The purpose of the study is to investigate the relation between marital communication types and self-esteem demographic-socioligical variables to eliminate the methodlogical contradiction of previous studies, this study aimed as follows: (1) correlation between marital communication types and all the independent variables, such as self-esteem, sex, age, academic history, mate selection type, family type, duration of marriage, religion, etc. and marital communication types. (2) discriminating powers of marital communication types by way of the variables mentioned above. In this study questionaire was used on 392 married Seoulites, which consists of two scales and 9 items. In order to verify the hypotheses, the following two methods were used: (1) LOGIT program to the correlation between norminal scale and /or interval scale. (2) discriminating analysis of marital communication types by way of the variables. The results of the study are as follows: (1) Only 4 variables, such as self-esteem, sex, duration of marriage and academic history, correlate with marital communication types in level P<0.05 (2) According to the discriminating analysis of the variables mentioned above, marital communication types cannot be predicted as the predictive power is only 32.2%. (3) Correlation coefficent of authoritic communication type is higher males than females and higher low degree group of self-esteem than high degree group. (4) In the some communication types, direction of correlation coefficent is different in the some variables.

Recently, DC distribution systems have become a hot issue because of the increase in digital loads and DC generation systems according to the expansion of renewable energy technologies. To obtain the practical usage of DC electricity, safety should be guaranteed. The main concerns for safety are twofold: one side is human protection against electric shocks, and the other is facility protection from short faults. "Effects of current on human beings and livestock" (IEC 60479) defines a human body impedance model in electric shock conditions that consists of resistive components and capacitive components. Although the human body impedance model properly works in AC electricity, it does not well match with the electric shock behavior in DC electricity. In this study, the contradiction of the human body impedance model defined by IEC 60479 in case of DC electricity is shown through experiments for the human body. From the analysis of experimental results, a novel unified human body impedance model in electric shock conditions is proposed. This model consists of resistive components, capacitive components, and an inductance component. The proposed human impedance model matches well for AC and DC electricity environments in simulation and experiment.

To address the contradiction between data aggregation and data security in wireless sensor networks, a Recoverable Privacy-preserving Integrity-assured Data Aggregation (RPIDA) scheme is proposed based on privacy homomorphism and aggregate message authentication code. The proposed scheme provides both end-to-end privacy and data integrity for data aggregation in WSNs. In our scheme, the base station can recover each sensing data collected by all sensors even if these data have been aggregated by aggregators, thus can verify the integrity of all sensing data. Besides, with these individual sensing data, base station is able to perform any further operations on them, which means RPIDA is not limited in types of aggregation functions. The security analysis indicates that our proposal is resilient against typical security attacks; besides, it can detect and locate the malicious nodes in a certain range. The performance analysis shows that the proposed scheme has remarkable advantage over other asymmetric schemes in terms of computation and communication overhead. In order to evaluate the performance and the feasibility of our proposal, the prototype implementation is presented based on the TinyOS platform. The experiment results demonstrate that RPIDA is feasible and efficient for resource-constrained sensor nodes.

Numerical analysis was conducted to characterize the gas flow field and particle deposition on a horizontal freestanding semiconductor wafer under the laminar flow field at vacuum environment. In order to calculate the properties of gas, the gas was assumed to obey the ideal gas law. The particle transport mechanisms considered were convection, Brownian diffusion and gravitational settling. The averaged particle deposition velocities and their radial distributions fnr the upper surface of the wafer were calculated from the particle concentration equation in an Eulerian frame of reference for system pressures of 1 mbar~1 atm and particle sizes of 2nm~10$^4$ nm(10 ${\mu}{\textrm}{m}$). It was observed that as the system pressure decreases, the boundary layer of gas flow becomes thicker and the deposition velocities are increased over the whole range of particle size. One thing to be noted here is that the deposition velocities are increased in the diffusion dominant particle size range with decreasing system pressure, whereas the thickness of the boundary layer is larger. This contradiction is attributed to the increase of particle mechanical mobility and the consequent increase of Brownian diffusion with decreasing the system pressure. The present numerical results showed good agreement with the results of the approximate model and the available experimental data.

A scenario known as conflict in face recognition may arise as a result of some disparity-related issues (such as expression, distortion, occlusion and others) leading to a compromise of someone's identity or contradiction of the intended message. However, addressing this requires the determination and application of appropriate procedures among the various conflict theories both in terms of concepts as well as resolution strategies. Theories such as Marxist, Game theory (Prisoner's dilemma, Penny matching, Chicken problem), Lanchester theory and Information theory were analyzed in relation to facial images conflict and these were made possible by trying to provide answers to selected questions as far as resolving facial conflict is concerned. It has been observed that the scenarios presented in the Marxist theory agree with the form of resolution expected in the analysis of conflict and its related issues as they relate to face recognition. The study observed that the issue of conflict in facial images can better be analyzed using the concept introduced by the Marxist theory in relation to the Information theory. This is as a result of its resolution strategy which tends to seek a form of balance as result as opposed to the win or lose case scenarios applied in other concepts. This was also consolidated by making reference to the main mechanisms and result scenario applicable in Information theory.

