  • This study suggests the necessity of behavior analysis as changes to a park environment to reflect user desires can be implemented only by grasping the needs of park users. Online data (blog) were defined as the basic data of the study. After collecting data by 5 - year units, data mining was used to derive the characteristics of the time series behavior while the significance of the online data was verified through social network analysis. The results of the text mining analysis are as follows. First, primary results included 'walking', 'photography', 'riding bicycles'(inline, kickboard, etc.), and 'eating'. Second, in the early days of the collected data, active physical activity such as exercise was the main factor, but recent passive behavior such as eating, using a mobile phone, games, food and drinking coffee also appeared as a new behavior characteristic in parks. Third, the factors affecting the behavior of park users are the changes of various conditions of society such as internet development and a culture of expressing unique personalities and styles. Fourth, the special behaviors appearing at Olympic Park were derived from educational activities such as cultural activities including watching performances and history lessons. In conclusion, it has been shown that people's lifestyle changes and the behavior of a park are influenced by the changes of the various times rather than the original purpose that was intended during park planning and design. Therefore, it is necessary to create an environment tailored to users by considering the main behaviors and influencing factors of Olympic Park. Text mining used as an analytical method has the merit that past data can be collected. Therefore, it is possible to form analysis from a long-term viewpoint of behavior analysis as well as to measure new behavior and value with derived keywords. In addition, the validity of online data was verified through social network analysis to increase the legitimacy of research results. Research on more comprehensive behavior analysis should be carried out by diversifying the types of data collected later, and various methods for verifying the accuracy and reliability of large-volume data will be needed.

  • This study aims to understand the tendencies and characteristics when constructing landscape architectural archives in the United States, and to find implications for creating Korean landscape architectural archives. Focusing on seven American landscape architectural archives operated by public institutes, universities, and research institutes, this study examines the background, mission, scope, subject, acquisition, arrangement, and application of the programs in the archives. The results show that the characteristics of the American landscape architectural archives are as follows: first, the recognition of the value and importance of the landscape plays a major role in the establishment of archives; second, the purpose of the archives is to educate and encourage people to find diversity or significance of landscapes; third, the subject and scope of the archives vary according to the purpose of each operating institution; fourth, the main acquisitional method is to receive a donation and to purchase materials or documents; fifth, the classification systems of each archive differs depending on the subject and scope; and sixth, the archives were built on the basis of participation and collaboration with various experts and organizations with stable and sustainable financial resources. These characteristics offer three implications for constructing landscape architectural archives in Korea. First, a long-term vision for landscape architectural archives and the establishment of differentiated themes are required. Second, appropriate methods of material collection and systems of classification, recording, and digitization are necessary and therefore research and pilot archives are required. Third, it is necessary to secure the sustainability of archives by developing ways to utilize the archives in connection with academic and educational programs, thereby securing financial resources and allowing for the establishment of appropriate policies. As basic research, this study is significant as it provides a basis for further research concerning the development of landscape architectural archives in Korea.

  • One of the familiar medical facility that most people reach easily in Korea is the drug store. In Korea, it is possible to purchase all kinds of common drugs without physician's prescriptions, which caused some problems. In other words, such treatment without professional supervision has led to medical, social and economical problems. In view of the above, this study is aimed at revealing the actual status of long-term use of drugs in some urban residents. Long-term use of drugs is operationally defined as using certain drugs at least once a week for more than 3 months. This survey took the residents of Guro 6-Dong where was one of the target areas for Community Health Development Project managed by Korea University as a target population. A sample of 1,517 residents was selected by the multistage sampling method. The interview was conducted on September 21st and 22nd in 1985. The object of this study was to compare the result with that of the rural area which was obtained by the same method, tools and research team, prior to this study in 1984. The results were as follows; 1) The age-standardization of the study showed that 97 per 1,000 urban residents were actually on long-term drug use. The prevalance of long-term use is high in accordance with aging and low with education level. 2) Out of 1,000 urban samples the most popular item involved in the long-term drug use was antipyretic-analgesic-antiinflammatory drug (26), and next in order was vitamin (23), antibiotics (13), digestives (10) and antacids (7). In the rural samples as for compare, that was antipyretic-analgesic-antiinflammatory drug (100), antacids (36), digestives (23), adrenocortical hormones (12) etc. 3) With antipyrctic-analgesic-antiinflammatory drugs, 50% of the urban samples were taking for more than a year, whereas such were 82.7% of the rural samples. Using such a high percentage of antipyretic-analgesic-antiinflamatory drugs in the rural residents is probably due to the high prevalence rate of musculo-skeletal diseases. 4) The urban long-term drug users of antipyretic-analgesic-antiinflammatory drugs were influenced mostly by the mass media (43.6%), next in order was pharmacist (35.9%) and physician (10.3%). Comparing with the result from the rural areas the role of mass media was much more influencial in the urban areas. 60% of them consulted with pharmacists, 14.3% with physicians and 25.7% had no history of consultation in the urban samples. 5) Considering the incidence of knowing the possible side-effects of each drug, 28.2% of the urban residents had no recognition about side-effects prior to use antipyretic-analgesic-antiinflammatory drugs. In the rural residents, 29.67o had no knowledge about the side-effects before using the drug. 6) For the solution of the above problems, it is necessary to limit the advertisement of some drugs by the parmaceutical company. And therapeutic drugs which may bring on side effects in case of long-term use should not be sold at drug stores without physician's prescription.

