Purpose : To shorten processing time for variety of medical affairs of the patient at the outpatient clinic of a big hospital is very important to qualify medical care of the patient. Therefore, patient's waiting time for drug delivery after doctor's prescription is often utilized as a strong tool to evaluate patient satisfaction with a medical care provided. We performed this study to investigate factors influencing patient satisfaction related with waiting time for drug delivery. Methods : The data were collected from July 21 to August 12, 1998. A total 535 patients or their families who visited outpatient clinics of Inha University Hospital were subjected to evaluate the drug delivery time and the level of their satisfaction related, which were compared with those objectively evaluated by Quality Improvement Team. The reliability of the scale was tested with Cronbach's alpha, and the data were analyzed using frequency, t-test, ANOVA, correlation analysis and multiple regression. Results : The mean drug delivery time subjectively evaluated by the patient (16.1 13.0 min) was longer than that objectively evaluated (10.9 7.6 min) by 5.2 min. Drug delivery time objectively evaluated was influenced by the prescription contents, total amount or type of drug dispensed, etc, as expected. The time discrepancy between two evaluations was influenced by several causative factors. One of those proved to be a patient's late response to the information from the pharmacy which the drug is ready to deliver. Interestingly, this discrepancy was found to be more prominent especially when waiting place for drug delivery was not less crowded. Other factors, pharmaceutical counseling at the pharmacy, emotional status or behavior of a patient while he waits for the medicine, were also found to influence the time subjectively evaluated. Regarding the degree of patient satisfaction with the drug delivery, majority of patients accepted drug delivery time with less than 10 min. It was also found to be influenced by emotional status of the patient as well as kindness or activity of pharmaceutical counselor. Conclusion : The results show that, besides prescription contents, behavior pattern or emotional status of a patient, environment of the waiting place, and quality of pharmaceutical counseling at the pharmacy, may influence the patient's subjective evaluation of waiting time for drug delivery and his satisfaction related with the service in the big hospital. In order to improve patient satisfaction related with waiting time for drug delivery, it will be cost effective to qualify pharmaceutical counseling and information system at the drug delivery site or waiting place rather than to shorten the real processing time within the pharmacy.

The purpose of this study was to investigate the relationships among trunk muscle, knee, and ankle strengths using Cybex770, the isokinetic muscle functioning measurement device. 41 K and Y University soccer players who did not have any experience about back pain or spine surgery were recruited as subjects. The results of the study were as follows. 1. Trunk extension was significantly higher than trunk flexion and muscle strength was diminished with increasing load speed. 2. Trunk flexion/extension ratio was well balanced at 30。/sec but this balance was broken with increasing load speed. 3. At 60。/sec of load speed, the knee extension and flexion of the left side were higher than those of the right side. 4. At 60。/sec of load speed, the ipsilateral muscle strengths of the left knee were well balanced but those of the right side were imbalanced. 5. At 60。/sec of load spped, the ratio of bilateral muscle strength of knee was -18.5±32.3% and this implies the possibility of knee injury. 6. Plantalflexion and dorsiflexion of the right ankle were higher than those of the left side, and dorsiflexion/plantalflexion ratio of the left side was higher than that of the right side. 7. The ratio of bilateral muscle strength of ankle at 60。/sec of load speed represented a balanced muscle development but this balance was broken with increasing load speed.8. There were partially significant relationships between trunk muscle and knee strengths. and between knee and ankle strengths. In conclusion, the trunk muscle strength of soccer player might be a very important factor to improve performance. In addition. a training technique which considering strength and speed is needed to develop not static but dynamic strength. This training not only develops well balanced muscle strength but also protects sport injury. Thus, the isokinetic training of trunk could improve the trunk muscle strength. and increase the ability of flexion/extension of knee and ankle.

