This paper examines the relationship between economic dependence and gender differences in housework in Korea. There are three explanatory alternatives for the relationship; economic rule of exchange, gender display perspective and deviant neutralization. We analysed both 2004 and 2009 time use survey data. The findings show the significant gender differences in time spent on housework that wives spend much more time on housework than husbands. However, among couples with non-normative gender roles, in some cases the more economically powerful wives spend more time on housework than breadwinner wives with weaker economic power, although such cases are rare. Rather, it is appropriate to conclude that, the more economically independent the wives, the less time they spend on housework; this is also the case for husbands. Overall, the Korean case shows what the economic exchange theory predicts. Thus, improvements in working wives' economic power will lead to gender equity in the division of housework.

정보시스템 아웃소싱(outsourcing)의 적용 범위와 그 규모가 증대함에 따라, 아웃 소싱은 정보시스템의 관리에서 근본적인 이슈로 등장하게 되었다. 정보시스템 아웃소싱의 중요성이 인식되었으나, 그에 대한 실증적 연구는 매우 미흡한 설정이다. 본 연구의 주요 목적은 정보시스템 아웃소싱에 있어 고객회사(client firm)와 서비스 제공업자(vendor)간의 관계의 성공 및 실패에 영향을 미치는 요인을 조사하는 것이다. 본 연구의 연구 모델은 관 계적거래이론(relational exchange theory), 커뮤니케이션 행동(communication behavior), 거래비용분석(transaction cost analysis) 등의 조직간관계(interorganizational relationship) 이론에 기반을 두고 작성되었다. 미국의 207개 회사의 정보시스템 아웃소싱 설문조사에 의 하여 다음과 같은 연구결과가 도출되었다. (1) 서비스 제공업자의 능력(vendor capability), 관계결속성(solidarity), 관계지속성(continuity expectation), 유연성(flexibility), 서비스업자의 활동에 대한 모니터링(monitoring of the vendor), 참여도(participation) 등이 아웃소싱 관 계의 성공과 양의 상관관계를 가지고 있으며, (2) 역할연합도(role integrity), 자산특이성 (asset specificity) 등은 아웃소싱 관계의 성공과 음의 관계를 가지고 있는 것으로 나타났 다. 이 결과에 의하면, 비관계적 거래(discrete exchange) 보다는, 관계적 거래(relational exchange)에 기반을 두어 아웃소싱 관계를 운영하는 것이 아웃소싱의 성공적인 구현을 필 수적으로 보여진다. 이 연구 결과를 기초로 하여 아웃소싱 대상 업무의 선택, 서비스 제공 업자의 선택, 그리고 아웃소싱 관계의 지속적인 관리를 위한 지침을 제시하였다.

Purpose Issues related to information security have been a crucial topic of interest to researchers and practitioners in the IT/IS field. This study develops a research model based on a Structure-Conduct-Outcome (SCO) framework for the social exchange relationship between employees and organizations regarding information security. Design/methodology/approach In applying an SCO framework to information security, structure and conduct are activities imposed on employees within an organizational context; outcomes are activities that protect information security from an employee. Data were collected from 438 employees working in manufacturing and service firms currently implementing an information security policy in South Korea. Structural equation modeling (SEM) with AMOS 22.0 is used to test the validation of the measurement model and the proposed casual relationships in the research model. Findings The results demonstrate support for the relationships between predicting variables in organization structure (security policy and physical security system) and the outcome variables in organization conduct (top management support, security education program, and security visibility). Results confirm that the three variables in organization conduct had a positive effect on individual outcome (security knowledge and compliance intention).

This paper studies, from a quantity theory of money perspective, the reasons that North Korean inflation and exchange rates maintain stability while its economy is experiencing difficulties due to the international community's economic sanctions. In doing so, this paper uses both domestic and foreign currencies in an analytic model based on the quantity theory of money to cautiously reflect North Korea's dollarization as well as its management of its exchange rate. In particular, foreign currency holdings are divided into those for store-of-value purposes and those for transaction purposes. This paper shows that in the early stages, in which the amount of foreign currency holdings for store-of-value purposes is decreasing while the amount of foreign currency holdings for transaction purposes is intact, inflation and exchange rates both exhibit stable movements. In the middle stages, where the amount of foreign currency holdings for transaction purposes begins to fall, exchange rates show some increase and inflation decreases. In the final stages, when the amount of foreign currency holdings for transaction purposes significantly decreases, exchange rates and inflation both increase, and in some situations a crisis can happen. According to this paper's analysis, if the economic sanctions continue to the extent that the amount of North Korean foreign currency holdings for transaction purposes starts to fall, the exchange rate and inflation stability we see now are unlikely to be maintained.

