How to measure and evaluate the performance of managing a store? Although it is important for a retailer to execute good management in a store, there are few efficient measurement tools and methods for In-store management. Also few people are trying to deal with variety of goods (number of categories), depth of a catagory (number of stock-keeping units within a category), and stock level (the number of individual items of a particular SKU) in a store. To solve the problem, this paper suggests the Customer-Retailer Collaboration (CRC) model that utilizes Gamification. By embedding gaming elements, the store management activities can be viewed as more game-like processes. Customers find some problems they encountered in the store and send the related signals via mobile APP, and the relevant store personnel copes with the signals. As the return for their collaboration, they both will obtain points and badge. This paper designs the CRC model and shows the flow of the model briefly.

This study aimed to determine the management and environmental factors affecting medical expense reduction. For analysis, medical expenses were divided into hospitalization expenses and outpatient treatment expenses, and the rate of medical expense reduction was classified into initial and final reduction rates. Data were collected through a direct survey among 205 directors of independent health insurance review departments of hospital-level medical institutions in Korea. The results of the study are discussed below: In the analysis, differences in the initial and final reduction rates of hospitalization expenses and outpatient treatment expenses were compared. The results showed that, in hospitalization expenses, the initial and final reduction rates were both significantly affected by the following management factors: number of beds, number of departments, number of personnel reviewing health insurance cases, and total number of employees. Further, in outpatient treatment expenses, the initial and final reduction rates were both affected significantly by the following management factors: management of medical records, number of beds, number of departments, number of personnel reviewing health insurance, and total number of employees. The management factors significantly affecting both the initial and final reduction rates were higher number of beds for hospitalization expenses and electronic medical record management for outpatient treatment expenses. The environmental factors significantly affecting both the initial and final reduction rates of hospitalization expenses were a highly cooperative work environment, better implementation of indicator management systems, and overtime pay. Better implementation of indicator management system and a committee for handling medical expenses had significant effects on the initial reduction rate for outpatient treatment expenses. A highly cooperative work environment, better implementation of indicator management system, and overtime pay had significant effects on the final reduction rate for outpatient treatment expenses.

Recently, natural disasters due to abnormal climates are frequently outbreaking, and there is rapid increase of damage to aged agricultural infrastructure. As agricultural infrastructure facilities are in contact with water throughout the year and the number of them is significant, it is important to build a maintenance management system. Especially, the current maintenance management system of pumping and drainage stations among the agricultural facilities has the limit of lack of objectivity and management personnel. The purpose of this study is to develop a performance evaluation model using the factors related to performance degradation of pumping and drainage facilities and to predict the performance of the facilities in response to climate change. In this study, we focused on the pumping and drainage stations belonging to each climatic zone separated by the Korea geographical climatic classification system. The performance evaluation model was developed using three different statistical models of POLS, RE, and LASSO. As the result of analysis of statistical models, LASSO was selected for the performance evaluation model as it solved the multicollinearity problem between variables, and showed the smallest MSE. To predict the performance degradation due to climate change, the climate change response variables were classified into three categories: climate exposure, sensitivity, and adaptive capacity. The performance degradation prediction was performed at each facility using the developed performance evaluation model and the climate change response variables.

Performance evaluation continues to receive attention today as it has for the past few decades. The problem addressed in this paper concerns the relationship between supervisor's causal attributions and their subsequent responses behavior. Previous study in personnel and other disciplines has indicated the importance of causal attributions in the interpretation of poor performance. However, most study has focused on antecedents of attributions than supervisor's responses to the subordinate's poor performance. The objective of this study was to investigate the effects of supervisor's causal attributions and subordinate's responses to a subordinate's poor performance. Specifically, using in the public sector context, the study examined the effects to two dimensions of causal attributions: locus of causality and stability, as well as on the punitiveness of supervisors's responses. The result supported that when the subordinate is internal causes for the performance failure, supervisor's responses were more punitive. Consistent with previous studies, internal attributions were found to result in more punitive behavior than external attribution. In addition, attributions to effort and luck were found to result in more punitive behavior than attributions to ability and task difficulty. Thus, the first hypothesis and second hypothesis supported. These result suggest the importance of appropriately for performance evaluation.

The Busan shoe industry has been the accelerating overseas transfer of production facilities due to loss of competitiveness in the wake of drastic revaluation of the won, an increase in personnel expenses and the rise of backup developing countries since the late 1980s. On account of changes in the general system of supply and demand caused by a decrease in exports and production, the Industrial structure has been subjected to a transition from export to domestic demand. As a result, the Busan shoe industry, which used to rank second in the world in terms of its shoe export and to account for 16.5% in terms of its market share, started to be regarded as a fast-fading industry. As a domestic companies have a tendency to almost all the tasks on bloc, it is true that their competitiveness is on the rapid decline for they prefer self-reliance on the premise that all the production should be dealt with for themselves. It is outsourcing that is taken into account as a strategic vehicle for converting such self-reliance into the system of low expenditure and high efficiency.

