2011년도 Nobel 생리(生理) 의학상(醫學賞) : 자연(自然)(선천)(先天) 면역(免疫)(innate immunity)의 활성화에 관한 연구업적으로 B. A. Beutler와 J. A. Hoffmann, 그리고 수지상세포(樹枝狀細胞)(dendritic cell; DC)발견과 적응(適應)(획득)(獲得)면역(免疫)(adaptive immunity)에 있어서의 그들 세포의 역할을 밝혀낸 R. M. Steinman의 공동수상으로 금년도 Nobel 생리 의학상 수상자가 결정되었다는 보도가 지난 10월 3일 있었다(1-3). 그들의 업적을 요약하면 대략 다음과 같다. (Steinman교수는 Nobel수상자 발표 3일전인 9월 30일 암으로 사망함). 그들은 면역기구(immune system)의 활성화의 관건(key)이 되는 원리를 밝혀냄으로써, 면역기구에 관한 우리들의 이해를 혁신하였던 것이다. 과학자들은 오랫동안 세균(bacteria)이나 기타 미생물병원체들에 의한 공격에 대비하여 그들 자신을 방어하는 사람이나 기타 동물체에서의 면역응답(免疫應答)(immune response)의 문지기들을 탐색해 왔다. Beutler와 Hoffmann은 그와 같은 병원미생물을 인식하여 생체의 면역응답의 첫 단계인 자연면역을 활성화 할 수 있는 수용체 단백질(toll-like receptor protein)을 규명한 것이다(4,5). 한편 Steinmann은 면역계의 수지상세포(DC)와 병원미생물이 생체로부터 배제되는 면역응답의 후기단계인 적응면역을 활성화하고 조절하는 그들의 독특한 재능을 규명해 낸 것이다(6-8). 그들 3명의 발명은, 면역응답의 자연 및 적응 양상(樣相)이 어떻게 활성화되는 가를 밝혀냄으로써 질병의 기전에 관한 참신한 식견(識見)을 제공한 것이다. 그들의 연구는 감염병(感染病)(infectious disease), 암(癌)(cancer) 그리고 염증성질환(炎症性疾患)(inflammatory disease)에 대응하는 예방과 치료의 개발을 위한 새로운 방법을 개척한 것이다.

We herein analyze the survivability of an airborne platform when an active decoy delivers jamming attacks against an active RF seeker system that operates based on the proportional navigation guidance law. In encounter scenarios with various conditions, such as platform maneuvering, the decoy's RF specification, and the seeker's approaching range and angles, the missed distance of the RF seeker is evaluated. By comparing the missed distance with the proximity of the fuze range, the platform's survivability is determined and the survival area of the platform is drawn on several encounter scenarios.

Marine accidents are increasing year by year, and various accidents occur such as engine failure, collision, stranding, and fire. These marine accidents present a risk of large casualties. It is important to prevent accidents beforehand. In this study, we propose a modeling to predict the occurrence of marine accidents by applying the Markov Chain Process that can predict the future based on past data. Applying the proposed modeling, the probability of future marine accidents was calculated and compared with the actual frequency. Through this, a probabilistic model was proposed to prepare a prediction system for marine accidents, and it is expected to contribute to predicting various marine accidents.

In this paper, we proposed vertically structured radiator for increasing bandwidth and gain of mobile phone internal antenna. The proposed antenna has vertically structured radiator instead of planar structured radiator to improve the antenna characteristics for GSM850/900 and DCS1800/PCS1900 bands. The antenna improve bandwidth of low band with 28 % than planar structured radiator. and also, improve bandwidth of high band with 14 %, efficiency 31.80~86.36 %, average gain -4.956~-0.617 dBi on the GSM850/900 and DCS1800/PCS1900 bands. These results are good performance among the small antenna with vertically structured radiator for increasing bandwidth and gain.

A simple and rapid method, based on separation of a flying oil into monomeric, dimeric and oligomeric triglyceride by means of high performance size exclusion chromatography on Ultrastyragel column (500 A), is proposed for evaluation of the quality of used frying oil. The relative area of the monomeric triglyceride was decreased with frying time increase, however, the decrease rate was significantly reduced by treatment of a composited powder (porous rhyorite/citric acid 40/56/4). This measurement showed good linear relationship with change in polar component measurement. There were no significant differences between the slopes of regression lines in both treated and non-treated frying oil system for relationship between monomeric triglyceride and polar component. By this method, it was found that a frying oil habe to be discarded if the content monomeric triglyceride decreased to 71%, which was corresponed to 27% polar component.

This paper investigates the effects of diffuser on the acoustical parameters in music hall with consideration of the result of scattering coefficient measurement. A scale model hall of 600 seats with orchestra shell was used for experiments. The materials of 1:50 scale model was chosen through absorption coefficient measurement based on ISO 354. The model was matched to the computer simulation model in terms of reverberation time. In order to evaluate the effect of diffuser location, the measurements were accomplished with and without diffusers according to 7 configurations by diffuser-installed region; sidewall, balcony front, ceiling and so on. The following acoustical parameters were extracted from each measurement case; Reverberation time (RT), Early decay time (EDT), Clarity (C80), Center time (Ts), Sound strength (G) and Temporal diffusion (TD) from the auto-correlation function (ACF) of impulse responses. As a result, the absorption power and diffusion power were increased with number of diffusers. Accordingly RT, EDT and G were decreased by diffuser and the redirection of reflections was occurred briskly. Averaged TD was 6.05 to 6.30 by measurement cases. RT was found to be the most related factor to diffusion power (R = 0.94). The correlation between TD and EDT was high (R = 0.73). In addition, the effects of diffuser-installed location were discussed in terms of acoustical parameter variation.

Welfare desire has been diversified according to the increase of economic level and rapid social change. The desire for comprehensive service on culture, medical, mental and information level has appeared. Accordingly, it is necessary to establish an integrated community mixed-support facility, a space of accepting administration, welfare, leisure, culture and informatization request in a small local community in the future. The community mixed-support facility is a meeting place of local resident for information change, various basic service and ultimately for activation of community in order to contribute to regeneration and activation of existing urban core. Thus, this study figured out general status of community mixed-support facility and physical mixed type and analyzed spatial characteristics. Current community mixed-support facility has insufficient program and space to participate in by local residents and to accommodate mixed function. The future planned community mixed-support facility must secure multiple opportunities for various types of life by returning time and cost to user through the introduction of creative mixed concept. While reflecting unique local characteristics, and considering diversity of users, it needs to make mixed facility to cope with social changes. This study is limited in that the study reached a conclusion by survey and analysis only. However, it is expected that the result can be used as basic research data for the planning of community mixed-support facility to cope with living conditions of local residents or realistic requirements.

In this study, the possibility of seismic performance design was proposed and the quality verification test method was reviewed as part of the design of waterproof performance in underground walls under accelerated environment conditions for waterproofing materials, which are barrier and finishing material that can prevent ingress or overflowing water from inside and outside of a building by attaching all of the construction materials used in construction structures. Considering the current state of earthquake-resistant design of construction materials in Korea and abroad, seismic product groups are rare and mostly dependent on construction methods because there are no regulations on materials, although there are still regulations on earthquake-resistant design in the building process under the current law. Overseas, it was possible to confirm that various building materials that gave seismic performance to non-structural materials, such as Japan, Canada, and Germany, are being developed. If it is possible to have a complementary response to earthquakes in the advanced external waterproofing materials, it can be expected to be applicable as leak prevention and prevention technology along with the seismic designed structure.
