Objectives: Since early developed measurement of Postpartum depression(PPD) doesn't reflect physical symptoms, we need to find out how PPD and related physical disorders are expressed in functional medical methods. The study was conducted to find out characteristics of 7 Zone diagnosis and postpartum physical symptoms on PPD. Methods: To 216 postpartum women who did normal delivery, we measured 7-zone-diagnosis Factor AA's height on 5th day and 15th day postpartum. And we surveyed EPDS and postpartum physical symptoms question on 15th day postpartum. Subjects were divided into normal and depression group by EPDS score. And we compared Factor AA's height between two groups and Factor AA's height change in each group. Results: In depression group, Factor AA's height was higher than normal group on 5th day and 15th day postpartum. In both groups Factor AA's height was decreased on 15th day compared to 5th day postpartum. In normal group 2, 6, 7 zone were significantly decreased and in depression group only 6 zone was significantly decreased. Conclusions: These results demonstrate that postpartum depression group has low recuperative power. And these can be judged by Factor AA's height change.

Purpose: This study aimed to identify the scores of postpartum depression(PPD) on the first day, 1st week, and 6th week after the delivery and to explore their related factors before and after delivery in postpartum women. Methods: With a survey design, 293 postpartum women were recruited from a postpartum unit, Ilsin Christian hospital in Pusan via convenience sampling and were followed at 1st week and 6th week in the outpatient clinic. Results: Results showed that the scores of PPD(EPDS score) were low at postpartum 1st day, 1st week and 6th week but prevalence of PPD(EPDS ${\geq}13$)was 3.1%at 1st day, 8.2%at 1st week and 7.5%at 6th week, respectively. The pre-delivery factors were experience of depression, and the post-delivery factors were baby's sex(1st day), no caregiver for baby(1st week), and no help and concern for taking care of baby from husband and family(1st day and 6th week). The greater satisfaction with becoming a mother and her life, and greater maternal attachment were related to lower level of PPD at the three time points. Conclusion: Regular screening for postpartum depression and supportive and informative education is needed for postpartum women visiting the outpatient clinic for follow-up.

Since sapphire single crystal is one of the materials that have excellent mechanical and optical properties, the single crystal is widely used in various fields, and the demand for the use of substrate of LED devices is increasing rapidly. However, crystal defects such as dislocations and stacking faults worsen the properties of the single crystal intensely. When sapphire wafer of single crystal is used as LED substrate, especially, crystal defects have a strong influence on the characteristics of a film deposited on the wafer. In such a case quantitative assessment of the defects is essential, and the evaluation technique is now becoming one of the most important factors in commercialization of sapphire wafer. Wet etching is comparatively easy and accurate method to estimate dislocation density of single crystal because etching reaction primarily takes place where dislocations reached crystal surface which are chemically weak points, and produces etch pit. In the present study, the formation behavior of etch pits and etching time dependence were studied systematically. Etch pit density(EPD) analysis using optical microscope was also conducted and measurement uncertainty of EPD was studied to confirm the reliability of the results. EPDs and measurement uncertainties for 4 inch sapphire wafers were analyzed in terms of 5 and 21 points EPD readings. EPDs and measurement uncertainties in terms of 5 points readings for 4 inch wafers were compared by 2 organizations. We found that the average EPD value in terms of 5 points readings for a 4 inch sapphire wafer may represent the EPD value of the wafer.

Occurrence of epiphytic dinoflagellates (EPDs) in coastal waters off Jeju was first reported in 2011 based on 45 substrate samples from 24 macroalgal species. When re-analyzing, the extreme heterogeneous distribution of whole and genus-specific EPDs was reconfirmed across the sampling stations and substrate macroalgal species, as well as even across substrate samples of the same species. Abundance maximum of an EPD genus (cells g-wwt^-1) at a fixed surface-to-volume ratio (SA/V ratio) of the macroalgal species increased as the SA/V ratio increased up to 500 (cm² cm^-3). However, the abundance maximum of Ostreopsis further increased even in the MG2 (morphological group 2) macroalgae with the SA/V ratios over 500. The number of substrate macroalgal species on the plane of the MG and sampling station was more or less evenly scattered than the average EPD abundance, which was primarily driven by Gambierdiscus and Ostreopsis. Of the total EPD abundance of the five stations, 90.6% were represented by the two most common and abundant genera, Gambierdiscus and Ostreopsis, each accounting for 41.6% and 49.0%. Spatially, 95.9% of the total EPD abundance was found in St. 4 and St. 5, of which St. 4 with higher water temperature had more Ostreopsis spp. (31.8%), and St. 5 with higher salinity had more Gambierdiscus spp. (27.3%). Thus, the environmental transition to favorable T-S condition to MG2, the thin filamentous macroalgal group with very high SA/V ratios, is thus likely to support further success in EPD genera led by Ostreopsis in the coastal waters of Jeju.

