This study determines whether or not firms can achieve high productivity growth through external technology acquisition. It also identifies the key factors affecting adopting firms' productivity growth by employing the Malmquist productivity index (MPI) methodology, which features computational ease, low data dependency, and decomposition of productivity growth into technical efficiency change and technical change. Results showed that the effects of productivity growth arising from technology transfer became stronger over time. Moreover, patent transfer guaranteed firms' productivity growth, but no evidence was found that factors such as age and size could increase productivity. Finally, cultural similarity could be another factor conditioning the effectiveness of technology transfer in the productivity of adopting firms.

This study was done in order to increase production speed using coater dryer in maximum capacity without print mottle. The aim of this study was to measure coating color immobilization content(CCIC) and to decrease CCIC through coating color optimization. The final goal of this study was the prevention of print mottle in maximum drying condition by CCIC control. As a result the measuring method of CCIC was set by brightness transition and the effective factors in pigments and binders were defined. With color optimization considered this factors, CCIC was decreased by 4%. Through this CCIC decrease and modification of coater utility, the print mottle was prevented even though using coater dryer in maximum.

In order to investigate the influencing factors in flotation fractionation, flotations were performed at varied conditions. The selectivity of fines fractionation was mainly affected by long fiber flocculation degree and if there were not sufficient flocculation of long fibers, more loss of long fibers could not be avoided. The amount of flotation rejects were totally dependent on the stability of froth floated on the stock surface. Only small size fines could stabilize the froth as they hindered the drainage of liquid lamella in flotation-froth. More flotation reject and better flocculation of long fibers were two important factors for improving flotation. Changing a flotation flux or an air-mixing ratio to increase the flocculation of fibers increased long fiber ratio in the reject. In order to satisfy the both conditions of reducing long fiber loss and of increasing flotation reject, search of fractionation promoter is needed.

The idia of modern product design is translated from the concept of functional importance as the basic function to that of emotional importance as the supplement function. In other words, the interests of the emotion in human performance side based on psychological factors of human are increased as well as the function in technical performance side based on physical factors of product. The standard emotional works for understanding the human's emotion are arranged in this paper. The standard emotional words are composed of words expressing the humaa's emotion. The adjectives adaptable to human's emotional works are collected from Korean dictionaries and arranged in the semantic differential(SD) scale. Next, the words with great marks evaluated by SD method are analyzed by factor analysis(FA) method and characterized as emotional words for understanding the human's emotion. The standard emotional words arranged in this paper are important because they are basic information for the development of product or technology as well as for the matter of emotional measurement technical development.

This study aims to identify the relations between seakeeping characteristics and hull form parameters for YTU Gulet series with cruiser stern. Seakeeping analyses are carried out by means of a computer software which is based on the strip theory and statistical short term response prediction method. Multiple regression analysis is used for numerical assessment through a computer software. RMS heave-pitch motions and absolute vertical accelerations on passenger saloon for Sea State 3 at head waves are investigated for this purpose. It is well known that while ship weight and the ratios of main dimensions are the primary factors on ship motions, other hull form parameters ($C_P$, $C_{WP}$, $C_{VP}$, etc.) are the secondary factors. In this study, to have an idea of geometric properties on ship motions of gulets three different regression models are developed. The obtained outcomes provide practical predictions of seakeeping behavior of gulets with a high level of accuracy that would be useful during the concept design stage.

Purpose As information management grows in importance around the world, organizations are investing in information security technology. However, the higher the level of information security technology in an organization, the higher the techno-stress of employees. The purpose of this study is to suggest stress factors related to information security technology that affect the reduction of employees' intention to comply with information security and to suggest ways to alleviate stress. Design/methodology/approach The research presented a model for mitigating technical stress related to information security based on technical stress theory and person-organization fit theory. 346 questionnaire data were analyzed from the members of the organization who applied the information security technology, and the research hypothesis was verified through the structural equation modeling. Findings The hypothesis test confirms that security-related techno-stress reduces the information security compliance intention of employees, organizational technical support mitigates technical stress, and person-organization fitness mitigates the negative relationship between techno-stress and compliance intention. The results of the study contribute to the organization's strategy for minimizing the reduction of the information security compliance intention of employees, and are meaningful in that the theoretical basis for mitigating techno-stress is provided in the field of information security.
