  • This study aims to find out ways of improving life satisfaction of rural elderly by investigating their work and leisure activity, two significant axis of the life in later life. For this purpose, researchers and one assistant researcher visited house, senior citizen's center and health center, in order to have interviews with senior citizen above 65, who are currently working in the field. The summary of the research findings are as follows; First, the average size of the farm land which each senior citizen works on is $9,237.92m^2$ and they mostly work for economic reason. During farming season, they work on average 8.62 hour per day. As primary reasons for why farming work is difficult, "insufficient income" was picked. In fact, the average annual income senior citizens earn from farming is about 15.4 million won. 49.1% of sample senior citizens work both on watered farm and farm, and they are engaged in farming 48.82 years on average, showing that most of their lives have been spent on farming. In spite of these difficulties, most senior citizens showed high intention to continue farming work further. Second, senior citizens turn out to spend their leisure time mostly on public leisure activities such as watching TV, hearing radio and gatherings with families, relatives. However, individual activities such as meditation, yoga, drawing and calligraphy turn out to be low because they require foundations to enjoy. Third, senior citizen in rural areas were divided into four groups by farm work and leisure activity: group separated from work and leisure activity(27.09%), group centered to leisure activity(24.42%), group centered to work(23.75%), and group integrated work and leisure activity(23.75%). Fourth, the groups were different depending on demographic characteristics. Namely, male senior citizen, higher educational level, living in elderly couple households, and satisfied with their economic level belonged to the group integrated work and leisure activity. But senior citizen aged above 65 years old and working for their livelihood belonged to the group centered to work, and most of female and senior citizen aged above 80 years old belonged to the group separated from work and leisure activity. Finally, as the result of analysis of differences in life satisfaction according to farm work and leisure activity of senior citizen in rural areas, the group integrated work and leisure activity, and group centered to leisure activity were higher in life satisfaction than the group separated from work and leisure activity, and group centered to work. The above result indicates that life satisfaction of senior citizen depends upon leisure activity rather than work.

  • We examined the relationship among riboflavin intake, work activity, erythrocyte glutathione reductase activity coefficient(EGR AC)and urinary riboflavin excretion. We also attempted to determine factors affecting seasonal riboflavin status of rural women. All information about nutrient intake, work activity and riboflavin biochemical status was repeatly collected in three seasons ; farming season(June), harvest season(October), nonfarming season(February). EGR AC was negatively correlated with riboflavin intake(P<0.005) and positively correlated with the duration(min) of farming activity(P<0.005) and the percentage of lean body mass(LBM) (%) representing long term physical activity(P<0.05) in harvestseason. Urinary riboflavin excretion was positively correlated with the ratio of riboflavin intake to 1,000kcal of energy expenditure (P<0.05) in farming season and negatively correlated with the duration(min) of farming activity (P<0.05) and crude nitrogen balance(P<0.005) in harvest season. It appeared that EGR AC seems to increase and urinary riboflavin excretion seems to decrease as work activity increase. Therefore work activity would be expected to deteriorate riboflavin status. Multiple regression analysis of variables showed that in general EGR AC was affected by riboflavin and energy intakes, energy expenditure, energy balance, the duration(min) of farming activity, LBM (%). Urinary riboflavin excretion was affected by riboflavin and protein intakes, LBM(kg) and crude nitrogen balance. Crude nitrogen balance affected urinary riboflavin excretion in all seasons. The result indicated that work activity as well as nutrient intake seemed to affect riboflavin status, especially EGR AC was affected preferentially be work activity in all seasons.

