  • In this paper, we synthesized vowel /ae/ with voice synthesis program of Dr. Speech Science, and we also synthesized pathologic vowel /ae/ by some parameters such as high frequency gain (HFG), low frequency gain(LFG), pitch flutter(PF) which represents jitter value and flutter of amplitude(FA) which represents shimmer value, and grade ranked as mild, moderate and severe respectively. And then we analysed all pathologic voice by analysis program of Dr. Speech Science. We expect that this synthesized pathologic voices are useful for understanding the parameter such as noise, jitter and shimmer and feedback effect to patient with voice disorder.

  • The symptoms that have same pathologic pattern written in the chapter of Soyangin's general pathology of the book 'Dongyi Soose Bowon' can give us a key to the Dr.Lee Je-Ma's point of view about the constitutional pathophysiology. As the result, Dr. Lee called the person who has yang-hyperactivity/yin-hypoactivity as So-Yang-In. And the Soyangin has two basic pathologic pathway ; excess of Yang-hyperactivity/excess of Yin-hypoactivity. Each pathologic pathway has variatons though, the pathologic pattern results in above two type. Excess Yin-hypoactivity has three variations of pathologic pattern. 1. smaller excess of Yin-hypoactivity with the normal range of Yang-hyperactivity 2. larger excess Yin-hypoactivity with the excitation of Yang-hyperactivity by the extrinsic factor 3. smaller excess Yin-hypoactivity with the loss of Yang-hyperactivity. And excess Yang-hyperactivity also has three variations. In my point of view, CVA, Hematemesis, Vommiting, Abdominal Pain, Gastric Dyscomfort has No.3 type and Asthmatic condition, Dysentery, Edema has No.1 type.

  • In this study, the most stable portion was identified using 5% moving window during /a/ sustained phonation in normal and pathologic voice signals and the perturbation values were compared between normal and pathologic voices at the mid-point and at the most stable portion using moving window, respectively. The results revealed that some severe pathologic voice signals can be eligible for perturbation analysis by identifying the most stable portion with Err less than 10. In addition, the perturbation acoustic parameters did not differentiate the pathologic voice signals from the normal voice signals when the mid-point was selected to measure the perturbation analysis(p>0.05). However, significantly higher %shimmer and lower SNR values were observed in pathologic voices (p<0.05) when the most stable portion was selected by moving window. In conclusion, moving window could identify the most stable portion objectively which can allow toget the minimum perturbation values (%jitter, %shimmer) and maximum SNR values. Thus, moving window technique can be applicable for more reliable and accurate perturbation acoustic analysis.

  • Pathologic fractures of the mandible can occur for many reasons including osteoradionecrosis, osteomyelitis, malignancy and cyst. Pathologic fractures are difficult to treat because management is needed not only for the fractures of the mandible but also the underlying disease the is weakening the bone. Additionally, the diseased mandible in the pathologic fracture frequently has abnormal bone healing capacity. We experienced three cases of pathologic fractures of the mandible resulting from cyst, malignancy and osteomyelitis. The treatment of these cases was complicated and time-consuming. Therefore, we present our three cases and discuss the management of pathologic fractures of the mandible.

  • Background: To investigate the relationship between pathologic tumor response to concurrent chemoradiotherapy and variation of serum VEGF in patients with esophageal cancer. Materials and Methods: Forty six patients with esophageal cancer who were treated with concurrent chemo-radiotherapy were enrolled. Endoscopic and pathologic examination was conducted before and four weeks afterwards. Serum level of VEGF was documented before, four weeks later and after chemo-radiotherapy. The relationship between pathologic response and the variation of serum level of VEGF and its influence on the prognosis were investigated. Results: Serum level of VEGF decreased remarkably during and after chemo-radiotherapy in patients whose pathologic response was severe (F=5.393, 4.587, P(0.05). There were no statistical differences of serum VEGF level before, during and after chemo-radiotherapy for patients whose pathologic response was moderate or mild. There were 18 (85.7%), 7 (53.8%) and 6 patients (50.0%) whose serum VEGF level dropped in the severe, moderate and mild group, respectively, with significant differences among these groups (p=0.046). Two year survival rates of patients with severe, moderate and mild pathologic response were 61.9%, 53.8% and 33.3% respectively, and no statistically difference between severe and mild group regarding OS (p=0.245) was tested. Conclusions: Tumor pathologic response during chemo-radiotherapy and the changes of serum VEGF lever could predict curative effects of chemo-radiotherapy in patients with esophageal cancer.

