  • Intestinal Behçet's disease is a rare, immune-mediated chronic intestinal inflammatory disease; therefore, clinical trials to optimize the management and treatment of patients are scarce. Moreover, intestinal Behçet's disease is difficult to treat and often requires surgery because of the failure of conventional medical treatment. Administration of anti-tumor necrosis factor-${\alpha}$, a potential therapeutic strategy, is currently under active clinical investigation, and evidence of its effectiveness for both intestinal Behçet's disease and inflammatory bowel diseases has been accumulating. Here, we review updated data on current experiences and outcomes after the administration of anti-tumor necrosis factor-${\alpha}$ for the treatment of intestinal Behçet's disease. In addition to infliximab and adalimumab, which are the most commonly used agents, we describe agents such as golimumab, etanercept, and certolizumab pegol, which have recently been shown to be effective in refractory intestinal Behçet's disease. This review also discusses safety issues associated with anti-tumor necrosis factor-${\alpha}$, including vulnerability to infections and malignancy.

  • The purpose of this study was done to investigate the influence of social risk factors on each stroke type. We recruited at the Stroke Medical Center in Daejeon University Oriental Medical Hospital from July 2005 to March 2007 for this study. We divided 217 patients with acute stroke within 2 weeks as the case group(Cases), 146 people without major risk factor as the healthy control group(Normals), and 160 people as the general control group(Controls). We analyzed general characteristics such as age, sex, with or without spouse, education periods, religion, psychologic stress, and the odds ratio of each social risk factors by multivariate logistic analysis. As a result of reviewing the influence of social risk factors upon each stroke type, without spouse may be risk factor of ischemic stroke, and the undereducated may be risk factor of hemorrhagic stroke and ischemic stroke. But religion and psychologic stress had no significant relation with stroke.

  • Background: Serum-based parameters are considered non-invasive biomarkers for cancer detection. In human studies, insulin-like growth factor-I and II (IGF-I and IGF-II) and insulin-like growth factor binding protein-3 (IGFBP-3) are useful as diagnostic or prognostic markers and potential therapeutic targets. Objectives: This study examined the diagnostic utility of circulating IGF-I, IGF-II, and IGFBP-3 levels in healthy dogs and dogs with tumors. Methods: The serum concentrations of these biomarkers in 86 dogs with tumors were compared with those in 30 healthy dogs using an enzyme-linked immunosorbent assay (ELISA). Results: The ELISA results showed no difference between healthy dogs and dogs with tumors in the serum IGF-II concentrations. On the other hand, there was a significant difference in the circulating IGF-I and IGFBP-3 levels between healthy dogs and dogs with tumors. The concentrations of serum IGF-I (median [interquartile range], 103.4 [59.5-175] ng/mL) in dogs with epithelial tumors were higher than those (58.4 ng/mL [43.5-79.9]) in healthy dogs. Thus, the concentrations of serum IGFBP-3 (43.4 ng/mL [33.2-57.2]) in dogs with malignant mesenchymal tumors were lower than those (60.8 ng/mL [47.6-70.5]) in healthy dogs. Conclusions: The serum IGF-I and IGFBP-3 levels can be used as diagnostic biomarkers in dogs with tumors.

  • The majority of tubular joints commonly found in offshore jacket structures are multi-planar. Investigating the effect of loaded out-of-plane braces on the values of the stress concentration factor (SCF) in offshore tubular joints has been the objective of numerous research works. However, due to the diversity of joint types and loading conditions, a number of quite important cases still exist that have not been studied thoroughly. Among them are internally ring-stiffened two-planar TT-joints subjected to axial loading. In the present research, data extracted from the stress analysis of 243 finite element (FE) models, verified against available numerical and experimental data, was used to study the effects of geometrical parameters on the chord-side SCFs in two-planar tubular TT-joints reinforced with internal ring stiffeners subjected to two types of axial loading. Parametric FE study was followed by a set of nonlinear regression analyses to develop six new SCF parametric equations for the fatigue analysis and design of axially-loaded two-planar TT-joints reinforced with internal ring stiffeners.

  • The results of this paper show that strategic and technical factors in the integration of logistics between shipping and logistics companies act as a synchronizing factor for internal and external logistics integration. In addition, internal integration of logistics is expanded to external integration, and internal and external logistics integration is shown to enhance the logistics performance of companies. In other words, the greater the strategic need for logistics integration and the higher the utilization of logistics technology, the stronger the motivation for logistics integration. Furthermore, both internal and external integration of logistics have a positive impact on companies' logistics costs and improvement of logistics services.

