The purpose of this study is to investigate the aesthetic characteristics of check fashion of the 20th century and to analyze the formativeness for them shown in recent collections. The results of this study are as follows; 1) Before the First World War, check patterns were used for S silhouette dresses and hobble dresses. During the two wars, they were used for garçonne style dresses and military suits. Check patterns were used for mini style in the 1960s, uni-sex style in the 1970s, and power suits in the 1980s. Especially after the 1980s, check patterns have followed the fashion trend of each season and appeared in retro styles. Consequently, the aesthetic characteristics of check dresses of the 20th century are traditionality, ornamentation and eclecticism. 2) Traditionality of check fashion shown in recent collections was implied in the classic styles like suits with its grey glen check, avant-garde styles like boxy coat with its dark blue tartan check, and so forth. Ornamentation was shown in the modern styles like jackets decorated with block check colored white and black, casual styles like bomber jackets with hound tooth check colored white and black, and so forth. Eclecticism was reflected in the romantic styles like one-piece dresses with hound tooth check colored white and light blue, elegant styles like low-cut dress with its dark blue window pane check, ethnic styles like long cape with gingham check colored white and black, and so forth.

In this paper, a study on a wireless check-up method of test equipment for captive flight test(CFT) was conducted. For CFT, test equipment is mounted on a POD, and check-up is carried on the test equipment's. For check-up the POD wirelessly, battery, power distribution unit, wireless communication devices were designed within the POD, and a check-up device is designed outside of the POD. Once the external check-up device sends a 'start signal' to the POD, it performs the overall check-up procedures and transmits the 'end signal' to the external check-up device. Detailed check-up results are stored in an internal storage device, and are possible to read from external check-up device if necessary, thereby improving the reliability of the wireless check-up. By implementing and applying these wireless check-up system, the reliability of the check-up was enhanced by dynamical and movable check-up, and safety is guaranteed as the check-up was carried without access to the aircraft.

Tongmu I Je-ma(1837-1900) set up Sasang Constitutional Medicine(四象體質醫學), a medical theory that would be original in the Korean medical history through his book ${\ll}$Tang-uisusebowon(東醫壽世保元)${\gg}$. In this book, he writes that he found the clue to his sasang Constitution(四象體質) theory from ${\ll}$Hwangjenaegyong(黃帝內經)${\gg}$. But the main logic that gives shape to the Constitution(體質) theory is $s{\check{o}}ng-ch{\check{o}}ng$ theory(性情論) of Confucian. Therefore, Tongmu(東武)'s Constitution $s{\check{o}}ng-ch{\check{o}}ng$ theory(體質性情論) is fundamentally based on confucian thoughts. Kongmaeng(孔孟) saw $s{\check{o}}ng$(性) as a base for connecting the entire mankind to be united, and $ch{\check{o}}ng$(情) as a individual thing that can exalted differently according to one's state of mind. Chuja(朱子) weakene the human's active volition by dividing $s{\check{o}}ng$ and $ch{\check{o}}ng$ as ibal(理發) and kibal(氣發) and therefore describing mankind to be submitted to Heaven's will. On the other hand Yolgok(栗谷) generalized $s{\check{o}}ng-ch{\check{o}}ng$ in the active mind of man himself by saying that $s{\check{o}}ng$ is when i-ki(理氣) does not act as a bodily function of the mind and $ch{\check{o}}ng$ is when it does. Furthennore he emphasized man's activeness on pursuing good by saying that the division of good and bad does not start from the origin of motion but is divided by the condition of ki(氣) which leads motion. Tongmu, who was influenced by Yulgok linked both $s{\check{o}}ng$and $ch{\check{o}}ng$ through, happiness, anger, sadness, pleasure(喜怒哀樂), and saw $s{\check{o}}ng$ as the ability to recognize good which is in the kijil(氣質) formed from the integration of i-ki, and saw $ch{\check{o}}ng$ as $s{\check{o}}ng$ blurred by man's greed. In addition to this, he says that the direct connection between each person's divergence in $s{\check{o}}ng-ch{\check{o}}ng$ and the condition of Four-organ(四臟) which is ki, not the mind which is i(理) forms sasangch'ejirin(四象體質人). His theory that illness comes from the partiality of $s{\check{o}}ng-ch{\check{o}}ng$ and therefore can prevent this by clarifying the mind and adjusting $s{\check{o}}ng-ch{\check{o}}ng$ through volition, has led Korean oriental medicine to be human based.

Various interpretations on the boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system, and on the geologic structure and stratigraphy of the $Okch{\check{o}}n$ system have been yielded by the previous studies, and they are still in hot debate. The present work has mainly studied on the boundary between the $Okch{\check{o}}n$ and $Chos{\check{o}}n$ systems in the south of $Jech{\check{o}}n$, and the geology in its vicinity to clarify the previous misinterpretations if any on the geologic structure and in trun stratigraphy of the area concerned. The boundary between the $Okch{\check{o}}n$ system and the Great Limestone series of the $Chos{\check{o}}n$ system has been thought to be (1) gradational relation which means two systems are the same formation, (2) unconformable relation in which the $Okch{\check{o}}n$ system overlies the $Chos{\check{o}}n$ system, (3) unconformable relation in which the $Chos{\check{o}}n$ system overlies the Okchon system indicating that the age of the $Okch{\check{o}}n$ system is Precambrian, and (4) fault contact in which the $Okch{\check{o}}n$ system of Precambrian age comes in contact with the $Chos{\check{o}}n$ system of Cambro-Ordovician age. The present study clearly found that the relationship between the two systems is a fault zone contact. Shear zone of a width of 300 to 400m is developed, and andesitic volcanics and basic dikes are intruded along the fault zone. This fault contact is exactly the north extension of the Bonghwajae fault, which was denominated long time ago by two of the present authors. The eastern side of the fault has been uplifted so that the $S{\check{o}}changri$ formation of the $Okch{\check{o}}n$ system cropped out in the zone of the Great Limestone series. All the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, but the present study found an overthrust having a strike of $N8^{\circ}E$ and dip of $30^{\circ}NW$ between them, and the $S{\check{o}}changri$ formation has thrusted over the Great Limestone series at the central part of the study area. In the southern and northern parts of this uplifted $S{\check{o}}changri$ formation, the Great Limestone series rests unconformably on it. In the eastern part of the study area where the Mt. Dangdu is located and the previous workers thought that the $S{\check{o}}changri$ formation rests on the Great Limestone series, Precambrian basement rock whose age is older than 1720+50 m.y. crops out in the northern part of the east-west trending high angle fault, and the Great Limestone series rests unconformably on the basement.

