The β₃-adrenergic receptor is expressed in visceral adipose tissue in humans and is thought to contribute to the regulation of the resting metabolic rate and lipolysis. We studied the influence of a mutation in the β₃ -adrenergic receptor gene(Trp64Arg) on body fat distribution, central obesity, lipid metabolism in 65 healthy young male adults. One out of 65 subjects were homozygous (Arg/Arg) for the trp64Arg mutation, 17 subjects were heterozygous (Trp/Arg), and 47 lacked the mutation(Trp/Trp). The body weight, height, body mass index, waist-to-hip ratio were similar between the subjects with- and without the mutation. Total body fat, abdominal fat amount, body fat distribution, serum total- and HDL-cholesterol, triglyceride, glucose, and insulin concentrations were also not different according to the presence or absence of the mutation. These results suggested that Trp64Arg mutation in β₃-adrenergic receptor gene is not a major contributing factor for central obesity or change in lipid metabolism in Korean young adults.

Objectives: The aim of this study was to describe the clinical characteristics of enuretic children and to evaluate the efficacy of treatments. Methods: Our study subjects enrolled were 52 children with nocturnal enuresis, who visited outpatient clinic of pediatrics in Seoul Paik Hospital and Ilsan Paik Hospital, during the period from October 1998 to August 2004. The data of gender, age, family history, symptom, clinical type of enuresis and drug therapy were collected and analyzed retrospectively. Results: The male : female ratio was 2.25 : 1. The mean age at diagnosis was 6.8 years with an age range from 4.3 years to 12.5 years. Fourty five cases(86.5%) were diagnosed as primary enuresis and 7 cases(13.5%) were diagnosed as secondary enuresis. A family history of enuresis was noted in 5 cases(9.6%) including 4 cases with parental enuresis history. The accompanying urinary symptoms were urgency(11.5%), frequency (7.7%), and dysuria(2.0%). Conclusion: We found frequent occurrences of enuresis in boys and primary type and an occasional association with a family history of enuresis. The two main treatment modalities were behavior control with an alarm system and drug therapy with imipramine, desmopressin, or oxybutynin. We recommend continuous drug medications to control nocturnal enuresis along with encouragement.

순환주제에 의한 작곡전공 교수활동 수업사례물 분석: 김용환의 “Moving Figures”를 중심으로

김영국 ( Young Guk Kim ) 한국예술교육학회 2015 예술교육연구 Vol.13 No.1

본 논문의 목적은 대학교에서 작곡전공으로 교수활동을 하고 있는 본 연구자의 수업사례물이며, 본 연구자의 학생 김용환의 학습결과물인 ‘Moving Figures’를 순환주제(cyclic theme) 중심으로 분석하는 데 있다. 이를 위해 본 연구자는 이 작품의 각 부분에서 나타나는 독립적이며 개별적인 특징을 분석하였고, 전체의 곡을 하나로 묶어주는 수단으로써 작용한 순환주제에 관해 중점적으로 분석하였다. 이로써 대학 작곡전공학생의 수업, 특히 교수과정의 내용학 측면에서 도움을 주고자 한다. 본 논문의 주제어인 ‘순환주제’는 15세기의 정선율 미사, 16세기의 패러디 미사와 같은 작품에서 출발한 음악적 아이디어인데, 고전·낭만시대의 작곡가들이 소나타 형식과 같은 다악장의 악곡에서 하나 이상의 주제가 제 1악장뿐만 아니라 다른 악장에도 나타나게 하여 음악적 아이디어를 형식적인 틀 안에 가두기 위한 방법으로서도 이용되었다. 김용환의 ‘Moving Figures’는 이러한 고전적인 형식에서 아이디어를 빌려와 현대적으로 변용시켰다. 즉 고전적인 의미의 순환주제와는 다르게 <도입부-A-B-C-A``-coda>의 총 6개 부분으로 구성된 단악장 형식 내에서 순환주제의 변용, 발전을 모색했기에 고전적 의미로써의 순환주제 개념과는 상이하며 조금 더 진보된 양상을 띤다. The subject of this thesis is a case of the present class researchers and teaching activities studied composition at the university, and analyze the historical background and cyclic form in ``Moving Figures`` of Yong-hwan Kim, (1988~ ) my student. The purpose of this thesis is to study the structure with cyclic form, harmony and study elements such as timbre on Yong-Hwan Kim‘s ’Moving Figures`` appear in each part of an independent study is to focus on the subject appears as a means of circulation that bind specifically to one picece of the total and individual characteristics. Thus, the university student majoring in composition classes, and helping in the details, particularly on aspects of teaching process. Originally cyclic form is the musical ideas from works such as the cantus firmus mass, in the 16th century parody mass of the 15th century. Composers of the classical era composer and romantic era, were used also as a way of putting a musical ideas first movement to appear in more than one subject, as well as other movements in the same piece of music in the form of a multi-movement sonata form and framework. But ``Moving Figures`` is unlike the original meaning of cyclic form, <introduction-A-B-C-A``-coda> consists of a total of six section of, and since the transformation, the development of the cyclic form is made only in the movement type, and cyclic form as a classical concept with a different sense, may be seen to have a little more advanced aspects. The musical structure used in contemporary music appears dissolved and established patterns, but ``Moving Figures`` is borrowing ideas from the classical form and transformation into comtemporary is thought to be the work that needs to be thoroughly studied. and also can be considered in analysis for contemporary musical composition trends with music educational aspects.

