Background: This study examined the effects of cervical traction group and cervical traction & nerve mobilization exercise group after applying conservative physical therapy to Computer Workers with Cervical Radiculopathy. Methods: They were randomly divided into two groups: 18 subjects were cervical traction group, 22 subjects were cervical traction and nerve mobilization exercise group. Each group performed its own exercise 30 minutes per day, three times per week, for 4 weeks. Pain intensity was measured by the visual analogue scale (VAS) and neck disability index (NDI). Cervical extensor muscles strength (CEMS) was measured by the Pressure biofeedback unit. Grasping power (GP) was measured by the Grip Track Commander. Results: After 4 weeks therapy, VAS and NDI were significantly reduced in both groups (p<.05) and CEMS and GP were significantly increased in both groups (p<.05). Significant differences were also evident between the two groups for these three measurements (p<.05). Conclusions: cervical traction and nerve mobilization exercise group is more effective than cervical traction group for reducing VAS and NDI and increasing GP in computer workers with cervical radiculopathy.

Objectives : The purpose of this study was to investigate the relationship between pain and psychological state in female office workers with neck pain. Methods : Experimental group of 31 healthy subjects complained of neck and arm discomfort related to computer use which lasted more than 3 months in the past year and was present in the past 7 days as well as on the day of test. Outcomes were assessed by meridian-electromyography(MEMG), Neck Disability Index(NDI), Visual Analog Scale(VAS), Beck Depression Inventory(BDI), Stress Reaction Inventory(SRI), Holmes & Rahe Social Readjustment Rating Scale(SRRS). Results : The NDI score and BDI score had a correlationship(r=0.48), and the NDI score and SRI score also had a correlationship(r=0.48), significantly. The NDI score and contraction power of upper trapezius by MEMG had a correlationship significantly, but with the other muscles the NDI score didn't have correlationships. The NDI score and the SRI score were significantly higher in depression group(BDI score ${\circ}{\surd}$14). The contraction power of trapezius by MEMG was significantly lower in depression group. Conclusions : The results suggest that mental stress can be a major risk factor of neck pain in female office workers.

Purpose : The purpose of this study was to determine the effects of the McKenzie cervical exercise program on cervical pressure pain and balance in industrial workers. Method : The subjects, who consisted of 26 industrial workers, were randomly divided into two groups. The control group (n=13) went about their daily living routines. The other group (n=13) used the McKenzie cervical exercise program for 6 weeks (2 to 3 times/day). Pressure threshold and balance ability tests were completed before and after the experiment. The balance test was performed both with the eyes open and closed in a standing position. Result : There were significant improvements in the pressure threshold and balance ability test for the McKenzie cervical exercise program group (p<.05), while the control group showed no significant changes (p>.05). Conclusion : The above results revealed that the McKenzie cervical exercise program is effective in improving balance and cervical pressure pain.

Personal exposure levels of $NO_{2}$ for office workers and housewives Living in A-San and neighboring prefectures were measured in two seasons with $NO_{2}$ filter badge. $NO_{2}$ concentrations in indoor and outdoor air in their offices and houses were also measured in the same periods. Personal exposure levels in winter ranged from 13 to 132 ppb and its distribution pattern was remarkably different from the other seasons (15.2-17.9 ppb). This fact suggests that use of heating apparatus affects largely $NO_{2}$ indoor air pollution in winter seasons. Actually, $NO_{2}$ exposure levels of subjects used Kerosene heater (43.6ppb) and gas heater (33.4ppb) were higher than those of subjects unused heating apparatus (18.0ppb). Personal exposure levels of $NO_{2}$ for man and woman Living in the same houses were correlated well each other. The time spent indoors for office workers and housewives were both longer than 22 hour a day. Home staying time was about 60% of total indoor staying time for office workers and 90% or more for housewives. Personal exposure levels were significantly related to indoor exposure levels at home all seasons. Furthermore, personal exposure levels could be estimated from $NO_{2}$ concentrations and staying times in various Living environment.

Purpose: This study was conducted to analyze industrial workers' stresses from physical symptoms, PWI, JCQ and tasks in classification of Sasang constitutions. Method: Data were collected from industrial workers in J Province from May 2003 to June 2003. Questionnaires were distributed and collected on the day of their physical examination. Collected data were analysed through $x^2-test$. Result: Health-related characteristics showed that most of smokers and drinkers were Taeumins and this result was statistically significant. Physical symptoms related to constitutions indicated that GI and neurologic symptoms are significantly more frequent in Soeumin. The percentage of subjects with moderate risk was high in order of Soyangin, Taeumin and Soeumin while the percentage of subjects with high risk was high in order of Soeumin, Taeumin and Soyangin. Conclusion: Through this study, Lee Jae Ma's theory was be confirmed compatible with disease characteristics. However, research with more various subjects and variables needs to be made.

