  • This thesis proposes a design algorithm of an efficient space response compactor for Built-In Self-Testing of VLSI circuits. The proposed design algorithm of space compactors can be applied independently from the structure of Circuit Cnder Test. There are high hardware overhead cost in conventional space response compactors and the fault coverage is reduced by aliasing which maps faulty circuit's response to fault-free one. However, the proposed method designs space response compactors with reduced hardware overheads and does not reduce the fault coverage comparing to conventional method. Also, the proposed method can be extended to general N -input logic gate and design the most efficient space response L'Ompactors according to the characteristies of output sequence from CUT. The prolxlsed design algorithm is implemented by C language on a SUN SPARC Workstation, and some experiment results of the simulation applied to ISCAS'85 benchmark circuits with pseudo random patterns generated bv LFSR( Linear Feedback Shift Register) show the efficiency and validity of the proposed design algorithm.

  • The contract screening system is being introduced and operated as a model of advance budget reduction for local fiscal efficiency. But as the authority recognizes the contract screening system as a means of budget reduction, and companies recognize it as a means of budget curtailment, a contradictory understanding structure on the contract screening system is being formed. This research was prompted to propose a development method that will enable the contract screening system operating in Jeju Special Self-Governing Province to be appropriately established as a model of advance budget reduction. To achieve this, the operating status of the contract screening system was analyzed, and the recognition level on the contract screening system of the local government and companies was analyzed on the basis of contract screening data.

  • In general, a large-scale wireless sensor network(WSNs) is composed of hundreds of or thousands of sensor nodes. In this large-scale wireless sensor networks, it is required to maintain and manage the networks to lower management cost and obtain high energy efficiency. Users should be provided with sensing service at the level of quality for users through an efficient system. In evaluating the result data quality provided from this network to users, the number of sensors related to event detection has an important role. Accordingly, the network protocol which can provide proper QoS at the level of users demanding quality should be designed in a way such that the overall system function has not to be influenced even if some sensor nodes are in error. The energy consumption is minimized at the same time. The protocol suggested in this article is based on the LEACH protocol and is a role-based self-Organization one that is appropriate for large-scale networks which need constant monitoring.

  • Discharge measurement during flood season is very difficult. Microwave water surface current meter (MWSCM) can measures river surface velocities easily without contacting water. This study introduces its improved version, MWSCM for general use. The existing version of MWSCM is for floods so that its applicable period in a year is short. It has been improved to extend its applicability in a year. The range of measurable velocity for MWSCM for general use is extended so it can be applied during normal flows as well as high flows. MWSCM for general use can measure the velocity range of $0.03{\sim}20.0ms^{-1}$, whereas MWSCM for floods can measure the velocity range of $0.5{\sim}10.0ms^{-1}$. To make such innovation of MWSCM for general use, the applied microwave frequency of MWSCM was changed from 10 GHz to 24 GHz. Waveguide slot array antenna has been designed with the new development of the circuit of transmitting and receiving part. Improvement requests on the existing MWSCM for floods - weight lightening, measured velocity stabilization, self-test, low power consumption, and waterproof and dampproof - from the users of it have been reflected for the development of the new version of MWSCM.

  • The purpose of this study was to delve into the factors associated with the oral health promotion behaviors of college students. The subjects in this study were 453 students who attended three different colleges in Gyeonggi province. After a survey was conducted, the collected data were analyzed with SPSSWIN 12.0 program. The findings of the study were as follows: 1. Concerning the basic oral health care of college students, 54.1 percent had ever visited dental clinics over the last year, and 53.4 percent hadn't received any preventive treatment during the same period of time. 2. As to their self-perception of oral health status, 80.1 percent didn't find themselves to be in good oral health. 3. Regarding the influence of their general characteristics, their self-efficacy was statistically significantly different according to their gender (p = .022). Their control of oral health varied statistically significantly with their major(p = .000), and whether or not they smoked (p = .004) made a statistically significant difference to that as well. Their oral health knowledge differed statistically significantly with their gender (p = .000), major(p = .000) and age group(p = .000), and whether or not they smoked(p = .006) made a statistically significant difference to that as well. 4. As for correlation among the variables, better oral health promotion behaviors were found among those whose self-efficacy was higher, whose control of oral health was better and who had more knowledge on oral health. 5. Preventive treatment, control of oral health and self-efficacy were identified as the variable that affected their oral health promotion behaviors.

