This study is a complex type consisting of survey study and self-study. The former investigated elementary teachers' epistemological beliefs on convergence knowledge and teaching. As a representative of the result of survey study I, as a teacher as well as a researcher, was the participant of the self-study, which investigated my epistemological belief on convergence knowledge and teaching and my execution of convergent science teaching based on family resemblance of mathematics, science, and physical education. A set of open-ended written questionnaires was administered to 28 elementary teachers. Participating teachers considered convergent teaching as discipline-using or multi-disciplinary teaching. They also have epistemological beliefs in which they conceived convergence knowledge as aggregation of diverse disciplinary knowledge and students could get it through their own problem solving processes. As a teacher and researcher I have similar epistemological belief as the other teachers. During the self-study, I tried to apply convergence knowledge system based on the family resemblance analysis among math, science, and PE to my teaching. Inter-disciplinary approach to convergence teaching was not easy for me to conduct. Mathematical units, ratio and rate were linked to science concept of velocity so that it was effective to converge two disciplines. Moreover PE offered specific context where the concepts of math and science were connected convergently so that PE facilitated inter-disciplinary convergent teaching. The gaps between my epistemological belief and inter-disciplinary convergence knowledge based on family resemblance and the cases of how to bridge the gap by my experience were discussed.

Traffic jam and congestion in urban areas has caused the need to improve the utility of underground space. In response, research on underground structures is increasingly being conducted. Notably, a double-deck tunnel is one of the most widely used of all those underground structures. This double-deck tunnel is separated by the middle slab into the upper and lower roadways. Both vehicle load and earthquake load cause the middle slab to exhibit dynamic behavior. Earthquake-related response characteristics, in particular, are highly complex and difficult to interpret in a theoretical context, and thus experimental research is required. The aim of the present study is to assess the stability of a double-deck tunnel's middle slab of the Collapse Prevention Level and Seismic Category 1 with regard to the presence of vibration-damping Rubber Bearings. In vibration table tests, the ratio of similitude was set to 1/4. Linings and vibrating platforms were fixed during scaled model tests to represent the integrated behavior of the ground and the applied models. In doing so, it was possible to minimize relative behavior. The standard TBM cross-section for the virtual double-deck tunnel was selected as a test subject. The level of ground motion exerted on the bedrock was set to 0.154 g (artificial seismic wave, Collapse Prevention Level and Seismic Category 1). A seismic wave with the maximum acceleration of 0.154 g was applied to the vibration table input (bedrock) to analyze resultant amplification in the models. As a result, the seismic stability of the middle slab was evaluated and analyzed with respect to the presence of vibration-damping rubber bearings. It was confirmed that the presence of vibration-damping rubber bearings improved its earthquake acceleration damping performance by up to 40%.

Background: Visual inspection of cervix with acetic acid (VIA) is offered at 252 centers in 64 districts of Bangladesh. VIA+ve women are managed at colposcopy clinics of Bangabandhu Sheikh Mujib Medical University (BSMMU) and 14 Medical College Hospitals (MCHs). This research work has been supported by 'UICC Cancer Prevention Campaign' programme. Objectives: This study explored the role of print materials and electronic media to improve cervical cancer screening in the present socio-cultural context of Bangladesh. Methods: This study was performed from January to August 2011 at two upazilas of Bangladesh (Singair with screening facility and Sonargaon without screening facility). Data were collected by focus group discussion (FGD) with women, husbands and community people before and after intervention. Information on cervical cancer screening and VIA camps was disseminated using advertisement through local cable line of the television, microphone announcement, service providers and leaflet throughout the week prior to a VIA camp. Three-day VIA camps were organized at the upazila health complex (UHC) of both upazilas. Quantitative data was gathered from women at the camps on source of information on VIA and the best method of awareness creation. Results: The population was aware of "cancer" and a notable number knew about cervical cancer. Baseline awareness on prevention and VIA was low and it was negligible where screening services were unavailable. Awareness was increased fourfold in both upazilas after interventions and half of the women and the majority of the community people became aware of screening and available facilities. Cable line advertisement (25.5%), microphone announcement (21.4%), and discussion sessions (20.4%) were effective for awareness creation on VIA. Television was mentioned as the best method (37.4%) of awareness creation. Conclusion: Television should be used for nation-wide awareness creation. For local awareness creation, cable line advertisement, microphone announcements and health education at Uthan Baithaks/ EPI sessions can easily be adopted by the government.

