UBVI CCD Photometry of the Open Cluster NGC 4609 and Hogg 15
UBVI CCD photometry is obtained for the open clusters NGC 4609 and Hogg 15 in
Crux. For NGC 4609, CCD data are presented for the first time. From new
photometry we derive the reddening, distance modulus and age of each cluster -
NGC 4609 : E(B-V) = 0.37 +/- 0.03, V_0 - M_V = 10.60 +/- 0.08, log tau = 7.7
+/- 0.1; Hogg 15 : E(B-V) = 1.13 +/- 0.11, V_0 - M_V = 12.50 +/- 0.15, log tau
<= 6.6. The young age of Hogg 15 strongly implies that WR 47 is a member of the
cluster. We have also determined the mass function of these clusters and have
obtained a normal slope (Gamma = -1.2 +/- 0.3) for NGC 4609 and a somewhat
shallow slope (Gamma = -0.95 +/- 0.5) for Hogg 15.Comment: 12 pages, 14 figures, JKAS, in pres
Visible success and invisible failure in post-crisis reform in the Republic of Korea : interplay of the global standards, agents, and local specificity
The reform package in post-crisis Korea was one of the most comprehensively designed and decisively implemented. Though impressed by the quick recovery, many are now raising doubts about real changes in the economy, as the result of a cost-benefits analysis: While the business climate is more stable and supportive, the economy is suffering from weak investment and rising unemployment. This study views the Korean story as one of"visible success and invisible failure,"based on the following findings: First, while some new laws were enacted and several quantifiable targets met, little real progress was made in changing institutional conventions, habits, and beliefs, such as enhancing transparency in management or trust in labor relations. Second, the reform process involved tension between global standards and local specificity, which accounts for the mixed results. Third, special interest politics at the implementation stage, plus the complexities caused by increasing democratization and globalization, have undermined the authorities'implementation capacity, which accounts for uneven outcomes of the reform. While globalization necessitates increasing flexibility, Korean managers are now facing much stronger labor unions. The outcome is not a fully flexible but segmented labor market, divided between the core, unionized workers and unorganized peripheral workers, and between the one overprotected and the other underprotected. Fourth, it is important to have an effective system of legislative bargaining to help resolve disputes. Only with this institutional vehicle will special interest groups reach some consensus. Korea tried to overhaul its financial system and achieve substantial financial liberalization in the early 1990s but those attempts were partly aborted and partly distorted, which paved the way for the financial crisis in 1997. This was due to the lack of clear consensus, without which reforms are more likely to be aborted or be unsuccessful. Fifth, implementation problems stem from institutional complementarities and inappropriate sequencing. One logical sequence might be banking reform, corporate governance, labor relations, and then finally business restructuring. Now, an emerging question is whether the reform blueprint was right. Post-crisis Korea just tried to be more market- or Anglo-Saxon model-oriented without paying attention to growth potential. While firms have now lowered their debt ratios, they are not borrowing to fund investments. The issue of right or wrong blueprint underscores the need to define the reform goal correctly. The goals of reform should not just be a move toward a market-oriented economy but toward a growth-oriented one or a pro-growth market-oriented one.Environmental Economics&Policies,Banks&Banking Reform,Children and Youth,Economic Theory&Research,National Governance
Effects of medical history and clinical factors on serum lipase activity and ultrasonographic evidence of pancreatitis: Analysis of 234 dogs
Background: Lipase measurements and ultrasonographic (US) evidence of pancreatitis correlate poorly.
Objectives: Identify explanations for discrepant lipase and pancreatic US results.
Animals: Two hundred and thirty-four dogs with gastrointestinal signs.
Methods: A retrospective study was conducted, in which lipase activity and US were performed within 30 hours. Medical history, clinical examination results, lipase activity, and US results were recorded.
Results: Lipase and US results were weakly correlated (rs = .25, P 2 days, 118 U/L; P = .03; ≤7 days, 334 U/L; >7 days, 99 U/L; P = .004), but US was not significantly more frequently positive. For both cut-offs (>216/≤216 U/L, >355/≤355 U/L; reference range, 24-108 U/L), median disease duration was significantly shorter (3 vs 4 days) with higher lipases. Previous pancreatitis episodes were significantly associated with an US diagnosis of pancreatitis (P = .04), but median lipase activities were not significantly higher (386 U/L vs 153 U/L; P = .06) in these dogs. Pancreatic US was significantly more often positive when the request contained "suspicion of pancreatitis" (P < .001) or "increased lipase" (P = .01). Only changes in pancreatic morphology, echogenicity, and peripancreatic mesentery were significantly associated with a positive US diagnosis, and also had significantly higher lipase activities.
