In this paper, we offer a new technique to discover frequent spatiotemporal patterns from a moving object database. Though the search space for spatiotemporal knowledge is extremely challenging, imposing spatial and timing constraints on moving sequences makes the computation feasible. The proposed technique includes two algorithms, AllMOP and MaxMOP, to find all frequent patterns and maximal patterns, respectively. In addition, to support the service provider in sending information to a user in a push-driven manner, we propose a rule-based location prediction technique to predict the future location of the user. The idea is to employ the algorithm AllMOP to discover the frequent movement patterns in the user's historical movements, from which frequent movement rules are generated. These rules are then used to estimate the future location of the user. The performance is assessed with respect to precision and recall. The proposed techniques could be quite efficiently applied in a location-based service (LBS) system in which diverse types of data are integrated to support a variety of LBSs.

Purpose: This study investigated elderly women's health care at doctorless farm villages based on information-about the perception and management of their health. Method: Grounded theory method as mapped out by Strauss and Corbin-was used to record and transcribe open-ended interviews. The data from these interviews were analyzed. Result: We found 18 categories and 28 sub-categories. In data analysis, the core phenomenon was named "movement in pain". Causal condition as essential prerequisites were aging symptoms, bad state of health, comfortable life to live alone, longevity, deficiency of health care resources, and sub-categories of the phenomena revealed acceptance of discomfort, enduring pain, continuity of movability. Elderly women's health-related activities included enduring as it is, movement consciously, applying resources, difficult in using health medical institutions. Family support, economic level, disease condition, support system of community were influenced to their health-related activities. Consequently, the results indicated that they wanted to accept given life, expected easy death. held out remaining life. Conclusion: This study revealed that the most important factor of elderly women's health care was "movement in pain". On the basis of this study, we needed to develop diverse nursing implementation plans for maintaining and improving' movability without pain'.

When a construction company builds a high structure, many piles should be driven into the ground by a hammer whose weight is 7,000 Kg in order to make the ground under the structure safe and strong. So, it is essential to determine whether a pile is penetrated into the ground enough to support the weight of the structure since ground characteristics at different locations are different each other. This paper proposes a visual measurement system for pile rebound and penetration movement including vibration using a high-speed line-scan camera and a specially designed mark to recognize two-dimensional motion parameters of the mark using only a line-scan camera. A mark stacking white and black right-angled triangles is used for the measurement, and movement information for vertical distance, horizontal distance and rotational angle is determined simultaneously

Using the Sunflower movement as a case study, this article seeks to articulate a theoretical framework to evaluate online "free spaces" as tools for political mobilization. To this end, this article conducts a thematic and content analysis of 151 posts on the official Facebook page of the Sunflower movement. Key results uncover four thematic functions among posts - expressive, informative, informative-support, and promotional - that overlap, in which the expressive theme prevails, and two thematic topics discussed by posts - damages by protesters and their ideology of freedom. I conclude that: (1) combining the logistic and thematic dimensions of posts enables a specific understanding of an online free space's political viability and anticipates the campaigns it will connect itself to; (2) the networked nature of the Sunflower movement page prompts the reconceptualization of (i) online free spaces as nodes through which various political campaigns and struggles are thematically connected by a political ideology; (ii) inactivity as a strategy where protest capital and followers accumulate to prepare and empower future mobilizations.

The purpose of this study is to understand the relationship between the environmental movement and voluntary simplicity life style. The results of this study are as follows： First, both voluntary simplicity life style and the environmental movement are concepts which became the center of public interest because of the evil practices appeared in the process of the development of capitalism. Second, the level of consciousness of environment is comparatively high, but the level of the power of execution is comparatively low as a whole. In the case of Korea, people have not yet the mature responsibilities of citizenship. It is very important to enforce different informal educations in order to increase the effectiveness of the environmental movement. Home training based on voluntary simplicity life style is the most important informal education for the purpose of increasing the effectiveness of the environmental movement. Consequently, for the preservation of environment we need to do our best endeavors such as home training based on voluntary simplicity life style, environmental education based on our social and cultural background, and more powerful administrative measures which is administrative support rather than administrative control.