  • Although many research efforts have been conducted to address the effect of crew members' work skills (e.g., technical and planning skills) on work performance (e.g., work duration and quality) in construction projects, the relationship between skill and performance has generated a great deal of controversy in the field of management (Inkpen and Crossan 1995). This controversy can lead to under- or over-estimations of the overall project schedule, and can make it difficult for project managers to implement appropriate managerial policies for enhancing project performance. To address this issue, the following aspects need to be considered: (a) work performances are determined not only by individual-level work skill but also by the group-level work skill affected by work team members, each member's role, and any working behavior pattern; (b) work planning has significant effects on to what extent work skill enhances performance; and (c) different types of activities in construction require different types of work, skill, and team composition. This research, therefore, develops a system dynamics (SD) model to analyze the effects of both individual-and group-level (i.e., multi-level) skill on performances by utilizing the advantages of SD in capturing a feedback process and state changes, especially in human factors (e.g., attitude, ability, and behavior). The model incorporates: (a) a multi-level skill evolution and relevant behavior development mechanism within a work group; (b) the interaction among work planning, a crew's skill-learning, skill manifestation, and performances; and (c) the different work characteristics of each activity. This model can be utilized to implement appropriate work planning (e.g., work scope and work schedule) and crew management policies (e.g., work team composition and decision of each worker's role) with an awareness of crew's skill and work performance. Understanding the different characteristics of each activity can also support project managers in applying strategic work planning and crew management for a corresponding activity, which may enhance each activity's performance, as well as the overall project performance.

  • This study examined the relations of educational level and life-style behaviors to the obesity. A total of 507 male adults aged 30 - 50 years completed the self-reported questionnaires. Educational level was used for measuring socioeconomic status. Activity at work, leisure-time activity and TV watching were measured for life-style behaviors related to physical activity, and some demographic and family history of disease as well. Subjects were categorized as obese when BMI was equal to or over 25kg/$m^2$, in which 19.7% resulted obesity. Using multivariate logistic regression, the association between the measured factors and obesity was assessed. The odds ratios (OR) for risk of obesity did not differ with either age or monthly income. Subjects who completed high school (OR = 0.36; 95% CI = 0.20 - 0.66) or university (OR = 0.34; 95% CI = 0.16 - 0.71) had lower risk of obesity than those with education below middle school. Those with moderate activity level at work (OR = 0.41; 95% CI = 0.24 - 0.72) showed lower risk of obesity than in inactive ones. The subjects watching TV more than 3.5 hr/day presented higher risk of obesity (OR = 2.46; 95% CI = 1.28 - 4.74), compared with those watching TV less than 1.5 hr/day. The higher risk of obesity observed in high level of leisure time activity than in low one was considered due to that physical activity at work and leisure-time might counteract each other. Educational level and activity at work or leisure-time activity or TV watching were jointed and categorized, and then OR for obesity was estimated. The extent of obesity risk at a given level of each work activity or leisure-time activity or TV watching was different depending the educational level, which was significantly high when educational level was below middle school. Educational difference had no effect on activity level at work. However, higher educational attainment increased the leisure activity and reduced TV watching (p<0.05), indicating that low education tended to contribute to more sedentary life-style. The findings of this study is concluded that low education was related to obesity in adult males, and its relation can partly be explained through acquiring inactive life-style behaviors. Individuals with low education might be more susceptible to the risk factors of obesity.

