This study was conducted to investigate and analyze the dental patients' awareness and understanding about TMDs. Among the total number of 243 patients who had visited the department of dentistry of Busan Paik Hospital, Inje University or Hanvit dental hospital in Ulsan metropolitan city and participated in the survey, 195 patients who filled in all parts of the questionnaire were selected as the subjects. The results were as follows. 1. The subjects who were aware of the term, "TMDs" were 17.4%. The group with total education period of 12 years and over was significantly more aware of "TMD"(82.4%, p<0.01) than the other group. The subjects who were aware of the term, "jaw joint disease" were 81.0%. 30 to 49 age group(45.6%, p<0.05) and the group with total education period of 12 years and over(60.1%, p<0.01) were significantly more aware of "jaw joint disease" than other groups. 2. More than half of the subjects chose "overuse of the jaws" as the concept of jaw joint disease(50.6%). 3. TV, radio(41.4%) was the most frequent source of awareness about jaw joint disease followed by family and friends(20.2%), hospitals and health professionals(18.2%), internet(15.7%) and newspapers, magazines(4.5%). Among the respondents who were aware of jaw joint disease through TV, radio, 30 to 49 age group showed significantly higher percentage(52.4%, p<0.05) than other age groups. Among the respondents who were aware of jaw joint disease through internet, 18 to 29 age group showed significantly higher percentage(61.3%, p<0.01) than other age groups. Among the respondents who were aware of jaw joint disease from hospitals and health professionals, the group with total education period of 12 years and over showed significantly higher percentage(75.0%, p<0.05) than the other group. 4. Noise during mouth opening and closing(26.9%), mouth opening difficulty(25.1%) and jaw pain(13.7%) were the most frequently responded sign and symptoms of jaw joint disease. For the causes of jaw joint disease, enjoying hard food chewing(19.5%), occlusal discrepancy(19.0%) and chewing with one side only(18.5%) were responded in sequence. TMJ surgery(28%) was the most frequently responded treatment method for jaw joint disease, followed by occlusal appliance therapy(23.9%) and physical therapy(14.6%). For preventive method of jaw joint disease, avoid eating hard food(21.1%), avoid opening mouth wide(17.0%) and simultaneous using of molar of both side when chewing food(15.4%) were chosen frequently.

Anti-inflammatory effects of sulfur-fed duck extract on colitis induced by 2.5% dextran sulfate sodium (DSS) were examined in male Balb/c mice. Animals were divided into eight groups: normal (0.1 mL of PBS without 2.5% DSS), control (0.1 mL of PBS with 2.5% DSS), SD-H (3 mL/kg of high sulfur-fed duck extract), SD-L (1 mL/kg of low sulfur-fed duck extract), GD-H (3 mL/kg of high general duck extract), GD-L (1 mL/kg of low general duck extract), GC-H (3 mL/kg of high general chicken extract), and GC-L (1 mL/kg of low general chicken extract). Mice were fed PBS or six different doses of extracts (sulfur-fed duck, general duck, and chicken), once daily for 14 days. Colitis was induced from day 7 to 14 via the administration of 2.5% DSS in drinking water. The colon length was significantly shortened in mice compared to the control group. The administration of SD-H, SD-L, and GD-L increased colon length and decreased histological colon injury from DSS-induced colitis. However, chicken extracts did not recover any clinical sign of the colitis. SD-L significantly suppressed not only the concentrations of IL-$1{\beta}$, IL-6, TNF-${\alpha}$, IL-17A, and IL-12 in serum but also the mRNA expressions of IL-6, TNF-${\alpha}$, iNOS and COX-2 in DSS-treated colon tissues (P<0.05). The administration of SD-H suppressed the concentrations of IL-6 in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. Administration of GD-L suppressed the concentrations of IL-6, TNF-${\alpha}$, and IL-17A in serum and the mRNA expressions of IL-6, iNOS, and COX-2 in colon tissues. The inhibitory effects of sulfur-fed duck extracts were effective at a dose of 1 mL/kg. Our results indicate that sulfur-fed duck extracts may possess anti-inflammatory effects on DSS-induced colitis mice.

