Purpose: The purpose of this study was to investigate the relationships between resilience, job satisfaction, and job stress among nurses working at general hospitals. Methods: This study was a descriptive study using a questionnaire. The resilience scale, satisfaction scale and job stress scale were used. The data from 194 infection control nurses, who work for below 3 years at general hospitals, were collected from March 2 to September 30, 2017. Data were analyzed using SPSS 22.0 Win program. Results: In this study, job stress showed significant negative correlations with resilience (r=-.14, p=.043) and job satisfaction (r=-.50, p<.001). However, there was a significant positive correlation with infection control experience (r=.32, p<.001). Also, the level of job requirement stress and job autonomy stress scored higher than other sub-dimension of job stress. Job satisfaction was the most significant predictor (β=-.43, p<.001) in job stress. Conclusion: The findings of this study suggest that systematic training courses and education programs for new infection control nurses should be developed to decrease nurses' job stress and increase their resilience. Holding this program can help reduce nursing job stress and help to adapt individuals to existing changes.

The purpose of this study was to estimate the microbial quality of some raw vegetables, and suggest a safer method for their sanitization and pre-preparation in foodservice operations. Baechu-geotjeori was monitored from the ingredient to the final product, during different holding temperature. Three sanitization methods were performed during the pre-preparation (tap water, chlorine water and electrolyzed water). The largest reduction in the microbial counts was shown with the electrolyzed water pre-preparation (after treatment; the total plate counts decreased to 3.34-4.06 Log CFU/g, coliform counts decreased to 1.40-1.45 CFU/g). Prior to immersion in the chlorine water, washing was first peformed to see if the was a larger effective reduction in the microbial counts.

Purpose: Purpose of this study was to identify the effect of structured information on immediate preoperative anxiety and uncertainty for women undergoing total laparoscopic hysterectomy. Methods: Sixty women who were admitted for total laparoscopic hysterectomy were recruited at a university hospital in Gyeonggi-do from June to October 2014. Thirty women were assigned to either the experimental or the control group. Women in the experimental group were provided structured information, which consisted of visual and auditory materials about surgical preparation and process, practical experience on devices such as IV-PCA pump and Inspiro-meter and actual experience on route to go to the operating room. State-anxiety, uncertainty, and blood pressure and pulse rate as biological indicators were measured before and after the intervention to examine the effect. Results: Significant group differences were found on state anxiety, uncertainty, including ambiguity, inconsistency, and unpredictability at the holding area. There was a significant difference on pulse rate in the operating room between the two groups. Conclusion: Findings demonstrated that the structured information provided for women undergoing laparoscopic hysterectomy preoperatively was effective on immediate preoperative anxiety and uncertainty. Nurses may contribute to decreasing patients' anxiety and uncertainty by utilizing this structured information preoperatively.

Objectives : The purpose of this study was to investigate the possible differences in elementary schools jointed to fluoride mouth rinse plans in health centers. Methods : Students from the third to sixth grades filled out the questionnaires. Data were analyzed by the statistical package SPSS 12.0. Results : The rate of a personal toothbrush holding and toothbrushing after lunch were higher in those who rinsed their mouths with fluoride than those who did not.(p<0.05). Toothbrushing by the rolling method was more prevailing in the students who rinsed their mouths with fluoride(57.0%) and having regular dental checkup(p<0.05) than in those who did not(39.8%). Conclusions : The students who had rinsed their mouths with fluoride showed the good oral health behavior. Continuing good quality of oral health care education must be provided to the students by professional dental hygienists.

The present study covers an integrated simulation method to evaluate optical performance of an aspheric plastic lens by connecting a finite element (FE) analysis of injection molding with a ray tracing simulation. Traditional ray tracing methods have based on the assumption that the optical properties of a lens are homogeneous throughout the entire volume. This assumption is to a certain extent unrealistic for injection-molded plastic lenses because material properties vary at every point due to the injection molding effects. To take into account the effects of the inhomogeneous optical properties of the molded lens, a new.ay tracing scheme is proposed in conjunction with a FE analysis of the injection molding. A numerical scheme is developed to calculate ray paths on every element layer with more realistic information of the refractive indices which can be obtained through the FE analysis. This information is then used to calculate the ray paths based on the FE mesh of which nodal points have unique index values. The proposed tracing scheme is implemented on the tracing of an aspheric lens, and its validity is ascertained through experimental verification.

