This study aims to summarize the history of German-speaking urban morphology with focus on the establishment stage of that. Now two stages are identified as followings. The first is emerging stage of urban morphology. At this stage. O. Schluter insisted the concept of urban form : Urban form is the clue of reading the urban history and the development stage, And he introduced urban plan(Stadtplan) to Human Geography as a research object. H. Hassinger was interested in the preservation of historical buildings in Wien, and studied about the style of buildings. The elements of Stadtplan are identified as square, street and block by E. J. Siedler. A. E. Brinckmann regarded urban form as a great sculpture in the art-historical point of view. Urban form, at first stage, was described spatially and synchronically on the base of Stadtplan and building types as the research objects. And the second is the establishment stage of research objects, concept and methods. W. Geisler divided urban form into three level : site-Stadtplan-building. R. Martiny studied about 60 German cities and made the typological approach based upon the street network and settlement form. But H. Bobek criticized pure spatial and synchronic approach and made chronological one about lnnsbruck. He was interested in the change of urban form, and thought economic factor very important as agents of the change of urban form. He introduced urban land use to research of change of urban form as research objects(as economic entity in urban form). Untill this stage, most of research methods, objects and concepts are introduced, though immature. So this stage is called the establishment stage for this reason. Through comparing German-speaking urban morphology with Korean one, we can define the status of ours and this study can help us to make orientation of following studies.

방사선근접치료 분야의 선량 측정을 위해 제조된 Lead(Ⅱ) Iodide 선량계의 적용가능성 연구

양승우(Seung-Woo Yang),한무재(Moo-Jae Han),박성광(Sung-Kwang Park) 한국방사선학회 2021 한국방사선학회 논문지 Vol.15 No.6

근접방사선치료는 방사선동위원소를 신체 내부에 넣어 종양에 방사선을 집중적으로 조사하는 치료법이다. 근접방사선 치료는 고선량율의 방사선동위원소 선원을 사용하기 때문에 정확한 선원의 위치 및 선량등을 파악하는 것이 매우 중요하다. 하지만 임상에서는 ruler, autoradiograph등을 통하여 육안으로 부정확하게 평가하는 실정이다. 이에 본 연구에서는 Lead(Ⅱ) Iodide(PbI2) 물질을 사용하여 방사선근접치료에 사용할 수 있는 선량계를 개발하고, 재현성, 선형성, PID 항목을 분석하여 적용가능성을 평가하였다. 재현성 평가결과, RSD 값은 1.41%로 평가기준 1.5%를 만족하였다. 선형성 평가결과, R2값은 0.9993으로 평가기준 0.9990을 만족하였다. PID 평가 결과 50% 선량 감약지점에서 거리의 역자승 법칙의 이론값과 비교하여 0.06 cm의 차이만을 나타내었다. 본 실험에서 제작된 선량계는 모든 평가에서 기준치를 만족하는 결과값을 나타내어 방사선근접치료 영역에서의 선량계 적용 가능성이 충분한 것으로 판단된다. Brachytherapy is a treatment in which radioactive isotopes are placed inside the body to intensively irradiate the tumor with radiation. Because brachytherapy uses a radioisotope source with a high dose rate, it is very important to know the exact location and dose of the source. However, in clinical practice, it is evaluated inaccurately with the naked eye through rulers and autoradiographs. Therefore, in this study, a dosimeter that can be used for brachytherapy was developed using a lead(II) iodide (PbI2) material, and the applicability was evaluated by analyzing the reproducibility, linearity, and PID items. As a result of reproducibility evaluation, the RSD value was 1.41%, satisfying the evaluation criteria of 1.5%. As a result of the linearity evaluation, the R2 value was 0.9993, which satisfies the evaluation criterion of 0.9990. As a result of PID evaluation, it showed only a difference of 0.06 cm compared with the theoretical value of the inverse square law of distance at the 50% dose reduction point. The dosimeter manufactured in this experiment shows results that satisfy the standard in all evaluations, so it is judged that the possibility of applying the dosimeter in the radiation brachytherapy area is sufficient.

