  • Purpose: This study aimed to provide, as a basic material, the experiences of endoscopy in diagnosis and treatment of tumorous conditions in the upper gastrointestinal tract in children. Methods: The objects were 26 patients diagnosed as having tumorous conditions in the upper gastrointestinal tract among 1,283 patients who underwent upper gastrointestinal endoscopic examination at the Department of Pediatrics, Pusan National University Hospital, from January 1994 to July 2004 retrospectively. The characteristics of patients, the chief complaints for endoscopic examination, the sorts of tumors diagnosed, the endoscopic findings of tumors, and the treatment of tumors were analysed. Results: 1) Eleven male and fifteen female were included, whose mean age was $6.93{\pm}4.02years$. 2) The chief complaints for endoscopic examination were abdominal pain (80.7%), vomiting or nausea (30.8%), and gastrointestinal beeding (30.7%) in order. 3) Six cases of ectopic pancreas, five cases of sentinel polyp, three cases of papilloma and vallecular cyst, two cases of Brunner's gland hyperplasia and gastric submucosal tumor, one case of gastrointestinal stromal tumor, duodenal intramural hematoma, T cell lymphoma, lipoma, and Peutz-Jeghers syndrome were diagnosed by endoscopy with or without biopsy. 4) The location of tumors was in the pharynx (19.2%), esophagus (7.7%), gastro-esophageal junction (23.0%), stomach (30.7%) and duodeneum (26.9%). 5) The size of tumors was less than 10 mm in 53.8%, 10~20 mm in 26.9%, more than 20 mm 19.2%. 6) Treatments for tumors included resection by laser, surgical resection, endoscopic polypectomy with a forcep or snare, and observation 7) There was no significant complication. Conclusion: Various and not a few tumors were found in the upper gastrointestinal tract. The endoscopy was accurate, effective, and safe means for diagnosis and treatment of those lesions in children.

  • The agriculture of Korea was begun in the neolithic era partly and generalized around 4,000 B.C. Discovery of acorn and stoneworks used in agriculture in neolithic era in 8,000 B.C to 6,000 B.C suggests that prehistoric ancestors of Korean night use acorn, hazel-nuts, and haws, etc. as foods. Cultivation of chestnuts, peaches, plums, pears, and japanese apricots was found in Mahan, the tribal states, and in the period of three kingdoms and Balhae dynasty too. In the period of Koryo, pears, plums, japanese apricots, pine nuts, apricots, grapes, jujubes, gingko nuts, oranges, and citrons were cultivated and used in diet. Sejongsilrokjiriji(1454), a geography of the early chosun, and Sinjungtonggukyojisungnam(1492) show that they cultivated almost all fruits we are now cultivating such as hazel-nuts, haws, nutmeg nut, and so on. Loquats seem to be brought in the early chosun era and figs around 16th century. Pecans, sweet cherries were brought around 1,900 and recently tropical fruits like kiwis were brought in and used in a large scale. In addition, Some fruits were used in medical treatments. Fruits increase the pleasure of the diet and sometimes they are used as a measure of a standard of living. Fruits have been improved and used for a long time, their status in our diet will be maintained resolutly.

  • Multi-screen service is a service that consumes more than one media in a number of terminals simultaneously or discriminately. This multi-screen service has become useful due to distribute of smart TV and terminals. Also, in case of hybrid broadcasting environment that is convergence of broadcasting and communication environment, it is able to provide various user experience through contents consumed by multiple screens. In hybrid broadcasting environment, scene composition technology can be used as an element technology for multi-screen service. Using scene composition technology, multiple media can be consumed complexly through the specified presentation time and space. Thus, multi-screen service based on the scene composition technology can provide spatial and temporal control and consumption of multiple media by linkage between the terminals. However, existing scene composition technologies are not able to use easily in hybrid broadcasting because of applicable environmental constraints, the difficulty in applying the various terminal and complexity. For this problems, HTML5 can be considered. HTML5 is expected to be applied in various smart terminals commonly, and provides consumption of diverse media. So, in this paper, it proposes the scene composition and multi-screen service technology based on HTML5 that is expected be used in various smart terminals providing hybrid broadcasting environment. For this, it includes the introduction in terms of HTML5 and multi-screen service, the method of providing information related with scene composition and multi-screen service through the extention of elements and attributes in HTML5, media signaling between terminals and the method of synchronization. In addition, the proposed scene composition and multi-screen service technology based on HTML5 was verified through the implementation and experiment.

