Purpose: The purpose of this pilot study was to investigate the effects of mechanical interventions for deep vein thrombosis (DVT) prophylaxis in surgical intensive care unit (SICU) patients. Methods: The participants were assigned to the intermittent pneumatic compression (IPC) and graduated compression stocking (GCS) intervention. Patients who met the criteria were selected for comparison from our previous study. Data for 140 patients were included in the final analysis. Results: The mean age was 57.5 (±15.7) and 61.4 % were men. About forty-seven percent of the participants were 61 years or over. In the second duplex scan, 3, 2 and 1 critically ill patients developed deep vein thrombosis in the control, GCS, and IPC groups, respectively. Incidences of DVT were 6.0%, 5.0%, and 2.0% for the control, GCS, and IPC groups, respectively. This difference was not significant. Relative risks of no intervention were 3.0 and 1.2 compared with IPC and GCS application. There were no significantly different variables among the three groups before the intervention except for diagnosis on admission. Conclusion: Although it may difficult to conclude that mechanical prophylaxis effectively prevents DVT among SICU patients because there was no statistical significance in this study, but incidence rates among the three groups differed greatly. The findings reveal that further study should be conducted with larger samples and randomized controlled trial for SICU patients.

Objectives The purpose of this study is to get the basic information from patients how much they understood about their medication and also to know whether patients are making reasonable drug choice between Health Functional Foods and Herbal medicine. Methods 500 questionnaires were handed out to the parents of students in two elementary schools located in OO, Junlabukdo province. 421 questionnaires were completed to be evaluated. Results Among 421 subjects, 53.0% were female, and 47.0% were male. The percentages of the subjects consuming Health Functional Foods and herbal medicine were67.7% and 67.8%, respectively. Among those people who consumed Health Functional Food, 44.1% were using nutritional supplements, red ginseng or ginseng products (26.9%), chlorella products (11.5%), and plum extract products (7.7%). As for the reason to consume Health Functional Foods were varied, but 'in order to be healthy, although currently displaying no illness.'(43.0%) were the most responses among the given choices. On the other hand, the reason for consuming herbal medicine was 'In order to grow taller'(26.1%), 'In order to cure weak physical state frequently displaying common illnesses',(25.9%), and 'In order to cure diseases.'(23.3%). For the questions about effectiveness after consumption,the 69.9% subjects said that it seemed to be effected, and that % was slightly higher than that of subjects with consuming Health Functional Foods(64.4%). For question concerning preferences between Health Functional Foods and herbal medicine, 57.5% chose herbal medicine, and this percentage was higher than that of Health Functional Foods(42.5%).As for the reasons of additional consumption of the Health Functional Foods, subject answered as 'Easy to consume.'(41,6%), which was the most common among the subjects consuming Health Functional Foods. On other hand, the subjects of herbal medicine answered as that herbal medicine is 'more effective'(45.7%), and 'more trustworthy in preventing side-effects.'(40.3%). After consumption of the herbal medication, only 3.9% of the subjects consuming either Health Functional Foods or herbal medicine had side-effects. The most common side-effects were 'dermal reaction' which is normally caused by Health Functional Foods and 'indigestion' problems caused by herbal consumption. Conclusions According to the 421 subjects those involved in study, the percentages of consuming Health Functional Foods(67.7%) and herbal medicine(67.8%) were similar. The most commonly consumed products were a type of Health Functional Foods which were the nutrition-supplying products. Ginseng or red ginseng products were the next commonly used products. Health Functional Foods were commonly consumed for preventing illness and maintaining health rather than any other purpose. In contrary, herbal medicines were more commonly consumed for purposes such as for growth or treating certain type of disease. As a result of consumption, more than half of both subject replied as 'satisfied'. As for the side effects, dermal reaction was the most common problem for those with consuming Health Functional Foods, while indigestion was the most common side effect from the subjects with consuming herbal medicine.

