This study analyzes the impact of import country environments on Korean fishery exports. To achieve the research objective, focusing on trade facilitation and import market aspects, the import country environment was modeled and analyzed by panel gravity analysis technique. In the basic export model considering only the trade facilitation aspect, agriculture and institutional factors had a significant impact on Korean fishery exports. However, when considering both trade facilitation and import market aspects, it was found that import market aspect had a greater influence on Korean fishery exports than trade facilitation aspect. Specifically, the import market factor that had the most positive impact on Korean fishery exports was the GDP of the import country. GDP, representing the economic scale of the country, indicates consumer purchasing power through per capita GDP. Hence, a higher GDP level implies a higher consumer purchasing power, suggesting a higher potential consumption of fishery products. The second positive factor influencing Korean fishery exports was food imports in the import country. Therefore, to expand Korean fishery exports, it is essential to target countries with high levels of GDP and food imports. Conversely, factors negatively affecting Korean fishery exports were merchandise imports and population in the import country. Therefore, countries with high levels of these negative factors should be managed as demarketing targets. Additionally, trade facilitation variables, which have relatively smaller influence, such as transparency and institutions, also significantly impact Korean fishery exports. While transparency has a positive effect, institution has a negative effect. Thus, to expand Korean fishery exports, strategies should focus on countries with high transparency and less stringent institutional regulations.

Purpose - The main purpose of this study is thus to investigate the contingent effect of imitation strategies on firm performance in transition economies such as China, focusing on pure and creative imitation. Design/methodology - We conducted a survey targeting department heads of each company who have more than 10 years work experiences. We assessed that the ability to gain trust and to access information from high-ranking informants would be greater if the firms were from the same country - Korea - as the lead researcher. A total of 200 highly reliable samples were obtained, which could effectively explain the nine variables set in the study. Relevant hypotheses were tested using a hierarchical linear model (HLM). Findings - The findings suggest that SMEs' technology level also had a positive impact on performance. Firms with better technology had a positive impact on performance, irrespective of pure or creative imitation. This reflects the cases where many Korean SMEs entering China without high technology level lose their competitiveness due to Chinese firms' technology catch-up within a short period of time. Originality/value - SMEs that lack technology and know-how need to focus on pure imitation strategies. It is possible that SMEs can perform creative imitation, but it seems difficult under the current circumstances. Therefore, SMEs with limitations in technology and know-how should maintain their competitive advantage for a while, by maintaining their pure imitation strategy.

One of the important areas of state policy in the socio-economic and cultural development of the country is cultural diplomacy. It contributes to the information dissemination about the country, strengthens interstate relations, and forms a positive image. Through cultural diplomacy, we achieve a positive perception of the world community of the country, determined by its place in the modern system of international relations. The aim of the study is a comparative analysis of cultural diplomacy opportunities for sustainable development at different levels of public relations, as well as the impact of cultural diplomacy opportunities on the indicators of the Global Sustainable Competitiveness Index and the Global Sustainable Development Index. Regarding the results of the research on the impact of cultural diplomacy opportunities on the indicators of the Global Index of Sustainable Competitiveness and the Global Index of Sustainable Development, four groups are identified among the countries of the European Union: countries with a very high level of sustainable competitiveness and sustainable development; countries with a high level of sustainable competitiveness and sustainable development; countries with low levels of sustainable competitiveness and sustainable development.

Clock selection has a significant impact on the performance and quality of designs in high-level synthesis. Almost systems require that the clock length is required prior to scheduling, the best value of the clock can be found only after evaluating different schedules. In this study, we presents a scheduling method that works simultaneously with synthesis by selecting a clock from a chainable operation set. Our scheduling algorithm is based on list scheduling and executes chaining considering bit level delays based on selected clock period. Experimental results show that our method improves the performance by 18 percent.

