  • The majority of graphs and visuals made publicly available by Thai listed companies tend to be disjointed and minimal. Only a little over fifty percent of the total 478 companies included graphic representations of their business operations and performance in the form of two or three dimensional spreadsheet based graphs in their annual reports, investor relations documents, websites and so on. For novice users, these visual representations are unlikely to give the big picture of what is the company's financial position and performance. Neither will they tell where the company stands in its own operating environment. The existing graphics and visuals, in very rare cases, can provide a sense of the company's future outlook. For boundary users such as audit committees whose duty is to promote good governance through transparency and disclosure, preliminary interview results show that there is some doubt as to whether the inclusion of big-picture visuals can really be of use to minority shareholders. These boundary users expect to see more insightful visuals beyond those produced by traditional spreadsheets which will enable them to learn to cope with the on-going turbulence in today's business environment more quickly. However, the debate is still going on as to where to draw the line between internal or external reporting visuals.

  • Objectives : The purpose of the study is to investigate the oral health behaviors between students studying in Vancouver, Canada and college students in Daejeon, Korea. Methods : A self-reported questionnaire was filled out by 239 students in November, 2013. The questionnaire consisted of oral health behavior including tooth brushing methods between two countries. Chi-square test and t-test were analyzed. The analyses were conducted using R version 2.14.2(R Foundation for statistical Computing, Vienna, Austria). Results : The number of tooth brushing in Korean students was higher than those in Canada. Fifty nine percent of the Koreans brushed their teeth 3 times a day while 62.3% of students in Canada brushed their teeth 2 times a day(p<0.0001). Those who were taught on oral health education tended to brush the teeth more frequently that those who had not. Koreans and Japanese tended to brush teeth more frequently after breakfast than the Taiwanese(p=0.005). Koreans also brushed teeth after dinner more frequently than Japanese, Taiwanese, and other foreigners(p=0.012). Conclusions : This study indicated that Koreans have better oral health behaviors in comparison to students studying abroad.

  • After examining and analysing the medicinal herbs of fifty-three experimental papers, we studied their effects on immediate tumors in specific cancers. We did not study the influence on the life span of general cancerous cells. We looked to see if the combined usage of medicinal herbs and anticancer agents inhibited the tumor cell's growth. The serum test and blood cell count test showed if the medicinal herbs inhibited the side effects of the anticancer agent. The test showed that more than 80 percent of used medicinal herbs, brought anticancer activities. However, anticancer experimental studies using medicinal herbs have draw-backs. First, it is difficult to choose a prescription using the standards of Oriental Medicine because we are testing a mouse not a man. Second, because we only observed the indirect effect on the whole physiological regulation caused by the synergic effects of the complex prescription, we are not able to understand the detailed mechanism of the herbs. Therefore; if the anticancer effect of the herbs is proved by the experiment, we need to research the concrete medical action of medicinal herbs and the immunological analysis of herbal medicines on the body.

  • This study was performed to investigate the frequency of dairy beverage consumption and factors which affect the dairy beverage consumption of women. The subjects were 1,012 females living in Seoul. They preferred milk, yakult. flavored milk, liquid yogurt, semi-solid yogurt, and low fat milk in order of frequency. The consumption of the dairy beverage was not related to season. The respondents knew that the dairy beverages were nutritious and good for their health. More than fifty percent of them answered that dairy beverages tasted good. The consumption of milk and yakult were related with their occupation, habitual aspect, and practical factors. The consumption of liquid yogurt was affected by their family income, habitual aspect, practical factors and familarity with that beverage. The consumption of semi-solid yogurt was affected by their family income, health status, habitual aspect, and practical factors. The consumption of most beverages were affected by the recognition of those beverages rather than by socio-demographic factors. In order to enough drink dairy beverage, nutritional education messages should encourage consumption of dairy beverages. Policies that make students access dairy beverages at school should be promoted.

  • A causal model of organizational commitment on the basis of Western literature was tested with a sample of 1,164 employees from two university hospitals in Korea. The model contains three groups of determinants : environmental variables(job opportunity, spouse support, and parent support), psychological variables(met expectations, work involvement, positive affectivity, and negative affectivity), and structural variables(job autonomy, work unit control, routinization, supervisor support, coworker support, role ambiguity, role conflict, workload, resource inadequacy, distributive justice, promotional chances, job security, job hazarda, and pay). The data were colleted with questionnaires and analyzed with the LISREL maximum likelihood method. It is found that (1) the following variables, listed in order of size, have significant total effects on organizational commitment : job satisfaction, met expectations, supervisor support, job security, routinization, job opportunity, negative affectivity, work involvement, distributive justice, and promotional opportunity, (2) the model explains fifty-nine percent of the variance in organizational commitment, and (3) the link with expectancy theory is justified by the results for met expectations. Two conclusions can be drawn from these findings. First, the model of organizational commitment appears to be generalizable to Korean hospitals. Second, the model of organizational commitment should include such theoretical variables as environmental, psychological, and structural factors.

