  • The purpose of this study is to develop comfortable patient gown for spinal surgery patients. The results of the survey confirmed inconveniences and problems with the current gown, and a new gown style was recommended. The recommended changes addressed design, pattern, and materials. The final experimental design for the top of the new patient gown is a wrap style that moves the center opening of the gown to the side and enables patients to control the length of the sleeves by attaching two snaps. The cutting line is aligned with the back brace location, and the issue of repeated bunching of the gown material by the brace was solved by substituting 100% knitted structure fiber. The sleeve length can be adjusted with snaps on the sleeve cap and hem. When lifting up the gown for treatment on specific areas of the body, doctors open the edge of the right side of the gown in order to lift up the top. The bottom of the new patient gown was made from 100% cotton knitted structure fiber, and it enables patients to control the length of pants by attaching two snaps on the side. The results of an on-site dressing suitability evaluation and a flexibility evaluation with respect to dressing/undressing indicated that the new patient gown was much better received than the existing gowns (A and B). Our hypothesis regarding new patient gowns was supported in both the fit and design categories.

  • Micro hollow cathode discharges (MHCDs) are high-pressure, non-equilibrium discharges. Those MHCDs are useful to produce an excimer radiation. A major advantage of excimer sources is their high internal efficiency which may reach values up to 40% when operated under optimum conditions. To produce strong excimer radiation, the optimisation of the discharge conditions however needs a detailed knowledge of the properties of the discharge plasma itself. The electron density and temperature influence the excitation as well as plasma chemistry reactions and the gas temperature plays a major role as a significant energy loss process limiting efficiency of excimer radiation. Most of the recent spectroscopic investigations are focusing on the ultraviolet or vacuum ultraviolet range for direct detection of the excimer. In our experiments we have concentrated on investigating the micro hollow cathodes from the near UV to the near infrared (300~850 nm) to measure the basic plasma parameters using standard plasma diagnostic techniques such as stark broadening for electron density and the relative line intensity method for electron temperature. Finally, the neutral gas temperature was measured by means of the vibrational rotational structures of the second positive system of nitrogen.

  • The purpose of this study was to design an interactive multimedia nutrition education program for preschoolers. Computer technology provides the opportunity to explore new and creative methods of delivering nutrition education to pre-schoolers. If this method is effective, more preschoolers can be reached with accurate and consistent nutrition education with less time and teaching staff. This program is a computer-based multimedia nutrition education program for pre-schoolers based on the Dick and Carey (Dick & Carey 2001) model of instructional design which includes analysis, design, development, and evaluation. The overall instructional goal was based on the needs of the target population. The needs assessment was a self-administered survey distributed to 1,426 parents of preschoolers, focusing on the need for preschoolers' nutrition education. The results of the survey indicated that parents wanted their children to learn reasons for eating nutritious food. Therefore, a program titled 'Nutrition Exploration' was developed with the instructional goal of teaching preschoolers the 5 Food Groups. To achieve this goal, the preschoolers were engaged in a game. They could earn colored jewels by completing the game in five sessions. The story line was that people living in a peaceful kingdom become sick after they lose the jewels. The learner takes an adventurous journey through five different countries to retrieve the jewels. These countries are 'Giwoon nahrah' (foods containing carbohydrates, such as rice and potatoes), 'Sangsang nahrah' (foods that are rich in vitamins and minerals, such as vegetables and fruits), 'Sooksook nahrah' (calcium-con-taming products such as milk), 'Teunteun nahrah' (protein-containing foods such as meat and fish) , and 'Gakeum nahrah' (products with high sugar and fat content, such as instant foods and soda). The learner who obtains five jewels in five different countries can save the kingdom. For the program to be effective and efficient, the multimedia had to be easy for the preschooler to enter, use, and exit. The verbal instructions enhanced child autonomy, and the program was developmentally appropriate so that the young child could easily manipulate the software. This research provides the basis for the continued development of computer-based nutrition education materials.

  • 미국의 대표적인 초등학교 미술 교과서 중 하나인 Discover art에 나타난 조형 원리, 색채 및 분야별 디자인에 대한 분석이 다루어졌으며 아동의 발달 및 학습 단계에 딸 연속성을 가지며 각 학년 별로 단원을 구성하고 이를 교육하는가를 중심으로 검토가 이루어졌다. 특히 각 분야에서 새로운 단어 및 개념 소개, 다음 학년에서의 학습 반복, 색채의 수, 디자인 분야별 감상 및 실습을 통한 학습 등을 각 학년별로 조사하였다. 조형 원리는 단계적으로 잘 구성되어 있지만 선과 형태에 관한 부분이 너무 자세하고 반복적으로 전 학년에 학습되는 것으로 분석되었다. 전체적으로 타 분석에 비하여 디자인 교육 부분의 학습 비중이 적으며, 역사를 배우게 되는 5학년에 보조를 맞춘 디자인사의 소개가 이후 지속적인 학습이 이루어지지 않는 점은 개선이 필요한 것으로 분석되었다. 제품 디자인은 4학년 이전에서는 감상만을 위하여 소개되고 4학년에서 일회 실습이 있는 것에 불과하나 고학년에서의 반복 학습이 요망된다.

