청각의 중요성은 새잠스럽게 말활 필요도 없고 농아가 말못하는 것은 누구나 다 알 수 있는 사실입니다. 그러나 음을 하나하나 습득하고 단어를 하나하나 반복하면서 언어습득을 시작하는 유년기에 있어서 청각은 더욱 독특한 역활을 합니다. 조국에 돌아와서 일하기 시작한지 일년이 조금 넘었으나 최초부터 우리 연구소에 찾아오는 어린이가 구주제국보다 훨씬 연소하고 또 수가 훨씬 많은 데 놀랐습니다. 그 중 대다수가 조음장애라든가 언어지연입니다. 더욱 놀라운 점은 이러한 장애가 정상지능의 어린이에게 많은 것입니다. 일반상식으로 어휘력과 발표력이 부족한 어린이들은 정신지체아와 혼동하게 됩니다. 연구소에 진단받으러 오는 어린이들을 체계적으로 청각 검사를 한 결과를 슬라이드를 통해서 말씀드리겠습나다. 검사받은 어린이 중 50-60%가 청각에 이상이 있는 것이 발견되었습니다. 동반한 어머니들은 너무나 놀라서 "우리 아이는 검사를 받았어요! 모두 정상이라고 그랬어요" 이 엄마 말씀도 정당하고 전검사도 정당활 것입니다. 그러나 이러한 어린이들의 문제는 특수합니다. 즉 경도난청에다 또 일시적 난청이기 때문에 명시에 생활하는 데는 큰 지장이 없고 때에 따라서는 청각이 거의 완전히 회복되고 또 몇 주후에 감기가 들거나 하면 다시 난청이 되는 것입니다. 이러한 난청문제가 일년에 3-4번씩 반복되어 어린이가 만 3-4세가 되면 약 1년간 청확한 음을 청취못한 셈이 됩니다. 조석에 기온차가 대단한 계절, 난방의 발달로 인하여 실내는 영상 24도이고 문 한겹만 열고 나가면 영하 10도 그 차이는 34도, 거리로 나가면 일산화탄소를 뿜고 쾌주 하는 차량, 버스나 트럭에셔 나오는 연기는 키가 작은 어린이 코속으로 직통하고 에어컨 시스댐으로 난방.냉방하는 지하상가, 백화점, 지하철 기타 대건물에는 바이러스 만연의 적절한 곳이 됩니다. 생리적 저항력이 없는 어린이들은 이러한 공해와 생활조건의 제일희생자가 되는 것입니다. 엄마들이 "얘는 감기, 비염, 편도선을 달고 삽니다...." "얘는 코감기, 목감기 번갈아 가면서 하도 앓고 있어서 양약율 중지하고 현재 한약을 먹고 있습니다." 이러한 역경은 극복할 수 있는가\ulcorner 질병의 메카니즘은 어떻게 작용되는가\ulcorner 등등을 육미회 센타에서 체험한 사례를 가지고 말씀드리고자 합니다.

Children need regularly dental check-ups after dental treatment because there are a lot of changes of oral conditions such as tooth exfoliation and eruption, occlusion, and recurrence of dental caries. The purpose of this study is to determine the factors that affect the follow-up pattern after dental treatment under conscious sedation. Patients who were treated under sedation at the department of pediatric dentistry of Ewha Womans University Mokdong Hospital from 2009 to 2013 were included in this study. The final samples comprised of 562 patients that were classified into 4 groups according to the number of visits during 3 years. The chi-square test was used to determine the factors affecting regular follow-up. There were statistically significant differences between each treatment groups and factors such as the change of doctor, overall treatment time, the number of treated teeth under sedation, restorative treatment, minor operation, and preventive treatment (p < 0.05). This study identified factors that affect regular follow-up after dental treatment under conscious sedation. It is recommended to educate the importance of regular check-ups to parents who are less likely to return.

