Malignant fibrous histiocytoma was classified as fibrosarcoma, liposarcoma, rhabdomyosarcoma in times past and it was first introduced in 1963 to refer to a group of soft tissue tumors and reported in bone in 1972. It was postulated that the origin of tumor cell was derived from histiocytes that could assume the appearance and function of fibroblasts("facultative fibroblasts") at first. But, recently the immunohistochemical studies suggested origin from a primitive mesenchymal cell. The malignant fibrous histiocytoma were commonly misdiagnosed as other tumors such as myxoid liposarcoma, pleomorphic rhabdomyosarcoma, osteogenic sarcoma, leiomyosarcoma, malignant schwannoma, giant cell tumor, hemangiopericytoma, dermatofibrosarcoma protuberans due to the broad morphologic spectrum. The seventeen cases of the malignant fibrous histiocytomas diagnosed at Hanyang University Hospital since 1979 were reviwed, and the suggestions are as follows : 1. No fundamental histologic differences between the MFHs of soft tissues and bones. 2. The other tumors must be excluded in order to diagnose MFH due to wide histologic variety of MFH. 3. The review of the initial tissue slide was necessary for adequate diagnosis because the recurrent MFHs showed different histologic findings from original tumors.

It is already recognized, the fleet crew of Korean Coast Guard(KCG) have come to perform a wide range of roles that they carry on duties on inferior working conditions. Therefore a research on leadership is seemed necessary to improve organizational effectiveness for them. This study is to examine whether leadership style with transformation is appropriate in organizational commitment for the fleet crew of KCG. In this study transformational leadership is fixed as independent variables and organizational commitment as dependent variables and also five factors as demographic characteristics. Intellectual stimulation is turned out to be the most influential factor in organizational objective(t=6.664, p=0.000) and continuance commitment(t=4.057, p=0.000), but individualized consideration are uninfluential factors concerning organizational commitment.

This paper offers a method to measure the distribution of niches of two types of social organizations. Internet sites and voluntary organizations. based on the socio-demographic characteristics of their members. It examines the niches of Internet sites based on age and education of site visitors and those of voluntary organizations based on age. education. and occupational prestige of their members. The method to measure organizational niches makes it possible not only to understand the niche width of organizations but also to examine the extent to which organizations .potentially compete and coexist. This leads to a method to recognize the way organizational environments influence the performance of individual organizations ecologically. To conclude, this paper shows that organizations are socially embedded through a process of pariticipation in which individual members choose their organizations not randomly. but based on their socIoifemographiccharacteristics.

Sonoelastography is an ultrasound-based technique that visualizes the elastic properties of soft tissues by measuring the tissue motion generated by an externally applied vibration. In this paper. the characteristics of wave generation in soft tissues due to an acoustic vibrator are studied. The effects of modal patterns on the detectability of lesions such as tumors in senoelastography are also investigated These are accomplished by analyzing the vibration patterns calculated using theoretical equations and finite element methods in halt space, infinite plate. and finite-sized tissue. A finite-width source generates shear waves with large amplitude Propagating in specific directions. and the generation characteristics depend both on the width and frequency of the vibrator. as well as the distance from it. It is shown in a finite-sized tissue that the lesion detection in displacement images is quit dependent on the modal patterns inside tissue. In contrast it Is also found that the lesion detectability in strain images is less dependent on the modal Patterns and is much better than that in displacement images.

Recent accidents of customer information leakage increase the necessity of information security for organization and the importance of information security team for it. To strengthen information security, organizations make information security policy and ask the members to comply with it. In this regard, maritime organization also needs to structure information security policy and examine its ability and behavior. The purpose of this study is to analyze the effects of compliance with information security policy on the ability and behavior of workers in shipping and port organization. The results of investigation show that information security education and norm affect compliance with information security of the workers. On the contrary, the punishment of information security is insignificant. It is shown that the degree of compliance with information security significantly affects its ability and behavior of the workers in shipping and port organization.
