The aim of this paper is to propose an integrative definition of key account management (KAM) at the organizational level through a content analysis of the existing definitions of KAM available in the business literatures. A representative pool of definitions of key account management was generated through literature review from twenty three journals that covers the divergence of name variety like global account management, strategic account management, national account management, international key account management, key client management, major account management, key customers management and key account management. Relating to the definition of key account management various attributes are identified through content analysis and according to the relevance, profile for each attributes are developed. On the basis of these attributes a diagrammatic and textual definition is proposed that covers the different standpoints and aspects of key account management approach and captures its essence as well. Eventually, several strategic implications are derived that create the field for further empirical investigation.

Many improper development action were performed at subsurface environment, because there were not any definition about subsurface environment in Korea. The purpose of this study was to establich a definition on subsurface environment. Subsurface environment could be divided by subsurface natural environment and subsurface living environment. The soil, groundwater, ecosystems, landscapes, underground space (naturally occurred) were included in subsurface natural environment. And space and facilities used by human were classified as subsurface living environment.

Most of calculus and real analysis are concerned with the study on continuous functions. Because of self-sustaining concept caused by everyday language, continuity has difficulties. This kind of viewpoint is strengthened with that teacher explains continuity by graph drawn ceaselessly and so finally confused with mathematics concept which is continuity and connection. Thus such a concept image of continuity becomes to include components which create conflicts. Therefore, we try to analyze understanding of continuity on university students by using the concept image as an analytic tool. We survey centering on problems which create conflicts with concept definition and image. And we investigate that difference of definition in continuous function which handles in calculus and analysis exists and so try to present various results on university students' understanding of continuity concept.

This study is on a Boolean B or Boolean lattice L in abstract algebra with closed binary operation *, complement and distributive properties. Both Binary operations and logic properties dominate this set. A lattice sheds light on binary operations and other algebraic structures. In particular, the construction of the elements of this L set from idempotent elements, our definition of k-order idempotent has led to the expanded definition of the definition of the lattice theory. In addition, a lattice offers clever solutions to vital problems in life with the concept of logic. The restriction on a lattice is clearly also limit such applications. The flexibility of logical theories adds even more vitality to practices. This is the main theme of the study. Therefore, the properties of the set elements resulting from the binary operation force the logic theory. According to the new definition given, some properties, lemmas and theorems of the lattice theory are examined. Examples of different situations are given.

In this study, entropy definition and explanation in twelve general chemistry textbooks published in USA including what Korean universities select are analyzed. Analysis consists of two parts. One is diachronic analysis which focuses on the change between editions of same authors and the other is contents analysis composed of three sections‐ disorder in entropy definition and explanation, microstates number in entropy definition and explanation, possibility of alternative conception in learning statistical entropy and thermal entropy. As a result, the definition that entropy is the measure of disorder is denied and explanation using microstates number is introduced. Also, caution for the possibility of alternative conception that there are two different entropies is found. Reflecting the change in entropy explanation on new chemistry curriculum and reeducating teachers are meaningful on improvement of Korean chemistry education.

Background : Clinical practice guidelines are an increasingly familiar part of clinical practice. Moreover, rigorously developed evidence based guidelines has been widely used. However, in Korea, some of published documents as clinical practice guidelines have shown considerable disparity in structure, contents and quality. This is mainly because there is no consensus on the definition and quality standard of clinical practice guidelines. The purpose of this study was to draw consensus on the definition and the quality standard about clinical practice guidelines. Method : We developed a questionnaire about the definition of clinical practice guidelines with inclusion criteria(23 items) and the quality standard(30 items). We selected 9 experts who had prior experience in developing and implementing guidelines. Rating methods for appropriateness of items were adopted from the RAND method. Consensus was drawn in three rounds. Results : Of the 47 items agreed, 40 items were determined to be appropriate. Clinical practice guidelines were defined as "scientifically and systematically developed statements to assist practitioners and patients on making decisions about appropriate health care for specific clinical circumstances." Narrative reviews, systematic reviews or health technology assessment without recommendations, translation of foreign guidelines, guidelines for patients only and training manuals were not considered as clinical practice guidelines. For the quality standard of clinical practice guidelines, 27 items were deemed necessary. Conclusions : The consensus on the definition with inclusion criteria and the quality standard of clinical practice guidelines carries an important meaning as the first attempt to draw a general agreement in our society. The unique achievement of the consensus reflects the current status of clinical practice guidelines that there has been a high tendency to adapt foreign guidelines. We hope efforts of this kind will continue to bring improvement in clinical practice guidelines.

