Objectives: Intake of fruits and vegetables has protective effects against stroke attack. This study intended to examine the status of consuming fruits and vegetables and to find out which factors may influence the frequency of consumption of fruits and vegetables in individuals with a history of stroke. Methods: The data of 208 subjects from 5th (2010, 2011) Korea National Health and Nutrition Examination Survey (KNHNES) who reported a stroke diagnosis was used for analysis. To identify major factors influencing the consumption of fruits and vegetables, a classification-tree analysis was carried out. Results: Among those who reported a stroke diagnosis, the frequencies of consumption of fruits and vegetables were influenced by their age, place of residence (urban or rural), economic status, educational level, occupation, number of family members, frequency of eating out, and having meals (breakfast or lunch) with family members. Two factors from fruits and three factors from vegetables were generated by exploratory factor analyses. Urban residents ate fruits and vegetables more frequently in all factors than rural residents. Eating frequencies of 'seasonal fruits (orange, apple, strawberry, melon, pear and watermelon)', 'easily-accessible fruits (persimmon, tangerine, grape, peach, banana)', and 'Western-style vegetables (cabbage, mushroom, carrot, tomato, spinach)' were influenced by the socioeconomic status. Eating frequencies of 'Korean-style vegetables (bean sprout, radish leaves, pumpkin/squash, sea weed)', 'preserved vegetables (Korean cabbage, radish, laver, cucumber)' were influenced by having breakfast with family members. Conclusions: The results of this study suggested that by eating more fruits and vegetables, more preventive effects against secondary stroke attack are expected in stroke patients who live in the rural areas and who do not eat breakfast with family members. In addition, more outreach and education programs are needed for them.

우리나라 서남권에 해당하는 서해안고속도로가 통과하는 전라북도 고창지역은 점토분이 많아 내포돼 있는 황토가 많다. 황토는 수박이나 고구마 같은 작물의 재배에는 양질의 토사이지만, 도로를 구축하기 위한 노상재료로 사용하는데는 원하는 강도값을 얻기가 힘들 토사였다. 이 연구 대상구간의 지역은 절토부의 노상재료가 원하는 재료의 품질기준을 충족시키지 못하였다. 노상층의 재료 특성을 보면, ＃200번체 통과량이 25～82％정도로 지하수위가 거의 노상면과 일치하여 자연함수비 과다로 시공시 노상토의 지지력 확보가 불가능한 것으로 판단되었다. 본 연구는 이와 같이 지지력이 부족한 현장에 적절한 절토부 노상지지력의 확보방안을 수립하여 원하는 공정을 추진함으로서 보다 안전하고 튼튼한 고속도로를 건설하는데 있었다.

The infectious full-length cDNA clones of Cucumber green mottle mosaic virus (CGMMV) isolates KW and KOM, which were isolated from watermelon and oriental melon, respectively, were constructed under the control of the cauliflower mosaic virus 35S promoter. We successfully inoculated Nicotiana benthamiana with the cloned CGMMV isolates KW and KOM by Agrobacterium-mediated infiltration. Virulence and symptomatic characteristics of the cloned CGMMV isolates KW and KOM were tested on several indicator plants. No obvious differences between two cloned isolates in disease development were observed on the tested indicator plants. We also determined full genome sequences of the cloned CGMMV isolates KW and KOM. Sequence comparison revealed that only four amino acids (at positions 228, 699, 1212, and 1238 of the replicase protein region) differ between the cloned isolates KW and KOM. A previous study reported that the isolate KOM could not infect Chenopodium amaranticolor, but the cloned KOM induced chlorotic spots on the inoculated leaves. When compared with the previously reported sequence of the original KOM isolate, the cloned KOM contained one amino acid mutation (Ala to Thr) at position 228 of the replicase protein, suggesting that this mutation might be responsible for induction of chlorotic spots on the inoculated leaves of C. amaranticolor.

Korean ginseng (Panax ginseng) is a dicotyledonous, medicinal, perennial plant belonging to the genus Panax of the family Araliaceae. We investigated the occurrence and incidence of plant viruses in Panax ginseng in Korea. A total of 656 leaf samples were combined into one and total RNA was extracted from the polled sample, using RNA sequencing (RNA-Seq), a metatranscriptome analysis of the plant virome was conducted. The virus present in Panax ginseng was confirmed by reverse transcription polymerase chain reaction (RT-PCR) assay using virus-specific primers. In RNA-Seq data analysis, the multiplication protein of four viral contigs including Aristotelia chilensis virus 1 (AcV1), Turnip mosaic virus (TuMV), Watermelon mosaic virus (WMV), and Tobamovirus multiplication protein were discovered. From our metatranscriptome analysis and RT-PCR assay, TuMV and WMV were detected, whereas the three viruses reported in China such as tomato yellow leaf curl China virus; panax notoginseng virus A; and panax virus Y were not found in this study. The distribution of domestic ginseng viruses seems different from that recorded in China. Overall, this is the first plant virome analysis of Panax ginseng in Korea.

