According to the 2020 industrial accident reports of the Ministry of Employment and Labor, the number of fatal accidents in the construction industry over the past 5 years has been higher than in other industries. Of these more than 50% of fatal accidents are initially caused by fall accidents. The central government is intensively managing falling/jamming protection device and the use of personal protective equipment to eradicate the inappropriate factors disrupting safety at construction sites. In addition, although efforts have been made to prevent safety accidents with the proposal of the Special Act on Construction Safety, fatalities on construction sites are constantly occurring. Therefore, this study developed a model that automatically detects the wearing state of the worker's safety helmet and belt using computer vision technology. In considerations of conditions occurring at construction sites, we suggest an optimization method, which has been verified in terms of the accuracy and operation speed of the proposed model. As a result, it is possible to improve the efficiency of inspection and patrol by construction site managers, which is expected to contribute to reinforcing competency of safety management.

Flight instructors at aviation training centers are exposed to various stresses, such as stress caused by special work environments, stress caused by working conditions, and stress related to uncertain future airline employment. These stresses are expected to not only affect flight safety, but also adversely affect the job satisfaction of flight instructors, and consequently negatively affect the performance of high-quality flight education. Therefore, this study was conducted to understand the effects of these stresses on the job satisfaction of flight instructors by examining the stress experienced by flight instructors in flight, psychological, and physical aspects based on the results of previous studies on stress. To the end, this study conducted a survey of flight instructors belonging to aviation training centers, and as a result of analyzing the collected data, it was confirmed that the physical stress of flight instructors had a significant negative effect on their job satisfaction.

Objectives: Borderline intelligence has been excluded from formal diagnostic systems and not included in disability diagnoses, leaving gaps in treatment, education, and social welfare despite various functional impairments. Therefore, we aimed to shed light on ways to enhance the intelligence and functioning of individuals with borderline intelligence by reviewing research on its progression, education, and treatment. Methods: Ten studies that met the inclusion and exclusion criteria were included in the final literature review and analyzed according to detailed topics (participant characteristics, design, and results). Results: Borderline intelligence is associated with various comorbid conditions, such as anxiety, depression, attention deficit/hyperactivity disorder, and addictive disorders, which negatively impact its course and prognosis. Individuals with borderline intelligence often face challenges in academics, employment, interpersonal relationships, and health owing to lifelong cognitive impairments. The treatment of borderline intelligence necessitates addressing environmental factors, such as neglect and abuse, as well as treating comorbid mental disorders, which are crucial for prognosis. Tailoring treatment programs for cognitive profile characteristics have been proposed, and studies have reported the effectiveness of pharmacotherapy, working memory training, and intensive rehabilitation training. Therefore, early intervention during childhood brain development is necessary. Risk factors, such as lack of parental education, and their impact on treatment outcomes have also been reported. Conclusion: Extensive research is needed on education, treatment, and prognosis related to borderline intelligence. Active intervention for children with borderline intelligence is essential to improve their functioning and quality of life.

The goal of this study is to analyze the complicated and diverse nature of the relationship between work and family life for the study paper instructors of whom are married women. The survey data for these analyses were from an in depth interview which was conducted with the 21 contingent female workers as study samples. They are the married women, who started to work or returned to work after an absence to raise a family. The results showed that in reality the contingent female worker faced worse working conditions than the full time female labour force, even if women were determined to be a study paper instructor to meet work and family demand. It was the contingent women worker with a short time work experience who were in the worst position tlo adjust their working arrangements to suit their family needs and were confronted with the greater inter-role friction as a vulnerable group. The study revealed that instrumental and emotional support of husband has a positive effect on maintaining job role and lessening role conflicts and stress of the women. The work/family relationship indicated its double side, conflict and support. The women simply could not afford to depend on the psychological support form family in the midst of the inferior employment conditions and the absence of social support. This strategy, however, was based on the family ideology and the patriarchal gender division of labor. It caused the overload, stress and poor health of women involving some risk to give up the work.

