As the change of information and digital technology progresses, ubiquitous space is attracting attention as a new space concept in which the physical and digital spaces are connected to each other. As its meaning in latin itself - 'there exist everywhere at the same time'- implies, however, the ubiquitous space has been mostly discussed in a non-physical aspect, such as in a technological area, rather than its physical intrinsic property until now. Although theories regarding a ubiquitous city have been rarity suggested, in most cases, technological aspects such as the systemization or networking of individual information service have been the focus. However, one of the intentions induced in the concept that scholars including Mark weiser and Sakamura Ken introduced was to place humans in the center of the space in which the technology has been placed instead of humans. For this purpose, the renovation of human interface must be required. As technology develops, the achievement of ubiquitous space may be possible, and efforts to apply this to real space are making an appearance. The examples of the present research are the spaces that have a characteristic of the laboratory separated from life in the city, and the construct scale is in the level of an individual facility; therefore, further studies should functionally and spaciously connect all subjects existing in space and effectively relate this to real world. The present research is intended to demonstrate the investigation on several projects that are currently underway and the developmental direction of new, ubiquitous space.

Apoptosis is the ability of cells to self-destruct by the activation of an intrinsic cellular suicide program when the cells are no longer needed or when they are seriously damaged. Morphologically, apoptosis is characterized by the appearance of membrane blebbing, cell shrinkage, chromatin condensation, DNA cleavage, and the fragmentation of the cell membrane-bound apoptotic bodies. Siegesbeckia glabrescens Makino (Siegesbeckiae Herba, SG) has been widely used as treatments for arthritis, and fever, as well as detoxification properties. The present studies were undertaken to evaluate if SG has an anti-apoptotic property. Cell viability was measured by XTT and tryphan blue stain. Morphological characteristic of human aortic smooth muscle cells(HASMC) were visualized with a phase-contrast microscope. SG significantly reduced HASMC, but not human umbilical vein endothelial cell(HUVEC), viability in a dose-dependent manner. Confluent untreated cells at 24hrs showed normal morphology, flat with a uniform polygonal shape. SG-treated cells (0.5㎎/㎖) at 24hrs showed apoptotic morphology. Cells became irregular with elongated lamellipodia, and exhibited condensed chromatin in nuclei with occasional endoucleation. There was an increase in the number of apoptotic cells rounding-up and being detached from the substrate. TUNEL staining of SG-treated cells showed dark-brown stains in nuclei and cytosol. Caspases are central components of the machinery responsible for apoptosis and are generally divided into two categories; the initiator caspases, which include caspases-2,-8,-9, and -10, and the effector caspases, which include caspases-3,-6, and -7. SG decreased anti-caspase-3 protein expression, which means activation of caspases-3 activity. It has been reported that there is a link between NO formation and apoptosis. NO production was accelerated by SG treatment in HASMC. L-NNA, NOS inhibitor, inhibited SG-induced apoptosis. These results, therefore, indicated that both caspases-3 and NO production are involved in apoptosis in smooth muscle cells. According to these results, SG may have a potential effect in the treatment of hypertensive atherosclerosis.
First of all, What was the modeling technique used to model 3D-Game character? It's a technique developed along several years, by experience... here is the bases Low polygons characters I always work in low polygon for two reasons -You can easily modify a low-poly character, change shapes, make morph for facial expressions etc -You can easily animate a low-poly character When the modeling is finished, Second, In these days, Computer hardware technologies have been bring about that expansion of various 3D digital motion pictured information and development. 3D digital techniques can be used to be diversity in Animation, Virtual-Reality, Movie, Advertisement, Game and so on. Besides, as computing power has been better and higher, the development of 3D Animations and Character are required gradually. In order to satisfy the requirement, Research about how to make 3D Game modeling that represents Character's emotions, sensibilities, is beginning to set its appearance. 3D characters in 3D Games are the core for the communications of emotion and the informations through their facial expression and characteristic motions, Sounds to Users. All concerning about 3D motion and facial expression are getting higher with extension of frequency in use. Therefore, in this study we suggest the effective method of modeling for 3D character and which are based on 2D Graphics.
Through the questionaire inquiry from April 1st to 10th, 1974 with 393 students in Woonho, Saekwang junior and senior highschool and Daisung, Ilshin girls' junior and senior highschool in Chungju, Choong Cheong Buk Do, I surveyed the general circumstances of students and their unbalanced diet on total 199 foods and causes of the unbalanced diet and regard the 21 boys and 29 girls who don't like to eat more than 30 foods from the given 47 protein-foods which are needed by students who are now in the stage of growth. This study is concerned with their circumstances and the causes of their ill habit of eating. 1) As to their distribution of age, 14 and 18 year old boys were six (28.5%), 11 and 13 year old girls were eleven (38.1%). In the survey on their height, 6 boys (28.5) were from 146 cm to 150 cm and 11 girls (38.1%) were from 146 cm to 150 cm. On the weight, 7 boys were from 36 kg to 40 kg(33.7%), 10 girls were from 36 kg to 40 kg (34.0%). We can see that ill habiters of eating were more weaker than other students from this data. 2) In the survey of educational level of their housewive it was found that number of graduates of the primary school is thirty (60.0%). So we can derive the fact that they don't make any variety in their daily table for their family. 3) As to their living standard, 19 boys (90.4%) and 27 girls (93.3%) belong to the middle class, low and high class were a little. This indicates the general living standard if Korea, because in common sence we regard the riches are the more ill habiters of eating. 4) 8 boys (36.8%) and 8 girls (26.8%) were the first children in their homes. This indicates the fact that housewive happen to make the first child as the ill habiter of eating because their lack of experience to give various food for their children. As to the survey on their infant nutriments, 41 students (80.2%) were fed by mother's milk. 5) Upon the causes of the unbalanced diet on a certain food, 34 boys (82.7%) and 45 girls (64.6%) were because of appearing to that food, 10 boys (40.8%) and 18 girls (61.5%) were because of the characteristic fragrance, 11 boys (52.4%) and 17 girls (58.1%) were because they have never eated that food till now, 34 boys (19.3%) and 5 girls (17.0%) were because of the bad appearance of the food. So housewive should study various ways of cooking daily meals at home and try to give their children who are in the stage of growth to be able to eat wider kinds of foods for the improvement of health.

