Post-traumatic stress disorder (PTSD) is a serious problem not only among workers who experience industrial accidents but also among workers who witness such accidents. Early intervention is needed to prevent prolonged psychological problems. There has been no study conducted regarding the psychological problems of and interventions for bystander workers in Korea. This study introduces the experience of intervention on psychological problems at the Busan Workers' Health Center workers who witnessed their colleagues' death. An investigation and an intervention were conducted according to the Korean Occupational Safety and Health Agency (KOSHA) Guide. In total, 21 individuals including indirect observers showed statistical differences on scores of the Impact Event Scale Revised and the Patient Health Questionnaire 9 after the intervention. Future interventions and research involving a larger sample size over a longer period are needed. The KOSHA Guide could be a useful tool for urgent psychological intervention in the event of major workplace disasters.

We aimed to understand various problems identified at waterscape facilities of gardens built at garden shows in Korea. The main purpose of the study is to understand which parts of waterscape facility built in gardens at garden shows are causing problems and whether these problems can be traced back from garden design phase or from local communities in charge of maintenance. Furthermore, we examined if such problems get more aggregated as time passes by and different garden shows have different types of problems. In this study, types of waterscape facilities examined are pond, waterway, wall fountain, water glass, trough, mist, Cascade, fountain, rain garden, waterfall. An analysis of the maintenance status of waterscape facilities introduced in the existing gardens confirmed that problems could arise in two main respects. One is due to poor maintenance by the organizers of the garden show, and the other is due to the poor design of waterscape facilities by the garden designer.

This study examines whether there is agency cost in a public R&D subsidy program by applying agency theory. If there is agency cost, the composition ratio of the government subsidy and the firm's own R&D fund would have a significant (-) effect on technological performance. Companies that received a public R&D subsidy in Korea from 2000 to 2009 were selected as a sample. Frequency analysis and multiple regression analysis were used. The independent variables was the ratio of public R&D subsidy cost to the Firm's own R&D cost, and the dependent variables were the number of patent applications and the number of patents registered. The control variables were firm size and R&D cost. The results show that there are agency problems in the government-sponsored R&D system. A future study is needed to examine how much agency problems deteriorate the efficiency of the system.

The death rate in the construction industry, which is more than twice that of other industries, increases the need to solve chronic safety problems. In a situation in which the safety management measures that have been maintained thus far are unable to reduce construction accidents, the introduction of smart construction safety technology (SCST) that reflects the 4th industrial technology is required for the safety management of workers. Large corporations or public institutions have introduced SCST and are operating pilot sites, but SCST is still in its infancy and there have yet to exist field data regarding necessity and effectiveness. In this study, the concept of SCST, which has still to be established, is defined, and the actual condition of SCST was analyzed through a survey. Through the analysis of the necessity of SCST introduction, convenience, and effectiveness before and after its application, problems such as problems from the field point of view as well as other factors hindering the introduction of such technology are derived in detail. In addition, an effective combination of technologies for safety management at the current level is determined and an activation plan is presented.

This study analyzes the current status of how to manage the national R&D program and the systematic problems of R&D planning, evaluation, and management, and then shows the strategy to support special agency of national R&D management for effective operation. Additionally, this study seeks to search for the macro methods to coordinate and to develop the roles and functions of special agency of national R&D management, and to promote efficiency and productivity of the National R&D investment. First of all, this study generally introduces the national R&D and surveys each special agency of national R&D management by analyzing the status of each agency charged by Ministry. Also, this study defines special agency of national R&D management by investigating each agency's status based on law and finds out the strategy to support special agency of national R&D management for effective operation. Each special agency of national R&D management is based on acts, administrative orders, or blanket contracts and takes whole charge of each National R&D program. The organization forms of special agency of national R&D management can be classified into two forms: One is a form to plan, to evaluate, and to manage the National R&D program and other is a form to research program together with the functions of planning, evaluation, and management. Therefore, this study defines special agency of national R&D management as "an organization, having a legal basis(acts, administrative orders), funded and charged by government for executing R&D planning, evaluation and management of R&D program." This study shows the strategy to operate special agency of national R&D management efficiently by analyzing each agency's current status and comparing each agency with each other. Moreover, every agency has a committee member pool, and the pool is classified well according to the fields of work and technology. Also, the special agency of national R&D management has its own organization to manage performances of program.

Foot-and-mouth disease (FMD) causes economic problems in livestock industry because of fast spread and inducing low productivity. FMD outbreaks occurred in South Korea over the period from 2000 to 2019. Vaccination is the most practical and effective means of controlling or preventing these outbreaks, and a national vaccination policy has been in place for all FMD-susceptible animals since 2010. To prevent and control of FMD, South Korea has been using vaccines imported from the United Kingdom, Argentina, and Russia. The Animal and Plant Quarantine Agency of South Korea oversees continuous quality control of imported FMD vaccines. FMD vaccines were evaluated characteristics, sterility, pH, inactivation, safety, potency test by Korean FMD vaccine standard assay (Test for National Lot Release). The 6 company vaccines (A~F) were used Test for National Lot Release by each method. We evaluated quality of each FMD vaccine from 2015 to 2019. All batch of vaccine showed good quality control and were passed the Test for National Lot Release. The serotypes of vaccine are increasingly changing to multiple vaccine because the FMD was outbreak by various serotype virus in South Korea. Furthermore, this data may be useful as a basis for ensuring the quality of FMD vaccines and for base data to manage them. Additional study is required to simple approach for rapid evaluation of quality and antigen content identification in vaccines.

The aim of this study was to investigate the current state of operation of information disclosure system in Busan Metropolitan Police Agency and to suggest recommendations for improvement. To achieve this goal, this study quantitatively analyzed the data on information disclosure claims (2010~2020.6), appeal cases (2010~2020.6), the disclosure rate of original documents (2014~2019) and so on. Furthermore, it examined how and how much information is announced in advance through the agency's homepage and the information disclosure portal site. Results show that the agency has various problems regarding information disclosure including the high rate of transferring information to other institutions, the low disclosure rate of original documents, the high rate of information released publicly only after an administrative appeal, a small number of information announced in advance, and a not user-friendly website. To solve these problems, this study proposes providing accurate information about the scope of information the agency and other related institutions own, expanding the disclosure of original documents, discovering more information to announce in advance, and enhancing the usability of the website.

Korean industries have been tend to depending upon historical information to control risk. The other hand, foreign industries have been identify risk factors using system safety techniques to predict future risk. One agency or person could not solve the problems of total safety system for improving productivity. In order to solve those problems, the production-safety group is necessary, and safety control system must be adapted by fitting to the production flow. This paper is present the methodology of driving occupational safety programs to increase productivity.

A High-degree Cubature Kalman Filter (CKF) is proposed to deal with the Strapdown Inertial Navigation System (SDINS) alignment problem. In-flight Alignment (IFA) is an effective method to compensate for attitude errors of the navigation system. While providing precise attitude error compensation, however, the external source aided alignment often creates a nonlinear filtering problem caused by a large misalignment angle. Introduced recently, Cubature Kalman Filter is a suitable technique for various nonlinear problems. In this paper, a higher degree CKF is applied to this accuracy-is-everything SDINS IFA problem. The simulation results show that the proposed technique outperformed a traditional nonlinear filter in terms of precision and alignment time.
