Cigarette smoking is one of the major causes of preventable diseases, disability, and death in Korea and worldwide. It has been clearly linked to the most common causes of death among the elderly and contributes to morbidity and disability associated with many chronic illnesses that are common in this age group. The health benefits of smoking cessation for the elderly have been clearly demonstrated. However, few studies have analyzed the relationship between health and smoking by considering the following many factors, especially among disabled people. In this study, we discuss the impacts of many factors on smoking among disabled people. Adults with disabilities are more likely to smoke than their peers. Public health agencies and practitioners should consider what reasonable adjustments may need to be made to policies and interventions to ensure that they are effective for adults with disabilities.

This study was performed to develop the molecular marker for sex determination of hare (Lepus coreanus) distributed in Korea which focused on sexual dimorphism between X and Y chromosomal homologous genes, zinc finger-X (ZFX) and -Y (ZFY). The intron 7 regions of ZFX and ZFY genes exhibited differential amplification patterns between male and female hares. The lengths of intron 7 region of ZFX and ZFY genes were 538 and 233-bp, respectively. Especially, the ZFX intron 7 contained a repetitive sequence identified as member of RNA-mediated transposable elements which was similar to CSINE2 commonly found in the rabbit genome. However, it was not present in intron 7 of ZFY gene. The molecular sex typing by polymerase chain reaction (PCR) was also carried out to determine the sex of hare based on difference in lengths between the intron 7 regions of ZFX and ZFY genes. All DNA samples tested had common band amplified from ZFX. However, the male hare DNAs had two distinct bands which amplified from ZFX and ZFY genes, respectively. The results from ZFX-ZFY PCR sex typing were identical to those from phenotypic investigation and from amplification patterns using male-specific sex determining region Y (SRY) gene as well. Finally, this study suggested that the sexual dimorphism between intron 7 regions of ZFX and ZFY could be useful genetic marker to determine sex of hare.

This study is aimed to compare cross-cultural individualism, and consider an influence of nationality, gender and age on individualistic propensity. The survey data include 271 Chinese, 251 Japanese, 262 Netherlander and 267 Korean. The result of factor analysis, four factors named independent action, profit and opinion, indifference on other and will, were found out. The result of comparison on nationality, Netherlander and Japanese has a strong individualistic propensity, and Korean has a remarkable collective propensity. Chinese were middle grade among 4 countries. It can be said that certain factors correlated with a certain country, because Netherlander's answer on questions belonged to profit and opinion factor were highest, and Japanese's one belonged to indifference on other were highest. On gender, Man was more individualistic better than woman. On age, twenties has strong collective propensity better than other age groups. The number of significant difference on comparison among countries is 21 in 21 questions, but the number on gender or age is 6 or 7. Therefore, it can be said that nationality (or culture) is most useful variable to grasp individualism.

The purpose of this study is to examine the trends of income inequality by gender since 1997 economic crisis and to investigate what is the most influential factor on these changes for males and females. Data used for this study are nine waves of Korean Labor and Income Panel Study(KLIPS). Income inequality is measured by the Gini coefficient and the mean logarithmic deviation(MLD) and the MLDs are decomposed into three components to quantify within- and between-group inequalities. The results show that the extent of income inequality is greater for women during the whole period and is fluctuated more widely. Women's income inequality is mainly affected by the family-related variables, such as age and marital status, while men's inequality is primarily determined by the labor market factors, such as employment status, industrial types and occupation status. These results imply that gender-sensetive welfare policies need to be implemented and that it is necessary to assist the poor women and men through the benefits from the income assistance programs and labor market programs.

