It is a very important to manage inventory quickly and accurately in Refrigerated commercial warehouses in which a lot of logistics are often shipping and receiving. Because most of systems for managing refrigerated warehouses consist of COBOL, it will be raised maintenance costs. There is no service for consignees who are consumer of refrigerated warehouses and they use only a fax or a phone for orders. In this paper, we design a web mobile middleware platform supporting legacy systems and based on SaaS which supports a variety of value-added services which are fit consignees, solving problem of outdated legacy systems and no services for consignees.

정보시스템의 복잡성과 컴퓨팅 환경의 변화에 따라 시스템 성능 및 용량 산정의 중요성이 점점 부각되고 있다. 특히, 클라우드 컴퓨팅은 막대한 서버자원이 필요하기 때문에 보다 체계적이고 정확하게 HW 용량을 산정하는 것은 중요한 요소이다. 클라우드 컴퓨팅은 이제 도입기를 지나 성숙기를 향해 빠르게 진보하고 있는 상황이다. 지금까지 클라우드는 IaaS, PaaS, SaaS 등으로 발전해왔다. 특히, 국내 다수의 IT 서비스 기업들은 클라우드 인프라가 구축된 기업들과 MOU를 맺고 SaaS를 제공하고 있다. 따라서, 클라우드 서비스의 기본이 되는 SaaS를 위한 하드웨어 용량 산정 기법에 관한 연구는 향후 클라우드 내에서 다양한 사업으로 확장하는데 필요한 기반 연구이다. 이에, 본 연구에서는 SaaS 기반의 하드웨어 용량산정에 대한 방법과 기준을 제시하였다. 본 연구의 결과는 클라우드 컴퓨팅 환경구축 시 HW용량산정에 대한 가이드라인으로 활용 가능하다.

SaaS를 기존의 ASP 방식과 비교해 보면, 사용자의 입장에서는 소프트웨어를 인터넷을 통해 사용하는 점에서는 큰 차이는 없으나 사용자를 위한 커스터마이징을 ASP처럼 소프트웨어 공급자가 하지 않고 사용자가 직접 할 수 있다는 점에서 차별성을 갖는다. 본 논문에서 제안한 SaaS 플랫폼 기반 통합도서관시스템은 사용자의 커스터마이징을 메타데이터를 활용해서 지원하며 사용자들 또는 사용자 그룹으로 표현되는 테넌트들을 하나의 소프트웨어 인스턴스로 지원(single instance multitenant) 한다는 점에서 차별성을 갖는다. 이는 커스터마이징에 많은 비용이 들고 인스턴스를 개별적으로 띄우기 때문에 규모의 경제를 실현하지 못했던 ASP의 단점을 해결했다.

The concept of IPv6 stateless address autoconfiguration lends itself easily to mobile ad hoc networks. However, the Neighbor Discovery protocol (NDP)-based mechanism described in [1] does not fit well for the multi-link environments in the mobile ad hoc network. In this document, we extend the current SAA mechanism to be suitable for mobile ad hoc networks.

Web 2.0 시대가 도래하면서부터 새로운 소프트웨어 배포 방식인 SaaS가 등장하였다. 보안 분야에서도 기존의 소프트웨어적인 보안 방식이 아닌 하드웨어적인 보안 방식을 위해 TPM이라는 보안 칩이 개발되었다. 본 논문에서는 TPM 칩을 사용하여 보다 신뢰적인 측면이 강조된 신뢰 컴퓨팅 기반 SaaS 모델을 설계하고, 설계된 모델의 가장 기본적인 기능인 로컬 PC 레벨의 PCR 값 인증 프로그램과 로컬 PC 레벨 어플리케이션 무결성 측정 프로그램을 구현하고 이를 평가한다.

