This study was performed to identify factors affecting the profitability of private hospitals in Korea different and to make informations that could be very helpful to hospitals in improving profitability. Data used in this study were collected from 112 hospitals with complete general data of present conditions as well as financial statements(balance sheets, income statements). They were chosen from hospitals that passed the standardization audit undertaken by the Korean Hospital Association from 1998 to 2001 for the purpose of accrediting training hospitals. The dependent variables were used operating margin to total assets and operating margin to gross revenues as proxy indicators for profitability. The independent variables were ownership type, location, bed size, period of establishment, debt to total assets, current ratio, fixed ratio, total asset turnover, average length of stay, bed occupancy rate, admission ratio of outpatients, personnel costs per adjusted inpatient, and fiscal years. The factors had significantly positive effect on operating margin to total assets and operating margin to gross revenues were bed size, total asset turnover. And the factors had significantly negative effect on operating margin to total assets and operating margin to gross revenues were period of establishment, debt to total assets, average length of stay, personnel costs per adjusted inpatient. The adjusted $R^2$ of multiple regression equation was 25.2%, 21.4% respectively. It is very important for private hospitals to improve profitability by raising total asset turnover, and reducing debt to total assets, average length of stay, and personnel costs per adjusted inpatient using the rational and efficient business strategy.

The purpose of this study was the acquisition of the optimum scale of the apportionment of standard & high-class bed for the maximum profit representative of the desire of customers in a General Hospital with 1,100 beds located in Seoul. This investigation was proceeded by the analysis of the result of the simulation with the survey of both the patients' needs for bed and the degree of the medical service by the grade of the ward. And finally the consequence was obtained as follows: 1. The result of the investigation of the inpatients' preference for the grade of ward classes shows that a private ward reflected 4.3 percent, a semi-private ward 1.7 percent, a three-bed ward 0.1 percent, and a ward with six beds 93.9 percent each other. 2. A questionnaire poll was paralleled of service terms of a medical doctor and a nurse by ward class, the data were used for the standard of the allotment of labor cost by the ward class. The poll shows that the service tenn of a medical doctor and a nurse based on a ward with six beds by ward class showed 1.7 times in internal medicine and 1.9 times in surgery at a private ward; 1.4 times in internal medicine and 1.7 times in surgery at a semi-private room; and 1.2 times both in internal medicine and in surgery at a three-bed ward 3. The resultant findings revealed the most profit per bed and per patient in a private ward. However, an analysis of profit with a standard of unit area by ward class represented a higher profit in both the internal medicine and the surgery semi-private ward than other ward classes. 4. The result of the analysis through simulation based on the data of the prime cost per the ward class proved the optimum scale of the distribution of beds by class as follows: sixteen beds of the internal medicine and twenty three beds of the surgery in the private ward; two hundreds and two of the internal medicine and one hundred and ninety eight of the surgery in the semi-private room; three of both the internal medicine and the surgery each other in the three-bed ward; one hundred and ninety eight of the internal medicine and two hundred and fifty two of the surgery in the ward with six beds. The result of this research exhibits that the income and expenditure of the hospital could be improved by changing parts of wards into private ones(containing the maximum profit per a unit of width) in case the scale of the number of beds is reset with the consideration of the profit per the unit width. In the near future it's strongly expected that the research for the more scientific standard of the allotment of labour cost by ward class and for definition of the optimum scale of the number of beds that actualize the maximum profit with the change of the three elements of the prime cost: cost of materials; labor costs; management expenses.

Background: The national Public-Private Mix (PPM) tuberculosis (TB) control project provides for the comprehensive management of TB patients at private hospitals in South Korea. Surveillance and monitoring of TB under the PPM project are essential toward achieving TB elimination goals. Methods: TB is a nationally notifiable disease in South Korea and is monitored using the surveillance system. The Korea Centers for Disease Control and Prevention quarterly generates monitoring indicators for TB management, used to evaluate activities of the PPM hospitals by the central steering committee of the national PPM TB control project. Based on the notification date, TB patients at PPM hospitals were enrolled in each quarter, forming a cohort, and followed up for at least 12 months to identify treatment outcomes. This report analyzed the dataset of cohorts the first quarter of 2016 through the fourth quarter of 2017. Results: The coverage of sputum, smear, and culture tests among the pulmonary TB cases were 92.8% and 91.5%, respectively. The percentage of positive sputum smear and culture test results were 30.7% and 61.5%, respectively. The coverage of drug susceptibility tests among the culture-confirmed cases was 92.8%. The treatment success rate among the smear-positive drug-susceptible cases was 83.2%. The coverage of latent TB infection treatment among the childhood TB contacts was significantly higher than that among the adult contacts (85.6% vs. 56.0%, p=0.001). Conclusion: This is the first official report to analyze monitoring indicators, describing the current status of the national PPM TB control project. To sustain its effect, strengthening the monitoring and evaluation systems is essential.

