The purpose of this study was to analyse the principles and methods of Taegyo-Singi with regard to emotion and to review basic informations on Taegyo programs for promoting prenatal development. Taegyo-Singi was analyzed as follows. First, the contents of Taegyo-Singi were classified into principles and methods of Taegyo. Second, the domains of emotion were categorized into emotional perception, emotional expression, emotional understanding, and emotional regulation based on the classification of Mayer and Salovey, and Moon. Third, the contents of Taegyo-Singi were classified into the four domains of emotion. Finally, the reliability and validity of the classification were obtained through inter-rater agreement and analysis of content validity. The results indicated that first, the principles of Taegyo presuppose parental influence on temperament formation, and that the emotional states of the mother in the prenatal and prepregnancy period is the most influential variable in a child's temperament formation. Second, the methods of Taegyo presuppose that the human mind interacts with their behavior. Therefore, through emotional support of family members, 'jon-sim (the serene mind)' and 'chung-sim (the mind from rectitude)' are the key methods of Taegyo. This means that the Korean tradition of Taegyo focused on the emotional domain of development, especially emotional regulation. This coincides with the emotion-focused temperament theory that individual differences in temperament reflect individual differences in emotion.

When the speed of a coaxial rotor helicopter in forward flight increases, the wake skew angle of the rotor increases and consequently the position of the vena contracta of the upper rotor with respect to the lower rotor changes. Considering ambient air and the effect of the upper rotor, this study proposes a nonuniform inflow model for the lower rotor of a coaxial rotor helicopter in forward flight. The total required power of the coaxial rotor system was compared against Dingeldein's experimental data, and the results of the proposed model were well matched. A plant model was also developed from first principles for flight simulation, unknown parameter estimation and control analysis. The coaxial rotor helicopter used for this study was manufactured for surveillance and reconnaissance and does not have any stabilizer bar. Therefore, a feedback controller was included during flight test and parameter estimation to overcome unstable situations. Predicted responses of parameter estimation and validation show good agreement with experimental data. Therefore, the methodology described in this paper can be used to develop numerical plant model, study non-uniform inflow model, conduct performance analysis and parameter estimation of coaxial rotor as well as other rotorcrafts in forward flight.

Transition metal dichalcogenides (TMDs) such as $MoS_2$ is the thinnest semiconductor, exhibits promising prospects in the applications of optoelectronics, catalysis and hydrogen storage devices. Uniform and high quality $MoS_2$ is highly desirable in large area for its applications on commercial scale and fundamental research. Many experimental techniques i.e CVD have been developed to successfully synthesis $MoS_2$ on large scale, here in this work atomistic detail to understand the growth mechanism is addressed which was greatly overlooked. Here based on first principles calculation we found that polarity of seeding promter (crystal violet considerd in this work) controls the growth mechanism. It is also found that molybdenum destroys the precursor while sulfur adsorption with precursor is favorable.

The effects on the ferromagnetism of the O or Zn defect in Cu-doped ZnO with the concentration of 2.77-8.33% have been investigated by the first-principles calculations. The Cu doping in ZnO was calculated to be a kind of p-type ferromagnetic half-metals. When the Zn vacancy exists in Cu-doped ZnO, the Cu magnetic moment increases, while for the O vacancy it is reduced. It is noticeable that the ferromagnetic state was originated from the hybridized O(2p)-Cu(3d)-O(2p) chain formed through the p-d coupling. The carrier-mediated ferromagnetism by nitrogen or fluorine does not depend on their concentration.