The aim of this study is to determine the property of Daesoon thought in theory of God. The difference with precedent research is that this study catch the point in which theism as theology conflicts ontology as philosophy. It is elusive without philosophical analysis to detect this point for reasons of religious expression on scriptures. To find this point is beginning of academic communication at religious position. So I tried to draw boundary between theology and philosophy in Daesoon thought so as to apprehend Daesoon thought treats the contradiction of that. The contradiction is found that hierarchy between Sangje and taegeuk reverses on Daesoon thought. Fundamentally two substance can't be arranged to ontology but only one can be. It seems that Daesoon thought has got antinomy. However superiority of Daesoon thought is appeared at this point. The antinomy is just the process to absolute truth of Tao. That is a progressive system of thought in both religious and philosophical aspect. Finally, the result of this study can be organized with five items. First is to get new direction to study of Daesoon thought to catch the clash between theology and ontology. Second is that Daesoon thought can communicate the mainstream philosophy like Hegel's while the argumentation makes progress with Hegel's thought. Third is that Daesoon thought has originality in ontology of tao, mugeuk, tageuk as compared with neo-Confucianism. Forth is that theology of Daesoon thought has the possibility to peace among religions. Fifth is that Daesoon thought transcends religion and philosophy to absolute truth. Particularly, the noteworthy item is about peace among religions as theme of religious practice as the needs of times. The conflict of religion is very serious impact to historic future. So Daesoon thought suggests that all the religions harmonize with each other in universality and respect each other in distinctiveness. It makes it possible to aims for world peace beyond theory to practical orientation on religious creed. In history of philosophy the dialetic of Hegel is the very adequate to explain that principle. Hegel argued that human mind can reach to the absolute knowledge at 『Phänomenologie des Geistes』. He elucidates the process that mind attain the absolute knowledge through movement of negation at 『Phänomenologie des Geistes』. The dialetics leads all the process of mind to finality of the absolute spirit.

This study investigates the negative perceptions (veganphobia) held by consumers toward vegan diets and fashion and aims to foster a genuine acceptance of ethical veganism in consumption. The textual data web-crawled Korean online posts, including news articles, blogs, forums, and tweets, containing keywords such as "contradiction," "dilemma," "conflict," "issues," "vegan food" and "vegan fashion" from 2013 to 2021. Data analysis was conducted through text mining, network analysis, and clustering analysis using Python and NodeXL programs. The analysis revealed distinct negative perceptions regarding vegan food. Key issues included the perception of hypocrisy among vegetarians, associations with specific political leanings, conflicts between environmental and animal rights, and contradictions between views on companion animals and livestock. Regarding the vegan fashion industry, the eco-friendliness of material selection and design processes were seen as the pivotal factors shaping negative attitudes. Furthermore, the study identified a shared negative perception regarding vegan food and vegan fashion. This negativity was characterized by confusion and conflicts between animal and environmental rights, biased perceptions linked to specific political affiliations, perceived self-righteousness among vegetarians, and general discomfort toward them. These factors collectively contributed to a broader negative perception of vegan consumption. In conclusion, this study is significant in understanding the complex perceptions and attitudes that con- sumers hold toward vegan food and fashion. The insights gained from this research can aid in the design of more effective campaign strategies aimed at promoting vegan consumerism, ultimately contributing to a more widespread acceptance of ethical veganism in society.

China, the nation which reigns the society consisted of several ethnic groups, has been interested in universal virtues since its early eras, due to the social demand for their integration. Confucianism, therefore, traditionally has been executing this function as a transcendant world, and at present the Marxism takes its role instead. After its reformation and opening, the market economy was allowed to set in China, which means that the traditional ideology of integration comes to face the crisis occurred by new trend of the individualism which is gradually spreading. The people who make the policies and the intellectual people in China who noticed these phenomena, are trying to make measures to cope with this contradiction. Despite of their trials, they are destined to find nothing but powerlessness in front of the powerful marketing strategy of the commercialism which adroitly adapted to their measures. In this situation, the transcendant world to reach, which these people are appealing again is the totalitarian ideology that persistently has been maintained through history of China. The movie, Hero, is the one of these attempts. This paper offers you the analysis of this cultural agony of contemporary China.

This paper takes Zhaoxing Dong village in Guizhou Province as the research object. The purpose is to study the continuity of landscape context in Dong Village. The research process includes specification on the evaluation system of Dong village landscape context by AHP method, and use of the questionnaire survey method in sequence, according to the specific situation of Zhaoxing Dong village, and this study develops a specific questionnaire that modifies the evaluation system suited to reflect specific problems. Through the analysis of the specific questionnaire and recycling in Zhaoxing Dong village, this study found that Zhaoxing Dong village as a whole is over commercialized due to the vigorous development of tourism service industry. As a result, whether it is experts, foreign tourists or local villagers, the rating of the village landscape is low. There are three problems in the village landscape context: historical continuity, invisible cultural heritage and contradiction in protection and development. The results of this paper provides a future direction for the protection and inheritance of Zhaoxing Dong village.

Waste sector has been a target of abatement policies by the most governments, even though its greenhouse gas (GHG) emission is not so high, since it is related to almost of other sectors. This study propose new GHG calculation equations which resolves logical contradiction of IPCC GL (Intergovernmental Panel on Climate Change Guideline) equations by including waste-to-energy effects. According to two GHG calculation equations, GHG emission inventory and BAU by the year 2050 have been computed. And GHG abatement potential and marginal cost for the five abatement policies carefully selected from the previous researches have been calculated for the year 2020. The policy that makes solid fuel like RDF from flammable wastes and uses them as combustion fuel of electricity generations has been found to be the most efficient and effective one among five policies. The cumulative abatement amount when five policies not mutually exclusive are applied sequentially has been reckoned.
