동해안 지역에서 발생되는 대형 산불의 원인은 건조주의보, 영동지역에서 불어오는 강한 바람, 소나무의 단순림, 임도 유무와 상태 등을 들고 있다. 조사 대상지인 삼척 검봉산 일대는 기존 소나무가 우점하는 곳으로 2001년 복원을 위해 소나무, 곰솔, 굴참나무 등을 조림하였고, 일부는 자연복원을 하였다. 복원 이후 21년 지난 현재 삼척 검봉산 일대 산불피해 복원지역의 식생은 크게 굴참나무-소나무군락, 소나무신갈나무군락, 곰솔-소나무군락으로 나누어지는 것으로 나타났다. 산불피해지 식생 회복은 굴참나무, 소나무, 곰솔 등 조림으로 현재 식생은 산불 발생 이전의 임상으로 회복되고 있다. 특히, 산불의 유형 중 지표화 피해지역은 하층 식생의 피해가 크다. 기존의 소나무는 결실된 종자를 비산하여 치수를 발생시켜 자연복원의 속도를 높이고 굴참나무를 활용한 인공복원은 맹아를 발달시켜 본인의 영역을 확장하는 전략을 지니고 있다. 단, 입지적 환경이 동일하다는 전제 조건에서 숲에서 재생 기작이 진행되는 자연복원보다는 인공복원이 회복시간과 종다양성이 높은 측면에서는 효과적인 것으로 결론을 지을 수 있다. 식생군락을 분류한 결과 굴참나무-소나무군락, 소나무-신갈나무군락, 곰솔소나무군락으로 3개 군락으로 나누어졌다. 인공복원지에 식재한 굴참나무, 소나무, 곰솔은 복원 이후 지속적으로 해당지역의 식생이 우점종으로 자생하고 있는 것으로 나타났으나, 소나무-신갈나무군락의 경우 참나무과 식물인 신갈나무와 굴참나무, 졸참나무가 교목층과 아교목층에 자연유입되고 있어 향후 신갈나무가 우점하는 활엽수림으로 천이 될 것으로 예상된다. 군락의 종다양도지수는 낙엽활엽수가 우점하는 굴참나무-소나무군락이 가장 높게 나타났으며, 침엽수림인 곰솔소나무군락이 가장 낮게 나타났다. 산불피해지 식생은 조림수종에 영향을 크게 받으며, 21년이 지난 현재 산불 이전 임상으로 회복되는 경향을 나타내었다. 향후, 효과적인 복원을 위한 DB구축 및 모니터링자료 마련을 위해 산불피해지에 대한 지속적인 식생조사를 통한 자료구축이 필요하다.

For the last 70 years, the U.S.-led bilateral security system, or "Hub-and-Spokes" system, has been applied to Northeast Asia, and the system has been successfully settled in terms of stability and economic achievements of the region. Given the increasing complexity of the security environment of East Asia, it is plausible to consider the possibility of a security system shift from bilateral alliances to collective security. In order to analyze the driver of collective security system, this study developed three factors of formation and development of collective security system - main threat, intensity of the threat, and confidence among countries in the system - by reviewing international political theories related to security cooperation. Comparing the formation, development, and achievements of NATO and SEATO, the study figures out that the existence of the main threat, the high intensity of the threat, and the strong confidence among countries in the security system are the primary drivers for a successful collective security system. Based on the result, the study also analyzed the possibility of a security system shift in East Asia. Considering contemporary international conflicts such as U.S.-China strategic competition, Russia-Ukraine War, and growing threats posed by North Korean nuclear and missiles, the study anticipates that the necessity of a collective security system that will replace the current security system of the region would arise. Still, although some issues between countries should be overcome, the growing intensity of the threats will promote cooperation among countries by improving their confidence.

In this study, a place branding model for public library was designed to revitalize public libraries' user visits by modifying and extending the Cai(2002)'s Place Branding Model. By applying this model, an example of creating a brand image of a public library was presented, and it was verified that this example is suitable as a brand image. To this end, literature research on the place branding models and brand marketing was conducted, and the types and contents of marketing suitable for the place branding model of public library were founded. And to verify that the example of the public library's brand image created by applying this model is suitable as a brand image, A survey of user perception was conducted on the brand image and brand identity of the applied library for this model, and the results of the survey were used to analyze the correlation and simple regression between these two variables. In this way, this study is meaningful in increasing the realization and real potential of place branding for promoting public libraries' user visits through the design and application of a conceptual model that embodies the place branding of public library.

