In this study, elementary students' science communication competence was investigated based on the grammatical features expressed in their language-use in classroom discourse and science writings. The classes were designed to integrate the evidence-based reasoning framework and traditional learning cycle and were conducted on fifth graders in an elementary school. Eight elementary students' discourse data and writings were analyzed using lexico-grammatical resource analysis, which examined the discourse text's content and logical relations. The results revealed that the student language used in analyzing data, interpreting evidence, or constructing explanations did not precisely conform to the grammatical features in science language use. However, they provided examples of grammatical metaphors by nominalizing observed events in the classroom discourses and those of causal relations in their writings. Thus, elementary students can use science language grammatically from science language-use experiences through listening to a teacher's instructional discourses or recognizing the grammatical structures of science texts in workbooks. The opportunities in which elementary students experience the language-use model in science learning need to be offered to understand the appropriate language use in the epistemic context of evidence-based reasoning and learn literacy skills in science.

Objective : The purpose of this study was to analyze the effects of dual-task training on stroke patients. Methods : We searched the databases such as NDSL, RISS, PubMed, CoChrane and EMBASE for publications in the past decade. Finally, 10 papers were selected. Qualitative assessment was performed according to the traditional single-layer evidence model, and meta-analysis was performed using the Comprehensive Meta Analysis 3.0 program. Results : The quality level of each of the 10 selected papers all correspond to I and II in the traditional single-layer evidence model. The motor tasks that constitute dual-task training comprised walking or balancing tasks in 7 articles and the motor tasks related to upper extremity were selected in 3 studies. The effect sizes for ADL function and Cognitive function were 0.65 and 0.64 (medium size effect) respectively. Moreover, the effect sizes of Lower extremity and Upper extremity motor function were 0.34 and 0.22 (small size effect) respectively. The effect size of ADL function and Cognitive function were statistically significant p<0.05). Conclusion : This study confirmed that dual-ask training can be a useful intervention technique for recovering a stroke patient's ability to perform daily activities and cognitive functions. This could be used as a helpful data when selecting appropriate intervention for stroke patients in the clinical setting.

This study was conducted to examine the effects of a smart home (electronic control unit, ECU) on the performance and satisfaction of activities of daily living of wheelchair users. A total of 15 wheelchair users (10 patients with spinal cord injury and 5 patients with stroke) were investigated. Smart homes were equipped with ECU technology, which consisted of automation of furniture and products. The products and facilities were integrated and controlled by a smart device or voice. Performance and satisfaction of activities of daily living were measured by the Canadian Occupational Performance Measure (COPM) before and after residence in a smart home. All participants showed a higher COPM (performance score ${\geq}3$, satisfaction score ${\geq}4$) during residence in a smart home compared to residence in the current home. In addition, the COPM scores differed significantly before and after residence in a smart home. These results provide evidence of the applicability of smart homes based on high technology. However, additional studies of more smart home participants should be conducted to improve the quality of the results.

Objective : The purpose of this study was to investigate the effect of telerehabilitation on executive function, activities of daily living, instrumental activities of daily living, and occupational performance in stroke patients. Methods : The participants of this study were 30 outpatients with stroke residing in community. Both groups underwent the intervention 3 times a week for a total of 18 sessions. For the experimental group telerehabilitation was administered at home to only fifteen participants in the experimental group schedule, and it was supervised by the caregiver. Fifteen people in the control group underwent only the traditional occupational therapy. Executive function and instrumental activities of daily living were evaluated using the Korean version of the Executive Function Performance Test (EFPT-K). The basic daily activities of living were assessed using the Modified Barthel Index (MBI). The Canadian Occupational Performance Measure (COPM) was used to evaluate the client-centered occupational performance. Results : After the intervention, the experimental and control groups showed improvements in executive function, instrumental activities of daily living and occupational performance. Occupational performance improved more significantly in the experimental group than in the control group. Conclusion : Telerehabilitation and occupational therapy positively affect executive function, instrumental activities of daily living and occupational performance of patients with stroke. We suggest that telerehabilitation combined with occupational therapy is more effective in improving the occupational performance of stroke patients.

This study aimed to develop a scale to measure the family strength of single-parent families. We analyzed the everyday life and demands of single-parent families using the theory of family strength to draw 78 items that encompass family basis, relationships, roles, social networks and family culture. Using a sample of 286 single-parent families through an online survey platform, we examined the factor structure of the items and selected 48 items based on the results of the factor analysis. Reliability, criterion and construct validity were also examined. The final scale comprised of five domains ; basis, parents' role, work-life balance, social network, lifestyle and household management. This scale can be used as an assessment measure of the family strength of single-parent families for consulting, case management and suggesting various programs in the field. This merit will help enhance the quality of programing for single-parent families at the Healthy Family Support Center and the development of family strength scales for various types of families.

The rapid aging of society has led to a surge in cognitive dysfunction in the elderly. As there is limited evidence for the development of dementia in medicine, a shift in focus on prevention strategies using bioactive compounds in food is required. This systematic review evaluated the effects of various bioactive compounds on age-associated cognitive decline. The literature was searched for terms related to bioactive compounds in cognitive decline and article selection was limited to clinical randomized controlled trials for a single bioactive compound. We identified 21 studies that evaluated the strength of the evidence. ω-3 fatty acids and vitamin B presented a strong evidence level, whereas vitamin D and E, anserine/carnosine, and chromium were defined as having moderate levels of evidence. ω-3 fatty acids relieved cognitive decline and reduced amyloid β-related protein accumulation. Vitamin B decreased homocysteine levels, which is accompanied by alleviation of cognitive function. In conclusion, ω-3 and vitamin B have the potential to improve age-associated cognitive decline.

쾌적한 의생활을 영위하기 위해, 인간의 제반 특성에 적합한 의복 설계에 관한 연구가 활발히 전개되고 있다. 기존 연구에서는 주로 인체 인자에 근거하여 의복 원형 연구가 이루어졌으나 인간 특성에 적합한 의복의 설계를 위해 인체 인자와 함께 의복 인자를 병행한 연구의 필요성이 대두되고 있다. 특히 의복 소재의 경우, 성유과학의 발달로 다양한 의복 소재가 개발되고 있음에도 불구하고 대부분의 의복 원형 연구에서는 광목으로 제한되어 연구가 행해지고 있는데, 광목이 원형 연구시 동작에 따른 체표 변화에 대응하기 위한 여유분으로 정확히 산출할 수 있다는 특징이 있기는 하지만 이로 인하여 의복 원형의 여유 분 설정에 소재의 특성에 따른 차이에 관해서는 아직 까지 많은 연구가 진행되지 못하였다. 이에 본 연구 에서는 최근 마른 체형의 선호와 함께 유행하고 있는 신축성 소재를 이용한 슬랙스 원형에 대하여 연구 하였다. 본 연구는 소재의 신장특성과 의복 설계와의 관계에 대한 기초 자료로써 활용될 수 있을 것이며, 또한 슬랙스 원형에 대한 연구를 보다 다양한 소재로 넓힘으로써 원형의 활용도를 높힐 수 있을 것으로 기대한다.
