The question of what our cultural goods might have known in a major exporting market, has intrigued investigators since 2000 year. Actually, Maybe Korean cultural assets just didn't have time to get to know International or Asia market. But now, a new euphoria can be tasted, on the lips of the small but growing Korean Contents Mania, as New Korean Wave-Crust begin to welcome the priciest contents from korea. Given Asian's surging population for our entertainment contents-drama, movie, music, character, etc., and the sense of a positive response its newly international market, it is hardly surprising. Now, Korea Wave must play an important roles in our country- economy, business, specially. This paper is seeking in OSMU on Korean Contents in East-North Asian Market, and is developing about Korean Wave study model. and It also points to a different strategy for exporting cultural contents, suggesting it should be effected for model to OSMU.

Lipoma is the most common benign neoplasm of the body with rare occurrence in the oral cavity. It represents 1~4% of benign neoplasms of the mouth, which affect the buccal mucosa, floor of the mouth, tongue and lips. We report a case of lipoma in the labial vestibule with extraoral swelling, which could easily be misdiagnosed as an odontogenic abscess. Excisional biopsy in this case revealed well-circumscribed masses, surrounded by a thin fibrous capsule and composed of sheets of mature adipocytes, arranged in a "chicken wire" configuration. After a computed tomography scan, excisoinal biopsy was done, and there were no recurrence after 5-month follow-up period.

10years and 8 months old patient, who had been wearing Milwaukee brace for 5 months, was treated by multibanded system without extract on. She complianed severe protrusion and interdental spacing of upper anterior teeth. Cephalometric analysis revealed short anterior facial height, infraclusion of the lower first molars and severe profrusion of upper and lower anterior teeth. During orthodontic treatment Milwaukee brace was replaced by TLSO, so the orthopedic force on the dentofacial region was eliminated. After 2 years and 3 months, she gained raised bite, increased interincisal angle, salient reduction in the protrusion of upper central incisals with agreeable overjet, complete obliteration of interdental spacing and reduction of protrusion of upper and lower lips.

In this paper, we propse an object-oriented coding method in low bit-rate channels using pyramid structure and residual image compensation. In the motion estimation step, global motion is estimated using a set of multiresolution images constructed in a pyramid structure. We split an input image into two regions based on the gradient value. Regions with larte motions obtain observation points at low resolution level to guarantee robustness to noise and to satisfy a motion constraint equation whereas regions with local motions such as eye, and lips get observation points at the original resolution level. Local motion variations and intesity variations of an image reconstructed by the golbal motion are compensated additionally by using the previous residual image component. Finally, the model failure (MF) region is compensated by the pyramid mapping of the previous displaced frame difference (DFD). Computer simulation results show that the proposed method gives better performance that the convnetional one in terms of the peak signal to noise ratio (PSNR), compression ratio (CR), and computational complexity.

15년전 심방중격 결손증 진단을 받은 47세 남자 환자가 심도자 검사를 위해 입원하였다. 환자는 입술과 손톱에서 명확한 청색증을 보이고 있었으며 심한 폐동맥 고혈압을 나타내고 있었다. 본 환자는 지난 수년간 아이젠멩거 증후군으로 진단되어 대증적 치료만을 받아오고 있었다. 심도자 검사 후 환자는 흡입형 Iloprost 치료를 시작 하였으며 성공적으로 심방중격결손증 수술을 받을 수 있었다. 환자는 수술 후에도 치료를 지속하였다.

A mechanistic model is developed to predict the thrust force and cutting torque of drilling process including wear. A mechanistic oblique cutting force model is used to develop the drilling force model. The cutting lips are divided into small elements and elemental forces are calculated by multiplying the specific cutting pressure with the elemental chip area. The specific cutting pressure is a function of chip thickness, cutting velocity, rake angle and wear. The total forces are then computed by summing the elemental forces. Measured cutting forces are in good agreement with the simulated cutting forces.

Hausser (1999)와 이기용 (1999a, 1999c)에서는 데이터베이스 관리 시스템(DBMS)을 이용하여 자연언어의 의미를 다루는 데이터베이스 의미론을 제안하였다. 특히 이기용 (1999c)에서는 수형도(tree), 논리 형태(logical fomulas), 자질 구조(feature structure)와 같은 다양한 언어 표상 형식들을 관계형 데이터베이스 관리 시스템(DBMS)의 표상 형식인 테이블 형식으로 전환 가능함을 보임으로써 데이터베이스 의미론에 관계형 데이터베이스 관리 시스템을 도입할 수 있음을 제시하였다. 한편, Lee (2000)에서 제시한 데이터베이스 의미론 모형에서는 데이터베이스 관리 시스템과 사용자(end-user)를 연결하는 언어 정보 처리 시스템(LIPS; Linguistic Information Processing System)을 제안하였다. 이 언어 정보 처리 시스템은 사용자에 의해 입력된 언어 자료를 처리하여 그 분석 결과를 데이터베이스 관리 시스템에 전달하고, 이를 통해 구축된 데이터베이스에서 추출한 정보를 다시 사용자에게 전달하는 시스템이다. 이 논문은 한국어 '이, 히, 리, 기' 피동형을 전산처리 할 수 있도록, 데이터베이스 의미론에서 핵심 요소인 언어정보 처리 시스템과 데이터베이스 관리 시스템을 구현하는 것이 목적이다.

The purpose of this experimental study was to investigate characteristics of English vowels as spoken by Korean speakers. Ten English mono-syllabic words were spoken six times by six male college students who were born and raised in Seoul. Formant frequencies were measured from sound spectrograms made by the PC Quirer. Results showed that Korean speakers similarly pronounced /i/ and /I/, /u/ and /$\upsilon$/, and /$\varepsilon$/ and /${\ae}$/ respectively. It seems that Korean speakers can not differentiate tense vowels(/i/, /u/) from lax vowels(/i/, /$\upsilon$/) and pronounce low vowels such as /${\ae}$/, /a/, /c/ clearly. It is necessary that Korean speakers practice the correct movements of the jaw, tongue, and lips when they pronounce English vowels.

In an edentulous situation, the oral rehabilitation with complete denture is substantially different from treatment of natural teeth. The artificial teeth arrangement and occlusion are important factor for the stability of the denture. Bilateral balanced occlusion is that stability of the denture is attained when bilateral contacts exist throughout all excursion and static states of the denture during function and, artificial teeth are arrangement in neutral zone where the forces between the tongue and cheeks or lips are equal. This is how dentist make a favorable prognosis. Therefore, dentists are have to be a little more involved in the selection and arrangement of artificial teeth.

The critical factors affecting the esthetics of anterior implants can be summarized as following: 1) Correct positioning of implant fixture 2) Enough amount of alveolar bone 3) Optimum volume of soft tissue. The position of implant is probably the most important factor in obtaining esthetic treatment outcome. The 3-dimensional orientation of implant is determined by the position on the alveolar ridge and its direction. Clinicians often try to mimic natural teeth when fabricating restorations. During the course of esthetic diagnosis and treatment, however, one should not forget to consider the correlation between facial pattern, lips, gingiva, alveolar ridge, as well as remaining dentition. Since anterior region is biologically unfavorable when compared with posterior region, one minor discrepancy in positioning of implant can cause esthetically undesirable treatment outcome. If one understands the biological and prosthetic meaning of implant's 3-dimensional position, he or she can achieve superior esthetic outcome in anterior region.
