The purpose of this survey is to measure the sexual knowledge, attitude, and experience in college students in order to provide better sex education programs and direction. For this study, questionnaires were given to 259 students in K college of Kyongnam and collected during the period of June 1 to June 20, 1998. Data was analyzed using a statistical computer package: SPSS to manipulate the data along with frequency, mean, t-test, F-test and Pearson correlation coeffiency. The results from this study were summarized as follows: 1. Sex related knowledge marked 12.01 at a maximum level of 25. In the areas of Sex physiology(51.8%), genital physiology(49.9%), venereal diseases(44.3%) and contraceptive methods (38.1%), students were shown to have certain levels of knowledge. 2. Sex related attitudes marked 15.35 at a maximum level of 35. The most frank attitudes concerned 'premartial coitus in males' and the most conservative attitudes concerned 'extramarital coitus in females'. 3. Concerning sexual behavior 80.7% of the respondents had associated with the opposite sex. The most frequent behaviors were walking arm in arm (male : 28.6%, female: 36.2%). Their main problems were relationships with the opposite sex(male : 39.2%, female: 24.5%), frustrated sexual desire(male : 26.0%, female: 9.8%) and unwanted pregnacy(male: 15.2%, female: 7.8%) To solve sex problems, respondents intended to consult their friends(male : 35.7%, female: 46. 7%) and become active in sports or recreation (male: 23.4%, female: 11.4%). About 81.2% of male students had a masturbation experience, but only 11.4% of female did, 40.0% of male students had a sexual intercourse experience, but only 13.3% of females did, 7.8% of male students used contraceptive methods, but only 2.9% of females did. 12.3% of male students had a rape experience, but only 10.5% of females did. The proportion of male students who made someone pregnant was 12.3%,however pregnant female were only 6.8% and the proportion of male students who forced someone to have an abortion was 12.3%, females who experienced an abortion were only 5.7%. 4. Regarding genital physiology, there was a statistically significant differences in gender ( t = -7.342, p=0.000). Regarding contraceptive methods, there was a statistically significant difference in the father's education level(F= 2.421, p=0.036) 5. In sexual attitudes, there were statistically significant differences in gender( t = 4.456, p = 0.000), religion(F=4.315, p=0.000), high school(F=3.150, p=0.045), habitation form(F= 3.164, p=0.0025 and methods of acquiring sexual knowledge(F=2.990, p=0.012). 6. The variables regarding sexual experience were gender, high school, economic status, habitation form, method of acquiring sexual knowledge, and parental attitudes toward sex. From the result of the study, sex education is required and must be taught as a regular course in the curriculum of all Korean schools at all levels.

Objectives: The purpose of this study is to find out how well the primary school students are practicing the health promotion behaviors and the factors relating their health promotion behavior. Methods: This study was carried out by using questionnaires with 1,215 students attending at a 6th grade, 16 primary schools which arranged the school health teachers in Kyoungpook, Chilkok Gun from the 21th through 22th of December 2004. Among them, 1,189 were included in final analysis. The collected data was analyzed through frequency, percentage mean and standard deviation, multiple regression. Results: According to the data from multiple regression of analysis which has the health promotion behavior practice as a subordinate variable, in male students' case the degree of health promotion behavior practice becomes high in proportion to their parents' interest in health, to their perceived self efficacy, and in case of the barriers of the health promotion behavior practice. As to the female students, their health behavior practice becomes high in proportion to their parents' interest in health. It also becomes high in proportion to the perceived health status, the understanding of the importance of the health, internal health locus of control in personality, the perceived self efficacy and the perceived benefit of the health promotion behavior. But in case of the barriers of the health promotion behavior, it was the same as the male students' case. Conclusions: As the results of study, it showed that the knowledge to importance of health, the self efficacy, the knowledge of benefit of health promotion behaviors and the health concern to the children of the parents were related to health promotion behaviors of the primary school students. So, through the systematic development of health education program, we induced to desirable direction for the changeable factors of actions to health promotion for the health, and through the connective guidelines between the School and the Home, we have to adapt to effective health promotion program for the health management of the young boys and girls.