  • This study analyses the business performance according to the business diversification of Korean mass media enterprises from year 2003 to 2006. The conclusions drawn which could be divided into five main parts are the followings: First, newspaper companies pursue unrelated diversification in various industrial areas, in order to gain maximum profit while broadcasting companies exert themselves to provide better service by diversifying the major contents. Second, overall the interviewed companies display a constant decline in profit gained from their major business area thus establishing strategies to broaden their focus on diversification of any sort. Third, the researcher completed group analysis in regard of diversification measure resulting in division of three groups. The group which had the most immense diversification range gained the highest ROE, the lowest ROE volatility, and lesser probability of risk taking. The analysis adresses the companies broadening their business areas by researching and focusing on diversification are relatively stable in terms of the profit they gain. Fourth, the middle level group in terms of sales scale, debts, enterprise history, major share rate and high ROE group carry out diversification progressively. The sales scale affects positively to diversification, while the major share rate affects negatively to diversification. Fifth, in accordance to the research, diversification overall contributes to obtainance of successful outcome. Since there was not an immense amount of studies to be referred in the media area, the researcher interviewed and did panel discussion with numerous strategists and managers who are in charge of diversification of media companies. However, collection of only 4 years of data limits the research to be considered to be a generalized study, and does not reflect time gap between business diversification and business performance. Development is required in future studies to be established regarding the media companies' specificity different to other industries, classified the media companies into media types, and consider the time gap in the diversification activities and business performance.

  • Among every civilized people salt has been recognized as an essential foodstuff to the human society without which even man's survivor is unthinkable. The cultural-anthropological meaning of salt is estimated highly as well, and in geographical perspective salt itself symbolize regional interrelationship. Playing a decisive role in freeing innermost settlement from isolation, salt aiso made a contribution to expanding human habitats. This study tries to reconstruct historica geography of 18th and 19th century surrounding traditional salt-roasting (chayeom). The Joolpo Inlet area which is located on the mid-western coast in Honem Region is selected for study area. Established on the basis of optimum physical geographical conditions such as topography, climate and vegetation, salt-making of Joolpo Inlet area was run dynamically with the sudden turn of events in the 18-19th century which was chacterized as an age of transition from medieval society to modern one. In this paper the writer attempts to clarify mainly following three points: physical conditions and socio-economic background leading to the initiation and later development of roasting of salt in Joolpo Bay; distribution of saltworks; methods of saltmaking. Main points drawn from these analyses can be summarized as follows: of iron pan and cow-drawn tools rendered labour-saving and output growth. 1, Saltworks of Joolpo Inlet area in the 18-19th century were distributed evenly over Kobu, Puan, Mujang and Heungduck counties among which Kobu's was located in Puanmyon - a sort of exclave. All saltworks belonging to above four counties were clasified as most lucrative ones in Honam Region on government archives. In particular, Gumdang saltwork which belongs to Mujang county is noteworthy in that it was first introduced by one Paekje priest in 6th century and therefore it provides a clue to examine the history of salt-roasting of Joolpo Inlet area. In light of the fact that temple or monastery economy, regardless of East and West, has been closely connected with traditional industry, the case of Gumdang is not unusual. 2. The process of saltmaking follows this order: harrowing of salt field exposed to solar heat; construction of saltern mound with saline earth; acquiring of brine by leaching saline earth; roasting of salt. Salterns (saltworks) are consisted with various salt making facilities such as roasting shed, saltern mound, salt field, salt well) salt pit or brine pit) and seawater reservoir. Among them roasting shed which is constructed chiefly with hundreds of pieces of pine tree as a frame and with straw as roof and wall is customarily considered as an unit of saltwork. And inside it is saltpan made of two kinds of materials, that is iron pan or plaster pan. The area attached to one unit of roasting shed is approximately 1 ha, and that of saltern mound is a tenth of it.

