This paper demonstrates the possible nondestructive analysis of iron artifacts' metallurgical characteristics using neutron imaging. Ancient kingdoms of the Korean Peninsula used a direct smelting process for ore smelting and iron bloom production; however, the use of iron blooms was difficult because of their low strength and purity. For reinforcement, iron ingots were produced through refining and forge welding, which then underwent various processes to create different iron goods. To demonstrate the potential analysis using neutron imaging, while ensuring artifacts' safety, a sand iron ingot (SI-I) produced using ancient traditional iron making techniques and a sand iron knife (SI-K) made of SI-I were selected. SI-I was cut into 9 cm², whereas the entirety of SI-K was preserved for analysis. SI-I was found to have an average grain size of 3 ㎛, with observed α-Fe (ferrite) and pearlite with a body-centered cubic (BCC) lattice structure. SI-K had a grain size of 1-3 ㎛, α-Ferrite on its backside, and martensite with a body-centered tetragonal (BCT) structure on its blade. Results show that the sample's metallurgical characteristics can be identified through neutron imaging only, without losing any part of the valuable artifacts, indicating applicability to cultural artifacts requiring complete preservation.

With the recent proliferation of Hallyu content, national interest in Korea and the demand for designs with traditional Korean patterns as a motif is on the rise. In addition, as customers' design requirements tend to value more and more detailed and differentiated handcrafted designs, research on the motifs used in nail experts' original nail design development and nail design is continuously needed. Therefore, the purpose of this study is to expand the scope of nail design motifs with high practical value by producing nail design works applying plant patterns of Wadang, used during the Unified Silla Period, and to diversify nail art expression techniques. The research reviewed domestic and foreign literature related to Wadang during the Unified Silla Period, analyzed the collection at the National Museum of Korea, and categorized the motifs based on the characteristics of plant patterns and Wadang during the Unified Silla Period. The tangible motifs are intended to be presented as a fusion of nail art design works that utilizes both flat and stereoscopic art techniques. Through this study, it was confirmed that the plant pattern of Wadang from the Unified Silla Period is an attractive motif that can be expressed in various nail designs expressing Korean emotions and traditional beauty, and furthermore, it can be used as basic data for the idea of various beauty design areas.

Watercolour painting was introduced to China over a hundred years ago, and in the last two decades, it has developed rapidly, presenting a situation of diversified development. While Western-style watercolour painting has been adopted by Chinese painters, they have also expanded on it with their own aesthetic awareness and cognitive styles. As a result, Chinese watercolour painting has developed a set of expressive techniques that highlight the cultural characteristics of the nation in terms of aesthetics, concepts and techniques, resulting in a painting style with a distinctive national personality at present. Although Chinese watercolour painting has taken on a variety of styles with the intervention of modern and contemporary art, realistic watercolour painting is still the mainstream. However, there are obvious differences between the "realism" of Chinese watercolour painting and the "realism" of Western watercolour painting in terms of expression. The most distinctive feature is the "imagery" language of expression, which is closely linked to the cultural heritage of Chinese tradition and is of great value for research. I interpret the aesthetics, composition, colour and brushwork of Chinese realistic watercolour painting from the perspective of traditional Chinese aesthetics in order to deepen the understanding of Chinese realistic watercolour painting and to provide a reference for the further development of the art of Chinese realistic watercolour painting.

Recently, Genetic Algorithm(GA), which is a stochastic direct search strategy that mimics the process of genetic evolution, is widely adapted into a search procedure for structural optimization. Contrast to traditional optimal design techniques which use design sensitivity analysis results, GA is very simple in their algorithms and there is no need of continuity of functions(or functionals) any more in GA. So, they can be easily applicable to wide area of design optimization problems. Also, owing to multi-point search procedure, they have higher porbability of convergence to global optimum compared to traditional techniques which take one-point search method. The methods consist of three genetics opera- tions named selection, crossover and mutation. In this study, a method of finding the omtimum size and topology of drilling machine is proposed by using the GA, For rapid converge to optimum, elitist survival model,roulette wheel selection with limited candidates, and multi-point shuffle cross-over method are adapted. And pseudo object function, which is the combined form of object function and penalty function, is used to include constraints into fitness function. GA shows good results of weight reducing effect and convergency in optimal design of drilling machine.

본 연구는 30~40대 여성의 패션 아이웨어 구매결정 요인을 분석하기 위해 신경망 분석 기법을 적용하여 전통적인 모수적 분석 기법과 비교하였다. 패션 분야에서 신경망 등 머신러닝 기법은 맞춤형 패션 추천시스템에 많이 적용되는데, 국내 연구사례는 아직 미흡하다. 본 연구는 2017년에 전통적 계량기법으로 수행된 연구를 신기술로 다시 분석하여, 양자를 비교함으로써 신경망 기법의 유용성을 확인하고자 한다. 본 연구는 L-BFGS-B 신경망을 하이퍼볼릭 탄젠트로 활성화 시킬 때, 소비자들이 선호하는 디자인형태에 대한 분류정확도가 86.2%로 가장 좋았다. 소비자의 직업과 새로운 스타일에 대한 추구가 가장 중요한 구매결정요인이었다. 한국의 선글라스 소비자들은 "안전한 변화"를 가장 선호하는 것으로 해석된다. 이런 분석 결과는 선글라스 프레임 및 렌즈에 있어서도 동일하게 나타난다. 전통적인 계량분석의 결과물은 소비자가 어떤 집단에 속하는지 여부에 따라 선호하는 선글라스의 종류가 다르다고 본다. 이에 비해 신경망분석의 결과물은 각 개인별로 선호하는 선글라스를 개인별로 예측해준다. 이것이 기여하는 바는 개인별 맞춤형 선글라스 추천 시스템을 개발할 수 있게 해준다.