  • In the first half of 20th century, there was an abrupt change in society and social values. Therefore, a demand for functional women's sportswear started to increase. This paper has attempted to investigate the impact of functionalism on women's sportswear in the first half of the 20th century. The following results were obtained: First, anti-tradition was observed. There was a tendency to be separated from the past and against tradition. It was tried to pursue freedom, getting away from corset and petticoat. Second, structural functions were targeted. In other words, precise and efficient shapes and simple silhouette and line were emphasized. Third, fitness of purpose was found. More liberal and comfortable design has been targeted. That's why a variety of functional pants have been designed instead of skirts. Fourth, utility and practicality were found. Elastic fabrics such as wool and jersey and sweater have commonly used in sportswear. A variety of new fabrics have been used and details such as flare, slit and pleats have been designed. Lastly, non-ornamentality was found. The beauty of simple shape was pursued by omitting details or eliminating unnecessary ornaments. Monochrome and dark color were preferred and a use of accessories has declined. The result of this paper could be used in establishing a theoretical framework on the impact on social change, values and art and helpful In modern women's sportswear design and marketing which have become more important.

  • The purpose of this study was to improve the fitness of Korean manufactured apparel products being exported to China and to provide for the basic data useful to the development of a torso prototypes for the Chinese women. For this purpose, Chinese college women aged between 18 and 24 were sampled to test the fitness of the Korean manufactured apparels for the Chinese women sample and address the problems of unfitness and thereupon. The results of this study can be summarized as follows; As a result of testing the fitness of the Korean manufactured apparels for the Chinese women, it was found that Chinese women felt more or less comfortable for the front of the jackets, but felt less comfortable with their side and back. Such a finding suggests that the Chinese women's postures are more turned back than the Korean women's. And also for the slacks, lack of a crotch length causes unnecessary pulls and creases from the back part to the crotch of a pair of slacks and the side line was not suitably placed. For this reason, the differences between the body shapes of Chinese and Korean women should be thoroughly considered when drawing the patterns to export to China.

  • The purpose of this study is to establish a theory about the necessary structure for knitwear design, and to propose it with the practical data through the actual development of a high value added knit structure. For this study, the market was conducted along with literature reviews on the existing studies and the relevant books about knit structures. The market research aimed at the products released in the spring/summer and fall/winter seasons of 2012-2013, focusing on brand for middle aged women. The utilization of the structure by item and the characteristics of knit design were studied. The research was conducted on S/S products in May and July, and F/W products in October and December. As a result of the market research, it was shown that the lightweight structures with permeability such as plain, lace, links and links, this is repeated and rib structure were frequently utilized during the S/S season, while double structures with good shape stability were greatly utilized during the F/W season. Also, during the F/W season, a cable structure and tubular jacquard that emphasized the volume or cubic effect were frequently used, and there were many jacquard structures where a change of color sense and motive were added. Concerning the knit structures development, the researcher designed the knit structure at the actual production site of the knit fashion. A total of 5 pieces of knit structures were developed by asking a professional for programming and knitting. To the developed structures, the study added a multi-gauged effect, herringbone transformation effect, 3-dimensional surface effect, color effects, geometric patterns, lace penetration effect, and soft surface effect in a water-drop shape. In addition, the structures had differences in the added values by mixing various structures and diversely expressing color sense on the knitting line. This study proposes the direction for 21st century knitwear product design, through the development of a high value added knit structure.

  • 철도는 대중교통 수단으로 가장 일찍이 개발되어 근대 산업발전에 크게 기여하였으나 20세기 중반이후 자동차, 항공기 산업의 발달과 투자의 집중으로 철도시설의 낙후 등 정체화의 길을 걷게 되었다. 그러나 산업의 고도화 및 분업화로 인한 교통수요의 급속한 증가와 다양화로 대량수송, 고속성, 안전성, 정시성, 에너지 효율성 및 환경오염 방지 측면에서 탁월한 장점을 갖는 철도의 역할을 재인식하게 되었다. 최근 기존선의 개량 및 이설하고자 할 경우 기존선의 평면선형 제원은 기본적인 자료로서 필요하게 되는데, 만약 최초 선형자료의 기본인 설계도서가 분실되었거나 훼손되었을 경우에 설계제원의 복원이 불가능하며, 최근 발생되는 각종 재난으로 인한 선로 유실시 선형의 정밀 복구가 어려운 실정이다. 철도선형제원이 기본적인 지리정보 자료로서의 기능을 발휘하기 위해서는 누락된 기존선의 철도선형에 대한 제원을 알아야 한다. 따라서 본 연구에서는 사회간접자본시설인 철도를 대상으로 디지털 영상을 획득하고 분석 처리하여 선형의 3차원 형상을 재현하며, 선형제원을 역으로 산출함으로써 기존선의 선형자료를 정밀하게 추출하여 철도시설의 정보화 구축에 기여하고자 한다.

  • This study was conducted to investigate how child-care teachers participate, practice mealtime instruction, and perceive difficulties in food service, focusing on comparison between the teachers caring two different age groups: children younger than three years (Younger Group) and those three years or older (Older Group). Questionnaires were distributed to 151 child-care centers in Kwanak-gu, Seoul, Korea during December, 2011. Only the data from 25 child-care centers, where two respective teachers in charge of Younger Group and Older Group completed the questionnaires, were analyzed. The results showed that there was no difference in terms of child-care teachers' participation in food service practice between the two groups, except for serving method; 'Pre-plated' serving was used significantly more often in Younger Group, whereas 'Line-up' serving was used in Older Group. Approximately, three quarters of the child-care centers had policies or guidelines on mealtime instruction. During mealtime, child-care teachers tended to use frequently verbal instructions such as "sit up straight when you eat" about eating manner, "don't be picky with your food" about eating habit, and "wash your hands before eating" about eating procedure in both the groups. There was no statistically significant difference regarding child-care teachers' perceived difficulties in food service between the two groups. These results indicated that child-care teachers' participation and mealtime instruction in food service did not differ between the two age groups, although children's development of digestion and eating skill differed by age. Therefore, training should be provided to child-care teachers about food service practices and mealtime instruction appropriate to children's age.
