  • Purpose: A multispectral algorithm for detection and differentiation of defective (defects on apple skin) and normal Red Delicious apples was developed from analysis of a series of hyperspectral line-scan images. Methods: A fast line-scan hyperspectral imaging system mounted on a conventional apple sorting machine was used to capture hyperspectral images of apples moving approximately 4 apples per second on a conveyor belt. The detection algorithm included an apple segmentation method and a threshold function, and was developed using three wavebands at 676 nm, 714 nm and 779 nm. The algorithm was executed on line-by-line image analysis, simulating online real-time line-scan imaging inspection during fruit processing. Results: The rapid multispectral algorithm detected over 95% of defective apples and 91% of normal apples investigated. Conclusions: The multispectral defect detection algorithm can potentially be used in commercial apple processing lines.

East Asian Maritime Security: Naval Power vs. Normative Power (동아시아 해양안보 : 해군력인가 해양법인가?)

  • The security environment surrounding the East Asian seas is rapidly changing due to the naval arms race among coastal states. The arms race is likely to worsen the security dilemma of the countries involved, thus increasing the chances for armed conflicts. It is too early to tell how the contemporary naval arms race in the region will evolve. But, for sure, the level of uncertainty is increasingly becoming high and intense. At the same time, there is emerging a legal warfare or lawfare among the rival countries. In particular, the United States and China have been involved in a serious debate about the nature and scope of the right of innocent passage and freedom of navigation in other countries' maritime zones. In collaboration with its regional allies, the United States has also put normative pressures on China with its excessive claims in the South China Sea. The latest arbitral tribunal case between the Philippines and China illustrates the point. With both arms race and normative competition in play, the future of East Asian maritime security will remain very complex and uncertain.

  • This study examined the comparative advantage of manmade textile (MMT) industries in the United States (US) and South Korea (SK). The Revealed Comparative Advantage (RCA) framework was used to assess the MMT industries' performance in both countries from 2004 to 2013. With the recent ratification of the United States-South Korea Free Trade Agreement (KORUS FTA), it is important to understand the current state of these industries. Using UN Comtrade export data, the RCA index values were calculated and analyzed for 27 MMT commodities, three aggregate groups, and the whole industry. It was found that SK had a consistent comparative advantage for the whole industry. Furthermore, SK had a larger number of products with a comparative advantage. The research findings indicate that the MMT industry in SK is likely to outperform the US following the complete ratification of the KORUS FTA.

  • This paper presents a summary of the state of the practice for Performance Based Seismic Design (PBSD) in the United States. While it is not included in the prescriptive provisions of the United States' building codes, the PBSD procedure has been successfully implemented for two decades. The recent publication of the Guidelines for Performance-Based Seismic Design of Tall Buildings by the Pacific Earthquake Engineering Research Center (PEER) illustrates the fact that the engineering community has embraced this procedure and provides a thoughtful set of recommendations to building designers who intend to implement PBSD. The key parameters currently required for a PBSD also are outlined, such as seismic hazard definition, modeling procedures, and acceptance criteria. These Guidelines will serve as the basis for many PBSD projects in the coming years and as such are a common reference used throughout this paper. Finally, a brief summation of recent PBSD projects in the United States is presented.

  • Over the past three decades, the impact of IT investments on firm performance has been the subject Q{active research. Although many studies have shown positive and significant benefits derived from IT investment, the findings of almost all these studies are based on data collected in developed countries. This study tries to investigate the effects of IT investment on firm financial performance in the Chinese electronics industry, a typical developing country, and compare it with the United States. Findings show that there is a positive impact of IT investment on firm performance in China. Moreover, the impact in China is not different from what occurred in the United States in the direction and the size against the assertion of previous studies and expectation.

  • In this paper, a conceptual model of legal culture based on Ehrlich's "living law" theory and Cole's social-cultural explanation can explain the low utilization rates of arbitration of Japan and the high utilization rates of arbitration in the United States, simultaneously. This model highlights the clash between social norms and legal provisions in Japan. Japan has developed a two-tiered system of dispute resolution. At the official level, Japanese people accept the legal system imposed by the outside world. But, at a deeper level, they utilize diverse forms of informal dispute resolution mechanisms, such as reconcilement and conciliation, reflecting their own social norms. In contrast, there is no conflict between social norms and legal provisions in United States. This study may show that there are distinctions between American-style arbitration and Japanese-style arbitration, reflecting their own respective social norms. The question of reconciliation between the American style of arbitration and the Japanese style of arbitration can be resolved by an international arbitrator.

  • The study investigated pre-service teachers' knowledge and computational skills by using Triangular Arithmagon. Participants included 90 pre-service teachers from two schools in the United States and Taiwan. The Triangular Arithmagons Test (TAT) was used to measure pre-service teachers' performance in whole number, fractions, and decimals operations (i.e., addition, subtraction, multiplication, and division), each of which included level-1 (basic) and level-2 (advanced) tests. MANOVA analysis was performed to compare the performance between teachers from the United States and Taiwan. Results indicated that overall, pre-service teachers in Taiwan outperformed those in the United States, especially on the advanced-level tests. Pre-service teachers in the United States were found to have poor ability of solving complex operation problems. Different curriculum plans and teaching methods may lead to the performance gap between the two countries.

  • In this digest, we briefly review our current molecular dynamics (MD) simulations that utilize both the reactive empirical bond order potential (REBO) and the adaptive intermolecular REBO (AIREBO) potential energy functions. The AIREBO potential includes intermolecular interactions, so that self·assembled monolayers, and liquids, can be modeled. We have examined the mechanical and tribological properties of model self assembled monolayers and amorphous carbon films. Self-assembled monolayers are modeled by covalently bonding hydrocarbon chains to diamond substrates. Because the REBO potentials can model chemical reactions, specific compression and sliding induced chemical reactions were identified.
