A Study on the Consumer Perception and Factor Analysis of Food Tourism / 대한지역사회영양학회지

The purpose of this study is to investigate consumer perception and importance of food tourism properties and performance of the properties in Sangju province of Gyeongsangbuk-do. The study has found that persons who have food tourism experiences (75 persons, 50.7%) had slightly more than not experience persons (72 persons, 48.6%). Additionally, most of the respondents were usually satisfied with the local foods. Also, it was found that food tourism had been taken 1-2 times per 6 months (48 persons, 64.0%) on average, and 135 persons (91.2%) had intention of experiencing food tourism. According to the result of Importance-Performance Analysis (IPA) on consumers' food tourism properties, high importance was on 'There are attractive landscapes.' (4.52 +/- 0.56), 'Accommodations with reasonable price.' (4.18 +/- 0.80), and 'The food of the area is famous.' (4.15 +/- 0.73); and the properties such as 'There are local specialty shops or markets selling local produce.' (3.03 +/- 0.83), 'The climate is temperate.' (3.03 +/- 0.87), and 'There are attractive landscapes.' (3.02 +/- 0.98) showed average performance. A factor analysis about consumers' importances to the food tourism properties shows that the factors were divided into four kinds and each of the factors were named as 'convenience-stable propensity', 'valued-oriented propensity', 'adventurous-aggressive propensity' and 'traditional-active propensity'. Variance ratios of each factor were 22.319%, 10.286%, 8.723% and 6.239%, respectively. According to the result of a reliability analysis, Cronbach's alpha value was 0.8621, implying that reliability of each item was very high. Therefore, it is considered that development of food tourism products and promotion strategies therefore should be designed based on the importance of food tourism properties hereafter.

Biochemical Markers and Health Behavior Related with Bone Mineral Density in Adult Men / 가정의학회지

BACKGROUND: More than half of the causes of male osteoporosis is due to secondary osteoporosis. Therefore, it is important to detect and modify its related factors. The aim of this study was to find related lifestyle factors and biochemical markers with low bone mineral density (BMD) in Korean men. METHODS: A cross-sectional analysis was performed in men aged 40-69 years who visited a hospital for health checkup from January to March 2007. BMD was measured at proximal femur and lumbar spine by dual energy x-ray absorptionmetry. Lifestyle factors were estimated by a self-administered questionnaire and fasting glucose, uric acid, gamma glutamyltransferase, alkaline phosphatase, creatinine, free testosterone, 25-OH vitamin D, urine deoxypyridinoline, osteocalcin were measured. Multivariate logistic regression was used to find the association to the lowest tertile of BMD. RESULTS: A total of 152 subjects were included. After multivariate analysis adjusted with age, BMI, smoking, alcohol and exercise, different factors were correlated with low bone density in each site of femoral neck and lumbar spine. Factors correlated at both sites were BMI and exercise; lower BMI and doing no exercise increased risks of low bone density. Increasing age and alcohol intake > or = 14 drinks/week were associated with lower BMD at femoral neck. The factors associated with lower lumbar spine BMD only were lower level of uric acid and higher level of urine deoxypyridinoline. CONCLUSION: Different factors were associated with low bone density at femoral neck and lumbar spine in men. BMI and exercise were related in both sites; age, alcohol intake, uric acid and deoxypyridinoline were related on either site.

Dietary Intake Assessment by the Number of Chronic Diseases and the Season for Elderly Living in Rural Area

Korea's aging population has been remarkably increased. They want to have not only extension of life expectancy but also improving quality of life. To maintain the quality of life, it is essential to have good nutrition. However, nutritional status of elderly in Korea has problems qualitatively and quantitatively. Risk factors for poor nutrition are advanced age, woman, living alone and low economic status. Another risk factor in rural area is season because seasonal changes can affect food intake of elderly. Thus this study surveyed the health status and dietary intakes of elderly by season in rural area. In this study, the elderly were grouped as group 1 {elderly who have one risk factor for chronic diseases (obesity, hypertension, dyslipidemia, diabetes)} and group 2 (elderly who have more than 2 risk factors). Can-Pro 3.0 was used for dietary data analysis and SPSS 12.0 program was used for statistical analysis. Obesity had the highest percentage 62%, followed by hypertension 59.5%, dyslipidemia 21.5% and diabetes 11.6%. Obesity, hypertension, and dyslipidemia were high in winter and WHR, diabetes and anemia were high in summer. Mean intakes of energy and nutrients were less than RI. Nutrients which were changed most by season were vitamin A and Vitamin C. Intakes of calcium and folic acid were less than recommended in summer. The ratio of CPF for carbohydrate was higher and fat was lower than recommended. In conclusion, the nutrient intake of Group 2 was better in quality but Group 1 was better in quantity. Nutrient intakes were poor in summer. In rural area, more careful nutritional assesment and management are needed for aged population, especially in summer.

