  • Screen splitting is one of the fundamental tasks in different methods including video and image compression, screen classification, screen content coding and the like. These methods in turn support various applications in data communications, remote screen sharing, remote desktop delivery to assist teaching-learning, telemedicine, Desktop as a Service etc. In the literature we find systems requiring splitting assumes a fixed size split that do not change dynamically, also there is no analysis why that split is chosen in terms of performance. By doing mathematical analysis this paper first finds the efficient splitting schemes that can be easily automated to make a system adaptive. Thereafter, taking the screen motion detection as a case study, it demonstrates the effects of various splitting methods on motion detection performance. The simulation results clearly shows how classification performances varies with different splitting which will facilitate to choose the best splitting for a specific application scenario as well as making the system adaptive by providing dynamic splitting.

  • Referring to John Irving's 2001 published fiction The Fourth Hand, the publisher commented, "It seems, at first, to be a comedy, perhaps a satire, almost certainly a sexual farce. Yet, in the end, it is as realistic and emotionally moving as any of Mr. Irving's previous novels." In his early six novels, John Irving shows the world suffused with grief and deception. But his novels finally turn out also as a comic and robust novel. The writer's success in achieving this thick description of the contradictory modern world is largely due to his development of the idea of the flawed hero. Despite loss, sadness and abandonment, Irving's heroes maintain classical heroic traits such as intelligence, tenderness, protectiveness, strength, bravery, sense of humor, independence, attractiveness. In this article, I tried to emphasize these graces potent in Irving's heroes as the most attractive and influential device for the writer's consistent popularity among the general public. The cinematization of his four fictions attest to audience's sympathy toward rewarding vulnerability and truthful exaggeration in the depiction of Irving's heroes. By taking full responsibility for their own fate despite having the flaws, Irving's protagonists still appeal to many readers as heroes resilient in a modern chaotic world without losing their graces.

  • Purpose: Venlafaxine and duloxetine have been shown to be effective in the treatment of neuropathic pain disorders. However, knowledge about the efficacy of venlafaxine and duloxetine on burning mouth syndrome (BMS) is still insufficient. The purpose of this study was to investigate the efficacy of venlafaxine and duloxetine on refractory BMS patients. Methods: Twelve refractory BMS patients who were prescribed venlafaxine or duloxetine were included in this study. These patients did not respond to previous administration of clonazepam, alpha-lipoic acid, gabapentin, and nortriptyline. All participants were the primary type of BMS patients who had no local and systemic factors related to the oral burning sensation. The intensities of oral symptoms following venlafaxine or duloxetine administration were compared with those before administration and at baseline. Results: Venlafaxine and duloxetine were prescribed to four and nine patients, respectively. One patient was prescribed both medications in turn. Among them, only two patients showed improvement of oral symptoms without side effects. In the other ten patients, symptoms failed to improve. Six of them reported that the drug was ineffective, and four of them stopped taking the medications on their own due to intolerable side effects, such as insomnia, constipation, drowsiness, dizziness, and xerostomia. Conclusions: Venlafaxine and duloxetine may only relieve oral symptoms in a minority of refractory BMS patients. Further large-scale studies are needed to determine the potential clinical factors that could predict the efficacy of venlafaxine and duloxetine.

  • This paper reports on the results of a parametric study, which examines the effects of varying aspect ratios on the dynamic response of cylindrical silos directly supported on the ground under earthquake loading. Previous research has shown that numerical models can provide considerably realistic simulations when it comes to the behavior of silos by using correct boundary conditions, appropriate element types and material models. To this end, a three dimensional numerical model, taking into account the bulk material-silo wall interaction, was produced by the ANSYS commercial program, which is in turn based on the finite element method. The results obtained from the numerical analysis are discussed comparatively in terms of dynamic material pressure, horizontal displacement, equivalent base shear force and equivalent bending moment responses for considered aspect ratios. The effects experienced because of the slenderness of the silo in regards to the seismic response were evaluated along with the effectiveness of the classification system proposed by Eurocode in evaluating the loads on the vertical walls. Results clearly show that slenderness directly affects the seismic response of such structures especially in terms of behavior and the magnitude of the responses. Furthermore the aspect ratio value of 2.0, given as a behavioral changing limit in the technical literature, can be used as a valid limit for seismic behavior.

