This study examined importance and performance of urban agriculture education program of the trainees who attended urban agriculture education, and suggested reformation of urban agriculture instructor course of Gyeonggi Provincial Agricultural Research & Extension Services by IPA models. The investigation was done on October 7, 2011. The subject was 40 trainees of urban agriculture instructor course of Gyeonggi Provincial Agricultural Research & Extension Services. The study suggested reformation of urban agriculture education program based on the findings as follow: Firstly, the instructors should teach trainees not theoretically but practically to let the trainees make use of learning at urban agriculture. Secondly, teaching material that is not theoretically but practical enough to apply it to actual urban agriculture should be supplied. Thirdly, urban agriculture education should be done not theoretically but practically considering its characteristics. Theoretical contents have been already included in teaching material, and practice oriented education should be done to let trainees put theory into practice on-the-spot. Practice oriented education should be supported in the planning future education. In addition future urban agriculture education program should consider importance as well as practice of educational contents, lecturers, operations and facilities.

The purpose of this study is to develop the teaching competency tool of university teachers with responsibility for college education and analyze the need for change. We have developed teaching competency to strengthen the competencies required for university professors' responsibilities and community activities in and out of universities and the contents validity was examined from 24 experts. The developed tools were used to diagnose the 83 teachers of K university in Chungcheongnam-do, and to derive basic competence, educational practice competence, and community competence through exploratory factor analysis and confirmatory factor analysis. The teaching competencies include 'Understanding of college education', 'Educational philosophy and attitude', 'Teacher attitude', 'Analysis design', 'Instruction execution', 'Guidance management', 'Evaluation feedback', 'Academic convergence', 'Sympathy learning culture', and 'Global sharing'. The results of the paired t-test and the analysis of the need for change through the analysis of Borich coefficient analysis were as follows: Understanding of university education (4th rank), analysis design (5th rank), instruction execution(2nd rank), empathy learning culture (1st rank), and global sharing (3rd rank). The competence of university teachers is not only the ability to practice teaching, but also the ability to understand university education and to empathize and share with the members of the university community. In the future, the university should actively develop and provide ongoing support programs to strengthen the capacity of professors.

공공수역 수질오염 관리에 있어 비점오염원 관리의 중요성이 크게 부각되고 있다. 새만금호 유역은 농경지비율이 40%로서 넓기 때문에 농업비점오염 관리가 중요하다. 농업비점오염 저감을 위한 기법 연구는 국내에서 그 간 상당 수준으로 진행되었지만, 그 기법을 실행할 주체인 농업인이나 지역주민의 역량이나 농업비점오염의 인지도에 대한 연구는 부족한 실정이다. 본 연구는 새만금유역에서 농업비점오염과 관련된 주체들 간의 정보의 소통과 흐름에 대하여 분석해보고, 또한 농업오염 교육 전후에 있어서 지역주민과 농업인의 농업비점오염에 대한 인식도와 교육효과에 대해서 살펴보았다. 먼저, 농업비점오염과 관련된 주체들 간의 지식흐름은 매크로레벨 즉, 정책입안자, 전문가 레벨에서 관련정보가 정체되어 있었고, 실제 농업비점오염 관련 저감 기법이나 정책을 실행하는 주체인 마이크로레벨의 농업인과 지역주민, 이를 지원하는 시군 공무원, 지역전문가 등 매소레벨을 지원하기 위한 정보로 가공 전달되지 못하고 있었다. 농업부서와 환경부서 사이의 농업비점오염에 대한 인식도의 차이가 크게 나타났으며, 특정 분야를 중심으로 활발한 소통이 있는 반면, 정보의 의도적 차단, 자기조직의 대응을 위한 형식적, 임시적 소통이 이루어지고 있었다. 귀농인과 친환경농업인에 대한 교육을 통하여 농업비점오염에 대한 인식도는 교육 전 38.1%에서 교육 후 100%로, 교육 후 농업비점이 오염원이라는 인식도도 친환경농업인 91%, 귀농귀촌인 78%로 응답하였다. 농업비점오염원 관리가 수질개선에 미치는 효과에 대하여는 친환경농업인은 5점 만점에 3.67점, 귀농귀촌인은 4.05점, 농업비점오염원 관리가 필요한지에 대하여 친환경농업인은 4.05점, 귀농귀촌인은 4.09점으로 두 집단 모두 농업비점오염원 관리가 필요하다고 응답하였다. 반면, 친환경 농업은 저감기법의 오염 저감 효과는 높게 인식하였지만, 직접 실행해 볼 의사는 3.4점, 저감 기법을 주위에 소개나 권고할 의사는 3.5점이었다. 또한, 실행 가능한 저감 기법으로는 퇴액비 사용, 완효성 비료사용, 녹비작물재배 등의 순이었다. 저감기법이 어렵다고 응답한 이유는 복잡할거 같다, 귀잖을 것 같다, 추가비용으로 손해, 저감효과 신뢰성 부족, 농업은 오염원이 아니다 등으로 나타났다. 이상의 연구결과를 살펴볼 때, 주체들 간의 정보와 지식흐름을 이어줄 중간조직의 필요성과 농업인의 인식의 변화가 행동의 변화로 이어질 수 있는 교육?홍보 기법과 농업인의 수용성이 높은 저감기법의 개발과 보급이 필요함을 시사하였다.

