With the emergence of advanced encryption technologies such as Quantum Cryptography and Full Disk Encryption, an era of strengthening information security has begun. Users respond positively to the advancement of privacy-enhancing technology, on the other hand, investigative agencies have difficulty unveiling the actual truth as they fail to decrypt devices. In particular, unlike past ciphers, encryption methods using biometric information such as fingerprints, iris, and faces have become common and have faced technical limitations in collecting digital evidence. Accordingly, normative solutions have emerged as a major issue. The United States enacted the CLOUD Act with the legal mechanism of 'Contempt of court' and in 2016, the United Kingdom substantiated the Compelled Decryption through the Investigatory Powers Act (IPA). However, it is difficult to enforce Compelled Decryption on individuals in Korea because Korean is highly sensitive to personal information. Therefore, in this paper, we sought a method of introducing a Compelled Decryption that does not contradict the people's legal sentiment through a perception survey of 95 people on the Compelled Decryption. We tried to compare and review the Budapest Convention with major overseas laws such as the United States and the United Kingdom, and to suggest a direction of legislation acceptable to the people in ways to minimize infringement of privacy. We hope that this study will be an effective legal response plan for law enforcement agencies that can normatively overcome the technical limitations of decoding.

Through this incident, it reminds me of the idea that personnel appointments are everything once again. Public officials should try to be good at ethics and conduct. If a public official fails to fulfill his or her role as a public official, how can the public trust him or her? You should know that the country does not exist under that official. Looking back on the constitutional history after liberation, it is undeniable that the collusion between politicians and businessmen shocked the people with many suspicions and distrust, and the various irregularities they caused disrupted healthy democracy and the national economic order. In this respect, this paper focuses on Korean political reform measures, but also examines ways to improve public officials' ethics. This paper focuses on that political reform should move in the direction of revitalizing the function of the National Assembly and allowing autonomous and independent parliamentary activities. Parliamentary activities should not be too dampened, and it should not end in a brief promotion in consideration of election votes. The ruling and opposition parties should seriously consider and implement this political reform plan. As one of the people, I hope that this privilege reform plan can be a touchstone for the advancement of political culture. This paper was studied as follows. First, the purpose and justification of political reform were identified. Second, it emphasized the need to improve public service ethics. Third, the problems and improvement measures of political reform were considered.

공인인증서의 사용은 꾸준히 증가하고 있으나 증가하는 사용량에 비례하여 하드디스크에 저장된 공인인증서 해킹으로 인한 피해 사례가 증가하고 있다. 이에 따라 정부는 하드디스크 내 공인인증서 저장을 금지하고 이동형 저장매체에 저장하도록 하는 방침을 내놓았다. 또한 모바일 클라우드 컴퓨팅 환경에서는 중앙의 스토리지에 데이터가 저장되기 때문에 공인인증서를 중앙 스토리지에 저장하는 것은 매우 위험한 일이다. 이러한 방침으로 인해 앞으로 USB 메모리 및 스마트폰과 같은 이동형 저장매체에 대한 중요성이 높아질 것이며, 분실 위험이 높은 USB 메모리 및 스마트폰의 특징에 따라 인증서가 저장된 저장매체 없이도 인증서를 사용할 수 있는 방안이 필요하게 될 것이다. 본 논문은 일회용 인증서에 대한 요구사항 분석 및 형식을 설계하고, PKI 인증서를 기반으로 경량화된 일회용 인증서를 발급받아 인증서를 사용할 수 있도록 하였다. 또한 모바일 클라우드 컴퓨팅 환경에서 일회용 인증서를 이용한 권한 관리 기술을 제안하여 안전성과 효율성을 제공하도록 하였다.

Takji-oryego (A Review of the Five manners related to the Ministry of Finance) is a book organized by Hojo (Joseon's Ministry of Finance) and the cost and details of royal events held according to five manners. This book contained a lot of information on medicine-related rituals in the late Joseon Dynasty. Thus, it was found that the royal rituals related to medicine include not only childbirth and fertility, but also Heuljeon and Sangjeon. Through this study, the following facts were newly discovered: 1) The time of transcription was between October 1840 and October 1841. 2) Huljeon (Privilege given to save) is also related to the rise of the status of medical officials after King Sukjong. 3) According to Heuljeon, medical bureaucrats in the late Joseon Dynasty had a higher position than other technical officials. 4) The contents of reward were complementary to the existing literature. The date of death of a medical official, which was unknown in previous studies, is documented. In a case like Sansilcheong, there are contents that are unknown through other sources.

There are increasing reports regarding regeneration of the defected tissues using tissue engineering technique. In this technique, multipotential stem cells are essential. There are many potential sources of adult stem cells, such as bone marrow, umbilical cord blood, fat, muscle, dental tissues and skin. Among them, skin is highly accessible and easily obtained with a minimum of donor site complications. Moreover, skin is an abundant adult stem cell sources and has the potential for self-replication and immune privilege. In this study, we isolated skin-derived precursor cells (SKPs) from the ear of adult miniature pigs. In these SKPs, the expression of transcriptional factors, Oct-4, Sox-2, and Nanog were detected by RT-PCR. In vitro osteogenesis and adipogenesis were observed at 3 weeks after transdifferentiations as assayed by positive von Kossa and Oil-red O staining, respectively. In addition, expression of osteocalcin and osteonectin in the osteogenic differentiation medium and $PPAR{\gamma}2$ and aP2 in the adipogenic differentiation medium were detected by RT-PCR. In vitro neurogenesis of porcine SKPs was observed during 24 and 72 hours after treatment of neurogenic differentiation medium. The results of this study suggest that SKPs demonstrate the properties of pluripotence or multipotence and multi-lineage differentiation. This indicates that autogenous SKPs are a reliable and useful source of adult stem cells for regenerative medicine.

The purposes of this study are to examine the concept of customized fashion product design as a new industrial paradigm reflecting individual customers' needs in modern society, and to grasp its sociocultural meaning. It is thought that this study will be helpful to investigate the cultural thinking of contemporaries represented through the consumption. For this, the documentary study and practical case study have been executed. As modern fashion business becomes more consumer-oriented due to the industrial paradigm shift, there appeared the prosumer as both consumer and producer. The type of customized fashion product design can be classified as 1) the traditional custom-made design in haute couture and classic tailoring 2) the tailor-made design in the prestige line of ready to wear 3) DIY custom design 4) mass customized design of customer involvement. The traditional custom-made design in haute couture and classic tailoring and the tailor-made design in the prestige line of ready to wear is to provide the distinguished product which has the best quality as well as the excellent beauty for VIP consumer. The DIY custom design is for creative consumer searching for the fun of craftsmanship to take part in producing personally. The mass customized design of customer involvement is to personalize product by selecting design module in mass production. Ultimately the sociocultural meaning of the customized fashion product design can be interpreted as (1)endowing special meaning to personal identity (2)distinguishing the privilege by rarefied authenticity (3)returning to analog sensibility 4)pursuing creative fun 5)thinking in a user-centered way.
