Second, Public and private R&D Project Leadership showed partially a interaction effect between project management and project performance.

Cette étude s’intéresse à l’utilisation du manuel de FLE(français langue étrangère) comme moyen de promouvoir et revitaliser le cours de FLEdans des universités coréennes. L’expérience a été réalisée deux fois, en 2021 et en 2022 avec 64 étudiants. Ils sont invités à répondre au questionnaire. Publié par Didier, une maison d’édition en France, en 2018, le manuel “Bonjour et bienvenue A1.1 Coréanophones” a été choisi. D’un point de vue didactique, nous avons analysé comment l’enseignant a utilisé ce manuel au cours et comment les aprenants ont ressenti le manuel. Puis, nous avons observé les effets à l’apprentissage. Par conséquent, l’enseignant poursuit le parcours proposé par le manuel mais parfois l’employe de manière éclectique en fonction de la situation en classe. Les apprenants apprécient le manuel car ils trouvent bien pouvoir terminer le manuel à la fin du cours. Ils aiment son contenu d’apprentissage et ils pensent qu’il est très utile quand ils voyagent en France ou parlent de la vie quoitidienne avec des Francophones. Certains étudiants répondent que ce manuel leur aide à pouvoir se présenter en français.

용존 6가 우라늄은 다양한 화학종으로 존재하며, 화학종의 분포는 수용액의 pH에 의존한다. 산성 및 중성 근처의 pH 환경 에서는 대표적으로 UO2 2+, UO2OH+, (UO2)2(OH)2 2+, (UO2)3(OH)5 + 화학종이 공존한다. 수용액 속에 비결정성 실리카가 콜로이드 성질의 부유입자 상태로 존재할 때 용존 화학종은 실리카 표면에 쉽게 흡착된다. 이 연구에서는 표면 흡착 화학종의 분 포가 용존 화학종의 분포를 따르는지 조사하였다. 시료의 pH 값이 3.5-7.5인 조건에서 3종의 용존 화학종(UO2 2+, UO2OH+, (UO2)3(OH)5 +)과 2종의 표면 흡착 화학종(≡SiO2UO2, ≡SiO2(UO2)OH‐ 또는 ≡SiO2(UO2)3(OH)5 ‐)의 시간 분해 발광(luminescence) 스펙트럼을 측정하였다. pH 변화에 따른 각 화학종의 스펙트럼 변화 양상을 비교한 결과로 표면 흡착 U(VI) 화학종의 분포는 용존 U(VI) 화학종의 분포와 다르다는 것을 확인하였다.

아메리슘(Am)은 사용후핵연료의 장기 방사성 독성에 크게 영향을 주기 때문에 고준위 방사성 폐기물 처분의 장기 안전성 평가에 필수적으로 고려되어야 할 원소이다. 분광학적 방법을 이용한 일부 악티나이드 원소의 화학반응 연구가 활발히 진행되고 있는 반면, 아메리슘에 대한 연구는 아직까지 미비한 상황이다. 이 연구에서는 고순도의 시료를 필요로 하는 화학반응 연구를 위하여 241Am 시료를 정제한 후, 액체섬광계수기와 감마선 및 알파선 스펙트럼을 이용하여 정량과 정성분석을 하였다. 액체 광도파 모세관 셀을 이용한 고감도의 UV-Vis 흡수 분광학과 시간분해 레이저 형광 분광학을 이용하여 Am(Ⅲ) 가수분해물과 옥살레이트(oxalate, Ox) 착물반응을 조사하였다. 산성조건에서 Am3+은 503 nm에서 최대 흡수봉우리를 보이며, 몰흡광계수는 424 ± 8 cm-1·M-1임을 확인하였다. 중성 이상의 pH 조건에서 형성되는 Am(OH)3(s) 콜로이드 입자에서는 506-507 nm 파장에서 최대 흡수봉우리가 관측되었다. Am(Ox)3 3- 착물은 Am3+에 비교하여 흡수 및 발광스펙트럼이 각 각 4와 5 nm정도 장파장으로 이동하였고 몰흡광계수와 발광세기도 크게 증가하였다. Am(Ox)3 3-의 발광수명은 23에서 56 ns으로 증가하였고 이는 Am(Ⅲ)의 내부권에 결합하고 있던 약 여섯 개의 물분자가 옥살레이트의 카르복실기로 치환되었음을 의미한다. 이 결과로부터 Am(Ox)3 3-은 각 옥살레이트 리간드가 두 자리 결합(bidentate)을 하고 있다는 것을 제안하였다.

In this study, we conducted an empirical analysis using structural equation modeling (SEM) by distributing questionnaires to 208 Chinese tourists who constitute the largest proportion of foreign tourists visiting South Korea. The survey was conducted in a face to face (FTF) manner with the aim to contribute to globalization of Korean cuisine through comprehensive analysis of the effects of preference characteristics of Korean wave dramas on the relationship among images, attitudes, and purchase intentions for Korean cuisine. The main actor characteristics among the preference characteristics of Korean wave dramas had a significant effect on the attitudes and purchase intentions for Korean cuisine. However, the thematic characteristics among the preference characteristics of Korean wave dramas did not have a significant effect on the purchase intentions for Korean cuisine; in addition, the production characteristics did not have a significant effect on the attitudes and purchase intentions for Korean cuisine. The eco-friendly and health images of Korean cuisine had a significant effect on the purchase intentions for Korean cuisine, and the attitudes toward Korean cuisine significantly affected the purchase intentions for Korean cuisine. Based on the results of this study, it is considered necessary to continuously publicize Korean cuisine through Korean wave dramas to build positive attitudes toward Korean cuisine through enhanced images of Korean cuisine.