The paper is to argue against the asymmetric CP-V2 analysis of Old English, according to which finite verbs invariably undergo movement into a clause-final T within subordinate clauses and reach the functional head C within main clauses. The asymmetric CP-V2 analysis, first of all, faces difficulty in explaining a wide range of post-verbal elements within subordinate clauses. To resolve the problem, the analysis has to abandon the obligatoriness of V-to-T movement or introduce various types of extraposition whose status is dubious as a legitimate syntactic operation. Obligatory V-to-T movement in Old English lacks conceptual justification as well. Crosslinguistic evidence reveals that morphological richness in verbal inflection cannot entail overt verb movement. Moreover, the operation is always string-vacuous under the asymmetric CP- V2 analysis and has no effect at the interfaces, in violation of the principle of economy. The distribution of Old English finite verbs in main clauses also undermines the asymmetric CP-V2 analysis. Conceptually speaking, a proper syntactic trigger cannot be confirmed to motivate obligatory verb movement to C. The operation not only gets little support from nominative Case marking, the distribution of expletives, or complementizer agreement but also requires the unconvincing stipulation that expletives as well as sentence-initial subjects result from string-vacuous topicalization. Finally, textual evidence testifies that Old English sometimes permits non-V2 ordering patterns, many of which remain unexplained under the asymmetric CP-V2 analysis.

The purpose of this paper is to review critically the validity and relevance of the pan-national language culture improvement movement, Annyeong! Urimal(Hello! Our Language) implemented for the last three years as part of the government-driven projects, and to seek for improvement direction or fundamental reorientation of this movement. In order to accomplish this purpose, this paper firstly points out abstract and conventional aspects of the diagnosis for background and the purpose of projects, and suggests that this movement focuses on verbal abuse rather than language destruction and pays attention to positive aspects of newly rising language use. Then, with reference to main agent, this paper argues that the government must lead actively formation of voluntary nongovernmental agent with indirect financial and institutional support. Thirdly, it is suggested that public language should be the top priority target sphere and the language used by the leaders of society and the older generation should be also included in the target spheres of this movement. Finally, this paper indicates that enlightenment/public relation projects end often in one time events, imposing unilaterally the normative contents, and also emphasizes the importance of survey/research projects and deliberation/evaluation projects.

본 논문은 일제강점기 거국적인 민족운동으로 전개된 3 1운동과 여성독립운동을 세계평화의 시각에 대입하는 데 초점을 두고 있다. 일본에 의해 국권을 상실했던 시기의 거국적인 민족운동으로 전개된 3.1운동은 세계사적 관점에서 보면, 평화운동의 일환이었다. 특히 3 1운동은 민중운동으로서 계층과 지역, 성별의 구분을 넘어선 독립운동이었으며, 그 시대 독립운동이 지향한 독립과 자유에 대해 평화적 견지에서 재해석할 필요가 있다. 첫째, 그 시대가 당면했던 독립의 과제는 시대적 민족적 견지에서의 독립이었으며, 평화운동의 일환이었다. 둘째, 3 1운동에 참여한 여성은 주체의지로 독립운동의 참여자, 실천자로 변화했으며, 독립운동사에서 한 주류로 한국여성독립운동의 맥락을 이어갔다. 셋째, 3 1운동은 국내는 물론 중국, 일본, 러시아, 유럽, 미주 등으로 확산되면서 아시아 약소국이 자유 의지를 발휘하는 데 영향을 주었고, 국내에서는 독립운동의 정신적 저력이 되었다. 이상에서 3 1운동은 세계평화의 관점에서 재인식되어야 하며, 3 1운동과 한국여성독립운동이 평화운동으로 주목받아야 할 것이다.
