  • Occupational Stress among Japanese Emergency Medical Technicians: Hyogo Prefecture

  • Introduction:

    As prehospital care became emphasized in emergency medical services in Japan, qualification as a “paramedic” was established in 1991 as a requirement for national qualification as a emergency medical technician (EMT).With recent increases in emergency transportation, the responsibilities of paramedics have become more complex and demand a higher level of competency; however, no method of evaluating occupational stress among Japanese EMTs currently exists.

    Methods:

    A questionnaire survey of the working conditions and health of 2,017 EMTs in Hyogo Prefecture was conducted. To analyze stress levels among these EMTs, the survey was divided into two categories: (1) physical stress; and (2) mental stress.

    Results:

    The number of responses was 1,551 (76.9%) and the average age of the respondents was 35.4 years. The lower back, neck, and shoulders were most frequently subjected to physical stress, which was related to the daily operations as an EMT. Mental stress was reported more frequently by those who were older or qualified paramedics.

    Discussion:

    The high frequency of lower back pain suggests the need for improvement in the work environment and periodic education.

    Conclusions:

    Although job satisfaction among paramedics was high, they were exposed to greater mental stress. Therefore, systematic management of stress must be developed and established.

  • A smooth projective algebraic 3-fold V over the field C is called a Fano 3-fold if the anticanonical divisor — Kv is ample. The integer g = g(V) = ½(- Kv)3 is called the genus of the Fano 3-fold V. The maximal integer r ≧ 1 such that ϑ(— Kv)≃ ℋ r for some (ample) invertible sheaf ℋ ε Pic V is called the index of the Fano 3-fold V. Let V be a Fano 3-fold of the index r = 2 and the genus g = 21 which has the second Betti number b2(V) = 1. Then V can be embedded in P6 with degree 5, by the linear system |ℋ|, where ϑ(— Kv)≃ ℋ2 (see Iskovskih [5]). We denote this Fano 3-fold V by V5.
