This study reveals that the user industry has a limited role as a source of technological capability in the case of the machine tools in Korea where the user industry is relatively mope advanced than other capital goods industry. The study examined the sources of technological capability in terms of migration of workforce and flow of product design information. Although the capital goods sector is generally regarded as being the sector where the user producer interaction is important the user industry failed to be the seed-bed of technological capability to develop machines. This study argues that this finding could have implications to the specificity of capital goods in a developing country.

This study was conducted to explore the nurse's perception of technological development and professional self-concept. The research subjects were 560 clinical nurses in Korea, who worked the general hospitals in Seoul, Kyeonggi, and the Kangwon province. Data sampling was done for the month, of December. 1997. The research tool consisted of 82 items questionnaires which were demographic data, TIQ, PSCNI. The research findings were as follows: 1. Nurses perceived the technological development as slightly positive (Mean =48.8). Also, nurses saw that the fastest developing technological nursing unit was the cardiac care unit, while the lowest technological developing nursing unit was the psychiatric unit. 2. The view of technological development was found to be significantly different according to religion (P=.0109), marital status (P=.0431), and the practical setting (P=.0048). Professional self concept was significantly different according to age (P=.0001), religion (P=.0001), education (P=.0007), marital status (P=.0000), career (P=.0001), and position (P=.0000). 3. The relationship between a nurse's perception of technological development and professional self-concept was highly correlated(r=.26, P=.0001). In the results of the multiple regression, the factors influencing professional self-concept were career, the nurse's perception of technological development, the level of technological development in nursing unit, and education. All these parameters showed the explaining power of 15.4% of the professional self-concept. In conclusion, nurses recognized the technological development was related to the professional self-concept. This study shed light on the meaning of technological development and vision of the nursing profession. Inservice education program should be developed to help the adaptability to technological development and conduct the qualitative research to explore the world of technological development which the nurses are experiencing in nursing.

This paper presents a new method for assessing the three-point-bending (3PB) strength of mortar beams in a non-destructive manner, based on neural network (NN) models. The models are based on the radial basis function (RBF) architecture and the fuzzy means algorithm is employed for training, in order to boost the prediction accuracy. Data for training the models were collected based on a series of experiments, where the cement mortar beams were subjected to various bending mechanical loads and the resulting pressure stimulated currents (PSCs) were recorded. The input variables to the NN models were then calculated by describing the PSC relaxation process through a generalization of Boltzmannn-Gibbs statistical physics, known as non-extensive statistical physics (NESP). The NN predictions were evaluated using k-fold cross-validation and new data that were kept independent from training; it can be seen that the proposed method can successfully form the basis of a non-destructive tool for assessing the bending strength. A comparison with a different NN architecture confirms the superiority of the proposed approach.

In SMEs, technological innovation is recognized as an important tool in terms of sustainable growth. This study analyzed the determinants of technological innovation by using the information of the corporate panel DB composed of local SMEs. The internal factors were added with technological innovation capacity and production capacity and the industrial cluster environment was first applied to external factors. Also, whether the industrial cluster environment influences technological innovation through R&D capabilities, the mediating effect was tested with the Sobel Test. Among the internal and external factors, the most important determinant was marketing ability, and a policy was proposed to develop measures to increase R&D capability with mediating effect. Among the technological innovation variables, which are dependent variables, the most determinant factor was the proportion of new product sales. For this, it is considered that additional research such as longitudinal research with the concept of repetition and parallax using the corporate panel DB is necessary.

지식기반 시대에서 IT제조기업 생존을 위한 기술혁신은 경쟁력 확보를 위한 필수요소가 되고 있다. 이러한 기술혁신은 다른 산업 영역보다 빠르게 변화하는 IT제조기업의 생존을 위해서는 더욱 필요하며 다양한 요인들이 기술혁신의 성공을 거두기 위해 필수적으로 고려되어야 한다. 본 논문에서는 IT제조기업의 기업 협력과 정부 지원이 기술혁신에 어떠한 영향을 미치는지 구조방정식(Structural Equation Model : SEM)을 이용하여 분석하였다. 그 결과, IT제조기업 협력과 정부의 지원은 기술혁신에 영향을 미치는 것으로 나타났다. 이는 정부의 IT제조기업에 대한 지원이 기업의 협력을 유도하고 보다 지속적인 관심과 육성이 필요함을 시사한다.

Nowadays, it is convenient to use 3D modeling tools for general planning before construction. Normally, a 3D model is built with 3D CAD such as 3D Studio Max, Maya, etc. or simply with AutoCAD. All these software packages are effective in building 3D models but difficult to use, because many provided functions and tools require prior knowledge to build both 2D and 3D designs. Moreover, the traditional method of building 3D models is most time-consuming as experienced operators and manual input are required. Therefore, how to minimize the building time of 3D models and provide easy-to-use functions for users who are not familiar with 3D modeling becomes important. In this paper, the VisualLISP programming language is used to create a convenient tool for efficient generation of 3D components for the AutoCAD environment. This tool will be demonstrated with the generation of a 3D sluice, an artificial passage for water fitted with a valve or gate to stop or regulate water flow. With the tool, users only need to enter the parameters of a sluice in the edit box and the 3D model will be automatically generated in a few seconds. By changing parameters in the edit box and pressing the "OK" button, a new 3D sluice model will be generated in a short while.

The paper establishes a policy classification system in order to classify and evaluate the science and technological innovation policies in Korea. We rebuild an innovation system model based on the national innovation system(NIS) concept. The model consists of human capital infrastructure(HCI), institutional infrastructure(II), technological infrastructure(TI), technology market(TM), industrial organization(IO), and innovation networks(IN). We give these 6 components of the modified system 1-digit number, respectively. Then we build the sub-systems according to these components, classify the policy categories in more detail, and finally complete the 3-digit policy classification table. This policy classification table may be useful in studying the science and technological innovation policy in both theoretical and empirical aspects. For example, the table can be the tool to examine the program portfolio profile(PPP) or to implement the questionary survey on the actual policies.

The objective of this investigation was to develop rules for automatic categorization of concrete quality using selected artificial intelligence methods based on machine learning. The range of tested materials included concrete containing a new waste material - solid residue from coal combustion in fluidized bed boilers (CFBC fly ash) used as additive. The rapid chloride permeability test - Nordtest Method BUILD 492 method was used for determining chloride ions penetration in concrete. Performed experimental tests on obtained chloride migration provided data for learning and testing of rules discovered by machine learning techniques. It has been found that machine learning is a tool which can be applied to determine concrete durability. The rules generated by computer programs AQ21 and WEKA using J48 algorithm provided means for adequate categorization of plain concrete and concrete modified with CFBC fly ash as materials of good and acceptable resistance to chloride penetration.
