  • The present study evaluated the effects of fermented whey protein using kimchi lactic acid bacteria Lactobacillus casei DK211 on skeletal muscle mass, muscle strength, and physical performance in healthy middle-aged males performing regular resistance exercises. Effective protein supplementation and regular exercise are two important factors for improving muscle health. Therefore, in this study, the effects of consuming fermented whey protein twice a day were investigated and compared with that of non-fermented supplementation. Forty-eight males (average age 44.8) were randomly assigned to two groups: Fermented whey protein supplementation (FWPS) and non-fermented whey protein concentration supplementation (WPCS) groups. Each group ingested 37 g of FWPS or WPCS twice a day for eight weeks. Body composition, muscle strength, and physical performance were assessed pre- and post-intervention. Independent t-tests or chi-square tests for the categorical variables were performed for analyzing the observations. FWPS was effective in promoting the physical performance in dynamic balance measurement and muscle health, indicated through the increment in grip strength (left), upper arm circumference, and flat leg circumference from the baseline. However, similar improvements were not observed in the WPCS group. These results imply that whey protein fermented by L. casei DK211 is an effective protein supplement for enhancing muscle health in males performing regular resistance exercises.

  • The purpose of this study was to develop an e-textile using LEDs that can enhance visual and functional effects, and to identify their applicability to sportswear. By applying the design elements of fashion design concretely with LEDs, an e-textile design module is developed and that module is applied to the product, so LED application design can be proposed for use in a practical product. E-textiles have been divided into five categories, and their usefulness were verified by applying e-textiles to men's and women's sportswear. The product beign considered has a built-in tilt sensor, which illuminates the LEDs according to the user's movements, and allows the LEDs to be turned on or off in accordance to the user's preference. E-tatoo is a type of LED application that enhances the appearance by placing LEDs on a small area, emphasizing origin points, just like an actual tattoo. Designed with LEDs arranged in a straight line and various curved forms, e-strips can provide a function that matches the characteristics of each section of clothing or fashion item. E-wappen uses about 7-10 LEDs to give motifs a strong sense of visibility, thus adding to their vibrancy. E-panels and e-clothes were able to produce creative and high-value textures. It is also expected to be used for special purposes or bags as it is possible to produce high value-added textures that are creative and aesthetically beautiful. For instance, a progressive LED string on the straight line of female leggings can further emphasize rhythmic movements during exercise, and e-wappen also serves the purpose of nighttime protection. It is also believed that the application of dance or dance-related sportswear will make the movement of the performance more intense and lively.

  • This study aims to examine the level of students' satisfaction toward the services (i.e. accommodation facilities, transportation facilities, and recreation and sports facilities) provided by the public universities in Bangladesh. The study also aims to identify the major service factors that influence students' satisfaction in public universities in the country. A cross-sectional survey was conducted at six public universities to obtain primary data. A standardized questionnaire was distributed to a total of 500 randomly selected students to collect the data. Several statistical tools, namely, reliability analysis, descriptive statistics, correlation analysis and multiple regression analysis were employed to analyze the data. The findings revealed that recreation and sports facilities have the strongest impact on students' satisfaction in the public universities in Bangladesh. Transportation facilities also have positive and significant impact on student's satisfaction. However, the study found a negative correlation between accommodation facilities and students' satisfaction indicating that students are not satisfied with the accommodation facilities provided by the public universities. The findings of this study provide an insight about students' satisfaction that might be useful to authorities of the public universities and other higher educational institutions in designing policies for various services and facilities to be provided to their students.

  • The purpose of this study was to evaluate the effect of taping-tape with or without using spiral taping on vertical jump. The subjects for this study were about 20 years old healthy male college students without muscloskeletal diseases. Data for EMG activity and Ground Reaction Force(GRF) were estimated at three knee angles(i.e., 45, 90 & full degree). As a result, there was no statistical significance in max GRF at 90 and full degree regardless of spiral taping-tape. On the other hand, statistical significance was found when vertically jumping at 45 degree knee angle(p<.05). All the data for EMG activity at the three knee angles were not statistically significant, but there was a trend for a decrease in average EMG activity in elector spinae & Medial gastrocnemius at 90 degree knee angle. Based on these data, initial flexor action of knee was stabilized with spiral taping-tape when vertically jumping, resulting in improved muscular activity in Medial gastrocnemius. In conclusion, taping technique for jumping ability associated muscles like quadriceps is also required to develop.

