It is necessary to evaluate HMI inaspects of human factors in the design stage of MMIS(man machine interface system) and feedback the result of evaluation because operators performance is mainly influenced by the HMI. Therefore, the MMIS design should be reflected the operators psychological, behavioral and physiological characteristics in the interaction with human machine interface(HMI) in order to improve the safety and availability of the MMIS of a nuclear power plant(NPP) by reduction of human error. The development of human factors experimental evaluation techniques and integrated test facility(ITF) for the human factors evaluation become an important research field to resolve hi,am factors issues on the design of an advanced control room(ACR). We developed am ITF, which is aimed to experiment with the design of the ACR and the human machine interaction as it relates to the control of NPP. This paper presents the development of an ITF that consists of three rooms such as main test room(MTR), supporting test room(STR) and experiment control room(ECR). And, the ITF has a various facilities such as a human machine simulator(HMS), experimental measurement systems and data analysis and experiment evaluation supporting system(DAEXESS). The HMS consists of full-scope simulation model of Korean standard NPP and advanced HMI based on visual display nits (VDUS) such as touch color CRT, large scale display panel(LSDP), flat panel display unit and so on.

It is known that natural awakening of us in the morning is due to stimulation of the reticular activation system through biological clock in the suprachiasmatic nucleus of hypothalamus by the morning sunlight. If we sleep at dark rooms without windows and so without morning sunlight, thus, it is not easy fur us to get up refreshingly in the morning. In this paper, we propose an automatic sunrise household lighting system that helps us fer getting up cheerfully in the morning even if we sleep in dark rooms without morning sunlight. The proposed lighting system is an embedded system that turns automatically on the electric lamp and makes it brighter and brighter coincidently with the actual sunrise. The proposed system is composed of a PIC microcontroller with flash memory, a real-time clock IC, a D/A converter, an amplifier, a dimmer unit, a light bulb, a display panel and a keyboard. The validity of the proposed intelligent lighting system is demonstrated via a prototype production and experimentation.

We investigated the importance and efficiency of active and passive exploration on the recognition of objects in a variety of virtual environments (VEs). In this study, 54 participants (19 males and 35 females) were randomly allocated into one of two navigation conditions (active and passive navigation). The 3D visual display was presented through HMD and participants used joysticks to navigate VEs. The VEs consisted of exploring four rooms (library, office, lounge, and conference room), each of which had 15 objects. 'Active navigation' was performed by allowing participants to self-pace and control their own navigation within a predetermined time limitation for each room. 'Passive navigation' was conducted by forced navigation of the four rooms in random order. Total navigation duration and objects for both navigations were identical. After navigating VEs, participants were asked to recognize the objects that had been in the four rooms. Recognition for objects was measured by response time and the percentage of correct, false, hit, and miss responses. Those in the active navigation condition had a significantly higher percentage of hit responses (t (52) = 4.000 p < 0.01), and a significantly lower percentage of miss responses (t (52) = -3.763, p < 0.01) in object recognition than those in the passive condition. These results suggest that active navigation plays an important role in spatial cognition as well as providing a better explanation about the efficiency of learning in a 3D-based program.

Large scale display panel(LSDP) is a main component in the next generation main control rooms. LSDP is located at the front of VDU-based operator's workstation and plays an important role in providing operators with overall information of plant status through mimic diagram, text/digit, graph, and so on. A critical matter determined at the first stage of LSDP design is how much information is displayed, because the information density of LSDP affects operator's performance. Many human factors guidelines recommend low information density of displays to avoid degrade of operator's performance, but doesn't provide a useful limit of information density. In this paper, we considered information density as the number of plant parameters and investigated the proper number of plant parameters through a human factors experiment. The experiment with 4 subjects was carried out and response time, error, and heart rate variation as criterion measures were recorded and analyzed. As the results, it is identified that the proper number of parameters in a LSDP is about thirty.

It is said that primary territories such as homes are ercellent examples of how we useterritories to portray ourselves to others. The homes often display openly the personality and values of its occupants. At the same time, as far as childrens' privacy in the household environment is concerned, the range of privacy options generally increases from adolescence on because there is more freedom from parents' supervision at this age period. Children are subject to perpetual intrusion because they are defined as dependents. As long as they continue in this role, they are viewed as, at best, semi-autenomous. In this paper, the authors carried out amd analized some cases specifically to see thestatistical data reported previously more intensively. The results of the analysis are as following; 1) Kids who have bed-rooms of their own(exclusively) seems to be encouraged to invite their friends in more openly and freely than those who share the same bed-room. 2) Social interaction among members of family seems tn be carried cut more frequently and closely in the extended family than in the conjugal family.

