Unit Root and Cointegration Tests of Puraching Power Parity in the Pacific Rim

Kim, Jin_ock 제주대학교 1992 논문집 Vol.34 No.1

구매력평가설(Thory of Purchasing Power Parity)에 관한 문헌을 개관하여 보면 구매력평가설이 성립하기 위한 가정의 적합성에 관하여 상당한 논란의 여지가 있음을 알 수 있다. 지금까지 행해진 경험적 분석들은 미국·유럽 및 일본경제에 있어서 구매력 평가설의 성립여부를 검정한 것 들이었다. 이러한 검정결과들은 구매력평가설이 성립하는 것을 옹호하는 편이지만, 그 암묵적 가정은 구매력평가설이 유사한 산업구조를 갖고 있는 국가들 사이에 성립한다는 것이다. 그러나 이러한 가정은 적절하지 못하다. 이러한 관점에서, 한국경제를 주축으로 한 환태평양지역에서 구매력평가설의 성과를 규명코자 시계열분석의 일환인 공적분 검정(Cointegration Test)과 단위근 검정(Unit Root Test)을 하였다. 공적분 검정결과에 의하면 태국을 제외한 국가들(미국, 독일, 일본, 필리핀, 인도)에 있어서 구매력평가설은 성립하지 않았다. 즉 한국경제에 있어서 구매력평가설은 성립하지 않음을 알 수 있다. 전형적인 이론에 의하면, 단기에 있어서 통화공급충격은 구매력평가의 편차를 야기하지만, 장기에 있어서 이러한 편차는 소멸된다. 반면에 실질충격(Oil Shock, 정부지출)은 단기 또는 장기에서 구매력평가의 편차를 야기한다. 따라서 본 논문의 항후 연구과제는 환태평양지역에서 구매력평가설이 성립하지 않음을 이론적으로 재규명하고 동시에 경험적 분석을 하는 데 있다.

Scrambling of Adjunct and Last Resort

Cho, Jai-Hyoung and Kim, Ock-Hwan. 1999. Scrambling of Adjunct and Last Resort. Linguistics 7-$ 39-59. This paper deals with long-distance scrambling of adjuncts in Korean and Japanese with respect to the Last Resort principle. It is claimed that long-distance scrambled arguments are base-generated in the surface non-θ IP-adjoined position and that they must be obligatorily lowered into their θ-position at LF to check their θ-role feature, which is regarded as a movement-driving formal feature. Long-distance scrambled adjuncts are also argued to be base-generated in the IP-adjoined position. Unlike their argument counterparts, they are licensed there since adjuncts do not have any Case or θ-requirement. Thus, they must not be lowered into the embedded clause which they modify, otherwise the Last Resort principle would be violated. (Ajou University)

The purpose of this study is to investigate the interaction of tenoxicam with various cyclodextrins (CDs) in the aqueous solution and in solid state, and finally to formulate a tablet with enhanced dissolution rate. CDs used in solubility studies were α-, β- and γ -CD, 2-hydroxypropyl-β-CD (HPCD), sulfobutyl ether-β-CD (SBCD), dimethyl-β-CD (DMCD) and trimethyl-β-CD (TMCD). The effect of CDs on the solubility of tenoxicam was observed. Solid dispersions were prepared with β-CD using solvent evaporation and freeze-drying process and physical mixtures were prepared by trituration in a mortar. The ratios of drug to carrier were 1:1 and 1:2 molar ratio. These solid dispersions were evaluated by differential scanning calorimetry (DSC), Fourier-transform infrared spectroscopy (FT-IR) and dissolution studies. Solid dispersions were also formulated to tablets and then dissolution rates were compared with that of a commercial product. In aqueous solution, complex formation with α- and β-CD gives rise to Bs type solubility phase diagram, and DMCD, TMCD, HPCD and SBCD showed AL type diagrams. The solubility increase of tenoxicam was in the order of SBCD>γ-CD>β-CD>HPCD>DMCD>α-CD>TMCD. The presence of water soluble polymers such as povidone and hydroxypropyl methylcellulose in β-CD solution did not increase the solubility of tenoxicam. DSC and FT-IR studies confirmed the formation of an solid complex of tenoxicam with β-CD. Dissolution of solid dispersion was about 4-fold higher than that of drug alone and about 2-fold higher than that of physical mixture within 10 min at pH 1.2. As the ratio of carrier to drug increased, dissolution rate became faster. The dissolution rate of tenoxicam from the tablets prepared using freeze-dried solid dispersion at 1:2 molar raio was fast; more than 80% was dissolved within 15 min at pH 1.2. All tenoxicam tablets prepared using tenoxicam-β-CD solid dispersions showed more rapid dissolution rates than commercial tablets. Therefore, the solid dispersion technique is an effective method for increasing the dissolution rate of poorly water soluble tenoxicam. β-CD was thought to be a candidate carrier for preparing solid dispersion with tenoxicam.