  • The purpose of this study was to examine the effects of a healing garden program based on internal factors of vocational adaptation on career attitude for college students with developmental disabilities. First, healing garden program was defined by a group of experts related to education for developmental disabilities in the industry and academia through the focus group interview. Second, the healing garden program for college students with developmental disabilities was carried out for 15 weeks. Third, this study examined the effects of healing garden program based on internal factors of vocational adaptation on career attitude for college students with developmental disabilities. The participants of this study were 55 college students with developmental disabilities in N University, with 25 students placed in the experimental group and the other 30 in the control group. As a result of examination, the difference between before and after the program, it was found that factors of career attitude were improved significantly after the program in the experimental group, with Factor 1 (determination) increased from 2.08 to 3.39, Factor 2 (finality) from 2.28 to 3.19, Factor 3 (confidence) from 2.20 to 3.69, Factor 4 (preparation) from 2.12 to 3.79, and Factor 5 (independence) from 1.88 to 3.63. But the control group did not show a significant improvement after 15 weeks of the program except Factor 3 (confidence) and Factor 5 (independence). It was found that the healing garden program based on internal factors of vocational adaptation had effects on career attitude for college students with developmental disabilities. Finally, the program will contribute to vocational rehabilitation for college students with disabilities. The findings further suggest that healing gardening programs that facilitate career attitudes must be continuously developed and applied in order to establish effective transition from school to the world of vocational adaptation.

  • Prior to the 2000s, internal control had not been among the high priority issues in the management's agenda. Since then, however, it has become one of the hottest issues, and has received a significant attention as the means of improving the transparency, sustainability, and competitiveness of a company. The objectives of this paper are to examine if there has been any noticeable changes in the level of internal controls of Korean companies before and after the 2010, and to analyze the underlying drivers and issues thereto. Accounting manipulation and moral hazard were among the factors to cause the Korean financial crisis in 1997 and 2008. Since then, the capital market has had a strong pressure on Korean companies to enhance the transparency of management and accounting while the government has made the laws, requirements, and recommendations to alleviate the moral hazard problems of management and enhance the accounting transparency. Both market and government have driven companies to put more priority on the reliability of financial reporting and the compliance of applicable laws and regulations. Thereby, the market and governmental forces has led companies to enhance the level of internal controls which contribute to the reliability of financial reporting and the compliance The pressure on companies to enhance the level of internal controls may be different across industries. The capital market and government experiencing the severe financial crisis in 1997 and 2008 put even more pressure on financial companies such as banks to upgrade the reliability of financial reporting and the compliance of regulations to the global level than on non-financial companies. A survey is performed on the changes in the level of internal controls of 54 major companies consisting of 10 financial and 44 non-financial companies in Korea. The survey results show that the average level of internal controls of Korean companies has noticeably improved and that the change in the level of control environment factor is higher than that of IT control factor. The analysis on the industry differences shows that financial companies increased the level of control environment factor more than non-financial companies did while non-financial companies upgraded the level of IT control factor more than financial companies did relatively. Among internal control categories, the most improved area since the economic crisis is "Risk Assessment." The global best practices for risk management have been developed primarily in the financial industry and then spread to other industries. The general level of control practices of Korean companies has been improving significantly, but still appears below the global advanced practices.

  • 연구배경 : 호중구에 의해 매개되는 염증반응은 호중구의 수명이 매우 짧기 때문에 대부분 자연 종결된다. 패혈증에서는 이러한 호중구의 아포프토시스가 감소되어 수명이 연장되어 있어서 지속적인 염증반응이 일어나게 된다. 호중구의 수명 연장을 유도하는 많은 염증 매개 물질들이 nuclear factor-${\kappa}B$ 전사인자에 의해 조절되기 때문에 이 연구에서는 nuclear factor-${\kappa}B$가 패혈증 환자에서 관찰되는 호중 구의 아포프토시스 억제와 연관이 있을 것으로 가정하였다. 방법 : 건강한 정상인과 패혈증 환자의 호중구를 정맥혈로부터 신선하게 분리하여 실험하였다. 호중구의 아포프토시스는 특징적인 아포프토시스의 형태를 보이는 세포를 광학현미경으로 세거나 Annexin V를 이용한 유세포분석법으로 정량하였다. Nuclear factor-${\kappa}B$의 활성도는 면역형광 엽색법 또는 electrophoretic mobility shift assay로 판단하였다. 항아포프토시스 단백인 X-linked inhibitor of apoptosis의 발현 정도는 western blot으로 평가하였다. 결과 : 패혈증 환자에서 자발적 아포프토시스가 감소되어 있음을 확인하였다. 패혈증 환자의 호중구에 cycloheximide를 처치하였을 때 아포프토시스가 유의하게 증가하여 아포프토시스 감소가 새로운 단백 합성에 의존적임을 관찰하였다. 패혈증 환자의 호중구에서는 정상인과는 달리 기저상태에서도 nuclear factor-${\kappa}B$가 핵 내로 이동되어 활성화되어 있었고 nuclear factor-${\kappa}B$의 활성을 억제하였을 때 아포프토시스의 억제가 반전되었다. 또한 nuclear factor-${\kappa}B$에 의존적인 X-linked inhibitor of apoptosis 단백의 발현 수준이 정상인의 호중구에서는 24시간 동안 배양하면서 점차 감소하였지만 패혈증 환자의 호중구에서는 지속적으로 발현 수준이 유지되었다. 결론 : 패혈증 환자에서 관찰되는 호중구의 아포프토시스 억제에는 nuclear factor-${\kappa}B$ 전사인자의 활성화에 의한 생존 단백의 유도가 관여할 것으로 생각하였다.