한국화는 전통적으로 '종이' 를 바탕 재료로 사용해 왔으며, 그 종이 위에 먹이나 채색으로 작품을 제작하여 왔다. 그러한 전통이 오늘에까지 이어지고 있는 가운데 표현 방법이나 재료는 다양해지고 오늘날 시대에 부응하는 새로운 모색을 시도하고 있다. 한국화의 새로운 모색 가운데 표현 재료는 작품의 구조와 형식에 변화를 줄 수 있다. 이는 표현 재료가 작품에 있어서 중요한 위치를 차지하고 있음을 말한다. 현대 한국화에 있어서 재료적 측면의 모색 가운데 하나는 '한지' 에 대한 모색이다. 오늘날 '한지'는 바탕재료의 개념을 넘어 오브제로서 '한지' 그 자체를 작품으로 보기도 한다. 즉, '한지'라는 재료의 개념과 작품의 개념이 분리되는 것이 아니라, 재료 자체가 작품이 되는 것이다. 그러므로 '한지' 는 작가가 표현하고자 하는 것을 담아내는 '바탕 재료'적인 측면과 한지 그 자체가 작품화되는 '오브제'적인 두가지 측면을 동시에 지니고 있는 것이다. 본 연구에서는 '한지'가 지니고 있는 오브제의 성질에 주목하며, 한지의 오브제적 성질이 어떻게 '한국미'와 관계하면서 조형성으로 나타나고 있는지 현대 한국화를 통하여 살펴보고, 한지 오브제를 이용한 작가들의 작품들을 살펴보고 있다. 한국화에서 한지 오브제를 이용하는 표현은 1960년대 이응노 권영우 등에 의해 실험적 표현 방법으로 시작되었다. 그러나 1970년대와 1980년대 들어 소강상태를 보이다가 1990년 '한지작가협회' 가 출범하면서 한지 물성에 대한 관심이 표출되었다. 이때 한국화내에서도 한지의 물성에 대한 관심을 가지면서 임효 이기숙 원문자, ...최무영 등에 의해 본격적으로 이용되기 시작하였다. 이들은 대개 한지가 제품이 되기 전 닥죽(닥 섬유)의 상태에서 그 물성의 특성을 이용하여 작품의 재료로 끌어들이고 있다. 여기서 한지의 물성을 통한 오브제의 표현은 한국화의 조형실험으로서 잊혀진 우리의 전통 미술 재료를 발견하자는 것이며, 한지가 가지고 있는 한국 미의식의 발현이라는 점에 주목하고 있다. 즉, 우리의 미의식을 바탕으로 하여 이를 현대적인 조형정신으로 나아가게 하려는 데 큰 뜻이 있다는 것을 알 수 있다.

Traditional pile-buildings in Southeast Asia has high utility. Their floors are lifted above the ground to stave off humidity in the house, increase the amenity and hygienic condition, fend off fierce animals or harmful animals like rat, and protect the house from being submerged in flood waters. Such traditional pile-buildings have Austronesian saddle-backed roof commonly, and are built through various techniques such as joining and mortising, without use of nails. The roof has a considerably large proportional appearance, and for this formal characteristics, the roof is symbolized as boat on occasions. The roof has dual structures or is lifted in some cases to facilitate the ventilation, and the wall is formed to maximize the ventilation. This housing types the hierarchy of foundation, housing space, and roof, which implies religious symbolism that human is above animal and God is above human. However, housing types in Southeast Asia have very different detailed form and culture, depending on the ethnic and religious characteristics. As explained above, this study examines the common aspects and diversity based on the form and culture of traditional housing of Southeast Asia and provides useful basic academic data.

During the traditional production process of yugwa, a Korean traditional oil-puffed snack, three bacterial isolates, 12, 37, and B1 from waxy rice slurry were characterized by using the molecular techniques, and the quality of the yugwa prepared by using three isolates was examined in relation to physical and sensory properties. Isolates 37 and B1 were identified as Lactobacillus sp. by 16S rDNA sequence analysis, while isolate 12 was as Bacillus amyloliquefaciens by gyrA sequence analysis. Waxy rice inoculated with isolate 12 demonstrated the lowest hardness and the highest peak and [mal viscosity. Yugwa prepared from isolate 12-inoculated waxy rice indicated the lowest hardness and the highest volume expansion, the key characteristics of yugwa. This result presents the possibility for the use of a starter in the commercial production of yugwa and other rice-based snacks.
