This study investigated the effect of the delivery service quality of Mongolian online shopping on the customer value, customer trust, and relationship persistence intention of Mongolian consumers. Through this, the purpose of this study is to understand the priorities of the quality conditions of delivery services (accuracy, economy, information, safety, tangibility, etc.) that Mongolian consumers value. The empirical analysis results of this study are as follows. First, the effect of delivery service quality on the intention to continue the relationship showed partially significant results. In other words, economics, information, and safety, excluding accuracy and tangibility, influenced the intention to continue the relationship. Second, the effect of delivery service quality on customer value was partially significant. In other words, accuracy, economy, safety, and tangibility, excluding informativity, influenced customer value. Third, the effect of delivery service quality on customer reliability was partially significant. In other words, economics, safety, and tangibility, excluding accuracy and informativity, influenced customer reliability. Fourth, the hypothesis of customer value on customer reliability was adopted, followed by the hypothesis of customer value on relationship continuity intention. Finally, the hypothesis of customer reliability on relationship continuity intention was adopted.

Purpose - This study examines whether internal control has an effect on stock price informativeness about future earnings. High quality internal control provides continuous assurance for the quality of financial reports, and these future earnings-related information is accurately reflected in the current stock price. Design/methodology/approach - This study collected 12,862 data from 2006 to 2021 in China to make an empirical analysis using the future earnings response coefficient (FERC) and the multiple regression analysis were hired in order to analyze the data. Findings - We find that internal control strengthens the association between current returns and future earnings, indicating that more information about future earnings is reflected in current stock prices. This positive effect exists in both the main board market and the growth enterprise market of China's stock market, especially in the main board market after the implementation of the internal control policy. In addition, we find that the positive effect is weaker for firms that report internal control deficiencies or receives non unqualified internal control audit opinions. The results using earnings persistence yield similar findings, further supporting the results based on the FERC model. Research Implications or Originality - Our tests provide strong evidence that the quality of internal control affects FERC in China stock market.

Jini architecture's Network Plug and Work provides simple and flexible network environment for distributed applications. Through the Jini technology, facilities for dynamically registering and locating mobile agent services can be easily supported, as well as the services useful for activities of mobile agents can be dynamically supported. In this paper, we describe a Jini-based mobile agent system named JMoblet, which provides the basic functions of a mobile agent system such as creation, control, transfer, location and communication among agents. To increase the reliability of the system, it also provides exception handling and persistence of the mobile agent systems for reliability.

In this study, we surveyed 184 participating participants in the golf lesson program. The motivation, self-efficacy, and intention to participate were surveyed. First, the multiple regression analysis of participation motivation and self-efficacy showed that behavior self-efficacy had a significant effect on external manifestation and socialization, whereas maintenance self-efficacy was related to technology development/achievement, enjoyment, A significant influence was found. Second, regression analysis of participation motivation and participation persistence intention showed that only enjoyment factor explains meaningfulness of participation persistence intention. Third, regression analysis of self-efficacy and participation persistence showed a significant effect on both behavior and maintenance factors.

오늘날 이동 에이전트 기술은 네트워크 트래픽을 효과적으로 줄이고, 서버의 인터페이스를 바꾸지 않고 클라이언트의 다양한 요청을 융통성 있게 서비스할 수 있는 기술로 여겨지고 있다. 그러나 대부분의 이동 에이전트 시스템들은 그들 자신의 구조를 적용하고 다른 방법으로 구현되어, 특정 이동 에이전트 시스템에서 생성된 이동 에이전트는 다른 에이전트 시스템에서는 사용될 수 없다. 이러한 문제를 해결하기 위하여 OMG(Object Management Group)는 이질적인 에이전트 시스템간의 상호운용선(interoperability)을 증진시킬 목적으로 이동 에이전트와 에이전트 시스템간의 공통된 개념적인 모델에 대하여 기술한 MAF(Mobile Agent Facilities) 명세를 제안하였다. 본 논문에서는 OMG MAF 명세를 만족하는 자바 기반의 SMART 시스템에 관하여 기술한다. SMART 시스템은 MAF 명세에 따른 이동 에이전트간의 상호운용성을 지원하고, MAF 명세에서 권장하는 보안 모델을 기반으로 한 독자적인 보안 기능을 제공한다. 또한 보다 안정된 에이전트 시스템의 운영을 위하여 자체적인 에이전트 및 에이전트 시스템의 영속성(persistence)과 예외처리를 지원한다.

To detect and recover packet losses over wireless links is very important in terms of reliability in packet transmission. Most wireless communication systems adopt an automatic repeat request (ARQ) protocol operating at link layer. However, it has been constantly addressed that the interaction not harmonized sufficiently between ARQ and TCP rather degrades TCP performance. In this paper, therefore, we propose an improved scheme from the aspect of the interaction with TCP loss recovery mechanism that can be applied to selective repeat ARQ (SR-ARQ) protocol and prove that the proposed scheme improves TCP performance significantly by OPNET simulations.

Purpose: The purpose of this study is to analyze the drinking status and to identify the impacts of depression, temperament, characteristic on drinking status in the vocational high school students. Methods: By using stratified sampling, 416 vocational high school students in Gangwon Do were selected and surveyed through self -administered questionnaires. Data were analyzed by SPSS 12.0 using $x^2$-test, t-test, ANOVA, Pearson correlation coefficient and multiple regression. Results: 88% of students had experienced of drinking. Depression was observed 59.1% of students from light to severe depression score. There was a positive correlation among drinking, the school records, novelty seeking, reward dependence and persistence. Also, there was a negative correlation among drinking, economic status, harm avoidance. The significant predictors of drinking were school records, depression, novelty seeking and persistence. Conclusion: These results suggest that vocational high school students who have the factors identified in this study are regarded as having the potential to drink. The results of this study can provide the information for the development of the health promotion program.

In this study, we have researched for a high-efficiency display with low power, less complicated configuration, and more attractive features than using conventional displays (CRT, LCD, LED, etc.) by manufacturing a propeller display using the POV(Persistence of Vision) phenomenon. After setting the reference point using the Hall sensor, the channel recognition signal and voice recognition signal are transmitted to the display using Bluetooth through the mobile phone application created based on the App program, and the display performs different operations according to the commanded Bluetooth signal. Finally, it was confirmed that the desired information is expressed on the display screen at a motor speed of 1,030 rpm.

J2EE 어플리케이션에서 영속성을 관리하기 위한 데이터 계층에 많은 기술들이 제공되고 있다. 특히 ORM(Object Relation Mapping)을 위해 비영리적이면서도 성숙도가 높은 기술들이 많은 관심을 받고 있다. 그러나 중대형 규모의 어플리케이션에서는 아직 활발하게 적용되고 있지 못한 것이 현실이다. 이것은 새로운 기술 적용에 대한 위험 부담과 기술 자체에 대한 신뢰성이 아직 따라 주지 못하고 있기 때문이다. 논문에서는 대표적인 오픈 소스 ORM 기술인 iBatis와 Hibernate에 대해 알아보고, 적용 전략과 가능성을 살펴본다. 이를 위해 몇 가지 시나리오를 가지고 반응 시간과 메모리 활용을 측정하기 위한 테스팅을 수행하고, 이를 통해 각 기술들이 가지는 장단점을 연구한다.
