The purpose of this study was to estimate the nutrient intake, dietary habits, and body indices among preschool children. The study subjects were 166 kindergarten children, aged 4 to 6 years. A measurement of the weight, height, chest circumference, and head circumference of the children was conducted. The general home environment and factors related to the eating habits of children were collected using a questionnaire that included information about physical activity, outdoor playing time, television watching, family income, and parents education and occupations. Underweight, overweight were defined based on a value of less than 110 and more than 140 on the Rohrer Index, or less than 90 and more than 120 on the weight-length index (WLI). The average Rohrer and WLI for the preschool children were 14.3 $\pm$ 23.2% and 104 $\pm$ 13.5%. Using the WLI, 12.7% of the preschool children were underweight 62.6% were normal, and 24.7% were overweight or obese. On the Rohrer Index, 32.0% of the preschool children were underweight, 34.7% were normal, and 34.1% were overweight or obese. With regard to frequency of regularity of eating breakfast, 2.5% of preschool children skipped breakfast every morning. The risk of being overweight increased in preschool children who had faster eating times. The Rohrer and WLI were negatively related to faster eating times. The average daily energy intake was 1272 Kcal, which corresponded to 79.5% of the Korean RDA. In particular, the average intakes of calcium, iron, and vitamin B$_2$ were much lower than the Korean RDAs for each of those nutrients. Children whose mothers had occupations were at greater risk of decreased nutrient intake than those whose mothers were at home. The data presented in this study confirm that, in preschool children, undernutrition remains the nutritional problem of great concern in Korea, even though Koreans are starting to have worrisome rates of overweight. Therefore, during the early years of life, focus should remain on sustaining Proper growth and development.

최근 다가오는 유비쿼터스 환경에서 RFID 기술은 중요한 위치를 차지할 것이라 예측되어진다. 이로 인해 RFID에 대해 많은 연구가 진행되고 있으며, 물류 유통 뿐만 아니라 금융, 의료, 교통, 문화 등 다양한 분야에서의 활용이 점차 증가되고 있다. 그러나 RFID 시스템에서의 태그와 리더 사이의 통신은 라디오 주파수인 무선통신을 사용하므로 악의적인 제 3자에 의해 식별 정보가 도청될 수 있다. 이러한 도청된 정보는 공격의 기본 정보로 사용되어 질수 있고 이는 사용자의 프라이버시 침해를 가져올 수 있어 사용자들의 RFID 사용을 기피하려고 하고 있다. 이러한 문제점을 해결하기 위해 ID 갱신을 하여 태그의 출력을 다르게 하는 많은 연구가 현재 진행되고 있다. 하지만 기존의 연구에서는 데이터베이스와 태그 사이의 ID 갱신과정에서 ID 동기화를 고려하지 않고 프로토콜이 설계되고 있다. 따라서 본 논문에서는 ID 동기화를 고려하여 RFID 인증 프로토콜을 제안하고자 한다.

Although the number of child loss in commercial facilities has been growing recently, the prevention method for child loss are still lacking in the environmental aspect. This research examines the causes of lost child in behavioral aspects in order to develop a guideline to prevent child loss in U.E.C. The observational study on the behaviors of guardians and children was conducted in the U.E.C that is visited by many customers accompanied with children. Then the results of the observational study were marked on the behavioral maps. After analyzing the behavioral maps, the causes of child loss were determined by classifying into behaviors by age and behaviors by functional space. As a result, when guardian is unable to pay attention to child by doing something else such as making a purchase, or an inquiry, child may lose guardian by going towards the interesting factors or playing around. Moreover, if the spaces related to children are located at the node with high pedestrian density and open structure or the environment that is hard for the guardians to watch over their children, it will be easy for guardians to be inattentive to their children, and get separated from each other.

