Open Source Software (OSS) is a new paradigm for software development. The system is based on the notion of giving software (including sources) away for free, and making money on services, customizing and maintenance. For these reasons, many software companies have considered adopting and using OSS in Software R&D. A variety of factors may influence the use of decision making of OSS. The objective of this study was to explore the significant factors affecting the use decision of OSS and the job performance of OSS usage in software R&D. A research model was suggested based on the TOE Framework and Information Systems Success Model. These findings show that technical benefits of OSS have significant effects on OSS use. The technical benefits of OSS, and organization context, in turn, have significant effects on the use of OSS. On the other hand, the technical risks of OSS and the environment context have no effects on OSS use. In addition, OSS use and user satisfaction have significant effects on the individual job performance. This research contributes towards advancing the theoretical understanding of the OSS Benefits and Performance in Software Development.

The traditional mass media function of conveying information and forming public opinion has rapidly changed into an environment in which information and opinions are shared through social media with the development of ICT technology, and such social media further strengthens its influence. In other words, it has been confirmed that the influence of the public opinion through the production and sharing of public opinion on political, social and economic changes is increasing, and this change is already in use on the political campaign. In addition, efforts to grasp and reflect the opinions of the public by utilizing social media are being actively carried out not only in the political area but also in the public area. The purpose of this study is to explore the possibility of using social media based public opinion in educational policy. We collected media data, analyzed the main topic and probability of occurrence of each topic, and topic trends. As a result, we were able to catch the main interest of the public(the 'Domestic Computer Education Time' accounted for 43.99%, and 'Prime Project Selection' topics was 36.81% and 'Artificial Intelligence Program' topics was 7.94%). In addition, we could get a suggestion that flexible policies should be established according to the timing of the curriculum and the subject of the policy even if the category of the policy is same.

Algorithms for application-level multicast often use trees to deliver data from the source to the multiple receivers. With the tree structure, the throughput experienced by the descendant nodes will be determined by the performance of the slowest ancestor node. Furthermore, the failure of an ancestor node results in the suspension of the session of all the descendant nodes. This paper focuses on the transmission of data using multiple virtual forwarders, and suggests a scheme to overcome the drawbacks of the plain tree-based application layer multicast schemes. The proposed scheme elects multiple forwarders other than the parent node of the delivery tree. A receiver receives data from the multiple forwarders as well as the parent node and it can increase the amount of receiving data per time unit. The multiple forwarder helps a receiver to reduce the impact of the failure of an ancestor node. The proposed scheme suggests the forwarder selection algorithm to avoid the receipt of duplicate packets. We implemented the proposed scheme using MACEDON which provides a development environment for application layer multicast. We compared the proposed scheme with Bullet by applying the implementation in PlanetLab which is a global overlay network. The evaluation results show that the proposed scheme enhanced the throughput by 20 % and reduced the control overhead over 90 % compared with Bullet.

Configuration and data management system to support processes for the weapon system should support the concurrent engineering and collaborative activities for various documents, drawings, part informations and structural informations, etc. which are produced through R&D processes for a long time. This thesis attempts to identify major functions in the configuration and data management system to support processes for the weapon system R&D into services based on a service oriented architecture. In order to identify major services in the configuration and data management system to support processes for the weapon system R&D, a configuration and data management system to support processes for the weapon system R&D was proposed with a service oriented architecture with four layers including a service consumer layer, a business service layer, an application service layer and a application layer, and major services were identified for each layer. In order to identify major services in four layers, this thesis adopted a bottom-up approach to identify the necessary business services from a well-defined domain implementation system rather than a top-down identification method in general. This thesis tried to identify the essential services in implementing the configuration and data management system to support processes for the weapon system R&D as a system based on the service oriented architecture using such a bottom-up service identification method while limiting those services to the general PDM system aspects and the business areas of the configuration and data management system to support processes for the weapon system R&D.

