This study was to develop the sunshade hat which reduced stress from solar radiation and ultraviolet radiation (UV), in order to keep the farmer's health and to promote their work efficiency. The new sunshade hat with a large brim, special structure for ventilation, stability and portability was designed and tested with manikin heads outdoors. Two newly designed sunshade hats(A, B) and three existing hat were tested Sunshade hat A made of double fabric with aluminum coating-nylon and black cotton cloth with a polyester mix(T/C) was the most protective from solar radiation. Sunshade hat B with larger brim was the most protective from ultraviolet radiation, even though it was made of aluminum coating-nylon single fabric.

도자기 보존담당자에 있어서 도자기의 전반적인 지식에 대한 이해는 그것들이 만들어진 방법이나 물리적인 특성이 손상과 밀접한 관련을 가지고 있으므로 필수적이라고 할 수 있다. 또한 도자기의 사용 중에 발생한 파손에 대처하는 여러 가지 수리복원 행위들 또한 반드시 규명되어야만 한다. 이렇게 파악된 지식은 도자기의 손상 원인을 파악하고, 적절한 보존처리방법의 선택에 매우 중요한 요소로 작용하며, 영구보존을 위해 매우 필요한 자료로 활용되기 때문이다. 이러한 수리복원 재료에 대한 규명의 일환으로 이번 연구에서는 도자기 구연에 부착된 금속 테두리의 제작목적과 제작시기, 사용된 재질의 성분 조사를 실시하였다. 연구대상 도자기 중 과학적인 분석이 가능한 금속 테두리에 대해서는 SEM-EDS 및 이동형 X-선 형광분석기를 사용하여 성분분석을 시행하였고, 반면에 분석이 어려운 도자기는 도록을 통한 육안조사로 재질의 성분을 추정하였다. 연구결과 다양한 재료를 사용하여 도자기 구연에 금속 테두리를 부착하였음을 확인할 수 있었다.

The objective of this study is to examine the type and characteristics of hat, and also to analyze the formative characteristics of hats shown in $Pr{\hat{e}}t-{\grave{a}}$-porter Collection. The literature review focused on the relevant technical books and preceding researches while the case study targeted 1,561 photos of hats shown in the 'Donga TV Collection'. The research range was from the S/S season of 2012 to the F/W season of 2015/16. The results of this study are as follows. 1. A hat is composed of crown and brim. In the results of classifying hats based on it, there were 572 crown-type hats, 533 hat-type, 219 cap-type, 156 irregular-type, and 81 brim-type in the order. 2. For the crown-type hats, they were mainly like cylindrical-type, bell-type, dome-type, and circle-type, using colors like black, beige, brown, red, mustard, and grey, and materials like wool, fur, velvet, straw, and metal while they were decorated with bead or lace. 3. For the hat-type hats, they were mainly like bell-type, ladder-type, and hemisphere-type, using colors like peach, white, gold, brown, and khaki, and materials like silk, cotton, straw, and wool while they were decorated with feather and ribbon. 4. For the cap-type hats, they were mainly like hemisphere-type, using colors like white, black, khaki, mustard, and purple, and materials like fur, leather, and wool while they were decorated with wappen and chain. 5. For the irregular-type hats, they were mainly like sandglass-type, box-type, animal-type, trumpet-type, and bell-type, using colors like purple, orange, pink, yellow, and sky-blue, and materials like metal, feather, mesh, plastic, straw, and linen while they were decorated with ribbon, net, bell, and flower. 6. For the brim-type visor, they were mainly like square-type, using colors like transparent, yellow, and black, and materials like plastic, cotton, leather, and metal.

The purpose of this study was to investigate the UVA radiation protection effects of summer hats currently on the market with the purpose of making it possible to choose a hat with suitable UVA protection. Twelve different summer hats from the market were selected for the experiment. The results are summarized as follows: It is more effective to wear a hat than not wear a hat to block UVA radiation. Summer hats with the greatest degree of protection, from highest to lowest, are cotton, straw2, and straw1. In the area of the forehead, which is rarely influenced by the irradiation angle, the cotton hat was the most effective in protecting from UVA radiation because the material density was greater than that of the straw hats. A hat with a 8.5 cm brim was more effective at blocking UVA radiation on the jaw than 6 cm, 4 cm, and 0 cm wide brims, but it still couldn't block the radiation completely. Irradiation amounts at 11:00 AM on the forehead, jaw! s and left and right cheeks were lower than amounts measured on the back of the neck. This revealed that irradiation amounts depend on the shape of the hat and time of day. A hat with a brim encircling the head was found to be more effective in blocking UVA radiation than a hat with only a front or side brim.

