Providing trading partners with personal information to establish an e-commerce financial transaction is inevitable. Most e-commerce companies keep personal information and transaction data for user's convenience and develop additional services as their applications. However, keeping personal information increases the likelihood of identity theft causing direct or indirect damage while it may simplify repetitive financial transactions. This study introduces risk management methods based on quantitative and qualitative analysis including demand-supply curve model and Gordon & Loeb model to analyze the risks for security management. The empirical analysis with survey results from KISA (Korea Information Security Agency) shows that the root cause of different statistics of personal information leakage incidents according to core business of internet companies is the difference in their Loss Expectancy caused by them. Also we suggest disciplinary compensation and higher standard for personal information protection as a solution to prevent the variation of investment on it between individual companies.

The purpose of this study is to explore the relationship between national reputation, culture and communication based on the intercultural communication theory. The 18 foreign residents in Korea were interviewed. The analysis of in-depth interview reveals that culture and communication are very important factors in establishing the national reputation. The qualitative research showcases that the cultural acculturation types(separation, integration, and assimilation) are grouped as foreigners adapt and acculturate to the residence. Especially, the assimilation is very essential type in having the in-group expectancy and the loyalty to Korea. The results reveal that a higher level of heterogeneity of a personal network('Korean in-group network') is associated with a higher level of reputation and loyalty to Korea. This suggests that having outgroup members in individuals' personal networks facilitates outgroup communication competence and loyalty to Korea.

The advancement in ubiquitous healthcare specifically in preventive healthcare can lead to longer life expectancy especially for the elderly patients. To aid in preventing premature loss of lives as well as lengthening life span, this research aims to implement the use of mobile and wireless sensor technology to improve the quality of life and lengthen life expectancy. The threats to privacy and security have received increasing attention as ubiquitous healthcare applications over the Internet become more prevalent, mobile and universal. Therefore, we propose Context-aware Service of U-Healthcare Application based Knowledge using Ontology in secure health information exchange. This research also applies ontology in secure information exchange to support knowledge base, context modeling, and context reasoning by applying the general application areas for ontologies to the domain of context in ubiquitous computing environments. This paper also demonstrates how knowledge base, context technologies, and mobile web services can help enhance the quality of services in preventive ubiquitous healthcare to elderly patients.

Objectives : The evaluation of disability after trauma in psychiatry is relatively subjective compared with other departments. A consensus among evaluators could improve reliability of evaluations. We compared disability rate of common psychiatric disorders without definite brain injury depending on their diagnosis from experienced evaluators in Korea. Methods : A written questionnaire was mailed to each evaluator and the reply was analyzed. The questions included disability rate ranges of postconcussional syndrome, PTSD and depression. Other questions related with admission for evaluation, expected duration of treatment, life expectancy and need of supporting person were also asked. Results : Range of disability rate were from $8.6{\pm}4.5%$ to $26.6{\pm}12.8%$ in postconcussional syndrome, from $10.4{\pm}6.8%$ to $36.4{\pm}13.8%$ in PTSD and from $10.0{\pm}4.6%$ to $30.6{\pm}10.3%$ in depressive disorder. There were lots of diversity in expected duration of treatment with psychiatric disability. Decline of life expectancy and need of supporting person were considered at least 50% of disability. Conclusion : There is much diversity in evaluation of psychiatric disabilities with disability rate and expected duration of treatments even among experienced evaluators. A common consensus among experts may increase reliability of psychiatric evaluations after trauma.

Background: Thyroid tumors are generally regarded as rare malignancies. Nowadays, however, their global incidence is growing continuously partially due to western life style and utilization of more sensitive methods of early detection. It is approximately three times more prevalent in females than in males. Most cases of thyroid cancer are asymptomatic nodules or just have local cervical symptoms or adenopathy in early stages. Materials and Methods: The Global Burden of Diseases report 2010 study (released 3/2013) profited from 100 collaborators worldwide and used a vast network of data on health outcomes, vital registries, and population surveys. It shared many of the Global Burden of Diseases 1990 principal databases such as all available data on injuries, diseases, risk factors, as well as comparable metrics, and used different scientific approved methods to estimate important health status data like: death rate, life expectancy, healthy adjusted life expectancy, disability-adjusted life years (DALY), years of living lost due to premature death and years of life with disabilities. Results: DALY as thyroid cancer burden per 100,000 Iranian populations had increased by about 14% during 1990 to 2010 in all ages; from 6.1 (95% UI 4.2-9.74) years in 1990 to 6.95 (95% UI 5.06-9.18) years in 2010 in both sex. The 2010 peak age-group was estimated at 45-49 years in males and 40-45 years in females.

Recently, mobile and smart devices are rapidly spreading. As a result, real estate services, which were formerly face-to-face, have now been replaced by mobile environments. This study focuses on the real estate app service and 261 samples were used for the empirical analysis. The results of the hypotheses test using structural equation model are summarized as follows. First, performance expectancy, facilitating conditions, security and aesthetic perceived by users of real estate services have positively influence on positive attitude, but effort expectancy and social influence do not. Second, positive attitude of real estate services have positive effects on service Acceptance. Third, involvement moderated the relationship between positive attitude and service Acceptance. Based on the results of the analysis, it provided meaningful implications for practitioners and researchers in related fields.

This paper reviews studies on information searching behavior in process control systems and discusses some implications learned from previous studies for use in human factors studies on nuclear power plants (NPPs) main control rooms (MCRs). Information searching behavior in NPPs depends on expectancy, value, salience, and effort. The first quantitative scanning model developed by Senders for instrument panel monitoring considered bandwidth (change rate) of instruments as a determining factor in scanning behavior. Senders' model was subsequently elaborated by other researchers to account for value in addition to bandwidth. There is also another type of model based on the operator's situation awareness (SA) which has been developed for NPP application. In these SA-based models, situation-event relations or rules on system dynamics are considered the most significant factor forming expectancy. From the review of previous studies it is recommended that, for NPP application, (1) a set of symptomatic information sources including both changed and unchanged symptoms should be considered along with bandwidth as determining factors governing information searching (or visual sampling) behavior; (2) both data-driven monitoring and knowledge-driven monitoring should be considered and balanced in a systematic way; (3) sound models describing mechanisms of cognitive activities during information searching tasks should be developed so as to bridge studies on information searching behavior and design improvement in HMI; (4) the attention-situation awareness (A-SA) modeling approach should be recognized as a promising approach to be examined further; and (5) information displays should be expected to have totally different characteristics in advanced control rooms. Hence much attention should be devoted to information searching behavior including human-machine interface (HMI) design and human cognitive processes.
