IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. It is a natural increment to IPv4. It can be installed as a normal software upgrade in internet devices and is interoperable with the current IPv4. and Ubiquitous is commerce done in anyway, anywhere, anytime, and in every aspect. Since the ubiquitous service is not yet implemented but under development. IPv6 is a new version of IP which is designed to be an evolutionary step from IPv4. This paper describes the concept and classification of IPv6 and compares it with IPv4. IPv6 is a new version of the Internet protocol, designed as the successor to IPv4. This paper suggests critical success factors of IPv6 for ubiquitous. IPv6는 IPv4에서 IP의 진화 단계가 되도록 설계된 새로운 버전입니다. IPv4는 자연적으로 증가한다. IPv6는 인터넷 기기의 정상적인 소프트웨어 업그레이드와 현재의 IPv4와 상호 설치할 수 있도록 하고 있다. 그리고 유비쿼터스란 언제, 어디서나 동시에 존재하는, 도처에 널려있다는 의미로 사용자가 시간과 장소에 구애받지 않고 자유롭게 네트워크에 접속하는 것을 뜻한다. 본 논문에서는 IPv6개념과 특징을 정의한 후 IPv4 유형과 비교하였다. 또한 IPv6는 IPv4의 문제점을 해결하기 위해 설계된 새로운 인터넷 프로토콜이다. 본 논문은 유비쿼터스를 위하여 IPv6의 결정적인 성공요인을 제시하고자 한다.

The protein contents were measured of bacterial substance extracted under various pH and heat, with following results. The kinds of suspending fluid did not have any "influence for the results. Optimal condition for protein detection was neutral pH and temperature of 100C.

The action of salt was studied to the anti-Klebsiella phage serum under the heating and ultra-'violet irradiation, with the following results. Salt protected the activity of antiserum from heat and ultraviolet ray. At the early stage of phage neutralization by the ultraviolet irradiated-antiserum, a delayed curve less than 2-hit curve On heating antiserum in salt solution, the serum protecting activities of salts were similar, so long as their cations were same. The anions showed no influence. On irradiating ultraviolet ray, the protecting action of salt was almost direct opposition to that !1"'*n heating. The anions showed major activity. 0.009 Mol of NaCl had no significant influence to the activity of antiserum. The mechanism of antibody protection of salt was discussed.
