Industrial ceramic of Korean industrial design, especially tableware show different characteristics in their forms between 1940s-1960s, and 1970s-1990s. The shift of such changes can be verified objectively by module measurement. The validity of the results applying this method is supported by the investigation of the change of aesthetic modes in Korean society. The most obvious change in the figurative characteristics of tableware is in the outline of their external shapes. 'Module' is used to describe and analyze the changes of such an external shape more strictly as the objective method and measuring the module is employed. This method was developed by the combination of the method analyzing figurative art works by Re Corbuise who uses 'module' with Hambidge's method to describe and analyze the works by means of the golden section. The shift of flgurative changes of tableware could be examined objectively and elaborately by such a newly developed method. The industrialization of tableware production in Korea was begun in 1940s. Then its design was not activated, but as the society has been stabilized through the liberation and civil war, design was settled in 1960s. After that, the design has played the essential roles in 1970s. And as the importance of design in producing goods has been recognized according to the economic growth. The design of tableware shows a remarkable difference based on 1960s and 1970s in such an economic growth. It is resulted from the scientific data analysis of the design since 1940 without any preference. According to the results which analyze the external shapes of tableware for last 50 years, the tableware designs show much differences between 1940s-1960s, and 1970s-1990s. The figurative changes of Korean tableware show the similar trends to the transitional aspects of the society. Design is the manifestation of aesthetic modes which have been developed in a close relationship to society and especially economy. In Korea the development of design was initiated by the economic growth and the Korean aesthetic modes were also changed with the economic growth. The transitional shift of aesthetic modes shown in the figurative characteristics of tableware which are divided on the basis of 1960s and 1970s was peak in 1970s with the development of economy and design started in 1960s.

The purpose of this study was to examine the mediating effects of mattering and unconditional self-acceptance in the relationship between college student socially-prescribed perfectionism and social anxiety. For this purpose, a questionnaire was conducted for students in college and a total of 408 copies were used for analysis. The instruments used in the measurement were socially prescribed perfectionism scale(HFMPS), social anxiety scale, mattering scale, and unconditional self-acceptance. The collected data were analyzed by descriptive statistics and correlation analysis using SPSS 21.0, and the structural equation model and mediating effects were verified using Mplus 7.0. The results of the study are as follows. First socially-prescribed perfectionism showed a positive correlation with social anxiety but negative correlation with mattering and unconditional self-acceptance. And there was a positive correlation between mattering and unconditional self-acceptance but negative correlation with social anxiety. Second, the mediating effect of mattering was confirmed in the relationship between socially-prescribed perfectionism and social anxiety. Third, the mediating effect of unconditional self-acceptance was confirmed in the relationship between socially-prescribed perfectionism and social anxiety. Fourth, the effect of double mediation of mattering and unconditional self-acceptance was confirmed in relation to socially-prescribed perfectionism and social anxiety in college students. Based on these findings, the implications of the study were presented and the limitations of the study and suggestions for further research were discussed.

In 2005, the Korean government decided to postpone the introduction of competition up to 2009 in the power plant service industry. Thus, the purpose of this study is to analyze the efficiency changes and the determinants of international competitiveness of Korean power plant service industry by the comparison between before and after 2006. The sample used in the estimation of efficiency is six firms III Korean power plant service sector for the period of 2003~2008. According to the results, technical efficiency before 2006 (2003~2005) is 0.865 and that after 2005 (2006~2008) is 0.947, which implies that efficiency has been improved after the delay of introduction of competition. In addition, according to the analyses based on the diamond model of Porter using survey data, demand condition has been ranked first in the determinants of international competitiveness. The second and the third important conditions are government and input factor ones. Firm's strategy/structure/competitiveness condition is the most weak condition. Therefore, it would be necessary for firms to improve this condition for competitiveness.

