  • This paper presents a genetic algorithm based autonomic movement algorithm for an autonomous underwater vehicle(AUV) and verified it to simulation. Also, developed program that can do simulation on two dimension and three dimension in seabed environment. The presented algorithm is applicable to a escape from the recursive search and a development of obstacle avoidance system.

  • 유비쿼터스 환경은 어디서든지 항상 컴퓨터 액세스가 가능한 세계를 뜻한다. 유비쿼터스 환경에서의 멀티 에이전트들은 객체들의 상황을 인지하고 그 상황에 따르는 이벤트 메시지를 서로 전달한다. 본 논문은 유비쿼터스 환경에서 각 개인의 위치를 인지하여, 최적의 환경을 만들어주기 위한 온톨로지 기반의 멀티 에이전트 시스템을 제안하고 다음 두 가지 부분의 중점을 두어 시스템을 설계하였다. 첫째, 각 객체의 위치와 상황을 인지하는 센서기반의 상황인지 시스템을 이용하여 이벤트 메시지를 서로 주고받는 온톨로지 기반 에이전트들을 설계한다. 둘째, 각 객체의 현재 상황과 위치를 기준으로 객체에 맞는 이벤트를 추론하는 추론 엔진을 설계한다.

  • We have proposed and demonstrated an gas-flow sensor using optical fiber bragg grating(FEG). The flow sensor has no electronics and no mechanical parts in its sensing part and the structure is th11s simple and immune to electromagnetic interference(EMI). The FEG sensor was consisted qf the sensing element and a coil heater. The metal coil was used to supply the current to the FEG. While some currents supply to the coil, the refractive index of the FEG under the coil is changed and thus the wavelength shift of fiber optic sensor was induced In this work, the wavelength shift according to flow-rate was experimentally studied and was used to evaluate the gas flow-rate in a gas tube. As a result, it was possible to measure the flow-rate in a linear range from 5 to $20{\ell}/min$ with a resolution of approximately $1{\ell}/min$ at the applied currents of 100 mA and 120 mA. The measured sensitivities were $15.3\;pm/\ell/min$ for 100 mA and $20.2\;pm/\ell/min$ for 120 mA.

  • Objectives : This study was to compare effects of scalp acupuncture with usual acupuncture on peripheral facial palsy in comparison with usual acupuncture only. Methods : We investigated 40 cases of patients with peripheral facial palsy, and devided patients into two groups: We treated one group by scalp acupuncture with usual acupuncture and did the other group by usual acupuncture only. To evaluate the effectiveness of treatment applied for two groups, we used Gross Grading System of House-Brackmann(H-B grade), Yanagihara's Unweighed Grading System(Y system). Results : 1. In H-B grade group B(common acupuncture therapy and scalp acupuncture)'s score was reduced than group A(common acupuncture therapy), but there was no statistical significance. 2. In Y-system group B was higher than group A, but there was no statistical significance. Conclusions : There was no stastical significance between two groups : treated by scalp acupuncture with usual acupuncture and usual acupuncture therapy only, on peripheral facial palsy.

  • Objectives: This study was done to establish the anatomical meaning of the term 'Geun(筋)'. Methods: Through analysis of 《HwangJeNaeGyeong(黃帝內經)》, the meaning of 'Geun(筋)', 'GeunMag(筋膜)', 'Yug(肉)', and 'Gi(肌)' were established. Based on analysis, the anatomical meaning of the 'Meridian-muscle(經筋)' was studied by comparing it with anatomy. Results & Conclusions: 'Gyeong(經)' is recognized as a metaphysical expression and "Geun(筋)" means myofascia in anatomy. The concept of 'Geun(筋)' includes the epimysium and perimysium, as well as tendons and ligaments, which are extensions of these. 'Fascia', refers to the fascia of the whole body, and also appertain to 'Geun(筋)'. 'Yug(肉)' means endomysium, muscle fiber, and adipose tissue and layer. The word 'GeunMag(筋膜)' used in the 《HwangJeNaeGyeong(黃帝內經)》 means anatomically a 'tendon'. Therefore, 'Muscle' should be translated as 'GeunYug(筋肉)' in Traditional medicine. 'Meridian-muscle(經筋)' can be defined as the longitudinal muscle and fascia system, which is the basis of whole body encompassing dynamics.
