  • The purpose of this study was to investigate the practices for management manual development of Good Restaurants in order to apply Green Safety Management technology. A total of 128 restaurants in Seoul according to restaurant size and style were analyzed by SPSS (window ver. 12.0). Exactly 38.3% of those surveyed purchased manicured vegetables and seafood that generates less garbage; Korean restaurants displayed the lowest frequency of purchasing preprocessed foodstuff, and Japanese restaurants had the most refrigerators and thermometers and kept the refrigeration temperature the lowest. Exactly 56.5% of the restaurants sold large and small amounts of main menu separately; Chinese restaurants displayed the highest rate while Western restaurants displayed the lowest. Furthermore, only 7.3% of the restaurants were willing to sell either large or small amounts of the same menu item. Japanese style menu had the most number of side dishes (6.1) while Western style menu had the lowest (1.8). Most of the restaurants were equipped with containers for leftovers (87.4%), but the rate of customers who took out leftovers significantly differed depending on the style of restaurant (p<0.05).

  • Nature-based Solutions (NbS) are defined as practical and technical approaches to restoring functioning ecosystems and biodiversity as a means to address socio-environmental challenges and provide human-nature co-benefits. This study reviews NbS-related literature to identify its key characteristics, techniques, and challenges for its application in climate-adaptive water management. The review finds that NbS has been commonly used as an umbrella term incorporating a wide range of existing ecosystem-based approaches such as low-impact development (LID), best management practices (BMP), forest landscape restoration (FLR), and blue-green infrastructure (BGI), rather than being a uniquely-situated practice. Its technical form and operation can vary significantly depending on the spatial scale (small versus large), objective (mitigation, adaptation, naturalization), and problem (water supply, quality, flooding). Commonly cited techniques include green spaces, permeable surfaces, wetlands, infiltration ponds, and riparian buffers in urban sites, while afforestation, floodplain restoration, and reed beds appear common in non- and less-urban settings. There is a greater lack of operational clarity for large-scale NbS than for small-scale NbS in urban areas. NbS can be a powerful tool that enables an integrated and coordinated action embracing not only water management, but also microclimate moderation, ecosystem conservation, and emissions reduction. This study points out the importance of developing decision-making guidelines that can inform practitioners of the selection, operation, and evaluation of NbS for specific sites. The absence of this framework is one of the obstacles to mainstreaming NbS for water management. More case studies are needed for empirical assessment of NbS.

  • This study investigated the effects of various planting models on the joint cultivation of eggplant (Solanum melongena) and marigold (Tagetes erecta)to enhance sustainable rooftop urban farming. Rooftop agriculture is increasingly valued to boost the food supply and benefit the environment. Integrating such practices into urban planning is viewed as a way to sustainably manage resources and improve the food-energy-water cycle in cities. The experiment was conducted on a rooftop in Chungju, South Korea from May to August. Four different planting setups were used: central eggplant with peripheral marigold (SET), eggplant with a protective net (SIC), central marigold with peripheral eggplant (TES), and control with only eggplant (CON S). These models tested the effects of companion planting versus monoculture using a lightweight soil mix ideal for rooftops made from cocopeat and perlite and enriched with organic fertilizer. Measurements focused on soil conditions and plant health and assessed soil temperature, moisture, conductivity, plant height, width, and leaf size. The results indicated that the SET modelyielded the best growth. This setup benefited from marigold pest control properties and its ability to improve soil conditions by enhancing moisture and nutrient levels and aiding eggplant growth. These findings underscore the potential of mixed planting on rooftops and suggest that such approaches can be effectively incorporated into urban agriculture to boost yield and environmental sustainability. This study supports the idea that diverse planting methods can significantly affect plant growth and promote urban greening and food security.

  • These studies were conducted to investigate the changes of starch, sugar and nicotine content in relation to maturity and cultural conditions and correlation between growth characteristics and chemical components in order to improve the leaf quality. The results were summarized as follows; 1. Nicotine content, total nitrogen content and the ratio of total nitrogen to nicotine of the green leaf were increased with heavier fertilizer, wider planting space and lower topping, whereas starch, total sugar and the ratio of sugar to nicotine were decreased. 2. Starch content, sugar content and the ratio of total sugar to nicotine(T-S/Nic) in the cured leaf were decreased with milder planting space, less application of MH and delaying harvesting date. 3. It was estimated that 58.1% of starch of the harvested leaf was converted into sugar of the cured leaf, and also they were significantly correlated each other.

