Background: It has been documented that certain prognostic factors may affect the outcomes of the old aged victims by trauma. Considering that trauma is the sixth most common cause of death in people over the age of 65 years and there is a rapid growth of elderly population, it is paramount to understand the prognostic factors when dealing with geriatric trauma patients. Hypothesis and Goals: It can be hypothesized that the prognostic factors should be determined independently between populations being consisted of different races, countries, socio-economic states, cultures, or so on. Thus, the study was designed to evaluate the factors affecting the outcomes of elderly Korean trauma patients. Methods: One hundred forty six patients aged over 65 years were retrospectively reviewed, who visited the Emergency Center of Korea University from January, 1997 to June, 1998. Of 146 patients, 7 were excluded due to discharge against advice or transfer to the other hospitals. Parameters analyzed were age, sex, mechanism of injuries, body region injured, Injury Severity Score (ISS), previous medical illness, hospital morbidity, duration of hospital stay, and cost. Each patient was classified into improved or not-improved group depending on the outcomes, and young-old or old-old group depending on the age. The factors affecting the hospital stay in improved patients were analyzed in the parameters of previous medical illness, hospital morbidity, multiple injuries, ISS, and age. All statistical tests were conducted with two-tailed levels of 0.05. Results: Of 139 patients, the mean age was 74±7.1 years, mean ISS 9.3±7.26, mean hospital stay 27±27.1 days. Most commonly injured body region was the extremities due to fall from a level surface. Rate of previous illness showed 0.94 medical diseases per person and were aggravated after trauma in 39 patients (60.9%). Hospital morbidity rate was 0.46 incidents per person. There were no differences in age and duration of hospital stay between the improved and the not-improved group. Substantial differences were noted in affected body region, incidence of previous illness, and hospital morbidity between the groups (p=NS). Not-improved group had higher ISS(p<0.05). ISS, previous illness and hospital morbidity affected the duration of hospital stay in the improved group. Hospital stay was 40±25.1 days in patients with ISS over 6 while 6±8.6 days in those with ISS 5(p<0.05). Hospital stay in the improved was 26±26.9 days while 31±24.8 days in the improved old-old group (p=NS). Hospital stay in the young-old minor trauma (ISS5) patients with previous illness and hospital morbidity was 26±10.1 days while 4±7.3 days in those without previous illness and hospital morbidity (p<0.05). Conclusion: Previous medical illness and hospital morbidity, not age, are predictive of outcomes of geriatric trauma patients with respect to hospital stay. As most of the hospital morbidity was a trauma-induced aggravation of previous medical illness and hospital morbidity contributing poor outcomes can be potentially avoidable, routine aggressive care for the geriatric trauma patients with previous medical illnesses is needed.

Coulomb’s theory has been usually used in practice for design of retaining walls. This theory assumed that the lateral earth pressure was a triangular distribution, because the point of applying the thrust could not be abtained straightforward. However, the results of laboratory and filed tests proved that the lateral earth pressure was not a triangular distribution. In this study, for gravity walls with inclined backface, backfilled by c - ø soils with inclined surface, an analytical method for earth pressure has been derived. This method applied the flat arching concept and the Coulomb’s wedge, under drained condition, for the cases of considering tension crack. In addition, this paper is dealt with comparing the new analytical solution with existed theories for some cases.

윤홍상,최완규,정문재 광주대학교 2001 産業技術硏究 Vol.15 No.-

인터넷의 급속한 보급을 기반으로 전자상거래가 활발하게 이루어지면서 이동에이전트에 대한 관심도 매우 높아지고 있다. 이동에이전트는 이를 활용하는 목적 및 분야에 따라 그 개념은 크게 달라질 수 있다. 하지만 이동에이전트와 관련된 보안에 관한 문제는 이를 이용하는 분야를 떠나서 사용자들에게 매우 큰 부담으로 남아있다. 특히 EC/EDI 분야에서 에이전트 보안은 매우 중요한 부분이라고 할 수 있다. 그러므로 인터넷과 같은 분산 개방형 네트워크 환경에서 자유롭게 이동하면서 정보를 검색, 전달하는 이동에이전트에 의한 개인의 정보 및 재산을 보호하기 위한 제어는 매우 중요한 부분이라고 할 수 있다. 본 연구에서는 옳지 못한 목적을 가진 에이전트 서로로부터 에이전트를 보호하고 또한 악의를 가지고 서버에 접근하는 에이전트로부터 중요한 자원을 보호할 수 있는 기법을 제시한다. In the resent years, the term mobile agent is probably one of the most overused words in many appliable areas of distributed open systems as electronic commerce and electronic data interchange, and it has very different meanings in the area of artificial intelligence, network management, or distributed systems. However, the use of mobile agent adds significant problems, primarily in the area of EC/EDI. Therefore it is very important to control the roaming agents to keep one's privacy or property in distributed open networks. In this paper, we introduce a mechanism to protect mobile agent itself from the malicious server he is visiting and also we introduce a mechanism to protect vital resources of the open systems as internet.

The adsorption behaviors of strontium and cesium ions on fly ash, natural zeolites, and zeolites synthesized from fly ash were investigated. The zeolites synthesized from fly ash had greater adsorption capabilities for strontium and cesium ions than the original fly ash and natural zeolites. The maximum adsorption capacity of synthetic zeolite for strontium and cesium ions was 100 and 154 ㎎/g, respectively. It was found that the Freundlich isotherm model could fit the adsorption isotherm. The distribution coefficients (K_(d)) for strontium and cesium ions were also calculated from the adsorption isotherm data. The distribution coefficients decreased with increasing equilibrium concentration of strontium and cesium ions in solution. By studying the removal of cesium and strontium ions in the presence of calcium. magnesium, sodium. potassium. sulfate, nitrate, nitrite, and EDTA (in the range of 0.01 - 5 mM) it was found that these coexistence ions competed for the same adsorption sites with strontium and cesium ions.

The present experiment was investigated on the effects of Sagunjatang extract on the humoral immune response of rabbit. In order to understand the immune respone of the extract, one of the experimental groups was treated with the antigen, E. coli Ry 13 suspension and the extract. And the serum separated from the treated group was analyzed. The results obtained were as follows : 1. The body weight of the rabbit treated with Sagunjatang extract was increased remarkably. 2. Sagunjatang extract did not affect the number of erythrocytes, however, it increased the number of WBC in small amount. It means that the extract activates the WBC related with producing antibody. 3. The synthesis of γ-globulin was stimulated by the Sagunjatang extract in the present experiment.