The purpose of this study is to contribute to the improvement of indoor air quality management in dental clinic by investigating the level of indoor air quality recognition among dental clinic workers. The questionnaire survey was conducted for about 4 weeks from May 20 to June 20, 2018 in dental clinics located in Jeollanamdo area and 143 were used as the analysis data. The method of indoor air quality management in dental clinic was preferred to "natural ventilation" method and the number of natural ventilation was 1 to 2 times per day and the results of survey on indoor environment satisfaction showed that satisfaction level was lowest in noise and smell items. The types of subjective symptoms experienced by workers working at dental clinics are "cough", "eye burn", and "headache" and a survey on the degree of the relationship between subjective symptoms and indoor air quality showed that 94.4% (135) of respondents answered "very relevant" and "slightly related". As a result of multiple regression analysis, the variables affecting the indoor air quality satisfaction of the dental clinic staff were analyzed as the items such as lighting, noise, main work, number of patients, comparing indoor and outdoor air quality and among them, "comparing indoor and outdoor air quality" was analyzed as having a great influence. To improve the indoor air quality satisfaction of dental clinic worker adequate ventilation, designate the person responsible for the indoor air quality management and periodic measurement efforts will be necessary.

In traditional fish farming way, the workers have to observe all of the pools every time and every day to feed at the right timing. This method causes tremendous stress on workers and wastes time. To solve this problem, we implemented an automatic detection system for feeding time using deep neural network. The detection system consists of two steps: classification of the presence or absence of feed and checking DO (Dissolved Oxygen) of the pool. For the classification, the pretrained ResNet18 model and transfer learning with custom dataset are used. DO is obtained from the DO sensor in the pool through HTTP in real time. For better accuracy, the next step, checking DO proceeds when the result of the classification is absence of feed several times in a row. DO is checked if it is higher than a DO reference value that is set by the workers. These actions are performed automatically in the UI programs developed with LabVIEW.

민주노조운동과 노동계급 형성의 후퇴기에 비정규직 노동자들이 투쟁과 함께 새로운 계급형성의 잠재적 주체로 등장했다. 하지만 주체 형성의 효과는 아직 나타나지 않고 있다. 그렇다면, 왜 투쟁은 성과를 내지 못했는가? 어떤 변인들과 인과적 메커니즘을 통해 투쟁의 성과가 결정되는가? 이러한 물음들에 대한 답변을 구하는 것이 본 연구의 목적이다. 정규직 투쟁에 비해 비정규직 투쟁은 자본의 공세에 대응하는 수세적 방어적 성격이 짙고, 생산현장 접근성 제약으로 파업 투쟁 이외의 방식에 의존하며, 사측의 비타협성으로 인해 장기화되고, 교착상태를 타개하기 위해 극단적 투쟁 방식에 호소하며, 정규직 연대 확보가 어려워 외부연대에 크게 의존하는 차별성을 지니고 있다. 비정규직 투쟁은 승리보다는 패배, 조직력 강화보다는 약화로 귀결되는 경향이 강하다. 패배 경향성을 상쇄하고 승리하기 위해서는 비정규직 주체들의 조직 동원 역량과 정규직 노조의 연대가 절대적으로 필요한 조건이며, 강력한 사회적 연대나 위치적 권력은 정규직 연대의 대체재 역할을 할 수 있다. 또한, 투쟁이 조직력 강화로 이어지기 위해서는 투쟁의 승리가 필요하지만 투쟁의 승리로 쟁취한 정규직화가 승리의 덫이 될 수도 있다. 정규직 노조의 연대와 투쟁 주체의 내적 통합은 비정규직 투쟁이 승리하고 조직력을 강화하는데 크게 기여하는 것으로 나타났다. 투쟁을 전개하는 부분은 비정규직 노동자들 가운데 조직력이 가장 강한 부분인데 이들이 투쟁 과정에서 조직력 위축 혹은 조직 와해를 겪으면서 비정규직 주체 형성을 어렵게 한 것이다. 하지만, 비정규직 투쟁이 없었더라면 자본의 공세가 그대로 관철되었을 것이라는 점에서 비정규직 투쟁은 적어도 자본의 공세를 약화 혹은 지연시킨 효과는 거두었다고 할 수 있다. 또한 유형 설정자 역할의 부담 속에서 강경투쟁 전략과 양보타협 전략 사이의 투쟁 전략 딜레마는 투쟁 주체의 분열을 심화하여 투쟁의 승패와 조직력 변화에 부정적 영향을 미치게 된다. 비정규직 투쟁의 실천적 함의는 비정규직 투쟁의 궁극적 목표를 노동계급 형성을 위한 주체형성으로 재정의한다면 비정규직 투쟁의 전략적 목표는 당면 요구조건의 완전한 쟁취보다 조직의 보전 강화에 두는 것이 합리적 선택이라는 점이다.

The purpose of this study was to investigate the effects of sleep/wake behavior for shiftwork in air traffic controllers (ATCs) using wrist actigraph for ten workers on a continuous full-day three-team three-shift system of forward rotation including on-duty and off-duty periods. The wrist actigraph data were recorded for three days (one shift cycle) for each subject. The mean activity counts during an on-duty period progressively increased from the night, the swing, to the morning shifts. The doze length during on-duty periods showed decreases in the morning and swing shifts as compared to the night shift. Total sleep time (TST) and sleep efficiency (SE) during off-duty periods increased in the morning-1 and swing-night shift compared to the morning-2 shift. Finally, I discussed the role of doze-taking during the burden on night shift ATCs.
