Stamps for microcontact processing are fabricated by casting elastomer such as PDMS on a master with a negative of the desired pattern. After curing, the PDMS stamp is peeled away from the master and exposed to a solution of ink and then dried. Transfer of the ink from the PDMS stamp to the substrate occurs during a brief contact between stamp and substrate. Generally, negative-tone masters, which are used for making positive-tone PDMS stamps, are fabricated by using photolithographic technique. The shortcomings of photolithography are a relative high-cost process and require extensive processing time and heavy capital investment to build and maintain the fabrication facilities. The goal of this study is to fabricate a negative-tone master by using Nano-indenter based patterning technique. Various sizes of V-grooves and U-groove were fabricated by using the combination of nanoscratch and HF isotropic etching technique. An achieved negative-tone structure was used as a master in the PDMS replica molding process to fabricate a positive-tone PDMS stamp.

The purpose of this study is to characterize the intonational realizations of vocatives in comparison with those of appositives in English statements and questions, and to compare the realizations produced by English native speakers with those of Korean students. Unlike Pierrehumbert(1980), in which the tag expressions do not have pitch accents, Beckman & Pierrehumbert(1986) proposed that the vocatives have a special status in tonal alignment and duration and that they form an independent phrase with pitch accent. Our results reinforce Beckman & Pierrehumbert(1986): both English native speakers and Korean students realize the vocatives in terms of rising tone, and the appositives in terms of both falling tone in statements and rising tone in questions. Moreover, they pronounced the nouns before vocatives longer than those before appositives. However, native speakers impose the low phrase tone before vocatives in statements and the high tone in questions; whereas, Korean students either put the low phrase tone on pitch contours of both statements and questions, or tend to pause before vocatives, thereby constituting an intonational phrase.

This study compares and analyzes the designs of Burberry creative directors, Christopher Bailey and Riccardo Tisci. For this purpose, 322 photographs (176 Christopher Bailey and 146 Riccardo Tisci) were collected and the data analysis criteria were classified into color, shape, material, decoration, item, and fashion style. With respect to the data analysis method, statistical analysis and content analysis were combined. First, the design characteristics of Christopher Bailey top and bottom combined bright tone, tone-in-tone color scheme, H-line, heterogeneous material combination, and smart casual appeared very frequently. Second, the design characteristics of Riccardo Tisci top and bottom combined were monotone, tone-on-tone color scheme, H-line, heterogeneous material combinations, and street culture. Third, the design differences between creative directors were significantly different in color, tone, color arrangement, pattern, material type, material combination, detail, top and bottom items, and fashion style. Burberry men's wear maintains Burberry's traditional design identity with achromatic colors, beige-based colors, and beige checks. Christopher Bailey's design direction is characterized by modernity in a casual mood that emphasizes practicality. The design direction of Riccardo Tisci is characterized by a wide gap between images in a semi-formal style that emphasizes Burberry's tradition and a free-spirited casual style.

PURPOSE: This study examined whether ankle joint stabilizing taping and muscle control taping influenced the ankle range of motion (ROM), muscle tone, and balance ability in chronic stroke patients. METHODS: Ten stroke patients were assigned randomly to experimental group 1 (joint stabilization taping n = 5) and experimental group 2 (Muscle control taping n = 5). After general physical therapy in both groups, ankle stabilization taping was applied to experimental group 1, and muscle control taping was applied to experimental group 2 three times a week for a total of six weeks (18 times). RESULTS: The muscle tone and stiffness of the gastrocnemius (GCM) showed significant differences between the experimental 1 and experimental 2 groups (p < .05). The Berg Balance Scale (BBS) and ROM also showed significant differences within the experimental 1 and experimental 2 groups (p < .05). The BBS and ROM also showed no significant differences between the experimental 1 and experimental 2 groups (p > .05). CONCLUSION: This study examined the muscle tone, balance, and ROM on the paraplegic side of stroke patients using kinesio taping, and the effect of the taping application method was confirmed from the preceding study. Therefore, it can decrease the paralysis side muscle tone and improve the ROM and balance ability.

