Purpose: The purpose of this study was to investigate differences in Korean child-rearing practices between the generations of young mothers and grandmothers. Method: The participants were 98 mothers who were 20 to 39 years old and had raised one-year-old child and 103 grandmothers who were over 60 years old and had raised their children in a small city. Data were collected through self-report questionnaire based on the Korean traditional child-rearing practice from Yoo(1986). The data were analyzed using the SPSS Win 10.0 program. Results: Of 37 items in the categories of feeding and weaning, health management and taboo matters, play, and baby celebrations, the grandmothers practiced 13 items (35%) more frequently than the young mothers. However, no generation differences were found in 21 items (57%), and 3 items were practiced more frequently by the young mothers. For the young mothers, there were 15 items (41%) which were practiced over 70%, 7 items (19%) which were practiced less than 30%. Conclusion: It seems that some Korean traditional child-rearing practices were transferred to modern child-rearing practices. Therefore pediatric nurses need to pay attention to traditional child-rearing practices for the best health, growth and development of children.

Low impact development (LID) practices has become important to mitigate the damage from natural disasters in urban areas. Thereby many hydrological simulation models can simulate the hydrological impact of LID practices. However, commonly used models are not able to provide specific information to most users such as where LIDs should be placed and what kind of LID should be designed. In this study, a decision support system which can be used with the EPA's SWMM was developed for the determination of LID types and locations of LID practices, named Water Management Prioritization Module (WMPM), was applied to a urbanized university campus. Eight sub-catchments were selected as feasible candidate areas for the planning of LID practices. Pre-designated infiltration trenches and permeable pavements were applied to each selected sub-catchments, followed by peak and total runoffs comparison between before/after planning of LIDs. Moreover, TOPSIS, one of a multi-criteria decision analysis method was used in the procedure of selecting target sub-catchment areas and final prioritization of LID types and locations. As a result, sub-catchments S4 with permeable pavements and S16 with infiltration trenches has shown the most decrease in total and peak runoffs, respectively. Therefore, WMPM was found to be effective in determining the best alternative among various scenarios generated and simulated.

The purpose of this study is to suggest EAD mandatory elements to share finding aids among the Archival Institutions of Korea. Three foreign EAD best practices for case studies: the EAD Best Practice at the Library of Congress(2008), the RLG Best Practice Guidelines for Encoded Archival Description(2002), and the OAC Best Practice Guidelines for Encoded Archival Description (2005) were analyzed. In addition, the Archival Description Rules(2008) as the data content standard of Korea and the descriptive elements which are were being used at Archival Institutions of Korea were analyzed. Based upon the results of comparisons among EAD elements, in-depth interviews were performed to investigate which EAD elements should be included in finding aids as a matter of exchange format. Based upon the literature review, case studies, and interviews, the rules and EAD elements for the archival institutions in Korea were designed and suggested.

The purpose of this study is to examine the effects of human resource development policies and practices on social capital and organizational performance. To serve the purpose, we focused on the effects of communities of practice (CoP) to social capital and suggested best practices of CoP from the aspect of social capital. Specifically, we considered new kinds of social capital such as social innovation capital and social integration capital as well as traditional social capital classified into structural, relational, and cognitive capital, Where, social innovation and social integration capital represent corporate's social capacity to innovate and corporate social responsibility (CSR). And then we conducted a multiple case study on Yuhan-Kimberly, POSCO, and HIRA. From the result, we identified that CoP activities have a positive effect on social capital and organizational performance.

The Minamata Convention on Mercury entered into force on August 16, 2017. It requires Parties to the Convention to control and, where feasible, reduce mercury emissions from the listed sources. To implement the Convention, Japan amended the Air Pollution Control Law and added clauses that force operators to control their mercury emissions below emission limit values (ELVs). The ELVs have been established separately for new and existing sources, targeting the source categories listed in the Convention: coal-fired boilers, smelting and roasting processes used in the production of non-ferrous metals (lead, zinc, copper and industrial gold), waste incineration facilities and cement clinker production facilities. The factors used to establish the ELVs include the present state of mercury emissions from the targeted categories as well as the mercury content in fuels and materials, best available techniques (BATs) and best environmental practices (BEPs) to control and reduce mercury emissions and ELVs or equivalent standards to control mercury emissions in other countries. In this regard, extensive data on mercury emissions from flue gas and the mercury content of fuels and materials were collected and analyzed. The established ELVs range from $8{\mu}g/Nm^3$ for new coal-fired boilers to $400{\mu}g/Nm^3$ for existing secondary smelting processes used in the production of copper, lead and zinc. This paper illustrates the ELVs for the targeted source categories, explaining the rationales and approaches used to set the values. The amended Law is to be enforced on April 1, 2018. From future perspectives, checks of the material flow of mercury, following up on the state of compliance, review of the ELVs and of the measurement and monitoring methods have been noted as important issues.