This study was designed to investigate the effect of early protein undernutrition of rats on later susceptibility to lead poisoning. Weanling rats, weighing about 55 grams, were malnourished by feeding low protein diets ( 12% and 5% casein diet ) during the four weeks of protein deprivation period. For the following 5 weeks, the malnourished rats were fed with 25% casein diet as rehabilitation diet. After the rehabilitation period, all rats were fed with 25% casein diet and the drinking water containing 2000ppm-Pb during the four weeks. The results obtained were as follows ; 1 ) Feed intake, body weight gain and food efficiency ratio were reduced in all rats exposed to lead, especially in rats fed with 5% casein diet during the four weeks of weanling period. 2 ) Enlargement of kidney and spleen were observed in all rats exposed to lead and were more remarkable in rats fed with 5% casein diet. 3 ) In rats exposed to lead, activity of serum glutamic oxaloacetic transaminase ( S- GOT ) was significantly increased by increasing the degree of early protein deprivation, whereas hematocrit value was significantly decreased. Activity of serum glutamic pyruvic transaminase ( S- GPT ) was shown a tendency to increase by increasing the degree of early protein deprivation, but the difference was not significant. 4) In rats exposed to lead, the amount of lead accumulation in kidney was increased by increasing the degree of early protein deprivation. The significant increase was shown in rats fed with 5% casein diet during the four weeks of weanling period. The results of the experiment suggest that early protein undernutrition, even after some period of rehabilitation, may enhance the later susceptibility to lead poisoning.

Helicobacter pylori(H. pylori) has been associated with the cause of peptic ulcer and gastric cancer. H. pylori infection occur mostly during childhood and increase by aging. In route of transmission, Oral cavity does important role. So we employed this study to elucidate route of transmission by detection of H. pylori in infant saliva. We investigated 20 infants aged below 10 years and 20 teens aged below 20 years as study group and 71 adults aged 20 and over years as control group. H. pylori DNA was isolated from 5(25%) infants aged below 10 years, 6(30%) teens and 17(23.9%) adults by nested polymerase chain reaction(n-PCR). There was no statistically significant difference(P>0.05). The obtained results suggest that H. pylori infection is relatively common in saliva of Korean infant and oral cavity may be reservoir of H. pylori.

We investigate the clinical characteristics of odontoma in childhood and adolescence. A retrospective analysis was performed in 105 patients under 15 years old who were diagnosed with odontoma in Kyungpook National University Dental Hospital, the department of pediatric dentistry between 1 January 2008 and 31 December 2013. The ratio of compound odontoma, immature odontoma and complex odontoma were 67.6%, 21.9% and 10.5%, respectively. Odontoma was more prevalent in males and the ratio of males to females was 1.5:1. The age of patients ranged from 3 to 14 years old with an average age of 9.3 years old. The odontoma was more frequently located in the maxilla (73.3%) than in the mandible(26.7%). In 98 cases, it was treated by surgical removal. Among adjacent teeth impacted by odontoma, 26 cases (34.7%) of successional permanent teeth were erupted when only odontoma were removed and 6 cases (8.0%) were erupted when surgical exposure was performed. Orthodontic tractions were performed in 43 cases (57.3%). In conclusion, odontoma could cause complications such as impaction of teeth. If they are found early and treated properly, high eruption success of successional permanent teeth can be obtained. The occurrence frequency of immature odontoma are higher than that of complex odontoma, and they are observed intensively in anterior maxillary teeth. Therefore, it is considered that they are important causes of dental impaction in anterior maxillary teeth.

Common usage of the concept of juvenility implies that there is one physiological phase, the juvenile phase, which manifests itself in the various morphological and physiological phenomena observed in juvenile higher plants. The juvenile phase is often defined as that time from seed germination until the plant attains the ability to flower regulating such behaviour. This definition precludes plants from flowering in the juvenile phase. It is of major interest, therefore, to identify the physiological controls(Bluehreife) regulating such behavior. The length of the juvenile period in higher plants ranges from one year to over 60 years in different species. The long juvenile period of seedling is the main cause of the long duration of the breeding process. I determined the length of the juvenile period in various plants and its control of phase changes in natural system in relation to factors such as plant size and age, shoot morphology, apex size, root system and phytohormonal and nutritional status is reviewed. From the own experimental and observational evidence available it appears that both hormonal and nutritional factors can be involved in control of juvenility but that a specific juvenile or flowering hormone is not involved. Grafting, ringing, scoring, root pruning and fertilization have been used to accelerate flowering, but in most cases these cultured treatments are only successful on plants that were passed the juvenile phase. It is suggested that there are intrinsic difference between the meristematic cells of the apieces of juvenile and adult shoot, which are thus determined with respect to there development potentialities. The problems associated with the maintenance of the determined state through mitosis are discussed. The properties of transitional forms of Ribes nigrum L. intermediate between the juvenile and adult phase, are descrived and there implications discussed. Analogies are drawn between juvenile phenomena in woody perennials and in herbaceous species.

