Coping resources may be a crucial aspect in single mothers' and their childrens' adjustment. Using a survey data collected from 275 pairs of single mothers and their children, this study investigated the perceived effects of economic resoures, family relational resources, and social support on positive changes of both mothers and their children. Results revealed that both mothers and their children perceived positive changes of themselves and their children(mothers) relatively high. The degrees of positive changes of mothers were influenced mostly by family relational resources. In the same token, the degrees of positive changes of children were also affected by family relational resources. Overall, the findings suggested the importance of relational resources in explaining the positive changes of single mothers and their children.

The purpose of this study was to explore predictors of positive changes in children with divorced parents and to demonstrate the structural path among the perceived experience of social discrimination, parenting difficulties, parent-child communication, and internet use of children that related to positive changes based on family incomes. The subjects for this study were 1,114 single parents from divorced families sourced from a study on the status of single-parent families in 2015. The results of this study by using the structural equation model of the moderating effect verification with family incomes and multi group analysis are as follows. First, single-parent's perceived experience of social discrimination turned had a significant positive effect on parenting difficulties( =.354) and children's internet use ( =.234). Single-parent's perceived parenting difficulties also had a significant positive effect on children's internet use ( =.440) but a significant negative effect on both parent-child communication( =.192) and positive changes of children( =.218). Interestingly, internet use of children demonstrated a significant negative effect on their positive changes. Second, parent-child communication, parenting difficulties, and children's internet use had a negative mediating effect with the relationship where single-parent's perceived experience of social discrimination had an effect on positive changes of children( =.167). Second, between the family groups based on family incomes, there was no statistically significant difference in the structural relationship. Based on these results, this study presented a practical proposal to help single parents not experience social discrimination and to help decrease the internet use of children to improve positive changes.

Objective: This study examines the effects of acupoint combination on NADPH-diaphorase and neuronal nitric oxide synthase(nNOS) in the brainstem of spontaneously hypertensive rats. Methods: The changes of NADPH-d-positive neurons using a histochemical method and the changes of nNOS-positive neurons using an immunohistochemical method were evaluated. The optical densities of NADPH-d-positive neurons and nNOS-positive neurons of the Choksamni(ST36) Umnungchon(SP9) groups were significantly increased in all brainstem areas as compared to the Choksamni and Choksamni Kokchi(LI11) groups and decreased, with the exeption of the nNOS-positive neurons in the superficial gray of superior colliculus, as compared to the normal group. Results: Our results demonstrated that electroacupuncture changes the activity in the NO system in the brainstem of SHR and the acupoint combination is one of the important parameters for this effect.

Background : Syncope was defined as transient loss of consciousness and postural tone. The mechanisms of changes in cerebral hemodynamics during syncope have not been fully evaluated. Transcranial Doppler Ultrasonography can continuously monitor the changes in cerebral hemodynamics during head-up tilt (HUT). TCD could reveal the different patterns of changes in cerebral hemodynamics during syncope. Syncope without hypotension or bradycardia could be detected by TCD. We investigated the changes in cerebral blood flow velocity during HUT using TCD in 33 patients with a history of recurrent syncope or presyncope of unknown origin. Methods & Results : The positive responses were defined as presyncope or syncope with hypotension, bradycardia, or both. During HUT without isoproterenol infusion, there were a $86{\pm}23%$ drop in DV and a $41{\pm}34%$ drop in SV in 5 patients with positive reponses, and mean changes in those were less than 10% in patients with negative reponses (p=.00, p=.00). During HUT with isoproterenol infusion, TCD showed a $80{\pm}18%$ drop in diastolic velocity in 14 patients with positive reponses, and a $47{\pm}10%$ drop in that in patients with negative reponses (p=.00), however the change in systolic velocity did not differ. TCD showed three patterns during positive responses; loss of all flow, loss of end diastolic flow, and a decrease in diastolic velocity. Loss of consciousness occurred in the patients with loss of all flow or end-diastolic flow during positive reponses. Conclusions : TCD shows different patterns of changes in cerebral hemodynamics during HUT. TCD can be used to investigate the pathophysiology of neurocardiogenic syncope.

The anomaly-detection algorithm based on negative selection of T cells is representative model among self-recognition methods and it has been applied to computer immune systems in recent years. In immune systems, T cells are produced through both positive and negative selection. Positive selection is the process used to determine a MHC receptor that recognizes self-molecules. Negative selection is the process used to determine an antigen receptor that recognizes antigen, or the nonself cell. In this paper, we propose a novel self-recognition algorithm based on the positive selection of T cells. We indicate the effectiveness of the proposed algorithm by change-detection simulation of some infected data obtained from cell changes and string changes in the self-file. We also compare the self-recognition algorithm based on positive selection with the anomaly-detection algorithm.

