Purpose : The purpose of this study is to report the comparison of X-ray and Digital Infrared Thermographic Imaging (DITI) of a patient with idiopathic scoliosis. Method: The patient in this case was a 25-year-old female. Her chief complaint was a pain in lumbar, scapular and shoulder regions. We examined her with DITI and X-ray. And then We compared DITI and X-ray. Results: Cobb's angle of thoracic spine was $24.78^{\circ}$ as a primary curve. Cobb's angle of thoracolumbar spine was $17.63^{\circ}$. Temperature on convex side of the thoracic spine was $0.3^{\circ}C$ higher than the other side. Temperature on convex side of cervical spine was $1.4^{\circ}C$ higher than the other side. There was no correlation curvature degree with temperature difference. Conclusion : There was a tendency that the temperature on convex side of the spine is higher than the other side of the spine. DITI is a useful assessment tool when it is used with X-ray as a diagnostic tool of idiopathic scoliosis. Further studies are needed.

Introduction: Ameloblastoma is a benign but locally invasive tumor with a high recurrence rate. The aim of this study was to make an easier diagnosis and treatment planning of ameloblastoma. Materials and Methods: From January 1993 to October 2009, 139 cases from 123 patients, who had been diagnosed with ameloblastoma through radiologic and biopsy in the department of oral and maxillofacial surgery of Kyunpook National University, were selected as the subjects in this study. According to the medical charts, 9 factors (age, gender, location, chief complaints, duration, radiographic findings, size and recurrence) concerned in deciding the treatment method and the relevance between each factor and the treatment methods were examined.(Conservative treatments were marsu-pialization, enucleation, curettage and lateral decortication. Radical treatments included block excision, resection and hemisection) Results: In the patients under the age of 20, 77.14% had conservative treatments, whereas 22.86% underwent radical treatments. In the patients over the age of 20, 44.23% were treated conservatively treatments, and 55.77% underwent radical treatments. For unilocular types, 28.57% had conservative treatments, whereas 71.43% had radical treatments. For the multilocular types, 66.67% underwent conservative treatments, and 33.33% had radical treatments. For the primary cases, 58.68% were treated conservatively and 41.32% had radical treatments. For the recurrent cases, 16.67% and 83.33% underwent conservative and radical treatments, respectively. Conclusion: There was statistical significance in the factors affecting the treatment methods, such as age, radiographic findings and recurrence.

Purpose: This study analyzed the amount of stress and the different effects according to the working times(hours) of a week in two groups: more than 40 hours a week and less than 40 hours a week. Method: The study was conducted from November 1st 2005 to December 15th 2005. The purpose of the study has already been explained in the experiment objectives. 20 copies of evaluation forms were sent by mail to 50 different health sections of participating work sites. A total of 1,000 copies were sent out and 870 were sent back. Within the forms, sent back 120 copies had insufficient data, so 750 copies of evaluation forms were analyzed. Result: Working stress for under 40 hours of working time showed a total of 46.10 points and 47.18 for over 40 hours of working time. For over 40 hours, job demand and occupational climate was high and under 40 hours showed a high rate of job control. For under 40 hours of working time, the factors that caused stress were female, irregular diet habit, age of 30's, nonmanufacturing, and single. For over 40 hours of working time, the factors that causes stress were age of over 40, when the number of employees is 500~999, high rate of fatigue, when the position of the employee is higher then section chief, and when the work amount is high. Conclusion: The stress rate showed significantly higher in over 40 hours of working time. Therefore, adequate working hour distribution and health promotion programs are needed. The factors that cause stress in both under and over 40 hours of working time differed. Therefore, a distinguished program to control work stress for additional working time is needed.

Based on the results from investigation of behaviour of pulverized fly ashes (PFA) at laboratory and field, the way how to reduce the environmental impacts to geotechnical practices Is considered and described. In order to reduce discharged industrial by-products, it should primarily be emphasized that an effort are made as much as possible not to put into homing. Secondarily, an effort must be made to increase amount of utilization to geotechnical engineering practices. In addition, from an environmental point of view, we should challenge to create innovative materials which are eligible for controlling other wastes and remedying contamination m soils by using industrial byproducts which belong to wastes This Is a new concept in which the polluting materials can be eliminated by making use of wastes. Based on the above-stated concept, the previous and possible utilization of PFA is classified into: (1 ) reclamation, embankment or backfill material, (2) light weight geo-material, (8) soil stabilization/improvement, and (4) environmental material. The reason why PFA, in particular, slurry PFA has been used and will possibly be used more widely is due to the fact that PFA has the advantages : (i) low specific gravity leading to a light weight geomaterial, (ii) high pozzolanic activity enhancing strength, especially due to cement addition, and (iii) spherical shape of particles producing isotropy and then pumpability. As well as the concept of reducing geo-environmental impacts, the present text mainly describes the successful results at laboratory and field which have been obtained by the authors. The most important issue hi application of byproducts including PFA for geotechnical practices is to prevent leakage of polluted substances from sedimentary deposits, ground and earth structures. As one of possible techniques far achieving this purpose, a method of washing off the polluted substances by hot water is described.

