The Evaluation Methods of the Maxillary Sinus for Ensuring Predictability in the Sinus Graft Surgery
Jang-yeol Lee, Hyoun-chull Kim, Il-hae Park, Sang-chull Lee 대한치과이식임플란트학회 Journal of Dental Implant Research 13 Pages
대한치과이식임플란트학회 Journal of Dental Implant Research 2007, 제 26권 2호 7 61-73 (13 pages)
The edentulous posterior maxillary region presents unique and challenging conditions in implant dentistry compared with other regions of the jaws1,2). The available bone is lost from the inferior expansion of the sinus and residual ridge resorption after tooth loss. These factors increase stress to the implants. However, despite these concerns, treatment methods designed specifically for this area allow it to be as predictable as any other intraoral region. -
기초간호자연과학회지 게재논문 분석을 통한 기초간호 연구동향

과학의 기본 목표는 수용가능한 이론을 제시하는 것으로(Fraassen, 1986), 과학의 발전은 검증을 거친 이론을 실제에 적용하는 응용과정을 통해 지식체를 확대시킴으로써 가능해진다. 자연과학의 한 분야인 간호학에서도 간호 지식체를 개발하고 확대시키기 위해 이론 또는 실무중심의 다양한 간호연구가 이루어지고 있다. 간호연구는 간호에서 관심 있는 개념과 문제들을 다양한 방법론을 활용하여 체계적으로 탐구하는 과정으로(Hinshaw, 1989), 간호지식체를 발전시키고 확대시킬 수 있는 최선의 방법이다. 더 나아가 간호학의 발전과... -
Effect of the surface modification using MWCNTs with different L/D by two different methods of deposition on the IFSS of single carbon fiber-epoxy resin composite

Multiwall carbon nanotubes (MWCNT) with two different (L/D) aspect ratios (7±2 μm/140±30 nm and 0.5?2 μm/8?15 nm) were surface treated using nitric acid (HNO3) and polyethyleneimine (PEI) prior to their deposition on carbon fibers (CF). Before the hierarchical reinforcement with CF-MWCNT, the CFs were treated with 3-glycidoxypropyltrimethoxysilane, a coupling agent (Z6040) and with poly(amidoamine) (PAMAM) a dendrimer containing an ethylenediamine core and amine surface groups. The MWCNT... -
NO gas sensing ability of activated carbon fibers modified by an electron beam for improvement in the surface functional group

Activated carbon fiber (ACF) surfaces are modified using an electron beam under different aqueous solutions to improve the NO gas sensitivity of a gas sensor based on ACFs. The oxygen functional group on the ACF surface is changed, resulting in an increase of the number of non-carbonyl (-C-O-C-) groups from 32.5% for pristine ACFs to 39.53% and 41.75% for ACFs treated with hydrogen peroxide and potassium hydroxide solutions, respectively. We discover that the NO gas sensitivity of the gas sensor... -
Effects of cross-linking methods for polyethylene-based carbon fibers: review

and the use of CFRP has been impeded by the high cost of CF in various applications. This paper presents an overview of research related to the fabrication of low cost CF using polyethylene (PE) control technology, and identifies areas requiring additional research and development. It critically reviews the results of cross-linked PE control technology studies, and the development of promising control technologies, including acid, peroxide, radiation and silane cross-linking methods. -

In this study, carbonized fibers were prepared by using acidically cross-linked LDPE fibers. The surface morphologies of the carbonized fibers were observed by SEM. The effects of cross-linking process temperatures were studied using thermal analyses such as DSC and TGA. The melting and heating enthalpy of the fibers decreased as the cross-linking temperature increased. The cross-linked fibers had a carbonization yield of over 50%. From SEM results the highest yield of carbonized LDPE-based... -
An overview of new oxidation methods for polyacrylonitrile?based carbon fibers
Hye Kyoung Shin, Mira Park, Hak-Yong Kim and Soo-Jin Park 한국탄소학회 Carbon Letters 8 Pages
한국탄소학회 Carbon Letters 2015, Vol.16 No.1 2 11-18 (8 pages)
The process of oxidizing polyacrylonitrile (PAN)-based carbon fibers converts them into an infusible and non-flammable state prior to carbonization. This represents one of the most important stages in determining the mechanical properties of the final carbon fibers, but the most commonly used methods, such as thermal treatment (200°C to 300°C), tend to waste a great deal of process time, money, and energy. There is therefore a need to develop more advanced oxidation methods for PAN precursor...
