  • Recently, UAV(unmanned aerial vehicle) has evolved into various figure and become miniaturized. On using existing design method, it is hard to make modelling and standardizing design of flight control system of the figure including cylinder like pipe. These problems are caused by uncorrect express of nonlinearity in controller design. Therefore, it is developed through step of correct modelling and simulation on real time sing high efficiency computer in aircraft development of various figure. This is reducing period and expense of aircraft development. For the shake of solving these problems, in-design method has been devised by H.M. Wang. In this paper, an object of control is cylindrical UAV instead of the general figure of aircraft. It was analyzed flight condition, specification about level flight of the UAV and was presented algorithm to find control value.

  • The purpose of this study is to analyze the image evaluation and the preference of tailored jacket focused on the collar's figure according to the body type and the degree of satisfaction with their body of middle-aged women. For this study, twenty seven different types of tailored jacket were designed with some variation of their silhouette, the length and the collar's figure on three hundred and twenty three middle-aged women ranging from 35 to 50 years old. There was a significant difference in the image evaluation and the preference of tailored jacket according to the body type of middleaged women. The women of the type 1 evaluated that portrait lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 2 evaluated that breast lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 3 evaluated that breast lapel collar were the most fascinating, elegant and active, tender and they preferred that style. The women of the type 4 evaluated that waist lapel collar were the most fascinating, elegant and active, tender and they preferred that style. There was a meaningful difference in the image evaluation and the preference of tailored jacket according to the degree of satisfaction with their bodies. As satisfied with their face size, they thought breast/portrait lapel collar were more attractive, graceful and active, soft and they preferred that style. As satisfied with weight they regarded portrait lapel collar as more attrative, graceful and active, soft and they preferred that style. In this study we found that the middle-aged women evaluated the tailored jacket which was looking esthetic and fitting their body types, as the most attrative, elegant, active, and tender clothing and they prefered that kind of tailored jacket.

  • Background Proximal interphalangeal joint (PIPJ) dislocations represent a significant proportion of hand clinic visits and typically require frequent follow-ups for clinical assessment, orthotic adjustments, and physiotherapy. There are a large number of treatment options available for PIPJ dislocations, yet no prospective or controlled studies have been carried out, largely due to the diversity of the various types of injuries. Methods We retrospectively reviewed all the PIPJ dislocations in our institution over a five-year period and directly compared the different splinting techniques that we have used over this time frame. Results There were a total of 77 dislocations of the PIPJ (57 men and 20 women) that were included in our study. We found that our management has shifted gradually from complete immobilisation to controlled early mobilisation with figure-of-eight splints. Following treatment, the range of motion of the PIPJ in the figure-of-eight group was significantly greater than that in the other three methods (P<0.05) used. There were significantly fewer hospital visits in the figure-of-eight splint group than in the other treatment groups. Conclusions The treatment of PIPJ dislocations has undergone a significant evolution in our experience. Early controlled mobilisation has become increasingly important, and therefore, splints have had to be adapted to allow for this. The figure-of-eight splint has yielded excellent results in our experience. It should be considered for all PIPJ dislocations, but careful patient selection is required to achieve optimum results.

  • The purpose of this thesis is to explore a common characteristic of the diverse oriental images mainly from the figurative point of view, and apply it to the contemporary expressions and methods of painting. To do that, I separated the concept of figure into two factors - form and image - and then approached and solved the problems of figure by explaining the two factors respectively. Separating form from image is neither to set two factors against each other nor to isolate any of those values. It is worth dividing the form and the image not only because the image of the oriental painting has a figurative value constituted from an external frame of the form, but also because it has a close connection with the meaning that the form holds inside. These are the reasons why I conceptualize the individual language of form and image. Furthermore, I attempted to investigate how those two factors and mutual relations between them make real figurative images under the principle of harmony and coexistence. The theme of this thesis - the figurative aesthetics and its contemporaneity in the oriental paintings is analyzed based on the understanding of 'figure' within the framework of oriental paintings. A research of image from the figurative point of view is valuable in that it criticizes the past method of thinking, and proposes an alternative formula for new way of thinking. In this regard, I indicated the limit of the theory of form-and-spirit that has been one of the most important conceptual theories . Instead, I' accessed to various aesthetic concepts - that are created in the course of image formulation - from the actual figurative point of view, and then even interpreted it as a figurative value of the oriental paintings and it's application within the specific and practical scope. During the course of research, I explored the conceptual elements of the tradition and the principle of figuration. I expect this study to make a footstone for bringing traditional aesthetics to the contemporary context of oriental painting.

