Purpose: The aim of this study was to explore the elderly women patients' experience of treatment for total knee replacement. Methods: The participants in this study are 10 elderly women age 65 and over who were discharged after total knee replacement. The data were collected from August 5, to September 20, 2012, and it has been done by in-depth interview. Data were analyzed the phenomenological method of Colaizzi. Results: In this study, four categories were extracted: 'Suffering due to intolerable pain', 'A stable mind and body', 'Retrospection about old wounds', 'A desire for a new life'. Conclusion: This study provides the useful basic data to understand the elderly women patients who have experienced total knee replacement. Nursing intervention is required for pain control after surgery in order to improve the quality of life. In addition, nursing care through individual counseling and emotional support during the recovery period is very important. Therefore, various programs should be developed for elderly women patients to help their body recovery as well as psychological support after total knee replacement surgery.

Under the situation which customer orders are cancelled unless all products in the order are delivered all at once, this paper concentrates on the purchase dependent demands and explores the systematic approach to implant the purchase dependence into the multi-product inventory model. First, by acknowledging that it is a challenging task to formulate a suitable inventory model for the purchase dependence, we derive the optimal solution condition using an EOQ model and extend the optimal solution condition to periodic review models. Then, through the comparison simulation of four inventory policies regarding several degrees of purchase dependence, we demonstrate that the inventory models which consider the purchase dependence generate less total cost than the inventory models which ignore the purchase dependence. In general, the inventory models which consider the purchase dependence reduce the loss of sales by maintaining more inventories, which results in reducing the total cost. Consequently, the simulation result supports the effectiveness of this paper's approach. In addition, this paper uses the individual order period and joint order period obtained from the EOQ model for the multi-product inventory model. Through the in-depth analysis of comparing the two models, we observe that the model of using the joint order period produces less total cost when the degree of purchase dependence is high, but the model of using the individual order period produces less total cost when the degree of purchase dependence is low.

High-stress and complex geological conditions impose great challenges to maintain excavation stability during deep underground mining. In this research, large anisotropic deformation and its management by support system at a deep underground mine in Western Australia were simulated through three-dimensional finite-difference model. The ubiquitous-joint model was used and calibrated in FLAC3D to reproduce the deformation and failure characteristics of the excavation based on the field monitoring results. After modeling verification, the roles of mining depth also the intercept angle between excavation axis and foliation orientation on the deformation and damage were studied. Based on the results, quantitative relationships between key factors and damage classifications were presented, which can be used as an engineering tool. Subsequently, the performance of support system installation sequences was simulated and compared at four different scenarios. The results show that, first surface support and then reinforcement installation can obtain a better controlling effect. Finally, the influence of bolt spacing and ring spacing were also discussed. The outcomes obtained in this research may play a meaningful reference for facing the challenges in thin-bedded or foliated ground conditions.

The behaviour of reinforced concrete moment resisting frame structures in recent earthquakes all over the world has highlighted the consequences of poor performance of beam column joints. Large amount of research carried out to understand the complex mechanisms and safe behaviour of beam column joints has gone into code recommendations. This paper presents critical review of recommendations of well established codes regarding design and detailing aspects of beam column joints. The codes of practice considered are ACI 318M-02, NZS 3101: Part 1:1995 and the Eurocode 8 of EN 1998-1:2003. All three codes aim to satisfy the bond and shear requirements within the joint. It is observed that ACI 318M-02 requires smaller column depth as compared to the other two codes based on the anchorage conditions. NZS 3101:1995 and EN 1998-1:2003 consider the shear stress level to obtain the required stirrup reinforcement whereas ACI 318M-02 provides stirrup reinforcement to retain the axial load capacity of column by confinement. Significant factors influencing the design of beam-column joints are identified and the effect of their variations on design parameters is compared. The variation in the requirements of shear reinforcement is substantial among the three codes.

Purpose: This study was aimed to describe older adults' experiences of living with urinary incontinence and using diapers for its management in long-term care facilities. Methods: Qualitative data were collected through in-depth interviews with 22 participants in long-term care facilities. Content analysis was used to analyze the data. Results: Three themes and six categories were emerged. Participants navigated through those three categories as stages, including the initial stage of confronting the unacceptable reality, transitional stage of physical and emotional suffering, and adaptive stage of accepting the diaper usage as a part of life and hoping improvement. Six categories were feeling terrible with unavoidable use of diapers, being frustrated by nursing staff shortage and unsatisfactory care for urinary incontinence, physical discomfort from of wearing diapers and remaining unchanged, emotional difficulties due to using diapers, accepting and adapting to diaper usage as a part of life, hope for gender-specific quality care for urinary incontinence. Conclusion: The findings suggest that using diapers should not be mandatory to manage older adults' urinary incontinence in long-term care facilities. It is also critical to establish policies to address issues of nursing shortage and financial support for qualitative care to manage urinary incontinence in long-term care settings.