The distillation rate on LiCl-KCl eutectic salt under different vacuums from 0.5-50 mmHg was first investigated by using both a non-isothermal and a isothermal thermogravimetric (TG) analysis. Based on the non-isothermal TG data, distillation rate equations as a function of the temperature could be derived. Calculated flux by these model flux equations was in agreement with the distillation rate obtained from isothermal TG analysis. A distillation rate of $10^{-4}-10^{-5}$ mole $cm^{-2}sec^{-1}$ is obtainable at temperatures less than 1300K and vacuums of 0.5-50 mmHg. About a 99% salt distillation efficiency was obtained after an hour at a temperature above 1150 K under 50 mmHg in a small scale distillation test system. An increase in the vaporizing surface area is relatively effective for removing residual salt in the remaining particles, when compared to that for the vaporizing time. Over 99.95% of total distillation efficiency was obtained for a 1-h distillation operation by increasing the inner surface area from $4.52cm^2$ to $12.56cm^2$.

Molten salt electrorefining process achieves uranium deposits at cathode using an electrochemical processing of spent nuclear fuel. In order to recover pure uranium from cathode deposit containing about 30wt% salt, the adhered salt should be removed by cathode process (CP). The CP has been regarded as one of the bottle-neck of the pyroprocess as the large amount of uranium is treated in this step and the operation parameters are crucial to determine the final purity of the product. Currently, related research activities are mainly based on experiments consequently it is hard to observe processing variables such as temperature, pressure and salt gas behavior during the operation of the cathode process. Hence, in this study operation procedure of cathode process is numerically described by using appropriate mathematical model. The key parameters of this research are the amount of evaporation at the distillation part, diffusion coefficient of gas phase salt in cathode processor and phase change rate at condensation part. Each of these conditions were composed by Hertz-Langmuir equation, Chapman-Enskog theory, and interphase mass flow application in ANSYS-CFX. And physical properties of salt were taken from the data base in HSC Chemistry. In this study, calculation results on the salt gas behavior and optimal operating condition are discussed. The numerical analysis results could be used to closely understand the physical phenomenon during CP and for further scale up to commercial level.

The purpose of this study is to develop a technology for estimating rice growth and damage effect according to bacterial leaf blight using UAV multi-spectral imagery. For this purpose, we analyzed the change of aerial images, rice growth factors (plant height, dry weight, LAI) and disease effects according to disease occurrence by using UAV images for 3 rice varieties (Milyang23, Sindongjin-byeo, Saenuri-byeo) from 2017 to 2018. The correlation between vegetation index and rice growth factor during vegetative growth period showed a high value of 0.9 or higher each year. As a result of applying the growth estimation model built in 2017 to 2018, the plant height of Milyang23 showed good error withing 10%. However, it is considered that studies to improve the accuracy of other items are needed. Fixed wing unmanned aerial photographs were also possible to estimate the damage area after 2 to 4 weeks from inoculation. Although sensing data in the multi-spectral (Blue, Green, Red, NIR) band have limitations in early diagnosis of rice disease, for rice varieties such as Milyang23 and Sindongjin-byeo, it was possible to construct the equation of infected leaf area ratio and rice yield estimation using UAV imagery in early and mid-September with high correlation coefficient of 0.8 to 0.9. The results of this study are expected to be useful for farming and policy support related to estimating rice growth, rice plant disease and yield change based on UAV images.

In this study, we reviewed and analyzed the influencing factors of technology transfer performance in the previous studies (52 domestic journals and theses) and classified the various influencing factors into 6 top factors and 13 sub-factors based on the theoretical background. The study results of previous articles were analyzed by meta-analysis method so as to calculate the overall average effect size of influencing factors of technology transfer performance. As the result, the overall effect size (ESr) calculated through meta-analysis applying random effect model is .269, which corresponds to the medium effect size. By comparing effect sizes of influencing factors, the four(4) key influencing factors were also identified, which are 'number of researchers', 'dedicated organization', 'possess technology', and 'external cooperation'. The technology transfer performance are divided into three types: the number of technology transfers, technology transfer income, and other technology transfer performances. The major influencing factors of each type are derived through meta-analysis at the sub-category level. As moderator variables, the paper type and the data type were analyzed but no significant results were obtained. Since this research is limited to the technology transfer, it is necessary to carry out the study related to the influencing factors on the technology commercialization as following study.

