Weeds are a major object which is very harmful to crops. To remove the weeds effectively, we have to classify them accurately and use herbicides. As computing technology has developed, image-based machine learning methods have been studied in this field, specially convolutional neural network(CNN) based models have shown good performance in public image dataset. However, CNN with numerous training parameters and high computational amount. Thus, it works under high hardware condition of expensive GPUs in real application. To solve these problems, in this paper, a hierarchical architecture based deep-learning model is proposed. The experimental results show that the proposed model successfully classify 21 species of the exotic weeds. That is, the model achieve 97.2612% accuracy with a small number of parameters. Our proposed model with a few parameters is expected to be applicable to actual application of network based classification services.

Purpose: This study investigated the occupational status and job stress of visiting nurses during the COVID-19 pandemic. Methods: Participants were 151 visiting nurses working in the public health services in Seoul and Gyeonggi-do. The study was conducted using a structured online questionnaire. Results: The average age of the visiting nurses was 49.5 years. A occupational period was 38.4% of the participants had worked for a period of 6-10 years and 34.5% of them had worked for a period of 11 years or more. In terms of employment type, 74.8% had permanent contracts and 13.9% had fixed terms. 93.4% of nurses were working on COVID-19-related work; and 57.6% of them were working more than 50% of their work. Each visiting nurse provided health services for a total of 436.4 cases on average and the per day count was 14.3 cases. The service was provided through home visits or phone consultations. The results of the job stress were relationship conflict (60.92±20.72), job demand (59.05±14.10), job autonomy (57.83±14.63), job instability (45.25±27.37), organizational system (44.97±17.21), workplace culture (42.71±18.00), and inadequate compensation (35.29±18.14). There was a significant difference in job stress according to the proportion of COVID-19 work was 'workplace culture' (p=.023), Job autonomy (p=.053) and Inappropriate compensation(p=.054). Conclusion: In order to provide a stable working environment for visiting nurses and effective public visiting health services during unexpected circumstances, such as the COVID-19 pandemic, it is necessary to promote progressive policies and systemic improvements.

Objectives: The aim of this study was to identify factors influencing communication satisfaction between geriatric caregivers and older adults in urban-rural complex communities. The ultimate goal was to design local community educational programs and policies to enhance communication satisfaction among geriatric caregivers and improve the quality of care services for older adults. Methods: To identify factors influencing communication satisfaction between elderly caregivers and older adults, a survey titled "CCEP: Assessment of Communication Status between Elderly Care Service Providers and Recipients" was conducted from February to July 2020, focusing on rural-urban complex areas. The survey was administered based on providers of elderly healthcare services. The survey targeted 131 respondents involved in providing care services for older adults. The dependent variable of this study was the communication satisfaction reported by elderly caregivers in their interactions with the elderly. The independent variables included perceptions of older adults, factors associated with communication difficulties, and communication efforts. Additionally, gender, working environment, working experience, and the proportion of face-to-face interactions with older adults during caregiving were controlled for the hierarchical multiple regression analysis. Results: The analysis revealed that communication efforts with older adults significantly influenced communication satisfaction (β=.09, p<0.01). However, perceptions of the elderly and communication hindrance factors did not have a significant impact on communication satisfaction among geriatric caregivers. Conclusion: Effective communication between geriatric caregivers and older adults is crucial for identifying and meeting the needs and demands of caregiving services, and it plays a vital role in overall caregiving service satisfaction. To enhance communication skills and satisfaction among geriatric caregivers and ensure the appropriate fulfillment of elderly care needs in the local community, the development of community-centered, specialized health communication programs and other initiatives will be necessary in the future.

In accordance with the educational paradigm that values self-directed creative education, school libraries and public libraries emphasize self-directed learning support through curriculum-linked programs as their main tasks. For self-directed learning, it is essential to provide learner-centered educational knowledge information, and there should be abundant textbook-linked references that can deepen and expand the curriculum reflected in textbooks. This study established KDC-linked information related to unit and cross-curricular learning topics through the analysis of elementary school textbooks and curriculum-linked books, restructured KDC system based on major subjects in the elementary school curriculum, and established a curriculum-linked subject information. Libraries can strengthen support for self-directed creative learning for elementary school students in an online environment by linking library content targeted for each user with elementary school education content focusing on learning topics in the curriculum.

The place of local tax payment has a realistic meaning in determining the jurisdiction of local taxation. In deciding where to pay tax, the benefit principle, beyond the convenience of tax payment and the efficiency of tax collection, should be considered as the core criteria. The benefit principle seems to be well reflected in the payment place of most local taxes. However, in the case of the Local Income Tax that shares the tax base with the Income Tax, the payment places for business income and capital gains of real estate need to be changed from the place of residence to of business and real estate. Since the benefits of local governments' public services contribute to generating income through various activities such as working or conducting business, it is necessary to ensure that taxation is carried out in the benefit areas where such income activities are conducted. This reform seems to alleviate the tax imbalance among local governments to some extent, and certain positive effects are expected in the areas of tax payment and collection.

We estimate consumer price indexes of eight major cities from 1907 to 1939, and then integrate them into a national level one. The data mainly came from the Statistical Yearbooks of the Government-General of Colonial Korea, and if necessary, we supplement them using wages and unit prices of public utility charges which are used as the price of housing and various services. We apply Laspeyres index method, and the composition ratios of consumption expenditure estimated by the commodity flow method are used as weights. The price indexes of 12 item groups as well as aggregate one are also calculated. In case of Seoul, it is possible to calculate the consumer price index from 1907 to 2009, showing a century-long pattern. This consumer price index is critical for measuring the real income and expenditure before the liberation.

Museums are producing new value and being redefined as places that reproduce context, as the process of globalization are being reflected in museum activities. The new additional functions and roles to the traditional mission of museums allow artworks to find potential functions of art archive and meseum. At the same time, the public has faced originality and aura of an artwork by viewing the physical subject. However, with the appearance of a new digital object, the initiative of viewing has moved over from the artwork to the hands of the public. Now, the public does not go to the museum to see an artwork, but has started to adopt to an opposite paradigm of bringing the artwork forward to the screen. Therefore, they are not satisfied any longer with just seeing an artwork, but demand more information about the artworks and reproduce it as knowledge. Therefore, this study aimed to find types and characteristics through definition and range selection of art archive at this point where the value of art archive is enhanced and systematic management is required, and to present record management methods according to art archive structure and core execution function. It especially stressed that the basis of overall art archive definition was in an 'approach' paradigm rather than a 'preservation' paradigm, and embodied various application methods of digitalized art records. The digital object of an artwork was recognized as the first materialization of an actual artwork, and the digital original of an artwork was presented as the core record. Art archive managed under physical and intellectual control were organically restructured focusing on digital original copies of artworks, which are the core record in a digital technology environment, and could be provided to users in forms of various services that meet their demands. The beginning of systematic management of such art records will become a first step to enhance historical value, establish art cultural identity, and truly possess art culture.
