This study has a main purpose on discussing the issue how the construction of film narrative will be changed by audience's desire to intervene into film narrative through the active participation, out of watching a film passively in movie theater. Compared with the collective theatergoing experience in big screen was defined as the past cinematic identity, the absolute value of movie theater fragmented increasingly in the era of media diversification facing with digital media convergence. As this situation can be compared with "the author's death" Roland Barthes predicted on the mono-media of the book, thus, we are to take the time to discuss the new emerging 'movies'. The most important thing in this discussion is the aspect of the transformation of narrative in the future screening. Especially, while 3 act structure and configuration evoking a catharsis in film narrative are elements defining aspect of the past narrative, then, the future narrative in film will change to the structure interacting with audience actively. This paper had a discussion how could be possible the aucience interaction in only movie valuing the passive experientiality uniquely in screening over the other media through investigating the attempts of interactive cinema so far and the possibility of future.

The main purpose of this paper is to investigate the factors which affect the alienation of the aged, and to study the relative importance of these factors. This study focused on the following research questions: 1) How do the demographic variables(sex, marital status, family structure, religion, economics, prior occupation, education level) affect the alienation of the aged? 2) How the alienation of the aged is affected by their involvement in social activities? 3) Does the degree of satisfaction with family relationship have a perceivable impact on the alienation of the aged? 4) How does the self-rated senescence affect the alienation of the aged? The research was practiced from the 18th Sept. 1999 to the 30th Sept. 1988, through individual interviews with 300 elderly people, all living in Seoul area. Among them only 285 were used in the analysis. The major findings of the study are as follows; 1) The sex of the respondents makes no difference in the alienation of the age . 2) Marital status is found to be relatively significant in determining the alienation. The degree of alienation of old people with spouse is substantially lower than that of those without spouse. 3) Family structure was found to have no significantly effect on the alienation of the aged. 4) Involvement in religion was found to significantly reduce the alienation of the aged. 5) Econimic factors seems to be critical in defermining the aged. The amount of pocket money avaliable for daily use has direct relationship with alienation. 6) Prior occupation was found to be another significant factor affecting alienation professionals experience far lower alienation than nonprofessionals. 7) The higher is education level, the lower is the alienation of the aged. 8) Active participation in social activities and good relationship with other family members were founded to contribute to lowering the alienation of the aged. Whereas, too much concern over one's senescence appears to hav negative effects on the alienation. The regression analysis shows that the satisfaction with the family relationship has the most important influence upon the alienation of the aged. Following are the factors of self-rated senescence, pocket money in a descending order. All these factors, which explain 42.65% of the total variance of alienation variable are statistically significant(p<.001)

Objectives : This study evaluated knowledge structure and its effect factor by analysis of co-author and keyword networks in Korea's preventive medicine sector. Methods : The data was extracted from 873 papers listed in the Journal of Preventive Medicine and Public Health, and was transformed into a co-author and keyword matrix where the existence of a 'link' was judged by impact factors calculated by the weight value of the role and rate of author participation. Research achievement was dependent upon the author's status and networking index, as analyzed by neighborhood degree, multidimensional scaling, correspondence analysis, and multiple regression. Results : Co-author networks developed as randomness network in the center of a few high-productivity researchers. In particular, closeness centrality was more developed than degree centrality. Also, power law distribution was discovered in impact factor and research productivity by college affiliation. In multiple regression, the effect of the author's role was significant in both the impact factor calculated by the participatory rate and the number of listed articles. However, the number of listed articles varied by sex. Conclusions : This study shows that the small world phenomenon exists in co-author and keyword networks in a journal, as in citation networks. However, the differentiation of knowledge structure in the field of preventive medicine was relatively restricted by specialization.

Korea is going to the structure of low fertility and aging population, which is so difficult to find a precedent in the world. Furthermore, since population structure is changing to the upside down pyramid type, it acts as a factor that makes the production population matters worse. In this situation, senior's job programme has fixed those problems to a certain extent, but more effective support system should be provided in the respect of economic and social integration. Also efforts should be made for a view to a wide range of job creation and dissemination. Decent jobs can be created in the area of culture, welfare, health care, tourism, by utilizing skills and experience that senior had before they retired. In conclusion, this study provides a theoretical basis for an efficient measure of senior's job programme.

To promote information service and to encourage active participation from the group categorized as the alienated class(group of people) this study suggests the basic concepts and strategy for the information services to alienated class who does not have full public library services. The paper classifies three separate groups of alienated groups, handicapped. poor(economically unfortunate group) and elderly group. The service shall consider their needs from their own Point of concern and interests. There are three distinctive considerations, infra structure(facility building, space. place). administrative consideration, and equipments. Infra-structure includes the planning of the space to facilitate the equipments and reference materials which will be control)ed and moderated by a librarian. Administrative service includes the development for the educational system between the end users and external experts. It also includes the individualized education system for each group Material and equipment consideration should include the each group's specific needs such as the infra-structures which is provided for the handicapped person.

