Purpose: To evaluate the antiadhesive effects and safety of an oxidized regenerated cellulose (Interceed) after thyroidectomy. Methods: Seventy-six thyroidectomized patients were prospectively randomized into two groups with regard to the use of Interceed. We evaluated each group for their adhesive symptoms using four subjective and four objective items at the 2nd week, 3rd and 6th month after thyroidectomy. All patients were examined for vocal cord motility by indirect laryngoscope at each period. Results: Total adhesion scores at each postoperative follow-up period decreased with time, but were not significantly different in each group. The median score for swallowing discomfort for liquid was significantly lower in the Interceed group than in the control group 2 weeks after surgery. In addition, the severity of skin adhesion to the trachea was reduced in the Interceed group compared with the control group 6 months after surgery. During the study, there were no adverse effects or significant differences in postoperative complications between the groups. Conclusion: Interceed appeared to be safe and effective in improving neck discomfort at early postoperative periods and preventing skin adhesion to the trachea 6 months after thyroidectomy.

Background: The initial history, physical examination, and ECG assessment should focus on identification of potentially serious noncardiac or cardiac disorders, including coronary artery disease, congestive heart failure, and electrical instability at the emergency room. additionally, it is essential to define disease severity, stability and need for emergency therapy. echocardiography is a useful tool for this purpose. especially Doppler echocardiography may be more sensitive and time-saving diagnostic tool for the evaluation of patients presenting with cardiogenic symptoms. So we evaluate the feasibility of the echocardiographic measurement by emergency physicain after short-term course. Method and Results: Twenty volunteers(10 male, 38.8±9.3 years) were included in the study for measurement of myocardial performance index and established parameters of ventricular function using conventional echo-Doppler methods. Myocardial performance index: (ICT+IRT)/ET, was obtained by subtracting ejection time(ET) from the interval between cessation and onset of the mitral inflow velocity to give the sum of isovolumic contraction time(ICT) and isovolumic relaxation time(IRT). The most of mean values of echocardiogrphic parameters were not significantly different between those of cardiologist and those of emergency physicians(p<0.01). The duration for measuring myocardial performance index was shortest among echocardiographic parameters. the validity of echocardiographic parameters measured by emergency physicians was proved relatively good. Conclusion: It is proved to be feasible for emergency physician to perform echocardiographic evaluation of ventricular function after short-term course

A prospective review of 53 multiple injured patients(ISS≥16) initially treated at local community hospitals and subsequently transported more than 50km to referral emergency center was completed. All injury mechanisms were blunt, and among them traffic accidents occupied the 54.7%. Revised Trauma Score ranged from 0 to 12 (mean, 10.4) and Injury Severity Score ranged from 16 to 50 (mean, 24.3). No prior notification of patient transfer to the referring facility were received in 52(98.1%) cases, and absent or very incomplete record were evident in 44 (83.0%) cases. The quality of care during initial stabilization and transport was evaluated by ATLS guideline for airway management, cervical immobilization, breathing support, treatment of shock, fracture immobiliaztion, neurologic evaluation, secondary assessment, life-threatening deficiencies were identified in 10(18.9%) patients and serious deficiencies in 32(60.4%). Most frequent departures from these standards involved failure to place a nasogastric tube before transport(58.5%), inadequate breathing support(30.2%), inadequate cervical immobilization(24.5%) and inadequate shock treatment(17.0%). This study demonstrates the need for education of emergency physicians about priorities in trauma management and ATLS courses. Furthermore guidelines for transport and interhospital communication must be established in rural area.

This study attempts to identify the difference of consumer’s preference of rewards divided by image of country of origin. And to investigate the moderating role of consumer’s effort in country of origin effect. In the experiment, participants showed the highest preference when rewards which has positive image related to country of origin were offered, followed by rewards of neutral image, and ones of negative image. In addition, the difference of preference between rewards of positive image and ones of negative image was strongly influenced by a lower degree of consumer’s effort compared to a higher degree of it. Lastly, after controlling rewards of neutral image, the difference of preference between this and rewards of positive image was strongly influenced by a degree of consumer’s effort. But the difference of preference between that and rewards of negative image was not influenced by it. The results indicate that extrinsic cue, country of origin, which is the new concept on research of rewards program is the important factor for drawing consumer’s responses effective for company.

