  • As the wireless communication technology developed, the Electric Commerce using a mobile was activated. WPKI was developed in order to guarantee the stability of the Electric Commerce but it is difficult to be ensured for the safe PKI service which is the same at the wire communication in the technical because of restriction of the mobile terminal. In this paper, we propose the authentication system for the electronic financial service which is safe and is effective in consideration of the restrictive characteristic of the mobile terminal. Moreover, the encryption algorithm for the safe electronic signature is proposed. In WPKI, this makes the cross certification of each certificate authority possible. Moreover, a stability was enhanced through the signature authentication using KCDSA and SEED algorithm.

  • Objective : This study is to investigate the method for assesment and diagnosis of ADHD, especially focusing on behavior rating scales. Methods : We searched the recent date of the publication and paper in ADHD. Results : For Assesment and Diagnosis of ADHD, various method such as interview with parents, child and teacher, behavior observation, behavior rating scales and neuropsychological test are used. The structured interview consists of the restrictive questions and response, and then have diagnostic algorithm, consequently can be used by untrained clinicians. Of the structured interview, standardization of K-SADS in Korean version is finished. Behavior rating scales, the form of parent, teacher and self-report questionnaires, are used as diagnosis and treatment evaluation of ADHD. Behavior rating scales consist of both ADHD-specific scales and broad-band scales designed to screen for various symptoms (including ADHD symptoms). ADHD-specific scales are useful in differential diagnosis, discrimination of subtype, treatment evaluation, However, broad-band scales are useful in preliminary examination. The neuropsychological tests can evaluate attention deficit and effect of attention deficit on cognitive function and academic performance. The neuropsychological tests also used in diagnosis and treatment evaluation of ADHD. Conclusion : For Assesment and Diagnosis of ADHD, various method are used, especially behavior rating scales are both useful and simple tool for diagnosis and treatment evaluation.

  • With the advent and popularity of e-commerce, an increasing number of consumers prefer to order tourism products online. A recommender system can help these users contend with information overload; however, such a system is affected by the cold start problem. Online tourism destination searching is a more difficult task than others on account of its more restrictive factors. In this paper, we therefore propose a tourism destination recommender system that employs opinion-mining technology to refine user preferences and item opinion reputations. These elements are then fused into a hybrid collaborative filtering method by combining user- and item-based collaborative filtering approaches. Meanwhile, we embed an artificial interactive module in our recommender system to alleviate the cold start problem. Compared with several well-known cold start recommendation approaches, our method provides improved recommendation accuracy and quality. A series of experimental evaluations using a publicly available dataset demonstrate that the proposed recommender system outperforms existing recommender systems in addressing the cold start problem.

  • A patient,58 years of age, with suspected 0/l pneumoconiosis since 1993, complained of a dry cough and exertioning dyspnea for 6 months. He had worked in an asbestos company for more than 20 years from 1974. He was subsequently diagnosed with an interstitial lung disease during an annual special health check-up for asbestos workers. h chest X-ray showed an interstitial lung disease and high-resolution computed tomography (HRCT) showed a round opaque asbestosis with chronic hypersensitivity pneumonitis. A pulmonary function test indicated that the patient had a mild restrictive lung disease with FEV1 1.67 litters and 82% FEVl/FVC. The bronchoalveloar larvage fluid included many asbestos bodies, indicating previous exposure to asbestos. Transmission electron microscopy (TEM) using an energy dispersive X-ray analyzer (EDX) revealed many asbestos bodies consisting of mainly crocidolite fibers (6,071$\times$$10^6$fibers/g of dry lung). The patient had an unusually high asbestos content of 6,112$\times$$10^6$ asbestos fibers/9 of dry lung.

