只有一小塊炸雞的營養午餐「太空虛」 福岡官員回應了
因物價漲不停，日本社群媒體上不時有網友曬出現寒酸相十足的營養午餐照，造成話題。而今年4月福岡一所小學的午餐主菜竟然只有一塊炸雞，引爆網友不滿，紛紛留言，「實在太少了」、「太空虛了」。《朝日新聞》採訪午餐負責人，得到令人意外的答案。
這張營養午餐照掀起話題，連從前吃過營養午餐的大人也議論紛紛。「期待營養午餐的人會不去上學了吧」，還有人稱他看了覺得很驚訝，問了念小學的女兒，女兒告訴他的確是如此。《朝日新聞》訪問福岡市教育委員會的營養午餐負責人。
福岡市教育委員會學校午餐營運課課長野原健表示：「確實，我們需要在外觀上多花點心思。」 不過，他表示，炸雞的規格是每塊約60克，熱量約155大卡，「大小大約相當於普通的兩塊炸雞」。他稱，福岡市從昭和時代開始就這麼做了。

The Log Periodic Antenna as known as LPDA is a wideband directional antenna that provides gain and directivity combined over a wide band of frequencies.
Both Log-Periodic Antennas and Yagi antennas are high gain directional antennas. The main difference between these antennas is that Log-Periodic Antennas support wider frequency bandwidths and are physically much larger than Yagi antennas.
The log-periodic dipole array typical VSWR is 2:1 and operates over a much wider bandwidth and will have a lower gain for an equivalent number of elements.
With this level of performance, it is ideal for many applications, although a log-periodic antenna will be much larger than a Yagi of an equivalent gain.
