As public awareness of global warming increases, the construction industry requires more knowledge than ever about environmental issues. Now a new generation of scientists, architects, and engineers are radically rethinking how we build. In recent years, the issue of public toilets has developed from an inconvenient subject into one that attracts great attention. However, the effort to make them more sustainable is still insignificant compared with that of other types of buildings. The purpose of this paper is to analyze the problems of public toilets and green building certification programs, to draw basic data through the use of a survey and to facilitate the utilization of appropriate sustainable design elements to create environmentally responsible public toilets. There was no specific guideline for the green public toilet, so the sustainable design elements were set based on the national green building certification program. However the crucial factors in the survey differed from what was considered important in the program such as energy, water resource and interior environment.

본 연구에서는 전자산업폐수에 함유되어 있는 불소성분을 제거하기 위하여 미세 침강성 석회석을 적용해보고자 하였다. 석회석의 입자크기는 평균 0.96 μm이었으며, 질량 기준으로 70%가 함유된 수용액상의 pH는 10이었다. 현탁액의 침강속도는 2 mL/hr로 나타났다. 본 연구의 시험용 석회석 수용액은 폐수 중화와 불소이온 제거능력 면에서 기존의 액상소석회와 동등 이상의 성능을 보여주었다. 추가적인 알칼리 증량제의 투입양에 따라 pH 7에 도달할 수 있는 시험용 칼슘원의 양은 기존의 석회수보다 적었다. 또한 불화수소로 고정시킬 수 있는 양도 미분말 석회석이 석회수보다 큰 것으로 나타났다. 또한, Minteq 평형모델링으로부터 다양한 불소와 칼슘화합물 형성이 예상되었다. This study attempted to utilize ultrafine precipitated calcium carbonate for fluoride removal from the wastewater of electronics industries. An average particle size of the calcium carbonate was 0.96 μm, and pH of the aqueous slurry was 10 with 70% in mass. The suspension solution showed approximately 2 mL/hr of the sedimentation rate. The present calcium carbonate solution could be comparable to the conventional aqueous calcium source, Ca(OH)<sub>2</sub>, for the neutralization and removal of fluoride ions. Depending on the amount of an additional alkali source, less amounts of test Ca-source slurries were required to reach the solution pH of 7.0 than that of using the aqueous calcium hydroxide. It was also found from XRD analysis that more calcium fluoride precipitates were formed by the addition of calcium carbonate solution rather than that of calcium hydroxide. In addition, Minteq equilibrium modelling estimated various ion complexes of fluoride and calcium in this process.
양태를 나타내는 조동사 「そうだ」와 접미사 「げ」의 의미ㆍ용법

本稿では様態を表す助動詞「そうだ」と接尾辞「げ」の用例において頻度数が異なっている前接項目を分析することで両者の意味ㆍ用法の相違点を観察することを目的とする。その結果、「そうだ」は与えられた状況に基づいて話者が対象の感情ㆍ属性を判断或は予想する用法として使われており、「げ」は対象の外見に注目し、対象の状態を強調する用法として使われていることが分かった。また、語彙の特性とともに話者が対象の状態をどのように捉えたかにより「そうだ」と「げ」の選択が決まるということも確認できた。 ただし、いずれの方に頻度数が偏重している用例のうち頻度が0ではなく極少数の例が発見される語基においては、単に話者が対象の状態をどのように捉えたかについての分析だけでなく、「そうだ」と「げ」の意味領域がどういう風に変化しているかに関して更なる認知学的な考察が必要であろうと思われる。更に、容認度の観点からすると、「そうだ」にも慣用的な結合が存在する可能性が見つかったため、インターネット空間といった異なる母集団においてもこのような用例は存在するのかを検討する必要があると思われる。 In this article, we note that the frequency of elements to which the manner auxiliary verb souda is attached and that to which the suffix ge is attached differ in attested examples, and observe differences in meaning and usage between the two expressions. Our finding is that souda is used when the speaker judges or expects the emotion/property of the object, while ge is used when the speaker notes the appearance of the object and emphasizes the state of the object. Furthermore, we observe that the selection of either souda or ge depends on their lexical properties and how the speaker construes the state of the object. The lexical bases whose frequencies are radically low, however, would require a cognitive linguistic consideration of how the speaker construes the state of the object and how the semantic domain of souda and that of ge have shifted. Furthermore, from the viewpoint of acceptability, because there is a possibility that a idiomatic combination exists also in souda, it seems that there are other examples such as this, and also in other populations such as internet space. It is thought that it is necessary to investigate whether the examples can be found.

Due to recent industrialization and increasing population, there has been increase in number of accident, which has subsequently led to increase in trauma patients. Blunt abdominal trauma is a supreme challenge to the emergency specialist`s clinical acumen. Historical data may be incomplete, absent, or presumptive. The symptoms and signs can be unreliable and obfuscated by head injury, alcohol, or depressed mental status(1). Although abdominal trauma is common, diagnosis and treatment has always been difficult due to the complex structure of abdomen, despite advance in diagnostic technique. If the patient show peritoneal irritation sign or hemodynamic instability immediately after abdominal trauma, there is need for open surgery to diagnose and to treat peritonitis and hemoperitoneum. However, it is known that patient may show no symptom or sign immediately but may result in delayed bowel perforation which could be fatal for the patient. Therefore we reported a case of peritonitis due to delayed bowel perforation 7 days after abdominal trauma.
내시경적 Unroofing 방법으로 진단한 직장 Mucosa-associated Lymphoid Tissue 림프종

Mucosa-associated lymphoid tissue (MALT) lymphoma is a typical primary gastrointestinal lymphoma, particularly in the stomach. Although primary rectal lymphoma is rare, it may present as a subepithelial tumor. Several techniques have been proposed for a tissue diagnosis in subepithelial tumor, including endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA), EUS-guided trucut biopsy (EUS-TCB), and tacked biopsy. However the diagnostic efficacy of these techniques appears to be limited. The unroofing technique involves removal of the overlying mucosa, thereby exposing the subepithelial lesion. It was originally reported as a method for endoscopic treatment of colorectal lymphangioma. In this case, a subepithelial tumor of the rectum was diagnosed using the endoscopic unroofing technique. This is a useful modality for the diagnosis of subepithelial tumor, because it provides histologic results in a safe and rapid manner. (Korean J Gastroenterol 2012;59:428-432)
