Nowadays, the importance of respiratory therapy is increasing with the development of modern medicine. Especially effective roupiratory care in the field of anesthesia and intensive care unit has close releatinship to the decrease of mortality or morbidity of the critically ill patients. Compared with spontaneous respiration, so various phusiological changes related to these methods can occur. Because most modernized ventilations can choose the various respiratory pattens according to the patients' respiratory condition, it is ideal to select the respiratory mode which is least hazardous and most effective to the patients. To confirm the effects of respiratory therapy on the cardiovascular system and arterial blood gas in one-lung ventilation and in pulmonary edema, we made one-lung ventilation by deep right endobronchial intubation and pulmonary edema was induced by oleic acid (0.05g/kg. IV) to 12 mongrel dogs. And we ovserved the cardiovascular changes and arterial blood gas analysis in the situation of applying the inspiratory pause (0.25 sec. and 0.5 sec) and positive end-expiratory pressure (5 cm H_2O and 10 cm H_2O). The results were as follows: 1) One-Lung Ventilation (1) Insipratory pause There were no changes of cardiovascular system and arterial blood gas in the inspiratory pause of 0.25 and 0.5 sec. (2) PEEP In 5 cmH_2O of PEEP there was no change of cardiovascular system, but there was decrease in PCO_2(P<0.01) on arterial blood gas. In 10 cmH_2O of PEEP there was increase in heart rate(P<0.05) and decrease in cardiac output(P<0.05). THere was decrease in PCO_2(P<0.01), but there were no changes of pH and PO_2 on arterial blood gas. 2) Pulmonary Edema (1) Inspiratory pause There was increase in heart rate(P<0.01), but there was no change of arterial blood gas in the 0.25 and 0.5 sec. inspiratory pause. (2) PEEp In 5 cmH_2O of PEEP there was incrase in heart rate(P<0.01), but there was no change of arterial blood gas in the 0.25 and 0.5 sec. inspiratory pause. In 10 cmH_2O of PEEP there decreas in sBP,dBP,MAP,increase in heart rate(P<0.05) and decrease in cardiac output(P<0.01). There were increase in pH(P<0.05) and PO_2(P<0.01), decrease in PCO_2. According to the above results in the condition of one-lung ventilation mechanical ventilation with inspiratory pause (0.25 or 0.5 sec.) was not helpfur to respirrotry care. 5 cmH_2O PEEP could improve the pulmonary ventilation without ay changes of cardiovascular system, but 10 cm H_2O PEEP increased heart rate and decrease cardiac output. In the condition of pulmonary edema, mechanical ventilation with inspiratory pause (0.25 or 0.5 sec.) could not improve the pulmonary ventilation with depression of cardiovascular system. PEEP (55 or 10 cmH_2O) could improve the pulmonary condition in proportion to PEEP, but it also depressed the cardiovascular system. Therefore we concluded that mild degree PEEP(5 cmH_2O) may be helpfurl to the one-lung ventilation or pulmonary edema.

The lodgement of foreign material in the larynx is potentially life thereatening as complete obstruction of this region does not leave the individual with a viable airway. In the literature review, laryngeal foreign bodies accounted for about $3\%$ of the whole foreign bodies in the air passage. This report describes a rare case of laryngeal obstruction by subglottic foreign body(tooth) occurred during tooth extraction, in which repeated Heimlich maneuver failed to expel the foreign body and aggravated airway obstruction.

