  • Objective: The purpose of this study was to identify kinematic variables that govern successful performance and judges' scores and to establish correlative relationships among those of Yurchenko layout with a full twist in female vaults. Method: Four video cameras with sampling rate of 60 Hz collected 32 motion data of Yurchenko vaults from twenty-two female participants (age: $18.6{\pm}3.6years$, height: $153.0{\pm}6.5cm$, mass: $44.7{\pm}7.3kg$) during national competition. Posting processing and calculations of kinematic variables were performed in Kwon 3D XP and $Matlab^{(R)}$ programs. Correlation and regression analyses were applied to find the relationships between the obtained scores and kinematic variables. Deterministic model (Hay & Reid, 1988) was used to investigate the strength of correlative relationships among kinematic variables. Results: The obtained scores from the judges' decision were mainly affected by post-flight peak height, horse contact time, knee angle at landing, and horse takeoff angle. Strong blocking during horse contact was required to get successful performance and obtain high scores. Modified deterministic model showed that round-off entrance and takeoff angles and resultant velocity of the center of mass (CM) during the roundoff phase were the starting variables affecting performance in the following kinematics. Knee angle at landing, a highly influential variable on the obtained point, was only determined by judges' decision without significant correlative relationship with previous kinematic variables. Conclusion: The obtained scores highly depended on kinematic variables of post-flight and horse contact phases that were affected by those from the previous phases including round-off postures and resultant velocity of the body center of mass.

  • The purposes of this study were to measure the degree of perceived uncertainty and to identify the rearing attitudes of mothers with chronically ill children, and to examine the relationship between the perceived uncertainty and the rearing attitude of these mothers. The subjects of this study consisted of 133 mothers with chronically ill children, registered at 2 university hospitals in Seoul. Data was collected from April 1 to May 31, 1996. The Parents' Perception of Uncertainty Scale(28-item 4 point scale) and the Maternal Behavior Research Instrument (49-item 5 point scale) were used. Data was analyzed by Cluster analysis, ANOVA MANOVA and t-test. Results of this study are summarized as follows : 1. Mothers perceived their uncertainty to be slightly high (Mn 2.48). The degree of perceived uncertainty by the four components slightly differed unpredictability(2.72), lack in clarity(2.58), vagueness (2.52) and lack of information(2.04) . The degree of perceived uncertainty of mothers with ill children revealed to be influenced significantly by the age of the ill children, duration of illness after the diagnosis, and the experience of hospitalization. 2. Among the rearing attitudes : moderatlely high affective(Mn 3.98) and resrictive(Mn 3.58) attitudes of mothers toward their ill children were identified. Mothers tend to give positive evaluations of their childrens' behaviors (Mn 3.38) and less rejection(Mn 2.81). 3. Mothers' rearing attitude were correlated with the degree of perceived uncertainty in illness ; mothers in the Low Perceived Uncertainty Group (Mn 1.99) revealed the highest affective (Mn 4.08), the lowest resrictive(Mn. 2.72) attitudes and tendency to give positive evaluations of their childrens' behaviors (Mn 3.54) compared to the High Perceived Uncertainty Group(Mn 3.26) and Moderate Perceived Uncertaity Group(Mn 2.57). 4. The degree of perceived uncertainty, the duration of illness after the diagnosis and the experience of hospitalization revealed to be significantly influential to the rearing attitude of mothers with chronically ill children. From the above results, it can be concluded that predicting and controlling mothers' uncertainty are necessary for improved, efficient nursing interventions and normal growth & development of the chronically ill children.

  • Since the late 19 century, the Choseon dynasty forcibly opened the door to western countries, including Japan. In addition, cultural propagation called 'modernity' caused subtle changes in dietary life. Based on the theory of colonial dual society, this study examined the dietary modernity in Kyungsung (mid 1930s~early 1940s) when 50 years had passed since the Open-Door policy. Three films, (1934), (1936) and (1941) (those made in 1930s~1940s) were analyzed. Twenty six scenes [14 scenes from , five scenes from , and seven scenes from ] related to the dietary life from films were chosen and classified according three criteria (degree of modernization, main influential countries, and benefit groups from modernization). The degree of modernization of all films was more than 80%. The average proportion of the countries that affected modernization were western (35%), western-Japan (28%) and Japan (20%). Approximately 33, 53 and 14% of the upper, middle, lower classes, respectively, benefited from diet modernization. The main places where modernized dietary culture could be enjoyed were cafes, western restaurants, tea rooms, and hotels. The main food or beverages that were considered as modernized dietary culture were liquor (especially beer), coffee, and western meals. People in Kyungsung in the mid 1930s~early 1940s experienced modernity in dietary life differently according to the social classes and these culture changes were generally accepted as a symbol of modernity.

