The Influence of Different Exercise Modes on College Students’ Cardiopulmonary Fitness
Wu, Dezhi(띠즈우),Han, Hanjun(한준한),Sun, Jingquan(선징콴) 한국웰니스학회 2019 한국웰니스학회지 Vol.14 No.3
이 연구는 8주간의 고강도 간헐적 훈련(HIIT)과 중강도 연속 훈련(MICT)과 태극권 운동(TCFR)이 심혈관 건강에 미치는 영향을 조사했다. 60명의 피실험자가 연구에 참여하였고, 세 그룹의 45명은 주당 3회, 회당 50분씩, 총 8주 동안 총 24번의 운동프로그램을 완료했다. 대조그룹(CON)은 운동프로그램에 참여하지 않았다. 최대산소섭취량(VO2max) 측정 후, 키, 체중, 안정시 심박수(HR)가 측정되었고, 개별적 운동 프로그램이 설정되었다. 각 운동 그룹은 연구 목적에 필요한 운동프로그램에 참여하였다. 훈련 2, 4, 6, 8주에 VO2max와 심박수를 측정하였다. 3개의 다른 운동 훈련 방법은 VO2max (HIIT+6.92%, MICT+10%, TCFR+10.4%)의 증가, 안정시 HR (HIIT-6%, MICT-3% 운동-5.4%)의 감소, 운동부하검사 중 첫 번째 부하 직후 HR(HIIT+18.7%, MICT+8%, TCFR+11.89%)의 증가, 운동부하검사 중 두번째 부하 직후(HIIT+17.51%, MICT+7.24% TCFR+9.37%)의 증가를 보였다. TCFR은 VO2max를 증가시키고, 심박수를 줄이며, 심폐 기능을 향상시켰다. HIIT는 MICT와 TCFR보다 VO2max를 향상시키고, 안정시 심박수를 줄이며, 심폐 기능을 향상시켰다. To observe the effects of 8week high intensity intermittent training(HIIT), moderate intensity continuous training(MICT), and Tai Chi fitness running(TCFR) on cardiopulmonary fitness. We recruited 60 subjects in this study. 45 in the intervention group completed 24 intervention training sessions(3 times a week, 50 min each time) over 8 weeks. and 15 in the control group(CON), did not perform the exercise. After the baselinemaximal oxygen uptake(VO2max), height, weight, and resting heart rate(HR) Values were determined, the HIIT, MICT, and TCFR groups performed the HIIT, MICT, and TCFR groups performed the HITT, MICT, and TCFR exercise programs respectively VO2max and HR were measured at the 2<SUP>nd</SUP>, 4<SUP>th</SUP>, 6<SUP>th</SUP>, and 8<SUP>th</SUP> training weeks The three different training methods have obvious effects on improving VO2max(HIIT+6.92%, MICT+10%, TCFR+10.4%), reducing the resting HR(HIIT-6%, MICT-3%, TCFR-5.4%), increasing the heart rate immediately after the first load (HIIT+18.7%, MICT+8%, TCFR+11.89%) as well as increasing the heart rate immediately after the second load(HIIT+17.51%, MICT+7.24%, TCFR+9.37%). The three different training methods markedly improved VO2max(HIIT-6.92%, MICT+10%, TCFR-10.4%), decreased resting HR(HIIT-6%, MICT-3%, TCFR-5.4%), increased HR immediately after the first load(HIIT-18.7%, MICT-8%, TCFR-11.89%) and increased HR immediately after the second load(HIIT+17.51%, MICT+7.24%, TCFR+9.37%). TCFR is more effective than traditional MICT at increasing VO2max, decreasing resting HR, and improving cardiopulmonary fitness. HIIT has tremendous ability to increase VO2max, decrease resting HR, and improve cardiopulmonary fitness. HIIT has tremendous ability to invrease VO2max, resting HR, and cardiopulmonary fitness.

Scalable Multiple NameNodes Hadoop Cloud Storage System
Kun Bi,Dezhi Han 보안공학연구지원센터 2015 International Journal of Database Theory and Appli Vol.8 No.1
To solve the problem that the total number of files in HDFS is limited by the memory size of the NameNode, the paper proposed a scalable multiple NameNodes coexisting scheme for cloud storage. NameNode location service (NLS) was introduced into the system. NLS communicated with all NameNodes and was responsible for the file location requests from the clients. Experimental results showed this scheme had good scale-out scalability and the upper limit of the total number of files that the system was able to store could be greatly increased by adding a number of NameNodes.

Recent progress on the traditional and emerging catalysts for propane dehydrogenation
Fushan Feng,Haiyuan Zhang,Shaoqi Chu,Qinqin Zhang,Chao Wang,Guang-Jian Wang,Fang Wang,Liancheng Bing,Dezhi Han 한국공업화학회 2023 Journal of Industrial and Engineering Chemistry Vol.118 No.-
Propene is an important chemical raw material with continuously growing demand from the propenedownstream industry. Compared with the traditional catalytic cracking process and steam cracking ofnaphtha, the propane dehydrogenation (PDH) process is an attractive alternative to efficiently producehigh-purity propene. Presently, the traditional Pt-based and Cr-based catalysts for PDH are mainly usedin commercial processes. And the non-noble metal catalysts and carbon catalysts for PDH also receiveincreasing attention with the development of research both from academia and industry. In this review,the recent progress on the traditional catalysts, the emerging non-noble metal catalysts, and carbon catalystswas summarized, together with the discussion of the key research issues and development directionof these PDH catalysts. This review could provide the theoretical and technical foundation fordeveloping novel high-efficiency PDH catalysts.
