PURPOSE: The purpose of this study was to explore the clear concept of organizational commitment for effective nursing personnel management. METHOD: This study was conducted using Walker & Avant's conceptual analysis framework(2005). RESULTS: Organizational commitment was identified with six attributes: acknowledgment, acceptance, trust, sacrifice, attachment, regulation. Antecedents of organizational commitment were personal characteristics, perceived organizational support, empowerment, fair compensation, job satisfaction, job autonomy, organizational culture, and leadership. Consequences of organizational commitment were turnover intention, job performance and organizational citizenship behavior. CONCLUSION: Organization commitment is a core concept for understanding the management of nursing personnel. Appropriate instruments to operationalize the concept of organizational commitment including six attributes need to be developed.

PURPOSE: The purpose of this study was to identify the moderating effect of interpersonal skills on the relationship between childhood emotional trauma and depression. METHODS: From June to July, 2017, a convenience sample of 226 nursing students was recruited. Research data were collected through self-report questionnaires and analyzed using SPSS version 22.0. RESULTS: 68.1% (154) respondents experienced emotional abuse, and 48.1% (110) emotional neglect in childhood emotional trauma. The average depression score was 10.76. There were 54.4% (123), 34.5% (78), 12.8% (29), and 7.1% (16) of respondents with mild, moderate, and severe depression, respectively. The average interpersonal skills score was 3.59. There was a significant correlation between childhood emotional trauma (emotional abuse, emotional neglect), interpersonal skills and depression. And the moderating effect of interpersonal skills on the relationship between childhood emotional neglect and depression was significant. CONCLUSION: Interpersonal skills play a role as a moderating variable influencing the relationship between emotional neglect of childhood emotional trauma and depression, and also reduce the effects of childhood emotional trauma on depression. When developing a depression prevention program for nursing college students, such programs should consider strategies to reduce the negative effects of childhood emotional trauma and to improve interpersonal skills.

PURPOSE: The purpose of this study is to analyze the intervention studies for married immigrant women. METHODS: Based on inclusion criteria, 45 articles published from 2006 to 2011 were reviewed and analyzed. RESULTS: Among the total amount of studies, 77.8% have been conducted since 2009; and 46.7% of them were for a master's thesis, 11.1% were for a doctoral thesis, and 42.2% were journal articles. Most of them were quantitative research (77.8%) and 71.1% were conducted in urban areas. The most frequently conducted intervention was art therapy (35.6%), whereas 6.7% was health education. In total, 104 outcome indicators were used with 57 (54.8%) in the mental health domain, 29 (27.9%) in the social health domain, and 18 (17.3%) in the physical health domain. The most commonly used outcome indicator was self-esteem (23.2%), and the next, in the order of frequency, included self-efficacy (23.2%), acculturative stress (21.4%), and depression (10.7%). CONCLUSION: Most intervention studies were conducted to support the sociocultural adaptation of married immigrant women, while few intervention studies were conducted to support the health of married immigrant women. To promote the health and quality of life of married immigrant women, many health related intervention programs should be undertaken.

PURPOSE: The purpose of this study was to investigate the contraceptive knowledge and practice among married immigrant women. METHODS: A cross-sectional survey design with a convenient sampling was used. 170 married immigrant women were recruited in Daejeon city and Chungcheong area. A structured questionnaire was self-administered from November 1, 2011 to January 13, 2012. RESULTS: 48.2% of subjects have used contraceptive practice. The widely used contraception methods were IUD, condom, oral pill and withdrawal. 73.2% of subjects got information about contraception from family and friends, and 18.3% of subjects had no source of information. The subjects' employment state (p = .006), duration of marriage (p = .019), number of baby (p = .021), family type (p = .046) have a significant influence on their contraceptive practice. The subjects' mean score of contraceptive knowledge was very low (5.72 points out of 15 points). There were significant differences in subjects' contraceptive knowledge depending on their education level (p = .002), employment state (p < .001), country of origin (p = .010), and family type (p = .003). CONCLUSION: To improve contraceptive knowledge and practice for married immigrant women, it is necessary to develop a proper contraceptive education program to enhance contraceptive knowledge and practice. Adjusted education program by this results will contribute to increase sexual health for married immigrant women.