Purpose - This research aims to investigate the influence of social exclusion on conspicuous consumption. Specifically this research suggested that the influence of social exclusion on conspicuous consumption would be different depending on consumers' psychological characteristics such as internal attribution tendency and self-esteem. Design/methodology/approach - The experiment was conducted to verify hypotheses. 110 sample data were collected from the experiment and SPSS PROCESS Macro was used for data analysis. Findings - The result revealed that the interaction effect of social exclusion and internal attribution was significant. Specifically, social exclusion had on positive impact on conspicuous consumption for consumers with high level of internal attribution tendency. In addition, conspicuous consumption was pronounced for consumers having both high level of internal attribution and low level of self-esteem. Research implications or Originality - The result is expected to expand the research scope on social exclusion and conspicuous consumption, and provide practical implications for marketers.

This work focuses on finding out the noise source and the method of reducing the noise level of LPG(liquefied petroleum gas) fuel injector. The noise of LPG injector in operating condition is due to the impact between valve and valve seat. This study shows that if the revolution of engine is increased, the noise of LPG injector will be more serious but it is not nearly affected by the increment of fuel pressure. The source and transmission paths of noise are identified through the analysis of noise generation mechanism and noise spectrum. The sound absorbing material is tested to verify its efficiency of sound absorption thor the LPG injector. The effect of noise reduction of absorbing material is remarkable when the engine speed is high. Consequently two methods of reducing the noise level are suggested from the identified results. The one is to equip the absorbing material on the outer side of injector and the other is to coat with a soft material or equip a soft ring on the surface of impact.

The analog-to-digital-converter-based (ADC-based) backplane receivers that consist of a front-end ADC followed by a digital equalizer are gaining more popularity in recent years, as they support more sophisticated equalization required for high data rates, scale better with fabrication technology, and are more immune to PVT variations. Unfortunately, designing an ADC-based receiver that meets tight power and performance budgets of high-speed backplane link systems is non-trivial as both front-end ADC and digital equalizer can be power consuming and complex when running at high speed. This paper reviews the state of art designs for the front-end ADC and digital equalizers to suggest implementation choices that can achieve high speed while maintaining low power consumption and complexity. Design-space exploration using system-level models of the ADC-based receiver allows through analysis on the impact of design parameters, providing useful information in optimizing the power and performance of the receiver at the early stage of design. The system-level simulation results with newer device parameters reveal that, although the power consumption of the ADC-based receiver may not comparable to the receivers with analog equalizers yet, they will become more attractive as the fabrication technology continues to scale as power consumption of digital equalizer scales well with process.

Various seismic isolation and reduction devices have been applied to suppress the longitudinal vibration of continuous girder bridges. As representative devices, lead rubber bearing (LRB) and fluid viscous damper (FVD) might suffer from deterioration during the long-term service. This study aims to evaluate the impact of device deterioration on the seismic responses of continuous girder bridges and investigate the seismic behavior of deteriorated LRBs and FVDs. Seismic performance of a simplified bridge model was investigated, and the influence of device deterioration was evaluated by the coefficient of variation method. The contribution of LRB and FVD was assessed by the Sobol global sensitivity analysis method. Finally, the seismic behaviors of deteriorated LRBs and FVDs were discussed. The result shows that (i) the girder-pier relative displacement is the most sensitive to the changes in the deterioration level, (ii) the deterioration of FVD has a greater effect on the structural responses than that of LRB, (iii) FVD plays a major role in energy dissipation with a low degradation level while LRB is more essential in dissipating energy when suffering from high degradation level, (iv) the deteriorated devices are more likely to reach the ultimate state and thus be damaged.

The purpose of this study is to establish smart signage in a certain space and to analyze not only media ingestion and advertising inducement as well as any information (high vs. low vs. low) and flow level And the memory effect related to whether or not to remember. The results of this study show that the higher the interaction level and the higher the engagement level, the higher the advertising engagement is. In addition, media involvement was high when interaction level was low and flow level was high. Finally, if the level of interactivity is low and the level of flow is high, then non - valued attribution information is more likely to be recalled than the comprehensive evaluation information. If the interaction of smart signage is high and the flow of users is low, Recalled more recall information. In the future, detailed strategies for enhancing user flow will be needed rather than a strategy for unconditional enhancement of interaction in smart signage strategy.
