  • This study evaluated the moral sensitivity, self-assertiveness, ethical decision-making confidence and their correlations, and the factors that influence ethical decision-making confidence among nurses working in a long-term care hospital. Overall, 149 nurses working in a long-term care hospital in G Province were evaluated. The date was collected from November 30 2019 to December 18, 2019 and analyzed using SPSS/WIN 21.0 program. The mean of moral sensitivity among nurses was 4.94, the mean of self-assertiveness was 3.17 and the mean of ethical decision-making confidence was 3.49. The self-assertiveness will, according to the general characteristics, was significantly different according to experienced moral distress, and there was a significant difference in the degree of ethical decision-making confidence according to social positions and experience of ethical education. There were positive correlations between the ethical decision-making confidence and moral sensitivity (r=.382, p<.001) and self-assertiveness (r=.224, p<.01). Regression analysis revealed that the factors that significantly influenced ethical decision-making confidence were moral sensitivity, self-assertiveness and ethical education during nursing practice, which explained 25.0% of variance in ethical decision-making confidence. Therefore, to improve ethical decision-making confidence of nurses, programs should be developed that improve moral sensitivity and self-assertiveness by promoting ethical education.

  • Purpose: Some recent literatures report that it is possible to recover defected areas caused by enucleation of relatively large jaw cysts without using bone grafts. The aim was to find out whether spontaneous recovery of defected area with time occurred and what the contributing factors were. Materials and methods: In total, 194 patients were considered as patients. Out of these 194 patients, 74 patients who had no wound dehiscence and who were available for follow-up studies were selected. They were classified into two groups according to the size of radiolucent area in the preoperative panoramic radiographs: in one group, it was larger than $3{\times}4cm$, while in the other group, it was smaller than $3{\times}4cm$. Follow-up panoramic radiographs were taken immediately after the surgery, then after 3, 6, 9 and 12 months. On those radiographs, changes in size and density of the defected areas were observed using the Gray-level histogram of Adobe photoshop v7.0. Correlation between bone regeneration and factors such as the type and size of the cysts, age, sex, site of the cysts and systemic disease was evaluated using the General repeated measure and Mann-Whitney Test. Results: Analyses of panoramic radiographs showed that the recovery of radiopacity after 12 months was more than 97% on average in defected areas that were smaller than $3{\times}4cm$. in the defected areas that were larger than $3{\times}4cm$, considerable portion showed recovery of radiopacity. No statistically significant change was observed in bone density according to the type of cysts. Young patients under 20 years of age with highly active metabolism presented more significant bone regeneration than patients over 20 years of age. Bone regeneration was more hampered in patients who had medical disease, compared with patients who didn’t have any medical problem. No statistically significant change was seen in bone density according to sex. Changes in bone density according to the site of cysts such as maxilla, mandible, anterior or posterior region were not considered to be significant. Conclusion: Analyses of panoramic radiographs suggest that in approximately 12 months after the enucleation of cysts, clinically acceptable spontaneous bone regeneration can be observed even though normal bone graft procedures have not been applied.

  • This study was conducted to identify dietitians' position and role by assessing the present condition on management of human resources in contracted foodservice management company. Questionnaires were distributed to 79 contracted companies (eight large-size, 48 mid-size, 23 small-size companies) from March to May in 2002. Statistical analysis was performed with SPSSwin (version 8.0). The data were analyzed in group comparisons using frequencies and percentage for every item in the questionnaires, $x^2$-test, and oneway ANOVA. About eighty-five percent of contracted foodservice companies employed the new dietitians as full time employees, and seventy-five percent of them were promoted the dietitians by evaluation after a given period of time. As a starting payment for university graduates, large-size companies payed an average of 16,260,000 won/year, which was significantly higher (p<0.01) than those of mid-sized (11,320,000 won/year) and small-sized companies (11,620,000 won/year). The mean lengths of dietitians' service were 33.5 months in large-size companies, 26.5 months in mid-sized companies, 26.0 months in small-sized companies. It was less than 3 years in all companies (avg. 26.9 months). Fifty-four companies (68.4%) employed dietitians in each foodservice contract, whereas 25 companies didn't employ dietitians. The ratios of dietitians out of employees in each department of the companies were 42.6% in the department of contracted foodservice management, 19.9% in the department of menu development, 18.1% in the department of food safety, 8.7% in the department of distribution and purchase, 4.2% in the department of business, and 3.9% in the department of customer satisfaction.

