This paper investigated how high school students perceive on nuclear power applying semantic network analysis. The total number of 250 high school students in 6 metropolitan areas responded to the survey. Results indicate that the word which most frequently appeared is 'Nuclear plant' (87 times) following by 'Japan' (71 times), 'Danger'(59 times), 'Fukushima' (59 times), 'Radioactivity' (56 times), 'Energy' (47 times), 'Youngkwang' (37 times), 'Electricity' (30times), 'Chernobyl' (29 times), 'Explosion' (25 times). For students in higher acceptance level of nuclear 'Radioactivity' (25 times) was most frequently showed up following by 'Fukushima' (23 times), 'Energy' (21 times), 'Japan' (21 times), Nuclear plant' (20 times), 'Danger' (17 times), 'Youngkwang' (16 times). For student in lower acceptance level of nuclear, the word of 'Nuclear plant' (40 times) most frequently appeared following by 'Japan' (31 times)', 'Danger' (29 times), 'Fukushima' (23 times), 'Radioactivity' (17 times), 'Energy' (16 times), 'Youngkwang' (16 times), 'Chernobyl' (15 times).
The author investigated the timing of land and wrist ossification events taking place in the hamate and pisiform by means of roentgenographic examination and its relation to the peak growth velocities in body height. Materials obtained included 493 sheets of X-ray films taken from 257 boys ana 236 girls aged between 7 and 17 years lived in Seoul area. The results indicate that; 1) The average ages at occurrence of initial ossification of the hook of the hamate were 12 years 3 months in boys and 10 years 1 month in girls. 2) The average ages at which advanced ossification of the hook of the hamate occurred were 13 years 7 months in boys and 11 years 11 months in girls. 3) Initial ossification of the pisiform appeared at 13 years 0 month in boys and 10 years 2 months in girls. 4) All three ossification events in hand and wrist, and peak growth velocity in body height occurred earlier in girls than in boys. 5) Initial ossification in the hook of the hamate and pisiform preceded or coincided with peak growth in body height in most boys and girls, on the other hand, advanced ossification in the hook of the hamate occurred around peak growth in body height but in girls did it after peak growth in body height. 6) It would appear that initial ossification in the hook of the hamate or in the pisiform, both for boys and girls, provides a better indication of approaching peak adolescent growth in body height. 7) Advanced ossification in the hook of the tamale would indicate that the period of cercumpuberal peak growth had teen entered or finished.
The purpose of this study focused on the distribution of crimes in Cheongju City. This study emphasized the characteristics of place and spatial pattern of crime in Central Business District(CBD). The crime core areas were delineated and explained through land-use based on fieldwork and GIS analysis For this aim. the police crime data of Cheongju Dongbu(east). Seobu(west) for 1998 were collected In which 3.909 indictable or similar offenses were reported. In this study, Included climes are murder. rape, robbery. arson, theft, burglary, assault and vandalism. Because theme crimes are related with site-specific crime. As a result. land-use patterns are often related to specific type of offenses. The climes in Cheongju City were concentrated in the CBD Most crimes were assaults and thefts Crime areas can be classified by the age of the offender Around Chungang and Pungmul Market in the CBD. the offender's ages were 30-50 dominantly Assaults and thefts were concentrated in Songan-gil(street). which is a place teen-ages and youngsters meet frequently The result of the buffering analysis with roads, explained 40% of crime within a 30m buffer area( including both sides) of a principal road The rest of the climes mainly occurred in the vicinity of narrow streets and alleys.
66 patients with temporomandibular disorders were selected for experimental group, and 45 normal subjects who were Dental students were selected for control group. Average age of experimental group was 30.5 years, Male to Female ratio was 2 : 3, and their age distribution were teen-ages to seventh decades. Transcranial radiography (TR) with Denar Accurad 100 was used for each group to get the values of width in joint spaces and to investigate the bony changes of articular surfaces and relative condylar position to articular fossa. In addition to TR, clinical interview and routine charting about amount of mandibular movements and occlusal variations were carried out in experimental group. The obtained results were as follows : 1. The mean values of joint space with in control group were 2.15mm to anterior, 2.98mm to superior and 2.29mm to posterior and the value of relative condylar position to the deepest portion of articular fossa was 0.21mm to anterior. In experimental group, those values were 2.01mm, 2.14mm 2.22mm and 0.12mm to posterior in sequence, respectively. Joint spaces in experimental group, therefore, were inclined to decreased, and relative condylar position was inclined to retrude. Joint space in control group showed symmetric condylar position, but in experimental group showed asymmetry. 2. Non-affected joints with no bony changes in experimental group showed the narrowest joint spaces which were thought to manifest the abnormal stress to non-affected side to dysfunctional state of contralateral affected joints. 3. Amount of mandibular movements in experimental group were within normal values in lateral movements and in protrusive movement but in opening movement with or without passive stretch, those were lower than normal values. Frequency of occlusal variation, for example, protrusive posterior contacts, open bite, median line shift to lateral side were inclined to increase with bony changes and with crepitus.
