Purpose: This study aimed to conduct a job analysis of nurse carecoordinators and to identify the frequency, importance and difficulty of each task of their job. Methods: A committee for developing a curriculum (DACUM) was formed and members of the committee defined nurse care coordinators’ jobs and enumerated the duties, tasks and task elements by applying the DACUM technique. Then nurse care coordinators enrolled in the pilot project evaluated the frequency, importance and difficulty of each task. Results: From the job descriptions of nurse care coordinators, we identified 12 duties and 42 tasks. Each task comprised 1~5 task elements. Among tasks, ‘assess the patient’s general health status’ was carried out most frequently. Nurse care coordinators perceived that ‘check vital signs’ and ‘strengthen patient competence to promote health behaviors’ were more important than all other tasks. The most difficult task was ‘develop professionalism as a nurse care coordinator’. Conclusion The nurse care coordinators' roles developed in this study will serve as the key guidelines for human resource management of care coordinators. Further, job specifications for nurse care coordinators need to be developed, which is necessary for designing education and training programs. We also need to integrate primary health care as an essential component in nursing education.

BACKGROUND: Several factors contribute to differences in Streptococcus pneumoniae serotype distribution. We investigated the serotype distribution and antimicrobial resistance of S. pneumoniae isolated between 2014 and 2016 in Korea. METHODS: We collected a total of 1,855 S. pneumoniae isolates from 44 hospitals between May 2014 and May 2016, and analyzed the serotypes by sequential multiplex PCR. We investigated the distribution of each serotype by patient age, source of the clinical specimen, and antimicrobial resistance pattern. RESULTS: The most common serotypes were 11A (10.1%), followed by 19A (8.8%), 3 (8.5%), 34 (8.1%), 23A (7.3%), and 35B (6.2%). The major invasive serotypes were 3 (12.6%), 19A (7.8%), 34 (7.8%), 10A (6.8%), and 11A (6.8%). Serotypes 10A, 15B, 19A, and 12F were more common in patients ≤5 years old, while serotype 3 was more common in patients ≥65 years old compared with the other age groups. The coverage rates of pneumococcal conjugate vaccine (PCV)7, PCV10, PCV13, and pneumococcal polysaccharide vaccine 23 were 11.8%, 12.12%, 33.3%, and 53.6%, respectively. Of the 1,855 isolates, 857 (46.2%) were multi-drug resistant (MDR), with serotypes 11A and 19A predominant among the MDR strains. The resistance rates against penicillin, cefotaxime, and levofloxacin were 22.8%, 12.5%, and 9.4%, respectively. CONCLUSIONS: There were significant changes in the major S. pneumoniae serotypes in the community. Non-PCV13 serotypes increased in patients ≤5 years old following the introduction of national immunization programs with the 10- and 13-polyvalent vaccines.

Pig pancreas may be a therapeutic resource for human diabetic patients. However, this potential is hindered by a lack of knowledge of the molecular events of pig pancreas development. In this study, the embryonic day 60, neonate and 6-month protein profiles of pig pancreas were ascertained at using two-dimensional gel electrophoresis and matrix assisted laser desorption/ionization-time of flight mass spectrometry. Twenty four proteins were differentially expressed during pig pancreas development. Among them, 12 spots increased and 7 spots decreased according to development. The expression of 5 protein were highest at birth. Expression of digestive enzymes including trypsin, pancreatic triacylglycerol lipase and pancreatic alpha-amylase was elevated in adults, whereas chymotrypsins were highly expressed in neonates. Proteins that were abundantly expressed during gestation were alpha-1-antitrypsin, alpha-fetoprotein and transferrins. Taken together, we found out that several proteins were significantly up- or down- regulated from pig pancreas based on developmental stage. This study will provide basis for understanding development of pig pancreas.

