본 연구에서는 전통풀의 하나인 밀가루 풀과 통밀 삭힌 풀로 푸새한 직물의 물성을 12년의 시차를 두고 비교 검토하여 경시적 변화를 고찰해 봄으로써 전통풀의 안정성을 규명하고자 하였다. 12년 전후의 푸새직물의 비교에서는 통밀 삭힌 풀로 푸새한 직물이 삭히지 않은 밀가루풀로 푸새한 직물보다 인장강도, 백도는 증가하며, 강연성, 공기투과도는 감소하는 경향을 나타내었는데 이는 통밀 삭힌 경우가 삭히지 않은 밀가루보다 탄수화물 함량도 많고 노화 전반에 관한 안정성이 높은데 기인하므로 삭혀서 풀을 만드는 선조들의 지혜가 과학적임을 증명할 수 있었다. 또한 삭히지 않은 밀가루 풀로 푸새한 직물의 경우에는 주사전자현미경에 의한 표면관찰 결과 직물조직 사이에 경화된 이물질이 발견되었으나 통밀을 삭힌 풀로 푸새한 경우는 발견되지 않아 통밀 삭힌 풀에 의한 푸새 직물의 경우가 경시적 변화가 적게 나타남을 알 수 있었다. The objective of this study was to investigate stability of traditional starch sizes according to time. The properties of wheat flour and fermented whole-wheat flour were studied. And comparison of stiffness, tensile strength, air permeability, whiteness, and surface observation of cotton fabrics sized with wheat flour and fermented whole-wheat flour before and after 12-years were examined. The amylograph data indicated that ISF-W(Isolated starch flour- white) have good pasting properties than NWF(Natural wheat flour) and ISF-B(Isolated starch flour- light brown). The cotton fabrics sized with ISF-W had higher tensile strength and whiteness, and lower stiffness and air permeability than those of NWF as the time takes 12 years. We identified the stability of traditional starch size using scanning electronic micrograph.

In this study, research was conducted on $Vectran^{(R)}$ fibers (highly heat resistant, high strength, lightweight industrial fibers) to determine their suitability for use in the development of hybrid wires and cables. Vectran fibers were heat-treated to various temperatures and treated with HCl and NaOH solutions under various conditions. The effects of heat, HCl, and NaOH treatment on the creep behaviors, mechanical properties, and surface properties of Vectran fibers were examined. X-ray diffraction (XRD) analysis was used to investigate crystallinity changes; while Fourier transform infrared spectroscopy (FT-IR) and X-ray photoelectron spectroscopy (XPS) were used to analyze chemical structure changes resulting from degradation. Analysis showed that the mechanical properties and crystallinity of Vectran fibers changed significantly by treatment at temperatures greater than $250^{\circ}C$. Although HCl treatments did not cause significant changes, NaOH treatments resulted in considerable changes in the surface and mechanical properties and crystallinity. FT-IR and XPS analyses indicated that the degradation resulted from the hydrolysis of ester bonds in the fibers.

장황용 풀에 사용된 약재에 관한 문헌연구

본 연구에서는 장황의 의미와 장황의 중요한 재료인 풀의 제조방법을 문헌을 통해서 살펴보고 풀의 제조에 첨가되는 약재들의 특성을 연구논문과 실험결과들을 통해 그 기능성을 살펴보았다. 장황은 표구의 옛말로 중국으로부터 종이 및 종교의 유입과 함께 자연스럽게 유입되었고 장황물은 의례용으로 중요한 도구로써 그 역할을 하였을 뿐만 아니라 인간의 문화를 후대까지 전해주는 역할을 했다. 이러한 장황문화는 한국, 중국, 일본이 그 나라의 자연환경, 사회문화, 그리고 민족성에 맞게 발달하여왔으며 그 민족의 정신문화를 후대에 전해주고 있는 것이다. 본 연구에서 다루고 있는 장황에 사용된 약재도 나라별로 조금씩 다른 재료를 사용하고 있다. 한ㆍ중ㆍ일 모두 백급, 백반, 황납 등을 사용하며 중국의 경우 유향, 산초 등을 사용한 예가 있고 일본의 경우 마취목이나 우치말차 등을 사용한 예가 있으며 우리나라의 경우 호초, 용뇌, 사향, 천궁, 운향 등 향의 재료를 좀의 예방을 위해 사용하였으며 유연한 배접효과를 주기 위해 무즙을 사용한 기록이 있었다. 실험적으로 백급과 백반은 항균성이 있는 것으로 나타났으며 유향과 호초는 항균성이 낮은 것으로 나타났다. 이상 본 연구는 현재 사라져가는 장황문화를 계승하고 전통기술의 우수성을 밝혀 이를 현대에 활용할 수 있는 자료를 제공하고자 하는 것이 본 연구의 목적이다. The purpose of this study is to review literature on how to prepare paste for jangwhang, drawing out basic information necessary for supporting and developmentally applying scientific properties of jangwhang. Jangwhang was introduced from China naturally along with paper and religion. Stuffs of jangwhang were not only used for rite purposes, but also contributed to transmit human culture from generation to generation. Developments of jangwhang culture were different among Korea, China and Japan depending on those countries' natural environments, social cultures and national sentiments. In each of the countries, jangwhang culture played a role in transmitting the culture of national spirit from generation to generation. But many of our cultural assets in form of painting, which had been treated with jangwhang, were damaged and lost due to a number of wars that occurred during this nation's history. Any of such assets, even if remained today, find themselves adapted with the techniques of Japanese mounting. To keep and preserve jangwhang culture of our own is the very way of safely transmitting the culture of our national spirit and precious cultural assets to the future generation. It is the duty of the present generation. This study find that Chinese herbs as materials of paste for jangwhang were different in kind among the countries. This is attributed to the fact that the countries were different from one another in natural environment. Main materials of paste for jangwhang are baekgeup(bletillae rhizoma), baekban(alum) and whangnap(yellow beeswax). But it is recordedly found that some other materials were also used to prepare the paste, for example, yuhang or hunyukyang(frankincense) in China and machwimok(pieris japonica) or uchimalcha in Japan. Especially in this nation, yongnoe(borneol), sahyang(musk), cheongung and unhyang(angelica polymorpha) were used as other materials of paste for janghwang in order to prevent moths and, sometimes, radish juice was used in order to make better the effect of pasting. Our ancestors utilized plants, trees and earth around them as means of maintaining our traditional culture. In association, we need to scientifically investigate and more develop our ancestors' wisdoms. Finally, this researcher hopes that this humanistic study helps set a stronger base on which our traditional scientific technology can be more developed and further that our society develops itself into an arena where not the creation of high added values, but the coexistence of human and nature is sought towards.

