Purpose: This study examined the risk factors of a delayed diagnosis of acute appendicitis in children undergoing an appendectomy. Methods: This retrospective study involved children aged below 18 years, who underwent an appendectomy. After dividing them into a delayed diagnosis group and nondelayed diagnosis group according to the time interval between the initial hospital visit and final diagnosis, the risk factors of delayed diagnosis were identified using logistic regression analysis. Results: Among 712 patients, 105 patients (14.7%) were classified in the delayed diagnosis group; 92 patients (12.9%) were diagnosed using ultrasonography (US), and both US and computed tomography were performed in 38 patients (5.3%). More patients in the delayed diagnosis group underwent US (P=0.03). Spring season and prior local clinic visit were significantly associated with a delayed diagnosis. Fever and diarrhea were more common in the delayed diagnosis group (fever: odds ratio [OR], 1.37; 95% confidence interval [CI], 1.05-1.81; diarrhea: OR, 1.94; 95% CI, 1.08-3.46; P<0.05). These patients showed symptoms for a longer duration (OR, 2.59; 95% CI, 1.78-3.78; P<0.05), and the admission course (OR, 1.26; 95% CI, 1.11-1.44; P<0.05) and C-reactive protein (CRP) levels (OR, 1.47; 95% CI, 1.19-1.82; P<0.05) were associated with the delayed diagnosis. Conclusion: To decrease the rate of delayed diagnoses of acute appendicitis, symptoms such as fever and diarrhea, seasonal variations, admission course, and CRP levels should be considered and children with a longer duration of symptoms should be closely monitored.

Purpose: The actual nursing processes have been performed by individual nurses' judgment without any supporting programs in Korea. It is not easy for novice nurses to make accurate diagnoses and provide proper nursing interventions to patients. Therefore, we propose a computerized program for nursing diagnosis and intervention linked to medical diagnosis. Method: For the program, we have linked standardized nursing diagnosis and intervention classifications with medical diagnosis. It is premised that the program is connected to order communication system(OCS) in hospitals. Result: We provide a nursing information system with standardized database for nursing diagnosis and interventions so that nurses can make more accurate diagnosis and perform more adequate interventions. Conclusion: It is expected that the program will help the nurses perform their nursing processes more efficiently. And we expect the system can be used in many hospitals efficiently in the future after pilot operations are completed in some hospitals.

For having good therapeutic value, putting the ideal of diagnosis and treatment based on overall analysis of symptoms and signs[辨證施治] into practice is very important, so the Eastern Medicine's peculiar diagnosis without interference by the western medical diagnosis is very important. The peculiar method of Eastern Medicine's diagnosis is four methods of diagnosis(四診法), a joint term for inspection, auscultation and olfaction, interrogation, pulse feeling and palpation. In the process of interrogation[問診], from analyzing the perspiration phase, doctor can get various physical information. Especially perspiration from particular region can be a clue for founding focus or cause of disease. This thesis divide the phase of perspiration into eight bodily region, perspiration from all body, head, face, back, chest and armpit, stomach, pubic region and lower part, hands and feet, and inquire the possible causes and principles of these perspirations. In conclusion, the regional perspiration can be a clue point out the origin of fever and condition of Gi(氣) flow. Perspiration from head, back, chest and armpit, hands and feet means that certain fever cannot extend to the outside of body, and at the same time, means the Gi(氣) flow of outside is being intercepted. So the perspirations from that region become an object of medical treatment.

In traditional Chinese medical (TCM) science, tongue images can be observed for medical diagnosis; however, the tongue diagnosis of TCM is influenced by the subjective factors of doctors, and the diagnosis results vary from person to person. Quantitative TCM tongue diagnosis can improve the accuracy of diagnosis and increase the application value. In this paper, digital image processing and pattern recognition technologies are employed on mobile device to classify tongue images collected in different health states. First, through grayscale integral projection processing, the trough is found to localize the tongue body. Then the tongue body image is transferred from RGB color space to HSV color space, and the average H and S values are considered as the color features. Finally, the diagnosis results are obtained according to the relationship between the color characteristics and physical symptoms.

