In recent years, the number of construction projects carried out to repair and reinforce newly built structures and facilities has been on the rise compared to the number of new construction projects, accounting for more than 90 percents of all construction projects carried out by specialty construction companies. However, as some of the ordering parties fill out the required tasks incorrectly, the wrong information on construction bids is announced, and the specialty construction companies that hold a license and technology are unable to get the job at the right time. As such, it is critical to prevent unnecessary time and expense related to the correction of incorrect bid announcements by providing accurate information and definitions, because the tasks of each specialty construction work stipulated in the framework act of construction industry are vague. Therefore, the causes and problems were analyzed based on the correction cases of bid information, and a plan that can address the problem will be proposed. The result of this study can be utilized as fundamental data to achieve an institutional improvement in the bidding service for the specialty construction companies.

The regulation of business area was abolished to improve the competitiveness of the construction industry and the ability of general and specialty contractors to enter the mutual market. As the next step, the government is preparing for a reorganization of business type. If the impact of the abolishing of business area on the construction industry is analyzed, the result can contribute to determining the step by step application scope of the reorganization of business type. This study derived the business types having a high probability of the mutual market entry of general and specialty contractors. Then, the size of mutual market entry is analyzed. First, the connection between the general and specialty construction, and the similarities between the registration standards of general and specialty construction are analyzed. Based on the result, a general contractor can enter 15 business types of specialty construction, and the market size is about 78.8 trillion KRW. This is about 82% of the total contract cost of specialty construction during the year 2017 (about 96 trillion KRW). Next, based on the relevance of business contents, the market size when general contractors enter the specialty construction market is analyzed. As a result, the market size is about 24.7 trillion KRW, and this is about 13% of total contract cost of general construction during the year 2017 (about 190 trillion KRW). Based on the result of this study, there is a higher probability of the mutual market entry of general contractors into specialty construction than vice versa. However, the result of this study is based on the current contents of business types, registration standards, and construction data of before abolishing the regulation of business area. This is a research limitation. If the business contents and registration standards are changed in the future, the result could differ from the current result.

It is well known that a physician's personal characteristic affects his practice pattern. Furthermore, a physician's specialty has powerful influences on his practice pattern. However, despite the fact that specialization has received the most attention for its influence on physician's service behavior, few studies have been conducted on the variations of contents and volume of physician's services. This study has intended to identify factors influencing the practice variations according to various physician characteristics. There are some other evidences that medical care providers are different in using of health services and resources in Korea. Four physician characteristics were selected for the analysis, two demographical factors, age and sex, and two practice factors, place of practice and medical specialty. Also, three indicators of service amount (total amount of insurance claim bill, number of visits per case, number of prescriptions per case) were selected. From the pool of insurance claims for ambulatory care received by the Korean National Federation of Medical Insurance(NFMI), 84,898 cases were randomly sampled. In the meantime using physician database of NFMI, 613 general practitioners (GP), 107 regular family physicians (FP), 483 'grandfather' family physicians(GFP), and 1,157 specialist practitioners(SP) were randomly sampled. Their different practice contents were compared concerning the specialty, age groups, sex, and practice sites (urban-rural) Specialist physicians tend to provide more costly care than do generalists. General practitioners and family physicians usually make fewer following visits and prescriptions. Age is also the important factor in determining the amount of services, which is highest at the physician's age group of 40's. Female doctors and urban practitioners use much more resources than their counterparts respectively. Research findings suggest that physician's characteristics particularly the specialty can affect practice patterns and resource utilizations. Other characteristics such as age and sex are not controllable but physician's specialty is relatively easily controllable during the entire phases of policy implementation. This is all the more true in the individual's initial decision of his specialty. Specialization therefore should receive policymaker's attention for its potential influence on medical care utilization and health care expenditure.

The present study was conducted to assess relative importance of hospital attributes considered by patients with spinal diseases in choosing specialty or general hospitals. A total of 230 patients hospitalized with spinal diseases in sampled study sites, including 2 specialty and 2 general hospitals, participated in a self-administered questionnaire survey from April 26 through May 8 2007. Patients were asked to rate the degree of agreement on each of the 15 attributes on a 5-point Likert-type scale (1 : strongly disagree, 5 : strongly agree) for which they chose the hospital because of that specific attribute. Based on a Factor analysis, the attributes were grouped into 4 : facility and environment, accessibility, interpersonal factor, and credibility. Both patient groups from specialty (mean scale score ; 3.75) and general hospitals (3.62) commonly considered 'credibility' to be the most important attribute, followed by 'facility and environment (3.05 and 3.21).' Logistic regression analysis showed that men(Odds ratio(OR)=0.333) and those with monthly income of $\geq$ 4 million won (OR=0.298) were less likely to choose specialty hospitals. Age groups of 30 to 39 years old (OR=5.140) and $\geq$ 60 years old(OR=4.761), and professionals (OR=5.207) tended to choose specialty hospitals. Patients expressing more importance on 'facility and environment' attribute were less likely to use specialty hospitals (OR=0.571), whereas those emphasizing 'accessibility' were more likely to use specialty hospitals(OR=1.487). The findings of significant difference in patient's demographic characteristics and consideration in hospital attributes would contribute to have a better understanding on patient's choice behaviour and to develop strategy to improve patient's satisfaction.

This study analyzed the efficiency determinants of specialty construction companies by industry using the DEA model and the Tobit model. The analysis targets are 394 specialty construction companies as of 2022. As a result of analysis of efficiency determinants using 12 company characteristics as independent variables, the biggest problem for specialty construction companies was overall efficiency reduction due to rising labor costs. In addition, in a situation where construction companies' loan regulations are severe, the debt ratio was found to have a positive effect on efficiency. Company size had a different impact by industry, and the number of businesses held, credit score, and total capital turnover had an effect only on some industries. This study presents results that are an advance on existing research in that it strategically analyzes factors for improving the efficiency of specialty construction companies. However, it has limitations such as limiting the analysis to only specialty construction companies subject to external audit, insufficient number of companies subject to analysis by industry, and analyzing relative efficiency in the same category for each industry.
