수면, 기억 그리고 학습의 연관성은 실제 매우 복잡하다. 많은 연구에도 불구하고 명확한 연구결과는 아직 없다. 우리는 이 연구에서 평소와는 달리 시험 전날 수면 변화 양상이 집중력에 어느 정도 영향력을 미치는지 알아보고자 하였고, 이를 이용해 효율적인 수면 관리를 할 수 있는 기초자료로 삼고자 하였다. 동국대 의대 본과 1학년생 중 지원자 30명과 본과 2학년생 10명을 대상으로 평상시 상태와 시험 직후 수면이 부족한 상태에서 각각 K-PES TEST를 실시하여 총 8항목에 걸쳐 암기력, 판단력, 단순반응의 변화정도를 검사하였다. 또 설문조사를 병행하여 결과에 영향을 미칠 수 있는 다른 인자들도 파악하였다. 수면량에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 인간의 최대 생리학적 기능은 꼭 수면부족에 의해 좌우되는 것은 아니다. 그러나, 수면감소는 피로를 증가시키고, 동기부여를 감소시키나 단, 새로운 사실을 학습하는 데에는 큰 영향을 끼치지 않는다. 즉, 수면부족으로 장시간 깨어있는 것은 정확성과 반응성을 떨어뜨린다. 흡연에 대한 부호 숫자 짝짓기(순간 판단력)을 검사한 결과, 니코틴의 수면에 대한 상호관계는 알려지지 않았고, 인간의 감정이나 의식, 인식에 영향을 주는 것으로 알고있지만, 장기적은 측면에서 흡연이나 알코올은 인식능력과 무관한 것 같다. 카페인에 대한 숫자 외우기(암기력)검사 결과, 카페인은 spacial selective attention에는 특별한 영향을 주지 않지만 지각과정이나 주의 집중에 큰 효과를 주며, 인간의 의식 수행에 긍정적인 효과를 준다. 즉 카페인은 활력, 혼란, 피로상태를 변화시키고 visual analog scales에서 휴식상태에 가까운 양상을 나타낸다. 또 48시간 동안 수면을 취하지 않은 사람에게 카페인은 집중력과 장시간의 좋은 기분을 유지하게 하였다. 그러나 규칙적, 비규칙적으로 먹는 사람간에는 인지수행력의 차이를 보이지 않으며 상용자에서는 상당한 내성이 보인다. 수면패턴에 대한 숫자 더하기(순간 판단력)검사 결과, 집중력은 수면패턴에 의해서도 영향을 받고, 수면패턴이 바뀌게 되면 순간판단력을 저하시킨다. This study was performed to evaluate relationship of sleep and attention, and to control sleep effectively. We conducted a K-PES test of 40 medical students. K-PES contains eight elements, for example, simple response, selective response, color pairing, OddEven discrimination, number addition, number-symbol matching, memory, right-tapping, left tapping. Through these, we tested changes of memory, judgement, simple response. And we conducted a questionnaire survey to exclude bias. Results are as follows. As a results of number-symbol matching test, we know that sleeplessness is not complete responsible for physiologic function for humans. But, decreased sleep increases fatigue and decreases motivation, but no influence on learning new materials. So, long term sleeplessness decreases precision and responsibility. As a results of number-symbol matching test on smoking, a relationship of nicotine and sleep is not certain. A point of view in long term period, smoking and drinking is not related cognition, even if we know that those influence mood, consciousness and cognition. As a results of memory work test on caffeine, caffeine does not influence spacial selective attention, but mainly does perception, attention and consiousness process. Namely caffeine changes energetic activities, chaos, fatigue states and shows resting state in visual analog scales In sleeplessness for 48 hours, caffeine produced attention and good mood for a long time. But, in case of cognitive process no significance shows in regular or irregular diet. Regular diet shows high resistance. As a results of number addition test on sleep patterns, seep patterns influence attention, changes of sleep patterns decrease a moment judgement.

Background: Q-switched lasers have made it possible to remove tattoos without leaving unsightly scars. Objective: Tobdetermine the optimal time for permanent makeup removal using Q-switched Nd:YAG and ruby lasers, we compared the degree of removal and associated histological changes following irradiation at different time points. Methods: Using black ink and a permanent makeup machine, we performed 108 separate permanent makeup applications on rat skin. The 1,064-nm Q-switched Nd:YAG laser (QSNDL) and 694-nm Q-switched ruby laser (QSRL) were used to irradiate the permanent makeup on the day of its application and also 3, 5, 7, 14, and 21 days later. We assessed changes in pigmentation over time at each irradiated site using Mexameter^ⓡ measurements and skin biopsies. Results: The Mexameter^ⓡ analysis demonstrated no significant differences in pigment removal among irradiations with QSNDL or QSRL on the day of permanent makeup application or at 3, 5, 7, 14, and 21 days later. Histological analysis demonstrated that permanent makeup pigment migrated from the epidermis to the superficial and mid dermis over time. QSNDL more effectively removed pigment throughout the epidermis and dermis compared to QSRL. Conclusion: For maximum pigment removal efficacy, the melanin index results suggest that laser treatment should be performed on the day permanent makeup is applied. However, from the histological perspective, permanent makeup should be removed approximately 1 week later, at which point the crusts have peeled off and the wound repair process is almost complete. In this study, histological analysis suggested the superiority of treatment with QSNDL to that with QSRL. (Korean J Dermatol 2017;55(10):657∼663)

