  • 전통적으로 소프트웨어 프로젝트는 납기지연, 예산초과, 높은 결함율 등으로 타 산업분야의 프로젝트에 비해 매우 높은 실패율을 기록하고 있는 것으로 알려져 있다. 이 같은 소프트웨어 프로젝트의 실패원인에 대한 많은 연구결과는 소프트웨어가 갖고 있는 범위와 요구사항 정의의 어려움, 비가시성으로 인한 초기견적의 부정확성, 역시 가시성의 부족으로 진행상황파악의 어려움에 따른 진척관리의 애로, 더욱 큰 문제는 변경의 용이성과 변경에 대한 추적의 어려움 등을 지적하고 있다. 실패한 프로젝트들의 내용을 보면 대부분 계획의 부정확성이나 위험에 대한 대처의 부족 또는 진행 중 발생하는 변경에 대한 통제의 실패에서 찾아 볼 수 있다. 정확한 예측과 위험 예방 그리고 효과적인 통제대책이 소프트웨어 프로젝트를 성공으로 이끄는 3두 마차라는 지적이다. 정확한 예측의 핵은 프로젝트 산출물인 제품에 대한 정확한 규모측정에 있고, 위험 예방은 복잡도가 높거나 불확실성이 높은 컴포넌트의 자원소요에 대한 예측과 이에 대한 준비의 소홀에서 찾을 수 있으며, 효과적인 통제대책은 프로젝트 관리 프레임워크가 튼튼하지 못하거나 이의 준수를 위한 노력의 결핍에서 찾을 수 있을 것이다. 본 논문에서는 이 3두 마차 중 가장 근간이 되고 시발점이 되는 제품의 규모에 대한 예측에 초점을 맞추어 규모측정에 가장 합리적이고 객관적이며 실용성이 높다고 현재 국제적으로 높은 평가를 받고 있는 기능점수를 프로젝트 관리에 어떻게 활용해야 프로젝트를 성공시킬 수 있을 지의 방법에 대한 검토 결과를 제시고자 한다.

  • Objective : This study is purposed to suggest basic data of developing program preventing Herpes zoster by analysis of related variables for adults over 50 years old. Methods : Data had been collected by 225 adults over 50 years old who participated in health program in B city, interested program of welfare service center in C city and community residence through self-administered questionnaire from $15^{th}$ June to $15^{th}$ July 2016. The collected data was analyzed by IBM SPSS statistics v.18 and AMOS v.18. Results : Based on the verification of model by the results of the study, ${\chi}^2=365.785$(df=193, p<.001), $CMIN/DF({\chi}^2/df)=1.90$, GFI=0.88, AGFI=0.84, NFI=0.88, TLI=0.93, CFI=0.94, RMR=0.07, RMSEA=0.06, The action of Herpes zoster preventive behavior and perceived behavior control for adults over 50 years old made direct influence to the Herpes zoster preventive behavior and the attitude of preventive behavior showed the largest total effect. Conclusions : In conclusion, for improving action of Herpes zoster preventive behavior for adults over 50 years old, it is important to induce change of attitude about Herpes zoster preventive behavior. Also, the development and strategy of education program, which can improve action of Herpes zoster preventive behavior, are necessary through emphasizing perceived behavior control about Herpes zoster preventive behavior.

  • This study was conducted to prove the effectiveness of home-linked indirect smoking prevention education in early childhood in improving the awareness, skills, attitudes and willingness to protect themselves from smoking. 208 5-year-old children were recruited from three kindergartens located in Seoul and Gyeonggi-do. Children in the experimental group received home-linked indirect smoking prevention education. Children in the comparative group, received indirect smoking prevention education in kindergarten. Children in the control group received general health education. The results revealed that all groups showed significant differences between pretest and posttest in awareness of second-smoke, attitudes and willingness to stop smoking. However, the skills to protect oneself from second-smoke showed a significant difference in the experimental group and the comparative group. The values of changes among the groups showed high increases in the order of experimental, comparative, and control groups. This shows that home-linked education had considerable positive effects on indirect smoking prevention.

  • The purpose of this study was to develop an education system to protect elementary school students from inappropriate information and verify the effect of the program. It was deemed necessary that an education system be developed for the cultivation of appropriate information selection and self-censorship of inappropriate Internet information. To this time, however, schools have not placed great importance on this concept because of the lack of the documents and the teaching strategies. Our system gives support on three levels to a learning course according to collected documentation. The learner receives not only feedback activities and results from others and the teacher, but also counsel from the teacher about difficulties. The system implementing this methodology indicated that both the students' recognition of harmful information and their moral values were improved as the result of applying the system in a local elementary school.

  • Recently, crime prevention is away of important criminal justice policy and police activity also pursuit different change compare to the present times. After modern times, as get to know crime control change, eventually on the basis of experience that crime prevention is best way of crime control, what come out with new sight angle for the role of police is community policing. And emphasis points in police activity are variety of police activity, positive entry of community. In relation to this, we are learning crime prevention of the U.S.A and the program of community policing through crime prevention theory books that published in domestic. Then, there are misunderstanding possibilities that the programs which introduced relation books are doing someways all around the U.S.A In this research two cities san mateo county. california, of the U.S.A made a choice, and is going to search main crime present condition of these cities and really done community policing program or crime prevention program operation case.

  • 인구 밀집도가 높은 곳에서의 안전사고 대응과 이에 대한 예방을 위한 기술 및 해결 방안의 필요성이 증가하고 있다. 이를 위한 기존의 기술들은 지능형 CCTV 기반의 경고 알림을 울리는 방식과 스마트폰의 신호를 수집하여 유동인구를 측정하는 기술 등이 사용되고 있다. 그러나 군중 밀집 사고의 원인인 병목현상과 군중 난류 현상까지 대응하지는 못하는 문제점이 있다. 본 논문에서는 CCTV로부터 수집된 영상 정보만으로 딥러닝 영상인식 기술을 이용하여 병목현상이 일어나기 쉬운 출입구의 유·출입 인구 카운팅과 광장의 밀집도 분석을 디지털 트윈 기반으로 실시하고 이를 통해 위험 상황 발생 시 출입구의 통제와 대피를 위한 안내가 가능한 시스템을 제시한다. 제시하는 시스템은 유동 인구가 많고 인구의 급격한 밀집으로 인해 발생할 수 있는 안전사고의 예방과 이를 해결하기 위한 통제 및 안내를 위한 대처 방법으로 활용할 수 있다.

  • The purpose of this investigation was to examine the mediating effects of delinquent peers between attachment to parents, low self-control and adolescent deviant behaviors. After specifying a research model based on Gottfredson and Hirschi's general theory of crime and Hirschi's control theory of delinquency, the study analysed the model using structural equation modeling. The data for this investigation came from a sample of 2,448 Korean adolescents. The results showed the both measurement model and structural model had a good fit to the data and all paths of structural model were statistically significant. The main findings were the attachment to parents and low self-control had direct and indirect effects on adolescent deviant behaviors through delinquent peers. The implications for practical intervention and further research in the field of delinquency were discussed.
