Purpose: The purpose of this study was to compare reported physical symptoms, hope and family support of cancer patients between general hospitals and long-term care hospitals. Methods: Subjects were 175 patients diagnosed with cancers from two general hospitals and six long-term care hospitals located in G city. Subjects completed a questionnaire with questions about general characteristics and questions about the disease, physical symptoms, hope and family support. Data was collected from February to April and the data were analyzed using an independent t-test and one-way ANOVA. Results: The subjects in long-term care hospitals showed higher percentage in pain, nausea, fatigue, sleep disorder, and change in appearance. There was a significant difference in family support between two groups. A significant positive correlation was found between hope and family support in subjects in general and long-term care hospitals. Conclusion: Significant differences were found in some physical symptoms and family support between cancer patients in general hospitals and long-term care hospitals. Thus, nurses in long-term care hospitals need provide care suitable for the characteristics of cancer patients in long-term care hospitals.

Serviceability of reinforced concrete building is affected dominantly by long term deflection of slab. And in case of reinforced concrete building with flat plate slab, severe long term deflection was expected because it has no beams which have large flexural stiffness. Therefore it is important to calculate exactly long term deflection of RC flat plate structure to assure its serviceability. However, current codes couldn't calculate exactly long term deflection of RC flat plate structure because they don't consider effects of boundary condition and construction load. By the way, recently the method to calculate long term deflection of RC flat plate structure was proposed by considering these effects. In the present study, long term deflection of RC flat plate structure was analyzed by comparing this method with recent experimental results. In conclusion, long term deflection of RC flat plate structure was affected considerably by effects of boundary condition, construction load and tensile strength of concrete. And recently proposed method considers these effects reasonably but it should be modified to reflect creep effect of RC flat plate slab reasonably.

Purpose - This study aims to examine whether family firm governance is related to long-term corporate survival. To find out whether and why family firms have higher chances of long-term survival compared to non family firms, this study analyzes the relationship between some governance characteristics that are prevalent in family firms and corporate long-term viability. Design/methodology/approach - This study utilizes a sample of 285 family firms listed on the Korea Stock Exchange (KSE) to probe the influence of governance characteristics on corporate survival. This study conducts Cox proportional hazard regression analysis to estimate the influences on the survival duration. Findings - The results indicate that firms with particular governance characteristics show higher long-term survivability. Specifically, the probability of firm's long-term survival is increased when the CEO is the largest shareholder, which may be related to CEO's stewardship attitudes. Research implications or Originality - This study has significance in that it examines the direct causal variables that enhance long-term corporate viability through a large scale empirical examination. Also, the study findings provide some clues as to why certain family firms outlive non-family firms.

Improving long-term performance in highway projects is an imperative goal for public administrations. Project delivery and procurement methods might provide an opportunity to align design and construction processes with this goal. Previous studies have explored whether project delivery methods impact the long-term performance of highway projects. However, these studies did not focus specifically on how core elements within the procurement might relate to long-term performance. Thus, this research aims to fill this gap by exploring to what extent and how long-term evaluation criteria are considered in design-build best-value procurement of highway projects. To this end, content analysis was conducted on 100 projects procured between 2009 and 2019 by 19 DOTs across the U.S. The analysis of 365 evaluation criteria found that (1) roughly 11% of them related to long-term performance. (2) The weight given to these criteria in the overall technical proposal was lower than 30%. (3) Sixty-five percent (65%) of long-term evaluation criteria focused on design while 15% related to materials and technology, respectively. The results of this study are a first steppingstone to initiate a deep exploration of the relationship between procurement practices and actual project performance. Currently, with sustainability and life cycle assessments being top concerns in infrastructure projects, this line of research might be of particular interest to DOTs and highway agencies across the U.S. and worldwide.

Purpose: The purpose of this study was to explore the subjective experience of moral distress among nurses working in long-term care hospitals. Methods: A phenomenological approach was used for the study. Data were collected from May to July, 2019 using open-ended questions during in-depth interviews. Participants were nurses working in long-term care hospitals and had reported experiences of moral distress. Nine nurses participated in this study. Results: Three themes emerged from the analysis using Colaizzi's method: (1) confusion and distress about the meaning of care, (2) a feeling of helplessness caused by connivance, (3) enduring in the organization. Conclusion: Sufficient labor supply, environmental improvements, programs for improving interpersonal skills, education and counseling on end-of-life care, and recognition improvement about long-term care hospitals are suggested to reduce the moral distress of long-term care hospital nurses.

