Objective Determine differences between faculty, residents, and nurses regarding night shift preparation, performance, recovery, and perception of emotional and physical health effects. Methods Survey study performed at an urban university medical center emergency department with an accredited residency program in emergency medicine. Results Forty-seven faculty, 37 residents, and 90 nurses completed the survey. There was no difference in use of physical sleep aids between groups, except nurses utilized blackout curtains more (69%) than residents (60%) and faculty (45%). Bedroom temperature preference was similar. The routine use of pharmacologic sleep aids differed: nurses and residents (both 38%) compared to faculty (13%). Residents routinely used melatonin more (79%) than did faculty (33%) and nurses (38%). Faculty preferred not to eat (45%), whereas residents (24%) preferred a full meal. The majority (>72%) in all groups drank coffee before their night shift and reported feeling tired despite their routine, with 4:00 a.m. as median nadir. Faculty reported a higher rate (41%) of falling asleep while driving compared to residents (14%) and nurses (32%), but the accident rate (3% to 6%) did not differ significantly. All had similar opinions regarding night shift-associated health effects. However, faculty reported lower level of satisfaction working night shifts, whereas nurses agreed less than the other groups regarding increased risk of drug and alcohol dependence. Conclusion Faculty, residents, and nurses shared many characteristics. Faculty tended to not use pharmacologic sleep aids, not eat before their shift, fall asleep at a higher rate while driving home, and enjoy night shift work less.

The ability to use information technology has become increasingly important as technological advances continue to sweep through the computing world, and education for improving computational thinking has become globally instituted. In South Korea, informatics subjects have been modified in the 2015 curriculum and are now compulsory in primary and secondary education. However, despite substantial financial investment and numerous studies promoting informatics education, there continues to be a serious lack of pre-service teachers capable of teaching computational thinking. This study investigated pre-service teacher programming education using App Inventor, their perceptions of App Inventor, and how use of the program affected teacher problem-solving abilities and self-efficacy. In the pre-test, the control group and experimental group showed no statistically significant difference; however, the post-test revealed that the two groups showed statistically significant differences in problem-solving skills and self-efficacy. The participants initially showed interest in using App Inventor; however, after practice-teaching and project-based learning, the participants demonstrated a growing negativity toward the program when they made errors and the functional limits of App Inventor became apparent. Although most participants stated that they would not use App Inventor in their classes, the positive statistically significant differences in problem-solving skills and self-efficacy indicate that this study could be utilized as a basis for building a teaching-learning program using App Inventor and creating an educational plan for teaching computational thinking.

This study examines factors that influence adolescents' political trust in Asian societies with special emphases on authoritarian orientations and corruption perception. Previous studies on adolescents' political trust have focused almost exclusively on Western societies. As a result, the impact of other cultural values that are specific to Asian societies, such as authoritarian orientations, on adolescents' political trust has received little attention in the existing literature. Moreover, situated within a socialization framework which argues that political trust is an extension of interpersonal trust, much prior work has ignored the role of adolescent evaluations of institutional performance in generating political trust. The data I use offer empirical evidence that both authoritarian orientations and institutional performance-especially its ability to curb corruption-are independent sources of political trust among Asian adolescents and that the trust-eroding effect of corruption is less salient among Asian adolescents adopting more authoritarian orientations. Additionally, the evidence also suggests that corruption perception is a more important factor than authoritarian orientations in shaping adolescents' political trust in more economically developed countries while the reverse pattern is found in less developed countries.

This study explores effects of two types of chatbots - voice-based and text-based - on Korean EFL learners' speaking competence and learner perception. Participants were 80 freshmen students taking an English-speaking class at a university in Korea. They were divided into two experimental groups at random. During the sixteen-week experimental period, participants engaged in 10 chat sessions with the two different types of chatbots. To take a close examination of effects on the improvement of speaking competence, they took the TOEIC speaking test as pre- and post-tests. Structured questionnaire-based surveys were conducted before and after treatment to determine if there are changes in perception. Findings reveal two chatbots effectively contribute to improvement of speaking competence among EFL learners. Particularly, the voice-based chatbot was as effective as the text-based chatbot. An analysis of survey results indicates perception of chatbot-assisted language learning changed positively over time. In particular, most participants preferred voice-based chatbot over text-based chatbot. This study provides insight on the use of chatbots in EFL learning, suggesting that EFL teachers should integrate chatbot technology in their classrooms.

