The purpose of this study was to analysis the causal model between self-directedness, learning flow, career decision and self-efficacy, and career exploration behavior of undergraduate students. A survey was conducted on 604 undergraduate students, and Structural Equation Modeling was used to analyze. The major findings were as follows: First, learning flow and career decision self-efficacy were found to have positive impacts on career exploration behavior. However, self-directedness was found to have no significant direct impacts on career exploration behavior. Second, self-directedness was found to have positive impacts on learning flow and career decision self-efficacy. Finally, learning flow and career decision self-efficacy were found to have perfect mediating effects on the relationships between self-directedness and career exploration behavior. Considering the size of the specific indirect effect, the mediating effects of learning flow was relatively larger than those of career decision self-efficacy. Based on the results, discussions to increase career exploration behavior were made as well as suggestions for future research.

With the dramatic development of science and technology since the twentieth century, attempts to overcome human's natural and physical limitations through technology have actually reached a peak. Transhumanism is a movement that strongly affirms these human technological attempts. However, this optimistic belief of transhumanism in technology meets the strong resistance of opponents contending that transhumanism might destroy human nature and severely undermine human values and rights. The focus of the transhumanism debate lies in what technology means to humans. However, in order to exactly grasp the essence of transhumanism, we should first consider our 'life-world', where technology and humans are closely intertwined. The word 'life-world(Lebenswelt)' which originally comes from Husserl, is an open and universal world as a horizon that is the basis of all human practical activities and at the same time encompasses its products in itself. According to Husserl, the process of incorporating human products into the life-world is a kind of 'familiarization' process through which specific theories and techniques are harmonized with our lives in the life-world. Such harmonization and familiarization of technology could be also considered a humanization of technology. It is a process in which technology is assimilated and corresponds to the finiteness of human and the life-world. In this sense, we could say that the transhumanistic attempts are just a natural expression of human desire to be perfect in the life-world and that they should not be overly concerned or overestimated.

The end of the 20th century, along with the popularity of new media technology and the rise of new media art, dance as a visual art, and body language art, has the features of more and more rich and changeful. In today's Internet booming new media environment, many different fields, such as film and theater, computer technology, digital art, etc.) with its commonness and characteristics of all kinds of interaction between the creation, produced a new interdisciplinary research with theoretical model. When cross-border interactions between various areas become a hot topic at the same time, the traditional form of dance performances are also seeking new breakthrough. Canada's famous social psychologist McLuhan believes that modern is retrieving lost over a long period of time "overall" feel, return to a feeling of equilibrium. The audience how to have the characteristics of focus on details of visual art back to the "overall" feel worthy of study. At the same time, the new media in today's digital dance teaching in colleges and universities dancing education remains to be perfect and popular, if continue to use the precept of the traditional teaching way blindly, so it is difficult to get from the development of the current domestic dance overall demand. In this paper, the main body is divided into two parts, the first chapter is the study of image device dance performance art, the second chapter is the research of digital dance teaching application system, thus further perspective of media technology to explore dance art crossover practice under the new media environment and mode of transmission.

The study was intended to explore the relevance of the variables below, assuming that the intolerance of uncertainty and dichotomous thinking would represent sequential serialized effects in the relationship between perfectionistic self-presentation and social anxiety. The data of this study were collected on questionnaire survey of 252 adult men and women in Seoul using perfectionistic self-presentation scale, social interaction anxiety scale, social phobia scale, intolerance of uncertainty scale and dichotomous thinkingI-30R as index, which results are as follow. First, intolerance of uncertainty and dichotomous thinking showed perfect mediation effects on the relationship between perfectionistic self-presentation and social anxiety. Intolerance of uncertainty and dichotomous thinking were identified as contributing factors to the development and preservation of social anxiety by perfectionistic self-presenters. Second, in the relationship between perfectionistic self-presentation and dichotomous thinking, intolerance of uncertainty showed mediation effect. And in the relationship between intolerance of uncertainty and social anxiety, dichotomous thinking showed mediation effect. This suggested that if tolerance of uncertainty was deficient, it was likely to lead to dichotomous thinking. And a dichotomous thinking has prompted or accelerated negative cognitive biases resulting from intolerance of uncertainty, triggering and deepening social anxiety. Lastly, the limitations of this study and future research direction were suggested.

