Objectives : The purpose of this study is to investigate the therapeutic effects of oriental medical treatment and oriental-western medical treatment on Bell's palsy. Methods : From 1st June, 2006 to 31th August, 2007, 30 Bell's palsy patients who visited the Facial palsy center at East-West Neo Medical Center within 7days of onset and treated for more than 4weeks were randomly divided into two groups. Group A was treated with oriental medical therapy(Acupuncture, Herb, Physical therapy) and Group B with both oriental and western medical therapy(Acupuncture, Herb, Physical therapy, Administration of prednisone). We evaluated the treatment effect of each group with the House-Brackmann Gross Grading System before treatment, after 1week, 2weeks, 3weeks and 4weeks of treatment. Results : After 1week of treatment, Group A showed better performance compared with Group B. After 3weeks and 4 weeks of treatment, Group B showed better performance than Group A. Conclusions : These results proved that combination treatment of oriental and western medicine was more effective than just oriental medical treatment in long term treatment of Bell's palsy. But we discovered that there were no significant differences between the two groups.

Objectives: The purpose of this study is to analysis the clinical study trends on Korean Medicine treatment for Bell's palsy during pregnancy. Methods: Key words such as 'facial palsy', 'Bell's palsy, 'Korean medicine', 'herbal medicine', 'acupuncture', 'pregnancy' were searched through the 'RISS', 'OASIS', 'KISS', 'PubMed' and 'CNKI' databases. Results: Ten clinical studies with 107 patients were selected, and 1 randomized controlled trial and 9 case reports were included as the target studies. In the 9 case reports, the gestational age at the onset of facial palsy was most common in the third trimester (29-42 weeks) in 38 cases (56.7%). The most commonly used Korean medicine interventions were acupuncture, with the most frequently used acupoints being ST4, ST2, ST6, BL2, TE23, LI20, GB1, GB14, SI18, and CV24. The herbal medicine treatment most commonly utilized was Geumgwedanggwi-san (金匱當歸散), which is related to the principles of clearing heat, nourishing blood, and stabilizing the fetus (淸熱養血安胎). Among the 65 participants evaluated using the House-Brackmann facial nerve grading system, 81.5% showed complete recovery to grade 1, while 6% remained at grade 4 with no effect, indicating the efficacy of Korean medicine treatment for facial palsy during pregnancy. All the selected studies reported no abnormalities in the mothers or fetal growth, and all participants who had the reported delivery had full-term childbirth. Conclusions: The effect on Korean Medicine treatment for Bell's palsy during pregnancy had mostly positive results. However, further large, well-designed clinical trials are needed to establish the foundation of Korean Medicine treatment for Bell's palsy during pregnancy.

This essay investigates how the industrialization of the US food system was closely linked to US foreign policy, gender issues, and the rise of consumerism in the Cold War era. While many scholars in American studies and women's studies over the past few decades have paid increasing attention to the interrelationship of gender politics and the media industry in shaping US domesticity, they have seldom studied how and why reading gender issues in relation to environmental discourse in general and the industrialized US food system in particular can help us better understand the complex relationship between environmental and social problems that we are facing today, both collectively and individually. In this context, this essay shows how US national politics have not only created the ideal of American domesticity that promotes traditional gender roles and consumerism at the expense of gender equality, but also negatively affected women's somatic and mental health writ large. By closely examining the cultural implications of Nixon's and Khrushchev's Kitchen Debate in the 1950s alongside newspapers, photographs, advertisements, and Sylvia Plath's The Bell Jar (1963), I argue that reading Cold War consumer culture in relation to the US food system leads readers to see the invisible links between gender politics and today's environmental and social problems in comparative and global contexts.

Objective : This study was aimed to investigate the general features and differences between obesity and skinniness of patients with Bell's palsy. Methods : We measured the sex, age. BMI. pulse diagnosis and HBGS (House-Brackmann Grading System) of 234 patients who were diagnosed with Bell's palsy. Results and Conclusions : The results with statistical significance were as follows (1) The distribution of age revealed that 40s was the most at 30.8 %: (2) The improvement period in facial palsy patients with sub-paralysis was shorter than whole-paralysis. And in one part the more we treated, the shorter the improvement period was: (3) In distribution of fat rate in facial palsy patients, obesity was the most at 61.37%, low weight 15.88%. So we found that the fatter the patients was. the higher the onset rate was: (4) In distribution of pulse diagnosis in facial palsy patients with obesity. the ratio of Xu mai (虛脈) was 67.06%. Shi mai (實脈) 32.94%. The Xu mai was similar to Qi xu (氣虛). So we found that the facial palsy patients with obesity were more Qi xu than with low weight. In distribution of pulse diagnosis in facial palsy patients with skinniness, the ratio of Chi mai (遲脈) was none. Shuo mai (數脈) was most: (5) In distribution of region in facial palsy patients with obesity-Xu mai. the ratio of left was 45.10%, right 54.90%, but this result was not statistically significant.

