  • The object of this study was to investigate the relationship between stress and the extent of coronary artery stenosis in 101 patients with coronary artery diseases. Global assessment of recent stress(GARS) scale and perceived stress response inventory were used to measure perception for stressors and stress responses. Biological variables such as the extent of coronary artery stenosis, the number of the affected lesions on coronary angiography, serum Low Density Lipoprotein(LDL)-cholesterol, High Density Lipoprotein(HDL)-cholesterol, and total cholesterol were measured in all the subjects. Scores of perceived stress related to changes in relationship and overall global scores on GARS scale had significantly positive correlation with the extent of coronary artery stenosis. On the other hand, scores of percieved stress related to changes in relationship and changes or no changes in routine had significantly positive correlation with the number of the lesions. Scores of perceived stress related to change or no change in routine also positively correlated with serum level of LDL-cholesterol and total cholesterol. In contrast, general somatic symptoms negatively correlated with the extent of coronary artery stenosis. Impulsive-aggressive behavior negatively correlated with the number of the lesions. However, impulsive-aggressive thinking positively correlated with LDL-cholesterol. The above results suggest that perception for stressors may negatively affect the extent of coronary artery stenosis, the number of the lesions, serum LDL-cholesterol and total cholesterol. However, some stress responses showed inconsistent effect on the above biological variables. Thus, strategies designed to modify perception for stressors and some stress responses are likely to help the patients minimize the extent of coronary artery stenosis and prevent the diseases.

  • Since most construction workers comprehend information on work through sight, the importance of safety signs are increasing by the day. In Korea, due to the sharp economic progress and the higher standard of the workforce, since the end of 1980, each year the number of foreign workers entering the country who working simple technical jobs have increased this condition. This study researched safety signs, which are the final accident prevention measures at the workplace. Based on the study, comprehension of the standard safety signs of the Occupational Safety and Health Act (OSHA) was lacking at a level of 2.5. Also, the perception level of the Industry Public Safety Law (38%) was very low. And, it was found that sex and experience or non-experience in safety training was not an issue in the level of understanding. However, when satisfying the standards of the Occupational Safety and Health Act and changing the safety signs, the level of understanding went up to 3.49 and the perception level was increased significantly to 70%. Thus, it is concluded that, since the foreign workers are mainly from non-English speaking countries and because the workers of Korea are not familiar with English, in order to provide proper safety information, there must first of all be simplistic and concise pictograms. This will provide needed information and must be coupled with simple English words that can give additional information to the worker and be effective in helping him understand and perceive the safety sign. Also, it has been determined that the existing forms of safety signs and their effectiveness in industry accident prevention must be reassessed.

  • Background: To evaluate the knowledge, perception and attitudes towards human papilloma virus (HPV) among pre-university students in Malaysia. Study design : In this cross sectional study, between November 2013 to March 2014, in a public university, a convenient sampling method was used. A total of 716 respondents were recruited and interviewed with a set of standard questionnaires for assessment of knowledge, perception and attitudes towards HPV and predictor variables associated with level of knowledge. Results: Almost half (48.9%) of the respondents scored less than 5 and were categorised as having poor knowledge. Three hundred and twelve (43.6%) respondents had moderate knowledge and only 54 (7.5%) respondents exhibited good knowledge with the score of 11 and above. Only 142 (20%) students perceived themselves to be vulnerable to HPV infection though 560 (78.2%) students thought that HPV infection is a serious disease. Perceived benefits and desire to be vaccinated were significantly associated with gender (p=0.000) and knowledge of HPV vaccine and cervical cancer (p=0.000). Conclusions: The level of knowledge regarding HPV among the pre-university students was low. However, student intention for vaccination increased with increasing level of knowledge. Thus, efforts to improve knowledge and awareness should be prioritised to increase uptake of the HPV vaccination programme and hence reduce morbidity and mortality from consequences of HPV infection, including cervical carcinoma.

