  • Electrolytic recovery of gold and silver from diluted solutions has at first been applied nearly 100 years ago. Compared with other recovery techniques electrolytic treatment offers several advantages. But to achieve high space-time yields special constructions of electrolytic cells for improved mass transfer are necessary. Ex-tended cathode surface areas and vigorous agitation are important features. Gold and silver recovery by use of newly developed electrolytic cell constructions - rotating tubular bed reactor and impact rod reactor - has been described. Calculations based on industrial application during several years are confirming that electrolytic recovery of precious metalss from diluted solutions has been operated in a very economic way.

  • Objective : The purpose of this study was to investigate the reliable factors influencing the surgical outcome of the patients with traumatic acute subdural hematoma (ASDH) and to improve the functional outcome of these patients. Methods : A total of 256 consecutive patients who underwent surgical intervention for traumatic ASDH between March 1998 and March 2008 were reviewed. We evaluated the influence of perioperative variables on functional recovery and mortality using multivariate logistic regression analysis. Results : Functional recovery was achieved in 42.2% of patients and the overall mortality was 39.8%. Age (OR=4.91, p=0.002), mechanism of injury (OR=3.66, p=0.003), pupillary abnormality (OR=3.73, p=0.003), GCS score on admission (OR=5.64, p=0.000), and intraoperative acute brain swelling (ABS) (OR=3.71, p=0.009) were independent predictors for functional recovery. And preoperative pupillary abnormality (OR=2.60, p=0.023), GCS score (OR=4.66, p=0.000), and intraoperative ABS (OR=4.16, p=0.001) were independent predictors for mortality. Midline shift, thickness and volume of hematoma, type of surgery, and time to surgery showed no independent association with functional recovery, although these variables were correlated with functional recovery in univariate analyses. Conclusion : Functional recovery was more likely to be achieved in patients who were under 40 years of age, victims of motor vehicle collision and having preoperative reactive pupils, higher GCS score and the absence of ABS during surgery. These results would be helpful for neurosurgeon to improve outcomes from traumatic acute subdural hematomas.

  • The purpose of this study was to investigate the relationship between the cumulative fatigue of trunk muscles and the period of recovery time during repetitive lifting and lowering task with two different frequencies(4 times/min and 6 times/ min). Eight healthy males with no prior history of LBD(low back disorders) volunteered for this study. Subjects had 2, 3, 4, and 5 minutes recovery time respectively while they were preforming the lifting and lowering task at 15% level of MVC. EMG signals from six trunk muscles were collected and the fatigue level was analyzed quantitatively. In results, the fatigue levels of LES(left elector spinae), RLD(right lattissimus dorsi), LLD(left lattissimus dorsi), RRA(right rectus abdominis) and LRA(left rectus abdominis) were recovered when 3 minutes recovery time was given at 4 times/min frequency. However, the fatgue level of RES(right elector spinae) was recovered when 4 minutes recovery was given. On the other hand, when 6 times/min frequency was used, the RLD, LLD, RRA and LRA were recovered at 5 minutes of recovery time. But for RES and LES, it took longer than 5 minutes to be recovered. This results can be applied to design the adequate length of recovery time to control the cumulative fatigue of trunk muscles in industry with repetitive lifting and lowering task.

  • The purpose of this study is to prove that the appropriate fit between service failure and recovery strategy can efficiently maximize customer satisfaction and behavioral intention, by using the prepared scenario through comprehensive approach concerning how the expectation level of service recovery has influence on perceived fairness, satisfaction and behavioral intention of service recovery based upon size in case of service failure. This study has been conducted by way of selection of filling-up type questionnaires for customers themselves who have experience in service failure out of customers who can easily visit family and hotel restaurants, that is, domestic restaurants in Seoul area, $June{\sim}August$ 2004, by setting factorial design of 2(control, severeness)$\times$3(distributive fairness, procedural fairness, mutual relational fairness)$\times$2(customer satisfaction, customer behavior). The survey was performed on the customers who visited common restaurants, family restaurants, hotel restaurants, etc. mainly in Seoul, and total 600 sheets of questionnaires were distributed and 496 sheets of them were returned(82.67% of return ratio). Research findings are as follows; First, perceived recovery justice has an effect on customer satisfaction and behavioral intention. Second, customer satisfaction and restaurant satisfaction have positive influence on behavioral intention. The results will be helpful for them to develop a further service failure and recovery framework. For service marketing managers, the results will suggest specific guidelines for establishing service recovery strategies.

