The purpose of this study is to provide a basis for planning of school foodservice facilities to operate with hygiene and efficiency corresponding a decrease of the number of students. This study analyzes the composition of space for foodservice facilities categorizing by the functions which are preparation area, cooking area, cleaning area, storage, and worker's room on elementary, middle and high school in Seoul Metropolitan city since 2009 that the Seoul School Health Promotion Center published a manual for school foodservice facilities. The calculation can be a basis for school planners and the general schools to use available area in each school and can manage the school usage plan appropriately. The number of students in each school has been regarded as the space planning element, but the number of students would considered with using the specific area and time.

Kitchen cabinets are widely used for their spacious storage and efficient use of space, but their high installed location makes it difficult for the elderly and disabled to access. Therefore, in this paper, we propose a new height-adjustable kitchen cabinet that can be used more easily and safely. The lift-down range of cabinet was set considering the installation location of cabinet for efficient use of kitchen space and the maximum height accessible to the elderly and disabled, and the link geometry and driving method of the complex link mechanism were determined through the mechanism design procedure to ensure that the selected floor come down safely along the optimal descend path. In addition, the appropriate motor and control algorithm were added to allow the user to descend to the desired height with a simple button operation. It was confirmed through actual production that the proposed linkage mechanism performs the desired lift-down motion.

In this study, analysis results described in the companion paper was used to determine shapes of room-and-pillar underground structure. To select optimized shapes, structural stability, space applicability and vehicle applicability were considered. In the structural stability step, ratio between strength and stress of the pillar and the critical strain at the roof span were adopted. The space applicability was used to retain the sufficient space of underground structure as its purpose is for human activity. The vehicle applicability was used to consider a radius for rotation of construction equipments in the room-and-pillar underground structure. From the given procedure in this study, proper shapes of rock pillar and room can be selected to design supports at the pillar and roof.

Along with the development of the modern industrial society, quality of food and beverage space has become advanced, individualized, diverse. Especially the sense of diversity has been expressed in many ways to meet the consumer's needs. What the consumers wants from the food and beverage space is to experience gourmet food with the convenience desired. Consumers today are choosy with the practical use of the space with the reasonable price as well as the taste and quality of the food. They also expect light atmosphere at the same time, something extraordinary as well. Therefore, to provide the space for the consumers needs, open-kitchen style has came into the highlights. Open-kitchen is the basic form of serving meals and has become the important aspect of providing the current needs of the consumers. This study will analyze the open-kitchen style of the food and beverage space of the domestic and foreign based on this phenomenon to study their characteristics.

A room-and-pillar underground structure is characterized by its grid-type array of galleries. As a result, its construction and economical efficiency can be governed by excavation sequence of galleries. Therefore, this study aims to study the optimum excavation scheme of a room-and-pillar underground structure by considering its various design factors such as ground conditions and excavation sequences. Drill-and-blast method is assumed as a excavation method for a room-and-pillar underground structure. In addition, two kinds of excavation patterns corresponding to a concurrent and a sequential excavation patterns are considered in this study. For the assumed conditions, the structural stability and the construction efficiency based on the number of faces and the travel distance of a jumbo drilling machine are analyzed for the two excavation patterns. Even though the two kinds of excavation patterns show almost the same structural stability as each other, the concurrent excavation pattern is relatively preferable to the sequential excavation pattern in terms of the number of faces in operation and travel distance of a drilling jumbo.

The grid-type or room-and-pillar method is applied for the purpose of mining horizontally buried minerals. In this study, design and pilot test were performed to apply the room-and-pillar method which uses natural rock as a rock pillar to the construction of underground space. The area where the pilot test was conducted was in stone mine and had good rock conditions with an appropriate depth (about 30 m) to apply the pilot test. The pilot test site was selected by reviewing accessibility and ground conditions and then site construction was performed through detailed ground investigation and design. The pilot test was designed with a column shape of 8×8 m and a cross-section of 8×12 m. The blasting pattern was determined through test blasting at the site, and blasting of 3 m excavation with 89 holes was performed. Through field observations, the average width of 12.5 m and the average height of 8.3 m were measured. Therefore, it is possible to proceed similar to the cross-sectional shape considered in the design.

Most primary and secondary schools in Korea provide school meals to students. After the implementation of the manual in the development of foodservice facilities within schools in the Seoul metropolitan area, this study had been instituted towards the improvement on the design of the school. Through the investigation of the use of school foodservice facilities and the establishment of putting the designer's design to the users into effect, primary and secondary schools have been observed in the study to conclude the following research: Spatial Configuration and Usage Characteristics within Elementary, Middle, and High school.

Room-and-pillar mining method is one of the most popular underground mining method in the world. If the room-and-pillar mining method is able to be adopted in civil works, it would be highly probable to reduce underground construction costs and to expand a underground structure in use. Therefore, this study aims to analyze the design procedure of unsupported rock pillars which are indispensable to ensure the stability of a room-and-pillar underground structure. Parametric studies on their key design parameters are also carried out for 125 different kinds of design conditions. From the study, the width of a rock pillar is found to show a linear relationship with its corresponding safety factor. The safety factor of a unsupported rock pillar decreased drastically like a negative exponential function as the ratio of room width to pillar width increases in the same rock strength condition. Based on the parametric studies, a design chart to simply evaluate the geometric design parameters of a unsupported rock pillar satisfying a design safety factor is also proposed in this study.
