Among the different types of seaweed that are cultivated in Korea for food, Capsosiphon fulvescensis the filamentous green alga with the highest production value. However, its harvest yield varies significantly from year to year due to its dependence on the natural seeding method. The present study aimed to identify the conditions affecting the formation of cyst-zygotes that can be utilized as artificial seeds during the life cycle of C. fulvescens. Gametangia and zygotes of C. fulvescens were found to be highly developed at temperatures above 15°C, with a maximum gametangial development rate of about 35% observed after 7 days of culture. The formation of zygotes into cystzygotes was induced within 7 days in all temperature conditions, but after 30 days of culturing, cyst-zygotes germinated into filamentous thalli at temperatures above 20°C, while the most stable formation and stabilization were observed at 15°C. Cystzygotes formed at 15°C showed high growth when they were transferred to 25°C conditions, and zoospores matured inside the cells. The production of cyst-zygotes was mostly influenced by temperature, and a gradual increase in temperature was found to be necessary for the formation and growth of cyst-zygotes. The culture conditions facilitating the formation of cyst-zygotes reported in this study can be useful for the production of artificial seeds and breeding technology for the effective cultivation of seaweed.

In Korea, “group feeding facilities” are public establishments that offer food to large numbers of people, typically consisting of more than 50 individuals at a time. As of March 2024, there were 46,642 such meal facilities in Korea. Among these, 14,177 (30.4%) were kindergartens, 12,155 (26.1%) were schools, and 9,949 (21.3%) were industrial facilities. In February 2021, lung cancer among culinary workers in schools was first recognized as an occupational disease. Since then, the necessity of implementing health management of culinary workers and improving the cooking environment has become a pressing issue. Previous studies have identified various cooking pollutants such as particulate matter, volatile organic compounds, and aldehydes generated during the cooking process. These pollutants have been shown to significantly impact on both indoor and outdoor environments. They are initially produced in cooking spaces, can spread to indoor dining areas by diffusion, and are eventually emitted to the outside air through exhaust outlets. Therefore, this study investigated previous research on the characteristics of pollutants and the environmental impacts of cooking facilities, including facilities providing meals. Additionally, this study analyzed the current status and limitations of policies and pollutant management systems related to these facilities. Finally, to improve the cooking environment and safeguard the health of workers, this study proposed several recommendations. These include guidelines and management system proposals for controlling cooking pollutants.

In this study, hybrid devices were developed to simultaneously remove odor and particulate matter (PM) emitted during meat grilling, and their performance was evaluated. A ceramic filter system and surfactant microbubble plasma system were used to reduce particulate matter. For odor reduction, an electro-oxidation system, an ozone-active catalytic oxidation system, and a multi-adsorption filter system were used. By combining the above particulate matter reduction and odor reduction devices, the reduction efficiency of odor and particulate matter generated during meat grilling was analyzed. As a result, most of the six combined device conditions showed a reduction efficiency of more than 90% for particulate matter. The combined odor also showed a high reduction efficiency of less than 200 times the emission concentration standard. This study also evaluated 22 types of odorous substances, of which ammonia (NH3) and hydrogen sulfide (H2S) showed removal efficiencies of more than 99%. Therefore, it is expected that the combination of these technologies can be used and applied directly to the sites where meat grilling restaurants are located to effectively contribute to the simultaneous reduction of particulate matter and odor.

The main purpose of this paper is to examine the intersubjective experiences of those who use the ‘-geodeun’ construction within the Korean language. For this purpose, we consider two categories; those based on ‘modality’ and those based on ‘information structure.’ Based on consideration, two categories is not appropriate for the term ‘-geodeun’. Therefore, this paper suggests new grammatical category (intersubjectivity). Using this category, we are able to explain how ‘-geodeun’ is used in both exceptional and normal cases. Furthermore, intersubjectivity is a comparative concept and requires learners to compare the use of ‘-geodeun’ with similar constructions in their mother tongues. In the view of intersubjectivity, ‘-geodeun’ expresses speaker’s attention to listener. Speaker exposes attention to listener’s knowledge and judges whether listener knows about the information included speaker’s utterance (message). Especially, ‘-geodeun’ can be used both new and old information to listener. On based on this usage, this paper suggests models of instruction for teaching and learning intersubjectivity of ‘-geodeun’ for increasing applicability of actual education field. Introduction of concept of intersubjectivity contributes to improving Korean grammar accuracy between similar grammar item and learners’ fluency.

