This thesis intends to suggest a new wedding dress pattern through researches on history and changes of wedding dress, researches on silhouette and details and analyses of existing basic patterns. In this study, to develop torso patterns of top dresses selected as preferred designs through literature reviews and company surveys, dress form sizes suitable for standard sizes were selected and study basic patterns were made using draping techniques. The study finds characteristics of body type dimension that is changed when wearing brassiere (hereinafter, 'bra') for wedding dress through customer surveys for development of basic patterns of wedding dress. That is, wearing wedding bra was used for the purpose of increasing the bust size and we will evaluate later whether this increase helps completeness of aesthetic impression through wearing evaluation. As the result, it was found out that top torso pattern wearing wedding bra made wearers feel more comfortable and in the aspect of aesthetic impression, it provided impacts on women's beautiful silhouettes. The effects of whether a bra is used or not on changes in patterns were reviewed through the degree of polymerization of finished patterns. When a bra for dresses was worn, the waist front length increased by1.7cm, the bust circumference increased by 2.1cm, and the amount of dart increased by 1.5cm in the patterns. A new torso pattern for top dresses, which will solve problems evaluated in each of the above from the aspect of composition of pattern by a method through analysis of existing basic patterns and multi-dimensional cut patterns wearing wedding bra, will be suggested.

Since Voyager 1 passed the Heliopause in 2012, it has provided the observations of the charged particles in the local interstellar medium. However, Voyager 1 only provides the information along with its trajectory. In order to understand the global view of the interstellar plasma flow surrounding the Heliopause, we need another tool. When the interstellar plasmas approach the Heliopause, the ions are deflected around the Heliopause due to the draping of the interstellar magnetic field. The draping of the interstellar magnetic field is strongly connected with the shape of the Heliopause. A fraction of the diverted ions exchanges their charges with the undisturbed primary interstellar neutral atoms, and then the ions become neutral atoms called the secondary interstellar neutral atoms. The newly created neutral atoms carry information on the diverted flow of the interstellar ions, and a fraction of them can travel to the Sun. Therefore, the secondary component of the interstellar neutrals is an excellent diagnostic tool to provide important information to constrain the shape of the Heliopause. The secondary interstellar neutrals are observed by Interstellar Boundary Explorer (IBEX) at Earth's orbit. Since 2009, two energetic neutral atom cameras on IBEX have measured neutral atoms and it has provided sky maps of neutral atoms. In this presentation, we will discuss the directional distribution of the secondary interstellar neutrals at Earth's orbit. In the sky maps, the primary interstellar neutral gas is seen between $200^{\circ}$ and $260^{\circ}$ in ecliptic longitude and the secondary components are seen in the longitude range of $160^{\circ}-200^{\circ}$. We also present a simplified model of the outer heliosheath to help interpret the observations of interstellar neutrals by the IBEX-Lo instruments. We extract information on the large-scale shape of the Heliopause by comparing the neutral flux measured at IBEX along four different look directions with simple models of deflected plasma flow around hypothetical obstacles of different aspect ratios to the flow. Our comparisons between the model results and the observations indicate that the Heliopause is very blunt in the vicinity of the Heliospheric nose, especially compared to a Rankine half-body or cometary shape.

The purpose of this study is to provide the basic knowledge for the pattern development of a flared skirt. Two flat pattern (FP) methods, the concentric circle method and the corrected concentric circle method, and a draping were used for pattern making. Using these patterns, skirts were made with lengthwise grain in the centerline. The influence of pattern making method on the silhouette of the flared skirt was evaluated by the hemlines formed at the skirt worn in a dress form. Moreover, the combined influence of pattern making method and cutting direction on the silhouette of the flared skirt was examined with the draping pattern (DP) skirt and a FP skirt with $45^{\circ}$ bias grain in the centerline. The DP skirt had more uniform nodes and formed a stable wave form than the FP skirts throughout the whole hemlines. The number of nodes was reduced with lining in the two FP skirts, whereas the number of nodes was not changed in the DP skirt. The unit wave form of all the skirts by three patterns showed long loop form, and the slope angles of the unit wave form of the two FP skirts were higher than that of the DP skirt. The silhouette of the flared skirt was highly influenced by the shape of the waist circumference line in patterns. The DP skirt with lengthwise grain in the centerline showed good silhouette with uniform nodes and high marking efficiency, compared to the FP skirt with $45^{\circ}$ bias grain in the centerline.

This study is based on the results of the $7^{th}$ Korea Human Size Survey (Size Korea). The standard body shapes of Korean women between 25 and 34 years old were analyzed and used to develop a prototype princess line for wedding dresses. or this purpose I conducted a literature review and a survey of the actual situation of domestic ligaments. In order to select suitable ligaments for the standard body type of 25~34 year-old Korean women, I collected the most representative ligaments from around the world: Stock man from France, Superior from the USA, KIIYA from Japan, and Pig and Nonno from Korea. They were then compared and analyzed. In the form of a formal wedding dress, a prototype princess line was developed by a draping technique in order to finely implement the human body fitting. To develop the prototype of the princess line, I made test garments with muslin. 25 to 34 years old Korean female standard body type Three human subjects close to the average measurement value were selected as subjects. An exterior appearance evaluation questionnaire was created with 28 questions focusing on the main parts of the prototype princess line. The clothes were evaluated three times. In this study, aesthetic and functional elements were considered for the development of princess line prototypes for wedding dresses. In addition, the amount of spare area was given differently. This study is significant in the achievement of a dress line closest that closely matches the human body line of the standard Korean female body type.

The research thesis has been intended to make a comparative analysis on the basic bodice pattern and basic skirt pattern changing on the basis of setting waist line of dress form in an effort to set reasonable standards in selecting the standard lines of drees form. The thesis has made the wearing evaluation by producing the sample of upper and lower dress based on A pattern and B pattern. In details, A pattern functions to keep waist line flatly down from lateral waist-right to posterior waist in a little curved state, paralleling bust line and hipline with waistline. And, B pattern functions to keep waistline, bust line and hipline horizontal paralleling with ground surface. SPSS win 10.1 program was used for the analysis of evaluation and t-test. The result is as follows: For basic bodice-front of upper dress, A and B patterns have made little significant difference. With regard to basic bodice-back, B pattern has got the higher evaluation than A pattern, in the pattern stability and appearance. For basic skirt pattern, A pattern has got the lower evaluation in the aspect of total back appearance, back dart, hip line, and waist line, and front drape. Basic bodice pattern of A pattern, which takes on the different horizontal standard lines of dress form depending on the selection of waistline, and basic skirt pattern has scored less in terms of pattern stability and appearance.
