  • 노트북 컴퓨터, 스마트폰 및 기타 단말기 등 네트워크를 제공하는 모바일 기기가 증가함에 따라 무선 인터넷에 대한 많은 기술들이 발전하고 있다. IEEE 802.11은 흔히 무선랜, 와이파이라고 부르는 좁은 지역을 위한 컴퓨터 무선 네트워크에 사용되는 기술로 일상생활에서 쉽게 접할 수 있으며 액세스 포인트(AP)와 네트워킹이 가능하지만 무선랜은 보안에 취약하고 제 3자가 AP에 불법으로 접속하여 패킷을 조작하거나 정보를 빼낼 가능성이 있어 주의가 필요하다. AP (Access Point)는 무선 환경을 제공하는 기기로써 카페와 같은 공공장소에 설치되고 있다. AP는 무선인터넷을 더 편리하게 사용할 수 있게 한다. 하지만 IEEE 802.11 가진 많은 취약점 때문에 공격자는 AP와의 통신을 쉽게 도청할 수 있다. 따라서 본 논문에서는 무선랜 환경에서 패킷 분석을 위한 모니터링 시스템을 설계하고 구현한 것으로서 최근 스마트폰의 보급 확대에 따른 모바일상의 보안문제가 크게 대두되고 있는 시점에서 주변에 어떤 AP와 스테이션이 통신을 하며, AP의 정보를 캡처하여 보안상의 취약점을 알아내고 분석할 수 있는 무선 네트워크 패킷을 분석을 위한 모니터링 시스템을 개발하고자 하였다.

  • The purpose of this study is to find out problems in obesity management through survey and analysis of the actual conditions from the view of a elementary schools school-nurses and to establish fundamental data for efficient obesity management. The subjects for this study were 313 numbers of elementary school-nurses in Kyung-Sang-Pook-Do. The data were collected through mail questionaries from November 1 to November 30, 1997. The major findings in this survey were as follows: 49.8% of the school-nurses who responded in the survey were in their 30s. The average career was 7.3years. The average service duration in their present school was 2.3 years, 55.6% of them were serving at schools which have less than ten classes total 77.2% of them were serving rural areas, 79.6% of them were serving at schools with fewer than 100 obese students. The total obesity prevalence rate was 11.4%, 13.3% were girls, 9.3% were boys. The measurement of height and weight is performed once a year for all surveyed students (91.7%), but obese students were measured as much five times (51.1%). The rate of obesity management planning was 74.1%, however the rates of evaluation and role assignment were 41. 2%, and 24.3%. 79.6% of the surveyed schools have health education classes for obesity, the rate compared (8.0 periods per year) to the whole of health education (79.1 periods per year) is 10.1%. 99.9% of the schools had counseling rooms for obesity (combined with nursing rooms) but they were used. The roote of individual counseling was 84.3%. The frequency counseling was six times a year for about 15 minutes. Obesity counseling records were kept 93.6% of the time and individual information cards were kept 98.7% of the time. The frequency of parents counseling was 42.8% and the survey shows that the main problem here was insufficient counseling facilities. The frequency of dietary guidance and exercise therapy was 84.3% and the dietary instructor was usually the school nurse at 51.7%. The frequency of obesity student exercise was 1-2 times a week and more-than-10-minutes at a time. They skip rope during the morning self-study class. The number on problem of exercise guidance at 56.2% was students' non-cooperativeness. School-nurses, 87.9%, answered that obesity management at school is necessary and 86.9% mentioned the shortage of obesity related information in present physical exercise books. From the plural responses of executing the obesity management, there are many similar problems: lack of knowledge and non-cooperation in parents at 41.9%, is predominant followed by of knowledge and non-cooperation in the children. The third problem is the lack of funds and facilities.