Cryptographic protocol design in a two-party setting has of tel ignored the possibility of simultaneous message transmission by each of the two parties (i.e., using a duplex channel). In particular, most protocols for two-party key exchange have been designed assuming that parties alternate sending their messages (i.e., assuming a bidirectional half-duplex channel). However, by taking advantage of the communication characteristics of the network it may be possible to design protocols with improved latency. This is the focus of the present work. We present three provably-secure protocols for two-party authenticated key exchange (AKE) which require only a single round. Our first, most efficient protocol provides key independence but not forward secrecy. Our second scheme additionally provides forward secrecy but requires some additional computation. Security of these two protocols is analyzed in the random oracle model. Our final protocol provides the same strong security guarantees as our second protocol, but is proven secure in the standard model. This scheme is only slightly less efficient (from a computational perspective) than the previous ones. Our work provides the first provably- secure one-round protocols for two-party AKE which achieve forward secrecy.

Based on the core value of the Q&A community, the contribution of knowledge and information has a great impact on users' community evaluation. As a small social group, the relationships and interactions among community members are quickly formed through information technology. As such, the cognitive evaluation of the relationship between community members will have an impact on the intention of information contribution. This research builds on the previous research based on the social exchange theory and establishes a dual model of swift guanxi in examining the relationship between guanxi and continuous knowledge contribution. In the current study, 305 survey questionnaires were used and 249 valid questionnaires were used for analysis. The analysis results are as follows: First, information support has a positive impact on dedication-based swift guanxi. While hypothesis between information support and constraint-based swift guanxi was not be supported. Second, emotional support has a positive impact on the formation of swift guanxi from a dual perspective. Third, the swift guanxi from the dual perspective has a positive impact on the intention of continuous knowledge contribution. Finally, although personal involvement has an adjustment effect, it is a downward adjustment effect, hypotheses are not supported. The current study offers theoretical and practical implications in field of knowledge management, specifically knowledge contribution in the virtual community.

This research introduced the concept of 'alternative attractiveness' derived from the social exchange theory to the research model predicting turnover intention among salesforce. By doing so, we tried to broaden the understandings of relationship between salesperson job attitude and salesperson behavior. We collected and analysed the data from the survey on the 178 salespeople employed at the life insurance companies. We found the alternative attractiveness to be a significant antecedent of the turnover intention. Specifically, the more attractive the alternative the greater the intention of turnover. However, we also found that the salesforces are less attracted to the alternative if they are more satisfied with their jobs. Finally, this research can be a seminary work with the relational perspective for the studies of salesforce management.

The goal of this study is to broaden our understanding about the antecedents for job turnover intention of salesforces. In addition to the previously studied antecedents such as job performance, satisfaction, organizational commitment, in this study we are particularly interested in the variable of alternative attractiveness which is often studied in social exchange theory, Thus, we suggest a model with a new antecedent for job turnover intention by introducing alternative attractiveness. We collected and analyzed the data from the survey on the 178 salespeople at the life insurance companies. We find the alternative attractiveness as an significant antecedent for the turnover intention. Specifically, the more attractive the alternative the greater the intention of turnover. However, we also find that the salesforces are less attracted to the alternative if they are satisfied with their works, Therefore, we believed this research can be a seminary work with the relational perspective for the studies of salesforce management.

Examination of the various impact factors on adoption sustainable IT can influence on the potential for creating sustainable businesses in today's society. However, the societal factor out of environmental factors, which stimulates customer intention to use sustainable IT, has seldom been investigated. In this paper, we examine the adoption of sustainable web technology from the pro-social behavior perspective. The concept of sustainable IT is theoretically examined based on social exchange theory. An empirical investigation is conducted into customer intention to use new sustainable IT. The results indicate that customers care about the social responsibility and usefulness of the sustainable IT-based services they choose. In this study, the social features of web technology and their influences on adoption are verified empirically for the first time. In addition, pro-sociality is identified as necessary to a perception of the socially responsible features of information technology. Furthermore, pro-social adoption behavior in the beginning stages of sustainable IT use is elucidated.
