This study considers types of expression and examines aesthetic characteristics through analyzing designs (such as the Coca-Cola contour bottle as fashion) which has actively progressed in the collaboration of fashion designers and fashion brands. The conclusions of this study are as follows. The types of fashion expression on the Coca-Cola contour bottle are a presentation of diverse fashion images through a digital print expression that allow people-friendly images to be three-dimensional (or by adding a formative element) and the use of accessories or clothes. The symbolism characteristic were first indicated for the aesthetic characteristics on the Coca-Cola contour bottle. Symbolism is indicated through the identification of an implicit meaning towards a specific object. The symbolism of fashion was highlighted by designing the Coca-Cola's contour bottle with a typical material and pattern pursued by fashion designers and fashion brands. Second, the characteristic of playfulness was presented to expresses the instinctive desire in human nature for pleasure. The expression of visual playfulness is emphasized through the combination of item and image or by changing and re-analyzing a form through refuting stereotypes. Third, the characteristic of femininity was shown to express beauty in external image or a woman's delicate and soft inner propensity. Femininity was created by presenting a sensual femininity that recognized the voluminous curve silhouette of the Coca-Cola bottle such as a sexy female body or through the combination of a women's inner beauty with the sensory image of the object.

Bezoars are collections or concretions of indigestible foreign material that accumulate and coalesce in the gastrointestinal tract; they usually occur in patients who have undergone gastric surgery and have delayed gastric emptying. Treatment options include dissolution with enzymes, endoscopic fragmentation with removal or aspiration, and surgery. Recently, the efficacy of nasogastric lavage or endoscopic infusion of Coca-Cola for the dissolution of phytobezoar have been reported. We report a case of phytobezoar successfully treated by oral administration and endoscopic injection of Coca-Cola. A 62-year-old woman was referred to Yeungnam University Hospital for epigastric pain. Upper gastrointestinal endoscopy revealed one very large, dark-greenish, solid bezoar in the stomach with gastric ulcer and duodenal bulb deformity. We performed endoscopic injection of Coca-Cola into the bezoar. The patient was instructed to drink four liters of Coca-Cola per day. At endoscopy two days later, the phytobezoar was easily broken into pieces. At endoscopy on the $11^{th}$ day of admission, the phytobezoar was decreased in size and removed by endoscopic fragmentation with a polypectomy snare. At follow up endoscopy after 13 days, the bezoar was completely dissolved.

Gastric bezoars are concretion of undigested material in the gastrointestinal tract. In the past, gastric bezoars were generally treated with surgical management. Recently, the efficacy of oral intake or endoscopic injection therapy with Coca-Cola has been reported. We report a case of a 47-year-old-man with huge gastric bezoar ($4{\times}2.5$ cm) that was successfully removed by endoscopic fragmentation with Coca-Cola injection. Compared with a single endoscopic fragmentation therapy, the combination therapy with Coca-Cola injection shortened the procedure time and reduced the complication associated with fragmented bezoar.

The purpose of this paper is to provide corpus-based quantitative analyses of HEART and HEAD in order to examine their actual usage status and to consider some cognitive linguistic aspects associated with their use. The two corpora COCA and COHA are used for analysis in this study. The analysis of COCA corpus reveals that the total frequency of HEAD is much higher than that of HEART, and that the figurative use of HEART (60%) is two times higher than its literal use (32%); by contrast, the figurative use of HEAD (41%) is a bit higher than its literal use (38%). Among all four genres, both lexemes occur most frequently in fictions and then in magazines. Over the past two centuries, the use of HEART has been steadily decreasing; by contrast, that the use of HEAD has been steadily increasing. It is assumed that the decreasing use of HEART has partially to do with the decrease in its figurative use and that the increasing use of HEAD is attributable to its diverse meanings, the increase of its lexical use, and the partial increase in its figurative use. The analysis of the collocation of verbs and adjectives preceding HEART and HEAD, as well the modifying and predicating forms of HEART and HEAD also provides some relevant information of the usage of the two lexemes. This paper showcases that the quantitative information helps understanding not only of the actual usage of the two lexemes but also of the cognitive forces working behind it.

This study examines the effects of data-driven learning (DDL)-an approach employing corpora for inductive language pattern learning-on error identification in second language (L2) writing. The data consists of error identification instances from fifty-five participants, compared across different reference materials: the Corpus of Contemporary American English (COCA), dictionaries, and no use of reference materials. There are three significant findings. First, the use of COCA effectively identified collocational and form-related errors due to inductive inference drawn from multiple example sentences. Secondly, dictionaries were beneficial for identifying lexical errors, where providing meaning information was helpful. Finally, the participants often employed a strategic approach, identifying many simple errors without reference materials. However, while maximizing error identification, this strategy also led to mislabeling correct expressions as errors. The author has concluded that the strategic selection of reference materials can significantly enhance the effectiveness of error identification in L2 writing. The use of a corpus offers advantages such as easy access to target phrases and frequency information-features especially useful given that most errors were collocational and form-related. The findings suggest that teachers should guide learners to effectively use appropriate reference materials to identify errors based on error types.

