Today's liquor culture in Korea is basically divided into a general liquor culture and a functional liquor culture. In particular, the market of the latter has been going through a rapid change. In the previous days, it was a crop for a special purpose or a fruit which was mostly used to make liquor but now, many other regular crops are being used in the liquor market. At present, while the demand for Makgeolli has risen sharply, the designs of Makgeolli bottles have never satisfied needs from consumers nor the trends in the consumer market. As a result, Makgeolli industry should come up with new designs for the bottles immediately if it dose not want to lose in a competition with other liquor products. The study has looked into existing designs of Makgeolli bottles, investigating how the designs have changed over the past years and how competitive they are in the market. Based on results from the investigation, the study focuses on finding out designs which would fit the trends in the consumer market to develop Makgolli bottles which would be equipped with both functionality and practicality. In other words, to make Makgeolli survive in these rapid changes in the liquor market, the study works on offering a Makgeolli bottle design which is appropriate for certain characteristics of Makeolli and also competitive over other liquor bottles.

As advances in computer technology, dissemination of smartphones and tablet PCs has increased and digital media has become easily accessible. The performance of computer hardware is improved and the form of hardware is changed, but basically the change in mechanism was not occurred. Typically, the data used in the program is resident in memory during the operation because of the operating system efficiency. So, these data in memory is accessible through the memory dumps or real-time memory analysis. The user's personal information or confidential data may be leaked by exploiting data; thus, the countermeasures should be provided. In this paper, we proposed the method that minimizes user's data leakage through finding the physical memory address of the process using virtual memory address, and initializing memory data of the process.

The objective of this study was to evaluate the characteristics of the fashion narrative from the commercial and artistic viewpoints by identifying and evaluating the attributes of the fashion narrative and analyzing the fashion narrative focusing on various cases according to fashion media. Louis Vuitton, a brand of the Louis Vuitton $Mo{\ddot{e}}t$ Hennessy (LVMH) group that operates the entire fashion community platform, is recognized as an influential luxury company with enormous capital and capabilities. This study targeted Louis Vuitton to examine the fashion narrative. The common results of Louis Vuitton's fashion narrative according to the communication platform are as follows. First, it emphasizes well-designed craftsmanship and artistry to convey the value and meaning of the brand. Second, it expresses the lifestyle of the bourgeoisie using traveling for finding life purpose, nature, and freedom as common denominators. Louis Vuitton connects, shares, and engages with customers by crossing the communication platform and trying multi-sensory changes based on the fashion narrative of the 'artification' message encompassing craftsmanship, innovation, and travel. The fashion narrative of Louis Vuitton applies tools (e.g., design, direction, stage, and props) differently according to the nature of media. In other words, the fashion narrative in the form of transmedia storytelling is a marketing communication strategy that indicates the representation means and direction of a brand's goals by remediating the brand narrative in various ways through the communication platform.

New concepts and ideas often result from extensive recombination of existing concepts or ideas. Both researchers and developers build on existing concepts and ideas in published papers or registered patents to develop new theories and technologies that in turn serve as a basis for further development. As the importance of patent increases, so does that of patent analysis. Patent analysis is largely divided into network-based and keyword-based analyses. The former lacks its ability to analyze information technology in details while the letter is unable to identify the relationship between such technologies. In order to overcome the limitations of network-based and keyword-based analyses, this study, which blends those two methods, suggests the keyword network based analysis methodology. In this study, we collected significant technology information in each patent that is related to Light Emitting Diode (LED) through text mining, built a keyword network, and then executed a community network analysis on the collected data. The results of analysis are as the following. First, the patent keyword network indicated very low density and exceptionally high clustering coefficient. Technically, density is obtained by dividing the number of ties in a network by the number of all possible ties. The value ranges between 0 and 1, with higher values indicating denser networks and lower values indicating sparser networks. In real-world networks, the density varies depending on the size of a network; increasing the size of a network generally leads to a decrease in the density. The clustering coefficient is a network-level measure that illustrates the tendency of nodes to cluster in densely interconnected modules. This measure is to show the small-world property in which a network can be highly clustered even though it has a small average distance between nodes in spite of the large number of nodes. Therefore, high density in patent keyword network means that nodes in the patent keyword network are connected sporadically, and high clustering coefficient shows that nodes in the network are closely connected one another. Second, the cumulative degree distribution of the patent keyword network, as any other knowledge network like citation network or collaboration network, followed a clear power-law distribution. A well-known mechanism of this pattern is the preferential attachment mechanism, whereby a node with more links is likely to attain further new links in the evolution of the corresponding network. Unlike general normal distributions, the power-law distribution does not have a representative scale. This means that one cannot pick a representative or an average because there is always a considerable probability of finding much larger values. Networks with power-law distributions are therefore often referred to as scale-free networks. The presence of heavy-tailed scale-free distribution represents the fundamental signature of an emergent collective behavior of the actors who contribute to forming the network. In our context, the more frequently a patent keyword is used, the more often it is selected by researchers and is associated with other keywords or concepts to constitute and convey new patents or technologies. The evidence of power-law distribution implies that the preferential attachment mechanism suggests the origin of heavy-tailed distributions in a wide range of growing patent keyword network. Third, we found that among keywords that flew into a particular field, the vast majority of keywords with new links join existing keywords in the associated community in forming the concept of a new patent. This finding resulted in the same outcomes for both the short-term period (4-year) and long-term period (10-year) analyses. Furthermore, using the keyword combination information that was derived from the methodology suggested by our study enables one to forecast which concepts combine to form a new patent dimension and refer to those concepts when developing a new patent.

