Piriformis syndrome is a common differential diagnosis related to sciatica. The following review provides a concise synopsis of the diagnosis, management, history, and alternatives to diagnosis of piriformis syndrome. A search of the literature for research articles related to piriformis syndrome and associated differential diagnosis of sciatica was conducted. A thorough review of the included articles found that the condition known as piriformis syndrome is over-diagnosed and that potential anatomic and biomechanical variations originating in the pelvic region might be related to the complaint of sciatica. The criteria for diagnosis are based on findings from both physical examination and radio imaging. Piriformis syndrome resembles a variety of clinical conditions; therefore, conduct of future studies should include development of a validated method for evaluation as well as clinical criteria for diagnosis of piriformis syndrome.

It's necessary to judge between success and failure of a project in order to secure the objective evaluation index and the transparency of that. In case of the public works including a construction section, the large-scale budget input proceeds, but the awareness regarding the efficiency and usefulness of the public works is decreasing because it's hard to estimate benefit originated from the results of the budget input. Therefore, this study is to propose the measurement standard for the post-evaluation based on the list of the resident response degree and user satisfaction degree to systematically and quantitatively measure the results of the post-evaluation for the public projects within the range of quantifying the consumer satisfaction degree for the facilities which preform the post-evaluation among the public projects with 50 billion budget.

Objectives The purposes of this study was to develope a Qi gong exercise that suits characteristics of post mastectomy women, and to evaluate the effect of Qi gong exercise on immune response, blood circulation index, pulse wave parameter and heart rate variability. Methods This study was applied to total 35 post mastectomy women, including 17 for experiment group and 18 for control group. The Qi gong exercise was composed of total 24 times of 90 minutes per each time, twice a week, and 12 weeks and it was conducted by the oriental medicine professor who was an expert of Qi gong exercise. Results 1. Two group comparison revealed that the experimental group had significantly improved immune response(p<.021), HR(beats/min)(p<.001), ESV(ml/beat)(p=.038), ESI($ml/beat/m^2$)(p=.040), ECO (L/min)(p=.019), ECI($L/min/m^2$)(p=.023), ECRI($dyne^*sec/cm$)(p=.015), Left Kwan($div^3$)(p=.021), Right Kwan($div^3$)(p=.038), Mean HRV(cycle/min)(p<.001), SDNN(ms)(p=.043), RMSSD(ms)(p=.040), and TP(log $ms^2$)(p=.039). 2. Two group comparison revealed that the experimental group had significantly decreased ECR ($dyne^*sec^*cm^{-5}$) (p=.034), Left RAI(p=.044), Right RAI(p=.042), and pNN50(%)(p=.038). Conclusions These results from Qi gong exercise program can be used as basic data for development of health promotion program for Post Mastectomy Women.

This paper presents a case study on BSC(Balanced Scorecard) system development of Korea Post as a Korean public firm. BSC models of public or private sector are generally developed in different types due to their different strategic goals. Korea Post as a government firm has dual characteristics of BSC similar to both public and private sector. This firm has the organizational type of public firms, not private firms. To date many government subsidiary organizations have already introduced BSC or are trying to introduce BSC, but have difficulty in developing BSC successfully because of insufficient understanding of BSC. Based on a case study of Korea Post, this study analyzed key success and failure factors and suggested prospects on BSC system development of public firms.

Purpose: The study aimed to determine the impact of post-traumatic stress and ways of stress coping on problem drinking in firefighters. Methods: Data were collected from May 11 to June 11, 2015, in fire brigades across South Korea. Participants were 183 male firefighters who used self-report questionnaires containing questions from the Impact of Event Scale-Revised (IES-R), Ways of Coping Checklist (WCC), and Alcohol Use Disorders Identification Test (AUDIT). Data were analyzed using $x^2$ test, t-test, and logistic regression with the SPSS/WIN 21.0 program. Results: The prevalence of PTSD among firefighters was 36.7% and that of problem drinking was 39.3%. Firefighters with single (OR=0.23, 95% CI=0.038~1.321) and married status (OR=0.46, 95% CI=0.069~3.040) were less likely to have problem drinking than those who were divorced or bereavement. Those with invasion symptoms (OR=1.17, 95% CI=1.031~1.327) and hyperarousal symptoms (OR=0.85, 95% CI=0.722~0.989) were more likely to have problem drinking than those with avoidance symptoms. Conclusion: Post-traumatic stress symptom was a major risk factor that increased problem drinking, and married status reduced problem drinking. There is a need to develop post-traumatic stress symptom management program and early education content for symptom management.

Recently, most tech-based products are of multiple generations, since new-generation products are replacing the older ones as technologies continue to improve. Although, this means that research is needed to examine as much about the role of post-adoption behavior as the missing link between the adoptions of successive generation as first adoption of innovation, there is a dearth of literature explicitly examining consumers' post-adoption behavior, especially in the context of subscription-based service. For the subscription-based services, in spite of the important role of consumer satisfaction, research on the post-adoption behavior can not carefully examine the direct impact of consumer satisfaction on their decision to upgrade by considering usage instead of satisfaction as the missing link between buyers' first adoption and their next-generation adoption. This study identified two types of attribute satisfaction such as basic attribute and core attribute using both literature review and FGI (Focus Group Interview), and tries to investigate how two types of attribute satisfaction has influence on customers' intention to upgrade to the next-generation services. and a moderating role of customer loyalty between attribute satisfaction and intention. The empirical results show that core-attribute satisfaction has a negative influence on customers' intention to upgrade, due to the moderating role of customer loyalty, but it can raise their intention to upgrade next-generation services. However, basic-attribute satisfaction, on the other hand, appears to positively influence both customer loyalty and the intention to upgrade. We also find that the consumer attribute satisfaction is influenced by consumer innovativeness, her perception of service and the usage of each features' type in different ways. Finally, academic and practical implication is made, limitation is clarified and a direction for further studies is suggested.

The purpose of this study was conducted to determine the working conditions, post-traumatic stress syndrome and the self-resilience of nurses, and find out the relationship between the post-traumatic stress syndrome and the self-resilience. Data were collected by questionnaire method among 220 General Hospital nurses at Gyeongnam G and J city. Data were analyzed by using SPSS 21.0 program WIN. The results of working conditions of the nurses majority were shift work 70.5%, currently working in the ward 54.6%. Scores were shown as Post-traumatic stress syndrome (28.20) and self resilience (39.98). There is a negative correlation (r =.226, p=.001) between the post-traumatic stress syndrome and the self-resilience. Based on the result, since working conditions of nurses caused psychological stress and nurses with high self-resilience eased the degree of post-traumatic stress, in terms of the personnel management of hospitals, a psychological intervention strategy should be considered.
