Thrombophlebitis of the portal venous system (PVS) with superimposed bacterial infection (septic pylephlebitis) is an extremely rare complication of Crohn`s disease (CD), and therefore diagnosis of septic pylephlebitis is difficult without high clinical suspicion. A 16-year old male patient who was diagnosed with CD 3 months earlier was admitted with recurrent fever and abdominal pain. CD activity had been well controlled with conventional medical treatment during a follow-up period. Abdominal contrast- enhanced computed tomography showed massive thrombosis in the PVS without evidence of intra-abdominal infection, and blood cultures were positive for Streptococcus viridians. There was no evidence of deep vein thrombosis or pulmonary thromboembolism, and all laboratory tests for thrombophilia were normal. Based on these findings, the patient was diagnosed with septic pylephlebitis complicated with CD, and was successfully treated with intravenous antibiotic therapy combined with anticoagulation. This case suggests that early comprehensive evaluation is crucial for immediate diagnosis and proper treatment of septic pylephlebitis in patients with CD who present with fever and abdominal pain of unknown origin, even with stable disease activity and absence of other intra-abdominal infections.

본 논문은 소양호에 서식하는 내수면어업의 주요 수산자원 중 하나인 쏘가리 (Siniperca scherzeri)의 성숙과 산란에 관하여 연구하였다. 본 논문에 사용된 쏘가리는 2014년 4월부터 11월까지 정치망과 자망을 통해 채집하였고, 암컷이 204개체로 전장범위는 113~365 mm이었고, 수컷은 197개체로 전장 범위가 140~342mm이었다. 산란기가 시작되는 5월의 수온은 15°C를 나타냈으며, 점진적으로 높아져 7월에 26°C를 나타내었다. 암컷의 생식소 숙도지수 (GSI)는 5월에서 7월까지 각각 2.3%, 4.6%, 3.1%로 나타났고, 수컷의 경우 8.0%, 6.6%, 4.5%로 나타났다. 난소 조직은 5월에 많은 수의 샘플이 중숙으로 관찰되었으며 6월에는 대다수가 성숙, 7월에는 완숙 및 방란으로 관찰되었다. 정소 조직의 경우에도 마찬가지로 5월에는 대다수가 중숙, 6월에는 성숙, 7월에는 방중으로 관찰되었다. 월별 성숙도와 생식소 숙도지수 (GSI), 생식소의 조직관찰을 통한 분석결과, 소양호에 서식하는 쏘가리의 산란기는 5월에서 6월로 추정되었다. 또한 군성숙도를 분석한 결과, 암컷 쏘가리의 50% 성숙체장은 245.16mm로 나타났다. The study about maturity and spawning of Korean Mandarin fish, Siniperca scherzeri collected using the set net and gill net in Soyangho Lake from April to November 2014 was conducted. The number of individuals was 401 (female: 204, male: 197). The total length of females ranged from 113 mm to 365 mm and that of males was from 140 mm to 342 mm. The water temperature in May which is the start of spawning season indicated about 15°C and gradually increased to July (26°C). Gonadosomatic index (GSI) of females indicated 2.3%, 4.6% and 3.1%, respectively, in May to July. Males’ value showed the similar pattern recording 8.0%, 6.6% and 4.5% in the same time. According to histological observations of gonadal tissue, the most of female in May had the gonadal tissue of maturing and mature stage. And the ovary of June was mostly in the stage of ripe and spawning and a number of individuals in July was recovery stage. In the case of male, a number of males in May showed in the stage of mature. The testis of June showed that mature sperm was releasing. And the testis of July was mostly in recovery stage. The total length at 50% group maturity was estimated 245.16 mm. As shown in the above, the main spawning period of S. scherzeri was May to June.

