As the scarcity of natural resources has become apparent, the recycling industry has emerged as a promising one for its growth potential. Yet, the recycling industry still remains undeveloped and inefficient for various reasons. In this study, we focus on firms' recycling processes to understand the current status of recycling firms' value creation activities. With respect to the adopted recycling processes, we empirically investigate the differences in firm characteristics and firm performance. We use the data from Keco (Korea Environment Cooperation) which annually conducts a survey of recycling firms in Korea. We exclusively consider the whole group of plastic recycling industry in order to control for a possible bias in firm performance, stemming from the heterogeneity in processing and recycling of materials other than plastics. We review the descriptive statistics from the sample firms and conduct a series of hierarchical regression analyses. The results show that most of the firms in this industry adopt physical transformation processes with a low-level technology. These firms with physical transformation processes are smaller in size and produce entry level items which do not secure higher margins. The results indicate that the recycling industry largely comprises low value added firms which lack economies of scale and resources for R&D. For the stable growth of the industry, recycling firms must create sustainable values through implementation of technology-driven processes and improvement in product quality. In addition, the government should help build a reliable reverse logistic network, lower the entry barriers, and provide necessary funding for the SMEs in the recycling industry.

Purposes: The purpose of this study was to identify the factors related to the long-stay hospitalization of dementia patients aged 65 years or older who had received inpatient care at geriatric hospitals according to the minute facility characteristics and patient features. Methodology: This study was conducted on 317,353 cases of 1,512 geriatric hospitals using the Health Insurance Review and Assessment Service dataset. The data collected were processed using the SAS Enterprise Guide 4.3 for descriptive statistics, the chi-square test, and the binary logistic regression analysis. Findings: As a result of the study, in the facility characteristics of geriatric hospitals, the long-stay hospitalization of the aged with dementia were found to be related to the type of facility establishment, the number of hospital beds, the number of medical specialists, the number of nursing personnel, and the number of geriatric hospitals by region and province. In the personal features of patients, the long-stay hospitalization was found to be associated with the gender, age, insurance, and the patient classification groups. Practical Implication: Considering the results of this study, it seems that securing the sufficient medical personnel in a geriatric facility, providing the good quality medical services, and preparing the appropriate discharge plan can reduce the unnecessary long-stay hospitalization and spend the medical expenses for the older patients.

This study is to design an effective fall-prevention nursing program. Researchers investigated the current condition and risk factors for falls in the small-medium sized rehabilitation hospital with descriptive research. We conducted integrative literature review to reflect the current approach of fall-prevention nursing program. We found that the risk factors for falls are related to the characteristics of clinical setting of the hospital. We suggested the nursing intervention with applying fall risk assessment scale that is sensitive to the elderly population and the intervention that shows maximum effect. In conclusion, this study proposed the way of selecting an effective fall-prevention nursing program based on a clinical setting and prospective of its application. This will contribute to the improvement in nursing practice with the critical view in hospital fall.

Purpose: The purpose of this study is to assess the status of the Human research Protection Program (HRPP) within a hospital or a research institute in Korea. Methods: Survey was conducted during June 12th-21th 2019. Survey was distributed to the members of Korean Association of IRB (KAIRB) through each IRB office. Descriptive statistics were performed using SPSS ver. 26. Results: A total of 86 people responded, and 75 (87.0%) answered that they have perceived the HRPP. Seventy out of 86 respondents (81.4%) were conducting internal audit, several institutions were operated simultaneously the other form of audits such as IRB audit, system audit. Regarding the management of Suspected Unexpected Serious Adverse Reaction (SUSAR), 62.8% answered that they have regulation that can decide to suspend the study when there is a risk to subject safety. Among the respondents, 66.3% performed 'Help desk.' Conclusion: In this study, we assessed the current status of HRPP operation at each research institution based on Ministry of Food and Drug Safety (MFDS) HRPP guidelines. The HRPP accredited institution operated the subject protection activities according to this program, and even if the HRPP was not officially operated, the related activities were conducted focusing on the cases that could have a significant impact on the safety of research subjects. In order to ensure the quality of domestic clinical trials and to stably establish the HRPP, efforts at the individual institution level will be required.

The purpose of this study was to explore the various data and methods employed by HR analytics studies. The researchers selected 78 KCI-indexed empirical articles on HR analytics and categorized them using the Employee Life Cycle framework. This yielded several important findings. First, employee retention has been the most common subject of extant studies, followed by performance management. Second, HR analytics studies have used a variety of data (structured and unstructured) according to their research questions, and the data sources have ranged from organizations' internal systems to national databases. Third, most domestic HR analytics studies have been descriptive and diagnostic, whereas predictive and prescriptive studies have been rare. These results have important theoretical and practical implications for future HR analytics research.

