Objectives: The purpose of this study was to analyze the factors that affect the test anxiety among dental hygiene students, including mental health and academic self-efficacy. Methods: A self-administered questionnaire survey was conducted among dental hygiene students in a metropolitan area from July 21 to July 31, 2020, and finally, 196 copies were statistically analyzed using SPSS 21.0. Results: The mean values of mental health, academic self-efficacy, and test anxiety among the dental hygiene students were 1.47±0.41, 2.99±0.46, and 2.76±0.74, respectively. Mental health was negatively correlated with self-efficacy (r=-0.346, p<0.01) and positively correlated with test anxiety (r=0.405, p<0.01), while academic self-efficacy was negatively correlated with test anxiety (r=-0.424, p<0.001). The factors that affect test anxiety were somatization (p<0.05), anxiety (p<0.05), paranoia (p<0.05), task preference (p<0.05), and confidence (p<0.001), which are the detailed items of academic self-efficacy. Conclusions: It is necessary to develop and apply customized health programs suitable for individual students to improve their mental health, as well as develop teaching and learning methods that can improve academic selfefficacy, as mental health and academic self-efficacy are influential factors in test anxiety among dental hygiene students.

This paper proposes a built-in self-test tchnique for CMOS circuits. To detect a stuck-open fault in CMOS circuits, two consequent test patterns is required. The ordered pairs of test patterns for stuck-open faults are generated by feedback shift registers of extended length. A nonlinear feedback shift register is designed by the merging method and reordering algorithms of test patterns proposed in this paper. And a new multifunctional BILBO (Built-In Logic Block Observer) is designed to perform both test pattern generation and signature analysis efficiently.

This study analyzed the relationship between mother-child communication and the self-concept of young children. The subjects were 93 three-, four-, and five-year-old kindergarten children and their mothers in the city of Chunju. The self-concept test, mother-child communication inventory for children and the mother-child communication questionnaire for mothers were used. The data were analyzed by T-test, General Linear Models analysis, Duncan's Multiple Range test, Paired T-test, and Pearson's correlation coefficient. The major findings were that (1) the children perceived mother-child communication more intensively than mothers, (2) the more positive communication the children perceived they had with their mothers, the higher their self-concept, (3) the self-concept of 5-year-olds was more highly correlated with perception about mother-child communication than the self-concept of the younger children, and (4) boys' self-concept was more highly correlated with perceived mother-child communication than girls'.

A maternity ward in a hospital in Seoul has an educational program for postpartal mothers since its opening, but evaluation on the program has not been done. This study was to find whether the educational program contributed to increase of knowledge and confidence of the post-partal mothers in the area of postpartal self-care and the newborn baby care or not. This study aimed at improvement of the educational program for posrpartal mothers and the newborn babies. Subjects were 40 primiparae who were admitted to the obstetric ward in a general hospitals in Seoul from August 20th to September 10th, 1995. Subjects were those who had no labor pain at the admission time, had no complications during labor and delivery, gave a birth to a healthy baby, and agreed to participate in this study. All subjects were well educated and were in well-to-do group. Most of them received antenatal care adequately. They were tested on knowledge and self-confidence in the area of postpartal self-care and infant care two times, one at the admission time and the other prior to discharge. After the first test, nurses in a maternity ward and nursery taught them on postpartal self-care and infant care. Education consisted of a 1 hour planned program and incident teachings done at bed side. Four tools were developed by authors based literature review. The test tool for knowledge of postpartal self-care consisted of 15 items which included the definition of postpartum, dangerous symptoms in postpartum, lochia, time to begin coitus, postpartum exercise, sitz-bath, and perineal care. The test tool for self-confidence in postpartal self-care included such items as emergency care on dangerous symptoms in postpartum, sexual life and contraception after postpartum, self-confidence in postpartum exercise and perineal care. The test tool for knowledge of newborn baby care consisted of 18 items which included bathing, umbilical cord care, vaccination, breast feeding, abnormal symptoms of neonate. The test tool for self confidence in the newborn baby care included umbilical cord care, vaccination, breast feeding, emergency care for baby. Analysis of demographic data were analyzed with calculation of percentage. Score differences between the first test and the second test were analyzed with paired t-test. SAS / PC (Release 6.04 for DOS) program are as follows. 1. Mothers' knowledge of postpartal self-care increased significantly after education (t=10.04, df=38, p=0.0001). 2. Mothers' self-confidence in postpartal self-care increased significantly after education (t=6.53, df=38, p=0.0001). 3. Mother's knowledge of the newborn abay care increased significantly after education (t=9.74, df=38, p=0.0001). 4. Mothers' self-confidence in the newborn baby care increased significantly after education(t=8.22, df=38, p=0.0001) Suggestions for further studies and nursing practice were as follows. 1. We suggest studies by randomized control-group pretest-posttest design or nonequivalent control group pretest-posttest design will be done. 2. We suggest follow-up studies to find if mothers's confidence will last or not after discharge. 3. We suggest general hospitals to establish a phone-counseling system.

The increased potential for the lifespan of a child with cancer is largely due to advances in drug treatment, radiation treatment, and surgical techniques. In this generation cancer has become associated with chronic illness. Therefore supportive nursing intervention for children with cancer is needed to promote normal growth and development. This study was designed to develop and test the supportive nursing intervention program for promoting body image and self-esteem of children with cancer The supportive nursing intervention program involved emotional, physical, informational, and social support. The subjects were 41 children with cancer(20 in intervention group, 21 in control group) in K city. Measurements were taken concerning body image and self-esteem from both groups during pre and post test The data were analyzed using Cronbach's alpha, x$^2$-test, paired t-test and t-test. The results were as follows : The intervention group had a more positive body image as measured by the Body Cathexis Scale (t＝2.436, p＝.020) and a more self esteem as measured by the Cpopersmith self-inventory (t＝2.768, p＝.009) than the control group at post test. According to this study, the supportive nursing intervention program was effective for promoting the body image and self-esteem of children with cancer. Repeated research is needed to develop a refined supportive nursing intervention program for children with chronic illness.

