Objectives : Recently, the number of elderly people has been rapidly increasing in Korea, and it led to increase demands of Korean traditional medical services. However, there is a lack of information on Korean traditional service utilization. Thus, this study was intended to identify Korean traditional service utilization patterns such as acupuncture, moxibustion and cupping, since Korean traditional services were specially used in treating chronic diseases for elderly people. It is important to understand health services utilization for quality improvement of healthcare systems. Methods:We used data of 'Survey in Daegu' in 2008 and analyzed characteristics of disease structure and utilization patterns of health care service of 1,097 cases of participated citizens. Results : The proportion of the elderly people (>50 age) in total participators is 52.4%. Male to female ratio is 1:1.65 and most common age group was between 50 and 59 years old. 84.2% of participators were admitted at oriental health care facilities. In addition, the results showed that female were more used the service than man. The most common treated disease is musculoskeletal disorders in both male and female. Conclusions : Acupuncture, moxa and cupping are widely used to treat chronic degenerative diseases such as musculoskeletal disorders at oriental health care facilities. Elders and female prefer to be admitted at oriental health care facilities.

방선균에서 DNA 전사 억제인자로써 작용하여 이차대사산물의 생산뿐만 아니라 형태분화를 조절하는 $\gamma-butyrolactone$ autoregulator receptor를 암호화하는 유전자(scaR)를 clavulanic arid 생산 균주, Streptomyces clavuligerus로부터 클로닝하고 in vitro에서 ScaR의 특징을 연구하여 보고한 바 있다. 따라서 본 연구에서는 ScaR의 in vivo 기능을 분석하기위해 상동재조합방법을 이용하여 scaR이 제거된 변이주를 제작하고 야생균주와 표현형을 비교해 보았다. 그 결과, Streptomyces clavuligerus의 형태분화에서는 큰 차이를 나타내지 않았지만 clavulanic acid의 생산에 있어서는 scaR 파괴 변이주가 야생균주에 비해 생산이 증가된 경향을 보였다. 그러므로 ScaR이 S. clavuligerus의 형태분화에는 영향을 미치지 않지만 clavulanic acid 생합성에는 negative regulator로 작용한다는 것을 본 연구를 통해 명확하게 확인할 수 있었다. A $\gamma-butyrolactone$ autoregulator receptor has a common activity as DNA-binding transcriptional repressors controlling secondary metabolism and/or morphological differentiation in Streptomyces. A gene (scaR) encoding it was cloned from Streptomyces cravuligerus, a clavulanic acid producer, and was in vitro characterized in a previous report. In this study to clarify the in vivo function of ScaR, a $\gamma-butyrolactone$ autoregulator receptor of Streptomyces clavuligerus, we constructed a scaR-deleted strain by means of homologous recombination. No difference in morphology was found between the wild-type strain and the scaR-disruptant, but the scaR-disruptant showed higher clavulanic acid production. This indicates that the ScaR in S. clavuligerus acts as a negative regulator of the biosynthesis of clavulanic acid, but plays no role in morphological differentiation.

Objective : Solar ultraviolet (UV) light can cause photoaging of human skin. Many researchers have focused on effective prevention to mitigate the aging process. This study was aimed to investigate anti-wrinkle effects of pomegranate concentration solution (PCS) using photoaged hairless mouse model. Method : To clarify the protective effect of PCS against UVB-induced photo-damage, water capacity was measured with transepidermal water loss (TEWL) in SKH-1 hairless mice. In addition, image of skin replicas was analyzed. Results : Our results showed that the PCS treatment protects skin against UVB-induced photoaging, based on the parameters including moisture capacity and TEWL. According to visual assessment of skin replica, application of 1 ml/kg PCS inhibited UV-induced wrinkle formation in mice skin as compared to the vehicle-applied control mice. Conclusion : Taken together, these results indicated that PCS could improve skin wrinkle formation induced by UVB irradiation in SHK-1 hairless mice. PCS could be applied as an anti-wrinkle agent.

