Home Health Care is one part of the total health care system. It includes health care services that link the hospital to the community. While it is important for early discharge patients, home care is also important for people with chronic illnesses or handicapping conditions. In 1989 the Korean government passed a law that opened the way for formal development of home health care services beginning with education programs to certify nurses for home care, and then demonstration home care services. Part of the mandate of the demonstration projects was evaluation of home care services. This study was done in order to provide basic data that would contribute to the development of records that could be used for evaluation through a retrospective audit and to examine the care that had been given in Home Care at Wonju Christian Hospital over a twenty year period from 1974 to 1994. The purposes of the study were : to identify to characteristics of the clients who had received home care, to identify the reasons for client referrals, to identify the nursing problems of these clients, to identify the nursing care provided to these clients, and to identify differences in these areas over the twenty year period. The study was a descriptive study involving a retrospective audit of the client records. Demographic data on all clients were included : 4,171 clients from 2,564 families. Data on referrals, nursing diagnosis and nursing interventions were from even numbered records which had a patient problem list included in the record, 2,801 clients, Frequencies and ANOVA were used in the analysis. The results of the study showed that the majority of the clients were from Wonju city /county. There were more women than men related to the high number of postpartum clients(1,300). The high number of postparttum clients and newborns was also evident in the age distribution. An the number of maternal-child clients decreased over the 20 years, the mean age of the clients increased significantly. Other factors also contributed to this change ; as increasing number of clients with brain injuries or with cancer, and fewer children with burns, osteomyelitis and tuberculosis. There was a decrease in the mean number of visits and mean length of coverage, reflecting a movement towards a short term acute care model. The number of new clents dropped sharply after 1985. The reasons for this are : the development of other treatment alternatives for clients, the establishment of an active wellbaby clinic, many more options plus a decreasing number of new cases of Hansen's Disase, and insurance that allows people with burns to be kept in hospital until skin grafts are healed. Socioeconomic changes have resulted in an increase in the number of cases of cancer, stroke, head injuries following car accidents, and of diabetes. Of the 2,801 client records, 2,541(60.9%) contained a written referral but for 1,802 it contained only the medical diagnosis. The number of records with a referral requesting specific nursing care was 739(29.1%). Many family members who were identified as in need of nursing care had no written referral. Analysis of the patient problem list showed that 41.9% of the enteries were nursing diagnoses. Others incuded medical diagnosis, symptoms, and plans. The most frequently used diagnoses were alteration in nutrition, less than body requirements(115 entries), alteration in skin integrity(114), knowledge deficit(111), pain(78), self-care deficit(66), and alteration in pattern of urinary elimination(50). These are reflected in the NANDA categories for which the highest number of diagnosis was in the Exchanging pattern(446), followed by Moving(178), Feeling(136) and Knowing (115). Analysis of the frequency of interventions showed that exercise and teaching about exercise was the most frequent intervention, followed by teaching concering the need for follow-up care, checking vital signs, managing nutritional problems, managing catheters, giving emotional support, changing dressings, teaching about medication, teaching (subject not specified), teaching about diet, IM and IV medications or fluid, and skin care, in that order. Recommendations included: development of a record that would allow for efficient recording of frequently used nursing diagnoses and nursing interventions: expansion of the catchment area for Home Care at Wonju Christian Hospital ; expansion of the service to provide complication prevention, rehabilitation services, and support to increase the health maintenance /health promotion of the people being served as well as providing client dentered care ; and development of a clinical record that will allow efficient data collection from records, even though the recording is done by a variety of health care providers.

