Webtoon has developed the method that makes it possible to express sound visually. Also we can also hear sound in webtoon through the development of web technology. It is natural that we analyze the sound that we can hear, but we can also analyze the sound that we can not hear. This study is based on 'dual code' in cognitive psychology. Cartoonists can make visual expression on the basis of auditive impression and memory, and readers can recall the sound through the process of memory and memory-retrieval. This study analyzes both audible sound and inaudable sound. Concise analysis owes the method to film sound theory. Three main factor, Volume, pitch, and tone are recognized by frequency in acoustics. On the other hand they are expressed by the thickness and site of line and image of sound source. The visual expression of in screen sound and off screen sound is related to the frame of comics. Generally the outside of frame means off sound, but some off sound is in the frame. In addition, horror comics use much sound for the effect of genre like horror film. When analyzing comics sound using this kinds of the method film sound analysis, we can find that webtoon has developed creative expression method comparing with simple ones of early comics. Especially arranging frames and expressing sound following and vertical moving are new ones in webtoon. Also types and arrangement of frame has been varied. BGM is the first in using audible sound and recently BGM composed mixing sound effect is being used. In addition, the program which makes it possible for readers to hear sound according to scroll moving. Especially horror genre raise the genre effects using this technology. Various methods of visualizing sound are being created, and the change shows that webtoon could be the model of convergence in contents.

Fashion is subjected to newness and change by itself. Fashion trend and tendency which could predict next season akeady indicated that digital and cybel11ation environment lliould be factors in fashion. Changes in future life styles and values caused by digital environment must be variables as fashion objects by themselves. Therefore digital environment of a fashion itself and that all encountered in fashion will not only be an existing situation but also an objective and a factor which must be pursued with fashionable sense in future fashion. Advanced technology and social change in relation to digital environment requires that educational method as well as its content will be changed on the scene of education for future. Thus we should seek an educational direction in fashion design for future society in which digital environment requires new paradigm. Subject to these backgrounds this study has an intension to study the change in fashion extensively influenced by expanded digital environment on a limited situational level of fashion design education and to suggest an educational direction for professional in future fashion design who will serve as a core of fashion area in the future. It is essential that education of professional in fashion for future should be achieved by digital-minded level that eagerly understands and accepts future society in which digital environment will be a main axis. It is necessary for this to make them expetience computers, digital media including CAD program. We have to note that education of digital media is more effective and applicable when accomplished in CAI level which can be related and expetienced with fashion education rather than mere functional training in media themselves. Intellectual creativity will be a vety source of producing values and national competence in 21st centtury. Education of design professional in fashion area must positively accept these environmental charactetistics in future society, as well as deeply reflect the education for the future.

'Technological convergence' is the recent innovation trend which facilitates to solve social crux as well as to generate new industries. Korean government research institutes (GRIs) have taken a pivotal role for economic growth which capitalized on technology-oriented strategies. Recently, the policy interests on the transition of their role and mission towards multidisciplinary research organization is increasingly shed lights. This study regards the collaborative activities as one of the key success factors in the multidisciplinary research. In this sense, this study sets research purposes as follows: First, we intend to define a concept and to confine a scope of multidisciplinary research from the view point of R&D purposes and problem-solving process. Second, we categorize the collaboration and the relevant performances which reflect the characteristics of the multidisciplinary research. Third, we analyze the characteristics of collaborative activities and the effects of strength on the research performances. To this end, this study conducted a survey of 104 research project directors, which have experienced at least one of two types of multidisciplinary research projects through National R&D project or NST (National Research Council of Science & Technology) convergence research project. Then, we conducted regression analysis by utilizing the survey results in order to verify the relation between the collaborative activities and the performances. As results of analyses, first, the diversification of collaboration partners was a salient factor in the process of knowledge creation. Second, collective works among the researchers in similar area and domain enhanced mission-oriented technology development projects such as patent creation or technology transfer. Third, we verified that the diversity of created knowledge and the degree of relation continuity between researchers increased in the condition of guaranteeing individual researcher's independence and autonomy as well as sharing various technological capabilities. These results provide the future policy directions related to the methods to measure the collaboration and performance analysis for multidisciplinary research.

