Objective : The purpose of this study is to research whether Inyeong Chon spot pulse(人迎氣口脈) could be used on application of Ohaeng-acupuncture(五行鍼法). Methods : I research ${\ll}$Naegyeong${\gg}$(內經) and annotations were excerpted and record that notied the Inyeong Chon spot pulse(人迎氣口脈). Results : Comparison of Inyeong Chon spot pulse and Deficiency Excess syndrome of meridian system is useful to use Zheng Ge(正格) and Sheng Ge(勝格) of Ohaeng-acupuncture(五行鍼法) but in application of Han Ge(寒格) and Re Ge(熱格), Inyeong Chon spot pulse(人迎氣口脈) is not useful.

Tinnitus is usually due to insufficiency of Kidney-essence, asthenia of the Spleen and Stomach, diseases caused by exogenous pathogenic factor, Liver fire(肝火) by severe stress, Phlegm -fire(痰火) by surfeit of high caloric food and alcoholic liquor. I observed and treated four patients who had been diagnosed with tinnitus of Liver-fire(肝火) and Phlegm-fire(痰火). After I checked the Inyeong(人迎) and the chon spot(寸口), all of their Inyeong were stronger than chon spot. Unbalance of the Inyeong(人迎) and the chon spot(寸口), and symptoms of tinnitus were removed by Acupuncture therapy of three Yang meridians of the hand(手三陽) and three Yang meridians of the foot(足三陽).

Pulse-feeling took its origin from making a diagnosis along meridians in the course of discovering and forming meridians and for a long time its meaning was mixed with meridians in the course of recognizing "The Pulse" then was separated from meridians in the early days of Western Han Dynasty. Ancient pulse-feeling methods are pulse-feeling method by the twelve regular meridians, pulse-feeling method by three regions and nine modes, pulse-feeling method by Inyeong(人迎) and Chon-gu(寸口), etc. Pulse-feeling was changed in proportion to diagnostic purpose and method of treating and if method and region of pulse-feeling is arranged, we will infer correlation between meridians and pulse-feeling and will infer transitional system of past pulse-feeling and will forecast transition of future pulse-feeling. As the result that I study the transition of the above three pulse-feeling methods of meridians diagnosis: 1. Three pulse-feeling methods of meridians diagnosis flowed into diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ and were changed into diagnostic method being fit for use of five Su points, The Front-Mo points and Back-Su points that grasp the pathology of mutual internal organs and treat the disease. 2. Today it is suggesting the transition of another pulse-feeling method that do not apply diagnostic method by taking pulse of setting six region for Chon(寸), Gwan(關) and Cheok(尺), i.e. the Chon[寸] spot pulse of $\ll$Nan-gyeong$\gg$ to 19C Sasang(四象) Constitutional Medicine or 20C Eight Constitutional Medicine.

This present study tried to observe an each feature that the difference of Neijing(內經) and Nanjing(難經) descriptions about the three-portion and nine-position pulse taking(三部九候脈). It was interpreted and contradistinguished that discrimination of position, diagnosis object, and the perceptions of Earth of the center among the Five Phase of each literature were described in Neijing and Nanjing for the three-portion and nine-position(三部九候). In Neijing, the three-portion and nine-position method divided three parts the whole body. Then the each three parts again divided with Heaven, Earth and Man(天地人). About the corresponding parts of pulse diagnosis, there mentioned for the head and the Zang-Fu organs(臟腑), but not mentioned for the hand and foot. In addition, Earth is assigned to the Earth(土), an each Earth accounted for the source of life. In Nanjing, three-portion divided Chon, Gwan, and Cheok(寸關尺) and each spots separated three stage of pulse taking. For the pulse taking spots and diagnosis, there mentioned the hand and foot instead of the unclear mention of Zang-Fu organs. Then Gwan spot and middle stage of pulse taking were assigned to the Earth, respectively. It was emphasized stomach Qi(胃氣) that the region of Earth, Gwan spot and middle stage among the pulse taking spots each literature were described in Neijing, Nanjing.

Objectives : To obtain pulse information, oriental medical doctors usually use the three finger pulse diagnosis method. Although the diagnostic positions are very important, the exact positions are not known because of the uncertain conversion of measures of length (bun, chon, chuk) and misunderstanding of the related concepts of oriental medicine. In this study, we proposed relative positions for the detection of three pulses with a pulse analyzer. Methods : The proposal was made based mainly on several literature reviews, especially the original texts, and the examination of anthropometric characteristics of 78 individuals. Results : The Kwan is the spot where the radial pulse can be felt well near the eminent head of the radius at wrist, high bone. The position of Chon should be apart from Kwan by 6/10 distance between the high bone and wrist joint of each individual. Finally, the position of Chuk is apart from Kwan by 6.5/100 distance between the high bone and the elbow joint of each individual. Conclusions : Adapting those proposed positions for measuring three pulses can provide more consistent information to what an oriental doctor obtains than a pulse analyzer applied to other positions.

