To define an interface in a conventional level-set method, an analytical function must be revealed for an interfacial geometry. However, it is not always possible to define a functional form of level sets when interfaces become complex in a Cartesian coordinate system. To overcome this difficulty, we have developed a new level-set formalism that discriminates the interior from the exterior of a CAD modeled interface by parameterizing the stereolithography (STL) file format. The work outlined here confirms the accuracy and scalability of the hydrodynamic reactive solver that utilizes the new level set concept through a series of tests. In particular, the complex interaction between shock and geometrical confinements towards deflagration-to-detonation transition is numerically investigated. Also, a process of flame spreading and damages caused by point source detonation in a real-sized plant facility have been simulated to confirm the validity of the new method built for reactive hydrodynamic simulation in any complex three-dimensional geometries.

Objectives : The objective of this study is the Basic research for mind and body cure protocol construction through the Sim(心) study at Buddhism Medicine, Constitutional Medicine, and Oriental Medicine. Methods : 1. The Sim(心) in Buddhism is a target of spiritual culture and subjective awareness of An ascetic person in interior psychology. In this research, the Sim(心) has been modified within a concept of Early Buddhism and You-sic in order to have medical logicality. 2. Since the study deep into Sim(心) within Confucianism has various aspects, each Confucian's theory argument or era. We limited the significance of the Sim(心) to be associated with the category of the Sim(心) in Sasang Constitutional Medicine which is a product of practical Confucianism. 3. The criteria of debate for the Sim(心) is based on the "Hwang-je-nae-gyoung", because "Hwang-je-nae-gyoung" is founded to definite the term regarding spirit or mind in Oriental medicine Results : 1. "Hwang-je-nae-gyoung" which came from thought of You-Sic, thought of Taoism, and Early Buddhism becomes the theoretical basis for the Sim(心) in Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine. 2. The Sim(心) in the mind psychology of Buddhism Medicine, Sasang Constitutional Medicine, and Oriental Medicine has active aspects. but the visual thing // There are visual aspects being contrasted with 'Sim(心)' of mind psychology and aspects of activity in Buddhism medicine, Sasang constitutional Medicine and Oriental Medicine; which are 'Hrd', 'Hrdaya', 'four-large' 'five base', 'chin, chest, navel and abdomen', 'head, shoulder, waist and buttocks' consisting 'the body', and the heart and 'four interorgans' from the study of symbolical interorgans). In Buddhism Medicine, Sim(心)'s Epistemology is the most extensively understood fact about 'Sim(心)', and for Sasang Constitutional Medicine and Oriental Medicine. 'Sim(心)' is limited as an 'Element' that comprises the body. 3. The Functional area of the Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, Oriental Medicine is composed with 'consciousness(意識)' 'manas-vij_na(末那識)', '_aya-vij_na(阿賴耶識)', 'mind greed(心欲)', 'Li(理)' and 'Sin(神)', about the interpretive area of 'Sim(心)', 'Sin(神)' of Oriental medicine is the most comprehensive concept, and on the side of the depth of 'thinking' and 'consciousness', '_aya-vij_na(阿賴耶識)' from Buddhism Medicine in the key point. 4. The Sim(心) in the Buddhism Medicine, Sasang Constitutional Medicine, has the positive and negative aspects, such as the 'Dukkha(煩惱)' and A merciful heart or Human Sim(心) and Taoism Sim(心).

University campuses try to satisfy students' demands. Therefore, the physical environment of university campuses keeps changing. Due to the increasing the number of students and shortage of school building facilities, it is necessary to improve the facilities and create new space in the campus, in order to solve this problem and improve the universities. At the moment, the learning method of university students is evolving toward discussion sessions involving fellow students and presentations utilizing multimedia facilities. In response to these changes, a new type of independent space has appeared, which is called the Group Study Room. In this study, we analyze the spatial characteristics of the Group Study Room. Also, through an IPA(Importance Performance Analysis), this study tries to examine the relationship between the spatial characteristics and users' satisfaction. This analysis is expected to reveal the importance of the spatial characteristics of the group study rooms from the users' point of view. This research can be used for facility planning in universities in the future. The primary aim of this study is to analyze the physical environment of the Group Study Rooms of K university. The secondary aim of this study is to manifest the characteristics of these new learning spaces and to check the space elements of the group study rooms for the sake of efficient planning and management.

