This article discusses a capacity planning method in QoS-guaranteed IP networks such as BcN (Broadband convergence Network). Since IP based networks have been developed to transport best-effort data traffic, the introduction of multi-service component in BcN requires fundamental modifications in capacity planning and network dimensioning. In this article, we present the key issues of the capacity planning in multi-service IP networks. To provide a foundation for network dimensioning procedure, we describe a systematic approach for classification and modeling of BcN traffic based on the QoS requirements of BcN services. We propose a capacity planning framework considering data traffic and real-time streaming traffic separately. The multi-service Erlang model, an extension of the conventional Erlang B loss model, is introduced to determine required link capacity for the call based real-time streaming traffic. The application of multi-service Erlang model can provide significant improvement in network planning due to sharing of network bandwidth among the different services.

This research used Analytic Hierarchy Process(AHP) to analyze the importance and priority of functional space and evaluation factors of each functional space of the military dining facility. Dining in the military is an important factor in restoring combat power and promoting morale. The military dining facility serves as a not only for meals, but also for watching TV, education and club activities. Workers working in dining facility spend most of their work hours in dining facility, perform tasks such as cooking, dishwashing, and leftover disposal, and take breaks. As such, the military dining facility is a space where various functions are performed, and space planning should take into account these various functions when planning the building of the dining facility. However, the criteria for defense and military facilities, which are the basis for planning the space of military dining facility, are calculated only by simply analyzing the standard floor plan to match the size of the person-to. Therefore, when there is space to be reduced in the total area, there are side effects such as leaving visible table space without consideration for priority or functional space, unseen office space, and adjusting the entire area through reduction of the lounge. Accordingly, based on the priority of the space that the staff of the military dining facility considers important, this research aims to analyze the characteristics of each functional space through classification according to its unique function. This can be an indicator that can be used as a basis for future revision of the building floor area standards of the defense and military facilities standards, and it can improve usability with an efficient space plan that takes into account the characteristics of the Korean military and the satisfaction of its workers. Furthermore, efficient use of the defense budget through rational building plans can contribute to budget reduction.

This study analyzes the common space of the high schools before and after the decade of 2009 which starts Subject-centered clusters school plan, and proposes the direction of common space planning for the future. Based on the floor plans of high schools awarded as excellent school facilities every year, first, types and numbers of common space, second, area ratio between common space and program space and also moving space and staying space, third, space connections were analyzed for tracking the change of the relationship between common, staying and program spaces. The study results demonstrated that types, numbers and area ratio of the common space were increased as the years go on. Especially, the area ratio of staying space was dramatically increased after 2009 and this result was caused by the home-base, alcove space, and hall that were adopted for subject-centered clusters planning after 2009. Connecting diagram of staying area and program spaces also shows the spaces related to staying area were changed from a classrooms and administrative office etc. to a library, gym, and seminar rooms etc. In case of staying area, it would have a value as a common space for various student activities such as group activities, meetings, and multi-uses. Because student activities would be changed and encouraged depending on the location, sizes and program spaces around staying area, it should be emphasized that the planning for staying area is critical for future school design.

The purpose of this study is to clarify the actual condition of the layout and floor planning of elementary schools for the 7th education curriculum. This article discuses about the basic characteristics of the plan composition and the outdoor spaces of 35 elementary schools in Gyeongnam prefecture. The results of this study are summarized as follows; 1) To respond to the 7th educational curriculum, unit classrooms need to be expanded or space for a multi-purpose room needs to be secured to serve the following purposes: the operation of educational program by the level and offering of unified Subjects. overall, elementary schools need to seek ways to deal with problems associated with space composition, types of classrooms, and changes in the number of classrooms so that the 7th Educational curriculum can be carried out smoothly. 2) Different from the past, various plan types are available nowadays. Even in case of schools with the same class size, their areas were different by 130 percentages or higher. Therefore, practicality needs to be more focused than facility standards in order for the school to cope with changes in future educational environment. 3) When designing the elementary school in the future, more space needs to be assigned for learning by expanding facilities - special purpose classrooms and supporting facilities - to accommodate students' various learning activities. In addition, faculty facilities need to be rearranged to promote research and development as well as to ensure the operation of the educational program. And, resident facilities that consider the close connection with the local community need to be rearranged in an efficient manner as well.

During the course of play, children gain special experience in a place where they can explore their surrounding environment and feel emotional stability. This experience of attachment to the place of play is very important in that play can serve as a measurement of the child's growth and development. Therefore, the environment surrounding the child should be understood as a meaningful place that affects a child's life beyond the place of play. The purpose of this study is to propose a spatial planning method where the formation of place attachment is considered in the design of child care facilities, as this is where preschool children spend much of their early formative years. The research methods are as follow: First, we surveyed the relationship between child development and place attachment through literature reviews and found that the factors that form place attachment were summarized as accessibility, complexity, segmentation and nature friendliness. Second, we examined the spatial characteristics of Mitsuru Senda, a Japanese architect who has been intensively studying children's play environments, as well as the characteristics of children's play proposed by his academic research. Finally, we analyzed the relationship between the spatial characteristics supporting play shown in Senda's work, and the four factors of place attachment formation and proposed a planning method for space design applicable to child care facilities.

