Objectives: The purpose of this study was to investigate the current trends in research on pharmacopuncture in Korea since 2007. Methods: A literature review was performed by using the search engines 'Science and Technology Society Village', 'Korean Studies Information Service System', 'National Discovery for Science Leaders', and 'Oriental Medicine Advanced Searching Integrated System' in Korea from January 2007 to December 2013. Searched key words were 'pharmacopuncture', 'herbal acupuncture', 'aqua-acupuncture', and 'bee venom'. Finally, we selected 457 papers, including Korean experimental studies and clinical studies. Selected papers were classified according to year of publication, type of pharmacopuncture, disease & topic, research type and the publishing journal. Results: One hundred fifty pharmacopunctures were studied in 457 papers. Single compound pharmacopuncture was the most studied pharmacopuncture in experimental studies while animal-based pharmacopuncture was the most studied pharmacopuncture in clinical studies. Bee venom placed first among the various pharmacopunctures, followed by placenta, sweet bee venom, mountain-ginseng, and anti-inflammatory pharmacopunctures. Experimental research on pharmacopuncture has fallen since 2007 when 55 papers were published. However, clinical research has been increasing steadily. In clinical studies, case reports were numerous than randomized clinical trials (RCTs). Musculoskeletal diseases were the most frequently-treated diseases in studies on pharmacopuncture; among the musculoskeletal diseases, rheumatoid arthritis was the most frequently-treated disease in experimental studies and low back pain was the most frequently-treated condition in clinical studies. Since 2007, 45 different journals have published studies on pharmacopuncture, with the Journal of the Korean Acupuncture and Moxibustion Medicine Society having the largest number of papers on pharmacopuncture and the Journal of Pharmacopuncture the second largest number. Conclusion: The trends in research on pharmacopuncture published in studies from 2007 to 2013 were similar to those in studies published before 2006. Many studies on pharmacopuncture focused on bee venom and musculoskeletal diseases. Additional studies on diverse types of and indications for pharmacopuncture are needed.

Objectives This study aims to review and summarize existing evidence on moxibustion treatment for cancer patients. Methods Literature published until May 2015 in international journals were searched on PubMed, CAJ (CNKI-Medicine), NDSL (National discovery for science leaders), Sage Journal, ScienceDirect, Taylor&Francis Online (HSS), and Wiley Interscience (including Blackwell); and articles in Korean journals were searched on Korean Studies Information Service System (KISS), DBPIA, E-Article, KSI e-book, New article, Korea Institute of Science and Technology Information (KISTI), and Kyobo scholar. Results We analyzed 65 relevant studies. The number of studies conducted annually has increased and most are conducted in Korea and China. Moxibustion decreases the side effects of palliative treatment, thereby synergizing with anticancer treatment; it also improves the immune system, reduces tumor factors, and relieves symptoms. The mechanism of moxibustion is multi-fold: thermo, chemo, aero and kinetic. Only the kinetic effect is not significant. It also needs a complement to moxibustion because of harmful smoke. Conclusions Thus, the effect and mechanism of moxibustion in cancer patients was reviewed. There is an unmet need to develop a model of moxibustion and test it based on Korean medicine.

This article reviews the recent activities of field testing and application of superconducting fault current limiters (SFCL) based on high-temperature superconductors (HTS). The review particularly focuses on the trends in the field tests in terms of the technical aspects and commercial activities of the SFCLs. Stimulated by the discovery of HTS, numerous research and development activities have been conducted worldwide for SFCLs operating from distribution voltages to transmission voltages. Different types of SFCLs have been developed and field-tested. Consequently, more than 20 field tests and applications have been performed on real grids worldwide while supplying electric power to the customers. These field tests have not only provided the track records of the operation experiences including the problems and maintenance during operation, but also proved their current limiting capabilities against real faults, rendering this new technology highly viable. Through these activities, the following trends in the status of field testing and application are observed. Resistive-type SFCLs with HTS-coated conductors were dominantly used in the most recent field tests. This implies that the resistive type is technically more mature than the other types. Bus-bar coupling and transformer feeders were the major application locations. It is of importance that most of the field applications were conducted as R&D projects. A relevant change from the R&D stage to the application stage is shown as recently deployed SFCLs are expected to be under long-term operation and commercial service. Here, we review the installation of these SFCLs by substation. This review also discusses the recent activities for their commercial applications.

With the discovery of WooJam JabJeo, Jang-Taegyung[1809~1887] was highlighted as a noted doctor who won fame in the neighborhood of Gwangju, but with 'WoodJam Mango' seeing the light of day, this study was able to confirm the appearance of a literary man enjoying a reputation enough to sway literary circles with his writing of poems. It's possible to confirm his past related to medical service only until age of 42, which is because description in "WooJam JabJeo" came to a halt there. The situation is that the contents of 'WooJam Mango' started from age of 46 and were carried on even until after his death by his followers. Therefore, there exists a very intense impression that he might have put a focus on the life as a literary man ever after his mid-40s. and considering that he breathed his last at the age of 79, it's not difficult for us to estimate that his life was predominantly a series of literary activities rather than a health care provider. The place names appearing in "WooJam JabJeo" and "WooJam Mango" are limited to today's Jeonlanam-do, and this researcher would say that the through-composed poems, which sang of the beauty of Gwangju area scenery are the works, deserve to get a spotlight in local history even today. Through the above discussion, this study could prove that WooJam is a flawless figure enough to represent Gwangju and Jeonlanam-do as a health care provider and a literary person as well.