  • 2008년 이후 정부의 공영방송 사장 임명과 정부 비판 보도의 제한, 시사 프로그램의 폐지 압력, 그리고 재벌과 보수언론의 방송진출을 허용한 언론법 개정 등은 언론 민주화를 위협하고 있다. 이러한 상황에서 권위주의 정부 시절 언론 민주화를 위해 노력했던 언론인의 정신과 실천을 되돌아보고 숙고해서 한국 저널리즘의 미래상을 재설계 할 필요성이 있다. 송건호는 정부의 언론 장악 시도에 정면으로 맞서 보도통제를 반대하고, 국민을 위한 언론의 역할에 대해 진지한 성찰과 고민을 계속한 점에서 오늘날의 언론인이 언론 민주화의 위기를 극복할 수 있도록 현실적인 언론사상을 제시해 준다. 송건호의 언론사상을 살펴보기 위해 문헌연구 및 관련 언론인과의 인터뷰를 진행했다. 송건호의 언론사상은 민족언론, 민주언론, 독립언론 등으로 요약됐다. 첫째, 민족언론은 분단된 남북관계와 주변 강대국의 영향이 지속되는 상황 속에서 언론이 민족의 자긍심을 세우고 통일의 책무를 강조하며, 우리나라와 세계 역사에 대한 지식과 통찰력을 가져야 함을 의미한다. 둘째, 민주언론은 언론이 민주주의 사회의 기반이자 유지, 발전 양식이라는 점에서 포기할 수 없는 원칙이다. 셋째, 독립언론은 언론이 기업의 형태로 존재, 운영되는 과정에서 내외의 압력에서 자유로울 때 언론의 책무가 구현됨을 강조한다. 송건호의 언론사상은 언론 민주화의 위기를 회복하기 위한 철학과 방법론 모색의 기초 자료라는 점에서 언론학적 의미가 매우 크다.

  • 성 고정관념에서 오는 성별 불평등의 해결을 위해서는 여성과 남성 즉 젠더적 민감성과 더불어 젠더에 대한 올바른 인식이 선행되어야 한다. 이러한 점을 인지하고 개선 및 보안하고자 가정 교과에서는 교과서를 중심으로 한 양성평등에 대한 연구가 꾸준히 진행되어 왔다. 반면 2015 교육과정 개편이 새로이 있었으나 성 평등적 관점에 기초한 교과서 분석은 충분하지 못한 실정이다. 따라서 본 연구는 양성평등 관점에 기반을 두고 기술 가정 교과서를 분석하였다. 본 논문의 목적은 「기술·가정」 교과서 내 삽화가 학생들에게 균형적인 사회상을 제시한다는 교과서로서의 책임을 다 하고 있는지 알아보는 것이다. 이를 위하여 12개 출판사에서 발행한 검정교과서 「기술·가정 1」과 기술·가정 2」를 기준으로 총 24권을 분석 대상으로 선정하였고 삽화의 외형적 특징과 내용적 특징을 분석범주로 삼아 진행하였다. 연구결과를 종합해 판단해보자면 우리 교과서가 모든 면에서 성 평등적이라고 평가하기는 어려운 것으로 보인다. 부분적으로는 많은 개선이 있었지만 여전히 특정 성별에 편중되어 성 정형성이 잔재하고 있었으며 개선이 필요한 점으로 보였다. 따라서 학생들이 자발적이며 능동적인 태도를 갖추고 비판의식을 함양한다는 성 평등교육의 목적을 이루기위해서는 여성과 남성이 다양한 분야에서 서로 협력하며 활약하는 균형적인 사회상을 학생들에게 제시하는 것이 필요하다. 이를 위해 교과서 편집 시 성별의 처방적 고정관념이 존재하는 것은 아닌지 주의하고 편견 요소를 축소하여 양성평등 한 교육과정을 실현하기 위한 지속적인 점검 및 검토를 진행하는 방안이 필요함을 알 수 있다.

