<P><B>Purpose</B></P><P>This study was aimed to investigate the relationship between indoor air pollutant levels and residential environment in children with atopic dermatitis (AD) living in Seoul.</P><P><B>Methods</B></P><P>A total of 150 children with AD were included. Residential environment was assessed by questionnaires which were completed by their parents. To evaluate the level of exposure to the indoor air pollutants, concentrations of the indoor air pollutants including particulate matter with diameter less than 10 µm (PM<SUB>10</SUB>), formaldehyde, carbon dioxide (CO<SUB>2</SUB>), carbon monoxide (CO), nitrogen dioxide (NO<SUB>2</SUB>), Total Volatile Organic Compound (TVOC), benzene, toluene, ethyl-benzene, xylene, styrene, bacterial aerosols, and airborne fungi were measured.</P><P><B>Results</B></P><P>A significant difference was exhibited in the levels of PM<SUB>10</SUB> in case of visible fungus on the walls (<I>P</I>=0.047). There was relationship between the construction year of the house, moving to a newly constructed building within 1 year and formaldehyde level. With the use of artificial air freshener, the differences were found in the concentrations of TVOC (<I>P</I>=0.003), benzene (<I>P</I>=0.015), toluene (<I>P</I>=0.012) and ethyl-benzene (<I>P</I>=0.027). The concentration of xylene was significantly high when oil was used as heating fuel (<I>P</I>=0.015). Styrene exhibited differences depending on building type and its concentrations were significantly high in a residential and commercial complex building (<I>P</I>=0.005). The indoor concentration of bacterial aerosols was significantly low with the use of air cleaner (<I>P</I>=0.045). High NO<SUB>2</SUB>, benzene concentrations were present in case of almost no ventilation (<I>P</I>=0.028 and <I>P</I>=0.028, respectively).</P><P><B>Conclusions</B></P><P>Individual residential environments are closely related with the levels of the indoor air pollutants. To alleviate AD symptoms, simple questions about residential environments such as visible fungus on the walls and the use of artificial air freshener are helpful to assess the possibility of increased indoor air pollutant levels when direct measurement is not available.</P>

Arthroscopic Resection of a Tenosynovial Giant Cell Tumor in the Wrist : A Case Report

Lee, Young-Keun,Han, Youngshin,Lee, Malrey Williams & Wilkins Co 2015 Medicine Vol.94 No.42

<P><B>Abstract</B></P><P>The treatment for giant cell tumors of the tendon sheath is surgical therapy, but surgical recurrence rates were reported to be as high as 50% in some cases. Therefore, complete radical excision of the lesion is the treatment of choice. If the tumor originates from the joint, it is important to perform capsulotomy. Here, the authors report the first case of successful treatment of a localized intra-articular giant cell tumor in the wrist by arthroscopic resection.</P><P>A 28-year-old right-handed woman visited the clinic because of left wrist ulnar-side pain, which had been aggravated during the previous 15 days. Vague ulnar-side wrist pain had begun 2 years ago. When the authors examined the patient, the wrist showed mild swelling on the volo-ulnar aspect and the distal radioulnar joint, as well as volar joint line tenderness. She showed a positive result on the ulnocarpal stress test and displayed limited range of motion. Magnetic resonance imaging revealed an intra-articular mass with synovitis in the ulnocarpal joint. Wrist arthroscopy was performed using standard portals under regional anesthesia. The arthroscopic findings revealed a large, well-encapsulated, yellow lobulated soft-tissue mass that was attached to the volar side of the ulnocarpal ligament and connected to the extra-articular side. The mass was completely excised piece by piece with a grasping forceps. Histopathologic examination revealed that the lesion was an intra-articular localized form of a tenosynovial giant cell tumor.</P><P>At 24-month follow-up, the patient was completely asymptomatic and had full range of motion in her left wrist, and no recurrence was found in magnetic resonance imaging follow-up evaluations.</P><P>The authors suggest that the arthroscopic excision of intra-articular giant cell tumors, as in this case, may be an alternative method to open excisions, with many advantages.</P>

미디어 이용시간 및 부모의 상호작용에 따른 아동의 어휘력 차이 - 군집유형별 분석을 중심으로

이영신 ( Lee Youngshin ),이지현 ( Lee Jihyon ),김지연 ( Kim Jiyeon ) 열린부모교육학회 2018 열린부모교육연구 Vol.10 No.1

