Purpose : Henoch-$Sch{\ddot{o}}nlein$ purpura(HSP) is a systemic vasculitis, characterized by cutaneous palpable purpura, gastrointestinal(GI) symptoms, arthritis and renal involvement. In general, the prognosis is determined by GI complication as well as the severity of nephritis. In this study, we analyzed the statistical relationship between the GI symptom and other clinical findings for assessing the prognosis, and evaluated abdominal ultrasonographic findings for early diagnosis of this disease with atypical clinical presentation and early detection of serious GI complications. Methods : One hundred seventy seven patients with HSP in the Department of Pediatrics, Wonkwang University Hospital from January 1994 to June 2004, were enrolled. We retrospectively analyzed charts about clinical and abdominal ultrasonographic findings, and classified our patients into two groups(GI-Sx(-), GI-Sx(+)) for statistical analysis. Results : The ratio of female to male is 1.5 : 1. The peak age incidence was five to eight years in 95 cases(53%). The GI symptoms appeared in 117 cases(66%), which include abdominal pain 115 (98 %), tenderness 45(38%), nausea and vomiting 35(30%), bloody stool 10(8.5%), diarrhea four(3.4%), rebound tenderness four(3.4%), and also intussusception and appendicitis were complicated in five and two cases respectively. GI-Sx(+) group had an increased risk of renal involvement and relapse than the GI-Sx(-) group. But there were no relationships about sex and age incidence, or other clinical and laboratory findings between two groups. Ultrasonographic findings in 98 patients with GI symptoms included small bowel thickening in 70 cases(71%) in which duodenum, jejunum and ileum were involved in 71%, 45.7%, 40% respectively, small bowel dilatation in 41 cases(42%), lymph node swelling in 46 cases(47%), and ascites in 25 cases(25.5%). Conclusion : GI symptoms in patients with HSP suggested increased risk of renal involvement and relapse. Abdominal ultrasonography could be helpful in the early diagnosis on atypical clinical presentation and early detection of serious GI complication in these patients.

The high-level Space Situational Awareness (SSA) objective is to provide to the users dependable, accurate and timely information in order to support risk management on orbit and during re-entry and support safe and secure operation of space assets and related services. Therefore the risk assessment for the re-entry of space objects should be managed nationally. In this research, the Software for Re-Entry Prediction of space objects (SREP) was developed for national SSA system. In particular, the rate of change of the drag coefficient is estimated through a newly proposed Drag Scale Factor Estimation (DSFE), and is used for high-precision orbit propagator (HPOP) up to an altitude of 100 km to predict the re-entry time and position of the space object. The effectiveness of this re-entry prediction is shown through the re-entry time window and ground track of space objects falling in real events, Grace-1, Grace-2, Tiangong-1, and Chang Zheng-5B Rocket body. As a result, through analysis 12 hours before the final re-entry time, it is shown that the re-entry time window and crash time can be accurately predicted with an error of less than 20 minutes.

We studied absorbance of tinted dye absorbed into tinted lenses by Spectrophotometric method. Used lenses and tinted dye were CR-39 plastic optical lenses and Ons & $Lavas^{(R)}$ Blue, respectively. Absorbance values of tinted dye absorbed into tinted lenses were obtained from the differences of absorbance values between tinted lenses and CR-30 lenses. Average concentrations of tinted dye absorbed into tinted lenses were obtained from the mass differences between tinted lenses and CR-30 lenses. The relationship between absorbance and average concentration for tinted dye absorbed into tinted lenses was also confirmed to follow Beer’s law. The absorption coefficient calculated from the tangent of the calibration curve was determined to be a=0.983 $Lg^{-1}cm^{-1}$.

