We analyzed the chirp sound and behavior of Teleogryllus emma with observation system, which was consisted of computer, ccd-camera and microphone. Computational methods of wavelet transformation and Self-Organizing Maps (SOM) were utilized to characterized the chirp sound of insect species for automatic counting in this study. Wavelets were initially applied to feature extraction of the chirp sound. Wavelet coefficients were accordingly calculated based on the basis function (e.g., Morlet). The obtained coefficients were subsequently provided to count number of chirps in each song. Sound structure of insect specimens consisted with long chirp and short chirp and the patterns of song were grouped by frequency of long chirp and short chirp. The song patterns of insect specimens were divided by Self-Organizing Map (SOM) that was used number of chirp as input data. Application of computational methods to automatic detection of chirp sound was further discussed for obtaining objective assessment in behavior science.

This thesis is about the present position of research of North Korean Poetry. It put much importance on the aspect of transfiguration of a point of view of the research of North Korean Literature. It can be named as the progress from the totalitarian through the immanent and the immanent- critical, to the comparative social aspect. These aspects were appeared as the comprehension and introduction of North Korean poetry, the analysis of it with critical distance, and the comparative study of South and North Korean poetry. This change of standpoint was possible since North Korean Literature were regarded as a national literature and further more as unification literature or integration literature of both nations. Despite of transformation of the aspect, however, there has been yet the mixed loading of studies in the immanent and the immanent-critical approaches. This implies that there are still lots of documents of North Korean poetry yet to be introduced as they are. This is the task of which has to be solved thoroughly. Nevertheless there is the progress of research of North Korean poetry and the emergence of the treatise of works and writers of North Korean, it is still in need to write newly about the history of North Korean poetry on these basis. It produces not only contrary evidence of the plentiful existence of objects of research of North Korean poetry but also the tasks of research of them in various points of view.

This study was designed to investigate the effect of a year aerobic exercise training on body composition, isokinetic knee and trunk muscular strength of elders. The subjects for this study were eighty healthy elderly people who were members of seniors tower at Song-Do Hospital and didn`t have any history of cardiorepiratory disease. Subjects have been trained three times a week for a year. The exercise program was made up of a 15-minute warm-up, cool-down. Stretching was performed every eight minutes for the prevention of injuries which could occur during the main exercise and quick recovery of the used muscle. Aerobic training was performed for each 15-20minutes using the treadmill and cycle ergometer at the intensity of 50-70% HRmax. For the data, all the measurements were represented by mean and standard deviation using SAS package(version 6.12). Statistical techniques for data analysis were paired t-test to determine the difference between pre and post exercise program. The 5% level of significance was used as the critical level for acceptance of hypotheses for the study. The following results were obtained from this study. 1. There is a statistically significant difference in the VO_2max, fat mass, lean mass and %body fat both old men and women after a year training. 2. There is not a statistically significant difference in the weight, WHR and thigh circumference both old men and women after a year training. 3. There is a statistically significant difference in the right knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training. 4. There is a statistically significant difference in the left knee flexor/extensor peak torque, peak torque % body weight, total work and total work % body weight both old men and women after a year training.