  • There is an urgent need to improve the tool predicting success or failure of academic achievement of nursing in Korea so as to identify as early as possible those students who should receive special instruction and to improve screening procedures for admission of nursing. The main purpose of this study is to identify the correlation between the grade point averages of courses learned and their psychological test characteristics in a baccalaureate nursing program. All 240 students, except freshmen, enrolled in Nursing Department of Seoul National University in the spring semester, 1972, participated in this study. All of the subjects completed the psychometric tests such as interest test, personality test and test of self-concept. Total grade point averages, grade point averages of general education subjects, of supporting science courses and of professional education subjects were used as performance criteria of the students. Through the calculation of product-moment correlation coefficients between the test scores and four grade point averages of each class and of total subjects, the following findings and recommendations were obtained. 1. There was so much variation in characteristics of interest test correlated with academic achievement of nursing students in each class. 2. Since the school objectives, curriculum and teaching strategies may affect predictive efficiency of characteristics of students'interest test, interest test must-be utilized in a homogeneous group in order to predict school achievement. 3. Characteristics of interest test positively correlated at significant level with total grade point averages of all subjects were scientific interest-biological, scientific interest-physical, and humanitarian interest. Scientific interest-physics: was the only characteristic positively correlated at significant level with total grade point averages and grade point averages of professional courses. 4. There were various patterns in characteristics of personality test correlated with school achievement of nursing students by class pattern and personality maturation as they progress toward higher classes. 5. A characteristic of personality test, responsibility, is in high positive correlation with academic achievement in the upper division of classes. 6. Responsibility was the sole personality factor positively correlated at significant level with total grade point averages and grade point averages of nursing courses in the total number of students. 7. There were very different correlation coefficients between characteristics of self-concept test and academic achievement according to the type of each class and type of courses they learned. 8. Characteristics of self-concept test positively correlated at significant level with total grade point averages and grade point averages of nursing courses of all students were physical self and row variability. Those who have positive concept on their own physical status and who are deficient in self-concept were higher in total grade point averages and grade point averages of professional courses than other students. 9. Scores of professional courses offered in freshmen and sophomore classes were in positive correlation with limited number of characteristics of psychological tests. In pursuit of a tool predicting successful academic achievement of nursing students, their G.P.A. during the junior and senior year of nursing will serve as the more reasonable criteria. 10. Junior students of this school were in higher positive correlation with many psychological factors than other classes.

  • Obese people experience dissatisfaction of body, depression, anxiety, and emotional disturbance by social prejudice and discrimination, further they represent decline of health-related quality of life. Exercise therapy is recommended as one of the positive treatments to improve the emotional pain of obese people. This study is to provide guideline of exercise prescription for obese people by investigating the effects of qigong exercise on psychological factors such as health-related quality of life (SF-36), self-efficiency, depression, anxiety, and fatigue in obese people. The subjects of this study were 50~60s adults participated in Golden-Wellbeing program at S university in G gu of S city and were devided into exercise (N=17) and control (N=16) group. Qigong exercise was performed twice per week for 12 weeks and SF-36, self-efficiency, depression, anxiety, and fatigue were measured before and after 12 weeks of exercise. In the 8 items of SF-36 before and after 12 weeks of qi-gong exercise, there was no significance in role limitation-emotional (F=0.187, p=0.668), mental health (F=2.043, p=0.163) between groups, but there was significance in physical functioning (F=15.151, p<0.001), role limitation-physical (F=18.278, p<0.001), social functioning (F=4.957, p=0.033), vitality (F=11.485, p=0.002), bodily pain (F=6.623, p=0.015), and general health (F=4.498, p=0.042) between groups. Also, anxiety (F=0.631, p=0.433) was not significant, whereas self-efficiency (F=6.124, p=0.019), depression (F=5.109, p=0.031), fatigue (F=7.998, p=0.008) was significant between groups. Even though qigong is slow motion and low intensity of exercise, it was found that qi-gong has exercise effect which induces mental and psychological improvement through this study.

  • Background: The purpose of this survey is to determine the job and task satisfaction of physiotherapists. These are important factors because they are directly connected to both morale and work efficiency. Methods: Data was collected from March 9th, 2013 to April 15th, 2013 using self-administered questionnaires. First, Cronbach Alpha coefficient was used to evaluate date reliability. Further data analysis used mean and standard deviation to determine frequency and satisfaction for each characteristic. To determine the significance of job and task satisfaction, T-test and an analysis of variance were performed. Also, regression analysis was used to find out a relation between job satisfaction of physiotherapist and task satisfaction of orthopaedic physical therapy. Result: This survey includes results from 197 physiotherapists who engage in orthopaedic physical therapy from major, medium and small cities. The general characteristics of survey respondents include: 112 males (56.9%), 85 females (43.1%); 123 in their twenties (62.4%), 56 in their thirties (28.4%), and 18 over forty (9.1%); 156 had less than five years work experience in orthopaedics, 25 had six to ten years, and 16 had more than eleven years work experience. In the physiotherapist's job satisfaction survey (out of 5), males averaged 3.71 and females averaged 3.43. Individuals with less than five years in the career averaged 3.5, 3.69 for between 6 to 10 years in career, 3.87 for over 11 years in career; this showed a significant difference. Results of the sub-factors of job satisfaction were 3.81 for self-esteem and 3.21 for prospect of occupation. Results of task satisfaction in orthopaedic therapy showed a significant difference between 4.03 for males and 3.66 for females. For sub-factors of task satisfaction scores were 3.81 for vision, 4.29 for task adoption, and 3.57 for task recognition. Conclusion: Physiotherapists will be satisfied when their motivation to work and morale are increased by concerns such as improving the education environment, expert physiotherapist adoption issue, and medical law revision.
