For decades, general services and accounting officers have been dominant forces in collection development activities in college and university libraries in Korea. The role of certified librarians has been rather peripheral. This has been allowed by the fact that library acquisitions departments had to be headed by non-librarian general administrative officers by the government regulation. The philosophy behind this regulation was that acquiring library materials was not any different from simple purchasing act of other useful goods in the marketplace. In affiliation with the element of general administrative officers, domestic book-sellers also had a great influence in collection building activities in college and university libraries in Korea. This has been made possible by the fact that no other people could su n.0, pply library materials, especially foreign library materials. It has been pointed out for years that the mechanism in which general administrative officers and domestic book-sellers had a greater say in library acquisitions activities was especially inefficient in acquiring wanted materials in wanted speed and in wanted price. In this mechanism, books and periodicals were mere goods. They were not perceived as intellectual property holding information and knowledge in them. Since the student movement to revolutionize the library system of the Pusan National University, September 1987 to December 1988, the creative and progressive elements in this university library have been making great efforts to change the acquisitions system in this library into a more efficient one by putting certified librarians at the center of the whole acquisitions process. These efforts have been successful to a certain degree. In this discursive study of the case of the Pusan National University Library, I have tried to achieve a social description of the library process in which progressively motivated librarians succeeded in alienating administrative officers and book-sellers and in grasping in their hands the hegemony in the collection building aspect of library activities. It has been discovered that this was possible only when the librarians were mature enough to have their kind of professionalism, i.e., professional ethics and craftsmanship.

Zhang Yuan-Su(張元素) was a doctor of the Jin(金) period, who was followed by Li Dong-Yuan(李東垣) and Wang Hao-Gu(王好古), creating the Yishui School(易水學派). The most notable aspect of his theory is the internal organs(臟腑)-based diagnostic system. He organized previous methods based on the internal organs and applied the same methodology in treatment as well. The Zangfu-biaoben-xushi-hanre-yongyaoshi(臟腑標本虛實寒熱用藥式) is one of his major publications in which diagnostic and treatment methods are organized in a simple manner. In this book, the diseases of the organs are divided into the tip and root(標本). This paper investigates the standards of categorizing tip and root diseases through analysis of all symptoms of both tip and root diseases of the five internal organs. Then the results of the analysis were used in grasping the similarities and tendencies of the root disease and tip disease. Conclusively, root diseases indicate disorder in the internal organs themselves. Tip diseases indicate disorder in the channels and collaterals, diseases caused by exterior pathogens or symptoms that manifest in the exteriors of the body. Such categorization is thought to have been established to eliminate diagnostic error that could occur from using the same expressive means in describing symptoms with different causes, in the process of forming an uncomplicated diagnostic system.

Recently, the rapid economic growth has caused urban problems due to the increase of urban population and the rapid expansion as a result of exodus phenomenon in rural territories. In order to solve the problems, we need to perform rational and effective plans for national land development. Generally, we need speedy and accurate topographical information of the object area to go ahead with balanced national land development. Acquisition method for topographical data include utilization of existing geographic information such as national base maps and related thematic maps and grasping of accurate present condition of object area using aerial photographies or satellite images. When the object area is small, existing methods for acquiring topographical information reveals imitations in accuracy, speed and economic aspect. Therefore, development of a new method is in order. As a result of this study, we recogized that Photo Balloon System to be manufactured and digital ortho-map to be generated could be used to obtain a topographical information for small areas.

As online shopping is activated by the development of the Internet, consumers' purchase form is changing from the traditional face-to-face purchase method to online purchase method. Many sellers have flowed into shopping malls, and competition among sellers is very intense. Therefore, sellers in shopping malls need to establish rational marketing strategies by analyzing consumer purchase patterns and product sales trends. In this paper, we analyzed the purchase price of consumers by analyzing the product price, rating, and sales quantity of competitors who sell the same product in open shopping malls by time zone. In addition, the collected information was visualized in a chart so that the company's and competitors' sales trends could be easily compared. Using the above system, it is possible to predict the sales volume through the analyzed purchasing pattern and to select the reasonable price of the product by grasping the sales trend.

Objective: The purpose of this study was to develop and evaluate smart secondary controls using iPad for the drivers with physical disabilities in the driving simulator. Background: The physically disabled drivers face problems in the operation of secondary control devices that accept a control input from a driver for the purpose of operating the subsystems of a motor vehicle. Many of conventional secondary controls consist of small knobs or switches that physically disabled drivers have difficulties in grasping, pulling or twisting. Therefore, their use while driving might increase distraction and workload because of longer operation time. Method: We examined the operation time of conventional and smart secondary controls, such as hazard warning, turn signal, window, windshield wiper, headlights, automatic transmission and horn. The hardware of smart secondary control system was composed of iPad, wireless router, digital input/output module and relay switch. We used the STISim Drive3 software for driving test, customized Labview and Xcode programs for interface control of smart secondary system. Nine subjects were involved in the study for measuring operation time of secondary controls. Results: When the driver was in the stationary condition, the average operation time of smart secondary devices decreased 32.5% in the normal subjects (p <0.01), 47.4% in the subjects with left hemiplegic disabilities (p <0.01) and 38.8% in the subjects with right hemiplegic disabilities (p <0.01) compared with conventional secondary devices. When the driver was driving for the test in the simulator, the average operation time of smart secondary devices decreased 36.1% in the normal subjects (p <0.01), 41.7% in the subjects with left hemiplegic disabilities (p <0.01) and 34.1% in the subjects with right hemiplegic disabilities (p <0.01) compared with conventional secondary devices. Conclusion: The smart secondary devices using iPad for people with hemiplegic disabilities showed significant reduction of operation time compared with conventional secondary controls. Application: This study can be used to design secondary controls for adaptive vehicles and to improve the quality of life of the people with disabilities.

