안성훈,정재우,오세종 (사)디지털산업정보학회 2022 디지털산업정보학회논문지 Vol.18 No.1
This study analyzes the success factors of OTT original content through big data, and intends to suggest scenarios, casting, fun, and moving elements when producing the next work. In addition, I would like to offer suggestions for the success of ‘Squid Game Season 2’. The success factor of 'Squid Game' through big data is first, it is a simple psychological experimental game. Second, it is a retro strategy. Third, modern visual beauty and color. Fourth, it is simple aesthetics. Fifth, it is the platform of OTT Netflix. Sixth, Netflix's video recommendation algorithm. Seventh, it induced Binge-Watch. Lastly, it can be said that the consensus was high as it was related to the time to think about ‘death’ and ‘money’ in a pandemic situation. The suggestions for ‘Squid Game Season 2’ are as follows. First, it is a fusion of famous traditional games of each country. Second, it is an AI-based planned MD product production and sales strategy. Third, it is casting based on artificial intelligence big data. Fourth, secondary copyright and copyright sales strategy. The limitations of this study were analyzed only through external data. Data inside the Netflix platform was not utilized. In this study, if AI big data is used not only in the OTT field but also in entertainment and film companies, it will be possible to discover better business models and generate stable profits.

Purpose: To assess the potential of dual-energy computed tomography (DECT) to identify urinary stone components, particularly uric acid and calcium oxalate monohydrate, which are unsuitable for extracorporeal shock wave lithotripsy (ESWL). Materials and Methods: This clinical study included 246 patients who underwent removal of urinary stones and an analysis of stone components between November 2009 and August 2013. All patients received preoperative DECT using two energy values (80 kVp and 140 kVp). Hounsfield units (HU) were measured and matched to the stone component. Results: Significant differences in HU values were observed between uric acid and nonuric acid stones at the 80 and 140 kVp energy values (p<0.001). All uric acid stones were red on color-coded DECT images, whereas 96.3% of the nonuric acid stones were blue. Patients with calcium oxalate stones were divided into two groups according to the amount of monohydrate (calcium oxalate monohydrate group: monohydrate≥90%, calcium oxalate dihydrate group: monohydrate<90%). Significant differences in HU values were detected between the two groups at both energy values (p<0.001). Conclusions: DECT improved the characterization of urinary stone components and was a useful method for identifying uric acid and calcium oxalate monohydrate stones, which are unsuitable for ESWL.
배경변인에 따른 학생의 SW교육에 대한 인식 차이 분석
안성훈 한국컴퓨터교육학회 2017 컴퓨터교육학회 논문지 Vol.20 No.6
본 논문에서는 2016년도에 68개 SW교육 연구학교 학생들을 대상으로 조사된 SW교육에 대한 인식을 학교급, SW교육 기간, 인터넷 사용 시간 등의 배경요인별로 차이를 살펴보고 학생들의 SW교육에 대한 인식과 배경요인 간에 어떤 관련이 있는지를 분석하였다. 그 결과, 학교급이 낮을수록, SW교육 기간이 길수록, 가정에서의 인터넷 사용 시간이 1시간~2시간 정도로 적당할수록 SW교육에 대한 인식이 긍정적인 것으로 판단되었다. 그러나 SW교육 기간과 인터넷 사용 시간이 학생들의 SW교육에 대한 인식에 유의미한 영향을 미치지는 않는 것으로 판단되었다. 이와 같은 분석 결과에 따라 중학교에서 학생들의 흥미를 유발할 수 있는 교수학습 방법, 장기간의 SW교육에서 학생들의 흥미를 유지할 수 있는 효과적인 교수학습 방안, 가정에서 적당하게 인터넷을 사용할 수 있도록 학생들을 지도하고 학부모를 계도하는 방안 등의 필요성을 제안하였다. In this paper, I analyzed on the differnce of thinking for SW education of SW education research schools' students in 2016 according to background variables – school level, period of SW education and time of internet using. Also, I analyzed the corelation between student’s thinking for SW education and background variables. As a result, I found the lower school level and the longer period of SW education, the more positive thinking for SW education is. Also, I found that when time of student's internet using are 1 hour or 2 hour, student's thinking for SW education is the most positive. But I confirmed that the period of SW education and time of student’s internet using didn’t give any influence to student’s think for SW education. Based on result of analysis, I proposed necessities for research of method that method middle school student feel interesting on SW education and method that student keep interesting on long-term SW education.

Biocatalysts, referred as enzymes, have been widelyused in life, industrial, medical, and biological fields due totheir high catalytic activity and substrate specificity for specificreaction. However, it has disadvantages in industrialapplications due to the drawbacks in its characteristics as a catalyst,such as the high cost, the narrow operation conditions interms of pH and temperature, and the low durability. Recently,many studies on nanozymes for replacing enzymes have beenwidely conducted to overcome these drawbacks. The nanozymehas a relatively wide pH and temperature operation rangeas compared with the enzyme, which is a kind of protein, andhas a high durability over a long period of time. It is also expectedto be able to be mass-produced at relatively low cost. However,the nanozymes still lacks of the substrate specificity, whichis one of the most important features of enzymes. Furthermore,only few nanozymes have been reported which exhibitshigher or comparable catalytic activity compared with enzymes. This review first discusses the classification of the nanozymesand the corresponding catalytic reactions, focusing on the mostdeveloped peroxidase -mimicking nanozymes. Then, it summarizesthe most effective peroxidase nanozymes including iron oxides,nanocarbon, and iron- and carbon composite materials and theircorresponding reaction mechanisms. After that, the nanotechnologybasedapproaches to improve the catalytic activity of nanozymesas well as the substrate specificity are covered. Furthermore,the current major application of nanozyme to the biosensor areintroduced. Finally, the future directions for nanozyme researchesand the applications are suggested

Objectives : This study was produced to examine the effects of moxibustion that had been played important role to traditional oriental medical treatment on disease. Recently, it was reported that moxi-tar which is generated in the process of moxibustion as burning combustibles decreased NO and iNOS generation in C6-glioma and RAW 264.7 cells in our lab. Methods : C6-glioma cells were cultured in RPMI 1640 with FBS 10% in CO2 incubator. To study the protective effects of moxi-tar, we observed cell viability, DPPH activity, SOD activity, catalase activity and cell morphology after injury with H2O2. Results and Conclusions : Moxi-tar increased cell viability about twice as much as that of being injury by H2O2 (moxi-tar 40 ㎍/㎖, H2O2 500 μM). And the results of free radical scavenger activity(80 ㎍/㎖ : 78.91 ± 4.4%), SOD activity and catalase activity(80 ㎍/㎖ : 21.6 unit/mg protein) were increased by moxi- tar as dose-dependent manner. So we concluded that the effects of moxibustion which is played important role in Oriental medicine, might be free radical scavenger effects induced by moxi-tar.
