Swimming pools adopt strategies to keep water cool

2024-07-19

In the summer heat, swimming is a fun way to cool off. But if you head to an outdoor pool, you might feel like you’re still getting sunburned as you swim. Some people prefer an indoor pool, while others want a refreshing natural breeze outside. Pools adopt various different strategies to keep the water as cool as possible. Let’s take a look at some of the options.

Let’s face it: it’s hot. Lots of us are heading to pools to beat the heat.

But with the mercury this high, you’re not just in danger of sunburn. Even the water in an outdoor pool is heating up uncomfortably. That leads many to choose an indoor pool.

Some want to avoid direct sunlight. Others feel cooler in an outdoor pool and think indoor venues get stuffy.

They’re all quite cool. The only place you’d get hot is if you spend the whole time out of the water, at the side, not swimming. But normally I think it’s fine. If you’re circulating it’s fine.

The temperature in an unshaded outdoor pool will normally rise to between 28 and 32 degrees Celsius. Many companies add shade nets to bring the temperature down a couple of degrees or more.

On the one hand, we use the shade nets if we want to lower the temperature. On the other hand, we use tap water which also lowers the temperature.

Apart from the shade facilities, pools also constantly circulate fresh water which keeps it cool. You wouldn’t want a swim to feel like a dip in the hot spring.

熱! 運動中心泳池人數暴增不斷換水控溫30度以下

2024-07-19

夏天到了，民眾會去游泳消暑，不過，炙熱的陽光曝曬下，連游泳池的水溫，也跟著升高，就有不少民眾，選擇到室內運動，以新北市15座國民運動的室內泳池來說，入場人次就增加不少。至於室外的游泳池，為了不讓民眾游泳像在泡溫泉，除了不斷換水降溫，也會增設遮陽的網罩，把水溫控制在28度到30度上下。

從滑水道高速溜下，小朋友笑聲此起彼落，玩得好開心。

天氣實在太熱，許多民眾乾脆來游池，游泳消暑。

不過，太陽實在好大，別說人要被曬傷、烤焦了，就連泳池裡的水溫，也跟著飆升，就有不少民眾，選擇室內的游泳池。

有人不想曬太陽，但也有很多泳客覺得戶外才涼爽，室內游泳池好悶熱。

[[民眾]]
“都是蠻涼的啦，除非是室外一直都是在那種外面，或是邊邊都沒有人在玩的，可能一直在那邊曬才有可能，像平常我覺得這種都還好，有在循環都還好。”

一般室外游泳池，若沒有遮蔽物，水溫大概落在28到32度，許多業者都有加裝遮陽網罩，水溫就能下降至少2度，甚至更多。

[[運動公園泳池救生員]]
“一方面我們降溫的話，我們用遮陽網降溫，另外一方面我們用自來水，用自來水來降溫。”

除了遮陽的設備，泳池還會不斷換水降溫，不讓民眾游泳像是在泡溫泉。

Trump’s remarks provoke talk of raising Taiwan’s defense budget

Remarks made by U.S. presidential candidate Donald Trump that Taiwan should pay the U.S. for defense have sent shockwaves across the island. In the latest, Robert O’Brien, who served as national security advisor under Trump said he believed his former boss meant that he wanted Taiwan to contribute more to its own defense, and even raise its military expenditures to 5% of the GDP. Looking at Taiwan’s 2024 defense budget of NT$606.8 billion, it only stands at 2.5% of the GDP. In contrast, other nations that are threatened by their neighbors such as Korea and Israel spend 2.8% and 5% respectively. One leading military scholar says Taiwan still has room to increase its military spending.

Robert O’Brien (2023)
Former White House National Security Advisor
We’ve got 18 billion dollars of arms sales approved for Taiwan and we need to get those systems delivered now and not wait for them.

