This study was to investigate the effect of the statistics education program for the test-free semester. Two tests of questionnaires were used after revising some items for the subjects and statistical contents covered according to the purpose of the study during the 2nd semester, 2016. one was for finding students' attitude toward statistics and the other for understanding my career exploration. The statistics education program was developed for 5 lesson units and was applied to two classes with 53 students of one middle school in Gyeonggi-province. The results showed that students' understanding on career exploration was improved especially, in self understanding, perceiving career world related to statistics, and economical & educational understanding in statistical career. Also, the three areas such as interest, value, and effort among five areas about students' statistical attitude which was measured by the attitude test revised from the previous study, were improved with statistical significance. Moreover, we analyzed the degree of students' satisfaction over the program. Most of students were satisfied with the program saying that "I could not believe it is over now. The time has gone so fast." or "My mentor(a pre-service teacher) helped me a lot." Therefore, the program for the test-free semester should include the contents for exploring future-career and relating to real life.

Objective : This study was designed to identify the effects on the time usage and quality of life of seniors with stroke by applying lifestyle redesign programs on the theoretical basis of the Occupational Balance. Method : A pretest-posttest control group design was conducted for a total of 40 stroke elderly people living in nursing homes(20 experimental and 20 control groups). Prior assessment was conducted for two weeks before the application of the lifestyle redesign program. For the next 10 weeks, the lifestyle redesign program was applied seven times a week. After that, a week of post-evaluation was conducted. The time usage for the subjects was analyzed by Life Time Survey Table of the National Statistical Office(2009) and life quality for them was analyzed by World Health Organization Quality of Life-BRIEF (WHOQOL-BRIEF). Result : The comparison of time usage before and after application of the program demonstrated that for the experimental group, rest and sleep(t=-4.89, p<.001), and leisure(t=-4.67, p<.00b1) showed significant differences. In addition, intergroup comparison results showed that there were also significant differences in rest and sleep(t=-2.24, p<.01) and leisure(t=3.57, p<.01). The comparison of life quality showed a significant difference between two groups(t=6.80, p<.001). If you look at the sub-area of quality of life, a significant difference was identified in physical health(t=6.08, p<.001), psychological health(t=5.21, p<.001), living environment area(t=3.60, p<.01). Conclusion : Lifestyle redesign program actually reduced the time usage for rest and sleep for elderly with stroke living in nursing homes, and increased the time for participating in leisure life resulting in improved quality of life.

Objectives : In this study, patients with tic disorders who visited an Oriental medicine clinic were examined for their demographic characteristics, characteristics of symptoms, relation to Attention-deficit Hyperactivity Disorder(ADHD) and peculiarity according to various variables such as motor and vocal tics. Methods : After surveying 292 patients who visited an Oriental medicine clinic with tic symptoms as main complaints for 17 months, SAS 9.1, a statistical program was used for statistical analysis. Results : 1. The BMI of male tic patients was significantly higher than female ones and it was similar to or higher than the normal group. 2. Patients who are eldest children were 1.7 times higher than those who are not eldest ones. 3. The most usual case of motor tics was the eye blink and the most one of vocal tics was a dry cough. 4. There was no significant difference between male and female patients for all symptoms of motor and vocal tics, but male patients had significantly more obsessions related to tics than female ones. 5. There was no significant difference in the age of initial occurrence of Transient tic disorder(TTD), Chronic tic disoder(CTD) and Tourette's disorder(TD). 6. For the general disorder of a tic and Conners' ADHD rating scale, there was no significance in TTD, CTD and TD. 7. 66% out of the total subjects of 197 cases were found to score more than 65 points in more than 1 items among 8 items such as the time, hearing, wrong alarm, mean response time and standard deviation in the response time, etc. of the ADHD diagnosis system(ADS). 8. The eye blink among motor tics was shown mainly by patients under 10 years old and the frown, movement of the head, shrug and movement of the arms were shown mainly by 11-19 years old patients. Conclusions : For the number, frequency, seriousness and inconvenience in life of tics, TD showed a significantly higher result than TTD and CTD.

The primary objective of this research was to investigate optimum manufacturing condition of thin composite panels composed of sawdust, polyethylene film and polypropylene net. At the study the experiment was designed to make thin board in which sawdust offers effectiveness as core composing material, polyethylene as adhesive with added urea resin, and polypropylene as stiffness and flexibility in the composition panel. 100 types of thin composite panels were manufactured according to press-lam and mat-forming process of various hot pressing conditions(pressure, temperature and time). They were tested and compared with control boards on bending properties(MOR, MOE, SPL, WML), internal bond strength, thickness swelling, linear expansion and water absorption. At the same time the visual inspections of each types of panels were accomplished. The physical and mechanical properties of composite types passed by visual inspection were analyzed by Tukey's studentized range test. From the statistical analysis, the optimum manufacturing condition of thin composite panels were selected. Compared with two manufacturing processes, mat-forming process performed better than press-lam process in all tested properties. The optimum manufacturing conditions resulted from the experiment and statistical analysis were able to determine as following: the press temperature was shown the most good result at 130$^{\circ}C$ in mat forming process and 140$^{\circ}C$ press lam process, the press time 4 min in both processes, but the press pressure was 25-10kg/$cm^2$ in mat forming and 15k/$cm^2$ press lam process.

