With the fee-based policy starting in 2001, the income statement of the contents providers shows that the contents sales is the number one portion, while the dotcom companies focusing on community sites have difficulties in diversifying business models. To overcome this problem, Freechal, a leader of community sites, employed a fee-based strategy for the first time in 2002, however, this attempt was failed because of a rapid decreasing number of community members. Many Internet companies too much relying on advertisement sales have been trying to turn into the fee-based business model, however, it is difficult for them to make an action plan owing to little research in this field. This paper provides an overview of community sites including their history, business models, and characteristics as well as suggests the implications from a Freechal case.

As the gaps become narrower in interconnection fee and volume rate, the MNOs began to introduce flat pricing for unlimited voice traffic competitively in Korea wireless telecommunication market : 'unlimited talks within intra-network' by the 1st operator, followed by the 3rd operator's 'unlimited talks over all networks'. As a result, subscribers tip in toward the third ranked operator and could bring a substantial change to steadfast market structure over the last decade in Korea. This paper aims to develop a simple economic model to analyze competition with flat pricing for unlimited voice traffic, and to check whether the pricing can be appropriate for the MNOs. The results show that MNOs already step in the necessary conditions to launch flat pricing for voice traffic. It also predicts that the MNOs compete with unlimited talk over all networks and set a single fee in an equilibrium. At present, the MNOs run virtually identical pricing for unlimited talk over all networks, considering their differentiation with respect to service quality, coverage and brand preference.

Open source software has a feature that offers its service by the subscription method without getting a license fee. Therefore, this business style needs a different form of estimate criteria from other proprietary software, which is paid by license fees and maintenance service fees. However, consumers, including the public sector, don't understand this feature. This problem has kept the open source software business from attaining prosperity. I would like to provide a model for the estimate criteria that can apply to the open source software business by investigating and developing various advanced research and market examples.

The number of nurses per bed at acute-stage hospitals is quite low in Korea compared with other OECD countries. In order to prevent the degradation of the quality of inpatient nursing services due to insufficient nurse staffs, the national health insurance introduced the differentiated nursing care fee system. This did not work as a motive for inducing the employment of nursing staff due to insufficient cost compensation. Because of insufficient nursing staff, family members have to stay with the patient or patients have to hire a personal care attendant. This increases the burden and cost to families. For the activation of hospitals without guardians, there should be policies for raising additional nursing staff such as standardizing jobs among nursing staff, particularly between nurses and nursing assistants, setting adequate standards of staffing in nursing according to medical service, substantiating the cost of nursing under the differentiated nursing care fee system, improving the medical fee system of hospitals without guardians including health insurance payment, supplying nursing staff stably through improving their working conditions such as providing child rearing services and salary increase, clarifying the qualification of personal care attendants working at acute.stage hospitals, developing indexes for assessing the quality of nursing care services, and monitoring for the management of uniform quality.

Purpose: This study focused on analysing costs per home health care nursing visit based on home health care nursing activities in medical institutes. Method: The data was collected in three stages. First, the cost elements of home health care nursing services were collected and 31 home care nurses participated. Second, the workload and caseload of home care nursing activities were measured by the Easley-Storfjell Instrument(1997). Third, the opinions on improving the home health care nursing reimbursement system were collected by a nation-wide mailing survey from a total of 125 home care agencies. Result: The cost of home health care nursing per visit was calculated as 50,626\. This was composed of a basic visiting fee of $35,090{\\}({\fallingdotseq}355$)$ and travel fee of $15,536{\\}({\fallingdotseq}15$)$. The major problems of the home care nursing payment system were the low level of the cost per visit, no distinction between first visit and revisits, and the limitations in health insurance coverage for home health care nursing services. Conclusion: This study's results will contribute as a baseline for establishing policies for improvement of the home health care nursing cost and for applying a community-based visiting nursing service cost.

