Purpose: The purpose of this study was to develop a home-based self-management support intervention (SMSI) for enhancing pulmonary rehabilitation (PR) in patients with chronic obstructive pulmonary disease (COPD) in Korea. Methods: This methodological study was conducted by following these 4 steps: constructing the preliminary draft of a home-based SMSI from existing recommendation and a literature review on PR and self-management interventions; testing content validity with 6 experts in COPD; exploring clinical applicability of the intervention by applying it to 4 COPD patients; determining the final intervention. Results: The final intervention included 4 components and contents identified from the literature review as essentials for self-management of COPD patients: education; exercise training and practice including breathing, muscle strengthening and aerobic exercises; cognitive behavioral strategies including informative self-decision making, collaborative goal setting and supportive advice; and action planning for exacerbation. The intervention was designed to be run by a trained nurse and had 8 weekly sessions consisting of three 60-minute face-to-face sessions and five 20-minute phone-call sessions. Conclusion: The intervention developed in this study incorporates essential components of self-management, i.e. action plan and cognitive behavioral strategies, and will contribute to enhancing and maintaining effects of PR by increasing self-management in COPD patients.

본 연구는 팀 중심의 과제 수행이 요구되는 종합설계과목의 협동학습에서 스스로에게 영향력을 행사함으로써 자율성과 책임감을 강조하는 셀프 리더십이 팀웍과 어떤 관계를 갖고 있는지를 조사하기 위해 수행되었다. 그 결과, 셀프 리더십은 팀웍과 유의미한 상관관계를 나타냈고, 셀프 리더십이 높은 학생들의 팀웍이 셀프 리더십이 낮은 학생들의 팀웍보다 더 높았다. 또한 셀프 리더십의 여러 전략들 중에서 특히 인지적 전략(자연보상을 주는 활동을 일에 도입하기, 일의 좋은 면에 초점 맞추기, 자연보상의 분별)이 팀웍에 가장 큰 영향을 미치는 요인으로 확인되었다. 이러한 결과를 종합해볼 때, 공학교육과정에 셀프 리더십의 인지적 전략들을 학습할 수 있는 프로그램을 도입하는 것이 도움이 될 것으로 판단된다.

In the last 20 years, educators have made significant advances in their thinking about how students learn and what it is that teachers ought to teach. They attempted to teach thinking s kills and designed instructional programs to facilitate learning. The purpose of this study was to review metacognitive approaches in reading comprehension instruction, and to provide some practical implications to school teachers. First, this study reviewed the concept of metacognition. Metacognition can be divided by metacognitive knowledge and metacognitive experiences. Metacognitive knowledge consists of knowledge or beliefs about what factors interact to affect the outcome of cognitive enterprises. Metacognitive experiences are executive control of one's own cognitive process, which include planning, monitorning and evaluating. Second, this study attempted to investigate the processes of reading comprehension in the metacognitively based view. Third, this study reviewed three kinds of reading comprehension instruction. In the metacognitive approaches, instruction is viewed as constructive process in which teachers and students mediate and negotiate meaning from the instructional environment. In order to enhance reading comprehension, teachers should use examples, explicit instruction, modeling, and elaboration to provide sufficient scaffolding to students. The scaffolding gradually diminishes as students learn to use and apply the reading strategies on their own. Also, students should be encouraged to attribute successful reading to the use of appropriate strategies.

This paper introduces a full duplex single secondary user multiple-input multiple-output (FD-SSU-MIMO) cognitive radio network, where secondary user (SU) opportunistically accesses the authorized spectrum unoccupied by primary user (PU) and transmits data based on FD-MIMO mode. Then we study the network achievable average sum-rate maximization problem under sum transmit power budget constraint at SU communication nodes. In order to solve the trade-off problem between SU's sensing time and data transmission time based on opportunistic spectrum access (OSA) and the power allocation problem based on FD-MIMO transmit mode, we propose a simple trisection algorithm to obtain the optimal sensing time and apply an alternating optimization (AO) algorithm to tackle the FD-MIMO based network achievable sum-rate maximization problem. Simulation results show that our proposed sensing time optimization and AO-based optimal power allocation strategies obtain a higher achievable average sum-rate than sequential convex approximations for matrix-variable programming (SCAMP)-based power allocation for the FD transmission mode, as well as equal power allocation for the half duplex (HD) transmission mode.

The purpose of this study is to find a way to improve digital textbooks for self-regulated learning by applying cognitive scaffolding designs to an elementary math digital textbook and examining the effectiveness of the system. Hence this study was conducted in two steps. First, a framework for scaffolding design was devised by examining the problems and difficulties students encounter when using a mathematics digital textbook. Second, after the digital textbook was revised by applying the scaffolding design frameworks, the effectiveness of the scaffolding framework was examined by comparing students' achievement levels in an experimental group and that of students in a control group. Seventy fifth-graders participated in this study. Students were divided into two groups: an experimental group and a control group. The students in the experimental group studied with the revised version of the digital textbook and the students in the control group studied with the original version of the digital textbook. The students received a pretest before the experiment. After the experiment, they took an achievement test and completed a usability questionnaire. The data were analyzed by ANCOVA with the SPSS Windows version. The results revealed that the students who used the revised program (to which design strategies for scaffolding were applied) showed higher levels of achievement than those who used the original version. In addition, students in the experimental group generally showed higher scores on the usability survey, which consisted of four sub-categories such as 'effectiveness', 'efficiency', 'satisfaction', and 'learnability'. There was a statistically significant effect on 'efficiency'. These results implied that scaffolding strategies were effective for mathematics learning through the use of an elementary digital textbook.

