Purpose: The primary goal of wound management is to avoid infection. Wounds in all patients presenting to the Emergency Department are contaminated with bacteria. Despite this, there is a low incidence of infection. Unfortunately, physicians continue to use antimicrobial agents indiscriminately. The authors intended to determine the effect of selective antimicrobial agents and the indications for appropriate antimicrobial agent use in traumatic simple wounds. Methods: This prospective study was performed from Jul. 2005 to Aug. 2005. A pilot study had been performed from Nov. 2003 to Jul. 2004 at the Ewha Woman's University Mokdong Hospital. Structured data sheets were completed at the times of the patient's visits to the Emergency Department and to the Outpatient Department for follow-up. Infection was determined at the time of follow-up. The indications of antimicrobial agent use are immunocompromised patients, wounds contaminated for 3 hours or longer, devitalized tissue, and extremity wounds except hand wounds caused by sharp objects. Results: The study enrolled 216 injured patients. The general characteristics of patients and wounds between the two groups were not significantly different. The antimicrobial agent use and infection rate of the pilot study were 227 cases (90.4%) and 10 cases (4.0%), and those of this study were 100 cases (46.3%) and 9 cases (4.1%). In this study, antibiotic use was reduced to almost half compared with the previous study, but the infection rate was similar (p<0.001). Conclusion: Rational use of antimicrobial agents in simple wounds reduced the use of antimicrobial agents in the Emergency Department without increasing the infection rate.

With the advent of age that people spend more time and money on leisure activities, there is increasing interest in professional sport games. The location of large scale sport facilities has substantial impacts on existing transportation pattern because the facility attracts and generates massive traffic volume within a short period of time. This study aims to develop a mode choice model of leisure trips of which the destinations are a sport facility. A structured SP (stated preference) survey questionnaires were developed through an experimental design, and professional sport spectators were asked to state their preference in the choice of transport mode to the sport facility. The survey results show that public transportation is preferred to passenger cars for their trip to big sports event, implying that the convenience of back home trip after the event is an important factor of their mode choice. This study is a rare research on the trip pattern to sports complex in Korea, which provides policy implications on the provision of mass transit including subway system to large scale sport complexes. And it is also expected that this study contributes to future researches on leisure trip pattern.

As recently the interest in the future industry grows high, the demand for forecasting the future shape of science and technology, especially exploring 'weak signals' of changes in science and technology, increases as well. The 'weak signals' means that currently they are uncertain and abnormal signals, but are preliminary signals which might lead future changes. Accordingly they can provide important clues to the future forecast. The study of 'weak signals' has its significance in providing important clues to the projection of the future technology earlier. As it has not a long history from its concept to exploration methods to utilization, more intensive study is required. Exploring 'weak signals' has been conducted mainly through the information analysis by experts with a high level of intelligence and sense. However, such an analysis is difficult and broad in scope, and furthermore the interpretation of analysis results is very limited, relying primarily on the decision of experts themselves. The purpose of this study is to provide a more objectified way to support these expert-based tasks. It derives quantitative results from non-structured article information and provides a logical basis for detecting the signals based on the results.

Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to achive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers 'Motive-Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive(55.1%-28.2%) and action(38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher artier level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment(salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

Objectives : The aim of this study is to identify factors determining the purchase of private health insurance under the mandatory National Health Insurance(NHI) system in Korea. Methods : The data were collected by the National Cancer Center in Korea. It includes cancer patients who were newly diagnosed with stomach (ICD code, C16), lung(C33-C34), liver (C22), colorectal cancer(C18-C20) or breast(C50) cancer. Data were gathered from the hospital Order Communication System (OCS), medical records, and face-to-face interviews, using a structured questionnaire. Clinical, socio-demographic and private health insurance related factors were also gathered. Results : Overall, 43.9% of patients had purchased one or more private health insurance schemes related to cancer, with an average monthly premium of \65,311 and an average benefit amount of \19million. Females, younger aged, high income earners, national health insurers and metropolitan citizens were more likely to purchase private health insurance than their counterparts. Conclusions : About half of Korean people have supple-mentary private health insurance and their benefits are sufficient to cover the out-of-pocket fees required for cancer treatment, but inequality remains in the purchase of private health insurance. Further studies are needed to investigate the impacts of private health insurance on NHI, and the relationship between cancer patients' burden and benefits.

