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.

Objectives : The aim of this study was to examine the behavioral and emotional problems associated with nocturnal enuresis in Korean children. Methods : Three hundred eighteen children with nocturnal enuresis, together with their parents, completed the Child Behavior Checklist (CBCL), Disruptive Behavior Disorder Scale according to DSM-IV (DBDS), Children's Depression Inventory (CDI), State-Trait Anxiety Inventory for Children (STAIC), and Piers-Harris Children's Self-Concept Scale (PHCSC). Ninety-three normal students were selected as the control group. Results : Compared to the normal control group, the mean scores with regard to the withdrawn, social problems, attention problems, delinquent behavior, aggressive behavior, externalizing problems and total problems profiles were significantly higher in the nocturnal enuresis group according to the CBCL results. The nocturnal enuresis group also scored significantly higher in the ADHD and ODD profiles of the DBDS. The nocturnal enuresis group was more depressed and anxious than the control group according to the results of the CDI and STAI. The mean score of the PHCSC was significantly lower in the nocturnal enuresis group when compared to the normal control group. Conclusion : The results of this study suggest that children with nocturnal enuresis in Korea have clinically relevant behavioral and emotional problems. The findings support the link between nocturnal enuresis and psychopathology in Korean children.

Ethanol Patch Test와 음주 후 불편감과의 관계에 대한 연구

신재정,장환일,김경빈 大韓神經精神醫學會 1989 신경정신의학 Vol.28 No.1

It has been well known that alcoholism is influenced by multiple factors such as biological, social and familial factors. Recently many researches are focusing on further investigation of biological aspects, especially on enzymes of acetaldehyde metabolism. The low Km aldehyde dehydrogenase(ALDH-I) has been implicated to play a major part in the metabolism of acetaldehyde. Therefore ALDH-I deficiency has been assumed to give rise to aversive effects to alcohol which are caused by a high blood acetaldehyde concentration. Recently Ethanol Patch Test(EPT) was suggested as a screening test to dectect ALDH-I deficiency. The mechanism of skin erythema of EPT is presumed to involve vasodilatatlon due to an accumulation of acetaldehyde in the skin. The lack of ALDH-I in the skin may be responsible for the delayed metabolism of acetaldehyde. This study was designed to evaluate the relationship between time of disappearance of skin erythema in EPT and aversive effects to alcohol in 38 alcoholic patients and 42 control subject. The results was as follow : 1) The difference of total lenght of times of disappearance of skin erythema in EPT between two groups was significant. 2)When a patch area showed erythema 10 minutes after removal, it was judged to be ALDH-I dificiency. 10.52% of alcoholic patients and 32.55% of control subjects were catergorized as ALDH-I deficient. 3) When the results of EPT were compared according to response degrees on each item in two groups, significant items were No. 1, 2, 14. 4) When the results of EPT were compared according to total scores on each dimension in two groups, physiological aversive and psychological aversive dimensions were significantly correlated only in control subjects.

Phenyl isocyanaide(PIC) and its derivatives were prepared from the corresponding anilines by the Ugi's method and were identified by the melting point and spectral data. The rate constants for the hydrolysis of PIC and its derivatives (p-Cl, p-Br, m-Cl, p-NO_2) were determined by ultraviolet spectrophotometry at various pH and a following general rate equation which can be applied over a wide pH range were derived. K_t=K_10+K_OH[OH^-] On the bases of this rate equation, general base and substituent effect, identification of final product, and Hammett's plots, plausible mechanisms for the hydrolysis of phenyl isocyanides were proposed.