영업비밀의 쟁점 및 효과적 보호방안에 대한 검토

  During the past years, a number of trade secrets infringement cases have drawn considerable media attention as they involved illegal disclosure of valuable technology owned by some of the major Korean corporations. With the rapid growth of the information and technology industry in Korea, there is a growing awareness of the significance of trade secrets as valuable corporate property among the companies and individuals investing heavily in the research and development of state-of-the-art technologies.<BR>  Notwithstanding the importance of trade secrets, however, Korean law had traditionally been scarcely protective of trade secrets of companies. It is only recently, in the wake of several major trade secret infringement cases in Korea, that the Korean government began to take some meaningful steps to strengthen its legal regime for the protection of trade secrets. Specifically, in 2004, the Korean government amended the Trade Secret Protection Act to further strengthen the protection of trade secrets.<BR>  Protection of trade secrets is important in the sense that once trade secrets are disclosed to a third party, they experience a substantial loss in their economic utility due to their confidential nature. Furthermore, the loss of economic utility is a serious blow to the enterprise that owns trade secrets as it materially damages the competitiveness of such enterprise in the market.<BR>  Based on experience of representing numerous corporations in trade secret infringement disputes, we would advise the owners of trade secrets to consider taking the following measures in order to protect their trade secrets from illegal disclosure or use:<BR>  In case a licensor enters into a license agreement with a prospective licensee concerning a technology that is prone to illegal disclosure, the licensor should consider inserting a non-disclosure provision in the license agreement which would prohibit the licensee from unauthorized disclosure of the trade secrets transferred to the licensee under the license agreement. In this regard, it should be noted that questions may arise under Korean law concerning the issue of whether if the non-disclosure obligation has a specific term, the licensee, after the expiration of such term, is entitled to actively disclose the trade secrets to a third party without payment of any royalties to the licensor. In practice, there have been instances where licensees have engaged in freely using the trade secrets or even licensing the trade secrets to a third party after the expiration of the term of the non-disclosure obligation.<BR>  To prevent any illegal disclosure of trade secrets internally by officers or employees, an enterprise may set up employment regulations or require a written undertaking from new or resigning officers or employees to the effect that such officers or employees shall not illegally disclose or use the trade secrets of the enterprise during or after the term of their employment. Additionally, it is also possible for the enterprise to prohibit its officers or employees from being employed by any competitors of the enterprise or from competing with the enterprise themselves for a specific term after the term of their employment. In this regard, it is important to note that the term of such non-compete restriction should be a reasonable one, as an unreasonably lengthy term of a non-compete restriction could be deemed as an unreasonable usurpation on such officer"s or employee"s freedom to choose an occupation under the Korean Constitution and thus, deemed unenforceable.<BR>  An enterprise that owns trade secrets is recommended to establish and operate trade secret management rules. Moreover, the enterprise should consider designating a person responsible for protection of trade secrets of the enterprise and clearly defining the scope of his responsibilities. It is also helpful to provide regu

방사선 치료 영역에서 전자선은 표재성 병변 치료에 자주 쓰인다. 전자선은 빔 경로에 것들과 상호 작용하여 선량측정에 영향을 끼치기에 정확한 측정이 요구된다. 하지만 전자선 정도관리에 관한 연구는 이루어 지고 있지 않는 실정이다. 이에 본 연구에서는 전자선 정도관리를 위한 기초연구로 PbO 기반의 선량계를 제작하였다. 그리고 6, 9, 12 MeV 에너지에 따른 재현성, 선형성을 분석하여 계측정확성과 정밀성을 평가하였다. 재현성 측정결과 6, 9, 12 MeV에서 각각 1.024%, 1.019%, 0.890%의 RSD 값으로 나타났다. 그리고 선형선 측정결과에서는 6, 9, 12 MeV에서 모두 0.9999 R2로 나타났다. 두 평가 모두 우수한 결과로 PbO 선량계의 계측정확성과 정밀성이 매우 우수한 것으로 나타났다. In radiation therapy, electron beam is often used in the treatment of superficial lesion. Accurate measurements are required because electron beam interacts with them in the beam path and affects dose measurements. However, no research has been conducted on electron beam quality assurance. in this study, PbO-based dosimeter was fabricated as a basic study for electron beam quality assurance. Thus, the reproducibility and linearity of the energy of 6, 9, and 12 MeV were analyzed to evaluate measurement accuracy and precision. Reproducibility measurements show RSD value of 1.024%, 1.019% and 0.890%, respectively, at 6, 9, and 12 MeV. linearity measurements show 0.9999 R2 at 6, 9, and 12 MeV altogether. Both evaluations show that the PbO dosimeter has very good measurement accuracy and precision with excellent results.

마이크로스트립 구조 해석을 위한 Closed-Form 그린 함수

양승우(Seung-Woo Yang),김성진(Sung-Jin Kim),김건우(Gun-Woo Kim),이택경(Taek-Kyung Lee) 한국전자파학회 2008 한국전자파학회논문지 Vol.19 No.3

평면형 구조에서 공간 영역 그린 함수를 구하기 위해서는 무한 Sommerfeld 적분을 계산하여야 한다. 무한적분을 짧은 시간에 계산하기 위한 실수축 적분 방법(real axis integration method)은 주파수와 거리에 대해 넓은 범위에 걸쳐 매우 정확한 방법이지만 관측점의 수직 성분 z가 변하게 되면, 근사의 과정을 반복해야 하는 비효율성과 z가 커질수록 파수 영역 함수의 변화가 심해져 정확한 근사가 어렵다는 단점이 있다. 본 논문에서는 폐루프 적분 경로를 이용하여 파수 영역 함수를 근사화 함으로써 일반적인 마이크로스트립 구조에서 기존의 결과에 비해 정확한 closed-form 그린 함수를 구하는 방법을 제시하였다. In the layered medium, the Sommerfeld integral must be evaluated to calculate a space domain Green's function. The real axis integration method provides stable and accurate results over wide ranges of the observation distance and the singnal frequency. But this method has the inefficiency of approximation when the field point z is changed. Also, as the amplitude of z increases, the change of the spectral domain function is more rapidly. Therefore, the approximation is difficult when z becomes larger. In this paper, we propose a method to calculate an accurate closed-form Green's function for microstrip structure by using the closed-loop integration path.
