This study was conducted to investigate reasons for culling of Chungcheong dairy herds and to investigate the relationships between cow parity, interval from calving to culling, or season and culling reasons. Lactation data from 826 cows on 9 dairy farms from 2013 to 2015, including reasons for culling, dates of birth, last calving, and culling, were analyzed. The overall culling rate was 29.8% (246/826), with mammary problems (23.2%) being the most prevalent reason for culling, followed by infertility (14.2%) and downer cow syndrome (11.0%). The culling rate varied among farms (18.8-43.1%, p < 0.05), but was greater in parity $4{\leq}(40.7%)$ than parities 1, 2, or 3 (17.9-23.6%), whereas the rate was less frequent during mid lactation (21.1%) than in early (36.2%) or late (42.7%) lactation. Moreover, the culling rate was greater during summer (35.8%) than other seasons (20.3-23.2%). Mammary problems, downer cow syndrome, and metabolic disorders were the more common reasons for culling during early lactation, whereas infertility was predominant during late lactation. Our data show that the culling rate in Chungcheong dairy herds was associated with cow parity, interval from calving to culling, and season, with the main reasons for the removal of cows from dairy herds being mammary problems, infertility, and downer cow syndrome.

This study analyzed the reasons for continuing education among dietitians. An internet-based survey of 622 dieticians was conducted from August 31, 2012 to September 12, 2012. Based on data from the Participation Reasons Scale (PRS) questionnaire, factor analysis was conducted by principle component analysis for the extraction of major factors. Subsequent reliability analysis was performed by assessing Cronbach's ${\alpha}$. The ANOVA-test was performed to compare the participation reason scores for each factors according to general characteristics. Statistical analysis was performed using SPSS ver.17.0, and P<0.05 was considered significant. Factor analysis for the participation reasons revealed four types of factors. These factors were "maintenance and development of professional competencies", "interaction and responsibility of professionals", "job stability and personal profits" and "services for customers" respectively. Among the participation reasons, "maintenance and development of professional competencies" was the first reason with a 29.34% variance. In addition, the participation reasons for continuing education differed according to age (P<0.05), the highest level of education (P<0.05), workplace (P<0.01), and work experience in dietetic area (P<0.001). In conclusion, continuing education programs for dietitians should focus on effectively developing and promoting professionalism.

This study examined public perceptions of the reasons underlying sentence reduction for defendants convicted of sex crimes against persons with intellectual disability. An online survey was conducted among 522 adults in South Korea. Respondent endorsement of 20 reasons underlying sentence reduction, which were embedded within the respective rulings, and the perceived appropriateness of statutory sentence for the crimes committed were assessed. The results showed that most respondents endorsed the sentence; moreover, those who disagreed underscored the need for more severe punishment. Almost all the respondents perceived the following reasons and explanations unfavorably: impulsiveness caused by sexual arousal or alcohol consumption; an accidental occurrence; and personal characteristics such as defendant age, health condition, socioeconomic status, developmental history, and family background. However, there was a relative agreement in that the damage caused by the incident was relatively minor, or the defendant's reflection and attitude to recover the damage were used as reasons for the reduction. Differences in respondent perceptions of the reasons underlying sentence reduction as a function of gender and educational background were relatively small. However, younger respondents held harsher attitudes toward sentence reduction. The present findings underscore the need to be mindful of victims' statements and the characteristics of persons with intellectual disability while sentencing.

Before the 14th century, China had been thought as one of the countries with the most developed mathematics all along. But after the 16th century, Chinese mathematics increasingly walked up to the eclipse. The main reasons include the following points. First, the development of neoteric mathematics was closely associated with the social industrialization, but the lags in feudal China seriously blocked the development of the capitalistic seed, and China was still in the agricultural society then and couldn't step into the industrial society, which impeded the development of mathematics concerned with the industry and commerce. Second. the increasingly carrion feudalization was one of the essential reasons to block the development of Chinese neoteric mathematics. Finally, seeing about the developing logics of Chinese neoteric mathematics, we can find it was a scattered and experiential mathematical knowledge without strict and rational self-organizing structure system, which had the limitations existing in its interior mechanism.

Bulgogi (Korean-traditional barbequed beef) is one of the most globally well-known Korean foods. Though various attempts have been made to promote bulgogi, studies are limited understanding mostly to US consumers or foreigners who reside in Korea. China, the world's most populous country, has the biggest market potential in the world. The purpose of this study was to understand reasons of liking or disliking bulgogi products in Chinese consumers who reside in China in comparison to Korean consumers. The bulgogi used in this study differed in its main marinating ingredients. Check-all-thatapply (CATA) questionnaire was used to collect the reasons why one liked or disliked the given bulgogi product. CATA result showed that even for the same product, Korean and Chinese consumers liked or disliked it for different reasons. In particular, unlike Koreans, Chinese consumers reported sweet taste and garlic flavor as reasons for disliking the samples with high amounts of sugar and garlic, respectively. This seemed to be the result of differences in familiarity of consumers to certain tastes and flavors. The results imply the influence of culture in consumer preferences.
