BIDANI는 활동-연구계획으로서 지역주민이 상부기관의 계획 입안자와 밀접한 관계를 유지하면서 자신의 활동과 포부를 프로그램에 반영토록 하는데 그 목표를 두고 있다. BIDANI는 지역차원의 종합개발 접근이며, 주민의 참여서비스로 지역종합개발계획(BIDP)을 수립한다. 지역의 상황분석, 문제점 우선순위 및 잠재자원의 확인은 주민에 의해 수행된다. 상향식 접근으로 참여 계획을 수립하고 BIDP를 공식화한다. 적절한 유인과 지원으로 지역주민의 참여를 촉진한다. 정부와 사립기관의 사업과 자원활용의 접근성과 효율성을 높힌다. 고위험영양불량 가족집단을 개발프로그램 활동에 참여케 하여 영양의 중요성을 인식케 한다. 정치 및 사회경제적 배려를 최하위 수준에 통합 시키토록 운영한다. 군/시장을 사업소장으로 임명하는 제도화를 통해 프로그램 수행과 지속성을 촉진한다. 따라서 시/군 종합개발프로그램 (C/MIDP)의 “하향식” 계획은 지역의 “상향식” 계획과 연계된다. 시/군지역개발훈련원을 설립하여 지역주재 요원과 주민의 계속 교육을 도모하는 것이 성공과 활력으로 유인하는 개발촉진 요소이다. 비정치적 부문, 즉 학술기관과 사립기관과의 기능적 연계를 강화한다.

이 연구에서는 우리나라 초·중·고등학교 학생을 대상으로 학년 및 학교급에 따른 학생의 과학긍정경험의 추이와 하락 원인을 조사하였다. 이를 위해 서울특별시에 있는 일반 초·중·고등학교에서 4학년~10학년 학생을 학년별로 표집한 후, 학생들의 과학긍정경험 및 하락 원인을 묻는 설문을 시행하였다. 과학긍정경험 지표 검사에 대한 일원 분산 분석 결과, 전체 평균에서는 학년과 학교급에 따라 통계적으로 유의한 차이가 없었다. 그러나 과학긍정경험의 하위 영역별로는 결과가 다소 다르게 나타났다. 즉 과학학습정서에서는 중학생보다 초등학생의 평균이 통계적으로 유의하게 높았으며, 초등학교 4학년의 평균이 중학교 1학년, 중학교 3학년, 고등학교 1학년의 평균보다 각각 유의하게 높았다. 과학관련 진로포부에서는 중학생보다 고등학생의 평균이 통계적으로 유의하게 높은 것으로 나타났다. 과학관련 자아개념, 과학학습동기, 과학관련 태도에서는 학년 및 학교급에 따른 점수 차이가 통계적으로 유의하지 않았다. 과학긍정경험의 하위 영역별 주요 하락 원인은 학교급에 따라 다소 달랐다. 이러한 결과를 바탕으로 학년 및 학교급에 따라 과학긍정경험을 향상시키는 방안을 모색하였다.

A 38-year-old man, who was diagnosed nasopharyngeal carcinoma (stage T4N2Mx) had rapidly growing lower neck mass (at level IV area) with local inflammation sign during concurrent chemoradiotherapy. After we performed Color Doppler sonography and fine needle aspiration biopsy of the neck mass, we differentiated neck soft tissue infection from tumor extension. Size of the mass decreased after antibiotics therapy. It was difficult to differentiate neck infection from tumor progression during treatment in naspharyngeal carcinoma.

This study investigated the interaction between consonants and vowels in Korean syllable perception using a speeded classification task (Garner, 1978). Experiment 1 examined whether listeners analytically perceive the component phonemes in CV monosyllables when classification is based on the component phonemes (a consonant or a vowel) and observed a significant redundancy gain and a Garner interference effect. These results imply that the perception of the component phonemes in a CV syllable is not linear. Experiment 2 examined the further relation between consonants and vowels at a subphonemic level comparing classification times based on glottal features (aspiration and lax), on place of articulation features (labial and coronal), and on vowel features (front and back). Across all feature classifications, there were significant but asymmetric interference effects. Glottal feature.based classification showed the least amount of interference effect, while vowel feature.based classification showed moderate interference, and place of articulation feature-based classification showed the most interference. These results show that glottal features are more independent to vowels, but place features are more dependent to vowels in syllable perception. To examine the three-way interaction among glottal, place of articulation, and vowel features, Experiment 3 featured a modified Garner task. The outcome of this experiment indicated that glottal consonant features are independent to both the place of articulation and vowel features, but the place of articulation features are dependent to glottal and vowel features. These results were interpreted to show that speech perception is not abstract and discrete, but nonlinear, and that the perception of features corresponds to the hierarchical organization of articulatory features which is suggested in nonlinear phonology (Clements, 1991; Browman and Goldstein, 1989).

