본 연구는 상업 젠트리피케이션 지역에서 기존 상인(초기진입상인)과 후기진입상인간의 생존율 차이에 대해 비교·분석하였다. 2000년 무렵부터 젠트리피케이션이 진행되어온 홍대 일대 상업지역을 실험군 지역으로 정하고 마포구 내 그 외 상업지역을 대조군 지역으로 설정하여 초기 및 후기진입 상인 간의 생존율 차이를 업종별로 검토하였다. 아울러, 프랜차이즈업과 비프랜차이즈업의 소유구조에 따라 실험군과 대조군 지역에서 생존율의 차이 유무에 대해서도 분석하였다. 분석결과, 홍대 젠트리피케이션 지역에서는 요식업, 카페및베이커리업, 유흥업 전반에 걸쳐 기존 상인의 생존율이 후기진입상인에 비해 낮은 것으로 밝혀져 '기존상인 이탈현상' 가설을 증명하였다. 반면 대조군 지역에서는 두 그룹간 생존율 차이는 크지 않았으며 근린상업의 경우 기존 상인의 생존율이 후기진입상인보다 높은 것으로 확인되어, 젠트리피케이션 상권과는 확실하게 대별되었다. 프랜차이즈점의 경우 홍대 앞 상권이나 대조군 상권에서 모두 비프랜차이즈 업체보다 생존율이 높음을 확인할 수 있었다. 다만, 프랜차이즈점만을 비교할 경우 영업 3년차까지는 홍대 앞 상권에 위치한 프랜차이즈점이 생존확률이 더 높았지만, 영업 3년 이후에는 대조군 상권에 위치한 프랜차이즈점의 생존확률이 더 높은 결과를 보인다. 이는 프랜차이즈의 이점이 시장 변화가 급속한 젠트리피케이션 환경에서 오랫동안 유지될 수 없음을 암시하고 있다. 본 연구는 젠트리피케이션 지역에서 기존 상인의 이탈과 생존환경의 불리함에 대한 다양한 가설 및 일화적 스토리를 보다 체계적이고 정량적으로 검증하였다.

Aspergillus oryzae is generally recognized as safe, but it is closely related to A. flavus in morphology and genetic characteristics. In this study, we tested the aflatoxigenicity and genetic analysis of nine commercial A. oryzae strains that were used in Korean soybean fermented products. Cultural and HPLC analyses showed that none of the commercial strains produced detectable amount of aflatoxins. According to the molecular analysis of 17 genes in the aflatoxin (AF) biosynthetic pathway, the commercial strains could be classified into three groups. The group I strains contained all the 17 AF biosynthetic genes tested in this study; the group II strains deleted nine AF biosynthetic genes and possessed eight genes, including aflG, aflI, aflK, aflL, aflM, aflO, aflP, and aflQ; the group III strains only had six AF biosynthetic genes, including aflG, aflI, aflK, aflO, aflP, and aflQ. With the reverse transcription polymerase chain reaction, the group I A. oryzae strains showed no expression of aflG, aflQ and/or aflM genes, which resulted in the lack of AF-producing ability. Group II and group III strains could not produce AF owing to the deletion of more than half of the AF biosynthetic genes. In addition, the sequence data of polyketide synthase A (pksA) of group I strains of A. oryzae showed that there were three point mutations (two silent mutations and one missense mutation) compared with aflatoxigenic A. flavus used as the positive control in this study.

In 2003, the Uniform Commercial Code(UCC) which is a kind of model law to unify commercial law between several states in US was amended to use electronic document of title including bill of lading. It is the second following the Australia legislation in 1996. Also, the Korean government amended Commercial Act and made the Presidential Decree for using electronic bill of lading in 2008. In this paper the authors reveal the characteristics of the clause of UCC for electronic bill of lading. The characteristics of the clause are on the technical neutrality of the signature, the possibility of reissuance in alternative medium, and adoption of the concept of "control." It helps to suggest some implications for Korean government authority. The authors suggest the amendment of the Presidential Decree to the Korean government authority to use additionally digital signature authorized by non Korean government such as VeriSign. It will activate the use of electronic bill of lading issued by Korea repositary out of Korea.

For commercial vehicles with a manual transmission, the pneumatic and fluid pressure servo-device is widely used for transmitting large torque. However, the pneumatic and fluid pressure servo-device usually results in non-linear variation of foot-efforts, also such characteristics tend to increase physical fatigue of drivers who drive commercial vehicles for a long time. Thus, vehicle manufacturers consider the hysteresis loops in the Clutch Actuation System (CAS) design when a new vehicle model is being developed. In this study, we numerically simulate the hysteresis loops for predictable CAS design, and the experimental results confirm the simulation results.

