KMA successfully began to receive and utilize the GOES-9 GVAR data since May 22nd 2003 when GOES-9 replaced the long-lived GMS-5 for Western Pacific and East Asian region until operation of MTSAT-1R in 2004. To take advantage of improvements of the GOES-9 data over the GMS-5 data, such as the increase of the temporal and spat ial resolution and addition of 3.9${\mu}$m channel, we have improved several algorithms to derive the meteorological products. Here we show two examples of algorithms, sea surface temperature and atmospheric motion vector, and preliminary results of validation of the improved algorithm.

The study investigates the relationship and influence between religiosity, reward, and engagement in the public administration sector, both directly and causally via moderation. This study involved one hundred and twenty-three respondents in three local government organizations in Malang City, East Java Province, Indonesia, namely, the Malang City General Hospital, the Population and Civil Registry Office, and the Investment Office. The sampling method uses stratified random sampling from the total population of civil servants in Malang in the three institutions. The data analysis model of this study uses a quantitative approach with a unit of data analysis using the path analysis method. The analytical tools used are smart-PLS and SPSS. The results reveal that the direct combined effect of reward and religiosity has a positive and significant influence on the engagement. However, moderation between reward and commitment, which is bridged by religiosity, does not show positive and significant results. The non-positive relationship shown by testing moderation concludes that there is a separation of purpose between the portion of religiosity in the world of work, where religiosity in this study is only described as part of the concept of worship, and the relationship between the person and his God.

In order to assimilate MHS satellite data into the convective scale model at KMA, ATOVS data are reprocessed to utilize the original high-resolution data. And then to improve the preprocessing experiments for cloud detection were performed and optimized to convective-scale model. The experiment which is land scattering index technique added to Observational Processing System to remove contaminated data showed the best result. The analysis fields with assimilation of MHS are verified against with ECMWF analysis fields and fit to other observations including Sonde, which shows improved results on relative humidity fields at sensitive level (850-300 hPa). As the relative humidity of upper troposphere increases, the bias and RMSE of geopotential height are decreased. This improved initial field has a very positive effect on the forecast performance of the model. According to improvement of model field, the Equitable Threat Score (ETS) of precipitation prediction of $1{\sim}20mm\;hr^{-1}$ was increased and this impact was maintained for 27 hours during experiment periods.

This study examined the impact of assimilating the bending angle (BA) obtained via the global navigation satellite system radio occultation (GNSS RO) of the three new satellites (KOMPSAT-5, FY-3C, and FY-3D) on analyses and forecasts of a numerical weather prediction model. Numerical data assimilation experiments were performed using a three-dimensional variational data assimilation system in the Korean Integrated Model (KIM) at a 25-km horizontal resolution for August 2019. Three experiments were designed to select the height and quality control thresholds using the data. A comparison of the data with an analysis of the European Centre for Medium-Range Weather Forecasts (ECMWF) integrated forecast system showed a clear positive impact of BA assimilation in the Southern Hemisphere tropospheric temperature and stratospheric wind compared with that without the assimilation of the three new satellites. The impact of new data in the upper atmosphere was compared with observations using the infrared atmospheric sounding interferometer (IASI). Overall, high volume GNSS RO data helps reduce the RMSE quantitatively in analytical and predictive fields. The analysis and forecasting performance of the upper temperature and wind were improved in the Southern and Northern Hemispheres.

디지털전환과 AI·데이터시대가 심화되면서 데이터의 원활한 흐름과 활용을 위한 데이터 정책, 그리고 그 의사결정 구조로서의 데이터 거버넌스에 대한 관심이 증대되고 있다. 기존의 데이터 거버넌스 연구들을 살펴보면, 데이터 거버넌스 자체의 측정이나 사례 분석은 많이 이루어지고 있으나 실증연구가 부족한 것으로 보인다. 이 논문에서는 데이터 거버넌스의 구성요소 간 구조적 관계와 그것이 목표로 하는 데이터 융합이나 데이터기반행정 등에 미치는 영향을 실증하고자 하였다. 첫째, 데이터 거버넌스에 대한 다양한 정의와 구성요소 및 유형화의 방식, 이를 적용한 선행연구들을 살펴보고, 공공 부문에 특화된 데이터 정책 관점의 정의를 개발하여 적용하였다. 둘째, 분석틀과 가설을 설정하고, 검증을 위해 한국행정연구원의 '공공데이터 정책 활용 실태조사' 자료를 분석하였다. 분석 결과, 데이터 거버넌스 구성요소 중 조직 요소가 제도 요소와 기술 요소 사이에서 매개적 효과를 나타내었고, 제도 요소와 기술 요소가 데이터 융합이나 데이터기반행정에 통계적으로 유의한 긍정적 영향을 미치는 것으로 나타났다. 셋째, 데이터 거버넌스에서 법제도의 개선과 개발에 대한 관심과 투자, 데이터 기술의 수단과 목적에 대한 명확화, 데이터 조직과 인력에 대한 관심과 실제적으로 작동할 수 있는 메커니즘의 개발 등, 몇 가지 중요한 정책적 시사점을 제시하였다.