The Relating Factor and Quality of Life of Overactive Bladder in Adults / 가정의학회지

BACKGROUND: Overactive bladder syndrome (OAB) is a common disorder in primary care that affects negatively on the quality of life of outpatients. However, little information is available on related factors and the quality of life in adults with overactive bladder. The purpose of this study was to find related factors of overactive bladder and to measure the quality of life in adults with overactive bladder. METHODS: Among the people who visited a hospital in Seoul and Chung-ju for a health examination or primary care between October 1 and December 31, 2008, we selected 327 participants over 20 years old. We measured their Overactive Bladder Questionnaire (OAB-q), took medical history and reviewed their demographic data. The relationship between OAB, other independent variables and health related quality of life (HRQL) were analyzed. RESULTS: Of 327 respondents, the prevalence of OAB in adults was 38 (11.6%). The factors related to OAB were age (P = 0.007), history of prescription for congestive heart failure (P = 0.023), benign prostatic hyperplasia (BPH) (P = 0.002), and depression (P = 0.008). OAB was significantly associated with BPH medication (P = 0.042; OR = 8.757) and depression medication (P = 0.005; OR = 9.977) in multivariable logistic regression analysis. In each T-test analysis, OAB decreased in HRQL. CONCLUSION: OAB is a common disorder in adults, history of BPH medication and depression medication is more common in OAB. The symptoms that were suggestive of OAB were affected negatively on the quality of life in adults. Effective health care polices and prompt management of OAB should be implemented.

Cell type-specific upregulation of myristoylated alanine-rich C kinase substrate and protein kinase C-alpha, -beta I, -beta II, and -delta in microglia following kainic acid-induced seizures

Myristoylated alanine-rich C kinase substrate (MARCKS) is a widely distributed protein kinase C (PKC) substrate and has been implicated in actin cytoskeletal rearrangement in response to extracellular stimuli. Although MARCKS was extensively examined in various cell culture systems, the physiological function of MARCKS in the central nervous system has not been clearly understood. We investigated alterations of cellular distribution and phosphorylation of MARCKS in the hippocampus following kainic acid (KA)-induced seizures. KA (25 mg/kg, i.p.) was administered to eight to nine week-old C57BL/6 mice. Behavioral seizure activity was observed for 2 h after the onset of seizures and was terminated with diazepam (8 mg/kg, i.p.). The animals were sacrificed and analyzed at various points in time after the initiation of seizure activity. Using double-labeling immunofluorescence analysis, we demonstrated that the expression and phosphorylation of MARCKS was dramatically upregulated specifically in microglial cells after KA-induced seizures, but not in other types of glial cells. PKC alpha, beta I, beta II and delta, from various PKC isoforms examined, also were markedly upregulated, specifically in microglial cells. Moreover, immunoreactivities of phosphorylated MARCKS were co-localized in the activated microglia with those of the above isoforms of PKC. Taken together, our in vivo data suggest that MARCKS is closely linked to microglial activation processes, which are important in pathological conditions, such as neuroinflammation and neurodegeneration.

Causes of the Painful Hemiplegic Shoulder and Comparison of the Results of Radiologic Evaluation

OBJECTIVE: The purposes of this study were to investigate the findings of various diagnostic tools for shoulder pain in hemiplegic patients and to compare the results of each diagnostic tool. METHOD: Sixty shoulders in hemiplegic patients with shoulder pain were evaluated by physical examination, visual analogue scale, plain X-ray, arthrogram, ultrasonography and 3-phasic bone scan. RESULTS: The subluxation of shoulder on X-ray was found in 45 patients. The abnormal findings of arthrogram were 39 patients and the most common finding was adhesive capsulitis. The abnormal findings of ultrasonography were 45 patients and the most common finding was supraspinatus tendinitis. In cases of shoulder subluxation on X-ray, manycases were associated with supraspinatus tendinitis on ultrasonography and with adhesive capsulitis on arthrogram. In comparison with the arthrogram and ultrasonography, partial and complete rotator cuff tear findings show consistency. And patients with adhesive capsulitis on arthrogram show significantly high incidence of biceps tendinitis finding on ultrasonography. CONCLUSION: In hemiplegic patients with shoulder pain, the ultrasonography is more valuable and useful as an invasive diagnositc method for the evaluation of rotator cuff tendinitis especially when there is subluxation in X-ray and adhesive capsulitis in physical examination.

Two Cases of Vitamin B12 Deficiency Anemia Combined with Iron Deficiency Anemia / 영남의대학술지

Simultaneous deficiency of Vitamin B12 and iron induces that the bone marrow erythroid megaloblastosis and peripheral blood macroovalocytosis are masked because of countervailing the tendency of iron deficiency to produce hypochromic microcytic erythrocytes. We report two cases of Vitamin B12 deficiency anemia with low mean corpuscular volume (MCV) due to combined iron deficiency anemia with review of literature.

