띄어쓰기는 한글 맞춤법에 명시되어 있는 규정에 따르면 되지만, 근본적으로 명확한 정의가 내려있지 않으며 복잡하고 애매모호한 기준들이 얽혀 사용자들이 혼란을 겪는 등 많은 오류를 일으키고 있다. 이에 맞춤법 오류에 대한 원인을 찾아 체계적인 교육이 이루어지거나, 맞춤법을 수정 및 보완할 필요성이 있다 하겠다. 본 연구는 사용자들의 편의성을 우선시하여 맞춤법에 있어 논리적 근거를 마련하고 한국어 정보처리의 양상을 살펴보는 것에 의의가 있다. 이에 비교적 띄어쓰기 기준이 명확한 관형어절에 초점을 두어 띄어쓰기가 읽기에 어떤 영향을 미치는지 알아보고자 실시하였다. '관형사 + 명사' 구조와 '~적 + 명사' 구조의 관형어절이 포함된 104개의 문장을 가지고 2개의 목록을 만들었다. 목록 간에는 띄어쓰기 여부가 반대이며 피험자는 목록 중 하나를 경험하였다. 하나의 문장을 끊어서 제시하여 피험자는 읽는 데로 space bar key를 누르는 자기 읽기 조절 과제를 시행하였고, 이어서 문장에 대한 질문을 통해 이해도 검사를 실시하였다. 관형어절을 읽는 평균 속도를 분석한 결과 미세한 차이가 있었으나, 유의미하지는 않았다. 이는 관형어절에 있어서 띄어쓰기의 영향이 크지 않음을 의미한다고 볼 수 있겠다.

Purpose: Root cause analysis (RCA) refers to any systematic process that identifies the causes that contribute to a focus event. The immediate cause of a focus event is often a symptom of underlying causes and may not truly identify the root causes that should be identified and addressed. Currently many RCA tools are available. Different investigators use different RCA tools on different issues. No standardized or commonly agreed way to analyse root causes exists. The purpose of this study is to propose the methodology of RCA process commonly useable for various issues. Methods: The methodology of RCA process is produced based on the hybrid RCA tools. The effectiveness assessment matrix of actions through the root cause candidates is presented. Results: No single RCA technique proposed has so far covered all necessary aspects. A hybrid approach which combines the best features of various techniques is proposed. The effectiveness assessment matrix helps us to identify the root cause to correct or eliminate system vulnerabilities effectively. Conclusion: This hybrid approach and effectiveness assessment matrix can provide guidance of RCA process across many industries and situations.

서비스 거부공격(DoS Attack : Denial-of-Service Attack)이란 공격자가 침입대상 시스템의 시스템 자원과 네트워크 자원을 대량으로 소모시킴으로써 정상 사용자로 하여금 시스템이 제공하는 서비스를 하지 못하도록 하는 공격을 의미한다. TCP SYN Flooding 기법을 이용한 DoS공격은 서비스 자체를 하지 못하도록 하기 보다는 다른 공격을 하기 위한 사전 공격으로써 활용될 소지가 높은 공격법인 것이다. 본 논문에서는 TCP SYN Flooding을 이용한 DoS공격의 근본적인 원인을 분석하고 시스템 보안 관리자의 입장에서 이 공격에 능동적으로 탐지 할 수 있는 해결책을 모색해보고자 한다.

The slope failures frequently occurred during heavy rainfalls in Korea of which 70% consists of mountains result in average 60 casualties and hundreds of millions US dollars of property damage. The status of design methods were analyzed with use of existing 102 design reports, Also, the design standards related to cut slopes are suggested by various institutions but the contents of standards are not proper to reflect the complicated geological features of Korea. And most reports rarely followed the suggested standards and are insufficiently conducted.

