Fibrous dysplasia is believed to be a hamartomatous developmental lesion of unknown origin. This disease is divided into monostotic and polyostotic fibrous dysplasia. Polyostotic type can be divided into craniofacial type, Lichtenstein-Jaffe type, and McCune-Albright syndrome. In this case, a 31-year-old female presented spontaneous loss of right mandibular teeth before 5 years and has shown continuous expansion of right mandibular alveolus. Through the radiographic view, the coarse pattern of the mixed radiopaque-lucent lesion was seen on the right mandibular body, and there was diffuse pattern of the mixed radiopaque-lucent lesion with ill-defined margin in the left mandibular body. In the right calvarium, the lesion had cotton-wool appearance. Partial excision for contouring, multiple extraction, and alveoloplasty were accomplished under general anesthesia for supportive treatment. Finally we could conclude this case was polyostotic fibrous dysplasia of cranio-maxillofacial area based on the clinical, radiologic finding, and histopathologic examination.

At present, the scale of Electronic Commerce through internet has been rapidly increasing due to the development of information & communication technology, and aggregated to 2.4 billion dollar in America last year (1998). The market scale of worldwide electronic commerce is also presumed to be about 130 billion dollar in 2000, and to occupy more than 20% of the whole world trade in world 2020. Since the right of trademark, despite of being effective only in registered nations on the principle of territorialism, is unified on the cyber space of internet without domestic barrier or local limitation which make it easier to conduct the distribution of information rapidly through the address-internet domain name, those are very important that the systematic dispute-solving plan on problems such as decision of its Act and international jurisdiction to be established, in an effort to prevent the newly emerging dispute instances such as trademark infringement and improper competitiveness. In addition, it is natural that on the threshold of the electronic commerce age which formed with an unified area without the worldwide specific regulation, each country including us makes haste with the enactment of "electronic commerce Act" aiming at coming into force in 1999, in keeping with getting through "non-tariff law on electronic commerce" by U. S. parliament on May, 1998. In view of the properties of electronic commerce transactions through internet, there are the large curtailment of distributive channel, surmounting of restrictions on transaction area, space and time and the easy feedback with consumer and the cheap-required capital, from which the problems may arise - registration of trademark, the trademark infringement of domain name and the protection of prestigious trademark. Therefore, it is necessary to take the counter-measure, with a view of reviewing the infringement of trademark and domain name and the instances of each national precedent and to preventing the disputes. The improvement of the persistent system should be needed to propel the harmonious protection of those holding trademark right's credit and demanders' expectant profit by way of the righteous use of trademark.

예술, 그 중에서도 문학은 인류의 감성에 늘 붙어 이야기하면서 글을 접한 타자를 울리기도 하고 웃기기도 한다. 그러한 문학의 치료적 기능의 관점에서 시를 어떻게 써야 하는지에 대한 통찰은 매우 유익한 것으로 기억될 것이다. 삶이라는 무형적 정형의 틀에 대한 문학의 치료적 효과는 물론 정형의 시에서 극한의 결과를 획득할 수 있다. 그러면, 정형의 틀 안에 어떻게 자유로운 인체의 뉴런에 관계된 면역시스템이나 문학의 약을 스며들게 할 것인가에 대한 탐색은 더욱 더 우리의 창작적 기법의 필요를 가중시킨다. 본 연구를 통해 "올바른 한국의 정형시 '시조' 쓰기"는 문학치료 효과를 더욱 확장시키며 삶의 질을 풍요롭게 해주는 것으로 판단되었다. 본고는 그러한 글쓰기 혹은 마음 쓰기에 대한 방법론을 제시하려고 한다.

A 10 years old female Poodle weighing 4.38 kg and a 10 years old female Maltese weighing 4.33kg were referred to veterinary leaching hospital of college of veterinary medicine, Konkuk uni-versity because of hematuria and severa anorexia. Preoperative hematological and srum chemical values revealed that counts of WBC were $78.4{\times}10^3$,/TEX>/ul in the Poodle and $21.6{\times}10^3$in the Maltese, concentrations of BUN 105 and 13 mg/dl, concentrations of creatinine 4.0 and 1.4 mg/dl, concentration of ALKP 542 U/L in the Poodle and concentration of ALF 37 U/L in the Maltese, respectively. Radiographic findings were observed radiopaque bilateral nephroliths in the Poodle and right renal cal- culus in the Maltese. Ultrasonographic findings were showed hyperechoic mass with severe acoustic shadowing, which were ]ocated in the center of both kidneys parenchyma in the Poodle and in right kidney in the Maltese. Bisectional nephrotomy in right kidney for removal of calculus, which had ,sin- gle stone and more large than splitted stones in lets kidney in the Poodle, was performed under isnf- lurane anesthesia in 100% $O_2$. The time from temporary occlusion of blood flow to suture of incisioned kidney after removal of renal calculi was elapsed 12 minutes. During operation and until 24hrs after operation was infusioned mannitol and tranexanic acid solution. There were normal urination with yellow color in the Poodle at 3 days after operation and in the Maltese at 1 day and good appetite after 7 days and 1 day after operation. At 7 days and 9 days after operation, hematolgoical and seam chemical values repealed that counts of WBC were $29.8{\times}10^3/u1 in the Poodle and 13.1 {\itmes}10^3$/ul in the Mal- tese, concentrations of BUN 13 and 10 mg/dl. concentrations of creatinine 1.3 and 1.1 mg/dl, con-centrations of ALT 34 and 97U/L, concentraion of AST 10 U/L in the Poodle, respectively, By ultra-sonographic view there was not observed hyperechoic mass and radippaque calculus in operated kid-ney in radiographic view.