The improvement and richness of research in a particular domain are fundamentally based on their own various research topics and scientific or systematic research methodology. Especially considering fisheries business administration as a branch of business administration, the interdisciplinary concept will be a important factor in the research of fisheries business administration. This study analyzes fisheries business administration research through bibliometric analysis and meta-analysis to examine meta-data including research trends, researcher characteristics, and keywords. The 225 source articles are all papers published from 1990 to 2006 in the Journal of Fisheries Business Administration Society of Korea. Comparing previous research from the 80s, the major areas of Korean fisheries business administration research have changed and the rate of co-researched papers has also increased. In keyword-based meta-analysis, the topics of recent research are well balanced and diversified but some structural and editorial problems still remain. The result from meta-data and bibliometric information gathered in this study will help create guidelines for carrying out further rigorous research and enhancing the quality of research in fisheries business administration.

The Studying is on developing precision of the moisture information on a soil. We used the data of AQUA AMSR-E which were obtained by Direct Receiving System in Korea Meteorological Administration(KMA). Although we know the Soil Moisture Information(SMI) helps the numerical weather model to produce the realistic results, we couldn't do it for the problem on a spatial resolution of the data is too low to apply. So we've tried to develop in a spatial resolution by using the AMSR-E data with a Digital Elevation Model(DEM) and Normal Difference Vegetation Index(NDVI) from AQUA MODIS and compared the difference between their information in statics. The result is more precise than the simple algorithm by a polarization ratio, and we could get the better result to use in forecast practically, if it's apply to get more detail in the vegetation temperature.

Purpose: The is study aimed to examine the impact of consumer ethnocentrism on reasoned action and brand equity on Generation Z in Vietnam. Research design, data and methodology: A quantitative study was undertaken on 302 Generation Z members. The data for the study was collected using a Google Form-based questionnaire from December 2021 to January 2022. Descriptive statistics, Cronbach's alpha, and structural equation modeling were among the data analysis techniques employed. The results: The results show that consumer ethnocentrism has a direct positive impact on reasoned action (subjective norms and attitude toward domestic goods) as well as an indirect positive impact on brand equity, including brand awareness, brand quality, and brand image. Major findings: According to the findings of this study, governments should continue to push propaganda and advocacy programs, call for national pride and encourage home consumers to support and use domestic goods. Domestic brands must strengthen their ties to the community and invest in community-oriented programs that promote domestic consumption. Vietnam's domestic fashion brands need to promote the exploitation of community-oriented and nationalistic content to call on domestic consumers to support them to consume domestic brands.

빅데이터의 가치가 인식되고 정부 3.0이 발표되면서 빅데이터에 대한 관심이 증가하고 있다. 그러나 각 부처나 지방자치단체에 구체적인 추진 대안이나 전략이 취약한 상황에서 빅데이터를 체계적으로 활용하고 성과를 낸다는 것은 그리 쉬운 일이 아닐 것이다. 이에 본 연구는 지방자치단체의 빅데이터 활용 영역을 정리한 다음, 빅데이터 활용 전략을 제안하고자 하였다. 연구 결과 지방행정의 빅데이터 활용 영역은 크게 이상 현상 감지 및 대응, 가까운 미래 예측 및 대응, 분석된 상황 대응 및 새로운 정책(행정 서비스) 개발, 시민 맞춤형 서비스 등 네 가지로 구분되었다. 또한 빅데이터 활용 전략은 단계적 접근, 사용자의 요구분석, 주요성공요소 기반 추진, 시범사업, 성과평가, 성과에 따른 인센티브, 공통기반 구축 등으로 정리하였다.
