Purpose: The mode of transaction of agricultural products (vegetable) sold in the ‘Garak Agricultural and Marine Product Wholesale Market (GWM)’ can be distinguished into two types in terms of the distribution of agricultural products (Vegetable). First, it is the ‘Transaction of Unloaded Products (TUP)’ wherein the transaction and sales occurs on the vegetable unloaded from each transportation vehicle. Secondly, it is referred to as the ‘Transaction of Loaded Products (TLP)’ on each vehicle as it was loaded at respective places of production. Recently, the representative policy of distribution of vegetable was promoted and implemented in the ‘GWM’; the discussion to change conventional TLP into the TUP initiated since 2012, and the changed mode of transaction was started gradually with the loaded ‘Radish’ in April, 2017. The effect of change into TUP was investigated through varied approaches however substantial effect therefrom is yet to be identified through employing verified model thereof. Research design, data, and methodology: The present study thus intended to verify substantial effect of the improvement in distribution resulted from the initiation of TUP’ in the ‘GWM’ through identifying estimated costs of distribution before and after introduction of the TUP, and effect of the implementation thereof on receiving prices of vegetable of forwarders. For the estimation of the congestion and accumulation costs of distribution of vegetable to be sold by TUP, the transaction of ‘radish’, ‘onions’ and ‘Chonggak radish’, for which TUP from vehicles was introduced in 2017, were taken to compare the effect on distribution before (2016) and after (2017) the introduction of TUP. Results: The congestion and accumulation cost of distribution were also estimated wherefrom the daily distribution cost of ‘radish’, ‘onions’, and ‘Chonggak radish’ marked respective decreases of 9.852 million KRW for ‘radish’, 21.952 million KRW for ‘onions’, and 4.108 million KRW for ‘Chionggak radish’. Conclusions: Through conducting the present study, the substantial time cost saving effect of the improvement in distribution system of vegetable, resulted from the introduction of TUP, was verified positively. The outcomes of the present study are expected to be exploited for further studies, to be delving into detailed effects of implementation of the TUP, as basic data.

Jehovah's Witness comprise a unique obstetric population. Their refusal of blood stems from an interpretation of a literal translation of the Bible, and it is this belief that puts them at an increased risk of morbidity and mortality if hemorrhage occurs. We report two cases of a Jehovah's Witness who bled massively due to obstetric hemorrhage, refused blood transfusion and had profound anemia. The patients were treated with recombinant human erythropoietin, parenteral iron and oxygen. And they were treated on an intensive care unit with intermittent positive pressure ventilation. We reviewed with literature considering the therapy for acutely anemic patients who refuse transfusion to decrease the duration of the most severe anemia.

Purpose: Solitary fibrous tumor (SFT) is a rare tumor of the pleura, mediastinum, pericardium and other organs affecting predominantly middle-aged patients. SFT arising in the orbit is extremely rare, and its malignant form is even rarer. The authors herein describe a case of malignant solitary fibrous tumor of the orbit. Case summary: A 67-year-old male presented with a 4-month history of right proptosis. On ophthalmologic examination, 9-mm proptosis was observed in the right eye, and extraocular movements were limited in all directions of gaze. CT scan and MR imaging showed a lobulated, well-enhancing mass adjacent to the lateral rectus muscle in the superolateral retrobulbar space. Excisional biopsy through a lateral orbitotomy was performed. Histopathological examination showed proliferation of spindle cells with a fascicular pattern interspersed with bands of collagen, increased cellularity, cellular pleomorphism, hemorrhage, necrosis and high mitotic activity. Immunohistochemical staining revealed diffuse positivity for CD34, CD99, Ki67 and p53, and malignant SFT was diagnosed. Conclusions: Malignant SFT should be considered in the differential diagnosis of acutely progressing unilateral proptosis.

