The present study attempts to find the ways to efficiently manage dental caries, one of the major causes of tooth loss, and to cope with oral diseases that deteriorate oral health. For this purpose, this study seeks to obtain fundamental data needed in planning the oral health projects. The study was conducted to the first-grade elementary school students in Hwa-Seong city, Gyeonggi-do, from April 1 - 30, 2002. The result was as follows: 1) Among a total of 2,710 subjects, 598 (274 boys and 324 girls) have more than 1 permanent tooth with a caries legion whether it was treated or not. 2) The number of permanent teeth examined is 6,029, in which girls' teeth are more (3,165) than boys' (2,864). 3) Out of a total of 6,029 teeth examined, 1,106 permanent teeth (508 boys' and 598 girls') have caries legions. 4) Out of 1,106 permanent teeth with caries legions, 170 (15.4%) were treated - 67 teeth for boys (13.2%) and 103 teeth for girls (17.2%). 5) 22.1% of the children have experienced dental caries in their permanent teeth. Among them, 20.1% are boys and 24.1% are girls. 6) The rate of the permanent teeth that once had, or now have caries legions are 21.2%, among which the rate for boy's teeth is 20.1% and that for girl's teeth is 22.1%. 7) The number of the permanent teeth that had caries legions is 0.5 for all the subjects. A boy has 0.4 and a girl has 0.5 teeth with caries legions regardless of whether it was treated or not. 8) The rate of the permanent teeth with caries legions is 86.7% for overall subjects - 88.3% for boys and 85.3% for girls. 9) The rate of treated permanent teeth is 13.3% for all the subjects - 11.7% for boys and 14.7% for girls. Based on the above result, the study draws a conclusion that in order to prevent dental caries in young students and to perform an early treatment for the dental caries that already occurred an oral health office should be installed at all the elementary schools so that elementary school students don't experience a loss of time and effort for learning and suffer nutritional imbalance or disorder. Besides, the oral health education concerning the importance of dental care should be conducted to the citizens, especially to the young people, in the community as an essential project of oral health centers in the community health offices, the public medical institutions.

Korea's overseas construction awards reached US $750 bn for more than 50 years since it first entered the market in 1966. In particular, the company won US $540 bn over 10 years from 2007, achieving 72% of the total contracts. However, in recent two years, awarded amounts have decreased by 40% each year. The most significant decline is due to the impact of international oil prices, which have plummeted since end of 2014, as oil-producing nations, which are Korea's major target countries, are struggling to cancel or postpone infrastructure orders. In order to lessen the impact of raw material price fluctuations, the recent trend is that even countries with relatively loose government financing conditions are rapidly changing their ordering methods to investment development forms such as PPP. The Korean government and companies have been already preparing for this for several years, but they are still not doing so well. The main reason is the lack of understanding about the investment development type project, especially financing methods and the aggravated fear of exposing it to various risks due to the characteristics of the development project, which takes a long time to collect the investment. In this paper, I propose a more systematic solution to financial process and risk management, which is recognized as a obstructive factor for Korean companies, in line with the recent government-led establishment of overseas infrastructure development support organizations. I would like to serve as a investment guide.

Purpose: This study aims to examine perceived safety management in teachers working for young children with disabilities, to grasp the state and problems of safety management and first-aid education at daycare center for young children with disabilities, and to provide basic materials to develop programs for safety management and first-aid education. Results: 1. For the perception items of accident possibility in daycare centers, career with more than 10 years had higher response in 'very high' and 'moderately high' than 'moderately or very low' and statistically significant difference was found(p < .05). 2. For the perception items of accident prevention in daycare centers, no teaches with at least college education thought that 'it was not possible to prevent' and most of them thought that 'it was totally possible to prevent' and statistically significant difference was found(p < .05). 3. For the performance level of safety management and first-aid items, forty and over(4.73) showed higher than age of 20-29(4.32) and 30-39 of age(4.26) and statistically significant difference was found(p < .05). 4. For the knowledge level of safety management and first aid items, the highest religion was found as Christian(16.96), followed by Catholic(15.33), Buddhism(14.91), and no religion(15.81) and statistically significant difference was found(p < .05). 5. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed safety management and first-aid education( 4,48) had higher performance score than those who did not (4.17) and statistically significant difference was found(p < .05). 6. For the items of confidence in safety management and first aid, performance level, and knowledge level, teachers who competed first-aid education(2.77) had higher confidence than those who did not(2.35) and statistically significant difference was found(p < .05). Conclusion: The results suggest that safety management and first-aid education in teachers working for daycare center for young children with disabilities was closely correlated with knowledge and performance levels. Thus, it is necessary to provide continuous safety management and first-aid education for teachers working for day care center for young children with disabilities through regular in-service training. Also further research should be conducted with all subjects and various regions who contact with young children with disabilities.

