The role of QR Code robots in smart logistics is great. Cognitive robots, such as logistics robots, were mostly used to adjust routes and search for peripheral sensors, cameras, and recognition signs attached to walls. However, recently, the ease of making QR Codes and the convenience of producing and attaching a lot of information within QR Codes have been raised, and many of these reasons have made QR Codes recognizable as visions and others. In addition, there have been cases in developed countries and Korea that control several of these robots at the same time and operate logistics factories smartly. This representative case is the KIVA robot in Amazon. KIVA robots are only operated inside Amazon, but information about them is not exposed to the outside world, so a variety of similar robots are developed and operated in several places around the world. They are applied in various fields such as education, medical, silver, military, parking, construction, marine, and agriculture, creating a variety of application robots. In this work, we are developing a robot that can recognize its current position, move and control in the directed direction through two-dimensional QR Codes with the same horizontal and vertical sides, and the error is to create a QR Code robot with accuracy to reach within 3mm. This paper focuses a study on the speculative navigation using auxiliary encoder during the development of QR Code-aware indoor mobility robots.

The aim of this study was to introduce the foods recorded in「Bongjeopyoram」, a cookbook, of which the date of production and author are unknown. This was described in an old document belonging to the Hansan Lee family clan from Chungcheongnam-do and revealed its content and significance in the food culture history of Korea to academia for the first time, A close examination of「Bongjeopyoram」 showed that, as with other cookbooks from the Joseon Dynasty, it started with methods of making alcoholic beverages. This was followed by recipes for different types of food in the following order: rice cakes and confectioneries, jeol-sik (seasonal foods), daily meals, foods made for jesa (ancestral rites) or a feast, food for weddings, and food for sijeol-jesa (seasonal ancestral rites). The book contained a total of 18 types of alcoholic beverages, 11 types of rice cakes and confectioneries, 20 types of daily meals, 28 types of jeol-sik and food for sijeol-jesa, 12 types of food for jesa and feasts, and 37 types of food for weddings, for a total of 126 types of food and beverages.「Bongjeopyoram」 was an ancient cookbook with detailed records on how to carry out jesa, which was an important event hosted by jonggas, or the head family of a family clan, and how to receive and serve guests in the Joseon period. This book is expected to play a valuable role as a guidance with significance as a cookbook of a jongga from the Joseon Dynasty, a time when bongjesajeopbingaek (hosting jesa for one’s ancestors and serving one’s guest) was considered important.

추측항법과 Loran C 항법을 결합한 Hybrid 항법의 정도를 평가하기 위하여, 군산수산전문대학 실습선 전북 401, 403 호에 설치되어 있는 Hybrid항법장치를 이용하여 1982년 7월부터 1983년 6월 사이에 한국서해안 해역에서 실선관측을 행하여 그 측위의 정도를 Radar 위치와 비교.검토한 결과는 다음과 같다. 1. 9970, 5970 Chain의 Loran C 시간차의 표준편차는 각각 약 0.21μs, 약 0.06μs로 5970 Chain의 시간차 변동이 9970 Chain보다 적었다. 2. Hybrid위치와 Loran C 위치는 Radar 위치와의 편위거리가 각각 약 0.4 mile, 약 0.51 mile로서 Hybrid 항법이 Loran C 항법보다 정도가 더 높았다. 3. Hybrid 위치와 Loran C의 계산기 simulation 위치는 Radar 위치와의 위치거리가 각각 0.4 mille, dir 0.98 mile로 Hybrid 항법이 Loran C의 계산기 simulation 위치보다 정도가 더 높았으며, 추측위치의 미소한 변동에 대한 Loran C의 변위량을 보정하면 Loran C의 계산기 simulation 위치의 정도도 더 높일 수 있음을 알 수 있었다.

A chi-square test was performed in terms of MBTI personality types and horticultural preferences, where the MBTI personality types were obtained from the predicted results from the typical expressions of the Korean Psychological Testing Institute’s self-speculation MBTI preference indicator. The analysis results were organized into two types: intuition type and sensing type. The results suggest that the intuition type preferred the herbs with fragrances, while the sensing type showed their preference towards flowering plants. Also, there were significant differences between the intuitive and sensing types with respect to ‘five senses that are the most stimulating in the horticultural process’, ‘plant characteristics’ and ‘interesting horticultural activities’, which imply that different types have different choices. In the comparison between thinking type and feeling type, the thinking type showed their interest in the overall shape of the plant, while the feeling type showed their first interest in the flowers of the plants. The result showed that thinking type and feeling type had a significant difference in terms of ‘degree of preferences in horticultural activities’, ‘initially interested plant tissues’, ‘five senses that are the most stimulating in the horticultural process’ and ‘effects of horticultural activities’. Regarding the judging type and perceiving type in their choices of plant characteristics, the judging type preferred flower plants, while perceiving type preferred herbs with fragrances. The results of self-speculation MBTI personality test showed significant differences according to the personality types, regarding the most interested plant tissue and plant characteristics, which leads to a difference in their choices.

확산 텐서 영상을 이용하여 뇌경색 환자의 손상된 백질 섬유를 시각화할 수 있게 되었다. 본 연구의 목적은 뇌경색 환자에서 NIHSS와 분할 비등방도의 상관을 평가하고자 하였다. MR 확산영상에서 뇌경색이 확인된 16명(남:11, 여:5, 평균연령 61세) 환자를 대상으로 24방향 DTI를 시행하였다. 뇌경색 발발 후 2주 이내에 증상이 개선된 환자 9명과 증 세가 악화된 환자 7명으로 구분하였다. FA값의 정량측정을 위해 병소와 병소 반대측이 통계적으로 유의한 차이가 있 음을 확인하였다. 확산강조영상에서는 병소가 고신호로 보였으나, FA값은 정상측 보다 낮게 측정되었다. NIHSS상의 임상증상이 개선된 환자들의 FA값은 0.41, 반대측 정상부는 0.49로 병소측이 15%정도 낮게 측정되었다. 그러나 NIHSS상 증상이 악화된 환자들의 경우 병소측 FA값이 0.28, 반대측 정상부는 0.56으로 큰 차이를 보였다. 결론적으 로 DTI에서의 FA값은 뇌경색 환자의 예후를 평가하는데 매우 유용한 지표로 이용될 수 있을 것이다.
