  • The climatic impacts have been the environmental constraints with soil characteristics to achieve self sufficiency of food production in Korea. In this paper, the distribution and appearance of impacts and the changes in climatological status due to recent trend of early transplanting of rice are widely discussed to derive some countermeasures against the impacts, being focussed on cultural A long term analysis of the climatic impact appearances of the last 74 years showed that drought, strong wind, flood, cold spell and frost were the major impacts. Before 1970's, the drought damage was the greatest among the climatic impacts; however, the expansion and improvement of irrigation and drainage system markedly decreased the damage of drought and heavy rain. The appearance of cold damage became more frequent than before due to introduction of early transplanting for more thermophilic new varieties. Tongillines which were from Indica and Japonica crosses throw more attention to cold damage for high yields to secure high temperature in heading and ripening stages and lead weakness to cold and drought damage in early growth stage after transplanting. The plants became subject to heavy rain in ripening stage also. For the countermeasures against cold damage, the rational distribution of adequate varieties according to the regional climatic conditions and planting schedule should be imposed on the cultivation. A detoured water way to increase water temperature might be suggestable in the early growth stage. Heavy application of phosphate to boost rooting and tillering also would be a nutritional control method. In the heading and ripening stages, foliar application of phosphate and additional fertilization of silicate might be considerable way of nutritional control. Since the amount of solar radiation and air temperature in dry years were high, healthy plants for high yield could be obtained; therefere, the expansion of irrigation system and development of subsurface water should be performed as one of the national development projects. To minimize the damage of strong wind and rainfall, the rational distribution of varieties with different growing periods in the area where the damage occurred habitualy should be considered with installation of wind breaks. Not only vertical windbreaks but also a horizontal wind break using a net might be a possible way to decrease the white heads in rice field by dry wind. Finally, to establish the integrated countermeasures against the climatic impacts, the detailed interpretation on the regional climatic conditions should be conducted to understand distribution and frequency of the impacts. The expansion of observation net work for agricultural meteorology and development of analysis techniques for meteorological data must be conducted in future together with the development of the new cultural techniques.

  • The purpose of this research is to compare and analyze the brassiere patterns sold in Shanghai and Korea and to present basic materials needed in developing the brassiere patterns in Chinese adult women market. The study subject which is to find the difference in brassiere patterns of Korea and China has been selected of 3 Korean brands and 4 Chinese brands. 1. For the brassiere patterns sold in Korea, it were using the same size for the width of Hook&Eye, space between the shoulder lace on the back, slope of wing and the location of the Keeper was similar. 2. For the cup supporting base, Chinese brassiere covers the lower part of the breast and as it is not comfortable and has a phenomenon of loosening up, there were severe puckering. For issues in the wearing experiment, amendments in patterns with the cup part was required. 3. Chinese brassieres were big differences in wing angles and for Aimer, it had the steepest trend in wings and thus the wings headed down and for Gujin, as the angle of the wing was smaller than $90^{\circ}$, it was heading upward. 4. Upon comparing the patterns of the Korean and Chinese brassiere, although most of the sizes excluding the wing angle had similar sizes, there was big differences in the wing angle. The reason why the brassiere patterns sold in China had bigger wing angle was due to the fact that more Chinese women had sway back body type than the Korean women and should reflect such difference in body size into making the brassiere patterns for each women.

  • This study is to survey the present book numbers used in Korean libraries. to analyze their problems. and to suggest improvement in the book numbers. As the results of the survey several suggestions are derived as follows. 1. The education to the librarians about the kinds and the application methods of the book numbers used in Korean libraries should be sufficiently offered. 2. The present book numbers used should be expanded in detail for avoiding the duplication of the call numbers. Also when book numbers are assigned. shelf list cards should be examined one by one not to give the same number. If the book numbers are overlapped in the state not to expand further. libraries should establish a detailed expansion rules according to their respective situation and maintain it consistently. However, it is impossible for libraries operating open stack systems to arrange books on the shelves in call number sequence, therefore libraries can solve the problems as they accept duplication cases. 3. Since the object word of main mark IS a heading In main entry, we must apply cataloging rules to it closely. 4. For expanding book numbers widely it is desirable that the subsidiary mark of the book numbers which is the most prevalent in general and will be the most preferable In the future through the survey should be added and be provided. 5. The book numbers used being changed, we are to assign new book number leaving former materials as they are at the point of adopting a new book number. So aged materials are stored in a repository or on a compact shelf in the stack, will be discarded or weeded according to subjects after a certain period of time. 6. With library automation bringing together all the books of an author in a particular subject or in a particular form and avoiding completely duplication in open stack systems are meaningless. Rather than chronological book numbers, distinguishing clearly new materials from aged materials and controlling the stack spaces mechanically and effectively, can be regarded as the most modern and future-oriented of all the book numbers.

