This article examined the applicability of spatial configuration to Escher's works through configurative logics and rules and studied the contrasting relations among the unit elements in Escher's works and their characteristics and the creative process of the characteristics. As the results of the study on the bases to maintain and create the partial elements revealed as the characteristics, it was shown that Escher's sequential transformative works demonstrated diverse expressive characteristics as a creative process of Inter-complementary contrasting relations based on the independence of the unit elements. It was also shown that the creative process of the unit elements was actualized through the maintenance base of the fixed and absolute characteristic as the logic for the creation and the creation base of the dynamic and relative characteristic. Therefore, it was interpreted that by applying the logics for creation to Escher's unit elements through the spatial interpretation of the maintenance base and the creation base as well as by configuring the units created in such a way according to the characteristics of Escher's works, spatial possibility canbe derived out from Escher's contrasting tessellation works. The process of spatial configuration is the process to make a balance between various conditions, artists own understanding of the space and his/her intention of the space. From this viewpoint, the logics for maintenance base and for creation base seem to have the potentiality as a spatial configuration to consistently meet the given conditions as well as to derive out novelty through the transformation to maintain the fixed and absolute condition(base) and the characteristics of the independent(additional) transformation arising together with the implicit relations among the transformative units.

Surface has been an important issue in contemporary architecture. That originates in structural freedom of surface since the end of modern architecture and the current stream of surface becoming an identity of building. Development of digital-media has brought a great change to our society in general. Digital-media is characterized by use of digital-information and interactive communication. Digital-media has been applied on surface in contemporary architecture lately. It is a purpose of the study to analyze the characteristics of digital-media application on surface based on the related characteristics of installation art. The categories and the contents for the frame of case analysis were arranged through document research. The foreign and domestic cases of digital-media application were analyzed based on the frame of analysis. Digital-media, which is installed on surface, is interacted with human and surroundings. It enhances emotional communication between human and architecture. Surface is not any more a simple fixture but an interactive creature. It makes surface more dynamically and fluidly that the course of light and human movement affect on digital-media. Surface itself is also turned into an object of art. It reflects the interweaving characteristics between contemporary architecture and installation art. It was analyzed through the study that emotional level of people is the important issue shared in digital-media application on surface and installation art. The complementary relationship between surface of contemporary architecture and installation art can be manipulated by the application of digital-media on surface.

Gamadi, a native rice cultivar from Nepal in which the panicle remains enclosed within its flag leaf sheath upto maturity, was crossed with different genetic marker testers of 12 linkage groups in order to analyze its linkage relationship. The results obtained from the experiment were summarized as follows: Normal segregations of all the genetic marker genes used in this experiment viz Cl, wx and Pla of linkage group I, Pn, Rd and Pub of linkage group III, and lg, g, Ps, gh, Hla, la, nl, bl, be and gl of linkage groups II, IV, V, VI, VII, VIII, IX, X, XI, and XII respectively confirmed the previous results, and also strongly indicated that the genetic constituent of the Gamadi and marker testers is same. 'Gamadiness' (the panicle enclosing character) was controlled by two complementary dominant genes with the segregation ratio of 9 Gamadi to 7 normal panicle-exserting types. These genes have been temporarily proposed as G-a and G-b for gamadiness. G-a gene was found to be linked with the neckleaf gene (nl) of linkage group Ⅸ with the crossover value of 0.3733$\pm$0.027. G-b gene appeared to be associated with the brittle culm gene (bc) of the linkage group XI with the crossover value of 0.2725$\pm$0.061.TEX>0.061.

This study reviewed useful aspects of the intraoperative transesophageal echocardiography among the patients in whom heart surgery were undertaken between January 1996 and July 1996 at St.Pauls hospital, Medical College of Catholic University, Seoul, Korea. During that period, 61 patients were operated on because of valvular heart disease(25 patients), coronary artery disease(22 patients), congenital heart disease(13 patients), and combined coronary artery disease and valvular heart disease(1 patient). Two patients(1 redo-VSD and 1 valvular heart diease) needed repeated aortic cross clamping and complementary procedures because of incomplete initial procedures. There was no incidence of air embolism. We could observe significant relationship of cardiac output monitoring methods either by thermodilution technique and transesophageal echocardiography by linear regression analysis(p<0.001). We tested myocardial response(percentage of systolic wall thickness, PSWT) with low dose dobutamine challenge to predict post-CABG myocardial perfusion. And the test showed statistically significant resp.onse(sensitivity 76%, specificity 94.7%, positive predictive value 95%, negative predictive value 75%). These results suggest that cardiac surgeon could draw more benefits by intraoperative transesophageal echocardiography.

