The purpose of this study was to identify the constructive principle and techniques of Vionnet's works. According to analysis of Vionnets works, it was found that Vionnet conceived of the human body as a continuous shaping of a cylinder. Vionnet's drapery denied the planner presumption of woman and gave real three-dimension to form and to fashion. The techniques of Vionnet's works were as fallow : (1) She introduced the diogonal "bias cut" and changed dress design by her sensuous use of fabrics. (2) She eliminated interfacing to keep the silhouette and the fabric soft. (3) She manipulated the fabric to remove the excess for fit and decoration at the same time. (4) She treated the fabric with a synthesis of geometry and grace. (5) The sale luxury allowed was to note the choice of seams, facings, hems, and stitches. (6) Vionnet's dresses were not lined.

본 연구에서는 신체상 위협상황에서 대처 전략을 측정할 수 있는 한국판 신체상 대처전략 척도(K-BICSI: The Korean Version of the Body Image Coping Strategy: K-BICSI)를 사용하여 회피 전략을 사용하는 정도에 따라 고회피집단(N=12)과 저 회피집단(N=12)으로 구분하여 실험참가자를 모집하였다. 연구의 목적은 외모 관련 자극이 제시 되었을 때 달라지는 주의편향과 자극 제시 전후의 정서변화를 살펴보는 것이었다. 실험 참가자는 여대생 24명으로, 안구운동 추적장비의 최초 응시방향과 응시시간을 이용해 주의편향을 확인했으며, 정서변화는 VAS로 측정하였다. 분석 결과 고 회피집단은 저 회피집단에 비해 비매력자극에 대한 더 높은 최초응시 경향을 나타냈지만, 매력자극에 대해서는 유의미하게 긴 응시시간을 보였고, 외모관련 지극 제시 전보다 후에 더 유의미하게 정서가 부정적으로 변하였다. 본 연구의 결과로 고 회피집단은 저 회피집단과는 다른 주의 인지기제를 가지고 있으며 외모관련 자극에 정서적으로 민감하게 반응한다는 것을 확인할 수 있었다.

1T-DRAM cell with solid phase (SPC) crystallized poly-Si thin film transistor was fabricated and electrical characteristics were evaluated. The fabricated device showed kink effect by negative back bias. Kink current is due to the floating body effect and it can be used to memory operation. Current difference between "1" state and "0" state was defined and the memory properties can be improved by using gate induced drain leakage (GIDL) current.

Artifact corrections including normalization and attenuation correction were important for quantitative analysis in Nuclear Medicine Imaging. Normalization is the process of ensuring that all lines of response joining detectors in coincidence have the same effective sensitivity. Failure to account for variations in LOR sensitivity leads to bias and high-frequency artifacts in the reconstructed images. Attenuation correction is the process of the correction of attenuation phenomenon lies in the natural property that photons emitted by the radiopharmaceutical will interact with tissue and other materials as they pass through the body. In this paper, we will review the several approaches for normalization and attenuation correction strategies.

For its synergistic relationship, an integrated SDINS/GPS system has been adopted in many navigation areas. As an application of SDINS/GPS integration, the in-flight alignment process of a SDINS utilizing GPS carrier phase measurements is introduced and analyzed via an observability analysis using nul1 space method. A measurement model of double-differenced GPS carrier phase measurements is newly derived in order to be used with a SDINS error model. Also, conditions for determining the complete observability of a SDINS/GPS system are suggested and proved. Consequently, it is shown that the system is not completely observable in case of one basel me. With one baseline aligned with y-axis of body frame, pitch error and x-axis accelerometer bias are unobservable states. Also shown is that al1 states are completely observable when sequential maneuver is performed. Above results are confirmed by a covariance analysis.

In this paper, reorientation based on angular momentum exchange is applied for a bias momentum stabilized satellite, which is equipped with a spherical fuel tank, and the effect of liquid slosh on the attitude properties such as inertia tensor and angular rate is investigated. In order to represent the slosh motion of liquid an equivalent mechanical model is adopted and full nonlinear equations of motion for three-body system are derived. Computer simulations are performed for several cases, which use the viscosity of liquid and the center location of the tank as input parameters, mainly in order to observe how the viscosity of liquid and the center location of the tank influence the spacecraft’s attitude. The investigation includes observing time-variations of the inertia tensor, especially presence of components of product of inertia during the maneuver.

The purpose of this study is to discover the interrelationship between modern costumes and Seung-Hee Choi's dancing costumes in 1930s. Seung-Hee Choi, who was a dancing pioneer in Korea, introduced the modern dancing costumes for the first time in Korea. The results are as followed ; First, we can find Eroticism in Choi's dancing dress. Choi's dancing costume had used gold thread, silver thread, spangle, see-through and a half-naked body clothing that decorated with beads and cords. It is similar to modern costumes in ubjet mtter, silhouette, design, and so on. Second, the influence of Futurism was in her dancing costumes, that is, it represented asymmetry designs and rectilineal figures. Third, not only beauty but also a Functionalism was expressed in her dancing costumes. Functional beauty was shown through bias cut, pleats, slit, and so on.

In this work, the effects of corner transistors in SOI MOSFETs were investigated. We fabricated SOI MOSFETs with various widths and a fixed length and characterized them. The SOI thickness was $4000{\AA}$ and the buried oxide(BOX) thickness was $4000{\AA}$. The isolation of active region was simply done by silicon etching and TEOS sidewall formation. Several undesirable characteristics have been reported for LOCOS isolation in fabrication on SOI wafers so far. Although we used an STI-like process instead of LOCOS, there were still a couple of abnormal phenomena such as kinks and double humps in drain current. Above all, we investigated the location of the parasitic transistors and found that they were at the corners of the SOI in width direction by high-resolution SEM inspection. It turned out that their characteristics are strongly dependent on the channel width. We made a contact pad through which we can control the body potential and figured out the dependency of operation on the body potential. The double humps became more prominent as the body bias went more negative until the full depletion of the channel where the threshold voltage shift did not occur any more. Through these works, we could get insights on the process that can reduce the effects of corner transistors in SOI MOSFETs, and several possible solutions are suggested at the end.

Objectives: The purpose of this study was to determine whether gocho (苦椒) extract mesotherapy can effectively reduce weight and abdominal fat in obese patients. Methods: Forty obese participants were recruited and randomly assigned to two groups. Five participants dropped out voluntarily during the course of the study and four men were excluded from the analysis to avoid gender bias. Results are presented on a total of thirty-one women. Over an eight-week period, the treatment group (n=13) received gocho (苦椒) extract injections (100mcg/3cc) in the abdominal skin, twice per week; the control group (n=18) received normal saline injections (3cc). A mixed lidocaine and prilocaine cream (2.5%/2.5% EMLA cream) was applied before the injection. At baseline and 8 weeks, body weight, body-mass index (BMI), waist circumference (WC), waist-hip ratio (WHR), abdominal fat, energy expenditure, and questionnaires (eating attitudes and physical activity) were evaluated in both groups. Results: Reductions in body weight (p<0.005), BMI, and WC (p<0.05) were greater in the treatment group. WHR, total fat area, and visceral fat area decreased only in the treatment group (p<0.05). Resting metabolic rate (RMR) change was correlated with weight loss only in the control group (r=-0.498, p<0.05). Before and after the treatment, there were no significant differences between the two groups in questionnaire variables (p>0.05). Conclusion: his study suggests that abdominal gocho (苦椒) extract mesotherapy might be an effective way to promote weight and abdominal fat loss in obese Korean women.
