In this paper, a forearm Mechanism design inspired by ligamentous structure of the human body is proposed. The proposed mechanism consists of four rigid bodies and fourteen wires without any mechanical joints. Actually, the mechanism is based on the concept of the tensegrity structure. Therefore, the proposed mechanism has inherently compliant characteristics due to the flexibility of the wires composing the structure. Rigid bodies and wires of the mechanism mimic bones and major ligaments in the forearm of the human. The proposed mechanism is classified as one of the interconnected hybrid flexure systems. The analysis method of the degree of freedom (DOF) of the proposed mechanism is also introduced through analyzing technique of the interconnected hybrid flexure systems, in this paper. Ultimately, the proposed mechanism, whose structure is complicated with rigid bodies and wires, mathematically drives that it has 3-DOFs.

Affective quality is considered one of the most influential factors for the competitive power of consumer products. Since the human affective response is very abstract and comprehensive, it is very difficult to understand and manipulate the Affective Quality in scientific method. This study suggested the three-level hierarchical structure of the human affection according to the human affective response process, and subdivided the Affective Quality into three subordinate concepts such as 'Organoleptic Quality', 'Affective Quality Factor' and 'Overall Affective Quality.' Also the categories of adjectives which used to express the human affections for the three levels of affective structure were suggested. The results of this study could be used as a frame of systematic approach method to the Affective Quality.

This study tried to search for solutions of present problems in architecture through interdisciplinary study which includes biology, literature, aesthetics, and psychology, and set up two models composed of the nature and the human perception which contemporary architecture has problems on. By nature-oriented approach through biology and romanticist literature, the five types of organic principles which could be obtained from structure and order in natural system and by human perception-oriented approach through aesthetic theory of Harold Osborne and perceptual and cognitive psychology the structure and order of perceptual arousal, perceptual balance, and perceptual order in human cognition based on perceptual appropriateness could be found. The unified and organic framework of architectural composition must be considered through a deductive and inductive study as this study was approached. The results of the present study can be applied to construct human-oriented design principles and factors in architectural space and form, and better environmental quality.

The purpose of this study was to introduce the concept of social capital to the studies of human ecology in Korea. Social capital theory provides a framework for analyzing well being of families because the concept of social capital can be understood as an important family resource, including social networks, social supports, and family structure. The utilization of the social capital theory, considering both positive and negative effects on equality, in the studies of human ecology is expected to contribute to the social understanding of the characteristics of households as a system that are related with environments, and provide a basic theoretical framework for discussing family structure, human capital development, poverty, and healthy families.

The purpose of this study was to identify remained real state of groves of enclosed village in human settlement circle. That was practiced in case of Chinan-Gun region which traditional elements had well been conservated. 48 village groves were found by site survey, reference and interview in Chinan-Gun region. 27 groves of 48 village groves were clarified as complementing village grove by classification of grove character. It was identified through survey that many were partially destructed by development and human use. The results of this study showed general, socio-behavioral characteristics, characteristics of forest state and vegetation structure of complementing village groves. Length, area, form, type, motive, location, relationship of those were analyzed to identify general characteristics. Facilities, human behavior and ownership of those were analyzed to identify socio-behavoral characteristics. Dominent species, appearing rate, height, width, density and biodiversity of upper trees were analyzed to identify forest state and vegetation structure. Interrelation of each factor were analiged and comparative review with previous studies was achieved.

This study has resulted in the followings applying costume's form and meaning to the theory of structuralism established by Saussure and the extensive and contained meanings of Roland Barthes. The kinds of woman's costume of the Romanesque era were not various, but those of the royal family and aristocratic class were more various and decorated better than the lowly persons. So their social levels could be differed by the forms of the costume they wore. Each form of costume was differed according to the structural elements and showed the feature that the form is the costume of the era and social position's differences of the wearers' sexes, levels, and vocations in the same era. Costume's analistic body was the costume's form selected according to the central analystic elements, this showed the meaning of the era's levels and classes, that is, the costume's structure was reflected by the era's features. In the structure of the woman's costume in the Romanesque era, many religious features were emphasized and the elements forming each analystic body were classified and meant the society's features.

