The decision to integrate mobile cloud computing (MCC) in higher education without first defining suitable usage scenarios is a global issue as the usage of such services becomes extensive. Consequently, this study investigates the security determinants of the educational use of mobile cloud computing among universities' students. This study proposes and develops a theoretical model by adopting and modifying the Protection Motivation Theory (PMT). The study's findings show that a significant amount of variance in MCC adoption was explained by the proposed model. MCC adoption intention was shown to be highly influenced by threat appraisal and coping appraisal factors. Perceived severity alone explains 37.8% of students "Intention" to adopt MCC applications, which indicates the student's perception of the degree of harm that would happen can hinder them from using MCC. It encompasses concerns about data security, privacy breaches, and academic integrity issues. Response cost, perceived vulnerability and response efficacy also have significant influence on students "intention" by 18.8%, 17.7%, and 6.7%, respectively.

The purpose of the present study is to empirically examine factors that affect the information security awareness and perceived information security risk of employees of port companies. In particular, in order to identify factors that affect the perceived information security risks, we investigated the relation of assets, threats, and vulnerabilities to it, using the risk analysis methodology. With A total of 252 valid questionnaires, we also performed the structural equation modeling analysis using AMOS. It was found that first, there was no meaningful relationship between the information assets and the perceived information security risk in the case of employees of port companies. Second, threats and vulnerabilities turned out to have positive influences on the perceived information security risk. Finally, there was a positive relationship not only between the information security awareness and the information security education, but also between the information security awareness and the intention of information security. However, there was no meaningful relationship between the information security concern and the information security awareness.

Cybercrimes are the biggest threat that can influence the future of e-commerce, particularly in difficult times such as the COVID-19 pandemic. This pandemic has resulted in noticeable changes in e-customer behaviour represented in three types: spending rates, types of goods bought, and the number of purchasing times. Moreover, the percentage of cybercrime in many countries, including Saudi Arabia, has increased during the pandemic. The increase in the number of cybercrimes during the COVID-19 crisis and the changes in consumer behaviour shows that there is an urgent need to conduct research on the factors that have led to this. This study will explore the most significant factors that have an effect on the unexpected change of customer behaviour and cybercrime perceived risk during the COVID-19 pandemic in Saudi Arabia. The finding of the study will hopefully contribute to attempts in finding safer methods for shopping online during COVID-19 and similar crisis.

This study was undertaken to explain weight control behavior and intention of obese children and adolescents as measured by the elements of the health belief model. A total of 732 obese students from 28 schools in Seoul metropolitan area and their mothers were assessed with a self-administered questionnaire. The analyzed results are as follows; 1. Among obese students, 45.3% of male students and 57.2% of female students, a significantly higher portion than male students, reported that they had tried to lose weight within the recent year. Exercise was the most frequently used method to lose weight followed by diet control, drug use, and specialized clinic visits, in descending order. 2. Male students were more likely to try to lose weight if they perceived a low threat level and their mother had a job, and female students were more likely to try to lose weight if they were younger in age, perceived a low threat level and had strong external motivating factors. 3. Female students showed a significantly higher level of intention to obesity control than male students, and the intention level of their mothers also showed the same trend. 4. In male students, the degree of weight dissatisfaction, weight control experience, the level of obesity related beliefs of students, the educational level of the mother and economic status of the family were significant predictors of intention to obesity control, and in females, age, the level of obesity related beliefs of students and intention of their mothers were significant. In the mothers of male students, obesity index of students, age of the mother and the level of obesity related beliefs of the mother were significant predictors of intention of the mother, and in the mothers of female students, obesity index of students, occupational status of the mother and obesity related beliefs of the mother were significant. 5. According to the path model of intention to obesity control, the degree of weight dissatisfaction had the most powerful effect in male students, and perceived net benefit level was the most important variable in female students. Since the weight control behavior and intention of obese students were more predictable by the degree of weight dissatisfaction than the obesity index, we can conclude that only the students dissatisfied with their weight are well motivated for obesity control. There can be a discrepancy between the mother and her child's beliefs and intention status(especially in male students), so the therapists should also assess the student's opinion as well as the mother's. In female students, the perceived net benefit level wag the most important predictor of intention to obesity control, therefore the intervention program should pay particular attention to the positive benefits of weight control rather than negative aspects(threats) of obesity.

Purpose: This study was to investigate the prevalence & types of workplace violence toward nurses in hospitals, and to understand nurse's coping response, cause of violence and prevention strategy. Methods: The data were collected from 254 nurses working in 9 hospitals in Jeju Province by the self-report from June to August 2010. Results: The respondents experienced unpleasant or insulting words (89.8%), verbal threat (38.2%), physical threat (67.7%), physical injury (32.7%), severe physical injury (2.8%), and sexual harassment (26.4%) during the last one year. The frequent offenders were patients, patients' family and physicians in order. The causes of violence which nurses perceived were personality of offenders (76.4%), lack of assessment of aggressive patients or care givers (42.1%), and lack of explanation to patients or caregivers (33.5%). They reported that coping strategies for workplace violence were 'established reporting system (63.4%)', 'building a cooperative circumstances within team members (58.3%)', and 'formulation of hospital policies for violence prevention and coping (54.3%)'. Conclusion: These findings showed nurses are at considerable risk for workplace violence, and they experience various types of violence from patients, caregivers, and physicians. We suggest that hospitals formulate appropriate policies, guidelines and programs to prevent and cope with workplace violence in hospitals.