Objective : Recently the number of health functional food (HFF) made with Traditional Korean Medicine (TKM) herbs have been increasing. However, there was a lack of the functional and safety information on HFF. Thus, this study was performed to investigate perceptions and consumptions of the HFF in Daegu area. Method : We used the data of 'Survey in Daegu' in 2010 and analyzed characteristics of perceptions and intake conditions of HFF of 1,208 participated inhabitants. Result : Among the 1,208 respondents, 30.4% were male and 63.5% were female. Most respondents (69.3%) were between 30's and 50's decade. The recognition rate of HFF made with TKM herb appeared to 86.2%. The major route of acquiring HFF information was 'mass-media' (49.8%) ; the primary reason of using HFF was 'For health promotion and anti-aging' (69.2%). On the other hand, the recognition rate of adverse effects was 53.3%. As for intake effect, 41.5% were satisfied at HFF consumption, while 56.0% did not feel special effects through the HFF consumption. In regards to purchase place, 'HFF store' was most selected by 38.0%. 69.1% of respondents selected to TKM decoction, the reason is that it made according to TKM physician's diagnosis considered their health condition. Conclusion : HFF intake was purpose to health promotion, but HFF made with TKM was consumed without any information about that. In order that HFF be used properly to promote health, the scientific and reasonable information of HFF made with TKM herb is need for consumers.

This study analyzed the effect of urban-rural integration features on the fear of crime using multilevel ordered logistic model. As a result of the analysis, this study identified that the individual characteristics are important factors that affect the fear of crime, and in particular, it is found differences in perception of the fear of crime according to gender. Next, the result was derived that urban and rural integration feature was the most important factor affecting the fear of crime, excluding gender. In addition, this study confirmed that the increase in rural areas aggravates the fear of crime, while the increase in urban areas mitigates the fear. Based on these conclusions, this study produced the following policy implications. First, the crime prevention through environmental design (CPTED) must be applied when promoting the urban-rural integration process. Second, it will have to actively accept second-generation CPTED plan which focuses not only on improving the physical environment but also on enhancing residents’ participation and ties. Third, the expansion of CPTED facilities in rural areas should be considered first.

강수진(Soojin Kang),이세훈(Sehoon Lee),김소람(Soram Kim),김대운(Daeun Kim),김기문(Kimoon Kim),김종성(Jongsung Kim) 한국정보보호학회 2021 정보보호학회논문지 Vol.31 No.2

랜섬웨어는 악성 소프트웨어로 컴퓨터에 저장된 데이터를 암호화하여 접근을 제한하고, 사용자에게 접근 권한을 대가로 금전을 요구한다. 최근 랜섬웨어는 대칭키 또는 스트림 암호 알고리즘을 사용하여 피해자의 파일을 암호화하고, 해당 암호키를 공격자의 공개키로 암호화하는 하이브리드 암호 시스템을 사용한다. 대부분 랜섬웨어는 파일 암호화 시 안전하다고 알려진 AES 알고리즘을 사용하며, 일부 랜섬웨어에서 Salsa20과 같은 스트림 암호를 사용한 경우도 발견된다. 모두 안전성이 확인된 알고리즘이지만, 공격자가 잘못 설계하는 경우 암호학적 취약점이 발생한다. 2019년 하반기에 등장한 Ragnar Locker 랜섬웨어는 하이브리드 암호 시스템을 사용하지만, 파일 암호화 시 스트림 암호에 동일한 키를 반복 사용함으로 취약점이 발생했다. 본 논문에서는 키 재사용 공격을 활용하여 공격자의 개인키 없이 감염된 데이터의 복호화 방안과 해당 취약점을 활용할 수 있는 방안을 제시한다. Ransomware is malicious software that restricts access by encrypting data stored in a computer, and demands money in return for access rights. Ransomware has recently been using a hybrid encryption scheme that combines both symmetric and asymmetric algorithms. The symmetric system is for the encryption of files of a target system and the asymmetric system is used to encrypt the symmetric key. Most ransomware uses the AES algorithm but some use a stream cipher such as the Salsa20. These algorithms are secure however the vulnerability is caused by cryptographic design flaws. Ragnar Locker Ransomware, which appeared in the second half of 2019, uses a hybrid cryptographic system, however, it is vulnerable by reusing the same key when encrypting the files. In this paper, we propose a method of decrypting infected data without a private key of the attacker by utilizing a key reuse attack and a way to apply for other applications.