Recently, various Best Management Practices (BMPs) have been applied at a field to reduce soil erosion. Hourly Runoff and Sediment Model for Best Management Practices (HRSM4BMP) model could be used to evaluate soil erosion reduction for various agricultural BMPs at fields. Runoff and sediment yield from source areas have to be predicted with greater accuracies to evaluate sediment reduction efficiently with BMPs. To achieve this, the best parameters related with runoff and sediment modules of the HRSM4BMP model should be identified with proper calibration processes. Although manual calibration is often utilized in calibrating runoff and sediment using the HRSM4BMP, objective calibration method would be recommended. The purpose of the study was to develop an automatic calibration tool of the HRSM4BMP model with PARASOL method. This automatic calibration tool was applied to Bangdongri, Chuncheon-si to evaluate its calibration performance. The $R^2$, NSE and RMSE value for runoff estimation were 0.92, 0.92, $0.3m^3$, and for sediment yield estimation were 0.94, 0.94, 0.0027 kg. As shown in this result, automatic calibration tool of HRSM4BMP model would be used to determine the best parameters and can be used to simulate runoff and sediment yield with acceptable accuracies.

The purpose of this study was to evaluate the reduction effect of non point source (NPS) pollution in Haean highland agricultural catchment ($62.8km^2$) for 13 BMP scenarios under RCP (Representative Concentration Pathway) 4.5 and 8.5 scenarios. Under the present climate condition, the BMP (best management practices) reduction efficiency of SS (suspended solid), T-N (total nitrogen), and T-P (total phosphorus) showed +25.7%, +4.2%, and +16.1% for VFS (vegetative filter strip), +0.1%, +15.6%, and +5.7% for FC (fertilizer control), and +6.3%, -2.9%, and +3.9% for RSM (rice straw mulching) respectively. In general, effective was the best for SS and T-P reductions, and the FC was the best for T-N reduction. The negative effect of T-N on RSM was induced by increase in infiltration and solute transport to baseflow. Under the future climate change scenarios, the SS, T-N, and T-P reduction efficiency showed the range of +1.9~+11.6%, -1.9~+0.2%, and +5.3~+11.9% respectively. The 3 BMPs (VFS, FC, and RSM) application in the future showed negative and little differences (-0.5~+1.6%) for SS and T-N reduction efficiencies while T-P reduction efficiency showed +0.3~+7.6% comparing with the baseline period. To achieve an increase in the reduction efficiency of future SS and T-N by +2~+10%, the combined application of more than two BMPs is necessary.

Sediment-laden water is problematic in aquatic ecosystem and for hydraulic structures in a watershed, and agriculture area in a watershed is one of source areas of nonpoint source (NPS), since soil surface typically exposures due to agricultural activities. Especially, severe sediment might flow into stream when agricultural area is located near stream like the Imha-dam watershed. Soil erosion is affected by precipitation, therefore there is a need to consider precipitation characteristics in soil erosion and best management practices (BMPs) simulation. The Web-based Spreadsheet Tool for the Estimation of Pollutant Load (STEPL WEB) allows estimating long-term sediment loads and the impact of best management practices to reduce sediment loads. STEPL WEB and predicted precipitation data by MIROC-ESM model was used to estimate sediment loads and its reduction by filter strip and conversion of agricultural area to forest in the future 30 years. The result indicates that approximately 70 % of agricultural area requires filter strip installation or that approximately 50 % of agricultural area needs to be converted to forest, for 41 % of sediment load reduction.

The principal objective of this study was to determine how weaning by mothers of preschool children between the ages of five and seven years influences the children's eating habits and food preferences. The results of this study will help to educate mothers about good weaning practices and facilitate the development of weaning programs by providing basic data on the subject. The results demonstrated significantly positive correlations between children's scores on eating habits and the level of vigorous weaning practices, the consistency of their practice, and the child's reaction to the foods provided (p<0.001). A positive correlation was noted between the frequency of providing solid food and the preference toward the food, with the exception of boiled rice and brightly colored vegetables. Thus, the results of this survey showed that the frequency and variety of solid foods that mothers try to actively provide their young children affect their food preferences and eating habits in general. These conclusions suggest that mothers should be educated about the significance of proper weaning so that their children can develop appropriate eating habits, and that there should be nutritional education for mothers, regarding the best weaning practices.
