This study investigated the field application and the acceptance test of the meal service for the elderly (${\ge}$ 65 years) community halls in Jeonnam and Gyeongbuk. The acceptance scores of bean rice and glutinous rice were the highest among the tested cooked rice varieties in Jeonnam and in Gyeongbuk, respectively (P<0.05). The acceptance scores of tofu soybean paste soup and spinach bean paste soup were the highest among different soups, in Jeonnam and Gyeongbuk, respectively. The scores of menu 5 (bean rice, tofu and bean paste soup, pan-fried pork, green laver salad, kimchi, soy milk) and menu 1 (cereal rice, fermented soy bean soup, hard-boiled quail's egg, crown daisy salad, kimchi, mandarin) were the highest in Jeonnam and Gyeongbuk, respectively, in terms of overall acceptance (P<0.05). The average cost of each meal in two provinces was $2012{\pm}323$ won. The amount of leftovers from menu 5 (Bean rice, Tofu and soybean paste soup, Pan-fried pork, Seasoned green laver, Kimchi, Soy milk) was the lowest in Jeonnamin, while the one from menu 2 (rice, leaf beet and soybean paste soup, sated vegetables with potato noodle, hard-boiled potato, kimchi, cherry tomato) was the lowest in Gyeongbuk.

For quarantine purpose, we developed the RT- and nested PCR module of Tomato black ring virus (TBRV), Arabis mosaic virus (ArMV), Cherry leafroll virus (CLRV) and Grapevine fanleaf virus (GFLV). The PCR modules, developed in this study make diagnosis more convenient and speedy because of same PCR condition. And also, the methods are more accurate because it can check whether the result is contamination or not using the mutation-positive control. We discard or return the 27 cases of Nepovirus infection seed by employing the module past 3 years. This study provides a rapid and useful method for detection of four quarantine plant viruses.

This study was carried out to evaluate the suitability of simple sequence repeat (SSR) markers for varietal identification and genetic diversity in 28 commercial tomato varieties. The relationship between marker genotypes and 28 varieties was analyzed. Of the 219 pairs of SSR primers screened against ten tomato varieties, 18 pairs were highly polymorphic with polymorphism information content (PIC) ranging from 0.467 to 0.800. Among the polymorphic loci, two to nine SSR alleles were detected for each locus with an average of 3.3 alleles per locus. Genetic distances were estimated according to Jaccard's methods based on the probability that the amplified fragment from one genotype would be present in another genotype. These varieties were categorized into cherry and classic fruit groups corresponding to varietal types and genetic distance of cluster ranging from 0.35 to 0.97. The phonogram discriminated all varieties by marker genotypes. The SSR markers proved to be useful variety identification and genetic resource analysis of tomato.

These experiments focused on processing low sugar fig jam having marketability by selected substitute for extracted and purified pectinesterase (PE), colorant for colour improvement, food additive to make texture better, and stabilizer for stable storage. Cherry tomato pulp as PE substitute to hydrolyze pectin substance in fig pulp into low-methoxyl pectin was most effective among used vegetables and fruits pulp. Carmacid-R among natural colorants for imprving colour, addition of 20% starch syrup as sugar substitute for texture and addition of $MULTIPHOSE^{TM}$ for red colour change control at cold storage were effective. The low sugar fig jam processed by using the above selected materials showed higher score than others (typical jam and orange PE low sugar fig jam) for colour in sensory evaluation and did no significant difference in taste, odor, texture and overall acceptability.

Purpose: This study aimed to characterize the recipes of Hwachae in Korean cookbooks published from the 1600's to 1940's. Methods: We conducted a content analysis of thirteen old cookbooks (Eumsikdimibang, Jubangmun, Jeungbosallimgyeongje, Kyugonyoram, Imwonsibyukji, Gyuhapchongseo, Sieuijeonseo, Buinpilji, Chosunyorijebub, Chosunmusangsinsikyorijebub, Ganpyeonchosunyorijebub, Chosunyori, Chosunyoribub). We collected a total of 99 recipes of Hwachae and analyzed the ingredients used and characteristics of the recipes according to five groups of Hwachae: noodle type Hwachae, dumpling type Hwachae, fruit Hwachae, flower Hwachae, and the others. Results: The noodle type Hwachae included Changmeyon, Smyeon, Nanmyeon, and Waemyeon. Mung bean (81.0%) and Schisandra (95.2%) were mostly employed as solid ingredient and as beverage base, respectively. In the noodle type Hwachae, Wonsobyeong and Sudan belonged to the dumpling type Hwachae, in which mung bean (51.7%) was mostly used as solid ingredient and just water without any additive was used as the most popular beverage base (62.1%) unlike in other types of Hwachae. There were various types of fruit Hwachae, which used different fruits as solid ingredient such as pear, peach, cherry, strawberry, etc. Pears (44.4%) have been employed as the most popular ingredient and sweets such as honey and sugar have been used in all the fruit Hwachae. The flower Hwachae included Hwamyeon, Sunchaehwachae, Jangmihwachae, and Bomhwachae. In all the flower Hwachae, schizandra has been used as a beverage base. Conclusion: These findings provide basic information required for developing standard recipes of traditional Hwachae.

