The purpose of this study is to investigate the relations between marital status incompatibility and the ways of dealing with marital conflict. Research was conducted by interview using questionnaire on 177 employed wives. Statistics used for data analysis were frequency distribution, percentage, t-test, chi-square test. 1) In resolving marital conflict four types of method are appeared, namely constructive method, passive method, evasion and physical violence. 2) Only physical violence of husband-to-wife of the four methods is related to status in-compatibility. That is the incidence rate of physical violence of husband-to-wife in incompatible couples is higher than that of compatible couples in conflict situations. 3) In case the wife's occupational status is high relative to her husband the incidence rate of physical violence of husband-to-wife is extremely high, but is significantly low in couples which are compatible in this status. 4) In case wife's status advance ent is controlled, there is significant relationship between status incompatibility and the method of conflict resolution by husband whose wife is status striver.

In this paper, three-dimensional optimal evasive maneuver patterns for air-to-surface attack missiles against proportionally navigated anti-air defense missiles were investigated. An interception error of the defense missile is produced by an evasive maneuver of the attack missile. It is assumed that the defense missiles are continuously launched during the flight of attack missile. The performance index to be minimized is then defined as the negative square integral of the interception errors. The direct parameter optimization technique based on SQP and a co-evolution method based on the augmented Lagrangian formulation are adopted to get the attack missile's optimal evasive maneuver patterns. The overall shape of the resultant optimal evasive maneuver is represented as a deformed barrel-roll.

일상생활 속에 익숙하게 자리 잡은지 오래인 모바일 폰은 이미 고유의 기능인 음성통화와 문자메시지에 대한 서비스가 포화상태 이르러 새로운 수익 창출산업으로 무선인터넷서비스가 각광받고 있는 실정이나, 초기 사용자들에게 부정적인 기대 불일치 경험을 누적시켜 소극적인 사용이나, 사용회피를 유도하는 등 아직까진 기대 이하의 성적을 거두고 있는 실정이다. 예상을 뛰어넘는 과도한 요금에 놀라 이후 무선인터넷 사용을 꺼리게 된 경험이나, 청소년들의 무분별한 무선인터넷 사용에 따른 사고 등 폐해들에 대한 기사 등은 이미 낯설거나 놀라운 뉴스가 아니며, 이러한 직 간접경험들로 인해 아예 무선인터넷을 경험해보고자 시도조차 하지 않는 잠재고객 또한 많은 것이 사실이다. 본 논문에선 설문과 실험을 통해 현재 모바일 사용자들의 무선인터넷 서비스에 대한 기대, 사용 패턴, 만족도 및 바램과 요금체계에 대한 이해도 등을 조사하고, ‘불확실성 회피성향’이 사용회피에 미치는 역효과를 증명하여, 요금체계와 관련한 서비스업계의 개선 방향 제시에 연구목적을 가진다.

As a part of environmental pollution prevention and resources recycling, the regeneration of waste tire has been largely contributed to national industry. But, the worker has been evaded this regeneration process by reason of the best mischievous process condition among 3D industries. So, the first, the process condition of regenerating waste tire was analyzed. The second, the equipment or system was developed for the improvement of working strength and environment. The last, researchers intend to solve these problems

Minors' law evasion is getting serious. Some of them make a fake ID card or use a stolen ID card illegally. They are illegally used for buying alcohol, cigarette, bond or going to club, pub, motel and so on. On the latest News, there was a case that teens rented a car with a driver licence without checking and had severe car accident. Like this case, car rental service was fined and suspended from business because they did not figure out ID card's counterfeit or modification. Thus, this study investigates the detecting method about the ID card(including a driver license) counterfeit, modification or illegal use. The server has a database of 17~19's minors one fingerprint and services whether the visitor is adult true or not. The method will be usable and economical for business. Then, it was compared and analyzed with methods already in use in business.

A differential game theory based approach is used to develop an automated maneuver generation algorithm for Within Visual Range (WVR) air-to-air combat of unmanned combat aerial vehicles (UCAVs). The algorithm follows hierarchical decisionmaking structure and performs scoring function matrix calculation based on differential game theory to find the optimal maneuvers against dynamic and challenging combat situation. The score, implying how much air superiority the UCAV has, is computed from the predicted relative geometry, relative distance and velocity of two aircrafts. Security strategy is applied at the decision-making step. Additionally, a barrier function is implemented to keep the airplanes above the altitude lower bound. To shorten the simulation time to make the algorithm more real-time, a moving horizon method is implemented. An F-16 pseudo 6-DOF model is used for realistic simulation. The combat maneuver generation algorithm is verified through three dimensional simulations.

A multi axis whetstone polishing system, which uses the flow system of the stone polishing machine head, has been developed. The test results show that the defect by line contact polishing does not occur in both ends of the stone and that it came to trim smoothly. In terms of the surface roughness, the corresponding index was decreased by 3.6 times, improving the polishing effect greatly. It decreased significantly the dust and noise with the wet polishing. The factors of the duty evasion at production site can thus be solved with the work environment improvement against the polishing process of the stone industry and work intensive reduction.

Corporation had been made by important action rule of business ethics that observes legal standard that is prescribed in each class of administration activity. But it does not keep ethicality of corporation action that conforms law. Law can not include all parts of business ethics because it is forcing essential class for public order preservation and public welfare in right. Moreover, partial corporations are doing to justify unethical action of other evasion of taxes, consultation, manufacturing etc. with legal basis meaning abusing legal standard. For these reason, Insistence that is in point of legal standard and ethical standard is not different each other that is in equal viewpoint is brought.
