오판진(Oh, Pan-jin),유상언(Yoo, Sang-eon) 학습자중심교과교육학회 2022 학습자중심교과교육연구 Vol.22 No.7

Objectives The purpose of this study is to analyze how to hold a pencil in the first grade of elementary school Korean and to find ways to help students write correctly. Methods A case study method was used among the qualitative studies, and interviews with Yoo Sang-eon for a single case of how to hold a pencil, Hangul files related to his claims, YouTube materials, student handwriting materials, and testimonials were used in this study. Textbooks and teacher s guides were analyzed in a multi-layered manner, along with texts and letters. Results As a result, it was found that there was a problem with the position of the finger guiding in the current 2015 revised curriculum for the first grade textbook. In other words, if you look at the position of your fingers when writing, holding a pencil while holding your thumb and index finger in a circle is not the optimal way. Also, it is not appropriate to place your elbows on the desk when writing, so it is a guideline that needs to be corrected. On the other hand, Yoo Sang-eon s method of holding a pencil is a better way to help students write correctly. Here s how to hold a pencil correctly, as he suggests. First, put the tip of the thumb and middle finger together to make a round shape, and then place the pencil on the nail area of the middle finger and the area next to the bone where the index finger begins. Second, lift your thumb upwards, bend it at a right angle, and press the pencil gently from above. Third, bend the forefinger close to a right angle and put it lightly between the thumb and middle finger without straining. Fourth, write in such a way that the wrist or arm where you are writing extends slightly over the edge of the desk. Conclusions If you write according to the shape and position of the finger holding the pencil as suggested by Yoo Sang-eon, the force of the finger applied to the pencil is maintained evenly, so that you can write more correctly. 목적 이 연구의 목적은 초등국어 1학년의 연필 잡는 법을 분석하고, 학생들이 바른 글씨를 쓰도록 돕는 방안을 모색하는 데 있다. 방법 이 연구에서는 질적 연구 가운데 사례 연구라는 연구 방법을 사용하였고, 유상언의 연필 잡는 법이라는 단일 사례를 대상으로 그와의 인터뷰 자료와 그가 주장하는 내용과 관련한 한글 파일, 유튜브 자료, 학생들의 글씨 자료, 소감문이나 편지글 등과 함께 교과서와 교사용지도서를 다층적으로 분석하였다. 결과 그 결과 현행 2015 개정 교육과정 1학년 교과서에서 안내하고 있는 손가락의 위치에 문제가 있다는 것을 발견하였다. 즉, 글씨를 쓸 때 손가락의 위치를 보면, 엄지와 검지를 둥그렇게 모으면서 연필을 잡는 방법은 최적의 방법이 아니라는 것이다. 그리고 글씨를 쓸 때 팔꿈치를 책상 위에 올리도록 한 것도 적절하지 못해서 수정해야 할 지침이다. 이와 달리 유상언이 제안하는 연필을 바르게 잡는 방법은 학생들이 글씨를 바르게 쓰는 데 도움을 주는 더 나은 방법이다. 그가 제안하는 연필을 바르게 잡는 방법은 다음과 같다. 첫째, 엄지손가락과 가운뎃손가락 끝을 맞잡아 둥글게 만든 후 가운뎃손가락의 손톱 부위와 집게손가락이 시작되는 뼈 옆 부위에 연필을 올린다. 둘째, 엄지손가락을 위로 들어서 직각으로 꺾은 후 연필을 위에서 지그시 눌러 준다. 셋째, 집게손가락도 직각 가깝게 꺾어서 엄지와 가운뎃손가락의 사이에 힘주지 않고 살짝 붙여만 준다. 넷째, 글씨 쓰는 손목이나 팔이 책상 모서리에 약간 걸치는 정도로 해서 글씨를 쓴다. 결론 유상언이 제안하는 연필 잡는 손가락의 모양과 위치에 따라 글씨를 쓰면, 연필에 가해지는 손가락의 힘이 균등하게 유지되어 편안한 자세로 글씨를 더 바르고 쉽게 쓸 수 있다.

KYDISC: Galaxy Morphology, Quenching, and Mergers in the Cluster Environment

Oh, Sree,Kim, Keunho,Lee, Joon Hyeop,Sheen, Yun-Kyeong,Kim, Minjin,Ree, Chang H.,Ho, Luis C.,Kyeong, Jaemann,Sung, Eon-Chang,Park, Byeong-Gon,Yi, Sukyoung K. American Astronomical Society 2018 The Astrophysical journal Supplement series Vol.237 No.1

<P>We present the KASI-Yonsei Deep Imaging Survey of Clusters targeting 14 clusters at 0.015 less than or similar to z less than or similar to 0.144 using the Inamori Magellan Areal Camera and Spectrograph on the 6.5 m Magellan Baade telescope and the MegaCam on the 3.6 m Canada-France-Hawaii Telescope. We provide a catalog of cluster galaxies that lists magnitudes, redshifts, morphologies, bulge-to-total ratios, and local density. Based on the 1409 spectroscopically confirmed cluster galaxies brighter than -19.8 in the r band, we study galaxy morphology, color, and visual features generated by galaxy mergers. We see a clear trend between morphological content and cluster velocity dispersion, which was not presented by previous studies using local clusters. Passive spirals are preferentially found in a highly dense region (i.e., cluster center), indicating that they have gone through environmental quenching. In deep images mu(r' )similar to 27 mag arcsec(-2)), 20% of our sample shows signatures of recent mergers, which is not expected from theoretical predictions and a low frequency of ongoing mergers in our sample (similar to 4%). Such a high fraction of recent mergers in the cluster environment supports a scenario that the merger events that made the features have preceded the galaxy accretion into the cluster environment. We conclude that mergers affect a cluster population mainly through the preprocessing of recently accreted galaxies.</P>