  • This study aimed to identify children's emotional variables (anxiety and emotional expressiveness) and parenting variables supporting emotional development (affection and concern for, respect, and trust of children) which influence somatic symptoms. Subjects were 311 6th grade children. Instruments were the Korean version of the State-Trait Anxiety for Children (Spielberger, 1973), Children's Somatization Inventory (Walker & Green, 1991), Emotional Expressiveness Questionnaire (King & Emmons, 1990), and the Parenting Behavior Test by the researcher. Analysis by t-test showed that children's anxiety influenced somatization. The children who perceived that both parents respect their thoughts, feelings and choices and that their fathers trust their behaviors and abilities showed low somatic symptoms. Supporting children's emotional development through good parenting practices was discussed.

  • The design and construction of supertall buildings has grown dramatically in recent years. This area of practice has traditionally fallen within the purview of a very small group of architects and engineers, but this is rapidly changing, as unprecedented growth and densification has spread to markets not traditionally known for high rise construction. The design community has been increasingly committed to the adoption of green and sustainable design, and the integration of smarter, cleaner technologies across the building spectrum. This paper examines current supertall design trends, and suggests that recently completed and planned projects are trending towards more sustainable solutions, and that a unique set of best practices are emerging specific to Supertalls.

  • Vancomycin-resistant Enterococci (VRE) are a leading cause of a nosocomial infection. While seven glycopeptide resistance genotypes have been found in Enterococci, vanA and vanB are the most common resistance genotypes. Aims of this study were to detect antibiotic susceptibilities of 23 Enterococcus spp, which broke out in a university hospital by the disk diffusion test, to investigate specific genes of vanA and vanB by conventional and real-time PCR. PCR for vanA and vanB was performed on 23 Enterococci, all 23 were positive for vanA type. This study reports the validation of a simple and rapid VRE detection method that can be easily incorporated into the daily routine of a clinical laboratory. Early detection of VRE strains, including those with susceptibility to Vancomycin, is of paramount clinical importance, as it allows a rapid initiation of strict infection control practices as well as a therapeutic guidance for a confirmed infection. The real-time PCR method is a rapid technique to detect vanA in Enterococci. It is simple and reliable for the rapid characterization of VRE.

  • The purpose of science education is scientific literacy, which is extended in its meaning in the $21^{st}$ century. Students must be equipped with the skills necessary to solve problems from the community beyond obtaining the knowledge from curiosity, which is called 'computational thinking'. In this paper, the authors tried to define computational thinking in science education from the view of scientific literacy in the $21^{st}$ century; (1) computational thinking is an explicit skill shown in the two steps of abstracting the problems and automating solutions, (2) computational thinking consists of concrete components and practices which are observable and measurable, (3) computational thinking is a catalyst for STEAM (Science, Technology, Engineering, Arts, and Mathematics) education, and (4) computational thinking is a cognitive process to be learned. More implication about the necessity of including computational thinking and its emphasis in implementing in science teaching and learning for the envisioned scientific literacy is added.

  • This paper articulates the STI strategy development principles and methodologies that have been elaborated through iterative processes of STI strategy development cases for the past ten years. The consultation cases include poverty traps in Nepal and Laos, African health challenges in Nigeria and Tanzania, and ASEAN global challenges in Indonesian Water, Vietnamese Green Energy, and Filipino Food, in partnership with some multilateral agencies.The iterative elaboration process has continued with consultation activities on Thailand and on Cambodia, Laos and Myanmar in planning partnership with Thailand. The principles were originally conceptualized from the benchmarking process of the Korean STI development experience. They were further incorporated as methodologies with which relevant planning bodies are guided to address individual and regional challenges through science, technology and innovation strategies. The methodologies are strong in providing plausible holistic perspective scenarios by which various stakeholders can be engaged in the planning and implementation process. But it is heuristic in nature and can be learned only through on-the-job training process. This is the structural limitation for scaling up.
