and service companies on the stock price crash. The managerial ownership level affects the firm's information disclosure policy. If managers conceal or withholds business-related unfavorable factors over a long period, the firm's stock price is likely to plummet. In a similar vein, management's equity affects information opacity, and information asymmetry affects stock price collapse. Research design, data, and methodology: A regression analysis is conducted using the data on companies listed on the Korea Composite Stock Price Index (KOSPI) between 2012-2017 to examine the effect of the managerial ownership level on stock price crash risks. Results: Logistic and regression results indicate that the stock price crash risk was reduced as managerial ownership levels are increased. The managerial ownership level has a significant negative coefficient on stock price crash risk, negative conditional return skewness of firm-specific weekly return distribution, and asymmetric volatility between positive and negative price-to-earnings ratios. Conclusions: As the ownership and management align, the likeliness of withholding business-related information is reduced. This study's results imply that the stock price crash risk reduces as the managerial ownership level increases because shareholder and manager interests coincide, thereby reducing information asymmetry.

The diffusion of advanced mobile technology has introduced new types of personal information or 'location data'. These new data mean new opportunities for businesses, such as location-based services (LBS), but have resulted in new consumer anxieties regarding disclosure of personal information. This study examines the effects of the consumers' perceived control over "time-andplace" information in location-aware services on their perceived privacy risk. A total of 270 respondents participated in this study. Conditions of perceived privacy control were operationalized over time-and-place information, in a $2{\times}2$ factorial design. Results indicate that the perceived control over time-and-place personal information is a significant predictor of perceived risk, and control assurances over time-and-place information enhances the perception of control, thus alleviating the perceived risk. In addition, the effect is much more significant when time and place were combined.

In the rapidly changing business environment, companies are introducing information technology to effectively manage internal resources in order to achieve a sustainable competitive advantage. We presented the Enterprise Social Network Service(SNS) as new information technology. Enterprise SNS provided employers with sociable functions like Facebook while supporting general task such as mail, authorization and notice. In this research, we focused on Enterprise SNS and suggested self-disclosure, enjoyment in helping others, perceived organizational support, generativity capacity as antecedent variables of Enterprise SNS usage. In addition, we verified the effect of the mediating role of generativity capacity between Enterprise SNS usage and job performance. For empirically verifying the proposed model, we collected sample data from 225 workers using Enterprise SNS and conducted analysis using a structural equation modeling. We expect that this study provides managers who are interested in introducing enterprise SNS with insights on how to facilitate enterprise SNS usage. Also, this study suggests useful theoretical implications to researchers who are interested in the use of enterprise SNS from the context of knowledge management.

This study firstly focused on development of an after-school program for school-aged children, and secondarily exploring the relationship between the after-school program and social competency of school-aged children. The program was composed of 10 two-hour sessions. The main goal of the program was to instill a sense of self-acknowledge, self-worth, responsibility and belonging to society and social activities. The subjects of this study were 29 children of first, second and third glades at the elementary schools in Seoul. This program was administered from March to May 1999. The data were analysed by frequency, mean, and paired t-test using the SAS program package. The major findings of this study were summarized as follows; There were significant differences in the degrees of social competency between before and after participating in the program(t=1,92 p<.05). The after-school program for school-aged children affect social competency variable as ‘initiative’(t=3,52 p<.001), but do not affect ‘sociability’, ‘responsibility’or ‘self-disclosure’. These results lead us to conclude that an after-school program of this type would be useful for developing peer-interation and for later social competency.

본 연구는 인간의 자아표현 욕구와 창조적 욕구로 인해 자신을 대체할 산물들을 끊임없이 만들어 내는 과정에서 중요하게 작용되는 자기노출라는 심리를 이용하여 아바타와 학습자의 얼굴을 합성하는 증강가상을 통하여 가상세계에서의 현실감을 부여함으로써 학습자의 몰입을 유도하여 그 교육적 효과를 증대하고자 하였다. 이를 실증하기 위하여 컴퓨터기반으로 컨텐츠를 개발한 후, 로봇 컨텐츠로써의 활용을 위해 컨버팅하고 자동 로딩을 통한 학습자의 사진을 아바타와 합성시켰다. 실험 결과 자기노출기반 컨텐츠의 효과는 모든 집단의 경우에서 학습에 대한 집중도에는 긍정적인 영향을 주었으며, 학업성취도에는 유의미하지는 않지만 긍정적 효과를 가지는 것으로 나타났다. 이는 교육용 로봇을 활용한 자기노출 개념 적용에 대하여 긍정적인 결과라고 보여지는데, 보다 유의미한 결과를 얻기 위해서는 단순히 사진을 찍어 로딩시키는 증강가상보다는 얼굴검출을 통한 실시간 증강가상과 같이 증강가상 효과의 증대가 필요하다고 하겠다.
