  • As the measurement of strain-gage type cone penetrometer is influenced by the temperature change during penetration, the temperature is a factor producing an error of the cone tip resistance. In this study, the 0.5 mm diameter temperature transducer and 7 mm diameter micro cone penetrometer are manufactured by using FBG sensors to evaluate the effect of temperature on the cone tip resistance. Design concepts include the cone configuration, sensor installation and the temperature compensation process. The test shows that the tip resistance measured by strain gauge is affected by the temperature change. The error of the tip resistance increases with an increase in temperature change, while the temperature effect on the tip resistance of FBG cone is effectively compensated by using FBG temperature transducer. Temperature compensated tip resistance of the strain gauge cone shows the good matched profile with FBG cone which performs real-time temperature compensation during penetration. This study demonstrates that the temperature compensation by using FBG sensor is an effective method to produce the more reliable cone tip resistance.

  • Planar antennas are very efficient for the use of the out-door data transmission applications due to their low-profile characteristics. But the size of the antenna in UHF band blocks the practical usage. In this paper, a miniaturized planar antenna is investigated for the application of AMR system in UHF band. The designed antenna is fabricated in the form of the microstrip patch on the FR-4 substrate. The miniaturization is achieved by slot-loading on the patch. First, effects of simple slots on the size reduction are analyzed, followed by the design using more complex slots resulting in the reduction ratio of 37.9% in 425.6 MHz and bandwidth of 3.8 MHz. The effect of epoxy coating for the protection is also investigated.

  • Learning in medical school is usually regarded as a very specialized type of learning compared to that of other academic disciplines. Medical students might have general beliefs about their own learning. Beliefs about learning have a critical effect on learning behavior. There are several factors that affect medical students' learning behavior: epistemological beliefs, learning styles, learning strategies, and learning beliefs. Several studies have addressed epistemological beliefs, learning styles, and learning strategies in medical education. There are, however, few studies that have reported on medical students' beliefs about learning. The purpose of this study was to determine what learning beliefs medical students have, what the causes of these beliefs are, and how medical educators teach students who have such beliefs. In this study, the five learning beliefs are assumed and we considered how these beliefs can affect students' learning behaviors. They include: 1) medical students are expected to learn a large amount of information in a short time. 2) memorization is more important than understanding to survive in medical schools. 3) learning is a competition and work is independent, rather than collaborative. 4) reading textbooks is a heavy burden in medical education. 5) the most effective teaching and learning method is the lecture. These learning beliefs might be the results of various hidden curricula, shared experiences of the former and the present students as a group, and personal experience. Some learning beliefs may negatively affect students' learning. In conclusion, the implications of medical students' learning beliefs are significant and indicate that students and educators can benefit from opportunities that make students' beliefs about learning more conscious.

  • When women are removed with their matrix which is a emotionally significant organ of symbol in psychologically adapting themselves to mother and woman, that is threatened and injured with woman role decisively. This study tried to find the efficient nursing intervention method to maintain and promote their health, to cope with health problem, and to inquire into the loss experience of women with hysterectomy by using the phenomenological method. The analysis of the data was made through the phenomenological analytic method suggested by Giorgi. The result of the study was as follows : The factors which have influence on the loss experience of the subjects are an offer of information, support system, age, occupation, economic situation, family history, character, season, the existence of ovary and religion. The loss experience of matrix was expressed in lingual, reactions to the loss of function, sex, body change and husband, in behavioral behaviors in emotion and body. The loss of matrix of the subjects was relived by religion. perineorrhapy, exercise, reading, watching video and diet. The subjects each showed ways of reaction of fatalism, giving-up, coping on the loss experience of matrix. In conclusion, since we ascertained that the nursing in the process of recovery decide the quality of life. though women with hysterectomy undergo various loss experience and adapt to it in the end, it is necessary to give them enough information and educate husband, having on important effect on the loss experience, to be a good supporter, And technically skilled nurses of consultant are thought to be able to contrive better qualitative life of women with hysterectomy as an important bridge between the subjects and their required information, since the nurses have their well-formed position of relationship of confidence through continuous contact with patients and their family.

