  • The automotive industry is undergoing a paradigm shift due to the convergence of IT and rapid digital transformation. Various components, including embedded structures and systems with complex architectures that incorporate IC semiconductors, are being integrated and modularized. As a result, there has been a significant increase in vehicle defects, raising expectations for the quality of automotive parts. As more and more data is being accumulated, there is an active effort to go beyond traditional reliability analysis methods and apply machine learning models based on the accumulated big data. However, there are still not many cases where machine learning is used in product development to identify factors of defects in performance and durability of products and incorporate feedback into the design to improve product quality. In this paper, we applied a prediction algorithm to the defects of automotive door devices equipped with automatic responsive sensors, which are commonly installed in recent electric and hydrogen vehicles. To do so, we selected test items, built a measurement emulation system for data acquisition, and conducted comparative evaluations by applying different machine learning algorithms to the measured data. The results in terms of R2 score were as follows: Ordinary multiple regression 0.96, Ridge regression 0.95, Lasso regression 0.89, Elastic regression 0.91.

  • The movement of characters is one of the crucial elements to deliver their emotion flowing inside. Though it is the same movement, it may appear or be expressed differently according to the character's personality or emotion or the particular situation. The purpose of this study is to analyze not only the movement found superficially in an animation but also a character's internal emotion and attitude with Laban's movement analysis system, particularly effort, one of its analysis categories, and examine how effectively Laban's movement analysis often employed at the circles of dance can analyze movement in an animation. is about a monster that constantly makes efforts to realize its dream to be a scarer. Functional movement forms the most part, but expressive movement to show how a character thinks or feels also appears harmoniously. Characters' externally shown movement can express their internal emotion properly sometimes, but they also often move expressing their feelings in moderation. Therefore, this study analyzes the movement of characters found in the four scenes of with LMA's effort. According to the findings, at the scene where Michael enters the door leading to the human world following the scarer, the emotional state of Michael envious of the scarer is expressed with the Vision Drive giving the strong feel of dreaming. At the scene of the second game to choose the best scare team, it shows us the Spell Drive with its careful and light movement having clear intention to survive at the game. At the scene where there is a party held for the teams that have survived, it shows the Passion Drive of being eagerly expressing happy and delightful feelings without considering what is around. At the scene where Michael and Sullivan are pursued by people, the Action Drive was used to express movement that was heavy and strong and was getting faster gradually by focusing the feelings of the characters in haste into one place.

  • During the period from 2001 to 2005, 29,892 burglaries took place in Korea with the approximate average annual number - 5,978 cases. This study was conducted to analyze the reported burglaries and the result was summarized as follows. There were 8,605 residential invasion burglaries (28.8%) as the most frequent characteristic pattern. The exit was used as the most frequent invasion route for 4,031 invasion burglaries (64.3%), and an unlocked exit door or window was used as the most frequent invasion method for 2,462 invasion burglaries (28.6%). The hours just after midnight (between 00:00 and 04:00) were the most frequent time for invasion burglary to occur. Also, 5,652 burglaries occurred on Wednesday which was twice higher than on Sunday (2,988 burglaries). It was shown that the number of persons injured during burglaries were 260 deaths and 10,610 injuries. The places of the highest occurrence were the street with 10,183 burglaries (34%) and then residential place with 7,527 burglaries (approximately 25%). One-man burglary was the highest complicity: 15,012 offenders (56.1%). The knife was used as the most frequent instrument for 6,498 burglaries (24,3%) what is rare, while no criminal tool or instrument was used for 15,631 burglaries (58.4). During the period from 2001 to 2006, 1,506 burglaries occurred in Daegu and the average annual number was 251 burglaries. Among those,515 residential invasion burglaries (34.2%) took place and the average annual number was approximately 86 cases. The hours just after midnight (between 00:00 and 04:00) were the most frequent time for invasion burglary to occur (194 cases, 37.7%), the place of the highest invasion occurrence was the residential place (259 cases, 50.3%), and the exit was used as the most frequent invasion route (87 cases, 37.7%). An unlocked exit door or window was the most frequent invasion method (65 cases, 25.1%). In addition, pretending to be a delivery man, visitor or following the victim methods were used for 26 burglaries (10%). It is apparent that personal preventive measures against crimes, as well as governmental and social measures, play an important role in preventing burglaries. In particular, based on the analyzed result that an unlocked window or exit door was most frequently used for reported burglaries, it seems that there is a lack of understanding of crime prevention while little effort has been made to prevent crimes. Although everyone knows that locking a door is one of the basic measures to prevent crimes, many people tend to pay little attention to lock a door properly so burglary takes place. This study, therefore, is intended to encourage people to pay more careful attention to crime prevention, in order to help reduce the probability of burglary. With the recent improvement in social understanding of scientific crime investigation, a wide variety of police professions, including crime analysts, crime victim police counselors and coroners, have been prepared to develop the scientific crime investigation and crime analysis. In addition, it is hoped that further this study will contribute to encourage studies on crime prevention to be carried out in the future.

