Beginner in Game Development, Which Engine Should I Use? Comparison of Unity vs Unreal vs Godot (Focusing on Free Engines) Choosing a Game Engine: Know This First: 5 Key Q&A Q1. What is a Game Engine? Is it necessary to use one? A. Think of a game engine as a set of development tools that bundles essential functions required for making games, similar to a car engine. It includes features like rendering graphics on-screen ( Rendering ), physics effects for characters colliding with walls or jumping ( Physics Engine ), and playing background music or sound effects ( Audio System ). While it's possible to create a game from scratch without an engine, it requires an immense amount of time and effort, which is why most developers today use game engines, especially beginners! Q2. I want to start game development; are there any good free engines available? A. Yes,...
What Has Changed in the First 100 Days of Trump's Second Administration?
Trump's First 100 Days of the Second Administration: What Has Changed? (Summary of Immigration, Trade, and Education)
First 100 Days: Key Points to Know - 5 Essential Q&A
Q1. What changed first?
The most notable change is undoubtedly in immigration and border policy. On Inauguration Day (January 20), an executive order was signed to strengthen border control, and directives were issued to restore the 'Migrant Protection Protocols (MPP)' policy, bringing rapid changes.
Q2. What is the 'Liberation Day Tariff'?
This is a new tariff policy announced in early April. It imposes a 10% blanket tariff on almost all imported goods and adds 'reciprocal tariffs' on countries that create significant trade deficits for the U.S. It has had a major impact on the global supply chain.
Q3. What changes occurred in education, particularly regarding gender equality regulations?
The administration reversed the previous government's policies and returned to the 2020 regulations. The key change is applying gender based on 'biological sex' and strengthening the rights of respondents in sexual harassment investigations (such as face-to-face hearings).
Q4. How has climate policy changed?
Through an executive order named 'American Energy Liberation', the administration clearly indicated a direction towards deregulation by streamlining the oil and gas development process on federal lands. It also included measures to curb state climate policies by the federal government.
Q5. What has happened with support for Ukraine?
During the first 100 days, the support stance showed significant fluctuations. Military support was temporarily halted in March and partially lifted in connection with ceasefire discussions, leading to tensions with existing allies.
It has been a whirlwind 100 days. Since the official launch of Trump's second administration on January 20, 2025, the familiar yet intensified policy of 'America First' has enveloped Washington. Policies that were anticipated during the first administration (2017-2021) have begun to be reactivated at a much faster pace and broader scope this time. Especially with the concentrated use of 'presidential executive orders' that do not require congressional approval, immediate changes are appearing in nearly all areas of our lives, including immigration, trade, education, and energy. Today, we will examine what specifically has changed in key areas during the first 100 days of Trump's second administration (1/20-4/29).
What Has Changed: Summary by Key Areas
Changes during the first 100 days have been particularly notable in five areas.
1. Immigration and Border (Effective January 20)
The first area to see action was immigration policy. On Inauguration Day, an executive order was signed to resume the construction of physical barriers at the southern border and expand surveillance technology. Notably, the directive to restore the 'Migrant Protection Protocols (MPP)' policy indicated a much tougher stance on border policy compared to before.
2. Trade and Industry (April 'Liberation Day Tariff')
In early April, a package known as the 'Liberation Day Tariff' was announced, which has created tension in the global trade market. The two core aspects are: first, imposing a 10% basic tariff on almost all imports, and second, adding 'reciprocal tariffs' on countries that create trade deficits for the U.S. This has started to act as an immediate variable affecting global supply chains and consumer prices.
Episode: Michael, a Small Importer, Sighs
Michael, who runs a small business importing electronic components, is in a state of emergency due to the tariff announcement in April. "Even a 10% blanket tariff significantly increases our cost burden, and the Asian countries we mainly import from are being mentioned as targets for 'reciprocal tariffs.' I'm worried I might have to raise product prices starting in the second quarter, and I'm losing sleep over potential complaints from our clients."
3. Education and Gender Equality Regulations (Title IX)
There have also been significant changes in education. The regulations amended in 2024 prohibiting gender-based discrimination (Title IX) were repealed, reverting to the regulations from the Trump administration in 2020. As a result, the legal definition of 'gender' is applied based on 'biological sex', and the rights of respondents in campus sexual harassment investigations, such as face-to-face hearings and cross-examinations, have been strengthened again.
4. Energy, Climate, and Regulation
Through an executive order named 'American Energy Liberation', the administration has significantly simplified the approval process for oil and gas drilling on federal lands. Additionally, measures have been included to allow the federal government to intervene in state governments that pursue independent climate policies, signaling potential legal disputes ahead.
