Purpose: The purpose of this study was to investigate the effects of extracorporeal shock-wave therapy (ESWT) on pain, grip strength, and upper-extremity function in patients diagnosed with lateral epicondylitis and to provide an effective intervention method for lateral epicondylitis. Methods: Twenty patients with lateral epicondylitis were randomly assigned to the ESWT group (n = 10) and the stretching exercise group (n = 10). Interventions in both groups were performed six times twice a week for three weeks. The visible analog scale (VAS) was used to measure pain change. A dynamometer was used to measure grip strength (GS). Patient-rated tennis elbow evaluation (PRTEE) was used to measure the upper-extremity function. Results: There were significant differences in pain, grip strength, and upper-extremity function in both groups before and after intervention (p < 0.05). There were also significant differences in pain, grip strength, and upper-extremity function between the groups after intervention (p < 0.05). Conclusion: This study showed very positive improvement in pain, grip strength, and upper-extremity function after ESWT in patients with lateral epicondylitis. Therefore, ESWT can be recommended for patients with lateral epicondylitis.

Energy deficiency and global warming has become a serious issue in the world. Excessive dependency on fossil fuel is one of the major reasons for this so the alternative sources of energy need to be promoted and developed. Biomass to energy could be a better option where the conversion of the waste biomass to fuel could be a prominent solution for energy and environmental point of view. Thus, this study used torrefaction to improve the fuel characteristics of spent coffee ground (SCG). Spent coffee grounds are the waste (residue) generated during the brewing process of coffee. Torrefaction is an emerging thermal biomass pretreatment method that helps in increasing the fuel characteristics of biomass. The torrefaction of SCG was investigated in a horizontal tubular reactor at a temperature of 250, 270, 290, 310, 330 & 350℃, for the residence time of 0, 10, 20 & 30 mins. The torrefied products were characterized and analyzed in terms of their energy yield, mass yield, calorific value, elemental composition, cell structure, etc. The gaseous products from the torrefaction of SCG were also analyzed. Furthermore, the study reveals that the carbon content increases &oxygen content with an increasing torrefaction temperature which helps in increasing the fuel characteristics of SCG.

This study examines the influences of parental psychological control on the tendency for smartphone addiction and investigates whether adolescents’ relational aggression mediated the relation of parental psychological control on the tendency for smartphone addiction in adolescents. The sample for this study was 374 students (M 196, F 178) from four middle schools located in Seoul and Gyeonggi-do. Variables were measured with the Psychological Control Scale-Youth Self Report (PCS-YSR), the Peer Conflict Scale (PCS), and the Smartphone Addiction Diagnostic Scale (S-scale). The data were analyzed by means of descriptive statistics analysis, one-way ANOVA, correlation analysis, multiple regression analysis, and the Sobel test. Also, the Baron and Kenny’s model (1986) was used to verify mediating effects. The results are as follow. First, differences in the tendency for smartphone addiction according to gender, the period when participants started using their own smartphone, activities performed most by smartphone, hours of smartphone use per day on weekdays, and hours of smartphone use per day on weekends were significant. Second, parental psychological control, relational aggression, and all subvariables of the tendency for smartphone addiction showed a significant positive correlation. Third, relational aggression turned out to mediate partially between both maternal and paternal psychological control and all subvariables of the tendency for smartphone addiction. The results of this study show that parental psychological control has direct and indirect effects on the tendency for smartphone addiction and describe the mediating effects of relational aggression
서비스 기업의 디자인 경영 활동 정보 시각화에 관한 연구 - 기업 웹사이트의 내용분석을 중심으로 -

과거 기업의 디자인경영은 제품디자인 위주로 이루어졌으나, 시각, 공간, UX 등으로 디자인 범주가 확대되고 있으며, 제조업에서 서비스업으로 그 경계가 확장되고 있다. 한편 인터넷의 발전과 더불어 대부분의 기업들은 고객이 필요로 하는 정보의 욕구를 충족 시키고자 기업 웹사이트를 적극적으로 활용하여 기업 정보를 제공하고 있다. 본 연구는 국내의 디자인 경영을 우수하게 수행하고 있는 서비스 기업의 웹페이지에 나타난 디자인 경영의 활동 및 성과에 대한 정보 시각화의 현황을 분석하여 구체적인 방안을 제시하는데 그 목적이 있다. 연구방법으로 내용분석방법을 진행하였으며, 연구대상은 대한민국디자인대상을 받은 서비스 기업으로 한정하였다. 그 결과 디자인 경영 활동은 전략적 차원과 전술적 차원에 비해 실행적 차원의 활동 정보가 적극적으로 전달되고 있으며, 디자인 경영 성과의 정보도 다양한 표현방식으로 시각화되고 있었다. 결론으로 각 디자인 경영의 차원별 활동과 성과로 구체화된 정보시각화 방안을 제안하였다. Previously, the design management was only focused on the product design but recently the scope of this area has been expanding to graphic, environment, UX and even from manufacturing industries for developing service industry. Many of companies that to fulfill the customers`` demands have used the homepage by enhancing the internet technologies. The aim of this research is to identify strategic implications for information visualizing and communicating method in design management activities by analyzing the website contents of selective companies which shown good design management practices. The method of research adopted content analysis method and research targets were mostly service companies that won a prize in the "Korea Design Award". As a result, design management activities are actively expressed in operational level rather than strategic and tactical level, and the Information of design management performance is visualized with more various graphic methods. In conclusion, this research provides ways of information visualization methods in the activities of three design management levels and outputs.
