These days, universities are establishing new image; UI(University Identity) for them because of rapid change of education environment in 21st century, The objective of UI is expressing university's image externally and unifying members internally. In the process of establishing university's image, Symbol mark plays a key role in differentiating other universities because of its visual effect as well as enhancing self-confidence. In this study, I suggest that symbol mark is an important brand asset in point of differentiation and identification and analyze 36 domestic universities' symbol mark designs. In the way of this analysis, I classified these symbol marks in the aspect of shapes and colors and studied current design along with character of each symbol marks by examining usage of emblem. Therefore this paper will be used as a basic reference to understand domestic universities' symbol mark trend and to establishing differentiating strategy in the future.

The purposes of this study were to classify the changing periods of apartment outdoor space in Korea and to clearly understand the specific characteristics of each period. The study has been done through on-site observation of apartment complexes, and through the analysis of housing estate planning techniques, rules and regulations affecting outdoor spaces during the rapidly developing era. The results of this study shows that three major periods with distinct characteristics were found, which were as follows: 1) The first well defined period spans from 1960 to 1990. In this period, apartment construction was rapid, and as a result, quality of housing environments were sacrificed. As little attention was given to the landscapes in apartment complex, they were constructed very simple and identical in outdoor space of apartment complex. This period can be referred to as the 'commonly universal period in apartment outdoor space'. 2) The second period spans from 1991 to 1996, during which time a housing construction project for two million residences was completed in order to significantly stimulate the provision of houses to the general public. As a result, regulations were relaxed causing housing environments to deteriorate. Although apartments were constructed very close together, there was some diversification and experimentation in outdoor styles. This period can be referred to as the 'congestion period of apartment outdoor space'. 3) The third period spans from 1997 to the present. During this time the number of unsold apartments has grown considerably throughout the country. Many different apartment complex marketing strategies have been employed to reduced the glut of unsold apartments. This experimental trend has continued and been well-received since the IMF period. The distinguishing characteristics of this period are the introduction of a rich natural landscape, the increase in communications among residents, the human oriented design, and the refined and elegant design for the outdoor street furnitures. As a result, this period can be named the "differentiation period of apartment outdoor space".

Petrological studies were performed on the Sanbangsan lava dome, located in the southwest of Jeju Island Volcanic Field. According to the lava ejection method, it is 'an internal primitive form' that is gradually pushed up and expanded by continuous magma injection from the bottom to the top of the vent and it corresponds to the 'low lava dome'. The rocks are partly plotted in the field of benmoreite, but mostly plotted in the field of trachyte of the Cox et al.(1979) classification diagram, and also mainly plotted in the field of trachyte of Le Maitre et al.(2002) and Zr/TiO₂-Nb/Y classification diagram. Therefore, the expression that described the rock of Sanbangsan lava dome as 'trachy-andesite' should be corrected to 'trachyte'. The volcanic rocks that consists in the Sanbangsan lava dome are trachyte containing normative quartz and shows differentiation trend in the range of 59.75-63.46 wt.% SiO₂.

This research investigates a dynamic mechanism underlying the co-evolution between network and space by applying hype-curve model, typical phenomenon which shows how new technologies and ideas initially adapted in the society. This study analysis the knowledge intensive industry of digital contents using social network analysis (SNA) in terms of structural, spatial, and temporal aspects, year of 2000, 2005, and 2010 focused on Seoul area. First of all, network and space establish 'inter-feedback' as a result of evolution and differentiation process. Second, it happen temporal 'delay' through the learning process stage of 'peak of inflated expectation' and 'trough of disillusionment.' As a result, Seoul develops with the technology commercialized-orient strategy affect government policy. This trend changes to technology-oriented development in Seoul area in the late of 2000 established 'self-organization' with geographical proximity organizations through learning process.

