The recent corporate economy, such as the COVID 19 pandemic that has spread all over the world since the beginning of 2020, the acceleration of the 4th industrial revolution, and supply chain management risks triggered by the US-China conflict and the Ukraine crisis, is more serious than ever before. CEOs who have started and managed small and medium-sized enterprises (SMEs) are more concerned than ever about the sustainability of their businesses in this reality. Nevertheless, there were few empirical studies on the factors that influence the intention of SME CEOs to discontinue business. In this study, the perception of the business environment of SMEs (intensity of competition in key business areas, difficulty in manpower management), corporate competency (employee competency, company product or service competitiveness, supply chain and consumer relations, digital competency and technical expertise), and CEO's competency(trust between employees and the CEO, management competency and perceived health status of CEO) on CEO's intention to discontinue business was discussed. As a result of the study, the intensity of competition in the main business field, and the difficulty in manpower management had a positive (+) effect on the intention to discontinue the business, and the employee competency, product (service) competitiveness, digital competency of the company, and the CEO's Health status had a negative (-) effect on intention to discontinue business. The relationship between these influences was found in the order of CEO's health status, product competitiveness, employee competency, digital competency, competitive strength in the main business, and difficulty in manpower management. It was analyzed that supply chain and consumer relations, trust between employees and the CEO, and management capabilities did not significantly affect the intention to discontinue business. On the other hand, business confidence has a mediating effect between the intensity of competition in the main business field, the difficulty in manpower management, product or service competitiveness, digital competency, trust between employees and the CEO, and the management capability and intention to discontinue business was tested. This study had academic significance in that it empirically analyzed factors related to intention to discontinue business targeting small and medium-sized business CEOs. In practice, as it has been found that business environment awareness, corporate competency, managerial competency, and business confidence are factors that influence the intention to discontinue business, if an action ideas that can reinforce this part can be found, SMEs can achieve sustainable growth or it may help CEO find an meaningful exit.

In this paper, we design the CORBA-based Mobile Agent Model (CMAM) which has the capability of the efficient work processing in distributed environment through sensing network traffic and searching the optimal path for migration nodes of mobile agent. In case existing mobile agent model is given various works from user, the network overhead and traffic are increased by increasing of execution module size. Also, if it happens a large quantity of traffics due to migration of nodes according to appointment of the passive host(below node) routing schedule by user, it needs much cost for node search time by traffic. Therefore, in this paper, we design a new mobile agent m()del that assures the reliability of agent's migration through dynamic act on the specific situation according to appointment of the active routing schedule and can minimize agent's work processing time through optimal path search. The proposed model assigns routing schedule of the migration nodes actively using an extended MAFFinder. Also, for decreasing overhead of network by agent's size, it separates the existing mobile agent object by mobile agent including only agent calling module and push agent with work executing module based on distributed object type of CORBA. Also, it reduces the required time for round works of mobile agent through the optimal path search of migration nodes.

