This study was performed to evaluate the effectiveness of a nutrition education program developed for nutritionally imbalanced adolescents. A summer nutrition camp was held for 23 overweight and 16 underweight subjects. Its effectiveness with regard to was evaluated at the end of the camp and 6 months later. Nutrition knowledge, nutritional attitude, food behavior, nutrient intake, exercise habit and ideal body figures desired by the subjects. The results showed significantly higher nutrition knowledge scores at the end of the camp as compared to those obtained prior to the camp program, and these scores were maintained for at least six months. Nutrition attitude scores also improved after the education program, and these improved scores also lasted for 6 months. However, the food behavior scores measured 6 months after the education program were not significantly different from those obtained prior to the camp. Also, the exercise habit, the ideal body figures and the body figures desired by the subjects remained unchanged. When nutrient intakes of subjects were assessed before the program and 6 months later, the mean daily vitamin C intake was significantly increased after the education program. Also, the intake of iron from plant food sources increased in the overweight subjects, while less iron from animal source were consumed by the underweight subjects. Both groups tended to consume more vegetables and fruits 6 months after the education program which may have contribute to the higher vitamin C and plant-based iron intakes. These results indicate that a 4-day nutrition education camp program sustained changes in nutrition knowledge and nutrition attitude for 6 months. The increased intake of vegetables and fruits was also achieved through this education program. However, changes in dietary behavior in adolescents may require repeated education.

Carcinoid tumors have been reported in a wide range of organs but most commonly involve the lungs, bronchi and gastrointestinal tract. Within the gastrointestinal tract, appendix is the most common location for carcinoid, followed by the distal small intestine, the rectum, and the stomach. Among these, primary involvement of the ampulla of Vater is extremely rare. We report a case of carcinoid tumor of ampulla of Vater. A 62-year-old man presented with epigastric soreness. Gastroduodenal endoscopy showed hyperemic bulging mass on ampulla of Vater and diagnosed as carcinoid tumor by histologic finding, with immunohistochemical study. In ^(111)In-octreoscan, tumor had regional lymph node metastasis, but no evidence of distant metastasis. Pancreatoduodenectomy with lymph node dissection was performed.

In order to understand phytoplankton ecology in the Gulf of Yeong-il, climatic factors such as air-temperature, solar-radiation, evaporation, direction and strength of winds, and precipitation are studied from January 1982 to December 1985. Annual average of air-temperature during the four-years period is about 13.6C, ranging from 1.7C (January) to 26.5C (August). The maximum value of solarradiation is measured in spring (520MJm²in May), the minimun : in winter (62 MJm²in December, January or February), and the total annual value : about 4987MJm². Annual average of evaporation is about 1200mm (Maximum: 169 in May : Minimun: 56 in February), close to precipitation (about 1050mm). Annual average of strength of "North Winds" (350°-90°)is about 550m·sec for 156 frequences during 191 days, "West Winds" (170°-340°) : 511m·sec¹for 185 frequences during 148 days, and "South Winds" (100°-160°) about 61m·sec¹for frequences during 24 days. "N" winds is about 30% more violant than "W" winds, but both winds are influential in terms of water movements in the Gulf.

백주희,이호택,장호균,박병관,이상연,김은경 大韓神經精神醫學會 1999 신경정신의학 Vol.38 No.2

연구목적 : 정신분열증의 인지기능장애가 전반적인 결함인지 아니면 특정한 결함인지 논란이 지속되고 있다. 본 연구에서는 표준화된 신경심리검사 도구인 벤튼 신경심리검사(Benton Neuropsychological Assessment. 이하 BNA)를 사용하여 정신분열병 환자에서 특정한 신경인지기능 결함 유형이 관찰되는지 평가하고자 하였다. 대상 및 방법 : 정신장애 진단통계편람 제4판(DSM-Ⅳ) 진단기중에 따라 분류된 (1) 편집성 정신분열병 입원 환자 30명과 (2) 연령, 성별, 교육정도를 일치시킨 정상 대조군 30명을 연구 대상으로 하여 정신분열병 환자의 임상 증상을 양성 및 음성증상척도(Positive and Negative Syndrome Scale, 이하 PANSS)로 평가하여 인지 결함과 임상 증상간의 상관관계를 검증하였다. 결 과 : BNA 12개 검사(시간지남력 검사, 좌우지남력 검사, 연속숫자학습, 얼굴재인 검사, 직선지남력판단, 시각형태변별 검사, 판토마임재인, 촉각형태지각, 손가락위치판단, 음소변별, 3차원토막구성, 운동지속력 검사)중에서 정신분열병 환자는 정상 대조군에 비해 연속숫자학습(이하 유의수준 p〈0.05), 얼굴재인 검사, 촉각형태지각, 손가락위치판단에서 통계적으로 유의하게 저하된 수행을 보였다. 또한 정신분열병 환자는 정상 대조군에 비해 손가락위치판단 하위 요인 중 오른손, 왼손, 이점역에서 저조한 수행을 보였고, 시각형태변별 검사의 주변오류에서 유의하게 많은 오류를 나타냈다. 정신분열병 환자군에서 PANSS 총점, 양성 및 음성증상척도도 점수와 각 검사, 하위 요인, 오류 점수간에는 유의한 상관관계가 나타나지 않았다. 결 론 : 정신분열병 환자군에서 임상증상과 독립적인 언어성 작동기억, 학습, 주의력 및 안면지각기술과 촉각정보처리 등 시각과 촉각 양식의 지각 과제에서 복잡한 감각정보처리의 결함을 보이며, 이러한 신경인지기능 결함 유형은 선행 연구에서 제시된 특정한 결함 유형과 최소한 부분적으로 일치되는 소견이다. 한편 정신분열병 환자가 대상 위치검사에서는 상대적으로 정상적인 수행을 보인 반면 대상 인식검사에서는 결함을 나타냈으며, 언어성 작동기억이 결함을 보인 결과는.

