Vegetarians have claimed and actively promoted the advantages of plant-based alternative milks as the best option for human nutrition and health, compared to the natural dairy milk. However, numerous scientific evidences and reports have demonstrated that the natural milk possesses more beneficial nutrients and bioactive components than artificially manufactured plant-derived milks. The biochemical and nutritional advantages and functionalities of natural dairy milk cannot be replaced by man-made or crafted plant-based beverage products. On the other hand, the tremendous increase in production and consumption of the plant-based alternative milks in recent years has led a serious business downturn in traditional roles and stability of the dairy industry, especially in the major dairy producing Western countries. Although plant-based milk alternatives may have some benefits on nutrition and health of certain consumers, the plant-derived alternative milks may not overshadow the true values of natural milk. Milk is not a high fat and high cholesterol food as animal meat products. Unlike plant-based alternative milks, natural milk contains many bioactive as well as antiappetizing peptides, which can reduce body weight. It has proven that taking low-fat, cultured and lactase treated milk and dairy products with other diversified nutritionally balanced diets have been shown to be healthier dietary option than plant-based milk/foods alone.

주행 중 인체는 발과 지면 사이의 반복적인 충격력을 경험한다. 충격력은 하지의 부간 편안함 그리고 주행 능력과 높은 연관성이 있다. 이에 신발 메이커들은 하지의 부상을 줄이고 편안함을 향상시키며 주행 능력을 개선하기 위하여 다양한 특성의 중저를 가진 신발을 개발하여 왔다. 본 연구의 목적은 남녀 주행 시 수직 지면반력 및 착지각도에 미치는 신발 중저 경도의 영향을 조사하는 것이다. 이를 위하여 전문 주자 남녀 각각 다섯 명이 본 실험에 참여하여 연질 중질, 경질의 운동화를 순차적으로 신고 동일한속도로 주행하도록 하였다. 결론적으로 성별과는 무관하게 최대 수직 지면반력, 충격력 정점, 디딤 시간은 신발 중저의 경도의 영향을 주지 못하였다. 하지만 중저가 경질이 될수록 부하 시간은 감소하고 부하율은 증가하였다. 이때 남성 참여자가 중저의 변화에 대하여 큰 차이를 보이지 않은 반면 여성 참여자는 상대적으로 더 민감한 반응을 보였다. 저자들은 본 연구의 결과가 향후 성별에 특화된 신발의 적절한 중저 경도를 결정하기 위한 가이드라인을 제공하는데 적용되기를 기대하는 바이다.

This study aims to develop knee protectors that provide high safety and fitness, while incorporating a motion-adaptable 3D-printed pad. These protectors were evaluated by individuals who experience knee discomfort or pain. The results are as follows. First, the 3Dprinted pad design of a hexagonal mesh structure, which is modeled for excellent appearance and knee movement. Each unit of the mesh has a outer layer of 2mm thick, a spacer layer of 1 mm in diameter, and is connected by a 1.5 mm bridge. The bridge was extended up to 1.2 cm. Second, the knee brace was designed in three types - cylinder, strap, and combination by Universal design. Impact protection measurements of the three knee protectors demonstrated roughly 80% reduction in impact. Third, based on usability evaluation, cylinder type protectors have the highest ratings in most areas, primarily because of their ease of use. The strap type protector received positive reviews in terms of appearance and care, and the combination type provided stable knee protection. This study demonstrated the potential industrial application of 3D printing technology by designing and evaluating protective products for the human body. The results of this study are expected to aid knee protector manufacturers in developing practical products and promoting the development of protective equipment for other body parts or purposes.

Background; Pleural micro-metastasis of lung cancer is detected by touch print cytology or pleural lavage cytology, but its prognostic impact has not elucidated yet. We hypothesize that recurrence may depend on the amount of tumor cells disseminated in pleural cavity, if the invasiveness of all cancer is the same. To predict the amount of tumor cells disseminated in pleural cavity, we need pleural surface area, distributed pattern of cells and concentration of cells per unit area. Human pleural surface area has not reported yet. In this report, we calculate the normal human pleural surface area using CT image data processing. Methods; Twenty persons were checked CT scan, and we obtained the data from each image. In order to calculate the pleural surface, the outline of lung was firstly extruded from CT image data using home-made Digitizer program. And the distance between CT images was calculated from the extruded outline. Finally a normal human pleural surface was calculated from function between the distance of consecutive CT images and the calculated length. Results; Their mean age is $65{\pm}12$ years old (range $26{\sim}77$), body weight is $62{\pm}9\;kg\;(48{\sim}80)$, and height is $167{\pm}6\;cm\;(156{\sim}176)$. The number of images used is $36{\pm}7\;(24{\sim}51)$. Pleural surface area is $211,888{\pm}35,756\;mm^2\;(143,880{\sim}279,576)$. Right-side pleural surface area is $107,932\;mm^2$ and Lt is $103,955\;mm^2$. Costal, mediastinal and diaphragmatic surfaces of right-side pleura are $77,483\;mm^2,\;39,057\;mm^2,\;and\;8,608\;mm^2$ respectively, and left-side are $72,497\;mm^2,\;35,578\;mm^2,\;and\;4,120\;mm^2$ respectively. Conclusion; Normal human pleural surface area is calculated using CT image data at first and the result is about $0.212\;m^2$.

