  • 이 연구는 대만의 공공도서관 역사와 현황을 살펴보기 위한 것이다. 1901년 대만문고를 일본 거류민이 설립함으로써 시작된 대만 공공도서관의 역사는 대만총독부도서관 설립으로 본격화되었다. 광복과 중화민국 정부의 대만천도 이후 침체를 겪다가 1979년 '문화건설계획' 이후 양적으로 늘어나고, 1987년 계엄령 해제로 출판물이 증가하면서 질적으로도 발전하게 되었다. 이후 급격히 발전한 대만 공공도서관의 현황을 통해 공립공공 도서관이 발전의 주축이 되고 있다는 점, 국가도서관뿐만 아니라 주요 공공도서관 관장이 도서관전문가라는 점, 현장에서의 연구가 활발하다는 점, 도서관의 독서진흥활동이 성인독자, 노인독자 등 연령대를 폭넓게하여 이루어진다는 점, 도서관간의 상호협력, 녹색도서관건축에 대한 관심이 커지고 있다는 점 등의 장점을 발견하였다.

  • The purpose of this study is ; 1) to identify the overall levels of family problem and stress perceived by urban homemakers, 2) to investigate the relations between them. For the purpose of this study, the samples were chosen among 369 homemakers living in Seoul. These data were analyzed by Frequency, mean, t-test, F-test, Duncan's Multiple Rang test and pearson's correlation. The significant results are as follows : 1) urban homemakers perceive 'economic problem' as the highest level, 'children problem' as the second one and 'health problem' as the lowest one in family life problem. There is significant difference in family problem perception according to education level, husband's job, children's numbers, and living level. 2) There is not sigificant difference in stress level according to independence variables. 3) There are positive correlations between the family problem perception and stress level of urban homemakers. In conclusion, we come to know every field of family life effects homemakers as stressors. According, it is necessary for us to understand and prevent family life problem in order to release stress perceived by homemakers.

  • If additional condition in letter of credit is used in malicious way, it affects the international trade transaction in jeopardy. Therefore, it's significant to identify whether additional conditions are malicious or ordinary in the transaction with letter of credit. In normal cases, thanks to lots of useful features as an international payment method, such as security of payment, legal protection, and versatility, a letter of credit is widely used in international trade. However, even with these advantageous features, a letter of credit is complicate and costly to use, compared to other payment methods. Furthermore, due to its principle of independence from underlying contract, a use of letter of credit creates another type of concern for proper handling and needs significant caution upon field use. At some points, malicious additional conditions are used for buyer's advantage in deal making and fraud instance in worst situation. In addition, some countries request malicious conditions against sellers as a non-tariff barrier. Therefore it's extremely important to recognize whether malicious additional condition exists in letter of credit and, if so, how to deal with it. This study delivers the information to distinguish and categorize the malicious conditions in various cases and to figure out how to deal with them for safer trade with less risk.

  • The bootstrap is a method of computational inference that simulates the creation of new data by resampling from a single data set. We propose a new job for the bootstrap: generating inputs from one historical trace using Threshold Bootstrap. In this regard, the most important quality of bootstrap samples is that they be functionally indistinguishable from independent samples of the same stochastic process. We describe a quantitative measure of difference between two time series, and demonstrate the sensitivity of this measure for discriminating between two data generating processes. Utilizing this distance measure for the task of generating inputs, we show a way of tuning the bootstrap using a single observed trace. This application of the threshold bootstrap will be a powerful tool for Monte Carlo simulation. Monte Carlo simulation analysis relies on built-in input generators. These generators make unrealistic assumptions about independence and marginal distributions. The alternative source of inputs, historical trace data, though realistic by definition, provides only a single input stream for simulation. One benefit of our method would be expanding the number of inputs achieving reality by driving system models with actual historical input series. Another benefit might be the automatic generation of lifelike scenarios for the field of finance.

  • This paper describes a new magnetization method for non-destructive testing with magneto-optical sensor (denoted as MO sensor) which have the following characteristic : high observation sensitivity, independence of the crack orientation, and precise imaging of a complex crack geometry such as multiple cracks. When a magnetic field is applied normally to the surface of a specimen which is significantly larger than its defects, approximately the same magnetic charge per unit area occurs on the surface of the specimen. If there is a crack in the specimen, magnetic charge per unit area has the same value at the bottom of the crack. The distribution of the vertical component of the magnetic flux density, B$\_$Z/, is almost uniform over the no-crack area (denoted as B$\_$Z,BASE/), while the magnetic flux density is smaller in the surroundings of the crack(denoted as B$\_$Z,CRACK/) If B$\_$Z, BASE/ is a bit larger than the saturated magnetic flux density of the MO sensor (B$\_$s/) , then small magnetic domains occur over the crack area and a large domain over the non-crack area because B$\_$Z,CRACK/ is smaller than B$\_$s/.

  • Purpose: The purpose of the study was to describe the parenting experience of parents of children with chronic illness in Korea. Methods: A conventional contents analysis was used for the study. Twelve mothers of chronically ill children participated in the study. Qualitative data were analyzed using the Morse and Field method. Results: Four categories, 10 subcategories and 42 codes emerged from the data on the parenting experience of parents of children with chronic illness. The four categories were 'Sacrifice and full-engagement within self-mortification', 'Re-normalization of collapsed daily life', 'Paving a new way for independence' and 'Growing together of myself and the family'. Conclusion: Parents of children with chronic illness experienced not only negative aspects such as a confusion but also re-normalization and growing together. Based on the results, health professionals need to develop effective nursing interventions toward positive parenting for these parents and their children with chronic illnesses.

  • By using numerical simulation, vast and detailed information and observation of the physics of flow over a train model can be obtained. However, the accuracy of the numerical results is questionable as it is affected by grid convergence error. This paper describes a systematic method of computational grid refinement for the Unsteady Reynolds Navier-Stokes (URANS) of flow around a generic model of trains using the OpenFOAM software. The sensitivity of the computed flow field on different mesh resolutions is investigated in this paper. This involves solutions on three different grid refinements, namely fine, medium, and coarse grids to investigate the effect of grid dependency. The level of grid independence is evaluated using a form of Richardson extrapolation and Grid Convergence Index (GCI). This is done by comparing the GCI results of various parameters between different levels of mesh resolutions. In this study, monotonic convergence criteria were achieved, indicating that the grid convergence error was progressively reduced. The fine grid resolution's GCI value was less than 1%. The results from a simulation of the finest grid resolution, which includes pressure coefficient, drag coefficient and flow visualization, are presented and compared to previous available data.

  • This work proposes a model to solve the problem of Network Coding over a one-session multicast network. The model is based on a system of restrictions that defines the packet flows received in the sink nodes as functions of the outgoing flows from the source node. A multicast network graph is used to derive a directed labeled line graph (DLLG). The successive powers of the DLLG adjacency matrix to the convergence in the null matrix permits the construction of the jump matrix Source-Sinks. In its reduced form, this shows the dependency of the incoming flows in the sink nodes as a function of the outgoing flows in the source node. The emerging packets for each outgoing link from the source node are marked with a tag that is a linear combination of variables that corresponds to powers of two. Restrictions are built based on the dependence of the outgoing and incoming flows and the packet tags as variables. The linear independence of the incoming flows to the sink nodes is mandatory. The method is novel because the solution is independent of the Galois field size where the packet contents are defined.
