Purpose : The purpose of this study is to report the effect of oriental treatments to postpartum depression Methods : We treated the patient who had postpartum depression and visited Joong-hwa oriental hospital. The patient in this case, 36-years-old female, was admitted for 15days(161th/May/2005-30th/May/2005) due to postpartum depression which was measured by EPDS(Edinburgh Postnatal Depression Scale) and BDI(Beck's depression Inventory). The symptoms of patient are insomnia, anxiety, palpitation, chest discomfort and depression. This patient was treated with Hominis Placenta Herbal acupuncture at CV4(Kwanwon, Guanyuan), CV6(Kihae, Qihai), B23(Shinsu, shenshu), GVl5(Amun, Yamen), herb medication, acupuncture, auricular acupuncture, moxa treatment, and so forth. Results : As a result, symptoms are remarkably alleviated. Conclusions : Hominis Placenta Herbal acupuncture is expected to have an effect on postpartum depression. After this, further approach and study on postpartum depression might be needed.

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.

Objectives : Prevalence of postpartum depressive disorders reaches approximately 10-15% of childbearing women. This preliminary study was intended to explore the relationships between postpartum depressive disorders and family adaptability and cohesion. Methods : Childbearing women(n=24) were assessed for risk factors for postpartum depression before and after childbirth prospectively. At gestational age between 36th and 40th week, the questionnaire about various factors before childbirth, Edinburgh postnatal depression scale(EPDS), Family adaptability-cohesion evaluation scale (FACES), and Beck anxiety inventory(BAI) were assessed. After childbirth, for the diagnosis of postpartum depressive disorders, a structured diagnostic interview according to MINI International Neuropsychiatric Interview was performed, furthermore, the questionnaire about various factors after childbirth, EPDS, and BAI were assessed at 4-6 weeks postpartum. Results : Among various factors and scales, family adaptability and cohesion, mood symptom and change during pregnancy were associated with postpartum depressive disorder in comparison with non-postpartum depressive disorder subjects. In addition, low family adaptability and cohesion and mood change during pregnancy were significantly associated factors with postpartum depressive disorder using logistic regression analysis. Conclusion : The results suggest the postpartum depressive disorder could be related with prenatal low family adaptability and cohesion. This preliminary study, however, includes only a few subjects, so that further large-sized study will be needed to replicate our results.

Objectives : Postpartum depression is known to occur in 10-15% of mothers. The concentration of cytokine varies depending on stress, depression, pregnancy and general medical conditions. We hypothesized that the concentration of cytokines may be related to reproduction and childbirth, and that women with postpartum depression would show alterations in cytokines levels. Methods : A total of 104 pregnant women were selected as subjects, and 60 non-pregnant women were selected as normal controls. Symptoms of depression were evaluated in the pregnant study subjects using the diagnostic criteria outlined in the Edinburgh Postnatal Depression Scale (EPDS). The pregnant subjects were divided into three groups perinatal non-depression controls (n=61), postpartum depression-recovery (n=18), and postpartum depression (n=25). Results : The plasma concentration of TGF-β1, IGF-1 was higher in the pregnant group than in non-pregnant controls (TGF-β1 ; p<0.01, IGF-1 ; p=0.026). At 24 weeks of pregnancy and 6 weeks of delivery, there were no significant differences in the plasma concentration of TGF-β1, IGF-1, β-NGF, IL-2, IL-4, IL-6, IFN-γ, TNF-α between the three groups. There was no statistically significant difference in all three groups during the course of depression in pregnant women. Conclusions : This study found significant difference in plasma cytokines concentrations between non-pregnant controls and perinatal non-depression controls.

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.

Purpose: This study aimed to elucidate the prevalence of breast feeding and maternal psychosocial predictors affecting the breast feeding practice at six months postpartum. Method: One hundred and sixty one mothers at six months postpartum were conveniently recruited in two public health center in Jeju-city. Subjects completed a well-structured questionnaire regarding the feeding types of the child, maternal self-esteem, the Edinburgh Postnatal Depression Scale (EPDS), husband support, and marital adjustment scale. The data was analyzed using the $X^2-test$, t-test, Pearson correlation coefficients, and logistic regression. Result: The prevalence of breast feeding at six months postpartum was 29.9%. Predictors of breast feeding practice identified by the logistic regression analysis include first feeding type after delivery, marital adjustment, readiness for maternal role and work state. Conclusion: The prevalence of breast feeding practice was lower than WHO desired at six months postpartum. Therefore, the findings support the need for breast feeding education including interventions focused on improving readiness for maternal role and marital adjustment.
