To investigate the anti-proliferative effects of an aqueous extract of Cordyceps militaris (AECM) on the growth of human lung carcinoma cell line A549, we performed various biochemical experiments such as the effects of AECM on the cell proliferation and viability, the morphological changes, the effects on expression of apoptosis and cell growth-regulatory gene products. Results obtained are as follow; AECM treatment declined the cell viability and proliferation of A549 cells in a concentration-dependent manner. The anti-proliferative effect by AECM treatment in A549 cells was associated with morphological changes such as membrane shrinking and cell rounding up. Taken together, these findings suggest that AECM-induced inhibition of human lung cancer cell proliferation is associated with the induction of apoptotic cell death via regulation of several major growth regulatory gene products, and C. militaris may have therapeutic potential in human lung cancer.

Nowadays, fashion is high evaluated as a mean of self expression as well as a formative art itself, The moderns' elevated beauty sense and strong desire for individuality expression have not only advanced various and refined fashion presentation but also led to expansion of fashion to a total coordination covering hair and makeup. Of them, hair styling does play an important role in rounding out the various image of fashion. It is not only far from omittable part but also, out of simplicity in the past, taking formative characteristics in form and structure day by day. Especially, artistic elements of modern arts are being introduced as motives, and of which representative is e introduction of kinetic art which is thought the artistic approval on mechanization trend in the 20th century. Thus, the study was intended to investigate how and in what forms the various features of kinetic arts is reflected in the modern hair shaping, and to suggest a new prospect of kinetic art-applied hair shaping.

Subcortical Aphasia is not among the typical eight types of aphasia. It is characterized as cerebral infarction or hemorrhage occurring in the region of the left basal ganglia internal capsule, accompanied with ventrical rounding and white matter. Subcortical aphasia is similar to transcortical aphasia in its symptom of repetition, and classification is difficult. Language ability can change rapidly over several months so a patient's convalescence is unpredictable. Because of the peculiarities of subcortical aphasia there are many conflicting hypotheses. Various clinical approaches and medical treatments for speech disorder(aphasia) have been presented. In Korean medicine, there are many studies about speech disorder, but few reports are related to subcortical aphasia. An aphasic stroke patient who was treated with acupuncture, herbal medicine(Jihwangumja), and speech-language therapy is here reported. Significant improvement in language abilities was seen over three months. Further clinical study of subcortical aphasia is needed.

This paper aims to research the influence of mother tongue (Polish) on the perception of a foreign language (Korean) i.e. how vowel sounds that are totally unfamiliar to the listeners are perceived, how the similar sounds are perceived and whether the perception differs according to the phonetic values of the neighbouring sounds. As a result, the degree of the influence of Ll on the vowels of L2 is different in each case and mostly depends on the familiarity of the vowel in question and on the articulatory similarities between the vowels in both languages. The results are as follows; The best perception was observed with Korean /i/ and /a/ (very similar places of articulation in both languages). The worst degree of perception was Korean /(equation omitted)/ that is very unfamiliar to Polish subjects. Vowels that are not so different from the Ll sounds were perceived fairly well. Another important result is that Polish listeners seem to be more sensitive to lip rounding than to the height of the tongue. The role of the neighbouring sounds seems to be of a considerable importance, Depending on the preceding vowel, a sudden drop or rise in the degree of the perception was observed.

Region-of-Interest is the region within the image selected for the users needs. The development of multimedia has made the expectation of image telecommunication higher, but the usage of the image, image transmission time, and image storage create problems. When transmitter or the receiver stops transmission at some point, we can still see the general image and the ROI maintains better image quality if the ROI is specified beforehand. In this paper, three methods are proposed and constructed for the transmission of ROI. In the first method, the ROI and the background are separated and then encoded as described above. The second method is to encode without separating the ROI and the background. The masked region is scaled and the coefficients are increased, then the region is transmitted first. The third method is the loseless coding of the ROI. For loseless coding, real number tap cannot be restored perfectly due to the rounding error, so the method of using integers is used. The proposed method shows a better performance than EZW even in case of ROI's PSNR at quality of 40 dB.

In this study, flow of a model intake port/valve system is analyzed by using low Reynolds number $k-{\varepsilon}$ model. Discharge coefficient was obtained from computational results for the various cases of valve lifts. Discharge coefficient becomes maximum when the valve lift is 20mm, and does not increase or decrease in proportional to valve lift. Most of pressure drop and production of turbulent kinetic energy occur at the edge points of the valve and the valve seat Thus, in order to improve discharge coefficient, rounding of edge points in valve and valve seat is recommended. As valve lift is increased, the velocity of the intake jet in the valve passage decreases, and the direction of the jet is more inclined toward the valve seat.

