We study the Landau-Ginzburg mirror of toric/non-toric blowups of (possibly non-Fano) toric surfaces arising from SYZ mirror symmetry. Through the framework of tropical geometry, we provide an effective method for identifying the precise locations of critical points of the superpotential, and further show their non-degeneracy for generic parameters. Moreover, we prove that the number of geometric critical points equals the rank of cohomology of the surface, which leads to its closed-string mirror symmetry due to Bayer's earlier result.

The occurrence of Helicobacter pylori(H.pylori) and its relationship with gastric mucosa were studied by light and electron microscopy and culture of biopsy specimens from gastric mucosa of 160 patients with upper gastrointestinal symptoms. H. pylori were present in 96.6% of patients with active chronic gastritis, 100% of patients with duodenal ulcer and 76.9% of patients with gastric ulcer, while present in only 6.3% of individuals with histologically normal gastric mucosa. The bacteria colonized the antral mucosa more frequently than the body or than the duodenal cap mucosa. The bacteria were rarely seen in the intestinalized epithelium per se, but there was no significant difference in prevalence of H. pylori between gastritis with intestinal metaplasia and gastritis without intestinal metaplasia. H. pylori could be seen in close association with the surface of gastric epithelial cells below the mucus layer without evidence of intracellular parasitism, All of the strains tested were susceptible to penicillin, erythromycin, and most of them susceptible to tinidazole and bismuth salts. It is concluded that H. pylori are highly associated with gastritis and peptic ulcer diseases and its prevalence rates in patients with those diseases is higher than in developed countries. This strong association of H. pylori infection with gastritis and peptic ulcer diseases suggest a possible etiologic role for the bacterium in those diseases.

A 28-year-old man developed asthma 10 years after working in a metal-plating factory. Recordings of peak expiratory flow rates showed increased variations after exposure at work. Allergy prick skin tests elicited an immediate reaction with nickel sulfate at a concentration of 1 and 10 mg/ml, and with zinc sulfate at a concentration of 10 mg/ml. Inhalation challenges with nickel sulfate and zinc sulfate produced bronchial obstructions. Thus, we concluded that this was a case of asthma caused by nickel sulfate and zinc sulfate.

ObjectivesZZThe aim of this study is to develop guidelines for psychosocial treatment of alcohol use disorder. MethodsZZAccording to the ADAPTE manual, the Korean alcohol use disorder treatment guidelines were developed by the guideline development committee. Recommendations from foreign guidelines were evaluated regarding the applicability and acceptability to domestic circumstances. In addition, a survey from experts was conducted, along with a review of Korean literature. By these means, recommendations of psychosocial treatment for alcohol use disorder were established. ResultsZZThe main findings of the survey were as follows : 1) Although Group therapy was not recommended by foreign clinical guidelines, it was considered as a first-line treatment by Korean experts. 2) Among many psychosocial treatment programs, cognitive behavior therapy (CBT), coping skills training, 12-step facilitation, and Group therapy were commonly used programs in Korea. Finally, the following treatment methods were selected for recommendations : Group therapy, motivational enhancement treatment, CBT, behavioral self-management, alcoholic anonymous, 12-step facilitation, psychodynamic psychotherapy, psychoeducational intervention, continuous case management, and community residential rehabilitation program. ConclusionZZJust as in treatment of chronic diseases such as hypertension, continuity is important for management of alcohol use disorder. Therefore, not only pharmacological treatment but also psychosocial treatment should be provided comprehensively after treatment of acute withdrawal symptoms.
