A Ypsolophid moth Saridoscelis sphenias Meyrick was recorded in 2020 first in Korea, and specimens were collected from Jindo and Wando in Jeonam province from 2016 to 2017. This moth uses host plants such as Pieris japonica (Thunb.) D. Don ex G. Don, Vaccinium bracteatum Thunb. and Leucothoe grayana Maxim. var oblongifolia (Miq.). This species was discovered once in a blueberry orchard in Jeju in August 2014, and since then it has been regarded as not an established species because of no further detection. However, S. sphenias was found again in blueberry orchards grown in vinyl houses in Jeju city and Seogwipo city in 2018 and 2019. Since 2020, this pest has also been found on field-grown blueberries. Hatched larvae first bored into new shoots and fed inside, and the mid-aged larvae escaped from the inside of shoots, attached several shoots with webs, and fed on the leaves in the group. It is considered that S. sphenias will become a severe pest on blueberries; thus, we report the basic life cycle here.

In this study, the symbols and visual expressions employed in the food culture content of official website designed to promote three cities in Korea, Seoul, Jeonju and Jeju, were subjected to semiotic analysis. In this study, it was assumed that these websites reflected the varying perspectives of the people behind the development and management of these routes of Internet communication, and the semiotic choices made in order to exemplify each city's food cultural image. The aim of the study was to analyze the communication strategies of food cultural branding in the terms of the online content regarding Seoul, Jeonju, and Jeju with a focus on the comparative points in these cities' official websites. This study included conducting semiotic content analyses of the aforementioned cities' official web pages in an attempt to determine the food branding strategies used to differentiation and produce more favorable perceptions of these three cities. Building upon the findings drawn from this comparative study, the present work can be used to determine more effective ways of strategically differentiating the images of local food culture associated with these cities from the view of brand communications. This study also demonstrates viable directions for designing web content for a city where the food cultural messages can be delivered in a thoughtful and effective manner.

This study analyzes the conditions and products of internet shopping malls that sell natural dyeing products. In this study, 98 natural dyeing internet shopping malls were selected. The results of this study are as follows. The locations of the internet shopping malls were Gyeonggi-do, Seoul, Jeollanam-do, Gyeongsangbuk-do, Gwang-ju (city), Daegu (city), Busan (city), Gyeongsangnam-do, and Jeju-do. The most frequent dyes of the natural dyeing products were loess, followed by charcoal, indigo, and persimmon. Indigo was most frequently used in Seoul, with loess and charcoal most frequent in Gyeonggi-do. Persimmon, indigo, loess, and charcoal were mainly used in Jeollanam-do, with persimmon and loess in the Gyeongsangbuk-do, and persimmon in Jeju-do. The highest ordered product categories were accessories, followed by adult clothing, interior decoration products, and bedding. The most frequent products were bedclothes, followed by scarves, female shirts, blouses, pillows, female jackets, and vests. Regarding the price of products, 150,000-200,000 won was the highest for the Saenghwal Hanbok, with 10,000-30,000 won for underwear, 30,000-60,000 won for accessories, and 100,000-150,000 won for bedding. Concerning product information, 58.2% of internet shopping malls offer the product size and almost half of them did not show the properties or directions for handling the product. Based on the research results, the problems of the conditions and products of natural dyeing internet shopping mall were derived. The results show that the natural dyes of internet shopping malls lacked regional symbolism, the products were not specialized, and product information was not fully offered to consumers. To solve these problems, the strategies for marketing the promotion of the natural dyeing internet shopping mall were, ‘Using natural dyes from local resources’, ‘Market oriented and specialized item design’, and ‘Offer right product information’.

The purpose of this survey was to assess the nutritional status of preschool children a county of Jeju Island. This study used health examinations results for preschool aged children, performed by the public health center of Pukjeju-gun in Jeju-do for over three years from 1999 to 2001, of children in kindergartens and children homes. The target children totaled 5,990 from the ages three to six. For a control group, 316 children from the nearby Jeju-city areas were included as well. The items of this research included height, weight, and hemoglobin values. 1. The average height of boys from ages three to six were 96.35cm, 102.14cm, 109.94cm, 111.00cm respectively, and girls were 94.96cm, 100.93cm, 108.33cm, 110.54cm respectively. The average weights of boys from ages three to six were 15.42kg, 16.93kg, 19.65kg, 19.67kg respectively, and the weight of girls were 14.90kg, 16.45kg, 18.88kg, 19.50kg respectively. 2. The percentages of children who did not reach 90% of the Korean standard height were 4.3% in boys 4.1% in girls. The percentages of children with less than 80% of the Korean standard weight were 7.6% in boys and 6.8% girls. The percentages of children over 120% of Korean standard weight were 10.4% in boys and 11.4% in girls. 3. As for the obesity level, the percentage of boys under-weighed(under 10% for standard weight for height) were 11.6% and girls, 9.5%, and the percentages of boys and girls with obesity($\geq$20%) were 3.6% and 4.4% respectively. 4. The mean hemoglobin value of boys were 11.83g/$d\ell$ and girls, 11.83g/$d\ell$. These were lower than the value of average normal Korean children (12.5g/$d\ell$). The mena hemoglobin values of the children in Pukjeju-gun were considerably lower than that of the children living in Jeju-city(12.3g/$d\ell$) as well. Anemia of Children of Pukjeju-gun were estimated at 38.1%(male) and 37.2%(female), by using Hemoglobin level(<11.5g/$d\ell$ 5. The rates of children included within the normal range of obesity level in Jeju-city and Pukjeju- gun were boys 80.2%, 71.6% in boys, and 77.4%, 72.4% in girls. The percentage of children living in PukJeju-gun included within the normal range were considerably low. 6. There were no changes in the Body Mass Index (BMI) during the three years from 1999 to 2001, but the percentage of children with anemia significantly increased. Health care for preschool aged children, especially in the rural areas, is very important. Centering on public health centers, it is necessary to systematically promote health care in the rural areas.

Road freezing caused by snowfall during wintertime causes traffic congestion and many accidents. To prevent such problems, we developed, in this study, a system to predict road freezing based on weather forecast data and the freezing generation modules. The weather forecast data were obtained from a high-resolution model with 1 km resolution for Jeju Island from 00:00 KST on December 1, 2017, to 23:00 KST on February 28, 2018. The results of the weather forecast data show that index of agreement (IOA) temperature was higher than 0.85 at all points, and that for wind speed was higher than 0.7 except in Seogwipo city. In order to evaluate the results of the freezing predictions, we used model evaluation metrics obtained from a confusion matrix. These metrics revealed that, the Imacho module showed good performance in precision and accuracy and that the Karlsson module showed good performance in specificity and FP rate. In particular, Cohen's kappa value was shown to be excellent for both modules, demonstrating that the algorithm is reliable. The superiority of both the modules shows that the new system can prevent traffic problems related to road freezing in the Jeju area during wintertime.
