Mucoepidermoid carcinoma (MEC) is the most prevalent malignant tumor originating from the salivary gland. The gradation of MEC is determined histologically based on cellular composition, with high-grade MEC presenting with distinct characteristics and clinical implications. A 56-year-old male presented with a 3-month history of right facial swelling and a recent onset of pain. A subsequent biopsy confirmed a malignant epithelial tumor, with further imaging assisting in determining the surgical approach. Comprehensive surgery, involving the removal of the right submandibular gland and reconstructive procedures, was undertaken. Histopathological evaluation post-surgery confirmed a high-grade MEC. The differentiation between inflammatory conditions and neoplastic lesions in the orofacial region can be challenging. The gradation of MEC is important in guiding therapeutic decisions. Among various classification systems, the Brandwein system offers detailed histopathological criteria that correlate reliably with clinical features. High-grade MECs, although less frequent, are aggressive and have a lower 5-year survival rate. Accurate histopathological diagnosis is crucial in devising an effective treatment plan. The presented case underlines the importance of a meticulous yet periodic follow-up, considering the aggressive nature of high-grade MECs.

Industrial complexes are areas where manufacturing companies are integrated, and logistics between tenant companies play a very important role, but idle resources can occur depending on the situation if each company operates independently. Accordingly, this study aimed to reduce overall logistics costs and increase corporate productivity by looking at ways to share and utilize logistics resources such as warehouses and transportation equipment to efficiently utilize logistics resources in industrial complexes and implementing a logistics sharing platform that can share these idle resources. To this end, this study conducted a research survey on the logistics status of manufacturing companies in Ulsan-Mipo Industrial Complex, based on this analysis, the necessity of logistics resource types and utilization of industrial complex resident companies, and based on this, a service model for logistics resource sharing was studied. In addition, it was intended to analyze the operational characteristics of the existing logistics system to derive improvements and to derive optimal measures to utilize information on shared idle resources. This study confirmed the importance of sharing and utilizing idle resources to optimize logistics resources in industrial complexes, and is expected to contribute to reducing logistics costs and increasing logistics efficiency of tenant companies.

본 연구는 영화 <헤어질 결심>을 중심으로 영화 속 색상의 상징적 의 미와 감독의 제작 스타일을 탐구하여 영화 속에서 색상이 얼마나 중요한 지를 이해하고, 감독이 색상을 통해 주제를 어떻게 전달하는지를 보여주 고자 한다. 본 연구는 움베르토 에코 기호학을 바탕으로 색상의 보편적 인 상징성과 결합하여 ‘표현-내용-해석체’의 삼원론적 기호 관계를 분석 방법으로 사용하고, 추측 방법을 통해 색상 기호 의미의 생산 과정을 설 명하고 영화 속 색상의 다양한 표현 방식이 상징하는 의미를 심도 있게 발굴하였다. 또한, ‘기호 활동’의 반복 이론을 통해 서로 다른 색상의 반 복적인 등장을 분석하여 색상과 영화 주제와의 연관성을 설명하였다. 본 연구를 통해 박찬욱 감독이 독창적인 색상 활용을 영화의 디테일한 부분 과 잘 접목시켜 영화 표현 형식의 다양화와 주제 강화를 실현하고, 관객 의 감성적 참여를 높인다는 것을 알 수 있다. 색상은 긴장감이 넘치는 분위기를 조성할 뿐만 아니라 인물에게 신비한 매력을 부여해 전반적인 스토리에 예술적 요소를 더한다. 본 연구는 영화 속 색상 활용에 따른 기호학 분석에 새로운 아이디어와 방법을 제시하고, 영화 제작에 이론적 인 참고 자료를 제공하고자 한다. 향후 연구에서는 더 많은 기호학 이론 을 활용해 연구 범위를 확대하고, 영화 색상 활용에 대한 인식을 풍부하 게 하여 영화 예술 발전을 더욱 촉진할 수 있을 것이다.

전 세계 대부분의 국가들은 탄소배출량을 줄이기 위한 노력을 지속하고 있다. RC구조물의 탄소배출량을 줄이기 위해 수십 년간 건설 분야의 많은 연구자들이 철근콘크리트 구조물에서 철근을 FRP보강근으로 대체하기 위한 연구를 수행하여 왔다. 북미지역을 비롯한 일부 지역에서는 해양구조물이나 도로 등에 CFRP보강근을 사용한 바 있다. 그러나 건축물에는 철근을 CFRP보강근으로 대체한 사례와 적용을 위한 연구는 거의 진행되지 않았다. 따라서 본 연구에서는 예제건물을 선정하여 철근콘 크리트구조로 설계한 후, 철근을 CFRP보강근으로 대체하여 설계함으로써, 철근콘크리트건물에서 철근을 CFRP보강근으로 대체 하였을 때 철근량을 비교하였다. 그 결과 슬래브의 철근비가 0.005미만으로서 CFRP의 사용량을 줄일 수 있을 뿐만 아니라 안전 율 측에서도 우수한 것으로 나타났다.

