In this paper, the artificial intelligence (AI) technology used in the medical image analysis field was analyzed through a literature review. Literature searches were conducted on PubMed, ResearchGate, Google and Cochrane Review using the key word. Through literature search, 114 abstracts were searched, and 98 abstracts were reviewed, excluding 16 duplicates. In the reviewed literature, AI is applied in classification, localization, disease detection, disease segmentation, and fit degree of registration images. In machine learning (ML), prior feature extraction and inputting the extracted feature values into the neural network have disappeared. Instead, it appears that the neural network is changing to a deep learning (DL) method with multiple hidden layers. The reason is thought to be that feature extraction is processed in the DL process due to the increase in the amount of memory of the computer, the improvement of the calculation speed, and the construction of big data. In order to apply the analysis of medical images using AI to medical care, the role of physicians is important. Physicians must be able to interpret and analyze the predictions of AI algorithms. Additional medical education and professional development for existing physicians is needed to understand AI. Also, it seems that a revised curriculum for learners in medical school is needed.

Purpose: This paper is to study the methodology of the development stage of the submarine vessel through the QMST/QCG system. Methods: In order to study the methodology for supporting the development stage of the submarine vessel system, the mission and role for QMST were defined, and the timing and detailed plans of the QCG review were established. Results: Through the analysis of the development stage of the ship's weapon system, QMST was formed, and roles were divided for each subdivision, and methods to effectively support the DAPA IPT were specified. In addition, QCG review timing and plans for submarine safety control lists were established. Conclusion: It is expected that the methodology in the development stage discussed in this study will be useful as a reference when supporting the general weapon system development stage in addition to similar equipment.

Many changes lie ahead for Korea both domestically and internationally including opening of Busan New Port, more active Gwangyang Port as well as rapid growth of Shanghai Port and enhanced services and productivity at Shenzen Port. Compared to newer ports, Busan Port possesses old equipment and facilities. Therefore, in order for Busan Port to maintain its service level and remain competitive and productive, it needs to undergo remodeling to enhance productivity. Such remodeling activities should be implemented on a continual basis by developing and applying new technologies such as those for gate system, berth system, yard system, and IT system Therefore, this study is conducted the introduction. of remodeling concept, the status of Busan Port, and the technical review of remodeling.

Purpose: The cosmetics industry is dynamic and constantly evolving. The hair and beauty field is characterized by being very sensitive to social trends. Therefore, it is necessary to understand the intellectual structure of the social function of hair beauty and to analyze the research and industrial trends related to the beauty field. This study is a literature review and presents specific and practical development plans and growth strategies for the hair care market. Research design, data, and methodology: This review study was conducted by searching PubMed, Google Scholar, Riss, Scopus, and Research Gate. We prepared this by referring to keywords such as the beauty care industry, sustainable development, hair care, hair cosmetics, and hair care market. A total of 468 papers were searched, of which 60 were finally included in this study on the PRISMA flowchart. Results: For good consumption and continuous development of hair cosmetics, it will be necessary to clearly understand the beauty and cosmetic needs of various generations. Conclusions: As income level improvement and quality of life become more important, Korea's beauty industry is attracting a lot of attention as a growth industry that transcends gender and age amid social and cultural development, and its importance is expected to grow in the future.

Despite a growing number of natural language processing shared-tasks dedicated to the use of Twitter data, there is currently no ad-hoc annotation tool for the purpose. During the 6th edition of Biomedical Linked Annotation Hackathon (BLAH), after a short review of 19 generic annotation tools, we adapted GATE and TextAE for annotating Twitter timelines. Although none of the tools reviewed allow the annotation of all information inherent of Twitter timelines, a few may be suitable provided the willingness by annotators to compromise on some functionality.

We have been aware fer some time. that it is becoming harder to develop ASIC only, using the vendor wire model for the current top-down/bottom-up process. Because VDSM has a much bigger wired delay than cell delay, it is also difficult to reduce development time, as well as time-to-market, while developing several million gate ASIC's. The same is true for high frequency ASIC's with VDSM (which have larger wire delay versus cell delay). Therefore, a solution called “RTS-GDS”, using physical constraints fur SOC with timing met, is being actively discussed. This paper suggests a methodology for SOC development by utilizing a top down flow via CWLM along with discussing potential problems. This paper also provides a design flow, including physical synthesis, DFT, floor plan and CWLM, all of which are relevant to proper SOC development.

At Rutherford Appleton Laboratory(RAL), a high-repetition rate ps exicmer laser-plasma x-ray source has been developed for x-ray lithography with a calibrated output of up to 1 watt X-ray average power at 1nm wavelength. In a previous reports this compact x-ray source was used to print 0.18$\mu$m lines for a gate on Si-FET devices and deep three-dimensional structure with 100$\mu$m length, 25$\mu$m width, and 48 $\mu$m depth for a nanotechnology. The deep X-ray lithography is called as LIGA thchnology and getting a wide interest as a new technology for a nano-device. In this report all this works are summarized.

Interpretation of pain by the patients and the observers as well as the methods of treatment remain as varied as are the concepts of pain. The physiologic mechanism of pain is undergoing a serious revision. It is nociceptive receptive mechanism and Melzak concept of gate theory of pain transmission and etc. Therefore pain depend on the evaluator's learning, experience, or specialty.

Neurodegenerative diseases (NDs) often involve the formation of abnormal and toxic protein aggregates, which are thought to be the primary factor in ND occurrence and progression. Aged neurons exhibit marked increases in aggregated protein levels, which can lead to increased cell death in specific brain regions. As no specific drugs/therapies for treating the symptoms or/and progression of NDs are available, obtaining a complete understanding of the mechanism underlying the formation of protein aggregates is needed for designing a novel and efficient removal strategy. Intracellular proteolysis generally involves either the lysosomal or ubiquitin-proteasome system. In this review, we focus on the structure and assembly of the proteasome, proteasome-mediated protein degradation, and the multiple dynamic regulatory mechanisms governing proteasome activity. We also discuss the plausibility of the correlation between changes in proteasome activity and the occurrence of NDs.

국내 애니메이터들에게 희망을 불어넣어줄 낭보가 잇따라 터지고 있다. ‘오세암’이 세계적인 권위의 국제페스티벌에서 영예의 그랑프리를 수상했고, 국내 단편 애니메이션들의 잇달은 수상 소식도 쏟아지고 있다. 정민영 감독의 단편 애니메이션‘길’도 이러한 국내 애니메이션 업계에 빛을 전해주고 있는 작품중 하나. '길'은 지난 4월 30일(한국시각) 폐막한 제47회 샌프란시스코 국제영화제(San Francisco International Film Festival)에서 금문상(GOLDEN GATE AWARDS)을 수상했고, 지난 5월 6일부터 9일까지 4일간 열린 2004년 부산아시아단편영화제에서 교보상을 수상했다. 러닝타임 14분 45초인‘길’은 일반적인 모션 애니메이션이 아닌 편안한 질감의 인형으로 표현된 클레이 애니메이션으로 독창성이 뛰어나고 탄력적 상상력을 지녔다고 평가된다. 정해진 인생길에 순응해가며 살 수밖에 없는 나약한 인간의 모습을 보여준‘길’을 만나본다.
