Subjective Sensation

Sense of smell, a subjective sensation, has not been studied as much as the other senses hence interpretation of olfactory messages is still not a fully understood process.  Olfactory perception, about which science made some significant advances only in the last 30 years, identifies a chemical substance coming to nose while also remembering past experiences. Therefore, in terms of odor appreciation profile it is important to reveal the difference between individuals as well as societies. The aims of this study are interpretation of EEG data with subjective statements, generation of a common denominator considering the gender variable and determination of odor appreciation profile for the Turkish sample.In this study, subjects who have no detailed information about the olfaction and odor were selected. EEG measurements were of randomly selected thirty six (eighteen female and eighteen male) right-handed, aged 18-28 years university students. Odor panel consists of 13 pleasant smells from different odor families (orange blossom, jasmine, peach, aldehydes, musk, vanilla, sandalwood, grass, amber, bergamot, pine, rose and patchouli). After examination of participants’ demographic characteristics, subjective statements and EEG data during smelling, The Odor Profile of University Students was provided and suggestions were made related to the conclusions. Keywords: Odor Profile, Electroencephalography (EEG), Odor Appreciation.

As a social being, human life continues in communities with other people. Human being is the only entity that communicates with highly complex learned behaviors that include best use of gestures and mimics, advanced reflex and instinct language as well as language. In our study, we wanted to determine the communication skills of university students with their socio-demographic characteristics. Two separate forms were used in the study. The evaluation of the obtained data was done by SPSS (Version 16.0) Statistical Package Program. The target population of the study is composed of students studying at Marmara University. In the direction of the data obtained within the scope of the research it was observed that the communication skills of the students studying in the departments providing health education are higher. University students are encouraged to develop listening skills and create an environment in which they can express themselves better.

ABSTRACT The fractional determination of 17-ketosteroids in the daily urine was performed in nine cases of hyperemesis gravidarum and in four control cases, in the first trimester of pregnancy both before and after corticotrophin administration. The excretion of total 17-KS is similar in the two groups. Only in the hyperemesis group does the excretion of total 17-KS increase significantly after corticotrophin administration. The fractional determination reveals no difference between the two groups of patients with regard to the values of the fractions U (unidentified 17-KS), A (androsterone) and Rest (11-oxygenated 17-KS). The excretion of dehydroepiandrosterone is significantly higher in the hyperemesis group than in the control group. The excretion of androstanolone seems to be lower in the hyperemesis group than in the control group, but the difference is not statistically significant. The differences in the correlation between dehydroepiandrosterone and androstanolone in the two groups is significant. The high excretion of dehydroepiandrosterone and low excretion of androstanolone in cases of hyperemesis gravidarum is a sign of adrenal dysfunction.

AbstractThe paper aims at exploring determinants of the university students' intentions to stay within their university region. At this, we presume that students' career choice motivations are related to their professional intentions, which again, along with demographic characteristics, affect their migration decision. Our analysis is based on a cross-sectional study of 2,353 students from three different higher education institutions, two of them located in Germany and one in Namibia. Results indicate that in Germany migration matters because a considerable proportion of students intend to leave the university region after graduation. At this, we found that the students' geographical provenance exerts the most significant effect on the intention to stay. Moreover, certain professional intentions were directly and some career choice motivations were indirectly linked with the intention to remain at the university location. We present several conclusions and implications.

Method of calculating the index of crisis of gratification has been developed on the basis of the complete survey of 995 students of medical university and 804 students of engineering university, determination of clinical and social parameters and factors related to the process of education in the specialized university. It included: a scale for the assessment of the degree of intellectual intensity, academic performance, stress situations related to the peculiarities of education. Reliable differences in values between groups of healthy students, students with preclinical and clinical forms of mental disorders are revealed as a result of calculation of the index of gratification. The authors conclude that satisfaction with the results of education has a significant impact on the mental health of university students.

The development of modern civilization attests to its decisive role in the progressive development of institutions. They identified the difference between Western civilization and the rest of the world. Confirmation of the institutional advantages of the West was its early industrialization. The genesis and formation of institutionalism in its ideological and conceptualmethodological orientation occurs as a process alternative to neoclassic in the context of world heterodoxia, which quickly spread in social science. Highlighting institutional education as a separate area of sociocultural activity is determined by the factor of differentiation of institutional theory as a whole. A feature of institutional education is its orientation toward the individual and his/her transformation into a personality. The content of institutional education is revealed through the analysis of the institution, which includes a set of established customs, traditions, ways of thinking, behavioral stereotypes of individuals and social groups. The dynamics of socio-political, economic transformations in Ukraine requires a review of the foundations of national education and determination of the prospects for its development in the 21st century in the context of institutionalism.

BACKGROUND Potential is seen in web data collection for population health surveys due to a combination of its cost-effectiveness, implementation ease and the increased internet penetration. Nonetheless, web modes may lead to lower and more selective unit response rates than traditional modes and hence may increase bias in the measured indicators. OBJECTIVE This research assesses the unit response and costs of a web versus F2F study. METHODS Alongside the F2F Belgian Health Interview Survey of 2018 (BHIS2018; n gross sample used: 7,698), a web survey (BHISWEB; n gross sample=6,183) is organized. Socio-demographic data on invited individuals is obtained from the national register and census linkages. Unit response rates considering the different sampling probabilities of both surveys are calculated. Logistic regression analyses examine the association between mode system (web vs. F2F) and socio-demographic characteristics on unit non-response. The costs per completed web questionnaire are compared with these for a completed F2F questionnaire. RESULTS The unit response rate is lower in BHISWEB (18.0%) versus BHIS2018 (43.1%). A lower web response is found among all socio-demographic groups, however, the difference is higher among people older than 65, low educated people, people with a non-Belgian nationality, people living alone and these living in Brussels Capital. Not the same socio-demographic characteristics are associated with non-response in both studies. Having another European (OR (95% CI): 1.60 (1.20-2.13)) or a non-European nationality (OR (95% CI): 2.57 (1.79-3.70)) (compared to having the Belgian nationality) and living in the Brussels Capital (95% CI): 1.72 (1.41-2.10)) or Walloon (OR (95% CI): 1.47 (1.15 - 1.87) region (compared to living in the Flemish region) is only in BHISWEB associated with a higher non-response. In BHIS2018 younger people (OR (95% CI): 1.31 (1.11-1.54)) are more likely to be non-respondent than older people, this was not found BHISWEB. In both studies, lower educated people have a higher change to be non-respondent, but this effect is more pronounced in BHISWEB (OR low vs. high education level (95% CI): Web 2.71 (2.21-3.39)); F2F 1.70 (1.48-1.95)). The BHISWEB study has a considerable cost advantage; the total cost per completed questionnaire is almost three times lower (€41) compared to the F2F data collection (€111). CONCLUSIONS The F2F unit response rate is generally higher, yet for certain groups the difference between web versus F2F is more limited. A considerable cost advantage of web collection is found. It is therefore worthwhile to experiment with adaptive mixed-mode designs to optimize financial resources without increasing selection bias; e.g. only inviting socio-demographic groups more eager to participate online for web surveys while remaining to focus on increasing the F2F response rates for other groups.