  • In a long history of geography, a variety of regional concepts have been suggested to represent the particular situations in each period. Today, post-modem situations, characterized by the development of capitalism and globalization, demand a new variety of regional concepts. The regional characteristics, such as social relations, institutional systems, ideologies and symbolism, are now perceived basically on the level of subjectivity. Currently, it is the most urgent task to integrate many conflicting opinions among a variety of subjects into the one that would seek a voluntary consent from the majority of regional residents. In this paper, it is suggested that the concept of identity is the most efficient in examining and explaining the post-modem trend of a region: variability, subjectivity, mobility, changeability, Finally, it is suggested that a special attention should be paid to the role of institutions, that is institutionalization, in the construction of regional identity, to understand and interpret the cultural-historical aspect of a regional change.

  • Business facilities among domestic architectures have rapidly been constructed along with domestic economic development. It is an important facility taking the second largest proportion next to apartment buildings among current 31 building types of fire department classification of 2012 year for urban architectures. The expected service life of business facilities is 15 years, but 70% of those in urban areas have surpassed the 15 year service life as of the present 2014. Thus, the demand for urgent rehabilitation of such facilities is constantly increasing due to the aging and performance deterioration of the facilities'main finishing materials. Especially, the business facilities are being used for the lease of company office or private office, and such problems as aging and performance deterioration of the facilities could cause less competitive edge for leasing and real estate value depreciation for the O&M (Operation & Management) agent and the owner, respectively. Therefore, an effective planned rehabilitation as a preventive measure according to the standardized repair rate by the number of years after the construction is in need in order to prevent the aging and performance deterioration of the facilities(La et al. 2001). Nonetheless, domestic repair/rehabilitation standards based on the repair rate are mainly limited to apartment buildings and pubic institutions, resulting in impractical application of such standards to business facilities. It has been investigated and analyzed that annual repair rate data for each finishing material are required for examination of the applicability of the repair rate standard for the purpose of establishment of a repair plan. Hence, this study aimed at developing a repair rate computation model for finishing materials of the facilities and verifying the appropriateness of the annual repair rate for each finishing material through a case study after collecting and analyzing the repair history data of six business facilities. The results of this study are expected to contribute to the planning and implementation of more efficient repair/rehabilitation budget by preventing the waste of unpredicted repair cost and opportunity cost for the sake of the business facilities' owners and O&M agents.

  • The aim of this study was to illustrate how STS-related ideas in science education have been developed historically in the context of British education, particularly focused on the period of the 19th century and the first half of the 20th century. It has been hardly considered that the basic ideas of the STS education, one of the two paradigms of current science education together with constructivism, can be traced back to the beginning of the school science education itself. far beyond some of the programs which are largely regarded as the first-developed STS programs in Britain, such as Science in Society and SISCON. The movement of Mechanics' Institute during the first half of the 19th century would be the first systematic attempt to bridge the gap between the knowledge of pure science and its practical applications, although the main target was working-class adults rather than school pupils. At the end of the first half of the 19th century, this application-focused approach of science teaching was echoed in the elementary schools by Richard Dawes, one of the early experimenters of school science. The second half of the century was in large the period of the establishment of science as one of the core elements of school curriculum, mainly by emphasizing the aspect of pure science as a means for mental training. During this period, the elements of STS education-related appeared in the subject called 'Object Lesson' in elementary schools which was practically a separate subject from those of science. After the turn of the century, triggered by the experience of World War I, the growing appreciation of the impacts of science upon society and of the necessity of the teaching of science for wider audience gave a great impact towards two new main movements, i.e. for General Science and Citizen Science. The later illustrates a typical example of the STS movement in school science during the first half of the 20th century, particularly driven by the socialistic ideas towards the relation between science and society.

