이 연구의 목적은 바리스타에게서 나타나는 작업 관련한 상지 근골격계 통증 상태를 조사하고 통증과 관련된 요소를 확인하는 것이었다. 연구대상은 전주시의 카페 근무자로 하여 통증 현황을 조사하였고 그 중 통증 고위험군을 대상으로 통증 영향 변수를 조사하였다. 업무 관련 통증을 조사한 결과, 65.3%에서 적어도 1주일, 1개월 또는 1년 내에 통증이 있었다고 응답하였다. 대부분의 근로자는 오른손잡이였고 하루의 25~50%의 시간 동안 통증을 느꼈다고 하였다. 특히 일하는 중 포터 필터를 사용하는 것이 가장 고통스럽다고 보고하였다. 향후에 카페 작업자의 질병을 예방하기 위한 프로그램을 도입하고 개발하는 것이 필요하고, 카페 작업의 특성에 따라 작업 환경과 자세를 개선하기 위한 향후 연구가 필요하다.

The purpose of this study was to investigate the current status of work-related upper extremity musculoskeletal pain in baristas and to identify the elements that are related to pain. The questionnaires were distributed to 100 workers in 63 cafes on Jeonju city in Korea. As a result of investigating work related pain, 65.3% (n=64) answered "yes" to the question that had pain at least once a week, month, or year, or 34.7% (n=34) answered "no". Most of the workers were right-handed, and when they felt pain, they felt 25 to 50% of time per day. Especially, baristas reported that the use of porter filters during work and the tamping operation were the most painful. In conclusion, our study indicated that necessary to introduce and develop a program to prevent cafe worker disease, as well as need to future research to improve work environment and posture according to the characteristics of the cafe works.

문제 정의
'Angulus' is an application that measures the angle of the body based on images or videos. In this study, we confirmed the exact wrist angle through the application. It was developed in cooperation with a physical therapist to replace the goniometer and is an application that can measure and record joint range of motion.
The purpose of this study was to investigate the current status of work-related musculoskeletal pain in baristas and to identify the elements that are related to pain. As a result of analyzing questionnaire data, they were mainly make up 20s to 30s young people, and had mostly working on weekends or weekdays.
However, most of the researches on the musculoskeletal diseases have been studied about nail polishers, hoteliers, farmers, or assembler[5-8]. The purpose of this study was to investigate the status of musculoskeletal pain in barista and to investigate the variables related to pain affecting them.
This study had conducted a self-report questionnaire survey on the status of upper extremity pain in 100 baristas on Jeonju city in Korea. All the participants were informed of the study and agreed upon.
제안 방법
Only eight baristas participated in high risk group survey. And, a researcher evaluated the motion of using the porter filter and the motion of tamping for espresso extraction. The wrist angle axis was measured in the radial styloid process on the anatomical snuffbox.
Descriptive statistics are used to describe the basic features of the data in this study. Statistical analysis was performed with SPSS 24.
First, we invested their working type and working period. Second, we used the modified PQRST-test which consist of eight items to confirm their pain aggravation and relief, pain pattern, pain severity, duration of pain. Last, the 42 high-risk participants with a Visual Analogue Scale(VAS) score of 5 or higher point in general condition carried out a Job Strain Index(JSI) assessment and the 'Angulus' evaluation to confirm more specific pain-influencing variables.
JSI is evaluation tool which is developed by Moore and Garg(1995) that this study used to evaluate the risk factors of work-related musculoskeletal disorders at upper extremities (hands, wrists, and elbows) for baristas[10]. The JSI items are consisted of intensity of exertion, duration of exertion, efforts per minute, hand / wrist posture, speed of work, and duration of task per day. The JSI score is calculated by multiplying all six coefficients.
The self-report questionnaire consisted of eight items. The modified PQRST-test consists of pain aggravation and relief, pain pattern, pain severity, duration of pain. Fig.
The modified PQRST-test was based on the Nordic-style questionnaire and the questionnaires were added the VAS concept to confirm the intensity of pain. The self-report questionnaire consisted of eight items.
대상 데이터
All the participants were informed of the study and agreed upon. As a result, 98 participants were selected as participants of this investigation (excepted two non-responders). Table 1.
Participants consisted of 70 female and 28 male baristas. They were mainly make up 20s to 30s young people, and had mostly working on weekends or weekdays.
The modified PQRST-test was based on the Nordic-style questionnaire and the questionnaires were added the VAS concept to confirm the intensity of pain. The self-report questionnaire consisted of eight items. The modified PQRST-test consists of pain aggravation and relief, pain pattern, pain severity, duration of pain.
This study examined the present status of Espresso Maker 's Wrist among 100 people in 63 coffee shops.
이론/모형
JSI is evaluation tool which is developed by Moore and Garg(1995) that this study used to evaluate the risk factors of work-related musculoskeletal disorders at upper extremities (hands, wrists, and elbows) for baristas[10]. The JSI items are consisted of intensity of exertion, duration of exertion, efforts per minute, hand / wrist posture, speed of work, and duration of task per day.
성능/효과
The scores of the JSI items of the eight high-risk participants were as follows. Table 3. The JSI score of the high risk group of pain was more than 7 points and classified results that job is probably hazardous. All high risk participants had exposing to one or more of the risks during barista work.
The duration of the 1-day task was confirmed to over 8 hours. Table 4. There were individual differences in duration of power, frequency of power per minute, and work speed, but did not significantly affect SI results. The upper extremity load is mainly due to weight loading and wrist bending when tamping and steam feature hits the surface to break in milk foam, and had confirmed ulnar deviation when using a coffee machine.
The greater the intensity and duration of exertion, the more exertion of force per minute, the faster the hand/wrist posture, the faster the work speed, the longer the duration of work per day, the greater the risk of WRMSDs. It was found that the posture, activity load and frequency during the work such as repetitive porter filter use of the worker, dishwashing, inventory clearance, and tamping were in agreement with the risk factors of WRMSDs.
First, there were a lot of dropouts due to the problem of discipline in business. Second, the method of working was different for each subject even in the same work, and it was difficult to deal with the external variables of the workplace environment. Third, self-report questionnaires and JSI research may have a subjective view.
후속연구
Further study will be necessary to provide work environment and conditions that can work in a more comfortable environment by reducing the incidence of workers' diseases by studying not only musculoskeletal problems experienced by baristas but also psychological problems.
However, there are not many studies on the current status and problems of baristas, so there is a limit to finding fundamental solutions to the problems. This study will be the basic data to support the related research in the future. Our study had some limitations.