The structure changes of the vocal folds are related to the fundamental frequencies (F0). In other words, the increasing in vocal fold length and thickness makes the result of dropping in the F0 during the mutational period. The purpose of this study was to investigate F0 of normal children's voice in mutational period. 360 children (180 boys and 180 girls) were participated in this experiment. The age was ranged from 11 to 16 years. The subjects were asked to produce sustained corner vowels (/a/ /i/ /u/) five times each and the data were analyzed using the MDVP of CSL. The result shows that the F0 are considerably decreased with age and reach to adults' F0 by 16 years in most cases. In particular, the F0 of male subjects were rapidly decreased between the ages from 12 (226.98 ± 19 Hz) to 13 years (169.3 ± 25 Hz), while the F0 of female subjects were slowly changed from the later period of 12 to 16 years old. This result may be used by the meaning of guideline and lead the basic data to differentiate between normal voice and voice disorder.

Multiple physical changes of the larynx and its components occur with age. Vocal pitch, commonly expressed through measures of fundamental frequency (Fo) relate to physical conditions of the larynx. Available data is lacking for the senescent voice, and should be applied to the of changes of elderly speakers' Fo characteristics. The purpose of this study was to investigate the Fo of normal elderly speaker‘s voice. A total of 406 normal elderly speakers (207 males and 199 females) participated in this experiment. Age ranged from 60 years to 89 years. The subjects were asked to produce sustained corner vowels (/a/ /i/ /u/) three times each and the data were analyzed using the MDVP of CSL. According to the results of this study, the mean Fo from the ages of 60's to 80's shows 143.95Hz(SD 13.94) for men and 185.42Hz (SD 15.29) for women. For men, a significant change is found as a function of age in the Fo (F=16.181, p<.05). A post-hoc Scheffe test revealed significant differences between the Fo data of subjects aged 60's and 70's, 60's and 80's. For women, a significant change is found as a function of age in the Fo (F=49.013, p<.05). A post-hoc Scheff?e test revealed significant differences between the Fo data of subjects in their 60's and 70's, 70's and 80's, 60's and 80's. The Fo of men goes up from their 60's to 80's gradually, whereas the Fo of women goes down gradually until their 70's, and after their 70's it again increases. It has been known that diminishing estrogen levels in women in old age may be a factor in lowering Fo, whereas diminishing testosterone levels in men may contribute to a rising Fo. This result may be used as some meaningful guideline and lead the basic data to differentiate between normal aged voice and aged voice disorders.

This study investigates the use of gestures in children with Down Syndrome using CSBS by Wetherby & Prizant (1993). Ten children with Down Syndrome participated in this study as an experimental group, and ten children with normal development, as a control group. Frequency, rate, and type of gestures used were coded. The data were analyzed by descriptive statistics and a t-test in SPSS (version 10). The results of the present study can be summarized as follows: (1) Normal children used 2.0 gestures per minute and children with Down Syndrome used 3.5 gestures per minute. Thus, children with Down Syndrome used a high frequency in average number of gestures than children with normal development. There were significant differences between the groups in the total number of gestures (p< .05). (2) In the rate of gesturing, children with normal development made the most use of conventional gestures(90.7%). On the other hand, children with Down Syndrome used a much lower rate of conventional gestures(64.2%). It revealed that children with Down Syndrome used various high-level and richer-repertoire gestures than the control group. This result is consistent with previous studies. It was shown that symbolic gestures and combined gestures and joking were used only by children with Down Syndrome. In conclusion, predominant use of gestures by the children with Down Syndrome explains that these children have difficulty in language production. However, this study does not show a relation between gestures and language. 이 연구는 다운증후군아동의 제스츄어 사용을 살펴보기 위해 구조화된 상황에서 제스츄어 사용빈도, 제스츄어 유형에 따른 사용비율을 표현언어를 일치시킨 대조군과 비교하였다. 제스츄어 유형은 관습적 제스츄어, 원거리 제스츄어, 상징적 제스츄어, 제스츄어 조합, 장난하기, 말하기(말이 동반된 제스츄어), 기타로 분류하였다. 제스츄어 사용빈도는 다운증후군아동이 대조군에 비해 유의하게 높게 나타났다(p<.05). 제스츄어 유형에 따른 사용비율은 대조군이 90.7%로 거의 관습적 제스츄어만을 사용하는 반면, 다운증후군아동의 관습적 제스츄어의 사용이 64.2%로 상대적으로 낮고 관습적 제스츄어 이외에 발달된 수준의 다양한 제스츄어를 사용하는 것으로 나타났다. 특히 상징적 제스츄어, 제스츄어 조합, 장난하기는 다운증후군아동에게만 나타났다. 결과는 다운증후군아동의 언어발달 특성으로 구어적 의사소통의 어려움과 제스츄어 사용능력을 설명하는 근거가 되고, 이를 반영한 평가와 교육의 필요성을 시사한다.

