The purpose of this study was to investigate and compare job satisfaction, job stress, and nursing task performance for nursing and nursing integrated service wards and general ward nurses to provide basic data for efficient nursing manpower management in nursing and nursing integrated service wards. For comparative research. The subjects were 136 nurses in the nursing and nursing integrated service ward and general ward nurses at a general hospital in D metropolitan area. There was no significant difference between the groups in the job satisfaction, job stress, and nursing task performance of the nursing and nursing integrated service ward nurses and general ward nurses. The performance was high. Factors influencing the performance of nursing tasks were job satisfaction and job stress, with 20.6% of nurses in nursing and nursing integrated service wards and 47.5% of nurses in general wards. Therefore, there is a need for support to improve the ability to perform nursing tasks that can increase job satisfaction and maintain job stress.

This research was performed to figure out the optimal mixing ratio of food- to livestock wastewater for the best degradation of organic matter in the anaerobic digestion. The presence of various microorganisms, such as Escherichia coli and Staphylococcus aureus, was also investigated in both wastewater in this process. Enteric bacteria were only found in livestock wastewater, whereas pathogenic bacteria like S. aureus were detected in both wastewater. The optimal mixing ratio of food- to livestock wastewater for the best mineralization was found to fifty to fifty, with reduction ratios of $BOD_5$, CODcr SS as 23.2%, 24.7%, 19.7%, respectively. Hygiene of the digested sludge was also analyzed by counting the number of total colonies and various pathogens. Enterobacteriaceae including E. coli were barely detected in 10 days after reaction. Meanwhile, S. aureus was gradually reduced during reaction, even showing 1,000~5,000 CFU/mL in final days.

We evaluated the possible clinical application of Non HDL-cholesterol and triglyceride to HDL-cholesterol ratio as a metabolic syndrome predictor for the elderly in Korea. 1,543 elderly persons aged 65 years or older who visited the health examination center of Gyeonggi Regional General Hospital from January 2015 to December 2017 and had a health checkup were enrolled in this study. Metabolic syndrome was diagnosed based on the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI) standards. Abdominal obesity was assessed by the Asia-Pacific standards presented at the World Health Organization (WHO) West Pacific Region. Non-HDL-cholesterol was calculated as the difference between total cholesterol and HDL-cholesterol. The metabolic syndrome predictive power was higher for triglyceride to HDL-cholesterol ratio than for Non HDL-cholesterol. After correcting for related factors, triglyceride to HDL-cholesterol ratio was higher in the $4^{th}$ quartile, which had a higher risk of developing metabolic syndrome, than in the $1^{st}$ quartile. The optimal cutoff value for the triglyceride to HDL-cholesterol ratio that predicts the onset of metabolic syndrome was 2.8. triglyceride to HDL-cholesterol ratio can be a simple and practical indicator of the risk of metabolic syndrome.

Transformation system of rolC gene, dwarf gene in Lycium chinenese Mill. established by using system. Pin-punctured leaves induced numerous adventious buds in abaxial side when cultured on 3/2 MS medium containing 2.0 mg/L zeatin. Survival rate and shoot regeneration frequency of leaf explants decreased as kanamycin sulfate level increased. Shoot buds were not regenerated on 3/2 MS medium containing 10 mg/L kanamycin sulfate and 2.0 mg/L zeaein. Of the level tested, 10 mg/L of kanamycin sulfate was optimum in selection of kanamycin sulfate resistant plant. Co-culture time of bacteria and leaf explants was affected at the frequency of shoot regeneration and survival of leaf explants. Leaf explants co-cultivated during above 48hr severely decreased survival rate and shooting rate. Best result on survival rate and shooting rate were obtained when exposed for 24 h. 80 explants of 105 leaf explants survived on 3/2 MS medium containing 2.0 mg/L zeatin and 10 mg/L kanamycin sulfate, and 15 shoots was regenerated on the same medium. To select kanamycin sulfate resistant plant, regenerate as cultured on 3/2 MS medium containing 10 mg/L kanamycin sulfate, and obtained 5 kanamycin resistant plants. Southern blot analysis conformed that the rolC gene was incorporated into the genomic DNA of kanamycin resistant plants.

Purpose: The aim of this study was to evaluate the clinical characteristics, endoscopic findings and risk factors related to the upper gastrointestinal bleeding (UGIB) seen in full-term infants. Methods: A clinical analysis for 9 cases with UGIB confirmed by endoscopy was carried out retrospectively. Patients were admitted to the Department of Pediatrics, Eulji Hospital, from January to December 2003. Results: UGIB from gastric or duodenal mucosal lesions has been seen in 0.13% in newborns infants. All patients were full-term AGA neonates without asphyxic findings at birth. Hematemesis, melena or recurrent vomiting developed within $4.4{\pm}3.8days$ after birth. Vital sign and laboratory test was normal on admission. Endoscopic findings showed hemorrhagic gastritis in 6 cases and peptic ulcers in 3 cases. All patients were successfully managed by medical treatment for $18.6{\pm}5.0days$. On treatment, clinical symptoms improved within $0.9{\pm}0.3days$. Follow-up endoscopy was not performed because there was no recurrence of symptoms in all patients. Case mothers had no history of gastritis, ulcer or anti-ulcer medications before and during pregnancy. Conclusion: If the healthy full-term infants express UGIB within a few days after birth, it is necessary to take careful history of family, mother and delivery process and to practice endoscopy for mucosal lesions of the patients. A follow-up endoscopy dose not seem to be necessary if the infant is clinically well.

