This study investigates why Korean English speakers misunderstand the English article system, which article Korean EFL learners use more accurately in their English writings, and implications for English writing instruction from Korean EFL learners' utterances. There have been numerous studies on the acquisition of English article system by non-native English speakers. Those studies agree that acquiring English articles is difficult for learners of English as a second language. As a result, in this study, many English learners use the definite and indefinite articles a/an. Many wrote articles from their writings, and occasionally, errors of excessive use of definite articles occurred. Through this, this paper investigates how a Korean English learner whose native language has no articles chooses the English article system in speech. It is based on the elicited production of the Korean English learner and suggests some implications for teaching English writing in the classroom. When English instructors teach Korean English learners to write English, it is more important than anything else to practice the correct usage of definite articles or indefinite articles.

English article has been considered as one of the most difficult areas to learn among ESL/EFL students. The current paper reviews English learners' article error patterns as well as pedagogy in order to teach English articles and to minimize learning difficulties on English articles. Different pedagogy for English articles on the basis of learners' proficiency levels are suggested as each proficiency level student shows a different error tendency; beginning level language learners used the zero article with the most facility while intermediate level language learners used the definite article the most accurately. However, studies about high advanced level learners' error patterns present that these high accuracy rates among beginning level students might be a result of students' plain guessing. Considering these error patterns, pedagogy for advanced level is also suggested.

The retroactive insurance is the system that the Assured, the principal of insurance contract shall be entitled to recover for insured(beneficiary in insurance of persons) loss during the period of insurance covered by this insurance, not withstanding that the loss had occurred before the contract of insurance concluded. The retroactive insurance is applicable to both property insurance and insurance of persons. The commercial law of Korea stipulates its rules in the insurance volume. The ultimate and definite articles of cargo insurance about the retroactive insurance are stipulated in MIA and ICC. In general insurance of persons stipulates relevant articles in the clause. Even though articles pertinent to the retroactive insurance are written explicitly in relevant law, it is difficult to settle the claim just by using specified rules of related regulations. Therefore, a claim is settled down based on the actual facts. After studying some of the actual dispute facts connected with the retroactive insurance having properties mentioned, this paper suggests controversial points and alternative ideas.

The articles on building height limitation are very important to form buildings to be. The application of the articles is based on the surface of the building site ground, that is, the definite judgment of ground level should ensure the correctness of building height limitation. This study surveyed the recognition degree of practitioners about the building height limitation regulations by questionnaires, and analyzed its results and compared them to related building laws and letter of reply from the office to practitioners' inquiry on related regulation. The study summarized the results as follows; 1. It is not clear to judge the ground level. Especially in cases of pilotis structure, there would be various interpretations to define its ground level. 2. According to present building regulations, the site would be confused to define by practitioners whether it is stiff or plain. 3. In case of regulation of a right to enjoy sunshine, it is hard to calculate the average horizontal level(ground level) with neighboring sites. 4. If there were a manual with illustrations for judging and calculating the ground level of various cases, civil petitions would be reduced.

Recently much research has investigated the role of attention in L2 learning, comparing the effects of explicit learning with those of implicit learning. With this background the research aims at examining the effects explicit focus on form has on L2 learning based on the acquisition of the English article system. The participants were 70 Korean college students who enrolled in English Composition classes. The experimental group received explicit focus on form including grammatical explanation, input enhancement, output practice, and negative evidence (corrective feedback) for two weeks, while the control group was exposed to sufficient input and negative evidence. Completion tasks were administered at the beginning and the end of the semester. In addition, errors in the use of English articles were analysed on their compositions both before and after the different treatments. The analyses of the results show that the explicit focus on form group improved significantly more than the control group, particularly for the definite article 'the', and some changes occurred in the distribution of article errors. These findings suggest that explicit teaching plays a more contributory role than implicit teaching in acquiring L2 knowledge in classroom-based L2 learning.

Background : It was not enough to apply three kinds of syndrome differentiation in our oriental medical textbook to tremor's treatment according to reports of Korea and traditional medical textbook of China. Objective : To investigate syndrome differentiations by types of diseases related to tremor through Chinese journals review and to suggest adding possible syndrome differentiations. Methods : Literature search was performed using China Academic Journal (CAJ), the search engine of China National Knowledge Infrastructure (CNKI) from January 1994 to December 2009. Searching key words were Chinese characters in combination meaning tremor, paralysis agitans, and syndrome differentiation. We included all types of articles that explained or referred to definite syndrome differentiations. The symptoms and oriental medications by syndrome differentiation in selected articles were extracted and summarized. Results : 56 Chinese journals were ultimately selected. 37 kinds of syndrome differentiations about tremor were investigated, which included dual deficiency of qi and blood (氣血兩虛) quoted 31 times, liver-kidney yin deficiency (肝腎陰虧) 23 times, liver-kidney deficiency (肝腎不足) 21 times, and phlegm-heat stirring wind (痰熱動風) 20 times. 37 kinds of syndrome differentiation could by group into eight types, such as liver-kidney yin deficiency (肝腎陰虧), dual deficiency of qi and blood (氣血兩虛), phlegm-heat stirring wind (痰熱動風), heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風). Conclusion : We suggest that the syndrome differentiations of tremor, such as heart deficiency and spirit weakness (心虛神弱), blood stasis due to qi stagnation (氣滯血瘀), sea of marrow deficiency (髓海不足), liver qi depression (肝氣鬱結), and liver yang transforming into wind (肝陽化風), can be added to liver-kidney deficiency (肝腎不足), dual deficiency of qi and blood (氣血兩虛), and phlegm-heat stirring wind (痰熱動風) of the textbook. Further systematic research will be needed on them.

