The purpose of this study was to divide into a few groups of Bibimbabs with distinctive menu patterns and accompaniments from 484 Bibimbab menus of 360 elementary school foodservices around Busan city and Gyeongnam province. The menus were collected from the internet(http://www.kdclub.com) and the home page of elementary schools from December, 2004 to September, 2005. Moreover, Bibimbabs with high frequency were analyzed by seasons and regions to give informations for menu planing and developing in elementary school foodservices. The serving frequency of Bibimbabs was significantly different among seasons, highest in summer and lowest in winter. Kongnamulbibimbab and Bomnamulbibimbab were highest in frequency in rural areas meanwhile, Sanchaebibimbab, and Chamchibibimbab were frequently served in Busan. The basic structure of Bibimbab meal based on main dish, soup, kimchi and one or two accompaniments consisted of 'side dish', 'fruit & beverage', or 'starchy food & dessert'. Thus, most of the Bibimbab meals were composed of 4${\sim}$5 dishes. Five groups of Bibimbabs were suggested by the menu patterns and kinds of soups. Soups, fruit & beverage, and kimchi were included in the menu patterns of nearly all groups of Bibimbab. However, side dishes and strachy foods & desserts were included of excluded according to the groups of Bibimbabs. Some kinds of soups and side dishes were different among the groups of Bibimbab. These results suggest that the cost, avaliable labor and seasonal constraints contributed mainly to the numbers and kinds of accompainments in the Bibimbab meals. However, taste and sensory balance were also considered in the Bibimbab menus in the School Lunch Program.

Comprehensive bans on tobacco advertising and promotion were introduced through tobacco control legislation in Viet Nam, but it has been established that violations of the bans are very common. This study was conducted to explore the trend in violations of bans on tobacco advertising and promotion at points of sale in Viet Nam in the past six years and to explore any differences in the violation situations before and after the Law on Tobacco Control came into effect on 1st May 2013. Quantitative data were collected through observation of violations of the bans on tobacco advertising and promotion at points of sale in 10 provinces throughout Viet Nam in four survey rounds (2009, 2010, 2011, and 2015). Variation in violation prevalence over time was examined by chi-square test using a Bonferini method. Binary logistic regression was employed to identify the factors that may have influences on different types of violation. A level of significance of p<0.05 was used for all tests in this article. The most common form of violation was the display of more than one pack/one carton of a cigarette brand. Violation of bans on tobacco advertising increased while violations on promotion ban and on displaying tobacco decreased through time. Some factors associated with the tobacco advertising and promotion bans included surveyed years, types of points of sale, regions and areas where the points of sale were located. The enforcement of the bans did not improve even after the issuance and the enactment of the Law on Tobacco Control. This suggests that the monitoring and enforcement of bans on tobacco advertising and promotion at points of sale should be strengthened. Penalties should be strictly applied for violators as indicated in the current tobacco control legislation.

Recently, there has been a lot of discussion about the regional pricing of electricity and electricity self-sufficiency. In Korea, power generation facilities are highly ubiquitous and there is an imbalance between electricity production and consumption regions. So it is proposed to charge different price by region, instead of the current nationwide uniform price, and the regional electricity self-sufficiency rate is proposed as a criterion for identifying electricity production and consumption regions. However, many discussions set the spatial unit for measuring electricity self-sufficiency by 17 Si·Do, which needs to be analyzed for its appropriateness. In this study, we analyzed the electricity self-sufficiency rate using 17 provinces and 229 Si·Gun·Gu as the spatial unit. As a result of the analysis, there are 7 and 10 electricity producing and consuming regions at Si·Do level, but 38 and 191 at Si·Gun·Gu level. In addition, although the electricity self-sufficiency rate measurement has the advantage of identifying electricity production and consumption areas in a simple and intuitive way, we points out that it has some problems with the criteria for regional pricing of electricity.

