  • There has been so many research activities about robot soccer system in the many research fields, for example, intelligent control, communication, computer technology, sensor technology, image processing, mechatronics. Especially researchers research strategy for attacking in the field of strategy, and develop intelligent strategy. Then, soccer robots cannot defense completely and efficiently by using simple defense strategy. Therefore, intention extraction of attacker is needed for efficient defense. In this thesis, intention extractor of soccer robots is designed and developed based on FMMNN(Fuzzy Min-Max Neural networks ). First, intention for soccer robot system is defined, and intention extraction for soccer robot system is explained.. Next, FMMNN based intention extractor for soccer robot system is determined. FMMNN is one of the pattern classification method and have several advantages: on-line adaptation, short training time, soft decision. Therefore, FMMNN is suitable for soccer robot system having dynamic environment. Observer extracts attack intention of opponents by using this intention exactor, and this intention extractor is also used for analyzing strategy of opponent team. The capability of developed intention extractor is verified by simulation of 3 vs. 3 robot succor simulator. It was confirmed that the rates of intention extraction each experiment increase.

  • Recently, according to the increase of using the microwave equipments, the interests in effects on human body have been also increased. For example, there have been many researches on making the standard the specific absorbing ratio (SAR) caused by mobile phones. However, it is needed to study on the induced current on human body caused by HF(Hight Frequency) band which can deeply penetrate the human body. Especially, since the RFID systems are applied to the transportation card and the library, it is hooded to research on the effect on human body exposed to the radiated power from the RFID system. In this paper, we designed a cylindrical monopole antenna model of human body exposed to 13.56 MHz RFID system, which can model the induced current on human body. To verify the proposed equivalent antenna model, we compared the induced currents between human body and the equivalent antenna model.

  • This is case comments of several representative legal cases regarding self- determination right of patient. In a case in which an intoxicated patient attempted suicide refusing treatment, the Supreme Court ruled that the medical team's respect for the patient's decision was an act of malpractice, and that in particular medical situations (medical emergencies) the physician's duty to preserve life supersedes the patient's rights to autonomy. Afterwards, at the request of the patient's family, and considering the patient's condition (irrecoverable death stage, etc.) consistent with a persistent vegetative state, the Supreme Court deduced the patient's intention and decide to withdraw life-sustaining treatment. More recently, regarding patients who refuse blood transfusions or other necessary treatment due to religious beliefs, the Supreme Court established a standard of judgment that can be seen as conferring equal value to the physician's duty to respect patient autonomy and to preserve life. An empirical study of legal precedent with regard to cases in which the physician's duty to preserve life conflicts with the patient's autonomy, grounded in respect for human dignity, can reveal how the Court's perspective has reflected the role of the patient as a decision-making subject and ways of respecting autonomy in Korean society, and how the Court's stance has changed alongside changing societal beliefs. The Court has shifted from judging the right to life as the foremost value and prioritizing this over the patient's autonomy, to beginning to at least consider the patient's formally stated or deducible wishes when withholding or withdrawing treatment, and to considering exercises of self determination right based on religious belief or certain other justifications with informed refusal. This will have a substantial impact on medical community going forward, and provide implicit and explicit guidance for physicians who are practicing medicine within this environment.

  • The thermodynamic characteristics of a combined cycle applied with a topping cycle such as a trilateral cycle at relatively high temperatures and a bottoming cycle such as an organic Rankine cycle at relatively low temperatures have been theoretically investigated. This is an electric generation system used to recover the waste heat of the exhaust gas from a diesel engine used for the propulsion of a large ship. As a result, when the boundary temperature between the topping and the bottoming cycles increased, the system efficiencies of energy and exergy were simultaneously maximized because the total exergy destruction rate (${\sum}\dot{E}_d$) and exergy loss ($\dot{E}_{out2}$) decreased, respectively. In the case of a marine diesel engine, the waste heat recovery electric generation system can be utilized for additional propulsion power, and the propulsion efficiency was found to be improved by an average of 9.17 % according to the engine load variation, as compared to the case with only the base engine. In this case, the specific fuel consumption and specific $CO_2$ emission of the diesel engine were reduced by an average of 8.4% and 8.37%, respectively.

  • The Triangle Mesh Warping method is suggested and applied in coordinate transformation to world geodetic system in this study. The common points of Uiwang city are used to compare the transformation accuracy of the suggested methods with existing national coordinate transformation methods. As a result, the Triangle Mesh Warping method was satisfied with accuracy criteria for positioning on a map larger than scale 1/1,000 with smaller number of common points and without distortion modeling. Additionally, in case of Guri and Pyeongtaek city that established the World Geodetic System, the suggested method generates the result of transformation accuracy better than 5cm. Based on the test, it was found that the suggested method improves the problem of securing many common points and reduces the problem of mis-match between the transformed data of adjacent areas. Accordingly, for transformation of large-scale topographic map, cadastral map, GIS DB and serial cadastral map to the World Geodetic System, it is judged that the Triangle Mesh Warping would be a good method for economical efficiency and accuracy using by minimum common point.

  • The Detection Model is the model to find the result of a certain purpose using artificial intelligent, data mining, intelligent algorithms In Cyber Security, it usually uses to detect intrusion, malwares, cyber incident, and attacks etc. There are an amount of unlabeled data that are collected in a real environment such as security data. Since the most of data are not defined the class labels, it is difficult to know type of data. Therefore, the label determination process is required to detect and analysis with accuracy. In this paper, we proposed a KDFL(K-means and D-S Fusion based Labeling) method using D-S inference and k-means(unsupervised) algorithms to decide label of data records by fusion, and a detection model architecture using a proposed labeling method. A proposed method has shown better performance on detection rate, accuracy, F1-measure index than other methods. In addition, since it has shown the improved results in error rate, we have verified good performance of our proposed method.