Cymbidium 'Orange Bowl' (Lucky Rainbow 'Randevous' ${\times}$ 'Eastern Star') was developed from a cross between hybrids at the National Institute of Horticultural & Herbal Science, Rural Development Administration in 2006. A cross was made between the pink colored flower C. Lucky Rainbow 'Randevous' as maternal line and pure yellow colored flower, C. 'Eastern Star' as paternal line in 1995. The seed germination, cultivation, selection, and characteristic trials were conducted from 1996 to 2006. The line was named as Wongyo F1-18 and phenotype was characterized in 2006 as a new 'Orange Bowl'. The 'Orange Bowl' has having light yellow basal color (RHS, YO21D) and orange line (RHS, OR30B) on both of sepal and petal with red lip (RHS, OR30B). 'Orange Bowl' has about 10.9 flowers per flower stalk and flower size of 7.4 cm. General appearance of the petals and sepals is slightly incurved shape. The plant size is intermediate having erect peduncle. Blooming is started from the late of January (mid winter) under optimal culture condition. Leaf attitude and twisting is half- erect and very weak respectively. This hybrid has attractive floral arrangement, long flower stalk (71.8 cm) and vigorous growth. We expect that 'Orange bowl' has a great potential for exporting to Chinese market.
In this study, gelatin binding ability was increased by adding cross linking agent to improve adhesive characteristic of animal glue. Animal glue added genipin measured gel strength and viscosity, the structural analysis, the color retention degree, elution degree, and rupture strength. And the water resistance and ultraviolet light resistance with the addition of genipin were compared. As a result of the study, the gel strength and viscosity increased with the amount of genipin. As a result of the structural analysis, in gelatin, the absorption peak of the triple structure of collagen structurally stabilized was observed. As a result of the color retention degree, the film was observed because of the lowered brightness. The amount of elution glue was increased with addition of genipin at $50^{\circ}C$ distilled water condition and rupture strength has increased with the amount of genipin. In the water resistance and light fastness, there was no appearance before and after deterioration due to the addition of genipin. Based on the results of this study, it confirmed the adhesive characteristics of animal glue added genipin and examined the experimental method applicable for animal glue. After the addition of genipin, flexibility, re-solving, adhesive force, and curing speed, which are unique characteristics of glue, can be improved without disappearing, so it is expected that it will be applicable to production of animal glue and conservation of cultural heritage when homogeneous glue is secured.
Purpose : The purpose of this study was to examine the clinical courses and long-term outcomes of children with Allagille syndrome in Korea, and to evaluate the prognostic potentials of identified variables. Methods : We reviewed the clinical manifestations and outcomes of 30 children with Alagille syndrome, investigated from 1984 to 2006 until the end of this study (defined as death or last visit; mean follow-up : 5 years). Results : Cholestasis occurred in 100 percent, cardiovascular abnormalities in 83.3 percent, butterfly vertebrae in 30.0 percent, posterior embryotoxon in 43.3 percent, and a characteristic facial appearance in 100 percent. At study conclusion, of these 30 patients, eight had died (26.7 percent); six related to Alagille syndrome. Five patients died of a liver disease complication. Liver transplantation was carried out in five of the 30 patients (16.7 percent) and one of these died due to hyperacute rejection. At age two, cholestasis improved in 17 of the 30 patients. Those who had severe cholestasis at 2 years of age tended to have a complication, such as liver cirrhosis or liver transplantation, or to have died. Conclusion : Hepatic complications account for the most mortalities in patients with Alagille syndrome. Careful and complete assessments should be made in children who have cholestasis at 2 years of age. Further investigations of more cases are required.

