The seven oligonucleotides primers were consumed to produce the quantity of unique loci shared to each pen shell team (ULSEPT) and quantity of loci shared by the binary pen shell teams. 154 quantities of LSBPP, with a mediocre of 22.0 per primer, were noticed in the binary pen shell (Atrina pectinata) teams. 328 fragments were recognized in the pen shell team A (PSTA), and 257 in the pen shell team B (PSTB): 77 quantities of ULSEPT (23.48%) in the PSTA and 121 (47.08%) in the PSTB. The band-sharing amount (BS amount) between entity's no. 01 and no. 05 was the highest (0.884) between the binary PSTs. The median band-sharing amount of entities in the PSTA (0.685±0.011) was higher than in those invented from the PSTB (0.640±0.009) (p<0.05). The highest genetic distance presenting substantial molecular difference was between entities PECTINATA no. 06 and PECTINATA no. 04 (0.498). Through this study, it is possible a certain degree to contribute to increasing the cultivation of pen shells, conservation of species, protection of the natural environment, and preservation of ecosystems.

The purpose of this paper is to examine Paul Auster's Leviathan according to Slavoj Žižek's theory. Analyzing the characters in Leviathan, this paper chiefly discusses the postmodern subject's anxiety and obsessive repetition that the lack of the big Other led to. Section II explains the disintegration of the big Other and the subject's anxiety and obsessive repetition by the interpretation of the characters: Peter Aaron, Maria Turner, and Benjamin Sachs. Aaron wants to write on Sachs's life to overcome his uneasy subject's condition, and to establish the consistent and whole world. But his writing fails to meet his desire, owing to uncertainty of his understanding, and the incompleteness of his writing. In case of Maria, her uneasy subject's condition led to her obsessively repetitive picture-shooting herself and others, which proved to be a meaningless struggle for filling the void of the big Other and herself. Although Sachs already knows the lack and inconsistency of the big Other, he also repetitively tries to establish the consistent and whole Other. In Section III, this paper examines Sachs's terror as he struggles for the preservation of the big Other. His extreme striving also fails to reestablish the big Other as it loses its symbolic effectiveness in the postmodern era because he does not grasp the big Other as an empty Symbolic order, and rejects the premise of the big Other itself.

The purpose of this study is to find the differences between home economics before and after korean Independence of the dominance of Japanes Empire. The specific aimes are to compare the subject organization, educational purpose and subject contents etc. of home economics in korean school before with after the Korean Independence of the dominance of Japanes Empire. The methods to study were to analyze some documents(laws or regulations)and textbooks etc. at that time. The result of this study is summerized as follow. 1. The subject of home economics in primary school were‘Jaibong(sewing)’,‘Kasa(household affairs)’just before Korean Independence of Japan in 1945. But the subject of home economics changed to‘Yori(cooking)’,‘Jaibong’after Korean Independence in 1945. In 1946,‘Yori’and Jaibong were integrated in‘Kasa’. In 1954, ‘Kasa’changed to ‘Silkwa(Practical Course)’. The subject of home economics in middle or high girl school were‘Kajeong(home)’, ‘Yuga(nursing)’,‘Bogeon(preservation of health)’,‘Pibok(clothing)’just before Korean Independence in 1945. But the 4 subjects changed to‘Kasa’,‘Jaibong’,‘Suye(embroidery)’and the 3 subjects changed‘Sileop and Kajeong(home affairs)’again. 2. The hours per week assigned to home economics education were higher in high school years than in low school years both in primary schools and middle or high schools. 3. Among various home economics subjects, the hours assigned to‘Jaibong’were higher than any other home economics subjects. But The hours assigned to the‘Kasa’tended to increase in high school years. 4. The purpose of home economics education in schools before Korean Independence of Japan focused of fostering korean's loyalty to Japan Empire in the end and on cultivating womanly virtue etc. This tendency was more prominant in middle or high school than primary school. 5. Korean home economics education during about 10 years generally followed the home economics education of Japanes Empire. 6. The home economics education in primary school for school boys was practised after 1955(The period of 1th curriculum). Before that time was practised home economics education for school girls. 7. Generally home economics education in Korean schools was weakened after Korea became Independant of Japanes Empire in 1945. 8. The contents of home economics education after Korean Independence tended to follow those of Japan. Among domains of the home economics the rate of contents of‘siksainghwall(life of foods)’tended to be largest, the rate of‘Jusainghwal(life of house)’lowest in primary, while the contents of‘oeusainghwal(life of clothing)’tended to be largest, the rate of‘Jusainghwal(life of house)’lowest in middle education.

