The objective of this study was to determine the perceptions and knowledge of farmers of heat stress and tick resistance in cattle. A cross-sectional survey was conducted and 110 farmers in four villages in the sour and sweet velds of the Eastern Cape Province, South Africa were interviewed. The associations among area (municipality), gender, age, level of education, employment and religion were computed using Chi-square tests. The majority of the respondents had on average 4 bulls, 4 cows, 4 heifers, 4 calves, and 4 oxen. Milk was considered as the major (28.3%) reason for keeping cattle. Most farmers owned non-descript (72.6%), and Nguni (45.3%) cattle because of their heat tolerance (54.7%), tick resistance (54.7%), and milking ability (28.2%) traits. Excessive panting (56.6%) and disease transmission (76%) were regarded as the major effects of heat stress and tick infestation in cattle, respectively. About 50% of the respondents agreed that hair length influences tick resistance and 47.17% considered coat colour when acquiring cattle. In the sampled areas, ticks were prevalent in the summer season (93%), and 77.36% of the respondents use acaricides every fortnight. Gall sickness was reported to be a major problem in the cattle herds by 36.79% of the respondents. Our results showed that farmers in the two municipalities had knowledge of cattle adaptation to heat stress and tick resistance.

The objective of this study was to investigate the influence of increasing carcass weight (CW) on meat quality traits including meat color, water-holding capacity (WHC), tenderness, backfat thickness and intramuscular fat (IMF) content of pork loin. A total of 96 pork carcasses (48 LYD [Landrace × Yorkshire × Duroc] barrows and gilts) were selected at a commercial slaughterhouse. Each gender had commercial CW (≤ 90 kg), heavy CW (91-100 kg) and very heavy CW (> 100 kg) (16 carcasses from each CW group). Loin cuts (Longissimus lumborum) were excised to investigate meat color (CIE L*a*b*), drip loss, cooking loss, released water, Warner-Bratzler shear force (WBSF), and IMF content. Backfat thickness and IMF content of pork loin samples were significantly (p < 0.05) increased with increasing CW, although there was no significant difference in ultimate pH (pHu). CIE a* increased significantly (p < 0.05) with increasing CW, while there were no significant differences in CIE L* or CIE b* among CW groups. Although all WHC measures showed no significant differences among CW groups, WBSF increased significantly (p < 0.01) with increasing CW. Sensory flavor score was significantly increased while panel score for tenderness was decreased significantly (p < 0.001) with increasing CW. Consequently, CW had a positive correlation with flavor but negative correlation with tenderness. These results indicate that the increased IMF content improves flavor, juiciness and palatability, although tenderness deteriorates with increasing CW.

The vowel /o/ in Seoul Korean has been undergoing a sound change by altering the acoustic weighting of F2 and F1. Studies documented that this on-going change redefined the nature of a /o/-/u/ contrast as F2 differences rather than as F1 differences. The current study examined two cognitive factors namely executive function capacity (EF) and autistic traits, in terms of their roles in explaining who in speech community would adapt new acoustic forms of the target vowels, and who would retain the old forms. The participants, 55 college students speaking Seoul Korean, produced /o/ and /u/ vowels in isolated words; and completed three EF tasks (Digit N-Back, Stroop, and Trail-Making Task), and an Autism screening questionnaire. The relationships between speakers' cognitive task scores and their utilizations of F1 and F2 were analyzed using a series of correlation tests. Results yielded a meaningful relationship in participants' EF scores interacting with gender. Among the females, speakers with higher EF scores were better at retaining F1, which is a less informative cue for females since they utilized F2 more than they did F1 in realizing /o/ and /u/. In contrast, better EF control among male speakers was associated with more use of the new cue (F2) where males still utilized F1 as much as F2 in the production of /o/ and /u/ vowels. Taken together, individual differences in acoustic realization can be explained by individuals' cognitive abilities, and their progress in the sound change further predicts that cognitive ability influences the utilization of acoustic information which is non-primary to the speaker.

With the burden of chronic diseases mounting among the population as a result of its aging, the importance of health examination is being stressed in order to identify and manage diseases in the early stage. Health examination in Korea is divided largely into periodic health examination provided as a national health screening program and individual physical checkups. The advantages of the former include little economic burden on the examined and those of the latter include the freedom of the individual to select various examination headings depending on the individual's characteristics and preferences. With both examinations now being expanded, empirical analyses from various standpoints are needed. This study proposes to analyze traits of the examined and non-examined as shown in the facts and figures of the 1st and 2nd Korean Longitudinal Study of Ageing (KLoSA), thereby make the determinant factors clear leading to the acceptance of the examinations, and analyze the effects of the examinations upon maintaining or moving to healthy lifestyle. It was confirmed that demographic features such as gender and age, socioeconomic features such as the level of education, place of residence and household income, physical and mental state of health such as chronic disease and dementia, and daily living habits are significantly related with whether to accept physical examination. It is also confirmed that physical examination leads to non-smoking, regular physical exercises and regular dietary habits. It is suggested that, to enhance effects of health examinations, follow-up management programs making use of results of health examinations be further expanded, and the national health screening program be more actively put into operation for the bracket lying in the blind spot of the program.

