The relationship between adult abundance and zoea I (ZI) density of Dungeness crabs was investigated in southeastern Alaska. Commercial harvest data (catch per pot) for male crabs larger than 165 mm in carapace width were collected from the Alaska Department of Fish and Game (ADF&G) management area, district 114 and a subdivision of district 114, 114C from 1996 to 2003. Commercial harvests of Dungeness crabs in the management area varied interannually. Commercial harvests decreased until 2000 but increased beginning in 2001. ZI density was obtained from zooplankton samples collected monthly from sampling stations within the same management district from 1997 to 2004. ZI occurred mostly in May and June, but as late as July in 1997 and 2002. ZI densities increased beginning in 1999. Total densities of ZI were significantly correlated with the commercial harvest data of adult male crabs within the management area, 114C (tens of square kilometers), containing the plankton sampling stations, but were not related to total commercial harvests within the larger geographic management area 114 (hundreds of square kilometers). We suggest that larval density may be an indicator of abundance of adult populations of Dungeness crabs.

The purpose of this study is to examine the effects of credit risk on commercial banks' profitability in Afghanistan. Due to the availability of limited data, this study applies the Fixed Effects estimator on balance panel data of six domestic private commercial banks over the period 2014-2018. The study uses LLRTL, TLTA, and TLTD as credit risk indictors, size as bank-specific determinant, ROAA, ROAE, and NIM as profitability indicators. The study finds a robust negative and significant effect of LLRTL on ROAA, and ROAE, but positive and insignificant on NIM. The results also reveal significant positive effect of TLTA on NIM, however insignificant negative on ROAA while insignificant positive on ROAE. The study finds negative effect of TLTD on ROAA, ROAE, and NIM, but only significant on NIM. Further, this study reveals a robust negative and significant effect of size on all profitability indicators. The mean comparison of profitability demonstrates that NIM is in a better situation than others profitability indicators, which is a good sign for the Afghan banking sector. The findings of this study suggest that improving credit management, increasing efficiency of asset management or effectiveness of business model can increase commercial banks' profitability in Afghanistan.

In this paper, the purpose is to create a standard of AI training dataset type for commercial space design. As the market size of the field of space design continues to increase and the time spent increases indoors after COVID-19, interest in space is expanding throughout society. In addition, more and more consumers are getting used to the digital environment. Therefore, If you identify trends and preemptively propose the atmosphere and specifications that customers require quickly and easily, you can increase customer trust and conduct effective sales. As for the data set type, commercial districts were divided into a total of 8 categories, and images that could be processed were derived by refining 4,009,30MB JPG format images collected through web crawling. Then, by performing bounding and labeling operations, we developed a 'Dataset for AI Training' of 3,356 commercial space image data in CSV format with a size of 2.08MB. Through this study, elements of spatial images such as place type, space classification, and furniture can be extracted and used when developing AI algorithms, and it is expected that images requested by clients can be easily and quickly collected through spatial image input information.

본 연구는 젠트리피케이션이 발생한 상권의 장소성을 파악하여 상권의 확장과 쇠퇴 속에서 장소성의 구체적인 모습을 유형화하고 유형별 특징을 분석하는 것을 목적으로 한다. 소셜 미디어를 통해 수집된 대용량 문서를 활용하여 위계적 군집분석을 시행하였으며, 지역별 장소성을 인지적 차원의 <경험>과 실재적 차원의 <상권특성>으로 구분하여 상권 군집별 특성을 확인하였다. 이를 위해 잠재 디리클레 할당(Latent Dirichlet Allocation: LDA) 토픽모델링 기법과 서울시 우리마을가게 상권분석서비스를 통해 수집된 상권별 매출액 통계자료를 활용하였다. 분석 결과 서울시 젠트리피케이션 상권은 고유한 특성을 가진 '연극 상권', '전통문화 상권', '여성 미용 상권', '고급음식점 및 의료서비스 상권', '트렌디 상권'으로 분류되는 것으로 나타났다. 연구의 결과를 바탕으로 보다 효율적이고 지역별 특색에 맞는 상업정책들을 시행할 수 있을 것으로 기대한다.

Big data information and pattern analysis have applications in many industrial sectors. To reduce energy consumption effectively, the eco-driving method that reduces the fuel consumption of vehicles has recently come under scrutiny. Using big data on commercial vehicles obtained from digital tachographs (DTGs), it is possible not only to aid traffic safety but also improve eco-driving. In this study, we estimate fuel consumption efficiency by processing and analyzing DTG big data for commercial vehicles using parallel processing with the MapReduce mechanism. Compared to the conventional measurement of fuel consumption using the On-Board Diagnostics II (OBD-II) device, in this paper, we use actual DTG data and OBD-II fuel consumption data to identify meaningful relationships to calculate fuel efficiency rates. Based on the driving pattern extracted from DTG data, estimating fuel consumption is possible by analyzing driving patterns obtained only from DTG big data.

Earnings management behavior is the use of accounting procedures, through accounting policies, to intentionally purposeful control in the provision of information to users. The purpose of this paper is to examine the relationship between ownership structure factors and earnings management behavior of 30 Vietnamese commercial banks. The paper uses the ordinary least square method to examine this relationship and employs time series data of 15 years from 2005 to 2019. The study also uses agency theory an asymmetric information theory. The authors examined six independent variables related to the ownership structure and these variables are typical of Vietnamese commercial banks. The results of the study show that the foreign ownership ratio is an opposite effect, while the ownership concentration variable has a positive effect on earnings management behavior of Vietnamese commercial banks. Based on that, the article proposes a number of policy suggestions for the State bank of Vietnam and Board of directors of commercial banks as well as investors to identify and to limit the earnings management behaviors of Vietnamese commercial banks. This contributes to ensuring information transparency as well as improving the quality of accounting information of Vietnamese commercial banks in the coming years.

Sik-hae is a traditional and well-liked salt-fermented seafood with a low salt concentration in Korea. However, it is challenging to find data on market degradation. This study was conducted to investigate sensual characteristics, such as taste, odor and color, of 10 types of commercial Sik-haes [flounder (5 type), Alaska pollock (2 type), black edged sculpin, anchovy, and sandfish] as basic data for developing new products. The salinities of the commercial Sik-haes were significantly difference in the range of 3.0-6.7%. The pH and total acidity of 10 types of commercial Sik-haes were 4.45-5.24 and 0.84-1.46 g/100 g, respectively. The amino acid nitrogen and free amino acid contents, and total taste value were 72.0-333.0 mg/100 g, 425.6-1,726.4 mg/100 g and 17.0-115.9, respectively. According to the taste value, the major taste-related amino acids were aspartic acid and glutamic acid. Volatile basic nitrogen content and Hunter redness value of commercial Sik-haes were 24.5-80.9 mg/100 g and 10.9-28.5, respectively. However, food-grade additives, such as citric acid and monosodium, are occasionally used in commercial Sik-haes to achieve a lower pH or enhance flavor and aroma.
