This study aims at efficiency of kitchen management by adoption of a systematic central kitchen and conversion of conventional kitchen to convenience kitchen at ' H ' restaurant. First, integrated menu control of banquet buffet functions became more competitive with quality menu and eventually brought about guests satisfaction. Second, systematic central kitchen made possible standardization and mass production through simplified production line. Efficiency through quick service and shortened preparation time was realized, and food materials were recycled effectively at the same time. Integrated ordering lowered purchasing price and built an efficient cost control system. Third, conversion of conventional kitchen to convenience kitchen and strengthened central kitchen system facilitated agreeable work conditions and optimal work flow with butcher's and even sauce making utensils. Fourth, integrated supply system of buffet menu and sauce from western restaurants saved about 520 million won of labor costs. Last, one integrated kitchen out of two was easier in sanitation control with pleasant restaurant space. Sharing kitchen facilities and equipments also saved about 30% of maintenance fee. Power, water, and gas were also saved and eventually curtailed overall expenses.

In this paper, a method of disassembly time evaluation for a product has been proposed. The product designer can predict the ability of disassembly for a given product in terms of time by considering a type, size, weight, connection parts, and the movement distance of the product. The equation for calculating disassembly time were derived by applying the basis motion status of worker and some informations of connection parts, various tools, and many different type of assembly structures. The developed method of evaluating disassembly time has been applied to disassemble the product by manual labor. The proposed method has shown that the actual disassembly time was well predicted.

In this paper, a shape-based block layout (SBL) approach is presented to solve the facility layout problem with unequal-area and fixed shapes. The SBL approach employs hybrid genetic algorithm (Hybrid-GA) to find a good solution and the concept of bay structure is used. In the typical facility layout problem with unequal area and fixed shapes, the given geometric constraints of unequal-area and fixed shapes are mostly approximated to original shape by aspect ratio. Thus, the layout results require extensive manual revision to create practical layouts and it produces irregular building shapes and too much unusable spaces. Experimental results show that a SBL model is able to produce better solution and to create more practical layouts than those of existing approaches.

Sowing with an automatic seed metering device is increasing in popularity. Since 100% planting is not likely, a major problem is to find any place which contains no seeds between row spacings in the agricultural field. Automatic sowing technology, including the implementation of a microcomputer, appears to be an attractive alternative to the use of manual labor for accomplishing this task. Thus, the multi-purpose seeder attached to a cultivator was designed and constructed with an automatic seed metering device. This seeder proved to be a reliable system for sowing seeds in the agricultural field. Multi-purpose seeder for cultivator consists of an automatic seed metering device, a trench device, a covering device, and a press wheel

VLM-ST process requires an additional human interaction due to the manual stacking and bonding. Hence, building time, building cost and the part quality are dependent on the skill of labor. In this present work, a novel rapid prototyping (RP) process, as an automatic VLM-ST (VLM-STA), has been proposed to improve building efficiency of VLM-ST process and reliability of products. The apparatus of VLM-STA is designed to embody the process. Several characteristics of the proposed process and the apparatus are discussed. In order to examine the efficiency and the applicability of the proposed process, various three-dimensional shapes, such as a piston and a human head shape, are fabricated on the apparatus.

The pulmonary function test (PFT) is an essential data source for evaluating the effect of drugs on the lungs or the status of lung function. However, the numeric values of PFT cannot be easily used for clinical studies without labor-intensive manual efforts, because PFTs are usually recorded as image files. This study was aimed at constructing a de-identified, open-access PFT database with various clinical information. For constructing the PFT database, optical character recognition (OCR), regular expression, and the parsing technique were used to extract alphanumeric data from the PFT images in a Korean tertiary teaching hospital. This longitudinal observational database contains 413,000 measurements of PFT from 183,000 patients.

Purpose: To investigate difference in health status by social classes in Korea through second analysis the 1999 Social Statistic Survey raw data performed by National Statistic Office. Method: 52,100 subjects were 20-64 years old and students were excluded. Health status was measured self-rated health and disease prevalence past 2 weeks. Social classes were classified 5 categories by occupations and working status and 1 category by unemployment. Result: Unemployed people reported the worst self-rated health on average, the lower social classes, the worse self-rated health and higher disease prevalence. Health inequality still existed between social classes after adjusting sex, age, and education level. Conclusion: A certain strategy for improving unemployed people's health and people who are working in craft, simple manual labor, agriculture, fishery, and forestry.

It is important to identify the exact target optical cable that a worker look for when he executes a cable construction work. Until now, An Optical cable identification work has been done by a manual pulling of an optical cable or by the method of using RF signals. But these methods not only consume much time and labor costs but also have a distance limit of the optical cable to identify. In this paper, we propose a method that uses the phase change signal of the optical interferometer to identify an optical cable. With the proposed method the field worker can have an efficient tool to prevent miscutting the optical cable and can also save operating costs.

For labor-intensive sewing industry, productivity could be enhanced with the proper utilization of standard time system. This paper develops a standard data for sewing operations through three stages. The first is to identify the manual motions from sewing operations. The second is to simplify the MTM-1 data considering the frequency and the nature of basic motions occuring in the operations. Finally we synthesize the standard data using the simplified MTM-1 by the film analysis of the actual operations pictured in the field. The standard data developed is shown to be easier and faster with reasonable accuracy in determining the standard time compared to the MTM-1.

The aim of this study is to obtain new design factors which can be applied to the constructing design of bathrooms. This study was especially focused on the using patterns of the bathrooms of the rural apartment houses in Chungbuk Province which have been constructed by the public program to improve old farm houses. To carry out this study, field study, questionnaire survey and personal interview have been made. The results are as follows. 1) It is essential to lay out a bathtub, because farmers need to relieve their fatigue caused by manual labor, and mostly they don't find a bathhouse in the neighborhood. 2) With the drainage way, it is necessary to equip an apparatus to collect and remove the fallen hair and garbage which usually stop up the beak. 3) Considering the using patterns of the bathrooms as the place of washing one's face, foot, hair and clothes, one more hydrant is needed in the bathroom besides the two hydrants in the washstand and bathtub.