The global warming is probably the most significant issue of concern all over the world and according to the report published by the Intergovernmental Panel on Climate Change (IPCC), the average temperature and extent of global warming around the globe have been on the rise and so have the uncertainty for the future. Such effects of global warming have adverse effects on basic foundation of the mankind in numerous ways and water resource is no exception. The researches on water resources assessment for climate change are significant enough to be used as the preliminary data for researches in other fields. In this research, a total of 124 peer-reviewed publications and 57 reports on the subject of research on climate change related to water resources, that has been carried out so far in Korea has been reviewed. The research on climate change in Korea (inclusive of the peer-reviewed articles and reports) has mainly focused on the future projection and assessment. In the fields of hydrometeorology tendency and projection, the analysis has been carried out with focus on surface water, flood, etc. for hydrological variables and precipitation, temperature, etc. for meteorological variables. This can be attributed to the large, seasonal deviation in the amount of rainfall and the difficulty of water resources management, which is why, the analysis and research have been carried out with focus on those variables such as precipitation, temperature, surface water, flood, etc. which are directly related to water resources. The future projection of water resources in Korea may differ from region to region; however, variables such as precipitation, temperature, surface water, etc. have shown a tendency for increase; especially, it has been shown that whereas the number of casualties due to flood or drought decreases, property damage has been shown to increase. Despite the fact that the intensity of rainfall, temperature, and discharge amount are anticipated to rise, appropriate measures to address such vulnerabilities in water resources or management of drainage area of future water resources have not been implemented as yet. Moreover, it has been found that the research results on climate change that have been carried out by different bodies in Korea diverge significantly, which goes to show that many inherent uncertainties exist in the various stage of researches. Regarding the strategy in response to climate change, the voluntary response by an individual or a corporate entity has been found to be inadequate owing to the low level of awareness by the citizens and the weak social infrastructure for responding to climate change. Further, legal or systematic measures such as the governmental campaign on the awareness of climate change or the policy to offer incentives for voluntary reduction of greenhouse gas emissions have been found to be insufficient. Lastly, there has been no case of any research whatsoever on the anticipated effects on the economy brought about by climate change, however, there are a few cases of on-going researches. In order to establish the strategy to prepare for and respond to the anticipated lack of water resources resulting from climate change, there is no doubt that a standardized analysis on the effects on the economy should be carried out first and foremost.

The purpose of this study is to estimate the concentrated distribution area of nutria (Myocastor coypus) and potential suitable habitat and to provide useful data for the effective management direction setting. Based on the nationwide distribution data of nutria, the cross-validation value was applied to analyze the distribution density. As a result, the concentrated distribution areas thatrequired preferential elimination is found in 14 administrative areas including Busan Metropolitan City, Daegu Metropolitan City, 11 cities and counties in Gyeongsangnam-do and 1 county in Gyeongsangbuk-do. In the potential suitable habitat estimation using a MaxEnt (Maximum Entropy) model, the possibility of emergency was found in the Nakdong River middle and lower stream area and the Seomjin riverlower stream area and Gahwacheon River area. As for the contribution by variables of a model, it showed DEM, precipitation of driest month, min temperature of coldest month and distance from river had contribution from the highest order. In terms of the relation with the probability of appearance, the probability of emergence was higher than the threshold value in areas with less than 34m of altitude, with $-5.7^{\circ}C{\sim}-0.6^{\circ}C$ of min temperature of the coldest month, with 15-30mm of precipitation of the driest month and with less than 1,373m away from the river. Variables that Altitude, existence of water and wintertemperature affected settlement and expansion of nutria, considering the research results and the physiological and ecological characteristics of nutria. Therefore, it is necessary to reflect them as important variables in the future habitable area detection and expansion estimation modeling. It must be essential to distinguish the concentrated distribution area and the management area of invasive alien species such as nutria and to establish and apply a suitable management strategy to the management site for the permanent control. The results in this study can be used as useful data for a strategic management such as rapid management on the preferential management area and preemptive and preventive management on the possible spreading area.

There's a trend towards vitalization of nightscape planning businesses nationally and locally as well for city image making and activation of regional economy, but there is still no systematic nightscape planning going on for lack of relevant researches and objective evaluations. This study aims to suggest the guideline for nightscape planning by conducting an eye tracking experiment and survey for recognizing the characteristics of a nightscape. Furthermore, the authors intended to verify the eye-tracking method as a tool for landscape evaluation. The research site was restricted in the campus of Virginia Tech, VA, and those were selected by experts' survey among various types of nightscape images. The variables for analyzing the characteristics of nightscape images selected were 'preference', 'safety(fear)' and 'clearness'. 'Fixation duration', 'saccade duration', 'scan path length', and 'pupil size' were selected as the eye movement measurements. The results of this study are as follows: The first outcome found was that there were significant differences among the characteristics(preference, safety and clearness) of a nightscape by MANOVA, and these variables were correlated positively by Pearson's correlation. Secondly, there were differences on fixation duration, saccade duration and scan path depending on the nightscape setting statistically. Also, the eye tracking measurement in an open setting was recorded lower than enclosed settings. In the result of a heat map, we found the meaning of the fixated areas on both viewing without intention and viewing intentionally. It turned out that the fixated areas were consistent with the areas the subjects felt preferred and clarity in all of the nightscape images, which means people usually focus on what they prefer and see clearly in a certain nightscape. Based on this result and previous studies, the authors could make a conclusion that eye tracking method can apply to evaluate nightscape settings in terms of analyzing the whole characteristics and finding specific points for the detailed analysis as well. Therefore, these results can contribute by suggesting nightscape planning, implication of the landscape evaluation, and implication of the eye tracking study.

