The number of new students at many domestic universities is declining. In particular, private universities, which are highly dependent on tuition, are experiencing a crisis of existence. Amid the declining school-age population, universities are striving to fill new students by improving the quality of education and increasing the student employment rate. Recently, there is an increasing number of cases of using the accumulated big data of universities to prepare measures to fill new students. A representative example of this is the analysis of factors that affect student employment. Existing employment-influencing factor analysis studies have applied quantitative models such as regression analysis to university big data. However, since the factors affecting employment differ by major, it is necessary to reflect this. In this paper, the factors affecting employment by major are analyzed using the data of University C and the decision tree model. In addition, based on the analysis results, a roadmap for student employment by major is recommended. As a result of the experiment, four decision tree models were constructed for each major, and factors affecting employment by major and roadmap were derived.

Software education is inevitable for the success of the Fourth Industrial Revolution, and university education also requires innovation to cope with revolutionary change of the society. The number of students seeking employment in the IT field is steadily increasing regardless of the major of the student. However, the existing software-related courses offered by universities or private educational institutions are limited. This paper analyzes the existing software curriculum of several major universities for non-IT major students. In addition, in-depth surveys by students at Seoul Theological University is conducted to figure out the demand for the advanced level computer science subjects. Finally, new software education curriculum is proposed to fulfill the needs of non-IT major students and to improve the employment rate of non-IT major students seeking tech companies. The new curriculum will help to cultivate intermediate level IT experts that bridge the gap between advanced level IT experts and primitive level computer technicians.

In Side of Supply and Demand of Fisheries Products, The Aquacultural Industry stayed in subsidized situation for the whole fishery industry of korea when it's dawned. But now a day, the Aquacultural Industry has been developed to unique industry itself, and it could be said the Hoe - korean style Sashimi or Sushi culture of korea can't exist without its aquacultural industry. So it could be said that the Aquacultural industry is not only a part of the fishery industry but also inevitable unique industry. The main objective of this paper is to analysis the present situation for production of Flatfish, distribution of Flatfish, and consumption structure of Flatfish. Especially, the production for aquacultural Flatfish in 2005 has been raised over 38 times against the production in 1990, and it takes the status as the major fish which leads the domestic aquacultural industry compare with others. The distribution of Flatfish can be divided to the domestic and export mainly. In field of its domestic distribution, Flatfish is the major item with Rockfish, and the deal of its over 90% happens in Similarity Fishery Wholesale Markets such as In-chon, Ha-nam, and Bu-san Fishery Wholesale Market not in the common distribution process of the fishery products. At present, the exporting of Flatfish take 13.9% among the whole Aquacultural Industry of korea, and Flatfish mainly export to Japan. Also, through the development of chinese economy, Hoe consumption culture is expanded gradually. And the future of exporting Flatfish is very bright because of developing of the U.S. market. The brief introduction of the consumption style of live fish is as belows. According to the research, generally the most of korean consumers prefer individual item as their food to combination style in korean Hoe consumption culture and the favorite item of korean consumers are Flatfish and Rockfish.

This study is conducted to investigate the factors affecting lumber conversion rate of sawmill industry in South Korea. Data were obtained from the survey of 38 sawmills in all geographic regions of South Korea. The variables examined in this study were region, softwood/hardwood log, domestic/imported/both log, the number of power-driven carriages (PDC) installed, the year when and country where PDCs was manufactured, the horse power of PDC, the number of labors required to operate each PDC, the sawing capacity of mill (mill size), and the types of major product and by-products. The lumber recovery factor (LRF) of sawmills were significantly influenced by the origin of logs, level of PDC automation, sawmill size, and size of logs (measured in diameter and length) while not by the location of the mill, types of major product and by-product, log species, and characteristics of PDC. Although these results provide useful information for understanding the technological characteristics of the Korean sawmill industry, further investigation with larger sample is necessary to reveal the more reliable characteristics of sawmill industry in South Korea.

In this study, we investigated anti-oxidative and anti-inflammatory efficacy, and identified their constituents from Brassica napus L. (Korean name: Yuchae) whole plant. Upon the anti-oxidative activities screening, the ethanol extract exhibited potent DPPH and ABTS⁺ radical scavenging activities. On the anti-inflammation studies using LPS-induced RAW264.7 cells, the extract inhibited the production of NO and pro-inflammatory cytokines (TNF-α, IL-1β, IL-6) effectively. To identify major constituents of B. napus extract, further purification was performed and led to isolation of two compounds; isorhamnetin 3,7-O-diglucoside(1) and isorhamnetin 3-O-glucoside(2). Quantitative analysis by high pressure liquid chromatography (HPLC) determined the flavonoid 1 as the major constituent. Isolated compounds showed DPPH radical scavenging effects and decreased NO levels without causing cell toxicities. These results indicate that the extract of Yuchae, a rich plant resource in Jeju Island, could be potentially applicable as an anti-oxidative and/or anti-inflammatory ingredients.
