Stethoscopic auscultation is still one of the primary tools for the diagnosis of heart diseases due to its easy accessibility and relatively low cost. It is, however, a difficult skill to acquire. Many research efforts have been done on the automatic classification of heart sound signals to support clinicians in heart sound diagnosis. Recently, hidden Markov models (HMMs) have been used quite successfully in the automatic classification of the heart sound signal. However, in the classification using HMMs, there are so many heart sound signal types that it is not reasonable to assign a new class to each of them. In this paper, rather than constructing an HMM for each signal type, we propose to build an HMM for a set of acoustically-similar signal types. To define the classes, we use the KL (Kullback-Leibler) distance between different signal types to determine if they should belong to the same class. From the classification experiments on the heart sound data consisting of 25 different types of signals, the proposed method proved to be quite efficient in determining the optimal set of classes. Also we found that the class determination approach produced better results than the heuristic class assignment method.

This paper focused to classify the consumption stress coping types among married women consumers and to investigate the differences of socio-economic variables, social class, perceived health status, and consumption stress among coping types. Data were collected from 500 married women through online surveys in South Korea. Two factors of consumption stress(consumption stress before purchase, consumption stress after purchase), and three factors of consumption stress coping(Social support coping, problem solving focused coping, Passive avoidance coping) were identified. K-mean cluster analysis classified into 4 coping types with consumption stress coping. 15% of the sample were included to the passive coping type, and 25% were classified into the ambivalent coping type. 26.8% of the sample were identified to the active coping type, and 35.2% were maladaptive coping type. There were significant differences among the consumption stress coping types on education, family income, social class, health status, consumption stress after purchase. Consumer education programs should develop and implement especially for passive coping type and maladaptive coping type to cope effectively with consumption stress.

It is the aim of this study to observe the distribution of various facial types in class III malocclusion and to characterize the craniofacial features of the very facial types. Cephalometric headptates of a hundred and ten persons showing bilateral class III malocclusion whose mean age was 12.51 years and sixty nine persons of normal occlusion whose mean age was 12.23 years were measured and statistically analyzed. The following summary and conclusions were drawn. 1. Affording the bases for SNA and SNB, $35.45\%$ of sample showed normally positioned maxilla and protruded mandible, $30.00\%$ for retruded maxilla and normally positioned mandible, $15.45\%$ for retruded maxilla and protruded mandible, $10.90\%$ for both maxilla and mandible within normal range and $8.20\%$ for miscellaneous types were arranged in class III malocclusion. 2. $52.72\%$ of sample showed neutrodiveigent, $35.45\%$ for hyperdivergent and $11.81\%$ manifested hypodivergent mandible in class III malocclusion. 3. Providing the bases for facial and mandibular planes, $33.63\%$ of sample showed prognathic and neutrodivergent, $20.90\%$ for mesognathic and hyperdivergent, $17.27\%$ for prognathic and hyperdivergent and $15.45\%$ for mesognathic and neutrodivergent were arranged in class III malocclusion. 4. The class III malocclusion brought out shorter cranial base, smaller saddle angle, and larger articular and genial angle. It showed retropositioned maxilla and forward positioned mandible in spite of no significant differences in linear measurements of mandible. Anterior lower facial height was significantly larger in class III malocclusion, while posterior total facial and anterior total facial heights exhibited no significant differences. 5. It is suggested class III malocclusion was attributed to shorter cranial base, smaller saddle angle, maxillary deficiency and/or retrusion, mandibular excess and/or protrusion, excessive vertical growth of the anterior lower face, and their complex as well.

The purpose of this study is to investigate Korean primary school English teachers' beliefs on self-directed teaching and learning for facilitating student's self-directed learning. A survey was conducted, using 315 primary school teachers as participants. According to different school areas, sex, English teaching careers, and types of English teaching like classroom teachers or English specialist teachers, beliefs on teachers' self-directed teaching were studied based on class planning, class process, utilization of human resources, development and utilization of teaching materials and class evaluation. The results of this study are as follows: first, differences were not shown except class planning according to teachers from different school areas. Second, sex and beliefs of teachers' self-directed teaching had nothing in common. Third, differences were shown in class planning and class process, according to English teaching careers. Finally, according to types of English teaching, differences were shown in class process and development and utilization of teaching materials. The study suggests that it is necessary to conduct other studies for observing primary English classrooms focusing on teacher's self-directed decision-making.

