Background: Recent advance in video technology, endoscopic equipments, and surgical techniques have expanded the use of thoracoscopy from diagnosis of the pleural diseases to treatment of the various intrathoracic diseases. Video Assisted Thoracoscopic Surgery(VATS) is a pretty new and fascinating thoracic surgical modality, and so we present our early VATS resuls. Methods: Using Video Thoracoscopic techniques in 30 patients for 10 months from July 1992 to April 1993, we had performed a variety of procedures. These incuded (1) bleb resections in 18 patients (19 cases), (2) mediastinal tumor excision in 4, (3) lung biopsies for parenchymal pulmonary disease in 3, (4) pleural biopasies in 3, (5) pleural tumor excision in 1, (6) and pleuropericardial window in 1. Results: There were no mortality associated with the procedures. We had minor 8 complications; prolonged air leak in 3 patients, prolonged serous drainage in 2, recurrence of pneumothorax in 1, Honer's syndrome in 1, and hoarseness in 1 patient. None of the 30 patients had reverted to the conventional full thoracotomies. Mean postoperative hospital stay of non-complicated pneumothoraces was about 5 days, which was a little shorter than conventional thoracotomy group. Conclusion: Though we had somewhat higher postoperative complication rate due to lack of experiences in the begining, we were able to convince that VATS had benifical value for patients; lesser postoperative pain, shorter hospitalization, quicker recovery time, and cosmetically superior scar. The role of VATS can be expanded to the diagnosis and treatment of various thoracic diseases, even to the cardiovascular diseases, with satisfactory outcome and less postoperative morbidity.

The lungs are frequently the site of adverse drug reactions because of their higher oxygen concentration, the distinctive properties of the pulmonary circulation, and the close proximity of the alveolar epithelium to the blood. Amiodarone, an iodinated benzofuran derivative, is an effective antiarrhythmic drug commonly used for refractory tachyarrhythmia. However, it has a wide range of adverse effects, the most serious of which is lung disease. Most patients present with the insidious onset of dyspnea and a nonproductive cough, and generally recover after withdrawing the drug. We recently experienced four fatal cases of amiodarone pulmonary toxicity. Therefore, we discuss these unusual drug-induced pulmonary toxicity cases with a review of the relevant literature.

Pulmonary aneurysm is a rare vascular anomaly.Infection is one of major causes of pulmonary aneurysms. Pulmonary aneurysm by pulmonary actinomycosis is a rare case. Our case is maybe the first case in Korea,so far similar case has not been reported Worldwide written in English. We describe a 73-year-old man with aneurysm of pulmonary artery caused by actinomycosis infection on lung. We detected aneurysm by angiography of pulmonary artery, and actinomycosis infection was revealed by confirm sulfur granules on specimens taken by percutaneous needle aspiration(PCNA). Antibiotic therapy was applied to this patient and aneurym was embolized with coils.With this therapy,the patient was successfully managed and improved.

Many classes of drug, such as antineoplastic drugs and antiarrhythmic drugs, have potential to induce interstitial lung disease. Herbal medicines are also believed to have the potential to induce pneumonitis. However, to our knowledge, there are no reports of pneumonitis caused by herbal medications in the Korean medical database. We report a case of recurrent pneumonitis caused by a self rechallenge of the Herbal medicine Bojungikgitang (Bu-Zhong-Yi-Qi-Tang : Hochu-ekki-to).

There are few reports of the pleuropulmonary involvement of a non-typhi Salmonella infection in immunocompromised patients with AIDS, malignancy, collagen vascular diseases, extended use of corticosteroids, sickle cell disease, or diabetes. We report a case of a non-immunocompromised patient who presented with concomitant empyema and mediastinitis due to Salmonella without a comorbid disease. A 26-year-old male patient, with a history of pneumonia 5 years earlier and having lived abroad for several years, presented chronic cough and febrile sensation. Pneumonia, empyema and mediastinitis were noted in a chest CT scan and Salmonella enteritidis and ${\beta}-hemolytic$ streptococcus were identified from a culture of the pleural fluid. Initially, he was treated with cefepime, metronidazole and clarithromycin. He was cured clinically and radiographically after an 8 week treatment with antibiotics. In conclusion, this report suggests that S. enteritidis can cause empyema and mediastinitis, albeit rarely.

