Objectives The purpose of this study was to survey the status of clinical use of a computerized tongue diagnosis system (CTDS) Methods We searched domestic/international articles using the CTDS from online medical databases including OASIS, NDSL and pubmed. We selected articles on clinical application or reliability of CTDS but excluded articles on mechanical design or software programming for developing a new CTDS. Finally we found 15 articles and classified the articles according to the study purpose. Results Out of the 15 articles, 8 were focused on the clinical application including halitosis, cold/heat syndrome, lung cancer, xerostomia etc. Other 5 articles were aimed at evaluating and improving reliability of CTDS. The other 2 articles were studied for development of differential diagnostic criteria on tongue coating thickness. Conclusion We found out that until now the researches on clinical application of CTDS mainly had been performed for producing a variety of CTDSs. Considering the importance of the tongue color in the traditional Korean medicine, we suggest that at first standard operating procedure for CTDS be developed and researches to develop differential diagnostic criteria on tongue body/coating color be performed and then explore its applications.

최근 스마트폰의 급속한 보급에 따라 기지국과 같은 기반구조를 사용하지 않은 MANET(Mobile Ad-Hoc Network)의 활용이 늘어날 것으로 예상되며, 인터넷 전화로 알려진 VoIP는 MANET의 주요 응용서비스 가운데 하나가 될 것으로 생각된다. 한편, 최근 문제점이 심각하게 부각되고 있는 정보침해의 경우, MANET에서도 예외일수는 없다. 특히, 군사적 목적이나 구난 구조와 같은 긴급 목적으로 사용이 가능한 MAENT에 대한 정보침해는 다른 네트워크에 비해 매우 치명적인 결과를 초래할 위험성을 내포하고 있다. 본 논문에서는 이런 문제점을 규명해보고자 블랙홀 공격이 있는 MANET에서 정보침해가 전송성능에 미치는 영향을 분석해 본다. 분석대상 서비스로는 VoIP 트래픽을 가정하였으며, 분석방법으로 NS-2를 사용한 컴퓨터 시뮬레이션을 활용한다.

We report on the relationship between output current for quadrant photodetector (QPD) and bias voltage in silicon-based p-i-n (positive-intrinsic-negative) QPD examined using millisecond pulse laser (ms pulse laser) irradiation. The mechanism governing the relationship was further studied experimentally. The output current curves were obtained by carrying out QPD under different bias voltages (0-40 V) irradiated by ms pulse laser. Compared to other photodetectors, the relaxation was created in the output current for QPD which is never present in other photodetectors, such as PIN and avalanche photodetector (APD), and the maximum value of relaxation was from 6.8 to 38.0 ㎂, the amplitude of relaxation increases with bias value. The mechanism behind this relaxation phenomenon can be ascribed to the bias voltage induced Joule heating effect. With bias voltage increasing, the temperature in a QPD device will increase accordingly, which makes carriers in a QPD move more dramatically, and thus leads to the formation of such relaxation.

Objectives : This study aims to examine the efficacy and application of Cannabis according to its parts. Methods : Contents on efficacy, treatment, and application of Cannabis in Material Medica and other texts of East Asian Medicine were collected and interpreted to deduce each characteristic. Results : Cannabis was found to be applicable to various wind symptoms and wind stroke, various pain and injuries, skin diseases, blockage or leaking of urine or feces, disease related to genitalia and anus, chronic ague, women's disease related to menstruation, birth, pregnancy, and to have the effects of heightening perceptive and sensory organs, detoxification and anesthesia, stimulating hair growth, and eradicating parasites. It drives out wind-heat pathogenic qi, circulates qi and blood, which allowed it to be applied not only to blockages but to symptoms of leakage. In other words, Cannabis was used when both excess and deficiency diseases were present, the former caused by acute blockage and the latter accompanied by stagnation. Conclusions : Based on the findings of this study, future researches on the efficacy and application of Cannabis could be done more systematically. In line with recent trend of wide application of medical Cannabis, we hope for it to be more actively used in the field of East Asian Medicine based on objective evidence.

