Minkyeong Kim(김민경),JaeYeol Rheem(임재열) 대한전자공학회 2019 전자공학회논문지 Vol.56 No.1

실물화상기는 수업에서 문서를 큰 스크린에 투영하여 피드백을 주는 용도로 사용할 수 있다. 하지만 사용자의 손에 의하여 문서가 가려지는 영역이 발생함으로서 인식에 불편함이 발생한다. 이를 개선하기 위하여, 가려진 영역이 투영되도록 영상을 복구하는 알고리즘을 제안하였다. 제안된 알고리즘은 손 또는 펜에 의해 가려진 영역을 검출하고, 검출된 영역을 제거한다. 제거된 영역에 원 문서로 대체함으로서 위의 단점을 개선하였다. 하지만 문서의 어느 방향을 가리키고 있는지 인식할 필요가 있기 때문에, 흔적을 남도록 영역을 제거하는 방식을 택하였다. 완벽하게 영상을 복구하기 위해, reference 영상은 실시간으로 문서가 이동하거나 사용자가 필기를 하는 경우에 업데이트되도록 구현하였다. A visual presenter is used for projecting documents on a big screen to give a feedback in a class. Occasionally, people can not see clearly the projected image when a user’s hand blocks it. To overcome this, we propose occluded region detection and image restoration algorithm. It detects the occluded region by the hand, pens and so on, eliminates the detected region and replaces the blocked region as that of the original document image showing. But we leave the trace (vestige) to recognize the hand indicating. For restoring it perfectly, the reference image updates in real-time when the document is shifted or the user writes something new.

Minkyeong Kim,Jae Soon Hwang,Yong Seub Shin,Woo-Sik Jo 한국버섯학회 2018 버섯 Vol.22 No.1

The cultivation of Poria cocos on tree-stumps and logs, was first described at the beginning of the 13th century. Poria cocos has been used for medicinal purposes to treat physical and mental recuperation, promote diuresis, forgetfulness and physical weakening. The artificial cultivation techniques of P. cocos was reported in China in 1957. are reported. The basic study on morphological characteristics and artificial cultivation method of Poria cocos with pine tree log buried under ground were initiated by Rural Development Administration. To widen the utilization of harvested sclerotia of Poria cocos as new food stuffs, powder of the sclerotia were used for producing new soft drinks and supplemented to wheat flour to make functional bread. ○ Bokryeong tree cultivation GB2, GB3, GB4, GB5, GB7, GB8, GB9, GB10, Bekryeong 1, Andong 1 and Andong 3. It is the result of investigation on the characteristics of the aged dates derived from the encapsulation cultivation of Bykryeong. As a result of measuring the number and weight of fruiting bodies, relatively large elongation was induced in Bokryeong No.1 and crossed strain GB4, and the L value of GB9 was measured relatively high in the skin color of fruiting body. The cut surface chromaticity was measured to be low in GB5. ○ Glass bottle production The result of inducing the aging in the glass bottle was as follows is the photograph of the pine tree in the glass bottle, and taken after removing the glass bottle. Crosses GB1-10 and Bokryeong No.1, Korea Forest Service 1104, Korea Forest Service 1105. The weight, size and chromaticity of the pine trees were investigated. As a result of measuring the number and weight of fruiting bodies, GB3 and GB4 produced comparatively large agglomerates and the fruity body skin color GB7 was high.

Minkyeong Pi(피민경),Seunghee Ha(하승희) 한국언어청각임상학회 2018 Communication Sciences and Disorders Vol.23 No.2

배경 및 목적: 본 연구는 24개월에 부모 보고에 의해 상이한 표현언어수준을 보인 구개열 아동을 추적 관찰하여, 36개월에 이르렀을 때 자발화에 나타난 음운 및 언어 발달 특성을 살펴보고자 하였다. 방법: 24개월에 표현언어가 지연된 구개열 아동 7명을 표현언어지연 구개열 아동, 표현언어가 정상인 구개열 아동 6명을 정상언어발달 구개열 아동으로 구분하였으며, 비교 집단으로 일반 아동 7명을 포함해 총 20명의 아동을 대상으로 하였다. 대상자들이 36개월에 이르렀을 때 세 집단의 자발화 50발화에 나타난 음운 및 언어 발달 양상을 살펴보았다. 결과: 표현언어지연 구개열 아동은 일반 아동에 비해 모든 음운지표 결과가 유의하게 낮았으며, 정상언어발달 구개열 아동과 일반 아동은 유의한 차이가 나타나지 않았다. 모든 언어지표는 세 집단 간 유의한 차이가 나타나지 않았으나 표현언어능력이 지연된 구개열 아동 중 절반은 일반 아동의 언어 발달 수준에 미치지 못하였다. 논의 및 결론: 본 연구는 초기에 표현언어능력이 지연된 구개열 아동이 이후 평균음운길이, 단어단위 근접률, 단어단위 정확도, 자음정확도, 자음목록 면에서 일반 아동은 물론 표현언어능력이 정상범주였던 구개열 아동에 비해서도 취약하다는 점을 보여주었다. 따라서 본 연구결과는 2세에 부모 보고를 통해 말·언어 발달 위험군으로 선별된 구개열 아동에게 음운 측면에 초점을 맞춘 조기 중재를 시작하는 것이 적절하다는 점을 시사한다. Objectives: The purpose of this study was to examine phonological and language outcomes of children with cleft palate (CP) at 36 months of age, who present differing levels of early language skills which were identified at 24 months of age by parent reports. Methods: The participants were 7 children with CP who presented delayed expressive language (DEL) group, 6 children with CP who presented normal language development (NLD) group, and 7 typically developing children (TD). Fifty utterances were collected from these 20 children and analyzed using phonological measures (PMLU, PWP, PWC, PCC, consonant inventories) and language measures (NDW, NTW, MLUw, MLUm). Results: DEL children with CP scored significantly lower on phonological measures when compared with TD; while the NLD children with CP showed no significant difference with the TD. No significant differences between the three groups were found in the language measures; however, half of DEL children with CP did not reach the language level of TD. Conclusion: These findings suggest that DEL children with CP have weaker later phonological skills in comparison to both TD and NLD children with CP. However, in terms of language skills, they appear to catch up to the other groups. These results suggest that early intervention with children with CP who are identified as high risk through parent reports at 24 months should aid on phonological development.