Social media is an emerging issue in content services and in current business environment. YouTube is the most representative social media service in the world. YouTube is different from other conventional content services in its open user participation and contents creation methods. To promote a content in YouTube, it is important to understand the diffusion phenomena of contents and the network structural characteristics. Most previous studies analyzed impact factors of contents diffusion from the view point of general behavioral factors. Currently some researchers use network structure factors. However, these two approaches have been used separately. However this study tries to analyze the general impact factors on the view count and content based network structures all together. In addition, when building a content based network, this study forms the network structure by analyzing user comments on 22,370 contents of YouTube not based on the individual user based network. From this study, we re-proved statistically the causal relations between view count and not only general factors but also network factors. Moreover by analyzing this integrated research model, we found that these factors affect the view count of YouTube according to the following order; Uploader Followers, Video Age, Betweenness Centrality, Comments, Closeness Centrality, Clustering Coefficient and Rating. However Degree Centrality and Eigenvector Centrality affect the view count negatively. From this research some strategic points for the utilizing of contents diffusion are as followings. First, it is needed to manage general factors such as the number of uploader followers or subscribers, the video age, the number of comments, average rating points, and etc. The impact of average rating points is not so much important as we thought before. However, it is needed to increase the number of uploader followers strategically and sustain the contents in the service as long as possible. Second, we need to pay attention to the impacts of betweenness centrality and closeness centrality among other network factors. Users seems to search the related subject or similar contents after watching a content. It is needed to shorten the distance between other popular contents in the service. Namely, this study showed that it is beneficial for increasing view counts by decreasing the number of search attempts and increasing similarity with many other contents. This is consistent with the result of the clustering coefficient impact analysis. Third, it is important to notice the negative impact of degree centrality and eigenvector centrality on the view count. If the number of connections with other contents is too much increased it means there are many similar contents and eventually it might distribute the view counts. Moreover, too high eigenvector centrality means that there are connections with popular contents around the content, and it might lose the view count because of the impact of the popular contents. It would be better to avoid connections with too powerful popular contents. From this study we analyzed the phenomenon and verified diffusion factors of Youtube contents by using an integrated model consisting of general factors and network structure factors. From the viewpoints of social contribution, this study might provide useful information to music or movie industry or other contents vendors for their effective contents services. This research provides basic schemes that can be applied strategically in online contents marketing. One of the limitations of this study is that this study formed a contents based network for the network structure analysis. It might be an indirect method to see the content network structure. We can use more various methods to establish direct content network. Further researches include more detailed researches like an analysis according to the types of contents or domains or characteristics of the contents or users, and etc.

Compared to the traditional format, the revised IPA is an effective method for selecting a management strategy as compared to the traditional IPA. Comparison between the traditional IPA and revised IPA with a management strategy has been, however, limited. Therefore, the difference between the traditional IPA and revised IPA was compared to select an effective management strategy in the Suncheon Bay Wetland Reserve. First of all, related papers were reviewed to select an appropriate revised IPA. It was found that Deng (2007)'s revised IPA was appropriate for quantifying service quality and a management strategy that affects the measurable satisfaction of visitors in the space. Second, the results of the traditional IPA were compared with the revised IPA in the Suncheon Bay Wetland Reserve and the management strategy of the revised IPA and the changes of management factors were discussed. It was found that some management factors deviated from the order of the quadrant "low priority for managers", "Concentrate management here", "Keep up the good work" were moved to the order of the quadrants "Concentrate management here", "low priority for managers" and "Possible overkill" in the revised IPA grid. The complexity as a management factor resulted in higher demand management than the traditional IPA, which moved from "low priority for managers" to "Concentrate management here". Management factors resulted in lower demand management than the traditional IPA moved from "Concentrate management here" to "low priority for managers"; these consisted of shade trees, exhibition exteriors, programs, and a guided tour. Also, management factors moved from "Keep up the good work" to "Possible overkill" consisted of relaxation facilities, glow of the setting sun, a hedge, and an exhibition interior. Over all, the revised IPA responded properly to changes in the measurable satisfaction of visitors to the Suncheon Bay Wetland Reserve. Therefore, a revised IPA should be provided for accurate and reliable guidelines when decision makers establish management strategies.