The muscular-skeletal disorders(MSDs) that have become a major issue recently in Korean industrial safety area are mainly caused by manual material handling task. The objective of this study is to provide scientific data for the establishment of work safety standard for Korean workers through the experiments of lifting task under various conditions, in order to prevent the muscular-skeletal disorders in the industrial work site. Eight male college students were recruited as participants. Three different lifting frequencies(1, 3, 5 lifts/min) and three twisting angles(including the sagittal plane and two asymmetric angles; i.e., 0°, 45°, 90°) for symmetric and asymmetric tasks, respectively, with three lifting range from floor to knuckle height, knuckle to shoulder, floor to shoulder height for one hour's work shift using free style lifting technique were studied. The maximum acceptable weight of load(MAWL) was determined under the different task conditions, and the oxygen consumption, heart rate, and RPE were measured or recorded while subjects were lifting their MAWLs. The results showed that: (1) The MAWLs were significantly decreased as the task frequency and task angle increased.; (2) The heart rate, oxygen consumption, RPE significantly increased with an increase in lifting frequency although maximum acceptable weight of lift decreased.; (3) The highest heart rate and oxygen consumption was recorded at the lifting range of floor to shoulder, followed by floor to knuckle and knuckle to shoulder.; (4) The RPE value showed that subjects perceived more exertion at the high frequency rate of lifting task and lifting range of floor to shoulder height. (5) The modeling for MAWL using isometric strength, task angle and lifting frequency were developed. It is expected that use of the results provided in this study may prove helpful in reducing MMH hazards, especially from lifting tasks for Korean, and can be used as a basis for pre-employment screening.

The purpose of this study was to investigate the social exclusion of 'Da-Ka-Gu' rental housing and permanent rental apartments and to provide basic source of their socio-demographic characteristics and actual conditions of social exclusion. Self-administered questionnaires and interviews were carried out with 212 dwellers in 'Da-Ka-Gu' rental housing and permanent rental apartments in the city of Gwangju from July to October of 2010. The main findings are: 1. The social exclusion of physical deficiency dimension composed of income and employment has been found to be the most serious level, compared to all the other dimensions. 2. The social exclusion from health has been found to be the highest level in the dimension of the approach to social rights. The next highest level has been found to be the social exclusions from residential areas and education and service areas. 3. The level of social exclusions from the areas of family relations and social relations, which are in the dimension of social participation, has been found to be next highest to the level of physical deficiency dimension. 4. The level of exclusion from cultural and normative integration has not been found to be of significant difference between the two types of residence in this study. This study of the actual conditions of social exclusion among residents living in 'Da-Ka-Gu' rental housing and permanent rental apartments suggests the necessity and some practical implications for policy measures of social integration for the residents of lowincome housing.

The purpose of this study was to investigate the effect of work factor/home factor on health status in women office workers. This study investigated the relationship of various influencing factors between health status using claims data of the The Fifth Korean Working Conditions Survey sample from 2017. To this end, we employed logistic regression analysis using sample data from 3,115 female office workers. Logistic regression results indicate that influential factors were ages, employment status, satisfaction with the work environment, sex ratios at workplace, economic burden, childcare burden, housework burden. We discussed several policy and academic implications. As women become more active in society, the number of female workers is increasing. If employers improve the health status of female workers, they will benefit from improved productivity in their business. Therefore, improving the work conditions of the those female workers is very important. Also, practical policy considerations should be needed for female workers to strengthen their social capital in order to enhance their status of health.

This study examines degree of fairness migrant workers in Korea feel with their wages in comparison to those of their homeland and Korean workers who do the same job in Korea as theirs, and what factors affect the feelings. For the study, 742 migrant workers from China, Vietnam, Philippines, and Indonesia employed by manufacturing firms in Seoul and Gyenggi areas were surveyed. The results show that most migrant workers in Korea feel unfair about their wages, and the feeling of unfairness appears more strongly when comparing with the Korean workers than with their homeland workers. The effectiveness of variables affecting fairness also varies according to the object of comparison: in comparison to homeland workers, age, sex, monthly income before migration, money spent for employment, and satisfaction with working conditions are significant: in comparison to Korean workers, ethnicity, sex, legal status, satisfaction with working conditions are significant.