본 연구는 방글라데시의 친환경농업 실태와 농업인들의 인식을 바탕으로 친환경농업 개발에 대한 정부의 역할과 정책적 대안을 모색하고자 하였다. 연구 자료는 방글라데시 탕가일 지역의 농업인을 대상으로 유기농가 100가구와 일반농가 100가구를 무작위로 추출하여 설문조사를 통하여 수집되었다. 인구 과밀의 방글라데시 정부는 식량안보를 위하여 지력 저하 및 환경악화를 방지하고자 많은 노력을 기울이고 있다. 즉 지속 가능한 농업개발을 위하여 통합해충관리(IPM), 통합작물 관리(ICM)를 비롯하여 토양의 비옥도 개선, 페로몬트랩이나 자연 천적을 이용한 해충방제 등 다양한 프로그램을 운영하고 있다. 농업인들의 의견 조사에 따르면 친환경농업에 대한 정부의 역할은 긍정적으로 평가하고 있으나 정책이나 관련 프로그램은 아직 부족한 것으로 나타났다. 일반농가인 경우 극히 소수 농가만이 친환경농업을 실행하고 있는데, 이는 관련기술에 대한 지식의 부족과 유기농 비료 등의 자재 부족이 친환경농업을 실행하는데 가장 큰 어려움이라 지적하고 있다. 일반농가의 39%는 유기농업 의사를 보이고 있지만 마케팅시설의 부족과 농사 실패에 대한 두려움 등을 유기농으로 전환하지 못하는 주요 이유로 들고 있다. 일반농가의 일부(17%)만이 정부의 농업교육 프로그램임인 통합해충관리(IPM)과정을 이수하고 있다. 정부의 유기농 정책은 거의 전무하며 NGO들의 지원에 의하여 꾸준하게 진행되고 있을 뿐이다. 따라서 농업인들은 통합해충관리(IPM), 유기농 퇴비, 페로몬트랩이나 자연 천적 등 매우 다양한 농민교육프로그램들을 정부 주도적으로 실시하여야 하며 친환경농업정책을 보다 명확하게 규정하기를 요구하고 있다. 비교적 젊고 교육수준이 높은 소규모 농업인들이 유기농에 적극적임을 알 수 있다. 유기농의 평균 농지규모는 0.246ha, 유기농 평균 경력은 7.63년, 일반농가대비 농가수입은 11.4% 높게 나타났고 비교적 소농들이 높은 수익률을 보이고 있다. 소비자의 신뢰, 마케팅시설, 생산자단체나 조직의 부족 등이 유기농가들의 가장 큰 애로점이 되고 있고, 유기농산품의 표준화를 위하여 정부의 인증제도와 인증기관 설립이 필요함을 지적하고 있다. 유기농을 보다 활성화하기 위해서는 정부 주도하에 마케팅을 비롯하여 교육, 수출 및 각종 장려책 등이 마련되어야 할 것이다.

The aim of this paper is to explore the role played by the endogenous farming organization sustaining rural community's competitiveness. Nulmi-Ri, Chungdo Kun in Kyongsangbuk-do chosen as a case study area is known to be one of the most competitive rural communities, making a living with a peach farming. This community maintains its competi- tiveness by operating a community-based filming organization which was organised in an endogenous way. Most of individual farmers in this community belong to the farming organization and they have cooperative relationships in the processes of production and distribution. In this respect, the exchange and circulation of knowledge, and collective learning, tend to be significantly taken place between the organization members. Based on the experience of the Nulmi-Ri's endogenous farming organization, we propose some constructive comments for rural community development.

According to the changes of the mobile environments, the usage and interest of the Android apps have been increased. But the usage of illegally-copied apps has been also increased. And the transparency and dependability of the app markets has been decreased. Therefore there are many cases for the copyright infringement of app developers. Although several methods for preventing illegally-copied apps have been studied, there may exist possible ways to bypass the methods. Since it is difficult to find out the first distributors of the illegally-copied apps, it is not easy to punish them legally. This paper proposes the method of detecting illegally-copied apps. The proposed detector can detect the illegally-copied apps using odex file, which is created when the app is installed. The detector can also find out the information of the first distributors based on forensic watermark technique. Since the illegally-copied app detector is running as a service on the system server, it is granted that the detector hides from the users. As an experiment result, the illegally-copied app detector takes on average within 0.2 seconds to detect and delete an illegally-copied app.

The purpose of this study was to investigate the needs of middle school students for the practical reasoning in a distance learning environment, to verify the needs differences based on the learner's personal characteristics, student-teacher interaction, and student-student interaction, and to investigate the relationships among student-teacher interaction, voluntary participation of students, and the students' perception of the extent to which practical reasoning is implemented in distance learning. For this purpose, 1,842 middle school students from seven schools in Gyeonggi, Daejeon, Chungbuk, and Sejong areas were surveyed online to investigate the importance of the practical reasoning questions and the how much practical reasoning is implemented in current distance learning. Among them, 1,095 responses were used for final analysis and descriptive statistics, independent sample t-test, one-way ANOVA, and path analysis were conducted. As a result of the study, first, middle school students acknowledged that the practical reasoning was important with the importance average 3.76. Based on the locus for focus model, the priorities of the needs in home economics class were examined, and the values and importance of the problem, and the ramification of the solution were considered to be of high priority. Second, characteristics of middle school students, student-teacher interaction and student-student interaction were found to have positive influence on needs for practical reasoning, while no difference were found by gender or voluntary participation in distance learning. Third, the voluntary participation of students and the student-teacher interaction in distance learning had a positive (+) significant effect on perceived implementation of practical reasoning, yet negative (-) significant effect on needs for practical reasoning.

