Objectives : Chim-Gu-Kyung-Heom-Bang(CGKHB; 鍼灸經驗方) is the needle and moxa specialized document written by the doctor specialized in needle and moxa treatment of Joseon(朝鮮), Heo Im(1570-1647). The document was published in April 1644(22nd year of King Injo). CGKHB contains the needle and moxa treatment techniques accumulated by the Joseon Dynasty as well as the personal experience of Heo Im. The aim of this study is to restore the past treatment method as a method of Needle Insertion Method at CV12(NIM-CV12, needle to penetrate blood vessel technique) in CGKHB.. Methods : Through Dong-Yi-Bao-Gam(DYBG; 東醫寶鑑), the implication of Korean medicine study of the Jungwan(CV12) has been studied. Next is the contemplation of the NIM-CV12 of CGKHB with the Acupuncture Treatment Using Jungwan(中脘鍼法) of Park Tae-won and Acupuncture Treatment for Byeokjeok(癖積鍼法) of "Geup Yubang". Results and Conclusions : 1. CV12 is one of the acupuncture points representing stomach(脾胃), middle energizer(中焦), phlegm-fluid retention(痰飮) and greater yin(太陰). 2. NIM-CV12 of CGKHB is the technique to penetrate the needle into the CV12 strictly relying on tactile sense of a person who give the penetration. This CV12 administration was carried out at intervals of every 7 or 8 day. During the administration period, the patient was not allowed to intake excessive amount of food. 3. The Acupuncture Treatment Using Jungwan(中脘鍼法) of Park Tae-won and Acupuncture Treatment for Byeokjeok(癖積鍼法) of "GeupYubang", existed in the same era of the NIM-CV12 of CGKHB, have similar linkage to the NIM-CV12 of Heo Im.

Resveratrol, or its glycoside form piceid, is a dietary antioxidant polyphenolic compound, found in grapes and red wine that has been shown to have protective effects against cardiovascular disease. However, very low water solubility of the compound may limit its application in the food and pharmaceutical industries. The amylosucrase (AMAS) of Alteromonas macleodii Deep ecotype was expressed in Escherichia coli and showed high glycosyltransferase activity to produce the glucosyl piceid when piceid was used as an acceptor. The conversion yield of piceid glucoside was 35.2%. Biotransformation using culture of the E. coli harboring the amas gene increased the yield up to 70.8%. The transfer product was purified by reverse phase chromatography and recycling preparative HPLC, and the molecular structure of the piceid glucoside was determined using NMR spectroscopy. The piceid glucoside was identified as glucosyl-${\alpha}$-($1{\rightarrow}4$)-piceid. The solubility of glucosyl piceid was 5.26 and 1.14 times higher than those of resveratrol and piceid, respectively. It is anticipated that dietary intake of this compound is more effective by enhancing the bioavailability of resveratrol in the human body because of its hydrophilic properties in the intestinal fluid.

국지성 집중호우에 따른 도심지 내수 침수 피해의 주원인으로 하수관거의 설계기준을 초과하는 강우가 침수피해의 주요 원인이며, 도심화로 인해 불투수 면적이 증가함에 따라 유출되는 시간이 짧아 저지대의 피해는 불가피하다. 2010년과 2011년에 100년 이상의 강우사상이 서울시에 연이어 나타나면서 집중호우로 인한 피해지역이 유사하게 나타났으며, 광화문 거리의 연이은 침수는 현재 서울시의 하수관거의 용량과 빗물펌프장 및 저류조 시설로 구성된 기존 수방대책의 한계점을 보이고 있다. 이에 서울시는 광화문 일대의 배수능력을 향상시키기 위하여 효자배수분구 빗물배수터널을 계획하고 있다. 일본, 미국 및 유럽 등지에서는 대심도 지하수로 시설에 대한 수리실험 및 수치 연구를 바탕으로 다양한 지하방수로가 건설되어 국지성 집중 강우에 대해 적절히 대응하고 있으나, 국내의 경우에는 대심도 지하방수로 시설에 대한 연구가 미비하여 지하방수로 설계 지침 및 기술적 자료가 부족한 실정이다. 그러므로 대심도 빗물배수터널 시설에서의 흐름특성 분석에 관한 수리실험 및 수치해석 등의 구체적인 연구가 필요하다고 판단된다. 본 연구에서는 수리모형 실험의 물질적 및 시간적 한계를 극복하기 위하여 일반적으로 3차원 유체거동의 특성분석에 많이 사용되는 Fluent 6.3 모형을 이용하여 대심도 빗물배수터널 시설의 접선식 유입구에 대한 흐름특성을 수치모의 하였다. 접선식 유입구 및 수직갱(drop shaft)에 대한 기하 모형의 격자망은 수치해석의 안정성 확보를 위하여 그림 1과 같이 6면체 격자로 구성하였다. 맨홀 내의 다상유동을 고려하기 위하여 VOF(Volume of Fluid) Scheme을 적용하였으며, 수치해석 방법으로는 비정상류, 1st order implicit method를 사용하였다. Fluent에서의 난류 흐름을 계산하는 방법에는 난류 운동에너지와 난류 에너지 소산율 $\epsilon$의 전달 방정식을 도입한 k-$\epsilon$ 난류 모형을 채택하였다.

