We surveyed the emotional images of three kinds of scientific technologies in people's mind and the perception of technologies in terms of their risks and benefits. The contents of the image and their image values were used to estimate the affects on each technology. As an affect heuristic hypothesis predicted, people perceived the technology more beneficial or riskier depending on their overall affect. In other words, those who have positive affect on the technology Perceived less risky and more beneficial than those who have negative affect. On the other hand, those who have negative affect on the technology perceived riskier and less beneficial than those who have positive affect. We also found negative relationship between the perceived risk and perceived benefit of each technology. The implications of our findings that suggest affective heuristic were discussed in terms of the measurements of affect and the necessity of communication of scientific technologies with the public.

In study I, Domain-Specific Risk Taking Scale(DOSPERT) was translated into Korean and was validated that it had 6 factors structure and showed adequate reliability and validity, using the data had been collected from 438 participants. In study 2, two research problems were examined using the data had been collected from 497 participants who were different from study I. First, the mediation effect of sensation seeking and perceived benefit on the relationship between narcissism and risk-taking were examined. Using path analysis, it found that sensation seeking and perceived benefit mediated the relationship between NPI narcissism and risk-taking fully, and between PNI narcissism and risk-taking partially. Seceond, the moderate effect of contingencies of self-worth(CSW) on the relationship between perceived benefit-risk and risk-taking was examined. Using multi-group analysis, it found that virtue CSW moderated the relationship between perceived benefit-risk and total risk-taking, various CSWs moderated the relationships between perceived benefit-risk and 6 sub domains of risk-taking. These results were compared with previous studies of risk-taking and discussed the relevance of the narcissistic type.

This study investigated the relations of adolescents' attitudes toward risk behaviors, perceived benefits and costs, and their risk behaviors. The subjects were 955 high school freshmen in the Daegu$\cdot$Kyungpook area. The major findings were as follows. (1) Adolescents' attitudes toward risk behaviors were positively associated with the perceived benefits of adolescent risk behaviors, but these were negatively associated with the perceived costs of adolescent risk behaviors. (2) Compared to boys, girls had more positive attitudes toward adolescent drinking. In addition, girls perceived more benefits but less costs of adolescent risk behaviors than did boys. (3) There were no gender differences in the relationships between dependent variables and adolescent risk behaviors.

Organizations that make widely use of information technologies can be more efficient. But, the dependence of information technologies leads to an increase in threat of security. This is the reason why organizations are investing in security risk management (SRM) which is designed to protect of information assets. Noting a lack of empirical research in SRM, we investigate the key factors having a direct effect on performance of SRM. Particularly, this study focused on identifying factors influencing awareness of SRM and Intention to develop SRM in Organization. Based on relevant literature review, six motivating factors, including Behavior for Security Management, Compliance with Security Policy, perceived Benefits, Perceived Sacrifice, Social Pressure, Experience of Security Risks, were initially identified. The results indicated that most perception factors were positively related to Organization's intention to develop SRM and awareness of SRM, which then had positive impact on performance of SRM. But Perceived Sacrifice was not significantly related to two variables which is Organization's intention to develop SRM and awareness of SRM.

High-resolution images are drawn from existing seismic data which were originally obtained by Korea Ocean Research & Development Institute (KORDI) during 1994-1997 for deep seismic studies on the East Sea of Korea. These images are analyzed for mapping Quaternary faults and near-bottom gas pockets. First 12 channels are selected from shot gathers for reprocessing. The processing sequence adopted for high-resolution seismic images comprises data copy, trace editing, true amplitude recovery, common-midpoint sorting, initial muting, prestack deconvolution, bandpass filtering, stacking, highpass filtering, poststack deconvolution, f-x migration, and automatic gain control (AGC). Among these processing steps, predictive deconvolution, highpass filtering, and short window AGC are the most significant in enhancement of resolution. More than 200 Quaternanry faults are interpreted on the migrated sections in the shallow depths beneath the seafloor. Although numerous faults are found mostly at the western continental slope and boundaries of the Ulleung Basin, significant amount of the faults are also indicated within the basin. Many of these faults are believed to be formed with reactivation of basement, from geotectonic activities including volcanism, and often originated in Tertiary, indicating that the tectonic regime of the East Sea might be unstable. Existence of shallow gas pockets casts real hazardous warnings to deep-sea drillings and/or to underwater constructions such as inter-island cables and gas pipelines. On the other hand, discovery of these gas pockets heightens the interests in developing natural resources in the East Sea. Reprocessed seismic sections, however, show no typical seismic characteristics for gas hydrates such as bottom-simulating reflectors in the western continental slope and ocean floor.