This study aims to verify the effect of green buffers, built as urban planning facilities on the reduction of ultra-fine particulate($PM_{2.5}$) and analyze changes in ultra-fine particles by structure, green volume and planting types of wayside green buffers, thus drawing the factors that can be used when green buffers are built to reduce ultra-fine particulate based on the results. This study selected Songpa-gu, and investigated 16 sites on 5 green buffers adjacent to two of Songpa-gu's main roads, 'Yangjaedaero' and 'Songpadaero'. This study divided all the green spaces into three different types-slope type, plain type and mounding type, and analyzed the mean green volume. As a result of measuring the concentration of $PM_{2.5}$, this study found that it was $55.5{\mu}g/m^3$ on average in winter, which was a harmful level according to the integrated environmental index provided by Seoul City, saying that levels above $50{\mu}g/m^3$ may have a harmful effect on sensitive groups of people. Particularly, the concentration of $PM_{2.5}$ was $38.6{\mu}g/m^3$ on average in spring, which exceeded the mean concentration of $PM_{2.5}$ in Seoul City in 2015. The mean concentrations of $PM_{2.5}$ in every investigation spot were $46.6{\mu}g/m^3$ for sidewalks, $45.5{\mu}g/m^3$ for green spaces and $42.9{\mu}g/m^3$ for residential areas, all of which were lower than $53.2{\mu}g/m^3$ for roads, regardless of the season. The concentration of $PM_{2.5}$ for residential areas was the lowest. In the stage of confirming the effect of green buffers, this study analyzed the correlation between the green volume of vegetation and the fluctuated rate of ultra-fine particles. As a result, it was found that the green coverage rate of trees and shrubs was related to the crown volume in every investigation spot but were mutually and complexly affected by each other. Therefore, this study judged that the greater the number of layers of shrubs that are made, the more effective it is in reducing the concentration of $PM_{2.5}$. As for seasonal characteristics, this study analyzed the correlation between the concentration of $PM_{2.5}$ for residential areas in winter and the green coverage rate of each green space type. As a result, this study found that there was a negative correlation showing that the higher the shrub green coverage rate is, the lower the concentration value becomes in all the slope-type, plain-type and mounding-type green spaces. This study confirmed that the number of tree rows and the number of shrub layers have negative correlations with the fluctuated concentration rate of $PM_{2.5}$. Especially, it was judged that the shrub green volume has greater effect than any other factor, and each green space type shows a negative correlation with the shrub coverage rate in winter.

