The purpose of this study is to classify TIFF images, PNG images, and JPEG images using deep learning, and to compare the accuracy by verifying the classification performance. The TIFF, PNG, and JPEG images converted from chest X-ray DICOM images were applied to five deep neural network models performed in image recognition and classification to compare classification performance. The data consisted of a total of 4,000 X-ray images, which were converted from DICOM images into 16-bit TIFF images and 8-bit PNG and JPEG images. The learning models are CNN models - VGG16, ResNet50, InceptionV3, DenseNet121, and EfficientNetB0. The accuracy of the five convolutional neural network models of TIFF images is 99.86%, 99.86%, 99.99%, 100%, and 99.89%. The accuracy of PNG images is 99.88%, 100%, 99.97%, 99.87%, and 100%. The accuracy of JPEG images is 100%, 100%, 99.96%, 99.89%, and 100%. Validation of classification performance using test data showed 100% in accuracy, precision, recall and F1 score. Our classification results show that when DICOM images are converted to TIFF, PNG, and JPEG images and learned through preprocessing, the learning works well in all formats. In medical imaging research using deep learning, the classification performance is not affected by converting DICOM images into any format.

‘맞춤형화장품 제도’가 2020년 3월 14일자로 첫 시행되었다. 맞춤형화장품 제도는 화장품 혼합 및 소분 등 다양한 소비자의 기호 반영과 맞춤형화장품 조제 관리사와 같은 전문 일자리 창출효과와 화장품 산업 활성화를 기대할 수 있다. 급변하는 경제성장의 21세기 현대사회는 단순하게 최신 유행 추구보다는 본인의 만족감을 충족시키는 소비트렌드 중심으로 개인별 취향과 특별함을 강조하는 퍼스널 형태의 맞춤형 제품 관심이 점차 확대되어지고 있다. 본 논문에서는 맞춤형화장품에 대하여 맞춤형화장품과 맞춤형화장품조제관리사, 맞춤형화장품의 시장현황에 대하여 알아보고 맞춤형화장품을 적용한 분야의 연구들을 살펴보았다. 아름다움에 대한 관심이 증가함에 따라 현대인들의 삶의 질과 생활수준 향상은 외모관리가 자기표현의 수단으로 외모는 자기 인식과 함께 인간관계에서도 중요한 요소일 것이다(김민정, 2018). 외모에 대한 관심도가 갈수록 높아지면서 소비자들은 전문가에게 지속적인 관리를 받는 것이 일상이 되어가고 있다(김지윤, 전미정, 2020). 소비자들은 자신의 외모관리를 위한 수단으로 화장품을 구매하고 사용하는데 있어서 유행을 따르기보다는 자신에게 맞는 화장품을 선호하며 맞춤형화장품에 대한 인식은 소비자의 피부상태에 맞추어 즉석에서 만드는 화장품으로 인식하고 있다. 본 연구가 미용분야에서 맞춤형화장품이 피부미용관리 프로그램에 다양하게 활용되며 기초를 다지는 데 기여할 수 있기를 기대한다. Customized Cosmetics Systems’ came into effect on 14 March 2020. With the customized cosmetics system, it is possible to reflect consumers’ various preferences to the mixture and subdivision of cosmetic ingredients, to create jobs like customized cosmetics technical managers, and to promote the cosmetics industry. In today’s society with rapid economic growth, more consumers have been interested in customized products reflecting individuals’ tastes and speciality in the consumption trend for self-satisfaction, rather than the pursuit of the latest fashion. This study tried to find customized cosmetics, customized cosmetics technical managers, and the market state of customized cosmetics, and to look into other studies on customized cosmetics. As people pay more attention to beauty along with the improved quality of life and standard of living, their care for looks is the means of self-expression. Therefore, appearance together with self-awareness is a critical factor in human relationship (Kim Min-jeong, 2018). The more consumers are interested in their looks, the more they receive professional care in everyday life (Jeong Mi-jeong, 2020). When buying and using cosmetic products as the means for appearance management, consumers prefer the cosmetics suitable for themselves, rather than follow a fashion and think of customized cosmetics as the cosmetic products made instantly in consideration of their skin conditions. It is expected that this study contributes to applying customized cosmetics much to skin care programs and laying the foundation for them.
