Purpose: Carbapenemase-producing Enterobacteriaceae (CPE) are associated with considerable mortality. This study was aimed to identify survival factors among medical care unit patients with CPE. Methods: We conducted a retrospective cohort; data were collected from September 2017 to June 2019 through electronic medical records. The data collected were general characteristics, disease-related characteristics, severity-related characteristics, and treatment-related characteristics. Data were analyzed based on frequency, mean, standard deviation, Chi-square test, Fisher's exact test, t-test, Pearson's correlation coefficient, and Cox proportional hazard model using SPSS/WIN 21.0 program. Results: Seventy-seven patients were included (59 survivors and 18 deceased) in the study. Univariate analysis identified factors for survival associated with acquired CPE as age (t= -1.56, p= .037), simplified acute physiology 3 (SAPS3) score of admission date (t= -2.85, p= .006), Glasgow coma scale (GCS) of CPE acquisition date (t= 2.38, p= .020), artery catheter at CPE acquisition date (χ²= 4.58, p= .032), vasoconstrictor agents use at CPE acquisition date (χ²= 6.81, p= .009), platelet at CPE acquisition date (t= 2.27, p= .025), lymphocyte at CPE acquisition date (t= 2.01, p= .048), calcium at CPE acquisition date (t= 2.68, p= .009), albumin at CPE acquisition date (t= 2.29, p= .025), and creatinine at CPE acquisition date (t= 2.24, p= .028). Multivariate Cox proportional hazard model showed that GCS at CPE acquisition date (HR= 1.14, 95% CI= 1.05-1.22), lymphocyte at CPE acquisition date (HR= 1.05, 95% CI= 1.00-1.10), and creatinine at CPE acquisition date (HR= 1.25, 95% CI= 1.04-1.49) were independent survival factors among medical intensive care unit patients with CPE. Conclusion: Based on the study results, it is necessary to develop nursing interventions that can aid in the management of patients with CPE and identify their effects.

The purpose of this study is to examine the relationships of transformational leadership, job satisfaction, and organizational commitment on the training persons in a certain vocational training center. The major research findings as follows. First, Statistically significant positive relations were found between the transformational leadership and job satisfaction. Especially, Sub-construct for transformational leadership e.g., charisma(${\beta}=.24$, P<.05) and intellectual stimulation(${\beta}=.36$, p<.001) showed statistically significant positive(+) relationship with construct in job satisfaction. Second, Statistically significant positive relations were found between the transformational leadership and organizational commitment. Especially, Sub-construct for transformational leadership e.g., intellectual stimulation(${\beta}=.29$, p<.01) and inspirational motivation(${\beta}=.24$, p<.05) showed statistically significant positive(+) relationship with construct in organizational commitment. These consequences suggest that transformational leadership affect the job satisfaction and organizational commitment.

The seven selected primers BION-13, BION-29, BION-61, BION-64, BION-68, BION-72 and BION-80 generated the total number of loci, average number of loci per lane and specific loci in Meretrix lusoria (ML), Saxidomus purpuratus (SP) and Cyclina sinensis (CS) species. Here, the complexity of the banding patterns varied dramatically between the primers from the three venerid clam species. The higher fragment sizes (> 1,000 bp) are much more observed in the SP species. The primer BION-68 generated 21 unique loci to each species, which were ascertaining each species, approximately 150 bp, 300 bp and 450 bp, in the ML species. Remarkably, the primer BION-80 detected 7 shared loci by the three clam species, major and/or minor fragments of sizes 500 bp, which were matching in all samples. As regards average bandsharing value (BS) results, individuals from CS clam species (0.754) exhibited higher bandsharing values than did individuals from SP clam species (0.607) (P < 0.05). In this study, the dendrogram obtained by the seven oligonucleotides primers indicates three genetic clusters: cluster 1 (LUSORIA01-LUSORIA07), cluster 2 (PURPURATUS08-PURPURATUS14), cluster 3 (SINENSIS15-SINENSIS21). Among the twenty one venerid clams, the shortest genetic distance that displayed significant molecular differences was between individuals 18 and 20 from the CS species (genetic distance = 0.071), while the longest genetic distance among the twenty-one individuals that displayed significant molecular differences was between individuals LUSORIA no. 02 and PURPURATUS no. 09 (genetic distance = 0.778). Relatively, individuals of SP venerid species were appropriately closely related to that of CS species, as shown in the hierarchical dendrogram of genetic distances. Eventually, PCR fragments exposed in the present study may be worthwhile as a DNA marker the three venerid clam species to discriminate.