This paper investigates the issue of efficient reading for sensor data of semi-passive sensor tag. The Cold Chain management system requires complete sensor data without data loss and the short processing time of reading sensor tag data. However, reading the sensed data could be interfered by RF environment such as a jamming, obstacle and so on. This study found that it could lead to loss of the sensed data and takes much time to read it when data loss is occurred. To solve this problem, we propose the transaction processing mechanism that guarantees efficient reading of the sensed data. To do this, we present the technique of dynamic packet size and technique of data recovery to execute read transaction. These techniques improve the reliability of reading operation as well as speed up of read process for the large capacity data. This paper contributes to the improvement of efficient reading of sensed data without any loss of data and large time required.

공공사업의 목적은 사업을 통해서 발생하는 혜택을 인간 및 사회가치 적합하도록 최대한 확산하고자 하는 것이다. 그럼에도 불구하고 당해 사회적 가치를 고려하지 않는 경제 및 정책 범주에서만의 분석은 공공사업의 추진타당성에 신뢰저하를 가져오거나 사업추진지역사회의 막연한 불안감(저항)에 효과적으로 대응하지 못하는 문제를 일으키고 있다. 따라서 타당성 있는 사업추진 및 지역사회 저항을 극복할 수 있는 방법발견은 중요하다고 하겠다. 해결방향은 공공사업으로 영향 받는 당해지역에서의 경제(정책포함)외적인 제약조건까지 파악하여서 전반적인 사회경제적가치(시장가치)를 재발견해 가는데 있다. 그것은 공공사업의 예비타당성 평가시에 잠재적으로 부딪힐 저항이나, 개발이후에 발생할 수 있는 확산가치까지도 대상에 포함시켜야 한다는 의미이다. 주지하는 바와 같이 잠재적 가치는 경제적 요소에서만 발생하기 보다는 당해지역의 사회문화적 잠재성 극대화에서 나온다. 지금까지의 계획수립과정은 정부와 전문가집단이 중심이 되어 계획을 수립하고 작성된 계획안에 대해 시민단체, 환경단체 등 이해당사자들이 공청회나 공람을 통해 의견을 제시하는 소극적 프로세스였다. 한편, 대안적 프로세스는 계획수립의 초기단계부터 다양한 이해당사자를 참여시키고 이들을 보조자가 아닌 계획수립의 주체로서 인정하고 협의와 조정과정을 거쳐 합의를 도출함으로써 계획의 정당성을 확보하고 실행가능성을 높이는 방식이 유용할 것으로 사료된다. 본 연구는 미래지향적 가치를 포괄하고 있는 예비적인 사회적 타당성의 평가항목 및 방법을 제시하고자 한다. 이것은 일반적으로 사회영향평가(SIA: Social Impact Assesment)모델을 통해서 공공사업 및 민간사업이 당해 사회에 미치는 영향을 파악하고, 이의 대응방안 마련에 초점을 맞추고 있다. 주요 내용은 공공사업관리방식의 체계를 파악하고 공공사업의 사회적 타당성 및 국내외 적용사례 분석을 통한 시사점 도출과 사회성 검토항목 및 평가방법을 제시한 후, 우리나라에의 적용방안을 검토하였다.

This paper aims to aid a practical evaluation for screening out the design proposais under applying the IRDS system, which is developed a computer aided industrial design system as a computer application system. In this study, the author adopted 3 evaluation methods with criteria which have quantitative and qualitative attributes : the Intuitive Evaluation Methods(X), the Accumulative Evaluation Method(Y), the Benchmarking Evaluation Methods(Z). The results show that the 3 Methods have reciprocal relationships under reliability(r=0.0001). In analysis on the properties of the evaluation methods, the Evaluation Method (X) shows rapidity especially, the Evaluation Method (Y); relativity, the Evaluation Method(Z); importance respectively. The correlation analysis between the evaluation methods makes the null hypothesis denying, then we could adapt the research hypothesis. Therefore the correlation between them has positive relationship, and it shows thicker than the result of the 1st study.
