Marfan syndrome (MFS) is an inherited connective tissue disorder with a mutation in the fibrillin-1 (FBN1) gene. Fibrillin is a major building block of microfibrils, which constitute the structural component of the connective tissues. A 10-year-old girl visited our hospital with the chief complaint of precocious puberty. According to her medical history, she had a pulmonary wedge resection for a pneumothorax at 9 years of age. There was no family history of MFS. Mid parental height was 161.5 cm. The patient's height was 162 cm (>97th percentile), and her weight was 40 kg (75th-90th percentile). At the time of initial presentation, her bone age was approximately 11 years. From the ophthalmologic examination, there were no abnormal findings except myopia. There was no wrist sign. At the age of 14 years, she revisited the hospital with the chief complaint of scoliosis. Her height and weight were 170 cm and 50 kg, respectively, and she had arachnodactyly and wrist sign. We performed an echocardiograph and a test for the FBN1 gene mutation with direct sequencing of 65 coding exons, suspecting MFS. There were no cardiac abnormalities including mitral valve prolapse. A cytosine residue deletion in exon 7 (c.660delC) was detected. This is a novel mutation causing a frameshift in protein synthesis and predicted to create a premature stop codon. We report the case of a patient with MFS with a novel FBN1 gene missense mutation and a history of pneumothorax at a young age without cardiac abnormalities during her teenage years.

In this study, changes in the timing of puberty physicality and mentality and beauty characteristics of high school students were characterized for high school students and the general high school population in order to distinguish between interest and beauty and beauty products and beauty behavior for comparative analysis. First, for beauty characteristics of high school students and the general high school population, differences in beauty action and beauty characteristics of high school students were higher than this beauty behavior. Secondly, for the high school students and high school beauty characteristics of general high school population for beauty and beauty products, the difference between interest and multi-functional beauty products that characterize high school students has beauty and beauty products with multi-functional beauty products interest being high. Third, high school students and high school beauty characterize the general high school population of beauty is different from behaviors on its factors with common factors including the psychological gratification 'for reasons of appearance management looks for reasons that do not' have time to manage the response. Two groups of factors that characterize the differences in appearance and beauty as areason to manage high school students interested in the 'style' order, high school students do not manage reasons for lack of interest in the 'general' as a response. Beauty characteristics of high school students in the beauty, beauty products, and products demonstrated a multi-functional information gathering with lots of attention, and much ability can have an active beauty behavior. The general high school population lacks the ability to gather information in accordance with interested beauty behavior being passive. The two groups and beauty behavior patterns of consumption could see that a difference occurred.

Purpose: Recently, vitamin D insufficiency has increased and has been correlated to growth and puberty in children. This study was conducted to find the prevalence of subclinical vitamin D insufficiency and its influence on school-aged children in Korea. Methods: The subjects of this study were 397 children aged 7 to 15 years who had been tested for 25-OH vitamin D3 among the outpatients of the Department of Pediatrics in Eulji General Hospital from March 2007 to February 2011. Data for age, sex, comorbidities, serum 25-OH vitamin D3, height, weight, body mass index (BMI), and sunlight exposure time were collected before and after 3 months of vitamin D administration, retrospectively. Results: Vitamin D insufficiency was present in 343 (86%) of the subjects. In the vitamin D insufficient group, chronological age was $8.96{\pm}1.72$ years, mean height (z-score [z]) was $0.51{\pm}1.26$, mean BMI (z) was $0.81{\pm}2.20$, and bone age was $10.26{\pm}1.75$ years. In the vitamin D sufficient group, chronological age was $9.61{\pm}1.77$ years, mean height (z) was -$0.66{\pm}0.98$, mean BMI (z) was -$0.01{\pm}1.16$, and bone age was $9.44{\pm}2.12$ years. A paired t-test showed that three months after vitamin D administration, the mean 25-OH vitamin D3 level in the insufficient group increased to $24.38{\pm}10.03$ ng/mL and mean BMI (z) decreased to $0.67{\pm}1.06$. Conclusion: In Korean school-aged children, vitamin D insufficiency were relatively higher and may be closely related with higher BMI. Insufficient rise of the level of vitamin D after supplementation suggest the new supplementation guidelines, especially for Korean children.