In vivo $^1$H magnetic resonance spectroscopy (MRS) at 4.7 T was applied to investigate the cerebral metabolite changes of mice brain before and after experimental brain trauma. In vivo $^1$H MR spectra were acquired from a voxel covering right parietal cortex in normal brain, used as control subjects. After experimental brain trauma using the fluid percussion injury (FPI) method, $^1$H MR spectra were acquired from the same lesion three days after trauma. Metabolite ratios of the injured lesion were compared to those of controls. After trauma, N-acetylaspartate (NAA)/creatine (Cr) ratio, as a neuronal marker was decreased significantly versus controls, indicating neuronal loss. The ratio of NAA/Cr in traumatic brain contusion was 0.90$\pm$0.11, while that in normal control subjects was 1.13$\pm$0.12 (P=0.001). Choline (Cho)/Cr ratio had a tendency to rise in experimental brain contusion (P=0.02). Cho/Cr ratio after trauma was 0.91$\pm$0.17 while that before traumas was 0.76$\pm$0.15. Cho/Cr ratio was increased and this might indicate a inflammatory activity. However, no significant difference of [(glutamate＋glutamine) (Glx)]/Cr was established between experimental traumatic brain injury models and normal controls. Lactate (Lac)/Cr ratio was appeared as a sign of shifted posttraumatic energy metabolism and increased versus controls. These findings strongly suggest that in vivo $^1$H MRS may be a useful modality for clinical evaluation of traumatic contusion and could aid in better understanding the neuropathologic process of traumatic contusion induced by FPI. In the present study, in vivo $^1$H MRS was proved to be a useful non-invasive method for in vivo diagnosis and monitoring of posttraumatic metabolism in models of brain contusion.

Purpose : Non-accidental intracranial hemorrhage in children is not low in incidence and results in high mortality and serious sequelae. So, the authors have researched the distribution of sex and age, causes, symptoms and signs, hemorrhagic types, mortality rate and sequelae of the patients hospitalized with non-accidental intracranial hemorrhage at Hallym University Sacred Heart Hospital. Methods : The medical records of twenty patients, aged 15 or younger, and excluding neonatal patients, were analyzed retrospectively. The patients in this study were admitted with non-accidental intracranial hemorrhage from January 1999 to June 2002. Results : Of the twenty cases, the ratio of male to female was 1 : 0.8. The patients aged one or less and between 11 and 15 were discovered to be the most frequent cases. Shaken baby syndrome and arteriovenous malformation were found to be the most frequent causes. Seizure was most frequently found to be a symptom and a sign. Hemorrhagic type was classified into subdural hemorrhage eight, intracerebral hemorrhage five. There were three mortal cases. Twelve surviving patients, excluding five not-followed ones, were reclassified into six cases of complete recovery and six of sequalae. Conclusion : Non-accidental intracranial hemorrhage in children is not low in incidence, with a high mortality rate and a high incidence of serious sequelae after survival. Consequently, early diagnosis and appropriate treatment are required. In addition, appropriate rehabilitation after treatment is needed because the high survival rate due to advanced medical treatment results in an increasing number of neurologic sequelae.