The Educational Cultural Center for Students is a new mixed-cultural space which made around 1997 for students' education of humanism and talent with the 7th revision of educational course. This Educational Cultural Center for Students is different to the existing one because the subject of the culture is students who make creation and performance by themselves while the former ones were for seeing, hearing and feeling things. There are seven Educational Cultural Center for Students all over the country and will be built more in the future. Comparing to the former Educational Cultural Centers for Students, functional rooms in the Educational Cultural Centers for Students are an outdoor performance room, a large performance room, a small performance room of performance facility, a gallery of display facility, a gymnasium, a swimming pool, a fitness room, a table-tennis room of physical facility, a library and a reading room of a book facility, and a group room, a computer room, a singing room, a billiard room, an art room, a musical room, a dancing room, a manner room, a playing room, a cultural lecture room and a seminar room of a interest-activity facility. The result of analyzing the usage frequency is that a performance room has the highest frequency and a display room, a musical room, a music appreciation room and a physical room follow the frequency order. But this frequency does not fit for all area. By place and social situations, the frequency and space organization may be changed.

문화재를 보존, 보관, 전시하는 박물관의 전시실은 실내 공기에 부유하고 있는 먼지와 곰팡이로 인해 생물적 피해를 받는다. 미생물의 발생은 문화재 표면의 착색, 재질 분해, 변질 등의 손상을 야기한다. 본 연구에서는 무위사 성보박물관의 전시실, 전시진열장, 그리고 벽화 표면의 미생물 분포 상태와 온습도 분포 특성을 조사하였다. 전시실과 진열장에서 포집된 미생물을 동정한 결과, Aspergillus sp., Penicillium sp., Cladosporium sp. 등 다양한 미생물이 동정되었다. 특히 1, 3 전시실은 2 전시실에 비해 미생물의 개체 수가 많은 것을 알 수 있었다. 3개 전시실 모두 온 습도 분포도를 살펴본 결과, 대부분이 $28{\pm}4^{\circ}C$의 높은 온도 분포와 70~80% 사이의 고습도 환경에서 높은 분포율을 나타냈다. 각 전시실의 진열장을 비교한 결과, 1 전시실의 진열장이 2, 3 전시실의 진열장에 비해 높은 습도환경 분포율을 보였는데, 이는 미생물 농도 분포와 상관성이 있는 것으로 판단되었다. 이와 같은 무위사 성보박물관 전시실 및 진열장 내부의 고온, 고습 환경의 분포는 근본적으로 전시실의 밀폐도와 환경관리 등에 의해 발생되는 특성임이 확인되었다.

The purpose of this study is to investigate the basic historical characteristics and its modern trend of Torajan traditional housing architecture in Sulawesi Province, Indonesia. The Toraja culture belongs to the cosmological culture with Cosmos centric characteristics. A traditional house, being called 'tongkonan' in Toraja region, is more than just a structure, representing the symbol of family identity and tradition. The Torajan architecture is a combination of the myth and cosmos, also regional conditions. With a short description of the general conditions and spiritual values of the Toraja, this paper explains the space-composition, the stylistic characteristics, the ornamental elements, construction, and its modern trend, etc. In general, it is raised on stilts several metres high, with a dramatically boat-shaped roof. Village layout varies according to size. The houses are arranged in a row, side by side, with their front gables facing north. Each house stands opposite its own rice-barn. The houses with their oblong ground-plans, built on piles set on stones. The interior is divided into three or four rooms, having few window. The houses are embellished with carving and paintings, and the facades display engraved and painted geometric and figural designs. The most frequent motif is the buffalo head, ranging from the realistic to the highly stylized. The Torajan traditional housing have experienced radical changes during the Modern period. In spite of the popularity of new modern house-styles, the traditional architectural style is often now constructed as an icon of Toraja identity. This paper will be helpful for understanding regional diversity of the traditional housing in Southeast Asia.