Association between phytochemical index and metabolic syndrome

Minkyeong Kim,Kyong Park 대한지역사회영양학회 2020 Nutrition Research and Practice Vol.14 No.3

BACKGROUND/OBJECTIVES: Although previous experimental studies reported the health benefits of foods rich in phytochemicals, few epidemiologic studies have investigated the associations between phytochemicals and metabolic disorders. This study aimed to calculate a phytochemical index (PI) and examine its association with metabolic syndrome in the Korean population. SUBJECTS/METHODS: Data of Korean adults aged ≥ 19 years who participated in the 2008–2016 Korea National Health and Nutrition Examination Surveys were analyzed. The PI was calculated using 24-hour intake recall data regarding whole grains, vegetables, fruits, legumes, nuts and seeds, and soybeans and soy products. Demographic and lifestyle data were obtained using self-administered questionnaires. A multivariable logistic regression was performed to calculate the adjusted odds ratios (ORs) and 95% confidence intervals (CIs) for the prevalence of metabolic syndrome and its components according to PI quintiles. RESULTS: Overall, 31,319 adults were evaluated. Compared with men, women had a higher median PI level (9.96 vs. 13.63) and significantly higher caloric intake levels from most PI components (P < 0.05), except for soy products. After adjusting for multiple confounding variables, participants in the highest PI quintile had significantly lower prevalences of abdominal obesity (OR: 0.90, 95% CI: 0.81–0.99), hyperglycemia (OR: 0.83, 95% CI: 0.74-0.94), high blood pressure (OR: 0.82, 95% CI: 0.73-0.93), hypertriglyceridemia (OR: 0.84, 95% CI: 0.75-0.94), and metabolic syndrome (OR: 0.78, 95% CI: 0.69-0.88). CONCLUSIONS: Higher intakes of phytochemical-rich foods are associated with a lower prevalence of metabolic dysregulation and consequently, cardiometabolic diseases.

Minkyeong, Kim 한국정보통신학회 2018 2016 INTERNATIONAL CONFERENCE Vol.10 No.1

The purpose of this study was to develop kinder teacher treatment play therapy for kindergarten children. SPSS version 22.0 for Windows was used for data analysis to develop kinder teacher treatment play therapy for kindergarten children. Among nonparametric statistical methods, the Mann-Whitney U Test and the Wilcoxon Singed-Rank Test were conducted. The results of this study are summarized as follows. Kinder therapy had a positive effect on the improvement of teachers’ interaction. The difference between the pretest and the posttest showed that their positive and permissive interactions improved and that their punitive and detached interactions decreased. This study shows that it is difficult to generalize the result by participation by a small number of people, but it is proved that kinder therapy is effective in improving teacher interaction ability and reducing kinder"s problem behavior in a childcare center.

Antioxidant Activity of Indigenous Trametes Species in Korea

( Minkyeong Kim ),( Chorong Ahn ),( Changmu Kim ) 한국균학회 2021 韓國菌學會誌 Vol.49 No.4

The fungal genus Trametes is globally distributed and comprises various wood-decay species, including the well-known medicinal mushroom Trametes versicolor , a popular remedy in traditional Asian medicine. Trametes species produce antioxidants, which have a wide range of health benefits. The pressent study evaluated seven indigenous Trametes species from Korea, which were cultivated in three different media (dextrose-yeast extract, DY; malt extract-yeast extract, MY; malt extract broth, MEB) and tested for antioxidant activity using the 2,2-diphenyl-1-picrylhydrazyl and 2,2’-azino-bis(3-ethylbenzothiazoline-6-sulfonic acid) assays. We found that the medium consumption rate did not significantly differ between the media and among the strains (72-76%). However, the T. versicolor strains had a relatively low consumption rate (14-65%). The 2,2-diphenyl-1-picrylhydrazyl (DPPH) and 2,2′-azinobis(3- ethylbenzothiazoline-6-sulfonate) (ABTS) tests demonstrated that culture filtrates of T. cf. junipericola, T. orientalis, T. suaveolens, and T. versicolor possessed antioxidant activity against damage from free radicals. In particular, T. cf. junipericola (DY) and T. versicolor (MY) had >80% activity in the DPPH and ABTS assays, compared with that of the positive control (ascorbic acid). Thus, our study identified promising candidates with substantial antioxidant activity among the indigenous strains of Trametes spp. from Korea.