Conclusions and clinical importance: Duration of clinical signs before presentation differently affects laboratory and US evidence of pancreatitis. Previous pancreatitis episodes and information given to radiologists influence US results. These findings can be helpful for future studies on pancreatitis in dogs
A Descriptive Study on the Extent of Dietary Information Obtained during Consultations at a Veterinary Teaching Hospital
The majority of dogs with chronic idiopathic gastrointestinal (GI) disease respond to diet. So far, no study has assessed how much dietary information is obtained during consultations. We retrospectively evaluated what dietary information was available from dogs presenting to our Gastroenterology (GE), and Internal Medicine (IM) Service between 10/2017 and 01/2020. Data from 243 dogs presenting for first GE consultations were compared to 239 dogs presenting with chronic GI signs for first IM consultations. Referrals comprised 131 (54%) GE dogs and 112 (47%) IM dogs. Referral documents specified the previously fed diet in 53/131 (40%) GE and 14/112 (13%) IM dogs. No dog had received more than one previous diet trial for chronic GI signs. Irrespective of referral status, diet trials had been performed in 127/199 (64%) GE, and 56/156 (36%) IM dogs. The specific diet fed at the time of consultation could only be named by 106/199 (53%) GE and 40/156 (26%) IM dog owners. Data on response to subsequent newly prescribed diets were available from 86 GE dogs and 88 IM dogs. A positive response to diet was noted in 50/86 (58%) GE and 26/88 (30%) IM dogs. A further 23/35 (66%) GE dogs and 12/21 (57%) IM dogs responded positively to a second diet trial, and 4/9 GE dogs (44%) and 6/7 (86%) IM dogs responded positively to a third diet trial. In conclusion, overall dietary information gained from referring veterinarians and owners was often incomplete. More dietary information could be gained during GE consultations compared to IM consultations for chronic GI signs. A positive response to diet can still be seen after two diet failures. Further studies will help to ascertain if the percentage of diet-responsive GI disease increases when more complete dietary information is obtained at the time of consultations

Prevalence of inflammatory versus neoplastic lesions in dogs with chronic gastrointestinal signs undergoing gastroduodenoscopy: 195 cases (2007–2015)
Objectives: Prevalence of inflammatory enteropathy versus lymphoma in dogs undergoing gastroduodenoscopy has not been evaluated. This retrospective study assessed outcome from 195 client-owned dogs scheduled to undergo upper gastrointestinal endoscopy as the next diagnostic step.
Material and methods: Cases were grouped into the following diagnoses according to WSAVA guidelines: lymphoplasmacytic enteritis (LPE), eosinophilic enteritis (EE), mixed-cell enteritis (ME), histologically normal biopsies (N), and lymphoma (L). Clinical signs, and preendoscopic results from laboratory and ultrasonography examinations, were compared among groups.
Results: LPE was diagnosed in 133 (68%), EE in 17 (9%), ME in 9 (5%), 32 (16%) dogs had histologically normal biopsies. Four (2%) dogs were diagnosed with lymphoma. Vomiting was the most frequent clinical sign (61%), followed by weight loss (43%), and diarrhea (39%). Vomiting also predominated when looking at individual histological disease categories, however clinical signs did not differ significantly between groups. Dogs with lymphoma were more likely to have ultrasonographic abnormalities, had significantly lower haematocrit, albumin and total protein concentrations compared to dogs with LPE and histologically normal biopsies.
Clinical significance: Lymphoma was rarely found in this group of dogs with nonspecific results of pre-endoscopic work-up. Our results provide first reference for clinicians when discussing the possibility of a step-up therapeutic approach (such as multiple dietary trials) with owners before pursuing endoscopy. Understanding the likelihood of finding lymphoma is important in that histologic documentation of inflammatory enteropathy alone has limited therapeutic consequences. Future studies are needed to validate these findings in dogs undergoing combined upper and lower gastrointestinal endoscopy and biopsies
