This study aimed to examine the relationship between sexual communication and marital quality. Study data were collected from structured questionnaires completed by 695 married men and women aged in their 30s and 40s. The major results were as follows. For the interaction coordination and postsexual interaction, there were significant differences between men and women, in that men had more interaction coordination and postsexual interaction than women. The results show the stereotype of sexuality in Korean society that men should be more active, and assertive while women should be passive and dependent. For both men and women, those who had more dyadic sexual communication, more interaction coordination, and more postsexual interaction had a higher level of marital quality. That is, sexual communication can function significantly in increasing marital quality. The study results suggest the necessity of training to improve sexual communication skills. For example, in educational programs for couple enrichment, it will be useful to include skills such as expressing ones' desire, affect, and feelings explicitly.

The purpose of the present study was to examine if perception of visual coordination pattern is consistent with the prediction of the HKB model (Haken, Kelso, Bunz, 1985). In addition, this study aimed to see if an additional sensory information using a grid background stabilizes perception of coordination pattern. Participants joined one of two experimental groups, Normal background and Grid background, to participate the pattern recognition training session and the pattern judgment test session. Participants observed $0^{\circ}$, $18^{\circ}$, $36^{\circ}$, $54^{\circ}$, $72^{\circ}$, $90^{\circ}$, $108^{\circ}$, $126^{\circ}$, $144^{\circ}$, $162^{\circ}$, and $180^{\circ}$ coordination patterns characterized by two oscillating dots. The dots oscillated in 0.25 Hz for the pattern recognition training and in 0.5 Hz, 1 Hz, and 2 Hz for the pattern judgment test. Judgment score, absolute judgment error, and judgment stability out of the pattern judgment test were analyzed statistically. The landscape of pattern accuracy and stability data was "inverted-U" shape with slower oscillating frequency conditions. In the faster condition, the accuracy and stability of the judgment decreased with relative phase patterns near $180^{\circ}$. These findings consistent with the prediction of the HKB model. The grid as additional sensory information did not increase accuracy and stability in coordination perception.

Mitochondrial homeostasis is tightly regulated by two major processes: mitochondrial biogenesis and mitochondrial degradation by autophagy (mitophagy). Research in mitochondrial biogenesis in skeletal muscle in response to endurance exercise training has been well established, while the mechanisms regulating mitophagy and the relationship between mitochondrial biogenesis and degradation following endurance exercise training are not yet well defined. Studies have demonstrated that endurance exercise training increases the expression levels of mitochondrial biogenesis-, dynamics-, mitophagy-related genes in skeletal muscle. However, the increased levels of mitochondrial biogenesis marker proteins such as Cox IV and citrate synthase, by endurance exercise training were abolished when autophagy/mitophagy was inhibited in skeletal muscle. This suggests that both autophagy/mitophagy plays an important role in mitochondrial biogenesis/homeostasis and the coordination between the opposing processes may be important for skeletal muscle adaptation to endurance exercise training to improve metabolic function and endurance exercise performance. It is considered that endurance exercise training regulates each of these processes, mitochondrial biogenesis, fusion and fission events and autophagy/mitophagy, ensuring a relatively constant mitochondrial population. Exercise training may also have contributed to mitochondrial quality control which replaces old and/or unhealthy mitochondria with new and/or healthy ones in skeletal muscle. In this review paper, the molecular mechanisms regulating mitochondrial biogenesis and mitophagy and the coordination between the opposing processes is involved in the cellular adaptation to endurance exercise training in skeletal muscle will be discussed.

Astrocytes are the most abundant cells in the central nervous system that play roles in maintaining the blood-brain-barrier and in neural injury, including cerebral malaria, a severe complication of Plasmodium falciparum infection. Prostaglandin (PG) $D_2$ is abundantly produced in the brain and regulates the sleep response. Moreover, $PGD_2$ is a potential factor derived from P. falciparum within erythrocytes. Heme oxygenase-1 (HO-1) is catalyzing enzyme in heme breakdown process to release iron, carbon monoxide, and biliverdin/bilirubin, and may influence iron supply to the P. falciparum parasites. Here, we showed that treatment of a human astrocyte cell line, CCF-STTG1, with $PGD_2$ significantly increased the expression levels of HO-1 mRNA by RT-PCR. Western blot analysis showed that $PGD_2$ treatment increased the level of HO-1 protein, in a dose- and time-dependent manner. Thus, $PGD_2$ may be involved in the pathogenesis of cerebral malaria by inducing HO-1 expression in malaria patients.