This study aims to understand why the sales volume and the number of visitors are different in each rural tourism village. The study considered that the management and operation of rural tourism villages is one of the major influencing factors. To prove this, the study determined what factors were related to the management and operation of villages and derived detailed items to evaluate them. In the study, the researchers conducted an in-depth interview and a literature review on the management and operation of rural tourism villages in Yangpyeong-gun. They also performed a case study on the Sumi village, one of the successfully managed and operated villages in Yangpyeong-gun, to determine the detailed items. As a result, seven factors were identified. These factors comprise operation entity, governance, shared vision, leadership, efficient role-playing, marketing efforts, and equity in profit distribution. Based on these seven factors, 85 of the evaluation items were developed. The management and operation scores of 85 items were measured and summed for each of the 21 rural tourism villages. First, 21 villages were divided into two groups by the sales figures to derive items to determine the difference in the mean value of the evaluation scores. Second, an independent sample t-test was conducted for each village at YangPyeong-gun. Third, the study divided the 21 villages into four groups using 46 evaluation items. Finally, the study's researchers clarified some challenges to solve and appropriate management and operation plans considering each type of rural tourism village.

The fashion industry analyzes the value of its essence with ecological design and is expressed as an innovative sculpture using digital technology. Accordingly, this study explores ecological images and digital technologies, categorizes types and derives their meanings through analysis of ecological images shown in modern digital fashion. A literature survey was conducted on ecological images and digital technology as a theoretical background. To analyze the expression type and internal meanings of ecological images, designs with ecological formability were selected and analyzed from related journals, books, and internet sites. The finding are as follows: The expression type was first identified as organic curved garment silhouettes of a non-material liquid with digital retouching. Second, ecological fashion design includes structural shape that applies the silhouette of an organism and patterning of the ecosystem. Third, ecosystems consist of interactions between components of an ecosystem that appear in the interactive type. Accordingly, the internal meanings of ecological images in modern digital fashion are: first, digital fashion can encircle the inherent concepts of nature as organic collections of individuals; second, digital ecological images emphasize a sense of community with coexistence and harmony, playing a complementary role; and finally, the images express perceptual features by providing people with transcendent experiences. This study is significant as it analyzes new formative features based on ecological systems in the digital fashion environment, establishes an aesthetic system through internal meanings, and enhances awareness of human-natural relationships.

The genus Paenibacillus contains a variety of biologically active compounds that have potential applications in a range of fields, including medicine, agriculture, and livestock, playing an important role in the health and economy of society. Our study focused on the bacterium SS4^T (KCTC 43402^T = GDMCC 1.3498^T), which was characterized using a polyphasic taxonomic approach. This strain was analyzed using antiSMASH, BAGEL4, and PRISM to predict the secondary metabolites. Lassopeptide clusters were found using all three analysis methods, with the possibility of secretion. Additionally, PRISM found three biosynthetic gene clusters (BGC) and predicted the structure of the product. Genome analysis indicated that glucoamylase is present in SS4^T. 16S rRNA sequence analysis showed that strain SS4^T most closely resembled Paenibacillus marchantiophytorum DSM 29850^T (98.22%), Paenibacillus nebraskensis JJ-59^T (98.19%), and Paenibacillus aceris KCTC 13870^T (98.08%). Analysis of the 16S rRNA gene sequences and Type Strain Genome Server (TYGS) analysis revealed that SS4^T belongs to the genus Paenibacillus based on the results of the phylogenetic analysis. As a result of the matrix-assisted laser desorption/ionization-time-of-flight mass spectrometry (MALDI-TOF/MS) results, SS4^T was determined to belong to the genus Paenibacillus. Comparing P. marchantiophytorum DSM 29850^T with average nucleotide identity (ANI 78.97%) and digital DNA-DNA hybridization (dDDH 23%) revealed values that were all less than the threshold for bacterial species differentiation. The results of this study suggest that strain SS4^T can be classified as a Paenibacillus andongensis species and is a novel member of the genus Paenibacillus.
