Background : The application of the delta check in tests in general chemistry detects both random and clerical errors, thus enhancing the reliability of tests. However, since this approach adds the burden of confirming the results to the laboratory, it has the disadvantage of lengthening the turn around time of tests. We speculated that an online delta check system needed to reduce the turn around time. We developed delta quality control system and evaluated its effectiveness of quality control in clinical chemistry. Methods : We developed an online delta check system based on the client-server paradigm. We used IBM PentiumⅢ PC as server and as clients. The database system used was powerbuilder 6.0. Results : In the system we developed, delta screening was performed when test results were input to the computer. The decision over the delta screening was made by comparing it against patient's clinical information and cumulative results within the same screen. Conclusions : The developed delta check method made it available to reduce the turn around time previously spent on delta screening by eliminating the batch processing of tests which was needed in previous approaches separate query cumulative results and patient's clinical informations for screening purposes.

佛像을 通해 본 統一新羅時代 佛衣에 關한 硏究 : 着衣 및 衣褶을 中心으로 focused on the wearing method and clothes fold

李春桂,安明淑 東國大學校 1988 論文集 Vol.27 No.-

The purpose of this study is to investigate Unified Silla's distinctive style and process of change in Buddga's costumes as well as clothes and wearing method of Buddga's costumes. This study lays emphasis on Unified Silla's Age, which is comparatively definite in the periodical classification of Buddhist art and eminent in the style of a Buddhist image. While Buddhist art of Unified Silla handled in this study mainly had close relation to the art style of Tang(唐) in the ancient China, it received the foreign cultures from the western countries and India by direct or indirect contacts. Therefore, the international inclination of Buddhist art in Korea, China and Japan, from the end of the seventh century to the mid-eighth century, had been shown more remarkably than in any other times. Here I divide this period into three parts in order to observe on the Buddga's costumes of Unified Silla Age. The features of each period is that : 1> the first period The first period ranges from immediately after Silla's unification to the end of the seventh century. The features of Buddha's costumes in this period were little removed from those of the period of the three Kingdoms such as thick Kasa, thick folds of "U" shape, symmetrical folds in a costume. But we can also find the new style in which clothes have drooped fold of manifold semicircle in shape. So, the first period was characterized in the mixture of the traditional style and the foreign style in the appearance of clothes. 2> the second period The second period is during about one century of the eighth century. During this period Silla's way of art was influenced by that of Tang(唐) in china and come to maturity in the art of sculpture with deep faith, Finally Silla had enjoyed the golden age of the art of sculpture. The method of expression in Buddha's costumes also broke from the ancient conventional style and got realistic and refined features of Silla's art. We can also find that the front skirt of Kasa in dress bottom included the new style in which it was cut as a "V" shape besides the horizontally cut style as shown till now. 3> the third period It is the end of Unified Silla ranged from the ninth century to the beginning of the tenth century. In this period the art of Buddhist statue was about to decline gradually from the mid-eighth century, the acme of Buddhist art's prosperity. This degeneration also had great influence on the style of Buddha's costumes, so that the style became formal and schematized. Now, we can summarize the characteristics of the popular style of Buddha's costumes in the times of Unified Silla. First, the styles of Buddhist statue's clothes were more in dress method of put on right and left shoulder than in dress method of put on left shoulder. Second, the style of King Asoka's statues and King Udyana's statues in the folds of clothes were so popular that they became the main current during the eighth century. However, from the beginning of the ninth century, the appearances of folds were formal and schematized with compact and parallel folds which are formally expressed. It is true that the scientists who study dress and its ornaments have left Buddha's costumes out of account due to the peculiarity of Buddha's costumes, whereas there have been more studies on Buddha's costumes on the historical point of art. I hope that with this study as a momentum, new studies on Buddha's costumes will be continued on the historical point of dress and its ornaments as well as that of art.

N値에 따른 地盤評價에 關한 硏究

In this paper, parameters of soil which are estimated with N-value and the results from laboratory test with the sample in construntion field are compared and analyzed. As a result, modification methods caused by existed weight is nearly same with the Equation of Liao & Whitman. Under same existed weight, the difference of N'/N is 0.9~2.1 in the Equation of Peck & Bazzaraa and Gibbs & Holtz. The Equation of O-Ja-Ki (&?'§) is more accurate with average value than any other equations in estimating a angle of internal friction of sand. The result of laboratory test is similar to the Equation of terzaghi & Peck. When unconfined compression strength of clay is estimated, the equation, q_(u) ≒ N/0.722, may represent many suggested equations. Standard Penetration Test is one of the most popular method to estimate parameters of soil because of its simplicity. Correlation between N-value and parameters of soil has been studied by many people but the absurd is still remain and we can face it on the construction field. Therefore field investigation and understanding about N-value are required when engineers estimate parameters of soil with N-value. There should be more study to get high accuracy of N-value and trustable parameters of soil.