A Korean MP3player also has become complex multimedia device which can provide various functions such as DMB, image playback, radio, electronic dictionary, storage device, and Internet. However, these functions are not provided through one-time mediation. Therefore, studying which changes were made for obtaining or installing these functions and what made such changes possible will be a basis to approach the change factors of medium through medium. Ultimately, by enabling to access the factors of cultural and social changes through MP3player, the main point of this study, it will be a methodological attempt to study a social aspect through medium. This study approached re-mediation according to the genealogical change of MP3player. This study researched the change of media through mediation of MP3player, and approached the change in social contextuality through this. The factors for which a medium is changed are various, but in the change of MP3 player there is re-mediation of each medium in addition to technical change. That is, it is deemed that there are 're-mediation among devices' and 'socially contextual re-mediation' in the change through re-mediation of MP3player.

Cities will soon host two third of the population worldwide, and already today 80% of the world energy is used in the 20 largest cities. Urban areas create 80% of the greenhouse gas emission, so we should take care that urban areas are smart and sustainable as implementations have especially here the greatest impact. Smart Cities (SC) or Smart Sustainable Cities (SSC) are the actual concepts that describe methodologies how cities can handle the high density of citizens, efficiency of energy use, better quality of life indicators, high attractiveness for foreign investments, high attractiveness for people from abroad and many other critical improvements in a shifting environment. But if we talk about Entrepreneurship Ecosystem and Innovation, we do not see a lot of literature covering this topic within those SC/SSC concepts. It seems that 'Smart' implies that all is embedded, or isn't it properly covered as brick stone of SC/SSC concepts, as they are handled in another 'responsibility silo', meaning that the policy implementation of a Science and Technology Park (STP) is handled in another governing body than SC/SSC developments. If this is true, we will obviously miss a lot of synergy effects and economies of scale effects. Effects that we could have in case we stop the siloed approaches of STPs by following a more holistic concept of a Smart Sustainable City, covering also a continuous flow of innovation into the city, without necessarily always depend on large corporate SSC solutions. We try to argue that every SSC should integrate SP/STP concepts or better their features and services into their methodology. The very limited interconnectivity between these concepts within the governance models limits opportunities and performance in both systems. Redesigning the architecture of the governance models and accepting that we have to design a system-of-systems would support the possible technology flow for smart city technologies, it could support testbed functionalities and the public-private partnership approach with embedded business models. The challenge is of course in complex governance and integration, as we often face siloed approaches. But real SSC are smart as they are connecting all those unconnected siloes of stakeholders and technologies that are not yet interoperable. We should not necessarily follow anymore old greenfield approaches neither in SSCs nor in SP and STP concepts from the '80s that don't fit anymore, being replaced by holistic sustainability concepts that we have to implement in any new or revised SSC concepts. There are new demands for each SP/STP being in or close to an SC/SCC as they have a continuous demand for feeding the technology base and the application layer and should also act as testbeds. In our understanding, a big part of STP inputs and outputs are still needed, but in a revised and extended format. We know that most of the SC/STP studies claim the impact is still far from understood and often debated, therefore we must transform the concepts where SC/STPs are not own 'cities', but where they act as technology source and testbed for industry and new SSC business models, being part of the SC/STP concept and governance from the beginning.

In order to create a desirable science culture needed in our society, it is necessary to overcome the foreignness of science and technology and to overcome severance from tradition. In this context, this article attempts to understand the characteristics of our traditional science and to explore the possibility of forming a desirable science culture through astronomy, which is an example of traditional science. Thus, this article examined the general characteristics of astronomy that had appeared first in ancient civilization. It also focused on the fact that each civilization has its own unique cultural elements together with astronomical knowledge as a field of science in traditional astronomy. Calendar and lifa(曆法), which are considered science of time, are closely connected with people's daily lives and reveal cultural differences clearly among the subfields of astronomy. In all ancient civilizations, time was represented based on the movements of the sun and the moon, but how time should be concretely represented varied, depending on different cultures. As a result, various calendar system emerged. Throughout East Asia, including our country, the luni-solar calendar was used. The calendar in East Asia, unlike that in the West, was the one derived from the lifa, which was very complex and elaborate astronomical work. The characteristics of the luni-solar calendar can be clearly found in the seasonal customs that represent people's daily lives well; however, lots of so-called superstition are also included in the seasonal customs. For this reason, it is easy to misunderstand that our calendar system is unscientific, or to suspect that our overall traditional science lacks scientific aspects. However, proper understanding of the calendar and the lifa of East Asia can confirm that scientific aspects certainly existed in our tradition. This will be the vital link to tradition that will help overcome the foreignness of today's science and technology.