상사의 비인격적 감독과 부하의 업무노력 및 상사대상 일탈행동의 관계에 대한 연구: 상사-부하간 꽌시의 조절효과를 중심으로

최병권,이영 리더십학회 2020 리더십연구 Vol.11 No.3

This study aims to verify the curvilinear relationships between abusive supervision and subordinates' work effort (U-shaped) and supervisor-directed deviant behavior (Inverted U-shaped) and to examine the moderating effect of supervisor-subordinate guanxi. Using self-reported data from 260 Chinese employees, we found supports for a U-shaped relationship between abusive supervision and work effort and an inverted U-shaped relationship between abusive relationship and supervisor-directed deviant behavior. Regarding moderating role of guanxi, while an U-shaped relationship between abusive supervision and work effort was significant for subordinates perceiving high level of guanxi, abusive supervision has a linear and negative relationship with work effort for subordinates perceiving low level of guanxi. Meanwhile, whereas an inverted U-shaped relationship between abusive supervision and supervisor-directed deviant behavior was signigicant for subordinates with high levels of guanxi, such curvilinear relationship was also valid for those with low levels of guanxi. We discussed the implications, limitations, and agenda for future research. Key words: Abusive supervision, Work effort, Supervisor-directed deviant behavior, Supervisor-subordinate guanxi 본 연구는 상사의 비인격적 감독과 부하의 업무노력 및 상사대상 일탈행동 간의 비선형 관계, 그리고 이러한 비선형 관계에서 상사-부하간 꽌시(Supervisor-Subordinate Guanxi)의 조절효과를 살펴보고자 시행되었다. 설문조사를 통해 수집한 260명의 중국 직장인 자료를 위계적 다항회귀분석을 통해 분석한 결과, 비인격적 감독은 업무노력과는 U자형 관계를, 일탈행동과는 역U 자형 관계를 갖는 것으로 나타났다. 상사-부하간 꽌시의 조절효과의 경우, 높은 수준의 꽌시를 인식하는 부하에게서는 비인격적 감독과 업무노력 간의 U자형의 비선형 관계가 유의했으나, 낮은수준의 꽌시를 인식하는 부하에게서는 비인격적 감독과 업무노력 간 부(-)의 선형관계가 나타났다. 한편, 비인격적 감독과 일탈행동 간의 역U자형의 비선형 관계는 꽌시 수준에 관계없이 유의하였으나, 꽌시를 높게 인식하는 부하에게서 상대적으로 더 강하게 나타났다. 이상의 결과를 토대로 본 연구결과의 시사점을 논의하였으며, 본 연구의 한계 및 향후 연구방향을 제시하였다. 키워드: 비인격적 감독, 업무노력, 상사대상 일탈행동, 상사-부하간 꽌시

비인격적 감독 분야의 선행연구들은 상사의 비인격적 감독이 부하의 정서적 소진에 부정적 영향을 미친다고보고하고 있으나, 비인격적 감독이 어떠한 내적 프로세스를 통해 정서적 소진을 촉진하며, 또한 언제 이러한관계가 강화 또는 약화될 수 있는가에 대한 연구는 미흡하였다. 본 연구에서는 상사와 부하 간의 사회적 교환관계를 기반으로 업무 측면의 교환관계인 상사-부하 교환관계(leader-member exchange; LMX)와 비업무 측면의개인적 교환관계인 상사-부하 꽌시(guanxi)의 서로 다른 특징을 지닌 두 유형의 상사-부하 간 관계의 역할에주목하였다. LMX와 꽌시를 활용하여, 본 연구는 비인격적 감독과 정서적 소진의 관계에서 LMX의 매개효과와꽌시의 조절효과, 그리고 LMX의 매개효과가 꽌시의 수준에 의해 다르게 발현되는 조절된 매개효과를 검증하였다. 287명의 중국 직장인을 표본으로 설문조사를 통해 확보한 자료를 분석한 결과, 상사의 비인격적 감독은부하의 정서적 소진에 정(+)의 영향을 미치는 것으로 나타났으며, LMX는 상사의 비인격적 감독과 부하의정서적 소진의 관계를 매개하는 것으로 나타났다. 또한 꽌시는 상사의 비인격적 감독과 LMX의 관계를 조절하는 것으로 나타났으며, LMX를 매개로 하는 비인격적 감독의 정서적 소진에 대한 간접효과는 꽌시의 수준에따라 다른 것으로 나타났다. 즉, 비인격적 감독이 LMX를 매개로 정서적 소진에 미치는 간접효과는 꽌시를낮게 인식하는 부하에서는 유의하지 않은 반면, 꽌시를 높게 인식하는 부하에게서 유의하게 나타났다. 본 연구의 이론 및 실무 측면의 시사점을 논의하고, 연구의 한계점 및 향후 연구방향을 제시하였다. Although previous research have revealed the negative impact of supervisors' abusive supervision on subordinates' emotional exhaustion, yet little research to date has investigated which variables explain why abusive supervision leads to emotional exhaustion and when such relationship may be stronger or weaker. Based on social exchange theory, we focused the roles of two distinct types of supervisor-subordinate exchange relationships: LMX(leader-member exchange) based on work-related relationship and supervisor-subordinate Guanxi based on nonwork-related personal relationship. By integrating LMX and guanxi, we proposed and tested a moderated mediation model that includes LMX as the mediator and guanxi as the moderator in relationship between abusive supervision and emotional exhaustion. Results based on 287 Chinese employees provided support for our hypotheses. We found that abusive supervision was positively related to emotional exhaustion and LMX mediated such relationship. We found further that guanxi moderated the relationship between abusive supervision and LMX; revealing that the negative influence of abusive supervision on LMX was stronger when subordinates perceived a high level of guanxi. Finally, a moderated mediation analyses showed that the mediated relationship between abusive supervision and emotional exhaustion through LMX was different on the moderator variable of guanxi. Specifically, the conditional indirect effect of abusive supervision on emotional exhaustion through LMX was valid under high level of guanxi, not under low level of guanxi. Implications for research and practice were discussed along with study limitations and future research directions.
