In recent years, the stress levels in the workplace have gotten worse and worse. The situation has aroused a sreat deal of public interest in mental health. Workers have become more conscious of their own stress levels. The incidences of stress-induced mental illness and overwork-related suicide have increased to the point of amajor social issue. With this knowledge, corporations are thinking in termes of improving their organizational work environment. Becoming aware that stress on the job ia a serious mental health hazard, some organizations are introducing an inhouse system to help employees, with mental problems due to workplace stress. This article reports on the 3-year-old system we have integrated into our hospital to support those employees suffering from workplace stress. First we established a consultation room. Since it opened, everything has progressed smoothly. The number of cases and number of consultations have been increasing each year. Along with the advancement of mental health care and support, we have made efforts to establish a coordination framework, both internally and externally, for bringing to light workplace cardio-health problems, stress management, and rehabilitation. So, you can see we have constructed a strong foundation of a mental health care system for the personnel of the hospital.

In recent years, the unique nature of medical profession, overwork and increased medical lawsuits, have significantly complicated medical profession. In this stressful work environment, the shortage of nurses in most medical institutions has brought problems on staff turnover prevention to the forefront and increased the need for a variety of support measures to be taken to help counteract this high turnover. In order to create a better working environment in our hospital, we have begun grappling with the delivery of mental health care for our staff.　　In this report, we have checked new and inexperienced nurses in a questionnaire survey and recorded the findings over time. Immediately after their assignment, there was a very high incidence of physical and mental fatigue. It was revealed, however, that there were signs for improvements in fatigue as they had entered their second year of employment. That said, however, we found that there still remained a high degree of depression and a low degree of self-efficacy.　　Recognizing that being a nurse is a task with a high work load in a stressful work environment, we would like to reiterate the importance of creating a support system of ongoing education and stress management.

  The purpose of this research was to clarify factors that make early hospital discharge difficult. We found that this hospital was different from other general hospitals. We repeatedly revised early discharge guidelines and were able to find factors reliable about 24% higher.
  Our findings would contribute to the shortening of hospital stay, the promotion of the efficiency of our work, the strengthening of regional alliances. What we should consider most important is the realization of the discharge that is not forced.

Purpose: This study aimed to assess the performance of 2-dimensional (2D) imaging with microscopy coils in delineating teeth and periodontal tissues compared with conventional 3-dimensional (3D) imaging on a 3 T magnetic resonance imaging (MRI) unit. Materials and Methods: Twelve healthy participants (4 men and 8 women; mean age: 25.6 years; range: 20-52years) with no dental symptoms were included. The left mandibular first molars and surrounding periodontal tissueswere examined using the following 2 sequences: 2D proton density-weighted (PDw) images and 3D enhanced T1 high-resolution isotropic volume excitation (eTHRIVE) images. Two-dimensional MRI images were taken using a 3 T MRI unit and a 47 mm microscopy coil, while 3D MRI imaging used a 3 T MRI unit and head-neck coil.Oral radiologists assessed dental and periodontal structures using a 4-point Likert scale. Inter- and intra-observer agreement was determined using the weighted kappa coefficient. The Wilcoxon signed-rank test was used to compare 2D-PDw and 3D-eTHRIVE images. Results: Qualitative analysis showed significantly better visualization scores for 2D-PDw imaging than for 3D-eTHRIVE imaging (Wilcoxon signed-rank test). 2D-PDw images provided improved visibility of the tooth, root dental pulp, periodontal ligament, lamina dura, coronal dental pulp, gingiva, and nutrient tract. Inter-observer reliability ranged from moderate agreement to almost perfect agreement, and intra-observer agreement was in a similar range. Conclusion Two-dimensional-PDw images acquired using a 3 T MRI unit and microscopy coil effectively visualized nearly all aspects of teeth and periodontal tissues.
