This study investigated the effects of pectinase treatment and skin contact time on the quality characteristics of Dae-hong peach wine. Wine was produced with variations in enzyme treatment and skin contact time (1 hour, 2 hours, 1 day, 2 days, and until the completion of fermentation). Enzyme treatment increased the production yield by 6%, as well as ethanol and redness levels, compared to the non-treated control. Volatile components were higher when the skin contact time was 2 hours or 1 day. Results were compared according to enzyme treatment and skin contact time and found to be influenced by methanol and 3-methyl-1-butanol. Enzyme treatment effectively enhanced yields and volatile compound contents. However, skin contact should be concluded a day before 1 day to ensure compliance with methanol legislative requirements. Therefore, our findings show that enzymatic treatment with shorter skin contact time preserves the distinctive characteristics of Dae-hong peaches and ensures the production of safe and flavorful wine.

본고는 단국대학교 부설 한문교육연구소에서 개발 중인 특수 어휘 매칭 툴을 구동시켜 어휘 데이터의 문제점과 개선 방향을 논의하기 위해 작성되었다. 한문교육연구소 개발 어휘 매칭 툴은 최종적으로 한문 고전 텍스트를 토크나이징(Tokenizing) 하기 위한 것이며, 특수 어휘의 매칭은 전체 텍스트를 토크나이징을 하기 위한 첫 단계라고 할 수 있다. 이 어휘 매칭 툴 실행 결과를 MARKUS 자동 마크업과 비교함으로써 매칭 툴과 그 데이터의 장단점을 분석하고, 이 과정에 발견된 문제점에 대해 보완할 수 있는 방향을 제시하였다. 한문교육연구소 어휘 매칭 툴은 한문고전에 특화된 도구로서 중요한 역할을 할 수 있으며, 앞으로 한문 고전의 토크나이징 에도 기여할 것으로 기대된다. 하지만 현재 상태에서는 여러 가지 보완이 필요하다. 우선, 한국 고유의 지명과 인명 데이터를 추가할 필요가 있다. 현재 데이터는 주로 중국의 어휘에 집중되어 있어 한국 고유 어휘가 부족한 상황이다. 추가 어휘데이터를 구축함으로써 해결할 수 있을 것으 로 보인다. 또 별칭의 매칭 문제 등을 해결할 필요가 있다.

This research aims to validate the effectiveness of the "Specialized Entrepreneurship University Program," which was conducted as part of government entrepreneurship support initiatives from 2018 to 2022. Based on previous studies, a research model was derived consisting of three laboratory entrepreneurship support factors that influence program satisfaction and entrepreneurial outcomes (infrastructure support, educational mentoring support, and business linkage support). Surveys were collected and analyzed from 126 laboratory entrepreneurship firms participating in the program, and empirical analysis of the research model was conducted using SPSS 23.0 statistical software. The analysis results indicated that the three variables, namely infrastructure support, educational mentoring support, and business linkage support, were significant factors affecting program satisfaction, and program satisfaction was confirmed to influence entrepreneurial outcomes. Furthermore, it was found that the three business operation factors indirectly influenced entrepreneurial outcomes by partially mediating program satisfaction. This study is considered significant as an empirical study for the initial stage of the second-phase program enhancement, verifying the effectiveness of laboratory entrepreneurship support factors. The findings can be applied to similar government entrepreneurship support initiatives and contribute to the effective strategy and planning of stakeholders involved. The limitations of this study include the need for further research on the perception of the extent to which it contributes to entrepreneurial outcomes, emphasizing caution in interpreting the research model, and the necessity for expanding the survey population and improving survey items in future research.

본 연구에서는 부산신항에서 스크러버를 장착한 선박이 세정수를 배출하였을 때 인근 해역에 미치는 영향을 검토하기 위해 확산예측을 수행하였다. 세정수에 포함된 용존무기탄소(DIC)의 농도를 통제한 채로 세정수의 pH 조건별로 해역에 미치는 영향을 대조기 와 소조기로 나누어 평가하였다. 선박 1대에서 24시간 동안 세정수를 배출할 때, pH가 최대 0.076, 0.083 감소하였다. DIC의 경우 0.561mg/L, 0.612mg/L 증가하였다. 부산신항에 수용가능한 선박수인 24대를 전부 가정하여 실험하였을 경우 pH는 0.200, 0.545 감소하였고, DIC는 1.464mg/L, 3.629mg/L 증가하였다. 일반적으로 스크러버가 세정수를 처리하였을 때 pH 6.1인 것을 감안하여 선박 1대에서 pH 6.1인 조건으 로 24시간 동안 세정수를 배출하는 경우 우리나라 연근해의 연간 pH 변화량보다 약 33.7배 더 큰 폭으로 감소하는 것으로 계산되었다. 선 박이 24대일 경우에는 하루이상 표층의 성층화를 유발하고 수심 4m까지 영향을 주는 것으로 예측되었다.