Purpose - A trading area is very closely related to consumer life. A trading area is a cultural and social space that consumes culture and promotes human relationships as well as an economic space where consumers live their daily lives. In this context, a trading area research should be conducted objectively and empirically because it deals with the activities of consumer's life. The purpose of this study is to identify the intrinsic psychological motivation(push motivation) caused when consumers visit a trading area and to demonstrate how the push motivation for a trading area influence on consumer's flow, satisfaction, revisit intention. Research design, data, and methodology - In order to develop research hypotheses for this study, the development procedures for push motivation scale are as follows; (1) generating initial pool of items based on previous studies, (2) expert judgement to evaluate content and face validity, and (3) assessing convergent and discriminant validity using confirmatory factor analysis. In order to achieve these purposes, online surveys were conducted on frequent or familiar visitors to the trading areas around the Gangnam, Kunkuk University and Hongik University Station. Among the 1,343 questionnaires collected, 1,157 cases were analyzed by using SPSS 22.0 and SmartPLS 3.0 statistical package program, except for 186 responses in which responses were judged to be unfaithful. Results - The push motivation was classified into five sub-dimensions of excitement/stimulus, rest/relaxation, exit/refreshing, knowledge/learning and human relationship promotion as multidimensional and complex factors composed of individual and social-related dimensions. The excitement/stimulus and human relationship promotion of push motivation have positive effects on satisfaction. However, all dimensions of the push motivation have positive effects on flow. And flow has a positive effect on satisfaction and revisit intention. Meanwhile, the mediation test using boostrapping shows that flow plays a full mediating role in the relationship between rest/relaxation, exit/refreshing, knowledge/learning and satisfaction, but a partial mediating rol e between excitement/stimulus, human relationship promotion and satisfaction. Finally, satisfaction plays a partial mediating role between flow and revisit intention. Conclusions - This study shows that the push motivation is multidimensional and compositive depending on the situation of a consumer. In addition, it is found that the human relationship promotion(a social-related motivation) has a much more important effect on flow and satisfaction than other push motivations of individual dimensions. It also shows that satisfaction increases when consumers are being flowed at their visit and degree of revisit intention also grows as satisfaction increases. As implications of this study, a marketer should try to understand consumer's visit motivation at first and then develop factors that increase their flow, satisfaction, revisit intention. It also requires a marketer to approach subjects on a trading area more objectively and empirically based on the psychology and behavior of consumers, in order to establish a proper and efficient strategy on development of a trading area.

The advent of the $4^{th}$ industrial Revolution requires entrepreneurship to the student as one able to produce creative solutions of complex problems embedded in society with active engagement. Maker Education indicates a new educational approach in which students produce a tangible output as a concrete solution to their problems, experiencing spirits of productive failure, sharing and openness with others during the process due to its educational values and effects which are well-matched with entrepreneurship. This study, in this context, aimed to verify the effect of the maker education in the sense of cultivating entrepreneurship: For this purpose, this study conducted a case study of Maker Education to 56 university students during 7 weeks (14 hours) in K university. The results based upon data analysis collected from reflective journals and interviews showed attitude change of the students in terms of entrepreneurship characterized as self-directedness, risk-taking, and creativity. For more active practices of Maker Education in higher education, both instructors' role as the facilitator, and easily and freely accessible Maker Space should be considered.