Background and Purpose Through ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, Dongmu Lee Je-ma supposed the minds of management for Sasang Constitutional Symptoms, which had been accomplished through several steps from his early writings to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. His basic minds of treatment for disease had been supposed early in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$ and ${\ulcorner}$Gyukchigo${\lrcorner}$, and had been completed to the Sasang Constitutional Symptoms and the minds of management for it, from ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894 to ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. In this paper, I tried to find the minds of treatment of ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$, through classifying and researching the early minds of treatment (presented in ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\ulcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$), and the latter minds of treatment (presented in ${\ulcorner}$Dongyi Soose Bowon${\ulcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901) Methods It was researched as bibliologically with his writings such as ${\ulcorner}$Gyojapyungseongjam${\lrcorner}$, ${\ulcorner}$Gyukchigo${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ written in 1894, ${\ulcorner}$Dongyi Soose Bowon${\lrcorner}$ published in 1901. Results and Conclusions The conclusions were as follows. 1. At early, Dongmu Lee Je-ma pursued the minds of treatment at the autonomous control through 'Acquaintance and Self-control' based on 'the Knowledge of Nature and Desire', so emphasized 'self-control' as important point in treatment. 2. From ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$, Dongmu summarized Sasang constitutional symptoms structurally in view of Morpho-imaginary. In ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun${\lcorner}$ and ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ written in 1894, It was described in view of small organ, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, suggested more updated in view of both large and small organ and to which added the concept of Hot and Cold. 3. Through reinterpreting the concept of interior and exterior disease in ${\ulcorner}$Sanghanrhon${\lcorner}$, the concept of Sasang constitutional symptoms had started as the minds of treatment for individual disease, but in ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, it was accomplished as the minds of broad management for Sasang Constitutional Symptoms. 4. In ${\ulcorner}$Dongyi Soose Bowon${\lcorner}$ published in 1901, the broad therapeutic prescriptions for management of Sasang constitutional symptoms were proposed newly, according to the accomplishment of Sasang constitutional symptomatic patterns, so these have different aims and are more important than that proposed previously. 5. The control in view of 'Knowledge and Deed' and the minds of management for Sasang constitutional symptoms are the minds and spirits for treantment and prevention against disease, which can maximize the power of autonomous self-treatment and manage all disease broadly.

The fresh eggs of African ostrich in Korea were used in this study to investigate their interior and exterior quality characteristics. In ostrich egg shape characteristics, long and short length were measured as 15.1~16.1 cm and 12.1~13.6 cm, respectively. The egg shape index was calculated as 81.0 and the egg shell showed a more g loss white in color than that of hen egg. Calculated breaking strength of egg shell and egg shell surface based on the equation were $41.155kg/cm^3$ and $804.7cm^2$, respectively. Average egg shell thickness including egg shell membrane was 1.89 mm and there are no differences among parts of the shell. The egg shell membrane thickness was 0.10 mm showing relatively thick in equator compared with that of blunt end. The ave rage number of egg shell pores was counted as $19.7/cm^2$ showing relatively high number of egg shell pores at point end and the total number of egg shell pores in an egg was estimated as 15,241. The relative port ion of each parts based on egg weight was estimated as 25.1% for egg yolk, 58.2% for egg white, 16.7% for egg shell and the ratio of egg yolk to egg white (Y/W) was 0.43. The average diameter and the ave rage height of ostrich egg white were 19.7 cm and 13.2 mm, respectively. Calculated the H.U (Haugh Unit) was -69.7 and the pH was 8.3. In ostrich egg yolk, the diameter, the height, the egg yolk index, and it's pH were calculated as 14.4 cm, 29.4 mm, 0.20, and 6.6, respectively. And the egg yolk color showed a more thin in yellow chroma compared with that of hen egg as due to it's thicker membrane.

