Purpose: This study aimed to identify the mediating effects of career motivation and job-esteem and the effect of the nursing work environment on intention to stay among hospital nurses. Methods: Data were collected from 289 nurses working at an advanced general hospital. The research model design was based on the PROCESS macro proposed by Hayes and analyzed using SPSS 24.0 program. Results: The results showed a positive correlation between intention to stay and nursing work environment (r = .19, p = .001), career motivation (r = .34, p < .001), and job-esteem (r = .37, p < .001). Nursing work environment (B = 0.34 [.09~.59]) and job-esteem (B = 0.27 [.04~.49]) had a direct effect on intention to stay. There was a two-mediator sereal mediation effect of career motivation and job-esteem. The nursing work environment showed a significant effect on the intention to stay among hospital nurses through career motivation and job-esteem. Conclusion: In order to increase the retention rate of hospital nurses, it is suggested that government and medical institutions provide multifaceted support that can increase nurses' motivation for career development and recognition of the nursing profession through improvement of the nursing work environment.

Purpose - This study aims to empirically identify the quantitative effects of work from home (WFH) on employee productivity using field data. Design/methodology/approach - Based on large-scale field data from a South Korean company which introduced the WFH arrangement in 2020, we conducted fixed effect and moderating effect analyses using individual-level panel data over sixty-three weeks. Findings - The empirical analysis generated several findings. It was found that overall, WFH has a positive effect on productivity. However, the productivity impact of WFH was found to vary depending on task characteristics. Specifically, WFH led to over 20% increase in productivity for simple and repetitive tasks. On the other hand, no significant productivity impact was observed for professional and knowledge-based tasks. Research implications or Originality - As the first study based on field data from South Korea, this study offers convincing causal evidence of the moderating impact of task characteristics on the relationship between WFH and productivity. Further, the above findings provide managers with practical insights concerning their work arrangement decisions.

Coast guard organization has very different working environment with other general administrative organizations or police organizations. Because they are charging various coastal crimes and safeties by using war vessel at ocean, it was expected that in case of coast guard officers, the impact on organization commitment for each trust factor within organization has the differentiation with other administrative organizations. Core of results by conducting positive research is as following: It is indicated that for coast guard officer, organization trust factor most strongly impacts on organization commitment, and of social trust factors, colleague trust factor more impacts relatively than boss trust factor. Then, when searching the difference of trust factor recognition depending on population sociological properties of coast guard officers, it is indicated that the one having the experience of working at war vessel has more trust to its colleagues than the one having not and executives more trust their boss than non-executives. The reason why the trust to colleague is higher than to boss is recognized that it is caused from deep relationship with colleagues who work and live together when considering working conditions of security vessel.

This survey was conducted to evaluate with 457 health professionals from July, 1999 to September, 1999 the awareness of and satisfaction with the nutrition labeling system in Korea and to determine a desirable labeling system. Professors of food and nutrition and nutrition researchers in the food industry had the hightest scores on awareness of the nutrition labeling system(75.6% and 73.4%, respectively), which was significantly different from each other by occupation(p < 0.01). Frequently checked labeling information were expiration date, production date, price, and company respectively. Special nutrient food producers(56.9%), dietitians(49.3%), nurses(48.1%), researchers(42.3%) answered moderately on satisfaction with nutrition information for products, which was statistically significant(p < 0.01). This suggests that health professionals were unsatisfied with the present nutrition labeling system. In nutrition focusing statements, nutrient content claims, health claims, and working periods were significantly related with nutrition focusing statements and health claims, but not with nutrient content claims : the subject who had been working for more than 10 years and less than 5 years had positive thoughts or those matters while the subjects whose working periods were between 10 and 5 years had the lowest score. The most desirable labeling units were serving size(65.1%). Ninety two percent of the subjects wanted absolute nutrient contents in food and their percentage of the KRDA. Eight nine percent of health professionals agreed that the health claims should be used only with scientific approval by the government or food research institutions. Only 4.4% of subjects were satisfied with current regulations of health claims(p < 0.001). More studies regarding labeling units, their range and nutrient reference values are needed. The opinions of health professionals in nutrition labeling system should discussed to establish a desirable nutrition labeling system.

Transgenic rice cells using RAmy3D promoter can provide high productivity, and the production of recombinant protein is induced by sugar starvation. In this system, productivity was reduced during the scale-up processes. To ensure the influences of shear stress and oxygen transfer rate, working volume and mixing performances were investigated under various agitation speeds and working volumes. In addition, inoculation methods including suspended cells and filtered cells were compared. Working volumes and shaking speeds were 300, 450 mL and 80, 120 rpm, respectively. Hydrodynamic environment of each condition was measured numerically like mixing time and $k_La$. Good mixing performance and high shear stress were measured at high agitation speed and low volume. The highest level of hCTLA4Ig was 30.7 mg/L at 120 rpm, 300 mL. When conditioned medium was used for inoculation, increased cell growth was noticed during the day 0~4 and decreased slower than filtered cells. Compared with filtered cells, the maximum hCTLA4Ig level reached 37.8 mg/L at 120 rpm, 300 mL and lower protease activity level was observed. In conclusion mixing performance is critical factor for productivity and conditioned medium can have a positive effect on damaged cells caused by hydrodynamic shear stress.

Liquid ejectors are widely used as marine pumps, inducer stage for the boiler feed water pump, boiler recirculating pump, cooling water recirculating pump in boiling water type nuclear reactor and a deep well pump, because of their high working confidence and simplicity. Furthermore, it requires only a modest net positive suction head for cavitation-free operation and it can be installed in remote location from mechanical power source. It is not easy to presume the friction losses, because it is complicately affected by area ratio, flowrate ratio, nozzle spacing, throat length, shape of liquid ejector and so on. Therefore, the optimization of liquid ejector design is still dependent, to a large extent, on the experimental results and empirical procedures. On the design of the liquid ejector, the area ratio and the nondimensional throat length are the most important design factors among the mentioned above. In this experiment, the effects of the area ratio and the nondimensional throat length to ejector efficiency are carried out systematically by the combination of 4 kinds of motive nozzle and 2 kinds of throat length. In this paper, the present experimental results are compared with the calculated ones by the previous computer aided design program based on one dimensional flow equation. And also, an empirical equation for the working limit of liquid ejector is reported.

Objective: The purpose of this study were to: (1) describe the individual characteristics, perceived health status, body image, and health promoting behaviors of staff nurses working in a metropolitan hospital and (2) determine the relationship of perceived health status, body image, and health promoting behaviors. Methods: Data were collected from 311 staff nurses working at one of university affiliated hospitals using a self-administered questionnaire for perceived health status(SF 36 V2), body image(BAQ), and health promoting behaviors (HPLP-II) and using the report of year 2002 employee physical check-up results for health related characteristics. Results: Most of nurses were within the normal range of BMI, total cholesterol, and liver enzymes but 42.2% had systolic BP above 120mmHg and 37.3% hemoglobin below 12g/dL. Although 96.4% of BMI score indicated 'underweight' or 'normal', 'feeling fat' showed the highest. Among health promoting behaviors the most frequently reported one was spiritual growth and the least one was engagement in physical activity. In the correlational analysis, health promoting behaviors had the positive relationships with perceived health status, vitality, mental health, attractiveness, strength and fitness (p=.000 - .004). Conclusion: These findings provide information that is relevant in designing interventions to enhance health promoting behaviors among nurses working in a hospital.
