김영근,김수경,안기홍 한밭대학교 정보통신전문대학원 2005 정보통신전문대학원 논문집 Vol.3 No.1

정보통신의 발전은 경제 구조에 많은 변화를 가져왔으며, 향후에도 많은 변화를 예고하고 있다. 가장 대표적인 것은 경제 흐름의 근간이라 할 수 있는 유통의 변화이다. 이것은 통신망 위에 구축되는 가상의 공간에서 이루어지는 유통을 지칭하는 것으로, 빠른 속도로 발전하고 있다. 이러한 빠른 발전에도 상품데이터베이스를 구성하는 것에는 매우 불합리한 비효율성이 존재한다. 상품데이터베이스 구성의 가장 큰 비효율은 싸이트들이 개별의 데이터베이스를 구성한다는 것이다. 이런 문제를 해결하기 위해 시멘틱웹의 RDF(Resource Description Framework)언어를 이용하여 웹 온톨로지를 구성하여 공급자와 판매자간 상품 데이터를 공유하게 된다면, 전자상거래에서 상품데이터베이스 구성의 비효율성을 제거 할 수 있다. 따라서 본 논문에서는 RDF의 소개와 RDF 웹 온톨로지 편집기를 제작하고, 구성된 RDF를 참조하여 간단한 쇼핑몰을 구성하여 온톨로지를 통한 데이터의 효율적 상호운영성(Interoperability)을 증명하여, 현재 제안되고 있는 상품 카탈로그 분야의 발전에 기여하고자 한다. IT development has brought about many changes in an economic structure, and will bring about many changes in the future. The most representative thing is the change of distribution which is a basis of the economic flow. It means a distribution an a virtual space built through communication network. It has rapidly developed. However, building the product database by each site for numberless products is very unreasonable simple repeating process. To solve this problem, if the product data is shared between a supplier and seller through the web ontology by using the Semantic Web RDF (Resource Description Framework) language, an efficiency of e-commerce will be created. Accordingly, the study is intended to prove an efficient interoperability of data through ontology by introducing the RDF, fabricating the RDF web ontology editor, and building a simple shopping mall through organized RDF, and to contribute to a development of currently-proposed product catalog field.

Properties analyses and treatment characteristics of waste slurry discharged in the wetted flue gas desulfurization process using Mg(OH)₂as a absorbent were investigated. Aeration and coagulation test were carried out to evaluate variation of some factors such as COD, SS, T-N, etc. related to waste slurry treatment. The hydraulic retention time(HRT) and coagulant dosage rate were applied as operating variables in experiment. As experimental results, the reduction effects of COD, SS in aeration test were distinct, due to oxidation of SO₃ and floc, formation of suspended solids. It was also found that the reduction efficiencies of SS and T-P in coagulation test are higher than 90%.

The dosimetric system consisting of parallel plate type of air-filled ionization chamber and charge-to-voltage converter was designed to do daily constancy check of the high energy photon beam of Clinac 1800C linear accelerator(Varian Co., Pola Alto, California, USA). The ionization chamber was fabricated using acrylic plate for the chamber medium and printed circuit board for electrical configuration. The sensitive volume of the chamber was 1.6cc. High voltage generator was fabricated using the conventional 9V batteries to apply the high voltage(300V) to the electrode of the ionization chamber. Also the charge-to-voltage converter was designed to collect the electrons produced in the ionization chamber cavity. The output reading was converted into the digital signal using the commercially available digital multimeter to produce four-digit readings. The major parameters of the chamber characteristics such as reproducibility. linearity. leakage current. zero drift. timer error. dose-rate effect and polarity effect etc. were measured. These data were comparable to those of the QA-purpose dosimetric system commercially available in the market. Also this dosimetric system can be extended to do the flatness/symmetry check of the photon as well as the constancy check of the various electron beams for the purpose of outputs as well as energy measurements.

The aim of this study is to suggest a design proposal for the restoration of Suwon Youngdong Market which is located near Paldalmoon. It is expected that the potential of the Market would be enhanced greatly due to the increase of tourists followed by the progress of Hwaseong Restoration Program. To make the Market as a major node of tourist network, a design proposal arranging shops and circulations based on two hyper-plazas is suggested. The two plazas which has to be sunken due to the height limitation and the amount of space to be accommodated is designed to pulls pedestrians into the market and induce them to go around the market following floating pathways. The two hyper-plazas characterized by their dynamic spaces plays a key role as a landmark in the tourist pathway and also as a community center of Youngdong Market and the vicinity area.

