The purpose of this study is to create a shirt sloper suitable for an elderly male body shape by producing virtual models using a 3D-virtualization program, making a torso prototype using the Yuka CAD system, and employing 3D simulation to virtualize and calibrate the model. First, the following three types of obese dummies are implemented through the CLO 3D program: Type 1 exhibits body fat in the lower body; Type 2 exhibits an obese abdomen; and Type 3 displays a balanced form of obesity. Second, for the design of the shirt pattern, the waist back length (measured value+1), back armhole depth (C/10+12+3+0.5~1.5), front armhole depth (back armhole depth 0~1), front interscye (2C/10‒1+0.5‒0.5), armscye depth (C/10+2+3.5+ 0.5), back interscye (2C/10‒1+1), front chest C (C/4+2.5+1), back chest C (C/4+2.5‒1), front hem C (C/4+2.5+1(+2)), back hem C (C/4+2.5‒1(+2)), cap height (AH/3‒5), and biceps width (Front AH‒1, Back AH‒1) are calculated. Third, the virtual attachment of the shirt pattern is resolved by increasing the front and back armhole depths, and the front and rear wrinkles are improved by adding a back armhole dart. The front hem lift and lateral pull caused by the protrusion of the abdomen are amended by increasing the margin of the chest, waist C, and hip C, with the appearance improved by balanced margin distribution in the front, back, and side panels. The improved retail pattern with an increase in the front armholes C was balanced on the torso plate.

Hepatic stellate cells (HSCs) play essential roles in normal and pathophysiological function in liver. In steady state, HSCs contribute to retinoid storage, immune tolerance, and extracellular matrix (ECM) homeostasis. Upon liver injury, they become activated and lead to morphological and functional changes. Studies have demonstrated that activation of HSCs by various stimuli such as toxins, microbial infection, or metabolic overload can promote the fibrotic changes in liver by production of ECM. Herein, we provide current knowledge about the basic characteristics of HSCs and the mechanism by which they are activated.

This study examined the effects of freshwater discharge by artificial dikes from the Kanwol and Bunam lakes on the dynamics in the Chunsu Bay, Yellow Sea, Korea, during the summer season based on three-dimensional numerical modeling experiments. Model performances were evaluated in terms of skill scores for tidal elevation, velocity, temperature, and salinity and these scores mostly exceeded 90 %. The variability in residual currents before and after the freshwater discharge was examined. The large amount of lake water discharge through artificial dikes may result in a dramatically changed density field in the Chunsu Bay, leading to an estuarine circulation system. The density-driven current formed as a result of the freshwater inflow through the artificial dikes (Kanwol/Bunam) caused a partial change in the tidal circulation and a change in the scale and location of paired residual eddies. The stratification formed by strengthened static stability following the freshwater discharge led to a dramatic increase in the Richardson number and lasted for a few weeks. The strong stratification suppressed the vertical flux and inhibited surface aerated water mixing with bottom water. This phenomenon would have direct and indirect impacts on the marine environment such as hypoxia/anoxia formation at the bottom.

