The prefix 'bio' with the meaning of 'life,' has been used for biotechnology, biochemistry, bioengineering, biomedicine, bioethics, bio-information as well as 'bio art' since 1990s. Bio art is an art as life itself and a kind of new direction in contemporary art that manipulates the processes of life. Bio artists use the properties of life and materials as scientists in laboratory of biology, and change organisms within their own species, of invents life with new characteristics. Technologically and socio-culturally, bio art has been connected with bioengineering. This essay is on the bio art that use vegetables, and on the specified gaze of so-called 'Sci-Artists.' Not only the genetically modified vegetables like works of George Gessert, Ackroyd & Harvey, and Eduardo Kac, but also the works made from the critical viewpoint like those of Paul Vanouse, Natalie Jeremijenko, and Amy Youngs, have 'the molecular gaze'(Suzanne Anker and Dorothy Nelkin's concept) of the genetic age in their art works. As the art history have showed, artists' gazes have insights about social problems that surround us. Bioartists' gazes reveal their insights about social and ethical problems, possibly concealed by science itself. Those problems are about results from practical discoveries of the sequencing of the genome, genetic engineering, cloning and reproduction of human and animals, body transformation, and the commercialization of cell and genes etc. We can find the significance of bioart in the molecular gaze about those problems, and we can rethink the identity of human, the reception of social influences from bio-technology and medicine.

This paper investigated the effects of a government production and shipment stabilization policy and the improvement plan for vegetables in Korea. In this study, a simulation focused on the changes in farm income for Chinese cabbages & radishes using scenarios. The result shows an increase in farm income according to the government policy. In the short-term, demand and supply are fixed, and the policy effect is positive due to the price support effect of the project. However, for mid- to long-term, the price decreases due to the expansion of supply by business beneficiaries, which is likely to be adversely affected by an unstable supply and demand. This increases the burden of government and local government subsidies. This phenomenon is expected to be amplified as the ratio of production and shipbuilding stabilization programs and items expand. When expanding items and adjusting and setting the percentage of participation in the project, it is desirable to set and operate the appropriate business ratio taking into consideration the demand. To improve the effectiveness of the policy, the following remedies were suggested. First, national supply and demand guidelines should be set up, and the autonomous supply and demand control of the producers should be guided by the different preservation according to the implementation of the supply and demand control obligation. As for detailed equipment, it is necessary to establish the reproduction price for each item, set the base price for each wholesale market, increase the incentive for the producers to participate, and fund a business budget to secure business stability.

어린잎 채소는 조직이 연하고 부드러워 가공, 포장, 유통시에 물리적인 상해를 받기 쉬우며 수확 후 수분증발 및 성분 변화 등으로 품질이 급격히 저하된다. 본 연구는 어린잎 채소 중에서 다채의 수확 후 생리특성을 구명하고 적정 포장방법을 개발하고자 수행하였다. 공시재료는 연구소 온실에서 2007년 1월 29일에 다채 종자를 플러그 트레이에 파종하여 30일 정도 키운 다채를 사용하였으며, 수확 후 $2^{\circ}C$에서 12시간 예냉 처리한 후 P-plus 필름, $50\;{\mu}m$ PP필름, PET용기에 각각 30 g씩 소포장하여 유통온도를 $8^{\circ}C$로 저장하면서 품질특성 변화를 주기적으로 조사하였다. 수확당시 어린잎 채소 다채의 생육은 무처리구에 비해 물리적 스트레스 처리구에서 초장과 초폭 모두 낮은 값을 나타내었다. 중량감소의 경우 물리적 스트레스 처리한 시료를 P-plus 필름으로 포장한 경우가 가장 적은 생체중 감소를 보였고 그 다음으로는 $50\;{\mu}m$ PP필름, PET용기 순이었다. 어린잎 채소 다채의 색도변화는 P-plus 필름과 $50\;{\mu}m$ PP필름에서 다소 완만하게 변화량을 나타내었으며 처리간 큰 유의차를 보이지 않았고 PET용기에서 가장 급격한 변화가 나타나서 황화 현상이 관찰되었다. 결론적으로 어린잎 채소 다채는 물리적 스트레스를 처리한 경우가 무처리구에 비해 생육은 적었지만 중량감소나 색도변화에서 비교적 원만한 값을 나타내었고 세포조직학적으로 관찰해보면 세포의 치밀도가 증대되어 수확후 가공적성에 영향을 미치리라 기대하며, 다채에서는 P-plus 필름과 $50\;{\mu}m$ PP필름 포장이 선도유지에 적합하였음을 알 수 있었다.

