1.Role Performance and Related Factors of the Clinical Research Coordinator.
Journal of Korean Academy of Nursing Administration 2011;17(4):524-537
PURPOSE: The purpose of this study was to analyze the role performance and related factors of the Clinical Research Coordinator (CRC). METHODS: A quantitative, cross-sectional design was used. Data were collected using a structured questionnaire from 134 Clinical Research Coordinators in 4 hospitals and analyzed using descriptive statistics, t-test, ANOVA, and Pearson correlation coefficient. RESULTS: The scores for role performance of CRC were high (average 336.51 points of a possible 420 points, mean average 5.74+/-0.67 of a possible 7) and the degree of role performance in the management task sub dimension (mean average 6.12+/-0.77 of a possible 7) was higher than any other sub dimension. Role performance of the CRC was also related to job satisfaction (r=.198, p=.023). CONCLUSION: The study results indicate that most CRC are nurses and perceive their role as very important. Further the CRC performance of activities of management task and the Coordination/Advocacy task sub dimension were high and higher levels of job satisfaction were related to higher levels of role performance of CRC was. Therefore, strategies related to improvement in the fringe benefit system and work environment should be developed to increase job satisfaction and thus increase job performance.

2.Factors Influencing Nurse Turnover Intention of Senior Convalescence Hospitals in the Metropolitan Area.
Korean Journal of Occupational Health Nursing 2016;25(3):156-167
PURPOSE: This study was a descriptive research to investigate the factors influencing nurses' turnover intention of Senior Convalescence hospitals in the metropolitan area. METHODS: A cross-sectional survey design was used. A questionnaire was distributed to the nurses in Senior Convalescence hospitals. The data of 210 nurses were analyzed using the descriptive statistics, t-test, ANOVA, Pearson correlation coefficient and multiple regression. RESULTS: Turnover intention was significantly correlated with professionalism, job involvement, organizational commitment, job stress, practice environment. Organizational commitment, job stress, age, and practice environment were identified as factors influencing turnover intention. These factors explained 53.3% of variance of turnover intention. CONCLUSION: The results suggest that strategies to decrease turnover intention should be discussed and continued to develop ways to establish organizational commitment, to lower job stress levels and to improve practice environment of nursing work. And further study is needed to identify the key mechanism in nurses' turnover intention of Senior Convalescence hospitals.

The Lambert-Eaton myasthenic syndrome (LEMS) is a rare disorder of neuromuscular transmission that is frequently associated with malignancy, particulary small cell carcinoma of the lung. To our knowledge, there was no report of LEMS in Korean listeratures and this might be the first case in this country. The patient is a 55 year old man with muscle weakness and fatigability of proximal lower limbs for 2 months. Bronchogenic carcinoma is confirmed radiologically and pathologically. The electrophysiological studies suppert the clinical diagnosis of LEMS with (1) low amplitude of evoked compound muscle potential to a single supramaximal stimulus on nerve, (2) significant decremental response at low rates of stimulation and (3) marked incremental response at high rates of stimulation.

5.The Current State and Quality Assessment of Nursing Intervention Study in Occupational Health Nursing of Korea
Korean Journal of Occupational Health Nursing 2019;28(1):21-35
PURPOSE: The purpose of this study is to propose directions for the development of Occupational Health Nursing Intervention by identifying the current status and quality of Occupational Health Nursing Intervention Research in domestic industries. METHODS: Between 2000 and August of 2018, total of 1,181 Occupational Health Nursing related published references were searched using 4 domestic databases, and of the total, 29 final theses that suited the requirements were analysed In this research, the quality assessment of literature that were selected as suitable was conducted using a tool for assessing the biasing risk of non-randomized studies, RoBANS(Risk of Biasing Assessment Tool for Non-randomized Study). RESULTS: For all research, nonequivalent control group pre-posttest design was the most used as quasi-experimental designs. The effectiveness of intervention was found both in terms of physical and psychological aspects, and the result of the risk of biasing assessment showed a high risk levels in both “confounding variables” and “detection bias”. CONCLUSION: Occupational Health Nursing Intervention have been steadily making improvements in terms of both quality and quantity, and as for more effective intervention developments that improves the physical and mental health of the workers, supplementation in strict research design and in ethical aspects deems necessary.

