Blacklist-based tools are most commonly used to effectively detect suspected malicious processes. The blacklist-based tool compares the malicious code extracted from the existing malicious code with the malicious code. Therefore, it is most effective to detect known malicious codes, but there is a limit to detecting malicious code variants. In order to solve this problem, the necessity of a white list-based tool, which is the opposite of black list, has emerged. Whitelist-based tools do not extract features of malicious code processes, but rather collect reliable processes and verify that the process that checks them is a trusted process. In other words, if malicious code is created using a new vulnerability or if variant malicious code appears, it is not in the list of trusted processes, so it can effectively detect malicious code. In this paper, we propose a method for effectively building a whitelist through research that collects reliable processes in the macOS operating system.

When you want to be given the on-line service, their homepage requires sign-up with detail personal information. This collected private information lead to mass data spill by hacking. Especially, this makes terrible social problems that the users who sign up their site are persistingly attacked and damaged by hackers using this information. As methods of the social technologic attacks are simple but based upon human psychology, it is easy that people become a victim in the majority of cases. There is a strategy blocking fishing sites by using the black list for defending these attacks. This tactic, however, has some problems that it isn't possible to handle new fishing sites having a short life-cycle. In this paper, we suggest two solutions to minimize data spill. One marks existing sites with the sign of a reliability measured by a comparison between black list and the white list; therefore, the user check the authenticity about the homepage. The other shut off previously the leaking of private information by sensing a entry of personal information into new sites.

Recently, Phising attack uses trick of URL and sites, and technical concealment method which infiltrates sophisticated malicious code. However, sometimes Phising security technology cannot cover all of Phising methods. Consequently, this research proposes inspection to solve this problem. First, we can install Proxy server for a strong open information exchange of web environment between web servers and clients. Therefore, it compares and analyzes harmful site and Phising URL with White domain list, and filters them. Finally, designs for stable web based information so that we can block Phising with least regulation and active control. So the purpose of this paper is introducing this design system and structure, and inspect them.

With the cultural background of whiteness I did examine the universal meaning of absolute good, the special of psychosis, and the fantastic of femininity and memory/record. As an example I analyzed the symbolic meaning of white used in Korean films. Unconditional goodness, white as a generality: White color in all the films of good-evil confrontation falls into this category. The most obvious and the simplest configuration are the black-white dichotomy. In Nameless Gangster: Rules of Time(2011), The Merciless(2016), Asura: The City of Madness(2016) and The Bad Guys: Reign of Chaos(2019), white is the absolute good but it is not limited to a fair key figure. Paradoxically, black is not given only to the side of absolute evil. White is used to be a flexible visual device that reflects the socio-political situation without changing the meaning of the general good. Psychosis and pills, white as a peculiarity: The visual function that emphasizes sado-masochism in the absolute good and the universal symbol of white extends to psychotic specificities such as hysteria. In all the films creating horror, white symbolizes the mentally disabled and the pill for healing. Femininity and haunted white: White of absolute good is expressed by the socio-cultural tendency of femininity and the black-white contrast of vision is applied to the gender difference. In general the women's sexuality is emphasized in color red, but white is arranged in the background. In TaeGukGi: Brotherhood Of War(2004), 71: Into The Fire(2010), My Way(2011), The Front Line(2011), Roaring Currents(2014), Northern Limit Line(2015), The Battle: Roar to Victory(2019) and Battle of Jangsari(2019), white given to female figures sticks to the traditional femininity such as motherhood, sacrifice and weakness. The concept of specters is applied to desires, memories/records, history, fantasy, virtual/reality and social media images. The film history capturing to list memories and moments brings up the specters of socio-political genealogy. Most of films aiming for socio-political change are its examples and white constituting Mise-en-scene records to remember a historical event in Peppermint Candy(2000), The Attorney(2013) and A Taxi Driver(2017).

Objectives : The purpose of this study is correct the scientific name of Aquilariae Lignum in Korean Herbal Pharmacoepia. Methods : The production areas of Aquilariae Lignum and its trading status with China in Chinese history, Sanscrit-Chinese Translation Sutra, Naming year and the discovered district in main Aquilaria spp., Several nation's Pharmacoepia, The Plant List(TPL), Convention on International Trade in Endangered Species of Wild fauna and flora(CITES) and The International Union for Conservation of Nature(IUCN) were cross-checked. Results : The records in the Jiaozhouyiwuzhi written in the early 2nd century said that Aquilariae Lignum was produced in Vietnam. NanfangCaomuZhuang written in 304 said that Agarwood in Vietnam had white flowers. Vietnam had led production and trading of Aquilariae Lignum until Qing Dynasty. Aquilariae Lignum from Malaysia and Indonesia was not traded with China. In Sanscrit-Chinese Translation Sutra, India Aquilariae Lignum was translated as Vietnam Aquilariae Lignum. Aquilaria malaccensis was discovered from Malay-Peninsular in 1783, and has green or dirty yellow flowers. A. agallocha from North-Eastern India in 1814, white flowers. A. crasssna from Vietnam in 1914, white flowers. A. crassna is different from A. malaccensis in several ways, such as flower, fruit, seed and disribution. In several Nation's Pharmacoepia, A. crassna was a synonym of A. agallocha. But in TPL, CITES and IUCN, A. malaccensis was an accepted name, and A. agallocha was a synonym of A. malaccensis. Conclusions : These results show that the original species of Aquilariae Lignum in Korea Herbal Pharmacoepia should be reversed from A. agallocha to A. crassna Pierre ex Lacomte.

Multicast is the multiparty communication that allows one-to-many communications. There are some multicast applications which are the ways of multiparty communications such as video conference system and white board. This paper proposes a dynamic allocation mechanism of designated receiver by using designated receiver list and a retransmission mechanism with designated receiver for the effective multicasting dta transmission. We designed voice conference system with multicast based on RTP/RTCP. This voice conference system increases the effect of standardization work and enables to exchange reliable standard dta with real time.