The system proposed in this paper is a fully automated parking control system that can even protect users' information through blockchain. Unlike conventional parking control systems, the system consists of a web page that is accessible to people of all ages and ages, directly to the parking lot. Such a system would also benefit managers in the parking lot business. This is because it can reduce soaring labor costs and maximize the sales it can generate by operating 24 hours a day. In order to implement these systems, the web page was first designed using HTML and the API was configured using JAX-RS to invoke the API required by the web page. As a result, it created a web page that was easily accessible to anyone, built a server that could be accessed by more than 200 people at the same time, focused on personal information protection by encrypting the information of users through blockchain grafts, and designed a system that enabled users to complete payments easily. It is planning to add QR codes and GPS functions in the future and implement a function that allows one-touch information on parking lots and their vehicle information.

Despite prologed business stagnation of both international and domestic economy, hotel business as well as tourist industry has continuously been keeping growing, owing to increase of surplus income and world flowing population. During recent 4 years, growth rate of yearly mean in domestic hotels reached 9.9% and especially that of the superior class hotels 15.2%. In the composition of domestic tourist hotel's revenue, the earnings of guest rooms form 37.4%, on the other hand those of food & beverage 39.9%. This result is that our hotel business is concentrated on its interest in FOOD & BEVERAGE of which productivity per unit dimension can be increased to an unlimited extent and extent and superior class hotels strengthened in F&B are increasing in comparison with European or American hotels which are focused on guest rooms in their management. For value added rate of F&B is low as compared with increase of their earnings, they are interested in the management techniques which focus on rising the rate. As for the cost of Food & Beverage, personnel expenditure forms 36.5% and the direct materials 31.5%. Therefore how to manage personnel and materials costs which compose as much as 68% of total revenue will greatly affect net profit. We can say that an effective management technique in cost of Food & Beverage is one of the most important know-hows in hotel management. Especially management know-how for the Kitchen Department where the most of foods come out makes a great effects on various expenses, productivity and it is the achievement from hotel management. For the most of the hotel's top managers, they don't seriously take the fact that KITCHEN SYSTEM affects greatly total expenditure. This study starts from the point of recognizing the question of fundamental cause affecting tow largest cost elements incurred in Food & Beverage and trying to present an effective kitchen system. To settle the questions raised, I compared and analyzed productivity and cost of food & beverage and unit kitchen centered around superior class hotels in Seoul, which vary in Kitchen Systems. In order to attain the aforementioned study effectively purpose of this study, I compared Room-Service and Coffee-Shop Menu, flow of basic food in the kitchen, extent and result of division of labor and integration in the kitchen, scale of outlet kitchen, productivity, the turnover rate of food in store, food cost rate one another which all vary in Kitchen Systems. All these elements are compared and analyzed each other being divided into two main groups such as①. Main Production kitchen and Banquet Kitchen, and ②. coffee-shop kitchen and Room-service Kitchen. Therefore this study is to point out the problems in managing kitchens of superior class hotels which are different in systems. An effort was made to find out the better Kitchen System for superior deluxe hotels. I emphasize the followings on the proper scale of division of labor and integration of unit kitchen and a disposition plan for outlet kitchens of restaurant. First, KITCHEN SYSTEM as a sub-system of Hotel Management System is composed of sub-systems of outlet unit kitchen. Basic food materials are cooked and served for the guests while support kitchen and out restaurant kitchen interact organically each other. So Kitchen should be considered as a system composed of integrated sub-systems. Second, support and banquet kitchens should be integrated to be managed. And these unit kitchens have to be designed to be placed in the back of banquet rooms area. Third, coffee-shop kitchen and room-service kitchen should be integrated to be managed. Fourth, several unit business kitchens should be place on the same floor. Fifth, main production kitchens ought to be located near the loading duck, food store and large refrigerator. Sixth, considering the limits of supervision, duties should be adjusted as 12-20 cooks in two shifts a day for a sub-kitchen, and 18-30 cooks in three shifts a day so that labor division can be made. Last, I would like to two points for direction and task of future study. Firstly, I compare the effective income and increasing costs each other, which are incurred by increasing the use rate of the second processing materials for foods perched outside and through the results. I can find out the better points of the processing production and circulation system, and then I study this effects made on hotel kitchen system. Secondly, I can point out that more efficient kitchen system shall be established through comparing and analyzing the matter of amount of indirect costs and flow of food in different kitchen systems.

Electronic paper resources management becomes an important alternative to overcome the inefficiency of various dysfunctions and pathologies dependent upon bureaucratic paperworks and to enhance organizational competitiveness. Korean government and enterprises have less recognized the importance of electronic document management and ignored the merits of introducing information technology into organizations. By means of document and paper exchange, decision making and signature, mail and bulletin board systems, information disclosure and sharing using electronic technology, however, electronic document management system can enhance organizational performance on a considerable degree. In this sense, it is necessary to introduce the system as soon as possible. Several measures are required : revising related laws and regulations, reforming the sense and behavior of personnel, establishing technological basis of the system, standardizing word processors and document formats.
