Objective: Joint mobilization for arthrokinematics altered by the positional fault of chronic ankle instability (CAI) is an effective intervention for stabilization. In this study, we compared the effects of ankle dorsi flexion range of motion (DFROM) and dynamic balance ability (DBA) in CAI patients via passive joint mobilization (PJM), a method traditionally performed in previous studies, and active joint mobilization (AJM), a method that can have a greater effect on cortical excitability with spontaneous movements. Design: Single-blind two-arm randomized controlled trial Methods: A total of 30 participants were registered: 15 each to the PJM and AJM groups. Each participant received a total of 10 intervention sessions, 10 minutes per session, 5 times a week for 2 weeks. PJM used Maitland's mobilization method to apply joint mobilization with talus in the posterior direction and AJM used an angular joint motion to induce patient's voluntary motion of medial malleolus anterior gliding and lateral malleolus posterior gliding, respectively. DFROM of the ankle was measured by using tape and DBA was evaluated by using the balance system. Results: Significant improvement was observed after intervention in both the PJM and AJM groups except for the DBA-anterior and DBA-right variables of the PJM group. There were statistically significant differences between the AJM and PJM groups in the DFROM, DBA-anterior, DBA-posterior, and DBA-right variables. Conclusions: The overall improvement of DFROM and DBA was found to be more effective in joint mobilization including voluntary movement. When it is accompanied by voluntary movement, it further affects the neuromuscular system of the ankle.

We fabricated piezoelectric unimorph cantilever generators (UCG) using $Pb(Zr_{0.54}Ti_{0.46})O_3$ + 0.2 wt% $Cr_2O_3$ + 1.0 wt% $Nb_2O_5$ (PZCN) piezoelectric thick films, which were produced by a tape casting method. The PZCN thick films were tailored with same width and thickness but different lengths from 7.7 to 57.7 mm in order to evaluate optimized UCG for energy harvesting device applications. When the length of PZCN film was increased, the resonance frequency of UCG was slightly increased from 7 Hz to 8 Hz, which could be due to enlarged area of the highly stiff piezo-ceramic film. However, the output power was proportionally increased with the length of PZCT film and it reached 4.68 mW (1.221 $mW/cm^3$) when the film's length was 57.7 mm under 25 g of tip mass at 8 Hz, which is sufficient for micro-scale device applications.

YBCO coated conductor is one of the most promising materials as a new generations wire especially for practical power applications. In this work, $YBa_2$$Cu_3$$O_{7}$ -$\delta$/(YBCO) coated conductors (CC) were deposited by pulsed laser deposition (PLD) from buffer layers to superconducting layer on hi-axially textured metal tape. The oxide multilayer buffered substrate of architectures of $CeO_2$/$YSZ/Y_2$$O_3$ was fabricated by PLD at steady status. Then YBCO layer was deposited on RABiTS substrate by stationary and reel-to-reel (R2R) continuous process and we compared with deposition conditions of both processes. The degree of texture of each layer was investigated using X-ray diffraction including $\theta$-2$\theta$ scans, $\omega$-scans and $\Phi$-scans analysis. Their surface morphology was observed by scanning electron microscopy (SEM). The FWHM of the X-ray $\Phi$-scans and $\Phi$-scans indicated that YBCO and buffer layers closely replicate the in-plane and out-of-plane texture of metal tape. Critical current (Ic) at 77 K, self-field of 75.8 A/cm-width, critical temperature (Tc) of 85 K, and critical current density (Ic) of 3.7 MA/$\textrm{cm}^2$ were measured from coated conductor deposited by stationary process. And coated conductor deposited by R2R continuous process had Ic of 57.5 A/cm-width, Tc of 86.5 K and Jc of 2.0 MA/$\textrm{cm}^2$. The film also exhibits a homogeneous and dense surface morphology.

