Open-source software developments are basically Internet-based communities that voluntarily collaborate in developing software on the Internet and such Internet communities have become an important cultural and economic phenomenon. As a result, the emergence of open-source software has presented a challenge to the traditional offerings by providing free alternatives. The objective of this article is to review the possibility of the adoption of open source software in the creation of digital libraries, highlights advantages and disadvantage preservations. Among our objective also explaining the request of such software at the present time and the criteria evaluated in the digital preservation through surveying the best open source software from the reality of intellectual production, and standards that are being built to evaluate and choose what software to create a digital library without other software available. To achieve the above objectives, we shed the light on the top 11 open-source software to manage Libraries in addition to standards that may represent the basic building block for the selection of the appropriate systems to the needs of the digital library. This article relied on the descriptive approach by reviewing a series of studies and scientific research works related to the subject of the current study. Accordingly, the most prominent of the findings of this work is its illustration of the close association between open source software and the library community, both of which represent free culture. Also it is shown that the selection process of open source software has some obstacles most notably as there are no clear and reliable criteria for selecting these systems. Current study has concluded a set of recommendations, notably awareness of the role and importance of open source software and the facilities it provides in managing digital content.

본 연구는 순환식과 비순환식 수경재배 온실 내 특정 구역에서 잠재적인 병발생 가능성을 추정하기 위하여 미생물 시료의 채취 및 배양을 통하여 집락형성단위수(CFU)를 분석하였다. 시료의 채취는 배지를 기준으로 각 구역별 3cm 간격으로 $25cm^2$의 면적에 대해 4개의 구역을 각 온실별로 3회 반복하여 이루어졌다. 비순환식과 순환식 수경재배 온실에서 암면과 코이어를 배지로 사용하는 각 2개 농가를 조사대상으로 하였다. 진균류의 경우 비순환식 수경재배 온실에서 유의적으로 높은 수준의 집락형성단위수(CFU)가 관찰되었다. 세균류의 경우는 유의적인 차이는 관찰되지 않았지만, 순환식 수경재배 온실이 비교적 낮은 경향을 나타냈다. 위치 별 CFU의 비교에서는 순환식과 비순환식 모두 배액의 발생에 따른 환경조건의 변화가 적은 배지 부분에서 가장 낮은 수준의 CFU가 관찰되었다. 주성분 분석결과 온실 내 배액의 이동 경로 상에서 수집된 시료가 미생물의 개체수 변화에 많이 기여하고 있는 것으로 판단되었다. 순환식 수경재배 온실은 비순환식 수경재배 온실에 비해 미생물 증식억제에 유리한 조건에 있으며, 이는 외부 환경에 비해 비교적 단순한 생태계로 구성된 온실의 조건을 고려해 보았을 때 잠재적인 병 발생 가능성이 상대적으로 낮음을 의미한다.

The study presented attempts to analyze and categorize Chosun's food ingredients and culture through a Western perspective based on 32 representative Western documents pertaining to old Korea. Before modernization, Westerners visited Chosun during their visits to old China or Japan. Westerners were most active in Chosun from the open port period to the annexation of Korea to Japan occupation. They were teachers, missionaries, diplomats, and doctors visiting Chosun with personal goals. In 31 book traveler's journal, it records Chosen's mainly produced ingredients, such as grains, spices, fruits, cabbage, chicken, and chestnuts; foods from Chosen include kimchi, soup, and tofu. Foreigners especially liked foods made of eggs and chicken, but they did not enjoy Chosun's lack of sugar and dairy. Thirty-one book foreigners' records describe Chosun's Ondol, kitchen, crock, fermented foods, low dining tables, and chopsticks. Chosun people liked dog meat, unrestrained drinking culture, sungnyung, and tea culture. Foreign documentation on Chosun's food culture allows modern scholars to learn about Chosun people's lifestyles, as if their lives were a vivid picture.

In previous studies, we reported that sow which was transferred OPS-freezing embryos not able to deliver a piglet (Kim et al, 2004). This study was conducted to investigate a possibility of gilt as recipients which produce piglets after transfer of OPS-freezing embryos. All transferred embryos were prepared by in vitro production (IVP) system. In vitro culture (IVC) medium used glucose-free NCSU23 supplemented with 5mM sodium pyruvate, 0.5 mM sodium lactate and 4 mg/ml bovine serum albumin for 2 days at $39^{\circ}C$. From day 3 of IVC, 10% fetal bovine serum albumin was added to the culture medium. In preparing of freezing embryos, embryos were treated with 7.5 $\mu g/ml$ cytochalasin-B for 30 min and centrifuged at $13,000{\times}g$ for 13 min. And then, embryos were exposed sequentially to an ethylene glycol (EG) solution, aspirated into open pulled straw (OPS), and plunged or thawed into the liquid nitrogen. In embryo transfer (ET), we used two kinds of type (surgical method vs. non-surgical method). In surgical method of embryo transfer, $55\sim65$ embryo were transferred in both uterine horn of two recipient gilts by plastic straw. Non-surgical method which is like artificial insemination was performed on three gilts. Each 140 frozen embryos were transferred to two gilts and 40 fresh embryos to one gilt. Pregnancy establishment was shown one recipient at 45 days after ET. However, the one recipient was also aborted at 58 days after ET. These results suggest that gilts can be considered as a candidate of recipients for OPS-freezing embryo transfer.
