The National Health Insurance (NHI) has been the main body of health care system in Korea for the last 30 years since the NHI was founded. However, the inefficient management and strong regulations of the NHI have hindered the development of health care industry. The establishment of the MB government, whose interest lies on economic growth rather than equity, is expected to help the health care services gain a momentum. The essential measures that can step up public health care services overall are the following: the introduction of competition within NHI, the activation of private health care insurance, and the allowance of for-profit hospital. The private-public mix with market mechanism would level up the health care service for the public.

In this paper, we consider to the adjustment weighting procedure in the two phase sampling scheme. In general, the unit nonresponses may be occured in the final survey operation. When the unit nonresponse be generated in survey, it is able to use the auxiliary variable for estimating of interest variable. In this viewpoint, we use the two kinds level of auxiliary variable, $X_{1k}$ and $X_{2k}$ for the calibration procedure. We proprose the two-step Newton's method in the calibration estimation procedure for the two phase sampling.

본 논문에서는 광역 ATM 망에서 인터넷 서비스를 제공하기 위하여 입력 소스 트래픽의 QoS 등급에 기초한 라우터 시스템에 적용되는 다양한 스케줄링 알고리즘들을 분석하고 서비스 특성에 따라 QoS 요구사항을 보장할 수 있는 새로운 스케줄링 알고리즘을 제안한다. 이를 위하여, 인터넷망에서의 패킷 다중화기의 요구사항을 살펴보고 실시간 서비스제공을 위한 패킷 다중화기의 기능 구조와, 다양한 QoS를 만족시키기 위한 스케줄링 알고리즘을 설계한다. 마지막으로 모의 실험을 통해 평균 지연 시간 및 망 자원 활용의 공평성 측면에서 알고리즘의 성능을 고찰한다.

Dietary life of Korean population was greatly improved by the increased food production, enlarged food processing and betterment of food distribution system during the last three decades. On the other hand, food pollution issues have arisen from the increased use of chemicals and advancements in analytical techniques and toxicological information. The health risk of hazardous substances in Korean diet was estimated to be in the decreasing order of heavy metals>pesticide residues>food additives>mycotoxins>radionuclides>PCBs whereas consumers do not recognize it in the same order. It is needed to evaluate the food safety more accurately based on scientific evidences and to adopt reasonable regulatory measures in Korea for the benefits of people's health and national interest.

This paper proposes an automatic liver segmentation method using improved partial histogram threshold (PHT) algorithms. This method removes neighboring abdominal organs regardless of random pixel variation of contrast enhanced CT images. Adaptive multi-modal threshold is first performed to extract a region of interest (ROI). A left PHT (LPHT) algorithm is processed to remove the pancreas, spleen, and left kidney. Then a right PHT (RPHT) algorithm is performed for eliminating the right kidney from the ROI. Finally, binary morphological filtering is processed for removing of unnecessary objects and smoothing of the ROI boundary. Ten CT slices of six patients (60 slices) were selected to evaluate the proposed method. As evaluation measures, an average normalized area and area error rate were used. From the experimental results, the proposed automatic liver segmentation method has strong similarity performance as the MSM by medical Doctor.

This article proposes to examine how the study of failure differs from other technical subjects, and how to turn failure experiences to one's advantage. The authors surveyed the properties of failures in PBL (Project Based Learning) and also examined students' interest and understanding of failure, after introducing failure examples. To investigate how students communicate failure experiences to third parties, reports of the failure experience in PBL were evaluated. From above mentioned surveys, we get the following results. The typical causes of failure in educational institutions are lack of skill in manufacturing and inadequate planning, which conversely are minor causes of failure in the industry. A knowledge database on failure, employed commonly in industry, is not effective in PBL, because projects in educational institutes are usually changed every year. Case studies in failure can be approached from many points of view including causes, processes, effects and safety measures. While teachers should emphasize the notable points in the failure examples in introducing examples of specific topics in machine design, teachers should explain the multiple aspects in the failure examples to educate students about the complexity of actual accidents.

In this paper, we report the public IT policy case results to restructure informatization level indices for small and medium sized enterprise(SME). The indices restructuring project was initiated by TIPA with the group of experts during 2011, and the newly amended indices was employed as the formal instrument to measure SME informatization level. The critical drivers to reform the indices include simplification for more accurate measurement of SME informatization level, reshaping key representative indices of smart IT to better publicize SME's interest toward advanced IT, and systematic reconfiguration of performance measures which reflect business performance enhancement effect through IT investment. Indeed, the IT performance indices are unified to incorporate the instrument for general SME informatization level survey and IT adoption subsidy's effectiveness appraisal. The procedures and details of logic illustrated in this paper provides useful insight for successful implementation of SME informatization as well as for the better policy deployment of IT subsidization for SMEs.

The traditional process capability indices Cp, Cpk, Cpm, $Cpm^+$ have been used to characterize process performance on the basis of univariate quality characteristics. Cp, Cpk consider the process variation, Cpm considers both the process variation and the process deviation from target and Cpm+ considers economic loss for the process deviation from target. In manufacturing industry, there is growing interest in quantitative measures of process variation under multivariate duality characteristics. The multivariate process capability index incorporates both the process variation and the process deviation from target or considers expected loss caused by the process deviation from target. This paper proposes multivariate capability index based on the expected loss derived from multivariate normal distribution.

The development of society and the desire for a happy life for the safety of the public's interest in higher things of the increased body, Bain safety awareness and safety of repeated disasters without action to prevent the spread will have no choice but to tough it will also harm. Safety education training from an early age desperately needed for safety's why. Elementary Middle High School students' characteristics and level of safety for your knowledge, skills, attitudes and habits in order to train to teach in any manner whatsoever any information about the study will assess the need.

The purpose of this study was to examine the effects of Korean traditional music education for young children on the development of musical attitude and rhythmic sense of young children. The subjects were 42 four or five-year-old children enrolled in two classes of a public kindergarten. Half were in the experimental and half were in the control group. Instruments were "Music Interest Test for Young Children" (Kim, 2000), "Musical Attitude Rating Scale for Young Children" (Ahn & Han, 1999) and "Primary Measures of Music Audiation" (Gordon, 1986). The procedure included pre-test, treatments and post-test paradigm. Experimental group had Korean traditional music activities three times per week, including listening, appreciation, singing, playing traditional instruments and creative movement. The control group was merely provided with materials related to the Korean traditional music. Data was analyzed by t-test. Results indicated significant differences in music attitude and rhythmic sense between the experimental group and the control group.
