Time series data of oceanic and meteorological elements observed by Marine Research Institute, Cheju National University are used to investigate seasonal variabilities in oceanic and atmospheric conditions. Heat ?? elements at the sea surface are derived from the data of the marine meteological reports by applying an aerodynamical bulk method. The seasonal variation of serveral heat flux elements were abnormal during the analysed period(June,1993 ∼ September, 1995), and it might be related to global-scale changes in the ocean-atmosphere system. And the oceanic condition of the northern Cheju Island was sensitive to the insolated solar radiation.

This paper presents adaptive equalizer using LMS(least mean squares) algorithms for adaptive nonlinear filters equipped with bilinear system models. Bilinear models are attractive for adaptive filtering applications because they can approximate a large class of nonlinear systems adequately, and usually with considerable parsimony in the number of coefficients required. The severity of the ISI is directly related to the spectral characteristics of the channel and not necessarily to the time span of the ISI. This paper reduces ISI of the nonlinear channel. This paper generated a nember of data from a received signalwaveform with a symbol and proposed a new adaptive equalizer to update adaptive parameter from this data and method to use protocol analyzer.

UML is able to visualize and specialize the output of the system center of the software, and able to connect to various languages and is constructed by engineering/re-engineering. Also, UML is a standard Modeling Language that aims at the documentation. Recently Web Application System is quickly popular and gigantic, it's possible to do modeling using UML which is the method of Object-Oriented analysis and design and simplify the complex developing course of software. In this paper, we suggest the 『Post Seminar System』 model for instance Object-Oriented Web Application which can increase the efficiency of businesses through of exchanging information with members. We constitute web application by separating it into 3 steps such as View class which takes full charge of Screen Presentation, controller which plays the role of connecting ring and divergence of View class and Model class, and Model class that takes charge in the gear with the Application Logic and DB applying MVC model which has considerable merit in developing and maintaining the web application.

This study was carried out to evaluate the nutritional balance of recipes collected from five Day-Care Centers; three public and two private centers. Nutrient contents of recipes were evaluated by a self-developed computer program, focusing on the balance of 1) general nutrients, 2) fatty acids and 3) amino acids in lunch and afternoon snack for children aged 4 to 6. The average intake levels of calories, calcium, vitamin A were lower than the recommended levels of the RDA/3. The energy construction of carbohydrate, protein, and fat (CPF ratio) was 56:17:27. The subjects consumed 4.1g of polyunsaturated fatty acids, 2.6g of monounsaturated fatty acids, and 2.4g of saturated fatty acids per lunch and afternoon snack per day. The mean P/M/S ratio of dietary fat was 2.5/1.3/1 (recommendation: 1/1∼1.5/1). The mean ω6/ω3 ratio was 9/1 (desirable rage: 4/1∼10/1). The quality of fat and be improved by including ω3 fatty acid-rich foods such as bean products, seaweeds and fishes more frequently in the diet. Mean daily intake of cholesterol was 50㎎. Quantity and quality of dietary protein were reasonably fair. Varieties in nutritionally balanced menu should be emphasized more for children by nutrition professionals dietitians. It is of utmost importance to support early nutrition in national development and in improving quality of later life.

Adaptive hybrid position/force controller for constrained manipulator with uncer dynamic model parameters and environment stiffness is presented. In this paper, the complia frame model is constructed by independent positions and forces to be controlled. The adap controller based on this compliance frame dynamic model is designed. Lyapunov theory is u for contoller design and stability analysis.
