Parsed the ECG descriptions in DICOM 3.0 standard and accomplished a DICOM-ECG file which conforms to the DICOM standard by a toolkit DCMTK. The DICOM-ECG file can communicate with systems which support DICOM standard directly.

Entity normalization, or entity linking in the general domain, is an information extraction task that aims to annotate/bind multiple words/expressions in raw text with semantic references, such as concepts of an ontology. An ontology consists minimally of a formally organized vocabulary or hierarchy of terms, which captures knowledge of a domain. Presently, machine-learning methods, often coupled with distributional representations, achieve good performance. However, these require large training datasets, which are not always available, especially for tasks in specialized domains. CONTES (CONcept-TErm System) is a supervised method that addresses entity normalization with ontology concepts using small training datasets. CONTES has some limitations, such as it does not scale well with very large ontologies, it tends to overgeneralize predictions, and it lacks valid representations for the out-of-vocabulary words. Here, we propose to assess different methods to reduce the dimensionality in the representation of the ontology. We also propose to calibrate parameters in order to make the predictions more accurate, and to address the problem of out-of-vocabulary words, with a specific method.

It is our great pleasure to announce that the Taehan Kan Hakhoe Chi (The Korean Journal of Hepatology) was approved for listing, from 2002, in the Index Medicus, Medline/PubMed of the National Library of Medicine, NIH of USA. Herein, I review the searching tools employing a Medical Subject Heading (MeSH) such as liver disease and liver neoplasm or an author index for this Journal in the PubMed at a website. Of course, The Korean Journal of Hepatology should be continually striving to be upgraded. Dream comes true.

To extract texture features from medical images, the approaches for multi-scale complexity and multi-scale fractal dimension were proposed in this paper. The extracted texture features were used in the medical image retrieval experiments. The complexity measurements used include permutation entropy and 2D-C0 complexity. The former is used to analyze one dimensional signal, and the latter is used to analyze two dimensional one. Comparison experiments were carried out between our approaches and others' approaches in some literatures. Preliminary experimental results show that our approaches can effectively describe the texture information of medical images. Furthermore, the image retrieval results are encouraging.

This paper introduces the design and development of a teleimaging diagnosis system by using B/S mode. A detailed design on the telediagnosis process and telediagnosis management is presented, focusing on resolving medical image transmission, management and display in the internet, and is trying to integrate the teleimaging diagnosis system with PACS.

As traditional data management model cannot effectively manage the massive data in traditional Chinese medicine(TCM) due to the uncertainty of data object attributes as well as the diversity and abstraction of data representation, a management strategy for TCM data based on big data technology is proposed. Based on true characteristics of TCM data, this strategy could solve the problems of the uncertainty of data object attributes in TCM information and the non-uniformity of the data representation by using modeless properties of stored objects in big data technology. Hybrid indexing mode was also used to solve the conflicts brought by different storage modes in indexing process, with powerful capabilities in query processing of massive data through efficient parallel MapReduce process. The theoretical analysis provided the management framework and its key technology, while its performance was tested on Hadoop by using several common traditional Chinese medicines and prescriptions from practical TCM data source. Result showed that this strategy can effectively solve the storage problem of TCM information, with good performance in query efficiency, completeness and robustness.

Through integration of medical imaging resources of 12 community hospitals in the region, a community hospital diagnostic image center was established in 6th hospital. This paper describes the design of the structure and mode of data storage of regional PACS system and the establishment of a database of medical imaging, through which the medical imaging diagnostic level in the community was improved significantly. Through the application of regional PACS system, medical resource was saved and patient treatment facilitated.

Since "Budapest Open Access Initiative" signed in 2002, there have been more and more open-access journals coming out on Internet, thus brining the best condition to the researchers. It has made better the phenomenon of not having enough foreign language periodicals in our country. The present author has selected part of free biomedicine periodical websites: High Wire Press; PubMed Central; BioMed Central; BioLine International; Free Medical Journals Site; Scientific Electronic Library; Hindawi; Academic Journals Inc; Biomedical Journals from India. And then, analysis and demonstration are made with respect to the search channels of 3 main free electronic periodical websites. It is the intent of this paper to make things convenient for researchers to get information from the websites quickly.