Purpose: Monitoring and control of environmental condition is highly important for optimum control of the conditions, especially in greenhouses and plant factories, and the condition is not uniform within the facility. Objectives of the study were to investigate variability in soil water content and to provide information useful for better irrigation control. Methods: Experiments were conducted in a strawberry-growing greenhouse (greenhouse 1) and a cherry tomato-growing greenhouse (greenhouse 2) in winter. Soil water content, electrical conductivity (EC), and temperature were measured over the entire area, at different distances from an irrigation pump, and on ridge and furrow areas. Results: When measured over the entire greenhouse area, soil water content decreased and temperature and electrical conductivity increased over time from morning to afternoon after irrigation. Water content decreased by distance from the irrigation pump up to 70 m and increased after that, and temperature showed an inverse pattern. Soil water contents on the ridge were lower than those on the furrow, and the differences were 10.2~18.4%, indicating considerable variability. The lowest EC were observed on the furrow and highest values were observed on the ridge. Soil water contents were less and temperature levels were greater at the window side than in the center locations. Conclusions: Selection of number and location of soil water content sensor would be the first step for better water content monitoring and irrigation control. Results of the study would provide basic data useful for optimum sensor location and control for underground greenhouse environment.

In this study, seafood products (n=26) sold on sushi buffet restaurants in the city of Wonju were monitored by analyzing sequences of DNA barcode markers (cytochrome c oxidase subunit I and 16S ribosomal RNA genes). NCBI BLAST database was screened with the barcode sequences analyzed as a query for species identification. The BLAST search revealed that fifteen samples (58%) analyzed were consistent with their labeling information; however, the ingredients used in seven samples (27%) were not compliant with their label information. In the case of these mislabeled products, ingredients for sutchi catfish sushi and cherry bass sashimi were identified as Pangasianodon hypophthalmus and Lampris guttatus, respectively. For Japanese flying-fish roe sushi and Pacific herring roe sushi, roe of Mallotus villosus was used as an ingredient. Amphioctopus fangsiao and A. membranaceus were used in octopus sushi and soybean-marinated squid products, respectively. This monitoring result can contribute to the protection of consumer rights and the reduction of fraudulent practices in the food industry.

Ultrathin films were coated on low density Polyethylene (LDPE) food packaging films by plasma polymerization of methane, acetylene, hexamethyldisiloxane (HMDSO), and HMDSO+oxygen to improve the barrier property of the LDPE films. The film coated in HMDSO +oxygen (flow rate: 0.6+ 9.0 SCCM) plasma at 40 W for 10 min showed the highest improvement in the barrier property against oxygen, reducing the permeability of oxygen as much as 18.6 times. The film coated in acetylene (flow rate 0.75 SCCM) plasma at 10 W for 10 min showed the highest improvement in the barrier property against carbon dioxide and moisture, reducing the permeability of carbon dioxide and moisture as much as 12.0 and 3.0 times, respectively. In addition, cherry tomato, cucumber, and mushroom (Flammulina velutipes) wrapped with the coated films were kept fresh $1.5{\sim}3.0$ times longer than those wrapped with an LDPE film.

This study was conducted to obtain the optimal spray time for Pseudaulacaspis prunicota (Maskell) (Homoptera: Diaspididae) in early seaon in Jeju. Oviposition time of overwintered females and activity of hatched nymphs of P. prunicola were monitored, and the phenology data were compared with the outputs estimated by a degree-days model of P. pentagona (Targioni-Tozzetti)). Overwintered females of P. prunicola began to lay eggs from mid to late April, and the eggs started to hatch from early May followed by the active migration of the hatched nymphs during mid May. The phenological events of P. prunicola in early season were likely comparable with those of P. pentagona reported in southern Korea and in central Japan. A degree-day model, which predicts the proportion of >50% hatched egg batches of P. pentagona (y=1[exp(-(-a+bx))]; y, proportion; x, degree-days based on $10.5^{\circ}C$ from 1 January; a=-18.80 and b=0.073), accurately described the migration time of P. prunicola hatched nymphs. Thus, it is considered that the degree-day model can be used for predicting the optimal spray time for P. prunicola in early season.
