Subjects in this study were divided into category of male and female from 10s to 30s, and category of majors and non-majors to understand preference for BTS’s hair trend color by making them complete surveys. 374 surveys from total 400 surveys were collected for the final analysis. For collected data, I used SPSS 24.0 program. The results are as follows: For general characteristic of the subjects by gender, females (303, 81.0%) range in age from 20s (291, 77.8%); Unmarried was 340 (90.9%); student from job category was 283 (75.7%); beauty major from major category was 294 (78.6%) while non-beauty major was 80 (21.4%). The result of the research to study the hair trend color of idol boy group (BTS), the most popular image, show that the preference of the trend hair color was as following order: ash gray (M=4.02), mat brown (M=3.95), highlighting (ash after bleaching) (M=3.57), pastel pink (M=3.07), light brown (M=2.99), red (M=2.87), pink orange (M=2.70) which means that both genders prefer ash style and that the major has higher preference level than the non-major.
재머를 사용하는 복호 후 재전송 기반 물리 계층 보안의 성능 분석
박솔,공형윤,Park, Sol,Kong, Hyung-Yun 한국인터넷방송통신학회 2018 한국인터넷방송통신학회 논문지 Vol.18 No.3
본 논문에서는 복호 후 재전송 기반의 중계기 시스템에서 재머를 사용했을 때의 보안 불능 확률을 연구한다. 물리 계층에서 보안 용량을 증가시키기 위해서 선택되지 않은 중계기들 중에서 재머를 선택하여 의도적인 잡음을 발생시키도록 할 수 있다. 재머에 의한 잡음은 수신자와 도청자에서 동일하게 간섭으로 작용하지만 송신자-도청자 링크 간의 채널 품질을 송시자-수신자 링크의 채널보다 더 악화 시키는 최적의 재머를 선택하여 물리 계층 보안을 강화할 수 있다. 본 논문에서는 재머의 유무에 따른 보안 불능 확률의 이론적인 식을 계산하고, 그 식이 타당한지 증명하기 위하여 이론값과 모의실험을 통한 실험값을 비교해 본다. In this paper, we study the secrecy outage probability when using jammer in a relay system based on decode-and-forward. The jammer may be selected among the relays not selected to increase the security capacity in the physical layer so as to generate intentional noise. Jammer noise can equally interfere with the receiver and eavesdropper but can enhance the physical layer security by selecting an optimal jammer that makes the channel quality between the sender-eavesdropper links worse than the channel of the sender-receiver link. In this paper, we compute the theoretical formula of the secrecy outage probability with and without jammers, and compare the theoretical value with the simulation value to prove that the equation is valid.
주파수 정보 활용 및 샘플링 재사용을 통한 Neighbor2Neighbor의 성능 개선
정이삭(Isaac Jeong),박솔아(Sol-A Park),이혁재(Hyuk-Jae Lee) 대한전자공학회 2023 대한전자공학회 학술대회 Vol.2023 No.11
Studies on an unsupervised learning model for image denoising problem are underway and Neighbor2Neighbor(NB2NB) is one of the popular methods for the task. In this paper, we analyzed the limitations of the model, and pointed out two main defects. First, some distortion of data occurs when training due to the loss of information during the sampling process. Second, the expressive power of the network is not sufficient for diverse frequency regions. In order to overcome these limitations, a method of reusing discarded pixels in the sampling process as a regularization term and extending the network structure according to the frequency domain was proposed. It was proved quantitatively and qualitatively that the model that applied these methods, F-NB2NB, has the effect of increasing the performance of NB2NB.
우리나라 지역약국 약사의 위법 행위에 대한 법원의 판례 고찰

Registered pharmacists are required to comply with current laws related to pharmacist practice. This study investigated the precedents of community pharmacists’ misconduct. The cases disclosed to the public on the Korean court’s websites (Comprehensive Legal Information website and Major Court Rulings website) were searched in April 19, 2021, using a keyword “pharmacist”. The selection criteria included case pronounced after July 2000 (implementation of the separation of prescription and dispensing), case that pharmacists was the plaintiffs or the defendants, and case that violated the Pharmaceutical Affairs Act or the National Health Insurance Act. For nineteen cases finally selected which satisfied with eligibility criteria, detailed information for each case were collected from the websites. Based on the provisions of related laws, misconducts of those cases were classified into seven categories: Four cases of license lending, seven cases of illegal drug dispensing and sales, two cases of collusion with medical institutions, two cases of violations of medication guidance obligations, one case of indiscriminate sales of medicines liable to misuse or abuse, two cases of unfair customer inducements, and one case of rebate and undue pressure exercise. The most frequent misconduct types were unfair receipts of medical care benefits and dispensing or sale of medicines by unqualified persons. Learning about the precedents shown in this study is expected to be an guide for individual pharmacists to increase their sensitivity to ethics and compliance with the laws and to be careful about the possible violations in advance.
