Conventional computer programs developed and used by practicing engineers can be considered to contain expert knowledge and design experience. If these conventional programs are converted into expert systems, the difficult and time consuming process of knowledge acquisition can be simplified. Also the constructed knowledge-base can have higher confidence level than that constructed by the usual knowledge acquisition method of interviews. An existing computer program which is being used by ship structural designers has been reformulated as a design expert system by applying an expert system development shell-Nexpert. Utilizing the callable interface provided by the development shell, external design tools have also been integrated. The interfaced external functions are a graphical user interface (GUI) for the design process control, and graphics functions for the visualization of design results. It is observed that the developed system for design support is useful in two aspects. The trace-back function shows what portion of design rules are applied in arriving at certain design decisions. Also the knowledge-base can be conveniently updated as design rules of the classification societies are updated.

The ocean contains around eighty elements of the periodic table and uranium is also one among them, with a uniform concentration of 3.3 ppb and a relative abundance factor of 23. With a large coastline, India has a large stake in exploiting the 4 billion tonnes of uranium locked in seawater. The development of radiation grafting techniques, which are useful in incorporating the required functional groups, has led to more efficient adsorbent preparations in various geometrical configurations. Separation based on a polymeric adsorbent is becoming an increasingly popular technique for the extraction of trace heavy metals from seawater. Radiation grafting has provided definite advantages over chemical grafting. Studies related to thermally bonded non woven porous polypropylene fiber sheet substrate characterization and parameters to incorporate specific groups such as acrylonitrile (AN) into polymer back bones have been investigated. The grafted polyacrylonitrile chains were chemically modified to convert acrylonitrile group into an amidoxime group, a chelating group responsible for heavy metal uptake from seawater/brine. The present work has been undertaken to concentrate heavy metal ions from lean solutions from constant potential sources only. A scheme was designed and developed for investigation of the recovery of heavy metal ions such as uranium and vanadium from seawater.

The purpose of this paper is to show that a shape pro-duced by natural factors such as weather, environments, etc., can be introduced into the emotion of a design, and to make a design process by planning a Korean image and characterizing its concept. Human beings, nature, man-made objects, and society have their own functions in an environmental structure. When all their functions are kept in working order, human beings come to discover orderliness out of which they can absorb pleasure. They cannot look into their own inside but they can trace back in their memories a variety of panoramic experiences which have been embed-ded onto their identity during their lifetime interactions with an empirical world. Children first acquire a way of cognition in the space, a comprehensive premise, connecting a specific place and an object of cognition. Such subconsciousness forms sky-lines of mountains, seas, and trees under the sky, and produces axis lines and beehived domes under the influ-ence of natural, cultural, and social factors, forming a folk culture. A subconscious composition of existential space is extended. A subconscious composition of existential space is extended to the areas of environmental design, product design, and fashion design. The development of a concept of place and space as a system is a necessary condition for discovering an existential foothold.

500 ml of a sample water was extracted with 10 ml of 0.01 % dithizone-$CHCl_3$three times. When $CHCl_3$ layer was back extracted with 10 ml of 0.1 N HCl containing mercuric ion, the free metal ions come into aqueous layer. The aqueous layer was added with 2 ml of 2 N KCl and was washed with 10 ㎖ of $CHCl_3$two times in order to remove the trace dithizone, and then was recorded square wave polarogram. The concentration of copper, lead and cadmium can be determined up to 3 ppb and that of zinc up to 14 ppb with an error of 10 %.

Objectives: There are many unknowns surrounding Jeong-Jo's death. To better understand Jeong-Jo's death, we closely inspected his medical records from the 20 days before his death in The Annals of the Chosun Dynasty (朝鮮王朝實錄) and Seungjeongwon Ilgi (承政院日記), Understanding medical treatment before death, we can correctly trace the cause of Jeong-Jo's death. Methods: According to The Annals of the Chosun Dynasty (朝鮮王朝實錄) and Seungjeongwon Ilgi (承政院日記), we examined his medical records between June 14 and June 28 of 1800, as to the change in chief complaint, cold and heat, thirst, syndrome differentiation, the opinions of Jeong-Jo, and the opinions of doctors, The original work, The Annals of the Chosun Dynasty and Seungjeongwon Ilgi were provided by NIKH (The National Institute of Korean History). The Korean translation of The Annals of the Chosun Dynasty was also provided by NIKH. Seungjeongwon Ilgi (original work written in Chinese characters) was directly translated into Korean by the study author. Results: 1. Jeong-Jo's is likely to have died of septicemia caused by an abscess on his back. 2. The cause of Jeong-Jo's death could be stroke due to hypertension, mental stress, and 'Wha (火) disease' Conclusions: The dominant view that Jeong-Jo was murdered by poison is not likely.