In the calendar and the advertising catalog, the surface Is usually coated by coating polypropylene film. The delamination failure of coating film depends on surface roughness and quality of the substrate paper. In this paper, the mechanisms of delamination failure between the coating film and the paper is investigated by using the root cause analysis as one of techniques of reliability evaluation. The papers used in failure analysis are three kind products made by two domestic and one foreign companies. It found that the main causes of delamination failure between the coating film and the paper were the creation of microvoids caused by shape of filler and their growth caused by contraction of paper.

The purpose of the current study was to research scientific basis and necessity of supplementary materials for field lesson out of golf swing teaching methods. As the subject of study, skillful tour pro golfers were chosen to reinterpret field lesson results for driver swing from the viewpoint of kinematics. In addition, through precise analysis, this study developed a case to verify the validity and error of field lesson. As a result, field lesson showed a slight difference among qualitative evaluation of kinematical analysis of techniques, subjects of study, and items. Accordingly, there was a little difference between two methods in view of evaluation of errors that 5 subjects of the study have shown. However, there was a significant difference in compensation to prevent causes of error and errors. Based on instructor's experience most errors could be evaluated. Therefore, feedback for error correction based on instructor's experience showed a significant difference from qualitative evaluation of kinematical analysis of techniques. In conclusion, the following are required for correct golf swing lesson; instant feedback through field lesson and qualitative evaluation of kinematical analysis of techniques to determine fundamental causes correctly.

The recent expansion in the number of housing construction projects has been accompanied by substantial improvements in construction quality, which can be attributed to the development of new construction technologies and materials. In apartment complex construction projects, numerous mechanization technologies have been adopted as part of the floor plastering process to counter increasing difficulties in securing labor and the pressing need to reduce lead time, but these have also triggered setbacks such as additional costs or loss of time to fix cracks in or loosening of floor. Cracks developing in the floor of an apartment housing unit, in terms of materials in use, are the products of a complex combination of material makeup, construction workmanship, concrete curing and the protection method. Controlling such elements from the perspective of materials in use may ensure partial success in reducing cracks, but fall short of eliminating them completely. Any attempt to prevent cracks from developing in the first place requires systematic analysis as to their potential causes and viable solutions to reduce them. On this backdrop, this paper aims to provide an analysis of potential causes of cracks found in floor plastering, and consider the mechanism of a crack stop-bar as a fundamental safeguard against them.

The target of this study is large scale rock slope collapsed by around 7 pm on August, 2012, which is located at ${\bigcirc}{\bigcirc}$ limestone quarries of Gangneung city, Gangwondo. The slope prior to the collapse is formed as the height of about 200 m and the average inclination of $45^{\circ}$. The estimated amount of the collapse is about $1,500,000m^3$ with respect to the slope after the collapse. Geotechnical and field investigations such as boring, geophysical prospecting, surface geological survey, geological lineaments, borehole imaging, metric 3D imaging, experimental and field test, mining work by year, and daily rainfall were performed to find the cause of rock slope failure. Various analyzes using slope mass rating, stereonet projection, limit equilibrium method, continuum and non-continuum model were conducted to check of the stability of the slope. It is expected that the cause of slope failure from the results of various analysis and survey is due to the combined factors such as topography, rainfall, rock type and quality, discontinuities, geo-structural characteristics as the limestone cavity and fault zones, but the failure of slope in case of the analysis without the limestone cavity is not occurred. Safe factor of 0.66 was obtained from continuum analysis of the slope considering the limestone cavity, so the ultimate causes of slope failure is considered to be due to the influence of limestone cavity developed along fault zone.

As the information technology is being rapidly developed, Korean government supplies various communication equipments to schools and therefore, it causes difficulties to cope with various faults from complicated school network communication equipments. These faults come from many reasons for wasting school budget and decreasing effectiveness in school administration. From this, it is necessary to figure out the problems of school communication equipments and cope with these problems quickly and preventing those faults in advance. In this paper, we present the school communication equipments analysis methodology not only quantitative but also qualitative aspects. We are sure that applying this methodology may improve the effectiveness of school network equipments management.
