Prevention of exhaust gas back flow becomes a great interest to shipyards and shipowners in large container carriers because exhaust gas pollutes cargoes, flows back into the deck house and the engine room area through fresh air intakes and fan rooms, gives harmful damages to the crew's health and also gives thermal damages to electric equipments on the navigation deck. The phenomena of exhaust gas back flow has been studied with the analysis of sea trial records and wind tunnel tests and the height of the exhaust gas pipe, the front area of the deck house, the inflow speed and the position of the radar mast platform has been confirmed as the principal factors of exhaust gas back flow phenomena. The simple empirical formula to estimate exhaust gas back flow phenomena and the design guidances of exhaust gas related structures on deck has been introduced. In future, parametric studies for the exhaust gas back flow factors will be carried out with the CFD analysis. The results of this study will be the guide for development of the prevention method of exhaust gas back flow phenomena for large container carriers.

This paper aims to clarify the spatial form and functional transition of Korean traditional shop house in Maehwa marketplace, Uljin. The general form of Korean traditional shop house of Maehwa marketplace was the timbered house of the tin roof built in the 1960s. As the scale of a building being comparatively small-scale, building area is $60m^2$ and the yard was mainly made behind the building. When the spatial form of Korean traditional shop house is considered, the composition of 4 by 2 is most. And in the front of a building, the shop is located, and when the back of a building prepares a residence, integration of a sales function and a habitation function is seen. The shop of Korean traditional shop house is converted into living space by change of the function, and the position is the middle of a front of building. This is considered as what inherited the Korean lifestyle. And the last, Although it is not different from the appearance of the shop house of other areas, since there are few grades of the change in comparison, the extension situation of Korean traditional shop house is recognized as an example important for future research.

Pungsu acts as a strong guideline for selecting a location of the village having a certain geographical condition. The attitude of choosing an auspicious site regarding the shape of mountains and water stream, is widely accepted by the intelligent class of Josen period. Therefore, the theory is one of the main factor influenced on the traditional village and house in Korea. Regarding the fact that a real effect of pungsu on the formation of traditional village and house, Study with a view of Pungsu theory could be a good method for deeply understanding the traditional architecture in Korea. In this context, the study analyzes the site and space lay out of an upper class house of vice minister Lee(Lee, Jung Ryul, 1868~1950) in Oeam historic village with Pungsu theory. The house is composed of Anchae(house for the women) and Sanrangchae(house for the men and receiving guests) and Hangrangchae(servants' quarters). Through the study, It finds out that the house is carefully selected and planned considering surrounding physical environment so called Jusan(back hill), Ansan(front hill), Choengyong(blue dragon) and Beckho(white tiger) of Pungsu theory.

This paper overall and systematically investigates of basic design know-how on commonly indwelling timber framework in a folk house in Yeosu area. in other words, Setting the goal of 'investigates of common form of timber framework', and for this goal, surveyed and analyzed for folk house a lot of findable in Yeosu area. As a result, elicits for four types plural common form((1) 4 front 'kan' - a hipped roof construction - front 'toi'/3 'ryang' - no central pillar/side beam type, (2) 4 front 'kan' - a hipped roof construction - front 'toi'/3 'ryang' - one side central pillar/central side beam type, (3) 4 front 'kan' - a hipped roof construction - front/back 'toi'/2'kozu'5'ryang' - no central pillar/side beam type, (4) 4 front 'kan' - a hipped roof construction - front/back 'toi'/'2kozu'5'ryang' - one side central pillar/central side beam type). Common form is at that time, so commonly located in the head of the technician that a form that play an exemplary role in design, or it is concretely assumed for commonly aimed form. in other words, Common form is come into existence on premise for basic design data. Documentation of folk house design know-how is done through this, and the base design and specification of korean private house is written in the contents divided into by areas.

House ownership is considered as one of the important pre-conditions for marriage in China. Given that gender imbalance is a prominent issue in the country, competition for marriage partners might motivate males to look for a house and probably bigger and more expensive house. This is believed to have caused house price hikes in recent years. This study aims to investigate the impact of gender imbalance on house prices using data from 30 provinces in China for the 2000-2017 period. The results based on the generalized method of moments (GMM) estimations show that house price is strongly influenced by gender imbalance. However, there is no evidence to support differential effects across eastern and mid-western regions. One potential reason is that pre-marriage house ownership has become a common culture for the whole community and therefore it does not vary significantly across regions. There are several important policy implications. Firstly, the issues should be addressed by the policymakers at national level and not regional level. Secondly, the government should intervene to bring back gender ratio to its normal level. Finally, the government should limit the number of houses people can buy and increase the supply of houses in the market.

Purpose: The research is focused on the 25th King Cheoljong's mother's parents' traditional House in Ganghwa-do, for finding out how the surrounding natural environment was considered with Pungsu, a traditional ecological architectural science in case of site selection and architectural planning by the relative of royal family of Joseon period. Method: The study is processed as follows. Human Environment of the region where the house is located, is analyzed in chapter 2. Feature of mountain expressed as dragon and four important hills of the house are analyzed in chapter 3, Highly regarded factors for site selection by the scholar of the Realist School of Confucianism such as wind environment, the front and back of the Hyunmubong and building orientation are analyzed in chapter 4. Finally Pungsu applied in architectural space is analyzed in chapter 5. Result: The house considered Pungsu to some extent, but it shows the appearance contrary to the Pungsu in a certain part in order to show authority and proud as the house of the relatives of the King. It can be seen that the degree of application of Pungsu may be different depending on the will of the building owner.

The object of this study is one of the traditional houses about Siheyuan(courtyard house) which is one of the most remarkable types of dwelling in China. The purpose of this paper is to examine and analyse the formation process of the Siheyuan. Its organizational formation process are based on historical and natural-geographical background. With the passage of time this house developed into one of the Chinese house style. The technique of Siheyuan's spatial composition goes so far back in the New Stone Age. The relics of this are the colony layout, the system of four sides, the layout type of a palace, the picture of lacquered ware, the picture of brick, the earthenware of house type, the painting of cave, the paintings of painters and others.

In Korea the population of breeding house swallow is continuously decreasing. In this regard this study was conducted to find out the overall population trend during 2001-2005. The areas of urban and rural sites were separated to estimate population. Also the sites in Yangpyung areas were chosen to compare population density between two sites during Mar-Aug, 2006. The house swallow had two breeding periods and I tried to correlated amount of days of incubation and number of eggs in the nest. After egg hatching the homing behavior also was estimated assuming lack of foods takes longer to bring foods back to the nest. This study signified that a long term study should be conducted for population change and spring arrival time due to climate change in Korea.
