Recently, the demand for performance evaluation and management at the industrial or corporate level has been increasing. From this perspective, this study has developed indicators to measure and compare construction company performances and we have analyzed various characteristics of those indicators. Throughout our thorough qualitative and quantitative analysis we first identified a set of indicators for performance measurement. These indicators have been shown to meet the requirements of validity, measurability, and comparability. Second, we calculated the performance index of construction companies by applying weightings of the performance categories. Then we performed correlation and regression analyses using the calculated performance index and identified the basic cause-and-effect relationships, as well as the statistical characteristics of the performance index. Drawing on the results of the analytical processes identified in this work, we discuss future research to be conducted.

Although the methodological literature is replete with advice regarding the development and validation of multi-item scales based on reflective measures, the issue of index construction using formative measures has received little attention. The aim of this paper is to enhance researchers' understanding of formative measures of high-order factor and assist them in their index construction efforts. This article is also to provide some insights into the nature of formative indicators for researchers to reach an informed choice as to the appropriate high order formative measurement model for their needs. We first provide a brief background on formative indicators, drawing from the limited and fragmented literature on the topic. Next we give an example of constructing an index based on actual survey data and highlight the procedures used to assess its quality. We conclude the article with some thoughts about the use of indexes in empirical studies.

As the entrepreneurial ecosystem turns out to be a leading factor in improving nation's entrepreneurship, many studies are underway in the country to develop the start-up ecosystem. Although the entrepreneurial ecosystem is receiving attention as an essential factor for the nation's economic growth as well as entrepreneurship due to its inter-relationship with start-ups, government agencies and investors, criticism of measurement indicators has been increasing due to the different institutional and political contexts of each country, including the various definition of start-up ecosystem. In this study, we develop indicators that are suitable for domestic conditions in Korea and that can measure the level of start-up ecosystems in each regional level. FGI and Delphi surveys by scholarly experts in each field of start-ups & entrepreneurship were conducted to verify how well existing indicators fit the domestic situation and to develop indicators that can measure the local entrepreneurial ecosystem in Korea through close examination. As a result, the local entrepreneurial ecosystem consisted of three to four sub-components and 38 sub-components, each consisting of seven indicators, including Policy, Investment, Culture, Market, Human Capital, Support and Knowledge. It is expected that this research will be used to diagnose local start-up ecosystems and to propose discriminatory policies that can complement regional strengths and weaknesses.

A datawarehouse which extracts and saves the massive analysis data is used for marketing and decision support of business. However, the datawarehouse has the problem of increasing the process time and cost as well as has a high risk of process errors because it integrates vast amount of data from distributed environments. Thus, we propose a metrics for measurement in the area of productivity, process quality and data quality. Also through the evaluation using the proposed metrics, we show that our proposal provides productivity enhancement and process improvement.

전통적 재무제표가 기업의 재무적인 성과 측정에만 초점을 맞춘다는 한계를 극복하기 위한 방법으로서 BSC(Balanced Scorecard)가 제시되었다. BSC는 KPI(Key Performance Indicator)들의 상관관계가 명확하고 논리적이라는 장점 때문에 정부 및 기업의 다양한 분야에서 적용되어왔다. 이러한 BSC는 KPI를 통해 측정된 값의 비교에 대한 고려를 하고 있지 않으므로 다수 조직의 성과를 비교하기에 어려움이 있다. 조직의 효율성을 rPfidd적으로 나타내는 여러 기법 중, 경영과학 기법을 이용한 DEA의 경우 다수의 측정 지표를 단일의 통합된 성과 측정 지표 (Aggregate Performance Measure)_로 나타낼 수 있다는 장점이 있으나, DEA에 고려되는 입력 및 출력의 개수에 제한이 있으며 다수 조직의 분석에 사용해야 한다는 단점이 있다. 본 연구에서는, 재무적인 요소와 비재무적인 요소를 포괄하여 조직간의 효율성을 비교하기 위한 벙법으로서, DEA를 이용한 효율성 평가에 조직의 성과측정 기법인 BSC가 제공하는 KPI 간의 노릴적 인과관계(cause-and-effect relationship)와 측정 지표를 이용하는 방법으로 CDB(Combined DEA and BSC methodology)를 제안한다. 이를 위하여 BSC 정보 비교 가능한 형태로 바꾸는 방법을 제시하며, 기존 DEA가 지니는 입력 및 출력 변수 개수의 증가에 따른 효율성의 구분능력의 감소와 관련된 한계를 극복할 수 있는 방법을 제시한다.

