While the national economy has rapidly grown, both insufficience in indirect capital facilities of society and attempt to avoid having a logistical job as one of the so-called dirty, difficult and dangerous jobs have resulted in the leak of labor in the logistical industry. First of all, it was shown that the functional utilization level of the logistical information system had a partial effect on the logistical performance, that the reduction of logistical costs was influenced by the information system of connecting and supporting functions, and that the improvement of customer service was significantly influenced by only the supporting-function system. Second, the logistical performance was partially influenced by the linkage between logistical activities, only the customer linkage had a significant effect on the reduction of logistical costs, and the improvement of customer service was influenced by the intra-company linkage. Third, in verifying a hypothesis that the logistical information system's functional utilization level and organizational structure would interact with each other and have an effect on the logistical performance, it was shown that based on their mutual interaction at a normalized level this center's functional information system had a significant effect on the reduction of logistical costs. Fourth, in testing a hypothesis that both the linkage between logistical activities and logistical organization structure would interact with each other and would have an effect on the logistical performance, it was shown that their interaction at a normalized level was significant concerning only the reduction of logistical costs, while there was I10 its significance in the customer service. In proving a hypothesis that the linkage between logistical activities and logistical strategy patterns would interact with each other and would have an effect on the logistical performance, it was shown in a differentiated, aggressive investment one among variously patterned logistical strategies that the customer linkage had a significant effect on the reduction of logistical costs, and in the improvement of customer service that the supplier linkage had a remarkable impact. It also was shown that in case of the cost reduction and offensive control strategy, the customer linkage had a remarkable effect, and th at in the improvement of customer service the intra-company and customer linkage had a significant effect. In the marketing and customer service strategy, finally, there was no any significant influence while the customer linkage had a significant impact in the improvement of customer service. Accordingly, whether or not individual companies utilize the logistical information system's functional utilization levels well will have an effect on their logistical performance, and how their supply chain management is well-linked will affect their logistical performance.

Service part has the attribute causing a difficulty of the systematic management like a kind of diversity, uncertainty of demand, high request for quick response against general complete product. Especially, order picking is recognized as the most important work in the warehouse of the parts since inbound cycle of the service part long but outbound cycle is relatively short. But, increasing work efficiency in the warehouse has a limitation that cycle, frequency and quantity for the outbound request depend on the inherent features of the part. Through this research, not only are the types of the parts classified with the various and specified data but also the method is presented that it minimizes (that) the whole distances of the order picking and store location about both inbound and outbound by developing the model of the demand prediction. Based on this study, I expect that all of the work efficiency and the space utilization will be improved without a change of the inbound and outbound quantity in the warehouse.

With globalization and the development of information and communication technology, the supply chain is becoming more widespread and complex, which increases the occurrence and damage caused by supply chain risks. Supply chain risk management has a great impact on corporate performance through the analysis of risk factors and proactive and strategic approaches. This study aims to analyze the effects of supply chain risk factors on risk management strategies and corporate performance empirically. In the research model for empirical analysis, supply chain risk factors were classified into supply, demand, operation, network, and external environment, while the risk management strategies were divided into active and passive strategies, as well as financial and operational performance for corporate performance. The data obtained via the questionnaire were analyzed for the path of the structural equation model. As a result of the analysis, companies are actively pursuing risk management for internal risk factors, rather than external factors, in terms of internal and external risk factors, and it was found that these strategies have a significant effect on corporate performance. Therefore, in the future, companies should conduct risk management strategies more proactively and preemptively through a thorough analysis of various risk factors affecting business operations.

REITs are very closely related to real estate management, but there have been no prior studies analyzing the location of REITs assets. Therefore, this study analyzed the location characteristics of REITs assets in two aspects to clarify the location characteristics by using spatial information of REITs assets. First, the characteristics of the type of city where REITs assets are distributed were analyzed, and second, the characteristics of the zoning where REITs assets are distributed were analyzed. As a result of analyzing the characteristics of the city where REITs assets are distributed by type, it was analyzed that in the case of the capital area, both the ratio of cities with REITs assets location and the intensity of REITs assets location (number of REITs assets per city) have location characteristics by city hierarchy in the order of metropolitan city > big city > small and medium-sized city. In the case of non-capital area's metropolitan and large cities, the ratio of REITs assets location cities is similar to that of the capital area, but the location intensity of REITs assets was analyzed to be significantly lower than that of the capital area. As a result of the analysis of REITs assets by type, housing REITs assets tend to be located in the old downtown commercial zoning and the new downtown residential zoning, office REITs assets are characterized by concentration of location in specific commercial zoning of Seoul, and retail REITs assets are located mainly in the old downtown station area. In addition, it was found that logistics REITs assets tend to be located in management zoning, centering on key logistics hub cities in the region.

