블록체인으로 물류부문에서의 플랫폼을 구죽하고 이를 통해 국내외 유관기관 사용자들을 연동하여 정보를 안전하게 공유하고 물류부문에서의 생산성을 도모하고자 하는 노력이 국내외에서 활발하게 진행되고 있다. 관세청의 통관물류 블록체인 플랫폼구축, 삼성 SDS의 젤로에서 딜리버로 이어지는 물류플랫폼 구축, 케이엘넷의 블록체인형 물류입줄항관리 이외에 다양한 프로젝트들이 있다. 해외에서는 머스크와 아이비엠의 블록체인형 글로벌 물류플랫폼인 TRADELENS 프로젝트, 전세계 항만네트워크사업자들의 모임인 IPCSA 에서 추진하는 블록체인형 전자선하증권등을 들 수 있다. 하지만 물류라는 것이 관련 기관들이 워낙 다양하고 이용되고 있는 서류들이 많아서 쉽게 블록체인으로 플랫폼이 구현되기는 어려울 수 있다. 물류부분의 플랫폼은 기술의 문제라기 보다는 업무 처리 및 이해당사자들의 문서호환 및 정보 공유 또는 보호의 문제이기 때문이다. 새로운 기술로 거론되고 있는 블록체인을 효과적으로 잘 이해하고 우리의 물류부문의 경쟁력을 제고시키는 위해서는 블록체인 플랫폼구축에 대해 보다 바른 방법으로의 접근과 시스템구현이 무엇보다 절실하다 이에 국내외 블록체인 플랫폼 구현현황을 살펴보고 이에 대한 문제점 및 대 응방안을 모색하며 미래의 바람직한 플랫폼 구현방안을 제시하고자 한다.

Due to the urbanization, concentrated population, and limited land exploitation in the modern society, the environment surrounding that we live in is getting polluted more and more, and it has become hard even to let urban children experience the nature. This research was conducted to help people recognize the importance of our natural resources through the environmental education of elementary school and to use school's practical open-space for the Indigenous Plants education. The results of this study are as follows : First, the status of a plant utilization in our institutional education : There were 362 species totally of 124 species of Trees, 156 species of Herbs, 63 species of Crops, and 19 species of Hydrophytes which appear in the elementary school text book. Of all, the most frequently appearing species of tree were the Malus pumila var. dulcissima, Pinus densijlora, Citrus unshiu, Diospyros kaki. Second, the effect of plant education using the land around schools : The result of research on the open-space of the 19 elementary schools located in Mapo-gu showed that most of the species planted are the Juniperus chinensisrose, Hibiscus syriacus. Pelargonium inquinans in the order of size, and the plants appearing in text book were grown in the botanical garden organized in 7 schools. Especially most of the Indigenous Plants were being planted in botanical garden, and Pinus densijlora, Abeliophyllum distichum, Polygonatum var. plurijlorum, Liriope platyphylla and so on. Last, the result of this research on recognition of Environment, Planting education and Indigenous plants : It showed that educational necessity of students and teachers about environment and Indigenous Plants was more than 80%. The management of botanical garden was conducted by some teachers and managers. The results of this study suggested that we needed the reconstruction of curriculum, the efficient application of plant education for effectiveness of using school environment and monitoring continually and construction information sources for the better environment education in the elementary schools.

Objective: The objective of this study was to evaluate the association of social support with health status and health behavior. Methods:　This study was conducted with 79 elderly people in Gunja-ri, Dongsan-myun, Chuncheon. We performed face to face interview which was composed of socio-demographic characteristics, social support, health status and health behavior. The association between social support and result variables was analysed by Chi-square test and logistic regression. We used SAS ver9.1 for statistic analysis. Results: Mean age of the study population was 72.0$\pm$7.0, social support score was 14.3$\pm$4.7 with full marks of 20 and 36.25% of the total population were shown to have depression. When the social support score was changed, depression (p=0.0007) and physical exercise (p=0.0312) showed significant difference. The self-rated health status was significantly related to the relationship with family members (OR=0.25, 95% CI=0.07-0.95) and the quality of sleep was also significantly associated to the relationship with family members (OR=0.21, 95% CI=0.06-0.73). The physical exercise was done significantly less in the group without close friends than in the group with many close friends (OR=0.21, 95% CI=0.05-0.94) and the depression was significantly more in the group without community participation than in the group with community participation (OR=4.79, 95% CI=1.62-14.15). Conclusions: Through this study, we could conclude that the social support factors are associated with health status and health behavior. Therefore, to improve the health status of rural elderly, we need to approach to develop social support.