  • This study was performed to investigate the change in taste perception during aging and its effects on dietary intake in Korean elderly. The subjects were female aged 65 through 90 in the Anyang area, and college women were included as a comparison group . Dietary intake of the elderly(n=155) and young subjects (n=38) was measured by a 3 day diet record. The taste threshold and 'just right' concentrations(JRC) for sweet and salty tastes were assessed by sensory evaluation . Sucrose solution (0.0.,0.4,0.6,0.8,1.0, 1.2%) and salt solution(0, 0.02, 0.03,0.06,0.09,0.12,0.15%) were used to establish thresholds. for JRC assessment, four suprathreshold sucrose concentrations of 5, 8, 11 and 14% in orange-pineapple flavored juice and salt concentrations of 0.20, 0.34, 0.50and 0.75% in beef stock were prepared. Mean intakes of energy, protein , vitamin A, thiamin , riboflavin, niacin ,calcium and iron of the elderly were below the Korean Recommended Dietary allowances. The elderly showed higher taste thresholds than young subjects of both sweet and salty tastes consumed less calories. Needs to bespecified. The older subjects having high threshold or JRCs for sweet and salty tastes consumed fewer calories from protein and fat. Pearson correlation coefficients was between JRC for sweet and salty tastes 0.54(p<0.01). The correlation coefficients between tastes threshold and nutrient intakes were very low for both age groups. Unlike the college women, in the elderly the JRC of sweet taste of the orange-pineapple juice were negatively correlated with intakes of energy, protein, fats, thiamin , riboflavin , niacin ,vitamin C , iron and consumption of meat and egg food groups (p<0.01). In summation age-related alterations in sweet and salty taste perception were observed in the elderly and dietary intakes of the elderly see to be influenced by these taste perception changes.

  • Misinformation and inappropriate use of medication has become one of the most pressing concerns in drug safety. The purpose of this study was to survey public perception on drug safety as well as the channels most relied upon providing such information. The survey was performed for patients or their families visiting pharmacies in a local city in Korea. Analysis was performed from 367 respondents to the survey. The contents of this survey revealed that consumers were aware of the fact that medications should not be taken at any higher dosage or more often than directed by their prescriptions. The survey revealed a general awareness that symptoms might not be relieved immediately by their medications. However, the perception that there could be adverse drug reaction (ADR) at therapeutic dose was low except among the young or highly educated members. Respondents recognized that skin rashes were the most whereas drowsiness was the least common ADR symptom. There was a high awareness of drug-food or drug-drug interactions except in the case of certain nutraceuticals. Doctors and pharmacists were ranked as the most reliable resources to the consumer for providing drug related information. However, public relations or education programs were in need since there were still not negligible numbers of consumers depending on personal experience rather than health professionals.

  • The convenience and flexibility due to the spread of Internet allowed consumers to easily participate in marketing activity. Consumers want to participate in designing, manufacturing, delivering of products and service by expressing their opinions to the companies because they want to buy customized goods where their requirements are incorporated. We can expect that, through this interactive process of customization between consumers and companies, strong relationship quality may be built as a result of the interaction. The main purpose of this study is to examine the influence of consumer perception of customization on relationship quality in the e-business context. To accomplish this purpose, I reviewed the concept of customization, identified the perceptive factors of customization in e-business context (i.e., perception of participation level, assessment of flexibility), and examined the type of customization. Whether customization type generates varying degrees of perception of customization and relationship quality is revealed. As a result, collaborative product/service customization generated the highest relationship quality. Assembled product customization that was built based only on predicted consumer needs without any interaction between consumer and company showed a low level of relationship quality. And this type had no significant difference from standardized products. In short, there is a strong need for e-business companies to interact with consumers to improve relationship quality.

  • Perceptions of Library and Information (LI) professionals in Nigeria and the impact of COVID-19 on libraries, librarians and library services, were studied. The significance of demographic factors on LI professionals' perception of COVID-19 and its impact on libraries was tested. Descriptive survey design and Purpose sampling technique were adopted. LIS professionals in Nigeria constituted the population, and an online questionnaire designed by the researchers through Microsoft Forms was used. Descriptive analysis of respondents' demographic data and their covid-19 perception were presented in frequencies and percentages using tables while multivariate regression technique was used to test the significance of relationship between variables at P < 0.05. Findings revealed that many (61.4%) of the respondents agreed that COVID-19 is real but have personal reservations. However, 47.5% indicated that COVID-19 is a scientific invention. On the impacts of COVID-19 on libraries, the study found that COVID-19 is a game changer that will enhance the creation of new services by libraries, cause the reconfiguration of library space for safe operations in post-COVID, establishment of new rules and regulations, and more reliance on e-resources. On the test of association, educational qualification of respondents had a significant impact on respondents' perceptions that COVID-19 will reduce the use of library print resources (P-value = 0.005, B: 0.38, [95% CI: 0.115 - 0.646]) and that library will create new services to address the changes caused by COVID-19. Also, educational qualification of respondents significantly influenced respondents' perception that COVID-19 is real. The study recommends that libraries should take advantage of the season to innovate, and that public health institutions should continually educate people on corona virus to disabuse people's mind of conspiracy theories.
