이진희,신기일,Lee, Jin-Hee,Shin, Key-Il 한국통계학회 2007 응용통계연구 Vol.20 No.3

표본조사에서 항목무응답 발생 시 결측대체에 사용되는 일반적인 방법은 결측변수와 관계 있는 보조변수를 이용하는 것이다. 최근 이진희 등 (2006)은 2002년 강원지역의 농가경제 자료를 이용하여 표본조사에서 공간통계를 이용한 결측대체 (missing imputation) 방법을 비교하였으며, 자료들 사이에 지역적 상관이 존재할 때 이를 이용한 결측대체가 효율적임을 보였다. 본 논문에서는 이를 확장한 개념으로, 강원지역의 2000-2002까지의 월별 자료가 공간상관과 시계열상관이 존재함을 확인하고 이 관계를 결측대체에 이용하였다. 또한 공간상관과 시계열상관이 모두 존재할 경우 공간시계열 모형을 이용한 결측 대체 방법이 공간모형을 이용하였을 때에 비해 더 효율적임을 모의실험을 통해 확인하였다. It is a common practice to use the auxiliary variables to impute missing values from item nonresponse in surveys. Sometimes there are few auxiliary variables for missing value imputation, but if spatial and time autocorrelations exist, we should use these correlations for better results. Recently, Lee et al. (2006) showed that spatial autocorrelation could be efficiently used for missing value imputation when spatial autocorrelation existed, using the data from the farm household economy data in Gangwon-do, 2002. In this paper, we present au evaluation of spatial and space-time nonresponse imputation methods when there exist spatial and time autocorrelations using the monthly data during 2000-2002 from the same data previously used by Lee et al. (2006). We show that space-time imputation method is more efficient than the other through the numerical simulations.

이진희,김홍,서수지,Lee, Jin-Hui,Kim, Hong,Seo, Su-Ji 대한영상의학회 2001 대한영상의학회지 Vol.45 No.4

목적:경부와 체부 모두를 침범한 자궁 경부암과 자궁내막암에 있어 각각의 종양 성장 형태를 MRI를 통해 알아보고자 하였다. 대상과 방법:1989년 11월부터 1999년 1월까지 자궁경부암으로 MRI를 시행한 784예 중 체부의 침윤이 있었던 37예와 자궁내막암 환자 47예 중 경부의 침윤이 있었던 9예를 대상으로 하였다.조직학적으로 자궁경부암은 편평세포암이 29예,선암이 6예,선편평세포암이 2예 였고 자궁내막암은 선암이 8예,선편평세포암이 1예였다.1.5T unit (Magnetom Vision,Sie-mens, Germany)와 2.0T unit (Spectro-20000,Goldstar,Korea)를 사용하여 각각 종양의 침윤 형태에 관해 후향적 방법으로 조사하였다.분석 방법은 경부 침윤은 부분적 침윤(Cp)과 전층 침윤(Ct)으로 나누었고 부분적 침윤은 다시 내경만 침윤한 경우(Cp-n)와 외경만 침윤한 경우 (Cp-x),내경과 외경 모두를 침윤한 경우(Cp-b)로 나누었다.체부의 침윤은 내막만 침윤한 경우(U-mu),내막과 근층(U-my),내막-근층-장막(U-se)을 침윤한 경우으로 나누어 이들 종양의 침윤 형태에 대해 각각 비교 분석하였다. 결과:자궁경부암 37예 중 내경에 국한된 3예(Cp-n)에서는 내막만 침윤(U-mu)하였고 내경과 외경 모두를 침범한 3예(Cp-b)중에서 내막을 침윤한 경우가 1예(U-mu),근층까지 침윤한 경우 1예(U-my),외막까지 침윤한 경우가 1예(U-se)였고,경부 전층을 침범한 31예(Ct)중에서는 내막만 침윤한 경우 6예(U-mu),장막까지 침윤한 경우가 25예(U-se)였다.자궁내막암 9예 중 내막만 침범한 경우 3예(U-mu)와 근층까지 침범한 5예(U-my)모두에서 경부의 내경만 침윤했고(Cp-n),외막까지 침범한 1예(U-se)에서는 경부 전층(Ct)을 침윤하였다. 결론:자궁경부암이 체부로 침윤시 원발 종양이 경부 전층을 침범하면서 체부 전층을 침윤하는 경향이 있고,자궁내막암은 원발 종양이 내막과 근층을 침범하면서 경부의 내경만을 침윤하는 경향을 보였다. Purpose: To evaluate the growth pattern depicted by MR imaging and used to differentiate between uterine cervcal and endometrial carcinoma where the mass involves both the uterine corpus and cervix. Materials and Methods: The tumor growth pattern observed on MR images obtained between November 1989 and January in 1999 in 37 of 784 cervical carcinomas and 9 of 47 endometrial carcinomas in which the tumor involved both the uterine corpus and cervix was analysed. The histologic type was squamous (n=29), adenocarcinomatous (n=6) or adenosquamous (n=2) in cervical carcinoma, and carcinomatous (n=8) or adenosquamous (n=1) in endometrial carcinoma. A 1.5-T (Magnetom Vision, Siemens, Germany) and a 2.0-T unit (Spectro-20000, Goldstar, Korea) were used to obtain T1-and T2-weighted axial, T2-weighted sagittal and Gd-enhanced images. Tumor involvement of the uterine cervix was classified as either partial(Cp) or total(Ct), and partial involvement(Cp) was subclassified as Cp-n, Cp-x, or Cp-b according to involvement of the endocervix, exocervix or both. Tumors of the uterine corpus were classified as involving the mucosa(U-mu), myometrium(U-my) or serosa(U-se). Results: In 37 cases of cervical carcinoma, all three involving the endocervix(Cp-n) invaded the endometrium(U-mu), three involving both the endo- and exocervix(Cp-b) invaded the endometrium(U-mu, 1 case), my-ometrium(U-my, 1 case), or serosa(U-se, 1 case), and 31 involving the full-thickness of the uterine cervix(Ct) invaded the endometrium (U-mu, 6 cases) or serosa(U-se, 25 cases). In nine cases of endometrial carcinoma, three involving the endometrium(U-mu) and five involving the myometrium(U-my) invaded the endocervix(Cp-n), and one involving the serosa(U-se) invaded the full-thickness of the uterine cervix(Ct). Conclusion: Cervical carcinoma tended to involve the entire cervix and the full thickness of the uterine corpus, but endometrial carcinoma tended to involve the endometrium or myometrium of the uterine corpus and endocervix.