In the world, the old population is growing fast and many countries went into an advanced age society. Therefore the development of everyday products, electric appliances, and welfare services considering old people is more important than ever. In particular, the complexity of products can cause many problems for old people. Universal design is an approach to create environments and products that recognizes the diversity of users, regardless of their ability or age. Universality evaluation for a product is very important to verify old people's accessibility and usability for the product. Universality means how good a product was designed in view of universal design principles. In this study, UNIX, a method to evaluate the universality of a product was developed. UNIX was based on seven universal design principles; equitable use, flexibility in use, simple and intuitive, perceptible information, tolerance for error, low physical effort, size and space for approach and use. UNIX is a kind of expert evaluation and very simple method. The method is consisted of two steps. In the first step, relative weights for seven principles and subjective ratings on design suitability for each principle are obtained. In the second step, universality index (UNIX) of each product is obtained by weighted average multiplying relative weights and rating scores. As a case study, this method was applied for mouse designs. In conclusion, this method could be effectively applied to evaluate the universality of a product.

Although subway system continues to be the backbone of transportation systems in a city like Seoul, there will still be areas across the city where subway services are not avaliable. Interest has steadily grown to fill this missing routes in overall urban transportation system. Light Rail Transit (L.R.T) system has been recently thought to be an appropriate mode of transportation by businessmen, professionals and transportation industry. In this regards, the purpose of this study is to explore whether L.R.T can be a feasible form of urban rail mode in the context of Seoul. First, the study develops the mathematical models to derive optimum route networks and stations. Integer Programming is employed to determine whether alternative routes are financially viable from the viewpoint of revenue maximization principles. Second, mathematical models developed are applied to Yoido area in order to examine the validity of model structures. The models constructed turns out be capable of handling alternative routes and stations. Application of models are successfully carried out to derive financially feasible set of routes and stations.

When teaching traditional pattern-themed textile design, it has been found that many students struggle during the investigation stage of traditional patterns and complete the development of patterns in relatively simple layout methods, such as block patterns and half drop patterns. Until now, digital textile design textbooks lack content on how to develop patterns. Judging that the current teaching method leads to difficulties in developing a new sense of textile design, this study focused on Heesch-tiling tessellation and software called TESS, a program that can transform patterns themselves. This study is an academic study on the methodology of first developing patterns through TESS, a tessellation program developed for elementary school students in the U.S., and then applying various lines and colors to the complete patterns and textures using Adobe Illustrator. In this study, the concept, formative characteristics, and generative principles of Heesch-tiling tessellation were examined, and the process of developing new patterns using the TESS program, which can be used to create patterns through Heesch-tiling principles, was intended to help in textile design education. Therefore, after analyzing the comprehensive concepts and principles of tessellation, the next step is to understand the principles and the characteristics of pattern making only for Heesch-tiling tessellation, and then ultimately to develop new patterns. While patterns using traditional tessellation layouts have been characterized mainly by repeated geometric shapes, Heesch-tiling tessellation can express surrealistic attributes, such as those by painter M. C. Escher or style elements such as those in neo-pop.

This study tries to analyze the influence of IIT's educational system on the Jong Soung Kimm's Architecture. Architect Kimm was the first student in Korea who gained admission to the IIT and was directly learned from Mies van der Rohe. At IIT, he completed a university course from 1956 to 1961, and finished a degree of master under the direction of Professor Myron Goldsmith in 1964. After the graduation, he entered Mies's office and became the professeur of IIT from 1966 to 1978. In consideration with these facts, it is no exaggeration to say that Kimm's architecture was formed by the IIT's educational system and Mies's architectural principles. According to the synopsis of the 5-year curriculum 1944-45, the object of architectural work in IIT is the clarification of : 1)the structure as an architectural factor, its possibilities and limitations 2) space as an architectural problem 3) proportion as a means of architectural expression 4) the expression value of materials 5) the application of these principles by means of free creative work. Architect Kimm's works designed in Korea reflect well these objectives. But Kimm also knew well the problems of IIT's educational system. After the retirement of Mies, IIT's educational system had the tendency to overstress the technology of structure and simplify the complexity of Miesian architectural principles. In opposition to this tendency, architect Kimm continued to keep the spacial and formal subtlety which possess the Mies' original architecture. This shows very well the future direction of Kimm's architectural activities.
