Purpose : The purpose of this study was to investigate, The Effects of Massage and Taping on Muscle Strength and Flexibility and Pain with Delayed Onset Muscle Soreness(DOMS). DOMS is a common problem that can interfered with rehabilitation as well as activities of daily living. Methods : Thirty subjects untrained were randomly assigned into Massage group, Taping group, Massage and Taping group. Treatment were applied at 24 hours, 48 hours and 72 hours after induction DOMS. The effects of Massage and Taping and Muscle strength and flexibility on DOMS were evaluated by a goniometer and dynamometer and taping and VAS sheet. Results : The results of this study were as follow : 1) There was a significant difference among Taping group, Massage group, Taping and massage group in the case of using graduator. The interaction of group shown a significance (p<.05). 2) In the case of using goniometer, all three groups had the significant difference in period (p<.05) and the interaction of group-period shown a significance(p<.05). 3) In the case of using VAS, all three group had the significant differences in period(p<.05) and the interaction of group-period shown a significance(p<.05). Conclusions : These findings suggested that Taping and Massage had effect on DOMS.

Several non-methylotrophic bacteria have been reported to improve the growth and activity of methanotrophs; however, their interactions remain to be elucidated. We investigated the interaction between Methylocystis sp. M6 and Microbacterium sp. NM2. A batch co-culture experiment showed that NM2 markedly increased the biomass and methane removal of M6. qPCR analysis revealed that NM2 enhanced both the growth and methane-monooxygenase gene expression of M6. A fed-batch experiment showed that co-culture was more efficient in removing methane than M6 alone (28.4 vs. $18.8{\mu}mol{\cdot}l^{-1}{\cdot}d^{-1}$), although the biomass levels were similar. A starvation experiment for 21 days showed that M6 population remained stable while NM2 population decreased by 66% in co-culture, but the results were opposite in pure cultures, indicating that M6 may cross-feed growth substrates from NM2. These results indicate that M6 apparently had no negative effect on NM2 when M6 actively proliferated with methane. Interestingly, a batch experiment involving a dialysis membrane indicates that physical proximity between NM2 and M6 is required for such biomass and methane removal enhancement. Collectively, the observed interaction is beneficial to the methanotroph but adversely affects the non-methylotroph; moreover, it requires physical proximity, suggesting a tight association between methanotrophs and non-methylotrophs in natural environments.

Purpose: The purpose of this study were to analyze fatigue patterns of the rectus femoris muscle by isometric contraction. Methods: Twenty healthy subjects(10 male, 10 female) participated in this study. Maximal voluntary isometric contraction(MVIC) was measured by the dynamometer. Muscle activity was recorded from the rectus femoris muscle. During the experiment, the subject was seated in the chair. The measured items, median frequency(MDF) and root mean square (RMS), were collected from the surface EMG. All data were analyzed using repeated measures ANOVA. Results: There was significant difference of MVIC between male and female. Endurance time was significant difference by the level of MVIC but no significant in the main effect(sex) and interaction effect. The MDF and fatigue index were significant differences in the interaction effect. The RMS was not significant difference in both of main and interaction effect. The muscle fatigue patterns of female was greater than male after 60% MVIC. Conclusion: This study showed that sex differences of muscle fatigue were started from 60% MVIC.

To transmit users' intentions that vary with each person, intuitive and hi-directional interactions between users and a computer are necessary. We considered these interactions by dividing them into two spaces, physical space and informational space. Informational space supports human thinking process by arranging and visualizing much information. Physical space reproduces the real world where various restrictions exist to virtual space. From the viewpoint of three aspects - contents model, kansei model and context model - we defined the style of the interaction between user and multimedia database. In this paper, for the purpose of examining the way to realize the interaction based on these models, we developed interior design coordination support system and garden coordination system, and then evaluated them.

Background: Whole body-electromyostimulation (WB-EMS) is widely used for the rehabilitation and recovery of patients with various neuromusculoskeletal disorders. Objects: To objectively measure changes in lower extremity and abdominal muscles after sit-to-stand dynamic movement training using WB-EMS. Methods: A total of 46 healthy adults (23 experimental and 23 control subjects) performed sit-to-stand exercise; the experimental group with WB-EMS, and the control group without WB-EMS. The muscle activity of the lower extremity, and the muscle thickness of the lower extremity and abdominal muscles were measured before and after the intervention. Results: In terms of electromyographic activity, there was a significant interaction effect for the rectus femoris (RF) muscle (F=30.212, p=.000). With regards to ultrasonographic imaging, the muscle thickness of the RF muscle had a significant interaction effect at the muscle contraction ratio (F=8.071, p=.007). The deep abdominal muscles, such as the transverse abdominal (TrA) and internal oblique (IO) muscles, also showed significant interaction effects at the muscle contraction ratio (F=5.474, p=.024, F=24.151, p=.000, respectively). Conclusion: These findings suggest that WB-EMS may help to improve the muscular activity of the RF muscle, and the muscle thickness of the RF muscle and deep muscles such as the TrA and IO muscles.

Purpose: Service quality plays an important role in the credibility of consumer behavior as it enhances brand loyality in hospitality business. The objective of this study is to determine the effects of service quality, positive emotion, brand affection, and brand loyalty in restaurant sector by applying the S-O-R model. The study also introduces a new integrated structural model that combines service quality's dimensions of physical quality, interaction quality, and outcome quality. Research design, data, and methodology: This study was analyzed in a quantitative way using the survey results of 395 customers who had experience of visiting restaurants. All constructs were measured with multiple items developed and validated in prior studies. In this study, SmartPLS 4.0 was used to evaluate the research model. The reliability, convergent validity, and discriminant validity of the measurement tool were verified. Result: Result was found that service quality(physical quality, interaction quality, outcome quality) had a positive effect on positive emotion and brand affection. Also both of positive emotion and brand affection had a positive effect on brand loyalty. This study contributes to the service quality literature and has practical managerial implications.

다양한 센서 네트워크와 유비쿼터스 기술이 제공되는 지능형 협업 환경은 사용자를 위해 확장된 인터랙션을 제공할 수 있다. 기존의 인터랙션이 사용자와 컴퓨터 머신과의 직접적인 인터랙션이 주를 이룬 반면 새로 확장된 인터랙션은 사용자와 공간과의 인터랙션을, 실질적으로 공간을 구성하는, 관리와 제어가 가능한 구성요소와의 인터랙션을 나타낸다. 본 논문은 이러한 공간 인터랙션을 효과적으로 제공할 수 있도록 하기 위해서 공간 오브젝트를 등록, 인식하고, 특히 사용자의 의도에 맞는 태스크를 지원하기 위해 과거의 인터랙션 정보를 이용한 템플릿 기반 맵핑 알고리즘을 설계한다. 제안된 알고리즘을 이용하는 경우, 공간 오브젝트가 증가함에 따라 템플릿을 검색하여 처리하는데 드는 시스템의 비용이 어느 정도 향상되는지 실험을 통해 분석하도록 하며, 진행되는 모든 공간 인터랙션을 시각적으로 보여주기 위한 그래픽 기반의 도시 방법을 소개하고 결론을 맺는다.
