오늘날은 미디어 컨버전스 시대로 게임처럼 스토리를 선택하는 드라마를 시청하거나 영화처럼 연출하는 게임을 즐길 수 있다. 두 매체는 인터랙티브 스토리텔링을 구현하고 있으며 이 대한 논의는 오래전부터 현재까지 진행 중이다. 본 연구는 인터랙티브 스토리텔링의 새로운 브렌치 구조를 제안함과 동시에 브렌치 구조 스토리텔링 진행 방법에 대한 새로운 관점을 모색함을 목적으로 한다. 지금까지 인터랙티브 스토리텔링을 가장 잘 구현하고 있는 게임을 주된 연구대상으로 하였으며 연구결과 스토리의 내러티브를 유지하면서도 이용자가 자유롭게 상호작용을 느낄 수 있는 인터랙티브 스토리텔링 구조로서 Plot border와 Adjuster 개념을 포함한 Volume 브렌치 구조를 제안하였다. 이 구조는 게임매체 속에서 실시간 편집 영상으로만 구현할 수 있으며 지속적으로 발전하고 있는 물리엔진과 현재까지 게임에는 적극 도입되지 않고 있는 인공지능을 적용할 때 가능함을 설명하였다.

본 연구는 배추에서 벼룩잎벌레의 생태적 관리기술을 개발하고자 실험실과 포장 야외포장에서 수행되었다. 허브 식물인 바질과 레몬밤의 벼룩잎벌레에 대한 기피활성을 실험실내에서 후각계를 활용하여 측정한 결과, 벼룩잎벌레가 바질과 레몬밤을 기피하는 결과를 얻을 수 있었다. 선발된 기피식물과 유인식물로 알려진 겨자류 작물을 대상으로 포장내에서 간작과 주위작 처리했을 때의 벼룩잎벌레 억제효과를 평가하였다. 식물자원의 간작 재배효과는 시험결과 실내실험과는 달리 레몬밤 간작처리구에서 벼룩잎벌레의 밀도가 높았으며, 바질 간작처리구와 돌산갓 간작처리구에서 벼룩잎벌레의 밀도가 낮았다. 식물자원의 주위작 재배효과 시험결과 적겨자 주위작 처리와 배추 단독처리구에서 벼룩잎벌레의 밀도가 가장 높았으며, 바질과 레몬밤에서는 벼룩잎벌레가 거의 발생하지 않았다. 벼룩잎벌레 기피식물인 바질과 레몬밤 주위재배를 통해 유기농 배추 재배지에서 벼룩잎벌레의 발생을 예방할 수 있을 것으로 판단된다.

The temperature dependence of $Na^+-dependent$ succinate uptake was studied in brush border (BBMV) and basolateral (BLMV) membrane vesicles isolated from the rabbit kidney cortex. The succinate uptake was markedly altered by temperature in a similar fashion in both membranes. The temperature dependence was characterized by a nonlinear Arrhenius plot with a break point at 22 and $25^{\circ}C$ for BBMV and BLMV, respectively. The activation energy was 3.91 and 17.09 kcal/mole at above and below the break point respectively, far BBMV; 2.65 and 14.05 kcal/mole, respectively, for BLMV. When temperature increased f개m 20 to $35^{\circ}C$, the Vmax of succinate transport increased from $3.49{\pm}0.11\;to\;5.90{\pm}0.86\;nmole/mg/5\;sec$ for BBMV and from $2.86{\pm}0.25\;to\;3.63{\pm}0.32\;nmole/mg/5\;sec$ for BLMV, with no change in Km in both membranes. These results suggest that renal dicarboxylate transport is similarly sensitive to a change in membrane physical state in BBMV and BLMV.

Solvolyses rate constant of 1- and 2- naphthoyl chlorides (1 and 2) are reported for aqueous binary mixtures with methanol, ethanol, fluorinated alcohol, acetonitrile and dioxane. Kinetic solvent isotope effects (KISE) in methanol and product selectivities (S) of 2-naphthoyl chloride (2) in alcohol-water are also reported. Dispersions in Grunwald-Winstein correlations $(r{\leq}0.901)$ are discussed by multiple regression analysis incorporating ionizing power $(Y_{Cl})$ scale and rate-rate profiles. Major causes for these phenomena are investigated as an aromatic ring solvation effects, in conjunction with weakly nucleophilic solvation effects ($S_N2$ character), for solvolyses of 1 and for solvolyses of 2, as dual reaction channels, described as $S_N1$-$S_N2$ and $S_AN$-$S_N2$ processes. Distinct border lines between the two pathways are derived from solvolyses rates of 2 in 18 solvent using the results of $log(k/k_o)=mY_{Cl}+lN_T+hI$ plot with values of 1.13 for m, 0.37 for l and 0.15 for h value in 5 aqueous fluorinated alcohol mixtures. Using rate-product correlation, the validity of a third order model based on a general base catalyzed by solvent and contribution from these rate constants, $k_{aa},\;k_{aw}$ and $k_{aw}$, are investigated for $S_AN$-$S_N2$ solvolyses of 2 favored in more rich alcohol media and gradual addition of water to alcohol solvent shows a great shift away from stoichiometric solvation to predominantly medium effects. Rate-rate correlation between solvolyses of 2 and trimethyl acetylchloride (5) with alkyl group in the 29 aqueous solvent mixtures shows appreciable linearity (slope = 0.84, r = 0.987), caused by the same pathway ($S_N1$-$S_N2$ process), even if this correlation coincides with appreciable dispersion (different solvation effect).

Traditional agriculture mostly focused on activity in the field, but current agriculture faces problems such as reduction of agricultural inputs, labor shortage and so on. Accordingly, traditional agricultural experiments generally considered the simple treatment effects, but current agricultural experiments need to consider the several and complicate treatment effects. To analyze such several and complicate treatment effects, data collection has the first priority. Remote sensing is a quite effective tool to collect information in agriculture, and recent easier availability of UAVs (Unmanned Aerial Vehicles) enhances the effectiveness. LAI (Leaf Area Index) is one of the most important information for evaluating the condition of crop growth. In this study, we utilized UAV with multispectral camera to evaluate plant-based LAI of sweetcorn in a small-scale field experiment and discussed the feasibility of a new experimental design to analyze the several and complicate treatment effects. The plant-based SR measured by UAV showed the highest correlation coefficient with LAI measured by a canopy analyzer in 2018 and 2019. Application of linear mix model showed that plant-based SR data had higher detection power due to its huge number of data although SR was inferior to evaluate LAI than the canopy analyzer. The distribution of plant-based data also statistically revealed the border effect in treatment plots in the traditional experimental design. These results suggest that remote sensing with UAVs has the advantage even in a small-scale experimental plot and has a possibility to provide a new experimental design if combined with various analytical applications such as plant size, shape, and color.
