본 연구는 대전 스카이로드 미디어 파사드의 공공 디자인 평가와 감성 평가의 특성을 살펴보고자 하였다. 이를 위해, 대전 스카이로드 미디어 파사드 영상물을 시청하여 대상자들이 미디어 파사드의 공공 디자인 평가 항목과 감성 어휘로 구성된 감성 평가 항목에 응답하도록 하였다. 그리고 인구통계학적 변인에 따른 대전 스카이로드 미디어 파사드의 공공 디자인 평가 결과의 평균 비교를 진행하고, 감성 어휘의 요인 구조를 도출하여 각 요인에 포함되는 감성 어휘를 바탕으로 공공 디자인 평가 요인과의 상관분석을 진행하였다. 그 결과, 대상자들의 성별, 미디어 파사드 경험 여부, 연령에 따라 일부 차이 및 경향성을 보이는 공공 디자인 평가 항목이 존재하는 것으로 나타났다. 한편, 감성 어휘의 요인 구조로는 총 14개의 어휘가 4개의 요인 구조로 구성되었으며, 모든 공공 디자인 평가 요인에 걸쳐 공통으로 관련성이 높은 감성 어휘로는 “쾌적한-불쾌한”이 존재하는 것으로 나타났다. 이는 주관적으로 쾌적하다고 인식되는 감성이 공공 디자인으로서 대전 스카이로드 미디어 파사드의 주된 가치로 평가될 수 있음을 시사한다. 다만, 성별과 연령을 고려한 정책이 반영되어 대전 스카이로드가 운영된다면 공공 디자인으로서의 가치가 더 향상될 수 있을 것으로 기대된다.

Eutrophication and algal blooms can lead to increase of taste and odor compounds and health problems by cyanobacterial toxins. To cope with these eco-social issues, Ministry of Environment in Korea has been reinforcing the effluent standards of wastewater treatment facilities. As a result, various advanced phosphorus removal processes have been adopted in each wastewater treatment plant nation-widely. However, a lot of existing advanced wastewater treatment processes have been facing the problems of expensive cost in operation and excessive sludge production caused by high dosage of coagulant. In this study, the sedimentation and dissolved air flotation (SeDAF) process integrated with sedimentation and flotation has been developed for enhanced phosphorus removal in wastewater treatment facilities. Design and operating parameters of the SeDAF process with the capacity of 100 m3/d were determined, and a demonstration plant has been installed and operated at I wastewater treatment facility (located in Gyeonggi-do) for the verification of field applicability. Several empirical evaluations for the SeDAF process were performed at demonstration-plant scale, and the results showed clearly that T-P and turbidity values of treated water were to satisfy the highest effluent standards below 0.2 mg/L and 2.0 NTU stably for all of operation cases.

This study aims to derive the criteria of folding techniques and their characteristics through analysis of literature and previous studies. This will be realized by performing a case study on male fashion design and folding. It will propose diverse directions and data for male fashion design, by making men’s jackets using a folding technique. The concept and terms of folding were clarified through examination of existing literature and previous studies. Specifically, four pieces were created with motifs of the four seasons. Among the types of pleats expressed in the works, composition pleats include double ruffles, gathers, and draperies, while processed ones include box pleats, knife pleats, and accordion pleats. This study expresses continuity, fluidity, scalability, and ambiguity through the use of such pleats. The results of the production are as follows. First, in terms of the continuous use of regular and repetitive pleats, a possibility of rich pleats was confirmed because they varied depending on the gap between the pleat and target material. Second, in liquid but irregular pleats, diverse moods were created by the pleat movement. The overlapping of repeated pleats expresses diverse spaces and shapes in a 3D extended silhouette. Third, in pleat classification, ambiguity was confirmed with the use of continuous accordion pleats in the printed gradation fabric. It is anticipated that more diverse and creative designs could be created using more extended techniques in future studies.

The purpose of this study is to analyze the eco-friendly design characteristics of contemporary children’s collections. Photos from FirstviewKorea were utilized for analysis; 29 brands were selected that included children’s clothing collections featuring eco-friendly characteristics from 2007 to 2018. The results are as follows. First, naturalness was the most frequent characteristic of environmentally friendly children’s collections. It was not conveyed in an eccentric way in any season, showed a relatively uniform distribution, and was seen in various ways, including printed on the fabric and expressed in appliqués and embroidery. Second, handcrafted features frequently changed according to seasonal trends. Various methods such as beading, embroidery, applique, sewing techniques, and handbags were used, which enhanced manual workability, discrimination from other designs. Third, traditionality is divided into the characteristics of ethnicity and revivalism. National traditions were expressed in the clothing and reflected the current generation while connecting to the past. Fourth, simplicity appeared in classic designs such as simple silhouettes, sparse decoration, natural colors, and comfortable dress length that is not tight on the body. Simplicity was not a frequent feature due to the characteristics of the children’s clothing collections. Fifth, playfulness functioned to enhance the children’s clothing’s wear frequency. Although it was the least frequent of all the characteristics, it seemed to increase the design fun and the clothing’s value by fusing with other characteristics such as handcraftedness and naturalness.