  • The conning display which is located in the ship bridge shows the various important information such as ship position, ship speed, track data, rate of turn, thruster rpm so on, and is one of the IBSs(Integrated Bridge Systems). In this study, the survey was conducted for ten officers to find the importance and using frequency of the information which were displayed in the conning display. The results showed that the information of drift speed, ship speed, wind direction and wind force, rate of turn, sea water depth, ship position, heading, thrust rpm, alarm, rudder command and angle got high scores and it meant that these information were very important and high frequency of use during the navigation. The optimized contents arrangement in conning display was suggested based on importance and using frequency of information. The experiment using eye-tracking system was conducted to compare the performance time and error rate of nine different scenarios for suggested arrangement display and three other existing displays. The results showed that the suggested arrangement was the best in performance time and error rate. The scenario concerning the direction and speed of wind showed faster performance time and lower error rate than other scenarios. The movement of subject's eye tended to search from the center and to avoid the comer, called 'the comer effect.' It is expected that the results of this study could help for the bridge staff to grasp the sailing information easily and to cope with the given situations promptly.

  • 본 연구는 우리 사회에서 벌어지고 있는 기념일을 둘러싼 갈등과 투쟁에 주목해 기념일에 관해 라캉과 알튀세르적 접근을 시도했다. 연구대상으로는 8.15, 한국전쟁, 3.1절, 임시정부를 선정했으며, 이들에 대한 기념 투쟁들의 양상과 그 변화 과정을 살펴보았다. 연구방법으로는 라캉과 알튀세르의 이론과 개념 등을 활용했다. 연구결과는 기념투쟁이 19세기말 진행된 근대화 초입을 그 기원으로 삼는 것으로 분석되었다. 즉 일제강점에 의해 강압적으로 이루어진 근대화가 우리 사회에 외상과 균열을 냈으며, 이는 이데올로기 및 환상과 접합되어 사회적 갈등의 형상을 취하게 되었다. 그것이 수렴되는 지점이 바로 기념일이다. 기념일과 기념투쟁이 과거에 대한 사회적 기억의 현상으로서 존재할 수 밖에 없는 것이라면, 이들은 분열된 과거의 회귀가 아니라 내일을 향하는, 균열을 메우는 사회를 만들고자 하는 의지를 되새기는 날이 되어야 할 것이다.

  • Objectives : This study aimed to analyze the trends in research and development projects related to herbal medicine and natural products in the field of traditional Korean medicine (TKM) over the past 20 years. Methods : Research projects were identified using "Korean medicine" as the subject heading in the National Science and Technology Information Service. The included projects investigated Korean medicine, natural products, or were related to the TKM industry. Data pre-processing and network analysis were performed using Python and Networkx package, and the network was visualized using the ForceAtlas2 visualization algorithm. Results : 1. Over the study period, 4,020 projects were conducted with a research budget of KRW 835.2 billion. Seven institutions performed over 100 projects each, accounting for 2.4% of all participating institutions, and the top 10 institutions accounted for 58.9% of total projects. 2. Obesity was the most frequently mentioned disease-related keyword. Chronic or age-related diseases such as diabetes, osteoporosis, dementia, parkinson's disease, cancer, inflammation, and asthma were also frequent research topics. Clinical research, safety, and standardization were also frequently mentioned. 3. Centrality analysis found that obesity was the only disease-related keyword identified, alongside TKM-related keywords. Standardization, safety, and clinical trials were identified as central keywords. Conclusions : The study found that research projects in TKM have focused on standardizing and ensuring the safety of herbal medicine, as well as on chronic and age-related diseases. Clinical studies aimed at verifying the effectiveness of herbal medicine were also frequent. These findings can guide future research and development in herbal medicine.

  • The library catalog is considered an important tool to provide library users with conveniences making a search for necessary information. Accordingly, the purpose of this study is to investigate "behaviors and attitudes" of library users in a university library using online and card catalogs together, to compare their distinctions between online and card catalogs and then to bring about reforms for the development of future cataloging, thereby improving the utilization of online catalog and its service expansion. For this, this paper carried out a survey research which was randomly questionaired 280 library users of four universities in Seoul from March 28th to April 16th 1996. Major findings are as follow : 1. Library users tended to use more online catalog(50.0%) than card catalog (21.9%). 2. The main reasons the library users us online catalog were time saving(24.0%), convenience of use(21.3%), multiple searching possibility (16.2%), and the preferences of card catalog were location of library materials(34.6%), time saving(17.5%), Bibliographic information(14.9%). 3. The major access points which library users utilized mostly in their online catalog are title(30.3%), author(29.2%) and subject heading (17.6%), and for card catalog, title(40.5%), author(34.6%) and call no.(11.1%). 4. The methods library users learned to use online catalog are terminal screen(44.7%), online manual(26.1%), and for card catalog, library orientation(42.6%), librarian's help(18.5%). 5. It was shown that library users were not mostly satisfied about their searching results: the users satisfied with online catalog in the order of partly(46.2%), as expected(42.3%), more than expected(10.4%), and with the card catalog in the order of partly(54.6%), as expected(27.3%), more than expected(10.4%). It was found that although library users preferred online catalog more than card catalog, 54.8% of the total catalog users were not satisfied about the search results they have had. 6. The items which library users want to add to online catalog are catalogs of materials other libraries have(41.6%), catalogs of the materials the library has(29.3%), titles of serial articles(17.7%). And the additional services library users want are checking function of loan materials and reservation of materials(15.5%), subject headings(14.5%), more terminals(13.4%), catalog use explanations(12.9%), multiple access points(11.0%), searching function of contents, abstracts, and indexes(9.6%). Considering the fact that library users tend to use more favorably online catalog than card catalog and the trend that library change from card catalog to online catalog, it is strongly recommended to su n.0, pply students with formal and informal training programs for online catalog use.talog use.
