        Background: The hip muscle plays various roles. Several types of functional performance tests are used for the assessment of patients with various lower extremity injuries. Hip muscle functions are important to test the performance of maintaining the spine, pelvic, and leg during bridging exercise. We designed a novel functional performance test tool, which we named close kinetic chain dynamic lower extremity stability (CKCLE) test to assess hip muscle functions. Objects: The purpose of this study was to determine the relationship between CKCLE test and hip extensor, external rotator, and abductor strengths. Methods: Twenty-two subjects were recruited in the present study (13 males and 9 females). The hip extensor, external rotator, and abductor muscle strengths were measured using a Smart KEMA strength sensor. When the examiner said “Go”, the subject performed the CKCLE test by moving one leg from the floor and touching the opposite knee and then return to the floor while maintaining the bridging position. The subjects attempted as many “touches” as possible in the allotted time (20 seconds) during the maximal tests. The correlation between the hip muscle (extensor, external rotator, and abductor) strength of the supporting leg and the number of CKCLE tests performed in 20 seconds was determined using the Pearson correlation. Results: Hip extensor (r = 0.626, p < 0.05), hip external rotator (r = 0.616, p < 0.05), and hip abductor muscle strengths (r = 0.475, p < 0.05) positively correlated with the number of CKCLE tests performed. Conclusion: We designed a CKCLE test and found that performance in the test correlated with hip extensor, external rotator, and abductor muscle strengths. The result suggests that the CKCLE test can be applied as a performance test to assess the functions of the hip extensor, external rotator, and hip abductor muscles.

        Background: Prolonged standing during work causes a lower extremity pain and disorders. Patellofemoral pain syndrome (PFPS) is one of the common diagnoses of the knee pain. Although the etiology of PFPS is not completely understood, it is considered to be multifactorial. Objects: The purpose of this study was to investigate difference in strength of knee muscles, quadriceps:hamstring muscles strength ratio (Q:H ratio), asymmetry ratio of knee muscles strength and dorsiflexion range of motion (ROM) between standing workers with and without PFPS. Methods: Twenty-eight standing workers with PFPS and 26 age-, height-, and weightmatched standing workers without PFPS participated in this study. A tension sensor measured knee muscle strength, and motion sensor measured dorsiflexion ROM. The asymmetry ratio of knee muscles was calculated by a specific formula using the knee muscles strength of the dominant side and the sound side. An independent t-test was used to identify significant differences in the strength, ROM, Q:H ratio, and asymmetry ratio between the PFPS and normal groups. Results: The standing worker with PFPS have significantly lower dorsiflexion ROM (p < 0.000) and higher asymmetry ratio of the hamstring muscles strength (p < 0.000) compare to the standing worker without PFPS. No significant differences were seen in the strength of quadriceps muscle and hamstring muscles, Q:H ratio, and asymmetry ratio of quadriceps muscle strength. Conclusion: There was a significant difference in the asymmetry ratio of the isometric hamstring muscle strength. This finding suggests that the asymmetry ratio of isometric hamstring muscle strength may be more important than measuring only the hamstring muscle strength of the PFPS side. Furthermore, the results of this study showed a significant difference in dorsiflexion ROM between the standing industrial workers with and without PFPS. Dorsiflexion ROM and isometric hamstring muscle strength should be considered when evaluating the subjects with PFPS.

        The purpose of this paper is to provide a critical overview of the use of social marketing in Asia. A total of 17 countries were included in this paper. We demonstrate the development and trends of social marketing in Asia by highlighting prominent and effective cases. Our findings reveal that social marketing practice represents a wide spectrum of topics. However, public policy and education outweigh adoption of social marketing to address social issues. Several barriers influence adoption and effectiveness of social marketing. We highlight a few and recommend strategies to overcome them.

        The current study uses risk theory to explore factors mitigating consumers’ intention to use SSTs. The findings of an empricial study reveal that the perceived time, security and addiction risk indirectly reduce consumers’ intention to use SSTs through the per-ceived psychological risk. Most importantly, this study’s findings show that an increas-ing autonomy of SSTs strengthens the effects of perceived addiction risk.

        This study enrolled enterprise business owners/managers in the U.S. as the subjects to investigate the relationship among four factors: personal motivation, the social expectation of stakeholders, business performance, and their CSR toward the local community. The research results showed that: (1) small enterprise’s perceived expectation from stakeholders has a positive effect on their decision to engage in CSR toward community; (2) their perception of business performance has a positive effect on their decision to engage in CSR toward the community. Based on these research results, public policymakers or relevant units are advised to further achieve the goal of nurturing a flourishing community by increasing awareness of stakeholder’s expectations for small enterprise’s CSR commitment. Also, it is clearly pronounced in this study that regardless of their personal motivation to support the local community, unless financially successful, small businesses are less likely to engage in CSR toward the local community. This result makes a good sense that having a successful business operation is a necessary condition for small enterprises to pay attention to a higher-level value such as CSR toward the local community.
