In programming classes, there is always a need to efficiently manage programming assignments. This is especially important as class sizes and assignment complexity grows. GitHub and GitHub Classroom makes the management of student assignments much simpler than uploading files and folders to a LMS or shared online drive. Additionally, git and GitHub are industry standard tools, so introducing students these tools in class provides them a good opportunity to start learning about how software is developed in the real-world. This study describes a workflow that uses both GitHub Pages and GitHub Classroom for more efficient classroom and assignment management. The workflow outlined in this study was used in two practical web programming classes in Spring 2023 with 46 third and fourth-year university students. GitHub Pages was used as a classroom website to distribute class announcements, assignments, lecture slides, study guides, and exams. GitHub Classroom was used as a class roster and assignment management platform. The workflow presented in this study is expected to assist other lecturers with the formidable tasks of distributing, collecting, grading, and leaving feedback on multiple students' multi-file programming assignments in practical programming classes.

git에 대한 관심이 증가하고 있는 요즘 각종 업계에서 Version Control System을 사용하는 인원들은 git을 svn보다 복잡하다고 생각한다. 물론, 전문적인 소프트웨어 개발자라면 컴퓨터 시스템에 대한 이해가 높기 때문에 이에 별로 구애받지 않을 수도 있다. 하지만, 그 외 디자이너, 학생과 같이 전문 개발자가 아닌 인원들은 git을 이해하기 어려워하고 있다. git을 처음 접하는 인원들이 어려움을 느끼는 이유는 개념의 이해와 명령어 사용이었는데, 이들에게 git 사용을 보다 편안하게하기 위한 git GUI tool 개발을 위한 모델을 제안을 한다.

One challenge with teaching practical programming classes is the standardization of development tools on student computers. This is particularly true when a complicated setup process is required before beginning to code, or in remote classes, such as those necessitated by the COVID-19 pandemic, where the instructor cannot provide individual troubleshooting assistance. In such cases, students who encounter problems during the setup process may give up on the class altogether before even beginning to code. Therefore, this paper recommends using GitHub Codespaces as a tool for implementing standardized student development environments from day one. Codespaces provides Docker containers that an instructor can configure in such a way as to enable students to practice installing various coding tools within a controlled space, while also providing a language-specific, fully optimized development environment. In addition, Codespaces may be used more effectively in collaboration with GitHub Classroom, which helps instructors manage both the starter code and coding environment in which students work. In this paper, we compare two semesters of university Node.JS programming classes that utilized different development environments: one localized on student computers, the other containerized in Codespaces online. Then, we discuss how GitHub Codespaces and GitHub Classroom can be used to increase the effectiveness of practical programming classes while also increasing student engagement and programming confidence in class.

Enteropathogenic Escherichia coli (EPEC) is a major cause of infantile diarrhea in developing countries. However, sporadic outbreaks caused by this microorganism in developed countries are frequently reported recently. As an important zoonotic pathogen, EPEC is being monitored annually in several countries. Hallmark of EPEC infection is formation of attaching and effacing (A/E) lesions on the small intestine. To establish A/E lesions during a gastrointestinal tract (GIT) infeciton, EPEC must thrive in diverse GIT environments. A variety of stress responses by EPEC have been reported. These responses play significant roles in helping E. coli pass through GIT environments and establishing E. coli infection. Stringent response is one of those responses. It is mediated by guanosine tetraphosphate. Interestingly, previous studies have demonstrated that stringent response is a universal virulence regulatory mechanism present in many bacterial pathogens including EPEC. However, biological signficance of a bacterial stringent response in both EPEC and its interaction with the host during a GIT infection is unclear. It needs to be elucidated to broaden our insight to EPEC pathogenesis. In this review, diverse responses, including stringent response, of EPEC during a GIT infection are discussed to provide a new insight into EPEC pathophysiology in the GIT.

