  • The purpose of this study is to select the study area, which will be formed into Daegu Science Park as an national industrial complex, and to assess the landscape value based on biotop classification with different polygon forms, and to develop and computerize Biotop Value Assessment Tool (B-VAT) based on GIS. The result is as follows. First, according to the result of biotop classification based on an advanced analysis on preliminary data, a field study, and a literature review, total 13 biotop groups such as forrest biotop groups and total 63 biotop types were classified. Second, based on the advanced research on landscape value assessment model of biotop, we development biotop value assessment tool by using visual basic programming language on the ArcGIS. The first application result with B-VAT showed that the first grade was classified into 19 types including riverside forest(BE), the second grade 12 types including artificial plantation(ED), and the third class, the fourth grade, and the fifth grade 12 types, 2 types, and 18 types respectively. Also, according to the second evaluation result with above results, we divided a total number of 31 areas and 34 areas, which had special meaning for landscape conservation(1a, 1b) and which had meaning for landscape conservation(2a, 2b, 2c). As such, biotop type classification and an landscape value evaluation, both of which were suggested from the result of the study, will help to scientifically understand a landscape value for a target land before undertaking reckless development. And it will serve to provide important preliminary data aimed to overcome damaged landscape due to developed and to manage a landscape planning in the future. In particular, we expect that B-VAT based on GIS will help overcome the limitations of applicability for of current value evaluation models, which are based on complicated algorithms, and will be a great contribution to an increase in convenience and popularity. In addition, this will save time and improve the accuracy for hand-counting. However, this study limited to aesthetic-visual part in biotop assessment. Therefore, it is certain that in the future research comprehensive assessment should be conducted with conservation and recreation view.

  • In many organisms, trehalose acts as protective metabolite against harsh environmental stresses, such as freezing, drought, nutrient starvation, heat and salt. Herein a cDNA (designated as GbTPS, GenBank Accession Number AY884150) encoding a trehalose-6-phosphate synthase homologue was isolated and characterized from the living fossil plant, Ginkgo biloba, which is highly tolerant to drought and cold. GbTPS encoded an 868-amino-acid polypeptide with a predicted isoelectric point of 5.83 and molecular mass of 97.9 kD. Amino acid sequence alignment revealed that GbTPS shared high identity with class II trehalose-6-phosphate synthase homologues (67% identical to AtTPS7), but had only 17% and 23% of identity with OstA from Escherichia coli and ScTPS1 from S. cerevisiae, respectively. DNA gel blot analysis indicated that GbTPS belonged to a small multi-gene family. The expression analysis by RT-PCR showed that GbTPS expressed in a tissue-specific manner in G biloba and might involve in leaf development. GbTPS was also found to be induced by a variety of stresses including cold, salt, drought and mannitol.

  • The animation is in a boom as the one of rising media content industry of 21st century. So it is very affective to education. For example, in primary or secondary schools, there are extra-animation class after school, and in universities, there are a lot of the department of animation nowadays. In every years, a number of high-educated professionals are coming to the manpower market. This was an affirmative phenomenon for many animation companies to upgrade from OEM(Original Equipment Manufacturing) system to very creative system. They might believed that young, well-educated animators have qualified skills, and creative mind. But, 10 years later, now, there is few professionals who was well-educated in system of Korean animation. Companies still can not hire enough animators. Even if they can find an high-educated person, this person do not have enough skills to do his or her works, so companies need to re-educate this animator for awhile. But, why is very hard to find a skillful new animator? From this question, we will talk about educational condition of animation departments, and condition of employment to markets. And then, we will find the causes of problems which give bad effect to lack of manpower. Finally, we will summarize about policies for supporting animation, so hope to contribute for making better atmosphere for creating animations.