  • Recent technological advancements have had a substantial impact on consumer buying behavior. This research aims to determine the factors affecting consumer behavior related to the adoption of self-service technologies (SSTs). The intended findings of this study are expected to contribute to understanding consumer behavior towards the adoption of SSTs taking into account the logic of two main theories in this regard: the Technology Acceptance Model (TAM) and the assumptions of the Behavioral Perspective Model (BPM). This research follows a triangulation approach. Consequently, a number of semi structured interviews were conducted with experts and executive directors from selected SSTs providers in Jordan. In addition, the convenience sampling technique was employed focusing on current (or) previous users of SSTs in the public and private sectors in Jordan using a self-administrative questionnaire (66% response rate). The results confirmed the influence (direct and indirect) of previous experience and personal initiatives and characteristics on consumer intention to use SSTs. In addition, the results indicated the important role of the mediator variables namely: perceived ease of use (EOU), perceived risk (PR), and perceived usefulness (PU) on consumer attitude towards SSTs which in turn will positively affect consumer intention to use SSTs.

  • The paper demonstrates the potential contribution of integrating discursive and affective analytic regimes in framing the study of Southeast Asia. I examine the "emotional possibilities" available to migrants with particular focus on the experience of Filipino domestic helpers in Hong Kong thrown into relief in 2016 by news of maids falling to their deaths while cleaning windows of their employers' above-ground apartments. First, I situate the study in recent calls for Critical Discourse Studies and Migration Studies to transcend foundational methodologies in their respective fields in order to apprehend formerly disregarded aspects of the human condition, including affect and emotion. I then briefly present the debate in the affective turn in social analysis, which has to do with rethinking the attachment of affect and discourse. My own inquiry is premised on the assertion that emotion is multidimensional. I specifically explore the usefulness of taking emotion as "affective-discursive practice" by focusing on an analysis of the appropriation of the victim role by foreign domestic helper employer groups that could be seen in pertinent news reports of selected online Hong Kong newspapers. In the end, I also emphasize the necessity of reflexivity in projects that take affect as central object of inquiry.

  • We have come to the time when we no longer ask why we computerize, but we need to concentrate on how to effectively accomplish the task. Application of computers has been very active in many fields in Korea during the last few years. And yet libraries are rather slow in taking adventage of computers most likely due to the lack of adequate funds and proper understanding of administrators, but also it seems that the majority of librarians are not quite prepared to adopt it. The purpose of this paper is to study the various aspects of computerization of library work, mainly for library administrators and librarians; although they need not understand the electronical and technical aspects of computers, but they should prepare themselves enough at least to be able to make proper requests to computer specialists in relation to what they want to accomplish with computers in order to improve the work of the library. In preparing this paper, not only successful cases of computer application which had been carried out in many libraries of advanced countries have been studied, but also various reasons for failure have been reviewed in order not to make the same mistakes. The paper covers those areas of library work where computers can be applied, such as feasibility, cost effectiveness, planning, implementation and some other aspects of computerization. As a conclusion, two viewpoints need to be discussed. First, each library should work cooperatively with other libraies instead of trying to develop its own computer programs, since we cannot affort to waste financial and technical resources as well as time. Computer applicable library work can be divided and assumed by certain libraries with responsibility to develop turn-key systems applicable to Korean university libraries. In order to carry out this task, there should be complete financial assistance from government, and in turn those libraries shouldf be required to offer assistance to any other interested libaries in Korea. Secondly, library school curriculum should offer such courses where future librarians can learn decision making, business administration and independent thinking in addition to traditional courses. Future librarians as well as those who are already in the profession should prepare themselves to meet the challenge of the professional requirements in order to meet the ever increasing and diverse needs for good quality service generated from the library users.