  • Brown blotch disease in cultivated mushrooms is caused by Pseudomonas tolaasii, which secretes a lipodepsipeptide, tolaasin. Tolaasin is a pore-forming toxin in the cell membranes, thus destroying the fruiting body structure of mushroom. In this study, we isolated pathogenic bacteria from mushrooms that had symptoms of brown blotch disease. In order to identify these bacteria, their 16S rRNA genes were sequenced and analyzed. Pathogenic bacteria identified as Pseudomonas species were thirty five and classified into five subgroups: P1 to P5. Each subgroup showed different metabolic profile measured by API 20NE kit. Fifty percent of the bacteria were identified as P. tolaasii (P1 subgroup). All five subgroups caused the formation of brown blotches on mushroom tissues and the optimum temperature was 25oC, indicating that they may be able to secrete causal factors, such as tolaasin and similar peptide toxins. These results show that there are at least five different pathogenic Pseudomonas species as blotch-causing bacteria and, therefore, strains from the P2 to P5 subgroups should be also considered and studied as pathogens in order to improve the quality and yield of mushroom production.

  • A microbiological study for the isolation and characterization of Leptospira interrogans was performed in an attempt to define the characteristics of Leptospirosis in Korea. The results are summerised as follows. Thirty-five cultures were isolated from 11 patients with leptospirosis and 24 wild rodents captured in Paju area. The isolation rate of Leptospira from wild rodents reached 23.1%. All 35 cultures were identified as Leptospira interrogans by their characteristic morphology and motility in dark field microscopy, pathogenecity in Guinea pig and sensitivity to 8-Azaguanine. Cultures formed diffuse subsurface colonies with hazy margin and were catalase, peroxidase and oxdase positive. The fifty percent lethal dose of isolate HM 4 in Guinea pig was $8.9{\times}10^4$ org. Mouse passage method was sucecssfully applied in maintenance of fresh isolates without any loss of their original virulency.

  • Reproductive dysfunction is a major health concern amongst the inhabitants of Tana River County. An ethno botanical study was conducted in Garsen, Itsowe and Ngao sub divisions of Tana River County to document the utilization of medicinal plants for the management of female reproductive ailments. The target population was practicing herbalists from Pokomo, Ormo and Giryama communities in the study area. Structured questionnaires and focussed group discussions were used to collect data. Forty eight plant species distributed in 40 genera and 29 families were documented as being important for the management of pregnancy related complications, menstrual disorders, infertility, fibroids and as contraceptives. The species most frequently cited by the herbalists were fourteen. Fifty two percent of the plant species were probably being mentioned for the first time as being useful in reproductive health management. In conclusion, Tana River has a pool of TMPs with a wealth of indigenous knowledge that needs to be exploited. The plants used to treat dysmenorrhea for example may be important analgesic agents that need further investigation while those with anti-fertility properties may contain steroidal phyto chemical compounds. Such species therefore need further investigation to establish their efficacy and mechanism of action.

  • The study was undertaken to assess the degree to which subjects were compliant with a specific metabolic diet in a controlled outpatient feeding study. The study consisted of a two-week control period in which subjects consumed a control diet consisting of 38-40% fat, 18-20% protein, 40-42% carbohydrate, followed by a three-week experimental period during which each subject consumed the control diet plus one of the four fiber supplements(20g/4ay) assigned on a random basis on the trust day. All meals were prepared and eaten in a metabolic feeding laboratory, with the exception of Saturday and Sunday meals that were packed for take-out. Fifty-seven healthy adult men, aged 18-65 years participated in the study. Dietary compliance index(CI) defined as the percent deviation of actual consumption from the prescribed food's and unconsumed prepared foods. The CI reflected the additional 'non-prescribed foods' and unconsumed 'prescribed foods'. A CI was calculated for all subjects. A CI of 5% or more was defined as poor compliance. Overall, dietary compliance was substantially improved for the entire group over the course of the study. Significant increase in compliance far energy and macronutrient intake occurred between the baseline and experimental periods. Within a non-obese group, dietary compliance fir energy improved from 5.5% to 3.3% by the end of the study(week 1vs week 5, respectively, p<0.05). However, between non-obese and obese group, dietary compliance was not different. (Korean J Nutrition 31(5) : 957-964, 1998)

  • Four hundred and thirteen oxytetracycline-resistant bacteria were recovered from six freshwater giant prawn farms with a history of oxytetracycline use. Most oxytetracycline-resistant isolates were Gram-negative bacteria. Six groups of oxytetracycline-resistant bacteria were classified using cluster analysis based on a comparison of levels of oxytetracycline resistance. Complex fingerprint patterns were obtained for 71 isolates studied. In general, the band patterns of isolates from different ponds were very similar, and the data indicated that the isolates were closely related. The exploration for cross-resistance found that most of the 71 oxytetracycline-resistant isolates were also resistant to tetracycline and chlortetracycline, but had a relatively low resistance to doxycycline. Many isolates showed higher chlortetracycline resistance than oxytetracycline resistance. Additionally, the oxytetracycline-resistant isolates were examined for the presence of tetracycline resistance (tet) genes. Fifty percent of the isolates carried one of the 14 known tet genes examined. The most common determinants were TetA and TetD. However, TetB, TetC, TetE, TetK, TetL, and TetM were also found with various frequencies.
