To investigate psychopathoIogy and executive functions of attention deficit hyperactivity disorder (ADHD) children according to intelligence level, this study included 197 ADHD children who visited the outpatient department of neuropsychiatry of YeungNam University Medical Center, from July 2000 to June 2002. The children were divided into groups based on their intelligence levels. They were compared by the Personality Inventory for Children (PIC), Conncers' Continuous Performence Test (CPT), and Wisconsin Card Sorting Test (WCST). There were significant differences in PIC, on the subscales of verbal development, socialization and autism. In the CPT, there was no significant difference. In the WCST, there were significant differences in the total number of errors, the number of perseverative errors, the number of completed categories and the number of trials needed to complete the first category. Considering these results, the intelligence level of ADHD children is related to their disabilities and behavioral symptoms.Executive functions such as abstract thinking, categorization, working memory and flexibility had significant relationship to the intelligence levels of ADHD children. Therefore, the intelligence level of children with ADHD influences the higher executive functions of regulating attention and information processing rather than attentional functions and capacity alone.

This study is to investigate the influence of the manufacturing company and fineness of cement on bleeding of concrete. According to the results, as fineness of comment increases, slump and air content of fresh concrete decrease, and setting time is shortened. The amount of bleeding abates with an increase of fineness, and it is confirmed that bleeding does not occur especially in the case of B8000. it is confirmed that bleeding does not occur. Bleeding speed is higher in the case of OPC A than in the case OPC B, and grows low with an increase of fineness. It also becomes highest at about 60 minutes, and shows slow tendency in W/C of 45% in comparison with W/C of 50%. And It is confirmed that relativity between fineness of cement and the final amount of bleeding is very favorable. As the properties of hardened concrete, compressive strength do not make much difference between OPC A and B is little, and increases with an increase of fineness.

Malignant histiocytosis, originally described in 1939 as histiocytic medullary reticulosis by Scott and Robb-Smith, is a rare histiocytic proliferative disorder that often shows an acute onset and used to progress to death within a few months. This disorder characterized clinically by fever, generalized weakness, lymphadenopathy and hepatosplenomegaly, and shows a variable range of pancytopenia. Extranodal involvement is common, with an incidence ranging from 50% to as high as 90%, skin involves8ment was noted in 10% to 15%. Typical skin lesions were mainly founded in extremity. i.e. erythematous papule and nodule occasionally become to necrosis and ulceration. We experienced one case of malignant histiocytosis in a 46-years-old female. The major clinical findings are fever, malaise, hepatosplenomegaly and erythematous skin lesion. In the laboratory study, pancytopenia is noted on the peripheral blood. And also aggregation of many atypical histiocytes were shown on skin and bone marrow biopsy. So we reported one related case with malignant histiocytosis as well as reviewing literature .

Background: In recent years, there has been increasing interest in the use of capnometry, the noninvasive, continuous measurement of end-tidal carbon dioxide(ETCO2) in expired air during CPR. The purpose of this study is to determine the significance of ETCO2 monitoring according to immediate cause of arrest during CPR as a prognostic indicator of successful resuscitation and survival. Methods: A prospective, clinical study was performed from May 1997 to December 2000 at the Department of Emergency Medicine, Ewha Womans University Mokdong Hospital. The study included 220 patients(231cases). All patients were immediately connected to a mainstream capnometer sensor between the tube and the bag after endotracheal intubation using an infrared capnometer. Results: The 107 patients(46.3%) with return of spontaneous circulation(ROSC) had higher maximal ETCO2 during CPR than the 113 patients without ROSC(31.0±19.4 vs 11.7±9.4 mmHg, P=0.000). The ETCO2 was not significantly different in relation to age, initial rhythm, and survival time after ROSC, but there was a significant difference in the immediate cause of arrest in the ROSC group(respiratory arrest: 40.2±23.5 mmHg, P=0.000). In case of cardiac arrest due to trauma, maximal ETCO2 was not significant in the ROSC group compared with the non-ROSC group(18.2±16.6 vs 10.8±7.5 mmHg, P=0.208). When maximal ETCO2 was less than 10 mmHg, we observed a sensitivity of 94.4% and a specificity of 39.5% in predicting ROSC. There were 6 patients with ROSC even though the maximal ETCO2 was less than 10 mmHg. Conclusion: Continuous ETCO2 monitoring during CPR may be noninvasive and valuable predictor of successful resuscitation and survival from cardiac arrest. However, ETCO2 should not be used as a single indicator for either cardiac arrest due to trauma or withdrawal of CPR.

