ZnO is a promising material for UV or blue LEDs p-Type ZnO thin films which are imperative for the p-n junction of LEDs are difficult to achieve because of strong compensation of intrinsic defects such as zinc interstitial and oxygen vacancy. The method of codoping group three elements and group five elements is effective for the realization of p-type ZnO films. In this study, We codoped N and Al m ZnO thin films by RF magnetron sputtering and annealed the films in sputtering chamber. Some films showed p-type conductivity m Seeback effect measurement.

The study was executed for development of sensing elements of electronic tongue which could discriminate taste of liquid and semi-liquid foods. Five polymeric membranes which were composed of polymer, plasticizer, electro-active materials were prepared. After each polymeric membranes were mounted in an electrode body, membrane potentials due to electrochemical reaction with taste stimuli were measured. The experimental results were interpreted in view of the membrane's non-selective responses to stimuli.

This study presents an effective method for additional recovery of residual actinides in liquid electrodes after the electrowinning process of pyroprocessing. The major distinctive feature of this method is a reactor with multiple reaction cells separated by partition walls in order to improve the recovery yield, thereby using the interelement difference in diffusion coefficients within the liquid electrode and controlling the selectivity and purity of element recovery. Through an example of numerical simulation of the diffusion scenarios of individual elements, we verified that the proposed method could effectively separate the actinides (U and Pu) and rare-earth elements contained in liquid cadmium. We performed a five-step consecutive recovery process using a simplified conceptual reaction cell and recovered 58% of the initial amount of actinides (U + Pu) in high purity (${\geq}99%$).

In the Nei Ching. the interrelation of Yin and Yang within the human body. based upon a perfect balance and a perfect mutual control. The affinity of Yin and Yang to each other was held to have a decisive influence upon man's health. Perfect harmony between the two primogenial elements meant health. Disharmony or undue preponderance of one element brought disease and death. The interrelation of Yin and Yang in the Nei Ching, had the organic view of the life. The world view of the harmony and balance in Nei Ching shows a unified world view that is symmetrical and in equibrilium in unity and conflict of opposite elements instead of combining with the closely related elements, namely, it is a fact that the life principle of the theory of Yin and Yang in Nei Ching is not the object of the killing and destroying for unity and conflict of opposite elements but the life cycle and life rule for the purpose of achieving the world of harmony, coexistence, and engendering via check and balance as well as confrontation between the opposite elements. In Nei Ching, like this, in the case where all of the antagonistic elements including the antagonism between You and Me, Yin and Yang affirm and tolerate each other, the organic view of the life in which the life of You and Me and the macrocosm is able to be maintained is suggested to the human being at a whole crisis.

Objectives : To define an everyday ethics for students and doctors of Korean Medicine, people who desire treatment, cultivation and healing through Korean Medical means by determining its conditions and characteristics. Ways of constructing its contents fit for contemporary society were discussed. Methods The threefold Heaven-Earth-Human theory, Yinyang theory, circulation of the Five Phases along with contents of classics such as 『Huangdineijing(黃帝內經)』, 『Guanzi(管子)』, 『Zhongyong(中庸)』, 『Daxue(大學)』, 『Beijiqianjinyaofang(備急千金要方)』, 『Donguibogam(東醫寶鑑)』 were newly interpreted or quoted for explanation. Results : The elements that construct natural ethics and Natural Ethics were established as following: the natural perspective of Nature and People, natural sustainability as fundamental principle, co-existence and initiative circulation as fundamental rules, education and cultivation of lay people, and professional character and competence. Conclusions : The authors suggest a reconstruction of the inherent philosophy, ethics, principle, rule, life guidelines of Korean Medicine within the framework of "natural ethics" and "Natural Ethics" as a prior task for better integration of traditional KM into contemporary society.

This study focuses on fashion adoption behavior of adolescents. The impact of their clothing involvement factors and socio-demographic factors on their fashion adoption behavior was examined. Three core issues were identified for empirical test: 1) Elements of clothing involvement for adolescents; 2) Fashion adoption behavior of adolescents; 3) Impact of clothing involvement elements on fashion adoption behavior. The Likert Type questionnaires were used to measure clothing involvement and fashion adoption behavior. The data of 472 samples drawn from middle and high school students in Taegu Metropolitan City were analyzed by factor analysis, ANOVA, Scheff test, t-test and regression analysis. Main results of the study are as follows. 1 . Concept of the clothing involvement is composed of five dimensions: importance, fashion, self-expression, pleasure, and buying risk. 2. Socio-demographic factors do influence fashion adoption behavior. Average monthly pocket money, expenditures on clothes and household income are found to have statistically significant impacts on the adoption behavior. Female students are more fashion-oriented than male students. 3. The clothing involvement elements are found to have significant influences on fashion adoption behavior: fashion, importance and self-expression elements on fashion innovation; fashion, importance and pleasure elements on fashion information search.

The high school students' problem solving patterns and their features in scientific inquiry, especially on controlling variables and stating hypothesis have been investigated. The 8 problems on controlling variables and stating hypothesis were selected out of the scientific inquiry area in the experimental tryout of Aptitude Assessment for College Education, and had been used to find the patterns and their features. The results of findings are as follows: There were seven patterns in the process of solving problems. Five of seven patterns were found in right answers and four patterns in wrong answers. Two patterns were found in both right and wrong answers. Some students could solve the problems even though they did not understand the elements of the scientific inquiry, controlling variables and stating hypothesis. The false application of physics concepts, misunderstanding about the elements of the scientific inquiry and using unrelated experience and conjectures were the features of students' wrong answers. On the other hand, the right application of physics concepts, understanding and applying the elements right, infering answers from the tables and figures on statements of suggested problems were the features of right answers. The further studies on this kind may helpful to find the higher mental abilities related to scientific inquiry and to develop tools for testing students' scientific inquiry thinking skills.

Due to the expansion of cities and the increasing number of large-scale and complex public spaces, there is an increase in public signage. Moreover, the information described on these signs tends to be diverse and complicated. Complex signs that contain multiple destinations or other information must be considered to determine not only the proper size, color, etc. but also the most effective arrangement of design elements. In the previous research, the cognitive utility of complex public signs was estimated using computer simulation software. In the current research, we focused on the objective estimation of the effectiveness of the results obtained in the previous research utilizing an eye mark recording system. Two cognitive engineering experiments clarified five points for improvement in the usability of complex signs, as follows: 1) Parallel construction of characters and pictograms is more efficient. 2) Grouping elements result in rapid recognition of information chunks. 3) Visual characters and pictograms are effective, along with proper density of information. 4) Specific arrangement of sign arrows is effective. 5) Figures on signs influence the sequence of information searches.