Modern society's technological and economical changes require high-level education that involve critical thinking, problem solving, and communication with others. Thus, today's perspective of mathematics and mathematics learning recognizes a potential symbolic relationship between concrete and abstract mathematics. If the problems engage students' interests and aspiration, mathematical problems can serve as a source of their motivation. In addition, if the problems stimulate students'thinking, mathematical problems can also serve as a source of meaning and understanding. From these perspectives, the purpose of my study is to prove that mathematical modeling tasks can provide opportunities for students to attach meanings to mathematical calculations and procedures, and to manipulate symbols so that they may draw out the meanings out of the conclusion to which the symbolic manipulations lead. The review of related literature regarding mathematical modeling and model are performed as a theoretical study. I especially concentrated on the study results of Freudenthal, Fischbein, Lesh, Disessea, Blum, and Niss's model systems. We also investigate the emphasis of mathematising, the classified method of mathematical modeling, and the cognitive nature of mathematical model. And We investigate the purposes of model construction and the instructive meaning of mathematical modeling. In conclusion, we have presented the methods that promote students' effective model construction ability. First, the teaching and the learning begins with problems that reflect reality. Second, if students face problems that have too much or not enough information, they will construct useful models in the process of justifying important conjecture by attempting diverse models. Lastly, the teachers must understand the modeling cycle of the students and evaluate the effectiveness of the models that the students have constructed from their classroom observations, case study, and interaction between the learner and the teacher.

An iodized oil such as Ethiodol or Lipiodol was selectively retained in the tumor vessels of the large hepatomas as well as in the small daughter hepatomas for long periods following the intra-arterial hepatic injection of such contrast material. The specific aim of the study is to deliver a high internal radiation dose to hepatocellular carcinoma (HCC) in an attempt to control the disease. We were able to replace a small fraction of the stable iodine (I-127) of the 37% iodine in Lipiodol by the $I^{-131}$ with 100% exchange efficiency. $I^{-131}$ labeled Lipiodol was injected through the super-selected tumor feeding artery under superselection or into the proper hepatic arterial level of patients who have malignant hepatomas confirmed by aspiration cytology serum AFP and various imaging modalities. Clinical traial was performed on 43 cases during recent 6 months and follow-up observation was carried out. No severe complications or other adverse reactions were encountered until nowdays. $I^{-131}-Lipiodol$ was stable in vivo and no significant activity was noted in the thyroid, stomach, blood and urine after the injection. Only small fraction of radioisotope activity was noticed in the both side of lungs. Tumor to normal liver radio was very high. Therefore, $I^{-131}-Lipiodol$ (or P-32-Lipiodol) will be effective delivering high internal radiation dose to the tumor while delivering small radiation doses to normal tissues. Labeling, tumor dose calculation and preliminary findings will be presented.

Background: The Bethesda System for Reporting Thyroid Cytopathology is one of the main classification systems for thyroid nodules. It expects that 7% of all fine needle aspiration biopsies will be reported as atypia or follicular lesions of undetermined significance, and 5-15% of these undetermined nodules are malignant. Our study is a retrospective analysis of variables that may be associated with outcome in patients with indeterminate thyroid nodules. Materials and Methods: Patients who underwent thyroidectomy in our institution between 2010 and 2014 were retrieved from the institutional records database. Patient demographics and medical histories were recorded. All ultrasonography reports were examined for nodule features and biochemical blood levels, hormone levels and complete blood counts were recorded. Results: A total of 103 patient cytopathology reports were regarded as belonging to the undetermined category. Some 35% of patients had malignant nodules. Median preoperative red cell distribution width (RDW) level was 13.6 inthe benign group, while it was 14.3 in patients with malignancy, demonstrating a significant correlation (p=0.003). Only calcification presence was significantly different between benign and malignant groups on ultrasonography (p=0.034). Conclusions: Ultrasonography is one of the primary tools for this matter. RDW levels may become another promising tool to predict malignancy.
