Network human-robot interface is an important research topic. In home application, users access the robotic system directly via voice, gestures or through the network. Users explore a system by using the services provided by this system and to some extend users are enable to participate in a service as partners. A service may be provided by a robot, a group of robots or robots and other network connected systems (distributed sensors, information systems, etc). All these services are done in the network environment, where uncertainty such as the unstable network connection, the availability of the partners in a service, exists. Moreover, these services are controlled by several users, accessing at different time by different methods. Our research aimed at solving this problem to provide a high available level, flexible coordination system. In this paper, a multi-agent framework is proposed. This framework is validated by using our new concept of slave agents, a responsive multi-agent environment, a virtual directory facilitator (VDF), and a task allocation system using contract net protocol. Our system uses a mixed model between distributed and centralized model. It uses a centralized agent management system (AMS) to control the overall system. However, the partners and users may be distributed agents connected to the center through agent communication or centralized at the AMS container using the slave agents to represent the physical agents. The system is able to determine the task allocation for a group of robot working as a team to provide a service. A number of experiments have been conducted successfully in our lab environment using Issac robot, a PDA for user agent and a wireless network system, operated under our multi agent framework control. The experiments show that this framework works well and provides some advantages to existing systems.

In this research, I finally came to a conclusion analyzing the connection among managing of each items in management expenses, the size of each complex and stories, and the term of using. (1) In the managing cost regarding to the management manner, although the managing cost of self-governing management is less imposed than the one of commission management, there is slight difference between those Costs. And it is more important to consider the effectiveness of management than to emphasize reduction of management cost. (2) The higher the stories, the higher the managing cost of elevator per the unit area. It Is caused by the fact that the father the distance of the elevator operating, the higher the electric charges. (3) The third of one of total management cost goes to pay the personnel expenses. So I found that the effective management of the expenses is available to reduce management cost. (4) The higher the stones, the lower the cost of personnel expenses including the cleaner cost. (5) The sum of costs assigned in repairment and management increases in proportion to the term of using. The costs assigned in special repairment and management are interacting to each other. (6) To reduce the management cost, we have to cut down the personnel in security guard that occupies one third of total management cost with application to the joint security system and operation of the self-governing guard. Through this process, it will be easy to accomplish the rationalization of contract with an outside order. Because the improvement of management service is not only the responsibility of owner but also the one of dwellers. And it Is imperative to realize the importance of cooperation and trust between the owner and dwellers. And the establishment of effective managing system which has convenience and rationality must be settled without delay.

Appointment of arbitrators is very important in arbitration. As it has been a long laps since Korean peninsula was devided into two parts, South and North, it has come to be too much gaps between South and North in the law, social system, commercial practice and etc.. South Korea is familar to international commercial practice and capitalistic legal system generalized internationally in modern times. On the other hand as North Korea was closed society for a long time, they are not familar to international commercial practice and market economy. In this connection, commercial disputes arising from the transactions between South and North will occur frequently and it will be very difficult to select governing law or commercial practice referred to the disputes. Under the circumstances, when and if an arbitrator from South or North will be appointed as presiding arbitrator in the tribunal composed by three arbitrators, the part from which the presiding arbitrator come will be a majority, and it will be advantageous to the parties came from the part of which the presiding arbitrator come from. Such being the case, sole arbitrator or presiding arbitrator needs to be appointed among foreigner. Otherwise I recommend the tribunal composed by two arbitrators and umpire system. As to arbitrator's fee, as there is a big gap in its economic aspects between South and North, I supposed to need establishing the fund made by corporation with South and North in order to compensate arbitrators from South or abroad for their fee. Finally it is more important to prevent disputes arising from transactions between South and North. In order to prevent the disputes, education for North Korean about international commercial practice and skill to make a contract of international sale of goods and investment are needed.

The purpose of this study is to clarify the historical circumstances under which the Korean Pavilion was established at the 1900 Paris Exposition Universelle, and the construction process and design features of the pavilion building. At that time, even though Korea faced difficulty due to lack of experience in the world exposition and funds, Korea attempted to positively participate in the international cultural event by establishing the Korean Pavilion under an official contract with assistance of the French Government. Moreover, the Pavilion shows significant architectural features which had not been shown until then in terms of the structure and design of the pavilion building. In this connection, in this thesis, among others, the historical circumstances under which the "Korean Pavilion" was established at the 1900 Paris Exposition Universelle, and the construction process as well as the process and features of the draft design prepared at an early stage by Baron Delort de Gleon on the part of France among the above parties to the project for construction of the Korean Pavilion, which have never been addressed in the field of architecture or interior due to lack of existing data, will be clearly studied based on relevant literatures. According to analysis of the study, it reveals that the representation method for the Korean tradition of Korean Pavilion designed by Baron Delort de Gleon was based on the Chinoiserie, the style widely seen in Europe. In addition, Delort de Glean's commerce-oriented concept is integrated into the design of the Korean Pavilion as well.

