In this study, the productivity factors of software maintenance are categorized into the three areas such as maintainer characteristics, software technical characteristics and maintenance environment characteristics. And the various regression analyses are performed for searching the most significant model by using actual project's data. At conclusion, an linear model including new variables derived from factor analysis to estimate the effort for software maintenance project is suggested.

Manpower demand forecasting in private security industry can be used for both policy and information function. At a time when police agencies have fewer resources to accomplish their goals, forming partnership with private security firms should be a viable means to choose. But without precise understanding of each other, their partnership could be superficial. At the same time, an important debate is coming out whether security industry will continue to expand in numbers of employees, or level-off in the near future. Such debates are especially important for young people considering careers in private security industry. Recently, ARIMA model has been widely used as a reliable instrument in the many field of industry for demand forecasting. An ARIMA model predicts a value in a response time series as a linear combination of its own past values, past errors, and current and past values of other time series. This study conducts a short-term forecast of manpower demand in private security industry using ARIMA model. After obtaining yearly data of private security officers from 1976 to 2008, this paper are forecasting future trends and proposing some policy orientations. The result shows that ARIMA(0, 2, 1) model is the most appropriate one and forecasts a minimum of 137,387 to maximum 190,124 private security officers will be needed in 2013. The conclusions discuss some implications and predictable changes in policing and coping strategies public police and private security can take.

급변하는 e비즈니스 환경과 IT기술 발전으로 인해 e비즈니스 인력의 수급예측은 매우 어려운 실정이다. 이는 e비즈니스 인력수급 불균형, e비즈니스 산업분야별 인력양성 정보제공의 어려움 등의 원인으로 작용하고 있다. 이에 본 연구에서는 e비즈니스 인력수급 실태조사를 통해 e비즈니스 산업에서 실제로 활용 가능한 인력양성 방안을 제시하고자 한다. 이를 위해 기업체, 교육기관, 취업자 등 조사대상을 3개로 하여 조사를 실시하였으며, 결과를 바탕으로 e비즈니스 산업 분야별 인력수급 실태와 기존 e비즈니스 인력양성 프로그램의 문제점을 분석하였다. 본 연구의 결과를 통하여 정부의 e비즈니스 인력 관련 정책수립에 도움을 줄 수 있으며, 기업체, 교육기관에게는 인력양성을 위한 지침으로서의 활용이 기대된다.

It is not easy to predict the return on investment in the content business, and there is no index to evaluate cast & crew. The absolute number of TV ratings is steadily declining, but there is no substitute index yet. In this study, we tried to predict the relative popularity of the drama by designing the relative superiority of the individual drama viewership as the response variable and designing the relative superiority of the drama participants as the explanatory variables. We used various machine learning algorithms and added explanatory variables that were found to be useful in previous studies. As a result, with properly combined explanatory variables, a high prediction accuracy of 84% is obtained. In this study, we intend to promote the investment efficiency of the entire contents industry by predicting the relative popularity of the contents.

The most important thing in digital transformation is SW technology. However, many companies are having difficulty securing SW technology and manpower. In particular, it is reported that the shortage of SW manpower will increase further. The government is carrying out manpower training policies and many support projects to resolve SW manpower supply and demand policies, but accurate predictions of demand and supply of the software industry are essential for these policies to be effectively established. Therefore, this study developed a simulation using a system dynamics methodology that can perform dynamic structural analysis to resolve the supply and demand imbalance in the software industry. System dynamics is appropriate to find the cause and policy alternatives from a dynamic perspective on the imbalance in manpower supply and demand in the software industry. In detail, the U.S. Bureau of Labor Statistics (BLS) methodology was used to develop a prediction model for manpower demand and supply in the software industry, and scenario analysis was performed to derive policy implications.

본(本) 연구(硏究)에서는 인력계획(人力計劃)을 위한 인력필요량(人力必要量) 예측(豫測)에 초점(焦點)을 맞추기보다는 인력공급전망(人力供給展望), 인력수요분석(人力需要分析), 수급간(需給間) 상호관계(相互關係)등에 주목함으로써 고등교육제도(高等敎育制度)의 개혁과제(改革課題)를 도출(導出)하고자 하였다. 인력공급(人力供給) 측면에서는 2000년대 고졸자의 격감(激減)을 전망(展望)하고 이에 근거(根據)하여 대학교육(大學敎育)에 대한 초과수요(超過需要)를 전제로 하였던 규제위주(規制爲主)의 교육제도(敎育制度)의 근본적인 변화(變化)가 요구됨을 보인다. 인력수요(人力需要) 측면에서는 우리 경제(經濟)가 지식집약경제(知識集約經濟)로 이행(移行)함에 따라 고등교육(高等敎育)의 양적(量的) 팽창(膨脹)보다는 질적(質的) 향상(向上)이 보다 요구되고 있음을 논의한다. 또한 수급간(需給間) 상호관계(相互關係)에도 주목하여 직업기술(職業技術) 고등교육기관(高等敎育機關)과 기업(企業)을 연계(連繫)하는 네트워크가 구축(構築)되어야 함을 강조(强調)한다. 이러한 인력수급분석(人力需給分析)을 바탕으로 대학(大學)의 경쟁여건(競爭與件) 조성(造成)과 직업기술 고등교육의 산(産) 학(學)네트워크 구축(構築)을 위한 교육개혁(敎育改革)의 기본과제(基本課題)를 제시(提示)한다.

To plan a software project, the manager (1)make a work breakdown structure (WBS), (2) estimate efforts for each task, (3) assign employee to each task, and (4) estimate overall schedule. When software project becomes complicated, the possible combination of WBS, effort, and employee assignments dramatically becomes larger. Software planning tool can help software project managers to deal with this complexity. In this research, we discuss with a group of experts who work in software industry, to elicit practical requirements that should be considered in the software planning technique. Considering these requirements, we develop a software project planning tool APP (Automatic Project Planner) which provide effort estimation based on historical knowledge data and automatic human resource allocation. Our technique can be the basis of reasonable and practical software project planing.
