The purpose of this study was to investigate the job stress factors of aircraft composite material part manufacturing workers using survey based on 'Job stress factors evaluation tool for Koreans' that was developed by KOSHA in 2003. Two hundred and fifty workers participated in this study, and among them 204 responses were analyzed for this study due to the unreliability and insincerity of responses. The eight job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation, relationship conflict, and job requirement were analyzed. The results showed that the stress level of the six job stress factors which are physical environment, job autonomy, job insecurity, organizational system, workplace culture, unfair compensation was relatively higher than that of other industry workers. Generally, all eight job stress factors showed higher stress with temporary workers than with permanent workers, and especially job autonomy, job insecurity, organizational system, and unfair compensation factors showed statistically significant differences (p<0.05). Since the temporary workers are insecure with their job, weak position in organization, having little self-control for the job and lower pay level than that of permanent workers though the job is as same as permanent workers', the stress level of above job stress factors would be much higher than that of the other factors. The group of unsatisfactory with workplace showed higher job stress than group of satisfactory with workplace in all job stress factors, as expected, at the statistically significance level (p<0.05). From the results of this study, the work loss due to the job stress could be prevented, and accurate stress factors could be removed at the workplace. Also the job stress management program can be implemented to improve the work efficiency and the workers' quality of life.

Multi-object tracking (MOT) is a vital component in understanding the surrounding environments. Previous research has demonstrated that MOT can successfully detect and track surrounding objects. Nonetheless, inaccurate classification of the tracking objects remains a challenge that needs to be solved. When an object approaching from a distance is recognized, not only detection and tracking but also classification to determine the level of risk must be performed. However, considering the erroneous classification results obtained from the detection as the track class can lead to performance degradation problems. In this paper, we discuss the limitations of classification in tracking under the classification uncertainty of the detector. To address this problem, a class update module is proposed, which leverages the class uncertainty estimation of the detector to mitigate the classification error of the tracker. We evaluated our approach on the VisDrone-MOT2021 dataset,which includes multi-class and uncertain far-distance object tracking. We show that our method has low certainty at a distant object, and quickly classifies the class as the object approaches and the level of certainty increases.In this manner, our method outperforms previous approaches across different detectors. In particular, the You Only Look Once (YOLO)v8 detector shows a notable enhancement of 4.33 multi-object tracking accuracy (MOTA) in comparison to the previous state-of-the-art method. This intuitive insight improves MOT to track approaching objects from a distance and quickly classify them.

Traditionally most of studies on voluntary turnover have focused on identifying the determinants of it under the implicit assumption that negative attitudue raises turnover rate and, in turn, it undermines organizational effectiveness. But, recently many scholars have argued that more focus be placed on the functionalty than the frequency of turnover. Based on the recent trend of voluntary turnover, this paper is to analyse the differences of the Intention to Leave(IL) level according to job characteristics(job variety, job importance, job autonomy, job identity, feedback)$\times$functionality(employee ability, attitude). Resulting from 2-way ANOVA, the Negative-attitude Group(NG) is found to expose significantly high IL level than the Affirmative-attitude Group(AG) in low job variety, low job autonomy, low job importance.

The influence of depression, self-esteem, and well-being components of maternal psychological environment on child behavior problems was examined in Korean and American populations. Findings were that the level of mother's self-esteem was lower in Korean than in American mothers; the level of mother's "autonomy" and "environmental mastery" was lower in Korean than in American mothers; and "somatic complaints" were more frequent in the Korean group. The relationship between maternal psychological environment and child behavior problems was greater in the American group. In the Korean group, autonomy and enviornmental mastery were negative components causing both internalized and externalized behavor problems in children. Mothers' depression was the most powerful variable, affecting internalized and externalized behavior problems in both Korean and American groups.

This study aims to investigate the effects of job characteristics and work on both organizational commitment and job satisfaction of the school foodservice dietitian for the purpose of providing information for quality improvement in productivity of school foodservice. The subjects were 401 school foodservice dietitians in Taegu and the Kyungpook area. The survey questionnaires consisted of five parts including demographic characteristics, job characteristics(JCI), work values, organizational commitment(OCQ) and job satisfaction(JDI). More than half of the subjects(65.3%) were between the age of 26 to 30 years. Seventy-one percent of the participants had bachelor’s degrees and monthly wages of 83.2% ranged from 700,000 to 1,200,000 won. The education of thedietitians was found to have a significant relatinship with job satisfaction in all fields. Job characteristics such as feedback, job characcteristics such as job autonomy, feedback and friendship were positively correlated with job satisfaction. The group of dietitians with high work value scores for work as a central life interest had significantly high scores in organizational commitment(p<0.01) and overall job satisfaction(p<0.05). Job satisfaction such as work-itself, pay, supervision, promotion and co-workers were positively correlated with organizational commitment. According to the Lisrel program, organizational commitment was affected by educational level(-0.23). Job satisfaction was also affected by educational level(-0.18), autonomy(0.24), friendship(0.12), feedback(0.08), individualism(-0.07) and organizational commitment(0.44) directly. In conclusion, school foodservice dietitians may increase the level of their commitment to organization and job satisfaction by increasing autonomy, feedback adn friendship of job characteristics and work values.