Plants protect against viruses through passive and active resistance mechanisms, and in most cases characterized thus far, natural recessive resistance to potyviruses has been mapped to mutations in the eukaryotic initiation factor eIF4E or eIF(iso)4E genes. Five eIF4E copies and three eIF(iso)4E copies were detected in Brassica rapa. The eIF4E and eIF(iso)4E genes could interact with turnip mosaic virus (TuMV) viral protein linked to the genome (VPg) to initiate virus translation. From the yeast two-hybrid system (Y2H) and bimolecular fluorescence complementation (BiFC) assays, the TuMV-CHN2/CHN3 VPgs could not interact with BraA.eIF4E.a/c or BraA.eIF(iso)4E.c, but they could interact with BraA.eIF(iso)4E.a in B. rapa. Further analysis indicated that the amino acid substitution L186F (nt T556C) in TuMV-UK1 VPg was important for the interaction networks between the TuMV VPg and eIF(iso)4E proteins. An interaction model of the BraA. eIF(iso)4E protein with TuMV VPg was constructed to infer the effect of the significant amino acids on the interaction of TuMV VPgs-eIF(iso)4Es, particularly whether the L186F in TuMV-UK1 VPg could change the structure of the TuMV-UK1 VPg protein, which may terminate the interaction of the BraA.eIF(iso)4E and TuMV VPg protein. This study provides new insights into the interactions between plant viruses and translation initiation factors to reveal the working of key amino acids.

The awareness of ritual foods in general rituals were surveyed and compared in the Gyeonggi and Gyungsangbuk-do areas in order to identify the characteristics of Korean rituals and establish desirable ritual foods. As materials for "Jeon" (fried pan cakes) in rituals, fish fillets, meat and vegetables were largely used in the Gyeonggi region. In the Gyeongbuk region, all three of these ingredients were the most highly used for "Jeon" also. In the case of rice cakes, "Songpyun" steamed on a layer of pine needles, "Jeolpyun" and "Sirudduk", with a red beans, were mostly used in Gyeonggi-do, while "Songpyun", "Jeolpyun" and "Ingelmi" were largely used in Gyeongsangbuk-do. As seasoned vegetables and herbs, fernbrakes, root of bell flowers, green bean sprouts and bean sprouts were largely used in Gyeonggi-do region, whereas, fernbrakes, bean sprouts, root of bell flowers and spinaches were mainly used in Gyeongbuk region. The use of fernbrakes was highest in both regions. With regard to the number of side dishes, 2∼3 kinds of seasoned herbs and 3∼4 kinds of fruits were mostly used, but with slightly higher numbers in the Gyeongsangbuk-do than the Gyeonggi-do region. With regard to liquor used for rituals, clear strained rice wine was used most in the Gyeonggi-do area, while more unrefined rice wine was used in the Gyeongbuk region. Meat was the most used ingredient in broth slices of dried meat and cod were highly used in the Gyeonggi region, but slices of dried squid were most widely used in the Gyeongbuk region. Most households in both regions tended not to use raw fish in the rituals, and as for the ingredients of Korean Kabobs, meat was the most widely used, then fish and finally vegetables were the most used ingredients. Beef soup was the most used, but more green vegetable soup was used in the Gyeongbuk than the Gyeonggi region. Sweet drink made from fermented rice (sikhe) was generally used in the rituals. It was the most widely used in the Chusok-Hangawi Ritual in the Gyeonggi region, while it was used in the New Year's Ritual in the Gyeongbuk region.

Various robots were developed for harvesting fruits and vegetables. However, each robot was designed for a specific task such as harvesting apples or vegetables. This has been a big hurdle in application of robots to agriculture. A new type of hybrid manipulator with both parallel and serial joints was developed and designed to apply to various kinds of field operations. The hybrid manipulator had 2 extra degree of freedom in serial joints which made it flexible in switching one to the other type of hybrid manipulator, for example, PUMA to SCARA. And it was designed to harvest heavy fruits such as musky melons or water melons even behind leaves or branches of tree. This hybrid manipulator showed less than $\pm1mm$ position error. It was concluded that the hybrid manipulator was an effective and feasible tool to perform various works and to increase working performance.

Since its introduction in"Jeungbosallimgyeongje" in the mid-1700s, Chogyetang has continuously changed as a cooked food while still reflecting the era as in the following four phases. In the first phase from 1766 to 1920, Chogyetang was served as a hot pot dish consisting of boiled chicken with spring onions, vinegar, soy sauce, oil, and egg. The second phase from 1930 to 1950 involved the removal of vinegar, an important seasoning. Instead, a wider variety of materials such as beef, sea cucumber, abalone, cucumber, and mushroom were added. Third, from the late-1950s to 1980s, there were significant changes both in the materials and recipe. Chogyetang was changed into a cold food for consumption in the summer in which sesame, a new material, was added to make soup. The prepared soup was then poured over the chicken and vegetables. Fourth, from the late-1980s to the present, sesame, the main ingredient added in the third phase, was removed. Instead, vinegar, mustard, and sugar were added in order to increase taste. Therefore, Chogyetang has been changed into an a la carte menu item in which vegetables and noodles are added to boiled chicken, and it has become a popular summer food consumed when eating-out.
