The goal of this research is to describe relations between impressions and elements in an image (i.e. color, texture and contours). Adequate image segmentation technique to extract these elements is required. We think that a sketch and a realistic painting are examples of optimal segmented images for our purpose because brush strokes are seem to be segmented areas and realistic paintings should remain the same impression as the model. For the reason, in this paper the segmentation technique which can create realistic painting-like segmentation is exploited. It is shown that the realistic painting-like segmentation is suitable for analyzing images.

The goal of suction denture is to enhance retention of dentures by the formation of negative pressure between the denture base and the underlying tissue and sealing around the denture by the mucosa. This patient has been converted to a completely edentulous state after the extraction of residual teeth. Fabrication of suction denture was planned because it was estimated that the conventional compete would be hard to achieve retention due to the absorption of residual ridge and lack of sublingual fold. Through appropriate clinical and laboratory technique such as preliminary impression on the mandibular rest position, provisional vertical dimension determination with Centric Tray^® (Ivoclar Vivadent AG, Schaan, Liechtenstein), closed mouth definitive impression and jaw relation record using individual tray with Gnathometer M^® (Ivoclar Vivadent AG, Schaan, Liechtenstein), artificial teeth arrangement considering stability of the denture, and proper polymerization technique that minimizes polymerization shrinkage, restoring the patient with suction denture resulted in satisfaction throughout the function and asesthetics.

In clinical setting, treatment-refractoriness, medication induced tardive dyskinesia and amenorrhea in chronic schizophrenia are frequently problematic. However, there are few guideline solving these problem available to clinicians. The goal of this study was collecting clinical data on clinical effectiveness and predictors of response of switching to olanzapine. We attempted to switch to olanzapine from risperidone and clozapine in chronic 31(risperidone 17, clozapine 14) schizophrenia and schizoaffective disorder patients suffering from sustained symptoms, weekly blood monitoring, medication induced tardive dyskinesia and amenorrhea. Previous antipsychotics dosage was gradually decreased for 2 or 3weeks, at the same time olanzapine dosage was gradually increased. At baseline, after 1 week, after 2 weeks and after 4 weeks we checked Brief Psychiatric Rating Scale, Clinical Global Impression Scale, Sympson-Angus Rating Scale, Barnes Akathisia Rating Scale and followed up after 12 months. Successful switch after 4 weeks was achieved in 25 patients(clozapine 9(64.2%), risperidone 16(94.1%)). Overall, mean BPRS and CGI scores increased significantly. Successful maintenance after 12 months was achieved in 17 patients(clozapine 5(35.7%), risperidone 12(70.5%)). Overall, mean BPRS and CGI scores increased significantly too. Switching to olanzapine from other atypical antipsychotics is recommendable in chronic schizophrenia with treatment refractoriness and drug induced side effect.

In the 1960s, light art using neon or fluorescent lamp, etc and 'light and space art' appeared with kinetic art. Light art that is an extension of kinetic art tends to be digitalized art and focus on movement, while light and space art emphasizes psychological side and focuses more on phenomenal experience than movement itself. Light art generally tends to offer visual play, but light and space art offers not only visual play but also deep impression on audience's mind. In this paper, LED control method using sound and how color change influences people's mind are studied based on my works try to supplement shortcoming of light art. The main goal of my work is to make more effective and empathic interaction between audience and light in order to avoid cold and mechanical impressions that light art has. Based on its contents, this study seeks method to stimulate people's emotion, and suggests applying mentality on the color and sound interaction together to media art. In conclusion, it is believed that new model of media art is suggested through this study.

