Objective: This study aimed to examine the sequential dual mediating effects of cooperative competence and peer relationships in the effect of positive parenting on adolescent’ happiness. Methods: This study used data from the 2nd Panel Study on Korean Child Youth Panel Survey. Subjects in this study were 2,348 adolescents in the second grade of middle school at that time. Data were analyzed using descriptive statistics, one-way ANOVA, pearson correlation analysis, path analysis with the SPSS 25.0 and AMOS 23.0 program. Results: First, there were significant positive correlations among positive parenting, adolescent’ cooperative competence, peer relationships, and happiness. Second, positive parenting had a significant indirect effect on adolescents’ happiness through cooperative competence and peer relationships. Conclusions: This study is meaningful in that it examined the specific path of variables affecting adolescents’ happiness using large-scale data of the national level. Also, the results of this study suggest that positive parenting, cooperative competence, and peer relationships are important resources for adolescents’ happiness. Therefore, in order to improve adolescents’ happiness, it is necessary to develop a program using these variables.

Objectives : This study was conducted to investigate the effects of fixed-intensity and varied-intensity electroacupuncture in pain and sensory threshold concerning parameters―visual analogue scale(VAS), brief pain inventory(BPI) and quantitative sensory testing(QST), among chronic tension headache patients. Methods : Thirty patients with chronic tension headache were randomly assigned to three groups and received different kinds of electroacupuncture at ST36 and ST37. Group A received fixed-intensity electroacupuncture(fixed-EA), group B received varied-intensity electroacupuncture (varied-EA), and group C received only acupuncture treatment without electrical stimulation as a control group. The intervention was given three times per week, and continued in two weeks. All the experiments were conducted blindly. Results : Fixed-EA group showed a significant decrease of VAS and BPI compared to the baseline measurement, while both varied-EA and control group did not. Of the parameters of QST, subtraction of heat pain threshold(HPT) and cold pain threshold(CPT) slightly increased in all groups, but this was not significant. Conclusions : These results suggest that fixed-EA reduce pain and improve quality of life in patients with chronic tension headache and that acupuncture may regulate patient’s pain sensitivity through changing sensory threshold.

Due to the growth of the food processing industry. various kinds of packaging methods have been developed. One method in particular, the retort pouch, has been noted as an alternative to the canned and bottled products which have shown problems in both flexibility and feasibility. The retort pouch refers to the packaged products which are flexible and able to withstand the high pressurized temperature of retorting. Historical perspectives of retort pouch were reviewed in terms of the developmental process, production methodology, packaging materials, usage trends, as well as pros and cons. Based on the critical advantages over canned or frozen products, continued growth of retort pouch will be prospective with the continuous efforts in research and technology.

A flexible piezoelectric energy harvester(f-PEH) that converts tiny mechanical and vibrational energy resources into electric signals without any restraints is drawing attention as a self-powered source to operate flexible electronic systems. In particular, the nanocomposites-based f-PEHs fabricated by a simple and low-cost spin-coating method show a mechanically stable and high output performance compared to only piezoelectric polymers or perovskite thin films. Here, the non-piezoelectric polymer matrix of the nanocomposite-based f-PEH is replaced by a P(VDF-TrFE) piezoelectric polymer to improve the output performance generated from the f-PEH. The piezoelectric hybrid nanocomposite is produced by distributing the perovskite PZT nanoparticles inside the piezoelectric elastomer; subsequently, the piezoelectric hybrid material is spin-coated onto a thin metal substrate to achieve a nanocomposite-based f-PEH. A fabricated energy device after a two-step poling process shows a maximum output voltage of 9.4 V and a current of 160 nA under repeated mechanical bending. Finite element analysis(FEA) simulation results support the experimental results.

Purpose: The purpose of this study was to investigate of the effects of the mode of delivery on pelvic floor muscle function by examining bladder base movement and urinary incontinence. Methods: This study was conducted on 100 females who had delivered in the previous 3–8 months. There were 2 groups: 56 vaginal deliveries and 44 cesarean section deliveries. Prior to the study, a survey was conducted on the subjects’ general status, delivery mode, urinary incontinence, and physical activity. The groups could not be blinded due to scar tissue from the operations. The function of the pelvic floor muscle was observed with the bladder base movement using transabdominal ultrasound during pelvic floor contraction. To objectify and measure the subjective symptoms of subjects suffering from urinary incontinence, an incontinence quality of life (I-QoL) test was administered. Statistical analysis of the data was performed using SPSS version 20.0. An independent t-test was used to assess the statistical significance of pelvic floor muscle function between the 2 groups after delivery. Results: The movement of the bladder base in the pelvic floor muscle function was decreased in the vaginal delivery group, but the difference was not significant. Urinary incontinence was significantly increased in the vaginal delivery group. Conclusion: The function of the pelvic floor muscles was better in the cesarean section group and the incidence of urinary incontinence was relatively low in this group. Therefore, vaginal delivery requires more efforts to restore the function of the pelvic floor muscles than cesarean delivery.
