  • 기존에 개발되어 활용되고 있는 평가지표는 비효율적 배점 구성과 실제 작은도서관 환경과 괴리된 평가항목 및 세부지표 그리고 작은도서관 정책 마련에 필요한 기초자료로서 가치 미비 등의 측면에서 개선할 필요가 있다. 따라서 피평가자인 작은도서관의 요구를 반영하여 정량평가에 의한 계량적 평가뿐만 아니라 작은도서관의 기본적 목적과 가치를 평가할 수 있는 정성적 평가를 포함하는 작은도서관 운영평가 지표(안)을 제안하였다. 제안한 작은도서관 운영평가 지표(안)은 평가방법 및 세부지표의 평가척도 다변화를 통해 작은도서관 자체 운영점검과 수준을 가늠할 수 있는 자기점검을 위한 평가가 되도록 하였다.

  • Purpose: To provide Diagnostic Criteria and Severity Evaluation Criteria of postpartum edema mainly complained by women directly after delivery. Methods: We analyzed Edema Index(ECF/TBW) analyzed by Body Composition Analyzer(InBody720) of 103 women directly after delivery who were delivered in Ob & Gy of Dongguk University Ilsan Hospital. Results: Mean value for Edema Index of 103 participants was 0.3527$\pm$0.0102, Minimum was 0.336, Maximum 0.388. From this Mean value and Edema Index distribution of participants, We suggest that we can diagnose more than 0.35 of Edema Index as Postpartum Edema, more than 0.35 and less than 0.36 as postpartum edema grade 1, more than 0.36 and less than 0.37 as grade 2, more than 0.37 as grade 3. Conclusion: This research is the first step for diagnostic criteria of postpartum edema, we suggest that diagnostic criteria of postpartum edema is more than 0.35 of Edema Index score. But this suggestion must be revaluated by additional research.

  • Background: To evaluate the facial asymmetry, three-dimensional computed tomography (3D-CT) has been used widely. This study proposed a method to quantify facial asymmetry based on 3D-CT. Methods: The normal standard group consisted of twenty-five male subjects who had a balanced face and normal occlusion. Five anatomical landmarks were selected as reference points and ten anatomical landmarks were selected as measurement points to evaluate facial asymmetry. The formula of facial asymmetry index was designed by using the distances between the landmarks. The index value on a specific landmark indicated zero when the landmarks were located on the three-dimensional symmetric position. As the asymmetry of landmarks increased, the value of facial asymmetry index increased. For ten anatomical landmarks, the mean value of facial asymmetry index on each landmark was obtained in the normal standard group. Facial asymmetry index was applied to the patients who had undergone orthognathic surgery. Preoperative facial asymmetry and postoperative improvement were evaluated. Results: The reference facial asymmetry index on each landmark in the normal standard group was from 1.77 to 3.38. A polygonal chart was drawn to visualize the degree of asymmetry. In three patients who had undergone orthognathic surgery, it was checked that the method of facial asymmetry index showed the preoperative facial asymmetry and the postoperative improvement well. Conclusions: The current new facial asymmetry index could efficiently quantify the degree of facial asymmetry from 3D-CT. This method could be used as an evaluation standard for facial asymmetry analysis.

  • This paper presents an Unified Index which can evaluate a performance of a distribution system based on value-based methodology. Reliability cost and voltage sags cost are calculated for each load point using Reliability Sector Customer Damage Function(SCDF). Aging cost is calculated for each load point using Aging SCDF. Power loss cost and operation cost are calculated for the system. By summation of each cost of load point and system, power quality cost can be obtained. Finally, this paper developed an unified index which can show the performance of a distribution system. Presented method has been applied to a real system, the usefulness of the method has been verified.

  • This study proposes a certain measure or investment strategy for decision making associated with seismic retrofitting. This strategy reduces the risk of a large-scale malfunction such as water supply loss under seismic risks. The authors developed a stochastic value index that will be used in the overall evaluation of social benefit, income gain, life cycle costs and failure compensation associated with existing lifeline systems damaged by an earthquake during the remaining service period. Optimal seismic disaster prevention investment of deteriorated lifeline systems is discussed. Finally, the present study provides a performance-based design method for seismic retrofitting strategies of existing lifelines which are carried out using the target probabilities of value loss and structural failure.

