The purpose of this study is to analyze the effects of the BSCs of 642 firms excluding the financial and insurance companies listed on KOSPI. The analysis of financial performance through analysis of major financial ratios between BSC and non-BSC firms is compared with the input of human and material resources for business growth. We will promote the spread of BSC and examine the areas differentiated performance improvement. The analytical categories are manufacturing, service, wholesale and retail, and information and communications, which are 2,136 business years out of 2,378 final analytical samples. The results of the analysis are as follows. As a result of the analysis, among the four industries analyzed, the industries that showed the best performance were manufacturing. In the case of service industry, growth and activity were lower than those of non-adoption (NA) companies, but the operating margin was significantly different from manufacturing. However, market value was higher than that of NA companies, and R&D expenditures and advertising expenses were significantly higher than NA firms. On the other hand, there was no significant difference in profitability between the BSC and NA firms, but the market value was very significant. EPS is 5.22 times, BPS is 5.64 times, PBR is 1.3 times, and EVA is 35 times higher. In addition, R&D expenditure and advertising expenditure are more than twice as high as those of NA. In the case of the service industry, there is no significant difference in the growth performance from the NA firms. Activity indicators, BSC introduced companies are three times lower than both the total assets turnover and the capital turnover rate. The operating profit margin was high at 45.8% for introduced companies and 37.2% for non-introduced companies. In market value analysis, only BPS was 1.68 times higher. On the other hand, investment in welfare expenses is 0.2% of total assets, which is relatively low compared to NA firms. However, research and development expenses and advertising expenses are 2.1% and 1.02% of total assets, respectively, but they are relatively lower than those of NA firms. Unlike the manufacturing and service industries, wholesale and retail trade was significantly higher than the NA firms in terms of sales growth and total assets growth rate. In terms of market value, EPS and BPS were significantly higher, but the benefits, R&D expenditures, and advertising expenses were lower than those of NA firms. The information and communication industry showed lower level of performance than the NA firms in all indicators except cash liquidity, BPS, and EVA.

Since spatio-temporal local features for video representation have become an important issue of modeless bottom-up approaches in action recognition, various methods for feature extraction and description have been proposed in many papers. In particular, BoF(bag of features) has been promised coherent recognition results. The most important part for BoF is how to represent dynamic information of actions in videos. Most of existing BoF methods consider the video as a spatio-temporal volume and describe neighboring 3D interest points as complex volumetric patches. To simplify these complex 3D methods, this paper proposes a novel method that builds BoF representation as a way to learn 2D interest points directly from video data. The basic idea of proposed method is to gather feature points not only from 2D xy spatial planes of traditional frames, but from the 2D time axis called spatio-temporal frame as well. Such spatial-temporal features are able to capture dynamic information from the action videos and are well-suited to recognize human actions without need of 3D extensions for the feature descriptors. The spatio-temporal BoF approach using SIFT and SURF feature descriptors obtains good recognition rates on a well-known actions recognition dataset. Compared with more sophisticated scheme of 3D based HoG/HoF descriptors, proposed method is easier to compute and simpler to understand.

The study verified the work capacity (job performance, perception, knowledge) and satisfaction on managing the inventory of operating room nurses working in a more than 700-bed hospital. The purpose of this study was to provide basic data of education for work capacity and satisfaction and quality insurance by analyzing the scores between the three different operating rooms and the correlation between the work capacity and satisfaction by investigating the related factors. This study presented a structured and self-administered questionnaire to 181 nurses who had been working in the operating room more than six months. The mean and standard deviation of the job performance, perception, knowledge, and satisfaction were 4.2(${\pm}0.56$), 3.4(${\pm}0.76$), 3.5(${\pm}0.40$), and 3.4(${\pm}0.55$), respectively. The work capacity and satisfaction of each group did not show a statistically significant difference. The correlations between the job performance and knowledge, knowledge and perception, perception and satisfaction were positive (r=.627, p<0.01), (r=.663, p<0.01) and (r=.485, p<0.01), respectively. Among the factors related to the general characteristics of operating room nurses, only age significantly affected their job performance. This study provides basic data on the maintenance and improvement of their competence and satisfaction by being served as a resource for sustainable human resources management and training, and efficient management of the communication channel between hospitals.

