본 논문에서는 헬스케어시스템에서 효율적인 질병 관리를 위한 질병 규칙을 생성하는 질병규칙생성 기법(Disease Rule Creation Scheme)을 제안한다. DRCS는 기본적으로 Rough Set Theory의 개념을 이용하며, 각 속성과 결정 속성간의 지지율을 계산한다. 그리고 결정 속성을 기준으로 지지율이 낮은 속성은 제거한 후에, 질병을 판단할 수 있는 질병 규칙을 생성한다. 그 결과, DRCS는 C4.5알고리즘 보다 적은 질병규칙의 수를 생성하였으며, 질병 규칙의 정확성은 향상되었다.

A LOGIT transformation is a method to estimate IC50 values with two arbitrary concentration data when complete dose response curves(DRCs) are not available. We propose a modified LOGIT transformation (MLOGIT) which predicts IC50 values more accurately than the conventional LOGIT method.

This paper deals with the teletext systems with processing the Hangul which is compatible with the NABTS. The Hangul set was included in the graphic-set repertory of the 7bit in-use table and the synthesis method was used to process the Hangul codes. The Hangul in the Teletext systems by the NABTS is possible to use DRCS method, but the transmission delay problem has occurred in that case. As a result, all the programs within the NABTS format are possible to use without any modifications in this systems.

The aim of the present work was to investigate how colour changes of foal meat can vary after thawing out in relation to the slaughtering age of the horses and to the post-thawing time. Eighteen Italian Heavy Draught Horse (IHDH) foals were used for the trial. They were subdivided in three groups according to their slaughtering age (6, 11 and 18 months). Two different surfaces were investigated for each sample: a fresh cut surface (daily renewed cutting surface: DRCS), and not-renewed cutting surface (NRCS). The redness of both investigated surfaces increased with slaughtering age (p<0.01). Moreover, this parameter decreased during post-thawing time (p<0.01) only on the NRCS, probably due to the myoglobin oxidation processes. Colour is an important visual cue denoting perceived quality by consumers. So, by a chromatic perspective the thawed meat of IHDH foals slaughtered at 6 and 11 months proved to be that which best meets the market requirements.

An improved RRS (Reactor Regulating System) logic is implemented in this work using systems engineering approach along with GA (Genetic Algorithm) deemed as providing an optimal solution to a given system. The current system works desirably and has been contributed to the safe and stable NPP operation. However, during the ascent and decent section of the reactor power, the RRS output reveals a relatively high steady state error and the output also carries a considerable level of overshoot. In an attempt to consolidate conservatism and minimize the error, this research proposes applying genetic algorithm to RRS and suggests reconfiguring the system. Prior to the use of GA, reverse-engineering is implemented to build a Simulink-based RRS model and re-engineering is followed to apply the GA and to produce a newly-configured RRS generating an output that has a reduced steady state error and diminished overshoot level.

An improved Reactor Regulating System (RRS) logic architecture, which is combined with genetic algorithm (GA), is implemented in this work. It is devised to provide an optimal solution to the current RRS. The current system works desirably and has contributed to safe and stable nuclear power plant operation. However, during the ascent and descent section of the reactor power, the RRS output reveals a relatively high steady-state error, and the output also carries a considerable level of overshoot. In an attempt to consolidate conservatism and minimize the error, this work proposes to apply GA to RRS and suggests reconfiguring the system. Prior to the use of GA, reverse engineering is implemented to build a Simulink-based RRS model. Reengineering is followed to produce a newly configured RRS to generate an output that has a reduced steady-state error and diminished overshoot level. A full-scope APR1400 simulator is used to examine the dynamic behaviors of RRS and to build the RRS Simulink model.

Pakistan being the 6$^{th}$ largest sugar producer has over 75 sugar mills with annual production capacity of about 2.4 million tons during 1996-97. The contribution of Sindh with 27 sugar mills is recorded over 50% of the total sugar production. The majority of the mills in Pakistan use the Defecation-Remelt-Phosphitation (DRP; 24 mills), Defecation-Remelt-Carbonation (DRC; 21 mills) and Defecation-Remelt Carbonation and Sulphitation (DRCS; 11 mills) process. Seven of the 75 sugar mills in Pakistan also produce industrial alcohol from molasses, a by- product of sugar manufacturing process. These sugar industries also produce fly ash, which have been found to contain unburned carbon and reach as far as four-kilo meter area with the wind direction, threatening the community health of people living around, besides posing other aesthetic problems. The untreated wastewater, in many cases, finds its way to open surface drains causing serious threat to livestock, flora and fauna. One study showed that fly ash emitted from the chimneys contain particle size ranging from 38 ${\mu}{\textrm}{m}$ to 1000 ${\mu}{\textrm}{m}$. About 50 per cent of each fly ash samples were above 300 ${\mu}{\textrm}{m}$ in size and were mostly unburned Carbon particles, which produced 85% weight loss on burning in air atmosphere at 1000${\mu}{\textrm}{m}$. This fly ash (mostly carbon) was the main cause of many health and aesthetic problems in the sugar mill vicinity. The environmental challenge for the local sugar mills is associated with liquid waste gaseous emission and solid waste. This paper discusses various waste recycling technologies and practices in sugar industries of Pakistan. The application of EM technology and Biogas technology has proved very successful in reusing the sugar industry wastewater and mud, which otherwise were going waste.
