The principal objective of this study was to investigate regional characteristics in the consumption of home-cooked varieties of kimchi and jangajji. Data obtained from the third Korea National Health and Nutrition Examination Survey III(KNHANES Ⅲ), which was conducted in 2005, were utilized in this study. A total of 7,810 data were included in our statistical analyses, which were conducted using SPSS 14.0. The total number of home-cooked kimchi and jangajji were 22 and 11, respectively, and Korean cabbage kimchi, young radish kimchi, and kkakdugi were the top 3 varieties of kimchi. Leaf jangajji, green pepper jangajji, and garlic jangajji were most frequently consumed. Additionally, the results of this study revealed significant correlations between neighboring areas in the ranking of consumption of kimchi varieties, whereas the jangajji varieties did not evidence results as distinct as were noted with kimchi. Different kimchi and jangajji variety consumption patterns were noted between the Middle West and South areas, coastal and inland areas, and cities and provinces. Spicy kimchi varieties, in particular, were enjoyed more frequently by households in the South than those in the Middle West. Further analysis using PROXSCAL multidimensional scaling demonstrated the proximity between areas in terms of kimchi and jangajji consumption patterns. In conclusion, more effort should be extended to encourage the consumption of home-cooked regional foods.

This study aims to identify the degree of heat island in summer in Gwangju. For the purpose the city was classified according to use and surface components and temperature of the city for 24 hours was measured. The period of measurement was from August 11 to 13. 2003(two days). As a result of the measurement, the daily standard temperature of the central business areas and downtown areas was about $26^{\circ}C$. That of new residential areas neighboring the downtown was $25.1^{\circ}C$, and that of the outer residential areas was $23.4^{\circ}C$. In comparison with the result that temperatures of the Gwangju University playground and the Gwangju Weather Bureau were $23.1^{\circ}C$ and $23.3^{\circ}C$ respectively, the temperature of the downtown was about $2.7^{\circ}C$ Higher and that of the new residential area in downtown was about $1.8^{\circ}C$ higher. And it was demonstrated that the downtown outer road under Mt. Mudeung is a low-temperature zone. When temperature of the city was measured based on surface components, the daily standard temperature of Gwangju Stream Bok-gae area was the highest, $24.2^{\circ}C$, followed by $23.6^{\circ}C$ of the downtown stream and $22.2^{\circ}C$ of the greens (city park) and the waterside area.

A simultaneous visualization of the behavior of bubbles and dry spots has been carried out for pool boiling of R-1l3 on a horizontal heater. From video imaging and image processing analysis, the formation of bubbles and dry spots occurs simultaneously, and therefore they should be considered as a synchronized concept rather than independent identities. The dry spot density is equivalent to the active site density in the region before CHF. At CHF point, large dry areas due to the coalescence of neighboring dry areas cover the heater surface.

Enormous apartment complexes in urban areas, temporary inversion state and heat island effect occur due to the strong sunshine and weak wind speeds which hinders the dispersion of air pollutants that are emitted from neighboring areas of apartment complexes. In this study, analysis were conducted by using the Fluent code based on the CFD(Computation Fluid Dynamics), including building layout, material, building height from the ground surface, the heat, analysis of flow field in the apartment complex. It was estimated that the temporal radiation inversion phenomenon during the daytime, which was caused by the weak wind speed and higher temperatures in the upper level, contributed to the stagnation of the air pollutants in the lower layer of the apartment complex.

A reinforced concrete building neighboring in Pusan or Ulsan where is directly exposed to salt water contrasting with other in land areas contains much salt content percolated from the outside that the high salt content percolates and diffuses through the inside of reinforced concrete; therefore, an immovable tunic surrounding it begins to be destroyed and eroded with high speed. At the time, the cross-sectional area and volume expansion of re-bar reinforcing result in being cracks make a rapid progress gradually until they appear in the surface of the one, the phenomenon such as being a thin layer or falling off the part of it causes a lowering of its durability and might collapse the concrete construction. So far, we've investigated into salt content of reinforced concrete constructions neighboring in a seaside district and damage by carbonation, and we came to a conclusion as follows: $\circled1$ Under the oceanic circumstance a concrete construction is influenced by sea water directly that contains much amount of salt content contrasting with other constructions on inland areas. $\circled2$ Because of chloride penetration the carbonation of reinforced concrete made a rapid progress until more than the covering thickness of re-bar. $\circled3$ An old reinforced concrete building which has been piled up salt injury and proceeding the carbonation of its cross-sectional area. $\circled4$ According to rapidly cracking from the inside to surface of reiforced concrete, the phenomenon of being a thin layer or falling off the part of reinforced concrete results in a lowering of durability and shortening the life-time of concrete construction itself.