Physical and chemical barriers, caused by the close association of the main components of cellulosic biomass, hinder the hydrolysis of cellulose to fermentable sugars. Since the main goal of pretreatment is to increase the enzyme accessibility improving digestibility of cellulose, development of an effective pretreatment process has been considered to be important. In this study, SAA (Soaking in Aqueous Ammonia) was chosen as pretreatment because this is the simple and low-cost method. Rice straw of which the production is outstandingly high in domestic agriculture residues in Korea was chosen as raw material. SSA pretreatment with various reaction time of 3 h to 72 h was tested. The enzymatic hydrolysis and SSF (Simultaneous Saccharification and Fermentation) were performed at three different temperature (30, 40 and $50^{\circ}C$) to investigate performance of SSF upon various pretreatment conditions. As a result, this SAA treated-rice straw was found to have great potential for effective enzymatic hydrolysis and SSF with lower enzyme dosage at lower temperature ($30^{\circ}C$) than its conventional SSF. In SAA addition, SAA reduced fermentation time to 24 h owing to increase the initial hydrolysis rate substantially.

Severe aplastic anemia (SAA) is a life-threatening disorder for which allogeneic hematopoietic stem cell transplantation (HSCT) is the current available curative treatment. HSCT from matched sibling donors (MSDs) is the preferred therapy for children with acquired SAA. For patients who lack MSDs, immunosuppressive therapy (IST) is widely accepted as a first-line treatment before considering HCT from an unrelated donor (URD). Given the recent progress in HSCT using URDs for childhood SAA, well-matched URDs became a realistic alternative for pediatric patients who have no suitable related donors and who are refractory to IST. However, it is quite challenging to treat patients with refractory SAA who lack suitable related or URDs. Even though haploidentical HSCT from genetically mismatched family members seemed to be an attractive procedure with the amazing benefit of readily available donors for most patients, early attempts were disappointing because of refractory graft-versus-host disease (GVHD) and excessively high transplant-related mortality. Recent advances with effective ex vivo depletion of T cells or unmanipulated in vivo regulation of T cells, better supportive care, and optimal conditioning regimens have significantly improved the outcome of haploidentical transplant. Besides considerable progress in the treatment of malignant diseases, recent emerging evidences for haploidentical HSCT in SAA has provided additional therapeutic options for patients with refractory diseases. Further improvements to decrease the rates of graft failure, GVHD, and infectious complications will facilitate the emergence of haploidentical HSCT as a front-line therapy for treating acquired SAA in children and adolescents who have no suitably matched donors.

Agriculture has played a significant role in the national economy, contributing to food security, driving economic growth, and safeguarding the dietary habits of the population. Korean agriculture has been compelled to focus on intensive farming due to its limited cultivation area, excessive input costs, and the limitations of agricultural mechanization. In the Republic of Korea (R.O.K), the concept of environmentally friendly animal agriculture began to be introduced in the early 2000s. This concept ultimately aims to cultivate sustainable animal agriculture (SAA) through environmentally friendly production practices, ensuring the healthy rearing of animals to supply safe animal products. Despite the government's efforts, there are still significant challenges in implementing environmentally friendly agriculture and SAA in the R.O.K. Therefore, the objective of this review is to establish the direction that the animal agriculture sector should take in the era of climate crisis, and to develop effective strategies for SAA tailored to the current situation in the R.O.K by examining the trends in SAA in the U.S. The animal agriculture sector in the U.S. has been working towards creating a SAA system where humans, animals, and the environment can coexist through government initiatives, industry research, technological support, and individual efforts. Efforts have been made to reduce emissions like carbon, and improve factors affecting the environment such as the carbon footprint, odor, and greenhouse gases associated with animal agriculture processes for animals such as cattle and pigs. The transition of the U.S. towards SAA appears to be driven by both external goals related to addressing climate change and the primary objectives of responding to the demand for safe animal products, expanding consumption, and securing competitiveness in overseas export markets. The demand for animal welfare, organic animal products, and processed goods has been increasing in the U.S. consumer market. A major factor in the transformation of the U.S. animal agriculture sector in terms of livestock specifications is attributed to environmentally friendly practices such as high-quality feed, heat stress reduction, improvements in reproductive ability and growth period reduction, and efforts in animal genetic enhancement.
