In case the wastewater contained various pollutants was treated with the complex oxidation treatment method utilizing the ozone and ultra-violet radiation, the removal rates of BOD, COD, SS, Tirbidity and E.Coli according to the ozone contact concentration were excellent. The following conclusions were obtained from the experimental results : 1. When the ozone contact concentration was above 12.lmg/l, the BOD removal rate and the effluent BOD concentration were above 90% and below 10mg/l, and then the COD removal rate was above 90%, also. 2. When the ozone contact concentration was above 12.lmg/l, the SS removal rate was about 60% at 40, 50 mins. of hydraulic retention time, but the removal rate was down to 40% at 60mins. of HRT. 3. When the ozone contact concentration was above 5.2mg/l, the E.Coli removal rate was about 100% without the hydraulic retention time.

The effects of various sugars and amino acids of the stability of the plam oil in Ramyon, was studied. Stability of the palm oil in Ramyon was determined from acid, peroxide, anisidine values and color development. The effects of sugars added on the stability of the palm oil in Ramyon was in order of arabinose, xylose, glucose, fructose, lactose, sucrose, raffinose. In addition of amino acids and glucose, the stability of the palm oil in Ramyon showed a significant increase in order of β-alanine, glycine, valine, lysine, but threonine and glutamic acid showed less stability. The effects of glycine concentration on the stability was increased to 0.5%. After deep-fried, color developments of Ramy on surface increased in darkness to 0.5% glycine concentration and decreased during the storage period.

Glycololeates for the application of cutting fluid were synthesized from oleic acid and glycols such as ethylene glycol, diethylene glycol and triethylene glycol. The ratio of glycol-monooleate and dioleate in product according to the reaction condition was analyzed by TLC, CC and HPLC. Properties of glycololeates as cutting fluid were examined by various testing methods such as profile test, pH test, anti-foaming test friction coefficient test and emulsion stability test to compare those of base oil and cutting fluid trading in the market. Non-catalytic reaction of glycololeates synthesis was showed too low conversion rate, but too fast conversion rate and deep color deterioration of products was obtained with acid-catalyses reaction. Using the SnCl2 catalyst, conversion rate was medium range and products which suitable for the application of cutting fluid with mild colored and with desirable mono- and di-oleate composition was obtained. Cutting fluidal properties of glycololeates with SnCl2 catalyst were better than those of base oil, and were similar level to those of cutting fluid containing various additives.

The objective is to develope a long term care medel in Young-Ju City. I analyzed annual report of Young-Ju City in 2001. Currently many countries are widely perceived the rising percentage of older people in the population. Many older people suffer from combinations of different diseases and treatment of each condition is complicated by the presence of others. Many diseases that affect older people cannot be solved by acute but require chronic care extending over months and years. For all but the most sick people this care can be delivered in a domestic environment, and most older people wish to remain in their homes as long as possible. So far so good, but by the time that these older people have reached home or been placed in a care home. Followings are the results of the analysis. 1. Centering around with health center, public and private resources in the community must be integrated and closed linked. Health center must play a role in case manager and direct service provider to effectively drive long term care program. 2. Through the integration of health center and department of social welfare in a city office, related resources must be used efficiently, mutual intervention and business linkage must be performed smoothly. 3. First of all, decision-makers must perceive need and importance of long term care. 4. To provide continuously, long term care program needs a clear, consistent national policy to guide the partnership between public and private provision.

It is well known that double integration of measured acceleration records is one of the most difficult signal processing, particularly in the case of measurements on civil engineering structures. The measured accelerations on civil structures usually contain non-gaussian and low-frequency noises as well as acceleration records are non-stationary. For this type of signals, wavelet transform can be useful because of its inherent processing abilities for non-stationary signals. In this paper, the de-noising algorithm using the wavelet transform are slightly extended to process non-gaussian and low frequency noises, using median filter concepts. The example studies show that the intergration can be improved using proposed method.

In today's highly competitive hospital marketplace, a hospital must build a successful customer management system. Hospital database can drive strategies that will lengthen a hospital's relationship with its customers and increase the sales and term profitability of its business. The purpose of this paper is to explores what is the definition of database marketing and finds how to develope the database marketing strategies in hospital. Database marketing aims at increasing customer loyalty, retention, referrals, sales and profits. Database marketing consists of building a marketing database of customers and prospects. The database contains their names, addresses, demographics, purchases, web activity and promotion history. It is used to analyse customers, and to direct the company's customers and prospect communications programmers. There is a1so a need for clear marketing strategies that can be applied to hospital. This is to support customer retention, cross-selling and up-selling opportunities to improve direct/continuous marketing campaigns, and to put the hospital on the road to marketing one to one.

Comtemporary approach to moral education emphasize propositional thinking and socratestic verbal discussion of abstract moral dilemmas. In contrast, this article proposes that narratives are a central factor in moral education and feministi moral education. Support for this position comes from recent theoretical contributions of Bruner, Hoffman, Maclntyre, Gilligan and others, who have emphasized narrative thought as a major form of cognition that is qualitatively different from abstract propositional thinking. By the way, narrative has the opposing two aspects regarding gender equality, both of liberating and repressive effects on moral education. Narrative method of character education and virtue education is related to the traditional male values. In this respect, narrative becomes a repressive space for women. However, women can make narrative as a liberating space for them by promoting gender equality. It is proposed that narratives and narrative thinking are especially involved in how these processes lead to moral development and therefore that narrative should be rehabilitated as a valuable part of feministi moral education.