This study is about single-layered $Chog{\breve{a}}ri$ excavated from SongHyosang(宋效商, 1430-1490, SHS hereafter), SongHeeJong(宋喜從, the late 1500s, SHJ hereafter) tombs. There are 7 single-layered $Chog{\breve{a}}ris$ for men. We focus on comparison of their design and sowing method. 1. Design: Investigating collar, $Chog{\breve{a}}ris$ from SHS have MokpanGit and $Chog{\breve{a}}ris$ from SHJ have KalGit. KalGit has been seen from SHJ to 17th, 18th and 19th centuries. After the late 1500s, there is no MokpanGit single-laTered $Chog{\breve{a}}ri$ for men. Side panel under arm has various shapes(triangle, trapezoid, triangle+trapezoid) in 15th century. After the late 1500s, It changes into no side panel. Two $Chog{\breve{a}}ris$ with no side panel from SHJ reveals that the late 1500s is a period of transition. 2. Sewing method: First, researching lengthwise grainline of the fly, the left fly has lengthwise grainline outside In four, inside in three. The right fly has lengthwise grainline outside in just one, the others have lengthwise grainline inside. Compared with today's way, there is a great difference, but in those times there isn't an established rule. This is true of side panel under arm. The sewing method are backstitch, running stitch, and hemming. Researching the construction method of seam, in putting two selvages together, open seam and plain seam are used. In putting selvage and bias, bias and bias together, flat felled seam and french seam are used. This study shows that single-layered $Chog{\breve{a}}ri$ far men from 15C. to 16C. has changes of design such as collar(Git) and side panel undo. arm. But there is little change in sewing method.

Purpose: This study was designed to investigate the effects of Gaeullijin-Tang(GIT) on the progression of the estradiol valerate(EV)-induced polycystic ovaries(PCO) in rats. Methods: PCO was induced by single intramuscular injection with estradiol valerate(EV)(4mg) in female rats. Normal group(n=8) were injected with sesame oil and orally administrated distilled water for sixty days. PCO control group (n=8) were injected with EV and orally administrated distilled water for sixty days. GIT treated group(n=8) were injected with EV and orally administrated GIT for same duration. At the end day of experiment, we measured weights of body, ovaries, adrenal glands, uterus and contents of serum androsternedione (ADD) and total estrogen. The histomorphometrical changes of ovaries were also evaluated. And we observed the NGF and CRF expression by immunohistochemistry. Results: The results were as follows - The weights(mg) of ovaries in GIT treated group($75.5{\pm}4.3$) were significantly increased(p<0.001) compared with PCO control group($54.3{\pm}4.5$). - The numbers of mature follicles in GIT treated group($5.3{\pm}1.2$) were significantly increased(p<0.05) compared with PCO control group($3.5{\pm}1.2$). - The numbers of corpora lutea in GIT treated group($1.8{\pm}1.3$) were significantly increased(p<0.05) compared with PCO control group($0.3{\pm}0.7$). Conclusion: From the above results, we concluded that Gaeullijin-Tang(GIT) contributes to stimulating normally ovulation by decreasesing ovarian NGF concentrations.

