A 7-year-old boy, diagnosed with an arachnoid cyst and subdural effusion on initial MRI, was admitted with left limb weakness and no history of head trauma. A subsequent follow-up MRI showed different stages of hematoma within multilayered enhancing membranes and in the arachnoid cyst, which was separated by the cerebrospinal fluid cleft. Craniotomy and fenestration of the cyst wall and hematoma removal were performed. The patient was diagnosed as a having a hemorrhagic rupture of an arachnoid cyst into the intradural space, probably via some one-way valve-like defect, based on the MRI and surgical findings. The MRI features and possible mechanism of this rare disease are discussed within the literature review.

The purpose of this research is to develop more effective and systematic courage-related education in the early childhood education field. Through the previous research and literature review, the concept of courage was redefined and the type of courage was derived. After choosing 25 pictures books which relate to courage, we analyzed using the type of courage and their features. The results were as follows. First, courage is an act of trying voluntarily and continuously according to established clear goals based on personal beliefs in order to overcome inner and external difficulties. Second, we divided the courage into five types - Physical Courage, Challenge Courage, Belief Courage, Social Courage, Creative Courage- and presented each characteristic. Finally, by analyzing 25 picture books on the theme of courage according to these types and characteristics, it was confirmed that these picture books can be an important basis for courage-related education and development of a courage scale.

Adenoid cystic carcinoma (ACC) of the sublingual gland is an extremely rare neoplasm. The clinicopathological characteristics of ACC are slow-growing swelling with or without ulceration, perineural spread, local recurrence, and distant metastasis. This report describes a 58-year-old male who had a slowly growing swelling without ulceration on the right side of the mouth floor that had been present for 1 month. In a radiological examination, the mass showed multilocular cystic features and no bony or tongue muscle invasion. No enlarged cervical lymph nodes were detected. Excisional biopsy and histological analysis showed that the lesion was ACC. In addition to reporting a rare case of ACC, this report also discusses the differential diagnosis and treatment of ACC with a review of the relevant literature.

We experienced a case of well-differentiated acinic cell carcinoma of the parotid gland in a 65 year-old woman, which was correctly diagnosed preoperatively by fine needle aspiration(FNA) cytology. FNA cytology smears showed clusters or sheets of monomorphic acinic cells having reticulated or finely vacuolated basophilic or acidophilic cytoplasm. The cellular population was homogeneous or slightly polymorphic, having centrally located, round nuclei with finely reticular chromatin and inconspicuous nucleoli. Herein we report this case with its histologic features and review of literatures.

The purpose of this study is to develop the air-conditioning unit combined with the lighting unit for workspace and to supply its performance data at architectural design stage. The air-conditioning unit is one of the components of a workspace integrated unit, which can be defined as the planning unit satisfying the environmental comfort criteria of workspace. Air-conditioning diffusers are classified according to throws and features by literature review and case study. Then diffusers are combined with the lighting unit. Through the CFD simulation, the thermal performance of each unit was evaluated and finally various air-conditioning units combined with the lighting units were developed.

The epithelial-mesenchymal transition (EMT) is one mechanism by which cells with mesenchymal features can be generated and is a fundamental event in morphogenesis. Recently, invasion and metastasis of cancer cells from the primary tumor are now thought to be initiated by the developmental process termed the EMT, whereby epithelial cells lose cell polarity and cell-cell interactions, and gain mesenchymal phenotypes with increased migratory and invasive properties. The EMT is believed to be an important step in metastasis and is implicated in cancer progression, although the influence of the EMT in clinical specimens has been debated. This review presents the recent results of two cell surface proteins, the functions and underlying mechanisms of which have recently begun to be demonstrated, as novel regulators of the molecular networks that induce the EMT and cancer progression.

Increasing demand in developing countries for animal sources of food including red meat is predicted to double by 2050. In Indonesia, there has always been a gap between supply and demand of beef with national beef production only satisfying about 45% of demand. This paper aims to describe the current features and prospects for beef production systems in Indonesia. The first part of the article reviews and analyses Indonesian beef cattle production systems. The second part addresses issues related to the current systems for beef production that could become important for future development of the beef industry in Indonesia. Recommendations to improve breeding and reproduction, to empower smallholder farmers, to improve the capacity of industry-related institutions to enhance technology transfer, and to develop systems for industry development such as integration of palm oil or plantations with beef cattle production are briefly discussed.
