Although significant progress has been made in synthesizing visually realistic face images by Generative Adversarial Networks (GANs), there still lacks effective approaches to provide fine-grained control over the generation process for semantic facial attribute editing. In this work, we propose a novel cross channel self-attention based generative adversarial network (CCA-GAN), which weights the importance of multiple channels of features and archives pixel-level feature alignment and conversion, to reduce the impact on irrelevant attributes while editing the target attributes. Evaluation results show that CCA-GAN outperforms state-of-the-art models on the CelebA dataset, reducing Fréchet Inception Distance (FID) and Kernel Inception Distance (KID) by 15~28% and 25~100%, respectively. Furthermore, visualization of generated samples confirms the effect of disentanglement of the proposed model.

Background Negative-pressure wound therapy (NPWT) is believed to accelerate wound healing by altering wound microvascular blood flow. Although many studies using laser Doppler have found that NPWT increases perfusion, recent work using other modalities has demonstrated that perfusion is reduced. The purpose of this study was to investigate the influence of NPWT on tissue oxygenation of the foot, which is the most sensitive region of the body to ischemia. Methods Transcutaneous partial pressure of oxygen ($TcpO_2$) was used to determine perfusion beneath NPWT dressings of 10 healthy feet. The sensor was placed on the tarso-metatarsal area of the foot and the NPWT dressing was placed above the sensor. $TcpO_2$ was measured until it reached a steady plateau state. The readings obtained at the suction-on period were compared with the initial baseline (pre-suction) readings. Results $TcpO_2$ decreased significantly immediately after applying NPWT, but gradually increased over time until reaching a steady plateau state. The decrease in $TcpO_2$ from baseline to the steady state was 2.9 to 13.9 mm Hg (mean, $9.3{\pm}3.6$ mm Hg; $13.5{\pm}5.8%$; P<0.01). All feet reached a plateau within 20 to 65 minutes after suction was applied. Conclusions NPWT significantly decrease tissue oxygenation of the foot by 2.9 to 13.9 mm Hg. NPWT should be used with caution on feet that do not have adequate tissue oxygenation for wound healing.

A simple HPLC method using UV detection was developed and validated for the determination of levodropropizine (LDP) In dog plasma. The sample was prepared for injection using a liquid-liquid extraction method with 1-phenypiperazine as the internal standard. The mobile phase was methanol - diethylamine solution (0.05 M) (20:80, v/v, pH adjusted to 3.0 with $H_3PO_4$) with a detection wavelength of 240 nm. The limit of quantitation (LOQ) of LDP in a biological matrix was determined to be 25.25 ng/mL. The calibration curve was linear across the concentration range of 25.25 to 2020 ng/mL. The intra-day and inter-day precision values (CV%) were within 7% and accuracy (R.E. %) was within 6% of the nominal values for medium (252.5 ng/mL) and high (2020 ng/mL) LDP concentrations. For the LDP concentration at the LOQ, the intra-day and inter-day precision and accuracy were within 20% and 10%, respectively. The average absolute recovery for LDP was 70.28%. This method was successfully used to analyze plasma samples in a steady-state bioavailability study of a newly developed sustained-release LDP tablets (SR) using immediate-release tablets (IR) as the reference. The relative bioavailability of the SR was determined to be $106.3\;{\pm}\;12.8%$ (n=6). The $C_{max}$ of the SR was significantly lower (p<0.05), and the $t_{max}$ was significantly longer than that of the IR (p<0.05). The results of ANOVA and two one-sided tests indicated that the SR exhibited acceptable sustained release properties and was bioequivalent to the IR.