To investigate the effect and mechanism of caffeine on endurance exercise, two experiments were performed. First, to test caffeine effect on aerobic exercise, 200-300g Sprague-Dawley rats were used and three groups, control group, low caffeine injection group and high caffeine injection group, were divided. Blood smpling by heart puncture were done at rest, after 30 min treadmill exercise, and after maximal exercise. Blood glucose, free fatty acid concentration were detected and following results were obtained. Glucose concentration showed significant difference between groups(p=0.0305) and also significant changes were exhibited between time(p=0.0004). Free fatty acid concentration had no difference between groups. but had significance between times(p=0.00065). Exercise endurance performance time showed significant difference(p=0.02350 in high caffeine injection group compared to control group. In this experiments, endurance exercise capacity was increased by caffeine injection. Therefore, second experiment was performed to investigate the effect of caffeine on ion current induced inhibitory amino acid neurotransmitter. GABA and glycine. Single periaqueductal gray neuron was acutely dissociated and nystatin perforated patch clamp was performed under voltage clamping condition. Caffeine evoked outward current in PAG neuron dose dependent manner. 1mM of caffeine application had no response. but 3mM caffeine evoked about 32.5±8.539pA outward ion current and 10mM caffeine evoked about 215.46±19.4pA outward current. 10^-2mM GABA activated Cl￣current and recorded by inward current. Caffeine inhibited GABA activated Cl￣ current concentration dependent manner. 10^-2mM of caffeine had no effect on 1-^-2mM of GABA response. but 10^-1mM caffeine inhibited GABA activated Cl￣ current about 5.74±2.13%, 1mM caffeine inhibited about 17.25±2.70%, 10mM caffeine inhibited GABA response about 45.31±7.71%. 10^-1mM of glycine activated Cl￣ current and also recorded by inward current. Caffeine inhibited glycine activated Cl￣ current concentration dependent manner. 10^-2mM caffeine decreased glycine activated Cl￣ current about 4.61±1.650%, 10^-1mM caffeine decreased about 6.49±2.24%, 1mM caffeine decreased about 26.82±4.27%, and 10mM caffeine decreased glycine response about 94.47±1.39%. These results suggest that caffeine inhibite inhibitory amino acid, GABA and glycine, this response causes excitation of CNS and this seems to be the basic mechanism of increasing effect to aerobic exercise performance by caffeine.

如法衣에 관한 硏究(Ⅰ) : 袈裟色을 中心으로 focused on the colour of Kasa

安明淑,李春桂 한국의류학회 1989 한국의류학회지 Vol.13 No.3

The purpose of this study was to investigate the general Kasa. More specially, the objectives of the research was (a) to determine the reason why dyes the colour of kasa; (b) to examine the kinds of Kasa colour; (c) to provide the dyeing method of Kasa colour; (d) to clarify the prohibited colour and the permitted limit; and (e) to find which and why kasa colour in our country use. The reason why dyes the colour of Kasa are the following; (a) it differentiates between the white robe in the leading ascetic life of Buddhism at ones home and that of the entering the priesthood. (b) it protects the victim of robbery (c) it discards the attachment to the ownership (d) it lessens the burden of at alms. The kinds of Kasa's color consist of several one such as 靑(cheung), 黑(heuk), ??(chun), 木蘭(mokran), and so on. The three colour among them use as the colour of kasa in the each vinaya pitaka. The dyeing method of kasa is composed of two ways; One is to dye the whole Kasa; the other is to dye the part of Kasa. Recently, in our country, the red which is the branch of kalasama is the leading colour of Kasa.

The present study was performed to investigate the ultrastructural changes of the type Ⅱ pneumocyte in the lung and that of the glomerulus in the kidney after carbon monoxide(CO) or hyperbaric oxygen (HBO) exposure. The male Sprague-Dawley rats, weighing about 200gm, were used as experimental animals. The animals were divided into CO exposure group, air exposure after CO exposure group, HBO exposure group and HBO exposure after CO exposure group. After single CO and HBO exposure (3790ppm), the specimen of lung and kidney were obtained. According to routine method, EM preparations were made and observed with electron microscope. The results obtained were as follows ; 1. Slight disruption of the mitochondrial membrane was observed in alveolar type Ⅱ pneumocyte, after single CO exposure. 2. In all experimental groups except CO exposure group, decrease in number and atropy of rough endoplasmic reticulum, disruption of double membrane and crista of mitochondria and vacuolar degeneration of lamellar bodies in alveolar type Ⅱ pneumocytes were observed. 3. In all experimental groups, fusion of the pedicles of podocytes, and obliterations of the endothelial fenestrations were observed. These results suggested that CO and HBO exposure may induced the ultrastructural damages in the alveolar type Ⅱ pneumocyte and the glomerulus.
