Predicting protein loop structures is an important modeling problem since protein loops are often involved in diverse biological functions by participating in enzyme active sites, ligand binding sites, etc. However, loop structure prediction is difficult even when structures of homologous proteins are known due to large sequence and structure variability among loops of homologous proteins. Therefore, an ab initio approach is necessary to solve loop modeling problems. One of the difficulties in the development of ab initio loop modeling method is to derive an accurate scoring function that closely approximates the true free energy function. In particular, entropy as well as energy contribution have to be considered adequately for loops because loops tend to be flexible compared to other parts of protein. In this study, the contribution of conformational entropy is considered in scoring loop conformations by employing "colony energy" which was previously proposed to estimate the free energy for an ensemble of conformations. Loop conformations were generated by using two EDISON_Chem programs GalaxyFill and GalaxySC, and colony energy was designed for this sampling by tuning relevant parameters. On a test set of 40 loops, the accuracy of predicted loop structure improved on average by scoring with the colony energy compared to scoring by energy alone. In addition, high correlation between colony energy and deviation from the native structure suggested that more extensive sampling can further improve the prediction accuracy. In another test on 6 ligand-binding loops that show conformational changes by ligand binding, both ligand-free and ligand-bound states could be identified by using colony energy when no information on the ligand-bound conformation is used.

This research defines research support service, and compares the support service provided by college libraries in Korea and overseas. The findings showed that the frequency of college library service in Korean schools were low. Korean college libraries' services were mostly limited to the services of a normal library such as bibliographic education, full text service, and interlibrary loan service. To put it differently, Korean college libraries lacked information services on research ethics. Research spot services per research stage were mostly restricted to the data collection stage, and deficient elsewhere. On the other hand, college libraries in the U.S. were providing a platform for scholarly communication between researcher and scholars via websites.

The Result of this study (1)In the case of KDI school of public policy and management, since it makes up a very interesting and diversified racial environment that shapes the multinational global community, there must be careful considerations for foreign students together with wide publicity about Korea on the side of the school headquarters. (2)The library must become familiar with the ways to utilize outside organizations in order to provide user education to the foreign students. (3)In order to make it perfectly sure for them to provide not only the secondary materials such as bibliography, index, and abstract, but also the necessary full-text from the preparatory stage of the students' studies. (4)The library must grasp the students' needs through communication and must promote the efficiency of library operation by introducing an information service strategy measure similar to that of FISP so they can acknowledge and provide necessary information to fulfill the students' academic needs in advance.

With the help of information technology for a film, characteris both the composition of the story and one of the most important elements that lead the story. Character has a close relationship with personality description, and the character's age, background, education, and occupation help decide his or her personality. Charades are important in that by describing a character's psychology using charade techniques, it gives a stronger impression than by describing with merely lines or narration. When a man's thought changes, their behavior changes; when a behavior is repeated, it becomes habit; when a habit is repeated, it becomes nature. The nature is the person's personality, otherwise called character. Therefore, charade techniques describe a character's psychology well, and consequently, it has maintained its importance. Because human nature and in-depth psychological description have a connection with a character's personality development, I would like to discuss the topic through this research. By using Director Shunji Iwai's "April Story" as the text, the effects of charade techniques on a character's personality development in film will be analyzed by seeking and presenting the methodology shown within the work through charade-acting techniques used by the characters for the development of character's personality.

This study examines the supervision competence of supervisor from the comparative perspective of supervisor and supervisee, and investigates the effects of organizational factors on supervisor's supervision competence. For this purpose, data collected from 241 workers at social welfare agencies in Gyeonggi-do were analyzed through t-test and hierarchical regression analysis. The major results of data analysis are as follows. First, supervisors are more positive than supervisees in terms of supervision competence. Second, there is a statistically significant difference between two groups in supervision knowledge and qualities among the subfields of supervision competence. Third, in the case of supervisors, the younger the age and the higher the education level, the more positively they perceive their supervision competence, and agency's supervision support explains supervision competence at the level of △R² = .305 at p> .001. Finally, based on the results of this study, the directions for strengthening the supervision competence were suggested.

This work is about the development of jet-fuel resistant PVC sealant using a polyester plasticizer. PVC copolymer was compounded with adipic acid glycol(Songcizer P-3000) or DOP plasticizers. Fuel-immersed and non-immersed penetration, solubility, flow, and elongation by tensile adhesion of PVC compounds were measured. Penetration increase by fuel immersion and solubility of PVC compounds with adipic acid glycol polyester plasticizer were smaller than those of PVC compounds with DOP plasticizer. Elongation by tensile adhesion test of PVC compound containing 500 phr of Songcizer P-3000 decreased proportionally to the content of DCDP (dicyclopentadiene) base petroleum resin adhesion promoter. Calcium carbonate($CaCO_3$) filler inhibited the diffusion of fuel in all the PVC compounds and decreased the solubility of PVC compounds containing Songcizer P-3000.

Ethyl-branched polyethylene[PE(2)] containing 2mole% ethyl branch and three ethylene-propylene rubbers(EPR's) haying the same ethylene(E)-propylene(P) molar ratio(E/P=50/50) with different stereoregularity, that is, random EPR(r-EPR), alternating-EPR(alt-FPR) and isotactic-alternating-EPR(iso-alt-EPR) were mixed for the investigation of their properties depending on the stereoregurarity. The three blends were immiscible at room temperature, and showed the simple additivity effect in density behavior. The melting point depression with blend composition increased in order of PE(2)/r-EPR>PE(2)/alt-EPR>PE(2)/iso-alt-EPR. In the tensile test, this blend systems have the lowest value or the breaking strength at FE(2) fraction of 0.5. This phenomenon results from the greastest separated phase morphology at this blend composition.

The purpose of this study is to examine if entrepreneurship that can influence entrepreneurial intention affects job-getting possibility. Particularly, this author has questingly investigated if the entrepreneurship of undergraduates who are supposed to get a job influences job-getting possibility and if sex has regulating effects on job-getting possibility. According to the results, first, undergraduates' entrepreneurship influences job-getting possibility. Second, according to sex, there is difference found in the effects of entrepreneurship on job-seeking skills and job-getting possibility. In other words, sex has significant regulating effects on job-seeking skills and job-getting possibility. Third, according to the results of comparing the mean values of two groups, upper and lower groups of entrepreneurship, regarding their job-getting possibility(work ethic, occupational exploration, & job-seeking skills) in accordance with moderating variables, female undergraduates gained significantly higher mean values than male undergraduates. Based on the results, this author suggests implications and presents proposals for follow-up research.

Augmented Reality(AR) assists human's cognitive ability through the information visualization by substantiating information about virtual situation. This technology is studied in a variety of ways including education, design, industry, and so on, by various supply of information devices equipped with cameras and display monitors. Since the most of the AR system depends on limited interaction that responds to the order from user, it can not reflect diverse real world situation. In this study, we suggest a knowledge based augmented reality system, which is composed of context awareness agent that provides recognized context information, along with knowledge based component that provides intelligent capability by utilizing domain knowledges. With this capability, the augmented object can generate dynamic model intelligently by reflecting context information, and can make the interaction possible among the multiple objects. We developed rule based context awareness system along with 3D model generation, and tested interaction among the augmented objects. And we suggest a framework that can provide a convenient way of developing augmented reality system for user.
