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.

연생연금보험의 장수리스크에 관한 연구

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.

문제: 퇴원 환자의 문의 전화가 많아지면서 병동 간호사는 이 문의에 응하는 일로 업무량 과다, 전화 상담에 대한 자신감 저하 및 부담 등을 느끼고 있었다. 부적절한 전화문의 관리는 환자와 간호사 모두에게 시간 소모 및 만족도 저하 등의 부정적인 경험을 남길 수 있다. 목적: 전화문의 응대 매뉴얼 구축 및 활용으로 병동 간호사 및 퇴원 환자의 만족도를 향상시키고자 한다. 의료기관: 서울시 종로구에 소재한 대학병원. 질 향상 활동: 표준화된 전화문의 응대 매뉴얼을 개발하였다. 또한 간호사의 업무 효율성 및 지식 향상을 위해 간호사 대상 매뉴얼을 교육하여 실무에서 활용하기 쉽도록 하였다. 개선효과: 표준화된 전화문의 응대 매뉴얼을 안과 병동 간호사와 전보자 및 신규 간호사 교육에 활용할 수 있었다. 간호사의 전화문의 응대 관련 직무 만족도가 향상되었다. 환자 역시 표준화된 매뉴얼에 따라 일치되고 일관성 있는 정확한 정보를 제공받게 되어 환자의 만족도와 이해도가 증가할 것이다.

남효온(南孝溫)의 한시(漢詩)를 통해 본 삶의 방식 - 상처와 치유를 중심으로 -

이현정,이준규,Lee, Hyun-Jung,Lee, Jun-Kyu 한국한의학연구원 2012 한국한의학연구원논문집 Vol.18 No.3

This study aims to examine the life of Chugang Nam Hyo-On (1454~1492) from his Chinese poem and to figure out how he overcame and healed his agony and wound. Nam Hyo-On was one of the Saengyuksin who submitted Sureungbokuiso and spent his whole life with alcohol and wandering. Thus, he is known to be a hermit writer or stranger. He had to suffer poverty during his life thanks to his only one choice. He was weak by nature but also feeble mentally as he always worried about death. In his 30s, he regarded himself as an aged man and always worried about death due to his frequent illness. Sometimes, he used to dream of being forever young. He composed self-elegy poem that is about his death, which is the ever first self-elegy poem in our history. He sent it in his letter to his master Kim Jong Jik (1431-1492) in 1489. His agony and motivation of writing such poem can be conjectured from his master's reply and his self-elegy poem. Nam Hyo-On tried to overcome and heal his real discontent and wound from his literary works. And it seems appropriate to regard him that he attempted to get compensation of his limitation and discontent from literature. We sometimes heal our wound by writings (or literature) and by reflecting through such writings. Nam Hyo-On reminded of his beloved person through his poet writing and healed his fear of wound of death.

월출산 민물가재 생식에 의한 한 가족내 폐흡충증 3례

이현정,선규근,나경희,박선영,김은영,김경심,김용욱,김석일,Lee, Hyun Jung,Sun, Gyu Geun,Na, Kyung Hee,Park, Sun Young,Kim, Eun Young,Kim, Kyoung Sim,Kim, Yong Wook,Kim, Suk Il 대한소아감염학회 2002 Pediatric Infection and Vaccine Vol.9 No.2

폐흡충증은 비록 발생빈도가 현저히 줄어 현재는 드물게 발생하는 질환이 되었지만 아직도 국내에 폐흡충증과 같은 기생충감염의 보고가 있으므로 게장이나 생가재 등의 섭식을 금하여야 할 것이다. 그리고 호산구 증가증을 동반한 치료되지 않은 폐질환에 있어서 비록 객담이나 대변검사에서 충란이 발견되지 않을지라도 폐흡충증에 대한 정확한 병력청취가 필요하며 폐흡충증은 피내반응검사로 간단히 선별검사를 할 수 있고, 면역효소측정법을 이용하여 비교적 정확하게 진단할 수 있기 때문에 관심을 가지고 적극적인 검사 및 치료가 시행되어야겠다. 폐흡충증이 폐결핵과 임상증상이나 방사선학적으로 여러 가지 유사한 소견을 보인다는 점에서 폐결핵과 감별하는 것은 중요할 것 같다. 본 증례들은 전남 영암 월출산 계곡에서 잡은 생가재를 섭식한 후 일가족에서 발생한 폐흡충증으로서 이제까지 폐흡충증의 발생지역으로 보고된 적이 없었던 월출산 계곡을 새로운 폐흡충증의 발생지역으로 보고하며 지속적인 호산구 증가증을 동반한 치료되지 않은 폐질환이 있을 때 폐흡충증과 같은 기생충감염의 가능성에 대해서도 고려해야 할 것이다. Human infection with the lung fluke Paragonimus westermani has become rare in Korea. Human paragonimiasis is caused by eating raw fresh-water crayfishes or crabs infected with larval metacercariae. Recently, we experienced three cases of pulmonary paragonimiasis in a family. They ate raw fresh-water crayfishes that lived in a stream in Wolchulmountain. All the parients had hypereosinophilia and pulmonary infiltrates with pleural effusion or hydropneumothorax, which did not improve on antibiotics. Ingestion of raw crayfishes was a clue for paragonimiasis. Positive results were shown both on intradermal skin test and ELISA for Paragonimus westermani specific IgG. After treatment with praziquantel, the patients showed an improvement. This is the first familial human paragonimiasis, reported from Wolchulmountain in Chonnam Province where there had been no previous cases of paragonimiasis.

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.

Graph Theoretical Analysis of Brain Structural Connectivity in Patients with Alcohol Dependence

이현정,정준형,정성원,Ju Gawon,김시경,손정우,신철진,이상익,Lee Jeonghwan 한국뇌신경과학회 2023 Experimental Neurobiology Vol.32 No.5

This study aimed to compare brain structural connectivity using graph theory between patients with alcohol dependence and social drinkers. The participants were divided into two groups; the alcohol group (N=23) consisting of patients who had been hospitalized and had abstained from alcohol for at least three months and the control group (N=22) recruited through advertisements and were social drinkers. All participants were evaluated using 3T magnetic resonance imaging. A total of 1000 repeated whole-brain tractographies with random parameters were performed using DSI Studio. Four hundred functionally defined cortical regions of interest (ROIs) were parcellated using FreeSurfer based on the Schaefer Atlas. The ROIs were overlaid on the tractography results to generate 1000 structural connectivity matrices per person, and 1000 matrices were averaged into a single matrix per subject. Graph analysis was performed through igraph R package. Graph measures were compared between the two groups using analysis of covariance, considering the effects of age and smoking pack years. The alcohol group showed lower local efficiency than the control group in the whole-brain (F=5.824, p=0.020), somato-motor (F=5.963, p=0.019), and default mode networks (F=4.422, p=0.042). The alcohol group showed a lower global efficiency (F=5.736, p=0.021) in the control network. The transitivity of the alcohol group in the dorsal attention network was higher than that of the control (F=4.257, p=0.046). Our results imply that structural stability of the whole-brain network is affected in patients with alcohol dependence, which can lead to ineffective information processing in cases of local node failure.