The fear of crime, discussed in the early 1960s in the United States, is a psychological response, such as anxiety or concern about crime, the potential victim of a crime. These anxiety factors lead to the burden of the individual in securing the psychological stability and indirect costs of the crime against the society. Fear of crime is not a good thing, and it is a part that needs to be adjusted so that it cannot be exaggerated and distorted by the policy together with the crime coping and resolution. This is because fear of crime has as much harm as damage caused by criminal act. Eric Pawson has argued that the popular impression of violent crime is not formed because of media reports, but by official statistics. Therefore, the police should watch and analyze news related to fear of crime to reduce the social cost of fear of crime and prepare a preemptive response policy before the people have 'fear of crime'. In this paper, we propose a deep - based news classification system that helps police cope with crimes related to crimes reported in the media efficiently and quickly and precisely. The goal is to establish a system that can quickly identify changes in security issues that are rapidly increasing by categorizing news related to crime among news articles. To construct the system, crime data was learned so that news could be classified according to the type of crime. Deep learning was applied by using Google tensor flow. In the future, it is necessary to continue research on the importance of keyword according to early detection of issues that are rapidly increasing by crime type and the power of the press, and it is also necessary to constantly supplement crime related corpus.

In modern society, there are diverse sorts of VIPs including a king and individuals. Some like a king or president are in need of professional secret services, and others become VIPs by being guarded by a bodyguard company at their own request. The former is called a public guard, and the latter is a private one. In the field of the public guard, the nation should be furnished with a guard system in consideration of political circumstances to protect VIPs. That is, the parliamentary cabinet system and presidential system call for a different guard system, and the guard system's professional features vary to some degree with political situations and cultural climate. If the ultimate goal of guard is to protect the chief of the democratic and open state in a most efficient and safe manner, it's mandatorily necessary to set up a professional and specialized guard organization to provide democratic and efficient secret services. It's desired that the domestic presidential guard division should be staffed with not only expert guards but other personnels dispatched from the military and police. In the police, guard mission is splitted among various guard and security agencies, including the National Police Agency's public security bureau or the Seoul Metropolitan Police Agency's public security division, 101 security unit, mobile police and 22 special guard division. As a chain of command is separated and it's difficult to manage such organizations effectively, the National Police Agency should be exclusively in charge of VIP guard and security. In the area of private guard, the private police system has shared national security task as a middle organization between the private police and private guard. But now its intent has gradually weakened, and its mission should be redefined. In addition, the way people look at private guard should change, and they should be well informed that it could serve to prevent possible crimes, protect them against crimes and get rid of their inconveniences. To make a good impression on people, the guard associations and businesses should put their efforts into reinforcing publicity activities, and the government, academic circles and press should team up with them as well.

Purpose: This study aimed to explore nursing students' experience with community-linked nursing education programs. Methods: This study utilized a qualitative content analysis. Participants were 55 sophomore nursing students. The community-linked nursing education program was conducted for eight weeks using the Analysis, Design, Development, Implementation, Evolution (ADDIE) model. Data were collected from 55 reflection records and five individual interviews and then analyzed through the three steps of qualitative content analysis, coding, condensing, and categorizing. Results: Twelve categories, 26 subcategories, and six topics emerged. The themes of impression and lesson from the community-linked nursing education programs were "recognizing the importance of professional competence in performing the role of nurse," "recognizing the need for leadership and cooperation in nursing practice," and "increased awareness of the role as a nursing professional for community residents." The themes of the strategies used were "looking at the goal and moving forward," and "aligning differences and working together with team/community members." The theme of strategies for the advancement of community-linked nursing education programs was "establishing a sustainable student-participating community-linked education program." Conclusion: The community-linked nursing education programs made students aware of the necessary competencies as professionals. In particular, they gave them hope for their role as professional nurses in the community. It could also be seen that they developed the ability to engage in team activities for community activities. Community-linked nursing education programs will need to be developed into continuous programs with community residents.

