Purpose: The purpose of the study is to explore the factors which influence the night-time economic development in Hanoi, Vietnam. The results can help policymakers achieve a scientific basis to plan the development of night-time economy in Hanoi. Research design, data and methodology: The research model is developed from literature review with 7 independent variables, including natural conditions and resources, infrastructure, safety, environmental issues, promotion and international integration, development of sharing economy, and institution and policy. This model is then adjusted by exploratory factors analysis to have 4 new variables: Institution and environment, Infrastructure and safety, Promotion and sharing, and Nature and resources. The model is regressed based on the data of 463 observations of night-time economy in Hanoi, Vietnam. Results: Consistent with the current literature addressing night-time economy, the results show positive impacts of all of the independent variables studied. Conclusions: It is recommended for the local authorities to strengthen advertising and promoting investment for NTE development in Hanoi city and also enhance the role of state management in NTE activities by raising awareness of the state management apparatus towards a more open-minded multi-dimensional view of the NTE, developing the NTE to overcome the barrier of thinking "if it cannot be managed, it is forbidden" in state management agencies, and defining responsibilities and authority among state management agencies in the management of NTE activities and strengthening decentralization and decentralization of powers for localities in the management and development of NTE.

화학적 방법에 의한 NTE graphite의 박리 또는 전도도 개선을 위한 도핑공정을 수행할 경우, 결함 및 불순물 생성에 의해 재결정화 공정 및 순도 개선을 위한 별도의 공정을 필요로한다. 본 연구에서는 건식 방법으로써 10,000K 이상의 초고온 RF 열플라즈마를 이용하여 in-situ 방법으로 흑연의 박리, 결함 제거, 결정성 향상 및 도핑 공정을 수행하고, 도핑특성을 평가하였다. 질소 도핑을 위하여 암모니아 가스를 첨가하여 NTE graphite를 도핑 처리하였으며, 시뮬레이션을 통하여 반응기 내부의 온도분포를 파악하고, 도핑을 위한 암모니아가스가 분해되어 도핑공정이 수행될 수 있는 투입위치를 결정하였다. 질소 도핑율은 암모니아 가스의 주입위치에서의 온도 및 가스 주입 유량 등의 공정조건에 따라 변화됨을 확인하였고, XPS 분석결과 최대 14.87 atomic%의 도핑율의 결과를 얻었다.

Objectives Sasang constitutional medicine is a traditional Korean medicine that classifies humans into four constitutions in consideration of individual differences in physical, psychological, and physiological characteristics. In this paper, we proposed a method to classify Taeeum person (TE) and Non-Taeeum person (NTE), Soeum person (SE) and Non-Soeum person (NSE), and Soyang person (ST) and Non-Soyang person (NSY) using a convolutional neural network with only facial images. Methods Based on the convolutional neural network VGG16 architecture, transfer learning is carried out on the facial images of 3738 subjects to classify TE and NTE, SE and NSE, and SY and NSY. Data augmentation techniques are used to increase classification performance. Results The classification performance of TE and NTE, SE and NSE, and SY and NSY was 77.24%, 85.17%, and 80.18% by F1 score and 80.02%, 85.96%, and 72.76% by Precision-Recall AUC (Area Under the receiver operating characteristic Curve) respectively. Conclusions It was found that Soeum person had the most heterogeneous facial features as it had the best classification performance compared to the rest of the constitution, followed by Taeeum person and Soyang person. The experimental results showed that there is a possibility to classify constitutions only with facial images. The performance is expected to increase with additional data such as BMI or personality questionnaire.

This paper statistically reviewed for the USNCAP frontal crash test results carried out by NHTSA. Vehicle samples were selected on total 20 vehicles which were included on 15 vehicles for MPV&SUV and 5 Pickup. The results was summarized as followings. The performance for the driver was better than the passenger's in the average sense. There exist distinctions between the driver and the passenger on the USNCAP front test procedure, for example dummy size, seating position and airbag style. Therefore these differences originated in the statistical results. Main effect was Neck injury for crash performance on both dummies on the average value. Root cause of neck injury was different for each dummy, ie, the driver caused from Nte & Ntf, but the passenger did absolutely Nte mode. Reliability evaluated from the standard deviation was highly dependent upon chest injury on the driver and neck injury on the passenger. Restraint system was also summarized.

With the contunuing trends towards an information based society, telecommunications services are becoming an integral part of social activities. So, emphasis on ISDN is growing rapidly and placed on supporting integrated services delivery of different levels to the end user. The end user’s perception of an integraged services delivery(in particular, ISDN services) should reflect three interrelated capabilities, ISDN access capabilities and ISDN network capabilities. For turning the ISDN concept of above capabilities into reality, we have implemented the experimental system on user-network interfaces, which are three kinds of implementations in user access arrangements, namely basic access, intermediate rate multiplexed access and primary rate multiplexed access. Through these implementations, NTE(Network Terminating Equipment) is used for single basic access [2B+D], IMUX (Intermediate rate Multiplexer) for 4 basic accesses [4X(2B+D)] and PMUX(Primary rate Multiplexer) for [10/12 X (2B+D)]. This paper describes the outlines of system features on user access equipments, system architectures of testbed and experiment result of each access arrangements.

wx 126조합으로부터 분리된 농녹색업과 담녹색엽 near-isogenic계통의 광합성 정도와 생장특성 및 수량관련형질들을 비교 검토한 결과를 요약하면 다음과 같다. 1. 농녹색엽계통이 담녹색영계통보다 엽록소 a, b 및 총엽록소 함량은 현저히 높았으나 엽록소 a, b의 비율은 큰 차이가 없었다. 2. 출수기 지엽에 있어서 단위엽면적당 광합성율은 농녹색엽계통이며 높았으나 단위엽녹소당 광합성량은 담녹색엽계통이 더 높았다. 3. 이앙부터 출수기까지의 CGR은 농녹색엽계통이 더 높았으며 이는 NAR이 높은 데서 기인된 것으로 해석되었다. 4. 농녹색엽게통의 주당수수, 주당영화수 및 주당수량은 담녹색엽계통에 비해 각각 높았으나 1,000입중과 등숙율은 두 계통간에 차이가 없었다.