Brain perfusion CT scanning is often employed usefully in clinical conditions as it accurately and promptly provides information about the perfusion state of patients having acute ischemic stroke with a lot of time constraints and allows them to receive proper treatment. Despite those strengths of it, it also has a serious weakness that Lens may be exposed to a lot of dose of radiation in it. In this study, as a way to reduce the dose of radiation to Lens in brain perfusion CT scanning, this researcher conducted an experiment with Bismuth shielding and change of patients' position. TLD (TLD-100) was placed on both lens using the phantom (PBU-50), and then, in total 4 positions, parallel to IOML, parallel to IOML (Bismuth shielding), parallel to SOML, and parallel to SOML (Bismuth shielding), brain perfusion scanning was done 5 times for each position, and dose to Lens were measured. Also, to examine how the picture quality changed in different positions, 4 areas of interest were designated in 4 spots, and then, CT number and noise changes were measured and compared. According to the results of conducting one-way ANOVA on the doses measured, as the significance probability was found to be 0.000, so there was difference found in the doses of radiation to crystalline lenses. According to the results of Duncan's post-hoc test, with the scanning of being parallel to IOML as the reference, the reduction of 89.16% and 89.66% was observed in the scanning of being parallel to SOML and that of being parallel to SOML (Bismuth shielding) respectively, so the doses to Lens reduced significantly. Next, in the scanning of being parallel to IOML (Bismuth shielding), the reduction of 37.12% was found. According to the results, reduction in the doses of radiation was found the most significantly both in the scanning of being parallel to SOML and that of being parallel to SOML (Bismuth shielding). With the limit of the equivalent dose to Lens as the reference, this researcher conducted comparison with the dose to occupational exposure and dose to Public exposure in the scanning of being parallel to IOML and found 39.47% and 394.73% respectively; however in the scanning of being parallel to SOML (Bismuth shielding), considerable reduction was found as 4.08% and 40.8% respectively. According to the results of evaluation on picture quality, every image was found to meet the evaluative standards of phantom scanning in terms of the measurement of CT numbers and noise. In conclusion, it would be the most useful way to reduce the dose of radiation to Lens to use shields in brain perfusion CT scanning and adjust patients' position so that their lens will not be in the field of radiation.

Purpose: increased uptake of wrist and hand joints in three phase bone scintigraphy (TPBS) have been used in the detection of reflex sympathetic dystrophy syndrome (RSDS). TPBS frequently shows increased shoulder uptake in the hemiplegic RSDS patients. We investigated the significance of the shoulder uptake in the detection of these patients. Materials and Methods: Twenty three patients who had hemiplegia due to brain stroke and diagnosed as RSD were enrolled in this study (M:F=16:7, R:L=11:12). The mean age was $63{\pm}10$ yrs. Ter normal volunteer (mean age: $60{\pm}5$, M:F=1:9) data was used as control group. TPBS was performed $59{\pm}32$ days after stoke (acute stage). We obtained the count ratios of bilateral hands by drawing a region of interest (ROI) in three phase images and compared to the count ratios of shoulders in the delayed image. Hand ROI included an ipsilateral wrist. Sensitivity of detecting the affected limb was defined using the right/left count ratio of normal control. Results: Sensitivities using count ratios of hand blood flow, blood pool and delayed image were 45%, 76% and 78%, respectively. Sensitivity of shoulder count ratio was 74%. Log of right/left counts of hand delayed image and that of shoulder delayed image were correlated well with statistical significance (Spearman's R=0.824, p<0.001). Conclusion: Shoulder uptake showed good correlation with hand uptake in the delayed image of TPBS. Shoulder uptake maybe helpful in the diagnosis of reflex sympathetic dystrophy syndrome in patients with hemiplegia.

