In a box girder, it is an accepted practice in structural engineering to represent the effect of 'shear lag' by adopting an 'effective width' concept. The actual width of flange plate (b) is replaced by a reduced width (b_e) over which the longitudinal stresses may be considered uniformly distributed and the application of the elementary theory of bending to the transformed girder cross section gives the correct value of maximum longitudinal stress (σ_max). This paper provides how to determine the magnitude of 'shear lag' and 'effective width ratio' in case of orthotropic box girder which is simply supported, symmetrically loaded only.

To develop the diagnostic method for the viral infection in apple, the partial genes corresponding to the N-terminal region of RNA polymerase of Apple stem grooving virus (ASGV) and coat protein of Apple chlorotic leaf spot virus (ACLSV) were characterized from the infected apple cultivars in Korea. Based on the nucleotide sequences of the characterized partial genes, the virus gene-specific primers were designed for the detection of ASGV and ACLSV infected in species of Malus. The RT-PCR using the primers for the genes of ASGV and ACLSV successfully gave rise to 404 and 566 bp DNA fragments, respectively. Using those viral gene-specific primers, the multiplex RT-PCR assays were also established to diagnose the mixed infection by ASGV and ACLSV simultaneously. Furthermore, the control primers, which have to be included for the RT-PCR as an internal control, were designed using the nucleotide sequence of the gene encoding elongation factor $1{\alpha}(EF1{\alpha})$. This multiplex RT-PCR including the control primers provides more reliable, rapid and sensitive assay for the detection of ASGV and ACLSV infected in Korean apple cultivars.

Respiratory bronchiolitis-associated interstitial lung disease (RB-ILD) is an inflammatory lung disorder associated with cigarette smoking. The clinical and radiographic findings of RB-ILD are nonspecific and most patients with RB-ILD are thought to have some form of idiopathic pulmonary fibrosis prior to lung biopsy. Open lung biopsy of patients with RB-ILD reveals inflammation of the respiratory bronchioles, filling of the bronchiolar lumens and surrounding alveoli with finely pigmented macrophages, associated interstitial inflammation. Alveolar septa, particularly around terminal and membranous bronchioles, are mildly fibrotic. We recently experienced a case of RB-ILD proven by open lung biopsy.

Idiopathic interstitial pneumonia (IIP) is a histologically identifiable pulmonary disease without a known cause that usually infiltrates the lung interstitium. IIP is largely classified into idiopathic pulmonary fibrosis, idiopathic non-specific interstitial pneumonia, respiratory bronchiolitis-interstitial lung disease (ILD), cryptogenic organizing pneumonia, desquamative interstitial pneumonia, and acute interstitial pneumonia. Each of these diseases has a different prognosis and requires specific treatment, and a multidisciplinary approach that combines chest high-resolution computed tomography (HRCT), histological findings, and clinical findings is necessary for their diagnosis. Diagnosis of IIP is made based on clinical presentation, chest HRCT findings, results of pulmonary function tests, and histological findings. For histological diagnosis, video-assisted thoracoscopic biopsy and transbronchial lung biopsy are used. In order to identify ILD associated with connective tissue disease, autoimmune antibody tests may also be necessary. Many biomarkers associated with disease prognosis have been recently discovered, and future research on their clinical significance is necessary. The diagnosis of ILD is difficult because patterns of ILD are both complicated and variable. Therefore, as with other diseases, accurate history taking and meticulous physical examination are crucial.

This paper describes the application of fuzzy algorithms to the control of processes with time delay. PI controller with Smith predictor has been developed to improve the response of the process with time delay. But this controller needs exact model and if the mismatch between model and process is large, the performance of the process is decreased. So this paper introduces the FLC(fuzzy logic controller) to remove these problems. The fuzzy control algorithm is used to implement linguistically expressed heuristic control policies directly, with a view to automating those complex and poorly-defined processes where modelling difficulties and lack of suitable measurments make manual control imperative. The FLC based on fuzzy set theory provides a means of converting a linguistic control strategy based on expert knowledge into an automatic control strategy. But conventional FLC is apt to generate the limit cycles in output response for a time-delayed process. The proposed FLC includes predictive model to eliminate those limit cycles at steady-state and to improve the transient response and robustness.

N/A Objectives: The humoral hypercalcemia of malignancy(HHM) describes a very specific clinical syndrome due to the production of a peptide or family of peptide hormones which share sequence homology and functional homology with parathyroid hormone. Patients with HHM account for up to 80 percent of malignancy-associated hypercalcemia. The hypercalcemia in lung cancer is mainly mediated by parathyroid hormone-related protein. Typical patients with HHM had little or no skeletal involvement. Hypercalcemia is predominantly associated with epidermoid and large cell anaplastic carcinoma. From a clinical standpoint, patients with hypercalcemia are usually in advanced stages with obviously bulky tumors and, therefore, carry a poor prognosis. Methods: Between January 1987 and November 1993, the patients those who fulfilled the following criteria were chosen as a subjects in this study: ① corrected serum calcium >10.5mg/dl; ② histologically proven primary lung cancer; ③ symptoms which could possibly be attributed to hypercalcemia. We investigated the various clinical features that could characterize the hypercalcemia in lung cancer. Results: Thirty-one patients with lung cancer were hypercalcemic and most of them had squamous cell carcinoma in histologic finding. The incidence between 50 and 69 years of age was higher significantly. The occurrence of hypercalcemia showed a strong positive correlation with the degree of histologic differentiation and the advancement of cancer stage. And the mean serum calcium level also showed a strong positive correlation with the mass size and the performance scale. Some symtoms such as general weakness, anorexia, constipation, consciousness change, and weight loss were more frequent in the patients of higher calcium level. There was no significant difference in effectiveness among the therapeutic regimens for hypercalcemia. Most of patients were hypercalcemic at the time that the diagnosis of lung cancer was made. Most of them died within 1 month after the development of hypercalcemia. Conclusion: The hypercalcemia in lung cancer was found more frequently in men whose ages were between 50 and 69 years old, and in the patients who had poorly differentiated squamous cell carcinoma or the carcinoma in advanced stage. Mean serum calcium level was higher in more symptomatic patients, and in the patients with worse performance scale or larger tumor mass. The prognosis of hypercalcemic patients with lung cancer was extremely poor.
