LRRK2 (leucine-rich repeat kinase 2) has been identified as a gene corresponding to PARK8, an autosomal-dominant gene for familial Parkinson`s disease (PD). LRRK2 pathogenicspecific mutants induce neurotoxicity and shorten neurites. To elucidate the mechanism underlying LRRK2 expression, we constructed the LRRK2-promoter-luciferase reporter and used it for promoter analysis. We found that the glucocorticoid receptor (GR) transactivated LRRK2 in a ligand-dependent manner. Using quantitative RT-PCR and Western analysis, we further showed that treatment with dexamethasone, a synthetic GR ligand, induced LRRK2 expression at both the transcriptional and translational levels, in dopaminergic MN9D cells. Dexamethasone treatment also increased expression of α-synuclein, another PD causative gene, and enhanced transactivation of the α-synuclein promoter-luciferase reporter. In addition, dexamethasone treatment to MN9D cells weakly induced cytotoxicity based on an LDH assay. Because glucocorticoid hormones are secreted in response to stress, our data suggest that stress might be a related factor in the pathogenesis of PD. [BMB Reports 2013; 46(9): 454-459]

수종의 근관치료용 전기모터들의 반복사용과 시간에 따른 회전속도의 변화를 비교하여 근관치료용 전기모터의 회전 안정성을 평가하고자 하였다. 시간에 따라 변화하는 실제회전속도 및 전압과 전류를 측정하고, Student t-test를 통한 실제회전속도와, 반복측정분석을 통한 상관관계를 비교분석 하였다. 동일 종류의 전기모터들 사이의 모든 측정 결과들은 차이를 보이지 않았다. 모든 전기모터에서 반복사용과 시간의 흐름에 따른 회전속도의 변화는 차이를 보이지 않았다. 이상의 결과로, 본 실험에 사용된 모든 전기모터는 일정한 회전속도를 유지해야 하는 회전 안정성의 조건에 충족됨을 알 수 있으며, 반복사용과 시간에 따른 신뢰성 있는 회전속도와 안정적인 전압 및 전류의 유지가 가능하리라 생각된다. The purpose of this study was to evaluate a rotational stability of endodontic electronic motors by comparing the changes of rotational speed, depending on the number of usages and with/without static load. Twelve new endodontic electronic motors were used in this study. Non contact type digital tachometer was used for measuring the rotational speed of handpiece. True RMS Multimeter was used for measuring the voltages and the electric currents. All measurements were recorded every 10 seconds during 10 minutes and repeated 9 times. Five repetition was done per each electronic motor. To statistical analysis, student t-test, repeated measures and Scheffe's post-hoc tests were performed. In the same motor group, there was no significant difference in all measurements. In all groups, there was no significant difference in the amount of rotational speed changes depending on the number of usages and with/without static load. In the limitation of this study, the results showed that all kinds of endodontic electronic motors in this study had an established rotational stability. Therefore they could be safely used in root canal treatment with areliable maintenance of rotational speed, regardless of the number of usages and with/without load.

The purpose of this study is to search the affective contents of physical education presented in the seventh education curriculum, and to provide concrete data for improving the problems in the affective domain assessment by analyzing the reality of that assessment through surveying the teachers' thoughts and assessment criterion schemes. To reach the goal of this study, I searched affective contents presented in the seventh education curriculum after dividing it into two parts, contents and assessment. And I collected fifty-five performance assessment criterion schemes from as many schools in four cities in Kyeonggi Province, and analyzed them after classifying them into ten domains by their contents. The results are as followings ; First, in the seventh education curriculum on middle school physical education, the characteristics of the subject are prescribed and qualitative improvement of this subject is emphasized through teaching and assessing the sociality and development of sentiments, such as cooperative spirit, patience, satisfaction, sincerity and responsibility which are directly related to the physical education classes. Second, the main method of affective domain assessment was the demerit system, and the contents of assessment was about the students' uniform conditions . Many school assessed just preparing condition without assessing attitude. Concrete criterion and frequency for assessment were hardly showed in the assessment criterion schemes, so the tools for affective domain assessment was poor relatively when compared with psychomotor domain assessment. Third, the teachers recognized that affective domain in physical education was important, but they thought other teachers were concerned little about that domain. Assessment was doing not for understanding achievement degree of the class goal and improving teaching-learning method but for causing learning motive. Fourth, the mainly applied contents in affective domain assessment was the students' uniform conditions. And demerit system was widely used because it was easy but many teachers pointed out that this system had some problems from the viewpoint of the educational effect and fairness. As we've seen, the tools for assessment in schools were so poor that they were different from the contents of affective domain which was showed in the seventh education curriculum. And there were inconsistency and differences between the teachers' recognition and reality of affective domain assessment, so teachers' effort and concern are necessary.

