The major concern of e-learning environment design is to create and improve artifacts that support human learning. To facilitate effective and efficient learning, e-learning environment designers focused on the contemporary information technologies. Web 2.0 services, which empower users and allow the inter-transforming interactions between users and information technologies, have been increasingly changing the way that people learn. By adapting these Web 2.0 technologies in learning environment, educational technology can facilitate learners' abilities to personalize learning environment. The main purpose of this study is to conceptualize comprehensively constructs for understanding the inter-transforming relationships between learner and learning environment and mutable learning environments' impact on the process through which learners learn and strive to shape their learning environment. As results, this study confirms conceptualization of four constructs by incorporating aspects of design that occur in e-learning environments with Web 2.0 technologies. First, learner-designer refers to active and intentional designer who is tailoring an e-learning environment in the changing context of use. Second, learner's secondary design refers to learner's design based on the primary designs by design experts. Third, transactional interaction refers to learner's inter-changeable, inter-transformative, co-evolutionary interaction with technological environment. Fourth, trans-active learning environment refers to mutable learning environment enacted by users.

This essay questions and attempts to answer why and how Shakespeare set his plays in time and space other than his own England. Bakhtin's concept of chronotope as integrated time-space offers a model of establishing "a historical poetics." Shakespeare's chronotope has been either negated as mere names for transcendental ideas by universalists, or reduced to a "cover" for contemporary England by historicists. Refuting such either/or approach, this essay claims chronotopic dynamics of both/and as Shakespeare's intentional poetics of ambiguity. While Shakespeare clearly wants to build fictional chronotope distant from reality and does so through verbal repetition, character names, alternation of locales and speaking directly to the audience, he also brings in reality through the figure of clowns and the theatrical space of platea. Anachronism and topological errors ensuing from chronotopic collision register desire to produce multiple meanings. Shaped by historical forces such as Renaissance poetics, education, censorship and new geography, chronotopic form itself is a witness of historicity as much as the coded ideological messages New Historicists industriously delve out. Shakespeare's chronotopic dynamism offers the space for dialogue and appropriation to modern readers, a practice no less worthwhile than history lesson.

To solve the problem of insufficient recognition of key nodes in the existing software defect detection process, this paper proposes a key node recognition algorithm based on node expansion degree and improved K-shell position, shortened as SDD_KNR. Firstly, the calculation formula of node expansion degree is designed to improve the degree that can measure the local defect propagation capability of nodes in the software network. Secondly, the concept of improved K-shell position of node is proposed to obtain the improved K-shell position of each node. Finally, the measurement of node defect propagation capability is defined, and the key node recognition algorithm is designed to identify the key function nodes with large defect impact range in the process of software defect detection. Using real software systems such as Nano, Cflow and Tar to design three sets of experiments. The corresponding directed weighted software function invoke networks are built to simulate intentional attack and defect source infection. The proposed SDD_KNR algorithm is compared with the BC algorithm, K-shell algorithm, KNMWSG algorithm and NMNC algorithm. The changing trend of network efficiency and the strength of node propagation force are analyzed to verify the effectiveness of the proposed SDD_KNR algorithm.

Objectives: The aim of this study was to investigate the characteristics of acute poisoning cases admitted to a local emergency department in an urban-rural area. Methods: This retrospective study included all patients with acute poisoning who admitted the emergency department between June 2004 and May 2005. We analyzed the medical records for etiological and demographical characteristics of the acutely poisoned patients. Results: There were 155(1.0%) poisoning cases among 15,457 admitted to the emergency department. Of the admitted cases, 51.0% were female and 49.0% male. The poisoning made a peak in the age range of 30-39 and over 60. The seasonal distribution in poisoning patients suggested a peak in spring(38.1%) and summer(24.5%). The majority of exposures(95.5%) occurred in patient's home, 81.8% were deliberate. The most common agents of acute poisoning in deliberate causes were drugs(p<0.01). All of deliberate cases were suicidal attempts. The most common poisoning cases were pesticides in male, but in female were medications(p<0.01). Overall mortality rate of total cases were 12.9%. The overall mortality rate was higher in male(p<0.05), increasing age(p<0.05) and intentional ingestion(p<0.05), pesticides poisoning(p<0.05). Conclusions: The study forms a foundation for future work on poisoning epidemiology which hopefully will facilitate the allocation of preventive services in order to reduce the incidence as well as morbidity and mortality of toxic exposures.

