본 논문에서는 SSL/TLS에서 발생할 수 있는 cipher suite rollback 공격 탐지를 위해 선택된 알고리즘을 리스트로 검증하는 방법을 제안한다. 제안 기법은 SSL/TLS의 핸드셰이크 단계에서 이루어진다. 클라이언트 기기가 암호화 알고리즘의 순위를 리스트로 만들고 핸드셰이크가 끝난 후에 선택된 알고리즘의 순위를 비교해서 해당 기기에 대한 공격을 의심하도록 한다. 그러므로 우리의 제안 기법은 cipher suite rollback 공격 탐지를 향상시키고 안전한 메시지 통신을 한다.

Purpose: This study aimed to identify the factors influencing positive subjective health awareness of middle school-age multicultural adolescents in Korea. Methods: This study used data from the fourth to sixth waves of the Multicultural Adolescents Panel Study conducted by the National Youth Policy Institute. In this study, a panel logit model analysis was performed using the Eviews 8.0 program (p<.050). Results: Socioeconomic status (r=.02, t=2.13, p=.033), body satisfaction (r=.71, t=1.97, p=.048), and depression (r=-.74, t=2.35, p=.018) influenced positive subjective health awareness in multicultural adolescents. When multicultural characteristics were entered into a statistical model with environmental and personal characteristics, multicultural characteristics did not have a significant influence on positive subjective health awareness. Conclusion: Environmental, personal, and multicultural characteristics were related to positive subjective health awareness in multicultural adolescents; thus, an integrated approach considering those variables is recommended. Nursing interventions and educational programs are needed to improve the psychological status of multicultural adolescents and reduce prejudice about them. In addition, nurses need to be sensitive to multicultural characteristics and the developmental characteristics of multicultural adolescents.

This study was undertaken to evaluate the effects of β-mercaptoethanol on lipid peroxidation and fertilization ability in vitro by xanthine (X)-xanthine oxidase (XO) system in boar spermatozoa frozen-thawed. When spermatozoa were inseminated in medium with X and/or XO, the penetration rates in all conditions were higher in medium with that than without β-mercaptoethanol. However, significant differences were not observed between medium with and without β-mercaptoethanol. The lipid peroxidation of sperm was evaluated on the basis of malondialdehyde (MDA) production.

The availability of endoscope has been increased not only for observing inner parts of body but also for operating. Nowdays, the market of the endoscope has been widely extended and we presume that the value of marketablity will reach to wide. Most of the endoscope equipment is very expensive and as well, it costs a lot to repair or change the specific parts of equipment when it´s out of order on account of carelessness. About 90 percent of the endoscope equipment in the world is made in Japan. Therefore, to buy or repair the equipment, we can´t help outflowing foreign currency. In domestic, the efforts for localization and manufacturing the endoscope equipment are short. This paper shows that captured image from a CCD miniature carema is managed ...

Many people who wear skinny jeans have expressed satisfaction or concern regarding the side effects of wearing the garments, based on specific demographic characteristics. For this study, we disseminated 373 copies of a questionnaire. Study subjects were eighteen-to fifty-nine-year-old man and women Linear regression was used for data analysis. Descriptive statistics included the ${\chi}^2$ test, t-test, ANOVA and Duncan multiple range test. Corresponding results in terms of difference analysis overall were significant when based on gender, marital status, age, occupation and the average score of satisfaction. The values were approximately three points. The qualitative results of difference analysis for side effects in wearing skinny jeans according to demographic characteristics were identified as the experience of displeasure by pressure. There was a significant difference according to gender. Leg edema was also observed based on gender, marital status, age, occupation and the experience of poor circulation of blood. The factor that has the greatest influence on satisfaction on wearing skinny jeans was sitting long hours.

For gold balsam, the suitable sulfur balsam which is made of lavender oil and sulfur is found to be the distillate with the content of 15~19% sulfur. The sulfur balsam is distillated under 20mmHg vaccum at 84~105$^{\circ}C$. The composition of the compound which is produced by reaction between sulfur balsam and gold chloride is recognized as C10H18SAuCl3. This varys to C10H18SAuCl in water. The reaction constants K from C10H18SAuCl3 to C10H18SAuCl at 30, 40, 5$0^{\circ}C$ are as followsr. K1=7.97~9.28$\times$10-2 K2=2.81~3.79$\times$10-1 K3=4.74~6.74$\times$10-1 The plots of T versus log K are linear, which shows pseudo-first order reaction. The lower temperature is, the more stable C10H18SAuCl3 is. The gold balsam with excess sulfur balsam is increased in stability.

