Agile software development methodology is a lightweight software development method, plays an important role in the software development team. In this paper, we propose programs that in when agile development co-operation, team management, team collaboration and project management tasks can be high efficiency and allocation of human resources. The proposed model, the use of 6-Sigma priority assignment, established a mathematical model of the operation and distribution of human resources is the most reasonable people go to work. Cooperation makes team-based agile development can improve efficiency. This method improve staff efficiency by teamwork to improve the productivity of software development.

Recent trends in construction towards larger scale and taller buildings are causing problems by ineffective existing management approach in construction industry have emerged. Delivering necessary materials and mobilizing the human resources and equipment In a timely manner to keep labor on schedule have become a critical issue to be addressed. In particular, many specialty contractors carrying out multiple projects have been experiencing difficulties mobilizing the manpower on time and in right places due to poor communication at each stage of labor supply, resulting in waste of valuable resources. Hence, it's imperative for the specialty contractors to obtain specific information on labor demand so as to set up a communication and labor management system to ensure the right human resources will be mobilized in the right place at the right time. The study therefore is aimed at developing an optimal human resources management system for specialty contractors performing multiple projects. To that end, the study is focused on rebar and concrete work. The outcome of the study is expected to help allocate the right human resources to the right place in a timely fashion, thereby achieving an effective workflow at construction sites.

급격한 이동통신 기술의 발전에 힘입어 음영지역 해소 및 고속 데이터 처리를 위해 댁내 기지국에 대한 개발 및 연구가 진행 중이다. 댁내 기지국은 크게 음영지역 해소를 위한 Open 방식의 기지국과 고속 데이터 처리를 위해 특정 가입자만 사용할 수 있는 Close 방식이 있다. 상기 방식들은 망의 특성에 맞게 이를 제공하는 망 사업자에 의해 선택 된다. 댁내 기지국을 관리하기 위해서는 많은 시간과 인력자원이 소요되므로 자동으로 설정 및 최적화시키는 기능이 요구 시 되고 있으며, 이를 3GPP에서 SON (Self Organizing Optimizing Networks) 이라 일컫고 연구진행 중이다. 본 논문은 댁내 기지국 관리를 위해 셀의 기본 인자인 PCI(Physical Layer Identity) 할당 방안과 댁내 기지국간 간섭을 최소화 시키기 위한 Adaptive Coverage 방안을 제시한다. 또한 계층적 셀 구성(Hierarchical Cell Structure)에 따른 이동성 제공 방안을 제시한다.

본 연구는 방위산업기술보호법 제정에 따른 국가혁신체제로의 방위산업기술보호 방안을 살펴본다. 특히, 본 연구는 많은 시간과 노력을 통해 개발한 연구개발의 성과를 어떻게 보호해야 할지 측면에서 분석한다. 국내외 기술보호 법령, 조직 등 분석을 통한 시사점을 도출하고 국가혁신체제 관점에서 3가지 개선방안을 제시한다. 전문인력의 단계적 확충 및 전문지원 기관 설립, 효율적인 실태조사 방안 그리고 국가혁신체제 차원에서의 기술보호인식의 전환을 제시한다. 효율적인 방위산업기술보호체계 구축을 위해서 가장 중요한 것은 방위산업기술을 보유한 대상기관 최고책임자(CEO)의 의지이다. 영세한 기업의 경우는 기술보호를 위한 자원의 할당이 쉽지 않기 때문에 CEO가 기술보호에 대한 투자의 중요함을 인식하는 것이 중요하다. 이를 위해서 정부는 지속적으로 기술보호의 중요성에 대한 홍보를 강화하고, 제도적으로 울타리에 들어올 수 있도록 하고, 중소기업의 경우 기술보호체계 구축 등을 우선적으로 지원해야 한다.

Successful project planning relies on a good estimation of the effort required to complete a project, together with the schedule options that may be available. Despite the extensive research done developing new and better models, existing software effort estimation models are present only the total effort and effort (or manpower： people per unit time) function for the software life-cycle. Also, Putnam presents constant effort rate in each subcycles. However, the size of total efforts are variable according to the software projects under the influence of its size, complexity and operational environment. As a result, the allocated effort in subcycle also differ from project to project. This paper suggests the linear and polynomial effort estimation models in specifying, building and testing phase followed by the project total effort. These models are derived from 128 different projects. This result can be considered as a practical guideline in management of project schedule and effort allocation.

In the recent years, a variety of projects have been conducted in order to enhance competitiveness of leading businesses and their followers in the market. Accordingly, the importance of project portfolio management has risen in the open market industry. Project portfolio management refers to crucial decision-making processes which aim to maximize benefits by selecting projects most suitable for a strategic objective among multiple projects with limited resources. In this study, the trend of project portfolio management studies is introduced. The study also presents a mathematical model of the problem, which aims at maximizing project values, possibility, and similarity between projects in the limited resources. We use the genetic algorithm to obtain the priority orders of projects. In order to verify this study, we compare the results of this study and the existing schedules of the E-open market in South Korea. This study ultimately reduces project risks, improves efficiency of development and continuity of tasks by properly ordering projects and assigning developers to the projects.

Software project planning includes several processes for estimating the effort required to complete software project tasks, allocating human resources to tasks, and creating a project plan. Because software planning is becoming more complicated as the size of software projects grow, it is difficult for project managers to decide on a reasonable project plan. To help them, many automatic software project planning approaches have been proposed. The approaches all focus on minimizing project duration. But if the plan is simply to minimize the duration, without considering software quality, the plan can harm the eventual software quality. In our research to create a reasonable project plan, we consider software quality as well as duration of the project, by defining a software quality score. The project manager can plan the project to maximize software quality for a specific project duration.

This study was performed to analysis the social worker's duty in korea and suggest for typology duties of 1st grade social worker, 2nd or 3th grade social worker's qualification. 911 social workers responded to questioner. This objectives was accomplished by the measuring to frequency of duties, and the qualifying cognition of each grade social worker's duties. As a result, social worker spent more time carried out maintenance of facility, direct services, intake, management of file and official document duties than personal management, planning and financial program, evaluation and termination duties. Type of social worker's duties fined out composed of 4 type. Type I(The 1st grade social worker's duties) was belonged to 53 task elements, type IV(The 2nd or 3rd grade social worker's duties) was subjected to 11 task elements. 21 task elements performed to either 1st grade social worker or 2nd, 3rd grade social worker by type or uniqueness of social work practices. To allocation of duties by each grade social worker, fitting out of qualification system, the task elements for each grade of social worker must be prescribed by the rules. This allocation of duties by each grade social worker would be utilized to support qualified social work services, and to strengthening of their professional.

Sufficient understanding of oversea construction market status is crucial to get profitability in the international construction project. Plenty of researchers have been considering the news article as a fine data source for figuring out the market condition, since the data includes market information such as political, economic, and social issue. Since the text data exists in unstructured format with huge size, various text-mining techniques were studied to reduce the unnecessary manpower, time, and cost to summarize the data. However, there are some limitations to extract the needed information from the news article because of the existence of various topics in the data. This research is aimed to overcome the problems and contribute to summarization of market status by performing topic modeling with Latent Dirichlet Allocation. With assuming that 10 topics existed in the corpus, the topics included projects for user convenience (topic-2), private supports to solve poverty problems in Africa (topic-4), and so on. By grouping the topics in the news articles, the results could improve extracting useful information and summarizing the market status.
