This study was conducted to examine primiparas' perception of delivery experience and identity as the mother("Myself as the Mother" and "My Baby") according to delivery methods such as normal delivery and cesarean section. The result of this study summarized as follows. 1. The primiparas' perception of delivery experience according to delivery methods showed that the primipars who had normally delivered perceives the delivery experience more positively than those by cesarean section(t=4.88, p=0.000). This fact supported hypothesis 1 that "the primiparas group by normal delivery should perceive the delivery experience more positively that by cesarean section." 2. The primiparas who had delivered by cesarean section were more positive in the SD-Self score than those who had normally delivered at the time when four weeks passed after delivered, and there was a significant difference(t=-4.21, p\0.000). Therefore, hypothesis 2-1 that "the primiparas group who had normally delivered should be more positive in the SD-Self 1-2 days and 4 weeks after delivery than one who delivered by cesarean section" was rejected. 3. It was shown that the primiparas who had delivered normally were more positive in the SD-Baby 1-2 days 4 weeks after delivery than those who delivered by cesarean section(after-delivery 1-2 days : t=3.10, p=0.002 and after-delivery 4 weeks : t=2.15, p=0.034). Based on this fact, hypothesis 2-2 that "the primiparas group who had delivered normally should be more positive in the SD-Baby 1-2days and 4 weeks after delivery than those who had delivered by cesarean section"was supported. 4. Primiparas who had delivered by cesarean section appeared to have a positive identity as the mother by showing a more significant difference (t=7.96, p=0.000) 4 weeks after delivery than 1-2 days after delivery. In conclusion, we see that primiparas' perception of delivery experience and identity as the mother were different according to delivery methods. Thus, it is required to devise a nursing in tervention strategy to expand support from the health care system and opportunities to provide pre. post-delivery programs so that primiparas can have a positive perception of delivery experience and a positive identity as the mother. Based on conclusion stated above, the following suggestions are made. 1. As this study compared the perception of delivery experience and identity as the mother between prmiparas who had delivered normally and ones who had delivered by cesarean section, the further study on comparison between multiparas who had delivered normally and ones who had delivered by cesarean section is needed. 2. According to the results of this study, longitudinal study is needed to examine the difference and change in the formation of maternal identity. 3. According to the result of this study, a study is also needed to determine interaction between time for maternal identity and delivery methods.

Purpose: Chronic spontaneous urticaria (CSU) in children is a common skin disorder, but its clinical course varies. We investigated the clinical course and associated factors for CSU treatment in children. Methods: A total of 107 children, diagnosed with CSU from 2001 to 2016 in Dong-A University Hospital, who had been followed up for more than 6 months after treatment, were enrolled. The laboratory findings, and clinical aspects and courses were retrospectively investigated by a medical record review. We divided the 152 patients into 3 groups according to the treatment modalities: group 1, 1 antihistamine; group 2, more than 2 kinds of antihistamines; and group 3, antihistamines plus leukotriene receptor antagonist. Results: The mean age of patients in group 3 was 3.4 years (range, 2.6-4.2 years), which was significantly lower than those at the other 2 group patients (P=0.01). The urticaria activity score (UAS) of group 3 (6.1 [5.7-6.6]) was significantly higher compared to those of the other 2 groups (P=0.01). The improvement rate of the condition in children with positive specific immunoglobulin E (sIgE) reactivity to food or inhalant allergens was significantly lower than that of children with negative sIgE reactivity (P=0.01). Sex, age, history of allergic diseases, disease duration, UAS, previous treatment, and treatment modality were not correlated with the symptom improvement rate. Conclusion: Younger children and those with higher UAS needed more medication to ensure the improvement in symptoms. Moreover, it took more time for the improvement in symptoms in children who were sensitized to food or inhalant allergens. (Allergy Asthma Respir Dis 2017;5:211-216)
공기중과 고온고수압환경하에서 CANDU Zr-2.5Nb 압력관의 DHCV 비교

Zr-2.5Nb Pressure tube was used in the distilled water under high temperature and pressure. However, the evaluation of DHCV for pressure tube was limited in the air until now. Therefore, it was necessary for DHCV both in the air and in the distilled water under high temperature and pressure to evaluate. In advance, new DHC equipment simulating the real operating condition in the distilled water under high temperature and pressure was developed and DHCV test was conducted by this equipment. The test was carried out under simulated condition using distilled water of 250℃, 86bar and this result was compared with that of DHCV in the air of 250℃. DHCV of the distilled water was ranged from 8.42×10?? to 9.92×10?? m/s and the average value was 9.01×10?? m/s. As compared with the air condition, it was found that the characteristics of DHCV was not affected by the distilled water of high temperature and pressure. In addition, DHC equipment for high temperature and pressure was satisfied with the reliable conditions such as sealing, temperature control and data acquisition.

본 연구는 조직감 및 기능성 면에서 우수한 식물성 대체육의 제조를 위하여 부원료로 버섯을 첨가한 압출성형 대체육의 품질 특성에 대하여 살펴보았다. 대체육의 원료는 분리대두단백 50%, 글루텐 40%, 옥수수 전분 10%를 섞은 것을 기본배합(base)으로 하였다. 버섯 첨가함량을 기본배합 대비 0, 4, 8, 12%로 한 총 네 개의 시료를 수분함량 55%, 스크루 속도 150 rpm, 바렐 온도를 170℃로 하여 냉각 사출구를 통해 20℃로 사출하였다. 압출성형 후 물리적 특성으로 경도, 탄성, 응집성, 씹힘성과 절단 강도, 조직잔사지수, 보수력을 측정하였고, 화학적 특성으로 수용성 질소지수, 단백질 소화율과 DPPH 라디칼 소거활성을 측정하였다. 버섯 첨가함량이 증가함에 따라 경도, 탄성, 응집성, 씹힘성과 절단 강도가 모두 증가하였으며, 조직잔사지수 역시 증가하였다. 반면에, 버섯 첨가함량이 증가할수록 보수력과 수용성 질소지수는 감소하였으며, 단백질 소화율도 다소 감소하였다. DPPH 라디칼 소거활성은 버섯 첨가함량의 증가에 따라 유의적인 증가를 나타내었다. 압출성형 대체육에 버섯의 첨가는 대체육의 조직감을 개선하고 항산화 기능성을 부여하는 유효한 공정임을 확인하였다. This study was conducted to investigate the effects of mushroom composition (0, 4, 8, and 12%) on the quality characteristics of an extruded meat analog. The meat analog blend was isolated soy protein, wheat gluten, and corn starch (50:40:10). The extrusion condition was set to 55% feed moisture, 170℃ barrel temperature, and 150 screw speed by high moisture extrusion using a twin-screw extruder equipped with a cooling die. The integrity index, hardness, cohesiveness, springiness, chewiness, and cutting strength of the meat analog increased with the increasing mushroom content, while its water holding capacity and nitrogen solubility index (NSI) decreased. The protein digestibility decreased with the increasing mushroom content, while the DPPH radical scavenging activity significantly increased. In conclusion, the incorporation of mushrooms into the investigated meat analog enhanced its texture and antioxidant level.
