In this study, a carbon fiber composite yarn with the desired stiffness and ductility was fabricated for use in hybrid grid fabrics for seismic reinforcement, and the optimum structures of the grid fabrics were evaluated. Carbon fiber composite yarn was prepared by a double-covering process with carbon fiber/aramid fiber/high-strength PET fiber. It was confirmed that the strength of the carbon fiber composite yarn was greatly increased compared to that of carbon fiber, and the elongation increased by about 0.5%. The TPU (thermoplastic polyurethane) extrusion coating method was more suitable for the carbon fiber composite yarn than urethane impregnation for the coating process. Meanwhile, in the evaluation of yarn fineness and grid structure, thick fibers had greater strengths. When comparing the strength and elongation, the bi-directional grid showed no advantages over the unidirectional grid.

In this study, a 6-line seaming method was used to connect woven geotextiles for soft ground reinforcement and select adhesives were added to the seaming part of the woven geotextile to improve the seam strength. Different reinforcement effects were observed according to the type of adhesive used. The strength retention of the seam strength was excellent when the cyanoacrylate adhesive was used in place of the epoxy adhesive. Since the reduction factor directly affects the tensile and seam strengths of the woven geotextile, it is essential to reinforce the seam using proper adhesives. The reduction factor and long-term performance of the adhesive agent are thought to contribute to the improvement of seam strength in woven geotextiles, and this was supported by the experimental results.

This study focuses on introducing the composition and operation cases of academic writing tutoring programs conducted for foreign graduate students of master's courses at a domestic university. This case consisted of two tutoring programs. Students in the master's degree program were from business administration, and professional tutors were selected from the Department of Korean Language Education with expertise and teaching experience. To examine the effectiveness of the tutoring programs, satisfaction surveys and in-depth interviews were conducted after tutoring sessions. The results of the study show that the tutoring programs help improve academic writing ability. Additionally, the regressive revision method implemented in the tutoring program helps the students realize their academic writing problems and prevent them from repeating the same mistakes. Moreover, the tutoring programs play a positive role in the structure, content, grammar and expression of their academic writing. This work offers meaningful insight into the effectiveness of academic writing tutoring programs and provides a direction of operation. .

본 연구에서는 주관적으로 결혼 불만족을 보고하는 부부를 대상으로 성 의사소통 훈련을 혼합한 부부대화법 집단 프로그램을 실시하고 그 효과를 검증하였다. 인터넷을 통해 두 차례에 걸쳐 모집한 부부들을 대상으로 첫 번째 모집한 부부들은 실험집단과 통제집단에 6쌍씩 무선할당 하였고, 두 번째 모집한 부부들은 각각 3쌍씩 무선할당 하였다. 연구 참여자들의 연령은 30세~48세의 범위를 보였다(M=37.43, SD=5.07). 실험집단 피험자를 대상으로 휴식시간 포함하여 150분씩 주 1회, 총 6회기의 프로그램을 실시한 반면, 통제집단에는 아무런 처치를 가하지 않았다. 프로그램의 효과를 알아보기 위해 한국형 결혼 만족도 검사(K-MSI), 의사소통 유형 척도 단축형(CPQ-SF), 성 만족도 척도를 사용하였다. 연구결과, 첫째, 결혼만족도의 경우 실험집단은 통제집단에 비하여 전반적 결혼 불만족, 정서적 의사소통 불만족, 문제해결 의사소통 불만족에서 유의미한 감소를 보였다. 또한 공유시간 갈등과 경제적 갈등에 대해서는 실험집단의 경우, 반복측정에 따라 통제집단 보다 크게 감소하는 유의미한 상호작용이 나타났다. 그리고 전반적 결혼 만족, 정서적 의사소통 불만족, 그리고 공유시간 갈등에 있어서 프로그램의 효과는 사후검사에서 나타나 6주 후 추후검사 때까지도 지속되는 것으로 나타났다. 그리고 문제해결 의사소통 불만족과 경제적 갈등의 경우는 프로그램 종료 후 추후검사에서 그 효과가 나타났다. 둘째, 의사소통 유형의 경우, 상호 요구/철회 의사소통 유형에 대해서는 실험집단의 경우, 반복측정에 따라 통제집단 보다 크게 감소하는 유의미한 상호작용이 나타났으며 그 효과는 프로그램 종료 후 6주 후 추후검사에서 나타났다. 결과에 대한 논의와 함께 연구의 의의와 제한점을 제시하였다. The purpose of this study was to investigate the effects of Minnesota Couple Communication Program-based Couple Communication Program in combination with Sexual Communication Training on the marital and sexual satisfaction for the distressed couples. The 18 couples for this study were recruited twice from the internet web sites that introduced and explained the couple communication program. The 18 couples were randomly assigned to the experimental and control groups. The control group received no treatment. The length of each session was 150 minutes. Pre-post test scales were Korean-Marital Satisfaction Inventory (K-MSI), The Communication Patterns Questionnaire-Short Form (CPQ-SF), and The Sexual Satisfaction Scale. The results were as follows: First, among the K-MSI sub-scales there were a statistically significant improvement of Global Distress, Affective Communication, Problem-Solving Communication, Time together, and Disagreement About Finances for the experimental group compared to the control group. This improvement lasted for the next six-week period after termination of the programs. Second, there was a statistically significant improvement for the alternate demanding /withdrawal communication pattern sub-scales of dysfunctional communication pattern of CPQ-SF for the experimental group compared to control group. Third, there was a statistically significant improvement of The Sexual Satisfaction for the experimental group compared to control group. This effects was maintained for following six weeks after the termination of this program. In conclusion, the study demonstrated that Couple Communication program in combination with Sexual Training Communication Program can be helpful for the marital satisfaction, and beneficial for distressed couples.

