We reviewed 65 died patients admitted to emergency medical center of Dankuk University hospital after severe head trauma from January 1995 to December 1995. To predict the outcome after severe head injury, we analyzed patients according to the initial GCS score and the initial CT findings. The CT findings that we evaluated were the type of intracranial lesion(mass Vs diffuse lesion). midline shift(≥ 3mm), and compression status of basal cisterns. The irreversible brain damage was suspected from the conditions of low GCS score(GCS≤3-5) and the CT findings of ① diffuse lesions with obliteration of basal cisterns and ② mass lesions with midline shift more than 3mm and obliteration of basal cisterns. The patients with irreversible brain damage were almost died within 24 hours after injury. But the CT findings of ① pure mass lesion, ② diffuse lesion with mild compression of basal cisterns, and ③ mass lesion with midline shift and mild compression were supposed to the reversible brain damage, and the patients with these finding had long survival time more than 48 hours or 7 days.

The authors have analyzed 60 patients with severe head injury who defined as post-traumatic coma for 24 hours with Clasgow Coma Scale(GCS) score of 8 or less and admitted to emergency room of Dankook university hospital from January to June 1995 to evaluate the factors affecting GCS and autcome with initial CT findings. The results are summerized as follows; 1. The status with low GCS score was observed from ① intracranial mass, especially acute subdural hematoma(SDH) ② midline shift≥3mm ③ completely compressed mesencephalic cistern 2. The mortality was high in intracranial mass, especially in acute SDH 3. The mortality for patients with miline shift≥3mm was high regardless of a mass lesion, but there was no statistical significance. As the mesencephalic cistern was partially compressed, the midline shift≥3mm did not affect the mortalith. The outcome was good in the group of midline shift≥3mm with GCS 6-8. 4. If the mesencephalic cistern were compressed, especially in complete compression, the outcome was much more likely to be poor than cistern was normal. 5. The poor outcome was obtained from the patients with low GCS score and compression, the outcome was much more likely to be poor than cistern was normal. 6. The poor outcome was obtained from the patients with low GCS score and compressed mesencephalic cistern in initial CT findings.

This report is a retrospective clinical study of 60 patients with abdominal trauma admitted and treated at the department of emergency medicine of DanKuk University hospital during the period from January 1995 to December 1995. we obtained following results. 1) The sex distribution was 45 males(75%) and 15(25%) females with significant predominence in male(3:1), and the age distribution revealed high incidence in second to fourth decades(50%). 2) The cases of the abdominal trauma were traffic accident(80%) in most common, violence, fall down in order frequency. All were blunt trauma. 3) The clinical manifestations and physical examination were abdominal pain(92%), abdominal tenderness, rigidity, decreased bowel sound, rebound tenderness in order frequency. 4) The shock status on admission(below 80 mmHg in systolic) were 10 cases with high mortality(30%). 5) The hematocrit changes in serial check after admission were 36 cases(60%). 6) The diagnostic methods were abdominal paracentesis, simple X-ray, abdominal sonography, abdominal CT, and DPL(Diagnostic Peritoneal Lavage). The abdominal paracentesis showed positive 36 cases(63%) among 48 cases. Abdominal paracentesis was one of the valuable diagnostic method in abdominal trauma. The Abdominal CT was the best diagnostic method in solitary organ injury, but the diagnostic rate was very low(25%) in small bowel injury. 7) The injured intraabdominal organs were small bowel(41%), liver(30%), spleen(20%), and kidney(17%). 8) The commonly associated extraabdominal injury were chest trauma(30%), upper and lower extremity injuries(20%), head trauma(15%). 9) The overall mortality rate was 5%, in abdominal trauma with multiple injury.

I have comparative studied insurance system relating to Seamen's Accident Compensation comparing with the Seafarers Act. So, I want to suggest its improvement measures as the solving way of its problems. It is the legal system for the shipowner to compensate the crew under the missing of crew or the losing of personal article. Also, the shipowner must be the insured of seamen in order to perform the seamen's accident compensation entirely, and the insurance by the National Federation of Fisheries Cooperative Act and Korea Shipping Association Act musto be included to this insurance, and thus there is the social securing scope as well as living securing scope in this insurance. With regard to the security of the seamen's accident compensation as indicated in the aboves, the shipowner has secured its effectiveness by all kinds of insurance, making the crew as the insured. If the above-mentioned matters are generalized, the seamen's accident compensation standard is below the accident compensation standard of ground worker, and thus the necessity far improvement of the seamen's accident compensation system is required. Accordingly, as its improvement way is the tentatively named seamen's accident compensation insurance law to be presented as the law-making under the existing industrial accident insurance law in consideration with the speciality of crew. It is thought which there will have to be the legal and systematic procedures.

Severe head injury is associated with a stress response that includes hyperglycemia, which has been shown to worse outcome during cerebral ischemia. To better define the relationship between head injury and hyperglycemia, admission glucose level were analyzed in 150 head injured patients from January 1995 to December 1995. Our retrospective study demonstrated a higher glucose level in patients with low Glasgow Coma Scale(GCS) score, especially at 3-5 GCS score, compared to those with high GCS scores. Also a higher glucose level was noted in patients with vegetative state and dead than in those with good recovery and moderate disability. Hyperglycemia(serum glucose level≥200mg%) was associated with decreased level of consciousness and a poor outcome. We conclude that admission hyperglycemia is a significant indicator of severity of injury(p<0.001), but not significant predictor outcome from head injury. After controlling for the influence of the GCS score, glucose levels do not have an independent effect on outcome.

The assumptions of period checking policy for On-Line Quality Control presented by Taguchi are examined and his loss function and formulae are evaluated by simulation. New iterative procedures are proposed under Taguchi's loss and improved loss functions, respectively. Computational experiments are conducted for various combinations of parameter values and their results are discussed. Sensitivity analysis for assumption of random walk model is also illustrated with an example.

수명이 지수분포를 따를 때 정기검사 및 정시종결하에서 신뢰성 샘플링검사계획의 개발

서순근,김갑석 한국경영과학회 1996 한국경영과학회지 Vol.21 No.1

A Reliability Acceptance Sampling Plan(RASP) is developed for testing the exponential mean lifetime under the periodic(i. e., equally-spaced) inspection and Type I censoring. Under the periodic inspection, the exact sampling distribution of maximum likelihood(ML) estimator of mean can not be derived. Hence sample size and acceptance criterion are determined by the algorithm proposed on the basis of Monte Carlo simulation such that the producer's and consumer's risks are satisfied for given censoring time and number of inspections. In addition, the developed RASP is compared to other RASP's designed under the continuous inspection and under the periodic inspection in terms of sampling size, OC curve, and expected completion time, The effects for the RASP by the chosen inspection scheme are also discussed.

This paper presents new compromise ALT plan which is applied to situations that true relationship between stress and parameters is not known exactly. The assumed failure distribution of this study is one of location-scale family, i. e., exponential, Weibull, and lognormal distributions which have been ones of the popular choices of failure distributions. The method of applying the stress is constant, and the censoring mechanism is Type I censoring. Compared with existing compromise plans under true simple linear model in terms of statistical efficiency, the efficiency of new compromise plan is better than the corresponding other compromise ones in most cases. For case when true model is quadratic, this plan can be used without any severe loss in statistical efficiency. The proposed new compromise ALT plan is illustrated with a numerical example and sensitivity analyses are conducted to study effects of pre-estimates of design parameters.