AP2/EREBP gene family consists of transcription factor genes with a conserved AP2 DNA-binding domain and is involved in various biological processes. AP2/EREBP gene families were identified through genome-wide searches in five Cucurbitaceae species including cucumber, wild cucumber, melon, watermelon, and bitter gourd, which consisted of more than 100 genes in each of the five species. The gene families were further divided into five groups including four subfamilies (ERF, DREB, AP2 and RAV) and a soloist group. Among the subfamilies, DREB subfamily which is known to be related to abiotic stress response was more analyzed and a total of 25 genes were identified as Cucurbitaceae homologues of Arabidopsis CBF/DREB1 genes which are important for abiotic stress-response and tolerance. In silico expression profiling using RNA-Seq data revealed diverse expression patterns of cucumber AP2/EREBP genes. AP2/EREBP gene families identified in this study will be valuable for understanding the stress response mechanism as well as facilitating molecular breeding in Cucurbitaceae crops.

A total of 51 vegetables and fruits, commonly consumed agriculture products in Korea, were analyzed for their α-carotene, β-carotene, and β-cryptoxanthin contents as provitamin A. The beta-carotene content (㎍/100 g) was high in a few green leaf vegetables such as coriander (5,924.07), gegeol radish leaf (5.855.72), and curried mallow (5,138.01), while α-carotene and β-cryptoxanthin contents were not detected. The β-carotene in 8 kinds of 20 general vegetables was detected in the range of 214.06~1,437.67 ㎍/100 g, while α-carotene was detected at 460.17 ㎍/100 g in only old pumpkin. The β-cryptoxanthin was detected in the range of 106.55~315.49 ㎍/100 g in Japanese elm, watermelon, white cucumber, and lettuce. However, carotenoids were not detected in 10 kinds of agricultural products including oriental melon, potato, etc. In fruits, the beta-carotene contents ranged from 165.72~3,997.39 ㎍/100 g, showing maximum value in apple mango and minimum value in persimmon. The β-cryptoxanthin was detected at 232.22 ㎍/100 g in only passion fruit, while the α-carotene was detected at 77.25 ㎍/100 g in only darae. Thus, based on the analyzed results of carotenoids of agriculture products consumed or cultivated in Korea, and it was found that green leaf vegetables comprise high beta-carotene overall.

Background and objective: Urbanization caused a reduction in urban green space and a lack of community spaces. An attempt to solve these problems, urban gardens, have become popular and are currently being implemented in various downtown areas. However, urban gardens have some inadequate aspects from a visual or landscape perspective. The goal of this study was to examine the possibility of an aesthetic and productive garden space by introducing cultivation methods through the planting system design process. Methods: The design process using plants was classified and presented to suggest the importance of the landscape and aesthetic value. An urban garden space was designed according to the perspective of 'production scenery' and 'participation aesthetics'. According to the characteristics of the plant, urban gardens were divided into vertical type (corn, millet, sorghum), climbing type (kidney bean, cucumber, bitter gourd), and runner type (melon, watermelon, peanut). After classifying plants according to the shape of the root, the structure supporting climbing was installed and the crops were cultivated in an upright form with a tunnel. Results: In the designed cultivation, each crop cooperates, without invading each other's space. Compared with the conventional cultivation, there was little difference in production, and management was made more convenient since weed outbreaks were effectively suppressed while runner type crops cover over the land's surface. Since the positions of each crop are clearly distinguished, the aesthetic value is improved by offering a sense of rhythm with a balanced design. Conclusion: The results suggest that the cultivation methods through the plant system design process have aesthetic as well as productive value, and the design using plants, an infinite living resource, could lead to an expansion of the design field. Moreover, it would enable a sustainable symbiosis between industry and environment. There is potential for the design industry to make significant progress through collaboration with agriculture, horticulture, and landscape architecture.

BACKGROUND/OBJECTIVES: The purpose of this study was to establish a fruit-cooking method suitable for older adults with masticatory dysfunction. MATERIALS/METHODS: Five types of fruits were selected to make fruit jelly and puree: apple, sweet persimmon, mandarin, Korean melon, and watermelon. Recipes were selected based on the Korean Industrial Standard (KS) for senior-friendly foods (KS H 4897), which classifies foods into 3 levels (L1-L3) based on their hardness and viscosity. RESULTS: In South Korea, senior-friendly foods are classified into 3 stages based on their hardness. Stage 1 is for foods that are able to eat with teeth (hardness greater than 50,000 N and less than 500,000 N), Stage 2 is for foods that are able to eat with gums (hardness greater than 20,000 N and less than 50,000 N), and Stage 3 is for foods that are able to eat with the tongue (hardness less than 20,000 N). As a result of measuring the hardness by varying the shape of the fruit, it was found that nearly all fruits could be eaten fresh by chewing with the teeth (L1) but did not meet the KS for mastication using the gums (L2) or tongue (L3), so the cooking method was selected as fruit jelly and fruit puree. Only sweet persimmon, which had a hardness of 61,624-496,393 N, was not suitable for consumption in fresh fruit, unprocessed form. Based on their hardness measurements, fruit jellies (27,869 to 36,343 N) and fruit purees (315 to 1,156 N) met the L2 and L3 requirements, respectively. The viscosity results of all fruit purees met the L3 requirement. CONCLUSION: These results offer a simple cooking method to prepare texture-modified fruits suitable for safe consumption by older adults living with masticatory difficulties in general households and nursing facilities.
