Objectives : The purpose of this study was to systematically analyze and compare e acoustic sound structure of vocal major student's singing voice. Materials and Methods : The nineteen vocal major students were the subject group and healthy nineteen females were the control group for this study. The subject group was taken a strobovideolaryngoscopy by the use of flexible nasopharyngoscopy. And acoustic analysis was taken between two groups. Additionally the inquiry on usual voice problems and management was performed by thirty-six vocal major students. Results : The subject group presents many functional voice disorder findings such as AP contraction(44%), phase difference(36%) tremor(25%), posterior gap(17%), hyperadduction of vestibular fold(6%), and anterior gap(3%) on strobovideolaryngoscopy. And the vocal major students did reveal an enhanced number of high frequency harmonic partials when singing compared to the control group in the narrow band spectrum study. But there was no significant difference in jitter, shimmer and noise to harmonic ratio in both groups. Almost all vocal major students present a lot of voice problems in singing such as loss of high note(17%), loss of quiet voice(17%), effortful and tired voice(36%) etc on inquiry. And they always effort to prevent vocal dysfunction by the use of various type of method such as voice rest(28%), hydration(28%), gargling with salt(11%) etc. Conclusions : The vocal major students always take care of maintaining a good voice condition, but a lot of vocal major students revealed abnormal strobovideolaryngoscopic findings and they are absent in the conception of systemic and scientific voice management. Therefore, the young singers need a good voice training and voice therapy Program under the good ralationship of laryngologist and voice training teacher.

This study empirical analysed how student's major satisfaction affected job-seeking stress. It also analysed the mean differences of major satisfaction and job-seeking stress between two groups(IPP experienced, non-experienced groups). 200 data were collected from the field survey questionnaires administered to a quota sample of university students who had IPP experience or non-experience. For hypothesis testing, the IBM SPSS Statistics 24.0 was used. As a result of empirical research analysis, first, it was found that major satisfaction had a negative effect on job-seeking stress. Among major satisfaction sub categories, subject satisfaction had negative effects on cognitive and physical stress, and relationship satisfaction also had negative effects on cognitive and physical stress. On the other hand, general satisfaction had a negative effect only on emotional stress. Second, there was a significant difference between major satisfaction and job-seeking stress. Major satisfaction of IPP experience group was high, and the job-seeking stress was low. Third, in the group of students who practiced IPP, subject satisfaction had a negative effect on emotional and physical stress, whereas subject satisfaction in the group of students who did not practice IPP had no significant effect on job-seekingt stress. In the case of relationship satisfaction, only non-practice groups had a negative effect on cognitive stress and physical stress. In the case of general satisfaction, only the IPP group showed negative effects on emotional stress. The results of this study supported the preceding studies that major satisfaction had an effect on job-seeking stress, and the study was meaningful in that it confirmed that there were differences between the IPP experienced, non-experienced groups. Based on this results, academic and practical implications were suggested.

Objectives : The purpose of this study was to systematically analyze and compare the acoustic characteristics of vocal major students with vocal nodule when singing. Materials and Methods : Ten sopranos with vocal nodule, who have never been treated due to voice problems, were the subject group. Twenty healthy sopranos major students were the control group for this study. The vocal nodule was confirmed by stroboscopy and the acoustic and electroglottographic analysis was conducted on be groups. Additionally, an inquiry on usual voice problems during speaking and singing were performed on each of the groups. Results : The vowel /a/ was spoken and sung by sopranos of each group. There were no significant differences in Fo, jitter, shimmer, NHR at speaking and singing in either group. We did not register any significant differences of closed quotient and speed quotient in electroglottography for both groups at singing, but speed quotient was increased in subject group at speaking(p＜0.05). And the sopranos with nodule demonstrated voice fatigue(70%), strained and tired voice after long period of performance and conversation(60%) on inquiry. Conclusions : Although they had a vocal nodule, this group, who had a long period of voice training, did not present any differences in acoustic and electroglottographic problems during short performance, but, the vocalists noticed delicate voice problems after a long performance. We conclude that the voice training teacher and laryngologist must initiate voice management and speech therapy for vocal nodule, even if there is no specific abnormality in acoustic analysis.