This study investigates the hydraulic characteristics and the delta development processes in the improved-pneumatic-movable weir by considering the standing angle of the weir through laboratory experiments. The delta migration speed decreases rapidly with time. As the ratio of delta height to water depth increases, the dimensionless delta migration speed decreases at the delta point. Therefore, the water depth decreases as the delta height increases. Although the delta volume is large due to the effective height of the delta, the delta migration speed and sediment deposition decreases because of the backwater effect on the delta. On the same bed slope condition, the larger the weir height, the larger the delta volume and the ratio of delta height to delta front length is close to 1.0. The delta development could be suppressed when the weir is high. Therefore, the condition that the weir is high has the suppressing effect on the delta developments.

Carry over contamination has been reduced in some systems by flushing the internal and external surfaces of the sample probe with copious amount of diluent. It between specimens should be kept as small as possible. A built-in, continuous-flow wash reservoir, which allows the simultaneous washing of the interior and exterior of the syringe needles, addresses this issue. In addition, residual contamination can further be prevented through the use of efficient needle rinsing procedures. In discrete systems with disposable reaction vessels and measuring cuvets, any carry over is entirely caused by the pipetting system. In analyzers with reuseable cuvets or flow cells, carry over may arise at every point through which high samples pass sequentially. Therefore, disposable sample probe tips can eliminate both the contamination of one sample by another inside the probe and the carry over of in specimen into the specimen in the cup. The results of the applicative carry over experiment studied on 21 items for total protein (TP), albumin (ALB), total bilirubin (TB), alkaline phosphatase (ALP), aspratate aminotranferase (AST), alanine aminotranferase (ALT), gamma glutamyl transferase (GGT), creatinine kinase (CK), lactic dehydrogenase (LD), creatnine (CRE), blood urea nitrogen (BUN), uric acid (UA), total cholesterol (TC), triglyceride (TG), glucose (GLU), amylase (AMY), calcium (CA), inorganic phosphorus (IP), sodium (Na), potassium (K), chloride (CL) tests in chematology were as follows. Evaluation of process performance less than 1% in all tests was very good, but a percentage of ALB, TP, TB, ALP, CRE, UA, TC, GLU, AMY, IP, K, Na, and CL was 0%, implying no carry over. Other tests were ALT(-0.08%), GGT(-0.09%), CK(0.08%), LD(0.06%), BUN(0.12%), TG (-0.06%), and CA(0.89%).

For camera calibration, a checkerboard is generally used to determine the principal point, focal length, and lens distortions. The checkerboard has a planar and three-dimensional shape, and camera calibration parameters are affected by the size of the checkerboard, the placement of the target, and the number of target points. In this study, the accuracies of the types of checkerboards were compared using checkpoints for stereo camera calibration, and the purpose of this study was to propose the best performance checkerboard. The checkerboard with large flat shape showed comparatively high accuracy through comparison with the check points. However, due to the size of the checkerboard, it was inconvenient to move and rotate, and there was a disadvantage in that it was difficult to shoot so that the target points could all appear in the stereo camera. The checkerboard, which was manufactured in a small size in a flat shape, was easy to move and rotate but had the lowest three-dimensional accuracy. The checkerboard with targets with height values had the hassle of having to determine the three-dimensional coordinates of the target points by using observation equipment for camera calibration, but it was small in size, convenient to move and rotate, and showed the highest three-dimensional accuracy.

