Purposes: The Specialty hospital designation policy had launched in 2011 and 110 designated specialty hospitals have been operating nationwide in 2022. This study was to estimate the market share of specialty hospitals for the specific diseases compared to other types of hospitals. Methodology: Data were derived from the National Health Insurance Claim data from 2018 to 2019. Subjects were all the inpatients with MDC(Major Disease Category) that specialty hospitals specialized in. A total of 34,231,387 claims were analyzed to estimate the market share. Findings: 90 specialty hospitals were responsible for 2.4 percent of inpatient care with specific diseases for specialty hospitals. There were regional variations in the market share of the specialty hospitals as the number of specialty hospitals in regions. Specialty hospitals' market shares were relatively high in burn(31.3%), ophthalmology(16.4%), obstetrics and gynecology(7.1%), alcohol(6.0%), joint(3.7%), spine(2.7%). After adjusting the number of inpatients per hospital, hospitals specialized in burn, alcohol, ophthalmology, breast, joint, obstetrics and gynecology, and hand replantation had treated more patients than tertiary hospitals. Practical Implications: Although specialty hospitals' market share was small, some types of specialty hospitals had an impact on the regional market as well as the national level market. To improve patients' accessibility to a specialty hospital, it is necessary to government supports non-specialized hospitals to change into specialty hospitals in certain fields and regions where the number of specialty hospitals is insufficient.

The mechanical properties of specialty cellulose fiber reinforced concrete and the contribution of specialty cellulose fiber to drying shrinkage crack reduction potential of concrete and theirs evaluation are presented in this paper. The effects of differing fiber volume fraction(0.03%, 0.06%, 0.08%, 0.1%, 0.15%, 0.2%) were studied. The results of tests of the specialty cellulose fiber reinforced concrete were compared with plain and polypropylene fiber reinforced concrete. Flexural performance(flexural strength and flexural toughness) test results indicated that specialty cellulose fiber reinforcement showed an ability to increase the flexural performance of normal- and high- strength concrete(as compared to plain and polypropylene fiber reinforced concrete). Optimum specialty cellulose fiber reinforced concrete were obtianed using 0.08% fiber volume fraction. Drying shrinkage cracking test results confirmed specialty cellulose fibers are effective in reducing the drying shrinkage cracking of normal and high-strength concrete(as compared to popylene fiber reinforced concrete).

Specialty cellulose fibers processed for the reinforcement of concrete offer relatively high levels of elastic modulus and bond strength. The hydrophilic surfaces of specialty cellulose fibers facilitate their dispersion and bonding in concrete. Specialty cellulose fibers have small effective diameters which are comparable to the cement particle size, and thus promote close packing and development of dense bulk and interface microstructure in the matrix. The relatively high surface area and the close spacing of specialty cellulose fibers when combined with their desirable mechanical characteristic make them quite effective in the suppression and stabilization of microcracks in the concrete matrix. The properties of fresh mixed specialty cellulose fiber reinforced concrete and the contribution of specialty cellulose fiber to the restrained shrinkage crack reduction potential of cement composites at early age and theirs evaluation are presented in this paper. Results indicated that specialty cellulose fiber reinforcement showed an ability to reduce the total area significantly (as compared to plain concrete and polypropylene fiber reinforced concrete.

Background: The purpose of this study was to determine the effectiveness of the specialty hospital system by comparing the medical use of inpatients who had artificial joint replacement surgery in specialty hospitals and non-specialty hospitals. Methods: This study utilized 2021-2022 healthcare benefit claims data provided by the Health Insurance Review and Assessment Service. The dependent variable is inpatient medical use which is measured in terms of charges per case and length of stay. The independent variable was whether the hospital was designated as a specialty hospital, and the control variables were patient-level variables (age, gender, insurer type, surgery type, and Charlson comorbidity index) and medical institution-level variables (establishment type, classification, location, number of orthopedic surgeons, and number of nurses). Results: The results of the multiple regression analysis between charges per case and whether a hospital is designated as a specialty hospital showed a statistically significant negative relationship between charges per case and whether a hospital is designated as a specialty hospital. This suggests a significant low in charges per case when a hospital is designated as a specialty hospital compared to a non-specialty hospital, indicating that there is a difference in medical use outcomes between specialty hospitals and non-specialty hospitals inpatients. Conclusion: The practical implications of this study are as follows. First, the criteria for designating specialty hospitals should be alleviated. In our study, the results show that specialty hospitals have significantly lower per-case costs than non-specialty hospitals. Despite the cost-effectiveness of specialty hospitals, the high barriers to be designated for specialty hospitals have gathered the specialty hospitals in metropolitan and major cities. To address the regional imbalance of specialty hospitals, it is believed that ease the criteria for designating specialty hospitals in non-metropolitan areas, such as introducing "semi-specialty hospitals (tentative name)," will lead to a reduction in health disparities between regions and reduce medical costs. Second, it is necessary to determine the appropriateness of the size of hospitals' medical staff. The study found that the number of orthopedic surgeons and nurses varied in charges per case. Therefore, it is believed that appropriately allocating hospital medical staff can maximize the cost-effectiveness of medical services and ultimately reduce medical costs.

The purpose of this study is to propose an effective leadership in the hospital management by analyzing the relationship of the effect of the specialty hospital CEO's leadership on the employees' organizational effectiveness as well as the customer orientation, and the mediation effects of the organizational effectiveness on the relation between hospital CEO's leadership and the customer orientation. The questionnaires of the survey targeting the 99 specialty hospitals were collected that 786 copies of them were utilized in analysis. The major outcomes of the research can be summarized as follows. Firstly, transformational leadership of specialty hospital CEO generally has the greater impact on the employees' job satisfaction, organizational commitment and turnover intention than his transactional leadership. Secondly, the most important sub-variable of specialty hospital CEO leadership affecting the organizational effectiveness of the employees are charisma of transformational leadership and contingent reward of transactional leadership. Thirdly, the sub-variable of specialty hospital CEO leadership which has the greatest impact on customer orientation of employees is the active management-by-exception of transactional leadership. Fourthly, the sub-variables in the organizational effectiveness such as job satisfaction, organizational commitment and the turnover intention of hospital employees play mostly the partial mediation role between the customer orientation of employees and the leadership of a specialty hospital CEO. This means that the more the organizational effectiveness of specialty hospital employees improves, the more the customer orientation does. Thus, specialty hospital CEOs need to pay attention to the sub-variables in organizational effectiveness so as to improve the customer orientation of the employees. To explore further the nature of the effect of hospital leadership in the future, apart form the variables of the organization effectiveness used in this study to improve the customer orientation of employees through the leadership of the specialty hospital CEO, the research to identify other factors which have greater influence and explanatory power will be needed.

Most of the construction works in domestic are not direct undertaking work, but by a contract method including subcontracting. Therefore, a general contractor for each project jointly carry out construction work with a specialty contractor for each engineering type. However, in terms of contract, this method is not a joint venture contract, but a subcontract. Accordingly, this system can cause various problems between the prime contractor and the subcontractor. Therefore, this study aims to extract and present the actual obstacle factors in terms of specialty contract company performing specialty construction work for construction project. The presented contents are expected to present the standard for the cooperation system that the prime contractor and the subcontractor can win-win.
