2020년 7월 전후로 주택가격이 가파르게 상승하던 무렵, 주요 언론을 중심으로 20·30세대가 ‘영끌’하여 주택을 구입하고 있다는 담론이 확산했다. 본 연구는 영끌 담론의 전개 과정을 살펴보고 객관적 분석을 통해 관련 쟁점을 검증하는 것이 목적이다. 통계청의 가계금융복지조사를 토대로 영끌 행위를 조작적으로 정의하고, 자금조달계획서 원자료를 통해 영끌 매수자 규모를 분석했다. 분석 결과, 2020년 상반기부터 2022년 상반기까지 서울 소재 3억원 이상 본인입주용 주택을 구입한 20·30대 영끌 매수자 규모는 debt service ratio 40% 기준으로 설정했을 때 20·30대 영끌 매수자 비중은 3.8%~6.9% 수준인 것으로 추정된다. 오히려 20·30대 내에 영끌 매수자보다는 충분한 자기자금을 갖추고 본인입주용 주택을 구입했거나, 원가족으로부터 비과세 범위를 초과하는 지원금을 받은 매수자가 더 많다. 이에 비추었을 때, 20·30대 전반을 영끌하는 세대로 묘사한 많은 언론보도는 객관성이 결여된 것으로 판단된다. 향후 자금조달계획서를 토대로 주택구입 행위에 대한 실태조사를 별도로 기획하거나, 기존 조사의 행정자료 연계항목을 확대하여 신뢰도를 제고할 필요가 있다. Since July 2020, when housing prices skyrocketed, major media had spread out an issue that the 20·30 generations threw their hearts and souls and put all their cash reserves to buy a house. This study was set to investigate developing processes of the issue and objectively analyze them in order to inspect relevant points. This study also defined the issue, which is called the soulscraping (Yeongkkeul) hereafter, on the basis of the Survey of Household Finances and Living Conditions and the volume of the homebuyers through housing financing plans. The results showed that the portion of people in their 20s and 30s who bought houses over KRW 300,000,000 in Seoul from the 1st half of 2020 to the 1st half of 2022 extended from 3.8% to 6.9% under the standard of debt service ratio 40%. Among them, homebuyers who sustained self-sufficient fund or received money over the non-taxable range from their family to buy their house were much more than those who threw their hearts and souls and put all their cash reserves. As a result, many news from major media that most of the 20·30 generations are bound up with soul-scrapping (Yeongkkeul) seemed to lack objectivity. A survey for housing purchase on the basis of housing financing plans was expected to expand relevant items for administrative information enhance reliability.
누낭염의 병력이 없던 소아에서 발생한 협부농양이 합병된 비루관낭종의 내시경하 조대술 1예

A nasolacrimal duct cyst is an uncommon condition usually treated by ophthalomologists. When there is proximal one-way obstruction at the level of the valve of Rosenmüller or distal obstruction at the level of Hasner’s valve, a cystic swelling at the medial canthus or a nasal cyst develops. This occurs because the nasolacrimal duct is surrounded by a bone and it is natural for the expanding cyst to decompress through the soft tissue nasally or at the medial canthus. A triad of 1) cystic medial canthal mass;2) nasolacrimal duct dilatation;and 3) a contiguous nasal cavity mass is diagnostic of nasolacrimal duct cyst on computed tomogram scans. We experienced a case in which the cheek cellulitis as well as the maxillary and ethmoid sinusitis were developed from an infected nasolacrimal duct cyst. This case was developed during the childhood of the patient, who had no history of dacryocystitis or dacryocele. Computed tomogram showed typical findings of the infected nasolacrimal duct cyst expanding to the cheek. After endoscopic marsupialization of the nasolacrimal duct cyst, symptoms and signs of the infected cyst and sinusitis were rapidly resolved. Thus, we report this case with a review of the literature.

본 논문에서는 데이터마이닝에서 분류·예측 모형의 성과를 높이기 위하여 기존의 변수들의 상호작용효과를 고려한 새로운 변수를 추가는 방법에 대하여 기술한다. 이를 위하여 연관분석을 통하여 종속변수의 값을 성공으로 만드는 데에 유사한 행위를 하는 변수들을 골라내고, 그 변수들의 값을 곱으로 하는 새로운 변수를 추가하여 모형을 구축해 보았다. 주식시장의 이상매매데이터에 적용한 결과, 새로운 모형은 기존의 모형과 비교하여 나은 성과를 나타내었다.
Nasopharyngeal Cancer with Temporomandibular Disorder and Neurologic Symptom: A Case Report
홍정훈,권정승,안형준,김성택,최종훈 대한안면통증∙구강내과학회 2014 Journal of Oral Medicine and Pain Vol.39 No.1
Nasopharyngeal cancer is malignant tumor of nasopharyngeal area that is characterized of lymphadenopathy, pain, otitis media, hearing loss and cranial nerve palsy and may present symptoms similar to temporomandibular disorder such as facial pain and trismus. In this case, the patient with symptoms similar to temporomandibular disorder after surgery for otitis media presented with facial paresthesia and masticatory muscle weakness. Examinaion of trigemimal nerve was shown sensory and motor abnormaility. The patient was referred to a neurologist. Nasopharyngeal cancer was suspected on computed tomography and magnetic resonance imaging and was confirmed by biopsy. If the patient presenting with paresthesia and muscle weakness the cranial nerve examination should be performed regardless of typical temporomandibular disorder symptom. The neurologic symptom can be caused by neoplasm such as brain tumor and nasopharyngeal cancer. Nasopharyngeal cancer on rosenmuller fossa can develop otitis media. Therefore, the patient with otitis media history should be consulted to otorhinolaryngologist to examin the nasopharyngeal area.
