  • The apartment buildings were hard to emission of water vapor by reduced infiltration. The purpose of this study was to investigate the generation of indoor temperature and humidity in the recent construction of small size apartment buildings. The temperature and humidity were measured in 3 apartments in Seongnam and Daejeon city. During the winter indoor temperature and relative humidity were measured ranged from 20 to $24^{\circ}C$ and 40 to 60%. Generated humidity caused by various characteristics of the residents, rather than external influences. Compare daytime (6:00 to 22:00) and nighttime (22:00 to 6:00), the temperature is low and absolute humidity is high at nighttime. Condensation is likely to occur at nighttime. Using the cumulative relative frequency and absolute humidity, small apartments design criteria (temperature, relative humidity) can be set.

  • To test if the developed ubiquitous health care devices working well and vital information could be collected and monitored systematically through internet and to test if the devices and services could be used further. Kyungwon University, KT Co., Gil Medical Center, LIG Nex1 Co., and Sujeong Health Center conducted an ubiquitous health care demonstration project in Sujeong-Gu, Sungnam, Korea from Mar. 5 to May 16. We developed and applied several medical devices to monitor health of the elderly in their houses through internet. The devices were sphygmomanometer, glucometer, body fat scale, Health Pad, and activity sensor. We distributed the devices to 20 recipients of home care and 7 diabetes patients. After received the devices and were explained how to use them, they used the devices in their houses. The vital signs of the residents were monitored through internet. A nurse monitored and consulted their vital signs in the monitoring center in Kyungwon University during the demonstration period. The consultant called them and consulted on their blood pressure, blood sugar level, and body fat after a few seconds they used the devices as well as provision of recommended contents such as diets and activities through Health Pad. To investigate cognition and satisfaction of the participants for the devices, we surveyed the participants at the end of the demonstration period. For the change in blood pressure, blood sugar level, and activities, we conducted statistical test. After the demonstration period. cognition and satisfaction for the devices and change in blood pressure, blood sugar level, and activities were evaluated. Most of the participants were acknowledged how to use the device and satisfied with the use of the devices. The internet monitoring and services are considered to be promising because most of the participants were satisfied especially because somebody was monitoring their health status. However some weaknesses such as short battery life of the activity sensor, lack of connection of consultations with hospitals, and low understanding on usage of some of the devices need to be complemented.

  • This paper proposes a collision prevention system for an agricultural unmanned helicopter. The collision prevention system consists of an obstacle detection system, a mapping algorithm, and a collision avoidance algorithm. The obstacle detection system based on a LiDAR sensor is implemented in the unmanned helicopter and acquires distance information of obstacles in real-time. Then, an obstacle mapping is carried out by combining the distance to the obstacles with attitude/location data of the unmanned helicopter. In order to prevent a collision, alert is activated to an operator based on the map when the vehicle approaches to the obstacles. Moreover, the developed collision prevention system is verified through flight test simulating a flight pattern aerial spraying.

  • The only three elements such as RQD, N -value and Es were used as a quantitative standard for the design of supporr pattern determidetion on subway line 8th in Seoul. Because the support pattern that was obtained by these elements could not he determined on the basis of the quantitative of geology and the orientations and properties of discontinuity planes, there have been some problems in determining the economic support pattern and tunnel stability. Therefore, in an attempt to determine the stable and economic support pattern with more quantitative elements, more flerrible rock mass classification with geologic conditions was performed by using RMR at 1745 sections and Q-system at 374 sections within Seongnam block on subway line 8th. Then, rusults by these two methods were compared with standard support pattern of the subway line 8th. Moreover, relationships between geology, geologic structures and topography to rock mass grades were studied. According to the rusult of this study, it is judged that the standard support pattern designed with PD-4 or PS - 4 should have been subdivided into 4~6 support patterns. Some sections where geologic structures such as faults and joints are developed tend to have rock mass grades. And they also have low rock mass grades near valley. On thr other hand, they show intermediate grades at piedmont area and the greatest ones at high mountains.

  • This study examined the preference and consumption of chungkukjang among elementary school children in Seongnam, Korea. The subjects included 583 students(male 300, female 283) who were asked to fill out a questionnaire. The collected data were analyzed using the SAS package. The results showed that 91.9% of the female students, 91.6% of children from nuclear families, and 90.7% of children with stay-at-home mothers, consumed chungkukjang. Among the children who had eaten chungkukjang previously, most had consumed it at home, and 65.5% of the students responded that chungkukjang was tasty. The data also revealed that female students, children from nuclear families, and those with stay-at-home mothers had greater preference for chungkukjang than male students, children from extended families, and those with working mothers. When asked why they dislike chungkukjang, both male and female students who had eaten it responded because 'it smells bad' and that 'it is not tasty'. However, among the students who had never eaten it, the male students replied because 'it is not tasty'(33.3%) and that 'it is not eaten at home'(27.8%), and the primary responses of the female students were 'it is not eaten at home'(65.2%) and 'it is not tasty'(21.7%). However, the subjects who had tried chungkukjang previously answered that in the future they would like to have it more frequently, as compared to the subjects who had never eaten chungkukjang. Therefore, to increase knowledge and improve perceptions of chungkukjang foods, families should give children many opportunities to try them, and in return, children will consume chungkukjang foods with pride. Furthermore, it is important that society as well as mass media, which have great influence on children, show concern and offer support in promoting chungkukjang.

  • A station is not only the public space where socially diverse classes get together and cultural interchanges occur but also the personal and emotional space where the meeting and parting occur for each individual. Thus, it is necessity to consider this dual point from the beginning of the plan to make the simple, comfortable, intuitive and friendly environment for the users in the station. Also, it should be capable of active life style of moderner according to the change of the city environment. Furthermore, as a station is not just a single-purpose space anymore but the versatile space where fulfills the user's needs for the multi-function and the desire for diversity. As the station in these days opened 24 hours for users with the modern, commercial and cultural facilities, the interior design for a station needs to be designed to be easy to use, functional and able to vitalize the environment. In order to make a desirable interior environment in a station, first of all, it is required to grasp the characteristic of the space by analyzing the phenomena of an individual or a group act in a existing space formed by the interrelation between the human and the environment. To reduce the resistance against the new environment from the user, in other words, to increase the satisfaction, it is necessity to induce the behavior of the users to the desirable way toward to the new environment. Consequently, positive methodology with recognitive approach through cognitive psychology, spatial behavior research is required.
