희나리 고추에서 분리한 곰팡이를 현미에 배양하여 실험동물(rat)에 투여하였을 때 Colletotrichum, Diaporthe, Diaporthopsis, Botryosphereia, Aspergillus, Fusarium의 경우 독성을 나타내지 않았으나 Alternaria alternata로 동정된 곰팡이는 독성을 나타내었다. A. alternata를 배양한 현미를 투여한 실험동물은 사료 섭취량이 상대적으로 낮았으며, 체중 감소를 보였고 2주안에 치사하였으며, 위, 소장, 간의 확대가 관찰되었다. Alternaria속 곰팡이는 17종이 분리되었으며 이들 중 8종은 고추즙과 현미에 배양하였을 때 모두 상당량의 tenuazonic acid를 생산하였고, 현미 배지에서만 alternariol과 alternariol monomethyl ether 독소가 추가로 소량 검출되었다. 건조 과정에서 곰팡이가 번식된 고추는 유해한 대사물의 존재 가능성이 있으므로 식품 안전을 위해 곰팡이 번식을 최대한 억제할 필요가 있다.

The present study determined the estimated dietary fiber (DF) intake per capita of Korean from 1991 to 2001 and analyzed the major food sources of dietary fiber for Korean using the data on per capita consumption of each food reported in the Korean National (Health and) Nutrition Survey Reports and the recently established DF database by the Korean Nutrition Society. The estimated mean daily DF intakes of Korean during the last 11 years $(1991{\sim}2001)$ were in the range of $19.25{\sim}21.22\;g\;or\;9.97{\sim}11.99\;g/1,000\;kcal$ with a small range of fluctuations. As of 2001, average DF intake per capita of Korean was estimated as 20.92 g or 10.59 g/1,000 kcal. The average DF intake level was under the Adequate Intake for DF (12 g per 1,000 kcal) of the Dietary Reference Intakes (DRIs) for Koreans established in 2005. The level of DF intake was relatively lower in small city residents compared to the large city or rural area. The top two major food group sources of DF for Korean were vegetables and cereals, in addition, legumes, fruits, seaweeds and seasonings were included among top five food groups. The ratio of DF intake from fruits was gradually increased but the ratio from legumes was steadily decreased during the last 11 years. The mostly contributed single foods for DF intakes of Korean were Kimchi and rice regardless of year and area. Percentage of DF intake from top ten single foods was continuously decreased from 65% in 1991 to 51 % in 2001. The results of this study revealed that DF intakes of Korean as of 2001 is insufficient compared to the Adequate Intake for DF for Korean and the source of fiber in Korean diet has been more various. Therefore the beneficial health effects of DF and the increased consumption of DF from a variety of food sources should be continuously emphasized through the nutritional education.

The pepper anthracnose fungus, Colletotrichum scovillei, causes severe losses of pepper fruit production in the tropical and temperate zones. RAC1 is a highly conserved small GTP-binding protein in the Rho GT-Pase family. This protein has been demonstrated to play a role in fungal development, and pathogenicity in several plant pathogenic fungi. However, the functional roles of RAC1 are not characterized in C. scovillei causing anthracnose on pepper fruits. Here, we generated a deletion mutant (𝜟Csrac1) via homologous recombination to investigate the functional roles of CsRAC1. The 𝜟Csrac1 showed pleiotropic defects in fungal growth and developments, including vegetative growth, conidiogenesis, conidial germination and appressorium formation, compared to wild-type. Although 𝜟Csrac1 was able to develop appressoria, it failed to differentiate appressorium pegs. However, 𝜟Csrac1 still caused anthracnose disease with significantly reduced rate on wounded pepper fruits. Further analyses revealed that 𝜟Csrac1 was defective in tolerance to oxidative stress and suppression of host-defense genes. Taken together, our results suggest that CsRAC1 plays essential roles in fungal development and pathogenicity in C. scovilleipepper fruit pathosystem.

