Water distribution systems supply drinking water to consumers' taps. Internal corrosion of metallic pipe used in drinking water distribution systems has reduced water quality and led to increased levels of toxic heavy metals such as lead, copper and nickel. These problems have been experienced to varying degrees by water utilities in many countries. North America has successfully managed and controlled pipe corrosion and corrosive water in water distribution system based on various policies, regulations and rules. Practical and engineering guidelines for evaluation of pipe corrosion and determination of treatment options are also provided to assist drinking water supplies. In addition, the corrosion mechanism in water distribution systems, such as the complex effects of physical and chemical parameters on the corrosion pipes has been improved to accurately predict corrosion rates of metallic pipes in actual water distribution systems. This paper reviews various regulations, policy statement, and treatment produces on controlling corrosion in drinking water distribution systems in US and Canada and then offers suggestion for management of corrosive water and pipe corrosion in drinking water distribution system in Korea.

Objectives: Personal protective equipment (PPE) is an essential means for protecting workers against hazardous agents or risks that threaten their safety and health. Governmental organizations related to safety and health in the workplace regulate the PPE rules to protect workers and to minimize damage from hazardous agents. This study discussed current PPE rules overseen by the Korea Ministry of Environment and explores future perspectives on the matter. Methods: This study was based on a review of PPE regulations with which every stakeholder should comply in the workplace. Both South Korean regulations enforced by the Ministry of Employment and Labor and the Ministry of Environment and cases from other countries were reviewed. Results: Regulations related to the PPE required for handling chemical substances in the workplace are enforced by the Occupational Safety and Health Act, Enforcement Decree, Enforcement Rules, and Notification of Protective Equipment Certification under the Ministry of Employment and Labor. The Ministry of Environment also regulates the PPE standards for 97 substances requiring preparation for accidents and adjustment of work conditions, but a recent amendment (partially amended on September 30, 2022) loosened some unreasonable or excessive provisions. It requires workers simply to carry or otherwise keep PPE handy instead of wearing it for some tasks in which hazardous chemicals are not handled directly. Conclusions: It is important to regularly review provisions that need to be improved or supplemented to help all stakeholders. Considerations should be also made to build a reasonable regulatory system that can induce more mature safety management in each workplace.

Diesel engines which emit a lot of PM and NOx have been known as a main air polluter. Especially, diesel particulate matters (OPM) including black smoke are hazardous air pollutants to human health and environment. The nations retaining advanced engine technologies have reinforced emission regulations. To meet these regulations diesel engine manufacturers have developed low-emission diesel engines, aftertreatment equipments, alternative fuel technologies and so on. In this study, particle number concentrations characteristics according to particle size and engine driving conditions were analyzed when these low-emission technologies were applied. There was a tendency of increasing particle number concentrations from heavy-duty diesel engines with increasing engine rpm and load rate. In the cases of COPF (Catalytic Diesel Particulate Filter), CNG (Compressed Natural Gas) engine and ULSD (Ultra Low Sulfur Diesel) more than 99% of particle number concentration were removed.

Background: Substantial empirical research has shown conflicting results regarding the influence of organizational external factors on construction risk management, suggesting the necessity to introduce a moderator into the study. The present research confirmed whether rules and regulations matter on the relationships between organizational external factors and construction risk management. Methods: Based on discouragement and organizational control theory, this research examined the effects of organizational external factors and rules and regulations on construction risk management among 238 employees operating in construction companies in Abuja and Lagos, Nigeria. A personally administered questionnaire was used to acquire the data. The data were analyzed using partial least squares structural equation modeling. Results: A significant positive relationship between organizational external factors and construction risk management was asserted. This study also found a significant positive relationship between rules and regulations and construction risk management. As anticipated, rules and regulations were found to moderate the relationship between organizational external factors and construction risk management, with a significant positive result. Similarly, a significant interaction effect was also found between rules and regulations and organizational external factors. Implications of the research from a Nigerian point of view have also been discussed. Conclusion: Political, economy, and technology factors helped the construction companies to reduce the chance of risk occurrence during the construction activities. Rules and regulations also helped to lessen the rate of accidents involving construction workers as well as the duration of the projects. Similarly, the influence of the organizational external factors with rules and regulations on construction risk management has proven that most of the construction companies that implement the aforementioned factors have the chance to deliver their projects within the stipulated time, cost, and qualities, which can be used as a yardstick to measure a good project.

T Recently, the government has been promoting the expansion and supply of renewable energy as an alternative for achieving carbon neutrality and the nationally determined contributions by 2030. In 2020, the Ministries of Industry and Environment and the Korea Forest Service collaborated to build a nationwide onshore wind energy siting atlas considering wind resources and forestry and environmental regulations focused on central regulations. In this study, the ordinances of the local governments were analyzed to examine the effects of regional location regulations on the expansion of onshore wind power energy generation facilities, in addition to those of central regulations. A development permit standard survey of 226 urban plan ordinances of the local governments nationwide showed that presently in 2022, 52 municipalities are applying regulations on wind energy generation facilities by ordinances. This is twice more than that in 2018, when renewable energy power generation facility development was difficult. Additionally, the location regulations applied by these ordinances were organized by items and regions, and regulatory characteristics, such as the number and scope, were analyzed by regions. To analyze the spatial distribution characteristics, JeollaNamdo was selected as the case area. A spatial DB was established for regulated areas based on the regional and central regulations, and the spatial distribution characteristics and the regulatory scope were compared and analyzed.

This study initiates from the question of whether current advertising regulations are appropriate to be applied to the market. It confirms the relationship between misleading online advertisements of weight-loss food and consumer damages. This study argues that it is necessary to enforce monitoring and regulating (strengthening monitoring) for situations where misleading advertisements are exposed in the market with subsequent consumer damages. However, deregulation is needed for advertisements exposed in the name of misleading advertisements but with no consumer damages. In conclusion, the regulations of current weight loss foods are properly established $vis-{\grave{a}}-vis$ the market situation. However, misleading advertisements are prevalent for all regulated types: Type I (product quality and effect), Type II (endorsement and warranty), Type III (ways to use and safety), Type IV (comparison and superiority), and Type V (company information). Promotion targeting businesses, market monitoring and control are necessary to ensure that advertising regulations (which have existed only as an institution) can be appropriately applied. It is also confirmed that 'comparison advertising' (applicable to Type IV where consumer damages were not shown compared to other regulations) does not have an actual effect as a consumer protection regulation that should be considered in regulation revisions. Consumers also did not recognize Type III and V in the purchasing stage while consumer damages were demonstrated; consequently, this implies that consumers need to check and become attentive to these types.

In Korea, the number of recreational vehicle (RV) has been increased dramatically recent year. Now there are emission regulations for RV which include pollutants such as CO, HC, NOx, PM. However considering the trend of preferring RV, there needs more strict strategies to control emissions from this type of vehicle. For that reason, we studied emission characteristics of RV and provided basic emission data to evaluate the contribution of RV to the total air pollutant emissions and to establish RV emission management plan. A total of 21 RV were tested on the chassis dynamometer system ranging from small to large engine displacement by vehicle speed, fuel types, regulations and fuel efficiency in order to investigate the characteristics of CO, HC, NOx and PM. For the test modes, 10 different driving speed modes and CVS-75 mode were used. On the basis of this study, RV pollutants emission factors and management strategies will be proposed.