MANET is a dynamically reconfigurable wireless network with no fixed infrastructure (base station, or AP). In order to provide the data service in MANET, we need an efficient routing protocol to deliver the data to the wanted destination at a mobile node. A method of routing protocols called reactive routing protocol has recently got attention because of their low routing overhead. But a method of flooding broadcasts the packet to all of its neighbors. For this reason, each of the node has high routing overhead to route and keep path discovery. Accordingly in this paper, I propose an adaptive flooding scheme using N-hop look-ahead in MANET, md an optimal N value of doing flooding the packet to limited area. Because of being basically ignorant about topological changes, each of the node did not spontaneously cope with path alteration. But an efficient flooding scheme applying N-hop look-ahead is more resilient to topology changes than traditional algorithms. And also with this efficient flooding scheme, the simulation results demonstrate excellent reduction of routing overhead.

Background: This study investigated current research trends in bee venom acupuncture in Korea. Materials and methods: The literature in Korea was reviewed using the search engines Science and Technology Society Village, Korean Studies Information Service System, National Discovery for Science Leaders, and Oriental Medicine Advanced Searching Integrated System. The keywords searched were "bee venom," "apitoxin," "apitherapy," and "bee sting." We selected 412 studies, which included Korean literary studies, experimental studies, and clinical studies. Results: We classified them by publication year, research type, disease and topic, and quality assessment. Among bee venom-related studies, clinical studies (235 studies) outnumbered experimental studies (149 studies) and literary studies (28 studies). Nineteen experimental studies concentrated on the theme of "anticancer." In the type analysis of clinical studies, lumbar disorders comprised 45 of 235 studies, followed by the effect on body. Forty-two randomized controlled trials (RCTs) have been published from 2003 to date (2015). Twenty-two studies used appropriate randomization methods. Fourteen studies had a Jadad score of 4-5 points; 15 studies, 1-3 points; and 13 studies, 0 points. Conclusions: Bee venom treatment is based on Korean traditional medicine theory. Numerous research studies suggest its effectiveness. Effort and academic approach on bee venom are expected to receive a positive evaluation.

Objective : Radiodermatitis is a common sequelae in 95% of patients receiving radiation therapy, which is important to be well managed as it can affect the patient's quality of life as well as the cancer treatment schedule. The aim of this study is to review and summarize the interventions available for the treatment of acute radiodermatitis, including traditional Korean medicine, and to propose treatment algorithms for clinicians. Methods : To collect studies about managements for radiodermatitis, domestic and foreign database were used such as Korean journal of traditional knowledge portal (KTKP), Korean studies information service system (KISS), national discovery or science leaders (NDSL), and oriental medicine advance searching integrated system (OASIS), Pubmed, Google scholar and Scopus. Results : Thirty-two studies were selected. There were nine studies on usual care and dressing, eleven studies on chemical agents, two studies on biological preparations, and ten studies on herbal medicines. Conclusion : Hygienic options and dressings have proved to be useful in the management of radiodermatitis. Chemical agents such as corticosteroid, statin, and topical antibiotic agent have proved to alleviate symptoms and severity, regenerate damaged skin, and prevent secondary infection. In biological preparations, EGF (epidermal growth factor) and GM-CSF (granulocyte-macrophage colony-stimulating factor) could be used to protect skin and prevent radiodermatitis. For herbal medicines, Calendula, catechin, β-sitosterol, and Jaungo (紫雲膏) may be effective for symptoms including pain, itching, and burning sensation induced by radiation therapy. Because of some research with conflicting results, further studies are needed to propose an algorithm for more optimal treatments.

Recently data growth rates are growing exponentially according to the rapid expansion of internet. Since users need some of all the information, they carry a heavy workload for examination and discovery of the necessary contents. Therefore information retrieval must provide hierarchical class information and the priority of examination through the evaluation of similarity on query and documents. In this paper we propose an Multi-class support vector machines model based clustering for hierarchical document categorization that make semantic search possible considering the word co-occurrence measures. A combination of hierarchical document categorization and SVM classifier gives high performance for analytical classification of web documents that increase exponentially according to extension of document hierarchy. More information retrieval systems are expected to use our proposed model in their developments and can perform a accurate and rapid information retrieval service.

In this paper, we tried to enable a mobile device as a resource to access to mobile grid networks. By advanced Internet techniques, the use of mobile devices has been rapidly increased. Some researches in mobile grid computing tried to combine grid computing with mobile devices. However, according to intrinsic properties of mobile environments, mobile devices have many considerations, such as mobility management, disconnected operation, device heterogeneity, service discovery, resource sharing, security, and so on. To solve these problems, there are two trends for mobile grid computing: a proxy-based mobile grid architecture and an agent-based mobile grid architecture. We focus on a proxy-based mobile grid architecture with IP-paging, which can easily manage idle mobile devices and grid resource status information. Also, we use SIP(Session Initiation Protocol)to support mobility management, mobile grid services. We manage variation of mobile device state and power by paging cache. Finally, using the candidate set and the reservation set of resources, we perform task migration. The performance evaluation by simulation, shows improvement of efficiency and stability during execution.
