본 연구는 예비유아교사의 학업적 자기효능감과 그릿이 행복감에 어떠한 영향력을 미치는지 확인하는 데 목적이 있다. 이를 위해 부산광역시, 울산광역시, 경상남도 내에 소재하고 있는 대학교의 유아교육과에 재학 중인 예비유아교사 300명을 임의표집하여 연구대상으로 선정하였다. 예비유아교사의 학업적 자기효능감을 측정하기 위해 김아영, 박인영(2001)이 개발하고 타당화한 후 김병만, 김정주, 윤정진(2017)이 수정하여 사용한 학업적 자기효능감 검사도구를 사용하였다. 고, 그릿을 측정하기 위해 Duckworth, Peterson, Matthews와 Kelly(2007)가 개발한 Original Grit Scale(Grit-O)를 이수란(2014)이 한국실정에 맞게 번안한 척도를 사용하였으며, 행복감을 측정하기 위해 Seligman(2011)의 웰빙에 대한 PERMA 이론을 토대로 Butler와 Kern(2014)이 개발하여 김미진(2015)이 번안한 다차원적행복척도(Multidimensional Measure of Flourishing: MMF)를 사용하였다. 본 연구의 결과는 다음과 같다. 첫째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감에 대한 인식에 대한 결과로 모든 변인에서 보통 이상의 긍정적인 인식 정도가 나타났다. 둘째, 예비유아교사의 학업적 자기효능감, 그릿, 행복감 간의 상관관계에는 유의미한 정적 상관관계가 있음을 알 수 있다. 셋째, 예비유아교사의 학업적 자기효능감은 예비유아교사의 행복감에 영향을 미치는 변인으로 나타났으나, 그릿은 예비유아교사의 행복감에 영향을 미치지 않는 변인으로 나타났다. The purpose of this study is to investigate the influence of pre-service early childhood teachers academic self-efficacy and grit on happiness. For this purpose, 300 Pre-service early childhood teachers in preschool education at universities located in Busan, Ulsan and Gyeongsangnam province were randomly sampled and selected. In order to measure the pre-service early childhood teachers academic self-efficacy, I used the academic self-efficacy test tool modified by Kim Byung-man, Kim Jung-ju and Youn Jung-jin (2017) after the development and validation of Kim Ae-Young and Park In-Young (2001). The original Grit Scale (Grit-O) developed by Duckworth, Peterson, Matthews and Kelly (2007) was used to measure grit. And to measure happiness, we used the multidimensional happiness scale developed by Butler and Kern (2014) and developed by Kim Mi-jin (2015) based on the PERMA theory of wellness in Seligman (2011). The results of this study are as follows. First, as a result of pre-service early childhood teachers perception of academic self-efficacy, grit, and happiness, positive perceptions were more than usual in all variables. Second, there is a significant positive correlation between the pre-service teacher s academic self-efficacy, grit, and happiness. Third, the academic self-efficacy of pre-service early childhood teachers was a factor affecting the happiness of pre-service early childhood teachers. Specifically, it was found that task difficulty preference, self-regulated efficacy, and self-confidence affect the happiness of pre-service early childhood teachers among the sub-variables of happiness. However, the sub-variables of Grit did not affect the pre-service teachers happiness.

1. Objectives : There are many studies on the ordinary symptoms based on Sasang constitution. But there are not quite satisfactory between the types of Sasang constitution. So This study is for learning the characteristics of ordinary symptoms depending on Taeyangin Soyangin(the rest Yangin) and Taeumin Soeumin(the rest Eumin) of the Sasang constitution. 2. Methods : We classified them into the each type of Sasang Constitutional Medicine(SCM) by the well-trained SCM specialist, and assessed their ordinary features by the questionnaire. Binary logistic regression analysis was applied to evaluate the influence of ordinary features to the diagnosis of SCM. 3. Results : There are a result of the binary logistic analysis on the observed questionnaire. 1) Regarding sleeping, Yangin do not dream much as Eumin do when they sleep. The time they are sleeping is not longer, and they usually do not sleep well. 2) Regarding stools, Yangin go to stool more than Eumin do. The constipation does not occur when they are not in a good condition, and they do not feel uncomfortable when they do not go to stool for a day. The length of time taken for emptying the bowels is much longer, and the hardness of their stools is much more, but the hardness does not mean that they have the constipation. 3) Regarding urine, Yangin have much more foam than Eumin. 4. Conclusions: We found that Yangin and Eumin have characteristics of ordinary symptoms, but partly there are not in accordance with ones what Lee Je-ma said in his book. So in future we hope clinical studies are required steadily.