Effects of (±)-camphor on liver cytochrome P450 enzymes were investigated in male ICR mice. Mice were treated intraperitoneally with 0, 200, 400 and 800 mg/kg of (±) -camphor in corn oil for 3 consecutive days. Twenty four hr after the final treatment, the animals were subjected to necropsy. The activities of serum aspartate aminotransferase and serum alanine aminotransferase were slightly changed by the treatment with (±)-camphor at the doses used. Administration o(±)-camphor to mice significantly induced the hepatic activities of pentoxyresorufin O-depentylase and benzyloxyresorufin O-debenzylase and weakly induced ethoxyresorufin O-deethylase in dose-dependent manners. The present results suggested that (±)-camphor might act as a relatively specific inducer of hepatic cytochrome P450 213 in male ICR mice.

To help the guidance of treatment method, prevention of halitosis, and oral hygiene management for halitosis patient or non-halitosis group for investigating the status in accordance with awareness of halitosis to improve the oral health for college students, the survey including ques- tionnaire was performed for 331 persons of students who is studying in the Gimcheon college located in the northern province of Kyeongsang-Do. As a conclusion, the following data are obtained. 1. For the question of "I am acknowledging the halitosis", the replying person were 123 persons (37.2%), including men-69 persons(20.8%), women-54 persons(16.3%), So, in case of the ratio of acknowledging the halitosis, men was higher than women. On the contrary, for the question of "I do not acknowledging the halitosis", men-68 persons (20.5%), women-140 persons(42.3%), So, in case of the ratio of non-ackowledging the halitosis, men was much higher than women. 2. For the question of "When did you acknowledge the halitosis at most in the whole day?", total of 127 persons(38.4%) said "as soon as get up" out of the 183 persons (55%) who acknowledging the halitosis. The remaining replies were followed in the order of "before breakfast", "after breakfast", and "before sleeping". 3. In the status of oral hygiene, it showed that the persons who acknowledge the halitosis acts positively the frequency of toothbrushing (more than twice a day), method of toothbrushing, and brushing the tongue than the persons who do not acknowledge the halitosis. 4. In the status of smoking habits, there was no increment according to the duration of smoking, but in the status of amount of smoking, the persons who smokes less than half carton a day were 20 (6.0%), half through one carton a day were 31 (9.4%). So, it showed that the amount of smoking is affected to the cause of halitosis. 5. The ordinary prevention methods for oral hygiene according to the awareness of halitosis were investigated in the order of toothbrushing/brushing the tongue (37.3%), chewing the gum (33%), and using the rinsing liquids (12.4%).