The site coefficients in the common requirements for seismic design codes, which were promulgated in 2017, were reevaluated and the standard design spectrum for soil sites were newly proposed in order to ensure the consistency of the standard design spectra for rock and soil sites specified in the common requirements. Using the 55 ground motions from domestic and overseas intraplate earthquakes, which were used to derive the standard design spectrum for rock sites, as rock outcropping motions, site response analyses of Korean soil were performed and its ground-motion-amplification was characterized. Then, the site coefficients for soil sites were reevaluated. Compared with the existing site coefficients, the newly proposed short-period site coefficient Fa increased and the long-period site coefficient Fv decreased overall. A new standard design spectrum for soil sites was proposed using the reevaluated site coefficients. When compared with the existing design spectrum, it could be seen that the proposed site coefficients and the standard design spectrum for soil sites were reasonably derived. They reflected the short-period characteristics of earthquake and soil in Korea.

This research investigates and analyzes the distribution, creation period and creators, design characteristics, and process of change undergone by existing meandering streams used for the floating of wine cups(Liú shāng Qū shuǐ) in China. This study was conducted through literature review, fieldwork investigation and internet research. This research presented a categorization method and standard for discussion toward future research in this field by first categorizing Liú shāng Qū shuǐ facilities into five style categories: Lántíng style(A), Natural stream style(B), Cut stones excavation style(C), Broad natural rock carving style(D) and waterway style(E); this classification was carried out in addition to categorizing the Curved-stream banquet sites of B and C that are characterized by the stone carving style into the subcategories of Cut stones excavation and Broad natural rock carving styles. It is said that the ancient Liú shāng Qū shuǐ facilities of China are the product of natural landscape water systems and Pungryu(elegant lifestyle) culture; from the middle ages of the Tang and Song dynasties, garden forms changed to reflect miniascapes and an imitation of a landscape style, which represented a gradual transition from a tradition that entailed moderation in drinking and natural landscapes that copied Pungryu to those that were symbolic and placed more emphasis on games and amusement. Later in the modern Ming and Qing dynasties, the Cut stones excavation style became the mainstream approach for Curved-stream banquet sites. From this development, it seems that the Curved-stream banquet sites of China gradually evolved from Pungryu facilities used for water systems to garden facilities for amusement. However, the Lántíng⋅Natural stream⋅Cut stones excavation styles seem to have been continuously passed down in eclectic forms throughout all periods of Chinese history.

The purpose of this study is to collect and analyze costumes presented in international dance sports competitions, and summarize the features of Latin American dance costumes’ design. As for research methods, standards of Latin American dance costume design were analyzed via a literature review on dance sports. The scope of the study extended for six years from 2010 to 2015 to include the, top three UK Latin American dance competitions. The results are as follows. First, the silhouette analysis determined that the X silhouette to the lead with, −145 costumes (78%), followed by the H silhouette at 25 (13%), and other at 16 (9%). Amongst those there were 174 one-piece dresses (94%). Furthermore, the analysis on colors of Latin American dance sports costumes revealed that, amongst the 186 costumes, 115 were without color (62%), Bl(black) is the most frequent with 37%, then Wh(white) with 21% and Gr(gray) with 4%. Costumes with colors, based on the six basic colors in the Munsell color system, are comprised most often of red with 12%, the followed by Y(yellow) at 10%, B(blue) at 8%, YR(yellow-red) at 4%, P(purple) at 2%, and G(green) at 2%. Thirdly, the cloth materials of Latin American dance costumes are recognized through image inspection. Among visually recognizable materials, beading materials are the most common with 104 costumes (60%). Shiny materials like mesh, chiffon, organza, lace and burn-out are in 36 costumes in total (19%). Other cloth materials included Luster materials and; non-sheen materials, which were in 46 costumes (25%).