Purpose: Acute symptomatic seizures are caused by structural changes, inflammation or metabolic changes of brain, such as tumor, stroke, meningitis, encephalitis and metabolic disorders. Inherited metabolic disorders that can cause seizures are organic acidopathies, lysosomal storage disorders, peroxisomal disorders and mineral disorders. We have done this study to find out the importance of organic acidopathies causing seizure disorders in Korean childhood and adolescent patients. Method: Retrograde analysis for 1,306 patients with seizure disorders whose clinical informations are available and have done urine organic acid analysis for 5 years period, between Jan. 1st 2007 to Dec. 31th 2011. Statistical analysis was done with Student's t test using SPSS. Result: Out of 1,306 patients, 665 patients (51%) showed abnormalities on urine organic acid analysis. The most frequent disease was mitochondrial respiratory chain disorders (394, 30.1%), followed by mandelic aciduria (127, 9.7%), ketolytic defects (81, 6.2%), 3-hydroxyisobutyric aciduria (19, 1.4%), glutaric aciduria type II (10, 0.8%), ethylmalonic aciduria (4), propionic aciduria (4), methylmalonic aciduria (3), glutaric aciduria type I (3), pyruvate dehydrogenase deficiency (3), pyruvate carboxylase deficiency (3), isovaleric aciduria (2), HMG-CoA lyase deficiency (2), 3-methylcrotonylglycinuria (2), fatty acid oxidation disorders (2), fumaric aciduria (1), citrullinemia (1), CPS deficiency (1), MCAD deficiency (1). Conclusion: On neonatal period, mandelic aciduria due to infection was found relatively frequently. Mitochondrial disorders are most frequent etiologic disease on all age group, followed by ketolytic defects and various organic acidopathies. The number and diversities of organic acidopathies emphasize meticulous evaluation of basic routine laboratory examinations and organic acid analysis with initial sample on every seizure patient.

A survey was made from March 1978 through Feb. 1979 to know infection rate of parasites and incidence of diseases in 1968 cattle of 240 rearing and fattening cattle herds (1746 Korean native cattle, 186 Holstein, 34 Charolais and 2 Hereford) raising in 28 cities and counties of Gyeongbug district. The results obtained are summarized as follows: 1. The rate of nematoda infection was about 49.0% in the examined cattle. These nematodes were identified as Mecistocirrus sp., Oesophagostomum sp., Bunostomum sp., Trichostrongylus spp., Strongyloides sp. and other 3 species. Infection rate of nematoda in fattening and breeding cattle was higher than that in rearing calves, 44.3% of the positive cattle were infected with 2 to 5 species, and incidence of mixed infection was high in fattening cattle. 2. The rate of coccidal infection was 10.9%. Eimeria $z{\ddot{u}}rni$, Eimeria bovis and Eimeria bukidnonensis were mainly found in the examined cattle. The infection rates of cocidia in Holstein, breeding Korean cows, rearing Korean calves and fattening Korean cattle were 27.3%, 15.8%, 11.2% and 9.1%, respectively. 3. The rate of trematoda was 14.6% with Fasciola spp. (11.2%), Eurytrema spp. (2.0%), and Paramphistomum spp. infections (1.4%). Breeding Korean cows, fattening Korean cattle, Holstein and rearing Korean calves indicated 47.4%, 26.4%, 18.2% and 6.3% incidence of trematoda infections, respectively. of trematoda positive cattle, 76.6% were infected with Fasciola spp., 4. The rate of Theileria and Babesia infection was 62.7% in the examined cattle. Of these positive cattle 5.4% were infected with both parasites, 57.3% with Theileria, and 1.3% of rearing Korean calves and 22.6% of Holstein were found to have parasitized erythrocytes over 1.0%. 5. The incidence of diseases in 1968 cattle of 240 herds was 564 cattle (28.7%) of 154 herds (64.2%). of the diseases observed of skin occurred in 354 cattle (18.0%) of 61 herds (25.4%), diseases of respiratory system in 121 cattle (6.1%) of 34 herds (14.2%), diseases of digestive system in 38 cattle (1.9%) of 22 herds (9.2%), diseases of eye in 21 cattle (1.1%) of 13 herds (5.4%), diseases of urogenital system in 8 cattle (0.4%) of 8 herds (3.3%) and the other diseases in 24 cattle (1.2%) of 22 herds (9.2%). 6. Diseases of skin in 1968 cattle of 240 herds werds were observed in the highest incidence. Ringworm was observed in 13.3% of the examined herds, rearing Korean calves and Holstein showed high incidence. Scabies caused by Chorioptes bovis and alopecia localis along with infestation of lice (Damalinia bovis, Linognathus vituli) were observed in fattening Korean cattlein winter. 7. Diseases of respiratory system occurred frequently in rearing Korean cattle and Holstein. In the diseases of digestive system acute indigestion occurred in fattening Korean cittle, enteritis in rearing Korean calves and Holstein, and coccidiosis in rearing Korean calves maninly. 8. Infectious keratoconjunctivitis occurred in a fattening Korean cattle herd, sterility (2.0%) in breeding Korean cows, and theileriosis in Holstein calves were also occurred. In addition, poisoning and heat stroke were observed in several cattle.

