정부의 수입자유화 정책의 근본취지에는 반대의견이 없었으나, 그 시기와 자유화의 폭을 놓고 시차를 두지말고 대폭 개방하자는 경제기획원 재무부측 주장과, 서서히 단계적으로 실시해야 한다는 상공부안이 맞서 왔으며, 기획원측의 정책을 지지하는 한국개발연구원과 상공부측의 정책을 지지하는 한국산업경제연구원의 대리전쟁이 치열한 것도 따지고 보면 업계에 미치는 영향이 너무도 크기 때문이다. 그동안 원료를 생산하는 농업분야에서는 줄기차게 침묵으로 일관해 왔었으나, 드디어 지난 11일 한국농업경제학회(회장 주종환박사)가 주최가 되어 $\ulcorner$수입자유화와 농업정책의 방향$\lrcorner$이라는 주제하에 동국대학교 동국관501호실에서 심포지엄을 개최하였다. 주제발표자와 토론자로는 우리농업분야의 학자들 외에 이번 수입자유화 정책의 연구담당팀을 주도한 KDI와 국내 주요일간지 경제담당 논설위원들이 참석하여 외부인사들의 농업에 대한 인식이 어떠한가를 엿볼 수도 있었다. 우선 심포지움 제1주제의 내용을 간추려 소개한다(제2. 3. 4 주제는 다음호에 계속).

교육의 새로운 방향은 가상 학교나 WBI와 같은 교육적 활용분야로 확대되고 있으나, e-Learning 상에서 이뤄지는 평가의 응시자에 대한 신뢰 확보는 어려운 상황이다. 기존의 인증이란 사용자가 E와 Password를 타인에게 공개하지 않는 한 본인임을 인증하였다. 하지만 온라인상에서 시험 응시자는 본인의 ID와 Password를 타인에게 알려주어 대리시험이 가능하게 함은 물론 시험문제의 공유 또는 다수의 응시자가 한 곳에 모여 문제를 풀어 감으로서 평가에 대한 신뢰도에 의문을 갖지 않을 수 없게 되었다. 이에 인터넷으로 원격조정이 가능한 PC카메라와 얼굴인식 프로그램 그리고 원격제어프로그램을 이용하여 응시자를 인증함으로써 부정행위를 원천적으로 봉쇄하고, 감독자가 언제 어디서나 웹을 통하여 쉽게 감독할 수 있도록 LMS 기능의 보완이 요구된다. 본 논문을 통해서는 채팅기능을 통한 상호 대화가 가능하고 응시 장면을 동영상으로 압축 저장하여 사후 감독이 가능토록 함으로서 e-Learning상에서의 평가 및 학사관리의 공정성 및 신뢰도를 높일 수 있는 방안을 제시하였다.

In the era of COVID-19 global pandemic, e-learning has become new standards and daily life in the name of 'new normal'. This study developed dialogue e-learning contents as opposed to monologue e-learning which is unidirectional and instructor centered and conducted qualitative user experience evaluation of dialogue e-learning contents. A total number of 20 adult students participated and were individually interviewed. Qualitative data analysis was performed. The findings include students' positive perceptions of dialogue e-learning contents such as empathy for various ideas and new format. With regard to personal preference, 55% of participants preferred dialogue e-learning contents because it enables them to focus and share real experiences. Meanwhile, in terms of learning effects, 60% participants selected monologue e-learning contents and mentioned adequate explanations of concepts and explicit information delivery. Based on the results, suggestions on the design and development of dialogue e-learning contents were presented.

The jujube is an important fruit tree species in Korea. Traditionally, classifications of jujube cultivars have been based on morphological characters; however, morphological identification can be problematic because morphological traits are affected by environmental conditions. Therefore, DNA markers are now being used for the rapid and accurate identification of plant species. Inter-simple sequence repeat (I-SSR) is one of the best DNA-based molecular marker techniques, which is useful for studying genetic relations and for the identification of closely related cultivars. In this study, 5 Korean jujube trees and 1 jujube tree imported from China were analyzed for 16 I-SSR primers. Amplification of the genomic DNA of jujube cultivars by using I-SSR analysis generated 100 bands, with an average of 6.25 bands per primer, of which 45 bands (45%) were polymorphic. The number of amplified fragments with I-SSR primers ranged from 2 to 13. The percentage of polymorphism ranged from 10% to 100%. I-SSR finger printing profiles showed that 'Boeun jujube' and 'Daeri jujube' had characteristic DNA patterns, indicating unequivocal cultivar identification at molecular level. According to the results of clustering analysis, the genetic similarity coefficient ranged from 0.68 to 0.92. 'Boeun jujube' and 'Daeri jujube' were divided into independent groups, and 'Bokjo jujube', 'Geumseong jujube', 'Wolchul jujube', and 'Mudeung jujube' were placed in the same group. Therefore, I-SSR markers are suitable for the discrimination of 'Boeun jujube' and 'Daeri jujube' cultivars.