Although the demand of ready-to-eat (RTE) foods such as Kimbab is growing, large quantities and wide distribution of these foods is difficult due to their short shelf-life, exposed packaging with hygienic risk, and decreased quality at refrigerator temperatures. This study was undertaken to develop preservation and storage methods to extend the shelf-life of RTE rice products using microwave and packaging methods such as vacuum and modified atmosphere packages. RTE rice ball samples inoculated with Escherichia coli, Salmonella Typhimurium, Listeria monocytogenes, Staphylococcus aureus or Bacillus cereus were microwave treated for 0, 30, 60, 90 and 120 seconds. Populations of pathogens on the rice balls were significantly reduced with an increase in treatment time. There were more than 5 log reductions of all pathogens when the samples were microwave treated for 60 seconds. RTE rice balls inoculated with two pathogens (S. aureus and B. cereus) were packaged via air, vacuum, $N_2$ gas, and $CO_2$ gas following microwave treatment for 90 seconds. The initial S. aureus and B. cereus concentration before treatment was 7.60 and 6.59 log CFU/g, and these levels were reduced by 3.37 and 2.18 log CFU/g after microwave treatment. The levels of pathogens were significantly increased during storage time at room temperature. $CO_2$ packaging was the most effective at inhibiting microbial growth among the tested packaging methods. The levels of total mesophilic count, S. aureus and B. cereus after 5 days of storage were 7.7, 8.8 and 9.3 log CFU/g in air packaged samples and 2.4, 3.2 and 8.3 log CFU/g in $CO_2$ gas packaged samples, respectively. However, after 3 days of storage higher levels of B. cereus were observed in all samples, indicating that the samples were not safe to be consumed. Base on these results, microwave treatment and MAP packaging methods using $CO_2$ gas could be used as a potential method for extending the shelf-life of RTE foods.

막걸리의 소비와 저장성을 증진시키기 위한 기초연구의 일환으로 막걸리 발효 및 유통과정에서의 효모 수, 유기산 및 총산의 변화를 조사하였다. 발효가 진행됨에 따라 막걸리의 맛을 결정하는 데 중요한 역할을 하는 유기산인 lactic acid, succinic acid 외에 malic acid, citric acid도 막걸리 발효과정 중의 주요 유기산으로 보아야 될 정도로 많이 생성되었다. 그러나 oxalic acid, phosphoric acid, acetic acid는 전 발효기간을 통하여 검출되지 않았다. 막걸리 발효 중, 총산은 증가하였으나 pH는 비례적으로 감소하지 않았다. 유통과정 중 저장온도에 따른 막걸리의 유기산 변화를 관찰한 결과, $4^{\circ}C$에서 보관 시 막걸리의 일반적인 유통기한인 10일보다 2배가 긴 20일까지도 유기산의 변화가 거의 없음이 관찰되어 유통기한을 연장시켜도 될 가능성이 있음을 알 수 있었다. 그러나 $25^{\circ}C$에서 보관한 막걸리는 citric acid가 검출되지 않았고, lactic acid가 큰 폭으로 감소된 것으로 보아 쉽게 변질될 수 있음을 알 수 있었다. 또한 산패 지표물질인 acetic acid가 생성됨으로써 유통과정에 문제가 생길 수 있음을 알 수 있었다. 따라서 유통과정에서의 저장온도를 $4^{\circ}C$로 하면 최소 20일 이상 보관 가능함을 알 수 있었다.

In the ancient time wind is considered as the life . soul and the human's breath which represents essence of universal creation and the absolute power and also the messenger of the god or god's state. Greek's 'pneuma' , India's 'Brahman' and the Old Testament's 'ruach' are used to signify the wind. Also Wind(風) in traditional culture, it is related to 玄妙之道 of 花郞, the flower of youth in Shilla dynasty and sexual intercourse in shaman's dream which can be thought as Freud's libido. In this aspect we can see the connection between the wind and the libido which can be meaning of sexual desire. Ancient Chinese wrote word ‘風’ as phoenix, the god's bird, the phoenix in inscriptions on bones and tortoise carapace(甲骨文) because one can feel the wind but can’t see it. The word Ki(氣) origins from 風 therefore 風 is 氣's fundamental notion. The wind can be understood by ki which travels around the world to create all nature. And the Wind is associated with 風化, 玄鳥, 八僧舞, which are related with reproduction. In the book of change (周易) the 震巽卦 ; 雷風 come under wind which means the function of ki and also menas the 精(essence of life) of 恒久(eternity) means the reprodution ; that performs succession of life. In the Oriental Medicine 氣 is a phenomenon that appears by movement of Ki by 相火(Ministerial fire). 相火 is core of the succession of life which means preservation of descendants; therefore 風 has very similar concept with sexual desire. 風 is the beginning ki of universe and in human body aspect 風 belong to the Liver Meridian. If 風 makes movement then the Pericardium Meridian of Hand Kwolum responds and the genital organs which belongs to Liver Meridian of Leg Kwolum reproductive function by contraction and expansion. Generally 風 understood as movement and origination and this is recognized as meaning of 氣. Therefore as studied above the present writer believe m. participates closely to reproductive function.