This study investigates the effect of mimicry buying on differentiation behavior in the context of fashion product consumption. Merging insights from social identity theory, optimal distinctiveness theory and previous research on narcissism, this article presents ingroup-outgroup categorization, narcissistic tendency and social status to serve as boundary conditions of this effect. Experiment 1 supports the hypothesis that more differentiation behavior against mimicry buying is reinforced when the mimicker is an in-group member compared to an out-group member. Based on this result, we conducted Experiment 2 to understand the effect of narcissistic tendency and mimicker's social status on differentiation behavior in the in-group context. The results show that the effect of narcissistic tendency on differentiation behavior is mediated by a perceived distinctiveness threat when the mimicker is an in-group member. In addition, this mediating effect is moderated by the mimicker's social status. Narcissistic tendencies have a direct negative effect on differentiation behavior when the mimicker is an in-group member with a high social status. However, high narcissistic tendency induces a more distinctiveness threat when the mimicker is an in-group member with a low social status. This then results in a greater differentiation behavior. Implications for marketers and suggestions for future research are also discussed.

With the increasing use of social media, the occurrence of cyber crimes on social media has also increased. In this paper, we focus on online sexual harassment among various cyber crimes and discuss how social media users use social media to avoid online sexual harassment. Drawing on threat avoidance theory, the factors affecting avoidance motivation were identified. Avoidance motivation was measured based on the affordance of social media, and the influence of the degree of sexualization was tested to examine how environmental factors affect motivation behavior. The results indicated that the more users perceived sexualization on social media, the lower their motivation to avoid sexual harassment. Thus, it is important to create an atmosphere on social media where crime is minimized, and users are able to respond appropriately by continuously managing their accounts on these platforms.

Background: This study aimed to examine whether cases of punishing false claimants threat general physicians to check their medical cost claims with care to avoid being suspected, and identify empirically general deterrence effects of the on-site investigation system in the Korean National Health Insurance. Methods: 800 clinics were selected among a total of 15,443 clinics that had no experience of on-site investigation until June 2007 using a stratified proportional systematic sampling method. We conducted logistic multiple regression to examine the association between factors related to provider's perception of on-site investigation and high level of perceived deterrence referring to fear of punishment after adjusting provider's service experiences and general characteristics. Results: The probability of high perceived deterrence was higher 1.7 times (CI: 1.13-2.56), 2.73 times (CI: 1.68-4.45) each among clinics exchanging the information once or more per year or once or more for 2-3 months than among clinics no exchanging the information about on-site investigation. Also, the probability of high perceived deterrence was higher 2.27 times (CI: 1.28-4.45) among clinics that knows more than 3 health care institutions having experienced an on-site investigation than among clinics knowing no case. Conclusion: A clinic knowing more punishment cases by onsite investigation and exchanging more frequently information about on-site investigation is likely to present high perceived deterrence. This result will provide important information to enlarge preventive effects of on-site investigation on fraud and abuse claims.

Cancer is still a threat to human beings. The incidence and mortality rate of cancer have been gradually increasing as the life span has been lengthened. Radiotherapy is one of the most commonly used treatments for cancer. This study explored the influence of social support and stress on sick role behavior of patients receiving radiotherapy for cancer. The subjects for this study were 60 patients undergoing radiotherapy for cancer, selected from the radiotherapy treatment unit of the out patient departments of two major medical centers in Jeonju. Data were collected from February 1 to 28, 1990 by a Likert Scale Questionnaire and an interview schedule designed by the inverstigator. Data analysis included percentages, mean and standard deviation, t or F-test, Pearson Correlation Coefficient and stepwise multiple regression. Results included the following : 1. Support came primarily from sons and daughters (90.1%) ; the type of support was primarily emotional support from friends(60.0%) ; informational support came from health personnel(81.7%) ; and material support was sons and daughters(40.0%) ; satisfaction with support was highest for the spouse(4.02$\pm$.52). 2. Among the patient's demographic status was occupation the was the only socioeconomic characteristic influencing sick role behavior (F＝2.91 , p＝.029). 3. Directly perveived support was positively correlated with sick role behavior (r＝.2374, p＝.034). 4. Stepwise multiple regression was used to determine the predictors of sick role behavior. Directly perceived support was the most significant predictor accounting for the hightest contribution to sick role behavior(5.6%). Directly perceived support. socioeconomic status, perceived stress and indirectly perceived support variables together, accounted for only 6.8% of sick role behavior.