It is settled in the economic arena that electronic commerce which used the Internet is new recently by explosive increase of the rapid development and Internet use of the information and communication technology. The problem that is legitimate at a point called the business of the form that the electronic transactions to set together if I drift are new of the times is the situation caused a lot. However, the use custom of construction and electronic transactions of the maintenance that is the legislation thief who can do rules of electronic transactions is the fact that it was not able to be still established It may not be just applied to the Internet electronic transactions that an exchange promise between our characters does against unspecified number of the general public person in the property even if I say that the conclusion of the purchase agreement is concluded in Internet electronic transactions by EDI method. That can have the approval of contract in the main legal problem of such an Internet electronic transactions contract. We civil law sorts it by a contract between the talks characters and a contract between the remote area people and all the adopted children are equal and must decide the formation of contract time in a principle of Empfangstheorie because it may be said that the rule of the civil law that it be heated and decides to be able to be available is irrational.

자연언어 처리에 있어 문장의 성분 구조를 파악하는 통사적 해석에서는 애매성 있는 결과가 많이 생성된다. 한국어의 경우 어순 등의 통사적 특성뿐 아니라 상황과 의미, 문맥이 문장의 분석에 더 중요한 역할을 하기 때문에 문맥 자유 문법에 의한 접근 방법만으로는 중의적 구조의 해결이 어렵다. 이는 또한 의미 분석시 애매성을 증가시키는 원인이 된다. 이러한 통사적, 의미적 중의성 해결을 위해 용언 중심의 하위범주화 사전을 구축하였다. 본 논문에서는 용언에 따라 제한될 수 있는 하위범주 패턴을 정의하고 패턴에 따라 하위범주 사전을 구축하였다. 하위범주화 사전에는 명사의 시소러스와 정합하여 보어를 선택 제한(Selectional Restriction)할 수 있도록 용언과 명사와의 의미적 연어 관계에 따라 의미마커를 부여했다. 말뭉치를 통해 수집된 용언 12,000여개를 대상으로 25,000여개의 하위범주 패턴을 구축하였고 이렇게 구축한 하위범주화 사전이 120,000여 명사에 대한 의미를 갖고 있는 계층 시소러스 의미 사전과 연동하도록 하였다. 또한 논문에서 구현된 하위범주화 사전이 구문과 어휘의 중의성을 어느 정도 해소하는지 확인하기 위해 반자동적으로 의미 태깅(Sense Tagging)된 2만여 문장의 말뭉치를 통해 검증 작업을 수행하고, 의존관계와 어휘의 의미를 포함하고 있는 말뭉치에 하위범주 패턴이 어느정도 정합되는지를 분석하여, 하위범주 패턴과 말뭉치의 의존관계만 일치하는 경우와 어휘의 의미까지 일치하는 경우에 대해 평가한다. 이 과정에서 하위범주 패턴에 대한 빈도 정보나, 연어 정보를 수집하여 데이터베이스에 포함시키고, 각 의미역과 용언의 통계적 공기 정보 등을 추출하는 방법도 제시하고자 한다.을 입증하였다.적응에 문제점을 가지기도 하였다. 본 연구에서는 그 동안 계속되어 온 한글과 한잔의 사용에 관한 논쟁을 언어심리학적인 연구 방법을 통해 조사하였다. 즉, 글을 읽는 속도, 글의 의미를 얼마나 정확하게 이해했는지, 어느 것이 더 기억에 오래 남는지를 측정하여 어느 쪽의 입장이 옮은 지를 판단하는 것이다. 실험 결과는 문장을 읽는 시간에서는 한글 전용문인 경우에 월등히 빨랐다. 그러나. 내용에 대한 기억 검사에서는 국한 혼용 조건에서 더 우수하였다. 반면에, 이해력 검사에서는 천장 효과(Ceiling effect)로 두 조건간에 차이가 없었다. 따라서, 본 실험 결과에 따르면, 글의 읽기 속도가 중요한 문서에서는 한글 전용이 좋은 반면에 글의 내용 기억이 강조되는 경우에는 한자를 혼용하는 것이 더 효율적이다.이 높은 활성을 보였다. 7. 이상을 종합하여 볼 때 고구마 끝순에는 페놀화합물이 다량 함유되어 있어 높은 항산화 활성을 가지며, 아질산염소거능 및 ACE저해활성과 같은 생리적 효과도 높아 기능성 채소로 이용하기에 충분한 가치가 있다고 판단된다.등의 관련 질환의 예방, 치료용 의약품 개발과 기능성 식품에 효과적으로 이용될 수 있음을 시사한다.tall fescue 23%, Kentucky bluegrass 6%, perennial ryegrass 8%) 및 white clover 23%를 유지하였다. 이상의 결과를 종합할 때, 초종과 파종비율에 따른 혼파초지의 건물수량과 사료가치의 차이를 확인할 수 있었으며, 레드 클로버 + 혼파 초지가 건물수량과 사료가치를 높이는데 효과적이었다.\ell}$ 이었으며 , yeast extract 첨가(添加)하여 배양시(培養時)는 yeast extract

