The International Civil Aviation Convention (Chicago Convention) has been a backbone of international air transport system whereby air transport between States should be based on bilateral agreements, and in particular, international airfares, which are set up through IATA(International Air Transport Association) rate-fixing machinery could be approved by the governments concerned. International airfares are fares for transporting passenger and freight and their conditions between two or more countries. However, since U.S. pursued th deregulation policy in 1978 whereby routes, capacity and fares could be freely determined by airlines, many States have been following so called open-skies agreements. In many cases, aeronautical and competent authorities have been reviewing whether airlines' commercial activities including air fares could possibly conflict with free competition rules envisaged in relevant laws and regulations. As competition among airlines gets intense, airlines often resort to cooperation with other airlines in the forms such as equity exchange, M&A, code-sharing, fares consultation and resource pooling, mainly with a view to effectively use resources available and to avoid monopoly situation resulting from excessive and destructive competition among players. Whereas bearing in mind that application of competition laws is important to secure consumers' interests by preventing airlines's malpractices such as bargaining exorbitant fares, it is also important to comprehensively consider as many factors as possible, from that unilateral measure by governments may bring about retaliatory measures by the governments affected, to that airlines' cooperative practices may rather increase consumers' benefits by lowering air fares.

The world-wide principal criteria of aircraft operations is ICAO Annex 6. Operations of Aircraft. Among ICAO Annex 6, Part I is for International Commercial Air Transport - Aeroplanes and it assumes major part of civil aviation. ICAO has been providing Contracting States with SARPs(Standards and Recommended Practices) and monitor each State's reflection degree into their domestic air law, so-called USOAP(Universal Safety Oversight Audit Program). Current ICAO USOAP is Snap-shot method, but it will be changed to USOAP-CMA method from the year of 2013. ICAO USOAP results have overall effects on national aviation industry such as routes, insurance, airlines cooperation and so forth. Low grades of results attract international attention and that leads to flag carrier's operation stoppage, route restriction, airlines cooperation restriction, insurance increase directly or indirectly. Thus it is important to get excellent grades in ICAO USOAP and to maintain confidence. Our government ranked top to get 98.89 grades in 2008 ICAO USOAP but after 2008 the revised provisions have not been reflected sufficiently into our air law. So I would like to grip reflection ratio of ICAO Annex 6 Part I into our domestic air law by using the most updated revised edition on this paper. Together I would like to suggest alternatives for the non-reflected and partially reflected.

Exposure to HDI(hexamethylene di-isocyanate) commonly used in vehicle crash repair workshops remains a leading cause of occupational asthma. Although skin and eye contamination are considered as absorption routes, there are no occupational exposure standards for skin and ocular exposure. This is the reason why there are more empirical data should be provided. Therefore this study was to determine contamination levels of HDI on the skin, eyes, work surfaces, respirators and eye protectors. There was evidence of contamination on a variety of work surfaces, for example, door handles, bench top and spray gun, etc. A high proportion(47~80%) of skin wipe samples from neck, forehead, back hand, palm and wrist was positive for HDI contamination, even though spray time was relatively brief. The contamination levels from spraying inside spray booth were generally higher than outside booth due to poor work practices and inappropriate personal protective use like safety gloves. Apprentices had higher exposure levels than the qualified painters, likely due to lack of the recognition of safety and hygiene. The extent of contamination inside the PPE might provide an indication of the potential for respiratory & skin exposure and ocular exposure. Eye fluid samples from 4 out of 14 workers had the positive detection of HDI contamination, due to poor work practices like no or inappropriate eye protection. Considering the potential for dermal & ocular exposure to contribute to possible health symptoms including respiratory sensitization, the empirical data point to a need for improving work practices and appropriate PPE selection, use and maintenance.

With the flow of globalization, world aviation markets are showing growing trends toward liberalization, deregulation, and privatization. At the same time, also apparent is a strong trend toward regionalism on aviation markets to realize open skies at the regional level. This research examines the recent trend of regionalism in the world aviation market from a political economic perspective, taking a single European aviation market as an example. The results show that the creation of a single European aviation market is the EU's strategic response against the US to enhance the European aviation industry's competitiveness. More specifically, the results show that the European countries are creating a single European aviation market in order to stand against the US' so-called 'divide and nile policy' and 'encirclement strategy' and to make their airliners to have competitive advantages over the US airliners on the lucrative North-Atlantic air routes. Recently, the single European aviation market is expanding by including the Mediterranean and Balkan states to pursue Pan European aviation cooperation and to develop European Common Aviation Area so that it can continuously enhance its negotiating leverage against external markets. The results imply that it is urgent for the Northeast Asian countries to create their own regional aviation bloc to develop their aviation industry and to increase their negotiating power against external countries.

