We consider the online scheduling problems of three and four machines under eligibility constraint. Respectively for the cases of three and four machines, we prove that AW algorithm has competitive ratios of $\frac{5}{2}$ and 3 which are shown to be optimal. Also, we show that the same results hold for the semi-online cases with prior knowledge of the total and the largest processing time.

Purpose: This study is for the facility eligibility and improvement evaluation analysis for the patient care environment of 7 facilities which has national inpatient isolation units. Methods: For the evaluation, first of all, the patient care environment of national inpatient isolation units are scrutinized by the checklist which is used on from 2014 with the 4 fields of criteria : architectural planning and layout, general requirement and condition for operating the negative pressured isolated patient room, HVAC system, and waste water discharging system. Finally, the evaluation results are compared with that of 2014. Results: The result shows that the average value of facility eligibility is 89.3 percent and which is 8.9 percent higher than the value before the MERS occurred. Implications: It is clear that facility remodeling of 7 institutions is being performed continuously, and the result of facility eligibility evaluation is reflected on design of a new 21 national inpatient isolation units those are going to be constructed from 2016. Therefore, it is expected that this study is used as a practical reference to establish the criteria of patient care environment management and safety management for both infectious disease outbreak and general service condition.

Online parallel machine scheduling problems have been studied by many researchers and enormous results are appeared in the last 40 years. With the development of scheduling theory and application, new online scheduling problems where the partial information is known in advance, that is, semi-online, gained much interest due to their increased application in practice. So we consider the online scheduling of three machines with general eligibility and its semi-online variant where the total processing time is known in advance. For the online and semi-online problems, we develop algorithms with competitive ratio of 5/2 which are shown to be optimal.

We consider scheduling jobs on multipurpose machines where jobs can be processed by a subset of the machines operated in parallel with the objective of minimizing makespan. We apply LPT(Longest Processing Time first) algorithm and prove that its posterior worst-case performance ratio is at most $log_24m/(1+{\lambda})$, where \lambda is the number of machines eligible for processing the job with the latest completion time. In general, LPT is shown to always find a schedule with makespan at most $log_24m/3$ times optimum.

The purpose of this study is to predict the roles of public social workers and clarify their job. There were a few studies concerning them, and they suggested that it was needed to reform the delivery system or to supplement personnel. But they were almost normative. This study, based on the literature, analyzed public social workers' daily works to suggest their desirable roles. Generally the job of public social workers consists of two functions. One is income maintenance function, the other is social services function concerned with economically disadvantaged. The result showed that these functions were meshed up to now. Especially, It also showed that although they performed mostly eligibility work related public assistance and general practices, they wanted to perform professional practices. Took into account their working conditions, it seemed to be desirable to clarify their job. Thus, several suggestions based on these results are as follows: First, while eligibility functions are the central aspects of the public social worker's roles, it is needed for them to provide selected access services. Second, if they wanted to perform social services, it would be needed to restrict their roles for case manager and broker.

Purpose: The purpose of this study was to address the difference menopausal symptoms according to sasang constitution and menopausal status among perimenopausal women. Methods: Data for this cross-sectional study was collected by administering questionnaires that elicited general information. The menopause rating scale (MRS) and Questionnaire for the Sasang Constitution Classification II (QSCC II) was given to 284 perimenopausal women who met the eligibility criteria and agreed to participate in the study. Results: The study subjects were composed of 27.5% so-yangin, 24.6% so-eumin, 18.7% tae-eumin, and 29.6% undefined category. The total MRS and all subscales were significantly higher for postmenopausal women in comparison to premenopausal women. Especially, so-eumin and tae-eumin displayed significantly higher scores in urogenital symptoms. The MRS score in postmenopausal women who belonged to the group of tae-eumin and so-eumin was significantly higher than those for premenopausal women. However, so-yangin displayed higher scores in psychological and urogenital symptoms than tae-eumin for premenopausal women. So-eumin presented significantly higher scores in urogenital symptoms in comparison to the undefined category for postmenopausal women. Conclusion: These findings suggest that sasang constitution could be an important factor in understanding the woman's menopausal symptoms and identify the best treatment.

This study has been performed to analyze association between general housing status and demographic characteristics such as family extension period, total fertility within a family, male birth rates, and birth order among the elderly in Korea. In this study, 183 subjects aged late 60s to 70s were interviewed for their childbearing history under legal marriage and current housing status such as tenure, residence(urban vs rural), and household composition. In this study , average term from the first to the last birth is 11.88 years, and total number of live births is 4.51. The average rate of male firths among live births within a family is 0.532, which is close to data of Korean statistical office in 1995. There were some association of housing status and the fertility; those living in rented units have longer family extension period and rural elderly have higher rate of male children. in addition, there is a significant impact of birth order on tenure. Majority of the first-born subjects were home owners by virtue of bequeath eligibility, and the rate of home owners was 50% higher than the second-born group. Overall in this study, it is recommended that when planning elderly living facilities, service policies be differentiated by both housing & fertility characteristics.

Purpose: The purpose of this study was to identify the factors influencing dementia preventive behavior intention of the elderly people based on the Health Belief Model. Methods: The participants included 113 elderly people who met the eligibility criteria. Demographic variables, variables of the Health Belief Model (perceived susceptibility, perceived severity, perceived benefit, perceived barrier, cues to action, general health motivation, and self efficacy), dementia fear and behavioral intention of dementia prevention were examined using structured self-report questionnaires. Statistical analysis was performed by stepwise multiple regression using SPSS for Windows version 21. Results: Self efficacy, alcohol drinking, perceived barrier and education level were significant factors, which explained 32% of the variance in dementia preventive behavior intention. Multiple regression analysis demonstrated that a powerful predictor of dementia preventive behavior intention of the elderly was self efficacy. Conclusion: Developing nursing intervention to enhance self efficacy toward improvement of dementia preventive behavior among elderly people would be recommended.
