This research conducts a comparative analysis of the perceived importance of advancing zero energy building certification from the viewpoints of two major stakeholders - designers and building energy assessors. Both groups prioritized the importance of policy, technology, education, incentives, and promotion respectively. For designers, enhancing energy efficiency standards, developing a skilled energy workforce, and implementing an office registration system emerged as critical factors in invigorating the certification process. The findings suggest potential avenues for the government to formulate realistic strategies for boosting the certification activity.

Thermal insulation plays significant role in creating comfortable indoor environment by reduction of heat transfer between indoor and outdoor environment. Thermal insulation composition in building exterior walls is composed of various types depending on building structure type, climatic condition, economics, and so on. This study aims to quantify the energy implications of different insulation layer distribution. In this study, insulation layer distribution are categorized into three types: Inside insulation, middle insulation and outside insulation. Simulation results indicate that the cooling energy demand of building with one layer of outside insulation is the lowest. In contrast heating energy demand of building with two insulation layers, placed at inside and middle layers is the lowest. The above results imply that Insulation layer distribution of building exterior walls can significantly contribute to the improvement in the provision of cool and warm indoor environment, and energy-efficient of buildings.

The purpose of this paper is to predict the energy consumption and peak demand for electricity in a building under climate change using building energy simulation software OpenStudio based on EnergyPlus for a typical open plan office in Seoul, Korea. After the building energy simulation, annual cooling and heating energy consumption and peak demand for electricity were calculated. The result shows that building energy consumption is related to the climate change. Also, summer peak demand for electricity was the highest ever simulated with Seoul weather data in 2080. Heating energy consumption shows a tendency to decrease and cooling energy consumption is increasing every 30 years. These results vary from depending on scenarios of GHG emissions.

McCune-Albright syndrome (MAS) is a sporadic disease classically including polyostotic fibrous dysplasia, cafe -au-lait spots, sexual precocity, and other hyperfunctional endocrinopathies. Recent investigations suggest an etiological role for activating embryonic somatic missense mutations in the gene for the a subunit of Gs (Gsa), the G protein that stimulates adenylyl cyclase. DNA from bone, ovary, and blood was analyzed by using polymerase chain reaction and sequenced. A embryological somatic mutation of Gsa gene encoding substitution of a Cys for Arg at amino acid 201 from cells of dysplastic bone and ovary was observed, and the distribution of mutant gene reveals mosaic pattern. We report a case of McCune-Albright syndrome with an activating mutation at codon 201 of Gsa subunit on ovary and bone tissue that was experienced recently(J Kor Soc Endocrinol 14:779-785, 1999).
