Based on surface energy balance climatology, surface temperatures should respond to drying conditions well before plant response. To test this hypothesis, land surface temperatures (LST) derived from MODIS data were analyzed to determine how the data were correlated with climatic water balance variables and NDVI anomalies during a growing season in Western and Central Kansas. Daily MODIS data were integrated into weekly composites so that each composite data set included the maximum temperature recorded at each pixel during each composite period. Time-integrated, or cumulative values of the LST deviation standardized with mean air temperatures had significantly high correlation coefficients with SM, AE/PE, and MD/PE, ranging from 0.65 to 0.89. The Standardized Thermal Index (STI) is proposed in this study to accomplish the objective. The STI, based on surface temperatures standardized with observed mean air temperatures, had significant temporal relationships with the hydroclimatological factors. STI classes in all the composite periods also had a strong correlation with NDVI declines during a drought episode. Results showed that, based on LST, air temperature observations, and water budget analysis, NDVI declines below normal could be predicted as early as 8 weeks in advance in this study area.

This study attempted to classify the types of perceptions of the new Hanbok, focusing on female college students in their 20s, and to analyze the characteristics of each type. This study was conducted with the Q methodology and analyzed with the QUANL pc program. The perceptions of the new Hanbok among female college students in their 20s were classified into four types: Type 1: modern/practical, Type 2: convenient/practical, Type 3: temporary/accessible, and Type 4: convenient/traditional. Type 1 emphasized the selection of Western clothing fabric, matching zipper/buttons, and achromatic colors. Type 2 highlighted a design that can be worn as daily clothing by combining materials that are convenient for laundering. Type 3 stressed the operation of new Hanbok rental stores so that it is easy to access and accept new Hanboks in old palaces and Hanok villages. Type 4 required the development of a design that reflects the elements of the traditional Hanbok and is convenient for activity and laundering.

Red sea bream iridovirus (RSIV) obtained from infected rock bream was propagated by Bluegill fry-2 (BF-2) cell culture. The virus titer was determined as $10^{5.5}\;TCID_{50}/ml$ on confluent BF-2 cell monolayers. The integrin binding site of ORF 055L of infectious spleen and kidney necrosis virus (ISKNV) was selected for the construction of a primer to obtain the RSIV ORF 055L gene. The genes were amplified using RSIV gene lyzate by PCR. The homologies of the ORF 055L sequence of RSIV with ISKNV and rock bream iridovirus (RBIV) were approximately $96\%$ and $100\%$, respectively. DNA vaccine was constructed by cloning the ORF 055L of RSN into pcDNA 3.1 (+), containing a cytomegalovirus (CMV) promoter. For antibody production, pcDNA-055 DNA vaccine was injected to BALB/c mice. The production of antibodies against pcDNA-055 DNA vaccine was confirmed by the Western blot analysis. The antibodies produced by the pcDNA-055 DNA vaccine showed efficacy to neutralize the RSIV in the neutralization test in BF-2 cell culture.

Suncheonman-Bay and its surrounding areas play important roles as habitats for migratory birds. However, sustainable management of these areas is difficult because of the development pressure of private lands. Therefore, the areas surrounding Suncheonman-Bay must be classified as additional protected areas; for this, it is necessary to gather concrete and objective evidence and ensure protected area management. Further, compensation measures must be considered when acquiring a private property as an additional protected area. In this study, we distinguish protected areas, such as core, buffer, and transition areas, within a private area by using data from the Winter Waterbird Census of Korea and MARXAN software, a spatial conservation prioritization tool. We applied ecosystem services to apply Payment for Ecosystem services (PES) as compensation measures. Watershed conservation (supply), climate control (regulation), supporting habitats (support), and recreation (culture) etc. were evaluated by calculating the economic value of these ecosystem services. Eastern, western, and northern forests and rice fields of Suncheonman-Bay were shown to have a number of core areas for the preservation of endangered species. The ecosystem service value of the additional protected areas was estimated at 17.5 million KRW/ha/year. We believe that our study result could be used to establish protected areas to preserve major habitats, as well as include areas adjacent to such major habitats that play a vital role in endangered species conservation. In addition, through this study, we highlight the need for an objective basis to establish protected areas.

