Maintaining sea superiority through successful mission accomplishments of warships is being proved to be an important factor of winning a war, as in the Ukraine-Russia war. in order to ensure the ability of a warship to perform its duties, the survivability of the warship must be strengthened. In particular, among the survivability factors, vulnerability is closely related to a damage assessment, and these vulnerability data are used as basic data to measure the mission capability. The warship's mission capability is usually measured using a wargame model, but only the operational effects of a macroscopic view are measured with a theater level resolution. In order to analyze the effectiveness and efficiency of a weapon system in the context of advanced weapon systems and equipments, a warship's mission capability must be measured at the engagement level resolution. To this end, not the relationship between the displacement tonnage and the weight of warheads applied in the theater level model, but an engagement level resolution vulnerability assessment method that can specify physical and functional damage at the hit position should be applied. This study proposes a method of measuring a warship’s mission capability by applying the warship vulnerability assessment method to the naval engagement level analysis model. The result can be used as basic data in developing engagement algorithms for effective and efficient operation tactics to be implemented from a single unit weapon system to multiple warships.

디지털 기술은 단순한 정보 전달 수단을 넘어서, 서사를 생성하고 소비하는 방식을 재정의하는 새로운 형태 의 패러다임이다. 디지털 기술의 발전과 함께, 디지털 매체는 강력한 스토리텔링 도구로서 현대 교육 분야에 자리 잡고 있으며, 이는 전통적인 교육 방식과 비교했을 때 학습자의 상호작용이 강조된다는 차이가 있다. 본 연구는 이러한 디지털 스토리텔링 환경에서 시·청각이 결합된 정보를 학습자에게 제공하고, 스토리텔링 과정에 선택지를 제공함으로써 상호작용성과 게임 요소를 더해 학습자 스스로 스토리텔링을 통해 학습하는 방법을 제안하였다. 그리고 연구의 타당성 검증을 위해 전문가 인터뷰를 실시하였다. 전문가 검증결과, 학습 자 스스로 스토리텔링을 통해 학습하는 과정은 이해도와 몰입도 측면에서 매우 효과적일 것이라는 긍정적인 답변을 얻을 수 있었다.

This study aimed to examine the possibility of upcycling extracts of Angelica keiskei and Oenanthe javanica juice by-products through comparing enzyme extraction (EE) and complex extraction (CE) methods to increase the extraction yield and flavor of materials. A higher extraction yield was obtained for free amino acid content with EE and CE for A. keiskei and O. javanica juice by-products, respectively, and a higher extraction efficiency was achieved with juice by-products than with extracts prepared from raw materials before juice production. The content of major amino acids varied depending on the extraction method used. When used according to the characteristics of the extract, their use as a functional material was confirmed along with improvement in the flavor of the food. Consistently high extraction yields for organic acid and sugar levels were obtained with CE in A. keiskei and O. javanica juice by-products. The DPPH radical scavenging ability and TPC were consistently high with CE in A. keiskei and O. javanica juice by-products; the increase in extracted content was likely because of the reaction between the ethanol used for CE and the phenolic compounds. However, because the antioxidant capacity of the juice by-product extracts was somewhat lower than that of the extracts from raw materials before juice production, the amount used should be reviewed. The TFC was found to be higher in extracts obtained with EE than with CE for A. keiskei juice by-products; however, no significant difference was observed between EE and CE in the O. javanica juice by-products. Through this study, the taste compounds and antioxidant properties of extracts obtained from juice by-products produced after the production of A. keiskei and O. javanica green juice were analyzed, and the availability of high value-added materials was confirmed. Based on these research results, expanding specific R&D for practical use should be explored.

This study investigated the quality characteristics and optimal conditions of noodles produced by adding Baromi 2 Garu floury rice to wheat flour. The lightness of samples with floury rice increased, while the lightness (L*), redness (a*), and yellowness (b*) decreased after cooking compared to before cooking. The weight, volume, and moisture absorption rate of cooked noodles decreased compared to wheat, but turbidity increased as the amount of rice flour increased. In addition, compared to the control with 20% rice flour, GR-20 (flour replacement by 20% Garu floury rice) with floury rice had lower turbidity, showing less cooking loss. The hardness, gumminess, and chewiness of noodles with floury rice decreased as the floury rice content increased, while springiness, cohesiveness, and adhesiveness increased. The elongation force and distance decreased as the amount of floury rice increased. Therefore, the optimal amount of floury rice to replace wheat flour would be 20%. Adding excessive amounts of floury rice to processed foods requires additional processes, such as adding food additives or changing the processing method to control physical properties.

Radish is a sulfur-containing compound containing the -S group, having bioactive functions such as anticancer, antithrombotic, antioxidant, and antibacterial properties, and is used as a health supplement and pharmaceutical material. This study aimed to compare changes in sulforaphane (SFN) content according to freeze-drying or hot-air drying conditions in Korean radishes. The color of frozen or hot-air-dried radish underwent a browning reaction due to heat treatment; the brightness (L) decreased from 89.3 to 56.1, and the redness (b) increased. The SFN content of freezedried radish was 13.2565 mg/g, the SFN of radish dried at 50oC was 2.64372 mg/g, and the SFN of radish dried at 80oC was 0.0678 mg/g, which was the highest in freeze-dried radish. Therefore, the SFN of radish was found to be insufficient in thermal stability, and freeze-drying was considered a suitable method for drying radish.

본 연구는 1890년대부터 1930년대까지 한국 선교 현장에서 전도부인 들이 직면했지만 밝혀지지 않은 일상의 어려움을 밝혀내어, 토착 교회의 자립을 도모하는 개신교 선교정책인 네비어스 방법(Nevius Methods)의 포괄적인 이해를 목표로 한다. 통상적으로 지배적인 학계의 시점이 전도부 인들의 수고와 업적을 인정하는 것과는 달리, 본 연구는 전도부인들이 겪은 역경이 토착 교회의 자립을 장려했던 네비어스 방법과 밀접하게 연관되어 있음을 주장한다. 네비어스 방법은 토착 교회가 자립하도록 토착 교회가 스스로 토착 교회 사역자를 세우고 생활비를 부담해야 된다고 주장했다. 이 선교정책은 선교사들에게 한국 교회가 빠르게 성장하는 핵심 으로 여겨지고 있었지만 교회가 재정적인 어려움에 직면하게 될 때 교회 계층의 가장 낮은 위치에 있는 전도부인들이 종종 불리한 처우를 받게 되었다. 본 연구는 1차 원자료에 의존하여, 전도부인들의 경험을 철저하게 조사함으로써 토착 교회의 빠른 성장에 대한 선교사들의 열망과 가난한 선교현장의 혹독한 현실과의 격차에 대해 다룬다.
