The Korean animation that has relatively short history compared to the Western Europe and Japan's animation started out from the non-commercial short-piece animation produced as part of advertisement animation and culture movie in the later part of 1950s. In 1960s, the culture movie animation reflecting for the Movie Act and cultural policies has hardly been mentioned in the history of Korean animation, but they are the precious cultural work produced prior to the theatrical long-piece animation. In particular, compared to the 15-second short CF animation, the short-piece animations are ranging for 4 minutes to 10 minutes as the work pieces with the historic value to measure the level of the Korean animation at that time. in 1960s, approximately 20 short-piece animation works were produced and they contained the educational contents to enlighten general public in the process of modernization policy. Those short-piece animations produced in cultural movie at the National Film Production Center of Korea had been produced not only in cell-facilitating cartoon animation, but also in paper animation and puppet animation. In this background, this thesis takes a close look to the short-piece animation works produced in the National Film Production Center of Korea in 1960s. While there was almost no studies of early short-piece animation other than CF works, it is meaningful to discover and analyze the works, and, Director Park Young-il, Director Han Sung-hak, Director Jung Do-bin, Director Shin Dong-hyun, Director Nelson Shin and others participated in the creative work process have worked as the animation directors for theater that the analysis on the works would be considered as important fundamental studies to understand the Korean animation. Under this thesis, it is intended to study the historic implication and formative characteristics around some 10 work pieces to affirm participating personnel, including directors, for the short-piece animation created by the National Film Production Center of Korea as well as the situation of time to launch the National Film Production Center of Korea in 1960s. Through this effort, it is intended to come up with the starting point to process enriched researches on non-commercial short-piece animation as well as contemplation on the Korean animation history that have been neglected in the study of the Korean animation history through such effort.

Purpose : This study was performed to follow the natural course and size change of isolated atrial septal defect(ASD) secundum. Methods : Among the newly diagnosed with ASD secundum at the division of pediatric cardiology in Yonsei cardiovascular hospital from January 1996 to December 2000, 89 patients with pure ASD secundum were checked by the serial echocardiographic evaluation to measure the size change. Results : There was a statistical difference(P<0.05) in the rate of spontaneous closure and size change of the defect between the group of bigger defect(>8 mm) and the group of smaller defect (${\leq}8mm$). There was also a statistical difference(P<0.05) in the rate of spontaneous closure and size change of the defect between the group of younger than three years of age and the group of older than three years of age. The initial size of the defect and change of size were the significant influencing factors in the rate of spontaneous closing of ASD. In the group of patients who have persistent ASD, the size of defect showed a tendency of increasing size of defect with the age(P<0.005); however in the correction of these values by the body surface area of each patients, there was no statistical difference. Conclusion : The possibility of spontaneous closure of pure ASD secundum was higher in the group of patients who have smaller defect and who were younger. The ASD secundum that did not have spontaneous closure showed an increase in size with the growth of the patients; however when this size was corrected by the body surface area, there was no statistical difference. The closure of the defect was at 26.2 months of age so close follow-up of the patients is important.

Purpose: The goal of this study is to find out how useful ultrasonography is in measuring amount of effusion within the knee joint in comparison with physical examination and simple radiography. Materials and Methods: We evaluated total 60 cases which were suspicious for joint effusion. Average age was 61.3 years. The group was consisted of 22 males and 38 females, and 24 obese people and 36 non-obese people. Stroke test and patella floating test were done as physical examination. Amount of joint effusion was classified into 3 groups in simple lateral radiographic view and ultrasonography was used for recheck-up. Results: 39 cases were found positive in stroke test, and patella floating was shown in 20 cases. In simple lateral radiographic view, 47 cases of grade I, 7 cases of grade II and 3 cases of grade III were checked. Average $7.67{\pm}2.90mm$ amount of effusion was checked by ultrasonography. Amount of fluid in stroke test, patella floating test and simple lateral radiographic view showed close correlation with ultrasonography. Gender did not seem to affect physical examination, but strong correlation was found in female in simple radiography. Obese group showed closer relationship with all 3 exams compared with non-obese group. Physical examination was relatively effective with nonobese group, but not with obese group. And it was not easy to measure the amount of fluid with simple radiographic view, but we could obtain objective data from ultrasonography by measuring the amount of effusion dynamically. Conclusion: We concluded that more objective data was obtained with ultrasonography in comparison with physical examinations and simple radiography in the aspect of measuring amount of joint fluid.

