  • The Internet of Things (or IoT for short) which refers to uniquely identifiable objects and their virtual representations in an Internet-like structure is to be reality today. The amount of data on IoT is expected to increase abruptly and there are several key issues like usefulness interoperability between multiple distributes systems, services and databases. In this paper a methodology is proposed to realize a recently developed cloud service model, Contents as a Service (CaaS), which is contents delivery model referred to as 'on-demand contents'. In the proposed method, the global object identification, ePosition, comprising the structured form of two sorts of text strings with a separation symbol like # is applied to identify a specific content and registered with the content at the same server. It is easy-to-realize and effective to solve the interoperability problem systematically and logically. Some APIs for the proposed CaaS service are to be converged to provide some upgraded cloud service model such as 'CaaS supported SaaS' and 'CaaS supported PaaS'.

  • A local isolate of chicken anemia agent (CAA), isolate 89-69. was tested for pathogenicity for chickens. When chickens from a specific pathogen free (SPF) flock were inoculated intramuscularly with the isolate at one day old, all the chickens showed severe anemia at 14 to 18 days post inoculation(DPI) and returned to normal at 25DPI, Some of the inoculated chickens (27∼33%) died between 13 to 17 DPI's with lesions of severe aplasia of bone marrow and thymic atrophy. In chickens kept in contact with inoculated chickens, some of the chickens had anemia at 25 and 28 DPI's. Virus could be reisolated from inoculated as well as in contact chickens till 21 DPI. Antibodies to CAA could be detected in all inoculated and in contact chickens when tested at 42 DPI by the indirect fluorescent antibody method. When chickens from a different SPF flock were inoculated at one day old, degrees of anemia, both in frequency of incidence and severity, were low These chickens were proved partly to have antibodies to CAA when tested for hatchmates. In a survey for antibodies to CAA in field chicken flocks, one out of 7 flocks(14%) aged 3 to 10weeks was antibody positive whereas 19 out of 20 flocks(95%) over 20 weeks of age were positive. Altogether 29 out of 39 flocks (74%) were antibody positive.

  • In this paper, we implement a crossword game, which operate by speech. The CAA (Cross Array Algorithm) produces the crossword array randomly and automatically using an domain-dictionary. For producing the crossword array, we construct seven domain-dictionaries. The crossword game is operated by a mouse and a keyboard and is also operated by speech. For the user interface by speech, we use a speech recognizer and a speech synthesizer and this provide more comfortable interface to the user. The efficiency evaluation of CAA is performed by estimating the processing times of producing the crossword array and the generation ratio of the crossword array. As the results of the CAA's efficiency evaluation, the processing times is about 10ms and the generation ratio of the crossword array is about 50%. Also, the recognition rates were 95.5%, 97.6% and 96.2% for the window sizes of "$7{\times}7$", "$9{\times}9$," and "$11{\times}11$" respectively.}11$" respectively.vely.

  • 다양한 스마트 디바이스의 보급으로 높은 이동성을 기반으로한 무선 인터넷 환경에서의 클라우드 동기화 서비스 이용이 보편화되고 있다. 그러나 클라우드 서비스의 동기화 기법은 갱신된 정보를 보유한 디바이스가 서비스로 갱신정보 및 데이터를 전달하고, 서비스를 중심으로 등록된 각 디바이스로 다시 한번 전달하는 2 단계이루어지기 때문에 효율적인 동기화 성능을 제공하기 어렵다. 그러므로 본 논문에서는 등록된 모든 디바이스 간의 동기화를 제공하기 위한 재사용성 이 높은 CaaS(Component as a Service)를 기반으로 멀티 디바이스 동기화(Multi Device Synchronization Service, MSS) 설계하고, 사용자 디바이스의 컨텍스트에 따른 효율적인 동기화 기법을 위한 택틱(Tactic)을 제안한다.

  • A full-length cDNA encoding ribulose-1,5-bisphosphate carboxylase small subunit (rbcS) has been isolated and its nucleotide sequence determined from root in ginseng plant (Panax ginseng). The rbcS cDNA of ginseng is 790 nucleotides long and has an open reading frame of 549 bp with deduced amino acid of 183 residues (pI 8.37), 20.5 kDa. The deduced amino acid sequence of rbcS matched to the previously reported rbcS protein genes and showed a high similarity with the $78\%$ identity with rbcS of Helianthus annuus (CAA68490). In the phylogenetic analysis based on the amino acid residues, the ginseng rbcS was clustered with H. annuus (CAA68490), C. morifolium (AA025119) and L. sativa (Q40250).

  • Objective : The clinical and pathological characteristics of 10 cases of cerebral amyloid angiopathy (CAA)-related cerebral lobar hemorrhage (CLH) that was diagnosed at autopsy were investigated to facilitate the diagnosis of this condition. Methods : The clinical characteristics of 10 cases of CAA-related CLH were retrospectively reviewed, and a neuropathological examination was performed on autopsy samples. Results : The 10 cases included two with a single lobar hemorrhage and eight with multifocal lobar hemorrhages. In all of the cases, the hemorrhage bled into the subarachnoid space. Pathological examinations of the 10 cases revealed microaneurysms in two, double barrel-like changes in four, multifocal arteriolar clusters in five, obliterative onion skin-like intimal changes in four, fibrinoid necrosis of the vessels in seven, neurofibrillary tangles in eight, and senile plaques in five cases. Conclusion : CAA-related CLHs were located primarily in the parietal, temporal, and occipital lobes. These hemorrhages normally consisted of multiple repeated CLHs that frequently bled into the subarachnoid space. CAA-associated microvascular lesions may be the pathological factor underlying CLH.

  • CATIA V5 is one of the most preferred softwares in product design for domestic and industrial use. But with the development of the IT industry, design data by CATIA V5 can easily be hacked and stolen especially via the internet and through assistance storage medium. The design data could be protected through executive, physical and technical security system. The best way to maintain confidentiality of data from unauthorized access is to have a cryptosystem of the technical security. In this paper, a cryptosystem for the protection of design data was being proposed. The memory contains the file information made by the New and Open function of CATIA V5. No error can be expected even if the file changed before of after the application of Save and Open function, A cryptosystem was constructed in CATIA V5 by inserting crypto algorithm before and after the I/O process. The encryption/decryption algorithm of each function was based on the complex cipher, which applied permutation cipher and transpose cipher. The file security system was programmed in CAA V5 and Visual C++.
