Objectives : The aim of this study was to investigate the effect of oriental medical treatment on Bell's palsy patients receiving chemotherapy. Methods : A clinical study was done on 3 patients who were diagnosed and treated as Bell's palsy at the Dep. of Acupuncture and Moxibustion College of Oriental Medicine Daejeon University. The effects of combined treatment of acupuncture, herbal medicine and physiotherapy were evaluated with Yanagihara's unweighted grading tool. Results : 1. There was significant improvement on Yanagihara score after treating with Gunbiikqi(健脾益氣) method, which was based on pattern differentiation as Hur(虛證). 2. Three patients commonly complained heaviness, dyspepsia, anorexia after receiving chemotherapy and oriental medical treatment showed significant improvement on the symptoms. 3. All three cases received herbal medicine treatment and liver function test. Three cases showed normal range of liver function during and after the treatment. Conclusions : Oriental-medicine treatment did not damage in liver function and showed significant improvement on Bell's palsy in patients receiving chemotherapy. But it is considerd that we need to keep limits in getting enough patients.

Purpose: This study was to confirm the effect of acupressure on the emesis control and the weight change among pediatric cancer patients receiving anti-cancer chemotherapy. Method: Forty pediatric cancer patients, receiving the induction stage of chemotherapy with MTX and vincristine, were divided into control(n=20) and the intervention group(n=20). Both groups received regular anti-emesis medication, but the intervention group was added acupressure maneuver for 5 minutes on P6 point for 3 times a day for 5days: before chemotherapy, lunch and dinner by investigator during the hospitalization and by mother at home. The instruments for this study were Rhode's(1986) Index of nausea, vomiting and retching(INVR), Cas electric scale and pamphlet developed by researcher. Result: Significant differences in the degree of nausea and vomiting were observed between the control and the intervention group as measured by INVR(t=4.73; p=.01). Repeated measures ANOVA also shows that the group effect was significant(F=22.39, P=.01) as was the time effect(F=380.35, P=.01). The group by time interaction was also significant(F=5.27, P=.01). Acupressure maneuver was apparently effective in reducing the degree of chemotherapy-induced nausea and vomiting. There were also statistically significant weight loss noted in the control group than the intervention group(t=5.42, p=.01). Conclusion: Acupressure on P6 point shows an effective adjunct maneuver in reducing the degree of nausea and vomiting and conserving the weight in pediatric cancer patients. Therefore, it is proposed that acupressure should be applied as supportive nursing intervention strategies to relieve chemotherapy induced nausea and vomiting and to prevent weight loss in pediatric cancer patients.

In this paper, we make plans for facilities, the 8-VSB DTV transmission system, installed in the near future, based on presently NTSC TV operating it. First of all we estimate transmission power for analog NTSC, digital 8-VSB terrestrial broadcasting and the effective condition of optimal receiving power result from it. It's also to estimate optimal receiving condition by using Longley-Rice's Field Strength calculating method that is to guess a profile between transmitting station and many receiving points. The 8-VSB DTV Propagation aims to high-speed transmission rates of 19.39Mbps datum to enable HDTV(High Definition Television) at NTSC 6MHz bandwidth. First of all, an optimization of field strength between transmission station and receiver must deal with considerable. Because of these reasons, 8-VSB DTV transmission needs effective extension for NTSC TV service coverage. Finally we present the transmitting output that is expected in changing NTSC VHF to DTV UHF for maintaining the transmitting output of NTSC TV that is equal to 8-VSB DTV in service coverage.

Purpose: The purpose of this study was to identify factors influencing chemotherapy-induced peripheral neuropathy among colorectal cancer patients receiving oxaliplatin. Methods: A total of 132 patients hospitalized for chemotherapy were surveyed at K University Hospital in Seoul, Korea. This study was a descriptive causal relationship study using a self-report questionnaire survey method. Correlation and multiple regression analysis between the factors were performed using SPSS 18.0. Results: The regression model was significant (F=31.64, p<.001), which meaned that the experience of chemotherapy-induced peripheral neuropathy among the participants was statistically significant. The factors influencing the chemotherapy-induced peripheral neuropathy were depression (${\beta}=.34$, p<.001), followed by anxiety (${\beta}=.32$, p<.001), medical staff support (${\beta}=-.17$, p=.037) and the level of knowledge of anticancer drugs (${\beta}=-.16$, p=.045). The explanatory power of these factors on the chemotherapy-induced peripheral neuropathy of colorectal cancer patients was 69%. Conclusion: The factors influencing the chemotherapy-induced peripheral neuropathy of colorectal cancer patients receiving oxaliplatin were identified as depression, anxiety, level of knowledge of anticancer drugs and medical staff support.

