Main theme of this paper is the evaluation of the historical significance of Luciano Baldessari's exhibition works mainly during the Fifties. In order to understand the formal and logical basis of those project, his relationship with the historical Avant-gardes and the consequences expressed in his pavilion projects for the Breda Industrial Company are analyzed. The first part focuses on the influence of Italian Futurism, German Expressionism and Italian Rationalism on the formation and experience of Baldessari during the interwar years. The encounter with these movements determine the interest but also the principles along which Baldessari represents his idea of object, space and place. Specially his professional activities during Fascism would determine his attitude toward political power and the necessity of autonomy in artistic sphere. In the second part, different themes that Baldessari affronted in each project of Breda Pavilions is analyzed. Another important issue regard the historiography of the contemporary architecture. Often, many important works that lies in the threshold of the disciplines such as painting and sculpture and media art were excluded in the history of architecture just because they do not deal with the architectural object. Recently, many elements such as theatrical project and temporary objects are considered as part of urban reality and architecture with acknowledgment of their capacity to create event and situations. Along this thought, not just the reconfiguration on the territory of architecture in present but also the criterion to evaluate the past history of architecture is changing drastically. This study on the pavilions of Baldessari intends to contribute indirectly on the current issue of dominion of architecture, but also to evaluate objectively recent architecture. Consequently, architectural protagonists such as Baldessari and their ephemeral projects would be evaluated compressively in their multiplicity of significance.

The mobile agent, which handles a given task while migrating between the sensor nodes, moves including the execution commands and task processing results. This increases the size of the mobile agent, causing the network to load, leading to the migration time delay and the loss of migration reliability. This paper presents the method of lightening the mobile agent using distributed object technology and the algorithm for exploring and providing the optimal migration path that is actively performed in the event of network traffic, and it proposes a method to ensure the reliability of the mobile agent migration by applying them. In addition, through the comparative analysis experiments based on agent size and network traffic for the migration time of mobile agent equipped with active rules in sensor network-based mobile agent middleware environment, applying the proposed methods proves to ensure the autonomy and migration reliability of the mobile agent.

Sandbox game users can double their satisfaction by re-creating a variety of play patterns. This creative process is due to the expansion of play through 'customizing' and 'action autonomy'. The purpose of this study is to investigate the structural limitations of freedom of online game. In a standalone game, the scalability due to the degree of freedom gives the user a strong motivation for world persistence. On the other hand, in online sandbox games such as MMORPG, it is confirmed that the goal-oriented tendency to gain advantage is the inherent limit of the freedom and expandability of the sandbox game. In this study, it is suggested that the cause and limit of growth of online-based sandbox game can be offset by the optimal solution factor.

As a hospital deals with people in their particular states, namely patients, computerization and automation in organization systems are very limited. Even though state-of-the-art medical systems such as the OCS, the HIS, the EMR, and the FACS are facilitating the computerization and informatization processes, they are for convenience and effectiveness. Ultimately, however, we should depend on specialists including doctors, nurses, pharmacists, and medical engineers. Therefore, a hospital is a representative labor-intensive body. Like other similar organizations, hospitals require a lot of manpower. But they are quite different in that hospital people hold variety and complexity in their qualifications and licenses. In personnel management, a hospital is twice controlled owing to the special characteristics that human life is at stake. First, the quota of medical manpower should be obeyed lest the quality of medical services should be lowered, and their roles and interrelations are even regulated. Second, in spite of the peculiarity of hospitals, the duties of obligatory employment and social insurances should not be neglected like other companies. In order that each hospital can preserve the proper level of medical services, securing the appropriate level of medical personnel has to be regulated. However, as the personnel cost is one of the important indices of hospital management, too much regulation in manpower supply can lead to poor hospital management and, in the end, the drop of the quality of medical services. In sum, as far as hospital personnel is concerned, some autonomy ought to be given to each hospital so that it can control the quality of hospital services. In addition to this minimum regulation of personnel, certain incentive and reward systems like the graded nursing system need to be prepared.

This study was conducted to determine the relationship between the job stress levels of 669 subway operators in Seoul after the installation of screen doors and their mental health. Data were collected using a structured questionnaire and via web site. A multiple linear regression analysis was conducted using the SPSS 20.0 statistical program. The total score of job stress turned to be higher than the standard score, and physical environment, job demand, insufficient job autonomy, interpersonal conflict and occupational climate were within the top 50% and organizational system within the top 25%. A correlation analysis revealed that job stress was positively correlated with all sub-domains of mental health. In terms of effects of job stress on mental health, there were significant differences according to job demand, organizational system, lack of reward and occupational climate, with an explanatory power of 36.6%. It is expected that this study can provide foundation for the establishment of organizational measures accustomed to job characteristics to prevent job stress of subway operators and the development and implementation of intervention programs for mental health promotion.

