  • Objectives: Following the Jin Yuan Dynasty, the Ming and Song Dynasties witnessed a great development of Yunqi xue. A study into this development has a vast significance in studying the history of the development of traditional Chinese medicine. Methods: The contents relating to Yunqi within the Comprehensive Medical Books, published during the Ming period, and medical texts separately published specifically dealing with Yunqi were used in order to review the unique characters of the study of Yunqi during this period. Results: There were many cases in the comprehensive medical books during the Ming period that dealt with Yunqi. Some of the examples are: Yunqilu in Yixueliuyao, YunQiZongLun in Yixuerumen, and Yunqilu in Yixueliuyao. A number of books that followed suit from the previous generation's study were published, the examples of which are Wangji's Yunqiyilan, and ZhangJiebin's LeiJingtuyi. WangJi, in his book, opposed the mechanic utilization of YunQi theory, and advocated the flexible application of the theory at the doctor's discretion. Liwei, in his YunQiZongLun, wrote a great deal of knowledge which he gained based on the previous-generation medical masters' achievements. Conclusions: Yunqi became widely accepted during the Ming period which led to some doctors advocating the flexible application of the YunQi theory, and some doctors even completely denouncing Yunqi.

  • Test pattern generation is one of most difficult problems encountered in automating the design of logic circuits. The goal is to obtain the highest fault coverage with the minimum number of test patterns for a given circuit and fault set. although there have been many deterministic algorithms and heuristics the problem is still highly complex and time-consuming. Therefore new approach-es are needed to augment the existing techniques. This paper considers the problem of test pattern improvement for combinational circuits as a restricted subproblem of the test pattern generation. The problem is to maximize the fault coverage with a fixed number of test patterns for a given cir-cuit and fault set. We propose a new approach by use of a genetic algorithm. In this approach the genetic algorithm evolves test patterns to improve their fault coverage. A fault simulation is used to compute the fault coverage of the test patterns Experimental results show that the genetic algorithm based approach can achieve higher fault coverages than traditional techniques for most combinational circuits. Another advantage of the approach is that the genetic algorithm needs no detailed knowledge of faulty circuits under test.

  • Recently, it is one of the popular fashion and cultural events that people of the younger generation put on a hanbok and take a picture together with communicating by SNS. For this reason, the rent-hanbok market takes a big part of the Korean traditional costume market. Therefor, the recognition of hanbok is changed from the style of uncomfortable and ceremonial clothes, to becoming popular as everyday dress in the younger generation. The various designs of the rental hanbok show two different opinions. One is the increasing popular and general public interest and demand for wearing and showing off traditional hanbok fashions in a positive outlook. Another is the case of the wrong stereotype and knowledge for traditional costume which results in a negative outlook for this type of fashion statement. This study is to look into renting hanbok jeogori for women in Seoul and in Junju. There are 39 styles available in joegori. That being noted, the traditional jeogori has seop and git with dongjung. But it is seen that rental jeogoris do not have the seop, or have the dongjung position as similar to the Po as seen on the men's coat. The showy and colorful materials feel bad and are poorly ventilated. And excessive price competition causes a decreased quality of renting hanbok. Now the rental hanbok business needs to change; to have to make renting hanbok with the correct historical understanding, and it is necessary to have to stop the indiscriminate acceptance of foreign culture.

  • The role of the social environment for any activity is crucial as it prompts new ideas and plays a role of lever for entrepreneurial longevity and creating value through social wellbeing. The lack of entrepreneurship related knowledge in Pakistan has taken the challenge of lesser entrepreneurial activity as compared to other counterpart Asian countries and ranked 138 out of 189 countries on the level of ease of doing business. The study aims to investigate the social environment as a mediator among idea generation, business creation, financing decision and entrepreneurial activity by utilizing quantitative approach. In order to achieve the objective, a total of thirty eight items scale was self-administered for data collection. A non-probability, snowball sampling technique was employed and assembled a total of 300 complete responses through online and paper based surveys as per information provided by the chamber of commerce of three regions namely; Sukkur, Hyderabad and Karachi Sindh, Pakistan. The data analysis result strongly supported the main research question as the entrepreneurial activity increased up to 43.8% after applying social environment as a mediator. This research can help to enhance entrepreneurial activities in Pakistan by creating awareness to support entrepreneurs at social level for entrepreneurship.