Because of the merit of nonoperative management of blunt hepatic trauma, which is the avoidance of operative morbidity, the use of nonoperative management has been extended. However the indications for such treatment have not been sufficiently determined. To suggest possible criteria for nonoperative management, we reviewed 95 cases with blunt hepatic injuries which were confirmed by abdominal exploration or abdominal CT in Gyeong Sang National University Hospital from January 1992 to October 2000. Of the 95 patients, 38 patients were treated with operation and 57 patients treated with nonoperative management. We analyzed the patients for age, sex, cause of injury, injured organ, injury grade, transfusion amount, and shock on admission, complications and mortality. The results are as follows; 1) The peak incidence of age was in the 3rd decade (20%), and the male-to-female ratio was 3:1. 2) The most frequent injury mechanism was traffic accidents (40, 42%). 3) The most frequently used diagnostic modality was abdominal CT (95 cases) in the nonoperative and the operative group. 4) On the liver injury scale of the American Association for the Surgery of Trauma (AAST), 13 were grade I, 18 were grade II, 10 were grade III, 13 were grade IV, and 3 were grade V in the nonoperative group ; 1 were grade I, 6 were grade II, 18 were grade III, 8 were grade IV, 4 were grade V, and 1 were grade VI in the operative group. 5) Between the nonoperative and the operative groups, there were significant differences in the systolic blood pressure in the first 8 and 24 hours, transfusion amount, and GOT/GPT level (p$lt;0.05). 6) In comparison of complication, there were 3 cases of heaptic abscess,1 case of intrahepatic hematoma, 1 case of bile leakage, 1 case of rebleeding in operative group (15.7%). There were 2 cases of intrahepatic abscess, 2 cases of intrahepatic hematoma, 4 cases of biloma, 1 case of subcapsular hematoma in nonoperative group (15.7%). In mortality cases, 6patients died in operative group. Among them, 5patiens died from DIC (disseminated intravascular coagulation) and multiorgan failure, 1patient died from ARDS (adult respiratory distress syndrome) in operative group and 2patients died from hypovolemic shock in nonoperative group. In conclusion, i) nonoperative management may be considered as a first choice in children and adults with blunt abdominal trauma and stable vital signs. ii) Patients with hemodynamically stable hepatic injury 8 hrs after resuscitation, even with an AAST OIS grade 4 injury, may be candidates for nonoperative management.

이근대,홍성수,박진환,안병현 釜慶大學校 2000 釜慶大學校 論文集 Vol.5 No.-

The effect of pigment-resin-solvent interaction on dispersion of pigment has been studied. The solubility parameter of TiO_2 pigment, determined in terms of suspension behavior of pigment in various solvents, was 10.27 (cal/cc)^1/2(δ_d = 8.23, δ_p = 3.45, δ_h = 5.10). The solubility parameter of Acryloid B-44, determined using rheological parameters of resin solution in different solvent, was 9.4 (cal/cc)^1/2. The solvent showing weaker interaction with pigment increased the adsorption of resin on to the pigment, resulting in higher dispersibility and higher storage stability of dispersion.

Mach peening treatment is one of the various kinds of techniques to improve the fatigue properties. The mach peening process gives high-level work hardening and compressive residual stress near the surface layer, improving the fatigue strength. In addition, this treatment reduces slip bands that initiate the fatigue cracks near the surface. During impingement, a plastic indentation surrounded by a plastic zone is formed. Mach peening treatment characteristic is less energy consumption and is an environmental friendly processing methods that is not accompanied by pollution. It is machining process that can prevent fatigue fracture beforehand in structure using already as well as process of production. The test results showed that fatigue crack propagation delay appeared by drilling type 43%, mach peening type 110%.

The purpose of this study is to compare nerve regeneration over a 5mm gap, the gap being bridged by either a polyurethane-silicone-heparin composite tube or an isotopic reverse nerve autograft. Polyurethane-silicone-heparin composite tube was used to bridge a 5mm gap between the proximal and distal nerve stumps of sciatic nerve of rat. Inner surface of composite tube was coated with hearin. The proximal and distal nerve stumps were introduced into each end of the tube and were held in place by one or two epineurial sutures. Nerve regeneration through the composite tubes after 12weeks, as evidenced by functional walking track analysis and light microscopy, was equally or better successful than nerve regeneration by isotopic reverse nerve autograft.

