The goal of this article is to ascertain the factors that govern consumers' choosing to outbound travel product. The authors assess the consumers' travel product choosing processes with information search(internal knowledge, external information knowledge). alternative evaluation(perceived image, emotional experience, price acceptability, appeal, trust), and alternative choice(purchasing intention). Using data on Thailand travel product, the authors find considerable results and conclude by discussing prescriptive recommendations for the travel industry.

The authors study the asymptotic behavior of radial minimizers of an energy functional associated with ferromagnets and antiferromagnets in higher dimensions. The location of the zeros of the radial minimizer is discussed. Moreover, several uniform estimates for the radial minimizer are presented. Based on these estimates, the authors establish global convergence of radial minimizers.

Pharyngoesophageal diverticulum is a well-known disease entity but is seldomly reported in Korean literature. Recently the authors experienced two cases of pharyngoesophageal diverticulum. A 46 year old female and a 51 year old female patients were admitted due to foreign body sensation in esophagus and dysphagia. Preoperative esophagography and esophagoscopy confirmed the diagnosis of pharyngoesophageal diverticulum in each patient. The authors performed one-stage pharyngoesophageal diverticulectomy and myotomy. Postoperative esophagography revealed no diverticulum or stenosis and symptoms were markedly relieved.

The authors have been devoted to researches on fuzzy theories and their applications, especially control theory and application problems, for recent years. In this paper, the authors present results on a comparison of optimal solutions between ones of an ordinary-typed mathematical linear programming problem(O.M.I.P. problem) and ones of a Zimmerman-typed fuzzy mathematical linear programming problem (F.M.L.P. problem), and comment about the sensitivity (differences and fuzziness on between O.M.L.P. problem and F.M.L.P. problem) on optimal solutions of these mathematical linear programming problems.

Authors developed the computer application program (language: APPLE SOFT BASIC) for derivative spectrophotometry. By means of this program, derivative of spectral absorbance with respect to wavelength is recorded versus wavelength. To try this program in connection with spectrophotometer system, the authors have done the simultaneous quantitation of pyridoxine center dot HCl and nicotinamide in the mixture, and the result was compared with that of absorbance method.

Integrated Project Delivery (IPD) is a new trend in the building industry and a key feature of IPD is the use of BIM to support project collaboration. Therefore, engineers should learn the use of BIM and IPD in the construction industry. In this study, the authors draw necessary components for developing an IPD course curriculum through analyzing a project case and current courses provided by universities in Korea. The authors make several suggestions for effective IPD education in universities.

This is a design and analysis of the D.C. highly stabilized power source. This appratus has 10**-7 order of the voltage regulation and 40V, 1.5A, continuosly variable D.C. output. Authors inspected the effect of the OP Amp, FET and the load circuit to the stationary and transient characteristics of the apparatus. Authors found that it is a useful method for high performance of the stabilized power source to utilize IC OP Amp and FET as the elements of it.

This paper provides an experimental verification of an FRF-based structural damage identification method (SDIM) developed by the authors for beam structures. The FRF-based SDIM requires the following data : (1) natural frequencies and mode shapes measured at the intact state and (2) the FRF-data measured at the damaged state. Experiments are conducted for the cantilevered beam with one slot and three slots. It is shown that the FRF-based SDIM developed by the authors provide very successful damage identification results which agree well with true damage state.

Authors experienced a case of typical carcinoid in a patient of 46 year-old female who has been suffered from hemoptysis intermittently for 13 years. Exploratory thoracotomy and middle and lower lobectomy was carried out. The tumor was located in the right intermediate bronchus. Tissue pathology shows a glandular tumor with focal proliferation of Kulchitzky cells in the bronchial epithelium by H&E stain and membrane-bounded neurosecretory granules in the cytoplasm by electron microscope. Authors report the case with a literature reviews.

The authors had a case of large periodontal cyst treated by Apicoectomies in 32 year old, Korean female. 1. A large periodontal cyst revealed big size in Maxilla, left side. 2. The authors have treated the periodontal cyst by means of the apicoectomies of the involved left lateral incisor, canine, 1st premolar and 2nd premolar teeth, maxilla. 3. Radiographic examination revealed a large radiolucent lesion 2.7 3.7cm in diameter, in the midline area, with involvement of the lateral incisor, canine, 1st premolar and 2nd premolar teeth, maxilla.