Purpose: The current study was conducted for evaluation and comparison of dietary behavior and food intake in different regions of Lao PDR. Methods: The survey was conducted on 979 people aged 40~59 years old living in 25 urban provinces and 25 rural provinces in four districts (VTE Capital-Chanthabuly, Xaysetha, VTE Province-Phonhong, and Thoulakhom) of Laos. General demographic information, health status, and dietary behavior were surveyed using a questionnaire. Results: The literacy ratio (p = 0.000), education level (p = 0.000), asset ownership level (p = 0.000), and government and private employee ratio (p = 0.000) were higher in urban subjects compared with rural subjects. The mean value of weight (p = 0.000), waist circumference (p = 0.000), and diastolic blood pressure (p = 0.009) and alcohol consumption (p = 0.000), self-rated health status (p = 0.001), and the rate of obesity (p = 0.000) were significantly higher in urban subjects compared with rural subjects. However, the rate of current smoker was significantly higher in the rural group (p = 0.023). Meals are becoming more westernized by higher frequency of eating out, consumption of fatty meat and fried or stir-fried food in urban areas compared to rural areas. Urban subjects had relatively better balanced meals compared to rural subjects whereas they consumed insufficient meals per day and consumed meals irregularly compared to rural subjects. Intake of fruit and milk was significantly higher in urban subjects compared with rural subjects. However, the intake of vegetables was significantly higher in rural areas than urban areas. Conclusion: The result of this study showed that the traditional Lao diet is being replaced by an unhealthy western dietary pattern, which may be a risk factor for increasing development of non-communicable disease (NCD) in Lao PDR. Planning of proper personalized nutritional intervention and education in each area is needed to decrease the health risks of NCD.

To elucidate occurrence patterns of naturalized plants in agroecosystems, we surveyed flora in uplands, orchards and rice paddy fields in middle regions (Gyeonggi-do and Chungcheong-do) of Korea in summer and fall from 2013 to 2015. Our results showed that there are 77 species of naturalize plants in 54 genera and 20 families of vascular plants among total 420 species occurred in the agricultural areas composing 18.3% of naturalized index. Community compositions of both native and naturalized plants were different among agricultural types. We suggested that Cerastium glomeratum Thuill., Bidens frondosa L. and Erigeron philadelphicus L. are capable of dispersal to other regions based on our results with getting to broaden distribution of naturalized plants. The mean naturalized index was the highest in the upland (25.1%) followed by in the orchard (23.0%) and the paddy field (16.1%), while the mean number of naturalized species was the highest in the orchard (21.8 species) followed by in the upland (16.6 species) and paddy field (10.3 species). The numbers of naturalized plants in the orchard were increased along with increasing size of the agricultural land and decreasing ecological area rate. In addition, the number of native species was significantly correlated with the number of naturalized species in the upland. Our results would provide useful information to manage dispersion of naturalized plants in agricultural ecosystems.

A flexuous rod-shaped virus was isolated from Cucurbita pepo leaves showing as green mosaic and puckering symptoms at Anseong, Korea. Based on the biological analysis, electron microscopy, and reverse transcription-polymerase chain reaction (RT-PCR), the virus isolate was identified as Papaya ringspot virus type watermelon (PRSV-W). From biological analysis, the host range of PRSV-W was limited to the families Cucurbitaceae and Chenopodiaceae. Most susceptible cucurbit species, such as Cucumis lanatus, Cucumis sativus, Cucurbita pepo, and Citrullus lanatus, showed symptoms of green mosaic, malformation, puckering, and narrow laminae by infection with PRSV-W. The local lesion were showed on the inoculated leaves of both Chenopodium amaranticolor and C. quinoa. Field survey of PRSV, Watermelon mosaic virus (WMV) and Zucchini yellow mosaic virus (ZYMV), three major viruses infecting cucurbit, was done during 2001 to 2003 on 173 commercial cucurbit cultivating fields distributed over the three regions of Gyeonggi, Gyeongbuk and Jeonnam Provinces where cucurbits are grown in different environmental conditions and cropping patterns. Typical viral symptoms were observed from 107 cultivating fields, and all three kinds of potyviruses were detected from 206 samples out of the 235 samples using RT-PCR. Watermelon mosaic virus (WMV) and Zucchini yellow mosaic virus (ZYMV) are the most widely distributed viruses in outdoor and retarding-culture fields, at an infection rating of 48 and 33 percents, respectively. PRSV was detected from 12 percent of 235 samples. The nucleotide and amino acid sequences of coat proteins (CP) of eight PRSV isolates, collected from several areas including Anseong, were determined and sequenced heterogeneity among the isolates was performed. The CP gene of PRSV showed 88.6~97.3 percent homology in nucleotide sequences and 95.1~99.3 percent homology in amino acid sequences with other PRSV isolates worldwide. The phylogenetic analysis indicated that the Korean PRSV isolates belong to the southern-east Asian cluster.