The recent advances in digital technology allow the use of BIM for integratively managing various information pertaining to an architectural structure. This can be the suitable tool for effectively utilizing the various requests of both the users and the administrators from the planning phase. In particular, planning and constructing a school facility can be challenging because it is an important learning facility where the students are required follow a set schedule. Accommodating to the various needs and requests of the users and the other related parties in the progress can be very difficult. Therefore, in order to use the BIM with the basis of data to manage the lifetime of the school facility, it is necessary to develop the specialized BIM process customized to the school facilities. Using this as the base, the BIM process specifically for school facilities should be phased in, applied, and expanded. The objective of this study is to define the scope of application and to plan for the efficient utilization of the BIM process specialized for school facilities, when conducting the project from planning phase to design development phase through the series of processes. Unlike the presently used enhancement of the visible minute details of the models, the methods to enhance the quality of information contained inside the model will be proposed. Also, the user will participate in the school facility construction. The realistic BIM application is aimed through the research for the processes for building models that will be utilized for construction and management.

The purpose of this study is to configure the spaces and elements of the roof-garden plan that users regard as important, and to investigate their preferred spaces and facilities, ultimately providing basic information for the planning of user-directed roof gardens for local residents. A questionnaire survey was used as the research method, targeting roof-garden users in the L department store of Jeollabuk-do. A total of 225 people responded to the questionnaire, and 223 of them were used for this study. The collected data was analyzed in SPSS ver.18.0, using frequency, percentage, t-test, and one way ANOVA. The respondents preferred rest space the most, followed by the convenient space, landscaping and green space, and play and exercise space. Teenage students preferred the pool and artificial spaces, such as a fountain, and planned convenient spaces and rest spaces, such as a playground. Cafes and restaurants, chairs and tables, and walking trails should be considered for single women in their twenties. Due to the high population of married couples in their thirties, the preference for play facilities and safety facilities was higher than in other groups. The well-educated population in their forties, when viewed from their preference for landscaping and green space, requires the opportunity to rest in nature. The results of this study cannot be generalized since the study was directed at roof-garden users in a department store in Jeollabuk-do. However, it is possible to provide specific information about the user-directed roof-garden plan, since the study was analyzed together with various user variables.

This study examines the relationship between the usage of public bike and physical environment factors around the public bike stations using the public bike rental history data from 2016 to 2017 in Seoul, Korea. Focusing on the different influences of determinant factors by distance to public bike station, this study identifies influential factors that affect the usage of public bike. The results of the analysis are as follows. First, both the land use and physical environmental variables of bike station areas show strong associations with the usage of public bike. Second, the usage of public bike is also associated with neighborhood living facilities, business facilities, land use mix, the distance to subway station, public facilities and universities. This finding indicates that public bike has played a role as a transportation mode for the short-distance travel and commuting purposes in everyday life. Third, this study shows that the usage of public bike is strongly associated with the average slope, traffic volume around public bike stations, distance to streams or rivers, and the types of bike lane. This finding also indicates that surrounding environmental factors play an important role in the usage of public bike. Finally, this study identifies the different influences of determinant factors on the usage of public bike by distance to public bike station. This study suggests policy implications for the potential locations of public bike stations in the future.

This investigation aims to provide basic data for rural village planning and rehabilitation planning. Public infrastructures of forty selected villages have been surveyed. Provision of facilities, user satisfaction, perceived problems, and conditions of maintenance have been surveyed for three classified types of infrastructures; 1) public utility spaces such as community hall, and parking lots, 2) public production infrastructures such as warehouses, and irrigation facilities, and 3) public infrastructures for living environments such as roads, water supply, and sewage system. All twenty smaller villages (ki-cho-ma-ul) had problems of poor conditions and insufficient spaces with community halls. Most of the smaller villages suffered from lack of public production infrastructures, or had problems of insufficient spaces and poor maintenance conditions. They also lacked good access roads with adequate right of ways. Only three villages were provided with sewage systems. In the twenty larger villages (myun-bo-ma-ul), though public utility spaces were provided for most of them (as an example, sixteen villages had welfare centers), they were not large enough and they were maintained in poor condition too. On the one hand twelve of the larger villages had farm machine service centers, only a few villages were equipped with warehouses. Many more public infrastructures for living environments were found in larger villages. However, only a few villages had pollution control facilities. Multidimensional scaling revealed groups of distinctive characteristics, in terms of public infrastructures, among smaller villages. It did not show any noticeable distinctions among larger villages.
