OBJECTS AND METHODS: In order to evaluate the relationships between drinking habits and biological and psychosocial characteristics, the authors administrated the questionnaires about drinking patterns and acute physiological and psychological responses after drinking, several psychological scales and ethanol patch test to 94 male medical students in Chosun University. RESULTS: 1) Low consumer group had significantly more severe physiological repondents after drinking in family members than high consumer group(p<.005). 2) Low consumer had significantly more severe acute physiological responses(p<.005) and high consumer group revealed more positive psychological responses after drinking(p<.005). But there was no difference in the degree of negative psychological responses between tow groups. 3) High consumer group had significantly more extroversion tedency(p<.01) and recieved more financial support from family than low consumer group(p<.01). 4) In the results of ethanol patch test. low consumer group showed more positive skin reaction in three test occasions than high consumer grou(p<.005). 5) Also the high consumer group revealed higher scores in factor 1,2,4(alpha=0.005), and 3(alpha=0.01) in comparison of factors of Korean Alcohol Use Inventory. 6) In comparison of drinking habits, low consumer group revealed higher incidence of nearly non-drinkers and sublimatory drinkers. But there were more casulal social drinkers, selcontrolled social drinkers, impusive-binge drinkers, and habitual-excessive drinkers in high consumer group(p<.005). And in drinking patterns, the items of dependence and duration of drinking, daily drinking disposition, preferential beverage, average and maximum drinking amount of each liquor, and magnitude of sips taken were higher in high consumer group. Only one item of interval between sips was longer in low consumer group(p<.005). 7) In comparison of sociodemographic variables, there were more students who were smokers(p<.01), from larger cities and small family(p<.05), and whose parents were well educated(p<.05) but had worse marital realtionship(p<.05) in high consumer group. CONCLUSEION: For better explanation of the etiology and characteristics of alcoholism, we investigated the differences in various aspects between low alcohol consumers and high alcohol consumers in college students. The most evident differences lied in the degree of acute physiological reaction and positive rates of ethanol patch test that strongly suggested the relations with the activty of ALDH. Some differences in psychosocial aspects between two groups were noticed but could not appropriately be explained at this time.

Purpose: Based on a literature review of artificial intelligence (AI) applications within nursing tasks, this study delves into the feasibility of employing AI to improve nursing practice in Korea. Methods: We used "nursing" and "artificial intelligence" as keywords to search academic databases, resulting in 96 relevant studies from an initial pool of 940.After a detailed review, 35 studies were selected for analysis based on nursing process stages. Results: AI improves nursing assessment by enhancing pain diagnosis, fall detection, and movement monitoring in older adults. It aids nursing diagnosis through clinical decision support, risk prediction, and emergency patient triage. Further, it expedites the creation of precise plans utilizing predictive models in nursing planning. AI also forecasts medication errors and reduces the nursing documentation burden for nursing implementation. Additionally, it manages (re)hospitalization risks by assessing patient risk and prognoses in nursing evaluation. Conclusion AI in Korean nursing can enhance assessment and diagnosis accuracy, promote a prevention-focused paradigm through risk prediction, and ease the burden of nursing practice amidst human resource shortages.

Percutaneous coronary intervention (PCI) is used to treat obstructive coronary artery disease (CAD). The role of PCI is well defined in acute coronary syndrome, but that for stable CAD remains debatable. Although PCI generally relieves angina in patients with stable CAD, it may not change its prognosis. The extent and severity of CAD are major determinants of prognosis, and complete revascularization (CR) of all ischemia-causing lesions might improve outcomes. Several studies have shown better outcomes with CR than with incomplete revascularization, emphasizing the importance of functional angioplasty. However, different definitions of inducible myocardial ischemia have been used across studies, making their comparison difficult. Various diagnostic tools have been used to estimate the presence, extent, and severity of inducible myocardial ischemia. However, to date, there are no agreed reference standards of inducible myocardial ischemia. The hallmarks of inducible myocardial ischemia such as electrocardiographic changes and regional wall motion abnormalities may be more clinically relevant as the reference standard to define ischemia-causing lesions. In this review, we summarize studies regarding myocardial ischemia, PCI guidance, and possible explanations for similar findings across studies. Also, we provide some insights into the ideal definition of inducible myocardial ischemia and highlight the appropriate PCI strategy.

Purpose: Asthma is a chronic airway inflammatory disorder and is associated with macrophages. Statin, a well-known lipid-lowering agent, has recently been noted for its anti-inflammatory effect on macrophage. This study was designed to evaluate the antiasthmatic effect of atorvastatin via modulation of macrophage activation by using an animal model of allergic asthma. Methods: Atorvastatin 40 mg/kg was given by gavage once a day for 3 days before challenge of ovalbumin (OVA); airway hyperresponsiveness (AHR), airway inflammatory cells, and cytokines were evaluated in the murine asthma model. The direct effect of atorvastatin on the activation of macrophages In vitro was determined using the alveolar macrophage cell line CRL-2456. Results: Administration of atorvastatin reduced the numbers of total inflammatory cells, macrophages, and eosinophils as well as lung histology enhanced in the murine asthma model. AHR measured by enhanced pause was significantly reduced after atorvastatin administration in the murine asthma model (P< 0.05). Atorvastatin administration resulted in the reduction in serum OVA-specific IgE levels and the increase in serum OVA-specific IgG2a levels (P< 0.05). The mRNA levels of Ccr3, Il-17, and Muc5ac enhanced by OVA challenge were decreased by treatment with atorvastatin (P< 0.05). Along with these improvement in allergic inflammatory changes, the population of CD11c-CD206+ macrophages as well as the expression of Ym-1 and Relm-α in the lungs were reduced with atorvastatin (P< 0.05). In vitro test with CRL-2456 showed that atorvastatin reduced the expression of Cd206, Arg-1, and Fgf-2 induced by IL-4 stimulation (P< 0.05). Conclusion This study highlighted the antiasthmatic effect of atorvastatin on the suppression of M2 macrophage activation in allergic asthma.

OBJECTIVE: A genetic predisposition is widely accepted in schizophrenia. This study was intended to find any association of HLA-DRB1 alleles with Korean schizophrenics and thereby compare the results of other ethnic groups. METHODS: The subjects were 70 unrelated Korean patients. Low and high resolution typing of HLA-DRB1 alleles were performed. The comparison groups were 2,000 unrelated healthy Koreans for low resolution HLA-DR and 229 unrelated healthy Koreans for HLA-DRB1 alleles. RESULTS: Gene frequencies of HLA-DR11(patients 9.0%, healthy control 3.8%, p=0.005) and HLA-DRB1*1101(patients 9.0%, healthy control 1.8%, p< .001) were significantly higher in Korean schizophrenics. CONCLUSIONS: The frequency of HLA-DR11 (HLA-DRB1*1101) is significantly higher in Korean schizophrenics than in healthy Koreans. HLA-DR4 and HLA-DR1, which were known to be associated with Caucasian and Japanese schizophrenics, respectively, did not show statistical association with Korean schizophrenics. This association need to be reassured through further studies with families or association study with larger numbers of subjects.
