In the near future, the multicultural families are expected to be the majority of population living in the rural area, which is an aged and small-scaled society. Moreover, they are expected to have an important role in sustaining the culture of agriculture and a rural community. Therefore, it is very important for them to adjust and settle urgently as well as to develop a policy and social services for the adjustment and settlement. The purpose of this study is to identify different aspects of the participation in agricultural, social, and job activities of married immigrant women in a Korean rural area as well as to investigate the change of life satisfaction resulting from the l activities. The following findings were established from this study. First, married immigrant women participate in local social and agricultural activities in a Korean rural area more frequently than in their own country. However, the frequency of their participation in job activity in a Korean rural area is lower than in their own country. Second, the main factor that prevents married immigrant women from participating in agricultural activity in a Korean rural area is to carry out childcare, household chores, and farming at the same time. Their low participation in social activity and job activity mostly results from their lack of fluency in Korean. Third, married immigrant women score higher in the change of life satisfaction after participating in social activity and job activity than in agricultural activity.

Prolonged sitting can contribute to low back pain. The lumbar taping can be applied to correct the sitting posture. This study aimed to investigate the effect of lumbar taping on lumbar kinematics and the muscle activities of multifidus (MF) and internal oblique in the individuals with nonspecific chronic low back pain (NSCLBP) as they type for 30 minutes. Nineteen subjects with NSCLBP (9 people in non taping group and 10 people in taping group) were recruited. Lumbar taping was applied to the taping group before typing. Both groups started typing in a neutral sitting position with their feet on the floor. The change of posture and S2 posterior tilting (S2P) were measured to investigate kinematic data. Three sensors were attached on T12, L3, and S2 to identify the change of posture. Surface electromyography was used to measure the muscle activities. Palpation meter was used to standardize the angle of pelvic tilt in sagittal plane before typing. All instruments were used to measure each data before and after typing. Independent t-test was used to compare the changing values of lumbar kinematics and muscle activities before and after typing between both groups. The changing values of S2P and change of posture of L3 and S2 were significantly smaller in the taping group compared to the non taping group (p<.05). The changing value of muscle activities of MF between before and after typing was significantly smaller in the taping group compared to the non taping group (p<.05). In conclusion, the lumbar taping during the 30-minute typing task can be applied to maintain correct sitting posture in the lumbar and pelvis and to maintain activation of MF.

Purpose: This paper provides an idea on the future prospect for change in steps of the six sigma DMAIC project under the environment of the 4th industrial revolution. Methods: First, the purpose and activities required in each step of DMAIC are reviewed. Next, activities are reviewed together with tools and techniques, considering the purpose and the environmental changes of the 4th Industrial Revolution. Finally, the best approaches for achieving the purpose are prospected to get an idea on future change. Results: The purpose of each phase of DMAIC is expected to remain unchanged. But activities, techniques, or methods will be replaced with more effective and efficient ones. Also, many activities may possibly be executed by a system instead of people like BB, GB or team members. Moreover, DMAIC may not be a project any more but a routine job of the system in the future. Conclusion: Under the environment of the 4th industrial revolution, many activities including analyzing various types of data and extracting valuable information, will be executed by a system with proper algorithms instead of people. And six sigma improvement projects may be intrinsic parts of the system and may not exist as separate projects any more.

PURPOSE: This study examined the impact of functional group cooking activities on the depression and interpersonal relationships of stroke patients with psychological impairments. METHODS: Ten stroke patients were divided into an experimental group and a control group and participated in this study from October 2015 to January 2016. The experimental group and control group each comprised five stroke patients. Traditional occupational therapy was given to the control group and the experimental group undertook the cooking activity. Depression changes were measured using the Beck depression inventory (BDI), and the interpersonal relationships were evaluated using the relationship change scale. RESULTS: The findings indicate that, first, there was a significant difference in the depression changes in both groups before and after the intervention. Second, after the intervention, the interpersonal relationships of the experimental group showed a higher mean change value and were significantly higher than the control (experimental: 22.4, control: 4, p < .05). In contrast, there was no change in the depression status between the two groups. CONCLUSION: Functional group cooking activities appear to be more effective in improving interpersonal relationships than traditional occupational therapy. However, to establish that functional group cooking activities are linked to improvements in the depression status and interpersonal relationships of the participants, further studies would be needed with more extensive group activities and larger sample sizes.