This study analyzed the tooth brushing behavior and oral health status of foreigner immigrant workers and obtained the following results. Statistical significance based on different general characteristics. Gender, educational background, period of stay, health insurance, medical expense coverage, and whether or not one has friends or regular gatherings were significant traits for frequency, while age, marital status, income, and health insurance were traits for part (p<0.05). Statistical significance (p<0.05) was found in marital status and health insurance for time used to brush teeth, period of stay and whether or not one attends a regular gathering for tooth brushing training, and gender, educational background, period of stay, roommate status, medical expense coverage, and whether or not one attends a regular gathering for supplemental oral product usage. The averages of decayed, missing, and filled teeth (DMFT) index and community periodontal index of treatment needs (CPITN) for general characteristics were 6.98 and 3.03 respectively, and gender, roommate status, income, health insurance for DMFT index, and gender, age, marital status, educational background, roommate status, income, health insurance for CPITN were statistically significant (p<0.05). Tooth brushing frequency and part showed statistical significance (p<0.05) for DMFT index based on tooth brushing behavior, while tooth brushing part and time used to brush teeth were significant for CPITN. DMFT index was high at 8.34 for '3 times or more' in tooth brushing frequency, while DMFT index was high at 7.91 and CPITN was low at 2.94 for tooth brushing part. '3 minutes or longer' in time used to brush teeth was the lowest in CPITN at 2.88. As a result of analyzing the correlation between tooth brushing behavior and DMFT index, CPITN, tooth brushing frequency and part in DMFT index, and tooth brushing part and time used to brush teeth in CPITN showed significance (p<0.05). Based on the above results, we must promote the significance of brushing teeth and implement continuous training for correct tooth brushing management to enhance the oral health of foreign immigrant workers.

This paper reviews current status of weed science in Japanese regional agricultural systems based on the 54th Annual Meeting of the Weed Science Society of Japan. About 300 researchers from 5 countries including Korea participated in the Conference and presented 100 papers in research areas. This congress has an purpose to discuss new troubles, findings and results of weed science. Weed science faces big challenges such as increase in herbicide-resistant weeds, gene-flow from transgenic crops, and invasive weeds. Major research topics were invasive weeds and their ecology, allelopathy, weed management in paddy field, weed management in field crops, and herbicide resistance. Weed control and herbicide resistance management in paddy field were a main object of research. To prevent the increase of problematic weeds and to overcome food crisis, the importance of weed-related researches has been raised. Therefore it is expected that various weed management systems and control of herbicide resistant weeds should be studied continuously in the weed science.

The concept of Baekdudaegan(Korean traditional and major mountain system) was conceived toward the close of Silla Kingdom and in the beginning of the Goryeo dynasty. The concept was brought up through the Goryeo dynasty and was completed in the Joseon dynasty. We have to recognize the next two facts to restore the Baekdudaegan concept these days. Firstly, Baekdudaegan is not the highest watershed line but a domain. Secondly, Baekdudaegan is not a set of ridges but a corporate body of a water system and a mountain system. When it comes to fix the management area of Baekdudaegan, it is necessary to make criteria on the basis of traditional ideas and to include natural characteristics considering physical environment. The management area of Baekdudaegan include the third order of stream with the conservation area including the first order of stream. The most important thing in the management strategy is to prevent the damage of configuration of the ground. Baekdudaegan is a symbol of Korea spirit. Therefore, to manage Baekdudaegan wisely is one of ways to lay down the stepping stone of our country's reunification.

In the past, 'Samcheong-Dong'(三淸洞) was the most beautiful place in Seoul. So this place appealed to everyone. Regardless of their position, people of all age and both sexes wanted to go Samcheong-Dong. And in Samcheong-Dong, the temple of Taoism(道敎) that named Sokeokseou(昭格署) hold ritual to Heaven. Many poets wrote poem about this temple. As a result, Samcheong-Dong has the aura of the sacred mood. Because of the breathtaking landscapes, many people meet in Samcheong-Dong, and hold the poetry club. Not only the upper ten, but also the middle class people composed poems and published many books of poem. The image of Samcheng-Dong that our contemporaries must remember is the next three distinctive qualities. In the first, the Korean unique temple of Taoism was located in Samcheong-Dong. Secondly, the house of royal family and the upper ten was adjacent to Samcheong-Dong, so this place has the aura of high culture. Thirdly, many poem was created in Samcheong-Dong, so this place leave a masterpiece of middle class that will go down in literary history.

Recently, as of March 18, 2022, Corona-19 (COVID-19) has 8,250,000 confirmed persons and 11,481 deaths, and has been increasing since the outbreak in 2020. By limiting the number of people and time, we are showing how our daily life changes depending on the number of confirmed coronas. Therefore, in this study, we implemented an algorithm that predicts the number of confirmed people the next day to help minimize damage to the limits of daily life. This algorithm is an algorithm that predicts the number of confirmed persons on the next day using the number of confirmed persons for 3 days. It is predicted by adding the RNN and Dense layers using the Sequential model, and the number of people is subdivided by region. In order to predict the limit, we matched the personnel limit based on the number of fixed persons per day based on Seoul.
