The burden of injury is widely considered to be very severe in our society. Nonetheless, we don't have enough data for injury surveillance. The objective of this research is to select and supplement CORE DATA for injury surveillance. For this purpose, this study had analyzed the literature such as the Quality Assessment Report about 'Causes of Death Statistics', 'Health Insurance Statistics' and 'Hospital Discharge Injury Surveillance' according to the six dimension of Statistics Quality. The analysis result is that 'Cause of Death Statistics' and 'Health Insurance Statistics' have the usefulness as the CORE DATA for injury surveillance. But there is a significant shortcoming in the Health Insurance Statistics, which is that there is a lack of the data about the external causes of injury. For supplementing the defect, this study proposes the system that the medical institutions should obligatorily report the external causes of injury when claim National Health Insurance Medical Care Expenses. As the results of this system, we can expect 'Establishing of Injury pyramid', 'Data Connecting with the National Pension' and 'Improving the Promptness of Injury Data'. And we expect the follow-up study for the realization of this system.

KS F 2782 (for shotcrete accelerators) standard cross-section of tunnel construction or repair is a reinforcement used in the field of shotcrete accelerators as a criterion in assessing shotcrete performance. Thus, KS F 2782 by standard accelerator will determine the nature of the product of concrete accelerators that will be used to record variations in the product roles, through determination of the quality of the experimental method to identify only the quality of the many variables that exist. This evaluation standard has so far distinguished accelerator products in indoor experiments that do not meet quality standards but were mostly for an on-site accelerator mixed with the shotcrete after being quite satisfied with the level of quality in a certain number of products. This observation is derived from the results of an indoor experiment considered to verify whether the site is suitable for indoor experiments, and whether its actual location in the city is relevant to the accelerator quality, to find a way to test if it fits. This study centers on the material conditions of the shotcrete accelerator and a variety of experimental results, and used the Gilmore needle to compare the compressive strength and KS F 2782 specification of the accelerator as a means to ensure product quality conformity analysis and for further research experiments. In conclusion, a portion of KS F 2782 standard that fixes the problems that can be resolved from the ground up as a whole is not a review for the domestic reality. As an indoor experiment to ensure uniformity in the field when applied in a sufficient correlation, complement must be in place.

The frequent occurrence of structural failures at building construction sites in Korea has underscored the critical role of rigorous oversight in the inspection and management of construction projects. As mandated by prevailing regulations and standards, onsite supervision by designated supervisors encompasses thorough documentation of construction quality, material standards, and the history of any reconstructions, among other factors. These reports, predominantly consisting of unstructured data, constitute approximately 80% of the data amassed at construction sites and serve as a comprehensive repository of quality-related information. This research introduces the SL-QPA model, which employs text mining techniques to preprocess supervision reports and establish a sentiment dictionary, thereby enabling the quantification of quality performance. The study's findings, demonstrating a statistically significant Pearson correlation between the quality performance scores derived from the SL-QPA model and various legally defined indicators, were substantiated through a one-way analysis of variance of the correlation coefficients. The SL-QPA model, as developed in this study, offers a supplementary approach to evaluating the quality performance of building construction projects. It holds the promise of enhancing quality inspection and management practices by harnessing the wealth of unstructured data generated throughout the lifecycle of construction projects.

Physical evaluations provide the basis for an objective and quantitative analysis of the image quality. Nonetheless, there are limitations in using physical evaluations to judge the utility of the image quality if the observer's subjectivity plays a key role despite its imprecise and variable nature. This study proposes a new method for objective and quantitative evaluation of image quality to compensate for the demerits of both physical and subjective image quality and combine the merits of them. The images of chest phantom were acquired from four digital radiography systems on clinic sites. The physical image quality was derived from an image analysis algorithm in terms of the contrast-to-noise ratio (CNR) of the low-contrast objects in three regions (lung, heart, and diaphragm) of a digital chest phantom radiograph. For image analysis, various image processing techniques were used such as segmentation, and registration, etc. The subjective image quality was assessed by the ability of the human observer to detect low-contrast objects. Fuzzy integral was used to integrate them. The findings of this study showed that the physical evaluation did not agree with the subjective evaluation. The system with the better performance in physical measurement showed the worse result in subjective evaluation compared to the other system. The proposed protocol is an integral evaluation method of image quality, which includes the properties of both physical and subjective measurement. It may be used as a useful tool in image evaluation of various modalities.

The purpose of this experimental research is to investigate the properties of workability and strength of the concrete containing admixtures such as silica fume, fly ash, ground granulated blast-furnace slag, and rice husk ash. For this purpose, the workability and the strength of the concrete containing each admixture were tested and analyzed according to the unit weight of binder and the replacement ratio of each admixture. As a result, considering their workability and strength, the existence of minimum binder weight and optimum replacement ratio of concrete containing admixture to plain concrete were obtained for each admixture.

Recently, construction industry shows active expansion in overseas construction market. But the active work limited in construction work, on the other hand, design-drawing work is evaluated shortage of competitive power. So this study aim to improve the competitive of 'domestic design-drawing work'thorough objective evaluation. Objective evaluation is consist of 'design attribution'. Design attribution is based on the execution drawing and complement by existing reasearch, expert interview. And then, list up the 'design attribution' evaluation list to carry out a survey targeting hands-on worker. Survey is consist of 'Likert 5-point scale, FMEA method'. As a result, construction company and design company show different opinions in both relative position evaluation and importance evaluation.

인터넷은, 전화로 대변되는 과거의 정보통신 서비스와는 달리 사회 전반에 막대한 영향력을 행사하는 서비스로 발전하였다. 인터넷에 대한 의존도는 향후 모든 정보통신서비스가 인터넷을 기반으로 제공되는 All-IP 디지털 컨버전스 시대에 더욱 더 심화될 것이다. 이 경우 오늘날의 인터넷보다도 QoS(Quality of Service)에 관한 이슈가 더욱 중요해질 것은 자명하다. 이러한 배경에서 ITU(International Telecommunication Union)나 IETF(Internet Engineering Task Force)등의 국제표준화 기구에서 차세대 인터넷 (Next Generation Network, NGN)에 대한 QoS 문제를 연구하고 있다. 그러나 이들 국제기구는 주로 기술공학적인 측면에서 QoS 문제에 접근하고 있어서 현실적으로 완전한 대안을 제공하지는 못하고 있다. 즉, 인터넷 산업의 특성상 사업자간 끊김없는 연동(seamless inter-operations)과 협력이 필수적인데, 이는 기술공학적 측면보다도 비즈니스 및 정책적 관점에서 다루어져야 되기 때문이다. 통신 사업자 및 벤더(vendor)의 글로벌 컨소시엄으로 출발한 TMF(TeleManagement Forum)나 QuEST Forum 등의 역할이 중요해지는 이유가 여기에 있다. 이미 이들 단체는 사업자간 합의에 의해 자발적으로 구축한 NGOSS 및 TL9000 인증시스템을 바탕으로, 망사업자를 비롯한 서비스공급자 및 벤더 등과의 원활한 협력관계를 구축하는 글로벌 de facto 표준을 마련한 바 있다. 본 연구에서는 QoS 보장을 목표로 하는 차세대 인터넷(NGN)의 현실적 성공 가능성을 높이기 위한 글로벌 표준화 노력을 소개하고 이들을 비교/검토한다. 특히, ITU 및 IETF 등의 NGN 개발계획을 비즈니스/정책점 관점에서 보완할 수 있는 TMF와 QuEST Forum의 접근법을 고찰하여, All-IP 컨버전스 환경에서의 QoS 이슈에 시사하는 바를 살펴본다.
