The effect of ginseng administration on the patients of acute viral (B type) hepatitis has been oberved and the results were as follows. The albumin/globulin ratio of the ginseng administered group has significantly improved 4 weeks after admission while that of control group has not been improved suggesting that the ginseng might be effective in improving the protein metabolism. The thymol turbidity test again gave a similar result. Recovery of the disorder of bilirubin metabolism was also accelerated in the ginseng administered group compared with control group. The raised bilirubin value of the former returnedto the normal value 2 week after admission while that of the latter reached to normal 4-5 weeks after admission. However no significant difference of the bilirubin level between ginseng treated and non-treated groups could be observed. Cholesterol metabolism is also stimulated in ginseng administered group. The lowered cholesterol level of the ginseng group returned to normal 3-4 weeks after admission while that of latter reached to normal 5-6 weeks after admission. The raised S-GOT and S-GPT levels of the ginseng treated group returned to the normal value 3-4 weeks after admission while those of control group rehimed to normal in 5 weeks after admission suggesting that the ginseng improved impaired liver function. The improvement of the raised transaminase level seemed to be accelerate6 by the ginseng administration, however, no significant difference of the transaminase level between the ginseng treated and non-treated group could be observed. A significant effect of ginseng on the raised alkaline phosphatase level was observed. From the above results, it seemed that ginseng might stimulate the improvement of the disturbance of liver function, particularly at the early phase of its development of acute liver disease suggesting that panax ginseng might play a significant role in preventing the disease developing to be chronic.

Purpose: This study was conducted to assess the prevalence rate of, and the risk factors for pressure ulcers in critical patients at the time of intensive care unit (ICU) admission. Methods: We reviewed the electronic medical records of 2,107 patients who were admitted to the intensive care units in D university hospital between January 1 and December 31, 2012. The collected date were analyzed by ${\chi}^2$-test, t-test, and multi-variate logistic regression with forward stepwise selection using the SPSS program version 21. Results: The prevalence rate of pressure ulcers at the ICU admission was 23.7%. Risk factors significantly affecting pressure ulcers carrying were the age of 80 years or older (OR=3.70, 95% CI: 1.80~7.60), body weight less than 50 kg (OR=2.82, 95% CI: 1.74~4.56), sedated consciousness (OR=6.10, 95% CI: 3.57~10.40), use of ventilator (OR=1.60, 95% CI: 1.02~2.49), use of vasopressors (OR=1.53, 95% CI: 1.09~2.14), ICU admission via operation room (OR=0.49, 95% CI: 0.29~0.85), and hospital admission from nursing homes (OR=13.65, 95% CI: 3.02~61.72). Conclusion: The findings of this study suggested that the prevention efforts for pressure ulcers should be given in prior to ICU admission. Further research is necessary for developing nursing interventions for preventing pressure ulcers in the pre-ICU stage.

에너지 소비의 효율화를 위한 그린 기술로서 스마트 그리드와 지능형 교통 시스템 등이 주목받고 있다. 이러한 기술의 구현에는 다수의 센서, 액츄에이터 (actuator), 그리고 컨트롤러들이 필요하다. 이러한 구성요소들 간의 machine-to-machine (M2M)통신의 중요성은 높아지고 있다. M2M 통신의 특징은 다수의 machine-type-communication(MTC) 디바이스들이 참여하고, 통신 트래픽 패턴과 QoS 요구조건이 다양하다는 것이다. 이러한 M2M 통신을 효율적으로 지원하기 위한 호 수락 방법들에서는 동일한 시간관련 QoS 조건을 갖는 MTC 디바이스들을 클러스터 단위로 그룹핑하고, QoS 조건 만족여부에 따라 호 수락을 결정하는 방법을 제안하였다. 하지만 이 방법은 데이터 전송주기와 최대 전송지연 시간이 같을 경우에만 적용 가능하다. 본 논문에서는 이러한 제한 없이 사용할 수 있는 방법을 제안한다. 또한 전송 주기와 최대 전송지연 시간이 특별한 관계에 있을 때 최적화할 수 있는 호 수락 제어방법을 제안한다. 제안방법의 QoS 만족 적합성에 대한 증명을 제시하였고, 시뮬레이션을 통해 실제 동작 가능하고, 기존 방법들보다 호 수락 확률에서 우수함을 보였다.

본 논문에서는 기존 연구논문과 달리 성별의 차이, 계열별 학문특성의 차이, 전형유형별 차이 등이 학업성취도에 미치는 영향을 분석하였다. 남자는 인문사회계열에서 학생부위주전형이 우수하고, 자연계열에서는 수능위주전형이 우수했다. 여자는 인문사회계는 수능과 학생부를 모두 사용하는 전형이 우수하지만 큰 차이는 없었다. 그러나, 자연계열은 수능위주전형이 우수한 것으로 나타났다. 예체능계는 뚜렷한 특징을 보이고 있지 않지만, 수능위주전형이 우수한 것으로 나타났다. 인문사회계는 남자와 여자 모두 학업성취도에서 큰 차이를 보이고 있지 않으므로 입학사정관제가 정착되고 성과를 내고 있는 것으로 나타났다. 하지만 자연계는 남자와 여자 모두 학업성취도가 수능위주전형보다 낮게 나타나고 있다. 이는 자연계열에서 중요한 과목이 수학과 과학이므로 나타나는 현상이다. 이를 해결하기 위해서는 자연계열의 입학사정관제는 수학 및 과학의 기초학업능력을 반영하여 선발되어야 하고, 또한 입학 후 수학 및 과학의 기초학업능력을 향상시킬 수 있는 추수지도 방안이 반드시 필요한 것으로 보인다.

