Background: With ageing and growing importance of disease management system, it is necessary to investigate the extent of regional difference in service utilization for chronic diseases among the elderly and to reflect it in designing the system. Methods: A multiple regression analysis and descriptive statistics analyses were employed using patient survey, which covers nationwide health facilities and their users. Results: While the differences in the rate of service utilization/utilization outside living area between urban and rural areas or between income levels are not large, considerable variations are observed within urban or rural areas and within income groups. Conclusion: This results suggest that it is important to subsidize economically disadvantaged segments of the population and residents of less-favored areas to be better-equipped for chronic disease management in order to prevent the development of severe ailments and the need for treatment at higher-level medical institutions. Improvements to the service infrastructure in vulnerable regions are essential.

As the development of artificial intelligence (AI) technology spreads to various industrial sectors, diversity in AI utilization rapidly increases, creating rich user experience. In addition, AI is required to solve various social problems through the use of public data. The spread of AI utilization across all sectors will continue, covering such industrial and public demands. This article examines the domestic and international trends in AI utilization technologies and establishes the direction of research and development (R&D), which is highly consistent with Korea's AI policy. ETRI, which leads AI's national R&D, has used its experience to establish AI R&D implementation strategies as well as technology roadmaps for the utilization of AI to improve individual quality of life, continuous growth in society, industrial innovation, and the solutions to public societal problems. In addition, it has derived tasks and implementation strategies for developing AI utilization technologies in 10 major areas including medical services.

본 연구는 가열 한우육 및 호주산우육 스테이크에서 심부온도에 따른 glucose, lactate 및 핵산 분해 물질 함량을 비교하고자 실시하였다. 시료로 한우육(거세우, 1등급) 및 호주산우육(Bos indicus, 100일 곡류 비육)의 등심(M. longissimus dorsi)과 우둔(M. semimembranosus)를 약 2 cm 두께로 절단하여 각각 세 그룹으로 나누고, $180^{\circ}C$ 오븐에서 심부온도가 각각 50, 70 및 $90^{\circ}C$가 되도록 가열하였다. Glucose 함량은 심부온도에 관계없이 한우육 스테이크가 호주산우육 스테이크에 비해 현저하게 높았다(P<0.05). 이와 반대로 lactate 함량은 한우육 스테이크가 호주산우육 스테이크보다 낮았다(P<0.05). 핵산 분해 물질 중 Hx 함량은 모든 심부온도에서 한우육 스테이크가 호주산우육 스테이크보다 낮았던 반면(P<0.05), GMP, IMP 및 inosine 함량은 한우육 스테이크가 높았다(P<0.05). 심부온도가 증가함에 따라 쇠고기 스테이크의 glucose 함량은 감소하는 경향을 보였으나, lactate 함량은 일정한 경향을 보이지 않았다. 또한 핵산 분해 물질 함량은 심부온도의 증가에 따라 유의적인 변화를 보이지 않았다. 따라서 가열 한우육 스테이크의 단맛 및 감칠맛 관련 풍미 전구물질 함량이 호주산우육 스테이크보다 높았다.

In recent years, more data is being generated for the activation of the SNS, the spread of Smartphones and the development of IT technology. Therefore, it is to collect large amounts of data, analyze and ensure meaningful information has become important. The use of these data are formed on the global trend. Big data so-called, has attracted attention as a source of new business. Big Data can then give us the opportunity to be able to create a new customer and diversify the business. So, many companies have investment and effort for big data utilization. However, technology, infrastructure, human resources is different for each of the companies. Therefore, it is necessary to diagnose the level of big data utilization companies. In this study, through a literature review of existing, we derived the success factors for the big data utilization. And developed a diagnostic indicator that allows success factors derived, can be used to determine levels of big data utilization of the company. In addition, as a development of diagnostic indicators, were carried out case studies to diagnose company. Through this study, it will be an opportunity to be able to be reflected in the strategy of big data utilization company.

This paper diagnosed the assessment problems and development types of the simple statement of the Sea Area Utilization Consultation System. and suggested the key assessment items for system improvement. The major types of Public Water occupation and use, and distribution characteristic of regional and coastal were analyzed by evaluate 529 review items during 2010-2012. The artificial structure installation including harbor and fishing port facilities in the South and West coast, and seawater supply and drainage for land-based aquaculture and power plant were dominated. The checklists considering each types of occupation and use in Public Water were suggested. In addition, policy proposals for system improvement were suggested.

The ${\alpha}$-galactosidase-coding gene agaAJB13 was cloned from Sphingomonas sp. JB13 showing 16S rDNA (1,343 bp) identities of ${\leq}97.2%$ with other identified Sphingomonas strains. agaAJB13 (2,217 bp; 64.9% GC content) encodes a 738-residue polypeptide (AgaAJB13) with a calculated mass of 82.3 kDa. AgaAJB13 showed the highest identity of 61.4% with the putative glycosyl hydrolase family 36 ${\alpha}$-galactosidase from Granulicella mallensis MP5ACTX8 (EFI56085). AgaAJB13 also showed <37% identities with reported protease-resistant or Sphingomonas ${\alpha}$-galactosidases. A sequence analysis revealed different catalytic motifs between reported Sphingomonas ${\alpha}$-galactosidases (KXD and RXXXD) and AgaAJB13 (KWD and SDXXDXXXR). Recombinant AgaAJB13 (rAgaAJB13) was expressed in Escherichia coli BL21 (DE3). The purified rAgaAJB13 was characterized using p-nitrophenyl-${\alpha}$-D-galactopyranoside as the substrate and showed an apparent optimum at pH 5.0 and $60^{\circ}C$ and strong resistance to trypsin and proteinase K digestion. Compared with reported proteaseresistant ${\alpha}$-galactosidases showing thermolability at $50^{\circ}C$ or $60^{\circ}C$ and specific activities of <71 U/mg with or without protease treatments, rAgaAJB13 exhibited a better thermal stability (half-life of >60 min at $60^{\circ}C$) and higher specific activities (225.0-256.5 U/mg). These sequence and enzymatic properties suggest AgaAJB13 is the first identified and characterized Sphingomonas ${\alpha}$-galactosidase, and shows novel protease resistance with a potential value for basic research and industrial applications.

A channel-shared modified accelerative pre-allocation wavelength division multiple access (CMAP-WDMA) media access control (MAC) has been proposed for metro-WDMA networks, as an extension of modified pre-allocation wavelength division multiple access (MAP-WDMA) MAC protocol. Similarly, CAP WDMA as an extension of accelerative pre-allocation wavelength division multiple access (AP-WDMA) MAC protocol. Performance of CMAP- and CAP-WDMA was extensively investigated under several channel sharing methods (CSMs), asymmetric traffic load patterns (TLPs), and non-uniform traffic distribution patterns (TDPs). The result showed that the channel utilization of the CMAP-WDMA always outperforms that of CAP-WDMA at the expense of longer channel access delay for channel shared case while CMAP-WDMA provided higher channel utilization at specific network conditions but always shorter channel access delay than CAP-WDMA for non-channel shared case. Additionally both for CMAP- and CAP-WDMA, determining an effective CSM is a critical design issue because TDPs and TLPs can be neither managed nor expected while CSM is manageable, and the CSM supporting the best channel utilization can be recommended.