  • Purpose : The purpose of this study was to establish intra-rater, inter-rater, test-retest reliability, and concurrent validity of figure-of-8 walk test in people with stroke. Methods : The subjects of this study were 17 patients who were diagnosed with a stroke. Subjects were tested twice by the same raters, with 1 day between tests. Subjects were assessed by two physical therapists. Test-retest reliability was calculated using intraclass correlation coefficients (ICC). The concurrent validity was demonstrated by spearman correlation of F8WT with 10m walking test (10MWT), timed up and go test (TUG), Berg balance scale (BBS), dynamic gait index (DGI) and four square step test (FSST). Results : Intra-rater, inter-rater, test- retest of F8WT time, showed high reliability. Intra-rater, inter-rater, test-retest of F8WT steps demonstrated high reliability. Intra-rater, inter-rater, test-retest of F8WT total smoothness score showed below moderate reliability. There was a significant positive correlation of F8WT time with 10MWT, TUG, FSST. There was a significant negative correlation of F8WT time with DGI, BBS. There was a significant positive correlation of F8WT steps with 10MWT, TUG, FSST. There was a significant negative correlation of F8WT steps with DGI. There was a significant positive correlation of F8WT test total smoothness score with BBS. Conclusion : The time, and number of steps in F8WT show high inter, intra-rater, test-retest reliability. The F8WT smoothness shows below moderate reliability. The F8WT shows high concurrent validity with other comparable balance, and walking tests. The F8WT is a valid and reliable measure for assessing walking function in patients with a stroke.

  • The purpose of this study was to examine the image perceived by fathers of children with Internet addiction. To achieve the study purpose, we conducted depth interviews with ten fathers of children with Internet addiction who had been diagnosed as At-Risk through a face to face meeting. The reason for choosing face to face interviews was to listen to the subjective stories and descriptions from fathers about the kind of fathers they are, which are felt and experienced in real life. More specifically, we selected the depth-interview methods through structured questions and non-structured questions. The interviews were held for two or three hours through an individual meeting of ten fathers and data were collected in order to conduct a categorical analysis. The figures discovered from fathers of children were divided into four categories; the father figure who is indifferent to the Internet use of his child, the father figure depending only on education through the Internet, the father figure who is in a weaker point than the Internet and the father figure who is addicted to the Internet. Based on the study results, we suggested the desirable behaviors, which may be useful for both fathers and children with Internet addiction as well as a follow-up study.

  • For establishing a standard of design element of the smart highway, this study investigated driver's anxiety EEG according to running speeds and geometric designs. Also, the experiment was implemented on 60 subjects. Based on running speed data and brainwave data, which were obtained from the experiment, this study analyzes anxiety EEG according to running speeds and geometric designs, and finally draws a forecasting model of anxiety EEG by selecting affecting factors of anxiety EEG. Forecasting model shows that left curve is the most influential on anxiety EEG figure. The reason is because when driver is driving on the first-lane, his or her visibility is impeded by a median strip. For this reason, anxiety EEG figure increases. And also steep downward slope and large radius of curve are heavily influential on driver's anxiety EEG figure. It is judged that anxiety EEG figure is increased by high speed on those section. Thus, the forecasting model of anxiety EEG suggested on this study will be utilized for design phase, and will decide the design speed on the superhighway. So, it will be used to make practical and safety road.

  • This study was conducted to compare the body image perception, weight control experiences and the eating disorders according to where they were born, and the length of residence in USA among Korean-American college students. Three hundred college students participated in the study: 144 males and 156 females, 122 America-born (AB) and 171 Korea-born (KB) who live in New York City and New Jersey. Subjects responded to a self-administered questionnaire. The results showed that the ratio of overweight (23.2%) and obesity (26.8%) of males was higher than females'(16.1% and 6.3%, respectively). There were no significant differences according to born-place or the length of residence in USA of KB. People who had tried to control their weight were 58%. The ratio of weight control experiences of females (72.4%) was higher than males' (42.4%) as well as people who were normal or underweight than who were overweight or obesity. There were no significant differences according to born-place or the length of the residence in the USA of KB. In body image perception, the subjects who were normal and underweight overestimated their body figure, and the subjects who were overweight and obese underestimated their body figure. The desired and ideal figure of female students was significantly thinner than the current figure and also that of male students. There were no significant differences according to born-place or the length of the residence in USA of KB. The ratio of eating disorder was 8.7%, and females had higher percentage than males. And shorter they lived in USA, the percentage of eating disorder was higher.
