The purpose of this study was to examine the teaching of mathematics to students labeled as low performing. An interpretive study of two urban middle school teachers is conducted to examine the bases for the teachers' decision making in the act of instructing mathematics to underachieving students. How one conducts such an examination is predicated on how one defines the act of teaching-as teacher of content or teacher of students. Both perspectives were essential to understanding the complexity of teaching mathematics to students most underserved by schooling(i.e. low SES). A variety of fields is drawn to formulate the theoretical framework. In particular, it was examined literature that addressed either the teaching of mathematics or the teaching of low SES children, since these demographic groups have traditionally exhibited low achievement levels in mathematics. These findings were coveraged in the theoretical framework and, for the purposes of this study, define the teaching of mathematics to low performing students as a function of (a) teachers' beliefs about mathematics, (b) beliefs about the reason for underachievement, (c) expectations for low performing students, (d) self-efficacy beliefs pertaining to teaching low performing students, and (e) student resistance. The findings reveal a similar journey for each teacher taken over one academic year. Teachers' initial plans reflected high expectations and senses of efficacy for raising the achievement of low performing students. These plans were largely a product of teachers' beliefs about the reasons for underachievement and external mandates such as the high-school entrance examination. Teachers held beliefs and practices that emphasized both procedural and conceptual mathematics. Student often resisted the portions of the teacher's initial practices that emphasized high-level mathematics and conceptual understanding. Teachers acquiesced to this resistance by defaulting to procedural ways of knowing and doing mathematics. The failure to engage students in learning high-level mathematics, emphasizing conceptual understanding, resulted in lowered expectations for low performing students and a reduced sense of efficacy for teaching these students.

본 연구의 목적은 첫째, 학생들이 과학적 관찰 및 규칙 발견 활동을 수행할 때 나타나는 과학적 감성 단어의 유형과 빈도, 강도를 분석하고, 둘째, 과학 지식 생성력과 과학적 감성지수(ISE)와의 상관관계를 밝히는 것이다. 이를 위해 연구에서는 먼저 선행 연구를 고찰하여 과학적 감성을 정의하고, 효과적인 지식 생성 활동을 위해 겨울눈과 화석 관찰, 씨앗과 암석 분류의 4개의 과제를 개발 하였다. 연구대상은 교원양성대학교 4학년 학생 161명으로 하였다. 피험자들은 각 과제를 수행하면서 인지적 사고과정과 느낀 과학적 감성을 기록하고 형용사 이모티콘 척도 용지에 자신의 감성 강도를 나타내었다. 연구 결과, 관찰 활동에서는 '흥미-수용-사랑-거부'의 순으로 감성유형이 나타났고, 규칙성 발견 활동에서는 '흥미-거부-수용-기대'의 순으로 감성유형이 나타났다. 각각의 감성 단어 빈도는 감성 강도와 통계적으로 상관관계가 있었다. 과학적 감성 빈도(FSE)와 과학적 감성 강도(SSE)를 곱한 과학적 감성지수(ISE)는 과학적 감성능력을 나타내는 하나의 지표로서 과학 지식 생성력과 높은 정적인 상관관계를 가진다. 개별적인 과학적 감성 지수에서는 '수용-사랑-슬픔-흥미'순으로 과학 지식 생성력과 정적인 상관관계를 나타낸다. The purposes of this study were to analyze types of scientific emotion word and to investigate the relationship between the ISE(Index of Scientific Emotion) and the ability of science-knowledge generation in subjects' scientific observation and rule-discovery. The subjects were asked to perform four scientific tasks. The tasks were developed that are suitable for scientific observation and rule-discovery. In performing tasks, the subjects were asked to describe their generated science-knowledge and scientific emotion through self-report questionnaire, performing each task. The strength of their scientific emotion was also measured using adjective emoticon check lists. In subjects' scientific observing, they showed 33.3% of interest emotion which was the biggest, 15.0% of acceptance emotion, and 11.3% of love emotion, respectively. In scientific rule-discovering, types of emotion were shown as 23.8% of interest, 21.5% of disgust, and 10.8% of acceptance, respectively. In addition, ability of science-knowledge generation was significantly correlated to ISE.

Creutzfeldt-Jacob disease (CJD) is one of the fatal prion diseases. Diagnosis of CJD is mainly based on clinical symptomatology of established criteria, characteristic electroencephalogram, specific cerebrospinal fluid protein measurement, prion protein gene analysis, prion protein isoform detection, and neuropathology. But spongiform change of brain pathology is the only definitive diagnosis of CJD. Clinical symptomatology of CJD includes behavioral disturbances, progressive dementia, cerebellar, pyramidal, and extrapyramidal signs. Most patients show progressive myoclonic jerks that involve either limbs or the entire body. The approximate incidence of CJD is 1 per million and occurs as sporadic, familial and iatrogenic forms. Variant CJD has the strong possibility of cross species transmission between human and cow. It has some differences in clinical and pathological aspects from sporadic CJD. Protease resistant prion protein of scrape isoform may lead to diverse neuronal death in CJD. Recent advannces in CJD reveal that apoptosis, proinflammatory cytokine expression and oxidative stress may play an important role of CJD pathogenesis. There areseveral therapeutic trials in CJD but no therapeutic regimensshow effective results. Although there is much progression about CJD in recent days, a lot of things still remained to be reveled.

