This study was conducted to evaluate the industry foodservice management practices and to suggest guidelines for the effective foodservice management. The survey for the analysis was conducted through the questionnaires to dietitians. They were divided into two groups : the site color worker and the blue color worker. The questionnaires were received for a response rate of 73.2%. Statistical data analysis was completed using the SAS programs for descriptive analysis, $x^2$ test, T-test, F-test, and Fisher's LSD. The results of the study can be summarized as follows : 1) The level of education of dietitians and food cost in the employee feeding operations for the blue color worker was lower than the employee feeding operations for the white color worker. 2) The labor productivity indices were not significantly different according to types of workers. But in the employee feeding operations for the blue color worker, full-time foodservice employees worked more than 10.7 hour per week than their counterpart. This indicates the full-time foodservice employees in the employee feeding operations for the blue color worker performed more loaded work compared to the employee feeding operations for the white color worker. 3) Equipped rate of facilities in the employee feeding operations for the blue color worker was low especially in the food preparation and cooking processes.

The purpose of this study was to evaluate the status of sanitary management based on HACCP. The surveys which were on various aspects of general characteristics, food handling practice, personal sanitation, equipment sanitation, and equipment possession were carried out using questionnaires for 146 business and industry foodservice operations in Taegu and Kyungpook areas. The results of this study were summarized as follows. Forty-nine percent of surveyed foodservice operations was in Taegu, 51% in Kyungpook and 69.2% in direct foodservice operations and 28.1% in contracted foodservice operations. Seventy-eight percent of foodservice operations replied that they have done only basic sanitary management, while 13% surveyed stated that they were implementing HACCP. Food handling practice and personal sanitation were significantly better in Kyungpook area than in Taegu. Significantly high levels in food handling practice, personal sanitation, equipment sanitation, and equipment possession were seen in foodservice operations which had more than 1,000 meal served than those which had less than 1,000 meals served. According to the results of food handling practice, in items of food-temperature measurement during receiving, cooking, holding after cooking, and reheating, foodservice operations showed very low scores below the average. All foodservice operations presented good scores in the parts of personal and equipment sanitation. In equipment possession, sterilizing systems were generally not enough, dishwasher and sterilizing facilities of contracted foodservice operation showed significantly high scores. Therefore, the business and industry foodservice operations will have to pay special attention to temperature management in the foodservice production process as the first step to implement of HACCP.

Optimization of hole-making operations in manufacturing industry plays a vital role. Tool travel and tool switch planning are the two major issues in hole-making operations. Many industrial applications such as moulds, dies, engine block, automotive parts etc. requires machining of large number of holes. Large number of machining operations like drilling, enlargement or tapping/reaming are required to achieve the final size of individual hole, which gives rise to number of possible sequences to complete hole-making operations on the part depending upon the location of hole and tool sequence to be followed. It is necessary to find the optimal sequence of operations which minimizes the total processing cost of hole-making operations. In this work, therefore an attempt is made to reduce the total processing cost of hole-making operations by applying relatively new optimization algorithms known as shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm for the determination of optimal sequence of hole-making operations. An industrial application example of ejector plate of injection mould is considered in this work to demonstrate the proposed approach. The obtained results by the shuffled frog leaping algorithm and proposed modified shuffled frog leaping algorithm are compared with each other. It is seen from the obtained results that the results of proposed modified shuffled frog leaping algorithm are superior to those obtained using shuffled frog leaping algorithm.

This paper suggests a computer software system which generates standard times for assembly products. The system called "computer aided logical system for standard times(CALS4ST)" incorporates a modified bill of materials, BOM4ST(BOM for standard time) to deal with auxiliary operations which are not directly related to parts and assemblies listed in the standard BOM. Typical examples of the operations include inspection, adjustment, and repairing works to be done before or after assembly operations. Once standard time data bases for both the part assembly operations and the auxiliary operations are set up, the system relates the BOM4ST to the standard time data bases so as to calculate the standard time for a assembly part concerned. According to the structure of parts and auxiliary operations in the BOM4ST, their standard times stored in the data bases are to be sequentially added up considering the specified assembly-operation characteristics. To illustrate the feasibility of the system, the case study of L company is provided.

This study analyzes the relationship among environment uncertainty, local infrastructure, flexible-open firm culture, operations performance and marketing performance focus on SMEs. This research has revealed that the relation among firm size, firm type, firm culture, operations performance and marketing performance as well. The findings show that firm has its culture which is preparing environment uncertainty and local infrastructure influence on forming firm culture. Change-oriented and leaning-oriented firm cultures affect operations performance and marketing performance. In conclusion, this study suggests implication and limitations for further research.

Clones are sets of operations which are closed under composition and contain all projections. Identities of clones of term operations of a given algebra correspond to hyperidentities of this algebra, i.e., to identities which are satisfied after any replacements of fundamental operations by derived operations ([7]). If any identity of an algebra is satisfied as a hyperidentity, the algebra is called solid ([3]). Solid algebras correspond to free clones. These connections will be extended to so-called generalized clones, to strong hyperidentities and to strongly solid varieties. On the basis of a generalized superposition operation for terms we generalize the concept of a unitary Menger algebra of finite rank ([6]) to unitary Menger algebras with infinitely many nullary operations and prove that strong hyperidentities correspond to identities in free unitary Menger algebras with infinitely many nullary operations.

This thesis is to investigate the general characteristics of MIS and provides a definite data base for computerization of the division operations based on the analysis and design of personnel business. Therefore, through the analysis of DFD (Data Flow Diagram), DD (Data Dictionary) and SD (System Dictionary), for designing of system, and the analysis of the requirement information, the relationships of business and the process of operations, for the current status analysis of division business, the computerized alternatives corresponding to a choice of a piece of information system were decided. The priority of a developing operations was also determined. A point of view is not so much the study about the division operations so far. This paper will be very helpful and will be achieved through the computerization of MIS.
