The main purpose of the study is to figure out visitors' intentions for the Suanbo Spa Festival after they participated the events, programs offered from the Suanbo Festival organization. The visitors were also asked to evaluate contents, images, and convenience facilities of the festival. The study found that only visitors over 60s of age positively evaluate the festival, therefore, products such as traditional tea-making, herb-massage will attract old aged group. The findings suggests that event image and convenient facilities have impact on tourists' responses and intentions to their neighbors. The result of the study also recommend traditional participations such as horseback-riding, GaMa-riding, Korean traditional archery shooting to be added to the participating program.

Most construction disasters are analyzed to be human factors such as not complying with the safety regulations of construction sites, not using clothing and protective equipment, safety insensitivity, and the health of workers. In order to prevent such a construction disaster, the project site management needs to check the health of workers, but it is difficult to check the condition of workers every hour. Therefore, this paper proposed the design of digital safety-helmet that can automatically identify health conditions by checking workers $SpO_2$ and pulse rates, away from simple protective features.

인체동작 인식에 대한 연구는 재활치료, 운동선수의 동작 교정 및 모니터링, 3차원 애니메이션 제작등 많은 분야에서 필요로 하고 있다. 동작 인식에 대한 일반적인 방법으로는 반사 마커를 부착하여 여러 대의 적외선 카메라로 관절 운동을 관찰하는 방식이였다. 이러한 방식은 여러 개의 마커를 사용자들이 옷을 벗고 몸에 붙이거나 특수 복장을 착용해야 하는 불편함이 있을 뿐만 아니라 초기 위치 보정에도 많은 시간이 소모된다. 이와 같은 문제점을 해결하기 위하여 본 연구에서는 어떠한 특수 장비를 착용하거나 몸에 부착하지 않고 즉각적으로 인체의 움직임을 트래킹 할 수 있는 마커리스 트래킹시스템을 개발하였다. 이 시스템은 사람의 동작 분석을 하는데 있어 빠르게 측정 및 분석이 가능하고 특수 장비를 착용하지 않아도 됨으로 인해 동작에 방해를 받지 않아서 3차원 영상을 즉각적으로 확인할 수 있는 편리성을 갖추고 있다.

Animals must be inspected prior to and after slaughter to make certain they are free of diseases and unacceptable defects. Since meats are potentially hazardous foods, they should not be accept if there are any signs of contamination, temperature abuse, or spoilage. This survey was aimed to monitor the current situation of country-of-origin labels and sanitation for the meat markets in Seoul, Korea. The markets were divided into groups as to 25 territories in Seoul and the size of markets (large size, medium size, and small size). In terms of size distribution, small butcher shops occupied the highest percentage. On the itemized suitability test of unpacked and packed beer in Seoul, most butcher shops showed good evaluation. However, labels indicating the grade, storage and cooking instruction for unpacked beef were not properly posted on the products. The results of monitoring sanitation conditions for butcher shops in Seoul showed relatively low suitability. Especially, there were serious lack of knowledge about wearing the sanitation clothings, caps, and shoes. The problem with food safety is so complicated that producers, consumers, merchandisers, the press, the government and the scholar should try to solve the problems altogether. Also, it is important to educate and provide them with correct understanding and information for food hygiene and safety.

This study was conducted to examine the effects of the elderly patient's simulation experience on attitudes toward elderly and elderly patients, and empathy of elderly patients among nursing students. Study results showed that elderly patient's simulation experience did not have significant effects on attitudes toward elderly or elderly patients, whereas it had significant effect on enhancing the empathy on elderly patients. The subjects of experimental group indicated that the factors decreasing the effect of intervention are single event of experience, raising aging anxiety, lack of the reality of simulation clothing, and risk of accident during simulation experience, etc. In order to maximize the positive effects of the elderly patient's simulation program, it is necessary to find a way to improve those limiting factors identified from this study, and to continue to work on positive effects of elderly simulation applied for their curriculum.

In large ships with complex structures, it is difficult to locate workers. In particular, it is not easy to detect when a worker falls down, making it difficult to respond quickly. Thus, research is being conducted to detect fallen workers using a camera or by attaching a device to the body. Existing image-based fall detection systems have been designed to detect a person's body parts; hence, it is difficult to detect them in various ships and postures. In this study, the entire fall area was extracted and deep learning was used to detect the fallen shipworker based on the image. The data necessary for learning were obtained by recording falling states at the shipyard. The amount of learning data was augmented by flipping, resizing, and rotating the image. Performance evaluation was conducted with precision, reproducibility, accuracy, and a low error rate. The larger the amount of data, the better the precision. In the future, reinforcing various data is expected to improve the effectiveness of camera-based fall detection models, and thus improve safety.

The seated stone Buddha(Bon5190) of National Museum of Korea initially consisted of some 90 fragments, making it difficult to guess its overall appearance. Under a restoration work which lasted four months, the fragments were joined together, giving shape to a seated Stone Buddha in Bhumisparsa(earth touching) mudra and an associated figure of Bodhisattva missing the face. The statue was made from a single stone block by digging out the center. Traces of lacquer coating and a gilded layer above the lacquer coat were found in various parts. Polarizing microscopy and XRD analysis revealed that the stone was zeolite, a mineral formed through diagenesis of volcanic glassy ashes from trachytic tuff (Nuldaeri) and dacitic tuff (Guryongpo). In Korea, zeolite deposit found mostly in Gyeongsangbuk-do, in places like Yeonil, Guryongpo, Gampo and Ulsan. The restored statue of seated Buddha proved very similar in appearance to the seated stone Buddha of Deoksa Temple in Cheongdo-gun, Gyeongsangbuk-do (housed in Yeongsanjeon Hall). The scroll inside the statue, containing information about the background and circumstances of creation of this Buddhist sculpture, indicates that the monk Seung-ho took part in it as the head sculptor-monk.

The purpose of this paper is to implement a deep learning-based real-time video analysis algorithm that monitors safety of workers in industrial facilities. The worker's clothes were divided into six classes according to whether workers are wearing a helmet, safety vest, and safety belt, and a total of 5,307 images were used as learning data. The experiment was performed by comparing the mAP when weight was applied according to the number of learning iterations for 645 images, using YOLO v4. It was confirmed that the mAP was the highest with 60.13% when the number of learning iterations was 6,000, and the AP with the most test sets was the highest. In the future, we plan to improve accuracy and speed by optimizing datasets and object detection model.