Objectives : In this study, we conducted a focus group interview among expatriates living in Korea, to investigate their experiences and perceptions of acupuncture and Korean Medicine in order to improve the usage of Korean Medicine in the medical tourism market. Methods : The inclusion criteria for the focus group interview was: (1) participants between the age of 20 to 75 years old; (2) those who had lived in Korea for more than 90 days, and (3) those who were able to express their thoughts freely in English. The participants were informed that the interviews will be recorded and transcribed. We ended recruitment once saturation of materials was met. Semi-structured interviews were conducted, and the data was analyzed after each interview. Results : The interviews were held between June to December 2016. Twenty-four participants were recruited but four dropped out and a total of twenty participants successfully finished the interviews. Six focus group interviews were conducted. Analysis revealed that Korean Medicine was relatively less known compared to Traditional Chinese Medicine or Complementary and Alternative Medicine. Participants automatically associated acupuncture with the management of pain or stress and replied that these were the areas that they thought acupuncture would be most effective. Positive experiences with acupuncture and with the acupuncture practitioners were factors that promoted the use of acupuncture whereas lack of awareness, accessibility and accreditation were factors that hindered its use. Other factors that hindered the use of acupuncture was needle phobia and the perception that acupuncture lacks scientific evidence. Conclusions : Awareness on Korean Medicine and acupuncture is low. Participants lack awareness on what diseases acupuncture can treat, the scientific evidence behind the mechanism of action, and the rigorous education system that Korean Medicine doctors must go through to get their license. Rigorous marketing should be encouraged, which includes greater exposure in the media, more honest reviews from patients, and promotion of the scientific evidence base.

Mathematically gifted children have creative curiosity about novel tasks deriving from their natural mathematical talents, aptitudes, intellectual abilities and creativities. More effect in nurturing the creative thinking found in brilliant children, letting them approach problem solving in various ways and make strategic attempts is needed. Given this perspective, it is desirable to select open-ended and atypical problems as a task for educational program for gifted children. In this paper, various types of open-ended problems were framed and based on these, teaming activities were adapted into gifted children's class. Then in the problem solving process, the characteristic of bright children's mathematical thinking ability and examples of problem solving strategies were analyzed so that suggestions about classes for bright children utilizing open-ended tasks at elementary schools could be achieved. For this, an open-ended task made of 24 inquiries was structured, the teaching procedure was made of three steps properly transforming Renzulli's Enrichment Triad Model, and 24 periods of classes were progressed according to the teaching plan. One period of class for each subcategories of mathematical thinking ability; ability of intuitional insight, systematizing information, space formation/visualization, mathematical abstraction, mathematical reasoning, and reflective thinking were chosen and analyzed regarding teaching, teaming process and products. Problem solving examples that could be anticipated through teaching and teaming process and products analysis, and creative problem solving examples were suggested, and suggestions about teaching bright children using open-ended tasks were deduced based on the analysis of the characteristic of tasks, role of the teacher, impartiality and probability of approaching through reflecting the classes. Through the case study of a mathematics class for bright children making use of open-ended tasks proved to satisfy the curiosity of the students, and was proved to be effective for providing and forming a habit of various mathematical thinking experiences by establishing atypical mathematical problem solving strategies. This study is meaningful in that it provided mathematically gifted children's problem solving procedures about open-ended problems and it made an attempt at concrete and practical case study about classes fur gifted children while most of studies on education for gifted children in this country focus on the studies on basic theories or quantitative studies.