Objectives This study aimed to analyze the medical utilization of low back pain (LBP) patients after back surgery and estimate the medical costs of Korean and Western medicine collaborative treatment, odds ratio, and hazard ratio between the two groups using the 2019 Health Insurance Review and Assessment Service-National Patient Sample (HIRA-NPS-2019). Methods Data management and descriptive analysis, logistic regression, and survival analysis were conducted for defining and estimating the LBP patients after back surgery in the NPS 2019 dataset. Results A total of 216,424 patients out of 991,189 were identified as having LBP. Among the patients with LBP, 1,734 were treated with surgery while 214,690 were not. Among those who had surgery, 937 were treated with conventional treatments only and 797 underwent Korean medicine treatments. The odds ratio of the logistic regression analysis was 0.7129, suggesting that Korean medical treatment experience group had a 28.7% lower risk of reoperation than the Western medical treatments only group. The hazard ratio of the survival analysis was 0.9145; thus, the risk probability of reoperation was estimated to be approximately 8.55% lower. The 50% risk of reoperation was 69 days (0.5044) for the conventional group, and 97 days (0.5008) for the Korean medical group in the survival analysis using the Kaplan-Meier graph. Conclusions These results could be utilized in future studies in conducting economic evaluation for estimating cost-effectiveness of Western medicine and Korean medicine treatment compared to Western medicine alone in LBP patients after back surgery in a South Korean perspective. mended and should be applied while taking the necessary precautions.

Purpose: The purpose of this study was to analyze the factors associated with long-term hospitalized patients in long-term care hospitals using the quality assessment data for long-term care hospitals by the Health Insurance Review. Methods: Among 1,376 long-term care hospitals, frequency analysis and descriptive statistics were used to analyze the characteristics of these hospitals. Multiple linear regression was conducted to examine the associations between infrastructure characteristics, medical personnel characteristics, health outcomes and the proportion of long-term hospitalized patients. Results: The research findings indicate that the number of patients per doctor, the number of patients per nurse, and the number of patients per nursing staff were positively associated with the proportion of long-term hospitalized patients. Among health outcomes, a higher proportion of patients with more than a 5% weight loss compared to the previous month and the proportion of patients showing improvement in ADL, were more likely to have a lower proportion of long-term hospitalized patients. However the proportion of diabetic patients with HbA1c test results within the appropriate range was positively associated with the proportion of long-term hospitalized patients. Conclusion: The present study results provide fundamental data for the establishment of policies for long-term care hospitals. Based on this study, it is important to suggest screening methods for unnecessary long-term hospitalizations, such as sufficient medical personnel to improve the quality of care in long-term care hospitals. It is also necessary to clearly separate the roles of medical institutions and long-term care facilities and implement policies to support patients' social reintegration.

Objectives: Transformation through a sustainable food system to provide healthy diets is essential for enhancing both human and planetary health. This study aimed to explain about sustainable diets and illustrate appropriate measurement of adherence to sustainable diets using a pre-existing index. Methods: For literature review, we used PubMed and Google Scholar databases by combining the search terms "development," "validation," "sustainable diet," "sustainable diet index," "planetary healthy diet," "EAT-Lancet diet," and "EAT-Lancet reference diet." For data presentation, we used data from National Health and Nutrition Examination Survey, 2017-2018, among adults aged 20 years and older (n = 3,920). Sustainable Diet Index-US (SDI-US), comprising four sub-indices corresponding to four dimensions of sustainable diets (nutritional quality, environmental impacts, affordability, and sociocultural practices), was calculated using data from 24-hour dietary recall interview, food expenditures, and food choices. A higher SDI-US score indicated greater adherence to sustainable diets (range: 4-20). This study also presented SDI-US scores according to the sociodemographic status. All analyses accounted for a complex survey design. Results: Of 148 papers, 16 were reviewed. Adherence to sustainable diets fell into 3 categories: EAT-Lancet reference diet-based (n = 8), Food and Agriculture Organization (FAO) definition-based (n = 4), and no specific guidelines but including the sustainability concept (n = 4). Importantly, FAO definition emphasizes on equal importance of four dimensions of diet (nutrition and health, economic, social and cultural, and environmental). The mean SDI-US score was 13 out of 20 points, and was higher in older, female, and highly educated adults than in their counterparts. Conclusions: This study highlighted that sustainable diets should be assessed using a multidimensional approach because of their complex nature. Currently, SDI can be a good option for operationalizing multidimensional sustainable diets. It is necessary to develop a Korean version of SDI through additional data collection, including environmental impact of food, food price, food budget, and use of ready-made products.
