  • 현재의 농업에서 농약의 사용은 불가결한 것이다. DDT의 등장으로 농약만능시대의 막이 열린 이래 세계에서 10만종 이사의 농약이 탄생했다. 현재 전세계의 생산량은 매년 1천만 톤을 넘어섰고 일본의 경우 등록되어 있는 농약수는 원체(화합물종류)로서 367종, 상품명으로서는 약 5800 종류가 판매되고 있다. 년간 일본의 농약생산량은 약 60만 톤으로 농약의 수출량과 수입량이 거의 같기 때문에 생산량이 사용량에 상당하는 것으로 본다. 농약의 식품오염의 측면에서 보면, 단위 면적당 세계 제 1위의 농약 사용국인 일본은 시장에 유통되고 있는 농작물에도 상당한 양의 농약이 잔류하는 것으로 본다. 물론 식품위생법에 26종의 농약에 대해 53작물을 대상으로 하는 잔류농약기준이 있지만, 농약성분이 400종 이상이며 산포 대상이 되는 작물은 53작물보다 훨씬 많다. 또한 한 두 종류의 작물밖에 대상이 되지 않는 농약도 많아서 잔류농약기준은 식품의 안전성 확보면에서는 부족한 것이 많아. 따라서 농산물 생산자 스스로가 농약사용기준을 정확하게 지켜주기를 바랄 뿐이다. 한편으로는, 이러한 현실에 비추어서 농약사용이 일상화된 농업자에게 있어 농약으로 인한 건강상의 문제 또한 적지 않다. 농업자의 건강관리 대책의 일환으로 실시하는 건강진단 및 조사에 따르면, 만성적인 질환뿐만 아니라 농약산포작업후에 나타나는 증세(기침, 피부이상, 불쾌감, 두통, 인후염, 구토)를 경험한 작업자는 예방의학적인 견지에서 농업자의 농약폭로실태파악 및 교육을 해오고 있으나 그다지 설득력을 얻지 못하여 보다 확실한 인체내 흡수량을 측정하는 방법을 생각하게 되었다. 즉 뇨중 농약 대사물을 폭로지표로 하는 생물학적 모니터링(biological monitoring)을 시도, 농업현장에 있어서의 그 실증과 유용성에 대한 검토를 하고자 하였다. 농작업 가운데서 가장 위험하다고 보는 농약산포작업 (수동식 분무기를 이용한 하우스작물 및 동력분무기를 사용한 노지작물)을 대상으로 생물학적모니터링을 실시한 결과 업자의 뇨로부터 농약의 체내흡수를 반영하는 농략의 뇨 분비성 대사물을 측정할 수 있었다. 즉 뇨나 혈액등의 생체시료를 이용한 생물학적모니터링의 농약에의 응용은 서구와는 달리 대부분이 규제가 없는 소규모 자가영농으로 정해진 농약사용지침보다 많은 농약을 사용한다거나, 또는 개인의 습관이나 작업환경에 따라 폭로조건이 달라서 실질적인 폭로-흡수의 정도가 불분명한 경우등에도 충분히 대응할 수 있어 농약사용자 개개인의 농약 폭로-흡수의 정도를 분명하게 밝힐 수 있다. 게다가 평가의 결과를 농약사용의 일선에 있는 농업자에게 피드백 하여 주므로서 농약에 대한 인식을 새롭게 하고 농약취급시의 건강장해예방행동을 촉구하는 등의 효과도 높은 것으로 예방의학적인 유용성이 크다고 볼 수 있다.

  • This study investigates normative role model of the journalists under the changing environment. Firstly, this article explores what pressure the new media environment gives to the journalists in their routine of news production and distribution. These are stated from the angle of epistemological, professional and interactive pressure. Next, as a reference for the standard journalism in the age of mass media, the idea of Rhee Young-hee, a late journalist who won respects from many Korean journalists, is studied. His firm belief in the pursuit of hard facts, rigorous investigative writing and expertism are spelt out. Then, this study explores how, in real term, this pressure changes the journalistic value, norm and practices in the newsroom. Ten of Koran journalists are interviewed in order to get their idea about the emerging journalistic standards under the digital environment. From this in-depth interviews, it is conclued that the pursuit of hard fact, investigative writing, expertism of Rhee Young-hee are, nonetheless the change of the media technology, still effective and provide good reference points for the enhancement of the standard of journalism in Korea. However, it is also suggested that the methods to fulfil desirable journalism in the digital age should be different from that of the mass communication age. The interviewees make propose that the journalist, as a network node, news curator or coordinator, should actively interact with the audiences facilitating their enhanced potential as a news 'prosumer'(producer and consumer).

