From november, 1985 to May, 1993, 222 arteriovenous fistulae were made in 201 patients with chronic renal failure. Among them, a total of 183 arteriovenous fistulae in 173 patients were reviewed to evaluate the factors influencing patency rate of the vascular access. The results were revealed as follows: There were 102 men and 71 women,aged 10 to 76 years [mean = 45.7 years]. Sixteen patients of them had previous shunts. The procedures included establishment of 214 radiocephalic or brachioocephalic fistulae, 203 side to end, 9 side to side, 2 end to end, 2 autologous saphenous vein grafts, 6 Gore-Tex grafts. There were 28 early shunt failures[12%] due to use of 23 inadequate veins and 5 thrombosis.There were 32 late complications[14%]; 19 thrombosis, 4 aneurysm, 4 venous hypertension, 3 steal syndrome, 2 infections. There were 32 diabetic patients [17 %]. No significant differences in graft patency were noted between diabetic and nondiabetic individuals. There were no significant difference in graft patency between male and female. Overall shunt patency in 183 cases with chronic renal failure was 96% at I month, 95% at 3 months, 93% at I year, 91% at 2 years, 84% at 3 years, 56% at 5years.This Study showed that early postoperative thrombosis and diabetic vasculopathy were most causes of the vascular access failure and suggested that prevention of thrombi and well control of diabetes mellitus were most important to enhance patency rates of the vascular access.

This study analyzed a change trend of ambient temperature over the last sixty years in the largest industrial city in Korea, Ulsan. Linear warming rates in Ulsan over the last 25 (1985 to 2009), 40 (1970 to 2009), and 60 (1950 to 2009) years were 0.0507, 0.0416, and $0.0277^{\circ}C/yr$, respectively. The annual average temperature (AAT) and the annual average of the daily lowest temperature (AADLT) in Ulsan increased 1.3 and $2.9^{\circ}C$, respectively, over the last fifty years (1960 to 2009). The increasing slopes of the AAT and AADLT over the fifty years in Ulsan were higher or much higher than those in neighboring cities and on a global scale. In the comparison analysis of daily average temperature over the most recent ten years, the highest ($15.9^{\circ}C$) was observed in the industrial area followed by the downtown, coastal, suburban, and rural areas with 14.6, 14.5, 14.0, and $12.8^{\circ}C$, respectively. The number of cold days less than $5.0^{\circ}C$ decreased, while the number of hot days higher than $20.0^{\circ}C$ increased. The decreasing slopes in the cold days in lower latitude cities were steeper than those in higher latitude cities in Korea.

This study examined the changes in the service mix of Korean hospitals in 6 metropolitan cities between 2003 and 2005, and assessed whether the sample hospitals exhibit consistent trend or chance variation in multiple years. Three measures of hospital service mix, focusing on the specialization of services, were applied: information theory index, internal Herfindahl index, and number of distinct diagnosis-related groups (DRGs) treated. National Health Insurance claims were used to calculate the indexes. Specialization indexes were calculated in each year, and then examined to identify the pattern over time. Kappa analysis was applied to assess the agreements of specialization score between two years after hospitals were categorized into 4 groups with quartiles. Kappa score showed that the service mix of hospitals were changed during the study years. Specialization scores were increased given the market structure for three years. Hospitals which showed higher or lower specialization scores than the average of the scores consistently classified into the same group. Specialization indexes showed relatively consistent pattern over 3 years, and such consistencies were evident for hospitals regardless of the specialization status. Policy makers can identify the degree of specialization with the indexes, and it could provide a picture of how hospital services were mixed and changed over time.

Patients over 15 years of age who have undergone a surgical correction of a congenital cardiac malformation during period of January 1958 through January 1986 have been reviewed. During this period there were 3957 congenital cardiac lesions consisting of 2712 acyanotic and 1245 cyanotic cases. Among them, a total of 725 adults [18.3%] with a variety of congenital heart lesions, 548 acyanotic group and 177 cyanotic group were operated on. 372 patients were male and 252 patients were female. There were 280 patients under 20 years of age, 206 between 20-24 years, 102 between 25-29 years, 48 between 30-34 and 89 over 35 years. The most common defects were atrial septal defect which accounted for 207 cases [28.6%] and other common anomalies were VSD [140 cases, 19.3%], TOF [136 cases, 18.6%], PDA [120 cases, 16.6%] and PS [33 cases, 4.6%] in order of incidence. Overall operative mortality for this series was 3.6% [1.8% of a cyanotic group and 9.0% of cyanotic group] compared with 2.8% of total cases of congenital heart disease [acyanotic group 1.1% and cyanotic group 6.5%]. This reviewed series reveals the incidence of operable congenital heart defects appearing in any adult life and demonstrates that surgical repair can be accomplished with a satisfactory low mortality rate.