It is getting difficult to manage water resources in South Korea because more than half of annual precipitation is concentrated in the summer season and its intensity is getting severe due to global warming and climate change. Artificial recharge schemes can be a useful method to manage water resources in Korea adapting to climate change. Patent analysis enables us to prevent overlapping investment and to find out unoccupied technology. In this study, international patent trends and barriers of artificial recharge technology are analysed for patents of Korea, Japan, the United States and Europe. The four artificial recharge methods such as well recharge, surface infiltration, bank filtration and underground structures are classified as main class and the nine sub-technologies such as water intake, water treatment, injection wells, monitoring of groundwater flow, groundwater pumping, surface infiltration/soil aquifer treatment, radial collection well, iron/manganese treatment, and underground subsurface dam are classified as intermediate class. Water intake techniques are subdivided into five classifications. Total 1,281 of patents, searched by WIPS DB tool and selected after removing noisy patents, are analyzed quantitatively to evaluate application trends by year, applicant, country for each classified technologies and analyzed qualitatively to find out occupied and unoccupied technologies. It is expected that upcoming research and development project could be performed efficiently in that an avoidance plan for the similar patents and differentiation plan for the advancing patents are set up based on the quantitative and qualitative analysis results from this research.

The genetic variation in 10 indigenous Caucasian sheep breeds was studied with 14 micro-satellite loci in order to determine the genetic diversity among and between the breeds. Five breeds from Asia, five breeds from Europe and one breed from Africa, were included in order to study any relationships or influences they may have with the Caucasian sheep analyzed. A Karakul population from Uzbekistan was included in the study to see whether there was any Central Asian influence. All the 14 loci were found to be polymorphic in all the breeds, with the exception of ILST0056, which was monomorphic in Imeretian. A total of 231 alleles were generated from all the 688 individuals of the sheep analyzed. The mean number of alleles (MNA) at each locus was 16.5. The total number of alleles detected in all samples ranged from 13 in several loci to 23 in OarJMP029. Out of total 308 Hardy-Weinberg Equilibrium (HWE) tests, 85 gave significant results. After Bonferroni correction for multiple tests, 30 comparisons still remained significant to the experimental levels. The Gala population was the most diverse and Imeretian the least diverse with a MNA of 8.50 and 5.51, respectively. Gene diversity estimates exhibited the same trend and ranged from 0.803 in Gala and 0.623 in Imeretian, but generally there is higher diversity among the Caucasian breeds in comparison to other eference breeds. The closest breeds were Tushin and Bozakh with Da of 0.113 and most distant breeds were $Djallonk{\acute{e}}$ and North Rondalsy with Da of 0.445. Principal Component (PC) analyses were done. PC1 described 14% of the differences. PC2, which described 13% of the differences, further separated the Caucasian breeds from Asian breeds except Karakul and Awasi, and the two British breeds. PC3 described 10% of the differences, allowing better differentiation of the Caucasian breeds. A moderate degree of reliability was observed for individual-breed assignment from the 14 loci using different approaches among which the Bayesian method proved to be the most efficient. About 72% of individuals analyzed were correctly assigned to their respective breeds.

The Purpose of this study is to help the neck-tie business enterprise establish the reasonable marketing strategy meeting consumer' needs by grasping their characteristic of purchasing neck-ties and their attitudes toward trademarks. The findings of this study are as follows : 1. It was shown that the neck-tie enterprise tended to appeal to megazines, catalogues , etc as promotional politics, while the tips obtained by consumers would come from the showcase at the purchasing place. and the consumer showed a positive response to the salesperson's advice. For this result, it is required to place further emphasis on the marketing policy such as the display of products at the store or the education of sales persons. 2. It was shown that the consumer tended to use the department store as the purchasing place remarkably, and so it could be found that the use of the department store is becoming generalized to the consumer. But is was shown that the consumer sensitive to prices tended to make use of the marketplace as the purchasing place, so the practical marketing strategy should be established in relation to this trend. 3. The important elements excreting an influence on the consumer's purchasing the neck-tie were shown to be in orders of design > color> harmony > with suit > price > quality, and the product differentiation policy used by the business enterprise to appeal to the consumer was shown to be in orders of design >color > quality > material > price. Accordingly , it was consistent with the consumer's criterion for choice to an extent. 4. It was shown that the selling price for the neck-tie brand actually was higher for imported or technically cooperated brands than for the home-made brand. Thus, the consumer's perception of the price for the neck-tie was consistent with in this regard, consumers did not feel some difference in quality between the home -made neck-tie brand and the imported or technically cooperated neck-tie brand . Therefore, it is important to produce the product capable of satisfying the consumer's need by manufacturing the own brand on basis of impored technology.