A gas chromatography/mass spectrometric assay method was developed for the simultaneous determination of ethylene glycol monomethyl ether (EGME) and diethylene glycol monomethyl ether (DEGME) in spilled aviation fuels. Ethylene glycol monobutyl ether (EGBE) and ethylene glycol monoethyl ether (EGEE) were used as internal standard and surrogate, respectively. The sample preparation consists of back-extraction with 7 mL of methylene chloride after extraction of 50 mL of fuel with 2 mL of water. The extract was concentrated to dryness and dissolved with 100L of methanol and analyzed by CC-MS (SIM). The peaks had good chromatographic properties by using semi-polar column and the extraction of these compounds from fuel also gave high recoveries of 75 and 85 % with small variations for EGME and DEGME, respectively. Method detection limits were 1.3 ng/mL for EGME and 1.0 ng/mL for DEGME in spilled fuel. The method may be useful for fuel-type differentiation between kerosene and JP-8, which may originate from the storage tank.

The medicinal plants have been used as drugs for thousands of years and many of them are used in traditional medicines. How long are these medicinal plants used as drugs\ulcorner Ebers papyrus (BC 1550) is one of the oldest documents which described more than 700 kinds of herbal drugs. Some of herbal medicines described in the papyrus are familiar and ‘Opium’ is a good example. Some of the drugs described in the papyrus are hardly recognized as drugs by the standard of present day. We can trace back the history of medicinal plants from quite different approach. The investigations on group behavior of chimpanzees in Africa by ‘The Primate Institute of Kyoto University’ has revealed that chimpanzees suffered illness take specific plants which are not taken as daily food stuff. The chemical analysis clarified that the plants contain very bitter constituents and suggested that chimpanzees take medicinal plants to cure their illness. It is worth to note that young chimpanzees just learn what elder ones take when they suffer illness, but elders never teach to their children! It is no doubt that the chimpanzee's medicinal plants were found by random, and try and error screening. The medicinal plants found in this study have been used as herbal medicines by the peoples in the region.

This Study is a research on symbolic meaning and artist's will of Vivienne Westwood's works which provide a new vision on woman's body and clothes. For the literary research, this study investigates theories of human's body which are phenomenal body of Merleau-Ponty's, the relations between power and body of M. Foucault's, cultural and social body of E. Goffman's and habitus of p, Bourdieu's. For the case research, Vivienne Westwood's collections are classified into each item which exaggerating and distorting woman's body such as Mini-Crini, corset, bustle cushion, bum-pad, farthingale and tailoring suits. Also she puts man's clothes item such as codpiece into woman's body. Through all of these design, she wants to reinterpret the woman's body and self-identity. Vivienne Westwood dose not leave the past just as a historic trace but recreates with her way of creation. Westwood has presented the satire which leads the parody of past in her unique ways of thinking and interpretation which mix the ideology of the past and the presents. Those make her look back the history and culture and express her esteem for self-identity of woman. Vivienne Westwood's works express woman's power and freedom in modem society.

A method was presented for the analysis of trace metals in iron oxide ore. The method utilized ammonium pyrrolidinedithiocarbamate (APDC)-methyl isobutyl ketone (MIBK) extraction procedure and analysis by atomic absorption spectroscopy (AA). Citrate at pH $8{\sim}10$ for the determination of Co, Ni and Cu or tiron at pH $6{\sim}7$for the determination of Mn and Cu was added as a masking agent to prevent extraction of Fe(III) into the organic phase. Reduction of solubility of MIBK in water was achieved by addition of NaCl as a salting-out agent. Back extraction of the MIBK extracts with aqueous $HNO_3$ was also studied to increase the stability of metal extracts.
