Severe damage will occur in the near future in an inevitable Nankai Trough earthquake. The working group of the Cabinet Office of the Government of Japan reported damage resulting from Nankai Trough earthquake from August 2012 to May 2013. We constructed a database to include every hospitals in Japan, and, according to the data of the cabinet office, we estimated damage to hospitals and prepared a practical DMAT rescue plan. The Regional Bureau of Health and Welfare provided the hospital list, and we added information to the database about location and altitude provided by the Ministry of Land, Infrastructure, Transport and Tourism and the detailed information about disaster base hospitals.
 Based on information from the cabinet office, we calculated that 257,000 beds (21% of the total number of beds in the stricken area) would be lost. There were 1,249 DMAT teams in April 2014 in Japan, but we estimate, that at least 1,364 DMAT will be necessary to rescue the victims of a Nankai Trough earthquake.

 A mobile-tablet based system is devised dedicatedly for enhancing the quality of dietary habits of family members, which is distinctive in that
 (1) meal contents can be input simply through tablet terminals,
 (2) users are targeted at family members with no health problems,
 (3) the main objective is to seek higher quality of dietary life of each family member, and
 (4) the classification and composition of meal menu are determined to simplify the task of inputting meal contents.
 To see what is the utility of this system as well as to what extent the data entry task is performed in real life, six families are selected for the substantiative experiment of this system. As a result, although the data entry performance differs from family to family, it can be seen for those two families, which achieve almost 100% inputting at each meal, that with the increased use of this system, (i) the operation time is shortened, and (ii) the real calorie intake of each member approaches to the targeted value.
 Eventually, it can be concluded from these results that this system can contribute greatly toward raising the quality of dietary habits of family members.

 The occurrence of deep pressure ulcer limits the utilization of nursing resource and causes unfavorable situation for DPC received hospital. This study focuses on management of pressure ulcer in advanced treating hospital. We compared these two groups: patients with deep pressure ulcer and patients without pressure ulcer of these equal DPC received medical treatment at ‘‘A’’ university hospital in a period from 2007 to 2010. Patients with pressure ulcer stayed in hospital much longer, although their medical revenue significantly fewer. The consumption ratio of medical materials in all medical cost for patients with pressure ulcer were greater. Moreover, the quantity of nursing care burden for patients with pressure ulcer was three times greater. As a result, in the advanced treating hospital, the occurrence of deep pressure ulcer causes wasting medical resources including nursing human resources, and obstructing the effective management in the hospital.

In many cases, guidelines have been published on the Internet in order to be widely disseminated. The purpose of this study was to reveal what kind of challenges are there in providing clinical practice guidelines on the Web by analyzing the results of the usability survey on Minds website that provides clinical practice guidelines information on the Web. The subjects were registered users of Minds website. The survey was carried out in the form of self-administered questionnaire on the Internet. This study revealed that when publishing the clinical practice guidelines on the Web, considering dissemination and utilization aspects, not just publication of the contents, is important. In particular, this study suggested that the website requires a search and display function of the contents which takes into consideration the fact that there are persons other than medical profession in the guidelines users.