Purpose: Based on Anderson's model of health service utilization, we investigated the factors that affect the influenza vaccination status in Korean adults aged 50-64 years, who live alone. Methods: Data of 194 Korean adults aged 50-64 years, who live alone were obtained from the Korea National Health and Nutrition Examination Survey 7th Edition (2016-2018). Descriptive statistics and a multiple logistic regression model were used for statistical analysis. Results: The influenza vaccination rate in the study population was 39.3%. Educational status and health behaviors such as smoking habits and regular medical check-up were associated with the influenza vaccination rate in Korean adults aged 50-64 years, who live alone. Multiple logistic regression analysis showed that educational level lower than middle school graduation (odds ratio [OR] 2.02), non-smoking status (OR 1.98), and lack of regular medical check-up (OR 0.62) were significantly associated with the influenza vaccination rate in Korean adults aged 50-64 years, who live alone. Conclusion: The influenza vaccination rate in Korean adults aged 50-64 years, who live alone, is relatively low; therefore, policies should be implemented to improve the influenza vaccination rate in this population. Influenza vaccination in single households was affected by health promotion activities; therefore, interventions are warranted to encourage overall health promotion activities.

The present study conducted a stem analysis to trace growth information of Japanese larch (Larix kaempferi) and predict the future changes in growth volume. For this purpose, six L. kaempferi trees over 47 years old were cut at 1-2 m intervals from a height of 0.2 m, and circular plates of 5 cm thickness were collected for stem analysis. The analysis indicated that approximately 1-8 years are required to grow up to chest height. The annual height and diameter growth increased rapidly until the trees are 15 years old and gradually decreased after 20 years. The volume of 30-year-old trees in Oegam-ri forests, which were well-managed after artificial reforestation, was 0.4837 m³, whereas that in unmanaged Singi-ri forests was 0.1956 m³. Although the volume of individual trees differed greatly depending on the forest management status, it was found that the volume increased by 1.67-1.76, 2.49, and 3.49 times at 40, 50, and 60 years age, respectively, compared to the legal harvesting age 30. Therefore, factors such as the carbon dioxide reduction effect, forest management benefits, and the condition of trees at the site should be considered before harvesting trees.

Objectives: This study was carried out to investigate bone mineral density (BMD), blood pressure, age and biochemical index and nutrient intakes, and to analyze the relationship between BMD, blood pressure, biochemical index, nutrient intakes of Korean women. Methods: The study subjects were 499 women with a age range of 30-79 years living in Seoul and Kyunggi area who participated in 2011 KNHANES. The study subjects were divided into 5 age groups : 30 years (145), 40 years (110), 50 years (102), 60 years (85) and 70 years (57), and 3 BMD groups: normal 258 (50.4%), osteopenia 163 (32.9%) and osteoporosis 78 (16.7%). Results: The average waist circumference, BMI and body fat increased with age, but fat free mass decreased with age. Average BMD and T-score was decreased from 0.84, $0.74g/cm^2$ in 30 years to 0.05, $-1.05g/cm^2$ in 70 years. The rates of osteopenia and osteoporosis increased significantly 22% in 30~40 years, 47% in 50 years and 56% in 60~70 years. Systolic blood pressure and cholesterol were significantly increased with age. The rates of hypertension was significantly increased 2.1% in 30 years, 30.4% in 50 years 89.5% in 70 years. Average nutrient intakes such as protein, calcium, iron, vitamin A and C were significantly decreased with age. There were significant negative correlations between age and calcium, systolic blood pressure, triglyceride. Conclusions: In this study, we found the risk of osteoporosis and hypertension were significantly increase with over 50 years age. Calcium and protein intake decreased with age. Therefore, in order to prevent osteoporosis and hypertension, adult women need to be educated regarding the importance of protein, calcium and other nutrients in their diet.