Objectives: This study was performed to review studies on Essential Tremor (ET) in Traditional Chinese medicine (TCM). Methods: We reviewed papers in the China National Knowledge Infrastructure (CNKI) from 2007∼ 2016. Search keywords were 原發性震?, 特發性震?, essential tremor and idiopathic tremor, and excluded non-clinical studies, non-related to ET or TCM studies, theses for degrees and non-Randomized Controlled Trial (RCT). The quality of the articles was assessed by Jadad scale and the Risk of Bias (RoB). Results: Thirteen studies were selected. `Criteria for the diagnosis of ET` was most frequently used as diagnostic criteria. `Tremor rating scale` was primarily used for outcome measurement. Meta-analysis of nine trials revealed the effective rate of acupuncture and Western medicine (WM+Acu) groups was significantly higher compared to the WM group (RR: 1.48, 95 percent CI: 1.20 to 1.82, p=0.0002, I<sup>2</sup>=0 percent) and tremor rating scale was also significantly decreased in the treatment group (MD: -1.35, 95 percent CI: -2.17 to -0.54, p=0.001, I<sup>2</sup>=0 percent). Also, effective rates of Electro-acupuncture (EA) and Chinese herbal medicine (CHM) groups were significantly higher than that of the WM group {(RR: 1.53, 95 percent CI: 1.22 to 1.92, p=0.0003, I2=0 percent) in EA vs. WM and (RR: 1.35, 95 percent CI: 1.16 to 1.57, p<0.0001, I<sup>2</sup>=0 percent) in CHM vs. WM}. However, the quality of selected clinical studies was poor. Conclusions: Treatment of ET in TCM may be more effective and safe than in Western medicine. Therefore, we hope this study will lead to further clinical research on treatment of ET in Korean medicine. Key Words: Essential Tremor, Idiopathic Tremor, Traditional Chinese Medicine.

The effects of surface modification by nitric acid on the pre-treatment of electroless copper plating were investigated. Copper was electroless-plated on the nitric acid treated graphite activated by a two-step pre-treatment process (sensitization + activation). The chemical state and relative quantities of the various surface species were determined by X-ray photoelectron spectroscopy (XPS) after nitric acid modification or pre-treatment. The acid treatment increased the surface roughness of the graphite due to deep and fine pores and introduced the oxygen-containing functional groups (-COOH and O-C=O) on the surface of graphite. In the pre-treatment step, the high roughness and many functional groups on the nitric acid treated graphite promoted the adsorption of Sn and Pd ions, leading to the uniform adsorption of catalyst (Pd<SUP>0</SUP>) for Cu deposition. In the early stage of electroless plating, a lot of tiny copper particles were formed on the whole surface of acid treated graphite and then homogeneous copper film with low variation in thickness was formed after 30 min.

경기도 가평군의 가평천 일대에서 2016년 9월과 2017년 2, 4월에 쉬리 245개체를 채집하여 이석과 전장빈도분포법을 이용한 연령추정과 23가지의 계측형질을 이용하여 연령에 따른 성적이형을 조사하였다. 연령추정 결과 만 2년생부터 만 4년생의 비율이 높았고 만 5년생이 최대연령이었다. 23개의 계측형질 중 9개의 형질에서 성별 간에 유의한 차이가 있었다. 이중 뒷지느러미에서 나타나는 성적이형은 수컷의 뒷지느러미 연조가 길게 신장되어 뒷지느러미 폭과 길이가 암컷에 비해 넓고 긴 특징을 보이는 주요한 성적이형으로 나타났다. 또한 산란기에 수컷개체는 뒷지느러미의 연조에 추성이 발달하는 성적이형을 나타내었으나 뒷지느러미를 제외한 다른 계측형질과 외부형질에서 성별에 따른 성적이형이 나타나지 않았다. 성적으로 성숙하는 만 2년생 개체부터 성적이형이 나타났으며, 당년생 치어와 만 1년생 개체에서는 성적이형이 나타나지 않았다. 산란기는 4월에서 5월이었으며, 만 2세부터 산란에 참여하였다. 주요 산란 연령은 만 3세부터였으며, 최대 생식소 도지수(GSI)는 만 5세에서 암컷 14.91, 수컷 8.96으로 나타났다. Age estimation and sexual dimorphism of Coreoleuciscus splendidus were estimated using otolith, length-frequency distribution and 23 morphological measurements, from 245 individuals collected from September 2016, February and April 2017 in the Gapyeong stream, Han River, Korea. Result of age estimation of C. splendidus, we most examined were 2, 3 and 4-age, and the maximum observed ages were 5-age. Nine out of twenty-three morphometric measurements were significantly different between the genders. Anal fin have showing major sexual dimorphism in particular between adult individuals. This sexual dimorphism was based on extension of anal fin soft rays of male individuals. Therefore anal fin of males is always longer and wider than females. During spawning season male individuals possess nuptial tubercles on anal fin rays. However, another measurements and morphological characters does not exhibit sexual dimorphism in the between male and female individuals. The sexual dimorphism was observed to only over 2-years old individuals with sexual maturity. But juvenile and 1-years old individuals do not have sexual dimorphism with sexual maturity. Peak season of spawning was April to May and they start first spawning at 2-age. The ages at major spawning groups were most 3-age, and they maximum GSI index was 14.91 (female), 8.96 (male) at 5-age, respectively.