This study was conducted to investigate the user's effects on the avifauna in Kaya Mountain National Park. The survey was carried over 3 districts which were divided with main trail(valley), subtrail(valley), unused trail(ridge) by line transect method from April to October 1989. The observed birds were 29 species and 527 individuals. these consist of 20 species for residents, 7 species for summer visitor 1 species for winter visitor, 1 species for passage migrant. The average density of birds was 2.44 ea/ha, and main dominant species were Parus major minor, Garrulus gtandarius brandtii, Parus palustris hellmayri, Parus varius and Sitta europaea amurenis in order. The observed frequency of wild birds was 8.42 times/km in average. No. of species, no. of individuals, density, species diversity and observed frequency of summer were lower than spring in 3 survey routes. Therefore, from now, in Kaya Mountain National Park management, the enjoyment oriented activities will be regulated and control of trail use on main trail are necessary during breeding periods for wild birds protection, especially in summer. To investigate the use or not of artificial nests, 35 artificial nests were selected. The results of this survey showed that many wild birds prefered mixed nest in column shaped to wooden nests. The rightful installation and manegement for invitation and increase of wild birds was necessary.

The cotton aphid, Aphis gossypii Glover (Hemiptera: Aphididae) infests citrus orchards, causing sooty mold damage to the fruits. This study was conducted to investigate the colonizing route of A. gossypii in citrus orchards in a non-heating plastic-film house during the early season. The overwintering eggs of the aphids are frequently found on summer shoots of the citrus trees. The eggs were mostly those of Aphis citricola, without any A. gossypii when hatched. The colonization of citrus trees by alate A. gossypii in non-heating plastic-film houses was mainly observed twice, with advanced flight in late April and delayed flight in late May. The delayed flight was synchronized with the timing of the emergence of alate A. gossypii from the fundatrix generation in the holocyclic life cycle. During advanced flight in closed citrus orchards, alate A. gossypii were caught in yellow water traps installed in the fields, and the populations were found to originate from the surviving populations of the anholocyclic life cycle. Consequently, we concluded that citrus tree colonization with A. gossypii occurred during the advanced flight of the anholocyclic and the delayed flight of the holocyclic life cycle.

This study estimated the regional economic effects by development of the logistics complex in Incheon New Port, applying the regional Input-Output tables in Incheon. And thereby, we tried to find some strategic implications on the priority to induce more effective industries for activated operation of the logistics complex in ports. According to the results, development of Incheon New Port will generate 2,579 billion KRWs(2.2 billion USDs) of production and 1,783 KRWs(1.5 billion USDs) of value-added annually. And we expect it to induce 38.8 thousand jobs, which is over the national average on the input-output table. By the business type, port logistics industry will contribute to develop regional economy more than any other ones in Incheon. We suggest business firms in port logistics industry to be induced to the logistics complex in Incheon New Port strategically. Until now, development of the logistics complex in Incheon New Port are planned to be postponed to 2015 when construction of the berth facilities, the access sea routes and the hinterland highways are completed. We suggest to invest more public fund, to induce the private capital, and then, to develop the logistics complex in Incheon New Port earlier in an appropriate scale.

Despite the legal and institutional measures that have been enacted for the safety management of school facilities, the number of school accidents has continued to rise, particularly in regards to the number of accidents related to schools. However, school facilities have had a difficult time creating safe school environments for the school administration and local governments. This is due to the fact that the Office of Education and the Ministry of Education, not the school or educational offices, have insufficient institutional devices such as standards and systems for the promotion of safe school environments. This study attempted to confirm the direction of the improvement of the safety of school facilities. To this end, four safety assessment topics (separation of pedestrians, pedestrian path management, pedestrian visibility, and surrounding risk factors) were derived based on the surveyed data for the safety of the external environment of domestic and international school facilities. 179 school facilities nationwide (kindergartens, elementary schools, middle schools, high schools, and special schools) were analyzed for current cases of accidents that occurred mainly on school roads. Roughly 50% of the analyzed evaluation scores showed that it is necessary to improve the external environment of school facilities.

Emergencies and disasters can happen any time without any warning, and things can change and escalate very quickly, and often it is swift and decisive actions that make all the difference. It is a responsibility of the building facility management to ensure that a proven evacuation plan in place to cover various worst scenario to handled automatically inside the facility. To mapping out optimal safe escape routes is a straightforward undertaking, but does not necessarily guarantee residents the highest level of protection. The emergency evacuation navigation approach is a state-of-the-art that designed to evacuate human livings during an emergencies based on real-time decisions using live sensory data with pre-defined optimum path finding algorithm. The poor decision on causalities and guidance may apparently end the evacuation process and cannot then be remedied. This paper propose a cloud connected emergency evacuation system model to react dynamically to changes in the environment in emergency for safest emergency evacuation using IoT based emergency exit sign system. In the previous researches shows that the performance of optimal routing algorithms for evacuation purposes are more sensitive to the initial distribution of evacuees, the occupancy levels, and the type and level of emergency situations. The heuristic-based evacuees routing algorithms have a problem with the choice of certain parameters which causes evacuation process in real-time. Therefore, this paper proposes an evacuee routing algorithm that optimizes evacuation by making using high computational power of cloud servers. The proposed algorithm is evaluated via a cloud-based simulator with different "simulated casualties" are then re-routed using a Dijkstra's algorithm to obtain new safe emergency evacuation paths against guiding evacuees with a predetermined routing algorithm for them to emergency exits. The performance of proposed approach can be iterated as long as corrective action is still possible and give safe evacuation paths and dynamically configure the emergency exit signs to react for real-time instantaneous safe evacuation guidance.
