PURPOSE: This study was done to clarify nurses' duties, tasks and task elements and to develop a job description for clinical nurses on general and intensive care units in tertiary-level hospitals, and dramatically reflect changing medical trends in Korea. METHODS: The job description was developed based on the Developing a Curriculum Method (DACUM). The questionnaire included frequency, importance, and difficulty of duties, tasks and task elements, measured on a 4-point scale. Results were analyzed using SPSS version 21.0. Data were collected from September 4 to 7, 2017, and analyzed using descriptive statistics and a scattered graph. RESULTS: The job description consisted of 10 duties, 38 tasks, and 51 elements. Of the 10 duties, the highest duty in order of importance was ‘Direct nursing care’ followed by ‘Infection control’. The highest duties according to frequency and difficulty were ‘Document and notify’ and ‘Research and quality improvement’. ‘Safety management’ and ‘Infection control’ were considered as relatively simple duties, however, these two duties were still included as important jobs for clinical nurses. CONCLUSION: The job descriptions for clinical nurses developed from this study contain nursing ethics and safety as well as infection control, to faithfully reflect clinical nurses' jobs.

We report a case of a large asymptomatic Rathke cleft cyst in a 14-year-old boy. This cyst was of considerable size, measuring 2x1.8x1.8 cm, but did not produce any symptoms and was confined to the suprasellar area. The cyst wall was lined by pseudostratified ciliated columnar epithelium with goblet cells. The lining epithelium of the Rathke cleft cyst was immnoreactive for cytokeratin, EMA and CEA.

Reactive human mesothelial cells were examined by immunocytochemical stain with intermediate filaments(cytokeratin [CK1, CK7, CK8, CK18, CD19/, vimentin, desmin, actin), epithelial membrane antigen, carcinoembryonic antigen(CEA), MHC class II antigen(HLA-DR), LeuM-1(CD15), alpha1-antitrypsin(ACT), alpha1-antichymotrypsin (ACHT), CD68(KP-1) and FcgammaRIII(CD16). The mesothelial cells were isolated from patients with liver cirrhosis and pleural effusion, and short-term cultured in RPMI 1640 media containing 10% heat inactivated fetal calf serum and 1% identical supernatant fluid of the patients' transudates. The results obtained are as follows. 1. The cultured-reactive mesothelial cells were positive for the protein of cytoskeleton such as cytokeratin and vimentin, but negative for desmin and actin. The resting mesothelial cells showed positive reactions for cytokeratin, but negative for vimentin, desmin and actin. 2. The primary antibodies to the cytokeratin were strongly reactive for CK1, CK8 and CK18 but negative for CK7 and CK19 in both reactive and resting mesothelial cells. 3. Resting mesothelial cells showed negative reactions for CEA, but strong positive reactions in cultured-reactive mesothelial cells. 4. The markers for the monocytes\histiocytes (CD11b, CD14, CD16, CD68, lysozyme and alpha1-antitrypsin and alpha1-antichymotrypsin) were nonreactive in resting mesothelial cells, but lysozyme and alpha1-antitrypsin were weakly reactive in reactive and proliferative mesothelial cells. 5. MHC Class II molecule(HLA-DR antigen) was negative in both resting and reactive mesothelial cells. These results suggest that the short-term cultured, reactive mesothelial cells show a newly aberrant expression of the vimentin and carcino-embryonic antigen. The reason of the aberrant expression of the intermediate filament and oncofetal antigen in reactive and proliferative mesothelial cells should be further evaluated.

Sixty-three patients with permanent sigmoid colostomy were surveyed to evaluate their satisfaction and complications with the "irrigation technique" and the "atural evacuation" of the colostomy management (irrigation technique; 32 patients, natural evacuation; 31 patients). All patients had colostomy for at least 12 months without disease recurrence. Each patient was interviewed in addition to standard questionnaire. The irrigation was not associated with any major complication including colonic perforation. The irrigation was used younger age group than the natural evacuation (53+/-10 vs. 62+/-12, P=0.01). The frequency of bowel movement was lower in the irrigation than in the natural evacuation (5.1+/-2.5/wk vs. 10.8+/-9.0/wk, P=0.04). Five patients (16%) of the irrigation experienced spontaneous bowel action but only one patient suffered from it. The time spent for managing irrigation was 59+/-13 minutes. Twenty-three patients (74%) of the natural evacuation suffered from one or moreproblems such as expensive apparatus, leakage, skin irritation or odor. Sixteen patients (52%) of the natural evacuation and 2 patients (6%) of the irrigation were restricted in social activity (P=0.0001). Thirteen patients (42%) of the natural evacuation and 1 patient (3%) of the irrigation were dissatisfied with colostomy management (P=0.002). Thus, the irrigation technique seems to be more effective and satisfactory method for managing colostomy without compromising patient's social activity when it is performed in appropriately selected patients.

