  • RF-ID technic will got over not only damage which can be caused by contact ID technic but also worse awareness with the lapse of time. In advance, for subway the fares of mass transportation at rush hours of the days, it's important to find a way to collect fares without unnecessarily delaying passengers. In this paper. we are proposing RF-ID system using the RF Communication Technic and Energy Transformation Technic.

  • Purpose: The purpose of this study was to assess how much neurac technic affects the stability muscles of the shoulder according to the supporting surface in crawling position. Method: 29 healthy adult males participated in this experiment. The experiment consists of 2 experimental groups and 1 control group. It is conducted for 3 weeks. Each group exercised for 7 seconds and then rested for 3 seconds. Using EMG, the average value of serratus anterior, upper trapezius, and lower trapezius was repeated three times. Experimental group 1 conducted push up plus exercise applied neurac technic with sling on unstable supporting surface. Experimental group 2 conducted push up plus exercise applied neurac technic with sling on stable supporting surface. Control group conducted the push up plus exercise on stable supporting surface. One-way ANOVA was used for statistical analysis. Result: It was noticeable that the result of Experimental group 1 affects stability muscles of more than Experimental group 2 and Control group. Conclusion: Push up plus position applied neurac technic with sling on unstable supporting surface was the most effective in activating the stability muscles of the shoulder.

  • Objectives : Donguibogam Chimgupyun has a sort of acupuncture technic in Josun called Gyejokchimbub. This Gyejok refers to the habgogja of Ling shu guanzhen. This was conveyed to Japan as Shinkyugokuhitsuto's Betsutsuto but it is unclear as to how this is used today. Methods : Medical texts such as Donguibogam, Huangdineijing Lingshu, Yixuegangmu, Shinkyugokuhitsuto, Sugiyamamakototsutoryu, and Shinkyusuyo were studied for this research. Results : Gyejok acupuncture is conveyed to Japan as Shinkyugokuhitsuto's Betsutsuto but it is unclear as to how this is being used. What is similar to this technic is the Sanhoshujutsuho in hand technic's part and Sanhohariden in Juhachijutsu's Kuden which are shown in the chapter five of Book of Hyo. Moreover, this Sanho is Lingshu Guanzhen's Qici. This was continued as Sugiyamamakototsutoryu's Sanhoshujutsuho, but sansin in needle technic is similar to Gyejog, and it was branched out into Sanhoshujutsuho that is orally transmitted from Sanhoshiyuji as seen in the same book, Juhachijutsu's principal treatment. Conclusions : Habgogja is a 'Gyejog Tsuto' originating from Gyejog technic, and Qici is Sanho originating from Santoge. They developed into Sanhohariden from Sanhoshujutsuho. This tells us how Gyejog acupuncture technic has affected East Asia.

  • Subtraction is an essential technic to improve imaging quality in various radiological procedures. The limitations of subtraction, however, are well known. Blurred under-subtraction (BUS) method has been suggested to overcome and compensate these limitations. Ten cases of angiography were subtracted by conventional subtraction and BUS technic. Results of this study revealed that BUS method is simple to perform and imaging quality obtained by BUS is excellent. Comparing to conventional subtraction, BUS method has advantages. For example, BUS need no mask film or no immobilization of patient during examination. Improvement of imaging Qualify is achieved by edge enhancement, homogeneous blurring of background density and increasing contrast. With emphasis of its simplicity in technic, we would report that BUS method is a useful adjunct imaging technic in various radiological procedures.

  • Electrical properties of Large-grain-size TIT with 7/7 ${\mu}m$ channel width and length which gate insulator is made of 20nm $SiO_2$ and 80nm $SiN_x$. was fabricated and measured with Large-grain-size technic(MICC) and compared to ELA technic's data. The field-effect mobility was decreased from 106.78 to $88.74\;cm^2$/Vs and threshold voltage also decreased from -1.8382 to -0.9529 V, when TFT process is changed from ELA technic to MICC technic. Subthreshold swing, also, increased from 0.22 to 0.32 V/dec and $I_{on/off}$ ratio decreased from $1.12{\times}10^8$ to $5.75{\times}10^7$.

  • 음향 전력 증폭기의 출력단에서 발생하는 비선형성을 보상하는 디지털 신호 처리 기술을 제안하고 그 모의실험 결과를 제시한다. 음향 전력 증폭기에 사용되는 소자에 의한 비선형성을 간접학습구조와 적응형 필터로 구성되는 디지털 신호 처리 기술로 보상한다. 적응형 필터를 사용함으로써 증폭기의 비선형 특성이 시간적으로 변하더라도 이를 적응적으로 보상할 수 있다. 모의실험 결과 전치 보상기는 3 차의 다항식으로 구현할 수 있으며 홀수차 비선형성을 효과적으로 제거할 수 있음을 보였다. 짝수 차 비선형은 출력 신호에 존재하는 직류 옵셋이 가장 큰 부분을 차지하며 이는 제안하는 기술로는 제거가 어려우므로 바이어스 회로 설계 시 유의해야 한다. 제안하는 기술은 아날로그 시스템의 본질적 특성 결함을 디지털 신호 처리 기술로서 보상할 수 있음을 보여준다.
