본 연구는 부모애착, 또래관계 및 인터넷 과몰입이 청소년의 자아정체감에 미치는 영향을 알아보는데 목적이 있다. 연구대상은 중학생 206명, 인문계 고등학생 559명, 전문계 고등학생 92명, 총 857명의 청소년이다. 본 연구에서 사용한 부모애착 척도는 Armsden과 Greenberg(1987)의 부모 및 또래애착척도(The Inventory of Parent and Peer Attachment; IPPA) 개정본(IPPA-R)을 옥정(1998)이 번안한 것을 사용하였으며, 또래관계 척도는 김재은(2007)이 재구성한 또래관계 척도를 사용하였다. 자아정체감 척도는 송현욱(2008)이 재구성한 자아정체감 검사지를 사용하였으며, 인터넷 과몰입 측정도구는 김청택, 김동일, 박중규, 이수진(2002)이 개발한 한국형 인터넷 중독진단척도(K-척도)이다. 자료처리는 상관분석, 다중회귀분석을 적용하였다. 본 연구의 결론은 다음과 같다. 청소년의 부모애착은 자아정체감에 의미있는 영향을 주고, 또래관계 역시 자아정체감에 긍정적인 영향을 미친다. 그러나 인터넷 과몰입은 자아정체감에 부정적으로 영향을 미친다. 즉, 부모애착이 높고 또래관계가 긍정적일수록 자아정체감이 더 높으며, 인터넷 과몰입수준이 높을수록 자아정체감은 더 낮다. The purpose of this study is to validate the effect that the parent attachment, peer relationship and internet immersion would have on ego identity of adolescents. The subjects of this study are a total of 857 adolescents consisting of 206 middle school students, 559 adolescents of liberal arts high schools, and 92 adolescents of vocational high schools. The parent attachment scale used in this study is the revised version(IPPA-R) of the Inventory of Parent and Peer Attachment(IPPA) of Armsden and Greenberg(1987) which was translated by Ok Jeong(1998), while the peer relationship used in this study is the peer relationship scale reconstructed by Kim Jae-Eun(2007). For the ego identity scale, we used the ego identity test sheet reconstructed by Song Hyeon-Wook(2008). Moreover, the internet immersion measurement tool used in this study is the Korean Internet Addiction Proneness Scale(K-scale) developed by Kim Cheong-Taek, Kim Dong-Il, Park Jung-Gyu, and Lee Soo-Jin(2002). The collected data were processed for correlation analysis and multiple regression analysis. The results of this study are as follows: The parent attachment of adolescents had a significant influences on their ego identity while the peer relationship of adolescents also had a significant influence their ego identity. However, internet immersion had a negative influence on ego identity. In other words, ego identity increases higher when the extent of parent attachment is stronger and peer relationship is more positive. By contrast, ego identity decreases lower when the extent of internet immersion is higher.

This study aims to make suggestions to improve practically the current space usage on the basis of the results of investigating the spatial size and intended use of each building in the campus premises of Sahmyook university to understand objectively the current status of space usage, Such the current status was investigated using the official schedule of each lecture room, and all buildings were directly visited to compare their actual spatial size and intended use to their drawings, Based upon the results of this investigation, the following conclusions were drawn: A, For some departments (e.g., Chemistry, Food & Nutrition, Business Administration Information, Art Content, Communication Design, etc.) whose primarily used buildings are divided into twos, it is considered necessary to arrange their separate buildings into a single one in future. B. Even if any spaces other than primarily used buildings are to be used, it is required to place them close to primarily used buildings as possible. C. It seems to be required to give careful consideration to the Department of Social Welfare occupying the oldest and smallest building as well as the Departments of Health Management and Animal Biotechnology which have been newly separated without primarily used buildings. D. As professors` laboratories generally tend to be not located mainly in the primarily used buildings, but scattered on campus, it is thought that it is pressing to improve that in the aspect of student management and educational efficiency. E. Finally, it is considered that further studies should address whether administrative spaces other than department offices are centralized, and thus require rearrangement.

In the light that excavation works with conventional earth retaining techniques have negative influence upon nearby buildings or roads around the works, leading to several problems, a new earth retaining technique having better efficacy and constructability is increasingly demanded to minimize the known problems and negative influence. In this connection, this study was intended to suggest a new-concept construction method of permanent basement wall combined with earth retaining wall by using PHC piles to overcome the disadvantages of conventional CIP methods or the like which have been used just for earth retaining walls during field construction, and to determine its applicability.

PHC piles are characterized by the reliable quality attributed to prefabrication (shop fabrication) as well as superior concrete strength and steel-bar tensile strength to that of CIP in the aspect of materials, and also higher bending moment than that of CIP in the aspect of structure. Thus, this study was intended to apply PHC piles as a sort of permanent basement wall to a site where a soil investigation had been completed, to perform a structure analysis and to determine its applicability.