  • The change and development of costume are related to the cultural and socioeconomic factors. In the 18th century the mode of the women's costume in France was greatly influenced by the Rococo style. Elegance and exaggerated ornaments were the major characteristics of the woman's cos-tume in the Rococo period. The high hairdress and the widely hooped panier represented the typical Rococo fashion. From the second half of the 18th century onwards the aristocracy began to lose the battle with the bourgeoisie for political and economic power, and at the same time bourgeoisie fashion exerted an influence on court dress. The court fashion dominated the women's dress fashion in France up to the Revolution. Marie Antoinette, The Queen of Louis XVI, was one of the most influential fashion leaders in the lath century. The fashion, after attaining its highest point in 1770s, changed to a new direction in 1780s under Louis XVI. From that period onward the dimensions were smaller, hairdresses were not so high, and the trimming on the various garments was less liberal. In the mode, exaggeration was replaced by simplicity, and formality was replaced by functionalism.

  • This study focused on the beoseon, traditional Korean socks that are a fashion item showcasing the beauty of the round hanbok shape. The study utilized the beoseon as an influential design motif and suggested 24 cultural fashion items to which the beoseon can be applied, including neckties, scarves, and T-shirts. For the purposes of this study, Adobe Illustrator CS3 and Adobe Photoshop CS3 were used for the motif design as well as the literature review on traditional beoseon socks. For the basic design motif, two basic forms were taken from the collection of the National Folk Museum of Korea. The key point of the motif development is that it maintains the basic shape of the beoseon but highlights the attractiveness of the Korean image by using repetition, rotation, symmetry and overlap into a new image pattern so that modern and chic images were taken into consideration for each cultural product. For the necktie, the mixed or repeated patterns for each motif were used as is. Alternatively, an oblique line pattern was adopted to express a stable and stylish image. For the T-shirt, a round-neck sleeveless type was designed. T-shirts were unified in the white color to highlight the image from the pattern. For the scarf, two shapes were displayed, square and rectangle. Through mixture of two repeated variation unit patterns for each motif, a splendid and stylish image was revealed along with various layouts.

  • Purpose: The aim of this study was to identify perception, use status and factors influencing use of medical alert identification (ID) in diabetic patients who are on insulin. Methods: A survey was conducted from December 2013 to April 2014 with 198 people who were asked to participate in the survey. Results: The medical alert ID perception score was 3.54 on a 5-point scale. Most of respondents (82.8%) knew about the medical alert ID, but only 23.2% of respondents wore a medical alert ID and only 43.5% of respondents always wore a medical alert ID. Perception and frequency of possession were positively correlated (r=.41, p<.001). The most influential factor for the possession of a medical alert ID was the perception of the medical alert ID (${\beta}=.41$, p<.001). The perception of the medical alert ID explained 17% of variance in possession of a medical alert ID. Conclusion: Most of diabetic patients who take insulin received education about hypoglycemia and knew about the medical alert ID, but only few of them wore a medical alert ID. Findings from this study indicate that perception is an important variable related to possession of a medical alert ID in this population.

  • Single point diamond turning technique for optical crystals is studied in this paper. The main factors which are influential the machined surface quality are discovered and regularities of machining process are drawn. Optical crystals have found more and more important applications in the field of modern optics. Optical crystals are mostly brittle materials of poor machinability. The traditional machining method is polishing which has many shortcomings such as low production efficiency, poor ability to be automatically controlled and edge effect of the workpiece. The purpose of our research is to find the optimal machining conditions for ductile cutting of optical crystals and to apply the SPDT technique to the manufacturing of ultra precision optical components of brittle material(Ge). Many technical challenges are being tried for the large space infrared telescope, which is one of the major objectives of the National Strategic Technology Road Map (NSTRM).