Eagle's syndrome refers to a symptomatic elongation of the styloid process or calcification of the stylohyoid and stylomandibular ligaments that usually accompanies facial and pharyngeal pain, dysphagia, and foreign-body sensation in the throat. Making an accurate diagnosis is difficult as Eagle's syndrome can be accompanied with referred pain to various areas of head and neck. Treatment options for Eagle's syndrome include non-surgical and surgical methods. The surest and the most effective method for relieving the symptom is surgical removal or reduction of the elongated styloid process. The present study reports two cases of female whom were diagnosed as "Eagle's syndrome" and whose chief complain was foreign-body sensation and pain in the throat on movement. Surgical removal via transoral approach of the elongated styloid process is a safe surgical option with favorable results compared to extraoral approach.

Pleomorphic adenoma is the most common salivary benign tumor, constituting over 60% of parotid gland tumor, 25% of sublingual gland tumor and 50% of minor salivary gland tumor. It is somewhat more frequent in the fourth to sixth decades. The recurrent rate which enforces only a simple enucleation is very high $(20{\sim}45%)$. Histologically, it contains the epithelial cell, the myo-epithelial cell and mesenchymal ingredient, which is various aspect. We analyzed clinicopathologically and immunohistochemically the patients(34 cases) who are diagnosed with pleomorphic adenoma in Dept. of Oral & Maxillofacial Surgery, College of Dentisty, Dankook university since 1998. The results are as follow: 1. The incidence of the tumor was most frequent in age 30 to 50. The ratio of male to female was 1:1.43. 2. The most chief complain was a painless mass(94.1%) and the duration time was more than decade in 18 cases(52.9%). 3. Palate(soft & hard palate) was the most occurred site(64.7%). In major salivary glands, the parotid gland was the most frequent site(17.6%). 4. The tumor size was 2 to 3cm on the average. Most of tumors were with capsule(91.2%). 5. Surgical excision was a main treatment method(20 cases, 58.8%) and 14 cases were excised with a glandectomy, 1 case was treated with a partial maxillectomy. Only 1 case of all cases was recurred. 6. Histopathologically, 9 cases(26.5%) were cellular type, 11 cases(32.4%) were intermediate(classic) type and 14 cases(41.1%) were myxoid type. 7. Immunohistochemically, the specimen of all tumors reacted positively to cytokeratin and vimentin marker.

1.Objects of Research This research is purposed to find methods of treatment on serious diseases, through summarizing etiology, classification and treatment on serious diseases proposed in Sasang constitutional medicine 2.Methods of Research It was researched as bibliologically with Dong-mu's chief medical writings such as ${\ulcorner}$Dongyi Soose Bowon(東醫壽世保元)${\lrcorner}$, ${\ulcorner}$Dongyi Soose Bowon Sasang Chobongyun(東醫壽世保元四象草本卷)${\lrcorner}$ 3.Results and Conclusions 1. The principle of treatment in the previous medicine is to treat each disease by 'Assisting-Good Qi' and 'Removig-Bad Qi'. but The principle of treatment in Sasang Constitutional medicine is to manage incurable disease by helping 'Essential Qi of each constitution(體質正氣)' 2. Incurable disease is classified into a chronic disease by 'Nature(性氣)' and a acute disease by 'Emotion(情慾)'. Both diseases became serious through 'Noi-Ok(牢獄)' and 'Wi-Gyoung(危傾)'. A chronic disease is much in the middle years of life and become senile disease. A acute disease is much in the young years of life and make patients die young. 3. prognoses of incurable disease are different from degree of Inherent vitality(命脈實數) and term of disease. The case in which Inherent vitality is exhausted is thought that is unable to treat. 4. The prevention of incurable disease Is more important the treatment of one in Sasang Constitutional Medicine. but if incurable disease is caught, Medicine(醫藥) and management(調養) must be used together for treatment of incurable disease. Medicine is more important in the level of 'Noi-Ok(牢獄)' and management is more important in the level of 'Wi-Gyoung(危傾)'. 5. Therefore, incurable disease should be treated by method that 'Essential Qi of each constitution(體質正氣)' is recovered and declination is removed through 'controlling mind(治心) and correcting Qi(正氣), so then the state of 'Golden mean(中庸)'　is reached.

The purpose of this study was to explore what chiefs of tong/ri' experiences in suicide prevention activities are and what their changes are. The study participants are three chiefs of tong/ri who have participated in suicide prevention activities for more than two years in the community. In order to gain a deeper understanding of their respective experiences, used a qualitative method of narrative study. Chiefs of tong/ri' experiences experience in participating in suicide prevention activities consisted of start, experience, change and growth. The meaning is as follows. They did a "light start" with the idea that they could do it easily in their original activities. "Escape from the burden" of learning and maintaining each of own ways in the difficult problem of suicide prevention, "Responsibility as a chief" was the driving force behind suicide prevention activities. They were able to find "change of their own" because of the activity naturally.

The purpose of this study is to investigate the versatility of indecisive clients which is one of the seven key factors to identify indecisiveness by analyzing Holland's 3-letter code with consistency and calculus. By implementing the method of Occupational Card Sort, all six clients showed low consistency in the three codes as well as between the first code and their thesis statements. They also showed mismatching of three codes evaluated with the thesis statements. From observing calculus from the hexagonal model, all six Holland codes showed balanced development and similarity of calculus between the codes in adjacent. The result of the study finds that various interests may cause indecision in one's career decision-making.