태풍 차바(CHABA)로 인한 지방정부와 주민간의 갈등사례의 정책적 함의 : 울산 중구 피해사례를 중심으로

최근 지진, 태풍, 집중호우 등으로 인한 재난피해 규모가 커지면서 재난관리주체인 정부 및 지자체의 대응미흡이 쟁점화 되어 행정기관과 피해주민 간 첨예한 갈등이 발생되고 있는 실정이다. 2016년도에 발생한 태풍 차바 사례 역시 현재까지도 천재와 인재여부를 두고 갈등이 지속되고 있다. 재난의 발생 원인을 둘러싼 이해관계자들 간의 인식차이가 재난갈등으로 이어져 사회적 문제로 이슈화되고 있는 시점에서 재난갈등의 발생원인과 해결방안에 대한 모색은 더욱 요구된다. 재난을 극복하기 위한 지역공동체는 재난관리 역량과 연계되기 때문에 재난갈등으로 지역공동체가 와해될 경우 재난관리역량의 약화로 재난이 확산될 수 있다. 이에 재난갈등에 대한 면밀한 분석과 해결방안의 모색은 매우 중요하다. 본 연구에서는 현재까지도 첨예한 갈등이 지속되고 있는 태풍 차바 사례를 선정하여 재난갈등에 영향을 미치는 원인을 분석하고 해결방안을 제시하고자 한다. 연구결과에 따르면, 재난갈등은 예방, 대비단계에서는 행정적 요인 중 법준수요인이, 대응, 복구단계에서는 행정적 요인 중 법 준수, 상호신뢰, 정보공개 요인이 주요한 갈등요인으로 작용하는 것으로 분석되었다. 이러한 연구결과를 토대로 본 연구에서는 재난갈등 관리방안으로 재난갈등관리 행동조치 매뉴얼 구축 및 교육 강화, 긴급정보공개 제도 도입, 재난법률지원서비스 체계구축 및 운영 등을 제안하고자 한다. With the recent occurrence of large-scale damage from earthquakes, typhoons, and heavy rains, insufficient disaster responses of central and local governments, which are primarily responsible for disaster management, have led to sharp conflicts between administrative authorities and victims from the disaster. The typhoon Chiba case, which has occurred in 2016, is still controversial in determining whether it was natural or man-made disaster. While differences in perceiving the causes of large-scale damage among related parties lead to disaster conflicts to be treated as a social problem, efforts for determining the causes of and solution for the disaster conflicts are needed more than before. Since capability of a local community to overcome natural disaster is closely associated with capacity for disaster management, if a local community is put into disaster conflicts, damage from disaster may even get worse from weakened disaster management capacity. Therefore, it is very important to closely analyze disaster conflicts and to find a solution thereto. In this respect, this research studies the typhoon Chiba case, with which disaster conflicts are still under way, in an attempt to analyze the causes affecting disaster conflict and propose a solution to the conflict. According to the research, in the prevention and preparation phases, law compliance is important among administrative factors of the disaster conflict while law compliance, mutual trust, and information disclosure are important in the response and restoration phases. Based on the research result, we propose development of a manual for managing disaster conflicts, strengthening of education, adoption of an emergency information disclosure system, and establishment and operation of a legal support service system for disaster conflicts as a solution for managing disaster conflicts.

Purpose: We encountered two patients who developed Bacillus cereus endophthalmitis following trauma and eventually underwent enucleation, after aggressive antibiotic therapy. Methods: When removing the intraocular foreign bodies, vancomycin and ceftazidime were injected intravitreally. The patients received postoperative topical fortified antibiotics hourly and underwent intravenous antibiotic therapy. Results: After the operation, rapid corneal melting progressed to impending perforation in one patient’s eye and enucleation was done on postoperative day 11. The eye of another patient progressed to phthisis bulbi and the patient underwent enucleation on postoperative day 45. Conclusions: Bacillus cereus is one of the most aggressive and devastating organisms that causes post-traumatic endophthalmitis and results in poor visual outcome. It is thought to be better to prevent the loss of anatomic integrity and visual function than to perform early intravitreal injection of antibiotics when the operation might be delayed.

Purpose. In this study, we aim to clarify the correlation between happiness, appearance, and happiness index among many happiness factors based on the influence of quality of life on the quality of life and the affect of appearance on the happiness index. Methods. We conducted a self - filling questionnaire survey for college students in Busan from March 30 to May 10, 2017, and analyzed 392 copies of the 412 questionnaires, excluding 20 inappropriate copies. In the questionnaire, categorical data were analyzed by frequency and percentage (%) using the SPSS program (ver. 23.0, Chicago, Illinois, USA) by examining 11 items of general characteristics, successive data are presented as mean standard deviation. Results. The higher the grades, the better the dating. Women(3.32) are more likely than men(2.74) at the appearance interest(p>0.001) and the higher the grades, the better. If it's dating someone else, higher than not to do at the appearance interest and all of the questions showed higher interest in appearance. Also there was a high percentage of thought'My life is ideal in all aspects'If it's dating someone else, higher than not to do (p=0.007) Conclusion. At present, There is a high interest in the appearance of dating. In addition, the happiness index according to the current resentment status was higher in both the single item happiness index and the 5 item happiness index, and was significant in the item "My life is ideal in all aspects". Therefore, it is related to the happiness index as well as the appearance interest. Finally, whether or not dating and appearance interest play a role in raising the happiness of the individual.

