This study was conducted to propose the model that is able to predict long-term settlement of sands containing carbonates. We can observe that in addition to the initial elastic compression, a considerable additional compression occurs with long-term period in some sands. The compressibility of sands is significantly dependent on particle characteristics. Some sands have many pores and particularly has an angular shape. To predict of long-term settlement of these sands which contain carbonates, first of all a variety of tests which are to assess chemical, physical and compression characteristics of these sands were conducted. Second, in order to know settlement with time, the time parameter was determined by analyzing the measured data obtained from $\bigcirc\bigcirc$ area. The measured settlement of this area shows that in addition to the initial elastic compression, a considerable additional compression occurring with time. It was caused by the crushing, shattering, and rearrangement of particles, which were real phenomena in sandy soils under loading condition. Based on this case study, we proposed that a simple method is able to predict settlement with time of sandy soil containing carbonates.

Purpose: The purpose of this study was to identify the influencing factors on turnover intention of nurses in long-term care hospitals. Methods: Data were collected from 210 nurses in 11 long-term care hospitals in B city. Data were analyzed using descriptive statistics, t-test, ANOVA, Pearson's correlation coefficient, and Stepwise multiple regression. Results: Turnover intention was significantly correlated with emotional labor(r=.35, p<.001) and job involvement (r=-.38, p<.001). In a multiple regression, emotional labor (${\beta}=.31$, p<.001), age (${\beta}=-.27$, p<.001), job satisfaction (${\beta}=.24$, p<.001), job involvement (${\beta}=-.23$, p<.001), and number of patients assigned(${\beta}=.14$, p=.009) were associated with turnover intention. These factors attributed to 41.2% of the total variance in turnover intention. Conclusion: Considering the results of this study, proactive educational and/or human resource management interventions need to be developed especially for those younger nurses in order to reduce emotional labor as well as to promote job satisfaction and job involvement of nurses in long-term care hospitals.

WO$_3$/SnO$_2$ceramics has been suggested as an effective sensing material for monitoring offensive odor or pollutant gases. This work was focussed on improving long-term stability, which has been a principal problem generally taking place in SnO$_2$semiconductor gas sensor. Miniaturized thick film gas sensors were fabricated by screen printing technique. Two types of sensor materials, W doped SnO$_2$and WO$_3$mixed SnO$_2$, were comparatively investigated on those long-term stability and sensitivites to several gases. Small amount of W doping(0.1 mol%) into SnO$_2$largely improved the long-term stability. The W(0.1 mol%) doped SnO$_2$gas sensor had higher sensitivities to both acetone and alcohol compared with WO$_3$(5 wt%) mixed SnO$_2$gas sensor. On the contrary, WO$_3$(5 wt%) mixed SnO$_2$gas sensor showed more superior sensitivity to cigarette smoke due to larger W content.

Mountainous areas cover more than 70% of Korea. With the rapid increase in tunnel construction, tunnel-collapse incidents and excessive deformation are occurring more frequently. In addition, longer tunnel structures are being constructed, and geologically weaker ground conditions are increasingly being encountered during the construction process. Tunnels constructed under weak ground conditions exhibit long-term deformation behavior that leads to tunnel instability. This study analyzes the behavior of the bottom region of tunnels under geological conditions of long-term deformation. Long-term deformation causes various types of damage, such as cracks and ridges in the packing part of tunnels, as well as cracks and upheavals in the pavement of tunnels. We observed rapid tunnel over-displacement due to the squeezing of a fault rupture zone after the inflow of a large amount of groundwater. Excessive increments in the support member strength resulted in damage to the support and tunnel bottom. In addition, upward infiltration pressure on the tunnel road was found to cause severe pavement damage. Furthermore, smectite (a highly expandable mineral), chlorite, illite, and hematite, were also observed. Soil samples and rock samples containing clay minerals were found to have greater expansibility than general soil samples. Considering these findings, countermeasures against the deformation of tunnel bottoms are required.

The application of the high-performance insulation materials for buildings seems to be an essential measure for reducing energy use in buildings. Phenolic foam is a readily available insulation material with thermal conductivity of about 0.018 to 0.020 W/(mK). It has the advantage of higher thermal resistance and better fire resistance compared to other conventional building insulation materials. Insulation material used for building envelope is regarded as one of the decisive factors for building's energy load. Furthermore, the degradation of its thermal performance over time increasingly affects the building's energy use demand. Generally, the life span of conventionally built buildings is expected to be more than 50 years, so the long-term performance of insulation materials is critical. This paper aims to evaluate the long-term performance of phenolic form boards through an accelerated aging test. The tests were conducted according to BS EN 13166 and KS M ISO 11561. Based on the results of the accelerated aging test, the thermal performance variation of the material was analyzed, and then its aged value after 25 years was computed. Also, the characteristics of the phenolic foam board's long-term performance were also examined based on the standard testing methods adopted.

Purpose: This study aimed to evaluate economic viability of public health center visiting nurse services for the low-income elderly with long-term care needs. Method: The sample consisted of 252 community dwelling elderly who enrolled in public health center visiting nurse services for three months or more. Data was collected on physical (ADL and IADL) and cognitive impairments of the elderly, contents and frequency of visiting nurse services, cost per visit, and costs of alternative services for long-term care. Result: The mean score of ADL and IADL levels of the elderly was 2.80.4904, which indicated these patients were mostly independent. Eighty four percent of the elderly subjects were cognitively intact. Among visiting nurse services supplied, providing assessment was 34%, followed by education and counseling 26%, medication 22%, and referral. The mean cost per visit was 17,824.1 won, which transformed into a total cost per person per year of 161,130.2 won. Comparing the cost of a visiting nurse service with those of other long-term care alternatives, the visiting nurse service was the least costly alternative, followed by an outpatient clinic, hospital based home care, and nursing home. Conclusion: Overall, the results of the study provide evidence of the economic viability of visiting nurse services for the low-income elderly among long-term care alternatives.

Purpose: Ageing in place may improve the quality of life of frail elderly and decrease their costs of services. The purpose of this study was to examine the factors that influence the institutionalization of elderly using home care services in a Korean long-term care insurance system. Methods: This study used the data of '2009 Satisfaction survey of Korean long-term care system'. The survey proceeded to use a sampling data based on region, level of long-term care need, and insurance type among the beneficiaries between August and September 2009. The onset dates of institutionalization of 1,095 participants were ascertained from long-term care insurance claim data. This study calculated the hazard ratio through the Cox Proportional Hazard Model. Results: A total of 176 subjects who were institutionalized in nursing homes were included. There were higher risks in the group that included those who were 85 years and over, had dementia or fracture, used home-visit nursing service, and were not supported by direct family. Conclusion: The results of this study have policy implications to supplement the home care service system and postpone nursing home institutionalization of elderly.
