This study derived the policy implications and market strategies by analysis the e-book companies requirements & the CPND value chain structure, in order to revitalize the e-book market in Korea. Specifically, we examined the prospect of e-book market in Korea, current situations of production and distribution, awareness of service utilization and requirements for support policy with targets of 30 companies. As a research, the most needed item for e-book companies is 'PR and marketing support to enter and open the markets'(27%), which is the highest. 'Financial support such as labor costs and business expenses', 'support for retraining personnel to develop the expertise in respective fields' are followed and they account for 22%. Currently, the most effective support item is the external support program(35%) and funding power(30%) is followed. Unlike a paper book market, e-book is turned into a platform business in terms of the value chain. Based on these research content, e-book market activation and corporate competitive strategy was derived as follows : 1)literacy reinforcement about SNS marketing and e-pub3 authoring tool. 2)statistical DB construction of retail sales channels. 3)diversification of the billing system. 4)The quality of the e-book content certification.

In this study, we analyzed teachers' recognitions of the necessity of mathematical descriptive tests and their practices in the elementary schools. We then suggested several examples of improved formats of the mathematical descriptive evaluation. For analyzing teachers' recognitions and practices of mathematical descriptive assessment, we surveyed 104 elementary school teachers in Seoul. We collected the test items from the schools and analyzed them to find how they are practiced in the schools. The results were as follows. First, most elementary school teachers are basically recognizing the direction and the purpose of mathematical descriptive assessment. Second, the ratio of the descriptive test items was very low compared with the teachers' recognition of necessity of including descriptive items in the tests. Third, the teachers usually made the descriptive items with their colleagues using textbooks, test manuals for teachers, and the references that the office of education provided. Fourth, to enhance teachers' understanding of descriptive assessment, systematic training programs for teachers about the descriptive assessment should be continued. Finally, the office of education and research institutes should provide various types of test items and more teacher training programs on descriptive assessments.

Crash impact test is conducted to verify the crashworthiness of fuel tank. Success of the crash impact test means the improvement of survivability of crews by preventing post-crash fire. But, there is a big risk of failure due to huge external load in the crash impact test. The failure of crash impact test can result in serious delay of a entire rotorcraft development because of the design complement and re-production of the test specimens requiring a long-term preparation. Thus, the numerical simulations of the crash impact test has been required at the early design stage to minimize the possibility of trial-and-error in the real test. Present study conducts on the numerical simulation of phase I crash impact test using SPH supported by crash simulation software, LS-DYNA. Test condition of MIL-DTL-27422 is reflected on analysis and material data is acquired by specimen test of fuel cell material. As a result, the crash load on the skin material, overlap area and metal fitting is estimated to confirm the possibility of acquisition of the design load for the determination of the overlap area and adhesive strength.

This study was attempted to suggest future directions for nursing ethics education by analyzing research trends related to ethical conflicts among nurses and the current status of nursing ethics education. In four domestic databases, it was searched as a combination of words 'nurse', 'ethics', 'moral', 'bioethics', 'conflict', 'sensitivity', 'dilemma', 'issue', and 'value'. As a result, 591 papers were confirmed from 2000 to December 2021, of which 111 papers were finally analyzed. The status of nursing ethics education was analyzed for 184 out of 203 schools that operated a four-year bachelor's degree program registered with the Korean Accreditation Board of Nursing Education. As a result of the study, the number of studies related to ethical conflicts among nurses steadily increasing, and quantitative studies on nurses in general hospitals were the most common. The main keywords were identified as moral sensitivity, moral agony, ethical dilemma, and biomedical ethics awareness. Nursing ethics education was operated by 68% of universities as a major subject, and more than half of universities opened it in the first and second grades with one or two credits. As a result of this study, ethical conflicts experienced by nurses are increasing according to social change. Therefore, it is necessary for universities to further expand the proportion of nursing ethics education and to establish an educational model for each grade level for the continuity of the educational effect.

To participate in global carbon neutrality, the Korean government is also planning to carry out zero-energy building certification for all buildings by 2030 through the enforcement decree of the 'Green Building Support Act'. Accordingly, the government is providing various projects related to solar power generation, which are relatively close to life. In particular, roof-mounted photovoltaic power generation systems are attracting attention in terms of using unused space to produce energy without destroying the environment, but low power generation efficiency compared to other photovoltaic power generation facilities is pointed out as a disadvantage. Therefore, in this paper, to solve this problem, we propose an efficient solar panel angle variable system through research on the solar panel structure for single-axial solar tracking, and also consider the application environment of the roof-mounted solar power generation system. Suggests measures to prevent damage and secondary damage. In addition, it is judged that it is possible to control the solar panel based on ICT convergence and configure the accident prediction safety system to link the project-based education program.
