The purchase of items in e-commerce is a little bit different from that of items in off-line. The recommendation of items in off-line is conducted by salespersons' recommendation, However, the item recommendation in e-commerce cannot be recommended by salespersons, and so different types of methods can be recommended in e-commerce. Recommender system is a method which recommends items in e-commerce. Preferences of customers who want to purchase new items can be predicted by the preferences of customers purchasing existing items. In the recommender system, the items with estimated high preferences can be recommended to customers. The algorithm of collaborative filtering is used in recommender system of e-commerce, and the list of recommended items is made by estimated values, and then the list is recommended to customers. The dataset used in this research are 100k dataset and 1 million dataset in Movielens dataset. Similar results in two dataset are deducted for generalization. To suggest a new algorithm, distribution features of estimated values are analyzed by the existing algorithm and transformed algorithm. In addition, respondent'distribution features are analyzed respectively. To improve the collaborative filtering algorithm in neighborhood recommender system, a new algorithm method is suggested on the basis of existing algorithm and transformed algorithm.

The Vampire has relatively universal images in through the cultural and verbal usages. The comic Higajima and movie display the latest image of Japanese Vampire of asian mode of production. After the Meiji political reformation of 18th Century, Japanese had rapidly changed into European style in every places. However, the Higajima is denied the structural changes, it is insisted that the changing is only the skin deep and colour of hair but the structure of the society is same as feudal Japan. Asian mode of production is claimed by Karl Marx, according to him, it is before the historical developing model in Europe and it was controversial. The major character of modern Japanese history would be the change of hierarchy of king-shogun-samurai-peasant based on the regional ground. The feudal structure is changed by the Meiji reformation and Japan was rushed for the westernized country rather than the asian mode of production. However, Higajima argued that the changing is just the clothes of ruler but the democracy and individual citizenship was lost in that reformation. Vampire is cursed creature that cannot see the sun and it has not the functioned as a human organ. For human it is dead but this creature actively moves and stronger than human and much superior than human in every aspects. It is managed the feeding through the suck the human blood and power to seduction. Even it is not exist, it is quite symbolic phenomenon of cultural usage of superior entity of chain of feeding. The aim of this paper is display the symbolic code Vampire of Asian mode of production in Higajima and political struggling of Japan in actual. To search of the cultural meaning and possibility of the Korean solution of modernity.

Middle and high school girl students' menstruation characteristics, appearance of menstruation dysmenorrhea, and coping with the menstruation dysmenorrhea were examined in order to give information in instructing girl students about menstruation dysmenorrhea, in delivering health education in the school, and establishing health policy. 970 girl students in middle and high schools in Cheju-do were selected and surveyed using the questionnaire the author developed based on the previous studies. The findings are as follows. First, the age of first menstruation was average $12.9{\pm}1.22$ years. The younger they were, the earlier their first menstruation came. The most common menstrual cycle was such one that continuously irregular from the beginning or that regular and irregular cycle run together. The first irregular menstrual cycle changed regular one within 1 or 2 years. Most of the respondents had normal menstrual cycle of $21{\sim}35$ days and menstruation period of $3{\sim}8$ days. Second, symptom of menstruation dysmenorrhea was orderly; hurt in the underbelly, tired, hurt in the waist, and headache. It was higher with high school students than middle school students. For the most part, time of heavy menstruation dysmenorrhea was the 2nd day after menstruation starts and period of menstruation dysmenorrhea was 2 days. More than the half of the respondents felt that the present menstruation dysmenorrhea was similar with the first one and they felt not comport in daily life due to menstruation dysmenorrhea, and 'hard to live a normal life' was higher with the high school girl students than with the middle school students. Third, how to cope with menstruation dysmenorrhea was enough sleep, relax and rest, taking a hot water shower, listening to music or watching a movie, taking medicine, and doing excercise. Few of the respondents have ever visited a doctor due to menstruation dysmenorrhea, and the reason was mostly irregular menstruation and heavy dysmenorrhea. Forth, when they took medicine due to menstruation dysmenorrhea, they gathered information on the medicine from family members and friends, while extremely low from a pharmacist or a doctor. The most of them have ever took medicine during menstruation once and took standard dose. While excess dosage was higher with high school students than with middle school students. From these findings, a good many girls are experiencing menstruation dysmenorrhea since their first menstruation. To discover early the severely abnormal findings and to treat, more interest from home and school, counseling and sexual education on time, and expert's diagnosis are necessary. Rather than unconditionally taking pain-relievers which can plainly solve the pain, continuous health education at home and in the school should be carried on for the girls to practice proper measures one think effective or an expert recommends.