이 글은 지방에 거주하는 필리핀 결혼이주 여성과 가족의 구성원들이 어떻게 서로를 맞추어 나가며 하나의 사회단위로서 가족생존전략을 구사하는지 분석한다. 이들 가족은 한국 사회의 빠른 변화 속에서, 부계혈통과 성별분업에 기반한 가족을 유지해야 하는 남편의 필요와, 출생가족의 복리와 자신의 새로운 미래 개척을 위해 결혼이주를 선택한 아내의 동기가 맞아 떨어져서 성립된다. 부부관계는 ‘한국 국민이라는 위치와 경제력’ 대(對) ‘이주를 통한 혼입(婚入)과 가사노동 수행’이 교환되는 암묵적인 계약에 기반한다. 남편이 국민상의 지위를 기반으로 특정한 노동과 감정 서비스를 요구할 수 있다는 점은 이들 부부관계에 특징적인 구조적 불평등이다. 이에 아내는 필리핀 식을 주장하거나 다른 관계를 강화하거나 사랑과 책임감을 내세워 보상체계를 고안해야 할 필요를 느낀다. 한편 부계혈통집단이 존재하지 않는 필리핀에서 온 며느리는 한국 시어머니의 위치를 완전히 받아들이기 힘들다. 이에 시어머니는 다양한 전략을 사용하여 며느리를 포섭해야 하고, 고부관계는 갈등적이 될 수 있다. 필리핀 며느리는 부계 직계가족을 ‘주어진 가족’으로 받아들이지 않고, 자신이 생각하는 가족에 시(부)모나 다른 남편친척들을 포함시키기도 제외하기도 하면서 ‘가족을 만들어’ 가고자 한다. 초청한 친정식구와의 동거로 가족은 양변(兩邊)화될 수도 있지만, 아이들이 커갈수록 주어진 부계직계가족을 받아들여야 할 필요성도 커진다. 이 글에서 주목하는 국제결혼에서 문화적 차이는, 친족제도를 포함하여, 그 자체로 고정된 의미를 가지는 것이 아니며 가족생존전략이나 개인의 행복추구전략에서 동원되는 자원으로서 의미를 가진다. In this article, I attempted to analyze how Filipina migrant wives living in rural areas and their Korean family members interact with one another as part of their efforts to create harmony amongst themselves, and how they devise strategies that allow them to function as a unified family unit. The majority of intermarriages in Korea are the result of Korean husbands’ need to maintain a patrilineal family structure that is based on a sexual division of labor, meeting Filipina wives’ desire to support their natal families and to change their future through migration. Here, relations between husbands and wives are in effect based on an implicit contract in which ‘one’s status as a Korean national and economic opportunities’ interact with a ‘taking up of residence within the husband’s family and the assumption of domestic chores.’ It is the uniqueness of this unequal relationship that makes it possible for Korean husbands, in their superior position as Korean nationals, to demand that their Filipina wives engage in domestic work and provide emotional services. Faced with such circumstances, Filipina wives insist on the implementation of Filipino ways, try to reinforce extra-familial relationships, and ask their husbands to shower them with affection and assume their share of responsibility in exchange for the sacrifice they must make for their husbands’ families. On the other hand, Filipina wives, who have grown up in a culture based on bilateral kinship, can hardly understand or accept the status afforded to mothers-in-law in Korea. To this end, Korean mothers-in-law need to tactfully control their Filipina daughters-in-law lest such efforts lead to conflicts between the two of them. Filipina wives are reluctant to accept ‘given patrilineal families,’ and instead strive to construct ‘their own families’ based on the selection of appropriate members of their husbands’ relatives, including their mothers-in-law. Family boundaries can eventually be transformed into more bilateral ones once Filipino family members are invited to Korea to live with their relatives in exchange for helping out with duties such as child rearing and household chores. Filipina wives, however, also need to strengthen given patrilineal family relations as their children grow up, and require more support and resources from their families. The cultural differences in such marriages, including the kinship system, do not signify something in and of themselves, but rather only take on meaning when utilized as the cultural resources employed as part of strategies designed to achieve family welfare or individual happiness.