Urinary obstructions from ureteral calculi are one of the causes of postrenal acute kidney injury (AKI). Here we present a case of AKI caused by a 4 mm ureteral calculus with postobstructive diuresis following the spontaneous passage of the calculus. A 13-year-old girl who underwent nephrectomy for the removal of a neuroblastoma eight years previously, visited our institution because anuria had developed over the preceding five days. The serum creatinine level was elevated at 13.4 mg/dL. Radiological examinations showed the right solitary kidney with moderate hydronephrosis and a 4 mm calculus in the upper right ureter. The patient immediately underwent hemodialysis. After the ureteral calculus was passed spontaneously on day 2 of hospitalization, urinary output increased to more than 5,200 mL per day. Intravenous fluid replacement with careful monitoring of weight, intake, output, and serum and urine electrolytes was performed. On day 5 of hospitalization, the patient's condition stabilized.

To investigate additive effects of endocrine disruptors, we have histopathologically studied the exchanges of the reproductive organ to ovariectomized ICR mice. Female ICR mice were ovariectomized and then treated with endocrine disruptors after two weeks. Macroscopic exchanges, which were body weight, feed and water intake, of all groups were not seen during experiment period. Histopathological changes of uterine epithelial cells, vaginal epithelial cells, mammary glands and the diameter in uterine tubles were observed. In the results, the histopathological sensitivity to endocrine disruptors effect was more seen to the vaginal epithelial cell height than others. The additive estrogenic effects of endocrine disruptors, which were combinations of DEHP, DBP and BPA, were seen with E2 and BPA treatments. These results offers a sysmatic and mechanistically informative approach to assessing estrogenicity. It provides a useful profile of activity using a reasonable amount of resources and is compatible with the study of individual chemicals as well as the investigation of interactions among combinations of chemicals.

In this study, we aimed to assess the effect of flaking on the nutrient digestibility of corn grain in ruminants. In this regard, in vitro rumen fermentation, in situ rumen degradability, and in vivo metabolic experiments were performed. The automated gas production technique was used for the in vitro fermentation experiments. Six types of corn flakes with various degrees of gelatinization (32%, 41%, 48%, 66%, 86%, and 89%) were ground and incubated in rumen fluid to measure rumen fermentation characteristics and digestion rate. The in situ degradability of ground corn, whole corn, and corn flakes with 62% and 66% gelatinization was measured by incubation in the rumen of two cannulated Holstein cows. In vivo metabolic experiments were performed using 12 crossbred goats (29.8 ± 4.37 kg) using a 3 × 3 Latin square design. The dietary treatments consisted of ground corn and flaked corn with 48% or 62% gelatinization. In vitro experiments showed that as the degree of gelatinization increased, the digestion rate increased linearly, while the discrete lag time decreased linearly (p < 0.05). The effective rumen dry matter degradability, determined by in situ fermentation, was 37%p lower in corn flakes than ground corn, assuming a passage rate of 6%/h (p < 0.01), and there was no difference between the two flakes. In the in vivo experiment, there was no difference in dry matter intake, average daily gain, feed efficiency, and nitrogen utilization among the treatment groups (p > 0.05); however, the crude fat digestibility was lower for corn flakes than for ground corn (p < 0.05). To summarize, the rate of fermentation of corn flakes increased as the degree of gelatinization increased. However, non-ground corn flakes had lower rumen digestibility and did not improve in vivo apparent nutrient digestibility, compared with ground corn. In contrast to the assumption that flaked corn provides more energy to ruminant animals than ground corn, we conclude that the digestibility and energy value of corn flakes are lower than those of ground corn if mastication does not sufficiently reduce the particle size of corn flakes.