  • Our society's modernization created many opportunities for us to need a private investigation service system. Variation of international environment due to joining in the OECD, opportunity of individual legal, collect evidence during judgement, prevention of damage criminal, security of business in company, free trade economy's system etc and don't need to enumerate how important of introduction of private investigation service system. In addition to there are lots of objection opinions, such as possibility of person's private life, invade of lawyer's area, confliction with investigation team, gap of wealth and poverty that make preponderance of information. So this research can be considerate from objective opinion, and can obtain conclusion just like below. First, private detective agencies that encroach on the individual rights will naturally deteriorate after the implementation of private investigation service system. Through this, the probability of civil rights encroachment will be lower, and for this to happen there needs to be a thorough maintenance of the system. Secondly, mutually beneficial solution should be found not by a conflict between two sides. Detective business sector should not cause social confusion from conflicts with other investigation organization such as police, or investigators, rather, it must get on the demand of the diversified citizen and maintain the diverse sector inter-cooperate right, and to do that law and institution must be made for the base. Thirdly, investigation used depending on the gap between wealth and poverty does not mean the actualization of the rights and interests of the citizen. If the duty of investigation sector is to find the evidence and collect or manufacture of the evidence, then the problems which the nation can't handle will be more enlarged and then finally end up with strengthening the capability of national public security demand.

  • Recently, our company has entered the modern knowledge company, government policy and regulation has a big influence on people's lives. Also, unlike in the past, I am hoping for administrative intervention as a problem peculiar to the environment, such as environmental housing problems, urban transportation problems, misuse problems, etc. and corporate pending issues. In this study, through the 10th year of the Seoul Special Citizen Judicial Police Force, if the local autonomy is a special envoy, it will try to present the correctness in the organization luck. As a measure to secure the nature of administrative action, the method of investigation was through the study of the execution process of administrative penalty and its result based on the statistical data of Seoul City. Therefore, we will analyze the process and operation of the 10-year organizational change of the Seoul Metropolitan Government's police force and examine how the police force of the people's livelihoods, which is a special investigation organization, is expanding its duties in order to strengthen the enforcement power of the administration. Also, we will make future-oriented suggestions to encourage the readjustment of the current relevant laws, such as the Ministry of Patriots and Veterans Affairs, and to actively accommodate the expected changes of the special law police organization in charge of the enforcement of the police system.

  • This study was conducted in an effort to identify the fluctuation of species according to space and time by collecting information on samples of Korean Sphingid moths housed in Korea. The number of Sphingidae moth species housed in Korea was found to be 53. As 48 species and 47 species were found in Gyeongsangnam-do and Gangwon-do, respectively, relatively diverse species were considered to be distributed in these areas. Comparatively, in Jeollabuk-do only 36 species were found, whereas in Chungcheongbuk-do and Jeju Island 39 species were found. The number of individual Sphingid moths surveyed in Korea was 21,414. With regard to the number of individuals per species, Ampelophaga rubiginosa was highest, at 2,483, followed by Theretra japonica (1,716), Callambulyx tatarinovii (1,457), Acosmeryx naga (1,340), Rhagastis mongoliana (1,191), Marumba sperchius (1,083), and Dolbina tancrei (1,072). By region, the largest number of individuals was surveyed in Gyeongsangnam-do (4,595), followed in order by Gangwon-do (3,648 individuals), Gyeonggi-do (3,011), Jeollanam-do (2,454), and Jeju Island (2,382). Over time, the highest numbers-in this case 9,498 individuals in 52 species-were identified after 2000. In the 1990s, there were 6,027 of 49 species identified; in 1980s, 4,332 individuals of 49 species were identified; and, in the 1970s, 937 individuals of 45 species were identified. It was confirmed that more species and individuals were identified as time passed. The appearance of Sphingid moths by month was found to be as relatively diverse, as they appeared from February to November. Overall, southern species, including M. saishiuana, Cephonodes hylas, Acosmeryx castanea, T. nessus, and T. clotho, which mainly inhabit Jeju Island and the southern part of Korea, have increased over time from the past to the present. Species inhabiting the middle or northern parts of the Korean Peninsula or the entire country of Korea, including Sphingulus mus, Ambulyx schauffelbergeri, and Mimas christophi, show decreases over time.

  • The slime, deposited in the bored pile due to falling soil particle, reduces the bearing capacity of bored pile and thus the stability of construction also decreases. The weight pendulum and iron have been used for estimating the slime thickness based on the subjective judgment and thus the previous method has a limitation of reliability. The objective of this paper is to suggest the method for estimating the slime thickness by using characteristics of electrical resistivity as scientific method. The temperature-compensation resistivity probe (TRP), which has a conical shape and the diameter of 35.7mm, is applied to the measurement of the electrical resistivity in the borehole during penetration. The field tests are carried out for estimating the slime thickness in the application site of bored pile. The slime thickness is calculated through the difference between excavation depth of borehole and measured data. Furthermore, the laboratory tests are also conducted for investigating effects of casing, time elapsing and relative density by using the specimen of slime. The laboratory test supporting the suggested method is reasonable for determining the slime depth. The paper suggests that the electrical resistivity method may be a useful method for detecting slime thickness and the method is expected to be applicable to various sites of bored piles.