White-spot syndrome virus (WSSV) is a devastating, infectious virus affecting shrimp. Although sensitive techniques involving PCR have been developed to assist farmers in screening shrimp (brood stock) for WSSV prior to stocking ponds, such practices have not yet been applied in Korea. Despite the rationality of implementing screening, there has been some doubt as to whether the stocking of WSSV-PCR-negative fly epidemiologically decreases white-spot disease outbreaks. Here, we report a retrospective analysis of data from shrimp farms in the western coast of Korea where WSSV-PCR-negative brood stocks were used to stock rearing ponds. A total of 366 shrimp from Heuksan Island were sampled for WSSV with PCR. Of the tested shrimp, 7.2% (28 brood stocks) were identified as WSSV positive; only WSSV-PCR-negative shrimp were used for brood stocks. Total unit production (final shrimp production/ the area of the ponds) was higher, at 1.96, in ponds where WSSV-PCR-negative shrimp were used, as compared with 1.02 in other ponds in Korea in 2004. This retrospective analysis of WSSV in Korea may be useful to the shrimp aquaculture industry, suggesting a testable hypothesis that may contribute to the eventual control of WSSV outbreaks.

포토 다이오드(photodiode) 조정 방식을 이용해서, 비전 시스템을 장착한 고가의 정밀 자동 조립조정 장비 없이 홀로그램 픽업 모듈을 제작하는 새로운 방법을 제안하였다. 저가격화를 위해서 리드 프레임형의 반도체 레이저와 COB(Chip on Board)형의 포토 다이오드를 사용했고, 초점 에러 신호(focus error, FES) 검출방법은 스팟 사이즈 검출법(spot size detection, SSD), 트랙 에러 신호(tracking error, TES) 검출방법은 삼빔법(3 beam method)을 이용했다. 이를 만족하는 픽업 홀로그램 모듈 광학계를 설계하고, 조립조정 프로세스 수립 및 시스템을 제작하였으며, 조립된 홀로그램 모듈을 이용하여 CD에서 데이터를 검출하는 실험을 통해 제안된 포토 다이오드 조정방식의 유용함을 입증하였다.

In The case of the bridge which is located in the downstream of the dam, effect of the running water and stability of the bridge is studing by using the Hydraulic model test. 1. The water level change of 'Seosang1 bridge' along Chunchon dam spill occurred through this experiment more greatly than a numerical conspiracy. 2. Bight is the spot where a difference occurs in located bridge piers(p18-p28) greatly, and an influence of Chunchon dam occurs in greatly.

위장조영검사는 X선을 사용하는 검사로 검사 부위 외의 다른 장기의 피폭이 발생한다. 위장조영검사에서 갑상선, 수정체, 유방, 생식선 등 생물학적으로 방사선감수성이 상대적으로 높은 표적장기가 주변에 분포되어있기 때문에 방사선 피폭에 대한 방어를 하는 것이 중요하다. 장기별 측정 깊이의 선택이 가능한 전신 팬톰을 제작하고 안구, 갑상선, 유방, 생식선의 방사선 피폭선량을 측정하였다. 투시만 시행하였을 경우 수정체, 갑상선, 유방, 생식선의 평균 피폭선량의 감소는 62.2%로 나타났고, 투시와 Spot 촬영을 동시에 시행하였을 경우 수정체, 갑상선, 유방, 생식선의 평균 피폭선량의 감소는 59.0%로 나타났다. 따라서 위장조영검사 시 수정체, 갑상선, 유방, 생식선의 차폐가 이들의 피폭선량 감소에 효과가 있었다는 것을 확인할 수 있었다. 제작한 인체 팬톰은 인체에 위치한 장기에 해당하는 높이를 조절할 수 있기 때문에 심부선량 측정에 사용될 수 있을 것이다.

엑스선유방촬영술은 다양한 유방질환 중 석회화 병변을 진단하는데 가장 효과적인 방법이다. 환자의 의료피폭 저감과 진단에 필요한 최적의 영상을 얻기 위해서는 성능유지를 지속적으로 관리해야 한다. 엑스선유방촬영술에서 엑스선을 발생시키는 양극의 경사각도는 중심선을 기준으로 하기 때문에 조사야 내의 위치에 따라 엑스선관의 유효초점이 미세하게 달라질 수 있어 공간분해능의 차이가 발생할 수 있다. 본 연구에서는 디지털 엑스선유방촬영장치에서 검출기 위치에 따른 LSF를 측정하여 MTF를 계산함으로써 공간분해능 변화에 대해서 연구하였다. 와이어 직경에 대한 변화에서 $50{\mu}m$ 직경의 와이어의 경우 가장 높은 공간주파수 값을 나타냈으며 검출기의 픽셀보다 작은 직경을 갖는 와이어를 사용해야 검출기의 공간주파수에 따른 응답을 바르게 구할 수 있다는 것을 알 수 있었다. 조사야 내의 검출기의 위치에 따라서 공간주파수는 중심부분의 와이어가 나머지 와이어보다 우수한 MTF 특성을 보였으나, 그 차이는 미소하게 나타났다. 또한 중앙부분에서 반치폭 또는 유효초첨이 가장 작게 나타났으며 중앙에서 벗어날수록 반치폭이 증가하여 공간분해능이 낮아진 것으로 나타났다.