본 연구의 목적은 청소년 운동선수의 폭력실태 및 괴롭힘에 대한 심리적 반응을 알아보고 폭력을 행사하는 가해자와 폭력을 당하는 피해자의 특성과 원인을 파악하여 이를 예방하는 것이었다. 또한 폭력과 괴롭힘 속에서도 운동을 지속하는 청소년 운동선수들의 심리 상태를 알아보았다. 피험자는 청소년 운동 선수 30명을 대상으로 실시하였으며 운동 종목은 축구 와 농구, 야구 선수로 한정하여 실시하였다. 본 연구는 피험자들에게 반 구조화된 인터뷰의 질의 내용을 녹취하여 선수들의 심리상태를 파악하였고 선수들에 대한 응답 내용은 질적 연구에서 사용하는 귀납적 요인 분석 절차를 사용하여 분석하였다. 그 결과 청소년 운동선수들에게 가장 많은 물리적 언어적 폭력을 행사하는 대상은 '지도자'와 '선배집단'이었으며 '부모'도 언어적 폭력에서는 높은 빈도 수를 나타냈다. 그리고 폭력과 괴롭힘을 경험한 청소년 운동선수의 심리적 반응은 가해자에 따라 다양하게 표출되었으며, 폭력 가해자의 특성은 운동 집단에서 운동 수준이 낮은 것으로 나타났고, 습관적으로 폭력을 행사하는 경향을 보였다. 또한 피해자의 특성은 자신에 대한 자아개념이 높고 자신의 주장을 강하게 표현할 때 집단으로부터 괴롭힘을 당하는 것으로 나타났다. 마지막으로 폭력과 괴롭힘 속에서도 운동을 지속하는 이유는 자신이 좋아서 운동을 계속한다가 가장 높은 빈도 수를 나타냈다. 이러한 연구결과를 종합해 볼 때 폭력행위는 청소년 운동 선수들에게 심각한 심리적 폐해를 가져다 주는 것으로 나타났다. 따라서 이러한 폐해를 최소화하고 운동이 교육의 장으로서 기능을 다하기 위해서는 운동현장에서 발생하는 폭력행위에 대한 관심과 대책마련이 절실히 필요한 것으로 나타났다. The primary purpose of the study was to identify the psychological reaction of adolescent athletes to violence and bullying, the characteristics of victims, and the causes of violence. The second purpose of the study was to explore the psychological stress of the adolescent athletes under continuing violence. Thirty athletes participated in the study. The participants were football, basketball and baseball players. Semistructured interviews, which were recoded, were utilized to examine the psychological states of the participants. Inductive factor analysis was used to classify the dimensions of the interview contents. The result indicated that the coaches and senior members showed the worst violence pattern and parents demonstrated higher frequency of verbal violence. The psychological reaction of the athletes depended upon the status in their team. The violence assaulters were usually low in their ability. They showed violence regularly. When victims were high in their self-esteem and assertive, they were more bothered from their coaches and senior members. The reason why the adolescent athletes participated in exercise despite of the violence was simply that they liked their sport. To make summary of the study, violence and bullying brings serious psychological problems to adolescent athletes. Thus, coaches and teachers should pay more attention to them.

As an excitation system of the synchronous generator, an exciter which is directly connected to the main shaft, comprising some restrictions by the increasing capacity under the condition of commutation, has generally been used. In order to solve the restriction problem as well as to operate the generator without difficulty, it is desired to get rid of electrical sliding contacts such as brush and slip ring. To eliminate these electrical sliding contacts, several types of brushless generators have been developed, one of which being understood to be the self-excited brushless single-phase synchronous generator. In this paper, the results of experimental test about the characteristics are analyzed. There are not a few possibilities in the CT connection wherein the load current affects the exciting current.

The role and importance of groundwater are increased with the deficiency of surface water and contamination of river on the development and management of water resources. But in recent, imprudent development gave the negative impact on the aspect of the quantity and quality of groundwater. For example, the excessive pumping leads to exhaution of groundwater, and waste materials bring about contamination of groundwater. On the contaminant problem, the groundwater flow is the important media of pollutant transport and its phase is different hydraulic conductivity. Therefore, 2-D numerical model using FEM is developed. To verify this numerical model, it is compared with Theis's analytical solution for unsteady groundwater flow and existed model(used FDM). In this study, numerical model(used FEM) gives good agreement between analytical solution and existed model(used FDM). In this numerical simulation, homogeneous aquifer is supposed to use coarse sand, heterogeneous aquifer is supposed to consist of coarse sand and coarse gravel, and coarse sand and silt. The result of numerical simulation generally shows good agreements with real groundwater flow through homogeneous and heterogeneous aquifer.