하구 감조부에서의 유량측정은 수문관측매뉴얼에 의하면 일반하천의 유량측정과 같은 원칙으로 실시하며, 일반 유량측정보다 신속하게 측정하고 유속과 유량을 연속적으로 측정해야 하고 조석을 잘 고려하여 관측계획을 수립하여야 하고 측정장비는 가급적 유향, 유속계의 기록부가 내장된 장비를 이용하도록 제안하고 있으며, 현실적으로 감조하천에서 유량측정은 많은 어려움이 따른다. 최근 우리나라에서 하천유량의 효율적인 측정을 위해 초음파유속계나 지표유속법과 같은 실시간 하천유량측정 방법이 도입되고 있다. 본 연구에서는 이러한 자동유량관측이 감조하천에 가능하도록 실시간 유량관측 시스템을 개발하여 운영하였다. 조석의 영향을 받는 한강대교지점에 도플러방식 초음파유량계를 회전체에 탑재한 자동유량측정장치를 남 북단 하천에 각각 1대씩 설치하였다. 본 시스템을 운영한 결과 무인 자동 연속 정밀관측이 가능하였으며, 1회 유속측정에 소요되는 $2{\sim}3$시간을 $5{\sim}6$분으로 단축시켰다. 이를 기반으로 감조하천에서의 자동유량관측이 가능하고 지표유속법을 도입하여 정확도를 높일 수 있는 유량산정기술을 개발하였다.

As all industries field has changed very quickly, the field of construction faces in many changed. It is the representatively change that focus on the growth of quality level than increase of the quantity in construction. Whether the project successes or not is related to the survival of the company and it is necessity that we need performance measurement indicators to complete the project successfully. The domestic construction company considers overbearingly the cost-performance indicator in executing a project so far. It is rare of studies that suggest the methodology of more deeply measurement and analysis about the each project itself. The performance measured methodology based on Lean Construction is linked with the each project performance measurement methodology. This methodology uses three indicators such as the reliability, effectiveness and productivity at the sane their measuring whether each task is completed at the point of work. The measurement on the three performance indicators measure and evaluate whether the task is completed on the focus of construction duration. The research suggest the work plan reliability and weight of the performance measurement methodology based on the Lean Construction and the three considerately in the scope of measurement. If the suggestion is considered fully, we can indicate more objective and accurate construction project performance measurement indicators based on Lena Construction.

Purpose : The objectives of this study was to evaluate the correlations between the indices of insulin sensitivity using fasting glucose and insulin level, and the body fat mass measured by bioelectrical impedance analysis(BIA) and dual energy X-ray absorptiometry(DEXA), and to determine the clinical usefulness of insulin sensitivity indices when obese children were followed up. Methods : In this study, 28 simple obese children and adolescents were included. Anthropometric data including body weight, height, obesity degree(OD), body mass index(BMI), and waist-to-hip ratio were collected and then body fat mass was measured by using BIA and DEXA. For metabolic data, 12 hour fasting serum glucose, insulin and lipid profiles were measured and indices for insulin sensitivity(G/I ratio, $log_{insulin}$, HOMA-IR, $log_{HOMA-IR}$, QUICKI) were calculated. Results : BMI had a higher correlation with insulin sensitivity indices than OD(G/I ratio, -0.463 vs -0.209; $log_{insulin}$, 0.417 vs 0.196; HOMA-IR, 0.301 vs 0.238; $log_{HOMA-IR}$, 0.403 vs 0.198; QUICKI, -0.451 vs -0.224). But OD had a higher correlation with body fat mass measured by BIA and DEXA than BMI(BIA, 0.612 vs 0.316; DEXA, 0.667 vs 0.512). The G/I ratio was correlated with body fat mass in BIA(r=-0.420, P<0.05) and DEXA(r=-0.512, P<0.01), percentage of body fat(percentage of fat) in BIA(r=-0.366, P<0.05) and DEXA(r=-0.449, P<0.01). HOMA-IR was only correlated with body fat mass in DEXA(r=0.341, P<0.05). Conclusion : This study revealed that G/I ratios had a statistically significant correlation with anthropometric obesity indices(OD and BMI) and also had a correlation with both body fat mass and percentage of fat. These results suggest that G/I ratios could be used as useful index when obese children and adolescence are followed up.

The purpose of this study is to investigate national fire safety consciousness (FSC). A FSC survey would help with proper fire safety policy. Indicators to define and measure efficiently the FSC were broken down into five areas: prevention, alarm, evacuation, extinguishing, and damage expansion prevention. The indicators were developed using Parasuraman's method based on domestic and foreign research materials and meetings with experts. FSC was surveyed using the indicators on Gallup Korea. The results of the survey analysis show that evacuation is lowest, followed by extinguishing, alarm, prevention, and damage expansion prevention.
