These is facial asymmetry in most people, to a certain degree. In its severe case, especially facial asymmetry with mandibular prognathism, improvement of esthetic problem as well as decreased functional masticatory efficacy due to malocclusion are important. It is widely accepted that the facial asymmetry occurs primarily at mandible, compensatory maxillary movement occurs secondary. Therefore, as trying analysis and classification of facial asymmetry, there is the primary concern on the mandible. Particular methods are used for evaluation of all patient with facial asymmetry as following ; clinical visual exammintion, lateral and P-A cephalometric analysis, submentovertex view, scintigram, cast analysis, and face-bow transfer. We experienced 3 cases of facial asymmetry with mandibular prognathism complaining of facial asymmetry and mastication difficulty. Through preoperative orthodontic treatment, orthognathic surgery, and postoperative orthodontic treatment, we achievd esthetic and functional good result.

This is a retrospective study by arthrographic, clinical, surgical, and histopathologic examination based on a series of 38 patients, 40 joints having anterior meniscal displacement with perforation of the 278 patients, 336 joints who had diagnosed as TMJ internal derangement by use of TMJ arthrography at department of Oral & Maxillofacial Surgery, Pohang Hospital, College of Medicine, Dongguk University. 1. In the 278 patients, 336 joints who had diagnosed as internal derangement, anterior meniscal displacement with perforation was 11.9% in 38 patients, 40 joints. 2. The false positive finding that occurred by arthrography of anterior meniscal displacement with perforation could be prevented by two times of diagnostic and preoperative with accumulating experience and accurate technique, and arthrography was very valuable in diagnosis of meniscal perforation. 3. The radiographical condyle morphology of anterior meniscal displacement with perforation was all abnormal and small condyle was the highest group in incidence as 40.0%. 4. The ratio of Male/Female in anterior meniscal displacement with perforation was about 1:5, the mean age was 43.6 years old, over 30 years old was 84.3%, and we could not find any difference of TMJ site in meniscal perforation. 5. In the clinical symptoms of anterior meniscal displacement with perforation, crepitus was 94.8%, pain was 73.9%, and limitation of mouth opening was 41.9%. Therefore, we could know that crepitus is diagnostic criterion in meniscal perforation. 6. The mean of preoperative mouth opening in anterior meniscal displacement with perforation was 3.14mm and the mean of postoperative mouth opening was 37.9mm. Therefore, preoperative limitation of mouth opening was largely resolve. 7. In the location of meniscus perforation, posterior attachment was the highest group in incidence as 75.0% and the mean size of meniscal perforation was 6.8mm in diameter. 8. All of anterior meniscal displacement with perforation was treated by surgical operation. The meniscoplasty was 70.0% and the meniscectomy was 30.0%. In the postoperative prognosis, the meniscoplasy was 85.8% in the meniscectomy was 83.3% in success rate. 9. In the histopathologic staging of removed soft tissue of anterior meniscal displacement with perforation, Grade 5 Degeneration was the highest group in incidence as 35.0% and the mean Grade was 4.4 Grade. The Grade 4, 5, 6 Degeneration were 75.0% of all, and so interstitial hyalinization and cartilaginous metaplasia were abundant.

마케팅 커뮤니케이션 메시지가 기업태도에 미치는 영향 : 소비자의 가치에 의한 상호작용 효과를 중심으로

김재휘,김수정 한국방송광고공사 2005 광고연구 Vol.0 No.69

본 연구는 기업의 마케팅 커뮤니케이션 메시지 전략에 대해 관심을 두고, 기업의 마케팅커뮤니케이션 메시지가 소비자의 기업에 대한 태도에 영향을 미치는지, 그리고 이러한 영향이 소비자의 가치에 따라 어떻게 달라지는지 알아보고자 하였다. 이를 위해, 소비자의 가치를 측정하고, 두 가지 메시지(기업의 능력 및 기업의 사회적 책임 메시지)를 노출한 후 기업태도를 측정하였다. C대학에 재학 중인 257명을 대상으로 실험을 실시하였으며, 연구결과, 기업의 사회적 책임을 강조한 마케팅 커뮤니케이션 메시지가 기업의 능력을 강조한 경우보다 기업에 대한 태도가 더 긍정적으로 나타났다. 그리고 기업의 마케팅 커뮤니케이션 메시지의 유형과 소비자의 가치 사이에는 상호작용 효과가 나타났다. 즉, 기업의 마케팅 커뮤니케이션 메시지가 소비자의 기업태도에 미치는 영향은 소비자의 가치에 따라서 다르게 나타난다는 것을 확인할 수 있었다. 구체적으로, 윤리경영을 중시하는 소비자나 소비자 욕구를 중시하는 소비자들은 기업의 사회적 책임을 강조하는 메시지에 의해 긍정적인 기업 태도를 형성하는 것으로 나타났으나, 이와 반대로, 서비스를 중시하는 소비자나 성실·정확한 정보를 중시하는 소비자는 기업의 능력을 강조하는 마케팅 커뮤니케이션 메시지를 통해 긍정적인 기업태도를 형성하는 것으로 나타났다. This study focused on corporate marketing communication message strategy and investigated it’s the influence on consumer attitude toward corporations, specifically focusing on consumer value. First, the consumers’ value of the corporation was measured. Then, to measure the consumers’ attitude toward the corporation, messages were mixed, representing corporate ability(CA) and corporate social responsibility(CSR). A total of 257 undergraduate students participated in the experiment as subjects. The results of the experimental analysis found that consumers’ attitude toward a corporation were more favorable when they were exposed to the corporate marketing communication message related to the corporate social responsibility than when they were exposed to the one related to the corporate ability. An interaction effect was found between corporate marketing communication message and consumer values. The influence of corporate marketing communication messages on consumers’ attitudes toward a corporation may be different depending on consumers individual values. Concretely, as consumers value ethical management and consumer-centered value higher, positive corporate attitudes were shaped through corporate social responsibility message. As consumer value excellent services and precise information value higher, it was indicated that positive corporate attitudes were formed through corporate ability message. This study has shown that the influence of the corporate marketing communication message type on consumers’ attitude toward a corporation is dependent on consumer values. The implication and limitations of this research are discussed.

