  • The object of this study is to compare properties of massive fly-ash concrete with plain concrete. Two concrete mixtures comprising two batch each $1.0m^3$ in volume, were made from ready mixed concrete batch plant. The water-to-cementitious materials ratio was kept constant at 51.4%. Therefore, massive concrete specimen($W800{\times}D800{\times}H800mm$) was cast from ready mixed concrete to analyze history of temperature and core strength properties. Bleeding, time of slump loss and time of setting of the fresh concrete were measured. In order to estimate the properties of massive fly-ash concrete in hardened concrete, non-destructive tests such as rebound hardness, ultrasonic pulse velocity and maturity were performed and analyzed.

  • The purpose of this study was to examine the state of smoking among some college students, the smoking motivation of smoker students, what made them quit smoking and how they got ready for giving up smoking, as smoking had a huge impact on national health and there was a desperate necessity for preventive antismoking education programs to let students keep away from smoking. After a survey was conducted with self-administered questionnaires from October 1 through November 1, 2006, the responses from 400 students were gathered, and 384 answer sheets were analyzed except 16 incomplete ones. The findings of the study were as follows: 1. By gender, 62.4% of the male students and 28.6% of the female students were smokers, and the state of smoking was statistically significantly different according to their gender(p<0.05). 2. The largest number of the male students, which accounted 44.1%, started smoking in their high school days, and 39.5% of the females did that in middle school. As for a daily mean amount of smoking, 41.8% of the male students, the greatest percentage, smoked 10 to 19 cigarettes a day, and one to nine cigarettes were most common among the females, which represented 57.9 %. But the gap between the two was insignificant(p>0.05). As many as 83.6% of the males and 86.8% of the females had ever attempted to quit it. 3. Concerning awareness of antismoking policies, they felt that a raise in cigarette price would lead to less smoking, and that antismoking advertisement or posters through television or newspaper would deliver the same results as well. There was a statistically significant difference among their awareness(p<0.05). 4. Regarding preparation stage for quitting smoking, 31.3% of the male smokers had no intention to give it up, and 23.2% considered it. 36.7%, the largest percentage, got ready to refrain from it. Among the female smokers, 34.2% had no plans to abstain from smoking, and 36.8% took it into consideration. 23.7% got ready to do that. The females who got ready for that were outnumbered the males who did. 5. As to connections between the state of smoking and relevant knowledge, the students didn't have a good knowledge on that, and a statistically significant difference existed between the smokers and nonsmokers in smoking knowledge. 6. As for knowledge about oral diseases, they were highly cognizant of the relationship of smoking to tooth discoloration, nicotine stomatitis and bad breath, but they didn't know well about its relationship to delayed recovery from dental treatment, implant failure and ozena. Their smoking condition made a statistically significant difference to their knowledge(p<0.05). In the future, sustained research efforts should be channeled into determining how much smoking affects health and concerns oral diseases, and antismoking counseling programs should be prepared to bolster people's awareness of oral health.

  • Since WWII and the Korean War, Korean modern fashion has been americanized by claiming, displacing with, and fusing with the traits of American fashion. The purpose of this study is to observe and analyze the traits of Americanization in Korean fashion, focusing on the designs of Nora Noh fashion from the 1950s to the 1980s. Nora Noh (1928- ), one of the first Korean fashion designers, who launched the first fashion show in 1956, introduced ready-made dresses to Korean fashion industry in 1963 for the first time, and later in the 1970s and the 1980s, exported Korean-made fashions to the U.S. market. For such purpose, this study first provides the theoretical backgrounds of Americanization in Korean fashion history and then conducts a case study by analyzing photographic materials. In case of Nora Noh fashion, the traits of Americanization can be defined as functionality, popularity, and hybrid. (1)Functionality in Americanized Korean fashion was expressed through simplicity, practicality, and usefulness. Noh's "homewear" style and exported silk dresses are the examples of the functionality. (2)Popularity was shown in kitsch images of materialistic and consumer culture. It was expressed in ready-made dresses and trendy styles of mini skrits and bell-bottom pants. (3)Hybrids of various multi-culture exist in American culture and fashion. In Noh's designs, traditional materials and the print patterns inspired from traditional motifs were used to add Korean nuances in Americanized fashion.

  • For the establishment of ready made Hanbok for the people in their 20's this study aims to develope Bagi-chogori pattern that revives the esthetic quality of the traditional Hanbok as well as comfortably fit the body. Direct method was used in Measuring the 33 parts of men which was selected as items needed for the analysis of the body and the development of patterns. In accordance with the body measurement and the analysis of the result the bust girth and height which has interrelation was chosen as the standard size for the development of pattern. Men's Baji-chogori(Korean traditional Jacket and Pants) which doesn't request fitness for instance we drew out a cross table by giving 5cm intervals each for breast waist hip girth and height. Size system of Baji-chogori was 4 steps. 1st was bust 95cm height 165cm 2nd was bust girth 95cm height 170cm 3rd was bust girth 100cm height 175cm and the 4th was bust girth 105cm height 180cm. In the case of Men the grouping of bodies was attempted by concentrating on the difference of the drop amount(Bust girth to hip girth), However 90% of men in their 20's showed a silhouette of an inverted triangle. Therefore attempt for an additional grouping wasn's Only calculation concerning the ease amount of items such as bust which and length was considered to enhance the silhouette of Hanbok when worn. Men's body for instance have a tendency to change to a rectangular shape as they get older. specially the abdominal girth trend to increase greatly. So study and development of pattern should be made for all age groups.

