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 investigate of gender difference on dietary behavior and food preferences of elementary school children. This survey was carried out through questionnaire method for 274 male and 257 female of the 6th grade elementary school children in Anyang city. By calculating WLI(weight-length index), 26.9% of students were overweight, and 26.2% were under-weight. Average height of male was 147.9cm and that of female was 148.9cm, and their weight was 40.9 kg and 39.2kg respectively. The average BMI(body mass index) was 18.1 kg/㎡. The self-recognition of health status was different according to gender, male recognized better health status than female. There was no significant difference of parents´ education level and the occupation depending on gender. The 56.7% of students had regularly for breakfast, and 60% for lunch and 42.9% for dinner. The female students had irregular meal time more frequently than male did for dinner(p<0.01). They skipped more breakfast(7.0%) than other meals. Reasons of skipping meal were lack of time to eat(50%), boring side-dishes(17.0%) etc. For snacks, choice depends on taste (55.4%), and they bought at the shop nearby (36.5%) and convenience shop(29.9%). They had a meal outside once a month(42.9%), and selected Korean traditional food(52.5%). For almost all of foods male students´ preference showed higher than female except cucumber. Low score of preference was obtained in such as salted vegetables, soy pastes, and fish(shellfish) groups raw or fermented. The preference level was a little higher in such as vegetables & kimchi group and pot stews. The results assert the importance of nutrition education for the students in puberty. It is necessary breakfast should be taken regularly, and therefore we should carry out the education of importance of nutrition and health for children considering the dietary behavior and food preference for balanced diet.

Treatment timing is a very important factor to consider in treating skeletal Class III patients by means of maxillary protraction. According to the literature maxillary Protraction should be carried out at an early age before puberty. However, no scientific data were presented to support this statement and recent studies supported by statistical data showed disagreement concerning the optimum treatment time of maxillary protraction. Therefore, there is no agreement about the optimum treatment time of maxillary protraction. In this study hand-wrist X-rays were taken from 119 patients and subjects were grouped into prepubertal and pubertal group according to their skeletal maturity. Pretreatment and posttreatment lateral cephalometric X-rays were taken and treatment effects were compared. The average treatment time was 6.5 months for the prepubertal group and 6.1 months for the pubertal group. The obtained results were as follows ; 1. The amount of maxillary forward movement was the same for Pretreatment and pubertal group. 2. The amount of maxillary downward movement was the same for prepubertal and pubertal group. 3. The amount of mandibular downward and backward rotational movement was the same for prepubertal and pubertal group. 4. Dental effects were the same for prepubertal and pubertal group.
This study aimed to present cosmetic countermeasures for preventing fast aging process in the middle age and accepting healthy aging both physically and mentally by investigating the perception of aging according to the health condition, lifestyle and psychological condition targeting mid-aged women in 40s to 50s residing in Seoul and Gyeonggi-do Province. The data collection period was from July 25 to Sept 1, 2015. The data was analyzed by descriptive statistics, t-test, ANOVA, Pearson's correlation coefficients, and stepwise multiple regression. It was shown that as the age was higher, the menopause ratio was higher, drinking, exercise volume and hours of sleep were reduced and the stress and psychological pressure were higher. According to the menopausal status, the status of facial aging showed a significant difference (${\chi}^2=39.692^{***}$, p<.001), and it also showed a difference according to the status of leisure (hobby) activity (${\chi}^2=22.470^{***}$, p<.01). Also, as higher the age and closer to the menopause in items including the progress of aging, anxiety about aging and improvement efforts, more negative perception was shown, indicating that it is necessary to prepare cosmetic countermeasures for mid-aged women in like a second puberty 40s to 50s although aging and menopause around 50s are very natural. If a beauty alternative is provided, it will help them to have a successful retirement.