Malignant ovarian germ cell tumors (MOGCT) are rare neoplasms that most frequently occur in women at a young reproductive age. There have been limited data regarding this disease from Southeast Asian countries. We therefore conducted a retrospective study to analyze the clinical characteristics and the treatment outcomes of MOGCT treated at our institute between January, 2003 and December, 2012. Seventy-six patients were recruited from this period with the mean age of 21.6 years and 11.8% were pre-puberty. The two most common symptoms were pelvic mass and pelvic pain. Two-thirds of the studied patients presented at an early stage. The most common histology was immature teratoma (34.2%) followed by endodermal sinus tumor (28.9%), dysgerminoma (25%), mixed type (10.5%) and choriocarcinoma (1.3%). Over 80% of these patients received fertility sparing surgery and about 70% received adjuvant chemotherapy with the complete response rate at 73.3% and partial response at 11.1%. The most frequent chemotherapy was BEP regimen (bleomycin, etoposide, cisplatin). With the mean follow up time at 56.0 months, 12 patients (15.8%) developed recurrence and only an advanced stage was the independent prognostic factor. The ten year progression free survival (PFS) and overall survival rate of our study were 81.9% and 86.2%, respectively. In conclusion, MOGCT often occurs at a young age. Treatment with fertility sparing operations and adjuvant chemotherapy with a BEP regimen showed a good outcome. An advanced stage is a significant prognostic factor for recurrence.

The present study analysed the various productive and reproductive characteristics of 1/2 Pabna Milking Cows (PMC)-1/2 Sahiwal (S) and 1/4 PMC-3/4 S collected from the Pabna milkshed area at Baghabarighat, Sirajgonj, Bangladesh. The studied traits were birth weight (BWT), age at puberty (AP), number of services per conception (NSC), post partum heat period (PPHP), gestation period (GP), daily milk yield (DMY), lactational production (LP), lactation length (LL), fat percentage and solids-not-fat percentage (SNFP). Five individual Sahiwal sires were used for the upgrading of Pabna Milking Cows. The used data covered from 1987 to 1994. Least-squares analysis of variance showed that genetic group had a significant effect on BWT (P < 0.05), AP (p < 0.01), DMY (p < 0.01), LP (p < 0.001), LL (p < 0.05), FP (p < 0.05) and SNFP (p < 0.01). Genetic group had non-significant effect on NSC, GP and PPHP. The effect of sire was significant on BWT (p < 0.01), NSC (p < 0.01), LP (p < 0.05) and LL (p < 0.05). The AP, NSC, DMY, LP, LL and SNFP were higher in 1/2 PMC-1/2S cows; BWT and PPHP were higher in 1/4 PMC-3/4S but GP and FP were almost same in both genetic groups. From this study it may be concluded that production and use of 1/2 PMC-1/2S would seem more profitable for commercial milk production in the Bangladesh Milk Producers' Cooperative Union Limited (BMPCUL) area and at the same time emphasis should be given on rigorous sire selection.