T형 모듈단면 합성 프로파일보의 거동에 관한 실험적 연구

안형준,이성원,류수현,Ahn, Hyung Joon,Lee, Seong Won,Ryu, Soo Hyun 한국강구조학회 2008 韓國鋼構造學會 論文集 Vol.20 No.4

본 연구는 기존에 발표한 T형 모듈단면 프로파일보의 적용가능성을 확인하기 위해 실험체를 제작하고 전단보강 유무에 따른 휨 및 전단거동을 측정하여 그 결과를 소성이론식과 비교 분석하였다. 모듈단면 프로파일보는 프로파일이 거푸집기능에 추가하여 휨 및 전단저항성능에 기여하고 모듈개념을 통해 성형성능을 향상시킨다. 실험결과 전단보강을 실시한 TS계열 실험체가 전단보강이 없는 T계열 실험체에 비해 우수한 휨저항 능력을 나타내 사용된 전단보강재는 적절하게 전단력을 분담하고 있는 것으로 파악되었으나 T1-1실험체를 제외한 모든 실험체에서 볼트의 전단파괴에 의한 모듈간 슬립현상이 발생되어 휨저항 성능이 충분히 발휘되지 못한 것으로 판단된다. 추후 전단연결재를 변수로 한 T형 모듈단면 프로파일보에 관한 연구를 통해 적절한 모듈간 접합방법이 연구 되어져야 할 것으로 판단된다. This study aims to determine the applicability of the previously published T-type modular profile beam in the manner of producing specimens designed specially for the said purpose, determining their bending and shear behaviors depending on the presence of shear reinforcement, and analyzing the results in comparison with the theoretical equation of plastic deformation. The modular profile beam contributes to bending and shear resistance with the addition of the profile to the form function, and enhances the molding performance through the modular concept. The experimental results showed that the TS series specimens with shear reinforcement have bending behaviors superior to those of the T series specimens without shear reinforcement, which suggests that the used shear reinforcement appropriately bears the shear force. However, it was considered that all the specimens except for the T1-1 specimen failed to have adequate bending performance because of the intermodular slipping caused by the shear failure of the bolts. It is expected that further studies on the T-type modular profile beam, in which shear connectors will be considered as a variable,be performed to develop optimal intermodular connection methods.

본 논문은 기존의 철근콘크리트의 단점을 개선한 Lip형 모듈단면 MSC보의 휨거동에 대하여 실험값과 이론값을 비교 분석하여 MSC보의 적용에 대한 기초적인자료를 제시하고자하였다. 기존의 SC보는 제작과정에서 절단 및 용접 등 많은 노동력을 필요로 하지만 MSC보는 박판강재를 측면모듈과 하부모듈의 2가지 형태로 모듈화 하여 필요한 크기의 SC보를 손쉽게 제작할 수 있는 프리패브의 개념을 도입하였다. 실험결과 모듈간의 결합방법 및 콘크리트와의 합성방법에 개선이 필요성이 나타났으며 추후 연구를 통해 모듈간의 결합력강화 및 강재와 콘크리트의 합성율을 높인다면 새로운 구조부재로 사용이 가능하다고 판단된다. In this paper, the basic data regarding the application of the MSC (Modular Steel Concrete) beam are presented by comparing the experimental value with the theoretical value, focusing on the bending behavior of the Lip-type MSC beam, which is composed of steel and concrete. Considerable manpower is needed to fabricate the traditional MSC beam, particularly for the tasks of cutting, welding, etc. Because much time is needed to fabricate the traditional SC beam, the prefabrication concept is introduced, easily produce the required size of the SC beam by prefabricating the side module and the lower module, which is made up of a steel sheet. The result indicates that the method of uniting the modules, an d the composition method with concrete, should be improved. The proposed MSC beam can be used as a new structural member by increasing its coherent reinforcement with modules and the composition ratio of steel and concrete through a future study.

This study aims to suggest an appropriate flexural reinforcement technique by evaluating the reinforcement capacity of specimens that underwent flexural reinforcement according to the post-tension method with the anchoring position of an unbonded tension member on the conventional SC composite beam and the applied tension level as variables. For the experiment, up to a predetermined yield load was applied to each type of specimen and then, unbounded post-tensioning was additionally conducted to examine its reinforcement capacity. The analysis of the said experiment showed that the post-reinforced SC composite beam was characterized by significantly improved yield stress and initial stiffness, compared with the pre-reinforced one and the experimental measurements/theoretical values of maximum stress ranged from 0.95 to 1.13 following reinforcement. There was little or no change depending on the maximum stress and tension in the specimen (D160, Class 240) whose neutral axis and upper part had anchoring devices mounted prior to reinforcement. Rather, the ductility decreased with the increasing tension. On the contrary, in the case of the other specimen (Class D120) whose neutral axis had anchoring devices mounted after reinforcement, both the maximum stress and ductility increased with increasing tension, which indicates that the latter tension reinforcement was reasonably appropriate and effective for the neutral axis reinforcement. 본 논문은 기존 SC합성보에 비부착 긴장재의 정착위치와 도입된 긴장량을 변수로하여 포스트텐션 공법으로 휨보강을 실시한 실험체의 보강성능을 평가하여 적절한 휨보강 방법을 제시하고자 하였다. 실험은 각 유형별 실험체를 항복하중까지 가력하고 항복 이후 비부착 포스트텐션 보강을 실시 추가 가력하여 보강성능을 조사하였다. 실험결과 보강된 SC합성보는 보강전에 비해 향상된 항복내력 및 초기강성을 나타냈으며 최대내력의 실험값/이론값은 보강 후 ${0.95{\sim}1.13}$으로 나타났다. 보강 전 중립축과 그 상부에 정착구를 설치한 실험체(D160, 240계열)는 최대내력에서 긴장력의 차이에 따른 변화는 거의 없고 오히려 긴장력이 증가하면 연성이 감소하였으며 보강 후 중립축에 졍착구를 설치한 실험체(D120계열)는 긴장력이 증가하면 최대내력이 증가하고 또한 연성도 증가하여 보강 후 중립축에 대한 적절한 긴장력 보강이 매우 유효함을 알 수 있었다.
