In this study, the effect of communication with a guardian of a recipient of a Long-term Care Program on job satisfaction of care helpers of in-home care facilities for the elderly is analyzed. First, most of the care helpers are content with their job despite low pay and short work-hour. Especially, they are aware of the need of communication with a guardian but skeptical about the need of having intimacy with a guardian, so the relation between a care helper and a guardian is usually formal only. Second, in terms of characteristics of a guardian, care helpers have higher job satisfaction when a guardian is a male and old, and does not have an unreasonable demand. Third, they have higher job satisfaction when they have better communicate with a guardian rather than higher intimacy. Considering this result, we should make programs such as education for a guardian to develop intimacy with a care helper and one for a care helper to develop intimacy and communicate effectively with a guardian. It is also needed to have guidelines which set up relationship between a helper and a guardian.

The problem-based storytelling of the three-act structure, which sees the plot of the story as a solution to the problem of the character, has been the guide of creation to the creator of popular stories since Aristotle. Also problem-based storytelling has served as a schema that provides dramatic catharsis to the audience of the story, and one of the dramatic catharsis It has been working as a schema. This problem - based storytelling has been used as a structure for story production programs that have been developed since the 1980s. However, this story authoring program is focused only on the external problem of the story, but it has the limitation of producing the story that can not solve the internal problem of the character and provide the catharsis. This paper analyze the plot structure of 'StoryHelper', which is a domestic story authoring program, and the ending of 900 films, both domestic and foreign, which are database in 'StoryHelper'. 'StoryHelper' presents a problem-based plot structure that can consider not only external problems but also internal problems by applying causality and mythical episodes. The structure of these plots is based on the parameters of external problem solving, unresolved internal problem solving, and unresolved variables maturity plot(542films), disillusion plot(111films), education plot(132films), tragedy plot(205films). The results of this analysis are expected to provide a meaningful structure for plot-based creative and creative program development.

Unique and invariant biometric characteristics have been used for secure user authentication. Storing original biometric data is not acceptable due to privacy and security concerns of biometric technology. In order to enhance the security of the biometric data, the cancelable biometrics was introduced. Using revocable and non-invertible transformation, the cancelable biometrics can provide a way of more secure biometric authentication. In this paper, we present a new cancelable bits extraction method for the facial data. For the feature extraction, the Subpattern-based Principle Component Analysis (PCA) is adopted. The Subpattern-based PCA divides a whole image into a set of partitioned subpatterns and extracts principle components from each subpattern area. The feature extracted by using Subpattern-based PCA is discretized with a helper data based method. The elements of the obtained bits are evaluated and ordered according to a measure based on the fisher criterion. Finally, the most discriminative bits are chosen as the biometric bits string and used for authentication of each identity. Even if the generated bits string is compromised, new bits string can be generated simply by changing the helper data. Because, the helper data utilizes partial information of the feature, the proposed method does not reveal privacy sensitive biometric information of the user. For a security evaluation of the proposed method, a scenario in which the helper is compromised by an adversary is also considered.