대기오염물질이면서 동시에 생체내 화학반응의 산물이기도 한 nitric oxide(NO)는 그 생체내 분포가 광범위하고 생리적 역할이 다양하여, 최근의 생명과학 분야에서 가장 크게 주목받는 몇가지 연구대상 중 하나이다. 세포에서의 NO 산생은 nitric oxide synthase (NOS)에 의해 촉매되는데, 이들은 brain form (bNOS, neuronal; nNOS, NOS I), inducible form (iNOS), 및 endothelial form(eNOS)로 구분되는데, 이중 bNOS(nNOS)와 eNOS는 inducible form에 대비되는 constitutive form(cNOS)에 해당하므로 각각 ncNOS 와 ecNOS로도 불리운다. NOS는 아미노산인 L-arginine을 산소와 결합시켜 L-citrulline으로 변환시키면서 NO를 유리하고, 이 NO는 세포내의 guanylate cyclase를 활성화하여 cyclic GMP를 생산하거나, superoxide(O2-) 및 수소이온과 차례로 결합하여 반응성이 매우 높은 수산화기(-OH)를 발생시켜 세포독작용을 유발하기도 한다. 정상상태에서 뇌혈관내피세포의 ecNOS로 부터 유리된 NO는 혈관을 확장시켜 신경세포에 대한 산소공급을 원활히 유지해 주지만, 순환장애를 일으켰을 때는 뇌조직내의 iNOS로부터 대량의 NO가 유출되어 신경세포의 손상을 가져온다. 호흡기에서는 NO가 기도평활근을 이완시키고 폐혈류를 개선하므로, 미숙아나 성인의 호흡장애시에 소량의 NO를 흡입시키면 oxygenation을 호전시킬 수 있다. 그러나 대기오염이나 흡연 등으로 대량의 NO를 흡입할 경우 치명적인 폐부종이나 methemoglobin혈종을 일으킬 수 있다. 순환계에서는 cNOS가 혈관을 확장시켜 조직의 혈류를 유지하는데 일익을 담당한다. 세균내 독소(lipopolysaccharide; LPS)나 각종 명역조절물질들이 혈관내피세포와 혈관평활근세포로 부터 과다한 NO를 유리시키면 혈압이 급격히 떨어져 순환허탈상태에 빠지게 된다. 심장에서는 관상혈관 내피세포의 eNOS가 심근의 혈류를 유지해 주지만 허혈이나 세균내독소 또는 면역조절물질 등에 의하여 심근세포나 침윤된 대식세포의 iNOS로 부터 과량의 NO가 유리되면 심근세포의 손상이 초래된다. 신장에서는 내피세포의 cNOS에 의하여 사구체여과가 조절되고 있는데, 세균내독소나 면역 조절물질 등에 의하여 사구체관막세포(mesangial cell)등의 iNOS로 부터 과량의 NO가 유리되면 신조직과 사구체의 손상을 초래한다. 위와 같이 대부분의 장기에서 ecNOS는 조직의 혈류를 유지하는 역할을 하며, iNOS는 애초 세균 등 침입자에 대한 세포독작용이 그 존재 목적이라고 풀이할 수 있겠으나 일종의 부작용으로 자체조직의 손상을 초래하게 되는 것으로 본다. 따라서 NO와 관련된 각종 병변의 치료를 위해서는 NOS의 비선택성 억제제인 arginine 유도체 보다는 iNOS에 대한 선택적 억제제인 S-methylisothiourea(SMT), aminoethylisothiourea(AETU), aminoguanidine (AMG), agmatine, L-canavanine, transforming growth factor b1(TGF-b1) 등의 사용을 검토해 보는 것이 타당할 것으로 사료된다.

