벨마비는 원인이 명확하지 않은 급성 말초성 안면 신경마비로 주로 편측으로 나타난다. 일부에서는 완전히 회복되지 못하여 안면 근육의 불완전 마비, 구축 등의 후유증으로 인해 하악의 편측 변위 또는 편측 저작 습관 및 부조화가 나타나며, 따라서 만약 무치악 환자에서 총의치로 수복한다면 더욱 세심한 주의가 필요하다. 본 증례에서는 벨마비의 후유증과 불안정한 하악 운동으로 인해 술자에 의한 중심위 채득이 어려운 무치악 환자에서 고딕아치 묘기법으로 재현성 있는 중심위를 채득하고, 중심위와 환자의 습관적인 하악 기능 운동 범위 간의 자유도 부여를 위해 설측 교합을 이용하여 총의치를 제작함으로써 기능 및 심미적으로 양호한 결과를 얻었기에 보고하는 바이다. Bell's palsy is an acute-onset unilateral peripheral facial neuropathy. For patients with sequelae of facial paresis, the successful rehabilitation of fully edentulous arches is challenging. This case report described the treatment procedures and clinical considerations to fabricate complete dentures of a patient who showed unilateral displacement of mandible, unilateral chewing pattern and parafunctional jaw movement due to sequelae of Bell's palsy. Gothic arch tracing was used to record reproducible centric relation and lingualized occlusion was performed to provide freedom to move between centric relation and the patient's habitual functional area in fabricating satisfactory dentures in terms of function and esthetics.

본 연구는 일과 가정 간의 관계가 여성 근로자의 성과에 미치는 영향을 파악하여, 여성 근로자의 일과 가정의 원활한 관계 유지와 더불어 갈등 관계를 감소시킴으로써 일과 가정의 균형을 통해 여성 근로자의 근로생활의 질을 높이고 우수 여성인력의 효과적인 활용을 극대화 할수 있는 지원제도의 조절효과를 살펴보고자 하였다. 이를 위해 중소기업 사무직에 종사하는 850명의 여성 근로자를 대상으로 설문조사하였으며, 연구대상이 아닌 직종과 불성실한 응답을 제외하고 최종 500부를 실증분석에 활용하였고 분석결과는 다음과 같다. 첫째, 일과 가정 간 조화 관계는 여성근로자의 직무만족과 조직몰입에 유의한 정(+)의 영향을 미치는 것으로 분석되었다. 둘째, 일과 가정간 갈등 관계에 있어서는 직무만족에 부(-)의 영향을 미치지만, 조직몰입과는 유의한 영향관계가 없는 것으로 나타났다. 셋째, 일과 가정 간 관계와 성과를 조절하는 비업무적 지원제도의 조절효과에 대한 가설을 검증한 결과, 비업무적 지원제도의 조절효과가 있는 것으로 밝혀졌다. 요컨대, 본 연구에서는 여성근로자의 일과 가정 간 조화 관계의 중요성을 입증하였으며, 여성근로자의 일과 가정 간 갈등 관계를 최소화 할 수 있는 지원제도의 구축, 특히 비업무적 지원제도를 기업에서 시급히 마련해야 할 것으로 연구결과는 시사하고 있다. This study investigates the effects on the performance of women workers' work-family relationship. As reduced conflict with maintain a harmonious relationship between work and family of women workers, improving the quality of work of women workers, look into an effective support system for maximizing the effectiveness of women workers. The final sample size for this study was 500. The results were as follows. First, the harmonious relationship between work and family have significant positive effects on the job satisfaction and organizational commitment of women workers. This implies that companies should make an effort to maintain harmonious work-family relationship for women employees and can enhance individual atisfaction and ultimately lead to corporate performance. Second, according to the result of verifying the second hypothesis that conflictive work-family relationship will affect employees' satisfaction negatively, there was partial support. In other words, conflictive work-family relationship influenced job satisfaction negatively, but it showed no correlation with organizational commitment. This result suggests that it has direct relationship with the job that is being actually carried out and indirect relationship with the organization. Third, based on the result of verifying the hypothesis on the moderate effect of non-occupational supporting systems which proved to be partially moderate effect. In short, this study has proved the importance of women workers' work-family relationship. Furthermore, the study results imply that it is necessary to establish supporting systems to minimize women workers' conflictive work-family relationship. It is also particularly urgent for companies to make non-occupational supporting systems.

