The purpose of this study is to analyze the effect of problem solving ability and satisfaction of university students who are pre-technology teachers in woodworking products(birdhouse) making program using design thinking. Survey responses are analyzed by statistical programs(SPSS ver.20) such as satisfaction, confidence in problem solving, difficulties and causes of difficulties according to gender and grade of 33 students who conducted experience programs in extra-curricular programs to improve creativity and problem solving ability. The main conclusions of this study are as follows: First, the average of total satisfaction about experience programs is 4.39, which is somewhat high. The highest average response is 'feelings of accomplishment' and 'advice in the surroundings'(M = 4.46). There is no significant difference between male and female, and grade. The students interest in group-based different birdhouse woodworking together with the help of the surrounding people by the process of design thinking rather than practice to follow. Therefore, I'd like to recommend to other students due to this program shows a high self-confidence, sense of accomplishment, and satisfaction. Second, the total average response of students 'self-confidence for problem solving at the group based making experience program using design thinking is 3.80. In result of group activities, the students have self-confidence of 'problem-solving ability and deal with difficult situations'. Later, in making programs, complementing difficulties of making can enhance the satisfaction of the students. Third, in the survey questionnaire related with problem solving ability confidence, between 'I have the ability to solve many problems' and 'I always have the ability to cope with new and difficult business situations' show the highest correlation. Therefore, in order to improve self-confidence of problem solving ability, it is necessary to prepare teaching learning programs that can strengthen problem solving ability. Fourth, in the new design and making process not a given product design, the most difficult step is 'the process of rework and modifying idea product'. The main reason that students have difficulty in the production process is 'lack of knowledge and ability to produce'. To make various woodworking products using design thinking process, it can be helpful to make works if you have enough training on woodworking and design thinking before product making. The students' satisfaction about team-based learning using design thinking that helps improving creativity and problem solving ability is high. Therefore, the result of the research in other making activity program that design thinking is applied and analyzed can improve students' problem solving ability.

In this study, the characteristics of natural and synthetic adhesives used in woodcraft were evaluated. The pattern of deterioration of wood and adhesives according to changes in temperature and humidity were compared. For materials, one type of anlmal glue, three kinds of polyvinyl acetate adhesives, one type of epoxy adhesive and one type of zelkova wood were selected. Characteristics of physical and chemical characteristics, weather resistance and drying speed assessment were carried out. The adhesion characteristic evaluation showed that the adhesion strength of anlmal glue and one type of polyvinyl acetate adhesive were 6.54 N/㎟ and 7.01 N/㎟, pH meter of anlmal glue and polyvinyl acetate adhesives was pH 7.03 and pH 3.32-3.59 which were range of available as an adhesive. According to the test results of weather resistance, epoxy adhesives had the highest decreasing value in adhesion strength after deterioration. In the reversible test of the adhesive, it was found to be highly reversible in NaOH, a soluble solvent excluding epoxy, but attention is required when using the wood since it may show discoloration during processing.

This basic research was conducted to support the development of woodcraft bio-adhesives using peach gum, which is the resin produced by peach trees. The synthesis conditions of these adhesives were optimized by performing 144 experiments. The application potential of peach gum adhesives was explored by comparing their properties with those of three natural adhesives and four synthetic adhesives. The best adhesive strength was obtained by dissolving the resin in 80 mL of distilled water containing 1.5 g NaOH, 1.65 g H₂O₂ ( pH 8.0-9.0), 0.5 g NaClO, and 0.5 g H₂BO₂. The adhesive strength, which showed minimal changes and excellent reversibility, was 125.39 kgf/cm². Ultraviolet radiation-mediated deterioration in strength in the absence of total aerobic bacteria was negligible (△E^*ab = 2.75). These data confirm the potential value of peach gum-based bio-adhesives for woodcraft as well as their utility as alternatives for natural and synthetic adhesives used for the manufacture and restoration of handicrafts and preservation of cultural assets.

school. This study was carried out by literature review. Values of woodworking in extrinsic viewpoint were justified as well-balanced development between left brain and right brain, effective improvement of creative problem solving skill, formation of affirmative attitude toward woodworking, and obtaining method to use tools and equipment effectively. Values of woodworking in intrinsic viewpoint were justified as students' instinct liking of woodworking, psychological stability, and implanting self-confidence in students. In addition to these, woodworking has more educational values. Such values should be justified in the following studies.

브릳지스톤 타이어는 73. 6.23 고무 기자회의 요망을 받아 들여 동사의 신예스틸타이어전문공장인 회목(도찌기)공장을 처음으로 공개했다. 스틸타이어 전문공장이라고 하는 것은 이것이 일본 유일의 것이며 보통의 라디알공장조차 비공개를 원칙으로 하고 있는데가 많은가운데 건설, 2년 2개월이라고 하는 짧은 조업기간임에도 불구하고 공개에 응했다는 것은 동사의 스틸타이어에 기울이는 열의와 기술적 자신을 말하는 것이라고도 볼수 있어 주목되었다. 또한 동공장은 74년 4월완전일관 공장으로 된다. 이하는 회목공장의 견학기이다.

