The objective of this study is to identify performance factors in the automatic classification of records by utilizing metadata that contains the contextual information of records. For this study, we collected 97,064 records of original textual information from Korean central administrative agencies in 2022. Various classification algorithms, data selection methods, and feature extraction techniques are applied and compared with the intent to discern the optimal performance-inducing technique. The study results demonstrated that among classification algorithms, Random Forest displayed higher performance, and among feature extraction techniques, the TF method proved to be the most effective. The minimum data quantity of unit tasks had a minimal influence on performance, and the addition of features positively affected performance, while their removal had a discernible negative impact.

The purpose of this research is placed on the development and application of environmental play programs for elementary school students their utilizing the neighborhood learning gardens in their districts to find its effectiveness. The research questions drawn to attain the purpose of the research are as follows. Initially, analyze the contents related to the plant appearing in the textbooks of wise life, science and practical arts of the 7th elementary school curriculum. Secondly, develop a plant utilizing environmental play program targeted towards the 4th grade elementary school students with the results of the textbook analysis as the foundation. Third, apply the plant utilizing environmental play program into the classroom to verify its effectiveness. Based on the conclusion of this research, the following is to be proposed. First, the revitalization of regional environmental education utilizing the various surroundings of the region is essential. Also, the current method of education, which is focused on theoretical knowledge, and being operated in most of the schools need to be changed over to diverse environmental education programs that are linked with the region. For this, an internet based database, information sharing and exchange program centralized around the regional environmental education center needs to be prepared. Moreover, since this research had developed an environmental play program utilizing plants that focused on the 4th grade elementary school students to verify its effectiveness, the development for environmental play programs dealing with various themes for each grades is required. Lastly, although this research has verified the effectiveness in the variables of ecological knowledge, environmental susceptibility, environmental attitude, environmental concern, environmental function and responsible environmental behavior amongst the variables of environmental literacy but there requires a succeeding research considering the variables that haven't been included in this research.

This study aims at choosing indicators to measure the effect of utilizing biotop map, and analyzing its effect by an indicator from the perspective of performer. The Primary performance indicators are made through specialist survey using SMART. As a result, three indicators are chosen: "Discussion of the period of an environmental effects evaluation(reduced effect)", "Plan and execution of environment and ecology plan in an urban development site", "Minimizing ecological damage in an urban development." The result in each indicator is as follows. The indicator of discussion of the period of an environmental effects evaluation(reduced effect), the average reduction rate in statistically meaningful level reduced 6.08% and 11.64% respectively in 2004-2005. In this period, environment information system was established and the reduction effect is shown in this period by reinforcing environment effect estimation using biotop map. As to the indicator of utilizing biotop map in an urban development site, the Seongnam P site case shows that biotop map was used when they set up an development plan. In case of minimizing ecological damage in an urban development, the Gwangjingu G-dong case shows that it was used to appoint preservation sit, and mediate development restrict area. Accordingly, the biotop map utilizing effect is confirmed through core performance indicators and verification of the indicators using SMART. The further research is encouraged to find evaluate indicators and verify the effect quantitatively to increase the use of biotop map.

Information management of products and services in every industries is gaining importance for resource planning and maintenance. In this paper, we analyzed the information classification systems for railway industry. International and domestic classification systems, such as HS, UNSPSC, eCl@ss and ISIC, are reviewed; as a result this paper presents the findings and the various issues. We proposed to-be images in adopting and utilizing the classification systems. Using the integrative information classification systems could make efficient electronic procurement, supply chain management and e-Business of railway services.

예전보다 약과의 접촉이 많아지고 쉬워지면서 집안에 방치되거나 복용을 잊어버린 약들이 더 많아졌다. 이런 약들을 다시 먹으려 할 때는 특별한 주의가 필요하다. 특히나 임산부, 어린이등 취약 계층은 더욱 주의가 필요하다. 이들 모두가 간단하게 이용할 수 있게 사진을 찍으면 약의 이름과 효능, 부작용, 복용방법 등에 대한 정보를 알 수 있는 어플리케이션을 개발했다.

Recently the paradigm of business management has changed. The businesses have restored to ERP or BPR to integrate their information system. But now they are trying to find out a new competitiveness in tacit knowledge of individuals. The creative company has come to put much weigh on the value of their employee′s "non-patternized" knowledge. And this trend has seen a development into a theory of knowledge management in which "non-patternized" knowledge, along with explicit knowledge, is also considered as a source of competitiveness. With the hypothesis that the recognition of the knowledge management and the utilization of the information technology will have influence on the integration of the integrating the information system information system into a new phase, this study carries out a research on the effects of knowledge management and information technology on management achievement. According to this study the distribution of knowledge has an effect on the integration of information system and management achievement. The asset of knowledge, however, has little effect on them. This means that the recognition of the asset of knowledge alone can't affect the management achievement, but when combined with the recognition of the distribution of knowledge, it can have influence on the management achievement. Thus, a company has to enhance the recognition of the distribution of knowledge. And with this, a company can have a business management based on management achievement and the integration of information system utilizing information technology and the recognition of knowledge management. A company has to promote it business achievement by integrating the information system utilizing information technology and recognizing knowledge management.

In this study, we established the process for collecting and utilizing video scripts of disaster site based on public-private partnerships. It is for the purpose of actively utilizing private capabilities in disaster management, and quickly sharing video scripts to identify field conditions. Based on the experience of actual operation of public-private partnerships system in the event of typhoon in 2019, we also derived implications for continuous operation of the process. Results are meaningful in that the government established the process for collecting and utilizing video scripts through public-private partnerships during the initial disaster response phase. And we also confirmed the possibility of spreading positive perception of disaster management organizations. However, there is a limit to the actualization and practical use of performance as an experimental pilot operation in the R&D stage. In addition, for continuous operation of the system, it is necessary to prepare institutional support measures such as organization, infrastructure for operating, programs of education and training, and policy making.
