Background : In this paper patient outcomes research is going to be reviewed and described, to be compared with relevant studies, and to consider the application in Korea. Methods : We compiled and reviewed the articles and materials related to patient outcomes research especially by PORT(Patient Outcomes Research Team) and rearranged them for seeking the main point and comparing with relevant studies. Results : Patient outcomes research emphasizes patient outcomes as well as conventional clinical outcomes. It is prospective study observing effectiveness in real situation instead of efficacy in ideal condition. Patient outcomes research comprises of 6 fields ; literature review and meta-analysis, use of claims data, decision modeling, outcomes assessment, cost of care, dissemination of research findings. SAA(small-area variations analysis), appropriateness study and clinical practice guideline are connected with patient outcomes research. Conclusion : In view of the fact that current medical policy in Korea is shifting its focus from accessibility to the improvement in quality and cost containment, and is stressing patient-based research, patient outcomes research is one direction for which the medicine is accountable and assessable. Considering that the number of patient receiving medical treatment in Korea is higher than the West, patient outcomes research has competitive power as against the West.

In this study physical and chemical characteristics of rice straw ash (RSA) were analyzed in agricultural by-products such as the characteristics of soil pH, electric conductivity (EC), total phosphorus (T-P), available phosphate (Avail-P), and cation exchange capacity (CEC). The results showed that RSA is of mainly C in 95.74% and followed by Si > Al > P > Mg > K > Ca. The pH of RSA was high near 11 and the T-P concentration was $2,322.38{\pm}10.35mg/kg$. The specific surface area of RSA was $123.50m^2/g$, which was much lower than that of biochar. The X-ray diffraction (XRD) analysis indicated that RSA were C and Si based crystalline. TCLP and KSLT test results implied that the heavy metal concentrations were below the environmental standards and would not impose the risks. T-P concentration increased from $225.59{\pm}12.69mg/kg$ to $593.39{\pm}17.36mg/kg$ along with RSA mixing ratio to soil from 0% to 15%. Both pH and EC values were increased with the increase of RSA ratio. The changes in Avail-P and CEC were not when RSA mixing ratio was 1%. whereas the Avail-P concentration was slightly increase when the mixing ratio was more than 5%. Additional investigation considering receiving soil characteristics based on the results of this study would help effective application of RSA to soil.

As the demands in a wireless network are recently increasing, it is necessary to promote the power efficiency of a wireless terminal, and to reduce the overhead of a network. To resolve such problems, we propose the paging technology and the structure of paging area with the joint access point in HPi (High-speed Portable Internet) network, which is being studied as the domestic next-generation IP packet data network. The application of the paging technology to the HPi network possesses the advantage of reducing the registration cost while a terminal in dormant state moves around, and the reporting cost of the terminal's location by the joint access point. The technology suggested in this paper causes the advantages that it promotes the power efficiency in user's point of view while it reduces the network overhead and makes the easy rearrangement of joint APs according to the changes of users' moving pattern in the network manager's point of view.

CCSDS Standard is widely used in international space telecommunication area. In this standard, Encryption is realized using a unique hierarchical encryption protocol and satisfied security requirements of communication channels. For synchronization, encryption sync is attached in the beginning of encrypted data. But exceptional case(timing jittering, abnormal system shutdown, etc.) is occurred, receiving equipment cannot decrypt received data. In this paper, we propose a SES Alarmed link encryption synchronization method for sending warning signal to the transmitter when some problems have been occurred during the transmission and we also suggest optimum conditions for SES Alarm signal through performance analysis.

The speech recognition is an active research area in the human computer interface (HCI). The objective of this study is to control digital devices with voices. In addition, the mouse is used as a computer peripheral tool which is widely used and provided in graphical user interface (GUI) computing environments. In this paper, we propose a method of controlling the mouse with the real-time speech recognition function of a smartphone. The processing steps include extracting the core voice signal after receiving a proper length voice input with real time, to perform the quantization by using the learned code book after feature extracting with mel frequency cepstral coefficient (MFCC), and to finally recognize the corresponding vowel using hidden markov model (HMM). In addition a virtual mouse is operated by mapping each vowel to the mouse command. Finally, we show the various mouse operations on the desktop PC display with the implemented smartphone application.

