With the building is higher and higher, the stack effect is more and more remarkable. The stack effect accompanies many problems in high-rise building such as draft, troublesome in door opening, uncomfortable noise, contaminants dispersion, etc. In this study, the air movement and accompanied contaminants dispersion by stack effect in high-rise building, and diluting the contaminants concentration were analyzed. The analysis was performed for high-rise residential building in Seoul, Korea and the network simulation method was used. The results show that the indoor contaminants concentration and air movement caused by stack effect have interdependent relationship.

Reading room in the university is one of necessary facilities that university student must use. It is, therefore, very important to make reading room comfortable acoustically not only to minimize the annoyance to the users but also to provide efficiency in studying. Present study aims to investigate the current situation of reading room in terms of acoustics and moreover to find out the relationship between the indoor noise and users' satisfaction through questionnaire survey. As a result, the indoor noise level is quite higher than the 1st grade, 35 dB(A), that the Ministry of land, transport and maritime affairs suggests as certificate regulation for environment friendly building and there were lots of noise sources that can provoke users in studying or concentrating. Questionnaire survey illustrates that the sound when opening and closing door, and airborne sound from outdoor transmitted through window are most annoying, which affected users' dissatisfaction.

The scale and the extent of a aging of population of a rural are more serious than those of a urban in China. However, the welfare policy and the service for the aged in the rural are inferior. China established the different systems of social welfare policy for the city and the rural and has administered it since the china was established. Owing to an open-door policy(opening of a reform) the gap between the two got more deeply distinguished. Accordingly. the striking difference is shown in a living environment and a quality of life of the cities and the rural. I made clear the difference of services for the aged in the rural and the urban examining daily lives, medical industry, recreation systems and so on and analyzing their sources. In addition, I proposed the ways to establish synthetic social welfare policy of the urban and the rural.

Chungju city with beautiful natural environments and various cultural resources recently meets the new economic revival caused by opening of Jungbu Naeruk express way and invitation of the enterprise city. Now, the out door lightings come to the major issues to improve Chungju night image and to exploit new scenic spots. this study aims to develop the lighting plan for the jung-won bridge as a representative scenic spot in Chungju city. For the study, the field surveys and computer simulations were performed. As results, the lighting concepts such as entrance and apple images and alternative lighting plans were suggested.

In conclusion, the seemingly fuzzy and disorganized data of biology with thousands of different layers ranging from molecule to the Internet have refused so far to be mapped precisely and predicted successfully by mathematicians, physicists or computer scientists. Genomics and bioinformatics are the fields that process such complex data. The insights on the nature of biological entities as complex interaction networks are opening a door toward a generalization of the representation of biological entities. The main challenge of genomics and bioinformatics now lies in 1) how to data mine the networks of the domains of bioinformatics, namely, the literature, metabolic pathways, and proteome and structures, in terms of interaction; and 2) how to generalize the networks in order to integrate the information into computable genomic data for computers regardless of the levels of layer. Once bioinformatists succeed to find a general principle on the way components interact each other to form any organic interaction network at genomic scale, true simulation and prediction of life in silico will be possible.

A study to evaluate the fire extinguishing performance of the water mist system inside simulated machinery spaces according to IMO MSC/Circ.668 was performed. Fire tests were conducted inside a compartment having a area 100$m^2$(10m${\times}$10m) with a ceiling height of 10m and door opening of 2m${\times}$2m in size. Test fuels were used heptane, diesel, wood crib and mineral oil. Water mist nozzles were installed downward at ceiling and horizontally at bilge area. All fires in the test were extinguished within 15minutes of system activation and there was no reignition or fire spread.

A PSD system has a lot of characteristic for safety. Trust of performance test is very important. But PSD performance test has an effect on trust by proficiency of test staff because it is difficult to automate. In that specially the effort test, manual opening and shutting test and abrasion measurement, test staff is demanded for proficiency. Therefore the paper repeated measurement in same condition and studied proficient factor of examiner according to increased measurement counter. As a result, measurement uncertainty has improved.

The focus of this study is on the diffusion and aspects of Yoenji make-up in China. The diffusion of Yoenji make-up into China was achieved by Zhuang-Kun's departure for the West of China, after Emperor Moo of Han Dynasty defeated the Huns (B.C. 121). The Yoenji make-up is basically used as a unique sign and from the result of excessive development from the facial beauty point in accordance with luxurious Court culture and opening door of culture. It can diversely express kinds, names, ways, types and patterns, places and bodily parts, the colors of materials for use, and time zones of a make-up.

In this paper, an augmented refrigerator is proposed that presents information to increase the awareness of electric power consumption of a household fridge. The key idea is to reflect wasteful behavior on the feedback to a user, rather than mere amount of consumption or duration of opening a door of a fridge.