Objectives: Measuring the quality of care is paramount to inform policies for healthcare services. Nevertheless, little is known about the quality of primary care and acute care provided in Korea. This study investigated trends in the quality of primary care and acute care. Methods: Case-fatality rates and avoidable hospitalization rates were used as performance indicators to assess the quality of primary care and acute care. Admission data for the period 2008 to 2020 were extracted from the National Health Insurance Claims Database. Case-fatality rates and avoidable hospitalization rates were standardized by age and sex to adjust for patients' characteristics over time, and significant changes in the rates were identified by joinpoint regression. Results: The average annual percent change in age-/sex-standardized case-fatality rates for acute myocardial infarction was -2.3% (95% confidence interval, -4.6 to 0.0). For hemorrhagic and ischemic stroke, the age-/sex-standardized case-fatality rates were 21.8% and 5.9%, respectively in 2020; these rates decreased since 2008 (27.1 and 8.7%, respectively). The average annual percent change in age-/sex-standardized avoidable hospitalization rates ranged from -9.4% to -3.0%, with statistically significant changes between 2008 and 2020. In 2020, the avoidable hospitalization rates decreased considerably compared with the 2019 rate because of the coronavirus disease 2019 pandemic. Conclusions: The avoidable hospitalization rates and case-fatality rates decreased overall during the past decade, but they were relatively high compared with other countries. Strengthening primary care is an essential requirement to improve patient health outcomes in the rapidly aging Korean population.

Geun-Yeong Koa,Ju-Sung Jun 한국무역연구원 2017 The International Academy of Global Business and T Vol.13 No.1

The purpose of this study was to practically investigate how leisure activities and leisure space are composed according to the leisure learning attitudes of front-line workers at a foreigner-only casino. For this study, 353 employees of a casino located in Seoul were selected. The collected study data were analyzed using social network analysis, and the results of the study were as follows. First, the connection centrality values of the present and the desired leisure activities based on the employees’ leisure learning attitudes showed that the distribution was more diverse for the current than the desired activities, but the concentration was stronger for the desired leisure activities. Second, the connection centrality values of the current and desired leisure spaces based on the leisure learning attitudes showed that the distribution was more diverse with the desired than with the current spaces, but the concentration was stronger with the current spaces. This shows that there were differences in the casino employees’ present and desired leisure activities and spaces based on their leisure learning attitudes, as well as showing a circular relationship between the leisure learning attitudes, leisure activities, and leisure spaces; the differences between the employees’ present and desired leisure activities and spaces could be visualized through network analysis from the perspective of their attitudes.

Caffeic acid O-metyltransferase (COMT) is involved in the melatonin synthesis in rice (Oriza sativa) plants

Geun-hee Choi,Yeong Byeon,Hyoung Yool Lee,Kyoungwhan Back 한국육종학회 2015 한국육종학회 심포지엄 Vol.2015 No.07

Caffeic acid O-methyltransferase (COMT) methylates N-acetylserotonin into melatonin; that is, it has N-acetylserotonin O-methyltransferase (ASMT) activity. The ASMT activity of COMT was first detected in Arabidopsis thaliana COMT (AtCOMT). To confirm the ASMT activity of COMT in other plant species, we evaluated the ASMT activity of a COMT from rice (Oryza sativa) (OsCOMT). Purified recombinant OsCOMT protein from Escherichia coli was used to validate the high ASMT activity of OsCOMT, similar to that of AtCOMT. The Km and Vmax values for the ASMT activity of OsCOMT were 243 μm and 2,400 pmol/min/mg protein, which were similar to those of AtCOMT. Similar to AtCOMT, OsCOMT was localized in the cytoplasm. In vitro ASMT activity was significantly inhibited by either caffeic acid or quercetin in a dose-dependent manner. Analogously, in vivo production of melatonin was significantly inhibited by quercetin in 4-week-old detached rice leaves, suggestive of a positive role of COMT in melatonin biosynthesis in plants.