In this paper, we propose a synchronized playback method of 3D reference model and video by extracting golf swing information from learner's golf video to precisely compare and analyze each motion in each position and time in the golf swing, and present the implementation result. In order to synchronize the 3D model with the learner's swing video, the learner's golf swing movie is first photographed and relative time information is extracted from the photographed video according to the position of the golf club from the address posture to the finishing posture. Through applying time information from learners' swing video to a 3D reference model that rigs the motion information of a pro-golfer's captured swing motion at 120 frames per second through high-quality motion capture equipment into a 3D model and by synchronizing the 3D reference model with the learner's swing video, the learner can correct or learn his / her posture by precisely comparing his or her posture with the reference model at each position of the golf swing. Synchronized playback can be used to improve the functionality of manually adjusting system for comparing and analyzing the reference model and learner's golf swing. Except for the part where the image processing technology that detects each position of the golf posture is applied, It is expected that the method of automatically extracting the time information of each location from the video and of synchronized playback can be extended to general life sports field.

The purpose of this study is to provide the demand information about services (S/W) and infrastructure (H/W) for rural welfare and culture. The survey was conducted on the overall satisfaction level, the condition change, the importance-satisfaction level of each field and the top priority items for administrative agencies and rural residents. In the overall satisfaction level, administrative agencies responded more than 'normal' to all fields, but the overall satisfaction level was lower than 'normal' in the fields excluding the healthcare field in the case of rural residents. In terms of condition changes compared to the past five years, both administrative institutions and local residents evaluated the improvement. IPA analysis was conducted to identify the priority ranking of each field and it was found that emergency medical facilities in the healthcare field, infant day care facilities in the social welfare field, movie theaters in the culture field, lifelong education institutions and academy facilities in the education field and private sports facilities in the leisure and sports field were most needed, respectively. The results of this study are expected to be helpful in increasing the efficiency and presenting the improvement direction about the development policy of the rural culture and welfare.

Through the comparative analysisand inductive research on main creation styles of Chinese, American and Japanese animation films, a conclusion can be given out, which means that the animation film style of each country can hardly be formed without their own traditional painting art, aesthetics habits and ways of thinking. It is these characteristics that form their unique animation film style. America emphasizes realism art, development and utilization of new technology, Japan pays sepcial attention totraditional painting art and comic stories. In business aspect, they bring about different business models relying on the experience of satisfying the diverse needs of domestic and global entertainment markets. When it comes to the content field, they carry forward universal values and meet the individualistic heroismso that a variety of business animation films and art animation films find their ways into the global market and acquire great popularity among audiences from all over the world. Through the comparasion of American and Japanese animation films, a new view to analyze the animation films of China is created. Animation creation is largely based on the need of socialist ideology from 50s to 80s. Even though the purposes of animation film creations returned to satisfying the diverse requirements of commercial markets and audiences, the consequences, such as the break gap of creations and talents, the lack of diverse creative styles and commercial market operation mechanism, sitll affect China's animation films today. Japan found thier position from the American model and became successful. Nowadays, China need find our own creative style and position from American model and Japanese model. And the systematic reformings that are detailed in the government managements, industry standards, internationalized talents cultivation and accumulation are the essential point.

