Physical conditions play vital role on the mechanical properties of frozen soil, especially for the temperature and moisture content of frozen soil. Subsequently, they influence the subsidence and stress law of permafrost layer. Taking Jiangcang No. 1 Coal Mine as engineering background, combined with laboratory experiment, field measurements and empirical formula to obtain the mechanical parameters of frozen soil, the thick plate mechanical model of permafrost was established to evaluate the safety of permafrost roof. At the same time, $FLAC^{3D}$ was used to study the influence of temperature and moisture content on the deformation and stress law of frozen soil layer. The results show that the failure tensile stress of frozen soil is larger than the maximum tensile stress of permafrost roof occurring in the process of mining. It indicates that the permafrost roof cannot collapse under the conditions of moisture content in the range from 20% to 27% as well as temperature in the range from $-35^{\circ}C$ to $-15^{\circ}C$. Moreover, the maximum subsidence of the upper and lower boundary of the overlying permafrost layer decreases with the increase of moisture content in the range of 15% to 27% or the decrease of temperature in the range of $-35^{\circ}C$ to $-15^{\circ}C$ if the temperature or moisture content keeps consistent with $-25^{\circ}C$ or 20%, respectively.

Objective: This study was at investigated the effects of manual lymphatic drainage (MLD) on stress and pain in patients with postoperative breast cancer. Design: A randomized controlled trial. Methods: A total of twenty-two patients with postoperative breast cancer voluntarily participated in the study. Subjects were randomly assigned to the MLD groups (n=12) and rest groups (n=12). The intervention was conducted in each group for twenty minutes a day, five times a week, for four weeks. Before and after the intervention, the participants measured sympathetic nerve, parasympathetic nerve, and pain by using a sphygmograph and short-form McGill pain questionnaire.An independent t-test was used to analyze pretest and posttest changes between the groups, a paired t-test was used to analyze pre-posttests within each group. Results: After analyzing, the MLD group has been shown a significant decrease in the sympathetic nervous system (p<0.05), a significant increase in the parasympathetic nervous system (p<0.05), and a significant increase in pain (p<0.05). However, the rest group was no significant difference between pre and post. Conclusions: The results of this study confirmed that MLD techniques are an effective method in reducing stress and pain in patients with postoperativebreast cancer. And it is thought that can be used as basic data and to develop programs on stress and pain management reduction for patients with breast cancer.

The aim was to evaluate the prevailing ergonomic and psychosocial conditions regarding low back injury in an automobile assembly system. This study consisted of two parts. In the first part of the study, analytic biomechanical model and NIOSH guidelines were applied to evaluate risk levels of low back injury for automobile assembly jobs. Total of 246 workers were analysed. There were 20 jobs having greater back compressive forces than 300kg at L5/S1. Also, there were 44 jobs over Action Limit with respect to 1981 NIOSH guidelines. This might in part be explained by the ergonomic conditions of the company analysed generally being good, with a relatively low duration of 'combined' extreme work posture. The relationship between psychosocial factors and low back injury was examined in the second part of the study. It has recently been recognized that overall reaction to working conditions was influenced by a range of factors, some of which were physical and some psychosocial. The psychosocial environment surrounding the work place may contribute to the perception of risk and eventual ill-health. A battery of questionnaires concerning the psychosocial stress based on PWI(Psychosocial Well-being Index) and musculoskeletal pain symptoms at low back was completed by 246 workers at the same plant. Results showed that 207 out 246 workers experienced the symptoms and 27 workers were diagnosed as patients. Two groups(low stressed, high stressed) based on PWI score had no significant relationships with both symptoms and results of diagnosis. However, sensitivities for symptoms and diagnosis by PWI were 91.3% and 92.6% respectively. Finally, relationships between physical work load and psychosocial stress were analysed. Specifically, some postural factors {vertical deviation angle of forearm, horizontal deviation angle of upperarm, vertical deviation angle of thigh, etc) were highly correlated with psychosocial stress. The results illustrated that PWI scores were associated with some physical workloads. However, psychosocial stress levels couldn't be well related with the pain symptom as well as the actual incidence of low back injury since pain or discomfort regarding low back injury were more complex than that of other musculoskeletal disorders.

The purpose of this study is to investigate musculoskeletal symptoms and job stress of physical therapists in their 20s who are responsible for therapeutic exercise and to understand the correlation between the two. This study conducted a research on 144 subjects based on the measurement tools provided by national institution. The results are as follows. Many subjects were experiencing musculoskeletal symptoms and disorder in their hands/wrists/fingers, shoulders, and waist with high proportionate of subjects experiencing the symptoms and disorder in their right hand/wrist/finger. Among job stress, job environment, job requirement, and compensation had significantly positive correlation with physical burden(r=.297~.392, p=.000). In particular, shoulder pain intensity has significantly positive correlation with job requirement, duration of pain in hand, wrist, and fingers as well as workplace culture(r=.331~.478, p=.003~.009) which indicates that musculoskeletal symptoms are some what correlated with job stress. Based on this study, it is necessary to show more concern and make an effort to manage musculoskeletal symptoms and job stress.

The purpose of this study was to investigate the relations between financial stress, depression, and conjugal affection and the motivation for rehabilitation. One hundred eighty-six stroke patients were included in the study and a survey with 65 questions was used. The survey includes questions to evaluate personal factors, characteristics related with physical therapy, characteristics related with disease, depression, conjugal affection, and motivation for rehabilitation. Education, employment, left hemiplegia and right hemiplegia, depression, financial stress, conjugal affection were statistically significant factors (p<.05). These variables have significant effects on motivation for rehabilitation. This study indicates that financial stress and depression need to be decreased to improve motivation for rehabilitation of stroke patients. It also indicates that the factors facilitating conjugal affection, education, and occupation need to be considered for rehabilitation programs.

This study was performed to investigate the effects of academic stress and academic burnout on smartphone addiction in junior high school students. A survey was conducted using a convenient sample drawn from 306 students at six junior high schools in Seoul. Data were analyzed using the SPSS 23.0 program. The results show that 21.6% of students were at risk of smartphone addiction. The high risk of smartphone addiction group used smartphone longer during weekdays and weekends. In addition, the high level of academic stress and academic burnout groups showed higher smartphone addiction scores compared to the lower level of academic stress and academic burnout groups. Smartphone addiction was positively correlated with academic stress and academic burnout. Furthermore, the results show that academic achievement and attending class, academic stress and disengagement, and academic burnout affected smartphone addiction. Therefore, to prevent smartphone addiction in adolescents, academic stress should be reduced in adolescents as well as develop educational programs to help students release or control their academic stress.