Prevalence of the TT virus viremia in Patients on Hemodialysis and General Populations / 대한진단검사의학회지

BACKGROUND: The TT virus (TTV) is a recently discovered, single-stranded circular DNA virus in the serum of the patients with post-transfusion hepatitis and it is thought to be one of the causative agents of cryptogenic hepatitis. In this study, we evaluated the prevalence and clinical significance of TTV viremia in general populations and patients on hemodialysis. METHODS: Sera of 115 general populations and 69 patients on hemodialysis were examined for TTV viremia by semi-nested polymerase chain reaction using primers deduced from the N22 region. RESULTS: The TTV was detected in 26.1% (18 of 69) of the patients on hemodialysis and was not different from the 20.9% (24 of 115) prevalence in general populations. Two patients on hemodialysis that revealed biochemical evidence of acute hepatitis were the sole TTV infection without other hepatitis virus infection but the mean alanine aminotransferase level was not significantly different according to the TTV viremia. The TTV was persistently detected in the sera of eight of thirteen patients (61.5%) 12 month later without any evidence of hepatitis. CONCLUSIONS: TTV is widespread in general populations and shows similar prevalence in patients on hemodialysis. Viral persistence and nonparenteral transmission may be possible. The relationship between the TTV viremia and hepatitis was not proved.

A Case of Chronic Myelogenous Leukemia with ider(22)(q10)t(9;22)(q34;q11.2) as Clonal Evolution / 대한진단검사의학회지

The ider(22)(q10)t(9;22)(q34;q11.2) is a rare secondary karyotypic aberration of Philadelphia chromosome positive chronic myelogenous leukemia (Ph+ CML) and was associated with disease progression and poor clinical outcomes in most of the previously reported cases. We experienced a case of Ph+ CML with the occurrence of ider(22)(q10)t(9;22)(q34;q11.2) as clonal evolution preceding an hematologic feature of accelerated phase for 3 years. So this chromosomal abnormality was not always correlated with poor prognosis. Relevant literature was reviewed.

A Case of Acute Monoblastic Leukemia with Hexasomy 8 / 대한혈액학회지

Additional copies of chromosome 8 are nonrandom karyotypic aberrations in myeloid malignancies with trisomy 8 being the most common. Hexasomy 8 is extremely rare and only two cases have been reported. We report a case of acute myeloid leukemia with hexasomy 8 as a sole karyotypic aberration by conven-tional cytogenetic analysis. The patient was diagnosed as acute monoblastic leukemia and showed short survival.

Detection of mecA, blaZ and aac(6')-aph(2") gene of staphylococci by PCR / 대한임상병리학회지

BACKGROUND: Staphylococci are major nosocomial pathogens and reveal an increase in resistant strains such as methicillin-resistant Staphylococcus aureus. For treatment of infection and prevention of dissemination, rapid and reliable identification methods are required but the conventional bacterial identification and susceptibility tests require at least 24 hours. In this study, we evaluated the polymerase chain reaction (PCR) of the antibiotic resistant genes by comparing with the disk diffusion susceptibility test for the detection of resistance to penicillin, oxacillin and gentamicin. METHODS: A hundred-thirty-five staphylococci including 95 S. aureus and 40 S. epidermidis were from clinical specimens from June to December 2000. Antimicrobial susceptibility tests were done using the NCCLS disk diffusion method. PCRs were performed with primer sets specific for mecA, blaZ and aac(6')-aph(2"). The species-specific PCR was also used to identify S. aureus and S. epidermidis. RESULTS: All four penicillin-susceptible staphylococci were negative for blaZ and 108 of 131 penicillin resistant-staphylococci were positive for blaZ. The concordance rate for PCR of the blaZ gene and penicillin disk diffusion test was 83.0%. 110 of 115 oxacillin-resistant staphylococci were positive for mecA and all five mecA negative oxacillin-resistant strains were positive for blaZ and have the phenotype beta-Lactamase hyperproducer. One of the oxacillin-susceptible S. aureus was positive for mecA. The concordance rate of PCR for the mecA gene and oxacillin disk diffusion test and those of the aac(6')-aph(2") gene and gentamicin disk diffusion test was 95.6% and 97.8%, respectively. CONCLUSTIONS: The disk diffusion tests misdiagnosed 25% of the mecA negative staphylococci as methicillin-resistant staphylococci (MRS) and lost one of the mecA positive strain. We considered that the detection of the mecA and blaZ gene using the PCR was more useful than the disk diffusion test for detection of methicillin-resistant staphylococci.