This paper aims to derive success factors that successfully lead an artificial intelligence (AI) project and prioritize importance. To this end, we first reviewed prior related studies to select success factors and finally derived 17 factors through expert interviews. Then, we developed a hierarchical model based on the TOE framework. With a hierarchical model, a survey was conducted on experts from AI-using companies and experts from supplier companies that support AI advice and technologies, platforms, and applications and analyzed using AHP methods. As a result of the analysis, organizational and technical factors are more important than environmental factors, but organizational factors are a little more critical. Among the organizational factors, strategic/clear business needs, AI implementation/utilization capabilities, and collaboration/communication between departments were the most important. Among the technical factors, sufficient amount and quality of data for AI learning were derived as the most important factors, followed by IT infrastructure/compatibility. Regarding environmental factors, customer preparation and support for the direct use of AI were essential. Looking at the importance of each 17 individual factors, data availability and quality (0.2245) were the most important, followed by strategy/clear business needs (0.1076) and customer readiness/support (0.0763). These results can guide successful implementation and development for companies considering or implementing AI adoption, service providers supporting AI adoption, and government policymakers seeking to foster the AI industry. In addition, they are expected to contribute to researchers who aim to study AI success models.

The detection algorithm for loss of balance had three main parts: one for processing data, another for constructing an internal model, and a third for detecting the loss of balance. The part related to the internal model is the most important part of the algorithm. The purpose of this study is to evaluate the effect of variables associated with the internal model on the success rate of the algorithm. The internal model depends on the type of linearization adopted and the operating period of the algorithm. The design variables were evaluated by performing sensitivity analysis of the variables of the internal model in order to obtain the success rate of the algorithm. The results showed that the most sensitive variable was the period and the period of 0.3 s yielded the highest success rate of 97.1%. Further, the ranges of the design variables that can facilitate a success rate of over 95% are presented.

This study developed a model to evaluate the quality management system of a medical device manufacturing company, and applied it to medical device manufacturers to understand the impact on business performance in response to international regulations and industry's change. This study prepared preliminary items, defined four (4) major factors (Plan-Do-Check-Act) that consist of the evaluation layers and items per category according to prior research review and expert interview, and calculated the weight and importance using AHP. The study results showed that responsibility & authority and quality objective in Planning Category, product-related requirement and R&D in Doing Category, Measuring and monitoring in Check Category, and review of meeting Regulatory and regulation in Action Category are relatively more important factors. The evaluation model developed based on the calculated weight and importance to business performance was applied to medical device manufacturers to investigate and analyze the implementation level of QMS and its impact on business performance according to each category. Most medical device manufacturers to be studied showed a reasonable level of QMS and effective business performance. Almost all the evaluation layers and items in the four (4) factors had a significant influence on business performance. Although the medical device quality management system is aimed mainly at license acquisition, it is important that management environment factors not related directly to licensing and authorization are important to business performance, and it is effective when these factors are integrated and operated within and outside the manufacturer.

The Null Pointer Dereference vulnerability is a significant vulnerability that can cause severe attacks such as denial-of-service. Previous research has proposed methods for detecting vulnerabilities, but large and complex programs pose a challenge to their efficiency. In this paper, we present a lightweight tool for detecting specific functions in large binaryprograms through symbolizing variables and emulating program execution. The tool detects vulnerabilities through data dependency analysis and heuristics in each execution path. While our tool had an 8% higher false positive rate than the bap_toolkit, it detected all existing vulnerabilities in our dataset.

Importance-performance analysis (IPA) is a simple and effective technique that can assist practitioners in prioritizing customer attributes to enhance service quality and visitor's satisfaction. The purpose of this study is to use the IPA-Kano model to examine the correlation of visitor's satisfaction and management matters and deduce the management priority. It classifies 14 visiting satisfaction attributes into basic factors (forest environments and staff/information center), performance factors (the natural landscape, trail facilities, forest status, easy access, and historical and cultural resources), and excitement factors (the value of natural monument, educational experiences, and entrance fee) to select the management priority according to the achievement (satisfaction). The management priority according to the performance is staff/information center > easy access > forest environment > trail facilities, historical and cultural resources, forest status, and natural landscape > entrance fee and educational experience > value of natural monument. By considering their performance, it further identifies development priorities for visitor's satisfaction improvement. These priorities allow local governments to deploy scarce resources to improve satisfaction.
