Due to the potential growing capability that reflects future value, the market value of internet business companies (IB) are still evaluated high although major players like Amazon continuously suffer losses. Then, how do investors valuate the potential growing capabilities given that traditional financial/accounting based valuation approaches seem to be inappropriate for IB. This study attempts to provide an answer to this issue. We, therefore, analyzed the predictability of various accounting and non-accounting variables for IB value. These include book value, net income, unique visitors, page view, reach rate, public float and institutional holdings. Because of being in infant stage and difficulties in obtaining necessary web traffic data, sample of 20 pure IB were selected from Korea Stock Exchange Market, KOSDAQ, and informal market. The results of this study showed that web traffic date had the strongest relationship with IB value. In particular, unique visitors and reach rate were found to be best predictors for IB value while page view was reasonable indicator. Interestingly, net income was not found to related to IB value. This calls for an attention to the typical characteristics of IB that my hinder the usage of traditional valuation approaches for IB. Another results revealed that none of both public float and institutional holdings was significantly associated with IB value, indicating market’s supply-demand factors were less important than traffic information.

In an information-oriented and internalized society of the future, the quality and price of goods made by each country will be equalized. That eliminates competition. But the design and appearance of products is an important factor in international competition. Indeed, design symbolizes a country's culture visually, and it can show the cultural identity and originality of a nation in international society. And that will play an important part that can contribute to creating added value. It is necessary to revive our people's old lyrical stories which are far away from our memory, and we badly need design development to revive traditional cultural merchandise through visual modernization. Among various Korean cultural inheritances, lotus is often seen in tiles, porcelains and folk stories. In this study, I chose lotus as the subject material of textile design development, and my intention for this study is to reflect Korean traditional cultural value as much as I can, and to develop textile design of Korean images by adding modern scenes. For that, first I researched lotus pattern materials and examples of cultural merchandise.

Bacteria from the genus Lactobacillus are important for the production of fermented food and dairy products, and as symbionts in human and animals. Lactobacillus acidophilus has widely been used in the production of yogurt, health foods, and even medicines. The efficacy of L. acidophilus has been proven with regards to the reduction of cholesterol, prevention and treatment of diarrhea, modulation of the immune system, suppression of cancer, etc. Using molecular biology tools, Lactobacillus acidophilus has now been reclassified into six species: L. acidophilus, L. amylovorus, L. crispatus, L gallinarium, L. gasseri, and L. johnsonii. Thus, since L. acidophilus has now been marked as a newly defined species, caution is advised when reading future publications regarding this bacterium. In this article, the results of the reclassification of L. acidophilus are mentioned after an analysis of its field inheritance was performed by my research team. Especially, L. amylovorus KU4 (formerly named as L. acidophilus KU4; KCCM 10975P) is a novel probiotic strain that is isolated from humans; it has the ability to reduce cholesterol. It has also been reported as a microorganism that effectively inhibits the growth of pathogenic E. coli. However, this Korean patent (No 10-1541280) refers to a strain obtained from calves; the origin of this strain was incorrectly labeled. Furthermore, after the discovery of L. acidophilus in 1900, its role in intestinal microbiological research was described and its utilization as a probiotic was presented.

This study investigated the characteristics of science imaginary pictures drawn by elementary school students and their perceptions of science imaginary drawing. To do this, $5^{th}$ graders (N=107) were selected from 1 elementary school in Gangwon province and were administered the questionnaires. Some of them were also interviewed deeply. The analyses of the results indicated that most students drew science imaginary pictures in 'land' or 'universe' of 'future' than non-science imaginary pictures. In the academic field, 'machine' was most frequently included in their pictures, and 'earth science' or 'building and traffic' was also frequently included. In addition, half of the pictures included two or more fields. Many students perceived positively the educational benefits of science imaginary drawing upon cognitive, affective, and aesthetic aspects. However, they also had several difficulties in the processes of scientific imaginary drawing such as 'difficulties in using artistic skills', 'difficulties in selecting the subject', 'difficulties in imagining', and 'difficulties in expressing my thoughts to pictures'. Educational implications of these findings are discussed.

Also, I intend to print them on fabric, and apply them to cultural merchandise including scarves and ties, by using digital textile printing systems. The reasons for doing so, are to create high added value, and to let other peoples of the world, know about our excellent culture.

