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.

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.

In this study, the piezoelectric energy harvester was investigated employing the pillar structure with the diameter size of 50~500 um. Usually, the aspect ratio between the height and diameter was related with the piezoelectric performance. High aspect ratio was showed the low electric noise and high piezoelectric properties than low aspect ratio. Therefore, we have selected the Su-8 photo-resist and modified lithography process to manufacture the pillar structure with height above the 250 ${\mu}m$. In this presentation, we will report the process and properties of micro pillar structure based on the PMN-PZT (Pb$(Mg_{1/3}Nb_{2/3})O_3$-PbZrTiO$_3$) materials.

수침목재의 凍結乾燥 처리시 최상의 결과를 얻기 위해서는 대상유물의 상태와 ᅳ致할 수 있는 처리약품의 선정, 적용농도, 含浸방법 등 최적의 조건을 찾아내는 것이 필요하다. 이러한 조건설정은 전처리실험을 통해서만 가능하다. 이번 실험은 대전 월평동 유적에서 출토된 소나무(Pinus densiflora S. et Z.)와 상수리나무(Quercus acutissima Carruth.) 2種의 수침목재를 대상으로 2단계 PEG처리법(2-Step; PEG#200→PEG#4000), Sorbitol처리법, PEG#200+PEG#4000처리법,Sorbitol+PEG#4000처리법 등 4가지 방법으로 전처리한 후 동결건조하고 値數安定化效果를 비교하였다. 실험결과 2-단계 PEG처리법은 소나무材의 경우 PEG#4000을 60% 농도로, 상수리나무材의 경우 PEG#4000을 40% 농도로 처리한 것이 치수안정화효과가 가장 좋았다. Sorbitol 만을 적용한 처리법은 40% 농도로 처리한 소나무재에서만 비교적 양호한 결과를 얻을 수 있었다. 그리고 Sorbitol, PEG#200+PEG#4000, Sorbitol+PEG#4000으로 처리한 상수리나무는 기대한 만큼의 치수안정화효과가 나타나지 않았다. To get the best result from vacuum freeze drying of water-logged wood, it is necessary for objects to find out the best conditions such as chemicals, appropriate concentration of solution, impregnation method and etc. Such best condition could be set up by pre-treatment experiments. Two kinds of wood(Pinus densiflora S. et Z. and Quercus acutissima Carruth) were pre-treated by four methods; 2-step PEG treatment(PEG #200-PEG #4000), sorbitol treatment, PEG #200+PEG#4000 treatment, and sorbitol+PEG#4000 treatment. After those pre-treatment, vacuum freeze-drying was undertaken. Then the effect of dimensional stability were compared. When using 2-step PEG treatment, a solution of 60% PEG#4000 got the best dimensional stability for pine and in case of the oak, a solution of 40% PEG#4000 got the best. Sorbitol treatment got rather good result for the pine only when applied with 40% solution of sorbitol. Sorbitol, PEG#200+PEG#4000 and sorbitol+PEG #4000 treatments to the oak didn't affect on dimensional stability sufficiently.

This paper argued that the contents and the marketing of 『Dae Jang Gum』 and examined a new direction of Korean Wave. Because 『Dae Jang Gum』 split the world market into a few sector and sells monopoly of televising, and it takes a fusion historical television drama genre and Confucian tradition, so it can win explosive popularity in China. Through this conclusion, we confirmed the facts that it is in very urgent need of develops the high quality of contents and cultivate the special marketing manpower. Also through the various social phenomena which happens in China, we can expect that it will raise its multiplier effects by one-source multi-use strategy and reach phase of feel Korea. For these, it have to make continuous cultural interchanges and intimate element with Korea.

A study has been conducted for the coagulation characteristics of suspended solids made up of kaolin using Al-based inorganic polymeric coagulants; PACS(Poly Aluminium Chloride silicate) and PASS (Poly Aluminium Silicate Sulfate). PACS was found to be superior to PASS in its coagulating ability almost two times as much. The variation of ζ-potential of suspended particles in the sign and magnitude was closely related to the turbidity removed behavior. For the application of two coagulant mixtures, the overall coagulating power was a function of the mixing ratio and, in case of sequential dosage of two coagulants, the entire coagulation feature was governed by the firstly dosed coagulant. When a same amount of coagulant was dosed in partition to the supernatant water of one time treated wastewater, the final turbidity of two time treated supernatant water showed a lower value compared with the case that all amount of coagulant was dosed at one time. The size of coagulum formed using PACS was larger than that using PASS and it was thought that the coagulum size was determined by the coagulating power of coagulant. Slow mixing time and rate were considered to be influential on the degree of turbidity removal, but not on the ζ-potential of particles. An appropriate temperature range was established for a better turbidity removal and beyond this range the turbidity increased as the temperature rised.

Craniofacial dysostosis is considered to be one of rarely observed syndromes characterized by premature closing of all cranial sutures. The first patient was a 4-year-old male infant who had been complaining of empyema. Clinical findings showed exophthalmos, hypertelorism and facial asymmetry. Conventional radiographs demonstrated abscence of cranial sutures and underdeveloped maxilla. CT scan demonstrated the digital impressions of the inner surface of the cranial vault, enlarged and depressed sella turcica. The second patient was a 2-year-old female infant who had been complaining of facial deformity. Clinical findings showed hypertelorism and underdeveloped maxilla. Radiographs showed premature synostosis of all cranial sutures, depressed and enlarged sella turcica, and hypoplastic maxilla. 3 years after operation, her look improved. However, resurgery may be considered to decreasing intracranial pressure and for correction of facial deformity. Two interesting cases showing ‘cloverleaf’ skulls were presented.
