The purpose of this study is to clarify the perception and educational needs of international college students regarding the culture of college life. A questionnaire was given to international college students who are studying at universities in Korea. The results showed that international college students need to study about the culture of college life and had a perception that it is desirable to learn this through general education classes or freshman subjects after entering university. Also, the culture of college life can be divided into nine categories: bachelor's system; career and employment; university support centers and systems; interpersonal relations; departmental events; housing and living expenses; freshmen's events; exchange activities and programs; and cultural experience activities. International college students showed higher learning needs in order of career and employment; cultural experience activity; and bachelor's system. In addition, the characteristics of the learners showed different educational needs according to year of study and Korean language proficiency. The significance of this study is to specify the items of the culture of college life required for international college students, to measure the validity and reliability of these items, and to categorize the elements of the culture of college life.

The purpose of this study is to examine the effects of split ratings on earnings management through cost adjustments based on asymmetric cost behaviors. Using a sample of 2,027 Korean firm-year observations over the 2002-2019 period, we analyze whether a firm deliberately reduces discretionary costs, such as selling, general, and administrative (SG&A) expenses, to improve profits when it receives multiple ratings from credit rating agencies (CRAs). While examining earnings management incentives in the presence of split ratings, we also investigate the moderating effects of Chaebols, Korea's unique corporate governance structure. We find that split-rating firms show less stickiness in SG&A costs compared to non-split-rating firms when sales decrease. This result implies the deliberate reduction of discretionary costs to improve earnings in the presence of split ratings, which are more likely to change in future credit assessments. We also find that the incentives for earnings management of split-rating firms are limited in Chaebol firms, which have high levels of socio-economic surveillance and support affiliated firms through the internal market of corporate groups. This study contributes to existing research by identifying new determinants of cost behavior by using the framework of asymmetric cost behavior in relation to earnings management incentives.

Today's building and fire prevention codes are mostly prescriptive. Prescriptive codes are based on major fires in earlier years that created a need for specific building provision. These codes provide a minimum level of safety. As the general and engineering uses of computers have increased over the years, so has use of computers in the fire protection engineering. This has allowed fire protection engineers to develop alternative approaches to solve today's fire protection problems or to evaluate the performance of a specific fire safety goal. A performance based approach to building and fire codes involves the following: 1) identifying specific goals, such as, safely getting out of the building in 10 minutes, 2) obtain conceptual approval from authorities, 3) define performance level, 4) develop design solutions and identify tools such as, fire tests, models, or methods, to demonstrate that a design will meet the fire protection objective 5) test solutions, 6) present test method and results to the authorities. Some people in the fire protection community consider this to be nothing more than an intellectual exercise, while the others view it as a way to reduce expenses on large project$^4$ Others in fire protection community view this as a way to refine the design process to design fire protection systems to better protect the fire hazards. This paper will focus on application of these tools, specifically computer fire models, to actual cases such as: design of a smoke control system heat transfer analysis and egress of building occupants during potential fires.

The size of the government is one of the most fundamental debates of open economies. In any economy, government plays an important role, but a pertinent level of economic prosperity has never been obtained in history without government. Therefore, the objective of this paper investigates the association of government size, economic volatility, and institutional quality for 182 economies from the time period 1996-2016 is collected from the World Bank database. GE is defined as the General government's final consumption expenditure. Health expenditure is represented by HE. Government expenditure on education is denoted by EDUEXP. The economic volatility is measured by the rolling standard deviation of GDP per capita growth rate, Population growth, Trade openness, GINI represented Gini index which measures the degree to which the income distributed or consumption expenses among citizens deviates from a perfectly equal distribution. The results proposed that economic volatility has a significant effect on government size and institutional qualities. Moreover, the paper extends the investigation by finding the link between economic volatility with government health and education expenditure separately. The policy implication drawn from this analysis is that controlling economic volatility may reduce the size of government and also significantly affect health and education expenditures.

