Purpose - This paper empirically investigates the relationship between firm productivity and importing intermediate inputs in the Korean manufacturing sector. Design/methodology - This paper tests the two related hypotheses on the relationship between importing and productivity for a sample of Korean manufacturing firms. We test the self-selection hypothesis by comparing pre-entry levels of productivity between importers and non-importers. We test the learning-by-importing hypothesis by employing propensity score matching with differencein-differences approach. Findings - Future importers are more productive than future non-importers years before they start to import, which supports the self-selection hypothesis. In contrast, there is no strong evidence for learning-by-importing. Originality/value - This paper is the first study to explore the relationship between importing and firm-level productivity for Korean firms. The results have an important implication on trade policies to lower or raise trade barriers in imported inputs.

The subjects of this study on self-awareness were sixty-four 8- to 30-month-old infants. They were tested with the "Behaviors Observed in Mirror Conditions" (Lewis & Brooks-Gunn, 1979; translated by Jong Moo Kim, 1989). Analyses were by descriptive statistics and ANOVA. Most infants responded when they saw their reflection in the mirror, and their self-awareness increased with age. Most infants under 17 months didn't respond before and after rouge was painted on their noses, but by 18- to 23-months, they started to show a response. Most of the infants older than 24 months noticed something unusual and tried to rub the rouge off when they saw their reflection. This study provides evidence that infants begin to show self-awareness after 18 months of age, and this self-awareness is well developed after 24 months of age.

Osteoarthritis is one of the most common chronic degenerative disease and prevalent among women in rural area. A variety of self-management programs for arthritis patients have been developed and administered, however the effectiveness and adherence to the program including arthritis exercise are found to be low. The purpose of this study is to design intervention Arthritis Self-Management Program with Tai Chi (ASMP-TC) through identifying and analyzing attributes influencing adherence exercise behavior in Korean older adult women with arthritis in rural area. For this, the existing and relevant evidence on arthritis self-management including exercise intervention were investigated, and then this study describes well-designed arthritis self-management program to provide the credibility and validity necessary for its interventions. In addition, this study try to propose a self-management program model of Tai Chi exercise for rural older adults to improve adherence based on the primary health care facility, which is vulnerable area in Korea.

Purpose: The purpose of this study was to investigate the effects and characteristics of health care programs for pregnant women with gestational diabetes mellitus (GDM) in Korea. Methods: This study was conducted according to the Cochrane Collaboration's systematic literature review handbook and the Preferred Reporting Items for Systematic Reviews and Meta-Analyses reporting guideline. We searched eight international and domestic electronic databases for relevant studies. Two reviewers independently selected the studies and extracted data. For each study, information on the research method, participants, characteristics of the program, and results were extracted using a previously established coding table. The National Evidence-based Healthcare Collaborating Agency's risk of bias assessment tool for non-randomized studies was used to assess the risk of bias of the included articles. A qualitative review of the selected studies was performed because the interventions differed considerably and the measured outcomes varied. Results: Out of 128 initially identified papers, seven were included in the final analysis. The risk of bias was evaluated as generally low. Health care programs for pregnant women with GDM showed positive effects on blood glucose control. Anxiety and depression were reduced, and self-management and self-care behavior, self-efficacy, and maternal identity improved. Conclusion: Our study provides clinical evidence for the effectiveness of health care programs for pregnant women with GDM, and its results can be used to support the development of health care programs for GDM. More well-designed research is needed on GDM, especially studies that deal with emotional stress and apply a family-oriented approach.

The purpose of this study was to investigate the impact of student assessment activities on claim and evidence formation in argument-based inquiry (ABI) for high school students. The participants of the study were 166 grade 10 students from six different classes in the same high school. The experimental group (84 students) was taught Argument-Based Inquiry with students' self and peer assessment activities. The comparative group (82 students) was taught without the activities. Over one semester students participated in five ABI programs that we developed. According to the analysis of the claim and evidence from groups, the experimental group had a significantly higher mean score than the comparative group. The result of analysis of students' assessment in the experimental group, the frequency about accurate and sufficient evidence revealed to be high and students assessed whether peers' claims fit with the evidence and whether peers' explanations of the evidence's validity was sufficient. Students' answers in the survey and interviews showed that the students though they could improve the accuracy of their ideas, appropriateness of their evidence, and the method of presenting evidence based on the assessment results.

