An Analysis on Consumer Market of e-book in Japan

The e-book market in Japan is growing in this decade and according to Impress R&D this tendency will be continue. In this paper, we collected 3,000 samples by online survey and found a tendency of consumption of e-book in Japan by using conjoint analysis. We found 1) attachment to physical objects in Japanese consumers, 2) high MWTP for device and providers. We check this by other questions and found tendency of Japanese consumer for e-distribution services

A study on business structure of E-book in non-English Language: Case study of Japan

The competitive model of e-book is a little bit different from other contents business like movie, television, music, etc. Partially it depends on cultural policy of each countries but it is affected by bargaining power among publishers and distributors. In English Language market we can refer authoritative report like OECD (2012) or working papers like Johnson. They are focusing on trading contract or structure of e-book market in U.S.A., U.K., Australia, Canada, etc.. In Japan and maybe some developed European continental countries the assortment of e-book is limited and distributor cannot expand its sales like as England although according to JAGAT (2010) Japanese e-book market ($574 million)was third times as that of the U.S.($169 Million) in 2009

A successful model of regional healthcare information exchange in Japan: Case Study in Kagawa Prefecture

In this study, we focused on analysis of healthcare data exchange over the network. For the advance of broadband capability development, many governments expect online medical information exchange between medical institutions. Japanese government also has tried to deploy ICT in the healthcare field. In Japan, many healthcare ICT projects started, but almost of all the projects face many issues and failed to continue. This situation caused us to clarify the success factor of healthcare information exchange network. For inspecting the success factors, we analyzed information access of healthcare systems in Kagawa prefecture of Japan. Kagawa prefecture is one of the most advance areas for healthcare information technology. We analyzed four medical ICT projects in Kagawa prefecture: K-MIX, Critical Pathway for Diabetes, E-prescription, and PHR. In addition, we inspected characteristics of exchanged data in the network, and stakeholder involved in these projects. This analysis lets us find various types of healthcare ICT projects. Characteristic of data processed in the projects caused differences of characteristic of the projects. On the other hand, multiple systems process same data, though the project does not share the data itself. Considering various types of medical information exchanges projects, we propose classification and standard format of exchanged data according to their characteristic are critical for efficient business deployment. --e-Health,regional healthcare information exchange,EHR

Identification Codes to Identify Multiple Objects

In the case of ordinary identification coding, a code is devised to identify a single object among $N$ objects. But, in this paper, we consider an identification coding problem to identify $K$ objects at once among $N$ objects in the both cases that $K$ objects are ranked or not ranked. By combining Kurosawa-Yoshida scheme with Moulin-Koetter scheme, an efficient identification coding scheme is proposed, which can attain high coding rate and error exponents compared with the case that an ordinary identification code is used $K$ times. Furthermore, the achievable triplet of rate and error exponents of type I and type II decoding error probabilities are derived for the proposed coding scheme.Comment: 14 pages, submitted to IEEE Transactions on Information Theor

Improvement of biodistribution profile of a radiogallium-labeled, αvβ6 integrin-targeting peptide probe by incorporation of negatively charged amino acids

Objective Pancreatic ductal adenocarcinoma (PDAC) is one of the most lethal cancers. Since αvβ6 integrin has been reported as a promising target for PDAC diagnosis, we previously developed H-Cys(mal-NOTA-67Ga)-(Gly)6-A20FMDV2-NH2 ([67Ga]CG6) as an αvβ6 integrin-targeting probe. Although [67Ga]CG6 specifically binds to αvβ6 integrin-positive xenografts, the uptake of [67Ga]CG6 in the organs surrounding the pancreas, such as the liver and spleen, was comparable to that in the αvβ6 integrin-positive xenografts. We hypothesized that the undesirable accumulation of [67Ga]CG6 in those organs was caused by the positive charges of [67Ga]CG6 (+ 3). In this study, we aimed to decrease [67Ga]CG6 uptake in the liver and spleen by reducing the electric charges of the probe. Methods We synthesized H-Cys(mal-NOTA-67Ga)-(Asp)6-A20FMDV2-NH2 ([67Ga]CD6) and evaluated its affinity to αvβ6 integrin via in vitro competitive binding assay. Isoelectric points of the probes were determined by electrophoresis. Biodistribution study, autoradiography, and immunostaining for β6 integrin were conducted using αvβ6 integrin-positive and negative tumor-bearing mice. Results In vitro competitive binding assay showed that the alteration of the linker had a negligible impact on the affinity of [67Ga]CG6 to αvβ6 integrin. The results of electrophoresis revealed that [67Ga]CG6 was positively charged whereas [67Ga]CD6 was negatively charged. In the biodistribution study, the uptake of [67Ga]CD6 in the αvβ6 integrin-positive xenografts was significantly higher than that in the αvβ6 integrin-negative ones at 60 and 120 min. The uptake of [67Ga]CD6 in the liver and spleen was more than two-fold lower than that of [67Ga]CG6 at both time points. In the immunohistochemistry study, the radioactivity accumulated areas in the autoradiogram of the αvβ6 integrin-positive xenograft roughly coincided with β6 integrin-expressing areas. Conclusion We have successfully reduced the nonspecific uptake in the liver and spleen by altering the linker amino acid from G6 to D6. [67Ga]CD6 overcame the drawbacks of [67Ga]CG6 in its biodistribution

A comparison analysis of smart phone competition model: Korean case and Japanese case

This paper investigated the driving force of diffusion in smart phone market by analysing usage of them and making their component model. Main findings are following four: 1) In Korea and Japan their average smart phones' traffic per user has been the world's highest level. But its diffusion pattern is very different. 2) The Korean government and private companies strongly support diffusion of smart phones but not so much in Japan. 3) Korean and Japanese Mobile phone companies and/or manufacturers try to build their application stores. They collect funds for developing tools and application developers. 4) Importance of customises or localise for drastic diffusion