The Purpose of this study is development and analysis of Effluence Characteristic of the Rainfall in the IRMA Green Roof System(developed in KICT) Plus 50 program is an internal research project at KICT(Korean Institute of Construction Technology) which has it as an object ; to lengthen the building's life 50-year or more and reduce energy conception 50% than present. Green roof system is one of the most important theme in the Plus 50 program. Generally, a Green Roof System has a positive effect on the thermal conductivity in winter, the micro cooling effect on building and city by evaporation in summer, the flood-control effect by runoff-reduction or the treated rainwater-quality of green roof system and so on. However, inspection of the physical effect of green roof system does not consider in Korea. Above all, long-term monitoring and a whole observation of green roof system is needed to probate the effect. So a new experimental method could be tried in this research, which is never attempted in Korea. The measurement by a bucket with a great volume, 1L, gives a new dimension of measuring green roof effect to measure the permanent running flood from a wide roof. This offers a reasonable result on a long-term measuring of a running water. Additionally, the thermal behavior of the IRMA(Insulated Roof Membrane Assembly), known in the western europe as a reasonable solution at green roof system by economical benefits and easy construction, would be experimented.

Teacher quality is a topic of international concern, as it impacts student learning and teacher preparation. This study compared the undergraduate secondary science teacher preparation programs from two universities in Korea with those of Oregon, USA. We examined the programs' structural curricular coherence, conceptual curricular coherence, and curricular balance. Structural curricular coherence was determined by examining the overarching goals of the institutions' programs, the organization of the programs of study in terms of meeting those goals, and outside bodies of evidence. All universities were in structural coherence for various reasons. Conceptual curricular coherence was determined by examining students' perceptions of the connection between their preparation and their clinical practice. In case of Korea, most students from both universities were not satisfied with their practical preparation. In the US, the students from both institutions felt well prepared to transition to inservice teaching. To determine curricular balance, we examined the institutions' preparation programs looking at the credit hours taken in the four main areas of the teacher knowledge base: GPK (General Pedagogical Knowledge), SMK (Subject Matter Knowledge), PCK (Pedagogical Content Knowledge), and CK (Contextual Knowledge). The total credit hours taken in each category was very similar by country but the application and field component in the USA was far greater than those of Korea where the focus was heavily on SMK and PCK. The main reason for these may be the nations' licensing and employment processes.

The challenge of predicting the Japanese coastal ocean motivated Frontier Observational Research System for Global Change (FORSGC) and the Japan Marine Science and Technology Center (JAMSTEC) to start a multiyear observational programme in the upstream Kuroshio in November 2000. This field effort, the Kuroshio Observation Program (KOP), should enable us to determine the barotropic and baroclinic components of the western boundary current system, thus, to better understand interactions of the currents with mesoscale eddies, the Kuroshio instabilities, and path bimodality. We, then, will be able to improve modeling predictability of the mesoscale, seasonal, and inter-annual processes in the midstream Kuroshio near the Japanese main islands by using this knowledge. The KOP is focused on an enhanced regional coverage of the sea surface height variability and the baroclinic structure of the mainstream Kuroshio in the East China Sea, the Ryukyu Current east of the Ryukyu's, and the Kuroshio recirculation. An attractive approach of the KOP is a development of a new data acquisition system via acoustic telemetry of the observational data. The monitoring system will provide observations for assimilation into extensive numerical models of the ocean circulation, targeting the real-time monitoring of the Japanese coastal waters.

Rhinitis and sinusitis are among the most common medical conditions in Korea, as well as Western societies. Environmental factors may influence both rhinitis and sinusitis; however, the role of dietary factors in rhinitis and sinusitis is not clear. The present study aims to compare the dietary habit, food consumption frequency, and food preference of elementary school students with or without rhinitis and sinusitis. The demand of their parents for an education program for the dietary prevention against rhinitis and sinusitis was also examined. The survey was conducted with a total of 200 subjects recruited from two elementary schools located in Gyeonggi area of Korea. The subjects consisted of 101 students with rhinitis and/or sinusitis (RS group) and 99 without rhinitis and sinusitis (control group). The students of the RS group were more likely to have habits of eating-out and street food use, to consume bean, peanut, walnut, almond, yogurt, egg, snack, and French fries frequently, and to prefer the types of foods prepared by stir-frying and deep-frying than the control group. The parents who recognized 'school nutrition teachers or food/nutrition-majored specialists' as the most appropriate educator for the dietary education program in the RS group (48.5% of their parents) were less than those in the control group (67.7% of their parents). The present study suggest that students with rhinitis and/or sinusitis may be different from those without the disease(s) in their dietary habit, frequently consumed foods, and preferred type of foods. More epidemiological, intervention, and laboratory studies are needed in order to elucidate the role of dietary factors in the development and prevention of rhinitis and sinusitis, which will have a significant implication to public health.