  • Relaxed Static Stability(RSS) has been applied to improve flight performance of modern version supersonic jet fighters. Flight control systems are necessary to stabilize an unstable aircraft and to provide adequate handling qualities. Also, flight control systems of modern aircraft employ many safety measure to cope with emergency situations such as a pilot unknown attitude flight conditions of an aircraft in night flight-testing. This situation is dangerous because the aircraft can lose if the pilot not take recognizance of situation. The system called the "Pilot Activated Recovery System" or PARS, provided a pilot initiated automatic maneuver capable of an aircraft recoveries in situations of unusual attitudes, speed and altitude. This paper addresses the concept of PARS with AARS(Automatic Attitude Recovery System), ATCS(Automatic Thrust Control System) and MARES(Minimum Altitude Recovery Estimation System), and this control law is designed by nonlinear control law design process based on model of supersonic jet trainer. And, this control law is verified by real-time pilot evaluation using an HQS(Handling Quality Simulator). The result of evaluation reveals that the these systems support recovery of an aircraft unusual attitude and speed, and improve a safety of an aircraft.

  • 자연재해로 인한 사회기반시설물 피해를 저감시키기 위해서는 피해발생 초기 대응 및 신속한 복구가 중요하나, 현재는 현장인력의 상황전파에 초점을 맞추고 있으며 긴급 복구를 수행하기 위한 기술적 지원은 부족한 실정이다. 본 논문에서는 피해상황에 적합한 복구 방법을 도출하여 효율적인 자원분배를 수행하기 위한 웹기반 재난피해복구지원시스템 및 신속한 복구 자원을 요청하기 위한 전자문서 개발에 대해 설명한다. 획득된 현장의 피해정보는 미리 구축된 피해복구 시나리오에 따라 적절한 피해복구 공종 및 공법을 도출하게 되며, 복구 수행을 위한 자원을 할당하여 전자문서를 거쳐 신속하게 해당 복구자원 지원을 요청하도록 하였다. 필요한 복구자원의 식별과 신속한 전파는 재해의 대응과 긴급복구에 큰 도움이 될 것으로 판단된다.

  • 현재까지 국내에서 진행되어 온 서비스 실패와 회복 관련 연구들은 한국인의 정서적인 측면을 많이 고려하지 않았다. 한국인의 특성 상 이러한 감정적인 측면이 서비스 회복과정에서 작용할 수 있음에도 불구하고 대부분의 선행연구들은 기존에 해외문헌에서 주로 다루어진 변수들만으로 연구를 진행하였다. 그러나 실제 국내의 서비스 상황에서 발생하는 서비스 회복 과정에서는 소비자가 지각하는 정이라는 개념이 작용하는 경우가 많다. 이에, 관련 연구의 이해의 폭을 넓히고, 정이라는 개념을 실무에 적용하기 위해서는 추가적인 연구결과가 필요하다고 판단하였다. 따라서 본 연구에서는 기존연구의 한계점을 고려하여 서비스 회복상황에서 지각된 공정성과 고객이 지각하는 서비스제공자에 대한 정의 역할을 함께 살펴보았다. 이를 통해 국내 고객관점에서의 서비스 실패 상황에 적합한 서비스 회복모형에 대해서 고찰할 수 있는 계기를 마련하였다. 본 연구의 결과를 통해 단순히 서비스 회복 노력의 공정성뿐만 아니라 서비스 실패 후 회복과정에서 고객이 지각하는 정이라는 한국인 고유의 감정의 조절효과를 살펴봄으로써 고객의 이해심을 구할 수 있는 진심어린 회복노력의 중요성을 확인할 수 있다.

  • Purpose: The aim of study was to investigate relationship between compliance and recovery of patients with osteoarthritis of the knee patients after knee arthroplasty. Methods: 193 patients living in Seoul were participated in this study. Data were collected using the Knee Society Clinical Rating System and Medical Outcomes Study Short Form 36(SF-36) and analyzed by ANCOVA, t-test, and repeated measure ANOVA. Results: There was a significant difference of physiological recovery based on the number of co-morbidity patients have. Physical recovery level was different according to age, religion, and the number of co-morbidity. Age and education level of patients were different in emotional recovery. The level of physiological and physical recovery were significantly different consistent with compliance. Compared to preoperative scores, physiological and physical scores showed significant improvement at six weeks, three months, and six months after surgery while emotional scores did not showed significant improvement. Conclusion: The results of this study suggest that nursing interventions to increase compliance are needed for better recovery of patients after knee arthroplasty.
