The purpose of this study is to develop the teaching competency tool of university teachers with responsibility for college education and analyze the need for change. We have developed teaching competency to strengthen the competencies required for university professors' responsibilities and community activities in and out of universities and the contents validity was examined from 24 experts. The developed tools were used to diagnose the 83 teachers of K university in Chungcheongnam-do, and to derive basic competence, educational practice competence, and community competence through exploratory factor analysis and confirmatory factor analysis. The teaching competencies include 'Understanding of college education', 'Educational philosophy and attitude', 'Teacher attitude', 'Analysis design', 'Instruction execution', 'Guidance management', 'Evaluation feedback', 'Academic convergence', 'Sympathy learning culture', and 'Global sharing'. The results of the paired t-test and the analysis of the need for change through the analysis of Borich coefficient analysis were as follows: Understanding of university education (4th rank), analysis design (5th rank), instruction execution(2nd rank), empathy learning culture (1st rank), and global sharing (3rd rank). The competence of university teachers is not only the ability to practice teaching, but also the ability to understand university education and to empathize and share with the members of the university community. In the future, the university should actively develop and provide ongoing support programs to strengthen the capacity of professors.

In this study, a total of more than 1,000 bacteria, including 739 species of aerobic bacteria, 80 species of urease producing bacteria and 303 species of photosynthetic bacteria, were isolated from red-pepper field soils located in the Gyeongsan Province of the Republic of Korea. Amongst these, 158 species of aerobic bacteria, 70 species of urease producing bacteria and 228 species of photosynthetic bacteria were found to be auxin producing soil bacteria through quantification analysis with the Salkowski test. The latter groupings were then tested for antifungal activities to ${\beta}$-Glucanase and siderophore using CMC congo red agar and CAS blue agar media. In addition, the selected strains were examined for antifungal activity against various phytopathogenic fungi on PDN agar media. Six strains; BCB14, BCB17, C10, HA46, HA143, and HJ5, were noted for their ability to both produce auxin and act as antifungal substances. 16S rDNA sequence comparison analyses of these six strains identified them as Bacillus subtilis BCB14, B. methylotrophicus BCB17, B. methylotrophicus C10, B. sonorensis HA46, B. subtilis HA143, and B. safensis HJ5.

This study was carried out to prove the factor properties of the soil affected by a forest fire through the physical and chemical analysis and the data from the conclusion of those analysis are applied to the development of technics that reduces a forest fire-induced 2nd damage. The forest fire was in December 2000 at Gangreung city and Donghae city, Gangwon provinces, Korea. Soil samples were collected at upper layers (0-5 cm) and bottom layers (5-40 cm) in November 2001 from the burned and control sites. Values of pH in burned soils of the upper layers affected by forest fire are higher than those in control soils. Both the fragments of fire-burned plant and differences of geological properties are resulted in a class of soil. Contents of organic matters in burned soils are higher than those in control soils, exceptionally the contents of organic matters in burned soils that contain coaly shale are lower than those in control soils. Weathering indices in burned soils are higher than those in control soils and it concerned with loss of soil. Iron ions Fe(Fe$^{2+}$ or Fe$^{3+}$) are easily extracted from the burned soils by rainfall, but Mn ions are straightly exist in the burned soils by physiochemical adsorption of colloid. Through the sequential extraction in the burned soils and control soils, we are certificate the extraction of Fe ions and the disturbance of Mn ions from the burned soils. As a consequence of factor analysis in burned soil and control soil, we are certificate that the influence of forest fire results in a disturbance of positive correlation factors.

Non-conventional resource and alternative energy were researched for predicting oil peak. In this study, one of many non-conventional resources, specifically oil-sands, was investigated due to the increasing interest of oil-sands plant modularization in permaforst areas for reducing the construction periods through modular transportation while limiting local construction workers. Hence, tehcnological trends were analyzed for oil-sand plant modularization. Data used were between 1994 and 2015 for patent analysis while targets included Korea, US, Japan, Europe and Canada. Technology classification system consisted of mining, steam assisted gravity drainage(SAGD), separation/upgrading/tailors ponds, module design/packaging, module transportation and material/maintenance. Result of patent analysis, patent application accounts 89% in US and Canada. The main competitive companies were Shell, Suncor and Exxon-mobil. Unlike other oil developments, oil-sands have a long-term stable production characteristic, hence, it is important to ensure the competitiveness of oil-sands for obtaining a patent in the long run.

In the past few decades, polymeric membrane has played an important role in gas separation applications. For the separation of $CO_2$, one of greenhouse gases, high permselectivity, long-term stability and scale-up are needed. However, conventional polymeric membranes have shown a trade-off relation between permeability and selectivity while inorganic materials are highly permeable but expensive. Mixed matrix membranes (MMMs) combining the advantages of both polymeric and inorganic materials have become a possible breakthrough for the next-generation gas separation membranes. The MMMs could be either symmetric or asymmetric but the latter is more preferred to improve the permeance. Important factors influencing the MMM fabrication include homogeneous distribution of inorganic particles and good interfacial contact between inorganic filler and organic matrix. Recently, metal organic frameworks (MOFs) have received much attention as a new class of porous crystalline materials and a potential candidate for $CO_2$ separation. Zeolitic imidazolate frameworks (ZIFs), a sub-branch of MOFs, are the most widely used in MMMs due to small particle size and appropriate pore size for $CO_2$ separation. One of the major issues associated with the incorporation of porous particles in a polymeric membrane is to control the microstructure of the porous particle materials such as particle size, orientation, and boundary conditions etc. In this review, major challenges surrounding MMMs and the strategies to tackle these challenges are given in detail.