This study is aimed to evaluate the effects of the educational program that is designed to help the patients of T.K.R.A. to improve their self-nursing ability. The research will show how well this program can contribute to raising of their adaptability of everyday life by decreasing the difficulties that the patients had before in their daily life. The sample persons for this research were 40 adult patients who had T.K.R.A. in our hospital, and the data were collected through the questionnaires which were given to them. For the surveying tool, Jette's scale was applied to measure the degree of uncomforting that the patients experienced in their daily life. The materials of report had been gathered from May 1st to December 10th. The collected data were analyzed with real numbers, percentage, average, the standard deviation, TorF test and Pearsons correlation. The results of this study can be summarized like follows: The survey of self-caring exercise part were processed with two groups containing experiment group and contrast group. The exercise which took the highest points in experiment group was repetition of stretching and bending knees with laid down position while taking a walk, repetition of stretching and bending knees with seated on chair position and repetition of stretching and bending knees with laid down position got high points in contrast group. There were distinctive differences in statistics between repetition of stretching and bending knees in laid down position and taking a walk. There was no significant statistical gap between the degrees of inconveniences of daily life that each two groups experienced when we compared the average of the two groups, but 12 out of 20 questions got considerable differences. According to common characters of self-caring, there was a distinctive gap in the group who left the hospital in 14days and the ones who spend more than 30 minutes with exercise. The patient group who left the hospital in fourteen days after T.K.R.A. spent more time doing self-caring exercise. In the relationship between common characters and the degree of difficulties of daily life, Exercising is effective and Spending more that 30 minutes for exercise showed visible differences. The patients who answered that exercise are effective and put more time for it experienced less pain in their everyday life. The data proved by Pearson's correlation showed the relationship between self- caring and the degree of pain of daily life. According to the result, the increasing of self-caring activities helped to down the degree of inconveniences of daily life. This data show that T.K.R.A. reduced self-caring exercise ability and daily life activities. Therefore, the medical staffs who would take care the T.K.R.A. patients should offer stable nursing through well scheduled and education materials for patients. It is also important to encourage the patients to participate to the exercise by showing them how exercise after T.K.R.A. The education program is expecting to guarantee not only the right of patients to get enough information but also effective result to decrease uncomfortable of daily life.

Due to the ever increasing life-span of human beings, the average woman is living well into her 70's. Henceforth, they spend at least one-third of their life after menopause. Climacteric encompasses the time preceding, during, and proceeding menopause : a transitional period of shifting from the period of being fertile to the period of senescence. In other words, this is the time at which they lose the ability to reproduce. Menopause can influence a woman's sexual life immensely due to the physiological, social, and psychological changes that occur during that period. In korea, where some women still live according to Confucian Culture in terms of sexology, nurses can play a vital role in the dissemination of sexual facts to women. This study was designed to clarity the characteristic and satisfaction of sexual life. This was done according to the classification of three types of climacteric women : pre-meno-pausal, menopausal, and post-menopausal. I studied 159 climacteric women between the ages of 45 & 59, living in or around the vicinity of Taegu City. This study utilized the investigative tools for sexual life patterns which were constructed with field experts' consultation and reference review by the author. The sexual satisfaction was translated from DSFI. The climacteric symptoms were invented by Kupperman, This research is descriptive. The data was collected between July 15, 1998 and October 14, 1998. Statistical analysis was performed using ANOVA and Pearson Correlations, and was computed with the SPSS program. The results obtained are summarized as follows; The frequency of sexual activity was highest in pre-menopause and declined after menopause. The frequency of genital caressing declined after menopause. The difference between the frequency of masturbation and coital pain was not significant according to the classification set forth in this experiment. Congruently, the frequency of orgasms declined after menopause. The mean satisfaction of sexual life is 27.1 years. The range of expected score is 9-45 years of age. Satisfaction was highest in the pre-menopausal group and proved to be statistically significant. Some of the general characteristics that affected the satisfaction a woman's sexual life in the climacteric stage during this project were ; age, income, satisfaction in younger pre-menopausal and the large income group than the other experimental groups. The climacteric symptoms were conversely correlated with the satisfaction in one's sexual life.