  • Background: The aim of this study is to evaluate prognostic factors for survival in pathologic stage IIIA/N2 non-small-cell lung cancer (NSCLC), to identify the prognostic significance of the metastatic patterns of mediastinal lymph nodes (MLNs) relating to survival and to recurrence and metastasis. Methods: A total of 129 patients who underwent radical resection for pathologic stage IIIA-N2 NSCLC from July 1998 to April 2011 were retrospectively reviewed. The end points of this study were rates of loco-regional recurrence and distant metastasis, and survival. Results: The overall 5-year survival rate was 47.4%. A univariate analysis showed that age, pathologic T stage, and adjuvant chemotherapy were significant prognostic factors, while in multivariate analysis, pathologic T stage and adjuvant chemotherapy were significant prognostic factors. The metastasis rate was higher in patients with multi-station N2 involvement and with more than 3 positive MLNs. Further, non-regional MLN metastasis was associated with a higher loco-regional recurrence rate. Conclusion: Pathologic T stage and adjuvant chemotherapy were independent prognostic factors for long-term survival in pathologic stage IIIA/N2 NSCLC. The recurrence and the metastasis rate were affected by the metastatic patterns of MLNs. These results may be helpful for planning postoperative therapeutic strategies and predicting outcomes.

  • Objectives: To develop and investigate the reliability of the pathologic aging scale based on korean medical theory and korean medical pattern identification for dementia. Methods: We searched the textbook of korean neurophychiatry and Donguibogam and selected items through professional consensus. We compared between dementia(n=40) and normal elderly(n=38) and tested the reliability of two scales. Results: After professional consensus, we drafted the Korean Medical Pathologic Aging Scale(12 items, Likert 3 scale) and Korean Medical Pattern Identification for Dementia(4 patterns, 28 items, Likert 5 scale). On Korean Medical Pathologic Aging Scale, There is no significant difference between two groups. We had good internal consistency(Cronbach's alpha = 0.6) and test-retest reliability(r=0.631) but low inter-rater reliability(r=0.430). On Korean Medical Pattern Identification for Dementia, dementia patients diagnosed with Qi deficiency are significantly more than those in normal group. We had fairly good internal consistency(Cronbach's alpha = 0.574) and excellent test-retest(kappa= .800) and inter-rater reliability(kappa = .733). Conclusions: Korean Medical Pattern Identification for Dementia is appropriate for diagnosing korean medical pattern. But Korean Medical Pathologic Aging Scale isn't appropriate to discriminate dementia from normal elderly because of many subjective items. Therefore objective measurement of sensory dysfunction would be needed to measure pathologic aging based on korean medical theory.

  • Deciduous teeth can be extracted for two reasons, one due to the physiologic resorption and the other by the inflammation at the apex after traumatic injury. Physiologic resorption may be different from pathologic resorption in timing and mechanism. Therefore we resumed the different features of physiologic and pathologic resorption root surfaces. Many previous studies showed micromorphology of resorbed surface of roots of deciduous teeth. But, few studies compared physiological and pathological root resorption surfaces. In this study, we carefully observed microscopic morphologies of those two different root surfaces by scanning electron microscope and histologic features by light microscope. The resultant differences between physiologic and pathologic resorption surfaces of deciduous teeth were as follows: 1. The morphology of pathologic resorption lacunae due to inflammation varied in size and shape with irregular boundaries compared with the physiologic areas from scanning electron microscope observations. 2. From light microscope observations, several large resorption fossae containing numerous resorption lacunae were found, whereas the resorption lacunae were irregular in shape with pathologic resorption surface. 3. Numerous multinucleated giant cells were closely attached to the physiologic resorption lacunae, whereas several kinds of mesenchymal cells with numerous inflammatory cells were found in the areas adjacent to the pathologic resorption surface. 4. Light microscope findings showed that compensating cementum formation took place along some of the areas of inflammatory dentinal resorption. In conclusion, several morphological differences were present between physiologic and pathologic root resorption surfaces of human deciduous teeth. The future studies should include cytochemistry to clarify the cellular roles in resorption process observations of pulpal surfaces of coronal and radicular dentin to and the changes that occur in each phase of human deciduous tooth resorption.

  • Objectives: Chiljeong means the basic emotions containing joy, anger, anxiety, depression, fear and fright in Korean traditional medicine. Chiljeong was considered as a cause diseases or syndrome. The pathology of Chiljeong described the action of the gi and the principle of eumyangohaeng. When we treat the psychiatric symptoms in Korean traditional medicine, we need to understand the pathologic mechanism of Chiljeong. Methods: We extract the sentences regarding Chiljeong, Oji, Chilgi and Gugi along with the related words in Donguibogam. We analyze the selected sentences and classify the pathologic mechanism according to the general and seven emotions. Results: We found that several parts were related to Chiljeong, except the Sinmun, including the psychiatric symptoms in Donguibogam. Conclusions: The most frequently mentioned affected areas of basic Jangbu are Sim and Gan. The pathologic mechanism of general emotion was categorized by sentences into 4 groups, Giul, Dameum, Hwa and Heo.
