Endometriosis is a common disease affecting females of reproductive age. Intestinal involvement has been estimated to occur in 15% to 37% of females with endometriosis. Unlike endometriosis of large intestine, it is very rare for the condition to manifest as small bowel obstruction caused by intestinal endometriosis. Preoperative diagnosis of intestinal endometriosis is very difficult. This disorder should be considered in the differential diagnosis of females of child-bearing age with symptoms of bowel obstruction. We report a 44-year-old woman who presented with symptoms and signs of acute small bowel obstruction. A segmental resection of the small bowel was performed with end to end anastomosis. Pathologic examination demonstrated acute small bowel obstruction secondary to intestinal endometriosis. The patient died on the second day after the surgery because her condition worsened. Intestinal endometriosis also should be included in the differential diagnosis of bowel obstruction for the prompt treatment.
Inhibition Factor on the Development of the Domestic Wood Toy Industry
황성욱,성희미,이원희 한국가구학회 2010 한국가구학회지 Vol.21 No.3
Wood material is positive with the concept of eco-friendly materials. Wood toy preference of foreign brands is also a real problem. Therefore, in this domestic situation on Toys Brand Development, there are many problems yet to be solved. At First, a wood material for toys requires the development of more sophisticated and precision materials. Second, new content, product development and training program development of the toys are needed. Characters and content development time and effort should be invested. In present, Korean brand development of wood toy with educational effects is very important issues as the use of wood to match the low carbon & green growth.
Observation of Moisture Content in Wood at Non-Steady State
황성욱,이원희 한국가구학회 2009 한국가구학회지 Vol.20 No.6
For the search of unified law of moisture movement in wood, moisture distribution of Korean red pine at non-steady state was investigated. We assume that the equilibrium moisture content (EMC) in wood depends on only temperature and relative humidity, it can be control in temperature and humidity chamber. If temperature is constant and humidity or vapor pressure is changed with sin curve shape at adequate cycles, EMC in chamber can be changed as well with sin-curve shape. The setup condition of a non-steady state in humidity control chambers is a constant temperature at 20℃and 15+10 sin ωt percent EMC. It can be found that the distribution of moisture in the specimen with varying relative humidity are illustrated various types. Moisture in wood is complicated and vibrates with the moisture sorption process. Considering a unified law of moisture movement in wood, it is considered that the most important fact is to search the method of precise diffusion & transfer coefficients.
Use of Political Blogs: Comparison of Legislator Blogs
황성욱 사이버커뮤니케이션학회 2008 사이버 커뮤니케이션 학보 Vol.25 No.3
This study compared whether the two major South Korean parties’ legislator blogs show any differences in terms of content of postings. The two parties’ legislator blogs were updated approximately once a week by posting one or more new items at the length of three pages on average. Regarding authors of postings, the two parties’ blogs showed both common and different points. The opposition party’s legislators showed more negative frames than their counterparts. The ruling party’s legislator blogs posted slightly more personal stories/interests, while the opposition party’s legislator blogs showed more policy postings. Based on the findings, practical implications were discussed.
