As workplace incidents has been being declining in Korea, there is criticism of the effectiveness of occupational safety policy implementation. It is unknown that which policy target group needs to be targeted to yield effective injuries prevention. The purpose of this paper is to analyze and reveal the policy intervention group with a high priority in terms of industrial incident prevention and the related investment cost. A Policy Priority Model(PPM) is composed of 6 indicators regarding influences of both the incident reduction and the cost reduction. Z-score analyses are used to confirm the high policy priority area or policy target group. Overall, workplace with worker below 50 persons, construction site with the sales of more than a hundred million won, workplace with relatively small percentage of female employees and relatively higher percentage of older worker should be prioritized to reduce workplace injuries. This paper provides an analytic way that can be used to decide the policy priority workplace in order not only to reduce work-related injuries&illnesses and the related investment cost but to further lessen the related societal costs.

Purpose: The purpose of this study was to analyze emotional labor factors influencing job satisfaction, intent to leave, and nursing performance of clinical nurses. Method: The participants were 384 clinical nurses working in a hospital. Study design was cross sectional survey. Subcategories of emotional labor (frequency of emotional labor, attentiveness of emotional display, mismatch of emotions) of emotional labor were dependent variables. Job satisfaction, intent to leave, and nursing performance were independent variables. Data were analyzed by hierarchial multiple regression. Results: The strength of emotional labor of nurses was similar for all participants in spite of differences in age, position, and clinical career. Total score for emotional labor was 3.21, frequency of emotional labor 3.34, attentiveness of emotional display 3.41, and mismatch of emotions 2.87. Mismatch of emotions influenced job satisfaction (F=12.53, p<.001) $R^2$ 27%, intent to leave (F=8.51, p<.001) $R^2$ 19%, and nursing performance (F=5.80, p<.001) $R^2$ 15%, Conclusion: These findings indicate that the factor (mismatch of emotion) is an important variable for clinical nurses in human resource management. Therefore, nurse managers should consider this factor for the improvement of organizational effectiveness.

The inspection of cracks on the surface of tunnel linings is a common method of evaluate the condition of the tunnel. In particular, determining the thickness and shape of a crack is important because it indicates the external forces applied to the tunnel and the current condition of the concrete structure. Recently, several automatic crack detection methods have been proposed to identify cracks using captured tunnel lining images. These methods apply an image-segmentation mechanism with well-annotated datasets. However, generating the ground truths requires many resources, and the small proportion of cracks in the images cause a class-imbalance problem. A weakly annotated dataset is generated to reduce resource consumption and avoid the class-imbalance problem. However, the use of the dataset results in a large number of false positives and requires post-processing for accurate crack detection. To overcome these issues, we propose a crack detection method using a ternary classifier. The proposed method significantly reduces the false positive rate, and the performance (as measured by the F1 score) is improved by 0.33 compared to previous methods. These results demonstrate the effectiveness of the proposed method.

Purpose: This study was to identify the effectiveness of high-intensity laser therapy on pain and function of a frozen shoulder. Methods: Thirty patients were assigned to two groups: the experimental group (n=15) and the control group (n=15). Both groups received traditional therapy for 4 weeks, 3 days a week. The experimental group, however, received an additional high intensity laser therapy. Pain was measured using the visual analogue scale (VAS). The functional ability was measured using the patient specific functional scale (PSFS). A paired t-test was used to determine any differences before and after the treatment, and an independent t-test was used to determine any differences between treatment groups. Results: Both groups showed a statistically significant difference for VAS and PSFS score (p<0.05). In comparison between two groups, more experimental group than control group statistically significant difference (p<0.05). Conclusion: There seems to be a positive effect on pain and function of frozen shoulder from using high intensity laser therapy.

Objective: This study was designed to investigate the effect of Wihwa herbal-acupuncture on chronic gastritis. Methods: Wihwa herbal-acupuncture was administered two times a week. The following points were selected: CV12(中脘), CV13(上脘), S36(足三里), Liv3(太衝). We checked pain rating score(P.R.S.), visual analogue scale (V.A.S.) and Gastroscopy. Results: After 6 weeks of treatment, the patient showed that clinical symtoms was disappeared, Lee's P.R.S. changed from 77 to 8 and Park's P.R.S. from 55 to 0 and gastric erosion disappeared on gastroscopy. Conclusions: These results suggest that and Wihwa herbal-acupuncture has good effect on chronic gastritis. But further studies are required to concretely prove the effectiveness of Wihwa herbal-acupuncture for treating chronic gastritis.

Web-scale open information extraction (Open IE) plays an important role in NLP tasks like acquiring common-sense knowledge, learning selectional preferences and automatic text understanding. A large number of Open IE approaches have been proposed in the last decade, and the majority of these approaches are based on supervised learning or dependency parsing. In this paper, we present a novel method for web scale open information extraction, which employs cosine distance based on Google word vector as the confidence score of the extraction. The proposed method is a purely unsupervised learning algorithm without requiring any hand-labeled training data or dependency parse features. We also present the mathematically rigorous proof for the new method with Bayes Inference and Artificial Neural Network theory. It turns out that the proposed algorithm is equivalent to Maximum Likelihood Estimation of the joint probability distribution over the elements of the candidate extraction. The proof itself also theoretically suggests a typical usage of word vector for other NLP tasks. Experiments show that the distance-based method leads to further improvements over the newly presented Open IE systems on three benchmark datasets, in terms of effectiveness and efficiency.

Objective : The purpose of this study is to find out the effectiveness of Ling-Gui-Gan-Zao-Tang for patients of panic disorder. Method : To achieve the purpose of this study, Ling-Gui-Gan-Zao-Tang was prescribed for three months to two different patients of panic disorder. They were diagnosed as panic disorder in department of neuropsychiatry, and had no other prescribed decoction or psychotherapy. Results : 1. The BAI score for anxiety were decreased in both patients, and they got improved overall symptoms. 2. In panic attack, patients are in dominant state of sympathetic nerve, so they have palpitaion and get nervous. Fu-Ling(茯笭) can treate this kind of situation. 3. Based on and , urgent situation, over-tension of muscles, hot flash can be treated Gancao(甘草), Dazao(大棗), Guizhi(桂枝) respectively. Conclusions : When panic disorder attaks, the sympathetic nerves are dominant in patient's body. So they feel palpitating, sweating, suffocating. Ling-Gui-Gan-Zao-Tang can treat this series of symptoms.

The purpose of this study is to report the effectiveness of diarrhea-inducing treatment by Gamsui-mal for lumbar spinal stenosis. During hospitalization four patients with lumbar spinal stenosis were treated with diarrhea-inducing treatment by Gamsui-mal and acupuncture, herbal medicine, moxibustion, cupping treatment, Bee-venom pharmacopuncture. Before treatment, we explained in detail about diarrhea-inducing treatment by Gamsui-mal and patients agreed with treatment. The symptoms appeared in patients of diarrhea, abdominal pain, and vomiting in the treatment process. We evaluated the degree of improvement by visual analogue scale (VAS), oswestry disability index (ODI). After treatment, we found that pain was reduced and patient's symptoms were improved by visual analogue scale (VAS), oswestry disability index (ODI) score. The results show that diarrhea-inducing treatment by Gamsui-mal was rapidly improving symptoms. Further studies are needed to clarify the effect of diarrhea-inducing treatment by Gamsui-mal.
