In the coagulation/sedimentation (C/S) process of the water treatment process, the inflow of massive algal bloom causes many problems including fouling of filter media. This study was conducted to find out the way to remove the algae's harmful effects by addition of pre-treatment prior to C/S process. Many Jar-tests were conducted such as (1) ACF (Algae Coagulation Flotation) process using natural algae coagulant (Water $Health^{(R)}$), (2) ACF + C/S process and (3) C/S process with a variety of conditions using cultured algae. The average values of turbidity were (1) 0.42 NTU for ACF process, (2) 0.13 NTU for ACF + C/S process and (3) 0.25 NTU for C/S process. It was shown that the treatment efficiency of ACF process could get low turbidity results, and ACF + C/S process could achieve more efficient results than those of C/S process. Any negative effects of ACF process to the efficiency of C/S process were not observed in ACF + C/S process. In order to reduce the unfavorable effects of algae, it was found out that the introduction of ACF process in the forms of (1) ACF or (2) ACF + C/S could be one of the effective and alternative solutions.

The decay of the Old Chinese Dynasty, Tang in the 10th century caused the collapse of the political order of Southeast Asia and the neighboring countries began to try to go their own way. Japan abolished the system called "Yudangsa" and nourished the culture of Japanese style. The fang age had a respect of the′Japanese Character Culture", in which when we expressed the sound, they developed the Japanese letters ,that is, reduced Chinese characters, and systematized them as linguistic symbols and developed them into one of letter design styles. The Japanese letters which was mainly the media of the expression of the female literature were delicately shaped ′as natural materials, which finally resulted in Japan′s oldest letter modeling, Asite Letter Design Style. The Japanese letters were blended with ′Reeds around the Lake", "Sea Birds", "Birds′flying", and "Rocks", mixed with the overall shapes of the objects and assimilated into one part, and became a means for the main entertainment of the nobility such as "Singing Festival", "Conference", and "Ceremonial Events" According to the relics, the Japanese feeling of a small cosmos was represented with the fabulous skills of artifacts. In audition, "Play Painting"in the countryside is also a kind of Asite the ordinary people accepted as wit and satire. What we will have to notice is about exchange of the Chinese letter designs, when the thought focused ′on the letter design, Jobcheso was popular. The letter design Jobcheso is -a kind of letter design which represents -natural objects and was popular at the time of Yukjo Dynasty, and there are some documents of that period left both in Japan and Korea. "Hyojedo" in Korea is supposed to have been influenced by the letter design. Asite- is also considered to have been "Japanese Letter Jobcheso." Therefore, the purpose of this study is to look into the origin of the letter designs in the Chinese character culture circle, in terms of the letter design of Jobcheso.

Typography is the combination of language of formative art. It is indeed the core means of human communication through understanding of language and formative values. Studies began on introduction of various techniques to overcome the phenomenon of the 'reaction of language', which appears as an impediment in delivery and sharing of information as the most fundamental roles. Successively, mobile printing types more readable and effective in delivering of meanings have been developed, thus widely distributed for general use. However, although such printing types might be easily used in image and digital media, such as in computer monitors, screens and mobile phone LCDs, etc., it is in fact difficult to use these printing types in printed surfaces, the traditional medium of information delivery, or in sign systems frequently encountered in our surrounding environment. As a solution for this, it is intended to create an effect of communication closer to dynamic typography expression by approaching visual message delivery system from the essence and substance of the color application, which corresponds to the visual spatial expression effect, the core element of expression in dynamic typography to possess significantly more powerful effect in terms of both message delivery capacity and readability than the conventional means of static typography.

The reading activity of university students is the key element for the cultivation of creative human resources, and each university develops and performs the various cultural education and library program. Actually, the university libraries check the service periodically through library satisfaction surveys and the library user's actual condition survey to improve it, but the amount of reading, number of books lent and the rate of borrowers are still under expectation. Therefore, in this research, an in-depth analysis of lending books data for freshmen, as the service improvement and revitalization measures of university libraries for students, suggested the following: (1) the early education for the library users, (2) the opening of the students-participating library collections, (3) the use of the data using a library for the consulting with students (4) the establishment of the library depositary for education support, and (5) the introduction of the library CRM for individual student. Through this result, it would be substantially helpful for each university library (including two-year college), in which the number of lending books and the rate of borrowers are below expectations.

Introduction: The impact of cervical cancer prevention programs depends on persuading women to go for screening and, if needed, treatment. As part of an evaluation of a pilot project in Indonesia, qualitative research was conducted to explore the factors that influence women's decisions regarding screening and treatment and to generate practical recommendations to increase service coverage and reduce loss to follow up. Methods: Research was conducted at 7 of the 17 public health centers in Karawang District that implemented the pilot project. Interviews and focus group discussions were held with 20 women, 20 husbands, 10 doctors, 18 midwives, 3 district health officials, and 16 advocacy team members. Results: Free services and mobile outreach events encouraged women to go for screening, along with promotional efforts by community health workers, advocacy teams, and the mass media. Knowledge and perceptions were the most important barriers to screening: women were not aware of cervical cancer risks, did not know the disease was treatable, and were fatalistic. Factors facilitating treatment were social support from husbands, relatives, and friends and the encouragement and role modeling of health workers. Barriers to prompt treatment included limited access to services and the requirement for husband's consent for cryotherapy. Conclusion: As cervical cancer prevention services are scaled up throughout Indonesia, the findings suggest three strategies to expand screening coverage and ensure prompt treatment: strengthening community mobilization and advocacy activities, modifying the service delivery model to encourage a single visit approach to screening and treatment, and working to gain men's support.

Using robots in the programming classes may help to induce learners' interest and motivation. However, simple introduction of new media, such as robots, may cause to increase learners' interest level temporarily, but also may give cognitive overload and offense against learning motivation. We developed a robot programming course to induce intrinsic motivation and to reduce cognitive load for learners in the programming education. And then, we implemented the developed course in college programming classes and analysed the educational effects of robot programming learning on novice learners' flow level. We found that robot programming course was helpful in enhancing novice learners' flow level. Especially, the element of 'autotelic experience', which explains an intrinsic motivation, was higher than conventional programming course group. It means that the developed strategies for robot programming course provides positive effects on learners' intrinsic motivation.