Firms today have sought management effectiveness and efficiency utilizing information technologies (IT). Numerous firms are outsourcing specific information systems functions to cope with their short of information resources or IT experts, or to reduce their capital cost. Recently, Software-as-a-Service (SaaS) as a new type of information system has become one of the powerful outsourcing alternatives. SaaS is software deployed as a hosted and accessed over the internet. It is regarded as the idea of on-demand, pay-per-use, and utility computing and is now being applied to support the core competencies of clients in areas ranging from the individual productivity area to the vertical industry and e-commerce area. In this study, therefore, we seek to quantify the value that SaaS has on business performance by examining the relationships among firm strategies, SaaS technology maturity, and business performance of SaaS providers. We begin by drawing from prior literature on SaaS, technology maturity and firm strategy. SaaS technology maturity is classified into three different phases such as application service providing (ASP), Web-native application, and Web-service application. Firm strategies are manipulated by the low-cost strategy and differentiation strategy. Finally, we considered customer acquisition as a business performance. In this sense, specific objectives of this study are as follows. First, we examine the relationships between customer acquisition performance and both low-cost strategy and differentiation strategy of SaaS providers. Secondly, we investigate the mediating and moderating effects of SaaS technology maturity on those relationships. For this purpose, study collects data from the SaaS providers, and their line of applications registered in the database in CNK (Commerce net Korea) in Korea using a questionnaire method by the professional research institution. The unit of analysis in this study is the SBUs (strategic business unit) in the software provider. A total of 199 SBUs is used for analyzing and testing our hypotheses. With regards to the measurement of firm strategy, we take three measurement items for differentiation strategy such as the application uniqueness (referring an application aims to differentiate within just one or a small number of target industry), supply channel diversification (regarding whether SaaS vendor had diversified supply chain) as well as the number of specialized expertise and take two items for low cost strategy like subscription fee and initial set-up fee. We employ a hierarchical regression analysis technique for testing moderation effects of SaaS technology maturity and follow the Baron and Kenny's procedure for determining if firm strategies affect customer acquisition through technology maturity. Empirical results revealed that, firstly, when differentiation strategy is applied to attain business performance like customer acquisition, the effects of the strategy is moderated by the technology maturity level of SaaS providers. In other words, securing higher level of SaaS technology maturity is essential for higher business performance. For instance, given that firms implement application uniqueness or a distribution channel diversification as a differentiation strategy, they can acquire more customers when their level of SaaS technology maturity is higher rather than lower. Secondly, results indicate that pursuing differentiation strategy or low cost strategy effectively works for SaaS providers' obtaining customer, which means that continuously differentiating their service from others or making their service fee (subscription fee or initial set-up fee) lower are helpful for their business success in terms of acquiring their customers. Lastly, results show that the level of SaaS technology maturity mediates the relationships between low cost strategy and customer acquisition. That is, based on our research design, customers usually perceive the real value of the low subscription fee or initial set-up fee only through the SaaS service provide by vender and, in turn, this will affect their decision making whether subscribe or not.

Background: The purpose of this study was to analyze the increase in Grade of Nursing Management Fee of medical institutions and establish a reasonable government policy by examining which factors affect the increase of nurse staffing. Methods: Analyzing data collected from the Health Insurance Review & Assessment Service resource management department with targets of 1,104 medical institutions. The study period was 5 years from June 30, 2008 to June 30, 2013. SAS ver. 9.2 (SAS Institute Inc., Cary, NC, USA) was used for statistical analysis. The data was analyzed by a chi-square test and also conducted muiltivariate logistic regression analyses for variables of basic characteristics, human resource characteristics, and material resources. Results: Adjusted odds ratio (AOR) of the rise in Grade of Nursing Management Fee among other hospitals compared to hospitals owned by government or universities was 0.264. The AOR in hospitals established after November 2006 compared to those before June 1995 was 2.383. The AOR in Gangwon, Chungcheng South, and Jeolla South Provinces compared to Seoul was 0.084, 0.036, and 0.194, respectively. The AOR in hospitals with more than 6.75 specialists per 100 beds compared to those with less than 6.75 specialists per 100 beds was 7.514. The AOR in hospitals with more than 17.48 nurse per 100 beds compared to those with less than 17.48 nurse per 100 beds was 3.300. The AOR in hospitals with 50% to 75% bed utilization, 75% to 90% bed utilization and more than 90% bed utilization compared to those with less than 50% bed utilization was 5.428, 9.884, and 10.699, respectively. The AOR in hospitals with one magnetic resonance imaging (MRI) and more than two MRI compared to those with no MRI was 2.018 and 2.942, respectively. Conclusion: This result has showed policies to induce the rise in Grade of Nursing Management Fee among old hospitals and the incentive system for local medical institutions are needed. Also we need to develop a governmental policy for medium-small hospitals with low operation rate of beds and insufficient medical personnel and number of equipment in hospitals.

This paper first tries to analyze total sea transport costs for the transshipment in Busan Port in comparison with direct transport to 4 Chinese Ports, Dalian, Tinajin, Qingdao and Shanghai, based on vessel operation scenarios. The results found that the transshipment in Busan port for the 4 Chinese ports are more expensive than the direct calling to the 4 ports, which implies that Busan port needs to make compensation as an incentive to the carriers providing transshipment service to it in order to keep their royalty. For the compensation, it suggested a method of calculating the Container Terminal Facilities Leasing Fee to levy additional revenue by port authority.