  • 흉부방사선 영상의 평가는 시각에 의한 사진평가가 가장 실용적이고 효과적인 방법으로 알려져 있다. 미국 방사선 안전국 규정 평가표(Bureau of Radiological Health, BRH)는 흉부방사선 영상의 해부학적 평가와 물리적 평가를 합하여 평가하는 효율적인 영상 평가방법이다. 본 연구는 여성 351명의 흉부방사선 영상을 체질량지수(Body Mass Index, BMI)와 허리둘레, 관전류량(mAs)과의 관계를 비교하고, 미국 방사선 안전국 규정 평가표를 사용하여 흉부 방사선 영상품질평가를 시행하였다. 대상자의 평균 연령은 $30.17{\pm}4.73$세이고, 허리둘레는 평균 $66.91{\pm}4.67cm$이었다. 체질량지수 값의 평균은 $20.21{\pm}2.23$으로 나타났으며, 전체 대상자의 관전류량 평균값은 $3.04{\pm}0.78$이고, 미국 방사선 안전국 규정 평균값은 $79.83{\pm}8.45$이었다. 허리둘레가 커질수록 관전류량 값이 증가함으로 나타났으며, 체질량지수가 커질수록 mAs값도 증가하였다. 연구대상자의 허리둘레, 관전류량, 미국 방사선 안전국 규정 값은 체질량지수 값이 커지면 허리둘레와 관전류량 평균값이 증가하였고, 미국 방사선 안전국 규정 값은 체질량지수가 높은 그룹이 낮은 그룹에 비하여 상대적으로 낮게 나타났으며, 통계적으로 유의하였다. 흉부검사 시 피검자의 신체두께나 체질량지수에 따라 자동노출제어 장치의 노출제어가 적절히 잘 이루어진 것으로 생각되며, 체질량지수가 증가할수록 신체두께가 커지고 또한 여성의 유방 두께도 증가하여 자동노출제어 장치에 의한 노출량이 변화되어 영상품질에 영향을 미치는 것으로 생각되어진다.

  • Development of index for evaluation of environmental nature and its application for the purpose of construction of industrial complex with environmentally friendly. Industrial complex comes to be recognized as a disgusting zone according to the increasing environment consciousness of residents. And the objection about the exploitation of geographically unwanted land site is increased during development process and it is possible to cause Nimby phenomenon. Therefore, ecology and environment-oriented strategies tends to be adopted for industrial complex development. Furthermore, the maximization of profit mainly directed by enterprises as of today cannot guarantee its future and the efforts of adopting environmental constancy and harmony as a new objective are made progressively. For the development of city and region, in particular such as residence complex, farming and special city, the discussion of environmental consistency, new paradigm with environmentally friendly is briskly under progress, but the relevant discussion for the development of industrial estate is not done so much. Just only few studies are realized from the viewpoint of industrial ecology but its level remains in the understanding of the concepts and presentation of development direction. This study is to prepare for the foundation of the construction of industrial estate with environmentally friendly under the current condition of Korea against coming future environment era and to try to develop of evaluation range and index which are the basis of evaluation of environment. I applied the above evaluation index to the residents of actual industrial estate to understand their consciousness of decreased environment. And I obtained 7 evaluation ranges and 37 evaluation indexes for the relevant residents. Among them, I get the value less than the average in 19 index items. And they represent very sensible reaction about environment pollution including decrease of waste materials. This study has several limits but is meaningful in that the development of evaluation index for environmental nature in industrial complex is done, and that the basic discussion of the plan and design for environmentally friendly industrial estate is made under the above evaluation and that 37 evaluation items are applied to the reality.

  • The international competition in refrigerator markets has continuously required the research for sound quality of a refrigerator to improve the quality of a life. In this paper, A new method for evaluation of the sound quality of a refrigerator is developed based on human sensibility engineering by using ANN(artificial neural network). In this paper, the loudness and the sharpness of the refrigerator's signals was used for the input value in ANN's training process because the loudness and the sharpness has a good correlation between the output of the ANN and the target of the individual evaluation In the training process. Two input factor was used repeatedly in the training process to get more optimum weighting value. And then finally we developed the sound quality index of a refrigerator. The developed sound quality index was confirmed by the 96.5 % of correlation between the output of the ANN and the real evaluation. It will be applied to evaluate the sound quality of a refrigerator in the industry.