ADHD (Attention Deficit/Hyperactivity Disorder)은 4-17세의 아동 및 청소년의 약 10%가 겪는 흔한 신경 발달 장애이지만 그 핵심 기전이 알려져 있지 않은 가운데 관련한 여러 단백질들이 보고되어왔다. 이중 GIT1 (G-protein coupled-receptor kinase interacting protein-1)은 중추신경계에서 dendritic spine formation와 growth에 영향을 미치는 multifunctional adaptor protein으로, GIT1이 제거된 생쥐는 과잉행동, 주의력결핍 그리고 충동성을 보이는 ADHD 증상을 보이게 된다. 이 논문에서는 GIT1 유전자 변형 생쥐를 이용하여 genotype별로 신경교세포의 전달물질(gliotransmitter)을 비교 분석하는 실험을 진행하였다. 그 결과 주요 흥분성 전달물질인 glutamate는 HE (hetero)와 KO (knock-out)의 세포 내에서 WT (wildtype)보다 더 높은 농도로 존재했다. 한편, 억제성 신경전달물질인 GABA와 glycine의 경우 전반적으로 HE에서 가장 많은 함유량을 보였지만 소뇌 세포내의 경우, KO이 WT보다 많은 양을 함유한 것에 비해 대뇌 세포 내에서는 KO보다 WT의 억제성 전달물질 함유량이 높았다. 또한, glutamate와 GABA를 기준으로 흥분성/억제성 비율(excitation/inhibition ratio)을 보았을 때, 소뇌 세포 내/외 모두에서 KO이 가장 높은 수치를 보였고, 대뇌에서는 세포 내/외 모두 HE에서 가장 높은 수치를 보였다. 억제성 신경전달물질인 GABA가 KO의 대뇌 세포 외에서 가장 많은 것으로 보아 GIT1 결손을 보완하기 위해 억제성 물질을 더 많이 분비하거나 또는 과도하게 분비된 GABA를 재흡수하지 못하는 것이라 사료된다. 이는 ADHD 병리기전으로써 기능할 가능성을 제시하며 후속 연구를 통해 해당 기전에 대한 규명이 필요할 것으로 보인다.

Attention deficit/hyperactivity disorder (ADHD) is one of the most common neurodevelopmental disorders, affecting approximately 5% of children. However, the neural mechanisms underlying its development and treatment are yet to be elucidated. In this study, we report that an ADHD mouse model, which harbors a deletion in the Git1 locus, exhibits severe astrocytosis in the globus pallidus (GP) and thalamic reticular nucleus (TRN), which send modulatory GABAergic inputs to the thalamus. A moderate level of astrocytosis was displayed in other regions of the basal ganglia pathway, including the ventrobasal thalamus and cortex, but not in other brain regions, such as the caudate putamen, basolateral amygdala, and hippocampal CA1. This basal ganglia circuit-selective astrocytosis was detected in both in adult (2-3 months old) and juvenile (4 weeks old) $Git1^{\check{s}/\check{s}}$ mice, suggesting a developmental origin. Astrocytes play an active role in the developing synaptic circuit; therefore, we performed an immunohistochemical analysis of synaptic markers. We detected increased and decreased levels of GABA and parvalbumin (PV), respectively, in the GP. This suggests that astrocytosis may alter synaptic transmission in the basal ganglia. Intriguingly, increased GABA expression colocalized with the astrocyte marker, GFAP, indicative of an astrocytic origin. Collectively, these results suggest that defects in basal ganglia circuitry, leading to impaired inhibitory modulation of the thalamus, are neural correlates for the ADHD-associated behavioral manifestations in $Git1^{\check{s}/\check{s}}$ mice.

Git의 커밋 메시지는 프로젝트가 진행되면서 발생하는 각종 이슈 및 코드의 변경이력을 저장하고 관리하고 있기 때문에 소프트웨어 유지관리와 프로젝트의 생명주기와 밀접한 연관성을 갖고 있다. 이러한 Git의 커밋 메시지에 대한 정확한 분석 결과는 소프트웨어 개발 및 유지관리 활동 시, 시간과 비용의 효율적인 관리에 많은 영향을 끼치고 있다. 이에 대한 기존 연구로 Git에서 발생하는 커밋 메시지를 소프트웨어 유지관리의 세 가지 형태로 분류하고 매핑하여 정확한 분석을 시도하려는 연구가 진행되었으나, 최대 87%의 정확도를 제시한 연구 결과가 있었다. 이러한 연구들은 정확도가 낮아 실제 프로젝트의 개발 및 유지관리에 적용하기에는 위험성과 어려움이 있는 현실이다. 본 논문에서는 커밋 메시지 분류에 대한 선행 연구 조사를 통해 각 연구들의 프로세스와 특징을 추출하였고, 이를 이용한 분류 정확도를 높일 수 있는 커밋 복합 분류 모델에 대해 제안한다.