Igneous rocks occurring in the northwesern part of Keumsan area, Chungcheongnam-do were studied petrogeochemically. The geology of this area is composed mainly of the Precambrian biotite gneiss, age-unknown Ogchon supergroup, Jurassic biotite granite, and Cretaceous volcanic rocks, pink feldspar granite and quartz porphyry. The biotite granite is gradually changes to leucocratic nature by going from center to periphery of the rock mass. It shows variation, with distance from the center, in chemical components: $SiO_2,\;Na_2O\;and\;K_2O$ increase, whereas $Fe_2O_3,\;CaO,\;P_2O_5,\;MgO,\;and\;TiO_2$ decrease. Based on geochemical data, the biotite granite and quartz porphyry belong to subalkaline series and I-type. They show calc-alkaline differentiation trend. The biotite granite shows little negative Eu-anomaly pattern, whereas quartz porphyry show marked negative Eu-anomaly pattern, indicating that quartz porphyry was evolved further, when compared with biotite granite.

Metallic biomaterials have been mainly used for the fabrication of medical devices for the replacement of hard tissue such as artificial hip joints, bone plates, and dental implants. Because they are very reliable on the viewpoint of mechanical performance. This trend is expected to continue. Especially, Ti and Ti alloys are bioinert. So, they do not chemically bond to the bone, whereas they physically bond with bone tissue. For their poor surface biocompatibility, the surface of Ti alloys has to be modified to improve the surface osteoinductivity. Recently, ceramic-like coatings on titanium, produced by plasma electrolytic oxidation (PEO), have been developed with calciumand phosphorus-enriched surfaces. A lso included the influences of coatings, which can accelerate healing and cell integration, as well as improve tribological properties. However, the adhesions of these coatings to the Ti surface need to be improved for clinical use. Particularly Silicon (Si) has been found to be essential for normal bone, cartilage growth and development. This hydroxyapatite, modified with the inclusion of small concentrations of silicon has been demonstrating to improve the osteoblast proliferation and the bone extracellular matrix production. Strontium-containing hydroxyapatite (Sr-HA) was designed as a filling material to improve the biocompatibility of bone cement. In vitro, the presence of strontium in the coating enhances osteoblast activity and differentiation, whereas it inhibits osteoclast production and proliferation. The objective of this work was to study Morphology of bone-like apatite formation on Sr and Si-doped hydroxyapatite surface of Ti-6Al-4V alloy after plasma electrolytic oxidation. Anodized alloys was prepared at 270V~300V voltages with various concentrations of Si and Sr ions. Bone-like apatite formation was carried out in SBF solution. The morphology of PEO, phase and composition of oxide surface of Ti-6Al-4V alloys were examined by FE-SEM, EDS, and XRD.

This study was performed to retrospectively pursue any correlation between renal cortex thickness (RCT), outer medulla thickness (OMT) on ultrasonography (US) and chronic kidney disease (CKD) with International Renal Interest Society (IRIS) stage. Medical records and US findings of the dogs diagnosed CKD were reviewed for comparing to those of the clinically healthy dogs from March. 2015 through June. 2016. To evaluate the correlation about normal and CKD patients, RCT and the OMT were measured on US images. RCT and OMT were adjusted by dividing body surface area for standardization (RCTS, OMTS). Also the ratio of RCT/OMT were calculated and these indices were evaluated to investigate any tendency between 5 groups (normal and 4 IRIS stages) using Jonckheere-Terpstra trend test (J-T test). The RCTS showed a declining tendency (p < 0.02) and the OMTS showed an inclining tendency from normal through each IRIS stage (p < 0.01). The RCT/OMT showed also declining tendency (p < 0.01). Although the gold standard for renal function including GFR is lack, it is thought that differentiation between normal and CKD patients could be possible on US measurement of renal cortex and outer medulla thickness, which could be an alternative index for kidney function in diagnostic imaging.