얼굴과 하박내측의 피부는 경피수분손실량(TEWL), 피부 수분량, 탄력 등에서 많은 차이를 보이고 있다. 특히, 이전 연구 결과에서 얼굴피부와 하박내측 피부는 수화(hydrating) 과정에 따른 탄력특성의 차이를 보여 주었다. 이에 본 연구에서는 신체부위에 따른 피부특성 차이는 각 신체부위를 구성하고 있는 각질세포 특성과 연관성이 있을 것이라는 가정하에 atomic force microscopy (AFM)을 이용하여 각질세포 표면 특성을 비교 연구하였다. 각질세포 표면의 거칠기(roughness)와 villus-like projections (VPs)을 이용하여 비교 평가 하였다. 더 나아가 얼굴피부, 하박내측, 입술 피부의 각질세포 표면을 정성적으로 비교해 보았다. 각질세포는 8명의 피험자의 얼굴과 하박내측 피부에서 tape-stripping을 이용하여 채취하여, AFM을 이용하여 40 ㎛ × 40 ㎛ 크기로 각질세포의 아랫면 표면 특성(bottom surface of corneocyte)을 측정하였다. 그 결과, 얼굴 각질세포 아랫면 표면 거칠기는 388.34 ± 86.189 nm이었고, 하박내측 각질세포 아랫면 표면 거칠기는 662.27 ± 224.257 nm로 하박내측 각질세포가 얼굴 각질세포보다 더 거친 표면 특성임을 확인하였다(p < 0.001). 관찰된 VPs의 양을 비교해보면, 입술 각질세포가 가장 많았고, 그 다음이 얼굴 각질세포이며, 하박내측 각질세포는 낮은 수준이었다. 이러한 결과를 통해 볼때, 각질세포 표면 특성이 얼굴과 하박내측 피부 사이에 보이는 특성 차이에 어느 정도 관여하고 있음을 확인할 수 있었으며, VPs는 부위별 피부 특성 연구에 유용한 parameter가 될 수 있는 가능성도 확인할 수 있었다. 그리고, AFM은 각질세포 표면의 미세한 구조적 차이를 비교 연구하는데 매우 유용한 기기임을 알 수 있었다. 향후 조금 더 많은 연구가 진행된다면 각질세포에 대한 새로운 화장품 효능 평가법이 개발될 것으로 사료된다.

Piezoelectric thick films of a soft $Pb(Zr,Ti)O_3$ (PZT) based commercial material were produced by a conventional tape casting method. Thereafter, the interdigitated (IDT) Ag-Pd electrode pattern was printed on the $25{\mu}m$ thick piezoelectric film at room temperature. Co-firing of the 10-layer laminated piezoelectric thick films was conducted at $1,100^{\circ}C$ and $1,150^{\circ}C$ for 1 h, respectively. Piezoelectric cantilever energy harvesters were successfully fabricated using the IDT electrode pattern embedded piezoelectric laminates for 3-3 operation mode. Their energy harvesting characteristics were investigated with an excitation of 120 Hz and 1 g under various resistive loads (ranging from $10k{\Omega}$ to $200k{\Omega}$). A parabolic increase of voltage and a linear decrease of current were shown with an increase of resistive load for all the energy harvesters. In particular, a high output power of 3.64 mW at $100k{\Omega}$ was obtained from the energy harvester (sintered at $1,150^{\circ}C$).

선행연구에서는 위성체의 고기동 시 전개형 태양전지판으로부터 발생하는 잔여진동을 저감시키기 위해 초탄성 형상기억합금 (Shape Memory Alloy, SMA)을 적용한 적층형 태양전지판 요크를 제안하였다. 요크에는 SMA 양면에 구속층을 적층시키기 위해 점탄성 테이프가 적용되며, 점탄성 테이프는 온도 의존성이 높아 온도에 따라 댐핑 특성 변화로 요크의 진동저감 성능에 직접적인 영향을 미친다. 이에 따라, 온도별 요크의 댐핑 성능을 확인하기 위해 다양한 온도조건에서 자유감쇠시험을 수행하여 댐핑 성능이 가장 극대화되는 온도 구간을 식별하였다. 본 논문에서는 상기 온도시험 결과를 토대로, 요크가 궤도 열환경에 노출되더라도 효과적인 댐핑 성능을 유지할 수 있도록 궤도 열해석을 통해 요크의 열적 거동 및 온도를 예측하였으며, 요크가 최적의 진동저감 성능을 낼 수 있도록 열 설계안 도출 방안에 관해 기술하였다.