Objectives : Schizophrenic patients have been reported to be associated with abnormal performance on a broad range of neuropsychological tests. But it has been a persistent controversy in the neuropsychology of schizophrenia whether this disorder is characterized by generalized deficits or specific deficits. The purpose of this study was to investigate, using standardized Benton Neuropsychological Assessment(BNA), whether the specific pattern of neurocognitive deficits is found in schizophrenics. Methods : The subjects were composed of (1) 30 schizophrenic inpatients who were diagnosed as paranoid subtype according to DSM-Ⅳ diagnostic criterior and (2) 30 normal subjects with matching demographic variables(i. e. age, sex, educational level). All tests of BNA were given schizophrenic patients and normal subjects, and the performances of schizophrenic patients and normal subjects were compared on all aspects of BNA. Schizophrenic symptoms were assessed via Positive and Negative Syndrome Scale(PANSS) to determine the relationship between clinical symptoms and schizophrenic cognitive deficits. Results : Of 12 tests of BNA, schizophrenic patients performance on Serial Digit Learning (SDL), Facial Recognition Test(FR), Tactile Form Perception(TFP), Finger Localization(FL) were significantly lower than those of normal subjects. In addition, schizophrenic patients showed significantly lower performances than those of normal subjects on Right Hand, Left Hand, Identification of two simultaneously touched fingers of FL, and more Peripheral Error on Visual Form Perception Test(VFPT). Finally, no significant correlation was found with respect to the relationships between total scores, positive symptoms scores, negative symptoms scores of PANSS, and all scores of BNA tests in schizophrenic patients. Conclusion : These results suggest that schizophrenic patients may have a specific pattern of neurocognitive deficits in verbal working memory, learning, attention, and complex sensory information processing in visual and haptic modality such as facial perception skills, tactile information processing, independent of psychotic symptoms. The pattern of deifcits is at least in partial, in agreement with many previous study results. On the tests of linguistic functions, visuospatial perception, and constructional abilities, schizophrenic patients' performance were not significantly different from those of normal subjects. The findings on visuospatial perception and constructional abilities imply that some posterior cortical zones may be relatively uncompromised in schizophrenia. Both poor performances on object recognition tests relative to normal performances on object location tests and verbal working memory dysfunction may be associated with the putative dysfunction of the reciprocal connections either (1) between the prefrontal and parietal cortex or (2) between the prefrontal cortex and hippocampal formation. This tentative explanation remains to be confirmed.

In this study, we analyzed the characteristics of atmospheric stability to investigate local environment change at an atomic power plant in Gori region. The used data was obtained from field observation of major meteorological variables such as wind direction and speed, air temperature, relative humidity, and solar radiation using AWS (Automatic Weather System) in Gori region from February to September in 2003. As a result, when strong northerly winds (more than 4~6 m/s) and weak northwesterly winds (2~3m/s) blow, atmospheric stability was neutral and stable from winter to spring, respectively. Atmospheric stability (neutral) in summer was similar to that in two other seasons (winter and spring), but it was stable for weak southwesterly winds (2~3 m/s). Finally, atmospheric stability was neutral for strong winds (over 4~6 m/s) in fall without respect to wind direction, while that was stable for very weak winds (less than 2 m/s).

The purpose of this study was to compare the fracture resistance of the IPS Empress ceramic crown with 1.0mm width rounded shoulder, which is usually recommended in all ceramic crown, and 0.5mm width chamfer finish lines on the maxillary first premolar. 30 sound maxillary first premolars were selected and then storaged in 5% NaOCl and saline. 15 teeth were performed preparation for each group(1.0mm rounded shoulder, 0.5mm chamfer). After 30 stone dies were made for each group, the IPS Empress ceramic crowns were fabricated and cemented with resin cement(Bistite resin cement, Tokuyama Soda Co. LTD., Japan) on the natural teeth. The cemented crowns were mounted on the positioning jig and the universal testing machine(Zwick Z020, Zwick Co., Germany)was used to measure the fracture strength, with stress loading on the occlusal surface between buccal and lingual cusp. And also, three-dimensional finite element model was used to measure the stress distribution with two types of the finish lines(1.0mm rounded shoulder, 0.5mm chamfer) and two loading conditions(both buccal and lingual cusp inclination, lingual cusp inclination only). The result of the this study were as follows. 1. In the fracture resistance experiment according to the finish line, the mean fracture strength of rounded shoulder(842N) showed higher value than that of the chamfer(590N) (p<0.05). 2. In the three dimensional finite element analysis of all ceramic crown, metal die and natural teeth model did not show any differences in stress distribution between finish lines. 3. Generally, when force was loaded on the occlusal inclination of buccal and lingual cusp, the stress was concentrated on the loading point and the central groove of occlusal surface. 4. When force was loaded only on the occlusal inclination of lingual cusp, the stress was concentrated on the lingual finish line and loading point.
