본 연구의 목적은 국내 K 대학도서관을 대상으로 사례연구를 실시하여 대학도서관에서의 도서 선정 주체에 따른 도서 선정의 효과성을 비교 분석하는 데 있다. 이를 위하여 사례 도서관으로부터 최근 3년간의 단행본 수서 및 대출 기록을 바탕으로 7,717종(16,809권)을 조사 대상 도서로 선정하였고 이에 대한 교수, 사서, 학생 3집단의 도서 선정 및 대출 현황을 조사 분석하였다. 연구 결과사서에 의해 선정된 도서의 비율이 전체의 약 76%로서 가장 높은 비율을 차지하였으며 그 다음 학생, 교수의 순으로 도서 선정 비율이 높게 나타났다. 각 신분별로 선정된 도서를 대상으로 미대출 도서의 비율을 조사한 결과 사서에 의해 선정된 도서의 미대출 도서 비율이 가장 낮게 나타났다. 1회 이상 대출 이력이 있는 도서를 대상으로 대출비율을 조사한 결과에서는 학생에 의해 선정된 도서의 대출 비율이 가장 높게 나타났다.

The dynamical model forecasts using state-of-art general circulation models (GCMs) have some limitations to simulate the real climate system since they do not depend on the past history. One of the alternative methods to correct model errors is to use the canonical correlation analysis (CCA) correction method. CCA forecasts at the present time show better skill than dynamical model forecasts especially over the midlatitudes. Model outputs are adjusted based on the CCA modes between the model forecasts and the observations. This study builds a canonical correlation prediction model for subseasonal (June) precipitation. The predictors are circulation fields over western North Pacific from the Global Seasonal Forecasting System version 5 (GloSea5) and observed snow cover extent over Eurasia continent from Climate Data Record (CDR). The former is based on simultaneous teleconnection between the western North Pacific and the East Asia, and the latter on lagged teleconnection between the Eurasia continent and the East Asia. In addition, we suggest a technique for improving forecast skill by applying the ensemble canonical correlation (ECC) to individual canonical correlation predictions.

Purpose: Investigates the results of CPR operation in visited patients with arrest state, and element to affect the results, and it is checks a problem, and it is made to promote. Methods: As for this study, analysis studied the results that operation CPR with the object arrest patients of 69 visited Jecheon Seoul hospital emergency center for during the period from January 2002 to February 2005. It was played writing partly changed In-hospital Utstein Style, and to stick a record in it. Paramedic which participated in CPR directly did the record of a variable, As for the data processing, use SPSS Version 12.0 for Windows. Results: It was male 68.1% female 31.9% for 69 people, and the sex ratio didn't affect return of spontaneous circulation, with female 8 people to male 16 people for ROSC(Return of spontaneous circulation) 24 people. with female 14 people to male 31 people for NROSC(Non-return of spontaneous circulation) 45 people(p>0.05). The initial EKG rhythm was asystole 34.8%, VF 31.9%, The case that initial EKG was VF compared it to a patient of asystole, and a survivor had a lot of VF and there were a lot of survivors(p<0.05). The wasn't relativity between VF and PEA(p>0.05), The CPR lead time was short in ROSC with NROSC $25.0{\pm}15.0$ minutes, ROSC $11.9{\pm}10.7$ minutes(p<0.01). Epinephrine administer time was NROSC $3.0{\pm}4.1$ minutes, ROSC $2.1{\pm}1.9$ minutes(p>0.05). It was survivor 18 people(21.1%) than 24 hours and the PAM Index affected in ROSC. with $9.0{\pm}1.2$ points NROSC, with $1.6{\pm}1.7$ points ROSC(p<0.01). A correlation was high between a CPR lead time and PAM Index(p<0.02), a correlation was examined by being high between ROSC and a CPR lead time, PAM Index(p<0.01).

Objectives This study aimed to report the effectiveness of abdominal Daoyin and lymphatic circulation technique in conjunction with whole-body articulation mechanics technique therapy in treating indigestion. Methods Three patients who suffered from dyspepsia and abscess after consuming foods incompatible with their constitution, following a 10-year implementation of a constitutional diet at a local Korean Medicine clinic, visited a Korean Medicine Hospital. The patients underwent treatment with abdominal Daoyin and lymphatic circulation technique. The effects of these techniques were analyzed using a retrospective record analysis method. Results Following the implementation of abdominal Daoyin and lymphatic circulation technique for indigestion, the numeric rating scale scores improved significantly. Case 1 improved from 9 to 2, case 2 from 6 to 0, and case 3 from 5 to 1. Conclusions While acknowledging the limitations of being a case report involving only three patients and the absence of specialized outcomes for digestive issues, this report may provide a preliminary basis for considering the efficacy of Chuna manual therapy in indigestion treatment.

New realities of social relations are changing the understanding of certain phenomena, including the emergence of new concepts among the objects of property rights, such as: virtual assets, and the circulation of virtual assets. The rapid development of the virtual assets market involves the legislative consolidation of the status of such assets, changes in taxation, their circulation, and so on. These circumstances increase the interest in the study of virtual assets as the latest object of property rights and necessitate the study of this topic. The work aims to explore the theoretical developments and regulations on virtual assets in the modern world, as well as to summarize the conclusions about virtual assets as the latest object of property rights. The object of research is the content of the concept of "virtual asset" and its legal status. The methodology of work is represented by a set of methods and techniques that were used to achieve this goal, namely: hermeneutic, historical, extrapolation, comparative law, generalization, analysis, synthesis, and deduction. The study analyzed different approaches to understanding virtual assets, analyzed the characteristics of virtual assets, and concluded that in today's conditions there is no single unified legal regulation of virtual assets, although many countries are moving towards consolidating the status of virtual assets.

During summer (JJA) of 2004, a record-high temperature in Korea appeared at Miryang ($38.5^{\circ}C$ on July 30). Moreover, Miryang showed the most frequent occurrence (25 days in JJA) of the daily highest temperature among observational sites in Korea. Based on meteorological analysis, it is found that this phenomenon is caused by neither the global warming effect nor the urban climate effect. It is caused by the mesoscale and synoptic and/or global scale atmospheric circulations, as evidenced by several factors described below. Firstly, the hottest areas have normally occurred not at a point but over an area, particularly along an axis connecting Sancheong and Daegu. But in 2004, this axis has moved southward and locates over Namhae-Miryang due to northerlies that were induced by the heating effect related to the low snow-cover on the Tibet Plateau. Secondly, although the maximum temperature was the highest among observational sites in Korea, the daily mean temperature and the number of nights with air temperature over $25^{\circ}C$ were not the highest at Miryang. Thirdly, the downdraft induced by the second circulation of typhoon and abnormal development of the North-Pacific High were found to have exerted an important role.
