본 연구의 목적은 보건계열 대학생들에게 적용한 시뮬레이션 기반 연합프로그램이 자기효능감, 사회적 문제해결능력 및 대학생활 적응에 미치는 효과를 검증하고자 시도되었다. 본 연구 방법은 비동등성 대조군 전후설계의 유사 실험연구이다. 시뮬레이션 기반 연합프로그램에 참여한 실험군은 68명, 프로그램에 참여하지 않은 대조군은 68명이었다. 연구결과 자기효능감(z=-4.70, p<.001)과 대학생활 적응(t=2.03, p<.05)이 실험군에서만 유의한 향상이 확인되었다. 그러나 실험군과 대조군 간의 사회적 문제해결 능력(z=-1.87, p=.061)에는 차이가 없었다. 본 연구를 통해 시뮬레이션 기반 연합프로그램이 보건계열 대학생의 자기효능감과 대학생활 적응을 향상시키는데 효과적이라는 사실이 입증되었다. 따라서 사회적 문제해결 능력을 증진시키기 위한 효과적인 시뮬레이션 기반 연합프로그램이 개발되어야 하고 관련 연구가 더 필요할 것으로 제언한다.

In recent year, We are concerned in anti-aging, disease-protection, long-life, many method are used in solving this problem. Recently, We heard that Luffae Fructus Retinervus(LFR) has effect of anti-aging, disease-protection, long-life. So I let made a experiment for this result. The purpose of this study is to; 1) the anti-oxidant effect of Luffae Fructus Retinervus(LFR) used for 3 methods, those are DPPH radical scavenging activity, Nitric oxide(NO) radical scavenging activity, Superoxide anion radical scavenging activity, 2) cultivation 3T3-L 1 Preadipocytes and Protein chip used for ProteoPlexTM 16-Well Murine Cytokine Array Kit. We measured level of DPPH radical scavenging activity. And we experienced that the ability of DPPH radical's elimination was increased by rising concentration of LFR. When the concentration of LFR was 5 mg/ml, the ability of DPPH radical's elimination was Maximum. We measured level of Nitric oxide(NO) radical scavenging activity. And we founded that the ability of NO radical's elimination was significant when concentration of LFR was from 1.25 mg/ml to 2.5 mg/ml. We measured level of Superoxide anion radical scavenging activity. And we founded that the ability of Superoxide anion radical's elimination was maximum when concentration of LFR was 0.3125 mg. When we inspected Antioxidative Effects with BSA, we experienced that ability of defense was increased by rising concentration of LFR. We known the immunity of LFR about 3T3-L1 Preadipocytes and gained the increase of Cytokines(IL-2, IL-4, GM-CSF) without IL-12p70, $INF-{\gamma}$, $TNF-{\alpha}$ So I guess that Luffae Fructus Retinervus(LFR) has effects of anti-aging, disease-protection, long-life, etc.

Objective: Early environmental enrichment in life can improve cognition in animals. The effect of prenatal auditory stimulation on learning ability and fear level in chick embryos remained unexplored. Therefore, this study investigated the effect of prenatal auditory stimulation on the learning ability and fear level of chicks. Methods: A total of 450 fertilized eggs were randomly divided into 5 groups, including control group (C), low-sound intensity music group (LM), low-sound intensity noise group (LN), high-sound intensity noise group (HN) and high-sound intensity music group (HM). From the 10th day of embryonic development until hatching, group LM and group LN received 65 to 75 dB of music and noise stimulation. Group HN and group HM received 85 to 95 dB of noise and music stimulation, and group C received no additional sound. At the end of incubation, the one-trial passive avoidance learning (PAL) task and tonic immobility (TI) tests were carried out, and the serum corticosterone (CORT) and serotonin (5-HT) concentrations were determined. Results: The results showed that compared with the group C, 65 to 75 dB of music and noise stimulation did not affect the PAL avoidance rate (p>0.05), duration of TI (p>0.05) and the concentration of CORT (p>0.05) and 5-HT (p>0.05) in chicks. However, 85 to 95 dB of music and noise stimulation could reduce duration of TI (p<0.05) and the concentration of CORT (p<0.05), but no significant effect was observed on the concentration of 5-HT (p>0.05) and PAL avoidance rate (p>0.05). Conclusion: Therefore, the prenatal auditory stimulation of 85 to 95 dB can effectively reduce the fear level of chicks while it does not affect the learning ability.

