The purpose of this study aimed to develop the misutkaru water drink intake program that was possible to compare the effects of misutkaru drink on relieving constipation and physiological measurementson relieving constipation of the patients with hemodialysis. This study was non-equivalent control group pretest-posttest design with 42 patients in a general hospital in S city, Korea. During the experiment, the participants had to drink misutkaru water in the morning and past the 7 days after intake as constipation assessment scale, potassium and phosphorus were measured. The data were examine using t-test, Fisher's exact test, paired t-test. After misutkaru drinking intervention, constipation (z=-2.66, p=.002) decreased significantly improvement. This suggests that misutkaru water drinking intervention improved constipation in patients with hemodialysis.

As fierce competition is expected in the wearable devices marekt, it is needed to develop a technology planning that can increase consumer acceptance. This study aims to provide implications for technology planning of wearable devices by examining consumer preferences for the devices. For this purpose we employed a conjoint analysis. In the process of the analysis, we considered the trend of anticipatory standardization for wearable devices in an attempt to improve objectivity of analysis whilst many previous studies relied on focus group interview. For the anticipatory standardization information, we utilized liaisons and projects of wearable devices at International Electrotechnical Commission, and we designed a conjoint survey on the basis of the information. We conducted an online survey, and a total of 229 individuals responded to our survey. The result of conjoint analysis shows that main use and enhanced features were more important attributes than the others were. However, consumer preferences for detailed levels of each attribute were different by gender and age groups. This result implies that technology planning of wearable devices require distinct approaches by consumer segments.

Using data sets from the Korean Labour and Income Panel Study (KLIPS) for the period 2003-2015, this study shows that wages of nonunion workers are positively related to the percentage of unionized workers in the same geographic region. A 10 percentage point increase in a region's union density is associated with a 4.9 percent increase in the region's average wage of nonunion workers. It is also shown that this positive spillover effect is observed for various subgroups of nonunion workers, including women, youth, low-educated workers, small firm employees, and those employed under nonstandard work arrangements. In contrast, the average wage of union workers is found to respond insignificantly to changes in a region's union density.

Despite of the various advantages of modular construction method and the continued growth of related markets, it is difficult to activate them because no specific system has been established in Korea. Accordingly, this study derived improvement areas and tasks for activating modular construction methods through existing literature reviews and preliminary surveys. Then, AHP analysis and expected utility evaluation were conducted for expert groups to derive priority for improvement areas and tasks. In addition, opinions of enterprise and architectural research were compared and analyzed, and the analysis results suggested the direction of policy establishment and system improvement. This study is expected to be used as a basic study for policy decision-making to activate modular construction method.

This study utilizes PhotoVoice, a qualitative research method, to explore the life experiences of retirees by age in depth and derive the social welfare implications required for successful aging of retirees. Two participants in the study were selected in their 70s, 60s, and 50s, and 24 photos, explanations, 44 stories, and 92 data collected through group activities and personal interviews were analyzed. With the perception of successful aging, those in their 70s were "Preparing for a High Level of Social Responsibility and Dignity," those in their 60s were "Life of Social Responsibility and Service with Embarrassment and Boeun," and those in their 50s were "Life of Self-reliance with Economic Stability and Consideration." In order to prevent social problems for retirees with longer old age, research and social welfare policy support for their social jobs and volunteer positions are urgently needed, and the sooner the preparatory education is implemented so that they can prepare enough. This study is significant in that it played an important role in presenting basic data for the preparation of social welfare alternatives for retirees.

The purpose of this study was to compare the psychological state of nursing students according to classes in the face-to-face and non-face-to-face situations during COVID-19. Subjects were randomly expressed. As for the analysis method, the difference in the scores of the dependent variables between the two groups was analyzed by an independent t-test. As a result of the study, The degree of depression and anxiety between the two groups was higher in face-to-face students(8.16±9.48, 8.20±9.93) and non-face-to-face students(7.08±8.38, 6.53±8.23) but not statistically significant (t=1.143(.254), (t=1.728(.085)). These results are used for the basis for preparing a program for psychological relief for students participating in face-to-face classes, and a repeated study on psychological depression and anxiety among students is suggested in the future when social distancing is prolonged.

This study was a randomized before-and-after design of 17 subjects in the experimental group and 17 subjects in the control group to investigate the effects of listening to relaxing music on the mood state and autonomic nervous system, that is, heart rate of hospitalized patients with mental illness. The collected data were analyzed with SPSS V15.0. There was a statistically significant difference between the two groups in mood state and autonomic nervous system, that is heart rate and the effect of listening to relaxation music was objectively verified(<.05). among the subdomains of mood states, tension(<.00), depression (<.00), vitality (<.03), fatigue () <.01), excluding anger (>.39) and confusion (>.33) showed a significant difference, proving that it is an effective intervention method applied to hospitalized mentally ill patients. In the future, we would like to suggest long-term intervention research and development and application, and research on the effect of mood change and heart rate using individual preferred music.

Data science is a discipline comprised of the academic fields of statistics, computer science, information technology, and domain knowledge. It analyzes data and derives meaningful results using complex technologies. Data science, along with artificial intelligence, is a core technology of the 4th industrial revolution; consequently, universities and companies worldwide are actively developing programs to develop data scientists who require high levels of expertise. In line with this undertaking, the field of elementary education has recognized the importance of data science education and so various studies have been conducted to develop curricula designed to help students understand how to use data. This paper proposes a curriculum for the purpose of educating elementary school teachers who are mostly non-majors in the computer field about data science. Satisfaction analysis was conducted based on questionnaires collected from students to analyze the effectiveness of the data science education proposed in this paper.

This study analyzes how the health program is implemented by political and economic factors in the case of Minga Ambiental program in Paraguay. In the field of critical medical anthropology, the practice of health care programs explains that socio-cultural and political and economic factors can be the main variables besides the primary purpose of preventing and eradicating the disease. In the same vein, this study also analyzed how community-based health programs operate by various external factors. As a result, the Minga Ambiental program is a health program called Dengue Fever, which has been tended to be sustained and expanded by various actors, including politicians and corporations in countries and communities, despite concerns about effectiveness. In this case, this study found that health programs can be operated by political and economic relations different from their original purpose, and are intertwined in various social contexts by various actors in constructing health programs.