Purpose: Most of the patients who underwent surgery feels variable kinds of fear or anxiety; an uncomfortable mood state that happens without specific object affects patient's satisfaction before and after the surgery. As music therapy is rather noninvasive method generally used in reducing patient's anxiety, the authors researched about the extent of anxiety with the change of vital sign before the operation while comparing with the cases of patients who took the music therapy at closed reduction under general anesthesia. Method: We divided the patients in 4 groups; A with the premedication (Midazolam, Dormicum$^{(R)}$) before the operation, B with the premedication and music therapy, C with only music therapy, D with no premedication or therapy. And we measured the vital signs after the arrival at the operation room, after induction and 20 minutes after the operation. Also we observed the changes of anxiety index with the STAI (State Trait Anxiety Inventory)-K (Korea)YZ 1 hour before and 8 hours after the surgery. Result: The group B showed the least changes in blood pressure as the group D showed the highest change. Both group C and A showed increase in blood pressure but the upswing in group A was lower than group C. At the change of pulse rate group B showed the lowest upswing also group D showing the highest. Group B showed quite a few upswing but lower than group D, but, at the same time, group A showed lower upswing when comparing two cases. After analysis of STAI-KYZ score, the anxiety relatively decreased in group B and C in comparison with group D. And the index of anxiety state of group A showed just as much to group D. Conclusion: The music therapy is better healthcare method compared to other therapies in reducing anxiety also with satisfying effect who underwent operation. The authors recommend music therapy assisted with use of premedication for better relief of anxiety.

공공기록물 관리에 관한 법률에 따른 기록물관리전문요원의 배치가 이루어지면서 기록물관리는 어느 정도 자리를 잡아가고 있으며, 법률에 따른 기록물관리를 이루기 위해 많은 노력을 기울이고 있다. 기록물관리는 기록물의 생산 분류 정리 이관 수집 평가 폐기 보존 공개 활용 및 이에 부수되는 제반업무를 말한다. 이중에서도 기록물 이관은 해당 기록물이 처리과에서 기록관으로 관리주체가 변경되는 최초 단계를 수행하는 중요한 업무라고 할 수 있다. 이에 따라 본 연구에서는 부산지역 16개 기초자치단체의 이관현황을 살펴보고, 기관의 기록물관리전문요원들의 인터뷰를 통해 이관진행과정에서 발생하는 문제점을 살펴보고 비전자기록물 이관업무 개선방안을 제시하였다.

The annals of Joseon Dynasty designated as a national treasure No. 151 and a UNESCO World Memory are among the greatest archives that should be preserved permanently and inherited to future generations through the proven scientific conservation method. The annals of Joseon Dynasty in the custody of the National Archives of Korea as the sole original archive, has been restricted from the direct physical and chemical approaches. In this study, it is to develop a systematic conservation management scheme, based on the conservation state of the annals. Four books from the annals were selected out of 848 books and their moisture contents and optical property profiles were measured through the books. All the defects previously and newly found were pictured in 10~100 magnifications. The wire marks left on the Hanji's of the annals were analyzed. It was found that water damages and paper molds were prevalent in all four annals selected, and it was recommended to conduct more research for the conservation of those damaged areas. It turned out that various qualities of Hanji's were used for the time of publishing the annals because moisture content, optical properties, and wire mark intervals were quite different between papers even within one book.

본 연구는 2013년 12월 "저작권법"에 도입된 공공저작물의 자유이용 규정의 의미와 세부사항을 기록정보서비스 측면에서 분석한 결과 다음과 같은 한계가 있음을 파악하였다. 첫째, 공공저작물 자유이용규정이 적용되는 기관이 매우 제한적이어서 기록관리법 적용기관을 포괄하지 못하고 있다. 둘째, 국가, 지방자치단체, 공공기관이 생산한 업무상저작물 대다수가 미공표기록임에도 불구하고 자유이용 공공저작물이 되기 위해 공표를 요건으로 하는 것은 대상 저작물의 범위를 지나치게 제한하는 것이다. 이러한 문제점을 개선하기 위하여 각급 학교의 업무상저작물을 자유이용 범위에 포함시키고, 공표 요건을 공개요건으로 변경하는 법개정이 필요함을 제안하였다. 또한 향후 기록관리기준표나 현용 및 준현용기록의 메타데이터 표준에 저작권 관리 항목을 추가하여 기록물 등록과 동시에 저작권 정보를 관리할 것을 제안하였다.