An attempt was made to investigate the chemical compositions of the three plant types such as runner type(Yeoju landrace), semi-Spanish type(Suweon 15ho) and Spanish type(Wasedairu) of peanut. The proximate compositions were lipid 44.25~46.48% and protein 22.54~25.42% in various plant types of peanut, respectively. And the contents of purified free and bond lipids were 43.71~45.44% and 1.74~3.12%, respectively. The predominant fatty acids were oleic, linoleic, palmitic and arachidic acid in the free lipid, and linoleic, oleic and palmitic acid in t도 bond lipid. Pattern of 16 amino acid compositions in three plant types of peanut was shown to be similarity. Major amino acid were glutamic acid(75.30~104.66mg/g), arginine(57.30~74.27mg/g), aspartic acid(41.44~63.05mg/g) and leucine(30.80~39.00mg/g). The richest mineral contained in three plant types of peanut was noticed to be K and followed by Mg, Ca and Na. The lead content was below the authorized tolerance limits.

최근 사물 인터넷(IoT)의 발전으로 계산 집약적이거나 지연시간에 민감한 태스크가 증가하면서, 모바일 엣지 컴퓨팅 기술이 주목받고 있지만 지상에 고정되어 있는 MEC 서버는 사용자의 요구사항 변화에 따라 서버의 위치를 변경하거나 유연하게 대처할 수 없다. 이 문제를 해결하기 위해 UAV(Unmanned Aerial Vehicle)를 추가로 이용해 엣지 서비스를 제공하는 기법이 연구되고 있다. 그러나 UAV는 지상 MEC와는 달리 배터리 용량이 제한되어 있어 태스크 마이그레이션을 통해 에너지 사용량을 최소화하는 것이 필요하다. 본 논문에서는 MEC 서버들 사이의 로드 밸런싱과 UAV MEC 서버의 에너지 효율성을 최적화하기 위해 강화학습 기법인 Q-learning을 이용한 태스크 마이그레이션 기법을 제안한다. 제안 시스템의 성능을 평가하기 위해 UAV의 개수에 따라 실험을 진행하여 잔여 에너지와 로드 밸런싱 측면에서 성능을 분석한다.

본 시험은 산양유 생산을 위해 유기사료를 이용하여 유산양의 적정 에너지 및 단백질 공급 수준과 조농비율을 결정하기 위하여 비유중기 Saanen종 유산양 4두($57.5{\pm}10.8\;kg$ BW)를 이용하여 $4{\times}4$ 라틴방각법으로 실시하였다. 대사에너지 공급수준과 단백질 공급수준을 10.59 (T1), 10.14 (T2), 9.45 (T3) 및 8.75 (T4) MJ/kg과 11.90 (T1), 12.73 (T2), 15.19 (T3) 및 16.60% (T4)로 달리하였으며, 조농비율은 49:51 (T1), 59:41 (T2), 74:26 (T3) 및 90:10 (T4)의 네 처리구로 나누었다. 사료 섭취량 및 체중은 모든 처리구 사이의 유의한 차이가 없었다. 유량은 T3구에서 가장 높았으며, T2 및 T4구와 비교하여 유의하게 높게 나타났다 (p<0.05). 유지방함량과 생산량은 T4구에서 다른 처리구와 비교하여 가장 낮았다 (p<0.05). 유단백질과 유당 생산량은 T1 (61.29 및 70.95 g/일)과 T3 (60.52 및 75.82 g/일)구에서 T2 (50.49 및 59.64 g/일)와 T4 (52.49 및 59.82 g/일)구와 비교하여 유의하게 높게 나타났다. 결과적으로 유산양의 유생산성을 극대화시키기 위해서 에너지 공급수준은 최소 9 MJ/kg 이상과 단백질 공급수준은 최소 15% 이상을 공급해 주어야할 것으로 기대된다.