In dental roentgenograph it is of mutual benefit to the patient and the dentist to use the minimum amount of radiation capable of producing roentgenograms with maximum interprtive informations. Recent increases in the number of diagnostic x-ray examinations made in this country have caused attention to be paid to the quantity of radiation delivered to the population and operator. The purposes of this study was to assess the quality of dental x-ray units, the amount of films, the average processing procedures and the radiation protection methods in korea. The results were as following: 1. Most of radiation generating system were used in low voltage such as 60Kvp, 10㎃. 2. High sensitivity films such as 'D' group of Kodak or Rinn were mainly used and average 14.7 films used per weeks. 3. Some dentists practiced visual processing technic in simple dark room, and others used instant films. 4. 68.26% of patient held the film themselves, but 27.30% were assisted by dentists film holding. 5. In radiation protection method, 7.85% of dentists had protection equipments such as protective barrier, 2.73% wore protective apron, 27.9% made it a rules to avoid beam, and 7.51% used to maintain a distance from the radiation source.

Indoor environments are usually less than optimal for the growth of ferns, especially in regards to the water condition. These studies were performed to investigate responses involved in causing growth of ferns and presume management plan against the water deficit under indoor conditions. The effect of air humidity and soil moisture on the ferns was examined in Adiantume raddianum and Selaginella kraussiana. Results of experiments are as follows; 1. Under a low humidity condition, having a 25-50% RH. ornamental value of ferns decreased much more than under a 90% RH. Under a low soil moisture, such as sand treatment, ornamental value of ferns also decreased. 2. Leaf chlorophyll content, water content and stomata situations increased as air humidity and soil moisture went up. 3. Even if air humidity and soil water were not enough for ferns growth, the extending of irrigation cycle was helpful. 4. Under extremely low air humidity conditions, some water management, namely, using water holding soil or extending of irrigation cycle was desirable. Other methods of increasing air humidity, including water instruments such as ornamental pools, waterfalls, or fountains, grouping plants together were also helpful. But spraying water on leaves increased injury to ferns growth because of excess evaporation from the leaves. Though these studies, we learn that ferns are susceptible to water condition such as air humidity, soil water and water management. If other environmental factos are maintained with optimal conditions, water condition plays an important role in ferns growth in indoor environments.

The research postulates the conceptualization of talent in the Vietnamese banking sector via examining the factors pertaining to the concept of talent and talent management (TM) in the sector. This study applied qualitative research methods. A total of 20 managers and directors of ten banks (three public, four private and three foreign banks) were recruited for semi-structured interviews. The findings revealed that a combination of interconnected soft skills, learning ability, flexibility, technology adaptability, integrity and risk management skills contributes to talent identification. Managers in some private banks construed talent to be commensurate with high performance and high potential, whereas managers in public banks and foreign banks mainly relied on performance results in talent recognition. Moreover, talented employees holding sales-related jobs are given the most attention by management in the studied banks. Regarding practical implications, the banking community and practitioners' focus should be imparted to soft skills development and integrity control in order to foster employee performance and attitudes. Attention should be paid not only to sales positions, but also to other positions within the bank. This study is one of a few which explores talent concepts and TM approaches in the banking sector in general and Vietnamese banking field in particular.

Quality characteristics of frozen cylindrical pork loin were evaluated following different tempering methods: 27.12 MHz curved-electrode radio frequency (RF) at 1000 and 1500 W, and forced-air convection (FC) or water immersion (WI) at $4^{\circ}C$ and $20^{\circ}C$. The developed RF tempering system with the newly designed curved-electrode achieved relatively uniform tempering compared to a parallel-plate RF system. FC tempering at $4^{\circ}C$ was the most time-consuming process, whereas 1500 W RF was the shortest. Pork sample drip loss, water holding capacity, color, and microbiological quality declined after WI tempering at $20^{\circ}C$. Conversely, RF tempering yielded minimal sample changes in drip loss, microstructure, color, and total aerobic bacteria counts, along with relatively uniform internal sample temperature distributions compared to those of the other tempering treatments. These results indicate that curved-electrode RF tempering could be used to provide rapid defrosting with minimal quality deterioration of cylindrical frozen meat block products.