Background: The number of elderly patients undergoing coronary artery bypass grafting (CABG) is increasing. Elderly patients are at increased risk for a variety of perioperative complications and mortality. We identified determinants of operative complications and mortality in elderly patients undergoing CABG. Material and Method: Between January 1995 and July 2003, 91 patients older than 75 years underwent isolated CABG at Asan Medical Center. There were 67 men and 24 women with mean age of $77.0\pm2.4$ years. Thirty clinical or hemodynamic variables hypothesized as predictors of operative mortality were evaluated. Result: CABG was performed under emergency conditions in 5 patients. The internal thoracic artery was used in 85 patients and 10 patients received both internal thoracic arteries. The mean number of distal anastomosis was 3.7 per patient. Operative mortality was $3.3\%$. Twenty-two patients had at least one major postoperative complication. Low cardiac output syndrome was the most common complication, followed by reoperation for bleeding, pulmonary dysfunction, perioperative myocardial infarction, stroke, acute renal failure, ventricular arrhythmia, upper gastrointestinal bleeding, infection, and delayed sternal closure. None were the predictors of mortality. Renal failure, peripheral vascular disease, emergency operation, recent myocardial infarction, congestive heart failure, New York Heart Association (HYHA) class III or IV, Canadian Cardiovascular Society (CCS) angina scale III or IV, and low left ventricle ejection fraction below $40\%$ were univariate predictors of overall complications. Actuarial probability of survival was $94.9\%,\;89.8\%,\;and\;83.5\%$ at postoperative 1, 3 and 5 years respectively. During the follow-up period $93.3\%$ of patients were in NYHA class I, or II and $91.1\%$ were free from angina. Conclusion: Although operative complication is increased, CABG can be performed with an acceptable operative mortality and excellent late results in patients older than 75 years.

This study was performed to identify the impact of awareness and educational experiences on cardiopulmonary resuscitation in the ability to execute of cardiopulmonary resuscitation among Korean adults. This study used original data of 2014 Community Health Data Survey. 228,712 participants in this survey were resident in South Korea who is aged 19 or older on July 2014. Participants in this survey were sampled an average of 900 residents(target error ${\pm}3percent$) per community health center of Korea. Data were analyzed by using R 3.1.3 employing chi-squared test, fisher's exact analysis, and logistic regression analysis. Ability to execute CPR was significantly higher in males(3.34 time), higher the education level (1.61 times), the white color occupation (1.14 times), the higher the income level (1.07 times), the higher the education level (0.91 times), non-hypertensive patients (1.12 times), non-diabetic patients (1.16 times), non-dyslipidemic patients (0.86 times), non-stroke patients (0.30 times), CPR education experience group (3.25 times), CPR experience group with manikin-based training (4.30 times), higher subjective health status (1.08 times, 1.16 times) respectively. This study identified that awareness, educational experience, and mannequin-based learning experience of CPR impacted on the ability to execute CPR. Responding to education-related factors could contribute to reducing the rate of out-of-hospital acute cardiac arrest by improving the ability to execute CPR of the general public.

