Intramolecular energy migration in a cyclic porphyrin array is spontaneous transfer of energy from one excited site to another. Since the efficiency of energy migration is inversely proportional to distance, the energy migration is occurred on their adjacent sites more often than distant ones. Therefore, the energy migration in the cyclic porphyrin array is largely dependent on their conformational characters. However, evaluation of conformational information by means of experimental tools is ambiguous since their limited resolution. In this work, we calculate the internal angle and distance distributions of cyclic porphyrin arrays using molecular dynamics simulations to obtain conformational information. To evaluate the angle and distance distributions respect to molecular size, we constructed molecules with n porphyrin dimers (n=1,3,7) in implicit solvent environment. Performing molecular dynamics simulations, we modulated alkyl groups to investigate additional conformational effects of the system.

The purpose of this study was to develop generalized validity evaluation indexes for the Sasang type diagnostic test. As a generalized evaluation index for Sasang type diagnostic test, Generalized Squared Correlation (GC2), Mutual Information (I) and Mutual Information Coefficient (IC) as overall validity index, and Correlation Coefficient (C) and Mutual Information Contribution (ID) as type-specific validity index were suggested and the practicability of these indexes was assessed along with Percentage Correctly Predicted (PCP), adjusted PCP, type-specific sensitivity and type-specific specificity which was proposed previously. The usefulness of the nine validity indexes was examined using previously reported data and three mock Sasang type diagnosis results. We demonstrated here that the PCP is not adequate for the analysis of validity. We also showed that our validity index is recommendable for the comparison and improvement of Sasang type diagnosis. The generalized validity analysis of Sasang type diagnosis can provide a guideline for the development of new Sasang type diagnosis or pattern identification. The working sheet for calculating validity indexes can be acquired at http://www.sasangtypology.org/validity.

The present condition of study on the wave-resonance for the bio-KI is observed. And the probroms of reception attendent on the stimulation of wave is observed centering around the sensory organ. The results is as follows: In the wave-resonant stand point, the tendency of studying on KI is showed in the several field all over the world. Because it is originated radionics, the wave-resonant tools of MRA insistenting minute-magnetism-resonance-apparatus need the more severe data in the side of electric circuit. The wave resonance apparatus according to the frequency occurance transmits low-frequency's vibration ratio to the electric stimulating aspect. The wave-water is considered on the application of wave-resonance transcription on the water, and needs the comprehension of torsion-field level. The wave-stimulation of the bio-KI and the reception of the sensory-organ is observed the connection of the sensory-organ and it's corresponding wave. The informations recorded in the wave are distinguished patternly. And the several shaping waves transmit the informations each other through the resonnance. The wave theory is explained the LEE(理) as the wave-pattern and the KI(氣) as the revelation of the patterned-wave in the LEE-KI theory(理氣論), moreover the SHIN(神) as the information of the wave-pattern and the KI as the energy of the wave and the JEUNG(精) as the material of the wave in the JEUNG-KI-SHIN theory(精氣神論). In this point, the study on the wave-resonance of bio-KI is thought that it is significantly in the study method for oriental medicine. The sum of the wave makes the moving body and forms the universe. It means that the several wave patterns gather and form new field. The pattern is a kind of the information and the information is not materially. The information of wave-pattern is the arrangement and the combination of the material source.

To realize river restoration that ecological characteristics of the river are reflected, we classified the river into four reaches of valley stream, upstream, midstream, and downstream based on substrate as well as riverbed gradient obtained from the relationship between distance from the river mouth, and above sea level. Considering that the rivers of Korea have been dominated by various and intense artificial interferences over a lengthy period, we determined cross sectional range of the river based on the geological map and clarified transformation degree by reach. Vegetation profile diagram was prepared by depicting horizontal range and vertical stratification of major vegetation appearing in a belt transect of 10 m breadth installed between weirs constructed in both sides of the river. Restoration models by river reach were prepared based on breadth of waterway, bare ground, herb, shrub, and tree dominated vegetation zones on vegetation profiles wherein a flooding regime was reflected. Species composition information collected from vegetation established in each zone was systematized to use for restoring each reach ecologically. Further, background that longitudinal reaches and horizontal zones were divided, was discussed by comparing with case studies in foreign countries. In addition, necessity of ecological restoration of the river was discussed based on degree of integrity of Korean rivers, ecological significance of riparian vegetation, and importance of reference information for ecological restoration of the river.