Background and Objectives: The colorectal cancer rates 4th in the total cancer prevalence in Korea. The clinical patient demographics were considered with the incidence rate of the colon and rectal cancer. The clinicopathological factors were analyzed for the 5 year survival rate. Materials Methods: Of the 282 patients who were operated from Jan. 1, 1992 to Dec. 31, 2001 and diagnosed by pathological biopsy as colo-rectal cancer, 234 patients were followed up. The age, sex, location of the cancer, TNM stage, operation method, histopathological classification, metastatic region, complications after operation and the survival rate were investigated. Results: Of the 234 patients, male and female consisted of 120 cases (51.3%) and 114 cases (46.7%), with an average age of 61.6 years. The average follow up period was 52.3 months and the peri operative mortality was 5.6%. The site of the cancer was most frequent at the rectum with 127 cases (54.3%). The patients were classified according to the TNM stages with 38 cases of stage 1 (16.2%), 98 cases of II (41.9%), 72 cases of III (30.8%) and 26 cases of IV (11.1%). The 5 year survival rate in the age group older than 50 was 63.3 % and 73.5% in the group younger than 50. In regard to the operation type, the 5 year survival rate was 65.4% for elective operation and 65.8% for emergency operation. The 5 year survival rate for well differentiated, moderately differentiated, poorly differentiated cancer, and mucinous adenocarcinoma was 73.7%, 60.2%, 58.3%, and 92.6%, respectively. The 5 year survival rate of each of the TNM stage is 81.1%, 74.8%, 57.0%, and 11.5% for Classes I, II, III, and IV, respectively. Conclusion: The clinical factors were analyzed for the 5 year survival rate with no statistical significance for the age, sex, and location of the cancer. The TNM stage and histopathological differentiation were statistically significant. The colon cancer showed better prognosis compared to the rectal cancer.

In order to detect the safety and effect of various aqua-acupunctures from Scutellariae Radix, the modifications of boiling, filtration and dilution were employed for the manufacture of aqua-acupunctures. We injected 0.2cc of aqua-acupunctures into Joksamri(足三里) of rat, repeatedly. we compared subacute toxicity of them with saline group, distilled water(D.W.) group, acupuncture group and control group. The results were summarized as follows: 1. The groups were all healthy and alive, and there was no special abnormality in physical condition and autopsy. And there were not any toxic symptoms in repeating application of aqua-acupunctures to the rat, including changes of body weight, organ weight, haematological examination and serum biochemical test. 2. There was slight change of body weight in acupuncture group : We could see significance after 3 days (p<0.05) and after 7 days (p<0.001) in body weight loss. After 9 days, all tested groups were suppressed in body weight increment. 3. Result of organ weight: In Palking aqua-acupuncture(D-2 group), saline group and acupuncture group there were some statistical significance. Especially, acupuncture group revealed significant result in liver and spleen than aqua-acupunctures. From this result, we could suggest that the efficacy of acupuncture was preceded herbal medicine. 4. In serum biochemical test, we examined glucose(GLU), triglyceride(TG) and cholesterol(CHOL). In comparison with control group, the diluted 10 times of hwanggum aqua-acupuncture (× 10 group) was recognized significant decrease of glucose, but the diluted 100 times of Hwanggum aqua-acupuncture (× 100 group), D-2 group, saline group were confirmed significant increment. There was not any meaningful change of CHOL in all of tested group, excepting the acupuncture group was exhibited statistically significant decrease(p<0.05). In TG level all tested group except complex injection of standard compound (CPA group) and HG, there were significant value in statistically. The diluted solution was more significant decrease than Hwanggaum aqua-acupuncture(HG). The mutual relationship of components of aqua-acupuncture tended to decrease level of TG, regardless of its concentration. In acupuncture group, we gained some interesting result in meaningful decrease in TG. 5. Haematological examination showed significant increment of gramulocytes(GR) in all tested groups except Hwanggum aqua-acupuncture. And the diluted solutions of HG expressed very high increment of them(p<0.001). The GR and Mean Corpuscular Volume(MCV) of acupuncture group showed statistical significance.

This study is to investigate the influence of contents of mineral admixture on bleeding of concrete. According to the results, as W/B increases, bleeding occurs rapidly at early age regardless of replacement of mineral admixture, and when slump and air content are kept equal, the amount of bleeding decreases proportionately with an increase of replacing ratio of fly ash and blast furnace slag powder. Bleeding speed is highest at 60 minutes after placing concrete, and grow slower after 180 minutes. Bleeding speed also grows high with an increase of W/B, and is lower in the case of fly ash than in the case of blast furnace slag powder.
