  • Previous experiments have shown that aqueous sodium silicate ingested in drinking water may modify the gastrointestinal uptake and(or) tissue retention of certain trace elements, including heavy metals. The present experiment tested, with a mineral balance trial using sheep, the hypothesis that dietary silicic acid could modify uptake, retention and(or) biological effects of dietary Cd. Twenty-four wethers were fed a fibrous diet of ground alfalfa hay and cottonseed hulls to which either 0 or 150 ppm Cd was added as $CdCl_2$ and 0, .5 or 1% silicic acid (as dry matter of the diet). Body weight, feed intake, excretion of urine (volume) and feces (weight), digestibility of dry and organic matter, retention of nitrogen, and packed cell volumes of blood were not affected by either Cd or silicic acid (P<.10). Cadmium decreased (P<.05) Ca retention and increased (P<.01) Mg retention. Silicic acid decreased (P<.05) K retention. Silicic acid failed (P<.01) to modify the retention of added dietary Cd. Body retention of K, Mn and Ni in response to silicic acid varied with Cd levels. If Cd is interfering with mineral retention, silicic acid may be effective in preventing this interference.

  • Implant-supported overdenture is known as a useful appliance, instead of using the conventional complete denture, for better retention and stability. In this study 4 types of materials such as, gold bar/plastic clip(group AuP), gold bar/metal clip(group AuM), palladium bar/plastic clip(group PdP), and palladium bar/metal clip (group PdM) were used to evaluate the retention forces according the type of clips and alloys used for bar fabrication, in the Hader bar system. Repeated insertions and removals of overdenture were conducted in each group. and the retention forces were measured and compared the data of each group according to the number of insertion and removal. The obtained results were as follows, 1. In the comparison of retention forces according to type of bar-clip, retention was increased in the order of group AuM, PdM, PdP AuP. and the retention force of group AuM was significantly increased compared with those of others (p<0.05). 2. In the comparison of retention forces according to the number of insertion, only group PdP showed significant decrease in retention(p<0.05). 3. In the comparison of retention forces according to the type of bar and clip. there was no significant difference in the type of bar, but the retention of plastic clip was significantly higher than that of metal clip when Au bar was used(p<0.05). 4. In the observation of the bar surface, group AuM using Au bar and metal clip showed the most scratches among bar groups.

  • Using of geosynthetics with linear materials(sand, gravel, clay soil) is rapidly increased in landfill. With geosynthetics, geotextiles often expose to solar radiation(Ultraviolet) on long terms during the installation. In this paper, the results will represent the strength retention rate and tensile retention rate of geotextiles between outdoor exposed and protected by 15cm thickness of soil. As a result of cumulating solar radiation in geotextiles was increased, the strength retentions rate of P.P(500g/$m^2$), P.P(700g/$m^2$) and P.P(1000g/$m^2$) were decreased and the lower weight of unit area of geotextiles, the faster decrease of strength retention rate. P.E.T(600g/$m^2$) was showed a distinctive trend that the strength retention rate increased. The tensile retention rate of tested geotextiles was decreased during the simulation. However, the strength and tensile retention rate of geotextiles covered by soil had changed insignificantly. Therefore, it can surmise that the soil covering will help geotextiles to be protected from UV effecting

  • Objectives: The purpose of this study was to verify the relationships among nursing work environment, job satisfaction, organizational commitment, and retention intention, as well as to clarify the factors that affect nurses' retention intention. Methods: The study included 163 nurses working in three general hospitals located in B city. Data were collected by a survey using self-administrated questionnaire and analyzed using the SPSS software. Results: The participants expressed a moderate level of retention intention. There were significant differences in retention intention by income (t=-2.13, p=.034) and intention to work (F=9.86, p=.001). The factors influencing retention intention were organizational commitment (${\beta}=.28$, p=.001), job satisfaction (${\beta}=.25$, p=.001), nursing work environment (${\beta}=.23$, p=.004), plan to work period (${\beta}=.13$, p=.027). These factors explained 55.3% of retention intention (F=41.079, p<.001). Conclusions: The findings showed that nursing administrators should develope programs that promote internal satisfaction for new nurses and strive to improve the human and physical aspects of the nursing work environment for career nurses.

  • Three crossbred gilts weighing $61{\pm}2kg$ ($mean{\pm}SD$) and three gilts weighing $52{\pm}3kg $ on the day before the first treatment began (d -1) were used for each of two experiments (Exp. 1 and Exp. 2), respectively. In Exp. 1, all pigs were fed the experimental diet (CP 19%) from d -7 to the end of study (d 21) to verify that nitrogen retention is constant during the 21 -d period. In Exp. 2, pigs were fed the control diet (CP 15.5 %) from d -7 to d 8 and then the low-lysine diet from d 9 to d 16 in order to determine how rapidly dietary changes in amino acid composition results in a new equilibrium for nitrogen metabolism. The amount of urine nitrogen loss was not different over 21 days (p > 0.10). Rates of nitrogen retention were not different among pigs (p > 0.10) nor over time (p > 0.10). Average nitrogen retention during the period was 1.00 g/kg $BW^{0.75}$ per day. The apparent biological value was 41%, which did not change over the 3-week period (p > 0.10). The overall efficiency of nitrogen use for nitrogen retention was 35% (Exp. 1). The amount of nitrogen loss in urine and the efficiency of nitrogen utilization for nitrogen gain reached a new equilibrium within 2 to 3 d after the diet was changed. The low-lysine diet resulted in a 20% increase of nitrogen loss in urine (p < 0.001) and a 9% decline in efficiency of nitrogen use for nitrogen retention (p < 0.001). Nitrogen retention while the pigs were fed the control diet was also higher than the retention when pigs were fed the low lysine diet (p < 0.001). The efficiency of nitrogen use for nitrogen retention in pigs fed the control diet was 57% (Exp. 2), which was higher (p < 0.001) than that from pigs fed the low-lysine diets (52%).