Nowadays, it is surely the quack which stands as one of the most controversial, problematic. the quack has been a consistent target of contested public protection strategies in the past few centuries in many countries. Recently, complementary and alternative medicine (CAM) is increasingly utilized and accepted by patients and providers throughout the health care system in the world, most accounts attribute this growing acceptability to the shortcomings of conventional medicine, the appeal of CAM's core beliefs, and the growing body of research indicating that CAM actually works. However, the governments of western countries have called for measures to ensure that the public are protected from incompetent and dangerous practitioners. Common to these controversies has been a suggestion to ban, exclude or limit the medical practice of those deemed to be damaging rather than improving the health of individuals as a measure of public protection. This article describes the experiences of western counties' health care system which is moving in a more pluralistic direction. By examining the ways in which regulatory efforts in the countries have come to address what is invariably described as a growing interest in CAM, this study show how the problem of CAM/quackery today is increasingly located in an ethical field of practitioner competency, qualifications, conduct, responsibility and personal professional development, regardless of the form of therapy in question. Many countries developed a series of measures and strategies to contain the acceptance of CAM groups, such as insisting on scientific evidence of safety and efficacy, resisting integration of CAM with conventional medicine and opposing government support for research and education. In a sense, those countries' movements serve to protect not only patients, but the dominant position of medicine and its allied professions, and to maintain existing jurisdictional boundaries within the healthcare system. The popular support for CAM will require that health professional stakeholders continue to address the challenges this poses, and at the same time protect their position at healthcare system. To cope with the quack, professional body, public sector and health authorities should consider the safety of consumers of healthcare and responding to the demands of the community for CAM therapies as well as the claims of the established healthcare professions. Finally, some implications for future health care were suggested.

This study aims to prove the changes, development and social background of Korean male cosmetics over the period of 2000-2010. There were total 574 articles written about male make-up and cosmetics in Chosun Daily, Joongang Daily and Donga Daily, which are the top three Korean local daily newspapers in terms of sales revenue for that period. These articles were analyzed together with social background research from various books and daily newspapers. The analysis of articles was divided into different categories; such as foundation cosmetics, color cosmetics, hair, and the social background. It was found that the articles related to foundation cosmetics were written the most, the articles related to male appearance management were second, articles on other items including how to manage the skin being the least. As for the social background of Korean male cosmetics, first of all, a change in social recognition can be pointed out. The traditional understanding of gender roles has changed, men's appearance management has started to be regarded as a competitive talent, and at the same time, the esthetic viewpoint for men also has changed. One example is the newly made popular term, "flower-handsome man", which shows the new trend of favoring males with nice skin. Second, the expansion of mass culture can be pointed out. As consumers can get information and fashion trends easier and faster, the fashion spreads fast, and this has led to the generalization and popularization of the sense of beauty. Third, the development of scientific technology and medical science can be pointed out. Thanks to the progress in those areas. the extension of youthfulness has become possible and the cosmetics industry was also affected greatly, as shown in the market spread of functional products for anti-ageing and wrinkle control as the interest in anti-ageing has grown. There are benefits from the development of scientific technology, but the problem of environmental pollution has appeared due to machinery and industrialization and thus the issue of well-being has been raised. Rising interest in naturalism, pro-environmentalism and organic cosmetics has influenced the cosmetics industry. In addition, the quantity of ultraviolet rays exposed to our skin has increased due to the air pollution caused by the destruction of environment, leading to increased usage of sun block lotion. Lastly, the influence of consumer society and the expansion of consumerism culture can be pointed out. In the modern society, consumption acts not only as the use of products and services but it also has an important role of mediating individuals with others and the society. The market for male cosmetics has been expanding and the number of men putting on make-up has been increasing rapidly. Therefore, this study is meaningful in that the analysis of the mode of change and the social background are an essential process in order to provide a direction for the future market for male cosmetics.

