Jeju Special Self-Government Province adopted an autonomous police system for the first time since 60 years in Korean police. The purpose of autonomous police system is to offer a police service to be suitable in regional conditions. But Jeju autonomous police system for nearly one year after adoption is criticized to be established on the ground of political reason but not local decentralization. Actually Jeju autonomous police has not a clear cut jurisdiction and operation scope because of the jurisdiction duplication between national and autonomous police. The original task is confined on environment and sightseeing so on given to administration police for local self-government. So criminal investigation authority on general crimes is not to Jeuju autonomous police on account of special judicial police. First, it is the structural rationalization of Jeju autonomous police system. It speaks that Jeju provincial police bureau and police station have to be as national police institution, on the other hand, patrol district station and police box have to be as autonomous police institution. Of course, functional division has to be followed. National police performs managing all the assembly and demonstration by the management law on assembly and demonstration including the suppression against any large scale demonstration and disturbance, also the investigation on serious crimes just as international crimes and broaden area crimes including all the felony. Together national police performs the duty concerned to all the foreign affairs and national securities in along with the investigation on traffic accidents. On the other hand, autonomous police performs the function for citizen's life safety as crime prevention and the enforcement on the violation against police operation law, together the traffic management and the regulation on traffic violations. and the investigation on minor crime as simple violence or petty larceny including the management on local big events. Second, the budgetary of autonomous police is rationalized by the share of budgeting between Korean government and Jeju special self-government province. Third, urgent arrest authority on general crime and the rights of claims for the summary trial on minor crimes are given to autonomous police. Of course, this problem is resolved naturally in case of giving the investigation rights to autonomous police on minor crimes.

The air market in Asia has already entered upon the age of limitless competition. It means a very important moment in Asia air market. Each Asian country thus has put a lot of effort into a development plan and support to their hub airport. In order to achieve such a plan, first of all we should build closer cooperation system between the two countries Japan and Korea. The Korea and Japan are very fast growing in the northeast countries within the global air transport market. Air passenger and cargo traffic volumes between Korea and Japan have increased dramatically, since the 1990s. In response to such a trend, both countries have opened new airports and expanded existing facilities in the hopes of laying claims to the main international hub airport in Asia. Apart from the trend, air transportation between Korea and Japan's metropolitan areas is the only transportation in substance, even if they are located very closely in geographical position. The air transportation between the two countries shows that it is necessary to get fast and more convenient because of the economic and cultural interchange and exchange concentrated on the metropolitan areas, and that will promote the economic growth of Korea and Japan. However, within the air transportation industry field, there have no sufficient seats/slots to supply the air demand from the capital cities of each country, as well as no counterplan for some problems regarding capacityand sustain ability of metropolitan airports. Thus, it is necessary for us to consider in all aspects and solve them to improve air transportation between Korea and Japan. This paper is to try to demonstrate this matter and from all angles, that is, in legal and political aspects, facilities and given environmental conditions and cooperation between Korea and Japan. I think that it is indeed a great necessary and convenient for many Korean and Japanese tourists to conclude a new 'Open Sky Agreement' between Japan and Korea in order to the prepare the increase of the shuttle flight between Haneda-Gimpo and opening of air route newly for shuttle flight between Haneda and Cheongju as well as opening of air route for shuttle flight between Haneda-Shanghai Hongqiao International Airport and Beijing International Airport for the 2008 Beijing Olympic Games. Furthermore it is a great desirable thing for us to conclude a new 'Open Sky Agreement' in cooperation reciprocally among the Japan, China and Korea for opening the new air route by the shuttle flight.