If the real estate auction market indicators are relevant and meaningful, they can be meaningful information to the real estate market in connection with general real estate. The purpose of this study is to examine whether time-supply logic is applied in auction market by identifying time series correlations for the number of auctions, the auction rate, and the auction price rate, which are major indicators of real estate auction market. The real estate types were classified into three categories: residential real estate, land, and commercial real estate. The monthly time series of auctions in the metropolitan real estate were compiled for 96 months. Based on this data, the auction market model for each type was established and the mutual influences between the indicators were analyzed. As a result, the supply and demand indicators, the number of auctions and the auction rate, showed the nature of supply and demand according to the supply and demand logic of the market. However, the correlation was high for residential real estate and relatively low for commercial real estate. the auction rate has a long-term impact on price indicators, especially residential real estate, which is quantitatively explanatory and significant. The three auction-related indicators differ in degree, but there is a correlation, especially for residential real estate, which can be useful information for policy making.

The primary objectives of this study are twofold. One is to examine the psychometric properties of Family Empowerment Scale(FES) developed by Koren, DeChillo and Frisen(1992). The other is to develope a short-form FES. Data collected from 337 members of Parents' Solidarity of Children with Disabilities were used. FES had good internal consistency, but the results of confirmatory factor analysis(CFA) did not support the theoretical factor structure of the scale. Basic analyses such as correlation and descriptive analysis were performed to examine the characteristics of individual items and identify the limitation of the orignal FES. In addition, a series of CFA were carried out to develop a short-form FES. Finally 15 items were selected based on theoretical rationale and the results of CFA. Cronbach's ${\alpha}$ and the model fit indices for the short-form FES indicated that this measure has good construct validity as well as internal consistency. In discussion, usefulness and potential contribution of this study were explored in relation to content development in the area of measuring instruments.

Purpose - Previous studies have not paid attention to global self-corporate brand congruity and affective approach from the viewpoint of global self. This study explored an inducement of gratitude that, under the circumstance of corporate association, consumers feel toward corporate's responsible activities, pride related to corporate's ability, and global self congruity. Current researches also have examined positive behavior effects of global self-corporate brand congruity and the feelings on corporate products. Research design, data, and methodology - This research theoretically reviewed that corporate ability and social responsibility association would influence global self-corporate brand congruity, that corporate ability association could induce consumers' sense of pride, and that social responsibility association might induce gratitude. This study, furthermore, examined theoretically whether global self-corporate brand congruity, pride and gratitude could make consumers behave positively toward corporate products, and developed hypotheses. For the empirical analysis with the questionnaires, 231 employees and common people completed the questionnaires, and structural equation model of AMOS 18.0 was used. Results - From the empirical analysis, the outcomes are as followings. First, corporate ability association makes consumers feel proud. Second, corporate social responsible association makes consumers feel grateful. Third, both corporate ability association and social responsibility association let consumers be aware of global self-corporate brand congruity. Fourth, being conscious of each of pride, gratitude and global self-corporate brand congruity prompts consumers to behave positively toward corporate products. Fifth, mediation effects of pride and the congruity in the roles of corporate ability association on the positive behavior, and those of gratitude and the congruity in the roles of corporate social responsible association on the positive behavior are identified. Conclusions - Based on the results, it can be said that a marketing manager should endeavor to make consumers associate the corporate ability and social responsibility. However, the degree of consumers' feelings such as pride and gratitude can differ according to their cultural backgrounds. It is, therefore, needed to be explored by the types of feelings that can be caused more from the difference in cultural backgrounds by corporate association, and to be investigated differently and positively with behavioral effects on the corporate's products between the types.
