The random amplified polymorphic DNA (RAPD) technique was investigated as a potential tool for the origin identification of olive flounder (Paralichthys olivaceus) and redlip croaker (Pseudosciaena polyactis). Olive flounder specimens were collected from North Korea and several locations of South Korea (Jumunjin, Tongyoung and Geoje). Fishes obtained from Tongyeong and Geoje were cultured products. Redlip croaker specimens were collected from South Korea and China. Consistent and distinct diagnostic bands were easily identified in the RAPD patterns of the olive flounder specimens. Although consistent diagnostic bands rarely appeared in the RAPD pattern of redlip croaker specimens because of their genetic heterogeneity, we were able to find potential diagnostic bands in the average RAPD pattern of each origin.

Objectives: The purpose of this study is to examine the validity, the test-retest reliability and to provide guidelines for the Instrument on Pattern Identifications for Hwa-byung. Methods: Participants are 97 patients with Hwa-byung who were diagnosed by Hwa-Byung Diagnostic Interview Schedule. Participants were tested twice within one week. Results: The test-retest reliability of the Instrument on Pattern Identifications for Hwa-byung was examined for 97 patients and calculated to be 0.3146. The reliability of the Instrument on Pattern Identifications for Hwa-byung was 0.605 with a difference of 5% or more for the first and the second. To confirm the validity of the Instrument on Pattern Identifications for Hwa-byung, we analyzed the relevance between symptoms, Pattern Identifications that belong to the group and other Pattern Identifications that do not belong. Conclusions: It can be diagnosed in the first pattern identification by the Instrument of Pattern Identifications for Hwa-byung when there is a difference of 5% or more in the first and second pattern identification. Based on this result, we derived an Instrument for Pattern Identifications of Hwa-byung that has been further modified through additional studies.

The early detection of brest cancer is clearly a key ingredient for any strategy designed to reduce breast cancer mortality. Microcalcification(MCC) is one of the primary signatures to discriminate between normal and cancerous tissue. The detection and locating procedures can be automated by digital image processing, however, MCCs have various sizes, shapes, and intensity levels in film images, so it is difficult to find accurate locations and sizes. Firstly, we made quantitative analysis for many characteristic features of mammograms that can be used to segment MCCs from normal tissues. Secondly, we developed algorithms proper to segmentation like pattern matching. The performance was evaluated with TP and FP rates.

This paper presents a fault detection and diagnosis methodologies based on weighted symptom model and pattern matching between the coming fault propagation trend and the simulated one. At the first step, backward chaining is used to find the possible cause candidates for the faults. The weighted symptom model(WSM) is used to generate those candidates. The weight is determined from dynamic simulation. Using WSMs, the methodology can generate the cause candidates and rank them according to the probability. Secondly, the fault propagation trends identified from the partial or complete sequence of measurements are compared to the standard fault propagation trends stored a priori. A pattern matching algorithm based on a number of triangular episodes is used to effectively match those trends. The standard trends have been generated using dynamic simulation and stored a priori. The proposed methodology has been illustrated using two case studies and showed satisfactory diagnostic resolution.

The clinical and radiographic findings of lung cancer have been well established many journals. Even if the radiographic findings of lung cancer show a typical pattern, the specific cell type of lung cancer sometimes needs to be determined prior to a pathological diagnosis. For example, the usual finding of a squamous cell carcinoma is similar to other cancer types such as an adenocarcinoma or a small cell carcinoma but with a lower incidence. Therefore, it should not be used to make a diagnosis of the cell type prior to a pathological diagnosis. Many unusual findings of lung cancer, so called atypical pattern have been reported, but atypical findings are widely accepted. The more important thing is not to diagnose a specific cell type of cancer but to differentiate it from other benign conditions such as tuberculosis, fungal infections or organizing pneumonia. This paper presents typical information of the cell type of lung cancer along with the atypical radiographic findings.

Background : According to the rising cases of clinical researches with Traditional Korean Medicine for persistent allergic rhinitis patients, the need for developing and applying Pattern diagnosis instrument has been increasing. Objective : This study was done to investigate and pragmatize the Pattern diagnosis instrument for persistent allergic rhinitis patients launched by KFDA in 2008. Methods : Data was collected by structured survey papers from Korean Medicine doctors participate in the Conference of The Korean Oriental Medical Ophthalmology & Otolaryngology & Dermatology Society in October 2012. We investigated their representative Patterns(변증) of every questions and used the mean results for assuming agreement rates. The importance order of 8 symptom domains for considering Pattern diagnostic steps were also asked and analyzed for inducing importance rates. Finally based on above two results, we developed weight points of each questions by multiplying agrement percents with importance rates. Results : 50 Korean medicine doctors described the informed consent and survey papers. Response agreement rates of each questions of Pattern diagnosis instruments were analyzed and described in Table 2. Comparing the survey results with diagnostic references, matched percent of 肺胃熱 was the 87.9%, 肺氣虛寒 was 62.5%, 肺脾氣虛 was 62.5% and 腎元虧虛 was 50%. Mean importance rates of rhinorrhea was 7.28, otoscope diagnosis 5.12, obstruction 5.04, sneeze 4.82, symptom duration 4.63, other body condition 3.54, tongue diagnosis 3.02, nasal pruritus 2.86, accordingly. Final importance rates of each questions were assumed, and the range of them was from 1.60 to 4.72, which were listed in Table 5. Conclusion : These results might provide the rational backgrounds and practical methods for developing and utilizing methods of Pattern diagnosis questionnaire for perennial allergic rhinitis.