Background: Extra-anatomic bypass was performed in the patient who could not use anatomic bypass due to many causes. The purpose of this study is to evaluate the efficacy of extra-anatomic bypass surgery. Material and Method: We reviewed 31 patients who underwent extra-anatomic bypass surgery at Pusan national university hospital. We analysed the combined diseases, etiologic diseases, symptoms, patency rate and the factors affecting patency rate retrospectively. Result: There were 26 cases of femoro-femoral bypass and 5 cases of axillo-bifemoral bypass among 31 patients. The mean age was 70.23 years. Combined disease were hypertension, hyperlipidemia, and ischemic heart disease in order of frequency. The indications for surgery were disabled claudication, tissue necrosis, rest pain, and a cute ischemia. We analysed the ages, smoking history, hypertension, ischemic heart disease, severity of limb ischemia, and hyperlipidemia as factors affecting patency rate. We could not find any statistical differences between these factors. The primary graft patency rates were $73.65\%$ one year, $73.65\%$ two year, and $65.46\%$ three year respectively according to the Kaplan-Meier method. Conclusion: Nevertheless extra-anatomic bypass has a relatively low patency rate, it has good merits that is less dangerous, simple and easy re-do surgery compared to anatomic bypass. We think that extra-anatomic bypass is one of the good treatment modalities for the high risk vascular patients.

Korea has made a rapid economic development since the last three decades. This has helped Korea narrow the gap in health service differences in resource availability and in quality of care. However urban and rural differentials are still remarkable. This study has maintained that health status of rural residents is inferior to that of urban dwellers. Therefore, this study was carried out to develop policy measures for improving health services in rural areas. In order to achieve the objective of this study the authors collaborated closely and made field visits, interviews and conducted an extensive literature review regarding rural health services. The following policy options are recommended as a summary ; First, the quality of rural health personnel is a single most important factor influencing the level of rural health services. An innovative program for public health doctors to the internship and/or residency training program such as specialty board program of family medicine. Second, dissatisfaction regarding employment of public health doctors is problematic. More rational employment and deployment programs are needed to meet their personal desire. One way to do this is to make it wide open and competitive. Third this study shows how to increase physician productivity in the rural public health sector. Incentive system needs to be elaborated for the career development of rural health workers. University linked job opportunity as clinical professor is an example. Fourth, without straightening the function of health centers and subcenters, the future of rural health services is doomed to failure. Straightening primary health care is one way to enrich the program of public health facilities and reactivating the operation of health center/hospital is another. A close linkage of public facilities with private hospitals is a minimum requirement for the operation of health delivery system within a health district. Fifth, some measures are urgently required to enhance hospital services in medically underserved areas. Financial subsidy, tax exemption, long-term public loans and higher priority of health manpower deployment are some of them. Sixth, new health programs should be in tiated to meet changing needs of peoples in rural areas. Home health care program, hospice program, nursing home, residential program for the elderly are recommended.

Due to population aging and westernized lifestyle, ischemic heart diseases are increasing, and Korea has one of the highest lengths of stay for ischemic heart diseases. Since the increase in the length of stay is a major cause of the increase in medical expenses, it is necessary to prepare a plan to manage the length of stay. Accordingly, this study was conducted to identify the factors influencing the length of stay of ischemic heart disease, and provide the elementary resources necessary for the management of the length of stay. The study subjects were 566 ischemic heart disease patients of a tertiary hospital. As the result of the study, first, the number of inpatients with chest pain as the chief complaint was the largest. Second, the average length of stay was 4.89 days, and the length of stay varied depending on the type of ischemic heart disease. Third, the age of over 75 years, diabetes, and dyspnea were the factors increasing the length of stay. Therefore, for management of adequate length of stay for ischemic heart disease, it is important to prevent the progression of illness through blood sugar control for ischemic heart disease patients with diabetes. Also, it is necessary to prepare a system where patients can visit hospitals as fast as possible if they have any symptoms.

Between December 1979 and September 1989, 23 patients with craniopharyngioma who underwent surgery and postoperative radiation therapy were retrospectively evaluated to assess the efficacy of this management at the Department of Therapeutic Radiology, Seoul National University Hospital. Total removal of tumor was attempted in all patients. Of these, surgeons tried total removal in eight patients, but revealed residual mass by postoperative CT, and partial removal was done in 15 patients. The morphology of tumor on the operative finding was grouped into three types: cystic 13 ($57{\%}$), solid 4 ($17{\%}$), and mixed 6 ($26{\%}$). Cystic type was predominant in$\leq$20 years old group. Actuarial overall survival rates at 5 and 10 years were $95{\%}$ and $81{\%}$ respectively and actuarial tumor control rates were $74{\%}$ and $50{\%}$. Surgical extent was not related to the survival rates (p=0.41). Pediatric and adolescent patients (age of$\leq$20 years) had a trend of better survival than that of adult patients (p=0.10). The results indicated that limited surgical excision followed by radiation therapy is recommended when total excision is not possible.