Tricholoma matsutake, an ectomycorrhiza that has mutual relationships with the rootlet of Pinus denisflora, forms a fruiting body that serves as a valuable food in Asia. However, the artificial culture of this fungus has not been successful. Soil fungi, including T. matsutake, coexist with many other microorganisms and plants; therefore, complex microbial communities have an influence on the fruiting body formation of T. matsutake. Here, we report on the structures of fungal communities associated with the fairy ring of T. matsutake through the pyrosequencing method. Soil samples were collected inside the fairy ring zone, in the fairy ring zone, and outside the fairy ring zone. A total of 37,125 sequencing reads were obtained and 728 to 1,962 operational taxonomic units (OTUs) were observed in the sampling zones. The fairy ring zone had the lowest OTUs and the lowest fungal diversity of all sampling zones. The number of OTUs and fungal taxa inside and outside the fairy ring zone was, respectively, about 2 times and 1.5 times higher than the fairy ring. Taxonomic analysis showed that each sampling zone has different fungal communities. In particular, out of 209 genera total, 6 genera in the fairy ring zone, such as Hemimycena, were uniquely present and 31 genera, such as Mycena, Boletopsis, and Repetophragma, were specifically absent. The results of metagenomic analysis based on the pyrosequencing indicate a decrease of fungal communities in the fairy ring zone and changes of fungal communities depending on the fairy ring growth of T. matsutake.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

This study was carried out to have basic and applied informations to find the optimum nitrogen fertilization level for organic cultivation and to investigate early growth characteristics of Schizandra chinensis Baillon. Different application levels of the organic fertilizer were based on the recommended rate of N fertilizer. Five different levels of the organic fertilizer were applied to S. chinensis and early growth responses such as the length of vine, the diameter of vine, the number of leaves, and the number of branches were investigated. Lengths of main and total vines were shown longer at the level of 1.0 time organic fertilizer than those at others. The vine length at early growth was the highest at the level of 1.0 time organic fertilizer among the treatments. Stem diameter was shown thicker level of 1.0 time organic fertilizer than others on August and September, whereas on October it was the thickest in the conventional cultivation. Number of leaf was increased higher at the level of 1.0 and 2.0 times organic fertilizer than that in the compared to conventional. The number of branches was appeared the lowest at the level of 1.0 time organic fertilizer at early growth, however they were increased through progressing their growth stages. They were not significantly difference among the treatments except for the level of 2.0 times organic fertilizer. Based on the research results, the growth of S. chinensis was commonly higher at the level of 1.0 time organic fertilizer compared to other treatments.

Gastrointestinal stromal tumor (GIST) is the most common non-epithelial neoplasm arising in the gastrointestinal tract, but this tumor is rarely seen in association with type l neurofibromatosis (NFl) Generally, the majority of GISTs are isolated neoplasm and they are sporadically found in the stomach, but the GISTs in NFl patients are usually multiple and usually found in the small intestine. We report a case of multiple GISTs in the jejunum of a 63-year-old woman diagnosed as NFl accompanied by complication of gastrointestinal bleeding, In this case, Patient had multiple cafe-au lait spots and neurofibroma on skin and had freckling on axilla and groin, and then, we made a diagnosis of NFl. Gastrointestinal bleeding is controlled by resection of multiple GISTs. Generally, only 3-5% of all gastrointestinal bleeding comes from the small bowel. Causes of small intestinal bleeding are angiodysplasia, neoplasm, NSAIDs induced ulcer etc. but, If patients have NFl accompanied by complication of gastrointestinal bleeding, GISTs on small bowel must be considered.

