Background : Though acute respiratory distress(ARDS) often occurs in the early stage of severe acute pancreatitis and significantly contributed to the mortality of the condition, the characteristics of the group who develops ARDS in the patients with acute pancreatitis have not been fully found. The objective of this investigation was to identify predictable factors which distinguish a group who would develop ARDS in the patients with acute pancreatitis. Method : A retrospective analysis of 94 cases in 86 patients who were admitted the Medical Intensive Care Unit with acute pancreatitis was done. ARDS were developed in 13 cases among them (13.8%). The possible clinical factors related to the development were analyzed using univariate analysis and $x^2$-test. Results : The risk of ARDS development was increased in the patients with abonormal findings of chest X-ray at admission compared to the patients with normal chest X-ray (p<0.05). The risk was also increased according to the sevecrity index score in abdominal computed tomography at the time of admission (p<0.05). The higher APACHE III score of the first day of admission, the more risk increment of ARDS development was observed (p<0.01). Patients with more than one points of Murray's lung injury score showed higher risk of ARDS compared to the patients with 0 points of that. The patients with sepsis and the patients with more than three organ dysfunction at admission had 3.5 times and 23.3 times higher risk of the development of ARDS compared to the patients without sepsis and without organ failure in each (p<0.05, p<0.01). Conclusion : The risk of ARDS development would be higher in the acute pancreatitis patients with abnormal chest X-ray, higher CT severity index, higher APACHE III or Murray's lung injury score, accompanying sepsis, and more than three organ failure at admission.

Objective : Stroke is the second major cause of death in Korea. It is known that the survival and ultimate outcome in stroke depend on various factors, so it is not easy to predict unexpected death in stroke. This study was performed in order to find predicting factors of unexpected death in stroke. Methods : A retrospective study was accomplished by reviewing 21 medical records of stroke patients who expired in the ward of Kyung Hee Oriental Medical Center from January 1998 to December 2001. Data analyzed Were physical examination, laboratory findings, clinical charts and APACH III scoring system. Results : I. The number of unexpected deaths at the ward of Kyung Hee Oriental Medical Center from January in 1998 to December in 2001 were 21 patients (0.1%). 2. Major risk factors of unexpected death were age (${\geq}60$), high blood pressure on 1st admission day and acute stage (${\leq}30{\;}days$). 3. The most frequent time of unexpected death was from 6 a.m. to noon. 4. Major cause of unexpected death was recurrence of stroke (40%). 5. APACH III scores of 75% of unexpected death patients were over 30 points. 6. Clinical change of symptoms 3 or 4 days before the unexpected death were dyspnea, change of urination and defecation. Conclusion; This mortality study suggests that old age, high blood pressure on 1st admission day, acute stage, and high APACH III score are the major predictors of unexpected death in stroke patients and that intensive medical attention is necessary to reach a better outcome.

This study aims to investigate the effect of college choice factors on withdrawal intention of first-year undergraduates in STEM majors. The data for this study were collected from a national sample of 4-year institutions that participated in Collegiate Longitudinal Study funded by the National Research Foundation of Korea during 2013-2014. The data included 1,484 students in STEM majors from 30 institutions, and this study used bivariate and multivariate analytic methods to answer the research questions. This study found that while the internal dimensions of college choice showed a negative effect on the intention to dropout, external dimensions of college choice such as college environment, financial accessibility, admission possibility had a positive effect on the intention. The findings indicate that it is necessary to pay attention to college choice for enrollment management to prevent first-year undergraduates in STEM majors from dropping out.

