Research papers in the field of atmospheric environment published in three Journals: Journal of Korean Meteorological Society, Atmosphere, and Asia-Pacific Journal of the Atmospheric Sciences, are all summarized over period of 60 years since the establishment of Korea Meteorological Society (KMS) in 1963. In addition, current research trends and future outlook in the atmospheric environment field has been also highlighted. The results of historical records published in three KMS journals indicated that the activities, contents, and scope of researches carried out by KMS members in the field of atmospheric environment have yielded the enormous and rapid progress in each of the all four areas over 60 years. In particular, as the chronological progress of observational instruments and availability of satellite data such as from GEMS can be a great asset to deepen the observational and modeling researches in the current and future studies, it is highly anticipated that the more progressive and in-depth studies can be achievable to abate the air pollutants over the Korea as well as northeast Asia.

The six-year (2000~2005) record of aerosol optical thickness (AOT or $\tau$) data from the Moderate Resolution Imaging Spectroradiometer (MODIS) was analyzed over the Northeast Asia. The MODIS AOT standard products (MOD04_L2) over both ocean and land were collected to evaluate the spatial and temporal variability of the atmospheric aerosols over the study region ($32^{\circ}N{\sim}42^{\circ}N$ and $115^{\circ}E{\sim}133^{\circ}E$). The monthly averaged AOT result revealed slight changes(${\pm}0.002{\tau}/month$), which was almost unchangeable, over Korea. In contrast, the large AOT values (> 0.6) and a significant AOT increase (> 0.004 ${\tau}/month$) over East China were observed. For the analysis of spatio-temporal variability of AOT values, study area was divided by six sectors (I: North-East China, II: East China, III: Yellow Sea, IV: Korea Peninsular, V: East Sea, and VI: South Sea and Western part of Japan). The considerable result showed that particularly high AOT contribution was observed over sector I (32.5%) and II (25.5%) where some major urban and industrialized areas and agricultural fields are located and other cases were observed 13.2%, 14.6%, 7.1%, 7.0% over sector III, IV, V, and VI, respectively. In addition, yearly AOT changes based on seasons are observed differently at each sector but increasing trends reveal in summer and fall over all sectors.

This study compares and contrasts the intellectual development of the MIS field in Korea from 2005 to 2009 to that of international trends by using a keyword co-occurrence network analysis of the two flagship journals: APJIS and MIS Quarterly. From 316 research articles in these two journals, 132 unique and most frequently co-occurred keywords were put into analysis. The results of structural equivalence show a mild correlation between APJIS and MIS Quarterly. The e-commerce, trust, and technology adoption are the high frequency keywords in both journals. In Korea e-learning, purchasing, and recommendation systems turn out to be important keywords while outsourcing, research method, quantitative method, design research, information theory, and empirical research are in average international journals. This connotes that the Korean scholarship tends to focus more on practically oriented topics, but the clustering and relational mapping of research topics in each journal show a mild level of overlap with distinctive orientations due to intrinsic disparities depending on the concerned journals' geographical scopes, namely domestic or global.

Objectives: The objective of this study was to perform a scoping review to describe clinical study trends on Qigong in order to identify further directions of Qigong in Korean medicine. Methods: Under the Arksey and O'Malley methodological framework, PubMed was searched to identify articles published from January 1, 2019 to June 28, 2021. A total of 224 articles were retrieved. Results were systematically filtered by two independent reviewers based on inclusion/exclusion criteria. Publication information, disease, intervention and research results of a total of 153 articles were extracted and analyzed. Results: Asia had the largest number of Qigong studies (82 studies, 65%). Most research studies were conducted in the academic field of Medicine (n=109, 86.5%), including Complementary and Alternative Medicine (n=35), Medicine (miscellaneous) (n=15), and Oncology (n=15). Based on ICD-10 classification, Mental and Behavioral Disorder (n=25, 19.8%) was the most frequently analyzed decease, followed by Neoplasm (n=24) and Disease of the Nervous system (n=12). Almost half of all studies were Systematic Reviews. RCTs only accounted for 25.4%. Interventions were very diverse and inconsistent. Sixty (47.6%) studies analyzed Qigong as a single intervention. In 66 cases, Qigong was analyzed as part of a large category such as Mind-Body intervention. Most studies designed a Donggong (動功) program. The age of the population was relatively high as 47.1% of all studies were conducted on middle aged or older adults. Conclusions: These findings suggest that further standardized research on Qigong, especially Junggong (靜功), needs to be conducted by developing research protocols and practice programs to verify effects of Qigong and utilize Qigong as a medical intervention in Korean Medicine.