PURPOSE: This study examined which stretching exercise had the most positive effect on increasing the range of motion (ROM) of the knee joint in healthy people and whether there was a difference between continuous stretching and intermittent stretching. METHODS: This study included 30 healthy university students from OOO University. The subjects were asked to sit on a mat and perform hamstring-stretching exercise during which the ROM and muscle tone were measured with pre and post-tests. Each subject was assigned randomly to a continuous stretching group (stretching without relaxation time group, n=10, G1) or intermittent stretching group (stretching with 10s relaxing time group, n=10, G2; and stretching with 20s relaxing time group, n=10, G3). The participants conducted hamstring stretching exercises with a sit-and-reach box at three different rest times (0s, 10s, and 20s). Subsequently, they underwent passive knee extension (PKE) tests, in which the ROM of the knee joint was measured with a goniometer, and the muscle tone was evaluated using a MyotonPro. RESULTS: Significant differences in muscle tone, stiffness, and ROM were observed between pre-test and post-test in each groups (p<.05). Although the post hoc tests indicated no significant differences in muscle tone and ROM between the continuous stretching group and intermittent stretching group (p>.05), the rate of change of the ROM showed that the intermittent stretching group developed more effective maintenance of the hamstring flexibility. CONCLUSION: No significant differences in the muscle tone of the hamstring and ROM of the knee joint were observed according to the hamstring stretching exercises with three different rest times. On the other hand, the rate of change of the ROM showed that intermittent stretching maintained the hamstring flexibility more effectively.

The purpose of this study is to find out the various impressions that tone-on-tone coloration of shirts and ties gives. This experiment was based on the $2\times4\times4\times2$ factorial designs; colors (purple and green), shirt tones (vivid, light, dull, and dark), tie tones (vivid, light, dull, and dark) and perceivers' genders (male and female). The materials in the experiment developed for this study were composed of various stimuli and the response scales for each stimulus. The stimuli were 32 upper body photographs, which were color printed by CAD system (4D-box program). We unified those colors of shirts and ties, and then made shirt and tie tone different. 27 bi-polar adjectives, each of which was graded into seven in its degree, were used to evaluate the impression. The subjects of this research were 192 male and 192 female college students in Gyeongnam province including Jinju City. The data was analyzed by using SPSS program. Analyzing methods were one-way ANOVA and LSD test. The items of the adjectives were classified into 5 impression dimensions; potency, activeness, attractiveness, visibility and tenderness. In conclusion the impression through matching shirts and ties could be varied by the colors and the tones of shirts and ties. This study can be used as the basic color data in the males' clothes market which gradually pursuits high-quality, personality, and variety.

奚琴 音質의 音響學的 特性을 조사하기 위해 奚琴音의 파워스펙트럼과 時間波形을 FFT Analyzer를 이용하여 분석하였다. 奚琴絃의 張力과 遠山(bridge)의 위치, 腹板(top plate)의 두께등을 변화시키면서 분석을 하였다. 실험에 의하여 다음과 같은 결론을 얻었다. 腹板의 共振周波數가 絃의 基音의 周波數보다 높기 때문에, 基音의 音壓보다 腹板의 共振周波數 부근의 上音들의 音壓이 더 큼을 알았다. 絃의 張力이 강할 때와 遠山이 腹板의 중앙에 위치하였을 때가 音質이 보다 우수하였다. 奚琴 遊絃의 inharmonicity 계수는 0.049 cents/$n^2$이었다. 5kHz 이상의 上音은 발견할 수 없었으며, 奚琴의 inharmonicity가 violin의 inharmonicity보다 큰 값을 나타내었는데 이를 통해 奚琴음의 明瞭度와 豊富性이 부족하다는 것을 알 수 있었다. 奚琴筒의 共振周波數(MAR)와 腹板의 共振周波數(MWR)의 周波數比는 1 octave 정도일 때 奚琴이 가장 좋은 음색을 갖는다는 것을 밝혔으며 이때 腹板의 두께는 4.5mm 정도이다.
