This study was carried out to find the factors which are related to the weight gain during pregnancy of women and infant birth weight. The information of the general characteristics and pregnancy outcomes of the 506 women who had a delivery during Jan to Dec. 1997 in a hospital at Taegu area were collected from the medical records. The results are as follows. The mean age of the subjects was 29 years old and the average prepregnancy weight was 52.75㎏. They gained 13.51㎏ of weight during the pregnancy. The weight gain during pregnancy was higher in prepregnancy BMI <20kg/m^(2), the infant weight was heavier in groups that had over 14kg of weight gain during the pregnancy than other groups. The prepregnancy BMI was negatively correlated to weight gain during pregnancy (r=0.2825), and positively correlated to number of pregnancy (r=0.2146), number of living delivery (r=0.1409), and infant weight (r=0.1250). The baby weight was positively correlated to weight gain during pregnancy (r=0.1392) and Apgar score(r=0.1627). The results showed that the prepregnancy BMI and weight gain during pregnancy may be the influential factors on the infant weight, thus we need to develop the specific nutritional management program according to the status of prepregnancy weight.

In this paper, we propose the design of the application server which provides internet services for the mobile devices such as a mobile phone and PDA, etc. The neutral form of mobile application which can be requested by various kinds of mobile devices is created and deployed to the proposed application server. The mobile application server supplies the content transformed according to the constraints and features of a mobile device. By using the server, a user can use many kinds of mobile devices at the same time, and only one session can be created and maintained at the server. The mobile application server is composed of the tree modules: Mobile Request Generator, Mobile Engine, and Environmental Adoptation module. The Mobile Request Generator module receives the mobile request from a mobile device and creates the mobile request information supplied to the Mobile Engine module. The Mobile Engine module processes the mobile application requested and creates a content which will be sent to a mobile device. The Environmental Adaptation module transforms the output of Mobile Engine into the contents that a mobile device can display. In this way, the proposed mobile application server can support various kinds of mobile devices using a neutral form of internet service.

This sty was undertaken to explore the utilization patterns of medical treatment and herb medicine in patients with arthrits. The data were collected from 995 patients who were registered either in a center of rheumatology or resided in community with arthritis. The data were analyzed by percentile, t-test and chi-square test using SAS PC program. The results of this study were as follows; 1. According to characteristics of sample-population, mean age was 57.7 years, duration of arthritis 9.7 years and mean duration of pain 2.4 hours per day at present. 2. First diagnosis was identified at department of orthopedic surgery or local clinic. But 85.2% of patients have transferred to the center of reumatology currently. But ironically over 70% of patients experienced the herb treatment and herb treatment had hern medicine simultaneous with medical treatment. This indicated that they were shopping around of treatment during the first one year. 3. Mean cost of medical treatment was 67,400 won, while they payed to herb medicine as much as two or three times. The utilization rate of herb medicine was 36.5% of patients per one year. Costs of herb-treatment were 182,000 Won and herb medicine was 36.6% of patients per one year. Costs of herb -treatment were 182,000 Won and herb medicine 149,100 Won. 4. Eighty point six percent of patients were experienced herb medicine during life-time. One hundred and seventy four kinds herb medicine were found to be used by patients, most of which were nutrients, muscle relaxants, andtiphlogistics and analgesics. Thirty two point six percent of users recognized that herb medicine were effective but 51.7% did not. In conclusion, arthritis patients have been experienced various kinds of drug and remedies for treatment. And they wasted their limited medical and economical resources on these unresonable remedies. Therefore, they should be guided for wise decision about treatment. Futher studies in nursing will be required to explore the value system of patients about herb medicine, the determinant factors of shopping-around patterns of treatment, and the coping mechanism for chronic pain or aggravating symptom.

바나듐이 도핑된 강유전체 Bi₄Ti₃O_12 박막(BTV)의 성장과 특성

정원태,최은경,김현주,강민진,김상수 昌原大學校 基礎科學硏究所 2001 基礎科學硏究所論文集 Vol.13 No.-

Bi3.99Ti2.97V0.03O12 (BTV) thin films with 3 mol% vanadium doping were prepared on Pt/Ti/SiO2/Si substrate by sol-gel method. X-ray diffraction analysis indicated that single-phase lapered perovskite were obtained and preferred orientation was not observed. Under the annealing temperature at 600℃, the surface morphology of the BTV thin films had fine-rounded particles and then changed plate-like at 650℃ and 700℃. The remanent polarization (2Pr) and coercive field (2Ec) of 700℃ annealed BTV thin film were 25 μC/cm2 and 116 kV/cm, respectively. In addition, BTV thin film showed little polarization fatigue during 109 switching cycles. These improved ferroelectric properties were attributed to the increased rattling space and reduced oxygen vacancies by substitution Ti4+ ion (68 pm) with smaller V5+ ion (59 pm). The dielectric constant and loss were measured 130 and 0.03 at 10 kHz, respectively.