The purpose of this investigation was to analyze the color of natural teeth by means of the OFC-1001 DP colorimeter which could measure in Adams Coordinate System (L,a,b system). The subjects were the 164 persons (82 men and 82 women) ranged from the teen to the sixtieth who had come to infirmary of dental college, Chosun University. The colors of incisal third, middle third and cervical third of maxillary right incisor, maxillary right canine and maxillary right second premolar were examined after the teeth were cleaned, polished and dried. The data were analyzed statistically by means of SPSS (Statistical Package For the Social Science). The results were as follows. 1. The means of L(lightness), a (red chromaticity), b (yellow chromaticity) of all teeth were measured (Table 2,3,4). 2. The color of teeth was yellowish-gray or bluish-gray. 3. The L value and b value of the cervical third was greater than those of the incisal and middle third. 4. The L value of maxillary 2nd premolar was greater than those of maxillary incisor md maxillay canine. 5. The a & b values of maxillary canine were greater than those of maxillary incisor and maxillary 2nd premolar. 6. The average values of L,a,b of teeth between male and female were not significant. 7. The L values of teeth were decreasing and the b values of teeth were increasing as the age was increased, but there was no corelation between the a values and aging.
The purpose of this study was to identify the effects of emotional connection with parents, social support, and isolation on unmarried mothers' child-rearing efficacy. The subjects of this study were 194 unmarried mothers. Data were analyzed by frequency, percentage, Cronbach's ${\alpha}$, and Pearson's correlation using the SPSS 12.0 program. The test of the theoretical model was performed with an analysis of the correlational matrix in the AMOS 7.0 package for path analysis. The results of this study were as follows: First, the number of adult unmarried mothers was higher than that of teen mothers. Most unmarried mothers had a in low monthly income-, were unemployed, and received economic assistance from the government or social welfare institutions as a major source of their income. Their decision to have a child were for the following reason: the desire to have a child, fear of having an abortion, belief that abortion is a crime, and uncertainty about which decision to make, etc. Second, the women's emotional connection with their parents had a direct effect on social support. Social support had a direct effect on isolation:,- however, it did not have a direct effect on parenting efficacy. Third, the women's emotional connection with their parents had a direct effect on isolation. Isolation had a direct effect on parenting efficacy. Fourth, social support mediated by the women's emotional connection with their parents had an indirect effect on isolation and child-rearing efficacy. Isolation mediated the women's emotional connection with their parents and had an indirect effect on child-rearing efficacy.

Objects:The authors devebped a behavioral modification program for oveweight outpatients with schi-zophrenia and bipolar disorder will had teen treated with atypical antipsychotics, and evaluated the applicability of this program to outpatients Methods:Two men and nine women who had been treated with atypical antipsychotics and will had gained at least 5 percent of their pre-treatment body weight for 10 weeks, attended a behavioral modification program. The patients' weight, body mass index and the diet-activity scale were assessed and were compared with those of a matched comparison group will dd not attend the behavioral modification program Results:The body weight of patients who attended the behavioral modification program reduced with statistical significance, The treatment group showed significant improvement in diet-related items but not in activity-related items of the diet-activity scale Conclusions:This study suggested the applicability of a eehavioral mcdification program on weight reduction to overweight patients taking atypical antipsychotics for the frrst time in Korea Additional large scale studies are needed to validate the effectiveness of this program.
