Objectives The purposes of this study is to examine the mediating effects of sosial support between uncertainty adult attachment and resilience of university students. Methods A total 389 students who randomly sampled responsed to the questionnaire at university in Gyeonggi-do. The study utilized Experience in Close Relationship-Revised(ECR-R), Social Support and Resilience questionnaire. For the collected data was used by the SPSS 24.0 program and reliability analysis, frequency analysis, descriptive statistics analysis, and correlation analysis were performed. Baron and Kenny's mediation analysis was conducted to verify the mediating effect of social support between uncertainty adult attachment and resilience. Results As a result of the correlation analysis of each variable, Both attachment anxiety and attachment avoidance showed a statistically significant negative correlation with resilience, and both attachment anxiety and attachment avoidance showed a statistically significant negative correlation with social support. In addition, social support was found to have a statistically positive correlation with resilience. Social support was found to play a partial mediating role in the relationship between insecure adult attachment and resilience. Conclusions Through this study, it was found that social support has a positive effect on resilience. And In order to improve resilience, the importance of the surrounding roles of family, friends, schools, and neighbors was found. In addition, even if there are no support resources in the family, the warm interest and heart of social members toward teenagers should come first.

원자력발전소 증기발생기 전열관 보수 기술의 하나로 니켈 합금 전기 도금이 연구되고 있다. 여러 도금 공정변수 중 peak current density를 달리하여 Ni-P-Fe 전기도금층을 제조한 뒤, 열처리 온도 325℃에서 10, 30일간 열처리를 한 후, 인장강도와 연신율을 측정하고, 그 파단면을 관찰하였다. 50㎃/㎠로 제조된 도금층은 100㎃/㎠로 제조된 도금층에 비해 우수한 열적안정성을 가짐을 알 수 있었다

Purpose: Periodontal intrabony defects have great deal of importance since they contribute to the development of periodontal disease. Current treatment regimens for intrabony defects involve grafting of numerous bony materials, GTR using biocompatible barriers, and biomodification of root surface that will encourage the attachment of connective tissue. Xenograft using deproteinized bovine bone particles seems to be very convenient to adjust because it doesn't require any donor sites or imply the danger of cross infections. These particles are similar to human cancellous bone in structure and turned out to be effective in bone regeneration in vivo. We here represent the effectiveness of grafting deproteinized bovine bone particles in intrabony defect and furcation involvements that have various numbers of bony walls. Materials and methods: Open flap debridement was done to remove all root accretions and granulation tissue from the defects within persisting intrabony lesions demonstrating attachment loss of over 6mm even 3 months after nonsurgical periodontal therapy have been completed. Deproteinized bovine bone particles($BBP^{(R)}$, Oscotec, Seoul) was grafted in intrabony defects to encourage bone regeneration. Patients were instructed of mouthrinses with chlorohexidine-digluconate twice a day and to take antibiotics 2-3 times a day for 2 weeks. They were check-up regularly for oral hygiene performance and further development of disease. Probing depth, level of attachment and mobility were measured at baseline and 6 months after the surgery. The radiographic evidence of bone regenerations were also monitored at least for 6 months. Conclusion: In most cases, radio-opacities increased after 6 months. 2- and 3-wall defects showed greater improvements in pocket depth reduction when compared to 1-wall defects. Class I & II furcation involvements in mandibular molars demonstrated the similar results with acceptable pocket depth both horizontally and vertically comparable to other intrabony defects. Exact amount of bone gain could not be measured as the re-entry procedure has not been available. With in the limited data based on our clinical parameter to measure pocket depth reduction following $BBP^{(R)}$ grafts, it was comparable to the results observed following other regeneration techniques such as GTR.

This paper presents a method to minimize the initial deflection of a multi-layer piezoelectric microactuator without loosing its piezoelectric deflection performance required for light modulating micromirror devices. The multi-layer piezoelectric actuator composed of PZT silicon nitride and platinum layers deflects or buckles due to the gradient of residual stress. Based on the structural analysis results and relationship between process conditions and mechanical properties we have modified the fabrication process and the thickness of thin film layers to reduce the initial residual stress deflection without decreasing its piezoelectric deflection performance. The modified designs fabricated by surface-micromachining process achieved the 77% reduction of the initial deflection compared with that of the conventional method based on the measured micromechanical material properties is applicable to the design refinement of multi-layer MEMS devices and micromechanical structures.

본 논문에서는 국내의 대국민 경보 서비스를 파악하고 재난이 발생했을 경우 재난문자가 이동통신 기기인 스마트 폰에서만 수신된다는 문제점을 인지하였고 근거리 무선통신을 이용해 내비게이션에서도 재난문자를 확인할 수 있는 방 안에 대해 연구를 진행하였다. 애플리케이션 개발이 가능한 내비게이션뿐만 아니라 스마트 폰 내비게이션을 사용할 때도 재난문자와 재난 정보를 수신해서 활용하는 방안에 대해 연구를 진행하였다. 해당 논문과 같은 연구가 계속된다면 재난 상황과 정보를 보다 다양한 환경에서 제공 받고 사용자 모두 재난 콘텐츠에 접속해서 재난에 대비하고 재난에 대한 피해 를 예방하거나 감소시킬 수 있을 것이다. In this paper, we identified the national alert service and recognized the problem that disaster message is received only from smart phones, which are mobile communication devices in the event of a disaster. Thus, we conducted a study on how to use NFC to identify disaster characters in navigation. Research was conducted on how to receive and utilize disaster message and disaster information when using smart phone navigation as well as application development-enabled navigation. If studies such as those in question continue, disaster situations and information will be provided in a more diverse environment and users will all be able to access disaster content to prepare for disasters and prevent or reduce damage.