It has been established that hypercholesterolemia is a major risk factor for atherosclerosis. Recent data showed that the incidence of hypercholesterolemia increase in Korea. n-3 Fatty acids lower serum triglyceride profoundly but the effect on serum cholesterol is not clear. This study was performed to assess the effects of low and moderate supplementation of marine n-3 fatty fish on serum cholesterol in young healthy korean woman. Nineteen subjects were divided into two groups. Each group receive an experimental diet supplemented with either 100g (group I) or 200g mackeral(Scomber japonicus) fish(group II) for 1-week. The diet was designed to avoid in which the amount of n-6 fatty acids would be much greater than that of n-3 fatty acids. MUFA, SFA intakes were similar in the two diets. The ratio of n-6/n-3 fatty acids was 1 : 1.l for group I, 1 : 2.51 for group II. The average daily n-3 fatty acids consumption from fish was 3.87g/day (1.03g EPA, 2.84g DHA)for group I, 7.74g/day (2.06g EPA, 5.68g DHA) for group II. Blood samples were obtained 2 times before experimental diet, immediately after experimental diet for 1-week. After experimental diet for 1-week, the serum total-cholesterol levels decreased significantly (16.4$\pm$15.1mg/dl, p<0.01) in group II and lowered slightly (13.7$\pm$25.8mg/dl)in group I. There were no significant changes from baseline to the end of the study in serum HDL-cholesteol, LDL-cholesterol, HDL-C/T-C ratio, and LDC-C/HDL-C ratio. The results suggest that the moderate levels of marine n-3 fatty fish consumption could improve serum cholesterol in normal subjects, therefore in might be of value in the prevention of atherosclerosis. However the clinical usefulness of moderate n-3 fatty fish consumption of hypercholesterolemic subjects will require further study. Also further studies are required to elucidate the long-term effects of low n-3 fatty fish consumtion.

The recently introduced castable glass ceramics incorporate properties characteristic of natural teeth and they are regarded as an ideal material to restore lost tooth structure. The purpose of this study was to compare the marginal fit of castable ceramic crown with that of the metal-ceramic crown in the process of heat treatment. Two master dies for castable ceramic crowns and metal-ceramic crowns were fabricated from being cast with the base metal. Each master die was duplicated with addition silicone and hard stone. Ten castable ceramic crowns were made on each hard stone die and their marginal openings were measured three times first, after casting; second, after ceramming; third, after shading. The other ten metal-ceramic crowns were made on each hard stone die and their marginal openings were measured three times : first, after casting; second, after degassing; third, after porcelain veneering. Each crown was seated on its master die with the constant force delivered by loading jig. And then, marginal openings were measured on four locations by optical projector at X50 magnification. The results were as follows: 1. The mean marginal openings of castable ceramic crowns were $31.1{\pm}12.7{\mu}m$ after casting; $44.6{\pm}12.8{\mu}m$ after ceramming; $51.2{\pm}16.8{\mu}m$ after shading. 2. The mean marginal openings of the metal-ceramic crowns were $26.2{\pm}13.8{\mu}m$ after casting; $29.8{\pm}10.3{\mu}m$ after degassing; $38.0{\pm}14.5{\mu}m$ after porcelain veneering. 3. There was significant increase in the marginal opening of castable ceramic crowns after ceramming, while metal-ceramic crowns sho(wed significant increase after porcelain veneering (p<0.05). 4. Marginal fit of metal-ceramic crown was better than that of castable ceramic crown (p<0.01).

This study investigated the relationships between Work-related musculoskeletal disorders (WMSDs), contributing factors, and the occupational stress of physical therapists. Self-reported questionnaires were given to 180 physical therapists in Gangwon Province. Variables examined included the prevalence of pain sites related to WMSDs; pain intensity; pain pattern; and job stress, which is thought to involve the physical environment; job demand; insufficient job control; interpersonal conflict; job insecurity; organizational system; reward system; and occupational culture. Among physical therapists, work-related musculoskeletal pain commonly affected the low back (30.1%), shoulder (29.3%), and wrist (12.2%). The sites of work-related musculoskeletal pain treated medically were the low back (22.8%), shoulder (19.8%), neck (12.7%), and wrist (12.1%). "Repeating the same work constantly" was suggested to be the major cause of the pain. The younger therapists were significantly more likely to feel high job stress due to the physical environment (p<.05), job demand (p<.05), and organizational system (p<.01). Women were more likely to feel greater job stress related to job demand, insufficient job control, the organization system, and job rewards. Men were more likely to feel greater job stress related to job insecurity. Weak positive relationships were observed between work-related musculoskeletal pain and job stress, which is thought to involve the physical environment; job demand; insufficient job control; interpersonal conflict; job insecurity; organizational system; reward system; and occupational culture. Physical therapists appear to be at higher risk of WMSDs because 80.1% of the physical therapists studied experienced work-related musculoskeletal pain. To reduce the risk, we need intervention strategies such as preventive education, ergonomically designed medical equipment, a psychosocial approach to work conditions, improved mechanical conditions related to therapeutic patterns, and an institutional infrastructure with sufficient personnel and scheduling.

