사고예측모형은 도로에서 발생한 교통사고자료를 통계적으로 모형화한 것으로 종속변수는 과거의 사고건수가 되고 설명 변수로는 주로 사고가 일어난 장소의 도로 기하구조 조건, 교통조건, 운영조건 등 도료의 속성자료가 이용된다. 기존의 사고예측모형의 한계를 극복하고자 새로운 방안인 Hauer의 연구를 구체적으로 소개하고 이를 국내 고속도로 사망사고자료를 통해 적용하였다. Hauer의 방법론에 의한 사고예측모형을 구축한 결과 AADT와 종단구배를 통해 사고예측모형의 적합도를 상당히 높일 수 있었으나, 곡선반경은 사고건수와 직접적 인 관련이 있는 것으로 파악되지 않았다. 이러한 사고예측모형은 기존의 모형과 비교 시 여러 설명변수 중 어떤 변수가 모형에 도입되어야 하는지를 결정할 때 분명한 근거를 지니기 때문에 중요한 변수가 누락되거나 혹은 중요하지 않는 변수가 도입될 가능성 이 낮아지는 장점을 지니고 있다.

The causes of juvenile crimes are varying with many reasons, can not be just defined with one reason. It is very easy for juveniles to become violent and fall into misdeed, bad social environment; such as, family or parents' divorce problems accelerates this kind of misbehavior, especially when they are mentally acuity in this stage of their lives. On the impulse of the moment directly connects to the delinquencies which make their life miserable and furthermore, they become an obstruction of the society and country. Juvenile delinquents have to be take cared with psychological treatments, such as using a dog, because their hearts are dried up for many reasons. It is possible to help delinquents in The Chun An Juvenile Prison to reduce criminal minds and violent behaviors through psychological treatments and reform edification to make them love animals. This study has been researched through result of surveysand MMPI tests on guard diaries and observation record for using dogs as a treatment for violent reduce of juvenile delinquents in The Chun An Juvenile Prison. With the result, we came to the conclusion that it will be a suitable program for juvenile and female delinquents in the future.

20세기 말 미국 법원의 친 특허적 성향을 바탕으로 성장한 Patent Troll이 20세기 초반의 닷컴 산업 붕괴와 함께 급속히 확산되자 이에 대한 비판론이 팽배하는 동시에 그 긍정적 기능을 강조하는 옹호론자들의 목소리도 커지고 있다. 최근의 사례들을 살펴 보면, Patent Troll이라 지칭되던 개인이나 조직들이 목표기업을 공략하는 데에 있어 다양한 전략을 구사하는 전문적인 기업으로 발전해 가고 있음을 알 수 있다. 또한, 일반 대기업들도 Troll 행위에 대한 단순한 방어를 하는 데에 그치지 않고 이윤창출을 위해 Patent Troll 활동을 참고하는 사례도 다수 나타나고 있다. 이미 Patent Troll이 하나의 사업영역으로 자리잡은 오늘에 있어 우리 기업들도 Troll행위에 대해 적극적으로 대응하는 한편으로 이들이 채택하고 있는 전략들을 분석하여 채용함으로써 특허관리를 통한 가치창출에 나서야 할 것이다.

The aim of this paper is to analyze Korean specific particles ‘i/ga’ and ‘eul/leul’ and show how to teach them effectively to foreign learners. In this respect, we first analysed some typical ‘i/ga’ or ‘eul/leul’ constructions: they seem very similar in appearance but their syntactic structures are quite different. We showed that in order to explain effectively ‘i/ga’ and ‘eul/leul’ constructions, the notion of ‘topic’ should be introduced and found that there exist some particular semantic restrictions between two successive noun phrases participating in ‘i/ga’ and ‘eul/leul’ constructions. Secondly, we tried to show how to construct the educational substance and method of these specific particles ‘i/ga’ and ‘eul/leul’. We proposed to introduce types of ‘i/ga’ and ‘eul/leul’ constructions, typical predicates used with these constructions, semantic restrictions of two successive noun phrases participating in these constructions, equivalent constructions corresponding to these constructions and their concrete examples in constructing the educational substance and method of the specific particles ‘i/ga’ and ‘eul/leul’.

This paper reports the results from a survey on the perception of e-learning at the higher level education. The resulting data consists of answers to the questionnaire by a total of 822 respondents including 609 students who were enrolled in either 2 year colleges, 4 year colleges, or graduate schools at the time when the survey was conducted, and 213 academic faculty and staff who hade-learning experience. Main findings are: first, the most preferred instructional material format for e-learning was web-based self-directed instruction (28.1%) by the faculty whereas students preferred discussion (24.6%) and Video on Demand (VOD) (24.1%) .. Secondly, students of e-learning classes studied more on average than the students of face-to-face classes and students with more e-learning experience had a tendency of studying more. Thirdly, students, academic faculty, and staff all reported heavier burdens with online classes than with offline classes, but the perception of increased burdens with online classes relative to offline classes was more widespread among faculty members (44. 7% at twice more burden) than among students (33.5% at twice more burden) .. Fourthly, overall students (56. 7%) are more satisfied with online classes than academic faculty and staff (43.4%). Fifthly, the willingness to participate in online classes by faculty (89. 7%) was higher than that of students (57.8%). Sixthly, as to the online tuition, students (50.3%) claim that less than 50% of the tuition of the offline education is optimal while academic faculty and staff (23.8%) reported 90%.

Prior to Six Sigma, many companies had adopted a policy management method designed to manage business performances through the top-down deployment of management policies. This policy management method and the Six Sigma CTQ Flow Down will make a good combination when their merits are developed and systemized as the management innovation program which enables to set up innovation targets along with management targets in the stage of strategic planning and to participate all the personnel from top management down in achieving th targets. This paper will help the companies implementing Six Sigma improve their management constitutions and achieve better management performances through the integration of policy management and Six Sigma.

Nanostructured materials exhibit attractive mechanical properties that are often superior to the performance of their coarse-grained counterparts. However, one major drawback is their low ductility, which limits their potential applications. In this paper, different strategies to obtain both high strength and enhanced ductility in nanostructured materials are reported for Ti-base and Zr-base alloys. The first approach consists of designing an in-situ composite microstructure containing ductile bcc or hop dendrites that are homogeneously dispersed in a nanostructured matrix. The second approach is related to refining the eutectic structure of a Ti-Fe-Sn alloy. For all these materials, the microstructure, mechanical properties, deformation and fracture mechanisms will be discussed.