  • Purpose: DNR order is generally accepted for cancer patients near the end of life at Hospice Ward. It means not only no CPR when cardiopulmonary arrest develops but no aggressive meaningless medical interventions. Usually on admission, we discuss with the patients' family about DNR order at the Hospice Ward. Recently, we experienced a terminal lung cancer patient who had been on the ventilator for two months after pulmonary arrest. CPR and artificial ventilation were performed because patient's family refused DNR order. There is no consensus when, who, and how DNR order could be written for terminal cancer patients in Korea, yet. Methods: Hospice charts of 60 patients who admitted between Jan and Jun 2003 to Hospice Ward were reviewed retrospectively. Results: The median age was 66(range $31{\sim}93$) and there were 31 males and 29 females. Their underlying cancers were lung (12), stomach (12), biliary tract (7), colon (6), pancreas (4) and others (19). The persons who signed DNR order were son (22), spouse(19), daughter (16) and others (3). But, there was no patients who signed DNR order by oneself. Thirty families of 60 patients signed on day of admission and 30 signed during hospitalization when there were symptom aggravation (19), vital sign change (4), organ failure (3) and others (4). There were 13 patients who died within 5 days after DNR order. Most of patients died at our hospice ward, except in 1 patient. The level of care was mostly 1, except in 2 patients. (We set level of care as 3 categories. Level 1 is general medical care: 2 is general nursing care: 3 is terminal care.) Conclusion: We have to consider carefully discussing DNR order with terminal cancer patients in the future & values on withholding futile intervention.

  • Arsenic and its compounds vary in their toxicity according to the chemical forms. Inorganic arsenic is more toxic and known as carcinogen. The provisional tolerable weekly intake (PTWI) of $15{\mu}g/kg$ b.w./week established by the Joint FAO/WHO Expert Committee on Food Additives (JECFA) has been withdrawn, while the EFSA panel suggested $BMDL_{0.1}$ $0.3{\sim}8{\mu}g/kg\;b.w./day$ for cancers of the lung, skin and bladder, as well as skin lesions. Rice, seaweed and beverages are known as food being rich in inorganic arsenic. As(III) is the major form of inorganic arsenic in rice and anaerobic paddy soils, while most of inorganic arsenic in seaweed is present as As(V). The inorganic arsenic in food was extracted with solvent such as distilled water, methanol, nitric acid and so on in heat-assisted condition or at room temperature. Arsenic speciation analysis was based on ion-exchange chromatography and high-performance liquid chromatography equipped with atomic absorption spectrometry and inductively coupled plasma mass spectrometry. However, there has been no harmonized and standardized method for inorganic arsenic analysis internationally. The inorganic arsenic exposure from food has been estimated to range of $0.13{\sim}0.7{\mu}g/kg$ bw/day for European, American and Australian, and $0.22{\sim}5{\mu}g/kg$ bw/day for Asian. The maximum level (ML) for inorganic arsenic in food has established by EU, China, Australia and New Zealand, but are under review in Korea. Until now, several studies have conducted for reduction of inorganic arsenic in food. Inorganic arsenic levels in rice and seaweed were reduced by more polishing and washing, boiling and washing, respectively. Further research for international harmonization of analytical method, monitoring and risk assessment will be needed to strengthen safety management of inorganic arsenic of foods in Korea.

