패밀리 레스토랑 일선 직원의 고객언어폭력, 감정고갈 및 생활만족 간의 구조적 관계에서 임파워먼트의 완충역할

김태구,이계희 한국외식경영학회 2012 외식경영연구 Vol.15 No.6

This study investigates the structural relationships of customer verbal aggression (CVA; job stressor), emotional exhaustion (EE; psychological job strain), and life satisfaction (LS), with empowerment (EMP; job resource; coping resource) serving as a moderator in the CVA-EE relationship as well as the CVA-LS relationship, using data collected from a survey of 266 family restaurant frontline employees in Seoul. This study used a structural equation modeling to investigate the research model and hypotheses. CVA increased EE and EE decreased LS. The results indicate that CVA positively and significantly influences EE, and EE negatively and significantly influences LS. However, CVA showed a negative but not significant relationship with LS. Our study findings further demonstrated that the positive amplifying effect of CVA on EE was weaker for employees with high EMP as opposed to that with low EMP. However, EMP did not show a buffering role between CVA and LS. The study concludes with a discussion of the empirical findings, managerial implications, and theoretical contributions. 환대 및 서비스 기업의 일선 직원들은 “고객은 항상 옮다” 혹은 “고객은 왕이다”와 같은 기업의 경영철학에 따라 친절하고 예의 바른 태도를 통하여 항상 웃는 얼굴로 고객을 응대해야 하므로 심리적으로 상당한 스트레스를 받고 이는 그들의 전반적인 조직생활뿐만 아니라 일상생활에 이르기까지 광범위하게 상당한 부정적인영향을 미친다. 본 연구의 목적은 패밀리 레스토랑 일선 직원의 고객언어폭력(직무 스트레스 요인), 감정고갈(심리적 직무긴장) 및 생활만족 간의 구조관계에서임파워먼트(직무 스트레스 대처자원)의 완충역할을 실증적으로 규명하는 것이다. 본 연구에서는 동일방법편의로 인한 변수들 간의 관계왜곡을 최소화하기 위하여독립변수와 종속변수 조사에 있어서 1개원 간의 시차를 두고 두 시점에서 각각 다르게 구성된 두 개의 설문지를 통해서 조사를 하였다. 서울에 소재하는 5개의 체인 패밀리 레스토랑 25개 지점에 근무하는 266명의 일선 서비스 직원들로부터 수집된 자료를 최종 분석에 적용하였다. 연구모형을 평가하고 연구가설들을 검증하기 위하여 구조방정식 모형분석을 적용하였다. 실증분석 결과, 고객언어폭력은 감정고갈을 증대시키는 것으로 나타났다. 또한, 감정고갈은 생활만족을 감소시키는것으로 나타났다. 하지만 고객언어폭력으로 인하여 생활만족은 감소하지 않는 것으로 도출되었다. 즉, 감정고갈은 일상생활에 대한 만족에 부정적인 전이 효과가있지만, 고객언어폭력은 일상생활에 대한 만족에 부정적인 전이 효과가 없다는 것을 알 수 있었다. 특히, 본 연구에서는 고객언어폭력이 생활만족을 경감시키는데있어서 임파워먼트가 완충역할을 하지 않는 반면에, 고객언어폭력이 감정고갈을증대시키는데 있어서는 임파워먼트가 완충역할을 하는 것으로 규명되었다.

천공성 충수염에서 복강경 충수 절제술의 유용성

김태구,정기훈,정호근 대한내시경복강경외과학회 2011 Journal of Minimally Invasive Surgery Vol.14 No.2

Purpose: Laparoscopic appendectomy (LA) is currently more popular than an open appendectomy (OA), because of its advantages, such as a decrease in postoperative pain, short hospitalization and quick recovery. On the other hand, the efficacy and safety of a laparoscopic appendectomy for complicated appendicitis is controversial. Therefore, this study compared the efficacy and safety of LA and OA. Methods: This study reviewed retrospectively 262 patients with perforated appendicitis who underwent ether open or laparoscoic appendectomy between January 2001 and December 2010. The medical record and video were used to collect data. The operative time, length of hospital stay, time to diet, time to remove drain and complications were assessed. Results: There were 207 and 55 patients in the OA and LA group, respectively. The operation times were significantly longer in the LA group than the OA group (OA group 68.25±33.08 vs. LA group 90.80±47.64 min) (p<0.05). The length of hospital stay was longer in the OA group than the LA group (OA group 10.96±5.24 vs. LA group 8.86±5.18 days) (p<0.05). The time to diet and time to remove the drain was longer in the OA group than the LA group (p<0.05). The postoperative complication rate was similar in the two groups. Conclusion: The operative time was longer in the LA group but the length of hospital stay, time to diet, and time to remove drain was longer in the OA group. Such merits show that laparoscopic appendectomy is a good surgical option for perforated appendicitis.

