본 연구는 범불안 성향의 대학생을 대상으로 주의편향 및 범불안 증상에 대한 주의 피드백 인식 및 조절 훈련의 효과를 확인하였다. 범불안장애 척도(GAD-7) 10점 이상 또는 펜실베니아 걱정 질문지 척도(K-PSWQ) 56점 이상이며, 주의편향을 나타내는 범불안 성향의 대학생 31명을 선발하여 주의 피드백 인식 및 조절 훈련(Attention Feedback Awareness and Control Training, A-FACT) 집단(n = 11), 주의편향수정(Attention Bias Modification, ABM) 집단(n = 10) 및 활성 위약 통제(Active Placebo Control, APC) 집단(n = 10)에 무선할당하였다. A-FACT 집단은 탐침탐사과제를 이용한 주의편향수정 훈련 시, 개인의 기저반응시간(Baseline Neutral Response time, BNR)을 기준으로 편향 여부에 대한 피드백을 실시간으로 제공받았다. ABM 집단은 기존 ABM 절차와 동일하며, APC 집단은 주의편향을 감소시키기 위한 프로그램이라는 안내는 주어지지만 피드백이 주어지지 않는 탐침탐사과제를 실시하였다. 총 8회기로 구성되어, 주 2회로 4주간 진행되었다. 주의편향수정 훈련의 효과는 주의편향점수(Attention Bias Score, ABS)와 GAD-7, K-PSWQ 및 상태 및 특성 불안 검사(K-STAI) 점수 변화로 평가하였다. 반복측정 변량분석 결과, A-FACT 집단은 ABM 집단과 APC 집단에 비해 ABS가 유의하게 감소하였으며, GAD-7, K-PSWQ 및 K-STAI 점수도 유의하게 감소하였다. 이는 주의편향수정 훈련 시 편향에 대한 피드백을 통해 편향의 여부를 인식시키고 이를 통한 주의의 자기 조절적 통제가 주의편향 및 범불안장애 증상 경감에 효과적일 가능성을 시사한다.

Background: The high sensitivity of individuals toward safety information in production activities, that is, attentional bias toward safety (ABS), can positively predict safe behaviors. It has become a hot topic in current organizational safety behavior research. However, there is no literature on its modification method. Methods: Based on the modified dot-probe task, we designed a modification training method of ABS. The training method required subjects to respond to the location of detection points that presented after safety stimulus and neutral stimulus pictures. Subjects' attentional bias values of safety and neutral pictures were measured during the experiment. Twenty-one students were selected and divided into a control group and training group to gain comparable results. Results: A novel training method was developed in this study to promote the efficacy of safety stimulus by activating ABS of the subjects. Moreover, repeated trainings and preacquired relative knowledge can enhance this effect. Conclusion: This study develops an experimental approach to evaluate the effectiveness of safety education and safety training, and also provides a new research idea for accident prevention.

본 연구는 주의편향수정(Attention Bias Modification; ABM) 훈련에서 지시문(명시형, 암묵형)과 자극제시 시간(300 ms, 500 ms)에 따른 ABM 훈련의 효과를 대학생 사회불안 증상 집단을 대상으로 확인하고자 하였다. 부산 소재 대학의 대학생을 대상으로 사회적 회피 및 불편감 척도(Social Avoidance and Distress Scale; SADS)가 82점 이상이면서 주의편향 점수(Attention Bias Score; ABS)가 0보다 큰 참가자를 ABM 훈련 대상자로 선정하였다. 훈련 집단은 명시형-300 ms 집단(n=10), 명시형-500 ms 집단(n=8), 암묵형-300 ms 집단(n=8), 암묵형-500 ms 집단(n=7)이었다. 암묵형 지시문 집단에는 ABM 훈련 실시 절차 정보만을 제공하였다. 명시형 지시문 집단에는 추가로 훈련 조작(탐침이 항상 중성 자극이 나타났던 위치에 나타남)에 대한 정보를 제공하였다. 그리고 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 통제 집단은 통제-300 ms 집단(n=5), 통제-500 ms 집단(n=7)으로 구성하여 중성-중성 자극 쌍만을 제시하였다. 역시나 집단에 따라 300 ms 혹은 500 ms의 자극제시 시간을 사용하였다. 총 8회기의 ABM 훈련을 완료하고 SADS와 ABS를 재측정하였다. 분석 결과, ABM 훈련 효과는 지시문 집단에서만 나타났다. ABS 감소는 세 집단(명시형 지시문, 암묵형 지시문, 통제)에서 모두 유의하였지만, 명시형 지시문 집단의 처치 효과가 가장 효과적이었다. SADS 점수 감소는 명시형 지시문 집단에서만 유의하였다. 자극제시 시간에 따른 ABM 훈련 효과의 차이는 나타나지 않았다. 본 연구 결과는 명시형 지시문이 암묵형 지시문에 비해 ABM 훈련 효과를 증진시킬 가능성이 있음을 시사한다.

The present study used multi-faceted Rasch measurement to explore the characteristics and bias patterns of non-native raters when they scored L2 writing tasks. Three raters scored 254 writing tasks written by Korean university students on two topics adapted from the TOEFL Test of Written English (TWE). The written products were assessed using a five-category rating scale (Content, Organization, Language in Use, Grammar, and Mechanics). The raters only showed a difference in severity with regard to rating categories but not in task types. Overall, the raters scored Grammar most harshly and Organization most leniently. The results also indicated several bias patterns of ratings with regard to the rating categories and task types. In rater-task bias interactions, each rater showed recurring bias patterns in their rating between two writing tasks. Analysis of rater-category bias interaction showed that the three raters revealed biased patterns across all the rating categories though they were relatively consistent in their rating. The study has implications for the importance of rater training and task selection in L2 writing assessment.

