The tensions between the U.S and China, which form the two pillars of the G2 era, seem to have persisted even after the Trump administration inaugurated. The strong confrontation between the two in recent foreign security issues may drive to develop an inadvertent military conflict, and it is high likely to occur in the maritime are. The purpose of this study is not only to analyze the balance of modernized naval forces in the PLAN through naval strategy changes and weapons system modernization trend, but also to predict the impact of the geographical proximity difference on the balance of naval forces in the disputed areas. It examined the impact of distance and geography on naval power by assessing the modernization pattern of the PLAN and capabilities in the context of two scenarios at different distances from China by 2020: one centered on Taiwan and the other on the Spratly Islands. The PLAN's strategy had impact on operational concept and forces construction. First, from the viewpoint of operation operational concept, it can be seen that the passive defense is changing into active defense. Second, in terms of power construction, it can threaten the surface and submarines of U.S power from a distance. And they generated follow three features; The ocean is not the focus of Chinese submarines, Horizontal and vertical expansion of Chinese naval vessels, The improvement of the suppression ability as the Chinese naval modernization ratio increases. The strength of the PLAN is dominant over the U.S in terms of reserves, and it can complement the qualitative deterioration by utilizing nearby bases in the vicinity of the mainland, such as the Taiwan Strait. However, due to the shortage of aircraft carriers, there is a possibility that it will take some time to secure the advantage of air and ocean in the amphibious operation. Therefore, as the dispute is prolonged, China may fail to achieve its original goal. In addition, the lack of cutting edge Commanding Ships may bring to weaken the C2 capabilities. At results, it is expected that PLAN will not be able to have a superiority in the short term due to lagging behind U.S advanced technology. Nevertheless, PLAN has strengthened its naval power through modernization sufficiently and it is highly likely to use force. Especially, it is more likely in the region where the naval power operation like the Taiwan Strait is possible with the almost equality to that of the United States. China will continue to use its naval forces to achieve a rapid and decisive victory over U.S in the close area from the land.

The legal integration in the European Union that seeks a unified system in consumer disputes and the German Consumer Dispute Mediation Act based on this pursues the procedural fairness of consumer disputes and the equality of results. The role and legal status of the dispute mediator, who plays a very important role in this process, and the stable operation of the dispute resolution system and the guarantee of reasonable results through the guarantee of fairness and independence are very important values. In particular, the dispute mediator under the Act is conceptually different from the existing mediator or mediator, and through this distinction, the duties and contents of the dispute mediator are also distinguished. For this reason, the qualifications of dispute mediators that affect the outcome of dispute mediation are strictly stipulated. There have been some criticisms of this strictness, and such strictness is also seen as an excessive limitation. However, these standards can be understood as one of the efforts to make the dispute mediation procedure more systematic and to operate objectively in accordance with laws and procedures. In addition, in relation to the issue of independence and impartiality of the dispute mediator, the status of the dispute mediator is guaranteed in various aspects. In economic terms, it is not influenced by external factors, and furthermore, in order to guarantee job stability, the results of job security and dispute resolution are not linked. By examining the appropriate level of discipline for these dispute mediators, we expect the developmental growth of the consumer dispute resolution system under our Act.

The 'digital divide' is regarded as a latent dysfunction that impedes the intrinsic role of information to contribute to social equality. Therefore, it has drawn great attention inside and outside of academia. The growing interest in the digital divide has been driven by the realization that it can create a serious crisis that threatens a social system compounded by existing economic, social, and cultural inequality, rather than being limited to an uneven distribution of information. In this paper (1) studies on the digital divide published since 1970 are reviewed, (2) studies noteworthy of discussion are selected to assess their academic significance, and (3) the tasks and prospects of digital divide research are explored. Although meaningful achievements have been amassed through continuous interest and efforts of the academic community, two limitations are raised; the gap between pure research and policy research that hinders the working of synthetic imagination, and the intellectual lag falling behind a rapidly changing society. In addition, it is suggested that the operation, curation, and augmentation gaps would emerge as new agenda for digital divide research in the intelligent information age.

u-T (ubiquitous transportation) environment can be envisioned as an advanced version of ITS environment and be expected to provide more advanced transportation service in a ubiquitous manner. As a basic necessity to measure traffic flow in both environments, a flow estimation method was proposed. Flows have been measured in existing ITS and in a new u-T environments and some differences were investigated using simulation technique. In the interrupted traffic situation, the flow rate of u-T is 3.58% higher than that in ITS environment. Both MARE and MAE, which were used as measure of effectiveness, in u-T were better since the results are 31.4% and 31.1% lower than in ITS, respectively. Besides the equality coefficient in u-T was 1.9% higher than that in ITS. Such being the case, the flow rate measured in u-T using U-TSN is more reliable and can be expected to be successfully used for transportation system design or traffic operation areas.

