Recently, it has been reported that chemical hair coloring can cause allergic reactions, the toxicity issue of chemical hair color was issued. Therefore, there is an increasing interest in the hair coloration technique using non-toxic and bio-compatible hair color gotten from natural resource. In this study, the possibility using fermented Indigo as natural hair coloring agent was investigated. Bleached hair samples were dyed using Indigo, and the effect of dyeing frequency, the physical change after dyeing, color, surface and cross-section characteristics, and tensile property were also studied. In addition, the protection property of cationic detergent finishing on damaged hair samples were also studied. The following conclusions are made; 1. While bleached hair samples with low value showed the negligible effect of repeated dyeing, bleached hair samples with high value showed the good effect of repeated dyeing. 2. Hair sample dyed with Indigo showed a high light-fastness, however, tensile strength and elongation showed very low values (high damage on hair sample). 3. Cationic detergent finishing did not affect on the colorfastness because of decoloration after dyeing, however, it increased the smoothness of hair sample, and therefore, can use as protectant of damaged hair. 4. Hair scale was damaged after dyeing. It seemed that the alkali, potassium carbonate, increased pH of dyeing bath to 11, as a result, the hair was swollen, weaken, and dissolved on the prolonged dyeing time. Dyed hair sample became stiff and fine. 5. The color difference was 4.62 (a high fastness value) in the test of sunlight exposure, shampoo, cationic detergent finishing, and acid perspiration fastness.
People are surrounded with numerous sounds. The sound is generated from nature and people. For example, the sound enables people or animal responsive to instinctive action. Music or fine arts are presented differently by its distinctive medium. On the other hand, those art forms are similar in a way that people uses right side of brain and intuitions for creative effects. Conjunctions between sounds and visual arts have been progressed to data. From art forms in subjective views to art forms using high technology such as the computer, experiments for sounds visualization are practiced constantly. For that reason, intrinsic attributes of sounds in design area and distinctive qualities are discussed in this study. With respect to existing category of studies and consideration of the tendency in recent researches, the object is to propose direction for the study in regards to methodology of design, which is reconstructing visualized expression.
Clostridioides (Clostridium) difficile is a Gram (+), anaerobic, spore forming, rod shaped bacterium that can produce toxin. The objective of this study is to reveal the presence of C. difficile in meat products, to analyze the ribotype diversity by PCR and to evaluate the antibiotic susceptibility of isolated strains. The organism was isolated in 22 out of 319 (6.9%) examined meat product samples and 9 out of 22 (40.9%) isolates were identified as RT027 and all isolates had the ability of toxin production. In terms of antibiotic susceptibility, all isolates were susceptive to amoxicillin-clavulanic acid, tetracycline and vancomycin and 21 (95.4%) isolates to metronidazole. On the other hand, imipenem and cefotaxim resistance was observed in all. In conclusion, the results of this comprehensive study conducted in Turkey deduced the presence of C. difficile in different meat products. Therefore, these products can be evaluated as a potential contamination source of C. difficile from animals to humans especially for elders, youngsters, long terms wide spectrum antibiotic used and immuno-suppressed individuals.

Finger electrodes on a crystalline silicon solar cell are required to be constructed as narrow and thick as possible in order to minimize shading losses and electrical resistance. The most common means to construct high-aspect ratio finger electrodes has been screen-printing, but it has difficulty achieving fine finger electrodes because the as-printed finger width is generally wider by 1.3-2.2 times the screen opening width. Consequently, it requires an extremely small screen opening (below $30{\mu}m$) in order to achieve a finger width below $40{\mu}m$. However, the use of such a small screen opening could result in various problems, such as high printing pressure, defective transport of silver paste, and high electrical resistance due to unfavorable mesh marks left on the finger electrodes. In this study, dispensing printing with a screw pump is introduced as an alternative to conventional screen-printing and its unique traits in the front side metallization of crystalline silicon solar cells is discussed.
This study understands rockers of today and supplies basic data of design and manufacture studying pattern change of rockers arisen in West, there is the purpose. Also, this study is investigated by dividing theoretical background of rockers, 7 kinds of American traditional rockers and European rockers from 18th century to opening part of 20th century and contemporary rockers since 20th century. The theoretical background and the style of 2 rockers (Windsor rocker, Boston rocker) were investigated to study the stylistic changes of rockers. Originally a rocker was invented by a European farmer around 1700. It developed to a household which equip practicality and comfortablness in the United States than Europe. Early rockers in a primal form appeared in the 1740s in the United States. American early rockers connected skate to established chair bridge. Rockers are deep connection with family's emotion. Rockers can provide playing functions for children and medically treating functions for adults. Windsor Rockers developed by attaching skate is mammy bench and according to shape of back form bow or hoop-back rocker, birdcage rocker, comb-back rocker. Windsor Rockers formed peculiar American tradition of craftsman furniture through structure that have a unique back of a chair and round seat. Boston Rockers were the first chairs made by mass production method. They show a particular shape with S-curve style seat and rectangular crest at the upper part of the back. Often Crests were decorated by stenciled pattern with curled leaves such as rosettes and scrolled designs.