  • Background: Breast cancer is the most common cancer and the leading cause of cancer mortality among women of all ethnic and age groups in Malaysia. Delay in seeking help for breast cancer symptoms is preventable and by identifying possible factors for delayed diagnosis, patient prognosis and survival rates could be improved. Objectives: This narrative review aimed to understand and evaluate the level of in-depth breast cancer knowledge in terms of clinical breast examination and breast self-examination, and other important aspects such as side-effects and risk factors in Malaysian females. Since Malaysia is multicultural, this review assessed social perceptions, cultural beliefs and help-seeking behaviour in respect to breast cancer among different ethnic groups, since these may impinge on efforts to 'avoid' the disease. Materials and Methods: A comprehensive literature search of seven databases was performed from December 2015 to January 2015. Screening of relevant published journals was also undertaken to identify available information related to the knowledge, perception and help-seeking behaviour of Malaysian women in relation to breast cancer. Results: A total of 42 articles were appraised and included in this review. Generally, women in Malaysia had good awareness of breast cancer and its screening tools, particularly breast self-examination, but only superficial in-depth knowledge about the disease. Women in rural areas had lower levels of knowledge than those in urban areas. It was also shown that books, magazines, brochures and television were among the most common sources of breast cancer information. Delay in presentation was attributed mainly to a negative social perception of the disease, poverty, cultural and religion practices, and a strong influence of complementary and alternative medicine, rather than a lack of knowledge. Conclusions: This review highlighted the need for an intensive and in-depth breast cancer education campaigns using media and community health programmes, even with the existing good awareness of breast cancer. This is essential in order to avoid misconceptions and to frame the correct mind-set about breast cancer among women in Malaysia. Socio-cultural differences and religious practices should be taken into account by health care professionals when advising on breast cancer. Women need to be aware of the risk factors and symptoms of breast cancer so that early diagnosis can take place and the chances of survival improved.

  • 'Beauty(美)' is pursued by many women. It has been expressed through fashion which has become more various as the society became wealthier. This phenomenon can also be found in the Salon Culture of the 17~18th Centuries and in the way that the free-style socialization without specific purposes began by women. Such 'salon culture' fashions have been reproduced in various methods by contemporary fashion designers as they met the trends or as they became the inspiration and source of ideas and were reinterpreted in various styles. Therefore, it is necessary to compare and analyze the studies and expression methods regarding that style's effects on contemporary fashion at a time when the women's salon culture fashion of the 17~18th Centuries is being naturally combined with or restructured to fit in with contemporary fashion. Therefore, the purpose of this study is to analyze, establish the concept of, and summarize the characteristics of the salon fashion style in order to provide fundamental scholarly information and a direction for the fashion design market by establishing a database on the characteristics of both eras based on the characteristics analysis results of the contemporary fashion style and salon culture era. Moreover, this study is also significant in that it will be a helpful tool for new design development to satisfy consumer needs, and in that the comparison analysis on the salon culture and contemporary fashion characteristics can be a useful tool to understand the fashions of both era. The study methods were, first, through a literature review to study the concepts and background of the salon culture. The second method was to setup a style analysis of a period of 4 years and collect visual data from internet fashion information web sites, such as collection books, to collect and analyze the data. Third, the analysis focused mainly on the results of the categorization of images with 20 fashion experts. Fourth, the details of the salon culture fashion style that are used the most in contemporary fashion were summarized and analyzed. Therefore, the results of this study are as follows The development of the socializing culture during the economically abundant era of the 17~18th Centuries became the stepstool for women to enter a new society and at the same time became the background of the development of the salon and related literature. For the characteristics of the salon culture fashion of the 17~18th Centuries, the changes were more significant in the details of the collars, necklines, sleeves, and robes, rather than in partial silhouette changes. It was found that the same fashion repeats in several-century intervals depending on the era changes; however, it has been reinterpreted newly based on consumer preferences and era situations instead of being reused exactly. Therefore, this study will become scholarly and fundamental data to establish the contemporary understanding of the fashion of the salon culture.