The large amount of data that emerges from the initial connection environment of the Fourth Industrial Revolution is a major factor that distinguishes the Fourth Industrial Revolution from the existing production environment. This environment has two-sided features that allow it to produce data while using it. And the data produced so produces another value. Due to the massive scale of data, future information systems need to process more data in terms of quantities than existing information systems. In addition, in terms of quality, only a large amount of data, Ability is required. In a small-scale information system, it is possible for a person to accurately understand the system and obtain the necessary information, but in a variety of complex systems where it is difficult to understand the system accurately, it becomes increasingly difficult to acquire the desired information. In other words, more accurate processing of large amounts of data has become a basic condition for future information systems. This problem related to the efficient performance of the information system can be solved by building a semantic web which enables various information processing by expressing the collected data as an ontology that can be understood by not only people but also computers. For example, as in most other organizations, IT has been introduced in the military, and most of the work has been done through information systems. Currently, most of the work is done through information systems. As existing systems contain increasingly large amounts of data, efforts are needed to make the system easier to use through its data utilization. An ontology-based system has a large data semantic network through connection with other systems, and has a wide range of databases that can be utilized, and has the advantage of searching more precisely and quickly through relationships between predefined concepts. In this paper, we propose a defense ontology as a method for effective data management and decision support. In order to judge the applicability and effectiveness of the actual system, we reconstructed the existing air force munitions situation management system as an ontology based system. It is a system constructed to strengthen management and control of logistics situation of commanders and practitioners by providing real - time information on maintenance and distribution situation as it becomes difficult to use complicated logistics information system with large amount of data. Although it is a method to take pre-specified necessary information from the existing logistics system and display it as a web page, it is also difficult to confirm this system except for a few specified items in advance, and it is also time-consuming to extend the additional function if necessary And it is a system composed of category type without search function. Therefore, it has a disadvantage that it can be easily utilized only when the system is well known as in the existing system. The ontology-based logistics situation management system is designed to provide the intuitive visualization of the complex information of the existing logistics information system through the ontology. In order to construct the logistics situation management system through the ontology, And the useful functions such as performance - based logistics support contract management and component dictionary are further identified and included in the ontology. In order to confirm whether the constructed ontology can be used for decision support, it is necessary to implement a meaningful analysis function such as calculation of the utilization rate of the aircraft, inquiry about performance-based military contract. Especially, in contrast to building ontology database in ontology study in the past, in this study, time series data which change value according to time such as the state of aircraft by date are constructed by ontology, and through the constructed ontology, It is confirmed that it is possible to calculate the utilization rate based on various criteria as well as the computable utilization rate. In addition, the data related to performance-based logistics contracts introduced as a new maintenance method of aircraft and other munitions can be inquired into various contents, and it is easy to calculate performance indexes used in performance-based logistics contract through reasoning and functions. Of course, we propose a new performance index that complements the limitations of the currently applied performance indicators, and calculate it through the ontology, confirming the possibility of using the constructed ontology. Finally, it is possible to calculate the failure rate or reliability of each component, including MTBF data of the selected fault-tolerant item based on the actual part consumption performance. The reliability of the mission and the reliability of the system are calculated. In order to confirm the usability of the constructed ontology-based logistics situation management system, the proposed system through the Technology Acceptance Model (TAM), which is a representative model for measuring the acceptability of the technology, is more useful and convenient than the existing system.

The regulation of business area was abolished to improve the competitiveness of the construction industry and the ability of general and specialty contractors to enter the mutual market. As the next step, the government is preparing for a reorganization of business type. If the impact of the abolishing of business area on the construction industry is analyzed, the result can contribute to determining the step by step application scope of the reorganization of business type. This study derived the business types having a high probability of the mutual market entry of general and specialty contractors. Then, the size of mutual market entry is analyzed. First, the connection between the general and specialty construction, and the similarities between the registration standards of general and specialty construction are analyzed. Based on the result, a general contractor can enter 15 business types of specialty construction, and the market size is about 78.8 trillion KRW. This is about 82% of the total contract cost of specialty construction during the year 2017 (about 96 trillion KRW). Next, based on the relevance of business contents, the market size when general contractors enter the specialty construction market is analyzed. As a result, the market size is about 24.7 trillion KRW, and this is about 13% of total contract cost of general construction during the year 2017 (about 190 trillion KRW). Based on the result of this study, there is a higher probability of the mutual market entry of general contractors into specialty construction than vice versa. However, the result of this study is based on the current contents of business types, registration standards, and construction data of before abolishing the regulation of business area. This is a research limitation. If the business contents and registration standards are changed in the future, the result could differ from the current result.