Recently, the United States and China have declared a 25% retaliatory tariff for the partner country products of 50 billion dollar scale. "Trade war" is getting full swing. Such conflicts between economic powers may spread to Japan like the domino phenomenon following the EU (European Union) and become bigger in the global trade war. As a result, Korea has an economic system with a high degree of external dependence, and there is an expert's analysis that it will become the largest victim of the global trade war. If the WTO Dispute Settlement Authority approves this US 301 retaliation measure in the same way as the past case (US-EU hormone-treated beef imports), the United States will not import any Chinese imported products Chinese products) can be imposed. If the US launches a special 301 or super 301, which is stronger than the regular 301, then China is very likely to enforce US retaliation against it, and the trade war between the two countries could become a reality. This phenomenon is likely to have a negative impact on Korean companies. In particular, Korea, which is highly reliant on intermediate goods exports to China, is expected to suffer a great deal of damage. Therefore, Korea needs flexible response at home and abroad, it is necessary to enhance the autonomy of companies and protect export industries. Adjusting corporate tax rate as well as domestic industry height will be one way. The long-term (21 months) trade war between the United States and China has resulted in economic uncertainty. The resulting damage must be compensated. It is necessary to prepare the compensation through the economic council between countries. In the future, the punitive damage compensation system should be introduced.

This paper is a part of "A Case Study on The Dwellings and Settlement of Korean Immigrants to North-Eastern Province of China". Among various subjects from the study, this paper covers with the spaces and life style in the dwellings of Korean Immigrants. The purpose of this paper is to discribe how their dwelling culture has been moved and changed to a new environment. One rural village of Korean Immigrants named "Ch'ang-ts'ai" in Yen-pien Province was selected where we investigated more than 110 households. From the formal interview, I collect the data on the family structure, family economic state, dwelling spaces and its use, and dwelling facillities and furniture. From informal interview with key informants, I analyze how they have changed their dwelling spaces and life style since they moved here. Based on the analysis of the data, I conclude that major features of their dwelling and life style has been moved from Korean penninsula, specially from 'Hamkyong' Province where their ancestor has lived. This features are summarized as follows: a. Dwelling spaces and its functions are simillar to typical dwelling type of Hamkyong Province. b. They use "Chong-ji" for both a cooking space and a major living space. c. They have a life style of sitting on the floor. d. Bedrooms are differentiated with male and female. e. Most of their dwelling facillities and furniture arc different from those of Chinese in the same province. Since they immigrated, there has been some social changes which could influence on making their dwelling culture. But they have preserved their cultural identity on their dwellings and life style. So I suggest that the dwelling culture of a society would be seldom changed by immigration, as long as they will be given similar conditions such as the independent ethnic community, the same ecosystem, and economical autonomy.

Position of surface objects can be fixed in many ways. The most popular radionavigational systems, including satellite systems, make possible obtaining nearly continuous and very precise ship's position. However, under the water application of radionavigational systems is impossible. Underwater navigation requires other tools and solutions then these encountered in surface and air navigation. In underwater environment vehicles and submarines, operate that have to possess alternative navigational systems. Underwater vehicles, in order to perform their tasks require accurate information about their own, current position. At present, they are equipped with inertial navigational systems (INS). Accuracy of INS is very high but in relatively short periods. Position error is directly proportional to time of working of the system. The basic feature of INS is its autonomy and passivity. This characteristic mainly decides that INS is broadly used on submarines and other underwater vehicles. However, due to previously mentioned shortcoming i.e. gradually increasing position error, periodical calibration of the system is necessary. The simplest calibration method is surface or nearly surface application of GPS system. Another solution, which does not require interruption of performed task and emergence on the surface, is application of comparative navigation technique. Information about surrounding environment of the ship, obtained e.g. by means sonic depth finder or board sonar, and comparing it with accessible pattern can be used in order to fix ship's position. The article presents a structure and a description of working of underwater vehicle navigation system simulator. The simulator works on the basis of comparative navigation methods which exploit in turn digital images of echograms and sonograms. The additional option of the simulator is ability to robust estimation of measurements. One can do it in order to increase accuracy of position fixed with comparative navigation methods application. The simulator can be a basis to build future underwater navigation system.