This study was conducted to examine obese children's self-efficiency feeling and health promotion behavior in order to provide basic information on prevention of children obesity. Data were collected in June, 2001 from 349 normal weight children and 351 obese children, who were fifth or sixth graders at 14 primary schools located in Seoul, Busan, Daegu, Gwangju, Ansan, chungju, and Gumi. The data were analyzed through using Chronbach's $\alpha$, frequency analysis, $X^2-test$, ANOVA, and Pearson correlation. The results of this study can be summarized as follow. 1. The factor of children obesity was significantly different in the variables of sex, parents obesity, brother or sister obesity, father's occupation, level of living, health condition, and satisfaction level with their bodies. On the other hand, it was not significantly different in the variables of father's education level, mother's education level, mother's occupation, level of father's concern about health, and level of the children's concern about health. 2. In the case of normal weight children, dietary efficiency feeling was significantly different in the variables of level of father's concern about health and level of children's concern about health. In th case of obese children, the dietary efficiency feeling was significantly different in the variables of mother obesity, parents' education level, father's occupation, and the children's satisfaction level with their bodies. In the case of normal weight children, exercise efficiency feeling was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the exercise efficiency feeling was significantly different in the variables of grade, brother and sister obesity, parents' education level, father's occupation, and the children's satisfaction level with their bodies. In the case of normal weight children, social efficiency feeling was significantly different in the variables of brother and sister obesity, parents' education level, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the social efficiency feeling was significantly different in the variables of parents' education level, father's occupation, level of living, the children's health condition, and the children's satisfaction level with their bodies. 3. In the case of normal weight children, personal hygiene was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the personal hygiene was significantly different in the variables of parents' education level, father's occupation, mother's occupation, level of living, and level of parents' concern about health. In the case of normal weight children, dietary habit was significantly different in the variables of sex, level of parents's concern about health, and level of the children's concern about health. In the case of obese children, the dietary habit was significantly different in the variables of father's education level, mother's education level, level of living, and the children's satisfaction level with their bodies. In the case of normal weight children, exercise habit was significantly different in the variables of grade, sex, father's education level, mother's education level, and level of children's concern about health. In the case of obese children, the exercise habit was significantly different in the variables of grade, mother obesity, parents' education level, father's occupation, level of parent' concern about health, the children's health condition, and the children's satisfaction level with their bodies. In the case of normal weight children, prevention of infectious diseases was significantly different in the variables of sex, father's occupation, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the prevention of infectious diseases was significantly different in the variables of mother's education level and father's occupation. In the case of normal weight children, prevention of accident was significantly different in the variables of mother's education level, level of parents' concern about health, and level of the children's concern about health. In the case of obese children, the prevention of accident was significantly different in the variables of brother and sister obesity and mother's occupation. In the case of normal weight children, mental health was significantly different in the variables of father obesity, brother and sister obesity, parents' education level, and level of the children's concern about health. In the case of obese children, the mental health was significantly different in the variables of parents' educational level, father's occupation, mother's occupation, level of living, and the children's health condition. 4. According to the correlation between self-efficiency feeling and health promotion behavior, the higher the self-efficiency feeling was, the higher the level of health promotion behavior was. 5. The children obesity was influenced by the factors of level of living, level of parents' concern about health, the children's health condition, level of the children's concern about health, the children's satisfaction level with their bodies, dietary efficiency feeling, exercise efficiency feeling, social efficiency feeling, personal hygiene, dietary habit, exercise habit, prevention of infectious diseases, prevention of accident, and mental health. From the results of this study, it is clear that obese children's self-efficiency feeling is closely related with health promotion behavior. Therefore, it is necessary to strengthen children's self-efficiency feeling in order to make children control efficiently obesity for themselves.

It is known that low birth weight is a risk factor for poor outcome in cardiac surgery for many cardiac defects. We reviewed our recent surgical experiences on congenital heart defect (other than patent ductus arteriosus) in low birth weight babies. Material and Method: From September 1994 to February 2001, 31 consecutive infants weighing 2500 g or less underwent cardiac surgery with (OHS group n=12) or without cardiopulmonary bypass (CHS group n=19). A retrospective study was carried out to evaluate short-and intermediate-term outcome. Mean gestational age and age at operation were 36.9 weeks(range, 32.3-42weeks) and 32.1days (range, 0-87days) respectively. Mean body weight at birth and operation were 1972g (range, 1100-2500g) and 2105g (range, 1450-2500 g) respectively. There was no difference between the two groups in age and body weight. Defects included ventricular septal defect (VSD) (n=3), VSD with arch anomaly (n=2), total anomalous pulmonary venous return (n=2), transposition of the great arteries (TGA) (n=2), truncus arteriosus (n=2), and univentricular heart with cor triatriatum (n=1) in OHS group, and coarctation of aorta (n=7), tetralogy of Fallot (TOF) (n=3), TOF with pulmonary atresia (n=3), multiple muscular VSDs (n=1), double outlet right ventricle (n=1), pulmonary atresia with intact ventricular septum (n=2), tricuspid atresia (n=1), and TGA with multiple VSD (n=1) in CHS group. 13 patients (41.9%) were intubated pre-operatively. Result: There were 4 early deaths(＜30 days); 1 (8.3%) in OHS group and 3 (15.8%) in non-OHS group. All these early deaths were related to the pulmonary artery banding(PAB). There was no operative mortality in infants undergoing complete repair and palliative operations other than PAB. Delayed sternal closure was required in 3 patients. Prolonged postoperative mechanical ventilation (>7 days) was required in 7 patients(58.3%) in OHS and 7(38.8%) in CHS group. Late mortality occurred in 3 patients, two of which were non-cardiac. A patient in OHS group was documented to have neurologic sequelae. All the survivors except two are in NYHA class 1. Conclusion: Complete repair and palliative operations other than PAB can be performed in low birth weight infants with low operative mortality and an acceptable intermediate-term result. However, about a half of the patients required long-term postoperative mechanical ventilation.

