Robert Schumann composed nearly all of his significant piano works in the decade from approximately 1829 to 1839. The majority of these exemplify traditional formal types, including three sonatas, three sets of variations, two sets of etudes, several independent pieces, and a number of collection of pieces. However, several of Schumann’s most well-known works from this period, the so-called "piano cycles," have no real precedent among works by earlier composers. In researching the literature on cycles, I have found no detailed analytic approaches focusing on Schumann’s formal organization in his cycles. Music historians and theorists often dismiss the importance of formal consideration in Schumann’s cycles and postulate that Schumann instinctively juxtaposed individual pieces to form a collection without much coherent organization. I, however, suggest that Schumann's cycles result from preconceived plans that govern overall tonal structure and control the formation of details, relating them to a larger context. I also suggest that Schumann's piano cycles can be divided into three types: 1. Works such as Camaual, Op. 9, in which many brief pieces are linked by a large-scale coherent key scheme, recurring motives, and referential tonalities. 2. Compositions like Kreisleriana, Op. 16, in which the individual movements are lengthier than in those of the first type, and for the most part display conventional forms. This type of cycle consists of fewer movements, and often suggests a conventional multi-movement arrangement such as might be found in a sonata. 3. The third type contains only three works: the Arabeske, Blumenstuck, and Humoreske. This third type is a hybrid of the first and second types; there are fewer numbers of movements, as in type 2; but these movements are relatively shorter, as in type 1. The third type, furthermore, has other special features; these cycles are thematically unified throughout and in some respects suggest a long single movement with well-defined sections (for example, a Rondo). With these two suggestions, the third part of my study investigates how unity is supported on multiple levels in Schumann’s Kreisleriana. My methodology involves the following procedures: 1. Aspects of harmonic features: Important harmonic events and keys of upcoming movements are prepared and anticipated in preceding movements. And the presence of many harmonically open structures facilitates the establishment of strong local connections between sections and movement of Kreisleriana. 2. Principles of formal design including the relationships between the form of individual movements and the cyclic role within cycle.

The purpose of this study is the investigation of pitch-class multiplication and the application of the technique in the music of Pierre Boulez based on his composition Le mcniaui sans maître (1952-55). My study proceeds in two parts. The first part provides an examination of pitch-class multiplication. The pitch organization of this work are derived from a twelve-tone row by the transposition of its segmental subsets, which Boulez calls multiplication. In the first part, I examine the process of multiplication and how it works in Le marteau. In the second part attention is paid mainly to the analysis of pitch structure and formal portions, focusing on the third and seventh movement. In the analysis of the movements I examine the features of pitch organization derived from multiplication, and how Boulez uses it in order to control and organize not only structure of pitch-class but also overall structure of the work.

슈만의 피아노연곡에 나타난 단편성과 연속성

배재희 ( Jae Hee Bae ) 이화여자대학교 음악연구소 2006 이화음악논집 Vol.10 No.2

본 논문은 낭만연곡의 이론적 고찰과 실제 곡의 분석을 통한 피아노연곡의 단편성과 연속성을 연구하는 것을 그 목적으로 한다. 논문은 크게 세 부분으로 나뉘어 진행되며 그 순서는 다음과 같다. 첫 번째 부분에서는 낭만연곡에 관한 일반적 정의에서 시작하여 코마 이후 지난 40여년 간 진행된, 낭만연곡을 하나의 장르로 인정하고 정의하고자 했던 일련의 연구들을 정리하고자 한다. 이를 통하여 낭만연곡에 관한 기본적인 정의, 개념, 인식의 변화 및 낭만연곡을 이론적으로 어떻게 정의할 수 있는지 살펴보게 될 것이다. 두 번째 부분에서는 슈만의 피아노 연곡에서 보이는 일반적인 특징 및 이의 분류 등이 연구될 것이다. 슈만의 피아노연곡은 구조적 종지의 부재 또는 조성적 모호함 등으로 인해 개별악장의 단편성을 보이게 되며 이러한 개별악장의 불완전함은 연속되는 인접악장과의 국소적인 연결을 가능하게 함으로써 전체 연곡의 순환 구조를 가능하게 한다. 논문의 마지막 부분에서는 슈만의 「카니발」(Carnaval), Op. 9의 분석을 통해 피아노연곡의 개별악장이 연곡의 구성요소로서의 존재하게 하는 단편성 및 인접 악장들 간의 국소적 연결을 가능하게 하는 연속성에 관하여 연구할 것이다. Musicians have long recognized that certain pieces of music are organized as cycles, but it is far from clear exactly what this cyclical organization consists of. Musical cycles are usually characterized as distinct from suites, variation set, or multi-movement pieces, but no satisfactory criteria for distinguishing these types of pieces have ever been proposed. Cycles display a special kind of unity or coherence though suites and multi-movement pieces are also unified and coherent. So what is this special kind of unity displayed by cycles? The problem is complicated by the historical fact that the first cycles were collections of songs. Only in the 1830s do cycles of purely instrumental pieces begin to appear, primarily in the music of Schumann. Song cycles present special problems for the analyst in terms of their formal organization, but also display unifying factors not available to purely instrumental cycles; the texts of successive songs often suggest narrative paths through song cycles. Comparable analytical strategies for instrumental cycles are more difficult to establish. This paper studies the nineteenth-century cycle in general and Schumann`s Carnaval, opus 9, in particular. My study proceeds in three parts. In the first part, I thoroughly investigate the origins and development of cycles by surveying selected sources of cycles. I then survey scholarly studies from different trends of studies. In the second part, I identify organizational criteria for different kinds of piano cycles that are found among the works of Schumann. In the third part of this study, I try to demonstrate how the individual songs fit into the whole. My study mainly examines two aspects of Schumann`s Carnaval: Features of the structure of the individual movements, fragment, and local continuity between adjacent movements, continuity. It is the unusual nature of the forms of the individual movements that suggest that they are not complete and isolate musical works, but parts of a larger whole. Because of the lack of closure or tonal ambiguity, some movements show fragmentary character and these movements combine with adjacent movements that then project strong local continuity that influences the overall structure. My intention of this study is to discover any unusual or striking characteristics of the individual movements that might relate to their being members of a cycle.