The purpose of this study was to compare and analyze the sense of value of physical education teachers at secondary schools based on the five educational value orientations classified by Jewett and Bain in 1985. In order to meeting to this purpose this study has accumulated important data of five value orientations which included disciplinary mastery, self actualization, learning process, social reconstrucation and ecologiacl integration using the value orientation inventory developed by Ennis and Hooper in 1988. Five value orientations were compared to determine the difference between respondents' demographic traits: teacher's sex(male/female), teachers' academic degree earned(bachelor's/master's), teachers' school level(junior high/senior high), teachers' type of schools graduated(teacher's college/non-teacher's college), teacher's career(inexperienced/experienced), and teacher's regional groups(Seoul/ Pusan/ Gwangju/Daegu/Daejun). The results were drawn a follows: First, male-teachers responded that they believe the 'disciplinary mastery' as the most important value orientation, but on the other hand 'self-actualization' and 'learning process' meant a lot of to female-teachers. Second, there were significant differences between the teachers in terms of the type of school graduated(bachelor's degree/master's degree). Teachers who earned the bachelor's degree put more importances on the 'disciplinary mastery' and 'social reconstruction' category of the VOI than these who earned bachelor's degree. Third, teachers at senior high school put more emphasis on the 'disciplinary mastery', 'self-actualization' and 'social-reconstruction' of the VOI than these at junior high school. Forth, teachers who graduated non-teacher's college put more emphsis on the 'disciplinary mastery' and 'self-actualization' category of the VOI than these of counterparts. Fifth, experienced teachers believed 'disciplinary mastery' as the most important value orientation, while inexperienced teachers regarded 'learning process' as the most important one. It appeared that the experiencing would influence to the teachers toward a sense of value orientations. Finally, there were no significant differences in the VOI between the teachers' regional groups. On the basis of the results analyzed, several suggestions for the improvement of the curriculum in physical education was made and the conclusion were drawn a follows: First, it is suggested to classify the cultural differences in teacher's education and learning process, which might have caused the results in contradiction to the research work concluded in North America. Due to the differences existing in value orientation in accordance to sexuality of physical education teachers, it is suggested to conduct follow-up researches on the role of sexuality in forming the value orientations of physical education teachers. Secondly it is also required to conduct a further supplementary study on the causes for the contradictory results existing in other researches concluded in Korea. The situational change in education along with methodological aspects in researches can be considered to be the major factors in causing the differeces in results. In particular the adoption of value orientation inventory developed by western could be unfitted to Korean culture, therefore an alternative in research methodology such as Likert Scale or/and in-depth personal interview needs to be adopted. It is also needed to investigate the implication of the educational curriculum of physical education teachers on the formation of teacher's value orientation and their actual behaviors as less distinction between teacher's college and non-teacher's college in noted in this country. Third, there should be a further research to clarify the relationship between value orientation and their actual teaching behavior. The actual teaching behavior of physical education teachers can be attained by analysis of their teaching curriculum, by use of observation system for the behavioral analysis and by analysis of the recognition of teachers' behaviors by their students. The physical education teachers of secondary school as a major objects in the study have tendency to consider the disciplinary mastery to be of the most important. But on the other hand it is not to be neglected that there exists a personal differences in the value orientations of physical education. Lastly a diversity in the research methodology including cross-longitude analysis to further qualify the research on haw value orientations of physical education teachers is formed and changed should be needed while a cross-sectional methodology has been mainly used in the study. Specifically, life-time analysis, in depth-interview and participative observation are considered to be highly appropriate to further researches.

