To build the consistency among different metadata systems and to increase the interoperability of that systems even among different domains, naming rules and glossaries for the data elements are necessary. This study provides discussion of naming and identification of the data element concept, data element, conceptual domain, value domain, and its meta model. This study also describes example naming conventions based on ontology derived from the combination with object, properties, and representation of data elements. The naming principles and rules described in this study use I-R analysis, DC metadata set, and SHOE 1.0 as an example of the scientific documents. This study would be a guideline to build the naming rules of metadata based on ontology in various domains.

Apolipoprotein E (apoE) restriction isotyping used oligonucleotides to amplify apoE gene sequences containing amino acid positions 112 and 158. The amplification products were digested with HhaI and subjected to electrophoresis on $4\%$ agarose gel. Each of the isoforms was distinguished by a unique combination of HhaI fragment sizes that enabled unambiguous typing of all homozygotic and heterozygotic combinations. HhaI cleaves at GCGC encoding 112arg (E4) and 158arg (E3, E4), but does not cut at GTGC encoding 112cys (E2, E3) and] 58cys (E2). DNA was isolated from 72 study participants and apoE genotypes were determined utilizing the polymerase chain reaction and restriction isotyping. In the entire group of subjects, $38 (52.8\%)$ had apo E4/4 or E3/4 (Group E4), $28(38.9\%)$ had the apo E3/3 genotype (Group E3) and $6(8.3\%)$ had apo E2/2 or E2/3 (Group E2). This genotypic information may help to identify individuals at increased risk for several diseases.

After scientific verification of the osteointegration of dental implants, the overall efficiency of dental implants has been generally accepted. Thus, implants now play a major role in the clinical treatment of an edentulous mandible, and in the prosthetic maintenance equipment for partial edentulous mandible patients. Yet, for the successful long-term maintenance of implants, careful consideration of the bio-mechanics is needed to ensure that the maximum stress in the mandible as a result of chewing is maintained under a critical value. Accordingly, this study focuses on reducing the maximum stresses in an implanted mandible, especially in the cortical bone. Thus, the stresses in the implant and mandible are analyzed using finite element packages, including I-DEAS and NISA II/DISPLAY III, using a local zooming technique for a concentrated stress analysis. In addition, the von-Mises stress and principal stress in the mandible are both checked to determine the best combination.

This treatise, after review recent data on Oriental Medical toxicity, gets a conclusion on toxic concept of Oriental Medicine. 1. In the oriental medicine, the concept of toxic character contains propensity which disposition is inclined, and general meaning covered with the effect of a medicine, a side effect, formation of a medicine Besides, the concept diversely is used in the cause of a disease, names, symptoms, how to treat, medicines, prevention name, etc. 2. Every herbal drugs has toxic character. Levels of toxicity are nonexistence(無毒), existence(有毒), a little(小毒), always(常毒), serious(大毒), fatal toxic(劇毒), whose concepts in the Oriental Medicine are divided relative and absolute at the same time. 3. The examples of the fatal events by poisoning up to now are more than 400 cases(in China). 4. The factors of toxicity are the amount used unsuitably, the combination, directions, and interactions between western and oriental medicine, etc. The reduction of toxicity and how to detoxicate is several methods. The toxic science in Oriental Medicine based on the formation of oriental medicine present principles which use herbal drugs safely and availablely, utilizing th dispositions and efficiencies. It has positive, learning spirits which prevent abuse of oriental medicine, and which exactly diagnose and use the herbal drugs in the treatment with absolute toxic medicine. However, I think that scientific, positive experimental research is necessary to setup dose-response relation, be in relative quantity of toxic character, operate on the reactive mechanism exactly.

In South Korea, there are about 80 Global Positioning System (GPS) monitoring stations providing total electron content (TEC) every 10 min, which can be accessed through Korea Astronomy and Space Science Institute (KASI) for scientific use. We applied the computerized ionospheric tomography (CIT) algorithm to the TEC dataset from this GPS network for monitoring the regional ionosphere over South Korea. The algorithm utilizes multiplicative algebraic reconstruction technique (MART) with an initial condition of the latest International Reference Ionosphere-2016 model (IRI-2016). In order to reduce the number of unknown variables, the vertical profiles of electron density are expressed with a linear combination of empirical orthonormal functions (EOFs) that were derived from the IRI empirical profiles. Although the number of receiver sites is much smaller than that of Japan, the CIT algorithm yielded reasonable structure of the ionosphere over South Korea. We verified the CIT results with NmF2 from ionosondes in Icheon and Jeju and also with GPS TEC at the center of South Korea. In addition, the total time required for CIT calculation was only about 5 min, enabling the exploration of the vertical ionospheric structure in near real time.

This paper starts with the assumption that in order for the popularization of hanbok leading to greater interest among the public for Hanbok and its uses in everyday life, the period for Hanbok events each year must be solidified, making it a standardized provide opportunities for participation regardless of demographic. Globalization of Hanbok most occur through a combination of related academic fields, division of roles in fields of expertise, and a scientific understanding of Hanbok. Thus various Hanbok-related programs such as contests, fashion shows, experience centers and exhibitions should be provided in one unified setting. Government sponsored Hanbok cultural events have generally been aimed at foreigners or foreign human residency, while events in Korea hae generally been carried out by a more diverse rage of groups, making it difficult for the general population to obtain information or participate actively. In order for hanbok to maintain its tradition as the national costume of Korea, Long-term develop plans must be set. Along with popularization in order to bring hanbok into everyday life, methods for the globalization of hanbok must be explored, providing opportunities to spotlight the diversity and characteristics of Korean costumes, in various events which promote participation, festival-forming and globalization of hanbok culture considering elements such as time (yearly, monthly etc.) and audience (age group, social level etc.).

In the millenium, which will be characterized by its global culture, a strong sense of identity of one's culture is needed to nature one's culture in a way that more people can participate in creating, enjoying and consuming it. In order to respond to both globalization and localization, natural and cultural backgrounds of such should be considered in the conversation of nature, so that the optical and color environment can have local identity while undergoing sustainable development. Therefore, the objective of this research is to enhance the image of a city, which is endowed with beautiful scenery and unique culture, but has lost its identity since industrialization An through a scientific and systematic color planning The Research was conducted as follows. First, color environment which doesn't reflect local characteristics due to modernism which emphasizes on uniformity was examined. Second, standard and analysis of environment color planning were examined. Natural color specimen was use to make a palette of nature colors, from which colors for architecture were extracted to come up with color combination types. Without traditional architecture philosophy, materials and colors, which were once in harmony with the environment, it is impossible to clean up the environment all together. However by using colors to control new city plans, urban redevelpment, construction and renovation gradually, that process can be effective and less costly.

Because of lack of accurate understanding of the mechanism of urban heat island (UHI) phenomenon and lack of scientific discussion, it is hard to come up with effective measures to mitigate UHI phenomenon. This study systematically described the UHI and suggested the solutions using green-infrastructure (green-infra). The factors that control UHI are very diverse: radiant heat flux, latent heat flux, storage heat flux, and artificial heat flux, and the air temperature is formed by the combination effect of radiation, conduction and convection. Green-infra strategies can improve thermal environment by reducing radiant heat flux (the albedo effect, the shade effect), increasing latent heat flux (the evapotranspiration effect), and creating a wind path (cooling air flow). As a result of measurement, green-infra could reduce radiant heat flux as $270W/m^2$ due to shadow effect and produce $170W/m^2$ latent heat flux due to evaporation. Finally, green-infra can be applied differently on the macro(urban) scale and micro scale, therefore, we should plan and design green-infra after the target objects of structures are set.
