Company A's core competency is IT internet security services. The Web diagnosis team analyzes the vulnerability of customer's internet web servers and provides remedy reports. Traditionally, Company A management has utilized a simple table format report for resource planning. But these reports do not notify the timing of human resource commitment. So, upper management asked its team leader to organize a task team and design a visual dashboard for decision making with the help of outside professional. The Task team selected the web security diagnosis practice process as a pilot and designed a dashboard for performance evaluation. A structural design process was implemented during the heuristic working process. Some KPI (key performance indicators) for checking the productivity of internet web security vulnerability reporting are recommended with the calculation logics. This paper will contribute for security service management to plan and address KPI design policy, target process selection, and KPI calculation logics with actual sample data.

A severe problem in VE study of a project is to reduce value due to loss of performance, caused by focusing on cost reduction. Also a lack of understanding performance concept, no trial VE workshop as well as cost saving-based policy have not satisfied customer needs. A efficient VE job plan for especially large scale railroad construction project is proposed in this study. This study developed a more objective performance evaluation system for value engineering study of mega projects and suggested a systematic process of performance quantitative analysis for value improvement. The proposed performance measurement method would be very useful for better communication and consensus between decision makers and VE team.

It is practically very important in multi-criteria long-tenn IRP process to develop the set of candidate resource plans that meet following two conditions. First, the number of resource plans should not be too large for computer job. Second, the unknown best plan should exist among the set of candidate plans. In this paper, several novel procedures are developed. The main idea of the procedures is the two-stage approach. The first stage is to find the set of feasible resource capacity mixes in given target year(s). And, the second stage is to find the set of alternative paths of resource options for each resource mix determined in the first stage.

Two important concepts in VE are "function" and "cost." Cost can be expressed quantitatively. Unlike cost, the function can only be expressed qualitatively. Thus, to accurately evaluate the performance in VE analysis, it is required that the functional aspect should be considered a qualitative one. This study suggests a procedure of function oriented evaluation which can evaluate function enhancement of a VE proposal more logically and objectively. To conduct this study, problems were induced via case analysis, and solutions were found. In addition, the existing simple evaluation procedures were corrected, and a function enhancement evaluation procedure via function classification was suggested. For function classification, the use of the concepts, which were "intended function" and "additionally obtained function," was suggested. Function oriented evaluation procedure to VE proposals which is suggested in this study is expected to be a great help in treating valuable functions through VE job plan.

Construction management requires decision-making skills. Main approaches to training construction management students are: (1) analyzing sample situations involving decision-making; and (2) teaching logical decision-making procedures. The absence of 'pressure' factors in these approaches has significant impacts on the success of the training. The approaches also lack 'dynamic' effects that help create a spontaneous plan for construction projects where unforeseen changes and interruptions may occur. To minimize the adverse effects of the existing approaches, this paper proposes a framework for developing a web-based training system. The application is delivered as a game involving decision-making on the student's part in response to developments at the job-site, and where one student competes against another in an attempt to simulate a real-world scenario.

The duration of a construction project is not only a key element for taking a new order, but also a strict yardstick to determine certain project successful or not. However, since construction project is basically outdoor job and most of the activities are proceeded out-air, no matter how the schedule plan has been established accurately, actual project proceeds due to the weather condition, beyond anyone's control. In this paper, the functional relationship between work productivity rate and weather elements is suggested by regression analysis. Difference of the relationship and influence of weather due to the seasonal group are also revealed. With these results, by simulating actual weather data and generating weather forecast through historical data, more accurate schedule would be obtained.

Rehabilitation has emerged in recent years as major topic for the handicaped in industrial accident compensation insurance(IACI). Specially social support helps the handicaped adjust themselves psychosocially to handicap. This study was conducted to examine different contents and perceived social support, and provide guidlines for specific and proper rehabilitation for the handicaped of IACI. This study is a descriptive study which were collected through two phases using structured questionnaire. In the first stage, surveys were performed via telephone interviews. In the second stage, surveys were performed via home-visit subjects in the first stage included the handicaped of IACI. Finally data were collected from 338 subjects and analyzes by SPSS/PC+10. The instruments of this study were the perceived social support scale which developed by Lee(1996). These scales in the form of 5-point Likert type, consists of 20 items, including 3 subscales of emotional support, informational support, instrumental support. The mean score of social support was 57.2, emotional support 21.0, informational support 21.2 and instrumental support 15.2. The mean of depression for psychosocial factors is 37.5. Threre were significant differences in total perceived social support; age, job status, handicaped degree in IACI, post-traumatic complication and use of instrument. Emotional support was significant differences; age, number of dependent family, job status, handicaped degree in IACI, use of instrument and depression. Informational support was significant differences; job status, posttraumatic complication, use of instrument and depression. Instrumental support was significant differences; sex, job status, handicaped degree in IACI, use of instrument, and depression. The current system of the Labor Welfare institute is not appropriate for solving health problems of the handicaped in IACI. Therefore, it is necessary to develop the plan which can provide the handicaped in IACI high-quality rehabilitation services, so that they must use those services in the community without being dependent on hospitals. This study proposes home visit nursing services as the way to provide various health services within community for the handicaped in IACI.