The purpose of this study is to examine the job characteristics of care workers in elderly care voucher service emphasizing a social service quality management approach. The study sample was composed of randomly-selected 233 centers which dispatched care staffs to clients' home. Descriptive analyses were performed for examining the unique aspects of relationship-based labor of care staffs, and logistic regression analyses were performed for investigating the association between service quality structure and human right violation against staffs. As the first empirical study focusing on staff-side service quality factors, this study found out that human right violation against staffs was mainly influenced by record-keeping and document management capacity of center, risk protection under insurance, compliance of standard contract procedure, and regular supervision. These results suggest particular policy attention should be given to basic protection for and set-up of core activity boundaries of care workers as well as clients-centered rights both for preventing human right violation and improving overall social service quality.

The objective of this research is to depict examples of how a company could derive the skillset areas with the highest priority when analyzing the skill set requirements of human resources, based on the skillset requirements that are unique to each work site. For this purpose, a survey was conducted for each of the job categories for new employee in A company. The analysis results showed that in 32 out of the 34 areas, the gaps between the current levels and the expected levels were statistically significant. For employees of company A, the following 7 areas were determined to be the key job competencies with the highest priority: document creation skills, diagram creation skills, thinking skills, problem solving skills, time management skills, technology comprehension ability, and task comprehension skills. The required job competencies with the highest priority were found to be different for each job category. As a result of this research, the priority rankings of skillset requirements for each job category in company A could be determined, along with the implications for HRD/HRM and other companies.

A point of interest is a specific point location such as a cafe, a gallery, a shop, or a park. It consists of a name, a category, a location, and so on. Its information is necessary for location-based application, above all category is basic information. However, category information should be automatically gathered because it costs high to gather it manually. In this paper, we propose a novel method to estimate category of POIs automatically using an inner word and local context. An inner word is a word that contains POI's name. Their name sometimes expose category information. Thus, their name is used as inner word information in estimating category of POIs. Local context information means words around a POI's name in a document that mentioned the name. The context include information to estimate category. The evaluation of the proposed method is performed on two data sets. According to the experimental results, proposed model using combination inner word and local context show higher accuracy than that of model using each.

Finding aids have existed from the time when ancient archives appeared, With this long history, they have been used in most of Western archives, and thus, it is one of the most familiar tasks generally performed by archivists. However, ironically, this accustomed concept has not been an academic object to many researchers. Especially, in this electronic age, finding aids are even more complicated in their forms and meanings. This paper intends to address the concept(s) of finding aids as reflected in the archival literature in North America. The paper will attempt to illustrate how the concept of finding aid has evolved both conceptually and practically in archives and archival science and how circumstantial and social elements affect this concept. It Seems that the concept of finding aids has developed from the broad and integrated concept of provenance and pertinence to the narrower and practical sense considering the use by the public. It also turns out that the concept has advanced from a mere technical tool for describing records to an access tool for maximum availability. Not surprisingly, the concept of finding aids have changed as archival science and the profession has advanced and diversified. It is crucial for the archival community to understand changes in the practice and the concept of finding aids that will enable the preparation of higher quality finding aids enabling the optimum use of archives.
