High risk of cardiovascular diseases caused by existing PPAR-${\gamma}$ agonists such as rosiglitazone and pioglitazone has been recently reported. CKD-501 is a novel selective PPAR-${\gamma}$ agonist as a potential target to reduce cardiovascular risk in non-insulin dependent diabetes mellitus (NIDDM). In this study, We investigated potential cardiotoxicity of CKD-501 and compared its toxicity with that of rosiglitazone or pioglitazone using db/db mice. After 12-week repeated administration of CKD-501 at doses of 3, 10 and 30 mg/kg/day or rosiglitazone at doses of 10 and 30 mg/kg/day or pioglitazone at doses of 200 and 540 mg/kg/day, animals were sacrificed for investigation of potential toxicities. Diameters of left ventricles and areas of cardiomyocytes were measured. And lipid accumulation and apoptosis in heart muscle were examined by oil red O staining and TUNEL staining, respectively. Diameters of left ventricles were significantly increased in high dose treatment group of pioglitazone compared to control (p<0.05), while other groups showed a tendency for an increase. All test articles induced significantly the increase of area of cardiomyocytes in heart compared to control (p<0.01), in regular order as pioglitazone > CKD-501 ${\geq}$ rosiglitazone. However, lipid accumulation and apoptotic changes in heart were not observed in all dosing groups. Taken together, the myocardial cell hypertrophy of CKD-501 are relatively lower than that of pioglitazone and similar to rosiglitazone. And it is suggested that the myocardial cell hypertrophy of CKD-501 are less adverse in clinical use for the management of the NIDDM.

The purpose of this study is to know clinical usefulness for fat suppression of the body curved portion compared with TSE-CHESS and TSE-SPAIR technique. A total of 25 normal volunteers without cervical spine disease were studied on a 3.0 T MRI scanner. As a quantitative analysis, PSNRs and CNRs were evaluated by using two methods for fat suppression of the body curved portion. As a results, PSNRs and CNRs for fat suppression were significantly greater for the TSE-SPAIR technique compared to TSE-CHESS technique. In conclusion, this study showed that a TSE-SPAIR technique has improved PSNRs and CNRs for evaluating of fat suppression in the body curved portion. These conclusions in the future will be provided information in diagnosis of fat suppression for the body curved portion.

In sensor network, the importance of transporting data with reliability is growing gradually to support communications. Data flow from sink to nodes needs reliability for the control or management, that is very sensitive and intolerable, however relatively, data flow from nodes to sink is tolerable. In this paper, with emphasis of the data flow from sink to nodes, we proposed the mechanism that establishes confidence interval for transport. Establishing confidence interval herby-hop, not end to end, if errors happen or there's missing data, this mechanism recovers them with selective acknowledgement using fixed window. In addition, this mechanism supports franc congestion control depending on the buffer condition. Through the simulation, we showed that this mechanism has an excellent performance for error recovery in sensor network.

Efforts to build metaverse platform services and expand profit structure are developing in a more realistic direction. The metaverse, which has been centered on 'creation and economy' and 'discovery', will evolve into an 'experience' metaverse, creating tangible business effects where satisfaction with the user experience leads directly to purchase. In this paper, the condition of the avatar used as a medium of economic activity between the metaverse platformer and the user and the business utilization plan were sought. In addition, a new 'metaverse business model' was proposed based on 'experience, discovery, creation and economy', and in particular, it was intended to lay the foundation for the experience metaverse to further develop in the form of 'business experience'. In addition, a survey was conducted on the 'application of metaverse service and avatar' targeting the MZ generation, the main customer base of the current metaverse service. In order to provide a service that satisfies the user, it was concluded that the appearance of the avatar needs to be changed according to the purpose and function. Accordingly, we propose an 'selective switch mode' that can change the avatar's appearance at the desired timing according to the 'experience' and 'purchase purpose' of each metaverse service area. In addition, by strategically utilizing the 'Digilog' psychology, we believe that it will be possible to promote the influx of new users while increasing the loyalty of existing users to the platform. Through the establishment of 'avatar purchase system' by 'selective switch mode' and 'avatar decorating system' by 'digilog' strategy, the experience metaverse, which has been focused on 'digital twin experience' so far, is As it develops into 'business experience', it is expected that the user experience can be further satisfied.

AI semiconductors like GPUs, TPUs, and NPUs are crucial for deep learning models, with High Bandwidth Memory (HBM) enhancing performance. The HBM market is projected to grow annually by 46% from 2022 to 2029. To address challenges in semiconductor packaging, such as heat dissipation and signal interference, 3D-IC stacking and glass interposers with Through Glass Via (TGV) technology are emerging as key solutions. TGV improves thermal management, signal integrity, and cost efficiency. This paper discusses recent research trends in TGV manufacturing technologies, such as selective laser etching (SLE), functional layer deposition, and pulse electroplating, which are core technologies for enhancing the reliability and performance of AI semiconductors. SLE technology allows the formation of vias in glass by selectively removing material from a substrate using a laser and an etchant.

Self-Assembled Monolayers (SAMs) formed by alkanethiol adsorption to thin metal film are widely being investigated for applications as coating layer for anti-stiction or friction reduction and in fabrication of micro structure of molecules and bio molecules. Recently, there have been many researches on micro patterning using the advantages of very thin thickness and etching resistance of Self-Assembled Monolayers in selective etching of thin metal film. In this report, we present the several machining method to form the nanoscale structure by Mask-Less laser patterning using alknanethiolate Self-Assembled Monolayers such as thin metal film etching and heterogeneous SAM structure formation.

Financial markets are characterized by large numbers of complex and interacting factors which are ill-understood and frequently difficult to measure. Mathematical models developed in finance are precise formulations of theories of how these factors interact to produce the market value of financial asset. While these models are quite good at predicting these market values, because these forces and their interactions are not precisely understood, the model value nevertheless deviates to some extent from the observable market value. In this paper we propose a framework for augmenting the predictive capabilities of mathematical model with a learning component which is primed with an initial set of historical data and then adjusts its behavior after the event of prediction.

Massive and untreated hemoptysis is associated with a mortality of greater than 50 percents. Since the bleeding was from a bronchial arterial source in the vast majority of patients, embolization of the bronchial arteries has become an accepted treatment in the management of massive hemoptysis because it achieves immediate control of the patients. We have controlled massive hemoptysis in a case with selective bronchial arteral embolization with Gelfoam.

This study approached the leisure with the step of life cycle, analyzing the process of leisure career and leisure development in individual life. The leisure life cycle leads the other related studies by examining the concepts of continuity, change, leisure socialization, and leisure career. It also analyzes the patterns and the structures of the use of life time, using '2004 Time Use Survey' from the Korea National Statistical Office. As a result, this study suggests new 3 steps of leisure life cycle: participating and expanding stages, selective and concentrating stage, and continuing and absorbed stage. These steps set up the goal of leisure program by the periods. They also can help setting the direction of leisure activities, and can be used as basic data that can make up the leisure activity program models step by step. Moreover, the development of model can be used as valuable information to draw up the plans that can prepare for aging society and demand the support of policy.