The Purpose of this study is to verify the effect of the searcher's subject background on the result of online database searches. To achieve this purpose, an experimental method was adopted. 180 students performed online searches in the three different libraries chosen for this study. The subjects were classified into two groups according to the scores of the test. Data concerning processes, behavior, and results of the searches performed by the subjects in real situations were gathered. Immediately following the searches, the extent of their subject background were assessed through interview. The search effect consists of the 4 elements： search efficiency (the number of terms used per unit time), the number of relevant documents, the number of relevant documents per unit time, precision ratio. The major findings of this study are summarized as belows. 1. The searchers with strong subject background has significantly higher efficiency in searches made. Group A (of those with strong subject back-ground) use more search terms per unit time than Group B (of those with weak subject background) do. 2. In the searches made by those with strong subject background, more relevant documents art retrieved. 3. In the searches made by those with strong subject background, more relevant documents per unit time are retrieved. 4. The searchers with strong subject background has significantly higher precision ratio in searches made. In the searches made by those with strong subject background, more relevant documents of documents retrieved are retrieved.

The purpose of this study is to identify the effect of problem solving with task-based activities on understanding of major concepts and learning attitude in 'Applications of ICT' subject. In teaching the 4th class of 'Applications of ICT' subject, problem solving with reasoning task-based activities are used for the experimental groups and instructor-oriented teaching for the comparative groups. The results are as follows: First, no meaningful difference was found in the pretest result of concepts of ICT, while posttest found that the students with problem solving with reasoning task-based activities in experimental group marked average 5.87 point higher than the control group and showed meaningful difference at significance level p<.05. Dividing concepts about Information Communication Technology into four domains, there were no meaningful difference between two groups in the concept test about communication principles and methods and network, while the test results about the other two concepts, that is, expressions and patterns of information and compositions and types of communication network, showed the meaningful difference at significance level p<.05. Second, the research proved that the experimental group with problem solving with reasoning task-based activity teaching, compared to the control group with lecture, showed desirable change in learning attitude. From the results, the solving with reasoning task-based activity model is better teaching-learning method compared to lecture, revealing positive change in understanding major concepts of information and communication technology and learning attitude.

In the development of a university library's collection, the concept of patron-driven acquisition refers to a collection strategy that addresses users' direct information needs. In this study, an analysis of ten years' worth of book requests by user types was conducted to understand the topic preferences for efficient collection devleopment in the university library. In collection development, identifying subject areas of users' requested books is necessary for librarians to identify key areas of collection development and establish balanced collection development policies. To identify the major subject areas for each user group, KDC (Korean Decimal Classification) subject classifications were used, and network analysis techniques were applied to investigate the relationships between book topics in detail. The analysis revealed that "social sciences" emerged as the major topic across all user groups. However, in the analysis of sub-topics, "medicine" and "psychology" were distinctively identified as the major subject areas for graduate students, setting them apart from other user groups. The result of the network analysis further indicated that undergraduate students showed unique topics such as civil service, job placement, and career, which were not observed as major topic clusters in other user groups. On the other hand, graduate students tended to concentrate on a few specialized subjects, forming distinct topic clusters in the analysis.

This survey was conducted to investigate liberal arts college students' academic reading, to explore basic issues in their reading, and to provide how to improve their academic reading in their majors. The participants in this study were 457 students who enrolled in a college of liberal arts in a university. The study results represented as follows. Firstly, there were significant differences in vocabulary, reading comprehension, and fast-reading competence among student groups of different majors. Secondly, 66.9% of the students did not read widely in their major subjects throughout all departments. 67.7% of the students with low reading performance responded that they could complete college courses only with course textbook reading, course participation, and requirement submission. Thirdly, regarding the number of major subject books that the participants read, 82.1% of the students read less than 15 books, while 11.3% read less than a book. The students' academic reading hours during per week were less than 5 hours for 68.9% students and less than 10 hours for 13.9% respectively. Based on the results (departmental differences in reading competence, wide reading in major subject books, and liberal arts students' reading hours), liberal arts colleges need to design programs to guarantee quality and quantity in reading major subject books.