  • Background: This study was designed to demonstrate the peripheral effect of ketamine on the synovia of the knee joint and evaluate the analgesic effect of an intraarticular ketamine injection following knee arthroscopy. Methods: In a double blind randomized study, 80 ASA class 1 or 2 patients were selected for elective arthroscopic knee surgery. The patients received either 20 ml of normal saline (Group C, n = 19), 20 ml of 0.5% ropivacaine (Group R, n = 21), 1 mg/kg of ketamine mixed with 20 ml of normal saline (Group K, n = 20) or 1 mg/kg of ketamine mixed with 20 ml of 0.5% ropivacaine (Group RK, n = 20), intraarticularly, just prior to wound closure. Postoperative pain was evaluated using a visual analogue scale (VAS 0 to 100) score at 1, 2, 6, 12, 24 and 48 hours after the intraarticular injection, with the side effects found in the four groups also evaluated. The patients' requests for rescue analgesic were recorded, total doses of tarasyn calculated and the overall patient satisfaction also evaluated. Results: The difference in the VAS scores for all time periods was not significant. The number of patients receiving rescue analgesics and the total doses received in Group C were greater than those for the other groups, but this was not significant. No side effects were observed in any of the patients. Conclusions: Ketamine and local anesthetics have been reported to have peripheral analgesic effects, with variable duration in the measurements of pain and hyperalgesia. However, we failed to demonstrate a peripheral analgesic effect on postoperative arthroscopic pain.

  • The general meal intake survey in two regional areas(Seoul and Andong in Kyungsangbuk province) was conducted to investigate what the Korean favorite dishes are, as a part of study on their blood glucose responses. The survey was carried out to fill up the 45 kinds of questionnaires to adults over 20 years old. The age of subjects was evenly distributed from twenties to fifties and 54% of them was middle class, whose monthly income was between a million won and two million won. The 72% of subjects mixed cereals(mainly barley, soybean) with rice but about 28% did not. Domestic meals except general Korean meals were bibimbab and kimblb. Major noodles at home was ramen and kalgugsu(home made noodle) and 50% of the subjects took the noodle with small amounts of steamed rice. The 41% of subjects took the gug(Korean soup) in every meal and the major soup was vegetable doengang soup, sea mustard soup, beef soup and soybean sprout soup in order. The 87% of subjects took either soup or pot stew, and doenjang pot stew and kimchi pot stew were mainly used. The number of side dishes except soup, pot stew and kimchi was 3∼4. The side dishes in meat was cooked mainly with beef and pork. The favorite cooking type of fish is roasting one. Two kinds of kimchi were served in every meal and the major kimchi was cabbage kimchi, kkagdugi(radish cube kimchi), yulmu kimchi in order. The major meal of eating out was galbitang and bibibbab in Korean style, jjajangmyon in Chinese one, pork cutlet in western one and hamburger as a fast food.

  • A sanitary survey was conducted to evaluate the water quality and mussel (Mytilus edulis) conditions of two administrative shellfish growing waters: those designated as shellfish growing water for export, and adjacent waters on the east coast of Changseon Island, Namhae, Korea. In all, 1,656 seawater and 166 mussel samples were collected at 46 stations for seawater and five stations for the shellfish from January 2007 to December 2009. Both seawater and mussels were examined for total coliforms and fecal coliforms. The standard plate count and most probable number of Escherichia coli were also determined for the shellfish samples. The range of the geometric means and the estimated 90th percentiles of fecal coliform for seawater samples at each station were <1.8-4.1 MPN/100 mL and <1.8-22.3 MPN/100 mL, respectively. The sanitary conditions for both shellfish growing areas, the designated shellfish growing area and adjacent area in Changseon, met the 'Approved area' criteria of the United States National Shellfish Sanitation Program. The range of E. coli detected in mussels in these areas was <20-500 MPN/100 g; and only 3 of 166 samples exceeded 230 MPN/100 g, the European standard for the consumption of raw bivalves. Therefore, the mussel farms in the Changseon area are classified as 'Class A' according to criteria set in European Community regulations. However, the levels of E. coli in mussels in parts of the designated shellfish growing area and adjacent area exceeded the bacterial limits after rainfall exceeding 45 mm. Further studies are needed to fully define the conditions leading to a temporary closure to harvest after a rainfall event.