Endometriosis becomes the most common cause of pelvic pain and infertility women. The cause of endometriosis has ever been entirely proven. However, an increased use of commercial feminine hygiene products such as tampons and sanitary napkins was considered one of the major affect. Harmful substances in feminine hygiene products was analyzed and evaluated. Samples of commercial products obtained from Korea, Japan, America, Germany, and China were analyzed for six hazardous inorganic elements (chromium, cobalt, nickel, copper, cadmium and lead). In the extractable heavy metals of napkins, Cr, Ni and Cu were found in all of the samples, while Cd was detected only in two samples. In the tampons, Cr, Ni and Cu were found in all of the samples. The presence of Co and Cd was not detected in all samples The concentrations of extractable heavy metals in the tampons were lower than those in the sanitary napkins. The content of extractable heavy metals in the sanitary products was compared with the criteria of the 100 $\ddot{O}KO$ TEX Standard. It was confirmed that the level of heavy metals in the sanitary products posed no serious risk to health, based on the human-ecological criteria defined by the 100 $\ddot{O}KO$ TEX Standard.

Nowadays most business organizations wish to hire competent people who can do their own jobs efficiently right after their employment. The primary goal of this study is to focus on how we can train undergraduate students in academia-industry collaboration to satisfy this requirement. By making use of the funding from the Ministry of Education & Human Resources Development to support academia-industry collaboration program, we established an intramural company, Hankyong Design Company, and set up several studio courses for junior and senior students. To develop these courses efficiently for the first semester of 2005, studied both intramural and extramural environments of academia-industry collaboration and searched for good examples of them. Based on this investigation, I made some assumptions that how we can perform the academia-industry collaboration program for undergraduate students successfully. I chose several design tasks related to digital communications, and appointed WisePost Inc., an Internet communication service company for MSN Messenger, to be a collaborator. We made the 'Interactive Design' studio courses together and applied the courses to 20 juniors. At the end of the semester, we evaluated the works of the students, and selected and commercialized some excellent items among them. During the course work, I realized the fact that education programs in academia-industry collaboration is feasible for undergraduate students majoring in design. I understanded the overall merits and demerits of conventional studio and academia-industry collaboration courses. In addition, the results from the present study suggest that the role of professor in academia-industry collaboration program would be quite different from conventional studio courses.

Although air, water, and noise pollutions have been widely recognized, electromagnetic forces (EMF) hazard has been rarely recognized as a pollution and very little studies has been done in this country. Thus, in this study electromagnetic forces radiated by various home appliances, office machines, and communication equipments were measured and so were several places radiating strong EMF such as subway stations and electric substations. Among the home appliances microwave oven radiates lots of magnetic field and microwaves, and electric mattress does strong magnetic field. In video game room strong magnetic and considerable electric fields were measured. It was observed strong magnetic field inside of electric powered train and very strong magnetic and electric fields on some platforms. Hand-phone and car-phone radiate very hazardous level of microwaves to brain and that they rapidly come into wide use. In this study data base for various electric machines and places radiating strong EMFs were constructed and could be used for future epidemiological studies.

The purpose of this study is to investigate teachers' perception of core competencies and affective aspects in mathematics. For this purpose, a nationwide survey was conducted. The survey questionnaire consists of three core competencies including problem solving, reasoning and communication, and two affective aspects including good human nature and attitudes. The survey results were further analyzed based on school level, teaching experience, location of schools, and types of high schools. As a result, four findings were identified. First, elementary school teachers tend to put more emphasis on core competencies and affective aspects than secondary school teachers do. Second, in elementary school level, longer teaching experience is correlated with more positive perception of core competencies and affective aspects. However, there was an opposite tendency in secondary school level. Third, teachers working at schools in metropolitan cities tend to emphasize core competencies and affective aspects more than those at schools located in mid-sized cities and rural areas. Fourth, the school types in high school didn't seem to affect the teachers' perception on core competencies and affective aspects.

