This study attempts to verify the hypothesis that the interdisciplinary communication patterns may be different according to each disciplines. To put it concretely, it is intended to analyze and compare the subject distribution, the format, the age, the origin and the language of the documents of other disciplines cited in the journal articles according to each disciplines. To test the hypothesis philosophy, sociology and physics as the sample for the three disciplines, that is, humanities, social sciences, and natural sciences are sellected, and the documents cited in the journal articles published in 1966, 1971. 1976, 1981 and 1986 by the Korean Philosophical Association, the Korean Sociological Association and the Korean Physical Society are collected. And then the subject distribution, the format, the age, the origin, the language, and their use rate of the documents of other disciplines cited in the journal articles are investigated, analyzed and compared according to each disciplines. Some findings and conclusions made in the study are as follows. 1. The subject distribution of documents of other disciplines cited and its distribution ratio are different according to each disciplines, that is, humanities high, natural sciences low and social sciences medium. 2. The format and the use rate of documents of other disciplines cited are different according to each disciplines. In the three disciplines book and journal are more used than any format of documents in interdisciplinary communication while in case of the humanities and social sciences book is more used than journal, and in case of the natural sciences journal is more used than book in that communication. 3. The age and the use rate of the cited documents of other disciplines are different according to each disciplines. In case of the social sciences and natural sciences the documents of its last 20 years of publication are cited concentrately, and in case of the humanities the literature age is unconcerned. 4. The origin and the language of the cited documents of other disciplines, and its use rate are different according to each disciplines. In the humanities and natural sciences the documents published in foreign country are cited concentrately, and in the social sciences the home publication documents are more cited than the foreign. The documents of other disciplines in English language are most cited among the documents in any foreign languages in interdisciplinary communication. Putting the three disciplines in order of the use rate of the documents in English language, the natural sciences is high, the humanities medium, and the social sciences low. In the social sciences the use rate of the documents of other disciplines in Korean language is high while in the humanities and natural sciences slight.

Objectives : This report describes the original references of 154 formulas related to the use of Rhei Rhizoma main blended from Dongeuibogam. Methods : This study analyzes the original references of 154 formulas including Rhei Rhizoma as a key component in Dongeuibogam. Results : There were five types as follows: 1.There is no exact match between 154 formulas in Dongeuibogam and the original formulas in references. 2. Case that could not found the original formula in reference: 22%. 3. Case that the citation is the similar to the original reference: 4%. 4. Case that the citation is not same to expression but contents basically: 73%. 5. Case of addition of content: 1% Conclusions : Most formulas related to the use of Rhei Rhizoma main blended from Dongeuibogam are similar to the contents in the original references. But we can find that Heo Jun, who writes Dongeuibogam, modifies the contents for his intention of editing, idea and situation in Korea.

The major concern of component users who develop applications using the existing components is to confirm whether a component is collaborating with the different components in accordance with the requirements. Therefore, interoperability testing whose role is to check whether components collaborate with each other within the new operating environment not within the component development content of each component is considered as an importance research topic. In this paper, we propose a test case generation technique for interoperability test of component based software. The proposed technique defines a test model for generating test cases. The proposed technique generates test models from the use case specification and thereafter from these models, test cases for Interoperability testing are derived. In addition, we describe a tool which Implements the procedures for generating test sequences from test models.

Heating and air conditioning system is changing rapidly from the traditional HVAC central supply system to the individual supply system with electrical heat pump system (EHP) in Korean school buildings. The individual supply system has advantages to turn on and off individually and to adjust the thermal comfort separately, but energy is wasted in the unoccupied classroom when the last leaving occupant does not turn off the controller. If the controller is to be off automatically while the classroom is not in use, energy consumption would decrease dramatically. This project aims to cease the unnecessary EHP supply in vacant classroom by inputting the class schedule from the central control room to reduce the energy-spending. Experimental measurements were carried out between the controlled classroom that is turned off when not in use and the uncontrolled room that is turned on continually. Occupant's comfort and energy consumption were measured and compared between the controlled case and the uncontrolled case. The energy consumption of controlled classroom case is 30-60% less than that of the uncontrolled classroom case. This result shows that controlling the cooling supply for the unoccupied classroom using the class schedule can decrease the energy consumption remarkably. This supply control system can be used to conserve energy in school structures like universities.