Purpose: This retrospective study was done to evaluate the status of nosocomial urinary tract infections and to determine the risk factors and transmission route of causal IRPA through molecular epidemiology. Method: Two hundred ninety-nine of 423 patients admitted to the internal medicine and surgery ICU at a university hospital incity B had a positiveurine culture. Twelve of the 299 patients who had a urinary tract infection had IRPA strains. The data was collected from November 1, 2004 to January 31, 2005. The following results were obtained after the data was analyzed using percentile and UPGMA. Result: The rate of nosocomial urinary tract infections in the ICU was 10.8%. Therewere 16.8 cases of infection based on the period of hospitalization. There were 16.9 cases of infection based on the use of a foley catheter. The rate of nosocomial urinary tract infection in the ICU and urinary tract infections related to IRPA were higher in patients with the following characteristics: men, old age, admission through the emergency room, longer than seven days admission, severity of admitting causes, disturbance of consciousness, hydration less than 300cc in 24hours, a long course of antibiotics, a long period of foley catheterization and perineal care. Most of the microorganisms that caused the urinary tract infection were gram negative bacilli, among which P. aeruginosa was found in 70 patients (18.5%) and IRPA in 12 (4.0%). Among the 12 IRPA strains that were tested with PFGE, eight showed a dice coefficient higher than 80%, suggesting a genetic relationship. They were related with the period of hospitalization in the same ICU. These patients all received direct care for a urinary tract infection. Conclusion: Through these results, IRPA can be consideredas a contributing factors to urinary tract infections thus, active preventative measures are needed by the medical staff.

The purpose of this study is to estimate the population requiring nursing home services among elderly people in Korea. This study identifies the need of nursing home services determined by health care professionals and estimates the proportion of elderly people requiring nursing home service according to the admission criteria. Surveys were conducted on health care professionals including medical doctors, home care nurses, and nurse practitioners. They were asked to assess nursing home need based on four content areas: Physical function (Activities of Daily Living), chronic disease, Physical symptoms (incontinence), mobility, eating, and sensory function. Based on the professionally determined need criteria the proportion of elderly people requiring nursing home services was estimated using secondary data from the 1994 Survey on the Living Status of the Korean Elderly. The number of study subjects to estimate nursing home need who were 60 and older totaled 2,058. The most important factor contributing to the admission eligibility criteria was the elderly living alone. Other factors related were the elderly being unable or having difficulty carrying out activities, and having insufficient help from other our activities, and having insufficient help from other members of the household. Using only physical function, the proportion of elderly people requiring nursing home was $8{\sim}9%$. When only chronic disease was used, proportions varied widely; for the doctor's group, the proportion was over 30%. Using all areas, the proportions of elderly people requiring nursing home were between 13% and 38%. The estimate using chronic disease and physical function was similar to the on using all areas.

Objectives: To develop a model that predicts a death probability of acute myocardial infarction(AMI) patient, and to evaluate a performance of hospital services using the developed model. Methods: Medical records of 861 AMI patients in 7 general hospitals during 1996 and 1997 were reviewed by two trained nurses. Variables studied were risk factors which were measured in terms of severity measures. A risk model was developed by using the logistic regression, and its performance was evaluated using cross-validation and bootstrap techniques. The statistical prediction capability of the model was assessed by using c-statistic, $R^2$ as well as Hosmer-Lemeshow statistic. The model performance was also evaluated using severity-adjusted mortalities of hospitals. Results: Variables included in the model building are age, sex, ejection fraction, systolic BP, congestive heart failure at admission, cardiac arrest, EKG ischemia, arrhythmia, left anterior descending artery occlusion, verbal response within 48 hours after admission, acute neurological change within 48 hours after admission, and 3 interaction terms. The c statistics and $R^2$ were 0.887 and 0.2676. The Hosmer-Lemeshow statistic was 6.3355 (p-value=0.6067). Among 7 hospitals evaluated by the model, two hospitals showed significantly higher mortality rates, while other two hospitals had significantly lower mortality rates, than the average mortality rate of all hospitals. The remaining hospitals did not show any significant difference. Conclusion: The comparison of the qualities of hospital service using risk-adjusted mortality rates indicated significant difference among them. We therefore conclude that risk-adjusted mortality rate of AMI patients can be used as an indicator for evaluating hospital performance in Korea.