온톨로지는 시멘틱 웹을 구현하기 위한 이론이다. 온톨로지는 웹자원의 효과적인 검색, 통합, 재사용을 위한 새로운 기술이고 사람과 이질의 응용 시스템 간에 지식을 공유하고 재사용하기 위한 방법을 제공한다. 온톨로지의 역할은 특별한 개념을 명세화하는 것이다. 도메인과 일반적인 온톨로지는 정보와 지식 시스템을 분석하고 디자인하는 측면에서 공유, 통합, 재사용될 수 있다. 본 연구는 제주도의 숙박과 관광정보를 위한 온톨로지를 디자인하는데 목적이 있다. 그리고 제안된 온톨로지 기반으로 인터넷 웹 검색 시스템을 만드는데 목적이 있다. 본 연구에 의해 클라이언트가 사용하는 표현은 다르지만 뜻이 같은 동의어에 의해 같은 결과를 얻을 수 있다는 것을 알게 되었다. Ontologies are formal theories that are suitable for implementing the semantic web. Which is a new technology that attempts to achieve effective retrieval, integration, and reuse of web resources. Ontologies provide a way of sharing and reusing the knowledge among the people and the heterogeneous application systems. The role of ontologies is that of making explicit specified conceptualizations. In this context, domain and generic ontologies can be shared, reused, and integrated in the analysis and design stage of information and knowledge systems. This study aims to design an ontology for juju lodges and tour, and build an Internet web retrieval system based on the proposed ontologies. This study found that we can take the same result for synonym that cilent use.

The aim of this study was to evaluate the effects of 3D-Relax Diet; a proprietary formation containing hydroxycitrate(233mg/g), carnitine(150mg/g); and capsaicin (150mg/g); on body weight, % body fat, fat mass, lean body mass, Resting Metabolic Rate(RMR), body circumference, skinfold thickness, serum glucose and lipid level. Nineteen female college students participated in this 4 weeks weight control program. All subjects were randomly assigned to the Sang sik(S) group or Sang sik & 3D-Relax(3D) group. Mean energy intake of 3D group was l,523.1±300.2 ㎉(carbohydrate: 66.3%, protein: 18.7%, fat: 15.0%) and S group consumed 1,464.8±142.1 ㎉(carbohydrate: 65.1%, protein: 19.0%, fat: 15.9%) during program. The 3D group lost 3.1±1.3 kg of body weight, 2.5±l.4 kg of fat mass, 0.6±1.2 kg of lean body mass and 16.8±183.3 ㎉/d of RMR and the S group lost 1.8±1.0 kg of body weight, 1.1±1.1 kg of fat mass, 0.8±0.3 kg of lean body mass and 19.1±181.9 ㎉/d of RMR. There was no significant differences in the loss of lean body mass and RMR between two groups, however, the total body weight and the fat mass were significantly decreased in the 3D group compared to the S group(p<0.05). The 3D group experienced a significant reduced hip size, total-cholesterol and HDL-cholesterol, however, the change of these between groups were not significantly different. There were no differences in the change of body circumference, skinfold thickness, serum glucose and lipid. These results suggest that the intake of 3D-Relax Diet(hydroxycitrate, carnitine, and capsaicin) during the weight control program decreased energy intake, fat intake and total body weight especially fat mass and those effects are presumably linked to the prevention of RMR decline and the inhibitory effects on lipogenesis.

