Eagle s syndrome is the term given to symptomatic elongation of the styloid process or mineralization of the stylohyoid or stylomandibular ligament. Although ossification of stylohyoid ligament was first described in the 1600 s, the syndrome is named for Eagle. Symptoms include the sensation of a foreign body, pain referred to the ear, dysphonia dysphagia, sore throat, require differential diagnosis such as unerupted thired molar, TMJ disorder, migraine, headache, atypical trigeminal neuralgia, otalgia, etc. Now, we present three cases of Eagle s syndrome treated by surgical resection of styloid process with good results.

Mild Cognitive Impairment(MCI) often represents a transitional stage betweeen normal aging and Alzheimer`s Disease(AD). Review of many studies of MCI and AD, The overall pattern of neuropsychiatric symptoms in MCI is similar to that seen in mild AD, with depression, apathy, agitation, anxiety, and irritability among the most commonly exhibited symptoms. Several longitudinal studies of MCI suggest that depression and apathy in particular may represent prodromal symptoms of AD that are indicative of subsequent development of dementia, althougth not all investigators have confirmed these findings. These symptoms have serious adverse consequences and should be inquired about and treated as necessary.

Sputter deposition followed by surface treatment was studied using reactive RF plasma as a method for preparing titanium oxide (TiO₂) films on the FTO (SnO₂: F) substrate for dye-sensitized solar cells (DSCs). Anatase structure TiO₂ films deposited by reactive RF magnetron sputtering under the conditions of Ar/O₂(5%) mixtures, RF power of 600W and substrate temperature of 400?C were surface-treated by inductive coupled plasma (ICP) with Ar/O₂ mixtures at substrate temperature of 400?C, and thus the films were applied to the DSCs. We have chosen a solar cell width as a variable of a large-scaled DSCs and confirmed electric characteristics of an individual cell. As a result, the higher the internal resistance of DSC becomes, the wider the width gets. Internal resistance makes it difficult to collect photoelectron generated from dye. Ultimately up sizing DSC causes the increase of internal resistance and then has a bad effect on the cell characteristics.

The purpose of this research is to identify the effect of quality circle activities upon quality circles performance and business performance. Empirical results indicate that quality circle activities influence on quality circles performance in both individual and enterprise level, Quality circles performance influences on not employment satisfaction but customer satisfaction. business performance (profitability and market values) of companies with quality circles is higher than that of companies without quality circles. In conclusion, quality circle activities influence on quality circles performance that effect on business performance.

Cost effectiveness is an important parameter for producing DSSCs as compared to the widely used conventional silicon based solar cells. A fluorine-doped tin oxide (FTO) substrate coated with a catalytic amount of platinum is used as counter electrode in dye-sensitized solar cell. Carbonaceous materials are quite attractive to replace platinum due to their high electronic conductivity, corrosion resistance towards I_{2}, good catalytic effect and low cost. In this paper, the unit DSSCs with Pt and CNT as a counter electrode were connected in series-parallel externally, then the current-voltage curves were investigated to find out the connection characteristics of the DSSC with CNT counter electrode. The connection characteristics of the DSSC with CNT counter electrode is superior to that of the DSSC with Pt counter electrode. And a parallel connection of the DSSC with CNT counter electrode has higher efficiency than a series connection of that.

We successfully treated a case of advanced abdominal pregnancy which was diagnosed with ultrasonography and magnetic resonance imaging in a woman of 20th week of pregnancy who did not receive any prenatal care. It is advisable to leave the placenta in situ because removing the placenta may be associated with severe hemorrhage. Furthermore, identifi cation of uterine wall around the fetus and the placenta is very important in diagnosing abdominal pregnancy.

복잡한 시스템을 구현하는데 컴포넌트의 사용이 유용하다는 것은 이미 누구나 인지하고 있는 사실이다. 엔터프라이즈 자바 빈즈(Enterprise JavaBeans, EJB)는 컴포넌트 트랜잭션 모니터를 위한 표준 서버측 컴포넌트 모델이다. 엔터프라이즈 자바 빈즈 아키텍쳐를 이용해 만들어진 어플리케이션은 확장서이 있고, 트랜잭션을 보장할 수 있으며, 다수 사용자 환경에서도 안전하다. 기존의 객체지향 방법론으로 어플리케이션을 개발하더라도 진정한 소프트웨어 재 사용성을 보장할 수 없었다. 그러나 EJB 아키텍쳐를 사용하면 소프트웨어 재 사용성을 보장하고 보다 용이하게 새로운 어플리케이션을 개발할 수 있다. 본 논문은 정확한 분석과 설계를 위하여, Rational rose의 UML을 이용하여 시스템을 모델링하고, 템플릿 제너레이트인 인라인(inline)과 비주얼 카페를 연동하여 온라인 주문 시스템을 구현하였다.

최근 컴퓨터 시스템 내부에 존재하는 웹 브라우저, 운영체제 커널 등에서 Use-After-Free 보안문제가 지속적으로 발생하고 있다. 해당 보안약점은 기존의 보안약점 탐지방법으로 제거하기 어려우며 소프트웨어 내부에 해당 보안약점이 존재할 경우 내부 보안에 심각한 영향을 미친다. 본 논문에서는 소프트웨어 개발 과정에서 해당 보안약점을 제거하기 위한 방안을 연구하였다. 이 과정에서 해당 보안약점의 발생 원인을 정리하고 이를 제거하기 위한 방법을 제시한다. Use-After-Free security problem is rapidly growing in popularity, especially for attacking web browser, operating system kernel, local software. This security weakness is difficult to detect by conventional methods. And if local system or software has this security weakness, it cause internal security problem. In this paper, we study ways to remove this security weakness in software development by summarize the cause of the Use-After-Free security weakness and suggest ways to remove them.