가임 여성에서 제왕절개술 동안 Deciduosis의 유병율과 자궁내막증과의 관계
김민정,김현정,송재연,김수연,정재은,조현희,김진홍,김장흡,유영옥,권동진,김미란,임용택,Kim, Min-Joung,Kim, Hyun-Jung,Song, Jae-Yen,Kim, Sue-Yeon,Chung, Jae-Eun,Jo, Hyun-Hee,Kim, Jin-Hong,Kim, Jang-Heub,Lew, Young-Ok,Kwon, Dong-Jin,Kim, Mee 대한생식의학회 2009 Clinical and Experimental Reproductive Medicine Vol.36 No.2
Objective: To investigate the prevalence, the distribution of deciduosis, and the relationship with endometriosis in fertile women during Cesarean delivery. Methods: In this study, pelvic tissues suspicious for ectopic deciduas were taken for biopsy during Cesarean section from 154 parturients of full term pregnancy from January 1990 to December 2003. And then those patients were followed up till April 2008. Results: Tissues from 94 parturients (94/154, 61%) were evaluated histopathologically, and ectopic decidua was observed in 70.2% (66/94). Ectopic sites were ovaries only (65/94, 69.1%), ovaries and uterine serosa (12/94, 12.8%), uterine serosa only (9/94, 9.6%), and pelvic serosa. Twenty seven (27/66, 40.9%) parturients had past history of diagnosis and treatments for endometriosis. We have tried to connect 39 (39/66, 59.1%) patients who had never been diagnosed for endometriosis but pathologically confirmed for deciduosis, and 18 patients were able to contact by phone. Twelve patients (12/18, 66.6%) showed no symptoms of endometriosis and had not received any treatments for endometriosis. Conclusion: We can conclude that most of incidental cases confirmed pathologically for deciduosis during pregnancy do not symptomatically progress. 목 적: 임신 능이 확인된 가임 여성에서 다능성 세포가 화생되거나 이전에 존재하던 골반 내 자궁내막증으로부터 발생하는 deciduosis의 발생빈도와 분포, 자궁내막증과의 관계를 알아보고자 하였다. 연구방법: 1990년 1월부터 2003년 12월까지 만삭임신에 이른 154명에서 제왕절개술시 의심되는 병변에서 조직검사를 시행하여 deciduosis의 빈도를 조사하였다. 결 과: 여러 다른 장기의 ectopic decidua는 94명 (94/154, 61%)에서 조사되었고, 이 중 66명 (66/94, 70.2%)에서 조직 검사상 deciduosis로 진단되었다. 발생빈도는 난소 (65/94, 69.1%), 난소와 자궁장막 (12/94, 12.8%), 자궁장막 (9/94, 9.6%), 복막 (2/94, 2.1%) 순이었다. 이 중 27예 (27/66, 40.9%)는 임신 전에 이미 자궁내막증으로 진단받아 다른 치료를 받았던 경력이 있던 여성이었고, 39예 (39/66, 59.1%)는 임신 전 자궁내막증으로 진단받지 않았던 경우였다. 임신 중에 deciduosis로 조직학적 확진을 받았지만 자궁내막증의 기왕력이 없었던 38명을 대상으로 2008년 4월 전화연락을 시도한 결과 통화 가능했던 18명 중 12명 (66.6%)이 다른 증상이 없어 특별한 치료 없이 지내고 있었다. 결 론: 본 연구에서 임신 시 조직학적으로 deciduosis가 확인된 대부분의 경우 자궁내막증으로의 진행은 없었다.
림프절에 발생한 랑게르한스 세포 조직구증의 세침흡인 세포소견 -1예 보고-

Langerhans cell histiocytosis (LCH) is a pleomorphic disease entity characterized by local or disseminated atypical Langerhans cells (LCs) found most commonly in bone, lungs, mucocutaneous structures and endocrine organs. Among different sites, unifocal disease confined to a lymph node (LN) is rare. We report a case of LCH confined to a LN in a 38-year-old male who presented with a 2 cm-sized cervical mass. The fine needle aspiration (FNA) smears of cervical LN showed high cellularity having isolated LCs with contorted nuclei and nuclear grooves mixed in multinucleated giant cells, small lymphocytes and eosinophils. Charcot-Leyden crystals were also seen, as were a few dendritic-like cells and intranuclear inclusions. Confirmation of LCH was made by histopathologic studies, positive reactions for S-100 protein and CD1a immunohistochemical staining and by the demonstration of Birbeck granules on electron microscopy. The differentials to be considered include dermatopathic lymphadenitis, sinus histiocytosis with massive lymphadenopathy, Hodgkin's lymphoma and malignant histiocytosis. The characteristic cytomorphologic pattern of LCH in a LN FNA smear plays an important role in suggesting the diagnosis of LCH.