PURPOSE: The purpose of this study was to explore the use of outcome indicators and perception of outcome evaluation of oncology advanced practice nurses (APNs). METHOD: A total of 111 oncology APNs from hospitals which have over 400 beds were surveyed. The participants' use of outcome indicators and perception of outcome evaluation were collected using a questionnaire including 84 outcome indicators for APNs developed by Sung et al. and 13 items on APNs' contribution to the hospitals developed by Kleinpell (2005). Data were analyzed using descriptive statistics, t-test, and chi2 test. RESULT: Twelve items out of 84 outcome indicators were used over 50% of the time and 57 items could be used in the future by the participants. Seven of the 10 top-ranking outcome indicators in use were education related and were also expected to be used frequently in the future. The score for participants' perception of outcome evaluation was average-high, 3.82 out of 5. CONCLUSIONS: The results of the study show that the main outcome indicator for oncology APNs is education related, and thus the use of education related outcome indicators is recommended to make oncology APNs' activities be more visible.

PURPOSE: This study was done to compare the rates of hemolysis and repeated sampling in blood samples obtained by a syringe needle versus a vacuum tube needle. METHODS: A randomized, prospective study was used to evaluate the differences between the two blood sampling methods. The study group consisted of patients seen in the emergency department (ED) for blood sampling to determine electrolyte level. ED patients were randomly assigned to either the syringe group or the vacuum tube group. All blood samples were collected by experienced ED nurses and hemolysis was determined by experienced laboratory technologists. Data were analyzed using Fisher's exact test and binary logistic regression. RESULTS: One hundred forty-five valid samples were collected (74 in the syringe group versus 71 in the vacuum tube group). 5 of 74 (6.8%) blood samples in the syringe group and 8 of 71 (11.3%) in the vacuum tube group hemolyzed. Repeated blood sampling occurred for 2 of 74 (2.7%) and 3 of 71 (4.2%) in each group respectively. There were no significant differences in rates of hemolysis and repeated sampling between two groups (B=1.97, p=.204; B=2.36, p=.345). CONCLUSION: Venipuncture with syringe needles can be recommended for ED nurses to obtain blood samples.

OBJECTIVE: To investigate the correlation between pre-morbid personality and depression scales in patients with stroke. METHOD: The subjects of this study included 45 patients with stroke and their caregivers. We conducted an interview of patients with Beck Depression Inventory (BDI) and also evaluated general characteristic (age, sex, location of lesion, cause of stroke, duration of illness, educational background, history of medication for depression) and functional level. Caregivers were evaluated with Hamilton Rating Scale for Depression (HRSD) for depressive mood, with NEO-PI (Neuroticism, Extraversion and Openness Personality Inventory) for pre-morbid personality. The results of each questionnaire were analyzed in order to investigate their correlation. The results were statistically analyzed with independent t-test, ANOVA, and Pearson correlation test. RESULTS: The HRSD score of the caregivers had a significant correlation with the BDI score (p=0.001) of the patients. The BDI score correlated with Neuroticism (p=0.021) and the HRSD score also correlated with Neuroticism (p=0.015). There were no statistical correlation of depression with sex, age, case of stroke, location of lesion, duration of illness and functional level. CONCLUSION: Among pre-morbid personalities, neuroticism of NEO-PI is the only factor which is significantly correlated with depression scales in stroke patients. Evaluating pre-morbid personality can be helpful in predicting the depressive mood in stroke patients, so we may have early intervention for it.

Abdominal pregnancy, a rare type of ectopic pregnancy is difficult to be suspected at its first presentation. The diagnosis of this rare disease may often be delayed, since early symptoms are usually non-specific. In some cases, delayed diagnosis of abdominal preganacy can be associated with catastrophic hemorrhage secondary to placental separation. A 24-year old woman visited our emergency unit, presenting with a sudden-onset low abdominal pain. She had undergone uterine curettage 3 weeks before. Transvaginal sonogram of the cul-de-sac revealed complex fluid consistent with blood. On diagnostic laparoscopic operation, we found a ruptured cystic, conception-like structure near the right uterosacral ligament. Histology of the resected structure finally showed chorionic villi consistent with abdominal pregnancy. In this report, we present an unusual case of abdominal pregnancy. This case underscores the careful ultrasonic determination of gestational location at early pregnancy.