  • In this study, in order to practice the social inclusion of libraries, the related policies currently announced in the 3rd Comprehensive Library Development Plan were examined, and the current status of tasks promoted by central administrative agencies and metropolitan and provincial libraries was examined based on these policies. As a result, first, in terms of active information welfare realization, various programs and services are being implemented to bridge the knowledge and information gap, but it seems that the scope of the target should be expanded in the future, cooperation with related organizations, and infrastructure improvement. Second, in terms of expanding the openness of the space, the expansion of the open space as an open space and the application of universal design are being performed. In the future, it seems that the scope of universal design application should be expanded in consideration of budget investment for continuous space reconstruction and diversity of users. Third, in terms of linking services across boundaries, services and programs are provided to infants and toddlers, children, women, the elderly, the underprivileged, job seekers, and multicultural families. In the future, it seems that the improvement of the service system for the expansion of inclusive services in libraries should precede, and cooperation between related ministries should be made to provide differentiated services. Finally, it is expected that future policy-making tasks for social inclusion should be considered not only for books, programs, and spaces, but also for librarians' education, establishment of cooperative networks with related organizations, and marketing for services and programs.

  • HLW (High Level Radioactive Waste) is one of the problems that must be solved in the countries that implement nuclear power generation. Most countries that are concerned about HLW treatment are considering complete isolation from human society by disposing them deep underground. For perfect isolation, understanding the characteristics of underground rocks is very important. In particular, understanding the characteristics of discontinuity as a path way is one of the first things in order to predict the movement of exposed nuclear species to the surface. In this study, we used 500m underground core samples obtained from granite and gneiss area. The purpose of this study is to understand the characteristics of the discontinuities in each rock type and to analyze the properties of the joints in the underground relative to the surrounding environment. For this purpose, the types of discontinuities were classified and the distribution of each discontinuity were analyzed through visual analysis of the each sample obtained at 500m underground. This study can be used as a basic data for understanding the properties of discontinuities in the rock of the survey area and it can be also used as an important data for understanding the distribution characteristics of discontinuities according to the rock types.

  • The purpose of this study is to verify the mediating effect of job stress between childcare teacher personality and child abuse, and provides basic data on personality education and coping strategies for childcare teachers' job stress. A survey was conducted on 326 childcare teachers working at daycare centers in Incheon, Korea. The collected questionnaires were subjected to regression analysis, multiple regression analysis, and Sobel's Z-test according to the research purpose with using SPSS 20.0. The research results are as follow. First, it was found that job performance, a sub-factor of childcare teacher personality, had an effect on child abuse. Second, it was found that the sub-factors of childcare teacher personality, humanity, creativity and personality, social relations, and job performance had an effect on job stress. Third, it was found that childcare activities, the sub-factors of job stress, and the relationship with parents had an effect on child abuse. Fourth, it was found that childcare activities, sub-factors of job stress, partially mediated between job performance and child abuse, a sub-factor of childcare teacher personality. These findings suggest that in order to prevent and contain child abuse by childcare teachers, specific plan must be actively prepared to improve job performance skills related to childcare teacher personality and reduce the burden of child care activities which is a sub-factor of job stress.

  • Mun Il-pyeong(1888-1939) is famous for a nationalist historian led history into popular style to enlighten the public. This paper aims to overview the characteristic of Mun Il-pyeong's history based on prior studies on Mun Il-pyeong's works. The characteristic of Mun Il-pyeong's history shows us people centric trend based on a struggle of classes. For the people, he insisted that description of history should be easy and scientific for the people who are host of history. And Mun Il-pyeong insisted the harmony of nationalist history and positive history. This was a progressive attitude in writing history at that time. Another characteristic of Mun Il-pyeong's history is that he considered cultural history as important. Mun Il-pyoeng wanted to overcome the ashamed political history by cultural history. In this intention, Korean history was again born proudful by him. Mun Il-pyoeng pursued open nationalism, not ultra-nationalism by connecting with other world. This paper focused on the essential part of Mun Il-pyoeng's history. Many scholars think Mun Il-pyeong focused on Korean modern history or history of foreign relation. But I think Mun Il-pyeong attached importance to Practical Learning, Sirhak in late Joseon dynasty. Because Sirhak contained Mun Il-pyeong's academic intention, Modernism and Culturism dreamed from his youth age. Therefore he led so-called Joseonhak Undong meaning study of Sirhak. Studying Sirhak made Mun Il-pyeong open a new direction Korean modern history have to go.

  • Nowadays, Data-Network-AI (DNA)-based intelligent services and applications have become a reality to provide a new dimension of services that improve the quality of life and productivity of businesses. Artificial intelligence (AI) can enhance the value of IoT data (data collected by IoT devices). The internet of things (IoT) promotes the learning and intelligence capability of AI. To extract insights from massive volume IoT data in real-time using deep learning, processing capability needs to happen in the IoT end devices where data is generated. However, deep learning requires a significant number of computational resources that may not be available at the IoT end devices. Such problems have been addressed by transporting bulks of data from the IoT end devices to the cloud datacenters for processing. But transferring IoT big data to the cloud incurs prohibitively high transmission delay and privacy issues which are a major concern. Edge computing, where distributed computing nodes are placed close to the IoT end devices, is a viable solution to meet the high computation and low-latency requirements and to preserve the privacy of users. This paper provides a comprehensive review of the current state of leveraging deep learning within edge computing to unleash the potential of IoT big data generated from IoT end devices. We believe that the revision will have a contribution to the development of DNA-based intelligent services and applications. It describes the different distributed training and inference architectures of deep learning models across multiple nodes of the edge computing platform. It also provides the different privacy-preserving approaches of deep learning on the edge computing environment and the various application domains where deep learning on the network edge can be useful. Finally, it discusses open issues and challenges leveraging deep learning within edge computing.