Purpose: This study was aimed to evaluate the effect of an internet community on knowledge, self-efficacy, and self-care behavior in workers with hypertension. Method: The research design used was a nonequivalent control group pre-test and post-test design. Sixty hypertensive workers participated in this study(Exp.=29, Cont.=31). The data was collected from the 3rd of November 2003 to the 27th of February 2004 using an interview with questionnaires. Information related to hypertension was provided on the internet community weekly and an e-mail newsletter was sent in order to increase participation in the internet community. We used a tool developed by Park Young-Im(1994) that measured knowledge related to hypertension and self-efficacy. A tool developed by Jung Mi-Young(2001) was used for self-care behavior. The collected data was analyzed with an $x^2-test$ and t-test using the SPSS WIN 10.0 program. Result: The internet community helped workers with hypertension to increase their knowledge related to hypertension, as well as increasing their self-efficacy and self-care behavior. Conclusion: An internet community could be applied as hypertensive nursing intervention.

Objectives: The purpose of the study was to investigate the appropriate management and implementation of the oral malodor prevention for the general people. Methods: A self-reported questionnaire was filled out by 420 subjects in Seoul and Gyeonggi Province from March to October, 2013. Except 19 copies, 401 copies were analyzed. The instrument of subjective oral malodor awareness and status was adapted from Yoon and Youn and partly modified. The questionnaire consisted of general characteristics(4 questions), oral malodor awareness(3 questions), oral malodor related characteristics(3 questions), self-diagnostic test of oral malodor(5 questions), and subjective oral malodor and health status(3 questions). Self-diagnostic test of oral malodor was score as yes(1 point) and no(0 point). The subjective oral malodor and health status scoring was done by Likert 5 scale. Cronbach alpha was 0.713 in the self-diagnostic test of oral malodor. Results: The self-recognition rate of oral malodor was 0.8%. When the level of oral malodor increased to 1 point, the self-test of oral malodor increased as the rate of 0.033(p<0.05). Conclusions: There existed no close correlation between subjective recognition of oral malodor and oral malodor self-test. Therefore, oral malodor should be measured by an expert counseling to make an accurate diagnosis. It is important to establish the appropriate oral malodor prevention program for the general people.

메모리반도체산업이 성장함에 따라 수요와 공급이 큰 폭으로 증가하고 있다. 그 중 플래시 메모리가 스마트폰, 테블릿PC, SoC(System on Chip)산업에 많이 사용되고 있다. 플래시 메모리는 NOR-형 플래시 메모리와 NAND-형 플래시 메모리로 나뉜다. NOR-형 플래시 메모리는 BIST(Built-In Self Test), BISR(Built-In Self Repair), BIRA(Built-In Redundancy Analysis) 등 많은 연구가 진행되었지만 NAND-형 플래시 메모리 BIST는 연구가 진행되지 않았다. 현재 NAND-형 플래시 메모리 패턴 테스트는 고가의 외부 테스트 장비를 사용하여 테스트를 수행하고 있다. NAND-형 플래시 메모리에서는 블록단위로 소거, 페이지 단위로 읽기, 쓰기 동작이 가능하기 때문에 자체 내장 테스트가 존재하지 않고 외부장비에 의존하고 있다. 고가의 외부 패턴 테스트 장비에 의존해서 테스트를 수행하던 NAND-형 플래시 메모리를 외부 패턴 테스트 장비 없이 패턴 테스트를 수행할 수 있도록 두 가지의 유한 상태 머신 기반 구조를 갖고 있는 BIST를 제안한다.

Objectives: The purpose of this study was to investigate the relationship among the factors of communication ability according to self-awareness and other-awareness in some dental hygiene students. Methods: A self-reported questionnaire was completed by 260 dental hygiene students in Gwangju and Jeonnam from June 14 to 28, 2016. After explanation of the purpose of the study, an informed consent was written by the students. The effect size was calculated by $G^*power$ 3.1 program. The study instruments comprised the general characteristics of the subjects, self-awareness, other-awareness, and communication ability. Data were analyzed by independent test, one way ANOVA, $Scheff{\acute{e}}$ test, stewise multiple regression test, and Pearson's correlation test using SPSS 18.0. Results: Communication ability had a significant positive correlation with self-awareness(r=0.427, p<0.001) and other-awareness (r=0.460, p<0.001). The higher level of self-awareness and other-awareness was proportional to communication ability. The influencing factors of communication ability included private self-awareness(${\beta}=0.227$), public self-awareness(${\beta}=0.170$), social anxiety(${\beta}=0.182$), and external other-awareness(${\beta}=0.282$). Conclusions: To improve the communication ability in the dental hygiene students, it is important to improve self-awareness and other-awareness. The implementation of communication skill in the curriculum will enhance the dental hygiene students competency.

This paper proposes the self test method for 16 point FFT processor with systolic array architecture. To test efficiently and solve the increased hardware problems due to built-in self test, we change the normal registers into Linear Feedback Shift Registers(LFSR). LFSR can be served as a test pattern generator or a signature analyzer during self test operation, while LFSR a ordering register or a accumulator during normal operation. From the results of logic simulation for 16 point FFT processor by YSLOG, the total time is estimated in about. 21.4 [us].