In the 21st century, both globalization and e-Transformation trends of business in China have been in progress simultaneously and very rapidly. Due to those phenomena, there is consequently big change not only in the field of political-economy but also in the cultural trend of the world. But, despite of the importance of mutual cooperation between Korea and China, the research about Chinese cyber culture is neglected relatively. The purpose of this study is to review the cyber cultural aspect of business between two countries, and to devise proper measures for cultural cooperation not only reengineering the role of two countries but developing mutual benefit in East Asia in the era of global competition. The methodology used in this study is basically depending on theoretical study. Major findings are as follows: China has some cyber-cultural characteristics like very big size of netizen, heaven on earth of counterfeit, deepening in digital divide, etc. And Chinese traditional off-line culture has changed as the cyber culture spreaded over in cyberspace recently. But, on the other hand, cultural trends are changed to homogeneity both in nation-side which is between Korea and China and in space-side which is between online and offline culture. It is recommended that Korea and China have to endeavor to understand mutual culture, and to utilize the cyber culture in the respect of business cooperation. Consequently, two countries should effort to prepare exchange program for both netizen group, to design culture-networking system, to strengthen cyber-cultural marketing, and to make good use of both Korean Cultural Wave(said Han-Ryu) and Chinese Cultural Wave(said Hwa-Ryu).

Dual-bell nozzle can overcome the performance losses of the conventional bell-shaped nozzles which induced by off-design operations with either over-expanded or under-expanded exhaust flow and minimize the losses of the specific impulse. In United States, Rocketdyne analyzed thrust characteristics according to the shape of the expansion nozzle and NASA conducted hot firing tests with various altitudes. DLR, which is one of the research institute of the Europe, is carrying out research for the different cases of inflection angle, nozzle length and expansion ratio. MAI of Russia applied the slot nozzle to the expansion region in order to reduce the performance losses. In Asia, both the Japan and the India are researching on the dual-bell nozzle and Mitsubishi cooperation of the Japan registered its patent. In this paper, concepts and performance of dual-bell nozzle, which can compensate altitude, are investigated and trends of current research are summarized. It is necessary for Korea to research on the dual-bell nozzle for lucrative space development.

Recent research shows that since the early 2000s, the Chinese Communist Party has increasingly used various cultural heritage sites, including Buddhist sites, as soft power agents. Furthermore, in the context of the Belt and Road Initiative, launched by the People's Republic of China, Buddhist temples, representatives, and practices have been harnessed to play a role in the state's agenda. In this context, White Horse Temple, as a feature of cultural tourism in Henan Province, is facing new opportunities and challenges. The article examines the material particularities of reconstructing the temple in light of this trajectory, building on materials retrieved at the site, and online representations of the temple. The author explores how the temple's unique spatiality and characteristics stress the use of soft power which harnesses online and offline cultural and popular trends for state agenda.

Americans continue to have beliefs in the paranormal, for example in UFOs, ghosts, haunted houses, and clairvoyance. Yet, to date there has not been a systematic gathering of data on popular beliefs about the paranormal, and the question of whether or not there is a convincing trend in beliefs about the paranormal remains to be explored. Public opinion polling on paranormal beliefs shows that these beliefs have remained stable over time, and in some cases have in fact increased. Beliefs in ghosts (25% in 1990 to 32% in 2005) and haunted houses (29% in 1990, 37% in 2001) have all increased while beliefs in clairvoyance (26% in 1990 and 2005) and astrology as scientific (31% in 2006, 32% in 2014) have remained stable. Belief in UFOs (50%) is highest among all paranormal beliefs. Our findings show that people continue to hold beliefs about the paranormal despite their lack of grounding in science or religion.

Asian food and the Asian restaurant market have grown rapidly in the international market. It has become one of the major trends in the restaurant industry in the world. However, there has been little attempt to develop a scale for measuring customer's motivation to experience Asian restaurants, and cross-cultural approaches are very rare. From this point of view, this study examined an instrument to measure motivation to visit Asian restaurants developed by Jang and Kim (2015), which was originally developed based on UK customers, by applying the population from another cultural background, Thailand. A total of 308 valid responses were obtained in Thailand. CFA was performed with a Thai sample to test internal and external consistency of the scale with another population, and a comparison was made between UK and Thai customers.

The characteristics of heat wave events in Seoul are analyzed using weather station data from Korea Meteorological Administration (KMA) and European Centre for Medium-Range Weather Forecast (ECMWF) ERA-Interim reanalysis data from 1979 to 2016. Heat waves are defined as events in the upper 10th percentile of the daily maximum temperatures. The associated synoptic weather patterns are then classified into six clusters through Self-Organizing Map (SOM) analysis for sea-level pressure anomalies in East Asia. Cluster 1 shows an anti-cyclonic circulation and weak troughs in southeast and west of Korea, respectively. This synoptic pattern leads to southeasterly winds that advect warm and moist air to the Korean Peninsula. Both clusters 2 and 3 are associated with southerly winds formed by an anti-cyclonic circulation over the east of Korea and cyclonic circulation over the west of Korea. Cluster 4 shows a stagnant weather pattern with weak winds and strong insolation. Clusters 5 and 6 are associated with F?hn wind resulting from an anti-cyclonic circulation in the north of the Korean Peninsula. In terms of long-term variations, event frequencies of clusters 4 and 5 show increasing and decreasing trends, respectively. However, other clusters do not show any long-term trends, indicating that the mechanisms that drive heat wave events in Seoul have remained constant over the last four decades.