The purpose of this research was to survey and compare the status of science preference of elementary school students with that of middle school students. Preference for science was defined theoretically. According to theoretical model, a questionnaire was developed with piloting and consisted of three parts. First part was for background information, second part, for measurement of science preference and third for measurement of the relevant factors of science preference. The questionnaire was modified for primary school students. In July 2002, the questionnaire was administered to one class per grade of randomly selected 8 elementary and 8 middle schools all over the country and analyzed result of collected 696 elementary school students and 819 middle school students. Middle school students' science preference was low compared with elementary school students, especially in 'emotional response and 'valuational comprehension'. The preference for science became lower especially from 4th to 5th grade and from 8th to 9th grade. The differences of mean science preference were significant by gender. perception of science achievement. and future career choice. The average of science preference relevant factors of middle school students also became lower than elementary students, especially in 'educational factor'. Multiple regression analysis on the science preference showed that important factors were personal ability, the personal traits, rewards in school science and contents of school science, slightly different in elementary and secondary school. The way to promote students' preference for science was suggested on the analysis result.

While entrepreneurship is touted as an opportunity for women to exploit opportunities that are often not available in the traditional workplace, the rate of participation in entrepreneurship is lower for women than it is for men. What remains relatively unclear are the reasons that make this so. This regional study addresses this deficiency by examining two lines of thought related to entrepreneurial adoption: (1) the personal traits thought to contribute to entrepreneurship, and (2) the rational decision making processes that are believed to form a basis for entrepreneurial endeavors. My results find men and women to be different in both respects, with ambiguity tolerance, internal locus of control, perceived effectiveness of entrepreneurship, and having an entrepreneurial parent all positively predicting entrepreneurial intention for men. For women, perceived effectiveness of entrepreneurship and achievement motivation predict entrepreneurial intention. Women also rate the potential reward of entrepreneurship as significantly lower than do men, possibly because women entrepreneurs objectively face more obstacles than men with regard to obtaining financing and other stakeholder relations.

Objective: The aims of this study are to investigate the total volume of prescribed medicines against Alzheimer's disease (AD) and the trends of usage by analyzing the claims-data from the Korea National Health Insurance Service. Method: The demographic and claims-data were included the major AD treating medicines such as donepezil, galantamine, rivastigmine and memantine, and analyzed during the period of 2010~2012. The assessing criteria were gender, age, habitation, types of medical institution, code of ingredients, outcomes of treatment, volume and amount of claims, and the numbers of patients with dementias. After trimming the data, it were analyzed by the market size, demographic traits, characteristics of medical service, characteristics of each anti-AD medicine, etc. Results: Among the chosen 4 medicines, donepezil had the top prescription volumes. Most prevalent prescribing preparations of donepezil were conventional types. However, among the non-conventional types, oro-dispersible formulation is the fast increasing one in both volume and growth rate. This specialized preparations to improve both toleration and adherence, tend to being prescribed generally at the tertiary medical institutions. While the younger patients with mild-to-moderate AD mostly treated by expensive medicines in resident at the tertiary hospitals, the rest older patients with severe AD have been treated non-expensive one at long-term care facilities. Conclusion: AD is a chronic illness therefore, long-term use of therapeutic medications are highly important. If an anti-AD treatment was applied steadily in the earlier stages, it would be achieved not only improving the quality of life of patient but also reducing the expenses in the medical and nursing cares. As the socioeconomical impacts of AD is expanding, healthcare professionals need to aware the importance of pharmacotherapy and to improve sociopolitical fundamentals.

This study is for finding out Career-barrier of the disabled, and for analyzing the effect of Career-barrier on the dysfunctional career-thought. For this study, 180 disabled people were surveyed. The results are as follows; First, the career-barriers that the disabled people perceive are in order; lack of occupational information, lack of social support, low self-concept clarity, low self-efficiency, and conflict with significant-others. Secondly, difference of career-barrier, caused by the traits of the disabled, has influenced the lack of self clarity and occupational information. In addition, among the types of the disabilities, it is proven that the psychological disability highly correlated to the social support, unlikely to gender difference and job experience. Thirdly, the most influential reason on the decision-making confusion for finding job among the sub-variables of dysfunctional career-thought were; low self-concept clarity, conflict with significant-others, and low self-efficiency. While it turned out that the most influential career-barrier on the performance anxiety for disabled people were low self-efficiency and conflict with significant-others.

The purpose of this research is to critically analysis the applying trend of the successful aging research on the baby boomers Generation. Research method is qualitative content analysis and this study was analyzed by concepts, factors, heterogeneity and variety of generation. The results of the analysis on 124 domestic articles on the journals on the successful aging from 2000 to 2016 are as follows: most of concepts in researches are about economic problems. In a research model, social environmental factors are barely considered. Heterogeneity and a few studies showed identities and varieties of generation. Based on these results, several suggestions are presented; First, consideration about the concepts of successful aging On a broad range is required. Secondly, concepts and influence factors should be clearly identified. Third, factors related to life itself in aging and macro social environment than factors of individual unit focused on economic value should be used. In addition, new age-old cultual value should be discussed to understand the Inherent traits of baby boomers. Lastly, studies to discuss varieties which are caused by age and gender of the baby boomers are needs to proceed.
