Individuals rely on Theory of Mind (ToM) to represent themselves, others, and socio-cultural norms. Distinctive Western and Eastern developmental patterns of ToM have been reported in monocultural children. Relatively little is known about bicultural children, especially those children who grow up in two conflicting and unbalanced cultures. We hypothesized that the development of ToM in these bicultural preschoolers would follow the pattern of the dominant culture. To examine this hypothesis, we recruited English-speaking Chinese Singaporean preschoolers. In Study 1, we tested 3- to 5-year-olds (N = 120) with 5 ToM tasks, including diverse desires, diverse beliefs, knowledge access, and false belief, as well as a vocabulary task. In Study 2, we tested 5-year-olds (N = 30) with a picture-choice version of these ToM tasks. Both studies supported our hypothesis by revealing that the development of ToM in these bicultural children followed the pattern of the dominant culture. Additionally, we found that 5-year-old bicultural children are still developing false belief, and their verbal ability correlated with their ToM.

The Electric Power Subsystem (EPS) is one of the most critical systems on any satellite because nearly every subsystem requires power. This makes the choice of power systems the most important task facing satellite designers. The main purpose of the Satellite EPS is to provide continuous, regulated and conditioned power to all the satellite subsystems. It has to withstand radiation, thermal cycling and vacuums in hostile space environments, as well as subsystem degradation over time. The EPS power characteristics are determined by both the parameters of the system itself and by the satellite orbit. After satellite separation from the launch vehicle (LV) to its orbit, in almost all situations, the satellite subsystems (attitude determination and control, communication and onboard computer and data handling (OBC&DH)), take their needed power from a storage battery (SB) and solar arrays (SA) besides the consumed power in the EPS management device. At this point (separation point, detumbling mode), the satellite's angular motion is high and the orientation of the solar arrays, with respect to the Sun, will change in a non-uniform way, so the amount of power generated by the solar arrays will be affected. The objective of this research is to select satellite EPS component types, to estimate solar array illumination parameters and to determine the efficiency of solar arrays during both detumbling and normal operation modes.

Objective: The aim of this study is to investigate the effect of Hangul font on reading speed when texts are displayed on the computer screen. Background: Reading performance is influenced by fonts. However, there are few studies of Hangul font from a cognitive perspective. Fonts could affect reading performance directly and indirectly, interacting with other visual-perceptual factors such as size, word spacing, and line spacing. Method: In experiment 1, two variables were manipulated; a frame condition(square frame non-square frame) and a stroke condition(serif sans-serif). According to each condition, one of the four fonts was applied to the texts. The height of the four fonts was controlled. The participants were asked to read aloud the presented texts. In experiment 2, the non-square frame fonts were adjusted to have approximately the same size, width, letter spacing, and word spacing as the square frame fonts. The experimental design and task used in experiment 2 were identical with experiment 1. Results: In general, reading speed was faster in the square frame fonts than in the non-square frame fonts. The reading speed was not significantly different across stroke conditions. Conclusion: The frame of Hangul font significantly influenced reading speed. These results suggest that the type of Hangul font is a factor to affect reading performance. Application: The frame of fonts should be considered in designing of new fonts. The square frame fonts should be the preferred choice to enhance legibility.

In early Highlighting the client's personality especially, home design demands very careful consideration. It's not an easy task to understand the characteristics of each family member, to take into account their requirements, and strike proper harmony among them. For this Sampung Apartment Project, I decided to create a cozy homelike atmosphere by using overall modern and antique furniture, props, and lighting. I tried a different sense of space by choosing wood as the main material, installing furniture that looked antique, and applying painting with touch instead of pictures or wallpaper By the use of the light bulb color overall, lighting was yellow and added more comfort. Local lighting was used in certain places to add more fun along with the props. After choosing white as the main color, point colors were determined according to the client's inclination toward green and blue. The color choice also matched the client's paintings that were in soft green and blue. Each room was planned and color coordinated according to their own characteristics. The children's rooms were planned with such point colors as pink, green, and blue. The master bedroom and the family room were produced around gold and grey color, respectively.

In this investigation, turbulent premixed combustion and flame front propagation in a gas turbine combustion chamber is studied. Direct numerical simulation of turbulent reacting flows demands extremely high computational resources, especially in more complicated geometry. The alternative choice may be left for Large Eddy Simulation (LES) by which only large scales are solved directly. In combustion problems, capturing the large scales' behavior without solving the details of small scales is a difficult task. Using a transport equation for description of the flame front propagation and therefore avoiding the calculation of inner flame structure is the basic idea of this study. For this purpose. the so-called G-equation has been used by which any iso-level of the G variable provides the flame location. A comparison with the experiment indicates that the present method can predict a turbulent velocity field and also capture a instantaneous 3-dimensional flame structure.