The purpose of this study is to empirically analyze how social comparative learning of forum participants affects learning effects with an emphasis on participants' characteristics. As today's society is changing at a fast pace, the desire for new knowledge and information has grown accordingly. To quench this thirst for knowledge and information, seminars, symposiums, conferences, forums, conventions, exhibitions, and more are taking place as part of knowledge sharing events across the world. Also, the increased need for knowledge and information exchange has led the development and growth of the convention industry and Meetings, Incentives, Conferences, and Events (Exhibitions)(MICE) industry. Especially, forum is a type of event which invites professionals and specialists to discuss diverse topics and share their knowledge and experience with the audience. The participants utilize it as an opportunity to get close to information providers and enjoy the pleasure of knowledge exchange. However, there have been few empirical analyses on who the participants are, why they attend forum, how they pick up and learn new information and knowledge, and what kinds of learning effects they achieve after the event. This paper is to analyze how social comparative learning of the forum's participants influences learning effects based on Albert Bandura's Social Learning Theory (1977, 1997, 1982. 2001) and Leon Festinger's Social Comparative Theory (1950, 1954). By dividing the participants into two groups, one with high level of self-efficacy and the other with low level of self-efficacy, we have examined the differences in learning effects between the two groups using them as moderating variables. This study was conducted in 'MBN Y Forum 2016,' which is one of the most representative knowledge exchange forums of South Korea. An online survey was distributed out and, 1,307(39.2%) out of the total participants of 3,338 have completed the survey. The survey included questions about whether the participants have gained positive or negative motivations by comparing themselves to the speakers (upward comparison learning) and other participants (lateral comparison learning). The results have shown the quality of messages that the speakers are presenting as knowledge providers is the most significant factor that acts on learning effects. Particularly, the participants had higher levels of self-efficacy and self-esteem than average people. They had a clear goal to learn from the speakers (upward comparison) and received positive motivations from them. In other words, no negative learning effects had been found. This presents a managerial implication that having a qualified speaker is necessary for a forum to be successful. On the other hand, the results from the comparison with the other participants (lateral comparison) were different. The participants were likely to compare themselves to the other participants through observational learning. They could compare listening attitudes, language skills, or capabilities to ask a question. The results have showed the participants received positive motivations from the lateral group but at the same time were jealous of abilities of the others. When the quality of a question by a participant is not good enough, it can have a negative influence on the participants' learning effects. The first group with high levels of self-efficacy and self-esteem had no correlation to negative learning effects from the speakers. They rather had a strong desire to learn from the speakers. On the contrary, the participants perceived the lateral group as a learning subset and competitor. The second group with low levels of self-efficacy and self-esteem saw the quasi-group as a rival. This presents that the individual learning effects can be different depending on the participants' characteristics.

In the early days of the Goryeo Dynasty, the royal guard was comprised of the central regular army in the 2-gun-6-wi system, and Nasungeomgun was in charge of the security inside the palace. However, the military system became disorganized during the period of military rule and the royal guard had to rely on military subjects. The military officials suppressed the civil ministers centering on Jungbang, the guarding organization close to the King to incapacitate the royal authority and control the state affairs. When the rule of the three leaders of the military rule became short-lived and Dae-seung Gyeong is raised to the ruler, he organized a do-or-die squad comprised of a hundred and more people for his personal safety, and this became the first dobang. Dobang was disassembled after Dae-seung Gyeong died of disease, but under the rule of Chung-heon Choe, Dae-seung Gyeong's dobang was revived and reinforced into 'Yukbeon Dobang' to provide the ruler with personal protection and intensify the ruling system, and it was quite a large organization with more refined system. Yukbeon Dobang was expanded and reinforced into Naeoedobang under the rule of Woo Choe, the son of Chung-heon Choe, and it was enhanced even more into Dobang Samsipyukbeon System under the rule of the grandson, Hang Choe. Dobang can be considered as the guard organization in modern sense, and it collected information and surveyed the area where guarding is required and house troops that belonged to Naedobang eliminated the risks that may follow afterwards to make assurance doubly sure for guarding. The Choe's regime established Mabyeolcho as a private guard organization in addition to dobang, and this formed the cavalry and infantry units with dobang. Yabyeolcho organized by Woo Choe in the reign of King Gojong was divided into Joabyeolcho and Ubyeolcho, and later Sineuigun was integrated with them to form Sambyeolcho. Originally, Yabyeolcho was established under the rule of Woo Choe to prevent crime in the evening, but after Sineuigun was organized with the ones who were captured by Mongolian army but escaped, in other words when Sambyeolcho was organized, the organization displayed much broader influence by covering military and police affairs as well as punishment and imprisonment. The guarding organization during the Period of Military Rule in the Goryeo Dynasty did not have strict distinction between official guard and personal guard. The private guard in modern days which is the equivalent of personal guard is characterized by its commerciality, however, house troops and the members of dobang did not seem to pursued profit. The guard organization during the period of military rule started from dobang which was organized for personal safety but gradually developed publicness through the participation of civil ministers and expansion, and later it played the pivotal role for social security serving official purpose up to the level where the distinction between official and private activities was blurred during the period of Sambyeolcho.