朴永圭,李哲熙,鄭輝洙 嶺南大學校 環境問題硏究所 1986 環境硏究 Vol.6 No.1

The results of the multivaraite analysis in order to estimate water quality of the Kum-ho river were as follows: 1. The water quality of the Kum-ho river estimated by the factor scores were seasonably homogeneous throughout the period of this research. 2. The cumulative proportion includings the third principal components was ranked as high as 97.8%. 3. The first principal components except water temperature, which the factor loading of which marked over 0.9, are composed of 14 items of water quality, and it was thought to be closely related to the river pollution caused by human activities and the waste water from near by factories. 4. In the relationship between the water quality and the flow of Kum-ho river was founded that COD and the factor scores related closely to each other from the relationship. Therefore, the run-off loading rate could be explained most completely by COD(Cr) and factor scores. And the run-off loading rate of the Kum-ho river basin showed almost no variation at the lower reaches, where the pollutions were mainly contributed by the point sources.

우리 영동대학교에서 1998년 이후 지금까지 진행하여 온 특별 주제 학습과정인 STC(Special Topics COurse)프로그램을 기존의 운영틀에서 탈피하여 한층 더 발전시킨 복합STC로 활용하고자 하였으며, 특히 이를 졸업생의 취업 및 진학의 방법으로 최대한 활용하고자 계획·운영하였다. 그 결과 취업 및 진학과 같은 진로 확립은 물론 전공지식의 확대, 자격시험 대비능력의 향상, 학생과 교수간의 유대강화 등과 같은 괄목할 만한 성과를 얻을 수 있었으며, 교수들의 산업체 방문을 통한 산학협동의 계기 마련에도 커다란 성과를 얻었다. We have upgraded the STC(Special Topics Course) program, which has been carried out in our university since 1995, to more structured program so that we could train our chemical engineering students better. This program was geared to help students find better jobs and enter well-recognized graduate schools. Consequently, we had most students successful in job searches as well as entrance exams for graduate school; besides, those who actively participated in our STC program were able to attain better professional knowledge and acquire various professional engineers certificates. On top of that, this program allowed us to build up closer relationships with our students. We also made university-industry cooperation possible through our visits to industries nearby.

Orthognathic surgery and temporomandibular joint symptoms

Jung, Hwi-Dong,Kim, Sang Yoon,Park, Hyung-Sik,Jung, Young-Soo Korean Association of Maxillofacial Plastic and Re 2015 Maxillofacial Plastic Reconstructive Surgery Vol.37 No.-

The aim of this article is to review temporomandibular joint symptoms as well as the effects of orthognathic surgery(OGS) on temporomandibular joint(TMJ). The causes of temporomandibular joint disease(TMD) are multifactorial, and the symptoms of TMD manifest as a limited range of motion of mandible, pain in masticatory muscles and TMJ, Joint noise (clicking, popping, or crepitus), myofascial pain, and other functional limitations. Treatment must be started based on the proper diagnosis, and almost symptoms could be subsided by reversible options. Minimally invasive options and open arthroplasty are also available following reversible treatment when indicated. TMD manifesting in a variety of symptoms, also can apply abnormal stress to mandibular condyles and affect its growth pattern of mandible. Thus, adaptive developmental changes on mandibular condyles and post-developmental degenerative changes of mandibular condyles can create alteration on facial skeleton and occlusion. The changes of facial skeleton in DFD patients following OGS have an impact on TMJ, masticatory musculature, and surrounding soft tissues, and the changes of TMJ symptoms. Maxillofacial surgeons must remind that any surgical procedures involving mandibular osteotomy can directly affect TMJ symptoms, thus pre-existing TMJ symptoms and diagnoses should be considered prior to treatment planning and OGS.

선천성 기형환자에서의 악교정수술 적용과 수술 증례 분석

정휘동(Hwi-Dong Jung),정영수(Young-Soo Jung) 대한치과의사협회 2012 대한치과의사협회지 Vol.50 No.11

Distraction osteogenesis and orthognathic surgery are the widely used surgical methods for treating hemifacial microsomia and cleft lip and palate, the representative forms of congenital deformity. Distraction osteogenesis is an outstanding treatment of choice when more traction is needed than what can be achieved by general orthognathic surgery. However, the stability of distraction osteogenesis has not yet been established, and in most of the cases, additional orthognathic surgery is mandatory. Moreover, the difficulty in precise control of the traction directions is another disadvantage of distraction osteogenesis. Therefore, it would be desirable not to conduct distraction osteogenesis when the patient is suitable for an orthognathic surgery. Also, distraction osteogenesis should be recognized as an accessorial method of treatment, and be used restrictively.
