  • In accordance with the establishment of 200 nautical miles EEZ regime as a customary international law since the mid - 1980s, the area of global high seas became reduced relatively. On the other hand, the importance of high seas fishing ground became serious for the distant-water fishing states like Korea. But it can be expected that international dispute on the jurisdictional problem of the fishing vessels engaging high sea fishery will occur frequently owing to institutional inertia of the UNLOS Convention on this matter. "The Draft Agreement to Promote Compliance with International Conservation and Management Measures by Fishing Vessels on the High Seas" as an international code of conduct for responsible fishing which was adopted by FAO in 1993 is providing the more consolidating and definiting rules for jurisdictional responsibility of flag states to make completion the loophole of the UNLOS Convention. As a precondition for the effective control and enforcement of activities of the fishing vessels engaging high sea fishery, the Draft Agreement is providing some articles allowing the flag states to hold the rights of granting nationality, fishery permission, fishery supervision and control with punishment for the fishing vessels entitled to fly their own flag. Accordingly it can be evaluated that this Draft Agreement does not deviate on the whole from the traditional practice and the basic legal principle of the UNLOS Convention.

  • From 2018 to 2020, the United States has repeatedly imposed sanctions on the Chinese company Huawei, which has triggered strong nationalist sentiments on the Chinese Internet. This paper is a qualitative content analysis of Zhihu netizens' views on US sanctions against Huawei to explore how anti-Western centrism influences young people's narratives. The results showed that they believe the Huawei matter is a deliberate hegemonic act by the United States because it fears the decline of its own technological status. Moreover, it is direct evidence that the United States is deliberately destroying China's economic development environment to slow down China's rise, as well as a typical manifestation of the injustice of the liberal international order. A further analysis revealed that their narrative logic is obviously influenced by the following aspects: 1) The mentality of national glory derived from comprehensive national strength leads them to believe that U.S. sanctions against Huawei are an obstacle to China's rise. 2) National humiliation leads them to view U.S. sanctions as a constant insult to China. 3) China's superiority created by China's comprehensive national strength and its scientific and technological achievements in recent years has boosted its confidence to challenge the West's absolute progress. This study examines the impact of anti-Western centrism on Chinese nationalist sentiment and offers a bottom-level perspective on the debate over the crisis of the liberal order.

  • This study aims to analyze science-gifted elementary students' understanding of 'Living Things' with ontological domains. As research subjects, this study selected 80 science-gifted students who belonged to Education Institute for Science-gifted Elementary Students at University of Education, and this study came to the following conclusions. Firstly, the gifted students thought of animals as living things most, out of which humans accounted for the highest rate. They were also found to evaluate the importance of living things depending on benefits and harms to humans. Secondly, when judging 4 domains of living things, animals, plants, static inanimate objects and dynamic inanimate objects, the gifted students did not have difficulty judging animals, plants and static inanimate objects, but 4 of them judged the moon, a dynamic inanimate object, as a living thing. In the aspect of reaction time, they spent more time judging plants than animals. This study classified their standards of judgement on living things into ontological categories. As a result, it was found that 31 and 33 out of them had standards of judgement corresponding to the category of matter and the category of process respectively, and only 16 of them had standards of judgement corresponding to the category of mental states. Thirdly, how to make a waterwheel and images of euglena and paramecium were shown to 10 of the gifted students who suggested simple movements as characteristics of living things. As a result, 7 of them changed their standards of judgement from the category of matter to the category of process, while 3 of them changed from the category of matter to the category of mental states.

  • There has been no nuanimous analysis of specific indefinites. It is still disputed even whether specificity is a matter of semantics of pragmatics. In this paper, I introduce some properties of specific indefinites, and explain them based on the meaning of specificity. Specificity intuitively means that the speaker or someone else in the context has some individual in mind, which is generally accepted among liguistics. The main issue is how to represent the meaning of 'have-in-mind'. I review some philosophical discusstions of cognitive contact and show that when the use of an expression involves 'have-in-mind', the expression is rigid designator in the belief of the agent who has an individual in mind. in the use of a specific indefinite, this applies only to the information state of the agent of 'have-in-mind'. To represent this asymmetry, I propose a new theory of dynamic semantics, in which a common ground consists of multiple information states, as many as the number of the participants in a conversation. Moreover, each information state is structured as a set of epistemic alternatives, which is a set of possible information states of a participant in the context. Based on this semantics, the properties of specific indefinites are explained.

