Alternative therapies refer to medical treatments that are not widely taught at medical schools or available at hospitals. The increasing use of alternative therapies and the large scale acceptance of unconventional science raise challenges for dentists today. Ineffective alternative therapies can appear effective because of the placebo effect, symptom variability, short-term observations, combination with established treatments, and reporting bias. The claims of alternative therapists are useful in identifying perceived deficiencies in conventional treatments. To counter alternative practitioners' s claims include scientific research and improved access to and evaluation of the research literature.

Beer lees precursor is chosen to prepare activated carbons having different physical and chemical properties. The beer lees-based activated carbons (BL-ACs) are characterized by N<SUB>2</SUB> adsorption/desorption isotherms, adsorption energy distributions (AEDs), and X-ray photoelectric spectroscopy (XPS). Furthermore the electrochemical properties of the BL-ACs are assessed using cyclic voltammetry (CV), electrochemical impedance spectroscopy (EIS), and constant current charge/discharge method. The maximum specific capacitance (about 188F/g at discharge current of lmA/cm<SUP>2</SUP>) is obtained in 0.1M H<SUB>2</SUB>SO<SUB>4</SUB> electrolyte solution, which is a relatively low electrolyte concentration. The overall results suggest that the BL-ACs are good candidates for EDLC electrode materials.

An investigation into teachers’ perceptions of the national achievement test of primary English
Shim,KyuNam,Lee,WonKey 한국초등영어교육학회 2011 초등영어교육 Vol.17 No.3
The purpose of this study is to investigate how primary school teachers of English perceive the national achievement test of primary English (hereafter NATPE). It also aims to investigate to what extent the washback effect of NATPE has on teachers' practice in their teaching. For these purposes, the teachers’ usual way of teaching was surveyed, and an NATPE test contents were analyzed from the perspectives of teachers. From this analysis, some critical issues were raised, such as the dissonance between what the teachers do before and after the test implementation, and the impact of the test on the teachers' perception and their practices. To carry out the research, a questionnaire consisting of some open-ended questions and some close-ended ones was administerd to over 100 teachers from different areas. An in-depth interview was also conducted to 15 questionnaire respondents in order to consolidate the data obtained from the questionnaire. The results indicate that teachers do not have enough information about the NATPE in terms of the four level distinctions of English achievement, and the differences between the neighbouring levels, the way of determining the cut-off point of each level. The results also show that teachers made efforts by employing a number of methods and strategies to help students prepare for the test, and compensate for their weakness after the test.

A Model of Robot-Assisted Assessment of Primary School Students’ English Speaking
Shim,KyuNam,MIn,Deok-Gi,Lee,Seungmin 한국초등영어교육학회 2012 초등영어교육 Vol.18 No.3
This small-scale study aims to try out if an educational robot can be used as an interlocutor in the formative speaking assessment in the primary English learning classrooms. Also it aims to investigate if it could affect the learners’ emotional factors such as motivation and confidence. For these purposes, firstly, a number of theoretical issues were investigated: Difficulties of speaking assessment, principles of speaking assessment, and robot technology; secondly, the educational standards of speaking skills prescribed in the national curriculum were examined. Through which, a model of robot-assisted speaking assessment was developed and applied to the primary school students. In addition, a questionnaire survey and an interview were conducted to 13 students for the purpose of obtaining the quantitative and qualitative data regarding their emotional responses to the assessment. The results indicate that the model of robot-assisted assessment might be put into assessment practice. There are, however, still some obstacles which need to be addressed. First, the robot should be equipped with some more high-technologies such as space and voice recognition for human-robot-interaction(HRI). Second, it should also be equipped with a number of programs such as text-to-speech(TTS), speech-to-text(STT), radio-frequency identification(RFID), and tele-presents in order to allow robots to communicate with the students. Lastly, item pool of speaking assessment should be developed thought which, the teachers could access it without any difficulties. Finally, a pedagogical implication is presented based on the research results.

The community structure and dynamic analysis of shrub forest were determined at sixty-nine stands randomly selected on the Mt. Kyeryong. The shrub forest of the Mt. Kyeryong was found to be composed of Lespedeza-Weigela community and Stephanandra-Palura community through ordination method. Species groups were determined among fourty-five main species which were selected through Klapp's method. There were Stephandra-Palura species group composed of thirty species and Lespedeza-Weigela species group of fifteen species. The succession of shrub forest was determined by using species ordination method. It was assumed that there were two main succession types ; the one from Sapium community and Sasamorpha community to Lespedeze-weigela community and the other from Parthenocissus community and Acer community to Stephanandra-Palura community.

It was found that silver ion selective electrode prepared by mixing AgI with PVC by the ratio of 5:1 was hard and durable. The response potentials of this electrode were reproducible and linear within 10^-1∼10^-7M of Ag(Ⅰ) ion concentration and its slope was 62.2㎷ per decade concentration at 298K. This electrode did not show significant response to the other cations except silver ion, but had good response to iodide, chloride, bromide and cyanide anions within 10^-1∼10^-5M. It was also found that the potentials of this electrode had not been influenced to pH in range of 1.0-8.0. This electrode could be used as an indicator electrode in potentiometric titration of single halide ion and also halide mixture with standard solution of silver nitrate.

The species association of shrub layers of forest in Mt. Gyeryong was analyzed by x^2-test and coefficients of species association. The species of shrub layers were consisted of 70 species and the major species of which frequency was above 10% were contained 30 species. The higher frequency species were Lespedeza maximowczii, Lindera obtusiloba, Stephanandra insisa, Quercus serrata, Styrax obassia, Acer pseudo-sieboldianum var. koreanum, and Prunus sargentii. Classifying the species group by species association, it was divied into three kinds of species group : Carpinus erosa group, Indigofera kirilowii and Rhodoendron schlippenbachii but R. schlippenbachii group was apparently not distinguished with other species groups.

Background:?Coated SEMS (self-expandable metal stent) placement is the preferred therapy for malignant esophagorespiratory fistula (ERF) at present. Migration is more frequent in coated stent than uncoated stent. Migration can occur immediately after stent placement and is likely secondary to malpositioning, inadequate anchoring, soft nonconstricting tumors, or complete coating of the stent. The overall risk of migration is approximately 10%. To prevent migration, we have used the anchoring technique, called Shim’s technique in Korea, connecting stent to ear with silk thread.?Patients and Methods:?Seven patients with malignant ERF were included. ERF conditions liable to migration of stent were selected. The selection criteria were ERFs without stricture (3 cases), with short length of stenosis (2 cases), and with soft consistency around fistula (2 cases). The anchoring method was designed to hang stent to ear lobe. Auricle was used for a post to suspend stent by a thread until the fixation of stent on the esophageal wall. The coated stent was specially designed for antimigration which has small circumferential uncoated portion on proximal flange part of stent for fixation. After 5 days of stenting, we removed the anchoring silk from the stent. Sealing of fistula were assessed with clinical improvement and esophagogram.?Results:?There were no migrations after stent placement in all 7 cases. Symptoms of aspiration were improved in all 7 cases.?Conclusions:?The anchoring technique was useful for the prevention of stent migration in esophagorespiratory (ERF) cases, especially in the conditions that stent are apt to be migrated.