Purpose - This paper investigates the long term impact of RFID investment on firm value in Korea. We wand to find out why the long term performance of some firm's RFID investment is better than others. To understand the dynamics of the long term returns from RFID investment announcements, we divide our events into groups for each of the independent firm characteristic variable such as investment time period, kind of markets, industries, solvency and growth potential. We composed portfolios based on the RFID investment announcement date for each group and evaluate the monthly abnormal excess returns. Research design, data, and methodology - Based on these calendar-time portfolios, we measure the long term returns from 86 RFID investment announcements of 46 firms from 2003 to 2017. We construct the calendar-time portfolio for 3, 6, 9, 12 months of holding periods. Using the weighted least squares method, we regress the raw monthly returns of the portfolios on the Fama-French model and Carhart(1997) model. As a result, we can get the estimated risk adjusted mean monthly abnormal excess return α_P for each of the calendar-time portfolio. Results - We found that early adopters, large firms, non-manufacturing firms have very significant excess returns. We also found modestly significant excess returns for financially stable firms and slow growing firms. Put together, top managers of the firms which plan to invest RFID should understand the strategic role of RFID adoption and the generalized business process of distribution information technology investment in Korea. Moreover, the findings of this paper provide useful trading strategies to the managers of large funds who are considering on investing in RFID adopting firms. Conclusions - Put together, the results of this paper give us a new insight into how the RFID and IT technology in general and other characteristic factors' interactions affect the long term performance of firms. Using the unbiased estimates of long term returns of the calendar-time portfolios, this paper extends the understandings on short term impact of RFID adoption of existing studies. This paper also extends the current understandings of firm characteristics that affect the long term performance of RFID adopting firms.

Purpose - This study focuses on long-term orientation that can lead long-term partnership. A long-term orientation needs a trust and relation commitment between company. So in this study, the researcher conducts a dependent variable as a justice recognition and brand asset value to research model to find out casual relationship among quoted factors. Research design, data, and methodology - The focus of this study was employees who work in a liquor distribution company to figure out factors that effect on long-term relationship in b2b transaction. The development of the research model is based on the literature of the preceding research analysis of justice recognition, brand asset value, trust, relation commitment and long-term orientation. This study have constructs that defined operationally by previous studies, research model design that to figuring casual relationships among the quoted factors. From 2016 Sep. 1st to Oct. 30th, a questionnaire survey was conducted targeting employees who work in liquor distribution company. 176 survey data were used for empirical analysis to prove the research hypotheses. Results - The main results of this study's empirical methodology were as follows. First, procedural justice and interactive justice has a positive significant effect on trust and relation commitment. Also brand image, brand awareness and perceived quality has a positive significant effect on trust and relation commitment. Second, trust and relation commitment has a positive significant effect on long-term orientation. Every hypothesis adopted as the researcher designed for empirical study. Conclusions - Based on empirical results, this study confirmed that trust and relation commitment has empirical relationship with long-term orientation. Based on the analysis, the researcher provided managerial implication by setting 2 way path for making long-term orientation with business company. First path is procedural justice to relation commitment. It contains that procedural justice recognised while business transaction execution, consideration intension and relation development will happen in b2b. Second path is perceived quality to trust. It contains that the perceived quality recognised while business transaction execution, trust will increase rapidly. So when a business company wants to make a partnership, they have to consider procedural justice and perceived quality to make a long-term relationship.

Objectives : This study was performed to investigate the characteristics and ADL(Activities of Daily Living) associated factors of elderly inpatients in long-term care hospitals. Methods : Data were collected from the nationwide data of 'Survey of Patients (2013-2014)' administerd by the Ministry of Health & Welfare. The data included in this study consisted of 27,606 cases of elderly inpatients in long-term care hospitals. Results : The survey scores for the elderly inpatients were as follows: 57.6% 'Needed much and total help' with ADL, followed by 26.6% who 'Needed much help', and 15.8% who 'needed minimal supervision' in long-term care hospitals. The ADL score was high in the following categories: women, old age, referred visit, health insurance type, not-recovered & death, transferred, corporate hospitals, small hospital size, low number of physicians per 100 beds, and high number of nursing staff per 100 beds. The inpatients with 'diseases of the nervous system', 'diseases of the circulatory system' and 'diseases of the genitourinary system' were more likely to have high ADL scores. Conclusions : The results of this study suggest that long-term care hospitals should provide active and proper care for patients with high ADL scores and improve medical personnel training as well provide more medical care.
