Anomaly detection in human movements can improve safety in indoor workplaces. In this paper, we design a framework for detecting anomalous trajectories of humans in indoor spaces based on a variational autoencoder (VAE) with Bi-LSTM layers. First, the VAE is trained to capture the latent representation of normal trajectories. Then the abnormality of a new trajectory is checked using the trained VAE. In this step, the anomaly score of the trajectory is determined using the trajectory reconstruction error through the VAE. If the anomaly score exceeds a threshold, the trajectory is detected as an anomaly. To select the anomaly threshold, a new metric called D-score is proposed, which measures the difference between recall and precision. The anomaly threshold is selected according to the minimum value of the D-score on the validation set. The MIT Badge dataset, which is a real trajectory dataset of workers in indoor space, is used to evaluate the proposed framework. The experiment results show that our framework effectively identifies abnormal trajectories with 81.22% in terms of the F1-score.

Purpose : This study examines the differences in self-efficacy and health promoting behavior between obese students and normal weight students by gender; it tries to obtain basic data for the health guidance of obese students. Methods : Data were collected from 360 students (90 normal weight males, 90 obese males, 90 normal weight females, 90 obese females) using questionnaires about general characteristics, self-efficacy, and health promoting behavior. There were analyzed with descriptive statistics (frequency, percentage, mean, standard deviation), and a x$^2$ test, ANCOVA, and a Pearson's correlation of coefficient at the 0.05 significance level by using the SAS (version 8.01) Win Program. Results : The score of self-efficacy appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=25.85, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=.01, p=.9118). The score of health promoting behavior appears that in the case of boys, obese students are significantly lower than their normal weight counterparts (F=28.61, p=<.0001), while in the case of girls there is no significant difference between the two groups (F=1.25, p=.2643). The relation of self-efficacy and health promoting behavior shows a statistically significant correlation in all cases: obese boys (r=.69, p=<.0001), normal weight boys (r=.51, p=<.0001), obese girls (r=.67, p=<.0001), and normal weight girls (r=.49, p=<.0001). Conclusions : An evaluation study needs to see whether a program to encourage the self-efficacy of obese boys can be effective in health promoting behavior or weight control in the long run. As in this study more than half of the obese girls have mild-level obesity, a follow-up study should be conducted to examine the self-efficacy and health promoting behavior between middle or highly obese students and normal weight students.

This study was to explore the level of self-actualization of the students in Korea Air and Correspondence University. The study subjects consisted of 507 students who visited the counseling center for taking advices to several psychosocial problems due to distance education through nursing counseling. The self actualization of the subjects evaluated by the self-actualization Inventory standardized by Kim and Lee in Korea. It consisted of 130 two-choice comparative value and behavior judgements. The items also consisted of two basic scales: one is inner directed scale (107 items) and the other is time competence (23 items) which included eight subscales, each of which measures a conceptually important element of self-actualization. Analysis of finding was as follows: 1) The self-actualization mean score of the total subjects was characterized by normal value within normal range of scale. The highest subscale score was NC scale: the lowest scale was EX scale. 2) The mean score of time competence scale of female student was higher than male student's time competence scale. 3) There was no significant differences in self aclualization among 4 groups in age. 4) There was also no significant differences in self-actualization between the group taken one time nursing counseling and the group taken two more times nursing counseling. 5) The problems of Job, learning, personality and further study, significantly had effects on the score of self-actualization level.

Purpose: The purpose of this study was to identify the self image according to body mass index in middle school students. Methods: The study included 260 students. Self image was measured using structured questionnaires. Statistical analysis was performed using t-test, ANOVA, Scheffe's test and multiple regression analysis. Results: The proportions of under weight, normal weight, and overweight were 36.1%, 53.9%, 10.0% respectively. Also, the mean of the self image score was 4.0. The score of self image was significantly higher in the normal weight group than the over weight group or the under weight group. This trend was also consistent in multiple regression. The score of self image was lower in high school grades, low perceived record, under-weight and over-weight. Conclusion: This study shows that many students are under weight. The score of self image was related with body image. So, level of obesity in each student should also be considered, to elevate the self image.

