The structural efficiency of tall buildings heavily depends on the lateral stiffness and resistance capacity. Among those structural systems for tall buildings, outrigger system is one of the most common and efficient systems especially for those with relatively regular floor plan. The use of outriggers in building structures can be traced back from early 50 from the concept of deep beams. With the rise of building height, deep beams become concrete walls or now in a form of at least one story high steel truss type of outriggers. Because of the widened choice in material to be adopted in outriggers, the form and even the objective of using outrigger system is also changing. In the past, outrigger systems is only used to provide additional stiffness to reduce drift and deflection. New applications for outrigger systems now move to provide additional damping to reduce wind load and acceleration, and also could be used as structural fuse to protect the building under a severe earthquake condition. Besides analysis and member design, construction issue of outrigger systems is somehow cannot be separated. Axial shortening effect between core and perimeter structure is unavoidable. This paper presents a state-of-the-art review on the outrigger system in tall buildings including development history and applications of outrigger systems in tall buildings. The concept of outrigger system, optimum topology, and design and construction consideration will also be discussed and presented.

The Fukushima accident reveals the vulnerability of existing active nuclear power plant (NPP) design against prolonged loss of external electricity events. The passive safety system is considered an attractive alternative to cope with this kind of disaster. Also, the passive safety system enhances both the safety and the economics of NPPs. The adoption of a passive safety system reduces the number of active components and can minimize the construction cost of NPPs. In this paper, reflecting on the experience during the development of the APR+ design in Korea, we propose the concept of an innovative Power Reactor (iPower), which is a kind of passive NPP, to enhance safety in a revolutionary manner. The ultimate goal of iPower is to confirm the feasibility of practically eliminating radioactive material release to the environment in all accident conditions. The representative safety grade passive system includes a passive emergency core cooling system, a passive containment cooling system, and a passive auxiliary feedwater system. Preliminary analysis results show that these concepts are feasible with respect to preventing and/or mitigating the consequences of design base accidents and severe accidents.

The purpose of this study is to devise the concept of properties of the light on learning progressions for 3-6 grade students in the elementary school. For the purpose, this study creates a construct map of the properties of the light. Ordered multiple-choice items were developed in view of the construct map and presented to 200, 3~6 grade students in the elementary school. A partial credit model of Rasch model was used to analyze the results of those items, and the learning progressions was devised from the analysis results. The study can be summarized as follows: the construct modeling approach was used to devise the properties of light on learning progressions. As a result, the concept was selected for the core standards of construct map. Based on the construct map, the multiple-choice items were developed for students' conceptual understanding. The items were analyzed using the partial credit model, and the analysis findings showed that they were appropriate to assess students about their level of understanding of the properties of light. Finally, learning progressions were devised with the use of item analysis results.

Design of web site must include community considerations alongside technical design aspects. The main purposes of this study are to identify the community criteria for evaluating web site and to examine how business web sites include the community factors. To identify the evaluation criteria, the author reviewed recent literatures and made a table showing a summary result(see Table 1). appendix shows a sample form NASDAQ(n=82) and KOSDAQ(n=59) which were evaluated. Using the evaluation from with 189 items(Table 3), all sites were visited and review between August 28, 2000 and September 6, 2000. The auther’s evaluations were done from the perspective of community building in business sector. Table 4, summary data on the results of the study, shows that the level of application of the community concept is very low. Among the listed 18 items, only a few items are utilized at more than 50% level. Less than 10% items are Member Profile, Group Segmentation, Backstory, Forum, Chat, Fact-to-face Meeting, and Collaborative Design. the unbalanced utilization due to the lack of community concept in businesses are found. Korea firms are superior to NASDAQ firms in terms of Bulletin Board and FAQ; But Korean firms are inferior and remain at very low level in terms of Member Login, Education Materials, Backstory, Forum, and Integrating Off-line Activities which are core factors of community building.

