There is a difficulty for many practioner in anterior direct restroation with composit resin. Because its result is various according to patient, a practioner have a fear about that unpromisable result. Moreover in esthetic region, there is difference in satisfaction by patient character. That is one of difficulty in this practice. But if we make a manual for parctice it will be easier. So I will summarize the process and things to note in direct anterior composite resin restoration.

In this paper, we propose an efficient authentication protocol based on certificateless signature scheme, which does not need any infrastructure to deal with certification of public keys, among the vehicles in Vehicular Ad-hoc Networks. Moreover, the proposed protocol introduces the concept of interval signature key for efficiently solving the problem of certificate revocation.

보안 어댑터를 이용하여 하드웨어적으로 해킹 등 사용자가 의도하지 않은 방법으로 정보(자료)가 타인에게 유출되는 것을 방지하기 위한 보안 시스템에 관한 것이다. 보안 어댑터 KEYS/sup TM/ 는 컴퓨터 시스템과 키보드 사이에 설치하여 사용하는 것으로 키보드 입력 정보에 대한 해킹을 원천적으로 차단하기 위한 기술이다. 해커의 위험으로부터 정보를 보호하는 것 뿐만 아니라 내부자의 불법적 정보유출이나 사용자 실수에 의한 정보 손실을 차단하는 등, 자산적 가치를 지닌 정보를 보존하기 위해 다양한 기능을 제공하는 통합적 정보보호 시스템을 소개한다.

본 논문에서는 무선환경을 고려하여 타원곡선 암호시스템을 기반으로 하는 AKC 프로토콜(Authenticated Key Agreement with Key Confirmation Protocol)을 제안한다. 제안 프로토콜은 2명의 객체가 한번의 세션과정을 통해서 복수개의 공유키를 생성하며 주기적으로 키를 refresh함으로써, 현재 안전한 암호 알고리즘의 수출규제에 따른 대안으로 사용되어질 수 있다. 또한 이미 알려진 여러 공격에 대한 안전성을 상세히 고찰한다.

This study examined the taxonomic composition of marine benthic algal flora from Maxwell Bay, King George Island, Antarctica, collected between January 1988 and January 1995. The rhodophyte specimens collected and examined included a total of 20 genera and 20 species of red algae. Of these, 2 species, Kallymenia antarctica Hariot and Pantoneura plocamioides Kylin, were recorded in Maxwell Bay for the first time. Taxonomic keys for the rhodophytes are also provided.

Recent herbarium reexamination and field studies yielded two monocotyledonous plant taxa of the family Poaceae that could be documented in the national inventory list of species of Korea. These species, collected from Jeollabuk-do and Gyeongsangnam-do, were introduced and naturalized in Korea. Two species were identified as Holcus mollis L. and Aira elegantissima Schur. We provided the descriptions and descriptive photos of these species. Keys to the newly recorded species and related taxa were also provided.

This paper aims at implementing a new program designed to improve the level of communicative competence of Korean learners of English. For this purpose, the most important issue to be resolved is defined first. Then, a brief survey of the literature on the nature of communicative competence. Next, methodological considerations are added in because they are thought to be the keys to success. Lastly, the main teaching points are presented to ensure the success. The paper as a whole is a presentation of a new program for a better communicative competence. The new program is nothing other than actual communicative practice which ensures an authentic interaction.

In this paper, we propose an efficient encryption algorithm, without exchanging session keys of a symmetric cryptosystem. The proposed scheme, called as the FAKE(Fast Asymmetric Key Encryption), first scrambles an entire input message and then encrypts small parts of the scrambled message using an asymmetric key encryption scheme. We use the all-or-nothing transform based on the hash function as a scrambling function, which was proposed by Shin, et al. Furthermore, the proposed scheme can additionally provide a digital signature service with only small overhead.

Megaselia scalaris (Diptera: Phoridae) is one of the medically important insects. Maggots from a urine sample of a 5-year-old Saudi girl were examined microscopically for identification. These maggots were cultured to become adult flies. Larvae and adults were identified using standard keys. Protozoan flagellates were obtained from the gut of the larvae. This is the first report of M. scalaris as a causative agent of urinary human myiasis in Saudi Arabia.
