The organic farming was begun with principles and values like environmental friendliness, symbiosis, and cooperation and circulation. And there has cut keen market competition, as sales and market size of organic agricultural products have been much larger. Thus producers and consumers have kept up with the market trend making light of the philosophy and principle of organic agriculture. So cases of fraud or false certification have been increased since 2010. Accordingly, not a few consumers have distrusted of the safety of organic agricultural products. And the status of organic agriculture has shown downward trend and market size of organic agricultural products has been reduced since 2012. Thus the income of organic agricultural farmers hasn't been increased. It is thought that present organic agriculture fell into the crisis. Now, organic agricultural farmers should practice farming methods based upon the philosophy and principle of organic agriculture in order to overcome its crisis.

Purpose: As one of the continuous studies on the offline distribution industry, the purpose of this study is to find ways for offline stores to respond to the growth of online shopping by identifying research trends on department stores. Research design, data and methodology: To this end, this study conducted word frequency analysis, word co-occurrence frequency analysis, BERTopic, LDA, and dynamic topic modeling using Python 3.7 on a total of 551 English abstracts searched with the keyword 'department store' in scienceON as of October 10, 2022. Results: The results of word frequency analysis and co-occurrence frequency analysis revealed that research related to department stores frequently focuses on factors such as customers, consumers, products, satisfaction, services, and quality. BERTopic and LDA analyses identified five topics, including 'store image,' with 'shopping information' showing relatively high interest, while 'sales systems' were observed to have relatively lower interest. Conclusions: Based on the results of this study, it was concluded that research related to department stores has so far been conducted in a limited scope, and it is insufficient to provide clues for department stores to secure competitiveness against online platforms. Therefore, it is suggested that additional research be conducted on topics such as the true role of department stores in the retail industry, consumer reinterpretation, customer value and lifetime value, department stores as future retail spaces, ethical management, and transparent ESG management.

U. N. Convention on Contracts for the International Sale of Goods (hereinafter the 'CISG' or the 'Convention') has been in force more than 37 years. The CISG responds to the need for uniform sales law. First of all, the biggest barrier against the uniformity in sales law is so-called "homeward trend". Professor Honnold, who served as secretary of UNCITRAL during the time in which the CISG was developed, pointed out the danger of "homeward trend" like this in his Article. "One threat to international uniformity in interpretation is a natural tendency to read the international text through the lenses of domestic law." CISG Article 79 is the principal provision governing the extent to which a party is exempt from liability for a failure to perform any of his obligations due to an impediment beyond his control. So-called 'Manfred Forberich' decision regarding the article 79 represents the most extreme example of what is likely the most dangerous error that tribunals applying the CISG can make. CISG Article 79 only governs impossibility of performance, and there is a controversy whether a disturbance which does not fully exclude performance, but it considerably more difficult or onerous(hardship, change of circumstances, economic impossibility) can be considered as an impediment. Unlike PICC and PECL, the CISG governs contract of sale. Therefore, events such as a sudden increase in the price of raw materials or a dramatic devaluation of currency, will not allow the seller to avoid his liability for non-delivery of the goods or to require renegotiation of the terms of the contract of sale. We should bear in mind that the CISG should be interpreted and applied in the context of the CISG itself.

The fashion market is expanding and competition is intensifying due to the contraction of consumption in response to the economic recession and changes in trends. In this study, design characteristics reflecting the brand identity and trend are analyzed as important factors for success. In this study, we will look at the design characteristics of knitwear among SPA brand products and help to plan knit designs. First, six brands were selected based on the sales and the number of stores in domestic and foreign SPA brands. The selected brands include UNIQLO, ZARA, H&M, SPAO, TOPTEN, and 8Seconds. We have selected weft knitting knitwear products(1,736 pieces), which are currently sold in domestic and foreign SPA brands, as silhouette items, knitwear design items, gauges, colors, patterns, images, and items as analysis items to analyze the causes of the differences in the design characteristics of domestic and foreign knitwear. The SPA brand has a wide range of tattoo floors, emphasizing practical aspects, a silhouette that fits the body, and a comfortable daily style. Domestic and foreign SPA brands did not show much difference, but Korean brands had a lower diversity of organization and used color for stable sales, showing a lower concern in trend and strong point color applications. If foreign brands pursue femininity based on a sexy image, Korean brands displayed a difference, emphasizing cute images. As for other design factors, it was found that brand identity was reflected more than domestically. As the cycle of trends becomes shorter, fast fashion is expected to continue in the future, and it is hoped that this research will be used as useful data for design projects of domestic companies.