There are currently three common methods for selecting excavation supports in Polish hard coal mines. While many factors are considered when choosing appropriate support, these do not include layering or cracking in the excavation ceiling. Although global classifications of rock mass are rarely used in hard coal mines, they are utilised much more frequently during the construction of underground structures such as tunnels. Mining classifications of rock mass have been developed (e.g., in Germany) and they rely on a number of factors but are often related to local mining and geological conditions. This paper discusses the selected findings of a study carried out on seven excavation sites with diverse mining and geological characteristics. Based on the collected data, two indicators were developed to describe rock mass quality. The first indicator is referred to as the roof lithology index WL and describes the quality of the excavation roof in terms of its layering and lithology. The second indicator is the crack intensity factor n and represents the amount of cracks in an excavation's roof. The correctness of the developed indicators was supported by reliable data from the excavation in which the designed support did not fulfill its task but was changed at a later stage, after calculating the proposed indicators.

Objective : The aim of this study was to investigate effects of Gagambosim-Tang(GBT) of focal brain ischemic injury induced by intraluminal filament insertion in the rats. Method : The ischemia was induced by intraluminal filament insertion into middle cerebral artery Eight-arm radial maze was designed for the behavioral task. Gagambosim-Tang was orally administrated in SD rats for 21 days. The task was started on the 4th week after focal brain injury, and performed two trials per day for 6days. The effects of Gagambosim-Tang on neuroprotective agents in cresyl violet, choline acetyltranferase(ChAT), nerve growth factor (NGF)-stain and c-Fos with ischemic injury were investigated. Results : The errors in the eight-arm radial maze task were significantly decreased in normal group compared with control group on 2-6days, GBT lX(42.2 mg/ml)orally administrated group on 1days, GBT 6X(253.2 mg/ml) on 3, 5, 6days. The rate of correct choice was increased in normal and GBT 6X groups. The neuroprotective effect in the hippocampal CA1 was increased in normal and GBT 1X, GBT 6X groups compared with control group. The density of ChAT in the hippocampal CA1 was increased in normal and GBT6X groups compared with control group. The density of NGF in the hippocampal CA1 was increased normal and GBT6X groups compared with control group. The number of c-Fos-positive neurons in the hippocampal CA1 was increased in normal and GBT 6X groups compared with control group. Conclusion : These results suggest that Gagambosim-Tang may have protective effect on dementia.

The purpose of the study is to examine sports-related cognitive functions through a systematic review and to suggest effective instruments to measure the cognitive functions. The present study was conducted based on the systematic review and meta-analysis protocol-the PRISMA. Of 429 articles searched through keywords from 2008 to 2020, 45 articles that met the selection criteria were analyzed. It was revealed that athletes had better cognitive functions than non-athletes, that the higher the sports expertise was, the higher the cognitive functions, and that there were differences in cognitive functions according to the sport types. The primary cognitive functions related to sports performance summarized as executive functions (inhibition ability, cognitive flexibility), information processing speed, spatial ability, and attention. As tasks for measuring each cognitive function, a stop signal task for inhibition ability, a design flexibility task for cognitive flexibility, a simple and choice reaction time test for information processing, a mental rotation task for spatial ability, and an attention network test for attention are appropriate.

A conflict of interest (COI) places people in ethical dilemma when providing consultation in a field of business, medical/pharmaceutical industry, research etc. Disclosure is a commonly adopted strategy for the adverse effect of COI, but previous studies have reported inconsistent results. This investigated whether individual differences in pursuing self-interest influence differently on consultation behavior during voluntary- or no-disclosure of COI conditions. A total of 190 adults participated in an on-line experiment which consisted of two tasks. On the 1^st task, participants were divided into either a role-oriented group or a self-interest group depending on their consultation choice on the task. On the 2^nd task, participants were required to choose whether to disclose COI to his/her virtual partner and provided consultation to them. No group differences were found in frequency of choosing voluntary disclosure. For the role-oriented group, the voluntary disclosure group provided unbiased information to the virtual partners than the no disclosure group. However, no group difference between voluntary- and no-disclosure group in the self-interest group. Implications and limitations are further discussed.

The major purpose of this article is to examine what kind of gap exists between mathematically gifted students' probability knowledge and the reality actually applying that knowledge and then analyze the cause of the gap. To attain the goal, 23 elementary mathematically gifted students at the highest level from G region were provided with problem situations internalizing a probability and expectation, and the problems are in series in which conditions change one by one. The study task is in a gaming situation where there can be the most reasonable answer mathematically, but the choice may differ by how much they consider a certain condition. To collect data, the students' individual worksheets are collected, and all the class procedures are recorded with a camcorder, and the researcher writes a class observation report. The biggest reason why the students do not make a decision solely based on their own mathematical knowledge is because of 'impracticality', one of the properties of probability, that in reality, all things are not realized according to the mathematical calculation and are impossible to be anticipated and also their own psychological disposition to 'avoid loss' about their entry fee paid. In order to provide desirable probability education, we should not be limited to having learners master probability knowledge included in the textbook by solving the problems based on algorithmic knowledge but provide them with plenty of experience to apply probabilistic inference with which they should make their own choice in diverse situations having context.
