Purpose: In terminally ill cancer patients, accurate prediction of survival is necessary for clinical and ethical reasons, especially in helping to avoid harm, discomfort and inappropriate therapies and in planning specific care strategies. The aim of the study was to investigate prognostic factor of dying patients. Methods: We enrolled the terminal cancer patients from Kangnam St. Mary's Hospital from 2004 until their death. We observed symptoms shown in dying patients and assess 17 common symptoms shown in terminally ill cancer patients, performance status, pain and analgesic use. Results: Average period from hospitalization to death was 11.7 days. The most important prognostic factor is performance status (KPS), average KPS at enrollment is 48% and at last 48 hours is 25%. Physical symptoms that have significant prognostic importance are poor oral intake, weakness, constipation, decreased Karnofsky performance status, bed sore, edema, jaundice, dry mouth, dyspnea. Dying patients showed markedly decreased systolic blood pressure, cyanosis, drowsiness, abnormal respiration, death rattle frequently at 48 hours before death. Conclusion: If we assess the symptoms more carefully, we can predict the more accurate prognosis. The communication about the prognostic information will influence the personal therapeutic decision and specific care planning.

This study was carried out to investigate the post stroke depression (PSD) occurrence in acute stroke patients and to identify the factors that influence PSD. The study subjects were 104 adults in their 20s or older who were scheduled to be discharged due to inpatient treatment for ischemic stroke in two hospitals. Data were collected using Post Stroke Depression Scale for PSD, Multidimensional Scale of Perceived Social Support for social support, National Institutes of Health Stroke Scale for stroke severity, and Modified Rankin Scale for disability. The average length of stay after stroke onset of the study subjects was 5.9±2.1 days, and 79.8% were within 7 days. Stroke severity score was an average of 2.4±2.5 out of 42 points, and disability score was an average of 1.6±1.1 out of 6 points. Among the subjects, 32.7% had mild or more severe depression after stroke. The subjects with no religion, severe disability, high stroke severity, and less family support had a higher likelihood of experiencing PSD. These results show that depression can appear in the early stages of stroke onset. Therefore, it is necessary to develop nursing guidelines for depression intervention after acute stroke, including continuous early assessment of depression from the acute phase of stroke and religion or family support.

실시간 시스템이란 시간적인 제한을 가지고 작업 수행 결과의 정확도가 보장되는 시스템으로 경성 실시간 시스템과 연성 실시간 시스템으로 분류된다. 최근 분산 실시간 분야에서 새로운 패러다임으로써 폭넓게 활용되기 시작한 실시간 객체 모델인 TMO는 Kane Kim과 Kopetz에 의해 처음 제안되었다. TMO 모델은 경성 또는 연성 실시간 응용과 병렬 컴퓨팅 응용 프로그램에서 사용 될 수 있으며, 시스템의 기능적인 면과 시간 조건 수행 모두를 명확히 정의할 수 있다. TMO의 네트워크로 구성되는 실시간 분산 환경에서의 실행을 위해 몇 개의 TMO 실행 엔진이 개발 되었는데, 그 중에서 LTMOS라는 리눅스 기반의 연성 실시간 미들웨어 엔진이 한국외대 RTDCS lab.에서 개발되었다. 하지만 LTMOS의 실시간 시스템 수행 중 작업량의 과부하로 인한 deadline 위반이나, 시스템간의 분산 IPC 통신에 있어서 Channel Traffic이 빈번한 경우 실시간 시스템을 유지할 수 없다는 문제점들을 갖고 있다. 이러한 문제점들을 해결하고 조금 더 효율적인 실시간 시스템을 유지하기 위해서, TMO 프로그램의 resource 정보를 담고 있는 ODS(Object Data Store)만을 다른 노드에 있는 자신의 TMO 프로그램 Replica로 이주해서 실시간 로드 밸런싱을 구현하는 기법을 사용하였다. 이에 본 논문에서는 TMO 프로그램들의 deadline 위반 및 Channel Traffic 부하를 감지할 수 있는 Node Monitor와 최적의 노드를 선별할 수 있는 Migration Manager를 새롭게 추가하였고, 쓰레드들의 스케줄러인 WRMT에 이주 작업을 하기 위한 부가적인 기능을 구현하였다. 2D 이미지의 관측점을 줄여 계산량을 대폭 감소시키는 장점을 갖는다.것으로 조사되었으며 40대 이상의 연령층은 점심비용으로 더 많은 지출을 하고 있는 것으로 나타났다. 4) 끼니별 한식에 대한 선호도는 아침식사의 경우가 가장 높았으며, 이는 40대와 50대에서 높게 나타났다. 점심 식사로 가장 선호되는 음식은 중식, 일식이었으며 저녁 식사에서 가장 선호되는 메뉴는 전 연령층에서 일식, 분식류 이었으며, 한식에 대한 선택 정도는 전 연령층에서 매우 낮게 나타났다. 5) 각 연령층에서 선호하는 한식에 대한 조사에서는 된장찌개가 전 연령층에서 가장 높은 선호도를 나타내었고, 김치는 40대 이상의 선호도가 30대보다 높게 나타났으며, 흥미롭게도 30세 이하의 선호도는 30대보다 높게 나타났다. 그 외에도 떡과 죽에 대한 선호도는 전 연령층에서 낮게 조사되었다. 장아찌류의 선호도는 전 연령대에서 낮았으며 특히 30세 이하에서 매우 낮게 조사되었다. 한식의 맛에 대한 만족도 조사에서는 연령이 올라갈수록 한식의 맛에 대한 만족도는 낮아지고 있었으나, 한식의 맛에 대한 만족도가 높을수록 양과 가격에 대한 만족도는 높은 경향을 나타내었다. 전반적으로 한식에 대한 선호도는 식사 때와 식사 목적에 따라 연령대 별로 다르게 나타나고 있으나, 선호도는 성별이나 세대에 관계없이 폭 넓은 선호도를 반영하고 있으며, 이는 대학생들을 대상으로 하는 연구 등에서도 나타난바 같다. 주 5일 근무제의 확산과 초 중 고생들의 토요일 휴무와 더불어 여행과 엔터테인먼트산업은 더욱 더 발전을 거듭하고 있으며, 외식은 여행과 여가 활동의 필수적인 요소로써 그 역할을 일조하고 있다. 이와 같은 여가시간의 증가는 독신자들에게는 좀더 많은 여유시간을 가족을

