Purpose - This study aims to explore the success of Lotte Mart in the global market, as well as examining the factors related to its entry methods. Research design, data, and methodology - This study analyzed the differences between Lotte Mart and E-mart in terms of their market entry methods, based on references and secondary data. This study is based on qualitative research that analyzes actual cases. Based on the results, this study analyzed and discussed actual cases based on references and secondary data, including newspaper interviews on Lotte Mart. Results - Lotte Mart succeeded in adapting to local markets it did this by ensuring the use of both mergers and acquisitions (M&As) and greenfield methods. In contrast, E-mart utilized only greenfield methods. Conclusions - The findings of this study may not be generalized to all industries, as only Lotte Mart was examined using the case analysis method. Therefore, the successful market entry modes of various companies should be explored in terms of FDI.

Purpose : The purpose of this pilot experiment was to evaluate early bone response in two types of coated implants using the rabbit tibia model. Materials and Methods : Screw type titanium implants manufactured with a calcium metaphosphate (CMP) coating and hydroxyapatite (HA) coating were placed in the tibiae of 3 New Zealand White rabbits. The bone responses at 2 weeks after insertion were evaluated and compared by histomorphometry. Results : There was no significant difference in bone-to-implant contact between the groups (P>.05). However, some qualitative differences on histologic views were found. Conclusions : CMP-coating is suggested to be the preferred candidate for fast osseointegration over HAcoating.

With the introduction of the e-learning since 2000, the place of the education has not been limited to off-line, but the range of it has become broader in online. The e-learning market has evolved steadily over time. With the advent of the term "Edu-tech", which means a combination of education and technology, various IT technologies have incorporated education. Particularly, the Korean education market collects patterns by computerizing the learning history in classes taught according to curriculums. Because of that environment, various personalized learning services have been developed which maximize the effect of the learning. These services have qualitative differences depending on how many data is accumulated and algorithms are developed for the precise analysis. The purpose of this study is to recognize and data-ize OMR marking by the most suitable method to convert analog data into digital data without harming the Korean education system.

The pyrolytic behavior of vanillin, a flavorant for manufactured cigarettes, was examined to find its contribution to the smoke composition. Vanillin was pyrolyzed at various temperatures (500-$900^{\circ}C$) in a stream of nitrogen. Pyrolytic products at $800^{\circ}C$ were identified with GC/MS. As increasing temperature, pyrolytic products did not appear with qualitative differences. Component analysis of the resulting products showed that 24 compounds were identified. and phenolic compounds were major products. The pyrolytic pathway of vanillin was also discussed.

Today's young generation users are very active in expressing themselves through smart phones, form networks in this cyber space and express their identities freely. Therefore, this study aims to investigate how young people in their 20s are expressing themselves through smart phones and the differences from the attempt of self-expression in the existing cyber space. The research method was an in-depth interview, which was a qualitative research method, aimed at people in their 20s, so that they could freely talk about their thoughts and feelings. In-depth interviews are useful for users' psychological and in-depth analysis of behavior.

We have developed a new method to visualize river networks in tropical rain forests from JERS-1 SAR images. This method compresses river information in an original SAR image to a small image displaying wide rivers as dark objects in real size and narrower rivers as bright objects showing brightness level as an indicator of the discharge. We applied this method to 476 images of Amazon forests, 13 observations for path 415 data and 11 observations for path 416 data between 1993 and 1997. We confirmed that a change observed in a preliminary experiment was certainly a part of seasonal changes. The changes roughly correspond to the monthly precipitation changes. Through a simple digital analysis although qualitative, we also detected subtle but consistent regional differences among minor tributaries that belong to a major tributary basin.

This study aims to compare human resource development by industrial and occupational characteristics of science and engineering graduates. To achieve research objectives, this study analyzed whether differences exist in human resource development, such as participation in vocational training, wage levels, and cuture of talened person preference, by industrial and occupational characteristics. The results showed that workers in engineering fields received more benefits and support compared to those in non-science and engineering field occupations at the quantitative statistics of vocational training and wage levels. On the contrary, according to the qualitative statistics, workers of non-science and engineering field have a culture of talented person preference compared to those in science and engineering occupation.

This study aim is occur in brain CT cause of beam hardening effect and reducing method, We will scan Bone opaque bead phantom on variation of image on the influence factor with equipment called 'Samatom Senation 16' with following listed herein : tube voltage, tube current, slice thickness, gantry angle, base line which affect beam-hardening effect. After that we are going to start Quantitative Analysis resulted in previous scanning and Qualitative Assessment with CT image sheet evaluation. result of quantitative analysis 140kVp $31.56{\pm}2.89HU$ on tube voltage, 150mA $-3.87{\pm}0.12HU$ on tube current, 3mm on slice thickness, and $13.31{\pm}1.03HU$ IOML on gantry angle which was the least beam-hardening effect. Like Qualitative Analysis, we went through Qualitative Assessment and most of valuers got a result of 140kVp on tube voltage, 150mA on tube current, 3mm on slice thickness. As before valuers evaluated gantry angle that scanned image from IOML or OML was the least beam-hardening effect occured. There are meaningful differences when we compare all theses factors statistically(P<0.05). therefore We consider that Minimizing artifact that caused by beam-hardening effect can provide better quality of image to deciphers and patients. if we rise tube voltage in permissible dose limit, set tube current in a limit that does not effect to image quality, use slice thickness too thin enough to harm resolution, use IOML or OML on gantry angle.

This study utilized an analysis method for detecting six microorganisms, such as Actinobacillus actinomycetemcomitans, Campylobacter rectus, Porphyromonas gingivalis, Tannerella forsythus, Treponema denticola, and Prevotella intermedia, triggering periodontal disease, using multiplex real-time polymerase chain reaction (PCR). The analysis including internal control was made by dividing the six species into two groups using four fluorescence dyes, and it was verified that there was no interference or cross-reaction between the target species and different kinds of oral microbial species. Qualitative and quantitative analyses were conducted on each microorganism in various samples, such as saliva and the plaque, using the multiplex real-time PCR and comparative analysis between periodontitis patients and healthy people, revealing obvious differences between them.

This study aimed to develop the components of Korean creativity and to examine differences between responses of Korean and US students. Seven experts were interviewed to establish components of Korean creativity. College students in Korea (1,210) and college students in the US (514) responded to the questionnaire. Analysis was by principal component analysis, independent sample t-test, and qualitative analysis. Results were: (1) five factors of Korean creativity consisted of elaboration, redirection, novelty, understanding-the-new-by-exploring-the-old (UE), and freethinking. (2) Korean students scored higher on elaboration and UE, and American students were better at redirection, novelty, and freethinking. (3) Each of the seven interviewees identified five factors of Korean creativity, but the factors varied according to their fields of expertise.