Korea has shown a tremendous leap in economic development in a short span of time, and the world is watching Korea's economy with keen interest. Development of industries that are implementing information systems (IS) has played a role in leading economic growth in Korea. Because of the success of Korean firms, the creation of case studies for implementing IS in Korean firms was attempted. Despite the many case studies, analysis of the motivations and results, for implementing IS as a firm's strategic purpose, was rarely conducted. Therefore, this paper investigates some Korean firms' cases studies in order to show the best practice example of implementing and adopting IS strategically. Nine cases of Korean firms' strategic use of IS were analyzed in various industry fields. Each case consists of the following four categories: company overview, background implementing IS, adoption of IS for strategic purpose, and the results of implementing IS. In order to help various companies to take an action with their IS implementation and its strategic use, implications from the cases are summarized to show how Korean firms strategically introduced IS for solving particular problems that they had faced.

Traditionally, most cases of nicotine poisoning have been due to ingestion of nicotine pesticides. However, the increasing use of electronic cigarettes (e-cigarettes) has resulted in both intentional and unintentional exposure to concentrated liquid nicotine or "e-liquid" leading to an increase in nicotine poisoning cases. However, fatalities following the ingestion of the e-liquid are extremely rare. We report a rare case of cardiac arrest and severe encephalopathy following the intentional ingestion of e-liquid. We present the case of a 20-year-old woman who intentionally ingested liquid nicotine intended for e-cigarette use. She was found in asystole and experienced a return of spontaneous circulation (ROSC) after undergoing approximately 46 mins of cardiopulmonary resuscitation. Her plasma nicotine levels were >500 ng/ml. Despite aggressive supportive care, she was found to have encephalopathy consistent with severe anoxic brain injury on magnetic resonance imaging. In recent times, there have been some reports of deaths following liquid nicotine ingestion. Our case illustrates the potential for fatal nicotine toxicity from ingestion of e-cigarettes.

This study is conducted to estimate the air temperature decreasing effects by restoring urban streams using WRF/CALMET coupled system. The types of land use on covered streams are constructed with the land cover map from Korea ministry of environment. Restoring covered streams changes the types of land use on covered areas to water. Two different types of land use(CASE 1 and CASE 2) are inputted to the WRF/CALMET coupled system in order to calculate the temperature difference. The results of the WRF/CALMET coupled system are similar to the observed values at automatic weather stations(AWS) in Busan area. Restoring covered streams causes temperature to be decreased by about $0.34{\sim}2^{\circ}C$ according to the locations of streams and the regions that temperature is reduced are widely distributed over the restored area. Reduction of temperature is increased rapidly from morning and maximus at 13LST. Natural restoration of streams will reduce the built-up area within urban. With this, temperature reductions which are the cause to weaken the urban heat island appear. Relief of urban heat island will help to improve the air quality such as accumulation of air pollutants in within urban area.

This study investigated the perception of pre - service teachers in order to find out how paper textbooks are used in high school classes and what improvement is needed. Firstly, the results of analyzing the perception about the utilization of textbooks are as follows. First, in the case of Korean language, social studies, mathematics, science, and English, textbooks were used most frequently, and most of the respondents did not use textbooks for arts and physical education subjects. Secondly, Korean language, social studies, mathematics, science, and English textbooks are most frequently used as teaching materials. Third, in the case of Korean, social, mathematics, science, and English subjects, in addition to textbooks, problem collections were used most frequently and arts and physical education subjects showed the most use of prints. Next, the results of analyzing the perception of the improvement method of the textbooks are as follows. First, in the high school class, the response rate was high in that Korean, social, mathematics, science, and English classes needed a textbook. Most of the respondents answered that they were not necessary for the textbooks of arts and physical education subjects. Second, in order to improve the textbooks, the most demanding textbooks focused on the core basic contents, followed by self - directed learning activities, competency centered contents selection, cooperative learning activities, and teacher self - development. The demand for digital textbooks was low.
