Recently, much attention has been focused on the change and role of the Arctic region due to climate change. Studies using various platforms are being conducted in the polar regions. Among them, monitoring of Arctic cryosphere information using remote sensing is the most important observational role of various scientific activities. This special issue introduces several studies on polar exploration monitoring in polar research. We hope that this special issue contributes to the sharing of information on the role of polar exploration in remote areas, as well as the identification of the current status of domestic polar exploration and remote environmental exploration. We are also looking forward to the efforts of Korean remote sensing experts to find out the persistent polar exploration field and to increase national support.

South Korea is in a dangerous situation where a war between the two Koreas could be triggered at any time based on the MDL (Military Demarcation Line) between the two Koreas due to the inter-Korean standoff over the armistice. Also, unlike the borders of other countries, the border between the two Koreas is the front-line area where people can feel the threat of life that could be triggered by war. Soldiers who work in special areas such as the contact area are not easily accessible due to local conditions, and are less likely to go out, stay out, stay out, or visit, and the working environment is overloaded with vast forests and silence at night, and feel anxious, lonely and insecure because they don't know when any situation will occur near the enemy. Therefore, a great deal of help will be needed to pay attention to soldiers who give up their lives here and perform their national defense duties, and to finish their barracks life safely and faithfully, and support for psychological adaptation of service members in the border areas.

In the era of the 4th industrial revolution, the big data industry is gathering attention for new business models in the public and private sectors by utilizing various information collected through the internet and mobile. However, although the big data integration and analysis are performed with de-identification techniques, there is still a risk that personal privacy can be exposed. Recently, there are many studies to invent effective methods to maintain the value of data without disclosing personal information. In this paper, a personal information protection system is investigated to boost big data utilization in industrial sectors, such as healthcare and agriculture. The criteria for evaluating the de-identification adequacy of personal information and the protection scope of personal information should be differently applied for each industry. In the field of personal sensitive information-oriented healthcare sector, the minimum value of k-anonymity should be set to 5 or more, which is the average value of other industrial sectors. In agricultural sector, it suggests the inclusion of companion dogs or farmland information as sensitive information. Also, it is desirable to apply the demonstration steps to each region-specific industry.

Local non-timber forest products can be easily accessed by tourists. These also provide opportunities for tourists to experience the local culture. Many local governments are paying constant attention to the development of non-timber forest product brands to revitalize the local economy and increase the profits of local farmers. Although there are many forest products and tourism resources in each region of Korea, there is no local specialized strategy to sell non-timber forest products and promote consumers' purchase intentions. In this study, we aimed to explore the consumers' perceived creating shared value (CSV) and its association with purchasing behavior of non-timber forest products in Jeongeup city, Korea. Data were collected from 1,066 consumers who had purchased non-timber forest products. Purchasing patterns of local specialty products differed depending on consumers' perceived CSV levels. In addition, consumers with higher levels of perceived CSV showed higher awareness and familiarity with Jeongeup city and experienced Jeongeup city's non-timber forest products. Our findings suggest that improving consumer perception towards CSV of non-timber forest products can be used as a marketing strategy for local non-timber forest products to revitalize the local economy.

Background: As the Positive List System (PLS) is implemented in broad application to agricultural products, attention to the correct use of pesticides is also needed in the production of mulberry leaves and fruit. In this regard, three types of pesticides against mulberry popcorn disease were applied 2 - 3 times both in the field and greenhouses to prepare safety standards. Residual pesticide analysis was conducted on mulberry fruits and leaves. Methods and results: Three pesticieds, thiophanate-methyl, thiophanate-methyl·triflumizole and fluopyram registered as PLS pesticides for mulberry popcorn disease, were sprayed in the Wanju and in Buan regions, after which residual pesticide analysis was conducted using high-performance liquid chromatography (HPLC). As three pesticieds were either undetected or below the permissible level in mulberry fruit, demonstrating that they were suitable for safe spraying. However, 5.6 mg/kg of thiophanate-methyl was detected in the greenhouse after three application, which was slightly above maximum residue limit (MRL). Furthermore the level of thiophanate-methyl·triflumizole was higher than 0.2 mg/kg ("Gwasang No. 2" variety, spraying twice) or similar to 0.09 mg/kg ("Daesim" variety, spraying thrice) the permissible level (0.1T mg/kg) as the thiophanate-methyl was detected in mulberry leaves in the greenhouse. Conclusions: The spraying frequency for controlling mulberry popcorn disease in greenhouses should be limited to two times or less, especially when mulberry leaves are treated with thiophanate-methyl·triflumizole careful consideration is required if the leaves are to be used as food materials.

