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.

본 연구의 목적은 상대적 위상을 이용한 시각적 협응 패턴의 지각이 조절변수의 변화에 따라 HKB 모델(Haken, Kelso, Bunz, 1985)의 예측에 따르는지 확인해 보는 것이었다. 또한 격자무늬 배경을 이용한 부가적인 시각 정보가 협응 패턴 분별의 정확성과 안정성을 향상시키는지 알아보았다. 피험자들은 일반 배경과 격자 배경 중 하나의 그룹에 속하여 패턴 지각 연습과 패턴 분별 시험을 하였다. 피험자들은 좌우로 이동하는 두 점 사이의 상대위상으로 정의된 $0^{\circ}$, $18^{\circ}$, $36^{\circ}$, $54^{\circ}$, $72^{\circ}$, $90^{\circ}$, $108^{\circ}$, $126^{\circ}$, $144^{\circ}$, $162^{\circ}$, $180^{\circ}$ 패턴을 관찰하였다. 패턴 지각 연습은 두 점의 진동 주기 0.25 Hz에서 시행되었고, 패턴 분별 시험은 0.5 Hz, 1 Hz, 2 Hz에서 시행되었다. 패턴 분별 시험에서 얻은 분별 점수, 절대 분별 오차, 분별 안정성 자료를 통계적으로 분석하였다. 분별의 정확성과 안정성은 진동 주기가 느릴 때는 "뒤집어진 U" 모양을 띄다가 진동 주기가 빨라짐에 따라 $180^{\circ}$ 상대위상 패턴에 가까운 패턴들에서 정확성과 안정성이 감소하였다. 이러한 발견은 협응 패턴의 지각적 분별 역학이 HKB 모델을 따름을 나타낸다. 부가적 환경 정보인 격자무늬가 협응 패턴 분별의 정확성과 안정성에 도움은 되지 못하였다.

미토콘드리아의 항상성은 미토콘드리아 생합성과 마이토파지(자가포식에 의한 미토콘드리아 분해)로 불리는 2가지 주요 과정들에 의해 정교하게 조절되고 있다. 지구성 운동 훈련에 반응하여 골격근에서 미토콘드리아 생합성에 관한 기전들은 잘 정립되어 있는 반면 지구성 운동 훈련 후 골격근의 마이토파지 조절 기전과 마이토파지와 미토콘드리아 생합성의 협응을 조절하는 기전은 아직 명확히 밝혀져 있지 않다. 최근 연구들에 의하면 지구성 운동 훈련은 골격근에서 미토콘드리아 생합성, 미토콘드리아 역동성, 미토콘드리아 분해와 관련된 유전인자들의 발현을 증가시킨다고 하였다. 하지만 골격근에서 자가포식이 억제되었을 경우, 지구성 운동 훈련에 의한 미토콘드리아 생합성과 관련된 지표들인 Cox IV와 citrate synthase의 증가는 상쇄되었다. 따라서 자가포식과 마이토파지는 골격근의 미토콘드리아 생합성에 중요한 역할을 하며 정반대되는 이 두 과정(이화 또는 동화작용)의 협응 과정이 지구성 운동 훈련에 반응하여 대사적 기능과 지구력 운동 수행능력을 향상시키는 것과 같은 골격근의 적응에 중요한 듯하다. 지구성 운동은 미토콘드리아의 일정한 숫자를 유지시키기 위해 미토콘드리아 생합성, 미토콘드리아의 융합과 분열, 자가포식/마이토 파지들의 각각의 과정들을 조절하는 것으로 여겨진다. 지구성 운동 훈련은 골격근에서 마이토파지를 활성화시켜 미토콘드리아 양과 질을 조절하여 늙고 건강하지 않은 미토콘드리아를 젊고 건강한 미토콘드리아로 교체시킬 수 있다. 이 총론에서 미토콘드리아 생합성과 마이토파지의 분자학적 기전과 서로 상반되는 이 두 과정간의 협응이 골격근의 지구성 훈련에 대한 세포적 적응에 관련한다는 내용이 논의될 것이다.

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.

본 연구는 외환위기 이후 상장제조기업의 생산성 추이 및 교육훈련효과를 분석하였다. 분석 결과, 외환위기 이후 상장제조기업은 시간이 흐를수록 저 생산성 국면에 빠지게 되었으며, 그 과정에서 상장제조기업의 고용 없는 성장, 물적 투자 없는 성장, 인적자본투자 없는 성장 현상이 관찰되었다. 그리고 생산성이 높은 기업의 고용비중이 늘고, 낮은 기업의 고용비중이 주는 효율적인 노동시장이 거의 작동하지 않았다. 또한 교육훈련이 생산성에 미치는 영향을 분석해 보기 위해 동적 패널 분석을 실시할 경우 교육훈련의 과소투자가 발생하고 있음에도 불구하고 교육훈련의 생산성에 대한 지나치게 높은 긍정적 효과가 나타나는 모순적 현상이 상당 부분 해결되었다.