  • When the head nurse who is pivotal in the nursing service administration of the hospital performs efficiently as a first-line manager, the effectiveness of the nursing unit, which includes the quality of nursing care, the jab satisfaction of staff members, and the cohesiveness of staff members is increased. With this point of view in mind, the researcher carried out a study to determine the actual work (the content of the work, the work process, the role of the head nurse, the activity media, and the purpose of the work) of the head nurse in a university hospital in Korea. In addition, this study was also carried out for the purpose of preparing an ideal model for the work of the head nurse. The research subjects were 39 head nurses. This included all the head nurses in two university hospitals except those who were working in outpatient care, operating rooms, central supply, nursing administration, in-service education and emergency care. Data were collected from September 24th to October 21th, 1987 and April 4th to 12th, 1988. A work activity record on which the head nurse recorded directly in a chronological narrative form, was used as the research instrument. The 234 work activity records, 39 head nurse's continuous recording over 6 days(from Monday to Saturday) were collected and analysed. The results were as follows ; 1. With regard to the work content for the total daily work of the head nurse, 45.2% of the activities were managerial activities but 58.1% of the head nurse' s time was spent in direct patient care. 2. With regard to the work process of the head nurse, specifically the location, the size and membership of groups contacted, the results were as follows : 1) Of the total daily work activities 92.4% were carried out in the nursing unit and this occupied 84.5% of total daily work time. Direct patient care was generally performed on the nursing unit and managerial work was performed in other areas. 2) Of the total daily work activities, 73% was with one or more persons and 51.2% of total daily work time was spent in groups. 3) A total of 51 persons, working in different capacities were contacted. These included 21 persons giving patient care, 19 persons working in nursing unit management, and 7 persons working in human resource management. 3. With regard to the head nurse's role in work activity, 53.3% of total daily work activities involved the informational role, 26.9%, the interpersonal role and 19.9%, the decisional role. With regard to time, 57.7% was spent in the informational role, 23.9%, in the interpersonal role and 18.3%, in the decisional role. When the head nurse performed managerial work, she gave nearly equal emphasis to all three roles when she gave direct patient care the informational role was increased. 4. With regard to the activity media, the number of unscheduled activities accounted for 27.1% of the activities, scheduled activities, 24.3%, desk work activity, 22.1%, rounds, 12.5% and telephone calls, made or received, 14.0%. In daily total work time managerial work related to desk work and scheduled activities were high, ranging from 29.8% to 29.9% but for direct patient care time, scheduled activities and unscheduled activities were high, ranging from 23.6% to 35.3%. 5. With regard to the purpose of the work performed, 54.4% of the total daily work was concerned with the team and 41.4% was concerned with the agency. The managerial work was concerned mainly with the team and the direct patient care was concerned mainly with the patient. When the frequency of an activity and time were compared no significant difference was found between the days for which the work was recorded for any of the variables : the work content, the work process, the work role, the activity media and purpose of the work. On the basis of this study the following are proposed as an ideal model for head nurse work in Korea : The managerial work should be increased to 70%. The decisional role activities should be increased to 40%. Twenty percent of the work activity should be allocated to agency, community and profession. It is believed that this model for the head nurse's work can contribute to guidelines for job description development. Finally, educational programs, organizational and structural devices, and administrative support are needed for the proper function of the head nurse in this proposed model.

  • Purpose: This study examined differences in nursing care activity, work performance outcomes, and job satisfaction associated with upgrading nurse staffing of a nurse-to-patients ratio. Methods: Descriptive design was used in this study. In total, 148 medical and surgical nurses were recruited from one university hospital. Three instruments were used for data collection: Scale of Nursing Care Activity, Nurses' Work Performance Outcome Measurement Scale and Nurses' Job Satisfaction Scale. Data were analyzed by using descriptive statistics, t-test, ANOVA, and paired t-test. Results: There were significant differences in nursing care activity (t=-5.06, p<.001), in work performance outcomes (t=-5.46, p<.001) and in job satisfaction (t=4.61, p<.001) when the grading for the nursing staff was changed from three to two indicating increasing number of nurses. Conclusion: The findings from this study showed that there were more nursing care activities, better work performance outcomes, and higher job satisfaction when numbers of nurses were increased. The changes in the scale to evaluate nursing staff influence nursing activities, work performance and job satisfaction.

  • The purpose of this study was to identify the relationship of nursing service satisfaction and nurse's nursing activity styles in a hospital settings. The subjects of this study were 150 admitted patients in a hospital. The data was collected with Nursing Service Satisfaction Scale developed by Tomas(1996) and modified Nurse's Nursing activity styles Scale developed by Coeling(1993). The results were as follows: 1. The mean score for the level of nursing service satisfaction was 65.00(SD=14.10). The mean score for subcategories of nurse's nursing activity styles were as follow; work difficulties management 9.47(SD=2.02), effective work attitude 23.53(SD=3.14), interpersonal relationship 48.82(SD=6.18), keep regulation 23.24(SD=3.62), professional values 48.28(SD=5.27), and professional development 24.41(SD=3.07). 2. The correlations of nursing service satisfaction and subcategories of nurse's nursing activity styles were revealed a positive significant correlation; work difficulties management(r=0.17, p=0.03), effective work attitude(r=0.44, p=0.00), interpersonal relationship(r=0.51, p=0.00), keep regulation(r=0.44, p=0.00), professional values(r=0.31, p=0.00), professional development(r=0.30, p=0.00). 3. Stepwise multiple regression analysis revealed that the most powerful predictor of nursing service satisfaction was effective interpersonal relationship. A combination of effective work attitude, work difficulties management account for 38% of the variance in nursing service satisfaction of the patient in a hospital. In conclusion, this study revealed that the effective work attitude, interpersonal relationship, and work difficulties management in nursing activity were important factors to improve the level of nursing service satisfaction.

