감성에 대한 관심도는 한국을 포함하여 전 세계적으로 계속 높아지고 있으며 사회관계망서비스(SNS) 세대의 감성을 가리키는 신조어인 갬성과 더불어 최근에는 복고에 새로움을 더한 뉴트로(New-tro)와 같은 새로운 스타일이 나타났다. 감성의 특성이 시간과 환경에 대한 영향이 강하다는 점을 고려해 보면 현재의 새로운 스타일에 대한 일반인들의 감정을 알아보는 것이 필요하다. 이에 본 연구에서는 9개의 뉴트로 스타일이 적용된 제품에서 '갖고 싶다, 귀엽다, 기분이 좋다, 기쁘다, 독특하다, 멋있다, 세련되다, 예쁘다, 재미있다, 좋아하다, 즐겁다, 특별하다' 12개의 감정 어휘를 선정하였다. 설문조사의 분석 결과 남성은 '재미있다-귀엽다-기분이 좋다', 여성은 '독특하다-귀엽다-재미있다' 등의 순으로 감정의 강도가 높았고 연령대별로는 40대, 30대, 50대, 20대의 순으로 감정의 강도가 높은 것으로 나타났다. 본 연구를 통해 추출된 감정 어휘는 뉴트로 스타일이 적용된 대상의 감성을 평가하기 위해 사용될 수 있으며 제시된 분석 방법을 활용하여 구체적인 감성 평가 자료를 확보할 수 있다.

The purpose of this study is to compare and analyze the perception of retro fashion and new-tro fashion using big data. TEXTOM allowed the collection of big data on the words 'retro fashion' and 'new-tro fashion', which was refined afterwards. As for the data collection period, Jan. 1, 2019 to Nov. 30, 2022 was set. A top 50 list of words were extracted from this data based on appearance frequency. The extracted words were processed through Network centrality analysis and CONCOR analysis using Ucinet 6. The results are as follows. 1) In retro fashion, the appearance frequency of 'style' was the highest, followed by 'sensibility', 'color', 'trend', 'fashion', and 'brand'. These words came up with high TF-IDF values. Network centrality analysis discovered that 'color', 'style', 'trend', 'sensibility', and 'design' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; trends, styles, looks, and photos. 2) In new-tro fashion, the appearance frequency of 'retro' was the highest, followed by 'trend', 'generation', 'style', 'brand', and 'fashion'. These words also came up with high TF-IDF values. Network centrality analysis found that 'retro', 'trend', 'generation', and 'brand' had high level of connectivity with other words. CONCOR analysis showed a total of four significant groups; style, brand, clothing, and trend. 3) New-tro fashion is included in retro fashion in that it reproduces the styles of the past. However, it is taken completely differently from generation to generation. Unlike the older generations, millennials actively accept newly created clothes and brands based on the past styles. They perceive it as a fashion that reveals their own unique tastes and tastes.

For electrolysis process using an insoluble electrode, electrochemical performance was greatly affected by the manufacturing method and procedure, such as the firing temperature, pre-treatment, type of precursor solution, coating method, electrode material, etc. Components of the electrode therein is one of the most important factors in electrochemical reaction. To achieve such characteristics, a appropriate ratio of the electrode material should be carefully chosen. The aim of this research was to apply experimental design method in the optimization of electrode component for the maximum generation of oxidants in electrochemical oxidation process. Mixture design, especially expanded simplex lattice design, in DOME (design of mixture experiments) with Design Expert - commercial software - was used to analyze the data. Analysis of variance (ANOVA) showed a high coefficient of determination ($R^2$) value of 0.9470, thus ensuring a satisfactory adjustment of the $3^{rd}$ order special cubic regression model with the experimental data. The application of response surface methodology (RSM) yielded the following regression equation, which is an empirical relationship between the TRO generation concentration and independent variables(mol ratio of 3 electrode components) in a real unit: TRO generation concentration $(mg/L)=TRO\;conc.=98.25{\times}[Ir]+49.71{\times}[Sn]+95.29{\times}[Sb]-16.91{\times}[Ir]{\times}[Sn]-29.47{\times}[Ir]{\times}[Sb]-22.65{\times}[Sn]{\times}[Sb]+703.19{\times}[Ir]{\times}[Sn]{\times}[Sb]$. The optimized formulation of the 3 component electrode for an high TRO (total residual oxidants) generation was acquired at mol ratio of Ir 0.406, Sn 0.210, Sb 0.384 (desirability d value, 1).