Journal of Korean Academy of Nursing 2022;52(2):214-227
Purpose:
This study was aimed at investigating the incidence and risk factors of dyslipidemia in menopausal women using a Korean community-based longitudinal study.
Methods:
The subjects were 245 postmenopausal women without dyslipidemia who had participated in the Ansan-Ansung cohort study from 2001~2002 (baseline) to 2015~2016 (seventh follow-up visit). The dyslipidemia incidence was measured as incidence proportion (%) and incidence rate per 100 person-years. The predictors of developing dyslipidemia were analyzed with Cox’s proportional hazard model.
Results:
The incidence of new dyslipidemia during the follow-up period was 78.4% (192 patients), and 11.9 per 100 person-years. Mean duration from menopause to developing dyslipidemia was 5.3 years in new dyslipidemia cases. The triglyceride/high density lipoprotein (TG/HDL-C) ratio at baseline (hazard ratio = 2.20; 95% confidence interval = 1.39~3.48) was independently associated with developing dyslipidemia.
Conclusion
Dyslipidemia occurs frequently in postmenopausal women, principally within five years after menopause. Therefore, steps must be taken to prevent dyslipidemia immediately after menopause, particularly in women with a high TG/HDL-C ratio at the start of menopause.

PURPOSE: To evaluate the ultrasonographic findings of BCG lymphadenitis complicated by BCG vaccination in children MATERIALS AND METHODS: Ultrasonography was performed for 22 cases of BCG lymphadenitis in 21 patients who were diagnosed by clinical (n=10) or pathological (n=11) examinations. Their age ranged from 4 months to 3 years (mean age; 14 months). We retrospectively analyzed the ultrasonographic findings for location, multiplicity, size, shape, margin, echogenecity, posterior enhancement, calcifications, inner anechoic portion and Doppler pattern of the BCG lymphadenitis. RESULTS: The BCG lymphadenitis was found at the axillary area in 15 cases (68%) and at the supraclavicular area in 7 cases (32%). There were ten cases (45%) of solitary lesion and 12 cases (55%) of multiple conglomerated lesions. The maximum diameter ranged from about 0.9 cm to 3.2 cm. The BCG lymphadenitis showed as round (82%), well defined (86%), or heterogeneous hypoechoic (68%) lesions with posterior enhancement (78%). Calcifications were found in 6 cases (27%) and 5 cases (83%) had been vaccinated more than 5 months ago. There were eccentric inner anechoic portions in 16 cases (73%), which were pathologically confirmed as having caseating necrosis. There were increased Doppler flow patterns in 15 cases (68%); 4 cases (18%) were of the central type, 6 cases (27%) were of the peripheral type and 5 cases (23%) were of mixed type. CONCLUSION: BCG lymphadenitis is frequently located at the axillary area adjacent to a vaccination site. The ultrasonographic findings of BCG lymphadenitis are well-defined, round, heterogeneously hypoechoic lesions with posterior enhancement, calcifications and inner eccentric anechoic portion.

Journal of the Korean Neurological Association 2015;33(4):306-309
Tumarkin's otolithic crisis refers to drop attacks that are an unusual manifestation of Meniere's disease. It has been proposed that these drop attacks result from mechanical deformation of the otolithic organs related to the endolymphatic hydrops that occurs in Meniere's disease, as revealed by MRI with intratympanic gadolinium enhancement. Here we report a patient with Tumarkin's otolithic crisis in whom inner-ear MRI with intratympanic gadolinium administration during the acute attack did not reveal the presence of endolymphatic hydrops.

The Mainz classification for renal cell tumors was introduced in 1986 and it's utility has been reported in several histogenetic and genetic studies of renal cell tumors. We present a study of 127 cases of renal cell tumors with clinicopathologic correlation, DNA content analysis, and histogenesis studied by histochemical and immunohistochemical staining. The 127 renal cell tumors classified by the Mainz classification were 87 clear cell, 17 chromophilic, 13 chromophobe and 3 sarcomatoid renal cell carcinomas, 5 oncocytomas and 2 adenomas. These subtypes showed significant correlation not with age, sex, Robson's stage, DNA ploidy or tumor recurrence but with nuclear grade (p=0.001) and tumor size (p=0.001). Hall's colloidal iron (p=0.002) and carbonic anhydrase II (p=0.013) stains, representing the origin of distal nephron especially of collecting duct, were significantly correlated with specific subtypes of renal cell tumors, especially chromophobe cell renal carcinoma. This study demonstrates that the Mainz classification suggests several morphologically different subtypes and variants of renal cell tumors and that some of them may have originated from the distal nephron, particularly from the collecting duct.