Recommendations of ITU-T and ISO stipulate the managerial abstraction of static and dynamic characteristics of network elements, management functions as well as management communication protocol. The current recommendations provide the formal mechanism for the structural parts of managed objects such as managed object class and attributes. But the current description method does not provide the formal mechanism for the behavioral characteristics of managed objects in clear manner but in natural language form, the complete specification of managed objects is not fully described. Also, the behaviour of managed objects is affected by their temporal and active properties. While the temporal properties representing periodic or repetitive internals are to describe managed objects behaviour in rather strict way, it will be more powerful if more dynamic temporal properties determined by external conditions are added to managed objects. In this paper, we added dynamic features to scheduling managed objects, and described, in GDMO, scheduling managed objects that support dynamic features. We also described behaviour of managed objects in newly defined BDL that has dynamic temporal properties. This paper showed that dynamic temporal managed objects provide a systematic and formal method in agent management function model.

A measure of managerial ability was derived using DEA, a measure of management efficiency, and the correlation coefficient between discretionary accrual and non-discretionary accrual, net income and operating cash flow standard deviation was used as a proxy for income smoothing. verified. In addition, the manager's compensation was used by taking the natural logarithm of the cash compensation per manager. The analysis results are summarized as follows. The analysis period for hypothesis testing is from 2004 to 2017, as a result of the hypothesis analysis of the correlation with the level of manager's compensation, it was suggested that the income smoothing behavior decreased the performance-based compensation and increased the performance-controlled compensation. This can be said to be the result of indirectly confirming that additional compensation is differentially paid for income smoothing. This study has a contribution to the study by empirically analyzing whether income smoothing affects the relationship between managerial ability and managerial compensation. However, although a number of previous studies empirically analyzed that there are upper and lower bounds for manager compensation, there is limitations that could not be analyzed for asymmetric compensation due to income smoothing is expected to expand.

With the proliferation of electronic commerce, online transactions have become a norm. Its enormous potential, however, can be truly realized if consumers feel comfortable facing invisible sellers over the Internet, a virtual business channel. Trust has been identified as a key component in many e-Commerce studies. The purpose of this study is to find out which factors play a major role in building buyer trust and how the build-up trust affects buyer's purchase intention in online used car transactions. Based on the information asymmetry, TAM (Technology Acceptance Model), and the trust theory, our research model includes factors such as a buyer's propensity-to-trust, institutional characteristics (inspection and warranty policy), word-of-mouth referral, perceived size, and perceived benefits as independent variables. The model also includes trust as a mediate variable, purchase intention as a dependent variable, and perceived quality risk as a moderate variable. The research model is tested by analyzing 448 sample data gathered from used car websites. The result shows that the trust has significant effects on the online purchase intention, and institutional characteristics have been identified as one of the most significant factors for trust building in used car websites. For those who perceive quality risk high, actual purchasing behavior occurs only when they have trust on the used car websites, indicating that trust plays a vital role as a mediate variable. This study suggests that buyer trust on the used car websites is important to increase buyer's online purchase behavior.

Most peoples are used to prefer to view the video contents rather than the other contents since the video contents are more easy to understand with both their eyes and ears. As the wide spread use of smartphones, the demands for the contents services are increasing rapidly. To promote the contents business, it's important to provide security of subscriber authentication and corresponding communication channels through which the contents are delivered. Generally, symmetric key encryption scheme is used to protect the contents in the channel, and the session key should be upadated periodically for the security reasons. In addition, to protect viewing paid contents by illegal users, the proxy authentication should not be allowed. In this paper, we propose biometric based user authentication and one time key generation models. The proposed model is consist of biometric template registration, session key generation and chanel encryption steps. We analyze the difference and benefits of our model with existing CAS models which are made for CATV contents protection, and also provides applications of our model in electronic commerce area.