  • Planar antennas are very efficient for the use of the out-door data transmission applications due to their low-profile characteristics. But the size of the antenna in UHF band blocks the practical usage. In this paper, a miniaturized planar antenna is investigated for the application of AMR system in UHF band. The designed antenna is fabricated in the form of the microstrip patch on the FR-4 substrate. The miniaturization is achieved by slot-loading on the patch. First, effects of simple slots on the size reduction are analyzed, followed by the design using more complex slots resulting in the reduction ratio of 37.9% in 425.6 MHz and bandwidth of 3.8 MHz. The effort of epoxy coating for the protection is also investigated.

  • This study analyzed the changes of welfare and labor market status of participants of Self-sufficiency Support Program in Korea thorough of analysis follow-up data which were collected about the experiences and changes of participants of the program in Gyeonggi province in 2005. As the results, many of participants exited from the program within five years, and hardly anyone depends on the welfare or the program, also there is very little the revolving door phenomenon. Whatever, the program have positive effects the changes of welfare and labor market status of them. Also, self-sufficiency communities, the small enterprises are started by more two participants and aim the economic independence of them and contribution to social economy have played important role for their persistent work and economic self-reliance. The people exited from the program, however, hardly succeed in exit from the welfare and their economic conditions still are not good. Therefore, we have to arrange the program for the participants' self-sufficiency, and we rather have to effort to secure their economic well-being than emphasize the immediately employment or establishment a business.

  • Purpose : Computed tomographic equipment is essential for diagnosis by means of radiation. With passage of time and development of science computed tomographic was developed time and again and in future examination by means of this equipment is expected to increase. In this connection these authors measured rate of scatter ray generation at front of lead glass for patients within control room of computed tomographic equipment room and outside of entrance door for exit and entrance of patients and attempted to ind out method for minimizing exposure to scatter ray. Material and Method : From November 2001 twenty five units of computed tomographic equipments which were already installed and operation by 13 general hospitals and university hospitals in Seoul were subjected to this study. As condition of photographing those recommended by manufacturer for measuring exposure to sauter ray was use. At the time objects used DALI CT Radiation Dose Test Phantom fot Head (${\oint}16\;cm$ Plexglas) and Phantom for Stomache(${\oint}32\;cm$ Plexglas) were used. For measurement of scatter ray Reader (Radiation Monitor Controller Model 2026) and G-M Survey were used to Survey Meter of Radical Corporation, model $20{\times}5-1800$, Electrometer/Ion Chamber, S/N 21740. Spots for measurement of scatter ray included front of lead glass for patients within control room of computed tomographic equipment room which is place where most of work by gradiographic personnel are carried out and is outside of entrance door for exit and entrance of patients and their guardians and at spot 100 cm off from isocenter at the time of scanning the object. The results : Work environment within computed tomography room which was installed and under operation by each hospital showed considerable difference depending on circumstances of pertinent hospitals and status of scatter ray was as follows. 1) From isocenter of computed tomographic equipment to lead glass for patients within control room average distance was 377 cm. At that time scatter ray showed diverse distribution from spot where no presence was detected to spot where about 100 mR/week was detected. But it met requirement of weekly tolerance $2.58{\times}10^{-5}\;C/kg$(100 mR/week). 2) From isocenter of computed tomographic equipment to outside of entrance door where patients and their guardians exit and enter was 439 cm in average, At that time scatter ray showed diverse distribution from spot where almost no presence was detected to spot with different level but in most of cases it satisfied requirement of weekly tolerance of $2.58{\times}10^{-6}\;C/kg$(100 mR/week). 3) At the time of scanning object amount of scatter ray at spot with 100 cm distance from isocenter showed considerable difference depending on equipments. Conclusion : Use of computed tomographic equipment as one for generation of radiation for diagnosis is increasing daily. Compared to other general X-ray photographing field of diagnosis is very high but there is a high possibility of exposure to radiation and scatter ray. To be free from scatter ray at computed tomographic equipment room even by slight degree it is essential to secure sufficient space and more effort should be exerted for development of variety of skills to enable maximum photographic image at minimum cost.

  • At the beginning of the modern times, orientalism and ethnic character was the main stream of current fashion. Early in the twentieth century, orientalism had a tremendous affect on various areas of society, culture, and art. Particularly, it inspired and activated the design of costume. A great variety of colors and construction of the Orient and geometrical simplicity were based on the creation of modern costume. Ethnic placed weight on the Orient because Japan strengthened competitiveness and China opened the door to foreign countries. Therefore, a large number of the oriental costume produced by a variety of fashion designers. The oriental handicraft, motif and colors of the traditional costume have been used in modern costume. In addition, they are precious ideas for designers. This thesis is about a Study on costume embroidery close to fashion through the oriental embroidery and the concept of oriental embroidery. It is also a study on patterns, skills and colors of the oriental embroidery shown in modern fashion and practical use through the designers works. First, concept, process of change, patterns, skills and colors of the oriental embroidery are mainly discussed. 1.The oriental embroidery consists of life, Buddhism, appreciation and costume embroidery. Embroidery was widely used for a variety of purposes. First, it is to make a good impression and beauty. Second, to decorate many kinds of patterns and shapes. Last, to indicate social status and stages. 2.The origin of the oriental embroidery started in Persia. was It greatly developed in Iran and was introduced in Korea via China. We are reminded of the oriental embroidery of China. China is the original place of oriental embroidery. Oriental embroidery has developed the peculiar embroidery according to each climate, custom and nationality. On the basis of these, the practical use of the oriental embroidery on modern fashion is presented through patterns, skills and colors which leads Korean designers use. Even though the oriental embroidery is not very popular among people owing to a great deal of cost and a demand for labor, the patterns and colors of the embroidery has been already familiar with the contemporaries A more profound study on the oriental embroidery will supply a great deal of material and ideas to the fashion industry. Moreover, an effort to raise self-pride in traditional culture will be also in need.