In general, quantitative chemical analysis in various areas including food, the environment, in vitro diagnostics, etc., requires traceability in order to increase the reliability of the measurements. Measurement traceability is a property of an unbroken chain of comparisons relating an instrument's measurements to SI units. Purity analysis is the first process for establishing traceability to SI units in chemical measurements. The purpose of this study is to develop and validate a method of purity assignment for establishing the traceability of $17{\beta}$-estradiol measurements in an in vitro diagnostics field. The establishment of this method is very important as it can be applied to the development of CRM and to the analysis of the purity of other hormones. The method of assignment of the purity of $17{\beta}$-estradiol was developed using the mass balance method and was validated through participation in an International comparison. In the mass balance method, impurities are categorized into four classes as follows: total related structure impurities, water, residual organic solvents, and nonvolatiles/inorganics. In this study, total related structure impurities were characterized by a gas chromatography-flame ionization detector (GC-FID) and a high-performance liquid chromatography-ultraviolet (HPLC-UV) detector, water content was determined by a Karl-Fisher coulometer, and total residual solvents and nonvolatiles/inorganics were checked simultaneously by thermogravimetric analysis (TGA). The purity of the $17{\beta}$-estradiol was 985.6 mg/g and the expanded uncertainty was 2.1 mg/g at 95% confidence. The developed method can be applied to the development of certified reference materials, which play a critical role in traceability.

Deciding on an optimal sensor placement (OSP) is a common problem encountered in many engineering applications and is also a critical issue in the construction and implementation of an effective structural health monitoring (SHM) system. The present study focuses with techniques for selecting optimal sensor locations in a sensor network designed to monitor the health condition of Dalian World Trade Building which is the tallest in the northeast of China. Since the number of degree-of-freedom (DOF) of the building structure is too large, multi-modes should be selected to describe the dynamic behavior of a structural system with sufficient accuracy to allow its health state to be determined effectively. However, it's difficult to accurately distinguish the translational and rotational modes for the flexible structures with closely spaced modes by the modal participation mass ratios. In this paper, a new method of the OSP that computing the mode shape matrix in the weak axis of structure by the simplified multi-DOF system was presented based on the equivalent rigidity parameter identification method. The initial sensor assignment was obtained by the QR-factorization of the structural mode shape matrix. Taking the maximum off-diagonal element of the modal assurance criterion (MAC) matrix as a target function, one more sensor was added each time until the maximum off-diagonal element of the MAC reaches the threshold. Considering the economic factors, the final plan of sensor placement was determined. The numerical example demonstrated the feasibility and effectiveness of the proposed scheme.

The purpose of this study was to confirm that the formation and influencing factors of ocean governance in Busan. Recently it has been observed that the concept of ocean governance increasingly popular in the field of maritime administration, as the concept helps us understand more comprehensively the new or emerging roles of the government and other stakeholders(private enterprise, citizen, etc) in a rapidly changing environments. Therefore, this study aims to investigate the status of ocean governance and draw alternatives in applying appropriate ocean governance structure of maritime administration in Busan. The result of this study shows that ocean governance level in Busan was not high in some factors such as participation, cooperation, collective decision making. This is caused by the lack of a ocean governance structure. Based on these significant research findings, theoretical and practical implications were discussed.

We present the tandem mass spectrometry applications carried out to elucidate the coordination structure of Zn(II) bound lysine ternary complexes, $(Zn+Lys+Lys-H)^+$, which is a good model system to represent a simple (metallo)enzyme-substrate complex (ES). In particular, experimental efforts were focused on revealing the involvement of a lysine side chain ${\varepsilon}$-amino group in the coordination of $Zn^{2+}$ divalent ions. MS/MS fragmentation pattern showed that all the oxygen species within a complex fell off in the form of $H_2O$ in contrast to those of other ternary complexes containing amino acids with simple side chains (4-coordinate geometries, Figure 1a), suggesting that the lysine complexes have different coordination structures from the others. The participation of a lysine basic side chain in the coordination of Zn(II) was experimentally evidenced in MS/MS for $N{\varepsilon}$-Acetyl-L-Lys Zn(II) complexes with acetyl protection groups as well as in MS/MS for the ternary complexes with one $NH_3$ loss, $(Zn+Lys+Lys-NH_3-H)^+$. Detailed structures were predicted using ab initio calculations on $(Zn+Lys+Lys-H)^+$ isomers with 4-, 5-, and 6-coordinate structures. A zwitterionic 4-coordinate complex (Figure 7d) and a 5-coordinate structure with distorted bipyramidal geometry (Figure 7b) are found to be most plausible in terms of energy stability and compatibility with the experimental observations, respectively.

MANET has many security vulnerabilities because it consists of only mobile nodes using wireless. In particular, it is a very important factor determining network performance that excludes the participation of malicious nodes through accurate reliability measurements and authentication of nodes participating in the network. In this paper, we proposed a technique applied with blockchain technology in order to prevent forgery of authentication information for nodes participating in the network. And, an area-based hierarchical structure was applied to increase the efficiency of authentication for nodes and apply the optimal technique of block generation and exchange protocol. In addition, four data payloads were added to the block header in order to add authentication information for nodes in block. To improve the reliability by applying the blockchain technique to the hop-by-hop data transfer method between mobile nodes, blockchain exchange protocol through transaction creation, block packaging and verification processes were implemented. We performed the comparative experiment with the existing methods to evaluate the performance of the proposed method and confirmed the excellent performance by the experiment results.