In South Korea, over 400,000 Non-building Structures are inadequately managed and exposed to potential risks due to insufficient inspection systems, leading to an increase in accidents and significant losses of life and property. Therefore, it is crucial for users to conduct proactive self-inspections to identify and mitigate potential hazards. This study reclassified Non-building Structures into four main categories by analyzing their structural characteristics and associated risks through statistical analysis. Among these, retaining walls, which account for the largest proportion, were systematically analyzed to identify common damage patterns. Based on this analysis, self-inspection checklists were developed for both non-experts and experts. The proposed process involves an initial visual inspection using a simple non-expert checklist, followed by a more detailed expert-level inspection if any anomalies are detected. The reliability of this process was validated through approximately 120 validation processes.

Recently, active research in Korea and worldwide has begun to focus on gene function and cultivar development using gene editing tools. This research, in addition to studies on edible mushroom, aims to enhance the physical and biochemical characteristics of mushrooms for applications in materials and substance production. For these studies, efficient isolation of protoplasts from the target mushroom is critical. However, several commercial cell wall-lysing enzyme cocktails, including Novozyme234, Glucanex, and Lysing enzymes, have recently been discontinued. In this study, we aimed to identify alternative enzyme systems to replace the discontinued cell wall-lysing enzymes for stable isolation of protoplasts from Ganoderma lucidum. To select an optimal osmotic buffer, enzyme function in 0.6 and 1.2 M Sorbitol, Sucrose, Mannitol, and KCl was assessed. The effect of reaction time was also evaluated. Protoplast isolation efficiency of each alternative enzyme was tested using lysing enzymes from Trichoderma harzianum, Chimax-N, and Yatalase, either individually or in combination. This matrix of studies identified enzymes and optimal conditions that could replace the discontinued lysing enzymes.

In modern society, buildings are becoming more complex, and the population is becoming more densely populated. Such large buildings require a variety of evacuation measures, as there is a high possibility of large-scale human casualties due to increased evacuation distance and evacuation time in the event of a fire. Strobe light and exit sign light are used as important evacuation equipment to provide early warning and evacuation directions. In this thesis, we conducted a fire simulation assuming that a fire occurrence point notification function and a strobe light function were added to equipment such as visual alarms and evacuation guidance, and compared and analyzed the difference in evacuation completion time with existing equipment. The scenarios for the simulation were divided into “general fire situations” and “fire location and evacuation exit guidance situation” and the differences in evacuation completion time in the event of a fire were compared and analyzed for each floor from the 1st floor to the 3rd floor. The maximum travel distance to complete evacuation in the case of a fire on the first floor decreased by 80.6 m and the evacuation completion time decreased by 329.4 seconds, and the maximum travel distance to complete evacuation in the case of a second-floor fire decreased by 28.5 m and the evacuation completion time by 438.8 seconds. During the fire on the third floor, the maximum distance decreased until evacuation was completed to 3.4 m, and the evacuation completion time was reduced by 355.6 seconds. It is expected that if the congestion level of evacuation routes is reduced by utilizing the congestion level of evacuation exits when fire alarm systems and evacuation equipment are activated, the evacuation completion time will be further shortened and evacuations will be carried out quickly and safely.

본고는 종교의 스포츠 수용에 관한 이론적 틀을 만들어서 앞으로 종교의 위기를 극복할 수 있는 길을 마련하는 데 목적이 있다. 스포츠와 종교 간의 긴밀한 관계는 특히 스포츠 선교가 복음 전파의 통로로서 큰 성과를 보여주고 있는 데에서도 드러난다. 스포츠가 종교를 ‘즐겁게’ 할 수 있다는 주장은 전통적인 종교의 경건성, 엄숙성이 주는 무게나 어렵고 딱딱한 분위기를 스포츠가 매력적으로 또는 즐겁게 변화시 켜 줄 수 있음을 의미한다. 스포츠의 기능 중 중요한 것이 레크리에이션이다. 서구에서 18, 19세기 산업사 회로 옮겨가면서 사회복음이 출현했는데, 특히 이 복음에는 ‘오락과 스포츠’, 바로 레크리에이션을 포함했 다. 교회 레크리에이션은 신체적, 정신적, 도덕적 가치를 지니고 있어서, 스포츠와 복음적 메시지의 결합 은 교회의 필수적인 프로그램으로 의미, 도덕 및 목적에 대한 현대의 불안을 해소하는 하나의 출구를 제공한다.