Resting-state Functional Magnetic Resonance Imaging(fMRI) data detects the temporal correlations in Blood Oxygen Level Dependent(BOLD) signal and these temporal correlations are regarded to reflect intrinsic cortical connectivity, which is deactivated during attention demanding, non-self referential tasks, called Default Mode Network(DMN). The relationship between fMRI and anatomical connectivity has not been studied in detail, however, the preceded studies have tried to clarify this relationship using Diffusion Tensor Imaging(DTI) and fMRI. These studies use method that fMRI data assists DTI data or vice versa and it is used as guider to perform DTI tractography on the brain image. In this study, we hypothesized that functional connectivity in resting state would reflect anatomical connectivity of DMN and the combined images include information of fMRI and DTI showed visible connection between brain regions related in DMN. In the previous study, functional connectivity was determined by subjective region of interest method. However, in this study, functional connectivity was determined by objective and advanced method through Independent Component Analysis. There was a stronger connection between Posterior Congulate Cortex(PCC) and PHG(Parahippocampa Gyrus) than Anterior Cingulate Cortex(ACC) and PCC. This technique might be used in several clinical field and will be the basis for future studies related to aging and the brain diseases, which are needed to be translated not only functional connectivity, but structural connectivity.

There was few research dealing with the cultural property or the arts of Southeast Asia before, however many articles and books on the arts of Southeast Asia were published since 2008. There are more than 50 papers dealing Southeast Asian art during the period. It was Vietnamese ceramics and the Buddhist relics of Indonesia which paid attention among those articles. This was relevant to the launching of the Humanities Korea (HK) project by the National Research Foundation in 2007. A study on Southeast Asian arts from each of eleven countries is difficult to achieve outstanding results in a short period of time. Since art historical approach is quite a professional field, the growth of research is limited. Since art historical approach is a professional field, the growth of research is limited. At this point we can say the research on Southeast Asian art are developed in an unbalanced extent in the limited area focused on ceramics and sculptures. Over the past decade, the research on Southeast Asian art has developed, but we still need more experts in specific regions and fields. For establishing the art history as a field of regional studies, it is imperative to cultivate specialists in each region for the profound and balanced understanding the value of Southeast Asian art.

This study aimed to identify the effectiveness of the use of distance-evaluation tools and methods among students with learning difficulties from the teachers' point of view, to achieve this goal. A scale was built, and the psychometric characteristics were validated. It consisted, in its final form, of 17 items distributed on four axes, in addition to three open questions. It was applied to a random sample of (149) teachers of students with learning difficulties in Makkah Region. The results showed that teachers' keenness to encourage students with learning difficulties, so that they would not feel frustrated with the distance learning process. It was also evident that teachers did not use achievement portfolios in the evaluation process. In connection with the appropriate evaluation methods, the majority indicated the use of work sheets and visual evaluation methods that rely on audio and visual skills, such as presenting videos, pictures, audio and games, and applying short objective tests. Among the proposals to improve evaluation methods and tools: Individual evaluation, attention to individual treatment, obligating personal attendance of students to school, splitting the required tasks, and not increasing the skills required to be mastered. As for the obstacles that teachers face: Lack of time, difficulty in communicating with students with distance learning difficulties and problems related to the Internet such as interruption, weakness, or lack of availability.

As an emerging market with rapid economic growth, while being a key region of the K-culture expansion, Vietnam draws increasing scientific attention. This study focuses on the MZ generation, Vietnam's leading consumer group, revealing their consumption value structure. An online survey was used for data collection purposes, investigating 368 Vietnamese consumers between 18-37 years of age. Six value dimensions were derived as results of the present analysis: functional, emotional, social, ethical, self-expression, and autonomy-oriented value. Among them, functional value includes two sub-dimensions of utility and price, while emotional value entails three sub-dimensions, namely hedonism, novelty, and aesthetics. 'Self-expression value' and 'autonomy-oriented value', reflecting the characteristics of the MZ generation, who actively express themselves and respect proactive decision-making, are becoming important standards of the consumption attitude of young Vietnamese. Moreover, the pursuit of 'novelty' was derived as a factor reflecting emotional values, revealing an association between hedonic consumption, and seeking for newness and difference. Furthermore, the relationships between each consumption value dimension, respective demographic characteristics, and global consumption propensity were investigated. The present findings aim to provide insights into young Vietnamese consumers' attitudes and intend to serve as a foundation for future research.
