  • Background and Objective The purpose of this study is to report the effect of voice therapy using the voice reinforcement method (VRM) in patients with vocal nodules. It is one of the holistic voice therapy methods for improving vocal mechanisms. VRM includes not only direct and indirect voice therapy, but also trial therapy and self-practice. Composed of four stages: vocal hygiene education, relaxation, reinforcement, and generalization. Materials and Methods The subjects were 13 patients who were diagnosed with vocal nodules. Acoustic analysis, auditory perceptual assessment, K-VHI-10 and nodules size were compared before and after voice therapy. Voice therapy was conducted by speech-language pathologist and the mean number was 4.2. Results In acoustic analysis, Jitter, vF0, vAm, Shimmer, NHR, and VTI were significantly decreased. F0 was increased after voice therapy for women. 'Grade', 'Rough,' and 'Breathy' were significantly decreased in the GRBAS scale after voice therapy. In addition, K-VHI-10 and nodules size were significantly decreased. Conclusion VRM seems to be an effective voice therapy method in vocal nodules treatment. In VRM, especially, trial therapy is given motivation for vocal nodules treatments and self-practice has a continuous therapeutic effect in everyday life. VRM can be also applied to the voice therapy for other hyper-functional dysphonia.

  • This research examines the impact of teachers' self-evaluation on their classroom interactions with students. Changes in class behavior were analyzed by following two experienced middle school teachers for one semester of self-evaluation, comparing their classes at the beginning and end of the semester. A qualitative research method was adopted to take, a deeper look at the effect of changes in the teachers' in class actions. Both of the teachers reported positive effects of implementing self-evaluation on their teaching pedagogy, focusing specifically on their interactions with students when asking question and giving feedback. By the end of semester, they were asking broader questions that encouraged their students to engage in deeper thought and, when giving feedback, the class atmosphere was much brighter with better communication due to the positive reinforcement provided. This research supports research into ways to enhance teachers' expertise and improve their teaching via self-evaluation, centering on teachers' actions in the classroom.

  • Locus of Control of Reinforcement (LOCR)' is considered as one of the most important factors on responsible environmental behaviors(REB). It is defined as 'an individual's perception of his or her ability to bring about change through his or her behavior'. This psychological construct is divided up into two directions: the external locus and internal locus. The internal locus is important as a predictor of REB. Recently, 'The Environmental Action Internal Control Index: EAICI' has been developed and it is a valid and reliable instrument to measure the relationship of two variables. The purposes of this study were to develop a strategy to reinforce the internal locus or to converse external locus to internal locus. and to verify the effects by EAICI. A new strategy, 'Self Control Management Strategy' was based on the characteristics of internal locus and the key idea of this was to self-control and to manage the courses by themselves. EAICI scores of the control group was 99.83. All of them were internal and the LOCR of females was more internal than that of the males. This strategy was applied when the instructions were carried out on seven environmental issues by the experimental group. According to the results. the seven points of the EAICI were increased significantly. Therefore this strategy is helpful in reinforcing the internal locus or to converse external locus to the internal locus.

  • Ultra high performance concrete (UHPC) can be used in the UHPC-steel composite structures especially for bridge structures to achieve high stiffness and high fatigue resistance with low self-weight. The structural performances of UHPC-steel composite slabs subjected to hogging moment have a significant influence on the global stiffness and durability of UHPC-steel composite structures. In order to study the structural behaviors of non-steam-cured UHPC-steel composite slabs subjected to negative moment, five composite slabs combined the thin UHPC layers to steel plates via shear stud connecters with the diameter of 16mm were fabricated and tested under negative moment. The test program aimed to investigate the effect of stud spacing and longitudinal reinforcement ratios on the failure mode, load-deflection behaviors, cracking patterns, bond-slips, and carrying capacities of composite slabs subjected to negative moment. In addition, direct tensile tests for the dog-bone UHPC specimens with longitudinal reinforcement bars were carried out to study the effect of reinforcement bars on the tensile strength of UHPC in the thin structure members. Based on the experimental results, analytical models were also developed to predict the cracking load and ultimate load of UHPC-steel composite slabs subjected to negative moment.

  • It requires to make the safety education not a merely formal education but as a practical one for the factor of safety on the industrial environment. We surveyed the workers who are working for a power plant-related small and medium sized businesses around Incheon about the necessity of safety education to improve the safety awareness for themselves. The answered workers for the survey are numbered 198, and we can analyzed those questionnaires by using SEM(Structural Equation Modeling). We ran the analysis by the tool of statistics, AMOS19.0. We examined the basic hypothesis that self-efficacy, safety education, and perceived safety influenced on the will for the safety on the job through the attitude of safety on the work as a parametric cause. We can derive a result that self-efficacy and education about safety makes an effect not only on the will for the safety directly, but also through the attitude and perceived safety. Perceived safety does not influenced on the attitude of safety on the work. Education, attitude, and perceived safety show positive influential factors, but self-efficacy represents negative effect directly on the will for the safety. Safety eduction makes more positive effect on the attitude and perception of the safety, and it shows the necessity for the reinforcement.

  • Recently, it is required to develop a monitoring technology that combines an FBG sensor as a means for continuously monitoring whether reinforcing effect of FRP is maintained on FRP reinforced structural members. However, most existing researches focus on the insertion of FBG sensors into bar-shaped FRPs, and there is insufficient study on the details strip-type FRPs combined with FBG sensors. Therefore, in this paper, it is studied to develop a reinforcement in which a FBG sensor is combined with a FRP strip. Especially, combination of FRP and FBG sensor. For this, a series of experiments were performed to find the adhesive strength of fiber-FRP-epoxy joints, the tensile strength of FBG sensor part with reflection-lattice, and the performance depending on the connection method of FRF and FBG sensor. As a result of the study, it was found that a minimum strength of $216.15N/mm^2$ is required for incorporating FBG sensors in FRP using epoxy. It is considered that the adhesion length of epoxy joints should be more than 50mm. When the FBG sensor is attached to the FRP strip as an epoxy, it is considered appropriate to use the complete attachment and the sensor non-attachment method.

  • RC 플랫 플레이트 시스템은 공기단축, 시공성 향상, 층고 절감 등의 장점이 있으나, 장스팬 적용 시 슬래브의 작은 휨강성으로 인해 균열 손상 및 과다 처짐이 발생하는 경향이 있다. 특히, 시공 중 슬래브 자중에 의한 과하중의 작용이 슬래브의 장단기 처짐을 증가시킬 수 있다. 이러한 문제점은 자중 저감이라는 장점을 갖고 있는 중공 슬래의 사용을 통해 해결할 수 있다. 이 연구에서는 슬래브 처짐에 대한 중공 슬래브의 자중저감 효과를 분석하기 위하여 변수연구를 수행한다. 콘크리트 강도, 슬래브 시공주기, 동바리 지지층수, 압축철근비, 인장철근비 등의 변수조건들을 포함하여, 시공단계, 콘크리트 균열, 장기 효과를 고려한 시공하중 및 처짐을 산정한다. 일반 슬래브와 중공 슬래브에 대한 시공 중 단기처짐과 완공 후 장기처짐을 비교하고, 슬래브 처짐에 대한 중공 슬래브의 효과를 분석한다.