  • To find axial and lateral responses of impact-driven H piles in embankment(SM), the H piles are instrumented with electric strain gages, dynamic load test is performed during driving, and then the damage of strain gages is checked simultaneously. Axially and laterally static load tests are performed on the same piles after one to nine days as well. Then load-settlement behavior is measured. Furthermore, to find the set-up effect in H pile, No. 4, 16, 26, and R6 piles are restriked about 1, 2, and 14 days after driving. As results, ram height and pile capacity obtained from impact driving control method become 80cm and 210.3∼242.3ton, respectively. At 15 days after driving, allowable bearing capacity by CAPWAP analysis, which 2.5 of the factor of safety is applied for ultimate bearing capacity, increases 10.8%. Ultimate bearing capacity obtained from axially static load test is 306∼338ton. This capacity is 68.5∼75.7% at yield force of pile material and is 4∼4.5 times of design load. Allowable bearing capacity using 2 of the factor of safety is 153∼169ton. Initial stiffness response of the pile is 27.5ton/mm. As the lateral load increases, the horizontal load-settlement behaves linearly to which the lateral load reaches up to 17ton. This reason is filled with sand in the cavity formed between flange and web during pile driving. As the result of reading with electric strain gages, flange material of pile is yielded at 19ton in horizontal load. Thus allowable load of this pile material is 9.5ton when the factor of safety is 2.0. Allowable lateral displacement of this pile corresponding to this load is 23∼36mm in embankment.

  • Stewed pumpkin juice(SPJ) has recently become popular as a health drink, and its consumption is growing rapidly. Well ripened pumpkin was heated in a pressure cooker and squeezed to an extract and then packed in retort pouches. The ingredient of ginger, onion, jujube and boxthorn was added to samples of SPJ in order to observe the effect on the composition of SPJ during production and storage at 28oC for 60 days. The level of the main mineral(K) in pumpkin varied when the ingredients were added. The pH of control SPJ showed more changes than the SPJs with ingredients added, and there was almost no change in the samples with boxthorn. During storage, titrable acidity decreased in all samples, and the SPJs with ginger and jujube showed relatively little change compared to the samples of control SPJ and SPJ with onion. As for soluble solid and reducting sugar, the SPJs with jujube and boxthorn showed the highest reading. For carotenoid, the SPJs with jujube, ginger, boxthorn and onion listed according to the amount of carotenoid contained more total carotenoid than the control SPJ. Most of the carotenoid in pumpkin and its extract was found to be carotene by HPLC and Chandler's method. Sensory evaluation of the SPJ samples with ingredients revealed preference for the taste of the SPJs with jujube, ginger and boxthorn in declining order of preference. The taste of SPJs with ingredients added was generally preferent over the control SPJ except the case of SPJ with onion.

  • The purpose of this study was to investigate compensatory consumption propensity by male and female college students. The subjects of the study were 483 college students in Seoul, and SPSS 12.0 was used for statistical analysis. Two different types of compensatory consumption were considered separately positive compensatory consumption and negative compensatory consumption. The major findings were as follows. First, for male college students, drinking was the most preferable means of compensatory consumption to compensate for both negative and positive emotions. For female college students, their consumption patterns tended to include clothing purchase and eating-out for positive emotions and eating-out, reading and drinking for compensating negative emotions. Second, for both male and female students, the consumption propensity for compensating positive emotion was found to be higher than that for compensating negative emotion. And the consumption propensities for compensating positive and negative emotions were higher for female students when compared to those of male students. According to the results of regression analysis showing the relative effect of each variable to compensatory consumption, sex and consumption tendency were found to be relative variables on both positive and negative compensatory consumptions. Female students were found to be more likely to consume for compensating emotion than male students after other variables were controlled. For positive compensatory consumption, consumption propensity and materialism were found to be the most effective variables, and for negative compensatory consumption, materialism was the most effective variable.