This Study puts the purpose to explicate the regionalities of land-lease farming by a comparative analisis of the five case study areas in Kungpook Province as the agricultural space system of Teagu metropolitan city. For the regional comparative analysis the province was divided into the three zones with the distance from the central city(Teagu): urban fringes, intermediate and remote zone, and then subdivided into the five regions by farming systems : horticulture, rice-farming, and dry-field farming. The data were collected from 77 land-leasing farmers by questionnaire and interview with farm managers in 5 sample villages representing the regionalities of the above five regions respectively. In spite of relatively restricted scope of the research areas, the analytical results appear remarkable regional differences in the characteristics of land-lease farming within a single agricultural space system. In the final analysis the regionalities of the five land-lease farming regions could be described respectively as follows. (1) Koryong-Gun in the inner urban fringe zone : The developing land-lease farming region of commercialized suburban horticulture with medium scale. (2) Songju-Gun in the outer urban fringe zone : The developing land-lease farming region of highly commercialized horticulture with large scale. (3) Uisong-Gun in the intermediate zone : The stagnated land-lease farming region of commercialized rice-farming with large scale. (4) Yongil-Gun in the intermediate zone : The stagnated land-lease farming region of commercializing dry-field farming with medium scale. (5) Ponghwa-Gun in the remote zone : The stagnated and delayed region in commercializing of intermountain dry-field land-lease farming with small scale. These varied regionalities resulted from the diverse spatiality as a complex of spatial orders and localities. The spatial orders in this study are frequently recognizable as a form of distance-decay, and the locality of a region is determined mostly by the its peculiarity of physical and population conditions. In the comparative analysis of the regionalities the degree of commercialization of a region is a most comprehensive and useful frame of reference because it reflects the degree of development of capitalist land-lease farming. Finally these apparent regional differentiations of land-lease farming within a agricultural space system raise the problem of impracticality of the existing uniform logic on the land-lease farming such as "large scale farms share larger part of leased farmland." This problem suggests the urgent need of reappraisal of many aspatial logics and theories on the land-lease farming.

Temporal and spatial distributions of salinity, temperature, dissolved oxygen (DO), and turbidity were investigated at seven sites in the upper regions of brackish Lake Sihwa with a limited water exchange, from March to October 2005. During the study period, salinity and temperature varied $0.1{\sim}29.9\;psu$ and $4.7{\sim}28.1^{\circ}C$, respectively, depending on seasons and sites sampled. A distinct halocline profile showing the maximum density gradient (difference over $20\;psu\;m^{-1}$ between surface and bottom layers) was observed during the rainy season, due to the decrease of salinity in surface layers by freshwater inflow. This result implies that rainfall event is the important factor forming the halocline. On the other hand, the depth and location of haloeline varied with the amount of seawater through the sluice gates and the operation systems (inflow or outflow). High DO (over 300% saturation) was observed at surface layer above the halocline in April when red tide occurred, whereas low DO (below 20% saturation) was at the bottom layer below the halocline in the rainy season. Turbidity ranged $1.5{\sim}80.3\;NTU$ showing the maximum turbidity at the layers above or upper the halocline. As a result, the distributions of DO and turbidity in the upper regions of brackish Lake Sihwa were largely affected by the variation of salinity. Also, when the halocline was formed, the water quality between upper and lower water layers may be expected completely different. This study suggests that the physicochemical characteristics of water in the brackish regions are closely associated with the causes of eutrophication such as red tide and DO deficit.

Arsenic contamination in soil and groundwater has recently been one of the most serious environmental concerns. This arsenic contamination can be originated from natural or anthropogenic sources. It has been well known that arsenic behavior in geo-environmental is controlled by various oxides or hydroxides, such as those of iron, manganese, and aluminum, and clay minerals. Among those, particularly, iron (oxy)hydroxides are the most effective scavengers for arsenic. For this reason, this study characterized arsenic adsorption of magnetite which is a kind of iron oxide in nature. The physicochemcial features of the magnetite were investigated to evaluate adsorption of arsenite [As(III)] and arsenate [As(V)] onto magnetite. In addition to experiments on adsorption equilibria, kinetic experiments were also conducted. The point of zero charge (PZC) and specific surface area of the laboratory-synthesized magnetite used as an arsenic adsorbent were measured 6.56 and $16.6\;g/m^2$, which values seem to be relatively smaller than those of the other iron (oxy)hydroxides. From the results of equilibria experiments, arsenite was much more adsorbed onto magnetite than arsenate, indicating the affinity of arsenite on magnetite is larger than arsenate. Arsenite and arsenate showed adsorption maxima at pHs 7 and 2, respectively. In particular, adsorption of arsenate decreased with increase in pH as a result of electrical repulsion caused by anionic arsenate and negatively-charged surface of magnetite. These results indicate that the surface charge of magnetite and the chemical speciation of arsenic should be considered as the most crucial factors in controlling arsenic. The results of kinetic experiments show that arsenate was adsorbed more quickly than arsenite and adsorption of arsenic was investigated to be mostly completed within the duration of 4 hours, regardless of chemical speciation of arsenic. When the results of kinetic experiments were fitted to a variety of kinetic models proposed so far, power function and elovich model were evaluated to be the most suitable ones which can simulate adsorption kinetics of two kinds of arsenic species onto magnetite.