This study aims to develop a distress prediction model, in order to evaluate the distress prediction power for first-class hotels and to calculate the average financial ratio in the Seoul area by using the financial ratios of hotels in 2015. The sample data was collected from 19 first-class hotels in Seoul and the financial ratios extracted from 14 of these 19 hotels. The results show firstly that the seven financial ratios, viz. the current ratio, total borrowings and bonds payable to total assets, interest coverage ratio to operating income, operating income to sales, net income to stockholders' equity, ratio of cash flows from operating activities to sales and total assets turnover, enable the top-level corporations to be discriminated from the failed corporations and, secondly, by using these seven financial ratios, a discriminant function which classifies the corporations into top-level and failed ones is estimated by linear multiple discriminant analysis. The accuracy of prediction of this discriminant capability turned out to be 87.9%. The accuracy of the estimates obtained by discriminant analysis indicates that the distress prediction model's distress prediction power is 78.95%. According to the analysis results, hotel management groups which administrate low level corporations need to focus on the classification of these seven financial ratios. Furthermore, hotel corporations have very different financial structures and failure prediction indicators from other industries. In accordance with this finding, for the development of credit evaluation systems for such hotel corporations, there is a need for systems to be developed that reflect hotel corporations' financial features.

This is a study on the flower pattern artwork of the west wall of the Jagyeongjeon in Gyeongbokgung to find out the type of plants and flowers represented and their symbolism. The research was conducted from July 2010 to March 2011 and the artwork classified on the basis of its horticultural traits. A number was assigned to each pattern for analysis: No. 1 is Prunus mume, No. 2 is Prunus persica, No. 3 is Paeonia suffruticosa, No. 4 is Punica granatum, No. 5 and 6 is Dendranthema grandiflora, No. 7 is Rhododendron mucronu and No. 8 is Phyllostachys bambusoides. These 8 flower patterns symbolize longevity and fecundity and their presense around the Jagyeongjeon helped to bestow good fortune on the royal family so that they might live long lives and bear many children. 4 artworks symbolize longevity, 2 artworks symbolize integrity and 1 artwork symbolizes wealth and happiness. There is also symbolism of the need to have constancy in a royal household even during secular change. Out of the 8 artworks, the imagery of a bird and a moon is represented only once, but the image of a butterfly is represented five times in the surrounding elements. The bird and butterfly symbolise freedom and happiness from free love. Women in the palace are like a butterfly wanted to be like love as a freedom and have a free and open relationship like a butterfly. But a harmonious relationship between the royal family wanted to have a symbolic meaning that could be seen of the symbolistic. Based on the "Yangwhasorok"only plants with the highest values, from the 1st and 2nd grades, were used in the artwork of the west wall of the Jagyeongjeon.

In order to investigate the application of bamboo in various ways in floral designs, we analyzed 108 bamboo items from the monthly magazine 'Fleur' and from the International Flower Contest held from 2001 to 2006. We analyzed the frequency of usage of bamboos by the used parts, kind of design, type of design, and arrangement method in the design work. In terms of the used parts of the bamboo, stems took 90% of the whole work. Among the 77 designs that used stems, excluding the 20 work items presented in the International Flower Contest which has been held in April, number of the bamboo work items peaked at the beginning of the year in January and February, and during summer (July and August). Upon analyzing the type of stems that were used in the 97 works, 63% of the works used bamboo in natural state, but not processed. 48% of the works used the vertical-parallel method among the arrangement methods. Other categorized works were rounded works that were not included in the vertical, horizontal or diagonal mathod. More than 50% of the works, including the table decoration, used space decoration. Among the types of work design that used bamboo as material, 64% were decorative type, 30% graphic type, and 4% formal-linear type.

In both the East and the West, the most classical question in classical philosophy was, "What is truly a human virtue and a good man?" A good man realized a human virtue. A good man was composed of mind and body. The question is harmony of mind and body. This article aims to articulate the terms related on Mind and Body in Confucian analects. We analyzed the terms related to Mind (mind, mind-heart, human nature, feeling, will etc) and we analyzed the terms related to Body (body, self, ki etc). Confucius's Theory of Mind and Body Relation focus on self-cultivation and revelation of universal virtue. Chu-his(1130-1200)'s commentary of the terms related on Mind and Body in Confucian analects is based on Heaven's principle vs. man's desire. He advanced the theory of the human mind and moral mind on the bases of Li-Ki. Dasan(1762-1836) deconstructs the mind-law of 16 characters and the theory of Li-KI. He argues that the human mind and moral mind coexist as a servant and a master. Dasan insists that the human mind is controlled by the moral mind but he wants to reconstruct the new theory of mind-body, mind-heart.
