The purpose of this paper is to show that Williamson's counterexamples and Fara's paradox do not conclusively refute supervaluationism. I will achieve this purpose on the basis of local validity. In general, people regard supervaluational validity as global validity. And D-introduction, which is premise of Williamson's counterexamples and Fara's paradox, is justified only if we assume global validity. But it cannot correctly grasp supervaluational semantics, especially semantic character of D-operator. So I will show that validity of supervaluationism is local and define global validity by local validity. Strategy of this paper is to protect supervaluationism against Williamson's counterexamples and Fara's paradox by minimal modification of supervaluationism and to prove that supervaluational logic is not revisionary and weak for solving the sorites paradox.

Recently, as personal information utilization devices such as IoT, artificial intelligence, and wearable devices that focus on the individual have spread, privacy violations are also increasing. However, the privacy paradox of providing personal information to enjoy services while worrying is getting stronger. However, there are still preliminary studies on this. In this study, an intelligent home camera based on IoT technology was selected as a research object, and whether privacy paradox exists in the IoT environment, including smart home camera, was studied. To this end, the effect of perceived usefulness, a benefit factor of smart home camera use, and privacy concern, a risk factor, on intention to use was verified. In addition, it was investigated whether the relationship between privacy concerns and intention to use differs according to the presence or absence of use experience. In order to verify the research model, a survey was conducted with people with and without experience in using smart home cameras, and a total of 298 data samples were used for statistical analysis. As a result of the analysis, it was found that both perceived usefulness and privacy concerns had a positive effect on the intention to use, proving that privacy paradox exists in the IoT-based smart home camera environment. In addition, by analyzing the fact that privacy concerns have different effects on usage intentions depending on the user experience, it was verified that those with experience have a strong privacy paradox and those without experience have a weak privacy paradox. This study is meaningful because it seeks strategic implications to improve service and business performance by understanding the relationship between privacy attitudes and behaviors of IoT service providers, including smart home cameras.

The significance of Han medicine (韓醫學), the Korean traditional medicine, that has lasted throughout the past couple millenniums relies upon Han Philosophy distinguished by its uniqueness. In brief, the specificity of Han medicine is characterized by unity of spirit and body, part and whole. According to this theory, when curing a frozen shoulder, it is usually cured by acupuncturing the area around the part that aches, but also doing so on the area that is totally different from the aching part such as the opposite part of the body. In fact, this can be pursued only through aspects that enable one to realize the unity of part and whole, and a ground for this possibility bases upon the crux of Eastern Philosophy, I-ching(역), such as theory of Five Elements (음양오행) and Three Pillars(삼재). In Western set theory, the issues of Class(부류) and elements(요원), whole and part were independently discussed in the area of mereology, and the question of part and whole was encountered with aporia and paradox since Greek ancient philosophy. At the turn of this century, many philosophers endeavored to pursue academic inquiry to resolve this paradox, especially by Russell and Whitehead through ${\ll}$Principia Mathematica${\gg}$ at the beginning of this century. in the process, there came out a phrase 'Russell's Paradox'. Russell himself proposed a typological resolution as an answer to the inquiry. However, 'Russell's Paradox' still remains as an aporia even till present days. During medieval period, this inquiry was even considered as 'insolubia'. Throughout this paper, 1 attempt to provide an analytic aspect on 'Russell's Paradox' from an unique thinking method and perspective of Han medicine that embodies the concept of 'unity of part and whole'. To do so, 1 suggest a physiological model in the first place depicted by diagrams of Circle 원, Quadrangle 방, Triangle 각(CQT) that portray the logic of Hado or Hotu 하도 which is 'the pattern from the river Ho'. That is to suggest that CQT원방각 of Hado can De a logical foundation that explains the notions of spirit (정신,뇌), internal organs(장부), and meridian system which functions as a solution to the question of 'Russell's Paradox'. There are precedent academic works examining the issue from philosophical aspect such as Sangil Kim's ${\ulcorner}$Han medicine과 러셀역설 해의${\lrcorner}$ Han Medicine and Resolution of Russell's Paradox(2005), and this analysis will further attempt to critically examine such works from a perspective of Han medicine.

This paper revisits some old issues of irony, i.e., situational vs. verbal irony, and irony vs. paradox, in order to further clarify the issues. Although these issues seem to have been fully discussed, there are still unresolved and/or vague aspects that need to be accounted for. This paper also revisits the issue of theorizing the phenomenon of verbal irony, which has long been scrutinized by many philosophers and linguists including Aristotle, Grice, Sperber and Wilson, and recently, Utsumi and Attardo.