Despite such advantages of breast-feeding, its rate has continued to fall year after year in Korea : the 95% rate in 1960's has fallen to 25.4% in 1990. It is known that such a downfall of breast-feeding rate is associated with various factors. The purpose of the study is to examine mother's and nurses' in nursery perception of the impediment factors of breast-feeding : to compare those between of breast-feeding : to compare those between two groups : to provide fundamental data for developing strategies for increasing breast-feeding. The subjects were 45 new mothers from one hospital and the same number of nurses sampled from 3 university hospitals, in Seoul. The data were collected for 11 days from April 12 to April 23, 1994 and a questionnaire was developed based on the interview with 14 nurses and 10 mothers and the literature reviews. Liker's Five-Point Scale was used as measurement. The Data were analyzed using SPSS / PC and descriptive statistics, t-test, ANOVA. The results of study are as follows : 1) Most new mothers get the information about breast-feeding from their mothers, books or newspaper, and relatives in rank than professionals(nurses or doctors). 2) The impediment factors the breast-feeding are categorized as mothers, hospital system, medical personnels and social factors. The most frequently mentioned impediment factors from mothers are 'Difficulty by operational wounds'(3.13), 'Lack of will for breast-feeding'(3.47), 'Insufficient rest and sleep'(3.52) and 'Opposition from husband or his family members'(4.77)in rank. On the other hand those factors from nurses are 'Inadequate nipple condition'(2.37), 'Decreasing milk secretion given medicine after operation'(2.63), 'Mothers knowledge deficit by poorly prepared education'(2.79) and 'Mothers abhorance of breast-feeing'(3.87) in rank. 3) As for the hospital system, the highly perceived impediment factors by mothers are 'Seperation of baby from mother after birth'(2.78), 'Lack of space for breast-feeding in the hospital'(2.93), 'Lack of facility for informing the time for breast-feeding'(3.18) and 'Because of babys' preference artificial nipple by being accustomed to it in hospital(3.97), in rank. Meanwhile, those from nurses are "Seperation of baby from mother after birth",(1.92), "Inconsistency between hospital's nursing time and mother's breast secretion time" scretion time(2.97), "Lack of space for breast-feeding in the hospital"(3.39), and "Lack of facility for informing the time for breast-feeding"(3.74) 4) As for the medical personnels, the highestly perceived Impediment factor from mothers in "Lack of professional nurses for breast-feeding"(2.96), and the lowestly perceived one is "Doctors' reluctance"(4.75). Nurses perceived same as mothers, too. 5) As for the social factors, the highestly perceived impediment factor by mothers and nurses is "Inconvience of social activities"(2.83) and the lowestly ones are "The sense of self-sacrifice"(4.22) by mothers, and "The sense of old fashioned"(4.13) by nurses. 6) The difference of the perception of impediment factors between mothers and nurses is statistically significant only in mother factor.

  • I hereby have gained the following results by investigation and classification according to the contents of Masterial theses of 1015 volumes and Doctorial theses of 288 volumes, which have collected at their central libriaries, of theses which have published, until 1991, at Oriental Medical College of Kyunghee Univ., Kyungsan Univ., Dongguk Univ. and Taejon Univ. 1. The laboratory theses are more plentiful in number than those of literatural or clinical ones, especially more outstanding trends in the case of doctors. 2. In clinical theses, clinical obserbation was high frequnt in master and accupunture in doctor. 3. In laboratory theses, the usage of pharmacy was more frequnt than that of accupuntures or moxibutions. 4. In laboratory theses, it was more plentiful the case of being taken ill before experiment. 5. In experimental method, the drugs were more used complexed or complexed extract, in the case of accupunture, the methods were more adopted by general accup. and aqureaccupunture. 6. In laboritory theses, theses was abundant of no description of normal, control and laboratory groop. 7. It was the great number wi thin a day in the laboratory terms, the rats were most adopted as the objects of lab., in the number of lab method, doctor's was more plentiful than master's. 8. In literatural theses, there was expressed high frequnt trends of study of china, in era, Chosun dynasty in korea and Jin-Han in china. 9. The theory and books were mainly adopted as objects of theses study in the field of literature. 10. In another theses, there was many investigation of contents and drug and sign of illness were main object of study. 11. Laboratory theses had totally more reference and quotation than those of other theses. According to the above results, the number of laboratory theses are superior than clincal and literature theses, other study or statistical theses. But unfortunately they were not enough the transmission of meaning of theses and contribution of learning, beacuse how to do theses was not uni form and description was not evident. So afterward I think it is needed more careful attention and study in the method of theses works.