DC 및 LC에 대하여 증명 가능한 안전성을 제공하는 2-블록 구조를 라운드 함수의 위치에 따라 서 C(Center)-형 R(Right)형 L(Left)-형으로 구분하고 각각에 대한 고차 차분 공격 측면의 안전성을 분 석한다. 4라운드 암호화 함수인 경우 세가지 2-블록 구조는 고차 차분 공격에 대하여 동일 한 안전성을 제공한다는 사실을 증명하며 5라운드 이상의 암호화 함수에 대해서는 병렬 연산이 가능한 R-형 구조가 C-형과 l-형에 비해서 계산 효율성은 높지만 고차 차분 공격 측면의 안전성은 떨어진다는 사실을 밝힌 다. We study on the security for the block ciphers with 20block structure which have provable security against DC and LC on the view point of higher order DC, 2-block structures are classified three types according to the location of round function such as C(Center)-type R(Right)-type and L(Left)-type We prove that in the case of 4 rounds encryption function these three types provide the equal strength against higher order DC and that in the case of 5 or more rounds R-type is weaker than C-type and L-type.

This study examined the field of view of older drivers based on their eye points. The subjects were 25 people whose age was over 65 years and 10 contrasting subjects on their 20s. For the experiment, we expanded the width of the A-pillar of a test vehicle. With a measuring apparatus designed for the study, we analyzed 3 axes of coordinates from glabella to a fixed point of the vehicle that would be used as CAD data of vehicle design. Result shows that average eye point of the older subjects was located significantly farther from the seat than that of the 20s approximately by 31.62mm(p=0.05). It was also found that the Binocular FOV was not significantly different between the older subjects and the 20s(p=0.85), and the effect of the width of the A-pillar on the FOV could not be found. We also measured the left and right side of the Ambinocular FOV of the older subjects. It was found that the older subjects had much wider visual angle than the 20s by 2.84 degree (F=4.78, p=0.01) on the left side, while the 20s showed significantly wider average angle than the older subjects by about 4.88 degree (F=4.78, p<0.05) on the right side. The results of this study can be used to improve the FOV based on the optimal eye points when designing a vehicle for older drivers.

Background : The human being and the bacteria have accomplished a balance and have coexisted each other during long time. Probiotics have evolved with the human host to exist and the result they have operated profitably to human host. So it requires that the functions of probiotics are expounded in view of Traditional Korean Medicine. Aim : Suggest the functions of probiotics in view of Traditional Korean Medicine. Method : The author's research has been performed to review the related references. Results : Probiotics assist the absorption of the lactose, proteins and minerals and product several kinds of vitamins, organic acids. Probiotics suppresses the growth of noxious bacteria and the production of harmful substances or gases. They absorbed and discharge the bile acid, and thus help us maintain the optimal level of blood cholesterol concentration. They can reinforce the immune response of the mucous membrane and control the hypersensitivity immune reaction such as asthma, atopy on the other hand. Probiotics have right functions as above and so can be applied widely in treatment of various disease and symptom. Conclusion : Considering the functions of probiotics in view of Traditional Korean Medicine, they participate in our spleen-earth-system (digestion and synthesis) and liver-wood-system (regulation of digestion, metabolism, internal secretion etc.), assist the function of lung-metal system(respiration and regulation of water metabolism) and regulate wi-chi (reinforce/control immune system). Consequently, hereafter there would be a necessity of control a circumstance in treatment of various diseases under these categories that probiotics should be able to do their right functions inside the human body.

본 논문에서는 하나 또는 그 이상의 얼굴, 기울어진 얼굴들이 존재하는 칼라 영상에 대해서 색상 및 코의 길이와 턱의 위치를 이용하여 측면 얼굴만을 검출하는 새로운 방법을 제안하였다. RGB 영상을 YCbCr 좌표계로 변환한 후, 피부색 정보를 이용하여 얼굴 후보 영역을 추출하였다. 추출된 후보 영역은 형태학적 필터링을 거치고 최종적으로 남게된 영역들은 레이블링된다. 또한 코의 돌출 부위의 특성을 이용하여 기울어진 얼굴 영상에 대한 기울기 보정을 하였다. 그리고 코 영역 부분의 수직 거리와 턱까지의 거리와 같은 지형적인 특성을 이용하여 수직축을 기준으로 좌우 45도 이내로 기울어진 측면 얼굴에 대해서도 강건하게 검출하였고 100개의 실험영상을 사용하여 92%의 검출율을 얻었다.