Purpose: The purpose of this study was to investigate the level of nausea, vomiting, anorexia, fatigue and quality of life as well as to determine the relationship between those variables and identify the influencing factors on fatigue and quality of life in stomach cancer patients receiving adjuvant chemotherapy. Method: Subjects were 94 stomach cancer patients undergoing postoperational chemotherapy in a general hospital in Seoul. Nausea and vomiting were measured with Rhodes et al(1984) and anorexia with one 5-point item. Fatigue was measured using Lee's tool(1999) except open questions. The tool for quality of life was modified based on the Quality of Life Index by Padilla et al(1983). Result: Subjects reported low level of fatigue(mean=3.86, range=0-10) compared with the results of previous researches and moderate quality of life(mean=2.64, range=1-4). Fatigue was positively correlated with nausea, vomiting and anorexia(r=.21 ~ .55, p<.05). Quality of life was negatively correlated with nausea, vomiting, anorexia(r= -.24 ~ -.45, p<.05) and fatigue (r=-.61, p<.01). Multiple regression analysis revealed that activity level, vomiting before admission, anorexia during chemotherapy and age explained 52.8% of the variance in fatigue. Fatigue, anorexia before admission, age and sex explained 50.5% of the variance in quality of life. Fatigue and quality of life were not influenced by the stage of disease, nor weight change. Conclusion: These results may contribute to a better understanding of how much the side effects of anticancer drugs can affect fatigue and quality of life in cancer patients undergoing chemotherapy. Also it is the remarkable fact that symptoms remaining after discharge such as vomiting or anorexia continued until re-admission, contributing to patients fatigue and lowered their quality of life.

Purpose: To provide basic data and to identify the risk of pressure ulcers among neurological patients in ICU. Method: The participants in the study were on 78 neurological patients in the ICU of 3 hospitals. Data were collected every other day from 24 hours after admission, for up to 40 days or until discharge. The total period of data collection was 3 months. The risk assessment scales used for pressure ulcer were the Cubbin & Jackson(1991) scale and the National Pressure Ulcer Advisory Panel(1989) skin assessment tool. Results: There was a significant relationship between having a pressure ulcers and weight, skin condition, mental status, respiration, hygiene and hemodynamic status compared to not having a pressure ulcer. The incidence rate of the pressure ulcer was 28.2%(n=22). Of these patients the mean number of hospitalization days until pressure ulcer development was 5.2 days. The most common pressure ulcer site was the coccyx(39.3%). Based on a cut-off point of 24, 9 patients with risk scores <24 on admission also showed risk score for development of pressure ulcers, 10 patients with pressure ulcer scores ${\geq}24$ were older, hospitalized for a longer time, had low serum albumin, low hemoglobin, diabetes mellitus and surgery. Conclusion: In order to make the Cubbin & Jackson risk assessment scales more useful, there is a need to determine the reliability of the upper cut-off point 24. The result also showed a need to assess other risk factors and for early identification of at-risk patients in order to provide preventive care from admission to discharge.

In order to analyze possible effects of senior hospital selection factors and service satisfaction on senior hospital patients' revisit of senior hospital, this study surveyed guardians of total 204 patients hospitalized in major 4 senior hospitals in Busan. As a result, this study came to the following conclusions: First, it was found that guardians considered appropriateness of medical treatment cost as the biggest factor of choice, which was followed by kindness of doctor and hospital employees, locational accessibility (traffic convenience), and doctor's medical capacity. Second, the factor analysis about patients' satisfaction showed that the influential factors consisted of satisfaction at medical staffs, satisfaction at nursing and care, and satisfaction at facilities. Third, there was not significant difference in the overall impression of hospital and the intention of revisit depending upon sociological variables. Fourth, satisfaction at nursing and care and satisfaction at facilities had significant effects on better satisfaction at overall impression of hospital, and it was noted that the shorter admission period and the less complaint led to the higher intention of revisit. Therefore, it is necessary to improve satisfaction at medical staffs, nursing and care, and facilities rather than patients' own sociological characteristics.
