Design to Improve Educational Competency Using ChatGPT

이충형 한국인터넷방송통신학회 2024 International Journal of Internet, Broadcasting an Vol.16 No.1

Various artificial intelligence neural network models that have emerged since 2014 enable the creation of new content beyond the existing level of information discrimination and withdrawal, and the recent generative artificial intelligences such as ChatGPT and Gall-E2 create and present new information similar to actual data, enabling natural interaction because they create and provide verbal expressions similar to humans, unlike existing chatbots that simply present input content or search results. This study aims to present a model that can improve the ChatGPT communication skills of university students through curriculum research on ChatGPT, which can be participated by students from all departments, including engineering, humanities, society, health, welfare, art, tourism, management, and liberal arts. It is intended to design a way to strengthen competitiveness to embody the practical ability to solve problems through ethical attitudes, AI-related technologies, data management, and composition processes as knowledge necessary to perform tasks in the artificial intelligence era, away from simple use capabilities. It is believed that through creative education methods, it is possible to improve university awareness in companies and to seek industry-academia self-reliant courses.

A Tale of Team Infinity

이충형 한국분석철학회 2017 철학적 분석 Vol.0 No.38

I construct a decision-theoretic puzzle based on the assumption that it is possible for there to be a team of infinitely many people whose utility scales are unbounded. I argue that the puzzle can be resolved, without requiring that no rational agent should have unbounded utility scales, by employing a more general definition of utility, on which utility is measured not by amounts of returns but by changes in total wealth.

What If Instantaneous Relative Velocity Is Real In Special Relativity: Relative Simultaneity As Indexed Relation

이충형 한국분석철학회 2022 철학적 분석 Vol.- No.47

It is a standard view in Special Relativity that simultaneity relations are ternary relations that hold for three items: x is simultaneous with y relative to z. Noting the connection between clock synchrony and the one-way speed of light, I argue that if it is indeed a physical fact that the one-way speed of light has a certain value, then simultaneity relations in Special Relativity are about local facts that obtain in finite spatiotemporal regions, and so it is natural and plausible to take simultaneity relations to be quaternary relations among four items, i.e., x is simultaneous with y relative to z at p, where p is a spatiotemporal point in Minkowski spacetime. This has the added benefit of defusing Hanoch Ben-Yami (2006)’s argument that Standard Synchrony yields inconsistent results when applied to non-inertial observers.

Simultaneity Relations Relative to Multiple Observers in Special Relativity

이충형 한국과학철학회 2022 과학철학 Vol.25 No.2

It is a standard practice in special relativity to define a simultaneity relation relative to an inertial observer or frame of reference. This practice is based on two assumptions: (1) A simultaneity relation relative to an inertial observer should be defined from the worldline of the observer (and the structural features of Minkowski spacetime); and (2) a simultaneity relation of special relativity should be defined relative to a single inertial observer, not relative to multiple observers as such. I challenge these two assumptions by presenting simultaneity relations defined relative to multiple inertial observers. I show that they are operationally definable and that they are also explicitly definable from the causal connectibility relation and the worldlines of the observers. They are thus legitimate simultaneity relations, and so the relative simultaneity relation of special relativity is not uniquely definable from the causal connectibility relation.

Instantaneous velocity and the causal explanation problem

이충형 한국과학철학회 2013 과학철학 Vol.16 No.1

Velocity reductionism is the view that the instantaneous velocity of a body at an instant t is reducible to a relation among the body’s positions at the various moments in a neighborhood of t. On the other hand, velocity primitivism takes a body’s instantaneous velocity at t as an intrinsic property belonging at that instant to the body, which is as primitive as the body’s position at t. Regarding the debate between these two views, this paper aims to do three things: First, I present several examples illustrating the philosophical and physical significance of this debate. Second, I argue that, contrary to common beliefs of many physicists and philosophers, the limit of average velocities is not truly instantaneous. And third, Marc Lange (2005, 2009) recently claimed that instantaneous velocity, if velocity reductionism is correct, cannot play the causal and explanatory roles that classical physics is often interpreted as demanding of them. I argue that Lange’s criticisms on velocity reductionism are unfounded, i.e., that the causal and explanatory roles can be ascribed to instantaneous velocity in accordance with velocity reductionism.

A Puzzle of Infinitely Many Mutually Independent Bets

이충형 한국분석철학회 2018 철학적 분석 Vol.0 No.40

I present a new puzzle where a player is offered infinitely many mutually independent bets each of which has a positive expected return but which collectively lead to a net loss almost surely with probability 1. This puzzle is similar to the one presented by Vann McGee (1999) where there are infinitely many mutually dependent bets each of which has a positive expected return but whose cumulative outcome is a sure loss. Both puzzles pose a serious threat (while my new puzzle, because of the mutual independence of the bets, poses a more serious threat) to the principle of expected utility maximization because the principle seems to recommend us to take each and every one of the bets whereas it does not seem rational to take all of them. I then argue that the two puzzles can be solved in a uniform way: It is impossible to take all of the bets if you have only a finite amount of money and it is not irrational to take them all if you have an infinite amount of money.

Infinitely Iterated Possibility: Worlds Reachable Only With Infinitely Many Transfers

이충형 한국논리학회 2022 論理硏究 Vol.25 No.3

Nathan Salmon (1989) famously argues that there are impossible worlds that are nevertheless possibly ... possibly possible. Modifying his argument and utilizing a fractal structure called the Koch snowflake, I argue that there are impossible worlds that are possibly ... possibly possible not for any finite degree of nesting but only for an infinite degree of nesting. To accommodate this result, I suggest that the syntax and semantics of modal logic be augmented so that it allows infinite iterations of modal operators.

The Prevalence of Chronic Diseases among Migrants in Korea According to Their Length of Stay and Residential Status

이충형,윤재문,한종수,박상민,박영수,홍승권 대한가정의학회 2012 Korean Journal of Family Medicine Vol.33 No.1

Background: Migrant health is becoming public health issues, as the migrant populations are increasing and their length of stay is prolonged. This study aims to analyze the differences in prevalence of chronic diseases among migrants according to length of stay and residential status. Methods: An initial population pool were 3,024 who were assessed with health screening programs by Migrant Health Association. 2,459 migrants were selected for final analysis. Via Stata 10 we conducted univariate logistic regression analysis to examine the effects of their length of stay and residential status on the prevalence of hypertension, diabetes, dyslipidemia, and obesity. In the final analysis, the result of each sex was adjusted for age, nationality, length of stay, and residential status via multiple logistic regression analysis. Results: Longer length of stay tends to increase the prevalence of hypertension in male; 4-6 year stay-duration group demonstrated statistically significant excess compared to 1 year or less stay-duration group (adjusted odds ratio [OR], 1.39;confidence interval [CI], 1.01 to 1.92). After adjustment, male migrants stayed more than 7 year showed considerably higher dyslipidemia than male migrants stayed less than 1 year (adjusted OR, 1.95; CI, 1.05 to 3.64). Compared to the group with 1 year or less stay-duration, the prevalence of obesity in male was significantly higher among 4-6 year (adjusted OR, 1.65; CI, 1.17 to 2.32)and 7 year or more stay-duration group (adjusted OR, 1.65; CI, 1.11 to 2.45). Conclusion: Longer length of stay correlated to higher prevalence of hypertension, dyslipidemia, and obesity among some population of migrants. So more researches and new developing policies are needed for this problem.
