The purpose of this study is to clarify the real causes of gender wage differentials in Korea by analyzing changes over the period from 1984 to 1999. The participation rate of women in the Korean labor force has gradually increased since 1963, reaching 47.4 percent as of 1999. This increase can be attributed to more active participation by women of all ages, except those aged 15-19, as a result of their enrollment in higher level education. In particular, a remarkable rise in labor market participation was achieved by those aged 25-29. On the other hand, the ratio of female workers earnings to that of male workers has increased from 45.1 percent in 1972 to 63.1 percent in 1999. However, when the gender wage differentials are decomposed into various factors, it is found that discrimination components against female workers, compared to the skills or productivity characteristics, played a greater role for the 1994 to 1999 period.

Cyberloafing is as counterproductive behavior because it is the act of using internet for personal purposes which can affect employees' productivity, especially when done excessively (more than 4 hours a week). The objective of this study was to analyze whether gender and education level had significant effect on cyberloafing among generations in the workplace. From 267 respondents, gender was not found to have impact on cyberloafing because female and male respondents had the same frequency of low level cyberloafing. However, female had higher excessive cyberloafing than male. Gen Y had significant impact on the relationship between education and cyberloafing but Gen Y with diploma degree was revealed to have excessive cyberloafing. Furthermore, Gen X had started combining professional and personal lives throughout their daily lives. Hence, organizations should foster a culture of hard work by giving challenging job with clear target and worthy incentive but still implementing internet usage policy.

Running title: Adequacy of dentist supply Objectives: The proper provision of dentists is very important for delivering the dental care that people need. The purpose of this study is to evaluate the adequacy of dentist supply and to predict the proper supply of dentists in Korea for the next 10 years. Methods and materials: Using the data from 2004 to 2017 in the Statictics Korea, the dental needs were measured as days of admission and the annual total dental care hours in 2020, 2023, 2026 and 2030 were predticted using regression analysis. The dental care productivity (average in-office hours) of dentists was analyzed using regression analysis including age, gender, education level and region as a confounder. The annual care hours were predicted according to seven scenarios based on the percentage of women among dentists, post-dentist education levels, the percentage of dentists in the metropolitan area, aging and retirement age. Results: The needed dentist based on the data in the Statictics Korea will be 27, 288 ~ 27, 311 in 2020, 28,104 ~ 28,1785 in 2023, 28,977 ~ 29,124 in 2026, and 30,174 ~ 30,413 in 2030. On the other hand, the number of dentists in Korea will be 26,945 in 2020, 28,813 in 2023, 30,682 in 2026 and 33,173 in 2030. The adequacy index of dentist supply will be -0.01 in 2020 to +0.10 in 2030. Conclusions: Our data showed that dentists will be adequately supplied in Korea for the next 10 years. Overall, the ratio between dentist versus 1,000 Koreans will be increased from 0.5 in 2019 to 0.7 in 2020, which will meet the mean of OECD countries.

Bovine fecal microbiota is important for host health and its composition can be affected by various factors, such as diet, age, species, breed, regions, and environments. The objective of this study was to evaluate the impact of diet and gender on fecal microbiota in Korean native Hanwoo cattle. The 16S rRNA gene amplicon sequencing of fecal microbiota was conducted from 44 Hanwoo cattle divided into four groups: (1) 11 heifers fed an oat hay plus total mixed ration (TMR) diet for breeding (HOTB), (2) 11 heifers fed an early fattening TMR diet (HEFT), (3) 11 steers fed the early fattening TMR diet (SEFT), and (4) 11 steers fed the late fattening TMR diet (SLFT). Firmicutes and Bacteroidota were the first and second most dominant phyla in all the samples, respectively. The Firmicutes/Bacteroidota (F/B) ratio associated with feed efficiency was significantly greater in the SLFT group than in the other groups. At the genus level, Romboutsia, Paeniclostridium, and Turicibacter were the most abundant in the SLFT while Akkermansia, Bacteroides, and Monoglobus were the most abundant in the HOTB group. Although the same early fattening TMR diet was fed to Hanwoo heifers and steers, Marvinbryantia and Coprococcus were the most abundant in the HEFT group while Alistipes and Ruminococcus were the most abundant in the SEFT group. Shannon and Simpson diversity indices were significantly lower in the SLFT group than in the other groups. Distribution of fecal microbiota and functional genetic profiles were significantly different among the four treatment groups. The present study demonstrates that different diets and genders can affect fecal microbiota and the F/B ratio may be associated with feed efficiency in Hanwoo cattle. Our results may help develop strategies to improve gut health and productivity through manipulation of fecal microbiota using the appropriate diet considering Hanwoo cattle gender.