The research investigates the inhibition of fatty acid biosynthesis of the human Acetyl-CoA Carboxylase enzyme by the aromatic-structure inhibitors (also known as ligands) containing variables of substituents, contributing an important role in the treatment of fatty-acid metabolic syndrome expressed by the group of cardiovascular risk factors increasing the incidence of coronary heart disease and type-2 diabetes. The effective interoperability between ligand and enzyme is characterized by a 50% concentration of enzyme inhibitor ($IC_{50}$) which was determined by experiment, and the factor of geometry structure of the ligands which are modeled by quantum mechanical methods using HyperChem 8.0.10 and Gaussian 09W softwares, combining with the calculation of quantum chemical and chemico-physical structural parameters using HyperChem 8.0.10 and Padel Descriptor 2.21 softwares. The result data are processed with the combination of classical statistical methods and modern bioinformatics methods using the statistical softwares of Department of Pharmaceutical Technology - Jadavpur University - India and R v3.3.1 software in order to accomplish a model of the quantitative structure - activity relationship between aromatic-structure ligands inhibiting fatty acid biosynthesis of the human Acetyl-CoA Carboxylase.

Bag of visual words is a popular model in human action recognition, but usually suffers from loss of spatial and temporal configuration information of local features, and large quantization error in its feature coding procedure. In this paper, to overcome the two deficiencies, we combine sparse coding with spatio-temporal pyramid for human action recognition, and regard this method as the baseline. More importantly, which is also the focus of this paper, we find that there is a hierarchical structure in feature vector constructed by the baseline method. To exploit the hierarchical structure information for better recognition accuracy, we propose a tree regularized classifier to convey the hierarchical structure information. The main contributions of this paper can be summarized as: first, we introduce a tree regularized classifier to encode the hierarchical structure information in feature vector for human action recognition. Second, we present an optimization algorithm to learn the parameters of the proposed classifier. Third, the performance of the proposed classifier is evaluated on YouTube, Hollywood2, and UCF50 datasets, the experimental results show that the proposed tree regularized classifier obtains better performance than SVM and other popular classifiers, and achieves promising results on the three datasets.

4차 산업혁명시대의 도래로 인해 현대사회는 과거와 다르게 경제, 경영, 문화 등 다양한 요소들이 변화하고 있다. 그 중 경영적 측면에서 나타나는 주된 특징은 유형재화 중심에서 무형재화 중심으로 변화하는 것이며 이에 기업들은 새로운 경영방식 도입, 제조에서 서비스로의 전환, 기술의 확장 등 혁신을 추구하기 위해 노력 하고 있다. 하지만 변화하는 시대 지속적 가치창출을 위해 가장 중요성이 높아지고 있는 인적자원에 관해서는 아직까지 단순한 방식의 전환에 머무르고 있어 실질적인 혁신을 가능케 하는 노력이 부족한 실정이다. 이에 본 연구에서는 서비스경제시대 새로운 인재상에 대한 기업에서의 활용성을 검증하고자 인재요소에 대한 중요성을 인식하고 기존 도출 된 서비스경제시대에 변화된 인재상 요소들이 조직문화와 조직구조의 유형에 따라 어떠한 관계와 차이가 있는지를 연구하였다. 최근 연구에서 도출, 검증 된 서비스경제시대 인재상요소를 활용하여 구성원들의 생각과 행동에 영향을 주는 요소인 조직문화와 조직구조의 유형으로 나누어 관계를 검증하였으며 그 결과 조직문화와 조직유형별로 유의미한 인재상에 다소 차이가 있었으나 두 가지 요소를 결합하여 해석하였을 경우에는 새로운 인재상이 모두 유의미한 것으로 나타났으며 이는 서비스경제시대 인재상이 실제 기업에 적합하다는 것으로 해석될 수 있다. 다만 본 연구의 지표가 한정적 이었다는 한계를 극복하기 위해 향후 다양한 요인들이 고려 된 표본과 체계화 된 조직유형 및 업종별 산업별 분류를 통한 연구가 지속적으로 이어져야 할 필요가 있다.