Purpose: Preimplantation genetic diagnosis (PGD), also known as embryo screening, is a pre-pregnancy technique used to identify genetic defects in embryos created through in vitro fertilization. PGD is considered a means of prenatal diagnosis of genetic abnormalities. PGD is used when one or both genetic parents has a known genetic abnormality; testing is performed on an embryo to determine if it also carries the genetic abnormality. The main advantage of PGD is the avoidance of selective pregnancy termination as it imparts a high likelihood that the baby will be free of the disease under consideration. The application of PGD to genetic practices, reproductive medicine, and genetic counseling is becoming the key component of fertility practice because of the need to develop a custom PGD design for each couple. Materials and Methods: In this study, a survey on the contents of genetic counseling in PGD was carried out via direct contact or e-mail with the patients and specialists who had experienced PGD during the three months from February to April 2010. Results: A total of 91 persons including 60 patients, 49 of whom had a chromosomal disorder and 11 of whom had a single gene disorder, and 31 PGD specialists responded to the survey. Analysis of the survey results revealed that all respondents were well aware of the importance of genetic counseling in all steps of PGD including planning, operation, and follow-up. The patient group responded that the possibility of unexpected results (51.7%), genetic risk assessment and recurrence risk (46.7%), the reproduction options (46.7%), the procedure and limitation of PGD (43.3%) and the information of PGD technology (35.0%) should be included as a genetic counseling information. In detail, 51.7% of patients wanted to be counseled for the possibility of unexpected results and the recurrence risk, while 46.7% wanted to know their reproduction options (46.7%). Approximately 96.7% of specialists replied that a non-M.D. genetic counselor is necessary for effective and systematic genetic counseling in PGD because it is difficult for physicians to offer satisfying information to patients due to lack of counseling time and specific knowledge of the disorders. Conclusions: The information from the survey provides important insight into the overall present situation of genetic counseling for PGD in Korea. The survey results demonstrated that there is a general awareness that genetic counseling is essential for PGD, suggesting that appropriate genetic counseling may play a important role in the success of PGD. The establishment of genetic counseling guidelines for PGD may contribute to better planning and management strategies for PGD.

Purpose : Febrile convulsions are a common pediatric neurological disease, and it is important to prevent such a disease by controlling the risk factors that may recur. A recent report states that influenza virus infections have a high probability of a relationship with febrile convulsions; therefore, it is necessary to identify the clinical properties of febrile convulsions in relation to domestic influenza virus infections. Methods : Between November 2005 and February 2008, children hospitalized because of febrile convulsions and subsequently confirmed to have influenza infections were enrolled as subjects (patient group, n=11). The control subjects were those admitted with influenza virus infections but no febrile convulsions (control group 1, n=46) and those who developed febrile convulsions without influenza virus infection (control group 2, n=53). Results : The patient group showed a higher maximum body temperature ($39.3{\pm}0.5^{\circ}C$), more histories of past febrile convulsions (72.7%), and a shorter total duration of fever ($2.9{\pm}1.2$ days) than control group 1. When multivariate analysis was performed, the probability of febrile convulsions was found to be as high as 225.9 times in patients who had influenza virus infections with a past history of febrile convulsions (OR=225.9, 95% CI: 1.7-4780.0, P<0.05). When patients with febrile convulsions were compared based on the symptoms of influenza virus infections, the patient group showed a shorter duration of fever ($0.9{\pm}0.7$ days) before convulsion than control group 2; these convulsions were mostly a recurrence of febrile convulsions. When multivariate analysis was performed, the cases with a past history of febrile convulsions showed 5.5 times (OR=5.5, 95% CI: 1.2-25.1, P=0.03) the probability of convulsions when infected with the influenza virus, and this probability decreased by 0.3 times over one-day increments of the febrile period until febrile convulsions (95% CI: 0.1-0.9, P=0.02). Maximum body temperature, total duration of fever, family history of febrile convulsions, and complex febrile convulsions did not show a statistical significance. Conclusion : In cases of pediatric influenza virus infection, the past history of febrile convulsions could be identified within the risk factor of recurrent febrile convulsions. Therefore, influenza vaccination of children having a past history of febrile convulsions will be helpful to avoid the recurrence of these convulsions.