The present study examined the possibility of cryopreservation of the D-shaped and umbo larvae of arkshell (Scapharca broughtonii), in terms of the survival rates after freezing and thawing. D-shaped and umbo larvae of arkshells were obtained from a shellfish farming on Yosu city. The average shell lengths were $93.3 \pm 10.1 \mu$m and $201.7 \pm 13.5 \mu$, respectively. Five cryoprotectants (CPAs), dimethyl sulfoxide (DMSO), glycerol, ethylene glycol (EG), propylene glycol (PG), and methanol, were tested at the concentrations of 1.5, 2.0 and 2.5 M. After larvae suspended in CPAs, cryoprotectants were loaded in 0.5 ml straws at a larval density of 50-100 larvae per straw, and epuilibrated for 10 and 20 minute at room temperature ($23^{\circ}C$), repectively. Straws were cooled at a rate of $1^{\circ}C$/min from $0^{\circ}C$ to $-12^{\circ}C$, held for 5 min at $-12^{\circ}C$, and then cooled at $2^{\circ}C$/min to $-35^{\circ}C$ and equilibrated for 5 min followed by plunging in liquid nitrogen. After storage in liquid nitrogen for 1 day, straws were thawed in a $30^{\circ}C$ water. As soon as straws were observed to melt, larvae were diluted with an equal volume of ASW and then washed twice with a large volume of ASW at an interval of 2 min to unload the CPAs. The results showed that after equilibration for 10 and 20 minute at room temperature, no larvae survived using methanol as CPAs, and it was observed that larval shells all open slightly, and larval flesh broke down and slopped over the shells. The highest survival rates (D-shaped larvae: 77.6%, umbo larvae: 59.3%) were obtained with 2M DMSO, and 1.5M glycerol yielded survival rates of 53.8% for D-shaped larvae and 37.5% for umbo larvae. The surviving D-shaped larvae showed active rotary motion and perfect membrane integrity and cytoplasmic normality, and the vigorous movement of veliger cilia was observed inside the closed shells. The breakdown of tissue occurred in the abnormal larvae, and the isolated cell often run out of shells.

Objective: This study aimed to develop loop-mediated isothermal amplification (LAMP) combined with lateral flow dipstick (LFD) and compare it with LAMP-AGE, polymerase chain reaction (PCR), and standard Salmonella culture as reference methods for detecting Salmonella contamination in animal products and animal production environmental samples. Methods: The SalInvA01 primer, derived from the InvA gene and designed as a new probe for LFD detection, was used in developing this study. Adjusting for optimal conditions by temperature, time, and reagent concentration includes evaluating the specificity and limit of detection. The sampling of 120 animal product samples and 350 animal production environmental samples was determined by LAMP-LFD, comparing LAMP-AGE, PCR, and the culture method. Results: Salmonella was amplified using optimal conditions for the LAMP reaction and a DNA probe for LFD at 63℃ for 60 minutes. The specificity test revealed no cross-reactivity with other microorganisms. The limit of detection of LAMP-LFD in pure culture was 3×10² CFU/mL (6 CFU/reaction) and 9.01 pg/μL in genomic DNA. The limit of detection of the LAMP-LFD using artificially inoculated in minced chicken samples with 5 hours of pre-enrichment was 3.4×10⁴ CFU/mL (680 CFU/reaction). For 120 animal product samples, Salmonella was detected by the culture method, LAMP-LFD, LAMP-AGE, and PCR in 10/120 (8.3%). In three hundred fifty animal production environmental samples, Salmonella was detected in 91/350 (26%) by the culture method, equivalent to the detection rates of LAMP-LFD and LAMP-AGE, while PCR achieved 86/350 (24.6%). When comparing sensitivity, specificity, positive predictive value, and accuracy, LAMP-LFD showed the best results at 100%, 95.7%, 86.3%, and 96.6%, respectively. For Kappa index of LAMP-LFD, indicated nearly perfect agreement with culture method. Conclusion: The LAMP-LFD Salmonella detection, which used InvA gene, was highly specific, sensitive, and convenient for identifying Salmonella. Furthermore, this method could be used for Salmonella monitoring and primary screening in animal products and animal production environmental samples.

