Purpose: The purpose of this study was to examine the awareness of alcohol use during pregnancy and factors influencing the intention to abstain from alcohol during pregnancy by drinking levels. Methods: Utilizing a comparative descriptive design, a total of 359 female college students were recruited. Measurements were Theory of Planned Behavior (TPB) variables related awareness of alcohol use during pregnancy, Korean Version of the Alcohol Use Disorders Identification Test, knowledge about alcohol use during pregnancy, and socio-demographic factors. Main variables were compared by drinking levels. The factors influencing the intention to abstain from alcohol during pregnancy were identified using hierarchical regression analysis. Results: Non-problematic alcohol behavior group (n=185) had higher the intention to abstain from alcohol during pregnancy than problematic alcohol behavior group (n=174) (t=3.13, p=.002). The significant TPB variables influencing the intention to abstain from alcohol during pregnancy were that attitudes (β =-.44, p<.001), subjective norms (β =.14, p=.026), and perceived behavior control (β =.19, p=.002) in non-problematic alcohol behavior group, whereas the corresponding variables in the problematic alcohol behavior group were attitudes (β =-.51, p<.001) and subjective norms (β =.21, p=.006). Conclusion: It is necessary to increase the intention to abstain from alcohol during pregnancy for the female college students having problematic alcohol behavior. The following strategies are recommended for them; decreasing acceptable attitudes toward alcohol use during pregnancy and reinforcing the influence of social pressure toward to abstain from alcohol during pregnancy.

IEEE 802.11ax is a protocol being developed for high-density Wireless Local Area Networks (WLAN). Several algorithms have been proposed to improve the level of spatial reuse applied in IEEE 802.11ax. However, these algorithms are tentative and do not specify how to select the transmit power and carrier sense threshold in practice; It is unclear when and why the tuned parameters lead to better network performance. In this paper, we restricted the scale of transmit power tuning to prevent the case of backfire in which spatial reuse will result in transmission failure. If the restrictions cannot be satisfied, spatial reuse will be abandoned. This is why we named the proposed scheme as Arbitration based Spatial Reuse (ASR). We quantified the network performance after spatial reuse, and formulate a corresponding maximum problem whose solution is the optimal carrier sense threshold and transmit power. We verified our theoretical analysis by simulation and compared it with previous studies, and the results show that ASR improves the throughput up to 8.6% compared with 802.11ax. ASR can avoid failure of spatial reuse, while the spatial reuse failure rate of existing schemes can up to 36%. To use the ASR scheme in practice, we investigate the relation between the optimal carrier sense threshold and transmit power. Based on the relations got from ASR, the proposed Relation based Spatial Reuse (RSR) scheme can get a satisfactory performance by using only the interference perceived and the previously found relations.

Entrepreneurship research has focused on several factors that might affect the intention of an individual to start an enterprise. Using principles from social network theory and the entrepreneurial intention model (EI), the current research intends to investigate how social capital is formed on Social Networking Sites (SNS) and how the resulting social capital influences entrepreneurial intention. Using an online survey, 151 valid responses were received from university students. Applying partial least square structural equation modeling, positive and significant relationship was found between the SNS usage and bonding and bridging social capital. Further, it was also found that online-bonding social capital does not impact any of the three antecedents of entrepreneurial intention. On the other hand, online-bridging social capital significantly influences personal attitudes and subjective norms. It was also found that both personal attitude and perceived behavioral control significantly relate to EI, while the subjective norms do not relate significantly to EI. The paper contributes to the literature on technology-based human behavior and entrepreneurship in emerging countries, opening some areas for future research, while also providing some managerial insights. It also should be beneficial to educational institutions in understanding how the use of SNS use by students may be optimized.

This study intended to investigate the relationship between father's/mother's values(materialism, competitive achievement pressure, neighborhood relations), father/mother-student emotional intimacy & father's/mother's over control and university student's alienation, and examin the relative influences of independent variables on university student's alienation. For this purpose, data were obtained from 402 male 7nd female university students in Seoul and Inchon, and analyzed by factor analysis, Cronbach's $\alpha$, frequencies, %, Pearson's r and stepwise multiple regression. The major findings were as follows : 1) father's and mother's values had significant relations to university student's alienation. As father and mother had more materialism and competitive achievement pressure, their university student was more alienated, and as father and mother had more neighborhood relations, the student was less alienated. 2) Emotional intimacy between father/mother and student had negative relation to university student's alienation. As the level of emotional intimacy was higher, the student was less alienated 3) Father's and mother's over control had positive relations to university student's alienation. As father's and mother's over control was higher, the student was more alienated. 4) Mother's neighborhood relations, father's and mother's over control, mother-student emotional intimacy and father's materialism had influences on university student's alienation in descending order. These independent variables explained 25. 0 % of the total valiance. Father's materialism and father's/mother's over control increased the level of university student's alienation, but mother's neighborhood relations and mother-student emotional intimacy decreased the bevel of student's alienation. Emerging evidences suggested that in order to prevent or decrease the university student's alienation, their parents should have less materialism and more neighborhood relations, and should not use over control on their university student but produce more emotional support.