Methods: The retention force was measured by being pulled at the speed of 1mm/min after being combined with zirconia block and abutment using Temp-BOND of Kerr. The experiment was done at the research lab of OSTEM in Busan by useing UNIVERSAL TESTING MACHINE on March 3rd, 2010. Results: After analysing the total height and the retention force, p-value had minor difference by 0.01 statistically. Namely, 3mm, 4mm, 5mm had the retention force difference and we could see retention force difference on 3mm and 5mm at the post test. After analyzing how to regulate the height and retention force, p-value had minor difference by 0.000 statistically. Namely, 1mm and 2mm had the retention difference and we could see that 1mm and 2mm with the total height had retention difference. After analyzing the retention force based on the size, p-value had minor retention force difference by 0.000 statistically. Namely, 7 different size had retention force difference and we could see the size 21.9mm, 32.9mm, 32.9mm, 38.4mm, 48.9mm and 54.9mm had retention force difference. Conclusion: Namely 9 different design group had retention difference and we could see that 9 design group with 5.6.7.8 design group and 9 design group with 1.2.3.4. design group had retention force.

  • This study was to investigate the relationship of job stress, health status, and health promotion behavior, retention intention and to identify the influencing factors on retention intention of nurse in Emergency Room(ER). The subjects were 155 ER nurses working at 15 general hospital in Gwangju, Korea. The data were collected from October 15, 2020 to November 3, 2020. The result, there were negative correlation between job stress and health promotion behavior(r=-0.310, p=<.000), between job stress and retention intention(r=-0.220, p=.006), between health status, and health promotion behavior(r=-0.448, p=<.000), between health status and retention intention(r=-0.296, p=<.000), but there were positive correlation between job stress and health status(r=0.368, p=<.000), between health promotion behavior and retention intention(r=0.229, p=.004). Factors influencing retention intention were fatige and health status with R2 value 22.7%. Considering these results, it seems that important factors determining the retention intention of nurses in ER are Spiritual health status, heavy workload due to job stress, fatigue and social health status by nurse. Therefore, in order to increase the retention intention of nurse in ER, it is a need for strategies to improve the working environment and develop programs to reduce job stress and fatigue through work adjustment, and to maintain and promote health.

  • Purpose: The present study examined the psycho-emotional factors that affect the retention intention among advanced beginner-stage nurses. Methods: A cross-sectional study was conducted using a convenience sample of 118 nurses with a work experience of at least one to three years of work experience in a university hospital in Suwon, Korea. Structured questionnaires were used to assess retention intention, emotional labor, and resilience. Multiple regression analysis was used to examine factors affecting retention intention. Results: Retention intention had a moderate mean score (4.75 out of 8). Factors influencing participants' retention intention were founded in the order of resilience (β=.29, p<.001) and emotional labor (β=-.20, p=.011) after adjusting nursing satisfaction as a covariate. The multiple regression model accounted for 42% of the variance in retention intention (p<.001). Conclusion: Resilience and emotional labor may be primary factors influencing retention intention of advanced beginner-stage nurses. Therefore, this study finding suggested that psycho-emotional factors such as emotional labor and resilience should be considered while designing programs to increase nurses' retention intention.

  • Purpose: This study was designed to examine effects of sense of calling, job satisfaction and organizational commitment on retention intention in nurses who are at the advanced beginner-stage. Methods: Participants were 199 nurses with 13 to 36 months' clinical career at hospital located in Busan, Korea. Data were analyzed using descriptive statistics, independent t-test, one-way ANOVA, Scheffe test, Pearson correlation, and Multiple regression. Results: Retention intention correlated positively with sense of calling (r=.43, p<.001), job satisfaction (r=.31, p<.001) and organizational commitment (r=.31, p<.001). Factors affecting the participants' retention intention were found to be statistically significant (F=21.96, p<.001). Total factor score accounted for 24.1% of retention intention. Out of the related factors, the most influential factor was 'goals/meaning', belonging to the sub-areas of the sense of calling and explaining 18.2% of retention intention, followed by organizational commitment and average monthly income in that order. Conclusion: The results of this study suggest a need to develop a management program that helps promote retention intention for nurses at the advanced beginner-stage by both improving their monthly income and outside conditions and, more importantly, raising their sense of calling, especially in association with the goals/meaning of their life.
