해외파견자의 다면적 현지적응에 대한 실증연구

박용석(Yong Suhk Pak),장기홍(Ki Hong Jang) 연세대학교 경영연구소 2008 연세경영연구 Vol.45 No.1

본 연구는 이문화 환경에서 해외파견자의 효과적인 현지적응에 대하여 실증적으로 검증하였다. 다국적기업에 있어 국제적 경영활동을 통한 핵심역량 획득에 있어 해외파견자의 운용은 필수적 이지만, 해외파견자가 파견국에 효과적으로 적응하기 위해서는 많은 제한 요인들이 작용하게 된다. 이에 본 연구는 기존연구들에서 제시한 다면적 차원의 현지적응 형태에 개인, 조직 차원의 요인들을 추가한 인과관계 모형을 도출하여 검증하였다. 본 연구에서는 해외파견자의 개인역량요소의 자가유능감과 관계개선능력이 다면적 현지적응에 미치는 영향, 그리고 현지적응의 다면적 차원의 형태들 간의 관계에 대해 분석하였다. 군에서 해외로 파견한 81명의 해외파견자 (해외무관, 국외군사교육생)를 대상으로 획득한 설문을, PLS 구조방정식을 이용하여 분석한 결과 관계개선능력은 상호작용적응에 긍정적 영향을 미치는 것으로 나타났고, 자기유능감은 일반적응에 긍정적 영향을 미치는 것으로 나타났다. 또한, 사회적 지원은 상호작용적응 및 일반적응에 긍정적 영향을 미치며, 복지지원도 일반적응에 긍정적 영향을 미치는 것으로 나타났다. 현지적응의 다면적 형태들의 관계에 있어서는 상호작용적응과 일반적응, 상호작용적응과 직무적응, 일반적응과 직무적응 간에 긍정적 관계를 형성하고 있음이 나타났다. 이에 관한 의미는 본 연구의 토론부분에서 설명하고 있다. This study attempts to examine the relationship of expatriates’ multi-dimensional in-country adjustments (work adjustment, interaction adjustment, general adjustment). In the era of global competition, the role of expatriate has become increasingly important especially for multinational companies (MNC). However, adjusting to a different cultural context is a daily challenge for expatriates. The purpose of this study is to examine individual factors (relation skill and self-efficacy) and organizational factors (social support and logistic support) as predictors of multi-dimensional in-country adjustment of expatriates. This study also examines the relationship of expatriates ’ multi-dimensional in-country adjustments. The test results of questionnaire survey on 81 abroad military students and abroad military officers dispatched overseas by the military show that interaction adjustment was influenced by relation skill and general adjustment that was influenced by self-efficacy. Also, social support facilitates interaction adjustment and general adjustment, and logistic support facilitates general adjustment. In the multi-dimensional in-country adjustment context, interaction adjustment facilitates general adjustment, and work adjustment was influenced by both interaction adjustment and general adjustment. Further discussion on the findings was addressed at the end of the paper.