Background: This study aimed to investigate the effects of combining the lumbar stabilization exercise with the gluteal muscle strength exercise on pain, the dysfunction index, and postnatal depression in women experiencing chronic low back pain after a cesarean section. Methods: The study used a randomized design with two groups: one group (n=15) performed the lumbar stabilization exercise along with the gluteal muscle strength exercise, while the other group (n=15) only did the lumbar stabilization exercise. The intervention consisted of 30 minute exercise sessions, twice a week, for 6 weeks. The pain was assessed using the visual analog scale (VAS), the dysfunction index with the Oswestry disability index (ODI), and postnatal depression using the edinburgh postnatal depression scale-Korean version (EPDS-K). Results: Both groups showed significant improvements in their VAS, ODI, and EPDS-K scores within their respective groups (p<.05). Additionally, the between-group analysis revealed significant differences in post-test results (p<.05). Conclusion: The combination of the lumbar stabilization exercise and the gluteal muscle strength exercise proved to be more effective in reducing pain, improving the dysfunction index, and alleviating postnatal depression in women with chronic low back pain after a cesarean section. Therefore, incorporating these exercises could be beneficial as an intervention program for women experiencing chronic low back pain after a cesarean section.

연구목적 산후우울증은 일반적으로 산모의 10~15%에서 발병하는 질환으로 그 원인으로는 정신사회적인 요인과 산과적인 요인이 모두 관계 있다고 알려져 있다. 감염, 손상, 악성종양, 자가면역질환, 스트레스에 의해 면역체계가 자극되면 proinflammatory cytokine과 anti-inflammatory cytokine이 생성되고 분비된다고 알려져 있다. 본 연구에서는 산후우울증이 있는 경우 산후우울증이 없는 군에 비해 혈중 Transforming growth factor-β1(TGF-β1), Insulin-like growth factor-1 (IGF-1), β-Nerve growth factor (β-NGF), Interleukin-2 (IL-2), IL-4, IL-6, Tumor necrosis factor-α (TNF-α), Interferon-γ (IFN-γ)의 농도가 상승되어 있을 것이라 가정하고, 임산부에서의 우울증의 경과에 따라 cytokine의 농도의 변화를 알아보고자 한다. 방 법 본 연구는 총 104 명의 임산부와 60명의 임신을 하지 않은 정상 대조군을 대상으로 하였다. 우울 증상은 임신 24주, 출산 1주, 출산 6주에 에딘버러 산후 우울 척도(EPDS)를 사용하여 평가하였다. EPDS의 총 점수가 10 이상인 경우, 우울증상이 있는 것으로 판단하였으며 EPDS 점수 변화에 따라 임산부 정상대조군, 출산 후 우울-회복군, 출산 후 우울군 세 그룹으로 나누었다. 결 과 임신군과 비임신 정상대조군을 비교하였을 때 TGF-β1, IGF-1의 혈장 농도는 임신군에서 비임신 정상대조군보다 더 높았다(TGF-β1 ; p<0.01, IGF-1 ; p=0.026). 그러나 β-NGF, IL-2, IL-4, IL-6, IFN-γ, TNF-α는 비임신 여성대조군에 비해 임산부 정상대조군에서 그 농도가 낮게 측정되었다(β-NGF ; p=0.001, IL-2 ; p<0.01, IL-4 ; p<0.01, IL-6 ; p<0.01, IFN-γ ; p<0.01, TNF-α ; p<0.01) 임신 24주에 TGF-β1, IGF-1, β-NGF, IL-2, IL-4, IL-6, IFN-γ, TNF-α의 농도를 살펴보면 임산부 정상대조군, 출산 후 우울-회복군, 출산 후 우울군 세 군간에 유의한 차이가 없었으며 출산 6주에도 역시 유의한 차이가 관찰되지 않았다. 또한 임신 24주, 출산 6주에 시간에 따른 농도 차이를 비교해 보았을 때 세 군에서 모두 그 통계적으로 유의한 차이는 없었다. 결 론 본 연구는 비임신 정상대조군과 임신군간의 혈장 cytokine 농도에서 유의한 차이를 발견했으나 산후우울증군과 정상 임신대조군간의 혈장 cytokine 농도는 유의한 차이를 밝혀내지는 못했다.

Printing technologies were applied to fabricate a flexible organic thin-film transistor (OTFT) backplane for electrophoretic displays (EPDs). Various printing processes were adopted to maximize the figures of each layer of OTFT: screen printing combined with reverse offset printing for the gate electrodes and scan bus lines with Ag ink, inkjet for the source/drain electrodes with glycerol-doped Poly (3,4-ethylenedioxythiophene): Poly (styrenesulfonate) (PEDOT:PSS), inkjet for the semiconductor layer with Triisopropylsilylethynyl (TIPS)-pentacene, and screen printing for the pixel electrodes with Ag paste. A mobility of $0.44cm^2/V$ s was obtained, with an average standard deviation of 20%, from the 36 OTFTs taken from different backplane locations, which indicates high uniformity. An EPD laminated on an OTFT backplane with $190{\times}152$ pixels on an 8-in panel was successfully operated by displaying some patterns.