연구목적 : 세계적으로 널리 사용되는 우울증 척도인 the Center for Epidemiologic Studies Depression Scale(CES-D)을 이용하여 지역사회 주민의 우울증상의 정도를 평가하고, 우울증상의 위험요인을 분석하고, 한국인에서 우울증상의 요인구조를 알기 위해 본 연구를 실시하였다. 방 법 : 경기도 일 농촌 지역의 30세 이상 주민에 대해 무작위 군집 집락 추출을 실시하였고, 훈련된 면담원들이 가정 방문을 통하여 면접 및 자기보고 검사인 CES-D를 실시하였다. 총 1,315명에서 응답을 하였고 응답율은 59.3%이었다. 결 과 : CES-D에 의한 우울증 점수는 0∼5점이 57%정도를 차지하였고, 평균 점수는 남자 7.8점 여자 9.5점으로 비교적 낮은 편이었다. ANCOVA 분석 결과 비결혼, 저학력, 여성이라는 위험요인은 독립적으로 우울증상을 악화시키는 요인이었으나 연령은 통계적으로 유의하지 않았다. CES-D 결과를 요인분석을 시행한 결과 4가지 요인이 추출되었는데 우울증상 및 신체증상이 한 개의 요인으로, 다른 나라에서 보고되지 않는 정서적 고통이 별도의 요인으로 추출되었다. 결 론 : 국내 역학 조사에서도 외국과 유사한 우울점수 및 위험요인이 확인되었으나 우울증의 요인에서는 특이한 요인이 추출되었다. 한국인에 독특한 우울 반응에 관한 추가 연구가 필요하다. Objectives :The rates, correlates, and factor structure of depressive symptoms in a Korean rural sample were examined using Korean version of the Center for Epidemiologic Studies Depression Scale(CES-D). Methods : Door to door visiting survey was conducted by trained interviewers. A random cluster sample of 1,315 respondents, aged 30 and over completed the CES-D scale along with additional sociodemographic questionnaire. Results : In this sample, mean CES-D score of male and female were 7.8 and 9.5, respectively which were lower than those reported previously. Symptoms of depression were most common among the less educated, non-married and female according to ANCOVA. Age was not a significant risk factor for depressive symptoms. Different factor structures emerged from this sample as compared to other studies using this approach. Somatic symptoms and affective symptoms were combined as one factor and emotional hardship emerged as a separate factor. Conclusion : Symptoms scores and risk factors were similar to the results reported in other countries but unique factor structures were found in this study. Further research is needed about the Korean depressive symptomatology and related areas.

본 연구에서는 주위 환경 열화에 따른 복합절연재료의 절연특성과 수명을 향상시키기 위해 고온에서 흡습량을 변화시켰을 때와 탈습량을 변화시켰을 때 흡십시료와 탈습시료의 전기적 특성 및 기계적 특성을 조사하였다. 유리섬유 각층의 흡습상수는 각각 1층에서 0.0117, 2층에서 0.0123, 3층에서 0.0152를 나타냈다. 전기적 특성 및 기계적 특성은 복합재료의 흡습에 따라 크게 떨어졌다. 70℃에서 습기가 완전히 건조되어도 흡습전의 전기적 및 기계적 특성을 얻기가 어려운 것으로 나타났다. 수분에 의해 발생한 복합절연재료내에 존재하는 많은 결함들은 에폭시 메트릭스와 필라사이에 존재하였다. The electrical and mechanical properties of moisture absorbed and moisture desorbed specimens were investigated to improve the insulating characteristics and the reliability of composite materials against environment aging. Moisture absorption constants with the layers of glass fiber showed 0.0117 in 1 layer, 0,0123 in 2 layer and 0.0152 in 3 layer, respectively. Although moisture was removed at 70℃, it was impossible to obtain the initial electrical and mechanical properties. Many defects induced by moisture were observed at the interface between epoxy matrix and filler in composite materials.