크로스사이트 스크립팅은 웹 애플리케이션의 취약점으로 사용자의 정보(쿠키, 세션 등)를 탈취하거나, 비정상적인 기능을 자동으로 수행하게 하거나 할 수 있다. 크로스사이트 스크립팅(XSS) 공격유형은 한 번의 HTTP 요청과 응답에서 행해지는 XSS인 반사 XSS(reflect XSS)와 페이로드를 전송한 뒤 다수의 피해자가 해당 페이지에 접속하면 XSS 공격에 노출되는 저장 XSS(Stored XSS)로 나눌 수 있다. 그리고 크로스사이트 스크립팅 공격에 대한 방어로 사용자 입력하는 데이터에 대한 입력 값 검증, HTML 인코딩 과정에서의 출력 값에 대한 검증, 사용자가 악의적 코드를 웹 어플리케이션에 삽입하기 위한 시도를 막기 위해 위험 가능성 삽입지점 제거를 제시하였다. 본 논문에서는 이 두 가지 방법에 대한 공격방법과 절차를 제시하고 모의해킹을 수행하였다. 이를 통해 크로스사이트 스크립팅 공격에 대한 이해가 가능하고 대응책을 통해 공격에 대비할 수 있도록 하였다. Cross Site Scripting enables hackers to steal other user's information (such as cookie, session etc.) or to do abnormal functions automatically using vulnerability of web application. This attack patterns of Cross Site Scripting(XSS) can be divided into two types. One is Reflect XSS which can be executed in one request for HTTP and its reply, and the other is Stored XSS which attacks those many victim users whoever access to the page which accepted the payload transmitted. To correspond to these XSS attacks, some measures have been suggested. They are data validation for user input, output validation during HTML encoding procedures, and removal of possible risk injection point to prevent from trying to insert malicious code into web application. In this paper, the methods and procedures for these two types are explained and a penetration testing is done. With these suggestions, the attack by XSS could be understood and prepared by its countermeasures.

To realize the U-healthcare system, the mobile patient monitoring system is of the essence. In this monitoring system, a patient's real-time data on biometrics and location must be transferred to predeterminate destination server ceaselessly. As the number of mobile patients increases steadily or mobile patients are moving into some specific area, the load balancing solution to real-time data congestion problem is needed. In this paper, we propose a new mobile patient monitoring system with Torus topology where three layers are connected hierarchically and the intermediate layer takes charge of priority-based load balancing. For the formalized design and verification of proposed system, we describe the overall structure with connectivity among its components and implement major components in pseudo-code by adopting a system specification-based approach. This approach makes the design and verification of our mobile patient monitoring system more flexible and accurate.

Acute necrotizing esophagitis, which presents as a black esophagus on endoscopy, is a rare disorder. We report a case of a 48-year-old male with acute necrotizing esophagitis, associated with alcoholic hepatitis. He was admitted to our hospital because of hematemesis. On initial upper esophagogastroduodenoscopy, diffuse friable black colored mucosa at whole length of the esophagus was observed. After conservative treatment with proton-pump inhibitor, esophageal mucosal lesion was healed without complication. (Korean J Gastroenterol 2010;56:373-376)

Why Are Products of Social Enterprises Not Purchased Continuously? : A Re-Purchase Model for Social Enterprises

최은정(Eun Jung Choi) People&Global Business Association 2021 Global Business and Finance Review Vol.26 No.3

Purpose: In the last decades, practitioners, including governments, have been interested in social enterprises (SEs) as a new sector, called the “fourth sector,” because of their social goals through commercial activities. Although many countries are supporting SEs because of their high evaluation of social contributions, in reality, they are highly dependent on government support, and many SEs are facing difficulties in sustainable management. Due to this issue, some studies have been conducted for the sustainable management of SEs, but research on SEs does not seem sufficient yet. For its sustainable management, the mechanisms between the important factors affecting the sustainable purchase intention of SEs must be understood from a marketing viewpoint. Thus, this study aims (1) to investigate the impact of SEs on their products; and (2) to provide a re-purchase model for SEs. Design/methodology/approach: This study consists of two empirical studies collecting data from consumers who have purchased SE’s products in South Korea. Study 1 is an exploratory study to elicit sub-constructs for SEs and their products. Study 2 tests the hypotheses using structural equation model analysis. Findings: The result of Study 1 revealed four sub-constructs for SE’s corporate associations (environment friendly, local community oriented, social responsibility, and employee welfare) and four sub-constructs of the product associations (functional, symbolic, emotional, and social). Meanwhile, the results of Study 2 show that some hypothetical paths in the conceptual re-purchase model for SEs are significant. Environment friendly only affects functional, whereas local community oriented affects symbolic and social. Meanwhile, social responsibility and employees’ welfare affect all four product associations, as hypothesized. Moreover, functional and symbolic affect only sensory experience; social affects only cognitive simulation; while emotional affects both sensory experience and cognitive stimulation. Ultimately, both sensory experience and cognitive stimulation, which were affected by corporate and product associations, positively influence re-purchase intentions. Research limitations/implications: This empirical research is meaningful in that it provides understanding about SEs from a marketing perspective. It initially provides the re-purchase mechanism for SEs to contribute a theoretical development for the emerging SE context. It also offers insights and managerial implication directions on how to market for the sustainability of SEs.