When writing historical dramas, there was an argument that restoring the language of the times was the responsibility of the playwright, but no full-scale research was done. There was no collaborative study between playwrights and Korean Language scholars. So far, many playwrights have considered it the responsibility of Korean Language scholars to discover and restore language. However, it is a medium that can easily meet the public like a play or movie, and it should have a great responsibility for creation. Language changes with time, so restoring the language of the time in plays and scenarios can lead to difficulties in communicating with modern audiences. However, the change of language according to the times means that it captures the social image and fashion of the time Therefore, language restoration in historical dream means that scenes and backgrounds can be described more realistically. Restore of language is not just necessary to improve the creative environment; it should be understood as the responsibility of the artist to meet the ability of the audience to understand the language of the times already learned. The playwright who writes the historical drama should not only learn the grammar of the background era, but also find out the lost pronunciation and the changed vocabulary so that he can use various dialogues.

Popcorn grains are consumed around 10,000 tons per year, in South Korea. It is consumed in amusement parks, movie theaters and snacks. The size of the popcorn processed market in Korea is estimated to be 3.6 billon won per year. So, the popcorn grain market has good prospects. On the other hand, domestic grain is at the level of 1 %, which is less domestic production than the size of the market. Maize Research Institute has developed domestic varieties in order to increase the use of domestically produced grains. The Oyrunpopcorn variety which was commonly distributed is a preferred cultivar because it has a good popping rate compared to imported grains. In addition, 'G-Popcom', 'Oyrun #2' and 'Kichan Popcorn' were developed, which diversified the choice of the farmers. Yield per unit area is important to improve farmers' income. At present, domestic grain production is traded at 5,000 won/kg, so if the yield improves, a high farmer^ income is expected. Therefore, this study compared the growth characteristics and yield according to the appropriate sowing time and plant density to improve the yield of domestically grown popcorn. We used 'Oryunpopcorn', for this research. Agronomic characteristics were compared by sowing times April 23, May 22 and June 22. The 100 seeds weight were 15.9g, 17.7g and 15.0g, respectively. Kernel weight planted in May 22 is the highest value. Yield per 10a were 414kg, 434kg and 296kg, respectively. It shows the yield planted in May 22 was higher than other trials. Therefore, the sowing time to increase the kernel weight and yield is appropriate for planting in mid-May. The number of plants in planting density trial was 5,700 plants, 4,700 plants and 4,000 plants in 10a area. Plant height at each trial were 221 cm, 214cm and 218cm, respectively. It was the highest height in 5,700 plants trials. The 100 kernel weight were 14.8g, 15.9g and 16.5g, respectively. Low planting density trial indicated high kernel weight. Yield per 10a was 415kg, 357kg and 314kg, respectively. It was higher at high density trial than other experimental plots. Therefore, appropriate sowing time was in mid-May and planting density was 5,700 plants/10a in order to increase the yield of popcorn in South Korea. This study will be useful for farmer's income to use the domestic cultivars.

This study was attempted in order to understand leisure phenomenon in Korea cultural area through relation of Leisure Activity, Leisure participation motivation, self -efficacy and Subjective well-being. The purpose of this study was to investigate the question that Leisure Phenomenon was studied focus on specific Leisure activity contents such as physical, tour science, though it is an important subject to explore as psychological and cultural. Also it suggested that what was the problem of established studies and what was the directions for future study. Concrete study problem was assumed three issues. (1)General state of leisure activity and leisure motivation in Korea, (2)The correlated relation between each motivation and self-efficacy and (3)The correlated relation between each motivation and Subjective well-being?. Through this, we conducted three results. Frist, the leisure motivation scale was factor analyzed and consequently 2 factors which can be considered as leisure motivation were prescribed. Also through the responded data, leisure activity of university students showed much more passive activity(e.g.,reading, listening music, movie, watching TV, Internet surfing etc.) than positive and physically activity. Second, each motivation was not significant in self-efficacy. Finally, among the motivation, especially emotion and psychological rest motivation was significant in the subjective wellbeing. These findings imply that general understanding about leisure phenomenon can different as the cultural thinking of leisure activity and leisure motivation.
