양재영,임대호,Yang, Jae-Young,Leem, Dae-Ho 대한악안면성형재건외과학회 2012 Maxillofacial Plastic Reconstructive Surgery Vol.34 No.5

Osteochondroma is one of the most common benign tumors that occur in the bone, but in the head and neck region, osteochondroma appears rarely. Malocclusion, temporomandiublar disorders and facial asymmetry can occur in most cases with osteochondroma of the mandibular condyle. Most surgeons prefer massive removal of osteochondroma and reconstruction of condyle, simultaneously, to prevent various complications, such as a lateral open bite on the contralateral side. We report a surgical treatment and reconstruction of osteochondroma on a mandibular condyle through intraoral approach.

양재영,이호재,고영희,권병목,전효곤,Yang Jae-Young,Lee Ho-Jae,Kho Yung-Hee,Kwon Byoung-Mok,Chun Hyo Kon 한국생명과학회 2005 생명과학회지 Vol.15 No.2

기질 금속단백분해효소(MMP)는 기저막이나 간질성 조직 등에 있는 세포외기질 성분을 분해하여 상처 치유, 태아의 발생, 종양세포의 침윤과 전이 등을 포함하여 조직이 재구성되는 과정에서 생리학적 및 병리학적인 과정 양쪽 모두에 매우 중요한 역할을 한다. 본 연구에서는 MMP-9 유전자의 발현을 억제하는 물질을 천연물에서 탐색하였고, 탐색된 시료 중에서 높은 역가를 가진 낙우송과의 Metasequoia glyptostroboides가 선택되었다. 여러 가지 flavonoid 성분을 가지고 있는 Metasequoia glyptostroboides를 이용하여 4개의 biflavonoid와 2개의 monoflavonoid 구조의 물질을 분리하였고, 이 flavonoid들은 sciadopitysin, isoginkgetin, bilobetin, 2, 3-dihydrohino-kiflavone, luteolin, apigenin으로 정제하여 구조를 밝히고 zymography, WST-1을 이용한 세포독성시험, northern blot 등의 실험을 통하여 각 화합물의 구조적인 특성과 함께 MMP-9 유전자 발현을 억제하는 효과가 있는 것을 확인하였다. Matrix metalloproteinases (MMPs) are a family of structurally and functionally related zinc-dependent enzymes responsible for proteolytic degradation of extracellular matrix components such as base membrane or interstitial stroma. MMPs play an important role in a variety of physiological and pathological tissue remodeling processes, including wound healing, embryo implantation, tumor invasion and metastasis. Since MMP-9 (gelatinase B) has unique ability to cleave type IV collagen, gene expression of MMP-9 has been focused on as a pharmacological target. Flavonoids are a class of compounds that are widely spread in plants. In the coures of screening for the suppressors of MMP-9 gene expression from natural products, Metasequoia glyptostroboides was selected. Six flavonoids, sciadopitysin, isoginkgetin, bilobetin, 2,3-dihydrohinokiflavone, luteolin and apigenin were purified as suppressors of MMP-9 gene expression from M. glyptostroboides. The suppressing activity of the isolated flavinoids on the MMP-9 gene expression was measured by gelatin zymography and Nothern blot analysis.

한국 목조건축의 삼중량(三重樑) 가구(架構)에 관한 연구

양재영,Yang, Jae-Young 한국건축역사학회 2008 건축역사연구 Vol.17 No.3

The purpose of this study is to discover the characteristics and the change of the framed structure with triple beam. 61 existing buildings with the triple beam structure were selected and analyzed extensively. The result of this study could be described in detail like below. The triple beam structure is used in the highly graded and symbolized building like the Buddhist sanctum and the Confucian sanctum. And the triple beam structure was chiefly used in $1600{\sim}1800's$. Generally, 1 Koju-type with Toikan(退間) is applied to the triple beam structure. Despite of the sameness of framed structure, there is a tendency that the rear Toikan(後退間) is used in the Buddhist sanctum and the front Toikan(前退間) is used in the Confucian sanctum. This different application of the Toikan(退間) resulted from the different spatial characteristics which reflect function and grade of the building. The application of Sangjungdori(上中道里, upper purlin) and two Danyeon(短椽, short rafter) is a necessary consequence, because Jungbo(중보, middle beam) is located between Daebo(대보, beam) and Jongbo(종보, small and high located beam) as an additional member of frame. And these are essential characteristics of the framed structure with triple beam. The triple beam structure is formed in a transitional period, as the result from eliminating the inner high-column from the 2 Koju and double beam structure. Though the Daebo is longer, the structure is more stable. But the rate of application of the triple beam structure is low, because it does not exceed the double beam structure in merits. Some of buildings with the triple beam structure has the asymmetrical characteristic in design, which is appeared in the latter period of Joseon Dynasty.