This study analyzed the effects of the relational norm factor of food service franchising on the intention to remain, in view of the importance of relational norms, as antecedent variables, to franchisees' perceived fairness to enhance the competitiveness by formation of long-term relationship between interested parties to food service franchising, the franchiser and the franchisee. According to a questionnaire survey, more than 100 franchisees that recorded three business years in Seoul, Incheon and Gyeonggi area were selected for convenience sampling. Then, among them, 515 effective samples were analyzed. For statistical data, detailed types of analysis were performed by using AMOS 17.0, such as factor analysis, exploratory factor analysis, confirmatory analysis and frequency analysis. The purpose of this study was to examine the relationship between the franchiser and the franchisee by arranging relational norm factors for the relationship to be suitable for the current situation of Korea, instead of Western-style theory-based relationship marketing, and by understanding a connection between perceived fairness and management achievement-related variables, and to make a conceptual framework for building a positive relationship between the franchiser and the franchise in future food service franchising industry. Moreover, it aimed to increase franchisee satisfaction and results including re-contract according to perceived positive relationship value on the franchiser and to make contribution to find and show the proper direction for development of the Korean-style food service franchising system.

The purposes of this study were to identify the dimensions of perceived dissatisfaction, complaining behavior, and long-term orientation of customers about the Internet fashion shopping mall, and to empirically examine the effects of each dimension of perceived dissatisfaction and complaining behavior on long-term orientation. For this study, questionnaires were administered to 275 Internet shopping mall customer. To analyze collected data, descriptive analysis, factor analysis, Cronbach's $\alpha$, correlation analysis, and regression analysis were used. Major findings were as follows. First, college students were found to mainly complain of dissatisfaction at product quality, refunding/changing/maintenance repair, price, contract, delivery, and payment after transaction with the Internet shopping mall. Second, customer dissatisfaction was found to have high correlation with complaining behavior and partly with customer neglect or exit. Third, higher customer dissatisfaction was found to increase customer complaining behavior in general. Finally, higher complaining behavior was found to have connection with lower customer loyalty and higher customer neglect and exit.

This study represents something in common and differences of organic characteristics between early modern architecture and contemporary architecture analysing F. L. Wright's Robie House and Toyo Ito's Sendai Mediatheque. A natural organic body cannot be separated from the natural environment, and each part of an architecture has each own property and forms a whole at the same time. That is a basic concept of organic architecture, and a framework for analysis is set up based on it. The followings are similarities and differences of organic concept and interpretation between Wright's Robie House and Ito's Sendai Mediatheque First, Wright' Robie house unites with the natural surrounding, using a physically close connection to the ground. In contract, Ito's Mediatheque shows characteristics of noncentural and fluidic space that are metaphorically reflecting tangible and intangible of factors in modern city, where there is an ambiguous physical boundary between architecture and urban environment. Next, floors, walls and ceilings of Wright's housing as for basic building blocks are physically separated and at the same time form formative unity from the point of view of a physical and structural organic body. And continuous flow of faces of separated walls form an organism united with the nature from a physical aspect. On the contrary to this, there is an no-boudary and floating organic architecture of integrated structure from ambiguous setting of relation between architecture and urban space in Ito's architecture. Especially, Mediatheque shows semantic integration of floating urban environmental factors through horizontal and vertical integration of horizontal slabs, vertical pipes, and skins. Last, horizontal and vertical factors of Wright' Housing is appreciated as an basic experienced structure in terms of spacial perception and fluidic inner spaces in Wright's housing is completed with a series of spatial experiences in a visual sense. On the other hand, no-boundary and floating space of Ito's architecture accept user's physical and virtual body. Especially, there is an integration transcending beyond time and space, accepting an imaginary body and events with the course of time at Ito's Mediatheque.

Although the Korea shipbuilding industry has recently been receiving most of the orders for ships in the world, production processes are being disrupted due to a shortage of manpower at the production site. This is because the workers quit the shipyard as both work and wages were reduced due to the long slump in the shipbuilding industry. The main reason for the increase in orders was the large-scale orders for Qatar LNG carriers, and the situation in which the technical specifications required for ships are becoming more complex is also working to an advantage. Because the contract delivery time is of utmost importance for ships, the dock launch plan is the most important management item among the shipyard's major processes. The structure to be built in the dock may be a hull that has left the design work or a finished vessel, and in some cases, it is often at the level of some blocks of the hull. When launching, the hull is affected by the hogging or sagging moment due to the fluid force, and securing the safety of the structural strength of the block connection is of utmost importance. In a normal process, the connecting member launches after welding has been completed, but in actual shipbuilders, quick decision-making is needed on the conditions for securing structural safety to comply with the docking schedule. In this study, a detailed analysis method and applicability using a bending stress evaluation method and finite element analysis modelling were analyzed to rationally judge the above-mentioned problems from an engineering point of view. The main contents mentioned in the thesis can be used as good examples when conducting similar structural strength evaluations in the future.