Power cable tunnels is one of the underground structures meant for electricity transmission and are constructed using shield TBM method when transitting across urban and subsea regions. With the increasing shaft depth for tunnels excavation when the shield TBM excavated the rock mass, the review of selecting closed-type shield TBM in rocks becomes necessary. A simplified shield TBM design method is also necessary based on conventional geotechnical survey results. In this respect, design method and related design program are developed based on combined results of full-scale tests, considerable amount of accumulated TBM data, and numerical simulation results. In order to validate the program results, excavation data of a completed power cable tunnel project are utilized. Thrust force, torque, and power of shield TBM specification are validated using Kernel density concept which estimates the population data. The robustness of design expertise is established through this research which will help in stable provision of electricity supply.

70 MPa급 인공암반 내 실대형 쉴드TBM 굴진실험을 통한 굴진율 모델 및 활용방안 제안

김정주,김경열,류희환,정주환,홍성연,조선아,배두산,Kim, Jungjoo,Kim, Kyoungyul,Ryu, Heehwan,Hwan, Jung Ju,Hong, Sungyun,Jo, Seonah,Bae, Dusan 한국전력공사 2020 KEPCO Journal on electric power and energy Vol.6 No.3

전력송전을 위한 터널식 전력구는 점차 시공실적이 증가하고 있는 추세이며, 해저 및 대심도 등 시공환경이 어려운 구간의 건설도 증가하고 있다. 이에 소단면 쉴드TBM의 효율적 운영을 위해 굴진율 및 설계모델이 필요하다. 그러나, 제한된 지반조사 회수 및 굴착면 맵핑으로 인하여 암반특성과 굴진데이터를 정확히 매칭시켜 상호간 상관관계 및 굴진율 모델을 도출하는데 어려움이 있다. 이에 소단면 쉴드TBM에 적합한 굴진율 및 설계모델을 제시하기 위하여 커터헤드의 직경이 3.56 m인 실험용 EPB 쉴드TBM을 제작하고, 총 부피 87.5 ㎥인 인공암반 내에서 총 19번의 실대형 굴진실험을 수행하였다. 본 실험은 70MPa의 균질한 암반강도에서 수행되었기 때문에 운전변수인 추력과 커터헤드의 RPM에 따른 굴진율과 기계데이터간 상관관계를 효율적으로 분석할 수 있으며, 실제 굴착메커니즘과 동일하기 때문에 도출된 압입깊이와 토크값은 활용성이 높다. 본 연구를 통해 디스크커터 당 연직력과 압입깊이의 상관관계 및 연직력과 회전력의 상관관계를 도출하였다. 이러한 상관관계들을 이용하여 70 MPa급 암반에 대해 굴진율 예측과 TBM 설계가 가능할 것으로 판단한다. 또한, 인공암반의 RQD가 100%로 현장적용에 대한 한계점에 대해 FPI의 개념을 도입하여 굴진율 모델의 활용성을 증대시키고자 하였다. The use of cable tunnels for electric power transmission as well as their construction in difficult conditions such as in subsea terrains and large overburden areas has increased. So, in order to efficiently operate the small diameter shield TBM (Tunnel Boring Machine), the estimation of advance rate and development of a design model is necessary. However, due to limited scope of survey and face mapping, it is very difficult to match the rock mass characteristics and TBM operational data in order to achieve their mutual relationships and to develop an advance rate model. Also, the working mechanism of previously utilized linear cutting machine is slightly different than the real excavation mechanism owing to the penetration of a number of disc cutters taking place at the same time in the rock mass in conjunction with rotation of the cutterhead. So, in order to suggest the advance rate and machine design models for small diameter TBMs, an EPB (Earth Pressure Balance) shield TBM having 3.54 m diameter cutterhead was manufactured and 19 cases of full-scale tunneling tests were performed each in 87.5 ㎥ volume of artificial rock mass. The relationships between advance rate and machine data were effectively analyzed by performing the tests in homogeneous rock mass with 70 MPa uniaxial compressive strength according to the TBM operational parameters such as thrust force and RPM of cutterhead. The utilization of the recorded penetration depth and torque values in the development of models is more accurate and realistic since they were derived through real excavation mechanism. The relationships between normal force on single disc cutter and penetration depth as well as between normal force and rolling force were suggested in this study. The prediction of advance rate and design of TBM can be performed in rock mass having 70 MPa strength using these relationships. An effort was made to improve the application of the developed model by applying the FPI (Field Penetration Index) concept which can overcome the limitation of 100% RQD (Rock Quality Designation) in artificial rock mass.