This study was conducted to investigate the convergence effects of key vocational competency on career decision making in dental hygiene students. To this end, 196 students with an experience of clinical field training, who were enrolled in the department of dental hygiene in universities of Busan and Ulsan area. The collected data were analyzed by frequency analysis, correlation analysis and linear regression analysis using SPSS 24.0 program. The subjects' awareness level of key vocational competency was 3.38 points, while that of career decision making was 3.30 points. Among the sub-factors of key vocational competency, the awareness level of professional ethics was 3.46 points, which was the highest. As factors of key vocational competency affecting career decision making, interpersonal skills(p<0.01), skills for understanding groups(p<0.01), resource management skills(p<0.01), self-development skills(p<0.05), problem-solving skills(p<0.05), and mathematical skills(p<0.05) were found to be significant. It is necessary to make student individual, departmental, and university level convergence efforts and to develop curriculum so that dental hygiene education can help students equip with the key vocational competency as well as major competency.

One of the nonlinear statistical modelling, neural network method was applied to predict the Sea Surface Temperature Anomalies (SSTA) in the Nino regions, which represent El Nino indices. The data used as inputs in the training step of neural network model were the first seven empirical orthogonal functions in the tropical Pacific $(120^{\circ}\;E,\;20^{\circ}\;S-20^{\circ}\;N)$ obtained from the NCEP/NCAR reanalysis data. The period of 1951 to 1993 was adopted for the training of neural network model, and the period 1994 to 2003 for the forecasting validation. Forecasting results suggested that neural network models were resonable for SSTA forecasting until 9-month lead time. They also predicted greatly the development and decay of strong E1 Nino occurred in 1997-1998 years. Especially, Nino3 region appeared to be the best forecast region, while the forecast skills rapidly decreased since 9-month lead time. However, in the Nino1+2 region where they are relatively low by the influence of local effects, they did not decrease even after 9-month lead time.

This research is focused on the inducement of the constitutive equation considering the creep strain component and on the development of a finite element method program. The purpose of this research was to contribute to the design of construction structures or to the construction management in soft clay ground through predicting the long-term strain of construction structures reasonably bused on the above program. Modified Cam Clay model was adopted to describe the elastic-plastic behavior of clayey soil. And in the calculation of the creep sprain, the secondary coefficient of consolidation C. was applied for considering the volumetric creep element and the constants m, $\alpha$, A were rosed by the empirical creep equation proposed by Singh 8E Mitchell for considering the deviatoric creep element. To examine the reliability of the program which is developed in this study, the estimated values by this program were compared with the theoretical solution and the experimental results. And the applicability of the developed program was found to be reliable from the sensitive analysis of each parameters used in this study. According to the results obtained from the application of the program on the field measurement data, the estimated values by the program were found with be consistent with the actual values. And from the analysis of the displacement of embankments, the case of considering the creep behavior induced much fower errors than the case of neglecting it. But the results obtained from considering the volumetric creep behavior only were slightly underestimated the results from considering the deviator creep behavior showed the slightly overestimated values. Therefore, it remains the task of further studios to develop the laboratory test devices to obtain the reliable creep parameters, and to select the appropriate soil parameters, etc.

The purpose of the study was investigated on that whether there was any statistical difference or not in terms of the career decision making according to the growth environment of High school students. The researcher surveyed 600 questionnaires for high school students and was using 539 questionnaires in the final analysis. They were analyzed by cluster analyses according to the growth environment scale and it classified into two cluster groups. The cluster group A and B had a significant difference on scores of the growth environment scale. The group A had more interested in activities such as political, social, intellectual, and cultural ones and participated at social and leisure activities. Moreover, the group was emphasis on moral and religious values. The group B got the higher score than group A about the score of the rational type of the career decision making: the group A got the higher score than the group B to the score of the dependent type. On the matter of the job information collection sub-scale, the group A got the higher score than the group B: the group A scored higher points than group B about the goal establishment and the self-estimate sub-scales. Therefore, in order to do the career-guidance of youths, each family had to provide positive growth environment which required various stimuli and affluent in experience settings for them to mature.