Background: Online teaching and learning extend the duration of using gadgets such as mobile phones and tablets. A prolonged usage of these gadgets in a static position can lead to musculoskeletal disorders (MSD). Therefore, this study aims to identify the risk factors related to musculoskeletal symptoms while using gadgets during work from home due to the COVID-19 pandemic. Method: A cross-sectional survey with online-based questionnaires was collected from the University of Indonesia, consisting of lecturers, students, and managerial staff. The minimum number of respondents was 1,080 and was defined by stratified random sampling. Furthermore, the dependent variable was musculoskeletal symptoms, while the independent were age, gender, job position, duration, activity when using gadgets, and how to hold them. Result: Most of the respondents had mobile phones but only 16% had tablets. Furthermore, about 56.7% have used a mobile phone for more than 10 years, while about 89.7% have used a tablet for less than 10 years. A multivariate analysis found factors that were significantly associated with MSD symptoms while using a mobile phone, such as age, gender, web browsing activity, work, or college activities. These activities include doing assignments and holding the phone with two hands with two thumbs actively operating. The factors that were significantly associated with MSD symptoms when using tablets were gender, academic position, social media activity, and placing the tablet on a table with two actively working index fingers. Conclusion: Therefore, from the results of this study it is necessary to have WFH and e-learning policies to reduce MSD symptoms and enhance productivity at work.

This study was conducted to observe the effects of crossbreeding and gender on the carcass traits and meat quality of Korean Native Black Pig (KNP) and $KNP{\times}Duroc$ crossbred ($KNP{\times}D$). A total of 50 pigs comprising seven KNP barrows, eight KNP gilts, twenty $KNP{\times}D$ barrows and fifteen $KNP{\times}D$ gilts were used in this study. Animals were reared in the same housing condition with same feed diet for six months prior to slaughter. After an overnight chilling, the carcasses were graded, and samples of Musculus longissimus dorsi were obtained for meat quality analysis. The slaughter and carcass weights and dressing percentage of $KNP{\times}D$ were higher (p<0.001) than those of KNP. The slaughter and carcass weights and backfat thickness of barrows were higher (p<0.01) than those of gilts. There were no significant difference in carcass conformation and quality grade between KNP and $KNP{\times}D$ as well as barrow and gilt. Fat content of $KNP{\times}D$ was higher (p<0.001) than that of KNP. Fat content of barrow was higher (p<0.001) than that of gilt. There was interaction between crossbreeding and gender on the fat content. KNP gilt showed higher fat content than KNP barrow whereas $KNP{\times}D$ barrow showed higher fat content than $KNP{\times}D$ gilt. Lightness, redness, yellowness, chroma and hue angle values and color preference of meat of $KNP{\times}D$ were lower (p<0.001) than those of KNP. Redness, yellowness and chroma values of meat of barrow were lower (p<0.05) than those of gilt. It is concluded that crossbreeding KNP with Duroc increases carcass productivity and meat fat but decreases meat color values and preference. Crossbreeding of KNP with Duroc produces a better fat deposition in meat of barrows than in gilts.

Background: The health of the economically active population contributes to increased corporate productivity by reducing the productivity loss caused by disease and increasing job efficiency, which in turn is a national benefit. Since the economically active population is a concept encompassing workers and a source of economic development for a country, that population's health should be treated with importance not only from a personal standpoint but also at a national level. Methods: In this study, data of 11,007 adults aged 20 years and older who participate in economic activities were analyzed in the five-year Korea Health Panel Study from 2010 to 2014 including the number of dental visits and dental medical expenses. Results: Factors related to "gender," "education level," "age," "duty category," "income level," "employment type," "national health insurance," and "chronic disease status" of the economically active population are affected in relation to the number of visits and dental medical expenses. The number of dental visits increased with higher education levels (p<0.001), and the number of visits to the dentist increased with older age (p <0.001). Dental medical expenses were 91,806 Korean won (KRW) more for "white-collar workers" than for "blue-collar workers" (p<0.03), and 127,674 KRW more for "regular workers" than for "atypical workers" (p<0.02). Conclusion: When it is necessary to improve policies to enhance the efficiency of the distribution of health and medical resources in the overall balance of the dental health sector, we should try to identify various factors of oral health disorder due to income inequality among the classes according to the country's employment type in order to find ways to reduce the health gap among the social classes.
