  • 본 연구에서는 설계기준에 합당한 제약조건을 고려하여 최저경비의 관망시스템을 설계함을 목적으로 비선형계획법(NLP)을 적용하였다. 경기도 고양군의 고양배수지를 급수원으로 하는 배수유역에 실제 적용하여 기존의 설계와 비교한 결과 기존 수리모의모형에서 사용되고 있는 반복계산 과정이 필요없이 설계가 가능함을 알 수 있었고, 설계의 최적화를 도모하는 동시에 수요절점에서의 유량 및 수압조건을 만족시킬 수 있었다. 이상의 결과와 같이, 본 연구에서의 비선형계획법(NLP)을 이용한 상수도 관망설계가 실무에서도 효과적으로 사용될 수 있음을 알 수 있었고 최적화 설계로 인하여 경제적 측면까지도 고려할 수 있음을 알 수 있었다.

  • Recently, as the "Kidult" culture has become the culture of life, the vintage fashion doll market is rapidly emerging. This change, coupled with a tendency to cherish childhood memories among adults, shows a phenomenon that vintage dolls are gaining popularity. This study explored the possibility of creative fashion doll clothing design, aiming to satisfy consumers' more diverse and unique emotional needs and provide new perspectives and inspiration to the doll fashion industry and the fashion doll industry. Therefore, this study attempted to propose a fashion doll costume design using the Y2K fashion style that is currently popular. Based on publications and prior research considerations, the Y2K fashion style could be categorized into four main styles: 'Future Technology', 'The Matrix', 'Millennium Spice Girl', and 'Harajuku'. Based on characteristics of these four styles, this study designed and produced eight stylish doll costumes incorporating the Y2K style under themes of 'Ex Machina', 'Digital Warrior', 'Rebelious Sugar', and 'Harajuku Dopamine'. This can inspire fashion doll costume design and production based on trendy styles. This study can be a useful foundation for presenting more diverse directions for fashion doll costume design.

  • In this study, design characteristics of Village Parks in Seoul are investigated through an analysis of structuring themes expressed in spatial design. The goals and objectives of this study are: to emphasize the significance of design themes; and to demonstrate an approach to the design of landscapes through an analysis of structuring themes. For conducting this study, geometric forms and naturalistic forms were examined first. That is, the following 15 structuring themes were examined, as guiding themes: the 90$^{\circ}$rectangular theme; the 45$^{\circ}$/90$^{\circ}$angular theme; the 30$^{\circ}$/60$^{\circ}$ angular theme; circles on circle; concentric circles and radii; arcs and tangents; circle segments; the ellipse; the spiral; the meander; the free ellipse and scallops; the free spiral; the irregular polygon; the organic edge; and clustering and fragmentation. Forty five Village Parks in Seoul, built between 1996 and 1997, were analyzed through these 15 structuring themes. An analysis of Village Parks was conducted by the following two categories: land shape and structuring themes; and design directions and structuring themes. The research results are as follows; 1) Geometric forms are more frequently applied than naturalistic forms. 2) Regardless of land shape, geometric forms derived from simple primary shapes, the square and the circle, are frequently used. And the meander and the irregular polygon among naturalistic forms are frequently used. 3) Regarding design directions and structuring themes, design concepts, symbolic meanings and spatial forms are, to some degree, integrated. 4) The spiral is not applied among geometric forms. And the meander and the irregular polygon, as naturalistic forms, are frequently utilized. Research findings obtained from this study could be used in the designing of future Village Parks. For a profound study, future, research is needed in two-dimensional plans and three-dimensional elements of Village Parks.