Robert O’Brien, who served as national security advisor under former president Donald Trump, visited Taiwan last year, where he stressed that arms sales projects with Taiwan should not be delayed. Recently, Trump said that Taiwan should pay the U.S. for defense. O’Brien interprets this to mean Trump thinks Taiwan should make more fiscal contributions to its own defense. O’Brien believes the free world is now aware of China’s threat and Taiwan should consider increasing its defense spending to at least 5% of its GDP.

Taiwan’s annual defense budget has actually been increasing incrementally over recent years. It started out at NT$349.7 billion in 2016, NT$355.7 billion in 2017, and exceeded NT$400 billion in 2020. Last year, it soared to NT$580.3 billion and this year it hit a new high of NT$606.8 billion. Taiwan’s defense spending as a proportion of its GDP has increased from a previous 2% to 2.5% this year.

However, military analysts still believe that compared with other nations that are threatened by neighboring countries, such as Israel and South Korea, Taiwan’s defense budget indeed has more room for growth.

Su Tzu-yun
Institute for National Defense and Security Research
In the international community, there is a very important thing: all for one, one for all. It’s also if I help myself, others will help me. Compared with other countries facing threats, such as Israel, its defense budget is 5% of GDP, Singapore’s stands at 3% and South Korea’s is between 2.8% and 2.9%. This shows that our own defense budget indeed still has room for a reasonable increase. Trump’s so-called charging Taiwan insurance fees and alleging that Taiwan steals America’s chip business may be an oversimplification. What he should be talking about is the responsibilities for allies for self-defense.

Since former president Tsai Ing-wen took office in 2016, each year there had been no shortage of major arms purchases from the U.S. Many in U.S. political circles reckon that if Trump returns to the White House, there is a high chance that O’Brien will return as White House national security advisor. This is bound to affect the direction of Taiwan-U.S. arms deals.

Five year survey on immigrants in Taiwan finds 92.1% of them are happy with their lives

Today, the Ministry of Interior held a press conference to announce the results of a national survey on the living needs of immigrants. It turned out that more than 92% of new immigrants felt happy in Taiwan. One such happy new resident is a Singaporean national who is running a thriving coffee shop in New Taipei.

Ming Kai Lua
Singaporean immigrant
Actually many people will ask me, why do you want to settle in Taiwan? I think this question is like a young couple asking each other, what’s the thing you really love about me? When this happens, of course you have to answer, of course it’s everything.

Taiwanese immigrant Ming Kai Lua came to Taiwan from Singapore five years ago. Not only has he settled down in Taiwan, but he’s also opened up a cafe. Along the way, in addition to feeling the warmth of Taiwanese people, he also wants to thank the government for doing its utmost to care for new immigrants.

Ming Kai Lua
Singaporean immigrant
I think the most important thing is that everyone here respects different voices and ideas. I think this is something that touches me very much.

Liu Shyh-fang
Minister of the Interior
I have told many foreign friends that coming to Taiwan is not just tourism and travel. Taiwan is a treasure island. We hope that in Taiwan you can live here often or permanently or that even your children can become genuine new Taiwanese in Taiwan.

The Ministry of Interior held a press conference to announce the results of a five-yearly national survey on the living needs of new immigrants. The number of people who have immigrated to Taiwan through marriage has reached nearly 600,000. The overall labor participation rate is 75%, which is significantly higher than the 59.2% of Taiwanese. As much as 94.8% of immigrants were satisfied with their current jobs, and 92.1% were very happy with their life in Taiwan.

Liu Shyh-fang
Minister of the Interior
For current immigrants, of course the main important issue is their rights and interests. But in the future, if they plan to become Republic of China nationals, there are other laws involved, such as the Act Governing Relations between the People of the Taiwan Area and the Mainland Area.

Recently the TPP and KMT took advantage of their parliamentary majority to pass a “special law for new residents.” Observers have voiced concerns that lumping together Chinese spouses and immigrants from other areas could erode laws governing cross-strait relations. Regarding these concerns, Liu said that their naturalization would still be subject to existing laws governing cross-strait relations.

