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.

This article is aimed at understanding the political narratives represented in the National Museum of Indonesia. Starting initially as a colonial museum, the National Museum of Indonesia functioned as a useful tool for the Dutch colonial force to fuel its imaginations of the colonial territory and the people within it. The Dutch used the cultural display to advertize its benevolent colonial rule. All the while, the museum also inevitably reflected orientalism on the people and the culture of the colony. The republic of Indonesia inherited the colonial museum's practices and its display patterns. The business surrounding the museum also played a key role in the newly-born nation-state laying out a future for its redefined territory and people. Thus, what the colonial force imagined for the colonial territory through the study of museum displays was rather directly transferred to the republic without serious consideration of the decolonization process. Four main characteristics have been seen in the museum displays. The first is an emphasis on the glorious Hindu-Buddha history, from which numerous temples, statues, and jewelry have been found. Secondly, the Islamic period, which spanned between the Hindu-Buddha times to the colonial era, has almost completely been eliminated from the display. Third, the colonial era has been depicted as the time of Europe's exportation of scientific tools and adaption of sophisticated living patterns. Fourth, the images of ethnic groups were represented as being stagnant without reflecting any challenges and responses that these groups had faced throughout history. Looking at these display patterns, it can be concluded that all the dynamic internal developments and anti-colonial resistance that took place during the Islamic and Colonial Era have simply not been represented in the museum display. These display patterns do not reflect the real history or culture of the archipelago. Two considerations are thought to have influenced the neglecting of social realities in the display. The first of which is the Dutch's and Republic's apprehension over the possible political upheaval by the Islamic forces. Yet, more fundamentally, cultural displays themselves are distinct from historical education in that the former pays more attention to business ideas with an aim to attract tourists rather than to project objective historical knowledge. Thus, in cultural displays, objects which work to stimulate fantasies and spur curiosity on archipelagic culture tend to be selected and emphasized. In this process, historical objectivity is sometimes considered less vital. Cultural displays are set up to create more appealing narratives for viewers. Therefore, if a narrative loses its luster, it will be replaced by another flashy and newly-resurrected memory. This fact reveals that museums, as transmitters of historical knowledge, have a certain degree of limitation in playing their role.

본 연구는 코헛의 이론을 중심으로 병리적 나르시시즘에 대한 상담자의 자기대상 역할 연구를 하였다. 이론적 이해에서는 나르시시즘과 병리, 자기대상을 논하였다. 나르시시즘과 병리는 응집된 자기의 형성에 실패라 할 수 있다. 초기 유아의 자아는 양육자로부터 적절한 공감과 사랑을 받을 때 통합된 응집적 자기를 형성할 수 있다. 환언하면 자기애적 성격은 취약한 환경에서 공감과 수용을 받지 못하여 무력하고 취약한 자기 또는 분노로 가득 차 있다. 그리고 자기애적 사람들은 세상을 두려워하고 자신의 무력하고 공허한 자기감으로부터 자신을 보호하기 위해 거대자기 환상을 유지한다. 한편으로 자기대상이 제공하는 수용과 경탄의 반응을 경험할 때 과대적 자기는 강화되고 창조성을 발휘할 수 있다. 유아는 자기대상과의 관계 경험이 손상이 될 경우에 자기는 파편화된 자기(fragmented self)로 남게 된다. 따라서 결과에 따른 결론은 다음과 같다. 병리적인 나르시시즘에 대한 상담자의 자기대상 역할은 공감적 자기대상이 되어 내담자로 하여금 건강한 응집적 자기를 형성하도록 하여야 한다. 또한 자기대상이 유아의 욕구에 자상하게 안내하며 이상적 모델로 역할을 할 때 유아는 건강한 이상을 추구하며 초기의 자기애적 평형상태를 유지할 수 있다.

