The Russia-Ukraine War was a "three-layer compounded war" between the US and Russia, Russia and Ukraine, and Ukrainian government forces and rebels. First, the war is a phenomenon that occurred when the western sphere of influence seeking to maintain and strengthen the liberal international order and the Sino-Russian sphere of influence seeking a new alternative order collided in Ukraine, a geopolitical fault zone. Second, this war is the result of a typical 'security dilemma' phenomenon caused by the 'chain reaction' game of NATO's continuous expansion and Russia's response. Third, the Russia-Ukraine war was caused by the Russian military projection to prevent the military restoration of Donbas region by Ukraine. Until now, the Western world, led by the US, showed unexpected solidarity after the war despite subtle differences in positions. However, the non-Western world, including China, is not participating in the condemnation and sanctions against Russia. This war will be an important turning point in the existence and change of the current international order that has been formed and is operating since the end of the Cold War. The direction of maintenance/restoration, revision/change, and end/transformation of the current international order is highly likely to be determined depending on the development pattern and method of ending the war.

After global economic crisis, most countries increased the welfare expenditure as a part of stimulus package. As a However welfare expenditure was decreased radically as the crisis was transmitted into the financial crisis. Which turning point is the welfare state going through now? Although the need for the welfare and the role of the state to take responsibility of public welfare has increased because of poverty and polarization, responses of the state against the crisis had focused on the aid to the financial industry and cutting taxes and showed limitations in coordination. Financial limitation of welfare expenditure, political individualism, the change of class politics and the mixture of the welfare institutions and financial institutions make have a pessimistic prospect of the retrenchment to the minimalist welfare state. As neoliberal state is continued cash benefits mainly for the middle class is being decreased. As a result, the direction the welfare states pursue is prospected to win over the poor by strengthening selectivity in welfare provision rather than class coordination.

Master Jeungsan understood a general view of Pungsu but actually he used the theory of Pungsu in his own religious perspective, transcending it. The theory of Pungsu is different. But the fact that it is premised on the principle of 'in and yang', the five-element principle, the Book of Changes, energy thought, and To chugi piyung, etc. is generally recognized. The three important elements of Pungsu are mountain, water, and direction or man. Pungsu has formal principles such as Gallyongbeop, Jangpungbeop, Deuksubeop, Jeonghyeolbeop, Jwahyangbeop, and Hyeongukron. etc. In the late of Joseon, Jeungsan established a new traditional thought, understanding Bibopungsu, Gukdopungsu, Minganpungsu, etc. However, he reinterpreted them to be suitable to his religious ideal and let his followers understand them as well. In particular, Jeungsan overcame the previous view on earth and expressed a new perspective to enhance earth up to the level of heaven. In the perspective of the traditional world, earth is lower than heaven, but Jeungsan made it a status equal to heaven. He mentioned that in the past, the culture and history of man was influenced by earth's energy but today, at the age of man respect, he put passive man influenced by earth-condition on the more subjective and active status. Even though he mentioned different Pungsu, Hyeongguk, and Hyeolmyeong, he expressed the shape of Pungsu within the construction of three worlds, the one of heaven and earth transcending good or ill luck or a favorable change in fortune. He practised the expedient of Pungsu from the stand of the construction of heaven and earth instead of the usage of Bibopungsu, Gukdopungsu, and Minganpungsu. He diagnosed that the division of the world is caused by the one of earth and tried to solve it. Moreover, he said that Myeongdang(a propitious site) must be the man-orientation rather than the earth-orientation. It means that Pungsu, stressing the energy of earth and turning one's luck, is changing into the world of man-orientation. In other words, Jeungsan diagnosed the world of Pungsu but he ultimately used Pungsu theory in building up his own view of religious world transcending such a theory.

This paper presents an optimal path planning strategy for aerial searching and surveying of a user-designated area using multiple Unmanned Aerial Vehicles (UAVs). The method is designed to deal with a single unseparated polygonal area, regardless of polygonal convexity. By defining the search area into a set of grids, the algorithm enables UAVs to completely search without leaving unsearched space. The presented strategy consists of two main algorithmic steps: cellular decomposition and path planning stages. The cellular decomposition method divides the area to designate a conflict-free subsearch-space to an individual UAV, while accounting the assigned flight velocity, take-off and landing positions. Then, the path planning strategy forms paths based on every point located in end of each grid row. The first waypoint is chosen as the closest point from the vehicle-starting position, and it recursively updates the nearest endpoint set to generate the shortest path. The path planning policy produces four path candidates by alternating the starting point (left or right edge), and the travel direction (vertical or horizontal). The optimal-selection policy is enforced to maximize the search efficiency, which is time dependent; the policy imposes the total path-length and turning number criteria per candidate. The results demonstrate that the proposed cellular decomposition method improves the search-time efficiency. In addition, the candidate selection enhances the algorithmic efficacy toward further mission time-duration reduction. The method shows robustness against both convex and non-convex shaped search area.