The dynamics of water quality and phytoplankton population had examined by monthly sampling from the upper to the lower part of watergate in an artificial Shihwa Reservoir in which situated near newly cities and industrial complex on the west coast of Korea from January 1997 to December 1998. Among environmental factors, yearly average concentration of chl-a, TN and TP seemed to eutrophic or hypertrophic conditions that ranged 146.4∼245.8㎍/ℓ , 1.6∼2.7㎎ N/ℓ, 258∼448㎍ P/ℓ , 26.9∼80.7 ㎍/ℓ, 1.0∼2.4 ㎎ N/ℓ and 74∼239㎍ P/ℓ respectively. Water quality was extremely deteriorated to consistently accumulation into inner reservoir by load of pollutants from autochthonous and allochthonous until early July 1997 after embankment. Water pollution of Shihwa Reservoir was remarkble on the biological condition with largely persistent bloom of phytoplankton and increase rate of standing crops was 2.4/yr. The development trend of phytoplankton in water ecosystem were closely related to increse and decrease of physico-chemical factors and those scale seemed to control by nutrient contents. Inflow of seawater into reservoir to object of repair of water quality began on July 1997. This action was caused to variable of algal flora as well as improvement of water quality. As to see dominant species, composition of those composed to mostly freshwater algae before inflow of seawater such as Selenastrum capricornutum of green algae, Cyclotella atomus, C meneghiniana of diatom and Microcystis spp. of blue-green algae and the other hand brackish algae were dominated after inflow of seawater such as Chaetoceros dicipiens, Skeletonema costatum of diatom, Dinophysis acuminata, Gymnodinium mikimotoi, G. sanguineum, Gyrodinium spirale, Prorocentrum minimum of dinoflagellate and Eutreptiella gymnastics of euglenoid. Moreover, small flagellates including Chroomonas spp. of cryptomonad were abundant throughout the year. The cause of water deterioration during fill of the freshwater were complexly supported with extra and intra parameters. The variation pattern of phytoplankton were related to water temperature and salinity by inflow of seawater based to plentiful nutrients. The dynamics of phytoplankton were assessed to ecosystem that clearly condition of dominant by unique or a few algal species seasonally.

In order to evaluate the efficacy and safety of risperidone, 10 patients with chronic schizophrenia were examined for 8 weeks in a silgle-open study. After the wash-out period of 1 week, risperidone was administered. Efficacy was evaluated by means of Positive and Negative syndrome Scale for Schizophernia(PANSS) and Clinical Global Impression(CGI). Safety assessment included the Extrapyramidal Symptom Rating Scale(ESRS), vital signs, body weight, ECG, and laboratory tests. The results were as follows 1) On the PANSS total score, there was significant improvement of total score after 1 week (P<.05) of administratiom. 2) On the PANSS positive and negative subscal, there were significant improvement of posotive and negative scores after 2 weeks (P<.05) of administration. 3) On the PANSS general psychopatholgy subscals, there were significant improvement of general psychopathologyscores after 1 week (P<.05) of administratiom. 4) On the CGI, there was significant decreasement of clinical impression of severity of schizophrenia score after 2 week (P<.05) of administration. 5) A statistically significant increase in body weight (P<.05) was observed after 8 weeks of administration. 6) EPS reached the peak at the end of the 1st week of administration of risperidone (11.8± 24.25) but they were easily relieved by addition of benztropine and clonazepam. There was not significant change in laboratory tests, vital sign, ECG after 8 weeks of administration. These results suggest that Risperidone is an effective antipsychotics and clinically safe except for increased body weight in chronic schizophrenia.

본 논문은 일단은 고정되고 타단은 첨단 질량을 가지며, 이질 재료에 부분적으로 묻혀 있는 선형 원뿔대를 베르누이-오일러 빔으로 모델링하여 선형 원뿔대의 지배방정식을 유도하여 주파수 방정식 및 해를 구하였으며, 선형 원뿔대의 제반 무차원 변수에 대한 수치해석을 통하여 원뿔대의 진동특성 등을 분석, 고찰하였다. A linearly tapered column immersed partially in other material is considered and is modelled as a linearly tapered Bernoulli-Euler beam fixed at the bottom with a concentrated mass at the top. Its governing equations is derived and its free vibration analysis is performed for various boundary conditions. And the rotatory inertia of the eccentric lumped tip mass is considered. The problem of determining the natural frequencies leads to a eighth order determinant. The solutions of the frequency equations are obtained numerically. The non-dimensional frequency parameters are given in tabular form and the influence of non-dimensional parameters on natural frequency is discussed for various conditions.