  • In recent years, digital media providing entertainment and information have become an important channel of customer experience. The aim of this study is to evaluate the effects of digital signage's characteristics on flow and brand attitudes and to verify the mediating role of pleasure in digital signage and flow. The stimuli were developed for a sports brand stores using 3D and video editing software. The survey was conducted on 544 subjects from both gender aged 20 to 49 years old, i.e. the population that constitutes the major target group for sports brands. The data collected was analyzed using IBM SPSS 24.0. Specifically, frequency analysis, factor analysis, reliability analysis, t-test, and regression analysis were performed on the data. Based on the results, we can draw the following conclusions; First, the dimension of digital signage was classified into aesthetic and functional attributes. Additionally, we found out that women highly value aesthetic attributes of digital signage while the customers in their 40s pay more attention to functional attributes than their counterparts aged 20-30 years. Second, our results suggest that pleasure has a mediating effect in the relationship between digital signage attributes and flow; specifically, both sub-dimensions of digital signage features (aesthetic attributes and functional attributes) affect flow by means of pleasure. Third, our results demonstrated that the flow of digital signage had a significant impact on brand attitudes.

  • Objective: The purpose of this study was to analyze the effects of club head and golf ball kinematics and body alignment according to the swing plane during golf driver swing. Method: Sixteen college golfers participated in this study. Kinematic data of the club head and golf ball were collected using golf swing analysis system (Trackman Ver. 3e). The body alignment variables were collected using 8 motion capture system. An Independent samples t-test was used for comparison between the Out-to-In group and In-to-Out group, and the statistical significance level was set at .05. Results: For the club head related variables, club path and club face angle showed higher values in Out-to-In swing plane than In-to-Out swing plane. For the kinematic variables of the golf ball, the total distance showed a higher value in the In-to-Out swing plane than that of the Out-to-In swing plane. For the body alignment, the In-to-Out swing plane showed higher values than the Out-to-In swing plane for the pelvis rotation angle and trunk rotation angle. Conclusion: This study suggest that it would be more effective to use the In-to-Out swing plane for increasing the total distance during the golf driver swing.

  • 현재의 조명 산업은 반도체 LED를 이용한 R(빨강), G(초록), B(파랑)를 각각 제어 연출하여 대형화, 시스템화 되어가고 있다. 조명 산업의 통신 제어 표준인 DMX512(ANSI E1.11) 프로토콜은 기본적으로 조명 단말기를 구별할 수 있는 주소가 필요하다. 기존의 방식은 이 주소를 조명 단말기에 어떠한 형태(Dip Switch, EEPROM에 저장, PROM에 저장)로든 부여하여 서로를 구별하고, 통신으로 전송되어온 자신의 색상 데이터를 통신 선로에서 얻을 수 있었다. 또한, 통신 규약에 의하면 DMX512 통신 프로토콜의 전기적인 특성상 조명 단말기 32개 마다 스프리터(splitter)가 필요하게 된다. 즉, 512채널이 전부 연결된다면 최대 16개의 스프리터가 필요하게 된다. 본 논문은 DMX512 프로토콜에서 이러한 단점을 해결하기 위하여 모든 단말기를 직렬로 연결하여 조명제어용 Auto-Addressing 갖는 지능형 조명 단말기를 개발하였다. 각 단말기에 주소 부여에 대한 불편함을 해소하였고, 스프리터의 사용 또한 필요없게 하였다. 또한 이 개발품을 반도체 LED 조명 단말기에 적용하여, ON-OFF제어, 디밍제어, 순차제어, 무지개제어 등이 동작하는 것을 확인하였고, 이를 바탕으로 상용화하였다.
