This study was undertaken to determine the effects of fish oil supplementation with low dose on the lipid content and fatty acid composition of breast milk. Among 18 lactating women who were exclusively breast-fed their babies, 6 were in control group and 12 were in fish lil groups. The subjects in fish oil groups were supplemented with 1.96g/d or 3.92g/d of fish oil for 2 weeks from 10 to 12 weeks of postpartum. All subjects consumed their usual diet at home. Breast milk samples were collected at the final day of experiment. By fish oil supplementation, the concentrations of triglyceride, cholesterol, free fatty acid and phospholipid as well as total lipid in breast milk tended to increase, but not significant. There was no dose-dependent response. The fatty acid composition of breast milk was not changed by fish oil supplementation. These results suggest that low dose of fish oil supplementation may increase of lipid content, but does not affect on the fatty acid composition of breast milk.

랩 음악은 장르 특성상 곡에서 가사의 중요성이 매우 크고, 가사 전달을 리듬 중심으로 하기 때문에 가사의 리듬, 운율이 부각된다. 랩 음악 가사의 내용과 운율에 대해 살펴보기 위해 지난 10년간 랩 음악 장르에서 전 세계적으로 가장 큰 인기를 얻고 있는 작사가 겸 가수Drake 와 Lil Wayne 의 곡 23곡을 선정하여 그 내용과 가사 운율을 살펴본다. 내용은 공통적으로 과시를 가장 많이 사용하였으며, 사랑, 유흥 등의 가사에서는 두 작사가의 차이를 보였다. 운율은 두 작사가 모두 규칙적 운율을 주로 사용하였으며, 그 안에 여러 가지 방법을 통해 불규칙성을 더했고, 그 방법을 사용하는 빈도가 다름으로서 운율 사용방식의 차이점을 보였다.

This study was undertaken to investigate intake and consumption behavior of dairy products in college students in order to identify a better way to increase milk consumption. This survey was carried out through questionnaires. The subjects were 307 college students in ChungJu. A total of 98.3% students thought milk as good for health but only 21.5% of them drank it everyday. Most students reported drinking milk two to three times a week. Male students reported drinking milk for drinking, whereas females students for nutrition. College students preferred flavored milk rather than plain milk. Students preferred the drink-type yogurt among the dairy products. The major reason for drinking fermented milk was taste. After drinking the fermented milk, 39.1% of female students thought that fermented milk could prevent constipation. Most students thought that better taste and quality of milk and milk product would increase their consumption.

Lithiated transition metal oxides such as LiMn2O4, Lil-xMnO$_2$, LiNiO$_2$, LiCoO$_2$, and their solid solution phases are used as cathode materials for lithium rechargeable batteries. We prepared the cathode materials using a novel eutectic self-mixing method without any artificial mixing procedures. This method provides an extraordinarily simple way to make the cathode materials, and it is possible to prepare at very low temperature such as 25$0^{\circ}C$. Furthermore, the cathode materials produced have discharge capacities that are much better than cathode materials prepared by previously reported synthetic methods. The spontaneous and homogeneous mixing is verified by $^{7}$ Li magic-angle-spinning (MAS) NMR spectroscopy.

Panax ginseng ginsenosides were examined for their affects on the DNA synthesis. The DNA 1 synthesis was measured by the thymidine incorporation into NIH3T3 cells. The ginsenoside, panaxytriol, $Rh_1$ and $Rh_2$ showed reduced [$^{3}H$]-thymidine incorporation. However, other ginsenosides of $Rh_1$, $Rh_2$ and $Rh_3$ did not inhibit DNA synthesis. Among the various ginsenosides, ginsenoside $Rh_2$ was found to be the most inhibitory on DNA synthesis. We suggest $Rh_2$ as one of the potential choice of antiproliferative drugs.

With the increasing popularity of computer-generated virtual influencers, the trend is rising especially on social media. Famous virtual influencer characters Lil Miquela and Imma were all created by CGI graphics workflows. The process is typically a linear affair. Iteration is challenging and costly. Development efforts are frequently siloed off from one another. Moreover, it does not provide a real-time interactive experience. In the previous study, a real-time graphic workflow was proposed for the Digital Actor Hologram project while the output graphic quality is less than the results obtained from the CGI graphic workflow. Therefore, a real-time engine graphic workflow for Virtual Influencers is proposed in this paper to facilitate the creation of real-time interactive functions and realistic graphic quality. The real-time graphic workflow is obtained from four processes: Facial Modeling, Facial Texture, Material Shader, and Look-Development. The analysis of performance with real-time graphical workflow for Digital Actor Hologram demonstrates the usefulness of this research result. Our research will be efficient in producing virtual influencers.