In order to investigate on the field performance of 3.5PS power tiller and to obtain the optimum using conditions of it, this experiment has been carried on the plowing operation, the rotary harrowing operation and the ridging operation that compared 3.5PS power tiller(KC-450) with the existing 5PS(DT-40) and 8PS(DT-85) power tiller. It has been performed at Suck Jung-Dong, Ansung Country, from March to October in 1980. The results of this field test were obtained as follows; 1. The plowing performance of KC-450 tiller was found to be 125min/10a that was lower than that of DT-85 tiller by 26min/10a in the effective plowing speed 0.9m/sec. 2. The field efficiency of KC-450 tiller was the highest among the power tillers as to be 82 persent that was higher than that of DT-85 tiller by 5 persent in the effective plowing speed 1m/sec. 3. The rotary harrowing performances of DT-40 tiller and DT-85 tiller were higher than that of KC-450 tiller in the rotary harrowing operation of the same speed, and the field efficiency of KC-450 tiller and DT-40 tiller were higher than that of DT-85 tiller in the rotary harrowing operation. 4. The ridging Performance of testing power tillers were nearly equality in the ridging operation of the same speed, and the field efficiency of testing tillers were higher KC-450 tiller than DT-40 tiller, DT-40 tiller than DT-85 tiller. 5. The work performance of power tiller increased with increase in the size of field area. Work performance and field efficiency of KC-450 tiller were higher than other tillers below 8a in field size 6. DT -85 tiller was more useful in deep plowing depth. But below 8a in field size KC-450 tiller was more easily operated and its field efficiency was higher 7. KC-450 tiller should be more useful to operate in the small size field or in the small scale farming and for the cultivation of vegetables, gardening plants, medicinal herb and tobacco plants, or for the cultivation in vinyl house.

To explore the device to allow the marriage immigrants' family to take jobs in our country, the social and economic environments that they face are investigated and analyzed through literature survey and field inquiry. The principal motive of the marriage to Korean is economic problem. But their actual economic conditions are inferior, and other legal problems, such as getting jobs and remitting money to their home country, drive them to unstable status. The present hiring policy is applied only to foreign workers with no domestic relations(E-9), hence the marriage immigrants are excluded from the domestic employment. To make institutional devices for giving them the employment opportunity, the modification of the existing laws are proposed. For examples, the 'Act on employment of foreign workers' can be revised to permit immigrant's relatives to get jobs, and 'Immigration control law' can be amended to guarantee legal qualification for taking jobs. It is desirable that the overall control be made by the Prime Minister's Office, and operation as well as surveillance be performed by the Ministry of Gender Equality and Family (MGEF) and the Ministry of Employment and Labor (MEL).

This research suggested the traffic signal calculation model of active transit signal priority using a shockwave model. Using this signal priority timing optimization model, the shockwave area is computed under the condition of Early Green and Green Extension among active transit signal priority techniques. This study suggested the speed estimation method of backward shockwave using average travel time and intersection passing time. A shockwave area change is calculated according to signal timing change of transit signal priority. Moreover, this signal timing calculation model could determine the optimal signal priority timings to minimize intersection delay of general vehicles. A micro simulation analysis using VISSIM and its user application model ComInterface was applied. This study checked that this model could calculate the signal timings to minimize intersection delay considering saturation condition of traffic flow. In case studies using an isolated intersection, this study checked that this model could improve general vehicle delay of more over ten percentage as compared with equality reduction strategy of non-priority phases. Recently, transit priority facilities are spreading such as tram, BRT and median bus lane in Korea. This research has an important significance in that the proposed priority model is a new methodology that improve operation efficiency of signal intersection.

Registered security guards carry out police duties as civilian police who are in charge of security service, and so they have a two-fold status: a civilian in terms of a social standing and a policeman in the way that they execute the authority of security. The problem caused by this legal position is that their legal rights and obligation can be unclear in the task-action and working relationship. This paper attempts to study their functions, rights, and legal duties through the interpretation of the related positive law so as to reveal the problems that may spring from this ambiguous status of registered security guards. This endeavor illuminates their legal status specified in the positive law in and around the Act on the police assigned for special guard, observing their functions and the legal duties in the pursuit of their tasks, and ending up pointing out the problems of the positive law. As a result of research work, the most significant problems, even if multifarious, are the avoidance of the state reparation in the responsibility for the illegal behavior in connection with their operation; the unconstitutionality of the disciplinary punishment regulation originated from the entrust with full powers; the imperfection of the rules about the cooperative ties with the police; the possibility of human rights abuse caused by the ban on the labor dispute; the equality problems from the dual pay system; and the inadequacy of the codes about the recruitment qualification and method. This research is intended to help achieve the purpose of the security of national critical facilities through the smooth execute of duties as well as the protection of the guards' rights. Besides, the key focuses posed in this paper are worthy of being developed more accurately through the following researches.
