The problem of mathematical model for an unknown system by measureing its input-output data pairs is generally referred to as state estimates. The state estimation problem is often of importance in its own right since we may want to know the value of the states. For instance, in navigation, we may take noisy positional fixes using satelite or radar navigation, and the estimator can use these measurements to provide accurate estimates of current position, hedaing, and velocity. And the state estimates can also be used for control purposes. Then it is very important to know the state of plant. In this paper, the theory of the minimization of a loss function was used to design the fuzzy system. Here, the used teory is Least Square Esimation method. This parametrization has the Linear in the parameters charcteristic that allows standard parameter estimation technique to be used to estimate the parameters of the fuzzy system. The combination of the fuzzy system and the estimation m thod then performs as a nonlinear estimator. If several fuzzy label are defined for the input variables at the antecedent part, the fuzzy system then behaves as a collection of nonlinear estimators where different regions of rules have different parameters. In simulation results, the fuzzy model controlled a difference in the structure between the actual plant and the fuzzy estimator. It is also proved that the fuzzy system is equivalent to its transformed system. therefore we was able to get the state space equation of system with the estimated paramater.

Surely fuel economy(F.E.) label is needed to meet consumer's right to know. Korea has developed and adopted F.E. correction equation similar to the feeling, because consumer complain about F.E. label higher than they feel. Recently, through continuous research and development high-efficiency & performance green car like HEV, PHEV and EV are being sold. In this situation, it is needed to know whether the current equation can reflect a part of their improved technic or not. In this paper, to review current equation through test using hybrid vehicles on 5-cycle SOC, correction equation and F.E were discussed. The result show HEV didn't meet the SOC error standard on US06. Also, HEV has bigger F.E. difference between FTP-75 and 5-cycle than conventional vehicles. However, the correction equation that include HEV almost same with current one.

Botulinum toxin type A is widely used for anti-wrinkling therapy, and correction of the square face. The toxin ultimately prevent the release of membrane-bound acetylcholine at the neuromuscular junction of striated muscles and thus produce chemical denervation and paralysis of the muscles. Our purpose of study is to know if application of botulinum toxin type A on calf reduction is effective, how much dosage is effective, and what are the possible complications. We reviewed data of 30 consecutive patients subjected to calf reduction in Dong-A University Hospital from February 2003 to April 2003. We injected normal saline 2cc on both calves region in 15 control group patients, and the other patients was divided 3 group. Group 1, Group 2, Group 3 was injected 50U, 100U, 150U botulinum toxin A on each calf region and followed up for 6 month. Maximal circumference of calf was not changed in the control group but an average of 0.7 cm reduction was noted in group 1, average 1.34 cm(right calf) and 1.26cm(left calf) in group 2, average 1.44cm(right calf) and 1.58cm(left calf) in group 3. Maximal area of calf was not changed in the control group but average reduction of 12.5%(right calf) and 12.7%(left calf) was obtained in group 1, average 19.4% (right calf) and 19.9%(left calf) in group 2, average 24.8%(right calf) and 21.07%(left calf) in group 3, as measured on CAT scan. Total fat amount and fat amount in the lower extremity was no change in all the groups, but lean body mass was decreased average 1.27%(right calf) and 1.15%(left calf) in group 1, average 3.47%(right calf) and 2.98%(left calf) in group 2, average 3.58%(right calf) and 3.95%(left calf) in group 3. Photography of the preoperative and postoperative 6 month state revealed higher satisfaction in Group 2, 3 compared to Group 1. Use of botulinum toxin type A in calf reduction is a very simple, safe, non-invasive method and effective in terms of calf contouring rather than reduction of calf circumference.

As the citizens' life and body are the object of medical practice, it should ultimately protect the citizens' right of health. For this reason, medical practice possesses characteristics of non-profit and public and such special characteristics caused heavy regulations in the medical industry as exemplified by medical advertisements. For advancement of market economy, the government has been moving toward relaxing regulations in the medical industry and this trend can be shown in medical advertisements. Moreover, as a type of commercial advertisements, medical practitioners should be able to express their freedom of expression and freedom to occupation. From the perspective of patients who are medical consumers, they need access to information to locate appropriate medical practitioners and institutions for their symptoms. Therefore, medical advertisements can help realize the patients' right to know. This study will first analyze the general theories behind the necessity of medical advertisements and details of regulations, then analyze the issues from the cases of the supreme court and the constitutional court that are related to dental medical advertisements.

With the advances of digital scanning technology in dentistry, the interests in facial scanning in orthodontics have increased. There are many different manufacturers of facial scanners marketing to the dental practice. How do you know which one will work best for you? What questions should you be asking? We suggest a clinical guideline which may help you make an informed decision when choosing facial scanners. The characteristics of 7 facial scanners were discussed in this article. Here are some considerations for choosing a facial scanner. *Accuracy: For facial scanners to be of real value, having an appropriate camera resolution is necessary to achieve more accurate facial image representation. For orthodontic application, the scanner must create an accurate representation of an entire face. *Ease of Use: Scanner-related issues that impact their ease of use include type of light; scan type; scan time; file type generated by the scanner; unit size and foot print; and acceptance of scans by third-party providers. *Cost: Most of the expenses associated with facial scanning involve the fixed cost of purchase and maintenance. Other expenses include technical support, warranty costs, transmission fees, and supply costs. This article suggests a clinical guideline to make the right choice for facial scanner in orthodontics.

This study is to enforce to ready basic data of effective dental education program and no smoking and no drinking program for high school students who do smoking and drinking, executed investigation by own recording way using smoking and questionnaire consisted of actual conditions and caries prevention awareness and dental health knowledge degree of drinking to some man high school. Analyzes result that total 487 people respond in SPSS WIN 13.0 programs and got following sequence. Result of this study is as following. 1. Mans high school students had more students who do not than a drinking student and main current received most soju. Third-year student appeared by thing which receive a lot of soju than 1 or 2 class student but different other difference was not seen by class. 2. Mans high school students had more students who do not than a smoking student and a student who smoke more than 3 years was the most. I can know was old since third-year student smokes than 1 or 2 class student. 3. It was not difference that keep in mind by drinking, smoking availability although there were many students who recognize that all of the on-time dental medical examination, sugar intake limitation, fluorine inclusion toothpaste, teeth fluorine application are seldom effective on caries prevention. 4. Recognized that right brushing is effective relatively on caries prevention. I was shown difference that recognized that righter brushing is effective on bad tooth courtesy call than a student who a student who do not smoke does, and keeps in mind according to smoking availability ($x^2$=6.78, p<0.05). 5. I knew best about question of 'A caries may not treat if is painless' among that question ask knowledge for a caries, and appeared by thing which do not know best about question of 'Know that method that supply fluorine in water'. 6. A student who do not drink general dental know-how for a caries was high knowledge degree for a caries than a drunk student but it was no difference that keep in mind by drinking availability. Also, a student who do not smoke by smoking availability was high knowledge degree for a caries than a done student but difference that keep in mind statistically was not seen. 7. It was no difference that keep in mind by drinking availability, but a student who do not smoke by smoking availability was high relation knowledge degree with food and a caries than a smoked student, and I was shown difference that keep in mind according to smoking availability(t=-2.03, p<0.05). 8. Awareness and synthetic estimation degree of knowledge degree a student who do not smoke than a smoked student mouth knowledge degree high, and I was shown difference that keep in mind according to smoking availability(t=-2.03, p<0.05). When see as result such as singularity, family, school, all social institutions may have to help by national business coming and try so that can become national business based on special know-how for development of effective and epoch-making education program as quickly as possible.