The purpose of this study is to analyze the dental hygienists' overall performance in operative restoration and the clinical performance in operative restoration according to dental hygienists' career and to provide basic data for establishing the appropriate range of dental hygienists' work. Subjects of this study are 339 dental hygienists working at dental clinic and hospital nationwide, selected by their working place, career, type of clinic, and location of clinical institution. The distribution of people who responded to the survey shows that 81 belong to beginner level(less than 2 years since entering clinic), 115 intermediate level(2 to 3 years since entering clinic), 81 higher level(4 to 5 years since entering clinic) and 62 advanced level(more than 6 years since their entering clinic). In terms of the types of clinical institution, 178 belong to dental clinics and 161 belong to dental hospitals. The survey used in this study are focused on perception about clinical performance in operative dentistry and adequacy of the work. Operative dentistry consists of operative restoration and endodontic therapy. The operative restoration consists of 15 categories such as patient welcoming, examination and diagnosis, planning of treatment, anesthesia, control of moisture, cavity preparation, pulp protection, matrix band application, amalgam filling, resin filling, glass ionomer cement filling, abrasive strip removal, rubber dam removal, bite check and polishing, patient education, and arrangement. The reliability was Cronbach's Alpha .9453. SPSS 10.0 for Windows was used to analyze the responses. One way ANOVA was utilized to verify the differences in the dental hygienists' job performance in operative restoration and their job performance according to career. When significant difference was found. Duncan multi comparison post hoc was done. To sum up the results of this study, patient welcoming look the first place in the operative restoration. It was followed by patient education, examination and diagnosis, introducing treatment plan, resin filling, glass ionomer cement filling, amalgam filling, bite check and polishing, anesthesia, pulp protection, control of moisture, abrasive strip removal, cavity preparation, matrix band application, rubber dam removal, and anesthesia. In terms of the clinical performance by career, there were significant differences in 19 activities such as medical eraluation, oral examination, patient charting, intra oral readio graphs, firm developing fixing mounting, curing light gun, education of attention content after operation. Based on the results of this study, the specific range of operative restoration for dental hygienists should be focused on providing basic data for dentists' diagnosis, alleviation of fear and aching accompanied by injection and anesthesia, data providing for dentists' decision of anesthesia degree, and maximization of control of moisture.

건설교통부에서는 예산절감을 위해 토석정보시스템을 운영하고 있으며, 시스템 운영에 기본적으로 고려되어야 할 사항은 원지반의 토량을 기준으로 산정되는 토량 변화율인 토량환산계수의 정확한 적용이다. 토공사의 절성토량의 균형, 사토장 및 토취장의 계획은 공사비와 직접적인 관계를 가지고 있기 때문에 정확한 토공량 산정 및 효율적인 토공유동이 무엇보다도 중요하다고 할 수 있다. 그러나 현장에서의 비합리적인 토량환산계수의 적용으로 토공유동이 효과적이지 못한 점이 있으며, 정확한 공사비 산정 및 투입에도 지장을 초래할 수 있다. 이와 같이 효율적인 토공유동계획은 토공량 산정의 정확도에 기인한다고 할 수 있으며, 정확한 토량환산계수의 적용이 토공량 산정에 절대적이라 할 수 있다. 본 연구에서는 대규모 토공사가 실시되는 현장을 대상으로 대상지 내의 임의지점 절 성토부를 굴착하고 굴착 전후 및 다짐후의 체적을 사진측량기법 및 레이저스캐닝기법으로 정밀한 수치표고모형을 제작하여 토량환산계수를 산정하고, 동시에 절 성토부 건조밀도시험을 통해 산정되는 토량변화율의 결과값과 비교 분석하여 신뢰성 있는 토량환산계수의 산정방법을 결정하고자 한다.
