The possibility of partial breakthrough

Beyond the tactical level, to strategic level - health care IT in the local face of such opportunities.

Tranquil compared to 2005, medical information that is shown at the beginning of 2006 is different. Cite several developments recently learned that as evidence.

First, the number of hospitals selected to begin soon. According to the PLA General Logistics Department, Ministry of Health Information Center, Renning Yi said, follow the trend of medical and health system reform, the General Logistics Department Ministry of Health, Ministry of Health will jointly launch the digital hospital in the year were selected. This work is not a castle in the air. Medical and health information after the SARS epidemic in 2003, the parties have caused food for thought, since then, the digital hospital of the pilot and report to work on the agenda of local and which were carried out. General Logistics Department is in the end of 2003 the Ministry of Health held a military base in health information technology, building workshops. At that meeting, many military hospitals have put in the digital hospital building as its target. Nearly three years in the past, people understand the digital hospital may be more abundant and more diverse point of view, at least from a technical point of view beyond the original interpretation of the "three noes" (no paper, no film, radio) feature. In deepening the public's expectations of medical system reform, and business, management, medical IT is closely related to naturally take responsibility. Therefore, health care IT will be more and more problems with the medical system directly linked to the origin.

Second, health information standards being finalized. Absence of medical and health information standards, is constrained at the operational level health IT to promote the cause of the most important factor overall. The end of 2003, after weighing the same, the Ministry of Health lead the national health information standards organization launched the formulation. As a major issue, focused on the country field of medical and health information crack, were to carry out the overall framework of health information, hospital data collection standards, public health (including maternal and child health) information standard-setting. April 2004 Health Information Association of China established the professional standards committee is to break the boundaries of the previous sector to achieve the medical, health, social security, information industry and other expert resources to integrate the relevant departments to ensure the availability of standards.

Third, promote the Association building. A month ago, Beijing Union Medical College Hospital should include Director of Information Center, Li's invitation, I had the privilege to participate in the information the Chinese Hospital Management Association Professional Committee (CHIMA) held the first Spring Festival activities. Activities gathered from the military and the local hospital information technology experts and the backbone line.鏈娲诲姩鏄腑鍗庡尰闄㈢鐞嗗浼氫俊鎭鐞嗕笓涓氬鍛樹細鐨勨?鏈?悗涓?鈥濇椿鍔紝鍥犱负涓崕鍖婚櫌绠＄悊瀛︿細灏嗘寮忔洿鍚嶄负涓浗鍖婚櫌鍗忎細锛屼腑鍗庡尰闄㈢鐞嗗浼氫俊鎭鐞嗕笓涓氬鍛樹細涔熷皢闅忎箣鏇村悕涓轰腑鍥藉尰闄㈠崗浼氫俊鎭鐞嗕笓涓氬鍛樹細锛屽悕绉扮殑鏇存敼灏嗕細涓哄浼氱殑杩涗竴姝ュ彂灞曟彁渚涙洿鍔犲箍闃旂殑绌洪棿銆?br />

Serial ATA and SCSI rematch

Magic pirates Road ridge - ATA and Serial SCSI rematch





Speaking from the application level, ATA and SCSI is much larger than complementary relationship between competition and compete with the existing value should be no distinction; But if tapping the technical details of what what the weak strong, the discussion of precedence is not no significance.

History: Winning the basis of

The advent of SCSI earlier than ATA, specifications and more perfect, but it does not mean that the application of new technologies is always walking in front of SCSI. This more typical example is the double along the transmission (DT, principle equivalent to DDR) and the CRC checking, introduced in 1996, Ultra ATA/33 (also known as Ultra DMA/33) already in place, a full two years earlier than the SCSI (Ultra3 SCSI).

Some features are equally matched. Still CRC checksum, for example, initially only the data with (Data Phase) to enjoy this treatment, then ATA and SCSI invariably be enhanced to include command and status on all transfers, including content protection (below) - from standard setting to the product of, Serial ATA 1.0 and Ultra320 SCSI are almost the same in time.



CRC-wide changes

However, the basic underlying framework, inherent in the ATA how hard they try to shrink the gap with SCSI. LVD (Low Voltage Differential, low-voltage differential), an uncomplicated but requires double data lines (transmission, respectively positive and negative voltage signal) technology, a decision SCSI and parallel ATA (Parallel ATA, PATA) for development important factors. LVD enhanced signal interference, anti-fading ability, help to extend the connection distance, to ensure the reliability of high-frequency transmission. LVD's point of view standing problem, it is easy to understand why SCSI do not rush to adopt the double along the transmission and the CRC checksum.

