The present study aims to explore the effects of applying spheroid-combined stimulating therapy on body composition. For this aim. 20 persons were selected as subjects and 10 of them each were assigned to the experimental group and control group, respectively. The experimental group was applied a 12-week combined stimulating therapy and changes in physical constitution of the members were measured before application and 4, 8 and 12 weeks after application. From the study, following conclusions could be drawn: First, body weights of the experimental group decreased from 59.9kgs before application of the spheroid-combined stimulating therapy to 57.2kgs 12 weeks after application, no significant but 4.51% change. Second, body fats of the experimental group changed from 18.8kgs before application to 16.4kgs 12 weeks after application, no significant but 12.77% reduction. Third, % fats of the experimental group decreased from 31.2% before application to 28.6% 12 weeks after application, no significant change but 8.33% reduction. Fourth, body mass index(BMI) of the experimental group decreased from 23.23 kg/㎡ before application of the therapy to 21.43kg/㎡ after application, no significant but 8.03% reduction. As seen above, the 12-week application of the spheroid-combined stimulating therapy produced no significant changes in physical constitution as physical exercise did, but improved physical constitution by reducing certain amount of boy weight, body fat, % fat and BMI. In order to detect more positive and significant changes in physical constitutions, continued studies and clinical experiments should be performed to more diverse subjects using technically reinforced equipment for spheroid-combined stimulating therapy.

Diagnosis or measurements using Infrared thermo-image hasn't been available. A quick diagnosis and thermal analysis can be possible when that kind of system is introduced to the investigation of each part. In this study, Infrared Camera, Thermo-vision 900 was used in order to investigate. Infrared Camera usually detects only Infrared wave from the light in order to illustrate the temperature distribution. Infrared diagnosis system can be applied to various field. Also, it is more effective to analyze temperature distribution on the machining center main-axis process.

옥수수수염 차의 MPSS 처리에 의한 위해미생물의 살균 효과에 대하여 연구하였다. 옥수수수염 차에 E. coli와 L. monocytogenes를 5~6 log CFU/㎖ 수준으로 접종하고, MPSS 처리한 후 25℃에서 12일 동안 저장하면서 실험하였다. E. coli는 1, 2, 3 회 MPSS 처리 후 각각 1.14, 2.49, 5.72 log CFU/㎖의 감균 효과를 보였고, L. monocytogenes는 MPSS 1, 2, 3회 처리 후 각각 1.93, 4.49, 6.62 log CFU/㎖의 감균 효과를 보였다. 또한, E. coli와 L. monocytogenes 모두 MPSS 4회 처리 후에는 모두 사멸되었고, 저장 12일까지 검출되지 않았다. 그리고 MPSS 처리는 옥수수수염 차의 TPC 에 부정적인 영향을 끼치지 않았고, 탁도는 4회 이상 MPSS 처리에 의해 향상되었다. 따라서 본 연구 결과, MPSS 처리는 옥수수수염 차의 품질 유지와 더불어 미생물 생육 억제가 가능하기에 옥수수수염 차의 살균에 MPSS를 적용할 수 있다고 판단된다. Inactivation of foodborne pathogenic bacteria in corn silk tea was evaluated using a microwave plasma sterilization system (MPSS). Corn silk tea was inoculated with Escherichia coli and Listeria monocytogenes, treated with an MPSS treatment, and stored at 25℃ for 12 days. The one, two, and three cycles of treatment with MPSS reduced the population of E. coli by 1.14, 2.49, and 5.72 log CFU/㎖, respectively, compared to that of the control. In the case of L. monocytogenes, one, two, and three cycles of MPSS treatment reduced the population by 1.93, 4.49, and 6.62 log CFU/㎖, respectively. Both E. coli and L. monocytogenes were eliminated within four cycles of treatment with MPSS, and even after 12 days of storage, the bacteria were not detected. Total polyphenol content in the corn silk tea did not change much among treatments, and turbidity of the corn silk tea improved following four cycles of MPSS treatment. These results suggest that MPSS treatment can be useful for improving the microbial safety and quality of corn silk tea during storage.

네트워크 침해 유형이 특정 호스트나 서버를 목표로 하여 개별 시스템이나 해당 시스템이 제공하는 서비스에 대한 공격에서 광역 네트워크 서비스 제공에 대한 공격으로 변화 하고 있다. 또한 네트워크 인프라의 속도가 증가되고 서버들의 성능이 개선됨에 따라서 공격 피해의 전파 속도 또한 빨라지고 있다. 야에 따라서 웜은 그 특성상 빠른 공격이 예상된다. 따라서 본 논문에서는 웜을 통한 공격으로부터 네트워크 인프라를 보호하기 위해서 SSDT(System Service Dispatch Table)를 이용한 웜 탐지 시스템을 설계 및 구현한다. The specific host or the server is appointed as a goal and the server has the network breach type in an attack to the individual system or the service which the corresponding system provides to the attack about the wide area network service providing with a change. Moreover, as the speed of the network infrastructure is increased and the performance of the servers is improved, the speed moreover gets raged with the propagation velocity of the attack damage. Accordingly, as to the worm, the fast attack of the on characteristic real-time is predicted. Therefore, in this paper looked, it tries to design and implementation of the worm detection system for protecting the network infrastructure from the attack through the worm.

본 논문에서는 웜의 변종과 Polymorphic Worm, 그리고 알려지지 않은 공격이 보안 패치나 시그니처가 생성되기 전에 발생하는 Zero-Day 공격에 실시간으로 대응하기 위하여 Polymorphic 웜의 자기복제 성질을 이용한 탐지기법에 대하여 연구하였고, 이를 기반으로 SSDT (System Service Dispatch Table)를 이용한 웜 탐지 시스템을 설계 및 구현하였다. 구현된 시스템은 SSDT를 커널 모드에서 액세스하여 시스템 콜을 모니터링 하는 가상의 디바이스 드라이버와 모니터링 된 데이터를 저장하고 분석하는 분석 시스템으로 구성된다. 모니터링 된 데이터는 GSR구조에 따라 분석하였으며, 자기 복제 성질을 갖는 웜의 GSR을 이용하여 시스템의 웜 탐지 여부를 시뮬레이션하였다. In this paper, we studied about detection technique by self-replication nature of Polymorphic worm to real time cope with Zero-Day attack such as worm variant and Polymorphic Worm, and unknown attack of worm those happen before security patch or signature is created. Also we designed and implemented worm detection system that use SSDT(System Service Dispatch Table). The implemented system is consist of virtual device driver that monitor system calls by access to SSDT in kernel mode and analyze system that store and analyze the monitored data. We analyzed the monitored data considering GSR(Gene of Self Replication) structure and simulate the worm detection system whether worm is detected or not.