There were no studies available measuring the ability to follow instructions for meditation. Hence, the present study was planned to assess the ability to follow instructions for the four mental states viz., cancalata (random thinking), ekagrata (non-meditative concentration), dharana (focused meditation) and dhyana (defocused meditation or effortless meditation) described in yoga texts. Sixty male volunteers with ages ranging from 18 to 31 years (group mean age ${\pm}$ S.D., $22.78{\pm}2.73$) participated in the study. They were assessed using a visual analog scale immediately after each of the four states on four different days. The results showed that following dharana, scores on the visual analog scale were significantly lower compared to those related to cancalata, ekagrata and dhyana. Hence, dharana is the most difficult of the four states.

The glycosaminoglycans (GAGs) present in the female reproductive tract promote sperm capacitation. When bovine sperm were exposed to 10 ${\mu}g/ml$ of one of four GAGs (Chondroitin sulfate, CS; Dermatan sulfate, DS; Hyaluronic acid, HA; Heparin, HP) for 5 h, the total motility (TM), straight-line velocity (VSL), and curvilinear velocity (VCL) were higher in the HP- or HA-treated sperm, relative to control and CS- or DS-treated sperm. HP and HA treatments increased the levels of capacitated and acrosome-reacted sperm over time, compared to other treatment groups (p<0.05). In addition, sperm exposed to HP or HA for 1 h before IVF exhibited significantly improved fertilizing ability, as assessed by 2 pronucleus (PN) formation and cleavage rates at d 2. Exposure to these GAGs also enhanced in vitro embryo development rates and embryo quality, and increased the ICM and total blastocyst cell numbers at d 8 after IVF (p<0.05). A real-time PCR analysis showed that the expression levels of pluripotency (Oct 4), cell growth (Glut 5), and anti-apoptosis (Bax inhibitor) genes were significantly higher in embryos derived from HA- or HP-treated sperm than in control or other treatment groups, while pro-apoptotic gene expression (caspase-3) was significantly lower in all GAG treatment groups (p<0.05). These results demonstrated that exposure of bovine sperm to HP or HA positively correlates with in vitro fertilizing ability, in vitro embryo developmental potential, and embryonic gene expression.

Purpose : The purpose of this research was to investigate the effects of barefoot walking on the sandy beach on pain intensity, disability, motor function, sleep satisfaction, and quality of life in the elderly with low back pain (LBP). Methods : A single-blinded randomized controlled trial was conducted involving 32 elderly with LBP who underwent sand walking barefoot (intervention, n=16) or with sneakers (control, n = 16). Both walking methods were carried out for 30 minutes per day, three times a week for four weeks. Pain intensity and disability were assessed using the visual analog scale and Oswestry disability index, respectively. Balance and gait were evaluated using the Berg balance scale and timed up and go test, respectively. Sleep satisfaction was quantified with the Verran and Snyder-Halpern sleep scale. Finally, quality of life was assessed through the WHO quality of life scale's abbreviated Korean version. Results : Compared with the control group, the intervention group showed significant differences in pain intensity (p=.005), disability due to LBP (p=.002), static balance ability (p=.003), dynamic balance ability (p=.002), and sleep satisfaction (p=.017). There was no significant difference in the quality of life between the two groups. Conclusion : Barefoot walking on a sandy beach is significantly effective in improving pain, disability due to LBP, balance ability, and sleep satisfaction in the elderly with LBP. Further studies with larger sample sizes and longer intervention periods must to be conducted to generalize using barefoot walking in LBP management.