최근 총톤수 16만 톤급 이상의 대형 크루즈선이 국내 항에 정기입항하고 있다. 크루즈를 이용한 국내 관광객이 증가함에 따라 정부에서는 크루즈산업 활성화를 위해 항만기반시설 확충에 많은 노력을 하고 있다. 현재 국내 주요 항구에서 크루즈전용부두 공 사가 진행되고 있다. 그러나 국내 항만 및 어항설계기준에는 크루즈선 및 접안시설에 대한 표준제원이 제시되어있지 않다. 대상선박의 표준제원이 제시되어있지 않아 전용시설물 설계 및 인허가에 많은 어려움이 예상된다. 그래서 본 연구에서는 크루즈선에 대한 표준제 원을 제시하기 위하여 현재 운항중인 크루즈선의 톤수별 대표선형의 제원을 분석하고 PIANC 사례 및 국내 항설기준을 비교분석 하였 다. 분석결과 크루즈선은 연안여객선과 선박제원 및 선박조종성능에 차이가 있음을 알 수 있었다. 따라서 크루즈 전용시설물 설계를 위해서는 반드시 대상선박의 제원이 국내항설기준에 반드시 포함되어야 한다. 그리고 선박의 범위를 산정하기 위하여 크루즈선 평균 제원 값에 커버율(75%)을 적용하여 크루즈선 표준제원과 수역시설물에 대한 기준을 제시하였다.

As the international competitive landscape deepens, the need to understand foreign cultures and establish effective strategies is increasing. At the beginning of the 20th century, Cartier actively developed exotic designs to secure international competitiveness; theses designs have also been used as design prototypes for Cartier in modern times. The purpose of this study is to analyze the color characteristics and types of exotic designs in the early 20th century, which was a turning point in Cartier's design. After studying the literature, a total of 248 exotic designs were presented in Cartier catalogs. This study also selected overseas monographs from the early 20th century, and their design types were classified and color analysis was performed based on the Natural Color System(NCS). Cartier’s exotic designs cover wide range of styles, such as Chinese, Japanese, Persian, Indian and Egyptian styles. Multicolor, primary colors, and contrast are all strongly expressed. 97% of designs contained multiple colors, with at least two colors and maximum of six colors. The most frequently used colors are red, green, and blue, which means that only 9% of the designs do not contain the three colors, showing a high preference for theses three colors. In addition, color combinations of red and green, red and blue, or all three colors are used to show high contrast and utilize complementary colors, or near complementary colors, for coloration. This study is meaningful in that it analyzes the color characteristics of Cartier’s exotic designs and translates them into practical data for establishing the color strategies of companies in the global market.

The purpose of this study is to investigate the design methods and characteristics of papercraft fashion from 2001 to 2015. The study has been conducted through theoretical research and case study. Overall, types of papercraft expressions are classified into the following four categories: narrative papercraft fashion, organic papercraft fashion, variable papercraft fashion, and recycling papercraft fashion. The characteristics and aspects of each type of papercraft is described below. First, narrative papercraft fashion expresses as factual description of the natural environment. These works convey fantastic image by showing fairy tale animals or plants using paper folding or cutting. Second, organic papercraft fashion creates a futuristic shape by expressing organic parts in nature. Also, it often depicts future-oriented images by repeatedly representing organic shapes using uniform patterns in nature. Third, variable papercraft fashion expresses a variety of changing shapes through a flexible design based on the style of wearing. This variation may be accomplished through changeable dress connected to human gestures. Variable papercraft represents playfulness, which conveys enjoyment to the wearer and the audience. Fourth, recycling papercraft fashion uses paper materials of the past, and recreates them into artworks through handicraft techniques. Recycling papercraft conveys high value added fashion by dissolving the material into pulp.

According to the structure, solenoid valve can be categorized as spool valve or poppet valve. While various research on spool valve which has simple structure and fine susceptibility to contamination has been conducted, poppet valve which has less susceptibility to contamination and advantage in a long time operation still need much research because of its complicated structure. In order to design the poppet valve, various parameters such as the diameter of the poppet, the angle of the poppet, the diameter of the disk, the spring stiffness, the spring preload and flow path structure should be considered. Conventional studies on poppet valve usually take only one design parameters and did not much focused on the effect of the parameters on flow characteristics. In this paper, the change of the flow characteristics according to the design parameters of the poppet valve for 3/2Way solenoid valve is analyzed. The previous studies and the results of initial model analysis was referred for the selection of the design parameters. The effects of design parameters on maximum pressure, minimum pressure, and pressure drop was examined using analysis of means(ANOM).
