万分沮丧之下,他发明了可以允许自拍的东西:他称之为"伸缩杆"。因为智能手机还没发明出来,所以,连接在自拍杆末端的是一个微型相机。在杆的前端有一面小镜子,方便使用者调整他们在相机里的姿态。他在1983年为"伸缩杆"申请了专利。虽然自拍杆进行了大量生产出售,却属商业败笔——相片的质量比较差。另外,以前的研究表明,那时的女士会因自己有自拍的想法而感到尴尬。在2000年,自拍杆被韦恩·弗洛姆(Wayne Fromm)重新发明,那时,上田宏的"伸缩杆"专利期尚有三年。弗洛姆称他的自拍杆为"快捷豆荚"。他认为他才是当今自拍杆的发明者,甚至起诉其他自拍杆生产者。当被问到上田宏的自拍杆时,弗洛姆评论说它们是"先前的艺术"。
"We are quite interested in looking at China's efforts and experience in combating corruption. It's a problem we are faced with in South Africa, and one we are tackling with a lot of vigor.Recently, the South African government introduced new measures to combat corruption. This is interesting, because it was immediately after a visit by our minister for public services, who met with the minister here who is responsible for anti-corruption measures.So this is one of the examples of the usefulness of this interaction between our leadership and the leadership of the People's Republic of China."

Pregnancy symptoms during week 4

No symptoms?

Don't worry. Many women don't feel anything yet this week. In fact, most early pregnancy symptoms don't start until about 6 weeks.

Tender, swollen breasts

Breast tenderness can be one of the earliest signs of pregnancy. It usually starts around 4 to 6 weeks and lasts through the first trimester.

Fatigue

For many women, exhaustion is one of the first signs of pregnancy. But other women hardly seem to slow down at all.

Nausea or vomiting

Morning sickness can strike at any time of day. It usually starts around 6 weeks of pregnancy but can begin as early as 4 weeks. Some women have cramping as well.

Pregnancy checklist at 4 weeks pregnant

Take a pregnancy test

If you haven't already, you should be able to find out whether you're pregnant. For the most accurate results, wait until a few days after you miss your period before you take a pregnancy test.

Make a prenatal appointment

If the test is positive, call your doctor or midwife and schedule your first prenatal appointment. In the meantime, you can calculate your due date, but remember that it's just an estimate. You're just as likely to go into labor any day during the two weeks before or after.