  • The temperature sensitive (ts) mutation on RNA1 gene of Saccharomyces cerevisiae prevents growth at restrictive temperature ($36^{\circ}C$) by accumulation of precursor tRNA, rRNA and mRNA (Hutchison et al., 1969; Shiokawa and Pogo, 1974; Hopper et al., 1978). RNA1 gene was cloned by complementation of the temperature sensitive growth defect of an rna1-1 mutant strain and identified by retransformation and concomitant loss of recombinant plasmid on non-selective condition. By deletion mapping, it was found that RNA1 gene resides within 3.5kb of BgII fragment.

  • In budding yeast, G2/M transition is tightly correlated with bud morphogenesis regulated by Swel and septin that plays as a scaffold to recruits protein components. BNI5 isolated as a suppressor for septin defect is implicated in septin organization and cytokinesis. The mechanism by which Bni5 regulates normal septin function is not completely understood. Here, we show that Bni5 phosphorylation is required for mitotic entry regulated by Swel pathway. Bni5 modification was evident from late mitosis to G1 phase, and CIP treatment in vitro of affinity-purified Bni5 removed the modification, indicative of phosphorylation on Bni5. The phosphorylation-deficient mutant of BNI5 (bni5-4A) was defective in both growth at semi-restrictive temperature and suppression of septin defect. Loss of Bni5 phosphorylation resulted in abnormal bud morphology and cell cycle delay at G2 phase, as evidenced by the formation of elongated cells with multinuclei. However, deletion of Swel completely eliminated the elongated-bud phenotypes of both bni5 deletion and bni5-4A mutants. These results suggest that the bud morphogenesis and mitotic entry are positively regulated by phosphorylation-dependent function of Bni5 which is under the control of Swel morphogenesis pathway.

  • The objectives of this study were to examine the utilization patterns of oriental medical care and to discover problems in its delivery. The data for this study were collected from a questionnaire survey mailed out from March 10 to April 9 1999 to 6.346 oriental medical clinic. The questionnaires were then distributed to two patients in each clinics. Of these questionnaires. 670 were completed and returned. The major statistical methods used for the analysis were the t-test. ANOVA, and x$^2$-test. The major findings are as follows: 1. Respondents reported visiting oriental doctors twice as often as they visited western doctors(All those completing the survey received the questionnaire at oriental medical clinics). 2. The number of reported visits to oriental physicians according to among gender, age, marital status, education, income and residence. Males, married respondents, the elderly and the residents of rural areas visited oriental physicians more frequently than females, singles, younger respondents and urbanites. Those people belonging to the middle income class and middle education level also more frequently visited oriental physicians. 3. There are several factors that restrict the utilization of oriental medical care, such as the limitation of the scientific diagnostic instrument use commonplace reliance upon western medical techniques, and the perception of high price for oriental medical care. It is very important to focus oriental medical care onto the fields of acupuncture, circulatory system disease, musculoskeletal system ailments, etc. to improve the utilization of oriental medical care. Other policies for the improvement of oriental medical care include the standardization of price, quality and quantity of oriental medicine.

  • It is the aim of this study to attain general knowledge of Intellectual freedom which provides the philosophical principle of our library activities. Also, this study seeks to develop the principia of intellectual freedom as the policy and guide of public libraries in Korea. In order to research the operational circumstances of intellectual freedom In our public libraries, the researcher visited 20 public libraries in the Seoul district. The results clearly confirmed the self-censorship of the librarians in selecting materials. Also, it confirmed the reality of external interventions and restrictions as well as restrictive sources originating from internal ignorance and habitual practices in our public libraries. Ultimately, such results provided a solid basis for the aim of this study to develop intellectual freedom principle as the basic ideology for public library activities in Korea.

  • A dominant idea is that because virtual members trust one another less than do the non-virtual and therefore the traditional face-to face teams are better than the virtual, the virtual team can be organized to cope with the inevitable, restrictive situation in which they cannot organize a team with face-to-face meetings. However, we believe that even if a manager coping with a certain problem can organize a face-to-face team (evitable situation), there might be some areas or cases in which organizing a virtual team is better than organizing a face-to-face team. This paper suggests it is important for practical managers to identify when(for which situations) the virtual teams are most suitable and can be successful without losing trust.