This study compared the differences in mental models of Autonomous Vehicles(AVs), which have recently received attention, by dividing them into ordinary people and occupational drivers. In Study 1, 16 psychological concepts(nodes) for car driving and AVs were extracted by interviewing ordinary people and occupational drivers. The connection relationship between the psychological concepts extracted for car driving in Study 2 and AVs in Study 3 was identified, and the differences in mental models between the two groups were compared. The relationship between concepts was analyzed through social network analysis. As a result of the study, there was a difference in the perceptions of car driving and AVs between ordinary people and occupational drivers. With respect to car driving, ordinary people recognized a direct relation with positive words such as relaxation, travel, family, and comfort, whereas occupational drivers recognized direct relation with occupations such as livelihood, accident, occupation, and labor. For AVs, ordinary people recognized a direct relation with only positive words such as freedom, leisure, and development, whereas professional drivers recognized not only positive words such as happiness, joy, and leisure but also nagative words such as anxiety, job loss, risk, crisis. This results show that ordinary people have more positive expectations for the changes that AVs will bring than occupational drivers. Whereas it can be said that occupational drivers have a more conservative attitude than ordinary people in accepting AVs, and show anxiety about job loss that AVs will bring. Based on the above results, the implications and limitations were discussed.

The purpose of this study was to identify whether shoulder complex exercise program with visual feedback could improve the shoulder muscular strength and postural alignment in adolescents with shoulder asymmetry. Twenty eight subjects were recruited from the K university and divided into three groups: experimental 1, 2group(Each n=10) and control group(n=8). For 4 weeks, the experimental group 1 performed shoulder muscle complex exercise program and the experimental group 2 performed shoulder complex exercise program with visual feedback. The control group did not perform exercises. The shoulder muscle strength and difference between the height of left and right shoulders were assessed before, after training using the hand-held dynamometer and Global Posture System. Subordination variables, general characteristics analysis, χ² test and Kruskal Wallis H test were conducted to evaluate differences between groups and training before, after changes were checked Wilcoxon signed rank test with using the PASW 18.0 statistical program. The results of the study were as follows. 1) Both the experimental 1, 2group showed improvements in muscle strength of several muscles following training (p<.01). The control group showed significant reduction in the left posterior deltoid (p<.05), and did not show significant changes in examining other muscles (p>.05). And there were differences among three groups in shoulder muscle strength (p<.001). Muscle strength changes in several muscles were greater in the experimental 1, 2group compared with the control group (p<.001). Muscle strength changes in the several muscles were greater in the experimental group 2 compared with the experimental group 1 (p<.001) 2) Both the experimental 1, 2group showed significant decreases in the difference between the left and right shoulder heights following training (p<.01). The control group did not show change (p>.05). Changes in the difference between the left and right shoulder heights were greater in the experimental 1, 2group compared with the control group (p<.001).