본 논문은 슈피리어호 남부에 분포하는 선캠브리아기의 염기성 암맥들에 대하여 마그마의 기원과 그들이 생성될 당시의 지구조적인 환경을 알기 위하여 암석 및 지화학적인 연구가 행하여 졌다. 46개의 시료에 대한 주성분, 미량원소 및 희토류 원소들에 대한 화학분석이 이루어졌다. 이들의 화학성분은 전형적인 콘티넨탈 쏠레아이트 (contiental tholeiite)의 성격을 띄우며, 다소 철성분이 부화된 분화경향을 나타낸다. 부동원소 (immobile element)들을 이용한 tectonic discrimination diagram 에 의하면 모 마그마는 현재의 T-type MORB와 유사한 Ti의 함량이 많은 쏠레아이틱(tholeiitic)현무암으로 사료된다. 분화가 진행될수록 암석의 화학적 성질은 지각과의 동화작용(crustral asimilation)에 의해 많은 영향을 받는 것으로 나타난다. 분화가 많이 진행된 암석들은 Rb, K, Ba, Th 과 같은 LIL원소의 증가를 보인 반면에 Nb, P, Ti과 같은 HFS 원소들은 그들과 물리, 화학적 성질이 비슷한 이웃한 원소들보다 현저한 감소를 나타내었다. 이러한 특징은 마그마의 기원에서 유래된 것 뿐만 아니라 지각과의 동화작용이 병행함으로 기인되었다고 사료된다. 이 암석들의 지화학적 특성을 살펴보면 지각의 섭입과 관련되어(subduction related)생성된 암석의 화학성분과는 현저한 차이를 나타내며, 판(板)내에서 생성된 현무암(Within plate basalt)과 해양지각에서 형성된 현무암 (MORB)에서 보이는 특성을 나타낸다. 이러한 지화학적인 특성을 살펴볼 때 이 암석들은 rifting과 같은 extensional tectonic 환경에서 생성된 것으로 사료된다.

Let {$X_n;n\;\geq\;1$} be a strictly stationary sequence of negatively associated random variables with mean zero and finite variance. Set $S_n\;=\;{\sum}^n_{k=1}X_k$, $M_n\;=\;max_{k{\leq}n}|S_k|$, $n\;{\geq}\;1$. Suppose $\sigma^2\;=\;EX^2_1+2{\sum}^\infty_{k=2}EX_1X_k$ (0 < $\sigma$ < $\infty$). We prove that for any b > -1/2, if $E|X|^{2+\delta}$(0<$\delta$$\leq$1), then $$lim\limits_{\varepsilon\searrow0}\varepsilon^{2b+1}\sum^{\infty}_{n=1}\frac{(loglogn)^{b-1/2}}{n^{3/2}logn}E\{M_n-\sigma\varepsilon\sqrt{2nloglogn}\}_+=\frac{2^{-1/2-b}{\sigma}E|N|^{2(b+1)}}{(b+1)(2b+1)}\sum^{\infty}_{k=0}\frac{(-1)^k}{(2k+1)^{2(b+1)}}$$ and for any b > -1/2, $$lim\limits_{\varepsilon\nearrow\infty}\varepsilon^{-2(b+1)}\sum^{\infty}_{n=1}\frac{(loglogn)^b}{n^{3/2}logn}E\{\sigma\varepsilon\sqrt{\frac{\pi^2n}{8loglogn}}-M_n\}_+=\frac{\Gamma(b+1/2)}{\sqrt{2}(b+1)}\sum^{\infty}_{k=0}\frac{(-1)^k}{(2k+1)^{2b+2'}}$$, where $\Gamma(\cdot)$ is the Gamma function and N stands for the standard normal random variable.

There is considerable interest in the isolation of potent radical scavenging compounds from natural resources to treat diseases involving oxidative stress. In this report, four new fungal metabolites including one new bisdihydroanthracenone derivative (1, eurorubrin), two new seco-anthraquinone derivatives [3, 2-O-methyl-9-dehydroxyeurotinone and 4, 2-O-methyl-4-O-(${\alpha}$-D-ribofuranosyl)-9-dehydroxyeurotinone], and one new anthraquinone glycoside [6,3-O-(${\alpha}$-D-ribofuranosyl)-questin], were isolated and identified from Eurotium rubrum, an endophytic fungal strain that was isolated from the inner tissue of the stem of the marine mangrove plant Hibiscus tiliaceus. In addition, three known compounds including asperflavin (2), 2-0-methyleurotinone (5), and questin (7) were also isolated and identified. Their structures were elucidated on the basis of spectroscopic analysis. All of the isolated compounds were evaluated for 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity.

The influence of oxygen concentration and CO$_{2}$ as diluent in oxidizer side on soot characteristics was studied by Laser Induced Incandescence, Time Resolved LII and Transmission Electron Microscopy photography in non-premixed co flowing flames. Through the comparison of TEM photographs and the decay rate of LII signal, suitable two delay times of TIRE-LII method and signal sensitivity ($\Delta$S$_{TIRE-LII/) were determined. The effects of O$_{2}$ and CO$_{2}$ as diluent in oxidizer side on soot formation are investigated with these calibrated techniques. The O$_{2}$+CO$_{2}$, N$_{2}$, and [Ar+CO$_{2}$] mixture in co-flow were used to isolate CO2 effects systematically. The number concentration of primary particle and soot volume fraction abruptly decrease by the addition of CO$_{2}$ to the co-flow. This suppression is resulted from the short residence time in inception region because of the late nucleation and the decrease of surface growth distance by the low flame temperature due to the higher thermal capacity and the chemical change of CO$_{2}$ including thermal dissociation. As the oxygen concentration increases, the number concentration of soot particles at the inception region increases and thus this increase of nucleation enhances the growth of soot particle.
