Since the introduction of chemotherapy for the treatment of childhood leukemia more than 50 years ago, the results of childhood cancer have improved dramatically. The 5-year survival rate of disease, many of which were uniformly fatal in the prechemotherapy era, reached to more than 75%. This remarkable improvement in survival is a direct result of the incorporation of chemotherapeutics into treatment regimens that previously relied only on surgery or radiotherapy for the primary tumor. The multimodality approach, which integrates surgery and radiotherapy to control local disease with chemotherapy to eradicate systemic or metastatic disease, has become the standard approach to treating most childhood cancers. The overall improvement in outcomes in childhood solid tumors has been related to the development of multidisplinary cooperative studies that has permitted the development of well-designed tumor treatment protocols characterized by uniform staging criteria, sharing informations in pathologic classification, uniform methods for tumor markers, oncogenes, and other biologic and genetic factors. Important advances in the biologic study of cancer and its genetic basis led to a number of observations that impact directly on the management of childhood solid tumors. Identification of specific genes, oncogenes, tumor markers, and other biologic and pathologic factors plays an important role in both staging and clarifying the risk categorization of individual patients. Treatment of the patient is influenced by the recognition of specific risk factors. This knowledge has resulted in a change in the approach to care based not only on staging criteria, but also on risk-based management. This concept uses various risk factors of outcomes. Risk-based management allows for each patient to maximize survival, minimize long-term morbidity and improve the quality of life, especially for children's growth and development.

Mathematics educators oriented to reform-based curricular have asserted that mathematics teachers should lead instructions where all students in their classrooms are able to participated. In this paper, some practices for them to implement it are discussed. Before explaining them, some discussions are made about students ability to construct knowledge. One of them is that teachers should know different learners construct different understandings because of their differences of prior knowledge and reasoning ability. Also, it was discussed that teachers consider classroom environments, assigning children's sitting and tasks in the light of learning. The reason to state them is that perspectives of them should be changed. Finally, "Teacher's careful listening to learners' responses", "Why do think in that way?, How do you know?, What is it meant?", "accepting ideas from all learners", "no supporting a particular idea", "utilizing waiting time", and "teacher's responses to learner's errors and mistakes" are discussed as practices for letting all learners be participated in the mathematics instruction.

This study was undertaken to obtain the data age determination following the eruption of individual cusps of the first molars in the point of forensic odontology. 532 children (294 male and 238 female, born between April, 1989 and March, 1986) from a kindergarten and a primary school in a reesidential district in Seoul were studied. The eruption state of the first molar was divides into 6 stages according to the degree of exposure of individual cusps, and correlation between the stage and age was stastically analysed. The results of the study lead to following conclusions : 1. The most frequently seen eruption sequence of cusps for the upper first molar was mesibuccal cusp, mesiopalatal cusp, distobuccal cusp, mesiodistal cusp, distopalatal cusp. As for the lower first molar : mesiobuccal cusp, mcsiolingual cusp, distobuccal cusp, distolingual cusp. 2. The time of eruption was earlier in the female ethan in the male, but it was stastically remarkable only in upper and lower parts of the right and the left teeth of subjects age between 6.0 and 6.5 and upper part of the right and the left teeth of subjects age over 7.5 3. The eruption of the lower first molar was comparatively earlier than that of the upper first molar and there was no significant stastical difference between the right and the left first molars in the time of eruption. 4. There was no noticeable difference in the eruption sequence of cusps, irrespective of sex and side. 5. The eruption of the upper first molar is started at the age of about 6.4 and complete the age of about 7.1 and as for the lower first molar, it is from 6.3 to 7.0

Untreated cryptorchidism contributes to infertility and may play a role in increasing the risk of malignancy. The appropriate time of operation was considered before school age in 1970s, 2 years of age in 1980s, and between 1 and 2 years of age from 1990s to present time. Orchiopexy is the most common operation for congenital urological problem of children. We analyze our experience of orchiopexies to evaluate the results and to identify the role of the pediatric surgeon. We reviewed the medical records of 91 patients who underwent orchiopexy from January 1996 to December 2007. The patient age at orchiopexy were as follows: 48 cases (52.7 %) under 2 years of age, 24 cases (26.4 %) between 3 and 5 years, 16 cases (17.6 %) between 6 and 10 years, and 3 cases (3.3 %) over 11 years. Location of testes was preperitoneum in all 91 cases. There were 84 unilateral and 7 bilateral cases. Among the unilateral cases, the undescended testes were on right side in 54 cases and on the left side in 30 cases. The surgical procedure employed in all cases was trans-inguinal orchiopexies. Seventy-nine patients had excellent results. There were 12 complications; 5 cases of wound infection and 7 cases of temporary incomplete descent. Seven cases of incomplete descent have become normal from 3 to 6 months after orchiopexy. According to our results, 43 cases (47.3 %) underwent orchiopexies over 2 years of age. In conclusion, orchiopexies were successful in most cases of cryptorchidism in terms of testicular position and growth. We suggest that pediatric surgeons should educate their primary care physicians and parents concerning the potential complications of cryptorchidism and the appropriate time of operation.