With a view to searching after a new antihypertensive or hypotensive agents in the botanical crude plants, authors intended to reevaluate several natural products caltivated in Korea. This experiment was undertaken to compare pharmacogical actions of Machilus thunbergii Siebold et Zuccarini with those of Magnolia obovata Thunberg in anesthetized rats and in normal mice. Machilus thunbergii Sieb. et Zucc., a tree belonging to the Lauraceae family, is caltivated at Ull-ung Do, and their cortecies have been used as folk medicine mingled with those of Magnolia obovata Thunberg. These two cortecies have teen also applied in chinese medicine, it was advocated that these cortecies exerted good therapeutic effects on gastritis, convulsive abdominal pain, nausea, vomiting and urinary tract disorders. Therefore, we intended to determine the pharmacological action of two palnt of different family each other, especially their effects on blood pressure and heart rate, and also their mechanism of action were observed. We studied their action with extracts of hexane(MTHE), ether(MTEE), methanol(MTME) and water(MTWE) from Machilus thunhergii Sieb. et Zucc., and also fractionations of methanol(MOME), chloroform(MOCE) and water(MOWE) from Mapolia obovata Thunberg. The results of this experiment were as follows; 1) MTME, when intravenously administered to rats, elicited the significant hypotensive responses dependent on the administered dosage. 2) MOWE was also exhibited the hypotensive effect dependent on the treated dose. 3) Depressor effect of MTME was blocked by pretreatment with hexamethonium. 4) The hypotensive response of MOWE was blocked by pretreatment with hexamethonium or hrdralazine. 5) HTME and MOWE were also observed the anticonvulsive effect and sedative effect. These results suggested that MTME may induce the hypotensive response via central sympathetic effect, but the site of action in brain are not clarified, and the hypotensive effect of MOWE may be due to dual mechanism of central sympathetic action and direct vasodilation of blood vessel.
Higenamine ($Ca_{26}H_{17}No_3$. HCI, d1-1- (4-hydroxybenzyl) -6,7-dihydroxy-1,2,3,4-tetrahydroiso-quinoline hydrochloride), which has recently teen isolated from the Aconite root, was known to the cardiotonic component of the Aconite root. The positive inotropic effect of Higenamine was observed in the isolated electrically driven left atrium from rabbits with respect to the influences of extracellular calcium and of calcium antagonists, e.g. $La^{+++}$ and verapamil. A synergistic relation in the positive inotropic effect could be demonstrated between Higenamine and extra cellular calcium. The inotropic potency of $10^{-7}\;g/ml$ Higenamine was equivalant to that of 0.058 mM of calcium in the medium. In the preparation, of which contractility had been reduced by the treatment of $La^{+++}(10^{-5}-10^{-4}M)$ and verapamil$(2{\times}10^{-7}-10^{-6}M)$, Higenamine was able to restore the contractility. These results indicated that one of the possible mechanism of positive inotropism of Higenamine was to accelerate the influx of calcium from the extracellular space through the sarcolemma.
The behavioral pattern of an animal is influenced by endogenous and endogenous stimuli such as humoral secretion, neurohumoral transmitters, drugs, light and environmental change. It has teen known that adenosine is a normal constituent of brain, and has sedative or hypnotic effects and anticonvulsant effects, inhibiting the spontaneous firing of cells in the brain via membrane adenosine receptors. Recent studies suggest that the excitatory responses to xanthines in the CNS might be related to the competitive antagonism of xanthines to adenosine. This study was undertaken to Investigate the effects of adenosine and the CNS stimulants such as picrotoxin, strychnine and caffeine on the spontaneous activity of mire, and to examine the influence of adenosine on the seizures induced by large doses of CNS stimulants. Subjects were $20{\sim}30\;g$ adult mice, and the spontaneous activity was measured using the Selective Activity Meter after intraperitoneal injection of adenosine (10 mg/kg), caffeine (100 mg/kg), strychnine(0.2 mg/kg) or picrotoxin(0.5 mg/kg) with or without adenosine pretreatment. The seizures were induced with caffeine(200, 250 and 300 mg/kg), strychnine(1.25 and 1.5 mg/kg) or picrotoxin(10 and 15 mg/kg). The results are summarized as follows : 1) The spontaneous activity in mite was significantly inhibited between 10 and 20 minutes after adenosine treatment. 2) Caffeine and picrotoxin increased the motor activity significantly while strychnine had no effect on the activity. 3) The ambulatory activity in the caffeine, strychnine and picrotoxin treated groups was significantly inhibited by adenosine pretreatment. 4) The seizures were observed with caffeine(200, 250 and 300 m9/kg), strychnine(1.25 and 1.5 mg/kg) or picrotoxin(10 and 15 mg/kg). The caffeine induced seizures were inhibited by adenosine pretreatment, but the strychnine or picrotoxin induced seizures were not affected.