Purpose: This study examined: 1) what it meant for patients to have multimorbidity 2) how they manage their illness using health care facilities, and 3) what contextual backgrounds exist regarding the health care system. Methods: This qualitative research obtained individual in-depth interviews from 22 patients. Participants were selected by purposive sampling among those who saw physicians more often than the national average from the 2013 medical-claim data. The transcribed data were analyzed using Ground theory. Results: Multimorbidity patients suffered from "chain-like serial symptoms" and "pain without a breakthrough". They expressed themselves as "indeed patients among patients", "my body is a general hospital", and "an incompletely normal person". There was a demand to resolve the anxiety arising from the situation in which the body keeps getting sicker without showing any signs of recovery. In a state of reduced social support and a lack of trust in the doctor, their desire to be healed led them to receive a temporary relief through dependence on medical institutions. Conclusion: This research recognized the desire of multimorbidity patients to seek temporary relief through dependence on medical institutions. A more patient-centered directed care plan, specific to the needs of the patients with multimorbidity is required.

Purpose: This qualitative study aimed to explore the experiences of patients with diabetes provided with medication monitoring using an artificial intelligence-based smartwatch. Methods: Giorgi's descriptive phenomenological methodology was applied to collect and analyze data from November 9 to December 23, 2021. The study samples were recruited by convenience sampling, and even patients with diabetes participated in in-depth interviews via video conference and telephone calls or face-to-face visits. Results: Ten sub-themes and four themes were finally revealed. The four themes were as follows: journey with unfamiliar devices, a less-than-acceptable smartwatch, insufficient functions and content for patients with diabetes to use, and efforts for regular medication behaviors and daily monitoring of patient's health conditions. Conclusion: To effectively manage diabetic conditions using digital healthcare technologies, nursing interventions were needed to identify personal needs and consider technological, psychological, aesthetic, and socioeconomic aspects of wearable devices.

Purpose: This study was a descriptive research to identify the relationships among burden from behavioral psychological symptoms of dementia, dementia attitude, emotional labor and nurse's caring behavior as well as to clarify factors that affect caring behavior of nurses in long-term care hospital. Methods: For the research, this study collected data from July 8 to July 20, in 2019 with 214 nurses who worked at 10 long-term care hospitals in Chungbuk. The data were analyzed using descriptive statistics, t-tests, Mann-Whitney U test, ANOVA, Pearson's correlation coefficient, stepwise multiple regression with the SPSS 23.0 program. Results: Factors influencing caring behavior of nurses in long-term care hospital were dementia attitudes (β=.549, p<.001), burden from behavioral psychological symptoms of dementia (β=.242, p<.001) and marital status (β=.134, p=.017). These factors explained 33.9% of caring behavior (F=37.35, p<.001). Conclusion: Dementia attitudes were confirmed to be the main variable influencing nurse's caring behavior. Therefore, to improve the caring behavior of dementia patient, it is considered that the development of programs to improve dementia attitudes and in-depth understanding regarding the behavioral and psychological symptoms of dementia is necessary.

A popular alternative to extend the life of aged pavement is asphalt overlay. However, it has a very serious and inherent shortcoming in deterring a reflection crack. Although joint-rehabilitation and stress-relief techniques have been applied to deter such reflection cracks in aged pavement, the techniques had a limited success only in slowing down the progress of a reflection crack. Rubblization technique rubblizes the concrete pavement slab in situ and uses the rubblized slab as the base material. Then, pavement overlay is applied to finish off the rehabilitation of aged pavement. This rubblization technique has the advantage of solving the problem of reflection cracking completely. When rubblization technique is applied, the upper layer of aged concrete pavement is rubblized between 40mm-70mm in depth. However, the lower layer is typically rubblized more than 100mm in depth. Nevertheless, it is difficult to turn the entire concrete pavement of more than 30cm in depth into rubblized aggregate of appropriate size. Thus, a simulation experiment was carried out to find the appropriate rubblized depth, which avoids the reflection cracking and still maintains the function of subbase, by varying the depth of rubblized depth in loom increments of 0cm, 10cm, and 20cm. The result indicated the optimum rubblized depth was 10cm (Lee, 2006). Additionally, a small rubblizinge equipment was developed in order to derive the rubblization technique appropriate for thick concrete pavement. This equipment was tested out on an experimental pavement, which was constructed with the same standard and specification for the road in actual use, by varying its rubblizing head shape and energy as well as the effective area of rubblization. This experiment led to a prototype equipment for rubblization of thick concrete pavement. The prototype was put into use on a highway, undergoing a test construction and monitoring afterwards. This entire process was necessary for the validation of the proposed rubblization technique.
