  • 객체지향기술(OOT)이 주목을 받으면서 다양한 이론들이 발표되었고, 산업계에서 적용이 시도되어 왔으나 그 인기에 비해 OOT의 저변을 확대시키지는 못하고 있다. OOT의 도입, 확산에 걸림돌이 되고 있는 오해들을 살펴봄으로써, 객체기술을 도입하고자 하는 기업들의 올바른 이해를 돕고자 한다.

  • As the scale of airborne system software increases, the use of OOT (Object-Oriented Technology) is increasing for functional expansion, efficient development, and code reuse, but the verification method for airborne object-oriented software is conducted from the perspective of the existing procedure-oriented program. The purpose of this paper was to analyze the characteristics of OOT and the vulnerabilities derived from the functional characteristics of OOT, and present a verification method applicable to each software development process (Design, Coding and Testing) to ensure the functional safety integrity of aviation software to which OOT is applied. Additionally, we analyzed the meaning of the static analysis results among the step-by-step verification measures proposed by applying LDRA, a static analysis automation tool, to PX4, an open source used to implement flight control software.

  • This paper is a part of “The Study of the Traditional Korean Ethenic Farmhousing in Yanbian, China”. The purpose of this study is to identify reception behavior and places for guests of the traditional farmhouse. In this study, a survey using questionnaire was conducted in which one hundred and twenty four farmhouses were analyzed thoroughly. The major findings are as follows : 1) Most frequent guest receptions among Dallejae residents are casual meetings of relatives and non-relatives, husbands' birthday parties, one-year birthday Parties of children, wedding receptions, and Whankap (sixtieth birthday party). 2) They receive guests and serve them at Chung-ji-kan and Oot-bang. 3) Reception behavior has undergone change along with social, political, and economical changes. They receive guests with much more hospitalities than before. Only memorial services are simplified compared to the past.

  • In this paper, we study the usage of phoneme duration information for rejection garbage sentence. First, we build a phoneme duration modeling in a speech recognition system based on dicicion tree state tying, We assume that phone duration has a Gamma distribution. Next, we build a verification module in which word-level confidence measure is used. Finally, we make a comparative study on phoneme duration with speech DB obtained from the live system. This DB consistes of OOT(out-of-task) and ING(in-grammar) utterences. the usage of phone duration information yields that OOT recognition rate is improved by 46% and that another 8.4% error rate is reduced when combined with utterence verification module.

  • 망 운용에 있어서 망 관리 시스템은 다양한 네트워크 장비의 증가로 인하여 점점 더 중요한 위치를 차지하고 있다. 과거 망을 구성하는 요소는 네트워크 장비로 국한되었지만 현재는 서비스를 지원하는 데몬(Daemon) 등 장비 외적인 요소까지 속하게 되어 더욱 복잡해 지고 있다. 기존의 망 관리 시스템은 SNMP(Simple Network Management Protocol)나ICMP(Internet Control Message Protocol) 프로토콜을 사용하였으나 이 기술만으로는 데몬과 같은 장비 외적인 요소들까지 제어, 관리하지 못했다. 반면. TELNET등과 같은 기능을 추가적으로 이용할 수 있다면. 보다 쉽게 망 정보를 얻을 수 있는 장점이 있어 기존의 망 관리 시스템에서 지원하지 못했던 기능의 한계점을 극복할 수 있다. 이에 본 논문은 객체지향기술(OOT : Object­Oriented Technology)을 도입하였다. 클래스(Class)는 고유한 특성을 가지는 관리 대상 종류를 선언한 것이고. 관리 대상은 네트워크 장비 뿐만 아니라 데몬이나 지역, 부서등과 같은 추상적인 대상이 포함되며 이는 객체(Object)를 의미한다. 또한. 상속(Inheritance) 개념을 도입하여 중복요소를 없앴으며, 클래스의 메소드(Method)에 관리 대상을 처리할 수 있는 기능을 정의하였다. 기능 정의에는 SNMP와 TELNET. ICMP등을 내부적으로 이용하여 구현된 스크립트(Script)를 이용하였다.

