A reliability analysis model is developed for evaluating the crest freeboard of vertical breakwaters based on the concepts of maximum overtopping volume of individual wave. A reliability function is formulated by defining the margin of admissible overtopping volume and maximum overtopping volume that is depend on the number of overtopping waves, dimensionless crest freeboard, and mean overtopping discharge. In addition, Level III MCS technique is straightforwardly suggested by which the related empirical parameters to reliability function can be considered to be random variables with the wide range of different uncertainties. It can be possible to calculate the probabilities of failure according to the relative crest freeboard with the variations of the incident wave directions, the structural types of vertical breakwaters, and admissible overtopping volumes in conditions of the long and short crested-waves.

Loss has been expanded to include not only death but also the change that take place in the transition of life. In addition, the rate of direct and indirect experience of death around us has increased due to natural disasters and unexpected accidents. Therefore, there is a growing demand for grief counseling and a need for professional grief counseling. The purpose of this study was to investigate the competency of grief counselors and to review on the literatures what grief counselors should be trained to improve their professional competences. Specifically, there were grief counseling theory, evaluation of grief, death education, and counselor self-care. There were suggested that how to integrate into existing counselor curriculum and introduced experiential practice. This study can be used as a basic data for encouraging the attention of grief counselor education and competency model.

In this paper, a theoretical model that separates one single conversion factor into two conversion factors for both outpatients and inpatients is introduced. By using hypothetical numbers, two conversion factors and an adjustment factor were calculated. The major implications are as follows. Firstly, by introducing two conversion factors, a minimum incentive mechanism for admitting outpatients to a clinic and high risk inpatients to a hospital was installed. Secondly, the introduction of two conversion factors decreased the drive to admit outpatients to a hospital by reducing the economic benefits for the hospital. Thirdly, it is possible to make explicit contracts for several factors rather than a single conversion factor, so that it can be used as an appropriate management tool for rapidly increasing medical expenses. Finally, this research can be used to set up policy tools to establish a proper healthcare delivery system in Korea by inducing behavioral changes in healthcare institutions.

The writers study on the development and the prospect of computer map based on the most recent computer mapping technical aspects. We also study domestic prospect of computer map in connection with the present condition of domestic GIS. The main results are as follows: (1) Computer map has rapidly developed in spite of its short history. We expect that computer map will be improved more in the future owing to the development of computer hardware and software. Most mapping processes will be possible sooner or later owing to Artificial Intelligence(AI) and more improved scanner without human effort. (2) Computer map can be used for various industrial fields and its development can give a great help for technical advance in correlated industries. (3) Computer map has really developed in the country since 1980, when GIS was introduced. Especially, government planned to digitalize all the basic topographical maps covering the whole country between 1996-1998. We think that there is an epoch-making change in the development history of computer map in the future. (4) The development of GIS is closely connected with one of computer map, but the recent technical levels of GIS is not perfect. So there is an urgent need for technical supplement to produce good computer maps. (5) The government had better construct GIS database in order to cut down expenses derived from overlapping input of data by individual users and there is a need for data standard.

The purpose of the present study was to examine psychometric properties of the BSI-18 in Korean adults with mental disorders. This study examined internal consistency, test-retest reliability, convergent validity, and a factor structure of the BSI. The sample consisted of 180 adults with mental disorders, who enrolled in mental hospitals and in a day hospital. Data was analysed using reliability analysis, correlation analysis, and confirmatory factor analysis. Major findings were as follows. The Korean version of the BSI showed good internal consistency and test-retest reliability, as well as excellent convergent validity. The original three-factor structure of the BSI-18, proposed by Derogatis, 2001, fitted to the data. These findings indicate that the BSI-18 is a reliable and valid measure as a psychiatric assessment tool and a treatment outcome measure.

Temporomandibular disorders(TMD) have been defined as a collective term embracing a number of clinical problems that involve the temporomandibular joint, the masticatory muscles, and associated structures. Since Dr. Costen, an otolaryngologist, published his article in 1934 claiming that pain in and around the jaw and "related ear symptoms" improved with alteration of the bite, diagnosis and treatment of temporomandibular disorders(TMD) have been within the concept of occlusion. However most of the modern descriptions for TMD no longer include occlusal disorders within their domain. Despite this trend toward the exclusion of occlusal disorders from TMD domain, the historical linkages between TMD and occlusal therapy are still strong. Currently the most popular theories regarding TMD etiology are based on the biopsychosocial model. In the future, treatment modalities should be directed at the pathophysiological processes of joint and muscle pain as well as the psychosocial aspects of chronic pain.

The space of IID([ndependently, Identically Distributed) textures was built with axes of mean luminance and contrast, and studied on what kind of mechanisms were required to mediate texture segregation in this space. The conjecture was tested that one of these mechanisms is sensitive to the differences between the means of textures to be discriminated, whereas the other is sensitive to the differences between variances. The probability of discrimination was measured for various pairs of textures in the lID space The data were well fit by a model in which discrimination depends on two mechanisms whose responses are combined by probability summation. The conjecture was rejected that two mechanisms respectively tuned to mean and variance of texture function in segregation. Discrimination within space is mediated by 2 independent channels however: the 2 independent channels are not exactly tuned to texture mean and variance. One m mechanism was primarily sensitive to texture mean, whereas the other was sensitive to b both texture mean and variance.

A flow determination algorithm is proposed for the distributed hydrologic model. The advantages of a single flow direction scheme and multiple flow direction schemes are selectively considered to address the drawbacks of existing algorithms. A spatially varied flow apportioning factor is introduced in order to accommodate the accumulated area from upslope cells. The channel initiation threshold area(CIT) concept is expanded and integrated into the spatially distributed flow apportioning algorithm in order to delineate a realistic channel network. An application of a field example suggests that the linearly distributed flow apportioning scheme provides some advantages over existing approaches, such as the relaxation of over-dissipation problems near channel cells, the connectivity feature of river cells, the continuity of saturated areas and the negligence of the optimization of few parameters in existing algorithms. The effects of grid sizes are explored spatially as well as statistically.

Analytical solutions to predict the movement rate of submerged mound are derived using the convection coefficient and the joint distribution function of wave heights and periods. Assuming that the sediment is moved onshore due to the velocity asymmetry of Stokes' second order nonlinear wave theory, the micro-scale bedload transport equation is applied to the sediment conservation. The nonlinear convection-diffusion equation can then be obtained which governs the migration of submerged mound. The movement rate decreases exponentially with increasing the water depth, but the movement rate tends to increase as the spectral width parameter, $ u$ increases. In comparison of the analytical solution with the measured data, it is found that the analytical solution overestimates the movement rate. However, the agreement between the analytical solution and the measured data is encouraging since this over-estimation may be due to the inaccuracy of input data and the limitation of sediment transport model. In particular, the movement rates with respect to the water depth predicted by the analytical solution are in very good agreement with the estimated result using the discritization technique with the hindcast wave data.