  • 교통사고자료를 기반으로 한 사고예측모형의 개발은 사고 발생 후의 처리 측면이 보다 강하며, 교통사고 이력자료(historical data)의 취득이 쉽지않고, 경찰에 보고된 교통사고 건수와 실제 발생한 교통사고 건수와는 불일치하는 경우가 빈번히 발생한다. 또한, 교통사고 이력자료는 운전자의 인적측면이나 현장상황을 보다 현실적으로 고려하기에 어려운 단점이 있다. 근본적인 교차로에서의 안전도 향상을 위해서는 사고발생 이전에 처리할 수 있는 방법의 개발이 필요하다. 교통상충 판단기법은 적은 시간과 한정된 공간에서 조사를 통해 자료를 취득하고 분석할 수 있다는 장점이 있다. 그러나 기존에 이루어지던 수동적인 분석방법은, 분석자의 주관이 반영되기 쉬운 측면이 존재하기 때문에 보다 정밀하고 정확한 교차로의 안전도를 판단하는 지표로 교통상충기법을 이용하기에는 한계가 있음을 확인하였다. 또한, 기존의 교통상충기법은 사고 및 상충이 가지는 심각도에 대한 고려가 부족한 측면이 중요한 단점으로 분석되었다. 이에 본 연구에서는 교통상충을 분석하는데 있어 각 유형별로 상충 심각도를 고려하여 상충을 판단할 수 있는 판단기준을 제시하고, 조사자의 주관이 개입됨으로써 발생할 수 있는 분석의 오류를 제거하기 위하여 영상처리기반의 개별차량 추적기법을 이용하였다. 영상처리기반의 개별차량 추적기법을 이용하여 신호교차로에서 신호위반시 주로 발생하는 대향좌회전 상충과 교차교통 상충에 대한 상충판단알고리즘을 개발하였다. 본 연구에서 개발한 교통상충 판단기준의 적용을 위하여 경기도 성남시의 2개 교차로와 파주시의 1개 교차로의 영상을 취득하여 각각 30분간 분석을 수행하였다. 분석결과, 3개 교차로에서 총 343건의 1단계 상충(신호위반) 상황이 검지되었으며, 이 중 총 25건이 3단계 상충(심각한 상충)으로 발전된 것을 확인하였다. 이를 통하여, 사고발생 이전에 발생하게 되는 상충상황의 분석을 통하여 사고다발지점 등 교차로의 안전도를 평가할 수 있는 대안으로 사용이 가능함을 확인하였다.

  • In Korea, most of the patients with chronic liver diseases have been using some kind of alternative therapies at home. however, the question is why do people turn to alternative therapy and how the patients are able to use the alternative therapies widely, though the effects have not been proven scientifically. Therefore, it is necessary to explore the process of the patients' experiences using the alternative therapies. The 16 participants were from internalmedical departments in hospital and the permission was received to participate in this study from the subjects. The data were collected with interviews and participants observations, analyzed by the grounded theory methodology of Strauss and Corbin(1990). With the analysis of the data, 15 categories were generated such as psychological pressures, barriers of role performances, distrusts of western medicine, blind obediences to the treatments, attitudes towards alternative therapies, supportive systems, obstacles to taking alternative therapies, financial burdens, collecting informations, pursuing alternative modalities, efforting diversities, analyzing by themselves, managing the body, accepting the disease, and ambivalence. The paradigm model was developed to identify the relationships of categories. The central phenomenon of the experiences of seeking alternative therapies was named jagi momdasrim. The central concept of jagi momdasrim is a mind-set to desire to wellness and to take more responsibility for one's own healing by pursuing alternate healing modalities rather than the western medical system. The process of jagi momdasrim evolved several stages such as seeking, finding, struggling, overcoming, fulfilling, and governing the diseases. Four patterns of taking alternative therapies were found as follows: the bulsin-chujong-hyung, the suyoung-hyung, the yangdari-gulchiki-hyung, the chamjae-hyung. In conclusion, the phenomenon of alternative therapies as consumer-driven force to heal the chronic liver diseases of the patients could be explained as an adaptive behavior through the process of jagi momdasrim. However, since most of the participants practicing some kind of alternative therapies had no evidences of its effects and never tried to consult with their medical doctors about alternative therapies, we should approach more actively. Therefore, it is recommended for nurses to listen and watch the patients behaviors of using alternative therapies and find out how to educate the patients about the proper and safe way to take the alternative therapies.

  • This paper focuses on aerodynamic and inertial modeling of the propeller for its applications in flight dynamics analyses of a propeller-driven airplane. Unsteady aerodynamic and inertial loads generated by the propeller are formulated using the blade element method, where the local velocity and acceleration vectors for each blade element are obtained from exact kinematic relations for general maneuvering conditions. Vortex theory is applied to obtain the flow velocities induced by the propeller wake, which are used in the computation of the aerodynamic forces and moments generated by the propeller and other aerodynamic surfaces. The vortex lattice method is adopted to obtain the induced velocity over the wing and empennage components and the related influence coefficients are computed, taking into account the propeller induced velocities by tracing the wake trajectory trailing from each of the propeller blades. Aerodynamic forces and moments of the fuselage and other aerodynamic surfaces are computed by using the wind tunnel database and applying strip theory to incorporate viscous flow effects. The propeller models proposed in this paper are applied to predict isolated propeller performances under steady flight conditions. Trimmed level forward and turn flights are analyzed to investigate the effects of the propeller on the flight characteristics of a propeller-driven light-sports airplane. Flight test results for a series of maneuvering flights using a scaled model are employed to run the flight dynamic analysis program for the proposed propeller models. The simulations are compared with the flight test results to validate the usefulness of the approach. The resultant good correlations between the two data sets shows the propeller models proposed in this paper can predict flight characteristics with good accuracy.
