Recently, the interdisciplinary linkage between engineering and social science has received an increasing attention as an emerging education discipline. Due to intrinsic complexity of innovation process and heterogeneity of disciplinary nature, however there exists little, if not no, effort to draw a common framework in terms of educational scope and contents of the new subject. This paper presents a number of criteria and guidelines for building up new educational framework by integrating engineering subject and social science subject. Specifically, three neo-disciplines, technology policy, technology management, and economics of technology are considered since it is postulated that the forementioned disciplines have established academic identity and fundamental structure By nature, this paper is an exploratory and seminal one. It is not the purpose of this paper to provide a concrete table of contents of educational material. Instead, it merely brings up a discussion topic for the wide audience of academic arena, leaving the gradual consensus and convergence as future task.

We are in the process of developing information systems that can be helpful for the effective management of community health services provided by the health center and subcenters in Hwachon Gun, Kangwon Do. In doing so, we have employed a different program design from those programs of information systems developed in other health centers or subcenters. The main idea of our design is dividing all the programs into two parts. One part is for the control of operation functions such as addding, seeking, editing, and printing needed to all the tasks. The other consists of a set of programs each of which deals with a specific task. It is believed that this program design would result in an information system that is simple to use, easy to modify and expand, and flexible to new computer technologies.

The Korean railroad has developed as a foundation of nation's nucleus network. Nowadays Korea has entered into a new era because of the operation of KTX(Korea Train Express). As an introduction of KTX, the Korean railroad system has advanced Korean style high speed rail(HSR-350x), which is based on transfer and own technology. It is expected that the Korean rail road system has the leading design and production ability. Korea is planning to develop its own high speed railroad system until 2007. So the present task is to initiate a strategic export method for the development and value-added of Korean high speed railroad system. Furthermore this study proposes the administrative and technical policy for the basic technical research and creativeness predominance.

The purpose of this study is to empirically investigate the determinants of occupational commitment of hospital nurses. For this study, a causal model of occupational commitment of hospital nurses was constructed based on the exchange theory. The sample of this study consisted of 329 nurses from S general hospitals located in Seoul and south-eastern area of Korea. Data were collected with self-administered questionnaires and analyzed using hierarchical multiple regression. It was found that four task reward variables(variety, significance, workload and resource inadequacy), one social reward variable(supervisory support) and two organizational reward variables(promotional chances and pay) had significant net effect on hospital nurses' occupational commitment. The implications of these findings were discussed and the suggestions for future research wert advanced.

The study of public health systems is an important, but very difficult task. The concept and functions of public health systems are influenced by the views, interests, and influence of the various stakeholders belonging to public health systems and broader social, economic, political, and environmental sectors. To define public health system with conceptual clarification, we must take into account the dynamic and complex aspect of the public health system. This paper reviews health systems and public health systems literature to suggest the concept, goals, and functions of public health systems. In addition, this paper recognizes some challenges, such as leadership and management, resource development, economic support, and service delivery to strengthen public health systems for improving health and well-being of population.

The existing PKI authentication structure uses the OCSP method. The primary task of OCSP is to verify the status of a transaction after verifying the validity of the certificate; but, because of continuing policy changes and updates within the PKI authentication method, the status of certificates and the structures are not consistent. Therefore, the SCVP method can be selected as the broadest method for completing authentication tasks accurately because the SCVP method includes validation of policy changes. An appropriate method for building an mobile environment within the capabilities of low-memory and reduced processing CPU needs to be assessed and developed. This thesis proposes a verification method that is independent of platform and applicable to any 05 in building and expanding the mobile environment.

This paper analyzes how IT adoption affects differently on the shippers' make-buy decision, depending on the changes through agency and coordination problems. Empirical findings are consistent with the theoretical predictions on the changes of shippers' decision, summarized as follows. First, while the adoption of agency-cost reducing IT leads to the increase in the proportion of private fleets, the adoption of coordination-cost reducing IT leads to the increase in proportion of for-hire carriage. Second, the extent of private fleets changes depends on the primary product type that trucks load, with products of important service task experiencing more increase. Third, the extent of for-hire carriage changes depends on the truck's trip distance, with long-trip trucks experiencing more increase. With the results, we present different policy implications from the conventionally advocated ones.

Utilizing outside knowledge for innovation is an important task for companies in the competitive economy. Due to the rapid advance in the internet communication technology, the number and quality of innovation sourcing methods are increasing. We select co-creation, personalization and in-house R&D as the representative forms of innovation sourcing and suggest a game theory model that enables the comparative analysis between them. The decision and surplus outcome of the innovation mechanisms are compared under various settings of the input parameters of the model. The stakeholders voluntarily participate into all mechanisms when the product price is moderately high and the participation cost is low, while co-creation is the only feasible one when the product quality is niche. When the participation cost is relatively high, personalization outperforms co-creation.

Autonomous radiation source detection has long been studied for radiation emergencies. Compared to conventional data-driven or path planning methods, deep reinforcement learning shows a strong capacity in source detection while still lacking the generalized ability to the geometry in unknown environments. In this work, the detection task is decomposed into two subtasks: exploration and localization. A hierarchical control policy (HC) is proposed to perform the subtasks at different stages. The low-level controller learns how to execute the individual subtasks by deep reinforcement learning, and the high-level controller determines which subtasks should be executed at the current stage. In experimental tests under different geometrical conditions, HC achieves the best performance among the autonomous decision policies. The robustness and generalized ability of the hierarchy have been demonstrated.

With the ready access to the high resolution satellite image data, users of and areas covered by satellite image data are constantly on the rise world-wide. Korea will also be able to take full advantage of the satellite data once the KOMPSAT is successfully launched. Harmonizing satellite data production and application technology and users' needs, along with the guiding policy is essential for promoting satellite data use. Up to now, the Korean government has mainly concentrated on developing production technology for the satellite units. However, the imminent task of independent satellite data production demands a promotion policy for satellite data use. In this context, the policy is defined as an important medium for identifying the role and status of satellite image information at the national level and also Preparing the legal as well as systematic foundation for producing, building, distributing, and packaging satellite data. For example, in the countries with the advanced satellite technology, such as the United States, the United Kingdom, and Australia, digital ortho image and digital elevation model (DEM) are mandatorily included in the National Geographic Framework Data through policy measures. In addition, in order for the efficient provision of the satellite data, separate organization or agency is being in operation for the exclusive production and distribution of the satellite data. The present paper aims to examine the role and status of the satellite data as well as their current status and problems in Korea in reference to the National Spatial Data Infrastructure, and finally to provide the policy directions to promote the satellite data use in public sector on the basis of the preceding analyses.
