The objective of this study was to develop remedies to improve sanitary quality of school meals. To analyze the usage of potentially hazardous foods, menus from 180 school foodservice establishments were collected through school websites. Statistical analyses were conducted using the SPSS package program (ver. 20.0). The results of this study are as follows: analysis of the foodservice production process revealed that the following were employed: heating process (70.5%), non-heating process (16.3%), and after-heating process (13.2%). In addition, the cooking methods used for side dishes were: stir-frying (22.1%), saengchae (21.3%), sukchae (15.2%), jorim (12.4%), deep-frying (10.2%), and grilling (9.5%). Overall, 64 menu items known to pose potential microbiological hazards were offered a total of 2,671 times. The usage frequency was high for bibimbap, pork-bulgogi, cucumber-saenchae, seasoned bean sprouts namul, seasoned spinach-namul, and korean cabbage-geotjeori. In conclusion, in order to increase the sanitary quality of school meals, menus or foods that contain microbiological hazards should prepared very carefully with respect to time and temperature management during food production. Also, school foodservice employees must possess proper food safety knowledge and techniques for applying the HACCP system to prevent foodborne illness.

의인화의 영향력에 대한 연구들은 점차 늘어나는 추세이나, 의인화를 경험하는 이용자의 특성 및 이들의 이용행태에 관해서는 탐색이 부족한 편이다. 따라서 본 연구에서는 구체적으로 스마트 스피커 이용자의 의인화 수준에 따른 이용자의 외로움, 사회적 단절, 애착 및 스피커 이용행태의 차이에 관해 탐색해보고자 하였다. 스마트스피커 이용자들을 대상으로 온라인 설문조사를 진행하였고, 총 320명의 이용자들이 조사에 참여하였다. 의인화 수준에 따라 두 집단으로 나누어 집단 간 차이를 살펴본 결과, 이용자의 외로움, 사회적 단절, 애착불안, 하루 평균 스피커 이용 빈도 및 의인화 행동 수준에 통계적으로 유의미한 차이가 나타났고, 애착회피는 통계적으로 유의미한 차이를 나타나지 않았다. 연구결과를 통해, 스피커와 긍정적인 사회적 상호작용을 높일 수 있는 인터랙션 설계에 관한 주요한 시사점을 제공할 수 있을 것으로 기대한다.

현행 5G 특화망 이용절차는 신청, 심사, 이용, 이용 점검의 단계를 거치며 주파수 할당 전 절차로 신청, 심사단계, 주파수 할당 후 절차로 이용, 이용점검 단계로 구분할 수 있다. 5G 특화망 신청을 위해서는 여러 종류의 서류 제출이 필요하며, 서류 심사 과정과 5G 특화망 주파수 이용을 위한 무선국 검사로 인해 5G 특화망 신청 사업자가 실질적으로 특화망을 사용하기까지의 절차가 복잡하고, 상당한 시간이 소요된다. 본 논문에서는 현행 프로세스보다 신속하고, 간소화된 5G 특화망 주파수 할당을 위해 블록체인 플랫폼을 사용한 5G 특화망 주파수 할당 프로세스를 제안하였다. 블록체인 플랫폼과 NFT(Non-Fungible Token) 활용을 통해 주파수 할당 과정에서 필요한 데이터의 신뢰성과 무결성을 확보하였고, 주파수 이용 정보의 보안 유지와 신뢰 가능한 5G 특화망 주파수 할당 프로세스를 구축하였다. 또한 사람의 개입을 최소화하는 RPA 시스템을 적용하여 5G 특화망 할당 과정에서의 공정성을 확보하였다. 마지막으로 모의실험을 통하여 이더리움 블록체인 기반의 5G 특화망 주파수 할당 프로세스를 수행하였다.