The core of character and concept in an exhibition space of contemporary museum is that the place for relics and materials changes into the place for spectators, the static exhibition place changes into the dynamic exhibition place, and the place for learning naturally during amusement. In other words, it could convey the conceptual exhibition object which is not the material object called a relic, it could be a place where is to investigate, participate, experience and enjoy with easily method to general public, and ordinary people are supposed to experience with integrative the world of intellectual, cultural and artistic which is inconcionsly rising a dimensiov. In order to response positively the change of these exhibition concept itself, exhibition system will be established through the analysis of realistic exhibition objects with the visulatization of theme or thought of an exhibitiov. In process of conveying image, the effective and concrete exhibition method and technique should be measured in order to realize the communication between spectators and exhibition objects. The purpose of this study is to find the methodology which is enable to establish the exhibition theme and presentation system through the selection and analysis of exhibition objects in major cases of a musem of ecience and engneering, to find the process model till the methodology applies to the space scheme, and to find finally the designed indicators which is applicable to the progress of exhibition desigv.

Korean goral (Nemorhaedus caudatus raddeanus) is an endangered species in Korea, and the rugged terrain of the Sorksan National Park $(373km^2)$ is a critical habitat for the species. Since the goral population is threatened by habitat fragmentation, it is essential to establish a reserve for the isolated goral population. The objective of this study was to propose a reserve for Korean goral in the national Park We employed habitat suitability model, habitat capability model, and the concept of minimum viable population. The results of the study were as follows. First, the carrying capacity and optimal density of gorals in the national park were projected to be 449 gorals, and 251 gorals, respectively Second, since only one patch was projected to satisfy the criteria of minimum viable population (50 individuals/during 50 years), the long term extinction possibility of gorals in the site would be very high. Finally, the patch that satisfy the minimum viable population of goral was proposed as the core zone of the goral reserve and adjacent patches were included as buffer zones.

This study is carried out for the fire safety of the factory building, the fire risk reduction measure in compliance with an example approached in fire risk reduction systematically, contribute to reduce the fire risk. The analytical fire risk process of discovering, identifying, estimating and evaluating risk and control measure as risk reduction measures are core concept, applies loss prevention with loss control techniques. The painting process in the workplace where the fire hazard and death accident accompanies coexists. Loss prevention problem of creation prevention of dangerous atmosphere at workplace is health and human services problem of normal circumstances, must be inspected with problem of combustible gases at the time of fire explosion. Static electricity measure accomplished the risk control process thoroughly as the fire risk reduction process model with the ignition sources measure which is presented. Fire risk from within organizing will be able to classify with each field by detailedly but risk treatment process will be able to apply basically all the same concept. Consequently about risk management example from before, this study is proposed risk management techniques that standardized rightly in the actual condition of organization with one plan, with discovery of fire risk, the feedback process in compliance with a fire risk reduction and the review which control the result is joint responsibility of engineer, technical expert and manager as part of safety management to practice with the fact must be supervised.

The purpose of this study is to identify the characteristics of the community design ordinance in Seoul as view of the community design activation and to seek improvement. The findings of this study are as followings; Most of the provisions of the ordinance, such as the concept of community design, the basic plan, and the contents of the project, are defined in a similar manner. From the establishment of the concept of community design, it is necessary to establish the regulations that reflect the actual situation and characteristics of the village. In addition to physical facilities improvement, the ordinance should include support for securing space at the core center, which plays an important role in revitalizing community design. Step-by-step approaches are needed to understand the residents at the beginning of the project, because there is not enough practical support related to resident capacity and community solidarity. As the importance of the competent residents increases, the support elements related to humanware areas should also be expanded. In particular, the supporting process and contents for the support system and program for the training of village leaders and the securing of professional manpower should be well established.

In order to identify and describe the central core of fashion desire, the concept of“anti-aesthetics”and“open fashion”were analyzed based on the discourses of postmodernism dis-cussed in the field of sociology, culture, art and philosophy. In this paper, first, the new perspectives of fashion related to modernism and postmodernism were proposed, open concept, anti-aesthet-ics which is ephemerality but eternal ideology. Key principles of postmodernism as anti-aess-thetics mean the philosophy of nihilism proposed by Nietzsche indeterminency, the endd of original art(the death of art), the sublimity provided by Lyotard, and the pluralism to release human from the closed way of thinking, value, ideology. Second, the old and classical definition of fashion,“the differentiation of class”proposed by Veblen and Simmel has been changed into the“differentiation of taste”in postmodern condition. Third, the dichotomous system, that is, ration vs emotion, soul vs body, male vs female, culture vs nature, and so on has been deconstructed and disolved in the postmodern fashion phenomenon using the technique of anti-formalism, such as pastich, parody, bricolage an kitsch for the expression of sublimity and freedom of human.
