This qualitative research provides a situation model, which is designed for promoting learning of eigenvalue and eigenvector. This study also demonstrates the usefulness of the model through a small groups discussion. Particularly, participants of the discussion were asked to decide the numbers of milk cows in order to make constant amounts of cheese production. Through such discussions, subjects understood the notion of eigenvalue and eigenvector. This study has following implications. First of all, the present research finds significance of situation model. A situation model is useful to promote learning of mathematical notions. Subjects learn the notion of eigenvalue and eigenvector through the situation model without difficulty. In addition, this research demonstrates potentials of small groups discussion. Learners participate in discussion more actively under small group debates. Such active interaction is necessary for situation model. Moreover, this study emphasizes the role of teachers by showing that patience and encouragement of teachers promote students' feeling of achievement. The role of teachers are also important in conveying a meaning of eigenvalue and eigenvector. Therefore, this study concludes that experience of learning the notion of eigenvalue and eigenvector thorough situation model is important for teachers in future.

Korea faces challenges from the recent development catch-up countries and the absence of catch up incentives. For Korea to solve the issue of post catch-up problems and create a new development path based on creative innovation, there is an urgent need to secure a system design capability for the production of creative knowledge and talent that can create a competitive society. However, the conservative inclination and a lack of a customer-oriented attitude of Korean universities and professors leads to a standardization of talent and a passive restructuring of the curriculum by universities instead of a direct correspondence with the demands of companies and society. The compatibility of Korean university education with the demands of society remains the lowest in the world and creative education in Korea faces a difficult situation. The world is transforming from a knowledge-based economy to a creativity-based economy and a competitive society will led by creativity, not by knowledge. The success of a country in nurturing creative talent will determine its future national competitiveness. For Korea to be become a global leader in the new era of creativity, it needs to make proactive preparations. It is imperative for Korea to transform the educational system from the previous cramming system to a creativity-nurturing system.

Aquaculture production of Korean rockfish Sebastes schlegeli has been continuously increased from 2000s and the fish has become the second most important mariculture fish in Korea. However, there are some environmental problems in aquaculture of Korean rockfish recently. In this regards, stress responses to high water temperature was examined via oxygen consumption, blood physiological parameter and endocrinological method. Oxygen consumption of Korean rockfish had significantly increased with rising water temperature. And oxygen consumption during the light time was no different with the dark time. The levels of aspartate aminotransferase (AST) and alanine aminotransferase (ALT) showed no difference until $27^{\circ}C$, but it had rapidly increased at $30^{\circ}C$. Moreover high water temperature affected to increase in plasma glucose and cortisol levels.

As a dental technician, the aim of the present study on maxillofacial prosthesis was to research its relation with dental technology and further development aspects by looking into its history, kinds, production materials and process. Dental technicians are to expect a great potential to work as maxillofacial prosthetist if having an interest in education of maxillofacial prosthesis field, and developing and operating the education process by expanding the range of dental technology. This article is to present overall history of maxillofacial prosthesis and some background information on the materials which have been used from the past. The maxillofacial field plays essential functions of mastication and speech, as well as performs appearance, which evokes good or bad feelings as an instant and instinctive response. The use of maxillofacial prostheses is not merely the replacement of a missing part of the face, resulted from injuries, but a rehabilitation process to help individuals come back to society. Rehabilitation includes both patient's physical and psychological recovery, such as self-esteem and selfconfidence. There has been a rapid development in application potentials of maxillofacial prosthesis technology which include implant, which can penetrate skin, and new materials. In order to produce maxillofacial prosthesis, general procedures of maxillofacial laboratory work should be understood first. Maxillofacial prosthesis and the dental prosthesis have many similarities in its academic perspective and originality. Maxillofacial prosthesis should be added into the curriculum for dental technology to achieve co-enhancement of the two fields.

Objectives: This study was to examine the independent and mediating effect of socioeconomic position and social relationship on depression. Methods: The study analyzed the data from the 2014 Korea Welfare Panel Study(n=9,172) using descriptive statistics, Kendall's rank correlation analysis, multiple regression analysis and the Sobel test. Results: Much of the connection between parental socioeconomic position and respondent depression was explained by respondent educational attainment in men but was not in women. A large portion of the association between educational attainment and depression was explained by type of household and satisfaction with social relationship among men. The effect of educational attainment on depression was fully mediated by type of household among women. The effect of type of household on depression was partly mediated by satisfaction with social relationship in men and women. Lastly, educational attainment, type of household and satisfaction with social relationship had an independent association with depression among men, but educational attainment was not statistically significant among women. Conclusions: Our study illuminated the importance of the independent and mediating effect of parental and respondent socioeconomic position and social relationship in the production of depression for South Korean adults.

Biological evaluation of residual malathion after 168 hrs of single dipping exposure of White Leghorn hens to different concentrations (0, 0.5, 1.0 and 1.5%) of pesticides was investigated. Thirty-two male albino rats divided into four groups of eight each were kept on 20% isoproteinous diet prepared from the meat of these malathion dipped hens. After 30 days feeding trial, the rats were killed by decapitation. No significant change was found in erythrocytes. However, the triglyceride concentration in brain tissue was increased significantly (p<0.05) when dose level of pesticide was 1% in dipping solution. Similarly, malathion exposed poultry meat failed in altering any significant change in the pancreatic amylase and lipase activities of rats. This study concludes the virtual absence of toxic accumulation of pesticide in the meat of birds after 168 hrs of exposure in usual concentration range upto 1.5%.

The genetic diversity of native chicken populations from Myanmar, Thailand, and Laos was examined by using 102 insertion and/or deletion (indels) markers. Most of the indels loci were polymorphic (71% to 96%), and the genetic variability was similar in all populations. The average observed heterozygosities ($H_O$) and expected heterozygosities ($H_E$) ranged from 0.205 to 0.263 and 0.239 to 0.381, respectively. The coefficients of genetic differentiation (Gst) for all cumulated populations was 0.125, and the Thai native chickens showed higher Gst (0.088) than Myanmar (0.041) and Laotian (0.024) populations. The pairwise Fst distances ranged from 0.144 to 0.308 among populations. A neighbor-joining (NJ) tree, using Nei's genetic distance, revealed that Thai and Laotian native chicken populations were genetically close, while Myanmar native chickens were distant from the others. The native chickens from these three countries were thought to be descended from three different origins (K = 3) from STRUCTURE analysis. Genetic admixture was observed in Thai and Laotian native chickens, while admixture was absent in Myanmar native chickens.

Fabrea salina is a hypersaline ciliate having importance as a live food source for juvenile stages of aquatic animals including smaller invertebrates. The analysis of this ciliate for proximate and biochemical composition was carried out. The moisture, protein, fat, carbohydrate and ash content of F. salina from natural sources were 86.66$\pm$0.380, 56.66$\pm$0.494%, 36.66$\pm$0.614%, 1$\pm$0.073% and 4$\pm$0.182%, respectively. Gas chromatographic analysis (percent area below the curve) revealed that the presence of oleic acid was higher over other fatty acids in both natural and cultured F. salina. The absolute content of oleic acid was higher in natural (18.91% area) than in the cultured (10.74% area) F. salina. Linoleic and linolenic acids were also among major fatty acids with the percentage area of 16.29 and 14.58, respectively. The number of fatty acids in cultured Fabrea was less as compared to the natural ones and the oleic acid was followed by palmitic acid, palmitoleic acid, linoleic acid and stearic acid.