Aluminum nitride (AlN) thin films were prepared by using nitrogen ion beam assisted reactive radio frequency (RF) magnetron sputtering on the glass substrates without intentional substrate heating. After deposition, the effect of nitrogen ion beam energy on the structural and optical properties of AlN films were investigated by x-ray diffraction (XRD), atomic force microscope (AFM) and UV-Vis. spectrophotometer, respectively. AlN films deposited with $N^+$ ion irradiation at 100 eV show the higher (002) peak intensity in XRD pattern than other films. It means that $N^+$ ion energy of 100 eV is the favorable condition for low temperature crystallization. AFM images also show that surface average roughness is increased from 1.5 to 9.6 nm with $N^+$ ion energy in this study. In an optical observation, AlN films which deposited by $N^+$ ion beam energy of 100 eV show the higher transmittance than that of the films prepared with the other $N^+$ ion beam conditions.

Korean ginseng (Panax ginseng) and American ginseng (Panax quinquefolius) are widely used medicinal plants with similar morphology but different medicinal efficacy. Roots, flowers, and processed products of Korean and American ginseng can be difficult to differentiate from each other, leading to illegal trade in which one species is sold as the other. This study was carried out to develop convenient and reliable chloroplast genome-derived DNA markers for authentication of Korean and American ginseng in commercial processed products. One codominant marker could reproducibly identify both species and intentional mixtures of the two species. We further developed a set of species-unique dominant DNA markers. Each species-specific dominant marker could detect 1% cross contamination with other species by low resolution agarose gel electrophoresis or quantitative polymerase chain reaction. Both markers were successfully applied to evaluate the original species from various processed ginseng products purchased from markets in Korea and China. We believe that high-throughput application of this marker system will eradicate illegal trade and promote confident marketing for both species to increase the value of Korean as well as American ginseng in Korea and worldwide.

결혼이주자는 외국인 근로자나 유학생보다 지역사회에 미치는 영향이 크고 그 영향은 결혼이주자들의 자녀로 인해 계속 증가하게 될 것이므로 중요한 지역연구 대상이다. 그러므로 본 연구는 결혼이주자들의 차별적인 거주지 형성을 가져오는 근본적인 원인을 알아보고자 한다. 외국인 근로자나 유학생의 경우 처음에는 주거지 선택과정이 외생적 비자발적으로 이루어졌을지라도 점차 이주의 시간이 흐름에 따라 자생적 자발적으로 거주지 선택하는 방향으로 변화하는 반면에, 결혼이주자들의 주거지 분리과정은 자발적인 선택이 거의 어려운 상황에서 이주할 뿐만 아니라 이주 후에도 주거지 변동 혹은 선택이 자유롭지 못한 것이 특징이다. 그러므로 결혼이주자들의 차별적 주거지 분리패턴에 영향을 주는 요인들을 지역사회가 선택한 결혼이주자들의 민족적 배경과 관련지어 설명하고자 한다. 국적별 결혼 이주자의 주거지 분포 경향과 분리정도를 고찰한 후 베트남계와 필리핀계 결혼이주여성의 분포패턴을 중심으로 그 민족적 배경과 집중 분포지역의 관계를 알아보고자 한다.

The UGV is one of the special field robot developed for mine detection, surveillance and transportation. To achieve successfully the missions of the UGV, the accurate and reliable navigation data should be provided. This paper presents design and implementation of multi-sensor-based open architecture integrated navigation for localization of UGV. The presented architecture hierarchically classifies the integrated system into four layers and data communications between layers are based on the distributed object oriented middleware. The navigation manager determines the navigation mode with the QoS information of each navigation sensor and the integrated filter performs the navigation mode-based data fusion in the filtering process. Also, all navigation variables including the filter parameters and QoS of navigation data can be modified in GUI and consequently, the user can operate the integrated navigation system more usefully. The conventional GPS/INS integrated system does not guarantee the long-term reliability of localization when GPS solution is not available by signal blockage and intentional jamming in outdoor environment. The presented integration algorithm, however, based on the adaptive federated filter structure with FDI algorithm can integrate effectively the output of multi-sensor such as 3D LADAR, vision, odometer, magnetic compass and zero velocity to enhance the accuracy of localization result in the case that GPS is unavailable. The field test was carried out with the UGV and the test results show that the presented integrated navigation system can provide more robust and accurate localization performance than the conventional GPS/INS integrated system in outdoor environments.