  • With the introduction of digital technology since the late 1970s, we have been shifting from the industrial era into the information age. New communication systems have changed our concept of reality. Korea has a wealthy communication heritage with its own language and alphabet. However, Korean typography today has struggled to keep its originality, and does not hold up well to international standards. Korean contemporary typography is not efficient for communicating. It is not orderly, organised and simple. It has currently become complicated and decorative. Moreover, many young designers are attracted by imitations of western trends. It is now time for Korea to reveal its own identity. How can it develop a new typographic language that is more sympathetic to Korean tradition\ulcorner How will Korean information design produce a contemporary style with international relevance that contributes to world culture\ulcorner This thesis will be developed a new Korean typographic language that relies more on Korean traditions. Simultaneously, in this thesis will be examined Swiss typography as a relevant style for a new Korean typography to incorporate. Swiss typography maintained a similar philosophy to Korean tradition with its emphasis on clarity and simplicity. This study will be explored the potential of creating a contemporary Korean typographic solution which combines the traditions of Korea with the clarity of Swiss typography. The first attitude of the new typographic language should focus on legibility. The second condition of the new typographic philosophy based on the ability of designers is interpretation of context. The third concept of the new language is founded on an objective, rational design attitude. The final mental attitude of the new typographic language should feel a deep obligation to traditions. It is crucial time for Korean alphabet to establish a relevant standard rather than goes uncritically with the international current. Korea has had worthy traditions. It is suggested that the answers to 'good design' lie in the study of Korea's own history. Simultaneously, the research of Swiss design which is a

  • The upcoming century is a knowledge based society which did not exist before which requires creative ability to solve problems. Therefore, it is necessary to Provide a creative program of problem solution in order to match this global trend The creativity of problem solution means the ability to solve a problem using previous ideas in an advanced way or develop new ideas. Creative education is especially important for infants. Because the young mind is where fresh ideas preside and can frame-work the early stage of life like a blank sheet of paper. The Infant-Early Child Creative Development Institute. as an adhesive institute at Yeungjin College, develops various programs that integrate methods which match current trend in this era and also start the Creative Promotion Test with 2,000 Families for the expansion of creative education from the baseline as an alternative method. The infants tested in the creative test will find ways of problem solution through animation beam projects for their given situation and also discuss the problems with their family members. Through these processes the infant and family members will complete the creative structures to solve the problems using limited materials given by the institute, and the final product will be evaluated as objective results. The final evaluation of the test will also be considered the teamwork of family cooperation and the attitudes of participants as well as the product of problem solution. The criterion of the evaluation is to be considered both a creative way of thinking and creative attitudes. Because the score counts were conducted manually it delayed the selection of awarded students who took the test. Also, we found that some parents have difficulty in accessing information to find the score through homepage from the computer. this Problem might be corrected in the future plan. Like Freud's saying, if human character and exploring attitudes during the early stage of a child, a person's creativity is composed their infant period as their basic foundation. Therefore, the family wh first environment the infant encounters will be treated as a prima when making basic structure. From this viewpoint, this creative test work as a festival of creativity fare with 2,000 families.

  • This study was carried out to create a momentum for interest and understanding of local foods and provide base line data for the presentation of future effective development direction by investigating and researching cognitive characteristics, intake frequency, and preference about local foods targeting Pohang citizens. As a result of the investigation on intake frequency and preference of Pohang's local foods, in almost every item such as "gwamegi", "mul-hoe", "Guryongpo daege", "sashimi noodles", "mori noodles", "pidegi cuttle fish", "mulgomtang", "homchibap sikhae", "jesabap sikhae", "whale meat", "gaebokchi", "duchichijjim", "octopus sashimi", "roundnose flounder sashimi", "round flounder jorim", "fried round flounder", "gunsu sorasanjeok", "raw mustard muchim", "miyeongui dish", "sigeumjang", "chives dish", "rolled chives egg", "gokgang spinach", "pine dish", "yellow bean leaves muchim", "pickled green bean leaves", "green bean leaves watery kimchi", "Pohang sunrise bread", "black stone eel dish", "chili jjim", "red-pepper leaves namul muchim", "wild greens bibinbap", "acorn jello muchim", "oimiyeok changuk", "dongdongju", etc., significant differences were shown at the significance level of p<0.05~p<0.001. About understandings, views, development prospects, and development value and so forthof Pohang's local foods, more than 80% of respondents were positive, and in the questions asking concerns about local foods, more than half of the respondents gave a positive opinion, citing that they "have a little interest", and "tend to have an interest". Therefore, it can be seen that the future of local foods is bright. In the future, it is required that various cultural events related to local foods are held, a number of promotions are carried out, specialization of stores is distributed, and, at the same time, local foods are developed and generalized to suit modern sense, maintaining traditional taste in order to become global foods, as well as thedeformation of recipes.