This study evaluated gender preferences regarding the mechanical properties of polymers that are typically used as cooperative robot skin. Gender-based preferences of workers aged 20~30 and polydimethylsiloxane were examined according to the body parts which is most frequently in contact with the robot during operation. The factors influencing preference, i.e., stiffness and stickiness, as measured by strain rate and contact angle, respectively, were analyzed to compare gender-based differences. Female preferred stiffer materials with small strain rates while male preferred softer materials with large strain rates. As a result of evaluating mechanical properties of the materials to relate to gender-based preference, we found that female tended to prefer Dragon-skin with the lowest stickiness, and a low strain rate, during compressive creep tests. In contrast, male tended to prefer Ecoflex with high strain rate regardless of stickiness. Therefore, these results provide basis for material selection when considering cooperative robot skin.

This study aims to evaluate the satisfaction of students with a block system and it's effect on preparing students for a culinary career in the future. Summing up the outcomes of this study, male students reported higher levels of satisfaction than female students not only regarding a block system $perse$ (significant level 0.05) but with regards to career preparation as well (level 0.01). According to the choice variations disclosed by this study, a strong correlation exists with each of the p-values 0.000. Additionally, satisfaction with a block system appears to be strongly related to how well it is perceived to prepare students for future jobs with a RSQ = 0.840. Summing up the study's conclusions on gender effects, satisfaction with a block system is higher for males than females due to its being physically harder to take for female than for male students. Also, student grades have no correlation with satisfaction with a block system while they show significant differences in future job will. Freshmen (first year students) displayed the strongest level of satisfaction regarding future career preparation while seniors (fourth year students) the lowest. According to these results, we can posit a theory; gender and study years have an effect on the satisfaction with a block educational program and perceived value of career preparation. Therefore, culinary instructors and planners should consider this study's results to improve student satisfaction and future job preparedness.

Objective : The purpose of this study was to systematically review sex differences in episodic memory. Methods : We searched previous studies published in all electronic databases between 2010 and 2019. The key terms used in the search were 'sex differences' or 'gender differences' and 'episodic memory' or 'autobiographical memory'. 8 studies were finally extracted for analysis. Results : The 8 studies had evidence levels of II (67.5%) and III (37.5%), which are quite high. Healthy younger adults or healthy adults were recruited to examine sex differences in episodic memory. Assessment methods for episodic memory were mainly divided into cognitive tasks or standardized tests using visual or auditory stimuli. Subjects were instructed to memorize the stimuli and asked to recall them after some time. Overall females outperformed male. In particular, there were significant sex differences in verbal episodic memory. In contrast, there was no significant sex difference in visual episodic memory. Conclusion : To identify sex differences in episodic memory, a variety of test methods were used in various ways. Overall, females showed higher episodic memory than males. These findings suggest a need for cognitive intervention considering sex differences in the clinic. In the future, episodic memory tests with high ecological validity should be conducted to investigate sex differences in episodic memory.

The purpose of this research is to investigates 10-year trajectories of cognitive functions among older adults in their 70s to understand changes in cognitive functions as a continuum until very late life. This study also examines differences in trajectories of cognitive functions by gender and by changes in marital status, especially widowhood. Among participants of the Korean Longitudinal Study of Ageing(KLoSA), the sample of this study includes 800 older adults in their 70s during the first study wave (2006) and those who reported their cognitive functions for six consecutive study waves (2006, 2008, 2010, 2012, 2014, and 2016). The analyses were conducted in two steps. First, we conducted Latent Class Growth Analyses(LCGA) to investigated heterogeneous trajectories of cognitive functions in 10 years. Then, we performed multinomial logistic regression. Three heterogeneous trajectories of cognitive functions were identified. One group of 48.7% of older adults showed high cognitive function at baseline and maintained it over 10 years. Second group of 14.7% of older adults reported low cognitive function scores at baseline and showed continuous decline over time. Third group of 36.6% were showed mid-level cognitive functions and maintained their functions over time. We also found significant gender differences but not significant differences in marital status when we consider both in our model; however, the we found significant differences in changes in marital status when we did not consider gender in the model. The results suggest that the importance of considering dynamics of gender and changes in marital status to understand changes in cognitive functions in later life.