In an attempt to take Comprehensive nursing care the author tested cognitive function and psychiatric disturbance produced by normal adults. Mini-mental state and simple reaction time were tested and general health questionnaire was conducted two hundred subjects. The data were analyzed statistically and the results follow: 1. The score of mini-mental state of the elderly group was less significant than that of the younger group in the tests of cognitive dysfunction. The score of MMS of the female group, the illiteracy group less significant than that of other groups in the test of cogntive dysfunction. 2. Reaction time of the elderly group was slower than that of the younger group. Reaction time of the female group was slower than that of the male group. Reaction time of the illiteracy group was the slowest & the unskilled group was slower than that of the other groups. 3. As a result of the results of psychiatric disturbance the score of general health questionnaire of the elderly group was significantly higher than that of the younger group in the tests of psychiatric disturbance. The test of psychiatric disturbance sho-wed that the score of general health questionnaire of the female group was significantly higher than that of the male group in the tests of psychiatric disturbance. The illiteracy group was the highest in the psychiatric disturbance among other groups and the unskilled group was significantly higher than the other groups. 4. Education had higher correlation to mini-men-tat state, while age negative correlation in comparison with other variables age had higher correlation to reaction time, while education had negative correlation in comparison with other variables. Sex had low correlation in these tests.

Objectives : This study examined the reliability and validity of the Korean version of Asperger Syndrome Diagnostic Scale (K-ASDS), to calculate the cut-off score in the diagnosis of Asperger syndrome. Further, we examined classification error rate when applying cut-off scores. Methods : One hundred sixty-seven children participated in this study, including 46 with Asperger syndrome, 26 with PDD or PDD NOS, 43 with ADHD, and 52 normal children. Results : An ANCOVA demonstrated no significant differences in the K-ASDS total score between the Asperger and the PDD & PDD NOS groups. However, these groups did show significantly higher scores than the ADHD and normal groups. Among the five subscales on the K-ASDS, the Asperger group obtained significantly higher scores on the language and cognition subscales than the PDD & PDD NOS groups. Two scales were found to be useful in distinguishing the Asperger group from the PDD & PDD NOS group through a discriminant analysis. According to an analysis of ROC curve, the cut-off score on the K-ASDS for the diagnosis of PDD including Asperger syndrome was 121. Conclusion : We discussed that K-ASDS has pretty limit.

Objectives: The purpose of this study is to evaluate the clinical effects of Muscle Energy Technique (MET) for peroneal nerve palsy after normal delivery. Methods: Two patients with peroneal nerve palsy were treated with acupuncture, moxibustion, cupping and MET. MET was performed in piriform, gluteus medius, anterior tibial and adductor muscles. To evaluate the effect of MET, we analyzed Ankle dorsiflexion range of motion (ROM), Manual Muscle Test (MMT), Numerical Rating Scale (NRS) and Ankle Hindfoot Scale (AHS). Results: In Case 1, ROM score was changed from −5 to 20, and MMT score was changed from 0 to 4. NRS score was changed from 5 to 1, and her AHS score was changed from 54 to 94 after treatment. In Case 2, ROM score was changed from 0 to 20, and her MMT score was changed from 1 to 5. NRS score was changed from 4 to 1, and her AHS score was changed from 64 to 97 after treatment. Conclusions: MET may be a useful treatment for patients who, shortly after childbirth or while breastfeeding, strongly refuse to treat the irritation.

The purposes of this study are to develop 'Squat Scoring Scale' and identify relationship between squatting score and flexibility of the lower extremity muscles such as quadriceps femoris and soleus in terms of relationship between squatting and functions of lower extremity. Subjects have normal gait patterns only with or without musculoskeletal problems of lower extremities, lumbar and pelvis and gender. There are sixty subjects who participated in this study. The scoring are checked after squatting posture according to 'Squat Scoring Scale', and measured ROM of the ankle dorsiflexion and knee flexion for flexibility of the soleus and quadriceps femoris, respectively. Fourteen of sixty subjects have 10 score, seventeen subjects have 9 score, seven subjects have 8, 7 and 6 scores, three subjects have 5 score, and five subjects have 4 score. The gap between 10 to 9, 9 to 8 and 8 to 7 score in all values of angles has the statistical significance for t-test(p<.05). This information indicates that flexibility of quadriceps femoris and soleus acts as important factors in squatting.

This study was conducted to investigate the effect of integrated pest management (IPM) with 3point 5score microscopic monitoring method for laying farms infected with poultry red mites. A total of 8 laying farms infected with poultry red mites were divided into two treatments: 1) integrated pest management with 3point 5score microscopic monitoring method and 2) normal pest management with 3point 5score microscopic monitoring method. The results revealed that there is no significant difference between the groups with respect to the score of poultry red mites not only regardless of disinfection for the laying farms but also from week 4 to week 20 (P>0.05). However, the farm with IPM had a lower (P<0.05) score than those with the normal pest management method on week 24. Based on the result of the present study, controlling the presence of poultry red mites using IPM, along with consistent monitoring and supplementation using the 3point 5score microscopic monitoring method, is deemed effective in reducing the ultimately targeted infection rate of poultry red mites.
