We present a new approach to the analysis of mobile cellular communication systems under the environment of mixed platforms adopting a guard channel scheme. We assume general cell residence time distributions according to platform-types. Our system model is based on a heterogeneous M/G/c loss system with customer-dependent guard channels, where heterogeneous customers with different service time distributions have different numbers of their own guard channels. We develop the general formula of steady state probabilities for the heterogeneous M/G/c loss system with customer-dependent guard channels. The mean channel occupancy times of new and handoff calls are rigorously derived under a general setting. Finally, our numerical results show that the blocking probability and the forced termination probability are sensitive to the cell residence time distributions.

China National People's Congress has passed the bill to combine the Marine Law Enforcement into "State Oceanic Administration People's Republic of China". This bill was intended to resolve the overlapping jurisdiction and disputes caused in ocean territory in nearby countries. The purpose of reorganizing the administration was to combine the dispersed organization into one group. This new big administration was basically organized to increase the power of China marine state on the long-term. The reorganization plan is to group General Administration of Customs, China Marine Surveillance, Fisheries Law Enforcement Command, and Border Control Department into one State Oceanic Administration. The new state Oceanic Administration carries the authority to protect rights and enforce the marine law supported by Public Security Bureau. Korea Coast Guard has been cooperating with China Marine Surveillance since 1998 when the first pact was made. The next step expanded to General Administration of Customs. Currently working with Regional Maritime Law Enforcement organizations dealing mostly with illegal Chinese fishing boats and IEODO conflict. In order to solve the problems we face today is to observe the process of the New China Coast Guard administration, analysing the effects that could be caused by the change and to keep close cooperation between the new administrations.

공동주택경비와 일반경비는 동종 유사한 업무임에도 불구하고 이원적(二元的) 운영과 관리가 이루어지고 있다. 공동주택경비원도 교육에 있어서나 각종 신고의무 등에서 보다 전문적 관리가 필요하다. 특히 민간부문에서 경찰업무의 하나인 경비업무를 하고 있음에도 불구하고 국가 전반의 범죄예방과 치안자원의 상시관리를 담당하고 있는 경찰청의 관리 감독에서 벗어나 있는 현실은 하루속히 개선되어야 한다. '경비업무'는 국민의 생명과 재산을 보호하는 전문적 영역임에도 불구하고 '공동주택관리업무'가 국토교통부 소관업무라는 이유만으로 '공동주택의 관리'라는 범주에서만 관리 운영되고 있다. 이를 "경비업법"으로 통합하여 관리 운영하여야 한다. 비록 "공동주택관리법"상 경비원과 관련된 규정은 지극히 제한적이지만, 주택경비원의 처우개선 관점에서 공동주택경비원과 일반경비원의 통합관리에 관한 논의를 시작하여, "경비업법" 개정 및 "공동주택관리법"상 준용 규정 신설, 경비업법의 확장해석을 통한 아파트 경비업무 공백 방지, 직무중심의 전문교육 법제화의 방식으로 접근하여야 한다.

Our society witnesses the rapid progress in the areas of politics, economy, society and culture in the process of national modernization since 1960s, which in turn as a reverse function gets to contract a societic pathology, totally lowering the security level of citizens' lives owing to various violent crimes like hostage commotions and murders with rifles and deadly weapons. what is the main reason for that? That may be partly because the chief police force concentrates on the current situation resulting in the vacuum of the public peace. However, the main reason is that the police fall short of man-power and equipments even if the whole police power were put to use in preventing and quelling the crimes. That is true not only of Korea but also of the advanced countries like the U.S.A., England and Japan. We realize that these advanced countries have higher level of security in every individual's life and property than Korea because their progress of the private guard systems can fill in a vacuum of the shortage of the police power, Therefore, we should without delay internationalize our private guard systems expecting the widely opening of the guard service markets in the age of Uruguay Round. To do this, we need to change our ideas for fostering the policy of the private guard from passive defense ideas into positive aggressive ones. Our police should urgently set up a plan to pursue the orientation of vision that we should dispatch our private guards overseas before foreign guards rush into our markets. Accordingly it goes without saying that the private guard group should distinguish their services from the public services initiating their own theory and strategy of private guard services and also readjust themselves between the public duties and the private services with the study of minimizing the reverse function of the private guard systems. The history criminal justice has always shown that the criminal system progressed at the initiative of the civil factor in case its demand and supply do not make both ends meet. Nevertheless, in the process the power of the government never weakens, rather it is built up in general. In conclusion, the necessity of the build-up of the private guard services must duly be acknowledged by the police as well as by the business which has its unique sphere within the criminal justice instead of as the suplemtary services of the simple the police power on the long-term basis. The purpose of the private guard services can be largely classified into the two categories; first it means the function to prevent the crimes against the citizens and secondly to enhance the national interest as an increasing mammoth business with a worldly competition capacity. The police has an absolute responsibility that they should protect the modem public in general from feeling the crisis of the personal threat, tension, anxiety and nervousness. In short, if we develop the complete private guard system to guarantee the societic atmosphere for all citizens, keep the public peace, and protect all citizens' lives and properties, we will sure enjoy a beautiful land, a wholesome society and a happy life in goodharmony of law and order.

Objectives: The aim of this study was to investigate the influencing factors on oral and maxillofacial trauma prevention education experience of students majoring in physical education. Methods: A self-reported questionnaire was filled out by 268 students majoring in physical education in Busan. All statistical analyses were performed using SPSS 21.0. The questionnaire consisted of general characteristics(4 questions), TMJ symptoms(9 questions), oral habit(8 questions), and mouth guard awareness(5 questions). The questionnaire was carried out by 5 Likert scale. Higher points of Likert scale showed the negative tendency except the mouth guard awareness. The higher points of mouth guard awareness showed the positive tendency to use the mouth guard. Results: Male students had higher scores of 2.75 points in bad oral habit than the female students(p<0.05). Female students higher score of 1.30 points in mouth guard awareness than male students(p<0.05). TMJ symptoms experience in oral and maxillofacial trauma was 3.15 points which was higher than the prevention education experience without maxillofacial trauma(p<0.001). TMJ symptoms and Mouth guard awareness showed 2.71(p<0.01) and 1.20 points(p<0.001) respectively in students with maxillofacial trauma prevention education experience. These score were higher than those without education experience of trauma prevention education experience. The influencing factors on trauma prevention education experience are mouth guard awareness(p<0.001), oral habits(p<0.01), and temporomandibular joint symptom(p<0.01). Conclusions: The necessity of mouth guards should be emphasized to prevent the serious oral trauma. It is very important to establish the rule for mouth guard use in sports activities. Therefore, oral and maxillofacial trauma prevention education program is needed.
