This paper aims to identify the characteristics and the current situation of the architectural characteristics, children's characters using facilities, and status of management and utilization by surveying 'Day Service for Children' in Tokyo-do. First, About the status of management and utilization, 'Day Service for Children' is operated by a local government, NPO corporate group and social welfare corporate. There are not big differences of the care program or running hours depending on operating principals but there are differences depending on staff organization, number of children and space constitution. Also, infants ratio at 'Day Service for Children' is high for the purpose of detecting disability early and supporting their development early. They have diverse disabilities but developmental disabilities' ratios high and most children are using both this facility and normal nursery centers together. Samples for proper child care based on status of space constitutions were installing lock, raising door knobs and using softer floor materials which are for children's safety. For the problem of space utilization, most comments were about lack of space which is not enough for teaching and training materials. Therefore, as an example, observation rooms for parents and teachers were sometimes used as storages and it changes teachers' moving direction, staying area and behavior zone. The programs of 'Day Service for Children' are divided to group teaching and private one. It will be the best if they have separate spaces such as group class room, private class room and play room. When they were operated by NPO corporate group or Social welfare corporate, there are many cases that their space was not properly zoned for each activity.

Purpose The purpose of this study is to analyze the impact of policy changes in Busan's local currency, Dong Baek Jeon, on the use of Dong Baek Jeon. In particular, this study tried to investigate consumption changes due to changes in local currency policy depending on the region, industry, and consumer characteristics. Design/methodology/approach This study used the transaction data of Dong Baek Jeon franchise for analysis. Specifically, the data from January 2022 to December 2022 were used to analyze the current status of the use of Dong Baek Jeon and changes in consumption before and after policy changes. Findings As a result of the analysis, the consumption of Dong Baek Jeon tended to be concentrated in specific regions, industries, and ages. In most regions and ages, the top consumption industries were similar. The use of Dong Baek Jeon showed a clear change in the pattern of use depending on policy changes. Specifically, when the benefits were revised downward, the use of Dong Baek Jeon decreased, and when it was revised upward, it increased. Depending on the policy change, the rate of increase and decrease by region and consumer characteristics was relatively similar, but it was confirmed that there was a difference in the rate of increase and decrease depending on the industry.

This study was conducted to analyze the microbiological contamination status of raw beef distributed in Korea, and evaluate the suitability of current aerobic plate count (APC) guidelines. We analyzed five years (2010-2014) of microbiological monitoring data obtained from the Ministry of Food and Drug Safety and investigated the microbiological status of raw beef collected from meat packing centers and meat shops in the Seoul/Gyeonggi, Gangwon, and Chungcheong regions in August 2015. From 2010-2014, most raw beef (>94%) displayed APC levels of < $1.0{\times}10^6CFU/g$. However, raw beef samples collected from all three regions in August 2015 had comparatively higher APC levels than those reported in previous years. To evaluate the relationship between the APC level and quality, changes in beef loin were evaluated during cold storage for 15 days at $4^{\circ}C$. On day 11, the mean APC level ($4.7{\times}10^6CFU/g$) conformed to current guidelines in Korea ($1.0{\times}10^7CFU/g$) and the pH value was 5.82. However, the sensory evaluation score for color and overall acceptability was under 3.0, meaning that the beef loin was not acceptable for eating. These results suggest that current APC guideline for raw beef should be lowered to $1.0{\times}10^6CFU/g$ to improve both the microbiological safety and palatability of raw beef.

The second harmonic component could be decreased by magnetizing inrush when there have been changes to the material of the iron core or its design methodology. The higher the capacitance of the high voltage status and underground distribution, the more the differential current includes the second harmonic during the occurrence of an internal fault. Therefore, the conventional second harmonic-restrained RDR needs modification. This paper describes an advanced numerical algorithm that utilizes terminal voltage, differential current harmonics, harmonic ratio, and flux-differential current slope. Based on the results of testing with WatATP99 simulation data, the proposed algorithm was proven to be faster and more reliable.

Purpose - This study investigated the development process of the Chinese distribution industry and analyzed the current status of China's offline and online distribution industries under the development process of the Chinese distribution industry. In addition, the current status of offline distributors in China and representative companies were analyzed as case studies. Research design, data, and methodology - This study analyzed the overall environment of the Chinese distribution industry by using literature data. Then, this study conducted a case analysis using RT Mart and Jingdong, major companies in the distribution industry. Result -The main research results of this study show that the Chinese distribution market has already matured, and retailers are fiercely competing to secure sales and operating profits through various methods such as finding new management methods, improving awareness and customer loyalty by expanding the number of stores. Conclusion -Recently, the characteristic of China's distribution industry is that the boundaries of distribution are breaking down. Chinese retailers are taking strategies to expand the scope of services by erasing the boundaries of distribution. In other words, distribution companies are promoting a borderless distribution strategy in which consumers purchase products online and offline without restrictions on time and space. In addition, small stores in residential areas are on the rise compared to large-scale stores in the city center. The existing distribution industry operates various types of distribution stores to prepare for the post-COVID-19 crisis.

현재까지 HR-WPAN(High Rate-Wireless Personal Area Network)에 제안된 LDS(Link-status Dependent Scheduling) 알고리즘(algorithm)은 전체 네트워크(network)의 처리율(throughput) 향상만을 목적으로 함으로서, worst-link에 상대적으로 중요한 디바이스(device)가 연결된 경우, 그 디바이스의 처리율은 더욱 악화 된다. 본 논문에서 제안한 WGS(Worst-case Guaranteed Scheduling) 알고리즘은 link 상태가 변하더라도 모든 디바이스의 처리율을 동일하게 유지함으로써, worst-link에 연결된 디바이스의 처리율을 어느 정도 보장하고 전체 네트워크의 지연은 기존의 LDS 알고리즘보다 감소시킬 수 있다. 따라서 향후 HR-WPAN의 설계 시 worst-link에 연결된 디바이스의 처리율을 어느 정도 보장하고 전체 네트워크의 지연을 감소시키고 싶을 경우, 본 논문에서 제안한 WGS 알고리즘이 유용하게 사용될 수 있을 것이다.

Varicella is a highly infectious disease caused by the varicella zoster virus. The varicella vaccine was developed by Michiaki Takahashi in Japan in 1974. Despite the worldwide distribution of efficient vaccines, varicella vaccination policy is extremely variable from country to country. Although varicella vaccine is not currently recommended for universal vaccination in Japan, most countries throughout Europe, and developing countries, it had been introduced into Korea in 1988 and 20 years have elapsed since its use. Currently, varicella vaccine has been most extensively used in the United States where routine 2-dose vaccination program has been recently implemented for children. Recent 2-dose schedule in the United States and the availability of combination measles-rubella-varicella vaccines may lead to future varicella vaccination policy changes in many countries. With this background, this article summarizes the current status of varicella vaccination policies worldwide and presents provisional updated recommendation of varicella vaccination in Korea.