Background: Even though the necessity for premedication has been questioned, some combinations of antisialogogues, sedatives and analgesics are usually employed by most bronchoscopists. The goal of this study was to determine whether fiberoptic bronchoscopy(FOB) could be performed safely and effectively without premedication while using a standardized topical anesthetic. Method: Eighty outpatients were randomized in a double-blind manner into group I(n=20) with 1 ml normal saline, group II(n=20) with 0.5mg of atropine, group III(n=20) with 0.5mg of atropine plus 5mg of midazolam, and group IV(n=20) with 0.5mg of atropine plus 50mg of meperidine, given intramuscularly 30 minutes before FOB as premedication Topical anesthetics administered were same in each group. Each patient was given 5ml(200mg) of 4% nebulized lidocaine and additional intratracheobronchial 2% lidocaine. Oxygen saturation, pulse rate and electrocardiogram were monitored and recorded before, during, just after and 2 minutes after FOB. Immediately after FOB, the bronchoscopists answered four questions such as ease of procedure, extent of coughing, extent of secretion, and overall impression. Before leaving bronchoscopy suite, patients completed similar questions on discomfort during procedure, and willingness to return for a repeat procedure. Results: Age, gender, baseline pulmonary function, dose of 2% lidocaine used for topical anesthesia, and duration of FOB were not significantly different. There was no statistical difference among group I to IV with regard to extent of coughing answered by bronchoscopist. But extent of secretion was significantly different between group I without atropine and group II-IV with atropine. And there was also significant difference in ease of procedure and overall impression among groups. There was no statistical difference in patient's willingness and level of discomfort among the groups. Thirteen patients(16%) showed hypoxemia(arterial oxygen saturation: <90%), and 3 patients(4%) showed significant tachyarrhythmia(heart rate: > l60/min), but the rate of complication was not statistically different among the groups. Conclusion: These results suggest that the value of premedication is questionable for outpatient FOB, although it may be necessary in excessively anxious patient.

The Design Society of Korea. It is our urgent task that we should map out our detailed guiedlines for the improvement of export-oriented industries and of the design of export goods in preparation for our export goal of $30 billion in the upcoming 1980s. The government, university design researchers, and most entrepreneurs have confronted diverse kinds of racking issues: how much do most export industries take advantage of the indus-trial design for the improvement of the quality of export goods\ulcorner, structural defects of most export industries, chronic and vicious cycle of overlooking the value of the industrial design in the process of manufacturing export goods and etc. In other words, the recent trend of slighting the industrial design is to speed up the sales of only unsophisticated goods on the international markets. Although Koreans have been plagued by scantiness of natural resources under these circumstances, most Korean people have showed off their strong will for today's growth. Furthermore, most exporters should do their best to sweep overseas markets by manufacturing sophisticated goods outranking those commodi-ties made by the United States, Japan, West Germany and the other developed countries. In this respect, we have to make our best efforts for the expensive application and practical use of the industrial design, one of the comprehensive sciences, in the face of the hard realities and conditions which we have confronted until now. For example, it can be attributed to the practical application of the industrial design that the neighboring Japan, West Germany, France, the United Kingdom in Europe, and the United States in North America have formulated a highly advan-ced cultural zone and braced up for their own trade protection-ism and tightened their embargoes on EEC goods. Unless any export goods take the best advantage of the industrial design, one of the behavioral sciences capable of satisfying the material mental needs of modern men and of promoting cultural growth, I am convinced that they will not infiltrate into any countries that have enjoyed their own highly cultural lives. It is absolutely important that most Korean universities, state-run, private corporations and research institutes should work out the improvement strategy for the development and practical use of the industrial design as will as the revision of the present curricula of the departments of design. However, most design researchers have come to grips with several difficult problems such as the correlation of export oriented industries and the industrial design and the development of the design of export goods. The improvement of the industrial design is our urgent assignment that we have to solve in the 1980s. Accordimgly, I cannot too much emphasize the value the recognition of the industrial design in our industrial communities because we have never witnessed the prosperity of those countries which have taken little notice of the importance of the industrial design. Hopefully, most entrepreneurs will take much consideration of the value of the industrial design and then can defeat their rival businessmen on the international markets by exporting goods of highly sophisticated design. In this respect, the main purpose of the research paper which this society presented is to underline the fact that the improvement and development of the industrial design is our common assignment to be studied from the viewpoints of national dimension as well as in conformity with our immediate goal for the export-oriented prosperity of state. In conclusion, I would like to highlight the fact that our export goods shall be continually developed in pace with the correlative improvement of the indudtrial design so as to pave the way for their bright prospect and to enhance their best impression of the first-class goods on the international markets.