Purpose: The purpose of this study was to evaluate the clinical and abdominal ultrasonogra- phic(US) features of spontaneously reduced transient small bowel intussusception in chlidren. Methods: We retrospectively reviewed the clinical and US findings of 98 children with intussusception who were admitted to the Pediatric Department of Ulsan Dong-Kang General Hospital from Mar. 1999 to Feb. 2000. Results: 1) Among 98 cases, there were 12 cases (12.3%) of transient small bowel intussusception(TSBI) and 86 cases (87.7%) of classic intussusception (CI). 2) The peak incidence of age in TSBI was over 3 years, which was older than that in CI. With regard to sex distribution, male predominated in both type. 3) Clinical symptoms and signs including cyclic irritability, vomiting, bloody stool, and abdominal mass in TSBI group were less common than those in CI group (41.7%, 33.4%, 0.0%, 0.0% vs 91.9%, 59.3%, 41.9%, 26.7%, respectively) but persistent abdominal pain was more common in TSBI group than in CI group (58.5% vs 11.2%). 4) The size of total target sign and surrounding peripheral hypoechoic rim of TSBI group on US were smaller than those of CI group ($11.95{\pm}2.61$ mm, $2.08{\pm}1.15$ mm vs $26.91{\pm}5.98$ mm, $7.86{\pm}2.77$ mm, respectively). 5) Concomittant illness was found more frequently in TSBI group than in CI group (66.7% vs 26.7%). 6) All case of TSBI group were reduced spontaneouly, which were confirmed by US, but none of CI group. Conclusion: Transient small bowel intussusception is probably more common than generally thought and its clinical and US findings is quite different from classical obstructing intussus-ception. Because all of our cases resulted in spontaneous reduction, we recommend careful observation and repeat examination rather than an immediate operation in transient small bowel intussusception.

This study was done to investigate how importantly midwives thought of Lamaze Method of Childbirth, how satisfactorily they performed their Lamaze Method of Childbirth and what inhibited their activities from being performed if not done satisfactorily. The subjects of this study were 76midwives at midwifery in Pusan, Deagu, Kyungnam and Kyungbok. Data were collected by using questionaire from Sep. 1 to Sep.30, 1991. The measurement tools was maded by the researcher based on Kim's scale for prenatal nursing activities. The statistical analysis was done with based statistical values likes frequencies, means, standard deviations and advanced methods such as Pearson's correlation coefficient, 1-test, F-test, F-test by using SPSS package program. The results of this study can be summarized as follows ; 1. The results of Investigating perception according to importance degree and performance degree of Lamaze Method of Childbring showed that midwives were slightly below both perception according to importance(2.17) and performance(2.16) of Lamaze Method of Childbirth 2. Inhibiting factors of Lamaze Method of Childbirth were abscence of husband(3.08), lack of teaching room(2.71), and lack of books or literature of Lamaze Method (2.58). 3. There appears to be a positive relation between perception according to importance degree and performance degree of Lamaze Method of Childbirth (r=0.69, P<0.01). There appears to be a negative relation between perception according to importance degree and inhibit factors of performance (r=-0.38, P<0.01). There appears to be a negative relation between performance and inhibit factors of performance (r=-0.22. P<0.01). 4. The item of highest perception defree in prenatal education is 1st, Consultation about sexual life (2.53), End, illustration of the importance of a bath and perinal cleanliness and Avoidance of excessive respiration method and also its comfortable application during uterine contractility(2.45). The item of lowest perception degree is about pregnant symptom sign and predicted date of birth (E.D.C.). On the other hand, The item of highest performance degree is education about nurtrition during pregnacy. 2nd, Illustration of the Importance of a bath and perineal cleanness(2.45). The lowest one is leaching the pregnant woman and her family about the role of husband and her family and also teaching the couple to learn exercise and respiration method (1.84). Though importance perception degree and performance degree is low. Midwives who wert subject in this research shoves that they perform general items concerning prenatal education well. 5. In the relationship between perception according to importance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in mean number of visiting pregnacies for 1 month. 6. In the relationship between performance degree of Lamaze Method of Childbirth and the general characteristics of subjects, the differences in age, marriage, and mean number of visiting pregnancies for 1 month. With the above information we see the importance of midwife prenatal care education and high correlation between performance degree and perception degree. When Lamaze prenatal education is well performed the number of pregnant woman who have follow-up, check-ups increase. Therefore in this research we can validity that there is a relation between Lamaze prenatal education and patient follow-up. This research showes in a situation where if one does not maximally perform a prenatal education there is a possibility that the popular use of midwife activities may encounter obstacles so the education to save new knowledge and training for prenatal education is needed as a function of Lamaze prenatal education, when a special Lamaze education is well performed for the pregnant woman, who follows-up at amidwife clinic. With the above conclusion we can suggest : 1. Continued research which minimized obstacles to Lamaze prenatal education is needed. 2. The official method of midwives is necessary.

