The major function of immune system is to protect infections. The immune systems are composed of innate and adaptive immunity. In adaptive immunity, the cellular and humoral components interact each other. Neonates and infants are infected frequently, because immune systems are naive and easy to expose to infectious agents. The complete history and physical examination is essential to evaluate the child with recurrent infections. The environmental risk factors of recurrent infections are day care center, cigarette smoke, and air pollution. The underlying diseases such as immunodeficiency, autoimmune diseases, allergy, and disorders of anatomy or physiology increase the susceptibility to infections. In immunodeficiency, infections are characterized by severe, chronic, recurrent, and unusual microbial agents infection. The defects of antibody production are susceptible to sinopulmonary bacterial infections. T cells defects are vulerable to numerous organisms such as virus, fungi, bacteria and etc. The screening tests for immune functions are the quantitative and qualitative measurements of each immune components. A complete blood count with white blood cell, differential, and platelet provide quantitative informations of immune components. Total complement and immunoglobulin levels represent the humoral component. Antibody levels of previously injected vaccines also provide informations of the antigen specific antibody immune responses. T cell and subsets count is quantitative measurement of cell mediated immunity. Delayed hypersensitivity skin test is a crude measurement of T cell function. The long term outcome of children with recurrent infections is completely dependent on the underlying diseases, the initial time of diagnosis and therapy, continued management, and genetic counscelling.

This study focused on the relationships among emotionality, eating behavior problems, and behavior problems in a sample of 185 four- to five-year-old children attending kindergarten or a day care center in Seoul. The values were all measured by their teachers. The collected data were analyzed using simple regression and hierarchical multiple regression. The main results of this study were as follows. First, children's positive and negative emotionality each exerted negative and positive effects on their internalizing behavior problems. Second, children's positive emotionality had a negative influence on their eating behavior problems. On the other hand, children's negative emotionality had a positive influence on eating behavior problems. Finally, effect of children's positive emotionality on their eating behavior problems was partially mediated by internalizing behavior problems. On the other hand, the effect of children's negative emotionality on their eating behavior problems was totally mediated by their internalizing behavior problems.

Western missionary nurses practiced in Korea from 1891. and the first trial to begin missionary public health nursing service in 1909 could not put into practice for short of nursing staff and budget. The main focus of missionary medical practice was not in public health program but in the management of missionary hospitals. A few of missionary western R.N. tried district nursing in 1910s. but their activities were personal and focused on the rescue of poor and sick patients. In 1917 the North American Methodist Church dispatched R.N. Elizabeth S. Roberts to begin district nursing in Korea. Roberts began maternal and child district nursing service. Her service was focused on teaching the method of bringing up children. bathing service, and home visiting for delivery. She could not but stop district-nursing service in 1918 to serve for a hospital in Siberia. The North American Methodist Church dispatched a few of R.N. to Korea in early 1920s and the missionary public health nursing of Korea could be activated. R.N. E. T. Rosenberger began public health nursing program in Seoul with Korean graduate nurse, Shin-gwang Han, and missionary M.D. Hall. Their public health nursing program was focused on maternal and childcare. They did home visiting in the morning, and served at a well baby clinic in the afternoon. The first baby competition began in 1925. and contributed to the teaching the method of bringing up children. They expanded public health nursing activity to school health nursing and milk station. Their public health nursing program was such a success that In 1929 Severance hospital. Eastgate Hospital. Taehwa Social Evangelistic center organized Seoul Child Health Union. Maren P. Bording, another missionary R.N. and midwife dispatched by the North American Methodist Church began public health nursing program at Kongjoo in 1924. Her program was focused on the maternal and childcare and close to that of Seoul. She started the first milk station in Korea in 1926. As she was a midwife and could get M. D. license in Korea, her program was more focused on maternal care than that of Seoul. The first day nursery school in Korea and the first graduate course for public health nursing in Korea began at Kongjoo in 1930. As the city of Choongcheongnam Province moved from Kongjoo to Daejeon in 1932, missionary public health nursing service in Kongjoo extended to Daejeon. There were lots of public health nursing program in Korea in 1920s and 1930s by missionary western nurses and Korean nurses. There were 13 missionary public health-nursing center in Korea in 1932. But in the late 1930s. Japan extended colonial war and drove out western missionaries. The missionary service in Korea was daunted. and the missionary public health nursing service could not but shrink.

Background: The seropositivity rate of hepatitis B surface antigen (anti-HBs) antibodies is known to be ≥95% after hepatitis B virus vaccination during infancy. However, a low level or absence of anti-HBs in healthy children is discovered in many cases. Recent studies in adults reported that a reduced anti-HBs production rate is related to obesity. Purpose: To investigate whether body mass index (BMI) affects anti-HBs levels in healthy children following 3 serial dose vaccinations in infancy. Methods: We recruited 1,200 healthy volunteers aged 3, 5, 7, or 10 years from 4-day care centers and 4 elementary schools. All subjects completed a questionnaire including body weight, height, and vaccine type received. Levels of serum hepatitis B surface antigen (HBsAg) and anti-HBs in all subjects were analyzed using electrochemiluminescence immunoassay. The standardized scores (z score) for each sex and age were obtained using the lambda-mu-sigma method in the 2017 Korean National Growth Charts for children and adolescents. Results: Our subjects (n=1,200) comprised 750 males (62.5%) and 450 females (37.5%). The overall anti-HBs seropositivity rate was 57.9% (695 of 1,200). We identified significant differences in mean BMI values between seronegative and seropositive groups (17.45 vs. 16.62, respectively; P<0.001). The anti-HBs titer was significantly decreased as the BMI z score increased adjusting for age and sex (B=-15.725; standard error=5.494; P=0.004). The probability of anti-HBs seropositivity based on BMI z score was decreased to an OR of 0.820 after the control for confounding variables (95% confidence interval, 0.728-0.923; P=0.001). Conclusion: There was a significant association between anti-HBs titer and BMI z score after adjustment for age and sex. Our results indicate that BMI is a potential factor affecting anti-HBs titer in healthy children.