Okinawan marching band delights crowds with flash performance at Taipei 101

A marching band from Okinawa gave a sneak preview at Taipei 101 of their upcoming concert. They were the young musicians from Nishihara Senior High, who have been invited to perform at the Presidential Office Concert on Saturday evening at Liberty Square. The flash performance attracted a sizeable crowd who braved the scorching sun to enjoy the show.

Seventy-one young musicians from Nishihara Senior High School in Okinawa are here at Taipei 101 for a flash show.

Even under the scorching sun, they play their instruments with a broad smile. Among the audience were members of Taipei First Girls’ High School marching band, which previously performed with Japan’s Orange Devils. They had only praise for the performers.

Student
Taipei First Girls’ High School
I’m in the marching band, I play the French horn. They are all super nice, and put feeling into it. It makes for a very enjoyable performance you can immerse yourself in.

Student
Taipei First Girls’ High School
They are really enjoying it, their smiles are full of energy. When you smile back at them, they give you an even brighter smile in return. I can feel a sense of hope from their performance.

The Okinawan marching band has won many contests in Japan, and even clinched a championship title at the World Music Competition in the Netherlands. This time, the school is bringing a taste of Okinawa to Taiwan, with formations and transitions that allow Taiwanese audiences to feel closer to the performers. Many people came to the site early to secure a spot to watch the flash show.

Audience member
It’s adorable. They are so nice! The performance is lovely, super cute.

Audience member
We came early. Of course seeing the performance in person is something else. It was great. We’re going to go to Yuanshan to catch the other flash show. We tried to speak with them in broken Japanese and we took photos together!

The marching band is in Taiwan at the invite of the General Association of Chinese Culture, to perform at the Presidential Office Concert on Saturday evening, joined by the cheerleading squad from Shih Hsin University. Their moving music will bring together the people of Taiwan and Japan, while celebrating Taiwan’s Olympic team.

Program in Indonesia helps refugees from Asia and Africa resettle

Indonesia has become a temporary home for thousands of refugees from Asia and Africa. Voice of America’s Dave Grunebaum reports from Cisarua [chi-sa-ROO-ah], Indonesia, on a program that helps these displaced people prepare for the lives that lie ahead of them.

In these classrooms in Cisarua, Indonesia, 85 young refugees learn subjects from science to English to math.

Academically qualified students can even join an online program and work towards a U.S. high school diploma. It’s happening at the Cisarua Refugee Learning Center. Cisaura is a few hours drive from Indonesia’s biggest city, Jakarta, and hosts about 1,300 refugees, according to the United Nations refugee agency.

Afnaan Guleid is a 13-year-old whose family fled Somalia. She says her family worried about violence back in their homeland. But here, she can focus on her dreams.

Afnaan Guleid
Student refugee from Somalia
I want to be a scientist when I grow up because I love to do experiments and discover things by myself.

The facilities are very basic. This learning center is funded entirely from private donations, mostly from international donors. All of the teachers are volunteers, and many are refugees themselves. Students and their families fled violence or persecution in countries in Asia and Africa.

Reza Hussa
Learning center principal
Students from different cultures. Students from different religions. Students from different countries. When they come here, I’m sure there is a diversity of culture here.

Zahra Sakhawat is a 12-year-old student from Afghanistan. She says this learning center builds a sense of community.

Zahra Sakhawat
Student refugee from Afghanistan
The community is very good because everyone is very kind and dear with each other.

The United Nations refugee agency says that currently, the United States, Canada, Australia and New Zealand are accepting refugees who are staying in Indonesia but the process typically takes at least seven years and placement is not guaranteed. While Indonesia allows refugees to enroll in public schools, the Cisarua Refugee Learning Center offers its students a chance to focus on their English which is a skill they’ll need if they’re resettled.

Reza Hussa
Learning center principal
We are trying to prepare them for the next country that they are going.

The Cisarua Refugee Learning Center opened a decade ago and has become a model for similar refugee programs that have started elsewhere in the country to help young refugees prepare for the future.