The aim of this study is to identify the learning performance of online classes using problem-based learning(PBL) for clothing and textiles majors in college with the increased use of online learning tools after the COVID-19 pandemic. In order to achieve this goal, the PBL was developed and applied to the 'Fashion Marketing and Merchandising' class conducted in real-time online at University in North Chungcheong Province, Korea for four weeks. After a four-week PBL class, a survey was conducted on 35 students in the 'Fashion Marketing and Merchandising' class and the 35 completed questionnaires were used for analysis. The measurement tools of this study were self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement regarded as an important learning effect in PBL class. In addition, students' self-reflective essays were also analyzed to examine the educational effect of PBL applying online classes. As a result of this study, bivariate correlations among the four variables, students' self-directed learning, cooperative learning ability, problem-solving ability, and learning achievement were significantly positive. Furthermore, the results of multiple regression analysis showed that the three independent variables had significant effects on students' perceived learning achievement, in the order of cooperative learning ability, self-directed learning, and problem-solving ability. The students' self-reflective essays indicated that problem-based learning worksheet was helpful for identifying problems, and clarifying what they already and what they need to study more. Based on this study, it could be recommended that online class applying PBL could contribute to the improvement of student's learning performance.

This study examined how specific aspects of epistemic cognition are developed in elementary students during modeling activities, using the Apt-AIR framework. The study focused on a class unit titled 'Shall We Find Out What the Landscape of a Riverside Looks Like?' which is part of the land chapter in the third-grade Korean elementary science curriculum. Ambitious Science Teaching (AST) was applied as a teaching strategy to enhance students' model construction. Seven science classes were conducted in line with the core practices of AST, with 29 elementary school students participating in the study. The classes were organized into four stages: initial model composition, inquiry activity, group model composition-sharing, and final model construction. The class activities at each stage were analyzed using both the AIR model, i.e., epistemic aim and value (A), epistemic ideals (I), and reliable epistemic processes (R), and the multi-faceted framework for epistemic thinking from the Apt-AIR framework. The results of the study revealed that in science classes emphasizing modeling activities based on the core practices of AST, the elementary students progressively developed more sophisticated explanatory models that included causal relationships explaining the topographic differences between the upstream and downstream sections of a river. This result was due to their engagement in constructing initial models to describe phenomena, supplementing the initial models using data collected in the model experiment, and participating in discussions to share and evaluate group models. Additionally, from the perspective of the Apt-AIR framework, the aspects of epistemic cognition demonstrated by the elementary students in their modeling activities were appropriate for engaging with cognitive processes related to epistemic aims and values, epistemic ideals, and reliable processes. The other four aspects of the Apt-AIR framework, however, were not performed as effectively. In particular, the application of reliable epistemic processes for knowledge construction required more improvement.

The consumer's expectation of companies' social responsibilities has been continuously getting higher as the consumerism has been matured. So, the company has faced the shift to move forward to the positive social activity such as charity, donation, and sponsorship. In addition, the company which does make a success needs to reach goals not only to maximize profits but also to make justices of social and cultural boundaries. Thus, success of an enterprise aims at the maximization of profits as the economic objective and the creation of competitive, powerful brands. Accordingly, as enterprises consider social responsibility as the concept of effective investment to enhance the asset value of corporation, they seek to extend their brands in order to pursue cause-related marketing, which accomplishes and complements two objectives each other the performance of social responsibility and the pursuit of powerful brand assets. In Korea, there are traditional ritual ceremonies such as ceremonies of coming-of-age, marriage, funeral, and ancestor worship and they consider those ceremony occasions as very important. Moreover, social positional grade of rank like the two upper classes of old Korea made people pretend to be noble and sensitive to other people around themselves. This old custom could influence Korean people's way of life, especially, consumer-action. This deep rooted custom also could influence consumption life considerably. Through this study, we can understand the consumer behaviors of Korean who consider ritual ceremonies and saving face as essential and are influenced by this culture. on another hand, we intend to check the effects on buying luxury brands.

Flood inundation map has been used as a fundamental information in flood risk management. However, there are various sources of uncertainty in flood inundation mapping, which can be another risk in preventing damage from flood. Therefore, it is necessary to remove or reduce uncertainty sources to improve the accuracy of flood inundation maps. However, the entire removal of uncertainty source may be impossible and inefficient due to limitations of knowledge and finance. Sensitivity analysis of uncertainty sources allows an efficient flood risk management by considering various conditions in flood inundation mapping because an uncertainty source under different conditions may propagate in different ways. The objectives of this study are (1) to perform sensitivity analysis of uncertainty sources by different conditions on flood inundation map using the FOA method and (2) to find a major contributor to a propagated uncertainty in the flood inundation map in Flatrock at Columbus, U.S.A. Result of this study illustrates that an uncertainty in a variable is differently propagated to flood inundation map by combination with other uncertainty sources. Moreover, elevation error was found to be the most sensitive to uncertainty in the flood inundation map of the study reach.