Objective : We did a comparative study about characteristics of oriental medical books. As a result, we took notice of classification in the nominal terms by semantic type of UMLS(Unified Medical Language System). By using classified nominal terms, comparative study can be more effectively. So, we selected another oriental medical book and classified nominal terms in it by semantic type of UMLS. By result of classification, we have attempted to study about comparison between oriental medical books and development of medical theories. Method :We have made a comparative study on classification in the nominal terms between "Biwiron(脾胃論)" and "Soayakjeungjikgyeol(小兒藥證直訣)" according to the below the procedure. (1) Making a nominal terms list of "Soayakjeungjikgyeol(小兒藥證直訣)" and grasping contextual meaning of nominal terms of it. (2) Modification and supplementation about semantic type of UMLS for "Soayakjeungjikgyeol(小兒藥證直訣)". Using the modified classification system, we classified nominal terms. After this process, we arranged classified nominal terms by Haansoft Hangul 2007. (3) Comparing classified nominal terms between "Biwiron(脾胃論)" and "Soayakjeungjikgyeol(小兒藥證直訣)". Result : In the "Soayakjeungjikgyeol(小兒藥證直訣)", there are more than 2,519's nominal terms and different categories of semantic type of UMLS classification from "Biwiron(脾胃論)". Through comparison between their classification of nominal terms, we can understand the characteristics of the two and their development of medical theories.

This study was carried out to develop a newly designed ovum pick-up(OPU) instrument for ultrasound-guided transvaginal follicular aspiration in cows. This new instrument consists of out- & inner-layer stainless pipes and a grip with a trigger(hand) switch. Some gauge types of disposable needles and tubes can be attached to this inner pipe. With this instrument, while grasping an ovary with one hand, the other hand can handle in apiration and vacuum on/off with the least assitant's help. With this instrument the mean recovery rate of bovine follicular oocytes was 45.2%. In recovered oocytes, usable oocytes(Grade I & II) were 30.4% and this rate meant 1.4 oocytes per ovary. For 30 days after initial aspiration with this instrument, some adverse effects such as adhesion, hemorrhage, hematoma and other mass formation in/with ovaries were also examined by rectal examination, ultrasonographic and endoscopic images. Adhesion was found in one ovary 1 week after aspiration, and hemorrhagic lesion was found 1-2 days and petechia were found 3-5 days after aspiration and there was no remarkable adverse effects. It was found that this instrument could be applicable and safe for ovum pick-up in cows.

Recentrly, early dental care for children is becoming more important, and the number of children patients' dental services is on the rise. So, a variety of seduction therapies are needed to alleviate the tension in children who are anxious about dental care. This paper describes the development process and contents of system that can display the animation of different stories according to the treatment stage by grasping the use state of the treatment device in real time. In the animation, the hreo character and the villain, the cavity character, appear and the hero defeat the villain at each treatment stage. Animation is played when treatment starts and ends after treatment. Current existing one-side played animation of dental clinics is not enough to attract children's attention. If the flow of animation changes depending on the treatment process, it will give children a different enjoyment and consequently ease the tension over the treatment.

To understand the impact of 2015 spring drought on crop production of DPRK (Democratic People's Republic of Korea), we analyzed satellite and weather data to produce 2015 spring outlook of rice paddy field and rice growth in relation to weather anomaly. We defined anomaly of 2015 for weather and NDVI in comparison to past 5 year-average data. Weather anomaly layers for rainfall and mean temperature were calculated based on 27 weather station data. Rainfall in late April, early May, and late May in 2015 was much lower than those in average years. NDVI values as an indicator of rice growth in early June of 2015 was much lower than in 2014 and the average years. RapidEye and Radarsat-2 images were used to monitor status of rice paddy irrigation and transplanting. Due to rainfall shortage from late April to May, rice paddy irrigation was not favorable and rice planting was not progressed in large portion of paddy fields until early June near Pyongyang. Satellite images taken in late June showed rice paddy fields which were not irrigated until early June were flooded, assuming that rice was transplanted after rainfall in June. Weather and NDVI anomaly data in regular basis and timely acquired satellite data can be useful for grasping the crop and land status of DPRK, which is in high demand.
