A total of 164 individuals of Hippocampus coronatus were collected from an eelgrass bed in Dongdae Bay, Korea from September 2006 to August 2007. The number of individuals of H. coronatus was higher in September 2006. The size of H. coronatus ranged from 2.4 to 9.3cm in height (Ht), and most of individuals were small size below 5cm (Ht). H. coronatus was a carnivore which consumed mainly gammarid amphipods and copepods. Its diets also included a small amount ofmysids, ostracods, brachiopods, caprellid amphipods, bathynellaceas, isopods, tanaids, and ascothoracids. The diets of H. coronatus underwent size-related changes; smaller individuals consumed copepods, while larger individuals ate gammarid amphipods and mysids. The dietary breadth index of H. coronatus was increased with increasing of their size.

Purpose: This study examines areal composition of ward applying to 4 bedroom in provincial medical center. Methods: The existing five-bed patient rooms, general type of multiple-bed rooms in Korea causes many problems for the amenity of patients. We should reconsider their inconvenience carefully and try to provide the right to keep their privacy and enjoy amenity. The number of patients of multi-bed rooms is very critical point to improve the environmental condition of the patient rooms. This study separate 5 bedroom group and 4 bedroom group. Net area from space program was surveyed and analyzed. Results: The result of this study can be summarized into two points. The first one is that Group-4(4 bedroom) ward has more 23% patient's area and -23% convenience area than Group-5(5 bedroom). The second one is that Group-4 has more single bedroom and Group-5 has more dayroom. Implications: Consideration Should be taken into account for the effective bedroom composition and allocation in ward. This Study hopefully may serve as a stepping stone for the standard design of space program in ward.

Purpose: At the moment, a lot of Public Hospitals in Korea have adopted 5 or 6 bedrooms as a standard multi-bedroom type. However 5-6 bedrooms have many problems related to inpatient satisfaction and nosocomial diseases. Therefore 4 bedroom is under considering for standard multi-bed room in Public Hospitals in Korea. This paper tries to prove that adoption of 4 bedroom in Public Hospitals has nothing to do with economic loss which is now an obstacle in adopting 4 bedrooms. Methods: 3 Methods have been used in this paper. 1) Comparative analysis between medical insurance fee and service cost for hospitalization has been conducted through literature survey. 2) Scenario analysis has been used for the estimation of inpatient number when 4 bedrooms are adopted in Public Hospitals. 3) Relation analysis between profit and proportion of 4 bedroom in Public Hospitals. Results: Adoption of 4 bedroom as a standard multi-bedroom in Public Hospitals has been proved to have nothing to do with the economic loss of hospitals. Implications: It is necessary to introduce and expand 4 bedrooms instead of 5-6 bedrooms in hospitals for the upgrade of hospital environment and easy control of cross infection in inpatient bedrooms.

A number of experiments were conducted in order to investigate the organic removal efficiency and biomass characteristics according to the organic shock loading rate in a fluidized bed biofilm reactor. At the operation conditions of HRT, 8.44 hour, superficial upflow velocity, 0.9 cm/sec and temperature, 22$\pm$$1^{\circ}C$, the removal efficiency of SCOD was founded to be 96.5, 92 and 90 % with the organic shock loading rate of 3.5, 10.8 and 33 kgCOD/m$^3$ㆍday, respectively. Within the F/M ratio ranged 0.4 to 2.0 kgCOD/kgVSSㆍday, the SCOD removal efficiency was shown as 90% at F/M ratio of 2.0 kgCOD/kgVSSㆍday, but the TCOD removal efficiency was 72 % at F/M ratio of 1.8 kgCOD/kgVSSㆍday. The average biomass concentrations were 7800, 14950 and 27532 mg/l on the organic shock loading rate of 3.5, 10.8 and 33 kgCOD/$\textrm{m}^3$ㆍday, respectively. This result was agreed with the fact that more biomass could be produced at high concentration of substrate, but some biomass was detached at the onset of shock and easily acclimated at the shock condition.

A data transform is performed by using a point-electrode focusing method in order to obtain accurate and objective interpretation of the borehole normal resistivity data. Two new synthetic curves can be generated through the data transform. The one is an approximate apparent resistivity curve, which would be used to predict the true resistivity of the formation. The other one is a bed boundary coefficient curve, which would be used to distinguish bed boundaries. The accuracy of the normal data interpretation can be improved and this method takes much less computational time than a linear inversion technique. Moreover, this method does not require an initial guess model and limitation of number of unknown parameters. Since this algorithm can be run on a personal computer, an immediate interpretation would be possible at the field work site. If an additional set of electrodes(a=125cm)is attached to a normal resistivity tool which is being used (a=25cm, 50cm, 100cm), the apparent resistivity for the point-electrode focusing device can be calculated, and it would maximize the use of short and long normal resistivity data and promote the accuracy of the interpretation.

The wind generated circulation model describes the phenomenon based on the following physical assumptions: a) As the horizontal dimension of the flow domain is several orders of magnitude larger than vertical dimension, nearly horizontal flow is realistic. b) The time taken for circulation to develop may effect on the flow domain of the earth's rotation, the contribution of the Coriolis force. c) A flow domain of large dimension results in quite large Reynolds number and the Reynolds stresses are approximated by the turbulent mean velocity gradient. d) The circulation is forced by the shear stresses on the water surface exercised by the wind. Modification made to the depth average approximation of the convective terms and the bed shear stress terms by adopting a certain distribution of current over the depth and laboratory measurements for the bed shear expression. Modification circulation patterns, energy evolution and surface profile gave the significant differences comparing with the classical model results. The modified model results in higher free surface gradients balancing both the free surface shear and the bed shear and consequently to higher surface profiles along the coast.

This paper presents a set of results of plate load tests that imposed incremental cyclic loading to a sandy soil bed containing multiple layers of granulated rubber-soil mixture (RSM) at large model scale. Loading and unloading cycles were applied with amplitudes incrementally increasing from 140 to 700 kPa in five steps. A thickness of the RSM layer of approximately 0.4 times the footing diameter was found to deliver the minimum total and residual settlements, irrespective of the level of applied cyclic load. Both the total and residual settlements decrease with increase in the number of RSM layers, regardless of the level of applied cyclic load, but the rate of reduction in both settlements reduces with increase in the number of RSM layers. When the thickness of the RSM layer is smaller, or larger, settlements increase and, at large thicknesses may even exceed those of untreated soil. Layers of the RSM reduced the vertical stress transferred through the foundation depth by distributing the load over a wider area. With the inclusion of RSM layers, the coefficient of elastic uniform compression decreases by a factor of around 3-4. A softer response was obtained when more RSM layers were included beneath the footing damping capacity improves appreciably when the sand bed incorporates RSM layers. Numerical modeling using "FLAC-3D" confirms that multiple RSM layers will improve the performance of a foundation under heavy loading.
