  • Cedric price is an architect and educator who have had an influence on architectural thinking through teaching and projects, rather than completed buildings. The purpose of this study was to analyze the architecture of Cedric Price in terms of time. Time was an important factor to understand his architecture along with his interest in technology, so most of his architectural thinking and methodology - anti-architecture, programmatic indeterminacy, a philosophy of enabling and so on, could be explained under the consideration of time. Depending on how he considered and used the concept of time, his projects could be categorized into two groups; The first group was related to the change over time, and this group again divided into three sub categories; change of user's preference, change of external environment, and change over building lifetime. The second group was related to planning of time, which could be divided again into two categories; programmatic planning and the usage planning during the period. This categorization could provide a frame to look into his architecture, through which his projects showed the limitation in modern architecture and the possibility for contemporary architecture.

  • This paper presents a design methodology of high-temperature superconducting (HTS) magnets. The magnet consists of several double pancake coils with a variety of wire width. This technique, named Multi-Width, is well known to make efficient use of the superconducting wire. It is common for design of high-temperature superconducting magnets to not only reduce wire consumption used, but also consider the homogeneity of the magnetic field. In this paper, we study a design method that efficiently reduces wire usage while considering magnetic field homogeneity. The design is carried out by calculating the critical current and the critical magnetic field according to the configuration of arranging the thickness of the wire to determine the number of windings. The width of wire comprising the magnet was set to 4 - 12 mm, and the number of double pancake coils was set to an even number to consist of top-down symmetry. To verify the validity of the design, we compared the progress of the design code with a complete enumeration survey. As a case study, we designed a magnet that generates a central magnetic field of 3 T or more in a 240 mm bore in diameter. Optimality can be evaluated by weighing wire consumption and field homogeneity according to the magnet's use or user preference.

  • All of the subjects of the investigation (n=141) were schools that have food services under direct management. The number of students who get food services at the schools were $1,001{\sim}1,500$ students with 46.8% investigation. In school food services, fried foods were highly preferred and the biggest merits of fried foods were (in order of highest importance) 'improvement of food services satisfaction'> 'source of calories supply'> 'easiness of cooking process'. Service frequency of fried food were in the order of 'twice a week'> 'three times a week'> 'once a week', and for the factors to decide service frequency of fried food, 'preference leaning on fried food', and 'excessive fat intake' were the most considered. The most considered factors in the case of choosing fried food were 'preference' and 'calories and nutritional value'. For the cautious steps during the frying process, 'keeping after frying' was picked the most, and the reasons were 'lack of containers to keep in appropriate temperature and quality' and 'time consuming'. For preference and service frequency of ingredients in fried foods, 'chicken' and 'pork' were very high. As the result, it was analyzed that preference by ingredients matched service in school lunches by using a ranking test. Total cooking and processing time of fried foods required in school lunches were approximately $237{\pm}99$ minutes ${\sim}291{\pm}141$ minutes which showed total required time was about same no matter what ingredients were used. As the result of comparing and analyzing the processes, vegetables took less thawing and frying time, but the processing time for vegetables was more complicated since handling time before frying was longer compared to meat. In the important management process by the main groups of fried foods, the frying process was the most cautious cooking process in the category of meat or fish and shellfish used as ingredients. In addition, if vegetables were used as ingredients, storing it after frying was the process that needed the most care.

  • This study examined the satisfaction of a school milk program as well as the preference of school milk and flavored milk. The subjects of this study were $4^{th}$ , $5^{th}$ and $6^{th}$ grade students in 4 different elementary schools, who were attending the school milk program in Ulsan. The survey was conducted from April 10, 2009 to April 30, 2009. Of the 403 questionnaires distributed, 347 responded and analyzed (usage rate: 86%). The results were as follows. Of the 347 respondents, 53.9% were boys and 46.1% were girls. 34%, 31.1% and 34.9% of the students were $4^{th}$, $5^{th}$ and $6^{th}$ graders, respectively. Second, 80.1% of the students reported 'have milk everyday', and 89.9% of the students reported 'have milk as it is'. Third, the overall satisfaction with the school milk program was 3.32 based on a 5-point likert scale, the 'guidance of nutrition teachers and class teacher' was 3.21 and 'taste of school milk' was 3.37. There were significant positive correlations between the school milk satisfaction variables and overall satisfaction (p<0.01). Fourth, the preference for school milk was 3.33. The preference for flavored-milk were 3.63 (coffee milk), 4.44 (chocolate milk), 4.16 (strawberry milk), 4.26 (banana milk) and 3.53 (black bean milk). Fifth, to improve the school milk program, 85.9% of students wanted a provision for flavored milk. In conclusion, schools need to find a way to increase the satisfaction of the school milk program and the preference of school milk to increase the milk intake of students. Nutrition education for students and parents should be conducted systematically and choices for various kinds of milk and milk products should be given to the students.