  • As the penetration of information technology into everyday life is accelerated day by day, virtually all kinds of human representation of knowledge and arts are produced and distributed in the digital form. It is problematic, however, because digital objects are so volatile that it is not easy to keep them in fixed form. The fatal fragility makes it extremely tricky to preserve the digital heritage of our time for the next generation. The present paper aims to introduce current endeavors made at the international and the national levels and to provide with suggestions for Korean national strategy of digital preservation. It starts with reviewing the global trends of digital archiving and long-term preservation, focusing on standardization, preservation strategies and current experiments and projects being conducted for preserving various digital objects. It then sketches national strategies of several leading countries. Based on the sketch, twofold suggestions for Korean national strategy are proposed: establishing a central coordinating agency and accommodating the digital preservation issue in the legislative and regulatory framework for the information society. The paper concludes with the necessity of cooperation among heritage organizations, including libraries, archives, museums. They should cooperate with each other because they have traditionally been trusted with the custodianship of collective memory of humankind and the digital heritage cannot be passed onto the next generation without their endeavor. They should also work together because any single institution, or any single nation could cover what it takes to complete the task of long-term preservation of our digital heritage.

  • The fragmentation statistics of ion trap CID (Collision-Induced Dissociation) spectra using 87,661 tandem mass spectra of doubly charged tryptic peptides are analyzed here. In contrast to the usual method of using intensity information, the frequency of occurrence of fragment ions, with respect to the position of the cleavage site and the residues at these sites is studied in this paper. The analysis shows that the frequency of occurrence of fragment ion peaks is more towards the middle of the peptide than its ends. It was noted that amino acid with an aromatic and basic side chain at N- & C- terminal end of the peptide stimulates more peaks at the lower end of the spectrum. The residue pair effect was shown when the amide bond occurs between acidic and basic residues. The fragmentation at these sites (D/E-H/R/K) stimulates the generation of the y-ion peak. Also, the cleavage site H-H/R/K stimulates the generation of b-ions. K-P environment in the peptide sequence has more tendency to generate y-ions than b-ions. Statistical analysis helps in the visualization of the CID fragmentation pattern. Cleavage pattern along the length of the peptide and the residue pair effects, enhance the knowledge of fragmentation behavior, which is useful for the better interpretation of tandem mass spectra.

  • The purpose of this research is to investigate the impacts of gen-Z's perception of consumer-generated content on social media on their travel intention with the mediating role of travel motivation push and pull. An online questionnaire survey of a total of 369 samples was conducted with the participation of gen Z in the most important cities across Vietnam. The model was analyzed using Structural Equation Modeling (SEM) using AMOS program 22 to investigate model relationships and all hypotheses are significant. The findings indicated that gen Z values the usefulness of social media and they use social media for knowledge-seeking (push factor), and this leads to their intention to visit a destination. SEM analysis also reveals that gen Z tends to use social media to find accessibility to any destinations and they are motivated highly with destinations that have clear and easy access, for example, no visa requirement or neighboring destinations. As the result, they have better intentions to visit these destinations. This research will help marketers, especially marketing specialists to gain a better understanding of gen Z, thus implement better marketing techniques to target gen Z.

  • South Korea, a country that built a world-class nuclear power infrastructure, shifted to a nuclear phaseout during the previous government's reign. This shift was pursued as part of a larger task of electricity mix reform, and one of the integral motives for such reform is addressing greenhouse gas (GHG) and fine dust problems. Thus, verifying the relationships between the public's concerns about GHG/fine dust and their acceptance of nuclear power generation is essential for designing public communication strategies to revive nuclear power under the ongoing environmental regime. Our analysis using a nationwide survey sample of South Korea (N = 1009, through proportionated quota sampling method) showed that the more people are concerned about GHG and fine dust, the less they accept nuclear power. These relationships held even after controlling for the effect of a third variable-energy-related environmentalism. This finding means that despite past communication efforts positioning nuclear power as a generation source that can mitigate GHG/fine dust emissions and the widely accepted scientific evidence that supports such positioning, nuclear power in Korea is in jeopardy. Our finding provides implications for public communications and fundamental knowledge for research on the determinants of nuclear power acceptance.
