This study is on the characteristics of SoAUiBang(小兒醫方-pediatrics). Through this study, the characteristics of SoAUiBang(小兒醫方-pediatrics) can be organized as the following: First of all, with the issue of first edition and authorship, SoAUiBang(小兒醫方-pediatrics) was written by MongAm(夢菴) ChaeGyuHeon(崔奎憲), and it is definite that it was first published in 1912 at GwangHakSeoPo(廣學書) Secondly, the fact that SoAUiBang(小兒醫方-pediatrics) shows clear distinction in various aspects from previous pediatrics books has great academic value. As such, SoAUiBang(小兒醫方-pediatrics) maintained the form of Oriental Medicine and at the same time, took in the changes of the times.

닭가슴살의 품질변화를 실시간으로 모니터링하기 위하여 pH 지시약, AA, 다공성 기재인 $Tyvek^{(R)}$을 이용하여 신선도 인디케이터를 제조하였다. 닭가슴살의 대표적인 지표물질은 TVBN과 $CO_2$이며, 이는 저장기간에 따라 미생물의 증식과 단백질 분해를 통해 증가한다. 닭가슴살 저장실험 결과 미생물 수로 판단한 초기부패단계의 $CO_2$ 농도와 TVBN 발생량은 각각 19%와 23 mg%로 확인되었다. 지표물질 발생량 데이터를 토대로 BCG 및 AA의 농도별 인디케이터를 제조하여 인디케이터 색변화 시뮬레이션을 실시하였다. 그 결과, AA의 함량에 따른 인디케이터의 색변화구간 조절 가능성이 확인되었으며, 제조한 인디케이터 중 "G0.12_A0.5"의 인디케이터가 닭가슴살 초기 부패판정 농도인 TMA 20 mg%에서 육안으로 확인할 수 있는 뚜렷한 색변화를 보였다. 시뮬레이션을 통해 선정된 최적 조성의 인디케이터를 닭가슴살 포장내부에 부착하였으며, $4^{\circ}C$와 $10^{\circ}C$에서 8일동안 닭가슴살의 이화학적 변화와 그에 따른 인디케이터의 색변화를 관찰하였다. 그 결과, TCD 값을 통해 판단된 인디케이터의 색변화 발생일이 각 온도별 닭가슴살 초기부패판정일과 잘 부합하였으며, 이를 통해 시뮬레이션의 신뢰성을 확보할 수 있는 것으로 확인되었다. 본 연구 결과는 저장 중 닭가슴살의 품질변화를 제조한 인디케이터의 포장 내 부착을 통하여 감지하고 실시간 신선도 판단이 가능할 것으로 사료된다. To visually identify the spoilage of chicken breasts, a three layered freshness indicator consisting of PET/bromocresol green (BCG)-ethylene vinyl acetate (EVA)-acetic acid (AA) composite layer/porous substrates was successfully prepared and their performance were simulated at 20% of $CO_2$ and 4 different trimethylamine (TMA) concentrations to evaluate color change at minimal spoilage level. The visibility and range of color changes of the as-prepared indicators responding to TMA concentration as a simulant were strongly dependent on the concentrations of BCG and AA. As the BCG content increased, the visibility of color change in the freshness indicators was apparently improved and the range of color change could be controlled by contents of AA. Among the as-prepared freshness indicators, 'G0.12_A0.5' which consisting 0.12g of BCG and 0.5g of AA was selected as an optimum composition due to the highest visibility at TMA 20 mg% corresponding to the minimal spoilage level. The color of the indicator changed from yellow to green for spoilage indication of chicken breast, which could be easily seen with the naked eyes and well consistent with the simulation results. It is expected that our developed freshness indicator can be useful in monitoring various food freshness and quality.
18세기 잉글랜드와 가톨릭 계몽: 조셉 베링턴의 사상을 중심으로
이가은 한국서양사연구회 2023 서양사연구 Vol.- No.69
Previous studies of Berington, or the English Catholic Enlightenment more broadly, have tended to emphasize the progressive and radical aspects of their ideas without sufficiently considering the historical context of eighteenth-century England. Rather than focusing on the ideological consequences of the discourse, this paper examines Berington’s thoughts from the perspective of a common concern shared by a diverse group of Enlightenment thinkers: preventing the recurrence of religious wars. With this in mind, the author analyzes the ideas of Anglicans and Dissenters in the sociopolitical debates of the time and explores how Berington's language was shaped and transformed through his interactions with them. This attempt will provide a contextual understanding of why the English Catholic Enlightenment eventually took a more progressive and reformist turn.
Six Species of Moths (Lepidoptera) New to Korea
이가은,전용철 한국동물분류학회 2023 Animal Systematics, Evolution and Diversity Vol.39 No.4
As a result of investigating biodiversity of lepidopteran fauna in Korea, six species of moths within five families are reported for the first time: Bucculatrix splendida Seksjaeva (Bucculatricidae), Caloptilia isochrysa (Meyrick) (Gracillariidae), Depressaria spectrocentra Meyrick (Depressariidae), Sergeya temulenta (Omelko) (Gelechiidae), Thiotricha attenuata Omelko (Gelechiidae) and Philenora latifasciata Inoue & Kobayashi (Erebidae). Among them, Philenora Rosenstock, 1885 and Sergeya Ponomarenko, 2007 are newly recorded genera for the country. The diagnoses, redescriptions, photographs of adult and genitalia, and DNA barcode information are provided in this study.

The purpose of this study was to analyze the kinematic variables of female basketball players and obtained the data necessary for effective free throw movements and technical improvement. Using a video analysis program, it compared and analyzed between skilled and unskilled players on exercise variables such as time, body center variables, angles, and angular velocity to increase the success rate of free-throw in basketball. The results of the study were as follows; 1) as a result of the time of each phases, unskilled player appeared to be longer than skilled players from the preparation stage for free throws to the last stage of throwing the ball. 2) unskilled player had more Y-axis movement than skilled players. 3) unskilled players was not constant wrist angle like skilled player. 4) the angular velocity was low because of the lack of muscle strength of the upper and lower compared to the skilled players.
