In the developed countries, the private investigation system which is part of private security has developed together with police, and OECD countries except South Korea has developed the private investigation system establishing by the Private Investigation ACT. In Korea, there was several attempt to establish the Private Investigation ACT but it was not accomplished because of private security circumstances. In this study, the chapter Iis introduction, theoretical background is in chapter II, chapter III is the operation of private investigation of the developed countries, analysis and direction of the Private Investigation ACT in chapter IV, and conclusion in chapter V. To introduce the private investigation system, it is required to discover the problem of the Private Investigation ACT mentioned in this article and to develop the private investigation system by collecting the opnion of citizen, academic world, and the related agency. It is necessary to associated interest and effort of citizen, academic world, and the related agency for introdection of the private investigation system.

Otters, designated as Class I endangered wildlife due to population declines resulting from urban development and stream burial, have seen increased appearances in freshwater environments since the nationwide ban on stream filling in 2020 and the implementation of urban stream restoration projects. There is a pressing need for scientific and strategic conservation measures for otters, an umbrella and vulnerable species in aquatic ecosystems. Therefore, this study predicts potential otter habitats using the species distribution model MaxEnt, focusing on Hwangguji Stream in Suwon, and proposes conservation strategies. Otter signs were surveyed over three years from 2019 to 2021 with citizen scientists, serving as presence data for the model. The model's outcomes were enhanced by analyzing 'river nature map' as a boundary. MaxEnt compared the performance of 60 combinations of feature classes and regularization multipliers to prevent model complexity and overfitting. Additionally, unmanned sensor cameras observed otter density for model validation, confirming correlations with the species distribution model results. The 'LQ-5.0' parameter combination showed the highest explanatory power with an AUC of 0.853. The model indicated that the 'adjacent land use' variable accounted for 31.5% of the explanation, with a preference for areas around cultivated lands. Otters were found to prefer shelter rates of 10-30% in riparian forests within 2 km of bridges. Higher otter densities observed by unmanned sensors correlated with increasing model values. Based on these results, the study suggests three conservation strategies: establishing stable buffer zones to enhance ecological connectivity, improving water quality against non-point source pollution, and raising public awareness. The study provides a scientific basis for potential otter habitat management, effective conservation through governance linking local governments, sustainable biodiversity goals, and civil organizations.

Assessing local government performance has become a crucial issue in recent years. This paper addresses the satisfaction level of local government public service, which is defined as a degree of the results or the impacts of the local government public service delivery on the citizen's needs, demands and expectations. The satisfaction level of local government public service can improve decisions made by local government managers, and enhance accountability of local government to the citizens they serve. This study focuses especially on the various aspects of administrative systems in a local government and developed a systematic survey for their performance. Explanations for the evaluation items and the analysis of survey are discussed throughout the paper.

Nowadays obesity has been become a serious social issue. Many researches are trying to find the root cause of obesity. Obesity causes various kinds of disease and safety accidents in work places. Thus, the main objective of this study is to analyze obesity index of citizens in Seoul which is a metropolis of Korea and a densely populated district. In order to analyze a detailed somatotype of citizens, age groups are divided into 30-34 years, 35-39 years, 40-49 years, and 50-59 years according to gender respectively. The result of this study can be applied to the comfortable and appropriate design for workers.

The Global IT revolution is growing rapidly. Government and business have to be ready to meet the increased demand for effective and secure online services. With the E-Government practicing, day-by-day the public demand is also increasing simultaneously. Now this present moment, one of important research part is secure E-Voting for E-Government service, but for this important factor or Government Issue, it needs information privacy for secure information transaction of citizen’s opinions and secure authentication. This paper has analyzed several approaches E-voting protocols, those are implemented with many digital signature mechanism and maintained many types of cryptographic rules, which are main factor for information privacy. In this paper we have discussed them with a view to voter anonymity and protection from manipulations. The paper then developed an algorithm designed to guarantee anonymity of the voter and to avoid the risk of manipulation of votes. In this paper the proposed algorithm is based upon the strict separation of voter’s registration and submission of votes, which means that certain information has to be stored on a secure storage media.

It is necessary to build countermeasure for the reduction of flood damage, such as the analysis of shelter activities of local residents and the publishment of flood informations. The control factors for mental refuge activity by the questionnaire survey were classified and estimated into two categories: internal and external ones. Furthermore, the optimal time for refuse activities related to flood risk was derived by hydraulic simulation. The shelter activities considering inundation depth will serve citizen's consensus by exercise, it would aid to support the activities to minimize flood victims.

A company is liable for its products and has the responsibility to make good on any loss or damage incurred by the user of its product. The purpose of the Product Liability Act(PLA) is to protect consumers against damage caused by defective products, and contribute to the safety of the citizen's life and the sound development of the national economy by regulating the liability of manufacturers, etc. for damages caused by the defectiveness of their products. In this study, the cognition levels of consumers and producers for PLA were surveyed. The cognition levels of four factors of acknowledgement, comprehension, necessity and impact for PLA were assessed. The results were as follows : i) Acknowledgement and comprehension levels of consumer were assessed low but they assessed necessity and impact of PLA high; ii) Producers assessed necessity and impact of PLA higher than their acknowledgement and comprehension levels; iii) Overall cognition levels of producers were higher than those of consumers.

Today, the times of knowledge-intelligence made changes of the ordinary life of citizens society, and also changed greatly the circumstance of leadership in the military. The times of knowledge-intelligence changed the circumstances of national security and the features of warfares, and also make affecting decisively to senses and style of new who were servicing in the military. In order to response effectively against the changes of those leadership circumstances, senior level leadership should be understand in depth human psychology and battlefield circumstances in the dimension of policies and strategies, and should be executed their leadership. In this thesis, I reviewed the concept and vision of senior level leadership theories and cases about traits and roles In addition, I suggested development options for senior level leadership such as (1) high charactenstics and professionalism, (2)educational center of military for advanced democratic citizen and leadership, (3)execution of leadership in psychological leadership, (4)development of leadership needed in the battlefield Finally, the current military senior level leadership should be changed from one-side and authority style to the change-orientated style, which could believe and participate by themselves.