북미 원산인 아까시나무는 우리나라에 1900년대 초에 도입되어 원료림과 황폐지 복구용으로 조림되었으나 점차 산림이 녹화되고 이제는 산림의 오히려 망치는 나무로 오인되어 사람들의 미움을 받고 있는 실정이나, 우리에게 아까시아 꿀과 5월에 아까시아 향을 뿜어내며 꽃잎이 휘날리는 아름다움 전경은 많은 사람에게 추억으로 남아 있다. 또한 목재는 강도가 좋아 차량재, 목공예용으로 사용되어 버릴 것 하나 없는 우리에게 즐거움만 주는 나무이다. 하지만 이러한 나무에 해충이 피해를 주니 이들의 종류 및 생태 그리고 방제에 대하여 소개하고자 한다.

X-ray computed tomography (X-ray CT), which is often applied to the investigation of the interior structures of cultural properties, is very useful for studying production methods used in lacquerware that would otherwise be difficult to observe with the naked eye. Lacquerware inlaid with mother-of-pearl is an important subject in the study of traditional Korean craft. However, it can be a challenge to specify the production methods used in the framework of a lacquerware item unless the object has been structurally damaged. Studies of lacquerware inlaid with mother-of-pearl have thus far focused on the techniques of lacquering and of inlaying the mother-of-pearl. Production methods for the framework of lacquerware has received little academic attention. This study conducted X-ray CT on a lacquerware item from the Joseon period to reveal the materials and woodworking techniques used for the framework. The study revealed that softwood was used for the framework, and the post (gidungmok) and apron (soemok) were joined using a three-way miter joint (sambang yeongwi jjaim). Other pieces were joined with nails.

A Goryeo-era mother-of-pearl-inlaid incense box in the collection of the National Museum of Korea, a major example of Goryeo dynasty cultural heritage, presents a comprehensive view of the production techniques and aesthetic expressions of its time. This study investigated the type of wood and the techniques used to make the framework of the box, knowledge that was necessary for its restoration. It also examined anatomical characteristics of the shell providing the mother-of-pearl. The incense box was found to be made of cedar, which suggests that there was trade in cedar with Japan. A band was attached to the lower portion of the lid by applying what the author describes as a "wrinkle-bending" technique at the corners. Wooden pegs were used to combine the top and side panels, probably for more efficient use of the thin wooden boards. The investigation of the anatomical features of the mother-of-pearl inlay identified a laminated structure of thin plates. These features are observed in certain shellfish, and further study would be required to accurately identify the type of shell.

Postmodernism has blurred the line between design and art. We would like to suggest a design case that took diversity in the modern era that harmonizes functionality and shape of the top board of a furniture and trend of the role of furniture and objet into consideration. This study aims to project a new role into space via convergence of objet that has aesthetic function and furniture design that plays practical role in space. Thus, furniture design attempts to combine ceramic and carpentry and demonstrate the value and potential the combination possesses. By creating a distinct design from previous furniture that had visual limitations with ceramic bridge that adopted existing piling method in ceramic design, we expect a fresh blend of furniture and space that encompasses a different sensation from color and texture of soil and glaze, unable to attain from simple wood.

Most of Korea's Kyungmaedorock(auction book: 競賣圖錄) and pictorial record of exhibitions in the modern times were usually published in the 1930s. Although 1930s were periods of the Great Depression when economic slump continued because of the aftereffect of the slump in the stocks issued by the US in 1929, during this period, Japan began regular continental invasion starting from invasion of the northeastern area of China. To curio dealers, the 1930s were 'boom period of curio transaction' and in urban cultural aspects, the period is evaluated as the one when the first step of modernism was formed. Collection, photo-printing and arrangement of the data related to modern exhibitions including the Auction Book being published at that time are very important because they enable us to know characteristics of fine arts in the transition period from paintings & writings to fine arts in addition to enabling us to revert the circulation history of our paintings & writings and curios. Furthermore, these data will become important data for reconstitution of the circulation history of the Eastern Asia's modern art works. Although the pictorial record of Joseon's Exhibitions of Chinaware and Wooden Works(朝鮮陶磁木工展) is a small and thin one, it records our country's high level chinaware and wooden works. Although we can't know the exact time for 'Joseon's exhibitions of chinaware and wooden works', they are assumed to have been held in Tokyo, Japan in the 1930s and there seems to have been sale of works, too. As such, studies of the books such as the auction book and exhibitions under Japanese imperialism have the first importance in the fact that through which we can examine the course of outflow of our art works to Japan. Furthermore, they can be studies of art-sociology that examine flow and phase of recognition and taste of art works of those days. And from now on, comparative studies of auctions and exhibitions being held in Japan such as Tokyo, Osaka and etc. as well as art markets in Seoul during modern times would also be necessary.
