김인아,김민아,Michel van de Velden,이혜성 한국식품과학회 2013 Food Science and Biotechnology Vol.22 No.1

Appropriate psychological positioning of products is important for marketing of foods and beverages. For better product positioning, understanding of how products’extrinsic and intrinsic properties are perceived by consumers is required. In this study, it was explored a refined one-to-one interview technique, check-all-that-apply (CATA) linked with a repertory grid method (RGM) (CATA/RGM) designed to measure consumer-relevant Kansei - psychological feelings and impressions for products - as applied to 12 commercial bottled tea products. For statistical analyses, 2 multivariate statistical methods for Kansei profiling were compared:CATA/RGM based-structured free choice profiling (FCP) and cued elicitation. Results showed that the CATA/RGM efficiently differentiated between products, and the product differentiation obtained from the 2 Kansei profiling techniques corresponded. These results indicated that the consumers in this study have similar Kansei towards bottled teas, and the cued elicitation method, which employed correspondence analysis (CA), was useful for studying the interactions between consumer-relevant Kansei and product properties for a specific target group of consumers.

가톨릭의대 방사선치료실에서는 1987년 2월부터 1990년 7월까지 41개월 동안에 뇌동정맥성 기형으로 확진된 17예에 대해서 6MV선형가속기를 사용하여 SAD법으로 외부방사선 치료를 시행하였다. 치료방법은 총 14예중 4예 $(24\%)$에 대해서는 보통분할방식으로, 13예 $(70\%)$는 정위다방향 고선량 단일 조사로 치료하였다. 이들의 임상적 및 방사선학적 추적검사를 분석하여 다음과 같은 결과를 얻었다. 1. 연령분포는 $10\sim51$세 (중앙값 26세)였고, 남녀 비는 14 : 3으로 나타났다. 2.주증상은 두통이 12예$(70.1\%)$, 경련 5예$(29.4\%)$, 편부전마비 4예$(23.5\%)$ 등의 순이었고, 파열에 따른 출혈을 동반한 경우가 5예 $(29.4\%)$있었다. 3. 각 뇌동정맥성 기형은 중뇌동맥 분지에서 기원한 경우가 7예$(41.2\%)$, 전뇌동맥 3예$(17.6\%)$, 후뇌동맥 2예 $(11.8\%)$, 전뇌 및 후동맥 1예 $(5.9\%)$순으로 나타났다. 4. 보통 분할방식 치료군의 조사량은 $3,020\sim4,500\;cGy/3\sim4$주, 정위다방향 단일고선량 치료는 $1,200\sim3,000$ cGy를 조사하였다. 5. 추적조사기간은 보통분할방식 치료군이 $4\sim43$개월 (중앙값 33개월), 정위 다방향 단일고선량 치료군이 $3\sim21$개월(중앙값 13개월)이었다. 6. 보통분할방식 치료군중 방사선학 추적검사를 실시한 2예에서는 경미한 반응을 보였고, 임상적 추적만을 실시한 2예 중 1예에서는 임상중상의 호전을 보였다. 7. 정위다방향 고선량 단일치료군은 13명 전예에서 방사선학적 추적 검사상 완전반응 2예 $(15.4\%)$, 부분반응 5예 $(38.5\%)$, 경미반응 2예 $(15.4\%)$, 무반응 4예 $(30.7\%)$로 각각 나타났으며, 임상증상의 호전을 보였다. From February 1987 through July 1990, the seventeen cases of inoperable intracranial arteriovenous malformation (AVM) were treated using 6 MV linear accelerator at the Division of Therapautic Radiology, Kang Nam 51. Mary's Hospital. Of seventeen cases, fourteen were male and three were female. Ages ranged from 10 to 51 years (median age of 25 years). The main symtoms were headache, epilepsy and hemiparesis in decreasing order of frequency. The middle cerebral artery is the most common origin of the feeding vessel $(41.2\%)$. Four were treated by conventionally fractionated radiation therapy (CRT, thirteen were treated by stereotactic radiosurgery (RS). duration or follow-up in CRT and RS group were 4 to 43 months (median 33 months) and 3 to 12 months (median 13 months), respectively. When the response was assessed by radiologic follow-up study, two of four CRT group showed minimal response. Of thirteen cases of RS group, two $(15.4\%)$ showed complete response, five $(38\%)$ partial response, two $(15.4\%)$ minimal response and four $(30.7\%)$ no response by the same assessment. There was no statistical significance in terms of follow-up period (p=0.22), size of lesion (p=0.82) and treated dose (p=0.05). Further accumulation of experience is recommended with proper case selection and sufficient follow-up period.

