Methods: We compared 3 ap-proaches: 1) a standard needs assessment questionnaire, the Camberwell assessment of need in the elderly, 2) an open-ended listing of needs, and 3) participation in a narrative medicine program in which health care professionals were involved. Results: On the questionnaire, patients reported physical needs as the most important while their caregivers were more concerned about psychological needs. The open-ended listings revealed additional needs, particularly access to re-liable information about PD and to opportunities to participate in clinical research. The narrative medicine process yielded a number of new insights and proposed solutions, particularly related to the heterogeneity of needs across individuals, the importance of providing hope, and the fact that caregivers expressed that their needs had been largely neglected. Participation in the narrative medicine sessions led to an increase in measured empathy by health care professionals, an im-provement in measured depression among PD patients, but a worsening of measured depression among the caregivers. Conclusions: We have identified important needs and potential solutions to be considered in providing long-term support to patients with PD and their caregivers.展开更多

In the Age of Discovery, the image of China in the eyes of Western envoys, merchants and missionaries begun to fade away from traditional mythological and psychedelic colors, and the image of cultural elements such as material, spirit and history become clear. These Western travelers tried to shape the image of China as a state of civilization and wisdom, a state of moral order, and a state of wealth and power. On the basis of the continued description of the kingship and wealth of the Middle Ages, they constructed an overall image of China as a powerful state of civilization and wealth, thus forming a new frame of reference for cognition of China.展开更多

A juxtaposition of the writers' reaction to the dynamics of gazing and the ethics of touch yields surprising results. Many women travellers have no problem to acknowledge the reciprocity of the gaze, accepting, as a matter of course, that the objects of their ethnological interest will gaze at them in return. In comparison, male travellers often exhibit unease at becoming an object of appraisal and observation. Even more interestingly, male travellers often shy away from haptic contact with members of the indigenous population, whereas many (though not all) women are more tolerant of touch and proximity. Regarded as "unwomanly" by their contemporaries, they carved out for themselves roles which allowed for a more intimate interaction with foreign ethnicities; also, they wrote in different genres--private memoirs instead of official reports. But even in their (semi) fictional writings male authors seem to imagine inter-cultural encounters in different terms from women and tend not let their protagonists enter into close bodily contact with the indigenous population.展开更多

The purpose of the present work is to study various types of Burger’s equations describing waves and those are based on nonlinear equations. We focus on to describe the analytic solution in the special pattern of travelling wave solutions using tan-cot function method. We discuss about inviscid and viscous version of Burger’s equation for fluid flow and investigate the effects of internal friction of a fluid via Reynolds number. By changing the velocity amplitude, the nature of flows with shock wave and disturbance are observed. For numerical solutions, the Crank-Nicolson scheme is introduced to establish the wave solutions.展开更多

There are some evidence by his wife and friends that Sōseki's condition of disease dramatically improved during its serialization on a magazine, and the writer himself admited humorously in the preface of other work that it was his depression and mania that enabled him to produce I Am a Cat and other early works. This paper aims at describing the process how his act of narrating had therapeutic effects on his state of mind focusing on the construction of complicitous relationship between an implied author and readers in the work by the unique functions of the first-‘person' narrator: A Cat. Among others, I will consider the influence of Laurence Sterne's Tristram Shandy(1759-1767), which Sōseki introduced to Japan for the first time, by discussing the frequent use of metalepsis that the two works have in common.展开更多

When these parameters are taken to be special values, the solitary wave solutions are derived from the exact traveling wave solutions.

Calculated results show that this technique overcomes some defects of traditional forward calculation method, and it is also very effective to determine Poisson's ratio distribution of deep seismic sounding profile, especially useful for study on volcanic magma and crustal fault zone. Study result indicates that there is an abnormally high Poisson's ratio body that is about 30 km wide and 12 km high in the low velocity region under Tianchi crater. Its value of Poisson's ratio is 8% higher than that of surrounding medium and it should be the magma chamber formed from melted rock with high temperature. There is a high Poisson's ratio zone ranging from magma chamber to the top of crust, which may be the uprise passage of hot substance. The lower part with high Poisson's ratio, which stretches downward to Moho, is possibly the extrusion way of hot substance from the uppermost mantle. The conclusions above are consistent with the study results of both tomographic determination of 3D crustal structure and magnetotelluric survey in this region.展开更多
