본 연구는 미취학 자녀를 둔 여성들이 경제활동을 중단하였다가 노동시장에 재진입하는 요인을 파악해보고자 하는데 그 목적을 두고 있다. 이를 위해 본 연구에서는 여성가족패널 1차년도와 2차년도 자료를 활용하였다. 연구의 대상은 미취학 자녀를 두고 있고 과거 경제활동 경험이 있는 여성으로써, 노동시장 재진입이 이루어진 집단과 노동시장에 이탈되어 있는 집단으로 구분하여 로짓분석을 수행하였다. 본 연구의 결과를 살펴보면, 교육수준, 가구소득, 취학자녀수와 자녀수의 변화, 부모동거여부, 일자리변화가 노동시장 재진입에 영향을 미치는 요인으로 작용하였다. 즉, 교육년수가 높을수록, 취학자녀의 수가 많을수록, 미취학 자녀수가 감소할수록, 부모세대와 동거할수록 미취학 자녀를 둔 여성의 노동시장 재진입의 가능성이 높았다. 또한 출산을 이유로 일자리의 변화가 있었던 집단인 경우에는 출산후 노동시장에 재진입할 가능성이 높으며, 가구 소득이 적을수록 노동시장 재진입의 가능성이 높았다. 본 연구에서 자녀양육부담 감소, 부모의 동거가 노동시장 재진입의 가능성을 높이지만, 보육시설이용, 육아휴직, 부성휴가와 같은 일-가족양립 제도의 측면이 노동시장 재진입에 있어 유의미하지 않게 나타나지 않은 점, 그리고 가구소득이 적을수록 노동시장 재진입이 높게 나타난 점은 현재의 일-가족양립을 위한 제도의 개선과 다양한 지원이 필요함을 시사하고 있는 결과라 하겠다. This study determines the factors influencing the reentry career interruptive women into the labor market. To achieve this goal, data from KLoWF(Korean Longitudinal Survey of Women & Families) was used in this study. The subjects of the study are women with preschool-aged children who have experienced labor participation in the past. In this study, Logistic regression analysys was used to analyze and compare the group of women who experienced reentry into the labor market the group of women who had left the labor market. The result show that the reentry of career interruptive women into the labor market is affected by the following major factors: education level, change in the number of children, living together with a parent, and change in employment. As the burden of caring for children decreases, the number of women reentry into the labor market increase because the major cause of women leaving the labor market is to care for their children. Child care service is important for the compatibility of job and family; therefore, child care system ought to be enforced. However, the effect of child care service and a child care system is insufficient to allow women to experience reentry into the labor market. Therefore, this study suggests that child care service and a child care system should be improved upon, and various supports of child care service and a child care system are necessary for the reentry of career interruptive women into the labor market.

N/A Background/Aims: The autonomic nervous system distributed throughout the stomach consists of adrenergic, cholinergic, and non-adrenergic, non-cholinergic (NANC) nerves. Of these, NANC nerve fibers are known to be distributed all throughout the gastrointestinal tract and they provide the main inhibitory nerve supply to the gut smooth muscle. NANC nerve is known to release neurotransrnitters such as nitric oxide (NO), adenosine 5-triphosphate (ATP) and vasoactive intestinal peptide (VIP). However, the effect produced by each of the NANC neurotransmitter depends on an animal species and parts of gastrointestinal tract. Therefore, this experiment applied electrical field stirnulation at the circular musc]e of a guinea pigs gastric fundus to observe any relation of NANC nerve in muscu]ar relaxation. Methods: The effect of ATP, VIP, and NO on muscle re)axation was determined through the electrical field stimulation, and each neurotrans- mitters ability to regulate the muscle relaxation was compared. Results: Muscle strips were relaxed in response to electrical field stimulation that was applied. The relaxation was not inhibited by atropine or guanethidine, but was completely inhibited by tetrodotoxin. The muscle relaxation caused by NANC nerve stimulation was inhibited by L-NNA, VIP antagonist, and suramin. L-NNA was the most potent inhibitor among them. The muscle relaxation caused by electrical field stimulation was not further inhibited by VIP antagonist after the pretreatment of L-NNA, however, it was further inhibited by L-NNA following the treatment of VIP antagonist. The electrically stimulaed induced muscle relaxation was almost complete]y abolished by coadministration of L-NNA with VIP antagonist and suramin, The exogenous VIP-induced muscle relaxation was not affected by presence or absence of L-NNA. Oxyhemoglobin or methylene blue treatment inhibited the muscle relaxation induced by electrical field stimulation. Conclusions: Non-adrenergic and non-cholinergic nerve has an inhibitory neurotransmission in a guinea pigs gastric fundus circular muscle and NO is the principal inhibitory neurotransmitter of NANC nerve. NO mediated muscle relaxation is thought to be associated with increase of cGMP in muscle cells. (Korean J Gastroen- terol 1997;29:2S9 - 300)

