Purpose : The purpose of this study was to investigate the prevalence of enuresis in association with voiding habits and socioeconomic status in elementary school children. Methods : A dynamic survey was done of 1,514 students from two elementary schools in Suwon, Korea in December 2006. Data regarding gender, age, height and weight, voiding habits, and monthly family incomes were gathered and analyzed to discover any correlation with the incidence of enuresis. The percentile value of height or weight was extrapolated from the standard population curve. Results : Among 1,514 children, 1,063 (70.2%) answered and returned the questionnaires. Overall, the prevalence of enuresis was 8.7% and there was no difference between the public (8.8%) and private school (8.7%). The family incomes of the students from the two schools differed greatly from each other, but there was no difference in the prevalence of enuresis between the two schools. Children with a habit of void-holding showed a higher prevalence of enuresis. No significant correlation was found between the prevalence of enuresis and the height and weight percentile of children. Experience with hospital visits was low among enuretic children (20.8%), suggesting that Korean parents tend to neglect treatment of enuresis for their children. The prevalence of enuresis decreased by 2.0% each year, as school children aged. Conclusion : The overall prevalence of enuresis among elementary school children in Suwon district was 8.7%. The 12.1% prevalence of enuresis at the seven years came down gradually, to be nil at the age of 13. Infrequent urination or void-holding was assumed to be one of the important factors causing enuresis in elementary school children.

The purpose of the study was to investigate whether there are differences in confrontation naming ability, generative naming ability, hearing handicap, and depression in community-dwelling elderly by age group, and whether there is any correlation among them, and to find out what factors explain the two naming abilities (confront and generative) of the elderly. Sixty-five community-dwelling elderly people participated: 65~74 years were classified into young-old; 75~84 years into old-old; and 85 years and over into oldest-old. K-BNT-15 for the confrontation naming ability, animal naming test for the generative naming ability, K-HHIE for the subjective hearing handicap, and GDS for the subjective depression were administered. First, there was a statistically significant difference in confrontation naming and depression levels according to age groups. Second, there was a positive correlation between chronological age and subjective depression level and between subjective hearing handicap level and subjective depression level, and a negative correlation between education level and subjective depression level. Third, the confrontation naming score was explained by age, and the generative naming score was explained by subjective depression level. The results show that naming abilities, subjective hearing handicap, and subjective depression level are not simply the result of normal aging and that a convergence approach is needed in various fields to solve the issue.

이현정,나용찬,양지훈,Lee, Hyun-Jung,Na, Yong-Chan,Yang, Ji-Hoon 한국정보처리학회 2010 정보처리학회논문지B Vol.17 No.2

본 논문에서는 분산된 거대한 네트워크상의 데이터에서 유용한 정보를 추출하는 새로운 마이그레이션 조절방법을 이용한 유전 알고리즘을 제안한다. 제안된 알고리즘의 주된 아이디어는 부분 개체군 사이에서 개체들의 이동에 필요한 파라미터들을 적응적으로 결정하는 것이다. 또 이동된 개체들이 새로운 부분 개체군에서 도태되지 않고 적응 할 수 있기 위한 방법을 제시한다. UCI 기계학습 관련 데이터 셋에서 중앙 집중적 단일 유전 알고리즘과 제안된 알고리즘을 비교하기 위해 여섯 개의 데이터를 사용했다. 결론적으로 분산 유전 알고리즘을 적용한 특징 부분 집합이 단일 유전 알고리즘을 적용한 것 보다 좋은 성능을 보였다. We present a new distributed genetic algorithm that can be used to extract useful information from distributed, large data over the network. The main idea of the proposed algorithms is to determine how many and which individuals move between subpopulations at each site adaptively. In addition, we present a method to help individuals from other subpopulations not be weeded out but adapt to the new subpopulation. We used six data sets from UCI Machine Learning Repository to compare the performance of our approach with that of the single, centralized genetic algorithm. As a result, the proposed algorithm produced better performance than the single genetic algorithm in terms of the classification accuracy with the feature subsets.