The purpose of this study were to analyze the objectives and contents of the seventh curriculum of physical education in the elementary school to help understand the curriculum, to present the course of elementary school physical education to the elementary school teachers, and to detect problems to be a help to the next curricular revision. After analysis on this research, I got the conclusions as follows ; First, the subject objectives were analyzed on the basis of the standard of objective classification by Bloom, Bucher, Barrow, Nash. Stoodley, Brownell & Hagman, Hetherington, Irwin, and Willgoose. Second, the unit objectives were analyzed on the basis of the standard of objective classification by Bloom, Bucher, Barrow, and purpose process curriculum framework. Third, the sixth and seventh curriculums were compared and analyzed. Fourth, the contents of the seventh curriculum of physical education were analyzed. The conclusions about analysis of the objectives and contents of the seventh curriculum of physical education in the elementary school are as follows ; First, by the standard of objective classification of nine scholars as Bloom, Bucher, Barrow and so on, we can understand same distribution of term statement about psychomotor, cognitive and affective domain, this shows a unity of objectives of physical education in the seventh curriculum of physical education. The standard of objective classification as Nash, Stoodley, Brownell & Hagman, Hetherington, Irwin, Willgoose, etc. shows same term distribution, and this reflects the character of synthetic subject which shares functional, scholastic, prescriptive character of the seventh curriculum of physical education. Second, in the analytical conclusion by the standard of classification of Bloom, the terms stated best are basic exercise of psychomotor domain, exercise method of cognitive domain and exercise function of psychomotor domain. Many term distributions in the 'basic exercise' of psychomotor domain are because of the seventh curriculum of physical education in the elementary school setting the basic in the moving education simulation, and emphasize a method and function of exercise to take shape various moving desire of students. In the analytical conclusion by the standard of classification of Bucher, the terms stated best are a motor function of developmental domain of exercise, a basic exercise of developmental domain of exercise, a method of exercise of cognitive domain. The seventh curriculum of physical education in the elementary school is based on moving education simulation, and show up many term distributions about 'motor function' and 'basic exercise' of developmental domain of exercise. The method of exercise is emphasized to take shape various physical activity and moving desire. In the analytical conclusion by the standard of classification of Barrow, the terms stated best are a understanding about the health of cognitive developmental domain and principal of good physical motion exercise, sports' function of developmental domain of psychological exercise and attitude of social developmental domain. The subordinate objectives of the seventh curriculum of physical education in the elementary school emphasize a motor function that participate actively to various exercise, and improve sports function with a background about understanding of principal of health and good physical moving exercise to improve physical strength and psychological health, and emphasize desirable motor attitudes. In the analytical conclusion by the standard of classification and purpose process curriculum framework(PPCF), the terms stated best are conquest of environment, social interaction and individual developmental domain, and each conceptional element has same distribution so as character prescribed in the seventh curriculum of physical education, don't emphasize only one domain, cognition or affective domain but pursuit external value, that is, realization of moving and healthy preservation and improvement, affective refinement, social cultivation through physical education in the elementary school to contribute to improve quality for life of the human. Third, the conclusions of comparison and analysis about the sixth curriculum and the seventh curriculum of physical education are nearly same, but the seventh curriculum is presented to nation common basic of physical education curriculum bounding elementary, secondary school. And the 'method' section is divided a teaching & learning method and a standard of textbook's development and discussion, and the standard of textbook's development and discussion that undertakes a important responsibility to practice of curriculum was presented newly. The contents are organized by objective and affective domain.

This paper dealt with the histological feature of the Pekin duck olfactory mucosa and the specificity of the types of mucopolysaccharides present in the secretory cells of the duck olfactory mucosa. The nasal parts of ducks (1-week-old and 10-week-old) were fixed with 10% neutral formalin, decalcified, embedded in paraffin. Serial sections were cut 5 um thick and stained with alcian blue(pH 2.5) to demonstrate acidic mucopolysaccharides and the periodic acid-Schiff reaction to identify neutral mucopolysaccharides. The results were summarized as follows. 1. The duck olfactory mucosa consisted of the olfactory epithelia which compose of the receptor neurons, supporting cells, basal cells and goblet cells, and the lamina propria which contained Bowman's glands, olfactory nerve bunbles and connective tissue cells. 2. The thickness of the olfactory mucosa was 121.5±25.67um in the 1-week-old ducks, and 202±45.82km in the 10-week-old ducks. Increased thickness of olfactory mucosa was due to the increased thickness of lamina propria. 3. Histochemical techniques of the olfactory mucosa in 10-week-old ducks demonstrated that Goblet cells, sppporting cells and Bowman's gland contained both neutral and acidic mucopolysacc harides, the neutral mucopolysaccharides staining became enhanced first in the Goblet cells and Bowman's gland, and then in supporting cells. In 1-week-old ducks, both acidic and neutral mucopolysaccharides of Goblet cells reacted strongly, but those of supporting cells and Bowman's gland reacted presumably.

Demodulation wants to adaptive equalizer to minimize interference of intersymbol which generate in multipath fading channel results from signal time and variety multi propagation through channel in digital radio network systems. Therefore using transition ratio of transfer and receiver system and the number of forward and backward using existing individual taps, we study improvement algorithms which generated bit error ratio by signal in frequence select fading. We analysis and compare linear equalizer and decision feedback nonlinear equalizer. Proposed algorithm is more efficent in fading environment when compared of step size by channel character which estimated existing least square and ITLMS algorithm. In this paper, using ITLMS algorithm by decision feedback BER is reduced for intersymbol interference by narrowband TDMA multipath fading in invironment without individual tap weight overlay.