Pulse diagnosis is considered one of the most important diagnostic methods in traditional Korean medicine. Nonetheless, there have been troubles of using pulse diagnosis practically, for the lack of its differential standards and standardized terminology. Rapid pulse belongs to the several traditional pulse types. Rapid pulse was first mentioned in the chinese medical book Haungdineijin that matched it to the fever as well as yang in the human body. Meanwhile, chinese doctors in Ming Ching dynasty of China suggested that rapid pulse meant more of the yin, cold-related reaction than yang and fever. In this study, we organized the past arguments of the rapid pulse and went back tracking what biological activities could be possibly linked to the rapid pulse. Thus, we figured out that the inflammatory mechanism has a close connection with the rapid pulse. The definition of the rapid pulse in Haungdineijin was indicating the acute inflammatory response, while in Ming Ching dynasty, it indicated the chronic inflammation. This is the deficiency-excess pattern of the rapid pulse. Furthermore, we discussed the nonexpression pattern of the rapid pulse which could be happened in case of the heat stroke, etc.

This paper deals with efficient diagnostic for stator winding fault of 3-phase induction motor using a current Park's vector approach. This method firstly transforms 3-phase stator current to vertical axis current and horizontal axis current of Park's Vector, and then obtains the each Park's Vector Pattern and detects stator winding fault by comparing to Park's Vector Pattern of healthy and fault. Experimental results, obtained by using induction motor having inter-turn fault of 2, 10, 20 turn, demonstrate the effectiveness of the proposed technique, for detecting the presence of stator winding fault under 25%, 50%, and 100% of full load condition.

Purpose: Oral lichen planus (OLP) is relatively common mucosal disease in clinical dentistry. OLP is intractable and regarded having malignant potential. Until now, there is some debate on how far OLP can be malignant, and which characteristics can be a risk factor for malignant transformation. Clinician need to know some differences between OLP and lesions similar to OLP to manage properly and suppose prognosis correctly. Therefore, the aim of this study was to divide clinical OLP into two groups and to compare the results of direct immunofluorescence (DIF) between two groups. Methods: This study was conducted on outpatients who visited at the department of Oral Medicine in Chonbuk National University Hospital from January 2007 to November 2015. Patients with DIF result were retrospectively reviewed. The selected patients were classified 'clinical typical of OLP' (CTO) or 'clinical compatible with OLP' (CCW) by modified World Health Organization diagnostic criteria of OLP and oral lichenoid lesion. Results: DIF were classified by deposition intensity or pattern of anti-human antibody and fibrinogen. The classification of fluorescence pattern in each specimen was graded as positive, possibly positive or negative. Conclusions: Both CTO and CCW had positive and possibly positive pattern. Prevalence of positive pattern was 68.8% in CTO and 52.6% in CCW and that of possibly positive pattern was 9.4% in CTO and 5.3% in CCW. Prevalence of negative was 21.8% in CTO and 42.1% in CCW.

Objective : The purpose of this study is to explore the therapeutic potential of Shanghanlun for neuropsychiatric disorders through a comparative review of five neuropsychiatric disorder cases diagnosed with Greater yin disease pattern/syndrome (太陰病). Methods : We collected and compared five neuropsychiatric cases diagnosed and treated with Greater yin disease pattern/syndrome (太陰病) from four korean medicine clinics. Clinical symptoms common to the five cases were analyzed by connecting them with Shanghanlun provision 273 and 279. Results : In all five cases, the improvement of chief complaints and decrease in general anxiety were observed after administration of Gyejigajakyak-tang (桂枝加芍薬湯) and Gyejigadaehwang-tang (圭支加大黃湯). In addition, neuropsychiatric symptoms and physical symptoms that are mentioned in Shanghanlun provision 273 and 279 were confirmed in all five cases. Conclusions : We not only reconfirmed that the core features of Greater yin disease pattern/syndrome(太陰病) proposed in previous studies; zi-tong (自痛), yin-er (因爾), jie-ying (結硬), but also that the physical symptoms associated with fu-man (腹満), tu (吐) and zi-li (自利) were common in the presenting symptoms and past histories of the five patients.