This study analyzed causal relationship between electricity consumption and economic output (GDP) for Korea from 2001 to 2014 employing the vector error-correction model estimation by manufacturing sector. The results of unit-roots tests show that all sectoral GDP and electricity consumptions were not stationary. And cointegration tests show that processed foods, Wood Pulp Paper, electricity apparatus, Precision Medical sectors had a linear combinations in the long run between electricity consumptions and economic growth. With respect to the direction of causality, manufacturing sector has a uni-directional running from economic output (GDP) to electricity consumption in short term. The results of study show that sectoral causal relation were different each other in short term and long term. These findings imply that electricity demand management policy focusing on efficiency improvement is necessary to minimize negative impacts on economic growth and to adopt suitable structural policies can induce energy conservation.

Multi-modality image registration is a widely used image processing technique to obtain composite information from two different kinds of image sources. This study proposes an image registration method based on moment information and surface distance, which improves the previous surface-based registration method. The proposed method ensures stable registration results with low registration error without being subject to the initial position and direction of the object. In the preprocessing step, the surface points of the object are extracted, and then moment information is computed based on the surface points. Moment information is matched prior to fine registration based on the surface distance, in order to ensure stable registration results even when the initial positions and directions of the objects are very different. Moreover, surface comer sampling algorithm has been used in extracting representative surface points of the image to overcome the limits of the existed random sampling or systematic sampling methods. The proposed method has been applied to brain MRI(Magnetic Resonance Imaging) and PET(Positron Emission Tomography), and its accuracy and stability were verified through registration error ratio and visual inspection of the 2D/3D registration result images.

Business corporations have become specialized and on the basis of various interests try to strengthen their competitiveness through a cooperative system of purchase, distribution, service and IT technology. And an advanced Internet-based electronic commerce has witnessed explosive growth and a business-to-business (B2B) electronic commerce. Through E-marketplace. business corporations achieve such diverse utilities as expenditure curtailment, process reduction and prime cost reduction. And with business depression worldwide and soaring prices of materials, many business corporations consider the introduction of comprehensive purchase of MRO (maintenance, repair and operation) materials. The Purpose of this study was to examine the definition of B2B E-marketplace and the utilities of MRO commerce correctly focusing on an empirical analysis of cases of MRO supply and purchase business corporations. The indications acquired from this research results are as follows. Firstly, as for MRO integrated purchase under the characteristics of the market environment, it had to use the supplier obligatorily through the integrated purchase on the level of CEO's decision-making or the group rather than the voluntary will of the purchasing department or the procurement department. Secondly, as for the present B2B E-marketplace MRO purchase, the purchasing agency business has formed the mainstream, but it is aiming at the diversification of the benefit by supplementing/correcting the business model such as category type, mediation business type, MRO-type advancing in the store inclusive of the purchasing agency business, keeping pace with the potential market of MRO. Thirdly, as for analysis of the products, the purchaser wants more various products and assortment of goods than those of the present time, and also to be provided with the precise product information. Especially, as the importance of the product sourcing becomes high, the whole energy has been bestowed on acquirement of the excellent suppliers. Fourth, as for use of B2B E-marketplace MRO integrated purchasing system, there are the purchasing companies complaining the inconvenience even until now, and there is the demerit spending the long time during the image move and the process treatment. It shall try to shorten the searching time and the process treatment time as the system is centered on the purchaser. In order to enhance the efficiency of MRO E-marketplace purchase, followings must be considered: First, because the importance of product sources ever increases, an excellent supplier must be secured earnestly. Second, the time of process must be reduced focusing on purchasers. B2B E-marketplace will increase and diversify electronic commerce continuously. Through MRO E-marketplace, business corporations will reduce expenditure, achieve a transparent and speedy trade, and purchase products of fine quality, thus establishing a most effective market. In addition, in this study the investigator brings focus into MRO which has not been clearly discussed in the academic and business world so far and intensively highlights an indirect material-oriented expenditure curtailment effect. By taking all the aspects of supplier, purchaser and practical economical value into account, the investigator presents a strategic direction for the successful comprehensive purchase of B2B MRO.