Clinicians should looking for techniques that helps to early diagnosis of cancer, because early cancer detection is critical to increase survival and cost effectiveness of treatment, and as a result decrease mortality rate. Medical images are the most important tools to provide assistance. However, medical images have some limitations for optimal detection of some neoplasias, originating either from the imaging techniques themselves, or from human visual or intellectual capacity. Image processing techniques are allowing earlier detection of abnormalities and treatment monitoring. Because the time is a very important factor in cancer treatment, especially in cancers such as the lung and breast, imaging techniques are used to accelerate diagnosis more than with other cancers. In this paper, we outline experience in use of image processing techniques for lung and breast cancer diagnosis. Looking at the experience gained will help specialists to choose the appropriate technique for optimization of diagnosis through medical imaging.

The goal of this study is to develop knowledge representation method for the construction and evaluation of ontology for diagnosis in oriental medicine. To develop the expert system for decision making on diagnosis and treatment, the systematic and structural knowledge which can be processible in EMR(Electronic Medical Record) must be precedent, and the Computational Process which control the system as well. This study set up an ontology as a trial model to represent the oriental medical knowledge into the machine processible one. Protege 2.1 has been used to build the ontology, and the serialization format of our ontology is the XML document based on OWL. The components of oriental medical diagnosis was arranged with the combination of symptoms which belong to the certain symptom patterns. Then natural language which expresses the oriental medical diagnosis components were converted into the logical sentence, and individual characteristic symptoms into each values of specific properties. In addition to the study, the diagnosis software for oriental medicine was developed and it used the ontology which we developed. Sequently, we tested the software to confirm the appropriateness of ontology. The result of the test shows that diagnostic questions are automatically formulated according to the diagnosis components of this ontology and that as such diagnostic results are induced. Therefore, the ontology system in this study will be efficient to develop the diagnosis program and useful as a tool for doctors to make decision. But, it is not recommendable to apply the system to the clinical environment until the clear diagnosis standards are introduced, and the more reliable diagnosis program can be developed based on the more appropriate ontology mentioned above.

Objectives : This paper studies the pulse diagnosis as found in Youksimanpil, which is a series of medical charts containing 150 diagnosis records of Yi Suki, a doctor who was active in Joseon during the 17-18th centuries. Through this effort, the paper aims to shed light on how pulse was utilized in the Korean medicine, and in process tries to reveal the essence of Korean medicine's treatment method. Methods : 60 charts where pulse method was used are selected in Youksimanpil and a table is created with them. Figures are drawn to explain four steps of pulse-sensing from the simple method to highly advanced method. Charts are presented with the corresponding original texts and their translations. With these efforts, the paper attempts to reveal the broad understanding of the doctor of Joseon period who consistently kept to the most basic principle of pulse diagnosis. Results : The efficiency of pulse diagnosis depends on the unity and simplicity in diagnosis and prescription. There were continued efforts between the doctors in Joseon to collect and compare the experiences they gained from clinical practices in order to organize their findings and form a system. These are: (1) individual pulse, (2) patternized pulse, (3) balance between left and right pulses, (4) balance between pulse and body, and (5) the doctor's extemporaneous diagnosis. In that efforts, they protect the principle of holistic diagnosis, which is one of Korean medicine's core principles. Conclusions : Thanks to the existence of medical charts that presents in detail how the texts of Donguibogam were applied in real clinical practices, today we can see Korean medicine's highly advanced synergy between textual knowledge and clinical experiences as recorded in the form of charts.

Objective: We estimated the total medical costs incurred during the 5 years following a cancer diagnosis and annual medical use status for the six most prevalent cancers in Korea. Methods: From January 1 to December 31, 2006, new patients registered with the six most prevalent cancers (stomach, liver, lung, breast, colon, and thyroid) were randomly selected from the Korea Central Cancer Registry, with 30% of patients being drawn from each cancer group. For the selected patients, cost data were generated using National Health Insurance claims data from the time of cancer diagnosis in 2006 to December 31, 2010. The total number of patients selected was 28,509. Five-year total medical costs by tumor site and Surveillance, Epidemiology, and End Results (SEER) stage at the time of diagnosis, and annual total medical costs from diagnosis, were estimated. All costs were calculated as per-patient net costs. Results: Mean 5-year net costs per patient varied widely, from $5,647 for thyroid cancer to $20,217 for lung cancer. Advanced stage at diagnosis was associated with a 1.8-2.5-fold higher total cost, and the total medical cost was highest during the first year following diagnosis and decreased by the third or fourth year. Conclusions: The costs of cancer care were substantial and varied by tumor site, annual phase, and stage at diagnosis. This indicates the need for increased prevention, earlier diagnosis, and new therapies that may assist in reducing medical costs.
