From an ecological point of view, the western part of the Atlantic sector is one of the most productive areas in the Southern Ocean. Antarctic krill (Euphausia superba) and krill-dependent predators such as fish, seals, and birds are abundant there, and most krill fisheries have operated in this area since 1970s. The hottest issues for the proper management of krill resources nowadays are to determine total biomass in this area, and to identify environmental forces controlling stock fluctuation. This paper reviews and collates information on ongoing oceanographic activities in the Antarctic Peninsula region concerning these issues. To delineate the status and function of Antarctic krill population in Antarctic marine ecosystems, multinational researches along the Antarctic Peninsula area have been developing recently. Four member states of CCAMLR (Japan, Russia, UK, and USA) had conducted acoustic surveys in January-February 2000 (socalled CCAMLR-2000 survey), and krill standing stock at 120 kHz was estimated to be 44.29 million metric tonnes in the western Atlantic sector of the Southern Ocean. On the other hand, the Southern Ocean GLOBEC (SO-GLOBEC) Programme has prepared a serial winter survey to examine the factors that govern krill survivorship and distribution in relation to shelf circulation processes. Ship-based surveys using ice-breakers are being conducted by three nations (Germany, UK, and USA) around the Marguerite Bay during the austral fall and winter 2001 and 2002. In addition to these two large-scale surveys, some CCAMLR members have carried out joint oceanographic surveys near the South Shetland Islands to detect ecosystem changes since 1994. Especially from December 1999 to February 2000, in conjunction with CCAMLR-2000 survey, four nations (Japan, Korea, Peru, and USA) conducted acoustic surveys to produce time-series information on krill distribution and biomass near the South Shetland areas. Though the aims of each program and the approach to solve the scientific questions were different each other, the results from each program fill the gaps between programs. Further cooperation and exchange in these activities could be beneficial to each program.

To cope with recently increasing demand for data traffics, heterogeneous networks have been actively studied, where small cells are deployed within a macro cell coverage with the same frequency band. To mitigate the interference from the macro cell to small cells, an enhanced Inter-cell Interference Coordination (eICIC) technique has been proposed, where ABS (Almost Blank Subframe) is used in time domain. However, there is a waste of resource since no data is transmitted in a macro-cell in ABS. In this paper, we propose a new interference management method by using a 3D sector beam based on Active Antenna System (AAS), where Genetic Algorithm (GA) is applied to reduce the antenna gain toward a small-cell. With the proposed scheme, the macro-cell and small cells can transmit data at the same time with the AAS antenna pattern generating reduced interference to small cells. The performance of the proposed scheme is evaluated by using an LTE-Advanced system level simulator.

Objectives : Though Tsutsugamushi disease has been reported with increasing frequencies in rural communities in Korea, it is not easy to find the nursing investigations. Methods : We have conducted a survey on 30 cases who had the fever as a chief complaint, then clinically ruled out the Tsutsugamushi disease in autumn of $2000{\sim}2001$. Data were collected retrospectively by investigation of the general characteristics, clinical and laboratory findings, their nursing care. Findings: Of 30 cases, 46.7% were farmers, and 60.0% had chances of exposure to fields or mountains. The characteristic symptoms and signs were febrile sense and chill(100.0%), headache(80.0%), and eschar(66.7%). Abnormal laboratory findings were anemia (23.3%), elevated AST(60.6%), ALT(63.3%), and abnormal urinalysis findings(50.0%). 53.3% were serologically confirmed as Tsutsugamushi disease. Therapeutic nursing cares were composed with warm up by blancket(50.0%), Ice bag(50.0%) and doxycycline antibiotic therapy(100.0%). Other nursing care for them included fluid therapy(100.0%) and nutritional support with regular(56.7%) or soft diet(43.3%). Conclusion: The above results indicate nurses who take care of acute febrile clients should make her responsible for the fever and pain management as well as give education for infection control for the community inhabitants.

Purpose: A survey was done on knowledge of pain and pain interventions by clinical nurses in Deagu city and Kyoungbuk province. Method: The participants in this study were 209 nurses who worked in Daegu city, and 190 nurses who worked in Kyoungbuk province. The data were collected from August 5, to September 15, 2002. The data were analyzed with SPSS WIN 10.0 program using numbers, percentages, averages and standard deviation with t-test and ANOVA. Result: Out of a total of 30 points on general knowledge of pain, the clinical nurses had a high score of 28, and a low of 10. The average was 18.6 (SD=3.14). Of the participants, 57.9% reported not having had any pain education and 67.9% agreed that education is a necessity. Of pharmacological interventions, Tylenol had the highest score at 3.44 out of a possible 4 points. The most frequent route for giving medication was intramuscular injection (42.6%) and for 62.7%, there was a decision by the physician for routine medication or prn. On reactions after medication, moderate relief had the highest frequency (41.9%), and for side effects after the medication, feeling of nausea was most frequent (70.4%). Of the nonpharmacological approaches to pain relief, ice bag had the highest score with 2.95 out of a possible 4. Judgement to give medication was made by the nurse for 50.1% of the participants and 647% reported a little relief from pain. Conclusion: Based upon the results, continuing education and developing a better education programs (including pain mechanism, pain assessment, pharmacological interventions and nonpharmacological interventions) are needed for systematic pain management. Nurses need a high level of knowledge of pain, to be active in pharmacological interventions and nonpharmacological interventions.