The Lepidoptera - moths, butterflies, and skippers, is one of the three most species-rich, studied, diverse, and widely distributed insect orders, with over 157,424 species worldwide (van Nieukerken et al., 2011). Moths and butterflies serve as valuable indicator species for monitoring climate change. Conversely, the distribution of lepidoptera is actively and interactively influenced by changes in climate and land cover (Warren et al., 2001). Over the last five years, there are many oriental moth species, such as genus Stictane, Siccia, Philenora, Ammatho, Asota, etc., have been newly recorded in Korea, since other new records are very likely yet to be discovered in this country and nearby.

Since the importance of integrated pest management to minimize environmental damage and maximize pest control effectiveness has emerged, efforts to put it into practice have continued. To implement IPM, it is necessary to estimate the economic injury level to determine the control method by identifying pests and weeds that damage the quantity and quality of crops in the field, investigating the occurrence level, and calculating the ratio of cost and effectiveness. Also, damage to host plants caused by increased density of insect pests appears to change plant’s health that key factor for managing crops. Therefore, understanding the relationship between the density of pests and the damage to the host plants is necessary. This study aims to analyze the causal relationship between the density of insect pests and damage to the host plants for estimating the economic injury level of insect pests on the host plants and investigating the possibility of pest control decision-making using plant health status.

This qualitative case study explores multilingual learners’ linguistic practices and how they are interrelated with their identities in the context of a Korean alternative school. The learners are two Chosunjok, and one North Korean refugee child. The data were derived from the learners’ digital storytelling videos, semi-structured interviews, stimulated-recall interviews, and observation field notes. The data were thematically analyzed and organized using Rose’s (2007) sites of visual meaning-making structure. The findings revealed that the learners had different amounts of access to information regarding second language learning, and that they depended on the resources available within the communities they belonged to. Moreover, the participants’ levels of investment in language learning were constructed around their communities and identities. Their attitudes in language learning were also interrelated with the broader English language ideologies in South Korea. By sharing the stories of three multilingual learners, the study provides pedagogical implications on the influence of resources on multilingual learners’ language learning. We emphasize the importance of providing a space for multilingual learners to critically reflect on current and future resources, utilize their full communicative repertoire, and identify ways to increase their affordances of learning.

A 11 year-old, female, shih-tzu mixed-breed dog was presents with history of sudden blindness for 2 days. An ophthalmic test was conducted to find the cause of blindness, including an intraocular pressure test, a fundus test, and an electroretinogram. As a result of the test, the abnormality in the eye could not be confirmed, so MRI request was made. MRI confirmed mass areas with 1.0 × 0.5 mm T2W/FLAIR heterogeneous hyperintense, T1W isointense, and enhancement that spread widely from the dorsal part of the sella turcica to the anterior optical chiasm. Cystic lesion was identified in the front of the lesion, and it had the characteristics of an extra-axial tumor such as a broad base attachment surface and a dural tail signal. Based on these tests diagnosed blindness caused by brain tumors. Clinical symptoms began to improve three days after taking chemotherapy, and all clinical symptoms disappeared after a week. This case report demonstrated that clinical sign, diagnostic imaging and successful treatment result with chemotherapy in canine brain tumor patient.

Mucosa-associated lymphoid tissue (MALT) lymphoma (ML) is a type of non-Hodgkin’s lymphoma involving MALT, commonly the stomach or salivary glands, although virtually any mucosal site can be affected. ML originates from B cells in the marginal zone of MALT, and is also called extranodal marginal zone B cell lymphoma. It is a slow-growing cancer that usually responds well to treatment. A 59-year-old female presented with a 1-day history of quadriparesis and dysarthria. Up arrival at the hospital, motor power in the right upper and lower extremities was grade 3/5 according to the Medical Research Council scale, while that in the left leg was 4/5. The patient had been diagnosed with gastric ML 1 year prior, and had received antibiotics during the previous 2 weeks. The emergency magnetic resonance imaging of the brain performed at the time of presentation showed multifocal embolic infarction in the cerebral hemisphere bilaterally, which did not have a cardiac origin. Magnetic resonance angiography revealed no stenotic or occlusive lesions. Secondary prophylaxis with daily administration of 300 mg aspirin was prescribed. The patient was discharged with residual right hemiparesis 2 weeks after the onset of symptoms. Herein, we present a rare case of multifocal cerebral infarction in a gastric ML patient.