The effects of heat treatment time and cooling method on microstructure and mechanical property of Cu-22wt%Sn alloy were discussed. α+δ mixed phase structure was obtained in air-cooled specimens after heat treatment at 775, 750, and 700℃ for 1 hour. On the other hand, in water-cooled specimens, α+β' martensite mixed phase was obtained. In the case of water-cooled specimens, the hardness value decreased with decreasing heat treatment temperature because the volume fraction of α phase with low hardness value increased as the heat treatment temperature decreased. In water-cooled specimen after heat treatment at 600oC, γ' martensite was formed instead of β' martensite. The hardness value of γ' martensite was lower than those of β' and δ phases.

Cryptococcus neoformans is an organism that mainly causes opportunistic infection in immunocompromised patients. It can also cause various infections in immunocompetent patients including pulmonary cryptococcosis, but it is rare. Steroids are used in clinical practice for treatment of a wide array of disease, because of their anti-inflammatory or immunosuppressive action. But, steroids use predisposes patients to a variety of infection by interfering with host defense mechanism. Infections associated with steroids are dependent on the route of administration, dose, and duration of therapy. Generally, the rate of infection is not increased in patients receiving low dose and limiting periods administration. We presented a case of pulmonary cryptococcosis obscured by cryptogenic organizing pneumonia (COP) in 68-year old female with an immunocompetent patient after low dose and short duration of steroid therapy and review all published casese.

Three specimens of larvae (5.2∼7.8 mm in standard length (SL)), of the family Scombridae, were collected from the southeastern waters off Jeju Island in August, 2014. These specimens were identified to Katsuwonus pelamis have melanophores distributed on the 1st dorsal-fin spines and post ventral margin on caudal peduncle. An analysis of the cytochrome oxidase submit I (COI) sequences (652 base pairs) of mitochondrial DNA showed that our specimens must be K. pelamis, because their sequences were concordant with those of the adult K. pelamis (genetic distance= 0.000∼0.002), followed by Auxis rochei (genetic distance= 0.061∼0.063) and Euthynnus affinis (genetic distance= 0.077∼0.079). During the larval stage, K. pelamis differed from Thunnus spp. species in melanophores distribution period of 1st dorsal-fin spines, lower jaws and ventral margin on caudal peduncle. In conclusion, occurrence of K. pelamis larvae means Korean waters are potential spawning ground of K. pelamis.

Objectives: The purpose of this study was to investigate clinical trends of Traditional Chinese Medicine (TCM) on combined treatment of acupuncture and relaxation therapy. Methods: Clinical trials based on acupuncture and relaxation therapy searched and were selected from China National Knowledge Infrastructure (CNKI). In this study we selected clinical research articles using acupuncture and relaxation therapy as intervention. Studies were assessed by Risk of Bias (RoB) tool, and Jadad scale. Results: Eleven randomized controlled trials on combined treatment of acupuncture and relaxation therapy were selected, and these studies were published in China. Most studies have targeted psychiatric disorders such as insomnia and anxiety. Manual Acupuncture (MA) was the most used acupuncture treatment, and in five studies two or more relaxation therapies were used in parallel. Although the treatment result using acupuncture and relaxation therapy was superior, heterogeneity of the control group was high and it was difficult to estimate additional effects of relaxation therapy. Conclusions: Qualitative analysis revealed that the combination of acupuncture and relaxation was more effective than control in most studies. However, quality of most studies was low. Therefore, higher quality clinical research on combined treatment of acupuncture and relaxation therapy is required.