Background: The purpose of this study was to find out the effect of trunk stabilization training on the self posture control efficacy, physical self-description and perception stress in high school students. Methods: 92 voluntary students (73 females, 19 males) participated in this study. They received trunk stabilization training for 40 minutes per day and a time per week during 6 weeks period. Trunk stabilization training was an approach of education in proper posture and coordination of movement. In the evaluation, the self posture control efficacy scale (SPCES) was used to measure the posture control efficacy, the physical self-description questionnaire (PSDQ) was used to measure the physical self description and the perception stress scale (PSS) was used to measure the stress. All measurement of each subject were measured before and after stabilization training. Results: The SPCES were significantly different before and after (p<.05). The PSDQ and PSS were no significantly different before and after (p>.05) but the means were increased slightly. Conclusion: Conclusionally these results suggest that the trunk stabilization training increased the self posture control efficacy and would give help to control Students themselves.

The practical apprenticeship training is important and takes part in one fourth of the curriculum in university(college) nursing education. The quality and quantity of practical training influence the quality of nursing student ability. This study have planed to find out actual condition of practical apprenticeship training for university(college) nursing education and develop the reform measure in Korea. The questionnaires were sent for directors of nursing department in university(college) and the directors of nursing in hospitals which were chosen by systemic sampling and have over 500 beds. The response rate was 48.4% in total. The results were as follow : 1. There were 2 kinds of training system ;subject training and comprehensive training. The comprehensive training was done frequently in college education. There were gaps of subject between the lecture and the practical training education for professor, part time lecturler and assitant. 2. There was the shortage of training fields especially in college education. 3. The training content by university(college) personnel were care conference, orientation, ward rounding. The content by hospital nursing pernnels were bedside nursing skills and nursing process application. The headnurse acted the important role in training education. For improving the actual condition of training apprenticeship in university(college) nursing education, it is necessary that the Ministry of Education should make the accreditation system on the preparation of training hospitals for university(college) nursing education. The Academy Society for Nursing Education can do the central and coordination role to improve the training apprenticeship for nursing education in Korea.

Background: Children with cerebral palsy (CP) have impaired postural control, but critically require the control of stability. Consequently, therapeutic interventions for enhancing postural control in children with CP have undergone extensive research. One intervention is sensorimotor training (SMT) using a Flexi-bar, but this has not previously been studied with respect to targeting trunk control in children with CP. Objects: This study was conducted to determine the effect of SMT using a Flexi-bar on postural balance and gait performance in children with CP. Methods: Three children with ambulatory spastic diplegia (SD) participated in the SMT program by using a Flexi-bar for forty minutes per day, three times a week, for six weeks. Outcome variables included the pediatric balance scale (PBS), trunk control movement scale (TCMS), 10 meter walking test (10MWT), and 3-dimensional movement coordination measurement. Results: The SMT provided no statistically significant improvement in PBS, TCMS, 10MWT, or 3-dimensional movement coordination measurement. However, positive changes were observed in individual outcomes, as balance and trunk control movement were improved. Conclusion: SMT using a Flexi-bar may be considered by clinicians as a potential intervention for increasing postural balance and performance in children with SD. Future studies are necessary to confirm the efficacy of Flexi-bar exercise in improving the functional activity of subjects with SD.

Singing requires exquisite coordination between the respiratory and phonatory system to efficiently control glottal airflow. Respiratory function and vocal aerodynamics were investigated in six female professional sopranos and in six female subjects without vocal training. All sopranos had more than 15 years of formal classic vocal training. Pulmonary function test data on simple pulmonary function, flow volume curve, static lung volumes, maximum inspiratory pressure(MIP), and maximum expiratory pressure(MEP) were obtained from all subjects. Vocal aerodynamic studies of maximum phonation time(MPT), phonation quotient, and mean glottal flow rates (MFR) were also measured in all subjects. Simple pulmonary function in professional sopranos was generally the same as that of other female subjects without vocal training. However, MIP and MEP showing respiratory muscle forces were significantly elevated in professional sopranos, compared to those of other female subjects without vocal training. Maximum phonation times and phonation quotient in sopranos are longer than those of other female subjects even though there were no differences in simple pulmonary function. High-pitched tones were made with significantly higher mean glottal flow rates(GFR) in normal subjects than low-pitched tones, whereas no changes in GFR were found in sopranos. The result indicated that sopranos demonstrated significant improvements in aerodynamic measures of GFR, maximum phonation time, suggesting an increase in glottal efficiency.

In this article, I were trying to analyze the listed manufacturing companies' trend of productivity and the corporate education & training effect after the financial crisis. According to the analysis, the listed manufacturing companies have decreased their productivity since financial crisis, and from such declining trend. jobless growth and a growth without physical and human capital investment has been observed. Furthermore, there is no efficient labor force coordination within the manufacturing industry; In order to analyze the effect of education & training investment on productivity more deeply, I have practiced the dynamic panel data analysis from constructing the micro panel data which consists of company level information 1997~2008. According to the consequences, dynamic panel data analysis solved the problem of the overestimating education & training effect fairly well.