The natural killer(NK) cell activity of mononuclear cells (MNC) from peripheral blood (PB) and synovial fluid (SF) of 40 rheumatoid arthritis(RA) patients was investigated by employing 51-chromium-(51Cr) release microcytotoxicity and single cell cytotoxicity assays against K562 target cells. It has been revealed that SF-MNC from RA patients showed a significantly lower NK activity than PB-MNC from the same patients and this might be due to an impaired target binding capacity of the effector cells and not due to a deficiency of active NK cells.

PURPOSE: This study aimed to identify the early predictors of neurodevelopmental outcomes in infants undergoing therapeutic hypothermia for neonatal hypoxic ischemic encephalopathy. METHODS: The medical records of 24 neonates who underwent hypothermia therapy for hypoxic ischemic encephalopathy at the neonatal intensive care unit of Yeouido St. Mary's Hospital of the Catholic University of Korea between August 2013 and May 2016 were reviewed. Patients were divided into two groups according to their neurological outcome at the age of 18 to 24 months: a normal group (n=14), which included patients with normal neurological function, and an abnormal group (n=10), which included patients with neurological deficits. The clinical characteristics, clinical outcomes, and laboratory findings before and after hypothermia treatment were compared between the groups. RESULTS: There were no significant differences in the demographic characteristics between the two groups. With regard to clinical outcomes, only brain magnetic resonance imaging (MRI) findings showed significant differences between the normal and abnormal groups (21.4% vs. 100.0%, P < 0.001). With regard to laboratory findings, there were significant differences in the white blood cell (WBC) count after hypothermia treatment between the normal and abnormal groups (9.78±3.52 vs. 14.90±3.48, P=0.003). However, logistic regression analysis showed that the WBC count was not an independent risk factor for abnormal neurodevelopment (P>0.05). CONCLUSION: The presence of abnormal lesions on MRI was the most useful predictor of poor neurodevelopmental outcome in infants treated with therapeutic hypothermia after perinatal asphyxia.

The Ael subgroup expresses the least amount of A antigens and could only be detected by performing the adsorption-elution test. The frequency of the Ael subgroup is about 0.001% in Koreans, and the Ael02 allele, which originates from A102, is the most frequently identified allele in the Korean population. We report a Korean family with the Ael03 allele identified by molecular genetic analysis. To the best of our knowledge, this is the first such report in Korea to date.

STATEMENT OF PROBLEM: The adhesion between titanium and ceramic is less optimal than conventional metal-ceramic bonding, due to reaction layer form on cast titanium surface during porcelain firing. PURPOSE: This study characterized the effect of titanium-ceramic adhesion after gold and TiN coating on cast and wrought titanium substrates. MATERIAL AND METHOD: Six groups of ASTM grade II commercially pure titanium and cast titanium specimens(13mm x 13mm x 1mm) were prepared(n=8). The conventional Au-Pd-In alloy served as the control. All specimens were sandblasted with 110micrometer Al2O3 particles and ultrasonically cleaned for 5min in deionized water, and dried in air before porcelain firing. An ultra-low-fusing dental porcelain(Vita Titankeramik) was fused on titanium surfaces. Porcelain was debonded by a biaxial flexure test at a cross head speed of 0.25mm/min. The excellent titanium-ceramic adherence was exhibited by the presence of a dentin porcelain layer on the specimen surface after the biaxial flexure test. Area fraction of adherent porcelain(AFAP) was determined by SEM/EDS. Numerical results were statistically analyzed by one-way ANOVA and Student- Newman-Keuls test at alpha=0.05. RESULTS: The AFAP value of cast titanium was greatest in the group 2 with TiN coating, followed by group 1 with Au coating and the group 3 with Al2O3 sandblasting. Significant statistical difference was found between the group 1, 2 and the group 3 (p<.05). The AFAP value of wrought titanium was greatest in the group 5 with TiN coating, followed by the group 4 with Au coating and the group 6 with Al2O3 sandblasting. CONCLUSION: No significant difference was observed among the three groups (p>.05). The AFAP values of the cast titanium and the wrought titanium were similar. However the group treated with Al2O3 sandblasting showed significantly lower value (p<.05).

