Fluorescent receptors have gained much attention because of their usefulness in analysis and clarification of the roles of biomolecules in living systems. Molecular structures of the integrated type including that the receptor itself is fluorescent, and play an important role in having the functionality or selectivity of the fluorescent compounds. These spaced type fluorescent receptors are required to have special molecular design in order to transmit the information of molecular recognition to the fluorescent unit through the spacer unit. Compared with the spaced type fluorescent receptors, number of the integrated type receptors is limited due to the difficult molecular design and synthesis. Modification of alteration of the fluorophore frequently caused deterioration of the fluorescent property. Various spaced type and integrated type fluorescent receptors including switch on-off receptors are introduced in this article.

Recently the hospitals or clinics tend to get out of the functional and technological aspect so as to gradually emphasize service for patients. While qualitative rather than quantitative alteration is noticeable, the scale of clinics is getting larger. Especially, the opulence resulted from economic, social and cultural development has enabled more people to visit dermatology or plastic surgery besides treatment for disease. Responding to this tendency, dermatology is focusing on skin beauty, plastic operation, controlling obesity, etc. for women rather than ordinary treatment. Thus, dermatology is in need of space for skin control as well as ordinary treatment, which raises the immediate necessity of new plan for space and interior environment. In order to meet such necessity of dermatology, it is required to fully study and consider the plan for interior space. First, the purpose, scope and method of research will be defined in the introduction. Second, the concept of clinic as well at the characteristic of dermatology will be studied by theoretical investigation. Third, the general concept of dermatology will be analyzed by examining the characteristic of each room in dermatology, the moving line of nurses and patients, the color of dermatology and the design factor of finishing materials through general investigation on dermatology. Fourth, in order to look into the general case of dermatology, the object of examination will be selected for examination through literature and visiting. After examining data, the result will be analyzed and evaluated to prepare the ground for interior plan of dermatology.

The vertical lathe is a very popular machine tool in modem manufacturing industries because of its small area of installation. The small installation area is highly desirable for the flexibility improvement of the manufacturing systems such as FMS, CIM, and IMS. The vertical lathe, however, has much taller height compared to the traditional horizontal lathe, and consequently more severe vibrations. In this study, the structure of a vertical lathe is analyzed to investigate the dynamic properties and further to establish some ideas of the design alteration for the improved dynamic stability even at the higher operating speed. The simulation model is implemented to apply those design alterations for the optimization. The result of this study is not only prosperous but also ready to be applied to the optimum design of various machine tool structures for the improved stability.

In recent years, the solar cell market has steadily grown with the demand for new energies. And wire sawing is one of the most critical processes in manufacturing solar cell wafer which is supposed to affect the breakage of wafers most during the process and afterwards. Generally, the defects of the wafers are generated from the structural vibrations of the machine. In the sawing process, the vibrations cause unnecessary normal stress on the cut surface of wafers, and eventually create the surface damage or leave the residual stress. In this study, the dynamic properties of a wire saw have been analyzed through the frequency response test and the computer simulation. And the effects of the design alterations have been investigated to stabilize the machine structure and further to reduce the vibrations. The result shows that relatively simple design alterations of supporting structure without any change of major parts of the machine can suppress the vibrations of the machine effectively.
