Treatments of choice for cardiac implantable electronic device (CIED) infections are the removal of the entire CIED system, control of infection, and new device implantation. Occasionally, a complete CIED removal can not be performed for several reasons, such as very old age, severe comobidity, limited life expectancy, or refusal by a patient. We encountered a male patient who developed traumatic CIED infection five years after cardioverter-defibrillator implantation. An intravenous electrode could not be removed by a simple transvenous extraction procedure, and he refused surgical removal of the remnant electrode. After control of local infection, the tips of the electrode were separated and buried between muscles, and the wound was closed with a local flap. CIED infection did not recur for 12 months even without relying on long-term antimicrobial treatment.
여행사의 조직공정성이 종사원의 심리적 자본과 조직시민행동에 미치는 영향 연구
한성환 관광경영학회 2018 관광경영연구 Vol.84 No.-
The change of value on travel has brought about dramatical increase of the number of tourists due to rising incomes and leisure time. Despite the growth of the travel industry, the job satisfaction level of those who work in the travel industry is low. To solve this problem, it is important to highlight the workers' value by recognizing them as internal customers instead of conventional means like physical capital. The travel industry is a service industry that highly relies on human resources, so individual management of workers is critical. As many studies show, human resources are a strategical element and core asset for the competitive advantage and development of company. The workers' organization citizen's action, which is not official but spontaneous behaviors, can have an important effect on customer satisfaction and choice of travel agency. To draw workers' organization citizen's action, there should be the change of workers' psychological capital according to organizational justice. For actual proof analysys, i have extracted 300 samples through a survey performed on employee of travel agency’s, and analyzes basic data and structural equation model by using SPSS and AMOS. Thus, this study is intended to emphasize the importance of internal customers in the management of tour companies and to provide practical implications by verifying the influencing relationship among organizational justice that workers recognize, their psychological capital and organization citizen's action.
여행사의 내부마케팅 요인이종사원의 자기효능감과 조직몰입에 미치는 영향 연구

By carrying out the empirical analysis targeting travel agency employees based on the theoretical review of internal marketing factors affecting travel agency employees and the effect of higher self-efficacy of employees on organizational commitment, this paper was to study with which internal marketing factors travel agencies can increase the self-efficacy of employees and improve their organizational commitment Based on these results, by increasing the self-efficacy of employees through the strengthening of communication, empowerment, fair evaluation and compensation rather than strengthening management policy, education and training, travel agencies should provide efficient and rational internal marketing so that employees can have high organizational commitment by highly evaluating themselves and feeling the contentment in the psychological part.
Self-Assembled Multilayers of Donor-Sensitizer-Acceptor System for Solar Cell
한성환 한국공업화학회 2002 한국공업화학회 연구논문 초록집 Vol.2002 No.0
Construction of molecular acrchitecture were performed to give photovoltaic effects. A dense self-assembled monolayer of 1, 3-diaminopropylviologen was formed on the ITO surface. The amine group in 1,3-diaminopropylviologen was found to have good affinity for the ITO material The diamine functionality of 1,3-diaminopropylviologen was utilized for the preparation of another layer of Ru-Sensitizer to form Acceptor―Sensitizer system on ITO surface. Self―Assembled multilayers on the ITO surface showed good photovoltaic performance in the presence of iodine containing electrolyte.

본 연구에서는 석유화학공정에서 잠재위험요소를 확인하고, 사고 결과분석을 통해 안전대책 수립 등의 위험관리 방안을 제시하고자 하였다. 이를 위해 프로필렌 회수공정(PRP)에서 현실적인 상황을 고려한 누출 시나리오를 선정하고, PHAST RISK(ver. 6.7) 프로그램을 사용하여 화재 및 폭발 사고의 피해범위를 산출하고, 피해영향을 해석하였다. 그 결과, 6개의 PRP 공정지역 중에서 디프로파나이저 지역, 디에타나이저 지역 및 히트펌프 지역에서는 화재 및 폭발 사고의 피해범위가 매우 크게 나타났다. 따라서 제트화재가 발생하는 공정지역에서는 200 m의 반경 내에서 사람이 상주할 수 있는 건물을 설치하지 않는 것이 바람직하고, 재고량과 압력이 큰 공정지역에서는 사고위험을 사전에 예방해야 하고, 사고 발생 시에는 신속한 대처방안 수립이 요구되었다. This study aims to suggest risk management plan including safety measures through hazard identification followed by consequence analysis in petrochemical plants. Consequence analysis was performed through practical release scenario by using PHAST RISK(ver. 6.7) software in the propylene recovery process(PRP). As results, consequences by fire or explosion accidents in the depropanizer zone, deethanizer zone and heat pump zone were relatively larger than other else zones among six process zones in the PRP. In the case of jet fire, it is recommendable not to install residence building within 200 m of the process zone. Additionally, process zones having large inventory or high pressure must be prevented from accidents and required to establish quick response against accidents.