ression and quality of life of family caregivers of patients with Parkinson's disease(PD). METHODS: A cross-sectional descriptive study was conducted in one neurology outpatient clinic in Seoul, Korea from March to June, 2006. Sixty eight family caregivers of PD patients were participated to the study, using CES-D and SF-36. RESULTS: Mean scores of depression were 16.18+/-8.39 (range: 0-48) and it was a little lower than caregiver's who took care of Dementia patients and were higher than primary caregivers of the patients with Stroke. Time for caregiving, perceived severity, duration of PD were significantly related with depression respectively. Higher ADL scores which mean greater motor disabilities were related to higher caregiver depression. Lower income and greater medical expenditure were closely related with the depression of family caregivers respectively. The mean scores of total QOL were 435.5+/-96.5 and the mean scores of PF, SF, RE and MH were lower than general population. Time for caregiving, depression, patients' ADL scores were significantly associated with QOL respectively. People who were older and had lower educational background showed lower QOL scores respectively. CONCLUSION: Healthcare professionals should pay more attention to emotional aspects of caregivers who take care of PD patients, and develop comprehensive management strategies both for patients and their caregivers.

PURPOSE: Angiostatin, a 38 kDa internal fragment of plasminogen, is a potent inhibitor of angiogenesis. It blocks neovascularization and growth of primary and metastatic tumors in mice. To produce recombinant angiostatin protem comprising kringle 1-4 of plasminogen, we cloned the angiostatin cDNA from human liver tissue mRNA and expressed it in E. coli. MATERIALS AND METHODS: We cloned angiostatin cDNA from human liver tissue mRNA using reverse transcriptase polymerase chain reaction (RT-PCR) method. Cloned cDNA was ligated to pET22b (+) expression vector, transformed into E. coli stram BL21 (DE3) and expressed by IPTG induction. Recombinant human angiostatin protein was purified from the inclusion bodies of lysated bacterial pellet with 8 M urea solubilization, refolding, single step Lysine-Sepharose 4B affinity chromatography and 0.2 M E-aminocarproic acid elution. The anti-angiogenic activity of purified recombinant angiostatin was assayed with endothelial cell proliferation assay and chorioallantoic membrane assay (CAM). RESULTS: The identification of cloned angiostatin cDNA was confirmed by Southern hybridization and Pst I restriction enzyme digestion pattern. Angiostatin cDNA was expressed in E. coli, refolded in vitro and purified by Lysine Sepharose 4B affinity chromatography. The molecular weight of purified recombinant angiostatin was about 55 kDa on the SDS-PAGE. It inhibited the proliferation of bovine capillary endothelial (BCE) cells in vitro with a half-maximal inhibition concentration (ED50) of approximately 500 ng/mL. It also suppressed neovasculrization on the CAM assay. CONCLUSION: These results demonstrated that recombinant human angiostatin has similar function and biological activity compared with human angiostatin which is purified from porcine elastase digested human plasminogen fragment.

The author surveyed overall obesity indicies and factors concerned with obesity such as dietary intake, physical activity, stress and life style with the subject of doctors. The number of subjects was total 508 with 396 men and 112 women. They were subgrouped into surgical part, medical part and service and basic part by speciality. And also subgrouped into intern and resident, pay doctor, and practitioner by working type. The results were as follows. 1) Obesity indices: BMI of total doctor was 23.1+/-2.8, and WHR was 0.87+/-0.08 and overweight prevalence(BMI>25.0) was 23.6 %. It was within normal limit but slightly over the Korean standard. The degree of obesity indices of subgroups by speciality was "surgical part > medical part > service and basic part", and by working type was "practitioner > pay doctor > intern and resident". 2) Dietary intake and Physical activity: Average dietary intake was 2148+/-451 kcal/day. The degree of dietary intake by speciality was "surgical part > medical part > service and basic part". By working type it was "practitioner > pay doctor > intern and resident". Average physical activity was 29+/-5 METs/day. The degree of physical activity also showed similar pattern. But there was no significant difference among each groups. 3) Comparison between over-weight and non-over-weight group: The items that showed significant difference between two groups were dietary intake, skip breakfast, regular exercise, smoking, heavy drinking, chronic disease etc.
