Electromagnetic interference(EMI) shielding characteristics of composite filled with Cu flake and carbon brush powder as hybrid conductive filler and EAF slag have been studied. The coaxial transmission line method of ASTM D4935-99 was used to measure the EMI Shielding effectiveness of composites as formulation in frequency rage $100\~1,000MHz$ The SE also increases with the increase in flier loading. The hybrid filler filled composites show higher SE compared to that of only Cu flake. The correlation between SE and conductivity of the various composites is also discussed. The results indicate that the composites having higher filler loading$({\geq}40wt.\%)$ can be used for the purpose of safety materials to protect hazardous electromagnetic interference.

Artist-in-residence which gets chances to create by artists' moving and encountering new culture is heightening its level in 21th century. Under the circumstance that issue of cultural diversity and the role of artists which is for city revitalization and sustainability are affect residency program in the midst of highly proceeded globalization that international exchange. Therefore, in the aspect of creative city, a new model is creating by reuse of abandoned industrial facilities and Asia or Eastern country become the subject in residency program management, the issue of cultural diversity is getting more important, programs based on project not just residence are managing. Furthermore, it has inter-country cooperating system in the rage of cultural management. It means that artists' space of creating activity has a new, social role in spontaneously we need to approach to following model in Korea, as well.

본 논문은 CCD 카메라로부터 얻어진 차량 영상에서 번호판 영역이 일정한 패턴의 광강도를 지니는 특징을 이용하여 번호판 영역을 추출학 문자인식을 개선하기 위하여 단일 역전파 신경망 대신 다중 역전파 신경망으로 차량 번호판 인식 시스템을 구현하였다. 본 논문의 실험 결과, 효율적인 문자 영역의 추출이 가능하고, 기존의 단일 역전파 방법보다 학습 시간이 단축되고 인식율이 향상됨을 보인다.

The performance of two vertical-blade eliminators (V1, V2) and two horizontal-blade ones (H1, H2) for absorption chillers were tested in terms of pressure drop and refrigerant entrainment. The test was carried out using a wind tunnel with a cross section of 300 mm$\times$300 mm. The pressure drop of four eliminators tested was found to be in the rage of 1.0~2.7mm $H_2O$ at the face velocity of 2m/s. In the refrigerant entrainment test the vertical-blade eliminators showed much better performance than the horizontal-blade ones. The horizontal-blade eliminators showed satisfactory results at the air velocity of 2m/s but exceeded the limit value at 3 m/s. Since the cooling capacity of a machine is lowered by about 2.5% at the pressure drop of 1 m $H_2O$, more researches are required to reduce the pressure drop in the eliminator.

This research explored links between mother/child personality characteristics based on their diagnostic and clinical pathology. The 232 participants, selected from mother-child pairs receiving psychological care in a hospital setting, were tested and interviewed by clinical practitioners. Correlations were found between mothers' Psychopathic Deviate, Paranoia, Psychasthenia, and Schizophrenia and sons' Psychasthenia, aggression, alienation, depression, and anger. Mothers classified with Hysteria were likely to have aggressive children. Mothers with low self-esteem, repression, frustration, and strong levels of extroversion had daughters with anger/rage issues. Sons of mothers diagnosed with Hypochondriasis, Depression, Hysteria, Psychopathic Deviate, Paranoia, and Psychasthenia had high rates of Oppositional Defiant Disorder and ADHD. Children of mothers diagnosed with depression had high rates of ADHD. Specifically, mothers with Hypochondriasis, Hysteria, and Psychopathic Deviate had daughters with high rates of ADHD.

In this paper, we propose a pose estimation method using local map acquired from 2d laser range finder information. The proposed method uses extended kalman filter. The state equation is a navigation system equation of Nomad Super Scout II. The measurement equation is a map-based measurement equation using a SICK PLS 101-112 sensor. We describe a map consisting of geometric features such as plane, edge and corner. For pose estimation we scan external environments by laser rage finer. And then these data are fed to kalman filter to estimate robot pose and position. The proposed method enables very fast simultaneous map building and pose estimation.

This paper is the result of the study of diseases, treatments, and causes of death of Yunsan-Gun, King Jungjong, King Injong, and etc that are recorded in The Authentic Record of Chosun Dynasty. Yunsan-Gun died at the age of 31, two months after he was expelled to Kanghwa Island. His rage, regret and emotional disorder injured Wonki therefore, exopathogens easily affected and finally caused death. King Jungjong died of old age. King Injong was born with weak heart and stomach, and attack of sorrow among seven emotions, and failure of harmonious intake of food lead to death.

This paper is aiming at calculating NOx concentration, which is one of the harmhul components of emission from the gasoline engine, formed in the combustor through the presess of combustion. Instantaneous temperature and concentration of each components for each division can be determined by the solution of simulatneous equation of reaction equation and equation of energy conservation, inputting the estimated temperature with a considerably wide rage of temperature. After determining instantaneous temperature and instantanous concentration of each components, the nonequilibrium calculation is performed based on the reaction kinetics in order to determine NOx concentration. To summarize the result abtained from the above method ;through the passage of NO concentration, NO concentration is the highest in the first division and it is gradually decreasing through the following divisions In the final division, NO concentation is the lowest.

Hot shearing is a method of producing various high-quality planar machine parts by using reduced punch load. In order to predict the results of this process, the deformation behavior of work material at elevated temperatures need to be studied. In this research, a tensile test was carried out for 5052 aluminum alloy at high temperatures of $240-540^{\circ}C$ and strain rates of 0.001-0.1/s. The results of the tensile tests were studied to predict the deformation of the alloy during the hot shearing process. The results showed that hot shearing within a temperature range of $340-440^{\circ}C$ and a strain rate rage of 0.001-01/s will be the most effective in reducing punch load and increasing the sheared edge in the case of 5052 aluminum alloy.

We had prepared MLV liposome with Hibiscus Esculentus Ext.(HEE) which have fluorescent light in order to evaluate its percutaneous absorption about hairless rat skin. Then we investigated particle size of MLV using confocal laser scanning microscope(CLSM) and transmission electron microscope(TEM), respectively. Stability of MLV liposome and penetration of MLV liposome to hairless rat skin was measured by CLSM. As a result of experiments, MLV was globular shape and the rage of particle size was 0.3-0.5$\mu\textrm{m}$ mostly. Cream-type MLV had high stability comparatively. When we treated with MLV to rat skin, skin penetration was enhanced, especially, the optimum concentration of MLV on penetration to rat skin was 10%. Optimum penetration time was 6hr-12hr. And MLV-type HEE was more effective on percutaneous absorption than HEE-cream or liposome-type HEE.