Introduction : One of the important domains in OT is performance skills which include sensory perceptual skills, motor and praxis skills, emotional regulation skills, cognitive skills, and communication/social skills. All of these skills are support ed by integrated neurological processes. Body : Stereology robust tool when employed to investigate morphological changes in neurons, cortex area, and specific parts of brain involved in special brain function. Stereology is an interdisciplinary field focused or analyzing biological tissue with the three-dimensional interpretation of planer sections by using estimating method and mathematically unbiased sampling. With the unbiased stereological method based on probability theory, researchers can estimate morphological and anatomical changes in biological reference areas accurately and efficiently. Changes in anatomical and cytoarchitectural parameters, such as volume, number, and length, affect specific brain function related to the brain area. Occupational therapists provide treatment to improve functions for participation of occupation in neurological disorder. The functional improvements in neurological disorder reflect neurobiological changes because functional difficulties, such as motor cognitive disorder, are due to neurological disturbances. Thus, combination of two kinds of evidence, neurological changes and functional improvement, provide fundamental evidence for OT intervention in neurological disorder. Even though most of stereological studies are in animal model and in postmortem human because of practical and ethical issues, stereology provides fundamental knowledge to support OT theory and practice. Conclusion : Therefore, stereology informs translation from neuroscience to OT based on structure-function relationship in performance skills and experience-dependent neural plasticity.

The freedom of assembly is the fundamental freedoms guaranteed by the Constitution. However, as far as our reality is concerned, the freedom of assembly is guaranteed only when it is under the control of the police, and otherwise it is perceived as an object to be suppressed. Police say even that they will not tolerate even a small illegal law while referring to the "broken window theory". Therefore, regardless of the peaceful nature of the rally, it is too obsessed with 'compliance'. This attitude is causing the citizens who participated in the assembly to be put to the object to be suppressed. This paper analyzes the requirements and current status of police force, focusing on the vehicle-wall-blocking and water cannon as a means of using the police force, which is a recent problem, and suggests ways to improve it. First of all, the installation of the wall cuts off the essential communication function of the assembly by separating the meeting place from the object of protest. Thus, despite the warning for prevention in the face of illegal acts, other than installing a barrier, it should be allowed only in the 'urgent case where there is a risk of causing damage to the life, body or property of the person'. Without this urgency, the vehicle-wall-blocking should not be allowed to be proactive as well as preventive. Secondly, the water cannon is a police force that is likely to harm people's life and body. Therefore, aiming shots, which could pose a significant risk to the human body, should in principle be prohibited. However, considering its risk, it should be supplementary used only when there is no other alternative, only when the direct risk to the legal interest of the other person or the order of public well-being is 'obvious'. In addition, as for the use standard of such a thing, it is necessary to be specified by law.

This study tries to examine the level of safety consciousness and first aid knowledge of 124 college students who attend non-public health departments in Gwangju from April 1 to 30, 2003 and apply the results of the study to curriculum. The results of this study are as follows; 1. On experiences of need of first-aid, 87.5% of respondents said 'yes' and there was a significant difference in the number of their siblings($x^2$ = 7.482, p = .048). 2. Sources of education of first aid were mostly at school(46.8%), no education(23.4%), through mass communication(22.6%) and by themselves(7.3%). There were significant differences by characteristics in sex($x^2$ = 30.230, p = .000), year($x^2$ = 10.821, p = .013) and mother's education($x^2$ = 18.932, p = .025). 3. Sources of information of first aid were mostly through TV(46.8%), followed by others (42.7%), newspapers(7.3%) and magazines(3.2%). 4. On the opinions of the most suitable period for educating first aid, elementary school was highest(41.9%), followed by kindergarten(29.0%), middle school(21.0%) and high school (8.1%) and there were significant difference by characteristics of subjects in sex($x^2$=9.689, p= .021) and year($x^2$=19.661, p= .000). 5. Score of knowledge level of safety consciousness was mean $71.58{\pm}12.05$ based on Likert 5-point scale with a full mark of 100 points and there was a significance only in current residence of subjects' general characteristics(F or t=3.894, p=.023). 6. Score of knowledge level of first aid was mean $62.73{\pm}13.29$ based on Likert 3-point scale with a full mark of 90 points and there was a significance only in residential type of subjects' general characteristics(F or t=3.058, p= .031). Although college students felt needs of first aid more than middle and high school students, it was found that their actual safety consciousness and knowledge level of first aid were low. Therefore, knowledge and ability should be developed to save human life from all kinds of emergencies and safety accident and first aid subjects should be separated in college curriculum and opportunity for actual education should be given.