This study analyzed storytelling in mathematics textbooks for third graders, which had been developed according to the 2009 revised mathematics curriculum. Storytelling are supposed to be composed of elements such as message, conflicts, characters, and plot, all of which should be consistent with and focused on unit contents. Especially, conflicts in storytelling should be so obvious that children can take an initiative in learning tasks to solve the problems required by the tasks. The analysis of storytelling in the introduction part in teacher's guides for the third-grade textbooks indicates the following: 1) messages are unclear; 2) conflicts are frequently absent (if any, they are unclear); 3) incidents attributable to textbook characters are insufficient; and 4) plots often lack plausibility. In order to achieve the purposes for which storytelling in mathematics textbooks is intended, storytelling should be reconstructed and improved, taking the roles that each component should serve into consideration.

Purpose: This study was conducted to construct evidence based clinical guidelines and to develop nursing process based performance measures for prevention and management of pressure ulcers, falls and pain. Method: Clinical guidelines were drafted through a comprehensive review of relevant literature, national guidelines and hospital protocols. The proposed guidelines were reviewed by a panel of experts and 90 hospital nurses, and refined on the basis of their suggestions. Nursing process based performance measures were developed based on the clinical guidelines and content validity was examined by surveys from 90 hospital nurses. Results: All items, except timetable for position change and pressure ulcer nursing record, in the guidelines for prevention and management of pressure ulcer were appropriate. Most items, except fall risk assessment tools, were appropriate for the guidelines of fall prevention. All other items, except the purpose of pain management, were appropriate for the guidelines of pain management. Performance measures developed in this study were acceptable as a tool to evaluate quality of nursing care. Conclusion: Nursing process based performance measures provide important indicators to monitor whether necessary nursing care is implemented and can be used as the primary resources to improve quality of nursing services.

Introduction In order to improve medical education through the introduction of a concept of comprehensive health care of a community, an area surrounding the University Campus was chosen for the Community Health Service Project. It has been on operation for last 4 years with its major emphasis on family planning services, and maternal and child health care. The major objectives of this survey at the area are to obtain: 1) The demographic data, 2) The health need and trend of medical care, 3) The attitude and practice in maternity care to be used for further improvement of the planning and the services of the project. Population and Survey Method Out of three Dongs of the Community Health Service Area, only two Dongs namely Changchun and Yonhee were selected for the survey. Total number of households and population in the area studied was 3,683 and 21,857 respectively. An interview was performed with questionnaire schedule which was recorded by interviewers. This includes the degree of utilization of health services provided by the Community Health Service Program such as family planning, prenatal care during their last pregnancy, delivery history and complications of the delivery as well as the incidence of illnesses in general. Prior to the interview, all interviewers were trained for interviewing technique for two days. The survey was carried out during the period from October December 1967. Results 1) Demographic Data : 41.3% of the population studied were children under age 15 and only 3.5% were over 60 years of age. Crude birth rate and crude death rate of this area studied during the period of November 1966-October 1967 were 20.5 and 7.7 respectively. Infant mortality rate during the same period was 35.9. 50.4% of the 2,832 households fell into the category of middle class, 39.8% to the lower class and 9.5% to the upper class in economic condition. 19.8% of 2,832 householders had no formal education, 22.7% primary school, and 57.5% middle or higher school education. 2) Health Status and Utilization of the Community Health Service: Those who suffered from many illnesses during the month of October, 1967 were 690(4.6% of 14,891 persons). Classification of these patients into the type of disease shown respiratory diseases 27.4%, gastrointestinal diseases 18.1%, tuberculosis 10.9%, skin and genitourethral diseases 4.5% and gynecologic patients 4.5%. Only 55.9% of the patients received medical care at hospital or doctor's clinic. But among TB and gynecologic patients, 70.7% and 72.4% were treated at medical facilities. 10.6% of 2,832 householders interviewed has ever utilized the Community Health Service Program provided by the Yonsei Medical School, Classifying these clients into the type of service, 35.9% utilized the wellbaby clinic, 31.0% the family planning clinic, 14.7% the home delivery care, and the rest utilized other services such as the premarital guidance cinlic and the sanitary inspection service. 3) Maternity Care: 23.6% of 2,151 deliveries were done at medical facilities such as hospital, private clinic, while 76.4% were done at home. Acceptance rate of prenatal care was 32.6% as whole, but 49.6 of 774 women who had the prenatal care service had their deliveries at medical facility. 45.1% of total deliveries were attended by medical and or paramedical personnel. 75.8% of the deliveries of those received prenatal care were attended by medical and or paramedical personnel while only 27.8% of the deliveries of those who did not have prenatal care attended by medical and or paramedical personnel. 49.8% of deliveries of the upper class, 29.8% of the middle class and 9.9% of the lower class were attended by medical and or paramedical personnel. 6.2, 3.3% and 24.8% of mothers reported about their xeperience of edema, coma and fever during the period of trimester of pregnancy and puerperium. 4) Family Planning: The rate of practice of family planning was 27.9%. 31.7% of them were by IUD, 2.9% by oral pill, 15.2% by sterilization and the rest by traditional methods. Those women who had 3 to 4 children had highest(30.2%). Practice rate among the various methods of family planning, oral pill was the most popular method to whom had 2 or less children. In relation between the practicing rate of family planning and living standard, the upper, middle and lower class practiced 37.5, 29.4 and 19.9% respectively.