  • The purpose of this study is to explore the direction of teaching and learning in the era of science and technology. The conclusion is as follows: From the perspective of new materialism, the direction of teaching and learning first emphasizes the importance of learning experience. Second, a teaching method that emphasizes giving meaning is needed. Third, there is a need to consider various perspectives and backgrounds. The direction of teaching and learning in the era of phenomenology is, first, the meaning and meaning of learning is important. Second, it emphasizes the role of independent learners. Third, diverse experiences must be integrated. Fourth, a flexible approach is needed depending on the environment and situation. Rather than a fixed teaching method, it is necessary to use a variety of teaching strategies according to the situation and needs of the learner. From the perspective of actor network theory, the direction of teaching and learning needs to first embrace a variety of actors. Second, there is a need to understand the role of the mediator actor. Third, there is a need to emphasize the dynamic aspect of the network. Fourth, there is a need to emphasize interaction and giving meaning. Fifth, there is a need to strengthen interaction with technology. Sixth, there is a need to create a non-linear and open learning environment. The direction of society and teaching and learning presented in Trend Korea 2024 considers time as a precious resource in a divided society, and teaching and learning must adapt and develop in a useful direction in a changing environment.

  • Gangneung farm song is important for the ritualistic labortheatricals. Especially, in the theatrical process program, the songsof weeding, such as Haksan Odokkteggi and Ssadae, were alsoincluded to represent the agricultural ritualistic prayer for goodharvest. The use of Gangneung farm song is attractive in termsofthe circumstances. There is no chance of success as a plan simplyfor local events. As a comprehensive art, Gangneung farmsongshould simultaneously revitalize locality, representability andglobality. In this context, three directions are suggested dependingon the development progress. The second direction to the thirddirection are mainly oriented toward government-local authoritycentered support, but, in particular, the third direction should aimtobe an open archive in which the public and the contents prosumercan participate. In the production of the traditional content, OSMUmust be endlessly recreated and spread through 'diversity' and'interrelationships'. The contents utilization was discussed based on the transmissiondetails and analysis evidence of Gangneung Haksan Odokttegi. Thediversification of the way of performing farm song and the folk songs that can induce interest were proposed. Furthermore, basedon the fact that 12 songs classified into 8 work types, there-creation of the contents that focus on the playful aspect of theperforming arts was also proposed. In addition to suggestingthedesirable discourse of the performance groups, the experienceprogram development, education, public relations andcommunication reinforcement based on the narrating principlesoffarm songs, and the development and execution of farmsongprograms based on the tradition and the event demands wereproposed. While mentioning the necessity of value creation, thevitality of performing arts skills that put emotion, imagination, fun, sympathy, and etc. on the original form and the model of farmsongs should be supplemented to Gangneung Haksan Odokttegi. The independent transmission aspect of Gangneung Arirangisalso positive. There are difficulties of reduction of traditionalitydueto the designation, standardized transmission, lack of developmentof voluntary performances, and demonstration-centeredtransmission. Narrowly, we focused on the education andvitalization directions in terms of the capacity building of theconservation council itself. By embodying the essential value of theagricultural literature that farm songs possess, it can bringimpression of all worlds, all lives, communication and sharing, anddraw inspiration from the humanistic view of the world andemotion. The reconstitution of agricultural heritage, theconstruction of a storytelling linked with the concrete objects suchas Beomil National Preceptor, Gulsansa, FlagpoleSupport(Dangganjiju), Seokcheon, Hakbawi rock, and etc., andtheestablishment of fusion type farm song museum were proposed. In terms of culture industry, we requested active support fromtheinstitutions including local governments and various farmsongstorytelling creation projects.

  • In this study, 1,495 cases of computerized data collected as disease entities of oral and maxillofacial injuries among patient visiting S university hospital located in Seoul in 2009 were analyzed and following results were obtained. It was found that the injury incidence in male was greater than in female (1.49:1), it occurred most frequently in the age of 7~14 years old (19.6%), and its most frequent cause was falling down (25.9%). Injuries occurred in other place including beach and open-air (24.7%) most frequently, often developed in anterior teeth (43.2%) and posterior teeth (43.1%), their incidence was relatively higher between 15:00~17:00 (10.4%) and 19:00~23:00 (7.1%) O'clock. In the relationship between causes of the injury and the diagnosis based on the international classification of disease), falling, fall, impingement, violence, traffic accident, sports and own making accident caused most frequently lip and oral open injuries (S01.5), open fracture of tooth (S02.51), close fracture of tooth (S02.50), close fracture of mandible (S02.60), close fracture of tooth (S02.50), respectively. From the above results, it is necessary to understand general characteristics of oral and maxillofacial injuries and to consider their trends for the establishment of systematic complement policies and for the performing safety training and public relations activities.
