Auction is widely used in allocation and procurement of resources due to its desirable properties: efficiency and revenue maximization. It is well-known, however, that auction may fail to achieve efficiency when allocative externalities exist. Such a result may happen in the auction of the resources that are very scarce, for example, radio spectrum. This is because allocation of the resources has effects on competition of the firms in the aftermarket, and thus a firm that utilizes the resources less efficiently may make a higher bid to lessen competition. This paper shows first that efficient allocation may not be achieved by auction even when the number of bidders is 2, while it is shown in the literature that auction may result in inefficient allocation when the number of bidders is greater than or equal to 3. There exist 2 firms, who make a bid to win the scarce resources that increase the value or decrease the production cost of their own product. After the auction ends, the firms engage in Bertrand competition on the Hotelling line. Inefficient allocation may happen even under the second-price auction rule, and it happens only when the firms are different in the initial value or the initial cost of their products as well as in the value of the auctioned resources. The firm who has been the leader loses a large portion of the market if it fails to win the auction, and thus makes a high bid even when the other firm can use the resources more efficiently. Allocative efficiency Pareto improves when the smaller firm's bid counts more than the leader's bid. This paper suggests a modified rule that the smaller firm wins the auction when its bid multiplied by some constant is greater than the leader's bid. The multiplier can be calculated from the market shares. It is equal to 1 when the two firms are the same, and is increasing in the leader's market share. Allocation is efficient in a strictly larger set of parameters under the modified rule than under the standard second-price auction rule.

This study set out to investigate the burden and needs of family members of ICU(Intensive Care Unit) patients facing a crisis situation of a family member being hospitalized in ICU and check their connections. Data were collected from May to October 2013. The subjects include 93 main family caregivers of patients hospitalized in ICU at four general hospitals in the B area for three days or longer. Collected data were put to t-test, ANOVA, Scheff$\acute{e}$ test, and Pearson's correlation coefficient analysis with the SPSS WIN 20.0 program. As a result, the family members of ICU patients scored mean 3.56 points(out of five) on burden and mean 3.58 points(out of four) on needs, recording a moderate or higher level in both the areas. There was significant difference(F=3.463, p=.036) in burden according to the general characteristics with the number of days in the hospital. There was significant positive correlation(r=.332, p<.001) between their burden and needs. Those findings indicate that an active nursing intervention to reduce the burden of the families of ICU patients in a crisis situation and check their needs will be able to mitigate the family crisis and further have positive influences on the recovery of ICU patients.

Purpose - Civil affairs are increasing in various forms, but civil servants who are able to handle them want to reduce the complaints and provide keywords that will help in the future due to their lack of time. While various ideas are presented and implemented as policies in solving civil affairs, there are many cases that are not policies that people can sympathize with. Therefore, it is necessary to analyze the complaints accurately and to present correct solutions to the analyzed civil complaint data. Research design, data, and methodology - We analyzed the complaints data for the last three years and found out how to solve the problems of Yongin City and alleviate the burdens of civil servants. To do this, the Hadoop platform and Design Thinking process were reviewed, and proposed a new process to fuse it. The big data analysis stage focuses on civil complaints - Civil data extraction - Civil data analysis - Categorization of the year by keywords analyzing them and the needs of citizens were identified. In the forecast analysis for deriving insights, - The case of innovation case study - Idea derivation - Idea evaluation - Prototyping - Case analysis stage used. Results - Through this, a creative idea of providing free transportation cards to solve the major issues of construction, apartment, installation, and vehicle problems was discovered. There is a specific problem of how to provide these services to certain areas, but there is a pressing need for a policy that can contribute as much as it can to the citizens who are suffering from various problems at this moment. Conclusions - In the past, there were many cases in which free traffic cards were issued mainly to the elderly or disabled. In other countries, foreign residents of other area visit the areas for accommodation, and may give out free transportation cards as well. In this case, the local government will be able to set up a framework to present with a win-win scenario in various ways. It is necessary to reorganize the process in future studies so that the actual solution will be adopted, reduce civil complaints, help establish policies in the future, and be applied in other cities as well.

The nursing education with evidence-based practice(EBP) should set a differentiated education strategy according to the level of the learner, so that the students experience it step by step and it leads them to be skilled. The purpose of this study was to integrate and operate the EBP in the fundamental nursing classes of the second grade students and to verify the effectiveness on improvement of EBP basic competency of them. A non-equivalent control group pretest-posttest design was used. The subjects were 108 students in the second year of nursing at the two universities. The experimental group participated in the class for 8 weeks and 24 hours during the 15-weeks, second semester 2016 and the control group participated in general fundamental nursing class. Data were collected proactivity in problem solving, future use of EBP, and critical thinking disposition instrument and analyzed using SPSS/WIN 23.0 program with Chi-square test, independent t-test. The experimental group had a significant increase in proactivity in problem solving and future use of EBP compared to the control group. However, there was no significant difference in critical thinking disposition between the two groups. Findings indicate that the fundamental nursing class used EBP was an effective lesson to improve proactivity in problem solving and future use of EBP, which is the EBP basic competency for the lower grader. Long-term efforts are needed to improve the EBP competence and critical thinking of nursing students by curriculum appropriate to grade-based goals of EBP.