Purpose: The present study assessed the influence of overnight orthokeratology (ortho-k) on the myopic progression in Korean children and analyzed factors affecting myopic progression. Methods: The ortho-k group was comprised of 31 patients satisfying the inclusion criteria for ortho-k. In the ortho-k group, spherical equivalent refractive error (SER) was measured at baseline, and after 2 weeks, 6 and 12 months. The control group was comprised of 31 patients who were matched according to age, gender, and baseline SER of the ortho-k subjects. Results: In the ortho-k group, the mean ± SD changes in SER from 2 weeks to 6 months, 6 to 12 months, and 2 weeks to 12 months were -0.17 ± 0.50 D, -0.04 ± 0.76 D, and -0.21 ± 0.78 D, respectively. In the control group, the changes in SER from baseline to 6 months, 6 to 12 months, and baseline to 12 months were -0.38 ± 0.42 D, -0.44 ± 0.38 D, and -0.82 ± 0.68 D, respectively. Significant differences were found between changes in SER from 6 to 12 months and from baseline to 12 months (p < 0.05). In the ortho-k group, relationships between the changes of SER for 1 year and the numeric values of baseline measurements were analyzed. When comparing the results between the group of SER change ≥ -0.5 D with the group of SER change < -0.5 D, numeric values of white-to-white diameters of the 2 groups were different, and a significant correlation was found between the range of SER change and the white-to-white diameter (Pearson’s r = -0.471, p = 0.008). Conclusions: Ortho-k is effective for slowing myopic progression. The smaller the white-to-white diameter, the slower the myopic progression could be.

Purpose: To report cases of intraocular pressure that was normalized, after removing the capsule that had incarcerated into the valve after Ahmed valve implantation. Case summary: A 34-month-old boy visited our clinic for elevated intraocular pressure of the right eye. The patient had received Ahmed valve implantation 1 year earlier. At the first ophthalmological examination in our hospital, intraocular pressure of the right eye measured by Perkins tonometer was 28 mm Hg using Cosopt? and Iopidine?, and 26 mm Hg after additional digital massage; the authors decided to remove the capsule with surgery. The fibrotic tissue was removed after finding the tissue incarcerated into the valve during the operation. One day after the surgery, without using any glaucoma medication, intraocular pressure of the right eye measured by Perkins tonometer was 15 mm Hg. Three months after surgery, using topical intraocular pressure lowering agents, intraocular pressure of the right eye was 18 mm Hg. Because the intraocular pressure of other patients after Ahmed valve implantation was not regulated well, surgery was performed, and the fibrotic tissue was removed after finding the tissue incarcerated in the valve during the operation.

목적: 자궁동맥색전술은 산후출혈의 치료에 이미 보편적으로 이용되고 있다. 그러나 조기 및 후기 산후출혈에서 동맥조영술상의 차이가 있는지는 아직 잘 알려지지 않았다. 본 연구의 목적은 조기 및 후기 산후출혈에서 동맥조영술상의 차이가 있는지를 규명하고 자궁동맥색전술의 산후출혈의 치료효과를 확인하는 것이다. 연구 방법: 산후출혈로 동맥색전술을 시행받은 12명의 환자의 의무기록과 동맥조영술 사진을 후향적으로 분석하였다. 출혈시간, 분만방법, 치료효과, 동맥조영술 소견을 일차적 분석항목으로 정하였다. 결과: 12명 중 11명에서 초선택적 색전술로 효과적 지혈이 가능했다. 1명은 양수색전증과 범발성 혈관내응고로 사망하였다. 혈관조영술상 조기 산후출혈에서 자궁적출술을 받지 않은 5명 모두에서 자궁 크기가 커져있는 자궁이완증의 소견이 관찰되었고 후기 산후출혈에서는 5예 모두에서 거짓동맥류가 확인되었다. 결론: 초선택적 색전술은 효과적인 산후출혈의 치료법이다. 후기 산후출혈의 경우는 거짓동맥류가 중요한 원인으로 생각된다. Objective: Treatment of postpartum bleeding with uterine artery embolization has been well-described so far. However, angiographic differences between early and late postpartum bleeding has not been elucidated. The purpose of this study was to evaluate angiographic differences between early and late postpartum bleeding and therapeutic effect of superselective embolization. Methods: Medical records and angiographic images of 12 patients (7 early and 5 late) with postpartum bleeding were evaluated. Timing of bleeding, mode of delivery, angiographic findings and treatment outcome were primary variables evaluated. Results: Among 12 patients, 11 patients had been successfully treated with superselective embolization. One patient with amniotic fluid embolism and disseminated intravascular coagulation had expired. Among the early postpartum bleeding, uterine atony was found in every patients except post-cesarean hysterectomy cases. Pseudoaneurysm of uterine artery was found in all patients with late postpartum bleeding. Conclusion: Superselective embolization is an effective method to control postpartum bleeding. Pseudoaneurysm of uterine artery is a main cause of late postpartum bleeding.