정보써어비스의 새로운 추세와 적용문제에 관한 고찰

노옥순 韓國圖書館學會 1986 圖書館學 Vol.13 No.1

The purpose of this article is to take a look into the past twenty years and to evaluate the changes in the organization of the library and the information function during this time period. Academic and special libraries are the ones that have made an impressive progress and innovations to keep pace with a changing environment. New technologies and ideas have brought strong supporters of offering various specialized information services to the library users. The different approaches and experiments to better perform this professional role in the library and in turn, the efforts in the educational institutions to meet the challenges were reviewed through the literature. Much of the literature available regarding the reference and information function deals mainly with the trends in the u.s. libraries. The implications of these trends to Korean libraries and library education are sought in view of our social, economic, and educational circumstances as well as our user behavior

The main intention of this paper is to look into the matters affecting the library that deals with the humanities. Based on comprehensive literature survey and analysis, information needs of scholars in the humanities and the role of the library as an information center are reconsidered in some detail. In fact, the behavioral research on scientists and social scientist in their scholarly communication and use of libraries has long been of interest to those in library and information science field. The research results have implied much on library operations and services. Types of materials acquired, use of subject specialist system, and better secondary services are some of the examples affected by the findings. Similar research efforts on the humanities began to be regularly reported in the 70 's. They treat mainly the difference between the aims, methods and styles of research people in the humanities as distinct from other disciplines. This disparate nature of knowledge and its communication suggests accordingly different approaches in various library policies and decision-making. The subject of this paper, therefore, is not the content of scholarship in the humanities, but information transfer. Special concern is on storage, retrieval and dissemination of information. Library as one of the most important information transfer institution comes naturally in the center of the subject. General characteristics of the humanities studies are observed first. Information needs of the scholars are analyzed along with their communication and research processes in the next section. What follows is the materials they need. These are reviewed in terms of quantity, quality, life span, and other aspects. Outstanding difficulties and problems that the humanities library face are brought out with some suggested ways to improve the situation. Collection management, inter-library cooperation, and secondary services (bibliographies, indexes, abstracts) are areas that still remain to be investigated for improvement.

司書와 圖書館 利用者間의 커뮤니케이션 機能

Human acts and activities generate for the most part information requirements for various needs and purposes. At the moment a man is faced with particular problems, a sense of imperfection, or a certain incompleteness, he will deliberate on formal and informal methods to solve them. He may choose the library or information center as one of several possible alternatives. It is at this point that library background / information service begins. After the librarian makes an effective effort to find out the background of the patron and the situation of his information needs, he then executes the search on behalf of the patron. The pertinence of the information and materials found is also evaluated and judged within this recognition of the two people involved. It means the selection of precisely that quantity and quality of information which will help the customer fill his real information need. In order words, it means screening out misinformation and inadequate information. Without doubt, the most important step that will greatly influence success or failure of the whole information service process is interpersonal communication between the librarian and patron to negotiate and find out the real information requirement. There is some distance between the inquiry: that is, the patron's expressed need and his real need, because in this endeavor one person tries to describe for another person not something he knows well but rather something he does not know. Librarians, therefore, can recall numerous experiences when the user's inquiry is vague and hard to understand. It can be said that the degree of accordance between inquiry and real information need depends upon the inquirer's understanding of his need and the ability to express this meaningfully to the librarian. Consequently, an inquiry is usually looked upon not as an absolute set request or command that can not be changed or revised, but it is rather considered as a description of area of doubt in which the question is open-ended, negotiable, and allows mutual exploration and eventual agreement that satisfies both the librarian and customer. The first objective of interpersonal communication between reference librarian and customer is, of course, in identification and clarification of real information requirement through negotiation. The following steps-translation of this need into system language, plan and design of search strategy, actual search, and delivery of information found--- will be affected by the operation of this communication process. The second, and in a sense more significant, meaning of communication lies in the establishment of a continuing, harmonious, and confident human relationship. Even if he the answer is not found or unsatisfactory, the contented user is likely to leave the library and come back to the librarian for consultation with the thought that his request has been communicated and seriously considered. I this circumstance the effort the library to be used at maximum capacity is justified and accomplished. This paper examines the general pattern of interpersonal communication during the library information service process in terms of these two major objectives. An attempt is made to outline and structure the boundaries for effective communication. Some of the problems and barriers that hinder the interface are analyzed, with suggestions that reference/information librarians should learn, keep in mind, and practice.