The objective of this study consists on clarifying what factors are influenced upon skin care behavior using fender's Health Promotion Model, widely used to anticipate practices of health care behavior for women with keen interest in skin care and then manifesting their correlations from July 1 to August 22, 1998, on 159 women interested in skin care. A subvariable included practice of skin care behavior and independent variables include general characteristics, health fitness, the level of agreement with the advantages of the perceived skin care behavior, the level of cognition of the necessity for skin care behavior The data collected processed with ANOVA and multiple regression analysis to clarify what factors among other independent variables have the most powerful effects upon skin care. The resultant findings were revealed, as follows : 1. In health care behavior among skin care behavior,'full ingestion of water' represented the highest value by 3.45 points, 2. The testees of this study had for the most part a higher level of cognition for the necessity for skin care behavior than for practice of skin care behavior. The more points they have for cognition of the necessity for skin care behavior, the more points they present for practice of skin care behavior. 3. From the perspective of the relationship between sociometic factors on the testees and their skin care behavior, the higher level married women were on (p<0.05) and the more points they have for economic status, the higher points were reflected . 4. The correlations between the testees' recognition or perception factors and points for practice of skin health state showed the higher points than the group who thought that they did not know their own skin health state (p<0.05). The higher the points of skin care fitness (p<0.0001), the higher the points of self-awareness (p<0.0001) 5. The factors that had the most powerful influence upon cognition and practice of women's skin care behavior were found, with statistical significance, to be adjustable factors such as age, smoking, drinking habit, economic status, etc. and points of cognition of the necessity for skin care behavior.

The purpose of this study was to determine the effects of high voltage pulsed current (HVPC) stimulation on wound healing. Thirty-four Sprague-Dawley adult female rats were assigned to experimental and control groups. Each rats were anesthetized with pentotal sodium, and a 10 mm full-thickness incision was made on the back. From 24 hours after surgery, the rats of experimental groups were stimulated with HVPC, $140{\mu}s$, 120 pps, 30-40 V for 30 minutes, daily. The rats were sacrified 2 days, 4 days and 6 days after stimulation, respectively. The skin was removed, and processed for light microscopic examination. The length of incisional wounds were measured by microcaliper, and nucleolar organizer regions were counted under light microscope. For the histological observations the specimens were stained with Hematoxylin and Eosin, Masson Trichrome, Gomori Reticulum and Ag-NOR. There was a significant decrease in the length of incisional wound in experimental group compared with control group at 6 days HVPC stimuation (p<0.05). In experimental group, wound were significant difference (p<0.01) between the duration of post surgery. The mean numbers of nucleolar organizer regions per nucleus were significantly increased in the experimental group at 6 days HVPC stimulation (p<0.05), and were significantly difference (p<0.01) between the duration of post surgery in experimental group. Histological examination of the wound site suggested a more rapid of epithelialization and collagen formation between experimental groups compared with control groups. The result may indicated that the HVPC with $140{\mu}s$, 120 pps, 30-40 V for 30 minutes promoted surgical wound healing in the rat.

A Case of Progressive Ductal Constriction in a Fetus

최은영,Mei-Hua Li,Chang Won Choi,Kyo Hoon Park,최정연 대한심장학회 2013 Korean Circulation Journal Vol.43 No.11

The ductus arteriosus is a normal and essential structure in fetal circulation. Since the introduction of fetal echocardiography, there have been reports of ductal constriction, many of which were related to maternal use of some medications. However, there have been some reports of idiopathic ductal constriction, which usually present in later gestation. Recently we experienced a case, which initially showed an S-shaped ductus with mild narrowing at 23 weeks and 27 weeks gestation and developed severe ductal constriction at 33 weeks. Soon after birth, ductus was searched for but no ductus was found in 2-D and color images. The neonate required mechanical ventilation with supplemental oxygen for 3 days. All echocardiographic abnormalities were normalized in 7 months. We report progressive ductal constriction in an S-shaped ductus and emphasize the importance of continuous follow up extending to the third trimester and even immediately after birth.