KURT(KAERI Underground Research Tunnel) 지하수에 존재하는 천연 유기물질과 6가 우라늄(U(VI))화학종의 상호작용을 레이저 분광학 기술을 이용하여 조사하였다. 지하수 시료에 266 nm 파장의 레이저 빛을 입사시켜 자외선 및 파란색 파장 영 역에서 방출되는 천연 유기물질의 발광 스펙트럼을 관측하였다. 0.034-0.788 mg·L-1 농도 범위의 우라늄이 함유된 지하수에 서는 녹색 파장 영역에서 방출되는 U(VI) 화학종의 발광 스펙트럼을 측정하였다. 지하수에 함유된 U(VI) 화학종의 발광 특 성(피크 파장 및 발광 수명)이 실험실에서 제조한 표준용액에 함유된 Ca2UO2(CO3)3(aq)의 발광 특성과 매우 유사하다는 것 을 확인하였다. 지하수에 존재하는 U(VI) 화학종의 발광 세기는 표준용액에 함유된 같은 농도의 Ca2UO2(CO3)3(aq)의 발광 세기에 비해 약하다. 표준용액의 Ca2UO2(CO3)3(aq)를 천연 유기물질이 함유된 지하수에 섞었을 때에도 Ca2UO2(CO3)3(aq)의 발광 세기가 감소한다. 이러한 현상의 원인을 지하수의 천연 유기물질과 Ca-U(VI)-탄산염 화학종의 상호작용으로 인해 비 발광성 U(VI) 착물이 형성되기 때문인 것으로 설명하였다.

The purpose of this study was to investigate the purchasing behavior and selection attributes for Home Meal Replacement (HMR) and to identify the selection attributes affecting purchasing frequency and purchasing costs of married women living in a city. Among 837 questionnaires distributed to HMR married women consumers, 752 complete questionnaires (89.8%) were analyzed. The younger married women group showed higher frequency of purchasing HMR than the older age group. The 20s and 30s age groups showed higher purchasing costs for HMR than the 40s and older age groups. A higher proportion of employed married women purchased HMR three or more times per week and spent an average of more than 20,000 won per purchase in comparison with unemployed married women. HMR selection attributes were classified into five factors: ‘taste and sanitation’, ‘economic efficiency’, ‘health and nutrition’, ‘convenience’, and ‘reliability and awareness’; mean scores of these factors’ importance levels were 4.28, 3.93, 3.59, 3.54, and 3.50 out of 5 points, respectively. The importance level of ‘taste and sanitation’ factor was significantly greater as married women’s age decreased. However, the importance level of ‘health and nutrition’ factor was significantly greater as married women’s age increased. The results of the logistic regression analyses indicate that the ‘taste and sanitation’ and ‘health and nutrition’ factors affected frequency of purchasing HMR. The ‘reliability and awareness’ factor had the most significant impact on cost per purchasing HMR. Therefore, a product differentiation strategy according to married women’s age and employment status should be applied. Product qualities and brand value should be improved to enhance competition in the HMR market.

Ovulation resembles a tissue remodeling process such as a blood coagulation. The present study was aimed to examine the involvement of tissue factor, a primary factor for extrinsic coagulation pathway, in the ovulation. Northern blot analysis revealed that mRNA levels of tissue factor and tissue factor pathway inhibitor 2 (TFPI-2) in the ovary were stimulated by human chorionic gonadotropin (hCG) treatment in surperovulation model, of immature rats. Real-time PCR analysis demonstrated that the expression of tissue factor and TFPI-2 was stimulated in granulosa and theca cells of preovulatory follicles, respectively. The induction of tissue factor mRNA was blocked by the progesterone receptor antagonist RU486. Tissue factor protein was not detected in the ovary by Western blot and immunohistochemical analysis due to the lack of a specific antibody. Interestingly, the levels of tissue factor and TFPI-2 mRNA were increased in the ovarian cells of rats induced ovarian hyperstimulation syndrome (OHSS) and in granulosa cells of OHSS patients undergiong in vitro fertilization. The present findings indicate the stimulation of tissue factor system during ovulation, and in OHSS patients, implicating the possible involvement of tissue factor system in OHSS.

An ecological survey of food and nutrition was conducted in April and May, among 278 children, 6 to 12 years old, of the Youido elementary school, which offers no school lunch program, and is situated in Youido delta of Han River side of Seoul, known as the location of one of the socioeconomically high groups; Eighteen percent and 18.3% of subjects were proven to be overweight and obese, respectively. With regard to frequency of skipping breakfast, 28.4% of the subjects skipped breakfast often and 2.5% of subjects skipped breakfast every morning. Obese children showed good appetite and the time consumed for eating was shorter than those of normal or overweight children. Most serious anxiety among the mothers for those children was food habit of `eating rapidly' and `overeating'. Another striking observation was that 14.4% of the subjects ate only one side-dish with boiled rice, and such a pattern was more often found in the normal or slim group. Most of the subjects had their snacks after being back in home from school. Thirty-one percent of the children had snacks when they felt hungry, 69% had snacks for various reasons such as `habitually', `for unwinding', and `mother gives me snacks'. Thirty-eight percent of the boys and 19% of the girls had physical exercise everyday and overweight and obese children got exercise more frequently. But the time consumed for exercise was much more shorter than that of normal subjects. Most of the children liked fruits, meats, and biscuit, in contrast, lowest preferency was for vegetables, fermented fish products, and boiled rice mixed with other grains. Obese children experienced more kinds of food than normal or slim group. The study found that habits of overeating due to good appetite and eating rapidly were recognized as one of dominant reasons causing obesity among children. On the other hand, serious dietary problem of children of normal or slim group was eating less variety of food. Active nutrition education for both children and mothers will be recommended with joint participation of teachers.