Purpose : To discuss the technical aspect of interstitial brachytherapy including method of implant, insertion time of radioactive source, total radiation dose, and complication, we reviewed patients who had diagnoses of soft tissue sarcoma and were treated by conservative surgery, interstitial implant and external beam radiation therapy Materials and Methods : Between May 1995 and Dec. 1997, ten patients with primary or recurrent soft tissue sarcoma underwent surgical resection (wide margin excision) and received radiotherapy including interstitial brachytherapy. Catheters were placed with regular intervals of 1 ~l.5 cm immediately after tumor removal and covering the critical structures, such as neurovascular bundle or bone, with gelform, muscle, or tissue expander in the cases where the tumors were close to those structures. Brachytherapy consisted of high dose rate, iridium-192 implant which delivered 12~15 Gy to 1 cm distance from the center of source axis with 2~2.5 Gy/fraction, twice a day, starting on 6th day after the surgery, Within one month after the surgery, total dose of 50~55 Gy was delivered to the tumor bed with wide margin by the external beam radiotherapy. Results : All patients completed planned interstitial brachytherapy without acute side effects directly related with catheter implantation such as infection or bleeding. With median follow up duration of 25 months (range 12~41 months), no local recurrences were observed. And there was no severe form of chronic complication (RTOGIEORTC grade 3 or 4). Conclusion : The high dose rate interstitial brachytherapy is easy and safe way to minimize the radiation dose delivered to the adjacent normal tissue and to decrease radiation induced chronic morbidity such as fibrosis by reducing the total dose of external radiotherapy in the management of soft tissue sarcoma with conservative surgery.

Objective: When an alveolar cleft is too large to close with adjacent mucobuccal flaps or large secondary fistula following a primary bilateral palatoplasty exists, a one-stage procedure for bone grafting becomes challenging. In such a case, we used the tongue flap to repair the fistula and cleft alveolus in the first stage, and bone grafting to the cleft defect was performed in the second stage several months later. The purpose of this paper is to report our experiences with the use of an anteriorly-based Y-shaped tongue flap to fit the palatal and labial alveolar defects and the ultimate result of the bone graft. Patients: A series of 14 patients underwent surgery of this type from January 1994 to December 1998.The average age of the patients was 15.8 years old (range: 5 to 28 years old). The mean period of follow-up following the 2nd stage bone raft operation was 45.9 months (range: 9 to 68 months). In nine of the 14 cases, the long-fork type of a Yshaped tongue flap was used for extended coverage of the labial side alveolar defects with the palatal fistula in the remaining cases the short-forked design was used. Results: All cases demonstrated a good clinical result after the initial repair of cleft alveolus and palatal fistula. There was no fistula recurrence, although Partial necrosis of distal margin in long-forked tongue flap was occurred in one case. Furthermore, the bone graft, which was performed an average of 8 months after the tongue flap repair, was always successful. Occasionally, the transferred tongue tissue was bulging and interfering with the hygienic care of nearby teeth; however, these problems were able to be solved with proper contour-pasty performed afterwards. No donor site complications such as sensory disturbance, change in taste, limitations in tongue movement, normal speech impairments or tongue disfigurement were encountered. Conclusion: This two-stage reconstruction of a bilateral cleft alveolus using a Y-shaped tongue flap and iliac bone graft was very successful. It may be indicated for a bilateral cleft alveolus patient where the direct closure of the cleft defect with adjacent tissue or the buccal flap is not easy due to scarred fibrotic mucosa and/or accompanied residual palatal fistula.

