How can we improve the efficiency of information gathering?

Information gathering in an age of information overload. The sheer volume of information itself, but also the diversity of information-gathering methods, makes it difficult to know how to collect information efficiently. Decide when to collect information. Browse in print in a timeline format: broadly and shallowly → deeply and narrowly. Hit primary information as much as possible or narrow down who to focus on.

[Sublingual immunotherapy] Why can’t Cidacure be held under the tongue for 1 minute and then gargled for 5 minutes before eating or drinking?

Cidacure is a sublingual allergen immunotherapy for allergic rhinitis caused by cedar pollen. The dose is 2,000 JAU tablets for the first week and 5,000 JAU tablets for the second and subsequent weeks. Cidacure currently has limited shipments of 2,000 JAU tablets, and some patients who want sublingual immunisation may not be able to start due to lack of stock.

[Mia] Simulate every step of the packing process.

ちなみに最初の100台の組み立てに関しては、手作業で自分達で行うことにした。コストカットと、自分達が全工程を把握していないと、次の量産の段階でも明確な指示が出せないので。今回使用するTTP223タッチセンサーは、100個セットで届いているので1つずつに分解して、ピンヘッダーをハンダする必要がある。ひたすらハンダしていく。

[ISFP] Adventurer. Introverted Emotional Type with a Sense of Extroversion (MBTI)

The ISFP is a cognitive function of the Fi-Se, so it makes decisions based on its own feelings and values from information obtained through the five senses. Although they tend to conform to their surroundings because they don't want to get into conflict with others because it is troublesome, they have the image of being free-spirited artists and having a seemingly contradictory state of being at their own pace.

[Thinking Fitness] How do you train yourself to keep thinking instead of thinking?

Of course, being to the point, having a quick mind and being able to concentrate at a moment's notice are important, but only up to the upper middle level. From there onwards, the people will be at the same level as the above base, so I personally think that the two factors of 'health' and 'thinking stamina' make the difference.