This study provides a descriptive and analytical account of major aspects of urban development and transformation of housing types of Italian Firenze from the 13th century to the 19th century. It is a typo-morphological depiction of urban spatial structure of the extraordinary city, Firenze, the center of Italian Renaissance. And this study has proceeded on the assumption that the evolving form of the urban structure and housing types cannot be understood without reference to the larger context of political, economic, and social life. Based on these backgrounds, the purpose of this study is threefold: to provide a comprehensive discussion of general characteristics of urban spatial structure of Firenze, and to explain the process of formation of working-class neighborhoods by constructing new city wall in later 13th century, and to discuss transformation of housing types of the working-class neighborhood with understanding the mechanism of existence of housing in the newly formed residential neighborhoods. The development of residential neighborhoods was pursued by 'planned' manner through forming square-shaped blocks, and characterized by the subdivision of larger properties into standardized building lots for the construction of houses. On the bases of documentary evidences, several ecclesiastical institutions are identified as the agents of a distinctive type of development. While the institutions did the major role for developing lands, the construction of houses was done by small scale construction agents with moderate amount of properties. The major housing type of working-class neighborhoods of Firenze has been the 'casa a schiera' characterized by the form of narrow front and long depth. The type was generalized by the newly formed middle and working-class of Firenze which grew their body very rapidly, Even though the type assumed very uniform in its fen there were many variations. And through passing time, the casa a schiera developed to be multi-family housing, and the level of variation became deepen. Eventually, transformation of housing type of Firenze was ended by appearance of the 'casa in linea', which was very similar to modern apartment in its spatial organization.

Java 에서 원시 타입과 클래스 타입간에 호환성이 제공되지 않으므로 원시값이 클래스 타입의 변수에 저장되지 못하며, 클래스 타입의 값이 원시 타입 변수에 저장되지 못한다. 객체가 필요한 곳에서 원시값을 사용하기 위해서는 원시 값을 저장하는 래퍼 클래스의 객체 생성이 필요하며, 패러 클래스의 객체에서 저장된 원시 값을 꺼내기 위해서는 특정 메소드를 호출하여야 한다.이러한 불편함과 변환시의 오류를 줄이기 위하여 본 논문에서는 Java의 원시타입과 래퍼 클래스 타입의 호환성 제공을 위한 변환방법을 제안하였다. 원시 타입과 래퍼 클래스 타입간의 호환성 뿐 아니라 원시 타입간의 호환성에 상응하는 래퍼 클래스간의 호환성도 제공하기 위해 래퍼 클래스 계층방법, java.lang.Number 클래스 이용방법, 래퍼 인터페이스 계층방법 등 3가지 변환방법을 제시하였다. 이들 방법의 비교분석과 성능측정을 통하여 래퍼 인터페이스 계층방법이 가장 우수한 방법임을 확인하였다.

This research This research aims at developing systemic evaluation model in terms of biotope preservation through reports, literatures, and expert survey analysis by implementing biotope structure analysis in area level with selecting Hyunpoong and Yuga-myeon, Dalseong county, Daegu metropolitan city as a site. First of all, as a result of biotope type classification of research site, biotope type groups are classified into total 13, and its biotope types are divided into total 61. Also, as a result of literature analysis, total 18 items are drawn such as diversity of biotope typical species as a index item to assess the preservation value of biotope, and the first evaluation index are divided into 10 and the second ones are divided into 8 according to characteristic of index items. As a result of expert survey analysis, All 10 index items, first evaluation index, show high importance average (above 4.7). As a result of implementation of main cause for categorizing evaluation index by characteristic, there are 3 factors such as 'obstructive factor.' Based on above survey analysis result, as a result of estimating the weight of each item, 'restoration factor' showed the highest, 3.4541, but 'factor of habitat stability' showed 3.1468, which is the lowest The systemic value evaluation was set by comprehensively analyzing these results. As a result of biotope preservation value evaluation through applying research site, total 19 types which are abundant in vegetation are classified into I class, 12 types in II class, 5 types in III class, 10 types in IV class, and 15 types in V class respectively. Lastly, as a result of second evaluation, it is analyzed that there are 17 special meaningful space to preserve species and biotope(1a, 1b) and 61 meaningful space to preserve species (2a, 2b, 2c).

This study surveyed 2nd graders of B high school and 1st graders of A university in Gyeongnam on factors such as behavior control and interaction in non-face-to-face classes, easy or difficult concepts presented in chemistry I and general chemistry textbooks. Based on the results of the survey, the effect of changes in the difficulty level of concepts presented in chemistry I and general chemistry and changes in class types (face-to-face and non-face-to-face) on students' academic achievement by level was compared and analyzed. In the face-to-face class, the average score between the first and second semesters was similar according to the change in the difficulty of the concepts presented in chemistry I and general chemistry. In the non-face-to-face class, the average score of chemistry I in the second semester was quite low, and the average score of general chemistry was rather high. In non-face-to-face classes, the average score of chemistry I in the second semester of low-level students was significantly lowered due to changes in the difficulty of the concept and changes in class types on academic achievement by level. In the case of 10% of students at the lower level, the academic achievement of chemistry I decreased in both the second semester regardless of the changes in the difficulty level of concepts and the changes in class types.
