In this paper, we provide some fundamental properties and basic theoretical results of K-class-based dedicated storage policy in a unit load system assuming the constant-space assumption that the number of storage locations for a class is not the maximum aggregate inventory position for a class but the sum of space requirement for products assigned to the class. The main theorem is that there exists a (K+1) -class-based storage layout whose expexted single command (SC) travel time is not greater than that of a K-class-based storage layout, i.e, $E(SC^*_{K+1}){\leq}E(SC^*_K)\;for\;K=1,{\cdots}$, (n-1).

The user's needs for the American kitchen space were studied. Especially the remodelings and the desirable changes of the rural kitchen space were examined. Pilot study was carried out by the field survey. Questionnaire with 16 open-end items had been collested bt mail in Missouris, U.S. Based on the qualitative analysis of data for 104 houses. main characteristics of users' needs for the kitchen space can be summerized as follows : 1) The residents had changed or updated materials and facilities, and had enlarged storage space to equip more cabinets. Kitchen space had been adapted to new facilities and appliances. 2) The users still wanted to have larger kitchen space, more storage space and newer floor materials. Through this study it can be concluded that users needed kitchen space to be convenient and wide enough to work.

Wireless Internet, created through the merging of mobile communication with Internet technology, provides the advantage of mobility, but the restrictions of the mobile environment are deterring it from growing into a mass public service. Of the restricting factors of the wireless environment, narrow memory space creates the disadvantage of not being able to manage resources in mobile devices efficiently Because there is a limit to obtaining sufficient memory space from hardware made with consideration of portability, future devices will need to have a platform design with storage area extended from internal storage to external storage space. In this paper, we present a mobile agent that extends the memory space from only the inside of a mobile device to an external server making it possible to use data by on-line Run-time, and can also manage internal files efficiently. We have designed and implemented a RMS(Resources Management System) as a realization. Devices using the proposed RMS will be able to apply extended processes with the 'Mobile Space Extension' and will be benefited with optimal memory space through efficient internal file management.

The distribution logistics center has its own inventory, so designing an efficient storage area is very important. The purpose of this study is to present the optimal storage area calculation method for distribution logistics center considering the use of standard pallet unit load, and the results of this study are as follows. First, standard rack modules for storing T-11 and T-12 type pallet, which is generally used in Korea, were defined. Second, a variety of pallet transport equipments were investigated and analyzed to define the standard transport equipment's work passageway by type. Finally, it has great implications in terms of suggesting measures to minimize unused space that may occur during placement of pallet rack modules within storage space, as well as the easy and optimal calculation of the storage area for the distribution logistics center. Future research require a study on the layout of the entire distribution logistics center, which reflects the latest logistics technologies, such as standard rack modules for Mini-Load and GTP picking system.

Existing non-manifold data structures which use the ordered topological representation method, are designed based on a "Model" which is the highest topological entity. Their non-manifold information is always included in edges and vertices even if they are in the manifold situation. Thus they require large storage spaces than manifold data structures. The proposed data structure reduces its storage space by removing unnecessary information stored in edges and vertices. Topological information is classified into manifold and non-manifold information. The main non-manifold information is radial cycles and disk cycles. The proposed data structure always stores manifold information. For the non-manifold situation, the edge stores radial cycles, and the vertex stores disk cycles. The storage space can be reduced in the later stage of CAD design when the ratio of non-manifold to manifold entities is small.

The purpose of this study is to suggest more efficient modular units of the storage furniture system based on the two previous studies of the apartments storage furniture. This study is also to show the ways and means of making practical use of the results which come from the previous studies. The specific purpose of this study is, 1. To establish the modular furniture system minimizing the dead space, using investigation results of the bedroom size of existing apartments. 2. To establish the modular furniture system maximizing the storage space with utmost efficiency, based on the results of the actual storage condition from the previous research. 3. To suggest a case study of the different modular furniture system suiting 6 different bedroom sizes with the utmost efficiency, based on the results of above two purpose. On the bases of these research results, the design of various units of modular system furniture for bedrooms were suggested.

In modern society, since the expansion of the e-commerce market and the spread of the pandemic, face-to-face business are gradually changing to non-face-to-face. In the logistics industry, the demand for unmanned courier storage is increasing due to lack of loading space from urbanization and courier theft accidents. As the demand for unmanned parcel lockers increases, improved functions such as food storage and efficient space loading are required. This study develops an integrated model-based evaluation procedure of product based on performance factors according to the IEC 61508 standard for newly unmanned parcel storage devices with active loading technology, and derive Critical Technology Element based on the product's core functions and performance goals. As proposing these research, We expect improve the safety and reliability of development targets by identifying and evaluating elements.

This study has been designed to explore the preferences of interior space for those living in apartment housing. It also examines the relationships between preferences of interior space, such as storage space, organization type of LDK(the living room, the dining room, and kitchen), space facing south, an interior garden, the concept of each room and the characteristics of the consumers, such as age, educational background employment status of homemakers, occupation of the primary income provider, family-life cycle, total household income, the size of floor space, and homeownership. In conclusion, this study suggests that at the time of designing apartment housing units, serious consideration should be given to the built-in closets or storage space in the anbang and to the location of a child's room facing to the south of the dwelling, especially for the families with a child attending primary school or younger and higher education level of homemaker. This study also recommends that the organization of the living room, the dining room, and the kitchen should be varied according to the housing size and the age of homemaker.

This study examines changes of internal structure and the ratios of room sizes of flat-type apartment housing and residents' demand of housing alteration. The main results are follows: First, the auxiliary space, such as multi-purpose room, storage ＆ receiving space, becomes an important component of flat-type apartment housing. Second, apartment housings should be supplied to residents focusing on functions of space rather than the number of rooms. Third, the ratios of living room and storage space sizes have been increased as living space increases. Since the current apartment housings do not meet residents' needs, we suggest that residents' age, number of family, and economic status must be considered when apartment space are planned.