Objectives: To investigate the effect of enamel matrix derivative (EMD) on periodontal healing of replanted teeth in animal models. Materials and Methods: The authors searched MEDLINE, PubMed, EMBASE, Cochrane Library, Web of Knowledge and Scopus for articles published up to Oct 2012. Animal studies in which EMD was applied in transplanted or replanted teeth with adequate controls and histological data were considered. Normal periodontal healing or root resorption determined by histology after EMD was applied in replanted teeth with adequate controls was used as outcome measures. The following search strategy was used: ('Emdogain' OR 'enamel matrix proteins' OR 'enamel matrix derivative') AND ('avulsion' OR 'transplantion' OR 'autotransplantation' OR 'replantation'). Results: Six animal studies were included in the final review. There was great heterogeneity in study design among included studies. Two studies with similar study designs were identified and analyzed by a meta-analysis. The pooled estimates showed a significantly higher normal healing and surface resorption and significantly less inflammatory and replacement resorption in EMD-treated groups compared with non-EMD-treated groups. Conclusions: With the limitations of this systematic review, the use of EMD led to greater normal periodontal healing and surface root resorption and less inflammatory and replacement root resorption in the presence of periodontal ligaments. However, no definite conclusion could be drawn with regard to the effect of EMD on periodontal healing and root resorption when no periodontal ligaments exist.

Background: Previous studies on the association of oral contraceptives (OC) use and lung cancer generated inconsistent findings. The aim of this study was to confirm any definite correlation between OC use and lung cancer risk. Methods: Publications were reviewed and obtained through PubMed and EMBASE databases literature search up to November, 2013. Reference lists from retrieved articles were also reviewed. The language of publication was restricted to English. A meta-analysis was performed to evaluate the association by calculating pooled odds ratios (ORs) and 95% confidence intervals (CIs). Results: A total of 14 studies consisting of 9 case-control studies and 5 cohort studies were finally included in this meta-analysis. There was no significant association observed between OC use and lung cancer risk in the overall analysis (OR=0.91; 95% CI=0.81-1.03). There was a significant protective effect in Europe (OR=0.74; 95% CI=0.60-0.91) and a borderline significant protective effect with an adenocarcinoma histology (OR=0.90; 95% CI=0.80-1.01) in subgroup analyses. No association was observed for methodological quality of study, study design, smoking status and case number of study. Conclusion: This meta-analysis suggests that OC use is not likely to be associated with the risk of lung cancer at all. While a significant protective effect of OC use on lung cancer was observed in Europe, interpretation should be cautious because of the potential biases of low-quality studies. At the same time, more attention should be paid to the possible association of OC use with adenocarcinoma of lung. Our findings require further research, with well-conducted and large-scale epidemiological studies to confirm effects of OC use on lung cancer.

Background Understanding the female breast fascial system is of paramount importance in breast surgery. Little was written about breast ligaments. Most articles refer to Cooper's work without further anatomical studies. Lately, a horizontal septum has been described conveying nerves and vessels to the nipple areola complex. Methods During the surgical dissection of the lower part of the breast, in supero-medial technique for breast reduction operations, a fascial septum between the lower two quadrants was detected. This fibrous septum was studied through anatomic dissection of breast tissues during routine breast reshaping procedures that was done on 30 female patients. Magnetic resonance imaging (MRI) was performed preoperatively in all cases and correlated with the intraoperative findings. In the other five cases, outside the clinical study, the imaging was done during routine investigation for breast swellings. Results A vertical septum was identified in the lower part of the breast, lying at the breast meridian between the two lower quadrants. It is a tough bi-laminated structure that extends from the middle of the infra-mammary crease caudally to nipple-areola complex cranially and from the pectoral fascia posteriorly to the overlying skin anteriorly. This was proved by MRI findings. Conclusions This study describes a new inferior vertical septum which separates the lower half of the breast into two definite anatomical compartments: medial and lateral.

Although a number of studies have been conducted on the association between GSTM1 polymorphisms and lung cancer in China, this association remains elusive and controversial. To clarify the effects of GSTM1 polymorphisms on the risk of lung cancer, a meta-analysis was performed in the Chinese population. Related studies were identified from PubMed, Springer Link, Ovid, Chinese Wanfang Data Knowledge Service Platform, Chinese National Knowledge Infrastructure (CNKI), and Chinese Biology Medicine (CBM) up to 5th April 2014. A total of 45 articles (47 studies) including 6,623 cases and 7,865 controls were involved in this meta-analysis. Overall, a significant association (OR = 1.45, 95%CI: 1.32-1.60) was found between the null GSTM1 and lung cancer risk when all studies in Chinese population pooled into the meta-analysis. In subgroup analyses stratified by quality score, geographic area and source of controls, the same results were observed under all the models. This meta-analysis showed that the null GSTM1 may be a potential biomarker for lung cancer risk in Chinese, but further studies with gene-gene and gene-environment interactions are required for definite conclusions.