5. Foreign Policy (Ukraine and Atlantic Alliance)
Uncertainty has increased in relations with allies. Particularly in early March, there were moves to temporarily freeze military support for Ukraine in connection with 'ceasefire negotiations.' This caused significant friction with European allies who had been urging immediate support and has been viewed as causing cracks in the trust of the Atlantic alliance, which had anticipated America's return.
How It Works: Policy Mechanisms
The most significant feature of the first 100 days is the maximized use of 'executive orders', which can produce immediate effects without going through Congress. Additionally, the strategy of 'regulatory rollback'—reversing regulations set by the previous administration through administrative guidelines or reinterpretations—has been particularly prominent in education and energy sectors. In trade, tariffs have been enforced rapidly based on powers delegated to the president, such as the Trade Expansion Act.
What Remains: Controversies and Challenges
Whether these pushed policies can continue to sail smoothly remains uncertain. Education, immigration, and environmental policies are already facing lawsuits from several state governments and civic groups, making the sustainability of these policies ultimately dependent on judicial rulings. Additionally, while the 10% blanket tariff may revive U.S. manufacturing, it poses a dilemma of potentially raising consumer prices and provoking retaliatory tariffs from allied countries.
In-Depth Exploration 1: What is the 'Liberation Day Tariff' and Why is it Important?
The 'Liberation Day Tariff', announced in early April, symbolically represents the protectionist stance of Trump's second administration. This policy is divided into two main parts. The first is the '10% universal tariff', which imposes a 10% basic tariff on almost all goods imported into the U.S., regardless of whether they come from allied countries. This directly contradicts the free trade system that has been in place since World War II and can directly impact consumer prices in the U.S.
The second part is the 'reciprocal tariff'. This targets countries that create trade surpluses with the U.S., meaning countries that buy more from the U.S. than they sell. If a counterpart country imposes a 25% tariff on U.S. products, the U.S. would impose the same 25% tariff on their products, following a 'tit for tat' approach. This is a powerful card that could lead to an all-out trade war with major trading partners such as China, the European Union, and Mexico, capturing global attention.
In-Depth Exploration 2: How Do Changes to Title IX Regulations Affect Campuses?
In U.S. education policy, 'Title IX' is a 1972 law that prohibits gender-based discrimination in educational institutions receiving federal funding. The 'interpretation' of this law has been one of the most contentious issues with each change of administration.
The Trump administration repealed the regulations amended in 2024 (which broadly recognized gender identity and the rights of transgender students) and reverted to the regulations created during their first term in 2020. The core of the 2020 regulations includes two main points. First, it strongly tends to define 'sex' as 'biological sex'. Second, it mandates the rights to face-to-face hearings and cross-examinations for respondents under the pretext of ensuring equal rights for both complainants and respondents during investigations of sexual harassment or violence on campus. This provision, criticized by victim advocacy groups for potentially causing secondary harm to victims, has led universities and school districts across the U.S. to face confusion as they must completely revise related policies and procedures due to the revival of this regulation.
Episode: Sarah's Concerns as a University Administrator
Sarah (a pseudonym), who works at a university's gender equality center, is working overtime due to the changes in Title IX regulations. "We have to revert all procedures and policy manuals back to the 2020 version in just one year. To avoid confusing students, we need to update all guidance materials and retrain investigators on the new procedures. Above all, I'm most worried that students who have bravely come forward may hesitate to report because of the strengthened face-to-face hearing procedures."
Q. What should export/import/procurement personnel check?
They should confirm the exact list of items subject to the 'Liberation Day Tariff' (HS codes) that came into effect on April 5 and 9 and immediately reassess how much the cost increase will be. Additionally, they should review the proportion of imports from countries mentioned as targets for 'reciprocal tariffs' and prepare a supply chain diversification strategy.
Q. What should university or school district personnel prepare?
They need to immediately update internal policies, student training manuals, and investigation procedures to align with the 2020 Title IX regulations. It is essential to prepare for fair operations of face-to-face hearings and cross-examinations, while also reviewing for any conflicts between state laws and the new federal regulations.
Q. What opportunities and risks exist for energy/manufacturing personnel?
With the simplification of federal government approval processes, there is an opportunity to reassess the pipeline of projects that have been delayed. However, even if the federal government relaxes regulations, there is a risk of conflicts arising as state governments may oppose, so it is advisable to reflect this policy uncertainty in contracts or insurance.