The interfacial adhesion strength is very important in $SiO_x$ deposited PC film for the barrier enhanced polycarbonate (PC) flexible substrate. In this study, PC films were treated by undercoating, UV/$O_3$ and low temperature plasma and then the effect of physical and chemical surface modifications on the interfacial adhesion strength between PC film and $SiO_x$ barrier layer were studied. It was found that untreated PC film shows significantly low interfacial adhesion strength due to the smooth surface and low surface free energy of PC. Low temperature plasma treatments resulted in the increase of both surface roughness and surface free energy due to etching and the appearance of polar molecules on the PC surface. However, UV/$O_3$ treatment only shows the increase of surface free energy by developed polar molecules on the surface. These surface modifications caused the enhancement of surface interfacial strength between PC film and $SiO_x$ barrier. In the case of undercoating, it was found that the increase of surface interfacial strength was achieved by adhesion between various acrylic acid on acrylate coated surface and $SiO_x$ without increase of polar surface energy. In addition, the barrier property is also improved by organic-inorganic hybrid multilayer structure.

The purpose of this study was to search available resources for new natural colorants. The extraction efficiency of colorants from black cowpea seed coats and their storage stability were examined according to the various extraction and storage conditions in this study. The results obtained were as follows: the optical density (O.D.) values of the extracted colorants increased with increasing extract time and temperature. Extraction at pH 4 was seen to be the most efficient among the various pH conditions. The color of the extract solutions were seen to change with variation in pH, for example, anthocyanins display color changes from orange-red, to orange, to blue, to greenish-blue at pH 3.0, 4.0-6.0, 7.0 and 9.0-11.0, respectively. The color changes of the extract solutions over various storage periods were determined using UV/Vis spectra these color changes indicate characteristic absorption patterns and a discoloration index which indicates the rate of absorbance (532 nm/454 nm). Methionine addition influenced the storage stability of the colorant solutions and this addition led to better storage stability than non-addition. In paper chromatography of juice extracted colorant, a long stripe was seen on development. Among three colorants obtained via paper chromatography according to development rate, at least two different colorants were mixed indicated by the appearance, or not, of a shoulder at 552 nm depending on the extent of development.

Last March, the world Go competition between AlphaGo, AI Go program developed by Google Deep Mind and professional Go player Lee Sedol has shown us that the 4th industrial revolution using AI has come close. Especially, there ar many system combined with AI hae been developing including program for researching legal information, system for expecting jurisdiction, and processing big data, there is saying that even AI legal person is ready for its appearance. As legal field is mostly based on text-based document, such characteristic makes it easier to adopt artificial intelligence technology. When a legal person receives a case, the first thing to do is searching for legal information and judical precedent, which is the one of the strength of AI. It is very difficult for a human being to utilize a flow of legal knowledge and figures by analyzing them but for AI, this is nothing but a simple job. The ability of AI searching for regulation, precedent, and literature related to legal issue is way over our expectation. AI is evaluated to be able to review 1 billion pages of legal document per second and many people agree that lot of legal job will be replaced by AI. Along with development of AI service, legal service is becoming more advanced and if it devotes to ethical solving of legal issues, which is the final goal, not only the legal field but also it will help to gain nation's trust. If nations start to trust the legal service, it would never be completely replaced by AI. What is more, if it keeps offering advanced, ethical, and quick legal service, value of law devoting to the society will increase and finally, will make contribution to the nation. In this time where we have to compete with AI, we should try hard to increase value of traditional legal service provided by human. In the future, priority of good legal person will be his/her ability to use AI. The only field left to human will be understanding and recovering emotion of human caused by legal problem, which cannot be done by AI's controlling function. Then, what would be the attitude of legal people in this period? It would be to learn the new technology and applying in the field rather than going against it, this will be the way to survive in this new AI period.
