Locally recurrent penile apocrine carcinoma initially diagnosed as metastatic adenocarcinoma of colon

Chinese Journal of Cancer Research 2013年第6期25卷 777-780页

Apocrine carcinoma is a rare malignant adnexal neoplasm. The differential diagnosis between apocrine carcinoma and cutaneous metastasis is often difficult. Here, we report a case of locally recurrent penile apocrine carcinoma initially diagnosed as metastatic adenocarcinoma of the colon. A 75-year-old man with a history of surgical resection due to sigmoid colon cancer and penile metastasis two years prior to this study presented with a nodule at the left penile base. He underwent a wide local resection of the penile mass under a suggested preoperative diagnosis of extra-mammary Paget＇s disease （EMPD） associated with previous sigmoid colon cancer. However, the previously and currently resected penile masses were identified as primary apocrine carcinoma upon hematoxylin and eosin （H＆E） staining and immunohistochemical staining. Although the incidence is extremely rare, both clinicians and pathologists should be alert to the possibility of synchronous double primary apocrine carcinoma in cancer patients with malignant cutaneous lesions.

Duodenal obstruction following acute pancreatitis caused by a large duodenal diverticular bezoar

引用

World Journal of Gastroenterology 2012年第38期18卷 5485-5488页

作者： Ji Hun Kim Jae Hyuck Chang Sung Min nam Mi Jeong Lee Il Ho Maeng Jin Young Park yun Sun Im Tae Ho Kim Il Young Park Sok Won Han Department of Internal Medicine College of Medicine The Catholic University of Korea Seoul 137-701 South Korea Department of Surgery College of Medicine The Catholic University of Korea Seoul 137-701 South Korea

Bezoars are concretions of indigestible materials in the gastrointestinal tract. It generally develops in patients with previous gastric surgery or patients with delayed gastric emptying. Cases of periampullary duodenal divericular bezoar are rare. Clinical manifestations by a bezoar vary from no symptom to acute abdominal syndrome depending on the location of the bezoar. Biliary obstruction or acute pancreatitis caused by a bezoar has been rarely reported. Small bowel obstruction by a bezoar is also rare, but it is a complication that requires surgery. This is a case of acute pancreatitis and subsequent duodenal obstruction caused by a large duodenal bezoar migrating from a periampullary diverticulum to the duodenal lumen, which mimicked pancreatic abscess or microperforation on abdominal computerized tomography. The patient underwent surgical removal of the bezoar and recovered completely.

Domain-engineered BiFeO3 thin-film photoanodes for highly enhanced ferroelectric solar water splitting

引用

Nano Research 2018年第2期11卷 642-655页

作者： Song, Jaesun Kim, Taemin Ludvic Lee, Jongmin Cho, Sam Yeon Cha, Jaeseong Jeong, Sang yun An, Hyunji Kim, Wan sik Jung, Yen-Sook Park, Jiyoon Jung, Gun Young Kim, Dong-Yu Jo, Ji Young Bu, Sang Don Jang, Ho Won Lee, Sanghan School of Materials Science and Engineering Gwangju Institute of Science and Technology (GIST) Gwangju Republic of Korea Department of Materials Science and Engineering Research Institute of Advanced Materials Seoul National University Seoul Republic of Korea Department of Physics Chonbuk National University Jeonju Republic of Korea

In photoelectrochemical （PEC） water splitting, charge separation and collection by the electric field in the photoactive material are the most important factors for improved conversion efficiency. Hence, ferroelectric oxides, in which electrons are the majority carriers, are considered promising photoanode materials because their high built-in potential, provided by their spontaneous polarization, can signifi＇canfly enhance the separation and drift of photogenerated carriers. In this regard, the PEC properties of BiFeO3 thin-film photoanodes with different crystallographic orientations and consequent ferroelectric domain structures are investigated. As the crystallographic orientation changes from （001）pc via （ll0）pc to （lll）p~, the ferroelastic domains in epitaxial BiFeO3 thin films become mono-variant and the spontaneous polarization levels increase to 110 btC/cm2. Consequent136 the photocurrent density at 0 V vs. Ag/AgC1 increases approximately 5.3-fold and the onset potential decreases by 0.180 V in the downward polarization state. It is further demonstrated that ferroelectric switching in the （lll）pc BiFeO3 thin-film photoanode leads to an approximate change of 8,000% in the photocurrent density and a 0.330 V shift in the onset potential. This study strongly suggests that domain-engineered ferroelectric materials can be used as effective charge separation and collection layers for efficient solar water-splitting photoanodes.

Energy Harvesting Strategy Using Piezoelectric Element Driven by Vibration Method

引用

Wireless Sensor Network 2010年第2期2卷 100-107页

作者： Dong-Gun Kim So-nam yun Young-Bog Ham Jung-Ho Park 不详

This study demonstrates a method for harvesting the electrical power by the piezoelectric actuator from vibration energy. This paper presents the energy harvesting technique using the piezoelectric element of a bimorph type driven by a geared motor and a vibrator. The geared motor is a type of PWM controlled device that is a combination of an oval shape cam with five gears and a speed controller. When using the geared motor, the piezoelectric element is size of 36L×13W×0.6H. The output voltage characteristics of the piezoelectric element were investigated in terms of the displacement and vibration. When using the vibrator, the electric power harvesting is based on piezoelectric effect and piezoelectric vibrator consists of a magnetic type oscillator, a cantilever, a bimorph actuator and controllers. Low frequency operating technique using piezoelectric vibrator is very important because normal vibration sources in the environment such as building, human body, windmill and ship have low frequency characteristics. We can know from this study results that there are many energy sources such as vibration, wind power and wave power. Also, these can be used to the energy harvesting system using smart device like piezoelectric element.

Numerical Study on the Effects of Contraction Ratio in a Two-Phase Flow Injection Nozzle

引用

Open Journal of Fluid Dynamics 2016年第1期6卷 1-10页

作者： Haider Ali Kyung Won Kim Jae sik Kim Jong yun Choi Cheol Woo Park School of Mechanical Engineering Kyungpook National University Daegu Korea Podomaul Co. Ltd. 1190 Kumchang-Ro Daechang-Myon Yeongcheon-Si Korea B.C.M. Co. Ltd. 81 Yeomsaekgongdancheon-Ro Seo-Gu Daegu Korea

The Euler-Euler numerical method was used to investigate the effects of contraction ratio on twophase flow mixing with mass transfer in the flow injection nozzle. The geometric shape of the nozzle was modified to improve carbonation efficiency. A gas inlet hole was created to increase the flow mixing of CO2 with water. A nozzle throat was also introduced to increase the gas dissolution by increasing flow rates. Various contraction ratios of nozzle throat, inlet gas and liquid velocities, and gas bubble sizes were employed to determine their effects on gas hold-up, gas concentration, and mass transfer coefficient. Results revealed that the flow injection nozzle with high contraction ratios improved carbonation because of high gas hold-up. Gas concentration was directly related to contraction ratio and gas flow velocities. Carbonation reduced when high liquid velocities and large gas bubbles were employed because of inefficient flow mixing. This study indicated that flow injection nozzle with large contraction ratios were suitable for carbonation because of their ability to increase gas hold-up, gas concentration, and mass transfer coefficient.
