Currently, Korea is an aging society and is expected to become a super-aged society in about four years. X-ray devices are widely used for early diagnosis in hospitals, and many X-ray technologies are being developed. The development of X-ray device technology is important, but it is also important to increase the reliability of the device through accurate data management. Sensor nodes such as temperature, voltage, and current of the diagnosis device may malfunction or transmit inaccurate data due to various causes such as failure or power outage. Therefore, in this study, the temperature, tube voltage, and tube current data related to each sensor and detection circuit of the diagnostic X-ray imaging device were measured and analyzed. Based on QC data, device failure prediction and diagnosis algorithms were designed and performed. The fault diagnosis algorithm can configure a simulator capable of setting user parameter values, displaying sensor output graphs, and displaying signs of sensor abnormalities, and can check the detection results when each sensor is operating normally and when the sensor is abnormal. It is judged that efficient device management and diagnosis is possible because it monitors abnormal data values (temperature, voltage, current) in real time and automatically diagnoses failures by feeding back the abnormal values detected at each stage. Although this algorithm cannot predict all failures related to temperature, voltage, and current of diagnostic X-ray imaging devices, it can detect temperature rise, bouncing values, device physical limits, input/output values, and radiation-related anomalies. exposure. If a value exceeding the maximum variation value of each data occurs, it is judged that it will be possible to check and respond in preparation for device failure. If a device's sensor fails, unexpected accidents may occur, increasing costs and risks, and regular maintenance cannot cope with all errors or failures. Therefore, since real-time maintenance through continuous data monitoring is possible, reliability improvement, maintenance cost reduction, and efficient management of equipment are expected to be possible.

Male breast cancer is a very rare disease with an incidence of about 0.5-1% comparing with the one of female breast cancer but relatively little is known about its cause. Treatment strategies for breast cancer in males are derived from studies performed among females. The probable reasons behind the frequent, late diagnoses presented at stages III or IV might be the lack of awareness. The rarity of the disease precludes large prospective randomized clinical trials. This study reviews male breast cancer and its risk factors, recommendations for diagnosis and the management of patients with male breast cancer.

Prostate cancer, with a lifetime prevalence of one in six men, is the second cause of malignancy-related death and the most prevalent cancer in men in many countries. Nowadays, prostate cancer diagnosis is often based on the use of biomarkers, especially prostate-specific antigen (PSA) which can result in enhanced detection at earlier stage and decreasing in the number of metastatic patients. However, because of the low specificity of PSA, unnecessary biopsies and mistaken diagnoses frequently occur. Prostate cancer has various features so prognosis following diagnosis is greatly variable. There is a requirement for new prognostic biomarkers, particularly to differentiate between inactive and aggressive forms of disease, to improve clinical management of prostate cancer. Research continues into finding additional markers that may allow this goal to be attained. We here selected a group of candidate biomarkers including PSA, PSA velocity, percentage free PSA, $TGF{\beta}1$, AMACR, chromogranin A, IL-6, IGFBPs, PSCA, biomarkers related to cell cycle regulation, apoptosis, PTEN, androgen receptor, cellular adhesion and angiogenesis, and also prognostic biomarkers with Genomic tests for discussion. This provides an outline of biomarkers that are presently of prognostic interest in prostate cancer investigation.

This study was to investigate diadochokinetic (DDK) rate, regularity and mean flow rate of articulation valves in dysarthria. DDK rate, mean airflow rate (MFR) and regularity of DDK syllable repetitions of vocal function /ihi/, tongue function /ta/, velopharyngeal function /bm/, and labial function /pa/ in 24 normal and dysarthric speakers were measured. Aerophone Ⅱ and Motor Speech Profile were used for data recording and analysis. The results of the findings were as follows: First, there were significant differences between the dysarthria and the normal group in DDK rate. DDK rates in ataxic dysarthria were the lowest and spastic, flaccid, and hypokinetic dysarthria followed in sequence. Second, there was a significant difference between the dysarthria and the normal group in DDK regularity. Third, there was a significant difference between dysarthria groups and normal group in DDK MFR. Finally, there was a significant difference between the 4 groups of dysarthria and the normal group in DDK air flow tracking. The results of this study can be guidelines for normal DDK rate, regularity and flow rate in dysarthria groups. In addition, their differential diagnoses and descriptions are important to make a decision on medical and behavioral management of the individuals with disorders according to DDK characteristics.

Fine needle aspiration biopsy cytology is a widely recognized and useful technique which can provide diagnosis in lesions of the head and neck, enabling appropriate management plans for individual patient to be made. Fifty one fine needle aspirates from salivary gland masses were examined. Four aspirates (8%) were inadequate for examination. Of the remaning 47 samples, 42 cases (82%) were benign lesions which consist of 30 pleomorphic adenoma(58%), 7 inflammatory lesion (14%), 4 Warthin's tumor(8%) and 1 benign lesion(2%). Two cases(4%) were atypical lesions. Three cases(6%) were malignant lesions consisting of 2 adenoid cystic carcinomas(4%) and 1 mucoepidermoid carcinoma (2%). The cytologic diagnoses were compared with the subsequent histologic diagnosis of surgical resected specimen in 24 cases. 19 cases of 21 aspirates from benign tumors were correctly diagnosed by fine needle aspiration cytology, with a specificity of 90%. All 3 aspirates from the 3 patients with malignant tumor were correctly diagnosed by fine needle aspiration cytology, with a sensitivity at 100%. Overall acurracy was 88%. Diagnostic error was encountered in adenoid cystic carcinoma, mucoepidermoid carcinoma and Warthin's tumor Correct histologic diagnosis was made in 86% of benign tumors(84% for pleomorphic adenoma and 100% for Warthin's tumor) and in 100% of malignant tumors.