  • The electronic toll collection system(ETCS), is globally used in about 40 countries. In Korea, the Korea Expressway Corporation led the nationwide introduction of the ETC system in 2007 under the brand name of the Hi-pass. Since then, Hi-pass, with its rate of average daily use reaching about 70%, has become an essential facility in Korean expressways. To identify users' perception on Hi-pass (satisfaction, preference, etc.), this study conducted a Modified Importance-Performance Analysis (M-IPA). With this, this study attempted to identify the kind of efforts necessary to enhance current Hi-pass users' convenience and satisfaction. According to the result of M-IPA, the items including "non-stop payment" and "toll discount" are identified as key items that require further improvement. For improvement in the "non-stop payment" item, operations of Hi-pass toll booths appropriate for the demand for Hi-pass use and the selection of Hi-pass booths' locations in consideration of entry and exit lanes need to be improved. In addition, with regard to the "toll discount" item, although toll discount is currently provided to Hi-pass users, thus, PR thereof will have to be strengthened. It is expected that this study will be used as basic data to devise methods of enhancing Hi-pass usage through improvement of Hi-pass users' satisfaction.

  • Despite a dramatic increase in the use of smartphones these days, the elderly's smartphone usage rate is relatively low. This is because there are some facts limiting the elderly's access to the smartphones: 1) aging in both physical and cognitive abilities and 2) complicated functions that are hard to see in the phones. In this study, we studied how Korean typography influence the elderly's legibility and extracted proper Korean typography factors that would best suit the elderly when they use the smartphones. As a result of the study and legibility evaluation for the 24 seniors over 65, we could witness the excellence of 13pt font size compared to 11 or 12 and the Serif typeface as being better than San Serif typeface. On the other hand, the space between the letters and lines did not make a big influence on the elderly's readability. From the preference evaluation, there were no differences found between Serif typeface and San Serif typeface. However, a bigger font size was preferred in the order of 13pt, 12pt, and 11pt. There was no difference in preference found regarding the space between the letters and the lines. We expect that proper Korean typography in smartphones could help the elderly in using the smartphones well.

  • The amount of information on the Web is explosively growing as the Internet gains in popularity. However, only a small portion of the information on the Web is truly relevant or useful to the user. Thus, offering suitable information according to user demand is an important subject in information retrieval. In e-commerce, the recommender system is essential to revitalize commercial transactions, raise user satisfaction and loyalty towards the information provider. The existing recommender systems are mostly based on user data collected at servers, so user data are dispersed over several servers. Therefore, web servers that lack sufficient user behavior data cannot easily infer user preferences. Also, if the user visits the server infrequently, it may be hard to reflect the dynamically changing user's interest. This paper proposes a novel personalization system analyzing the user preference based on web documents that are accessed by the user on a user device. The system also identifies non-content blocks appearing repeatedly in the dynamically generated web documents, and adds weight to the keywords extracted from the hyperlink sentence selected by the user. Therefore, the system establishes at an early stage recommendation strategies for the web server that has little user data. Also, user profiles are generated rapidly and more accurately by identifying the information blocks. In order to evaluate the proposed system, this study collected web data and purchase history from users who have current purchase activity. Then, we computed the similarity between purchase data and the user profile. We confirm the accuracy of the generated user profile since the web page containing the purchased item has higher correlation than other item pages.

  • It becomes a common feature of business practices in International Trade to use a standard terms for the formation of their contracts. However, because of differences in legal systems, business practices and so on in their own countries, there have been many conflicts and disputes happening between parties concerned in International Trade. The CISG, which has long been used as the governing law in many cases of International Trade, could not be free from those conflicting issues in its usage and application. This study analyzes the "Black Letter Rules" which was adopted by CISG Advisory Council in 2013 to provide an effective way of resolving the conflicting issues regarding the inclusion of standard terms in International Trade Contracts under the CISG. This study scrutinizes, the relevant rules and requirements for the inclusion of standard terms into a contract. It also deals with the offeror's duty of making clear reference to the standard terms, transmitting the contents of standard terms to the other party. As the other rules for the inclusion of standard terms, this study reviews the principle of denying the inclusion of standard terms after the formation of contracts, exclusion of surprising or unusual terms, preference of individually negotiated terms to the standard terms, contra preferentum rule and preference of the "knock-out rule" to "last-shot rule" in resolving the issue of so called, "Battle of Forms." Lastly, on the basis of analyzed opinion, this study suggests the practical implications for the people working at International Trade-related business sector to facilitate International Trade.