본 실험은 CAM 식물인 칼랑코에(Kalanchoe blossfeldiana) 에 이산화탄소 시비 및 다양한 일장처리를 통한 생육반응을 조사하여 탄소자원화 기술 도입 방안을 모색하고 고품질 분화 묘 생산을 하고자 수행되었다. 실험은 서울여자대학교 ICT스마트형 유리온실에서 실시하였으며, 공시 재료는 칼랑코에 Kalanchoe blossfeldiana ‘Lion’, ‘Fikalrudak’ 두 품종이다. 일장은 8시간, 12시간, 16시간으로 처리하였으며 이산화탄소는 22:00~04:00에 평균 400㎛ol･mol-1(대조구)와 800㎛ol･mol-1로 처리했다. 엽수는 칼랑코에 ‘Lion’ 품종의 경우, 8시간과 12시간 일장에서, 칼랑코에 ‘Fikalrudak’ 품종의 경우, 8시간 일장에서 이산화탄소 농도 상승에 따라 증가하였다. 초장은 품종에 관계없이 일장 8시간에서 이산화탄소 농도를 400㎛ol･mol-1에서 800㎛ol･mol-1로 증가시킬 때 감소하였다. 칼랑코에 ‘Lion’ 품종에서, 미성숙엽의 엽장과 엽폭은 이산화탄소 농도 상승에 따라 일장 8시간과 12시간에서 증가하였다. 하지만, 칼랑코에 ‘Fikalrudak’ 품종의 미성숙엽 엽장과 엽폭은 이산화탄소 농도에 영향을 받지 않아 품종에 따른 반응 차이가 있는 것으로 판단된다. 마디수는 품종과 일장에 관계없이 이산화탄소 농도를 800㎛ol･mol-1로 증가시켰더니 증가하였으며, 개화소요일 수는 이산화탄소 농도에 영향을 받지 않았다. 개화는 품종에 따라 차이가 있었으며 칼랑코에 ‘Lion’ 품종에서는 8시간과 12시간 일장에서, 칼랑코에 ‘Fikalrudak’ 품종에서는 8시간 일장에서 나타났다. 이상의 결과로 칼랑코에는 이산화탄소 농도에 관계없이 단일 조건에서만 효과적으로 개화하며, 이산화탄소 시비는 칼랑코에 잎의 생산과 마디 생산을 촉진시킬 수 있었 다. 그러나 이산화탄소 고농도 시비는 칼랑코에 개화 품질에 부정적인 영향을 줄 수 있으므로 시비 단계, 품종 등에 따른 적합한 시비 방법이 다르게 적용되어야 한다.

본 연구는 제비동자꽃의 대량번식을 위한 효과적인 발아 조건을 선발하고자 수행되었다. 제비동자꽃 종자는 저온습윤 처리(5°C, 0, 4, 8, 12, 16주), GA3 처리(0, 500, 1000mg･L-1), 프라이밍 처리(0.1M, 0.2M의 NH4NO3, K2HPO4, KCl, KNO3)를 하였다. 모든 종자는 25°C, 12시간 광조건(40μmol･m-2 ･s-1)에 서 발아 실험이 진행되었으며, GA3 처리구는 비닐온실(평균 23.4°C)에서도 비교실험이 진행되었다. 저온습윤 8주 처리구 에서 20.4%로 가장 높은 발아율을 나타냈으며, 12주 이상의 저온습윤 처리는 오히려 제비동자꽃의 발아율을 감소시켰다. GA3 0, 500, 1000mg･L-1 처리된 종자는 25°C에서 각각 3.3, 44.0, 62.0%, 비닐온실에서 각각 5.3, 16.7, 42% 발아하였다. 제비동자꽃 종자는 GA3 농도가 높아질수록 발아율이 증가하였다. 또한 제비동자꽃 종자는 0.2M KNO3-프라이밍 처리구에서 가장 높은 발아율(54.7%)을 나타냈으며, 평균발아소요일수는 처리 간 유의성을 보이지 않았다. 이상의 결과로 효과적인 제비종자꽃 종자 번식을 위한 전처리 조건으로 24시간 GA3 1000mg･L-1 침지 처리 또는 0.2M-KNO3 프라이밍 처리를 추천한다.

This study presents an efficient clothes-sizing system for those experiencing obesity in old age with the aim of revitalizing the clothing industry for older obese people. The study targets 249 obese men aged 60 to 85 who satisfy a Rohrer index score of 1.6 or higher and a BMI (body mass index) of 25 or higher. Elderly obese males showed more obesity in the body based on the waist. In particular, those in their 60s were the most obese, and after reaching their 70s, characteristics of old age in which the stature was reduced and the limbs were tapered were shown. The clothes-sizing system was set to 5cm in stature, 5cm and 3cm in chest girth, 2cm in waist girth (omphalion), and 2cm in hip girth according to the KS standards. Through the two-way distribution of each section, the name of the section with a high distribution was given. Casual tops were selected from eight sizes, ranging from 155 to 170cm in stature and 95 to 105cm in chest girth. Suit top sizes were selected from eight sizes, ranging from 160 to 170cm in stature and 94 to 103cm in chest girth. Bottoms suggested 10 sizes distributed between 90 and 100cm in waist girth (omphalion) and 92 and 98cm in hip girth. According to the KS standards, the detailed size was divided into the basic part and the reference part.
