홍피증 환자 39명에 대한 임상 소견 및 원인 규명에 관한 연구
안세진,장경애,문기찬,성경제,최지호,고재경 대한피부과학회 1999 大韓皮膚科學會誌 Vol.37 No.5
Background: Erythroderma may result from different causes. Almost all the published original clinical series of erythroderma originated from western countries. Objectives: The objective was to evaluate various causes of erythroderma in our environment, frequency, clinical and laboratory findings, and patient evolution. Method: We reviewed the clinical and laboratory findings including biopsy materials of 39 patients diagnosed as erythroderma and treated during the last 9 years (from 1989 to 1998). Results: The male-female ratio was 3 to 1. The mean age at diagnosis was 54 years. Drug reaction and undetermined cause were the most frequent cause (30.8%, respectively), followed by the pre-existing dermatoses (28.2%), and malignancies (10.3%). Elevated erythrocyte sedimentation rate was found in 70.4% of the patients. Eight patients were resistant to treatment. In the patients with the persistent erythroderma, leukocytosis, elevated erythrocyte sedimentation rate, and cosinophilia were the common findings. Conclusions: Half of the patients with the erythroderma of undetermined cause showed the protracted course. Two patients diagnosed as cutaneous T-cell lymphoma and Se´zary syndrome had the history of generalized erythroderma of more than 3 years. The close follow-up for the erythroderma of undetermined cause with frequent laboratory and histopathological evaluations would be mandatory.

시장에서 시판되고 있는 장뇌삼을 재료로 하여 변조 특성 및 이들 변조삼의 진위여부를 판별하고자 그 특성을 조사하였다. 장뇌삼의 변조는 뇌두와 뿌리부위를 주로 변조하는 것으로 나타났다. 뇌두부위는 경흔적수와 수근수를 늘리던가 아니면 뇌두를 장뇌로 변조하였고 뿌리 부위는 지근수 및 지근장을 늘리는 것으로 나타났다. 변조한 뇌두부위의 특징은 먼저 뇌두하단에 있는 동체의 중심주를 요(凹)모양으로 만들고 변조한 뇌두를 철(凸)모양으로 깍아 심지 박듯이 맞추는 것이었다. 또한 각기 다른 인삼의 뇌두를 교묘히 잇대어 장뇌로 만들었고 여기에 수근을 접착하여 오래된 진짜 산삼 형태와 유사하게 변조하였다. 그리고 뿌리부위는 접착면을 절편 자르듯 사선으로 잘라 접착면이 많게 하였고 후에 이들 접착면을 비벼 흔적을 없애는 수법이었다. 변조에 사용된 재료는 인삼 및 출처불명의 약초뿌리를 사용하였고 접착제는 공업용으로 접착성이 강한 것을 사용하였다. For identification of altering methods and distinction of altered long-rhizome ginseng, we studied the properties of long-rhizome ginseng which is being sold in market. Artificial long-rhizome ginsengs were made by modification of rhizomes and roots. Artificial long rhizomes were made by increasing the number of stem vestige root and rhizome root or by modification of rhizome to long-rhizome. Roots were modified by increasing of the number and the length of secondary roots. Artificial long rhizomes were made by carving the rhizome in concave shape and attaching convex shaped modified another rhizome. Those who make artificial ginseng made the altered long-rhizome ginseng looks like real long-aged wild ginseng by elongation of the rhizome by attaching many ginseng rhizomes and attaching of secondary roots. They cut the attaching surface obliquely for increased number of attaching point and removed the vestige by scrubbing the attaching region. They used ginseng, medicinal plant from doubtful origin, and industrial strong adhesives for making altered long-rhizome ginseng.

Mobile nodes in ad hoc mobile networks typically communicate over wireless channels and are capable of movement. These are networks that support multihop communication and can be formed on a temporary basis. This paper proposes a solution that allows mobile nodes to access the wired Internet and to roam from base station to base station. And we also develop the efficient method that adapts in Global MANET which can be changed over time. It is observed that we can reduce not only error detection time but also network load, thus increasing the data reception rate in Global MANET Environment.
Dual-curable fluorinated poly(methacrylate) copolymers for optical adhesives
Jang, Se-Chan,Yi, Sung-Chul,Kim, Yang-Bae,Hong, Jin-Who John Wiley Sons, Ltd. 2005 Polymers for advanced technologies Vol.16 No.6
<P>In pursuit of photo-curable adhesive for optical communication, dual-curable acrylic oligomers (AOs) having alkoxy silane group, fluorine atoms and vinyl group as a pendent group were synthesized by two-stage reactions. The isocyanate group containing oligomers were firstly synthesized via radical polymerization of acrylic monomers, and followed by urethane reaction with 2-hydroxy ethyl methacrylate. The dual curing behaviors, e.g. thermal and photo-cure, were studied by using photo-differential scanning calorimetry (DSC) and real-time IR. An optimum adhesive formulation, based on AO (15 g), epoxy acrylate (80 g), isobonyl methacrylate (17 g) and photo-initiator (3 g), was obtained. As the content of AO was increased in the optical adhesive formulation, refractive index decreased but transmittance increased due to the increase in fluorine content. The optical transmittance at the range of 1.3 to 1.55 μm was higher than 90%. The addition of colloidal silica with the earlier mentioned formulation was helpful in decreasing crosslinking volume shrinkage and the increasing of glass fiber adhesion. The required properties for the optical adhesive, including chemical resistance and thermal resistance, dimension stability, etc. were also investigated. Copyright © 2005 John Wiley & Sons, Ltd.</P>
The Pattern of Cognitive Warfare in Modern Battles and Conflicts

Cognitive warfare, also known as fifth generation warfare, is considered a crucial factor in achieving victory in modern battles and conflicts. Authoritarian State such as the N.Korea, Russia, and China have identified the cognitive domain as the sixth domain, following land, maritime, air, space, and cyber/electromagnetic domains. These countries are actively seeking to gain an advantage in the cognitive domain through the use of social media and dissemination of false information. In light of this, we will analyze the cognitive warfare tactics employed in the 2020 Armenia-Azerbaijan War and the 2021 Israel-Palestine Conflict, define the concept of cognitive warfare for our military, and propose strategies for both conducting and responding to cognitive warfare.
How Cognitive Warfare Developed in the India-Pakistan War and the Ukraine-Russia War

Cognitive warfare is an aspect of warfare that attempts to achieve strategic objectives by influencing human perception. In the Kargil War, India used cognitive warfare to inform the international community, including the United States, that Pakistan was supporting terrorist organizations and had illegally invaded Indian territory. Ukraine is using bilingual English and Ukrainian social media accounts to communicate with the Ukrainian people and the international community, from the president down to troops in the field. Ukraine is also building trust by posting pictures and reports from the battlefield at set times each day to counter Russian fake news. The study draws implications by comparing and contrasting India's cognitive war against Pakistan in the 1999 Kargil War with Ukraine's cognitive war against Russia in 2022, nearly 30 years later.

This paper discusses an information architecture for integrated management of ship information. To manage various devices of lower layer and applications of upper layer, we have introduced data structure based on the NMEA 2000 and IEC 61162-4. An introduced information architecture will be effectively applied to implement e-Navigation.
