This study was carried out to investigate the effects of gamma irradiation for the improvement of hygienic quality and the extension of shelf-life of Kwamegi(semi-dried colobabis seira). Kwamegi was stored at $5^{\circ}C$ and $15^{\circ}C$ after gamma irradiation with doses of 0, 3, 5, 7 and 10 kGy. In microbiological aspects, non-irradiated Kwamegi was rapidly deteriorated during storage, and some harmful bacteria were detected in a microbial analysis using a selective medium. However, the total viable cells and presumptive pathogens were reduced with the increase of irradiation dose, and dose level of 7 to 10 kGy was considered to be optimum and effective dose for the preservation of Kwamegi.

There are some considerations that must take into account in environmental education in the aspect of the difference of value clarification between ecological and economic viewpoint on environment. Although we have a tendency to think that the differences are unavoidable because we are on the economy-oriented life, we should realize that such emphasis to economics comes from the differences between ecological and economic view point on environment. We have lived and thought on the basis of Economic view point, especially, environmental policies are established on the basis of economic efficiency. But this tendency has become great obstacles to environmental ethics education because it dilutes the reason of natural preservation and removes the fundamental reasons why the nature should be preserved. Therefore it is very difficult to balance the value clarification between economic and ecological viewpoint in actual life. Furthermore, environmental problems can not be solved only through economic approach, because of their limits to belief solving from providing incentives. It is very important to make people have a way of thinking which economic activities and debates can be made on the ecological resources. Therefore we can compare this relation to CHAE-YONG founded on Buddism and Chinese philosophy. CHAE means essence of every reaction in the cosmos, and YONG means the reaction itself. CHAE is regarded to ecological resources, and YONG is thought to every-day economic activities. YONG is not able to existwithout CHAE. If economic activities can be done on the basic limit of ecological resources, we can build suitable environment to living condition. We call this appropriate environment as SANG. In other words, the connection of CHAE-YONG-SANG means ecological resources - economic activities - sustainable environment. It is realized that the relations between economics and ecology should be equalized for the balanced environmental ethics education. This study tries to get out of unbalanced relations between economics and ecology from the persepectives of CHAE-YONG-SANG and it was done to suggest an alternative environmental ethics education program

The evaluation of package temperature for fresh preservation of cucumber was investigated. The fresh cucumber is available in markets of Korea during whole seasons, for the help of farmer, distributor and consumer. Cucumbers were stored within cardboard boxes packaging covered with low density polyethylene (LDPE) at different temperatures (5, 10, 15 and 20℃). Changes in weight loss, hue angle, firmness, moisture content and general appearance (shape of cucumber) were investigated during storage of cucumbers. General appearance index with non-packaging decreased more than with LDPE film packaging at 5℃ and 10℃. During storage of cucumbers, general appearance index as freshness showed packaging effect at low temperature than room temperature. In the fresh weight loss, the packaged cucumbers were less reduced than that of the non-packaging ones. At color change, Hue angle of cucumber stored within low temperature with film packaging decreased gradually during storage. However remarkable change in hue angle were observed in cucumber within LDPE film packaging treatments of 15℃ and 20℃ storage. The effect of hue angle with packaging appears differently depending on the storage temperature conditions. The firmness and moisture content of cucumber flesh were not affected by packaging and storage temperature. In this experiment, cucumbers packaged with LDPE film at 5℃ and 10℃ were the most desirable for extending the quality. These results suggest that packaging of low temperature treatments in combination could be effective in prolonging the shelf life of cucumber.

In accordance with the revision of the Data 3 Act, such as the Personal Information Protection Act, it is possible to process pseudonym information without the consent of the information subject for statistical creation, scientific research, and preservation of public records, and unlike personal information, it is legal for personal information leakage notification and personal information destruction There are exceptions. It is necessary to revise the pseudonym information in that the standard for the pseudonym processing differs by country and the identification guidelines and anonymization are identified in the guidelines for non-identification of personal information in Korea. In this paper, we focus on the use of personal information in accordance with the 4th Industrial Revolution, examine the concept of pseudonym information for safe use of newly introduced pseudonym information, and generate / use / provide / destroy domestic and foreign non-identification measures standards and pseudonym information. At this stage, through the review of the main contents of the law or the enforcement ordinance (draft), I would like to make suggestions on future management / technical protection measures.

This study explored how simultaneous treatment of monoammonium phosphate (MAP) and boric acid for Pinus densiflora and Populus euramericana influenced the properties such as fire resistance, preservation against Trametes versicolor and Tyromyces palustris, and compressive strength of the treated woods. For specific gravity and compressive strength, the treated woods were higher than the non-treated ones. For the analytical features observed by SEM, the cell walls of the non-treated woods were extremely destructed by T. palustris and T. versicolor while the treated ones relatively remained intact. Especially, P euramericana was more readily exposed to the attack of the rot fungi than P. densiflora.

Mongolian horses are one of the oldest horse breeds, and are very important livestock in Mongolia as they are used in various fields such as transportation, food (milk, meat), and horse racing. In addition, research and preservation on pure Mongolian breeds are being promoted under the implementation of the new Genetics of Livestock Resources' act in Mongolia. However, despite the implementation of this act, genetic research on Mongolian horses using microsatellites (MS) has not progressed enough. Therefore, this study was conducted to analyze the genetic polymorphism of five breeds (Gobi shankh, Tes, Gal shar, Darkhad, and Undurshil) using 14 MS markers recommended by International Society for Animal Genetics (ISAG). The mean number of alleles (MNA) was 8.29, expected heterozygosity frequency (H_Exp) was 0.767, observed heterozygosity frequency (H_Obs) was 0.752, and polymorphism information content (PIC) was 0.729. The Nei's genetic distance analysis showed that the genetic distance between Gobi shankh and Darkhad horses was the farthest, and the other three breeds, Tes, Gal shar, and Undurshil were found to be close to each other. Similarly, the principal coordinate analysis (PCoA) and factorial correspondence analysis (FCA) showed that the Gobi shankh and Darkhad horses were genetically distinct from other breeds. On the other hand, it appears that Tes, Gal shar, and Undurshil horses, which are genetically similar, most likely interbred with each other. Therefore, it is expected that these results will help the conservation of genetic resources in Mongolia and the establishment of policies related to Mongolian horses.

Understanding the regional distribution of swans in the lower Nakdong River area is also important for the continuous habitat of swans according to changes in the surrounding environment of the area. This study was conducted to understand the regional distribution aspect of swans (Cygnus spp.) downstream of the Nakdong River, Republic of Korea, from October 2013 to September 2018. In the estuary, a small ship was used to move along a certain route and observe it with the naked eye or binoculars, and in the land area, Line transect census and Point census method were conducted in parallel. During this period, two species and 34,647 individuals of swans were observed, including 34,356 Whooper Swans (Cygnus cygnus) and 291 Tundra Swans (Cygnus columbianus). The average number of individuals observed in 15 different areas was 1172, 103, 214, 1825, 1850, 13, 318, 1, 0, 1, 11, 21, 5, 0, and 239 respectively. The total average of the number of individuals in these areas was 384.76. The numbers differed significantly among the survey areas (Kruskal-Wallis test, X2=4349.01, P < 0.001). Particularly, the numbers were larger in Eulsukdo, Lower Eulsukdo, and Daemadeung than in the other regions. In conclusion, as long-term survey data, it can be used as basic data to analyze the distribution of swans due to environmental changes caused by the development of the Nakdong River, predict changes in the habitat status of migratory birds, and prepare measures necessary for preservation.