The purpose of this study is to study how teacher’s behavior perceived by university students participating in liberal physical education class influences their intrinsic motivation. The subjects were 234 students (188 males, 56 females) participating in physical education classes such as tennis, bowling, badminton and golf for one semester in 2016. They completed three questionnaires which were designed to measure perceptions of teaching behavior, psychological needs and intrinsic motivation. Collected data were analyzed by using path analysis to verify a causal relationship among three research variables as research hypothesis. The results indicated that students’ perceived teaching behavior influenced their intrinsic motivation through the satisfaction of their psychological needs. Specifically, the results emphasized that relationship supportive behavior from teacher had significant impact on students’ intrinsic motivation. Practical teaching approaches based on the results are required to discuss.

e비즈니스와 특허법 - 기업의 기술과 정보의 보호대책을 중심으로 : e비즈니스와 특허법

양재영(Yang Jae-Young) 한국전자상거래학회 2007 전자상거래학회지 Vol.8 No.2

기술은 짧은 시간 내 개발하기 어렵고 또한 개발 후에도 특허 등 보호조치를 해서 타 경쟁사가 쉽게 습득하지 못하도록 해야 차별화된 경쟁력을 가질 수 있다. 이런 측면에서 특허는 기술보호의 중심점에 서 있다고 볼 수 있는데, 특허제도의 특성상 기술 선진국은 자국이 개발한 기술에 대해 후진국에서도 보호가 가능하도록 특허시장의 개방을 요구하는 반면, 기술 후진국은 선진국이 자국에서 기술 독점권을 행사하면 관련 산업의 위축과 기술개발에 장애가 될 수 있어 법으로 인정 범위를 국한하고 자국산업을 보호하는 등 폐쇄적인 특허제도를 운영하고 있는 실정이다. 미국에서는 지적 재산권 관련 법규를 강화하고, 일본에서는 지적재산권의 보호를 위해 단속을 강화하는 등 선진국을 중심으로 지적재산권 보호가 점차 강화 되어가는 추세를 보이고 있다. 최근 우리나라 기업들이 외국으로부터 특허권을 둘러싼 소송에 휩싸이는 일이 증가하고 있는 것도 이러한 추세를 보여주고 있는 것이 아닌가 생각된다. 지적재산권 보호를 위한 국가적인 대책 마련은 물론 기업 차원에서도 그에 대한 대비를 해야 할 것이다. 본 논문에서는 e비즈니스에 대한 법적분쟁을 없애는 차원에서 특허권과 발명의 개념 및 특허행정상의 발명으로 인정되지 않는 유형, 특허권의 효력 및 소프트웨어의 특허, 각국의 소프트웨어 및 BM특허의 현황 및 기업의 기술과 정보의 보호를 위한 대책을 중심으로 고찰한다. Since current Korean patent law was enacted in 1961, it has been revised several times, mainly for the purpose of international harmonization. Recently the Korean government stresses the importance of pro-patent policies, i.e., strengthening intellectual property right in order to stimulate business innovation and to regain international competitiveness. It is found that increases in patent application in the late 1990"s are attributed to a surge of IT patents, e-business method patenting were already more than an item of curiosity; this was particularly the case in terms of patent-eligibility of new technologies and pioneer attempts to craft claims and gain what their drafters hope will be valid patent protection. The focus today has shifted more toward the creation of a practical patent portfolio that will provide enforceable and marketable intellectual property rights. Recent and dramatic improvements in the patent enforcement regime in Korea have placed a global spotlight squarely on Seoul. Because of the continued comparative interest in patent-eligibility for new technologies, the opening portion of this paper treats the question of precisely which technologies are eligible for patent protection, assuming that what is claimed is both novel and nonobvious. A new level of consideration focuses more on the type of claims that will be enforceable, particularly with a focus on e-business methods. Finally, it matters little if claims are valid and enforceable, particularly if the wait for a decision extends beyond the cash burn life of a startup that so heavily relies on intellectual property protection. Parties with multinational interests in global intellectual property rights will now have to pay greater attention to their Korean rights. This paper assesses the impact of series of revisions of Korean patent system on firm"s innovation activities.