The probability of T/S cargo volume to decrease is the most notable problem associated with inappropriate mix of terminal operators in Busan port. Other problems include, the deterioration of the national carriers' competitiveness from non-operation of own terminal, excessively high proportion of financial operators in the engagement of operation which may result in their passiveness in timely investment, additional cost burden to carriers' in the handling inter-terminal T/S cargo transportation and inefficiency in terminal operation by the multiplicity of operators proved to be same recognized as so through the analysis. Therefore, in order to provide solutions for the problems and to strengthen Busan port's competitiveness, this research suggests the restructuring of operators mix as follows. To achieve sustainable growth of T/S cargo, global carriers' participation in terminal operation should be of utmost priority. To enhance the operational efficiency, the operators should be integrated. Similarly, the integration of operators will play a key role in verifying that national carriers' own terminal operation is an important factor in raising its competence. Finally, BPA's active engagement in the entire operation of port is also critical in public-oriented operation of the port. Whereas in the interactive analysis by taking the merits of Busan port into consideraion, global carrier's participation in operation, integration of operators and BPA's engagement in operation proved to contribute to the increase of T/S cargo and strengthening of operational efficiencies of Busan port.

Archaeological heritages are precious cultural relics and public assets that must be preserved, conserved, and shared with people all over the world. Investigating archaeological heritage is valuable and plays an important role for the public good; our ancestors' cultures can be restored, and it helps with developing a clear understanding of the cultural and social aspects of a historical period as well as teaches about historical factors unreported in the literature. One of the most basic and important conditions necessary for recognizing the value and importance of archaeological heritage investigation, expertise, and quality improvement is to establish detailed criteria for investigation services and the qualification examination of archaeological heritage. Observation of detailed criteria and the qualification examination of archaeological heritage can partially demonstrate society's recognition of strengthening transparency, public property, and the objectivity of the investigation of archaeological heritage. However, the detailed criteria for investigation services and the qualification examination of archaeological heritage currently implemented as administrative rules are neither followed by all institutes in the public and private sectors nor the government. Thus, there are serious problems in terms of the effectiveness and stability of institutions. The detailed criteria for the qualification examination breach the principle of statutory reservation, the principle of statutory regulation, and regulations on the announcement and management of orders and rules. Non-compliance with compensation criteria for investigation services or with detailed criteria for the qualification examination of archaeological heritage will be one of the reasons for the failure of the investigation foundation for archaeological heritage in the future. That is, it will result in the expansion, reproduction, and repetition of a vicious cycle of conflict between developers, who are the decision-makers responsible for selecting an investigating organization for archaeological heritage and determining the cost, and investigating organizations. This includes the impractical shortening of investigation periods and reducing costs by developers, distrust of the values and the importance of investigations of archaeological heritage, a decrease in quality, accidents caused by a lack of safety, a lack of occupational ethics, and non-recruitment of new experts, etc. Therefore, it is necessary to change the structure from a vicious cycle to a virtuous cycle, and promote the enactment of regulations that will ensure effectiveness and stability in the process of attaining the goals of the institution and application of the institution, as well as the continuous advancement of work to fill the gaps with reality.

Danggol, in other words the hereditary shaman, is a person who is performing the Gut(the Korean shamanistic ritual) as the job but fortuneteller simply tells someone's fortunes. Nowadays most of fortunetellers think their works are wholly managed the Gut as the holy jobs. But Generally this kinds of jobs, we think it is lower than ordinary people's level of education in the korea. Actually we can meet eleven fortunetellers who have a college diploma out of them, so we can know that their education's level is increasing gradually. On the other hand a house of fortunetellers is the place where can lead the way of our lives in the method of seeing one's past life or making predictions of someone's coming events etc. Gradually this place seems to be separated with a private home, so the most of them is managing as the monthly rent. Consequently this houses are heavily located at the Gyerim five-way crossing, the Yang-dong Dakjeonmeory street, Jungheung-dong local culture street area. Each fortunetellers have the different ways of fortune-telling because this methods are decided by their one's characters. So their fortune-telling time and its time required for a task is far different. The methods of telling it is very much different in accordance with the learning fortuneteller or spiritualistic fortuneteller. But the process of fortune-telling is common like as a preparatory stage, carrying a Jumsa(fortune-telling) stage and acting by a Jumsa stage. These steps are sequential but linked together. There are six special features of fortune-telling culture in Gwang-Ju. 1. The role of a fortuneteller and Bosal(spirit-descended shaman) runs at the same time. 2. The house of fortune-telling is doing Gutdang(ritual house)'s works. 3. Its location are heavily collectivized at the specific districts. 4. The learning fortuneteller are increasing gradually. 5. The youth are growing use in the fortune-telling house. 6. There are many person that are visiting this house because of individual problems not their family's problems.