Respect for human life and respect for human dignity are two basic values to which organized nursing has urged its members to adhere in their service to mankind. Thus it is the nurses’ duty to provide health care in support of sustenance of life and to pay respect for the patient’s right to dignity. In practice, however, nurses may experience dilemmas between these duties much due to the de velopment of modern advanced techniques. These dilemmas have become more complex and difficult to resolve. Nurses are often faced with situations in which the terminally ill refuse professional care, posing serious conflicts between respect for human life and respect for human rights to self-determination. In such cases, resolution of the problem is not a simple matter, thus requires intensive study into the ethical questions related to the situation. The purpose of this study was to identify ethical problems that nurses experience in caring for terminally ill patients and explore the ways to the resolution of problems within the context of the situations. The methodology used for the study was a case study method which ‘New Casuistry’ proposed by Jonsen & Toulmin(1988) and the ‘Specified Principlism’ proposed by Degrazia(1992) as an alternative to old deductive and intuitive method. Cases were developed through semistructured indepth interviews according to the casutistry method. A total of seven nurses were interviewd who were caring for therminally ill patients. Four cases out of a total 14 cases were related to the topic. Through the case analysis it became evident that nurses appreciated other values more often than respect for the patient’s right to self-determination. These other values were convenience and efficiency in nursing practice in case 1, preservation of life above all other values in case 2, provision of nursing care to fulfill the nurse’s professional obligation at most in case 3, and respect for the family’s demand against the patient’s wish in case 4. This study showed that the most important ethical problems were conflict between respect for the patient’s right to self-determination and sustenance of life for the fulfillment of professional obligation. For this problem, benefit /burden analysis from the perspective of the patient and family for the promotion of patient’s wellbeing may be a way to resolve the conflict. Further, through these analysis it was shown that physicians’ and families’ opinions dominated in the decision - making and the opinions of nurses’ and patients’ tended not to be reflected. Thus the patient's right to his or her care was not readily respected. To solve this problem. nurses should make efforts to communicate reciprocally with their patients, family members and physicians in an effort to respect for their patient’s rights to life and diginity from the point of view and values of the patient. It is also important that nurses provide good basic nursing care up to the time of death regardless of decisions about providing or not aggressive treat-ment for chronically and terminally ill patients.

Antenatal care is zoomed toward3 assisting the Individual to achieve safe and wholesome state of health during pregnancy. Nature of fear is assumed to be rooted to complex interaction between past experiences, human relationship and present state of health, however. specific relationship between fear and the variables have not yet been ascertained. This study is designed to investigate the nature of fear of pregnancy, and the correlation between fear and the personal and environmental variables such as personal characteristics past experiences. and psycho-social factors. During the period from October 23 to November 5, 215 pregnant and 104 non-pregnant women of similar chronological are group residing in Seoul were interviewed according to check-list by random General anxiety test, general personality test and test for fear of pregnancy, family according to specific variables such as past experiences of Pregnancy and childbirth, structure of family, family relationship and month of pregnancy was done to the group of pregnant women. To non-pregnant group, general anxiety test was performed to compare with pregnant group. Results of the study are as follows; 1. Hypothesis 1; Degree of general anxiety will be higher e pregnant women compared to that of non-pregnant women. There is no significant difference between the general anxiety of pregnant women and that of non-pregnant women. Therefore, hypothesis I is rejected. 2. Hypothesis 2: Fear of pregnancy and general anxiety will be correlated with personality factors. Through test for fear of pregnancy and general anxiety, a meager contra-correlation between fear and only two personal factors (R and E factor) is revealed but there is no significant correlation between fear and other personal factors (A.S. and T factor). Degree of fear of pregnancy tends to b: higher in the group with low personality factors; responsibility and emotional stability expect the correlation between ascendancy, sociability, and confidence-inferiority. non-significant. Through general anxiety test, level of general anxiety tends to be higher in the group. with low personality factors; responsibility. emotional stability, and confidence except ascendency and sociability, non-significant. Hypothesis 2 is partially supported. 3. Hypothesis 3; General anxiety and fear of pregnancy will be correlated with the past experience-ol pregnancy, and child-birth experience. Though general anxiety test and test for fear of pregnancy, non-significant difference is revealed by P〉.05 level Hypothesis 3 is rejected. 4. Hypothesis 4: General anxiety and fear of pregnancy will be correlated with the month at pregnancy will be correlated with the month of pregnancy. Through tests of general anxiety and fear, significant correlation is revealed degree of fear by-P〈.05 level (CR=1.98) and level of general anxiety by P〈.005 level (CR=3. 11) is higher in the earlier stage of pregnancy. Hypothesis 4 is supported. 5. Hypothesis 5, 6, 7; General anxiety and fear of pregnancy will be correlated with socio-economic status, family structure, and family relationship. Through general anxiety test and tear of pregnancy test, non-significant is revealed by P〉.05 level. Hypothesis 3.6.7 are rejected. Conclusion and recommendation Level of general: anxiety and degree of fear of pregnancy is shown not to be correlated with variables of past experiencers of pregnancy and child-birth. and family factors except the month of - pregnancy. Personal characteristics are shown to be partially contra-correlated meagerly with genera anxiety and fear of pregnancy. This study revealed contrasted results, in regard to presence of correlation between general anxiety and fear of pregnancy to other thesis. In this context. further studies under controlled environment is recommended.