Acne is an inflammatory skin disease that occurs in puberty and young people. Propionibacterium acnes (P. acnes) is known to be a major cause of inflammation in acne. P. acnes proliferates within hair follicles blocked by overproduced sebum in the skin, and thereby activates monocytic cells to promote the secretion of pro-inflammatory cytokines. In this study, we investigated the possibility of Cnestis palala (Lour.) Merr. extract to diminish P. acnes-mediated inflammatory responses. We found that C. palala extract significantly attenuated P. acnes-induced pro-inflammatory cytokine expressions, such as $IL-1{\beta}$, IL-6, $TNF-{\alpha}$, iNOS, and COX-2 in mouse macrophage RAW264.7 cells. Moreover, we observed that C. palala extract inhibited $NF-{\kappa}B$ transcriptional activation, which is the major transcription factor of inflammatory cytokine expression. Therefore, it is expected that C. palala extract has a potential as a therapeutic agent or supplement for the treatment P. acnes-induced inflammatory responses.

Purpose : This study was performed to evaluate the recent frequency of karyotypes in different sex chromosome abnormalities and to evaluate the age and clinical manifestations at diagnosis. Methods : Peripheral blood leukocytes were obtained from subjects who were clinically suspected to have sex chromosome abnormalities and referred to the cytogenetic laboratory in the Department of Pediatrics, Kyungpook National University Hospital from February 1981 to August 2001. Results : The relative frequencies of different sex chromosome abnormalities were Klinefelter(52 percent), Turner(42 percent), XXX syndrome(3 percent) and mixed gonadal dysgenesis(3 percent). The populations of different karyotypes in Klinefelter syndrome were 47,XXY(97 percent) and 46,XY/47,XYY(3 percent). The populations of different karyotypes in Turner syndrome were 45,X(67 percent,), mosaicism(23 percent), and structural aberrations(10 percent). The populations of different karyotypes in XXX syndrome were 47,XXX(67 percent,) and 46,XX/47,XXX(33 percent). All mixed gonadal dysgenesis were 45,X/46,XY. Eighty one percent of sex chromosome abnormalities was diagnosed after puberty. Patients diagnosed with Klinefelter and Turner syndrome in infancy showed nearly normal phenotypes or had minor congenital malformations. Conclusion : Early diagnoses of sex chromosome abnormalities is required to prevent associated morbidities and to maximize growth and development. We have to pay careful attention in diagnoses of Turner syndrome because of the high proportion of mosaicism and structural aberrations.
In this paper, we develop a cost effective and disposable voltammetric sensing platform involving screen-printed carbon electrode (SPCE) modified with the nanocomposites composed of multi-walled carbon nanotubes, polyelectrolyte, and tyrosinase for bisphenol A. This is known as an endocrine disruptor which is also related to chronic diseases such as obesity, diabetes, cardiovascular and female reproductive diseases, precocious puberty, and infertility. A negatively charged oxidized multi-walled carbon nanotubes (MWCNTs) wrapped with a positively charged polyelectrolyte, e.g., polydiallyldimethylammonium, was first wrapped with a negatively charged tyrosinae layer via electrostatic interaction and assembled onto oxygen plasma treated SPCE. The nanocomposite modified SPCE was then immersed into different concentrations of bisphenol A for a given time where the tyrosinase reacted with OH group in the bisphenol A to produce the product, 4,4'-isopropylidenebis(1,2-benzoquinone). Cyclic and differential pulse voltammetries at the potential of -0.08 V vs. Ag/AgCl was employed and peak current changes responsible to the reduction of 4,4'-isopropylidenebis(1,2-benzoquinone) were measured which linearly increased with respect to the bisphenol A concentration. In addition, the SPCE based sensor showed excellent selectivity toward an interferent agent, bisphenol S, which has a very similar structure. Finally, the sensor was applied to the analysis of bisphenol A present in an environmental sample solution prepared in our laboratory.
CD47 (integrin-associated protein), a multi-spanning transmembrane protein expressed in all cells including red blood cells (RBCs) and leukocytes, interacts with signal regulatory protein ${\alpha}$ ($SIRP{\alpha}$) on macrophages and thereby inhibits phagocytosis of RBCs. Recently, we generated a novel C57BL/6J CD47 knockout ($CD47^{-/-}$ hereafter) mouse line by employing a CRISPR/Cas9 system at Center for Mouse Models of Human Disease, and here report their hematological phenotypes. On monitoring their birth and development, $CD47^{-/-}$ mice were born viable with a natural male-to-female sex ratio and normally developed from birth through puberty to adulthood without noticeable changes in growth, food/water intake compared to their age and sex-matched wild-type littermates up to 26 weeks. Hematological analysis revealed a mild but significant reduction of RBC counts and hemoglobin in 16 week-old male $CD47^{-/-}$ mice which were aggravated at the age of 26 weeks with increased reticulocyte counts and mean corpuscular volume (MCV), suggesting hemolytic anemia. Interestingly, anemia in female $CD47^{-/-}$ mice became evident at 26 weeks, but splenomegaly was identified in both genders of $CD47^{-/-}$ mice from the age of 16 weeks, consistent with development of hemolytic anemia. Additionally, helper and cytotoxic T cell populations were considerably reduced in the spleen, but not in thymus, of $CD47^{-/-}$ mice, suggesting a crucial role of CD47 in proliferation of T cells. Collectively, these findings indicate that our $CD47^{-/-}$ mice have progressive hemolytic anemia and splenic depletion of mature T cell populations and therefore may be useful as an in vivo model to study the function of CD47.