목적 : 재발성 난소암에서 platinum 감수성을 기준으로 2차 항암요법으로 사용한 Carboplatin과 Paclitaxel의 효과를 알아보기 위하여 본 연구를 진행하였다. 연구방법 : 1998년 1월 1일부터 2003년 8월 31일까지 만 5년 8개월 간 아주대학교병원 산부인과에 재발성 난소암으로 입원한 환자 중에서 최초 수술로 난소암을 확진한 후 Cisplatin 또는 Carboplatin 등 platinum 제재가 포함된 항암치료를 받은 후 6개월 이후에 재발한 환자 29명을 대상으로 Carboplatin은 5 AUC를 그리고 Paclitaxel은 175 mg/m^(2)를 투여하였으며, 최소 3회에서 최고 16회까지 투여하였다. 치료효과의 판정은 CT, MRI, Ultrasonography등 영상진단상 암종괴의 크기가 완전히 소실되었을 경우를 완전반응(complete response)으로, 50%이상 감소되었을 경우를 부분반응(partial response)으로, 50% 미만으로 감소되었거나 20% 미만 증가하였을 경우를 불변(stable disease)으로, 그리고 20% 이상 증가되었을 경우를 진행(progressive disease)로 정의하였다. 결과 : 대상 환자에서 완전반응은 6명(21%), 부분반응은 11명(38%), 그리고 불변은 5명(17%)로 전체 반응율 (overall response rate)은 59% 그리고 임상적 유용성(clinical benefit=CR+PR+SD)은 76%이었다. 결론 : 재발성 난소암환자에서 기왕에 사용한 Platinum 제재에 민감한 환자에서는 Carboplatin과 Paclitaxel의 병행 투여가 효과적이었다. Objective : To ascertain the effect of Carboplatin and Paclitaxel combination as a second line regimen for recurrent ovarian carcinoma based on platinum sensitivity. Methods : From January 1st, 1998 through to August 31st, 2003, 29 patients were retrospectively reviewed who had previously underwent primary cytoreductive surgery and adjuvant chemotherapy with Cisplatin or Carboplatin for ovarian carcinoma, and who had later recurred during follow up. All 29 patients had recurred at least 6 months after therapy, and thereafter received second line chemotherapy consisting of Carboplatin (5 AUC) and Paclitaxel (175 mg/㎡) for a minimum of least 3 cycles and a maximum of 16 cycles. Treatment efficacy was assessed by imaging studies including Computerized tomography, Magnetic Resonance Imaging, or Ultrasonography. Complete response was determined as complete disappearance of tumor, partial response at least than 50% reduction in tumor volume, stable disease as less than 50% reduction or less than 20% increase in tumor volume, and progressive disease as more than 20% increase. Results : There was complete response in 6 (21%) patients, partial response in 11 (38%), stable disease in 5 (17%), showing an overall response rate of 59%. The clinical benefit (CR+PR+SD) was 76%. Conclusion : The combination of Carboplatin and Paclitaxel administration seems to be an effective mode of second line therapy in patients with recurrent ovarian carcinoma who had been sensitive to prior platinum based chemotherapy.

재왕절개술을 위한 마취의 임상적 고찰

장기홍,서규석,임동원,진상호 대한마취과학회 1973 Korean Journal of Anesthesiology Vol.6 No.2

Anesthesia for cesarean section involves consideratian of Loth maternal and fetal welfare. The choice of anesthesia for cesarean section is controversial. Regional analgesic techniques may be least harmful to the fetus, but suffer definite drawbacks; they are time-consuming, and therefcre not always applicable when urgent surgery is indicated; are associated with a definite failure rate even in skilled hands, and require considerable technical ability and practice. Recently there has been progressive increase in the use of balanced anesthesia for cesarean section, it produces little or no hemodynamic and acid-base disturbance in the mother and infant if administered skillfully. The value of muscle relaxants to facilitate endotracheal intubation and pulmonary ventilation and to permit the use of light general anesthesia. From November, 1971 to October, 1973 there were 1,432 deliveries, of which 1,284 were delivered vaginally and 148 (10.3%) by cesarean section. Of the cesarean section group, 139 were performed under general anesthesia and 9 were performed under regional anesthesia. The characteristic difference for our series was that most of all cases were emergency cesarean section (71.6%). The major indication for surgery was that of a previous cesarean section (45.3%), the second most common cause was dystocia (42.9%), and the others are as following order; Hemorrhage (5.4%), toxemia (3.4%), and others (3.4%). In our study, we adopted two different general anesthetic techniques for cesarean section. Patients were randomly assigned to two groups: Group I: 112 patients, thiopental-succinylcholine-nitrous oxide-oxygen (67:33) anesthesia. Group II: 25 patients, thiopental-succinylcholine-nitrous oxide-oxygen (50:50) supplemented with 0.5~1.0% of halothane anesthesia. All patients were pre-oxygenated for 3 5 minutes and anesthesia was then induced with thiopental sodium 125~250mg, followed by succinylcholine 40~50 mg to facilitate intubation. Pressure was maintained on the cricoid cartilage to prevent regurgitation following loss of consciousness. After the affects of succinylcholine showed signs of wearing off, relaxation was maintained with 0.1% succinylcholine drip or 40~80 mg of gallamine. Anesthesia was maintained with nitrous oxide 4 l/min. and oxygen 2 l/min. and/or nitrous oxide 2 l/min. and oxygen 2 l/min. supplemented with 0.5~1.0% of halothane. Respiration was carefully controlled by manually so as not to producing hyperventilation. The clinical condition of newbron infant in general anesthesia series of 135 cases, mean minute apgar score were gcod (7~10) in 91.8 per cent, fair (4~6) in 6.7 per cent, and poor (1~3) in 1.5 per cent. And 90.4 per cent of babies born within 10 minutes of induction to delivery time interval (IDI) had mean apgar score of 8. 8, 5.8 per cent were delivered after 11 to 15 minutes of IDI with decreased mean apgar score of 7.6, and 3.7 per cent were delivered after over 15 minutes of IDI had mean apgar score of 7. 6. A short IDI appears to be advantageous from the standpoint of the newborn. Of the 144 infants, 6. 9 per cent of newbron infants(10) received intermittent positive pressure brething by face mask and 3.5 per cent(5) received oxygen through an endotracheal tube for the resuscitation. Neonatal death occured only 1(0.69%) case out of 144 infants, which caused by severe fetal. distre s asscciated with toxemia of pregnancy. There were no maternal death or anesthetic complication.. At the conclusion, the technique of general anesthesia with thiopental-succinylcholine-nitrous oxide-cxygen and/or supplemented with 0.5~1.0% of halothane was proved to be safe for mother and child, and showing a wide acceptance of general anesthesia for cesarean section(94%) at the Kyung Hee University Hospital.

