「연구실안전법」에 따르면 기업부설연구소 또는 연구개발전담부서의 경우 연구실 안전과 관련한 기술적인 사항에 대하여 연구주체의 장을 보좌하고 연구실책임자 등 연구활동종사자에게 조언·지도하는 업무를 수행하는 연구실안전환경관리자를 지정할 필요가 없기 때문에 연구실 안전관리를 수행할 수 있는 전문가가 없는 것이 현실이다. 기업부설연구소 또는 연구개발전 담부서에 있어서 「연구실안전법」에 따른 연구실안전환경관리자의 지정에 관한 내용을 검토하고 그 방안을 제시하였다.

Each country tries to prevent major industrial accidents at industrial sites, such as fire and explosion as well as poisoning incidents, and regulation of the management of chemicals is being enhanced in all sectors. In particular, in the case of laboratories, a variety of chemicals have been developed and handled in accordance with the development of science and technology. On the other hand, the accident probability at laboratories is higher than at industrial sites, because many different kinds of chemicals are handled in the laboratory but in very small amounts and chemical, physical, and biological studies have been carried out in limited spaces. Recently, the accident probability at laboratories was found to be higher as convergence/integration studies were carried out beyond the academic arena. Therefore, in this study, a survey of chemical management was conducted to prevent accidents due to chemicals targeting the laboratory safety coordinator using the FGI (focus group interview) method. The building plan of a chemical management system was suggested based on the results of the survey.

Authentication and access control are essential requirements for the information security of distributed environment. Delegation is process whereby an initiator principal in a distributed environment authorizes another principal to carry out some functions on behalf of the former. Delegation of access rights also increases the availability of services offer safety in distributed environments. A delegation easily provides principal to grant privileges in the single domain with Role-Based Access Control(RBAC). But in the multi-domain, initiators who request delegation may require to limit the access right of their delegates with restrictions that are called delegate restriction to protect the abuse of privilege. In this paper, we propose the delegation view as function of delegation restrictions. Proposed delegation view model not only prevent over-exposure of documents from granting multiple step delegation to document sharing in multi-domain with RBAC infrastructure but also reduce overload of security administrator and communication.

하천관리청은 유량변동이 큰 환경에서도 평상시 하천의 기능을 유지하고 안정적인 용수공급이 이루어지도록 하천수 허가관리를 수행하고 있다. 이때, 하천수 사용허가 검토시 기준으로 사용되는 유량은 자연상태의 기준갈수량에서 하천유지유량을 감안하여 적용하고 있는데, 이는 하천유량의 변동에도 최대 용수수요를 만족할 수 있게끔 관리하기 위한 것으로 최대 사용량일 때의 물의 과부족을 계산하여 허가 여부를 결정한다. 본 연구에서는 Park et al.(2016)이 제안한 시기별(홍수기/이수기, 비관개기/관개기 고려) 하천수 사용허가 기준유량 설정방법을 기반으로, 수질오염총량제(Total Maximum Daily Loads, TMDLs)에서 적용하는 안전율(Margin of Safety, MOS)의 개념을 접목하여 허가기준유량의 불확실성을 정량적으로 고려할 수 있는 방법을 제시하였다. 허가기준 유량은 수문모델에 의해 자연상태의 모의유량을 유황분석하여 도출하게 되므로 유량의 연도별 변도성(Margin of Variability, MOV)과 예측모델 매개변수의 불확실성(Margin of Uncertainty, MOU)을 고려하는 Walker Jr.(2003)의 안전율 산정방법을 적용하였다. 본 연구에서는 금호강 유역을 대상으로 시기별 자연유량 산정시 고려한 SWAT 모형결과를 기반으로 하였으며, 모의자료의 변이계수를 산정하여 시간적 변동성에 의한 불확실성을 도출하고 SWAT-CUP모형을 활용하여 모형의 불확실성을 도출하여 안전율을 계산하였다. 단, 기준갈수량이 허가기준유량으로 사용되는 기간(1월 1일~3월 31일)에는 안전율까지 고려할 경우 지나치게 보수적이라고 판단되어 적용에서 제외하였다. 본 연구에서 제안된 불확실성을 고려한 하천수 관리방법론은 시기별 하천수 허가기준유량 설정에 대한 의사결정자들의 판단을 지원하는데 기여함으로써 정책적 활용도를 높일 뿐만아니라 탄력적인 하천유량관리를 위한 기초연구로 활용될 수 있을 것이며, 타 분야 기술과의 융합이라는 점에서도 의의를 가질 수 있을 것으로 생각된다.