This study reviews the concept and protection system for the geographical Indication(GI) to support the Korea-EU FTA. A geographical indication(GI) is a name or sign used on certain products or which corresponds to a specific geographical indication or origin (eg. a town, region, or country). The use of a GI may act as a certification that the product possesses certain qualities, or enjoys a certain reputation, due to its geographical origin. In the WTO Agreement on Trade-Related Aspects of Intellectual property Rights("TRIPS"). There are, in effect, two basic obligations from Article 22 to article 23 on WTO member governments relating to GIs in the TRIPS agreement. Geographical Indications have long been associated with Europe as an entity, where there is a tradition of associating certain food products with particular regions, Under European Union Law, the protected designation of origin system which came into effect in 1992 and 2003 regulates the following geographical indications: Protected designation of origin(PDO) and protected geographical indication(PGI) and Traditional Specialty Guaranteed(TSG). They have 5,000 articles for GI. We have the GI system and 40 articles rotating to registration by the law for quality management of production in agriculture. Cinclusinally, geographical indications could potentially serve as tools to helf holders of trade benefit more equitable through the mutual Acceptance for Korea-EU FTA.

Through immersing barley seeds (variety; Suwon No. 6) into different dilution of carrier-free P-32 original solution (Total activity; 90mc, To; 3/21) for 24 hours at room temperature, four groups of seeds (each group consists of 200 seeds) having activity levels of 1.6$\times$10-3$\mu$c 32P/grain, 2.3$\times$10-1$\mu$c 32P/grain 6.9$\times$100$\mu$c 32P/grain and 2.5$\times$101$\mu$c 32P/grain respectively, were obtained. To investigate the effects of various activity levels of P-32 absorbed upon the test plants, the seeds were germinated, transplant into the pots, and the growth was observed for three months after germination. After harvest, the inorganic contents in the leaves and the stems were also analyzed. The results: 1) Until four days after the beginning of germination, the rate of germination was found the lowest at the strongest activity level of 2.5$\times$101$\mu$c/grain. At the other P-32 levels treated, it showed generally higher than the control. 2) Before transplanting the seedlings of both 1.6$\times$103$\mu$c/grain and 2.3$\times$10-1uc/grain levels showed more vigorous growth than the control, whereas at the 6.9$\times$100 uc/grain level a retarded growth was conspicuous and all of plants belonging to the highest activity level of 2.5$\times$101$\mu$c/grain were withered owing apparently to the radiation damage. 3) This trend of growth promotion was continnually observed at the low activity levels even after transplanting the seeldings to the pots. As for the plants belonging to 6.9$\times$100$\mu$c/grain level, a clear sign of gradual recovery from the damage afflicted at the earlier stage was observable, and as a result the plants showed more growth than those of control two months after transplanting. 4) The number of stems diverged was found somewhat small in the blocks treated with P-32, compared with that of control until two months after germination. At the later stage of growth there seemed no significant difference among the themselves. 5) The dry weight of leaves and stems was proved that the lower the activity, the mroe it was produced. The relative increase of dry matter in each treatment compared with the control was 2% at 6.9$\times$105$\mu$c/grain level, 9% at 2.3$\times$10-1$\mu$c/grain and 35% at 1.6$\times$10-3$\mu$c/grain respectively. 6) The inorganic contents of the leaves and stems harvested were proved that: (1) Nitrogen was highest at the lowest activity level of 2.3$\times$10-1$\mu$c/grian. (2) Phosphorus showed generally higher contents in the treated blocks than in control, with the peak being at 2.3$\times$10-1$\mu$c/grain. (2) Phosphorus showed generally higher contents in the treated blocks than in contro, with the peak being at 2.3$\times$10-1$\mu$c/grain level in the leaves and at 6.9$\times$100$\mu$c/grain in the stems. (3) These was no significant difference in potassium contents in the leaves between treatment and control, whereas in the stem the treated blocks were higher than control roughly in propotion to the activity level. (4) Calcium in the lesves was richer in treated blocks than control while in the stem no difference was seen. (5) Magnesium contents both in leaves and in stems there was no difference among treatments.