Objectives : The purpose of this study is to report a 67-year-old male patient with Herpes zoster(caseI) and a 38-year-old female patient with Herpes zoster(caseII), whose symptoms were relieved after Korean medicine treatment alone. Methods : Both patients took Yeonryeonggobondan and Pyungwee-san daily. Everytime they came to the hospital, they received acupuncture treatment, Hwidam's Su-Gi therapy and External Gigong Therapy. Acupuncture was applied by gall bladder seunggyeok(膽勝格, GB-), spleen jeonggyeok(脾正格, SP+), large intestine seunggyeok(大腸勝格, LI-) of Saam's Acupuncture Method. Hwidam's Su-Gi therapy was applied on neck. External Gigong Therapy was applied on skin lesion area. the patients' symptoms were evaluated with photographs and VAS. Results : The results were as follows: 1. In the case of a 67-year-old male patient, it took 14 days to recover the skin lesions and to reduce the pain after treatment started. And he visited 13 times during that period. 2. In the case of a 38-year-old female patient, it took 23 days to recover the skin lesions to reduce and the pain after treatment started. And she visited 10 times during that period. 3. Intensive treatment early in treating herpes zoster helped to shorten the treatment period. 4. Taking Yeonryeonggobondan and Pyungwee-san and receiving acupuncture treatment(SP+) can help to improve immunity and recover skin lesions in herpes zoster diagnosed with spleen deficiency with dampness encumbrance(脾虛濕困) and blood stasis due to qi stagnation (氣滯血瘀). 5. The combination of acupuncture treatment(GB-) and External Gigong Therapy was effective in controlling pain. 6. External Gigong Therapy is considered to be effective for the recovery of the skin as well as the pain of the herpes zoster. Conclusions : Korean medicine treatment alone has a great effect on the above two patients with herpes zoster. I hope the active research about Korean medicine treatment will be done not only for herpes zoster but also for various intractable pain diseases.

Over the last 50 years, a number of antibiotic agents have been developed and clinically used in the area of infectious diseases. Due to antimicrobial resistance problems and increasing health care costs, the rational use of antibiotics has been required. As a drug of choice to treat infections caused by MRSA, vancomycin has been extensively prescribed since the late 1970's. Recently, reports of vancomycin-resistant organisms such as VRE and VRSA have been increased to draw medical concerns. The objectives of this study were to evaluate the rational use of vancomycin and the appropriateness of the Restrictional Program of Antibiotic Utilization (RPAU) which has been operated at Samsung Medical Center. A retrospective chart review was performed in 132 hospitalized patients treated with vancomycin in the surgery departments from. January to June 1998. The guidelines of ASHP and HICPAC for vancomycin were modified and used as our criteria to determine the vancomycin DUE. In one hundred out of the patients, uses of vancomycin were approved by the Department of Infectious Diseases (DID) based on the RPAU. Vancomycin was appropriately used in $62.5\%$ of the 100 patients according to the criteria of justification of use, while $60.0\%,\;60.0\%,\;79.0\%,\;and\;51.0\%$ of the patients showed appropriate according to those of lab reports such as applicable culture obtained, pretreatment SCr, WBC and serum drug concentration monitoring, respectively. Although the rest 32 patients were not approved to receive vancomycin by the DID, twenty two percent continued receiving vancomycin treatment. This might result from the fact that the RPAU was started not before the use of antibiotics but in the middle of antimicrobial therapy. Continual education should be provide to the related health professionals and the RPAU should be simultaneously modified in order to increase the rate of appropriate uses of antibiotics.

This paper presents the reflection and transmission measurements conducted at the 60GHz suitable to provide a high speed wide band service. Mean received power and standard deviation are calculated and used to compare the characteristics of radio wave propagation to the various obstacles between transmitting and receiving antennas at the frequency. The results show that the transmitted signal strength by the steel door and copper plate are about 40dB lower than in free space, those by the rubber plate, glass and styroform are about 3dB lower than in free space. Also, the re(looted signal strengths at the 60 degree grazing angle show that in case by the partition is about 23dB lower, by the surface of a wall is about 6dB lower than by the copper plate. The presented results can be used for the design of 60 GHz picocell communication network that the reflected and transmitted waves affect to the service area.
