陳其邁說明,目前高雄仍處於疫情高原期,下週將可望逐漸趨緩。而在社區傳播風險下,市府採取早期診斷、早期治療策略,將持續撥補快篩試劑給高風險場域,以儘早篩出隱藏確診個案。
他指出,目前兒童疫苗覆蓋率已達77%,本週可達80%目標,呼籲民眾應儘速接種疫苗,並透過快篩及戴口罩、勤洗手等公衛手段,降低傳播風險,等疫情高原期過後,就可逐漸恢復正常生活。
教育局說明,居家遠距教學期間,補習班以線上教學為主,可視家長需求採混成教學方式(線上線下同步教學),另學校經防疫專責小組決議,可安排學生返校進行實體學習及活動(如期末考、團體訓練等),也可彈性調整定期及平時評量次數及比例,或採多元方式進行。
Precision Sleeve Dipole Antenna
Sort by:Select
Precision Sleeve Dipoles are omnidirectional antennas with a low VSWR and an electric dipole pattern that resembles a half-wave resonant dipole. The antenna can be end-fed thanks to the sleeve dipole design, which eliminates cable and feed point interactions that can degrade antenna performance and reduce cable interaction.
Applications:
- SL-800-SF-V2, 700 MHz to 900 MHz Band Omni Directional antenna
- Gain reference, low gain antenna efficiency reference, and chamber reflectivity evaluation
Features:
- Superior performance
- Lightweight
- Good appearance design
- Precision Gain for Range Calibration
- Avoid interfering with the antenna's effectiveness by avoiding cable and feed point contacts.
- (CTIA) +/- 0.1 dB symmetry requirement for ripple test measurements.

此外,國、高中疫苗施打如期舉行,呼籲家長鼓勵學童回校施打。高雄市流行疫情指揮中心表示,從疫苗涵蓋率及盛行率推估,20-39歲群體免疫效果已經顯現,高原期過後,疫情將逐漸趨緩。目前醫院負壓及專責病房空床率51%,加強型防疫旅館空床率89.5%,居家照護人數67,372人,醫療量能尚屬充足。
為鼓勵長輩及早接種疫苗,6/30前,65歲長輩(含55歲以上原住民)接種疫苗可獲2劑快篩試劑;完成1-4劑可得500元禮券,而設籍本市長輩完成第3、4劑加發200元禮券。5-11歲、64歲以上疫苗接種特別診,市府疫苗預約網站已開放預約,請市民朋友多加利用。(圖/高市府 提供)