There are many reports of the surgical management for the craniofacial abnormalities arising from the irradiation of the head and face for treatment of childhood cancers. Since the mordern combined-modality theraphy for childhood cancers began in the late 1960s and the early 1970s, recent reports have described the occular, dental and maxillo-facial abnormalities after irradiation in long-term survivors of cancers of the head and face. The resultant deformities may be known to be difficult to reconstruct with surgical techniques. This paper describes the late reconstructive surgery for the unilateral orbital and malar hypoplasia after eyeball enucleation and irradiation during childhood to correct the facial asymmetry and expand the contracted orbital socket into the functional dimension for the retaining eyeball prosthesis with spherical implant. We reports the satisfactory preliminary results from the midfacial osteotomy through the supero-lateral orbital rim and malar bone and the antero-lateral repositioning with the autogenous bone grafting in 26 year-old female patient who will be planned to make the new eyeball prosthesis by the department of ophthalmology.

Colorectal cancer is one of the most steeply increasing malignancies in Korea. Among 398,824 new patients recorded by the Korea Central Cancer Registry between 2003 and 2005, 47,915 cases involved colorectal cancers, accounting for 12.0 % of all malignancies. In 2002, total number of colorectal cancer cases had accounted for 11.2 % of all malignancies. Hereditary syndromes are the source of approximately 5% to 15% of overall colorectal cancer cases. Hereditary colorectal cancers are divided into two types: hereditary nonpolyposis colorectal cancer (HNPCC), and cancers associated with hereditary colorectal polyposis, including familial adenomatous polyposis (FAP), Peutz-Jeghers syndrome, juvenile polyposis, and the recently reported hMutYH (MYH)-associated polyposis (MAP). Hereditary colorectal cancers have unique clinical features distinct from sporadic cancer because these are due to germline mutations of the causative genes; (i) early age-of-onset of cancer, (ii) frequent association with synchronous or metachronous tumors, (iii) frequent association with extracolonic manifestations. The management strategy for patients with hereditary colorectal cancer is quite different from that for sporadic cancer. Furthermore, screening, genetic counseling, and surveillance for at-risk familial member are also important. A well-organized registry can plays a central role in the surveillance and management of families affected by hereditary colorectal cancers. Here, we discuss each type of hereditary colorectal cancer, focusing on the clinical and genetic characteristics, management, genetic screening, and surveillance.

Recentrly, early dental care for children is becoming more important, and the number of children patients' dental services is on the rise. So, a variety of seduction therapies are needed to alleviate the tension in children who are anxious about dental care. This paper describes the development process and contents of system that can display the animation of different stories according to the treatment stage by grasping the use state of the treatment device in real time. In the animation, the hreo character and the villain, the cavity character, appear and the hero defeat the villain at each treatment stage. Animation is played when treatment starts and ends after treatment. Current existing one-side played animation of dental clinics is not enough to attract children's attention. If the flow of animation changes depending on the treatment process, it will give children a different enjoyment and consequently ease the tension over the treatment.

Alexithymia is characterized by difficulties identifying and describing feelings, impoverished fantasy life, and concrete and poorly introspective thinking. Alexithymic patients have been reported to show a stable deficit with regard to processing and regulating emotions. Eating disorders are characterized by a persistent disturbance of eating or eating-related behavior that significantly impairs physical health or psychosocial functioning. Like alexithymic patients, patients with eating disorders show the impaired capacity to process and regulate emotions. There is a robust body of literature showing patients with eating disorders are more alexithymic than healthy controls. Specifically, patients with eating disorders experience difficulties identifying and describing emotions. Childhood maltreatment can increase the risk for depression and alexithymia, which can in turn lead to disordered eating symptoms. Also, higher levels of alexithymia are correlated with a less favorable clinical outcome in patients with eating disorder. Therefore, treatments to help processing and regulating emotions of eating disorder patients with pronounced alexithymic traits may seem to lead to a higher possibility of recovery.