This study has the purpose to reveal the differences of residents' satisfaction level & demand of community environment and recognized residents' improvement priority of community environment at 3 complexes at the big city in the provinces. The 3 residential complexes had differentiated developmental concepts; the residence-oriented complex, the residence-government mixed complex with an eco-friendly concept, and the outskirt residence-industry mixed complex. Followings are the results of the study. 1) The satisfaction of residents in the community environment correlates with the increasing convenience facilities after construction. In the new outskirt complexes of smaller cities, dissatisfaction occurs more with public transportation rather than the road system, so that efficient public transportation systems, inner and neighboring areas, is requisite. 2) Even in the residence-oriented complex, the education environment does not entirely account for satisfaction level; the green environment is also second in priority after the education environment. In the residence-government mixed complex with an eco-friendly concept, a good natural environment does not entirely account for satisfaction level; education environment is also second in priority after the natural environment. The supply of sufficient schools may be fulfilled in the ways of reform of the education zone with neighboring existing residential areas. In the outskirt residence-industry mixed complex of smaller cities, priority was placed more on the location and convenience; this explains the complex's poor access to downtown.

A spatial time series model was used for analyzing the method of spatial time series (not the ARIMA model that is popular for analyzing spatial time series) by using chicken pox data which is a highly contagious disease and grid data due to ARIMA not reflecting the spatial processes. Time series model contains a weighting matrix, because that spatial time series model influences the time variation as well as the spatial location. The weighting matrix reflects that the more geographically contiguous region has the higher spatial dependence. It is hypothesized that the weighting matrix gives neighboring areas the same influence in the study of the spatial time series model. Therefore, we try to present the conclusion with a weighting matrix in a way that gives the same weight to existing neighboring areas in the study of the suitability of the STARMA model, spatial time series model and STBL model, in the comparative study of the predictive power for statistical inference, and the results. Furthermore, through the Kalman-Filter method we try to show the superiority of the Kalman-Filter method through a parameter assumption and the processes of prediction.

The year 2010 has been regarded as a year of China's assertive diplomacy. A series of China's behavior--including China's critical reaction to the U.S. for its sales of weapons to Taiwan, the Dalai Lama's visit to President Obama, China's arbitrary designation of 'core interests' over the South China Sea, China's inordinate reactions to the sinking of the Cheonan and Yeonpyeong bombardment, and China's activities in the Senkaku/Diaoyu island areas--has served as the witnesses to China's assertive diplomacy in 2010. The major causes of China's assertive diplomacy can be summed up by three factors: potential power transition from U.S. to China; emerging China's nationalism; and the recession of the Tao Guang Yang Hui as a diplomatic principle. But a majority of Western sinologists claim that China's assertive diplomacy is defensive in terms of its character. China's neighboring states, however, perceive its assertive diplomacy as diplomatic threat. Due to these states' geographical proximity and capability gaps with China, these neighbors experience difficulties in coping with China's behavior. In particular, China's coercive economic diplomacy, in which China tends to manipulate the neighbors' economic dependency on China for its diplomatic leverage, is a case in point for China's assertive diplomacy. China's assertiveness seems to be continued even after the inauguration of Xi Jinping government. Although the Xi government's diplomatic rhetorics in "New Type of Great Power Relationship" and the "Convention for Neighboring States Policy" sound friendly and cooperative, its subsequent behavior, like unilateral announcement of Chinese Air Defense Identification Zone (CADIZ), does not conform with its rhetoric. Overall, China's assertiveness has been consolidated as a fashion of its diplomacy, and it is likely to continue in its relations with neighbors. As a neighboring state, the ROK should approach to it with more balanced attitude. In addition, it needs to find out a new diplomatic leverage to deal with China in accordance with its security environment, in which China plays a growing role.