본 연구는 미디어 이용시간 및 부모 상호작용과 아동의 어휘력 간의 관련성을 검토하고, 미디어 이용시간과 부모 상호작용의 군집별로 아동의 어휘력의 차이 분석을 목적으로 하였다. 한국아동패널 8차년도(2015) 자료의 아동과 어머니 1,598쌍을 대상으로 하였다. 아동의 미디어 이용의 평균시간, ECLS-K의 부모 상호작용 관련 문항을, 아동의 어휘력은 REVT를 사용하였다. 분석은 t검증, 일원변량분석, 상관분석, 군집분석 및 공변량분석을 실시하였다. 연구결과는 첫째, 아동은 일평균 2.43시간 부모의 상호작용을 경험했으며, 미디어는 일평균 1.86시간 이용하였다. 아동의 미디어 이용시간은 출생순위 및 소득 수준이 낮을수록 높았다. 둘째, 미디어 이용시간이 늘어날수록 아동의 어휘력은 낮았다. 셋째, 미디어 이용시간과 부모의 상호작용의 군집별 아동의 어휘력에 차이가 있었다. 미디어 이용시간이 적고, 부모 상호작용 수준이 높은 아동의 어휘력 점수가 가장 높았다. 또한, 미디어 이용시간이 많은 집단에서는 부모의 상호작용 수준이 높은 집단이 낮은 집단에 비해 이해어휘력 점수가 높았다. 이는 미디어 이용시간이 유사한 경우, 부모의 상호작용 수준에 따라 아동의 어휘력에 차이가 있음을 의미한다. The purpose of this study was to analyze the difference of children's vocabulary ability according to their media use and parent-child interaction. The data were derived from the research statistics on 1,598 mothers with 7-year-old child in 8th Panel Study of Korean Children, by KICCE in 2015. The data were analyzed by t-test, ANOVA, correlation analysis, cluster analysis, and ANCOVA. The results shows that the children experienced 2.43 hours of interaction with their parents and spent 1.86 hours on media per day. Second, the children's vocabulary ability was significantly low as their media usage time increased. Third, the children with low media usage time and the high level of parent-child interaction showed the highest level of vocabulary ability. In addition, when children’s media usage time is similar, their vocabulary scores vary according to their parent-child interaction levels. In conclusion, although children may spend a great deal of time on media, their vocabulary ability might improve to some extent by the high quality interaction with their parents.

타로(Tarot) 콘텐츠 개발에 활용 가능한 소비자 조사 연구 : 20·30대 소비자 중심으로

이영신 ( Youngshin Lee ),윤수인 ( Suin Yoon ) 서경대학교 디자인연구소 2019 디자인 이노베이션 연구 Vol.4 No.0

본 연구는 타로카드를 이용하는 20·30대 소비자층의 데모그래픽스, 사이코그래픽스를 설문조사를 통해 타로 경험자와 비경험자의 특성을 알아보았다. 이론 고찰을 통해 타로카드의 특징과 개념, 소비자 조사 방법을 수집하고 이를 통해 설문지를 설계하였다. 설계한 설문지는 2019년 11월 26일부터 2019년 12월 01일까지 20·30대 남성과 여성, 95명에게 설문 되었다. 조사된 자료는 요인분석을 통해 ‘활동중시형’, ‘관심중시형’, ‘의견중시형’ 세 가지로 분류되었다. 이후 타로 경험자와 비경험자로 집단을 나누고 T-Test를 통해 차이를 분석하였다. 분석결과, ‘의견중시형’이 유의한 것으로 나타났다. 경험자의 성별은 여성이 61.1%로 남성보다 많은 비율을 차지하고 있었고, 반대로 남성의 경우 75.6%가 비경험자의 비율을 차지하고 있었다. 따라서 타로 콘텐츠를 기획할 때 남성보다 여성에 초점을 맞추어 전략을 제시하면 좋을 것이다. 본 연구는 20·30대에 한정된 100개 미만의 표본 수를 조사했다는 아쉬움이 있었다. 현재의 타로 콘텐츠는 디지털 문명을 통해 소비자들이 더 쉽게 접근할 수 있는 환경이다. 따라서 후속연구에서는 결과가 다양한 타로 콘텐츠 개발의 기초자료로 활용되기를 기대하고, 좀 더 풍부한 표본을 기반으로한 연구가 이루어져야 할 것이다. This study examined the characteristics of experienced and non-experienced consumers by surveying the demographics and mental retardation of consumers in their 20s and 30s using tarot cards. Through theoretical consideration, the features, concepts, and methods of consumer research of tarot cards were collected and questionnaires were designed. The designed questionnaire was surveyed by 95 men, women and men in their 20s and 30s from Nov. 26, 2019 to Dec. 1, 2019. An Analysis of the 'Activity of type', 'of type of interest' surveyed data, classified into three 'opinion of type'. Afterwards, the group was divided into tarot and non-experienced people and the difference was analyzed through T-Test. Analysis shows that 'opinion type' is significant. Women accounted for 61.1% of the experienced, compared with 75.6% of the non-experienced in men. Therefore, when planning tarot content, it would be good to present a strategy focusing on women rather than men. It was regrettable that this study examined the number of samples less than 100 limited to those in their 20s and 30s. Current tarot content is an environment that is more accessible to consumers through digital civilization. Therefore, in subsequent studies, we hope that the results will be used as the basis for the development of various tarot content, and more abundant sample-based research will have to be done.
