Recently, semiconductor chips and electronic components are increasingly being used in IT devices such as wearable watches, autonomous vehicles, and smart phones. As a result, there is a growing concern about device malfunctions that may occur due to electromagnetic interference being entangled with each other. In particular, electromagnetic wave emissions from wearable or flexible smart devices have detrimental effects on human health. Therefore, flexible and transparent electromagnetic interference (EMI) shielding materials and films with high optical transmittance and outstanding shielding effectiveness have been gaining more attention. The EMI shielding films for flexible and transparent electronic devices must exhibit high shielding effectiveness, high optical transmittance, high flexibility, ultrathin and excellent durability. Meanwhile, in order to prepare this EMI shielding films, many materials have been developed, and results regarding excellent EMI shielding performance of a new materials such as carbon nano tube (CNT), graphene, Ag nano wire and MXene have recently been reported. Thus, in this paper, we review the latest research results to EMI shielding films for flexible and transparent device using the new materials.

Reinforcing bars are an important material for tensile strength of structures. For this reason, the inspection of the reinforcing bars confirming the layout and omission is very important for the safety of the structures. However, the current method of inspecting of the reinforcing bars through photographs of specific areas is difficult to identify condition all reinforcing bars. And It is also difficult to confirm after completion of a building. Therefore, reinforcing bar inspection using 3D scanner is required for automation of rebar inspection and database construction. For this purpose, this study test application of automated inspection method for rebar inspection using 3D scanner and discuss the effect of this method.

이 연구에서는 아동의 직접적인 실생활 관련인 부모가 개입한 중심반응중재가 자폐 스펙트럼 장애 유아의 사회적 의사소통 행동에 미치는 효과를 알아보았다. 자폐 스펙트럼 장애 유아 1명을 연구 대상으로 하여, 행동간 중다 간헐 기초선 설계를 적용하여 기초선, 중재, 유지 순으로 실험을 실시하였다. 부모 교육 후 주 3∼4회 가정 내에서 부모가 직접 중재를 실시하였으며 중재 후 어머니-유아간의 상호작용을 관찰하여 유아의 사회적 의사소통 행동(비언어적 의사소통 행동, 음성 모방행동, 자발적 시도 발화 행동)의 변화를 살펴보았다. 연구 결과, 부모 개입 중심반응중재를 통해 대상 유아의 비언어적 의사소통 행동, 음성 모방 행동, 자발적 시도발화 행동의 증가가 나타났다. 또한 중재 종료 후에도 중재의 효과가 유지 및 일반화 된 것으로 나타났다. 이러한 연구 결과를 통해, 부모 개입 중심반응중재는 자폐스펙트럼 장애 유아의 사회적 의사소통 행동 향상에 효과적이며 유지 및 일반화에도 효과적인 중재 방법임을 알 수 있었다. The purpose of this study was to examine effects of patent-mediated Pivotal Response Training (PRT) through parent education and feedback on social communicative behaviors (nonverbal communicative behaviors, vocal imitations, spontaneous utterance to requesting) of preschooler with autism spectrum disorders(ASD). For this study, one preschooler with ASD and his mother were selected and multiple probe design across behaviors has been used. Base line data were collected for social communicative behaviors during mother-young child interaction at home. After 6 sessions of parent education, mother implemented the PRT procedures to her young child during mother-young child interaction at home. During intervention sessions, evaluation was made for 10-minute observation session using partial-interval recording system and anecdotal record. The evaluation was made after the intervention. Follow-up data were collected 2 weeks after withdrawal of the intervention in the same setting as the baseline condition and the generalization was conducted by evaluating 3 session whether changes in untreated joint attention. The results of this study is as follows: parent-mediated PRT was effective to increase social communicative behaviors for preschooler with ASD and increased social communicative behaviors were maintained after withdrawal of the intervention and generalized changes in untreated joint attention. These results indicated that parent-mediated PRT is effective for increasing social communicative behaviors of preschooler with ASD and also for generalizing and maintaining.

To improve the formwork system in tall building construction, a systematic technique to solve various technical conflicts is required for its design process. Quality function deployment(QFD) has been applied as a systematic aid in determining the design in the construction area. However, it has limitation on deriving reasonable solutions through reflecting correlations between technical characteristics. TRIZ, which means an inventive problem-solving technique based on technical contradiction, can be an appropriate tool to resolve weak points of the QFD. Thus, this study proposes the improved design process for the formwork system in tall building construction through combining the QFD with the TRIZ. As a result, the proposed approach for formwork design showed improved performance on deriving high quality ideas and solutions reflecting mutuality of technical elements, compared to the QFD approach.