This study is conducted to compare the problems affecting dietary habits and health status between a long-term exercise group and non-exercise group of males older than 50 years. Most subjects of the two groups consider regular exercise to be the most important factor for maintaining health, and recognize hypertension as the number one concern. The most common nutritional supplement among subjects is multiple vitamins, and sleeping time range from 6~8 hours. Breakfast fasting rate was 15.9% among non-exercise group (NEG), where overeating and eating out rates were higher among exercise group (EG) when comparing to NEG. Fasting rates of breakfast, and consumption rates of milk and dairy products, vegetables such as kimchi, and fruits and fruit juices are higher among the EG. Overeating and eating out rates are lower among NEG, whereas eating rates of proteins like meat, fish, eggs, beans, fried foods, high-fat meats carbonated drinks, ice cream, and salt intakes are higher. Rates of health, dietary habits, and nutrient intakes are higher among EG. Energy intakes among the two groups were below the standard level, Vitamin $B_2$ intake is low in EG, and folic acid and calcium intakes were higher in NEG. The exercising group care more about health, eating habits and nutrient intakes, and low smoking rates are being observed. Thus, specific dietary improvement programs for adult men, are required, and it is necessary to consider the practice of nutrition education.

Weather is one of the main causes of aircraft accidents, and among the phenomena caused by weather, icing is a phenomenon in which an ice layer is formed when an object exposed to an atmosphere below a freezing temperature collides with supercooled water droplets. If this phenomenon occurs in the rotor blades, it causes defects such as severe vibration in the airframe and eventually leads to loss of control and an accident. Therefore, it is necessary to foresee the icing situation so that it can ascend and descend at an altitude without a freezing point. In this study, vibration data in normal and faulty conditions was acquired, data features were extracted, and vibration was predicted through deep learning-based algorithms such as CNN, LSTM, CNN-LSTM, Transformer, and TCN, and performance was compared to evaluate blade icing. A method for minimizing operating loss is suggested.

This research interprets the unique hybridity of the pavilion architecture in the Joseon Dynasty, in which the name and form do not match and the rooms and floors are combined in various ways, through the Confucian architectural prototype Muijeongsa(武夷精舍) built by Zhu Xi(朱熹). The architectural representation of Muijeongsa, developed against the background of the mid-Joseon period of active pavilion management by Sarim(士林) groups, the spread of ondols due to the Little Ice Age, and an architectural culture following the footsteps of the Zhu Xi is likely to have influenced the perception and practice of pavilion architecture. In this research, by examining and analyzing the contents of the Muijeongsa Japyeongbyeongseo(武夷精舍雜詠幷序) containing the architectural composition of Muijeongsa, it was confirmed that different types of spaces such as Dang(堂), Jeong(亭), Jae(齋), and Gwan(館) are integrated into Muijeongsa. Based on this, the main examples of the architecture of Jeongsa in the mid-Joseon Dynasty were reinterpreted into four types from the perspective of the combination of Dang and Jeong, and the junction of Jeong and Jeongsa. Dang and Jeong were either juxtaposed as separate buildings or implemented with a relationship of inclusion within one building. And the concept of Jeong, which was considered secondary to Dang, was used as a category that was replaced with the Jeongsa itself. Lastly, the name 'Jeongsa' was used, but the location had a strong character of 'Jeong', and the architectural form adhered to the form of 'Dang', thereby exquisitely reconstructing the composition of Muijeongsa as a single building.

The initiation and growth processes of cyclic ice body in porous systems are affected by the thermo-physical and mass transport properties, as well as gradients of temperature and chemical potentials. Furthermore, the diffusivity of deicing chemicals shows significantly higher value under cyclic freeze-thaw conditions. Consequently, the disintegration of concrete structures is aggravated at marine environments, higher altitudes, and northern areas. However, the properties of cyclic freeze-thaw with crack growth and the deterioration by the accumulated damages are hard to identify in tests. In order to predict the accumulated damages by cyclic freeze-thaw, a regression analysis by the response surface method (RSM) is used. The important parameters for cyclic freeze-thawdeterioration of concrete structures, such as water to cement ratio, entrained air pores, and the number of cycles of freezing and thawing, are used to compose the limit state function. The regression equation fitted to the important deterioration criteria, such as accumulated plastic deformation, relative dynamic modulus, or equivalent plastic deformations, were used as the probabilistic evaluations of performance for the degraded structural resistance. The predicted results of relative dynamic modulus and residual strains after 300 cycles of freeze-thaw show very good agreements with the experimental results. The RSM result can be used to predict the probability of occurrence for designer specified critical values. Therefore, it is possible to evaluate the life cycle management of concrete structures considering the accumulated damages due to the cyclic freeze-thaw using the proposed prediction method.