  • Concentrations of suspended particulate matters (SPM) and their distribution patterns were monitored three times in the East China Sea during the winter season in 1998 and 1999. SPM concentrations showed significant temporal variations controlled by the atmospheric conditions and sea states. In coastal area, SPM values were about 10-20 mg/l in fair weather conditions, but exceeded 100mg/l during the storm periods. Turbid waters were distributed widespread in the continental shelf of the East China Sea and the coastal area of the Korean Peninsula, and these two areas were connected along a NE-SW direction. The distribution patterns of turbid waters were interpreted as representing the transport behavior of suspended matter. Although the primary source of inner shelf mud deposits of Korea seems to be the Korean Peninsula, contribution from the East China Sea to the coastal area of Korea increases especially during the winter season.

  • Excitatory amino acids (EAA) are thought to play an important role in producing cell death associated with ischemic and traumatic spinal cord injury. The present study was carried out to determine if the response characteristics of spinal sensory neurons in segments adjacent to degeneration sites induced by EAA are altered following these morphological changes. Intraspinal injections of quisqualic acid (QA) produced neuronal degeneration and spinal cavitation of gray matter. The severity of lesions was significantly attenuated by pretreatment with a non-NMDA antagonist NBQX. In extracellular single unit recordings, dorsal horn neurons in QA injected animal showed the increased mechanosensitivity, which included a shift to the left in the stimulus-response relationship, an increased background activity and an increase in the duration of after-discharge responses. Neuronal responses, especially the C-fiber response, to suprathreshold electrical stimulation of sciatic nerve also increased in most cases. These results suggest that altered functional states of neurons may be responsible for sensory abnormalities, e.g. allodynia and hyperalgesia, associated with syringomyolia and spinal cord injury.

  • Drugs can have various adverse effects on the immune system including unintended immun-osuppression, induction of both drug-specific immune responses (including drug allergies) and non-specific immunostimulation (including autoimmune reactions), and direct activation of effector mechanisms (such as histamine release). As a practical matter, the Center for Drug Evaluation (CDER) relies on standard non-clinical toxicology studies to detect unintended immunosuppression. Specific assays using guinea pigs and mice are available to identify drugs that can induce immune-mediated dermal hypersensitivity reactions. Respiratory and systemic hypersensitivity and autoimmune reactions are more difficult to model in non-clinical studies. Unintended nonspecific immunstimulation can be detected in animal studies. CDER is currently developing specific guidance for evaluating potential drug immunotoxicity.

  • On this earth, we usually encounter three states of matter: solid, liquid, and gas. Those are the states we experience directly and most often in everyday life. However, if we consider the whole universe, more than 99.99 percent of our visible universe is in plasma state. The earth is in very unusual situation in the universe, and it is great virtue to whole creatures on this planet. In the beginning of the universe, however, there was only plasma. The other stuff came later after then. The Big Bang, beginning of our universe, was dominated by high-temperature plasma. It is where we all came from, and it continues to play a major role not only in our universe but also in various industrial applications of human being.

  • Accretion flows around black holes and neutron stars emit high energy radiation with varying spectral and timing properties. Observed timing variations, both short and long-term, point to the existence of a mechanism, dictated by the flow dynamics, and not by the stellar surface or magnetic fields, that is common in both. Spectral energy distributions of multiple sources indicate that the Comptonization process, the dominant mechanism for changing states in X-ray, takes place inside the flow that has similar physical properties in both the objects. In a series of observational and numerical studies, we enquire about the following: 1. Is there a steady state configuration for accreting matter around black holes that can explain spectral and timing properties? 2. Could a similar formalism explain spectral and timing properties of accretion around neutron stars? 3. Could there be a generalized flow configuration for accreting matter around such compact objects? Furthermore, we show that a unified spectral model can be constructed based on the generalized flow configuration, common to black holes and neutron stars.

  • The complete active space self-consist field method followed by the internally contracted multireference configuration interaction method has been used to compute the potential energy curves of $X^2\prod_g$, $a^4\prod_u$, $A^2\prod_u$, $b^4\sum_{g}^{-}$, and $B^2\sum_{g}^{-}$ states of $S{_2}^+$ cation with large correlation-consistent basis sets. Utilizing the potential energy curves computed with different basis sets, the spectroscopic parameters of these states were evaluated. Finally, the transition dipole moment and the Franck-Condon factors of the transition from $A^2\prod_u$ to $X^2\prod_g$ were evaluated. The radiative lifetime of $A^2\prod_u$ is calculated to be 887 ns, which is in good agreement with experimental value of $805{\pm}10$ ns.