Nevoid basal cell carcinoma syndrome (NBCCS) is inherited as an autosomal dominant trait with variable conditions, including multiple basal cell carcinoma, numerous keratocystic odontogenic tumors (KOTs) in the jaws, ectopic calcification of the falx cerebri, bifid ribs, macrocephaly, kyphoscoliosis, cleft palate, frontal and temporal bossing, mild ocular hypertelorism, mild mandibular prognathism, vertebral fusion, and so on. A 16-year-old boy visited the Dong-A University Medical Center, requiring diagnosis and treatment of multiple cystic lesions. He presented with many conditions related to NBCCS, including multiple KOTs, bifid rib, cleft lip, frontal bossing, mild ocular hypertelorism, and mild mandibular prognathism. No characteristic cutaneous manifestations (nevoid basal cell carcinoma) were observed in this patient. We report on a case of multiple KOTs associated with NBCCS with a review of the literature.

Cilostazol has both antithrombotic and cerebral vasodilating effects, and one of the mechanism is the selective inhibition of platalet cyclic AMP phosphodiesterase. Bioequivalence of two cilostazol tablets, the Pletaal^TM (Korea Otsuka Pharmaceutical Co.) and the LG Cilostazol^TM (LG Chemical Co.), was evaluated according to the guidelines of Korea Food and Drug Administration (KFDA). Sixteen normal male volunteers (20∼29 years old) were randomly divided into two groups and a randomized 2×2 cross-over study was employed. After oral administration of Pletaal^TM or LG Cilostazol^TM tablet (100㎎ cilostazol), blood samples were taken at predetermined time intervals and the serum cilostazol concentrations were determined using an HPLC method with UV/VIS detector. The pharmacokinetic parameters (AUC_t, C_max and T_max) were calculated and ANOVA was utilized for the statistical analysis. The results showed that the differences in AUC_t, C_max and T_max between two tablets based on the Pletaal^TM tablet were -5.39%, 2.32% and 4.26%, respectively. The powers (1-β) for AUC_t, C-max, and T_max were 83.81%, 96.02% and 91.04%, respectively. Minimum detectable differences (Δ) and 90% confidence intervals were all less than ±20%. All these parameters met the criteria of KFDA for bioequivalence, indicating that LG Cilostazol^TM tablet is bioequivalent to Pletaal^TM tablet.

정적인 융점측정 방법으로 benzene+n-dodecane, cyclohexane+phenol, phenol+water, water+sulfolane 및 diethylcarbonate+nitrobenzene계에 대한 고액 평형을 측정하였다. 측정된 고액평형 데이터는 문헌값과 modified UNIFAC에 의해 예측된 값과 비교하였으며, 추산값과 실험값은 ±1.61K 범위에서 잘 일치하였다. 본 연구에서 고찰된 diethylcarbonate의 융점은 기존문헌치와 큰 편차를 보여 재검증이 필요하다. Solid-liquid equilibrium(SLE) data were measured for benzene+ n-dodecane, cyclohexane+phenol phenol+water, water+sulfolane, and diethylcarbonate+ nitrobenzene systems by using static melting point measuring method. Measured SLE data were compared with the literature values and also compared with the values predicted by modified UNIFAC(Dortmund) equation. The experimental results are in good agreements with the published and estimated values, and the average deviation between the experimental values and the calculated values is ±1.16K. The measured melting point of diethylcarbonate shows some difference from literature value, and it will be certified through other experimental data for different systems.

Objectives: This study sought to evaluate the effect of simultaneous application of arthrocentesis and occlusal splint. Materials and Methods: A retrospective study of 43 patients (3 males, 40 females) whose symptoms had improved was conducted at the Department of Oral and Maxillofacial Surgery, Dong-A University Hospital between 2008 and 2010. Subjects were divided into three groups: Group A (17 patients with arthrocentesis and occlusal splints simultaneously applied), Group B (13 patients whose symptoms did not improve with occlusal splints, undergoing arthrocentesis after occlusal splint use for 8 weeks), and Group C (13 patients that only used occlusal splints). We compared these groups in maximum comfortable opening (MCO) and the visual analogue scale of pain and noise. Follow-up was performed at 1 week, 1 month, 3 months, and 6 months. Results: The improvement of symptoms was noted in all three groups, but Group A had a quicker improvement than the other groups, in terms of pain reduction and MCO increases. Conclusion: The simultaneous application of arthrocentesis and occlusal splints can reduce patient discomfort more quickly.