Ascites is the accumulation of fluid in the peritoneal cavity, and it is generally allied with liver disease like cirrhosis of the liver. The ascites is commonly associated with liver cirrhosis, malignancy, or cardiovascular disease today. The liver cirrhosis is the most significant cause of ascites in developed countries as per the available data. In the modern medicine system, the treatment includes the restriction of sodium intake, use of diuretics, and paracentesis done in severe cases. There are many side effects of synthetic chemical diuretics, and their long-term use is not recommended. The alternative medicine like Unani system of medicine provides natural diuretics and drugs which also have protective effects on kidney, liver and other internal organs. It is well known in all drug systems that the prognosis is poor in ascites, but the use of Unani herbal medicines can minimize the side effects caused by synthetic chemical diuretics. The natural herbs used for the management of ascites have fewer side effects as compared to synthetic drugs. The natural drugs can be used for longer duration and provide some dietary supplement which improves the quality of life. This review addressed the thorough treatment of ascites by natural diet and medications.

Purpose: The purpose of this study was to evaluate the efficacy of applying a defecation encouragement program for patients undergoing total knee replacement arthroplasty (TKRA). Methods: This program was based on the nursing best practice guideline: prevention of constipation in the older adult population by the National Guideline Clearing House (NGC) in 2011, which included fluid intake, bowel training, and abdominal and pelvic floor exercises. A team of one orthopaedic clinical nurse specialist and six orthopaedic nurses with a 10 years of clinical experience applied and assisted patients with the program. Formal counsel was provided by one orthopaedic doctor, one gastroenterologist, and one exercise therapist. Patients who defecated one day prior to or on the day of TKRA surgery were included. Data collected from 72 subjects were analyzed using SPSS/WIN 21.0. Results: Time until first defecation after surgery was 2.4±1.1 days in experimental group, which was significantly shorter than the 3.5±0.9 days in control group (t=4.28, p<.001). Constipation assessment scale showed significantly lower points (t=2.55, p=.013) in experimental group (1.3±1.2) compared to control group (2.6±2.6). The experimental group and control group were 17.3±7.67 and 23.7±14.43, respectively, and the experimental group used less laxatives (t=2.83, p=.021). Conclusion: A defecation encouragement program was proved to be an appropriate nursing intervention for patients undergoing TKRA. This study confirmed that constipation is a nursing problem that can be sufficiently prevented if nurses are interested and encourage defecation.

Investigation on operation of the test apparatus for the M4 semi-freejet tests with a full-scale vehicle model was carried out utilizing domestic facilities. An integrated design of the experimental apparatus and the vehicle model was obtained through iterative computational fluid dynamics (CFD) analysis. The test results showed that the M4 nozzle of the apparatus was fully expanded to provide required test conditions. It was also found that the intake of the vehicle model successfully started, and the corresponding shadowgraph images were recorded during the test. A variable nozzle of the model was set to adjust the back pressure of the model combustor, and wall-static pressures were measured to obtain the pressure distribution at the main locations of the model. The flame of torch ignitors and pilot fuel ignition were observed in a flame-holder of the combustor.

Objective: This study aimed to assess the impact of a hydroethanolic extract of walnut green husks (WGH) on rumen fermentation and the diversity of bacteria, methanogenic archaea, and fungi in sheep fed a high-concentrate diet. Methods: Five healthy small-tailed Han ewes with permanent rumen fistula were selected and housed in individual pens. This study adopted a self-controlled and crossover design with a control period and an experimental period. During the control period, the animals were fed a basal diet (with a ratio of concentrate to roughage of 65:35), while during the treatment period, the animals were fed the basal diet supplemented with 0.5% hydroethanolic extract of WGH. Fermentation parameters, digestive enzyme activities, and microbial diversity in rumen fluid were analyzed. Results: Supplementation of hydroethanolic extract of WGH had no significant effect on feed intake, concentrations of total volatile fatty acids, isovalerate, ammonia nitrogen, and microbial protein (p>0.05). However, the ruminal pH, concentrations of acetate, butyrate and isobutyrate, the ratio of acetate to propionate, protozoa count, and the activities of filter paper cellulase and cellobiase were significantly increased (p<0.05), while concentrations of propionate and valerate were significantly decreased (p<0.05). Moreover, 16S rRNA gene sequencing revealed that the relative abundance of rumen bacteria Christensenellaceae R7 group, Saccharofermentans, and Ruminococcaceae NK4A214 group were significantly increased, while Ruminococcus gauvreauii group, Prevotella 7 were significantly decreased (p<0.05). The relative abundance of the fungus Pseudomonas significantly increased, while Basidiomycota, Fusarium, and Alternaria significantly decreased (p<0.05). However, there was no significant change in the community structure of methanogenic archaea. Conclusion: Supplementation of hydroethanolic extract of WGH to a high-concentrate diet improved the ruminal fermentation, altered the structure of ruminal bacterial and fungal communities, and exhibited beneficial effects in alleviating subacute rumen acidosis of sheep.