본 연구는 New Zealand White 수토끼에서 춘기발동 기간 동안에 혈청내 IGF-I(insulin-like growth factor-I)과 GH(growth hormone) 수준의 변화, 정자 형성에 따른 정소내 세포 구성 변화 및 이들 측정치들 간에 관계를 조사하기 위하여 실시되었다. 주령과 관련된 정소내 세포의 DNA 함량 변화 조사를 위하여 $10\~28$주령 수토끼 정소 조직의 fine-needle biopsy를 flow cytometry(FCM)로 분석하였다. 생체중은 $12\~20$주령 때 크게 증가되었고(P<0.05), 28주령 체중은 3.4kg이었다. 혈청 IGF-I 수준(451.3ng/mL)은 20주령에서 가장 높았으며(P<0.05), 그 후 낮은 수준으로 유지되었다. 혈청 GH 수준은 183.3pg/mL으로 다른 주령 때보다 현저히 높았으며(P<0.05), 상승시기가 IGF-I보다는 다소 빨랐다. 정소 조직세포 중 1C-세포의 상대적 비율은 18주령 때 $48.2\%$로 16주령보다 크게 상승되었고(P<0.05), 주령 증가와 더불어 $68\%$로 증가되었다. 2C-세포 비율은 18주령 때 $26.8\%$로 16주령의 $54.3\%$보다 현저히 낮았다(P<0.05). 4C-세포 비율은 18주령 때 $9.9\%$를 제외하고 $2\~6\%$를 유지하였다. 이상 결과에서 토끼는 춘기 발동 개시가 약 18주령에 일어나고 이 기간 중 IGF-I과 GH 수준의 변화가 나이 또는 체성장과 관계가 있었으며 그 영향이 정자 형성과 관련이 있음을 알 수 있었다. Fine-needle biopsy와 연계된 FCM은 춘기 발동 개시와 관련된 정자의 형성 과정을 평가하는데 매우 정확한 방법임을 확인할 수 있었다. 평균 CK-MB치는 $17.4\pm29.7\;IU/L$였다. 전체적인 이식편의 개통률은 $99.1\%\;(214/216)$(좌내유동맥 $100\%$, 요골동맥. $98.4\%$, 우내유동맥: $100\%$)를 보였다. 결론: 다중 복합 Y 동맥 이식편을 이용한 완전 동맥 무인공 심폐 바이패스 관상동맥우회술을 기술적인 문제점 없이 시행할 수 있었으며, 우수한 초기 임상 결과와 개통률을 보였다. 저자들은 특히 심장의 둔각 모서리 부위의 우회술시에 기존의 연쇄 문합에 비해 기술적으로 더 용이하며 복잡한 관상동맥우회술이 필요한 환자에게도 도움이 될 것으로 생각한다.보존하는 일에 등한시하여 왔다. 이 때문에 우리 민족 고유의 뿌리를 점차 잃어가고 있다. 이러한 시점에서 도시노점상을 정리하기 위한 목적으로 정부에서 도시 5일장을 개장한 것은 역사의 아이러니라 아니할 수 없다. 이렇게 정부주도로 개장된 5일장이 운영되어 온 지 2년이 되어가고 있다. 개장 초기에는 시에서의 지원도 적극적이고 소비자들의 호응도 좋았으나, 최근에 들어 활성화의 속도가 둔화되면서 도시 5일장의 개념을 재정립할 필요성이 제기되고 있다. 정부의 주도로 시작된 5일장이므로 정부의 적극적인 추진하에 풍물시장 번영회와 활성화 방안을 모색해야 한다. 쌍다리 풍물시장의 5일장을 활성화하기 위하여 도시 5일장의 개념을 ${\ulcorner}$국민들의 생활수준이 향상되고 여가를 즐길 수 있는 여건이 형성되고 있으므로 전통문화(향토문화)를 유지하고 시민들의 정서함양에 기여할 수 있는 여가공간 조성${\lrcorner}$으로 규정해야 한다. 이러한 개념 하에 5일장의 주체를 명확히 하기 위해 시청 지역경제과를 중심으로 지자제의 실시에 발맞춰 지역특색에 맞게 5일장을 활성화하기 위한 전학을 수립해야 한다

The purpose of this study was to examine the sex-consciousness and sexual values of school children by geographic region. It's specifically attempted to make a comparative analysis of sex-consciousness and sexual values between urban and rural elementary schoolers to help provide efficient sex education for them to build the right sexual values. The subjects in this study were 400 elementary schoolers in their sixth year of elementary schools located in Danyang-gun and Chungju city, north Chungcheong province. After a survey was conducted, answer sheets from 387 students that were analyzable were analyzed. For data handling, SPSS program was employed, and t-test was utilized to see if there's any differences between the urban and rural elementary school youngsters in sex consciousness and sexual values. And $x^2$ test was used to make a comparative analysis of their view of sex education. The findings of the study were as follows : First, regarding sex-consciousness, they had general knowledge on sex. Especially, they were highly aware of sexual violence and the generation of baby, but many of them didn't know about where and how egg cells were produced. This indicated that systematic education should be offered in various ways. Concerning geographic gap, there was a significant difference in sexual knowledge between the urban and rural students. As to sexual attitude, they took a relatively positive attitude toward display of affection or sex-related talk on TV or in movies, as they viewed it as natural. This finding implied that the elementary schoolers were recipient toward sex and took an active attitude toward sexual expressions. Concerning geographic gap, there was no difference between the rural and urban students. As for sexual practices, the largest group of the students had a liking for the opposite sex, which showed that their needs for sex were unveiled in the course of having some trouble due to the other sex rather than through firsthand experiences or activities. As to geographic gap, there was a significant difference between the urban and rural students in that regard. Besides, the urban students put their sex-consciousness in practice more often than the rural students did. After they are educated to build the right sexual values, systematic sex-education programs should also be offered for them to be exposed to sustained sex education and to team how to apply their sex-consciousness to real life. Second, as for sexual values, the school children had relatively positive and equalitarian sexual values. Regarding geographic gap, there were significant gaps between the two groups' view of the opposite sex, sexual roles and chastity. Concerning view of the opposite sex, they attached more importance to the inner aspects of the opposite sex than his or her look, and they wanted to date in a natural manner. Regarding sexual roles, they were relatively well cognizant of gender equity and the importance of male and female roles. As to view of chastity, they looked upon sex as natural, not as what's ugly or ashamed of. Third, concerning their outlook on sex education, approximately more than half the students felt the needs for sex education, and there was a significant difference between the urban and rural students. They wanted to receive education about the prevention of sexual violence and physical changes during puberty the most, and there was a significant gap between the urban and rural students in this aspect. As to the time for sex education, they thought that students should start to be exposed to sex education in their fifth or sixth year. This finding signified that fifth or sixth graders who were in the beginning of puberty started to have a lot of interest in their own physical changes. Therefore, sex education would produce better effects when it's provided to fifth or sixth graders. Nearly half them preferred single-gender class when they received sex education, and there's no gap between the urban and rural students in that regard.