Sample presentation, which means how to set samples to an NIR instrument, is very important in Near Infrared (NIR) Spectroscopy. When sample presentation is not suitable for the samples that you use, very good spectra can not be obtained even if you use a sophisticated NIR instrument. In my presentation, various NIR sample presentations for agricultural products such as intact fruits, single grains, vegetable juice and the others will be explained. In case of peaches with thin peel, the fiber optics of Interactance can be used. However, the fiber optics are not suitable for oranges with relatively thick peel. In this case, transmittance method is useful. As for a small sample such as single grains, a specially designed cell is needed. The cell in transmittance mode has been developed and then applied to single kernels of rice and soybean. In this case we also used the fiber optics. As regards liquid type of sample, a cuvette cell made of quartz in transmittance mode is popular. However, it is time-consuming to wash and dry it. In order to compensate this disadvantage the sample presentation using normal test tubes as sample cells have been developed and applied to milk, rumen juice and urine of a milking cow. An individual test tube can be used for each sample if you use the calibration equation with sample cell compensation. The test tube cell has also been applied to spinach juice for determination of undesirable constituents. It is concluded that sample presentation is most important for NIR Spectroscopy.

In robotic harvesting, a gripper to manipulate the fruits needs to be attached to the robot system. We proposed a flexible robot gripper that can actively respond to the shape of an object such as fruits in the previous work. However, we found that there is a possibility of not being reliably gripped when the object slides during contact with a finger. In this paper, the improved gripper design is proposed to fundamentally solve the problems of the previous gripper. The position of the finger and the maximum closed position are changed, and the design improvement is performed to increase the grip stability by changing the installation angle of the link portion of the finger. Based on the improved design, a modified gripper is fabricated by 3-D printing, and then gripping experiments are performed on spherical object and fruit model object. It is shown that the gripper can stably grip the objects without excessive bending of the finger link of the gripper. The contact pressure between the finger and the surface of the object is measured, and it is verified that it is a sufficiently small pressure that does not cause damage to the fruit. Therefore, the proposed gripper is expected to be successfully applied in harvesting.

Recently, an increasing number of urban farmers are growing fresh vegetables and fruits themselves using urban garden or weekend farms. In other words, this is called urban agriculture. After the Industrial Revolution in the 18th century, the agricultural society changed from an agricultural society to an industrial society, and the population began to flock to the cities. With the continued increase of urban population, countries with abundant capital were able to control the distribution structure of food supplies and trade agreements among countries. Since energy consumption and carbon dioxide emissions caused by agricultural product movements have emerged as the main culprits of global warming, and our table is threatened by safety due to food supply that has no genetic modification or knowledge of the cultivation process, urban agriculture is already taking hold in the West. In other words, as agriculture met cities, its role grew. Each region actively conducts agricultural activities for raising poultry as well as growing vegetables and fruits by using flower beds of detached houses in the city center, rooftops of high and low buildings, or school playgrounds and small tributaries of land. The purpose of this study is to analyze and understand the significance and type of urban agriculture and to examine the cases of domestic and foreign urban agriculture based on this and to seek the developing direction of urban agriculture, which is gradually increasing. Tired of growing competition and rapid change, urbanites are seeking health and relaxation and are planning to present development measures for urban farming and conduct follow-up research to ensure safe food.

일인가구의 증가 및 소비행태의 변화, 그리고 마트는 대형화 되고 있는데 반하여 포장 형태는 소포장 용기로 바뀌고 있으며, 수출되는 농산물 특히 과일 및 관련 작물의 수출시 소규모 패키지화되고 있고, 수출시점에 CO₂등의 선도처리를 하고는 있으나 운송 기간내 패키지내부 작물의 선도를 보장하기 어려웠다. 따라서 농산물 유통시 운송과정이나 진열시에 품온이 바뀌어 미생물에 의하여 작물이 변질되는 것을 방지하기 위한 신선도유지제로 소포장 용기로 유통하는 농산물에 적용하기 위한 새로운 신선도 유지 방법의 제공이 필요한 상황으로 윤통과정의 혁신을 가져올 수 있는 방안에 대하여 연구하게 되었다.