This study was conducted to examine the effects of an 8-week weight loss program, on body composition, body shape satisfaction, body shape esteem in 15 obese children. This program included nutritional education and regular physical fitness. After completion of this program, height and body weight increased slightly but body compositions changed. BMI, degree of obesity, and body fat levels dropped slightly, however these differences were not significant. After the 8-week program body weight increased from $63.61{\pm}8.80\;kg$ to $64.07{\pm}9.11\;kg$, degree of obesity and BMI decreased from $151.73{\pm}13.62%$, and $29.08{\pm}2.35$ to $146.60{\pm}12.92%$, and $28.57{\pm}2.26$, respectively, and the percentage of body fat decreased slightly from $42.70{\pm}4.87%$ to $41.46{\pm}4.88%$. There were slight changes in weight of body muscle and lean body mass from $19.62{\pm}3.48\;kg$ and $36.17{\pm}5.78\;kg$ to $20.30{\pm}3.64\;kg$ and $37.16{\pm}6.18\;kg$, respectively. LBM and amount of muscle were higher after this weight loss program. The body shape esteem score increased from $7.60{\pm}4.01$ to $9.00{\pm}6.20$. There was no significant difference in body shape satisfaction before and after the program, and the participants also wanted to be leaner. Finally, body weight, BMI, and body fat showed negative correlations to body shape esteem.

This study was attempted to identify the knowledge to breast-feeding and the performance of nursing activities for breast-feeding and to test 'how does the degree of knowledge to breast-feeding influence the nursing activities for breast-feeding?' The subjects were 180 nurses working in delivery rooms, nursery, obstetrics & pediatrics wards or OPD of obstetrics & gynecology of 8 general hospitals in Pusan as of August 3 through 13, 1996. The results are abstracted as follows. 1) Subject nurses' age, 25-29 was 45.6%(the major), education levels graduates from junior college were 95.0%, unmarried status was 62.2%, 76.5% of married nurses had children, 39.7% in-service education for Breast-Feeding, 33.7% did nursing activities for breast-feeding actively, the reason for inadequate activities for breast-feeding was 'too much other tasks.' 2) The degree of knowledge to breast-feeding ; mean score was 13.54, the degree of performance of nursing activities for breast-feeding : 92.38±20.93 points out of possible 145 points (3.19±.74 out of possible 5 points) moaned that it was a low level. 3) The hypothesis 'the nurses who have higher degrees of knowledge to breast-feeding will show higher degrees of performance of nursing activities for breast-feeding than the nurses who have lower degrees of knowledge to breast-feeding' was tested by t-test(t=-.01, P=.9888), but rejected because it turned out statistically not significant at the level of P<.05. Above results suggested the degrees of knowledge to breast-feeding and the degrees of performance of nursing activities for breast-feeding were generally low and the degree of knowledge didn't influence the nursing activities. Researchers believe that the education for breast-feeding by the nurses need to be performed systemically & practically and new method of breast-feeding education program need to include hospital managers as well as nurses related mothers and their family. In audition, researchers propose the introduction of &lactation specialist system&, for the specialist can change the attitude of feeding-mothers positively with their specialty and authority.

Purpose: This prospective study was designed to investigate the incidence of acute postoperative pain (APP) ${\geq}4$ and the risk factors of APP${\geq}$ for the first 48 hours after surgery. Methods: Data from 531 surgical patients were collected from November, 2009 to May, 2010. APP was assessed from the time of arrival at the Post Anesthetic Care Unit (PACU) to the end of the post-operative 48 hours. Risk factors of APP${\geq}$ were analyzed by logistic regression analysis. Results: The incidence of APP ${\geq}4$ was 58.8% for the first postoperative 4 hours; 33.5%, 24 hours; 11.1%, 48 hours. The score of pain was 5.55, the highest on arriving at PACU; 5.03 at postoperative 30 minutes; 4.03 at 1 hour; 3.96 at 4 hours; 2.76 at 24 hours; 1.44 at 48 hours Risk factors for APP ${\geq}4$ were females (Odds ratio [OR], 1.94; p=.013), general anesthesia (OR, 4.29; p<.001) and patient controlled analgesia (PCA) (OR, 2.83; p<.001) at 4 hours after operation; body mass index (BMI) ${\geq}25$ (OR, 1.80; p=.009), duration of surgery ${\geq}1$ hour (OR, 2.87; p=.037), general anesthesia (OR, 3.99; p<.001) and PCA (OR, 6.23; p<.001) at 24 hours; general anesthesia (OR, 3.53; p=.003) and PCA (OR, 3.01; p=.013) at 48 hours. Conclusion: Surgical patients with BMI ${\geq}25$, PCA and general anesthesia seem to have a higher incidence of pain ${\geq}4$ through the first postoperative 48 hours.
