This study compares various transformation techniques for multifocus image fusion. Multi-focus image fusion is a procedure of merging multiple images captured at unalike focus distances to produce a single composite image with improved sharpness and clarity. In this research, the purpose is to compare different popular frequency domain approaches for multi-focus image fusion, such as Discrete Wavelet Transforms (DWT), Stationary Wavelet Transforms (SWT), DCT-based Laplacian Pyramid (DCT-LP), Discrete Cosine Harmonic Wavelet Transform (DC-HWT), and Dual-Tree Complex Wavelet Transform (DT-CWT). The objective is to increase the understanding of these transformation techniques and how they can be utilized in conjunction with one another. The analysis will evaluate the 10 most crucial parameters and highlight the unique features of each method. The results will help determine which transformation technique is the best for multi-focus image fusion applications. Based on the visual and statistical analysis, it is suggested that the DCT-LP is the most appropriate technique, but the results also provide valuable insights into choosing the right approach.

The main target to do this analysis is to find out the competitiveness between 2 countries(Korea and USA) in the ship business industry. Ever since free from Japanese empire domination of modern history in Korean peninsular, Korea has been strong relationship with USA almost every fields. The purpose of this research is to realize which country is more competitive between 2 country's trade structure. This research conducted for period from 2000 to 2016. Expecting effect is to learn how to improve ship industry for 2 countries. Research method is used by comparative advantage trade theory. Even though Koran government has been accomplishing trade stimulus environment against USA ship industry, it is research limitation that overseas productions both Korean & USA are not available due to company business strategy. From early 50's, every USA industries hold a dominant position so far. Now, Korea is comparative advantage against that of USA in the field of ship industry. Sound competition relationship is good for both 2 countries for mutual benefits. The future prospect is Korea needs export market diversification to enlarge economic growth in the long run.

This study describes the seller's duty to deliver the goods in conformity with the contract. The purpose of this study is twofold: to analyze the seller's principal duty, comparing the United Nations Convention on the International Sale of Goods(CISG) with Sale of Goods Act(SGA) and to provide legal and practical advice to contracting parties who consider CISG or SGA as a governing law. This paper first considers the requirements for the conformity with the contract, which means contractual requirements agreed between parties and implied requirements not agreed between parties. Following this, the exclusion of the seller's duty to deliver the goods required by the contract is described. Finally, this paper ends up giving contracting parties legal and practical advice.

Purpose - This study, in seeking to understand the trade structure of both Korea and China, aims to strengthen Korea-China economic cooperation; it examines trade impediments by analyzing the problems affecting trade and addressing these problems, thereby discovering ways to expand trade between these countries. Research Design, Data, and Methodology - The index of trade intensity developed by the trade intensity theory (Kruger, 1997) is used to analyze the trade decision factors of both countries. Although specific factors should have materialized from the analysis of trade decision factors, determining concrete explanations is difficult in reality, as there are many unsolved and diverse factors. Results - First, the index of A value/B value is the index of Korean versus Chinese market share/Korean versus world market share, which is a measure of comparative market intensity. Second, Korea has a comparative advantage in export specialization and, conversely, China has a comparative advantage in import specialization. Third, compared to 2000, the revealed comparative advantage (RCA) indexes are considerably improved. Conclusions - This study used quantitative measurement for analysis, applying trade intensity theory, trade specialization, and RCA indexes to gauge how inter-trade relations have changed between Korea and China during the past 10 years (2000, 2005, and 2012).

Increasing the vertical dimesion affects not only functional problems but also the facial appearance. In particular, when restoring the reduced vertical dimension, it is important to evaluate facial appearance because the change affects the patient's aesthetics. Cephalometric radiographs can predict changes in the facial appearance through skeletal and vertical classifications using anatomical indicators, and the changes before and after treatment can be easily observed, which could serve as good data in evaluating treatment success. In this study, comparative evaluation was performed through cephalometric radiography, and the aesthetic and functional improvement was confirmed.

This study investigates the conditions under which the compensation effect occurs in advertising, focusing on the influence of warmth messages on consumer perceptions and responses. By comparing single-ad and comparative ad exposure contexts, the research reveals how warmth messages affect perceived brand competence and the intention to like ads. High warmth messages, when viewed in a comparative ad setting, lead to lower perceived brand competence compared to a single-ad setting, emphasizing the need for strategic message placement in competitive environments. The study further explores how consumers' construal levels-whether considering near-future or distant-future purchase decisions-moderate these effects. The negative impact of high warmth messages on perceived competence is amplified in a comparative context at low construal levels, while high construal levels mitigate this negative impact. These results provide both theoretical and practical insights, highlighting the importance of ad context and construal level in advertising strategies.

The purpose of this comparative study is to compare and evaluate international arbitration and forum selection agreements. Recent decades have seen an unparalleled expansion of global trade and investment. Business enterprises of every description ann find themselves entangled in legal proceedings with foreign companies or government entities. Thus, the costs of these proceedings and the consequences of losing are often substantial. Almost, every international commercial controversy poses a critical preliminary question - 'where, and by whom, will this dispute be decided?' the answer to this question often decisively affects a dispute's eventual outcome. It can mean the difference between winning and losing. between de minimis damages and a multimillion dollar award. The same dispute can have materially different outcomes in different forums. Because of the importance of forum selection, parties to international contracts often include contractual dispute resolution provisions in their agreements. These provisions significantly reduce the uncertainties inherent in international commercial disputes, and can offer a substantial measure of partisan advantage. as a consequence, it is almost always advisable to include a contractual dispute resolution provision in any international contract. These provisions typically take the form of : (1) forum selection clauses, or (2) arbitration agreements.
