Objectives: Chronic insomnia disorder is a common and one of the most distressing sleep disorders. This pilot study was conducted to compare the spatial function between insomnia disorder patients and good sleeping control. Methods: We enrolled the 22 patients with chronic insomnia during over one year who met the DSM-5 diagnostic criteria of insomnia disorder and 27 normal sleeping controls. The Cambridge Neuropsychological Test Automated Battery (CANTAB) has been performed to compare the spatial cognitive function between insomnia disorder patients and good sleeping controls. Results: The CANTAB results showed significant differences in the problems solved in minimum moves of Stockings of Cambridge test (t = -2.499, p = 0.017). The significant difference between two groups remained after controlling age, sex, and Beck Depression Index non-sleep scores (F = 5.631, p = 0.022). Conclusion: This study suggests that the patients with insomnia disorder have poor spatial planning function.

The system test was accomplished in delivery time for a suitable of various requirements at the software market. Especially, critical faults must be detected and removed for a close main functions and users against target system. In generally, proposed test methods are executed with a calendar time, not a competitive and effectiveness method as selective software testing. These methods are inapplicable to short term test or early system development stage. Moreover, it's accompanied by heavy cost. Overcoming of these problems, must attempted to new software test method role of core function in the system test. Selective software testing method is decided to mixing with the three-information such as a frequency, complexity of use scenario and fault impact. Using this information, searching a fatal error and usefully system test for an executed test scenario. In this paper, we have proposed new test method and verified testing results for the detection of critical faults or search a fatal errors with a system main function.

The effect of circumvaginal muscle(CVM) exercises to improve sexual function in married women has not been investigated by currently acceptable research methods, nor have appropriate instruments and techniques to carry out such investigation been available. The purpose of this research was to study the effect of CVM exercise on sexual function, and of measuring CVM function after CVM exercises. The research tools used were a modified Derogates Sexual Function Inventory questionnaire and a pressure sensitive intravaginal balloon device. This research was conducted in Kwangju-city and Chonnam province, Korea from July, 1994 to July, 1995. The research used a non-equivalent control pre-post test quasi-experimental design. Forty-five healthy married female volunteers, aged 30-58, and were randomly assigned by age using the matching fixed-length blocks to two groups. The experimental group consisted of 21 women who were assigned a 25-minute per day CVM home exercise program for six weeks. The control group of 24 women did not do the CVM home exercises. The CVM home exercise was developed by Dougherty(1989a) and adopted to Korea by Lee (1993). Data were analyzed by $x^{2-}$test, Paired t-test, Spearman product-moment correlation using SAS /P $C^+. The results are summarized as follows : 1. There were no significant differences in the characteristics of the subjects between the experimental and control groups before the CVM home exercises. 2. Hypothesis 1 that married women who participated in CVM home exercises would have higher mean scores on the sexual function(SF) than in those who did not participate in home exercise was supported. 3. Hypothesis 2 that married women who participated in CVM home exercises would have higher vaginal pressure on SF than in those who did not participate in home exercises was supported (mean maximum pressure, t＝－7.338, P＜.0001, peak maximum pressure, t＝－11.164, P＜.0001). 4. Hypothesis 3 that the more often(number of days) and the more frequent (numbers of time per day) that married women do CVM home exercise, the higher their mean scores on SF and vaginal pressures was supported（r＝0.233, P＜.01 ; r＝0.352, P＜.05）. A six week CVM home exercise program using a tape recording showed that SF can be improved. Results of this study showed that married women who exercise on a regular basis for six weeks improve their sexual function and increase the mean vaginal pressure and peak maximum pressure (tested by electronic monitor). In conclusion, CVM exercise is effective in increasing SF.SF.

The purpose of this study is to identify the mediating effects of family function in the relationship between depression and health promotion behavior among university students. Data were collected from December 1 to December 31, 2018 and the participants included 340 university students, who responded to the question regarding health promotion behavior, family function and depression. The data were analyzed by descriptive statistics, t-test, ANOVA, Spearman's correlation coefficients, and multiple regression, mediation regression analysis of Baron and Kenny using the SPSS/WIN 23.0 program. As a result, A negative correlation is found between health promotion behavior and depression (r=-.48, p<.001), and positive correlation is among family function (r=33, p<.001), negative correlation is found between depression and family function (r=-.45, p<.001). family function have a partial mediating effect on the relationship between depression and health promotion behavior (Sobel test: -2.53, p<.05). Results of this study suggest that it is important to manage family function to improve health promotion behavior caused by depression.

We designed an ALU(Airthmetic Logic Unit) with BIST(Built-In Self Test), which is suitable for 32-bit DSP RISC processors. We minimized the area of this ALU by allowing different operations to share several hardware blocks. Moreover, we applied DFT(Design for Testability) to ALU and offered Bist(Built-In Self-Test) function. BIST is composed of pattern generation and response analysis. We used the reseeding method and testability design for the high fault coverage. These techniques reduce the test length. Chip's reliability is improved by testing and the cost of testing system can be reduced.

In this paper we consider the problem of testing for structural changes in ARIMA models based on a cusum test. In particular, the proposed test procedure is applicable to testing for a change of the status of time series from stationarity to nonstationarity or vice versa. The idea is to transform the time series via differencing to make stationary time series. We propose a graphical method to identify the correct order of differencing.