This research is aimed at analyzing and understanding the perception and attitudes of inpatients in a general hospital in Seoul towards the activation of private health insurance. Survey was conducted against 231 inpatients, results of which were analyzed in the methods of frequency analysis, chi square test, and logistic regression. The results are summarized as follows; First, better-educated population who finished college education at least, higher-income population, and people who had more knowledge about private health insurance showed more perception about activation of private health insurance. Second, better-educated population who finished college education at least, higher-income population, those who are insured in existing private insurance, oncological patients, and people who had more knowledge about private health insurance showed more positive attitude towards private health insurance paying for actual damages, long-term care insurance, and income security insurance. Third, age and education were the factors affecting perception about activation of private health insurance. The older the age is, perception was 1.035 times positive towards activation of private health insurance, and those who finished college education or above showed 3.148 times positive perception towards the same. Forth, surgical patients showed 1.087 times more positive attitude towards private health insurance paying for actual damages than internal medicine patients, while oncological patients showed 2.314 times more positive attitude than internal medicine patients. Further, understanding on the activation of private health insurance was 6.014 times higher in the higher understanding group than in the lower understanding group. Intention to use long-term care insurance was 2.692 times stronger in the male group than in the female group, and 3.616 times stronger in the oncological patients group than in internal medicine patients group. Further, understanding on the activation of private health insurance was 3.881 times deeper in the higher understanding group than in the lower understanding group. Intention to use income security insurance was 3.185 times stronger in those who have academic background of under the high school than those over the college, and 4.175 times higher in the group those whose monthly average income is over 4 million won than those under 4 million won. Also, intention to use income security insurance was 4.323 times higher in the group those who are insured by existing private insurances than those who are not insured by those insurances and it was 5.234 times higher in the group of oncological patients than in the group of internal medicine patients. Further, intention to use income security insurance was 3.559 times higher in the group those who thought that out-of-pocket money of the National Health Insurance is too much to bear than those it is quite endurable. Understanding on the activation of private health insurance was 4.875 times deeper in the higher understanding group than in the lower understanding group. There were some suggestions could be made based on the results of this research. First, reinforced publicity and education is needed for the low-educated or low-income group, as there are gaps in the understanding on the activation of private health insurance depending on the degree of education and income. Second, government should prepare administrative complementary measures to solve the problem of adverse selection by the consumer which is foreseen when private health insurances are activated. Third, government should suggest the desirable course of development of private health insurance items to ensure efficient use of enormous fund of private insurance market for health security of the people. Further, institutional complementary measures are needed to convert existing cancer insurances or specific disease insurances to private health insurances paying for actual damages guaranteeing against every kind of disease. Forth, it judged that, not only private health insurances paying for actual damages, but also long-term care insurances and income security insurances are prospective as fields to create fresh demand for insurance industry.

Objective : This prospective study sought to verify the stability of three types of short implants measuring 7mm or less. Materials and methods : Implants measuring 7mm or less were placed in patients at multicenter dental clinics in Korea, China, Taiwan, and Singapore. Initial stability, intraoperative and postoperative complications, crestal bone loss, and survival rate of the implant were prospectively evaluated. Results : The primary stability of a 6-mm implant was lower than that of a 7-mm implant. The marginal bone loss of short implants measuring less than 7mm was minimal. Complications such as wound dehiscence, implant mobility, and peri-implant mucositis developed, and these were associated with initial implant failure. The short-term survival rate of 6-mm implant was 93.7%, and that of 7-mm implant, 96.6%. Conclusion : Short implant for the mandible with insufficient height for the residual ridge can be selectively used. Poor primary stability and wound dehiscence can cause osseointegration failure and alveolar bone loss.

Purpose / Approach : This study aims to analyze the level of public service motivation and its antecedents by using survey data of 1,498 professional employees in public and private hospitals. Findings : Among job-related, organization-related, and socialization-related factors of professional employees, the socialization factors have a strong effect on individual's overall and the four sub-dimensions of public service motivation. While the effect of organizational identification is prominent in the public hospital, professional identification is more powerful in the private hospital. Person-job fit and person-organizational value fit also play a significant role in determining public service motivation. Organizational vision salience in public hospital has negative effect on public service motivation and attraction-to-public-service dimension. The significant determinants and its effect size are different according to hospital type and each sub-dimension of public service motivation. Practical Implications : The empirical findings show that individual's level of public service motivation in hospitals could be enhanced through the interaction between individual and their organization, and various organization-related factors. Further implications of the study are discussed from human resource management perspective in hospitals.

This study examined market size of private health insurance premium and individual characteristics associated with the market size change in Korea, using wave 1 (2008) and wave 2 (2009) of Korea Health Panel. The market size was 24.4 trillion Korean won in 2008 and 26.9 trillion in 2009. The increase rate of private health insurance premium among those who were the elderly, single, or the poor was higher than that among their counterpart respectively. Health status and utilization were insignificant in determining the increase rate of private health insurance premium. These findings were more obvious among the uninsured in 2008 than among the insured in 2008. The increase of private health insurance premium in Korea imply the increase of willingness-to-pay for health risk through private sector. The authors suggest policy intervention for accessability to health care for the underprivileged and weak through enlargement of Korean social health insurance benefit.

Skeletal anchorage-assisted upper molar distalization has become one of the standard treatment modalities for the correction of Class II malocclusion. The purpose of this study was to analyze maxillary molar movement patterns according to appliance design, with the simultaneous use of buccal fixed orthodontic appliances. The authors devised two distinct types of midpalatal miniscrew-assisted maxillary molar distalizers, a lingual arch type and a pendulum type. Fourteen patients treated with one of the two types of distalizers were enrolled in the study, and the patterns of tooth movement associated with each type were compared. Pre- and post-treatment lateral cephalograms were analyzed. The lingual arch type was associated with relatively bodily upper molar distalization, while the pendulum type was associated with distal tipping with intrusion of the upper molar. Clinicians should be aware of the expected tooth movement associated with each appliance design. Further well designed studies with larger sample sizes are required.