BACKGROUND: Staphylococcus aureus (S. aureus) and Escherichia coli (E. coli) are major pathogens in community and hospital. And they sometimes cause the outbreak in hospital in the immunocompromised patients. Pulsed-field gel electrophoresis (PFGE) has been regarded as a standard method for genotyping in epidemiologic studies, but it is laborious and time-consuming. Infrequent restriction site-polymerase chain reaction (IRS-PCR), a new genotyping methods, was performed to compare the applicability with PFGE. METHODS: We performed PFGE and IRS-PCR on S. aurues (n=120) and E. coli (n=117) which were collected clinically in 4 different hospitals. We assessed each method in terms of discriminatory power, quality, and efficiency. RESULTS: In E. coli, the discriminatory power of IRS-PCR was 46.7apprx86.7%, and that of PFGE was 88.9apprx96.7% according to hospital. But in S. aurues, the discriminatory power of IRS-PCR was 20apprx56.7%, and that of PFGE was 40apprx90% according to hospital. The typicality and reproducibility of IRS-PCR were 100% of each. PFGE needed four days to complete the procedure, but IRS-PCR could be performed within one day, IRS-PCR showed better resolution than PFGE. CONCLUSION: In case of gram negative bacteria (like E. coli), IRS-PCR could be a reliable alternative for epidemiologic typing due to better efficiency and comparable discriminatory power. But in the case of gram positive bacteria (like S. aureus), IRS-PCR does not seem to be suitable for the strain-to-strain differentiation. More trials and changes of restriction enzymes or primers could reveal the efficacy of IRS-PCR in the field of molecular typing.

PURPOSE: We analyzed pelvic ultrasonography (USG) findings in girls with central precocious puberty (CPP) and assessed the role of uterine and ovarian measurements in discriminating between CPP and other pubertal conditions. METHODS: Seventy-four girls (chronological age 7.8 +/- 0.5 years, bone age 9.9 +/- 0.8 years) with precocious pubertal signs were enrolled. Measurements of uterine and ovarian parameters by pelvic USG included antero-posterior diameters of the uterine fundus and cervix, diameter of each ovary, number of follicles, and maximal diameter of the largest follicle. The pelvic USG parameters were compared between girls with CPP (n = 49) and girls with atypical premature thelarche (PT) (n = 25). RESULTS: Antero-posterior diameter of uterine fundus (1.05 +/- 0.34 vs. 0.74 +/- 0.78 cm, P = 0.001), maximal ovarian diameter (2.13 +/- 0.48 vs. 1.84 +/- 0.74 cm, P = 0.048) and mean ovarian area (2.31 +/- 0.79 vs. 1.69 +/- 0.71 cm, P = 0.002) were significantly greater in girls with CPP than in girls with atypical PT. For the diagnosis of CPP, the sensitivity and specificity of A-P diameter of uterine fundus (> 0.9 cm) was 65.3% and 84.0%, the sensitivity and specificity of maximal ovarian diameter (> 2.0 cm) was 55.1% and 76%, and the sensitivity and specificity of mean ovarian area (> 2.0 cm2) was 62.9% and 80.0%. CONCLUSION: Girls with CPP had significantly higher dimensions of the uterus and ovary measurements compared to girls with atypical PT, but sensitivity and specificity were not high enough to differentiate CPP from atypical PT. Pelvic USG may help the diagnosis of CPP in girls.
