STUDIUM PORÓWNAWCZE ANALIZY DYSKURSU KOREAŃSKIEGO FILMU „POKOJÓWKA” – NA PRZYKŁADZIE FILMÓW Z 1960 I 2010
Korean legendary film director Kim Ki-Young’s 1960 work The Housemaid was remade in 2010 by director Im Sang-Soo. The study of the two films can be found as a comparative study of cinematic studies on sound analysis and genre analysis, and a sociological study on social images. However, few studies have looked with a discourse oriented approach. Discourse in the movie is not only a window for communication between characters, but also an important device with non-verbal elements, so it can be said to be discourse has a high importance as an analysis target. This study analyzes the film discourse according to Erving Goffman’s dramaturgical analysis to find out the differences between the characters. This study can be said is meaningful in that it has the characteristics of interdisciplinary research in linguistics and film studies through discourse analysis of two films with different periods.Dzieło koreańskiego reżysera Kim Ki-Younga o tytule Pokojówka po swoim debiucie w 1960 roku, doczekało się w 2010 nowego obrazu w wizji reżysera Im Sang-soo. Oba te filmy mogą być traktowane jako materiał badawczy nauk filmowych w zakresie analizy fabuły i gatunku, jak i studium socjologiczne obrazu społeczeństwa. Jednocześnie niewiele badań dotyka dyskursu, który w tych filmach jest nie tylko obrazem komunikacji między postaciami, ale także ważnym narzędziem wyposażonym w elementy niewerbalne, uzupełniającym tło komunikacji. Artykuł niniejszy bada więc dyskurs filmowy w świetle analizy teorii dramaturgicznej Ervinga Goffmana, mając na celu ukazanie różnic między bohaterami obu tych dzieł. Wykazuje także cechy interdyscyplinarności badań na styku nauk o filmie i językoznawstwa w postaci analizy dyskursu filmów z różnego okresu
Selection of the Most Probable Best
We consider an expected-value ranking and selection problem where all k
solutions' simulation outputs depend on a common uncertain input model. Given
that the uncertainty of the input model is captured by a probability simplex on
a finite support, we define the most probable best (MPB) to be the solution
whose probability of being optimal is the largest. To devise an efficient
sampling algorithm to find the MPB, we first derive a lower bound to the large
deviation rate of the probability of falsely selecting the MPB, then formulate
an optimal computing budget allocation (OCBA) problem to find the optimal
static sampling ratios for all solution-input model pairs that maximize the
lower bound. We devise a series of sequential algorithms that apply
interpretable and computationally efficient sampling rules and prove their
sampling ratios achieve the optimality conditions for the OCBA problem as the
simulation budget increases. The algorithms are benchmarked against a
state-of-the-art sequential sampling algorithm designed for contextual ranking
and selection problems and demonstrated to have superior empirical performances
at finding the MPB
Dynamics and microstructure of colloidal complex fluids: a lattice Boltzmann study
The lattice Boltzmann (LB) method is a versatile way to model complex fluids
with hydrodynamic interactions through solving the Navier-Stokes equations. It is
well-known that the role of hydrodynamic interactions is ignorable in studying the
Boltzmann equilibrium of colloidal (Brownian) particles. However, full hydrodynamic
interactions play an important role in their dynamics. In the LB framework for moving
colloids, the “bounce-back on links” method is used to calculate the hydrodynamic
forces. In this thesis, three kinds of colloidal complex fluids with full hydrodynamic
interactions are simulated by lattice Boltzmann methods: colloids in a binary fluid,
magnetic colloids in a single fluid and magnetic colloids in a binary fluid.
First, we have done extensive simulations of nanoparticles in a binary fluid, following
up previous work[1] which predicted formation of a “bijel” (bicontinuous interfacially
jammed emulsion gel) in symmetric fluid quenches. Our work in this thesis focuses
on the analysis of the dynamics after nanoparticles become arrested on the fluid-fluid
interfaces under conditions varying from a symmetric quench to a strongly asymmetric
quench. Although these new simulations extend the time window studied by a factor
of two, slow domain growth is still observed. Our new analyses address the mechanics
of the slow residual dynamics which involves cooperative motion of the nanoparticles
at the fluid-fluid interfaces.
The second topic is the LB simulation of colloidal ferrofluids to see the effect
of full hydrodynamic interactions among magnetic colloids. The main focus is on
how the hydrodynamic interaction affects both the equilibrium dynamics of these
dipolar systems and also their transient dynamics to form clusters. Numerically,
magnetic colloids are implemented with the long-range dipolar interactions described
by Ewald summation. To check the effect of full hydrodynamic interactions, Brownian
dynamics without any hydrodynamic interaction has been done for comparison: Monte
Carlo results are also reported. We confirm that our LB generates the Boltzmann
distribution for static equilibrium properties, by comparison with these methods.
However, the equilibrium dynamics is altered: hydrodynamic interactions make the
structural relaxations slower in both the short-time and the long-time regime. This
slow relaxation rate is also found for transient motions.
The third topic addresses magnetic colloids in a binary fluid. In contrast with
the preceding two systems which correspond directly to laboratory experiments, this
last system is so far only predicted by the LB results in this thesis. To explore this
hypothetical new material by the LB method, the basic structures are investigated in
terms of both domain growth morphology and the arrangement of magnetic colloids.