The main purpose of this study is to examine the concepts appeared on researches and provide the future research directions in field of child health nursing. A descriptive study was conducted. 205 studies were included in an analysis the concepts in terms of the domain of client for a total 321 researches. All were originally published between 1990 and 2000 in Korea. An analysis of concepts for this study was used the metaparadigm framework for nursing proposed by H.S. Kim(2000). The concepts for this study were categorized by essentialistic concepts, problematic concepts, health-care experiential concepts with the following results. 1. Based on the four domains suggested Kim (2000), 205 studies(63.9％) belong to the domain of client ; 109 studies(34％) belong to the practice domain of nursing; 3 studies(0.9％) belong to the client-nurse domain; and 4 studies belong to the domain of environment, respectively. 2. In the domain of client, 117(57.1％) studies used concept of parent. Among them, mother was the prevailing research population(103 studies). 64 studies(31.2％) used child population and the developmental stage of children varied from preterm to puberty but school aged children was the most target population(28 studies). Family as a concept of client was used in 20 studies(9.8％) but most primary care provider was the mother. 3. In terms of research design, non-experimental design(83.5％) is the most and among them survey was 159 studies(77.6％). Qualitative research(23 studies) and experimental research(10 studies) methods were used relatively few. 4. In terms of the categories of concepts, 196 (61.4％) studies included the essentialistic concepts like stress and coping(20.4％), mothering role and child care(7.8％), health (5.6％), breast feeding(4.7％). 31 studies included problematic concepts like power-lessness, safety, obesity, pain, anxiety. And 65 studies included health-care experiential concepts like compliance, growth, hope, environment but relatively few. The findings of this study provide the evidence that research related problematic concept and health-care experiential concept should be conducted actively to improve the practice of child health nursing. Also to deeply understand the phenomena of client in field of child health nursing, interpretive research methods should be conducted actively, too.

The purpose of this study was to invent anger-inducing automatic thoughts examination for elementary school children based on its investigation for Korean one. I made the anger-inducing Automatic Thoughts Questionnaire(I, II) and made an examination of the contents of the automatic thoughts with it. Based on it, with preliminary questionnaire 90, I did principal component analysis varimax rotation and then final anger-inducting automatic thoughts examination of 40 question in 2 primary factor construction was consisted. I made 300 students carry out it to know its reliability, propriety and made 100 students carry it out at 2-week intervals test-retest. I divided them in three groups as low, middle and high according to its soore regarding anger-inducting automatic thoughts, I confirmed the variation of each group in positive thoughts, self-esteem, life satisfaction, anger, the result is same as follows; First, the content of Anger-inducting Automatic thoughts for elementary school students is revealed as unreasonableness(56.4%), retailation and passive, active offense(16.3%), blame and contempt(11.9%), injured pride and refusal(9.2%), absurd(3.9%), abandonment and avoidance(2.1%), self-abasement in turn. Second, said inventory is consist of 2 notion; first(20 questions) is blame, retaliation and second(20 questions) is injustice. Inner-item consistency of total 40 question is .97, Split-half reliability is .93, Test-retest reliability is .86. Third, criterion validity is revealed fine by reviewing the correlation between existing index related to the inventory of Anger-inducting Automatic thoughts of the elementary school students. Moreover, to find out discriminant validity, I divided three classes(low, middle, high) according to the score of said thoughts. As a result, there is certain variations when I confirmed variations in groups by reviewing the self-esteem, positive way of thinking, life satisfaction, anger.