Recently, paradox management is a new paradigm to solve the management dilemmas. This is a new perspective and a creative way of thinking to draw the synergic effect by pursuing simultaneously the conflicting elements. As one method for the paradox management, this paper proposes a process of combining the TOC (Theory Of Constraints) and TRIZ (Russian Theory of Inventive Problem Solving) and applies to a dilemma case in business environments.

Recently, several studies in the field of privacy research suggested counterintuitive phenomenon about previous studies on existing perspectives. They claim that consistency of attitude and behavior does not exist, which is called privacy paradox. This study aims to clarify the relationship between intention to information disclosure and actual behavior based on the privacy paradox perspective. It attempts to explain the causes of privacy paradox phenomenon through the dual process theory being discussed in the field of behavioral economics. The results of empirical analysis are as follows. First, paired t-test analysis between intention to information disclosure and actual behavior was statistically significant. This means the existence of privacy paradox. Second, privacy risk had significant explanatory power to behavioral intention, and privacy trust had significant explanatory power to actual behavior. In conclusion, this study shows that negative belief influences decision making situation controlled by rational thinking whereas positive belief influences actual situations controlled by intuitive thinking.

The purpose of the paper is to analyze an effectiveness before and after implementation of the median arterial bus lanes operation. The paper includes a speed analysis based on the Downs-Thomson Paradox theory, and a reliability analysis based on variance analysis of arrival time. According to the speed analysis, some road sections are now under phase 2 according to the Downs-Thomson Paradox, which is a state in which the bus speeds are greater than the car speeds. In the future it is predicted that cars and buses will reach an equilibrium speed which is in phase 3 of the multi-modal equilibrium theory. According to the reliability analysis of arrival time at each bus stop, in roads of median arterial bus lanes. the variance of arrival time is generally smaller than after the scheme implemented in eight months later.

People are exposed to various media. After the Digital Revolution, quantitative expansion of the media is at a rapid pace. Because of the expansion of the media, advertising needs efforts that induce the audiences' reaction. Rhetorical devices are used as the efforts. This study noted the visual paradox of rhetorical devices because it is an effective representation device that induced audiences' reaction by deliberate contradiction and ambiguity. This study has defined the visual paradox based on define and classification of paradox in logic. This study also tried to reveal the relationship between images and text for signification by metalanguage because it is important to the visual paradox in advertising. And analyzed cases of Volkswagen ads to prove the research process. Finally identified that images and text interact to create a new meaning.

During the northern burning season, biomass burning is found north of the equator, while satellite estimates from the residual-type method such as the CCD method show higher ozone south of the equator. This discrepancy is called the tropical Atlantic paradox (Thompson et ai., 2000). We use satellite and ground-based measurements to investigate the paradox. When the background tropospheric ozone over the Pacific Ocean from TOMS measurements is subtracted from the latitudinal total ozone distribution (e.g. TOMS-Pacific method), the results show remarkable agreement with the latitudinal stratospheric ozone distribution using the CCD method. The latitudinal tropospheric ozone distribution using the CCD method, with a persistent maximum over the southern tropical Atlantic, is also seen in the latitudinal tropospheric ozone distribution using the TOMS-Pacific method. It suggests that the complicated CCD method can be replaced by the simple TOMS-Pacific method. However, the tropical Atlantic paradox exists in the results of both the CCD and TOMS-Pacific methods during the northern buming season. In order to investigate this paradox, we compare the latitudinal ozone distributions using the CCD and TOMS-Pacific methods by using the SAGE measurements (e.g. TOMS-SAGE method) and the SHADOZ ozonesoundings (e.g. TOMS-Sonde method) assuming zonally invariant stratospheric ozone, which is the same assumption as of the CCD method. During the northern burning season, the latitudinal distributions in the tropospheric ozone derived from the TOMS-SAGE and TOMS-Sonde methods show higher tropospheric ozone over the northern tropical Atlantic than the southern Atlantic due to a stronger gradient in stratospheric ozone relative to that from the CCD and TOMS-Pacific methods. This indicates that the latitudinal tropospheric ozone distribution can be changed depending on the data that is used to determine the latitudinal stratospheric ozone distribution. Therefore, there is a possibility that the north-south gradient in stratospheric ozone over the Atlantic can be a solution of the paradox.