Polyhexamethylene guanidine phosphate (PHMG-p) has been used as a biocide and was incorporated into humidifier disinfectants because of its potent bactericidal activity. Recent epidemiological and toxicological studies reported that PHMG-p increased the risk of asthma in children. This study aimed to investigate the effects of PHMG-p on asthmatic responses. The BALB/c mice were sensitized by diluting 20 μg ovalbumin (OVA) in 1 mg aluminum hydroxide by intraperitoneal route, and then challenged by Intratracheal injection with OVA (20 μg) and PHMG-p (0.1 or 0.5 μg/ml). The inflammatory cell influx into bronchoalveolar lavage (BAL) fluid, immunoglobulin (Ig) E levels, asthma-related cytokine levels and histological changes in the lung were analyzed. PHMG-p exposure groups significantly increased inflammatory cell counts in BAL fluid, cytokine levels, and IgE levels in the OVA-sensitized mice. In conclusion, these findings suggest that exposure to PHMG-p results in aggravated asthmatic inflammation in mice. Further studies are needed to investigate the mechanisms of PHMG-p on asthma exacerbation.

MEKs/ERKs-mediated FBXO1/E2Fs interaction interference modulates G1/S cell cycle transition and cancer cell proliferation

E2F 1, 2, and 3a, (refer to as E2Fs) are a subfamily of E2F transcription factor family that play essential roles in cell-cycle progression, DNA replication, DNA repair, apoptosis, and differentiation. Although the transcriptional regulation of E2Fs has focused on pocket protein retinoblastoma protein complex, recent studies indicate that post-translational modification and stability regulation of E2Fs play key roles in diverse cellular processes. In this study, we found that FBXO1, a component of S-phase kinase-associated protein 1 (SKP1)-cullin 1-F-box protein (SCF) complex, is an E2Fs binding partner. Furthermore, FBXO1 to E2Fs binding induced K48 ubiquitination and subsequent proteasomal degradation of E2Fs. Binding domain analysis indicated that the Arg (R)/Ile (I) and R/Val (V) motifs, which are located in the dimerization domain of E2Fs, of E2F 1 and 3a and E2F2, respectively, acted as degron motifs (DMs) for FBXO1. Notably, RI/AA or RV/AA mutation in the DMs reduced FBXO1-mediated ubiquitination and prolonged the half-lives of E2Fs. Importantly, the stabilities of E2Fs were affected by phosphorylation of threonine residues located near RI and RV residues of DMs. Phosphorylation prediction database analysis and specific inhibitor analysis revealed that MEK/ERK signaling molecules play key roles in FBXO1/E2Fs’ interaction and modulate E2F protein turnover. Moreover, both elevated E2Fs protein levels by knockdown of FBXO1 and decreased E2Fs protein levels by sh-E2F3a delayed G1/S cell cycle transition, resulting in inhibition of cancer cell proliferation. These results demonstrated that FBXO1-E2Fs axis-mediated precise E2Fs stability regulation plays a key role in cell proliferation via G1/S cell cycle transition.

고온 초전도 (HTS) 발전기는 무게, 크기 및 효율의 장점 때문에 활발히 연구되어왔다. 대규모의 초전도 풍력 발전기는 매우 저속의 고토크 회전 기계이다. 이 기계에서는 높은 전자기력과 토크가 중요한 문제이다. 하나의 축에 직렬로 연결된 2개의 발전기는 고토크의 문제를 극복하기위한 하나의 해결 방안이 될 수 있다. 본 논문에서 저자는 15 MW 급 HTS 발전기를 설계하고 분석했다. 3D 유한 요소법을 사용하여 15 MW HTS 발전기의 자기장 분포 및 토크 성능을 확인하였다. 결과적으로 설계된 발전기는 기존의 발전기보다 적은 토크를 생성한다. 제시된 15 MW 초전도 발전기의 설계방식은 대용량 초전도 풍력 발전기의 제작에 있어 고토크로 인한 문제를 해결하는데 활용될 수 있다. A high-temperature superconducting(HTS) generators have been actively studied because of its advantages of weight, size, and efficiency. A large-scale superconducting wind power generator becomes a very low-speed high-torque rotating machine. In these machines, high electromagnetic force and torque are important issued. Two generators connected in series on one shaft design are one of the solution to overcome the high torque problem. In this paper, the authors design and analyze a 15 MW class HTS generator. The 15 MW HTS generator is confirmed in terms of magnetic field distribution and torque performance using a 3D finite element method. As a result, the designed generators generates less torque than a conventional generator. The designed 15 MW superconducting generator will be effectively utilized in the construction of the large-scale wind power generation system.