  • Purpose - Before the economic reforms, the Chinese communication industry was poorly developed. After China's entering to WTO, the Chinese market were gradually opened, domestic companies will be faced with more and more pressures of competition from the world rival countries. As time goes on, the overseas telecommunications companies will occupy the Chinese market with the opening of China Telecommunications market to outside. So this paper focuses on problems and development methods based on the research about the present situation and development methods of communication industry(communication manufacturing industry and communication manufacturing industry) in China. Research design, data, and methodology - This study analyzed the policies of China's entering to WTO. This paper observed previous researches and made an empirical research on Chinese communication industry based on the governmental policies, strategies, books and previous papers with several kinds of clear data announced formally by China authorities. Results - Most recently, reorganization of the communication industry has brought good opportunities for the development of the communication manufacturing enterprises. This paper analyze policy changes of Chinese communication industry, the status of communication manufacturing industry and communication service industry. Finally, this study for further research analyzes the existing problems and puts forward some practicable measures to solve them. Conclusions - Looking ahead, with China's rapid economic development and steady deepening of reform and opening-up, the Chinese communication industry is faced with an even broader prospect of development. Chinese communication industry will be become the pillar one in national economy after 10 years development. Foreign communication companies accelerated investment and progresses to Chinese information and communication markets. Positive ones are more foreign investment, export increase, domestic innovation, communication industry made steep growth. But negative ones are obstacles of domestic companies' development and jobless rate increase etc. Second communication manufacturing industry made good development, but computer and TV related industry made decline in growth. Third, market sizes of internet and mobile services are growing but the size of wired communication services is downsizing gradually. To overcome them, the studies of components or parts of communication manufacturing industry are needed individually. Second China Unicom, China Telecom, China Mobile etc. are Chinese representatives. The sales volumes are very similar at the beginning, but now they are different and make big differences. So the analysis about, their differences and its impact, are needed.

  • As many Korean libraries has begun to be automated and become a part of the worldwide, open library system, they need a new management. Therefore, the purpose of this paper is to explore the library management in automated libraries and to establish a theory of the library management in information society, The automated libraries could be well explained by the systems theory and the environment of the libraries could be well explained by the contingency theory, The following hypothesis were set to direct this research. 1. As the libraries are automated and become a part of one big, worldwide library system, the libraries interact closely with the environment so that the library and the environment become one. 2. As the libraries are automated and become a part of one big, worldwide library system, the librarians need to work in the environment for the library networks, standardization of cataloging, or government information policy making. 3. As the libraries are automated and become a part of one big, worldwide library system, the librarians only manage the library, The various other library staffs take over the traditional library services directly related to books. The data were gathered from the research done previously, Also the date were collected from the American and Japanese libraries. The findings were as follows: The environment of the library integrated all types of the library services such as school library, university library, etc. And it also integrated all the services of the media centers and the press centers, etc. to library services. And the new library services began in the environment. Librarians worked for these new services. In the library, the librarians distingushed the library system from the environment by planning : mission, goal, objectives, policy, procedures and rules. Library organization became temporary such as forming task forces or matrix or free form. The environment controlled the library. Staffs were controlled by plans or computers. And the professional librarians were controlled by their ability to solve problems raised outside the libraries. Library leaders brought in the technology to the library from its environment. The librarians led the formal and informal organizations so that the staffs cooperated well in their work. And librarians tought the library procedures to the partime workers or the temporary staffs. Participative management and management by objectives were the means of motivating staffs. Budget was based on the ever changing environment. The zero based budget method was applied. Therfore, in the information society, the professional librarians become the able managers in the library and global librarians in the environment.
