The purpose of this study was to identify the mediating effects of self-esteem in the relationship between marital conflict and school adjustment among adolescents. This study used data collected from 482 middle school students in Seoul. Multiple regression analysis was used to examine the mediating effects of self-esteem in the relationship between marital conflict and school adjustment. The results of this study revealed that there were sex differences in self-esteem of adolescents. For both male and female adolescents, marital conflict was found to have negative effects on self-esteem. School adjustment of adolescents was found to be positively influenced by self-esteem. Marital conflict had negative direct effects on school adjustment only for male adolescents. Results indicated that self-esteem mediated in the effects of marital conflict on school adjustment for male and female adolescents. Implications for understanding the associations among marital conflict, children's self-esteem and adjustment in school contexts were discussed.

Periodontal disease as one of oral diseases is a chronic disease that continuously worsens once it occurs. It begins with gingivitis in the late school childhood. Its prevalence rate gradually increases in adolescence and continues to rise until young and middle ages. Therefore, the preventive care for the disease in one's whole life is of very importance. Since periodontal disease can be prevented and controlled by oral health behaviors, this study focuses on the relation between adults' oral health behaviors and the disease and emphasizes its importance. Based on the data of the 2015 6th (3rd Year) National Health and Nutrition Examination Survey, the prevalence rate of periodontal disease was compared according to study subjects' oral health behaviors. As a result, gum disease treatment, the count of gum brushing, use of dental floss use of interdental brush, and subjective oral health condition were statistically meaningful. Given that oral health behaviors are related to periodontal disease, it is necessary to conduct a systematic study for developing and performing the oral health education program to make the right habit of oral health behaviors.

This study is about a life history. Through investigating the life of retired teachers in preschool, elementary, and middle schools, authors wanted to explore the meaning of retirement and the process of adaptation to find out their personal and social needs in post-retirement life. Studies have shown that their experiences at childhood have greatly influenced the performance of one's profession, such as contributing to setting limits on behaviors of their students. In the period of interdependence, they have contributed to serving society and the nation beyond as a professional, and in the second half of his teaching career, they have learned that their painful experience was a resource and have realized that changing mind can make the world changed. Since teachers' behavior affects on many subjects unlike other jobs, rewards or satisfaction from the job was bigger than any other jobs. However, after retirement, they felt a sense of emptiness in life without any sense of belonging or accomplishment, while feeling happiness and infinite freedom in other hand. Thy still go forward for life challenging to new study.

Objectives Maltreatment experiences can alter brain function related to emotion regulation, such as cognitive reappraisal. While dysregulation of emotion is an important risk factor to mental health problems in maltreated people, studies reported alterations in brain networks related to cognitive reappraisal are still lacking. Methods Twenty-seven healthy subjects were recruited in this study. The maltreatment experiences and positive reappraisal abilities were measured using the Childhood Trauma Questionnaire-Short Form and the Cognitive Emotion Regulation Questionnaire, respectively. Twelve subjects reported one or more moderate maltreatment experiences. Subjects were re-exposed to pictures after the cognitive reappraisal task using the International Affective Picture System during fMRI scan. Results The maltreatment group reported more negative feelings on negative pictures which tried cognitive reappraisal than the no-maltreatment group (p < 0.05). Activities in the right superior marginal gyrus and right middle temporal gyrus were higher in the maltreatment group (uncorrected p < 0.001, cluster size > 20). Conclusions We found that paradoxical activities in semantic networks were shown in the victims of maltreatment. Further study might be needed to clarify these aberrant functions in semantic networks related to maltreatment experiences.

Congenital hereditary disease is in devided into Infantile type and Adult type, Adult type is hidden for many years and keeps normal renal function till middle age. Cyst is stimultaneously made in both sides and becomes lowered in renal function in 30's to 40's. Infantile type is generally born with the big kidneys, renal failure, undergrowth of intrahepatic bile duct. Both infantile and childhood type have ureteral dilatation and portal hypertension In infantile type, it is mostly developed into renal failure, but generally faces death as a result of hepatic disease. The reason of death is that an abnormal condition of recessive autosome affects the liver and kidneys. While the incidence of infantile type is rare as $0.017{\sim}0.07%$ and it is autosomal recessive heredity, Adult type can rarely exist in infantile period. Though it exists in middle period, 50% of patients can live for 2-4 years after the first symptom incidence and 25% can less than 2 years. It is hard to cure completely in medicine and surgery. Three difficulties in familial incidence are comparative decrease of the donor who have no affection on renal transplantation. For another consideration it is to show the family history for several generations. We, the Med. Dept. of Dae Han Kyouk Life Insurance Co. Ltd., used the ultrasonic apparatus in diagnosing the one case of adult type bilateral polycystic kidney and then doubted the family history. As a result of inspecting the family we experienced bilateral polycystic kidney from 3 persons out of 4 who can be inspected. The results are as follows: 1) We could confirm the polycystic kidney from 3 persons out of 4(75%). 2) Then when they came for check up, chief complaint was the pain in all 3 cases(100%). 3) Accompanying disease was hypertension in 2 cases(67%). 4) In early disease incidence, we couldn't observe the specific change in pathological opinion. 5) All 3 cases are not accompanied with cystic lesion in liver, spleen, pancreas.