There have been many different theories on the etiology of temporomandibular disorders(TMDs). The objective of the study was to investigate the effects of occlusal fctors and recent life event changes as prediposing fctor on the development of temporomandibjlar disorders. To evaluate the above predisposing factor, the author used T-scan system(Tekscan Co. U.S.A.) for quantitative occlusal analysis, clinical examination for occlusal state and Social Readjustment Rating Scale(SRRS) for recent life event change units (LCU). 63 patients with TMDs and 57 patients with malocclusion presented at Wonkwang University Dental Hospital participated in this study. The subjects were grouped by Angle's classification and presence of absence of TMDs and parafunctional oral habits. Data gained with regard to contact number, contact force, contact time, occlusal state(number of total teeth and occluding teeth, overjet, overbite) and occlusal interferences (protrusive posterior contact, nonworking side interference, and RCP-ICP slide) and recent life event changes. The data were processed and analysed by SAS statistical package program, The results of this study were as follows : 1. There were no significant differences on both quantitative occlusal contact analysis and occlusal state between TMDs group and Angle's malocclusion group. Also, there were no differences among the Angle's classifications. But amount of overjet in TMDs group were more greater than that of malocclusion group. 2. There was no difference on protrusive posterior contact, and balancing contact between TMDs group and Angle's malocclusion group. Premature contact was more frequent in malocclusion group, but RCP-ICP slide was more frequent in TMDs group. And RCP-ICP slide was more freqent in Angle's class II malocclusion than Angle's I or III malocclusion. 3. Life changes units in TMDs group were higher than those in malocclusion group. And recent life change units in group with parafunctional oral habit were higher than those in group without parafunctional oral habits. Clenching was the most common habit among parafunctional oral habits.

$^1H$ NMR spectroscopy coupled with multivariate statistical analysis was used for the first time to investigate metabolic changes in musts during alcoholic fermentation and wines during ageing. Three Saccharomyces cerevisiae yeast strains (RC-212, KIV-1116 and KUBY-501) were also evaluated for their impacts on the metabolic changes in must and wine. Pattern recognition (PR) methods, including PCA, PLS-DA and OPLS-DA scores plots, showed clear differences for metabolites among musts or wines for each fermentation stage up to 6 months. Metabolites responsible for the differentiation were identified to valine, 2,3-butanediol (2,3-BD), pyruvate, succinate, proline, citrate, glycerol, malate, tartarate, glucose, N-methylnicotinic acid (NMNA), and polyphenol compounds. PCA scores plots showed continuous movements away from days 1 to 8 in all musts for all yeast strains, indicating continuous and active fermentation. During alcoholic fermentation, highest levels of 2,3-BD, succinate and glycerol were found in musts with the KIV-1116 strain, which showed the fastest fermentation or highest fermentative activity of the 3 strains, whereas the KUBY-501 strain showed the slowest fermentative activity. This study highlights the applicability of NMR-based metabolomics for monitoring wine fermentation and evaluating the fermentative characteristics of yeast strains.

Amphora Ehrenberg ex Kutzing sensu lato is a common and widespread benthic diatom genus with a taxonomy that has been under continual revision, particularly based on molecular analyses. Although Amphora species have been studied using modern microscopy in recent years, there has not been much progress on molecular characterization of the species, especially in Asia. In this study of Amphora, sampling was carried out from September 2009 to August 2010 in Korean coastal waters. The morphological and molecular characteristics of eight Amphora sensu lato were examined: Amphora marina, A. proteus, Halamphora costata, H. coffeaeformis, H. eunotia, H. holsatica, H. terroris, and Halamphora sp. Based on previous accounts, morphology suggested that A. marina and A. proteus belong to the subgenus Amphora Cleve, which have smooth girdle bands and rather coarse and very distinct areolae on the valve. The other species, H. coffeaeformis, H. costata, H. eunotia, H. holsatica, H. terroris, and Halamphora sp. belong to the subgenus Halamphora Cleve, which was recently elevated to generic status by Levkov 2009, have plicate girdle bands, puncta which do not form straight longitudinal lines, valves which have a narrow ventral portion and apices that are generally rostrate-capitate and recurved. In agreement with analysis based on morphological characteristics, phylogenetic analysis based on small subunit rDNA suggested that the eight Amphora sensu lato species were not a monophyletic group as the morphological classification. Also, the results of molecular work and statistical analysis on all these Amphora sensu lato combined with phylogenic analysis on our geographically representative samples give strong evidence that Halamphora Levkov is independent of Amphora Cleve. Furthermore, in this study, Amphora terroris was transferred Halamphora as Halamphora terroris (Ehrenberg) Wang comb. nov. and Amphora marina was recorded for the first time in Korea.

The purpose of this study is to identify the effects of adolescents' experience activity satisfaction on their life satisfaction, and verify the mediating effects of sense of community between the two factors. For this, analysis has been conducted using Korean Children and Youth Panel Study (KCYPS, Ed. 6). Analysis were performed using the SPSS 24.0 program to verify the mediating effect, and the Sobel test was performed to analyze the statistical significance of the mediating effect. First, it was analyzed that the experience activity satisfaction had a statistically significant positive (+) effect on sense of community. Second, it was found that the adolescents' experience activity satisfaction had a significant positive (+) effect on the life satisfaction. Third, it was confirmed that snse of community had a positive (+) effect on life satisfaction, and at the same time, it was found that adolescents' experience activity satisfaction had a significant positive (+) effect on life satisfaction, so sense of community had a partial mediating effect.