본 연구의 주 목적은 ‘국어수업 중 10분 독서’ 활동이 중학교 1학년 학생들의 독서태도에 미치는 영향을 검증하는 데 있다. 이를 위해 ‘국어수업 중 10분 독서’ 활동을 프로그램 준비 단계, 적용 단계, 확인 단계로 구분하여 적용하였으며, 이를 통해 얻어진 결과는 다음과 같다. 첫째, ‘국어수업 중 10분 독서’ 활동은 중학생들의 독서태도에 영향을 미치는 것 으로 나타났다. 둘째, ‘국어수업 중 10분 독서’ 활동을 통해 형성된 독서 태도는 본 프로그램이 단기간이 아니라 장기간 지속적으로 운영될 때 일관성을 지닐 수 있음이 밝혀졌다. 셋째, 독서태도 형성 요인 가운데 가정 문식성, 학교 문식성, 타인의 기대에 대한 신념 등에서는 유의미한 변화가 없었지만 사회 문식성에서는 유의미한 차이를 보였다. 즉, ‘국어수업중 10분 독서’ 활동이 독서태도 형성 요인들 중 사회 문식성에는 긍정적 영향을 미치고 있다는 것이다. This study has the purpose of suggesting ‘10-minutes reading activities during Korean language class’ as a way to encourage reading attitude, one of the important purposes of reading education, and of presenting a concrete method to sustain the reading attitude by examining the effect on the reading attitude of the 1st year students in middle school. The conclusion from this study can be drawn as follows. First, the continuous ‘daily 10-minutes reading activities during class’ of Korean language class became a base of right reading attitude, and the reading attitude of the students who kept reading were improved more positively than those who stopped it midway. Second, considering the fact that it needs long-term efforts to form desirable reading attitude because the reading attitude is formed not in a short time or by temporary activities, but over a longer period, and if a variable having influenced on the reading attitude is removed, the reading attitude won’t last any more, the circumstances that can keep 10-minutes reading activities during Korean language class steadily should be prepared to hold the reading attitude once formed consistently, and if it is introduced in the curriculum of school, the scene of the school will be changed. Third, the 1st year students in middle school who are much influenced by peer group feel more interest in the books recommended by friends than those recommended by teachers, and their positive attitude for reading are formed in the course of having talks of books with friends. Reading in adolescence is very important because it may change a person’s life, so it needs to make the period of 10-minutes reading activities during class longer, and there needs to give much interest and make responses to have mutual relationship even though their grades go up. And, it needs to develop ‘10-minutes reading activities during class’ in the direction of contributing to formation of readings for lifelong reading.

김재령(Kim, Jae Ryoung),박진욱(Park, Jin Uk),이보현(Lee, Bohyun),이표(Lee, Pyo),이종철(Lee, Jong-Cheol),문상진(Moon, Sang-Jin) 한국신재생에너지학회 2010 한국신재생에너지학회 학술대회논문집 Vol.2010 No.06

We have fabricated organic photovoltaic cells (OPVs) with highly conductive poly 3,4-ethylenedioxythiophene : poly styrenesulfonate (PEDOT:PSS) layer as an anode without using transparent conducting oxide (TCO), which has been modified by adding some organic solvents like sorbitol (So), dimethyl sulfoxide (DMSO), N-methyl-pyrrolidone (NMP), dimethylformamide (DMF), and ethylene glycol (EG). The conductivity of PEDOT:PSS film modified with each additive was enhanced by three orders of magnitude. According to atomic force microscopy (AFM) study, conductivity enhancement might be related to better connections between the conducting PEDOT chains. TCO-free solar cells with modified PEDOT:PSS layer and the active layer composed of poly(3-hexylthiophene) (P3HT) and phenyl [6,6] C61 butyric acid methyl ester (PCBM) exhibited a comparable device performance to indium tin oxide (ITO) based organic solar cells. The power conversion efficiency (PCE) of the organic solar cells incorporating DMSO, So + DMSO and EG modified PEDOT:PSS layer reached 3.51, 3.64 and 3.77%, respectively, under illumination of AM 1.5 (100mW/cm²).