Background: lung cancer (LC) is the fifth of the 10 leading causes of death in the world. LC is in first place for cancer-related mortality for both males and females in Taiwan. It is one of the most difficult cancers to treat and is often diagnosed at a late stage. Patients with stage IV are often unprepared for the diagnosis. Materials and Methods: To explore lived experience among patients newly diagnosed with lung adenocarcinoma stage IV within one year. Results: Twelve participants were recruited in this study. Content analysis of the interviews revealed four themes: (1) emotional roller coaster, (2) trying to find out causes, (3) adjusting my lifestyle, and (4) cancer fighter. Conclusions: This study provides new insight into the experiences of lung cancer patients y with newly diagnosed lung adenocarcinoma stage 4. These results will inform future supportive care service development and intervention research for patients with advanced stage cancer.

Graphene has recently been a subject of much interest as a potential platform for future nanodevices such as flexible thin-film transistors, touch panels, and solar cells. And chemical vapor deposition (CVD) and related surface segregation techniques are a potentially scalable approach to synthesizing graphite films on a variety of metal substrates. The structural properties of such films have been studied by a number of methods, including Raman scattering, x-ray photoelectron spectroscopy (XPS), atomic force microscopy (AFM), and transmission electron microscopy (TEM). An understanding of the structural quality and thickness of the graphite films is of paramount importance both in improving growth procedures and understanding the resulting films' electronic properties. In this study, we synthesized the few-layered grapheneunder optimized condition to figure out the growth mechanism seen in CVD-grown graphenee by using various electron microscope. Especially, we observed directly film thickness, quality, nucleation site, and uniformity of grpahene by using AEM. The details will be discussed in my presentation.

Purpose : This study develops a substantive theory on the recipients' experience of adapting to a permanent pacemaker. Method : The study used the grounded theory method developed by Strauss and Corbin (1998). The participants of the study were 13 adults who had received a permanent pacemaker during the previous year. The study addressed the research question "what is the experience of adaptation in people who had received permanent pacemakers?" From October 2016 to March 2017, data were collected from the participants through in-depth interviews. Results : The core category indicating the essence of the adaptation experience was shown to be "accepting the pacemaker as part of my body and living in line with it." Conclusions : In nursing practice, the results of this study will assist nurses in improving their communications with and developing guidelines or interventions for their clients who have received permanent pacemakers. In the field of nursing education, this study is expected to provide a framework to understand the experiences of future nurses and other healthcare workers working with permanent pacemaker recipients.

The major objective of this study is to analyze the water balance of the Keumgang Estuary Reservoir in the Keum River basin. This basin is one of the catchment area which water utilization is very complicated. For the study of this area, this paper is to evaluate the monthly river-inflow of the Keumgang Estuary Resorvoir. Here, two approach methods are proposed which can take care of the natural and the low flow. The results are as follows. The natural flow at the Keumgang Estuary Reservoir during the wet season was decreased to 8.4% and increased from 0.4% to 17.6% during the dry season by the effects of Deachung Reservoir at the upper basin. The monthly fluctuation of the low flow during My-June varies to a great extent, when large amounts of irrigation water are required.

Dating and dosimetry using electron spin resonance (ESR) in 20th Century developed at both Yamaguchi University and Osaka University have been reviewed with emphasis on new prospects and strategies in 21th century. Natural radiation have been generating radicals that accumulated in archaeological and geological materials. ESR detects these radicals and the ESR signal intensity is proportional to the radiation dose and therefore the age. The assessment of the total dose of natural radiation and the annual dose rate give their ESR ages. The ESR dating of stalactites and stalagmites ant Akiyoshi cave in Yamaguchi prefecture in 1975 was extended to anthropological dating using bones and tooth enamel excavated in Greek Petralona cave. Fossils of shells and corals gave the ages of marine terraces and sea-level changes. Quartz grains gave the ages of geothermal alteration and fault movements. Future ESR dating of ices at outer planets anf their satellite are also investigated as basic studies for ices od $H_2O,\;CO_2,\;SO_2$ as well as terrestrial hydrates in laboratory. Atomic bomb radiation dosimetry at Hiroshima and Nagasaki using ESR lead to the dosimetry of personnel, Chemobyl and JCO criticality accidents. Monitoring of radiation dose with sensitive materials with tissue equivalence are being developed. finally a new scanning ESR imaging apparatus (a near field microwave microscope) developed in our laboratory gave ESR images of Radicals from fossils to Si-CVD and diamond films as summarized in my book in 2002.