This study explores determinants of purchase intentions for vegan fashion products based on the modified planned behavior model. Survey data from 434 university students were subjected to an analysis using descriptive statistics, factor analysis, and structural equation modeling. The results showed that almost half of the consumers surveyed recognized vegan fashion products and a little more than a half of consumers surveyed had purchase experience for vegan fashion products. Clothing, bags, and shoes are the most frequently purchased vegan fashion product categories. From the results of the model test, purchase intentions on vegan fashion products were determined by attitude, subjective norms, ethical responsibility, and ethical identity of the consumers. When consumers have a more positive attitude, have higher subjective norms, stronger ethical responsibility, and stronger ethical identity regarding the purchase of vegan fashion products, they are likely to have a greater intention to purchase vegan fashion products. The findings contribute to the literature by adding test results for vegan fashion products among the ethical product categories, highlighting the importance of the consideration of product category, which can give somewhat different results when exploring ethical consumption. Based on these findings, marketers need to use special tags or signage highlighting the ethical values and meanings of vegan fashion products to better communicate with target consumers with a high level of ethical responsibility and to help increase consumers' control over purchase behaviors through reducing barriers generated by insufficient product information.

Purpose: This study was done to explore the predictors asssociated with Korean women smokers' intentions to quit smoking. Methods: This study was a cross-sectional study including 3,578 women smokers. Data from the 2010 Community Health Survey conducted by the Korea Centers for Disease Control and Prevention were examined and analyzed using SPSS 21.0 for multiple logistic regression. Results: Of the women smokers 52.2% reported having an intention to quit smoking but only 3.9% had received education in smoking cessation. In the logistic analysis, factors associated with intention to quit smoking were age (Odds ratio and 95% [confidence interval]: 0.97 [0.96-0.98]), health-related quality of life (OR=2.39 [1.14-5.03]), perceived stress (OR=1.11 [1.00-1.22]), marital status (OR=0.93 [.86-1.00]), age of starting to smoke (OR=1.14 [1.04-1.24]), number of cigarettes per day (OR=0.84 [0.76-0.93]), exposure to smoking-quitting campaigns (OR=1.48 [1.22-1.80]), previous attempts at weight-control (OR=1.37 [1.15-1.63]), frequency of alcohol use (OR=1.16 [1.01-1.34]), hypercholesterolemia (OR=1.62 [1.18-2.24]), experiences of trying to quit smoking (OR=4.04 [3.45-4.73]), and regular medical check-up (OR=1.13 [1.03-1.43]). Conclusion: Identifying factors associated with the intentions to quit smoking provides possibilities for shaping effective policies and programs to increase smoking cessation among Korean women.

Background: Cervical cancer is known as one of the most prevalent types of cancers and a major public health problem in developing countries which can be detected by Pap test, prevented, and treated. Despite the effective role of Pap test in decreasing the incidence and mortality due to cervical cancer, it is still one the most common causes of cancer-related deaths among women, especially in developing countries. Thus, this study aimed to examine the effect of educational interventions implemented by health volunteers based on protection motivation theory (PMT) on promoting Pap test use among women. Materials and Methods: This quasi-experimental study was conducted on 60 health volunteers and 420 women. The study participants were divided into an intervention and a control group. Data were collected using a valid self-reported questionnaire including demographic variables and PMT constructs which was completed by both groups before and 2 months after the intervention. Then, the data were entered into the SPSS statistical software, version 19 and were analyzed using Chi-square test, independent T-test, and descriptive statistical methods. P<0.05 was considered as statistically significant. Results: The findings of this study showed that the mean scores of PMT constructs (i.e. perceived vulnerability, perceived severity, fear, response-costs, self-efficacy, and intention) increased in the intervention group after the intervention (P<0.001). However, no significant difference was found between the two groups regarding response efficacy after the intervention (P=0.06). The rate of Pap test use also increased by about 62.9% among the study women. Conclusions: This study showed a significant positive relationship between PMT-based training and Pap test use. The results also revealed the successful contribution of health volunteers to training cervical cancer screening. Thus, training interventions based on PMT are suggested to be designed and implemented and health volunteers are recommended to be employed for educational purposes and promoting the community's, especially women's, health.