The ideal method of safety evaluation is to verify results of execution against all possible operations within operating system, but it is impossible. However, the formal method can theoretically prove the safety on actual logic of operating system. Therefore we explain the contents of the art of the safety verification of security kernel, and make a comparative study of various standardized formal verification tools. And then we assigned PVS(Prototype Verification system) of SRI(Stanford Research Institute) to verify the safety of a modified BLP(Bell & LaPadula) model, the core access control model of multi-lavel based security kernel. Finally, we describe formal specification of the revised BLP model using the PVS, and evaluate the safety of the model by inspecting the specification of the PVS.

In this paper, we propose and observe a system that adopts Independent-MCS (Modulation and Coding Scheme) level for each layer in the combined AMC-V-BLAST (Adaptive Modulation and Coding-Vertical-Bell-lab Layered Space-Time) system. Also, comparing with the combined system using Common-MCS level, we observe throughput performance improvement. As a result of simulation, Independent-MCS level case adapts modulation and coding scheme for maximum throughput to each channel condition in separate layer, resulting in improved throughput compared to Common-MCS level case. Especially, the results show that the combined AMC-V-BLAST system with Independent-MCS level achieves a gain of 700kbps in $7dB{\sim}9dB$ SNR (Signal-to-Noise Ratio) range.

In this paper, a numerical study has been carried out to investigate the influence of volute geometries on the performance of a sirocco fan. In order to achieve an optimum volute design and explain the interactions between the different geometric configurations in the volute system, three-dimensional computational fluid dynamics and the 'design of experiment' method have been applied. Several geometric parameters, such as the volute expansion angle, the cut-off position and the bell mouth shape, are employed to improve efficiency and performance. $2^k$ factorial designs were performed to screen the most influential parameters and interactions, and showed that the cut-off position and the bell mouth shape are the most significant parameters. The optimum design was selected as a result of the response surface methodology, and effects of these parameters and their interactions were presented. From the results of computational analyses and experimental data, the performance and efficiency of the sirocco fan were successfully improved. Also, detailed effects of geometric variables of the volute system on the fan performance were discussed.

In this paper, binary pulse-antipodal modulation (2PAM) direct-sequence (DS) ultra-wideband (UWB) system is applied to multiple input multiple output (MIMO) system using vertical bell lab layered space-time (V-BLAST) structure to achieve high-data-rate communications over indoor wireless channels. The relationship between antenna dimension and BER performance of 2PAM DS UWB MIMO system is discussed. In the receiver of UWB-MIMO system, various MIMO detection algorithms such as zero-forcing (ZF), ZF-ordered successive interference cancellation (OSIC), minimum-mean-square-error (MMSE), MMSE-OSIC and maximum likelihood (ML) are comparatively studied.

Objectives : This study was to assess the effectiveness of oriental medical therapy (OM) on acute Bell's palsy, comparing its outcome with that of oriental-western medical therapy (OWM). Methods : Subjects were enrolled atKyung Hee Medical Center from March 2007 to December 2007. We prescribed Igigeopung-san and acupuncture therapy to both the OM and OWM groups, and prednisolone only to the OWM group. Effectiveness was assessed by the House-Brackmann facial nerve grading system (HBGS) and Yanagihara's unweighted grading system (YUGS) every week. Results : There were 31 patients in the OM group and 34 in the OWM group. About grading system scores and weekly score gaps, no significant differences were revealed between the two groups, but statistical significant difference was detected at recovery time. After 2 weeks of treatment, the OM group's HBGS score showed significant difference from baseline score, but the OWM group showed it after 1 week. After 3 weeks of medication, pain was reduced in 22% of OM group patients, but 50% in the OWM group (p=0.028). We made the same comparison study for patients treated within 4 days from onset, but there was no significant difference between the two groups. 3 cases of adverse effect of hyperglycemia were found in the OWM group, which could be due to hyperglycemic side-effect of prednisolone. Conclusion : This work could help us to understand the effectiveness of OM compared to OWM on acute Bell's palsy.

We performed a new high-resolution spectroscopy of AG Vir for 4 nights from 25 March 2004 using the BOES (Bohyunsan Optical Echelle Spectrograph) attached to the 1.8-m reflector at Bohyunsan Optical Astronomy Observatory, and obtained a total of 59 spectra where all orbital phases are covered. To get the radial velocities of the binary system, both method of the CCF (Cross-Co..elation Function)and the BF (Broadening Function) were applied to the analysis of all the observed spectra. From these, the CCF could calculate the radial velocities of the primary star alone, while the BF could determine those of the primary and the secondary components. New absolute dimensions were deduced with the combination of our spectroscopic orbital elements ($K_1=90.5km/s$와 $K_2=258.8$) and the photometric solutions of Bell, Rainger, & Hilditch (1990): $A_1,=1.99M_\bigodot,\;M_2=0.62M_\bigodot,\;R_1=2.21R_\bigodot,\;R_2=1.36R_\bigodot,\;L_1=13.17L_\bigodot,\;and\;L_2=3.47L_\bigodot$. Our absolute parameters are larger and brighter than those derived from Bell, Rainger, & Hilditch (1990). We re-analyzed all the previous radial-velocity curves of AG Vir and, as a result, can see that its system velocity scatters largely up to ${\pm}8km/s$. However, we, at present, cannot determine this as the light-time effect due to the third body, which was suggested as a cause of the orbital period changes by Qian (2001).