Background and objective: The purpose of this study was to comprehensively analyze the user behavior in order to cope appropriately with the increasing demand for mountain usage of those in their 20s and 30s and to allocate resources efficiently. Methods: To analyze the behavior of mountain hiking users, an exploratory data analysis (EDA) was conducted on the data which had been collected in the app Tranggle. The main target are users in their 20s and 30s who visited the mountains in the metropolitan area in 2019-2020. Among them, we have selected data on the top 13 mountains based on the frequency of visits. After data pre-processing, mountain usage patterns were analyzed through statistical analysis and visualization. Results: Compared to 2019, the number of users in 2020 increased 1.36 times. The utilization rate of the well-established hiking trails has also increased. The usage of mountain on weekends (Saturday > Sunday) was still the highest, and the difference in the usage between the days of the week decreased. Outside of work hours, early morning usage has increased and night-time usage has decreased. There was no significant change in usages depending on activity type, level (experience point) and exercise properties. Conclusion: Since the COVID-19 outbreak, the usage of mountains has been changing towards low user density and short-distance trip. in the post-COVID-19 era, the function and role of forests in daily life are expected to increase. To cope with this, further research needs to be carried out with consideration of the wider demographic and social characteristics.

To suggest a standard concerning with the arrangement of bridge equipment, the authors conducted the video observations with 3CCD (charge coupled device) cameras installed on the ceil of the bridge for monitoring the working activities of two bridge teams (the skipper/mate1 and the skipper/mate2) in a Korean coastal large trawler(gross tonnage: 139) for five days from July 30th. 2010 and analyzed of the data. Work elements coded by the work activities were input on the sheet of work analysis by the time unit of 1 sec according to the time occurred. A single work element among the work activities for every 5 minutes was denoted as the number of occurrence. The frequency of equipment usage was limited only in the usage of the equipment. In the case of the navigation and the towing net two ranks were integrated and analyzed. On the other hand, in the case of the casting net and the hauling net, two processes were integrated to as one and then analyzed separately as two ranks. As the results, 15 elements of work was carried out between two bridge teams for the observation; lookout, radar, GPS plotter, fish finder, net monitor, fishing deck, RPM indicator, rudder angle indicator, compass card, for maneuver; steering, ship speed control, trawl winch operation and external communications, paper works and others. It was found that the work load of the skipper per 5 minutes accordance with the navigation, the casting net, the towing net and the hauling net are 20.5 times, 11.9 times, 38.0 times and 9.5 times respectively, the mates are 65.2 times, 66.5 times, 85.7 times and 59.1 times respectively. The radar was shown the highest frequency of the equipment usage and the next was the fish finder, the GPS plotter and the external communications in the case of the navigation. In the case of the towing net the frequency of usage was high the ranking as the radar, the net monitor, the fish finder, the GPS plotter, the steering system and the external communications. In the case of the integrated process both of the casting and hauling net the trawl winch was shown the highest frequency to the skipper and the next was the GPS plotter and the radar, and the steering system was shown the highest frequency to the mate and the next was the radar, the ship speed control system, the GPS plotter, the net monitor and the fish finder.

Conventional research on customer relationship management(CRM) in general has focused on the effects of individual customer's satisfaction, retention and profit management. However, corporate customers are more profitable than individual customers because of high volume and frequent transactions between companies. In this article, a prototype for a corporate customer relationship management is developed in the postal service. First, the frequency and amount of customers' usage were examined, and thereby the corporate customer rating scheme was established to provide customized service. Second, five different types of usage patterns were determined using clustering analysis. In addition, we presented the rationales behind the five types of patterns. Third, RFM(recency, frequency, monetary) analysis was performed, and then action plans were developed to increase sales. Finally, the prototype software was developed to automatically perform the above analysis using MS Excel program.

People have studied English using online English dictionaries when they looked for the meaning of English words or the example sentences. These days, as the AI technologies such as machine learning have been developing, documents can be translated in real time with Kakao, Papago, Google translators and so on. But, there has still been some problems with the accuracy of translation. The AI secretaries can be used for real-time interpreting, so this kind of systems are being used to translate such the web pages, papers into Korean. In this paper, we researched on the usage frequency of the combined English phrases from dictionaries by analyzing the number of the searched results on Google. With the result of this paper, we expect to help the people to use more English fluently.