Under conditions varying from a symmetric quench to an asymmetric quench, a
chainlike arrangement is observed for dipoles jammed on the surfaces, but the basic
morphology of domains is still maintained regardless of the dipolar strength. In
addition, applying external field affects the morphology of domains and the stability of domain structures
Usage-based construction grammar approach to Korean DO-causative constructions
This dissertation examined the two Korean DO-syntactic causatives, V-key HA and V-tolok HA, from a usage-based construction approach. Previous studies on the two DO-causatives have been heavily grounded in traditional or formalist grammar where the morphemes -key, -tolok, and HA were considered discrete elements, and the meaning of causation was limited to hypotheses about directedness. This dissertation takes the usage-based constructionist approach, treating V-key HA and V-tolok HA as individual constructions, pairing each form to its meaning. Also, this dissertation brings the cognitive linguistic notions of action chain and force dynamics to explore the semantics of the causative that the two constructions deliver in discourse. To answer questions about the synchronic usages of the two constructions and their relevance to the diachronic change of -key, -tolok, and their causative constructions, -key HA and -tolok HA, this dissertation explored both diachronic historical corpora and synchronic present-day corpora. The first part of the dissertation explored the semantic change of V-key and V-tolok and their development into the causative constructions, V-key HA and V-tolok HA from the 15th century to the early 20th century. The second part of the dissertation explored the synchronic usages of the two constructions in contemporary written newspaper corpora. The findings revealed that subjectification, pragmatic inferencing, metonymy, chunking, repetition, and habituation played key roles in semantic change and grammaticalization. The findings also showed the polysemous causative senses both constructions share and the distinctive central sense of each construction. The different event profiles each construction denotes trace back to the original semantics of V-key and V-tolok. This dissertation argues for the value of the usage-based constructionist approach to the study of competing constructions in Korean and the relevance of diachronic evidence in the analysis of contemporary constructions
Establishing a Content Taxonomy for the Coherent Study of Engineering in P-12 Schools
Engineering education has increasingly become an area of interest at the P-12 level, yet attempts to align engineering knowledge, skills, and habits to existing elementary and secondary educational programming have been parochial in nature (e.g., for a specific context, grade, or initiative). Consequently, a need exists to establish a coherent P-12 content framework for engineering teaching and learning, which would serve as both an epistemological foundation for the subject and a guide for the design of developmentally appropriate educational standards, performance expectations, learning progressions, and assessments. A comprehensive framework for P-12 engineering education would include a compelling rationale and vision for the inclusion of engineering as a compulsory subject, content organization for the dimensions of engineering literacy, and a plan for the realization of this vision. The absence of such a framework could yield inconsistency in authentically educating students in engineering. In response, this study was conducted to establish a taxonomy of concepts related to both engineering knowledge and practices to support the development of a P-12 curricular framework. A modified Delphi method and a series of focus groups—which included teachers, professors, industry professionals, and other relevant stakeholders—were used to reach a consensus on engineering concepts deemed appropriate for secondary study. As a result, a content taxonomy for knowledge and practices appropriate for P-12 engineering emerged through multiple rounds of refinement. This article details the efforts to develop this taxonomy, and discusses how it can be used for standards creation, curriculum development, assessment of learning, and teacher preparation
GaAs droplet quantum dots with nanometer-thin capping layer for plasmonic applications
We report on the growth and optical characterisation of droplet GaAs quantum
dots with extremely-thin (11 nm) capping layers. To achieve such result, an
internal thermal heating step is introduced during the growth and its role in
the morphological properties of the quantum dots obtained is investigated via
scanning electron and atomic force microscopy. Photoluminescence measurements
at cryogenic temperatures show optically stable, sharp and bright emission from
single quantum dots, at near-infrared wavelengths. Given the quality of their
optical properties and the proximity to the surface, such emitters are ideal
candidates for the investigation of near field effects, like the coupling to
plasmonic modes, in order to strongly control the directionality of the
emission and/or the spontaneous emission rate, crucial parameters for quantum
photonic applications.Comment: 1 pages, 3 figure

Theaflavin-3, 3\u27-digallate induces apoptosis and G2 cell cycle arrest through the Akt/MDM2/p53 pathway in cisplatin-resistant ovarian cancer A2780/CP70 cells
Ovarian cancer is the most lethal gynecological cancer among women worldwide. Adverse side effects and acquired resistance to conventional platinum based chemotherapy are major impediments in ovarian cancer treatment, and drive the development of more selective anticancer drugs that target cancer-specific defects. In this study, theaflavin-3, 3\u27-digallate (TF3), the major theaflavin monomer in black tea, exhibited a potent growth inhibitory effect on the cisplatinresistant ovarian cancer A2780/CP70 cells (IC50, 23.81 μM), and was less cytotoxic to a normal ovarian IOSE‑364 cells (IC50, 59.58 μM) than to the cancer cells. Flow cytometry analysis indicated that TF3 induced preferential apoptosis and G2 cell cycle arrest in A2780/CP70 cells with respect to IOSE‑364 cells. TF3 induced apoptosis through both the intrinsic and extrinsic apoptotic pathways, and caused G2 cell cycle arrest via cyclin B1 in A2780/CP70 cells. The p53 protein played an important role in TF3-induced apoptosis and G2 cell cycle arrest. TF3 might upregulate the p53 expression via the Akt/MDM2 pathway. Our findings help elucidate the mechanisms by which TF3 may contribute to the prevention and treatment of platinum-resistant ovarian cancer