Purpose: The purpose of this study was to explore self-management support experiences among breast cancer survivors. Methods: Individual in-depth interviews were performed for survivors who had treated breast cancer after completion of chemotherapy and radiation therapy. Data were collected from April 2014 to July 2014 and analyzed using phenomenological method by Colaizzi. Results: Five essential themes were found as follows: 1) Need for continuous help and support to maintain self-management, 2) Need for professional resources to carry out regular exercise, 3) Overcoming psychological difficulties through others rather than health care professionals, 4) Disappointment with time with and circumstances of health care consultation, 5) Dependence on means of media for health related information. Conclusion: The results might contribute to an understanding of self-management support experienced by breast cancer survivors in Korea. It is suggested that evidence-based program for self-management support should be developed and applied to nursing intervention for breast cancer survivors.

Purpose: The purpose of this study was to examine the effects of microteaching for student health educators. Methods: Subjects included 43 students in the nursing department of "H" university. In order to measure the degree of self-efficacy and speech anxiety at pre-treatment and post-treatment, subjects in the experimental group underwent training in microteaching. Results: No significant difference of variance in self-efficacy and speech anxiety was observed between subjects in the experimental group and those in the control group. However, self-confidence, a sub-domain of self-efficacy, showed a significant increase from pretest to post-test. In addition, speech anxiety measured during the post-test showed improvement, when compared with that of the pretest. Conclusion: Findings of this study provide preliminary evidence that microteaching may result in improved speech behavior.

Purpose: This study was done to assess the effects of a self-help intervention on clinical, lifestyle and psycho-social outcomes in patients with Type II diabetes. Methods: Eligible adults with Type II diabetes were randomly assigned to either the intervention group receiving the diabetes self-help or the control group receiving usual care. Of the 36 patients who completed the study, 15 were in the intervention group and 21 were in the control group. The self-help group consisted of six weekly sessions covering aspects of diabetes self-care and using continuing education, discussion, and structured social activities. Outcomes included changes in glycemic control, knowledge, self-management behaviors, diabetes-related self-efficacy, and health-related quality of life. Analysis of covariance was used to compare outcomes between the groups, adjusting for baseline measures. Results: After the six week intervention, significant improvements from the baseline were observed in the measurements of self-management behaviors, diabetes-related self-efficacy, and health-related quality of life for the intervention group. Conclusion: The findings provide preliminary evidence that a diabetes self-help group intervention can benefit diabetes patients in self-management behaviors, diabetes-related self-efficacy, and health-related quality of life. However, larger longitudinal studies are needed to determine the most efficacious self-management methods to sustain long-term glycemic control and psychological well-being.

The purpose of this study is to examine types and characteristics of self-regulation which explain how individual diabetic patients determine their behavior in terms of diabetes management. Based on the results, we proposed the management method of the diabetic patients. As a method of analyzing the subjectivity of each item, a Q method study was used. There were 38 subjects who were treated with oral drugs or insulin injections, but not currently hospitalized. And 40 statements in Q samples were classified in the form of a normal distribution using a 9-point scale. Research results regarding self-regulation in diabetic patients, type 1 is evidence-based compliance, type 2 is crisis responding denial reaction, type 3 is information-based orientation to relationship, type 4 is independent practice, and type 5 is willingness deficit impulse reaction. Therefore, for effective management of diabetic patients, it is necessary to understand the characteristics of each type of self-regulation and develop a program that reflects motivation for diabetes management, improvement of confidence, and countermeasures for negative emotions related to disease.