The purpose of this study was to examine the effects of vitamin D₃and retinoic acid on the growth and osteogenic differentiations of the human mesenchymal stem cells(MSC). Cell proliferation rate was determined by MTT assay, mineralization assay was determined by alizarin red stain, cell cycle analysis was done by flow cytometry, p53, pRb, p21, BMP-2 and BSP were detected by Western blot analysis. The observed results were as follows. 1. Cell viability was decreased by vitamin D₃ or retinoic acid(RA) added to MSC, it was more decreased by mixed treatment of vitamin D₃ and RA(p<0.05). 2. The pattern of mineralized nudule formation was similar to the positive control group at 3 weeks in mixed treatment of vitamin D₃ and RA. 3. In mixed treatment of vitamin D₃ and RA, G1 stage was increased in 7 days of incubation, cell cycle progress was inhibited in 21 days of incubation as the increase of apoptosis. 4. Treatment vitamin D₃ inhibited the expression of p53 and p21, but increased that of pRb(phosphotylated retinoblastoma). Treatment of RA or mix of RA and vitamin D₃ inhibited the expression of p53, increased those of p21 and pRb. 5. The expression of BMP-2 was prominent in treated group of osteogenic supplement at 2 weeks, but vitamin D₃ decreased the expression of BMP-2 expression. Treatment of RA or mix of RA andvitamin D₃ showed the similar expression to that of negative control, but in 3 weeks, no significant difference was shown between control and experimental groups. 6. BSP was notably increased in the osteogenic supplement(0S) in comparison to positive control at 2 weeks, but treatment of vitamin D₃ showed the similar expression to the control group, treatment of RA or mix of RA and vitamin D₃ showed the least expression. These results suggested that vitamin D₃ and RA took the differential effects on the growth and differentiation of MSCs .

Dept. of Neuro-Psychiatry, Keimyung University Medical School and Hospital, Taegu, Korea. The authors conducted a statistical study of 443 elderly patients who had visitea the Neuro-Psychiatrc department, Keimyung University Hospital for the past 17 years from 1965 to 1981, and they were older than 60 years of age at the time of their first visit. The results are summarized as follows: 1. Of the total psychiatric patients who visited the hospital during the period of 1965 to 1981, the elderly patients were 2.70% and of inpatients were 1.62% of the total inpatients, 2. Of the clinical diagnoses, neurosis was the most common (42.3%), followed by organic brain syndromes and functional psychoses. 3. Female patients outnumbered male in neurosis, whereas male patients outnumbered female in organic brain syndromes. 4. Organic brain syndromes were consisted of senile psychosis(27.9%), cerebral arteriosclerosis (21.2%). alcoholic psychosis (14.5%), and sequella of CO intoxication (12.7%), in its descending order. 5. Among the functional psychoses, involutional melancholia and psychotic depressive reaction were the most frequently found in about three fourths, and the others such as schizophrenia and paranoid state were about 10 percent respectively. 6. Of the associated physical illnesses, cardiovascular and eye and E.N.T. diseases were most frequent. The frequency of cardiovaschular, respiratory, and genitourinary diseases were directly proportional to the increasing age of the patients. 7. Considering the duration of treament, two thirds were treated in the neuropsychiatric service for lesser than a month, and the average duration was 76.8 days, 8. Elderly inpatients: a. Male patients where almost two times that of female ones. b. Among the clinical diagnoses, organic brain syndromes and functional psychoses were most common. c. Average duration of hospitalization was 26.8 days, and the longest was functional psychosis lasting 50.8 days. d. Overall hospitalization treatment brought recovery rate of 44.4%, and the functional disorders showed higher recovery rate than that of the organic brain syndromes.

이은숙,이영철,정지영,윤종훈,김창수,손병기,이흥락 경북대학교 센서기술연구소 1995 센서技術學術大會論文集 Vol.6 No.1

A FET type micro CO_(2) sensor based on a Severinghaus type arrangement has been prepared and its response characteristics were examined. The sensor was fabricated by formation of hydrogel layer containing bicarbonate/chloride ions on the PH-ISFET and the Ag/AgCl reference electrode prepared by the thermal evaporation and chemical chloridation methods. And then gas-permeable membrane was dip-coated on the hydrogel layer of the sensor. Gas-permeable membranes were fabricated with silicon rubber and polyurethane dissolved in toluene and THF, respectively. The CO_(2) sensor with the silicon rubber membrane showed better sensitivity and lower detection limit than the CO_(2) sensor with the polyurethane membrane for dissolved CO_(2). The sensor with silicon rubber membrane at optimal conditions showed a good response: linear range of 1.60X10^(-4) ~ 4.40X10^(-2) M CO_(2), sensitivity of 57.30 mV/decade, and detection limit of 7.50x10^(-4) M.

소은희,정유숙 大韓神經精神醫學會 1992 신경정신의학 Vol.31 No.3

Korean version of the Childhood Autism Rating Scale(CARS) ws used with 41 developmentally disabled children under age 11. Cronbach's coefficient alpha was 0.94. The interrater reliability(γ) for each of the 15 scales ranged from 0.61 to 0.92 with an average of 0.76. The total GARS score or number of item above 3 score demonstrated a statistically significant correlation with social age. But the total CARS score or number of item above 3 score demonstrated an unsatisfactory correlation with social quotients. The authors suggest that the development of assessmental instrument for infantile autism and concurrent use of Krug's “Autism Behavior Checklist” will be needed.