The purpose of this study was to examine whether the Marital Satisfaction Scale(M.S.S) is properly applicable to Korean couples and further to be devoted to the designed of a marital satisfaction scale for Korea. The scale employed in this study was a Korean adaptation of the M.S.S., which originally included 73 items but was reduced to 48 through a study of its validity by Bowden. This scale was administered to 420 couples. One kindergarten, two elementary schools, one middle school, and four high schools, all of them located in Seoul or its satellite cities were selected for the present study. The results of the study were as follows. 1) Through item analysis, 85.4% of the total items showed a high index of discrimination, i.e, of more than +.40, which all was significant discrimination (P<0.001) excluding two items. 2)Factor analysis, which was oriented toward combining factors proper to theory, showed that the M.S.S. consisted of 6 factors and its total variance was 50.18%. The 6 factors were marital satisfaction (factor 1), marital social psychological companionship (factor 2), obstacles to marriage (factor 3), dissatisfaction of marital relationship (factor 4), attitude of the reasonable marital relationship (factor 5), and cognition of married life (factor 6), 3) internal consistency reliability of the M.S.S. was 0.951 and the reliability of the total items after excluding two through item analysis 0.956 and 0.949 respectively, which showed a high internal consistency 4) The marital satisfaction examined by the M.S.S showed significant differences according to sex, education , income, the duration of marriage, the number of children but no significant differences according to age, and family type. From these results, it will be concluded that the M.S.S is a reliable and valid psychological scale for examining marital satisfaction of Korean couples. The limitations of this study were as follows. 1) It can not be generalized to all Korean couples because the subjects was sampled from Seoul or satellite cities. 2)The factor analysis in this study was oriented toward combining factors proper to theory. However, it was very difficult to find out the factors because the components of the M.S.S. was more or less abstract. Thus, from these results some suggestions follow for developing the marital satisfaction scale proper to Korean couples systematically and scientifically. 1) The subjects must be sampled form urban as well as rural areas 2)Factor analysis in this study is oriented toward finding out factors of the M.S.S. Thus, it is needed to analyze the factor validity or construct validity by multitrait - multimethod of the scale with more theoretical conceptualization. 3) It is necessary to examine whether marital satisfaction shows difference according to couples and psychological variables besides objective demographic variables. 4) More research is needed before the M.S.S. con be adapted into a turely useful marital satisfaction scale for Korea.

Background: The purpose of this research was to examine the fall incidence rate and its related factors of fall in inpatients. Methods: The data were collected from the 138 fall incident reports in one tertiary hospital in Seoul from April 1st 1999 to September 30th 2001. The Fall Incident Report Form was originally developed based on that of Massachusetts General Hospital revised in 1995. And this was modified for this survey by the collaborating work of QI team including researcher and department of nursing service of this particular hospital. The contents of Fall Incident Form were general characteristics of patient. factors related to fall. types and places of fall. circumstances, nursing interventions. and outcome. Results: 1) The incidence rate of fall was 0.08% of total discharged patients and 0.081 per 1000 patient-day. This incidence rate is much lower than that of several hospitals in USA. This finding might result from the different incidence report system of each hospital. 2) The characteristics of fall-prone patient were found as follows. They were mostly over 60 years old, in alert mental status, ambulatory with some assistance, and dependent on ambulatory device. The types of diseases related high incidence rate were cerebrovascular disease(3.2), hypertension(1.6), cardiovascular disease(1.4), diabetes(1.3) and liver disease(0.6). 3) The majority of fall events usually occurred m bed. bedside(walking or standing) and bathroom in patient room. Usually they were up on their own when they fell. And there were more falls of elderly occurred during night time than day or evening. 4) 63.8% of fall events resulted in physical injuries such as fracture and usually the patients had diagnostic procedures and some treatment(ex. suture) which caused additional cost to the patients and their families. 5) The found risk factors of fall were drugs(antihypertensive drug, diuretics) and environmental factors like too high bed height, long distance of bedside table and lamp switch, and slippery tile of bathroom floor. Conclusion: Considering these results, every medical and nursing staff should be aware of the risk factors of patients in hospital, and should intervene more actively the preventive managements, specially for the elderly patients during night. Therefore, it is recommended that the development of Fall Prevention Programs based on these results.
