The purpose of this study is to identify the supply status and planning trend of North Korean housing through analysis on the North Korean architecture specialized media data. The flat composition is changing and the living room is becoming the center of the houses. Also, in the urban areas, the standard apartment type is four apartments in a row and the plan form is getting diversified into circle type, Y type, and irregular type. On the other hand, in the rural areas, two houses in a row and single house are typical and the change in planning scale and space structure are not substantial. Since the 2000s, design changes have been made to emphasize the third dimensional structure of buildings such as the elliptical houses and L-shaped houses. Furthermore, 8~10 households are located on one floor which leads to the tendency of the building enlargement. In terms of house size, a square concept was introduced to replace the initial 2~3 room concept and the basic module of the room planning the 3 room house based on $3m{\times}3m$. However, there seems to be no standard house size, and the house size may differ depending on the social classandregion. In the early 1980s, when there was focus on the apartment complex construction, the high-rise apartment buildings of 30~40 floors was planned. However, during the Pyongyang redevelopment project, apartments of more or less than 10 floors were built and row-houses of more or less than 4 floors were built. In terms of the complex scale, a lot of small complexes of around 300 households are emerging after 2010. The construction projects are mainly limited to specific regions such as Pyongyang and Samjiyeon, and also limited to specific classes such as the workers and soldiers initially and the scientists lately. In addition, living boundary composition and ancillary facilities for sufficient green area ratio securement and the people of North Korea are maintained consistently. In recent years, the specialized floor planning such as solar house and the house for the disabled people, framework houses for redevelopment business, and multi-storied house construction technology are also emerging.

This paper is to compare the absorption coefficient with normal incidence waves and it with diffuse incidence waves of glass wool which the most used absorption material and multi layer fiber. The absorption coefficient with normal incidence waves is calculated by surface impedance that measured by using an acoustic tube. Based on this data, the absorption. coefficient with diffuse incidence waves is predicted and is compared with measured the absorption coefficient in reverberation room.

In this study, the room acoustics of a hall in Kimhae Performing Arts Center is discussed. The hall is designed as a multi-purpose hall. The reverberation time of the hall is varied by absorptive/reflective surfaces. A design method using both objective and subjective evaluations is investigated. As a result, the geometrical shape and the interior materials are determined.

In the indirect optical bio-telemetry, high frequency response and low minimum detectable optical power can be achieved by using photodiode with small light receiving area which minimizes junction capacitance. But, on the other hand, S/N ratio becomes low because the optical signal current is small. To solve such a problem, we attach plato-convex lens in front of photo diode, The results of comput- er simulation and experiments suggest promotion of light receiving efficiency and possibility of multi- telemetry system through directivity of convex lens in one room.

Recently, many studies are performed according to increased interests about factory or room acoustics. In this study, the inside and environmental noise conditions of Diesel-locomotive load test building were investigated by multi-channel noise measurement system. In addition to this, the mitigation effects of environmental noise from this test building were analyzed using commercial software.

This study indicates bed-transfer as the significant behavior of a ward and points out architecture that cannot meet the patient's need. It is examined that inpatient's behavior depends on visibility, psychological security, privacy & communication, control, support and this study applies them to analyze the selected cases. This study also emphasizes the supportive role of hospital architecture so that the function of a ward as a healing environment may be maintained.

This study was attempted to find out the actual conditions about drug education among the elementary school teachers. Subjects consisted of nurse-teachers 175, class-room teachers 240 and athletics teachers 53 at the elementary schools in Pusan city. The data collecting period was December 23th through December 28th, 2002 and the collected data were analyzed by SPSSWIN 10.0 program using frequency, percentage, mean, standard deviation and $x^2$-test. The results of this study were as follows: 1. The importance of the drug education in special curriculum has been agreed with 96.0% of nurse-teachers, 90.4% of classroom teachers and 92.4% of athletics teachers. 2. For the drug education, nurse-teachers used to get information through the professional knowledge books(61.1%), and internet (33.1%), on the other hand class-room teachers(80.0%) and athletics teachers (48.9%) used to get information from various media. 3. Until now, the drug education has been performed by 80.6% of nurse-teachers, 34.2% of class-room teachers and 41.5% of athletics teachers. After drug education, the results of self-evaluation showed that 73.8% of nurse-teachers and 51.9% of athletics teachers were satisfied with it, but 69.5% of class-room teachers were not. In terms of the education methodology, most nurse-teachers(85.8%) usually used both verbal lecture and multi-media materials for teaching, but class-room teachers(97.8%) and athletics teachers(81.8%) just gave the verbal lecture. 4. About practical difficulties of drug education, the biggest problem was the absence of no systematic curriculum for nurse-teachers(22.9%), the insufficient expert knowledge for class-room teachers (26.3%) and a lack of education materials for athletics teachers(37.7%). The subjects were responded that the well-qualified personnel in charge of drug education in elementary school were nurse-teachers (52.0%) or nurse-teachers and class-room teachers.

Drawing process of the high carbon steel wire with high speed is usually performed at room temperature using multi pass. Tn the multi pass drawing, temperature rise affects the mechanical properties of the final product. The excessive temperature rise during the deformation promotes the occurrence of delamination, and deteriorates the torsion property and durability of wire. This paper investigates the occurrence of delamination in the wire through the torsion test and the evaluation of wire temperature. The excessive wire temperature ieads to the occurrence of delamination. Based on the calculation of the wire temperature, a new pass schedule, that can prevent the delamination due to the excessive wire temperature rise, is designed through the isothermal pass schedule.

In this paper, the control of the temperature for the vehicle air conditioner is implemented with the fuzzy controller using a micro controller. The linguistic control rules of the fuzzy controller are separated into two out variables(multi input multi output ; MIMO) : one is those for the blower motor, and the other is those for air mix door. The error in fuzzy controller, the input variable is defined as difference between the reference temperature and the actual temperature in the cabin room. The fuzzy control rules are established from the human operator experience, and based engineering knowledge about the process. The method of the center of gravity is utilized for the defuzzification.

The purpose of this study is to get preeminent data from comparative analysis of multi-family housing unit plans between Korea and China nowadays. Even though Korea and China belong to common cultured band in Asia, there are many different Housing aspects and unit plans. Through this study we want to grasp the characteristics of both nation's apartment unit plans and to contribute for advance into the China apartment market. Analysis target is constructing and lotting out apartment at South Korea and China in 2004, and the space syntax model is used as an analysis tool. First, analyze kind, number and special quality of each room by use area, and second, analyze area and scale of the rooms. Through the integration analysis we know the grade of rank and centrality of each rooms, and search difference of South Korean and Chinese apartment.
