In content-base video data retrieval, the detection for scene change is needed. Color histogram approaches are generally used. Color histogram approaches are simple and more robust to object and camera movements but they ignore the spatial information and fail when two different frames have similar histograms. We propose a new algorithm to use color histogram and entropy to enhance the false-positive occurred by brightness variation and the miss by similar color histogram. At the experiments, it is more robust to brightness variation and have spatial information.

Previous investigation regarding the relationship between the religion and mental health yielded equivocal and inconclusive results. There are many reasons for the inconsistency in the results. The most important reason for it is that investigators overlooked the fact that people were religious in different way. According to Allport religious orientation can be defined within two basic categories. He assumed the extrinsic religious orientation characterizes the immature person who tends to use religion instrumentally, while intrinsic religious orientation is found in more mature person, the one committed to religious values as ultimate. In order to provide a means of assessing the religious orientation, Allport developed "Religious Orientation Scale"(ROS), focusing on extrinsic-intrinsic continuum. But research extrinsic and intrinsic religious orientation has been troubled by conceptual diffuseness and questionable scale validity. The objective of this study is to develop the Korean "Religious Orientation Scale"(ROS) having higher validity, reliability and item-to-scale correlates, to assess the relationship between religious orientation and dysfuctional behavior and self-differentiation, and to investigate the relationship between religious orientation and religious problem-solving style. Three important conclusions may be drawn from this study. First, for the time in Korea "Religious Orientation Scale"(ROS) was successfully developed. In a factor analysis(principal components method with varimax rotation) two factors appeared as predicated. The results of data analysis indicated ROS is a highly reliable and valid assessment instrument. Second, the relationship between religious orientation and dysfuctional behavior and self-differentiation were investigated. The results of this investigation revealed that extrinsic religious orientation was positively related to the eight subscales of Derogatis' Symtom Checklist-90-Revision, while intrinsic religious orientation was negatively related to these. And extrinsic and religious orientation was negatively related to the level of self-differentiation, while intrinsic religious orientation was positively related to it. Third, Pearson correlations were conducted to assess the relationship between the three problem-solving styles (Self-directing, Defering, Collaborative) and religious orientation. The results provided a sharper picture of the unique correlates of the three problem-solving styles. Extrinsic religious orientation correlated significantly with defering problem-solving style. In contrast, intrinsic religious orientation related positively to collaborative and self-directive problem-solving style.
漁船船員敎育의 問題點과 그 對策에 關하여 : IMCO / STCW 협약을 중심으로
裵錫悌 군산대학교 1980 群山水産專門大學 硏究報告 Vol.14 No.2
IMCO/STCW convention was enacted for the purpose of protect the environment of the sea and the saftey of life at the sea, but the existing marine officer's law has many diffcult problems to solve the quali-fication of the crew and the license system according to the requirement of minimum knowledge and manda-tory minimum requirement for the certification of master and officer by the STCW convention. Accordingly, the training for officer who engaged in fishing vessel must be varied in accordance with the international trend. In this thesis I have revealed the practical problems of developing the crew's quality and reform the license system in the fishing vessel.

Sinonasal mucormycosis is a form of invasive fungal infection of the sinonasal track that often extends to the orbit, brain, and palate. It is caused by the order Mucorales and commonly associated with immuconcompromised conditions such as diabetic ketoacidosis, HIV infection, hematologic malignancy. Treatment includes aggressive debridement, systemic antifungal therapy and control of underlying factors. We experienced 3 cases of sinonasal mucormycosis: rhino-orbital, isolated sphenoid sinus, palatal mucormycosis. Each patients had undergone wide surgical debridement including a case with orbital exenteration and systemic antifungal therapy. We present our successful management with literature reviews. 비·부비동에 발생하는 모균증은 안와, 두 개내, 또는 구개 침범이 흔한 진균성 감염이고 mucorales종의 일종으로 당뇨병케토산증이나 AIDS환자, 혈액 악성종양과 같이 면역이 저하된 환자에게서 주로 발생한다. 치료로는 환자의 원인 요소를 치료하고 광범위한 수술적 절제와 장기간의 항진균제의 사용이 이용되고 있지만 치료효과가 만족하지 못하다. 저자들은 안구를 침범하여 안구를 제거한 경우, 장기간의 두통을 호소한 환자에게서 발견된 접형동 단독의 감염 사례, 그리고 구개를 침범하여 구개의 일부를 절제한 사례를 경험하였고 광범위한 감염부위의 절제와 장기간의 항진균제 치료를 이용하여 완치하였기에 문헌 고찰과 함께 보고하고자 한다.
기동 유무 판별 기준의 변화에 따른 기동표적의 추적 성능 비교
박제홍,이우주,임상석 한국항행학회 2002 韓國航行學會論文誌 Vol.6 No.3
표적 추적에서 기동은 오랫동안 다루기 어려운 문제로 여겨져 왔다. 이러한 문제를 극복하기 위해 기동을 처리하는 여러 가지 기법들이 연구, 개발되었다. 그러나 이러한 기법들의 연구에 있어 지금까지 기동 검출 기준차의 변화에 대한 필터의 성능의 편차에 대한 연구는 이루어지지 않고 있어 기동에 따른 적절한 기동 검출 기준치의 설정이 객관적인 기준없이 이루어지고 있는 것이 현실이다. 본 논문에서는 기동 표적 추적용 필터에 있어 여러가지 기동에 대해 기동 유무 검출 기준치의 변화가 필터에 미치는 영향을 알아보고, 이를 분석함으로써 기동과 기동탐지 기준치와 상관관계를 실험적으로 규명하였다. For a long time target maneuvers in tracking problem have been a difficult task to handle. In order to solve this problems, there have been various tracking techniques. In the development of a tracking filter for a maneuvering target, maneuver detection threshold plays a key role. However, no study of filter performance the varying maneuver detection threshold has been carried out so far. In stead, the maneuver detection have been chosen empirically. In this paper, the effect of detection threshold selection on the performance of the tracking filters was considered and the relationships between maneuvers and the detection threshold have been analyzed by simulation.