The purpose of this study is to analyze the granny look of the new-tro trend via Alessandro Michele's Gucci collection and to provide a reference standard for future design developments by identifying the representation of the granny look. To analyze the new-tro trend and the granny look, basic concepts were analyzed through aesthetic and art books and the photographic data were collected through Internet sites. A total of 186 fashion images were considered as granny look by five clothing experts. The images were subdivided into silhouettes and items, materials, patterns, and colors to analyze the modeling factors and identify the intrinsic inner meaning based on the theory of Nostalgia. The analysis showed that the silhouette was expressed naturally without exaggeration or shrinkage. The thermosetting materials included fur, velvet, knit and quilted materials, while the colors showed raw and faded shades based on the use of natural colors. The patterns were mostly natural, such as flowers, leaves, and stalks, which were aimed at nature. The inner meaning of the granny look is based on the theory of Nostalgia, primarily because it is an emotional fairy tale and second, it reflected the sessions of nature. Also, it is a reinterpretation of the narrative. In conclusion, the academic and fashion industries need to understand the various emerging trends in accordance with the social and cultural backgrounds to derive a positive benefit.

This study was conducted to investigated the possibility of inactivating wilt germs (Fusarium oxysporum f. sp. radicis lycopersici) using Dielectric Barrier Discharge (DBD) plasma in a hydroponic system. Recirculating hydroponic cultivation system for inactivation was consisted of planting port, LED lamp, water tank, and circulating pump for hydroponic and DBD plasma reactor. Two experiments were conducted: batch and intermittent continuous process. The effect of plasma treatment on Total Residual Oxidants (TRO) concentration change, Fusarium inactivation and growth of lettuce were investigated. In the batch experiment, most of the Fusarium was inactivated at a TRO concentration of 0.15 mg/L or more at four-day intervals. There was no change in lettuce growth after two times of plasma treatment for one week. The intermittent continuous experiment consisted of 30-minute, 60-minute, and 90-minute plasma treatment in 2 day intervals and 30-minute treatment a one-day; most of the Fusarium was inactivated only by treatment for 30-minute every two days. However, if inactivation under $10^1CFU/mL$ is required, it will be necessary to treat for 60 minutes in 2 day intervals. The plasma treatment caused no damage to the lettuce, except the 30 min plasma treatment ay the one-day interval. It was considered that the residual TRO concentration was higher than that of the other treatments.

본 연구는 넙치 양식장 시설 내로 유입되는 병원 미생물을 효과적으로 관리하기 위한 오존 처리 기준을 마련하고자 수행되었다. 유수식 환경에서 오존 주입량을 $0.3{\sim}3.0mg\;O_3L^{-1}$의 범위로 주입하면서 3분의 반응시간을 가진 후 ORP 320~410 mV에서 TRO가 $0.01{\pm}0.01mg\;L^{-1}$가 검출되었으며, 600 mV와 700 mV에서 $0.07{\pm}0.02mg\;L^{-1}$와 $0.16{\pm}0.03mg\;L^{-1}$가 검출되었다. 오존 처리에 따라 총세균수는 80.6~97.9%의 제거율을 나타내어 오존 처리를 통한 미생물 제거효과는 분명하게 나타났다. 230 g 넙치를 $8.0kg\;m^{-2}$ 밀도로 사육한 300~400 mV 실험구에서는 총세균수는 가장 낮은 값을 보였다. 특히 400~500 mV에서 Vibrio spp.와 그램음성균은 거의 검출되지 않았다. 일간사료섭취율은 300~500 mV에서 0.7% 이상을 나타내어 대조구인 자연해수보다 감소하지 않아 부작용이 적은 것으로 나타났다. 넙치 양식장으로 유입되는 병원 미생물은 유입수의 ORP 400 mV 수준에서 효율적으로 제거되는 것으로 조사되었다.

해수중 잔류옥시던트(TRO) 농도를 0.1, 0.3 및 0.5 mg/liter로 조정하고 시간 경과에 따른 농도의 안정성을 관찰한 결과 0.1 mg/liter의 경우 측정 20분까지는 변화를 보이지 않았고, 0.3 및 0.5 mg/liter 에서는 1시간 경과시까지 안정하였다. 해수를 오존처리하여 해수중에 생성되는 TRO를 이용하여 해산어류 병원세균인 Edwardsiella tarda, Vibrio sp., Streptococcus sp., Staphylococcus sp.에 대한 살균효과를 실험한 결과 0.1 mg/liter에서 3분간의 처리로 99.9% 이상, 0.3~0.5 mg/liter에서는 30초에서 1분간의 반응시간으로 99.99% 이상이 살균되어졌다.

뉴트로가 게임 산업에 새로이 영향을 끼치는 트렌드로 부상하고 있다. 본 연구는 이와 관련해 필요성이 강조되고 있는 한국 게임 아카이빙에 주목해 그 현황을 분석했다. 그 결과, 한국 게임 아카이빙은 방법론의 부재로 인해 일관성과 타당성이 결여되었음을 파악했다. 따라서 본 연구는 게임 아카이빙 방법론을 구축하는 시론적 연구를 행한다. 먼저 도큐멘테이션 전략을 비롯한 기록학의 담론과 타 분야 문화 콘텐츠 아카이빙 연구를 분석해 방법론의 이론적 토대를 명시한다. 이후 이를 한국 게임 아카이빙에 적용하여, 게임 아카이빙 방법론을 구체화한다.