Background: Though clinical practice guidelines (CPGs) for cardiac rehabilitation (CR) are an effective and widely used treatment method worldwide, they are as yet not widely accepted in Korea. Given that cardiovascular disease is the second leading cause of death in Korea, it is urgent that CR programs be developed. In 2008, the Government of Korea implemented CR programs at 11 university hospitals as part of its Regional Cardio-Cerebrovascular Center Project, and 3 additional medical facilities will be added in 2019. In addition, owing to the promotion of CR nationwide and the introduction of CR insurance benefits, 40 medical institutions nationwide have begun CR programs even as a growing number of medical institutions are preparing to offer CR. The purpose of this research was to develop evidence-based CPGs to support CR implementation in Korea. Methods: This study is based on an analysis of CPGs elsewhere in the world, an extensive literature search, a systematic analysis of multiple randomized control trials, and a CPG management, development, and assessment committee comprised of 33 authors-primarily rehabilitation specialists, cardiologists, and thoracic surgeons in 21 university hospitals and 2 general hospitals. Twelve consultants, primarily rehabilitation, sports medicine, and preventive medicine specialists, CPG experts, nurses, physical therapists, clinical nutritionists, and library and information experts participated in the research and development of these CPGs. After the draft guidelines were developed, 3 rounds of public hearings were held with staff members from relevant academic societies and stakeholders, after which the guidelines were further reviewed and modified. Results: CR involves a more cost-effective use of healthcare resources relative to that of general treatments, and the exercise component of CR lowers cardiovascular mortality and readmission rates, regardless of the type of coronary heart disease and type and setting of CR. Conclusion: Individualized CR programs should be considered together with various factors, including differences in heart function and lifestyle, and doing so will boost participation and adherence with the CR program, ultimately meeting the final goals of the program, namely reducing the recurrence of myocardial infarction and mortality rates.

Background: Off-pump coronary artery bypass grafting (OPCAB) shows fewer side effects than cardiopulmonary by. pass, and other benefits include myocardial protection, pulmonary and renal protection, coagulation, inflammation, and cognitive function. We analyzed the clinical results of our cases of OPCAB. Material and Method: From May 1999 to August 2007, OPCAB was performed in 100 patients out of a total of 310 coronary artery bypass surgeries. There were 63 males and 37 females, from 29 to 82 years old, with a mean age of $62{\pm}10$ years. The preoperative diagnoses were unstable angina in 77 cases, stable angina in 16, and acute myocardial infarction in 7. The associated diseases were hypertension in 48 cases, diabetes in 42, chronic renal failure in 10, carotid artery disease in 6, and chronic obstructive pulmonary disease in 5. The preoperative cardiac ejection fraction ranged from 26% to 74% (mean $56.7{\pm}11.6%$). Preoperative angiograms showed three-vessel disease in 47 cases, two-vessel disease in 25, one-vessel disease in 24, and left main disease in 23. The internal thoracic artery was harvested by the pedicled technique through a median sternotomy in 97 cases. The radial artery and greater saphenous vein were harvested in 70 and 45 cases, respectively (endoscopic harvest in 53 and 41 cases, respectively). Result: The mean number of grafts was $2.7{\pm}1.2$ per patient, with grafts sourced from the unilateral internal thoracic artery in 95 (95%) cases, the radial artery in 62, the greater saphenous vein in 39, and the bilateral internal thoracic artery in 2. Sequential anastomoses were performed in 46 cases. The anastomosed vessels were the left anterior descending artery in 97 cases, the obtuse marginal branch in 63, the diagonal branch in 53, the right coronary artery in 30, the intermediate branch in 11, the posterior descending artery in 9 and the posterior lateral branch in 3. The conversion to cardiopulmonary bypass occurred in 4 cases. Graft patency was checked before discharge by coronary angiography or multi-slice coronary CT angiography in 72 cases, with a patency rate of 92.9% (184/198). There was one case of mortality due to sepsis. Postoperative arrhythmias or myocardial in-farctions were not observed. Postoperative complications were a cerebral stroke in 1 case and wound infection in 1. The mean time of respirator care was $20{\pm}35$ hours and the mean duration of stay in the intensive care unit was $68{\pm}47$ hours. The mean amounts of blood transfusion were $4.0{\pm}2.6$ packs/patient. Conclusion: We found good clinical outcomes after OPCAB, and suggest that OPCAB could be used to expand the use of coronary artery bypass grafting.
