This paper is for studying stress condition of apprentice doctors who were in Oriental Medical Hospital. This study was done on 35 apprentice doctors who were in Kyungsang University Oriental Medical Hospital and Bulgy Oriental Medical Hospital. The Seven-Minute Stress Test of Thomas E. Sttats and 10 questions which were made by the present writer shows the following results.1. The Body stress scale was the highest point. In order of high percent, this shows Whole scale, Mind scale, Situation scale. 2. In comparison of the stress scale of men and women doctors, all the stress scale of women doctors were higher than men doctors. 3. In comparison of the stress scale of Interne and Resident doctors, Whole and Situation stress scale of Resident doctors were higher than Interne doctors, Body and Mind stress scale of Interne doctors were higher than Resident doctors. 4.

This paper presents the practice of multitexturing in the Internet for enhancing the image quality of 3D contents, where the attributes of objects such as textures are dynamically changed. We explain the empirical results of realizing the X3D nodes related with multitexturing in the recent X3D viewers, and discuss the directions for upgrading X3D viewers that satisfy the user requirements and the advanced graphics accelerators.

최근 인터넷 쇼핑몰에 대한 연구는 초기 쇼핑몰 구축설계 기법 및 보안, 인증 등에 대한 관심을 넘어서 인터넷 쇼핑몰의 추진전략에 대한 연구로 확대되고 있다. 그러나 대부분의 경우에 인터넷 쇼핑몰 추진방식에 대한 단편적인 현황을 설명하는 수준에 그치고 있다. 특히, 실재 공간에서의 지원 활동이 차지하는 중요성에 대한 인식이 재평가되고 있으나, 이에 대한 연구의 추진은 거의 전무한 상황이다. 따라서 인터넷 쇼핑몰을 추진하고자 하는 기업이 수행하는 온라인(on-line) 및 오프라인(off-line) 활동의 특성과 이들 간의 균형을 위한 연구의 전략적 중요성이 매우 높다. 이에 본 연구에서는 성공적인 인터넷 쇼핑몰 사업을 추진하기 위한 전략 연구의 일환으로 사례분석을 통해 온라인상과 오프라인상의 균형된 시각을 수립하는 데 도움이 되는 프레임워크를 제시한다.

A virtual shopping mall is like a real-world mall, supports electronic shopping by selling products or services through Interne. Although increasing numbers of products are being marketed on the Web, little efforts has been spent on evaluating what mall is more suitable for marketing electronically and for protecting consumers. Evaluation of virtual shopping malls is regarded as a major task in business-to-consumer electronic commerce. This paper considers the Analytic Hierarchy Process(AHP) method in the evaluation of virtual shopping malls and provides its applications. The AHP is a systematic procedure for representing the elements of any problem, hierarchically. A series of pairwise comparison judgments is performed to express the relative strength or intensity of impact of the elements in the hierarchy. The AHP model hierarchy consists of the four following levels: decision maker, main criteria, sub-criteria, and virtual shopping malls. the main criteria include the state of physical firms, representation of information on the virtual shopping malls, product or service, convenience for shopping, consumer protection, and consumer service. The total number of sub-criteria in the third level is twenty-nine. All decision makers selected belong to virtual shopping mall enterprises, or universities. As a case study, we show the synthesized priority of the five virtual shopping malls that have acquired an E-Trust mark. Finally a sensitivity analysis shows how well each virtual shopping mall performs on each criterion by increasing or decreasing the importance of the main criteria.

Internet provides the useful method to monitor the current states of the machine tool no matter where a personnel monitors it. In this paper, a monitoring method of the torque of the machine tool's spindle induction motor using interne is suggested. To estimate the torque accurately, spindle driving system of an CNC lathe is divide into two parts, induction motor part and mechanical part attached to the induction motor spindle. Magnetizing current is calculated from the measured 3 phase currents without speed sensor used to estimate the torque generated by an induction motor. In mechanical part of the system, some of the torque is used to overcome friction and remaining torque is used to overcome cutting force. An equation to estimate friction torque is drawn as a function of cutting torque and rotation speed. Graphical programming is used to implement the suggested algorithm. to monitor the torque of an induction motor in real time and to make the estimated torque monitored on client computers. Torque of the spindle induction motor is well monitored on the client computers in about 3% error range under various cutting conditions.

As a lot of people have used electronic commerce, many shopping malls have appeared on the Interne and the shopping information in them has been enormous. So, the need for a system to recommend product to customers is on the increase so as to reduce time and efforts for shopping. In this paper, we suppose a Product Recommender System which is constructed by applying data mining techniques to web for files and analyzing customer's action pattern, customer's profile and product purchase data. This system offers convenience that customers can get their desired information easily, by sending e-mail or mail and recommending web pages when they visit a shopping mall.

Mobile internet has been emerged as a key IT infrastructure while mobile internet service equipments such as smart phones have been introduced in this mobile market. These mobile internet services would be more widely spread in shorter period because the wired internet services are already popular in our life and mobile internet services have the typical characteristics that ubiquitous has. This study investigates the research model for mobile internet services based on previous researches and tests it via questionnaire. The findings are that some of features such as joy and sufficiency are statistically significant as expected.

This study investigated the effect of cognitive dissonance that people experience during online communication on face-to-face communication. When people communicate with others on Interne using the comment system, they know that all the people including themselves equally participate in the discussion as one of the many commenters. At the same time, they somewhat distrust other commenters' attitudes because of the Internet anonymity. We name this seemingly contradicting beliefs as cognitive dissonance and examine how these beliefs affect the intention to communicate in face-to-face. Also, the proposed research model includes other factors such as curiosity and the differences in attitudes between online and offline. To verify the hypotheses, a total of 323 comment system users were recruited and show that most of the hypotheses were supported. This study emphasized its implications by examining the reasons when and why people prefer direct communication rather than comment based communication.

This study is to investigate how mobile internet service users recognize that Wibro service providers should be equipped with what type of organizational capabilities. Especially. this stud y, in exploratory point of view, examines the recognition is differed by characteristics of Wibro service users. This study also is to suggest a few of research propositions regarding the relations hips between organizational capabilities and characteristics of Wibro service users from various statistical analyses. To accomplish these research purposes, this study defined characteristics of Wibro service users (sender, age, job) and organizational capabilities of Wibro service provide rs ( accounting/finance capabilities, production/service capabilities, marketing/sales capabilities. research and development/technology capabilities) based on the review of past mobile interne t service related studies. And then, this study performed not only questionnaire survey on latent Wibro service users but also various statistical analyses.

This paper presents an efficient packet loss resilient scheme for real-time video transmission over the Internet. By analyzing the temporal and spatial dependencies in inter- and intra-frames, we assign forward error correction codes (FEC) across video packets for minimizing the effect of error concealment and error propagation from packet loss. To achieve optimal allocation of FEC codes, we formulate the effect of packet loss on video quality degradation as packet distortion model. Then we propose an unequal FEC assignment scheme with low complexity based on packet correction rate, which uses the packet distortion model and includes channel status information. Simulation results show that the proposed FEC assignment scheme gives substantial improvement for the received video quality in packet lossy networks. Furthermore the proposed scheme achieves relatively smaller degradation of video quality with higher packet loss rates.
