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.

Digital medical image commenced with an introduction of PACS has become more popular today in the radiation diagnosis and radiation treatment and made great progress, in particular, for medical testing field, whereas it has made slow progress for radiation treatment field. In order to accommodate the current trend of digital from analog, a spherical mechanical check device(SMCD) that is the form of spherical differing from the existing form of flat or cube has been designed and tested its practicability to replace the part in mechanical check with digital image from QA operation. If the distance maintains constance between source(target) and image detector with constant distance to the center of spherical mechanical check device(SMCD), the size will be shown as a constant image at all times regardless of its direction exposed. For the test, two accurate hemispheres are made and put together which results in a sphere of the equilateral circle. It enables a variety of implementation of the existing mechanical check using digital image as follows: congruity level of radiation field and light field, size accuracy of radiation field and collimation field, gantry rotation isocenter check, collimation rotation isocenter check, room laser accuracy check, collimation rotation angle check, couch rotation angle check, and more. In addition, it has proved its practicability in checking isocenter congruity level as real time at the time of simultaneous rotation between gantry and couch that is applied to the non-coplanar field, which had been hard to apply as a device formed of existing flat or cube.

This study evaluates the flow of Taoism in the change of knowledge that accompany the passage of time beyond school-centered studies. In particular, it is to understand the Tao(道) and T'ien(天) of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" in the thought of T'ien at the time. The thought of T'ien at that time was based on the T'ien in "Mencius". There are two meanings of T'ien in "Mencius", and also of T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$". This study examins that idea that the T'ien in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were influenced by the thought of T'ien in "Mencius". It also reveals the T'ien theory of Wang Ch'ung(王充) which is influenced by Taoism. Also, in the course of examining the relation of T'ien theory of Wang Ch'ung with T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$", it is more embodied that T'ien theories of "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" were affected by the previous T'ien theories. Furthermore, the meanings of Tao in "Lao $Tz{\check{u}}$" and "Chuang $Tz{\check{u}}$" are revealed.

In offline check systems, a client does not have to pay the exact amount. Instead, a client refunds the difference between the check value and the paid amount. In most offline systems, clients can not spend the remainder. But if the refund can be made spendable, it would provide a more convenient payment method. In this paper, we present a new offline system, which allows refunds to be reused as payments. In our system, the shop issues a new check using its private key for the difference. This new check, called the refund check, can be spent in the same way as checks issued by the bank. If the refund check is deposited to, or refunded at the bank, the bank charges the issuer of the check for the amount. The form of a check in this system is much simpler than previous check systems. It also uses a more flexible and efficient denomination method. The refund check is unlinkable to the check used in the payment where the refund check was issued. This system provides coin and owner tracing mechanisms to reinforce controls on illegal use of anonymous checks and was designed with consideration to the atomicity of transactions.

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.