The purpose of this study was to enhance the flame retardancy of cotton fabrics that are largely used for interior textiles including sleepwear, sleeping gear, and curtains by preprocessing untreated cotton fabrics. Mercerization and plasma treatments were used for preprocessing. The variables of mercerization were treatment time (5, 10 min) and temperature (0, 20, $80^{\circ}C$). The variable of plasma is treatment time (5, 10, 15 s). To compare the properties and dynamics between non-treated fibers and preprocessed fibers, SEM, EDAX, weight-gain percentage, transfer characteristics of water, flame retardancy, and a KES-FB system were used. The plasma-treated fabrics exhibited less property change than the mercerization-treated fabrics. The mercerized fabrics had more outstanding features in terms of flame retardancy. The best flame retardancy among the experimental conditions was observed in the condition of processing for 5 min by low-temperature mercerization.

The purpose of this study was to evaluate the mechanical and comfort properties of fabrics for the development of fire-retardant work clothes. Specimens used in this study included six fire-retardant and welding work clothes and one fire-retardant fabric. Although all samples were made of cotton, samples A, B, and C had fire-retardant textile certifications. In addition, sample G was a fire-retardant fabric with conductive threads. The mechanical properties of all specimens were measured using the Kawabata evaluation system for fabrics (KES-FB). Results showed that A, B, C, and G had low values, in terms of tensile properties, of tensile energy (WT), but excellent shearing and bending properties. Thick cotton working clothes were observed to have high shearing prepertics, and as to surface properties, twill fabrics were found to have smoother texture. For the comfort properties of fabrics, A, B, C and G had high $Q_{max}$ and thermal conductance values, therefore they were better in terms of cool touch. However, they were found to have low air permeability.

The purpose of this study is to improve interfacial adhesion strength of carbon fiber reinforced hybrid composites by physical and chemical treatment. Ultrasonic irradiation was used as physical and chemical treatment relatively. The morphologies of fracture-section and surface of carbon fiber fabric/CNT reinforced hybrid composites were observed by SEM. The morphologies of specimens treated with ultrasonic showed rougher and more compact surfaces than those of untreated specimens. The specimens treated with ultrasonic showed higher impact strength compared with untreated specimens. This result showed ultrasonic irradiation is one of the effective method to improve interfacial adhesion strength between carbon fiber and matrix.

Purpose: Development of a standardized guideline and assessment tool is necessary. Therefore, the aim is to investigate the current state of enteral feeding management and to develop a basis for a standardized guideline. Methods: From July 1, 2010 through June 30, 2011, this study was conducted retrospectively for 100 patients who had enteral feeding more than once only in the Intensive Care Unit, after General Surgery at Severance Hospital, Yonsei University College of Medicine, Seoul, Korea. The analysis was based on the following factors; age, diagnosis, name of the operation, period of start and the end of enteral feeding, method of injection, flushing method, residual volumes of the stomach, location and the size of the tube, medication through tubing, and complications related to enteral feeding. Results: The mean age of the patients was 60.5, 65 men and 35 women. There were 30 malignant tumors of the hepatobiliary system and pancreas, 8 gastric and duodenal cancer, 4 colon and rectal cancer, 11 peritonitis, hemoperitoneum, and bowel obstruction, and 47 others. The average period of performing enteral feeding was 11.7 days and the locations of enteral feeding tube were stomach 56%, jejunum 39%, duodenum 3%, and undescribed 2%. The methods of enteral feeding were as follows; continuous feeding 19%, cyclic feeding 75%, intermittent and bolus feeding 3%, respectively. Only 1% of patients were on flushing and 16% on stomach residual. The most common complication of enteral feeding was clogging of the tube (5%). Conclusion: Due to the lack of detailed charting related to enteral feeding, we were unable to analyze the statistics on the relevance of complication which was the primary endpoint. As a result, development of a standardized protocol on charting enteral feeding is suggested for optimal enteral nutritional support.