This study aimed to investigate the acoustic differences that occur in diverse sections of sustained vowel phonation, which is often used in an objective speech analysis of voice disorder patients. The subjects included 17 voice disorder patients (vocal nodules) and 12 normal individuals without any voice disorder. The participants' sustained vowel phonation of /a/ was divided into onset, middle, and offset, and the jitter, shimmer, and NHR in each section were analyzed using the MDVP(Multi-Dimensional Voice Program). The Friedman test and post hoc analysis were used. In the vocal nodules group, the jitter, shimmer and NHR were significantly higher in the off section of sustained vowel phonation than in the middle section, and there were no significant differences between the beginning and middle sections. In contrast, in the group of normal individuals, there were no significant differences between any of the sections. The values of the acoustic parameters according to the section of analysis in the sustained vowel phonation are different and the vocal in the end section is significantly more unstable than that in the middle section. The results of this study will be useful for selecting the sections to be analyzed in sustained vowel phonation and interpreting the results of the analysis.

Mothers of handicapped children experience many problems and difficulties related to the child's prolonged dependency and demands for special care. Social support can be identified as stress-relieving factor, social support is considered to decrease the amount of negativeness in an individual or family. This study attempted to identify the level of burden and social support in mothers of children who are handicapped, and to determine whether social support is an effective strategy for burden relief in these mothers. The method used in the study was a correlational descriptive survey using a questionnaire. The subjects for the study were 42 mothers who have the handicapped children, between two to twelve years of age, being treated at S General Welfare House for Handicapped and S Rehabilitation Center in Seoul. The data were collected during 1 month from March 20 to April 20, 1996. The instruments used for this study was a structured questionnaire which was the Burden scale developed by Suh Mihae and Oh Kasil(1993) and the PRQ(Personal Resource Questionnaire) scale developed by Brandt & Weinert(1981). The collected data were analyzed using the SPSS computer program, yielding frequencies, percentiles, means, standard deviations, $x^{2}$-test, Pearson's correlation coefficienct, t-test and ANOVA. The results of this study are as follows ; 1)The range of age in the subjects was $29{\sim}44$ years, the range age in the handicapped children was $2{\sim}12$ years. 2) The mean score of burden, for the mothers of the handicapped children was 2.75(standard deviation was 0.47) of a possible total of 5. 3) The mean score of social support, for the mothers of the handicapped children was 4.99 (standard deviation was 0.59) of a possible total of 7. 4) There was an negative correlations hip between burden level and the social support, but there was no statistically significant correlationship between burden level and the social support(r = -.2252, p = .076) 5) In the general characteristics influencing on the burden level was significantly related with the sex(t = - 2.87, p = .007) and the degree of child's handicap level(F = 11.8680, p = .000l). In the general characteristics influencing on the social support was significantly related with the family(husband) support(F = 3.5199, p = .0240). There were significant differences in the mother's levels of burden depending upon the severity of child's handicap. In other words, the degree of mother's burden was directly proportionate to the degree of child's handicap level. There were significant differences in the mother's levels of social support depending upon the family(husband) support. In conclusion, on the basis of the results of this study, there was no statistically significant correlationship between burden level and the social support. Above results suggest that strategies for the intervention programs in diminishing the mother's burden and reinforcing the social support.

