목 적 : 초등학생을 대상으로 야뇨증의 유병율 및 야뇨증 관련된 역학조사를 위하여 본 연구를 실시하였다. 방 법 : 경기도 수원지역에 있는 두 초등학교(공립 및 사립학교 각 1개교)에 재학 중인 총 1,514명의 학생들을 대상으로 2006년 12월 한 달간 학생부모 설문조사를 통하여 야뇨증과 관련한 역학조사를 실시하였다. 성별, 연령별, 체격지수, 오줌참기 습관, 가정경제수준 등이 야뇨증 유병율에 미치는 영향을 조사하였다. 결 과 : 전체 1,514명의 학생에게 설문하여 1,063명(70.2%)이 응답하였으며, 응답학생 중 93명(8.7%)에게 야뇨증이 있는 것으로 조사되었다. 학교별 유병율을 보면 공립학교 546명 중 48명(8.8%), 사립학교 517명 중 45명(8.7%)에서 야뇨증이 있었다. 공립과 사립 학교간 월 가정수입 차이는 현격하였으나 이에 따른 유병율 차이는 없었다. 야뇨증의 빈도가 남아에서 8.1%, 여아에서 9.6%로 여아에서 더 높은 경향을 보였으나, 통계적으로 유의한 차이는 없었다. 오줌참기 습관이 있는 학생의 경우 22.1 %로 정상인 학생 5.6%에 비하여 유의하게 야뇨증 빈도가 높았다. 신장 및 체중의 백분위 값은 야뇨증이 있는 학생 군이 정상 학생 군에 비하여 작았으나 통계적으로 유의하지는 않았다. 야뇨증이 있는 93명중 25명(26.9%)만이 야뇨증 치료차 병원을 방문한 적이 있음을 볼 때, 야뇨증치료의 필요에 대한 부모의 인식이 매우 낮음을 알 수 있었다. 연령에 따른 야뇨증 유병율을 살펴보면 연령이 증가할수록 연평균 2.0%씩 유병율이 감소하는 것으로 나타났다. 결 론 : 수원지역 2개교 초등학생을 대상으로 한 조사에서 야뇨증의 평균 유병율은 8.7%였으며, 7세 무렵 12.1%에서 매년 2.0%씩 감소하여 13세까지 거의 소실되는 것으로 보였다. 낮 동안에 배뇨억제 습관이나 가뭄뇨가 있는 아동에서 야뇨증 유병율이 높음을 볼 때, 배뇨조절 교육 및 훈련의 확대가 필요한 것으로 판단된다. 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.

오창수 ( Changsu Ouh ),이현정 ( Hyunjung Lee ) 한국계리학회 2017 계리학연구 Vol.9 No.2

본 연구에서는 미래사망률의 추정에 자주 사용되는 Lee-Carter(LC)모형을 이용하여 미래사망률을 산출하고, 제8회 경험생명표 적용 대비 보험사에서 판매하는 연생형 연금보험에서의 준비금을 기준으로 장수리스크 변화를 비교 분석하였다. 산출결과 주피보험자 40세(남자)일 때 현행 준비금 대비 장수리스크를 고려한 준비금 증가비율(V_LR^LC)이 단생형 7.842%, 연생형 8.358%로 분석되어, 연생형 연금보험에서 장수리스크가 더 큰 것으로 나타났다. 이는 연생형 연금보험에서는 주피보험자 및 종피보험자의 사망률로 산출된 연금이 지급되므로, 주피보험자 및 종피보험자의 사망률 개선영향을 받기 때문이다. 또한, 연생형 연금보험에서는 주피보험자 및 종피보험자의 연령차가 클수록 총 연금지급기간이 길어지기 때문에 장수리스크는 증가하는 반면에, 연금지급 보증기간이 길수록 사망률에 영향을 받지 않는 연금지급기간이 길어 장수리스크는 감소하는 것으로 분석되었다. Longevity risk is the risk the insurance company has to implement cash flow for the future as the mortality has improved under the Solvency Ⅱ. In this paper, the longevity risk is calculated in joint and last survivor annuity product applying the mortality from Lee-Carter model(LCM) comparing from the one from the 8th experience mortality table(EMT). We show estimation parameters of LC model using Korean mortality data from year 2001 to 2015. Longevity risk of joint and last survivor annuity was 8.358% of Best Estimate Liability(BEL) by the 8th experience morality table(EMT) while longevity risk of single life annuity was 7.842% of BEL by the 8th experience morality table(EMT). This is because in joint and last survivor annuity the mortality of both the insured and the second insured affects the payment of annuity. The mortality improvement influences both the insured and the second insured in joint and last survivor life annuity but in the single annuity the morality of the insured is the only factor affected. We also see the change of longevity risk as the discount rate, age, the gap of ages between the insured and the second insured and the different annuity payment guaranteed period so on.

The functions and uses of existing buildings are not properly changing as modern life needs. As a result, the frequent reconstruction(construction after removal) of existing buildings have been done but it became more and more difficult because of strengthening of regulations and systems concerning construction. And also it has several disadvantages like lower plot ratio and site coverage than existed buildings, enormous construction cost, production of waste-construction materials and thoughtless consumption of natural resources, which gives rise to environmental pollution. Therefore renovation is brought to the fore. In Korea, many business buildings were constructed in 1960s-1970s, during the period of high growth. Such buildings needs to be repaired in whole. It is caused by the change of social, economic, and cultural conditions and deterioration of equipments. Therefore renovation meets some necessary conditions; recovery of building functions and extension of building life span. In case study, the present state of renovation in business buildings is 1) Basic safety, for example, fire prevention and crime prevention, is great important. 2) Advanced technology, INS(international news service), IBS(Intelligent Building System), and internationalization, is pursued for adapting to multimedia ages. 3) It tries to promote proficiency, and to save the energy using spatial environment and natural energy(light and sound). Also, improving comfortable level of users and installing equipments for physically handicapped person needs to be considered.

Handles are very essential element to satisfy function of furniture except for furniture without doors. Moreover, handles of furniture tend to have not only functions for opening and shutting but also decorations for furniture. Among various hardware for furniture, handles are the one who influence furniture's design most. Yet, cases of damages occur due to the fact that there are many copying. Handles have short lives, so that it is economically quiet burden to develop new products in Korea. Therefore, this study aims to inspire necessity of investment for handles and other hardware's development by classifying types of handles, systemizing basic knowledge of design for furniture handles, and realizing the importance of handles within domestic demand.

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 submucosal 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 submucosal midazolam increased the success rate in sedation and the vital signs were stable during sedation.