Recent reports indicate that shorter etching times than 60 seconds can be adopted without affecting the bond strength and clinical disadvantages. The purpose of this in vitro study was to compare the shear bone strength and to measure depth of etch at different etching time length. One hundred and eight extracted bovine lower central incisors were embedded each in a tooth cup with cold-cure acrylic resin. The facial surfaces of the teeth were ground wet with 600-, 800-, 1000-, and 1200-grit Sic papers, and finally polished with a water slurry of extrafine silicon carbide powder, washed with tap water, and dried with hot air. Nine groups of nine prepared teeth were etched with a commercial(38% phosphoric acid solution) for 0, 5, 10, 15, 20, 30, 60, 90, and 120 seconds, respectively, rinsed with tap water, and dried with hot air. One conditioned teeth from every group was selected randomly for the scanning electron microscopic examination, and the remaining eight teeth of the groups were used for measuring the push shear bond strengh after bonding brackets and immensing them in the 36.5˚C water for 24 hours. Another nine groups of three teeth were used for measuring the depth of etch and surface roughness with a surface profilometer, after pieces of adhesive tape of 3mm inner diameter positioned on the ground enamel surfaces, and etched with the above mentioned. The data obtained form the above experiments were analysed statistically with one way ANOVA and Dunkan's multiple range test with the 95% confidence level. The results and conclusion of the study were as follows; 1. The results of shear bond strength for the given experimental etching times were not statistically different, but showed the tendency of decreasing shear bone strength after over 60 seconds etching times. 2. On the scanning election microscopic examination, it was observed that the morphological patterns of etched enamel surface for 5 to 20 seconds were similar and consitent, and those for 30 to 120 seconds showed increasing over-etched patterns depending on the length of etching times, but it was not associated with the shear bond strength. 4. The surface roughness increased depending on the length of etching times, but it was not associated with the shear bond strength. 5. This experiment indicated that proper etching time with 38% phosphoric acid solution is in the range of 5 to 30 seconds.

초소형 전기장치에 의한 미세 전류가 치아이동에 미치는 효과

김동환,박영국,강승구 대한치과교정학회 2008 대한치과교정학회지 Vol.38 No.5

교정치료 본질인 치아이동을 보다 효과적으로 하기 위한 기계적 힘외의 다른 자극원으로서 전기적 자극에 대한 효용성이 부각되고 있다. 본 연구는 임상에서 초소형 전기장치에 의한 전기 자극이 교정적 치아이동에 미치는 효과를 실증하기 위해 시행되었다. 교정용 미니 스크류를 식립한 성인 여성 교정 환자 7명의 상악 견치 후방 견인 시 실험측에 150 gm의 기계적 교정력 외에 20μA의 직류 전류를 공급하는 초소형 전기 장치를 고안, 제작, 장착하여 견치의 근원심에 1일 5시간씩 4주간 전류 자극을 흘리고, 대조측에는 기계적 자극만을 가한 후, 매 주간 치아 이동량을 측정하여 치아이동에 있어서 전기자극의 효과를 검증하였다. 실험기간 동안 치아이동률에 있어서 실험군에서 대조군에 비해 1, 2째주에서 33%, 3, 4째주에서 21.4% 증가된 치아이동을 보였다. 실험군의 평균 치아 이동량은 1, 2째주가 3, 4째주에 비하여 컸으며, 그 차이는 각각 47%, 24% 증가된 치아 이동량을 보였다. 실험을 통하여 미세 전류가 적용되어 치아이동을 촉진할 수 있다는 것이 임상적으로 실증되었다. 생물학적으로 최적의 치아이동을 계획하여 치료계획을 단축시킬 수 있는 방법은 기계적 교정력과 전기자극을 동시에 가하는 것이라고 제안한다. Objective: The purpose of this study was to determine whether an exogenous electric current to the alveolar bone surrounding a tooth being orthodontically treated can enhance tooth movement in human and to verify the effect of electric currents on tooth movement in a clinical aspect. Methods: This study was performed on 7 female orthodontic patients. The electric appliance was set in the maxilla to provide a direct electric current of 20μA. The maxillary canine on one side was assigned as the experimental side, and the other as control. The experimental canine was provided with orthodontic force and electric current. The control side was given orthodontic force only. Electrical current was applied to experimental canines for 5 hours a day. The amount of canine movement was measured with an electronic caliper every week. Results: The amount of orthodontic tooth movement in the experimental side during 4 weeks was greater by 30% compared to that of the control side. The amount of increase in tooth movement in the experimental side was statistically significant. The amount of tooth movement in the experimental side during the first two weeks was greater than that in the following two weeks. The amount of weekly tooth movement in the control side was decreased gradually. Conclusions: These results suggested that the exogenous electric current from the miniature electric device might accelerate orthodontic tooth movement by one third and have the potential to reduce orthodontic treatment duration.