The resilience of the exchange bias ($H_{EX}$) in ferromagnet / antiferromagnet bilayers is generally studied in terms of repeated hysteresis loop cycling or by protracted annealing under reversed field (training and long-term relaxation respectively). The stability of $H_{EX}$ is fundamental for practical application of exchange bias systems. In this paper we report measurements of training and relaxation in FeNi films coupled with the antiferromagnet FeMn. We show that $H_{EX}$ suppressed both by training and relaxation was partially recovered as soon as a field cycling for consecutive hysteresis loop measurement was stopped or the magnetization of the ferromagnet was switched back to the biased direction.

Purpose : The purpose of this study was to investigate the meta-analysis on the effects of action observation training on stroke patients' walking. Methods : Domestic databases (DBpia, KISS, NDSL, and RISS) were searched for studies that conducted randomized controlled trials (RCTs) associated with action observation training in adults after stroke. The search outcomes were items associated with the walking function. The 18 studies that were included in the study were analyzed using R meta-analysis. A random-effect model was used for the analysis of the effect size because of the significant heterogeneity among the studies. Sub-group and meta-regression analysis were also used. Egger's regression test was conducted to analyze the publishing bias. Cumulative meta-analysis and sensitivity analysis were also done to analyze a data error. Results : The mean effect size was 2.77. The sub-group analysis showed a statistical difference in the number of training sessions per week. No statistically significant difference was found in the meta-regression analysis. Publishing bias was found in the data, but the results of the trim-and-fill method showed that such bias did not affect the obtained data. Also, the cumulative meta-analysis and sensitivity analysis showed no data errors. Conclusion : The meta-analysis of the studies that conducted randomized clinical trials revealed that action observation training effectively improved walking of the chronic stroke patients.

The purpose of this study was to examine the effects of applying a program to enhance social information processing ability in schizophrenic patients. We confirmed the positive effects of the program on the theories of mind and attribution style, which are the social information elements of patients, and confirmed the effect of decreasing paranoid ideation. We used the theory of mind(hinting task, the false belief task), the attributional style questionnaire(external bias, personal bias), and the paranoia scale to test the effectiveness of the program. Specifically, in theory of mind, hinting task performance was improved(t=4.14, p=.000),. The scores of personal bias(t=-7.9, p=.000) and paranoid ideation(t=-2.98, p=.004) decreased. Further research is needed to verify the effectiveness of meta - cognitive training to enhance social information processing.

불확실한 환경과 다양한 이해관계자 속에서 살아남기 위해 조직은 창의성을 높일 수 있는 요인에 대해 지속적으로 탐색해왔다. 본 연구에서는 조직 창의성을 높일 수 있는 선행요인으로 정서적 몰입에 주목하고 이를 구체적으로 설명할 수 있는 인지적 상황요인을 탐색하였다. 즉, 정서적 몰입과 조직 창의성의 관계는 구성원들의 학습동기가 높을 때 더욱 명확해 질 것이라는 가설을 검정하기 위해 64개의 기업의 최고경영자와 472명의 종업원의 자료를 분석하였다. 연구결과, 조직구성원의 정서적 몰입은 조직 창의성에 영향을 미쳤으며, 정서적 몰입과 조직창의성의 관계는 학습동기가 높을수록 강화되었다. 이를 통해 조직구성원의 정서적 측면과 인지적 측면이 상호적으로 조화로울 때 조직창의성은 강화된다는 사실을 발견하였다. 본 연구는 최고경영자가 평가한 변수(조직 창의성)와 구성원들 스스로 평가한 변수(학습동기, 정서적 몰입)의 관계를 분석함으로써 변수들 간 동일방법오류(common method bias) 문제를 해결하고자 하였다. 향후 연구에서는 조직창의성을 유발하는 다양한 메커니즘을 탐색하려는 시도가 요구되며 이러한 메커니즘을 토대로 조직 내 관리자에게 보다 구체적인 가이드라인을 제시하려는 노력이 필요하다.

PURPOSE: This study was a systematic review and meta-analysis of the literature comparing the differences between task-oriented treadmill training and general treadmill training for stroke patients. METHODS: Literature published in the Cumulated Index to Nursing and Allied Health Literature (CINAHL), Embase, Physiotherapy Evidence Database (PEDro), and PubMed was reviewed. A total of 1,163 studies were initially retrieved, of which eight articles were included in the final review. A quality assessment of the included studies was conducted using the Risk of Bias (RoB) 2.0 tool, and Duval and Tweedie's trim and fill method was used to evaluate publication bias. Data analysis was performed using R studio 4.2.1. RESULTS: According to the quality assessment using RoB 2.0, three articles were evaluated as low risk, two as of some concern, and three as high risk. The overall effect size of task-oriented tradmill training was .35. Regarding gait function, the values were .76, .25, and .40, respectively, for gait endurance, gait speed, and gait pattern. According to Duval and Tweedie's trim and fill method, no publication bias was observed. CONCLUSION: Study findings indicate that task-oriented treadmill training is the most effective intervention for improving gait endurance in patients with stroke. Therefore, applying this intervention to patients with stroke in the community is recommended.
