There are people who are sensitive to cosmetic ingredients, such as pregnant women and skin disease patients. There are also people who experience side effects from cosmetics. To avoid this, it is cumbersome to search for harmful ingredients in cosmetics one by one when shopping. In addition, knowing and remembering functional ingredients that suit you is helpful when purchasing new cosmetics. There is a need for a system that allows you to immediately know the cosmetics ingredients in the field through photography. In this paper, we introduce an application for smartphones, <Hwa Ahn>, which allows you to immediately know the cosmetics ingredients by photographing the ingredients displayed in the cosmetics. This system is more effective and convenient than the existing system in that it automatically recognizes and automatically classifies the ingredients of the cosmetic when the camera is illuminated on the cosmetic ingredients or retrieves the photos of the cosmetic ingredients from the album. If the system is widely used, it is expected that it will prevent skin diseases caused by cosmetics in daily life and reduce purchases of cosmetics that are not suitable for you.

The goal of this research was to provide the basic data of sexual education for late schooler by finding out what they want to know about sex, or to see, if any, its relevancy between female and male students and between each grade. The sample for this research was a total of 453 students in 4th, 5th and 6th grade from 12 different classes at two elementary schools which were located in C city and in B province. The children were requested to write down three points on what they want to know or to learn most about sex, and their answers were put through two analytical stages in order to classify and to examine. The followings are the conclusions from the data. 1. The female cluster took 44.2% out of the whole sample, and there were 151 students per each grade. The specific girl ratios for each grade were 42.4%, 50.3% and 39.7% respectively. 2. It was noted that a total of 1,195 questions were gathered from the students writings, 45% of the questions was raised by the female students. The 4th grade students raised 432questions (43.8% by the girl) while the 5th. and the 6th grade students raised 387 (53.2% by the girl) and 376 questions (42.3% by the girl) respectively. The average number of questions per students was 2.6 while the female students raised 2.8 questions which was more than the average 2.5 questions by male students. It was the 4th grade female student cluster, which raised the most question (3.0) while the 6th grade male students raised the least question (2.4) in average. 3. The questions raised by the children could be divided into seven categories of the knowledge need on sex. They were Reproduction (310 questions, 25.9%), Sexual Culture (230, 19.2%), Concept of sex (125, 18.0%), Changes of Puberty (172, 14.4%), Sexual Health (119, 10.0%), Anatomy and Physiology of Reproductive System (78, 6.5%) and Sexual Tendency and behavior (71, 5.9%). 4. 'Reproduction' was the most frequently raised questions not only by both sex groups but also by the 5th grade students. Both sexes in the 4th grade showed the highest interest in Sexual Culture while it was Changes in Puberty for the both sexes in the 6th grade. The knowledge need on sex of the children indicated what they understand sexuality. They apprehended sex as sex, gender and sexuality in an inclusive way. They showed a major interest in the biological sex and the sexual activities. It seems that the children managed to understand clearly the meaning of gender, furthermore, they even pointed out that the streotyped sex role, patrimonial system and the sexual discrimination were unreasonable. The students possessed not only the least but also the most negative understanding in regard of sexuality. Two suggestions were made from the above conclusions for the practical sex education as well as its research. 1. For the practice: The sex education for the elementary upper grade school student should be relevant with their cognitive characteristics, also it should be more specific on the reproductive organs of both sexes, the actual scenes of the pregnancy and child delivery procedures. The gender concept should be added to the biological sex education, which will lead them to understand the unreasonableness of today's male-superior phenomenon and correct them. It is also necessary to develop educational programs for this age group so as to help them to understand sex in the sense of sexuality as well. 2. For the research: It is not easy to draw out a through conclusion since this study was carried out as one-time data collection. Yet it is undeniably helpful for the sex education if we can understand what the children want to know about sex, how much they know about it by conducting deep-interview researches through a small number of sample.

Objectives : This study had been performed for Respondents who live in Daegu and Kyungbuk province Age group of 30 to 50 years old. Methods : The oral health state and oral heath care, dental treatments about the use of oral hygiene devices were obtained through self-administering questionnaires from 2 to 31, January, 2009. Results : 1. The toothpick was well known for respondents and automatic brush, gargle, dental floss were practically used. 2. 57.1% of man know oral hygiene device, they know more about oral hygiene device if they have higher degree, and they use more if they are older than others. 3. 55.5% of respondents who think their oral health condition is not healthy enough recognize oral hygiene device, 77.5% of respondents who visited dental clinic around six month recognize oral hygiene device. 82.4% of respondents who had been follow-up. 86.1% of respondents who think their oral health state is good enough doesn't use oral hygiene device, oral hygiene device was used more for respondents who visited dental clinic frequently. 47.1% of respondents who visited dental clinic periodically use oral hygiene device. 4. Respondents who experience implant recognize more about oral hygiene device and periodontal Tx, orthodontics problem, preservative treatment were next. 5. 60.0% of respondents who were educated tooth brushing method recognize it. Oral hygiene device was frequently used if tooth brushing time were increased. 26.4% of respondents who were changed their tooth brushing method used oral hygiene device. Conclusions : Their recognition level was practically low whose age is around 30 to 50. Their oral hygiene device use ratio is higher then others who were educated tooth brush method so that I think we need to recommend for use oral hygiene device and use method.

