  • In planning a model-based phylogenic study for highly related ethnic data, the SNP marker number is an important factor to determine for relationship inferences. Genotype frequency data, utilizing a sub sampling method, from 63 Pan Asian ethnic groups was used for determining the minimum SNP number required to establish such relationships. Bootstrap random sub-samplings were done from 5.6K PASNPi SNP data. DA distance was calculated and neighbour-joining trees were drawn with every re-sampling data set. Consensus trees were made with the same 100 sub-samples and bootstrap proportions were calculated. The tree consistency to the one obtained from the whole marker set, improved with increasing marker numbers. The bootstrap proportions became reliable when more than 7,000 SNPs were used at a time. Within highly related ethnic groups, the minimum SNPs number for a robust neighbor-joining tree inference was about 7,000 for a 95% bootstrap support.

  • Asian populations contain a variety of ethnic groups that have ethnically specific genetic differences. Ethnic variants may be highly relevant in disease and human differentiation studies. Here, we identified ethnically specific variants and then investigated their distribution across Asian ethnic groups. We obtained 58,960 Pan-Asian single nucleotide polymorphisms of 1,953 individuals from 72 ethnic groups of 11 Asian countries. We selected 9,306 ethnic variant single nucleotide polymorphisms (ESNPs) and 5,167 ethnic variant copy number polymorphisms (ECNPs) using the nearest shrunken centroid method. We analyzed ESNPs and ECNPs in 3 hierarchical levels: superpopulation, subpopulation, and ethnic population. We also identified ESNP- and ECNP-related genes and their features. This study represents the first attempt to identify Asian ESNP and ECNP markers, which can be used to identify genetic differences and predict disease susceptibility and drug effectiveness in Asian ethnic populations.

  • MQV 프로토콜은 가장 효율적인 Diffie-Hellman 키 교환 프로토콜로 여겨지고 있으며, 미국 NSA를 비롯한 많은 기관들에서 표준으로 채택되었다. Crypto 2005에서 Hugo Krawczyk는 MQV의 약점들을 보였으며, MQV를 변형한 HMQV를 제안했다. HMQV는 MQV와 비슷한 계산량을 요구하는 반면 다양한 안전성을 만족하며, 랜덤 오라클 모델에서 안전성 증명이 가능하다. 이 논문에서 HMQV가 제공하는 다양한 안전성을 만족하면서도 랜덤 오라클을 사용하지 않는 Diffie-Hellman 키 교환 프로토콜을 제안한다. 지금까지는 랜덤 오라클을 사용하지 않으면서 HMQV가 제공하는 다양한 안전성을 보장하는 Diffie-Hellman 키 교환 프로토콜은 존재하지 않았다.

  • The purpose of this paper is to reconsider and revaluate Ste. Genevieve Library designed by Henri Labrouste as a criticism of Classicism. Considered as the epitome of the early structural Rationalism the modern historian tried to focus only on the iron structure of the library. Arguably, the structural concern was one of the ideas that the architect wanted to manifest in the library. As a rebel against a view of the Acad$\acute{e}$mie des Beaux-Art the notions of H. Labrouste were radical. He criticized an autistic Classicism with an echoing Claude Perrault's doubt about the myth of classical beauty. These radical ideas firstly showed in his report of the Grand Prix de Rome and must have been developed through several discussions for a novel: Notre-Dame de Paris by V. Hugo. 'Ceci tuera cela', one of the chapter of the novel, was generally known as the death of architecture due to the invention of the printing press around Renaissance period. We, however, consider that even though the historical background of the novel is the Gothic period the ideas, which was discussed with Labrouste, related to the death of architecture was not the architecture itself but classical architecture recomposed during Renaissance period. As the first design work the library must be reflected his ideas, which were developed, and manifested his criticism of the Classicism indirectly.

  • Purpose: Personality qualities are essential to the prosperity of any contemporary company because they foster the growth of pleasant emotions in telecommunications distribution employees. Research design, data and methodology: Thus improving their overall psychological well-being and productivity. Talent retention is facilitated by mutual respect between management and staff. The success of the company as a whole, including the development and maintenance of emotions with customers, also depends on the psychological well-being of employees. The aim is to demonstrate how a positive and satisfied emotional workforce contributes to psychological well-being in the 21st century. Result: The research aims to better understand the personality traits that influence the psychological well-being of employees. In addition, between January and March 2023, a total of 179 employees in the telecommunications distribution industry in the Peruvian city of Chiclayo were surveyed using structural modelling methods to measure employee satisfaction. It also shows how various ideas, approaches and models can be used in the real world. Conclusion: The significance of the model on the perception of telecommunications workers in Peru is demonstrated by the results, which indicate an R2 value of 0.681 for positive emotions and an R2 value of 0.792 for employees' psychological well-being.

  • The purpose of this study is not to understand functionalism from a simple program or effectiveness and economic perspective, but to reinterpret from a substantial perspective that modern architects assert commonly and to apply it to hospital design in a new way.