Aflatoxin $B_1$, a known human carcinogen, is the member of aflatoxin subfamily that is most frequently found in contaminated foods. Epidemiological studies have suggested that aflatoxins may be associated with human liver cancer and acute hepatitis. Recently it was reported that the traditional medical herbs sold in domestic markets are contaminated with aflatoxins. Long-term administration of these contaminated medicines could result in adverse health effects. Therefore, it is important to evaluate the levels of exposure to aflatoxin in people who ingest traditional herbal medicines. Blood samples were collected, before and after the herbal medicine intake, from 151 subjects who visited the hospital. The metabolite of aflatoxin $B_1$ in blood, aflatoxin $B_1$-albumin (aflatoxin $B_1$-lysine), is reportedly an appropriate internal exposure indicator, and its levels in the collected bloods were therefore analyzed using a liquid chromatography-mass spectrometry. The analytical method of aflatoxin $B_1$-lysine in blood was firstly optimized in Korea and the levels were detected below quantification limits (2 pg/mg albumin) in this study population. Consequently, the exposure levels of aflatoxin $B_1$ by ingestion of herbal medicines were low but it is important to monitor routinely due to the possibility of risk on the aflatoxin exposure.

언어의 구어성과 문어성에 관한 연구

이진희 한국독어독문학회 2003 獨逸文學 Vol.85 No.-

Mu¨ndlichkeit, gesprochene Sprache, als eingensta¨ndiges Forschungsgebiet hat in der germanistischen Sprachwissenschaft lange Zeit keine besondere Rolle gespielt. Erst mit den technischen Aufzeichnungs- und den verbesserten Abspielmo¨glichkeiten kam die systematische Erforschung in Gang. Zuna¨chst der Strukturen gesprochener Sprache. vor allem in Kontrast zu geschriebenen, dann aber der dialogischen Strukturen. In den letzten Jahren hat das Thema "Mu¨ndlichkeit" versta¨rkte Aufmerksamkeit in einem allgemeineren Rahmen gefunden. Hier geht es um die großen Linien der historischen Entwicklung oraler und literaler Kulturen, um Traditions- und Erza¨hlstrukturen, wie sie etwa in den Arbeiten von Walter J. Ong thematisiert wurden. Ong machte die Bemerkung, dass die modernen elektronischen Medien ein neues Zeitalter der Oralita¨t hervorbra¨chten, und er fu¨gte hinzu, dass diese Oralita¨t "sekunda¨r" sei, weil sie auf Schriftlichkeit gegru¨ndet sei. Eine ganz andere, neue Perspektive in der wissenschaftlichen Diskussion von Mu¨ndlichkeit und Schriftlichkeit ist die Unterscheidung von medialer und konzeptioneller Dimension. Der entscheidende Fortschritt liegt in der Erkenntnis, dass eine direkte, d.h. eindimensionale Abbildung der medialen Dichotomie schriftlich vs. mu¨ndlich auf solche Merkmale (wie hypotaktisch,vs. praktisch, monologisch vs. dialogisch, reflektiert vs. spontan etc.) dem Gegenstand nicht gerecht wird, so, als handele es sich einfach um mit dem Kanal (optisches vs. akustisches Signal) verbundene Unterschiede. Koch/Oesterreicher (1994) verdeutlichen den Ansatz durch die Anordnung verschiedener sprachlicher Vorga¨nge auf einer zweidimensionalen Skala. Ein vertrautes Gespra¨ch ist konzeptionell "mu¨ndlicher" als eine Predigt, ein schriftlicher Tagebucheintrag "weniger achriftlich" (konzeptionell) als ein Leitartikel. Die beiden Dimensionen stehen orthogonal aufeinander, sind als beliebig kombinierbar. Es gibt mu¨ndliche Texte mit hoher konzeptioneller Schriftlichkeit. Schriftlichkeit und Mu¨ndlichketi existieren nicht nebeneinander, sondern durcheinander.