This is the basic study in order to know the amount of transpirational water loss in a Larix leptorepis stand by a heat pulse method. Especially this study has been measured and discussed the diurnal and seasonal trends of heat pulse velocity by changes of radiation, temperature and humidity, differences of heat pulse velocity by direction and depth in stem, differences of heat pulse velocity by dominant, codominant and suppressed trees, diurnal change of heat pulse velocity by change of leaf water potential, sap flow path way in sapwood by dye penetration and amount of daily and annual transpiration in a tree and stand. The results obtained as follows : 1. Relation between heat pulse velocity(V) and sap flow rate(SFR) was established as a equation of SFR=1.37V($r=0.96^{**}$). 2. The sap flow rate presented in the order of dominant, codominant and suppressed tree, respectively. The daily heat pulse velocity was changed by radiation, temperature and vapor pressure deficit. 3. The heat pulse velocity in individual trees did not differ in early morning and in late night, but had some differed from 12 to 16 hours when radiation was relatively high. 4. The heat pulse velocity and leaf water potential showed similar diurnal variation. 5. The seasonal variation of heat pulse velocity was highest in August, but lowest in October and similar value of heat pulse velocity in the other months. 6. The heat pulse velocity in stem by direction was highest in eastern, but lowest in southern and similar velocity in western and northern. 7. The difference of heat pulse velocity in according to depths was highest in 2.0cm depth, medium in 1.0cm depth, and lowest in 3.0cm depth from surface of stem. 8. The sap flow path way in stem showed spiral ascent turning right pattern in five sample trees, especially showed little spiral ascent turning right in lower part than 3m hight above ground, but very speedy in higher than 3m hight. 9. The amount of sap flow(SF) was presented as a equation of SF=1.37AV and especially SF in dominant tree was larger than in codominant or suppressed tree. 10. The amount of daily transpiration was 30.8ton/ha/day and its composition ratio was 83% at day and 17% at night. 11. The amount of stand transpiration per month was largest in August(1,194ton/ha/month), lowest in May (386ton/ha/month). The amount of stand transpiration per year was 3,983ton/ha/year.

In this paper the problem of a moving control of an automatic guided vehicle(AGV) which transports a dead body to a designated cinerator safely in a crematorium, an special indoor environment, will be discussed. Since a method of burying guided lines in the floor is not proper to such an environment, a method of moving control of an AGV based on infrared ray sensors is now proposed. With this approach, the AGV emits infrared ray to the landmarks adheres to the ceiling to find a moving direction and then moves that direction by recognizing them. One of the typical problems for this method is that dead zone and/or overlapping zone may exist when the landmarks are deployed. To resolve this problem, an algorithm of recognizing double landmarks at each time is applied to minimize occurrences of sensing error. In addition, at the turning area to entering the designated cinerator, to fit an AGV with the entrance of the designated cinerator, an algorithm of controlling the velocity of both the inner and outer wheel of it. The functional correctness of our proposed algorithm has been verified by using a prototype vehicle. Our real AGV system has been applied to a crematorium and it moves automatically within an allowable range of location error.

In case of treating the functional type of anterior cross bite, removing the cause in early stage prevents from turning to skeletal type, leads to perform normal function, and has improved facial appearance. Functional Regulator III (FR III), one kind of the Functional regulator(FR)s suggested by R$\ddot{o}$lf Fr$\ddot{a}$nkel in 1966, applied to patients with the functional and skeletal anterior crossbite in early mixed, and permanent dentition. This appliance improves unbalanced power condition by blocking abnormal muscle-power effect, so that normal growth can be expected. In this case report, favorable results were obtained by selecting clinical cases of children in their early mixed dentition with functional cross bite. 1. FR IIIs were applied to patients with anterior crossbite for 5~6 months. Anterior crossbite patients were corrected favorably, nevertheless they didn't show any horizontal skeletal-changes by buccal shields. 2. Normal occlusion and esthetic facial contour were achieved from dental movement of maxillary and mandibular anterior teeth while the mandible rotates to posterior and inferior direction.

The Full-length examination of the femur sometimes does not show all of the femur because of the limited width in collimator and size of detectors although it is located in the diagonal direction. Aim of this study is to identify usefulness of the method of combining images which obtained from two radiographic images containing the femoral head and condyle respectively. Our group interviewed 30 radiological technologists who used both palliative DR method and SM method in their examinations of the femur of patients who were carried to the emergency rooms in Gwang-ju city from August 2007 to November 2009. We evaluated twenty images according to the contraction of femoral neck, turning of knee joints and inclusion of the femur. The examination were performed by two radiologists and six radiological technologists who have more than ten years of career. The results are as follows: SM method was graded with higher score for examination time, number of examiners, emaciation, retake and patients' discomfort (p< 0.001) while the. SM method was scored higher than the palliative DR method in the palliative DR method for examination of long bone.

Self-reflexivity means consciousness turning back on itself and breaks with art as illusionism and exposes their own factitiousness as textual construct. Self-reflexivity in media deals with the media's condition and process itself and tends to pull viewers out of the reality represented on screen by reminding them that is a media's construction or illusion on the screen. Representation aesthetics has been recognized with an essential theory of the art since Ancient Greek, but it has encountered crisis with the invention of the photography and the cinema in the early 1900s. The supreme transparency of the new media induced a new perspective for the representation aesthetics, which had dominated the art world. The art derived from the representation stood on the crossroad of changing direction. Modernism aesthetics wanted to search for the self-referentiality in order to the replace the past principal. This essay focuses on self-reflexivity in animation and their methodology. First, the change of representation aesthetics in visual arts will be discussed. Second, animations exposing their process of production and components will be analyzed, and lastly, intertextuality in animation will be dealt. I hope to provide the vision of the expanded animation media with this study.