보상물 선택맥락에 따른 차별적 보상물 선호에 관한 연구

본 연구는 Dhar와 Wertenbroch(2000)가 제시한 획득의 선택과업과 포기의 선택과업에 따라 실용적 속성과 쾌락적 속성으로 구분된 보상물의 선택결과가 어떻게 차별적으로 나타나는지 규명하고 있다. 특히, 지금까지 보상물선택에 있어 중요한 영향요인으로 작용해 온 소비자의 노력수준(Kivetz & Simonson, 2002)을 통제하였는데, 이를 통해 보상물선택에 영향을 줄 수 있는 또 다른 요인을 찾을 수 있게 되었다. 연구결과를 살펴보면, 먼저, 획득의 선택과업에서는 쾌락적 속성의 보상물보다 실용적 속성의 보상물에 대한 선호도가 높게 나타났다. 반면, 포기의 선택과업에서는 실용적 속성의 보상물보다 쾌락적 속성의 보상물에 대한 선호도가 높게 나타났다. 이러한 현상을 설명하기 위해 본 연구에서는 인간이 느끼는 부정적 감정의 일종인 죄책감(획득의 선택과업)과 경제학적으로 설명이 난해한 소비자행동을 심리학적인 측면에서 재해석한 손실회피(포기의 선택과업)이론을 사용하였다. 이러한 연구결과를 통해, 이론적 토대 위에서 고객 지향적인 보상물(customer-oriented rewards)을 디자인할 수 있는 기틀이 마련되었다. 한편, 고객보상프로그램 관련 연구자와 실무자에게 이론적, 실무적 시사점을 제공할 수 있게 되었고, 더불어 연구의 한계점을 통해 향후 연구방향을 제시할 수 있게 되었다. To achieve the research objectives, we investigated the main effects of the main strategic variables such as reward types on consumer decision making of rewards under the different two kinds of choice task to get rewards. This study aims to provide with marketing managers a customer value-based framework of reward program and some guidelines for the better management of the reward program. The results of this study show that under acquisition choice task, customers prefer utilitarian rewards than hedonic rewards. On the other hand, under forfeiture choice task, customers prefer hedonic rewards than utilitarian rewards. This result implys that the two theories such as guilty and loss aversion theory could be served as the underlying background for designing the customer-oriented rewards. At the end, the theoretical and practical contributions and limitations are discussed, and also the future research opportunity is suggested.

Amyloidosis is a disease resulting in deposition of amyloid in the body. The disease can be either primary or secondary. The amyloidosis of urinary bladder is more usually affected by primary amyloidosis and also very rare. The patient with primary amyloidosis of the bladder usually presents with gross hematuria. The amyloidosis resembles bladder cancer in cystoscopy. It can be confirmed by biopsy. The treatment consists of medication (e.g., steroid, antitumor agent, cholchicine, DMSO) and/or transurethral resection. The standard treatment is mephalan and prednisolone. A 49-year-old man complained of recently developed gross hematuria without abdominal pain. We examined urinary bladder cystoscope for gross hematuria. It revealed small bulging mass on trigone are a of bladder. Therefore we did bladder biopsy. Finally, it revealed bladder amyloidosis. The patient was improved by medication (mephalan 2mg and prednisolone 1 mg/kg po daily). We report an unusual case of amyloidosis involving bladder.

To evaluate the physiologic extent of pulmonary contusion and effect of PEEP therapy for pulmonary contusion, we studied 16 patients received PEEP therapy with pulmonary contusion from nonpenetrating chest trauma. Hemodynamic parameters including pulmonary vascular resistance index and intrapulmonary shunt fraction were calculated from standard measurement, and arterial oxygen tension was measured. Pulmonary vascular resistance index and intrapulmonary shunt fraction were increased in patient group. Arterial oxygen tension was decreased with increase of the intrapulmonary shunt fraction(R=0.75). Arter minimal PEEP therap(5-10 ㎝H₂O), pulmonary vascular resistance index was remained unchanged and intrapulmonary shunt fraction was decreased without significant changes of pulmonary hemodynamics. Increment of arterial tension was increased with decrease of intrapulmonary shunt fraction(R=0.43). Decreased stroke volume index suggested of cardiac injury such as cardiac contusion in patient group. These results of our study suggested that increased intrapulmonary shunt fraction caused arterial hypoxia in pulmonary contusion and arterial oxygen tension was increased as a result of reduced intrapulmonary shunt by PEEP therapy.
