Objectives : The purpose of this study is to report a case of bilateral facial palsy in a patient with Guillain-Barre Syndrome after coronavirus disease 2019(COVID-19) vaccination. Methods : The patient diagnosed as Guillain-Barre Syndrome and Bilateral facial palsy after COVID-19 vaccination. We applied Korean medical treatment including acupuncture and herbal medicine for bilateral facial palsy. We used HBGS(House-Brackmann Grading System), VAS(Visual Analog Scale) to estimate the symptoms. Results : After the treatment, both facial palsy showed big improvement. Compared to the onset, HBGS improved by Grade 1/2 and VAS by 2. Conclusions : This case report shows effect of Korean medicine on Bilateral facial palsy and suggests a possibility of Korean medicine to treat adverse events following COVID-19 vaccination.

Bilateral pectoralis major myocutaneous (PMMC) flaps are commonly used to reconstruct large chest wall defects. We report a case of large chest wall defect reconstruction using bilateral PMMC flaps augmented with axillary V-Y advancement rotation flaps for additional flap advancement. A 74-year-old male patient was operated on for recurrent glottic squamous cell carcinoma. Excision of the tumor resulted in a 10×10 cm defect in the anterior chest wall. Bilateral PMMC flaps were raised to cover the chest wall defect. For further flap advancement, V-Y rotation advancement flaps from both axillae were added to allow complete closure. All flaps survived completely, and postoperative shoulder abduction was not limited (100° on the right side and 92° on the left). Age-related skin redundancy in the axillae enabled the use of V-Y rotation advancement flaps without limitation of shoulder motion. Bilateral PMMC advancement flaps and the additional use of V-Y rotation advancement flaps from both axillae may be a useful reconstructive option for very large chest wall defects in older patients.

Although there is growing literature evidence of linkages between global value chains (GVCs) and foreign direct investment (FDI), the results are mixed and ambiguous by geographic dimension, time period and sectoral scope. Moreover, bilateral approaches on these connections have been rarely analyzed. In this context, we investigate the effect of bilateral greenfield FDI and cross-border M&A on GVC linkages between host countries and source countries. We match three-year averages of bilateral FDI and UNCTAD-Eora GVC value-added data from 2005 to 2019 between 37 OECD sources and 176 host countries (37 OECD versus 139 non-OECD countries). In the structural gravity model, the empirical specification includes bilateral and country-period fixed effects and uses a Poisson Pseudo-Maximum Likelihood (PPML) estimator. We find that greenfield and M&A FDI promote forward and backward GVC linkage for all sectors between OECD countries, whereas greenfield FDI promotes backward GVC linkage between OECD and non-OECD countries. In addition, the results indicate that the degree of influence of GVCs by FDI flows is greater for forward GVC than backward GVC among OECD countries.

Objective: To describe the HRCT findings of cytomegalovirus (CMV) pneumonia in non-AIDS immunocompromised patients Materials and Methods: This retrospective study involved the ten all non-AIDS immunocompromised patients with biopsy-proven CMV pneumonia and without other pulmonary infection encountered at our Medical Center between January 1997 and May 1999. HRCT scans were retrospectively analysed by two chest radiologists and decisions regarding the findings were reached by consensus. Results: The most frequent CT pattern was ground-glass opacity, seen in all patients, with bilateral patchy (n = 8) and diffuse (n = 2) distribution. Other findings included poorly-defined small nodules (n = 9) and consolidation (n = 7). There was no zonal predominance. The small nodules, bilateral in eight cases and unilateral in one, were all located in the centrilobular region. Consolidation (n = 7), with patchy distribution, was bilateral in five of seven patients (71%). Pleural effusion and bilateral areas of thickened interlobular septa were seen in six patients (60%). Conclusion: CMV pneumonia in non-AIDS immunocompromised patients appears on HRCT scans as bilateral mixed areas of ground-glass opacity, poorly-defined centrilobular small nodules, and consolidation. Interlobular septal thickening and pleural effusion are frequently associated.

Objectives : The purpose of this study is to report on the good results achieved through Korean and western medicine treatment on patients with idiopathic bilateral facial nerve palsy. Methods : We treated a female patient with idiopathic bilateral facial nerve palsy by Korean medicine treatment such as herbal medicine, acupuncture, pharmacopuncture, cupping therapy, and taping therapy. The patient also received western medicine treatment. The treatment effect was evaluated by visual observation through photography, House-Brackmann scale, Yanagihara's scale, standardization of muscular paralysis, and clinical symptoms. Results : After the treatment, muscle movements and clinical symptoms improved, and all facial palsy evaluation indicators also showed improvement. In particular, the House-Brackmann-scale showed improvement from (3/4) to (1/2). Conclusions : This case study shows that Korean-western medicine combination treatment for idiopathic bilateral facial nerve palsy can be effective. We hope that case reports and clinical research will continue to be actively conducted in the future.

We herein present the unique case of a 68-year-old male diabetic patient who developed sterile necrosis of the sternum 1 month after myocardial revascularization with the use of bilateral internal thoracic artery grafts. The sternum had been closed by the bilateral Robicsek wiring technique. The sternum was removed, and bilateral pectoralis major flaps were used to cover the defect. The patient had an uneventful recovery.

The spontaneous bilateral asymmetry was analyzed in the hermaphroditic fish Rivulus marmoratus to obtain base line data on the developmental stability of this fish. The results obtained were as follows; 1. Eight kinds of countable anatomical characters except numbers of otolith and radii branchiostegi showed bilateral asymmetry at the frequency ranging from 9.8% to 64.7%. 2. Asymmetry index was not significantly different from that of gonochoristic fish species previously reported. Genetical implication of the results was discussed in relation to developmental stability and homozygosity of this species.

In the present paper, we consider an anomalous diffusion problem in two dimensional space involving Caputo time and Riesz-Feller fractional derivatives and then solve it by using a series involving bilateral eigen-functions. Also, we obtain a numerical approximation formula of this problem and discuss some of its particular cases.

The objective of this paper is to design a force feedback controller for bilateral control of a master-slave manipulator system. In a bilateral control system, the motion of the master device is followed by the slave one, while the force applied to the slave is reflected on the master. In this paper, a fuzzy logic controllers applied to the system. Using the fuzzy logic controller, the knowledge of the system dynamics is not needed. Simulations and experimental results show the performance of the proposed controller.

Basic types of bilateral servo systems were described and practical consideration in the bilateral servo controller design was introduced. Power assistance to the operator is essential for high efficiency and accurate force reflection is necessary for dexterous manipulation. This paper shows a controller structure under development at KIMM which employs nonlinear friction compensation and memory based gravity compensation technique for efficiency and dexterity.
