본 연구는 다중역할을 수행하고 있는 중년 직장여성을 대상으로 일-가정 갈등, 사회적지지, 자기효능감, 삶의 의미 간의 관계를 파악하고자 하였다. 구체적으로 연구 대상자는 40세에서 60세 미만의 자녀가 있는 맞벌이 중년 직장여성들로서 총 202명의 자료가 최종 분석에 사용 되었다. 구조방정식 모형을 통해 자료를 분석하였는데, 분석결과 첫째, 중년 직장여성의 일-가정 갈등은 사회적지지, 자기효능감과 유의미한 관계를 맺고 있었으나, 삶의 의미와는 직접적인 유의미한 관계를 갖고 있지 않았다. 둘째, 사회적지지와 자기효능감은 일-가정 갈등과 삶의 의미 간의 관계에서 유의미한 완전매개효과를 보이는 것으로 나타났다. 따라서 중년 직장여성이 다중역할 수행에서 삶의 의미를 찾도록 도와주기 위해서는 사회적지지와 자기효능감을 높여줄 필요가 있다. 연구결과를 토대로 교육과 상담에의 논의점 및 제안점을 제시하였다. The purpose of our study was to identify a structural relationship between the work-family conflict, social support, self-effectiveness and the meaning of life among married female workers who are performing multiple roles. The subjects were middle-aged married working mothers aged 40 to 60, they taked care of at least one child and worked more 10 hours in a week. The 202 data were analyzed using a structural equation model. The analysis results showed in the lives of middle-aged married female workers as follows. First, the work-family conflict had direct effects on social support and self-effectiveness significantly. And the work-family conflict had no significant direct effect but significant indirect effect on the meaning of life. Second, social support and self-effectiveness had complete mediation effects in relation between the work-family conflict and the meaning of life. Therefore, to find the meaning of life for middle-aged married female workers, it is necessary to enhance their social support and self-effectiveness. Based on the results of the study, we suggested the discussion for education and counseling.

This study was conducted to investigate the repellent efficacy of essential oils (Origanum vulgare, Pimpinella anisum, and Tanacetum cinerariifolium) and four plant extracts (Agastache rugosa, Capsicum annuum, Citrus reticulata, and Ginkgo biloba) against Tribolium castaneum (adults and larvae) and Plodia interpunctella (larvae). Gas chromatography/mass spectrometry analysis revealed the presence of carvacrol, anethole, and jasmolin I as the predominant constituent in O. vulgare, P. anisum, and T. cinerariifolium, respectively. Furthermore, ethyl hexopyranoside, 9,12‐octadecadienoic acid, cyclopentanol, and 2‐cresol were identified in A. rugosa, C. annuum, C. reticulata, and G. biloba, respectively. The repellent efficacy of each essential oil, plant extract, and the combination of oils was evaluated using a specially designed cylinder trap for 120 h. Among the three oils, O. vulgare and T. cinerariifolium had greatest repellent efficacy against P. interpunctella larvae. T. cinerariifolium exhibited effective repellence against the adults and larvae of T. castaneum. Therefore, O. vulgare (O) and T. cinerariifolium (T) were selected for further investigation of combined effects. Two essential oils were mixed in three different ratios of OT1 (1:3), OT2 (1:1), and OT3 (3:1). The repellent efficacies of OT1 and OT2 against the adults of T. castaneum were significantly greater than that of OT3. OT1 was effective against the larvae of T. castaneum, whereas OT2 was effective against the larvae of P. interpunctella. OT1 enhanced the repellent efficacy by approximately five times against larvae of T. castaneum, compared with that of T. cinerariifolium. Overall, OT1 was selected as the best repellent substance against all the tested insects.