Digital imaging detectors can use a variety of detection materials to convert X-ray radiation either to light or directly to electron charge. Many detectors such as amorphous silicon flat panels, CCDs, and CMOS photodiode arrays incorporate a scintillator screen to convert x-ray to light. The digital radiography systems based on semiconductor detectors, commonly referred to as flat panel detectors, are gaining popularity in the clinical & hospital. The X-ray detectors are described between a-Silicon based indirect type and a-Selenium based direct type. The DRS of detectors is used to convert the x-ray to electron hole pairs. Image processing is described by specific image features: Latitude compression, Contrast enhancement, Edge enhancement, Look up table, Noise suppression. The image features are tuned independently. The final enhancement result is a combination of all image features. The parameters are altered by using specific image features in the different several hospitals. The image in a radiological report consists of two image evaluation processes: Clinical image parameters and MTF is a descriptor of the spatial resolution of a digital imaging system. We used the edge test phantom and exposure procedure described in the IEC 61267 to obtain an edge spread function from which the MTF is calculated. We can compare image in the processing parameters to change between original and processed image data. The angle of the edge with respect to the axes of detector was varied in order to determine the MTF as a function of direction. Each MTF is integrated within the spatial resolution interval of 1.35-11.70 cycles/mm at the 50% MTF point. Each image enhancement parameters consists of edge, frequency, contrast, LUT, noise, sensitometry curve, threshold level, windows. The digital device is also shown to have good uniformity of MTF and image parameters across its modality. The measurements reported here represent a comprehensive evaluation of digital radiography system designed for use in the DRS. The results indicate that the parameter enables very good image quality in the digital radiography. Of course, the quality of image from a parameter is determined by other digital devices in addition to the proper clinical image.

In spite of the developing endovascular era, large (15-25 mm) and giant (>25 mm) wide-neck cerebral aneurysms remained technically challenging. Intracranial flow-diverting stents (FDS) were developed to address these challenges by targeting aneurysm hemodynamics to promote aneurysm occlusion. In 2011, the first FDS approved for use in the United States market. Shortly thereafter, the Pipeline of Uncoilable or Failed Aneurysms (PUFS) study was published demonstrating high efficacy and a similar complication profile to other intracranial stents. The initial FDA instructions for use (IFU) limited its use to patients 22 years old or older with wide-necked large or giant aneurysms of the internal carotid artery (ICA) from the petrous segment to superior hypophyseal artery/ophthalmic segment. Expanded IFU was tested in the Prospective Study on Embolization of Intracranial Aneurysms with PipelineTM Embolization Device (PREMIER) trial. With further post-approval clinical data, the United States FDA expanded the IFU to include patients with small or medium, wide-necked saccular or fusiform aneurysms from the petrous ICA to the ICA terminus. However, IFU is more restrictive in South Korea than in United States. Several systematic reviews and meta-analyses have sought to evaluate the overall efficacy of FDS for the treatment of cerebral aneurysms and consistently identify FDS as an effective technique for the treatment of aneurysms broadly with complication rates similar to other traditional techniques. A growing body of literature has demonstrated high efficacy of FDS for small aneurysms; distal artery aneurysms; non-saccular aneurysms posterior circulation aneurysms and complication rates similar to traditional techniques. In the short interval since the Pipeline Embolization Device was first introduced, FDS has been firmly entrenched as a powerful tool in the endovascular armamentarium. As new FDS are developed, established FDS are refined, and delivery systems are improved the uses for FDS will only expand further. Researchers continue to work to optimize the mechanical characteristics of the FDS themselves, aiming to optimize deploy ability and efficacy. With expanded use for small to medium aneurysms and posterior circulation aneurysms, FDS technology is firmly entrenched as a powerful tool to treat challenging aneurysms, both primarily and as an adjunct to coil embolization. With the aforementioned advances, the ease of FDS deployment will improve and complication rates will be further minimized. This will only further establish FDS deployment as a key strategy in the treatment of cerebral aneurysms.