Nonlinear I-V Characteristics of Ta2O5-, Nb2O5-, V2O5-Doped SnO2 Based Varistor Ceramics

HAI JOON LEE,김일원,CHANG DO KIM,정귀상,이재신,SUN HEE KANG 한국물리학회 2007 THE JOURNAL OF THE KOREAN PHYSICAL SOCIETY Vol.51 No.2I

The influence of doping on the nonlinear electric properties of Nb$_{2}$O$_{5}$, Ta$_{2}$O$_{5}$, V$_{2}$O$_{5}$ doped SnO$_{2}$+CoO+ZnO varistor ceramics has been studied by measuring the nonlinear coefficient, the breakdown field, the barrier height and ac conductivity as functions of the temperature, the electric field and the frequency. The un-doped SCZ ceramics showed varistor characteristics, such as a nonlinear coefficient ($\alpha$ = 2.94) and breakdown electric field ($E$$_{B}$ = 1760 V/cm) at the room temperature. The Ta$_{2}$O$_{5}$ and V$_{2}$O$_{5}$ doped SCZ:Ta and SCZ:V ceramics displayed no varistor characteristics at the room temperature. However, the Nb$_{2}$O$_{5}$ doped SCZ:Nb ceramics exhibited enhanced varistor characteristics ($\alpha$ = 17.2, $E$$_{B}$ = 5064 V/cm) at the room temperature. The advanced varistor characteristics of SCZ:Nb ceramics can be explained by the formation of oxygen species, such as O$^{\prime}$, O$^{\prime\prime}$.

We acquired and interpreted more than 650 km of high-resolution seismic reflection profiles in the Hupo Basin, offshore east coast of Korea at 37˚N in the East Sea (Japan Sea) to image shallow and basement deformation. The seismic profiles reveal that the main depocenter of the Hupo Basin in the study area is bounded by the large offset Hupo Fault on the east and an antithetic fault on the west; however, the antithetic fault is much smaller both in horizontal extension and in vertical displacement than the Hupo Fault. Sediment infill in the Hupo Basin consists of syn-rift (late Oligocene-early Miocene) and post-rift (middle Miocene-Holocene) units. The Hupo Fault and other faults newly defined in the Hupo Basin strike dominantly north and show a sense of normal displacement. Considering that the East Sea has been subjected to compression since the middle Miocene, we interpret that these normal faults were created during continental rifting in late Oligocene to early Miocene times. We suggest that the current ENE direction of maximum principal compressive stress observed in and around the Korean peninsula associated with the motion of the Amurian Plate induces the faults in the Hupo Basin to have reverse and right-lateral, strike-slip motion, when reactivated. A recent earthquake positioned on the Hupo Fault indicates that in the study area and possibly further in the eastern Korean margin, earthquakes would occur on the faults created during continental rifting in the Tertiary

54 unipolar pmstheses and 61 bipolar prostheses with same femoral stem were examined clinically and radiologically at an average of 34 months postoperatively. The average age of the patients in unipolar group was 74 years and 71 years in bipolar group. All prostheses had been inserted due to femoral neck fractures. There were two cases of dislocations, two cases of acetabular erosion in unipolar group and bipolar group, respectively. Dislocated prosthetic head was reduced with closed method in unipolar group, meanwhile open reduction was required in bipolar group. One case of early failure was found in cemented bipolar arthroplasty at post-op 2 years follow-up. Functionally, the results were excellent and good in 70.4% of unipolar group and in 73.8% of bipolar group. There was no significant difference between unipolar and bipolar arthoplasty.