This study is aimed at identifying the relationship of transit accessibility types to its related travel frequency in the Seoul metropolitan area. A multi-level poisson regression model is employed after categorizing transit accessibility into 18 types based on locations of residential and work workplace. Analysis results offer three policy implications in improving transit use in the Seoul metropolitan area. First, increase in transit ridership can be more effectively attained when policies concerning both competitive and complementary relationships between bus and rail transit are incorporated. Second, transfer system needs to be focused on such two modal perspectives as one travels from Seoul to suburban area and residential areas given the fact that walking accessibility to bus transit is good but that to rail transit is poor. Third, it is more effective to emphasize rail transit priority rather than bus transit, especially for the travel from suburban area to the city of Seoul in order to increase transit ridership.

Seasonal ginsenoside flux in the leaves of 5-year-old Panax ginseng was analyzed from the field-grown ginseng, for the first time, to study possible biosynthesis and translocation of ginsenosides. The concentrations of nine major ginsenosides, Rg1, Re, Rh1, Rg2, R-Rh1, Rb1, Rc, Rb2, and Rd, were determined by UHPLC during the growth in between April and November. It was confirmed total ginsenoside content in the dried ginseng leaves was much higher than the roots by several folds whereas the composition of ginsenosides was different from the roots. The ginsenoside flux was affected by ginseng growth. It quickly increased to 10.99±0.15 (dry wt%) in April and dropped to 6.41±0.14% in May. Then, it slowly increased to 9.71±0.14% in August and maintained until October. Ginsenoside Re was most abundant in the leaf of P. ginseng, followed by Rd and Rg1. Ginsenosides Rf and Ro were not detected from the leaf. When compared to the previously reported root data, ginsenosides in the leaf appeared to be translocated to the root, especially in the early vegetative stage even though the metabolite translocated cannot be specified. The flux of ginsenoside R-Rh1 was similar to the other (20S)-PPT ginsenosides. When the compositional changes of each ginsenoside in the leaf was analyzed, complementary relationship was observed from ginsenoside Rg1 and Re, as well as from ginsenoside Rd and Rb1+Rc. Accordingly, ginsenoside Re in the leaf was proposed to be synthesized from ginsenoside Rg1. Similarly, ginsenosides Rb1 and Rc were proposed to be synthesized from Rd.

This paper aims to explain the changes of social spatiality in rural areas as seen on a sloping scale in reference of population structure and utilization of territorial assets. Guessing from the population characteristics of rural communities and farming activities in Hwangsan village of Uichon-Myeon, Geochang-Gun and Hanam village of Chogye-Myeon, Hapchon-Gun, it will become a society characterized by super-aged intensification and large-scale crop cultivation. Deokgok-Myeon and Yulji village of Hapchon-Gun are required to intake outside residents. They have to understand the complementary cooperation and become conscious of the relationship between existing residents and relocated people in Yudong village of Yokji-Myeon, Tonyoung-Si. Due to a decreasing population and the phenomena of the 'super-aged', the efforts to revive the spatial function as a living and working space while utilizing territorial assets could be challenged in these case study regions.

The Government provides a financial assistance to stimulate firm R&D and innovation activities. Previous papers on the impact of public subsidies on firm R&D investments mainly had a focus on an individual policy tool regardless of potential impacts of other policy instruments. This study addresses this gap by examining the effects of policy mix regarding a subsidy and a tax credit. The empirical analyses from fixed effect model using Survey on Technology of SMEs 2015-2017 revealed valuable points. First, policy mix induces more R&D investment of SMEs, which in turn, shows a complementary relationship between two instruments. Second, even if impact of tax credit controlled, subsidy is positively associated with SMEs R&D investment. These findings justify policy mix interventions to promote SME R&D activity. Moreover, grants can be applied as a more useful policy tool for SMEs that are constrained by resources and capabilities.