This study was carried out to investigate the effects of different plant helght on the total water soluble carbohydrate in the leaf, stem, and root of orchardgrass (Dactylis glomerota), perennial ryegrass (Lolium perenne) and red top (Agrosfis alba), grasses of temperate origin grown in experimental plots at Cheju National University, from September, 1984 to September, 1985. The results obtaind were as follows; 1. The dry matter produrtlvity of orchardgrass was 1,449kg/10a, of perennial ryegrass, 757kg/10a and of red top, 531kg 10a. The dry matter yield of orchardgrass was higher than the other grasses and when compared with the others was statistically highly significant(P<0.01) 2. The total dry matter yield varled according to plant height cutting. There were highly significant differences between grasses 20cm and 30cm or 40cm tall. However, there were no statistically significant differences between grasses 30cm and 40cm in height. 3. During the hot season, when grasses were cut for the third time. the total water soluble carbohydrate decreased in orchardgrass and perennial ryegrass but increased in red top. 4. Except for a slightly Increased total water soluble Carbohydrate in all parts of grasses at 2Ocm tall, there were no differences in carbohydrate content at other helghts. 5. The dry matter yield of orchardgrass and perennlal ryegrass at 2Ocm rose as the total water soluble carbohydrate increased but decreased in red top at all plant height. Statlstically, there was no significant correlation between total water soluble carbohydrate and dry matter yield of grasses.

Overnight Index Swap을 이용한 원화 무위험금리 추정 및 분석

Since the global financial crisis, CCP-cleared and global margin trades have been increasing in overseas swap markets, leading to the stage that swap pricing convention has been in transition from single curve to dual curve method. Along with this trend, collateralized swap trades in Korea grow under both CCP clearing and global margin regulations, however the pricing by dual curve has yet to be developed. As to collateralized swap, the pricing by single curve will result in mis-pricing because future cash flows are to be derived from swap rate curves and discounting factor calculated from the same curves. This study investigates a solution to sort out mis-pricing, using a discounting curve that has been estimated aside from swap rate curve based on Hull-White one factor model, where the model is tested against IRS and OIS rates across USD, GBP and AUD swap markets. As a result from the repricing of collateralized KRW-IRS, swap prices by dual curve are observed consistently higher than that by single curve for the received position at the KRW-IRS rates rally, and higher than that by single curve for the paid position at the KRW-IRS rates sell-off. Conclusively when CCP-cleared and Global Margin trades are discounted using single curve, prices are under or over-valued, allowing economic wealth to be transferred without a proper cost. To address these issues on collateralized swap pricing, the KRW-OIS market should be established and swap pricing convention by KRW-OIS rates needs to be settled down at the earliest date. 글로벌 금융위기 이후 해외의 선진 스왑시장은 CCP(Central Counterparty) 청산과 증거금(Global Margin) 거래가 확대되면서 스왑 평가의 관행이 기존의 single curve 방식에서 dual curve 방식으로 전환되고 있다. 이러한 추세에 발맞춰 국내에서도 CCP 청산과 Global Margin 제도가 도입되었고 관련 거래가 지속적으로 증가하고 있으나 아직은 dual curve를 이용한 스왑 평가가 정착되지 못한 실정이다. 담보부 스왑 거래와 관련하여 single curve에 의한 평가는 미래 현금흐름과 할인계수가 동일한 수익률 곡선에서 유도됨에 따라 평가 오류가 발생한다. 본고에서는 dual curve 방식을 적용하여 현금흐름을 발생시키는 수익률 곡선과는 별개로 할인계수에 사용되는 수익률 곡선을 추정함으로써 해법을 제시하고자 한다. 이를 위해 Hull-White One Factor 모형을 기반으로, 해외 OIS(Overnight Index Swap) 시장에서 유동성이 뛰어나고 장기물이 거래되고 있는 USD, GBP, AUD 스왑시장의 자료를 이용하여 원화 담보부 스왑 거래의 할인에 사용되는 KRW-OIS금리를 추정하였다. 실증분석 결과 single curve 대비 dual curve에 의한 평가가 금리 하락기에는 고정금리 수취 포지션이, 상승기에는 고정금리 지급 포지션이 체계적으로 높게 평가되는 것으로 나타났다. Single curve를 사용하여 CCP 청산 및 Global Margin 거래를 평가할 경우 특정 포지션이 과대 또는 과소평가되는 현상이 발생하고 거래 당사자 간에 일방적인 이익 이전이 발생하는 문제가 확인되었다. 이를 해소하기 위해서는 KRW-OIS시장이 조성되고 KRW-OIS금리에 의한 스왑 평가가 정착될 필요가 있다.

Based on data collected from ten five-star hotel frontline employees in Busan, we developed and tested a model investigating the structural relationships among empowerment (job resource), customer verbal aggression (job stressor), and emotional exhaustion (job strain). We also incorporated customer orientation (personal coping resource) into the model and tested its moderating role. This study used structural equation modeling to investigate the research model and hypotheses. As hypothesized, empowerment decreased customer verbal aggression and emotional exhaustion. The results revealed that customer verbal aggression intensified emotional exhaustion. Our findings further demonstrated that the positive amplifying effect of customer verbal aggression on emotional exhaustion was weaker for employees with high customer orientation as opposed to that with low customer orientation. The study concludes with a discussion of the empirical findings, theoretical contributions and managerial implications.