Objective : The purpose of this study was to provide evidence for the effectiveness of Sensory Integrative Intervention (SII) through a systematic review. Method : The systematic review was executed using MEDLINE/PubMed, PsycINFO, CINAHL, Cochrane Library, OTSeeker. The key words for search was "effects of sensory integration", "sensory integration therapy", and "sensory integration intervention". 11 studies were used for data analysis, and the level of evidence were level I, leve lII and level IV. The substances of review were subject (population), method (intervention type), effect of the intervention, outcome parameter, and outcome measurement. Results : 1. The subjects of SII were autism spectrum disorders (30.7%), pervasive developmental disorder (15.4%) and preterm infants (15.4%). 2. Most frequently used method was the traditional intervention of J. Ayres (36.5%). The outcome parameters of SII were behavioral outcome (40.63%), motor performance outcome (28.13%), sensory-based outcome (25.0%), and academic outcome (6.35%). 3. The effects of SII were improvement of motor performance (66.7%), sensory-based (62.5%), and behavior problems (61.5%). In most studies, however, academic skill such as writing skill was not a positive outcome parameter in terms of effectiveness of SII. Conclusions : The results implied that the sensory integrative intervention is effective on motor performance, sensory-based and behavioral change, but not on the academic skill. It is suggested that the future research need to be done to examine whether and how the effect of sensory integration intervention can be long-lasting and contribute any academic skill and activities of daily living performance.

Tongue-tie is a congenital anomaly characterized by an abnormally short lingual frenum, which may restrict tongue tip mobility, In the neonate and infant, tongue-tie was said to cause difficult breast-feeding, In the older infant, toddler and young child, poor speech has been frequently listed because movement of tongue tip is limit ed. Also as a abnormal tongue position, various orthodontic problems, later mechanical and social manifestations could be developed. Treatment options such as observation, speech therapy, frenotomy and frenectomy have been suggested. The optimal timing for the surgery has not been determined, but early intervention may be appropriate for the children with significant tongue-tie who has the significant potential to speech difficulties and later social and mechanical problems. Sedation is an effective method for incapable of cooperative and the handicapped children, necessary to early intervention. We report three cases, using oral sedation for the frenectomy in young children with severe tongue-tie. After treatments, we could find out sufficient tongue movement and improved speech ability.

Objective : To provide a foundation to develop clinical training program based on a status of sensory integration therapy in Korea identified through the study. Methods : A questionnaire has been developed that is investigating such as environment of therapy, level of knowledge of therapist, and etc. The questionnaire was distributed from June 1st,2014 June 1 to August 31st,2014. The total questionnaire result collected and analyzed are 232 responses. Results : In terms of ratio of therapist who are administrating sensory integration, occupational therapist takes biggest percentage. In most case, it is equipped enough to do treatment in terms of space and tools. Generally, therapists are performing evaluation and documentation earnestly, and willingly participating to continued education and clinical training coursework. However, it is found that some cases are implementing treatment without through evaluation and/or without professional training. Conclusion : This study propose that sensory integration therapists need to train their clinical knowledge and skills through professional training education based on the Ayres Sensory Integration (ASI) theory. Most of professional trainings are administered in capital area currently. The educational opportunities need to be extend to outside of capital region so the level of clinical competence and the quality of the therapy service can be improved.

Imipramine, a tricyclic antidepressant (TCA), is used for the treatment of non-polar depression and nocturnal enuresis in children in whom an organic pathology has been excluded, anxiety disorders, and neuropathic pain. Clinical toxicity following the treatment of TCAs, including imipramine, is well known. The anticholinergic effects initially present include a dry mouth, ileus, dilated pupils, urinary retention, and mild sinus tachycardia. The central nervous system toxicity includes delirium, agitation, restlessness, hallucinations, convulsions, and CNS depression or coma. However, the most life-threatening toxicity remains the development of cardiac dysrhythmias. Conduction delays such as QRS and corrected QT prolongation, wide QRS complex tachycardia, and the Brugada electrocardiographic pattern have been reported. Sodium bicarbonate decreases QRS widening and suppresses dysrhythmias by providing excess sodium to reverse the TCA-induced sodium-channel blockade and possibly by binding directly to the myocardium. There are no pediatric case reports on imipramine or other TCA associated toxicity in Korea. Here, we describe a patient who presented with convulsions, tachycardia with a wide QRS complex, a Brugada electrocardiographic pattern, and anuresis associated with an accidental overdose of imipramine and the outcome of treatment with sodium bicarbonate.