  • This study examined the effects of a prenatal education program of labor and delivery experience for primigravidas in mid-pregnancy. This investigation was designed as a one group pre-post quasi-experimental study, aiming to determine the effects of prenatal education on anxiety, confidence and knowledge in delivery by demonstrating knowledge and actual situations including understanding labor, breast-feeding, baby care and others, and experiencing the education program. Subjects were collected randomly from an on-line club in D city. The simulation education proceeded for 2 hours a week from April to June, 2014, and there were 6 sessions each in the first and second periods. We included 35 primigravidas who attended all 6 sessions. The data was analyzed using descriptive statistics, exploratory factor analysis and a paired t-test. According to the study results, the subjects showed a significant difference in knowledge in delivery (t=-9.07, p<001), confidence in delivery (t=-9.00, p<001) and anxiety (t=14.39, p<001) after participating in the prenatal education program. An evaluation of satisfaction revealed experience to be the most differentiating factor, and the simulation experience was identified as most effective. The desired appropriate number of class sessions was 4 times, and 88.6% of the pregnant women intended to attend the program at their next birth, indicating a high response rate.

  • Currently, two-dimensional culture is the main keyword in Chinese contents market. In China, many capital and economic giants have entered into two-dimensional cultural market because the number of users and the interest of the public for two-dimensional culture are increasing day by day. The reason for the rise of the two-dimensional culture into the mainstream culture is not only the switching of the mainstream consumer class but also Two-Dimensional Culture forms a huge industrial chain covering many areas including movies, performances and theme parks in addition to ACGN (Animation, Comic, Game and light Novel), the second is that more people are participating in Two-Dimensional Culture due to the specific audience with high social environment and loyalty and the third is looking for the role of the users in Two-Dimensional cultural content from three characteristics, such as strong cultural prevalence. This study analyzed the Chinese two-dimensional cultural environment through PEST(Political, Economic, Social and Technological analysis) In addition, as the ecological environment and communication method of Two-Dimensional Culture users changed, the users became active participants and the second producers of contents. I examined the way of using the users' contents through the phenomenon of 'Barrage'. Therefore, this study discussed the appropriate development path for the user-oriented contents industry in the Chinese Two-Dimensional cultural environment.

  • The ABR service class provides feedback based traffic control to transport bursty data traffic efficiently. Feedback based congestion control has first been studied to be applied to unicast connections. Recently. several congestion control algorithms for multicast connections have also been proposed as the number of ABR applications requiring multicast increases. With feedback based congestion control, the effectiveness of a traffic control scheme diminishes as propagation delay increases. Especially for a multicast connection, a remote destination may suffer unfair service compared to a local destination due to the delayed feedback. Amelioration of the disadvantages caused by feedback delay is therefore more important for remote destinations in multicast connections. This paper proposes a new switch behavior to provide effective feedback based mathc control for rentoh destinations. The proposed switches adjust the service rate dynamically in accordance woth the state of the downstream, that is, the congestion of the destinaion is immediately controlled by the nearest apstream switch before the source to ramp down the transmission rate of the connection. The proposed switch has an implementation overhead to have a separate buffer for each VC to adjust the service rate in accordance with a backward Rm cell of each VC. The buffer requirement id also increased at intermediate switches. Simulation results show that the proposed switch reduces the cell loss rate in both the local and the remote destinations and slso amelioratd the between the two destinations.

  • In training a classification model using machine learning, the acquisition of training data is a very important stage, because the amount and quality of the training data greatly influence the model performance. However, when the cost of obtaining data is so high that it is difficult to build ideal training data, the number of samples for each class may be acquired very differently, and a serious data-imbalance problem can occur. If such a problem occurs in the training data, all classes are not trained equally, and classes containing relatively few data will have significantly lower recall values. Additionally, the reliability of evaluation indices such as accuracy and precision will be reduced. Therefore, this study sought to overcome the problem of data imbalance in two stages. First, we introduced weighted accuracy and weighted precision as new evaluation indices that can take into account a data-imbalance ratio by modifying conventional measures of accuracy and precision. Next, oversampling was performed to balance weighted precision and recall among classes. We verified the algorithm by applying it to the problem of facies classification. As a result, the imbalance between majority and minority classes was greatly mitigated, and the boundaries between classes could be more clearly identified.