  • Objectives : The purpose of this study is to prove the effect and mechanism of Gamikyejakjimogawusul-tang(GKHA) herbal acupuncture on induced rheumatoid arthritis model of DBA/1 mice. Methods : We check effect of GKHA extract on the AST, ALT, Creatinine, BUN of serum and cell viability of GK extract in RAW 264.7 cells to test the stability of this study. In vitro, we measure total phenol contents, total flavonoid contents, DPPH free radical scavenging activity, ABTS cation radical scavenging activity of Gamikyejakjimogawusul-tang, effect of GK extract on ROS(Reactive Ooxygen Species) production to estimate a anti-oxidant capacity, and we also measure effect of GK extract on NO (Nitric Oxid), IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF production in RAW 264.7 cells to estimate a anti-inflammatory efficacy. In vivo, we compare a rheumatoid arthritis manifestation between control and experimental group and estimate a AI. Then we check effect of GKHA on the level of WBC, neutrophil, lympocyte, monocyte in the blood to see the effect of immune cells in blood. In addition we measure effect of GKHA on the level of hs-CRP, IgM, IgG, IL-$1{\beta}$, IL-6, IL-17, IL-21, TNF-${\alpha}$, MCP-1, GM-CSF in serum. We observe effects of GKHA on imaging of cartilage degeneration using micro CT-arthrography in paw hind. And we calculate effects of GKHA that reduced BV ratio, BS/BV ratio using 3D Micro-CT. Lastly we observe effects of GKHA histopathologic examination analysis. Results : 1. The toxicity on liver and kidney was disregardable and the cytotoxicity against RAW 264.7 cells was also disregardable. 1. Total phenol contents and total flavonoid contents in GK extract were in high level. 2. DPPH free radical scavenging activity and ABTS cation radical scavenging activity were increased according to concentration of GK extract 3. ROS production was significantly decreased in GK extract (at 10, $100{\mu}g/ml$). 4. NO, IL-6, TNF-${\alpha}$, MCP-1 production were significantly decreased in GK extract(at 10, $100{\mu}g/ml$). IL-17, GM-CSF production were significantly decreased in GK extract(at 1, 10, $100{\mu}g/ml$). IL-$1{\beta}$, IL-21 production were also decreased but there was no statistical significance. 5. 25x observation after H&E and M-T staining, infiltration of immune cells and subsidence of the cartilage and damage to the synovial cells were decreased. Conclusions : This study showed that GKHA extract had anti-oxidant capacity, anti-inflammatory efficacy. GKHA extract also had inhibiting effect on the process of rheumatoid arthritis and can protect joint and cartilage. So we expect that GKHA extract can be a meaningful treatment to rheumatoid arthritis patients.

  • ATMS calculates section travel time using two-way communication system called DSRC(Dedicated Short Range Communications) which collects data of RSE (Road Side Equipment) and Hi-pass OBU (On-board Unit). Travel time estimation in urban area involves uncertainty due to the interrupted flow. This study not only analyzed real-time data but also considered pattern data. Baek-Je-Ro street in Jeon-Ju city was selected as a test site. Existing algorithm was utilized for data filtering and pattern data building. Analysis results repoted that travel time estimation with 20% of real-time data and 80% of pattern data mixture gave minimum average difference of 37.5 seconds compare to the real travel time at the 5% significant level. Results of this study recommend usage of intermixture between real time data and pattern data to minimize error for travel time estimation in urban area.
