  • The expansion of a country's ecological footprint generates resources for economic development. China's import bill and carbon footprint can be reduced by investing in green transportation and energy technologies. A sustainable environment depends on the cessation of climate change; the current study investigates nuclear energy efficiency, economic complexity, air transportation, and industrial improvement for reducing environmental footprint. Using data spanning the years 1983-2016, the dynamic autoregressive distributed lag simulation method has demonstrated the short- and long-term variability in the impact of regressors on the ecological footprint. The study findings revealed that economic complexity in China had been found to have a statistically significant impact on the country's ecological footprint. Moreover, the industrial improvement process is helpful for the ecological footprint in China. In the short term, air travel has a negative impact on the ecological footprint, but this effect diminishes over time. Additionally, energy innovation is negative and substantial both in the short and long run, thus demonstrating its positive role in reducing the ecological footprint. Policy implications can be extracted from a wide range of issues, including economic complexity, industrial improvement, air transportation, energy innovation, and ecological impact to achieve sustainable goals.

  • Background : Strategic planning is an organizationwide or systemwide, ongoing look into the future usually of 2~3 years, based on objective analysis of the current environment and trends, but it can incorporate both short-term and long-term goals. The strategic planning process includes external analysis, internal analysis, issue analysis, development of mission, vision and values, and lastly development of organizational goals and objectives. As a part of the strategic quality planning process, certain service lines, important organizationwide functions, or key processes supporting these functions can be prioritized to expedite and roll out certain strategic goals. This is called strategic quality initiatives. Methods : We organized a quality improvement team, a subgroup of 21st century vision planning corps of our medical center, and pursued QI activities for improvement of healthcare environment, particularly in the admission setting. We developed a strategic quality initiative based on the results of patient satisfaction surveys, and carried out functions of self-directed work team. Results : The strategic goal was to be the benchmark for peer group hospitals in Korea for providing cost-effective best-practice. The QI team included 3 medical doctors, 1 nurse, 1 social worker, and 1 QI consultant as well as many operational members to support services and quality initiatives met every Tuesday for 18 weeks. Outcome objectives were to improve patient satisfaction score. The issues included in the objectives were comfort, temperature, noise, cleanliness of the admission wards, quality and education of patient meals, matters regarding the admission process, and an appurtenant facility such as restaurant or convenience store. Every issue was discussed and recommendations, conclusions and opportunities were implemented. Conclusions : By developing a strategic quality initiative as a part of the strategic quality planning process, and pursuing a self-directed work team, certain sen/ice lines, important organizationwide functions, or key processes supporting these functions can be improved effectively within a short period. Strategic quality initiatives serve to support, or roll out, certain strategic goals that are relevant to performance improvement and development of specific measurable outcome objectives, and associated performance measure for each initiative. Each strategic quality initiative should include a statement of intent outcome objectives, and performance measures. We will come back with follow up of the strategic quality initiative, for improvement of healthcare environment, and results of patient satisfaction re-survey.

  • To promote environmentally responsible architectural practice, many nations have established their own green building rating system. Among other criteria, recently the indoor environmental quality section has been paid great attention due to Sick Building Syndrome, as this believed to caused by polluted indoor environment. In this context, indoor environmental quality is one of very important sections of each green building rating system and closely related to the very happiness of building users. The goal of this research is to compare and analyze the indoor environmental sections of three green building rating systems, GBCC, LEED v2.1, and BREEAM Office 2005, and find a direction for the improvement of GBCC. First, the three rating systems are analyzed in general to compare the importance of indoor environmental factors in each system. Second, the indoor environmental factors are reclassified within related sub-categories for the comparable analysis. Finally, based upon the comparable analysis, directions for the improvement of GBCC are as follows: 1. GBCC's h4r Environment Section needs to clarify its VOCs criteria based upon types of finish materials. 2. Sound Environment Section's noise control criteria needs to be revised based upon types of building usages and application method. 3. An indoor lighting related section needs to be included in GBCC, as even though light is the one of the most important factors in indoor environment, it has not been included in GBCC yet. 4. The sub-section of Confortable Indoor Environment Section related to the resting space and the universal accessibility are not in accord with the goal of green building rating system. These items need to be dealt within general building codes. 5. The rating evaluation structure and process need to be streamlined.

  • In this study, sunshine environment in an urban area is analyzed using a numerical model which considers sunshine-duration blocking by topography and buildings. The numerical model used in this study has an improvement in the algorithm detecting sunshine duration in the model domain. The main improvement in the algorithm is to detect sunshine duration using all the surfaces of any grid cell(the previous model uses the center of any grid cell). The improvement in the algorithm gives more accurate evaluation of sunshine duration at corner surfaces of buildings. Using the improvement model and geographic information system(GIS) data, sunshine environment is analysed at an building-congested area in Busan for a week in four seasons. The results show that sunshine duration can be much changed by apartment complexes, high-rise buildings, topography in the model domain.

  • An endwall boundary layer fence technique was adapted to improve the aerothermal environment of a gas turbine passage. The shape optimization of the fence was performed to maximize the improvement. The turbine passage was simulated by a $90^{\circ}$ turning duct (ReD=360,000). The main purpose of the present investigation was to focus on finding a endwall boundary layer fence with minimum total pressure loss in the passage and heat transfer coefficient on the endwall of the duct. Anothor objective function was to minimize the area on the endwall of the duct. An approximate optimization method was used for the investigation to secure the computational efficiency. Results indicated that a significant improvement in aerodynamic environment can be achieved through the application of the fence. Improvement of the thermal environment was smaller than that of the aerodynamic enviroment.