The purpose of this study was to assess the effect of aroma of interior plants on emotional flexibility and the interest of the study. For this purpose, data were gathered from 4 groups of students who exposed to different conditions. A first group of students was a control group. A second group of students was exposed to plants in order to mainly investigate the effect of the sense of sight on emotional flexibility. A third group of students was exposed to plants in order to mainly investigate the effect of the sense of smell on emotional flexibility. A fourth group of students was exposed to both plants and aroma from needle leaf trees in order to investigate the effect of the sense of smell on emotional flexibility. Structured questionnaire that asked responses after their being exposed to the conditions and Likert Scale to assess the response. Students exposed to both plants and aroma from needle leaf trees showed the positive effect of the sense of smell on their emotional flexibility and the interest of the study. Also, the students showed the greatest emotional flexibility and the interest of the study effect compared other groups of students. It suggest that it need to develop plant which feels aroma as well as color of plant when it is brought indoors.

이진희,강명보 한국관광산업학회 2020 Tourism Research Vol.45 No.2

The purpose of this study analyzes structural influences among the quality of the information systems of rural tourism with perceived usefulness, user satisfaction and intention to use. Moreover, a survey was conducted among Korean tourists who had used the application of rural tourism(Rural Experience Application and Gyeongbuk Rural Experience Application) within the last six months based on 311 valid responses. As a result, information quality and interface design quality have a relevant effect on perceived usefulness, by contrast, system quality has a nonsignificant effect. Relationships with information system quality and user satisfaction, system quality and interface design quality have a relevant effect on perceived usefulness. Conversely, information quality has a nonsignificant effect. Perceived usefulness has a significant effect on user satisfaction and intention to use. Use satisfaction has a relevant effect on the intention to use. In the conclusion of comparing rural experience application and the Gyeongbuk rural experience application, all variables except perceived usefulness showed significant differences. System quality, interface design quality, user satisfaction, and intention to use saw an increase in Gyeongbuk rural experience application, while information quality experienced a rise in rural experience application. The results of this study could contribute to success for the information system of rural tourism, and suggestions were made, which based on this. 본 연구의 목적은 농촌체험 앱 품질이 지각된 유용성, 사용자 만족, 사용의도에 미치는 구조적인 영향 관계를 분석하는 것이다. 연구목적 달성을 위하여 설문조사는 최근 6개월 내 농촌체험 앱(농촌체험 앱과 경북농촌체험 앱)을 이용한 경험이 있는 내국인을 대상으로 진행되었으며, 분석은 311부의 유효 표본으로 실시되었다. 분석 결과, 정보품질과 인터페이스 디자인 품질은 지각된 유용성에 유의한 영향을 미쳤지만, 시스템 품질은 유의한 영향을 미치지 않았다. 정보시스템 품질과 사용자 만족 간의 관계에서 시스템 품질과 인터페이스 디자인 품질은 사용자 만족에 유의한 영향을 미쳤지만, 정보 품질은 유의한 영향을 미치지 않았다. 지각된 유용성은 사용자 만족과 사용의도에 유의한 영향을 미쳤으며, 사용자 만족은 사용의도에 유의한 영향을 미치는 것으로 나타났다. 본 연구의 대상인 농촌체험 앱과 경북농촌체험 앱을 비교한 결과, 지각된 유용성을 제외한 모든 변수는 유의한 차이를 나타냈다. 시스템 품질, 인터페이스 디자인 품질, 사용자 만족, 사용의도는 경북농촌체험 앱이 높게 나타난 반면, 정보 품질은 농촌체험 앱이 높게 나타났다. 이러한 연구 결과는 향후 농촌관광 정보시스템의 성공을 위한 기초자료로 이용될 수 있을 것이라 사료되며, 이를 바탕으로 시사점을 제시하였다.