다문화 자녀를 위한 한국어(KSL) 교원 재교육 프로그램의 방향 탐색 -한국어(KSL) 교원 대상 설문조사를 중심으로-

김은호(Eunho Kim),연우진(Yuzhen Yan) 중앙대학교 문화콘텐츠기술연구원 2020 다문화콘텐츠연구 Vol.0 No.35

본 연구는 2019년에 시행되었던 국립국어원 한국어교원 재교육 프로그램인 ‘한국어(KSL) 교원 배움이음터’ 참가자의 만족도 및 요구분석을 실시하여 그 결과를 토대로 후속 연수 프로그램을 위한 개선 방안과 방향성을 제안하였다. 사전 과제로 제시되었던 국립국어원 한국어교수학습샘터 온라인 연수의 수강에 대해서는 대부분의 참여 교원들이 긍정적인 반응을 나타냈다. 그러나 교육 내용의 실제성 증진이 필요하다는 점과 함께 현재 제시되어 있는 영역별 주제가 한정적이라는 의견을 반영하여, 교육 내용의 다양성 확보와 함께 교사들이 실제 현장에서 겪는 어려움과 관련된 내용을 중심으로 한 강의를 개발·제공할 것을 제안한다. 강의는 재교육 프로그램에서 가장 높은 비중을 차지하는 부분으로, 이론적 내용 전달 중심으로 진행되었던 강의의 만족도는 비교적 낮았다는 점을 고려할 때, 일방향적인 형식보다는 실습형 혹은 토의형으로 강의를 구성할 필요가 있다. 한국어(KSL) 교원들이 추후 희망하는 연수회의 강의 주제는 ‘교육 자료’에 대한 의견이 주를 이루었다. 특히 한국어 교육 관련 지식과 경험을 이미 지니고 있는 교원들이 현장에서 활용할 수 있는 내용을 다룰 수 있는 주제 선정과 강의 구안이 필요하다. 2019년 한국어(KSL) 교원 배움이음터에 참가한 교원들이 앞으로의 연수에서 다루기를 원하는 분임토의 주제로는 ‘교육 자료’ 또는 ‘교실 활동 구성’이 있었다. 참여 교원들의 유의미한 분임활동을 지원하기 위하여 분임별로 의견을 충분히 교환하고 서로의 경험을 공유할 수 있는 장을 제공할 수 있는 형태로 연수회 프로그램을 구성해야 할 것이다. This study aims at investigating whether the new Korean Language Teacher Training program(baeum-ieum-teo) for Korean as second language(KSL), by National Institute of Korean Language which was put into practice in 2019 promotes prospective Korean language teachers awareness of Korean language. In doing so, 50 current KSL Program teachers participated in the study. The data was collected through a questionnaire. As a result, most of the participating teachers responded positively to the online training at the National Institute of the Korean Language, which was presented as a preliminary task. However, there were opinions on limited topics and lack of practicality in the existing educational content. Accordingly, it is proposed to secure diversity in educational content and develop and provide lectures centering on contents related to difficulties that teachers experience in the field. In terms of lectures, it is necessary to organize lectures in a practical or discussion type rather than a one-way lecture. The subject of lectures KSL Korean teachers hoped for in the future was mainly ‘educational materials’. In particular, it is necessary to select topics and design lectures that can deal with contents that can be used by teachers who already have knowledge and experience related to Korean language education. Also, in order to support teachers effective data production activities, it is necessary to provide a place for teachers to exchange opinions by division, and propose a program structure that allows them to be actively used in the pre-, mid-, and post-departmental discussions.

PURPOSES : The purpose of this study is to investigate the optimal joint positions which can minimize distresses of concrete pavement containing box culvert with horizontally skewed angles. METHODS : The concrete pavement containing the box culvert with different skewed angles and soil cover depths was modeled by 3dimensional finite element method. The contact boundary condition was used between concrete and soil structures in addition to the nonlinear material property of soil in the finite element model. A dynamic analysis was performed by applying the self weight of pavement, negative temperature gradient of slab, and moving vehicle load simultaneously. RESULTS: In case of zero skewed angle (0。), the maximum tensile stress of slab was the lowest when the joint was positioned directly over side of box culvert. In case there was a skewed angle, the maximum tensile stress of slab was the lowest when the joint passed the intersection between side of the box culvert and longitudinal centerline of slab. The magnitude of the maximum tensile stress converged to a constant value regardless the joint position from 3m of soil cover depth at all of the horizontally skewed angles. CONCLUSIONS: More reasonable and accurate design of the concrete pavement containing the box culvert can be possible based on the research results.