PACS의 도입에 발맞추어 시작된 digital 의료영상은 현재 방사선 진단 및 치료 영역에서 일반화되었으며 특히 진단영역에서는 눈부신 발전을 거듭하고 있다. 치료영역에서의 digital image 구현은 상대적으로 느린 성장과정을 거쳐 오늘에 이르고 있다. 본 논문은 이러한 analog에서 digital로 변화하는 흐름을 인식하여 정도관리(Quality Assurance) 업무 중 mechanical check 부분을 digital image base 업무로 대체하여 수행하고, 기존의 육면체 또는 사각형틀의 개념을 탈피한 구형(球形)의 Spherical mechanical check device(SMCD) 고안하여 그 실용성을 실험하였다. Source(target)에서 image detecter 간의 거리가 항상 일정하고, Spherical mechanical check device(SMCD)의 중심까지 거리가 일정하다면 어느 방향에서 SMCD를 exposure하더라도 그 크기는 항상 일정하게 영상으로 표현 될 것이다. 이를 위해 정확한 반구(半球)를 2개 정밀 제작하여 그것을 합쳤을 때 정원(正圓)의 구(球)가 되도록 하였다. 이를 이용하여 radiation field와 light field의 일치도, radiation field 크기의 정확도($(5{\times}5,\;10{\times}10,\;15{\times}15\;cm)$), Collimator field 크기의 정확도($5{\times}5,\;10{\times}10,\;15{\times}15\;cm$), Gantry rotation isocenter check, Collimator rotation isocenter check, Room laser accuracy check, Collimator rotation angle check와 Couch rotation angle check 등 기존의 mechanical check를 digital image를 이용하여 실행할 수 있었으며, 기존의 Flat 또는 정육면체 형태의 mechanical check device로는 쉽게 하기 힘든 non-coplanar field에 적용되는 Gantry와 Couch가 동시에 rotation되었을 때 그 isocenter의 일치도를 real time으로 확인할 수 있었다.

오프라인 수표시스템에서는 수표의 액면가와 지불대금이 다르면 거스름이 발생한다 대부분의 오프라인 수표시스템에서는 거스름을 지불에 사용하지 못하고 이를 돌려받기 위한 환불 프로토콜을 진행하여야 한다. 그러나 거스름을 지불에 사용할 수 있다면 수표방식은 환불이 필요 없는 편리한 지불 수단이 된다. 이 논문에서는 거스름을 지불에 사용할 수 있는 새로운 오프라인 수표시스템을 제안한다. 새 시스템에서는 상점이 거스름 수표를 발행하도록 하여 이를 지불에 사용할 수 있도록 개선하였다 상점은 자신의 개인키를 이용해서 은행이 발행하는 수표와 동일한 형태의 거스름 수표론 발행하고, 이것이 유통되어 은행에 입금되면 수표의 금액만큼 해당 상점에게 청구하는 방식이다. 이 시스템에서 수표의 형태는 기존 시스템에 비해 매우 간단하며 액면가 표현에 있어서도 제한이 없다. 또한 지불에 사용한 수표와 거스름 수표의 연결이 어려우며, 거스름 수표도 익명으로 지불할 수 있다. 그밖에 수표의 불법적인 사용을 막기 위해 화폐 추적, 인출자 추적이 가능한 조건부 익명성을 제공하고 트랜잭션의 원자성을 보장한다.

In a scroll compressor it is generally accepted that a check valve is necessary to prevent reverse rotation of the scrolls. The check valve is subjected to discharge pulsations and their resultant forces. The flow phenomena around the check valve may affect the efficiency and the noise level significantly. The motivation of this study is to understand the flow phenomena and the unstable motion of the check valve on operating conditions in order to identify reasons raising noise and improve the performance of the check valve. In this study, unsteady flow simulation was performed using CFD and the pressure distribution around the check valve was obtained. This paper also shows that unstable motion of the check valve on standard operating conditions through theoretical analysis and flow visualization.

Check valves playa vital role in the operation and protection of nuclear power plants. Check valves failure in nuclear power plants often lead to a plant transient or trip. An overview of the failure history of check valves needs to identify key area where resources can be best applied to further improve their reliability, and provide cost effective means for failure reduction. The analysis of historical failure data gives information on the populations of various types of check valves, the systems they are installed in, failure modes, effects, methods of detection, and the mechanisms of the failures. The results presented are based on information derived from operating records, nuclear industry reports, manufacturer supplied information. A majority of check valve failures are caused by improper application. Failure modes are identified for swing and lift check valves. Failures involving improper seating and valve disc stuck comprised the largest percentage of failures.