Purpose: Recognition of impending death is crucial not only for efficient communication with the caregiver of the patient, but also determination of the time to refer to a separate room. Current studies simply list the events 'that have already occurred' around 48 hours before the death. This study is to analyze the predictability of each event by comparing the time length from 'change' to death. Methods: Subjects included 160 patients who passed away in a palliative care unit in Incheon. The analysis was limited to 80 patients who had medical records for the last week of their lives. We determined 9 symptoms and 8 signs, and established the standard of 'significant change' of each event before death. Results: The most common symptom was increased sleeping (53.8%) and the most common sign was decreased blood pressure (BP) (87.5%). The mean time to death within 48 hours was 46.8% in the case of resting dyspnea, 13.6% in the ease of low oxygen saturation, and 36.9% in the case of decreased BP. The symptom(s) which had the highest positive predictive value (PV) for death within 48 hours was shown to be resting dyspnea (83%), whereas the combination of resting dyspnea and confusion/delirium (65%) had the highest negative PV. As for the most common signs before death within 48 hours, the positive PVs were more than 95%, and the negative PV was the highest when decreased BP and low oxygen saturation were combined. The difference in survival patterns between symptoms and signs was significant. Conclusion: The most reliable symptoms to predict the impending death are resting dyspnea and confusion/delirium, and decline of oxygen saturation and BP are the reliable signs to predict the event.

Purpose: We divided the children diagnosed with intususception into three different age groups and compared the clinical symptoms and treatment outcomes in order to analysis diagnosis and treatment of Intusussception. Methods: A retrospective chart review was established of 159 patients diagnosed with intussuception who had been admitted to Department of Pediatrics and General Surgery, Bundang CHA hospital from January, 2000 to May, 2004. We divided the patients into three groups, according to their age. Those who were under five months of age (group I; 21 patients), those between 5~11 months of age (group II; 61 patients), and those older than 11 months of age (group III; 77 patients). Then we compared the age, sex, seasonal distribution of occurrence, the cause, the clinical features, radiologic review, the type of intusussception, surgical methods, recurrence rate and treatment outcomes, among these three groups. Results: On comparing the clinical symptoms and signs among the three groups, the most common major clinical symptom and sign was irritabiltity in all three groups. Vomiting with irritability was statistically more common in group I (p<0.05) and bloody stool was most frequent in group III. The average time taken until a diagnosis was made after the symptom onset was, 21 hours in group I, 20 hours in group II and 22 hours in group III. Which showed no significant difference. But there was a higher rate of delayed diagnosis in group I, which took over 48 hours until the diagnosis was made (group I; 23.8%, group II; 4.9%, group III; 7.8%). Simple abdominal X-rays showed more frequent instances of intestinal obstruction in group I (p<0.05). The primary treatment done was barium enema which showed a failure rate of 52.4% in group I, 26.2% in group II and 14.3% in group III. Showing the highest failure rate in group I. Conclusion: The youngest group had vague symptoms which lead to delayed diagnosis and more frequent surgical procedures. As so, we advocate the importance of further evaluation and close observation, considering intussusception in children with symptoms of irritability and vomiting, especially in the early infant group.