The current business environment has been characterized as less munificent, highly uncertain and constantly evolving. In this environment, the company with dynamic capability is reported to be more successful than others in building competitive advantage. Dynamic capability focuses on the link between a dynamically changing environment, strategic agility, architectural reconfiguration, and value creation. Being characterized to be flexible and adaptive to market circumstance changes, an organization with dynamic capability is described to have high resource fluidity, which represents business process, resource allocation, human resource management and incentives that make business transformation faster and easier. Successful redeployment of the resources for dynamic adaptation requires organizational forms and reward systems to be well aligned with firm's technological infrastructures and business process. The alignment is considered to be an executive level commitment. Building dynamic capability is knowledge driven; relying on new knowledge to reconfigure firm's resources. Past studies established the link between the effective execution of a knowledge-focused strategy and relevant setting of architectural elements such as human resources, structure, process and information systems. They do not, however, describe in detail the underlying processes by which architectural elements are adjusted in coordinated manners to build knowledge-driven dynamic capability. In fact, understandings of these processes are one of the top issues in IT management. This study analyzed how a Korean corporation with a knowledge-focused strategy aligned its architectural elements to develop the dynamic capability and thus create value in the dynamically changing markets. When the Korean economy was in crisis, the company implemented a knowledge-focused strategy, restructured the organization's architecture by which human and knowledge resources are identified, structured, integrated and coordinated to identify and seize market opportunity. Specifically, the following architectural elements were reconfigured: human resource, decision rights, reward and evaluation systems, process, and IT infrastructure. As indicated by sales growth, the reconfiguration helped the company create value under an extremely turbulent environment. According to Ancona et al. (2001), depending on the types of lenses the organization uses, different types of architecture will emerge. For example, if an organization uses political lenses focusing on power, influence, and conflict. the architecture that leverage power and negotiate across multiple interest groups would emerge. Similarly, if an organization uses economic lenses focusing on the rational behavior of organizational actors making choices based on the costs and benefits of action, organizational architecture should be designed to motivate and provide incentives for the actors (Smith, 2001). Compared to this view, information processing perspectives consider architecture to be designed to maximize the capacity of information processing by the actors. Using knowledge lenses, the company studied in this research established architectural elements in a manner that allows the firm to effectively structure knowledge resources to form dynamic capability. This study is revelatory single case with a historic perspective. As a result of this study, a set of propositions and a framework are derived, which can be used for architectural alignment.

Zooplankton were sampled horizontally with a standard net from the surface layer of the estuarine system of Mankyong River and Dongjin River in October, 1989, March, May, and July, 1990. Among dominant taxa of the zooplankton community, copepods were predominant in October, 1989 and March, 1990 and Noctiluca scintillans in May and July, 1990. Abundance of zooplankton showed considerable spatial and temporal fluctuations with a range of $12~9,256ind./m^3$ in wet weight. In the copepod community, Pseudodiaptomus inopinus and Paracalanus inducus were predominant in October, 1989: Acartia hudosonica and P. inducus in March, 1990; A. hudosonica and Centropages abdoinalis in May, 1990; A. pacifica, P. indicus and Tortanus spinicaudatus in July. 1990. In summer (July),there were large seasonal changes in salinity ($0.7~28.9\textperthousand$), due to monsoonal flooding, and associated changes in community structured of copepods. There were eight species of copepods in the mixo-mesohaline zone ($5.0~28.8\textperthousand$), namely Acartia pacifica, A. hudosonica, Centropages tenuiremis, C. abdominalis, Labidocera Euchaeta, Tortanus spinicaudatus, corycaeus affinis and Paracalanus indicus. On the other hand, Thermocouple hyalinus, Pseudodiaptomus inopinus and Sinocalanus tenellus occurred in the mixo-oligohaline zone ($0.5~5.0\textperthousand$), showing more tolerant of low salinity than any of the other species. In the mixoeuhaline zone ($>28.0\textperthousand$), Labidocera bipinnata, Oithona similes, Calanus sinicus, Acartia omorii and Tortanus forcipatus were founded.

HTML5 has developed not to have browser dependancy considering interoperability as same as maintaining compatability with lower versions of HTML. HTML5, the newest web standardization is on going of being structured. Along with the smart phone boom, HTML5 is spotlighted because it can be applied to cross platforms in mobile web environments. Specially the local Storage that has been listed in new features in HTML5 supports offline function for web application that enables web application to be run even when the mobile is not connected to 3G or wifi. With Local storage, development of server-independent web application can be possible. However Local storage stores plaintext data in it without applying any security measure and this makes the plaintext data dangerous to security threats that are already exist in other client side storages like Cookie. In the paper we propose secure Local storage methods to offer a safe way to store and retrieve data in Local storage guaranteeing its performance. Suggested functions in this paper follow localStorage standard API and use a module that provide cryptographic function. We also prove the efficiency of suggested secure Local storage based on its performance evaluation with implementation.