Purpose: The purpose of this study is to analyze the perception that gynecological surgery patients have on Traditional Korean Medicine(TKM) treatment. Methods: We studied the perception of TKM treatment by questionnaire from August, 2008 to Febrary, 2009 in Kyung-Hee University East-West Neo medical center. A questionnaire was given to 180 women and 150 women answered. Results: Out of 150 women, 93 women(62%) had been given TKM treatment during the last 3 years, while 57 women(32%) hadn't. 53 women(35.5%) had taken herbal medicine within the last 2 weeks, while 97 women(64.7%) hadn't. 71 women(47.3%) reported that they had been given TKM treatment related to the causative disease for the operation, while 22 women(14.7%) hadn't. And 97 women(64.7%) indicated that they were willing to use TKM as a part of their postoperative medical care, 53 women(35.3%) indicated that they weren't. Conclusion: Many patients are willing to take TKM treatment as postoperative care. We need more accumulation of data for demonstrating the efficacy and safety of TKM treatment.

Focusing on the situation where there are not many actual users of VR / AR, this study, from the viewpoint of technology adoption and use, explores the adoption-and-use process of AR contents that can be easily accessed by using smartphones. As a result, the factors influencing the necessity of AR contents were 'enjoyment' and 'satisfaction', and other factors, such as 'innovativeness', 'the experience of using similar media', and 'the number of AR usage', did not have significant impact on the necessity of AR contents. In addition, as a result of verifying level differences in 'enjoyment', 'satisfaction' and 'necessity' according to the experience of using AR content, only the 'enjoyment' and 'satisfaction' showed that there are differences. In other words, it can be interpreted that the users in their 20s actively use AR content only when they expect to have fun and satisfaction. To sum up, this study can provide an important implication for understanding the tendency of early AR content users' perception and usage behavior.

This study is to research the use and the demand of the elderly generation that pursue economic ability and active lifestyle. The composition of the meals were "homemade meals" 65.3%, "homemade & convenience meals" 26.7% overall. For the "never miss a meal" category, 70-74 years old was 48.3%, over 80 years old was 60.0%. The elderly under 70 years old showed a high frequency in the use of alternative meals (p < 0.05) and the elderly with higher education used the alternative meals more frequently (p < 0.01). The rice-cakes, bread, tuna cans, Korean side-dishes, beverages, meat, cup-noodles and seafood as alternative meals are in the order of most frequency. Also, 96.0%, 59.0% and 46.5% of the elderly had experience in using "Ready to eat (RTE)", "Ready to heat (RTH)" and "Ready to cook (RTC)". The oldest group surveyed, the elderly at the age of 80 years old and above showed lower preference for "completely cooked state" but showed highest results in the "half-cooked state". This shows the difference between people's perception and the behavior that showed high frequency of 96.0% in the experience with "RTE". This can be inferred that the elderly needs the development of convenience food that is moderately packaged according to the newer lifestyle where the elderly live independent from their children. Moreover, there is a higher demand in the healthy convenience food, which means that there is a need for development in the quality of the convenience food that will allow more faith in convenience food by the elderly.

The purpose of this study is to verify effects between the place attachment and the place value in public libraries; and also to identify whether frequency and purpose of usage, length of residence, and website use play a moderating role in the influential relationship between users' place attachment and the perception of place value for public libraries. Users' place dependence affected the library's value positively(+) due to moderating effect of usage frequency of the library and the users' length of residence. In order to estimate the moderating effect by purpose of use, the groups were divided by purpose of library use and the relationship between place attachment and place value by groups were analyzed. However, website usage bore no effect on users' place attachment or perception of place value to their local library. This study showed that place attachment as an affective indicator on users is very useful variable to explain the value of libraries as a social and cultural place.

In this study, housewives' attitudes toward genetically modified foods (GM foods) and their willingness to purchase GM foods were examined. The findings of this study could provide useful information for consumer education and consumer policy development regarding GM foods. The specific purposes of this study were: (1) to examine consumers' attitudes toward GM foods, (2) to analyze the effect of the perception of GM foods and demographic variables on consumers' attitudes toward GM foods, and (3) to analyze the effect of the perception of GM foods and demographic variables on consumers' willingness to purchase GM foods. The questionnaire used in the survey was constructed by the author, based on existing literature. The survey was conducted with 1,100 housewives, and 723 of the completed survey forms were used in the final analysis. Frequencies, percentages, means, standard deviation, t-tests, ANOVA, Duncan-test, Pearson's Correlation, factor analysis, and discriminant analysis were employed for data analysis methods. Major findings are: (1) Consumers' attitudes toward GM foods consist of three factors, that are, attitude regarding potential danger, attitude regarding the use of GM technique on plants, and attitude regarding the use of GM technique on animals. (2) Consumers with a higher level of education tend to perceive GM food as more dangerous, whereas consumers with a lower level of education tend to accept more the use of GM technique on plants. (3) Consumers who tend not to consider GM foods as dangerous, and those who acknowledged benefits in using GM technique on plants are more willing to buy GM foods.
