Objective: This study is to explore the various aspects of the fatigue perceived by patients with Bell's palsy Method: 33 patients who were diagnosed as Bell's palsy were sequentially interviewed and examined Results: The results were as follows 1. The mean average fatigue score of subjects was $1.79{\pm}0.41$ : the physical fatigue revealed the highest value with a mean of $1.84{\pm}0.50$, followed by neurosensory fatigue with a mean of $1.77{\pm}0.42$, psychological fatigue with a mean score of $1.76{\pm}0.54$. 2. With the respect to the general characteristics of subjects, there were statistically significant differences in the patients' fatigue perception by age and the amount of sleeping time. Conclusions: We needed the further study about the relation between fatigue and Bell's palsy

An experimental study has been performed on the effect of baffle parameters on shell -side heat transfer in a conventional shell-and-tube heat exchanger. The baffle spacing distance and the number of baffle were varied to investigate the behavior of unequal baffle spacing correction factor which is appeared in the Bell Delaware method for prediction of the shell-side heat transfer coefficient. It was obvious that heat duties obtained from the experiment significantly deviated from those calculated by the conventional Bell-Delaware method. A new correlation of the unequal baffle spacing correction factor was developed. It was shown that the new correlation improves the accuracy of the Bell-Delaware method considerably. This result may induce the use of the Bell-Delaware method in developing a computer software for design of shell-and-tube heat exchangers.

Facial nerve palsy is not a serious disease, but it can be both upsetting and disabling for patients. More than half of the lesions of facial nerve palsy fall into the category termed Bell's palsy. It is very rare to find a representative case of bilateral Bell's palsy. Here we report the changes of infrared thermographic findings in bilateral Bell's palsy treated with a stellate ganglion block (SGB). A 45-year-old female patient who had a right facial palsy which developed 2 weeks before. Steroid administration and acupuncture was not effective and so she was referred to pain clinic. The right facial palsy was cured after 19th right SGB. Twenty eight days after the onset of the right facial palsy, left facial palsy also developed and cured completely with a left SGB. Serial infrared thermograms were performed. The hypothermias on the affected side improved symmetrically by the end of the treatment.

Objectives : This study was to investigate the efficacy of Scolopendrid pharmacopuncture on relieving postauricular pain which was an early symptom of Bell's palsy. Methods : Clinical observation was done on 32 patients diagnosed with Bell's palsy in Cheon-ahn Oriental Medical Hospital of Daejeon University from November 11, 2011 to August 31, 2012. The patients were divided into 2 groups; group A received conventional treatment alone and group B received conventional treatment as well as Scolopendrid pharmacopuncture treatment. Results : 1. Scolopendrid pharmacopuncture group(group B) exhibited significantly reduced postauricular pain compared to conventional treatment group(group A). 2. Group B had significantly shorter duration of postauricular pain than group A. 3. Group B group showed better outcome than the group A but the difference was not significant. Conclusions : Scolopendrid pharmacopuncture shows a significant beneficial effect on postauricular pain as an early symptom of Bell's palsy.

Purpose: This study was done to evaluate the effects of Doin Gigong Exercise on the Recovery from Facial Paralysis, pain and anxiety in patients with Bell's palsy. Methods: A nonequivalent control group posttest-only non-synchronized design was used for this study. Participants were contacted at the oriental medicine ward of D hospital in Busan and assigned to either the experimental group (25) or control group (25). Collected data were analyzed for changes in recovery from facial paralysis, in pain and in anxiety between pre and post Doin Gigong Exercise. Data analysis was done using t-test, Fisher's exact test, $x^2-test$ with the SPSS 12.0 Win program. Results: There were significant decreases in the lip paralysis status pain and in anxiety between pre and post Doin Gigong Exercise. Conclusion: The results indicate that Doin Gigong Exercise is effective for patients with Bell's palsy to decrease lip paralysis, pain and anxiety and therefore, an effective intervention for use with patients with Bell's palsy.

In the present work, vibration analysis of high speed rotary bell cup model for paint atomizer application is carried out through numerical simulation. At first, eight bell cup models, considering four different cup shapes and two different cup diameters, are proposed and corresponding dynamic characteristics are investigated. To evaluate the operating stability, critical speed analysis is conducted using Campbell diagram and separation margin between operating speed and critical speed is identified. Unbalance vibration responses are also studied according to operating speed and balancing quality grade of G. Finally, the stability and adequacy of the proposed bell cup models are discussed for field application.

The current trend in automotive finishing industry is to use more electrostatic rotating bell (ESRB) need space to their higher transfer efficiency. The flow physics related with the transfer efficiency is strongly influenced by operating parameters. In order to improve their high transfer efficiency without compromising the coating quality, a better understanding is necessary to the ESRB application of metallic basecoat painting for the automobile exterior. This paper presents the results from experimental investigation of the ESRB spray to apply water-borne painting. The visualization, the droplet size, and velocity measurements of the spray flow were conducted under the operating conditions such as liquid flow rate, shaping airflow rate, bell rotational speed, and electrostatic voltage setting. The optical techniques used in here were a microscopic and light sheet visualization by a copper vapor laser, and a phase Doppler particle analyzer (PDPA) system. Water was used as paint surrogate for simplicity. The results show that the bell rotating speed is the most important influencing parameter for atomization processes. Liquid flow rate and shaping airflow rate significantly influence the spray structure. Based on the microscopic visualization, the atomization process occurs in ligament breakup mode, which is one of three atomization modes in rotating atomizer. In the spray transport zone, droplets tend to distribute according to size with the larger drops on the outer periphery of spray. In addition, the results of present study provide detailed information on the paint spray structure and transfer processes.

In August 2006, a severe disease incidence showing mosaic and/or necrotic symptoms on two bell pepper varieties including red-colored 'Special' and yellow-colored 'Fiesta' was observed in a greenhouse located in Gwangyang, Jeonnam province, Korea. To identify causal viruses, total RNAs were extracted from 11 fruit samples with and without symptoms. Specific oligonucleotide primers for Cucumber mosaic virus (CMV), Pepper mottle virus (PepMoV), Tomato spotted wilt virus (TSWV) and Pepper mild mottle virus (PMMoV) were designed based on the sequences available on GenBank. Database comparisons of the deduced amino acid sequences of each sequence produced 100% and 98% matches with nucleocapsid protein gene of TSWV (Acc. No. ABE11605) and coat protein gene of CMV (Acc. No. DQ018289), respectively, suggesting that the symptoms on bell pepper fruits might be caused by the infection of CMV and TSWV. To our knowledge this is the first report of necrotic as well as mosaic virus disease on bell pepper fruits by the infection of CMV and TSWV in Jeonnam province, Korea.

서기 771년(신라, 혜공왕 7년)에 주조된 성덕 대왕 신종은 지면으로부터 약 50cm 떨어지게 설치되어 있으며 지면에 울림통을 가지고 있다. 이 울림통은 일종의 공명기의 역할을 하여 종 내부와 함께 성덕 대왕 신종의 고유한 소리 특성에 영향을 줄 것이라 예측되어 왔다.[1, 2, 3]. 본 논문에서는 이를 규명하기 위한 내부 음장의 3차원 측정 실험을 소개하고 있으며 울림통이 종소리에 끼치는 영향을 단순하나 물리적 현상을 대표하는 모델을 이용하여 설명하고 있다. 이러한 해석 방법을 기초로 하여 새로운 울림통의 크기를 제안하고 있다.