Objective: The purpose of this study is to define consumers' affection on the interior design of commercial cars in terms of its design factors: color, embossing and gloss as independent factors. Background: Existing affective studies related to interior of vehicle focus on just sedans. However, there is no affective study about the interior of commercial cars. In addition, it is hard to change levels to which manufactures want. Method: Representative design factors were drawn using ANOVA and SNK analysis and definitive affective vocabularies were drawn using factor analysis. Furthermore, the results of 3D experiment were analyzed using ANOVA and LSD analysis. 3D images for the experiment were made using 3D max program. The experiment revealed that consumers discerned the differences in levels of each design factor and affective vocabulary. Results: The ANOVA revealed that beige color "A" type and non-gloss were the most preferred design in terms of the affective vocabularies and total preference. Conclusion: The result of the experiment may help manufactures to design the interior of commercial cars in the near future. Furthermore, the ANOVA result of affective vocabularies evaluation is expected to suggest a meaningful guideline. Application: The study results may be utilized as a guideline for interior design of commercial cars.

The purpose of the research to evaluate the efficiency and productivity growth rate of some Vietnamese commercial banks in the period 2008-2020. Using input and output selection theory, the author selected 2 models, estimating the efficiency for model 1 and estimating the yield change for both the models. We have built a model to estimate the efficiency and calculate as well as decompose the productivity growth of Vietnamese commercial banks during the period of active mergers and acquisitions activities in the banking system. Based on the results of the efficiency estimation, TFP shows during mergers and acquisitions, efficiency fluctuates but in an inverted U-shape (increasing from 2008-2011 but decreasing from 2013 to 2020). The estimated results of the impact assessment model show that FDI reduces the efficiency of banks. Productivity analysis shows that 6 out of 23 banks in the study period had positive TFP growth (tfpch > 1) due to technical progress and management efficiency. The findings of this study suggest that Vietnam's commercial banking system has many opportunities to improve operational efficiency in many aspects. In which, there are opportunities to increase credit, improve governance as well as improve the technology level of each bank. In addition, along with traditional products such as deposits and loans, diversification with a wide range of products and services is an important factor to enhance customer experience and demand in commercial banks.

In the past, the analog protection relays have been widely used for the safety-related systems in the nuclear power plants due to their stability and reliability. Meanwhile, as the high performance digital system has been developed, the digital systems have been adopted in the non-safety systems. However, since the digital systems currently used in the non-safety systems were not developed according to Q-class standard, Commercial Grade Item Dedication (CGID) procedure should be performed in order to apply them to the safety-related system. The purpose of this paper is to describe the CGID procedure including the analysis of the hardware architecture as well as the software embedded in protective relay to apply to the emergency diesel generator in the nuclear power plant. The entire CGID procedure was performed strictly according to the international standard and regulations.

The aim of the present study is to analyze the financial performance of converted commercial bank from non-banking financial institution through a case study of Bangladesh Commerce Bank Limited as sample organization. It is observed that the bank is able to achieve a stable growth rate in total deposits, total loans and advances, and net income after tax during the period of 2015-2019. Researchers also calculated some ratio analysis and noticed that the financial position of Bangladesh Commerce Bank Limited was not so strong because bank's ROA, ROE, NIM and other ratios were below standard. Researchers used secondary data that were examined by using descriptive statistical tools and panel data regression model. Result shows that Bangladesh Commerce Bank has satisfactory operating efficiency, assets management efficiency, and gives loans to customers. In addition, the present study has tested some hypotheses regarding net income after tax, ROA and ROE with total assets, total loans, total deposits and interest income. These hypotheses have been accepted, which means there is no significant influence of the independent variable on the dependent variable. The study suggests that Bangladesh Commerce Bank Limited had the opportunities to make their financial position stronger by utilizing their good financial position and management efficiencies.

This study aims to investigate the impact of the multimarket contract on risk-adjusted profitability. Risk-adjusted profitability is measured in terms of risk-adjusted return on assets. This study employs dynamic panel data of 27 commercial banks in Vietnam using the GMM estimator to test the multimarket contact hypothesis in the Vietnamese banking sector. The results show that there is a negative impact of multimarket contact on the profitability of banks. Multimarket contact, deposit to asset ratio, non-interest income to total income, GDP growth rate, Worldwide Governance Indicator (WGI), and operating cost to assets are the major determinants of risk-adjusted profitability of commercial banks. Our main findings show that Vietnamese banks' focus to increase the multimarket contact may lead to lower profitability and there is evidence that supports theory predictions, since the average number of contacts among banks, bank size, and capitalization are positively related to risk-adjusted profitability. The study has policy implications for commercial banks in that they should not only focus on interest as a source of income and diversify their income source from non-interest income as well since it helps to improve risk-adjusted profitability for them.