  • Purpose: This study aimed to investigate the associations of sleep, dietary behaviors and physical activity with quality of life among shift-work nurses. Methods: For this cross-sectional descriptive study, data were collected from 191 shift-work nurses in a tertiary hospital. Multiple linear regression analysis was used to identify the relationships among variables. Results: The levels of sleep quality, dietary behaviors and physical activity were low. Factors associated with quality of life among shift-work nurses included sleep disturbance (B=-0.16, ${\beta}=-0.26$, p<.001), dietary behaviors (B=0.28, ${\beta}=0.24$, p<.001), and physical activity (B=0.05, ${\beta}=0.19$, p<.001). The strongest factor was sleep disturbance. Conclusion: In order to improve quality of life among shift-work nurses, it is significant to encourage and maintain health behaviors such as sleep, dietary behaviors and physical activity. Under the circumstances where shift-work cannot be avoided, personal efforts made by nurses to establish their own living standards for positive health behaviors will benefit their quality of life.

  • In this work we measured the total pressure of the aqueous solutions and the methanol-water solutions dissolved with inorganic salts, at $25^{\circ}C$. In organic electrolytes used in this work were $K_2SO_4$ and $(NH_4)_2SO_4$. Using the measured vapour pressures the activity coefficient of solvents and the mean ionic activity coefficient were obtained through thermodynamic relations. The activity coefficients of solvent and the mean ionic activity coefficirnt obtained in this work were fitted with Macedo's model and Acard's model. Both two models were good agreeable to the vapor pressure and the mean ionic activity coefficient for the electroyte aqueous solutions. For electrolyte /methanol/water solutions, Macedo's model had much deviation from experimental data, while Acard's model showed a good agreement with experimental data.

  • In order to investigate of the effects of rapid rotating shift work on physiological stress, the activities of urinary Na$^{+}$, $K^{+}$, Cl$^{[-10]}$ were measured in 14 rotational shift nurses, during day shifts(8AM-4PM, n=4), evening shifts(4PM-l2MN, n=5), and night shifts(12MN-8AM, n=5) in hospital twenty students attending nursing college a used as a control group. Urine specimens were collected in 30 minutes before and after work on the second day of shift work. In day shift nurses, Na$^{+}$ activity was 137mM at 8AM and increased to 206mM at 4PM, whereas $K^{+}$ activity was 42mM at 8AM and no significant change at 4PM. Cl$^{[-10]}$ activity was changed from 234mM to 344mM at 4PM at 8AM. In the evening shift, Na$^{+}$ activity was 117mM at 4PM and 140mM at 12MN, $K^{+}$ activity was 22mM and 32mM, respectively. Cl$^{[-10]}$ activity was 169mM and changed to 270mM. During the night shift, Na$^{+}$ activity was 128mM at 12MN and changed to 161mM at 8AM, $K^{+}$ activity was 42mM at 12MN and 8AM, and Cl$^{[-10]}$ activity was from 303mM and changed to 355mM. In general, the urinary ion activities seemed to increase after work, however there were no significant changes in ion activities except the Na$^{+}$ increase in day shift. The mean of the activities of $K^{+}$ and Cl$^{[-10]}$ before and after work during the day and night shift were significantly higher than those in control group (P<0.05). $K^{+}$ activities were also higher than that of evening shift(P<0.05). However, there was no difference in Na$^{+}$ activity among the control group and three shifts. There was a significant relationship among urinary Na$^{+}$, Cl$^{[-10]}$ and $K^{+}$ in the control group and rotating shift nurses except between Na$^{+}$ and $K^{+}$ in shift. The relationship between Na$^{+}$ and Cl$^{[-10]}$ was low in shift work and there was no significant relationship between Na$^{+}$ and $K^{+}$ in shift, suggesting that the active regulation $K^{+}$ and/or Na$^{+}$ in response to stress upon the shift work disruped the ratio of urinary Na$^{+}$ to $K^{+}$ and also lowered the relationship between $K^{+}$ and Cl$^{[-10]}$ . These results suggest that nurses working the day shift were overloaded and under stress, and the night shift interfered with the physiological rhythm of the nurses.red with the physiological rhythm of the nurses.