Genes of cancer-associated testis antigens (CTAs) are expressed in various cancer tissues. In order to use CTAs as cancer diagnosis marker, we developed molecular method for detection of CTAs transcripts in tissue. In order to know the applicability of DNA of cancer-associated testis antigens (CTAs) on cancer diagnosis, molecular diagnostic methods for detection of gene expression of melanoma antigen gene (MAGE), GAGE, and B melanoma antigen (BAGE) was studied. After comparing DNA sequences of CTAs, S1/AS1 and S2/AS2, GAGE-S/ GAGE-AS, and BAGE-S/BAGE-AS primers were designed for the detection of MAGEs, GAGEs and BAGEs, respectively. The gene expression of CTAs in cancer cell lines, head and neck cancer tissues, ovary cancer tissue, and peritoneal cells of gastric cancer patients were investigated by reverse transcription-polymerase chain reaction (RT-PCR) using these primers. The MAGEs, GAGEs and BAGE genes were expressed in 8/8 (100%), 5/8 (62.5%) and 1/8 (12.5%) of head and neck cancer tissues, respectively. The gene expression of MAGEs were also detected in 8/10 (80%) of ovary cancer tissues and in 9/10 (90%) of peritoneal cells of gastric cancer patients in RT-PCR test using S1/AS1 primers. The results of this study suggest that molecular diagnosis method using CTAs genes, especially RT-PCR using S1/AS1 primer combination, is useful for diagnosis of cancer and it will be used for the prediction of cancer progression or regression and metastasis in future.

Purpose: : This study aims to identify job stress, emotional intelligence, and exhaustion of the nurses in comprehensive nursing service units and then verify the moderating and mediating effects of emotional intelligence on the relationship between job stress and exhaustion. Methods: : Participants are 118 nurses working in two general hospitals. The collected data are analyzed using the SPSS WIN 27.0 and AMOS 18.0 programs by assessing frequency and percentage, mean and standard deviation, independent t-test and one-way ANOVA, Scheffé test, Pearson correlation coefficient, and hierarchical multiple regression analysis and bootstrapping. Results: : Exhaustion has a statistically significant positive correlation with job stress (r=.40, p ＜.001) and a statistically significant negative correlation with emotional intelligence (r=-.26, p =.004). A partial mediating effect of emotional intelligence is found between job stress and exhaustion, however, there is no moderating effect. Conclusion : It is expected that to reduce the exhaustion of nurses in comprehensive nursing service units, it is necessary to assess job stress and emotional intelligence, and strengthen emotional intelligence along with job stress intervention.

PURPOSE: This study aimed to synthesize the caring experiences of Korean family members of patients with dementia through a qualitative meta-synthesis method. METHODS: By searching through nine Korean and English databases, we compared 37 qualitative studies on caring experiences of family members of patients with dementia. The selected studies were synthesized through meta-synthesis, proposed by Sandelowski and Barroso (2007). RESULTS: The meta-synthesis elicited four themes: tough life due to care for patients, changes in relationships, adaptation to caregiver's roles, and new perspectives of life through personal growth. Caregivers were shocked when a sudden diagnosis of dementia was made prior to any preparation on their part. They were tied to their patients all the time and their mind and body got exhausted. Their relationship with patients began to change and they looked at them differently. They experienced conflicts with the other non-caring family members and were alienated from them. They were also socially isolated. However, by building their own care strategies and utilizing social resources, they gradually adapted to their caregiver roles. Finally, they experienced personal growth and acquired a new perspective toward life by accepting their roles and finding meaning in their lives. Shifting the caregiver's centricity from themselves to the patient was the process of becoming human beings who actively constructed their realities while giving meaning to their painful lives and interacting with the environment. CONCLUSION: The results of the study can be useful for nurses in understanding the experiences of caregivers of the patients with dementia and in providing them with practical interventions.

The purpose of this study was to compare the shaping time of two shaping methods and the leakage of three different obturation techniques. Ninty three canaled human molar teeth were used, which were randomly divided into two groups of forty teeth each and ten control teeth. After working length determination, the one group was prepared crown-down technique using rotary root canal instruments of GT rotary files .12/20, .10/20, .08/20 and .06/20 taper(Maillefer Instrument SA. Switzerland). The other group was instrumented with Gates Glidden burs(#1, #2, and #3) to coronal preparation and GT rotary files .08/20 and .06/20 taper to apical preparation. Shaping time was measured. After root canals were instrumented, they were divided to three subgroups and obturated as follows: Subgroup 1, obturated with single cone method : Subgroup 2, obturated with lateral condensation : Subgroup 3, obturated with continuous wave technique. Three subgroups were obturated using non-standardized gutta-percha cone(Diadent, Korea, .06 or .08 taper) and AH-26(Dentsply DeTrey, Germany) as a root canal cement. Ten unobturated teeth served as positive and negative controls. After immersion in 2% methylene blue solution for 1 month, the teeth were washed during 24h. The teeth were demineralized in 10% nitric acid and dehydrated by immersion in 80, 90 and 100% ethyl alcohol. The teeth were finally cleared and stored in 100% methylsalicylate, and apical dye penetration was evaluated under stereomicroscope (Leica M420, LC, U.S.A) at x8.75 magnification. Liner measurement of dye penetration was assessed with the use of digitalized image analysing system (analySIS, GmbH, Germany). The data were analysed statistically using independent T-test and Two-way ANOVA and Tukey test. The result were as follows: 1. In canal prepared with GT(TM)rotary file, shaphing time taked more than the group of using Gates Glidden drill to coronal preparation without statistical significance (p>0.05). 2. The group of single cone obturation using canal preparation of GT(TM) rotary files showed significantly more apical leakage than those of lateral condensation and continuous wave technique regardless of shaping method (p<0.05). 3. The group of single cone obturation using canal preparation of GT(TM) rotary files and Gates Glidden drill showed significantly more apical leakage than those of continuous wave technique regardless of shaping method (p<0.05). 4. Regardless of shaping method, The group of continuous wave obturation showed less apical leakage than those of lateral condensation without statistical significance (p>0.05). 5. The group of single cone obturation using canal preparation of GT(TM) rotary files and Gates Glidden drill showed more apical leakage than the group of lateral condensation using same shaping method without statistical significance (p>0.05).
