This paper discusses the evaluation of the safety impact of the Adaptive Cruise Control (ACC) system in Korea. To evaluate the safety impact, this paper suggests an analysis method by using the test scenario and field operational test data. The test scenario is composed to represent the main component factor of the ACC system and ACC related accident situation such as rear-end collision, lane-change, and road-curvature, etc. Also, from the field operation test data, the system's potential to increase the safety can be measured ideally. Besides, field operational testdata was used to revise the expected safety impact value as Korean road conditions. By using the proposed evaluation method, enhanced safety impact of the ACC system can be estimated scientifically.

Objectives : The aim of this study was to examine the effects of electroacupuncture(EA) at the BL60 (Kollyun) on normal humans using power spectral analysis. Methods : EEG power spectrum exhibit site-specific and state-related differences in specific frequency bands. In this study, power spectrum was used as a measure of complexity. 30 channel EEG study was carried out in 10 subjects $(10\;males;\;age=22.4{\pm}0.5$ years). Results : In alpha band, the power values at Fz during the non-acupoint treatment and at Fp2, T5 during the BL60-acupoint treatment significantly were decreased. In beta band, the power values at C3, Po2, O2, Oz during the BL60-acupoint treatment significantly were increased than the before-acupuncture treatment. In theta band, the power values at F7 during the BL60-acupoint treatment significantly was increased. However, the comparison with that before and after the treatment shows no significant differences in all channels.

Recent trend changes a criterion for evaluation of humors that environmental problems are raised as a global issue. Burners with higher thermal efficiency and lower oxygen in the exhaust gas, evaluated better. To comply with environmental regulations, burners must satisfy the NO/sub x/ and CO regulation. Consequently, 'good burner'means one whose thermal efficiency is high under the constraint of NO/sub x/ and CO consistency. To make existing burner satisfy recent criterion, it is highly recommended to develop a feedback control scheme whose output is the consistency of NO/sub x/ and CO. This paper describes the development of a real time flame diagnosis technique that evaluate and diagnose the combustion states, such as consistency of components in exhaust gas, stability of flame in the quantitative sense. In this paper, it was proposed on the flame diagnosis technique of burner using Neuro-Fuzzy algorithm. This study focuses on the relation of the color of the flame and the state of combustion. Neuro-Fuzzy loaming algorithm is used in obtaining the fuzzy membership function and rules. Using the constructed inference algorithm, the amount of NO/sub x/ and CO of the combustion gas was successfully inferred.

Arthrocentesis is a simple, less invasive, inexpensive, and highly efficient procedure for closed lock of the temporomandibular joint with regard to the lack of recurrence of symptoms during extended periods of follow-up and significiant improvement in pain and jaw function. It can be performed under local anesthesia. Arthrocentesis closed lock provide sustained normal joint function and marked pain relief. This study is the clinical outcome of arthrocentesis for closed lock of the temporomandibular joint. 160 patients(169 joints) who had experienced sudden-onset, persistent limited mouth opening were the subjects of this study. Arthrocentesis of the upper compartment of the affected TMJ was performed using normal saline. As results, at 3-60 months postarthrocentesis maximum mouth opening(MMO) had increased from mean of 27.7mm to 43.5mm, contralateral movements(CLM) from mean 5.74mm to 9.55mm, midline deviation during mouth opening from mean 3.04mm to 0.69mm. In 130 cases there was a history of joint noises, in 52 cases all noise had ceased after procedures.

The band-gap reference voltage generator which can be operated by low voltage is proposed in this paper. The proposed BGR circuit can be realized in logic process by using parasitic NPN BJTs because a $Low-V_T$ transistors are not necessary. The proposed BGR circuit is designed and fabricated using $0.18{\mu}m$ triple-well process. The mean voltage of measured VREF is 0.72V and the three sigma$(3{\sigma})$ is 45.69mv. 본 논문에서는 $Low-V_T$ 트랜지스터가 필요 없는 로직공정으로 Parasitic NPN BJT를 이용하여 저 전압에서 동작 가능한 밴드갭 기준전압 발생기 회로를 제안하였다. $0.18{\mu}m$ triple-well 공정을 사용한 BGR회로를 측정 한 결과 VREF의 평균전압은 0.72V $3{\sigma}$는 45.69mV로 양호하게 측정되었다.

Dimensional synthesis of planar and spatial mechanisms mostly requires solution-finding, procedure for a system of polynomial equations. In case the system is nonlinear, numerical techniques like Newton-Raphson are often used. But there are no logical ways for finding all possible solutions in such iterative methods. In this paper, algebraic elimination is used to get all solutions for the synthesis of 5-SS spatial mechanism with seven prescribed positions. The proposed algorithm is more suitable for computer implementation and takes less time than existing one. Two numerical examples are given to demonstrate the implemented algorithm.

LLRP(Low-Level Reader Protocol)는 RFID 리더(LLRP 서버)와 RFID 어플리케이션들(LLRP 클라이언트)간의 인터페이스를 기술하고 있다. LLRP 서버는 여러 기능들을 동시에 수행해야 한다. 본 논문에서는 LLRP 서버를 멀티 쓰레드 구조로 설계한다. 이를 위하여 (i) LLRP 서버와 클라이언트들 간의 동작 절차를 분석하고, (ii) LLRP 서버가 만족해야 할 기능적인 요구조건들을 제시하고, (iii) 그 요구조건들을 만족할 수 있도록 LLRP 서버의 역할을 여러 쓰레드로 나누고, (iv) 쓰레드 수준에서 LLRP 동작 절차를 세분하였다. 설계된 구조를 검증하기 위하여 이산사건 시스템을 계층적이고 모듈화된 방식으로 기술하는 언어인 DEVS 형식론을 이용하여 설계된 내용을 모델링하고 시뮬레이션 하였다. 시뮬레이션 결과, 제안된 구조는 LLRP 표준과 주어진 모든 기능적 요구 조건들을 만족함을 알 수 있었다. LLRP (Low-Level Reader Protocol) specifies an interface between RFID readers and RFID applications, also called LLRP servers and clients respectively. An LLRP server should concurrently execute various functions. This paper designs an LLRP server of a multi-threaded architecture. For that, (i) the operational procedure between LLRP servers and clients is investigated, (ii) the functional requirements of LLRP servers are presented, (iii) the operation of an LLRP server is decomposed into several threads to satisfy those functional requirements, and (iv) the operational procedure is further examined in thread-level. To validate the designed architecture, it is modeled and simulated by using the DEVS formalism which specifies discrete event systems in a hierarchical, modular manner. From the simulation result, we can conclude that the proposed architecture conforms the LLRP standard and satisfies all the given functional requirements.