Adolescence is a transitional stage of physical development which occurs during the period from puberty to adulthood. Going through this period, various parts of an adolescent's body grow at different rates, leading to different body shapes and proportions when compared to adults. Therefore, this study aimed to investigate the body sizes and shapes of junior high school boys from ages 13-15 based on body measurement items that are used as the basis for school uniform designs including jackets, shirts, and pants. For this, the study sought the basic data needed to develop body shapes and school uniform patterns for junior high school boys using the data from the 6th Size Korea Survey (2010). Specifically, it provided basic data for the development of school uniform patterns that fit well through the classification of bodies into particular types. After extracting body shape componen a cluster analysis using ANOVA was performed. According to the factor analysis conducted to determine body shape components, 5 factors were obtained as follows: Factor 1: bulk and horizontal size, Factor 2: body height and length, Factor 3: shoulder shape and length, Factor 4: characteristics of horizontal size, Factor 5: shape of the upper body with a variance of 82.62%. To classify junior high school boys' body shape was determined using various characteristics, and a cluster analysis was performed with the variables obtained by the factor analysis. For this, body shapes were classified into 3 different types: Type 1 accounted for 33.4%, with a total of 463 subjects. This type was a tall, long body individual with the smallest bulk and size. Type 2 accounted for 22.7%, with a total of 315 subjects. This type was large in bulk and horizontal size, but the lowest in height and length. Type 3 accounted for 43.9%, with a total of 610 subjects. This type was close to average in terms of horizontal size, length, and height. To develop well-fitting school uniforms for junior high school students, there should be further studies on changes in body shape and their associated causes. The study results will be available as basic data for comparing branded school uniform patterns for junior high school boys and developing school uniform patterns based on body shape, using 3D virtual clothing simulations.

This study was aimed to evaluate orofacial morphologies on the cases of developmental disorders of maxillary first molars. Panoramic radiographs, lateral cephalographs, and clinical photos of 2983 children who attended the Pediatric Dental Clinic of Pusan National University Dental Hospital from 2006 to August 2017 were assessed retrospectively. 34 patients were selected whose maxillary first molars were missed or developmentally delayed unilaterally or bilaterally. Demirjian's method was used for estimating dental age, then which was compared to chronologic age of children. Parameters expressing skeletal and dentoalveolar disharmony were checked and compared with control. Additionally, occlusion relationship was evaluated. Maxillary dental age was significantly delayed compared to chronologic age. Several parameters which show skeletal open-bite tendency and skeletal class III malocclusion with maxillary retrusion were statistically significant. Anterior crossbite and edge-bite were expected in most of these cases, but compensation by occlusion and soft tissue was also verified which might mask skeletal class III tendency. Congenital missed or developmentally delayed maxillary first molars might be related with declined growth of maxilla. If developmental disorders of maxillary first molars were verified during clinical examination, careful monitoring of orofacial growth was necessary during puberty and timed orthopedic and orthodontic intervention were considered.