Purpose : The purpose of this study is to find out if it helps to improve static balance ability and weight bearing rate for chronic stroke patients with poor balance in clinical intervention through a method of correcting movement errors while performing a task by vibrotactile bio-feedback providing pressure information. Methods : Fifteen chronic stroke patients (12 male and 3 female) were participated in this study. To examine the effects of vibrotactile bio-feedback and general standing without bio-feedback on static balance ability and weight distribution symmetric index in all subjects randomized with R Studio. The static balance ability and weight distribution symmetric index of the participants was evaluated using a force plate. A paired t-test was used for comparison of each conditions. Statistical significance was set at α=0.05. Results : The comparisons of static balance ability and weight distribution symmetric index in chronic stroke patients after two different condition are as follows. In the static balance ability and weight distribution symmetric index, the vibrotactile feedback providing pressure information showed a significant difference compared to none feedback (p<.001). Conclusion : The vibrotactile bio-feedback providing pressure information in real time can support an improve in static balance ability, uniform weight bearing rehabilitation in chronic stroke patients. In the future, it is hoped that a follow-up study that provides a better direction of intervention compared to various feedback interventions commonly used in clinical practice.

본 논문은 기존의 소프트웨어가 멀티코어기반의 모바일 디바이스를 인지할 수 있도록 태스크 병렬화 시스템(BioMP)을 제안한다. 애플리케이션 개발자가 기존의 소프트웨어에 병렬화 규약의 코드를 추가하였을 때, 제안 시스템은 호환성 뿐만 아니라 병렬 쓰레드의 수행을 지원한다. BioMP는 기존의 대용량 애플리케이션 소스코드를 단시일에 멀티코어를 인지하는 소프트웨어로 개선한다. 실험 결과, 우리의 아이디어는 쿼드 코어기반의 멀티코어 환경에서 기존의 시스템 대비 애플리케이션 실행속도를 약 64%까지 개선하였다. 또한, BioMP는 독립적인 컴포넌트이기 때문에 어떠한 플랫폼의 추가적인 수정도 필요로 하지 않는다. 그 결과, 애플리케이션 개발자는 멀티코어향 소프트웨어를 애플리케이션 스토어에 배포하였을 때, 사용자는 모바일 디바이스의 어떠한 수정도 없이 즉시 실행을 할 수 있다.

의료 기술이나 관련 장비가 발달해온 것과 달리, 현재의 단체 건강검진 환경에는 여러 가지 비효율적 요소들이 존재한다. 이에 따라 본 논문에서는 단체 건강검진 현장의 개선을 위한 전자태그(RFID) 기반 운영관리 시스템을 제안하고자 한다. 본 시스템은 데이터베이스를 이용하여 검진과정에서 수집되는 데이터들을 실시간으로 관리하고, 이를 토대로 현장 검진의들의 작업을 지원할 수 있는 정보를 제공한다. 아울러, 수검자들은 검진현장을 순회할 때 기존처럼 문서로 된 검진서식을 지참하는 것이 아니라 개인 RFID 카드를 이용하게 되고, 수검자들의 검진 내역 역시 지속적으로 추적이 가능하다. 결과적으로 제안하는 시스템을 통하여 전체 검진현장의 실시간 통합 관리가 가능하며, 단체 건강검진 현장의 업무효율성과 수검자 편의성이 증진될 수 있다. 아울러, 제안하는 시스템은 건강검진 현장에서 여러 가지 성과지표를 수집, 산출하여 검진 서비스의 지속적인 개선을 위한 토대를 제공한다.
