The present study investigated the effects of video recording using a smartphone and self-evaluation of an English presentation on the improvement of the presentation. For about 10 weeks, 24 participants delivered two English presentations about common knowledge terms. The first English presentation was video-recorded using the smartphones of both the presenter and the professor. The video-recorded file was assessed by the professor and also self-evaluated by the presenter based on 30 items covering the presentation’s content, structure, delivery, and PowerPoint slides. The same procedure was also carried out for the second English presentation. To examine the improvement between the first and second presentations, the participants’ self-evaluation data were compared using a paired samples t-test. The results showed that the means of the second presentation data were significantly higher on all 30 items than the means from the first presentation. Additionally, the results of an independent samples t-test showed no significant difference between the professor's assessment and self-evaluation. According to surveys, most participants responded positively to smartphone video recording and self-assessment activity. These findings suggest that video recording of a presentation using a smartphone and a self-evaluation process for a presentation seem to be useful activitiesy to improve a presentation.

This study aimed to investigate the influence of feedback combinations on English writing performance and student perceptions in an online writing course conducted via Zoom during the COVID-19 pandemic. Sixty-eight college participants were divided into two groups: a control group of 33 students, who received only AI and teacher feedback during the writing process, and an experimental group of 35 students, who engaged in self-feedback before receiving AI and teacher feedback. To assess the effectiveness of the different types of feedback, students took TOEFL writing test respectively at the beginning and end of the semester. Additionally, to investigate learners’ perceptions towards different types of feedback, a post-questionnaire was administered to capture participants’ thoughts on them. The results revealed that the post-writing performance of both groups showed improvement from the pre-test scores. Notably, the group that received self-feedback demonstrated significant enhancement compared to the group without self-feedback. In addition, the group with self-feedback showed a positive perception towards self-feedback. Subsequently, students expressed their views on the advantages and disadvantages of each feedback. The study highlights the educational implications of using combined feedback methods.

LCD-TFT 라인이나 300mm 반도체 라인과 같은 전자제품의 생산라인은 inline type 설비로 구성된 job shop으로 간주할 수 있다. 본 연구에서는 uni-inline cell로만 구성된 LCD-TFT 라인을 parameterized event graph로 모델링 했다. 이는 Schruben(2001)에 제시된 general job shop 모델을 확장한 것이다. 이 연구에서는 물류 설비와 관련된 event는 나타나지 않으나 이 부분은 inline stocker와 컨베이어를 모델링함으로써 확장할 수 있다.

Background and objective: The purpose of this study is to investigate whether welfare horticultural therapists (hereinafterreferred to as "welfare HTs") have achieved self-growth through horticultural therapy experiences. Methods: The subjects of this study are 8 welfare HTs who have actively worked for more than 3 years after receiving awelfare HT license from the Korea Horticultural Therapy Welfare Association. As a research method, Colaizzi's phenomenologicalmethod was used. Through the study, a total of 123 semantic components, 34 themes, and 14 theme clusters werecollected under 5 categories. Results: The five categories are 'feeling dissatisfied with life', 'encountering horticultural therapy', 'being mesmerized byhorticultural therapy', 'difficulties in horticultural therapy', and 'experiencing self-growth through horticultural therapy'. Thefindings of this study are as follows. Welfare HTs have developed themselves through horticultural therapy experiences. They have had a desire to develop themself into a better existence since learning about horticultural therapy, and workingin the treatment field, using plants, through the recovery of clients and various difficult experiences, has consoled themand improved their emotional control and self-esteem. Conclusion: This study has the following significance. First, it focused on the specific context of working as a welfare HT. Second, it attempts an empirical study on self-growth through the experiences of welfare HTs, an important element inthe field of horticultural therapy, research of which has thus far been focused only on therapy programs . Third, it soughtto determine how welfare HTs achieve self-growth, so it seems that welfare HTs will be able to use these findings to learnabout and develop the abilities required to prepare themselves as mature experts.

Objectives : The publication of systematic reviews (SRs) has increased significantly over the years, and systematic reviews are considered to have the strongest evidence as they are at the top of the hierarchy of evidence pyramid. In this study, a thorough assessment of all SRs published in Journal of Society of Preventive Korean Medicine (JSPKM) was performed to evaluate their reporting quality and methodological quality to better improve the quality of SRs in JSPKM. Methods : JSPKM website was searched to include all SRs published in JSPKM from 1997 to 2018. Two independent researchers assessed the SRs using A MeaSurement Tool to Assess systematic Reviews (AMSTAR, formerly known as Assessment of Multiple Systematic Reviews) tool checklist for methodological quality assessment, and Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guideline checklist for reporting quality assessment. Results : Out of 618 published articles published in JSPKM from 1997 to 2018, only 3 SRs were identified as SRs. For AMSTAR methodological quality scoring, the average score of 3 SRs was 3.0 out of 11 which is low quality level. For PRISMA reporting quality items, the 3 SRs reported 17.3 items on average out of 27 items. The 3 identified SRs did not provide information on protocol or registration which is included in both AMSTAR assessment tool and PRISMA guideline. Conclusions : Improvements on reporting quality and methodological quality of SRs using relevant tools or guidelines are needed to assure the quality of SRs published in JSPKM so that their conclusions will be more transparent and reliable for decision-making in healthcare and the best clinical practice.