During the Joseon period, space, organization, and personnel were essential in order to perform the administrative work for local governance. For that reason local government records were created, managed, and stored as the results of its administration. Buildings and spaces of local government office can be divided in 3 sections such as 1) administrator's space for governance and living; 2) petty officials' administrative space; 3) granary space for store rations and grains paid as tax. Because of its grand scale, a local government office had considerably complex organizational structure. In order to survey the types and forms of local government records, focusing on six transition documents (junggi, 重記) in the 19th Century Yeongnam Region, this study selected the record type documents in the item lists of the transition documents, then, classified the record type documents which were managed by the organizations in local government offices with several types: program of items (jeolmok, 節目), list of personnel or land (an, 案), register (daejang, 大帳), certified copy (deungnok, 謄錄) and muniment (wanmun, 完文), and examined these documents.

Objective of this study was to investigate the effect of biogas production to different systems and feeding stocks. For the biogas production through operating the temperature phase anaerobic digestion(TPAD) with different feeding stocks, the stage state of biogas production with 70% of methane concentration in the thermophilic digestion tank with co-digestion of food waste and swine manure(40 : 60) was delayed at 3.5 times, but its mesophilic tank was short for 5 days as relative to the swine manure. The cumulative methane production in the thermophilic digestion tank with co-digestion of food waste and swine manure was started with greater than its swine manure at 60 days after digestion periods. However, its mesophilic tank with swine manure was great at 3 days after digestion periods. For aspect of anaerobic digestion processes with swine manure, it was appeared that the stage state of biogas production rate in TPAD was shorter than the two phase anaerobic digestion system.

In Korea, for the past 50 years, industrial parks have played an important role in economic growth as a cluster of national key industries. However, due to various problems of these old industrial parks, they are weakening competitiveness. It is necessary to be converted into a model for the management and fostering of high-tech industrial complex park by classifying them into development plans, management plans, and support plans according to types and characteristics of industrial parks. For this purpose, we propose CIPs (Connected-Industrial parks) using new technologies such as Cloud Computing, RFID, WSN, CPS, and Big Data analysis based on IoT. It is a hub that supports various services in transportation, warehousing and manufacturing fields while possessing and operating physical assets as concept. each CIP (Connected-Industrial park) is connected and expanded Through such CIPs, network-type collaborative manufacturing and intelligent logistics innovation enables cost reduction, delivery shortening, quality improvement.

A cold storage is a warehouse of a insulated building with cooling installations. It has many different types of cold rooms with temperatures below 0 degrees Celsius, and the sequential workflow such as receiving, picking and packing runs in that rooms. Recently, the cold storages have adopted RFID technology, and consequently, warehouse product management in them are becoming intelligent and network. However, information inconsistency in warehouses caused by physical and logical errors reduces reliability in the RFID cold storage management system and worsens their work efficiency. Therefore, it is necessary to develop an early detection system to identify errors. In this paper, we suggest a supervisory system detecting logical errors on business processes of the RFID cold storage. It is composed of a master supervisor and mobile supervisor. In the master supervisor, the manager can set the constraints conditions and get alerts, and in the mobile supervisor, the workers confirm and deal with these faults directly. The supervisory system improve reliability of the RFID cold storage management system by recognizing a failure to identify physically and logically using these constraint conditions. This paper shows that the supervisory system can reduce the average recovery time to improve reliability by decreasing the time for detecting and analyzing errors in the RFID cold storage management system.

This study compares own-brand exporting SMEs' utilization of various government-run exporting service programs that provided support in searching for overseas distributors, in overseas market research, and in marketing support. Researchers measure how important firms found each of these components of the program, as well as firms' satisfaction with these services, based on the type of product exported (industrial vs. consumer goods) and the level of economic development of the host countries (developed, newly industrialized, and developing.) A total of 245 own-brand exporting SMEs were surveyed and analyzed in this study. Results indicated that KOTRA was the most frequently used organization by the sample SMEs, regardless of the product type and the economic level of host countries. Industrial-goods exporting SMEs found support in searching for overseas distributors more important than consumer-goods exporting SMEs. SMEs exporting to developed countries considered overseas market research and marketing support and searching for overseas distributor programs more important than SMEs exporting to NIE or developing countries. In addition, industrial-goods exporting SMEs were more satisfied with the overseas market research and marketing support and searching for overseas distributor programs than consumer-goods exporting SMEs. However, there were no differences in satisfaction among firms based on the level of economic development of host countries. Several cases of significant correlations between the importance of and satisfaction with the utilization of government exporting service programs were found.