Background: Apoptosis plays a crucial role in carcinogenesis, as well as in development and tissue homeostasis. Terminal deoxyribonucleotidyl transferase mediated neck end labelling (TUNEL) and in situ nick end labelling (ISEL) have been used to investigate the apoptosis in tissues. Since the introduction of the M30 monoclonal antibody to overcome drawbacks of TUNEL and ISEL, the apoptosis in various tumors, with the exception of pulmonary carcinomas, has been studied. In this study, attempts were made to examine the correlation of apoptosis in non-small cell carcinomas, using both M30 and the expression of p53 protein, with the clinicopathological factors. Material and Method: Forty five patients with surgically resected non-small cell carcinomas were included. Immunohistochemical staining with M30 and p53 monoclonal antibody were peformed, and their expressions compared with the clinicopathological features. The overall survival time and recurrence-free survival time were calculated, and the factors influencing the survival time analyzed using a univariate analysis. The effects of the expression stati of M30 and p53 on the risks of cancer related to both death and recurrence were evaluated using a multivariate analysis. Result: The p53 positive group had many more M30 positive cells than the p53 negative group (p53 positive group; $61.7{\pm}26.8$ cells vs. p53 negative group; $45.6{\pm}29.6$ cells, p=0.005) and significantly more p53 positive patients showing at least 10 positive cells (apoptotic index, $Al{\ge}1$) on M30 staining (p53 positive group; 52.4% (11/21) vs. p53 negative group 16,7% (4/24), p=0.025). In the univariate analysis, the survival times in relation to smoking (pack-year), performance status (PS) and Al showed significant differences. The multivariate analysis demonstrated the relative risk (R.R) of cancer death increased almost 7.5-fold (R.R 7.482; 95% Cl $1.886{\sim}29.678$; p=0.004) and the risk of recurrence almost 3,8-fold (R.R 3.795; 95% Cl: $1.184{\sim}12.158$; p=0.025) in the high Al (${\ge}1$) compared to the low Al (<1) group. There was no prognostic effect of p53 expression on the survival time or risk of cancer death and recurrence. Conclusion: In non-small cell lung carcinomas, M30 immunohistochemistry was an excellent method for analyzing apoptosis; the high apoptotic index could be an adverse prognostic predictive factor.

Purpose : Treatment of choice for uterine cervix cancer stage IIB is radiotherapy. We analyzed survivals, Prognostic factors, patterns of failure and complications. Materials and Methods : This is a retrospective analysis of 167 patients with stage IIB carcinoma of uterine cervix treated with curative external pelvic and high dose rate intracavitary radiotherapy at the Department of Therapeutic Radiology, Soonchunhyang University Hospital from August 1985 to August 1994. All the patients followed up from 3 to 141 months(mean 60 months) and age of patients ranged from 31 to 78 years at presentation(mean : 55 years). Results : Overall complete response rate was $84\%$. The response rate for squamous cell carcimoma and adenocarcinoma were $86\%$ and $60\%$, respectively. Overall 5-years survival rate and disease free survival rate was 62 and $59\%$, respectively Mass size and treatment response were significant Prognostic factors for survival Pathologic type and parametrial involvement were marginally significants Prognostic factors. Local failure was 43 cases, distant metastasis was 14 cases and local failure plus distant metastasis was 3 cases, and most of local failures occurred within 24 months, distant metastasis within 12 months after treatment Twenty eight($16.8\%$) patients developed late rectal and urinary complications There were tendency to increasing severity and frequency according to increased fractional dose and total(rectal and bladder) dose. Conclusions : Survival rate was significantly related to tumor size and radiotherapy response. Tumor size should be considered in the clinical s1aging. To increased survival and local control, clinical trials such as decreasing duration of radiotherapy or addition of chemotherapy is needed. To detect early recurrence, regular follow up after RT is important. Because total rectal and bladder dose affected late complications. meticulous vaginal packing is needed to optimize dose of normal tissues and to decrease late complications.