Most advanced countries that are members of the World Physiotherapy have established a 4-year education system or specialized graduate school system for physical therapists based on national standards. They have also expanded their laws and systems to provide physical therapists with the autonomy and independence to offer services in their clinics. However, compared with developed countries in North America and Europe, there are issues with the autonomy and independence of physical therapists in Korea related to national regulations. Social status and recognition of the profession are also lagging. Korea is expected to become a super-aged society by 2025. To reduce the financial burden of healthcare and welfare on the government, it is necessary to extend the time spent by older adults on independent activities and minimize their time spent using medical services. To achieve this goal and maximize the active life of older adults, a plan to efficiently use licensed physical therapists in the country should be prepared. Korea should increase the license utilization rate of physical therapists to reduce waste at the national level and increase the professional hope of the younger generations of physical therapists. To create a healthcare policy focusing on the use of physical therapy personnel, similar to that in advanced countries, it is necessary to unify educational systems and produce excellent physical therapists. Providing professional autonomy can help physical therapists develop a sense of job satisfaction. Outstanding talent will choose physical therapy as a profession if they can see hope for their future careers, and if physical therapy services in Korea are similar to those delivered in advanced countries, physical therapy in Korea can develop into a healthcare service that people desire.

The purpose of this study was to investigate the needs for exercise of adult inpatients and ultimately to provide basic data for planning nursing intervention of patients who need exercise. The tool used for this study was a structured questionnaire which consisted of 42 items. The test items were classified into seven factors. The seven factors of the needs for exercise were need for achievement, need for activity, need for affiliation, need for autonomy, need for catharsis, need for homeostasis, and need for exhibition. Subjects of this study were 127 patients in two general hospitals in Seoul, and one general hospital in Chun Ann City. The needs of exercise were identified and the data were analyzed by gender, age, occupation, education level, monthly income, size of patient room, patient group who requires exercise and the other patient group who requires bed rest, using one-way ANOVA and Scheffe test as post-hoc. The findings of this study were as follows ; 1) Among the needs for exercise of adult patients, the highest level of the needs was the need for homeostasis. The next highest was the need for achievement, then need for activity, need for catharsis, need for autonomy, need for affiliation, and the lowest was the need for exhibition. 2) Maintaining physical fitness stood first in the need for homeostasis, relieving psychological and physical powerlessness in the need for activity, mood diversion in the need for catharsis, happiness of the family in the need for affiliation, maintaining the balanced body figure in the need for exhibition, practicing planned life in the need for achievement, and improving the ability to overcome the crisis in the need for autonomy. 3) Male patients exhibited the higher level of the needs than female patients in all factors except the need for exhibition and homeostasis. 4) There was no statistical difference in the needs between age, occupation, monthly income, and the size of patient room. 5) The need for achievement was high as the level of education goes higher. 6) The patients who performed regular exercise before admission had higher needs for activity, achievement, and autonomy, compared with the patients who did not perform the regular exercise before admission. 7) There was no statistical difference in the needs between patient group who requires exercise and the other patient group who requires bed rest. The need for homeostasis was the highest in both groups. The results from this study suggest that the need for exercise of adult inpatients should be assessed before planning exercise intervention.

The purpose of this paper is to empirically analyze the determinants of foreign subsidiary's local embeddedness because it is critically important for the subsidiary to build a variegated local network. This paper suggests that a MNC's global capability, the degree of autonomy granted by the headquarters of the multinational corporation to its foreign subsidiary, the foreign subsidiary's absorptive capacity based on local environment, and its level of localization will affect the subsidiary's local network embeddedness. The empirical analysis confirmed that when the headquarters gives the foreign subsidiary more autonomy, this has a positive effect on the local embeddedness of the foreign subsidiary and when the foreign subsidiary has a strong absorptive capacity, this has a positive correlation with the local embeddedness of the foreign subsidiary. And this paper found that when the foreign subsidiary has achieved a high level of staff localization, this foreign subsidiary will have a higher level of local embeddedness. This study identified the preceding conditions necessary for a foreign subsidiary of a multinational corporation to effectively embed itself in the local network by analyzing factors related to the multinational corporation's headquarters and subsidiaries, and thus contributes significantly to continued research on the local embeddedness of subsidiaries.

In the field of on-road motor vehicles, the level for autonomous driving technology is defined according to J3016, proposed by Society of Automotive Engineers (SAE) International. However, in the field of agricultural machinery, different standards are applied by country and manufacturer, without a standardized classification for autonomous driving technology which makes it difficult to clearly define and accurately evaluate the autonomous driving technology, for agricultural machinery. In this study, a method to classify the autonomy levels for autonomous agricultural machinery (ALAAM) is proposed by modifying the SAE International J3016 to better characterize various agricultural operations such as tillage, spraying and harvesting. The ALAAM was classified into 6 levels from 0 (manual) to 5 (full automation) depending on the status of operator and autonomous system interventions for each item related to the automation of agricultural tasks such as straight-curve path driving, path-implement operation, operation-environmental awareness, error response, and task area planning. The core of the ALAAM classification is based on the relative roles between the operator and autonomous system for the automation of agricultural machines. The proposed ALAAM is expected to promote the establishment of a standard to classify the autonomous driving levels of self-propelled agricultural machinery.