If you do not use double along the transmission, PATA to achieve 33MB / s bandwidth, operating frequency will reach 16.6MHz, but PATA's 40 data lines when the operating frequency approximation 11.1MHz had not guarantee transmission quality, while the double along the transmission to Ultra ATA/33 without raising operating frequency (8.3MHz) can achieve the same purpose, CRC checksum of the introduction is beneficial to maintaining data integrity. However, with bandwidth re-doubled (66MB / s), 11.1MHz was eventually break, so Ultra ATA/66 forced to move out of the ground 40 to increase the design, although results can not be compared with LVD, but finally able to extend the life of to Ultra ATA/133 (running frequency 33.3MHz).

In contrast Ultra2 Wide (U2W) SCSI, 80MB / s of bandwidth do not need to double along the transmission, because the LVD cable sufficient to meet the operating frequency of 40MHz, there is no CRC check data quality is not bad. Along with a pair of Ultra160 SCSI transfer and CRC check, so operating frequency remains unchanged, cables do not have to change; Ultra320 SCSI operating frequency increased to 80MHz, with a special cable required in theory, but the structure of cable no substantive changes, therefore good quality LVD cable can still be used (only connections from the may be some impact).

Distance from the connection, the number of devices to multi-task operating capacity, SCSI built on the underlying architecture is the PATA advantage of not catching, LVD is just one example.

Zhou Hongyi: Free Mode subversive

銆怑DITORIAL: are we likely to make a mistake, that is to take existing business model to cover new applications, it is very easy to draw wrong conclusions. 銆?br />
Although the free model has been discussed for a long time, but I found that many people are still misunderstanding.

I think the "free" is the Internet's genes and blood. If a service is we all need, it must be free, such as search, instant messaging and so on; but the value-added services, not everyone should use, you can be charged. Such as playing games, you do not want to spend time grinding on the inside; some people buy a sword directly on the Swordsman, so the sale of props can be a value-added services.

Chris Anderson summed up the free theory and the Long Tail have built a huge user base, the otherwise can not work. China and the U.S. in the Internet world in the same starting line, also has the largest population, traditionally have 300 million Internet users, mobile users will reach 6 700 million. Therefore, China can find good examples of free patterns, such as Tencent and 360.

Get a free service after a huge user base, then the cost of access to users is almost zero. If the introduction of new products such as Tencent, only their own users to be a description, overnight, a lot of people to use. In addition to value-added service charges, cost savings on the market and huge brand value, is free of charge to the intangible asset model obtained.

I have to do with Charles Zhang said input very good, he say no money, but he found a dog through a free input method can establish the brand and reputation, than to spend the same money play much better advertising results. Such as Mengniu, Yili annual cost a lot of these traditional companies do a lot of advertising in the CCTV, but the real with the 360, Thunderbolt these Internet companies than the last people who come into contact with many? Has a huge user base, follow-up marketing to enter the virtuous circle basically no marketing costs.

But "free" model looks simple, not everyone can do. If you enter an existing market giants, fierce competition, often requires a lot of input. For example, 360 years ago into the security market, it is because we have the support of several million U.S. dollars, or security software is really free to do with their Rising competition is difficult to stick to it. But judging from the United States, Web2.0 era, many creative input is not significant advance, including Twitter, but only if you have a special innovation, to New Two years later we still can not understand how did Twitter matter.

We are easy to make a mistake, that is to take existing business model to cover new applications. For example, Yahoo is doing Banner ads, Google will not operate, but do keyword advertising, this is a commercial model of subversion. Out to Facebook, many people will use search engines point of view of it should do targeted ads, proven advertising model which does not work, Facebook's revenue depends mainly on value-added services, which some like Tencent model.

Look at Twitter, I can tell you, the Company's micro-Bo is not Twitter, it's business model is doomed Sina on the original media model, advertising, or with the operator split, they do not really understand Twitter. I think that, Twitter is a revolution in the future, it may include the Internet, Google is a kind of subversion, this is under way. We can not use the traditional gateway to the business model to see Twitter, or would come to wrong conclusions. Twitter allows communication between people is not a "one on one" or simply "one to many", but a complex network. When the terminal is no longer limited to the Web site Twitter, there may be television, mobile phones, the Internet is subversive, then, now many Internet products will be completely Xiecai, it can ruin an old industry, which is the power of the revolution !