목적: Retinoic acid는 폐포 재생에 중요한 역할을 하는 것으로 알려져 있어서 미숙아의 기관지폐이형성중의 예방에 사용되고 있다. 기관지폐이형성중의 병태생리는 미숙한 폐의 내피세포와 외피세포의 세포자멸사를 일으킴과 관련이 있다. 이에 본 연구에서 VEGFR2 억제가 신생 폐에서 세포자멸사를 증가시키는지, 또 retinoic acid의 투여가 본 폐 발달 억제 동물모형에서 세포자멸사를 억제하는지 알아보고자 하였다. 방법: VEGFR2 억제제인 SU1498을 생후3일된 마우스에 주사하고, 폐포발달이 이루어지는 그 후 10일간 retinoic acid나 위약을 주사하였다. 형태학적인 분석을 하였고, 세표자멸사를 비교분석하기 위해서 TUNEL 염색과 Annexin V을 표지자로 FACS출 시행하였다. 자멸사한 세포를 확인하기 위해서 동일초점 현미경으로 분석하였다. 결과: SU1498를 주사한 마우스에서 폐포면적과 평균폐포용적이 의미 있게 감소하였다. 세포자멸사도 약 3배 의미 있게 증가하였다. 자멸사한 세포는 내피세포와 상피세포에 분포하였다. Retinoic acid를 주사한 약 50%의 세포자멸사가 감소하였고, 형태학적으로 정상에 가까운 폐포 발달이 유지되었다. 결론: VEGFR2 억제를 하면 내피세포와 상피세포의 세포자멸사가 증가되면서 폐 발달이 저해되었다. 이어서 retinoic acid를 주사하면 세포자멸사가 억제되어 폐 발달유지에 도움이 되었다. 이러한 retinoic acid에 의한 세포자멸사의 억제가 기관지폐이형성증 예방에 기여할 것으로 추정된다. Background: Retinoic acid is known to play a role in alveolar regeneration and is used in the prevention of bronchopulmonary dysplasia (BPD) in premature infants. Many factors involved in the pathogenesis of BPD induce apoptosis of the endothelium and epithelium of the premature lung. We hypothesized that VEGFR2 inhibition would increase apoptosis in the newborn lung and retinoic acid would decrease apoptosis in our model of inhibited lung growth. Material and Methods: SU1498, a VEGFR2 inhibitor or vehicle was given to three-day-old mice. Subsequent retinoic acid or vehicle injection was given for ten days for the duration of alveolarization. Morphometric analyses were performed. Apoptosis was assessed with TUNEL staining and Annexin V staining. Co-localization of apoptotic cells with endothelial and epithelial cells was performed. Results: SUI498 injection reduced alveolar surface area and mean alveolar volume in newborn mice. Apoptosis was increased by three-fold in SU1498 injected mice. Apoptotic cells co-localized to endothelial and epithelial cells. Retinoic acid significantly reduced the degree of apoptosis by 50% in SU1498 injected mice and maintained lung development. Conclusion: VEGFR2 inhibition caused an arrest in lung development accompanied by an increase in apoptosis of endothelial and epithelial cells of the neonatal lung in mice. Subsequent retinoic acid treatment reduced apoptosis and we speculate that retinoic acid may preserve lung growth in bronchopulmonary dysplasia by inhibiting apoptosis in the neonatal lung.

The purpose of this study is to identify effects of 12 weeks walking-resistance exercise and running-resistance exercise on body composition and appetite regulating hormones. Participants consist of 17 overweight women who are 40's and have higher than 30% of the percentage body fat. They are randomly divided into two groups; Walking and Resistance Group (WRG, n=9) and Running and Resistance Group (RRG, n=8). For the walking group, exercise intensity of walking is gradually increased by 50%-70% every 4 weeks. There are 4 exercise sessions a week. On the other hand, there are 4 exercise sessions provided for the running group. Each session lasts for 30 minutes. The exercise is performed with intensity of 60% HRmax, (from 1st to 4th week), 70% HRmax (from 5th to 8th week) and 75% HRmax (from 9th to 12th week). The common resistance exercises provided to both groups are Bench press, Lat pull-down, Leg extension, Triceps extension, Leg curl, Biceps curl, Calf raises and Sit-up, which are performed with 60-70% of 1RM. First, for the body composition, it is found that weight, BMI and percentage body fat of the WR group and the RR group are significantly decreased during the exercise period. Second, for appetite regulating hormones, leptin in both groups shows statistically significant decrease while ghrelin is significantly increased. According to the results of 12 weeks duration combined exercise for the Walking and Resistance Group and the Running and Resistance Group, it is shown that body composition has been positively changed and appetite regulating hormone are improved. Therefore, this study concludes that the combined exercise is effective to treatment of obesity.

Everyday, we use electricity from the moment we wake up to the moment we go to bed. Not only it is closely interlinked with our everyday lives, but electric power is also an indispensable source as it is literally the fuel for sustaining industrial and economic development. Against this backdrop, electrical accidents are hazards that not only impose an inconvenience to people, but can also become a disaster that causes substantial loss to a country. Many of factors simultaneously contribute to the occurrence of an electrical fire, but in this paper, we specifically conducted research on line-to-ground faults. As single line-to-ground faults occur the most frequently in the distribution system, we analyzed earth fault currents that occur from the single line-to-ground fault. Moreover, we used the Electro-Magnetic Transient Program(EMTP) to model and simulate OCR (Over Current Relay) during inverse time which can separate fault sections in the distribution system to prevent accidents from spreading into an electrical fire.

The study analyzed the physical and chemical properties of dry-torrefied (DT) and wet-torrefied (WT) biomass. Hemicellulose was mainly degraded by torrefaction, and the contents of glucan and lignin were relatively increased. The degradation rate of biomass was higher in WT (18.25%–23.13%) than in DT biomass (3.12%–3.83%), and it increased with increasing reaction time. Torrefaction improved the crystallinity of the biomass from 36.88% in the raw material to a maximum value of 60.97% in the biomass subjected to wet torrefaction for 30 min (WT-30). The thermal stability of torrefied biomass was improved in WT-10 (17.21%), WT-60 (15.38%), and DT-60 (8.74%) compared to that of the raw material (2.35%). The hydrophobicity and fine particle distribution of biomass were increa- sed by torrefaction, with the lowest water absorption (3.08%) and the highest distribution of fine particles (8.20%) being observed in WT-60 biomass.

Overlap syndrome is a disease that combines major features of more than one rheumatic disease in the same patient. A 58 year-old female who was diagnosed as rheumatoid arthritis (RA) developed skin thickening and dyspnea. Clinical and laboratory findings revealed that she was affected by systemic sclerosis (SSc) and interstitial lung disease. Finally, she was diagnosed as overlap syndrome consistent with RA combined with SSc. The authors report a case of RA-SSc overlap syndrome with relevant literatures.