Total excision is the treatment of choice of congenital melanocytic nevus. However, it is often infeasible, laser therapy is being explored as a useful therapeutic approach. A 26-year-old woman presented with a solitary, skin-colored plaque surrounded by whitish patches on her right calf. She was diagnosed with a congenital melanocytic nevus and underwent 84 laser treatment sessions using a 1,064 nm Nd:YAG laser over 7 years. Histopathological examination of the whitish plaque revealed small foci of nevus cells that penetrated the tissue to a depth that was 12-fold higher than the epidermal depth (1,260 μm). No report in the literature describes histopathological findings of a congenital melanocytic nevus treated with 84 sessions of laser therapy. This case report highlights the depth of penetration of pigment laser to treat a congenital melanocytic nevus. Our findings will serve as useful clinical guidelines to perform laser treatment for congenital melanocytic nevi. (Korean J Dermatol 2021;59(6):474∼476)

무장헬기는 대 기갑 작전, 공중강습 작전 엄호, 수색 및 정찰을 위한 항공지원업무 등 다양한 임무를 수행한다. 대부분의 무장헬기의 경우 Tandem식의 조종 방식을 가지고 있지만 Side-by-Side 방식의 헬기 또한 개발되고 있다. 이러한 현재의 추세를 볼 때, 공격전용 헬기의 Tandem식의 임무절차가 아니라 Side-by-Side 헬기에 최적화 된 임무절차와 이에 따른 임무하중에 대한 연구가 필요하다. 본 연구에서는 이러한 절차를 분석하기 위한 헬기 시뮬레이터를 구축하고, 주요 헬기 임무 절차를 선별하여 실험계획법에 따라 여러 대안을 평가하였다. 평가를 위한 데이터는 임무수행시간 측정 데이터와 NASA-TLX를 기법으로 정/부조종사 임무하중을 측정한 데이터로, 각 데이터들의 상자그림과 데이터의 평균 및 분산을 살펴보아 어떤 임무절차의 대안이 효과적이고 공통적인 임무로는 무엇이 가능한지를 분석하였다. 이를 통해 임무효과에 최적화 된 임무수행절차를 수립하는 것에 목적을 두었다. Armed helicopter is an integral part of armed forces, which conducts vital missions, such as anti-armor attack, close air support, escorting air assault operations, and reconnaissance. A typical cockpit arrangement of armed helicopters has been a tandem configuration. This is to reduce the frontal area, which in turn increases the forward speed as well as reduces the chance of being hit by enemy fires. However, many armed helicopters in the world are now being developed as a side-by-side configuration. Such configuration is quite different from the conventional cockpit arrangement in light of the crew communications and situational awareness. Therefore, the main objective of this study is to find the optimized combination of mission tasks among pilots in a side-by-side configuration cockpit by measuring the workload using the NASA Task Load Index method. The experimental results indicate that the workload of crew members differ as disparate tasks are being performed.

N/A The role of oxygen-derived free radicals has been studied in acute gastric and esophageal mucosal injury. Objectives: The aim of this study was to determine whether acid reflux causes oxidative stress in the esophageal mucosa and to investigate the correlation between mucosal glutathione (GSH) levels as an endogenous free radical scavenger and lipid peroxidation. Methods: Eight-week-old male Sprague-Dawley rats with a bodyweight of 250-300 g were used for the experiments. Acid reflux was caused by pyloric ligation. The sham operation included a midline laparotomy and served as controls. After 24 hr all rats were killed and esophageal samples were taken for measurement of gross mucosal injury and mucosal GSH level. Lipid peroxidation which is a marker of oxidative stress was determined by measuring the formation of thiobarbituric acid-reactive substances (TBARS) spectrophotometrically. Results: Severe mucosal damage was noted in reflux group. TBARS level was 6 times greater in reflux group compared to the control group (P<0.05), while GSH level was 4 times less in reflux group compared to the control group (P<0.05). Increase of TBARS level and decrease of GSH level showed a strong correlation to the gross findings of esophageal mucosal damage in reflux esophagitis. Conclusions: Oxygen-derived free radicals are of pathophysiologic importance in esophagitis caused by acid reflux. (Korean Journal of Gastrointestinal Motility 2001;7:175-180)

N/A Melanosis coli associated with ingestion of anthraquinone compounds in laxatives is due to accumulation of macrophages containing brown lipofuscin-like pigments in the lamina propria. We analyzed the clinical, endoscopic, and pathologic findings and colonic motor functions of melanosis coli and performed electronmicroscopic study to know the ultrastructural changes of neural elements. We studied 13 cases (mean age 48.1 +- 18.5 years, male to female cases 6:7). The vegetable laxatives containing anthraquinone derivatives, aloe or bisacodyl were used mainly and the mean duration of laxative abuse was l.5 +- 1.2 years. Endoscopically, dark brownish mucosal disoloration showed polyhedral forms divided by fine striae of lighter color. Melanosis was more intense in the more oral part of the bowel. Pathologically, no relationship was found between grade of melanosis and kind of drugs, daily dose, or durat.ion of addiction. Ultrastructural features on nerve structure were ballooning of axon. reduction of nerve specific cell organelles, and increased lysosomal activity. The alterations of these neural elements are assumed to he associated with impaired colonic motility. In conclusion, vegetable laxatives such as aloe, seem to be an important causes of melanosis coli in Korea. melanosis coli have a tendency to damage nerve fibers. We should avoid laxative abuse in order to prevent pragressing to cathartic colon.