본 연구는 모시대 분말을 첨가한 현미분말에 당의 종류를 달리하여 제조한 다식의 품질특성을 분석하였다. 명도(L값)의 경우 대조군인 꿀 첨가군과 물엿 첨가군은 같은 값을 나타낸 반면 플락토올리고당 첨가군과 이소말토올리고당 첨가군은 유사한 값을 보였다. 적색도(a값)의 경우는 플락토올리고당 첨가군과 이소말토올리고당 첨가군은 대조군에 비해 유의적으로 낮은 값을 보였다. 황색도(b값)에 있어서도 플락토올리고당 첨가군과 이소말토올리고당 첨가군은 대조군에 비해 유의적으로 높은 값을 나타내었다. 기계적 특성에서 탄성과 응집성은 유의적인 차이가 없었으나 경도, 검성, 씹힘성은 유의적인 차이가 있었다. 경도, 검성, 씹힘성은 BRSM과 BRIM보다 대조군이 낮게 나타났다. 관능평가 결과, 맛의 경우 꿀 첨가군, 플락토올리고당 첨가군은 비슷한 점수를 보였으나, 이소말토올리고당 첨가군과 물엿 첨가군은 꿀이나 플락토올리고당 첨가군에 비해 유의적으로 낮은 점수를 나타내었다. 조직감은 다른 첨가군에 비해 플락토올리고당 첨가군이 유의적으로 높은 값을 나타내었다. 전체적인 기호도의 경우 꿀 첨가군과 플락토올리고당 첨가군은 같은 값으로 이소말토올리고당과 물엿 첨가군에 비해 유의적으로 높은 점수 차이를 나타내었다.

To reduce farmer's stress from solar radiation and ultraviolet radiation(UV), the sunshade hat with a large brim and special structure for ventilation was developed and tested with manikin heads outdoors at previous study(Kim and Choi, 2002). To evaluate the protection efficiency of the sunshade hat, human trial test was performed at outdoors. The results were as follows; Skin temperatures(7 sites), heart rate, temperature inside the hats, temperature and relative humidity inside clothing on the back in wearing developed sunshade hat were significantly lower than those in wearing the controlled hat. In subjective sensation, subjects answered to feel significantly hotter, more humid and more uncomfortable in wearing the controlled hat. But relative humidity inside the hats was significantly higher in wearing developed hat. In rectal temperature, there were no significant differences between two hats.

A safety helmet is considered the last gear to protect workers from harmful and dangerous events occurring on industrial sites. Recently, interest in the importance of personal protective equipment design reflecting individual characteristics has been emphasized to improve usability and convenience. However, it has been found that if it is inconvenient to wear or has poor work efficiency, it will not be used well or will be used incorrectly. In this study, an investigation was performed with 35 questions, direct observation, and intensive interviews of construction workers to determine the inconvenience and problems of wearing safety helmets. Moreover, managers of 9 construction sites in 6 cities were asked about the performance and design of safety helmets. As a positive answer, it was found that the brim (awning) of the safety helmet was shortened to give the safety glasses a light-shielding function. In addition, an upward adjustment all-in-one type safety helmet was requested. On the other hand, it was revealed that negative answers felt uncomfortable due to the brim (awning) on the front of the helmet. Based on the survey results, a new helmet model suitable for construction site activities was presented, and wearability improvement determinants were discovered through performance and design improvement.

The purpose of this study were to investigate a preference and demand performance of UV protective hat for outdoor sports activities. Data collected from 259 adults from survey were analyzed by frequence analysis, crosstabs, t-test, and ANOVA using SPSS 17.0. The results are as follows. A demand performanc of UV protective hats were a demand performance for designs, colors, fabrics, lightness, UV protection, and easy care. It showed that the respondents worn the hats for skin health and didn't wear for sun block. The demand performance of UV protective hat showed difference according to gender and age. The favorite type of UV protective hat was cap, and there was no difference between young and old age. Male preferred the cap styles, while female preferred the wide brim styles for UV protection. The preferred fiber contents of the respondents were cotton and functional fiber.
