본 연구는 융 복합 시대에서 직무 임베디드니스의 중요성을 인식하고, 직무 임베디드니스가 직무몰입에 미치는 영향과, 직무의미성이 이들 간의 관계에 있어서 조절효과를 하는지 실증검증을 통해 살펴보고자 하였다. 검증결과, 첫째, 직무 임베디드니스의 적합성과 희생 및 연계의 요인들은 직무몰입에 긍정적인 영향을 미치는 것으로 나타났다. 둘째, 직무의미성에 따라 직무 임베디드니스가 직무몰입에 미치는 영향은 대부분 달라지는 것으로 나타났다. 하지만 직무 의미성의 기술다양성과 과업정체성은 직무 임베디드니스의 적합성이 직무몰입에 미치는 영향에 대한 조절효과가 없는 것으로 나타났다. 이는 직무가 작업자에게 기능과 능력을 충분히 발휘할 수 있는 기회를 제공한다 할지라도, 작업자가 직무에 대한 스트레스, 동기수준 등과 같은 태도에 영향을 더 많이 받을 수 있으며 결과적으로 직무에 대한 몰입이 어려울 수 있음을 의미한다. 이러한 연구 결과는 학술적 실무적으로 시사하는 바가 클 것으로 사료된다.

Purpose : The purpose of this study is to identify the degree of occupational therapist's professional ethics and to examine the correlation between professional ethics, job stress, and burnout. It also investigates the effects of the occupational therapist's professional ethics on job stress, and burn out, so that we can find a way to reduce them in occupational therapists. Methods : We conducted surveys from June 1 to July 5, 2022. The general characteristics were examined using a frequency analysis. Professional ethics, job stress, and burn out were examined using descriptive statistics. The correlation among them was analyzed with the Pearson correlation coefficient. To find out what factors affect job stress and burn out, we also conducted a multiple regression analysis. Results : First, professional ethics was averaged at 3.57±.34. Second, a significant negative correlation in professional ethics was found between job stress and burn out (p<.01). As a result of the correlation between occupational ethics sub-factors and job stress and burnout, factors excluding nonleisure and self-reliance showed a statistically significant correlation (p<.01, p<.05). Third, professional ethics sub-factor was affected job stress and burn out (p<.01, p<.05). The sub-factors affecting job stress were hard work (𝛽=.-461, p<.01), delay of gratification (𝛽=.-267, p<.01), and relation with coworker (𝛽=.-245, p<.01) and morality (𝛽=.-165, p<.05); and those influencing burnout were delay of gratification (𝛽=-.240, p<.01), relation with coworker (𝛽=-.223, p<.01), centrality of work (𝛽=-.189, p<.01) and hard work (𝛽=-.184, p<.05).

FFT 나 AR 방법에 기초해서 파워스펙트럼을 구하는 방법은 생체신호와 같이 시간에 따라 그 특성이 빠르게 변화하는 신호에는 적합하지 않다. 반면, 시-주파수 방법은 시간에 따라 특성이 변하는 신호를 분석하기에 유용한 장점을 지니고 있다. 본 논문에서는 시-주파수 분석방법을 이용하여 시-주파수 영역에서 심박변동신호를 분석하는 방법을 연구하였다. 여러 종류의 시-주파수 커널 함수들 중에서 심박변동 신호에 적합한 방법을 찾기 위해서 모의 HRV 신호를 이용하였다. HRV 모의신호를 이용하여 커널 함수들의 시간-주파수 분해 능력과 교차성분제거 능력에 대한 평가를 하였고 시-주파수 영역에서 심박변동신호의 주파수 성분들을 추출해 내는 방법들을 제시하였다. 17명의 피험자들을 대상으로 동전쌓기 실험을 3분씩 시행하여 심전도 실험을 측정한 다음 이를 심박변동 신호로 재구성하여 분석하였다. 실험결과 피험자들에게 가해진 정신적 스트레스는 교감신경을 활성화 시켜 LF/HF 증가의 원인이 되는 것으로 나타났다. 실험수행능력에 따라 두 그룹으로 나누어 관찰하였는데 스트레스를 많이 받는 그룹이 그렇지 않은 경우에 비해 작업능력이 떨어짐을 알 수 있었다.

The aim of this survey is to investigate the occupational musculoskeletal disease and stress levels of restaurant cooks and to provide a basic data of programs in order to prevent occupational diseases. A questionnaire survey was conducted on 220 subjects in Gangwon province. The results show that there was no significant difference in the degree of occupational musculoskeletal disease between male cooks and female cooks. However, western cuisine cooks were more likely to have a higher degree of occupational musculoskeletal disease than other cuisine cooks and showed a higher degree of occupational stress from work overload as well as irregular meal stresses. Cooks aged from 30 to 40 years showed a higher level of occupational musculoskeletal disease in the neck, shoulder, and hand/wrist compared to those in other age groups. The job tenure was related to the degree of musculoskeletal disease in knee. Additionally, the hours of working per day were statistically significantly related to musculoskeletal disease in the knee and to the occupational stress levels in irregular meals stress. The findings of this study suggest that it is essential to design customized education for cooks to lessen their occupational musculoskeletal diseases and stresses in order to ensure the health and safety of the culinary workers.