One second grader, Junsu, was observed 4 times before and after formal multiplication lesson in Grade 2. This study describes how solution strategies in multiplication problems develop over time and investigates awareness of the relation between situation and computation in simple measurement and partitive division problems as informally experienced. It was found that Junsu used additive calculation for small-number multiplication problems but could not solve large-number multiplication problems and that he did not have concept of mathematical terms at first interview stage. After formal teaching, Junsu learned a variety of multiplication solution strategies and transferred from additive calculation to multiplicative calculation. The cognitive processing load of each strategy was gradually reduced. Junsu experienced measurement division as a dealing strategy and partitive division as a estimate-adjust strategy dealing more than one object in the first round.

The study examined whether the relation between mathematics self-efficacy and mathematics achievement was partially mediated by the learning strategies, using latent growth model analyses. It was also examined the auto-regressive, cross-lagged (ARCL) panel model for testing the stability and change in the relation of mathematics self-efficacy and learning strategy over time. The study analyzed the first-year to the third-year data of the Korean Educational Longitudinal Survey (KELS). The result of ARCL panel model analysis showed that earlier mathematics self-efficacy could predict later learning strategy use. There were linear trends in mathematics self-efficacy, learning strategy, and mathematics achievement. Specifically, mathematics achievement was increased over the three time points, whereas mathematics self-efficacy and learning strategies were significantly decreased. In the analyses of latent growth models, the mediating effects of learning strategies were overall supported. That is, both of initial status and change rate of rehearsal strategy partially mediated the relation of mathematics self-efficacy and mathematics achievement. However, in elaboration and meta-cognitive strategies, only the initial status of each variable showed the indirect relationship.

Purpose: The purpose of this study was to identify the stress and the coping strategies in breast cancer patients and their spouses. Methods: The stress level was measured by the Stress Questionnaire of Andersson & Albertsson (2000). The coping strategies were measured by the modified Lazarus & Folkman's Ways of Coping Questionnaire. The data were collected by a survey sampling 49 couples from one hospital in Seoul. The data were analyzed by t-test, ANOVA and paired t-test. Results: There was no significant differences between the stress level of breast cancer patients and their spouses. The problem-focused coping of breast cancer patients was significant higher than their spouses. The cancer patients and their spouses used problem-focused coping mode more than emotion-focused coping mode. In the problem-focused coping mode, breast cancer patients used two coping strategies - 'seeking information' and 'cognitive reconstruction' - significantly more than their spouses. In emotion-focused coping mode, the breast cancer patients used one coping strategy, 'emotional expression', significantly more than the their spouses. Conclusion: Further study needs to attempt to develop nursing interventions that could improve positive coping strategies.

본 논문은 북한이탈주민들이 남한사회 정착에서 경험할 문화적 적응과정에 대한 이해를 증진시키기 위해, 북한 이탈주민들의 스트레스 대처양식을 조사 분석하여, 남한주민들을 대상으로 실시된 기존연구의 결과들과 비교 그 의미를 논의하였다. 상황적 특성에 따른 스트레스 대처방식을 측정하는 척도를 수정 사용하여, 다양한 스트레스 유발 원인(내부/외부, 영속/일시, 대인/개인)에 의한 가상 스트레스 상황에서 북한 이탈주민들의 대처방식(적극/소극, 접근/회피, 인지/정서/행동)을 조사하였다. 연구 결과에 따르면, 동일한 연구방법을 이용하여 남한주민들을 대상으로 기존의 연구결과(한성열, 허태균, 채정민, 김동직, 2001)에서 보고된 결과들, 즉 남한주민들이 스트레스 상황에 따라 선호하는 대처방식과 부분적으로 차이가 있었다. 예를 들어, 일시적인 요인에 의한 스트레스 상황에서는 우울 정도(CES-D의해 측정된)가 낮은 북한 이탈주민들이 적극적이고 접근적인 행동적 대처방식을 더 선호하였고, 외부적인 요인에 의한 상황에서는 적극적인 대처와 접근적인 대처를 더 선호하는 것으로 밝혀졌다. 더 나아가, 개인적인 또는 대인관계에서 비롯된 스트레스 상황에서 선호되는 대처방식에도 차이가 있었다. 마지막으로, 이러한 차이가 단기적으로 북한 이탈주민들의 적응과 장기적으로 미래의 통일과정에서의 심리적 갈등을 준비하는 관점에서 본 연구의 제안점과 한계점이 논의되었다.