2020년 8월 4일에 베이루트항 저장 창고에 저장되었던 2750 ton의 질산암모늄이 폭발하였다. 이 폭발은 지금까지의 질산암모늄 폭발 중 가장 규모가 큰 것으로 알려졌다. TNT 등가법을 적용하여 2750 ton의 질산암모늄의 폭발 에너지에 상응하는 TNT 등가량을 구한 결과 856 ton으로 나타났다. Kingery-Bulmash 폭발 특성 계산기 툴을 활용하여 폭원으로부터 3600 m 까지의 범위에서 과압과 충격량을 산정하였다. 폭원으로부터 멀어짐에 따라 과압과 충격량은 지수적으로 감소하지만 과압이 더 크게 감소하여 과압이 충격량보다 거리에 따른 영향을 더 크게 받는 것으로 나타났다. 과압과 충격량이 구조물에 미치는 영향을 평가하기 위해서 구조물의 손상 기준을 적용한 결과 구조물의 부분적 붕괴, 심각한 손상, 가벼운 손상이 발생하는 임계거리는 폭원으로부터 각기 약 500, 800, 2200 m로 나타났다. 구조물과 인체의 손상 확률을 평가하기 위해서 프로빗 함수를 적용하였다. 구조물의 붕괴, 구조물의 심각한 손상, 구조물의 가벼운 손상, 창유리의 파손 가능성이 50% 이상이 되는 지점은 각기 약 500, 810, 2200, 3200 m가 되는 것으로 나타났다. 폭원으로부터 200 m 이내 지점에 있는 사람의 경우 폐 손상으로 인해 사망할 확률이 99% 이상인 것으로, 고막 파열이 발생할 확률이 50%인 지점은 약 300 m인 것으로 나타났다. 전신 이동에 따른 두개골 파열과 전신 충격에 의해 사망할 확률이 100%인 지점은 각기 300, 100 m인 것으로 평가되었다.

Purpose: The study aims to provide basic data to enhance the health of paramedics responsible for patient transport and treatment by analyzing the exposure level of paramedics to electromagnetic waves generated by electric devices used in ambulances. Methods: The study measured electromagnetic waves in ambulances in N region from July to December 2018. ME3030B produced by German Gigahertz Solutions was used to measure these waves and the maximum value was selected by moving it slowly in various directions. Each measurement part was selected and the mean value was calculated by repeatedly measuring at 10-minute intervals three times in total: $1^{st}$, $2^{nd}$, and $3^{rd}$ phase. Results: Among the electrical devices installed in the patient room of the ambulance measured at distances of 1 cm or 30 cm, results showed a high level of electric waves at the inverter ($26.25{\pm}39V/m$) and high level of electromagnetic waves ($564.00{\pm}31.75nT$) at the ozone sterilizer. According to measurements toward the front near the driver's seat, results indicated high levels of electric waves ($3.67{\pm}1.15V/m$) and electromagnetic waves ($450.00{\pm}19.52nT$) at the black box hard drive. Conclusion: Electromagnetic waves within the ambulance were stable and not beyond the range that might impact human health. However, in the case of the black box hard drive ($3.67{\pm}1.15V/m$, $450.00{\pm}19.52nT$) located under the passenger seat, it may have a direct effect on the human body and, thus it is necessary to move it to a storage area further away from the paramedics to minimized the impact.

Purpose: This study was conducted to develop a curriculum model for fundamentals of nursing at the graduate level which reflects a consensus of educators and the students in Korean nursing society. Method: A survey was used with three groups to identify consensus on a curriculum model for fundamentals of nursing at the graduate level; 42 educators in fundamentals of nursing, 11 nurse educators whose major was not fundamentals of nursing and 70 nurses with a bachelor degree in nursing. Results: Consensus on a curriculum model at the graduate level were delineated from analysis of the survey, Based on these results, a curriculum model fur fundamentals of nursing at the graduate level is outlined: As one major area of nursing, fundamentals of nursing focuses on nursing practice based on basic human needs. Thus main focus of the curriculum for fundamentals of nursing at the graduate level is research performance and theory development on nursing interventions to meet basic human needs in clinical settings. Conclusions: A curriculum model for fundamentals of nursing at the graduate level suggests that its application may have a positive impact on development of distinct knowledge body for fundamentals of nursing that will differentiate the content of education for undergraduate and graduate levels of nursing. However, the suggestion for the curriculum model needs to be refined and developed for application.