김영길,장기홍,진상호,하청길 대한마취과학회 1976 Korean Journal of Anesthesiology Vol.9 No.1

Anesthetic experience with unilateral adrenalectomy for two patients (ll-year-old and 19- year-old female) with Cushings syndrome due to adrenocortical carcinoma has been reported. Anesthesia was induced with intravenous thiopental followed by nitrous oxide-oxygen-halothane and Pancuronium (Mioblock) for muscular relaxation. An endotracheal semi-closed circle absorption techniqne with controlled respiration was employed. The Patient tolerated well the anesthesia and surgery with appropriate cardiovascular control using hydrocortisone, whole blood and fluid replacement under continuous monitoring of B.P., E.C.G., C.V.P., and urine output. Importance of optimal preparation of the patient with Cushings syndrome, sufficient sedation, smooth induction, complete analgesia, good mucular relaxation, adequate alveolar ventilation and of proper cardiovascular control has been stressed and discussed together with the hazards of postoperative adrenal insufficiency.

Choriocarcinoma is a relatively rare malignancy of which characteristic is rapid metastasis to the other organs. It is related to the previous gestation or originated from the teratoma. Choriocarcinoma is mostly originated from the intrauterine chorionic villi, but it is rarely originated from the utreine cervix, fallopian tube, ovary, vagina and pelvic cavity. Primary choriocarcinoma of the fallopian tube is exceedingly rare and it is originated from ectopic tubal pregnancy, tubal migration from the intrauterine pregnancy or intratubal teratoma. Symptoms and signs of the choriocarcinoma originated from the ectopic pregnancy are abdominal pain, vaginal bleeding, palpable adnexal mass, positive pregnancy test and amenorrhea. Thus it is difficult to distinguish choriocarcinoma from ectopic pregnancy on the basis of symptoms before the microscopic diagnosis presented. Effective treatment of choriocarcinoma is chemotherapy. Additional operation is possible. β-HCG is a useful measure for the follow up. We experienced a 36-year-old multigravida Korean woman who was diagnosed as the rupture of ectopic pregnancy after left salpingectomy in our hospital and then confirmed primary choriocarcinoma of the fallopian tube without metastasis on microscopic finding. Postoperative chemotherapy was performed with methotrexate. The follow up of disease is still on going at two month intervals and she has remained healthy, We report this case with review of literatures.