Three-yum and three-yang(三陰三陽) is the change state of yum-yang(陰陽) which is caused by six gi(六氣). They mean the flow of six gi(六氣) which exist throughout the viscera, the channel(經絡), and the skin. But it is not easy to understand the meaning because the contents of the attribute of three-yum and three-yang(三陰三陽), the bolt-leaf-hanges(關闔樞) theory and large or small of gi-blood(氣血多少) which is the main clue that explain it in ${\ll}$Somun(素問)${\gg}$ and ${\ll}$Yeongchu(靈樞)${\gg}$ don't coincide with each other. I, the writer, tried to understand the uncertain meaning and the contents which are written about three points above differently in each of the books that are ${\ll}$Somun(素問)${\gg}$ and ${\ll}$Yeongchu(靈樞)${\gg}$. So, from that the course that the book, ${\ll}$Huangjenegeong(黃帝內經)${\gg}$ is handed down is so relatively simple in a wood block-printed book, that the ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$ has less wong-words than the Somun(素問) and the Yeongchu(靈樞), and from that Yangshangsun(楊上善) wrote the note in the ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$ by royal order about 100 years former than Wangbing(王氷), as making projects of Yangshangsun(楊上善)'s note and the original of the ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$ which has relation to the yum-yang(陰陽) attribute of three-yum and three-yang(三陰三陽), the bolt-leaf-hanges(關闔樞) theory, and the large or small of gi-blood(氣血多少) and researching the Yangshangsun(楊上善)'s theory. The result is summarized like this. First, wherease the order of the change of three-yum and three-yang(三陰三陽) which is explained by Yangshangsun(楊上善) consider the change of yangi(陽氣) in body most important, the order of the change gaeggi(客氣)'s three-yum and three-yang(三陰三陽) considers chungi(天氣) most important, and the order of jugi(主氣)'s three-yum and three-yang(三陰三陽) considers jigi(地氣)'s change of ohaeng(五行) most important. If the order of change three-yum and three-yang(三陰三陽) in the ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$ is considered, each of taeyang(太陽) and soyum(少陰) are expressed as the base of yum-yang(陰陽) and yangmeong(陽明) and taeyum(太陰) are expressed as the palmy days of yum-yang(陰陽), soyang(少陽) and gyolyum(厥陰) are expressed as pacemaker(樞杻) which controls the change of yum-yang(陰陽). Thus, each has something in common that is fettered by the inside and outside. In the flow of channel(經絡), taeyang(太陽) and soyum(少陰) take charge of the behind of body, yangmeong(陽明) and taeyum(太陰) take charge of the front of body and soyang(少陽) and gyolyum(厥陰) take of the side of body. Second, in Yangshangsun(楊上善)'s bolt-leaf-hanges(關闔樞) theory, three-yum(三陰) is regarded as inside, three-yang(三陽) as outside, so when bolt, leaf and hanges fulfil their duties in inside and outside, the life(life force) is thought to be revealed normally. It is impossible to understand the bolt-leaf-hanges with the conception of the inside and outside which divide three-yum and three-yang(三陰三陽) into taeyang-soyum(太陽-少陰), yangmeong-taeyum(陽明-太陰), soyang-gyolyum(少陽-厥陰) according to yum-yang(陰陽) attribute, hence it need the special conception that is taeyang(太陽)-taeyum(太陰), yangmeong(陽明)-gyolyum(厥陰), soyang(少陽)-soyum(少陰) which center on their duties in inside and outside. In the denunciation of the word open(開) and bolt(關), because Yangshangsun(楊上善) said that the duities of taeyang(太陽) and taeyum(太陰) are shutter(閉禁), bolt(關) is coincided with that significance. Third, with explaining the large or small of gi-blood(氣血多少) of three-yum and three-yang(三陰三陽), Yangshangsun(楊上善) expressed the inside and outside either in the same way or differently. Because the inside and outside is interior of body and exterior of body, it is the explanation that is noticed by the fact that the property of large or small of gi-blood(氣血多少) is either able to be same or different. In this viewpoint, if we unite the contents about large or small of gi-blood(氣血多少) of ${\ll}$Somun(素問)${\gg}$, ${\ll}$Yeongchu(靈樞)${\gg}$, we will find that the descriptions of large or small of gi-blood(氣血多少) of three-yang(三陽) in ${\ll}$Somun(素問)${\gg}$ ${\ll}$Yeongchu(靈樞)${\gg}$ correspond with the ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$, but in three-yum(三陰), the contrary presentations exit. The reason is that large or small of gi-blood(氣血多少) of three-yum(三陰) isn't only expressed as che(體) in the point of che-yong(體用), but as a point of yong(用) that is a phenomenon. As researching the original of ${\ll}$Huangjenegeongtaeso(黃帝內經太素)${\gg}$ and Yangshangsun(楊上善)'s notes as a center about three problems that are yum-yang(陰陽) attribute, the bolt-leaf-hanges(關闔樞) and large or small of gi-blood(氣血多少) of three-yum and three-yang(三陰三陽), I, the writer, tried to explain the part which is written differently or has uncertain conception in the book ${\ll}$Somun(素問)${\gg}$ and the book ${\ll}$Yeongchu(靈樞)${\gg}$, but the concrete result of the work like this will be judged according to the question how many theories are correspondent with real presence at a sickbed. Hence, the work to veryfy the theories in the future will be left as assignment.