Helicopter-borne aeromagnetic surveys at two different times separated by three years were conducted to better understand the shallow subsurface structure of the Vulcano and Lipari volcanic complex, Aeolian Islands, southern Italy, and also to monitor the volcanic activity of the area. As there was no meaningful difference between the two magnetic datasets to imply an apparent change of the volcanic activity, the datasets were merged to produce an aeromagnetic map with wider coverage than was given by a single dataset. Apparent magnetisation intensity mapping was applied to terrain-corrected magnetic anomalies, and showed local magnetisation highs in and around Fossa Cone, suggesting heterogeneity of the cone. Magnetic modelling was conducted for three of those magnetisation highs. Each model implied the presence of concealed volcanic products overlain by pyroclastic rocks from the Fossa crater. The model for the Fossa crater area suggests a buried trachytic lava flow on the southern edge of the present crater. The magnetic model at Forgia Vecchia suggests that phreatic cones can be interpreted as resulting from a concealed eruptive centre, with thick latitic lavas that fill up Fossa Caldera. However, the distribution of lavas seems to be limited to a smaller area than was expected from drilling results. This can be explained partly by alteration of the lavas by intense hydrothermal activity, as seen at geothermal areas close to Porto Levante. The magnetic model at the north-eastern Fossa Cone implies that thick lavas accumulated as another eruption centre in the early stage of the activity of Fossa. Recent geoelectric surveys showed high-resistivity zones in the areas of the last two magnetic models.

This study was to offer a basic data for setting up new curriculum and preparing for effective instruction and education methode on md and nutrition section by researching & analyzing the degree of necessity, difficulty and utilization in actual life of food and nutrition section which requires a close relation with actual life and home economics for the second grade students who studied home economics in the first grade in a middle school. The results obtained were as follows. A highest number of students$(38.9\%)$ responded that 'they learned skills required in home life such as cooking, laundry and childcare' on a question of home economics recognition and the next highest percentage of students$(27.5\%)$ responded' they learned of healthy life and correct human building through home economics education'. For the recognition of a food and nutrition section the highest percentage of students$(38.8\%)$ responded that 'they learned the knowledge and principle of food nutrition for the improvement of a food and nutrition', and the next highest percentage of students$(30.7\%)$ responded 'they teamed practical skills required in actual life'. The meal and nutrition of juvenile, and the principle and practice of cooking was highly ranked in order for the necessity on the food and nutrition section, girl students accounting for higher percentage than boys in overall food and nutrition section and all areas. A nutrition of juvenile, a meal of juvenile, and the principle of cooking and cooking practice was middle ranked in order for the difficulty of the food and nutrition section. Girl students recognized overall food and nutrition section more difficult and also they recognized a nutrition of juvenile and a meal of juvenile more difficult than boy students, but boy students recognized the principle of cooking and cooking practice more difficult than girls. On the practical use of the food and nutrition section in actual life, a meal of juvenile, the principle of cooking and cooking practice, nutrition of juvenile was low ranked in order. Boy students practically used overall food and nutrition section including a meal of juvenile and nutrition of juvenile in detail with high percentage, and girl students practically used the principle of cooking and cooking practice with high percentage. . Regarding interrelation of the degree of necessity, difficultly and utilization on food and nutrition section, as the degree of necessity was high on food and nutrition, the degree of practice was high in all the areas, and as respondents recognized food and nutrition section difficult, they practically used a food and nutrition section at low percentage.

This paper regards former Samsung lawyer Kim Yong-Chul's action of claiming Samsung Group's slush fund as typical Whistle-Blowing from inside. News frames in KBS, SBS TV were examined through comparative analysis. In formal feature, 'episodic news frame' hold an absolute majority in both stations. From news sources, the group of whistle-blower such as lawyer Kim Yong-Chul and civic groups was confronted with Samsung and state authorities including the Prosecutor, financial agencies. Analysis on the theme of news coverages demonstrated 5 frames: 'public announcing frame', 'news of conflict frame' 'demanding a close inquiry frame', 'declaration of conscience frame', 'causing social upheaval frame', Analysis result shows that 'public announcing frame' was most frequently used in reporting and there was distinction between KBS and SBS in 'declaration of conscience frame' and 'causing social upheaval frame'. Relatively KBS preferred 'declaration of conscience frame' and SBS would use 'causing social upheaval frame', from which reciprocal relation as media ownership could be analogized. Both media tend to make light of in-depth news coverages on structural issues or essential settlement and it is shown that both stations treated this situation with intriguing audiences as stressing sensitive parts in this event. Follow-up of changing process of 'declaration of conscience frame' through diachronic analysis on framing informs that additional exposure of 'Lee Yong Chul', former secretary in Nov 19, 2007 influenced increasing of frequency of using 'declaration of conscience frame'. However, news reporting on whistle-blower in KBS and SBS generally adheres to passive attitude of following changes in the surroundings rather than playing an active role in improving social recognition on whistle-blowing, which can induce to the spread of negative feature on it. Thus it is assumed that terrestial television broadcasting should regard whistle-blowing as contradiction in social structures and active depth reporting seems to be neded for improving social recognition on whistle-blowing.