In this paper, we propose an algorithm of setting region of interest(RoI) using R-CNN and tracking it. This algorithm is designed to apply to the system that automatically recognizes the surrounding environment information of agricultural UAV. The suggested algorithm can be divided into three main categories. The first step is the feature extraction for region proposal. The direction of gradient based on histogram of gradient(HOG) is applied to detect all characteristics of mobile objects, and random Hough transform is applied to search for ground and stationary objects. The second step is deep-learning for recognition. In this step, we used R-CNN method which need to set region proposal. Extracted feature from the first step helps to get RoI. The data information was then learned to Convolutional Neural Network with a sample of 1000 images per each categories. The third step is tracking RoI. The recognized objects are then tracked and the position data is input into the database in real time to accumulate. The direction is predicted and tracked based on cumulative data, even if objects overlap or are temporarily invisible. Assessment of the recognition and tracking performance of the object was tested using the method of Mean Average Precision(MAP) and Recall to calculate the probability of how accurate it was to detect it. Tests had shown that the MAP is 77% and the Recall is 85%, with good detection and tracking.

Baicalein (5,6,7-trihydroxy-2-phenyl-chromen-4-one) is a flavone, a type of flavonoid, originally isolated from the roots of Scutellaria baicalensis. This study evaluated the protective effects of baicalein against oxidative damage-mediated apoptosis induced by ultraviolet B (UVB) radiation in a human keratinocyte cell line (HaCaT). Baicalein absorbed light within the wavelength range of UVB. In addition, baicalein decreased the level of intracellular reactive oxygen species (ROS) in response to UVB radiation. Baicalein protected cells against UVB radiation-induced DNA breaks, 8-isoprostane generation and protein modification in HaCaT cells. Furthermore, baicalein suppressed the apoptotic cell death by UVB radiation. These findings suggest that baicalein protected HaCaT cells against UVB radiation-induced cell damage and apoptosis by absorbing UVB radiation and scavenging ROS.

The effects of ovulation induction in ussurian bullhead, Leiocassis ussuriensis, were investigated by treating ussurian bullhead with hCG, LHRHa, GnRHa, ovaprim, and pimozide. hCG was injected to ussurian bullhead at 0.75%NaCl, 5,000, 10,000, 20,000, and 30,000 IU, respectively. The ovulation inducement rates were 100% in 20,000 and 30,000IU. Fertilization rates were 82.7% and 79.8%. Hatching rates were 59.4% and 57.2%. Ovulation time was between 16-19hr The concentrations of LHRHa injected were 0.75 NaCl, 50, 100, 200, 300, and 300 μg/kg. The ovulation inducement rates were 100% in 300 and 400 ㎍/kg. Fertilization and hatching rates were 84.9% and 68.4% at 200 ㎍/kg. The times to ovulation were between 23 hr and 34 hr. Ovaprim of 0.75% NaCl, 1.0, 1.5, 2.0, 2.5 and 3.0 ml/kg were injected to the abdominal cavity. The ovulation inducement rate was highest at 2.0 and 3.0 ml/kg to 92% and ovulation time was between 27-38 hr. LHRHa concentrations of 0.75% NaCl, 50, 100, 200, 300 and 400 μg were injected with pimozide (1,000μg). Ovulation inducement rate was 100% from 200 to 400 IU with pimozide. Ovulation time was 22-36 h. Fertilization and hatching rates were 88.9% and 70.4% in 200 ㎍/kg with pimozide.

<P><B>Objective</B></P><P>This study compared the pharmacokinetic (PK) and safety profiles of a fixed-dose combination (FDC) formulation of telmisartan and S-amlodipine with those of concomitant administration of the two drugs.</P><P><B>Materials and methods</B></P><P>This was an open-label, randomized, crossover study in healthy male Koreans. All subjects were administered an FDC tablet containing 40 mg telmisartan and 5 mg S-amlodipine and were also coadministered the same dose of both drugs given separately. The crossover study design included a 14-day washout period between the two treatments. Blood samples were collected up to 168 h following drug administration. The plasma concentrations of telmisartan and S-amlodipine were determined by liquid chromatography tandem mass spectrometry. PK parameters and plasma concentration–time curves were compared. Safety was assessed by measuring vital signs, clinical laboratory tests, physical examinations, and patient interviews.</P><P><B>Results</B></P><P>The geometric mean ratios and 90% CIs for the maximum plasma concentration (C<SUB>max</SUB>) and area under the curve from time zero to the last sampling time (AUC<SUB>t</SUB>) were 0.8782 (0.8167–0.9444) and 0.9662 (0.9210–1.0136) for telmisartan and 1.0069 (0.9723–1.0427) and 1.0324 (0.9969–1.0690) for S-amlodipine, respectively. A total of 36 adverse events (AEs) were reported by 23 subjects, but no statistical differences were observed between the two treatments. The most frequently reported AE was a mild-to-moderate headache that was generally self-limiting.</P><P><B>Conclusion</B></P><P>For both telmisartan and S-amlodipine, the C<SUB>max</SUB> and AUC<SUB>t</SUB> 90% CIs were between ln (0.8) and ln (1.25). These results suggest that the FDC formulation is pharmacokinetically bioequivalent and has a similar safety profile to the coadministration of these drugs.</P>
