In the summer season, natural ventilation is commonly used to reduce the inside air temperature of greenhouse when it rises above the optimal level. The greenhouse shape, vent design, and position play a critical role in the effectiveness of natural ventilation. In this study, computational fluid dynamics (CFD) was employed to investigate the effect of different roof vent designs along with side vents on the buoyancy-driven natural ventilation. The boussinesq hypothesis was used to simulate the buoyancy effect to the whole computational domain. RNG K-epsilon turbulence model was utilized, and a discrete originates (DO) radiation model was used with solar ray tracing to simulate the effect of solar radiation. The CFD model was validated using the experimentally obtained greenhouse internal temperature, and the experimental and computed results agreed well. Furthermore, this model was adopted to compare the internal greenhouse air temperature and ventilation rate for seven different roof vent designs. The results revealed that the inside-to-outside air temperature differences of the greenhouse varied from 3.2 to $9.6^{\circ}C$ depending on the different studied roof vent types. Moreover, the ventilation rate was within the range from 0.33 to $0.49min^{-1}$. Our findings show that the conical type roof ventilation has minimum inside-to-outside air temperature difference of $3.2^{\circ}C$ and a maximum ventilation rate of $0.49min^{-1}$.

Pavilion is an important landscape installation in the traditional landscaping and a representative facility that organizes space. To interpret and succeed the traditional landscape space, researches on the shape and structure of the traditional pavilion are also needed. However, researches on the style and structure of the traditional pavilion are difficult to be found. Accordingly this study aimed to identify the structural characteristics of roof part that occupied the largest portion in determining the shape of pavilion. Our research findings are as follows. As a result of analyzing 15 traditional Single-room square pavilions whose structure could be identified, it was found that the main building elements that distinguished the type of roof part in the Single-room square were crossbeam, ridge pole, and baluster. Depending on the presence of roofing members, pavilion was classified into five types: crossbeam, crossbeam+ridge pole, crossbeam+baluster, ridge pole, and baluster. In addition, as a result of analyzing the load and joint that worked on crossbeam based on the shape classification of roof part, it was found that in the traditional Single-room square pavilion, crossbeam was designed to play a balancing role between pillar and load. This study is significant in that it attempted to make a close interpretation of the shape of roof part in the pavilion and the role and function of building elements in terms of size, ratio, and load.

With the development of media, modern times are actively exchanging cultures and information around the world. Therefore, product development using traditional material, which are Korean cultural heritages, can be said to be another medium that can promote our unique culture to the world. Therefore, this study attempted to develop a product suitable for the modern lifestyle that combines tradition and modernity by investigating and analyzing Korean roof tiles and applying the formative elements identified as a result of the study. Among the types of roof tiles, a Sumaksai, which is located on the front of the roof and stands out for decoration, was selected as the subject of the study, and it was developed by combining it with lighting and plates as an item for modern people seeking a life full of personality. In product development, we tried to express the traditional style as it is by making the most of the elements of the Sumaksai, and the lotus pattern, which was most commonly used in each era when roof tiles were made, was simplified and applied to the product. As the products developed in this way are used in our daily lives, we hope that users' interest in ours will increase, and that the development of various products through research on traditional material can be activated as a way to spread our culture around the world.

This study is to derive the types of displacement and damage that occur in wooden architecture cultural assets. Although the wooden architectural cultural assets are being repaired through continuous maintenance, secondary problems frequently occur. This is because the root cause of the problem has yet to be solved. The types of displacement and damage that occur in the wooden architecture cultural asset are classified into three parts: the foundation section, the gagu section, and the roof section. In turn, the three main factors that lead to displacement and damages are the structures' load impact, the durability deterioration, and the imbalance. Load impact is a phenomenon in which the member is subjected to a load that causes deformation or cracks. Durability decline is a natural phenomenon that reduces the performance of lumber as a result of check shake, termite damage, and decay. The imbalance is a condition in which the lumber is twisted and the force balance is lost, due to either drying shrinkage or displacement of the gagu section.