The styles of contemporary landscape design have diversified since the emergence of Postmodernism in landscape architecture. The diversification was mostly influenced by contemporary fine arts and architecture. This study examines the pluralistic development of Postmodern landscape design through the investigation of the influences from those sister arts. In this point of view, the main approaches of Postmodern landscape design are thought to be classified into three categories;'the formal abstract approach', 'the figurative approach' and 'the new picturesque approach'. The first category of the formal abstract approach was formulated with the concepts and vocabulary of Minimal Art and Installation Art. Its representative icons such as 'point grids' and 'stripes', and the main concepts such as the sense of 'flahess', 'expansion' and 'materiality' are mostly thought to be originated from these art forms. The second category of the figurative approach is characterised by the concepts and vocabulary of Pop Art and New Image Paintings. Its representative icons such as 'map' or 'figurative forms' and main concepts like the sense of 'reality', 'context' and 'symbolism' are mostly thought to be originated from these art forms. The third category of the new picturesque approach was formulated with the concepts and vocabulary of Land Art and Late Deconstructive Architecture. Its representative icons such as 'hybrid', 'layer' and 'fold', and the main concepts such as the sense of 'complexity', 'continuity' and 'reversibility' are thought to be originated from these art forms. The research shows that the main stream of contemporary landscape design seems to be gradually moving toward the second and third approach above, in step with the cultural orientation and the dynamism of contemporary urban life. Therefore, the study focused especially on the new picturesque approach which would be in greater need for coping with the hybrid culture today.
Problems This study was aimed to find out the effects of Kindergarten education on primary school child's learning achievement and it's continuance. The specific question to be investigated in this study can he summarized as follows. 1. How did the kindergarten education effect upon primary school child's learning achievement and behavioral development? 2. How did the differences of learning achievement and behavioral development between groups of children attending kindergarten and not attending kindergarten? Methods 1. Subjects One hundred and twenty children of sixth grade and one hundred primary school's teachers were employed 1) Sixty of children were experimented groups who had received kindergarten education. Sixty of Children are Control group who had not received Kindergarten education. The subjects were sampled in N primary school in seoul and Y primary school in Taejeon. Sixty of children were boys and sixty of children were girls. 2) Fifty of teachers were sampled in N primary school in Seoul and Fifty of teachers were sampled in Y primary school in Taejeon. 2. Instrument 1) School cumulative record. School cumulative record was referred to find out the differences of school records on learning achievement in morality, National language, social studies, arithmatics, natural science, gymnastics, music, fine arts and behavioral development in industry, responsibility, coorperation, indeperdence, law abiding spirit between experimental group and control group. 2) Questionnaire paper which constructed 10 articles. Questionnaire paper asked to primary school teachers for effects of kindergarten education. Results The results of date analysis can summarized as follows. 1. Kindergarten education, generally, is regarded effective at least for school work achievement but not so effective for morality and physical education. 2. Kindergarten education is not so effective in all school works of primary school in its continuance since its effectiveness begins to fade away from the 4th grade of primary school. But such continuance tends to be outstanding especially in national language, social subjects and arts. 3. The experiences of kindergarten education is not much helpful to behavioral development during primary school. 4. Primary school teachers recognize that kindergarten education contributes to curriculum work and behavioral development for primary school children.
The purpose of this study was to analyze STEAM learning/teaching program that relates robots and to develop and redesign STEAM teaching/learning program with a robot for elementary and secondary schools. 'Learning with a robot' is considered as one of the best candidates for STEAM education. This article mainly concerns a robot that can be helpful to improve students' interests in learning science and mathematics in schools. As the results of the STEAM learning/teaching program analyzing, the program for elementary schools contained more contents of liberal arts and fine arts, and the program for secondary schools contained more contents of science, technology, and math. In the middle school program, context for learning, class activities of creative design and emotional touch, evaluation, and job and career information were evenly implemented. In the elementary and high school program, there were few information about robotics career. We extracted all robot utilizable subjects and units from school curriculums, and redesigned contents which can be applicable to regular classes for schools. As the result of this study, we conclude that 'learning with a robot' can encourage students' interests in STEM area.
These series articles were written in order to understand rockers of today and to provide basic data of their designs and manufacture studying pattern changes in the West. In the first article of the series reports we already described the theoretical background of rockers and the Windsor and the Boston style among the American classic rockers from the eighteenth to the twentieth century. This article contained the characteristics of the styles of the Shaker rocker, the Wicker rocker, and the Platform rocker. The three periods associated with furnituremaking in the Shaker sect are; the Primitive Era, which lasted from 1790 to 1820; the Classical Era, from 1820 to 1860; and the Final Phase, from 1860 to 1935. The important skills the Shaker needed to make the Shaker rocker are woodturning joinery, seat braid weaving and steam bending for the slats. The Wicker rocker continues to be extremely popular furniture style as the wicker proved equally effective for translating the ornate vine-like motifs popular among Art Nouveau proponents. The Wicker rockers were developed for child's, gentleman's and lady's, and it represents the most diverse forms among the above mentioned styles. However the rocker skates were often clumsy and took up too much room, preventing the chair from being shoved close to the wall and out of the way. These problems were overcome by the Platform rocker. The most important innovation was the technical development of a stationary base, which allowed the chair to rock noiselessly, without skating along the floor. The Modernism of the modern furnitures in America and Europe were affected by the characteristics of the Shaker rocker, the Wicker rocker, and the Platform rocker.
The purpose of this study is to find out the usefulness of color contrast program for 50 high school students through comparing the traditional class and the class using the entry software : understanding, utilization, satisfaction, and interest. The results of the study were as follows: First, in the case of the class results, there were no limitations on colors due to materials in the class using the entry software, so students used various colors that match the theory. Second, the activity class using the entry software showed a positive response in terms of utilization, satisfaction, and interest except for the comprehension area, compared to the traditional class using the paper activity. Therefore, this study proved the effectiveness of the practice activity using the entry software in the color management class.
