The purpose of the study was to perform trend analysis of the exercise content i.e. element difficulty distribution scores, element group distribution scores obtained by the athletes during 2014 Korea Cup International Gymnastic finals. The conclusion drawn from the analysis are as follows: Firstly in terms of tournament technical difficulty value, Korean athletes showed characteristics of reliance on swing element rather than strength hold element which could actually secure higher difficulty scores. Secondly, skill acquisition of higher difficulty value is demanded by taking advantage of familiar characteristics from the swing element i.e. Jonasson and Roll bwd. Slowly with str. arms and body to swallow (2s.). Thirdly, development of sensory training and strengthening exercise program are essential to enhance strength hold technique.

The wave of democratization that started in southern Europe spread to South America and Asia, dismantling the Soviet Union and Eastern European countries and appeared as a Jasmine revolution in countries of North Africa and the Middle East. As a result, many scholars have actively carried out researches related to the sudden change of North Korea, while taking a cautious view that the Jasmine Revolution might occur in North Korea. The focuses of the studies were on the cause and timing of the sudden change and the main forces of the revolution in North Korea. There weren't enough discussions on how the process will be developed and whether there will be a system change. In this study, based on the results of analyzing the systematic changes of the Jasmine revolution nations, it suggested five scenarios that can be developed after the sudden change of North Korea. Scenario type I: Relatively peaceful and the possibility of regime change, Scenario type II: Reunification and then civil war, Scenario type III: Regime changed but one of Kim Il Sung family grabbing the power, Scenario type IV: Successful regime change but civil war happening, Scenario type V: Regime change failed and civil war continuing.

The purpose of this study is provide appropriate arms control measures between South and North Koreas by comparing and analyzing the former proposals and agreements in the past and the current Moon Government's approach representing the 9.19 military agreement. For this, I established the most appropriate framework for analysis through comparing and analyzing the arms control theories. The policies of the past governments and of the current Moon Jae-in government are analyzed. The most highlighted characteristic was that the arms control policies were projected by not from the military confidence, but political confidence building measures or both concurrently. In conclusion, I suggested the strategies of projecting confidence building measures and arms control or disarmament in the process of projecting the peace settlement. Nonetheless, the most important point is that the policies of arms control and unification should be pushed ahead complementally.

Connectivity and knowledge are the main keywords of the IoT. In this paper, I analyzed how the two civilizations, Christianity and Islam, were connected through Mughal paintings and what result they have brought in the spread of knowledge. For that, I analyzed literature as well as paintings of those days. In terms of theme matter, Western painting was used as a means of strengthening the royal authority of the Mughal Emperor. In terms of style, perspective and shading from the Western Paintings began to be used in Mughal painting. Later, Christian symbols and themes were linked to absolute power of kingship, and further utilized them to develop into the concept of kingship = spirituality = divinity, creating an original art style that was unprecedented in the history of world painting. By analyzing the two disparate cultures in terms of 'connectivity' and 'knowledge' of the Internet of Things, such research could serve as a platform for future humanities research on the Internet of Things.

BACKGROUND/OBJECTIVES: The scientific evidence of a sodium-obesity association is limited by sodium intake assessments. Our specific aim is to synthesize the association between dietary sodium intake and obesity across the sodium intake assessments as evidenced by systematic reviews in adults. SUBJECTS/METHODS: A systematic search identified systematic reviews comparing the association of dietary sodium intakes with obesity-related outcomes such as body mass index (BMI), body weight, waist circumference, and risk of (abdominal) obesity. We searched PubMed on October 24, 2022. To assess the Risk of Bias in Systematic Reviews (ROBIS), we employed the ROBIS tool. RESULTS: This review included 3 systematic reviews, consisting of 39 unique observational studies (35 cross-sectional studies and 4 longitudinal studies) and 15 randomized controlled trials (RCTs). We found consistently positive associations between dietary sodium intake and obesity-related outcomes in cross-sectional studies. Studies that used 24-h urine collection indicated a greater BMI for those with higher sodium intake (mean difference = 2.27 kg/m²; 95% confidence interval [CI], 1.59-2.51; P < 0.001; I² = 77%) compared to studies that used spot urine (mean difference = 1.34 kg/m²; 95% CI, 1.13-1.55; P < 0.001; I² = 95%) and dietary methods (mean difference = 0.85 kg/m²; 95% CI, 0.1-1.51; P < 0.05; I² = 95%). CONCLUSIONS: Quantitative synthesis of the systematic reviews has shown that cross-sectional associations between dietary sodium intake and obesity outcomes were substantially different across the sodium intake assessments. We need more high-quality prospective cohort studies and RCTs using 24-h urine collection to examine the causal effects of sodium intake on obesity.

Web 2.0 is a platform which produce various service offered data from many people and it is activity open space depend on user focused community in diversity web environment. Web 2.0 is simple link structure with web site connectivity in informations such as page to page in other words, it is meaning of developing of semantical and circumstantial connection. The core of web 2.0 is user participation. RSS, Mash-up, UCC are main service of web 2.0 which make user directly participate from center of service offer to center of user manufactured an informations and then they offer re-information to other areas, also user freely express what they want through UCC and blogger. However, recently it comes the argument of skeptic of web 2.0 problem. Thus, In this research I will try to give an right comprehension and will try to have more accurate prediction of web 2.0 with the study of open service of web which is the key of web 2.0 success in a future.

The purpose of the study is to investigate the convergence comparison of the stress, major satisfaction, career identity, and college adjustment of nursing students according to college admission process and grade. The 349 subjects were studying in the nursing department in the City P. And the data collection was carried out from April 2016 until May 2016. The data analysis was carried out with the frequency, the percentage, the ${\chi}^2$-test, and the ANOVA by using the SPSS 23.0 Program. Regarding the research results, first, there were no significant differences among the entire academic years according to the admission type. Second, regarding all the admission types according to the academic year, there were the significant differences among stress (p=.001), the degree of satisfaction with the major (p<.001), the sense of career path identity (p=.021), and the adaptation to the college life (p<.001). As a result, I propose that, based on these results of the research, as a strategy for reducing the stress and for improving the degree of satisfaction with the major, the sense of career path identity, and the capability to adapt to the college life on the part of the nursing students, a differentiated, customized educational program by type of admission and by academic year should be developed and applied.

Reactive oxygen species (ROS) damage DNA and cause cancer. Therefore, the research is being conducted on the development of antioxidants for the removal of ROS. This study was performed to investigate antioxidant activity and protective effect against oxidative DNA damage using ethyl acetate fractions from the cone of Pinus rigida × taeda (ERT). The antioxidant activity was evaluated using the DPPH, ABTS radical scavenging assay, reducing power assay, and Fe2+ chelating assay. Also, the contents of phenolic compounds and vitamin C related to antioxidant activity were analyzed to confirm phytochemicals. The DNA protective effect against oxidative stress was confirmed by the φX-174 RF I plasmid DNA cleavage assay. As a result, ERT showed DPPH and ABTS radical scavenging activities in a concentration-dependent manner. The results of reducing power and Fe2+ chelating activities were 77.32 ± 2.28% and 64.09 ± 1.01% at 200 ㎍/㎖. Also, ERT showed a DNA protective effect against oxidative stress.