맵리듀스 기반 대량 RDF 데이터셋 압축 변환 및 저장 방법

김인아,이경하,이규철 한국정보통신학회 2022 한국정보통신학회논문지 Vol.26 No.4

With the recent demand for analysis using data, the size of the knowledge graph, which is the data to be analyzed, gradually increased, reaching about 82 billion edges when extracted from the web as a knowledge graph. A lot of knowledge graphs are represented in the form of Resource Description Framework (RDF), which is a standard of W3C for representing metadata for web resources. Because of the characteristics of RDF, existing RDF storages have the limitations of processing time overhead when converting and storing large amounts of RDF data. To resolve these limitations, in this paper, we propose a method of compressing and converting large amounts of RDF data into integer IDs using MapReduce, and vertically partitioning and storing them. Our proposed method demonstrated a high performance improvement of up to 25.2 times compared to RDF-3X and up to 3.7 times compared to H2RDF+. 최근 데이터를 활용한 분석에 대한 수요와 함께 분석 데이터인 지식 그래프의 크기는 점차 증가하여, 웹에서 수집한 데이터를 지식 그래프로 추출하였을 때 약 820억개의 엣지(Edge)를 가지는 수준까지 도달하였다. 많은 지식 그래프들은 웹 자원에 대한 메타데이터를 표현하기 위한 W3C 표준인 RDF(Resource Description Framework) 형식으로 표현되며, RDF 특성으로 인해 기존의 RDF 저장소들은 대량 RDF 데이터를 압축하고 저장할 때 처리 시간의 오버헤드가 발생하는 문제점을 가진다. 본 논문은 이러한 문제점을 개선하기 위해, 맵리듀스를 사용하여 대량 RDF 데이터를 정수 ID로 압축 변환하고, 수직 분할하여 저장하는 방법을 제안한다. 본 논문에서 제안한 방법은 RDF-3X와 비교하였을 때 최대 25.2배, H2RDF+와 비교하였을 때 최대 3.7배까지의 높은 성능 향상을 보였다.

태반조기박리의 3년간 관찰(1984~1986)

김인아 이화여자대학교 의과대학 1988 梨花醫學誌 Vol.- No.20

Abruptio Placentae, 3 years Review(1984∼1986) Abruptio placentae is one of the obstetric hemorrhagic diseases that need emergency treatment and serious cause of maternal death & fetal loss especially in our country having high incidence of toxemia. This data are based on the 36 cases of abruptio placentae among 6618 deliveries at the Department of Obstetrics & Gynecology, Ewha Woman's University Hospital, Seoul during the period 3 years from 1984 to 1986. 1) The incidence of abruptio placentae was 0.54$. 2) The causative predisposing factors of abruptioplacentae were preeclampsia & eclampsia(57.8%), unknown cause(33.3%) and shortness of umbilical cord(15.2). 4) The incidence of abruptio placentae in nulliparous woman was 57.8% and in multiparous woman was 68.6%. 5) The many cases of abruptio placentae occured between 35 and 39 weeks of gestational age. But a half of cases(50.0%) occured before 37 weeks of gestational age, this showed the tendency of preterm delivery. 6) The most common symptom was viginal bleeding (72.2%). Abdominal pain & tenderness was found in 40%. 7) Viginal deliveries were performed in 61.1%, cesarean section in 36.0% and cesarean hystrectomy in 2.8%. 8) the average amount of thransfusion was about 5pints is severe cases and 2pints in mild & moderate cases. 9) The complications of abruptio placentae were followed. Covelaire uterus occured in 17.0%, DIC in 8.3% and postpartum hemorrage in 5.6%. 10) The perinatal motality rate was 25% including stillbirth (16.7%) and neonatal death (8.3%). The three-fourths (75.0%) of cases that had not been undergone prenatal care were resulted in perinatal death. The fetal survival rate admitted within 6 hours after it's onset was 71.4% but significantly decreased in delayed cases.

Measurement of Consumers’ Sensory Discrimination and Preference: Efficiency of Preference-difference Test Utilizing the 3-Point Preference Test Precedes the Same-different Test

김인아,윤지영,이혜성 한국식품과학회 2015 Food Science and Biotechnology Vol.24 No.4

In fast moving consumer goods industries, effective and robust sensory discrimination and preference methods need to achieve various business objectives, such as product reformulation. A new preference-difference test was designed in this study as more effective and reliable method. In this method, 3-point paired-preference test was performed before conducting same-different test. The performance of new method was compared with performances of difference-preference test and conventional pairedpreference test. Each of 256 female consumers participated in all three test methods in a counterbalanced order for discriminating two types of strawberry flavored carbonated drinks. McNemar test and Thurstonian modeling/signal detection theory (SDT) were used to compare the effectiveness of same-different tests. SDT analysis and a significance test using the concept of ‘identicality norm’ were applied to compare robustness of preference tests. The results of these analyses indicated that preference-difference test could not only provide better discrimination but also showed more robust preference results.