  • This study provides basic data for the development of jacket patterns which reflect designs corresponding to the body shape features and preferences of obese women in their 20s and 30s by understanding problems they may encounter in wearing a ready-made jacket by researching the reality of ready-made tailored jacket wearing and their design preferences. A survey was conducted by sampling 82 obese women (over $25kg/m^2$ BMI) between the ages of 20 to 39. The details of the survey consists of general information, interest rate and importance rate on clothes, reality of wearing and purchasing jackets, measurement fits per each part, and preferred designs. SPSS 14.0 was used to analyze the data. The results showed that 76.8% of obese women wore their jackets less than 5 times a month. Those in the 20s wore the jackets more frequently than those in the 30s. The reasons for not wearing jackets frequently included uncomfortableness in activities and unavailability of the correct size. A total of 55% of the total preferred the fitting to be relatively smaller than the body size or tightly fitting. Although in the past, there was a tendency to wear a loose fit to cover the body shape, currently even obese body shapes avoided the loose fit as the tight fit is the trend. In terms of the satisfaction rate for the measurements per each part of jackets, there was a low satisfaction rate for most of the items. For the circumference items such as waist length and chest size, people responded that they were too small and for the length of items such as the length of jacket and sleeve length, people responded that they were too long. This was because the readymade clothes brands increase the length of items and circumference items in uniform in the same intervals when producing large sizes. Both those in the 20s and the 30s preferred a tight fit. In terms of preferred fabric, a wool/spandex mix was most popular and then cotton/spandex. This shows that they prefer those fabrics which allow an excellent activity while maintaining the exterior well. In addition, they preferred black color with no patterns because they wanted their body size to look reduced and did not want to receive any attention.

  • 국장은 한 국가를 상징하였던 왕의 장례식이다. 국장에 필요한 상구류를 마련하여서 원활하게 치루어야 하기 때문에, 각 방에서 제작한 각종 상구들은 그 자체로 상당히 중요성을 지니고 있다. 임금의 옥체를 실은 제궁을 직접 운구하는 대여와 견여는 국장에서 소중히 다루어야 할 핵심적인 상구이다. 대행왕을 살아있는 것 이상으로, 모든 사람들은 국장에서 그를 엄숙하게 모셔야 했다. 그러나 국장도감에 소속된 각 방에서 제작한 상구들은 대행왕과 직 간접적으로 관계가 있거나 왕의 권위를 상징하고, 왕권계승과 같은 왕통과 관련있으므로 매우 중요하다. 발인은 왕의 마지막 권위를 드러내는 장이며, 시간이다. 따라서 국장도감은 대행왕의 발인을 살아서 행차하는 것같이 진행하였다. 이를 통해서, 왕의 현세와 내세를 동일한 선상에서 서 있다는 인식하에서 발인을 준비하였음을 알 수 있다. 살아서 왕의 행차 시에 활용하였던 다양한 각종 기물들을 흉례인 국장 발인 시에도 유사하게 활용하였다는 점에서 이를 입증할 뿐만 아니라 생사관도 엿볼 수 있는 장면이기도 하다. 국가는 공권력으로 다양한 공장 분야와 많은 공장들을 동원하여서 정해진 기간 내에 다양한 상구들을 마련하여서 국장을 치루고자 하였다. 서울과 경기지역을 포함해서 전국 각지에서 활동하고 있었던 공장들과 신분이 비천할지라도 일정 수준의 기술을 지니고 있는 공장들을 국정도감으로 불러들였다. 기술과 노동력 제공에 상응하는 급료와 보상하고 받음으로써, 국가와 공장은 지속적으로 상호보완적인 관계를 계속 유지하였다. 각방에 소속된 공장들은 기존 상구를 활용하였고, 새로운 제작과 보수를 통해서 국장용 상구를 정성을 다해서 마련하였다. 조선시대 국장은 공장들의 '기술 잔치'일 뿐만 아니라 '기술의 총합체'라고 말할 수 있다.

  • Designing a morphologically well-fitted hip implant to a patient anatomy is desirable to improve surgical outcomes since a commercial ready-made hip implant may not well conform to the patient joint. In this study, biomechanical stability of patient-specific hip implants with two different stem lengths was compared and discussed using a 3D finite element analysis (FEA). The FEA results in this study showed that an increase in stem length brings about more the peaked von-Mises stress (PVMS) in the prosthesis and less in the femur. However the decrease in von-Mises stress in the femur causes stress shielding phenomenon that usually leads to considerable bone resorption. Although, in biomechanical stability point of view, this work recommends the use of smaller stems, the length of stem must be determined by considering both the von-Mises stress and the stress-shielding phenomenon.
