This study aims to investigate the current status of science museum in terms of evaluating its organization, management, and education program. The analytical framework developed for examination are as follows: First, the lack of professional staff in most target museums is the biggest impediment for domestic science museums to function properly. Second, funding has been very poor. Third, most museums failed to properly sustain exhibits, equipment, and facilities. Fourth, various advertising and marketing efforts for attracting more visitors are hardly done. And lastly, the domestic museums made little effort in pursuing research focusing on improving exhibitions and education program. Based on these findings, the future directions for domestic science museums to step-up opportunities have been discussed in this study.

Competitiveness of service industry in Korea is relatively lower than OECD countries'. Korean government, therefore, has been trying to improve the competitiveness of service industry by accelerating information technology (IT) adoption. Even though most of factors of IT can be contributed to improve the financial performance, it may be affected differently among various industry types and life cycles of companies. Therefore, it is one of very important research issues to analyze the influential effect of IT considering industry types and organizational life cycles in service industries. The purpose of this study is to find out critical success factors of IT which influence financial performance considering different types and life cycles of service industries. We developed the model and identified key success factors of IT adoption as IT system quality, Information quality, IT maintenance, CEO support, IT education of organization, and IT competence of user. Additional analysis of moderating effect by organizational life-cycle and types of service industry are conducted. For data sampling 856 companies are participated and total 2,000 questionnaires are collected. Structural equation modeling method is conducted for statistical analysis. The results show that the model is valid and most of success factors of it are very useful for improving financial performance of service industries except organizational IT education. Moderating effect of industry types and organizational life cycles is valid but partially accepted. The results might be able to provide useful directions and guide lines of IT acceleration in service industries.

We perform the frequency-domain waveform inversion based on the residual-selection strategy. In the residual-selection strategy, we classify time-domain residual wavefields into several groups according to the order of absolute amplitudes. Because the residual wavefields are normalized after regularization of the gradient directions within each group, the residual-selection strategy plays a role in enhancing the small-amplitude wavefields, which contributes to improving the deep parts of inverted subsurface images. After classifying residuals in the time domain, they are transformed to the frequency domain. Waveform inversion is performed in the frequency domain using the back-propagation technique which has been popularly used in reverse-time migration. The residual-selection strategy is applied to the SEG/EAGE salt and IFP Marmousi models. Numerical results show that the residual-selection strategy yields better results than the conventional frequency-domain waveform inversion.

In urban regeneration, resident participation and respect of residents' need have become a major important issue. The purpose of this study is to identify residential area improvement characteristics expected by local residents. Data used for this study were collected from survey which used questionnaire and village image map construction tool kit, developed for facilitating the residents' participation in an actual housing improvement area at Kwngjoo, Korea. The major contents surveyed through questionnaire were first, future images of the area second, directions of improvement third, preferred architectural types such as high or low rise buildings. and a total of 335 data was collected within 4 days during 12-14 December, 2008. The kit was used by parents of students at a local elementary school, and 205 image maps were collected. Content analysis was to analyse characteristics of villages shown in the constructed image maps. Lynch's five elements were utilized to select areas for analysis. As a result, types of buildings desired by residents at the selected four local areas were identified. In general, residents desired their village to be improved with low and mid rise buildings, respecting existing cultural assets. This study showed that there is certain characteristics in relation to the selected areas. Besides, the tool kit used this study showed the effectiveness in collecting opinions from young households in the improvement area within a short time. The tool is expected to be useful in attracting residents and in facilitating participation of wide range of local residents by improving the constraints stemming from time and space.

A deterministic stress-based methodology has traditionally been applied in pipeline design. Meanwhile, reliability based design and assessment (RBDA) methodology has been extensively applied in offshore or nuclear structures. Lately, the release of ISO standard on reliability based limit state methods for pipelines ISO16708 indicates that the RBDA methodology is one of the newest directions of natural gas pipeline design method. This paper presents a case study of the RBDA procedure for predicting the time-dependent failure probability of pipelines with corrosion defects, where separable Monte Carlo (SMC) method is applied in the reliability estimation for corroded pipeline instead of traditional, crude Monte Carlo(CMC) Method. The result shows the SMC method take advantage of improving accuracy in reliability calculation.

Despite the importance of customer satisfaction corresponding to the phenomenal development of the gas industries, supplier-centered management still prevails in the city gas industry due to the monopolistic market environment. However, customer's demands for diverse and higher services are ever growing in the midst of the development and the accelerated competition of the service industries. In this context, customer satisfaction management may be the best style of management for establishing a short, mid and long-term foundation of growth. This paper derives directions for improving customer satisfaction management in such 3 areas as systematic, technological and service improvement from the environmental changes as well as from the customer needs. Based on the survey and comparative analysis of customer satisfaction, we also suggest 5 growth strategies to maintain sustainable development of the gas industry in the midst of competitive environment between city gas companies and among diversified energy businesses and to protect rights of the city gas consumers.

In Korea, fish is a major food source, and sustainable production of fish is critical for the aquaculture industry. Recently, infectious diseases have become an unavoidable problem in aquaculture and have caused serious economic losses. Therefore, there is an urgent need to overcome this challenge to increase productivity in aquaculture. Vaccination is the most effective and long-term measure for improving the management of a fish farm. Sales of fish vaccines in Korea have been steadily increasing, with a confirmed increase from 600 million won in 2007 to 3.4 billion won in 2018. As of 2021, 30 licensed fish vaccines, including both single and combination vaccines containing more than two inactivated pathogens, have been approved in Korea for 10 fish pathogens. Twenty-eight of these are used in olive flounder Paralichthys olivaceus; however, only two vaccines are used in starry flounder Platichthys stellatus, red seabream Ragrus major and rock bream Oplegnathus fasciatus. Therefore, vaccine development is required not only for the olive flounder but also for other cultured fish species. The development of effective vaccines and vaccination programs for fish is a continuous requirement for a sustainable aquaculture industry.
