Antimicrobial Peptides are natural antibiotics evolved by many plants, invertebrate, and vertebrate to defend against the microbial infection. Antimicrobial peptides show a broad-spectrum antimicrobial activity with little opportunity for the development of resistance since they target microbial membranes that distinguish microbes from enkaryotic cells. The oral cavity is constantly exposed to microbial challenges and antimicrobial peptides play an important role in managing the oral health. With the increase of resistant micro-organisms to conventional antibiotics, antimicrobial peptides are attracting interests as novel antibiotics. In this review, the characteristics of antimicrobial of antimicrobial peptides including the classification, mechanism of action, resistance, and expression in the oral cavity have been discussed in the prospects of application to oral disease.

Today power system technology is being converged with communication system technology or information technology (IT). This conversion action affects on two parts vigorously so that IT has become very essential in power industry. But terminologies of two parts are confused and it is necessary that these are standardized to develop the industry mush more because the standardization is the first step of preparation to FTA environments.

최근 활발히 개발 중인 보안운영체제의 핵심인 보안커널(security kernel)은 참조모니터(reference monitor)에서 주체(subject)가 객체(object)에 대한 실행(action) 권한을 판단함으로써 접근 제어를 실행한다. 보안운영체제의 대표적인 접근제어모델에는 다중레벨접근제어(MLS: Multi Level Security)모델과 역할기반접근제어(RBAC: Role Based Access Control) 모델 등이 있다. 리눅스 시스템에서 이러한 접근제어모델을 적용하기 위해서 접근 대상이 되는 객체들의 효과적인 분류가 요구된다. 본 논문에서는 리눅스 환경에서 효과적인 접근제어모델을 적용하기 위하여 객체들을 객체 클래스(class)와 유형(type)을 기준으로 분류 하였다.

This paper has examined the current status of Korea's welfare policy and asserts the necessity of artist classification by types of employment, dividing them into those who have irregular jobs and those who are in permanent positions, focusing on filmmakers. Furthermore, it has looked into the certification policy for artist welfare support that is currently in action. In conclusion, this paper discusses the certification and suggests implementation methods for "Artist Welfare Card" in expectation of future activation of Artist Welfare Support Project.

Bacteriocins in Gram-positive bacteria have attracted much attention because many have a strong antimicrobial activity also against bacteria outside the genera of the producers. Lantibiotics and the pediocin-like bactericins have attracted most attention since they kill a broad spectrum of Gram-positive bacteria including important pathogens. But many other promising Gram-positive bacteriocins have been thoroughly characterized. Recent studies have shown that bacteriocins may playa role in the intestinal flora to protect us against the food-borne pathogens. Bacterial genome sequencing has demonstrated that there may be an arsenal of such compounds and we are only seeing the top of the iceberg. The present review gives a short outlook of the field of bacteriocins with focus on lactic acid bacteria and includes recent findings.

AGV is very useful equipment to transfer containers in automated container terminal. AGV must have Obstacle Detection System (ODS) for port automation. ODS needs the function to classify some specified object from background in acquired data. And it must be able to track classified moving objects. Finally, ODS could determine its next action for safe driving whether it should do emergency stop or speed down, or it should change its deriving lane. For these functions, ODS can have many different kinds of algorithm. In this paper, we present one of AGV to be used in automated container terminal.

This study aims to summarize and makes a reference of anti-inflammatory activities of herbal medicines. In this process, this review collated papers of anti-inflammation-focused studies using herbal medicines in Oriental medical journals since 2003. Finally 221 papers were included and the type of materials, the type and effective classification of herbal medicines, the type of cells used in the experiments and the action and mechanisms of herbal medicine were analysed. The herbal medicines having the effects of decreasing fire and tonifying and nourishment were used the most. Most herbal medicines in this study can decrease proinflammatory cytokines, NO and prostaglandin 2 (PGE 2) production, inducible nitric oxide synthase (iNOS) and cyclooxygenase-2 (COX-2) expression by regulating of nuclear factor kappa B (NF-${\kappa}B$) and/or mitogen activated protein kinases (MAPKs).

The clinical and statistical evaluation on the patients of maxillofacial deformities who were operated by author were analyzed after several month or years or se. Pre and post operative cephalometric radiographs of 45 orthognathic surgery patients were compared. The post operative radiographs had been taken at least 9 month to several years. Measurements were made between constructed hard tissue and soft tissue points located on each before and after film tracing. The items studied and evaluated are as follows: 1) Classification and divid of patients 2) Operation technic adopted by operator. 3) Motives of patients for operation and their untowards. 4) Self satisfication of patients after operation. 5) Post operative changes of soft and hard tissue. 6) Side action during and after operation.

Bronchial asthma is a major public health problem worldwide and the morbidity and mortality of asthma have increased in last few decades. There is high prevalence of usage of alternative traditional system of medicines for the treatment of asthma. Large numbers of medicinal plant preparations have been reported to possess anti-asthmatic effects. Plant cells are now considered to be the chemical factories synthesizing a large variety of chemical compounds. Further, Ayurvedic system of medicine has an elaborate description of asthma from the earliest times describing it as 'Shwasa' meaning disease pertaining to breathing. This review classifies the antiasthmatics herbs based on the possible mechanism of action reported. Thus, these plants can be used to obtain a polyherbal formulation which contains various herbs acting at particular sites of the pathophysiological cascade of asthma for prophylaxis as well as for the treatment of asthma.

We provide a fudamental set of information on technologies in the area of mechanical engineering to draw action plans for intermationalization of the National R&D activites. First, we design and use a modified Delphi method to evaluate levels of our technological capabilities and developed countries' as well. We investigate technology acquistion methodolgies, technology characteristcs and various aspects of international cooperation in terms of technology. Secondly, we analyze final responses of participants (i.e,. the third round results of Delphi method) tosee the correlation between various factors in developing mechanical engineering technologies through international cooperation. The technology classification used in this research is developed by STEPI (Science and Technology Policy Institute).