  • Verdicts related to major medical litigation given by the Seoul Central District Court, the Seoul High Court and the Supreme Court in 2010 were analyzed. It's shown that in cases of the medical negligence regarding the occurrence of neonatal cerebral palsy, the plaintiff claims were dismissed using criteria proposed by associations of Obstetrics and Gynecology and Pediatrics in US, and thereof the burden of plaintiffs to prove the medical negligence has increased. In addition, in case of that the expected survival period of infants gets longer, payments for treatment and nursing after survival period determined by judges are made and it was judged to compensate it as a periodical indemnity. In case for the explanation obligation the most frequently mentioned in the medical litigation, in addition to cases of invoking the existing theory of explanation obligation, verdicts to mention the instructions of theory regarding instruction explanation obligation and the possibility of compensation for damages on property are given. Particularly, in cases for a liability of reparation by exaggerating the effects and not disclosing the risks related to treatment with stem cells, even if the treatment not approved by Food and Drug Administration is in violation of the Pharmaceutical Affairs Law, it's not illegal as violation in Pharmaceutical Affairs Law itself. But there is a certain verdict to present the possibility of an extension of the theory of explanation obligation by acknowledging the liability of reparation caused by illegal acts with no explanations of effects and risks of treatment with stem cell by doctors and pharmaceutical companies. In an incident in which a mental patient fell and died through the opened door of the roof at the hospital, a liability of reparation was acknowledged due to defects in structure installation management and this verdict drew an attention since the overall management responsibility about patients including structures was acknowledged to the hospital besides the obligations on medical practice. In case of the verdict without giving the opportunity to state the opinion with respect to the main legal issues, the responsibility of the court was emphasized since the court did not fulfill the explanation obligations. There were some cases in which payments for nursing and caring to a patient in vegetative state during the plastic surgery was admitted. However, in dental-related incidents, the proportion of cases in which plaintiff won was low since the difficulty of proving may be reflected. In the area of administrative litigation, unlike the existing position regarding arbitrary medical charge cover collected from patients in hospital, the verdict to admit the legitimacy of collection of medical treatment was given and attracted the attention of people. Verdict in which the expression related to medical advertisement was not exaggerated disposed the original verdict and pointed out the problem of excessive regulations on medical advertisement. The effort to analyze the trend of verdicts of court through reviewing the decisions and to organize should be continued, but the full decision should be disclosed as a base, and people and systems to enable the all time monitoring should be prepared.

  • Considering that rural village had evolved through a long-sustained effort of harmnization with nature, there should be the wisdom not only to reflect the level of rural resident's housing demand, but also to conserve the traditional characteristics of high-valuation in the modern rural housing. In Korea , standard design proposals of rural houses had been made public three times ; in 1972 , 1984 and 1995. so , firstly, this study analysed the inner-space layouts of design proposals mentioned above, from which changes and problems in the past housing design were derived. And also, through, the positive acceptance of residents' opinion living inthe houses built by standard design proposals in 1970 ~1980's, improved design principles and an alternative model were proposed , finally. The inner-space structed of standard design proposals in 1970s was originated from small-scaled and low-priced one, basically under the " open system". In 1980s, the basic design principle changed to the 'closed system' in which the living room being the focus of indoor family life, and , in 1990s, progressively, therural housing developed to the high qualified type by the spatial enlargement and with increased equipements. However, this structural change of rural house brought about the problem of functional separatioon between farming and daily living activities. In details, limited spaces of multipurpose spaces and sanitary facility would be mentioned as problems for improvement. conclusively in this study, newoly arranged "open system" was recommended , as a basic design principle for theinner space structure formation of rural house, which easily links the constituent inner-house spaces to outer one. Based on this principle, the detailed design criterial was proposed as follows ; 1. The living room be directly linked to the front-yard and centrally placed, the addtional space of which could be secured for the special family events by the flexibleuse of its adjacent room or by the housing of male quarters(separated from main building quarter). 2. The kitchen also be directly linked to side-yard and to livng room , for the convenience of farming activities and the shortening of path flow housewife. 3. The expanded toilet-and-bathroom be placed in the directly connected left-hand side to the living room and also be allowed access through multipurpose spaces to out door. 4. The multipurpose spaces be directly connected to the kitchen and the toilet and-bathroom , of which function would be for undressing of working clothes, quickwashing and ordinary working.nd ordinary working.
