The aim of this study was to analyze the design characteristics of Chinese fashion designer Feng Chen Wang and interpret their implicit meaning from a neo-deconstruction perspective. A review of domestic and foreign literature, outlined the develop- ment of deconstruction and neo-deconstruction, with neo-deconstruction's aesthetic features termed 'traditional fusion', 'positive playfulness', 'open communication', and 'multiple inclusiveness'. These features informed an analysis of Feng Chen Wang's fashion design. Four key findings emerged. First, 'traditional fusion' combines traditional Chinese colors, items, handicrafts, and patterns with modern design to break down boundaries between past and modern, tradition and fashion. Second, 'positive playfulness' promotes creativity and fun, using bright colors, exaggerated accessories, and playing withthe composition of traditional clothes to create a positive atmosphere. Third, 'open communication' emphasizes design that combines practicality and creati- vity in response to consumer needs, incorporating the thoughts arising from individual experiences and interest in social phenomena. Fourth, 'multiple inclusiveness' breaks down boundaries of sexuality, hierarchy, and body shape, embracing various ideas of beauty and respecting uniqueness through design that are seen as available to all. Using a neo-deconstruction perspective, Feng Chen Wang provides novel product planning ideas for Chinese fashion brands and reflects the values and meaning of modern design pursued by contemporary Chinese designers.

Ball-end milling process is widely used in the die and mold manufacturing because of suitable one for the machining of free-form surface. During the process, the pencil cutting operation can be adopted before finish cut to eliminate overload in uncut area caused by large diameter of ball-end mill. The ball-end mill cutter for the pencil cutting is easily deflected by cutting force due to the long and thin shape, and the tool deflection in pencil cutting is one of the main reason of the machining errors in a free-form surface. The purpose of this study is to find the characteristics of deflected cutter trajectory by constructing measurement system with eddy-current sensor. It was found that the severe reduction of corner radius produced the overcut during the plane cutting. Up cutting method induced the overcut both plane and slope cutting, but down cutting one induced the undercut. From the experiments, down cutting with upward cutting path can generate the small undercut surface.

Matemal behaviors of Korean mothers of one-year-old infants (26 boys and 21 girls) were observed at home. Mothers were from middle to upper-middle class families in Seoul. Trained observers visited the infant's home for 3 to 4 hours and observed infant-mother interactions in natural situation. After the home visit, observers sorted the Maternal Behavior Q-set into 9 piles, from most characteristics to least characteristics of the mothers. In general, Korean mothers were quite sensitive and responsive in their interactions with one-year-old babies. Mothers interpreted baby's cues correctly, noticed when baby was distressed, and slowed pace down to wait for baby's response. Maternal behaviors were somewhat different according to whether they interacted with boys or girls. Mothers of boys were observed to be less sensitive in their interactions than mothers of girls. Mothers of boys were more unaware of or insensitive to baby's signs of distress, their responses were more delayed, and provided baby to constant and unphased barrage of stimulation thus made baby overwhelmed. In contrast, mothers of girls enjoyed face-to-face interactions, slowed pace down, and their interactions revolved around baby's tempo and state.

본 연구에서는 저주파영역의 가진분무에 대하여 추가적인 내부가진을 수행함으로써 변조분사되는 분무특성에 대한 연구를 수행하였다. 회전식 가진장치를 사용하여 1차 가진을 생성한 후 2차 가진원인 마그네틱 밸브를 사용하여 변조하였다. 변조분무의 FFT결과와 분무패턴의 가시화를 통하여 관찰한 결과, 2차 가진 제어가 있는 변조분사의 경우 1차 가진만 있는 분사보다 분무의 상하 운동 진폭이 작으며 분무 하단류의 침투깊이가 증가하는 경향성이 발견되었다.

Recently, many researches on the system of superconducting power supply and superconducting magnetic energy storage (SMES) using high temperature superconducting (HTS) tapes has been progressed. Those kinds of superconducting devices use the heater trigger switches that have a control delay problem at moments of heating up and cooling down. One way to reduce the time delay is using a different HTS tape at trigger part. For example, HTS tape having lower critical temperature can reduce time delay of heating up and heating down stage for heater trigger operation. This paper deals with resistances joint with different kinds of HTS tapes which have different properties to verify usefulness of the suggested method. Three kinds of commercial HTS tapes with different specifications are selected as samples and two kinds of solders are used for comparison. Joint is performed with temperature and pressure controllable joint machine and the joint characteristics are analyzed under the repeatable conditions.

In order to fabricate the multilayer piezoelectric transformer by tape casting method, we investigated the effect of $TiO_2$ and PZT powder additions on the Ag/Pd electrode. Meanwhile, effects of $TiO_2$ and PZT powder additives on the microstructure and electrical properties of Ag/Pd electrode were investigated in detail. In addition, the multilayer piezoelectric transformers were fabricated and the characteristics with various load resistance were measured at resonance frequency. The voltage step-up ratio was continuously change with increasing input voltage and load resistance, and then output voltage and powers were increased with increasing input voltage at matching impedance. The temperature rise of multilayer piezoelectric transformers were increased with increasing input voltage and load resistance. Meanwhile, multilayer piezoelectric transformers sintered at $1100^{\circ}C$ show the favorable characteristics with a power of 15 W at $100\;{\Omega}$.

A single-gap and single-gamma transflective liquid-crystal (LC) display using patterned vertical alignment (PVA) mode was designed. In the device, a vertical electric field drives a vertically aligned LC to tilt down to optimize polarization efficiency. Electrodes of transmissive and reflective area were patterned $22.5^{\circ}$ and $45^{\circ}$ with respect to the polarizer so that a tilt-down direction of the LC director was $22.5^{\circ}$ and $45^{\circ}$ in the reflective and transmissive regions, respectively. In the device, the cell gap was the same for both regions, and the gamma curve matched each other in both regions because tilt angle of LC director was the same according to the applied voltage. Moreover, the dark state was irrespective of the cell retardation value at normal direction, which was highly important in massive fabrications. The switching principle and electro-optic characteristics of the device are reported herein.

The characteristics of ice packing factor (IPF) at the ice slurry system using one line type are compared with the system using two lines type. The installation space for one transporting line is saved at the one line system. For the one line type, the ice packing factor is reduced along the downstream, but for the two lines type, the ice packing factor is fixed. For the one line system, mass flow rate in the main line is fixed along the down-stream, but for two lines system, the mass flow rate in the main line is reduced along the downstream. For one line system, along the down stream after IPF=0, the temperature at the main steam is increased, and the extracted mass flow is increased. The initial IPF, at which the IPF is not arrived at zero upto the final node, is proposed for the B area.

This paper presents design and construct of flat type step-down piezoelectric transformer for the application to AC adaptor. This piezoelectric transformer operated in resonance vibration mode. In this paper, finite element method(FEM) was used for analysing piezoelectric transformers. Stress and electric field of the transformer were simulated at resonance frequency. Using this simulation results, we manufactured improved Rosen type piezoelecric transfomer and measured its output characteristics. As results, output power was linearly increased by increasing input power at resonance frequency and it was found that the transformer an invariable output power for input power. From these results, we expect that this piezoelecric transfomer can be applied to small size and low capacitive AC adaptor.