Purpose : Hemophagocytic lymphohistiocytosis (HLH) is a rare but fatal disorder characterized by fever, splenomegaly, pancytopenia, and hemophagocytosis in the bone marrow and other tissues. In this study, we investigated the clinical manifestations and prognostic factors in patients with HLH. Methods : We retrospectively analyzed the data from 29 patients who were diagnosed whit HLH in the Severance Children's Hospital from Jan. 1996 to Feb. 2007. Results : The median age at diagnosis was 3.8 years (range 0.1-12.2). The ratio of male to female patients was 1.1:1. The 5-year overall survival rate was 55.2% with a median follow-up duration of 32 months. In a multivariate analysis, the duration of fever before admission (survival vs. non-survival, 6.5 days vs. 14 days, P=0.010), the interval from the day of fever onset to the day of initiation of etoposide (survival vs. non-survival, 10 days vs. 35 days, P=0.002) and the presence of neurologic symptoms (survival vs. non-survival, 1 case vs. 7 cases, P=0.010) were independent, poor prognostic factors of HLH. EBV infection, gender, and the level of serum ferritin had no relations to the poor prognosis of the disease. Conclusion : This study showed that the presence of neurologic symptoms and a longer duration of fever were related to a poor prognosis. Therefore, if a patient develops neurologic symptoms and the duration of fever is prolonged, a prompt diagnostic approach and aggressive treatment for HLH are necessary.

This study was conducted to compare the health behaviors of patient s before and after a stroke and propose health education program to reduce risk factors related to stroke recurrence. Data were collected from eighty- eight stroke patients registered at the Gyeongju-si Health Center between July 1, to August 30, 1999, by interviewing patients from a prepared structured questionnaire, which included questions on that patients ' general characteristics, health- related behaviors, family-related characteristics, and pre- and post - stroke health status. Smoking rate of 51.1% before stroke reduced to 25.0% after stroke; drinking rate of 52.3% before stroke reduced to 17.0% after stroke; daily smoking amount of 20.1 packs per day before stroke significantly reduced to 14.9 packs per day after stroke; and daily drinking amount of 92.4ml before stroke significantly reduced to 23.7ml after stroke. Smoking rate according to sex showed a marked decrease in the male subjects, but 31.6% still smoked even after their stroke. Among the female subjects, smoking rate of 16.1% before stroke reduced to 12.9% after stroke. Observation of the change in health- related behaviors of stroke patient s showed significant change in smoking rate, drinking rate and intake of regular meals etc. of patient s with a spouse and patients who received preventive health education. Health education on quitting smoking, temperance, low fat diet, exercise and regular meals for stroke patient s are needed, and public and private organizations can do their part in development and providing continuing health education programs and health education.

Roads, like bikeways, parkways and walks, are to be just capable of supporting light traffic and traveling public, but they are required to be human friendly and environmental-oriented. Lately soil-solidifier mixture, a kind of soil-cement, has developed and has been applied to the recycling and environment-oriented pavement as the surfacing material. Soil-solidifier pavement structure has been designed by only experience. To design this pavement mechanically, it is necessary to find out basic engineering properties of soil-solidifier mixture. This study focuses on finding out mechanical characteristics of the mixture according to mixture proportions and aging. Test molds with various mixture proportions are made, and then unconfined strength tests are performed for test molds with aging of the mixture. As the result of this study, it is found that the strength of the mixture increases with amount of cement and that maximum strength is achieved at 6%$\sim$8% of the ratio of solidifier and water. The strength increase rapidly until 14 days, after then slowly. After 28 days the strength of the mixture approaches to the constant value. The heat of hydration during curing of the mixture is measured no significantly. It also shows that temperature characteristics of the mixture is similar to that of soil. Since this mixture is mixed with soil and is able to improve engineering problems in pavement due to temperature, this mixture is expected to use effectively in the environment-oriented pavement for light traffic.
