Domestic and foreign studies point to human factors as the main cause of unmanned aerial vehicle accidents, and HFACS is introduced as a technique to effectively analyze these human factors. Until now, domestic and foreign cases of analyzing the human factors of unmanned aerial vehicle accidents using HFACS were mainly targeted by military unmanned aerial vehicles, which can be used as an objective cause identification and similar accident prevention tool. In particular, identifying the focus of HFACS application considering the performance and operation conditions of domestic civilian unmanned aerial vehicles is expected to greatly help identify the cause and prevent recurrence in the event of an accident. Based on HFACS version 7.0, this study analyzed the accident investigation report data conducted by Korea Aviation and Railway Accident Investigation Board to identify the focus of HFACS application that can be used for domestic civilian unmanned aircraft accident investigations.

Massacres of civilians are being committed in the Russia-Ukraine war, and the war is becoming a long-term war due to a lack of support for reserve combat forces. Considering the reality that South Korea is experiencing a rapid population decline and is rapidly entering an aging society, we are at a point where the nature of the war with North Korea must change. Among them, if private security guards are placed under the control of the police as regular security and crime prevention personnel and used as an alternative resource for reserve forces to ensure the safety of wartime areas and residents and prepare for long-term wars, it will help preserve combat power and maintain sustainability.Regarding private security, considering Japan's further development, we compared it with ours and looked into ways to utilize it as a reserve force for a divided country. In a future where low birth rates will lead to a decrease in military strength, if private security guards are used in local security vacuums during peacetime and participate in local defense during wartime, it could help improve the Korean military's reserve force.

The technical regulation and conformity assessment procedure of our country on ICT equipments is currently required to have more innovation due to the request of main trade countries, the second phase conclusion of MRA, necessity of expansion of conformity assessment service market and demand of manufacturers. The world's leading advanced countries have already proceeded with innovation based on privatization plan. According to the comparative analysis of the level, it turned out that Japan obtained the highest level of privatization while South Korea ranked the lowest level. According to the research result of examination and certification ability of private institutions of our country, it turned out that our country is expected to have possibility of achieving higher level of privatization than that of the present. Moreover, according to the questionnaire survey conducted to the persons concerned regarding privatization direction, they gave positive response to all the indicated survey contents of privatization direction in terms of "delegation of certification services to private sectors (contracting-out)", "transformation of EMC into private voluntary standard" and "changeover of conformity assessment agent". However, from the view of acceptance and conflict model, it is estimated that starting from "delegation of certification services to private sectors (contracting-out)" seems to be the most advisable plan. Also, prior to privatization, it is required to improve relevant systems such as certification examiner system.

Private financing is playing an increasing role in public infrastructure construction projects worldwide. However, private investors/operators are exposed to the financial risk of low profitability due to the inaccurate estimation of facility demand, operation income, maintenance costs, etc. From the operator's perspective, a sound and thorough financial feasibility study is required to establish the appropriate capital structure of a project. Operators tend to reduce the equity amount to minimize the level of risk exposure, while creditors persist to raise it, in an attempt to secure a sufficient level of financial involvement from the operators. Therefore, it is important for creditors and operators to reach an agreement for a balanced capital structure that synthetically considers both profitability and repayment capacity. This paper presents an optimal capital structure model for successful private infrastructure investment. This model finds the optimized point where the profitability is balanced with the repayment capacity, with the use of the concept of utility function and multi-objective GA (Generic Algorithm)-based optimization. A case study is presented to show the validity of the model and its verification. The research conclusions provide a proper capital structure for privately-financed infrastructure projects through a proposed multi-objective model.

PFI(Private Finance Initiative) Project is carried to expand infrastructure effectively through participation of private investment. From the year 2005, the range is expanded not only industrial infrastructure such as made road, harbors and so on but living infrastructure such as school facilities, environmental facilities. For this reason BTL(Build-Transfer-Lease) system is mainly used in new private finance initiative project but in existing private finance initiative project BTO(Build-Transfer-Operate) system was used. BTL system is operated to judge fitness of private investment and classified into quantitative VFM(Value for Money) and qualitative VFM. In this research the estimation item of qualitative VFM which is hard to deduce the effect is created and after surveying of questionnaire in target of experts, relative importance and weight is established with AHP(Analytic Hierarchy Process). By estimating efficiency and benefit of quantitative VFM and qualitative VFM aspect effectively it is expected to support a rational making decision for operating BTL.

The opening of public data has been perceived as a critical factor in deciding a country's rise or fall. Since the global economic crisis, countries around the globe have expanded the supply of public data as a new growth engine to create significant economic effects. As a result, there has been a rising demand for a study on the influence of public data in the private sectors. This study attempted to achieve the following objectives. First, the effects of independent variables-system quality, information quality, information security, social influence, innovation and assistance by the public organization- on the intention to use the public data was examined. Second, the effects of the mediating variables - Perceived Ease of Use (PEU) and Perceived Usefulness (PU) - on the independent variables and intention to use (dependent variable) were investigated. Third, after selecting utilization type, frequency of public data usage and frequency of occupational & e-government service usage as moderating variables, their effects on the relationship between the independent variables and dependent variable (intention to use them in the private sector) were studied. It is expected that the study results would be useful in developing strategies aimed to utilize public data in the private sectors.

The evaluation of the financial viability of a privatized infrastructure project is complex because of the uncertainties involved due to the project's scale, long concession period and complexity. Use the BOT option valuation(BOT-OV) model, for evaluating the financial analysis of a privatized infrastructure project. This sophisticated for financial evaluation compared with a traditional NPV analysis.