The ship movement implies current position, wave, wind, and its other factors. We need to know exactly the location and the shape of the ship and control its motion because of these effects. In order to control the small ship according to the movement of the large ship, the position and shape of the ship should be given first. In this paper we propose the method with which we know the current status of the ship without dynamic equations of the ship. There are several methods to track the system such as optical, radio frequency, radar, camera, and infrared light. We propose the movement of the ship using the GPS absolute axis. But, the genuine error by the GPS itself and the movement of the ship cause the result of the GPS of not being accurate. This paper reduces the error of the location and the shape of the ship and gives the exact values of the ship movements even if the GPS implies some error itself.

As the motion response of heave for floating bodies on the water surface is relatively large near the natural frequency, it is necessary to predict its value accurately from the stage of initial design. Bodies accelerating in fluid experience force acted upon by the fluid, and this force is quantified by using the concept of added mass. For predicting the natural frequency of heave we need to know the added mass, which is given as a function of frequency, and hence the natural frequency can be obtained through only by iteration process, as was pointed out by Lee (2008). His method was applied to circular cylinders, and two dimensional cylinders of Lewis form by making use of the Ursell-Tasai method in the previous works, Lee and Lee (2013), Kim and Lee (2013), and Song and Lee (2015). In this work, a similar algorithm employing the concept of strip method is adopted for predicting the heave natural frequency of KCS(KRISO Container Ship), and the obtained computational result was compared with other existing experimental data, and the agreement seems reasonable. Furthermore, through the error analysis, it is shown that why the frequency corresponding to the local minimum of the added mass and the natural frequency are very close. And it seems probable that we can predict the heave natural frequency if we know only the local minimum of added mass and the corresponding frequency under a condition, which holds for ship-like bodies in general.

Purpose: Menopausal syndrome is caused by urgent changes of sex hormone in women. The hormonal therapy can soothe the problems of menopausal patients, but it can increase the probability of another disease, such as breast cancer, heart attack, etc. So the demand of alternative herb therapy is increasing in Western countries. In Korea, herbal medicine is imported and used by Western doctors. To know and use the alternative herbal medicine, Korean Medical doctors should know their efficacy and safety. Methods: We researched the Medline(Pubmed) with the key word such as 'CAM', 'herb' and 'menopause'. We selected the herbs known as treating the menopausal syndrome and researched the similar or same herbs that are used in Korean medicine by the scientific name and efficient ingredients. To evaluate the efficacy of the herbs, we compared the herbs that were differently defined in alternative and Korean medicine Results: Balm, black cohosh, chaste berry, dong quai. evening primrose oil. ginkgo, St. John's wort, valerian root, and sarsaparilla were chosen as prevalent herbs used in alternative medicine. The pharmacologic effect of Black cohosh, licorice root, St. John's wort were recognized. But these three herbs are not usually prescripted for menopausal patients in Korean medicine. So we could apply these three herbs as one of Korean medical treatments. The efficacy of other herbs cannot be surely prescripted for menopausal patients. Conclusion: The efficacy and safety of alternative medicine is not proved yet. But to diversify the treatmental methods of Korean medicine, we need to prove and use these medicine as one of Korean medical treatment.

As we know, Incoterms are reflecting only the greatest common measure of practice in int'l trade. Therefore we can think them as the commercial practice most widely used in trade. They contain a number of detail under converse mirror image terms because they connect each other like a thread as to all oversea's commercial transactions between importing buyers and exporting sellers. Therefore they afford convenience to exporters and importers in the world because they tell the parties what to do as to transfer of risk and costs, responsibilities in connection with delivery of the goods. Nonetheless, since Incoterms 1936, they have been periodically revising in order to represent contemporary commercial practice. Therefore, according to change of Int'l trade environment, ICC plans to modify to the 2000 Incoterms. I hope to contribute to revising works by reference of above mentioned revision, that to say, aspects of provision, reflection of prevailing most commonly used, promotion of status as uniform rules, provision of convenience of int'l buyers and sellers. harmony with existing int'l instruments, presentation of criteria in variation of Incoterms.

This study is aimed at proposing a new approach to designing UDSS (Ubiquitous Decision Support System) which allows context-awareness and connectivity. In the previous studies, the need to design UDSS and analyze its performance empirically was raised. However, due to the complexity of empirical approaches, there is no study attempting to tackle this research issue so far. To fill this research void, this study proposes a Mobile Delivery System (MDS) as a form of UDSS, empirically analyzing how users perceive its context-awareness and connectivity functions. Especially, to add more rigor to the proposed approach to know how much it works well in the decision-making contexts, we considered three decision making phases (intelligence, design, choice) in the research model. With the valid questionnaires collected from 340 users of the MDS, we induced statistically proven results showing that both context-awareness and connectivity of the proposed UDSS (or MDS) influence the decision making steps positively and then contribute to improving the decision making quality.

The development of Korean textile industry has continued for the early industrialization. But a change in situation of circumstances, textile industry undergoes hard times. To overcome the barrier, therefore, technical development and design innovation are needed to make high value added product. This paper try to put to practical use of the silk weighting process technique(WPT). First, we investigate the technical trend of WPT to summarize the theory, and examine the feasibility of technical development. Second, the application of Graft process to silk textile is examined to know whether it is possible as an practical use. Next, we present the practical way of WPT using MAA monomer through experiment. The results are as follow. 1) Considering the lack of silk yarn. Graft process is appropriate new technique to make the value added product, and fine quality. 2) Studing textile goods, it need inter-displlinary co-work not only fiber engineering scope because textile goods is closely related with fashion industry. 3) MAA monomer used in this paper is more excellent then other monomer because it has good weighting effect and does not harm to the nature of textile. 4) MAA WPT is good for silk textiles of ladies jacket and neck-tie.
