In this paper, we dealt with substantial asset analysis methodology applied to two-dimensional asset classification and qualitative evaluation method according to the business process. Most of the existent risk analysis methodology and tools presented classification by asset type and physical evaluation by a quantitative method. We focused our research on qualitative evaluation with 2-dimensional asset classification. It converts from quantitative asset value with purchase cost, recovery and exchange cost, etc. to qualitative evaluation considering specific factors related to the business process. In the first phase, we classified the IT assets into tangible and intangible assets, including human and information data asset, and evaluated their value. Then, we converted the quantitative asset value to the qualitative asset value using a conversion standard table. In the second phase, we reclassified the assets using 2-dimensional classification factors reflecting the business process, and applied weight to the first evaluation results. This method is to consider the organization characteristics, IT asset structure scheme and business process. Therefore, we can evaluate the concrete and substantial asset value corresponding to the organization business process, even if they are the same asset type.

This study is to estimate differences, relationships and related factors of environmental risk perception and perceived benefit among residents and workers. A self-administered questionnaire survey using a structured instrument was carried out to residents and workers in industrial area during April, 2002. Total number of participants were 657 including 329 residents and 328 workers. Participants assessed environmental risk perception, self- assessed knowledge, trust in authorities and perceived benefit associated with 10 products manufactured in industrial area. There were difference in environmental risk perception, knowledge and trust in authorities and perceived benefit among residents and workers. Especially, trust in authorities and perceived benefit were statistically significant difference among residents and workers. Inverse relationships between environmental risk perception and perceived benefit have been observed for different products. In other words, the greater the perceived benefit, the lower the perceived risk, and vice versa. Factors mostly associated with participant's characteristics of environmental risk perception were age. marriage status (workers), education level (workers). There was statistically significant difference. Perceived benefit was statistically significant difference with sex, marriage status, residence duration, education level (workers). Related factors of environmental risk perception among residents and workers were age, trust in authorities. And factors affecting the perceived benefit were sex, age, education level (workers), and trust in authorities (workers). According to the results, people having high trust in the authorities perceived less risks than people having low in the authorities. To improve the communication of risk information, further study focus on assessment of experts, government and stakeholder in industrial area. Methodologies of this study can be used as the basis for investigating the structure of public perception of environmental products risks and benefit, designing a public information and risk communication program, and developing policy actions to improve acceptance.

The purpose of this study was to investigate the levels of risk perception characteristics for food risk elements using a psychometric paradigm from 298 university students in Yeungnam region, Korea, by a self-administered questionnaire. The respondents showed the highest level of risk concern about radioactive contaminated foods and the lowest level about GM (genetically modified) foods. In the risk perception characteristics for food risk elements, they perceived radioactive contaminated foods as a catastrophic, worried, new, and uncontrollable risk. In addition, they regarded food additives and foodborne illness as a chronic, controllable, old, and scientifically and individually known risk. According to the results of the factor analysis for risk perception characteristics, dread and unknown were categorized. In the risk perception map, mad cow disease, heavy metal contaminated foods, and radioactive contaminated foods were considered as a dreaded and unknown risk, whereas pesticide residues and GM foods were perceived as a less dreaded and unknown risk. Additionally, food additives and foodborne illness were regarded as a less dreaded and known risk and endocrine disruptors and avian influenza as a dreaded and known risk. These results imply that risk perception characteristics of consumers should be considered to establish strategies for risk communication in food science.

This study reviewed the national standards for risk management to judge whether they are suitable for a product safety management program. Among the standards issued from Australia, New Zealand, Canada, Japan, and UK, the risk management guideline (AS/NZS 4360: 2000) issued jointly from both Australia and New Zealand have better features for product safety management program than any other risk management standards in view point of broad definition of risk concept including opportunities of loss and gain, stepwise composition of management processes applicable iteratively, and integrable form of structure addible to existing management practice. Comparing the three product safety management programs suggested by several authors yielded common features of product safety management program model: (1) organization for product safety, (2) risk identification, (3) risk evaluation, (4) risk treatment, (5) monitoring/communication, and (6) documentation. All of these activities can be performed within risk management framework proposed by AS/NZS 4360.

The purpose of this study was to assess the prospective teachers' perception of food risk with the goal of providing the ways to improve their knowledge and perception of food risk. A self-administered questionnaire was developed and offered to 307 freshman and sophomore in an elementary teacher-cultivating university located in Seoul. The collected data were analyzed in terms of frequencies, cross tabulation analysis, t-test and ANONA with a deviation level of 5% using SPSS 15.0. The results of this research were as follows: 'Taste' was identified as an important factor for purchasing food (54.4%), and 'Manufacture date/expiration date' (67.0%) was checked first before food was purchased. The respondants viewed food additives (66.8%) followed by environmental contaminants (17.6%) as the most dangerous factors for food consumption. Even though they did not know the actual level of risk these factors posed to food, they still perceived them as dangerous. Most of them did not have any educational experiences on food risk, and if any, their sources of information were TV (46.6%) and the internet (19.5%). And, they did want to have information on food risk through TV, radio (41.1%) and the internet(16.4%). Based on the above results, the subjects who have great potential to influence children appeared not to have sound knowledge or a balanced perception of food risks. Therefore, systematic educational opportunities for prospective teachers should be provided to promote food risk communication.

The objective of this study is to investigate the effect of pesticide-related accident on prices and sales of eggs and the perception of food safety accidents among consumers. For this, we analyzed the impact of the pesticide incident on consumers' purchases by separating large discount stores and eco-friendly specialty stores with econometrics methods. In addition, the value changes for each egg certification were analyzed after the accident. Perception of food safety accidents was conducted through a survey to investigate the awareness of the pesticide-related accidents, changes in purchases, and the causes of the pesticide accidents. Furthermore, the risk analysis was conducted. This results show the importance of trust and communication in food safety accidents between distributors, consumers and concerned authorities. Also, after the accident, consumers' interest and premium exist in the breeding process such as animal welfare, not only in the final product. Therefore in order to actively respond to food safety accidents such as pesticides-related accident, response and improvement are necessary considering various aspects such as risk assessment, risk management, and risk communication.

Purpose: The purpose of the research is to explore the role of social media in attracting international patients for cosmetic services in South Korea during the COVID-19 pandemic. The study aims to conceptualize social media as an effective marketing tool for minimizing perceived risks associated with cosmetic services and increasing patient satisfaction. Methods: The study validated proposed hypotheses using the PROCESS macro for SPSS with overseas patients who received cosmetic treatment in private Korean plastic surgery clinics in Busan. Results: This study found that information delivery capability reduced perceived risk and contributed to patient satisfaction, while communication capability did not show any significant relationship with perceived risk and satisfaction. In addition, information delivery capability had a significant direct effect on patient satisfaction, but communication capability did not. Conclusion: It is expected that the outcomes of this study will broaden our understanding of the use of social media in reducing perceived risk and increasing satisfaction.
