In recent years, the case to install small water treatment facility to every local area has increased. A key issue in the successful implementation of the control systems for the water treatment plants is the choice of control architecture. Within the framework of distributed control system(DCS), this paper presents a new development of intelligent control module and its novel application to open control architecture for water treatment plants. This control system so called NCS(Network Based Control System) with standard networks system with LonTalks protocol of ANSI/EIA 709.1, regulatory control function and information dispatch function has suitable functionality to operate these distributed water treatment facility effectively. This paper describes the case where NCS is applied for the filters system in water treatment facility of Heong Sung area.

Pulmonary tuberculosis is still one of unsolved problems in Korea due to increased number of far-advanced and drug-resistant patients, who have poor pulmonary function. We have analyzed 1332 operated Gases during the period of 1958-1981. Annual incidence of the disease decreased from 110 [1960] to 21 [1980]. The ratio between male and female was 7:3 and the age of peak incidence was in the 3rd and 4th decades. Recently, patients below the age of 20 years were slightly decreased, but above 50 years were slightly increased. The patients consisted of far-advanced case in 60% and moderately-advanced in 39% in 1980, as compared with 40% and 59% correspondingly in 1965. Preoperative sputum positively decreased from 91% [1958-1963] to 43.8% [ 1974-1981 ]. Medically treated patients for more than 3 years increased from 16% [1958-1963] to 51% [1974-1981]. From the view of surgical indication, totally destroyed hung increased from 27% [1958-1963] to 4396 [1974-1981 ]. Therefore, pneumonectomy occupied 53.8% of total surgical management recently. Mode of surgical treatment showed that thoracoplasty [33%], resection [57%] in 1958-1963 and thoracoplasty [2%], resection [98%] in 1974-1981. As Semb`s thoracoplasty was the first choice of treatment until 1960, thereafter resection became the choice. Postoperative mortality increased from 1.6-2.096 to 396 recently as well as morbidity. It was mainly due to increased number of poor pulmonary function and postoperative spread of disease. On the basis of our experience, far-advanced and drug-resistant patients increased in number recently, whose pulmonary function was poor. So postoperative mortality and morbidity increased. Proper surgical intervention should be considered before the appearance of resistance for all chemotherapeutic drugs.

Objectives : The purpose of our study was to evaluate penicillin as a still drug of choice for severe endodontic infection, by analyzing the antimicrobial susceptibilities from endodontic infections with swelling to figure out appropriate antibiotics as empirical treatment. Materials and methods : This study involved 18 patients who attended for emergency treatment because of facial or periapical swelling associated with root canal infections. Identification and antimicrobial susceptibility test of each pathogen were performed by Vitek2 Systems (bioM$\acute{e}$rieux, Marcy l'Etoile, France). Results : The most frequent bacteria was Streptococcus spp.(77%), and the resistance against penicillin was 35% in overall patients, followed by clindamycin and erythromycin (17%), which was much higher than previous studies. Conclusions : In our study, the higher resistance made penicillin alone not to be chosen as the first antibiotic drug for severe endodontic infections. Combinations with other drug, penicillin with wider spectrum of activity, or changing to other antibiotics was considered while remembering the increased risk of resistant microorganism.

Staphylococcal pneumonia caused by staphylococcus aureus can be characterized by its severity and rapid progress as a bacterial infection. The disease shows a high mortality in younger patients, especially in infants unless early and appropriate treatment is carried out. Treatment can be made of medical method alone but in cases of surgical interventions are needed, immediate surgical methods such as closed or open drainage of pleural fluid, lobectomy and decortication should be followed with combination of medical therapy. The choice of antibiotic should be made by proper antibiotic sensitivities tests. For a methicillin sensitive S. areus(MSSA), the penicillase resistant penicillin would be the first choice and for a methicillin resistant S. aureus (MRSA), the glycopeptides such as vancomycin would be the first one. Other drugs can also be used if the bacterial agents show any sensitivities to these drugs. Commonly, the chest roentgenographic findings reveal infiltrations, empyema, pneumothorax, pleural effusion, atelectasis or pneumatoceles in staphylococcal pneumonia and this fact easily can lead the physicians to its diagnosis as soon as possible. We experienced 5 cases of staphylococcal pneumonia in infants, proven by through bacterial cultures and report them with brief review of the related literatures.

Thymoma is defined as a neoplasm of the epithelialreticular framework cells of the thymus. The treatment of choice and the prognosis for patients with thymoma are still controversial subjects due to lack of a uniform histological classification and standardized criteria for typing thymic tumors. Between June 1985 and May 1989, eight patients underwent thymomectomy at the Department of Thoracic and Cardiovascular Surgery, Korea University Medical Center. A clinical analysis was performed and the following result was obtained. In histologic cell type, epithelial type was 2 cases, lymphocytic type 3 cases, and mixed type was 3 cases. The clinical stage was classified by Masaoka’s classification that Stage I was 4 cases, Stage II; 2 cases, Stage III; 2 cases and Stage IV was none. Myasthenia Gravis was associated with thymoma in 5 patients. In 8 patients, thymomectomy were performed. Adjuvant radiotherapy was performed in one patient with Stage I due to suspicious tumor remnant and in Stage II, III patients routinely. Combined chemotherapy was performed in one patient with Stage III due to local recurrence. We concluded that the most important prognostic factor of thymoma is extent of tumor invasion. And the presence of Myasthenia Gravis is no more prognostic factor. Surgical resection of thymoma is treatment of choice, If local invasion or distant dissemination is present, postoperative radiotherapy and /or combined chemotherapy is recommended.

Since the diversification, complication of the construction industry, construction conflicts have been increased these days. Expansion of scale of construction has brought conflict treatment cost increase. Thus, needs of the study on construction conflict risk factors and its management is getting important. But the existing studies about construction conflicts and risk factors that need to be cared to decrease construction cost are almost focused on analysis of number of conflict proposed. It means those studies can be helpful when want to know how many conflict have been instituted, however, they do not contain a close examination between types of conflict and cost of conflict treatment. The purpose of this study, therefore, is an extraction of conflict causes based on the conflict treatment cost and the choice of significant risk factors to be managed to prevent conflict and its treatment cost, which enables reducing the conflict treatment colt on control the risk factors.

There are no standard consensus about treatment results and prognostic factors based on randomized trials for benign vocal fold lesion. Currently, voice therapy is the treatment of choice for vocal nodules, and laryngomicroscopic surgery is for vocal polyps. There are no strong evidences to support it, based on randomized controlled trials, But, it's just a consensus among laryngologist. Considering the pathophysiology of benign vocal cord lesions, cognitive behavioral therapy that corrects the patient's bad voice habits and improves their vocal hygiene could be most important factor for treatment outcomes.