Korean agriculture has encountered two problems. One is internal income disparity between rural and urbarn area and the other is external Uruguay Round trade problems as an abolition of direct and indirect import barriers, reduction in export subsidies and to reduce internal price supports. These problems will be brought severe farm problems such as decreasing farm household income and repressing agricultural growth in the near future. Considering the above inevitable facts Korean government has implemented several development projects such as rural industrial area development project, rural special production area development project, leisuresight seeing farm development project, traditional food development project, unskilled labor training project for off-farm employment and so on, to increase farm household income through off-farm income increase. This study was mainly concentrated on the identification of operational problems and post evaluation of the rural special production area development projects which aimed at increasing non-farm incomes and giving employment opportunity for rural farmers in small factories processing regional special farm products and mine products. The main findings and problems to be solved for the successful project implementation are as followed ; 1. Total number of the special production area development projects as of the end of 1991 was amount to 138, and total number of farm household participated were estimated at 2,079, and total amount of off-farm income per farm household was reached to 3,011 thousand won. 2. The total number of processed special products have increased from 21 items in 1981 to 56 items in 1991. On the other hand the total number of farm household participated in the projects have decreased from 2,518 to 2,079 during same period. 3. Total amount of investment for the projects has increased from 1,429 million won in 1981 to 24,760 million won in 1991 but the rate of G'T loan of the total investment has reduced from 24.5% to 5.2% during same period. 4. 138 special production area development project are classified into 6 kinds of commodity groups such as 19 of general industrial good production areas, 52 of folks-industrial art objects production areas, 39 of food processing areas, 9 of fiber and texstile processing areas, 18 of agricultural and fishery inputs processing areas and 1 of stone processing area. 5. The total production value in 1990 was estimated 20,169 million won of which export was amount to 2,627 million won. 6. The finacial rate of return of the UNGOK KUGIJA Tea processing Project operated by UNGOK coops and BAKSAN ginseng tea processing project were estimated at 45.4% (B/C Ratio=1.17, NPV=152.5 million won) and 17.7% (B/C Ratio=1.12, NPV=120.2 million won) respectively. 7. More favorite terms and condition of the loan including collateral problems have to be given to farmers participated. Heavy investment and G'T subsidy policies should be started for the successful project implementation anf farm household income increase. 8. To expand market demand of the rural special goods G'T have to provide special program of TV or other mass media for commodity propaganda and the total cost concerned must be supported by G'T subsidy. 9. The special farm products as GUGUJA,MOSI'Ramie', Ginseng. SOGOKJU,HEMP,Mushroom.DUGYUNJU and Chesnut processing projects have to be propelled and expanded for off-farm income increase in Chung Nam Province. 10. Direct operational pattern of the special production area by coops is more favorable to farmers and recommendable considering with off-farm income increase and market demand creation throughout Korea. 11. In rural area, special organizations for project appraisal are not exist. Accordingly special training program, project appraisal, formulation and preparation for civil servants concerned have to be prepared for project selection and sound implementation under limited budget and financial support.

주인공의 모험을 조력하는 감초역할로 등장했지만 머천다이징 시장에서 크게 성공한 애니메이션캐릭터 올라프(겨울왕국), 미니언즈(슈퍼배드) 등등의 대중적인 인기비결은 귀여운 디자인에 있기도 하지만 해당 캐릭터의 심층에 이행대상의 특성들이 내포되어 있기 때문이라고 추정할 수 있다. 이행대상(transitional object)이란 아동심리학자 도널드 위니콧이 제안한 개념으로 간단히 표현하자면 유아가 어머니에게서 정신적으로 분리되는 과정에서 일시적으로 어머니를 대신하는 애착인형이나 상상 친구를 말한다. 하지만 이행대상 이론을 서사콘텐츠캐릭터연구에 적용하기 위해서는 이행대상 캐릭터에 관한 기준과 지표를 새롭게 정립하는 연구가 선결 되어야 했다. 이에 본 연구는 성장주체와 성장조력자의 '정서적 관계'를 기준으로 이행대상 캐릭터의 성향을 판단하는 정서적 지표를 새롭게 구축하였다. 그 지표는 4가지 정서적 역할(유사가족, 성장매개, 전기이행대상, 후기이행대상), 6가지 정서적 행위(안아주기, 보호하기, 받아주기, 주도권제공, 관계개선, 상호주관), 3가지 정서적 인상(접촉인상, 보호제공인상, 보호유도인상, 공격수용인상)항목으로 구성되었다. 위 지표를 적용하여 가족용 장편애니메이션<인사이드아웃(Inside out)>의 주요캐릭터들을 분석해 보았을 때 빙봉(Bing Bong)과 슬픔이(Sadness)가 높은 이행대상 캐릭터 성향을 보였다. 특히 슬픔이의 분석을 통해 가족용 장편애니메이션의 이행대상 캐릭터들이 어떠한 양상으로 작품의 성장서사를 강화하는데 활용되는지 유추 할 수 있었다. 이행대상 캐릭터인 슬픔이는 성장주체에게 '촉진적 정서'를 제공하는 양상으로 성장주체가 외적인 성공을 거둘 수 있도록 돕고 성장주체의 내적인 성숙과제를 '투사' 하는 양상으로 성장주체의 내적성숙을 도와 성장서사를 안팎으로 보조하고 있었던 것이다. 연구결과 이행대상 캐릭터들이 성장주체에게 제공하는 정서적 체험은 성장주체에게 감정이입하는 관객들에게도 전이되어 가족용 장편애니메이션의 어린이관객과 어른관객들에게 각각 다른 층위의 정서적인 만족감을 안겨주고 있었다.