Background: There is no consensus on the definition of primary care in South Korea. This study's objective was to define the concept of primary care using a Delphi method. Methods: Three expert panels were formed, consisting of 16 primary care policy researchers, 45 stakeholders, and 16 primary care physicians. Three rounds of voting, using 9-point appropriateness scales, were conducted. The first round involved rating the appropriateness of 20 previously established attributes of primary care. In the second round, panelists received a summary of the first-round results and were asked to once again vote on the 10 undetermined attributes and the provisional definition. The final round involved voting on the appropriateness of the revised definition. The Korean Language Society reviewed the revised definition. Results: Four core (first-contact care, comprehensiveness, coordination, and longitudinality) and three ancillary (personalized care, family and community context, and community base) attributes were selected. The Korean definition of primary care was accomplished with all three panel groups arriving at a 'very good' level of consensus. Conclusion: The Korean definition of primary care will provide a framework for evaluating performance of primary care in South Korea. It will also contribute to resolving confusion about the concept of primary care.

In this study we aimed to find out pesticide types with probability for underestimation of dietary exposure to pesticide residues in Korea by comparing the residue definitions between Korea and Codex standards. In addition, we sought to establish priorities regarding the necessity of review concerning pesticide types and their impacts based on the risk assessment and dietary exposure underestimation. As a result, we found that according to the residue definition information, 44 pesticides have probability for underestimation in terms of dietary exposure assessments. Among them, 24 pesticides have priority for review of dietary exposure underestimation and its impacts on risk assessment, based on the ADI values of pesticides, Korean MRL information and toxicological information of metabolite. The 24 pesticides were as follows: acibensolar-S-methyl, chlorfenapyr, chlorothalonil, cyantraniliprole, cyclaniliprole, cyflumetofen, dithiocarbamates, fenamidone, fenpyroximate, fluazifop-P-butyl, fluopicolide, flupyradifuron, fluxapyroxad, glyphosate, hexythiazox, isoprothiolane, isopyrazam, myclobutanil, penthiopyrad, propiconazole, spinetoram, spiromesifen, spirotetramat, trifloxystrobin. Furthermore, chlorfenapyr, chlorothalonil, dithiocarbamates and fenamidone may have considered a top priority for review due to greater toxicity of metabolite. This study could be of great use for improvement on risk assessment approaches in South Korea regarding pesticide residues in food commodities.

In a recent year, the broadcasting system has been changed from analogue to digital all over the world, not just in Korea, and Korea aims at accomplishing 100% digital broadcasting by 2013. The HD(High Definition) Video Format, which currently plays a key role in digital broadcasting system, has been gradually extended in the field of broadcasting and movie. Additionally, many kinds of camcoders and editing systems have been rapidly converted into the digital types, and they are supporting to photograph and video editing systems with the various types of image formats such as SD(Standard Definition) format, HD format, 2K, 4K, etc. Tape Video Storage System, which has been usually used in the stage of photographing by this day, is gradually evolving into Tapeless Video Data Storage System. Thus in this study, Video Compression method of HD format photographed by Sony PMW-EX3, one of major tapeless camcoders, is studied and also the way of applying it effectively in Avid Media Composer, a non-linear editing system, is discussed.