In this paper, we propose the assistance method to enable safe driving through analysis of dangerous driving behavior using real-time alarm by vehicle speed, azimuth data and smartphone. For this method, smartphone is receiving driving data from digital tachograph using communication. Safe driving habit is a very important issue to commercial vehicle because that driver's long time driving than other vehicle type driver. Existing methods are very inefficient to improve immediately dangerous driving habits during driving because proceed driving behavior analysis after the vehicle operation. We propose the new safe driving assistance method that can prevent traffic accidents by real-time and improve the driver's wrong driving habits through real-time dangerous driving behavior analysis and notification the result to the driver. We have confirmed that the method in this paper will help to improve driving habits and can be applied through the proposed method implementation and simulation experiment.

The purpose of this study was to investigate utilization and storage management practice of the frozen and refrigerated foods in school foodservice. 222 dietitians employed in school foodservice were surveyed. In school foodservice, the refrigerated stock farm products and seafoods (78.3%) were more used rather than frozen products (47.5%). According to school foodservice characteristics, the refrigerated meats including dairy products were more frequently used in elementary and middle schools than high school foodservice. On the other hand, the foodservice in high school used more frozen seafoods and processed foods than elementary school did. The data also showed a tendency for the contracted foodservice using more frozen meats and seafoods rather than refrigerated products when comparing with the self-operated foodservice. In terms of receiving conditions, storage methods and storage time, the result indicated that frozen or refrigerated products were often delivered at inappropriate temperature. Especially some products which were needed to be shipped and stored at refrigerated temperature such as mollusks, were delivered and kept at room temperature. The most frequently used thawing method were running water (56.9%), however, the frozen products were often sitted at room temperature for the purpose of thawing. According to the results, several inappropriate handling processes for frozen and refrigerated products were found in school foodservice. In order to improve handling process for frozen and refrigerated products, recognition of food handlers' weakness about storage and distribution, development of radical standards for receiving conditions, storage and thawing methods should be debated.

We propose an adaptive shaping controller equipped with the technologies of shaping and buffering VoIP packets arriving at the receiving end by the CAM-type controller. In order to conceal interarrival packet delay variation, the conventional jitter buffers force them to be too large, thereby causing the audio quality to suffer excessive delay. However, by using our proposed method, the delay caused by shaping operation dynamically increases or decreases on the level of jitter that exists with in the IP network. This makes the delay accommodates adaptively the network jitter condition. The less jitter network has the fewer delay the shaping controller requires for jitter elimination. And the CAM-type method generally makes the shaping operation faster and leads to processing packets in as little time as can. We analyse the packet loss and delay performance dependency on the average talk ratio and the number of jitter buffer entries in shaping controller. Surprising, we show that the average delay using our shaping controller is about 70msec. This performance is much better than with the delay equalization method which forces the receiving end to delay about 60msec.

It is important to know phase offsets of PN (Pseudo Noise) sequences in spread spectrum communications since the acquisition is equivalent to make a phase offset between a receiving PN sequence and a PN sequence of local PN generator be identical. In this paper, a phase offset enumeration method for PN sequences with error detection, and its application to the synchronization are proposed. The phase offset enumeration far an n-tuple PN sequence and its error detection are performed when one period of the sequence is received. Once the phase offset of the receiving sequence is calculated, we can easily accomplish the synchronization by initializing shift registers of a local PN generator according to the phase offset value. The mean acquisition time of the proposed synchronization method is derived analytically, and we see that the method acquires very fast acquisition in the high SNR (Signal-to- Noise Ratio) environment.