  • Purpose : Percutaneous cannulation of the central vein in children and infants may be technically difficult and can cause serious complications. There are many techniques to improve the success rate and to decrease the complications in central vein cannulation. This study was undertaken to determine whether audible Doppler guidance can help operators improve the results of central vein cannultion in pediatric ICU. Methods : A total of 46 central vein cannulations were performed using audible Doppler guidance technique. Using an 8-MHz Doppler ultrasound device(Pocket-Dop II. iMex. USA), the artery and the vein were identified by their characteristic Doppler sounds. Results : There was a total of 46 patients with 20 boys and 26 girls, respectively. The mean age was $3years{\pm}45months$(range : 1-156 months). The number of infants was 18 and the mean age was $6.3{\pm}3.8$ months(range : 1-12 months). The most common site of central vein cannulation was the right internal jugular vein(63%). The cannulation was successful in 44 out of 46 procedures(96%). The success rate at the first attempt was 59% with 48% in the patients who had the history of previous cannulation and 70% in the patients who did not, respectively. The success rate in infants was 94%(17 out of 18). The average access time was $5.2{\pm}8.3$ minutes in children contrary to $7.5{\pm}10.3$ minutes in infants. There were no serious complications, but six patients had complications including four hematoma, one arterial puncture, and one pneumothorax. Conclusion : This central vein cannulation using Doppler guidance may improve the success rate of central vein cannulation and decrease the development of serious complications in infants and children.

  • This study examine closely conditions of costume between the Modernized period and Liberation with newspaper materials. Because newspaper generally appear society conditions in those days on rapid and across-the boad basis. The Modernized period is extremely change among history of costum (ordinance prohibiting top knots, allowance of foreign clothes putting on). Because this change have been spontaneously not by internal desired but Western input by the strong nation of imperialism to enclose Chosun, they was accepted by the general public later under the rule of Japaneses Imperialism. Consequently, study of costume play an important part periods between the Japanese annexation of Korea and Liberation. This study apply to newspaper characteric for costume, and closely examine an important costum condition of those days next time, and present costume material in those days that composed the account catalog appeared periods between the first publication(1920) of the Dong A II Bo, and in the year 1945, it is as follows. 1. Foreign clothes of men generally accept the general public on look at from form change, in the 1920's had come short Jackets and narrow throusers into fashion, in the 1930's had come trousers of generous waist band with broads shoulder and long Jackets. Catalog of Major clothes is as follows; Spring coat, Jacket, Vest, Shirt, etc. While pants had come trousers into fashion 2. Functional characteric of Foreign clothes was the possible acceptance of women's foreign clothes. It relate with much discussion to improve Korean development in those days and substitute foreign clothes for Korean clothes because of institence in those days to improve functional clothes life. 3. An improvement women's Korean clothes generally take aim at women's nipple liberation, substitute vest waist for skirt waist, appear seamless one-piece skirt of shade length, and long dress length of Jacket. 4. Children's clothes give an account of functional and sanitary conditions, handling method, washing method. 5. Clothes materials give account of foreign clothes material, artificial silk, furs, cotton fabrics, and etc. 6. Clothes management give an account of washing, keeping method, washing method of foreign clothes, and keeping of furs. 7. The hair generaly had come short hair into fashion in men's case, while accounts on long hair fashion of foreign nation effect in case of women. 8. Describing on beauty care manage primary beauty care, reform, plastic operation, and shade beauty care. Ideal beauty care deal with natural and dignified buauty care. 9. Accesaries (hat, handbag, handkerchief, gloves) change with fashion of clothes, it rapid more than clothes fashion. 10. On encouragement of abolition of white clothes and putting on dyeing clothes, because of economic defect of white clothes, psychology and beauty consequently, white clothes is on the rise abolition. In national level almost substitute dyeing clothes for control and improvement of people of all social standings consequently, dress and its ornaments conditions in those days analyzed account of Dong-A II Bo accept the foreign clothes that introduced internal country of the whole century, and substitute dyeing for white clothes. Costume condition in those days appear the mixed conditions of Korean clothes and Foreign clothes. In the 1920's is the first consideration dress and its ornaments form of Korean clothes. As later goes on foreign is given much weight in the whole clothes life. Account of foreign clothes managemental ways appear in the 1920's, while those facts prove the point that appeared the account that always dealed with concrete content of foreign fashion in the 1930's.