This study was conducted to obtain basic data on domestic wild Lanopila nipponica K specimens collected in Jeollanam-do from 2015 to 2017 to investigate the characteristics of fruit bodies and analyze their nutritional components. L. nipponica K. was mainly found near hills, such as in persimmon fields around hills, on mountain trails, and in bamboo fields. L. nipponica K. occurred from July to mid-October, especially after the rainy season or a typhoon, when the air humidity was increased. Rainfall occurred for 8–15 days during the 20 days before the collection date, and the average temperature was ≥ 23oC. The size of the fruit body was 12.3–28 cm, and the weight varied depending on the size; however, the fruit body was estimated to grow overnight, reaching the size observed at its discovery. As aging progressed, the surface of the fruit body cracked, and it turned dark after 6 days. Spores were lump-shaped when the surface was cut with a knife. When the soil on the surface of the site where the fruit body was located was scratched, a white thread-shaped mycelium expanded. At the time of collection, the flesh of the fruit body was white, but it turned brown and fluffy as maturity progressed. On the sixth day after the mushroom was generated, it produced a pungent odor and became friable, resembling a black cotton ball. The surface of the fruit body was white and had a circular or elliptical shape. Crude protein content tended to be high at 59% of the dry weight. The antioxidant activity, determined using the DPPH radical scavenging analysis method, was 167 vitamin C equivalents/100 g. The spores were brown, approximately 6 μm in size, with protrusions on their surface.

곤충은 지구상의 생물 중에서 가장 많은 종을 차지하고 있다. 또 인류보다도 훨씬 오래 된 지구의 선점자이며, 환경에 대한 적응력이 뛰어나 전 세계적으로 서식하고 있다. 현대 에 접어들면서 곤충은 사람들에게 식품(식용 곤충), 치유(소리, 정서곤충) 등의 다양한 효 과를 제공하고 있지만, 사람들은 그 효과에 대해서 잘 알지 못하고 징그럽다고 생각하는 것이 대부분이다. 그래서 우리는 곤충 중에서도 울음소리로 사람들의 마음을 치유하는 소 리곤충(귀뚜라미, 여치)를 주제로 본 연구를 하였다. 본 연구는 무작위의 성인 30명을 대 상으로 소리곤충(귀뚜라미, 여치)에 대한 인지 정도를 알아보고 실제 성인들이 소리곤충 (귀뚜라미, 여치) 울음소리의 효능에 대해서 알고 있는지, 알지 못한다면 그 효능에 대해 서 알리기 위한 것이 목적이다. 이에, 본 연구를 위하여 설문지 법을 사용하였으며, 대상 자는 무작위 대상의 남녀 30명(여:18, 남:12) 이었다. 설문조사 결과로는 응답자의 과반 수가 소리곤충 울음소리에 대해서 긍정적인 답변을 보였다. 하지만 소리의 호감도에 비해 직접 소리곤충을 키울 의향이 있다는 사람은 5명(20%)밖에 되지 않았다. 이에 성인들을 대상으로 귀뚜라미나 여치 등을 키우는 체험이 활성화된다면 더욱 긍정적인 결과가 나올 것으로 판단한다.

Tempeh is a traditional Indonesian food that is fermented soybeans with Rhizopus spp. and contains high-quality protein. In this study, tempeh and yeast were set as independent variables following the central composite design to optimize the nutritional quality and sensory characteristics of high-protein loaf bread added with tempeh. The optimal mixing ratio was calculated through the response surface methodology. The optimal mixing ratio of tempehadded loaf bread was 11.27 g of tempeh and 5.46 g of yeast. A comparative analysis of the quality characteristics between the tempeh-added loaf bread and the control group produced by the optimal recipe showed that tempehadded loaf bread contained higher protein content, lower carbohydrates and fats, and lower calories. Among amino acids, essential amino acids such as aspartic acid, threonine, glycine, alanine, lysine, and histidine were significantly higher in tempeh-added loaf bread. Among fatty acids, butyric acid, capric acid, myristic acid, palmitic acid, palmitoleic acid, and heptadecanoic acid were significantly higher in tempeh-added loaf bread, while lauric acid, linoleic acid, and linolenic acid were significantly lower. This study confirmed the suitability of tempeh as an ingredient for protein-enhanced loaf bread and the potential possibility of it being utilized in bakeries.

Fluorescent probe were used to evaluate the effects of catechin on the structural parameters (annular lipid fluidity, transbilayer lateral and rotational mobility and protein clustering) of the Porphyromonas gingivalis outer membrane (OPGs). An experimental procedure was used on the basis of selective quenching of 1,6-diphenyl-1,3,5-hexatriene (DPH) and 1,3-di(1-pyrenyl)propane (Py-3-Py) by trinitrophenyl groups and radiationless energy transfer from the tryptophans of membrane proteins to Py-3-Py and DPH. Catechin increased the bulk lateral and rotational mobility, annular lipid fluidity of OPGs lipid bilayers, and had greater fluidizing efficacy on the outer monolayer than the inner monolayer. It also caused membrane proteins to cluster. Based on these effects of catechin on OPGs, the antibacterial and antiviral actions of catechin can be partially explained.

This study sought to conduct a fundamental investigation in order to test and evaluate the thermal performance of an aluminum stick curtain wall system. In terms of the thermal performance index, the infiltration rate of air tightness, thermal transmittance of the heat insulation property and temperature difference ratio of condensation resistance were experimentally measured. The research process can be divided into three parts. First of all, a database for the test report of the curtain wall was compiled and existing design criteria with respect to the evaluation method and standard of transparent building components such as curtain wall, window and door were analyzed to produce the specimens. Secondly, four different types of curtain wall specimens were created through investigating the curtain wall database. Thirdly, standard tests of thermal performance were carried out for airtightness, thermal performance and condensation resistance. As a result, the curtain wall specimens with low-e triple glazing covered by an aluminum capture system showed high thermal performance compared to other curtain wall specimens including low-e triple glazing with a 4-sided structural sealant glazing system. Air tightness of all types of curtain wall specimens satisfied level 1 standard for air tightness. It was found that a curtain wall which consists of a one track frame has difficulties meeting the residential standard of thermal performance with regard to thermal transmittance and condensation resistance.