This study examines how mental health promotion programs based on positive psychology brings changes in pleasant life, engaged life and meaningful life. This research considers 15 programs featuring 178 students during one semester. Pre-and-post examination of psychological well-being, depression and optimism were conducted to identify changes before and after the program. 56 students (32%) showed positive changes in all 3 factors. 15 students among them were selected for an in-depth interview for a qualitative case study. As a result of the quantitative study, a mental health promotion program based on positive psychology showed statistically significant positive changes in the pre-and-post examinations of psychological well-being, depression and optimism. Mental health promotion programs based on positive psychology showed positive changes in mental, cognitive and behavior perspectives in the fields of pleasant life, engaged life and meaningful life of college students. Specifically, positive psychology and thinking programs influenced students to become more enthusiastic and active in pursuing a pleasant life. Secondly, positive psychology intervention concerning engaged life brought a recognition of higher 'self-acceptance'. Thirdly, each individual spent more time and effort to experience more satisfaction and accomplishments. Lastly, subjects showed greater optimism after the program. Through the searching gratitude program, study subjects expanded their appreciation of their relationships with others.

This study was undertaken to investigate the effects of electroacupuncture(EA) on Choksamni(ST36), a well-known acupuncture site, on nicotinamide adenine dinucleotide phosphate-diaphorase(NADPH-d), neuropeptide Y(NPY) and vasoactive intestinal peptide(VIP) in the cerebral cortex of spontaneously hypertensive rats(SHR). EA on Choksamni was applied using 2Hz electrical biphasic pulses of 10min, 3 times a week for a total of 10 sessions. Thereafter we evaluated changes in NADPH-d-positive neurons histochemically and changes in NPY and VIP-positive neurons immunohistochemically. The optical density of NADPH-d-positive neurons in the Choksamni group was significantly lower in all areas of the cerebral cortex than in the control group. However, the optical density of NPY-positive neurons in the Choksamni group was similar to that of the controls in most areas of the cerebral cortex, with the exception of the primary motor and visual cortices. The optical density of VIP-positive neurons in the Choksamni group was significantly decreased as compared to the control group in most areas of the cerebral cortex, with the exception of the cingulate cortex. The present results demonstrated that EA on Choksamni changes the activity of the NO system, and that stimulation at the same level, causes selective changes within the peptidergic system in the cerebral cortex of SHR.

The purpose of this study is to investigate and analysis effect of TENS with immunohistochemistry methode through changes of substance P in spinal using arthritis model after inducing inflammation. The changes of substance P induced at that time are compared with control which is not induced arthritis by means of counting. The effect of TENS (4Hz, $200{\mu}$, 20minutes) is also tested by observing changes of substance P in spinal dorsal horn after application on knee joint of rats which is arthritis model induced by kaolin and carrageenan. The results of this study were as follows: 1. Substance P immunoreactive positive neurons are increased in dorsal horn after inducting arthritis. 2. In arthritis group, Substance P immunoreactive positive neurons are progressively increased from the first to the third days. 3. Substance P immunoreactive positive neurons after applicating TENS on arthritis group are more decreased than only arthritis-induced group. 4. Substance P immunoreactive positive neurons were significantly decreased on the second days resulting from TENS application from the first to the third days. Therefore, TENS application is decrease Substance P immunoreactive positive neurons in spinal dorsal horn of rats induced arthritis. This decrease is considered as analgesic effect of TENS.

This study was conducted to evaluate changes in nutritional knowledge, attitudes, behavior intention and behavior in a sample of 27 insulin dependent diabetic students participating in diabetics' camp. Nutritional knowledge related to diabetes, attitudes toward diabetes treatment and behavior intention about dietary changes were tested before and after nutrition education. Six months after nutrition education, an open ended questionnaire about their actual behavior changes was mailed to all participants and 17 of them responded. Pre-and post-testing showed that nutrition education was effective in significant changes in knowledge and in promoting positive attitudes and behavior intention. Increases of knowledge were consistently the same regardless of sex, level of education, regularity of diet, and duration of disease. Compared to male students, female students showed more positive change in knowledge, attitudes and behavior intention. It also appeared that middle school students showed more positive improvement in knowledge, attitudes and behavior than elementary and high school students. A follow-up test showed that their actual behavior changes were not squared with their behavior intention. They pointed out difficulties in having proper amount of meals and snack and the conflict with school time schedule as the major reason for discordance. These findings suggest that nutrition education for diabetics can be effective to improve their knowledge, attitudes and behavior intention and understanding about barriers to behavior change is important for better compliance to the disease.