This paper shows survey result on safety management status of laboratories in Korea. In Korea, many studies and reports on laboratory safety have been published since the ministry of education, science and technology (MEST) enforced the Act on Establishing a Safe Environment of Laboratories (Lab Safety Act) in 2006. The MEST has surveyed status of safety management in institutions subject to Lab Safety Act in 2008 and 2010. According to the survey result, safety management status of universities and colleges has been improved on several factors such as establishment of safety manual and implementation of safety inspection; while the number of safety managers of universities and colleges have increased. However, the difficulties in performing duties of safety managers has increased because the number of exclusive safety managers has decreased. This paper identifies the similarities and differences between Occupational Safety and Health Act and Lab Safety Act on assignment and duties of safety managers; therefore, this paper suggests a standard to determine the number of safety managers and decide whether or not their duties should be exclusive. Besides current standard that is based on the number of researchers, the number of individual laboratories should be considered. The new method would be helpful to determine the number of exclusive safety managers because the amount of safety managers' duties generally do not depend on only the number of people who may be exposed to any risk but also the number of facilities that may be cause of any accident.

Recently, the reagent in the laboratory can not only confirm the internal environment through the sensor but also check the status inside the reagent cabinet in real time. Also, if an abnormality occurs in the inside of the reagent cabinet, a serious accident may occur. To solve these problems, this paper proposes a reagent monitoring system that integrates reagent and ICT. The sensor data measured in real time is displayed to the user in real time through the monitor and stored in the database. In addition, by using the stored data, it is possible to inform the registered administrator in real time of the dangerous situation by informing the dangerous situation in case of danger, and to be able to check and control remotely. This can improve safety by making control and confirmation of the state of the inside of the reagent everywhere.

The public survey performance review conducted by the Spatial Information Quality Management Institute is conducted at the screening rate in accordance with the regulations, and the examiner directly judges the overall trend of the submitted performance based on the extracted sample. However, the evaluation of the Ministry of Land, Infrastructure and Transport, the evaluation trustee shall be specified by random extraction (Random Collection) is specified by the sample. In this study, it analyzed the details of the actual site and analyzed through securing actual performance review data. In addition, we analyzed considerations according to various field conditions and studied ways to apply the public survey performance review sampling algorithm. Therefore, detailed sampling criteria analysis by performance reviewers is necessary. A relative comparison was made feasible by comparing the data for which the real performance evaluation was performed with the outcomes of the Python automation program. This automation program is expected to be employed as a foundation program for the automated application of public survey performance evaluation sampling in the future.

Termites are important decomposers in the ecosystem. They are also economically significant structural pests. In this study, we reviewed the developments of termite control and recent research on termite management to provide information on the prevention and control of termites. In Korea, most of the damage to wooden historical buildings is caused by subterranean termites. Reticulitermes speratus kyushuensis is the main species, which is widely found throughout the country. In the early 1900s, inorganic insecticides, such as arsenic dust, were used for termite control. After the synthesis of chlorinated hydrocarbon pesticide in the 1940s, it was widely utilized and demonstrated high termite control efficacy. However, chlorinated hydrocarbon insecticides were later banned, disappearing from markets after reports emerged concerning environmental contamination and toxicity to humans. Therefore, the termite control industry sought a new termiticide; hence many pesticides were utilized for termite control. Organophosphate (1960s), carbamate (1970s), pyrethroid, and insect growth inhibitor (1980s) were newly synthesized and adopted. In the 1990s, the first commercial baits using chitin synthesis inhibitors (CSI) were developed, providing a means to eliminate an entire colony of subterranean termites around a structure. Many studies have been carried out on soil termiticides (liquid termiticides) and CSI baits to increase their efficacy, and different baits such as aboveground bait stations, fluid bait, and high-durability bait were also developed in the 2000s. In addition, the paradigm of termite control has shifted from localized treatments using soil termiticides to area-wide pest management using CSI baits to create termite-free zones and protect buildings over time. Termite infestations in wooden historical buildings in Korea have been reported since 1980, and considerable attention was drawn in the 1990s when several UNESCO world heritages such as the Jongmyo Shrine and the Janggyeong Panjeon Depositories of Haeinsa Temple were infested by subterranean termites. Since then, a survey of termite infestation in wooden architectural heritage has been conducted, and the National Research Institute of Cultural Heritage and Heritage Care Program regularly monitors those properties. Finally, we suggest termite management using primarily CSI baits, selective application of various soil treatments applied to the object, foundation soil treatment, research and development of durable termite baits, application of area-wide programs for wooden-building complexes, application of integrated termite management (ITM), and regular education for owners and managers to prevent and reduce termite damage.