  • The antimicrobial substance produced by Lactobacillus bulgaricus was inactivated by protease. It showed inhibitory activity against Staphylococcus aureus ATCC6538, Streptococcus agalactiae ATCC14364, some Gram-positive and Gram-negative bacteria, and characteristics of a bacteriocin. The optimal temperature and culture time for the production of bacteriocin were $30^{\circ}C$ and 10 h, respectively, in the culture of L. bulgaricus. The bacteriocin production started in the exponential phase and reached a maximum at the early stationary phase. Using Staph. aureus ATCC6538 and Strep. agalactiae ATCC14364, known as common bovine mastitis pathogens, as indicator strains for determination of the bacteriocin activity, the antimicrobial activity of the bacteriocin was found to be stable in acidic and neutral pH's (2- 7) even at lOOT, whereas it was lost at high pH (10- 11) and $100^{\circ}C$. The mode of action for the antimicrobial activity was bacteriocidal, and the molecular weight determined by SDS-PAGE and overlay method was 14 kDa.

  • 21세기를 맞이하는 기업은 세계화와 국제화, 정보의 다양화 및 분산화, 제품수명주기의 단축과 수익률의 감소, 고품질의 제품, 지식산업의 등장, 고객 욕구의 증대 등 다양한 내 ${\cdot}$ 외적 환경변화에 대응해야 하고 경쟁우위를 확보하기 위해 끊임없이 기업의 변화능력을 확보해야 한다. 기업은 제품을 생산하여 판매하는 기업의 시스템 전체가 경쟁력을 갖추어 총체적 우위를 확보하고 고객의 기호와 감성에 호소하는 제품을 만들 수 있도록 다양한 정보를 제공하는 시스템을 필요로 하게 되었다. 즉, 시간과 서비스에 뒤진 고객지원체계는 기업의 성장에 절대적인 마이너스 요인이므로 고객 정보의 효율적 관리, 고객 요구에 대한 신속한 대응, 정기적 고객만족도 조사 등 고객이 원하는 것을 재빠르게 얻어낼 수 있는 고객 친밀형 정보시스템의 확립이 요구되는 것이다. 이를 해결해 줄 수 있는 새로운 경영정보시스템이 바로 WebERP인 것이다. WebERP는 기업의 원활한 자재, 구매활동을 위해 제안된 MRP에서 시작되었으며, 생산관리의 개념을 포함하고 있는 MRPII로 확대되었다가 다시 인사나 회계, 재무 등 조직이나 기업의 전업무영역을 수용하는 종합경영정보시스템으로 발전된 것이다. 현재는 전자상거래와 관련하여 WebERP의 필요성이 부각되었고, 모기업과 협력사간의 구매발주 및 납품관리를 확대시켜 소모성자재(MRO: Maintenance, Repair & Operation) 및 기타 공동구매서비스와 유사업종간의 그룹을 형성하여 ASP(Application Service Provider)의 공동 환경을 이용한 WebERP 환경을 이용한 WebERP활용이 현시점으로 적실히 필요한 것이다. 이는 중소기업들의 공동 협업체제를 도모하여 외세를 대비하는 응집력을 확고히 함으로써 집단체제의 e마켓플레이스 확립과 더불어 국제경쟁을 대비한 방안으로서 집단 공동의 웹환경 인프라가 필요한 것이다. 이러한 배경에서 ASP환경을 이용한 WebERP활용방안과 시스템 구축전략을 경남지역의 기계산업정보화사업단이 추진하는 일반기계, 전기기계, 금속기계, 수송기계, 정밀기계의 5개 업종을 4,877개 기업 대상으로 추진하고 있으며, 그 중 WebERP의 모델로서 2003년도까지 50개 기업을 선정하고, 이는 5개 업종 골고루 선정하여 적용과 표준화 모델로 전개해 나가는 것을 정리한 것이다.