본 연구는 특수교육 교사의 직업 정체성이 직무 스트레스에 미치는 영향을 알아보는데 목적을 두고, 전국의 특수학교 및 특수학급에 재직 중인 특수교육 교사 171명을 대상으로 그들의 직업정체성과 직무 스트레스를 측정하여 분석했다. 본 연구의 결과 첫째, 특수교육 교사의 직업 정체성은 근무 기관의 유형, 성별, 학교급별, 교육경력에 따라 유의한 차이가 나타나지 않았으나, 정체성에 따라 정체성 하위, 정체성 중위, 정체성 상위 집단으로 분류되는 것으로 나타났고, 둘째, 특수교육 교사의 직무 스트레스는 남성 교사보다 여성 교사들이 더욱 과중하게 받는 것으로 나타났고, 스트레스 요인에 따라 내적 귀인 그룹, 외적 귀인 그룹, 일반적 귀인 그룹으로 분류되는 것으로 나타났으며, 셋째, 특수교육 교사의 사명감’이 직무 스트레스와 유의한 부적 상관성을 지니는 것으로 나타났다. 따라서 특수교육 교사의 사명감이 특수교육 교사의 직무 스트레스를 조절하고 관리하는데 있어 중요한 변수임을 보여준다고 할 수 있다. The purpose of this study was to find out how teacher identity, which is internally formed by special education teachers, affected by job stress, and the analysis was conducted after selecting 171 special education teachers serving in special schools and special classes nationwide. The results of the study showed that, first of all, there were no significant differences in occupational identity in the types, sex, school grades, or educational background of the work force, such as special schools or special classes. By analyzing the occupational identity characteristics of the study subjects into three cluster types, the three groups were classified as lower identity, middle identity, and upper identity, focusing on the degree and tendency of establishing identity, and each cluster showed a uniform distribution of numbers by sub-region. Second, task stress tests by special education teachers showed significant differences in gender factors. The survey results showed that women s special education teachers are under more job stress than men s special education teachers. The results of a cluster analysis at the task stress level were divided into groups of internal and external attribution of stress factors, and groups of general attribution. All clusters had a high parent-related stress score. Third, it has been shown that the special education teachers sense of mission in particular has a significant incompatibility between task stress in the influence of professional identity of special education teachers on job stress. This contrasts with pride, persistence, job mismatch of individuals, and unity and empathy that do not show any particular correlation with stress. This can be said to show that teacher mission is an important variable in controlling and managing job stress for special education teachers.

The purpose of this study was to through the kinetics analysis on the fente motion in fencing, provide the basic data by which a training method can be found to improve the fencing techniques for the beginners and players. To do so, this study chose 7 woman fencer as test objects and recorded their motions to analyze time consumed, the velocity of blade, the angles of a joint and ground reaction force. First, the total duration time came out to be 0.56±0.11s. The shortest duration time occurred in phase 2, from the moment the knee of the front feet stretches and until the foot touches the ground. Second, COM position stretched in forward direction and vertical displacement gradually moved lower. Third, COM velocity appeared moving the fastest to all direction at the moment the knee joint stretches. Fourth, in terms of the angle of the upper extremity joints, the moment when the blade pokes the effective surface, the shoulder angle of the hand holding the blade stretched elbow joints at maximum. Fifth, in terms of the angle of lower limb joints, when the blade pokes the effective surface, it bends hip and knee joints the greatest. Six, speed of the point of the blade was fastest when the knee joints stretched. Seven, ground reaction force was at maximum when the front feet is lifted from the ground until it falls. It shows the power of control at the moment of poking.

Background: Merkel cell carcinoma is an uncommon primary cutaneous neuroendocrine cancer. It is a highly aggressive cancer with high rates of local recurrence and nodal metastasis. While there are some case reports on Korean patients with Merkel cell carcinoma, there has been no comparison study between Western patients and Korean patients regarding its clinical features. Objective: This study aimed to identify the clinical features of Merkel cell carcinoma in Korean patients and compare them with those seen in Western studies. Methods: We retrospectively reviewed the medical records of patients who were diagnosed with Merkel cell carcinoma between January 1995 and May 2019. Clinical features were compared with those seen in Western studies. Results: Thirty-one patients were enrolled in the analysis. The mean age of onset was 67.6 years, and there were more female patients (1:1.58). The head and neck was the most common primary site (38.7%, 12/31). Patients treated by surgical methods alone were the most common (58.1%, 18/31). Twelve patients (38.7%) had recurrence, and seven patients (22.6%) died of Merkel cell carcinoma. Patients younger than 70 years were more frequent in Korea than in Western countries (Fishers exact test, p<0.05). In addition, patients with distant metastasis were less frequent in Korea than in Western countries (Fishers exact test, p<0.05). Conclusion: Compared with Western studies, there were no differences between demographic and clinical features, except that older patients and patients with distant metastasis were less frequent in Korea.