The seamen's act was enacted for the purpose of protect the crw's fundermental life and in order to operate the boat safely keeping rules on board, however, In the fishing vessel every exertion condition is worse than any other vessels as to the seamen's wage, boarding contract, application, public welfare aspect. It is necessary to replenish an institution to protect a number of fishermen's right and interest and their well being based on the stable foundation between employer and employee. According to the research of basic labor condition of fishermen I have investigated the following aspects respectively The results are as follows. 1.The seamen's wage was paid at the low cost consiting of minimum guaranteed wage in-stead of excessive labor. 2.As their distribution of Individual Income is determined according to the amount of fishing, Even the fundermental life of human-being was disregarded on account of Fishing practices. 3.With rack of Institutional protection of basic life it has come to bring severe loss to the crew's right and interest.
인터넷 광고에서 방문 횟수를 측정하는 암호학적 방법들에 관한 고찰

본 논문에서는 웹 광고에서 웹사이트를 방문하려는 고객과 서버(예를 들어, 웹사이트 발행자들)간에 상호작용을 측정하기 위한 안전하고도 효율적인 측정 방법들에 관해 살펴보고자 한다. 대개의 웹 광고는 많은 고객들과 서버들 그리고 서버들에 의해 제공된 고객들의 수 에 관한 정보를 수집하는 감사 기관의 상호작용으로 이루어진다. 이때, 대부분의 서버들은 실제 제공되는 것보다는 훨씬 많은 수의 방문 정보를 감사기관에게 제시함으로서 보다 많은 광고 수익을 얻고자 한다. 이에 본 논문에서는 과장된 서버로부터의 방문기록을 막는 암호학적으로 안전한 몇 가지 측정 방법들을 소개하고자 한다. 아울러 이들 측정 방법들은 전반적인 통신 트래픽 이라든가 다른 부수적인 오버헤드가 부가되지 않을 만큼 효율적이어야 할 것이다. In this paper we study on secure and efficient metering schemes to measure the interaction between clients and servers(e.g. the web site publishers) on the web advertisements. In a representative scenario there are many clients and servers, and an audit agency should collect information about the number of clients that were served by each server. A typical server is motivated to claim that it served many more clients than it has actually served. We introduce some metering schemes which are cryptographically secure and prevent servers from inflating the count of their visits. At the same time the metering schemes should be efficient and do not add a considerable overhead to the different parties and to the overall communication traffic.
有機溶劑染色에 의한 PET Filament 의 染色性과 物性變化에 관한 硏究
鄭濟石,李相奎 단국대학교 1989 論文集 Vol.23 No.-
Poly(ethylene terephthalate) filament was dyed with C.I. Disperse Orange 3 in DMF, MCB, and PER dyebath at varying temperature in order to examine the dyeing properties related with the changes in the physical properties. The results of experiment were as follows; 1. Amount of dye uptake decreased in order of PER, MCB, and DMF, and diffusion coefficients of dye were increased according to increasing temperature, but amount of dye uptake were deacreased. 2. Shrinkage and degree of swelling in DMF which interacted with the aliphatic residue of PET were shown better than other solvents. 3. Dye exhausion rate increased the linear proportion with the change in the physical properties increased until the equilibrium dye uptake. 4. In isothermalic condition, degree of crystallinity was increased as time pass.