The purpose of this study is to suggest the modification of activities to introduce the nature of science in earth science classrooms. A small modification can turn ordinary textbook activities into the nature of science activities. Since earth science could provide a good basis for the tentative, creative, and socially and culturally embedded nature of science, as well as appropriate understanding about scientific methods, careful modification of earth science activities could be effective for students to understand the nature of science. Considering which aspects of the nature of science are appropriate, along with the possible change in the activity, teachers will be able to modify textbook activities effectively. An example modification of H-R diagram activity was also suggested.

The purposes of this study were to investigate children's preconception about matter, to analyze children's conceptual change. of ,matter by science learning activities, and to investigate understanding possibility about mallet The subjects of this study were the second grade students of an elementary school and science learning activities were conducted to 2 boys and 3 girls for investigating their conceptual change. Video tape recording, interview, drawing pictures and writing statements were used to collect data. The concepts in this study were properties of matter, states of matter, uses of matter and origins and changes in matter. Then, the collected data were analyzed by the way of categorization and qualitative method. The conclusions of this study are as follows: science loaming activities were effective for changing misconceptions of matter to scientific concepts. Conceptual changes of high achievers happened easier and more than of low achievers. In the ideas about matter, some children had supernatural ideas and animism, which were most second grade students' characteristics.

This study was performed to investigate the change of biologically functional compounds and antioxidant activities in Hizikia fusiformis with drying methods. As biologically functional compounds, the contents of minerals(K, Ca, Ma, Mg, Fe, Cu, Mn and Zn), vitamins(vitamin C, ${\beta}-carotene\;and\;{\alpha}-tocopherol$) and total polyphenol were analyzed. And antioxidant activity was determined through free radicals(DPPH radical, superoxide anion radical, hydroxyl radical and hydrogen peroxide) scavenging activity and linoleic acid peroxidation inhibitory activity. The contents of minerals were not affected by drying methods however vitamins and total polyphenol were lost more by sun-drying than other drying methods studies. Total polyphenol was preserved by freezing-drying than other drying methods studies, resulting in high antioxidant activities.

To determine the regulatory mechanism of phenylethanolamine N-methyltransferase (PNMT) in the adrenal gland and in central nervous system, we observed the change of enzyme activity and mRNA level of PNMT in the adrenal gland, the brain stem, and hypothalamus of rats, which were injected with two neuroleptic agents(reserpine and haloperidol ). Reserpine depleting catecholamines in presynaptic vesicle increased PNMT activities in the adrenal gland and the brain stem to 150% of the control in time-dependent manner, but not in the hypothalamus. Haloperidol blocking dopamine receptor decreased PNMT activities in the adrenal gland and the hypothalamus, but not in the brain stem. Thus, the results indicate that catecholamines inhibit synthesis of epinephrine in the brain stem and the adrenal gland, and that dopamine stimulates synthesis of epinephrine in the hypothalamus and the adrenal gland. In addition, since the change of mRNA levels were nearly in accordance with the change of activities, the transcriptional regulation of PNMT is considered the mechanism of the regulation of epinephrine neuron.

This study was to evaluate the walking speed of elderly people by using the travel route big data collected by travel diary and smart phone application. We analyzed the change of walking behavior in the residential street environments of the elderly whether they had a company or not. We interpreted the meaning based on previous studies. In addition, the characteristics of elderly people's use of the residential street environment were analyzed by comparing the change in spatial speed according to the companion. The result reveals that the usage patterns of the residential street environments change depending on whether they were accompanied or not. First, the elderly tend to do more social activities while walking alone than when they were accompanied. When they were accompanied the social activities occur in empty lot near the residential area. However, the social activities of the elderly occur in open space such as neighborhood park or playground while walking alone. Finally, This study has strength that it empirically analyzes the elderly's walking behavior and usage paths in small outdoor spaces, including residential streets.
