Nephrogenic fibrosing dermopathy (NFD) is a rare cutaneous fibrosing disorder that primarily affects patients with a history of renal disease. NFD manifests with induration, thickening and hardening of the skin with brawny hyperpigmentation. Lesions are typically symmetrical and usually develop on the limbs and trunk. Flexion contractures of the joints may be a feature of the disease. Histopathological features of NFD include proliferation of dermal fibroblasts and dendritic cells, thickened collagen bundles, increased elastic fibers and focal mucin deposition. Although the pathogenesis remains largely unknown, some of the factors implicated in the pathogenesis include renal dysfunction, circulating fibrocytes, vascular injury, and gadolinium which is a contrast material used in magnetic resonance imaging. Currently, no definitive or uniformly effective therapies are available for the treatment of NFD. We herein describe the case of a 44-year-old female NFD patient who undergoes significant improvement of skin lesions and associated joint contracture after renal transplantation.

Background: The O-Z flap is a kind of rotational flap that consists of a combination of two opposing rotation flaps. The double O-Z flap is a variant of the O-Z flap applied in multiple adjacent surgical defects that can simplify closure by combining closure into one technique. Objective: To report our experience with the O-Z flap and double O-Z flap in the reconstruction of surgical defects of the face after Mohs` micrographic surgery (MMS), using postoperative clinical and cosmetic results. Methods: Sixteen patients diagnosed with non malignant melanoma skin cancer on the face were treated with MMS. The resultant surgical defects were reconstructed with an O-Z flap in 14 patients and with a double O-Z flap in 2 patients. Clinical outcomes were reviewed, and cosmetic results were scored as excellent, good, fair, poor, or very poor. Results: In the 14 patients using O-Z flap, 6 cases were located on the temple, 4 on the forehead, 2 on the cheek, and 1 of each on the nose and philtrum. Of the two patients using double O-Z flap, one had two adjacent basal cell carcinomas on the cheek, and the other had two adjacent squamous cell carcinomas on the forehead. The size of the primary defects ranged from 1.1 to 2.5 cm in greatest diameter (mean, 1.93 cm). There were no significant local complications. There was no tumor recurrence, and 14 of 16 patients showed satisfactory aesthetic outcomes scored as excellent or good. Conclusion: O-Z flap reconstruction was effective for the closure of surgical defects with limited skin laxity in the face. The double O-Z flap is ideally suited to combine closure of adjacent surgical defects into one technique without exerting undue tension or distorting the surrounding structures. We found these flaps were simple to construct and provided aesthetically pleasing results. Therefore, they could be useful reconstructive options in facial skin defects after MMS.

Surgical anatomy of head and neck

Regardless of beginners and experts, dermatologic surgeons should be well aware of surgical anatomy. Especially, because head and neck areas is closely related to procedures for not only cosmesis but also dermatologic oncology, the thorough knowledge of surgical anatomy of these areas is essential for us. In head and neck area, functionally and cosmetically important structures like eyes, nose and lips are concentrated in relatively small area, and there are several significant variations in the skin of respective anatomic subunits. Also, the relationship to underlying structures like adipose tissue, muscle, cartilage and bone as well as skin of head and neck has distinct features. Therefore, in this lecture, I would like to discuss the fundamental surgical anatomy of head and neck needed for beginners to perform dermatologic procedures.

Korean government`s support for biotechnology field began in early 1980`s. The main aim was economic growth through the application of biotechnology. Ministry of Science and Technology included genetic engineering as one prominent field in the Development Plan for Economy and Society(1982-1986), and National Assembly established Genetic Engineering Support Act in 1983. Ten years later, the overall ministries started to promote biotechnology in the name of Biotech 2000, and the main aim was still economic growth. But the substantive contents of Biotech 2000 were some distance from the aim of it, and all the more became weak in comparison with the situation in early 1980`s. This article showed that the scientists who were involved in the process of biotechnology policy formation had a decisive effect to the trend of governmental strategy. At first the scientists chose the genetic engineering field intentionally for persuading governmental officials to be worth money. Afterwards they tried to change the name of the field from genetic engineering to biotechnology because they wanted to be supported more broadly. There was some disagreement about the range of support within scientists group when they acted to make the Act. This led the uncommon definition of the field "genetic engineering" through a compromise among scientists. This study would help to understand the characteristics of early biotechnology field in Korea, and suggest the necessity of examining how much the opinion of scientists group has influenced the governmental policy until recently.

도립진자 시스템에서 칼만 필터링 최적의 결과를 얻기 위해서는 잡음 공분산 행열 Q, 측정잡음 공분산 행열 R과 초기 에러 공분산 행열 P<sub>0</sub>와 같은 인자가 필요하다. 이러한 인자는 실제 상황에서 근사화된 값을 사용하거나 정확한 값을 알 수 없기 때문에 칼만 필터의 최적화에 영향을 미치지 않거나 이러한 공분산 행열의 스칼라 이득변화에 덜 민감한 경우를 연구의 대상으로 하고 있다. 또한 상태 측정시 에러를 예측하는 방법으로 구해진 에러 공분산 행열은 상태측정 값 보다는 공분산 행열의 이득과 연관성을 가지게 된다. 따라서 3가지 공분산 행열과 칼만 이득 그리고 에러 공분산 행열 간의 상관관계가 잡음인자인 스칼라 이득과의 연관성을 해석하고자 하였다. 본 연구는 3절에서 도립진자 시스템 모델을 간략하게 정리를 하였고 4절에서는 이러한 모델을 기반으로 하여 컴퓨터 시뮬레이션을 위한 도립진자 시스템에 대한 수학적 동적모델을 구성하고 5절에서는 이러한 인자와 스칼라 이득 값을 이용한 다양한 시뮬레이션 결과를 통하여 잡음인자의 연관성을 해석하였다. The Optimal results of Kalman Filtering on the Inverted Pendulum System requires an effective factor such as the noise covariance matrix Q, the measurement noise covariance matrix R and the initial error covariance matrix P<sub>0</sub>. We present a special case where the optimality of the filter is not destroyed and not sensitive to scaling of these covariance matrix because these factors are unknown or are known only approximately in the practical situation. Moreover, the error covariance matrices issued by this method predict errors in the state estimate consistent with the scaled covariance matrices and not the issued state estimates. Various results using the scalar gain δ are derived to described the relations among the three covariance matrices, Kalman Gain and the error covariance matrices. This paper is described as follows: Section III a brief overview of the Inverted Pendulum system. Section IV deals with the mathematical dynamic model of the system used for the computer simulation. Section V presents a various simulation results using the scalar gain.