이현정,박기상,송해범,이택후,조영래,전상식,Lee, Hyun-Jung,Park, Kee-Sang,Song, Hai-Bum,Lee, Taek-Hoo,Cho, Young-Lae,Chun, Sang-Sik 대한생식의학회 2002 Clinical and Experimental Reproductive Medicine Vol.29 No.1

Objective: To evaluate whether co-culture of oocytes on vero cell monolayers from Day 0 (Day 0 group) after egg retrieval results in an increase in developmental capacity such as fertilization rate, embryo quality, blastulation and clinical pregnancy rate compared with co-culture of oocytes from Day 1 (Day 1 group). Methods: Sperms were treated with Hams F-10 supplemented with 10% human follicular fluid (hFF). Vero cells for co-culture were prepared in TCM-199 with 10% FBS. Oocytes were co-cultured from Day 0 and fertilized oocytes were co-cultured from Day 1 on vero cell monolayers in DMEM with 10% and 20% hFF, respectively after egg retrieval. On day 1, 2 and 5, fertilization rate and grade of embryos and blastocysts were evaluated. Results (fertilization rate, cleavage rate, grade of embryos and blastocysts and pregnancy rate) were considered statistically significant when p value was less than 0.05 using t-test and $x^2$. Results: In sibling oocytes of same cycles, no differences were found in fertilization rate (94.6 vs. 91.4%), cleavage rates (94.6 vs. 91.4%), embryo grade (on day 2 and 3) and blastulation (65.6 vs. 57.0%) and their grade. In different oocytes of different cycles (patients), no differences were found in fertilization (79.8 vs. 78.3%), cleavage rates (77.7 vs. 76.4%) and blastulation (56.0 vs. 45.3%), but pregnancy rate was higher in the Day 0 group than in the Day 1 group (60.0 vs. 42.9%). Conclusions: This study revealed that the embryonic development capacities were not affected by the different co-culture time in the sibling oocytes of same cycles. Although no statistical significance, because of small size of study, there was a trend for higher pregnancy rates in Day 0 group compared to Day 1 group in different oocytes of different cycles.

This study aimed to investigate the association between interest in beauty care and dietary behaviors of 581 (analysis rate 96.0%) high school girls in Incheon using a survey done in May 2019. Based on the degree of interest in beauty care, subjects were classified as "Beauty care group (n=346)", and "Non-beauty care group (n=235)". The mean age of the subjects was 16.5 years old. The beauty care group had significantly lower BMI than the non-beauty care group (p<0.01). The beauty care group showed a significantly higher interest in weight control than the non-beauty care group (p<0.001). The most time-consuming preschool morning activity in the beauty care group was beauty care, while that of the non-beauty care group was eating breakfast (p<0.001). The beauty care group had significantly higher frequency of exercise than the non-beauty care group (p<0.05). The number of individuals who skipped breakfast was significantly higher in the beauty care group. In addition, the beauty care group had a significantly higher frequency of taking morning snack, convenience food (p<0.01), sweet snacks (p<0.05), and processed beverages (p<0.05) than the non-beauty care group. Our result findings provide important information on the priority groups for nutrition education based on beauty care interest.

이현정,백광우,정상혁,Lee, Hyun-Jung,Baek, Kwang-Woo,Jung, Sang-Hyuk 대한치과마취과학회 2008 Journal of Dental Anesthesia and Pain Medicine Vol.8 No.1

Recently combining regimen of minimal doses of chloral hydrate, hydroxyzine and midazolam is good in sedation of children. Midazoalm, water soluble benzdiazepine, has rapid onset and relatively short duration of action. And midazolam has prospective amnesic effect. With these advantages midazolam is popular in conscious sedation for children. This study was to reveal the dose-dependency of behavior and physiologic effects of sublingual midazolam. Sedation records were surveyed retrospectively, of which the patients admitted from April, 2005 to July, 2007. we assigned three groups according the dose of midazolam, 0.1 mg/kg, 0.2 mg/kg and 0.3 mg/kg, respectively and the behavioral evaluation was analyzed with Houpt scale statistically. Combined sublingual midazolam increased the success rate in sedation and the vital signs were stable during sedation.