The purpose of this study was to measure patient satisfaction with hosptial foodservices, and thereby identify areas for improvement and provides basic data for the introduction of total quality management into hospital foodservice in the Taegu·Kyungpook area. This survey was carried out on 676 hospitalized patients in 11 hospitals with over 200 beds to determine the quality satisfaction with foodservices. The subjects were 62.4% male and 37.6% female. Sixty-two percent of the subjects were over age 40, 46.7% were only educated to middle school or below, 41.8% were hospitalized for 1 - 10 days. Eighty-seven precent of the subjects did not receive any nutrition education. The expectation and perception grid showed that the high expectation to the low perception items were the seasoning of the meals, taste of the meals, and prompt dealings with meal complaints. The quality satisfaction values of all the attributes indicated a minus. The unsatisfied quality attributes were the opportunity to meet with a dietitian, seasoning of the meals, taste of the meals, explanation of the meals, and prompt dealings with meal complaints. Among the demographic characteristics, age, education, length of admission, and experience with nutrition education produced significant differences in the quality satisfaction scores. In conclusion, it would seem to be desirable that hospital foodservice department introduce selective menus, hygiene education for foodservice employees, standard recipes, quality assurance, and increase the meal rounding of dietitians in the patient foodservice.

This paper describes a design of radix-2 SRT divider unit, which supports IEEE-754 floating-point standard, using redundant binary number system (RBNS). With the RBNS, the partial quotient decision logic can operate about 20-% faster, as well as can be implemented with a simple hardware when compared to the conventional methods based on two's complement arithmetic. By using a new redundant binary adder proposed in this paper, the mantissa divider is efficiently implemented, thus resulting in about 20% smaller area than other works. The divider unit supports double precision format, five exceptions and four rounding modes. It was verified with Verilog HDL and Verilog-XL.

Scorpion venom peptides recently have attracted attention as alternative chemotherapeutic agents that may overcome the limitations of current drugs, providing specific cytotoxicity for cancer cells with an ability to bypass multidrug-resistance mechanisms, additive effects in combination therapy and safety. In the present study, BmKn-2 scorpion venom peptide and its derivatives were chosen for assessment of anticancer activities. BmKn-2 was identified as the most effective against human oral squamous cells carcinoma cell line (HSC-4) by screening assays with an $IC_{50}$ value of $29{\mu}g/ml$. The BmKn-2 peptide killed HSC-4 cells through induction of apoptosis, as confirmed by phase contrast microscopy and RT-PCR techniques. Typical morphological features of apoptosis including cell shrinkage and rounding characteristics were observed in treated HSC-4 cells. The results were further confirmed by increased expression of pro-apoptotic genes such as caspase-3, -7, and -9 but decrease mRNA level of anti-apoptotic BCL-2 in BmKn-2 treated cells, as determined by RT-PCR assay. In summary, the BmKn-2 scorpion venom peptide demonstrates specific membrane binding, growth inhibition and apoptogenic activity against human oral cancer cells.

This study is to grope for a plan to increase nurse's autonomy by grasping autonomy degree according to nursing delivery system. The subject of this study are 265 nurses who work for 4 general hospitals in Seoul, and 73 of them work in primary nursing delivery system, 99 of them in team nursing delivery system and 93 of them in functional nursing delivery system. Data collection was done through questionaires from Sep. 1, 1997 to Sep. 30, 1997, and autonomy was measured by Professional Nursing Autonomy Scale developed by Schutzonhofer. Data analysis as inspected with $X^2$ test, ANOVA, and t-test, using SPSS program. The results are as follows : 1. When it comes to the autonomy of all the nurses, mean score was 161.99. Which is medium level, and autonomy degree according to nursing delivery system had no significant differences. 2. There was a significant difference in autonomy degree according to inservice education among the subject's work-related characteristics, and there was no significant difference in autonomy distribution in each grade according to general characteristics although older group, married group, and junior college graduates group showed rather higher trends. 3. Considering each item, questions related to direct nursing such as "Vital sign monitoring", "Nursing rounding", "Withhold contraindicated drug", showed high score in autonomy scores, and long-term and indirect nursing behaviors such as "Nursing administration", "Nursing research", "Follow-up care" and "Educational planning".