To survive in the global competitive environment, enterprise should be able to solve various problems and find the optimal solution effectively. The big-data is being perceived as a tool for solving enterprise problems effectively and improve competitiveness with its' various problem solving and advanced predictive capabilities. Due to its remarkable performance, the implementation of big data systems has been increased through many enterprises around the world. Currently the big-data is called the 'crude oil' of the 21st century and is expected to provide competitive superiority. The reason why the big data is in the limelight is because while the conventional IT technology has been falling behind much in its possibility level, the big data has gone beyond the technological possibility and has the advantage of being utilized to create new values such as business optimization and new business creation through analysis of big data. Since the big data has been introduced too hastily without considering the strategic value deduction and achievement obtained through the big data, however, there are difficulties in the strategic value deduction and data utilization that can be gained through big data. According to the survey result of 1,800 IT professionals from 18 countries world wide, the percentage of the corporation where the big data is being utilized well was only 28%, and many of them responded that they are having difficulties in strategic value deduction and operation through big data. The strategic value should be deducted and environment phases like corporate internal and external related regulations and systems should be considered in order to introduce big data, but these factors were not well being reflected. The cause of the failure turned out to be that the big data was introduced by way of the IT trend and surrounding environment, but it was introduced hastily in the situation where the introduction condition was not well arranged. The strategic value which can be obtained through big data should be clearly comprehended and systematic environment analysis is very important about applicability in order to introduce successful big data, but since the corporations are considering only partial achievements and technological phases that can be obtained through big data, the successful introduction is not being made. Previous study shows that most of big data researches are focused on big data concept, cases, and practical suggestions without empirical study. The purpose of this study is provide the theoretically and practically useful implementation framework and strategies of big data systems with conducting comprehensive literature review, finding influencing factors for successful big data systems implementation, and analysing empirical models. To do this, the elements which can affect the introduction intention of big data were deducted by reviewing the information system's successful factors, strategic value perception factors, considering factors for the information system introduction environment and big data related literature in order to comprehend the effect factors when the corporations introduce big data and structured questionnaire was developed. After that, the questionnaire and the statistical analysis were performed with the people in charge of the big data inside the corporations as objects. According to the statistical analysis, it was shown that the strategic value perception factor and the inside-industry environmental factors affected positively the introduction intention of big data. The theoretical, practical and political implications deducted from the study result is as follows. The frist theoretical implication is that this study has proposed theoretically effect factors which affect the introduction intention of big data by reviewing the strategic value perception and environmental factors and big data related precedent studies and proposed the variables and measurement items which were analyzed empirically and verified. This study has meaning in that it has measured the influence of each variable on the introduction intention by verifying the relationship between the independent variables and the dependent variables through structural equation model. Second, this study has defined the independent variable(strategic value perception, environment), dependent variable(introduction intention) and regulatory variable(type of business and corporate size) about big data introduction intention and has arranged theoretical base in studying big data related field empirically afterwards by developing measurement items which has obtained credibility and validity. Third, by verifying the strategic value perception factors and the significance about environmental factors proposed in the conventional precedent studies, this study will be able to give aid to the afterwards empirical study about effect factors on big data introduction. The operational implications are as follows. First, this study has arranged the empirical study base about big data field by investigating the cause and effect relationship about the influence of the strategic value perception factor and environmental factor on the introduction intention and proposing the measurement items which has obtained the justice, credibility and validity etc. Second, this study has proposed the study result that the strategic value perception factor affects positively the big data introduction intention and it has meaning in that the importance of the strategic value perception has been presented. Third, the study has proposed that the corporation which introduces big data should consider the big data introduction through precise analysis about industry's internal environment. Fourth, this study has proposed the point that the size and type of business of the corresponding corporation should be considered in introducing the big data by presenting the difference of the effect factors of big data introduction depending on the size and type of business of the corporation. The political implications are as follows. First, variety of utilization of big data is needed. The strategic value that big data has can be accessed in various ways in the product, service field, productivity field, decision making field etc and can be utilized in all the business fields based on that, but the parts that main domestic corporations are considering are limited to some parts of the products and service fields. Accordingly, in introducing big data, reviewing the phase about utilization in detail and design the big data system in a form which can maximize the utilization rate will be necessary. Second, the study is proposing the burden of the cost of the system introduction, difficulty in utilization in the system and lack of credibility in the supply corporations etc in the big data introduction phase by corporations. Since the world IT corporations are predominating the big data market, the big data introduction of domestic corporations can not but to be dependent on the foreign corporations. When considering that fact, that our country does not have global IT corporations even though it is world powerful IT country, the big data can be thought to be the chance to rear world level corporations. Accordingly, the government shall need to rear star corporations through active political support. Third, the corporations' internal and external professional manpower for the big data introduction and operation lacks. Big data is a system where how valuable data can be deducted utilizing data is more important than the system construction itself. For this, talent who are equipped with academic knowledge and experience in various fields like IT, statistics, strategy and management etc and manpower training should be implemented through systematic education for these talents. This study has arranged theoretical base for empirical studies about big data related fields by comprehending the main variables which affect the big data introduction intention and verifying them and is expected to be able to propose useful guidelines for the corporations and policy developers who are considering big data implementationby analyzing empirically that theoretical base.
