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.

The problem is that even though the cost of apartment buildings and general expenses are the same and similar tasks, there is a significant gap between them in quantity and quality. The apartment security guard needs more professional management in education and various reporting obligations. In particular, the reality of being away from the management and supervision of the National Police Agency, which is in charge of crime prevention and policing resources throughout the nation, is a task that needs to be improved quickly. Although the "security service" is a specialized area for protecting the lives and property of the people, it is managed and operated only in the category of apartment management, just because it is under the jurisdiction of the Ministry of Land, Infrastructure and Transport. This should be integrated into one cost-related law, such as the "Cost Business Act," for management and operation. Although the regulations concerning security guards under the "Joint Housing Management Act" are very limited, they should start discussing the integrated management of apartment security guards and general security guards in view of improvement of their treatment. The most realistic method would be to hire a new general security officer with a security law as a security guard in an apartment building.

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.

This paper presents a mixed linear and integer goal programming (GP) model to aid in strategic planning and scheduling of guard soldiers. The proposed model is a general-purpose model, hence can be used to produce an optimal schedule with respect to any user-provided combination of guard post objectives and soldier preferences. We extensively test the usefulness of the model on a real-life dataset from a guard post in the ROK Army with using three objectives set by the guard post and three preferences provided by individual solders. Numerical results and analysis from these experiments show that the proposed guard scheduling model efficiently as well as effectively generates an optimal guard schedule and can also be used for an optimal revision of any existing schedule. In summary, these illustrate that the proposed model can be practically used for optimal planning and scheduling of guard soldiers in guard posts.

This study aimed to find a proper size of Korea Coast Guard. To attain this goal, this study constructed an experimental standard quota model then calculated the proper number of employees of Korea Coast Guard, The findings of the analysis can be summarized as follows: The formula of the model constructed through reviewing related literature is as folllows: Y(manpowers) = constant + (B $\times$ the number of crimes committed) + (B $\times$ the expenditure in the general account) + (B $\times$ the number of Korea Coast Guard vessels). The proper employment size of Korea Coast Guard calculated using the model was 7,369.

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.