Purpose: To evaluate the aspect of occurrence and transition of the elbow injuries in baseball players from childhood to adult. Materials and Methods: We had a survey and took the simple X-ray from the anteroposterior view and the lateral view of both elbows for subjects of total 320 baseball players. - each of 80 players in elementary school, middle school, high school, and professional baseball players between January and December in 2004. Results: The region of pain and the bony changes in elbow were the most frequent in medial side from all the groups of players. Especially, hypertrophy of medial epicondyle were the most numerous. As baseball players got older, the radiological changes of elbow were increased. The bony changes were found out 52 cases (65%) of the elementary school players, 66 cases (82%) of the middle school players, 68 cases (85%) of the high school players and 70 cases (88%) of the professional players out of the total 320 baseball players. Conclusion: The bony changes of the elbow in baseball players got frequent as they were getting older and increased in comparison with past.

Asthma and allergic diseases are one of the most common disorders in children. Due to its increased prevalence, as well as the increased morbidity and mortality from these diseases, asthma and allergic diseases have come to be recognized as a major worldwide public health issue. In addition, socioeconomic burden of asthma and allergic diseases has increased in Korea also. The International Study of Asthma and Allergies in Childhood (ISAAC) investigated the worldwide prevalence of asthma and other allergic diseases using simple standardized methods because of the comparison of asthma and allergic diseases between the countries. In Korea, several epidemiologic studies have been conducted to determine the prevalence of asthma in children. Although these studies showed increased prevalence of asthma among Korean children (from 3.4% in 1964 to 10.1% in 1989), these findings were based on data from small numbers of subjects. The first Nationwide Study of Asthma and Allergies in Korean Children, which utilized the Korean version of ISAAC written and video questionnaire, was conducted in 1995 and the second Nationwide Study of Asthma and Allergies in Korean Children was conducted in 2000, directed by the Korean Academy of Pediatric Allergy and Respiratory Diseases. We report here the prevalence of asthma and other allergic diseases in Korean children and adolescents, and show the changes that occurred over this 5 year period. We also describe the risk factors for development of these diseases in Korean children. We developed Korean versions of the ISAAC written (WQ) and video (AVQ) questionnaires for allergic diseases. In 1995, the enrolled population consisted of 25,117 children selected from 34 elementary school and 14,946 children selected from 34 middle school across the nation, the response rate was 94.8%. In 2000, 27,831 children selected from 34 elementary school and 15,214 children selected from 34 middle school, and the response rate was 96.4%. From these studies, we can confirm that increase of the prevalences of asthma, allergic rhinitis, and atopic dermatitis in Korea, except the prevalence of food allergy. Especially, the video questionnaire showed increases in the lifetime and 12 month prevalence rates of wheeze at rest, exercise-induced wheeze, nocturnal wheeze, nocturnal cough, and severe wheeze over this period of time in middle school children. In addition, the increase of prevalences of symptoms, diagnosis and treatment of atopic dermatitis was noted significantly. Risk factor analysis showed that body mass index (BMI), passive smoking and living with a dog or cat were associated with higher risk of wheeze. Also the occurrence of fever during infancy and the frequent use of antibiotics were associated with the risk of wheeze. In conclusion, during the 5 year period from 1995 to 2000, the prevalences of asthma, allergic rhinitis, and atopic dermatitis has increased in Korean children. BMI, passive smoking, living with a dog or cat, the fever episodes in infancy, and the frequent use of antibiotics in infancy are important risk factors to development of asthma and atopic dermatitis. In the near future, the birth cohort study will be needed to investigate the causes of this increase and the natural course of allergic diseases, then we develop the methods to control asthma and allergic diseases.

Sialolithiasis is the formation of calcific concretions within the ductal system of major or minor salivary glands. The submandibular gland is most involved because of its high viscosity of the saliva and the long, curved duct. It may occur at any age but, it is most common in middle-aged adults and rare in childhood. Clinical symptoms in sialolithiasis are variable but, swelling is the most common, followed by the pain. Clinical examination and radiographic examination(panoramic and mandibular occlusal radiographs, sialography, intraoral-, extraoral- ultrasound, CT scan, MRI and sialoendoscopy) can help to confirm a diagnosis and localize a stone. The treatment is surgical intervention, either removal of the sialolith or sialoadenectomy. However, non-invasive techniques including shock-wave lithotripsy, $CO_2$ laser and endoscopic treatment used in selected cases. A 5-Year-old girl referred from private practice for evaluation of a yellowish mass on the floor of the mouth. She complained that it had became three times bigger than four months ago when it was found for the first time and she had some pain on submandibular gland area occasionally. On physical examination, a firm and yellowish mass could be seen at the orifice of the submandibular duct. Diagnosis is the submandibular sialolithiasis in the anterior Wharton`s duct. Under local anesthesia, stone was removed.

The objective of this study was to understand the degree of conflict in team teaching nursery teachers and also differences in conflict management methods and job satisfaction in accordance with conflict level. For this, a survey was conducted targeting 241 team teaching nursery teachers. In the results of the study, conflict management methods in accordance with conflict level of team teaching nursery teachers showed significant differences in the type of 'integration' and 'avoidance' between groups. Second, job satisfaction in accordance with the conflict level of team teaching nursery teachers showed significant differences in the whole like 'director's operation method & attitude', 'social perception & treatment', 'childcare environment and welfare', 'childcare work', 'relation with colleagues', and 'relation with parents' between groups. In other words, the group with low conflict showed higher job satisfaction than groups with middle or high conflict levels. Based on the results of the study, the efficient operation of team teaching nursery teachers was also discussed.