Periodontal disease research has been focused on understanding the immunopathologic mechanisms which may operate in the development and maintenance of peiodontal inflammatory changes. Immunologic and inflammatory responses may relate to the etiology and pathogenesis of periodontal disease. In order to research immunopathology of periodontal disease, previous investigators have spent much time on the distribution of lymphocyte subpopulations and NK cells but they have spent less time on the changes of those cells to the periodontal disease severity. The purpose of study was performed to investigate the changes of the distribution of T lymphocytes, B lymphocytes, T lymphocyte subsets, and Natural Killer cells in the gingival epithelium and connective tissue of the periodontal disease with the various clinical parameters including Gingival Index, Sulcular Bleeding Index, and pocket depth. Gingival tissues were obtained from 25 patients with different severity of periodontal disease. Serial cryostat sections displaying a cross section of gingiva were labelled with monoclonal antibody for pan T cells, T cytotoxic/suppressor cells, T helper/inducer cells, pan B cells, and NK cells were develped using an avidin-biotin-peroxidase system. Lymphocyte populations were enumerated in repeatable fields from gingival section. 1. T cells were more increased at grade 1 and 3 than at grade 0 of gingival index (p<0.05). Helper T cells and NK cells were significantly increased at grade 1, 2, 3 than at grade 0(p<0.05). 2. T cells were more decreased at grade 3 and 4 than at grade 1 of sulcular bleeding index (p<0.01, p<0.05). Especially, Natural Killer cells were significantly increased at grade 1, 2, 3, 4 than at grade 0 (p<0.05, p<0.001). 3. The ratios of helper T/suppressor T cells were more decreased at grade 4 than at grade 0 and at grade 4 than at grade 2 of sulcular bleeding index (p<0.05, p<0.05). 4. Helper T cells were significantly decreased at grade II and III than at grade I, however the Natural Killer cells showed a increasing tendency with the increase of the pocket depth, there were no significant differences between each grade of pocket depth. 5. The ratios of helper T/suppressor T cells were tended to be decreased with the increase of the pocket depth, there were no significant differences between each grades of pocket depth. There was a very weak change in the distribution of T lymphocytes, B lymphocytes, T lymphocyte subsets, and Natural Killer cells in the gingival epithelium and connective tissue of the periodontal lesion with the various clinical parameters including gingial index, sulcular bleeding index, and pocket depth. But, the number of T lymphocytes and Natural Killer cells were significantly changed in gingival index and sulcular bleeding index.

With the advent of distributed computing and Web service technologies, lots of users have been requiring services that can conveniently obtain and/or support well-assembled information based on Web. For this reason, we are to construct Automatic Linking Support Systems for generating Web-based integrated information and supporting retrieval information according to user's various requirements. Our system organization is based on client/server system. A server environment consisted of automatic linking engine that can provide lexical analyzing, query processing and integrated document generating functions, and databases that are made of dictionaries, image and URL contents. Also, client environments consisted of Web editor that can generate integrated documents and Web helper that can retrieve them via automatic linking engine and databases. For client's user-friendly interfaces, web editor and helper programs can directly execute by down leading from a server without setup them before inside clients. For reducing server's overheads, Parts of server's executing modules are distributed to clients on which they can be executing. As an implementation of our system, we use the JDK 1.3, SWING for user interfaces like Web editor and helper, RMI mechanism for interaction between clients and a server, and SQL server 7.0 for database development, respectively. Finally, we showed the access procedures of automatic document linking engine and databases from Web editor or Web helper, and results appearing on their screens.

Identifying characters who appear in a story and analyzing their relationships is essential to understanding the story. This paper aims to identify the two actants (or character roles) as Helper and Opponent in Greimas's Actantial model by identifying Subject (i.e., protagonist) and analyzing the emotional interactions between the Subject and the two actants (Helper/Opponent). Our proposed method consists of three steps. First, we identify objects (i.e., characters) appearing in the text story. Next, we extract relational information through the interaction of the characters, and then classify emotions in the text expressed as relational information. Finally, we represent the flow of emotional relations among characters as a directed graph. The node with the highest degree is considered as the Subject because it includes the most relational information. The node that sends the most positive/negative emotions to the Subject is considered as the Helper/Oppenent, respectively. Our research contributes to the computer-based narrative understanding by providing a computational method that automatically extracts the three key character roles (Subject, Helper, and Opponent) from the text story.

CD28/T cell receptor ligation activates the NF-${\kappa}B$ signaling cascade during CD4 T cell activation. NF-${\kappa}B$ activation is required for cytokine gene expression and activated T cell survival and proliferation. Recently, many reports showed that NF-${\kappa}B$ activation is also involved in T helper (Th) cell differentiation including Th17 cell differentiation. In this review, we discuss the current literature on NF-${\kappa}B$ activation pathway and its effect on Th17 cell differentiation.