To develop a shipping company insolvency prediction model, we sampled shipping companies that closed between 2005 and 2023. In addition, a closed company and a normal company with similar asset size were selected as a paired sample. For this study, data of a total of 82 companies, including 42 closed companies and 42 general companies, were obtained. These data were randomly divided into a training set (2/3 of data) and a testing set (1/3 of data). Training data were used to develop the model while test data were used to measure the accuracy of the model. In this study, a prediction model for Korean shipping insolvency was developed using financial ratio variables frequently used in previous studies. First, using the LASSO technique, main variables out of 24 independent variables were reduced to 9. Next, we set insolvent companies to 1 and normal companies to 0 and fitted logistic regression, LDA and QDA model. As a result, the accuracy of the prediction model was 82.14% for the QDA model, 78.57% for the logistic regression model, and 75.00% for the LDA model. In addition, variables 'Current ratio', 'Interest expenses to sales', 'Total assets turnover', and 'Operating income to sales' were analyzed as major variables affecting corporate insolvency.

Purpose: This study was aimed to estimate nursing cost for hemodialysis of tertiary hospitals using Resource Based Relative Value Scale(RVRBS). Method: First, we calculated nursing workload of the each hemodialysis-nursing behaviors compared with basic nursing behavior(check vital sign) for the most severe hemodialysis patients in general hospitals. Second, we measured each spent time according to each nursing behaviors. Third, we computed Resource Based Relative Value(RBRV) scores and nursing expenses of each 14 nursing behavior for hemodialysis. Finally, we estimated nursing cost of each hemodialysis-behavior for the most severe hemodialysis-patients in general hospitals. Result: The mean RBRV scores for each nursing behaviors were from 218.9 to 383.9 points. The highest RBRV socres were 383.9(Complication during hemodialysis). The Nursing behavior that spent the most time was "access the vascular( 31.7 minutes)". Nursing cost per hemodialysis for the patient with severe condition was estimated 63,455(won). Conclusion: Total average workload was 347.6 points and total spent time was 306.5 minutes for 14 hemodialysis nursing behaviors provided to severe patients. There were clear differences in nursing workload and cost according to patient's severity-mild, moderate and severe class.

Unlike profit-seeking businesses, hospitals provide medical services to promote the public good in a way, and they need a reform of management to ensure sustainable growth in fast-changing medical environments. The key to the managerial reform is enhancing efficiency, and inefficient managerial practices and factors affecting that should be grasped first of all to boost the efficiency of hospital management. But evaluation methods that are prevalent in the private sector are hardly applicable to hospitals. The purpose of this study was to assess hospital efficiency by using a data envelopment analysis(DEA). The 2006 data on 74 residency training hospitals with 500 beds or more were analyzed. The selected input variables included the number of bed, the number of doctors, the number of nurses, the number of medical technicians, personnel expenses, management cost and materials cost. And the selected output variables were the yearly number of outpatients, the yearly number of inpatients, the number of operation cases and earnings. In addition, the influence of the type of hospital establishment, location, the year of foundation and the type of hospital on hospital efficiency was checked as well.

According to the increase of the proportion of aged people, the medical demand for a senile chronic disease has been increased; therefore, aged people call for a geriatric hospital for special geriatric medical service. The main purpose of this study was to analyze the general characteristics and financial status of geriatric hospitals. For the study, a questionnaire was designed and sent to the geriatric hospitals to fill out the patient statistics, number of headcount by department, etc. to find out the stability, profitability, activity and so on financial statements of the hospitals were analyzed. The major findings of this study were as belows. 1. The ratio of the medical expenses to the revenue of the geriatric hospitals is much lower than acute care hospitals. But the probability of bankruptcy is higher due to the high ratio of the liabilities therefore it is required to stabilize the financial position by donating more money. 2. Government budget for the elderly people is not enough. To support the geriatric hospitals by going subsides, government should increase the budget. 3. Portion's of the patient of the geriatric hospitals are government support patient. Since the government doesn't pay the medical charges quickly, geriatric hospitals have a serious cash flow problem. Therefore, it is required that government is to prepay the bill. 4. Since geriatric hospitals treat elderly patient and most patients are government support patients, geriatric hospitals can be said to operate under the strict. 5. When we introduce the daily medical charge, the self-liability will be reduced on approximately 50% of current. This affection will bring a huge progressing financial structure to the medical profit of the geriatric hospital, and also patient family will feel less economical burden.