영어의 분리부정사구문을 통시적 연구인 문법화의 관점에서 중세영어이후 출현 동기를 살펴보고 COHA, COCA와 같은 코퍼스에 기반하여 주로 미국영어에 나타나는 현재영어(PDE)의 분리부정사의 정당성을 논의하는 것이 연구의 목표이다. 중세영어 이전에는 비문법적이었던 부정사 첨사인 to와 원형동사 사이에 부사 등이 위치하는 [to + 부사 + 동사] 형태의 분리부정사가 어떻게 현재영어에서는 문법적 구문이 되었는지에 대한 출현 동기와 정당성을 살펴본다. 문법화와 코퍼스의 실증적 자료에 기초하여 분리부정사구문의 문법성을 입증하고 영어 분리부정사구문의 출현에 관한 통시적 분석인 문법화 과정을 그 증거로 제시한다. 분리부정사가 왜 만들어지는가의 질문에 대한 답으로 동사이동의 소멸이라는 통시적 문법화를 들 수 있다. 코퍼스 자료에 기초한 통사·화용적인 이유는 표현의 명확성 즉, 탈중의성을 위한 것이거나 분리자인 부사를 통해 인상적인 강조를 하기 위한 것이다. 결론적으로 부사가 to와 원형동사를 분리할 것인가 말 것인가의 문제는 더 이상 문법적 논의의 대상이 아니며 앞으로도 분리부정사의 형태는 자연스러운 문법적 구문으로 문맥상 필요한 경우 더욱 증가하는 추세를 보일 것이다.

Background: Although the consumption of vitamin beverages has increased because of the recent interest in health and beauty, guidelines addressing appropriate consumption habits are lacking. Thus, the aim of this study was to investigate the erosive potential of several vitamin beverages and to propose guidelines for the appropriate intake of these drinks. Methods: Five vitamin beverages were selected after a pre-investigation of the current beverage market. Coca-Cola and mineral water were selected as the control beverages. The pH of the beverages was measured with a calibrated pH meter, and the titratable acidity (TA) was determined by using 1 M sodium hydroxide to reach pH 5.5 (TA5.5) and 7.0 (TA7.0). The screening method suggested by the International Organization for Standardization was used to measure pH variation (ΔpH) by using an under-saturated hydroxyapatite solution to determine the difference between the initial and final pH of the screening solution. All measurements were performed in triplicate. Results: All vitamin beverages tested in this study exhibited a low pH (2.53~2.99), similar to Coca-Cola, which is known to be a highly acidic beverage. The highest TA5.5 and TA7.0 values of the vitamin beverages were 7.03 ml and 8.81 ml, respectively. The largest change in pH determined by using the screening solution was found in Bacchus D (ΔpH 1.44±0.05). The mean ΔpH of the vitamin beverages was 1.12±0.29, which was higher than that of Coca-Cola (positive control, ΔpH 0.58±0.05). Conclusion: Vitamin beverages exhibited an erosive potential capable of damaging enamel surfaces. Therefore, the frequency of vitamin beverage intake should be limited, and individuals consuming these drinks should try to restore normal oral pH as quickly as possible.

Objectives: The aim of this study was to evaluate the effect of three different drinks on the color parameters of four different restorative materials. Materials and Methods: Three different composites (Filtek Ultimate Universal Restorative, Filtek Ultimate Flowable, and Filtek Silorane, 3M ESPE) and a polyacid-modified composite resin material (Dyract XP, Dentsply DeTrey GmbH) were evaluated. Eighty-four disc-shaped specimens of 8 mm in diameter and 2 mm in thickness were prepared (n = 21 each). Color coordinates ($L^*a^*b^*$, ${\Delta}L^*$, ${\Delta}a^*$, ${\Delta}b^*$, and ${\Delta}E^*$) were measured using a $V{\dot{I}}TA$ Easyshade Compact ($V{\dot{I}}TA$ Zahnfabrik) after 24 hr of storage (baseline) and after 30 day of storage in three different beverages of black tea, Coca cola, or water (control) (n = 7). In each beverage, the specimens were stored three times a day, one hr each, for 30 day. The color changes (${\Delta}E$) were calculated and were analyzed by Kruskal-Wallis and Dunn multiple comparison test. Results: The color difference (${\Delta}E^*$) of the resin materials ranged between 1.31 and 15.28 after 30 day of immersion in the staining solutions. Dyract XP in Coca cola ($15.28{\pm}2.61$) and black tea ($12.22{\pm}2.73$) showed the highest mean ${\Delta}E^*$ value after 30 day, followed by Filtek Ultimate Universal Restorative ($5.99{\pm}1.25$) and Filtek Ultimate Flowable ($4.71{\pm}1.40$) in black tea (p < 0.05). Conclusions: The compomers displayed unacceptable color changes at the end of 30 day in all beverages. Among resin composites, the silorane based composite exhibited relatively good color stability than the others. Filtek Ultimate Universal Restorative and Filtek Flowable showed similar color changes in all beverages.