Many farmers apply cattle slurry on grassland, often in excess of crop N requirements, resulting in groundwater contamination. Our research objective was the development of grassland management systems that reduce undesirable sideeffects on other compartment of the ecosystem. Field experiment was conducted during 1991~1993 on sandy loam soil at AllgZiu south western Germany. Different sets of conditions were tested such as : zero fertilization, reduced sluny application$(l20kg N ha^{-1}yr^{-1})$, intensive sluny application(conventional sluny application, $240kg N ha^{-1}yr^{-1}$). The plots of the reduced slurry application had no significant effect on dry matter yields, digestible dry matter and net energy of herbage. Dry matter yield of zero fertilization was significantly lower than that of usual slurry application, however the content of Ca and Mg in herbage tended to increase. We conclude that reduced sluny application can be applied on grassland without adverse effects on dry matter production and quality of herbage.

The purpose of this study was to measure the oral temperature, skin temperature, and subjective discomfort according to the application time of ice bag on thigh, head, and abdomen. This study was also intended to suggest nursing principles about ice bag application by exploring the recovery time of skin temperature after the removal of ice bag. The design of this study was $8{\times}3$ factorial design with one sample repeated measure. Here, the application time of ice bag(criteria, 5min, 10min, 20min, 30min, 40min, 50min, 60min) and the application site of ice bag(thigh, head, abdomen) were independent variables. The subjects were 10 university woman students, and data collection was made from July, 1 to August 30, 1992. Rubber ice bag halfly filled with ice was covered with towel and applied on thigh, head and abdomen in other three days. Before applying the ice bag, oral temperature and skin temperature were checked for criteria. After ice bag was applied, skin temperature, oral temperature and VAS score were checked at first 5 minutes elapsed, and every 10 minutes until 60 minutes. After that, ice bag was removed, and oral temperature and skin temperature were also measured every ten minutes until 60 minutes. In this study, skin temperature and core temperature were measured by thermistor probe, and subjective discomfort was measured by 200mm VAS (Visual Analogue Scale). Some of the findings were as follows : 1. There were significant differences in skin temperature among the three application sites of ice bag as time go by. It was most decreased to $15.87^{\circ}C$ in thigh, and $19.47^{\circ}C$ in abdomen at 50 minutes after the application of ice bag, whereas $26.1^{\circ}C$ at 40 minutes in head. Before the application of ice bag, skin temperature showed significant differences in three sites, so that they were compared after the criteria was covariated. In other words, there was significantly more decrease of skin temperature in thigh and abdomen than head, after ice bag was applied for 20 minutes and more. 2. There was no significant difference in core temperature among the three application sites of ice bag during the time of application 3. There was no significant difference in subjective discomfort (VAS) among the three application sites of ice bag. 4. After the removal of ice bag, the recovery of skin temperature was significantly different in three sites during first 30 minutes. In head, skin temperature came up to criteria at 30 minutes after the removal of ice bag, but it was not recovered In thigh and abdomen even 60 minutes elapsed. 5. After the removal of ice bag, there was no significant difference in oral temperature among the three application sites of ice bag. 6. There was significant correlation between the skin temperature and VAS score only in thigh. In conclusion, it is suggested that head in more suitable site for the application of ice bag if it is used for the relief of fever or pain. When we apply ice bag on thigh or abdomen for the relief of pain, careful attention is required.

This study was conducted in order to determine the effect of Paraffin Therapy on release of pain, skin temperature and range of motion with joint diseases. This study was performed on 42 patients with general joint diseases and 21 patients with degenerative joint diseases. All the subjects were randomly assigned to three groups with 21 each. The experiment had been done from June, 1. 2002 to September, 30. 2002, in two general hospitals and a social welfare center using Digital Thermometer Kane-May KM330 and VAS(visual analogue scale). Each pint was measured in terms of skin temperature, pain scale and ROM(range of motion). The results of the experiment are as follows : 1. In application of three different heat modalities (Paraffin bath, Infra red, Hydro pack) on the Knee, Ankle, Elbow pints of the subjects for 30 minutes, the elevation of skin temperature and the reduction of pain scale were found to be significantly different. When checked right after the 30 minutes' application, the Infra red resulted in a higher degree elevation of skin temperature than two other modalities, while Paraffin bath resulted in the highest degree of the elevation of skin temperature when it was checked one hour after the application was over. It means that Paraffin bath lasted longer than the other two modalities(F=14.691, p<.000). 2. With Paraffin bath application, pint pain was reduced significantly both in 30 minutes and one hour checks(F=20.675, p<.001). 3. In terms of ROM(range of motion) increase, didn't seem to have any significant differences in 30 minutes and one hour. The results suggest that Paraffin therapy be helpful in maximizing th effects on pint diseases. I strongly suggest that further studies be done on other pints and muscle diseases using Paraffin bath in different methods of applying the therapy.
