The arcades have been introduced for improving the environment of conventional markets but thermal discomfort could be occurred according to the characteristics of arcades. The purpose of this study was to compare with arcades of two traditional markets on indoor environment and find design elements that cause for built environment problems. To find the design elements which influence on the environment of the arcade, the wind tunnel tests in the arcades were conducted. The ventilation performance of the arcade was greatly influenced by the volume of arcade and the ventilation opening.

This study was aimed to analyze the effects that components of schooling building have on cooling and heating load. We made Mun-Hyun-Kwan an object of this research, practiced simple calculation and computer simulation. The simple calculation showed that installing of pair glass and heat insulater has energy saving effect of 33.8%, Double Glazing and heat insulater has 45.4%. Computer Simulation showed that installing of Double Glazing has heating load saving effecf of 27.6%, cooling load of 9.2%.

This paper aims for evaluating the wind-driven ventilation in basement parking lots of apartment. Wind tunnel tests coupled with tracer gas method were conducted, and classified by wind directions and opening types. The test results showed that, as for wind-driven ventilation, stack type openings were more successful than scuttle vent. Additionally, the rates of air amount change by wind directions for base type(no openings) were presented in the order of W > E > SW/NE > SE/NE > S/N. Finally, according to Weibull distribution in Seoul, yearly averaged wind-driven ventilation rate was calculated.

The openings for ventilation are very important design factor to make the comfortable and healthy arcade. The purpose of this study is to analyze airflow rate using tracer gas method in the arcade. To measure the airflow rate, we measured the concentration of the tracer with a VOCs analyzer and used the constant injection method. There are three opening ratios of 100%, 50% and 0%, respectively. Except for the opening ratio of 0%, the conventional market model has enough air flow rate. When the ventilating opening in 0%, it would be uncomfortable and unhealthy in the arcade even though there is low airflow rate in the openings between the buildings.

This study is to analyze the performance of a radiation-panel cooling system by means of CFD. In the first step of this study, the indoor thermal environment of the office space, which is air-conditioned by radiation-panel cooling system, is analyzed by field measurement and CFD (coupled simulation of convection and radiation). With comparing the both results, the validity of the CFD method is examined from the practical point of view. In the next step, the thermal environment of the model office space, which is cooled by tree types of HVAC system (radiation-panel cooling system, all-air cooling system, and hybrid air-cooling system of radiation-panel and natural ventilation), is analyzed by CFD. By installing a human model in the room model, the characteristics of heat transfer from human are also analyzed. In the case of the radiation-panel cooling system, operative temperature and MRT(Mean Radiation Temperature) of the human model become lower than those in all-air cooling system. The radiation-panel cooling system is concluded as very energy-efficient in this study.

The main purpose of this study is to enhance the understanding of satisfaction and behavior in a residence hall. Furthermore, the study examines how consistent or different results of the present study are, compared to the previous one, done with another residence hall, in the same campus. The analysis was carried out by means of observation and questionnaire research designed for a residence hall at Hongik University, Chochiwon. A 5-story residence hall, recently constructed with the modified layout based on the result of the previous study, was chosen for the study. Among others, the results of the both studies consistently showed that lack of space in the residence unit was the most dissatisfied factor, in spite of the fact that a great majority of the students studied and spent leisure time in the unit. In addition, the present study indicated that the overall unit dimension must be increased due to the extended size of the table to carry personal computers that most students have in their residence units.

To activate traditional markets under deterioration, Korean government have carried out the environmental renewal policy of the traditional market including the induction of arcades. The purpose of this study was to provide the basic information on the design standard of arcade in the traditional markets by 1) analyzing the present condition and the environmental renewal policy of traditional market and grasping the tendency of renewal policy, 2) classifying the street markets into 5 types and finding the street market type that often applied the arcade and 3) selecting two traditional markets that had arcades and investigating the actual condition by the questionnaire to merchants. As a result of the study, the arcades will be introduced for improving the environment of 11 traditional markets that have the streets(width 6m·12m) and many 2-story buildings. And the merchants thought fire safety problem and thermal environment to be important.

Early repolarization is a common electrocardiographic (ECG) feature found in young adults, men and athletes, and has been considered to be a benign feature for the last several decades. But recent studies suggest that early repolarization may be related to idiopathic ventricular fibrillation and sudden cardiac death. We report a young man, 35 years old, who had life threatening ventricular fibrillation and sudden cardiac arrest. He was evaluated for cardiac causes of ventricular fibrillation. There was no explanation other than that his ECG showed an early repolarization pattern so we treated him with implantable cardioverter defibrillator. Thus, we suggest that early repolarization may be related with life threatening ventricular arrhythmia.

The arcades have been introduced for improving the environment of conventional markets, but thermal discomfort, poor IAQ and fire safety problems were occurred in same arcades because designers do not have proper design guideline for the arcades. The purpose of this study was to compare with two arcades on indoor environment and find design elements that cause for built environment problems. To find the design elements which influence on the environment of the arcade, the field measurements in the arcades were conducted, including temperature, humidity, air velocity, CO/CO2, etc. The indoor environment of the arcade was greatly influenced by the volume of arcade and the ventilation opening.