Purpose: Compared to the rapid growth rate of the domestic automotive LED industry so far, the predictive analysis method for demand forecasting or market outlook was insufficient. Accordingly, product characteristics are analyzed through the life trend of LEDs for automotive exterior lamps and the relative strengths of p and q using the Bass model. Also, future demands are predicted. Methods: We used sales data of a leading company in domestic market of automotive LEDs. Considering the autocorrelation error term of this data, parameters m, p, and q were estimated through the modified estimation method of OLS and the NLS(Nonlinear Least Squares) method, and the optimal method was selected by comparing prediction error performance such as RMSE. Future annual demands and cumulative demands were predicted through the growth curve obtained from Bass-NLS model. In addition, various nonlinear growth curve models were applied to the data to compare the Bass-NLS model with potential market demand, and an optimal model was derived. Results: From the analysis, the parameter estimation results by Bass-NLS obtained m=1338.13, p=0.0026, q=0.3003. If the current trend continues, domestic automotive LED market is predicted to reach its maximum peak in 2021 and the maximum demand is $102.23M. Potential market demand was $1338.13M. In the nonlinear growth curve model analysis, the Gompertz model was selected as the optimal model, and the potential market size was $2864.018M. Conclusion: It is expected that the Bass-NLS method will be applied to LED sales data for automotive to find out the characteristics of the relative strength of q/p of products and to be used to predict current demand and future cumulative demand.

Korea's domestic construction market and overseas construction order environment are experiencing a decreasing trend, and this trend is expected to continue. Therefore, domestic construction companies are seeking to enter the global construction market. This study analyzes the global construction market and the global competitiveness for global construction companies and provides the results. To this end, this study has developed a model to evaluate the global construction competitiveness level and to evaluated global construction competitiveness in 2016. The evaluation of global construction competitiveness was analyzed based on the competitiveness of construction infrastructure by country, and the evaluation results of competitiveness of construction companies. These assessments were based on 20 detailed international statistics (ENR, Global Insight, Compass, etc.). The evaluation results are as follows. First, in regard to the comprehensive global construction competitiveness by country, America ranked first among 20 countries, followed by China. European countries like Spain, Germany and the Netherlands ranked third to fifth, respectively. Korea ranked sixth, one rank higher than that of the previous year. America and European countries remain strong. Second, in regard to the comprehensive building infrastructure competitiveness by country, America ranked first followed by Germany. Korea ranked twelfth, which is the same rank as that of the previous year. When it comes to stability in the construction market, China ranked first and Korea eighth. For construction systems, Sweden ranked first and Korea thirteenth, and for infrastructure, Japan ranked first and Korea tenth. Third, according to the construction company's capability evaluation by country, America ranked first followed by China. Korea ranked fourth, two ranks higher than that of the previous year because of its building competitiveness (fifth → fourth) and design competitiveness (eleventh → eighth) which has improved. When it comes to building competitiveness, China ranked first and Korea fourth. For design competitiveness, America ranked first and Korea eighth, and for price competitiveness, India ranked first and Korea seventh. However, Korea is still in the middle of the pack rank among the 20 countries considered when it comes to design competitiveness. It is ranked eleventh for design productivity and thirteenth for foreign sales against the total sales (internationalization). Thus, Korea needs to improve technical power and tap into new markets for improved competitiveness, including increased productivity. To do so, more R&D investment is required.