This study is designed to find clues to make a plan for efficient hospital bed utilization. Author has tried to estimate the level of appropriateness and to find out factors affecting intra-hospital variation of inappropriate bed utilization using modified Appropriateness Evaluation Protocol of which criteria are based on service intensity and patients' conditions. Systematic random sampling was done from the population of inpatients during one month in on university hospital. Data were collected by concurrent and retrospective medical record review and analysed by multiple logistic regression. In medical services, 83.5% of admission reveals appropriate and the level of inappropriate admission shows significant differences by patients' residence, type of department admitted to, admission 개\ulcorner, and length of stay. In surgical services, 97.3% and 34.7% are appropriate in location and timing of surgery respectively. Inappropriate timing of surgery differs significantly depending on patients' age, type of department admitted to, admission route, and length of stay. Sixty two percent of hospital days shows appropriate and the level of inappropriateness show marked differences by patients'age, type of services, admission routes, part of the month, part of the stay, and length of stay. Inappropriate hospital days are due to inappropriate level of care, premature admission, improper scheduling of diagnostic or therapeutic procedures, and problems in scheduling surgery in sequence. In conclusion, substantially high proportion of inappropriate hospital bed utilization was confirmed. To reduce it, it is necessary to develop alternative services with which can replace inpatient services, and to introduce utilization management system which may include internal peer review.

The purpose of this study is to identify any differences in academic records of students after they got into the Korea National College of Agriculture and Fisheries through the entrance exam. The target group was the students of 1,035 who enrolled from the year of 2012 to 2014 by the exams respectively, and this study compared those first year's records. As a result, this study found that their academic achievements have no significant differences statistically. With regard to the result, we could recognize that the average achievements of students are arithmetically high, who were accepted by admission officer's interview(talented students of agriculture and fisheries) and regular admission procedure to which the scholastic test result is applied. Accordingly, it is more desirable that we should rather focus on measures to improve the admission procedure that could contribute to academic achievements of students who are mostly accepted through the nonscheduled admission. It is pointless to focus on discussion that the achievement of students selected by a particular procedure is low. That kind of criticism proved groundless. Secondly, the study of the correlation between their admission records and after admission records of the freshmen in 2012 shows that a significant difference does not exist whereas those of in 2013 and 2014 has a slightly different statistically, though a coefficient of correlation was a mere 0.17. It account for this result that KNCAF has increased the applied-rate of highschool transcript from 33.3% to 50.0.% in admission procedure from the year of 2013. However, lowering the applied-rate of farming and fishing background is not everything as we consider the graduates' easy settling into rural area. It is a well-known fact that after graduation, the majority of students who have applied for a grace period of the delay in performing the obligation of farming and fishing, and of students who have paid the school expenses back came from ones with no sufficient foothold. This means that we should formulate a supporting policy for the students to settle into rural area smoothly after graduation if we keep the regulation of lowing the applied-rate of farming and fishing.

Purpose: Prolonged stay in the emergency department (ED), which is closely related with the time interval from the ED visit to a decision to admit, might be associated with poor outcomes for trauma patients and with overcrowding of the ED. Therefore, we examined the factors affecting the delay in the decision to admit severe trauma patients. Also, a multidisciplinary department system was preliminarily evaluated to see if it could reduce the time from triage to the admission decision. Methods: A retrospective observational study was conducted at a tertiary care university hospital without a specialized trauma team or specialized trauma surgeons from January 2009 to March 2010. Severe trauma patients with an International Classification of Disease Based Injury Severity Score (ICISS) below 0.9 were included. A multivariable logistic regression analysis was used to find independent variables associated with a delay in the decision for admission which was defined as the time interval between ED arrival and admission decision exceeded 4 hours. We also simulated the time from triage to the decision for admission by a multidisciplinary department system. Results: A total of 89 patients were enrolled. The average time from triage to the admission decision was $5.2{\pm}7.1$ hours and the average length of the ED stay was $9.0{\pm}11.5$ hours. The rate of decision delay for admission was 31.5%. A multivariable regression analysis revealed that multiple trauma (odds ratio [OR]: 30.6, 95%; confidence interval [CI]: 3.18-294.71), emergency operation (OR: 0.55, 95%; CI: 0.01-0.96), and treatment in the Department of Neurosurgery (OR: 0.07, 95%; CI: 0.01-0.78) were significantly associated with the decision delay. In a simulation based on a multidisciplinary department system, the virtual time from triage to admission decision was $2.1{\pm}1.5$ hours. Conclusion: In the ED, patients with severe trauma, multiple trauma was a significant factor causing a delay in the admission decision. On the other hand, emergency operation and treatment in Department of Neurosurgery were negatively associated with the delay. The simulated time from triage to the decision for admission by a multidisciplinary department system was 3 hours shorter than the real one.
