한호성,엄지영,채희원 한국무역연구원 2023 무역연구 Vol.19 No.3
Purpose – After breaking the three-year hiatus in medical tourism due to COVID-19, the medical tourism industry is looking forward to reopening. This study conducted an empirical study on the importance and performance of medical tourism service quality to provide implications in accelerating the revitalization of the medical tourism industry. Design/Methodology/Approach – Existing studies related to the service quality of medical tourism have been conducted mainly targeting foreign patients. In order to balance this point of view, 50 medical tourism employees in Bucheon city were set as targets. Then, IPA analysis on medical tourism service quality was conducted. Findings – The medical infrastructure and system, intensive service for foreign patients only, and professional manpower have excellent service quality, and areas to be improved are the foreign patient telemedicine system of the medical system and the foreign language homepage of the service system. In order to revitalize medical tourism, it is necessary to consider priorities in the relevant areas. Research Implications – This study is meaningful as data for comparison with previous studies on medical tourism service quality before COVID-19. In addition, research on service quality for medical tourism employees was conducted to balance the implications of medical tourism research.

Supercapacitors have attracted great attention by many researchers as next generation energy storage devices. Among them, many researches have been conducted on conducting polymer-based supercapacitors due to their unique advantages such as fast and reversible redox reaction and high specific capacitance. However, in order to apply the conducting polymer to the electrodes for the supercapacitor, it is necessary to overcome the low reliability of the conducting polymer due to the low mechanical strength and short life cycle. Therefore, in this study, nanomaterial composite electrodes based on conducting polymers, which can realize higher storage capacity and excellent cycle stability through the introduction of various materials, were prepared. These materials were applied to two-electrode symmetric and asymmetric supercapacitors, and the electrical and electrochemical properties of the fabricated devices were compared and analyzed.

한호성,조성훈 한국공업화학회 2017 한국공업화학회 연구논문 초록집 Vol.2017 No.1
Polypyrrole (PPy) and Silica (Si) were successfully formed as a nanostructured core-shell. In this work, the synthesized PPy/Si core-shells were used as symmetric electrodes for two-electrode supercapacitor. The morphology and structural properties of samples were determined by scanning electron microscopy (SEM), transmission electron microscopy (TEM) and fourier-transform infrared (FT-IR) spectroscopy. The electrochemical properties of sample have been investigated using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS) and galvanostatic charge-discharge test. The results of this paper have shown that the supercapacitor using PPy/Si core-shell as symmetric electrodes has mass capacitance of 69.020 F/g and power density of 300.08 W/kg through electrochemical analyses.

This work describes solid-state asymmetric supercapacitors (ASCs), composed of aniline oligomers as a cathode, reduced graphene sheet as an anode and sealed with solid electrolyte. This research clarifies the synergetic effects on electrical and electrochemical performances resulting from of combination between aniline oligomers and waterdispersible graphene (WDG) sheet. The electrical and electrochemical properties of ASCs were highly dependent on the protonation levels of aniline oligomers including aniline tetramer, aniline trimer, and aniline dimer. The aniline tetramer with an appropriate chain length provided sufficient carrier transport within the cathode compared to the other oligomers. The ASC composed of aniline tetramer/WDG exhibited high areal capacitance (62.2 mF/cm2), volumetric capacitance (207.4 F/cm3), and good cycling stability (97.2% after 2000 cycles and 90.4% after 10000 cycles).