The goal of this research was to provide the basic data of sexual education for late schooler by finding out what they want to know about sex, or to see, if any, its relevancy between female and male students and between each grade. The sample for this research was a total of 453 students in 4th, 5th and 6th grade from 12 different classes at two elementary schools which were located in C city and in B province. The children were requested to write down three points on what they want to know or to learn most about sex, and their answers were put through two analytical stages in order to classify and to examine. The followings are the conclusions from the data. 1. The female cluster took 44.2% out of the whole sample, and there were 151 students per each grade. The specific girl ratios for each grade were 42.4%, 50.3% and 39.7% respectively. 2. It was noted that a total of 1,195 questions were gathered from the students writings, 45% of the questions was raised by the female students. The 4th grade students raised 432questions (43.8% by the girl) while the 5th. and the 6th grade students raised 387 (53.2% by the girl) and 376 questions (42.3% by the girl) respectively. The average number of questions per students was 2.6 while the female students raised 2.8 questions which was more than the average 2.5 questions by male students. It was the 4th grade female student cluster, which raised the most question (3.0) while the 6th grade male students raised the least question (2.4) in average. 3. The questions raised by the children could be divided into seven categories of the knowledge need on sex. They were Reproduction (310 questions, 25.9%), Sexual Culture (230, 19.2%), Concept of sex (125, 18.0%), Changes of Puberty (172, 14.4%), Sexual Health (119, 10.0%), Anatomy and Physiology of Reproductive System (78, 6.5%) and Sexual Tendency and behavior (71, 5.9%). 4. 'Reproduction' was the most frequently raised questions not only by both sex groups but also by the 5th grade students. Both sexes in the 4th grade showed the highest interest in Sexual Culture while it was Changes in Puberty for the both sexes in the 6th grade. The knowledge need on sex of the children indicated what they understand sexuality. They apprehended sex as sex, gender and sexuality in an inclusive way. They showed a major interest in the biological sex and the sexual activities. It seems that the children managed to understand clearly the meaning of gender, furthermore, they even pointed out that the streotyped sex role, patrimonial system and the sexual discrimination were unreasonable. The students possessed not only the least but also the most negative understanding in regard of sexuality. Two suggestions were made from the above conclusions for the practical sex education as well as its research. 1. For the practice: The sex education for the elementary upper grade school student should be relevant with their cognitive characteristics, also it should be more specific on the reproductive organs of both sexes, the actual scenes of the pregnancy and child delivery procedures. The gender concept should be added to the biological sex education, which will lead them to understand the unreasonableness of today's male-superior phenomenon and correct them. It is also necessary to develop educational programs for this age group so as to help them to understand sex in the sense of sexuality as well. 2. For the research: It is not easy to draw out a through conclusion since this study was carried out as one-time data collection. Yet it is undeniably helpful for the sex education if we can understand what the children want to know about sex, how much they know about it by conducting deep-interview researches through a small number of sample.

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.