The main purpose of this dissertation is a introductive proposal to reconstruct confucian moral principles. The most classical question in moral principles is : what is the good. In order to reconstruct confucian moral principles, this dissertation begin with question of what is the good in confucian moral principles. Confucianism believe in reality of the human good mind and good nature. Confucian the human good mind and good nature is comprised of benevolence, righteousness, propriety and wisdom. Benevolence, righteousness, propriety and wisdom(四德) is the origin of morality. Confucian's moral principles of human relationship is none other than conscientiousness and altruism. Conscientiousness is a principle of self-cultivation and self-revelation. As to altruism, confucious said, "the man of perfect virtue, wishing to be established himself", or "do not impose on others what you do not desire others to impose upon you." Altruism is rectified as a principle of reciprocity methodology of the making of whole kingdom peaceful in The Great Learning. Confucian golden rule(conscientiousness and altruism is equal to Kantian categorical imperative in The Fundamental principles of Metaphysics of Ethics. : Act only on that maxim through which you can at the same time will that it should become a universal law ... etc. Kant's three principles of moral philosophy(Categorical Imperatives) imply that the idea of universality, freedom, and the kingdom of ends. We contrast confucian moral principles with Kant's three principles of Categorical Imperatives. In conclusion, confucian moral principles implicate Kant's principle of universalizability and impartiality.

The purpose of this study is to verify the influence of volunteering on the sense of community and the community capacity, and the mediating effect of the sense of community on the relationship between volunteering variables(the period and satisfaction of volunteering) and the community capacity as well. Study population is 1,416 elderly volunteers who participated in the government-sponsored elderly volunteer program for prevention of depression and suicide in 2016. The results show that the experience of volunteering plays an important role in improving the sense of community and the community capacity among the older participants. As for the analysis of the mediating effect, the sense of community has a perfect mediating effect between the period of volunteering and the community capacity, and a partial mediating effect between volunteering satisfaction and the community capacity. Based on these findings, the theoretical and practical implications were discussed.

The purpose of this study is to closely examine causality on the married-working women's depression. For this, the analytical materials were used the primary Seoul Metropolis Welfare Panel survey data. 507 married-working women in their 20s~50s were selected among survey subjects of Seoul Metropolis Welfare Panel data. The analytical method was used the structural equation model. As a result of analysis, it could be known that the path of perfect mediating effect in depression was formed after passing through the benefits satisfaction and the marital happiness from gender role attitude in the married-working women and that the benefits satisfaction has the partial mediating effect between depression and marital happiness. Suggesting a plan for getting rid of depression in the married-working women based on the results of this study, first of all, the married-working women's depression is greatly accredited to what our society regards domestic work yet as woman's role. Thus, the policy-based measure is demanded that can support for working women to be possibly compatible in work and family life and that can induce men's participation in household affairs and child-rearing in such context. Second, it was indicated that the more the married-working women adhere strictly to the gender role attitude of traditionalism, the lower result the marital happiness and benefits satisfaction have. Considering this, a plan for activating welfare system and family-friendly system is demanded that can change gender role value in traditionalism, which is being left in our society. Third, to promote marital happiness that has great influence upon the married-working women's depression, there is a need of seeking a plan, which further intensifies the family services including the marital education and the parent education.
