The maintenance of tunnels is often neglected since tunnels has tendency to become stable with time. The determination of safety of tunnels is a complicated problem. So the role of experienced engineer in the maintenance is very important and development of an expert system which can perform as these engineers has been needed. In this study, an expert system which can determine the safety of tunnels is developed. The developed knowledge base contains the maintenance procedure which is used in KlSTEC(Korea Infrastructure Safety & Technology Corporation). Field test, laboratory test and nondestructive test methods are considered in this knowledge base. Criteria for each item and integrated diagnosis criteria are implemented in the expert system based on literatures and reports. The expert system includes basic inspection. detail inspection and precision inspection. For precision inspection. it has the capacity to exchange the result from numerical analysis by a commercial program FLAC. To verify the expert system. the proposed procedure was compared with an existing tunnel diagnosis report.

우리나라는 1994년에 발생한 성수대교 붕괴사고를 계기로 ｢시설물의 안전 및 유지관리에 관한 특별법｣이 제정되면서 시설물의 안전점검 및 유지관리 분야에 많은 노력을 기울이고 있다. 이러한 시설물 중 건축물 다음으로 가장 많은 비중을 차지하는 교량은 현재 총33,165개소가 공용 중이며, 2, 3종 교량의 경우 28,150개소로 전체 비중의 약 85%를 차지하고 있다. 하지만 교량의 대부분을 차지하고 있는 2, 3종 교량은 상대적으로 중요도가 높은 1종 교량에 비해 점검진단 등에 관한 유지관리 현황이 미흡한 실정이다. 이러한 이유는 교량의 점검진단 수행 시 점검진단 수행자의 주관적인 판단 및 기록, 체계적으로 수립되지 못한 점검진단 보고서 양식 등에서 나타난다. 따라서 본 연구에서는 기존 점검진단 보고서의 문제점을 수정 및 보완하여 체계적이고 지속적으로 활용 가능한 점검진단 보고서의 개선(안)을 도출하고자 한다.

Objectives For the excellent differentiation of syndromes, we study on the individual characteristic factor by the inspection of body shape. Methods To the subject of diagnosis special books and diagnostics textbook of korean medicine, we arrange the individual characteristic factor by the four methods of diagnosis. Results The individual characteristic factor analyzed by the inspection of the body shape in the "Huangdineijing 黃帝內經" and "Donguisusebowon 東醫壽世保元" was observed stereotyped. The inspection of the body shape means to diagnose the patient by examining the individual physical conditions of the patient. The body depends on visceral essence to nourish, while the functions of the viscera and the conditions of visceral essence may be reflected by the body. The inspection of individual physical strength and weakness may enable one to know the functions of the viscera and the conditions of ki(氣) and blood. And also the inspection of local regions is used to closely examine some regional areas to obtain necessary clinical data on the individual characteristic factor. Conclusion As the results, the individual characteristic factor by the inspection of body shape is very important item of the four methods of diagnosis(四診) and the differentiation of syndromes(辨證). And therefore the process on four methods of diagnosis and differentiation of syndromesis is necessary to divide the signs of individual characteristic factor and the signs of disease.

Brucella (B.) canis is mainly transmitted by direct or indirect contact with aborted fetuses and placenta. It's also known to be able to infect human, which likely results in providing veterinarians and companion animal owners for infectious risk. To develop diagnostic ELISA, we cloned and expressed rp1L gene of B. canis, which encodes the ribosomal protein L7/L12. Using this purified recombinant protein, indirect-ELISA (iELISA) was evaluated using 78 positive and 44 negative sera. The sensitivity and the specificity of iELISA were 94% and 89%, respectively. The results indicated that indirect-ELISA using recombinant ribosomal protein L7/L12 may be useful for diagnosis of canine brucellosis.

The selection of the correct examination variables for diagnosing heart disease provides many benefits, including faster diagnosis and lower cost of examination. The selection of inspection variables can be performed by referring to the data of previous examination results so that future investigations can be carried out by referring to these selected variables. This paper proposes a model for selecting examination variables using an Artificial Bee Swarm Optimization method by considering the variables of accuracy and cost of inspection. The proposed feature selection model was evaluated using the performance parameters of accuracy, area under curve (AUC), number of variables, and inspection cost. The test results show that the proposed model can produce 24 examination variables and provide 95.16% accuracy and 97.61% AUC. These results indicate a significant decrease in the number of inspection variables and inspection costs while maintaining performance in the excellent category.

The purposes of this study were to evaluate the results of the hospital self inspection with the medical insurance and to offer basic materials to the medical insurance inspection and the education of medical insurance. The study was undertaken with 4,730 cases among the total 13,810 medical insurance in patients from Jan. 1990 to Dec. 1990 at one university hospital in Pusan. The major contents of the inspection were the omission of diagnosis and medical fee, curtailment, application mistake, the rates of inclusion, subtraction and total accumulation. The data were collected using patients charts and bills. The results of the paper analysis were as follows. 1. From the pre-discharge hospital self inspection, major omission were treatment and material fee but medication fee were moderately high and high curtailment was operation fee. 2. Decreasing order of operation fee adjustment were digestive(22.4%) muscular(22%) and neuro system operation(21.4%). Majority of the medication fee adjustments were injection form of medication(95.7%). 50% of the treatment fee adjustments were composed of injection fee(27.9%) and dressing or post-operative dressing fee(22.3%). 74.7% of material costs were composed of oxygen(30.6%), blood and the blood composed materials(44.1%). 3. Pre-discharge inspection showed 6% adjustment rate, 4.3% addition and 2.1% curtailment rate. Most of the adjustment were omission(66.1%). 4. Omission were divided by event omission(92.6%)and application mistake(7.4%). The decreasing order of omission fee were operation(21.84%), treatment(18.71 %) diagnosis(18.68%), medication (14.53%) and material costs(10.84%). So operation and treatment part were the major part of the total omission fee(40.55%). 5. The average omission of diagnosis were 1,800 per month.

A new live-line insulator tester was developed to detect faulty insulators in 154kV power transmission lines. This paper is the second part of the two-part paper and deals with its inspection algorithm development. Unlike normal condition with low pollution and low humidity, the inspection data measured in the field under high pollution or high humidity showed that the voltage distribution of an insulator string has offsets in comparison with those of others and its insulation resistances are greatly decreased, which leads to wrong results of the existing inspection algorithms under such conditions. To solve this problem, we propose new diagnosis algorithms that can exactly detect faulty insulators from measured data regardless of environmental conditions. Its effectiveness was validated by live-line field tests in actual power lines.
